Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sorting shelf in a pipe sorting device that stores pipe bodies such as temporary pipes used in construction work, sorting them according to their length.

PRIOR TECHNOLOGY As a pipe sorting device for storing pipe bodies such as temporary pipes by length, for example,
There is a structure shown in No. 60-14974. The sorting shelves installed in these pipe sorting devices are made up of a large number of racks placed one above the other at required intervals.Incoming pipes are stored in each rack according to size, and the pipes of the required size are stored in each rack. The body is removed using a lifting cradle.

Problems to be solved by the invention In this case, the length of the tubes supplied to the rack is not always constant, and tubes of various lengths and shorts are appropriately selected and supplied. The rack consists of a large number of skids arranged in parallel. Therefore, a long tube body is supported by three or more skids, but the tube bodies are not necessarily straight, and there are also tube bodies that are slightly curved (within an allowable range). Furthermore, it is difficult to arrange the top surfaces of a large number of skids exactly on the same plane. Therefore, when the elongated tube rolls and moves on the rack, its supporting location changes, and as a result, there is a risk that the running direction will be deviated and the tube may move obliquely to the skid.

Originally, it is preferable that pipes that are easily supplied be supplied with one end aligned, that is, positioned at a certain reference position, in order to align the ends when tying. The ends of each tube are uneven and there is a problem with bundling.

In view of this, the present invention aims to always roll in a good posture and prevent the running direction from going out of order.

Means for Solving the Problems The present invention for achieving the above object will be explained with reference to FIGS. 1 to 3, which correspond to embodiments. The tube sorting device 1 has a large number of racks 25, 25, .
It is equipped with a sorting shelf 4 consisting of...

Each rack 25 is formed from a large number of parallel skids 30a, 30b, 30c...
In addition, the reference side skid 30a located on the reference position A side of the pipe P to be supplied is installed higher than other skids 30b, 30c, etc. arranged in parallel at the same height so as to have a required step B. It is something.

Effect By mounting the reference side skid higher than the other skids, the supplied pipe body is always supported near both ends by two skids, regardless of its length, so that it can be transferred easily. The movement is good and the running direction does not go awry.

Embodiment In the figure, a pipe sorting device 1 includes a receiving mechanism 2 that receives pipes P to be carried in, a lift conveyor 3 that transports the pipes P supplied from the receiving mechanism 2 upward, and a lift conveyor 3 that Sorting shelf 4 that stores pipes P that can be lifted by length
Although not shown, it is equipped with a cradle for taking out tubes stored in a sorting shelf (Japanese Patent Application Laid-Open No. 60-14974).
(see No.) is attached.

The receiving mechanism 2 includes a roller conveyor 10 that receives the supplied tube P, a picker 11 that scoops up the tube P on the roller conveyor, and a picker 11 that scoops up the tube P that is on the roller conveyor.
The receiving skid 12 aligns the pipe bodies P supplied by the pipe body P, a reference position setting mechanism 13 for aligning the ends of the pipe bodies at reference positions to be described later, and a delivery mechanism 14 for the lift conveyor 3 are provided.

The reference position setting mechanism 13 sets one end of the pipe P in the pipe length measurement and sorting shelf 4 to a reference position A (FIG. 3).
For example, it is equipped with a pusher that presses the end of the tube, and the tube P to be supplied is
The ends are pushed out and aligned to a predetermined position. In the figure, 15 is a reference position setting mechanism 1 that pushes up the tube P on the skid 12.
This is a push-up table for sending out to the second skid 17 side of No. 3, and is raised and lowered by a cylinder 16.

The sending-out mechanism 14 includes a lifting platform 20 for pushing up the tube P sent out from the reference position setting mechanism 13, and a receiving table 21 on which the tube P pushed up by the lifting table 20 is placed and delivered to the lift conveyor 3. The table 20 is interlocked with the lift conveyor 3 via a link mechanism 22, and sequentially supplies the tubes P to a tube support bracket 23 attached to the lift conveyor 3.

A pipe length measuring means 24 is provided at a suitable location on the lift conveyor 3.
is in place. This pipe length measuring means, for example, arranges a large number of detection members such as optical sensors in the longitudinal direction of the pipe P being transported, measures the pipe length using the reference position as a reference, and stores it in a control circuit (not shown).

The sorting shelf 4 is made up of a large number of racks 25 arranged vertically in multiple stages with required intervals, and a rack 26 is provided oppositely to each rack on the entrance side. When the length-measured tube reaches a predetermined rack 25, the control circuit operates a kicker to move the tube P to the rack 25. Note that one end of each tube P is aligned at a reference position by the reference position setting mechanism 13, regardless of its length.

The rack 25 consists of a large number of parallel storage skids 30a, 30b, 30c, . . . (hereinafter collectively referred to as simply 30). The length of the tubes to be supplied is not necessarily constant, and a large number of tubes are provided in parallel in order to conveniently support tubes of any length. However, the long tube body is supported by three or more skids 30, which has the disadvantage that the rolling direction becomes unstable as described above. Therefore, in the present invention, regardless of the length of the tube body P, it is always supported by two skids, and the principle thereof is shown in FIG. However, the figure is a cross-sectional view taken along the line X--X in FIG. 3 and emphasizing the gist of the present invention.

That is, in the present invention, regardless of the length of the tube P, one end supporting the tube P, that is, the skid 30a on the side of the reference position A is used as a reference skid, and other supporting skids 30b and 30c arranged in parallel and having the same height are used as the reference skid. , 30d, and is mounted at a higher position with a step B.

As a result, the long pipe Pa is connected to two skids 3.
0a and 30b, the long tube Pb also does not come into contact with the central skids 30b and 30c, and only both ends of the tube are supported by the skids 30a and 30d, respectively. However, the step B is exaggerated in the diagram; in reality, even if the pipe P has some bending (within an allowable range), it should be as small as possible so as not to contact the intermediate skid. is preferred.

FIGS. 4 and 5 are explanatory diagrams of a presser plate provided on each skid 30 if necessary. This presser plate 3
1 is provided in order to prevent the pipe Pc from jumping up as shown by the chain line in FIG. 5, although it allows the pipe P to move between it and the lower skid 30. The distance from the skid can be adjusted freely.

Effects of the invention As described above, according to the present invention, the supplied pipe is supported at both ends regardless of its length, so the running direction of the pipe does not go awry when it rolls. There is no.

Therefore, when the ends of the tubes are aligned at a certain position and fed to the partition shelves, the ends are stored on each rack with the ends aligned, and there is no need to align the ends when bundling. have an effect.
