Description of the Related Art Conventionally, as an apparatus for shaping and binding long products, as shown in Japanese Patent Application Laid-Open No. 3-51220 (steel pipe loading apparatus) shown in FIG. 5, an inclined table 41 and four sides of a hexagon are used. A long frame (steel pipe) is made up of a receiving frame 42 having a shaped shape and a guide frame 43 forming another side. The long material (steel pipe) is turned on the inclined table and put into the shaped frame formed by the receiving frame 42 and the guide frame 43. Loading devices are known.

[0003]

In the above-mentioned conventional apparatus, the turning speed of the long material is not always constant in the longitudinal direction. In the case of long members, there is a high possibility that the long members intersect within the frame and a good shaped shape cannot be obtained. Further, although the dimensions of the receiving frame are not described in detail, if the dimensions of the receiving frame are determined by merely geometrical dimensions, the long material with the protective material loaded with the protective material at the end may not be closely adhered in the receiving frame. It is not possible, and stable shaping and binding cannot be performed.

[0004] An object of the present invention is to provide a method in which a row of long materials conveyed into a shaping frame can be processed in a simple manner without crossing each other, and even with a long material with a protective material in which the long materials cannot adhere to each other. An object of the present invention is to provide a shaping and binding device capable of stably shaping by filling gaps between both sides generated during stacking, and a shaping method using the same.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, as a specific embodiment of the present invention, a description will be given of an example of an apparatus for shaping and binding a long steel pipe with a protective material having a protective material loaded at an end portion, with reference to the accompanying drawings. FIG. 1 is a perspective view showing the overall configuration of the shaping and binding apparatus of the present invention, and FIG. 2 is a cross-sectional view showing the details of a fixed frame and an opening / closing frame, the configuration of a transfer device, and the state of long materials stacked in the frame. FIG. 3 shows the structure and operation of a shaping apparatus using a segment that rises by using a pressing force when a long material to be transferred is lowered as another method of the opening / closing frame.

[0008] The configuration of the apparatus of the present invention will be described below with reference to FIGS. 1 and 2. The long material transfer operation of the present invention is performed by the following device configuration. That is, a receiving table 2 on which a number of long members 3 corresponding to one stage of a shaped shape are arranged, and the long members 3 are collectively picked up from the receiving table 2 and are moved up and down as means for transferring them into the shaping frame. Horizontally movable transfer device 4
Consisting of The long material 3 is a carriage 4 constituting the transfer device 4.
3 is attracted by using an electromagnet 41 suspended by an elevating rod 42 attached to the elevating and lowering via a rack and pinion mechanism 45. The carriage 43 travels horizontally on a traveling rail 46 by a chain drive 44, but can move up and down and travel with a positioning control function according to the diameter of the long material and the transfer position.

Next, the long material 3 transferred by the transfer device 4 is shaped into a predetermined shape in the shaping frame. The formatting frame is
Three rows of the in-side fixed frame 11 and the out-side fixed frame 12 forming the bottom side 13, the oblique side 14, and the side 15 of the shaped shape, and the input-side fixed frame 11 and the out-side which are located at the center of the three rows of fixed frames. Each of the fixed frames 12 is connected to each other by an L-shaped bracket 16 and can be opened and closed by driving the air cylinder 17, that is, is composed of an entrance-side opening / closing frame 51 and an exit-side opening / closing frame 52 that are mounted so as to project from the fixed frame. ing. Opening frame 5
The surfaces of the members 1 and 52 have an irregular shape that is continuous in the longitudinal direction so as to fill gaps on the sides corresponding to の of the long material diameter generated when the long materials are stacked.

In this embodiment, the receiving table 2 and the fixed frames 11 and 12 have a structure in which the long material is partially supported by two or three arms. However, the present invention is not limited to this. Avoids the failure of peripheral devices not shown,
It is desirable to increase the receiving area so that the long material does not bend. Further, the divided arm-shaped receiving table 2 and the fixed frames 11 and 12 may be movable in the longitudinal direction of the long material 3 so as to correspond to the length of the various long materials 3. In addition, since the transfer device 4 is a steel pipe as a target, an adsorption method using an electromagnet 41 is used. However, when a non-magnetic material is a target, a transfer device using a mechanical clamp mechanism can be considered.

The fixed frames 11 and 12 and the open / close frame 5 described above are used.
FIG. 2 shows details of the arrangement of 1, 52. In the 14-stage stacking and shaping in the example of the drawing, the entry side fixed frame 1 indicated by a black circle
1. The entrance-side open / close frame 51 and the exit-side open / close frame 52 each have five protrusions in order to strictly fix the ten long members on the side that respectively contact the exit-side fixing frame 12. These projections
It is opened and closed integrally by the cylinder 17, but it protrudes from the fixed frame so that A = 1/2 × D shown in FIG. 2 when the open / close frame is closed, and A <0 in the open state, that is, does not protrude from the fixed frame. Is stored. That is, the cylinder 17 is １ ／
It has an opening / closing stroke of × D or more. Here, D indicates the outer diameter of the long material. Further, the projection shape of the opening / closing frame is a trapezoidal shape which is easy to process in the drawing, but may be a semicircular shape having the same diameter as the long material.

FIG. 3 shows another embodiment of the open / close frame. This example has a configuration in which the rectangular segments 31 rotatably mounted on the fixed frame 12 at the rotation center 35 are arranged in the vertical direction by the number corresponding to the number of shaping steps.
The segment 31 has a weight at the corner 32, and when no external force is applied, the weight 32 is at the lower end and the fixed frame 1
The arrangement state shown in FIG. 3A in which the corner 33 protrudes from FIG. When the long members are sequentially transferred and the third stage indicated by a black circle is transferred, the lowermost segment 31 is provided at a position where the corner 33 is pressed down by the long member 3 and faces the weight 32. The trapezoidal projection 34 is fixed in a state of protruding from the fixing frame 12. This protrusion allowance A is A = 1/2 × similarly to FIG.
D. Subsequently, when the fourth-stage long material is transferred, the protrusion 34 forcibly transfers it to a position which is forcibly shifted by 1/2 × D from the lower long material.

The open / close frames 51 and 52 in FIG. 2, the sides 13, 14, and 15 of the fixed frame and the segment 31 in FIG.
Each of these parts is in contact with or rubs against a long material to be a product, and it is desirable to use a wear-resistant resin material for the purpose of preventing scratches on the product.

Next, the shaping operation in the apparatus shown in FIGS. 1 and 2 of the present invention will be described based on the operation flow of FIG.
In general, the long members 3 having the protection members 6 attached to the ends are stacked in such a manner that the protection members 6 are shifted from each other in the longitudinal direction of the long members 3 by more than the length of the protection members so that the protection members 6 do not overlap each other. (FIG. 4
(D)). For this reason, in the horizontal direction, the center-to-center distance between the long members becomes the protection member diameter SD, and in the vertical direction, the dimension is also indicated by X. X = (PD / 2) × √ (1 + 2SD / PD) △ H = SD-PD △ V = X-PD… where SD: protective material outer diameter PD: long material outer diameter

Therefore, in the cross section of the steel pipe portion, △
H, a gap of ΔV inevitably occurs in the vertical direction. In general,
At the time of shaping the long material 3, the fixed frame 11, 1, 1 at the center is used to prevent defective shaping such as the long material 3 falling into the gap.
The width of No. 2 is set smaller than the width of the fixed frame at both ends, and the gap is forcibly eliminated to adopt a drum-shaped shaping method (FIG. 4 (f)).
However, in this method, since the long material 3 is elastically deformed like a bow, a good shaped shape cannot be obtained unless the repulsive force is suppressed. In other words, it can be said that the drum-shaped shaping is difficult in the conventional method.

Therefore, in the shaping of the present embodiment, in the shaping up to the third stage, the open / close frames 51 and 52 are both open and stacked (FIG. 4).
(A)) Then, at the time of transfer of the fourth stage at which unevenness on the side begins, the entrance-side opening / closing frame 51 is closed and the exit-side opening / closing frame 52 is opened (FIG. 4B). The long material 3 is accurately transferred.
Further, at the time of transfer of the fifth stage, the delivery side opening / closing frame 5 is opposite to the fourth stage.
2 is closed, and the entrance side opening / closing frame 51 is opened (FIG. 4).
(C)) The fifth row of long members 3 is accurately transferred. In addition,
The transfer device 4 transfers the long material received from the receiving table 2 by the positioning control sequentially by 1/2 × SD so that the peaks and the valleys coincide with each other. Similarly, the opening and closing frames are alternately opened and closed in the same manner, and stacking without load collapse can be performed by accurate transfer.

Here, when transferring the fifth-stage long material,
The open / close frame, which was closed at the step, is temporarily opened so as not to hinder transfer (FIG. 4 (c)). The long material is stable and is unlikely to collapse, and even if collapse occurs due to the elastic force of the long material, it is closed again when the sixth stage is transferred (FIG. 4).
(B)), so that it is not pushed into the original position and disturbs the shaped shape.

The above operation is repeated, and the long material, which has been shaped into the schematic shape shown in FIG. 4 (f), is bound by a known binding means while maintaining the shaped shape, and is separated from the frame by a separately provided dispensing device or the like. Is discharged.

In the embodiment of the present invention, the example in which the gap at the center of the long material with the protective material is pressed is shown. However, the present invention is not limited to this example, and it is obvious that the shaping is effective for a steel pipe without the protective material. An apparatus is provided.

[0020]

As described above, according to the present invention, it is possible to eliminate the gap at the center of the steel pipe in the conventional apparatus, in the case of the long steel pipe with the protection material, in particular, the protection material is loaded at the end of the long material. This was the cause of the collapse of the load, and it was difficult to perform automatic shaping. It has a great effect.
