Abstract

PURPOSE:To ensure holding of a long material and to facilitate manufacture of various kinds of products in small quantities, by a method wherein the long material is firmly secured by means of two reference surfaces, crossing each other at right angles, a press block, and a press block mounted to a moving block. CONSTITUTION:When a long material A of an aluminum sash makes contact with a positioning mechanism 5, the other end of a chain 2 is lowered by means of a cylinder 2g. The sash material A is placed on the rollers of a conveyor 1, and a plate 5d is raised by means off a cylinder 5b. After a cylinder 5e and a press member 5f are situated in the same level as that of a block 5c, the sash material A is held between the nip formed by guide rollers 5g and 5h with the aid of the cylinder 5e. Thereafter, a press plate 3f of the upper part of a body 3c is brought into contact with the rear end surface of the sash material A to convey the sash material A in the direction of a work table. When the sash material A approaches a plate 21, after the body 3c is stopped, the press plate 3f is moved forward to press the tip of the sash material A against the plate 21. A press block is vertically moved for regulation, and the sash material A is secured between protecting members.

16d, and in a state where the positioning plate 21 is projected onto the transport path of the aluminum sash material A by the cylinder 19, the motor 3d of the workpiece feeding device 3 is driven to rotate the feed screw shaft 3a. By skipping, the feed main body 3C screwed onto the feed screw shaft 3a,
It is moved in the direction of the work table 6 while being guided and supported by a pair of guide shafts 3b. As a result, the press plate 3f installed on the upper part of the feed main body 3C via the cylinder 30 comes into contact with the rear end surface of the aluminum sash material A, and the aluminum sash material A is transferred toward the work table 6. In this case, the aluminum sash material A is attached to each guide roller 5Q, 5h of the workpiece positioning mechanism 5.
When the pressing plate 3f approaches each workpiece positioning mechanism 5, the reference block 5C and the pressing member 5f are lowered by the lifting cylinders 5a and 5b.

After the tip of the aluminum sash material A is transferred to the cutting 126 installation position, the cylinder 20 is operated to support the lower surface and one side surface of the aluminum sash material A with the steady rest member 22. Then, cut R
The circular saw blade 26b is rotated by the rotation motor 26a of No. 26, and the circular saw blade 26b is projected into the conveyance path for the aluminum sash material by the feeding motor 26C to cut the tip of the aluminum sash material. On the other hand, the feed main body 3c of the work feed device 3 is returned to its original position (the left end in FIGS. 5 and 7) by driving the motor 3d.

Next, by retreating the positioning plate 21 and the steady rest member 22 using each cylinder 19.20, and operating the upper and lower cylinders lQa, 10a and horizontal cylinder 118.11a of each pressing mechanism 1o, ii of the fixed chuck 8. , pressing block 10d and pressing piece 1
After releasing the fixed state of the aluminum sash IJA by 6, the chuck body 7C of the movable chuck 7 is moved forward along the ball screw shaft 7a and each guide member 7b by the motor 7d, thereby fixing the tip of the aluminum sash I4A. It is made to protrude from the opening B of the fixed chuck 9. Then, the aluminum sash material Δ is fixed by both pressing mechanisms 10.11 of each fixed chuck 8.9, and the moving chuck i?
The fixation of the aluminum sash material A by the chuck 7 is released, and the movable chuck 7 is returned to the carrying-in conveyor 1 side. At the same time, the movable table 6d of the workbench 6 is transferred to the carry-in conveyor 1 side, and each fixed chip 178 on the movable table 6b is moved.

A is processed by each processing machine 25 while being transferred forward as appropriate.

Next, when processing of the predetermined length of the aluminum sash material A (corresponding to the length of one product) is completed, the moving table 6b
is transferred to the cutting position 126, and the aluminum sash material A is cut by the circular saw blade 26b of the cutting machine 26 to produce one product. The produced product is placed on the transport row 530b of the carry-out conveyor 30 and transported, while the moving table 6b is returned to the processing machine 25 side, and the remaining aluminum sash material is removed in the same manner as described above. Start processing.

In this way, after processing the long aluminum sash material A, a large number of products obtained by cutting into predetermined lengths are placed on the conveyance roller 30b of the carry-out conveyor 30. The swinger attached to the piston rod of the cylinder 31 moves the plate 35 forward, thereby pushing out the product onto the product mounting table 33. In addition, the remaining aluminum sash material A after taking out a large number of products is also transferred to the carry-out conveyor 30.
After being sent upward, the plate 35 is moved back to push out the above-mentioned portion onto the mounting table 34 for remaining materials.

Although the present embodiment has been explained using aluminum sash material, it can also be applied to extrusion of non-ferrous metals such as copper or steel, processing and cutting of molded materials.
