Description

Can badge manufacturing device and method

[0001] The present disclosure relates to a badge manufacturing device and a method executed by a control unit of the badge manufacturing device.

[0002] A can badge manufacturing device is known that produces can badges by placing a sheet with a printed image on a front member and crimping the front member and back member together (see, for example, Patent Document 1). This can badge manufacturing device includes a lower mold having a recess into which the front member fits, and a front member supply unit that supplies the front members. The front member supply unit includes a front member stocker that stacks and stores the front members vertically, a pusher that pushes the lowest front member in the front member stocker toward the lower mold, and a front member slope that guides the front member pushed by the pusher toward the lower mold.

[0003] The can badge manufacturing apparatus further includes a second lower mold having a second recess into which the backing material fits, and a backing material supply unit that supplies the backing material. The backing material supply unit includes a backing material stocker that vertically stacks and stores the backing materials, a second pusher that pushes the lowest backing material in the backing material stocker toward the second lower mold, and a backing material slope that guides the backing material pushed out by the second pusher toward the second lower mold.

[0004] WO 2024 / 116656

[0005] In the above-mentioned can badge manufacturing device, the front member pushed out by the pusher often passes through a front member slope and fits into a recess in the lower mold. However, due to manufacturing variations in the front member, the amount of movement of the front member pushed out by the pusher varies, and the front member may not fit into the recess in the lower mold. In this case, the front member and back member cannot be properly crimped, and the manufactured can badge will be defective.

[0006] In addition, the backing material pushed out by the second pusher often passes through the backing material slope and fits into the second recess of the second lower die. However, due to manufacturing variations in the backing material, the amount of movement of the backing material pushed out by the second pusher varies, and the backing material may not fit into the second recess of the second lower die. In this case, the front and backing materials cannot be properly crimped, and the produced can badge will be defective.

[0007] The present disclosure has been made in consideration of the above circumstances, and its purpose is to provide a means for reliably fitting a can member that constitutes a can badge into a recess in a lower mold.

[0008] (1) The can badge manufacturing device of the present disclosure comprises a lower mold having a recess into which a can member, which is one of the front and back members of a can badge, is fitted; a supply unit that accumulates the can members and supplies the accumulated can members toward the lower mold; a moving unit that moves the lower mold to a basic position, a crimping position, and another position different from the basic position and the crimping position; and a control unit that controls the supply unit and the moving unit, wherein the control unit causes the supply unit to supply the can member when the lower mold is located at the basic position, and then moves the lower mold to the moving unit so that the lower mold moves from the basic position to the other position and stops.

[0009] According to the above-mentioned can badge manufacturing device, by moving the lower mold between the basic position and another position, the lower mold and the can members supplied toward the lower mold can be shaken, and can members that are not fitted into the recesses of the lower mold can be reliably fitted into the recesses of the lower mold.

[0010] (2) The control unit may cause the moving unit to move the lower mold from the intermediate position back to the basic position after the lower mold has moved from the basic position to the other position.

[0011] (3) The can badge manufacturing apparatus may further include a stopper, and the moving unit may include a drive unit and a moving member that is driven by the drive unit and moves together with the lower mold, and the moving member may collide with the stopper when the lower mold is located in at least one of the basic position and the other position.

[0012] (4) The can member is the front member, and the can badge manufacturing device further includes a conveying unit that conveys a sheet to be superimposed on the front member, and the control unit may move the lower mold to the moving unit so that the lower mold returns to the basic position before the sheet conveyed by the conveying unit reaches above the basic position.

[0013] (5) The control unit may cause the moving unit to move the lower mold so that when the lower mold moves between the basic position and the other position, it moves at a faster speed than when the lower mold moves between the basic position and the crimping position.

[0014] (6) The moving section can move the lower mold between the basic position and the crimping position, and the other position may be located between the basic position and the crimping position.

[0015] (7) The other position may be a position closer to the basic position than the basic position or the crimping position.

[0016] (8) The method disclosed herein is a method executed by a control unit of a can badge manufacturing device that includes: a lower mold having a recess into which a can member, which is one of the front and back members of a can badge, is fitted; a supply unit that accumulates the can members and supplies the accumulated can members toward the lower mold; a moving unit that moves the lower mold to a basic position, a crimping position, and another position different from the basic position and the crimping position; and a control unit, and includes the steps of: when the lower mold is located at the basic position, causing the can members accumulated in the supply unit to be supplied toward the lower mold; and, after the can members have been supplied, moving the lower mold to the moving unit so that the lower mold moves from the basic position to the other position and stops.

[0017] According to the present disclosure, the can member that constitutes the can badge can be reliably fitted into the recess in the lower mold.

[0019] The following describes a can badge manufacturing device 1 according to an embodiment of the present disclosure. Note that the embodiment described below is merely an example of the present disclosure, and it goes without saying that the embodiment can be modified as appropriate without departing from the spirit and scope of the present disclosure.

[0020] 1 to 4, the can badge production device 1 includes a printing unit 10, a conveying unit 20, a cutting unit 30, a front member supply unit 40, a back member supply unit 50, a rotational movement unit 60, a crimping unit 70, a removal unit 80, a CPU 91, a memory unit 92, and a communication unit 93. In the following description, the up-down direction is defined based on the state in which the can badge production device 1 is installed and ready for use. Furthermore, the front-rear direction is defined with the side where the conveying unit 20 is located being the front. Furthermore, the left-right direction is defined when the can badge production device 1 is viewed from the front.

[0021] [Configuration of Can Badge 3] The can badge 3 produced by the can badge production device 1 has a disk shape as shown in FIG. 5(A). The can badge 3 is produced by crimping a metal front member 4 shown in FIG. 5(B) and a metal back member 5 shown in FIG. 5(C). The front member 4 and back member 5 are made of a magnetic material such as tin-plated steel sheet. The can badge 3 has a cross-sectional structure as shown in FIG. 5(D). In the can badge 3, the surface of the front member 4 is covered with a transparent film 6 and a white sheet 7. The peripheral portions of the transparent film 6 and the white sheet 7 are sandwiched between the peripheral portions of the crimped front member 4 and back member 5. The white sheet 7 is, for example, white paper.

[0022] When the can badge 3 is viewed from the front, the front member 4 is not visible, but the image printed on the transparent film 6 covering the front member 4 is visible. However, in the areas where no image is printed, the white sheet 7 is visible through the transparent film 6. The back member 5 may be provided with a through-hole (not shown) into which a fastener for the can badge 3 (such as a hook pin or safety pin) can be inserted.

[0023] The can badge 3 is produced in the can badge production device 1 by printing an image on a transparent film 6, and then stacking and crimping the transparent film 6 with the printed image, the white sheet 7, the front member 4, and the back member 5 in that order.

[0024] [Printing Unit 10] The printing unit 10 has a printing section 11 and a tray 12 (see FIGS. 1 and 4). Transparent film 6 before an image is printed and white sheets 7 are alternately stored in the tray 12. The transparent film 6 and white sheets 7 stored in the tray 12 are rectangular in shape. Note that the printing unit 10 may have a tray for storing the transparent film 6 and another tray for storing the white sheets 7.

[0025] As shown in Figure 4, the printing unit 10 is communicatively connected to an external device 100. The printing unit 11 receives an image to be printed on a transparent film 6 (hereinafter referred to as a print image) from the external device 100. Transparent film 6 stored in a tray 12 is supplied to the printing unit 11. The printing unit 11 prints the print image received from the external device 100 on the back side of the supplied transparent film 6, mirror-inverted. The transparent film 6 with the printed image is discharged outside the printing unit 10. White sheets 7 stored in the tray 12 are also supplied to the printing unit 11. The printing unit 11 does not print an image on the supplied white sheet 7, but discharges it as is outside the printing unit 10.

[0026] [Conveying Unit 20] The conveying unit 20 is disposed in front of the badge production apparatus 1, in a position covering the front discharge port through which the transparent film 6 and white sheet 7 are discharged from the printing unit 10 (see FIGS. 1 and 2). The conveying unit 20 includes a conveying motor 21 (see FIG. 4), multiple rollers (not shown), multiple sensors (not shown), and the like. The conveying unit 20 conveys the transparent film 6 and white sheet 7 discharged from the printing unit 10 upward and backward, until the leading edges of the transparent film 6 and white sheet 7 reach above the basic position P1 of the rotational movement unit 60. The conveying unit 20 configured in this manner conveys the transparent film 6 and white sheet 7 to be superimposed on the front member 4.

[0027] [Rotational Transfer Unit 60] As shown in Figure 6, the rotational transfer unit 60 has a rotational transfer motor 61, a rotary table 62, a first lower mold 63, a second lower mold 64, a stopper 65, and a rotation shaft 66. The rotational transfer motor 61 generates a driving force to rotate the rotary table 62. The rotary table 62 has a generally circular shape in a plan view. The first lower mold 63 and the second lower mold 64 are placed on the upper surface of the rotary table 62. The rotation shaft 66 is the axis of rotation of the rotary table 62. The rotation shaft 66 extends in the vertical direction. Hereinafter, with regard to the rotational transfer unit 60, a clockwise direction when viewed from above will be referred to as a "clockwise direction," and a counterclockwise direction when viewed from above will be referred to as a "counterclockwise direction."

[0028] A gear 67 is formed on half of the outer circumferential side surface of the rotary table 62. The gear 67 meshes with a gear (not shown) attached to the rotation shaft of the rotary movement motor 61. The rotary table 62 receives driving force from the rotary movement motor 61 through the gear 67 and rotates around a rotation shaft 66. The first lower mold 63 and the second lower mold 64 rotate together with the rotary table 62 around the rotation shaft 66 and move between a base position P1 and a crimping position P2. The rotary table 62 is driven by the rotary movement motor 61 and rotates together with the first lower mold 63 and the second lower mold 64.

[0029] The first lower die 63 has a recess 63a into which the front member 4 is fitted (see FIG. 8). The shape of the recess 63a follows the outer diameter of the front member 4. The second lower die 64 has a recess 64a into which the back member 5 is fitted (see FIG. 10). The shape of the recess 64a follows the outer diameter of the back member 5. The basic position P1 is the position where the front member 4 is fitted into the recess 63a of the first lower die 63, and is also the position where the back member 5 is fitted into the recess 64a of the second lower die 64. The crimping position P2 is a position point-symmetrical to the basic position P1 with respect to the rotation axis 66. The crimping position P2 is the position where the crimping portion 70 performs the crimping process on the front member 4 and the back member 5. When the first lower die 63 is located at the basic position P1, the second lower die 64 is located at the crimping position P2. When the first lower die 63 is located at the crimping position P2, the second lower die 64 is located at the base position P1.

[0030] The rotary table 62 has a semicircular guide groove 68 near its outer periphery. The guide groove 68 is formed clockwise from a position facing the rotary shaft 66 across the first lower die 63 to a position facing the rotary shaft 66 across the second lower die 64. A stopper 65 extending in the vertical direction is inserted into the guide groove 68. The stopper 65 is fixed in the guide groove 68 at a position closest to the crimping position P2.

[0031] The rotary table 62 rotates counterclockwise and stops when the end of the guide groove 68 closest to the second lower die 64 hits the stopper 65. At this time, the first lower die 63 is located at the base position P1, and the second lower die 64 is located at the crimping position P2 (see FIG. 12A). The rotary table 62 rotates clockwise and stops when the end of the guide groove 68 closest to the first lower die 63 hits the stopper 65. At this time, the first lower die 63 is located at the crimping position P2, and the second lower die 64 is located at the base position P1 (see FIG. 12D). The stopper 65 has the function of restricting the rotation range of the rotary table 62.

[0032] The amount of rotation of the rotary table 62 is adjusted, for example, by a method of appropriately determining in advance the drive current of the rotary movement motor 61. Alternatively, the amount of rotation of the rotary table 62 may be adjusted by a method of detecting the amount of rotation of the rotary movement motor 61 or the rotation position of the rotary table 62 and controlling the drive current of the rotary movement motor 61 in accordance with the detection result. The rotary movement unit 60 configured in this manner can move the first lower die 63 and the second lower die 64 between the base position P1 and the crimping position P2.

[0033] As will be described later, the rotational movement unit 60 moves the first lower mold 63 from the base position P1 to an intermediate position P3 (see FIG. 12 ) under control of the control unit 90. The intermediate position P3 is a position different from the base position P1 and the crimping position P2, and is located between the base position P1 and the crimping position P2. The rotational movement unit 60 moves the first lower mold 63 between the base position P1, the crimping position P2, and the intermediate position P3.

[0034] [Cutting Unit 30] The cutting unit 30 cuts the transparent film 6 and white sheet 7 conveyed by the conveying unit 20 to fit the shape of the can badge 3. As shown in FIG. 7A , the transparent film 6 before cutting has pre-formed cut lines 6c defining a circular portion 6a that matches the shape of the can badge 3, and pre-formed cut lines 6d connecting the cut lines 6c to one side of the transparent film 6. By cutting along the cut lines 6c and 6d, the transparent film 6 is cut into the circular portion 6a and a peripheral portion 6b. As shown in FIG. 7B , similar cut lines 7c and 7d are pre-formed on the white sheet 7 before cutting. By cutting along the cut lines 7c and 7d, the white sheet 7 is cut into the circular portion 7a and a peripheral portion 7b that match the shape of the can badge 3.

[0035] The cutting unit 30 includes a cutting motor 31, a pressure arm 32, a pressure head 33, and a collection box 34 (see FIGS. 3 and 4). The cutting motor 31 generates a driving force that rotates the pressure arm 32. The pressure arm 32 receives the driving force from the cutting motor 31 and rotates around a rotation axis (not shown). The pressure head 33 is connected to the tip of the pressure arm 32. The pressure head 33 moves between a standby position and a pressing position as the pressure arm 32 rotates. The standby position is a position where the pressure head 33 does not contact the transparent film 6 or the white sheet 7 on the first lower mold 63 located at the base position P1. The pressing position is a position where the pressure head 33 contacts the circular portion 6 a of the transparent film 6 or the circular portion 7 a of the white sheet 7 on the first lower mold 63 located at the base position P1.

[0036] When the pressing head 33 is in contact with the circular portion 6 a of the transparent film 6 at the pressing position, the conveying unit 20 conveys the transparent film 6 toward the collection box 34, whereby the transparent film 6 is cut along the cut lines 6 c and 6 d. As a result, the circular portion 6 a remains on the first lower die 63, and the peripheral portion 6 b is collected in the collection box 34.

[0037] When the pressing head 33 is in contact with the circular portion 7a of the white sheet 7 at the pressing position, the conveying unit 20 conveys the white sheet 7 toward the collection box 34, whereby the white sheet 7 is cut along the cut lines 7c and 7d. As a result, the circular portion 7a is left on the first lower die 63, and the peripheral portion 7b is collected in the collection box 34.

[0038] [Front member supply unit 40] The front member supply unit 40 is disposed to the rear right of the basic position P1 (see FIG. 3). As shown in FIGS. 8 and 9, the front member supply unit 40 has a front member supply motor 41, a front member stocker 42, a front member slope 43, and a front member pusher 44. The front member supply unit 40 accumulates front members 4 and supplies the accumulated front members 4 toward the first lower mold 63.

[0039] The front member supply motor 41 generates a driving force to move the front member pusher 44. The front member stocker 42 has a cylindrical shape that extends in the vertical direction. The inner shape of the horizontal cross section of the front member stocker 42 is a shape that follows the outer shape of the front members 4. The front member stocker 42 stacks and stores the front members 4 in the vertical direction. The lowest front member 4 among the front members 4 stored in the front member stocker 42 is located on a front member slope 43.

[0040] The front member slope 43 is an inclined path extending in the D1 direction shown in FIG. 8 . The front member slope 43 has a guide surface that guides the front member 4 toward the first lower mold 63 located at the basic position P1. Between the lower end of the front member stocker 42 and the guide surface of the front member slope 43, there is a gap that allows only one front member 4 to pass through. The front member pusher 44 is a flat member extending in the D1 direction. A rack gear 45 is formed on one longitudinal side of the front member pusher 44 (the front side in FIG. 8 ). The rack gear 45 meshes with a pinion gear 46 provided on the rotation shaft of the front member supply motor 41. The front member pusher 44 receives driving force from the front member supply motor 41 and reciprocates in the D1 direction on the guide surface of the front member slope 43. The amount of movement of the front member pusher 44 can be adjusted, for example, by suitably determining the drive current of the front member supply motor 41 in advance, or by detecting the amount of rotation of the front member supply motor 41 or the position of the front member pusher 44 and controlling the drive current of the front member supply motor 41 according to the detection results.

[0041] The front member pusher 44 abuts against the lowest front member 4 among the front member 4 stored in the front member stocker 42 and slides the front member 4 in the direction D1 on the guide surface of the front member slope 43. The front member 4 fits into the recess 63a of the first lower die 63 located at the basic position P1. Figure 9 shows the front member 4 sliding on the guide surface of the front member slope 43 before fitting into the recess 63a of the first lower die 63. Through the above operations, the front member supply unit 40 supplies the front members 4 one by one toward the first lower die 63.

[0042] [Back Material Supply Unit 50] The back material supply unit 50 is disposed to the left rear of the basic position P1 (see FIG. 3). As shown in FIG. 10, the back material supply unit 50 has a back material supply motor 51, a back material stocker 52, a back material slope 53, and a back material pusher 54. The back material supply unit 50 accumulates back materials 5 and supplies the accumulated back materials 5 toward the second lower mold 64.

[0043] The backing material supply motor 51 generates a driving force to move the backing material pusher 54. The backing material stocker 52 has a cylindrical shape that extends in the vertical direction. The inner shape of the horizontal cross section of the backing material stocker 52 is a shape that follows the outer shape of the backing materials 5. The backing material stocker 52 stores the backing materials 5 in a stacked manner in the vertical direction. The lowest backing material 5 among the backing materials 5 stored in the backing material stocker 52 is located on the backing material slope 53.

[0044] The back member slope 53 is an inclined path extending in the D2 direction shown in FIG. 10 . The back member slope 53 has a guide surface that guides the back member 5 toward the second lower mold 64, which is located at the basic position P1. Between the lower end of the back member stocker 52 and the guide surface of the back member slope 53, there is a gap large enough for only one back member 5 to pass through. The back member pusher 54 is a flat member extending in the D2 direction. A rack gear 55 is formed on one longitudinal edge of the back member pusher 54 (the rear edge in FIG. 10 ). The rack gear 55 meshes with a pinion gear (not shown) attached to the rotation shaft of the back member supply motor 51. The back member pusher 54 receives driving force from the back member supply motor 51 and reciprocates in the D2 direction on the guide surface of the back member slope 53. The amount of movement of the back member pusher 54 is adjusted in the same manner as the amount of movement of the front member pusher 44.

[0045] The back material pusher 54 contacts the lowest back material 5 among the back materials 5 stored in the back material stocker 52 and slides the back material 5 in the direction D2 on the guide surface of the back material slope 53. The back material 5 fits into the recess 64a of the second lower die 64, which is located at the basic position P1. Through the above operations, the back material supply unit 50 supplies the back materials 5 one by one toward the second lower die 64.

[0046] [Crimping Unit 70] The crimping unit 70 performs crimping processing at the crimping position P2. The crimping unit 70 has a crimping motor 71, an elevator device 72, and an upper die (not shown) (see FIGS. 3 and 4). The upper die is connected to the lower end of the elevator device 72. The crimping motor 71 generates a driving force to operate the elevator device 72. The elevator device 72 receives the driving force from the crimping motor 71 and moves the upper die in the vertical direction.

[0047] Before the crimping process, the upper die is in a raised position. When the first lower die 63, with the front member 4 fitted into the recess 63a, is positioned at crimping position P2, the upper die descends until it reaches the first lower die 63. At this time, the front member 4 fitted into the recess 63a of the first lower die 63 is released from the first lower die 63 and held by the upper die. Next, the upper die ascends while holding the front member 4. Next, the rotary table 62 rotates, and when the second lower die 64, with the back member 5 fitted into the recess 64a, is positioned at crimping position P2, the upper die descends until it reaches the second lower die 64. At this time, crimping is performed between the front member 4 held by the upper die and the back member 5 fitted into the recess 64a of the second lower die 64, completing the can badge 3. The completed can badge 3 is placed on the second lower die 64. The upper die then ascends.

[0048] [Removal Unit 80] The removal unit 80 performs the removal process of the badges 3 at the base position P1. The removal unit 80 includes a removal motor 81, a removal arm 82, a removal head 83, a seat 84, and a finished product storage box 85 (see Figures 3 and 4). The removal motor 81 generates a driving force that rotates the removal arm 82. The removal arm 82 receives the driving force from the removal motor 81 and rotates around a rotation axis (not shown). The removal head 83 is formed of a magnetic material and connected to the tip of the removal arm 82. The removal head 83 moves back and forth between a collection position and a removal position as the removal arm 82 rotates. The seat 84 is provided at the collection position. The seat 84 has an upper surface and a groove. The upper surface of the seat 84 is an inclined surface that slopes downward toward the finished product storage box 85. The groove of the seat 84 has an opening shape that can accommodate only the tip portion of the removal arm 82, including the removal head 83. The groove has a depth such that the take-out head 83 housed in the groove cannot magnetically attract the badge 3 on the seat 84 .

[0049] When the take-out head 83 is located at the take-out position, it approaches the second lower die 64, which is located at the basic position P1, and magnetically attracts the badge 3 placed on the second lower die 64. The take-out arm 82 rotates while the take-out head 83 still magnetically attracts the badge 3, causing the take-out head 83 to move to the collection position. At the collection position, the tip of the take-out arm 82, including the take-out head 83, is housed in the groove of the seat 84. The badge 3 abuts against the upper surface of the seat 84 and cannot enter the groove, so it separates from the take-out head 83. The badge 3 that has separated from the take-out head 83 slides down the upper surface of the seat 84 and is collected in a finished product storage box 85.

[0050] [Control Unit 90] As shown in Figure 4, the conveying unit 20, cutting unit 30, front member supply unit 40, back member supply unit 50, rotational movement unit 60, crimping unit 70, and removal unit 80 are controlled by a control unit 90 including a CPU 91 and a storage unit 92. The storage unit 92 is a memory such as a ROM or RAM. The storage unit 92 stores programs executed by the CPU 91, data used by the CPU 91, and the like. The CPU 91 controls the operation of each unit of the can badge production device 1 by executing the programs stored in the storage unit 92. The communication unit 93 is a communication interface circuit for communication between the control unit 90 and an external device 100.

[0051] [Operation of Control Unit 90] When the control unit 90 receives a can badge production instruction from the external device 100, it performs the operations shown in FIG. 11 . First, the control unit 90 controls the rotational movement unit 60 to move the first lower mold 63 to the base position P1 (S11). In S11, the control unit 90 controls the rotational movement motor 61 to rotate the turntable 62 counterclockwise so that the first lower mold 63 is at the base position P1 and the second lower mold 64 is at the crimping position P2 (see FIG. 12(A)). At this time, the end of the guide groove 68 closest to the second lower mold 64 collides with the stopper 65, causing the turntable 62 to a sudden stop. Note that if the first lower mold 63 is initially at the base position P1, the control unit 90 does not need to execute S11.

[0052] Next, the control unit 90 causes the front member supply unit 40 to supply the front member 4 toward the first lower mold 63 (S12). In S12, the control unit 90 drives the front member supply motor 41 to move the front member pusher 44 along the front member slope 43. The front member supply unit 40 supplies the front member 4 toward the first lower mold 63 located at the basic position P1, and the supplied front member 4 fits into the recess 63a of the first lower mold 63.

[0053] Next, the control unit 90 moves the first lower mold 63 to an intermediate position P3 (S13). In S13, the control unit 90 drives the rotary movement motor 61 to rotate the rotary table 62 clockwise so that the first lower mold 63 is located at the intermediate position P3 and stops at the intermediate position P3 (see FIG. 12B). The intermediate position P3 is a position between the base position P1 and the crimping position P2, and is a position rotated clockwise from the base position P1 by a predetermined angle θ1 around the rotation axis 66. The angle θ1 is, for example, an angle within a range of 15° to 20°. By the control unit 90 executing S13, the first lower mold 63 moves from the base position P1 to the intermediate position P3 and stops temporarily at the intermediate position P3.

[0054] The intermediate position P3 may be any position between the basic position P1 and the crimping position P2. However, it is preferable that the intermediate position P3 be closer to the basic position P1 than the crimping position P2. In particular, it is preferable that the intermediate position P3 is not too far from the basic position P1. Furthermore, high accuracy is not required for the intermediate position P3. For example, it does not matter if the intermediate position P3 in the actual machine is slightly different from the intermediate position at the time of design, and it does not matter if the intermediate position P3 in the actual machine fluctuates slightly.

[0055] When designing the can badge manufacturing device 1, the maximum protruding amount of the front member 4 that does not fit into the recess 63a of the first lower die 63 is predicted. The distance between the base position P1 and the intermediate position P3 is preferably equal to or greater than the predicted maximum protruding amount. With this configuration, the rotary table 62 rotates at least by the maximum protruding amount of the front member 4. Therefore, the protruding portion of the front member 4 is reliably fitted into the recess 63a of the first lower die 63.

[0056] Furthermore, when designing the can badge production device 1, the maximum protrusion angle (angle around the rotation axis 66) of the front member 4 that does not fit into the recess 63a of the first lower die 63 is predicted. The rotation angle around the rotation axis 66 between the base position P1 and the intermediate position P3 is preferably equal to or greater than the predicted maximum protrusion angle. With this configuration, the rotary table 62 rotates at least by the maximum protrusion angle of the front member 4. Therefore, the protruding portion of the front member 4 is reliably fitted into the recess 63a of the first lower die 63.

[0057] Next, the control unit 90 moves the first lower die 63 to the base position P1 (S14). In S14, the control unit 90 drives the rotational movement motor 61 to rotate the turntable 62 counterclockwise so that the first lower die 63 returns to the base position P1 and the second lower die 64 returns to the crimping position P2 (see FIG. 12C). At this time, the end of the guide groove 68 near the second lower die 64 collides with the stopper 65, and the turntable 62 suddenly stops.

[0058] Next, the control unit 90 conveys and cuts the white sheet 7 (S15). In S15, the control unit 90 drives the conveying motor 21 to cause the conveying unit 20 to convey the white sheet 7 discharged from the printing unit 10 to above the first lower die 63 located at the basic position P1. Note that no image is printed on the conveyed white sheet 7. Next, the control unit 90 drives the cutting motor 31 to bring the pressure head 33 into contact with the circular portion 7a of the white sheet 7, and then drives the conveying motor 21 to convey the white sheet 7 toward the collection box 34. As a result, the white sheet 7 is cut into the circular portion 7a and the peripheral portion 7b, and the circular portion 7a remains on the first lower die 63 located at the basic position P1.

[0059] Next, the control unit 90 conveys and cuts the transparent film 6 (S16). In S16, the control unit 90 drives the conveying motor 21 to cause the conveying unit 20 to convey the transparent film 6 discharged from the printing unit 10 to above the first lower die 63 located at the basic position P1. Note that an image is printed on the conveyed transparent film 6. Next, the control unit 90 drives the cutting motor 31 to abut the holding head 33 against the circular portion 6a of the transparent film 6, and then drives the conveying motor 21 to convey the transparent film 6 toward the collection box 34. As a result, the transparent film 6 is cut into the circular portion 6a and the peripheral portion 6b, and the circular portion 6a remains on the first lower die 63 located at the basic position P1. At this point, the circular portion 6a of the transparent film 6 and the circular portion 7a of the white sheet 7 are stacked, from top to bottom, on the front member 4 fitted into the recess 63a of the first lower die 63.

[0060] Next, the control unit 90 moves the first lower die 63 to the crimping position P2 and the second lower die 64 to the base position P1 (S17). In S17, the control unit 90 drives the rotational movement motor 61 to rotate the turntable 62 clockwise so that the first lower die 63 is at the crimping position P2 and the second lower die 64 is at the base position P1 (see FIG. 12(D)). At this time, the end of the guide groove 68 near the first lower die 63 collides with the stopper 65, and the turntable 62 suddenly stops.

[0061] Next, the control unit 90 holds the front member 4 in the upper mold of the crimping unit 70 (S18). In S18, the control unit 90 drives the crimping motor 71 to lower the upper mold until it reaches the first lower mold 63. As a result, the front member 4 is held in the upper mold of the crimping unit 70 with the transparent film 6 and the white sheet 7 overlapping each other.

[0062] Next, the control unit 90 causes the backing material supply unit 50 to supply the backing material 5 toward the second lower mold 64 (S19). In S19, the control unit 90 drives the backing material supply motor 51 to move the backing material pusher 54 along the backing material slope 53. The backing material supply unit 50 supplies the backing material 5 toward the second lower mold 64 located at the basic position P1, and the supplied backing material 5 fits into the recess 64a of the second lower mold 64. Note that the control unit 90 may execute S18 and S19 in the reverse order, or may execute S18 and S19 in parallel.

[0063] Next, the control unit 90 moves the second lower die 64 to the crimping position P2 (S20). In S20, the control unit 90 drives the rotary movement motor 61 to rotate the turntable 62 counterclockwise so that the first lower die 63 is at the base position P1 and the second lower die 64 is at the crimping position P2. At this time, the end of the guide groove 68 near the second lower die 64 collides with the stopper 65, and the turntable 62 suddenly stops. Note that the operation performed by the control unit 90 in S20 is the same as the operation performed by the control unit 90 in S11.

[0064] Next, the control unit 90 causes the crimping unit 70 to perform the crimping process (S21). In S21, the control unit 90 drives the crimping motor 71 to lower the upper die until it reaches the second lower die 64. This causes the front member 4 and the back member 5 to be crimped together with the transparent film 6 and the white sheet 7 stacked on top of the front member 4, completing the can badge 3. The can badge 3 is placed on the second lower die 64, which is located at crimping position P2.

[0065] Next, the control unit 90 moves the second lower die 64 to the base position P1 (S22). In S22, the control unit 90 drives the rotational movement motor 61 to rotate the turntable 62 clockwise so that the first lower die 63 is at the crimping position P2 and the second lower die 64 is at the base position P1. At this time, the end of the guide groove 68 near the first lower die 63 collides with the stopper 65, and the turntable 62 suddenly stops. Note that the operation performed by the control unit 90 in S22 is the same as the operation performed by the control unit 90 in S17.

[0066] Next, the control unit 90 causes the removal unit 80 to execute a removal process (S23). In S23, the control unit 90 drives the removal motor 81 to bring the removal head 83 close to the can badge 3 and magnetically attach the can badge 3 to the removal head 83. Next, the control unit 90 drives the removal motor 81 to bring the removal head 83 close to the finished product storage box 85 and collects the can badge 3 in the finished product storage box 85. By the control unit 90 performing the operations shown in Fig. 11, one can badge 3 is completed.

[0067] For the sake of convenience, the control unit 90 executes S15 after executing S14, i.e., conveys the white sheet 7 after the first lower die 63 returns to the home position P1. However, the control unit 90 can start conveying the white sheet 7 at an earlier timing. In order to properly overlay the white sheet 7 on the front member 4 fitted into the recess 63a of the first lower die 63, the first lower die 63 must return to the home position P1 before the white sheet 7 reaches above the home position P1. Therefore, the control unit 90 controls the rotational movement unit 60 to move the first lower die 63 so that the first lower die 63 returns to the home position P1 before the white sheet 7 conveyed by the conveying unit 20 reaches above the home position P1.

[0068] 12(A) to 12(D) show how the first lower mold 63 and the front member 4 rotate when the control unit 90 performs the operation shown in Fig. 12. When the control unit 90 executes S11 and S12, the rotary table 62 is in the state shown in Fig. 12(A). At this time, the first lower mold 63 and the front member 4 are located at the basic position P1.

[0069] When the control unit 90 executes S13, the rotary table 62 rotates clockwise by an angle θ1 to the state shown in Fig. 12(B). The first lower die 63 and the front member 4 move from the base position P1 to the intermediate position P3, and the second lower die 64 moves from the crimping position P2 to a position point-symmetrical to the intermediate position P3 with respect to the rotation axis 66.

[0070] When the control unit 90 executes S14, the rotary table 62 rotates counterclockwise by an angle θ1, and assumes the state shown in Fig. 12(C). The first lower die 63 and the front member 4 return from the intermediate position P3 to the basic position P1, and the second lower die 64 returns from a position point-symmetrical to the intermediate position P3 about the rotation axis 66 to the crimping position P2.

[0071] When the control unit 90 executes S17, the rotary table 62 rotates 180° clockwise to the state shown in Fig. 12(D). The first lower die 63 and the front member 4 move from the base position P1 to the crimping position P2, and the second lower die 64 moves from the crimping position P2 to the base position P1.

[0072] In this manner, the first lower mold 63 moves from the home position P1 to the intermediate position P3, returns from the intermediate position P3 to the home position P1, and then moves from the home position P1 to the crimping position P2. When moving the first lower mold 63 between the home position P1 and the crimping position P2, the control unit 90 drives the rotational movement motor 61 in a predetermined manner to rotate the turntable 62 at a predetermined speed. The movement speed of the first lower mold 63 at this time is designated V1. When moving the first lower mold 63 between the home position P1 and the intermediate position P3, the control unit 90 drives the rotational movement motor 61 in a different manner to rotate the turntable 62 at a different speed. The movement speed of the first lower mold 63 at this time is designated V2. It is preferable that the control unit 90 controls the rotational movement unit 60 to move the first lower mold 63 so that the movement speed V2 is faster than the movement speed V1. The reason for this is that it is desirable to complete the operation of moving the first lower die 63 between the basic position P1 and the intermediate position P3 as quickly as possible, since this operation is essentially unnecessary if the front member 4 is sure to fit into the recess 63a of the first lower die 63. However, depending on the configuration of the can badge production device, the moving speed V2 may be slower than the moving speed V1, or the two moving speeds V1 and V2 may be the same.

[0073] In most cases, the front member 4 pushed out by the front member pusher 44 passes through the front member slope 43 and fits into the recess 63a of the first lower die 63. However, due to manufacturing variations in the front member 4, the amount of movement of the front member 4 pushed out by the front member pusher 44 varies. For this reason, there are cases where the front member 4 does not fit into the recess 63a of the first lower die 63. In this case, unless special measures are taken, the front member 4 and the back member 5 cannot be properly crimped together, and the manufactured can badge 3 will be defective.

[0074] To solve this problem, in the can badge manufacturing device 1, the control unit 90 causes the front member 4 to be supplied from the front member supply unit 40 when the first lower die 63 is located at the basic position P1, and then causes the rotational movement unit 60 to move the first lower die 63 so that the first lower die 63 moves from the basic position P1 to the intermediate position P3 and stops there, and then moves from the intermediate position P3 to the basic position P1 and stops there.

[0075] When the first lower die 63 starts to move from the home position P1 toward the intermediate position P3, the first lower die 63 swings, and the front member 4 supplied toward the first lower die 63 also swings. In addition, when the first lower die 63 moves from the home position P1 to the intermediate position P3 and stops, the first lower die 63 swings, and the front member 4 supplied toward the first lower die 63 also swings. Similarly, when the first lower die 63 starts to move from the intermediate position P3 toward the home position P1, and when the first lower die 63 moves from the intermediate position P3 to the home position P1 and stops, the first lower die 63 swings, and the front member 4 supplied toward the first lower die 63 also swings. In particular, when the first lower die 63 moves from the intermediate position P3 to the home position P1 and stops, the rotary table 62 collides with the stopper 65 and stops suddenly, so the first lower die 63 is likely to swing, and the front member 4 supplied toward the first lower die 63 is also likely to swing. This allows the front member 4 that is not fitted into the recess 63a of the first lower die 63 to be fitted into the recess 63a of the first lower die 63. Therefore, a good can badge 3 can be produced using the front member 4 that is fitted into the recess 63a of the first lower die 63.

[0076] In the above description, the front member 4 is an example of a can member. The white sheet 7 is an example of a sheet. The front member supply unit 40 is an example of a supply unit. The rotational movement unit 60 is an example of a movement unit. The first lower mold 63 is an example of a lower mold. The intermediate position P3 is an example of another position. The rotational movement motor 61 is an example of a drive unit. The rotary table 62 is an example of a movement member.

[0077] [Operation and Effect of the Embodiment] As described above, the can badge production device 1 includes a first lower die 63 (lower die), a front member supply unit 40 (supply unit), a rotational movement unit 60 (movement unit), and a control unit 90 that controls the front member supply unit 40 and the rotational movement unit 60. When the first lower die 63 is located at the basic position P1, the control unit 90 causes the front member supply unit 40 to supply the front member 4 (S12). Thereafter, the control unit 90 causes the rotational movement unit 60 to move the first lower die 63 from the basic position P1 to an intermediate position P3 different from the basic position P1 and the crimping position P2, and stops there (S13).

[0078] In this way, the can badge producing apparatus 1 moves the first lower die 63 between the base position P1 and the intermediate position P3. Therefore, the can badge producing apparatus 1 can rock the first lower die 63 and the front member 4 supplied toward the first lower die 63, and can fit the front member 4 that is not fitted into the recess 63a of the first lower die 63 into the recess 63a of the first lower die 63.

[0079] Furthermore, after the first lower die 63 moves from the base position P1 to the intermediate position P3, the control unit 90 causes the rotational movement unit 60 to move the first lower die 63 so as to return from the intermediate position P3 to the base position P1 (S14). Therefore, when the first lower die 63 moves from the base position P1 to the intermediate position P3 and when the first lower die 63 returns from the intermediate position P3 to the base position P1, the first lower die 63 and the front member 4 supplied toward the first lower die 63 can be swung. Therefore, the front member 4 that is not fitted in the recess 63a of the first lower die 63 can be fitted into the recess 63a of the first lower die 63.

[0080] The can badge manufacturing apparatus 1 further includes a stopper 65, and the rotational movement unit 60 includes a rotational movement motor 61 (drive unit) and a rotary table 62 (moving member). The rotary table 62 collides with the stopper 65 when the first lower die 63 is located at the basic position P1. By causing the rotary table 62 to collide with the stopper 65 in this manner, an inertial force generated by the collision can be applied to the first lower die 63 and the front member 4 supplied toward the first lower die 63. Therefore, the front member 4 that is not fitted into the recess 63a of the first lower die 63 can be fitted into the recess 63a of the first lower die 63.

[0081] The can badge manufacturing apparatus 1 further includes a conveying unit 20. The control unit 90 controls the rotational movement unit 60 to move the first lower die 63 so that the first lower die 63 returns to the basic position P1 before the white sheet 7 (sheet) conveyed by the conveying unit 20 reaches above the basic position P1. By returning the first lower die 63 to the basic position P1 before the white sheet 7 reaches above the basic position P1, the sheet can be superimposed on the front member 4 fitted into the recess 63a of the first lower die 63.

[0082] Furthermore, the control unit 90 controls the rotational movement unit 60 to move the first lower die 63 at a faster speed when the first lower die 63 moves between the basic position P1 and the intermediate position P3 than when it moves between the basic position P1 and the crimping position P2. Because the first lower die 63 moves at a faster speed between the basic position P1 and the intermediate position P3 in this manner, the first lower die 63 and the front member 4 supplied toward the first lower die 63 can be greatly shaken. Therefore, the front member 4 that is not fitted into the recess 63a of the first lower die 63 can be fitted into the recess 63a of the first lower die 63.

[0083] Furthermore, the rotational movement unit 60 can move the first lower die 63 between the basic position P1 and the crimping position P2, and the intermediate position P3 is located between the basic position P1 and the crimping position P2. Therefore, the front member 4 that is not fitted into the recess 63a of the first lower die 63 can be fitted into the recess 63a of the first lower die 63 without expanding the range of movement of the first lower die 63.

[0084] Furthermore, the intermediate position P3 is the position closer to the basic position P1 than the crimping position P2. Therefore, by moving the first lower die 63 a short distance from the basic position P1, the front member 4 that is not fitted into the recess 63 a of the first lower die 63 can be fitted into the recess 63 a of the first lower die 63 in a short time.

[0085] The above description also discloses a method executed by the control unit 90 of the can badge manufacturing apparatus 1, which includes a step (S12) of supplying the surface material 4 accumulated in the surface material supply unit 40 toward the first lower mold 63 when the first lower mold 63 is located at the basic position P1, and a step (S13) of moving the first lower mold 63 to the rotational movement unit 60 so that after the surface material 4 has been supplied, the first lower mold 63 moves from the basic position P1 to an intermediate position P3 different from the basic position P1 and the crimping position P2 and stops there.

[0086] [Modifications] Various modifications can be made to the can badge manufacturing device 1 according to the embodiment. In the can badge manufacturing device 1, the turntable 62 collides with the stopper 65 and stops at a position where the first lower die 63 is located at the basic position P1 and at a position where the first lower die 63 is located at the crimping position P2. A can badge manufacturing device according to a modification may further include a stopper that moves up and down to stop the turntable 62 at a position where the first lower die 63 is located at the intermediate position P3.

[0087] The stopper 69 shown in FIG. 13 is inserted into the guide groove 68 of the rotary table 62. The horizontal position of the stopper 69 is a position rotated counterclockwise around the rotation axis 66 by an angle (180°-θ2) from the position of the stopper 65 (see FIG. 13(B)). The stopper 69 is connected to an elevator mechanism (not shown) and moves up and down between a retracted position and a contact position by the action of the elevator mechanism. The retracted position is a position lower than the rotary table 62 and is a position where there is no possibility of contact with the rotary table 62 (see FIG. 13(C)). The contact position is a position higher than the retracted position and is a position where there is a possibility of contact with the rotary table 62 (see FIG. 13(D)).

[0088] The control unit 90 retracts the stopper 69 to the retracted position except in S13 (FIG. 13(C)). At this time, the stopper 69 does not abut against the rotary table 62 and does not hinder the rotation of the rotary table 62 (see FIG. 13(A)). When the control unit 90 moves the first lower mold 63 to the intermediate position P3 in S13, it drives the lifting mechanism to raise the stopper 69 to the abutment position (FIG. 13(D)). At this time, the end of the guide groove 68 close to the first lower mold 63 collides with the stopper 69, and the rotary table 62 stops (FIG. 13(B)). The rotary table 62 abuts against the stopper 69 located at the abutment position and stops at the intermediate position P3.

[0089] The can badge manufacturing apparatus may include either stopper 65 or 69, or may include both stoppers 65 and 69. When first lower die 63 moves to at least one of base position P1 and intermediate position P3, turntable 62 may collide with stopper 65 or stopper 69 and stop.

[0090] In the can badge manufacturing apparatus 1, the control unit 90 moves the first lower die 63 between the base position P1 and the intermediate position P3 to fit the front member 4 into the recess 63a of the first lower die 63. In a can badge manufacturing apparatus according to a modified example, the control unit 90 may move the second lower die 64 (an example of a lower die) between the base position P1 and a second intermediate position P4 (an example of an intermediate position) to fit the back member 5 (an example of a can member) into the recess 64a of the second lower die 64. In this case, the control unit 90 performs the operation shown in FIG. 14. The flowchart shown in FIG. 14 is the flowchart shown in FIG. 11 with S31 and S32 added.

[0091] In S19, the control unit 90 controls the backing material supply unit 50 (an example of a supply unit) to supply a backing material toward the second lower mold 64. In FIG. 15A, the backing material 5 is fitted into the recess 64a of the second lower mold 64, which is located at the base position P1. Next, the control unit 90 moves the second lower mold 64 to a second intermediate position P4 (S31). In S31, the control unit 90 drives the rotational movement motor 61 to rotate the rotary table 62 counterclockwise so that the second lower mold 64 is located at the second intermediate position P4 (see FIG. 15B). The second intermediate position P4 is a position between the base position P1 and the crimping position P2, and is rotated counterclockwise from the base position P1 by a predetermined angle θ2 around the rotation axis 66. The angle θ2 may be the same as or different from the angle θ1. By the control unit 90 executing S31, the second lower mold 64 moves from the base position P1 to the second intermediate position P4 and stops temporarily at the second intermediate position P4.

[0092] Next, the control unit 90 moves the second lower die 64 to the base position P1 (S32). In S32, the control unit 90 drives the rotational movement motor 61 to rotate the turntable 62 clockwise so that the first lower die 63 returns to the crimping position P2 and the second lower die 64 returns to the base position P1 (see FIG. 15C). Next, in S20, the control unit 90 moves the second lower die 64 to the crimping position (see FIG. 15D).

[0093] With this type of can badge manufacturing device, by moving the second lower mold 64 between the basic position P1 and the second intermediate position P4, the second lower mold 64 and the backing material 5 supplied toward the second lower mold 64 are shaken, and the backing material 5 that is not fitted into the recess 64a of the second lower mold 64 can be fitted into the recess 64a of the second lower mold 64.

[0094] In the can badge manufacturing device according to the modified example, the control unit 90 may move the second lower die 64 between the basic position P1 and the second intermediate position P4 without moving the first lower die 63 between the basic position P1 and the intermediate position P3. In the can badge manufacturing device, the control unit 90 may move a lower die having a recess into which a can member, which is one of the front member 4 and the back member 5 of the can badge 3, between the basic position and the intermediate position.

[0095] In the can badge manufacturing device 1, the control unit 90 controls the rotational movement unit 60 to move the first lower die 63 from the base position P1 to the intermediate position P3 and then back to the base position P1. The intermediate position P3 is a position rotated clockwise by an angle θ1 from the base position P1 around the rotation axis 66. The clockwise direction is the rotational direction when the first lower die 63 moves from the base position P1 to the crimping position P2.

[0096] In a modified can badge manufacturing device, the control unit 90 may cause the rotational movement unit 60 to move the first lower die 63 so that the first lower die 63 moves from the base position P1 to the folding position P5 and then returns from the folding position P5 to the base position P1 (see FIG. 16 ). The folding position P5 is an angle obtained by rotating a predetermined angle θ3 counterclockwise from the base position P1 around the rotation axis 66. The counterclockwise rotation is the opposite direction to the rotational direction when the first lower die 63 moves from the base position P1 to the crimping position P2. The angle θ3 may be the same as or different from the angle θ1. The folding position P5 is an example of another position.

[0097] In the modified example shown in FIG. 16A , the rotary table 621 has a guide groove 681 that is longer than that of the rotary table 62 described above. The guide groove 681 extends clockwise from a position facing the rotary shaft 66 across the first lower mold 63 to a position facing the rotary shaft 66 across the second lower mold 64. The range in which the guide groove 681 is formed is (180 + θ3) / 360°. A gear (not shown) that meshes with a gear attached to the rotary shaft of the rotary movement motor 61 is formed on the outer peripheral side surface of the rotary table 621 beyond (180 + θ3) / 360°. When the rotary table 62 rotates counterclockwise and the end of the guide groove 68 closest to the second lower mold 64 collides with the stopper 65, the rotary table 62 stops. At this time, the first lower mold 63 is located at the turn-back position P5. The rotational movement unit 60 is capable of moving the first lower mold 63 between the basic position P1 and the crimping position P2, and is also capable of moving the first lower mold 63 between the basic position P1 and the folding position P5.

[0098] In this modification, after executing S11 and S12 shown in Fig. 11 , the control unit 90 drives the rotary movement motor 61 to rotate the turntable 62 counterclockwise so that the first lower mold 63 is positioned at the turn-back position P5 and stops at the turn-back position P5. Next, the control unit 90 drives the rotary movement motor 61 to rotate the turntable 621 clockwise so that the first lower mold 63 returns to the base position P1. Thereafter, the control unit 90 performs the operations from S15 onwards shown in Fig. 11 .

[0099] In the modified example shown in FIG. 16(B), the rotary table 622 has a circular shape in a plan view and does not have a guide groove. A gear (not shown) that meshes with a gear attached to the rotary shaft of the rotary movement motor 61 is formed on the outer circumferential side of the rotary table 622 at an angle of (180 + θ3) / 360 or more. The rotary movement unit 60 does not have a stopper, and the rotation range of the rotary table 622 is not restricted by a stopper. The rotary table 622 can rotate within the range of the gear formed on the outer circumferential side. In this modified example, the control unit 90 performs the same operation as in the modified example shown in FIG. 16(A).

[0100] 16(A) and 16(B) , similarly to the can badge production apparatus 1, the first lower die 63 and the front member 4 supplied toward the first lower die 63 can be shaken. Therefore, the front member 4 that is not fitted into the recess 63 a of the first lower die 63 can be fitted into the recess 63 a of the first lower die 63.

[0101] The can badge production apparatus 1 includes a rotational movement unit 60 as a movement unit that rotates and moves the first lower die 63 and the second lower die 64 between the base position P1 and the crimping position P2. A can badge production apparatus according to a modified example may include a linear movement unit that linearly moves the first lower die 63 and the second lower die 64 between the base position P1, the crimping position P2, and another position. Alternatively, a can badge production apparatus according to a modified example may include a movement unit that moves the first lower die 63 and the second lower die 64 along another path between the base position P1, the crimping position P2, and another position.
