Description

Press material transfer device {A device for transferring workpiece to press}

The present invention relates to a press material conveying device, and more particularly, a press material conveying device capable of inverting and conveying a material during a press process, and rotating 90° when taking out the reversed material in the inverting space to insert it into a mold It is about.

In general, a press that presses metal products or metal parts with upper and lower molds is a process of introducing materials into the mold of the press before and after molding, the molding process of press forming the material brought into the mold, and the press-molded material. Since the carrying-out (discharging) process of discharging from the mold and the transfer process of transferring the taken-out material to the mold of the next molding process are involved, a press material transfer device is used that adsorbs and transfers, carries in, and takes out the material between presses.

As an example of such a press material transfer device, there is Patent No. 10-1675714 ("variable transfer for multi-process press system"), which has been filed and registered by the present applicant.

In the conventional "variable transfer for multi-process press system", the material located in the first press between the first press and the second press having different heights disposed adjacent to each other is a support unit through the first suction unit and the first height adjustment unit. It can be placed on the base plate of the base plate, and the material on the base plate can be adsorbed and moved to the second press through the second adsorption unit and the second height adjustment unit, stopping the material between the first and second presses of different heights. Without it, the work could be done in continuous motion.

However, the conventional "variable transfer for multi-process press system" did not have a separate reversing device for processing both sides of the material, so it was impossible to reverse the material during the transfer process, and therefore, an additional reversing facility must be installed. As the process line lengthens, there is a problem that the process progress is delayed by that much.

In addition, in the process of transferring the material, since the first adsorption unit and the second adsorption unit are moved together by the fixed plate moving unit, any one of the adsorption units that is not involved in the carry-in or carry-out plays, and power is unnecessarily lost Occurred.

In addition, when the material is rotated 90° and put into the mold in an erect state, a separate rotating facility must be additionally installed.This also delays the process progress as the fixed line lengthens, and additional costs are required. There was a problem.

Reference numeral '480', which is not described in FIG. 2, is an intermediate transit plate on which the material 3 is seated when transferring the material 3 that does not require inversion in the form of a relay, and is installed on the lower side of the inversion unit 400. Configuration.

From now on, the operation process of the press material transfer device according to the present invention will be described.

<Material import process>

Referring to FIG. 2, press processing is performed on one surface of the material 3 in the first press 10.

When the processing is finished, as shown in FIG. 1, the first Y slider 320, the first arm 330, and the first adsorption unit 340 are pressed by the driving of the first X slider 310. It is horizontally moved by the first distance toward the 10) side.

Then, the arm rod 331 and the first adsorption unit 340 are horizontally moved toward the first press 10 by a second distance by the driving of the first arm 330.

When the adsorption port 342 of the first adsorption unit 340 comes to the material 3 placed on the first press 10, the adsorption port 342 is driven by the first Y slider 320 so that the material ( It approaches and adheres to the surface of 3), and a suction force acts on the suction port 342 to adsorb the material 3.

When the material 3 is adsorbed, the first X slider 310, the first Y slider 320, and the first arm 330 are driven in reverse order, and the material 3 is reversed as shown in the upper side of FIG. Transfer between the units 400.

Conventionally, in the process of transferring materials, since the carry-in unit and the carry-out unit are tied to one moving unit and are moved together, the power is unnecessarily lost and the process is delayed while moving to the unit not involved in the carry-in or carry-out. Occurred.

On the contrary, in this embodiment, as shown in FIG. 1, the carry-in unit 300 and the carry-out unit 500 are driven separately while facing each other with the material 3 in the center, so that the above problem can be solved simply. There will be.

In addition, since the first arm 330 and the first adsorption unit 340 included in the carry-in unit 300 are independently movable independently of the first X slider 310, the first press 10 2 Of the entire horizontal transfer section to the press 20, the first distance will require power required for driving the first X slider 310, and the remaining second distance will require much less power than this, so the power required for the transfer process is minimized. You can get the effect.

To this end, the first adsorption unit 340 adsorbing the material 3 on the first press 10 is first transferred by the first X slider 310 and secondary transferred by the first arm 330 It is preferable that a control unit (not shown) that sequentially controls linear driving of the first X slider 310 and the first arm 330 to reach the reversing unit 400 is further included.

<Material reversal process>

Referring to FIG. 5, when the material 3 is transferred between the reversing units 400, the finger joints 414 of the open finger portions 410 are closed and the material 3 is held.

At this time, if the material 3 is held on only one side, the material 3 may sag and tilt to one side depending on its own weight, so that the position and posture of the material 3 can be accurately maintained. It is advisable to match on both sides.

To this end, the reversing unit 400 is configured in plural and divided into a first reversing unit 401 and a second reversing unit 402, and the first reversing unit 401 and the second reversing unit 402 are formed of a material ( It is installed facing each other with 3) in between, and at the same time, it is driven symmetrically to meet the material 3 from both sides.

When the material 3 is gripped by the finger part 410, the finger part 410 is rotated 180° as the rotation driving part 420 is driven to rotate as shown in FIG. 6, and the material gripped by the finger part 410 (3) is also reversed by 180°.

Conventionally, since a reversing device for double-sided processing of the material was not separately provided, it was impossible to reverse the material during the transfer process, and thus, an additional reversing facility had to be installed and the process progress was delayed by that much.

However, in this embodiment, through a simple process in which the material 3 is handed over during the transfer process and both sides of the material 3 are grabbed by the flexible finger joints 414 of the reversing unit 400 and immediately turned over, it is faster and more stable. There is an advantage of being able to carry out material transfer and reversal operations.

In addition, since this embodiment is not a method in which the material 3 is passed from one side to the other, but a method in which the material 3 is rotated and inverted in place, the space required for the inversion operation can be minimized.

In particular, according to this in-situ reversal method, since the shape of the reversing unit 400 is the same before and after the reversal of the reversal unit 400, the original reversal operation of the reversing unit 400 for the next reversal can be omitted.

That is, after the material carried in first is reversed and carried out to the second press 20, the reverse unit 400 is not reversed again and is newly carried in from the first press 10, and then the material is continuously handed over. By reversing, the transfer and reversal process can be carried out more efficiently.

<Material export process>

Referring to FIG. 2, when the material 3 is inverted by the reversing unit 400, the second X slider 510 of the carrying unit 500 is driven and the second Y slider 520 and the second arm 530 are driven. ) And the second adsorption unit 540 approach the reversing unit 400 side.

Then, while the second arm 530 is driven, the second adsorption unit 540 is positioned on the material 3, and the surface of the material 3 is approached by the driving of the second Y slider 520 It is tight.

When the second adsorption part 540 is in close contact with the surface of the material 3, a suction force acts on the adsorption hole to adsorb the material 3, and the finger part 410 that held the material 3 at the adsorbed height As the material 3 is unfolded, it is possible to carry out the material (3). (At this time, the carrying unit 300 is approaching the first press 10 to carry in the next material 3).

When the gripping of the finger part 410 is released, the second X slider 510, the second Y slider 520, and the second arm 530 are driven in the reverse order, and the material adsorbed on the second adsorption part 540 ( 3) is transferred to the second press 20 side.

When the material 3 is placed on the second press 20, the second Y slider 520 is driven and the material 3 is placed on the second press 20. Thereafter, when the adsorption of the second adsorption unit 540 is released, a second press process is performed on the other surface of the material 3.

In this way, the carry-out unit 500 transfers the material 3 in the form of a multi-stage slide, similar to the carry-in unit 300, so that the power required for the transfer process can be minimized.

As described above, in the present invention, the carry-in unit and the carry-out unit face each other with the material in the center and are driven individually, and the adsorption units included in the carry-in unit and the carry-out unit are independently driven, thereby minimizing the power required for the transfer process. In addition, since the material is reversed in place, the space occupied by the transfer device can be minimized.

In addition, the present invention can perform the transfer and reversal of the material more quickly and stably through a simple process in which the material is handed over in the middle of the material being transferred, and the both sides of the material are grabbed with the flexible finger joints of the reversing unit and immediately reversed. There is an advantage.

In the present invention, after the imported material is inverted and taken out to the second press, the reversing operation is omitted in a manner in which the reversing unit is not reversed, but a new material is transferred from the first press and continuously inverted. , There is an effect that the transfer process can proceed more efficiently.

On the other hand, the second arm 530 and the second adsorption unit 540 of the take-out unit 500 are inverted by the reversing unit 400 to horizontally transfer the laid material 3 to the second press 20. Although it is a structure, there is a case that the material 3 is rotated by 90° and put into the second press 20.

That is, when the press mold provided in the second press 20 is erected, press processing is impossible while the material 3 is laid down, so the material 3 must be rotated by 90° to be erected.

To this end, the second arm 530 and the second adsorption unit 540 of the carrying unit 500 are removed, and the rotation unit 600 is removed from the carrying unit 500 as shown in FIGS. 7 and 8. 2 It is mounted on the Y slider 520.

The rotation unit 600 is coupled to a moving bracket 610 so as to be slid in a horizontal direction along the extended section of the second Y slider 520, and the LM guide ( 620) is installed.

In addition, a screw 630 is installed in parallel with the LM guide 620, and the screw 630 is fixed to the moving bracket 610, and the screw 630 is inserted into the second pulley 631 and installed.

The second pulley 631 is fixed to the movable bracket 610 so that when the second pulley 631 is rotated while the second pulley 631 is fixed, the screw 630 is applied to the second Y slider 520 according to the rotation direction. It moves forward and backward in the direction orthogonal to.

Further, since the screw 630 is coupled to the LM guide 620, the LM guide 620 slides in a direction orthogonal to the second Y slider 520 due to the forward and backward movement of the screw 630. .

The rotational force of the second pulley 631 is supplied from the first motor 640, and the first motor 640 is mounted to be fixed to the moving bracket 610, and a first pulley 641 is installed on the shaft thereof. , The first pulley 641 is connected to the second pulley 631 by a belt to transmit rotational force.

In addition, a rotating plate 660 is installed at the tip of the LM guide 620 so as to be rotated by 90° in the upward direction, and the rotating plate 660 can be rotated by a rotating shaft 661, and the rotating shaft 661 The fourth pulley 662 is installed.

This fourth pulley 662 receives rotational force from the second motor 650, the second motor 650 is fixedly mounted to the moving bracket 610, and the shaft of the second motor 650 The third pulley 651 is installed and connected by the fourth pulley 662 and the belt 652 to receive rotational force.

The rotating plate 660 is rotatably coupled by a rotating shaft 661 at a lower part of the front end of the LM guide 620, and the rear part of the rotating plate 660 is mounted so as to rotate around the rotating shaft 661, thereby upward direction. When rotated by 90°, the front end portion of the LM guide 620 and the rear upper portion of the rotating plate 660 contact each other to maintain 90°.

Meanwhile, a bar-shaped connection member 670 is fixed and installed on the rotating plate 660 so as to be perpendicular to the horizontal direction, and suction portions 671 for adsorbing the material 3 are provided at both ends thereof.

The adsorption unit 671 is installed as a magnet, and attaches the metallic material 3 by magnetic force.

In the central portion of the connecting member 670, a long hole 672 is formed in its longitudinal direction, and a plurality of fixing holes 663 are formed in the rotating plate 660, so the long hole 672 and the fixing hole 663 It is possible to fix the connection member 670 with a pin or a bolt, and the position of the connection member 670 in the rotating plate 660 can be easily and accurately changed and fixed by the long hole 672 and the fixing hole 663. You will be able to.

That is, the position can be adjusted in the X-axis direction by a plurality of fixing holes 663, and the position can be adjusted in the Y-axis direction by the long hole 672, so that the reversed material can be accurately adsorbed by the reversing unit 400. In addition, it will be possible to put the material 3 into the second press 20 at the correct position.

Therefore, as shown in Fig. 8(a), the moving bracket 610 moves with the rotating plate 660 placed horizontally on the second Y slider 520 to transfer the material 3 inverted from the reversing unit 400 to the rotating plate. The suction port 671 is adsorbed from the lower side of the 660, and moves to the position of the second press 20. During the movement, the rotating plate is driven by the second motor 650 as shown in Fig. 8(b). (660) is rotated 90° upward and is erected.

Thereafter, as the LM guide 620 is elongated by the rotation of the screw 630, the rotating plate 660 advances and approaches the mold provided in the second press 20, and thus the front portion of the erected rotating plate 660 The material 3 adsorbed to the second press 20 is put in a standing state.

When the input of the material 3 to the second press 20 is completed, the LM guide 620 is compressed by the reverse rotation of the screw 630, so that the rotating plate 660 moves backward, and the rotating plate 660 is removed. 2 By rotating by reverse rotation of the motor 650, it returns to the horizontal state.

Eventually, since the second Y slider 520 is mounted by replacing the rotating unit 600, the material 3 can be erected and put into the second press 20, so that a separate rotating equipment is not required. 2 During the process of moving to the press (20), the material (3) is rotated by 90° to achieve a fast process.

9 to 11 are diagrams showing another embodiment of the reversing unit, and a work guide 720 is installed on the upper surface of the work plate 710 to guide the inverted material 3 to be placed in the correct position. The unit 500 is capable of adsorbing and carrying out the material 3 at an accurate position.
