【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The cutting machine includes, for example, a band saw machine, a circular saw machine, and other various kinds of cutting machines. In this embodiment, a horizontal band saw machine will be described. Since this horizontal band saw machine has a known structure, the overall structure and detailed description thereof will be omitted. Further, as the product shape, there are shaped steel, flat steel, round bar, square bar and the like, but in the present embodiment, the description will be made on the round bar.

Referring to FIGS. 1, 2 and 3, a horizontal band saw machine 1 as a cutting machine is composed of a box-shaped base 3 and a cutting pad 5, and a cutting head 5 has a horizontal hinge pin 7. It is mounted so that it can be tilted freely. (See FIG. 3) A work table 9 on which a work W is placed is provided on the upper part of the base 3, and the work table 9 is orthogonal to the work table 9 on the feeding side of the band saw machine 1 (see FIGS. 1 and 2). On the left side, the work W is clamped and fixed on the left side in FIG. 3, which is the rear side orthogonal to the drawing, and a material feeding vise device 11 that is movable in the material feeding direction (left direction in FIG. 1) is provided.

The material feeding vise apparatus 11 is provided with a fixed vise jaw 11f and a movable vice jaw 11m capable of holding and fixing the work W. The movable vice jaw 11m is fixed to the fixed vice jaw 11f by a fluid pressure operated cylinder 13. The work W is clamped or unclamped in cooperation with each other. Further, the material feeding vice device 11 is provided so as to be movable in the material feeding direction by an appropriate driving means.

In the cutting head 5, a drive wheel 17 and a driven wheel 19 are rotatably mounted on a housing 15, and an endless band saw blade B is wound around the drive wheel 17 and the driven wheel 19. . Therefore, by driving the drive wheel 17, the band saw blade B is driven to travel to cut the work W. (See FIG. 3) Next, the front vise device 21, which is a part of the main part of this embodiment, will be described in detail.

The front vise device 21 is provided on the exit side of the horizontal band saw machine 1, that is, on the carry-out side of the product Ws, and the upper beam 25 of the pedestal 23 in the shape of a rectangular frame erected on the base 3. In addition, a plurality of support beams 27 for suspending the front vise device 21 are provided. A rail 29 is laid on the lower surface of the support beam 27 so as to extend in the material feeding direction, and a plurality of rails 29 are provided on the upper surface of a front vise main body 31 which is a member of the front vise device 21. Although not shown in the drawings, the front vise device 21 is provided so as to be movable in the material feeding direction by engaging with a sliding contact member such as an LM guide 33.

A fixed vise jaw 21 f and a movable vise jaw 21 m are suspended from the front vise body 31, and the fixed vise jaw 21 f is fixed to the front vise body 31. The movable vise jaw 21n is provided with a plurality of LM guides 37, which are slidable contact members, which slidably contact a plurality of rails 35 provided on the lower surface of the front vise body 31 so as to extend in a direction orthogonal to the material feeding direction. Is hung through.

The movable vise jaw 21 m is connected to a piston rod 41 of a fluid pressure operated cylinder 39 fixed to the front vise body 31.

With the above configuration, the front vise main body 31 is moved to the horizontal band saw machine 1 side by a driving means (not shown), and the work W as the product Ws is actuated by the cylinder 39 so that the fixed vise jaw 21f and the movable vise jaw 21m are moved. Clamps in cooperation with. Thereafter, a cutting operation is performed by the band saw blade B of the horizontal band saw machine 1, and when the product Ws is separated, the front vice main body 31 is moved to carry the product Ws to a predetermined fixed position.

The marking device 43 includes a marking head 45 and a marking head support portion 47 that supports the marking head 45.

The marking head 45 has a well-known configuration and a detailed description thereof will be omitted. As a marking method, a commonly used label method, ink jet method (dot print method), dot marking method, and engraving method are used. Any method can be used.

The marking head support portion 47 for supporting the marking head 45 is provided on a rail 49 laid on the base 3 in a direction orthogonal to the material feeding direction, and although not shown in the drawings, it may be driven by an appropriate driving means. The marking head support 47 can move forward and backward. Thus, the marking operation is performed by positioning the marking head 45 fixed to the marking head support portion 47 at a predetermined fixed position.

It should be noted that the marking position is not limited to one position on the end surface of the product Ws, but may be a plurality of positions. It is possible to mark on the upper surface near the end surface of the product Ws, for example, on the upper surface of the web near the cut surface in H steel or the like. It is possible.

As a storage box 51 for storing the product Ws delivered by the front vice device 21, for example, a drum can is mounted on a hand cart 53 and inserted directly below the product Ws and delivered. . Further, although the product Ws is carried out by the front vice device 21, the carrying-out position can be made constant by detection of a limit switch or the like although not shown.

With the above-described configuration, as its function, the work W placed on the work table 9 is clamped by the material feeding vise device 11 and positioned so as to project from the band saw blade B by a desired cutting length. . Then, the work W to be the product Ws is clamped by the front vise device 21, and the work W is cut by traveling the band saw blade B of the horizontal band saw machine 1.

The product Ws is carried out to a predetermined position by the front vice device 21, the working head 45 of the marking device 43 is moved to a predetermined position, and the end surface of the product Ws is marked.

When the marking is completed, the clamp of the front vise device 21 is opened to store the product Ws in the storage box 51, and when a predetermined amount of the product Ws is stored in the storage box 51, a handcart 53 is used to set a predetermined amount. Delivered to the place.

For this reason, since the marking device 43 and the front vise device 21 are provided on the base 3, the equipment can be made compact, and the product Ws after cutting is carried out by the front vise device 21 to a certain position. The end surface of the product Ws clamped by the front vice device 21 can be marked, so that the workability can be improved and the cost can be reduced.

It should be noted that the present invention is not limited to the above-described embodiment, but can be implemented in other modes by making appropriate changes. For example, in this embodiment, the front vice device 21 is moved to carry out the product Ws, but a roller conveyor system in which the rollers are rotated by the driving means is adopted, and when the product is carried out to the predetermined position by the roller conveyor, The product is clamped and marked with a vise device fixed in place. It is also possible to use a means to carry out the product on the roller conveyor after marking.

Further, the moving direction of the marking device 43 may be vertical direction or swinging, and the moving means may be a known means such as a cylinder, screw, rack and pinion system.
