Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an inter-press workpiece transfer device that transfers workpieces between a plurality of presses in which workpiece mounting tables have different heights.

[Conventional technology]

In the plastic working of thin plates, if processing is difficult with a single press operation, multiple presses are used, but usually the installation height of the workpiece is increased from the bottom of the press, i.e.
The height of the lower mold is adjusted, the installation height of the workpiece is held constant, and the workpiece is transported between presses by a transporting means that moves up and down by a certain height and also moves laterally. was.

[Problem that the invention seeks to solve]

However, the installation height of the work from the bottom of the press varies depending on the capacity of the press or the manufacturer, so in order to adjust the installation height of the work, it is necessary to change the height of the base surface of each press. It required a lot of effort.

Furthermore, when changing the manufacturing method and rearranging the presses, it is necessary to adjust the installation height of the workpieces on each press again so that they are on the same horizontal plane, which requires extremely labor-intensive work. There was a problem.

The present invention was developed in view of these circumstances, and is a press that can freely transport the workpiece to be processed from the first press to the second press even if the installation heights of the presses are different. The purpose is to provide a temporary workpiece transfer device.

[Means to solve problems]

In the inter-press workpiece transfer device according to the present invention, which achieves the above object, the first and second workpiece holding means for holding the workpiece to be pressed are arranged at an interval that is half the distance between the first and second presses. a horizontal support member attached to both sides; a lateral transport means for moving the horizontal support member in a horizontal lateral direction;
A vertical conveying means for vertically moving the horizontal conveying means together with a horizontal support member, and a vertical conveying means disposed at an intermediate portion between the first and second presses, on which the workpiece to be conveyed by the workpiece holding means is temporarily placed. and a mounting table that moves up and down a predetermined length in accordance with the height of the worktable of an adjacent press, and the first workpiece holding means grips the workpiece from the workpiece installation part of the first press, The above i3 adjusted to the work installation height of the second press! After placing it on the equipment, the height of the mounting table is adjusted to the workpiece installation height of the first mold, the workpiece is gripped by the second gripping means, and the workpiece is conveyed to the workpiece installation section of the second press. It is configured in such a way.

Here, the first and second workpiece holding means may be a suction pad that uses vacuum force to attract objects in response to a predetermined signal, an electromagnet, or a device that physically grips the workpiece with an arm.

Further, one of the first and second presses is a conveying device such as a belt conveyor, and the workpiece is placed at a predetermined position.
This also includes those that can have 12 locations.

[Effect]

In the inter-press work transfer device according to the present invention, work holding means are provided at predetermined intervals on both sides of a horizontal support member.

Therefore, by first moving the horizontal support member horizontally and laterally and vertically, the first workpiece holding means captures and conveys the workpiece from the workpiece installation section of the first press.

In this case, by adjusting the height of the storage stand to the height of the workpiece installation part of the first press, it is possible to prevent the second workpiece holding means from colliding with the workpiece stand (and to lower it down). In this state where the workpiece on the mounting table can be caught by the second workpiece holding means, the workpiece caught by the first workpiece holding means is moved upward and laterally through the horizontal support member. ,'R At the same time, the height of the workpiece is adjusted to the height of the workpiece of the second press.By operating the first workpiece holding means, the workpiece is moved onto the workpiece stand. In this case, if the second workpiece holding means has caught the workpiece, it will be placed on the workpiece installation section of the second press.In this state, the horizontal support member is raised and moved laterally. Then, the first and second presses are moved back a distance necessary for operation, and the first and second press operations are completed.

Since the above process is repeated to perform press work, even if there is a slight difference in the height of the workpiece mounting tables of the first and second presses, the first and second workpieces can be moved by raising and lowering the mounting tables. The gripping means can be operated simultaneously to catch and release the workpiece.
