At this time, the roller 65 of the lock lever 53 and the engagement member 63 provided on the X carriage 17 are disengaged, and the lock member 61 is engaged with the lock lever 53.

  Therefore, the entire weight of the clamp unit 29 is applied to the lock lever 53 via the lock member 61. Further, when the lower jaw 35 is lowered to the lower end by the cylinder 45, the compression spring 95 is bent. The upper portion of the locking member 43 abuts and engages with the locking portion 47k of the lock lever support member 47, so that the rise of the cylinder 45 is restricted.

  FIG. 10 is a view corresponding to FIG. 11 (c) showing the lowered end (clamped state) position in FIG. At this time, the lock member 61 is in the unlocked state in which the engagement with the lock lever 53 is released, and the piston rod 45b of the cylinder 45 is contracted to be in the clamped state at the lowered end position.

  At this time, the entire weight of the clamp unit 29 is applied to the compression spring 95, and the upper surface of the lower jaw 35 is b [mm slightly above the conveying level (pass line) PL due to the upward biasing force of the compression spring 95. ] (B = 5 in the embodiment).

  Next, the overall operation of the processed product carry-out device 5 and the positional relationship between the clamp units will be described in time series with reference to FIG.

(1) The clamp unit 29 “see FIG. 11A” with the lower jaw 35 positioned at the ascending end is moved and positioned to a position P3 which is a standby position on the processing machine side on the right side of the carry-out conveyor 11, and FIG. As shown in (b), the lower end of the lower jaw 35 of the clamp unit 29 is brought into the lower end unclamped state (A).

(2) Next, the position of the clampable end of the bent product W placed on the front table 3 of the bending machine 1 is the machine center C.I. The clamp unit 29 in the “lower end unclamped state” is moved toward the product W whose distance from L is within the clampable range of positions P1 to P2 (B).

  Note that the position P1 is a position where there is a clampable end of the left side of the minimum bent product size.

(3) The upper jaw 42 of the clamp unit 29 is lowered to clamp the product W (C), and the product W can be placed on the carry-out conveyor 11 in consideration of the length of the product W in the X-axis direction. Retract (D) to a proper position P4, place the clamp unit 29 in an unclamped state (see FIG. 11B) at this position P4 (E), and place the product W on the carry-out conveyor 11 Then, the vehicle moves backward from position P4 to position P5 slightly rearward (F).

(4) At the position P5, the lower jaw 35 is lifted to the rising end position (see FIG. 11A) (G) and then moved to the position P3 (H). While the clamp unit 29 is waiting, the product on the carry-out conveyor 11 is carried out for the next process by the operation of the carry-out conveyor 11, and the clamp unit 29 is in the initial state in the descending end unclamped state. Set to I (= A) and wait for the next step (H).

(5) After the step (4), the steps (1) to (5) are similarly repeated, and the processed folded products are sequentially carried out from the processing machine toward the next step.
