JPH06247414A - Tucking-in device of material in wire coil automatic packer - Google Patents

Abstract

PURPOSE:To prevent interference with a cradle roll when applying a half coil, by providing a plurality of stoppers with a reduced diameter in a wire coil automatic packer composed of a plurality of tucking-in arms constituted by a ring structure. CONSTITUTION:Tucking-in carriers 1, 2 are positioned at the retreated limit and tucking-in arm 8 is fully opened. The tucking-in carriers 1, 2 are moved forward and the tucking device is transferred to the endface of the cradle roll 5 to close the arm at the upper face position of the cradle roll 5. Subsequently, after the tucking-in arm 8 is contracted up to the upper face of the cradle roll 5, the tucking-in carriers 1, 2 cease to move forth and the tucking-in arm 8 opens fully and then a material is inserted in the inside of the wire coil 3. And the cradle roll 5 is rotated in the opened state of the tucking-in arm 8 up to non-interference position at the inner face of the wire coil 3. Finally the coil 3 is made flexible and the material is packed with the coil 3. And hence, a high grade winding-up on a material can be applied.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arm opening / closing drive of a packing material folding device in an automatic wire coil coil packing device.

[0002]

2. Description of the Related Art Conventionally, a wire wound in a coil shape and bundled and bundled is temporarily stored in a warehouse or an inventory area after being hot-rolled, and then shipped to customers.
Wire rod coils that have been bound, weighed, etc. are susceptible to scratches and the like due to contact between the coils, so when transporting within the factory or stacking cargo by sea freight shipped from the factory. During land transportation by a car or car, wire flaws during cargo handling, product flaws during stacking, and abrasion flaws occur. Particularly in recent years, as the quality of products becomes higher, surface flaws and the like during transportation have come to be considered to be a problem, and for that reason, packaging has become necessary. As a countermeasure, despite the heavy work such as preparation of materials, winding, folding, and bundling of the wire rod in order to perform the packing work, the packing work of the wire coil is actually done manually. Is.

[0003]

For this reason, the inventors have been developing an apparatus for automatically bundling and packing wire rod coils in succession. When using a stepped expansion / contraction arm, the height of the wire coil changes when folded, especially in the case of a half coil, it cannot be folded at the optimum point due to interference with the cradle roll and it cannot be folded at the optimum point. There is a problem that it will interfere with the coil if it is left open during rotation, and that the package cannot be secured if it is left closed.

[0004]

As a result of intensive development, the inventors of the present invention, which should solve the above problems, can prevent the fluctuation of the wire coil height, especially the interference with the cradle roll in the case of a half coil. In addition, the purpose is to interfere with the coil that occurs when the coil of the built-in taping rotates and to secure the packing form. The gist of the invention is that, in a wire rod coil automatic packing apparatus composed of a plurality of folding arms configured by a ring mechanism, a plurality of diameter reduction stop mechanisms are provided, and the material folding in the wire rod coil automatic packing apparatus is characterized. On the device.

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a view showing a fully opened state of a folding arm in a retracting limit of a folding carriage according to the present invention. In the device of the present invention, as shown in FIG. 1, the wire rod coil 3 is placed on a pair of cradle rolls 5, and a packing sheet 4 is wound around the wire rod coil 3. The folding carts 1 and 2 are located at the backward limit, and the folding arm 8 is in a fully opened state, which is a so-called first stage. Reference numeral 6 is a folding arm stopper actuator, and 7 is a folding arm opening / closing actuator. FIG. 2 is a view showing a state in which the folding carriage according to the present invention has advanced to the cradle roll side end. As shown in FIG. 2, the folding carriages 1 and 2 move forward, the folding device moves to the end surface of the cradle roll 5, and the forward movement of the folding carriage is stopped.

FIG. 3 is a view showing a state in which the folding arm according to the present invention is closed at the upper surface position (second stage) of the cradle roll. That is, as shown in FIG. 3, the folding arm 8 converges and closes to the upper surface of the cradle roll. At that time, the folding arm 8 is closed by the folding arm opening / closing actuator 7. FIG. 4 is a view showing a state in which the packing sheet in the apparatus according to the present invention is folded into the wire coil inner diameter portion. That is, in the above state, as shown in FIG. 4, the folding arm 8 is fully closed (third stage) as it approaches the position 100 mm from the coil end face, and the material is pushed into the wire coil inner diameter portion. At this time, the folding arm 8 is closed by the folding arm opening / closing actuator 7.

After folding in the state of FIG. 4, the arm is opened to the first stage and the material is pressed against the inner surface of the coil. Then, the coil 3 is rotated by the rotation of the cradle roll while the folding arm is closed to the minimum non-interference position (fourth stage) on the inner surface of the wire coil, and the material is made to conform to the inner surface of the coil in the rotating direction. At this time, the folding arm 8 is closed by both the folding arm opening / closing actuator 7 and the folding arm stopper actuator 6.

FIG. 5 is an explanatory view showing the opened / closed state of the pushing arm. In this way, the folding carriage is in the backward limit position and the folding arm is in the fully opened state in the first stage (A), and the folding carriage is moved forward and the folding device is moved to the end surface of the cradle roll and is closed at the top position of the cradle roll. In the second step (B), the arms are converged to the upper surface of the cradle roll, and then the folding carriage is stopped to move forward. The third step (D) in which the folding arm is fully closed is performed, and the material is pushed into the wire coil. Then, the coil is rotated by the rotation of the cradle roll while the folding arm is opened up to the fourth stage (C), which is the minimum non-interference position on the inner surface of the wire rod coil, and the material is made to conform to the inner surface of the coil in the rotation direction. This operation is completed by packing the material in the coil.

[0009]

As described above, according to the present invention, it is possible to prevent the height variation of the wire coil, especially in the case of the half coil, from interfering with the cradle roll, and it is possible to fold the material satisfactorily. The present invention has an extremely excellent effect in that high-quality winding can be performed without sagging or fraying.
