Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a wire removal device for removing wires that bind compressed waste paper or the like, which removes the wires after they have been cut.

After waste paper such as newspapers and magazines is collected, it is formed by a waste paper company into a rectangular compressed waste paper 10 of about 1 x 1 x 2 m as shown in FIG. 1, and is usually bound with five wires 12. This compressed waste paper is transported, crushed by a crusher at a paper mill, and then melted and recycled. When using the crusher, it is necessary to remove the wire from the compressed waste paper.

A removing device 14 shown in FIG. 2 has been devised as a device for performing this work. This device 14 detects compressed waste paper 10 transported by a conveyor 16 with an optical sensor 1.
8, the wire 12 is detected and stopped at approximately the center of one side of the compressed waste paper, and the wire 12 is cut by the cutting device 20 (see FIGS. 3A and B). Next, the wire 12 is cut at the corners 2 at both ends of this side.
2, the wire 12 is separated from the corner 22 by a loosening device 24 (see C in the same figure), and then taken off from the opposite side by a pulling device 26 (see D in the same figure). In this work, the wire 12 is separated from the corner 22 because the wire 12 is still attached to the corner 22 if only the wire 12 is cut.
This is because it is not possible to take it away with the taking-off device 26 because it is biting into the body. In addition, the collection device 2
The contact between the corner 28 on the 6th side and the wire 12 does not interfere with the work in any way.

The present invention mainly relates to the take-off device 26 used in the removal device 14.

BACKGROUND TECHNOLOGY Although various configurations are conceivable for this take-up device, no one that is fully satisfactory is known yet. For this reason, this removal work is currently carried out manually by pulling out the wire with a hook.

Problems to be solved by the Invention Since the wire is in a loose state on the verge of falling and its position is uncertain, this pulling device must be able to reliably pick up the wire regardless of its position.

In addition, the collected wire must be packed into a sufficiently small size so that it can be easily disposed of as scrap. In the conventional manual method, the removed wire is long and very bulky, and scrap companies cannot take it as it is.

It is an object of the present invention to realize a take-up device that satisfies these demands and has a simplicity suitable for practical use.

Means for Solving the Problems The present invention provides a pin group consisting of a plurality of pins extending substantially parallel to each other, supports this pin group, and positions each pin tip at a position near a cut and loosened wire such as compressed waste paper. A movable table is provided on the pin group, and the pin group is rotated while pressing the tip of the pin against compressed waste paper, etc., and the wire is hooked on the pin and taken up, and the wire is wound around the pin group. This is a wire removal device for compressed waste paper, etc., characterized in that it has a rotating device for attaching the wire.

This wire pulling device is further provided at a side position of the pin group of the movable table, and when pulling the wire,
It may also include a pressing part that presses the wire against the surface of compressed waste paper or the like and applies tension to the wire.

In addition, this wire pulling device, after winding the wire,
It may also include a push-out portion that advances along the pin toward the tip of the pin and removes the wire from the pin group.

Function The pin group of this wire take-off device rotates by pressing the tip of the pin approximately perpendicularly to the surface of compressed waste paper, etc., and hooks the wire and wraps it around the take-up pin group. At this time, if there is a pressing part, tension is applied to the wire, making the winding more stable and the winding smaller. Additionally, the presence of the extrusion section automates the process of pulling out the wire from the pin group.

EXAMPLES The present invention will be specifically explained below with reference to examples shown in FIGS. 4 to 6. This take-off device 30 is installed in place of the take-off device 26 of the wire removing device 14, and has a movable base 34 mounted on rails 32, 32, and a female thread 3 at the bottom of the movable base 34.
By rotating a screw shaft 38 screwed into the compressed waste paper 10 by a motor 40, the movable table 34 moves on the rails 32, 32, approaching and separating from the compressed waste paper 10. Mobile platform 3
4, five geared motors 42, . . . are installed at the height of each wire 12 of the compressed waste paper 10, and each of these geared motors 42, .
A pin group 48 consisting of four pins 46 projecting approximately parallel to the front, that is, toward the compressed waste paper 10, is provided on each disk 44 along its peripheral edge. The entire front surface of the movable table 34 except for the disk 44 portion is covered with a front plate 50, and near both ends of this front plate 50 there are pressing parts 52, 52 made of pipes extending vertically.
is provided and elastically protrudes from the front plate 50 by springs 54, .
Press 2. Furthermore, a limit switch (not shown) is provided at the base of one of the springs 54, . Detect summer weather. Front plate 50
is attached so as to be movable back and forth by inserting a rod 58 into the tip of the arm 56, . It is pressed so that the front surface is flush with the disk 44. Behind the rod 58 are columns 64, 64 having stoppers 62, .
are provided, and when the movable table 34 moves rearward, the rear ends of the rods 58, . . . come into contact with the stoppers 62, . The outer peripheral portion of the disk 44 of the front plate 50 is the extruded portion 6
4, and when the moving table 34 moves backward, it moves along the pin 46 toward the tip of the pin, and the pin group 4
Remove the wire wrapped around the outer circumference of 8. A door 66 is provided on the sides of the movable table 34, front plate 50, etc., and when the movable table 34 retreats, it moves to the front of the front plate 50,
The wire removed from the pin group 48 is prevented from falling onto the conveyor 16 that transports the compressed waste paper 10. A slope plate 68 is provided at the bottom of the door 66 to prevent falling wire from getting on the rails 32, 32. Furthermore, a control device (not shown) is provided which performs the following operations.

Since this take-up device 30 has the above configuration, it operates as follows. After cutting the wire 12 of the compressed waste paper 10 with the cutting device 20 and loosening it with the loosening device 24,
While operating the geared motors 42, . . . to rotate the pin group 48, the movable table 34 is advanced,
The tips of 6, . In this way, the pin group 48 takes over the wire 12 while winding it around its outer periphery. At this time, the wire 12 is rotated by the rotating pin group 48.
Since the wire 12 can be wound up as long as it is caught on the pin group 48, the wire 12 can be reliably wound up by the pin group 48, regardless of its position. The moving table 34 stops, moves backward after several seconds necessary for the winding, and after the door 66 moves and covers the front surface of the front plate 50, the rear end of the rods 58, . the front plate 50 only stops, and the extrusion part 64 of the front plate 50 contacts the pin group 4.
8. Pull out the wire wrapped around ... and let it fall. In this way, the moving table 34, geared motor 42, .

In addition, when the pin group 48 winds up the wire 12, the pressing part 52 presses the wire 12 against the compressed waste paper 10 and applies tension to the wire 12, so that the wire is wound more tightly, that is, smaller. Therefore, it is possible to configure the take-up device of the present invention without this pressing portion.

Further, in this embodiment, the wire wrapped around the pin group is removed by the extrusion part, but it goes without saying that the wire can be removed by other methods, such as a method of deforming the entire pin group into a thinner one.

Further, in the above example, a geared motor is provided for each pin group as a rotating device for rotating the pin group, but it goes without saying that devices with other configurations can also be used.

Effects of the Invention As described above, the wire pulling device of the present invention presses a group of pins approximately perpendicularly onto the surface of compressed waste paper, rotates the device, hooks the wire onto the pin, and wraps the wire around the group of pins. Therefore, the wire will be wound up as long as it is caught on one of the rotating pins in the pin group.
Even if the wire is loose and is not in a fixed position, such as compressed waste paper, it can be reliably picked up. Moreover, since the wire is wrapped around the pin group and has a compact shape, it is not bulky and can be processed as scrap as is.

Furthermore, by adding a pressing part, it is possible to apply tension by pressing the wire against compressed waste paper, etc. when pulling the wire, and winding it around the pin group is performed well, stabilizing the work and making the wire more compact. Can be summarized.

Furthermore, if a push-out part is added, the wire wound around the pin group can be automatically pulled out, making it more convenient.
