Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] The present invention relates to a work chute device for transporting a plate material (product or clamp) separated from a plate material (base material) in a plate processing machine such as a punch press.

(Prior Art) A work chute device in a turret punch press will be described as an example of a plate material processing machine. In order to transport a plate material (product or scrap) after punching, a single work chute is provided near a punching portion. It is provided so as to be vertically swingable between a substantially horizontal position and an inclined position. Therefore, after the end of the predetermined punching, the plate (product or scrap) separated from the plate (base material) is positioned on the work chute. By swinging the work chute downward from a substantially horizontal position to an inclined position, the plate (product or scrap) can be transported to a predetermined position via the work chute.

(Problems to be Solved by the Invention) However, in the work chute of the plate material processing machine as described above, since only a single work chute is provided on the table, the size of the work chute is limited to the plate material (product or product). In some cases, the size of the scrap is not appropriate. In other words, when the plate (product or scrap) is considerably larger than the work chute, the work (chute) is tilted downward and the plate (product or scrap) is conveyed. There is a problem that the plate material (base material) is damaged due to falling. When the plate (product or scrap) is larger than the work chute, there is a problem that the plate (product or scrap) is not properly transported even if the work chute is swung downward.

Therefore, a configuration is known in which a plurality of work chutes are provided adjacent to each other and each work chute is lowered by a cylinder provided corresponding to each work chute. In this case, the load of each work chute is different. At this time, there is a problem that it is difficult to integrally lower the work chutes in a synchronized manner without generating a step.

55 is provided adjacent to the front and rear, and the plurality of first, second,
By selecting the third work chutes 51, 53, and 55 so as to be vertically swingable between a substantially horizontal position and an inclined position, the first work chutes 51, 53, and 55 can be moved in the first direction according to the size of the plate material (product or scrap) W. An appropriate number of predetermined work chutes can be selected from the second and third work chutes 51, 53, and 55 to swing downward. Therefore, when the appropriate number of predetermined work chutes are swung downward, it is relatively less likely that the plate material (base material) W is drastically dropped and damaged. The plate material (product or scrap) W is too large for the work chute,
It is relatively less likely that the plate material (product or scrap) W will not be transported.

Note that the present invention is not limited to the description of the above-described embodiment. For example, when the auxiliary punching device 45 punches a lower left portion of a plate (product or scrap) W, the movable table
The present invention can be embodied in various other modes by making an appropriate change such as extending the rear portion 39 further.

[Effects of the Invention] As can be understood from the above description of the embodiment, in short, the present invention provides a plurality of work chutes provided adjacent to each other on a table supporting a plate in a plate processing machine, and supporting the plate. From the horizontal position to an inclined position in which one end is lowered, and the plurality of work chutes are capable of engaging and disengaging the one end of the work chute in the table in a horizontal state and capable of releasing the engagement and holding. Is provided corresponding to each work chute, and an elevating member having a plurality of support members for supporting each work chute from below is provided by extending in the arrangement direction of each work chute. An up-and-down actuator for vertically moving the elevating member is provided.

As is apparent from the above configuration, in the present invention, one end of each work chute can be engaged and held in a horizontal state and can be released in correspondence with the plurality of work chutes provided adjacent to each other on the table. The lifting member provided with a plurality of support members for supporting each work chute from below is extended in the direction in which the work chutes are arranged, and further moves the lifting member up and down. Up and down actuators are provided.

Therefore, according to the present invention, when each work chute is horizontally supported from below by each support member provided on the elevating member, the elevating member is released after releasing the engagement and holding of the appropriate engagement holding device. When the work chute descends, only the work chute which has released the engagement is swung downward and tilts.

That is, according to the present invention, when the elevating member descends,
Only the work chute from which the engagement and holding of the engagement holding device is released descends while being supported by the elevating member. Therefore, it is easy to select the number of work chutes to be inclined according to the size of the plate material to be carried out from the table, and simultaneously lower the plurality of work chutes integrally without causing a step or the like. In addition, a plurality of work chutes can be moved up and down at the same time by a common elevating member, and the configuration for simultaneously moving up and down a plurality of work chutes can be simplified.
