[0037] <Can Product Manufacturing Apparatus>

[0038] Hereinafter, a can product manufacturing apparatus 100 using a loading jig 80 of a can member according to an embodiment of the present invention will be described with reference to the drawings. The loading jig 80 of the can member described below is merely one embodiment of the present invention. Therefore, the present invention is not limited to the following embodiments, and additions, deletions, and changes can be made without departing from the gist of the present invention. Figure 9A )

[0039] As Figure 1 and Figure 5B show, the can product manufacturing apparatus 100 is an apparatus for connecting (tightening) a front side member 11 laminated with a white film F and a printed medium W and a dorsal member 12 to manufacture a can product 10. Such a can product manufacturing apparatus 100 includes a printing unit 1, a conveying unit 2, a die unit 3, a front side member supply unit 4, a dorsal member supply unit 5, a pressing unit 6, a taking-out unit 7, a recycling box 8, a can product container 9, and a control device 110 ( Figure 3 )

[0040] As Figure 5A and Figure 5BAs shown in the example, the canned product 10 is, for example, a badge, which is made of a front-side member 11, a back-side member 12, a white film F, and a printed medium W. The front-side member 11 and the back-side member 12 are formed of a magnetic material such as tin-plated steel sheet, for example. The front-side member 11 has a front-side plate portion 11a that is circular when viewed from above and a circular front-side edge portion 11b that protrudes downward from the outer peripheral edge of the front-side plate portion 11a. The back-side member 12 has a back-side plate portion 12a that is circular when viewed from above and a circular back-side edge portion 12b that protrudes upward from the outer peripheral edge of the back-side plate portion 12a. It should be noted that the details of the back-side member 12 will be described later.

[0041] A covering portion Fb of the white film F is disposed on the surface of the front-side member 11, and a covering portion Wb of the printed medium W is disposed on the white film F. In the covering portions Wb and Fb, the portion protruding from the surface of the front-side plate portion 11a is bent downward from the outer peripheral edge of the front-side plate portion 11a to cover the surface of the front-side edge portion 11b. Further, the portion protruding from the surface of the front-side edge portion 11b is bent upward from the lower end of the front-side edge portion 11b and is clamped between the back surface of the front-side edge portion 11b and the back-side edge portion 12b of the back-side member 12. Then, in a state where the covering portions Wb and Fb are sandwiched between the opposing front-side edge portion 11b and back-side edge portion 12b, at least one of the front-side member 11 and the back-side member 12 is deformed (for example, tightened), thereby producing the canned product 10. It should be noted that the canned product 10 may also be made by covering the front-side member 11 only with the printed medium W without using the white film F.

[0042] As Figure 4A shown in the example, the printed medium W is a rectangular transparent sheet. The printed medium W has a downstream end We1 and an upstream end We2 in a first transport direction Dc1 when being transported by the transport unit 2 toward the die unit 3. The printed medium W includes: a covering portion Wb that covers the front-side member 11; a remaining portion Wa that is different from the covering portion Wb; a connecting portion Wc that connects the covering portion Wb and the remaining portion Wa; and a linear weak portion Wd that extends linearly from the connecting portion Wc to the downstream end We1. As Figure 4A and Figure 5BAs shown in the example, the covering portion Wb has: a first front-side portion Wf1 that covers the surface of the front-side plate portion 11a of the front-side member 11; a second front-side portion Wf2 that covers the surface of the front-side edge portion 11b; and a portion Wg to be clamped that is clamped between the back surface of the front-side edge portion 11b and the back-side edge portion 12b of the back-side member 12. The connecting portion Wc and the linear weak portion Wd are weak portions such as perforation lines that are less strong than the covering portion Wb and the remaining portion Wa. The connecting portion Wc and the linear weak portion Wd are cut by transporting the remaining portion Wa in the second transport direction Dc2 opposite to the first transport direction Dc1 by the transport unit 2 while the covering portion Wb is pressed by the pressing unit 6 in the die unit 3, thereby separating the covering portion Wb from the remaining portion Wa.

[0043] The structure of the white film F is substantially the same as the structure of the medium W to be printed. As Figure 4B shown in the example, the white film F is the same size as the medium W to be printed and is rectangular. The white film F has a downstream end Fe1, an upstream end Fe2, a covering portion Fb, a remaining portion Fa, a connecting portion Fc, and a linear weak portion Fd in the first transport direction Dc1. The downstream end Fe1 corresponds to the downstream end We1, the upstream end Fe2 corresponds to the upstream end We2, the covering portion Fb corresponds to the covering portion Wb, the remaining portion Fa corresponds to the remaining portion Wa, the connecting portion Fc corresponds to the connecting portion Wc, and the linear weak portion Fd corresponds to the linear weak portion Wd. It should be noted that the color of the white film F is not limited to white.

[0044] As Figures 1 to 3 shown in the example, the control device 110 of the canned product manufacturing apparatus 100 includes an interface 111 that exchanges data with an external device 114, an arithmetic unit 112 such as a CPU that processes data, and a storage unit 113 such as a memory that stores data. The control device 110 is connected to each part of the canned product manufacturing apparatus 100 via drive circuits 115 to 121 and controls the operation of each part.

[0045] The printing unit 1 is a printer such as an inkjet printer, a laser printer, or a thermal printer, and prints an image on the covering portion Wb of the medium W to be printed. The image is flipped so that it becomes a positive image when the user observes the image from the side of the medium W opposite to the side on which the image is printed. In this way, the printing unit 1 prints an image on the medium W to be printed and supplies it to the transport unit 2, and does not print an image on the white film F but supplies it to the transport unit 2.

[0046] The front-side member supply unit 4 includes a front-side member storage 40, a front-side member slider 43, a push rod 45, and a push rod motor 46. The front-side member storage 40 has a cylindrical shape and accommodates a plurality of front-side members 11 in a state of being stacked in the vertical direction. The front-side member slider 43 extends from a position below the front-side member storage 40 to the first lower die 30 disposed at the first die position P1 in the die unit 3. The push rod 45 reciprocates along the front-side member slider 43 by the push rod motor 46. Thus, the front-side member 11 descends from the front-side member storage 40 onto the front-side member slider 43 and is pressed by the push rod 45 toward the first lower die 30 and supplied to the first lower die 30.

[0047] The back-side member supply unit 5 includes a back-side member storage 50, a back-side member slider 53, a push rod 55, and a push rod motor 56. The back-side member storage 50 has: a cylindrical barrel 51; an upper opening 51a, which is an opening provided at the upper end of the barrel 51; a discharge port 51b from which the back-side member 12 is discharged; a slit 51c that extends along the central axis of the barrel 51 from the upper opening 51a and is formed in the barrel 51; and a pair of flanges 51d provided at both edges of the slit 51c. The back-side member 12 is loaded into the barrel 51 from the upper opening 51a and discharged from the discharge port 51b. The back-side member slider 53 extends from a position below the back-side member storage 50 to the second lower die 31 disposed at the first die position P1 in the die unit 3. The push rod 55 reciprocates on the upper surface of the back-side member slider 53 along the back-side member slider 53 by the push rod motor 56. The back-side member 12 descends from the back-side member storage 50 onto the back-side member slider 53 and is pushed by the push rod 55 toward the second lower die 31 and supplied to the second lower die 31. It should be noted that the details of the back-side member storage 50 will be described later.

[0048] The conveying unit 2 has a conveying motor 23, a driving roller Rk, and a driven roller Ro. The driving roller Rk sandwiches the printed medium W and the white film F between it and the driven roller Ro, and by rotating forward by the conveying motor 23, the printed medium W and the white film F are conveyed along the first conveying direction Dc1 above the front-side member 11 supported by the first lower die 30. On the other hand, by rotating the driving roller Rk in reverse by the conveying motor 23, the remaining part Wa of the printed medium W and the remaining part Fa of the white film F are conveyed along the second conveying direction Dc2 to the recycling box 8. Then, the remaining parts Wa and Fa are recycled as waste parts into the recycling box 8.

[0049] The pressing unit 6 includes a pressing motor 60, a remaining portion pressing head 65, and a pressing head 66. The remaining portion pressing head 65 and the pressing head 66 press the print medium W against the front side member 11 by means of the pressing motor 60. In this state, when the remaining portion Wa of the print medium W is transported in the second transport direction Dc2 by the transport unit 2, the connecting portion Wc and the linear weak portion Wd of the print medium W are cut, and the covering portion Wb is separated from the remaining portion Wa. The covering portion Wb remains above the front side member 11, and the remaining portion Wa is transported to the recycling bin 8 for recycling. In addition, regarding the white film F, similarly to the print medium W, the covering portion Fb is separated from the remaining portion Fa, the covering portion Fb remains above the front side member 11, and the remaining portion Fa is transported to the recycling bin 8 for recycling.

[0050] The die unit 3 includes a first lower die 30 that supports the front side member 11, a second lower die 31 that supports the back side member 12, a rotatably supported worktable 32, an upper die lifting motor 34, a lower die moving motor 35, and an upper die 33. The rotatably supported worktable 32 rotates the first lower die 30 and the second lower die 31 by means of the lower die moving motor 35, so that the first lower die 30 and the second lower die 31 are moved to the second die position P2 below the upper die 33 or the first die position P1 other than the second die position P2. The upper die 33 rises and falls by means of the upper die lifting motor 34.

[0051] The first lower die 30 arranges the front side member 11 at the first die position P1, and after arranging the covering portions Wb, Fb above it, it moves to the second die position P2 below the upper die 33. After the upper die 33 descends toward the first lower die 30 and presses the covering portions Wb, Fb against the front side member 11, it rises to separate the front side member 11 covered by the covering portions Wb, Fb from the first lower die 30. In addition, after the second lower die 31 arranges the back side member 12 at the first die position P1, it moves to the second die position P2 below the upper die 33. The upper die 33 descends toward the second lower die 31 to tighten the front side member 11 and the back side member 12 in such a manner that the clamped portions Wg, Fg of the covering portions Wb, Fb are sandwiched therebetween, thereby manufacturing the can product 10.

[0052] The taking-out unit 7 includes a taking-out motor 70, a swing arm 71, a magnet member 72, and a seat portion 73. The swing arm 71 is equipped with the magnet member 72 at its front end and rotates by means of the taking-out motor 70 so that the magnet member 72 moves between the second lower die 31 and the seat portion 73. By the rotation of the swing arm 71, after the magnet member 72 adheres to the can product 10 supported on the second lower die 31, the can product 10 is moved to the seat portion 73. The can product 10 slides down the sloping seat portion 73 into the can product container 9 and is stored in the can product container 9.

[0053] <Back side member>

[0054] The dorsal member 12 is supported by Figure 12 the support portion 81 of the filling jig 80 for the can member as shown in the example of, and is loaded into the dorsal member storage 50 of the can product manufacturing apparatus 100. Thus, as Figures 6A to 7B shown in the example of, an accessory 14 for supporting on the support portion 81 is assembled to the assembly surface 12c where the fixing member 13 is assembled on the dorsal member 12, and together with the accessory 14, a can member unit 15 is constituted. It should be noted that the directions parallel and intersecting (for example, orthogonal) to the assembly surface 12c are referred to as the longitudinal direction and the lateral direction. The direction orthogonal (for example, orthogonal) to the assembly surface 12c is referred to as the thickness direction. However, the arrangement of the dorsal member 12 is not limited to this. In addition, as the can member, the dorsal member 12 is described, but the can member is not limited to this, and for example, it may also be the front side member 11.

[0055] The dorsal member 12 has a dorsal plate portion 12a that is circular when viewed in the thickness direction and an annular dorsal edge portion 12b that projects from the edge of the dorsal plate portion 12a. For example, the dorsal edge portion 12b has a base end connected to the edge of the dorsal plate portion 12a and a front end with a diameter larger than the diameter of the base end. The dorsal plate portion 12a has a circular flat flat area 12a1 at its center and an annular inclined area 12a2 connected to the edge of the flat area 12a1 and the base end of the dorsal edge portion 12b. An assembly surface 12c is provided in the flat area 12a1, and the assembly surface 12c is arranged concentrically with the dorsal member 12. The inclined area 12a2 is inclined such that the front end of the dorsal edge portion 12b is on the extended surface of the flat area 12a1 in the thickness direction. Thus, the thickness of the dorsal member 12 is the dimension between the flat area 12a1 and the front end of the dorsal edge portion 12b and the base end of the dorsal edge portion 12b in the thickness direction.

[0056] The fixing member 13 is a member for fixing the can product 10 to a fixed portion such as clothes and bags. Hereinafter, a safety pin is described as the fixing member 13, but the fixing member 13 is not limited to this, and it may also be a magnet or the like. The pin 13a of the safety pin as the fixing member 13 is provided at an interval from the assembly surface 12c in the thickness direction and extends in the lateral direction.

[0057] The accessory 14 has a substrate 14a. The substrate 14a has a shape obtained by cutting a circle having the same or substantially the same size as the assembly surface 12c with a straight line extending in the lateral direction. The substrate 14a is in a flat plate shape, and one surface thereof faces the assembly surface 12c.

[0058] The accessory 14 has an insertion part 14b. The insertion part 14b is a flat plate shape orthogonal to the lateral direction. The proximal end in the thickness direction is connected to the substrate 14a, and a V-shaped recess is provided at its front end. One or more (two in this embodiment) insertion parts 14b are inserted between the substrate 14a and the needle 13a of the fixing member 13. Thereby, the substrate 14a and the insertion part 14b are clamped between the mounting surface 12c of the dorsal member 12 and the needle 13a of the fixing member 13 mounted on the dorsal member 12, and thus the accessory 14 is assembled to the dorsal member 12. In addition, by inserting the needle 13a into the recess of the insertion part 14b, the movement of the needle 13a is restricted by the insertion part 14b, so that noise and damage to the dorsal member 12 caused by the movement of the needle 13a can be reduced. Moreover, the plurality of insertion parts 14b are arranged at intervals with the center of the needle 13a clamped between them in the lateral direction, whereby the needle 13a is stably supported by the insertion parts 14b at a plurality of positions.

[0059] The accessory 14 has a rotation support part 14c and a gripping part 14d. The rotation support part 14c and the gripping part 14d are arranged at the center of the substrate 14a in the lateral direction. The rotation support part 14c is connected to one end of the substrate 14a in the longitudinal direction, and the gripping part 14d is connected to the other end of the substrate 14a. The rotation support part 14c has a curved surface that protrudes in the longitudinal direction away from the gripping part 14d when viewed along the lateral direction. For example, the rotation support part 14c has an inclined part 14c1 connected to the substrate 14a and an end part 14c2 connected to the inclined part 14c1. The inclined part 14c1 and the end part 14c2 are flat plate shapes extending in the lateral direction. When viewed along the lateral direction, the end part 14c2 is provided perpendicular to the substrate 14a, and the smaller angle formed by the inclined part 14c1 with the substrate 14a and the smaller angle formed by the inclined part 14c1 with the end part 14c2 are obtuse angles. The insertion part 14b is arranged in the space surrounded by the rotation support part 14c, the substrate 14a, and the first part 14f described later, and is connected to them. Thereby, the strength of the rotation support part 14c, the first part 14f, and the insertion part 14b is improved.

[0060] The gripping portion 14d extends linearly in the lateral direction. The further the gripping portion 14d is from the rotation support portion 14c in the longitudinal direction, the more it inclines away from the substrate 14a in the thickness direction and faces the inclined region 12a2 of the back member 12. The gripping portion 14d is gripped by the user, and the accessory 14 can rotate relative to the mounting surface 12c. During the rotation of the accessory 14, in a state where the insertion portion 14b abuts against the needle 13a at the recess and the rotation support portion 14c abuts against the mounting surface 12c, the gripping portion 14d moves between a close position close to the mounting surface 12c and a separation position farther from the mounting surface 12c than the close position. The close position is the position of the gripping portion 14d when the substrate 14a is parallel to the mounting surface 12c and abuts against the mounting surface 12c. The separation position is the position of the gripping portion 14d when the substrate 14a is inclined with respect to the mounting surface 12c and separated from the mounting surface 12c, and is farther from the mounting surface 12c than the close position in the thickness direction.

[0061] In a state where the insertion portion 14b is inserted between the mounting surface 12c and the needle 13a and the accessory 14 is mounted on the back member 12, by moving the gripping portion 14d between the close position and the separation position, the accessory 14 is supported by the rotation support portion 14c on the mounting surface 12c and rotates. Here, when the gripping portion 14d is at the close position, the inclined portion 14c1 of the rotation support portion 14c is inclined with respect to the mounting surface 12c, and the end portion 14c2 is provided perpendicular to the mounting surface 12c. As the gripping portion 14d moves from the close position to the separation position, the accessory 14 rotates, and the inclined portion 14c1 of the rotation support portion 14c becomes parallel to the mounting surface 12c and abuts against the mounting surface 12c. Thus, the end portion of the back member 12 and the gripping portion 14d abut against the contact surface A such as the floor, and it becomes a leg that supports the back member 12 in an upright state on the contact surface A. Therefore, the accessory 14 functions as a support for the can product 10 using the back member 12.

[0062] Moreover, when the attachment member 14 rotates such that the gripping portion 14d is farther from the mounting surface 12c than the separation position in the thickness direction, the end portion 14c2 of the rotation support portion 14c is parallel to the mounting surface 12c and abuts against the mounting surface 12c. As a result, the insertion portion 14b is disengaged from between the mounting surface 12c and the needle 13a, and the attachment member 14 is removed from the back member 12. Conversely, if the attachment member 14 is rotated while the insertion portion 14b is inserted between the mounting surface 12c and the needle 13a, the attachment member 14 is attached to the back member 12. In this way, the attachment member 14 can be attached to and detached from the back member 12. In addition, both ends of the gripping portion 14d are connected to a pair of connecting portions 14e. The connecting portion 14e protrudes from the substrate 14a in the thickness direction and extends between the end portions in the lateral direction of the gripping portion 14d and a second portion 14g described later. Since the gripping portion 14d is connected to the substrate 14a and the second portion 14g through the connecting portion 14e, the strength of the gripping portion 14d is increased.

[0063] The attachment member 14 has a first portion 14f and a second portion 14g. The first portion 14f and the second portion 14g are flat plates extending in the lateral direction and protrude from the substrate 14a in the thickness direction. In the longitudinal direction, the rotation support portion 14c, the first portion 14f, and the second portion 14g are arranged in sequence at intervals. The first portion 14f and the second portion 14g are arranged at a prescribed length apart in the longitudinal direction and are arranged parallel to each other. The first portion 14f and the second portion 14g sandwich the center 12d of the mounting surface 12c between them in the longitudinal direction, and the first portion 14f is closer to the center 12d than the second portion 14g. Therefore, the first distance L1 between the first portion 14f and the center 12d is smaller than the second distance L2 between the second portion 14g and the center 12d. As a result, when the support portion 81 having a width of a prescribed length or less in the longitudinal direction is inserted between the first portion 14f and the second portion 14g, the back member 12 is arranged offset with respect to the support portion 81 in the longitudinal direction.

[0064] The attachment member 14 has a third portion 14h. The third portion 14h is a flat plate extending in the longitudinal direction and protrudes from the substrate 14a in the thickness direction. The first portion 14f and the second portion 14g are arranged at the center of the mounting surface 12c in the lateral direction, whereas the third portion 14h is arranged on the side closer to the lateral direction than the center 12d of the mounting surface 12c. As a result, the third portion 14h is provided at a position separated from the center 12d of the mounting surface 12c by one side in the crossing direction that crosses the direction from the first portion 14f toward the second portion 14g. For example, the direction from the first portion 14f toward the second portion 14g is a direction that crosses (e.g., is orthogonal to) the direction in which the first portion 14f and the second portion 14g extend.

[0065] One end of the third part 14h in the longitudinal direction is connected to one end of the first part 14f in the transverse direction, and the other end of the third part 14h is connected to one end of the second part 14g in the transverse direction. Therefore, the first part 14f, the second part 14g, and the third part 14h are arranged in a U-shape. The space surrounded by the first part 14f, the second part 14g, and the third part 14h is used as an insertion space for the support portion 81 of the loading jig 80 to be inserted in the transverse direction. One side in the transverse direction of the insertion space is closed by the third part 14h, and the other side in the transverse direction is open. When the support portion 81 is inserted between the first part 14f and the second part 14g from the open portion, the extension line of the insertion path intersects the third part 14h.

[0066] It should be noted that, as shown in the examples of Figure 8A and Figure 8B , the accessory 14 may also have a hook 14i. In this case, the first part 14f has an L-shape. The first part 14f is connected to one of the two insertion portions 14b, extends longitudinally from the insertion portion 14b, and further bends to extend in the transverse direction away from the third part 14h. The portion extending in the transverse direction is arranged parallel to the second part 14g with a specified length separation in the longitudinal direction. When the support portion 81 of the loading jig 80 supports the back member 12, the support portion 81 is inserted between the first part 14f and the second part 14g arranged parallel to each other. In addition, the third part 14h is connected to the other insertion portion 14b of the two insertion portions 14b, extends longitudinally from the insertion portion 14b, and is connected to the second part 14g. When the support portion 81 is inserted between the first part 14f and the second part 14g arranged parallel to each other, the extension line of the insertion path intersects the third part 14h.

[0067] The hook 14i is connected to the rotation support portion 14c through the fixing portion 14j. One end of the fixing portion 14j is connected to the rotation support portion 14c, and the fixing portion 14j extends longitudinally from the rotation support portion 14c and passes between the needle 13a of the fixing member 13 and the mounting surface 12c. Moreover, after the fixing portion 14j protrudes in the thickness direction toward the direction away from the mounting surface 12c, the other end thereof is connected to the hook 14i. The hook 14i is in a flat plate shape and extends longitudinally toward the second portion 14g in a state parallel to the mounting surface 12c. The end portion of the hook 14i does not reach the second portion 14g and is spaced apart from the second portion 14g in the longitudinal direction. The hook 14i is disposed between the first portion 14f and the third portion 14h in the lateral direction. In the thickness direction, the hook 14i is disposed farther from the mounting surface 12c than the first portion 14f and the third portion 14h. Therefore, a gap is provided between the hook 14i and the first portion 14f and the third portion 14h. When the fixed portion is inserted into this gap, the fixed portion is clamped between the hook 14i and the first portion 14f and the third portion 14h, and the can product 10 including the dorsal member 12 is assembled to the fixed portion. In addition, in this case, the support portion 81 is inserted into the insertion space surrounded by the first portion 14f, the second portion 14g, the third portion 14h, the hook 14i, and the mounting surface 12c.

[0068] <Loading Fixture for Can Member>

[0069] As Figures 9A to 14 shown in the example of, the loading fixture 80 for the can member includes: an extension portion 84 that extends along a first direction; and a plurality of support portions 81 that protrude from the extension portion 84 in a second direction intersecting the first direction and are arranged at intervals along the first direction for supporting the dorsal member 12 in the interval. In addition, the loading fixture 80 for the can member includes a handle 86 that protrudes from the extension portion 84 in the second direction, and the extension portion 84 is located between the support portion 81 and the handle 86. Hereinafter, the loading fixture 80 for the can member will be described as a fixture for loading a plurality of dorsal members 12 into the cylindrical dorsal member storage 50 in the can product manufacturing apparatus 100 for manufacturing the can product 10 using the dorsal member 12. However, the loading fixture 80 is not limited thereto, and the dorsal member 12 can also be loaded into a member other than the dorsal member storage 50.

[0070] It should be noted that the first direction in which the extension portion 84 extends is referred to as the up-down direction. The direction in which the support portion 81 protrudes from the extension portion 84 in the second direction that intersects (e.g., is orthogonal to) the first direction is referred to as the front, and the direction opposite to the front in the second direction is referred to as the rear. That is, the second direction is referred to as the front-rear direction. The third direction that intersects (e.g., is orthogonal to) the first direction and the second direction is referred to as the left-right direction. However, the configuration of the loading jig 80 of the can member is not limited to this. In addition, the following description is that the slit 51c and the discharge port 51b of the back member reservoir 50 are located at the rear end of the cylindrical body 51 in accordance with the configuration of the loading jig 80, but the configuration of the back member reservoir 50 is not limited to this. Moreover, the following description is that the back member slider 53 extends rearward from a position below the back member reservoir 50 in accordance with the configuration of the back member reservoir 50, but the configuration of the back member slider 53 is not limited to this.

[0071] Specifically, the loading jig 80 includes an extension portion 84 and a plurality of support portions 81 that protrude forward from the extension portion 84. The loading jig 80 supports the back member 12 by the support portions 81, and inserts the back member 12 into the cylindrical body 51 from the upper opening 51a with the extension portion 84 sandwiched between a pair of flanges 51d, and then pulls out the support portions 81 out of the cylindrical body 51 through the slit 51c, thereby loading the back member 12 into the back member reservoir 50. The extension portion 84 and the support portions 81 are integrally formed of a resin such as polypropylene and polyethylene. Therefore, the loading jig 80 with a complex shape can be easily manufactured.

[0072] The extension portion 84 is, for example, in a substantially flat plate shape, extends in the up-down direction, and has a first wide portion 84a and a first narrow portion 84b. In the left-right direction, the width of the first wide portion 84a is constant in the up-down direction, smaller than the width of the slit 51c in the back member reservoir 50, and not more than the width of a pair of flanges 51d that sandwich the slit 51c therebetween. Therefore, when loading the back member 12 into the back member reservoir 50, the extension portion 84 moves along the flanges 51d between the pair of flanges 51d, so that the loading jig 80 can be easily moved.

[0073] The first narrow-width portion 84b is disposed below the first wide-width portion 84a, and its upper end is connected to the lower end of the first wide-width portion 84a. In the left-right direction, the width of the first narrow-width portion 84b is smaller than the width of the first wide-width portion 84a. The first narrow-width portion 84b has a first constant-width portion 84b1 and a first inclined portion 84b2. The first inclined portion 84b2 is disposed between the first wide-width portion 84a and the first constant-width portion 84b1 in the up-down direction, and the width in the left-right direction becomes smaller from the first wide-width portion 84a toward the first constant-width portion 84b1. The width of the first constant-width portion 84b1 in the left-right direction is constant in the up-down direction. When loading the dorsal member 12 into the dorsal member magazine 50, the first narrow-width portion 84b is inserted between a pair of flanges 51d before the first wide-width portion 84a, so it is easy to insert the extension portion 84 between the pair of flanges 51d. In addition, since there is no sharp corner in the extension portion 84 due to the first inclined portion 84b2, damage to the loading jig 80, the dorsal member magazine 50, etc. caused by the sharp corner can be reduced.

[0074] The extension portion 84 is connected to the protruding portion 85. The upper portion of the protruding portion 85 is connected to the lower end of the extension portion 84 and extends rearward from the extension portion 84, and the lower portion of the protruding portion 85 extends downward. The lower portion of the protruding portion 85 is a flat plate shape that intersects (e.g., is orthogonal to) the front-rear direction. In the up-down direction, the length of the protruding portion 85 is the same as or larger than the length of the discharge port 51b of the dorsal member magazine 50. Therefore, in a state where the extension portion 84 is inserted between a pair of flanges 51d, the protruding portion 85 faces the discharge port 51b. No supporting portion 81 is provided on the protruding portion 85, and a supporting portion 81 is provided on the extension portion 84 above the protruding portion 85. Thus, the dorsal member 12 supported by the supporting portion 81 is disposed above the discharge port 51b. Thereby, when the supporting portion 81 is pulled out from the slit 51c, the dorsal member 12 does not discharge from the discharge port 51b, but is caught by the two edges of the cylinder body 51 that sandwich the slit 51c having a width narrower than the diameter of the dorsal member 12, and thus remains inside the cylinder body 51.

[0075] The handle 86 is a flat plate shape that is long in the up-down direction, is disposed at the center of the extension portion 84 in the up-down direction and the left-right direction, and protrudes rearward from the rear surface of the extension portion 84. By a user gripping such a handle 86, it is easy to move the loading jig 80.

[0076] The upper and lower ends of the handle 86 are connected to the extension ribs 87. The extension ribs 87 are disposed at the center in the left - right direction of the extension portion 84 and project rearward from the rear surfaces of the extension portion 84 and the protruding portion 85. In the front - rear direction, the length of the extension rib 87 is shorter than the length of the handle 86. The extension rib 87 extends from the upper end of the handle 86 to the upper end of the extension portion 84, and further, from the lower end of the handle 86 to the lower end of the protruding portion 85. Thus, the extension rib 87 and the handle 86 extend in the up - down direction along the extension portion 84 and the protruding portion 85, and therefore, the strength of the extension portion 84 and the protruding portion 85 can be improved.

[0077] A plurality of support portions 81 are provided on the extension portion 84 and are arranged in a row at regular intervals in the up - down direction. The support portion 81 projects forward from the front surface of the extension portion 84. The support portion 81 has a flat support plate 82 and a support rib 83. The support rib 83 projects downward from the lower surface of the support plate 82 at the center in the left - right direction of the support plate 82 and extends in the front - rear direction over the entire length of the support plate 82. The strength of the support plate 82 can be improved by this support rib 83.

[0078] The interval between the support portions 81 adjacent to each other in the up - down direction is the interval between the upper surface of the support plate 82 and the lower surface of the support rib 83 opposed to the upper surface. The thickness of the dorsal member 12 in the up - down direction is equal to or less than the interval between the support portions 81. When the dorsal member 12 is filled into the interval between the support portions 81, it is clamped between the support plate 82 of the lower support portion 81 and the support rib 83 of the upper support portion 81 and is supported by the upper support portion 81 and the lower support portion 81. Thus, by simply filling the dorsal member 12 into the interval between the support portions 81, the dorsal member 12 can be easily supported by the support portions 81 of the loading jig 80.

[0079] The support plate 82 has a second wide - width portion 82a and a second narrow - width portion 82b. The second wide - width portion 82a is closer to the extension portion 84 than the second narrow - width portion 82b in the front - rear direction, and the front end of the second wide - width portion 82a is connected to the rear end of the second narrow - width portion 82b. The width of the second wide - width portion 82a in the left - right direction is equal to or less than the interval between the first part 14f and the second part 14g of the can member unit 15, and the support portion 81 is inserted into the insertion space between the first part 14f and the second part 14g. The width of the second narrow - width portion 82b in the left - right direction is smaller than that of the second wide - width portion 82a and becomes smaller toward the front. Therefore, when filling the dorsal member 12 into the interval between the support portions 81, since the second narrow - width portion 82b is inserted into the insertion space of the can member unit 15 before the second wide - width portion 82a of the support portion 81, it is easy to insert the support portion 81 into the insertion space.

[0080] Thus, when filling the dorsal member 12 into the interval between the support portions 81, the front - rear direction misalignment of the dorsal member 12 can be suppressed. Specifically,Figure 10A In the example of Figure 10A , in the front - rear direction, the first part 14f and the second part 14g of the can member unit 15 are closer to the extension part 84 than the third part 14h. In this case, when the support part 81 is inserted into the insertion space from between the first part 14f and the second part 14g toward the third part 14h, the support part 81 is located between the first part 14f and the second part 14g, and the front end of the support part 81 faces the opposing surface of the third part 14h. In contrast, as shown in Figure 10B the example of Figure 10B , in the front - rear direction, the first part 14f and the second part 14g are farther from the extension part 84 than the third part 14h. In this case, the support part 81 is not inserted into the insertion space between the first part 14f and the second part 14g, and the front end of the support part 81 faces the surface opposite to the opposing surface of the third part 14h. The third part 14h is arranged in the front - rear direction at a position offset from the center 12d of the mounting surface 12c of the back member 12 toward one side, and the center 12d is arranged between the first part 14f and the second part 14g. Therefore, compared with the length of the back member 12 protruding forward from the front end of the support part 81 in the case of Figure 10A , in the case of Figure 10B the length of the back member 12 protruding forward from the front end of the support part 81 is longer. Therefore, it is possible to prevent the user from filling the back member 12 into the space of the loading jig 80 with the front - rear direction reversed.

[0081] In addition, when filling the back member 12 into the space of the support part 81, it is possible to prevent the back member 12 from being misaligned in the up - down direction. Specifically, in the examples of Figure 10A and Figure 11A , the support part 81 is inserted between the first part 14f and the second part 14g with the mounting surface 12c of the back member 12 facing downward. In contrast, in the example of Figure 11B , the support part 81 is inserted between the first part 14f and the second part 14g with the mounting surface 12c of the back member 12 facing upward. The first part 14f is closer to the center 12d of the mounting surface 12c than the second part 14g in the left - right direction. Therefore, the back member 12 with the mounting surface 12c facing upward as in Figure 11B is offset to the left from the support part 81 compared with the back member 12 with the mounting surface 12c facing downward as in Figure 11A . Therefore, it is possible to prevent the user from filling the back member 12 into the space of the loading jig 80 with the up - down direction reversed.

[0082] The length of the support portion 81 in the front - rear direction is shorter than the inner diameter of the cylindrical body 51 of the dorsal member magazine 50. Further, the width of the support portion 81 in the left - right direction is smaller than the width of the first wide portion 84a of the extension portion 84 and the width of the slit 51c of the dorsal member magazine 50, and is equal to or less than the width of the first narrow portion 84b of the extension portion 84. In contrast, the diameter of the dorsal member 12 supported by the support portion 81 is larger than the width of the slit 51c of the dorsal member magazine 50. Therefore, when loading the dorsal member 12 into the dorsal member magazine 50, the extension portion 84 can be disposed outside the cylindrical body 51, and the support portion 81 protruding from the extension portion 84 can pass through the slit 51c, whereby the dorsal member 12 supported by the support portion 81 is inserted into the cylindrical body 51. Then, with the dorsal member 12 remaining in the cylindrical body 51, the support portion 81 can be pulled out of the cylindrical body 51 through the slit 51c.

[0083] The shape of the upper - end support portion 81 provided at the upper end of the extension portion 84 among the plurality of support portions 81 may also be different from that of the other support portions 81. That is, when filling the spaces between the support portions 81 with the dorsal members 12, the other support portions 81 are inserted into the insertion space of the can member unit 15, but the upper - end support portion 81 is not inserted into the insertion space. Therefore, the upper - end support portion 81 may be a rectangle with a width that is constant in the front - rear direction and is larger than the width of the insertion space between the first portion 14f and the second portion 14g. In this case, the upper - end support portion 81, like the other support portions 81, has a width smaller than the width of the slit 51c of the dorsal member magazine 50, and thus can be pulled out of the cylindrical body 51 through the slit 51c. It should be noted that the upper - end support portion 81 may also have a second narrow portion 82b like the other support portions 81.

[0084] <Dorsal member magazine>

[0085] As Figures 12 to 16 shown in the example, the dorsal member magazine 50 includes a cylindrical body 51 having a central axis extending in the up - down direction. The cylindrical body 51 has an upper opening 51a, a discharge port 51b, a slit 51c, a pair of flanges 51d, and a pusher port 51e. The inner diameter of the cylindrical body 51 and the diameter of the upper opening 51a are slightly larger than the diameter of the dorsal member 12. Therefore, the dorsal member 12 is inserted into the cylindrical body 51 from the upper opening 51a in such a manner that the fitting surface 12c of the dorsal member 12 is orthogonal to the central axis of the cylindrical body 51, and a plurality of dorsal members 12 are stacked and accommodated in the cylindrical body 51.

[0086] In the cylindrical body 51, as Figure 16As shown in the example, a plurality of tank member units 15 are stacked in such a manner that the accessory member 14 is located below the dorsal member 12. In the accessory member 14, in the vertical direction, the dimensions of the rotation support portion 14c and the second portion 14g are equal to each other, and are larger than the dimensions of other portions such as the first portion 14f and the third portion 14h. Further, in the vertical direction, the dimensions of the rotation support portion 14c and the second portion 14g are larger than the dimension of the fixing member 13. Therefore, the rotation support portion 14c and the second portion 14g of the upper tank member unit 15 support the dorsal member 12 on the lower dorsal member 12. In this way, between the dorsal members 12 adjacent to each other in the vertical direction, the accessory member 14 constitutes a spacer, and the dorsal members 12 can be stacked parallel to each other within the cylindrical body 51.

[0087] As Figures 12 to 16 shown in the example, the slit 51c is an opening extending downward from the upper opening 51a at the rear end of the cylindrical body 51. A pair of flanges 51d project rearward from both edges of the cylindrical body 51 sandwiching the slit 51c therebetween. The pair of flanges 51d are provided parallel to each other and are provided over the entire length of the slit 51c in the vertical direction. By forming the flanges 51d integrally with the cylindrical body 51, the strength of the cylindrical body 51 can be improved.

[0088] The discharge port 51b is an opening communicating with the slit 51c at the rear end of the cylindrical body 51. The height of the discharge port 51b in the vertical direction is greater than the height of the dorsal member 12, and the width of the discharge port 51b in the left-right direction is greater than the diameter of the dorsal member 12. Further, the pusher port 51e is an opening opposed to the discharge port 51b at the front end of the cylindrical body 51. The pusher 55 reciprocates inside and outside the cylindrical body 51 through the pusher port 51e. The pusher 55 moves rearward, pushing the dorsal member 12 inside the cylindrical body 51 to discharge it from the discharge port 51b. On the other hand, when the pusher 55 moves forward and retreats outside the cylindrical body 51, the dorsal member 12 inside the cylindrical body 51 descends between the discharge port 51b and the pusher port 51e.

[0089] An installation portion 51f is connected to the lower end of such a cylindrical body 51. The installation portion 51f extends downward from the cylindrical body 51 between the discharge port 51b and the pusher port 51e. By inserting the installation portion 51f into the installation hole 53a of the dorsal member slider 53, the cylindrical body 51 is installed on the dorsal member slider 53 and is disposed on the upper surface of the dorsal member slider 53.

[0090] <Method of loading tank members>

[0091] The method of loading the can member is a method of loading a plurality of back members 12 into a cylindrical back member reservoir 50 in a can product manufacturing apparatus 100 that manufactures a can product 10 using a back member 12, using a loading jig 80. The back member reservoir 50 has: a cylindrical barrel 51; an upper opening 51a provided at the upper end of the barrel 51; and a slit 51c that extends along the central axis from the upper opening 51a and is formed in the barrel 51. By inserting the loading jig 80 into the barrel 51 from the upper opening 51a with one end of the first direction of the extension portion 84 first, the back member 12 supported by the support portion 81 is located inside the barrel 51 and the extension portion 84 is located outside the barrel 51. Then, from this state, the loading jig 80 is moved through the slit 51c so that the support portion 81 goes outside the barrel 51, thereby removing the loading jig 80 from the barrel 51 and leaving the back member 12 inside the barrel 51.

[0092] Specifically, as shown in the example of Figure 12 , the user fills the space between the loading jig 80 with a plurality of back members 12, holds the handle 86 of the loading jig 80, and makes the first narrow portion 84b lower than the first wide portion 84a of the extension portion 84. Then, the user inserts the back member 12 supported by the support portion 81 into the barrel 51 from the upper opening 51a in such a manner that the extension portion 84 is disposed outside the barrel 51 and the support portion 81 protruding from the extension portion 84 passes through the slit 51c.

[0093] Then, as shown in the example of Figure 13 , the user disposes the extension portion 84 between a pair of flanges 51d, aligns the extension portion 84 with the slit 51c, and moves the loading jig 80 downward. As a result, the protruding portion 85 below the extension portion 84 abuts against the floor or the like, and the user stops the downward movement of the loading jig 80. Here, since the uppermost support portion 81 in the loading jig 80 is disposed below the upper end of the barrel 51, the back member 12 supported by the support portion 81 is housed inside the barrel 51. In addition, the protruding portion 85 faces the discharge port 51b of the back member reservoir 50. Since the support portion 81 is provided in the extension portion 84 disposed above the protruding portion 85, the back member 12 supported by the support portion 81 is surrounded by the barrel 51 around it at a position above the discharge port 51b.

[0094] Here, as shown in the example of Figure 14 , when the user moves the loading jig 80 backward, the support portion 81 is pulled out of the barrel 51 through the slit 51c. In contrast, the back member 12 is fixed to the inner surface of the barrel 51 and remains inside the barrel 51. In this way, the back member 12 is loaded into the back member reservoir 50.
