Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic convergence device for various long materials having a circular cross section, such as tubes and round bars.

Generally, a long material with a circular cross section (hereinafter referred to as a long material)
For shipping or for collecting separately during the process, for example, for plating, etc., it is usually done by using a U-shaped hook with a wire at the end of a skid, or by pouring into a groove-shaped frame. This work inevitably causes scratches and misalignment due to falling, resulting in loose bundling and the resulting collective transportation, which causes many problems in quality, warehouse storage, and handling due to unstable packaging. are doing. Furthermore, the noise generated by falling objects has been raised as a pollution problem, and countermeasures have been awaited.

A conventional device will be described with reference to FIGS. 1 to 3.

Fig. 1 shows a configuration in which a grooved frame body 2, an inclined rubber plate 3, and a wire 4 are arranged, and a long material 1 is once received by the inclined rubber plate 3 made of an elastic material, and then transported by rolling the inclined surface in the downward direction. This method is effective if treated one by one, but if several pieces are continuously poured, they collide with the preceding long piece 1 on the inclined plate 3, causing noise and misalignment. There are practical problems with the flow.
This device is not suitable for medium diameters of φ200 to φ400.

The method shown in Figure 2 is called the arm swing method, and the arm 5
A group of long materials 1 is received by the groove-shaped frame body 2, and the arm 5
The problem is that it is complicated and expensive, and it is a device that can only enter the long material 1 from the bottom. Although baits with a diameter of 200 to 400 can be used as described above, baits with a small diameter of φ Kazono etc. have some difficulties in delivery.

The one in Fig. 3 is called the A-L reciprocating type, in which the long material 1 rolls on and enters the arm 6 in the frame 2 from the skid terminal, and the arm 6 is pulled out\groove frame 2. Although it can be applied up to about φ100 smoke, it is not suitable for small diameter pipes because it depends on the straightness of the long material 1 and the number of arms, but it will stop midway. In addition, a drawback of this type is that in addition to the installation area, the length of the cylinder + arm pullout length (L dimension) is required, which obstructs the approach of the binding machine for the bundled materials, and is not suitable for manual binding. The scope of work is limited.

The present invention solves the above-mentioned drawbacks, and the present invention is shown in FIGS.
To explain with a diagram, it supports the infeed conveyor 7 (or even only the inclined skids 7I, 72, and 7s are suitable). In this example, there are 9 hexagonal focusing frames8.・82 Furthermore, the bottom frame 9 moves up and down, the lower oblique frame 10 moves the bottom frame 9, the upper oblique side 11 moves the lower oblique frame 10, and the upper oblique side 12 opposite the upper oblique side 11 (moves forward and backward as necessary. In the illustrated state, the device is on standby within the main body 8 and operated by a separate mechanism (not described in detail).

Next, a receiving roller 13.・

．． and a pivot shaft 15.・15. is supported by the frame 16, and the reducer 17.・172, connection shaft 18・chain 9
・Constructed with motor addition.

The stopper 21 at the tip of the feeding conveyor 7 is connected to the rotating arms 14, . The long materials 1 are sequentially stored during operation.

To explain the above in terms of operation, (the stopper 21
(If not supported) Receive roller 13 at the tip of the rotating arm 4I/14.・13. When the receivers are picked up one after another, the difference in arm length of the bundled material for long material work is set to the maximum diameter of the long material 1, 10α, so the material is received obliquely by that difference, and the inclination is reduced by the drive of the motor. When turned in the up/down direction (arrow in the figure), it will move diagonally, roll down, and enter the hexagonal frame, and the lower side will be caught by the lower hypotenuse frame 10 and the upper hypotenuse frame 11, and then it will rotate diagonally. The rows become parallel and settle in a shape that follows the outer peripheral recess of the illustrated long material 1.

This passes obliquely with the upper surface of the long material 1 that is aligned parallel to the lower tier, that is, the straight line of the conveyance line α line, as a plane, and returns to parallel at the crushing control position to follow the concave portion of the lower tier material. It's for a reason. Next, the hexagonal frame lowers by the diameter of the long material 1, stops at the α-ray line, and receives the material, which is repeated.

The above operation is a drawback of the examples shown in Figures 1 to 3.

As a result of dropping the long material l into the frame, scratches, misalignment,
All problems such as noise generation, the suitability or unsuitability of the device due to the diameter of the long material 1, the exclusive area and the obstruction of work access, etc., have all been eliminated. Long and short rotating arm 141.1 with a receiving roller at the tip
