Abstract

PURPOSE:To facilitate the accurate measurement of a dimension by providing a pipe length measuring member on a lift conveyor for conveying a pipe body relative to a rack for storing the pipe body and by measuring a pipe length. CONSTITUTION:One end of a pipe body P carried in is set to a reference position determined in advance by pipe body positioning means 13 and the pipe body P is delivered to a lift conveyor 3. The pipe body P raised by the lift conveyor 3 is detected by a pipe body detecting element 56 positioned so as to oppose the pipe body P and its length is judged as the length from the reference position to the farthest positioned detecting element among the elements which have detected the pipe body P. Thus, the pipe length is measured just before a rack is reached, enabling the measurement to be facilitated.

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to pipe length measurement using a pipe sorting device that separates and stores pipe bodies such as temporary pipes used in construction and investment work by length. Regarding the mechanism.

Prior art 7. For sorting pipes such as pipes for temporary submergence, there is an apparatus having a structure shown in, for example, Japanese Patent Application Laid-open No. 14974/1983. In this pipe sorting, the equipment is used to sort the pipes being carried in by
The tube is transported upward by a receiving lift conveyor, divided into tubes according to one dimension, and stored in multiple racks.As a means for measuring the dimensions of the tube, as shown in the above-mentioned known example, There is a method of measuring the amount of time it takes for a tube fed at a high speed to pass in front of a detection member.

Problems to be Solved by the Invention The above-mentioned measurement of the pipe length is carried out on the pipe receiving conveyor, but a large number of pipes are involved between measuring the pipe length and storing it in the rack, and one This may cause the order to be out of order due to the tubes climbing onto other tubes or a mistake in scooping up the tubes by the lift conveyor. If the order is out of order, different types of tube bodies will inevitably be mixed in.

Furthermore, the weight of the tube body varies depending on its length, and the frictional resistance against the receiving conveyor (for example, a roller conveyor) varies, causing slippage and the like, making it difficult to accurately measure the tube body.

In view of this, the object of the present invention is to measure the length of the pipe immediately before it reaches the rack, and to simplify the measurement.

During the ascent by the lift conveyor ys, the length of the tube body P is measured by the fuze length measuring member IsS. The measurement procedure will be explained below. One end of the tube P is at the reference position A as described above, so one end of the tube Hp is at the reference element rtg.
detected by a. Then, the other end is, for example, No. 9r4l.
ζ As shown, when it is detected by element SSC but not by element ggd, its length is equal to element S R@-B
It is stored in the control device as a tube with a length between II and c, and when this tube reaches the tube storage rack 4 with the corresponding length,
This; actuates the corresponding tube pushing member IIo and moves it onto the rack.

Similarly, a tube detected by element rtgd but not detected by element Figure is transferred to a predetermined rack by the same means as described above as a length between sga and i6d.

In addition, when the above-mentioned pin 1 is provided on the tubular body P, even if the pins have the same size, they are divided into 11 pins and stored in i racks.

In addition, when the tube P is pushed out by the pusher 2m, or when it moves past the reference position A due to some reason υ1, and its end is not detected by the reference element 5g1s, it is considered impossible to measure, for example, the top Transfer to rack.

Also, when transferring to the lift conveyor 3, a case may be considered in which the pipe P does not move horizontally to the support bracket (ill) of the lift conveyor 8, but is supported by a support bracket with a different role as shown by the chain line in Fig. 9, and rises. It will be done. Detection element 1
%6b is designed to detect this, and when the pipe P is carried out in a normal horizontal state, the detection element 511b operates at the same time as the reference element IIIg@, but as shown by the chain line above, the detection element 511b operates at the same time as the reference element IIIg@. When supported and raised, pixel element gga
, #Igb operation time is shifted. As a result, when it is known that the tube body has been picked up defectively and is stored in the control circuit, the IC lift conveyor is stopped and an alarm is issued, so that the operator removes the tube body that has been picked up defectively from the lift conveyor 8.

Effects of the Invention As described above, according to the present invention, a pipe length measuring member is arranged on the lift conveyor that transports the pipe bodies to the rack in which they are to be stored, and the pipe length is measured. Transfer or delivery operations performed before reaching Cζ do not cause such operations due to errors around the first transition stage, and storage operations performed in the control circuit are also simplified.

Furthermore, the pipe length measuring member has a large number of detection elements arranged at predetermined distances, and the length is determined by the distance 1 between the elements that detect the pipe body, so the measurement is extremely easy. It has an effect.
