Shouted and contained. The plate storage container 19 is continuously loaded on the carry-out belt conveyor 20 and continuously stores one car body worth (one set) of various plates 5, and is a cassette that is removable from the carry-out belt conveyor 20. It is a type container. By removing this plate storage container 19 from the belt conveyor 20 and using it, marking of the plate is completed. In addition, in the above-mentioned description, the example of use was described in which the first marking system and the second marking system were operated simultaneously. According to this method of use, the finishing time for one set of plates can be shortened. However, if there is time, for example, only the first marking system can be operated and the second marking system can be stopped. Next, details of each of the above components will be explained. Plate supply devices 100 and 200 Plate supply devices 100 and 200 are basically configured in the same way. Therefore, in the following description, only the plate feeding device 100 will be described. FIG. 4 shows a schematic configuration diagram of an embodiment of the plate feeding device 100, in which A is a front view thereof, B is a side view thereof, and C is a perspective view of a pusher. In the figure, hoppers 11A, 11B, 11 of the hopper part 11
Various plates 5 are inserted from the respective upper openings of C.
are classified and accommodated. In this embodiment, for example, a wide long plate is housed in the hopper 11A, a wide short plate is housed in the hopper portion 11B, and a narrow plate is housed in the hopper 11C. The plate supply device 100 is
This hopper part 11 (hoppers 11A, 11B, 11
C), and is comprised of a pusher drive mechanism 123 and a plate delivery mechanism 124 disposed on the bottom side of the hopper section 11. Pusher mechanism 12
3 is a pusher 125, a pusher mounting frame 126,
Rack 1 fixed to this pusher mounting frame 126
27, a pin-on 128 that meshes with this rack and transmits the driving force of the drive motor 129 to the pusher 125
and photo sensors 130 and 131 for detecting the position of the pusher 125. Pushya 125
is the step A corresponding to the thickness of one plate 5
The plate 5 is placed on the lower surface 133 and an upper surface 132 and a lower surface 133. The pusher mounting frame 126 fixes the pusher 25 at the upper end, and has a drive motor 129 and a pin-on 12.
8 and rack 127, and is guided by a fixed frame 134 via a ball bearing 135 to reciprocate linearly. Furthermore, light shielding plates 136 and 137 are fixed to the pusher mounting frame 126. The light shielding plate 136 blocks light from the photo sensor 130 to detect the reverse position of the pusher 125, and the light shielding plate 137 blocks light from the photo sensor 131 to detect the starting position of the pusher 125. Next, the plate feeding mechanism 124 is provided near the maximum ejection position of the pusher 125 and includes a rubber roller 139 that is rotationally driven by a drive motor 138 and a presser roller 140 that is provided opposite the rubber roller 139. Spring 14
1 is fixed to the hopper frame 146 at one end, and the other end applies pressing force to the presser roller 140 against the rubber roller 139. The gate plate 142 is connected to the hopper frame 14
Provided on the inner surface of the protruding side of the plate 5 of 6,
There is a gap B between the pusher 125 and the lower surface 133, which is slightly larger than the thickness of one plate 5. Further, 143 is a push button switch provided on the hopper frame 146, and 144 and 145 are photo sensors for detecting the upper and lower earthquakes of the plate 5 provided on the hopper frame 146. The functions of the plate supply device configured as described above will be explained. When the pusher 125 moves in the direction of the arrow X due to linear motion driven by the drive motor 129 and transmitted via the pin-on 128 and the rack 129, the plate 5 placed on the lower surface 133 of the pusher 125 also moves in the same way. However, it is blocked by the gate plate 142. However, since there is a gap B between this gate plate 142 and the lower surface 133 of the pusher 125, which is slightly larger than the width of one plate 5, the lowest one of the plates 5 is connected to the gate plate 142. It passes under the body and is ejected along with the pusher 125. After the plate 5 is pushed out by the pusher 125, the stamp conveyor 1 of the plate conveying device 300 is moved by the rubber roller 139 and the presser roller 140.
Sent out on 3rd. When the pusher 125 starts, the step A between the upper surface 132 and the lower surface 133
is located behind the plate 5 and has a gap W. The existence of this gap W is desirable in order to lower the starting torque of the drive motor 129, and is usually about 1
It is set to about mm to 5 mm. Further, by configuring the drive motor 129 to stop naturally when pushing out the pusher 125 in the direction of the arrow X, there is less impact on the pusher drive mechanism 123, less electrical noise is generated, and the mechanism is simple. This has the advantage of becoming. However, due to natural stoppage, the pusher 125 may overrun. Therefore, the light shielding plate 130 of the photo sensor 130 that detects the reversed position of the pusher 125 is
is formed as long as the overrun. In order to confirm whether the pusher 125 is stopped at a position suitable for starting, the light shielding plate 137 operates the starting position sensor 131 when the pusher 125 is at the starting position. By confirming that both sensors 130 and 131 are operating at the same time,
The position of pusher 125 can be confirmed. Next, FIG. 5 shows an explanatory diagram of the pusher operation state, where A is a normal pusher state, B is a pusher state with a gap, C is a pusher failure state, and D is a gap removed state. In the figure, parts having the same functions as in FIG. 4 are given the same reference numerals. As shown in FIG. 5A, the plate 5 is not necessarily in the normal state in which it is pushed by the stepped portion A of the pusher 125 and projected with the gap W=0. As shown in FIG. 2B, the plate 5 may be carried by the contact friction between the plate 5 and the lower surface 133 and protrude with the gap W remaining. At this time, as the pusher 125 advances as shown in FIG.
42 and the lower surface 133 of the pusher 125,
It may become impossible to continue driving into the area.
To avoid this, the plate feeding mechanism 12
4, the rotation of the rubber roller 139 is stopped and it is made to function as a stopper to prevent the pusher 125 from advancing as shown in FIG.
After the value becomes zero, the drive motor 138 rotates the rubber roller 139 to send out the plate 5. At the same time, the photo sensor 130 detecting this position causes the drive motor 129 to rotate in the opposite direction, reversing the pusher 125 and returning it to the starting position. During this return, if the photo sensor 130 is shielded from light by the light shielding plate 136 and the photo sensor 131 is not shielded by the light shielding plate 137, the pusher 125 has not been returned to the starting position. to be reinstated. Plate conveying devices 300, 400 Plate conveying devices 300 and 400 are basically configured the same. Therefore, in the following description, only the plate conveying device 300 will be described. FIG. 6 shows a schematic configuration diagram of an embodiment of the plate conveying device 300, in which A is a front view thereof and B is a plan view thereof. In the plate conveying device 300, the plate 5 (wide plate 5A or narrow plate 5B) is selected and fed from the hopper section 11 of the plate feeding device 100. This plate conveying device 300 mainly includes a conveying belt 13, a fixed guide side plate 323, a stopper 324, a proximity switch 325, a plate length detection sensor 326, a plate width detection sensor 327, and a floating guide 32.
Consists of 8. In this embodiment, the conveyor belt 13 includes three rubber timing belts 329, a drive roller 330, a driven roller 331, presser rollers 332, 333, an intermediate roller 334, a drive motor 335, and the like. Fixed guide side plate 323
are provided sandwiching these three timing belts 329 and guide the wide plate 5A being conveyed. The stopper 324 is provided between the fixed guide side plates 323, projects from below on the surface of the timing belt 329, and moves the wide plate 5A to the marking position (third
The stopper rod 33 is stopped at the stamped fixed position S ₁ ) in the figure.
6. Solenoid 337 that lowers this stopper rod 336, stopper rod 336 and solenoid 337

and a solenoid 337. Further, the proximity switch 325 is
It is provided downward from above between the fixed guide side plates 323, and detects the tip of the wide plate 5A to stop the conveyor belt 13, and during this stop, the plate 5A
have them stamped. The plate length detection sensor 326 and the plate width detection sensor 327 are reflective photo sensors that detect the presence of the wide plate 5A from below. This is a sensor that detects the wide plate 5A. That is, this wide plate 5A includes a wide long plate 5AL and a wide short plate 5AS, and when the wide long plate 5AL is conveyed, the length detection sensor 32

turns on. Furthermore, the floating guide 328 is provided between the fixed guide side plates 323, sandwiching the timing belt 329 in the center in this embodiment.
This is a guide plate for the narrow plate 5B being carried out. When the narrow plate 5B is conveyed by the floating guide 328, both sensors 326 and 327 are turned off. Next, the plate conveying device 30 with the above-described configuration
The functions of 0 will be explained. Wide plate 5A protruded from hopper part 11 of plate supply device 100
is guided by the guide side plate 323 and carried in by the timing belt 329, and comes into contact with a stopper rod 336 protruding from the surface of the timing belt 329 and stops. At the same time, when the center of the tip of the wide plate 5A enters directly under the proximity switch 325,
The proximity switch 325 operates to stop the belt drive motor 335. Note that if this drive motor 335 suddenly stops, the timing belt 329
There is a possibility that the stop position of the wide plate 5A may change. For this purpose, the drive motor 3
35 will gradually come to a natural stop. Therefore, the stopper rod 336 is rotatably supported at the tip of the solenoid 337 by the pin 338. Spring 33
9 generates a vertical supporting force against the stopper rod 336. The plate length detection sensor 326 and the plate width detection sensor 327 detect two types of wide plates 5A having the same width and different length.
(that is, 5AL, 5AS) is detected as to which one has been completed. When the marking is completed and an unloading command is received, the drive motor 335 is driven again, and at the same time the solenoid 337 is activated to move the stopper bar 3.
36 is pulled down, and the wide plate 5A is carried out from the plate transport device 300. Next, FIG. 7 shows a schematic configuration diagram of the floating guide in FIG. 6, where A is a front view thereof, B is a state when the narrow plate is carried in, and C is a state when the narrow plate is carried out. In this figure, parts having the same functions as those in FIG. 6 are given the same reference numerals. The floating guide 328 has a concave cross-section, and guide portions 340 guide the narrow plate 5B on both sides.
and a narrow stopper portion 341 provided inside the guide portion 340. When carrying in the narrow plate 5B as shown in FIG. A or B, the floating guide 328 is
It floats up to the A state, and then descends to the 328B state when carrying out the narrow plate 5B as shown in FIG. Furthermore, when carrying in and out the wide plate 5A, the floating guide 328 descends from the surface of the timing belt 329 as shown in FIG. In this way, the lifting mechanism for lifting the floating guide 328 is the forward/reverse drive motor 34 in this embodiment.
2. It consists of a pulley 343 to which the rotation of the drive motor 342 is transmitted, a drive link 344 and a driven link 345 that rotate due to the rotation of the pulley 343. With the above-mentioned configuration, when loading and unloading the wide plate 5A, the levitation guide 328, which had been lowered from the surface of the timing belt 329, receives the command to load the narrow plate 5B and reaches the maximum height as shown in FIG. It will be in the 328A state of the floating position. The narrow plate 5B is guided by this floating guide 328 and carried in by the timing belt 329 in the center,
It comes into contact with the stopper part 341 and stops. On this occasion,
The tip of the narrow plate 5B enters directly under the proximity switch 325 shown in FIG.
is operated, the belt drive motor 335 is stopped, and the carrying-in operation of the timing belt 329 is stopped.
After the marking is completed, the floating guide 328B is in the state of being lowered to the intermediate position as shown in FIG. In this intermediate position, the narrow plate 5B
The stop by the stopper portion 341 at the time of carrying in is released, and the timing belt 329 starts carrying out the movement, and the narrow plate 5B is carried out. Note that the floating guide 328 is connected to the wide plate 5.
When A is carried in, it is further lowered from the floating guide 328B and the timing belt 329
The wide plate 5A is brought to a completely downward position from the surface thereof, and does not pose a hindrance to the loading and unloading of the wide plate 5A. Plate unloading device 500 FIG. 8 shows a plate unloading device 500 according to the present invention.
1 shows a schematic configuration diagram of an embodiment of the present invention. In the figure, parts having the same functions as in FIGS. 2 and 3 are given the same reference numerals. The plate delivery device 500 includes a shooter 18 that is tiltably provided at the bottom of a shooter frame 522, a cassette-type plate storage container 19, a delivery conveyor 20, a delivery guide plate 523, an extension lane 524, and an inclined lane 525. It consists of. Of these, 18
Above, the plate of the first stamping system is conveyed by the first stamping conveyor 13 from the back side of the paper surface to the front side (this direction corresponds to the direction of arrow _X1 in FIG. 2), and similarly from the front side of the paper surface The plates of the second stamping system are conveyed by the second stamping conveyor 14 toward the back side (this direction corresponds to the direction of arrow _X2 in FIG. will be put on hold. and,
When one vehicle body (one set) is collected, a one set completion signal is sent from the controller, and the shooter 18 is tilted by means not shown. This tilting of the shutter 18 causes the plate 5 to shoot (fall) onto the plate storage container 19.
I am made to do so. On the other hand, a large number of partition plates 526 are housed in the plate storage container 19, and when the plate storage container 19 is conveyed in the traveling direction _Y3 by the carry-out conveyor 20 and passes through the lower gate 527 of the shooter frame 522, the partition plates 526 are It is pushed down in the reverse direction _Y4 by the lower gate 527. Plate storage container 1
9 advances further and receives the plate 5 falling from the shooter 18 (S ₄ points shown in Figure 3)
When reaching this point, a frame feeding light shielding plate (not shown) provided on the bottom of the plate storage container 19 activates a photo sensor (also not shown) to stop the carry-out conveyor 20. At this time, the lower end of the most distal partition plate 526 comes into contact with the reversing guide 528 fixed to the conveyance guide plate 523. Due to this contact, the partition plate 526 is reversed in the advancing direction _Y3 , forming a V-shaped opening 529 between it and the next partition plate 526, and stands by in a state in which the plate 5 can be received. In this way, each time the shutter 18 is tilted, the plate storage container 19 advances one pitch at a time in the traveling direction Y3 based on the detection of the falling of the plate by means not shown, and the partition plate 526 moves forward in the direction of movement _Y3 . Each time, the plates 5 are reversed one by one in the traveling direction _Y3 to form a V-shaped opening 529 for receiving the falling plates, and one vehicle body worth (one set) of plates 5 is received each time. In this way, the plate storage container 19 is released from the carry-out conveyor 20 when the last partition plate 526 is reversed by the reversal guide 528. At this time, this plate storage container 19 is on the carry-out guide plate 523, and is pushed forward in the traveling direction _Y3 by the following plate storage container 19, and when it reaches the extension lane 524, it slides on the slope and is further carried out. Ru. Note that if this extension lane 524 is not used, the unloading guide plate 52
It is also possible to use a detection sensor 530 provided at the front end of the plate container 19 to notify that the plate container 19 has reached the tip of the carry-out guide 523. Furthermore, when there is no subsequent plate storage container 19 within the rear range N of the plate storage container 19 on the carry-out conveyor 20, a warning may be displayed to indicate that there is a shortage of containers. Note that the plate storage container 19 is connected to the carry-out conveyor 2.
However, if there is no subsequent plate storage container 19, a new plate storage container 19 is replenished, and this replenished plate storage container 19 is transferred to the previous plate storage container 19. The forward-fed plate storage container is kept on standby on the unloading guide plate 523 until it reaches the rear part. Therefore, in order to reduce the number of plate storage containers that are placed on standby on such an unloading guide plate 523, it is preferable that the conveying guide plate 523 is configured to be relatively short. In addition, slope lane 5
25 has its tip touching the rear end of the conveyor 20, and the plate 5 is placed on this inclined lane 525.
Empty plate storage containers 19 that have not yet been received are placed on the tower. Therefore, the empty plate storage container 19 is tilted in the direction of travel _Y3 of the slope lane 525.
It slides on the discharge conveyor 20. By the way, in this embodiment, about seven empty plate storage containers 19 can be loaded on the carry-out conveyor 20. One plate storage container 19 has approximately 20 partition plates 526 and can receive various plates for 20 vehicle bodies. Since the inclined lane 525 is far away from the worker located in front of the carry-out guide 523, it is difficult to replenish the empty plate storage container 19. For this purpose, the shooter frame 522 is provided with a switch 532 for raising and lowering the inclined lane.
By operating the lift switch 532, the inclined lane 525 is moved to a 5 inclined lane in the reverse direction _Y4 .
25' to facilitate replenishment of the empty plate storage container 19. Plate Storage Container Fig. 9 is a schematic configuration diagram of an embodiment of the plate storage container, and Fig. 10 is a schematic configuration diagram of a partition plate. 1
FIG. 1 shows an enlarged cross-sectional view taken along the line AA in FIG. 9. In FIGS. 9 to 11, the plate storage container 19
accommodates a large number of partition plates 526. This partition plate 526 is held between grooves 734A, 734A of support shafts 734, 734 that are opposed to each other at the lower part of the partition plate 526. In addition, tongue-like protrusion pieces 737, 73

will be carried out. Further, as described above, the carry-out guide 52 provided at the carry-out end of the carry-out conveyor 20
3, a reversing guide 528 is attached. When this plate storage container 19 is conveyed in the conveying direction _Y3 and the tongue-like protrusion piece 737 comes into contact with the reversing guide 528, the partition plate 526 is reversed from the reverse conveying direction _Y4 to the unloading direction _Y3 , and the 11th As shown in the figure, a V-shaped opening 529 is formed between the partition plate 526 and the other partition plate 526 before being reversed. By forming this opening 529, the plate 5 thrown out from the shooter 18 is easily accommodated between the partition plates 526. By the way, the width dimension D of the partition plate 526 is smaller than the width of the plate 5, so that the plate 5 can be easily taken out. [Effects of the Invention] As explained above, in the present invention, the plate delivery device is provided with a shutter which is disposed at the other end of the marking conveyor and is tiltable;
A plate storage container that accommodates a large number of partition plates and receives the plates with a V-shaped opening between the partition plates located below the plate that falls due to the tilting of the shooter; By being composed of an unloading conveyor for unloading,
Since plates of different shapes and sizes and descriptions are carried out one by one without changing the marking order, they are easily handled and work efficiency is improved. According to an embodiment of the present invention shown in FIGS. 2 and 3, two laser heads are arranged in parallel, and two hoppers housing various plates are moved in the front-rear direction. One end of two marking conveyors is connected to each of the hopper parts, and the desired plate selected by the movement of the hopper part is carried in, and the plate is engraved by the laser head. By connecting the unloading conveyor that carries out the collection and conveyance to the other end of the stamping conveyor that faces each other,
Parallel operation is possible, shortening the marking time, and independent operation is also possible, so the two sets of marking systems can back up each other and maintain their operating rate, and the stamped plate can be used for one vehicle (1 car body). Since the materials are collected in batches (sets) and transported out continuously, there are effects such as improved work efficiency.
