Abstract

PURPOSE:To aim at the promotion of high efficiency for cutting work, by positioning and transferring the work supported on a supporting device by a clapper, while making up a cutting device so as to perform a pressed marking at a press unit installed in front of the supporting device. CONSTITUTION:A work material 2 of shape steel or the like placed on a work stocker is first dropped on a setting flap (unillustrated herein) in a state of being attractingly held through a magnet 9 by a work distributor crane 6, and transferred onto a supporting device 10b consisting of a roller via this flap. If so, then a work clapper 17b grasps the work and moves to some extent for positioning. Next, the work is cut off and subjected to other necessary working by a metal mold 21 and a hydraulic press 19 in combination, and after these operations are all over, each code number corresponding to a select command is marked by actuation of a marking device 24b. Then, the work 2 is transferred onto a product conveyor 15b and classified into two parts, namely, salable work and residual one.

The clappers 17a, 17b are moved along the lock screw shafts 16a, 161) by rotation of the clappers 17a, 17b. The clappers 17a and 17b have the function of holding and rotating the ends of the material. The ends of the material are gripped by the clappers 17a, 17bK.

The clappers 17a and 17b are moved and positioned by the movement of the clappers 17a and 17b.

A hydraulic press 19 is provided as a pressurizing means in front of the support devices 10a and 10b arranged in a straight line, and below it is a press mold table 2o, on which press molds 21 of different types are installed. be. The press mold table 2o can be driven and moved by a drive button (not shown) in a direction perpendicular to the material feeding direction, and a mold 21 suitable for the desired processing can be positioned at the location where the material is fed. It looks like this. The mold 21 is prepared for drilling, notching, and cutting. Note that one hydraulic press 19Fi may be provided for each line, but in this case, one hydraulic press 19 can be moved in a direction perpendicular to the material feed direction (lateral direction) using a hydraulic cylinder 22. , so that it can be applied to the left and right lines. In the figure, 23 is a clamp device for restraining the material;
Depending on the shape of the material, it plays an important role in preventing the material from shifting during cutting and ensuring cutting quality.

On the side or below the outlet of the hydraulic press 19, there is a marking device 24 for marking part numbers etc. on the processed material.
a, 24b force f is provided.

The marking devices 24a, 24b have a number of numbers incorporated therein, one of which is selected and marked on the material by movement of the n1 marking device.

On the exit side of the hydraulic press 19, linearly extending product conveyors 25a and 25b are installed on the extension of each line, respectively. At the inlet side ends of the product conveyors 25a, 25b (hydraulic press 19 side ends), there are provided material extraction devices 26a, 26b that grab and pull the material in the hydraulic press 19 and transfer it onto the product conveyors 25a, 25b. It is. The product conveyors 25a and 25b are mounted on a cutting table floating device 27, and their vertical positions can be changed by the operation of the device. This is a measure to make it compatible with the type of cutting blade used when cutting materials with the hydraulic press 19. Figure 5 (a) K
When a two-blade blade consisting of one upper blade 28 and one lower blade 29 is adopted as shown, the product conveyor 25a
, 25b are lowered by the thickness of the material 2, and K is set so as to prevent the material 2 from moving upward during cutting. When a three-blade (double cut method) consisting of one upper blade 28 and two lower blades 29, 29' is used as the cutting blade, as shown in FIG. 5(b), , it is assumed that the height of the material 2 and the height of the product conveyors 25a, 25b are the same.

1. A screw pallet 30 is provided below the manual side of the product conveyors 25a, 25b. The waste material that is no longer needed is not transferred to the product conveyors 25a and 25bK, but is dropped into the road material pallet 30 and carried out. On one side of the outside of the product conveyors 25a and 25b, there are recesses (fl, product pallets) 31a, 31b, respectively, in which products are sorted and organized in processing lot units. Also, a product conveyor 25a.

A leftover pallet 32 shared by both -17 bears 25a and 25b is provided on the inner side of 25b (7), and usable leftover materials are sorted and thrown here. Incidentally, the sorting of products and leftover materials is done by a device (not shown).

33Fi, a central controller performs numerical control (hereinafter referred to as NC) of a series of machining operations performed by this apparatus.

An example of the control is shown in FIG. 3, and the operation of the present apparatus will be explained below based on this figure. In addition, in the figure, 34 is a line controller, 35 is a material feeding and positioning controller,
36 press controller, 37 marking controller, 38 mold exchange controller, 3'llj: cutting pedestal floating and sinking controller,
40 is a component sorting and unloading controller. Although 41 is shown collectively, it is a drive source such as a motor or a cylinder for each device or mechanism, and each is controlled by the controllers 35 to 40. The IJ line controller 35 stores in advance a standard file 42 of machining turns and seams according to the shape to be machined.

NC machining information 43 corresponding to the machining dimensions, machining code, etc. of the material 2 supplied to the material stockers 4a, 4b is input to the line controller 34. Here, material stocker 4a
*4 The material on b should be symmetrical.

In the line controller 34, the modified turn and sequence that match the input information 43 are selected from the standard file 42, and based on this, control commands are input to each controller 35 to 40.
Ru.

First, the phase feed and positioning controller 35 is activated.
The material dispensing crane 6 is activated and the material 2 is placed on each of the material setting flaps 5a, 5b.Then, its drive, not shown, is activated and the materials 2 are placed on the material setting flaps 5a, 5b respectively.
, 5b are rotated as shown in FIG. 4(a), and the material 2 is dropped and transported. In addition, in the support device It)a, +Ob, the torque hinge 13 rotates, and the torque hinge 13 is rotated in advance as shown in FIG.
As shown in the figure, the material 2 receptacle is placed in the receiving state. Furthermore, one motor 18a and t8b are controlled and driven, and the material clapper 17
a and 17b grab the material 2 on the support devices LOa and IOb and move to position it.

Next, the press controller 36 controls the mold 21 and the hydraulic press 1.
9] Cutting or other processing of the material 2 is performed. If the mold 21 needs to be replaced, the press mold table 20 is moved in response to a command from the mold exchange controller 38 to replace it. At this time, the state of the material 2 is selected from the state shown in FIG. 4(a) or the state shown in FIG. 4(b) depending on the processing contents, the shape of the material 2, etc. Further, depending on the type of mold 21 (two-blade or three-blade) used during cutting, the cutting pedestal floating device 27 is activated by a command from the cutting pedestal floating/sinking controller 39, and the product conveyor 25
a and 25b are repositioned up and down.

After the processing is completed, the marking devices 24a and 24b are activated by the marking controller 37 to mark the material 2 with a number corresponding to the selection command.

Thereafter, the materials 2 transferred onto the product conveyors 25a and 2Sb are sorted into parts by the carry-out controller 40, and are separated into products and residual materials by the operation of the device, and are separated into product parts (31a, 31a and 2Sb, respectively). 31b.

The end pillar pallet) 30 is transferred or charged.

As described above, the material 2 supplied to each of the two lines is
If the two materials 2 are symmetrical, a series of processing of both materials 2 can be performed using a set of NC information. Further, it is also possible to perform NC processing using only one line.

As described above in detail based on one embodiment, n is one set.

High efficiency can be achieved by using NC information, simultaneous and additional air, B(2)''.
