JPS5826719A - Method of taking out long-sized rod - Google Patents

Abstract

PURPOSE:To supply securely rods one by one, by forming axially extended attracting sections in the outer circumferential surface of a roller provided to a delivering section of a rod storing part, and rotating the roller to hold up the rod attracted and supported in the attracting section so that the rod is lifted as a whole. CONSTITUTION:When the intermediate section of a rod (A) stopped at the storing part 4 becomes in contact with the whole of the attracting section 5 of a roller 3, the rod (A) is attracted and supported by the attracting force of the attracting section, and is conveyed by the counterclockwise rotation of the roller 3. Since the size of the width of the attracting section 5 is smaller than the outer diameter of the rod (A), and the attracting force can slightly overcome the weight of the rod, if part of the rod (A) becomes in contact with part of the attracting section 5, the rod (A) would not be attracted, or if the rod is raised in such a way, it will drop before delivered. The attracted rod (A) will be released at the position where it becomes in contact with a guide bar 8.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for taking out long bars loaded randomly in a storage section.

If you want to send the cut metal pipe to any processing machine so that a film is formed on the surface of the cut metal pipe to make it into a product, we will supply the metal pipe one by one to the above processing machine. There is a need to.

By the way, when conveying long bars such as metal pipes to a processing machine, the bars are normally loaded randomly in a storage section and taken out one by one from this storage section.

The method for taking out the bar is described in Mechanical Design Vol. 24 No. 13 ('
October 1980 Extra Issue) P, 20 or Weaving Design Data Book (Published by Nikkan Kogyo Shimbun) 4th edition, P.
As disclosed in No. 17, a discharge passage through which one of the rods can pass is formed at the lower end of the sloping bottom plate of the hopper, an opening is provided in the bottom plate at a position near the discharge passage, and the hopper is attached to the opening. A method of swinging the swinging arm or giving vibration to the hopper to cause the bars in the hopper to flow into the discharge passage, or Easy Labor-Saving Equipment Reader (Published by Nippon Kogyo Wakiwaki) 1st edition P, 95 As disclosed in , one end of a plurality of chain chains arranged in parallel is fixed to form a bar stock portion on the chain.

There has been a conventional method in which the bar loaded on the stock part is lifted by pulling downward from the other end of the child engine and taken out onto a guide provided in front of one end of the child engine.

However, although the former method of taking out hoppers is effective for taking out large diameter, short, and rigid bars, it is difficult to take out long, short, and flexible bars. This cannot be used as a method for extracting long bars because the pieces often become entangled or cross each other.

In addition, the latter method of taking out using a chino lifts the entire bar loaded on the stock, making it impossible to reliably feed one bar at a time. There are drawbacks such as crossing.

Therefore, the present invention eliminates the above-mentioned drawbacks, makes it possible to reliably supply the long bars loaded in the storage section one by one, and also allows the bars to be taken out in parallel without being tilted. The purpose of the present invention is to provide a method for extracting the information.

In this invention, a suction part is formed in the direction of the outer circumferential axis of a roller provided in a discharge part of a bar storage part, and the width dimension of this suction part is made shorter than the outer diameter dimension of the bar material to be taken out, and the suction part The overall suction force is made a little stronger than that of the bar material, and the bar material adsorbed and supported by the suction part is conveyed to the front side of the roller by rotation of the roller in the cutting direction, and at that conveyance position,
This is designed to release the adsorption of the bar material.

Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

As shown in FIGS. 1 and 2, a belt conveyor 1 for transporting long bars is driven by an appropriate drive device, and the conveyor belt 2 moves in the direction of the arrow in FIG. ing.

Above the end of the upper moving part 2' of the conveyor belt 2, a roller 3 is arranged horizontally.

This roller 3 is driven by an arbitrary power and rotates in the direction of the arrow in FIG. 1, and the back of its upward rotation range serves as a storage section 4 for a long bar.

A suction section 5 extending in the axial direction is provided on the outer periphery of the roller 3, the width dimension of the suction section 5 is smaller than the outer diameter dimension of the bar to be conveyed, and the overall suction force of the suction section 5 is as follows. It is slightly stronger against overlapping of the rod-shaped objects.

The suction portion 5 is formed, for example, as shown in FIG.

A recess 6 may be formed on the outer periphery of the roller 3, and a permanent magnet 7 may be fitted into the recess 6 and bonded. In this case, so that the surface of the permanent magnet 7 and the outer periphery of the roller 3 are almost flush with each other,
Attach permanent magnet 7.

The shape of the permanent magnets 7 can be any shape such as a square rod, a rectangle, or a circle, and the number of permanent magnets 7 is determined depending on the stacking of the rod-shaped objects to be transported. When the attraction portion 5 is formed of a plurality of permanent magnets 7, they are arranged in a row with a required interval in the direction of the outer circumferential axis of the roller 3, as shown in FIG.

Note that the number of suction parts 5 is arbitrary, and as shown in FIGS. 3 and 4, they may be provided at regular intervals around the outer periphery of the roller 3. When a plurality of suction parts 5 are provided, a required interval is left between adjacent suction parts 5, and the two are prevented from coming into contact with each other by bending the rod or the like.

When employing such a permanent magnet 7 to form the attraction portion 5, the roller 3 is formed of a non-magnetic material.

Alternatively, an insulating material is interposed between the roller 3 and the permanent magnet 7.

Guide rods 8 are provided in an inclined manner on both sides of the front part of the downward rotation range of the roller 3, and the upper end of each guide rod 8 faces the side of the end of the roller 3 and is suction-supported by a suction part. When the rod-shaped object is conveyed by the rotation of the roller 3 to the downward rotation range of the roller 3, the portion of the rod that protrudes from the end of the roller 3 comes into contact with the upper end of the guide rod 8. .

The take-out device shown in the embodiment has the above structure.

Next, its effect will be explained.

Now, when a large number of bars A are placed on the conveyor belt 2 of the belt conveyor 1, these bars A.

It is conveyed in the direction of the arrow in FIG. 1 and stopped at the storage section 4 on the back of the roller 3.

When the center part of the bar material A stopped in the storage section 4 comes into contact with the whole of one suction part 5 of the roller 3, the bar material A is suction-supported by the suction force of the suction part 5, and the rod-shaped material A is attracted and supported by the suction force of the suction part 5, and Due to the rotation, the paper is conveyed toward the downward rotation range of the roller 3.

Here, the width of the suction part 5 formed on the outer periphery of the roller 3 = J
- The outer diameter of the bar A is smaller than the outer diameter of the bar A, and the overall adsorption force is slightly stronger than the weight of the bar, so some part of the bar A comes into contact with a part of the adsorption part 5. In the state where
This bar is not supported by suction, and even if a part of it is suctioned by the suction part 5 and lifted upward, it will fall down halfway through the process.

When the bar A, which is suction-supported by the suction unit 5, is conveyed to the downward rotation range of the roller 3, the upper end of the guide rod 8 arranged on both sides of this downward rotation range moves the bar A from the roller end. Since the protruding portion is received, the attraction of the bar A is released, and as a result, both ends of the bar A are supported by the guide rod 8 and move along the guide rod 8I. Therefore, by connecting the end of the guide rod 8 to the processing machine, it is possible to supply the rod-shaped object to the processing machine.

In the case of the embodiment, the roller 3 is arranged on the belt conveyor, but the roller 3 may be arranged above the plate extending horizontally from the end of the inclined bottom plate of the chute.
The mounting position of the roller is arbitrary, and FIG. 4 shows another embodiment of the roller according to the present invention.

The roller 3 has a hollow cylindrical shape, and the inside of the roller 3 is hollow.
The suction chamber 10 and the non-suction chamber 11 are partitioned by a fixed partition plate 9 that is not connected to the suction chamber 10 . In addition, there is a slit-shaped suction hole 1 extending in the axial direction on a part of the outer circumference of the roller.
2 is provided, and this suction hole 12 serves as the suction part 5.

Now, when a suction force is applied to the suction chamber 10 and the roller 3 is rotated, when the suction hole 12 rotates around the outer circumference of the suction chamber 10, the suction force is applied to the suction hole 12.
The bar A can be suction-supported by the roller 2, and by the rotation of the roller 3, this bar can be conveyed across the downward rotation range of the roller.

As described above, in the present invention, a suction part extending in the axial direction is provided on the outer periphery of a roller that is rotationally driven in one direction, and the width of this suction part is made smaller than the outer diameter of the bar to be conveyed. In addition, since the suction force of the entire suction section is slightly stronger than the weight of each bar, a plurality of rods loaded in the storage section can be suction-supported by one suction section, or be tilted relative to the suction section. It is possible to prevent it from being suction-supported. As a result, the rollers are rotated in the cutting direction (thus, the bars loaded randomly in the storage section can be reliably fed one by one and taken out in a parallel state.

In addition, by rotating the roller, the bars in the storage section can be rotated by contact rotation with the roller, so it is possible to release the entanglement of the bars stacked randomly, and the suction section (This can create a situation where it is easy to be attracted.
