Reference numeral 17 denotes a cushioning material made of urethane rubber provided on the opposing surfaces of the support pieces 12 forming the storage recesses 15a to 15c. The steel material W falls and is stored in the storage recesses 15a to 15c. The steel material is not damaged when it is used. Lifters 20a, 20b, 20c are provided in storage recesses 15a to 15c.
Are installed by vertically inserting the cylindrical portions 21 at both ends of the base into guide poles 22. In FIG. 2, the lifters 20a ~
Although 20c appear to be connected to each other, as shown in FIG. 1, the phases are shifted in the left-right direction when viewed from the plane, and the individual lifters 20a to 20c can be operated separately.

The lifters 20a to 20c have transfer receiving portions 24 at their upper ends. In these transfer receiving portions, the solid line indicates the lower limit position and the chain line indicates the upper limit position in the drawing. 2 has a height substantially equal to that of the second half 2b of the support piece 12 so as to form an inclined surface flush with the transfer rail 13 of the support piece 12.
Is configured to be re-transportable. 26 is a lifter
The lifter is moved up and down by a drive motor using screw jacks 20a to 20c. Reference numeral 27 denotes a stopper for separating the steel material provided on the support piece 12 on the front side of the storage recesses 15a to 15c.

The second half 2b of the storage and transfer unit 2 has a first half 2a
A plurality of rails 31 are provided on the machine frame 32 and are arranged side by side at intervals in the transfer direction on the machine frame 32 so that the steel material W sent from the first half 2a can be provided. It is designed to be transported on the upper surface. Rail 31
A stopper 33 for temporarily stopping the conveyed steel material W is rotated by an operating member (not shown) so as to protrude upward from the rail 31. 35 is a piece of urethane rubber for buffering, 36 is the latter half 2 of the storage and transfer unit 2
An intermediate stopper provided adjacent to the discharge portion 3 at the distal end of the steel material W is movable in the left-right direction in FIG. 2 according to the diameter of the steel material W. Each book can be jumped up and sent to the discharge section 3 by a jumping member (not shown). With the above configuration, A, B, C, D and E in FIG. 2 are provided as storage zones for the steel material W.

The discharge section 3 has a plurality of transfer rollers 41 for receiving the steel materials W sent one by one from the storage transfer section 2 in the feed direction of the base 42 as described above.
Thus, the steel material is sent to the flaw detection equipment 43 installed on the other side.

The above operation will be described. As a work prior to the feeding of the steel material W from the discharge unit 3, a required number of steel materials W are stored in the storage and transfer unit 2. At this time, first, the stopper 36 is adjusted according to the diameter of the steel material W, and the lifters 20a to Receiving part 24 of 20c
Is set to the ascending limit position as shown by a chain line, the spring-out lever 8 is rotated. As a result, the steel materials W on the transfer roller 6 are repelled one by one by the repulsion lever 8 and transferred to the storage transfer unit 2 side. The transferred steel material W is stored in the transfer unit 2
Rail 13 and lifters 20a-20c of the first half 2a
Is slid by its own weight, and then slides on the rail 31 of the rear half 2b to come into contact with the stopper 36 and stop. At this time, in order to suppress the transfer speed of the steel material W, the stoppers 27 and 33 repeatedly receive the steel material W by repeatedly descending and rising (projecting) each time one steel material W is fed.

Hereinafter, the steel material W is similarly sent, and when the zone A is full of the steel material, the steel material W is sent to the zone B. At this time, the intermediate stopper 33 is turned upward and protruded.
When the space is also full, the screw jack 26 is driven, the lifter 20c is lowered, and the receiving portion 24 is lowered from the ascending limit position to a height slightly larger than the diameter of the steel material. At this time, the stopper 27 on the front side of the storage recess 15c rises and protrudes as shown to prevent the steel material from entering the B zone. The steel material sent by this is dropped and stored in the storage recess 15c, and when it is full by the lowering of the first stage, the receiving portion 24 is further lowered by one stage, and the lifter 20c is lowered while such an operation is repeated. Then, the operation is continued until the receiving portion 24 reaches the lower limit position or until the lot of the steel material W ends. Then, when the C zone is full of steel, the lifter 20b is lowered, and the stopper 27 on the front side of the storage recess 15b is raised and protruded to prevent the steel from entering the C zone. The steel material sent by this is dropped and stored in the storage recess 15b.
Further, when the D zone is full of steel, the lifter 20a is lowered, and the stopper 27 on the front side of the storage recess 15a is raised and protruded, so that the steel does not enter the D zone. The steel material sent by this is dropped and stored in the storage recess 15a. When the E zone is full of steel, the A
ＥE are all full.

After the full state, or in a state where the steel material W is stored in a required zone, the work of feeding the steel material from the discharge unit 3 is performed. Therefore, with respect to the foremost steel material stored in the zone A and in contact with the stopper 36, the steel material is first jumped up to the transfer roller 41 of the discharge unit 3 by the spring-out member and transferred. The transferred steel material is sent as it is to the flaw detection inspection device 43 in the longitudinal direction by the transfer roller 41 of the discharge unit 3. Then, every time one steel material is fed, the next steel material in contact with the stopper 36 is flipped up and transferred. Such work is performed continuously.

On the other hand, the steel material W
Is lost, the intermediate stopper 33 rotates downward, and the steel material in the B zone is sent to the A zone. When the steel material in the zone B runs out, the stopper 27 on the front side of the storage recess 15c is lowered, and the lifter 20c is raised.
The steel material in the zone is transferred from the receiving portion 24 of the lifter 20c through the transfer rail portion 13 of the support piece 12 to the rail of the rear half 2b of the storage transfer portion 2.
It is sent to 31 and sent to B zone. As a result, when the steel material in the C zone runs out, the stopper on the front side of the storage recess 15b is used.
27 is lowered, and the lifter 20b is raised, whereby the steel material in the D zone is transferred from the receiving portion 24 of the lifter 20b to the support piece.
After falling through the 12 transfer rails 13 into the storage recess 15c, it is stored and sent to the C zone. As a result, when the steel material in the D zone is exhausted, the stopper 27 on the front side of the storage recess 15a is lowered, and the lifter 20a is raised.
The steel material in the zone falls from the receiving portion 24 of the lifter 20a via the transfer rail portion 13 of the support piece 12 into the storage recess 15b and is stored therein.
Sent to D zone. In this way, during storage and transfer of the steel material in the storage and transfer unit 2, advance and advance are sequentially performed, and the transfer of the steel material W from the supply unit 1 to the discharge unit 3 is performed smoothly.

When it is necessary to continuously feed steel materials having different diameters, first confirm that the rear end of one of the steel materials exceeds the position of the intermediate stopper 33 and that all of them are in the A zone. The intermediate stopper 33 is pivoted upward so that the other steel material to be subsequently fed comes into contact with this stopper. As a result, the steel materials having different diameters are separated from each other with the intermediate stopper 33 as a boundary, and mixing of the other steel materials during transfer of one steel material in the A zone is prevented. And A
Intermediate stopper 33 after all processing of the steel material in the zone is completed.
Rotates downward, and the steel material in the B zone is sent to the A zone.

The above operations are all performed automatically under the control of a control device (not shown).

The above embodiment is a preferred example, and it goes without saying that the present invention may be embodied in other forms within the scope of the claims.
