In this way, without the traditional separate drive source,
The automatic workpiece feed device uses the mold slide drive source of the press itself to automatically send the workpiece to the processing position. The pusher mechanism pushes the workpieces one by one to the supply position, ie, position b, and then the workpiece gripping member advances to position and place the workpiece in the processing position, ie, position d, and then retreats to return to the supply position. has been done. However, this conventional workpiece automatic feeding device can only reciprocate the workpiece gripping member in the lateral direction of the press machine for each press process, and is The disadvantage of this method is that the worker must take out the formed workpiece from the processing position each time the press processing process is completed, resulting in poor work efficiency, safety issues, and high labor costs. It was hot. Therefore, in order to solve various problems such as work inefficiency, danger, and labor costs in automatic feeding of workpieces, there is a need for a device that automatically takes out workpieces from the processing position. However, the number of workpiece gripping members provided on the slide bar is increased, and the workpiece gripping members are fed and raised and lowered at the supply position, processing position, and take-out position in the workpiece feeding direction to grip the workpiece. Alternatively, in order to release the workpiece, a mechanism must be provided in which the workpiece gripping members do not interfere with the slide of the press.

The present invention has been made in view of the above-mentioned drawbacks, and it is possible to automatically feed a workpiece to a supply position without any human intervention, without providing a dedicated and separate drive source, and from the supply position to a processing position. We have developed an automatic feeder for workpieces that improves the efficiency of pressing workpieces, performs the work safely, and saves labor by being able to feed the workpieces and transport them from the processing position to the take-out position. This is what we are trying to provide.

FIG. 2 is a perspective view showing an embodiment of the automatic feeding device of the present invention applied to a press working device. A number of workpiece gripping members 23 corresponding to the number of lower molds 15 are arranged in parallel, that is, in a lateral direction. When the slide 16 on which the upper mold 17 of the press machine 11 is mounted starts to descend by the motor drive source (not shown) of the press machine 11 in order to press the workpiece 19, the motor drive source simultaneously Rotating wheel 2
0, the third via link member 28 and lever 27
As shown in the figure, the cam shaft 26 is rotated in forward and reverse directions, and the pusher 40 in the pusher mechanism 22 is reciprocated in the arrangement direction of the lower mold 15 via the feed arm 36, as shown in FIG. The workpiece is pushed out from the workpiece mounting magazine, ie, position a, to the supply position b. The forward and reverse rotation of the camshaft 26 also causes the cross-feeding arm 49 to swing as shown in FIG. reciprocate in the direction of arrangement. As will be explained with reference to FIGS. 6 and 7, as the slider 16 of the press 11 descends, the striker 77 fixed to the slider 16 descends and strikes the striker holder 78, thereby causing the swing arm 70 swings and before the slide 16 reaches the workpiece 19, the holder 42, that is, the workpiece gripping member 23, is retreated in a direction perpendicular to the arrangement direction of the lower mold 15, and the workpiece gripping member 23 is moved back.
interference with the slide 16 is avoided, and press working by the slide 16 is enabled. Next, while the slide 16 of the press 11 is rising, the workpiece gripping member 23 is moved laterally as described above, and the lower die 15 is moved in the opposite direction to the arrow 81 in FIG. The pusher mechanism section 22 and the workpiece gripping member 23 have now returned to their original positions. One press process is completed above, and press forming is repeated in the same procedure thereafter. The processed and formed workpiece is sequentially moved to the lower mold 15 as shown by arrow 81.
and is pushed out to the take-out position in a direction perpendicular to . Thereafter, the processed workpiece is transported to the next processing position by a conveying means such as a belt conveyor (not shown) installed at this take-out position.

9, the tip of which is rotatably connected to the slider 50 with a pin 49a. The slider 50 holds a protrusion 51a of a slide guide 60 fixed to one side of the holder 42 so as to be able to reciprocate in the vertical direction. On the other hand, the horizontal feed arm 49
One end of a connecting link 52 is rotatably coupled to the base of the link 52, and the other end is rotatably coupled to the tip of an arm 53 fixed to the other end of the driven shaft 32. . Therefore, the camshaft 26 is
When rotated in the directions of arrows C 1 and C 2 in the figure, the driven shaft 3
2 rotates in the directions of arrows D 1 and D 2 , and the lateral feed arm 49 rotates in the directions of arrows D 1 and D 2 via arm 53 and connection link 52 .
It swings in the G 1 and G 2 directions, is rotated around the camshaft 26, and the slide bar 43 is guided by the V-grooved roller 42a and fed laterally. Here, since the slider guide 60 and the slider 50 are interposed at the joint between the cross-feeding arm 49 and the slide bar 43 to relieve the influence of the vertical movement of the cross-feeding arm 49, the rotation of the camshaft 26, that is, the cross-feeding arm 49
Due to the swinging movement of the slide bar 43, smooth lateral movement without vertical displacement of the slide bar 43 can be realized.

FIG. 6 is a side view showing a retraction mechanism for the workpiece gripping member, that is, a holder retraction mechanism in this embodiment, and FIG. 7 is a partially enlarged top view of the retraction mechanism in FIG. 6. The striker holder 78 is attached to the bracket 7
It is fixed to a slider 60 that slides via a bearing 68 about a support shaft 65 in the slider 9 . This slider 60 is pressed downward by a coil spring 66, and at the same time is constantly pressed upward by an air cylinder 84 shown in FIG.
0 is normally balanced and held at the upper limit position within bracket 79. Air cylinder 84 is press machine 1
This is provided so that the workpiece gripping member 23 can be moved to the retreat position even if the first slide 16 does not descend. For example, when it is desired to retract the workpiece gripping member 23 to the retracted position for inspection, repair, etc., the upward pressure on the slider 60 is released by opening the air relief valve (not shown) of the air cylinder 84. The gripping member 23 can be moved backward. The air relief valve also operates when the slider 60 descends due to the impact from the striker 77. The tip of the link 67 is fitted into a groove 71 formed on the side surface of the slider 60 via a roller 69, and is operatively connected to the slider 60.
