Abstract

<P>PROBLEM TO BE SOLVED: To provide a shredder for a fastening band, which shredder has no complicated mechanism, and can be produced at a low cost, and is compact, and can be easily controlled, and can be easily moved to any place, and can be easily operated by any one. <P>SOLUTION: An electric power source is switched-on when a sensor arranged between a pair of fastening band drawing-in rollers has detected the charge of the fastening band. Then, the fastening band is drawn-in by driving the rollers by transmitting the turning torque into the perpendicular direction from a bevel gear fixed to the output shaft of a motor. Rotary blades are fixed to a rotary blade supporting shaft arranged on the other side of the bevel gear fixed to the output shaft of the motor, and a fixed blade is fixed to the lower portion of a bearing supporting plate for supporting both ends of the rollers. The fastening band is shredded by being cut-off between the rotary blades turning at a high speed by the rotation of the motor and the fixed blade. As a result, the shredder for the fastening band having a structure capable of processing a plurality of fastening bands at the same time can be easily formed only by increasing the rollers and the fixed blade without increasing the motor and the rotary blades and without enlarging its compact size. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a used binding band shredder such as a plastic band and a polypropylene band.

Because of its strength, the binding band after unpacking cannot be folded or grouped together. Even if it is shredded, it is inefficient when using scissors or push-cuts, and the processing time is enormous. It will hang on. Therefore, various devices for finely cutting have been devised.
1. Japanese Patent Laid-Open No. 2001-353691 discloses “Plastic Band Shredder and Roll with Blade for the Machine”, but there is a problem in using an expensive spiral plane cutter.
2. Japanese Patent Application Laid-Open No. 10-94994 discloses “Plastic Band Shredding Device”, which cuts one binding band and widens the interval between feeding rollers by a sensor when the end portion is clogged. In addition, there is a problem in that air is ejected to eliminate clogging, and there is a problem that the mechanism becomes complicated and the manufacturing cost increases.
3. Japanese Patent Application Laid-Open No. 7-277313 discloses a “binding band unwinding device”. Before unpacking, a part of the device is set on a part of the binding band, and the binding band is melted and cut. It is characterized in that clogging is prevented by chopping endlessly after the end portion is welded in the device at the beginning of the next binding band, and then chopped endlessly. There is a problem that a waiting time is generated during welding, the complexity of the apparatus itself is increased, and the manufacturing cost is increased.
4). Japanese Patent Application Laid-Open No. 9-24917 discloses a “binding band removing device”, but the device itself detects the band while moving along the side of the package, and the hook part is hooked and cut by the detected band. The band is cut inside the apparatus while drawing one end of the band, and is a large-scale product developed from the “binding band unbundling apparatus” disclosed in Japanese Patent Laid-Open No. 7-277313, which is complicated and expensive to manufacture. There is.
5. Japanese Patent Laid-Open No. 7-101427 discloses a “binding band cutting device”. This is a type in which a shredding device called a freely movable cutting head is installed on the upper part of the gate-shaped frame, cuts by detecting the binding band from the package that passes through the gate, and shreds while pulling it in. ing. The difficulty of securing the capacity of the dust box, which is a weak point of this type, is taken by a method in which fine fragments are carried to the dust box by a suction duct using wind pressure and stored. However, this also causes problems in the complexity of the mechanism, the increase in manufacturing cost, and the space for installation.

As described above, the five have drawbacks such as complicated handling that is not easy, high price due to complicated mechanism, and problems of installation and storage space due to large size.

  In many sites where an actual binding band shredder is required, there are far more cases where a large number of small packages must be unpacked. , Poles, applications will be limited to a limited range. In addition, the special functions assigned to each make the handling complicated, and the most important and necessary elements that are compact, easy to handle, easy to move, and easy to handle are missing. There is a problem.

  The problem to be solved is to obtain a binding band shredder that can be produced at low cost without having a complicated mechanism, is compact and easy to handle, can be easily moved anywhere, and can be easily handled by anyone.

  In the present invention, a sensor installed between two closely-fed rollers for feeding a binding band senses that the binding band has been turned on and is turned on in a direction perpendicular to the bevel gear attached to the output shaft of the motor. Dividing the rotational force, driving the roller, pulling the binding band, the rotary blade attached to the rotary blade support shaft at the tip of the bevel gear attached to the output shaft of the motor, and two bearings supporting both ends of the roller This is a binding band shredder that has a fixed blade attached to the lower part of the support plate and chops the rotating blade that rotates at a high speed by rotating the motor and a fixed band between the fixed blade.

The present invention drives a roller that divides the power of one motor by a bevel gear and pulls the binding band, while turning a rotating blade that shreds the binding band,
1. Due to the simple structure, the manufacturing price is low.
2. Because it is lightweight and compact, it is free to carry and can be easily moved anywhere.
3. Since it can be operated simply by inserting a cable tie into the band slot, anyone can use it easily.
4). By simply increasing the number of rollers and fixed blades, multiple simultaneous processing type shredders that can shred multiple binding bands from multiple directions at the same time without increasing the number of motors and rotary blades are easy. I can do it.
There are advantages as described above.
