Abstract

PROBLEM TO BE SOLVED: To provide a new regular length string winding drum for winding a string only by a prescribed length for binding and temporarily binding in a wound state, and a winder using the drum. SOLUTION: The drum consists of a drum body 2 comprising a string engagement part 4 and a notch 5 for binding, a roll tape 6 to be drawn out as a binding tape T, a tape cutter 7 mounted on the top end side of the notch 5 for cutting the binding tape T, and a temporary attaching means 8 for temporarily attaching the binding tape with the adhesive surface facing upward. A prescribed length of the string is wound around the outer surface of the drum body by engaging the top end side of the string (h) with the string engagement part 4 and rotating the drum body a prescribed number of times. The binding tape is drawn out to cover the wound string Wh, and the string Wh on this condition is drawn out forward to be separated from the drum body. In this way, the binding tape surrounds the string Wh and binds the string.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for winding a string, such as a paper string, used for binding used newspaper or the like by a predetermined length used for binding, and temporarily binding the wound body. And a winding machine using the drum.

[0002]

2. Description of the Related Art Conventionally, newspapers that have been read in each household are usually collected and recycled by a used paper collection company in a state where they are tied together with a string different in material from the newspaper, such as a vinyl string for packing. It is used as a resource.

[0003] However, in order to use these old newspapers as recycled resources, foreign materials remain mixed in the recycled materials if vinyl strings (synthetic resin strings, hereinafter referred to as vinyl strings) are used together. So, each time the vinyl string was cut and removed, but this requires time and effort,
There was a problem that the disposal of the vinyl string had to be considered separately. Further, if the plastic cord is incinerated while being bound with a vinyl string without being used as a recycled resource, the vinyl string has a high calorific value and may damage the incinerator and generate harmful gas, which is not preferable. Further, when buried and disposed with being bound by a vinyl string, there is a problem that only the vinyl string remains in the natural environment.

[0004] Therefore, recently, in order to bind used newspapers, instead of using a string material such as a vinyl string which is different from the material of the newspaper, a paper cord which is twisted to a certain thickness has been used. It is becoming. Such paper cords are sold in a state of being wound from several meters to several tens of meters, and each household draws out, cuts, and uses it each time for the necessary length to bind used newspaper. are doing. For example, Japanese Patent Application Laid-Open No. 2000-7014 discloses such a paper cord as a recycled paper cord formed by twisting recycled paper made from recycled newspaper pulp or other recycled pulp to form a cord. Have been.

However, when the paper string is pulled out from the wound material by a length necessary for bundling and cut, it may be cut short by mistake or cut long by mistake. Is often wasted. Therefore,
From the experience, the length of a paper cord usually used to bind used newspaper is determined based on experience, and the length is determined, for example, to 2 m or 3 m. Temporarily tied in this state, several bundles are now available in the form of bags.

[0006] The above-mentioned paper string does not require much cutting, and the amount of used newspaper may be adjusted according to the length of the paper string and the paper string may be bound as it is.
When used as a recycled resource, it can be recycled together with old newspaper, and when it is incinerated or buried, there is no problem as in the case of binding with a conventional vinyl string.

However, the production of the above-described paper cord temporarily bound in a small wound state is performed by a person winding a predetermined length on a palm or the like, cutting it, and temporarily binding it. In addition to being troublesome, the size of the wound product varies, and mass production is not possible, so that there is a problem that it cannot keep up with demand. Attempts have been made to mechanize and fully automate these operations. However, multiple processes such as the supply, winding, temporary bundling, and cutting processes for paper-like materials such as paper strings can be performed in a short time. When doing repeatedly,
If there is a problem in any of the processes, it is necessary to stop all processes, set up again and start from the beginning,
At present, such a yield is high, and there has been a problem that productivity is not improved.

[0008]

According to the present invention, the above-mentioned conventional paper cord or the like is wound several to several tens of times and temporarily tied in that state to produce a product. Considering that it is difficult and it cannot be mass-produced by manual work, a constant length winding drum and a new winding using this drum that enable efficient winding and bundling. It is an object to provide a machine.

[0009]

SUMMARY OF THE INVENTION An object of the present invention, which has been made to solve the above-mentioned problems, is to provide a fixed length winding drum of the present invention which is a drum body tapered toward a front open end. A drum body having a string body locking portion for locking the front end side of the string body and a binding work notch formed rearward from the opening end; and a binding body provided inside the drum body for binding. A winding tape to be drawn out as a tape, a tape cutter provided at the tip side of the working notch for cutting the binding tape, and a tape between the cutter and the winding tape, the binding tape being attached to the adhesive surface side. A temporary attachment means for temporarily attaching the drum body in an upward state, wherein the outer periphery of the drum body is rotated by rotating the drum body a predetermined number of times by locking the leading end side of the cord body to the cord body locking portion of the drum body. Wind a predetermined length of the cord body on the surface, The binding tape is pulled out and put on the lace body, and in this state, the lace body is pulled out and detached from the drum body, so that the tying tape surrounds and binds the lace body and is cut by a tape cutter. It is characterized by having been done.

[0010] The present invention has been made in order to solve the above-mentioned problems. The winder of the present invention comprises the above-mentioned fixed length winding drum, and a motor with a brake for rotating the drum of the drum a predetermined number of times.

[0022]

The present invention has been described above. According to the fixed length winding drum of the present invention, a fixed length string can be wound and bound at a high speed. It is possible to mass-produce small rolls such as paper strings used for binding used paper. As a result, there is no need to use a string body made of a different material from newspaper, such as a conventional vinyl string for packing, and an effect is obtained in that old newspaper can be easily used as a recycled resource. Also, in the case of incineration disposal or landfill disposal, a special effect that the incinerator is not damaged and the natural environment is not destroyed can be obtained.

Further, according to the winding machine of the present invention, which incorporates the above-described fixed-length winding drum, the operation of producing a small wound body such as a paper string using the fixed-length winding drum is further improved. A special effect that it can be performed in a special manner is obtained.
