くなるという問題点があつた。 In this way, in the conventional workpiece storage device shown in FIGS. 1 to 3, all the workpieces W move upward at the same time, so that when the lifter 6 moves upward, the workpieces W from the previous process are the most If the work W is not carried into the lower receiving finger 4, the work W is not accommodated in a part of the work storage device, which is a so-called empty state. Therefore, for example, before the workpiece W processed in the previous process is carried to the lowest stage, the workpiece W is extracted to supply the workpiece to another line, and the workpiece W is not carried to the lowest stage. When there is no lifter 6
When the workpiece W is raised, there will be a portion where the workpiece W is not accommodated. Therefore, as shown in FIG. 4, in the state where the workpieces W are stored in multiple stages, there is no workpiece W at the location shown by the imaginary line, for example, and even if the lifter 6 is driven, this location will not move upward. This area will not get clogged just by moving. Therefore, when this location becomes the topmost position, the workpiece W no longer exists at this location, so it is necessary to stop the hanger or hook (not shown) for transporting the workpiece W to the next process. There is. As described above, the conventional work storage device has a problem in that there is a waiting time for hangers and hooks, which reduces production efficiency.

動するようにしても良い。 As shown in FIG. 5, when the lifter 6 is moved upward with the feed fingers 9 closed, the work W supported by the receiving fingers 4 corresponding to each feed finger 9 rises by one step. Since it will move, all the works W will move upward at the same time. For this reason, the work W
If there is a portion that is not supported by the receiving finger, that portion will also move upward by one step, making it impossible to pack the workpiece W into that portion. Therefore, only the feed finger 9 corresponding to the receiving finger 4 that does not support the workpiece W and the feeder finger 9 located above this are opened to avoid contact with the workpiece W when the lifter 6 is raised, and to support the workpiece W. The lifter 6 is moved by keeping the feed finger 9 located below the feed finger 9 that corresponds to the receiving finger 4 that is not in the closed state.
A hydraulic cylinder 16 serving as an opening/closing means for moving the work upward when the workpiece is raised is attached by a pin 18 to a bracket 17 fixed to the connecting bar 8, and a rod 19 of the hydraulic cylinder 16 is connected to the feed finger 9. ing. The rod 19 and the feed finger 9 are connected to the fluid pressure cylinder 1
A connecting pin 20 attached to the rod 19 engages with an arc-shaped groove 21 centered on the pin 13 so that the feed finger 9 can rotate independently of the operation of the feed finger 6. Further, when the feed finger 9 is opened by operating the fluid pressure cylinder 16, the fluid pressure cylinder 16 opens the pin 18.
Tilt around the center. In addition, 22 is a notch for engaging the flange F etc. formed on the workpiece W. In addition, a fluid pressure cylinder 16 is used as the opening/closing means.
However, the rod 19 may be operated by a solenoid or the like.

クWcが上昇して来る。 Next, the operation of the present invention will be explained with reference to FIGS. 10 to 12. The state of upward movement of the workpiece W when all the receiving fingers 4 contain the workpiece W will be explained with reference to FIG. 10, which shows three works Wa to Wc. When the connecting bar 8 of the lifter 6 is raised with the workpieces Wa to Wc supported by the fingers 4, the feed finger 9 moves the workpieces Wa to Wc.
After contacting the lower surface of the workpieces 1 and 2, each of the workpieces Wa to Wb is subsequently raised by the lifting of the lifter 6, and the receiving finger 4 on the upper side is lifted up as shown in FIG. 10B. When the lifter 6 rises to its highest limit, the receiving finger 4 is released by the workpieces Wa to Wc, and the receiving finger 4 becomes closed around the pin 11 due to its own weight, as shown in FIG. 10C. Next, by lowering the lifter 6, the workpiece W is supported as shown in FIG. 10D on the receiving finger 4 which was kicked up in the state shown in FIG. 10B. In this way, each of the workpieces Wa to Wc moves upward by one step. In Fig. 10, the workpiece Wa, which was initially located at the uppermost side in the figure, moves upwards, and the workpiece Wb rises to the position of the workpiece Wa, and the workpiece Wb
At the position, the workpiece Wc, which is one level lower than the workpiece Wb, rises.

た状態となる。 If the workpiece W does not exist at the position indicated by the imaginary line Wb in FIG. 11A, the feed finger 9 at the position corresponding to the position of the workpiece Wa and the position Wb where no workpiece exists is moved to the position shown in FIG. 11B. It is opened by actuating the hydraulic cylinder 16 as shown. If the lifter 6 is raised under this condition, the workpiece Wa will not be raised and only the workpiece Wc will be raised.
By rising to the position Wb, the workpiece storage device becomes clogged with workpieces W as shown in FIG. 11C.

い。 The opening/closing control of the feed fingers 9 is such that each receiving finger 4 is provided with a sensor that detects the presence or absence of a workpiece W, so that the upper side is given priority and the feed fingers of the upper stage are opened more than the stage where there is no workpiece W. I'll keep it. As a result, as shown in FIG. 12, in all situations such as sending from the state of FIG. 12 A to the state of FIG. 12 B, or from the state of FIG. 12 B to the state of FIG. 12 C, etc. can also be handled. However, in reality, when there is a part below where no work exists, as shown in FIG. 12C, it is preferable to fill this part with the work W.

Attachment, the receiving finger and the feeding finger are each configured to be vertically rotatable so as to open upon contact with the workpiece, and the feeding finger corresponding to the receiving finger that does not support the workpiece and the feeding finger above this. Since a cylinder that opens only the feed finger at the position is attached to each of the feed fingers, the workpiece storage device can be kept clogged with workpieces, and the workpieces can be reliably transported to the next process from the workpiece unloading section. This eliminates production delays due to workpiece waiting time. In addition, since the workpieces can be packed in the workpiece storage device, there is no need to pay attention to the timing of workpiece loading, and the workpieces can be freely supplied to other lines before being loaded, allowing the previous process and the next process This made it possible to fully accommodate the difference in working hours between the two companies.
