Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box for temporarily storing scraps such as iron plate scraps generated during cutting work and chips generated during cutting, a scrap discharging apparatus and a scrap discharging method using the box. is there.

[0002]

2. Description of the Related Art A large amount of scrap is produced after punching a part in punching or cutting of a press. If this scrap is a metallic material, it is collected by an iron scraps company and regenerated, so that it is collected at a scrap collection site provided in one corner of the factory. A scrap box for temporarily storing scrap is placed on each processing machine, and when the scrap box is full, the scrap box is transported to the scrap collection site, and the scrap inside is discharged to the scrap collection site.
A scrap box will be installed again at the scrap outlet of the processing machine.

Conventionally, a box 51 as shown in FIG. 8 has been used as a scrap box used for the above purpose. That is, the main body 2 having the casters 3 on the bottom surface is provided with the opening / closing side plates 4 which are pivotally attached to the lower side 5 and which can be engaged and disengaged with the engaging and disengaging pairs 53 on both sides of the upper side. It is a structure.

The scrap box 51 is arranged at the scrap discharge port of each processing machine so that the scrap discharged from the processing machine falls into the scrap box at a proper time, that is, at the time when the scrap is full or to some extent. The scrap box is lifted by a forklift truck to the scrap collection site, and the scrap box 51 is discharged at the discharge position.
The scrap is discharged by manually operating the lever 54 to open the open / close side plate 4 to discharge the scrap inside to the scrap collection site, then close the open / close side plate 4 and install it again under the scrap discharge port of the processing machine. I was working.

[0005]

According to the above-mentioned conventional method, the lever 54 of the scrap box is disposed at the scrap discharging position.
When manual operation is performed, a large frictional force acts on the engaging portion of the engagement / disengagement pair 53 due to the weight of the scrap inside, and a large force is required to operate the lever, and when the engagement / disengagement pair 53 is opened. Since the open / close side plate 4 is suddenly opened due to the weight of the scrap inside, there is a problem that the work is dangerous.

Further, since no workers are usually assigned to the scrap collection site, the operator of the forklift truck who has carried the scrap box must open the scrap box. Therefore, during work, the forklift truck is placed at the scrap discharge position, the driver descends from the forklift truck and operates the lever of the scrap box to open the opening / closing side plate, and then returns to the driver's seat to lift or tilt the fork of the forklift truck. You have to do the work of discharging the scrap in the scrap box. Usually, the scrap collection site usually has a bad footing, and when the scrap discharge position is high, the lever 54 of the scrap box must be operated with the fork raised, so that the user can get on and off the forklift truck or move the lever 54. There was a risk of accidentally falling or falling when performing the operation.
