Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material processing apparatus.

[0002]

2. Description of the Related Art For example, for a large metal plate such as a stainless plate, it is often required to cut each corner in a curved shape and then deburring and polishing the peripheral edge. Conventionally, when performing such processing, an operator first goes to a place where unprocessed plate materials are piled up, takes out the topmost sheet from here, and carries it to a processing site at a corner. At this site, for example, an R-cut process is performed using a simple press device or the like, and when the process is completed, the R-cut process is carried out to the peripheral edge polishing process. In the polishing process, a hand-held grinder is used to grind while walking along the periphery of the plate material. Thus, when a series of work is completed, it is carried out as a processed plate material.

As described above, conventionally, each of the corners and peripheral portions of the plate material is manually processed, and setting and removal to / from the work table in preparation for performing these operations are also manual work. Transfer between processes was also manual work.

[0004]

As a matter of course, in such continuous manual work, the working time until the completion of processing is long and the efficiency is extremely low. In addition, dust is scattered at the site where the grinder is injured, which creates an unfavorable environment for workers entering and leaving.

The present invention has been developed and devised in view of such circumstances, and an object thereof is to improve work efficiency and work environment by automating a machining process.

[0006]

The structure of the present invention for achieving the above object comprises a stock table for mounting an unprocessed plate material, a punching press device for corner-cutting a corner of the plate material, A chamfering device for chamfering the peripheral edge of the plate material is sequentially arranged, and an automatic transfer device for automatically transferring the plate material is provided above the stock table, punching press device and chamfering device. It is characterized by being present.

[0007]

The unprocessed plate material is transferred from the stock table to the punching press device by the automatic transfer device, where the corners are cut. When this process is completed, the plate material is transferred to the chamfering device by the automatic transport device, and is automatically carried out to the outside after the completion of this process.

[0008]

The effects of the present invention are as follows. Since a series of processes from taking out from the stock table, corner cutting, and further chamfering to carrying out is automated, work efficiency is improved. In addition, the worker is kept away from an unfavorable environment such as dust, which contributes to the improvement of the working environment.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a plan view showing the entire processing apparatus of the present embodiment. A stock table A on which an unprocessed plate material W is placed, a punching press device B for corner cutting the corners of the plate material W, and a plate material in order from the left in the figure. The chamfering device C for chamfering the peripheral portion of W and the product table D for stacking the processed plate materials W have a line structure. As shown in FIG. There is provided a transfer device H for automatically transferring the plate material W.

The stock table A is provided with a sensor for detecting the presence or absence of the plate material W.

First, the punching press device B will be described with reference to FIGS. 3 to 5. The device B is a work table 1 and a pair of press units arranged on both upper sides of the work table 1 in FIG. It consists of a few. Of these, the work table 1 is provided with a table plate on the upper surface of the base 4, and a large number of small holes 5 are formed in the entire area thereof. These can be selectively communicated with a blower and a vacuum pump (not shown) via solenoid valves, and the plate material W can be freely moved on the work table 1 by the air blown while communicating with the blower. Become. On the other hand, when the switching operation is performed so as to lead to the vacuum pump,
The plate material W is suction-fixed on the work table 1. However, in order to correspond to the size of the plate material W, by operating the manual valve, it is possible to validate only the small holes 5 in the desired region among the small holes 5 formed in the entire area of the work table 1. it can.

Further, two pusher mechanisms 6 composed of air cylinders are provided on the work table 1, and have a role of moving the plate W upward in FIG. 3 and performing positioning in this direction. Fulfill Positioning in the horizontal direction will be described later. However, both pusher mechanisms 6 can be replaced at arbitrary positions on the work table 1 so that the plate materials W having different sizes can be accommodated.

The press units 2 and 3 arranged at the left and right positions in FIG. 3 both have a function of corner-cutting one corner of the plate material W into a curved shape, but the structure itself is known. Therefore, the description of each configuration is omitted. However, in this example, the one arranged on the left side in FIG. 3 is the fixed press unit 2, whereas the one arranged on the right side is the movable press unit 3, and the plate materials W having different sizes are used.
It can be adapted to. That is, the movable press unit 3 is assembled on the orbit laid in the left-right direction shown in FIG. 3, and together with the positioning portion 7 provided integrally on the side portion of the unit 3 in an overhanging manner, the operation handle. The rotation operation of 8 guides the movement in the left-right direction in FIG. That is, the distance between the press units 2 and 3 can be adjusted in advance according to the size of the plate material W (so as to be slightly larger than the width of the plate material W).

Further, in the punching press apparatus B of this example, two adjacent corners of the plate material W are processed in one step, and the remaining two points are later set in a 180 ° inverted state. It is set to be processed again. Furthermore, in detail, the corner cuts at two locations are not performed at the same time. Instead, one of the press units (the fixed press unit 2 in this example) precedes the processing, and then the other press unit (the movable press unit). Processing according to 3) is performed. Therefore, the work table 1 is provided with a mechanism (positioning mechanism in the left-right direction) for displacing the plate W in the left-right direction in FIG. That is, the side edges of the plate material W are sequentially positioned one by one to perform the processing, thereby making it possible to make the curvatures of the corner cuts uniform.

Next, the chamfering device C will be described with reference to FIGS. 6 to 8. The chamfering device C is a work table 9 and a first polishing unit 16 provided below the work table 9 in FIG. And a second polishing unit 17 provided on the right side of the work table 9.

As with the punching press device B, the work table 9 has a large number of small holes 1 which can selectively communicate with a blower and a vacuum pump (neither is shown).
2 is open and can be moved and fixed to the plate W. Further, a total of four pusher mechanisms 13 including air cylinders for pushing the plate material W in the X and Y directions are provided on the upper surface thereof so that the respective mounting positions can be changed. An X-direction guide mechanism 14 and a Y-direction guide mechanism 15 are provided on the work table side in order to receive the plate material W pushed by each pusher mechanism 13 and position the plate material W in both X and Y directions. There is. The both guide mechanisms 14 and 15 perform an operation position in which the plate material W can be positioned with respect to the plate material W in a state of slightly protruding from the work table 9 and a polishing operation by the first and second polishing units 16 and 17 described later. It is configured to be able to move to and from the retracted position where the workpiece table 9 is retracted to avoid the interference with these during the break.

The pusher mechanism 6, the X-direction guide mechanism 14 and the Y-direction guide mechanism 15 described above cooperate with the small holes 12 of the table plate so that the processing portion of the peripheral edge of the plate material W is adjacent to the work table 9. It functions as a plate material positioning and fixing means for positioning and fixing so as to be in a predetermined state of protruding from the two side edges.

The first polishing unit 16 is the base frame 1
8 is mounted on a movable frame 20 movable along a guide rail 19 laid on the upper surface of the work table 8, and along one side edge portion (lower side edge portion in FIG. 6) of the work table 9 in FIG. Can be moved left and right. Also, the moving frame 2
No. 0 is provided with a dust collector 21 together with the first polishing unit 16 so that the dust scraped from the plate material W by the belt polishing mechanism 22 and the foil polishing mechanism 23 can be collected and removed from the air. ing. The belt polishing mechanism 22 is composed of an endless sanding belt that can be driven by a motor (not shown), and plays a role of polishing the straight portion of the side edge of the plate material W. on the other hand,
The wheel polishing mechanism 23 is provided with a sanding wheel having a large number of polishing pieces provided on the periphery of a rotary base, and these can be rotationally driven by a motor (not shown). Further, the wheel polishing mechanism 23 is configured to be capable of advancing and retracting, which enables polishing along the curvature of the corner of the plate material W.

Unlike the first polishing unit 16, the second polishing unit 17 does not have the foil polishing mechanism 23,
Only the belt polishing mechanism 22 is provided. The polishing unit 17 is also provided with the base frame 10 and can be moved along the guide rail 11 laid on the base frame 10. Further, 17a is a dust collector.

However, in order to prevent the polishing units 16 and 17 from interfering with each other at the lower right corner in FIG. 6, the movement timing of one polishing unit is delayed and the movement of the other polishing unit is started beforehand. It is carried out at the timing given.

Explaining the transfer device H, a transfer rail 24 is horizontally installed above the stock table A, the punching press device B, the chamfering device C, and the product table D. A self-propelled device (not shown) is mounted below the carriage frame 25 so that it can roll on the transport rail 24. A support board 26 is suspended and supported by the carriage frame 25, and the support board 26 is connected to an elevating cylinder 27 so that it can be moved up and down. Further, the support board 26 has a plurality of suction pads 28 capable of suctioning and releasing the plate material W.
Is provided. However, the operation of the carrier device H is performed according to a preset procedure. This will be described in detail by the following operation (FIG. 9).
reference).

First, an operator sets the origin for the punching press device B and the chamfering device C prior to the work.
The dimensions of the plate material W to be processed are input to the control device via an operation panel (not shown). Further, the pusher mechanisms 6 and 13 are attached at appropriate positions according to the size of the plate material W, and the small holes 5 of the work tables 1 and 9 in both the devices B and C are further attached.
The areas to be activated for the 12 groups are switched.

When the above initial setting is completed, the machining operation proceeds according to the pattern diagram shown in FIG. In the figure, A is a stock table A, B is a punching press device B, C is a chamfering device C, D is a product table D, E is an intermediate withdrawal position (a position shown by an imaginary line in FIG. 1), and ◯ indicates adsorption of the plate material W by the transport device H, X indicates its release state, and no mark indicates the standby state.

Now, first, the support board 26 of the transfer device H descends, and the uppermost plate material W stacked on the stock table A is adsorbed by the adsorption pad 28. Then, the plate material W is lifted by the lifting cylinder 27 and transferred to the punching press device B. Plate material W is the same device B
While being lowered onto the work table 1 and the two corners thereof are being corner-cut, the transfer apparatus H stands by at a position above the apparatus (Pattern 1 in FIG. 9).

The plate material W lowered onto the work table 1 of the punching press device B is in a state in which it can move freely because the air from the blower is initially supplied from the small holes 5 group. At this time, the pusher mechanism 6 performs positioning in the vertical direction in FIG. 3, and the plate material W is pressed against the reference edge on the fixed press unit 2 side by a not-shown biasing mechanism to position and fix in the horizontal direction in FIG. . In this state, the fixed press unit 2 is operated to cut one corner of the plate material W into a curved shape, and when this is finished, the plate material W is pressed against the reference edge on the side of the movable press unit 3 by the one-sided moving mechanism, and the above-mentioned is performed. The edge on the side opposite to is positioned and fixed, and in this state, the corner on the opposite side is cut by the movable press unit 3.

Thus, when the punching press working on the two corners is completed, the carrying device H is operated according to the procedure of pattern 2. That is, the support board 26 descends again, and the plate material W whose two corners are corner-cut is lifted as it is, transferred to the chamfering device C, and lowered onto the work table 9 of the device C. After that, the transport device H
It moves to the stock table A, lifts the plate material W on the table A, and conveys it to the punching press device B. Therefore, from this point onward, the punching press process and the chamfering process proceed in parallel, and during this time, the transport device H stands by at the upper position (intermediate retreat position E) between the punching press device B and the chamfering device C. And wait for the completion of chamfering.

In the chamfering device C, the plate material W is placed on the work table 9, and the pusher mechanism 13, the X-direction guide mechanism 14 and the Y-direction guide mechanism 15 project the plate W from the two side edges adjacent to the processing portion of the peripheral edge. It will be positioned and fixed in this state. Prior to the polishing operation, the guide mechanisms 13 and 14 are moved to the retracted positions (not shown) to avoid interference with the polishing units 16 and 17.
The first and second polishing units 16 and 17 are the guide rails 1.
The edges of the plate W are polished while moving (reciprocating motion repeated a predetermined number of times) along 9 to avoid mutual interference, but both corners of the corner cut are removed by the wheel polishing mechanism 23. Polishing is performed, and the other straight portions are polished by the belt polishing mechanism 22 of both polishing units 16 and 17.

When the chamfering process is completed as described above, the transfer device H moves from the intermediate retreat position E to the chamfering device C according to the pattern 3 and sucks the chamfered plate material W to the product table D. And place it. And
The transport device H returns to the punching press device B, and the operations of pattern 2 and pattern 3 are repeated thereafter. When this operation is repeated and the sensor detects that the last plate material W has been transferred from the stock table A,
After that, the operation procedure of the transport device H shifts to the pattern 4, and the last plate material W is sequentially sent to the punching press device B and the chamfering device C, and stacked on the product table D.

Thus, all the plate materials W have moved onto the product table D, but the processing up to now is for the two side edges of the plate material W, and the other two side edges are unprocessed. This part is repeatedly processed in accordance with the above pattern, and therefore, when the worker moves the plate material W from the product table D to the stock table A on a work trolley or the like, all the plate materials W are previously processed. It is set on the stock table A while being rotated 180 ° from the above state. By this repeated processing, the processing of the plate material is completed, and the product is taken out as a product.

As described above, according to the carrying procedure of this example, it is possible to simultaneously perform two steps (steps for corner cutting and steps for chamfering) in parallel, and to wait as much as possible. Since it will be solved, the improvement of work efficiency can be expected. Further, since each process of both corner cutting, chamfering, and conveyance is automated, work efficiency can be dramatically improved as compared with the conventional manual work. Further, the chamfering device C is provided with the dust collecting device 21 to alleviate the situation in which dust is scattered around the surroundings, and since it is not necessary for the worker to be particularly close to the chamfering device C, an environment suitable for working hygiene can be created.

The means for rotating the plate material W by 180 ° can also be carried out by the transport device H, and the operation pattern in this case is shown in FIG. In this case, the transport device H is the support board 2
It is necessary to mount a reversing motor or the like so that 6 can be reversed 180 ° in the horizontal plane.

First, in the pattern 1, the transport device H uses the plate material W.
Is moved from the stock table A to the punching press device B. When the corner cutting of the two corners of the plate material W is completed, the transport device H sucks and lifts the plate material W. Then, after rotating at that position by 180 °, the plate material W is lowered onto the work table 1 of the punching press device B again, and above the device until the processing is completed.
stand by. In the pattern 2, the transfer to the chamfering device C is performed after the cutting processing on the four corners of the plate material W is completed as described above. After that, the transfer device H moves from the chamfering device C to the stock table A, and from there, the second unprocessed plate material W is lifted and transferred to the punching press device B. Then, when the two corners are cut, the transport device H lifts the plate material W to 180 °.
It is rotated and returned to the punching press device B again so that the remaining two corners can be cut. After that, the transport device H moves to the chamfering device C, lifts the plate material W whose half-circumferential portion has been chamfered and rotates it by 180 °, and returns to the chamfering device C again to perform chamfering for the remaining half-circle. Lower it. After that, the transport device H retracts to the intermediate standby position and waits for the completion of chamfering. Then, when the processing is completed, the transport device H moves again to the chamfering device C according to the pattern 3, and the plate material W on which all the processing is completed is lifted, transferred to the product table D, and then moved to the punching press device B. Then, the operations of pattern 2 and pattern 3 are repeated. .

When the sensor detects that the last plate material W has been transferred from the stock table A, the carrying device H cuts the plate material W having four corners according to the pattern 4 from the punching press device B to the chamfering device C. Transfer to. Then, when the chamfering process for the entire peripheral edge is completed as described above, it is transferred to the product table D according to the pattern 5, and thus the process for all the plate materials W is completed.

According to such a carrying procedure, all the steps can be automated, so that further improvement in working efficiency can be expected.
