- the interfolding portions 13 are secured to the fixing plate 43.
- the vertical position of the receptacle 10a approximately corresponds to that of the interfolding portions 13, and that is when the bottom surface of the receptacle 10a of the table 10 is slanted relative to the top faces 13a of the interfolding portions 13. More specifically, the rear bottom step 19a is slanted higher relative to the front bottom step 18a.
- the front face heater 15 is arranged at the side where the folder 17 is provided relative to the table 10. In other words, the front face heater 15 is located outside of the front end face 81 of the CD case 80 mounted on the table 10.
- the front face heater 15 is constituted, as a cross section of that is shown in Fig. 3, by a tubular member 37 made of resin, rubber or the like of tubular shape having elasticity and an electrically-heated wire 38 which is a heating element embedded in the tubular member 37. Electrifying to the electrically-heated wire 38 generates heat in the wire 38, and the heat is conducted to the tubular member 37, thereby heating the resin film 90 contacting with the tubular member 37 to fuse the film 90 mutually, as described below.
- an adhesive being fusible by heating may be applied in advance on the film 90 that is a wrapping material to heat the adhesive for fusing.
- the front face heater 15 is retained by the retainer plate 39, which is of plate-like member.
- the front face heater 15 is attached to the edge of the retainer plate 39 to cover the entire area of the edge adjacent to the table 10 of the retainer plate 39.
- the retainer plate 39 is made of resin with heat resistance, so that the heat generated by the electrically-heated wire 38 is not easily conducted to the retainer plate 39.
- the retainer plate 39 is movable in the width direction toward the table 10, and is urged in a direction away from the table 10 by an urging member not shown.
- the retainer plate 39 has a handle 40 secured thereto. Only when the handle 40 is pushed toward the table 10, the heater 15 is moved toward the table 10, and when pushing is stopped, the handle 40 moves back in a direction away from the table 10 by the urging member.
- the front face heater 15 is located above the front bottom step 18a and adjacent to the front end face 81 of the CD case 80 mounted on the table 10. Then, the front face heater 15 is moved toward the table 10 to press the front end face 81 of the CD case 80.
- the front face heater 15 is also movable toward the table 10. In this case, the front face heater 15 is moved between the front bottom step 18a and the front top step 20.
- the side face heaters 16 are arranged on either outside in the width direction of the table 10.
- Each of the side face heaters 16 is constituted, as a cross section of that is shown in Fig. 4, similar to the front face heater 15.
- Retainer plates 39 of the side face heaters 16 are located at a higher level than the interfolding portions 13 and movable in the longitudinal direction toward the table 10. When being moved toward the table 10 at the lower position, the side face heaters 16 are moved toward the edges of either side of the table 10, and to a position above and adjacent to outside of the width direction of the receptacle 10a.
- the side face heaters 16 are urged in a direction away from the table 10 by an urging member not shown.
- the retainer plates 39 of the side face heaters 16 each are provided with a handle 40. Only when the handles 40 are pushed toward the table 10, the side face heaters 16 are moved toward the table 10. In this way, the side face heaters 16 have the same movements to the front face heater 15.
- the resin film 90 for use in wrapping has a width a little wider than that of the CD case 80 and a length more than twice the total amount of the length and thickness of the CD case 80.
- a material of the resin film 90 is not limited, though a resin made of ethylene or polypropylene, a drawn film, or the like may be employed.
- the mounting table 10 is located at the upper position and the frame 22 and the front face folder 17 are located away from the table 10.
- the resin film 90 is placed on the table 10. More specifically, an end of the film 90 in the longitudinal direction is to be adjacent to the front bottom step 18a so as to cover the entire area of the receptacle 10a therewith. The film 90 is placed in this way, thereby covering the front bottom step 18a and the rear bottom step 19a. A distance between the end of the film 90 in the longitudinal direction and the front bottom step 18a is to be shorter than the thickness of the CD case 80.
- the CD case is mounted on the film 90 to conform to the receptacle 10a. That ensures, as shown in Fig. 6, that the film 90 is placed between the CD case 80 and the front bottom step 18a, so that the film 90 is folded along the front bottom step 18a and toward the front end face 81 of the CD case 80. Similarly, the film 90 is placed between the CD case 80 and the rear bottom step 19a, so that the film 90 is folded along the rear bottom step 19a and toward the rear end face 82 of the CD case 80. The bottom face 84 of the CD case 80 is covered with the film 90.
- the resin film 90 is folded back to cover the top face 83 of the CD case 80.
- the length of the film 90 is a little more than twice the total amount of the length and thickness of the CD case 80, its end covers the top face 83 of the CD case 80.
- the film 90 covers the rear end face 82, the top face 83, and the bottom face 84, and the opposite ends of the film 90 in the longitudinal direction come to the front end face 81.
- the movable folder 17 is pivotally moved toward the table 10, thereby making the front top step 20 take its position facing to the front bottom step 18a in the thickness direction.
- the front top step 20 of the folder 17 folds the film 90 protruded from the top face 83 toward the front end face 81, so that the film 90 partly overlaps as in the state shown in Figs. 8 and 9B. At this time, slightly pulling the film 90 toward the front end face 81 enables a more definite wrapping with the film 90 close to the CD case 80 without surface waviness.
- the overlapped film 90 is fused to be bonded by the front face heater 15. More specifically, the electrically-heated wire 38 of the front face heater 15 is energized for heat generation, whereby the tubular member 37 reaches a high temperature, and then the handle 40 is moved in a direction indicated by arrows in Figs. 9A and 9B to bring the tubular member 37 in contact with the overlapped film 90, which becomes a high temperature and is fused. Once being fused, the film 90 does not return to the original condition by force of restitution even the folder 17 is put back into place.
- the CD case 80 is covered with the film 90 at its front end face 81, its rear end face 82, its top face 83 and its bottom face 84, whereas the left side face 85 and the right side face 86 have the film 90 protruded therefrom in the width direction.
- the film 90 protruded from the right and the left side faces 86 and 85 of the CD case 80 is interfolded.
- a method of interfolding at the right and the left side faces 86 and 85 will be described only about the case of the right side face 86, and as for the case of the left side face 85, a description is omitted because of the similar case due to a symmetric shape.
- the table 10 is at the upper position, that is, the receptacle 10a of the table 10 is located at a higher level than the top face 13a of the interfolding portion 13. Consequently, the film 90 protruded in the width direction is also located at a higher level than the top face 13a of the interfolding portion 13.
- the distal ends 11a of the first projections 11 are located in front of and back of the protruded film 90.
- a front end face protruded part 91 protruded from the front end face 81 and a rear end face protruded part 92 protruded from the rear end face 82 among the protruded film 90 are interfolded inward.
- a top face protruded part 93 protruded from the top face 83 and a bottom face protruded part 94 protruded from the bottom face 84 are slightly transformed in a direction where the thickness direction extends, upon interfolding of the front end face protruded part 91 and the rear end face protruded part 92.
- pivotally moving the frame 22 toward the table 10 leads through the state shown in Figs. 13 and 16 to Figs. 14, 15, and 17, thereby locating the second projection 12 adjacent to the right side face 86 of the CD case 80. That is when, as shown in Fig. 13, the top face protruded part 93 is interfolded downward by the second projection 12. And when the second projection 12 is moved toward the table 10 and let downward, the distal end 12a of the second projection 12 exceeds an upper side 86a of the right side face 86 of the CD case 80, being slanted. Thus, a point where the top face protruded part 93 is interfolded proceeds from a front side (the right as viewed in Fig. 13) to a rear side (the left as viewed in Fig. 13) gradually, thereby enabling a smooth interfolding with little catch.
- the knob 25 of the support 23 is operated so as to move the table 10 from the upper position to the lower position.
- the bottom face protruded part 94 is located at higher level than the top face 13a of the interfolding portion 13, and then, when the table 10 is moved to the lower position, the bottom face protruded part 94 is interfolded upward, so the top face protruded part 93 is within the bottom face protruded part 94.
- a state in double chain line changes to a state in solid line.
- the interfolded part described above is fused by the side face heater 16. More specifically, the electrically-heated wire 38 of the side face heater 16 is energized for heat generation, whereby the tubular member 37 reaches a high temperature, and then the handle 40 is moved to make the heater 16 contact with the bottom face protruded part 94, which is fused with the top face protruded part 93. Once fusing the bottom face protruded part 94 with the top face protruded part 93 by the side face heater 16, the interfolded part of the film 90 of the right side face 86 does not return to the original condition by force of restitution. The wrapping is completed in this way.
- the method in the embodiment simplifies the structure of the device because no necessity to hang up the CD case 80 to be wrapped after the CD case 80 is mounted on the mounting table 10. Further, the steps 18a, 19a, and 20 and the movable projections 11 and 12 fold and interfold the resin film 90 that is a wrapping material at its ends and at the parts corresponding to the sides of the CD case 80, so as to wrap precisely without failure with simple operation.

More specifically, the projections 111 of the upper movable portion 128 project downward and the projections 111 of the lower movable portion 129 project upward.

Abstract
Description
- The present invention relates to a wrapping device, and more particularly to a device for wrapping an object to be wrapped by wrapping a sheet such as a film therearound. The present invention also relates to a wrapping method, and more particularly to a method of wrapping an object to be wrapped by wrapping a film therearound.
- Various kinds of products are packaged by wrapping a sheet-like wrapping material such as a film therearound so as to protect their surface from being tainted or scratched. When an object to be wrapped is a product of cuboid shape, a so-called caramel wrapping is employed, whereby the object is wrapped in a film such that four faces of the cuboid object is wrapped in the film to protrude the film from the rest two faces, whereupon ends of the protruded film are folded back respectively.
- Such wrapping by only folding back would be fallen off the object, so the film is adhered at the ends or the folded part. - For the bond, adhesive bond is used, or the film itself is fused by heat to directly bond the film.
- Generally, a number of products of same shape are wrapped, so that a dedicated device performs the wrapping. For example, a product is wrapped by a wrapping device in a
patent document 1 described below. - Patent Document 1:
JP 8-276905 A - A conventional wrapping device such as the device described above performs a wrapping in large quantities automatically and as fast as possible, while the device is enlarged and complicated.
More specifically, it is necessary to turn an object to be wrapped or to wrap with a part supporting the object hung in the air so as to wrap a film around four faces of the object. That requires a turning mechanism or a mechanism for hanging up the object. Further, to fold back a part protruded from the rest two faces after wrapping the film around the four faces of the object, it is necessary to fold the ends of the film inward along edges of the object, thereby requiring a mechanism for precisely folding back. Still further, in the case that the object is of a thin plate such as a compact disk (CD) case, the protruded part is short, so that the part to be folded back is narrow, resulting in, especially, a precise and complicated structure of the mechanism for folding back. - When the film is transformed by folding or the like, it may return to its original shape by force of restitution. Consequently, in the case of wrapping by a wrapping device, maintaining the wrapping state requires bond by a fusion bond or the like, so the device is provided with a means for bond.
- In this way, a wrapping device in the known art is big, complicated, and expensive. That causes a problem of high cost per wrapping quantity in the case of small quantities of wrapping. Further, it is unable to install a big wrapping device to wrap in a small place such as an office not in a large place such as a factory.
- It is therefore an object of the present invention to provide an improved wrapping device for facilitating to wrap by a simpler structure.
- One of aspects of the present invention to solve the problems described above is to provide a wrapping device for wrapping an object to be wrapped of substantially cuboid shape with predetermined width, length, and thickness having top and bottom faces opposed in a thickness direction, front and rear end faces opposed in a longitudinal direction, and right and left side faces opposed in a width direction in a wrapping material being fusible by heating, including a mounting table for mounting the object, a movable folder, and a front face heater adapted to heat the wrapping material to such a temperature as fusible, the mounting table having a front bottom step, the movable folder having a front top step and being movable toward the mounting table, wherein the front top step is adapted to take its position facing to the front bottom step in the thickness direction when the movable folder is moved to the mounting table, in this state, the front face heater is movable between the front bottom step and the front top step, so as to fuse the wrapping material of the front end face.
- By the invention, it is easy to wrap the material around the four faces (the top and bottom faces, the front and rear end faces) of the object, and in this state, the ends of the material are mutually fused. More specifically, the material is wrapped to almost make a circuit around the top and bottom faces and the front and rear end faces with the opposite ends of the material at the front end face, whereupon a part protruded from the front end face is folded by the front top step and the front bottom step, and in this state, the front face heater is moved between the front top step and the front bottom step so as to fuse the material, thereby wrapping around the four faces of the object.
- Further, the device may include a side face interfolding member, and a side face heater adapted to heat the wrapping material to such a temperature as fusible, wherein the object on the mounting table is slidable in a sliding direction passing through the side face interfolding member, and wherein the wrapping material is interfoldable on at least one of the right and left side faces of the object when the object passes through the interfolding member, the side face heater being provided ahead of the interfolding member in the sliding direction.
- In such a structure, sliding the object to pass through the side face interfolding member interfolds the right and left side faces of the object, and further, the side face heater is provided ahead of the interfolding member in the sliding direction, so that keeping to slide the object enables to fuse the material interfolded at the right and left side faces.
- Still further, the wrapping device may have a structure wherein the mounting table includes a mounting face for mounting the object thereon, the mounting face being slanted relative to the horizontal, the object being slidable downward along the mounting face.
- In such a structure, the mounting face of the mounting table is provided as slanted relative to the horizontal so as to allow the object to slide downward along the mounting face, thereby enabling the object readily to slide.
- The wrapping device may also employ a lower movable portion adapted to support the object from the lower side, the lower movable portion being movable in the sliding direction of the object and urged upward.
- In such a structure, there is provided the lower movable portion adapted to support the object from the lower side and movable in the sliding direction of the object, so as to stabilize the sliding direction.
- Further, the lower movable portion may have a projection, wherein the projection is adapted to interfold the wrapping material protruded from the rear end face to at least one of the right and left side faces.
- In such a structure, the lower movable portion is provided with the projection, so as to support the object as interfolding the material protruded to the right and left side faces.
- Still further, the wrapping device may include an upper movable portion with a projection, wherein the projection is adapted to interfold the wrapping material protruded from the front end face to at least one of the right and left side faces.
- In such a structure, the upper movable portion is provided with the projection, so as to interfold the material protruded from the front end face to the right and left side faces.
- Further, the front face heater may be attached to the upper movable portion.
- In such a structure, the front face heater is attached to the upper movable portion, so as to provide a simplification of members.
- The side face interfolding member may also have rollers each with a conical surface, so that the wrapping material protruded from the top and bottom faces to at least one of the right and left side faces of the object is interfolded by the conical surfaces when the object is slid.
- In such a structure, the side face interfolding member is provided with the rollers each with the conical surface, by which surface the material protruded to the right and left side faces is interfolded and achieves a smooth interfolding.
- The side face interfolding member may have slots, which are slanted relative to the sliding direction of the object so that the wrapping material protruded from the top and bottom faces to at least one of the right and left side faces of the object is interfolded by being guided into the slots when the object is slid.
- In such a structure, the side face interfolding member is provided with the slots slanted relative to the sliding direction so that interfolding the material protruded from the top and bottom faces to the right and left side faces of the object by being guided into the slots achieves a smooth interfolding.
- The wrapping device may further include a side face heater adapted to heat the wrapping material to such a temperature as fusible below the side face interfolding member.
- In such a structure, there is provided the side face heater below the side face interfolding member, thereby enabling the object to be fused in sliding.
- The mounting table may also have a rear bottom step, so that a receptacle is formed between the front and the rear bottom steps of the table, a distance between the front and the rear bottom steps being substantially the same as the length of the object.
- In such a structure, there is provided the front bottom step and the rear bottom step, between which the receptacle is formed, so that mounting the material and the object on the receptacle folds the material protruded from the bottom face along the front and rear end faces.
- Another aspect of the present invention is to provide a wrapping device for wrapping an object to be wrapped of substantially cuboid shape with predetermined width, length, and thickness having top and bottom faces opposed in a thickness direction, front and rear end faces opposed in a longitudinal direction, and right and left side faces opposed in a width direction, in a wrapping material being fusible by heating, including a mounting table, first movable projections, a second movable projection, an interfolding portion arranged outside of the width direction of the mounting table, and a side face heater adapted to heat the wrapping material to such a temperature as fusible, wherein the mounting table has a mounting portion for mounting the object thereon, a width of which portion is substantially the same as that of the object, wherein the mounting table is movable up and down, so that the mounting portion is located upper than the top face of the interfolding portion at the upper position where the table is located upward, and so that the mounting portion is located lower than the top face of the interfolding portion at the lower position where the table is located downward, wherein the first projections are movable in the longitudinal direction along at least one of the right and left side faces of the object, so as to move to interfold the material protruded from the front and rear end faces toward the at least one of the side faces, wherein the second projection is movable in the thickness direction along the at least one of the side faces of the object, so as to move to interfold the material protruded from the top face toward the at least one of the side faces, and wherein the side face heater is movable toward the at least one of the side faces of the object mounted on the mounting table at the lower position.
- In this arrangement, after the material is wrapped around the four faces (the top and bottom faces and the front and rear end faces) of the object, interfolding the material protruded from the rest two faces (the right and left side faces) achieves an easy wrapping.
More specifically, the first projections are moved so as to interfold the material protruded from the front and rear end faces to the right and left side faces, and the second projection is moved so as to interfold the material protruded from the top face to the right and left side faces, and then the mounting table is moved from the upper position to the lower position so as to interfold the material protruded from the bottom face to the right and left side faces. Then the material is fused by the side face heater as the material interfolded. - The present aspect may further include a support, wherein the support is adapted to support the mounting table, thereby maintaining the upper position, the support having a knob, operation of the knob releasing supporting by the support, thereby allowing the mounting table to move to the lower position.
- In this arrangement, the mounting table is supported by the support, which has the knob to be operated to make the table move from the upper position to the lower position, and as a result of an easy operation for moving the table to the lower position.
- In the aspect, in the case of making the mounting table move downward to be at the lower position from the upper position so that the wrapping material protruded from the bottom face and located above the interfolding portion is interfolded by passing through the top face of the interfolding portion with the bottom face of the material mounted on the mounting portion slanted relative to the top face of the interfolding portion.
- In this arrangement, in the case of making the table move downward, since the material passes through the top face of the interfolding portion with the bottom face of the material mounted on the mounting portion slanted relative to the top face of the interfolding portion, the bottom of the material is gradually folded back from one side to the other, thereby enabling to be interfolded finely without fail.
- In the aspect, the second projection may have a flat end, so that in the case of making the second projection move to the mounting table, the end is slanted relative to the top edge of the side face of the object mounted on the mounting table when the end passes through the top edge.
- In this arrangement, since the second projection has the flat end, which is slanted relative to the top edge of the side face of the object mounted on the table when the end passes through the top edges, the top of the material is gradually folded back from one side to the other, thereby enabling to be interfolded finely without fail.
- In the aspect, the first projections may be formed at four places adjacent to opposite ends in the longitudinal direction of the right side face and the left side face of the object mounted on the mounting table and may have operating portions adapted to operate the first projections.
- In this arrangement, since the operating portion adapted to operate the first projections at four places is provided, the first projections are operated by operating the operating portion.
- Still further, the aspect may include a movable folder and a front face heater adapted to heat the wrapping material to such a temperature as fusible, wherein the mounting table has a front bottom step and a rear bottom step and forms a receptacle with substantially the same length as the object between the front and the rear bottom steps, and wherein the folder is provided with a front top step and movable toward the mounting table, so that the front top step is adapted to take its position facing to the front bottom step in the thickness direction when the movable folder is moved toward the mounting table, so that the front face heater is adapted to be displaced between the front bottom step and the front top step, thereby fusing the wrapping material of the front end face.
- In this arrangement, it is easy to wrap the material around the four faces (the top and bottom faces and the front and rear end faces) of the object, and in this state, the ends of the material are mutually fused. More specifically, the material is wrapped to almost make a circuit around the top and bottom faces and the front and rear end faces with the opposite ends of the material at the front end face, whereupon the front end face is folded by the front top step and the front bottom step, and in this state, the front face heater is moved between the front top step and the front bottom step so as to fuse the material, thereby wrapping around the four faces of the object.
- The aspect may also include a frame holding the second movable projection, the frame and the movable folder being pivotable, the mounting table being of rectangular shape, pivot axes of the frame and the folder being arranged out of one of the sides of the rectangular table and in parallel with the side.
- In this arrangement, the frame with the second projection and the movable folder are provided pivotable and have pivot axes at the same side relative to the table, so as to be easy to operate.
- Further, at least one of the front face heater and the side face heater may be constituted by an elastic material of cylindrical shape and a heating element embedded in the elastic material.
- In this arrangement, since the heaters are constituted by the elastic materials and the heating elements incorporated in the elastic materials, it enables entirely a firm attachment and a uniform heating when the wrapping material is heated.
- The present invention provides a wrapping method using the wrapping device described above, and may employ the method wherein the wrapping material has a width wider than that of the object to be wrapped, and a length more than twice the total amount of the length and thickness of the object, and including the steps of wrapping the material around the object to cover the top face, the rear end face, and the bottom face therewith, fusing the material by the front face heater with the front end face sealed with the front bottom step and the front top step, and fusing the material as interfolded at the right and left side faces.
- Such method enables a definite wrapping.
- Further, the present invention provides a wrapping method using the wrapping device described above, and may employ the method wherein the wrapping material has a width wider than that of the object to be wrapped, and a length more than twice the total amount of the length and thickness of the object, and including the steps of mounting the material on the mounting table to cover the receptacle therewith, with a first longitudinal end of the material on the front bottom step, folding the material under the bottom face of the object by the front bottom step and the rear bottom step after mounting the object on the material on the table so as to engage with the receptacle of the table, folding back the material to cover the top face of the object with a second longitudinal end of the material moved to the front bottom step, whereupon folding the second end by the front top step with the movable folder moved, and wrapping the top and bottom faces and the front and rear end faces of the object with the material by bonding the first end and the second end of the material by means of the front side heater.
- Such method enables a definite wrapping.
- The present invention provides a wrapping method using the wrapping device described above, and may employ the method wherein the wrapping material has a width wider than that of the object to be wrapped, and a length more than twice the total amount of the length and thickness of the object, and including the steps of bonding one longitudinal end and the other longitudinal end of the material so as to cover the top and bottom faces and the front and rear end faces of the object with the material, interfolding the edges in the longitudinal direction of the right and left side faces of the material inward by the first movable projections, interfolding a top in the thickness direction of the right and left side faces of the material inward by the second movable projection, interfolding a bottom in the thickness direction of the right and left side faces inward by moving the mounting table to the lower position, and bonding by the side face heaters.

Herein,wrapping devices - Fig. 1 shows the
wrapping device 1 provided in the first embodiment of the present invention. Thewrapping device 1 uses aresin film 90 as a wrapping material to wrap a rectangular compact disk case (viz. CD case) 80 as an object to be wrapped. Herein, theCD case 80 and theresin film 90 are shown in Fig. 10 and the like. Specifically, wrapping is done in such a way as placing theresin film 90 on a mounting table 10, mounting theCD case 80 thereon, folding thefilm 90, bonding one end of thefilm 90 and the other so as to cover the four faces of theCD case 80, interfolding thefilm 90 protruded from the rest two faces, and bonding thefilm 90.
Herein, in the description below, a thickness direction denotes a direction vertical to a surface of the mounting table 10, a width direction denotes a direction parallel to the surface of the table 10 and vertical to faces where thefilm 90 is interfolded, and a longitudinal direction denotes a direction vertical to both the thickness and the width directions. Further, as to faces of the object, a top face and a bottom face denote faces opposed to each other in the thickness direction, a front end face and a rear end face denote faces between two sides of the top and the bottom faces and opposed to each other in the longitudinal direction, and a right side face and a left side face denote faces between two sides of the top and the bottom faces and opposed to each other in the width direction. - The
wrapping device 1 includes the mounting table 10, firstmovable projections 11, secondmovable projections 12, amovable folder 17,interfolding portions 13, afront face heater 15,side face heaters 16, and a fixingplate 43. - The mounting table 10, as shown in Fig. 1, is of rectangular shape. The table 10 is provided with a
first rib 18 and asecond rib 19 projecting from the upper surface of the table 10. The first and thesecond ribs
Afront bottom step 18a is formed on the face nearer thesecond rib 19 of thefirst rib 18, and arear bottom step 19a is formed on the face nearer thefirst rib 18 of thesecond rib 19. The first and thesecond ribs receptacle 10a therebetween, which functions as a mounting portion for mounting a CD case described below.
Herein, the mounting table 10 has a width in conformity with that of theCD case 80, and a distance between thefront bottom step 18a of thefirst rib 18 and therear bottom step 19a of thesecond rib 19 is in conformity with the length of theCD case 80. Thereceptacle 10a seen from above is substantially the same shape as thebottom face 84 of theCD case 80. Further, the mounting table 10 has recessedareas 10b, which are located at opposite edges in the width direction of the table 10 to form a cavity between the table 10 and theinterfolding portions 13 described below so that a user can insert his or her fingers into the recessed areas to hang up the table 10. - The mounting table 10, as shown in Fig. 1, is supported by a pivot not shown and a
support 23. The pivot is connected with a connectingportion 50, which is secured to the fixingplate 43 provided under thewrapping device 1. The table 10 is pivotably supported around the pivot not shown, which direction is parallel to the width direction. - The
support 23 supports the table 10 to be at an upper position and at a lower position, that is, supports the table 10 with its position changed. Thesupport 23 has aknob 25, operation of which makes the table 10 supported at the upper position move to the lower position readily. Herein, a power of the operation uses a gravitational force of the table 10, whereas the table 10 is hung up by hands from the lower position to the upper position. - The table 10 pivots as described above, so that its slanted state changes, as being slanted such that the
rear bottom step 19a is higher than thefront bottom step 18a at the upper position, and as being the near-horizontal at the lower position. - The first
movable projections 11, as shown in Fig. 1, 10, and 11, are of reverse L-shaped plate. Thefirst projections 11 are provided at four places, adjacent to the opposite ends of the table 10 in the width direction, adjacent to the first and thesecond ribs first projections 11 in four places are situated little above the table 10 at almost the same position in the thickness direction (the vertical direction). - Distal ends 11a of the
first projections 11 project in the longitudinal direction. The distal ends 11a of a pair of the first projections on the same side in the width direction project in a different direction, facing to each other and inwardly.
Thefirst projections 11 are movable within almost the same length as the projecting length of thedistal ends 11a. - Fig. 2B shows the mounting table 10 seen from underneath. Referring to Fig. 2B, each pair of the
first projections 11 on the same side in the longitudinal direction (the cross direction) are mutually connected via acoupling rod 21. Thewrapping device 1 has twocoupling rods 21, with each of thefirst projections 11 in four places connected to one of therods 21. Thecoupling rods 21 each have a slidingportion 33 that engages with arail 31 at the bottom of the table 10 so as to be movable in the longitudinal direction. Consequently, movement of thecoupling rods 21 makes thefirst projections 11 move in the longitudinal direction.
Further, the slidingportions 33, as shown in Fig. 2B, are hung on therail 31 not to fall downward, and the members such as thecoupling rods 21 and thefirst projections 11 fixed on therods 21 are hung on the mounting table 10 via therails 31. - Further, the
wrapping device 1 has operatingportions 30 connected with thecoupling rods 21. Sliding the operatingportions 30 in the longitudinal direction makes thefirst projections 11 move. The operatingportions 30 each have arib 35 with theribs 35 of the two operatingportions 30 arranged facing to each other, between which aspring 34 is loaded. Thespring 34 is a compression spring and has urging force acting in a direction keeping away the two operatingportions 30 mutually, thereby keeping each other'soperating portions 30 away.
The two operatingportions 30 are arranged on the same left side of the table 10, so as to be operated in one hand. - Referring to Fig. 1, there is provided two pieces of the second
movable projections 12, which are of thin plate-like shape.
Further, thewrapping device 1 has aframe 22, to which two pieces of thesecond projections 12 are attached. Theframe 22 is journaled by apivot 22a attached to a connectingportion 50 and extending in the width direction. Theframe 22 is pivotable around thepivot 22a so as to be pivotally moved toward the table 10. Thesecond projections 12 are attached so that theirdistal ends 12a points toward the table 10. The distal ends 12a have substantially the same length as that of theCD case 80 in the longitudinal direction and are of substantially flat shape. Moving theframe 22 toward the table 10 makes thesecond projections 12 move from top down, thereby being outside of the table 10 in the width direction. - The
movable folder 17, as shown in Fig. 1, is a plate-like member and journaled by apivot 17a attached to the connectingportion 50 and extending in the width direction. Thefolder 17 is pivotable around thepivot 22a so as to be pivotally moved toward the table 10. The pivot point of thefolder 17 and the pivot point of theframe 22 with thesecond projections 12 are provided at the same side relative to the table 10. The pivot axes are situated outside of the side of the table 10 adjacent to the rib 18 (i.e., adjacent to the front end face 84 of the mounted CD case 80) and parallel to the side.
Further, thepivot 17a is connected to thefolder 17 adjacent to its one edge, whereas a fronttop step 20 is formed adjacent to the other edge on the side opposite to thepivot 17a.
Thefolder 17 is pivotally moved toward the table 10 around thepivot 22a. Pivotally moving thefolder 17 toward the table 10 displaces the fronttop step 20 to a point above thefront bottom step 18a on the table 10, so as to be opposed to thefront bottom step 18a in the thickness direction. - The
folder 17 has aslot 17b. It is constituted in such a manner that ahandle 40 described below attached to aretainer plate 39 of thefront face heater 15 passes through theslot 17b when thefolder 17 is moved toward the table 10. Consequently, such structure prevents thehandle 40 from contacting with thefolder 17 in the case of moving thefolder 17. - The
interfolding portions 13 are of elongated plate-like members and provided outside of the right and left sides of the table 10 in the width direction. Theinterfolding portions 13 in two places, as described below, are respectively located outside of aleft side face 85 and aright side face 86 of theCD case 80 mounted on the table 10. Theinterfolding portions 13 each have substantially the same length as that of thereceptacle 10a in the longitudinal direction.
Theinterfolding portions 13 each have atop face 13a, which is located at a lower level than thereceptacle 10a of the table 10 when the table 10 is at the upper position, and at a higher level than the table 10 at the lower position. Theinterfolding portions 13 are secured to the fixingplate 43. - In the process that the table 10 moves from the upper position to the lower position, the vertical position of the
receptacle 10a approximately corresponds to that of theinterfolding portions 13, and that is when the bottom surface of thereceptacle 10a of the table 10 is slanted relative to the top faces 13a of theinterfolding portions 13. More specifically, therear bottom step 19a is slanted higher relative to thefront bottom step 18a. - The
front face heater 15 is arranged at the side where thefolder 17 is provided relative to the table 10. In other words, thefront face heater 15 is located outside of the front end face 81 of theCD case 80 mounted on the table 10. Thefront face heater 15 is constituted, as a cross section of that is shown in Fig. 3, by atubular member 37 made of resin, rubber or the like of tubular shape having elasticity and an electrically-heated wire 38 which is a heating element embedded in thetubular member 37. Electrifying to the electrically-heated wire 38 generates heat in thewire 38, and the heat is conducted to thetubular member 37, thereby heating theresin film 90 contacting with thetubular member 37 to fuse thefilm 90 mutually, as described below. Herein, an adhesive being fusible by heating may be applied in advance on thefilm 90 that is a wrapping material to heat the adhesive for fusing. - The
front face heater 15 is retained by theretainer plate 39, which is of plate-like member. Thefront face heater 15 is attached to the edge of theretainer plate 39 to cover the entire area of the edge adjacent to the table 10 of theretainer plate 39.
Theretainer plate 39 is made of resin with heat resistance, so that the heat generated by the electrically-heated wire 38 is not easily conducted to theretainer plate 39. - Further, the
retainer plate 39 is movable in the width direction toward the table 10, and is urged in a direction away from the table 10 by an urging member not shown. Theretainer plate 39 has ahandle 40 secured thereto. Only when thehandle 40 is pushed toward the table 10, theheater 15 is moved toward the table 10, and when pushing is stopped, thehandle 40 moves back in a direction away from the table 10 by the urging member.
When thehandle 40 is pushed, thefront face heater 15 is located above thefront bottom step 18a and adjacent to the front end face 81 of theCD case 80 mounted on the table 10. Then, thefront face heater 15 is moved toward the table 10 to press the front end face 81 of theCD case 80.
In the state that thefolder 17 is moved toward the table 10, thefront face heater 15 is also movable toward the table 10. In this case, thefront face heater 15 is moved between thefront bottom step 18a and the fronttop step 20. - The
side face heaters 16 are arranged on either outside in the width direction of the table 10. Each of theside face heaters 16 is constituted, as a cross section of that is shown in Fig. 4, similar to thefront face heater 15.
Retainer plates 39 of theside face heaters 16 are located at a higher level than theinterfolding portions 13 and movable in the longitudinal direction toward the table 10. When being moved toward the table 10 at the lower position, theside face heaters 16 are moved toward the edges of either side of the table 10, and to a position above and adjacent to outside of the width direction of thereceptacle 10a. - Further, as well as the
front face heater 15, theside face heaters 16 are urged in a direction away from the table 10 by an urging member not shown. Theretainer plates 39 of theside face heaters 16 each are provided with ahandle 40. Only when thehandles 40 are pushed toward the table 10, theside face heaters 16 are moved toward the table 10.
In this way, theside face heaters 16 have the same movements to thefront face heater 15. - Now, a method for wrapping a
CD case 80 in aresin film 90 by using thewrapping device 1 will be described. - The
resin film 90 for use in wrapping has a width a little wider than that of theCD case 80 and a length more than twice the total amount of the length and thickness of theCD case 80. Herein, in the case of using a long film, it is to be cut in advance to the length described above.
A material of theresin film 90 is not limited, though a resin made of ethylene or polypropylene, a drawn film, or the like may be employed. - At first, as shown in Fig. 1, the mounting table 10 is located at the upper position and the
frame 22 and thefront face folder 17 are located away from the table 10. - Referring to the Fig. 5, the
resin film 90 is placed on the table 10. More specifically, an end of thefilm 90 in the longitudinal direction is to be adjacent to thefront bottom step 18a so as to cover the entire area of thereceptacle 10a therewith. Thefilm 90 is placed in this way, thereby covering thefront bottom step 18a and therear bottom step 19a.
A distance between the end of thefilm 90 in the longitudinal direction and thefront bottom step 18a is to be shorter than the thickness of theCD case 80. - Further, the CD case is mounted on the
film 90 to conform to thereceptacle 10a.
That ensures, as shown in Fig. 6, that thefilm 90 is placed between theCD case 80 and thefront bottom step 18a, so that thefilm 90 is folded along thefront bottom step 18a and toward the front end face 81 of theCD case 80. Similarly, thefilm 90 is placed between theCD case 80 and therear bottom step 19a, so that thefilm 90 is folded along therear bottom step 19a and toward the rear end face 82 of theCD case 80. Thebottom face 84 of theCD case 80 is covered with thefilm 90. - Next, the
resin film 90 is folded back to cover thetop face 83 of theCD case 80. Referring to Fig. 7, since the length of thefilm 90 is a little more than twice the total amount of the length and thickness of theCD case 80, its end covers thetop face 83 of theCD case 80. Thus, thefilm 90 covers therear end face 82, thetop face 83, and thebottom face 84, and the opposite ends of thefilm 90 in the longitudinal direction come to thefront end face 81.
Then, as shown in Fig. 7, themovable folder 17 is pivotally moved toward the table 10, thereby making the fronttop step 20 take its position facing to thefront bottom step 18a in the thickness direction.
The fronttop step 20 of thefolder 17 folds thefilm 90 protruded from thetop face 83 toward thefront end face 81, so that thefilm 90 partly overlaps as in the state shown in Figs. 8 and 9B.
At this time, slightly pulling thefilm 90 toward thefront end face 81 enables a more definite wrapping with thefilm 90 close to theCD case 80 without surface waviness. - In this state, the overlapped
film 90 is fused to be bonded by thefront face heater 15. More specifically, the electrically-heated wire 38 of thefront face heater 15 is energized for heat generation, whereby thetubular member 37 reaches a high temperature, and then thehandle 40 is moved in a direction indicated by arrows in Figs. 9A and 9B to bring thetubular member 37 in contact with the overlappedfilm 90, which becomes a high temperature and is fused. Once being fused, thefilm 90 does not return to the original condition by force of restitution even thefolder 17 is put back into place. - Therefore, as shown in Fig. 10, the
CD case 80 is covered with thefilm 90 at itsfront end face 81, itsrear end face 82, itstop face 83 and itsbottom face 84, whereas theleft side face 85 and theright side face 86 have thefilm 90 protruded therefrom in the width direction. - Further, as described below, the
film 90 protruded from the right and the left side faces 86 and 85 of theCD case 80 is interfolded. Herein, a method of interfolding at the right and the left side faces 86 and 85 will be described only about the case of theright side face 86, and as for the case of theleft side face 85, a description is omitted because of the similar case due to a symmetric shape. - Referring to Fig. 10, the table 10 is at the upper position, that is, the
receptacle 10a of the table 10 is located at a higher level than thetop face 13a of theinterfolding portion 13. Consequently, thefilm 90 protruded in the width direction is also located at a higher level than thetop face 13a of theinterfolding portion 13.
The distal ends 11a of thefirst projections 11 are located in front of and back of the protrudedfilm 90. - Then, as shown in Fig. 12, when the two operating
potions 30 are moved inward, thefirst projections 11 are moved inward, so that thefilm 90 protruded to theright side face 86 of theCD case 80 is pressed by the distal ends 11a to be folded inward. That leads to the state shown in Fig. 11. In the embodiment, since the two operatingportions 30 are adapted to be moved inward, all thefirst projections 11 are operated in one hand in such a manner as holding the operatingportions 30. Alternatively, only one operatingportion 30 may be equipped so as to operate all thefirst projections 11 by the oneoperating portion 30. - When the
first projections 11 are moved inward, a front end face protrudedpart 91 protruded from thefront end face 81 and a rear end face protrudedpart 92 protruded from the rear end face 82 among the protrudedfilm 90 are interfolded inward. Then, as shown in Fig. 11, a top face protrudedpart 93 protruded from thetop face 83 and a bottom face protrudedpart 94 protruded from thebottom face 84 are slightly transformed in a direction where the thickness direction extends, upon interfolding of the front end face protrudedpart 91 and the rear end face protrudedpart 92. - Further, pivotally moving the
frame 22 toward the table 10 leads through the state shown in Figs. 13 and 16 to Figs. 14, 15, and 17, thereby locating thesecond projection 12 adjacent to theright side face 86 of theCD case 80.
That is when, as shown in Fig. 13, the top face protrudedpart 93 is interfolded downward by thesecond projection 12. And when thesecond projection 12 is moved toward the table 10 and let downward, thedistal end 12a of thesecond projection 12 exceeds anupper side 86a of theright side face 86 of theCD case 80, being slanted. Thus, a point where the top face protrudedpart 93 is interfolded proceeds from a front side (the right as viewed in Fig. 13) to a rear side (the left as viewed in Fig. 13) gradually, thereby enabling a smooth interfolding with little catch. - After the top face protruded
part 93 is interfolded, theknob 25 of thesupport 23 is operated so as to move the table 10 from the upper position to the lower position. Referring to Fig. 14, when the table 10 is at the upper position before theknob 25 is operated, the bottom face protrudedpart 94 is located at higher level than thetop face 13a of theinterfolding portion 13, and then, when the table 10 is moved to the lower position, the bottom face protrudedpart 94 is interfolded upward, so the top face protrudedpart 93 is within the bottom face protrudedpart 94. In this manner, as shown in Fig. 20, a state in double chain line changes to a state in solid line. - When the table 10 is moved downward so as to be from the upper position to the lower position, faces of the table 10 in the vertical direction pass through the
top face 13a of theinterfolding portion 13. At this time, thebottom face 84 of theCD case 80 on the table 10 moves, being slanted relative to thetop face 13a of theinterfolding portion 13, so a point where the bottom face protruded part 97 is interfolded proceeds gradually from a front side (the right as viewed in Figs. 18 to 20) to a rear side (the left side as viewed in Figs. 18 to 20), thereby enabling a smooth interfolding with little catch. - Then, releasing the hand holding the operating
portions 30 to put thefirst projections 11 back into place and moving theframe 22 upward lead to a state shown in Fig. 19. In this state, since theinterfolding portion 13 holds the lower side of the bottom face protrudedpart 94, within which the front end face protrudedpart 91, the rear end face protrudedpart 92, and the top face protrudedpart 93 are, thefilm 90 does not restitute to return to the original condition before being interfolded. - Further, the interfolded part described above is fused by the
side face heater 16. More specifically, the electrically-heated wire 38 of theside face heater 16 is energized for heat generation, whereby thetubular member 37 reaches a high temperature, and then thehandle 40 is moved to make theheater 16 contact with the bottom face protrudedpart 94, which is fused with the top face protrudedpart 93.
Once fusing the bottom face protrudedpart 94 with the top face protrudedpart 93 by theside face heater 16, the interfolded part of thefilm 90 of theright side face 86 does not return to the original condition by force of restitution.
The wrapping is completed in this way. - The method in the embodiment simplifies the structure of the device because no necessity to hang up the
CD case 80 to be wrapped after theCD case 80 is mounted on the mounting table 10. Further, thesteps movable projections resin film 90 that is a wrapping material at its ends and at the parts corresponding to the sides of theCD case 80, so as to wrap precisely without failure with simple operation. - Now, another
wrapping device 2 provided in a second embodiment of the present invention will be described.
Figs. 22A and 22B are a front view and a side view of the wrapping device provided in the second embodiment of the present invention. Figs. 23 to 26 are enlarged side views of the upper part of Figs. 22A and 22B. Fig. 27 is a perspective view of a CD case to be wrapped and a resin film. Figs. 28 to 32 are perspective views and side views showing a diagram on the way of wrapping. - The
wrapping device 2, as shown in Fig. 22, includes a mounting table 110, amovable folder 117, right and left side face interfolding members (viz. side face interfolding members) 130, and heating rollers (viz. side face heaters) 133. - The mounting table has a
slope 137 with a mountingsurface 137a slanted relative to the horizontal, and an uppermovable portion 128 and a lowermovable portion 129 both being movable along the mountingsurface 137a of theslope 137. - The
slope 137 is of rectangular plate-like shape and substantially vertical to the horizontal. Theslope 137 is supported by asupport 138 provided underneath. There is provided afront bottom step 118a at an upper part and on the mountingsurface 137a of theslope 137. Referring to Fig. 22B, thefront bottom step 118a extends horizontally. - The upper and the lower
movable portion main body 142 in the shape of a rod extending horizontally andprojections 111 arranged to the opposite ends of themain body 142. Theprojections 111 project in a direction along the mountingsurface 137a of theslope 137 and inward so that theprojections 111 of the uppermovable portion 128 and theprojections 111 of the lowermovable portion 129 face to each other. More specifically, theprojections 111 of the uppermovable portion 128 project downward and theprojections 111 of the lowermovable portion 129 project upward.
Herein, themain body 142 has substantially the same length as the width of theCD case 80. A distance between the lowermovable portion 129 at a first stage and thefront bottom step 118a is substantially the same as the length of theCD case 80. - The upper and the lower
movable portions surface 137a of theslope 137. That is because theslope 137 hasgrooves 141 on the mountingsurface 137a thereof so thatprojections 135 formed on the upper and the lowermovable portions grooves 141, whereby preventing the upper and the lowermovable portions slope 137 and being movable along the mountingsurface 137a. Further, thegrooves 141 are arranged in a direction extending vertically, so that the upper and the lowermovable portions
Herein, the upper and the lowermovable portions movable portions movable portion 129 also has a stopper not shown so as to be located at the first stage. - The upper
movable portion 128 has ahandle 140, operation of which makes the uppermovable portion 128 move vertically by hand. There is also provided a heating portion (a front face heater) 143 on the lower part of the uppermovable portion 128 so as to fuse thefilm 90 of the front end face 81 of theCD case 80, as will be described below. - The
CD case 80 is mounted on the top of the lowermovable portion 129 of the mounting table 110 and on the mountingsurface 137a of theslope 137. - The right and left side
face interfolding members 130, as shown in Fig. 22 and 31, are located in two places at both sides slightly below midline of theslope 137. Each of theinterfolding members 130 in two places haveconical rollers shafts slope 137. Herein, theshafts surface 137a of theslope 137.
Therollers slope 137. - The
heating rollers 133 are positioned below theinterfolding members 130 in two places respectively and heated by heat generated by such as an electrical heater.
Theheating rollers 133 are rotatably secured by means ofshafts 133b secured to theslope 137. Herein, theshafts 133b are vertical to the mountingsurface 137a of theslope 137 and also vertical to a moving direction of the upper and the lowermovable portions CD case 80 is contactable withouter peripheries 133a of theheating rollers 133 at its right and left side faces 86 and 85. - Referring to Figs. 23, 24, and the like, the
movable folder 117 is of L-shaped plate and provided adjacent to the upper edge of theslope 137. Thefolder 117 is journaled by apivot 117a on theslope 137, so as to pivotally move toward the table 110. Thefolder 117 is provided with a fronttop step 120.
Herein, thefolder 117, as shown in Fig. 22A, has aslot 147 so that thehandle 140 of the uppermovable portion 128 is movable. - Pivotally moving the
folder 117 toward the table 110 makes the fronttop step 120 take its place facing to thefront bottom step 118a in the thickness direction, and it is possible to adjust a distance between the fronttop step 120 and thefront bottom step 118a at this state to be substantially the same as the thickness of theCD case 80. - Now, a method for wrapping a
CD case 80 in aresin film 90 by using thewrapping device 2 will be described.
At first, as shown in Fig. 27, theresin film 90 is placed to cover thetop face 83, therear end face 82, and thebottom face 84 therewith. Herein, theresin film 90 is of the same material and size as the case of thewrapping device 1 provided in the first embodiment, that is, has a width a little wider than that of theCD case 80 and a length more than twice the total amount of the length and thickness of theCD case 80. More specifically, thefilm 90 has a width adding a length for folding back at the opposite ends to the width of theCD case 80 and the length adding an overlap space to the length twice the total amount of the length and thickness of theCD case 80. - In this state, the
CD case 80 with thefilm 90 is mounted on the top of the lowermovable portion 129 of the mounting table 110 and on the mountingsurface 137a of theslope 137 of thedevice 2. Herein, at this time, themovable folder 117 is open, as shown in Fig. 23. - Fig. 28 shows the
film 90 in this state. In such a manner, the rear end face 82 of theCD case 80 contacts with the lowermovable portion 129, and the rear end face protrudedpart 92 of thefilm 90 is interfolded since theprojections 111 of the lowermovable portion 129 project upward. - Further, the
film 90 at thebottom face 84 is sandwiched between the mountingsurface 137a of theslope 137 and theCD case 80. The upper edge of the resin film at thebottom face 84 is folded toward the front end face 81 by thefront bottom step 118a. - Next, the
folder 117 is pivotally moved toward the table 110, and this state is shown in Figs 24 and 29. The fronttop step 120 takes its place facing to thefront bottom step 118a in the thickness direction, thereby folding thefilm 90 at thetop face 83 toward thefront end face 81.
In such a manner, portions of thefilm 90 under thebottom face 84 and on thetop face 83 are folded to be along thefront end face 81, thereby covering the front end face 81 of theCD case 80. Thefilm 90 at thefront end face 81 is partly overlapped. - Further, moving the
handle 140 downward makes the uppermovable portion 128 move downward. Therefore, as shown in Fig. 25, the bottom side of themain body 142 of the uppermovable portion 128 contacts with the front end face 81 of theCD case 80, and then, theheating portion 143 of the uppermovable portion 128 heats to fuse the overlappingfilm 90 interfolded toward thefront end face 81. - Then, as shown in Fig. 30, the
film 90 covers thetop face 83, therear end face 82, thebottom face 84, and the front end face 81 therewith. Each of the right and the left side faces 86 and 85 have a top face protrudedpart 93 and a bottom face protrudedpart 94 where thefilm 90 is protruded. The front end face protrudedpart 91 and the rear end face protrudedpart 92 are folded back by theprojections 111 on the upper and the lowermovable portions - If and when the
handle 140 is moved further downward by a stronger force than the upward urging force acting on the upper and the lowermovable portions movable portion 128, theCD case 80, and the lowermovable portion 129 are also moved downward. Therefore, the right and the left side faces 86 and 85 of theCD case 80 is led adjacent to the right and leftside interfolding members 130 situated at both sides slightly below the midline of theslope 137.
In such a manner, theCD case 80 slides in the same direction as the moving direction of the upper and the lowermovable portions surface 137a. - Referring to Fig. 31, one of the bottom face protruded
parts 94 is interfolded inward by aconical surface 131 a of theroller 131 of theinterfolding member 130, and one of the top face protrudedparts 93 is interfolded inward by aconical surface 132a of theroller 132.
Consequently, when theCD case 80 pass through theinterfolding member 130, the top face protrudedpart 93 and the bottom face protrudedpart 94 are interfolded with overlapped so that the top face protrudedpart 93 comes outside. Further, such interfolding is done from downside to upside. - Referring to Fig. 32, it follows with the
heating roller 133 passing through the overlapped part, so that theouter periphery 133a of theheating roller 133 contact with the top face protrudedpart 93. The top face protrudedpart 93 and the bottom face protrudedpart 94 are heated to be fused. Herein, theheating roller 133 is arranged just below theinterfolding member 130, thereby fusing thefilm 90 before thefilm 90 is put back into place by a rebound. - The front end face 81 of the
CD case 80 passes through theheating roller 133, theCD case 80 is moved to a lower level than theheating roller 133, and then the wrapping of theCD case 80 is completed.
Herein, Figs. 28 to 32 illustrate only theleft side face 85, though the wrapping of theright side face 86 is also done likewise simultaneously. - Now, still another
wrapping device 3 provided in a third embodiment of the present invention will be described.
Fig. 33 is a front view and a side view of the wrapping device provided in the third embodiment of the present invention. Fig. 34 is a perspective view of one of right and left side face interfolding members. Figs. 35 and 39 are perspective view on the way of wrapping. Figs. 36 to 38 are perspective views and side views showing diagrams on the way of wrapping. - The
wrapping device 3, as shown in Fig. 33, includes a mounting table 110, amovable folder 117, right and left side face interfolding members (viz. side face interfolding members) 160, andheating rollers 133. Thewrapping device 3 is different only in a structure of the right and left sideface interfolding members 160 from thewrapping device 2 described above. - Each of the
interfolding members 160 provided in thedevice 3, as shown in Fig. 34, is a rectangular tube having rectangular inner and outer shapes with twoslots interfolding members 160 are respectively arranged at both ends of and slightly below the midline of theslope 137, similarly to theinterfolding members 130 provided in the second embodiment. Further, theinterfolding members 160 are positioned with their slot faces 163 having theslots - As to each of the
interfolding members 160, theslots slot 161 extends from afirst edge 165 to asecond edge 166 in a longitudinal direction and theother slot 162 extends from thefirst edge 165 to about the halfway in the longitudinal direction.
Referring to Fig. 33, theslot 161 is arranged closer to the mountingsurface 137a of the table 110 of theslope 137 than theslot 162. - The
slot 161 extends substantially parallel to the sliding direction of theCD case 80 that is the longitudinal direction from thefirst edge 165 to about the halfway, and is slanted relative to the sliding direction so as to keep away from theslope 137 from about the halfway to thesecond edge 166. Theslot 162 is slanted relative to the sliding direction so as to come close to theslope 137 from thefirst edge 165 to about the halfway.
The position of theslot 161 at thefirst edge 165 in a thickness direction is adjacent to the mountingsurface 137a, whereas the position of theslot 162 at thefirst edge 165 is at the thickness of theCD case 80 away from about thesurface 137 of theslope 137 in the thickness direction. - Now, a method for wrapping a
CD case 80 in aresin film 90 by using thewrapping device 3 will be described.
Similar to the case of the second embodiment, as shown in Fig. 27, theresin film 90 is placed to cover thetop face 83, therear end face 82, and thebottom face 84 therewith. Then theCD case 80 is wrapped by the method described in the second embodiment, until thefilm 90 at the side of thefront end face 81 is fused to cover thetop face 83, therear end face 82, thebottom face 84, and the front end face 81 therewith.
A method of interfolding thefilm 90 protruded toward the right and left side faces 86 and 85 is as follows. It is different from the method described in the second embodiment. - Specifically, the upper
movable portion 128 is moved downward by means of thehandle 40, and theCD case 80 and the lowermovable portion 129 are moved downward. Therefore, the top face protrudedparts 93 and the bottom face protrudedparts 94, each of which are thefilm 90 protruded from the right and the left side faces 86 and 85, come adjacent to the right and left sideface interfolding members 160 respectively. - Further downward movement of the
CD case 80 changes a state shown in Fig. 35 into a state shown in Fig. 36, that is, the bottom face protrudedpart 94 is guided into theslot 161 of theinterfolding member 160 and the top face protrudedpart 93 is guided into theslot 162. - Referring to Fig. 36B that shows a cross section adjacent to the lower edge of the
CD case 80, the bottom face and the top face protrudedparts slots - Moving the
CD case 80 still further downward, the bottom face protrudedpart 94 goes into and along theslot 161, whereas the top face protrudedpart 93 goes into and along theslot 162. Since theslot 162 is slanted in the direction closer to theslope 137, the top face protrudedpart 93 is gradually folded toward theslope 137 in accordance with the move of theCD case 80.
Then, when the lower edge of theCD case 80 comes adjacent to the halfway of theinterfolding member 160, as shown in Figs 37A and 37B, the top face protrudedpart 93 is completely interfolded. The bottom face protrudedpart 94 is not interfolded at about the halfway. - Moving the
CD case 80 successively downward, the bottom face protruded part goes into along theslot 161. Since theslot 161 is slanted away from theslope 137, the bottom face protrudedpart 94 is gradually folded toward the opposite side of theslope 137 in accordance with the move of theCD case 80. - When the
entire CD case 80 passes through theinterfolding member 160, as shown in Fig. 39, thefilm 90 at theleft side face 85 of theCD case 80 is completely interfolded. - Then, as the
device 2 described above, the overlapping part of the top face and the bottom face protrudedparts heating roller 133, and theouter periphery 133a of theheating roller 133 contacts with the top face protrudedpart 93. Therefore, the top face and the bottom face protrudedparts heating roller 133 is arranged just below theinterfolding member 160, thereby fusing thefilm 90 before that thefilm 90 is put back into place by a rebound. - Use of the
wrapping devices CD case 80 to be wrapped in theresin film 90 that is a wrapping material with a simple operation. More specifically, theCD case 80 is wrapped in thefilm 90 and set in thedevices movable folder 117 is pivotally moved, and thehandle 140 is moved downward, thereby enabling a completion of wrapping. Consequently, it is available to wrap without a complicated operation and readily by anyone. - In the embodiments, an object to be wrapped is the
CD case 80, but may be any other object to be wrapped. Further, a wrapping material is theresin film 90, but may be any other wrapping material.
