Disclosure of Invention
Problems to be solved by the invention
When a plurality of sticks are to be stored in a standing state in a packaging bag, it is preferable to feed the sticks into the packaging bag so that the posture of the sticks does not deviate in the packaging bag. If the posture of each stick in the packaging bag is out of shape, the sticks may overlap each other or a predetermined number of sticks may not be stored in the packaging bag or the appearance of the packaging bag in which the sticks are sealed may not be suitable as a commodity.
Further, it is preferable that the input machine is capable of flexibly coping with a change in the number of the stick-shaped articles to be input into the packaging bag and a change in the shape (particularly, the length in the longitudinal direction) of the stick-shaped articles.
For example, in the apparatus of patent document 1, when a plurality of rods are stored in a bag in an upright state, if an appropriate amount of rods is stored in a tank for conveying the plurality of rods with respect to the size of the tank, the rods are appropriately supported in the upright state by the inner surface of the tank, and the rods are held in a stable posture in the tank. On the other hand, when the amount of the rod-like object is small compared with the size of the can, or when the length of the rod-like object in the longitudinal direction is short, the rod-like object may fall down in the can. In this case, the required types of tanks are increased, and it is necessary to prepare in advance the placement of parts for fixing the respective tanks and the like in accordance with the types of tanks. Further, depending on the size of the can to be used, various parts such as a guide of the can loading machine need to be changed accordingly. In this way, in an apparatus in which the can needs to be changed in accordance with the change in the number and size of the rod-shaped articles accommodated in the bag, the number of components to be stored in advance increases, and the apparatus needs to be switched, which requires a cost and labor.
In the apparatus disclosed in patent document 2, the posture of the rod-like object is adjusted by swinging the hopper in the horizontal direction, but when the rod-like object is fragile, the rod-like object may be damaged by such swinging. Further, in the apparatus of patent document 2, the plurality of rods are also swung in a tilted posture, but it is difficult to return the posture of the rod that has been temporarily set in the lateral posture to the normal posture only by such a swing. Further, when the rods having an inappropriate posture fall downward, there is a possibility that the rods overlap each other in the vertical direction, and therefore, in the apparatus of patent document 2, the rods after the fall are swung again and aligned. As described above, in the apparatus of patent document 2, the impact due to the swing is applied to the rod in two stages, and therefore, when the rod is fragile, the rod is highly likely to be damaged.
In the apparatus disclosed in patent document 3, since the tank discharge mechanism is provided above the hopper, the distance by which the input material drops from the container to the hopper is large. Therefore, when the input articles are rod-shaped articles, there is a concern that the rod-shaped articles may be vertically overlapped with each other due to differences in the falling timing and the falling speed of each rod-shaped article. The posture of the rods overlapped in the vertical direction is difficult to return to normal by swinging, and such rods may fall down in the lateral direction.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a loading machine capable of appropriately storing a plurality of stick-shaped articles in a standing state in a packaging bag.

Detailed Description
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, although the sizes of the respective elements, the size ratios between the elements, and the like are not necessarily uniform in the drawings, it is easy for those skilled in the art to understand the relationship between the respective elements and the elements from the drawings. In addition, in the drawings, elements may not be illustrated for easy understanding.
Integral structure of device
Fig. 1 is a cross-sectional view of the entire loading machine 10 viewed from the side. Fig. 2 is a plan view of the entire loading machine 10 as viewed from above.
The loading machine 10 is a device for loading a predetermined plurality of rod-shaped articles 12 into a packaging bag 14. The loading machine 10 includes a conveying unit 20, a loading section 30, a 1 st holding hopper 24, a 1 st hopper driving section 26 (see fig. 3 and 4), and a gate section 28.
The conveying unit 20 is configured to sequentially convey a plurality of conveying containers 22 each having an opening 22a on an upper surface thereof and accommodating the rod-like objects 12 (container conveying step). The transport unit 20 of the present embodiment sequentially transports transport containers 22 in a state where the bottom is closed and the opening 22a is open at the top. Each transport container 22 is sandwiched and guided by the pair of guides 51, and moves toward the stopper 63 disposed at the support position P0.
In the conveying unit 20 shown in fig. 1, the conveying containers 22 are placed on the endless conveying belt 52 wound around the conveying rollers 57, and the conveying containers 22 are conveyed in the horizontal direction (the direction from the right to the left in fig. 1) as the conveying belt 52 travels. The conveying roller 57 is engaged with the conveying belt 52 and is driven to rotate by a motor not shown. By rotating the conveying rollers 57, the conveying belt 52 continuously or intermittently travels, and each conveying container 22 is continuously or intermittently conveyed. The plurality of conveyance containers 22 conveyed by the conveyance belt 52 are aligned in a horizontal direction, and the conveyance container 22 at the head of the line is stopped by the stopper 63 and the input portion 30 (i.e., the holding member body portion 60).
A plurality of rods 12 are stored in each of the conveying containers 22, and the number of rods 12 stored in 1 conveying container 22 is smaller than the number of rods 12 finally stored in the packaging bag 14. The number of the rods 12 finally stored in the packaging bag 14 is preferably an integral multiple of the number of the rods 12 stored in 1 conveying container 22, and particularly preferably an integral multiple of or less than the number of the storage chambers 25 included in the 1 st holding hopper 24. In this case, the same number of rod-shaped articles 12 can be stored in each of the plurality of conveyance containers 22. Further, only 1 stick 12 may be stored in each transport container 22, and the same number of sticks 12 may not be necessary to be stored between the transport containers 22.
The loading unit 30 opens the conveyance container 22 disposed at the loading position P1 downward. The loading unit 30 of the present embodiment rotates (i.e., inverts) each of the plurality of conveyance containers 22 to direct the opening 22a downward at the loading position P1. The input unit 30 opens the transport container 22 disposed at the input position P1 downward in a state where at least the bottom 25b of the storage chamber 25 disposed downward in the vertical direction of the transport container 22 disposed at the input position P1 is closed by the gate unit 28 among the plurality of storage chambers 25. As a result, the rod-shaped articles 12 in the conveyance container 22 fall toward the storage chamber 25 disposed vertically below the conveyance container 22, and the rod-shaped articles 12 are stored in the storage chamber 25.
The illustrated input unit 30 includes a servomotor 61 fixed to a later-described reversing unit frame 54 via an attachment plate 59, a reversing shaft 84 coupled to a servomotor output shaft 62 via a coupling 58, and a holding member body 60 coupled to the reversing shaft 84. The servomotor 61 rotates the servomotor output shaft 62 about the axial center, thereby rotating the tumble shaft 84 about the axial center integrally with the servomotor output shaft 62, and the holding member body portion 60 rotates (i.e., revolves) together with the tumble shaft 84. In particular, in the present embodiment, the holding member main body portion 60 can be rotationally moved from the support position P0 to the input position P1 by rotating the servomotor output shaft 62 in the normal direction by 180 °. Further, the holding member main body portion 60 can be rotationally moved from the insertion position P1 to the support position P0 by reversing the rotation of the servomotor output shaft 62 by 180 °.
The holding member main body portion 60 has a shape adapted to block and support each transport container 22 at the support position P0. The pair of container holding cylinders 55 are attached to the holding member main body portion 60. Each container holding cylinder 55 extends the container holding member 56 to press the transport container 22 received by the holding member body 60 against the holding member body 60. Thus, the transport container 22 is fixedly supported by the holding member body 60, and when the holding member body 60 rotates, the transport container 22 also rotates integrally with the holding member body 60. Therefore, the opening 22a of the transport container 22, which is directed upward at the support position P0, is directed downward at the drop position P1. In this way, the conveyance container 22 conveyed by the conveyance unit 20 (i.e., the conveyor belt 52) and disposed at the support position P0 is supported by the holding member main body portion 60 and the container holding cylinder 55. Then, the servomotor output shaft 62 is rotated by 180 ° about the axial center, whereby the holding member body 60 and the container holding cylinder 55 are rotated together with the conveyance container 22, and the conveyance container 22 is moved from the support position P0 to the input position P1.
Further, an inverting section frame 54 (see fig. 1) is attached to a cover 82 provided to cover the 1 st holding hopper 24, and a pair of separation stoppers 53 are fixedly provided on the inverting section frame 54. Each separator stopper 53 extends and contracts the push-out member 53 a. The pair of separation stoppers 53 extend the pushing member 53a, and thereby the pushing member 53a presses the second conveyance container 22 from the top, and separates the second conveyance container 22 from the first conveyance container 22 (see fig. 2). This prevents the two conveyance containers 22 from interfering with each other, and allows the conveyance container 22 at the head of the line to smoothly rotate about the inverting shaft 84 together with the holding member body 60.
The 1 st holding hopper 24 shown in fig. 1 has a plurality of storage chambers 25 (three storage chambers 25 in the present embodiment), and the plurality of storage chambers 25 are provided below the transport container 22 disposed at the drop-in position P1. In fig. 1, the housing chambers 25 are arranged to face each other with the rotating shaft 31 interposed therebetween for easy understanding, but actually, as shown in fig. 3, three housing chambers 25 are arranged at equal intervals around the rotating shaft 31. This is the same in fig. 13, 16, 18, and 19 described later.
The top 25a and bottom 25b of each housing chamber 25 are open. The top portion 25a functions as a receiving port for receiving the rod-like objects 12 from the conveying container 22, and the bottom portion 25b functions as a discharge port for discharging the rod-like objects 12 toward the 2 nd holding hopper 40. The inner side surface of the housing chamber 25 has an inclined surface 25c, and the inclined surface 25c is inclined so as to be closer to the rotation shaft 31 as the position thereof is lower in the vertical direction. Since the storage chamber 25 has the inclined surface 25c, the rod-like objects 12 in the storage chamber 25 fall while being guided by the inclined surface 25c, and the rod-like objects 12 falling from the conveying container 22 are collected toward the rotary shaft 31.
The 1 st holding hopper 24 of the present embodiment has a rotating body 32 provided to be rotatable about a rotating shaft 31, and the plurality of storage chambers 25 are held by the rotating body 32. The rotary shaft 31 is supported by the hopper support member 64, the hopper support member 64 is supported by the hopper support plate 65, and the hopper support plate 65 is supported by the cover 82. The rotary shaft 31 rotatably holds the rotary member 68, and the rotary member 68 and the rotary body 32 rotate integrally.
The cover 82 is formed with a through hole 80 (see fig. 2), and the through hole 80 is disposed between the transport container 22 disposed at the input position P1 and the 1 st holding hopper 24 (particularly, the storage chamber 25 disposed below the transport container 22 disposed at the input position P1 in the vertical direction). At the drop-in position P1, the opening 22a of the conveyance container 22 facing downward in the vertical direction faces the through hole 80, and the rod-like objects 12 stored in the conveyance container 22 drop into the storage chamber 25 through the through hole 80. The through-hole 80 has a diameter equal to or larger than the inner diameter of each transport container 22 (i.e., the diameter of the storage section 23 constituting the storage space for the rod-shaped objects 12), and the cover 82 does not prevent the rod-shaped objects 12 from falling from the transport containers 22 into the storage chamber 25.
The 1 st hopper driving unit 26 (see fig. 3 and 4) moves the 1 st holding hopper 24 to dispose one of the plurality of storage chambers 25 below the vertical direction of the transport container 22 disposed at the drop-in position P1. The first hopper driving unit 26 of the present embodiment rotates the rotating body 32 to dispose any one of the plurality of storage chambers 25 below the vertical direction of the transport container 22 disposed at the input position P1. At this time, an axis line extending in the vertical direction through the center of the downward opening 22a of the conveyance container 22 disposed at the drop position P1 coincides with an axis line extending in the vertical direction through the center of the opening of the ceiling portion 25a of the storage chamber 25 disposed below the conveyance container 22 in the vertical direction. The details of the 1 st hopper driving section 26 will be described later with reference to fig. 3 and 4.
As shown in fig. 1, a door portion 28 is provided at the bottom 25b of each of the plurality of storage chambers 25. The door 28 closes and opens the bottom 25b of each of the plurality of storage chambers 25. The door 28 of the present embodiment can simultaneously open the bottoms 25b of the plurality of storage chambers 25. The term "simultaneous" as used herein does not necessarily mean strict simultaneity, and simultaneity is referred to herein as "simultaneous" to the extent that the rods 12 stored in the plurality of storage chambers 25 start falling substantially simultaneously through the openings of the bottom portions 25b of the storage chambers 25. Therefore, even if the opening timings of the bottom portions 25b of the plurality of storage chambers 25 vary by, for example, about 0.1 second or less (more preferably about 0.05 second or less), it can be said that the bottom portions 25b of the plurality of storage chambers 25 are simultaneously opened. Further, details of the door section 28 will be described later with reference to fig. 5 to 9.
The distance from the downward opening 22a of the conveyance container 22 disposed at the drop position P1 to the gate 28 provided to close the bottom 25b of the storage chamber 25 disposed vertically below the conveyance container 22 (see reference numeral "D1" in fig. 13) is preferably less than twice the length of the rod-like objects 12 in the longitudinal direction (see reference numeral "D2" in fig. 13). This can effectively prevent the rod-shaped articles 12 dropped from the conveying container 22 from vertically overlapping each other in the storage chamber 25.
The loading machine 10 further includes a 2 nd holding hopper 40 disposed below the plurality of storage chambers 25 in the vertical direction. The gate portion 28 opens the bottom 25b of two or more or 1 of the plurality of storage chambers 25 in which the rod 12 is stored, and thereby the rod 12 in the two or more or 1 of the storage chambers 25 is dropped into the 2 nd holding hopper 40.
The top portion 40a and the bottom portion 40b of the 2 nd holding hopper 40 are open, the top portion 40a functions as a receiving port for receiving the rod-like objects 12 from the respective receiving chambers 25, and the bottom portion 40b functions as a discharge port for discharging the rod-like objects 12 toward the opening/closing unit 66. The inner side surface of the 2 nd holding hopper 40 has an inclined surface 40c, and the inclined surface 40c is inclined so as to be closer to the radial center as the position thereof is lower in the vertical direction. Since the 2 nd holding hopper 40 has the inclined surface 40c, the rod-like objects 12 falling from the respective storage chambers 25 are collected toward the center of the 2 nd holding hopper 40.
Further, the distance from the gate portion 28 provided so as to close the bottom portion 25b of the storage chamber 25 disposed vertically below the transport container 22 disposed at the loading position P1 to the bottom portion 40b of the 2 nd holding hopper 40 (see reference numeral "D3" in fig. 13) is preferably less than twice the length of the rod-like objects 12 in the longitudinal direction (see reference numeral "D2" in fig. 13). This can effectively prevent the rod-shaped articles 12 dropped from the respective storage chambers 25 from overlapping each other in the vertical direction in the 2 nd holding hopper 40.
The feeder 10 also includes a discharge device 36. The discharge device 36 conveys the transport container 22 from the intake position P1 to the discharge position P2, and discharges the transport container 22 to a discharge unit (shooter) 34 provided at the discharge position P2. As shown in fig. 2, the discharge device 36 of the present embodiment includes a pushing portion 38 and a container guide portion 39. Pushing portion 38 pushes transport container 22 from loading position P1 to discharge position P2.
Container guide 39 is fixed to cover 82, and guides transport container 22 pushed by push-in unit 38 from intake position P1 to discharge position P2. Specifically, the two container guides 39 are arranged in parallel to each other, each container guide 39 has a step portion, and the conveyance container 22 arranged at the input position P1 is arranged on the step portions of the two container guides 39. The distance between the step portions of the two container guides 39 is constant, and is the same as or slightly larger than the outer diameter of the conveyance container 22. The step portions of the two container guides 39 regulate the movement trajectory of the conveyance container 22, and the conveyance container 22 is guided from the intake position P1 to the discharge position P2 between the step portions. In this way, the two container guides 39 slidably support the empty transport container 22, thereby preventing the transport container 22 from deviating from the predetermined movement locus and discharging the transport container 22 to the discharge unit 34 disposed at the discharge position P2. Further, the portion of each container guide 39 corresponding to the input position P1 and located above the through hole 80 in the vertical direction is cut away so as not to obstruct the rod-shaped articles 12 dropping from the conveyance container 22 disposed at the input position P1.
In the loading machine 10 shown in fig. 2, the pushing portion 38 has an L-shaped plan view. The drive unit of the pushing portion 38 includes a 1 st rotating body 77 and a 2 nd rotating body 78, and a shaft eccentric block 72 is coupled to the 1 st rotating body 77 via a center shaft 75, and a shaft eccentric block 73 is coupled to the 2 nd rotating body 78 via a center shaft 76. The shaft eccentric block 72 is coupled to the push-in portion 38 via a fixed shaft 71, and the shaft eccentric block 73 is coupled to the push-in portion 38 via a fixed shaft 74. The shaft eccentric block 72 and the shaft eccentric block 73 constitute a link mechanism, and the shaft eccentric block 72 and the shaft eccentric block 73 are rotatably coupled to the push-in portion 38. On the other hand, the shaft eccentric block 72 is fixed to the center shaft 75 and rotates together with the center shaft 75, and the shaft eccentric block 73 is fixed to the center shaft 76 and rotates together with the center shaft 76. The 1 st rotating body 77 is fixed to the center shaft 75 and rotates together with the center shaft 75, and the 2 nd rotating body 78 is fixed to the center shaft 76 and rotates together with the center shaft 76. Therefore, the pushing portion 38 moves between the input position P1 and the discharge position P2 by rotating the 1 st rotor 77 and the 2 nd rotor 78 about the center axis 75 and the center axis 76. The 1 st rotating body 77 and the 2 nd rotating body 78 can be rotated by an arbitrary driving device.
Hopper rotating mechanism
Fig. 3 is a view showing a state in which the 1 st holding hopper 24 disposed in the cover 82 is viewed from above. Fig. 3 shows a state in which the 1 st holding hopper 24 is cut in a horizontal direction perpendicular to the extending direction of the rotary shaft 31, and particularly shows a state in which the 1 st holding hopper 24 is cut at a position above the rotary body 32.
The rotating body 32 is formed in a disk shape, and the storage chambers 25 are provided so as to penetrate the rotating body 32. The outer peripheral portion of the rotating body 32 has a gear shape, and the operating shaft 86 engages with the outer peripheral portion of the rotating body 32. The outer peripheral portion of the operating shaft 86 has a gear shape that meshes with the gear shape of the rotating body 32, and the rotating body 32 is driven and rotated by rotating the operating shaft 86 around the axis.
Fig. 4 is a sectional view showing a rotation driving structure of the operating shaft 86. The operating shaft 86 is connected to a motor 88 via a speed reducer 87. The rotational power output from the output shaft of the motor 88 is increased in torque by the speed reducer 87 and then transmitted to the operating shaft 86. Thereby, the operating shaft 86 drives and rotates the rotating body 32. In this way, in the present embodiment, the motor 88, the speed reducer 87, and the operation shaft 86 are provided as the 1 st hopper driving section 26 that moves the 1 st holding hopper 24 (i.e., each storage chamber 25). Further, the rotating body 32 intermittently rotates via the operating shaft 86, and the storage chambers 25 are sequentially disposed below the transport container 22 disposed at the loading position P1 in the vertical direction.
Door opening and closing mechanism
Fig. 5 is a plan view of the opening/closing mechanism of the door 28 viewed from above, and shows a state in which the door 28 is closed. Fig. 6 is a view of the opening and closing mechanism of the door portion 28 shown in fig. 5, as viewed from the direction indicated by the arrow "a" in fig. 5. Fig. 7 is a view of the opening and closing mechanism of the door portion 28 viewed from the direction indicated by the arrow "B" in fig. 5. Fig. 8 is a plan view of the opening/closing mechanism of the door 28 viewed from above, and shows a state where the door 28 is opened. Fig. 9 is a view of the opening and closing mechanism of the door portion 28 shown in fig. 8, as viewed from the direction indicated by the arrow "a" in fig. 8. In each of fig. 5 to 9, some elements are not illustrated for ease of understanding. For example, in fig. 6 and 9, the driver 96 is not illustrated. In addition, strictly speaking, the position of the housing chamber 25 shown in fig. 7 is different from the position of the housing chamber 25 shown in fig. 5.
In the present embodiment, two gate portions 28 are provided, and each gate portion 28 is connected to the rail 90 via a moving body 91. Each moving body 91 is slidably engaged with the rail 90 fixed to the cover 82 with respect to the rail 90, and each door portion 28 is provided so as to be movable along the rail 90 together with the moving body 91. A connecting block 92 is fixed to each moving body 91, and each connecting block 92 is connected to a connecting rod 94 via a connecting shaft 93. The connecting rod 94, the connecting shafts 93, and the connecting block bodies 92 constitute a link mechanism, and the connecting portions therebetween are rotatably provided. The connecting shaft 93 is connected to both end portions of the connecting rod 94, and the rotating shaft 95 of the actuator 96 is fixed to a central portion of the connecting rod 94. When the rotation shaft 95 is rotated about the axis, the link 94 rotates about the axis together with the rotation shaft 95.
The door mechanism 69 for opening and closing the door 28 has the above-described structure, and can move the door 28 by rotating the rotary shaft 95 by driving the actuator 96 fixed to the cover 82. This enables the bottom 25b of each storage chamber 25 forming the discharge port to be closed and opened by the gate portion 28. That is, the position of each moving body 91 on the rail 90 is determined according to the rotation state of the rotating shaft 95 and the posture of the connecting rod 94. Therefore, by rotating the rotary shaft 95 to set the state shown in fig. 5 to 7, the gate portions 28 moving together with the moving body 91 come into contact with each other, and the bottom portions 25b of all the storage chambers 25 are covered and closed by the gate portions 28 (see fig. 5). On the other hand, when the rotation shaft 95 is rotated to set the state shown in fig. 8 to 9, the gate portions 28 are separated from each other, and the bottom portions 25b of all the housing chambers 25 are not covered with the gate portions 28 but are opened (see fig. 8).
For example, in a state where the bottom 25b of each of the storage chambers 25 is closed by the gate 28 (see fig. 5), the gate 28 prevents the rod-like objects 12 stored in each of the storage chambers 25 from falling. On the other hand, in a state where the bottom 25b of each storage chamber 25 is open (see fig. 8), the rod-shaped objects 12 stored in each storage chamber 25 fall downward.
Hopper opening and closing mechanism
Fig. 10 is a plan view showing the opening/closing unit 66, and shows a state where the opening/closing unit 66 is closed. Fig. 11 is a side view showing the opening and closing unit 66, and shows a state where the opening and closing unit 66 is closed. Fig. 12 is a side view showing the opening and closing unit 66, and shows a state where the opening and closing unit 66 is opened.
The opening/closing unit 66 has a 1 st opening/closing portion 66a and a 2 nd opening/closing portion 66 b. The 1 st opening/closing portion 66a and the 2 nd opening/closing portion 66b perform an opening/closing operation, and the 1 st opening/closing portion 66a and the 2 nd opening/closing portion 66b can cover the bottom portion 40b of the 2 nd holding hopper 40 to close the bottom portion 40b (see fig. 11), while the 1 st opening/closing portion 66a and the 2 nd opening/closing portion 66b can open the bottom portion 40b without covering the bottom portion 40b (see fig. 12).
The 1 st opening/closing portion 66a is fixed to the 1 st opening/closing portion 111 by two 1 st fixing members 113, and the 2 nd opening/closing portion 66b is fixed to the 2 nd opening/closing portion 112 by two 2 nd fixing members 114. The 1 st opening/closing portion 111 is rotatably coupled to the door holding member 105 via a rotating shaft 115, and the 2 nd opening/closing portion 112 is rotatably coupled to the door holding member 105 via a rotating shaft 116. The 1 st opening/closing unit 111 and the 2 nd opening/closing unit 112 are connected to each other via a link mechanism 109. The 1 st opening/closing part 111 and the 2 nd opening/closing part 112 are interlocked with each other via the link mechanism 109, and the 1 st opening/closing part 111 and the 2 nd opening/closing part 112 exhibit mirror-symmetrical operations with each other. The 1 st opening/closing portion 66a moves integrally with the 1 st fixing member 113 and the 1 st opening/closing portion 111 and rotates about the rotation shaft 115, and the 2 nd opening/closing portion 66b moves integrally with the 2 nd fixing member 114 and the 2 nd opening/closing portion 112 and rotates about the rotation shaft 116.
The 2 nd opening/closing unit 112 is connected to the cylinder shaft 67a of the opening/closing cylinder 67 via a connecting member 108, and the opening/closing cylinder 67 is fixed to the frame 101 via a cylinder holder 107. Further, the door holding member 105 is fixed to the frame 101 via an L-shaped frame 106. Further, a through hole 102 is formed in the frame 101, and the through hole 102 faces the ceiling portion 40a of the 2 nd holding hopper 40.
With the opening/closing means 66, the 1 st opening/closing portion 66a and the 2 nd opening/closing portion 66b are opened and closed according to the amount of projection of the cylinder shaft 67a of the opening/closing cylinder 67. For example, as shown in fig. 10 and 11, when the amount of projection of the cylinder shaft 67a is small, the 1 st opening/closing part 66a and the 2 nd opening/closing part 66b are disposed at the closed position and cover the bottom 40b of the 2 nd holding hopper 40. On the other hand, as shown in fig. 12, when the amount of projection of the cylinder shaft 67a is large, the connecting member 108 is disposed on the 1 st opening/closing portion 66a side. In this case, the 2 nd opening/closing portion 112 swings about the rotation shaft 116, and a force is transmitted from the 2 nd opening/closing portion 112 to the 1 st opening/closing portion 111 via the link mechanism 109 to swing the 1 st opening/closing portion 111 about the rotation shaft 115. Thereby, the 1 st opening/closing portion 66a and the 2 nd opening/closing portion 66b are opened, and the bottom 40b of the 2 nd holding hopper 40 is opened.
Diameter of opening
In the loading machine 10 having the above-described configuration, the diameters of the respective storage chambers 25, the 2 nd holding hopper 40, and the opening/closing unit 66 are determined in the following manner. That is, the diameter of the opening/closing means 66 (i.e., the 1 st opening/closing part 66a and the 2 nd opening/closing part 66b) (see fig. 12) when opening is determined according to the diameter of the opening of the packaging bag 14 (i.e., the inlet of the stick 12) to be used. Specifically, the opening diameter of the opening/closing means 66 is set to be equal to or smaller than the diameter of the opening of the packaging bag 14 (preferably smaller than the diameter of the opening of the packaging bag 14). The bottom 40b of the 2 nd holding hopper 40 is set to be equal to or smaller than the diameter of the opening/closing unit 66 (i.e., the inlet of the rod-like object 12) (preferably, smaller than the diameter of the opening/closing unit 66). The diameter of the top 40a of the 2 nd holding hopper 40 is determined according to the diameter of the bottom 25b of the storage chamber 25, and the diameter of the top 40a of the 2 nd holding hopper 40 and the diameter of the bottom 25b of the storage chamber 25 are set so that all the bottoms 25b of the storage chamber 25 can be covered with the top 40a of the 2 nd holding hopper 40. Further, the diameter of the bottom 40b of the 2 nd holding hopper 40 is set smaller than the diameter of the top 40 a.
The diameter of the ceiling portion 25a of each storage chamber 25 is determined according to the diameter of the opening portion 22a of the transport container 22, and the diameters of the storage portion 23 and the opening portion 22a of each transport container 22 are equal to or smaller than the opening diameter of the ceiling portion 25a of each storage chamber 25, and preferably smaller than the opening diameter of the ceiling portion 25 a. Thus, when the conveying containers 22 are turned over at the drop-in position P1 and the opening 22a is directed downward in the vertical direction, the rod-shaped articles 12 can be smoothly dropped from the storage portion 23 of the conveying container 22 into the storage chamber 25.
Function of
Next, the operation of the loading machine 10 having the above-described configuration will be described.
Fig. 13 to 19 are diagrams showing the operation state of the loading machine 10.
As described above, the transport container 22 (see fig. 1 and 2) placed at the support position P0 is reversed by the loading unit 30 and placed at the loading position P1 with the opening 22a facing downward as shown in fig. 13 and 14. At this time, the bottom 25b of each housing chamber 25 is closed by the door 28. Thus, the rod-shaped articles 12 in the conveyance container 22 disposed at the drop position P1 fall toward the storage chamber 25 disposed vertically below the conveyance container 22 and are stored in the storage chamber 25.
After the transport container 22 moves from the support position P0 to the input position P1, the amount of protrusion of the container holding member 56 by the container holding cylinder 55 is reduced (see fig. 14), the container holding members 56 are arranged at the retracted positions, and the support of the transport container 22 by the input unit 30 (i.e., the holding member body 60 and the container holding cylinder 55) is released. After the transport container 22 moves from the support position P0 to the loading position P1, a new transport container 22 is placed at the support position P0. That is, the amount of projection of the pushing member 53a of each separation stopper 53 is reduced, each pushing member 53a is disposed at the retreat position, and the new transport container 22 is advanced toward the stopper 63.
Then, as shown in fig. 15, the 1 st rotating body 77 and the 2 nd rotating body 78 are rotated, and the empty transport container 22 placed at the input position P1 is pushed by the pushing section 38 and moves along the container guide 39 toward the discharge position P2. The pushing portion 38 connected to the 1 st rotating body 77 and the 2 nd rotating body 78 via the link mechanism (i.e., the shaft eccentric block 72 and the shaft eccentric block 73) can push out the transport container 22 while maintaining the same contact angle with respect to the transport container 22.
While the transport container 22 is moving from the loading position P1 to the discharge position P2, the rotating body 32 is rotated by the 1 st hopper driving unit 26, and the storage chamber 25 in which the stick-shaped objects 12 are not stored is disposed below the loading position P1 in the vertical direction as shown in fig. 16. As described above, since 3 storage chambers 25 are provided at equal intervals in the present embodiment, the new storage chamber 25 can be disposed below the drop-in position P1 in the vertical direction by rotating the rotating body 32 by 120 ° about the rotating shaft 31. Further, when the rotating body 32 rotates, the door portion 28 maintains a state in which the bottom portion 25b of each housing chamber 25 is closed. On the other hand, the servomotor output shaft 62 rotates to move the holding member main body portion 60 and the container holding cylinder 55 from the thrown position P1 to the support position P0.
Then, the empty conveyance container 22 moved to the discharge position P2 rolls down into the discharge portion 34 as shown in fig. 17 (container discharge step). On the other hand, the container holding member 56 of the container holding cylinder 55 is extended, and the new transport container 22 disposed at the support position P0 is sandwiched and supported by the holding member main body portion 60 and the container holding cylinder 55. Whether or not the new conveyance container 22 is properly placed at the support position P0 is detected by a sensor, not shown, and a detection signal of the sensor is transmitted to a controller, not shown, for controlling each container holding cylinder 55. The controller controls each container holding cylinder 55 based on a detection signal of the sensor.
Then, the input unit 30 moves the new transport container 22 from the support position P0 to the input position P1, and drops the rod-shaped article 12 from the inside of the transport container 22 into the storage chamber 25 as shown in fig. 18. This allows the rod-like objects 12 to be stored in the storage chamber 25 disposed vertically below the drop position P1.
By repeating the above operation, the rod-like objects 12 are stored in all the storage chambers 25. Thereafter, the door 28 is opened to open the bottom 25b of each storage chamber 25. As a result, as shown in fig. 19, the rod-like objects 12 are dropped from all the storage chambers 25 at the same time, and the rod-like objects 12 are stored in the 2 nd holding hopper 40 (filler collecting step). At this time, the opening and closing unit 66 (the 1 st opening and closing part 66a and the 2 nd opening and closing part 66b) is closed, and the plurality of rod-shaped objects 12 are stored across the 2 nd holding hopper 40 and the opening and closing unit 66.
Then, by opening the opening/closing unit 66 (the 1 st opening/closing portion 66a and the 2 nd opening/closing portion 66b), the rod-like objects 12 in the 2 nd holding hopper 40 fall toward the packaging bag 14 (see fig. 1) disposed below the opening/closing unit 66. As described above, the stick 12 is biased toward the center by the inclined structure of the 2 nd holding hopper 40 (particularly the inclined surface 40c) and the opening/closing unit 66 (the 1 st opening/closing portion 66a and the 2 nd opening/closing portion 66b), and therefore, the plurality of sticks 12 can be easily and appropriately stored in the packaging bag 14 in an erected state.
As described above, according to the loading machine 10 of the present embodiment, the plurality of sticks 12 can be appropriately stored in the packaging bag 14 in the standing state. In particular, by making the inner diameter of the transport container 22 (the diameter of the storage section 23) close to the opening diameter of the top 25a of each storage chamber 25, the rods 12 can be stored in the storage chambers 25 while maintaining the posture of the rods 12 in the transport container 22.
Further, the number of the stick-shaped articles 12 stored in the packaging bag 14 can be easily changed by changing the number of the storage chambers 25 in which the stick-shaped articles 12 are stored among the plurality of (3 in the present embodiment) storage chambers 25 of the 1 st holding hopper 24. For example, when the number of the rods 12 to be stored in the packaging bag 14 is required to be equal to the number of the rods 12 to be stored in the 3 transport containers 22, the rods 12 from the respective transport containers 22 may be stored in the respective storage chambers 25 of the 3 storage chambers 25 as described above. On the other hand, when the number of the rods 12 to be stored in the packaging bag 14 is equal to the number of the rods 12 to be stored in the two transport containers 22, the rods 12 from each transport container 22 are stored in only the two storage chambers 25, and the rods 12 from each transport container 22 are not stored in the other storage chamber 25. In this state, the bottom 25b of each receiving chamber 25 is opened by opening the door 28, and the rods 12 corresponding to the number of rods 12 received in the two conveying containers 22 are received in the 2 nd holding hopper 40. Then, by opening the opening and closing unit 66, the rod-shaped articles 12 corresponding to the number of the rod-shaped articles 12 stored in the two conveying containers 22 are stored in the packaging bag 14.
In this way, the number of the rods 12 stored in the packaging bag 14 can be changed by simply adjusting the number of the storage chambers 25 for storing the rods 12 from the transport container 22. Therefore, even when the specification of the packaging bag 14 to be used is changed and the number of the rods 12 stored in the packaging bag 14 is changed, it is possible to cope with this without replacing the transport container 22 or the like. When the number of the rods 12 stored in the packaging bag 14 is changed, the 2 nd holding hopper 40 may be replaced with another 2 nd holding hopper 40 having a size corresponding to the changed number of the rods 12.
In addition, when the number of rods 12 stored in 1 packaging bag 14 is adjusted by the number of storage chambers 25 actually used, the number of rods 12 stored in 1 storage chamber 25 can be made smaller than the number of rods 12 stored in packaging bag 14. Therefore, the number of the rod-shaped articles 12 stored in 1 conveying container 22 can be reduced, and a relatively small conveying container 22 can be used, and in particular, the inner diameter (the diameter of the storage portion 23) of each conveying container 22 can be reduced. By using the transport container 22 having a small inner diameter, even a rod-shaped object 12 having a small length in the longitudinal direction can be stored in the transport container 22 in an upright state. Therefore, according to the loading machine 10 of the present embodiment, even if the length of the rod-like objects 12 in the longitudinal direction changes, the rod-like objects 12 can be appropriately conveyed by the same conveying container 22.
Further, by disposing the plurality of housing chambers 25 on the circular orbit, it is possible to save the installation space of the housing chambers 25, and to easily collect the rod-like objects 12 housed in the housing chambers 25 in the 2 nd holding hopper 40 when the rod-like objects 12 are dropped.
Further, by inclining the inclined surface 25c of each of the plurality of housing chambers 25 toward the common rotation shaft 31, the rod-shaped objects 12 from each of the housing chambers 25 can be gathered in the vicinity of the central axis. This can increase the packing density of the rods 12 in the 2 nd holding hopper 40, and can easily put a plurality of rods 12 into a relatively tight packaging bag 14.
Further, by providing the discharge unit 34 at a position different from the input position P1 in the horizontal direction, it is not necessary to provide the discharge unit 34 between the transport container 22 disposed at the input position P1 and each of the storage chambers 25. This makes it possible to reduce the distance by which the rod 12 falls from the conveyance container 22 into each storage chamber 25 by bringing the conveyance container 22 and each storage chamber 25 close to each other. Therefore, the impact applied to the rod 12 during the fall can be reduced to prevent the rod 12 from being damaged, and the deformation of the posture of the rod 12 can be effectively suppressed.
Modification example 1
Fig. 20 to 23 are views relating to a loading machine 10 according to a modification, and particularly show the structure of the storage chamber 25. Fig. 20 and 22 are plan views of the storage chambers 25 viewed from above. Fig. 21 and 23 are cross-sectional views of 1 housing chamber 25 viewed from the side. Fig. 20 and 21 show a state in which the rod 12 in each housing chamber 25 is not pressed by the pressing rod 133, and fig. 22 and 23 show a state in which the rod 12 in each housing chamber 25 is pressed by the pressing rod 133.
In the present modification, a pushing unit 130 is provided for each of the storage chambers 25, and the pushing unit 130 is configured to push the rod-like objects 12 stored inside each of the plurality of storage chambers 25 in a direction including a horizontal component (in fig. 20 to 23, in the horizontal direction).
Each storage chamber 25 is provided with a notch 135. Each pushing unit 130 includes a base 131 fixed to the cover 82, an air cylinder 132 fixed to the base 131, and a pressing rod 133 provided at a tip end of an air cylinder shaft of the air cylinder 132. Each pressing lever 133 is a member that enters the corresponding notch 135 and presses the rod-shaped object 12 stored inside the corresponding storage chamber 25 toward the center (the rotary shaft 31 in the present embodiment).
As shown in fig. 20 and 21, the plurality of rods 12 (particularly, the rods 12 arranged near the inclined surface 25 c) stored in the storage chambers 25 may be arranged obliquely with respect to the vertical direction. The pushing unit 130 is a device for correcting the posture of the rod 12 that is disposed obliquely, and presses the rod 12 to extend the rod 12 in the vertical direction.
As shown in fig. 20 and 21, when the amount of projection of the cylinder shaft of the cylinder 132 is small, the pressing rod 133 is disposed at the retracted position outside the housing chamber 25, and the rod-like object 12 in the housing chamber 25 is not pressed by the pressing rod 133. On the other hand, as shown in fig. 22 and 23, when the amount of projection of the cylinder shaft of the cylinder 132 is large, the pressing rod 133 enters the cutout 135, and the rod 12 (particularly, the rod 12 near the inclined surface 25 c) in the housing chamber 25 is pressed by the pressing rod 133. Thereby, the posture of the rod 12 in the housing chamber 25 is corrected, and the rod 12 in the housing chamber 25 is arranged to extend in the vertical direction.
The plurality of rods 12 immediately after dropping from the conveyance container 22 into each storage chamber 25 generally include rods 12 inclined as shown in fig. 21, but the rods 12 in the storage chambers 25 can be extended in the vertical direction by the push-in unit 130. In particular, by pressing the rod-shaped objects 12 in the respective storage chambers 25 toward the common rotation shaft 31, the rod-shaped objects 12 in the respective storage chambers 25 can be brought close to the rotation shaft 31, and the degree of aggregation of the rod-shaped objects 12 can be increased. By performing the correction by the push-in unit 130, when the door 28 is opened, the plurality of rods 12 in the standing state can be smoothly dropped in the vertical direction from the bottom 25b of the storage chamber 25.
Modification example 2
The 2 nd holding hopper 40 of the above embodiment and the 1 st modification has a funnel shape in which a single holding chamber is provided inside, but the 2 nd holding hopper 40 may have a plurality of holding chambers.
Specifically, one or more holding chambers of the plurality of holding chambers of the 2 nd holding hopper 40 may be disposed below the respective storage chambers 25 of the 1 st holding hopper 24 in the vertical direction. Each of the plurality of holding chambers of the 2 nd holding hopper 40 may be disposed below at least 1 or more of the plurality of storage chambers 25 of the 1 st holding hopper 24 in the vertical direction.
In the case where the 2 nd holding hopper 40 has a plurality of holding chambers, typically, the storage chamber 25 of the 1 st holding hopper 24 and the holding chamber of the 2 nd holding hopper 40 correspond to each other one by one. That is, the number of the plurality of holding chambers of the 2 nd holding hopper 40 is the same as the number of the plurality of receiving chambers 25 of the 1 st holding hopper 24, and the holding chambers independent of each other are arranged below the respective receiving chambers 25 in the vertical direction.
Hereinafter, a typical embodiment of the 2 nd holding hopper 40 having a plurality of holding chambers will be described with reference to the drawings.
Fig. 24 to 26 are views showing an aspect of the 2 nd holding hopper 40, fig. 24 is a plan view of the 2 nd holding hopper 40 as viewed from above, fig. 25 is a perspective view showing an external appearance of the 2 nd holding hopper 40, and fig. 26 is a perspective view showing a perspective state (a state showing an outline portion) of the 2 nd holding hopper 40. The 2 nd holding hopper 40 shown in fig. 24 to 26 includes: a tapered portion 41 forming a top portion 40 a; and a cylindrical portion 42 connected to the tapered portion 41 and forming a bottom portion 40 b. A partition body 43 is disposed inside the 2 nd holding hopper 40, and a space inside the 2 nd holding hopper 40 (i.e., a space inside the tapered portion 41 and a space inside the cylindrical portion 42) is divided into a plurality of holding chambers 45 (3 holding chambers 45 in fig. 24 to 26) by the partition body 43. In the present embodiment, the storage chambers 25 of the 1 st holding hopper 24 and the holding chambers 45 of the 2 nd holding hopper 40 correspond one-to-one, and a single holding chamber 45 is disposed below each of the 3 storage chambers 25 (see fig. 3 and the like) of the 1 st holding hopper 24.
Fig. 27 to 28 are views showing another embodiment of the 2 nd holding hopper 40, fig. 27 is a plan view of the 2 nd holding hopper 40 as viewed from above, and fig. 28 is a perspective view showing an appearance of the 2 nd holding hopper 40. The 2 nd holding hopper 40 shown in fig. 27 to 28 is basically configured in the same manner as the 2 nd holding hopper 40 shown in fig. 24 to 26 described above, but does not include a cylindrical portion (see reference numeral "42" in fig. 24 to 26). That is, the 2 nd holding hopper 40 of the present embodiment has the tapered portion 41, the partition body 43 is disposed inside the tapered portion 41, and the space inside the 2 nd holding hopper 40 (i.e., the space inside the tapered portion 41) is divided into a plurality of holding chambers 45 (3 holding chambers 45 in fig. 27 to 28) by the partition body 43.
In each of the 2 nd holding hoppers 40 shown in fig. 24 to 26 and the 2 nd holding hopper 40 shown in fig. 27 to 28, the partition body 43 extends in a range from the top portion 40a to the bottom portion 40b, and the entire space inside the 2 nd holding hopper 40 is divided into the plurality of holding chambers 45 by the partition body 43. However, the extension range of the partition body 43 is not limited to this, and for example, the partition body 43 may not be disposed near the top portion 40a and/or the bottom portion 40 b. In order to open the gate 28 and appropriately guide the rod-like objects 12 from the respective receiving chambers 25 of the 1 st holding hopper 24 to the corresponding holding chambers 45, it is preferable that a partition body 43 is provided at or near the top portion 40 a. In addition, the partition body 43 may not be present at or near the bottom portion 40b in order to cause the rod-like objects 12 held in the plurality of holding chambers 45 to fall from the 2 nd holding hopper 40 in a gathered state.
Further, although the separation body 43 is formed by a member separate from the members forming the tapered portion 41 and the cylindrical portion 42 in the 2 nd holding hopper 40 shown in fig. 24 to 26 and the 2 nd holding hopper 40 shown in fig. 27 to 28, the tapered portion 41, the cylindrical portion 42, and the separation body 43, the tapered portion 41 and the separation body 43, or the cylindrical portion 42 and the separation body 43 may be formed by an integrally provided member. Therefore, for example, a plurality of holding chambers 45 may be formed by removing a part of an integrally provided member.
Fig. 29 to 30 are views showing still another embodiment of the 2 nd holding hopper 40, fig. 29 is a plan view of the 2 nd holding hopper 40 as viewed from above, and fig. 30 is a perspective view showing an appearance of the 2 nd holding hopper 40. The 2 nd holding hopper 40 shown in fig. 29 to 30 includes a plurality of cylindrical bodies 46 (3 cylindrical bodies 46 in fig. 29 to 30) having a space inside, and a plurality of holding chambers 45 are formed by the space inside the cylindrical bodies 46. In the present embodiment, the storage chambers 25 of the 1 st holding hopper 24 and the holding chambers 45 (i.e., the cylindrical bodies 46) of the 2 nd holding hopper 40 correspond to each other, and the individual holding chambers 45 (i.e., the cylindrical bodies 46) are disposed below the 3 storage chambers 25 (see fig. 3 and the like) of the 1 st holding hopper 24. The plurality of holding chambers 45 are disposed so as to gradually come close to each other as they come close to the bottom portion 40b, and the rod-like objects 12 stored in the plurality of holding chambers 45 can be dropped from the 2 nd holding hopper 40 in a gathered state.
In the 2 nd holding hopper 40 shown in fig. 29 to 30, the sizes of the top portion 40a and the bottom portion 40b of each holding chamber 45 (i.e., the inner diameter of each cylindrical body 46) are not particularly limited, and the diameter of the top portion 40a of each holding chamber 45 may be larger than the diameter of the bottom portion 40b, smaller than the diameter of the bottom portion 40b, or the same as the diameter of the bottom portion 40 b. Each of the cylindrical bodies 46 shown in fig. 29 to 30 has a cylindrical shape in which the cross-sectional shapes of the inner wall surface and the outer wall surface are perfect circles, but the specific shape of each of the cylindrical bodies 46 is not particularly limited, and the cross-sectional shapes of the inner wall surface and the outer wall surface of the cylindrical body 46 may be polygonal, elliptical, or any other shape. Further, although the plurality of cylindrical bodies 46 shown in fig. 29 to 30 are configured independently of each other, the plurality of cylindrical bodies 46 (i.e., the plurality of holding chambers 45) may be formed by an integrally provided member.
As described above, the 2 nd holding hopper 40 of the present modification (i.e., the 2 nd holding hopper 40 shown in fig. 24 to 26, the 2 nd holding hopper 40 shown in fig. 27 to 28, and the 2 nd holding hopper 40 shown in fig. 29 to 30) has a plurality of holding chambers 45. Thus, the rod-shaped objects 12 falling from the respective receiving chambers 25 of the 1 st holding hopper 24 toward the 2 nd holding hopper 40 can be held in the corresponding holding chambers 45 having a compact spatial size, and the posture of the rod-shaped objects 12 in the respective holding chambers 45 can be effectively prevented from being distorted.
That is, in the case where the 2 nd holding hopper 40 has only a single holding chamber 45, the rod-like objects 12 from all the storage chambers 25 of the 1 st holding hopper 24 are guided to the same holding chamber 45. In this case, since the size of the single holding chamber 45 is determined according to the total amount of the rods 12 stored in all the storage chambers 25, the spatial size of the single holding chamber 45 is larger than that of each rod 12, and each rod 12 easily falls down in the holding chamber 45. In particular, when the bottom portions 25b of the plurality of storage chambers 25 are opened and closed using the common door portion 28, the opening timings of the bottom portions 25b do not always coincide between the storage chambers 25, and the bottom portion 25b of one storage chamber 25 may be opened before the bottom portions 25b of the other storage chambers 25. In this case, the stick 12 falling first from the storage chamber 25 is easily fallen down in the holding chamber 45 and is easily pushed downward by another stick 12 falling later.
However, as in the present modification, since the 2 nd holding hopper 40 has a plurality of holding chambers 45, the spatial size of each holding chamber 45 can be made compact. This makes it difficult for the rods 12 to fall down in the holding chambers 45, and the posture of the rods 12 can be kept stable in a desired state in the holding chambers 45. In particular, by allocating the independent holding chambers 45 to the independent storage chambers 25, the rod-shaped articles 12 can be stably held in the storage chambers 25 without being affected by the difference in the opening timing of the bottom portions 25b of the storage chambers 25.
Further, a plurality of holding chambers 45 may be provided, a common holding chamber 45 (i.e., 1 holding chamber 45) may be allocated to two or more storage chambers 25, and the rod-like objects 12 falling from the two or more storage chambers 25 may be guided to the common holding chamber 45. In this case, it is preferable to allocate two or more storage chambers 25 having the same or substantially the same opening timing of the bottom portion 25b to the common holding chamber 45. For example, the configuration in which the common holding chamber 45 is allocated to two of the plurality of storage chambers 25 of the 1 st holding hopper 24 can be conceptually explained as the holding chamber 45 allocated to each storage chamber 25 at a ratio corresponding to 0.5 (that is, 50%), but it can be said that 1 holding chamber 45 is disposed below each of the two storage chambers 25 in the vertical direction, and the common holding chamber 45 is disposed below the two storage chambers 25 in the vertical direction.
In the 2 nd holding hopper 40 shown in fig. 24 to 26 and the 2 nd holding hopper 40 shown in fig. 27 to 28, each rod 12 is guided by the inner wall surface (i.e., the inclined surface 40c) of the tapered portion 41 so that each rod 12 approaches the center (i.e., the central axis extending in the vertical direction) of the 2 nd holding hopper 40. In the 2 nd holding hopper 40 shown in fig. 29 to 30, the tubular bodies 46 are disposed so that the bottom portions 40b are closer to each other than the top portions 40a, and the rod-like objects 12 held in the holding chambers 45 are guided so as to be closer to the center of the 2 nd holding hopper 40 (i.e., the center axis extending in the vertical direction). Therefore, the plurality of rods 12 in a concentrated state can be fed from the 2 nd holding hopper 40 toward the packaging bag 14. Further, since the plurality of rods 12 are held in the bottom portions 40b of the plurality of holding chambers 45 in a state of being close to each other, the difference in timing at which the rods 12 fall from the respective holding chambers 45 according to the opening and closing of the opening and closing unit 66 is small, and the rods 12 can be caused to fall from the plurality of holding chambers 45 toward the packaging bag 14 substantially simultaneously.
In addition, the configuration in which the plurality of holding chambers 45 are formed by partitioning the space by the partition body 43 (see the 2 nd holding hopper 40 shown in fig. 24 to 26 and the 2 nd holding hopper 40 shown in fig. 27 to 28) is advantageous in the following points, compared to the configuration in which the plurality of holding chambers 45 are formed by the plurality of cylindrical bodies 46 (see the 2 nd holding hopper 40 shown in fig. 29 to 30): the structure is simple, and a plurality of holding chambers 45 can be formed easily. On the other hand, the form in which the plurality of holding chambers 45 are formed by the plurality of cylindrical bodies 46 is advantageous in the following respects, compared to the form in which the plurality of holding chambers 45 are formed by partitioning the space by the partition body 43: since the size (for example, the cross-sectional diameter of the inner wall surface) of each holding chamber 45 can be determined according to the number and size of the corresponding storage chamber 25 and the predetermined rod-shaped objects 12 to be held, the extra space in each holding chamber 45 can be reduced, and the rod-shaped objects 12 can be held more stably.
The diameter of the top portion 40a, the diameter of the bottom portion 40b, the vertical length, the wall shape, and other dimensions and shapes of the holding chambers 45 are not particularly limited, and the dimensions and/or shapes may be different between the holding chambers 45. However, in order to appropriately guide the rod-shaped objects 12 from the corresponding storage chambers 25 to the respective storage holding chambers 45, the top portion 40a of each holding chamber 45 is preferably sized and shaped to cover all of the bottom portions 25b of the corresponding two or more or 1 storage chamber 25. In order to appropriately guide the stick-shaped articles 12 from the holding chambers 45 to the packaging bag 14, the bottom portions 40b of the plurality of holding chambers 45 preferably have a size, shape, and relative position such that the bottom portions 40b of all the holding chambers 45 for holding the stick-shaped articles 12 can be covered with the opening of the packaging bag 14.
Other modifications
The present invention is not limited to the above-described embodiments and modifications, and may include various modifications that can be conceived by those skilled in the art, and the effects exhibited by the present invention are not limited to the above-described matters. Therefore, various additions, modifications, and partial deletions can be made to the respective elements described in the claims and the description without departing from the technical spirit and scope of the present invention.
For example, the number of the storage chambers 25 included in the 1 st holding hopper 24 is not particularly limited. The specific structure of the door 28 is not particularly limited, and the door 28 may have any structure that can open and close the bottom 25b of each storage chamber 25 (particularly, each storage chamber 25 in which the rod-like object 12 is stored). The specific configuration of the opening and closing means 66 is not particularly limited, and the opening and closing means 66 may have any configuration that can open and close the bottom 40b of the 2 nd holding hopper 40.
In the loading machine 10, the transport containers 22 are opened downward in the vertical direction at the loading position P1 by turning the transport containers 22 over, but other opening mechanisms may be used for the transport containers 22. For example, each of the conveyance containers 22 may have an opening that opens downward in the vertical direction and a door mechanism that can open and close the opening, and the opening may be changed from the closed state to the open state by operating the door mechanism of the conveyance container 22 disposed at the drop position P1.
In the first holding hopper 24, although the plurality of storage chambers 25 (see fig. 3 and the like) are formed by a plurality of cylindrical bodies, a plurality of storage chambers 25 may be formed by dividing a single space by a partition (see reference numeral 43 in fig. 24 to 28).
The specific structure of the rod-like object 12 is not particularly limited, and the rod-like object 12 may be configured by a package in which an arbitrary object is housed in a package, or the rod-like object 12 may be configured by an object itself that does not include a package. The object stored in the package may be a single type of object or a plurality of types of objects. The object stored in the package may have any form, and the rod-shaped object 12 may be configured by a package in which, for example, a powder, a liquid, a gel, a solid, a gas, or an object having two or more forms of the above-described forms is stored in the package. The application of the rod-like object 12 is not particularly limited, but typically, the rod-like object 12 can be used in the fields of food, medicine, cosmetics, and agricultural chemicals.
