Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bundling device capable of quickly and reliably bundling a to-be-bundled object made of a long object, and more particularly to a bundling device for bundling a long object in a spiral shape.
[0002]
[Background Art and Problems to be Solved by the Invention]
Conventionally, an object to be bound made of a long object is formed by binding a binding band at different positions in the longitudinal direction of the long object in order and welding them, and as a result, from the front end to the rear end of the long object. Bundling was performed by bundling and welding with a tie band at a predetermined pitch.
[0003]
However, in such a binding form, when the binding band is a resin band or string, it is necessary to weld and cut the binding band at each binding location, and welding and cutting per location The time required for welding, particularly the time required for welding and cooling thereof, is required for 5 to 6 seconds each. Therefore, for example, when a long object of about 3 m is bound at a pitch of about 100 mm, the total is considerably large. It took time to unite.
[0004]
By the way, in recent years, processing of industrial waste, for example, plastic waste such as plastic bottles generated in large quantities, has become a problem. Currently, after cutting (crushing) into chip pieces of a predetermined size, these are processed at high pressure. The present condition is that it is compressed into a long form and transported to a reprocessing plant or the like.
[0005]
In the case of these wastes, since the economic added value is low, if the binding time is taken in the same way as a normal product, the processing cost becomes expensive, and the binding is also accelerated. There is a need to reduce costs.
[0006]
The present invention has been made in view of such a situation, and an object of the present invention is to provide a bundling device capable of bundling a long object as a bundling object including the above waste quickly and inexpensively. And

When performed by a pressure cylinder, this is an embodiment that can be implemented inexpensively and safely due to the power medium.
[0011]
Further, in the above bundling device, the operation control of each actuator can be automatically performed by the control device during the bundling operation of the objects to be bound.
[0012]
