Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wire coil binding device for compressing and binding wire coils.

(Conventional technology) Conventionally, when wire rod coils were to be bundled into large bundles at a wire rod manufacturing factory, several small bundled coils were temporarily stored using a crane or forklift, and compressed into large bundles, which made the work discontinuous. The work efficiency was extremely low and required a lot of effort. Therefore, in order to make the large-scale tying work continuous and labor-saving, the applicant proposed in Japanese Patent Publication No. 1983-5716 that the compression frame provided on the base and the support of the pyra were connected by a connecting body, and this connecting body and the base were connected. A guiding groove is formed in the guide provided on the pyra's arm and a stop plate that supports the arm to allow the binding material to run, and the binding material is sent out from the binding head provided on the compression binding plate movably provided on the base. We proposed a device for bundling small bundled coils supported on an arm into a large bundle using a material.

(Problem to be Solved by the Invention) However, in the above-mentioned bundling device, it is necessary to take the wire transported by the hook conveyor down from the hook, bundle it on the flat conveyor, and then hook it back onto the arm of the piler using a jump lever or the like. be. However, in a wire manufacturing factory, the coils are conveyed through the factory by a hook conveyor, so it is most desirable to tie the coils directly with the coils hooked to the conveyor hooks, or to tie the coils by removing them from the hooks as described above. The equipment was inferior in terms of working efficiency. Therefore, attempts were made to tie the coils while hanging them on the conveyor hooks, but the hooks got in the way and it was not possible to tie the topmost part 1a of the coils as shown in Figures 1 to 3. , a single horizontal letter, a Y-shape, or an X-shape. In the figure, 1 is a coil, and 2 is a binding material. However, as the size of the coil bundle increases,
In other words, from the viewpoint of ease of material handling after bundling, the method of bundling large coils by gathering multiple small coils or bundling large coils (each weighing 2 tons) at once has been adopted. As shown in FIG. 4 or FIG. 5, there is a growing need for coils in which the uppermost part 1a, which is the suspension point of the coil, is bound and the coils are bound at three or more points.

This invention solves the above-mentioned conventional problems.The present invention efficiently produces bundled coils with excellent packaging by compressing and binding the coils while they are hooked on hooks and binding them at multiple points including the top of the coils. It is an object of the present invention to provide a wire rod coil binding device that can be obtained in a number of ways.

(Means for Solving the Problems) In order to achieve the above object, in the binding device of the present invention, a binding material guiding arm is provided at multiple locations including the upper surface of the arm of the hook for transporting the wire coil in the longitudinal direction of the arm for guiding the binding material. A notch that can be freely engaged and detached from the tip of the hook and a compression plate that presses the coil supported by the notch are attached to a compression frame fixed on a base so as to be able to move forward and backward. A holding plate that holds the coil against the pressing force of the compression plate is disposed on the base opposite to the compression plate, and a curved part of the hook is connected to a groove on the upper surface of the arm of the hook. The holding plate is provided with an end groove that communicates with the rear end of the groove of the hook, and the compression plate is provided with a groove that communicates with the front end of the groove of the hook and a binding head. A guide is provided to guide the binding material sent out from the binding head to the end grooves of the hook and retaining plate.

(Function) In the binding device of the present invention, the holding plate holds the hook with the coil hooked onto the arm, and the hook engages with the tip of the hook to position the hook. The compression plate driven in the forward direction compresses the coil between it and the holding plate, and in this compressed state, when the binding material is sent out by each binding head, the binding material is guided by each guide and hits each of the hooks and the holding plate. It travels at high speed through the end grooves, the grooves in the hook arms, and the grooves in the compression plate and returns to each bundling head. After that, by performing known binding operations such as pulling back the coil using the binding head, moving the coil to the vicinity of the outer diameter of the coil, and securing and cutting both ends of the binding material using a sealing material, etc., the coil in the compressed state includes the top part of the coil. It is concluded at multiple points. By retracting the hook and the compression plate and separating the hook from the holding plate, the coil hooked to the subsequent hook can be compressed and bound.

Further, although the inclined side portion of the curved portion 7 of the hook is designed to function as an upper guide for the binding material, a separate upper guide may be provided depending on the shape of the hook.

In order to bind the coils using the device configured as described above, first, the holding plate 15 is moved back to the position shown by the chain line 61 by the hydraulic cylinder 16, and the side guides 41 and 42 are moved by the pneumatic cylinder 48.
is rotated to a horizontal state as shown by a chain line 62.
An appropriate number of small bundles of coils 1 (three in this embodiment) are placed on an arm 5 on a hook conveyor line (not shown).
The hook 3 hooked onto the device is moved horizontally from the side of the device in the direction of arrow A and stopped at the binding position shown in the figure. Next, when the holding plate 15 is advanced by the hydraulic cylinder 16 and the notch 34 is projected by the hydraulic cylinder 36, the curved portion 7 of the hook and the guide groove 17 of the holding plate are engaged, and the notch 34 and the notch hole 35 are engaged. Accordingly, the hook 3 is held in a predetermined position on the base 10. Further, the side guides 41 and 42 are brought into an upright state by the pneumatic cylinder 48. Next, the compression plate 24 is advanced by the hydraulic cylinder 25 to compress the coil 1, and in the middle of this advancement process, the binding head 28 is operated to pull out the binding material from a dispenser (not shown), and the binding material is transferred to the curved part of the hook. 7 and each guide 55, 41, 42, each end groove 18a to 18 of the hook and retaining plate.
d, the coil is made to run at high speed through each of the grooves 6a to 6d in the arm and back to each binding head, so that the entire coil is surrounded by binding material at four points. Further, as the compression plate 24 advances, the pinch rolls of the bundling head 28 are reversed, and the other end of the bundling material held at one end in the bundling head is pulled back, and the pneumatic cylinder 32 moves the bundling head 28 to the outer diameter of the coil. When the binding material is moved to the vicinity, the binding material is pulled out from each groove and comes into close contact with the coil in the maximum compression state, so the binding head 2
After fixing both ends of the binding material with a sealant or the like and separating it from the succeeding part by 8, the binding head 28
is separated from the coil to complete the compression and binding process. Note that while the compression plate 24 is moving forward to compress the coil, the other end surface of the coil is held substantially in a fixed position by the holding plate 15. Next, the compression plate 24, the notch 34, and the holding plate 15 are retracted using the hydraulic cylinders, and the side guides 41, 42 are rotated in the horizontal direction, and then the hook conveyor is driven to remove the large bundled coil. The hook 3 that has been hooked is horizontally withdrawn to the side of the binding device, and the subsequent hook that has hooked the coil to be compressed and bundled is introduced into the binding position shown, and the same process is repeated. In this way, the coils hooked to the hooks 3 are automatically compressed and bundled one after another during transportation, and large bundled coils bound at four points on the top, bottom, left and right can be continuously obtained.

In the above embodiment, the side guides were rotated around the horizontal axis to a position where they would not interfere with horizontally moving coils, etc., but instead of this, the side guides were moved downward, etc. Alternatively, a drive mechanism may be used to move the vehicle away.

Further, in the above embodiment, the case where the hook is moved horizontally has been described, but the hook may be moved up and down to be introduced into and removed from the binding device. In this case, the side guides 41 and 42 may remain fixed in the upright position, and by providing the holding plate 15 with an introduction part that smoothly introduces the descending hook into the guide groove 17, the holding plate 15 can also be mounted on the base. 10
Since the device can be fixedly installed in the device, the device can be greatly simplified.

The above description has been given of the case where small bundled coils are gathered together to make large bundles at four points on the top, bottom, left and right, but this invention can also be applied to large bundles or small bundles of single coils. By changing the number and position of the grooves for guiding the binding material, the position of the corresponding guide, etc., the present invention can also be applied to a binding device that performs binding in an inverted V shape or a line-shaped shape.

(Effects of the Invention) As explained above, according to the present invention, grooves for guiding the binding material are provided at multiple locations including the upper surface of the arm of the hook for transporting the wire coil, and the binding material sent out from the binding head is guided. Since the coils are run through each of the above-mentioned grooves through the guide and returned to the bundling head, it is possible to bind the coils while they are hooked on the hooks while the coils are being conveyed by a hook conveyor, etc., and the coils can be tied at multiple points including the top of the coils. It is possible to efficiently obtain bundled coils with excellent packing appearance.
