Definitions
- This invention relates to a wrapping device and more particularly to a device for wrapping rolls to cover their ends as well as their sides.
- a wrapping paper is wound with its ends slightly projected from the ends of the rolls and this projected cylindrical portion of the wrapping paper is tucked gradually towards the centre of the ends of the roll as the roll is rotated and a separate circular piece of wrapping paper is pasted thereon (U.S. Patent No. 2,368,213).
- a wrapping paper is wound with its ends projected by at least a length equal to the radius of the roll, then the projected wrapping paper is twisted by rotating the roll and pushed into the hole at the centre of the roll.
- the former method produces a good appearance because the ends of the roll are covered with a circular piece of wrapping paper.
- it has a fault in that the process of pasting on the circular piece of wrapping paper is troublesome and that it closes up the centre hole of the roll, making it inconvenient to transport.
- the latter method is simpler in its process than the former. However, it may impair the quality and appearance of the roll by the formation of irregular wrinkles on the wrapped ends. Therefore, it is used mainly for rolls of small diameter.
- the inventor previously proposed a first method of wrapping about a roll a paper pre-processed to have folds in the portions destined to extend cylindrically from the ends of the roll and then winding the folded portion and tucking it into the centre of the roll (Japanese Patent Disclosure No. 13984/77), and a second method wherein tucking members are positioned at equal spaces on the periphery at the ends of the rolls, the cylindrical portions of wrapped paper extending from the ends of the rolls are depressed towards the centre of the roll so that ridge portions are formed, whereafter the centre portion of the wrapping paper is pushed into the centre of the rolls and the ridge portions are laid in a fixed direction (Japanese Patent Disclosure No. 70691/77).
- U.S. Patent No. 2,066,414 provides a device for wrapping cylindrical containers or articles in which folds are formed in a cylindrical extension of wrapping material which extends beyond the ends of the article.
- This device includes at a single station a plurality of circumferentially spaced tucking members (153) and a plurality of internal projecting members (164), which cooperate with each other to provide alternate grooves and ridges in the extension.
- tucking members 153
- internal projecting members 164
- a plurality of radially movable internal projecting members (13) are provided in association with said tucking members (4) to assure correct ridge and groove formation and in that said projecting members and said plug means are disposed on a common axial shaft (11), said shaft being moved axially from a first operational position in which said projecting members contact the inner surface of the extension, to a second operational position in which said projecting members and said plug are clear of said extension and subsequently to a third operational position wherein said plug causes said portion of said extension to enter the axial bore.
- the device according to the present invention can wrap the ends of the roll neatly by producing even folds and prevent the central hole of the roll from being blocked. Accordingly, the present device is suitable particularly for a roll of large diameter.
- a roll 1 to be wrapped is rotated by rollers 3 (rotation and support mechanisms not shown) to have several wrappings of a wrapping paper 2 wound thereon so as to project from the ends of the roll 1. Consequently, the end portion 2' of the wrapping paper projects cylindrically from both ends of the roll 1.
- the length of the projected wrapping paper 2' should be slightly larger than the radius of the roll.
- a device for wrapping that end of the roll At either end of the roll 1, there is provided a device for wrapping that end of the roll.
- the device is mounted on a frame 9 and is adjusted to a prescribed distance from the end of the roll by moving the frame 9 supported by wheels 22 along a rail 23.
- a cylindrical frame 21 having a slightly larger diameter than that of the roll to be wrapped is provided on the frame 9.
- the cylindrical frame 21 has a number of tucking members 4 for tucking in the projected portion of the wrapping paper 2' placed at equal intervals about the circumference thereof.
- a fulcrum supporting shaft 6 for each tucking member 4 is supported by a bearing 5 fixed on the side of the cylindrical frame 21.
- the fulcrum supporting shafts 6 of the tucking members are connected by flexible joints 7 in a generally circular pattern ( Figure 2).
- An arm 10 is projected from the fulcrum supporting shaft of the topmost fulcrum supporting shaft 6, and a fluid pressure cylinder 8 is connected to the arm 10. Therefore, the operation of the fluid pressure cylinder 8 causes the tips of the tucking members 4 to turn simultaneously towards the center of the cylindrical frame round the fulcrum supporting shaft 6.
- a plug 14 having substantially the same diameter as that of the hole 1' projects from the frame 9, and the plug 14 is given an axial movement and slow rotational motion through a shaft 11.
- the shaft 11 of the plug 14 has a sliding base 12 and a fixed ring 19 fitted thereon.
- the sliding base 12 has pivotally attached thereto a number of radially extending main arms 16 equal to the number of tucking members 4.
- each main arm 16 is provided with a rotary piece 17 having welded thereon a projecting member 13 and the main arm 16, the rotary piece 17, an arm 18 and an arm 20 form a parallelogram.
- the lower end of the arm 20 is pivotally attached to the fixed ring 19. Therefore, when the sliding base 12 is caused to advance on the shaft 11 by rotation of driving screws 24', the link mechanism of the projecting members 13 all expand radially at one time and the tips 13' of the projecting members are placed between the tucking members 4. Then if the sliding base 12 is caused to retract by reverse rotation of the driving screws 24', the main arm 16 and the projecting members 13 are brought more parallel to the shaft 11, that is they are brought into a folded state.
- the driving screw 24' is rotated by a motor (not shown) in a box 24.
- the frame 9 is moved so as to position the fulcrum supporting shafts 6 of tucking members 4 near the end of the roll 1 which has been wound on its periphery with wrapping paper 2 by the roller 3 ( Figure 3(A)).
- the cylinder 8 When the fulcrum supporting shafts 6 are positioned near the end of the roll 1, the cylinder 8 is operated to turn all the tucking members 4 inward at the same time and the sliding base 12 is advanced to cause the projecting members 13 to rise and bring the tips 13' into contact with the inside of the cylinder of wrapping paper 2' projecting from the end of the roll 1.
- the tucking members 4 contact the periphery of the cylinder of wrapping paper 2' projecting from the end of the roll 1 from the outside to produce groove portions, while the projecting members 13 contact the cylinder of wrapping paper from the inside at points lying between the tucking members to produce ridge portions ( Figure 3(B)).
- the tucking members 4 are caused to turn inward by further operation of the cylinder 8. Then, the sliding base 12 is caused to draw back so as to pucker up the projecting members 13. The operation of the projecting members is slightly delayed so that the cylinder of wrapping paper is always formed into grooves by the tucking members and into ridges by the projecting members.
- the , tucking members can be of rod or plate shape and can be made of plastic, wood or metal. They are of a length equal to, or somewhat less than, the thickness of the paper on the roll (from the surface to the center hole). When the structure shown in Figure 5- Figure 7 is used, the folds will be finished more neatly on the ends of the roll.
- projecting rails 26 are provided on the both sides of a bar member 25 having a fin, and triangular plates 27 are slidably inserted into the projecting rails 26.
- a cylinder 29 is fixed on the bar member 25 and connected with triangular plates 27 through a bracket 28.
- an elastic wire 30 is supported by a shaft 33 and rotated by a cylinder 31 placed at the tip of the bar member 25.
- a flexible piece 34 is provided on the tip of the tucking members as shown in Figure 9.
- This piece 34 is normally held in extended state by means of a spring 35, and when the wrapping paper is pushed in by the plug 14, it is caused to bend into the hollow hole under the force of the plug 14. Through this action the piece 34 protects the edge of the hole and also makes the folds neat.
- the projecting members 13 are made of a highly flexible wire material because the wrapping paper may be broken if the motions of the tucking members and the projecting members 13 are not smoothly coordinated.
- the material of these pieces can be metal, plastic, wood, bamboo, etc.
- the most appropriate relationship between the motions of the tucking and projecting members can be obtained by experiments and calculations, and it is preferable to control the hydraulic cylinder- actuating motor so that the tucking and projecting members can work in accordance with such relationship.
- the device for wrapping the ends of rolls according to this invention folds the cylinder of wrapping paper projecting from the ends of the roll by supporting the cylinder from both the inside and the outside and thus is able to wrap the ends in neat folds. It is especially suitable for wrapping rolls having a larger diameter.

Description
- This invention relates to a wrapping device and more particularly to a device for wrapping rolls to cover their ends as well as their sides.
- There have hitherto been known several methods for wrapping the ends of rolls. In one method a wrapping paper is wound with its ends slightly projected from the ends of the rolls and this projected cylindrical portion of the wrapping paper is tucked gradually towards the centre of the ends of the roll as the roll is rotated and a separate circular piece of wrapping paper is pasted thereon (U.S. Patent No. 2,368,213). In another method a wrapping paper is wound with its ends projected by at least a length equal to the radius of the roll, then the projected wrapping paper is twisted by rotating the roll and pushed into the hole at the centre of the roll.
- The former method produces a good appearance because the ends of the roll are covered with a circular piece of wrapping paper. However, it has a fault in that the process of pasting on the circular piece of wrapping paper is troublesome and that it closes up the centre hole of the roll, making it inconvenient to transport.
- The latter method is simpler in its process than the former. However, it may impair the quality and appearance of the roll by the formation of irregular wrinkles on the wrapped ends. Therefore, it is used mainly for rolls of small diameter.
- As methods for overcoming the defect of the latter method, the inventor previously proposed a first method of wrapping about a roll a paper pre-processed to have folds in the portions destined to extend cylindrically from the ends of the roll and then winding the folded portion and tucking it into the centre of the roll (Japanese Patent Disclosure No. 13984/77), and a second method wherein tucking members are positioned at equal spaces on the periphery at the ends of the rolls, the cylindrical portions of wrapped paper extending from the ends of the rolls are depressed towards the centre of the roll so that ridge portions are formed, whereafter the centre portion of the wrapping paper is pushed into the centre of the rolls and the ridge portions are laid in a fixed direction (Japanese Patent Disclosure No. 70691/77).
- These methods proposed by the inventor have some defects in that the pitch of the folds on the wrapping paper have to be changed as the diameter of the roll to be wrapped is altered, or that the projected cylindrical portion of the wrapping paper cannot always be folded evenly with the tucking members because the projected portion does not always maintain a perfectly circular shape.
- In a further disclosure U.S. Patent No. 2,066,414 provides a device for wrapping cylindrical containers or articles in which folds are formed in a cylindrical extension of wrapping material which extends beyond the ends of the article. This device includes at a single station a plurality of circumferentially spaced tucking members (153) and a plurality of internal projecting members (164), which cooperate with each other to provide alternate grooves and ridges in the extension. By means of relative rotation between the roll and the tucking members the ridges are caused to overlie the grooves and the ridges are pressed against the roll end by the tucking members.
- According to one aspect of the invention there is provided a device for wrapping an end of a roll having an axial bore (1') in a wrapping material (2) which material has been wrapped about the roll to form a cylindrical extension of a length approximating to the radius of the roll of said material extending from the end of said roll; which comprises a combination at a single station of:
- a) a plurality of circumferentially spaced tucking members (4), said tucking members being co-operable to provide alternate grooves and ridges in said extension,
- b) means (3) for providing a partial rotation of said roll to cause said ridges to overlie said grooves while said tucking members (4) press the ridged and grooved extension against the roll end, and
- c) plug means (14) for causing a portion of said extension to enter and be retained in said axial bore; characterised in that a plurality of radially movable internal projecting members (13) are provided in association with said tucking members (4) to assure correct ridge and groove formation, and said projecting members and said plug means are disposed on a common axial shaft (11), said shaft being movable axially from a first operational porision in which said projecting members contact the inner surface of the extension, to a second operational position in which said projecting members and said plug are clear of said extension and subsequently to a third operational position wherein said plug causes said portion of said extension to enter the axial bore.
- According to a second aspect of the invention there is provided a method for wrapping an end of a roll having an axial bore (1') in a wrapping material (2) which material has been wrapped about the roll to form a cylindrical extension of a length approximating to the radius of the roll of said material extending from the end of said roll; which comprises effecting the following steps at a single station:
- a) causing a plurality of circumferentially spaced tucking members (4) to provide alternate ridges and grooves in said extension,
- b) partially rotating said roll against said tucking members (4) to cause said ridges to overlie said grooves, and
- c) forcing a plug means (14) into the axial bore of the roll thereby folding a portion of said extension into the axial bore thereby to retain the same,
- characterized in that a plurality of radially movable internal projecting members (13) are provided in association with said tucking members (4) to assure correct ridge and groove formation and in that said projecting members and said plug means are disposed on a common axial shaft (11), said shaft being moved axially from a first operational position in which said projecting members contact the inner surface of the extension, to a second operational position in which said projecting members and said plug are clear of said extension and subsequently to a third operational position wherein said plug causes said portion of said extension to enter the axial bore.
- Since the cylindrically extending wrapping paper is tucked on the ends of the roll in a state wherein the inner and outer peripheral surfaces thereof are strainedly supported, the device according to the present invention can wrap the ends of the roll neatly by producing even folds and prevent the central hole of the roll from being blocked. Accordingly, the present device is suitable particularly for a roll of large diameter.
- Various ways of carrying out the invention are described in detail below with reference to drawings, in which:
- Figure 1 is a front view, partially in cross section, of a device for wrapping the ends of rolls according to this invention,
- Figure 2 is a sectional view of the device in Figure 1 along a line II-II thereof.

- Figures 8(A)-8(C) the state of tucking when the tucking members in Figure 5 are used.
- Figure 9 is an explanatory view showing another example of the device for wrapping the ends of rolls by this invention.
- Figure 1 shows one embodiment of the device for wrapping the ends of rolls according to this invention.
- At first, a
roll 1 to be wrapped is rotated by rollers 3 (rotation and support mechanisms not shown) to have several wrappings of awrapping paper 2 wound thereon so as to project from the ends of theroll 1. Consequently, theend portion 2' of the wrapping paper projects cylindrically from both ends of theroll 1. The length of the projectedwrapping paper 2' should be slightly larger than the radius of the roll. - At either end of the
roll 1, there is provided a device for wrapping that end of the roll. As the devices are identical only one of them will be described. The device is mounted on aframe 9 and is adjusted to a prescribed distance from the end of the roll by moving theframe 9 supported bywheels 22 along arail 23. Acylindrical frame 21 having a slightly larger diameter than that of the roll to be wrapped is provided on theframe 9. Thecylindrical frame 21 has a number of tuckingmembers 4 for tucking in the projected portion of thewrapping paper 2' placed at equal intervals about the circumference thereof. Afulcrum supporting shaft 6 for each tuckingmember 4 is supported by a bearing 5 fixed on the side of thecylindrical frame 21. Thefulcrum supporting shafts 6 of the tucking members are connected byflexible joints 7 in a generally circular pattern (Figure 2). - An
arm 10 is projected from the fulcrum supporting shaft of the topmostfulcrum supporting shaft 6, and afluid pressure cylinder 8 is connected to thearm 10. Therefore, the operation of thefluid pressure cylinder 8 causes the tips of the tuckingmembers 4 to turn simultaneously towards the center of the cylindrical frame round thefulcrum supporting shaft 6. - At the position corresponding to the center hole of the
roll 1, aplug 14 having substantially the same diameter as that of the hole 1' projects from theframe 9, and theplug 14 is given an axial movement and slow rotational motion through ashaft 11. Theshaft 11 of theplug 14 has asliding base 12 and a fixedring 19 fitted thereon. Thesliding base 12 has pivotally attached thereto a number of radially extendingmain arms 16 equal to the number of tuckingmembers 4. - The tip of each
main arm 16 is provided with arotary piece 17 having welded thereon a projectingmember 13 and themain arm 16, therotary piece 17, anarm 18 and anarm 20 form a parallelogram. The lower end of thearm 20 is pivotally attached to the fixedring 19. Therefore, when thesliding base 12 is caused to advance on theshaft 11 by rotation of driving screws 24', the link mechanism of the projectingmembers 13 all expand radially at one time and the tips 13' of the projecting members are placed between thetucking members 4. Then if thesliding base 12 is caused to retract by reverse rotation of the driving screws 24', themain arm 16 and the projectingmembers 13 are brought more parallel to theshaft 11, that is they are brought into a folded state. The driving screw 24' is rotated by a motor (not shown) in abox 24. - In the device for wrapping the ends of rolls, the
frame 9 is moved so as to position thefulcrum supporting shafts 6 of tuckingmembers 4 near the end of theroll 1 which has been wound on its periphery with wrappingpaper 2 by the roller 3 (Figure 3(A)). - When the
fulcrum supporting shafts 6 are positioned near the end of theroll 1, thecylinder 8 is operated to turn all thetucking members 4 inward at the same time and thesliding base 12 is advanced to cause the projectingmembers 13 to rise and bring the tips 13' into contact with the inside of the cylinder of wrappingpaper 2' projecting from the end of theroll 1. - Therefore, the
tucking members 4 contact the periphery of the cylinder of wrappingpaper 2' projecting from the end of theroll 1 from the outside to produce groove portions, while the projectingmembers 13 contact the cylinder of wrapping paper from the inside at points lying between the tucking members to produce ridge portions (Figure 3(B)). - Once the cylinder of wrapping
paper 2' has been contacted from both the outside and inside, thetucking members 4 are caused to turn inward by further operation of thecylinder 8. Then, thesliding base 12 is caused to draw back so as to pucker up the projectingmembers 13. The operation of the projecting members is slightly delayed so that the cylinder of wrapping paper is always formed into grooves by the tucking members and into ridges by the projecting members. - Just before, the
tucking members 4 contact the end of the roll (Figure 3(C)), acylinder 15 for drawing back theshaft 11 together with thesliding base 12 is put into operation and the projectingmembers 13 and theplug 14 are withdrawn from the cylinder of wrappingpaper 2' (Figure 3(D)). Therefore, only thetucking members 4 remain in pressing contact with the end of the roll and the ridges are maintained in the wrapping paper (see the right end of Figure 1). Theroll 1 is then rotated slightly so that the tucking members fold over the ridges and cause them to lie flat in one direction (Figure 4). Then thecylinder 15 is operated to cause the part of the folded wrapping paper which faces the hole 1' to be pushed into the hole by theplug 14 and thus complete the wrapping of the roll. The , tucking members can be of rod or plate shape and can be made of plastic, wood or metal. They are of a length equal to, or somewhat less than, the thickness of the paper on the roll (from the surface to the center hole). When the structure shown in Figure 5-Figure 7 is used, the folds will be finished more neatly on the ends of the roll. - Referring to Figures 5 to 7, projecting
rails 26 are provided on the both sides of abar member 25 having a fin, andtriangular plates 27 are slidably inserted into the projecting rails 26. For controlling the sliding motion of thetriangular plates 27, acylinder 29 is fixed on thebar member 25 and connected withtriangular plates 27 through abracket 28. - At the top of the
bar member 25, anelastic wire 30 is supported by ashaft 33 and rotated by acylinder 31 placed at the tip of thebar member 25. - When using tucking members as mentioned above, a
lever 32 is rotated bycylinder 31 aboutshaft 33 and a supportingshaft 6 is rotated by a cylinder (not shown) after the tip of thewire 30 contacts with the end of theroll 1. At the same time, the projectingmembers 13 in contact with the inside of the cylinder of wrappingpaper 2' are puckered up gradually by drawing back the slidingbase 12. Thus, at the end of the cylinder of wrapping paper, ridge and groove portions are formed as shown in Figure 8(A). When the tucking members are further turned and the projectingmembers 13 are withdrawn from the wrapping paper, the tucking members remain in close contact with the end of the roll with the ridge portions maintained as shown in Figure 8(B). At this time, thewire 30 is drawn into a groove provided at the bottom of thebar member 25. Appropriate gaps are left between the tucking members in close contact with end of the roll. Therefore, when thecylinder 29 is operated, thetriangular plates 27 on both sides of thebar member 25 are caused to slide towards the center along the projectingrail 26 to eliminate the gaps betweentriangular plates 27 and raise the ridges (Figure 8(C)). In such a state, theroll 1 is rotated and the ridges are laid towards the periphery. Thereafter, the end of the wrapping paper is pushed into the hole 1' by theplug 14. - Further, a
flexible piece 34 is provided on the tip of the tucking members as shown in Figure 9. Thispiece 34 is normally held in extended state by means of aspring 35, and when the wrapping paper is pushed in by theplug 14, it is caused to bend into the hollow hole under the force of theplug 14. Through this action thepiece 34 protects the edge of the hole and also makes the folds neat. - The projecting
members 13 are made of a highly flexible wire material because the wrapping paper may be broken if the motions of the tucking members and the projectingmembers 13 are not smoothly coordinated. The material of these pieces can be metal, plastic, wood, bamboo, etc. - In case of an actual operation, the most appropriate relationship between the motions of the tucking and projecting members can be obtained by experiments and calculations, and it is preferable to control the hydraulic cylinder- actuating motor so that the tucking and projecting members can work in accordance with such relationship.
- The device for wrapping the ends of rolls according to this invention, as explained above, folds the cylinder of wrapping paper projecting from the ends of the roll by supporting the cylinder from both the inside and the outside and thus is able to wrap the ends in neat folds. It is especially suitable for wrapping rolls having a larger diameter.
