Description

The present invention relates to a parts loading device for a badge manufacturing machine, and in particular to a device designed to facilitate assembly and disassembly.

For example, Patent Document 1 discloses a conventional can badge manufacturing device. The accessory manufacturing device described in Patent Document 1 manufactures can badges that are made up of an upper material, a lower material to which a safety pin is attached, a pattern backing that is placed on the front side of the upper material, and a cover film that is placed on the upper side of the pattern backing.

The accessory manufacturing device has a plate rotatably mounted on a base plate, and two receiving mold assemblies are mounted on both ends of the plate. The receiving mold assembly is composed of a base, a slide mounted on the base so that it can move up and down within a predetermined range, and a spring inserted between the slide and the base. The upper material, the pattern mount, and the cover film are placed on the slide of one receiving mold assembly in a layered state, and the lower material is placed on the slide of the other receiving mold assembly. The slide is approximately cylindrical, and the base is disposed inside.

The accessory manufacturing device includes a stamping die assembly consisting of a ram that can be moved up and down and has a piston at its tip, and a cylinder that can be moved up and down on the ram. The cylinder is hollow and opens downward, and the upper end of the slide has a step with which the lower end of the cylinder engages, and a tapered surface that is inclined toward the inside of the step is formed. The piston is disposed within the cylinder and can move up and down relatively within the cylinder. A protrusion is formed on the upper side of the piston of the ram, and the up and down movement of the cylinder is restricted by the protrusion and the piston. The accessory manufacturing device also includes a switching member, and by inserting this switching member between the upper end side of the cylinder and the protrusion of the ram, the cylinder can be fixed in a state where it is moved to the lower end side. Two posts are erected on the plate, and when the plate is rotated, these posts move the switching member, so that the state of the cylinder and the piston can be switched depending on the orientation of the plate.

When manufacturing the can badges, first, the plate is rotated, and the receiving die assembly on which the upper material, the pattern mount and the cover film are laminated in order is moved to below the pressing die assembly, so that the switching member is interposed between the upper end side of the cylinder and the protrusion of the ram.
Next, when the pressing die assembly is lowered, the slide of the receiving die assembly is pressed down by the cylinder. At this time, since the piston portion has moved to the upper end side of the cylinder, the tip side of the base is inserted into the cylinder, and the outer edges of the upper material, the pattern mount, and the cover film are folded by the cylinder and the base.

The die assembly is then raised so that the top material, the pattern mount and the cover film are held inside the cylinder with their outer edges folded over.
Next, the plate is rotated, the receiving die assembly on which the lower material is placed is moved to below the pressing die assembly, and the switching member is retracted from between the upper end side of the cylinder and the protrusion of the ram.
Next, when the die assembly is lowered, first the tip of the cylinder abuts against the slide, but since the switching member is retracted, the piston is moved to the lower end side within the cylinder. At this time, the upper material, the pattern mount, and the cover film are also moved downward. At this time, the tip sides of the outer edges of the upper material, the pattern mount, and the cover film that have been folded downward abut against the tapered surface of the slide and are folded inward. When the die assembly is further lowered, the outer edges of the upper material, the pattern mount, and the cover film abut against the edges of the lower material and are rolled in and crimped, so that the upper material, the pattern mount, the cover film, and the lower material are integrated, and the can badge is completed.

As shown in Figures 5 to 8, the indexing mechanism 41 has a cam 43 fixed to the table rotation shaft 33 and arranged between the rotating table 35 and the top plate 30 of the base 13. The outer peripheral surface of the cam 43 has recesses 45 formed in a number corresponding to the number of steps required for the rotating table 35 to rotate once. In the case of this embodiment, the rotation angle of one step of the rotating table 35 is 45°, and eight recesses 45 are formed. The indexing mechanism 41 also has an indexing arm 47 installed on the top plate 30 of the base 13 so as to be rotatable about an axis 46, and a cam follower 49 engaged with the recess 45 of the cam 43 is attached to one end of the indexing arm 47. The other end of the indexing arm 47 is connected to an air cylinder 51 that biases the indexing arm 47 toward the cam 43 by the cam follower 49. This air cylinder 51 is connected to an air supply/exhaust pipe (not shown).

Further, the lower mold rotating section 15 has a rotary table driving section 53. A motor 55 is installed in the rotary table driving section 53, and a motor-side timing pulley 59 is fixed to an output shaft 57 of the motor 55. A table rotation shaft-side timing pulley 61 is fixed to the lower end side of the table rotation shaft 33, and a timing belt 63 is wound around the motor-side timing pulley 59 and the table rotation shaft-side timing pulley 61.
When the output shaft 57 of the motor 55 is rotated, the rotation of the output shaft 57 is transmitted to the table rotation shaft 33 by the timing belt 63, thereby rotating the rotary table 35. The motor 55 is controlled to intermittently rotate the rotary table 35 by one step (45°) at a time, and each time, the cam 43 of the indexing mechanism 41 is engaged with the cam follower 49, and the rotary table 35 is accurately positioned.

As shown in FIG. 7, the lower mold rotating section 15 has eight lower mold units 71. The lower mold units 71 are installed at equal intervals in the circumferential direction on the outer periphery of the rotating table 35.

In addition, an end member support shaft 117 is provided at the center of the lower mold movable plate 77 so as to protrude downward. A through hole 119 is formed in the lower mold base plate 73, and a through hole 121 is also formed in the rotating table 35, and the end member support shaft 117 passes through the through hole 119 and the through hole 121 and protrudes below the rotating table 35. In addition, an end member 125 is fixed to the lower end side of the end member support shaft 117.

Also, as shown in FIG. 7, eight through holes 127 are formed in the rotating table cover 37, and the lower die unit 71 is installed through the through holes 127, so that the lower die 91 is exposed on the upper side of the rotating table cover 37.

As shown in FIG. 2, the front side of the base 13 is the badge body/shell loading section 17. The eight lower dies 91 are arranged in a row, two at a time, in the badge body/shell loading section 17. The worker loads the shell 5 into the lower die 91R located on the right side of the front side of the base 13, and loads the badge body 3 into the lower die 91L located on the left side of the front side of the base 13. In addition, a feed switch 133 is installed on the right side of the badge body/shell loading section 17, and the worker operates the operating lever 133a of the feed switch 133 to rotate the rotating table 35 counterclockwise (in the direction of the arrow a in FIG. 2) in two intermittent steps of 45° each, for a total of 90°.

As shown in FIG. 2, the design sheet carrying means 19 is installed on the outer periphery of the lower mold rotating section 15 on the base 13, in front of the badge body/shell carrying section 17 in the counterclockwise direction. As shown in FIG. 11, the design sheet carrying means 19 is composed of a design sheet holding section 141 and a design sheet carrying device 143. In addition, a design sheet imaging means 146 is installed near the design sheet carrying means 19.

As shown in Figures 11 and 12, the design sheet holding section 141 is provided with a rotating table support section 144 fixed to the base 13, and a rotating table 145 is rotatably mounted on the rotating table support section 144. The rotating table 145 is composed of an upper, approximately disk-shaped holding section main body installation section 147 and a shaft section 149 formed protruding below the holding section main body installation section 147. The lower end side of the shaft section 149 penetrates the rotating table support section 144 and the top plate 30 of the base 13 and protrudes below the top plate 30.

A recess 151 is formed in the holder body installation section 147 of the rotating table 145, and a holder body installation plate 153 is engaged and fixed in this recess 151. A holder body 155 is installed on the holder body installation plate 153. The holder body 155 is a hollow cylinder with an open upper side. The holder body 155 is split vertically in two and is composed of a pair of holder body elements 157 and 159. A magnet (not shown) is embedded flush on the holder body element 157 side, while a magnetic material (not shown) is embedded flush on the holder body element 259 side. The pair of holder body elements 157 and 159 are attracted and fixed via the magnet and magnetic material.

An engagement protrusion (not shown) is formed on the bottom surface 161 of the holding unit main body element 157, and an engagement recess 163 is formed on the holding unit main body installation plate 153. The holding unit main body element 157 is fixed by a bolt (not shown) with the engagement protrusion (not shown) engaged with the engagement recess 163 of the holding unit main body installation plate 153. An engagement protrusion 167 is also formed on the bottom surface 165 of the holding unit main body element 159, and the holding unit main body element 159 is combined with the holding unit main body element 157 by engaging the engagement protrusion 167 with the engagement recess 163 of the holding unit main body installation plate 153, thereby forming the holding unit main body 155.

A spacer 169 is installed on the bottom side of the holding body 155, and a lift 171 is installed on the upper side of the spacer 169. A plurality of design sheets 7 are stacked on the lift 171 inside the holding body 155. A shaft 175 is installed on the lower side of the lift 171. This shaft 175 is connected to the spacer 169. An actuator 177 is installed on the lower side of the top plate 30 of the base 13, and when the tip of the rod 179 of the actuator 177 rises and penetrates the bottom of the holding body 155 and abuts against the spacer 169, the lift 171 integrated with the spacer 169 and the design sheet 7 are raised upward ( _Z1 axis direction) in the holding body 155. If the rod 179 is moved downward, the lift 171 integrated with the spacer 169 and the design sheet 7 are lowered in the holding body 155.

In addition, a peeling member 181 is installed on the upper end surface of the holding unit main body element 157, and a peeling member 183 is also installed on the upper end surface of the holding unit main body element 159. By combining the holding unit main body elements 157 and 159, the peeling members 181 and 183 form a design sheet passing portion 185. The peeling member 181 is fixed by screwing a bolt 188 into the holding unit main body element 157 through a through hole 181a of the peeling member 181. In addition, the peeling member 183 is fixed by screwing a bolt 189 into the holding unit main body element 159 through a through hole 183a of the peeling member 183.

The inner diameter of the holding section main body 155 is set to be slightly larger than the outer diameter of the design sheet 7. In contrast, the inner diameter of the design sheet passing section 185 is set to be slightly smaller than the outer diameter of the design sheet 7. The design sheet is removed from the holding section main body 155 by being vacuum-adsorbed by the design sheet carrying device 143, but at that time, the second or subsequent design sheets 7 may be attached under the top design sheet 7 due to static electricity or the like. In this case, the second or subsequent design sheets 7 are peeled off and dropped by the design sheet passing section 185. The top design sheet 7 has a larger diameter than the design sheet passing section 185, but is removed as is due to the superior vacuum adsorption force.

A motor 191 is installed below the top plate 30 of the base 13, and a pulley 193 is fixed to the output shaft of the motor 191. A pulley 195 is also fixed to the lower end of the shaft portion 149 of the rotating table 145, and a timing belt 197 is wound around the pulley 193 and the pulley 195. This causes the holding unit main body 155, and thus the design sheet 7, to be rotated by the motor 191.

As shown in FIG. 11, the design sheet delivery device 143 is composed of an actuator 203 supported by pillars 201, 201 erected on the base 13, an air cylinder 207 installed on a slider 205 of the actuator 203, and a suction head 213 installed via a bracket 211 on the tip side of the piston 209 of the air cylinder 207. The suction head 213 is composed of a lifting cylinder 215 and a suction pad 217. An air supply/discharge pipe (not shown) is connected to the air cylinder 207, and an air suction tube (not shown) is connected to the lifting head 215.

The suction head 213 is moved in the horizontal _X2 direction between the lower die 91 and the design sheet holding part 141 by the slider 205 of the actuator 203. The actuator 203 is, for example, a ball screw shaft/ball nut type, and the ball screw shaft is rotated by a drive motor to move the ball nut in the _X2 direction, and the slider 205 fixed to the ball nut also moves in the _X2 direction. The suction head 213 is raised and lowered in the vertical _Z2 direction by the air cylinder 207. As a result, the design sheet 7 held by the design sheet holding part 141 is sucked by the suction pad 217 and moved to the lower die 91, and the design sheet 7 is carried onto the shell 5 placed in the lower die 91 in the can badge main body/shell carrying part 17.
The design sheet 7 is raised to a height at which it can be sucked by the suction pad 217 by raising the lift 171 with the actuator 177 .

11, on the outer periphery of the holding body 155, support columns 221 and 223 are erected on the top plate 30 of the base 13, a laser sensor 225 is installed on the support column 221, and a reflector 227 is installed on the support column 223. The holding body 155 is formed with laser passage recesses 229 and 231, and by rotating the holding body 155, the laser passage recesses 229 and 231 are arranged in a straight line between the laser sensor 225 and the reflector 227. A laser is irradiated from a light emitting portion (not shown) of the laser sensor 225 to the reflector 227, and depending on whether the laser reflected by the reflector 227 is detected by a light receiving portion (not shown) of the laser sensor 225, it is determined whether the design sheet 7 in the holding body 155 is at a height position where it can be adsorbed by the suction pad 217 and whether the design sheet 7 is present in the holding body 155.
The detection by the laser sensor 225 is performed over a certain width, for example, a width that can cover about 10 to 20 design sheets 7. Therefore, when about 10 to 20 design sheets 7 are taken out, the height position of the top design sheet 7 falls below a predetermined height position, which is detected by the laser sensor 225, and the lift 171 is raised.

In addition, a de-electrifying air nozzle 235 is installed on the support 221, and an air tube (not shown) is connected to this de-electrifying air nozzle 235. The de-electrifying air nozzle 235 is bellows-shaped and is deformed so that its nozzle is at a specified height and orientation. The specified height and orientation are the height and orientation of the design sheet 7 adsorbed to the suction pad 217, and by spraying air there, the second and subsequent design sheets 7 that are adsorbed by static electricity below the topmost design sheet 7 are peeled off and dropped from the topmost design sheet 7.

11, the design sheet imaging means 146 is composed of a support 241 installed on the base 13, a support arm 243 arranged from the upper end of the support 241 across the design sheet carry-in device 143, an XY table 245 installed on the tip of the support arm 243, a hanging arm 247 installed so as to be movable in the _X3 and _Y3 directions by the XY table 245, and a CCD camera 249 as an imaging means installed on the tip of the hanging arm 247. The horizontal position of the CCD camera 249 is manually adjusted by the XY table 245.

The CCD camera 249 captures an image of the top design sheet 7 held in the design sheet holding unit 141, and compares it with reference image data that has been captured and stored in advance to calculate the circumferential positional deviation. Based on the calculated circumferential positional deviation, the holding unit body 155 of the design sheet holding unit 141 is rotated to eliminate the circumferential positional deviation.

The above-mentioned reference image data is as shown in FIG. 13(a) and is obtained in the following procedure. There is a monitor 250 that displays an image taken by a CCD camera 249, and a reference line ML is displayed at the apex of this monitor 250. Meanwhile, a reference line ml is also displayed at the apex on the outer periphery of the design sheet 7. For example, suppose that the top design sheet 7 is photographed by the CCD camera 249 and the image is as shown in FIG. 13(b). In this case, the reference line ml of the design sheet 7 is shifted in the circumferential direction with respect to the reference line ML of the monitor 250. Therefore, the holding part main body 155 of the design sheet holding part 141 is manually rotated to bring the reference line ml of the design sheet 7 closer to the reference line ML of the monitor 250 as shown in FIG. 13(c), and the state shown in FIG. 13(a) is obtained. The image data at that time is stored as the reference image data.

As shown in FIG. 2, the protective film delivery means 21 is installed on the outer periphery of the lower mold rotation section 15 on the base 13 and in front of the design sheet delivery means 19 in the counterclockwise direction. As shown in FIG. 14, the protective film delivery means 21 is composed of a protective film holding section 261 and a protective film delivery device 263.

The protective film holding portion 261 has the same configuration as the design sheet holding portion 141, except that there is no mechanism for rotating the holding portion main body 155, and the holding portion main body 155 is fixed in a state in which the laser passing recesses 229, 231 are arranged in a straight line between the laser sensor 225 and the reflector 227.The same parts are shown with the same symbols in the figure and their explanations are omitted.
The protective film input device 263 has substantially the same configuration as the design sheet input device 143, and the same parts in the figure are denoted by the same reference numerals and their explanation will be omitted.
The protective film feeding means 21 feeds the topmost protective film 9 among the protective films 9 held by the protective film holding portion 261 into the lower mold 91 onto the design sheet 7 placed on the shell 5.

Also, as shown in FIG. 14, a de-electrifying air nozzle 265 is provided. An air tube (not shown) is connected to this de-electrifying air nozzle 265. This de-electrifying air nozzle 265 is fixed to the upper side of the holding part body 155 of the protective film holding part 261 so as to blow de-electrified air, and when a second or subsequent protective film 9 is attached to the protective film 9 to be removed by the suction nozzle 213 due to static electricity, the air is blown onto the protective film 9, causing it to peel off and fall.

As shown in FIG. 2, the press means 23 is installed on the outer periphery of the lower die rotating part 15 on the base 13 and in front of the protective film carrying means 21 in the counterclockwise direction. As shown in FIG. 15, a support table 271 is installed on the press means 23, and a servo press machine 273 is installed on the support table 271. The servo press machine 273 is composed of a drive motor (not shown), a ball screw (not shown) that rotates via a rotation transmission means by the rotation of the drive motor, and a ram 276 that is screwed into the ball screw and moves up and down. In addition, an upper die 281 is attached to the ram 276. The upper die 281 is composed of an inner upper die 283 installed at the tip of the ram 276 and an outer upper die 285 installed on the outer periphery of the inner upper die 283 so as to be able to move up and down. A stopper 287 that moves up and down together with the inner upper die 283 is fixed to the base end side of the inner upper die 283.

The press means 23 also has a die switching mechanism 291. The die switching mechanism 291 is composed of an air cylinder 293 that is connected to the stopper 287 via a bracket 288 and moves up and down together with the stopper 287 and the inner upper die 283, and a fork 295 that is moved horizontally toward the inner upper die 283 by the air cylinder 293. The bracket 288 moves up and down along guide members 290, 290.

The operation of the upper die 281 and the lower die 91 is switched between a state in which the fork 295 is advanced and inserted between the outer upper die 285 and the stopper 287, and a state in which the fork 295 is retreated and removed from between the outer upper die 285 and the stopper 287.

16, a space 301 is formed inside the outer upper die 285, in which the inner upper die 283 can move up and down relatively. Also, a recess 303 is formed on the lower side of the inner upper die 283. A space 311 is formed inside the outer lower die 95, in which the outer lower die 93 can move relatively. Also, the upper end side of the space 311 is expanded in diameter, and a step 313 is formed.
As mentioned above, in the lower mold 91 into which the can badge body 3 is carried, a tapered portion 315 is formed on the inner edge of the step portion 313 of the outer lower mold 95, as shown in Figures 18, 19 and 20, and a circular recess 312 is formed on the upper end surface of the inner lower mold 93 in which the safety pin 4 of the can badge body 3 is accommodated.

First, as shown in Fig. 16, the fork 295 is advanced and inserted between the outer upper die 285 and the stopper 287, so that the relative movement between the inner upper die 283 and the outer upper die 285 is restricted. In this state, as shown in Fig. 17, when the upper die 281 is lowered by the servo press machine 273, the outer lower die 95 is largely urged downward by the outer upper die 285, and the inner lower die 93 is protruded above the step 313 in the outer lower die 95. As a result, the design sheet 7 and the protective film 9 are deformed along the shape of the shell 5 in the lower die 91, and the outer peripheral edges of the design sheet 7 and the protective film 9 are folded downward in Fig. 17.
Thereafter, as shown in FIG. 18, when the upper die 281 is raised, the shell 5, the design sheet 7 and the protective film 9 are held in a laminated state inside the outer upper die 285.

Thereafter, when the turntable 35 is rotated 45° and the lower die 91 with the can badge main body 3 carried therein is positioned below the upper die 281, the fork 295 is retreated and removed from between the outer upper die 285 and the stopper 287, as shown in Fig. 18. This allows relative movement between the inner upper die 283 and the outer upper die 285.
As shown in Figure 19, when the upper die 281 is again lowered to the lower die 91 by the servo press 273, the tip of the outer upper die 285 abuts against the step portion 313 of the outer lower die 95, and is moved upward relative to the inner outer die 283 to a position where it abuts against the stopper 287.

Also, as shown in Figure 19, when the upper mold 281 is lowered, the inner upper mold 283 is pushed downward in Figure 19 from the outer upper mold 285, and the outer peripheral edges of the shell 5, the design sheet 7, and the protective film 9 are folded inward by the tapered surface 315 of the outer lower mold 95, and the tip sides (lower side in Figure 19) of the design sheet 7 and the protective film 9 ride up on the outer peripheral edges of the can badge body 3 placed on the inner lower mold 93.
Thereafter, as the upper die 281 is further lowered, the inner lower die 93 rises relative to the outer lower die 95, and as shown in Fig. 20, the can badge main body 3 enters inside the folded outer peripheral edges of the design sheet 7 and the protective film 9, and the outer peripheral edges of the design sheet 7 and the protective film 9 wrap around to encase the lower end side of the shell 5. Then, the outer edges of the shell 5, the design sheet 7 and the protective film 9 are crimped to the outer peripheral side of the outer edge of the can badge main body 3, and are integrated with the can badge main body 3, forming the can badge 1 as a finished product.
In Figure 20, the diameter of the can badge body 3 is depicted as smaller than in Figures 18 and 19, making it easier to see how the outer edges of the design sheet 7 and the protective film 9 wrap around and encase the lower end of the shell 5.

As shown in FIG. 2, the product discharge means 25 is installed on the outer periphery of the lower mold rotating part 15 on the base 13 and in front of the press means 23 in the counterclockwise direction. As shown in FIG. 21, the product discharge means 25 is composed of a product discharge device 401 installed on the base 13 and a product discharge conveyor 403 installed on the left side of the base 13. The product discharge device 401 is composed of an actuator 413 supported by a support 311 erected on the base 13, an air cylinder 417 installed on a slider 415 of the actuator 413, and a suction head 423 installed via a bracket 421 on the tip side of the piston 419 of the air cylinder 417. An air supply/discharge pipe (not shown) is connected to the air cylinder 417, and an air tube (not shown) is connected to the suction head 423.

The suction head 423 is moved in the X4 _- axis direction between the lower die 91 and the product discharge conveyor 403 by the slider 415 of the actuator 413. The actuator 413 is, for example, of a ball screw shaft/ball nut type, and the ball screw shaft is rotated by a drive motor to move the ball nut in the _X4 direction, and the slider 415 fixed to the ball nut also moves in the _X4 direction. The suction head 423 is raised and lowered in the Z4 _- axis direction by the air cylinder 417. As a result, the can badges 1 held by the lower die 91 are sucked by the suction head 423 and discharged to the product discharge conveyor 403. The can badges 1 placed on the product discharge conveyor 403 are moved to the front side of the base 13 and dropped and stored in a product storage box not shown.

Next, the operation of the first embodiment will be described.
First, the design sheet 7 is set in the design sheet holding portion 141 and the protective film 9 is set in the protective film holding portion 261 .
The holding section main body element 159 of the holding section main body 155 of the design sheet holding section 141 is removed. Next, the stacked design sheets 7 are set on the lift 171 with the surface on which the design is displayed facing upward. Next, the holding section main body element 159 is installed. This completes the setting of the design sheets 7 on the design sheet holding section 141.

The protective film 9 is also set on the protective film holding portion 261 in the same manner as the design sheet 7 is set on the design sheet holding portion 141.

Next, the reference image data shown in Fig. 13A is obtained. The procedure for obtaining the reference image data is as described above.
This completes the preparation work for starting up the can badge production apparatus 11.

Next, the can badge manufacturing operation is started by the can badge manufacturing apparatus 11 .
First, in the badge body/shell loading section 17, an operator loads the shell 5 into the lower die 91R located on the right side, and loads the badge body 3 into the lower die 91L located on the left side. When placing the badge body 3 in the lower die 91, the direction of the mark L displayed on the upper end surface of the outer lower die 95 is aligned with the direction of the safety pin 4 of the badge body 3.
Next, the operator operates the operating lever 133a of the feed switch 133. As a result, the rotary table 35 rotates intermittently in two steps of 45° each in the counterclockwise direction in FIG.
When the rotating table 35 is rotated intermittently in two steps of 45° each, for a total of 90°, the next two empty lower dies 91, 91 are positioned at the position of the can badge body/shell carrying-in section 17.
The worker carries a new shell 5 and a badge body 3 into the two lower dies 91 , 91 , respectively, and operates the operating lever 133 a of the feed switch 133 .
Thereafter, the same operations are repeated.

The lower mold 91 into which the shell 5 has been carried by the first 90° rotation of the rotary table 35 is positioned at the design sheet carrying position by the design sheet carrying means 19. In this state, the uppermost design sheet 7 of the design sheet holding section 141 is imaged by the design sheet imaging means 146 to obtain actual image data.
Next, the actual image data is compared with the previously acquired reference image data to calculate the circumferential positional deviation of the uppermost design sheet 7. Based on the calculated circumferential positional deviation, the holding part main body 155 of the design sheet holding part 141 is rotated by a predetermined angle. This eliminates the circumferential positional deviation of the uppermost design sheet 7.

Next, the design sheet carrying means 19 carries the top design sheet 7 of the design sheet holding unit 141 onto the shell 19 in the lower mold 91. At this time, air is ejected from the charge-removing air nozzle 235 to peel off and drop the second and subsequent design sheets 7 that are electrostatically attracted to the top design sheet 7 from the top design sheet 7. Thereafter, the holding unit body 155 of the design sheet holding unit 141 is rotated so that the laser passage recesses 229, 231 of the holding unit body 155 are aligned in a straight line between the laser sensor 225 and the reflector 227 of the design sheet holding unit 141, and the height of the design sheets 7 stacked in the holding unit body 155 is confirmed by the laser sensor 225. If the height of the design sheets 7 stacked in the holding unit body 155 is lower than the height that can be attracted by the suction pad 217, the lift 171 in the holding unit body 155 is raised. If there is only a small amount of design sheet 7 remaining in the holding body 155, refill the holding body 155 with design sheet 7 as necessary.

The lower die 91 on which the shell 5 and design sheet 7 are placed is positioned at a protective film introduction position by the protective film introduction means 21 by the protective film introduction means 21. The uppermost protective film 9 of the protective film holding portion 261 is introduced onto the design sheet 7 in the lower die 91 by the protective film introduction means 21. At this time, air is blown from the static electricity removing air nozzle 265 to peel off and drop the protective film 9 that is attached by static electricity to the protective film 9 to be removed by the suction nozzle 213.
Thereafter, the laser sensor 225 of the protective film holding portion 261 checks the height of the protective film 9 stacked in the holding portion body 155 of the protective film holding portion 261. If the height of the protective film 9 stacked in the holding portion body 155 is lower than the height at which the suction pad 217 can suck it, the lift 171 in the holding portion body 155 is raised. If the remaining amount of the protective film 9 in the holding portion body 155 is low, the protective film 9 is replenished in the holding portion body 155 as necessary.

Next, the lower mold 91 containing the shell 5, the design sheet 7 and the protective film 9 is moved to the pressing position by the pressing means 23 by the latter 45° rotation of the next 90° rotation of the rotary table 35. In this state, the fork 295 is advanced as shown in FIG.
Next, as shown in FIG. 17, the upper die 281 is lowered, and the design sheet 7 and the protective film 9 are deformed along the outer diameter of the shell 5 to be integrated.
18, the upper die 281 is raised. Inside the outer upper die 285 of the upper die 281, the integrated shell 5, design sheet 7 and protective film 9 are held.

Next, by rotating the turntable 35 by the first 45° of the next 90°, the lower die 91 into which the can badge body 3 has been carried is positioned at the pressing position by the pressing means 23. In this state, the fork 295 is moved backward as shown in FIG.
Next, the upper mold 281 is lowered, and as shown in Figures 19 and 20, the shell 5, design sheet 7 and protective film 9 are crimped onto the can badge body 3 to be integrated, forming the can badge 1 as a finished product.
Next, when the upper die 281 is raised, the can badge 1 is left in the lower die 91 .

Next, the turntable 35 rotates by the latter 45° of the next 90° rotation, so that the lower die 91 on which the can badge 1 is placed is positioned at the discharge position by the product discharge means 25. The can badge 1 is removed from the lower die 91 by the product removal device 301 and discharged onto the product discharge conveyor 403.
The can badges 1 placed on the product discharge conveyor 403 are discharged to the front side of the base 13 .
Thereafter, the same operation is repeated.

Next, the effects of the first embodiment will be described.
First, the can badges 1 can be easily manufactured. This is because the can badges 1 are manufactured by the can badge manufacturing apparatus 11 according to the present embodiment, and all other operations are automated except for manual operations by workers in the can badge main body/shell carrying-in section 17.

In addition, in the can badge manufacturing apparatus 1 of this embodiment, the can badge main body/shell loading section 17, the design sheet loading means 19, the protective film loading means 21, the press means 23, and the product unloading means 25 are arranged in sequence on the outer periphery of the rotating table 35, so that the configuration is simplified and compact.
Further, the can badge body/shell carrying-in section 17 is provided with a feed switch 133 for rotating the turntable 35 at a prescribed angle to progress the manufacturing process, so that the worker need only operate the operating lever 133a of the feed switch 133 in accordance with his/her own working speed, and the can badges 1 can be manufactured at the worker's own pace.

In addition, it is possible to easily manufacture a can badge 1 in which the orientation of the safety pin 4 and the orientation of the design sheet 7 match. This is because a mark L indicating the orientation of the safety pin 4 of the can badge main body 3 placed on the inner lower mold 93 is displayed on the upper end surface of the outer lower mold 95, so that when the can badge main body 3 is set in the outer lower mold 95, the safety pin 4 can be set in an accurate position by aligning it with the mark L, and the image of the top design sheet 7 of the design sheet holding section 141 obtained by the design sheet imaging means 146 is compared with a reference image captured in advance to detect the circumferential deviation, and the design sheet 7 is rotated to eliminate the deviation.

In addition, the holding section main body 155 of the design sheet feed means 19, which holds the design sheet 7 in a stacked manner, and the holding section main body 155 of the protective film feed means 21, which holds the protective film 9 in a stacked manner, have a vertically split structure of holding section main body elements 157, 159, making them easy to disassemble and assemble, and also easy to maintain.
In particular, during assembly, the holding portion main body elements 157 and 159 are attracted to each other via a magnet and a magnetic material, so that the assembled state can be firmly maintained. Conversely, by pulling out the holding portion main body element 159 with an appropriate force, the attracted and fixed state of the holding portion main body elements 157 and 159 can be released.

In addition, the holding portion main body 155 of the design sheet holding portion 141 is provided with a design sheet passing portion 185 for separating the design sheets 7 one by one, thereby effectively restricting the removal of the second and subsequent design sheets 7.
Even if the second or subsequent design sheets 7 are removed while adhering to the uppermost design sheet 7, they can be peeled off and dropped by blowing air from the charge eliminating air nozzle 235.
The same is true for the protective film 9. Since the holding part main body 155 of the protective film holding part 261 is provided with the protective film passing part 185 for separating the protective films 9 one by one, it is possible to effectively restrict the removal of the second and subsequent protective films 9.
Even if the second or subsequent protective film 9 adheres to the uppermost protective film 7 and is to be removed, it can be peeled off and dropped by blowing air from the charge eliminating air nozzle 265 .
In addition, a laser sensor 225 detects whether the topmost design sheet 7 is at a specified height and adjusts the level, so that the design sheet 7 can be reliably removed and carried in, and when a design sheet 7 runs out, it can be detected to prompt the user to replenish it.
The same is true for the protective film 9, and a laser sensor 225 is used to detect whether the top protective film 9 is at a specified height and adjust the level accordingly, so that the protective film 7 can be reliably removed and carried in, and also it is possible to detect when a protective film 9 has run out and prompt the user to replenish it.
Furthermore, the replenishing of the design sheets 7 can be performed simply by removing only the holder body element 159. This is the same when replenishing the protective films 7.
In addition, by inserting a fork 295 between the outer upper die 285 and the stopper 287 into the press means 23, the vertical position of the outer upper die 285 relative to the inner upper die 283 can be appropriately changed, so that a single press means 23 can be used to both mold the shell 5, design sheet 7 and protective film 9, and to crimp the shell 5, design sheet 7 and protective film 9 to the can badge body 3.

Next, a second embodiment of the present invention will be described.
In this second embodiment, the holding body 155 is also split vertically into two and is composed of a pair of holding body elements 157 and 159. A plurality of engaging protrusions 501 (two on each side, a total of four in this embodiment) are formed on a split surface 161 of the holding body element 157. Four engaging recesses 503 corresponding to the engaging protrusions 501 are formed on a split surface 165 of the holding body element 159. The holding body elements 157 and 159 are combined to engage the engaging protrusions 501 and the engaging recesses 503, thereby forming the holding body 155. The engaging protrusions 501 are made of a ferromagnetic material, and a magnet (not shown) is installed at the bottom of the engaging recesses 503, and when the engaging protrusions 501 and the engaging recesses 503 are engaged, they are attracted to each other and fixed.

When installing the holding portion main body 155, a spacer 169 and a lift 171 are inserted into one of the holding portion main body elements 157, 159, and the holding portion main body elements 157, 159 are combined in advance to assemble the holding portion main body 155, and then the engaging protrusion 501 is engaged with the engaging recess 503 of the holding portion main body installation plate 153.
The other configurations are the same as those of the first embodiment, and the same parts in the drawings are given the same reference numerals and their explanations are omitted.

In the case of this second embodiment, the holding unit main body elements 157, 159 can be combined and easily assembled in a positioned state by engaging the engaging protrusions 501 and the engaging recesses 503, and at least the engaging protrusions 501 of the holding unit main body element 157 are made of a magnetic material and a magnet is installed in the engaging recesses 503, so that the holding unit main body elements 157, 159 can be easily assembled while preventing inadvertent disassembly.

It should be noted that the present invention is not limited to the first and second embodiments.
First, in the first and second embodiments, the shells and badge bodies are manually carried in by workers, but it is also possible to configure it so that they are carried in automatically in the same way as design sheets, etc. A specific configuration for this would be to configure it with a holder and a carry-in device, similar to the design sheet carry-in means.
Next, in the first and second embodiments, a circular recess for accommodating a safety pin is provided in the inner lower mold of the lower mold into which the badge body is carried, but it is also possible to make the shape of this recess elongated to match the shape of the safety pin. In this case, the orientation of the safety pin and therefore the badge body will necessarily be regulated, making the mark provided on the outer lower mold unnecessary.
The single-axis actuators used in various places have been explained using the ball screw shaft/ball nut type as an example, but there are also various other configurations that can be considered, such as the pulley and belt type, the rack and pinion type, and the linear guide type.
Also, various driving methods are envisaged.
Additionally, the configurations shown in the drawings are merely examples.

The present invention relates to a parts loading device for a badge manufacturing device, and in particular to a device that is designed to facilitate assembly and disassembly, and is suitable, for example, for space-saving automatic or semi-automatic badge manufacturing devices.
