When the material 102 is supplied to the material supply table 101 by a transport equipment such as a forklift, the first robot 103 transfers one material 102 from the material supply table 101 to the alignment table 105. Transfer. When the position alignment of the workpiece 102 is performed in the alignment table 105, the second robot 106 supplies the workpiece 104 having been aligned to the press 108, and the workpiece 108 is pressed by the press 108. 107) is made.

In the case where the alignment of the metal panel 104 formed in the alignment table 105 is not accurate, the shape of the mold (not shown) of the press 108 and the metal panel 107 do not coincide, resulting in product defects. Or expensive molds may break, requiring precise positioning.

In general, when the material 102 is loaded on the material supply table 101 by a forklift, alignment is performed by manual operation. However, since the material 102 is stacked with a plurality of metal panels, there is a problem in that excessive work is required due to its weight.

In order to improve the problem of manual alignment, the hydraulic cylinder is used to force the material to be aligned, but the configuration is complicated by the additional installation of the power cylinder and other components for driving the hydraulic cylinder. There is a problem of deterioration, there is a fear that damage caused by impact on the side of the material.

It was possible to absorb but similarly had a complicated structure.

In addition, such conventional material alignment and transfer devices have a problem that can not respond to the shape and size of a variety of materials. In other words, the product development cycle is getting shorter and the size and shape of the metal panel supplied to the molding apparatus changes from time to time because the design is diversified to satisfy the needs of the consumers. Since it could not be changed, there was a difficulty in making the structure of the device into a new form every time.

The present invention is devised to solve the problems as described above, the object of the present invention is to quickly and accurately align the material supplied to the metal panel forming system from the transport equipment such as forklift by manual operation to a predetermined position To be able to transfer.

Another object of the present invention is to be able to easily change the alignment position of the alignment device to easily respond to changes in the shape and size of the material.

Yet another object of the present invention is to enable the stacked materials to be easily separated from each other to accurately supply the metal panels one by one.

The position adjusting device 47 of the iron plate separator 40 preferably includes a gear train 47a and a detent 47b.

Preferably, the air blower 49 is mounted at one side of the iron plate separator 40 to inject air to the material 3 side so that the metal plate 3a may be separated during the transfer of the metal panel 3a. In addition, by installing the iron plate separator 40 on the transfer table 20 via the straight guide 42, it is preferable to move the left and right relative to the transfer table 20 to adjust the installation position.

As shown in FIG. 7, the iron plate separator 40 may be installed to be movable on the transfer table 20 via a straight guide 42. The linear guide 42 is fixed to the upper side of the transfer table 20, and the guide block 41c installed below the main body 41 is inserted into the linear guide 42, whereby the main body 41 of the linear guide 42 It is installed to be slidable in the longitudinal direction. In addition, the rear surface of the lower portion of the main body 41 has a clamp 41a coupled to one side of the transfer table 20 and a fixing lever 41b for pressing the clamp 41a to fix the main body 41 to the transfer table 20. Is installed. Accordingly, the iron plate separator 40 is moved from side to side on the straight guide 42 to be fixed to the transfer table 20 by the fixing lever 41b and the clamp 41a to correspond to the size and shape of the material 3 used. The installation position of the iron plate separator 40 can be adjusted.

On the upper side of the main body 41, a slide bar 45 is inserted into the transfer table 20 so as to slide substantially horizontally. On the upper side of the slide bar 45, a gear train 47a is formed in the longitudinal direction thereof, and a detent 47b is provided above the main body 41 front side. The detent 47b is moved up and down in the hollow housing 47f which is bolted to the main body 41, the detent lever 47c which is installed to move up and down above the housing 47f, and the housing 47f. And a spring 47d provided between the latch 47e and the latch 47e and the detent lever 47c.

In the state where the latch 47e and the gear train 47a are engaged, the slide bar 45 can be freely moved to the rear of the main body 41, but cannot be moved forward with respect to the main body 41. Therefore, in order for the slide bar 45 to move forward of the main body 41, the engagement state of the gear train 47a and the latch 47e must be released.

Since the upper end of the latch 47e is elastically supported by the spring 47d so that the above-mentioned detent lever 47c is adjusted, the position of the latch 47e is selectively moved up and down within the housing 47f. When the 47c is adjusted, the latch 47e is moved to the lower side and engaged with the gear train 47a or moved upward to be released from the gear train 47a. Therefore, according to the position adjustment device 47 which consists of such a structure, the position of the slide bar 45 which protrudes toward the front of the main body 41 can be adjusted. One side of the main body 41 is provided with a handle 41d that can be used when the operator adjusts the position of the slide bar 45.

A head portion 45a is formed at the front end of the slide bar 45, and a magnetic floater 43 is installed in front of the head portion 45a. Since the head portion 45a is installed at the front end of the slide bar 45 via the angle adjusting device 48, the magnetic floater 43 is left and right with respect to the slide bar 45 together with the head portion 45a. Rotatable. The angle adjusting device 48 includes an angle adjusting lever 48a, and after adjusting the left and right rotation angles of the magnetic plotter 43 so as to correspond to the shape of the raw material 3, the angle adjusting lever 48a The plotter 43 can be fixed to maintain a predetermined angle.

The magnetic floater 43 is a phenomenon in which the metal panels 3a are bonded by giving the same magnetic properties to the material 3 formed by stacking the plurality of metal panels 3a so that the metal panels 3a repel each other. This is a device that does not occur. In addition, by using the air blower 49 for injecting air to the material 3 together with the magnetic floater 43, the metal panel 3a can be easily separated.

Looking at the operation state of the alignment and transfer device of the metal panel forming system having such a configuration as follows.

Alignment and conveying device 1 of the metal panel forming system is that when the forklift 110 supplies the material 3 while the transfer table 20 is located at the material loading position A, the worker stops the material 3 with the stopper 50. Manually slide to the position to perform the primary position alignment. After the primary position alignment is completed, the roller drive motor 22 is operated to drive the balance roller 21 so that the transfer table 20 is moved along the rail 10 to the material supply position B.

When the transfer table 20 is moved to the material supply position B, the first robot 103 adsorbs one sheet of metal panel 3a from the material 3 on which the primary alignment is made and transfers it to the position alignment table 105. After the secondary alignment of the metal panel 3a is performed on the alignment table 105, the second robot 106 accurately supplies the metal panel 3a to the press 108, and the press 108 supplies The molded metal panel 3a is molded.

Fig. 10 shows a use state diagram showing a state in which materials are loaded on the transfer table.

As described above, the size and shape of the material supplied to the molding system can vary from time to time, according to the present invention can easily change the alignment position corresponding to the material of various sizes and shapes.

Since the size of the forklift 110 used depends on the size of the material 3 to be loaded on the transfer table 20, the width X of the fork 110a for conveying the material 3 may also vary. . Since the variable support 35 of the alignment table 30 is movable to the left and right with respect to the transfer table 20, the left and right positions of the variable support 35 are adjusted to match the width X of the fork 110a of the forklift 110. By adjusting the workpiece 3 can be loaded at an appropriate position for the primary position alignment operation.

After the position of the variable support 35 is properly adjusted, the forklift 110 loads the material 3 on the upper side of the alignment table 30, and the loaded material 3 is variable with the fixed support 31. Since the slide roller 37 is supported by the slide roller 37 on the upper side of the support 35, the operator can manually move the material 3. Therefore, the primary position alignment of the workpiece 3 is performed by moving the workpiece 3 until the worker comes into contact with the stopper 50 behind the transfer table 20.

The operator operates the position adjusting device 47 and the angle adjusting device 48 of the iron plate separator 40 before performing the primary position alignment operation, so that the magnetic plotter 43 of the iron plate separator 40 is formed of a material ( The position and angle can be adjusted to face the side of 3).

Since the iron plate separator 40 installed on the upper side of the transfer table 20 is installed on the straight guide 42 so as to be movable in the left and right directions, it is located at the rear of the transfer table 20 in accordance with the left and right widths of the material 3. After adjusting the lateral position of each iron plate separator 40, it is fixed to a predetermined position of the transfer table 20 using the fixing lever 41b. In addition, when the detent 47b provided above the main body 41 of the iron plate separator 40 is released from the slide bar 45 and the gear train 47a, the slide bar 45 is movable relative to the main body 41. The bar 45 is moved to the front of the transfer table 20 so that the magnetic floater 43 protrudes from the stopper 50, and then the detent 47b and the gear train 47a are fixed. Further, by operating the angle adjusting lever 48a of the angle adjusting device 48, the rotation angle is adjusted so that the front end surface of the magnetic plotter 43 corresponds to the shape of the raw material 3.

After adjusting the position and angle of each iron plate separator 40 in this way, if the material 3 is pushed manually, the material 3 is moved to the rear of the transfer table 20 by the slide roller 37, and the material 3 ) Is pressed against the front end surface of the magnetic floater 43. The slide bar 45 is engaged with the detent 47b so that it cannot move forward with respect to the main body 41, but can move backward. Therefore, when the material 3 presses the magnetic floater 43, the slide bar 45 moves backward with respect to the main body 41 until the rear surface of the material 3 contacts the stopper 50.

When the primary position alignment of the material 3 is completed through the above-described process, the roller driving motor 22 is operated to drive the bogie roller 21 so that the transfer table 20 moves along the rail 10 to the material supply position. Move to B

11 is an operating state diagram showing a state in which the iron plate separator is operated.

When the transfer table 20 is moved to the material supply position B, the magnetic floater 43 of the iron plate separator 40 is operated to separate each metal panel 3a of the material 3 from each other. The magnetic plotter 43 imparts a magnetic force to the material 3 to cause the same magnetic polarity on each of the stacked metal panels 3a so that a repulsive force is generated between the adjacent metal panels 3a. ).

Simultaneously with the operation of the magnetic plotter 43, the air blower 49 is operated to inject air into the material 3 from the air nozzle 49a of the air blower 49, thereby separating each metal panel by the repulsive force. The gap between (3a) is maintained so that the metal panel 3a can be easily removed.

According to the alignment and conveying apparatus of the metal panel forming system of the present invention as described above, the material supplied to the metal panel forming system from a transport equipment such as a forklift can be quickly and accurately aligned by manual operation to transfer to a predetermined position. Can be.

In addition, since the alignment position of the alignment device can be easily changed, the shape and size of the material can be easily changed, and the stacked materials can be easily separated from each other so that the metal panels can be accurately supplied one by one.
