Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to pipe body sorting 'J15fMt, which stores pipe bodies such as temporary pipes used in construction work by dividing them by length. Technology After the above temporary pipes are disassembled at the construction site,
The pipes are sorted by length and short and transported to the site, where they are inspected for pipe crushing, deformation, adhesion of concrete, etc., separated by length, stacked, bundled, and transported. . Conventionally, this work has been done visually and manually by the operator, but this is extremely inefficient, and in order to solve this problem, the present inventor first developed a device that automatically sorts and accumulates pipes. (Japanese Patent Application Laid-open No. 14974/1983).

Problems to be Solved by the Invention In order to attach a base plate or diode during temporary construction work, a pipe body with a pin a inserted at a position slightly deep from the end, as shown in Figure 13), is used. This is then mixed into a normal pipe and transported. In addition, as shown in the same figure (to), there are some that have clogging b of concrete and the like. These have the disadvantage that visual identification is time-consuming and, therefore, they are mixed and accumulated in ordinary tubes.

In view of this, the present invention aims to store tubes that are sent in by dividing them by length, detect the presence or absence of the bins and detect clogging, and prevent them from being mixed into normal tubes. .

Means for Solving the Problems The present invention for achieving the above objects will be explained based on the drawings corresponding to the embodiments.0 For pipe sorting, the device 1 receives and aligns the pipes P fed from the supply mechanism 2. Acceptance means 3

The skid 12 is formed by laying rails inclined at intervals, and the tube p rolls toward the positioning means 4 due to its own weight.

The receiving roller conveyor 10 is provided with a pair of sensors 13a for detecting the pipe body P being fed.

13b. The distance between the two sensors is set to the maximum length of the pipe to be accommodated, and the two sensors 13a are connected to a pipe of longer length that is mixed in and sent, that is, one pipe.

When 13b operates together, the kitsuka 11 does not operate,
The tube is sent out and discharged as it is.

The cutter 11 has an arm 15 attached to a drive shaft 14 that is rotated by a drive motor M1, and the drive motor M1 is activated at the moment when the rear end of the tube body P passes the front surface of the inlet side sensor 13a. Scoop up body P. The supply roller conveyor 6 of the supply mechanism 2 is operated intermittently so that the pipe P fed into the receiving means 3 is scooped up by the picker 11, and then the heated pipe is sent. Further, the receiving roller feed conveyor 10 is moved at high speed from the supply roller conveyor 6, and the tube bodies are connected 8+1-1, n. a second skid 21 that aligns and places the tubes P on the skid 21, a partition mechanism 22 that holds the tubes P on the skid 21 at predetermined intervals, and a pusher that presses each tube end held at a predetermined interval. 23.

The supply mechanism 20 includes a push-up table 24 on which the tube P transferred by its own weight from the skid 12 of the receiving means 3 is placed, and a push-up table 24.
The upper surface of the pressing platform is inclined toward the guide plate 27 as shown in the figure, and the tube body P is moved toward the second skid 21 when ascending. The partition mechanism 22 is the second
A plurality of tube bodies, for example three tube bodies, are held at intervals on the skid 21, and the first. Second. Third
The locking member 30.31.32 is provided. However, this number is determined to improve efficiency by processing a large number of tubes at the same time, and the number is determined arbitrarily.

As shown in FIG. 2, FIG. 6, and FIG.
4 protrudes above the skid 21 to lock the tubular body P, and when released, the locking claw 371 is rotated by the rotation cylinder 35. In this case, an extrusion claw 36 is attached to the locking claw,
The tubular body P is pushed out by the pushing claws 36.

The second and third locking members 31 and 32 have the same structure, and the second locking member 31 will be explained. This second locking member 3
1, a locking pawl 38 is pivotally supported on a swing shaft 37, and the swing shaft 3 is supported by a swing cylinder 39a.
7 moves back and forth, the locking pawl 38 is rotated about the fixed shaft 40 to lock or release the tubular body P.

In FIG. 1, 39b is a swing cylinder of the third engaging member 32. Also 41a, 41b. 41G is a sensor that detects the presence or absence of the tubular body P held by each of the engaging members 30, 31, and 32.

The pusher device is designed to press the rear ends of the three tubes P supported by each locking member 30, 31, 32 to a predetermined position, and includes a contact plate 42 that abuts the rear end of each tube P and , is provided with a pressing cylinder 43 that moves this contact plate 42 forward and backward. The material is a guide bar provided on a mounting base 45 to which the plate 42 is attached.

As will be described later, the end position of extrusion of the tube by the contact plate 42 is used as a measurement reference position for the tube length measuring means 73 provided in the storage means 5), and the ends of the supplied tubes are irregular. For this reason, it is preferable that the transition distance of the abutment plate 42 is a considerable length, and therefore the end locking members 30a, 31a of each of the above-mentioned locking members 30, 31, 32
, 32a are configured to allow movement of the contact plate 42.

As shown in FIGS. 9 and 10, the first bevel locking member 30a includes a rotating pawl 50 for locking the tube, a guide plate 51, and an abutment plate 52 facing the guide plate 51. Guide plate 5
1 is attached to a mounting base 45 of the press cylinder, and the rotating pawl 50 and the abutting plate 52 are connected by a support shaft &, and the abutting plate is provided with an abutting roller 8 that abuts against the guide plate 51. The guide plate 51 is formed with a relief surface 55a and a pressing surface 55b for the abutting roller holder, and normally the abutting roller lag does not come into contact with the guide plate 51, and the rotary claw 50 locks the tube body P. ,
When the pusher device is activated, the guide plate 51 moves forward, causing the abutting plate 52 and the rotating claw 50 to rotate (the position indicated by the chain line in FIG. 10).
The tubular body P allows the forward movement of the contact plate 42 and holds the rotary claw 50 in a rotated state by the pressing surface 55b of the guide plate 51 while the contact plate 42 is moving forward. Even if the engagement is disengaged, the insertion tube 8 can be attached to the contact plate 42 as described later.
1 and therefore will not migrate. As shown in FIGS. 5, 6, and 8, the second end locking member 31a is a supporting shaft that rotatably supports the board I which is supported by the swing shaft 37 and the upper part of the board. The base plate 56 and the base plate 57 are connected to each other by a spring 59, and the spring 59 allows the base plate 56 to connect the base plate 56 to the base plate 57.
6, the rotating arm and the back plate are maintained in a nearly straight line.

This rotating arm 58 is pressed and rotated by the advance of the abutment plate 42 of the pusher device, and as the spring 59 passes over the support shaft 57t, the rotating arm helmet rotates toward the support base 61 and presses against the support base. It is supported and allows the back and forth movement of the contact plate 42. By moving the swinging shaft 37 to the position indicated by the chain line in FIG. 56 and returns to the linear position. The sorting storage means 5 is shown in FIGS. 1 and 2.
As shown in the figure, the tube P fed from the positioning means 4
A supplying member 70 that supplies one by one, and this supplying member 70
A chain conveyor 71 for receiving and raising the tube body P supplied from the chain conveyor 71, a large number of racks 72, 72, . . . , and a tube length measuring means 73t are provided.

The supply member 70 includes a push-up table 74 and a crank mechanism 7 that rotates in synchronization with a chain conveyor 71 to raise and lower the push-up table.
5 and the chain conveyor 71 supporting the pushed-up pipe P
It consists of a pedestal 76 for delivering to. A tube support bracket 77 is attached to the chain conveyor 71, and an extrusion mechanism 78 for selecting the tube P conveyed by the chain conveyor 71 and pushing it into the rack 72 is provided opposite to the tick 72. The pipe length measuring means 73 includes sensors 73L, 73b, 73C, and 73L, 73b, 73C, and 73L, respectively, which are arranged at positions corresponding to lengths to be divided in advance, with the end of the pipe pushed out by the pusher as a reference.
...it becomes more. That is, although it is detected by the sensor 73b,
If the length does not reach sensor 73 C, sensor 73 b
The length corresponds to , and an activation signal is given to the extrusion mechanism 78 for the raster that accommodates this. Among the pipes to be stored, as shown in No. 131ffl (a), there is a pipe Pa to which a bin a is attached for attaching a base plate or joint during assembly, and as shown in the plow in the same figure, cement etc. There is also a pipe body pb which has clogging b.

The present invention detects this and distinguishes it from a normal pipe, and the pusher arm is equipped with a bottle detection means. This pin detection means (material) consists of an insertion tube 81 inserted into the tube body and a metal detection sensor 8 attached to the tip of the insertion tube.
2. The insertion tube 81 is slidably inserted into the abutting plate 42 and the mounting base 45, and a stopper M is provided on the pusher support cover opposite to the insertion tube 81.

In the above configuration, the tube P supplied from the supply 1 structure 2 and moving on the receiving roller conveyor 10 is detected by the entrance side sensor 13 a, and the tube end is detected by the sensor 13 a.
Immediately after passing through a, the kicker 11 is activated to scoop up the pipe P and transfer it onto the skid 12.

However, if a tubular body with an abnormal length is mixed in, the tip of the tubular body may pass through the outlet side sensor 13a before the end of the tubular body passes through the inlet side sensor 13a.
When the length b is reached, the 1st cutter 11 does not operate and the 1st part is sent out as it is, and the roller conveyor 6 is stopped for a period of time until the end of the abnormally long tube passes the exit side sensor 13b. The tubes on the skid 12 are sequentially moved onto the push-up table U by their own weight, and are transferred onto the second skid 21 by the push-up stand 24. In this case, although the locking pawl 34 of the first locking member 30 projects to the locking position, the locking claw 34 of the first locking member 30 projects to the second locking position. Third locking member 31.32
The locking claw 38 is in the retracted position. When one tube body is supported by the first locking member 30, the sensor 41
a detects this, moves the second locking member 31 to the locking position, simultaneously supplies the next tube body with the push-up table 24, and
It is supported by an engaging member 31. Next, the third
The third locking member 32 supports the tube body. When the tube body is supported by this third engaging member 32, the sensor 41
C detects this and operates the pusher 23. The pusher lever moves the contact plate 42 forward, aligns the rear ends of the three tubes, and moves to a predetermined position, that is, the measurement reference position A for the tube length measuring means 73. At the same time, the insertion tube 81 between the pin detection means is inserted into each tube internal bore.

In this case, it is inserted as is into the pipe body that does not have a bottle a, but the 12th
As shown in the figure), the insertion tube 81 is stopped from moving forward by the bin a, and is pushed into the contact plate 42 and the mounting base 45. At the same time, the metal detection sensor 82 detects the bin a'6. In addition, for a tube pb whose inner tube hole is clogged with foreign matter b, the insertion tube 81 is similarly pushed into the contact plate 42, etc., as shown in FIG. 8
2 does not work.

With these, the presence or absence of bottle a or clogging b can be determined using the insertion tube 81.
The amount of input and output is stored in a control mechanism (not shown).

Next, the contact plate 42 is moved back. At this time, when the insertion tube 81 is being pushed in by the bottle a or the like, the insertion tube 81 is pushed out by the stopper U as shown in FIG. 11, and returns to the initial waiting position where it protrudes a predetermined amount from the contact plate 42. As the pusher is completely retracted, each locking member 30, 31, 32 moves to the retracted position, the three pipes are sorted to the storage means 5 side, and the supply member 7o transfers the pipes one by one to the chain conveyor 7.
It is delivered to 1. While the pipe is being raised by the chain conveyor 71, the length of the pipe is detected by the pipe length measuring means, and a detection signal is applied to the control mechanism. The control mechanism determines the rack to be stored based on the presence or absence of the bottle or clogging and the pipe length, and when the pipe reaches the expected rack position, it operates the corresponding pushing mechanism 78 to move the pipe onto the rack 72. to move to.

Effects of the Invention As described above, according to the present invention, the pusher pushes one end of the irregular length tubes that are fed in sequentially to a predetermined position, and this position is used as the length measurement reference position, so that the pipe length can be reliably measured. In addition, since the pusher is designed to detect the presence or absence of clogging of the bottles installed in the pipe bodies and foreign objects, the pipe bodies stored in the racks are free from obstructions caused by the pipes with the bottles or foreign objects. This has the advantage that clogged pipes can be sorted and stored separately in each rack without being mixed in.
