Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is capable of transporting packed bodies of compressed waste paper, etc.
The present invention also relates to a packaging wire cutting/removal device capable of cutting and removing the wire used to bind the package.

[Conventional technology]

After waste paper such as newspapers and magazines is collected, it is compressed into a rectangular parallelepiped of approximately 1 x 1 x 2 m, and the sides of the rectangular parallelepiped are bound with multiple wires to form compressed waste paper. This compressed waste paper is transported.

At a paper mill, it is crushed in a crusher, melted, and recycled. In order to supply the waste paper to the crusher, it is necessary to remove the wire from the compressed waste paper.

Conventionally, wire removal from compressed waste paper has been carried out manually by one worker. That is, one worker cuts the wire with a scissor-like cutting tool, and then pulls the wire out of the waste paper by hand.

However, such wire cutting and removal work by such workers is dangerous and hard work, and is also unfavorable from a sanitary standpoint since the working environment is poor.

A device that mechanically cuts and removes wire from compressed waste paper.

This method is proposed in JP-A No. 60-110633, ``Wire removal device for compressed waste paper'' and JP-A-60-110634, ``Wire cutting device for compressed waste paper, etc.''. The devices proposed in these publications are fixedly installed in a predetermined position, and are configured to cut and remove wires from the sides of waste paper conveyed by a conveyor.

In addition, another method has been proposed in Japanese Patent Application Laid-Open No. 63-307033 entitled "Packing Wire Cutting and Removal Apparatus". The device proposed in this publication is a self-propelled trolley equipped with an elevating platform.

A first claw and a second claw are provided on the lifting platform so that it can be approached and separated from the left and right, and the package is sandwiched between the third claw and the second claw,
It is designed to cut the wire by lifting it up.

[Problem to be solved by the invention]

However, all such conventional devices have had problems.

That is, in the former device, since the device is fixed at a predetermined position, there is a problem in that in order to cut and remove the wire of the package with the device, the package must be transported to that position.

Furthermore, since the latter device is equipped with nine carts, it can move to a desired position and cut the wire of the package, but it does not have the function of transporting the package.

There is still a problem in that the package must be transported to the cutting position.

The present invention has been made in view of these problems, and it is an object of the present invention to provide an apparatus having a function of transporting a package and a function of cutting and removing the wire of the package.

(Means for solving problems) The present invention has been made to achieve such an object.

A self-propelled trolley, a pair of bail clamps attached to the trolley and holding the package across the sides, and a pair of bail clamps placed in a position to contact one side of the package held between the bail clamps. and a wire cutting device disposed at a position in contact with the other side of the package, wherein the wire grasping device moves with respect to the fixed claw and cuts the wire between the fixed claw and the fixed claw. A packing wire characterized in that the wire cutting device has a movable claw that grips the wire, and the wire cutting device has a fixed blade and a movable blade that moves relative to the fixed blade and cooperates with the fixed blade to cut the wire. This paper focuses on cutting and removing equipment.

[Effect]

In the apparatus configured as described above, the sides of the package can be held between the pair of bail clamps, and the package can be transported to any desired position by running the trolley in this state. Moreover, when the wire gripping device and the wire cutting device are activated and the movable claws and movable blades are moved with the package sandwiched between the bail clamps, the wire cutting device cuts the wire, and the wire gripping device cuts the wire. Then, by opening the bail clamp, the holding of the package is released, and then by raising or retracting the wire gripping device that grips the wire.

The wire can be pulled out from the package.
