Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an apparatus for cutting and removing binding cords for binding old newspapers, magazines, and other general waste paper into bundles of a certain size from the bundles.

BACKGROUND ART Conventionally, waste paper such as old newspapers and old magazines discarded from ordinary households is mainly bound with synthetic resin strings, taking into consideration the convenience of carrying. These items are collected by waste collection companies and purchased by bulk companies. Here, waste paper etc. is sorted,
The paper is separated into similar types of paper and sent back to the paper manufacturing company. Binding companies are concerned that contamination with binding strings, especially synthetic wood strings, will have a negative impact on remanufactured paper.
It is removed prior to the sorting operation. However, the bundles come in various sizes, and there is no cutting machine that can handle them, so it is necessary to manually cut each string individually and pull out the string pieces.
It was being removed.

Problems to be Solved by the Invention A cutting device that operates to suit waste paper binding blocks such as old newspapers of various sizes and cuts the binding strings without omission; To provide a device for automatically removing a string from a bundle of waste paper without manual intervention by developing a string take-up wheel for hooking and winding the string.

Means for Solving Problems This invention's string cutting and string removing device consists of a moving conveyor that arranges and moves large and small bundled waste paper blocks of old newspapers, old magazines, etc., bound with string, and the moving conveyor. The moving conveyor is located at a suitable location above the shaft and supports a rotary transmission shaft and a hollow tube shaft concentrically on the inside and outside, having an axis that is approximately perpendicular to the transverse direction. A required number of arms rotatable around a shaft are supported in rows at required intervals, each arm rotatably bears a support shaft parallel to the axis of the tube shaft at the tip thereof, and each support shaft and the rotation transmission shaft are connected to each other. Attach sprocket wheels in correspondence with each other, apply a chain to the sprocket wheels, rotate each support shaft in a driven manner, and attach a disc cutter to both ends or one end of the support shaft.
A string cutting cutter, each of which ascends independently to follow the cut surface of the bundled waste paper mass, and a support shaft supporting the required number of star-shaped blades in horizontal rows at the required intervals corresponding to the end of the moving conveyor. , which has a rotational transmission mechanism associated with one end of its support shaft, and a string puller which brings the tips of each blade into rotational contact with the delivered bundled waste paper mass and wraps the binding string around it.

Effect Since the means of the invention is constructed as described above,
A bundle of waste paper made by binding old newspapers, old magazines, etc. with string is fed to the starting end of a moving conveyor. The stacked bundled waste paper blocks move along with the moving conveyor, where they come into contact with disc cutters supported at the ends of rows of arms. There, the surface receives cutting scratches and the binding cord is severed. Each arm is rotatable around its base, so it moves up and down according to the size of the bundled waste paper mass.
Make cutting marks on the surface. In this way, the binding cord is cut by the multi-blade row cutter. The bundle of paper bundles then moves to the end of the moving conveyor, where, when sent out, it comes into contact with a string take-up wheel rotating at high speed from the bottom, and the binding string is caught and wound up.
There, the string is removed from the bundled waste paper mass. The bundled waste paper mass is separated and sent out. After completing the string retrieval work for a certain period of time, the device is stopped and the retracted string is cut and removed from the reel wheel.

Embodiment The string cutting and string removing device 1 as an embodiment of the present invention can also directly feed the bundled waste paper blocks 39, but for large-scale processing, it is possible to use a device that can sequentially feed a predetermined amount at a constant rate. It is supplied by the feed conveyor 2. Then, each binding string is cut and tied, and then sent via a sorting conveyor 3 or directly to a large block binding machine (not shown).

Reference numeral 9 denotes a moving conveyor, which is installed on the table frame 4 so as to be inclined upward in the front, and whose starting end is connected to the feeding conveyor 2.
A front wall 7 and upper half side walls 8, 8 are provided at the input section corresponding to the terminal end of the input section, and continuous with the side wall 6 provided at the front end of the side frames 13, 14. Then, it receives the bundled waste paper mass 10 fed from the feeding conveyor 2, places it thereon, and moves it to the terminal end side. Reference numerals 11 and 12 indicate first and second multi-blade horizontal chain cutting cutters in which disk cutters are arranged in rows at a required interval, and they move back and forth on the transfer conveyor, and two or more disk cutter blades are not arranged in tandem in the traveling trajectory. Arranged at intervals.

To explain the first multi-blade horizontal chain cutting cutter 11 with reference to FIGS. 3 and 4, the side frame 1
Transmission shaft bearings 15 and 16 are mounted on 3 and 14, and a rotating transmission shaft 17 is supported thereon. Centering around this rotary transmission shaft 17, a hollow tube shaft 18 is placed on the outside thereof.
A bracket 19 separate from the bearings 15 and 16,
It is fixedly supported by 20. The base is externally fitted onto the tube shaft 18, and a large number of arms 21, which are entirely rotatable around the axis of the tube shaft 18, are mounted at required intervals. A support shaft 22 having an axis parallel to the tube shaft 18 is rotatably supported, and sprocket wheels 23 and 24 are attached in correspondence with each support shaft 22 and the rotation transmission shaft 17, and the sprocket wheel A chain 25 is stretched between 23 and 24 to transmit the rotation of the rotation transmission shaft 17 to each support shaft 22 at the tip of each arm 21.
Disc cutter 2 is attached to the protrusion from both ends of the arm.
6 is attached and rotated at a high speed, for example, several tens of times the transfer speed of the moving conveyor 9. Each arm 2
1 rotates its tip to a low position by the action of gravity, and a stopper bar 27 is provided across the side frames 13 and 14 so that the lower edge of each disc cutter 26 does not come into contact with the moving conveyor 9. collide with this and prevent it from falling further downwards. A cushioning rubber 28 is attached to the arm collision portion of the stopper bar 27.

A side space collar 29 and an intermediate space collar 30 are fitted onto the tube shaft 18, and the arms 21 are set at a predetermined distance from each other.

Reference numeral 31 denotes a string puller, with bearings 32 and 33 attached to the ends of the side frames 13 and 14, and a support shaft 34 attached to this.
On this support shaft 34, string blade blades 35 are formed in a star shape, the edges of which protrude in a star shape at required intervals, and the rising edge on the rotation direction side has a blade. Appropriate depth in the axial direction at the bottom of these intermediate valleys,
Blade plates 37 provided with cutter insertion grooves 36 are welded onto the hollow shaft 38 at required intervals, and are fitted and fixed onto the support shaft 34.

A hood 40 is attached to the rear ends of the side frames 13 and 14, and is provided from a first movable part 42 and a second movable part 43 to a fixed part 41, and is wrapped around the strap pulley 31. When the binding string 39 is removed, it is provided so that it can be movably stored outside the fixed part 41 around the movable part attachment shaft 44.

Effects of the Invention Since the device of this invention is as described above, if it is connected to, for example, a feeding pit, collected bundled waste paper blocks can be inputted at once, sequentially fed by a feeding conveyor, and bound one by one. The cord can be removed by cutting it, winding it up, and removing it, which has revolutionary effects such as eliminating heavy manual labor.
