DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding device for forming a tubular body such as a cylindrical steel pipe such as a pipe into a bundle having hexagonal side surfaces.

[0002]

2. Description of the Related Art In some cases, a large number of cylindrical steel pipes such as pipes need to be bundled together for the convenience of handling or storage in a warehouse or the like.
A binding method often used in such a case is to form a bundle having a hexagonal side surface as shown in FIG.

[0003] As a binding device for binding a plurality of pipes (hereinafter, referred to as "pipe") so that the side surfaces have a hexagonal shape, devices shown in Figs. 4 and 5 are known. This binding device includes a vertical wall surface 3a, a first bottom surface 3b disposed at an angle of 120 ° with the lower end of the wall surface 3a,
A forming frame 3 including a lower end of the bottom surface 3b and a second bottom surface 3c arranged at an angle of 120 °, and a transfer mechanism 2 including a chain conveyor for transferring the pipes 1 into the forming frame 3 one by one. It has.

[0004] In this conventional binding device, as shown in FIG.
11c and 11d are inserted into the forming frame 3 to form a first row of tubes, and then the forming frame 3 descends, and
The second row of pipes is formed in the order of 2b and thereafter, and the pipes 1 are sequentially stacked in a hexagonal shape (hereinafter, referred to as “forming”). Then, after the molding, binding is performed with a hoop or the like (hereinafter, referred to as “prior art 1”).

However, in the prior art 1, when a plurality of pipes are formed into a hexagon, the pipe 11a is shifted upward from a position to be stopped as shown in FIG.
There was a problem that it could not be formed into a clean hexagon (substantially regular hexagon) and collapsed. The cause of this deviation is that the molding frame 3
The pipe 12a moves from the transport mechanism 2 to the molding frame 3
Impact due to momentum when falling into the pipe 11
b, 11c and 11d. Such collapse of the position of the pipe tends to be more remarkable when the pipe diameter is small.

Conventionally, a plate 4 for fixing a pipe (hereinafter referred to as "corrugated plate" in the form of a plate) having a semicircular groove corresponding to the diameter of the pipe as shown in FIG. Bottom 3
b to prevent displacement of the pipe position (hereinafter referred to as "prior art 2").

[0007]

However, the corrugated sheet 4
Must be replaced every time the pipe diameter is different,
An operator is required for this replacement, and moreover, about 10 minutes are consumed for each replacement, which lowers the working rate. Further, the cost of the corrugated sheet itself has increased.

Moreover, even with the use of this corrugated sheet, there is a problem that the hexagonal molding may be broken in a heavy pipe. In such a case, the worker must cleanly reshape the broken pipe, which further lowers the working rate.

Accordingly, an object of the present invention is to provide a tube binding apparatus capable of efficiently forming a tube or the like into a bundle having hexagonal side surfaces without using a corrugated plate and without breaking a hexagonal shape. It is in.

[0010]

According to the present invention, there is provided a fuel cell system having a first wall disposed at an angle of 120 ° with a vertical wall surface and a lower end of the wall surface.
A forming frame including a bottom surface, a second bottom surface disposed at an angle of 120 ° with the lower end of the first bottom surface, a transfer mechanism for loading tubes one by one into the forming frame, and the forming frame and a stopper for suppressing the tube so as not to shift the lowermost tube charged by tube rows of each stage are sequentially aligned within the
Spring for shock absorption is attached to the stopper
In particular, it has features.

[0011]

When the pipes are loaded, the lowermost pipes of the rows of pipes which are loaded in the molding frame and are sequentially arranged are held down by stoppers, thereby preventing displacement due to dropping of the pipes. In addition, even when the tubes are continuously charged, the bundle can be formed into a bundle having a substantially regular hexagonal side without being deformed. Further, by moving the stopper at a desired optimum speed, the falling speed of the pipe can be controlled, and the displacement of the pipe from a predetermined position and the molding collapse can be prevented. In addition, the stopper
A spring for absorbing shock to cope with the shock applied when the tube falls is attached, and the displacement due to the impact of the tube falling when the tube is loaded can be prevented. Further, when the pipe diameters are different, it can be dealt with by changing the position of the transport mechanism. Therefore, the operator does not need to change the corrugated sheet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described based on embodiments shown in the drawings.

FIG. 1 is a side view showing an embodiment of the present invention. 2 and 3 are side views for explaining the movement of the pipe. As shown in FIGS. 1 to 3, the binding device of the present invention includes a vertical wall surface 3 a, a lower end of the vertical wall surface 3 a,
And a second bottom surface 3c disposed at an angle of 120 ° with the lower end of the first bottom surface 3b. It has a transport mechanism 2 and a stopper 5 for loading one by one. The forming frame 3 has a function as a dummy frame for forming a pipe into a hexagonal shape. The transport mechanism 2 comprises a chain conveyor, a belt conveyor, or the like. The upper end of the stopper 5 is pivotally mounted on a part of the transport mechanism 2, and the stopper 5 can suppress the pipe 1 toward the wall surface 3 b by the tensile force of the spring 6. The arrow 7 in FIG. 1 indicates the direction in which the pipe is inserted, and 8 indicates the direction in which the pipe moves.

The operation of the embodiment will be described. As shown in FIG. 2, in order to align the pipe on the first bottom surface 3b in the molding frame 3,
The pipes are successively charged by the transport mechanism, the pipes 1 are sequentially arranged at the lowermost stage, and the first row of pipes is formed obliquely. At this time, the stopper 5 waits at a position where the lowermost (first first) pipe 11a of the first row of pipes does not slip into the second bottom surface 3c, and holds the pipe 11 down. Further, the stopper 5 keeps holding the pipe 11a at the fixed position on the first bottom surface 3b by the insertion of the pipe 11b, thereby completing the first row of pipe rows. Then
As shown in FIG. 3 in which the pipes 12a and 12b of the second row are inserted, the lowermost pipe 12 of the second row of pipes is used.
The alignment is completed by suppressing a. In this manner, the lowermost pipes of the uppermost row of pipes are sequentially connected to the stoppers 5.
Thus, molding can be performed without any displacement. According to the present embodiment, a pipe bundle having a substantially hexagonal side surface as shown in FIG. 7 having a multi-stage row is formed.

The time difference between the prior art 2 of the related art and this embodiment is shown below. Bundling device of prior art 2: Corrugated plate replacement time: 10 minutes / times × 15 times / day = 150
Min / day Time to correct mold collapse; 3 minutes / times × 30 times / day = 90
Minutes / day Total: 240 minutes / day The binding device of the present embodiment: the above time is reduced.

Although this embodiment shows an example of a pipe, it goes without saying that a columnar body such as a round bar can be applied as a binding object.

[0017]

As described above, according to the present invention,
It can be formed automatically without reworking a tube bundle having substantially hexagonal side surfaces without causing molding collapse, and can be applied to a tube having a certain diameter. As described above, the work time consumed for changing and repairing the corrugated sheet, which is performed every time the pipe diameter is changed, is shortened, the work efficiency is greatly improved, and thus an industrially useful effect is brought about.
