Description

Transfer machine

The present invention is to allow the finger of the transfer machine to operate the finger according to the size of the workpiece to prevent the workpiece from falling due to mechanical vibration, etc. when the workpiece is automatically transferred to the transfer machine.

A typical transfer die is to set several molds on the same BOLSTER of a transfer press to have the same height to gradually process the workpiece in several processes to form a finished product.

At this time, the workpiece was automatically transferred to each process by the transfer machine.

A conventional transfer machine for automatically transferring a workpiece to each mold of such a transfer die is installed on both left and right sides and one side of the transfer die to transfer the workpiece 2 to each mold 1 as shown in FIG. A body 3 and a feed bar 4 mounted on the body 3 to linearly reciprocate in a direction perpendicular to the moving direction of the body 3 to mount and remove the workpiece 2 to the mold 1; The two fingers 5 and 5 'are fixed to one end of the feed bar 4 at intervals at which the workpiece 2 can be inserted, and the workpiece between the fingers 5 and 5' 2) it is composed of support plates 6, 6 'attached to the lower surface of the fingers 5, 5'.

And the feed bar 4 stops when the contact switch 7 attached to the tip is brought into contact with the surface of the workpiece 2, i.e., at the position where the pedestal 6, 6 'holds the workpiece 2 thereon. Configured.

Reference numeral 8 is a guide rail for guiding the movement of the body (3).

The conventional transfer machine configured as described above is attached to the fingers 5 and 5 'by linearly moving the feed bar 4 toward the workpiece 2 such that the workpiece 2 is inserted between the fingers 5 and 5'. The supporting plates 6, 6 ′ are inserted between the upper surface of the mold 1 and the lower surface of the workpiece 2 to support the workpiece 2.

At the same time the feed bar 4 stops as the contact switch 7 contacts the surface of the workpiece 2 at that position.

When the feed bar 4 is reversed, the work piece 2 is moved together with the feed bar 4 while being placed on the support plates 6 and 6 ', and the feed bar 4 is made of the work piece 2. When the reverse stops at the position beyond the upper surface of the mold 1, the body 3 moves along the guide rail 8 to the next process.

However, the workpiece that is moved to the next process by the feed bar and the body in a state held by the pedestal between the two fingers as described above, a problem that frequently falls off the pedestal under the influence of mechanical vibration occurring in the field.

Therefore, the present invention is to be able to squeeze the workpiece with the two fingers attached to the tip of the feed bar in view of this point.

The structure of the present invention is a body 103 and a feed bar 104 to automatically transfer the workpiece 102, as shown in Figure 2, a guide rail 108 for guiding the movement of the body 103, and It can support two fingers 105 and 105 ', one end of which is fixed at regular intervals at the tip of the feed bar 104, and the workpiece 102 between the fingers 105 and 105'. Support plates 106, 106 'attached to the lower surfaces of the fingers 105, 105' and the pedestals 106, 106 'in a position where the pedestals 106, 106' support the workpiece 102. In the transfer machine consisting of a contact switch 107 attached to the tip of the feed bar 104 to contact the surface of the

The fingers 105 and 105 'are coupled to hinges 110 and 110' at the front end of the feed bar 104, and the hinges 110 and 110 'are coupled to the rotation axis of the finger 105, Double-acting pneumatic cylinders 112, 112 'with the tips of the piston rods 111, 111' coupled to the fingers 105, 105 'to vary the spacing therebetween (105') and And a bracket 113 mounted with the double acting pneumatic cylinders 112 and 112 ′ on the feed bar 104.

Reference numerals 109 and 109 'are finger 105 and 105' stop contacts, and 114 and 114 'are high pressure air pipes.

According to the present invention, the feed bar 104 is stopped at the position where the contact switch 107 contacts the surface of the workpiece 102 when the feed bar 104 is linearly moved toward the workpiece 102. ), (111 ') is crushed in the double-acting pneumatic cylinder (112, 112'), the two fingers 105, 105 'are arcuately moved to the hinge shaft 110, 110' The gap between the ends becomes narrower, and when the contact switches 109 and 109 'mounted on the fingers 105 and 105' come into contact with the surface of the workpiece 102, the finger 105 is positioned at the position. The movement of the piston rod is stopped so that, 105 'is fixed.

In this case, the fingers 105 and 105 'are double acting pneumatic cylinders 112 acting on the piston rods 111 and 111' while the pedestals 106 and 9106 'support the workpiece 102. The workpiece 102 is gripped by a force equal to the pneumatic pressure in, 112 '.

Thus, the workpiece 102 is prevented from falling off the pedestals 106 and 106 'by mechanical vibrations when the feed bar 104 and the body 103 are operated to be transferred to the next process.

As such, the present invention enables the finger of the transfer machine to hold the workpiece with a constant force, thereby preventing the workpiece from being removed from the finger by mechanical vibration, etc., when the workpiece is moved to the next process by operating the feed bar and the body. This has the effect of improving the productivity.
