Summary of the Invention

Problems to be Solved by the Invention

[0006] Here, when the packaging material is thin or the diameter of the article to be packaged is large, the ears are likely to sag. If chrysanthemum folding is performed in this state, the finish may deteriorate.

[0007] The present invention has been made to solve the above problems, and an object of the present invention is to provide a packaging system capable of improving the finish of chrysanthemum folding.

Means for Solving the Problems

[0008] The packaging system according to the present invention includes a chrysanthemum folding device for folding the ear part of the packaging material and a chrysanthemum folding assisting device for assisting the chrysanthemum folding of the ear part. The packaging material has an outer peripheral surface packaging part that covers the outer peripheral surface of a columnar or cylindrical article to be packaged and an ear part that protrudes from the end surface of the article to be packaged, and the outer peripheral surface packaging part and the ear part are formed in a cylindrical shape. The chrysanthemum folding assisting device is configured to form a plurality of fold lines in the ear part before the chrysanthemum folding by the chrysanthemum folding device. The plurality of fold lines are arranged at intervals in the circumferential direction and are formed so as to extend in the axial direction of the article to be packaged.

[0009] By configuring in this way, the plurality of fold lines can make it difficult for the ear part to droop.

[0010] In the above packaging system, the chrysanthemum folding assisting device may include a plurality of fold line forming parts arranged at intervals in the circumferential direction. The fold line forming part has a receiving part extending in the axial direction and a pressing part rotatably provided on the receiving part. The receiving part has a gap and is configured to support the ear part from the radially inner side. The pressing part is configured to advance and retreat with respect to the gap of the receiving part by being rotated, and the ear part is sandwiched between the receiving part and the pressing part, so that a fold line is formed in the ear part.

[0011] In this case, the chrysanthemum fold assisting device includes a first moving mechanism for moving a plurality of crease forming parts. The first moving mechanism has a first plate and a second plate that are rotatably provided. On the first plate, a plurality of linear holes extending in the radial direction are formed at intervals in the circumferential direction. On the second plate, a plurality of curved holes that are arcuately curved are formed at intervals in the circumferential direction. The receiving parts of the plurality of crease forming parts are respectively fitted with corresponding linear holes and curved holes. When the first plate is rotated, the receiving parts of the plurality of crease forming parts are rotated, and when the second plate is rotated relative to the first plate, the receiving parts of the plurality of crease forming parts are respectively configured to move radially along the linear holes.

[0012] In this case, the chrysanthemum fold assisting device includes an operating mechanism for operating a plurality of crease forming parts. The operating mechanism has a third plate provided so as to rotate together with the first plate. The third plate is engaged with a pressing part and is configured to be axially movable. When the third plate is located on the side closer to the first plate, the pressing part faces radially outward, and when the third plate is located on the side farther from the first plate, the pressing part is configured to face axially and be disposed in the gap of the receiving part.

[0013] In the above packaging system, the chrysanthemum folding device includes a plurality of folding parts arranged at intervals in the circumferential direction. When the plurality of folding parts are moved radially inward near the end face of the article to be packaged, ears are folded toward the end face side of the article to be packaged, and folds are formed between adjacent folding parts. When the plurality of folding parts are rotated, the folds may be configured to fall toward the end face side of the article to be packaged.

[0014] In this case, the chrysanthemum folding device includes a second moving mechanism that moves a plurality of folding parts. The second moving mechanism has a fourth plate and a fifth plate that are rotatably provided. The fourth plate has a plurality of linear holes extending in the radial direction at intervals in the circumferential direction, and the fifth plate has a plurality of curved holes curved in an arc shape at intervals in the circumferential direction. The plurality of folding parts are respectively fitted with corresponding linear holes and curved holes. When the fourth plate is rotated, the plurality of folding parts are rotated, and when the fifth plate is rotated relative to the fourth plate, the plurality of folding parts are configured to be moved radially along the linear holes.

[0015] In this case, the folding part may be configured to push in the crease of the ear part.

Advantages of the Invention

[0016] According to the packaging system of the present invention, it is possible to improve the finish of the chrysanthemum fold.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, an embodiment of the present invention will be described.

[0019] First, with reference to FIGS. 1 and 2, the outline of the packaging system 100 according to this embodiment will be described.

[0020] The packaging system 100 is configured to package the winding roll 160 using the packaging material 150. The winding roll 160 (see FIG. 2) is formed in a cylindrical shape and has a hollow winding core 161 and a belt-like sheet 162 wound around the winding core 161. The packaging material 150 is, for example, a sheet-like member made of paper. Note that the winding roll 160 is an example of the "article to be packaged" of the present invention.

[0021] As shown in FIG. 1, the packaging system 100 includes a winding device (not shown), a pleat assisting device 1, a pleating device 2, and a conveying device 3. The conveying device 3 is configured to convey the take-up roll 160 in the order of the winding device, the pleat assisting device 1, and the pleating device 2. That is, the conveying device 3 is provided to send the take-up roll 160 in the conveying direction (Dc direction). The winding device is configured to wind the packaging material 150 around the outer circumference of the take-up roll 160.

[0022] Here, as shown in FIG. 2, the packaging material 150 wound by the winding device is formed in a cylindrical shape so as to cover the outer circumferential surface of the take-up roll 160, and both end portions in the circumferential direction are joined. Specifically, the packaging material 150 has an outer circumferential surface packaging portion 151 that covers the outer circumferential surface of the take-up roll 160 and an ear portion (margin portion) 152 that protrudes from the end surface of the take-up roll 160. The outer circumferential surface packaging portion 151 and the ear portion 152 are formed in a cylindrical shape, and the ear portion 152 is formed so as to extend continuously from both end portions in the axial direction (X direction) of the outer circumferential surface packaging portion 151.

[0023] As shown in FIG. 1, the pleat assisting device 1 and the pleating device 2 are provided as a pair on the left and right so as to face each other in the direction (X direction) orthogonal to the conveying direction. For this reason, while the pleat assisting device 1 and the pleating device 2 on one side perform processing on the ear portion 152 on one side, the pleat assisting device 1 and the pleating device 2 on the other side perform processing on the ear portion 152 on the other side.

[0024] The pleat assisting device 1 is configured to form a plurality of creases 152a (see FIG. 10) in the ear portion 152 before the pleating (gathering) by the pleating device 2. With the plurality of creases 152a, it is possible to make the ear portion 152 less likely to droop. That is, the pleat assisting device 1 is provided to assist the pleating of the ear portion 152. The pleating device 2 is configured to pleat the ear portion 152 of the packaging material 150. That is, the pleating device 2 is configured to form an end surface packaging portion 153 (see FIG. 16) of the packaging material 150 that covers the end surface of the take-up roll 160 by folding the ear portion 152.

[0025] -Chrysanthemum folding assisting device- Next, with reference to FIGS. 3 to 10, the chrysanthemum folding assisting device 1 of the present embodiment will be described.

[0026] A take-up roll 160 around which a packaging material 150 is wound by a winding device is supplied to the chrysanthemum folding assisting device 1. As shown in FIG. 3, the chrysanthemum folding assisting device 1 includes a plurality (for example, 12) of crease forming portions 11, a moving mechanism 12 for moving the plurality of crease forming portions 11, and an operating mechanism 13 for operating the plurality of crease forming portions 11. In FIGS. 3 and the like, only a part of the plurality of crease forming portions 11 is shown for easy viewing. Further, the moving mechanism 12 is an example of the "first moving mechanism" of the present invention.

[0027] The plurality of crease forming portions 11 are arranged at intervals in the circumferential direction around an air cylinder 132 described later. Each crease forming portion 11 has a receiving portion 111 and a pressing portion 112 which are long plate-like bodies, and the pressing portion 112 is rotatably provided on the receiving portion 111. Then, when an ear portion 152 is sandwiched between the receiving portion 111 and the pressing portion 112, a crease 152a is formed in the ear portion 152.

[0028] The receiving portion 111 is formed to extend in the axial direction (X direction) of the air cylinder 132. The receiving portion 111 has a gap 111a (see FIG. 6) and is configured to support the ear portion 152 from the radially inner side. A clamping roller 111b and a fitting roller 111c are provided on the proximal end side of the receiving portion 111.

[0029] The pressing portion 112 is configured to move forward and backward with respect to the gap 111a of the receiving portion 111 by being rotated by the operating mechanism 13. A rotation shaft 112a and an engagement roller 112b are provided on the proximal end side of the pressing portion 112. The pressing portion 112 is rotatably attached to the receiving portion 111 via the rotation shaft 112a.

[0030] The moving mechanism 12 includes plates 121 and 122, a motor 123 which is a power source for rotating the plate 121, and a motor 124 which is a power source for rotating the plate 122. The plates 121 and 122 are rotatably provided on a cylinder main body 132a described later. The plates 121 and 122 are arranged adjacent to each other, and the plate 121 is arranged on the side of the conveying device 3 with respect to the plate 122. In addition, an encoder (not shown) for detecting the rotation of the plate 121 is provided, and an encoder (not shown) for detecting the rotation of the plate 122 is provided. Note that the plates 121 and 122 are examples of the "first plate" and the "second plate" of the present invention, respectively.

[0031] As shown in FIG. 4, a plurality of linear holes 121a extending in the radial direction are formed in the plate 121 at intervals in the circumferential direction. A plurality of curved holes 122a curved in an arc shape are formed in the plate 122 at intervals in the circumferential direction. The plurality of curved holes 122a are formed in a spiral shape. For example, 12 linear holes 121a and curved holes 122a are provided so as to correspond to the crease forming portions 11, respectively. The corresponding linear holes 121a and curved holes 122a are arranged so as to intersect when viewed from the axial direction (X direction).

[0032] Then, the receiving portion 111 of the corresponding crease forming portion 11 is inserted (fitted) into the linear hole 121a of the plate 121, and the plate 121 is clamped by the clamping roller 111b of the receiving portion 111. The clamping roller 111b is configured to be rollable along the surface of the plate 121 beside the linear hole 121a. Therefore, the receiving portion 111 of the crease forming portion 11 is assembled to the plate 121 so as to be movable along the linear hole 121a. Accordingly, when the plate 121 is rotated, the receiving portions 111 of the plurality of crease forming portions 11 are rotated.

[0033] Further, a fitting roller 111c of the receiving portion 111 of the corresponding crease forming portion 11 is fitted into the curved hole 122a of the plate 122. The fitting roller 111c is configured to be rollable along the curved hole 122a within the curved hole 122a. Therefore, when the plate 122 is rotated with respect to the plate 121 and the intersecting position of the curved hole 122a with respect to the straight hole 121a changes, the receiving portions 111 of the plurality of crease forming portions 11 are each moved radially along the straight hole 121a. Note that when the plates 121 and 122 are integrally rotated, the receiving portions 111 of the plurality of crease forming portions 11 are rotated without being moved radially. That is, it is also possible to rotate while maintaining the radial position of the crease forming portion 11.

[0034] As shown in FIG. 3, the operating mechanism 13 includes a plate 131 and an air cylinder 132 that is a power source for moving the plate 131 in the axial direction (X direction). In the chrysanthemum fold assisting device 1, the axial direction of the air cylinder 132 is oriented to face the axial direction of the winding roll 160. Note that the plate 131 is an example of the "third plate" of the present invention.

[0035] The air cylinder 132 includes a cylinder body 132a, a piston 132b that is movable within the cylinder body 132a, and a piston rod 132c that is connected to the piston 132b. The cylinder body 132a is configured to be movable with respect to the winding roll 160. A plate 131 is rotatably assembled to the tip of the piston rod 132c.

[0036] The plate 131 is connected to the plate 121 and is provided to rotate together with the plate 121. The plate 131 is disposed adjacent to the plate 121 and is disposed on the conveyance device 3 side with respect to the plate 121.

[0037] As shown in FIG. 5, a plurality of straight holes 131a extending in the radial direction are formed in the plate 131 at intervals in the circumferential direction. The straight holes 131a reach the outer end portion in the radial direction of the plate 131, and the outer end portion in the radial direction is open. The straight holes 131a are arranged to correspond to the straight holes 121a, and for example, 12 straight holes 131a are provided. An engaging groove 131b extending in the radial direction is formed on the inner surface of the straight hole 131a. That is, the straight hole 131a is formed to penetrate the plate 131 in the thickness direction, and the engaging groove 131b is provided in a part of the plate 131 in the thickness direction.

[0038] As shown in FIG. 6, the receiving portion 111 of the corresponding fold forming portion 11 is inserted into the straight hole 131a of the plate 131. The engaging roller 112b of the pressing portion 112 is engaged with the engaging groove 131b. The engaging roller 112b is configured to be rollable along the engaging groove 131b within the engaging groove 131b.

[0039] Then, as shown in FIG. 3, when the piston rod 132c of the air cylinder 132 is retracted and the plate 131 is positioned closer to the plate 121, the pressing portion 112 is directed radially outward. On the other hand, as shown in FIG. 8, when the piston rod 132c of the air cylinder 132 protrudes and the plate 131 is positioned farther from the plate 121, the pressing portion 112 faces the axial direction (X direction) and is arranged in the gap 111a (see FIG. 9) of the receiving portion 111.

[0040] [Operation of the Chrysanthemum Fold Assist Device] In the chrysanthemum fold assist device 1, for example, a plurality of fold forming portions 11 are arranged at the innermost in the radial direction. Then, when the winding roll 160 around which the packaging material 150 is wound is supplied, the cylinder body 132a is moved closer to the winding roll 160, so that as shown in FIG. 3, the receiving portion 111 of the fold forming portion 11 is inserted inside the ear portion 152.

[0041] Then, as the plate 122 is rotated by the motor 124, the crease forming portion 11 is moved radially outward as shown in FIG. 7. The amount of movement of the crease forming portion 11 at this time is set according to the diameter of the ear portion 152. For this reason, the ear portion 152 is supported by the receiving portion 111 from the radially inner side. For example, the diameter of the ear portion 152 is preset, and the motor 124 is driven so that a virtual circle connecting the radially outer ends of the plurality of receiving portions 111 has the same diameter as the ear portion 152.

[0042] Next, as the piston rod 132c of the air cylinder 132 protrudes and the plate 131 is moved toward the winding roll 160, the pressing portion 112 is rotated about the rotation axis 112a as a fulcrum as shown in FIGS. 8 and 9. For this reason, the pressing portion 112 enters the gap 111a of the receiving portion 111, and the ear portion 152 supported by the receiving portion 111 is pressed by the pressing portion 112. That is, the ear portion 152 is sandwiched between the receiving portion 111 and the pressing portion 112.

[0043] Thereafter, with the ear portion 152 sandwiched between the pressing portion 112 and the receiving portion 111, the cylinder body 132a is moved away from the winding roll 160. As a result, the pressing portion 112 and the receiving portion 111 that sandwich the ear portion 152 are pulled out from the ear portion 152. For this reason, as shown in FIG. 10, a crease 152a is formed in the ear portion 152.

[0044] - Chrysanthemum folding device - Next, with reference to FIGS. 11 to 16, the chrysanthemum folding device 2 of the present embodiment will be described.

[0045] The chrysanthemum folding device 2 is configured to be supplied with the winding roll 160 in which the fold line 152a is formed on the ear part 152 by the chrysanthemum folding auxiliary device 1. As shown in FIG. 11, the chrysanthemum folding device 2 includes a plurality (for example, 12) of folding parts 21, a moving mechanism 22 for moving the plurality of folding parts 21, a plurality (for example, 12) of support rods 23, and a pushing mechanism 24. In FIG. 11 and the like, for the sake of clarity, only a part of the plurality of folding parts 21 and support rods 23 is shown, and the fold line 152a of the ear part 152 is not shown. Further, the moving mechanism 22 is an example of the "second moving mechanism" of the present invention.

[0046] The plurality of folding parts 21 are arranged at intervals in the circumferential direction around an air cylinder 242 described later. The folding part 21 has an arm 211, a folding plate 212, and a guide rod 213. The arm 211 is formed to extend in the axial direction (X direction) of the air cylinder 242. A clamping roller 211a and a fitting roller 211b are provided on the base end side of the arm 211. The folding plate 212 is attached to the tip of the arm 211 and is formed in an isosceles triangle shape when viewed from the axial direction. The folding plate 212 is arranged such that the apex angle faces the radially inner side. The guide rod 213 is attached to the apex angle of the folding plate 212 and is formed to extend in the axial direction. The guide rod 213 is arranged on the same side as the arm 211 with respect to the folding plate 212.

[0047] The moving mechanism 22 has plates 221 and 222, a motor 223 which is a power source for rotating the plate 221, and a motor 224 which is a power source for rotating the plate 222. The plates 221 and 222 are rotatably provided on a cylinder main body 242a described later. The plates 221 and 222 are arranged adjacent to each other, and the plate 221 is arranged on the side of the conveying device 3 with respect to the plate 222. Further, an encoder (not shown) for detecting the rotation of the plate 221 is provided, and an encoder (not shown) for detecting the rotation of the plate 222 is provided. The plates 221 and 222 are examples of the "fourth plate" and "fifth plate" of the present invention, respectively.

[0048] As shown in FIG. 12, a plurality of straight holes 221a extending in the radial direction are formed in the plate 221 at intervals in the circumferential direction. A plurality of curved holes 222a curved in an arc shape are formed in the plate 222 at intervals in the circumferential direction. The plurality of curved holes 222a are formed in a spiral shape. For example, twelve straight holes 221a and curved holes 222a are provided so as to correspond to the folding portions 21, respectively. The corresponding straight holes 221a and curved holes 222a are arranged so as to intersect when viewed from the axial direction (X direction).

[0049] Then, the arm 211 of the corresponding folding portion 21 is inserted (fitted) into the straight hole 221a of the plate 221, and the plate 221 is clamped by the clamping roller 211a of the arm 211. The clamping roller 211a is configured to be rollable along the surface of the plate 221 beside the straight hole 221a. For this reason, the arm 211 of the folding portion 21 is assembled to the plate 221 so as to be movable along the straight hole 221a. Therefore, when the plate 221 is rotated, the arms 211 of the plurality of folding portions 21 are rotated accordingly.

[0050] Further, the fitting roller 211b of the arm 211 of the corresponding folding portion 21 is fitted into the curved hole 222a of the plate 222. The fitting roller 211b is configured to be rollable along the curved hole 222a within the curved hole 222a. For this reason, when the plate 222 is rotated relative to the plate 221 and the intersecting position of the curved hole 222a with respect to the straight hole 221a changes, the arms 211 of the plurality of folding portions 21 are each moved radially along the straight hole 221a. When the plates 221 and 222 are integrally rotated, the arms 211 of the plurality of folding portions 21 are rotated without being moved radially. That is, it is also possible to rotate while maintaining the radial position of the folding portion 21.

[0051] A plurality of support rods 23 are arranged at circumferential intervals around the air cylinder 242. The support rods 23 are attached to the outer edge of the plate 221 and are alternately arranged with the folding portions 21 in the circumferential direction. As shown in FIG. 11, the support rods 23 are rotatable and are provided so as to incline radially inward from the outer edge of the plate 221.

[0052] The pushing mechanism 24 includes a pushing piece 241 and an air cylinder 242 which is a power source for moving the pushing piece 241 in the axial direction (X direction). In the corrugating device 2, the axial direction of the air cylinder 242 is oriented in the axial direction of the winding roll 160. The air cylinder 242 has a cylinder body 242a, a piston 242b movable within the cylinder body 242a, and a piston rod 242c connected to the piston 242b. The cylinder body 242a is configured to be movable relative to the winding roll 160. The pushing piece 241 is attached to the tip of the piston rod 242c.

[0053] [Operation of the corrugating device] In the corrugating device 2, for example, a plurality of folding portions 21 are arranged on the outermost side in the radial direction. When a winding roll 160 having a crease 152a formed in the ear portion 152 is supplied, the cylinder body 242a is moved closer to the winding roll 160, so that as shown in FIG. 11, the support rod 23 is inserted inside the ear portion 152 and the folding portion 21 is arranged outside the ear portion 152. At this time, the tip side (open end side) of the ear portion 152 is supported by the support rod 23, and the folding plate 212 is arranged near the end face of the winding roll 160. Further, the apex angle of the folding plate 212 is arranged at a position corresponding to the crease 152a. That is, the support rod 23 is arranged between the creases 152a in the circumferential direction.

[0054] Then, as the plate 222 is rotated by the motor 224, as shown in FIGS. 13 and 14, the folding portion 21 is moved radially inward. For this reason, the folding plate 212 causes the ear portion 152 to be folded toward the end face side of the winding roll 160 while forming fold lines between adjacent folding plates 212. At the start of folding, the apex angle of the folding plate 212 abuts against the fold line 152a of the ear portion 152, and folding is performed starting from the fold line 152a. Further, before the movement of the folding portion 21 radially inward is completed, the support rod 23 comes out from inside the ear portion 152 and returns to its original state. Note that the plurality of folding portions 21 are moved to the innermost position in the radial direction, and the rotation amount of the motor 224 at that time is preset.

[0055] Next, as the plates 221 and 222 are integrally rotated by the motors 223 and 224, the folding plates 212 of the folding portion 21 are rotated, and the fold lines are laid down toward the end face side of the winding roll 160. Thereby, the ear portion 152 is folded, and an end face packaging portion 153 (see FIG. 16) of the packaging material 150 covering the end face of the winding roll 160 is formed.

[0056] Thereafter, as the piston rod 242c of the air cylinder 242 protrudes, as shown in FIG. 15, the pushing piece 241 is pushed into the core 161. For this reason, the pushing piece 241 pushes the radially inner end portion of the end face packaging portion 153 of the packaging material 150 inside the core 161.

[0057] -Effect- In the present embodiment, as described above, since the ear portion 152 is provided with the fold line 152a by providing the chrysanthemum folding assisting device 1, it is possible to make the ear portion 152 less likely to droop. Thereby, since the deviation of the ear portion 152 when the ear portion 152 is folded by the folding plate 212 in the chrysanthemum folding device 2 is suppressed, it is possible to improve the finish of the chrysanthemum folding. Note that the packaging system 100 is particularly suitable when the packaging material 150 is thin or when the diameter of the winding roll 160 is large.

[0058] In addition, in the present embodiment, the folding plate 212 is moved radially inward near the end face of the winding roll 160, so that folding is performed near the base of the ear part 152. As a result, compared with the conventional case where the folding plate approaches the end face of the winding roll while folding the ear part by the folding plate, the vicinity of the base of the ear part 152 (the radially outer part in the end face packaging part 153 after the chrysanthemum fold) is easier to align. Thus, the finish of the chrysanthemum fold can also be improved by this means.

[0059] In addition, in the present embodiment, by the apex angle of the folding plate 212 pushing in the fold line 152a of the ear part 152, it is possible to easily fold the ear part 152 using the fold line 152a.

[0060] In addition, in the present embodiment, by providing the fold line forming part 11 having the receiving part 111 and the pressing part 112, it is possible to easily form the fold line 152a in the ear part 152.

[0061] In addition, in the present embodiment, by providing the moving mechanism 12 including the plate 121 having the linear hole 121a and the plate 122 having the curved hole 122a, a plurality of fold line forming parts 11 can be moved radially and rotated simultaneously. In addition, the position of the fold line forming part 11 can be adjusted according to the diameter of the ear part 152, and it can correspond to ear parts 152 with different diameters.

[0062] In addition, in the present embodiment, by providing the operating mechanism 13 including the plate 131 engaged with the pressing part 112, a plurality of pressing parts 112 can be rotated simultaneously.

[0063] In addition, in the present embodiment, by providing the moving mechanism 22 including the plate 221 having the linear hole 221a and the plate 222 having the curved hole 222a, a plurality of folding parts 21 can be moved radially and rotated simultaneously.

[0064] In addition, in the present embodiment, since the support rod 23 is provided, when the folding by the folding plate 212 is performed, the ear portion 152 is supported by the support rod 23, so that the folding creases can be formed with high precision.

[0065] In addition, in the present embodiment, since the guide rod 213 is provided, when the folding by the folding plate 212 is performed, the ear portion 152 can be prevented from falling outward in the radial direction.

[0066] -Other Embodiments- It should be noted that the embodiments disclosed this time are illustrative in all respects and are not a basis for restrictive interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-described embodiments, but is defined based on the description in the claims. In addition, the technical scope of the present invention includes all modifications within the meaning and scope equivalent to the claims.

[0067] For example, in the present embodiment, an example is shown in which the cylinder body 132a is moved away from the winding roll 160 with the ear portion 152 sandwiched between the pressing portion 112 and the receiving portion 111. However, the present invention is not limited to this, and after the sandwiching of the ear portion by the pressing portion and the receiving portion is released, the cylinder body may be moved away from the winding roll.
