2. Description of the Related Art In a plate material processing apparatus such as a punch press, when a plate material carried onto a work table is positioned at an origin position, generally two adjacent sides of the plate material are end locators. And the work holder. The end locator is composed of a pin or the like that projects from the work table.
The work holder is provided on the cross slide or the like of the plate material feeding mechanism and holds the end portion of the plate material. However, the external shape of the plate material that is the material may not have sufficient accuracy, and when the plate material processed in the previous process is carried into the subsequent process and processed differently, it is added to the end locator etc. as described above. With the method of pressing two sides of the outer periphery of the plate material, it may not be possible to perform accurate positioning.

For example, when a large number of plate products are taken from a material plate by punching, and then a joint portion connecting each plate product and the surrounding residual material is carried into a device dedicated for cutting and punching and cutting, etc. Accuracy matters.
That is, when a large number of plate products are taken from a material plate by punching, generally, as shown in FIG.
As shown in (A), each plate material product W ₁ , W ₂ is punched by leaving a cross-shaped joint J called a micro joint between each plate material product W ₁ , W ₂ and the surrounding residual material S. I do. This joint part J is generally separated by a sub head equipped in a punch press or manually. However, in order to improve the efficiency of punch processing, the applicant of the present invention separately installs a separate device for separation. Proposed. However,
When punched plate material is carried into this cutting device, if two edges of the plate material are pressed against the end locator, etc., as in the punch press in the previous process, the positioning accuracy will be sufficient. Since it is not present, an error occurs in the cutting position of the joint portion, making it difficult to finish the cutting line on the outer periphery of the product neatly. Incidentally, in the conventional laser processing machine, the reference hole previously provided in the plate material is imaged by the camera,
It has been proposed that the feed amount of the NC device is corrected so that the plate material is fed in accordance with the center of the reference hole by image processing (Patent Publication 6-77864). According to this, highly accurate processing can be performed. However, there is a problem that the configuration becomes complicated because a camera and an image processing device are required.

The present invention solves these problems, and an object of the present invention is to provide a plate material positioning device having a simple structure capable of eliminating a machining error between a pre-process and a post-process.

For example, if the reference hole (112) is formed at the time of punching, which is a pre-process, the reference hole (112) is more accurate than the pre-process apparatus, and the reference hole (11)
Since positioning is performed by the post-process device with respect to 2), it is possible to eliminate a processing error between the pre-process and the post-process. Further, even if the reference hole (112) is formed prior to the previous step and both the pre-process device and the post-process device are positioned by the reference hole (112), the pre-process and the post-process will be performed. Processing error can be eliminated. On the other hand, since the positioning by the reference hole (112) is performed by the engagement of the origin setting member (113), the structure is simple. It should be noted that the origin setting member (113) may be fixed in position or may be capable of being fed, and may be moved to a predetermined position and positioned after being engaged with the reference hole (112). good. When the origin setting member (113) is provided so as to be retractable, it is possible to prevent the plate material from being obstructed by retracting it below the table surface after positioning. When the origin setting member (113) is a tapered pin and the retracting device (114) is provided, a reference hole (W) is attached to the plate material (W) placed on the work table (72) with a rough accuracy. By inserting the origin setting member (113) into the inside of (112) by an ascending operation, the plate material (W) is guided by the tapered surface of the origin setting member (113), and the reference hole (112) is formed at the center of the origin setting member (113). The position is corrected so that the centers of) are the same. Therefore, positioning can be performed easily and accurately. In this case, the plate material (W) is moved along with the rise of the origin setting member (113).
Is prevented from being pushed up by the floating stopper member (120) coming into contact with the plate material (W) in the vicinity of the origin setting member (113), and reliable positioning can be performed.

At the skeleton box standby position Q2, a skeleton box mounting table 242 having pallet mounting rails 242a on both sides of the upper surface is installed.
The box loading pallet 11A is placed on a. As shown in FIG. 38, stoppers 246 that can be engaged with and disengaged from the positioning protrusions 245 provided on the skeleton box mounting table 242 are swingably provided at the front and rear ends of the box loading pallet 11A. The stopper 246 is also used for locking the internal pallet P of the automated warehouse 1. 36 to 38 are provided around the skeleton box mounting table 242.
2, sensors 247 and 248 for detecting the box loading pallet 11A, a sensor 249 for detecting the presence / absence of a load in the skeleton box 13, and sensors 252, 253 for detecting the skeleton box 13 are provided.

The operation of the entire equipment having the above configuration will be described. The material pallet 11 carried out from the automatic warehouse 1 to the laminated plate material carrying-out device 2 is drawn out to the drawing end on the device 2 and stands by. The material plates W stacked on the material pallet 11 are adsorbed and conveyed one by one by the material loader 3 that travels in the left-right direction along the outward rail 23, and are moved to the origin position on the work table 35 of the punch press machine 4. Is brought in.

In the punch press machine 4, for example, as shown in FIG. 39 (A), a blank plate material W is subjected to outline punching of large and small products W ₁ and W ₂ . At this time,
Each of the products W ₁ and W ₂ is not separated from the material plate material W, and a cross-shaped joint portion J is left in a part of the contour hole H to be connected to the skeleton-shaped residual material S on the outer periphery. Also,
Along with the punching of the products W ₁ and W _{2, at} the portion which becomes the skeleton-shaped residual material S of the material plate material W, four long slots A for transportation A
~ D and two reference holes 112 are punched. The plate material W that has been punched is lifted from the reference position on the work table 35 by the plate material loader 5 that travels in the left-right direction along the outward rail 23, and the reference material on the work table 72 in the adjacent plate material processing device 6 for separating. It is lowered to the position. The plate material W is conveyed by the plate material loader 5 by the hook 54.
Then, the plate material W is lifted up. When lifting from the punch press machine 4, the plate material loader 5 moves each hook 54 to the lifting frame 4
9 along with each of the long holes A to D for conveyance of the plate material W as shown in FIG.
Insert like. At this time, the transporting long holes A to D of the plate material W at the reference position are aligned with the respective hook escape holes 99 of the work table 35, and the hooks 54 can enter the hook escape holes 99, Interference with 35 is avoided. When the plate material W is of the large size of the two types shown in the figure, the hook 54 at the intermediate position dedicated to hooking the small size plate material is changed by the hook changing means 62 (FIG. 8B). The hook 54 is raised and retracted slightly above so that it does not interfere with the upper surface of the plate material W. In this way, the hook 54 is attached to the long hole A for transporting the plate material W.
After being inserted into ~ D, each hook 54 is rotated by 90 ° by the hook engaging / disengaging device 56 as shown by the chain line in FIG. As a result, each hook 54 is engaged with the back surface of the plate material W at the edge of each corresponding long slot for conveyance A to D of the plate material W. After that, the elevating frame 43 moves up and the loader body 41 travels, so that the plate material W is conveyed to the plate material processing apparatus 6 for separation.
Since the plate material W is lifted and conveyed in this manner, the plate material W can be conveyed without damaging it. In addition, the plate material W is hooked 5
Since it is hooked and lifted by 4, unlike the vacuum suction pad and the magnet type suction tool, it can be lifted even if the contour hole H or the like is clear and the plate material W is a non-magnetic material such as aluminum or a plastic plate. . Further, since the pair of diagonal holes A and B of the plate material W are elongated holes extending in the lateral width direction of the plate material W, there is little play in the front-back direction of the hooks 54 in these elongated holes A and B, and the plate material W is small. The positional displacement in the front-back direction is prevented. In addition, another pair of holes C and D having a diagonal relationship.
Is a long hole extending in the front-rear width direction of the plate material W, so that there is little play in the left-right width direction of the hooks 54 in the long holes C and D, and displacement of the plate material W in the left-right width direction is prevented.
Therefore, the plate material W can be stably transported without being displaced in any of the front, rear, left, and right directions, and the hook 54 does not accidentally come off. In addition, it can be transported to an accurate position.

The plate material W conveyed by the plate material loader 5 to the separating plate material processing device 6 is lowered to a reference position on the work table 72. At this time, the origin setting member 11 of the work table 72 stands by at an intermediate protruding position slightly protruding from the upper surface of the table, and by lowering the plate material W at the reference position, the leading end of the origin setting member 113 becomes the reference hole 112. Fit in. The long slots A to D for transporting the plate material W are located on the hook escape holes 111 of the work table 72. The cross slide 117 of the plate material feeding device 73 stands by at the origin position in the X-axis direction, and the work holder 119 stands by at a position where the plate material W can be gripped by a slight advance. In order to prevent the floating member 120 from hindering the lowering of the plate material W, the floating plate 124 is retracted into the guide member 123 as shown by the chain line in FIG. After the plate material W is unloaded, the floating stopper plate 124 is advanced to the upper surface of the plate material W up to the origin setting member 113. After that, the origin setting member 113 protrudes to the rising end.
With this projecting operation, the opening edge of the reference hole 112 is guided by the tapered surface of the origin setting member 113, so that even if the reference hole 112 of the plate material W is slightly deviated from the center of the origin setting member 113, the error is corrected. Thus, the plate material W is accurately positioned at the origin position. At this time, the origin setting member 1
The plate material W may be caught on 13 and a lifting force may be applied to the plate material W, but since the plate material W is held by the floating member 120, the plate material W is prevented from rising. After the plate material W is positioned in this manner, the work holder 119 moves forward together with the carriage 73 and advances to the plate material W.
After the origin member 113 is lowered below the surface of the table, the hooks of the hooks 54 with respect to the transporting long holes A to D are released by a rotation operation opposite to that at the time of lifting.

In the plate material processing apparatus 6, in the plate material W thus loaded, the joint part J left in the product contour hole H is punched and cut by the punching tool 77 of the joint part punching mechanism 78, and the plate material W is removed from the plate material W. The products W ₁ and W ₂ are separated. Each time one of the products W ₁ and W ₂ is separated, the product transfer device 7 causes the product storage box 12 to store the product W ₁ ,
W ₂ is collected. At this time, in case of big product W ₁ ,
It is magnetically attracted and lifted by the large object transfer device 8,
The product is conveyed to the top of the plate removal reproduction table 19 which is in a closed state above the product storage box 12. By repeating this operation, each large product W ₁ is placed on the plate making reproduction table 19 as shown in FIG.
As shown by the solid line in (B), they are arranged in a layout relationship during plate cutting. Positioning the large product W _{1 in} the front-rear direction (Y-axis direction) on the plate removal reproduction table 19 is performed by adjusting the traveling distance of the large object transfer device 8, and positioning in the left-right direction (X-axis direction) is performed. This is performed by moving the flexible mounting table 19a. When all of the large products W ₁ are placed on the plate removal reproduction table 19, the large product transfer device 8 sucks and lifts all the large products W ₁ at a time in the arrayed state, and the plate removal reproduction table 19 is lifted. Open 19 After that, the product storage box 12 is lifted above the plate removal reproduction table 19 by the lifting / lowering device 176 of the trolley 175, and the whole large product W ₁ is lowered from the large product transport device 8 onto the product storage box 12. In this way, all the large products W ₁ are placed in the product storage box 12 in the arrangement in the planing state. In this way, the product W
When lowering ₁ into the product storage box 12, all the ascending / descending frames 195 by group are connected by the ascending / descending frame connecting device 202 and moved up and down integrally, and due to the speed difference between the ascending / descending frames 195 by group, the large product W Prevents the adsorption of ₁ from coming off. As described above, by using the plate removal reproduction table 19, it is possible to easily store the plate removal state in the product storage box 12 which is difficult to store directly in the plate removal state. In addition, the large object transport device 8
As described above, since the large product W ₁ is conveyed in the air as described above, it is less likely to be damaged as compared with the case where the large product W ₁ is conveyed on a shooter or a roller conveyor. Further, since the product is adsorbed from above, the floor space can be small.

On the other hand, the suction tool 182A of the large object transfer device 8,
Small product W that cannot be adsorbed with the arrangement density of 182B
_In the case of ₂ , the small-piece conveying device 9 conveys the small-piece conveying product to the position of the product positioning device 17. That is, the product discharge shooter 131 located below the cutting processing head 81.
Is inclined downward, and the small product W ₂ is dropped onto the belt conveyor 146 through the product discharge shooter 131 and the product discharge secondary shooter 147, and the small product conveyance product positioning device 17 installed at the end position by the belt conveyor 146. Mounted on the tilting table 148. The tilting table 148 is shown in FIG.
23. As shown by the chain line in FIG. 1 (B), it descends and leans toward the front right corner side, whereby the small product W ₂ is positioned at the front right corner of the tilting table 148 as shown by the chain line in FIG.

After the positioning, when the tilting table 148 is returned to the original horizontal posture by the returning drive by the tilting drive cylinder 149, the tilting table 148 is moved by the suction storage device 18.
The small product W ₂ positioned at is adsorbed and lifted, and is moved in the front-rear direction and lowered to be placed on the product storage box 12 in the plate-cutting state as shown in FIG. 39 (C). To be done. Since the suction storage device 18 sucks the small product W ₂ positioned on the tilting table 148 in this manner, reliable suction can be performed. The front-rear position of the small product W ₂ on the product storage box 12 is determined by the movement of the suction tool attachment body 161, and the lateral placement is determined by moving the cart 175 on which the product storage box 12 is placed in the left-right direction. By. Also, at this time, the trolley 1
75 lowers the lifting table device 176 so that the product storage box 12 has substantially the same height as the tilting table 148. It should be noted that, as shown in FIG. 39, the small products W ₂ are gathered forward and the small products W ₂ are stored in the product storage box 12 when the small products W ₁ and the small products W ₂ on the plate material W are removed. It is desirable to be performed before the large product W ₁ .

The skeleton-shaped residual material S obtained by separating the products W ₁ and W ₂ is crushed into small pieces of slag by repeating the punching operation by the punching tool 77 of the slag punching mechanism 80 and the feeding operation of the plate material feeding device 73. The slag discharge shooter 132 located below the slag head 82 is tilted downward and collected in a slag collecting truck (not shown) or the like. As described above, in the plate material processing apparatus 6, the processing head 8 dedicated for cutting off the product is used.
The slag head 82 is used for crushing slag.
Therefore, the life of the punching tool 77 of the cutting processing head 81 can be significantly extended.
