Abstract

PURPOSE:To shorten a work tact by constituting the titled device so that a product which has been cut by the lower edge by an ascent of the lower metallic die is projected into the upper metallic die, and the product is taken out by a suction head from its through-hole. CONSTITUTION:When an air cylinder 13 ascends, the lower edge 9 goes into the upper metallic die 8, and a product 10 which has been cut is pushed up into a through-hole of the upper metallic die. Subsequently, a robot 12 descends, a suction head 11 sucks the product, the lower metallic die 7 descends, and also, the robot 12 places the project in a prescribed position and shifted to the next operation. Since the product is taken out upward, a stroke of the lower metallic die 7 is minimized, the up-and-down operation of the metallic die and taking-out of the product are overlapped, and a tact of the process can be shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cutting device for cutting a product portion from a hoop material and removing the product.

Conventional technology In recent years, due to automation in factories, there has been an increase in the number of cases in which presses are directly connected to assembly lines.In order to pursue production efficiency, the cutting equipment in these machines is capable of handling everything from cutting the hoop material to taking it out. There is a need to shorten the takt time for a series of operations.

An example of the conventional cutting device mentioned above will be described below with reference to the drawings.

FIG. 3 shows the configuration of a conventional cutting device. In Fig. 3, 1 is the lower mold, 2 is the upper mold, and 3 is the upper mold 2.
It is an air cylinder that lowers the

4 is a cut product, 6 is a suction head for layering the product 4, and 6 is a robot for mounting and moving the suction head 6.

The operation of the cutting device configured as above will be described below.

The upper mold 2 is lowered by an air cylinder 3, the product is cut, and then raised. The arm of the robot 6 is inserted between the upper mold 2 and the lower mold 1, and the suction head 6 attached to the tip is used to
The cut product 4 on the lower mold 1 is sucked and taken out.

Problems to be Solved by the Invention However, with the above configuration, the robot inserts the tip into the mold, so the vertical stroke of the mold cannot be made small, and the vertical movement of the mold and the robot movement overlap. Not only that, but the work takt time is long.

In view of the above-mentioned problems, the present invention provides a cutting device that minimizes the vertical stroke of the mold and overlaps the vertical movement of the mold with the take-out operation of the robot, thereby shortening the work tact.

Means for Solving the Problems In order to solve the above-mentioned problems, the cutting device of the present invention includes an upper mold having a through hole through which the cut product can pass, a lower mold, and a cutter that has a hole in the upper mold during cutting. The device is equipped with a lower blade that protrudes from the upper mold, a suction head that can take out the cut product through the through hole of the upper mold, and a robot that attaches and moves the suction head.

Effect: Due to the above-described configuration, the present invention does not require the tip of the robot to be inserted between the molds, so the vertical stroke of the mold is minimized, and the product can be taken out with the molds together for cutting. The vertical movement of the mold and the take-out movement of the robot can be overlapped, and as a result, the work tact can be shortened.

EXAMPLE Hereinafter, a cutting device according to an example of the present invention will be described with reference to the drawings.

FIG. 1 shows the configuration of a cutting device according to the present invention. In Figure 1, 7 is the lower mold, 8 is the upper mold, 9 is the lower blade, 1
o is a product to be cut, 11 is a suction head, 12 is a robot, and 13 is an air cylinder.

The operation of the cutting device configured as described above will be described below with reference to FIGS. 1 and 2.

First, FIG. 2 shows a state in which the air cylinder 13 is raised to cut the product 10 in the cutting section of FIG. 1. In this state, the lower blade 9 enters into the stopper die, and the cut product is pushed up through the stopper die 80. In this state, the robot 12 descends, and the suction head 11
Take out the cut product. After that, the lower mold 7 descends,
The mouth bot 12 places the suctioned product in a predetermined position by performing the following operation.

As described above, according to this embodiment, by providing a through hole in the cutting part of the upper mold, the robot can pick up the cut product with the suction head through the through hole. With the minimum vertical stroke, it is possible to have a wide overlap between the vertical movement of the mold and the robot's take-out operation, making it possible to shorten the takt time of the series of processes from cutting to take-out.

Effects of the Invention As described above, the present invention comprises an upper mold having a through hole through which a cut product can pass, a lower mold, a lower blade that protrudes into the upper mold during cutting, and a cut product that can pass through the cut product. Moreover, by providing a suction head that is taken out from the through hole of the mold and a robot that moves the suction head, it is possible to minimize the stroke of the mold and to overlap the movements of the mold and the robot. , it is possible to shorten the takt time for a series of operations from cutting the product to taking it out.
