Description

[Detailed Description of the Invention] This invention relates to a conveying device for taking out scraps produced in, for example, press processing from below a press machine.

Conventionally, when edging a plate to be formed using a press machine, a belt conveyor was placed below the press machine, and the scraps were dropped onto the conveyor and taken out of the press machine.

However, in this conventional belt, when receiving scrap, the belt is easily damaged by the sharp edges of the scrap, the belt must be frequently repaired, and the period of use is limited.

This idea was created by focusing on the above problem,
The purpose is to provide a conveying device that is not affected by scrap and is compact overall.

Examples will be described below based on the drawings.

In FIGS. 1 to 3, 1 is a conveying device disposed below a press machine (not shown), 2 is a fixed pedestal, and includes a plate-shaped side pedestal 2a extending along the scrap conveyance direction and a central pedestal. It consists of a stand 2b.

The fixed pedestal 2 is attached to a base 4 by a support 3.

5 is a plate-shaped movable pedestal placed between the fixed pedestals 2a and 2b.

Reference numeral 6 is an idle rod that is inserted into and supported in a hole formed in the support column 3 in a position parallel to the fixed pedestal 2, and is capable of sliding along the support column 3.

7 is a support member fixed to the guide rod 6; 8 is a base 4;
The air cylinder is pivotally supported in the elongated hole portion 4a by a bracket and a bottle, and is designed to move forward and backward in conjunction with the operation of the press machine.

Reference numeral 9 denotes a rotary lever, the pivot point 9a of which is supported by the support member 7 by a shaft 10, while the upper lever 9b is attached to the movable plate 5 by a shaft 11, so that the movable plate 5 is supported by the guide rod 6. are doing.

Further, the lower levers 9C of each rotating lever 9 are connected by a bar 12.

The piston rod end 8a of the air cylinder 8 is attached to a lower lever 9d of one of the rotary levers 9.

The support members 7 and 7 that supported both sides of the rotary lever 9 include a stopper member 13a that restricts the rotation of the rotary lever;
13b.

As shown in FIG. 3, the movable pedestal 5 has a minimum height that is lower than the height of the fixed pedestal 2 as the rotary lever 9 rotates, and a maximum height that is lower than the height of the fixed pedestal 2. The lower lever 9d of the rotating lever 9 is longer than the upper lever 9b.

In this embodiment, as described above, when the air cylinder 8 is extended, the rotating lever 9 rotates in the direction of the arrow A until the piston rod end 8a abuts the stopper member 13a.

At this time, the movable pedestal 5 rises above the fixed pedestal 2.

As the air cylinder 8 continues to perform the expansion operation,
The movable pedestal 5 moves in the direction of arrow B together with the guide rod 6 while being raised.

Next, when the air cylinder 8 is compressed, the rotary lever 9
rotates in the direction of arrow C until the piston rod end 8a abuts against the stopper member 13b.

Therefore, the movable pedestal 5 descends from the raised position to below the fixed pedestal 2.

As the air cylinder 8 continues to contract,
The movable cradle 5 moves in the direction of the arrow along with the guide rod 6 while being lowered and returns to its original position.

According to this device, by repeating the above operation, the rotary plate 5 lifts the press scrap that has fallen onto the fixed pedestal 2 and moves it to the take-out side, and the scrap is transferred to the front part of the fixed pedestal 2. It can be transferred and transported outside the press machine.

Further, this device is relatively lightweight and easy to carry, can be installed at any location by attaching and detaching the air hose of the air cylinder 8 to the air supply source, and has the advantage of being easy to use by simply switching the valve.

In addition, in the above embodiment, two movable pedestals are arranged, but two
One movable pedestal may be arranged between two fixed pedestals, or the rotating lever may be directly attached to the guide rod with a pin or the like without using a support member.

Furthermore, the stopper member may also be formed into a pin shape and attached to the guide rod.

As is clear from the above, this invention not only transports press scraps, etc. reliably, but also eliminates the risk of being damaged by press scraps, unlike belt conveyors.
It requires almost no management.

Furthermore, the overall structure of the device is low, and it can be sufficiently applied to small-sized press machines.

Although the embodiment has been described as a device for taking out press scrap, it can also be used as a conveying device for lightweight articles.
