Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device for materials used in press machines. This conveying device is a device that is disposed between presses and feeds a blank product processed by one press to the other press via an intermediate stand (idle stage).

Conventionally, a material conveyance device used in a press machine has a moving body that is guided by the machine body and can reciprocate in the direction of conveying the material, and the moving body is equipped with a feed bar that is guided so as to be able to move up and down. The bar is provided with a holding device that holds and conveys the material, and the movable body and the feed bar are driven by separate drive devices. Therefore, there were drawbacks such as a complicated structure and a complicated control system because both drive devices were controlled and moved at the same time.

The object of the present invention is to eliminate these drawbacks, to drive the reciprocating motion of the moving body and the vertical motion of the feed bar with a single drive device,
Another object of the present invention is to provide a conveying device for materials, etc. whose drive is extremely simple to control and which is easy to handle. Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the conveying device (11) is arranged between the first press (2) and the second press (3). At both left and right ends of the body of the conveying device (1) The timing boot 1) (4) is rotatably provided. An NC motor (5) is fixed to the fuselage, and a timing pulley (61) is fixed to its output shaft.
) is applied to the timing belt (force is applied to the timing belt) and tensioned by an idle pulley (8) rotatably provided on the fuselage.

Timing belt (7) timing boo January 4) (4
) is reciprocated in the conveying direction of the material etc. by controlling the -NC motor (5) to rotate in forward and reverse directions.

Two guide shafts (9) are fixedly installed on the machine body in the direction of conveyance of materials and the like. The moving body (1) is guided by the guide shaft (9).
0) is provided so as to be able to freely reciprocate. Stoppers (141) for regulating the reciprocating range of the moving body (00) are provided at both left and right ends of the body.A feed bar 1121 is guided to the moving body (10) by its guide rod (01) so as to be freely raised and lowered. There is. At both ends of the feed bar (12),
Holding device that can be adsorbed and released when transporting materials (
131 (131 is fixed. In the embodiment, the holding device (13) consists of a vacuum cup, a bar that fixes it, and piping (131) for supplying and discharging vacuum air to and from the vacuum cup.
(not shown).

3 and 4, the moving body (10) and the timing belt (7), and the moving body (10) and the feed bar (
12) shows details of the connecting part.

A crankshaft (19) is rotatably provided on the moving body (10). One end of a connecting rod 071 is pivotally attached to the eccentric portion 0 mark of the crankshaft (151. The other end of the connecting rod 07) is connected to the feed bar (12) by pin Oat.The crankshaft (151
The outer periphery around which the timing belt (7) is wound is provided with a step that matches the step of the timing belt (7) and serves as a timing pulley. ! A brake disc (191) is fixedly attached to the crankshaft (151).
The brake shoe t:2n+ is energized to constantly apply braking force to the crankshaft (151).The movable body (10) is rotatably provided with a roller (22 (2'Z), The timing belt (7) wrapped around the
).

Next, we will discuss the effect. In Figures 1, 3, and 5, the slides of the first and second presses +2H3+ are lowered and the moving body (10) of the conveying device (1) is at the intermediate point shown in Figure 1 during processing. It's stopped. Press (2) (3)
When the processing is finished, the NC motor (5) is activated and the timing belt (7) is activated via the timing belt (7).
It reciprocates in the feed direction. At this time, the crankshaft 09 of the moving body (1o) does not rotate because braking force is applied by the brake disc 09, brake shoe (2o), and spring Cυ, and therefore the moving body 001 is guided by the guide shaft (9). and moves together with the timing belt (7). For example, moving further to the right from the position shown in FIG.
) moves, the crankshaft 05) rotates against the braking force. When the crankshaft (19) rotates by an angle θ, the NC motor (5) starts to reverse rotation, but while the crankshaft (151) rotates by an angle θ, the eccentric part θB and the connecting rod 071
and the feed bar (121) via the pin (18) descends with a required partial stroke length, rises again and stops.

When the feed bar (121) is lowered, the holding device (13I
Vacuum air is supplied and discharged to adsorb or release materials, etc. When the NC motor (5) starts rotating in reverse, the crankshaft (
151 does not rotate due to the braking force, the movable body (10) moves to the opposite side of the body along with the timing belt (force).

Perform the same operation on the opposite side and tighten the crankshaft (15
) rotates by an angle θ, the feed bar (12) moves up and down, and the NC motor (5) starts rotating forward.

Now, the mode of movement will be explained using the holding device shown in Fig. 1 (+31 (+31 is represented by P and Q as shown in Fig. 5). When the press +21 f3+ finishes machining, its slide rises and starts the next machining. Until P and Q are a, b, c...g
P moves to the mold (23) of the press (2), picks up the semi-finished product from there, and transfers it to the intermediate cradle (idle stage) (transported to the second force and returned to the original position. Meanwhile,
The machine moves to the pedestal (2), picks up the semi-finished product from the previous process placed on a part of it, transports it to the mold (25) of the press (3), and returns to its original position. These movements are N
The C motor (5) is given the required forward/reverse rotation and stop control.

As is clear from the above description, according to the present invention, (I
The INC motor can be controlled to provide reciprocating motion of the moving body and vertical motion of the feed bar. (2) The control system can be simplified by controlling the supply and discharge of parqueam air from the holding device in synchronization with this movement. (3) The overall structure is simple. Therefore, handling is facilitated. The practical effects and advantages are extremely large.
