07 stops rising and descends. At the same time, the motor 129 rotates and the feed screw 12 is rotated via the pulleys 128, 130 and the timing belt 131.
6 rotates, and the movable frame 121 integrated with the guide bush 127 advances in the horizontal direction together with the vacuum box bodies 122a, 122b and the conduit 123 of each row, and the preprocessing device 124 is moved from above the mounting table device 101.
It reaches the top and stops there, releases the suction force by the blower 143, and picks up one sheet in each row on the pre-processing device 124 - the plated object 103a that has been conveyed.
At the same time, the movable frame 121 is moved back and returned to its original position, and the above operation is repeated again.

If the size of the plating object 103 to be supplied changes, the mounting table device 101 side uses a set screw 110.

7b; 328a and 328b are each provided with a "width adjustment means" so that the interval between the chucks 242 can be adjusted in accordance with the width size of the plated object 103 to be held. As the "width adjustment means" for this purpose, a pair of left and right holders 3 are used as shown in FIG.
27a, 327b; Thumb screws 342, 343 screwed into the upper parts of 328a, 328b are attached upwardly and pressed against the shaft 329a, thereby making the positions variable.

And a pair of front and rear, left and right holders 327a, 3
27b; A guide frame 347 is attached to the lower part of 328a, 328b. Although only the left side is shown in FIG. 14, this guide frame 347
are a pair on the left and right, and have latch-shaped introduction portions 348 on the left and right, and are arranged from the left to the right in FIG. Heto roller device 22
It is placed and moved along a pass line 240 on each belt 239 of 1.

Next, the operation of the chuck device 222 will be explained.

[Entry of the plating object 103] The plating object 103 remains parallel in the left and right direction until it reaches the eighth point.
It is first received into the roller device 221 from the left side in the figure. Referring to FIG. 11, each roller 226 is rotating via a motor 234 and a timing belt 235 as explained in the operation of the roller device 221, and the plated object 103 is placed on a pass line 240 on each belt 239. - It is transferred and guided to a predetermined position determined by the stopper 243, and the sensor 244 checks the presence of the plating object 103 and transmits a signal to the check device 222.

When the plating object 103 enters the roller device 222, the flap-like introduction portions 348 of the pair of left and right guide frames 347 attached to the lower portions of the holders 328a and 328b guide and restrict the entry state of the plating object 103. The pass line 240 is positioned so that the chuck 242 of the device 222 can securely pick up and hold the object 103 to be plated.
The plated material 103 is transferred above.

[Operation of the chuck device 222] Upon receiving a signal from the sensor 244, the "rotating means" first functions. The pressure cylinder 340 operates, the rod 338 moves, and the pinion 336 that engages with the rack 337 rotates, and accordingly, the pair of left and right shafts 330 move inwardly toward each other [10th
15], the claw 3 of the chuck 242
34 is the left and right sides 241, 332 of the plated object 103
Rotate diagonally from below and pick it up [first
8b], and then hold the plated object 103 in a horizontal state [FIG. 18a, which will be described later]. At this time,
The step portion 355 is on both left and right sides 24 of the plating object 103
1,332, so to speak, to make the holding state more reliable.

By such lifting and holding, the plated object 103 is instantly transferred from the roller device 221 to the chuck device 222.
It will be received by.

This kind of action is that of the first chuck device 323 on the inlet side of the plating device main body 220, while the second chuck device 324 on the outlet side uses a similar action to partially plate the plated object 322, which will be described later. The object to be plated is picked up and held by the chuck 321 (FIG. 19) of the second chuck device 324 from the "plating object placement section". and,
All plated objects 103 in parallel on both the input side and the output side,
322 is subjected to similar lifting and holding processing.

[Moving the frame 311] Next, the “moving device” functions to move the frame 311. That is, the rotation of the motor 320 is caused by the rotation of the belt 3.
19 to the ball screw 317, and the eighth
As shown in FIGS. 9 and 9, the guide 318 connected to the support frame 313 side is screwed into the ball screw 317, so that it is forced to move to the right in FIG. Since the support frame 313 and, by extension, the frame body 311 are connected to the guide 318, the support frame 313 and the frame body 311 are moved to the right in FIG. and move. This movement manifests itself as switching between the first and second chuck devices 323 and 324 on the inlet and outlet sides of the plating device main body 220. That is, the first chuck device 323 on the inlet side reaches above the "plated object placing section", and the second chuck device 324 on the outlet side reaches the right side in FIG. 8 [the imaginary line position in FIG. 7].

[Operation of the chuck device 222 again] The pair of left and right shafts 330 are rotated in the opposite direction to the previous one, and the chuck 242 is opened to release the lock of the plating object 103 held therein, and the "patch device 222" is opened. ” Allow the plated object 103 to fall under its own weight [first chuck device 323 on the entry side],
On the other hand, the plating material 322 onto the post-processing device 314
is taken out [second chuck device 324 on the outlet side]. That is, the plating objects 103 and 322 are supplied and discharged from and to the plating device main body 220 almost simultaneously.

[Returning movement of the frame 311] The "moving device" is operated again, and the frame 311 returns to the left in FIG.
The chuck device 323 waits for and receives a new plating object 103 that enters a predetermined position on the roller device 221, and performs the same function as described above. As soon as the plating process is completed, the same operation as above is performed in order to wait for and receive the plated object 322.

[Regarding Width Adjustment] In the above-described operation, a "width adjustment means" is used to make the chuck device 222 correspond to the plating objects 103 and 322 of different width sizes. That is, loosen the thumbscrews 342 and 343,
Left and right holders 327a, 327b; 328a,
328b is attached and the shafts 329a and 329b are used as guides to adjust the spacing, and furthermore, the spacing between the guide frames 347 forming the truss-shaped introduction portion 348 is simultaneously adjusted in accordance with the width of the plated objects 103 and 322. That will happen.

Plating device 400: Description will be made with reference to FIGS. 16 to 21.

This plating device 400 has a plating device main body 22

It is erected and supported by. Reference numeral 440 denotes a nozzle mounting section, which is arranged in each independent chamber 434 and is supplied with plating liquid from a plating liquid supply pipe (not shown) and is supplied to a plurality of nozzles 435 to equalize the internal pressure. rectifier plate 441
Equipped with. The unitized upper cover 425 and nozzle 435 are attached to the upper cover base 443 via screws 442 so as to be replaceable. Therefore, each unit can be replaced independently. The rest of the configuration of the plating device main body 220 is substantially the same as that of the conventional device, so a description thereof will be omitted.

The press device 422 is mainly composed of a gate-shaped base frame 444, a hanging vertical movement means 445, and a press block 446. The gate-shaped base frame 444 is in the width direction [direction of arrow B in FIG. 16]
It has a girder frame 447 and a pair of left and right leg frames 448 so as to have a gate shape. On the girder frame 447, a number of hanging vertical movement means 445 and press blocks 446 are arranged in the width direction according to the number of parallel plated objects 103. leg frame 4
48 is a main and sub roller 44 provided at the base.
9,450, the entire press device 422 can be freely moved in the inlet direction [the left side in FIGS. 7 and 8] and the outlet direction [the right side in FIGS. 7 and 8] of the plating device main body 220. Ru. In the illustrated example, the roller 44 is movable and retractable in the exit direction.
9,450 are engaged with rails 452 provided as a pair on the left and right sides on the exit side of the base 451. The main roller 449 supports the entire load of the press device 422, and the sub roller 450 prevents the main roller 449 from coming off the rail 452. Further, a "locking means" 420 is provided to fix the entire press device 422 in a predetermined position when not moving, that is, during plating processing. This locking means 420 is attached to the leg frame 42 as shown in FIG.
Lock lever 4 is rotatably provided at the front and back of 8.
21 and a lock pin 423. When the lock lever 421 is rotated downward, the lock pin 423
is removed from the lock hole, and the press device 422 becomes movable. The suspension vertical movement means 445 and the press block 446 are treated as one unit, and are provided on the girder frame 447 according to the number of parallel units of the plurality of parts to be plated 103 as described above.
All units have the same structure, and only the left and right units are shown in the figure, and one of these units will be explained below.

The hanging vertical movement means 445 is the pressure cylinder 4
53, a pair of front and rear guides 454, and a pair of front and rear guide bars 455.
In the illustrated example, an en-air cylinder is employed as the pressure cylinder 453, and is fixed to the girder frame 447 via mounting bolts 456.
A guide bar 455 is arranged to ensure smooth lowering of the press block 446, smooth return upward movement, and uniform pressing force.

The press block 446 is suspended and supported by the lower end of the rod 457 of the pressure cylinder 453 and the lower ends of the pair of front and rear guide bars 455, and is provided with a base plate 458 on the upper surface side and a pressing portion 459 on the lower surface side. base plate 458
A lock bar 461 with an inclined engagement surface 460 is fixed to the lower surface of the front end with a mounting screw 462, and another mounting screw 463 is fixed to the lower surface of the rear end in the direction of pressing the pressing part 459 to the lock bar 461. It is provided. On the other hand, the pressing part 459 has a reverse inclined engagement surface part 465 on the upper edge of the front end of the pressing part main body 464, which corresponds to the previous inclined engaging surface 460, and a pressing surface part made of an elastic material on the lower surface side of the pressing part main body 464. 466. The press block 446 has a base plate 458 on the upper side, and the entire pressing part 459 on the lower side can be replaced to correspond to the planar size of the plated object 103. It has an overall shape like this. Very narrow plating 103
In the case of complying with item b, as shown in FIG. 17, a "T" shaped pressing part 459 may be used, in which the parts other than those fixed by the base plate 458 are removed. In either case, the plating object 103 has a plating object mounting portion 426 (see plating device main body 220) having an area corresponding to the planar size of the plating object 103 and a similar pressing surface portion 466, in the vertical direction.
When plating, the transfer device 200 that transfers the plating object 103 onto or taking out the plating object 103 is pressed [the pressing surface of the press device 422 against the plating object placement section 426]. 466
When the transfer device is pressed], a space 467 for the movement of the transfer device is formed so that the transfer device can enter or exit between the press device 422 and the plating device main body 220 regardless of the press device 422 or the plating device body 220.

Next, the action will be explained.

During the plating process, the chuck 242 of the transfer device 200 transfers the plating object 103 to the plating object placement section 426 of the upper lid 425. That is, 10 pieces of plating
3 is made free by the rotation of the claw 334 of the chuck 242 and falls under its own weight, and the positioning pin 42
6a, it is accurately positioned on the upper surface of the plating object mounting section 426. At this time, the suspension vertical movement means 445 functions, and the pressure cylinder 453 presses the press block 446 (directly presses the pressing surface 466 of the press block 446), and presses the plated object 103.
While pressing against the upper surface side and continuing to apply pressing force, the plating liquid injection opening 4 of the upper lid 425 is sprayed from the plating liquid injection nozzle 435 in the plating box 424.
39. [Specifically, the plating liquid injection opening 439 of the plating object mounting portion 426] is injected with the plating liquid to apply plating to the plating target portion of the plating object 103 exposed there.

As soon as the plating is completed, the press block 446 returns upwards in the opposite direction, and at the same time, the claws of the chuck 321 of the second chuck device 324 on the exit side rotate to cover both left and right sides of the plated object 322 that has been plated. The plated object 322 is held and discharged from the plated object placement section 426 in preparation for transfer of a new plated object (not shown).

When the plating object 103 to be processed changes, for example, when processing a plating object 103b that is narrower than the previous one, the entire press device 422 is locked by its locking means 4.
20 is in a free state, so to speak, and the main roller 4
49 and the sub roller 450, the rail 45
2 to the right in Figures 7 and 8 manually or using an appropriate drive source [move to the position indicated by the imaginary line in Figure 7] to secure a work space above the plating device main body 220. However, the upper cover 425 and nozzle 435 units in each row may be replaced with other units independently. In addition, the pressing part 4 of the press block 446
By loosening the tightening force of the mounting screws 462 and 463, the inclined engagement surface 460 of the lock bar 461
It is sufficient to remove it and replace it with another pressing part 459 with a pressing surface part 466 that is suitable for the narrow width size of the plating object 103b.

Note that such replacement of the press blocks 446 can be done individually by providing a plurality of press blocks 446 independently on the girder frame 447 of the portal base frame 444 in accordance with the number of rows of the plated objects 103. By independently providing a plurality of upper lids 425, it is possible to replace a wide and long plated item on one line in the width direction, and to use a narrow and short plated item on the next line. ...Plated objects 103, 103a, 103b, 103c, 103 of different sizes at the same time
d, and in either case, the press device 422 is connected to the plating device main body 2.
By moving the top cover 425 of the plating device body 220 from above to the entry side or the exit side, the upper cover 425 of the plating device main body 220
Replacement is a very easy task.

Unloading device 500: This will be explained with reference to FIG. 22.

This unloading device 500
is mainly composed of a feed roller group 502, a storage box 504 on a tray 503, and a temporary receiving device 505.

The feed roller group 502 is formed of a plurality of tapered rollers 507 and rubber rollers 508 arranged on the exit side of the post-processing device 314.
2 are arranged and placed and transported in one direction [in the direction of arrow A in FIG. 22].
I am trying to use . Also rubber roller 508
This forms the terminal of the conveyance line, so to speak.
22, and the plated object 3 placed on it
The object 322 to be plated is reliably fed into the storage box 504 by obtaining a large contact resistance force against the lower surface of the container 22 by utilizing the characteristics of "rubber".

The tray 503 has such a feed roller group 502
It is arranged on the exit side of the storage box 504 and can be moved up and down while being supported at both left and right ends by vertical movement means (not shown), that is, the height can be adjusted freely, so that the height of the receiving surface of the storage box 504 is always maintained with respect to the rubber roller 508. The height can be adjusted freely. The storage box 504 has a plurality of trays 50 according to the number of plated items 322 arranged in a row.
3, the wall surface on the feed roller group 502 side is removed and the receiving opening 5
11 and has a box shape with a bottom, left, right and front walls. The upper surface of the tray 503 is sloped downward from the front side (diagonally toward the front in FIG. 22), and each storage box 504 also has a bottom surface 512.
is in an inclined shape, and the plating object 3 is applied from diagonally above.
22 is made easier to receive.

The temporary receiving device 505 receives the storage box 5 from the lower side of the feed roller group 502, specifically the rubber roller 508.
04, the temporary receiving plate 513 can be moved forward and backward in a substantially horizontal direction, and the plated object 322
A plurality of pressure cylinders 514 corresponding to the number of rows of pressure cylinders 514, and a temporary receiving plate 51 attached to the rod of the pressure cylinders 514 and extending in a substantially horizontal direction.
3. Slit 515 of this temporary receiving plate 513
Plated object 32 placed upright inside
The temporary receiving device 505 is composed of a stopper pin 516 for controlling the removal of the plated object 322, and a sensor 517 for checking the passage of the plated object 322, which sends a drive signal to the pressure cylinder 514. Incidentally, like the pressure cylinder 514, a plurality of temporary receiving plates 513, stopper pins 516, and sensors 517 are each arranged according to the number of plating objects 322 arranged in a row. In addition, the tip end 518 of each temporary receiving plate 513 is inclined slightly forward.
It is designed to adapt to the slope of the plating material 322 that is fed in from diagonally above.

Next, the effect will be explained. The plated objects 322 that have been plated and transported on the line from the post-processing device 314 are given straightness by the taper roller 507, and arrive on the rubber roller 508 in an aligned state.
Each is fed into the storage box 504 by a rubber roller 508. At this time, the tray 503 is adjusted in advance to be at an upper position, that is, at a height close to the rubber roller 508, and therefore each storage box 504 also has its bottom surface 512 aligned with the rubber roller 508.
It is placed close to. When the plating object 322 is conveyed from the taper roller 507 to the rubber roller 508, the sensor 517 detects the presence and passing of the plating object 322, and sends a drive signal to the pressure cylinder 514. At the same time, the pressure cylinder 514 moves to the temporary receiving plate. 513 from below the rubber roller 508 through the receiving opening 511 and into the storage box 504.
advance inward. Therefore, the plating object 322 does not separate from the rubber roller 508 and fall, but its front end is temporarily received by the temporary receiving plate 513.
At this time, since the tip 518 is inclined slightly forward and downward, the plating object 322 can be smoothly moved by the rubber roller 508.
It will be transferred onto the temporary receiving plate 513 [from diagonally above]. Next, the pressure cylinder 51
4 retreats, the temporary receiving plate 513 also returns to the left in FIG. 22, and the plated object 322 is delivered onto the bottom surface 512 of the storage box 504. At this time, even if the plating object 322 tries to move to the left in FIG. 22 on the temporary receiving plate 513, it is regulated by the stopper pin 516,
No plating material 322 was taken out from the facility.

The above actions are repeated, and the height of the storage box 504 is gradually lowered along with the tray 503, so that the height of the receiving surface of the plated object 322 is always maintained at a suitable height relative to the rubber roller 508. By doing so, after storing several pieces of plated items 322, the storage box 50 is removed from the tray 503.
4 is removed, the plated items 322 therein are taken out by hand from the receiving opening 511 in a stacked state, so to speak, and the storage box 504 is returned to the tray 503 again, and the above-described operation is repeated. It is something.

(F) Effects of the Invention Since the automatic plating device according to the present invention has the content as explained above, the entire processing line from the loading device to the unloading device,
It is extremely superior in that it can automatically perform plating by feeding and discharging (retrieving) multiple strip-shaped plating objects in parallel at a considerably high speed, and it can also greatly improve its versatility for plating objects of different width sizes. It has a strong effect. Further, the following effects can be expected from each device constituting the automatic plating device, and these effects can be expected to be synergistic with respect to the automatic plating device. That is, regarding the loading device: (a) Since the stacked plated items are lifted by the lifting cylinder and brought into contact with the outside of the bottom surface of the vacuum box body, it is not necessary to use the plated items as in the past to attract and pick up the plated items. There is no need to lower and return the vacuum box body each time, and the vacuum box body only needs to be moved forward and backward in the horizontal and front-back directions, and the feeding speed can be increased accordingly. As the objects are fed to the processing equipment, the number of stacked plating objects decreases, and the height position of the topmost plating object to be taken out changes, with one sheet in each row being lifted. Because it comes into contact with the bottom, suction is reliable regardless of changes in the height of the plating object, and the vacuum box body can efficiently pick up the plating object down to the last one. By removing the device for lowering and raising the vacuum box main body for suction and picking up from the vacuum box device, the overall structure of the vacuum box device on the movable side can be simplified and miniaturized. An intermediate pedestal is placed between the vacuum box and the pre-processing device, and a plate thickness sensor installed in the vacuum box body is used to check whether or not there is excessive adsorption. Objects can be picked up midway on the intermediate pedestal, correcting the problem of two-piece suction, and the vacuum box itself allows for one-piece pickup.
It is possible to more reliably adsorb and take out the plated material, and it is also possible to prevent problems from occurring in the processing equipment to which the plated material is delivered. By adjusting the interval between the belts to match the positioning grooves, it is possible to reliably support plated objects of different widths and place and transport them to the specified position. Since the side is supported by the upper surface of the pair of left and right belts, it is possible to prevent misalignment and to prevent the row from becoming disordered. As a result of the belt being supported at a position above the outer circumferential surface of the roller by the outer diameter of the belt, the chuck of the chuck device, which can move forward and backward on both the left and right sides, can be smoothly rotated. The rotation of the chuck does not take much time to pick up the picked item, and the time can be shortened by that. Since the relative position of the chuck device to the plating device body can be changed at the same time,
Accordingly, the speed of transferring the plating material to the plating device body, that is, feeding and discharging it, can be increased. In addition, the chucks of the chuck device disposed on the frame pick up and hold the left and right sides of the plating object by rotating, so the plating object can be received without moving up and down.
(j) The chuck device can adjust the distance between the left and right sides of the chuck, so it is versatile for plating objects of different widths, and it The width of each chuck of each chuck can be adjusted independently for each row according to the number of parallel chucks, so it is possible to handle the transfer of plating items of different sizes for each line. By moving from above the plating device body to its entry or exit side, a work space can be secured above the plating device main body, and the top cover of the plating device main body can be easily replaced depending on the type of plating item. (l) Spaces for advancing and retracting the transfer device for supplying and discharging plating materials are formed on both the left and right sides of the plating object that is pressed by the pressing part on the plating object placing part of the plating lifting lid, so when plating The transfer device can be moved forward and backward separately from the operation of the press device and plating device body,
Feeding the plating material to the plating material placement section of the top lid.
The waste can be processed in a shorter time and the plating processing efficiency can be improved accordingly, and regarding the unloading device; Since it is moved to the bottom surface, the plated items can be stored in the storage box in a stationary state without rattling, and the stacked items can be removed smoothly and reliably. be.
