The lift table 15 is raised and a truck 1 is retracted to pull out the wire 13 grasped by the second pawl 18 from the compressed old paper 12.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a packing wire cutting and removing device for cutting and removing wires that bind a package of compressed waste paper or the like.

[Conventional technology]

After waste paper such as newspapers and magazines is collected, it is compressed into a rectangular parallelepiped of about IX x 2 m, and its sides are tied with multiple wires to make compressed waste paper. This compressed waste paper is transported, crushed by a crusher at the 2nd Seigi factory, melted, and recycled.

In order to supply the waste paper to the crusher, it is necessary to remove the wire from the compressed waste paper.

Conventionally, wire removal from compressed waste paper was done manually by two workers. That is, one worker cuts the wire with a scissor-like cutting tool, and then pulls the wire out of the waste paper by hand.

However, the wire cutting and removal work performed by such workers is dangerous and hard work, and is also undesirable from a sanitary point of view due to the poor working environment.

A device that mechanically cuts and removes wire from compressed waste paper.

This method has been proposed in JP-A-60-110633 (wire removal device for compressed waste paper) and JP-A-60-110634 (wire cutting device for compressed waste paper, etc.). The device proposed in these publications compresses waste paper almost in the center of one side.

A cutting device that cuts the wire that horizontally binds this compressed waste paper.

It is equipped with a hook that picks up and removes the wire on the opposite side of the compressed waste paper. The cutting device used here is equipped with a pair of toothed plates having sharp teeth arranged in rows, and the pointed tooth tips of the toothed plates are inserted into the compressed waste paper and rubbed together. This is used to cut the wire.

(Problems to be Solved by the Invention) However, with such conventional devices, a complicated structure must be used as the cutting M device, and furthermore, there is a problem that the wire may escape during cutting, resulting in poor cutting. There is.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a packing wire cutting and removing device that can reliably cut and remove the wire, although it has a conventional structure.

[Means for solving problems]

The present invention is an apparatus for cutting and removing a wire that binds the side surface of a package. a first claw provided with an extending blade; a twenty-eighth which is held on the lifting platform so as to face the first claw and which is provided with a mechanism for gripping the wire of the package; and the first claw and the twenty-eighth. The gist of the present invention is a packaging wire cutting/removal device having a clamping mechanism for bringing at least one of the two close to the other and clamping the package between the two.

[Effect]

The wire cutting and removing operation by the packing wire cutting and removing device having the above structure is performed as follows: First, the vicinity of one end of the rectangular parallelepiped package is clamped with the first claw and the second eighth. As a result, the blade of the first claw comes into contact with a plurality of wires that bind the side surface of the package substantially horizontally, and damages the wires. However, since the blade is simply pressed against the wire, the wire is not likely to be cut immediately.
Raise the platform. Due to this.

The part of the package clamped by the first claw and the second eight is lifted, and the weight of the heavy package is applied to the wire in the part that is in contact with the first claw, and the wire breaks. Grip the wire. After that, the clamp of the package by the first claw and the second eighth is released, and the second eighth is moved by moving the lifting platform, and the wire gripped by the second eighth can be pulled out from the package. .

〔Example〕

The present invention will be described in detail below with reference to the eight drawings.

FIG. 81 is a plan view showing an embodiment of the present invention, FIG.

FIG. 3 is a side view thereof showing different operating states, and FIG. 4 is a front view thereof. In FIGS. 1 to 4, 1 is a self-propelled trolley, and 2 is a support column attached almost perpendicularly to its tip. The strut 2 is pivotable about a horizontal axis about a fulcrum 3 near its lower end, and is connected to a hydraulic cylinder 4 for pivoting the strut 2. Reference numeral 5 denotes a lifting platform that is held movably up and down by the support 2, and 6 refers to a lifting platform a that raises and lowers the lifting platform 5.
A hydraulic cylinder composing the structure, 7 is a bracket attached to the front center of the lifting platform 5, and 8 is a first claw attached to the tip of the bracket 7. The first claw 8 may have a simple structure with blades 8A extending approximately vertically at both ends thereof.
Reference numeral 9 denotes a pair of arms disposed on both sides of the first claw 8, which are held movably horizontally with respect to the lifting platform 5 so that they can approach or move away from the first claw 8. ing. 1 is a hydraulic cylinder that horizontally reciprocates each arm 9; 12 is compressed waste paper;
3 is the wire that ties the sides of the compressed waste paper. The hydraulic cylinder 11 connects the second claw 10 with the first pawl 8 via the arm 9.
This is to clamp the compressed waste paper 12 between the first claw 8 and the second claw 10, and constitutes a clamping mechanism.

Next, the No. 28 10 will be explained in detail with reference to FIGS. 5 and 6. The second eight 10 includes a pair of main claw plates 15.15 extending in the vertical direction, and an auxiliary claw plate 1 disposed between them and movable in the longitudinal direction (therefore, vertically) with respect to the main claw plates 15.
6. The natural nail @15 has a plurality of first protrusions 15A that protrude laterally at regular intervals.

The cross section of the protrusion is good as shown in Figure 5 (as can be seen, the tip is sharpened. This allows the first protrusion 15A to be attached to the compressed waste paper
It can be easily inserted into the side of 2. Furthermore, the first protrusion 15A
on either the upper or lower edges (in this example, the upper edge).

A recess 15B for gripping the wire 13 is formed. The auxiliary claw plate 16 also has a second protrusion 1 corresponding to the first protrusion 15A.
It has 6A. The second protrusion 16A has a recess 16B for gripping the wire on the edge opposite to the recess 15B of the first protrusion 15A, and a slope 16C for pushing out the wire in the recess of the first protrusion on the opposite side. is formed.

Furthermore, as shown in FIGS. 2 to 4, a hydraulic cylinder 17 is connected to the auxiliary pawl plate 16 and is configured to be driven up and down.

Regarding the packaging wire cutting and removal device having the above configuration.

The operation will be explained below. Compressed waste paper from which wire should be removed 1
2.12 are placed at appropriate intervals as shown in the first WJ. Next, the cart 1 is driven to position the first claw 8 at the tip between the two compressed waste papers 12. At this time, keep the arm 9°9 wide (open) so that the second claw 10. put.

Next, the hydraulic cylinder 11 (see FIG. 4) is operated to move the arm 9.9 inward. As a result, each compressed old w
112 is clamped by the first claw 8 and the second claw 10,
The wire 13 on the side surface of the compressed waste paper 12 is strongly pressed against the blade 8A of the first claw 8 and is damaged. On the other hand, in the second wind lO, as shown in FIG.
The first protrusion 15A and the second protrusion 16A are inserted into the side surface of the compressed waste paper 12, as shown in FIG. Here, since the first protrusions 15A are multi-layered, no matter where the wire 13 is located, it will be located between the adjacent first protrusions 15A, 15A.

Next, with the first claw 8 and the second wind lO clamping the compressed waste paper 12, as shown in FIG.
At the same time, the support column 2 pivots backward around the fulcrum 3. As a result, the compressed waste paper 12 is lifted with the vicinity of one end thereof being clamped by the first claw 8 and the second claw 10, and is slightly rotated. Therefore, the load of the compressed waste paper 12 is applied to the portion of the wire 13 clamped by the first claw and the second claw, and the wire 13 damaged by the first claw 8 breaks at that position. In this way, the wire 13 binding the compressed waste paper 12 can be reliably cut. Note that it is possible to cut the wire 13 by raising the lifting platform 5 to Ik without rotating the support 2, and therefore a structure in which the support 2 is fixed may be used. When the wire 13 is turned, a larger load is applied to the wire 13, which has the advantage of ensuring that the wire breaks more securely.

Next, after breaking the wire, the hydraulic cylinder 17 is operated to move the auxiliary claw plate 16 downward. As a result of this movement, the recess 16B at the lower edge of the second protrusion 16A of the auxiliary claw plate 16 catches the wire 13 and moves downward, and as shown in FIG. Press it on 15B.

(Then, the wire 13 connects the first protrusion 15A and the second protrusion 16A.
It is grasped by. Note that this operation may be performed before cutting the wire, but it is better to perform it after cutting.

Since the compressed waste paper is somewhat loose, the auxiliary claw plate 16 can be easily moved, which is preferable.

After gripping the wire 13 with the second claw 10, the clamp of the compressed waste paper 12 by the first claw 8 and the second claw 10 is released,
The wire 13 held by the second claw 10 is pulled out from the compressed waste paper 12 by raising the lifting platform 5 and moving the nine-carriage 1 backward. After pulling out the wire 13, the nine-carriage 1 is driven to remove the wire 13. Transfer to the designated location.

At that position, the grip of the wire 13 by the second wind lO is released. This release is performed by raising the auxiliary claw plate 16 as shown in FIG. That is, when the auxiliary claw plate 16 is raised, the slope 16C of the upper edge of the second projection 16A pushes out the wire 13 located in the recess 15B of the first projection 15A from the recess 15B, thereby releasing the wire. With this, one wire cutting and removing operation is completed.

In addition, in the above embodiment, the first claw 8 is provided at the center of the lifting platform 5.
The second claws 10 are arranged on both sides of the paper, and the wires of two pieces of compressed waste paper 12 can be cut and removed at the same time. However, the present invention is not limited to this structure.
It is also possible to arrange the first claws on both sides thereof. By arranging the second eighth 10 in the center, there is an advantage that the drive mechanism for driving the twenty-eighth auxiliary claw plate can be shared. Alternatively, only one first claw and one second claw may be provided to remove wire from a single piece of compressed waste paper. The structure 2810 is not limited to the structure shown in 2, but can be modified as appropriate, and has any structure that can press the side of the compressed waste paper and clamp it with the first claw 5 and that can grip the wire. is available.

Further, in the above embodiment, the support column 2 supporting the lifting platform is mounted on the trolley 1, but instead of this, the structure may be such that the support column 2 is fixed in a fixed position and the compressed waste paper 12 is moved by a suitable conveyor. However, if a cart is used as shown in Figure 5, the wire can be cut and removed at various positions by moving the cart without the need for a conveyor to convey the compressed waste paper, and the removed wire can be cut and removed manually. It has the advantage of being able to be transported to a predetermined location without having to be handled.

The embodiment of the present invention has been described above with respect to the case where it is applied to the removal of wires that bind compressed waste paper.9 The apparatus of the present invention has the following features:
In addition to compressed waste paper, it can also be used to remove wire rings from valves, cotton, etc., and from any packaging.

〔Effect of the invention〕

As explained above, the present invention is configured such that the lifting platform holding the first claw and the second eighth can be raised while the package is clamped by the first claw and the second eighth. , by lifting the package with the first claw pressed against the wire of the package and applying the weight of the package itself to the wire,
Can break wire. For this reason.

The first claw used to break the wire should have a simple structure with a blade on the jl (this can simplify the device. Also, the second claw has the function of gripping the wire). So by moving this 28th.

The wire can be pulled out of the package and removed.

In this way, there is an advantage that the wires from the package can be safely removed without having to be done manually.
