Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a stacked hexagonal forming device used to bind long materials such as pipes, round bars, square bars, etc. into hexagonal shapes.

[Prior art and its problems]

Conventionally, long materials (hereinafter abbreviated as "materials")
As a hexagonal forming device, for example, JP-A No. 54-4977, JP-A-56-151628, and Utility Model Application No. 57-25834 are used.
Various devices have been proposed, such as those disclosed in Japanese Patent Application Laid-Open No. 58-82820, but all of these conventional devices have advantages and disadvantages, and none of them is satisfactory. In particular, when using a device that simultaneously feeds multiple pieces of material into a molding frame as one lot, the front and back materials may become uneven in the longitudinal direction or overlap in a criss-cross pattern, leading to feeding irregularities and material defects. There is a problem that the bundling may cause problems such as the bundling and the appearance of the bundle becomes poor, and there is also the problem that the forming position of the material within the forming frame moves depending on the size of the bundle.

[Purpose of invention and technical means]

The present invention has been made for the purpose of providing a stacked hexagonal forming apparatus for long materials that solves the above-mentioned problems, and employs the following technical means.

That is, it comprises a fixed inclined skid for transferring the material, a moving skid arranged in parallel with the fixed inclined skid for transferring the material further downstream, and a forming frame arranged downstream of the moving skid. In a hexagonal forming apparatus, a driving roller is disposed at a downstream position of a fixed inclined skid so as to be perpendicular to the fixed inclined skid and can be moved up and down in order to align the longitudinal position of the materials, and is capable of aligning a plurality of the materials with respect to one end. an aligning device integrally connected to the moving skid so as to be positioned with a predetermined gap above the downstream end of the moving skid through which the material ends pass to even out cross-stacking of material; arranged,
a leveling member whose lower surface can level the material and adjust the size of the gap in an open state in the upstream and downstream directions; and a lower oblique side on the upstream side of the forming frame to maintain a constant reference position during hexagonal forming of the material. A frame body that replaces the frame is equipped so that it can move forward and backward in the upstream and downstream directions with respect to the molding frame, and an endless belt is rotatably installed around the outer periphery of the frame body, and the back surface of the frame body is equipped with a group of idle receiving rollers. The gist of the present invention is to include an upstream lower oblique side frame constituted by a non-driven rotary belt frame supported by a rotary belt frame.

[Effect]

In the device according to the invention, the material flows as follows.

First, the materials are sorted by a rotary picker or the like into the number corresponding to the number of laminated layers and transferred onto a fixed inclined skid, where they are once stopped by a downstream stopper in the downstream area of this fixed inclined skid, and here The aligning device located at the site is raised to release the material from the upper surface of the inclined fixed skid, and in this state, the aligning roller is rotated to bring the material into contact with the aligning stopper, thereby separating the material from the longitudinal direction of the material. Adjust the direction position. Next, when the downstream stopper (the stopper provided at the position where the aligning device is located) is lowered and the aligning device is lowered, the material is fed to the position where the forming frame is located by the moving skid. A leveling member installed downstream of the moving skid ensures that the material is layered into a single layer and reaches the forming frame, and as the moving skid retreats, it falls from the tip (downstream end) of the moving skid into the forming frame. Steps are formed. Next, prior to the second stage forming, the bottom frame, downstream lower oblique frame, and upstream lower oblique frame of the forming frame are lowered by a predetermined amount, and thus the second stage, third stage, etc. are stacked, and the desired shape is formed. Once the hexagonal shape is obtained, binding is performed using a binding machine (not shown) or manually.

Reference numeral 12e denotes an upstream upper oblique side frame forming the upper upstream side of the hexagon, and like the rotating belt frame 12d, it is attached to a horizontally movable moving shaft 27 (see FIG. 7).

However, if the material A has a medium diameter size (20φ) or more, the upstream upper hypotenuse frame 12e hardly collapses according to the experience of the inventors, so it may be omitted. can.

The apparatus of the above embodiment is driven as follows.

First, the material A transferred on the entrance side inclined skid 1 is sorted by the rotary picker 2 by the number of materials forming the lowest stage (first stage) and sent onto the fixed inclined skid 3. The fed material A is temporarily stopped at the upstream stopper 4. That is, the material A is n before the upstream stopper 4.
When the number of books (the number of books at the bottom) are lined up, the upstream stopper 4 is lowered to transfer the material A further downstream, and the downstream stopper 5 stops the material A again. Therefore, the material A is the downstream stopper 5.
At the time of being sent to the aligning roller 11
A is sunk below the material A transfer line.

When the material A reaches the downstream stopper 5, in other words, when the alignment is ready, the aligning roller 11a is raised and the material A
is released from the fixed inclined skid 3 (see Fig. 7A), and at this point the aligning roller 11
A is rotated in the raised position, the material A is moved to the right in FIG. 1, and the ends of the material A are brought into contact with the aligning stopper 11b, thereby aligning n ends of the material A at the same time. Once the edge of the material A has been adjusted in this way, the rotation of the aligning roller 11a is stopped, and the aligning roller 11a and the downstream stopper 5 are
Submerge it below the transfer line. By this operation, the material A with its edges aligned is transferred onto the fixed inclined skid 3 again, and the material A is again rolled downstream on the fixed inclined skid 3 and then on the moving skid 6, and It is made even more layered by the leveling member 28 present in the section and reaches the forming frame.

In addition, in FIG. 7, the aligning roller 11a
The upstream stopper 4 is raised when the
(Number of rows) Shows the number of rows arranged in front of the upstream stopper 4.

Next, the movements of the moving skid 6 and the forming frame 12 will be explained according to the flow of the material A.

First, the moving skid 6 is placed on standby at the forward limit. The upper end of the rotating belt frame 12d and the lower end of the upstream upper oblique frame 12e are set to match the bottom height of the downstream end of the moving skid 6, and the rotating belt frame 12d corresponds to the desired hexagonal shape. The upstream upper hypotenuse frame 12e is made to stand by at an arbitrary position upstream of the rotating belt frame 12d. The bottom frame 12a and the downstream lower oblique frame 12b integrated therewith are connected to the chain 15.
The bottom frame 12a is rotated and pulled up obliquely, and the top surface of the bottom frame 12a is set at a height that corresponds to the position of the bottom surface of the downstream end of the moving skid 6. Of course, the protruding position of the downstream upper hypotenuse frame 12c relative to the downstream lower hypotenuse frame 12b is adjusted in accordance with the desired hexagonal size (see FIG. 7A).

Therefore, the first layer of material A that has fallen onto the moving skid 6 toward the downstream side is transferred to the downstream lower oblique frame 12b.
The moving skid 6 is then moved back upstream by the rotation of the drive gear 9, and the material A is transferred from above the moving skid 6 to the bottom frame 12.
It falls down onto a (Fig. 7c), and the bottom frame 12
The first stage is formed on a.

Of course, during the first stage molding, the downstream stopper 5 is raised again (FIG. 7C), and the second stage material A is stopped by the downstream stopper 5.

In this way, all n pieces of material A in the first stage are placed in the bottom frame 1.
2a, the chain 15 is rotated to lower the bottom frame 12a by approximately the outer diameter of the material A (FIG. 7D).

During this descent, the material A existing on the most upstream side on the bottom frame 12a is rubbed by the rotating belt frame 12d, but the belt 26 of the rotating belt frame 12d is
is rotated following the material A, and does not give large frictional resistance to the material A.

Then, the movable skid 6 is advanced downstream to the forward limit again (FIG. 7(e)), and the waiting material A of the second stage is fed with the ends aligned, and the above-mentioned operation is repeated until the middle stage is reached.

After passing the middle stage, the number of pieces of material A to be transferred decreases to a predetermined number. Therefore, in the stacking operation from the middle stage onwards, at the same time as the loading of the material A is finished and the bottom frame 12a is lowered, the upstream upper hypotenuse forming frame 12e is advanced downstream by the outer diameter of the material A, and then the moving skid Operate to advance 6.

In this way, once the hexagonal forming of a large number of material A has been completed, the bundle is temporarily bound, the bottom frame 12a is further lowered, and the bottom frame 12a is lowered to be carried out on a carry-out roller (not shown). 2 by raising the frame 12a and advancing the moving skid 6.
Enter the first operation.

〔effect〕

As explained above, the present invention has a structure in which the pipe ends are aligned during the material transfer process, followed by leveling feeding, and hexagonal forming of the material can always be performed on the downstream side of the forming frame. The material is arranged in the longitudinal direction and the stacking direction, making it possible to smoothly supply the material to the bottom frame.Moreover, since the material is hexagonally formed in a fixed position, temporary binding is extremely easy, which naturally reduces the occurrence of material defects. It also has the advantage of improving the bundling appearance, and is extremely effective and suitable as a stacked hexagonal forming device for materials.
