Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacking device for bundling bars, which stacks a predetermined number of long bars, polygons, pipes and the like in accordance with a predetermined number of bars.

[0002]

2. Description of the Related Art When a long rod is shipped as a product, a predetermined number of rods corresponding to the rod diameter are stacked in a well-balanced state, and they are bundled in that state before being shipped. That is, for example, as shown in FIGS. 13 to 15, a predetermined number of rods for each diameter are stacked and stacked in that state. And, as a mode of stacking, it is required to bundle in a plurality of stages so that the cross section has a honeycomb-shaped circular or polygonal outer shape.

In order to bind the rods in this manner, the rods for one bundle are first taken out and aligned in one row, and then the rods are collected and stacked. For example, as shown in FIG. 16, the round bar 81 secured to the tilting skid 91 causes the tilting skid 91 to be tilted in the direction of the arrow to cause the stopper 91 to move.
After being brought to the side where there is one, the kicker 912 counts the number of one bundle and sends it to the stacking section 92, where it is dropped into the narrow attachment 94 for stacking.

That is, the bar material supplied to the stacking section 92 is
First, the lining rolls 95 for aligning the end faces are placed in a horizontal row, and then the collecting device 93 equipped with the attachment 94 at the upper part is lifted as shown by the chain line in the same figure, and is circled in the attachment 94. The rod 81 is collected. That is, the upper end surface 931 of the gathering device 93 is inclined from both sides toward the central attachment 94 side, and the round bar 81
Rolls into the attachment 94. Then, the round bars 81 are stacked according to the shape of the cross section of the attachment 84. In the figure, reference numeral 96 is a collecting device 93.
Reference numeral 951 is a stopper for regulating the mounting position of the round bar 81 on the aligning roll 95.

Further, as another example, Japanese Patent Laid-Open No. 57-771.
No. 22, the fixed horizontal roll 971, the fixed roll 972, and the movable roll 97 are shown in FIG.
Inside the hexagonal molding frame A consisting of 3,974, the inclined leaf 9
A stacking device 90 for stacking the round bars 81 placed on 8 has been proposed. That is, the inclined leaf 98 has one round bar 81
Is placed, the tilted leaf 98 is lowered, and then the left side of the paper is pulled out as shown in the lower tilted leaf 98 in the figure, and the round bars 81 are stacked one by one. Then, according to the size of the round bar 81, the number of bindings, the binding shape, etc., the movable roll 97
Set the position of 3,974.

[0006]

However, the above-mentioned conventional stacking device for binding rods has the following problems. First, the first problem of the first stacking apparatus shown in FIG.
Is an attachment 94 depending on the size and number of round bars 81.
Since it is necessary to replace the attachment 94, the number of types of attachments 94 increases, and it takes a lot of time to replace them.

A second problem is that when the collecting device 93 is raised and the round bar 81 is dropped into the attachment 94, the stacking shape may not be a predetermined stacking shape.
For example, the round bar 81 dropped in the attachment 94
There is a case where it becomes irritated. Here, the twill is a round bar 8
1 means that it is not aligned parallel to the longitudinal direction. That is, about 5 to 10 round bars 81 are attached to the attachment 9
When it is dropped into 4, it may not be stacked in a proper shape as shown in FIGS. 13 to 14.

On the other hand, the first problem with the second stacking device of FIG. 17 shown in Japanese Patent Application Laid-Open No. 57-77122 is that the movable rolls 973 and 974 of the hexagonal molding frame A function as stoppers. Since the position of the round bar 81 at the top (the right end on the paper surface) is determined, the degree of freedom in the stacking shape is limited. For example, when the number of rods on the uppermost stage is small and the number is odd, the leading round rod 81 is moved to the movable rolls 973, 974.
Since it abuts on the movable roll 9 and stops,
The arrangement is offset to the side of 73, 974.

The second problem is that since there is only one fixed roll 972 and there is no roll facing the movable roll 973 (that is, one side forming the side portion of the hexagon is missing), the stack is piled up. There is a risk that the round bar 81 will fall out of the frame. The third problem is that the round bar placed on the inclined leaf 98 rolls on the inclination and comes into contact with the movable rolls 973 and 974 as a stopper to stop.
At this time, the round bar 81 for one step placed on the inclined leaf 98
Are pressed against each other, resulting in pressure marks and abrasions.

The present invention has been made in view of the above-mentioned conventional problems, and is an efficient rod which can be used universally regardless of the number of rods, the diameter of the rods, and the shape of the binding. It is intended to provide a stacking device for binding materials.

[0011]
