By the way, in the above-mentioned conventional product accumulating apparatus for shearing which is a combination of a belt conveyor and an accumulating trolley, the size of the product on which the products can be aligned and accumulated on the accumulating trolley is at least 200 mm mm or more. is necessary. Therefore, in particular, in particular, products having a size of 100 mm square or less are aligned and collected while the operator picks up the products after the completion of the shearing operation in a fluttering state at the rear of the belt conveyor.

[0004] The reason for this is that the upper blade of the shearing machine has a shear angle of 1 to 3 with respect to the lower blade, and is mounted diagonally rather than parallel. For this reason, a gap margin (the amount of engagement between the upper and lower blades) is required, and the lower belt conveyor is usually provided with a drop of about 100 mm so as not to contact the lower blade mounting table surface of the shearing machine.

[0005] Therefore, when shearing small plate materials having a small shearing dimension, the product jumps up and does not drop to a fixed position on the belt conveyor, so that there is a problem that the product cannot be collected on the stacking cart with good alignment.

[0006] Various devices such as a magnet sheet support and a pneumatic support are known as well as a device for securely pressing a workpiece against a back gauge at the time of shearing. The function cannot be exhibited at the time of shearing.

An object of the present invention is to provide a shearing machine in which products sheared by a shearing machine, particularly small plate products, are accumulated in a horizontal state in a well-aligned manner and can be automatically loaded and unloaded in the next step. It is to provide a product integration device.

A drive pulley 23 is connected to an output shaft of the drive motor 21. A driven pulley 25 is provided in the lower frame 5, and an eccentric shaft 27 is mounted on the driven pulley 25. This eccentric shaft 27
Is connected to a lower end of a connecting rod 29, and an upper end of the connecting rod 29 is connected to a shaft 31 attached to the stay member 17. A belt 33 is wound around the driving pulley 21 and the driven pulley 25.

With the above configuration, when the drive motor 21 is driven, the drive pulley 23, the belt 33, the driven pulley 2
The eccentric shaft 27 is rotated via 5. The rotation of the eccentric shaft 27 causes the ram 15 to move up and down via the connecting rod 29, the shaft 31 and the stay member 17.

At the front of the upper frame 13, a plate holding device 35 is provided. When the work carried in on the work table 9 is placed and fixed and subjected to shearing, the work is held by the plate holding device 35. It is pressed and fixed from above.

Therefore, the work W is stored in the work table 9
The lower blade 11 and the upper blade 19 cooperate with each other by moving the ram 15 up and down in a state where the ram 15 is carried in and fixed at a desired position while the work is pressed and fixed by the plate holding device 35. Shearing will be performed.

One end of a work shooter 37 is attached to the fixed frame 7 in the lower frame 5, and is provided in a state inclined downward and to the right in FIG. A stacking shooter 39 is provided behind the work shooter 37 (to the right in FIG. 1).

More specifically, referring to FIG. 2 and FIG. 3, as the upright shooter 39, a V-shaped shooter 41 can be pivotally mounted on the lower frame 5 with a hinge pin 43 as a fulcrum. It is pivoted downward. For example, a cylinder 47 as a vibrator is attached to the lower frame 5 with a pin 45, and a piston rod 49 attached to the cylinder 47 is attached.
