The position of the steel material 9 is adjusted to be ON when the steel material 9 is accurately sandwiched between the fixed grip portion 7 and the movable grip portion 8.

As shown in FIGS. 2, 3 and 6, the rollers 14 are a first roller 17 and a second roller 1 having the same outer diameter.
8 and these are tilted to the left and right by the same tilt angle and are supported on the support base 21. The L-shaped shaped steel 9 is supported by the outer circumferences of the first roller 17 and the second roller 18 on the lower surfaces of both sides thereof. An escape portion 35 for preventing interference is formed on the second roller 18. The shaped steel 9 is clamped on one side by the fixed grip 7 and the movable grip 8. In this embodiment, the fixed gripping portion 7 engages in the escape portion 35 of the second roller 18, but they do not interfere with each other. Therefore, even if the shaped steel 9 is sandwiched between the fixed member 5 and the swinging member 6 and the transport base 2 is driven by the drive unit 3, the clamp mechanism unit 4 and the roller 14 do not interfere with each other.

Next, referring to FIG. 5, description will be made on an automatic conveying / piercing / cutting apparatus for steel products provided with the drive unit 3 and the clamp mechanism unit 4 of this embodiment. The transfer table 3 of the drive unit 3 is slidably supported on the base table 15. The clamp mechanism portion 4 is arranged by extending the fixing member 5 and the swinging member 6 along the conveying direction. As described above, the shaped steel 9 is sandwiched between the fixed gripping portion 7 and the moving gripping portion 8 of the fixed member 5 and the swinging member 6 which face each other. On the other hand, a plurality of rows of the first roller 17 and the second roller 18 having the escape portion 35 are placed on the base 15 and abuttingly engaged with the lower surfaces of both sides of the shaped steel 9 to make the shaped steel 9
Support. On the rear end side of the main body of the apparatus, there are arranged a fixing mechanism portion 36 for punching, which positions and fixes the shaped steel 9 at a predetermined punching position, punching machines 37, 38, a fixing mechanism portion 39 for cutting, a cutting device, a discharging mechanism portion and the like. It The shaped steel 9 whose rear end is gripped by the clamp mechanism portion 4 is transported while being supported by the rollers 14 and positioned and fixed at a predetermined position, then subjected to predetermined punching and cutting and conveyed to the next process side.

Next, the conveyance and clamping action of the shaped steel 9 by the drive unit 3 and the clamp mechanism unit 4 of this embodiment will be described in more detail. 2 and 4, the pressurizing cylinder 1
In the free state where the pressure medium is not introduced into 0, the swinging member 6 is rotated counterclockwise about the pin 32 by the spring force of the spring 11. Therefore, the space between the fixed grip portion 7 of the fixed member 5 and the movable grip portion 8 of the swing member 6 is held in a state of being opened wider than the plate thickness of the shaped steel 9. Shaped steel 9 base 15
When mounted on the roller 14, the driving motor 25 of the clamp mechanism section 4 starts to operate. As a result, the pinion gear 27 rotates. Since the pinion gear 27 meshes with the rack 19, the transport table 2 moves in the transport direction along the rack 19. The fixed grip portion 7 and the movable grip portion 8 of the fixed member 5 and the swing member 6 are engaged with one side of the shaped steel 9 from the rear surface side, and the rear end is sandwiched. When the pressure medium is introduced into the pressurizing cylinder 10, the push rod 30 presses the rocking member 6 to rotate the rocking member 6 in the clockwise direction about the pin 32. Therefore, one side of the shaped steel 9 is sandwiched between the fixed grip 7 and the movable grip 8.

In this state, the contact plate 33 fixed to the rocking member 6 comes into contact with the limit switch 34 to be turned on, and the shaped steel 9
It is confirmed that was confirmed. Pressure cylinder 1
When the gripping force of 0 satisfies a predetermined value, the detection unit 12 (FIG. 1) outputs a detection signal and the control unit 13 operates the drive motor 25 of the drive unit 3. Next, the drive motor 25
Is operated again, the entire clamp mechanism 4 moves, and the shaped steel 9 moves in the forward direction while being pressed from the rear. As described above, both the fixing member 5 and the swinging member 6 are provided on the tip end side of the cantilever support bracket 28, and are elongated along the carrying direction, so that the escape groove 3
By providing 5, etc., it is possible to proceed in the direction of the punching machines 37, 38 and the cutting device 40 without interfering with other parts.

As shown in FIG. 6, since the escape portion 35 for preventing interference is formed in the roller 14, the clamp mechanism portion 4 can clamp the position near the apex angle portion of the shaped steel 9, and The steel 9 is conveyed more stably. In the above description, the drive motor 25, the pinion gear 27, the rack 19 and the like are used as the drive unit. Instead, however, a nut-shaped member is provided on the carrier 2 and the feed screw shaft screwed to this is rotated by the rotating means. Alternatively, the carrier 2 may be moved. Alternatively, a piston of a pressing cylinder fixed to the immobile side of the apparatus at the base end side may be connected to the transfer table 2, and the transfer table 2 may be directly moved by the pressing cylinder. Further, in the above description, the fixing member 5 and the swinging member 6 have the illustrated shapes, but other shapes having no interference with other components may be used.

[0017]

According to the present invention, the following remarkable effects are obtained. 1) The clamp portion composed of a fixing member and a swinging member of the clamp mechanism means has a narrow and narrow width extending in the conveying direction of the steel material, and has a structure in which the upper and lower surfaces of the rear end of the steel material are clamped by its tip. In addition, since each component, for example, the relief portion is formed in the roller, the steel material is conveyed as it is to the final process side while being clamped by the clamp portion. Thereby, the transportation efficiency can be improved. 2) The steel member is securely gripped by the fixing member, the swinging member, the pressurizing unit, etc. of the clamp mechanism unit, and the drive unit is operated by the control unit when the pressing force reaches a predetermined value.
There is no slack in the clamp during the process, and stable and safe steel material transfer is possible. 3) Since the steel material is firmly held by holding the clamp portions that engage with the upper and lower surfaces of the steel material, the steel material can be used even if the thickness or shape of the steel material changes.
