Description

[Detailed description of the invention] This invention relates to press working equipment such as press brakes, and more specifically, it is possible to sequentially and continuously perform different press workings on one material with one press brake. The present invention relates to a press processing apparatus including a plurality of processing stations.

BACKGROUND ART Conventionally, for example, when bending a box of a small item, a press brake is sometimes used. In this case, for example, if the front and rear dimensions of the box body are different from the left and right dimensions, or if the box body is punched in advance, multiple press processes are required, and a press may be provided for each process. , or the mold needed to be replaced.

Therefore, in the past, there were problems in that equipment costs increased and setup time was required to replace the mold, making it difficult to improve work efficiency.

This idea was made in view of the conventional problems as mentioned above, and it is equipped with multiple molds for different processing on one press brake.
Equipped with an industrial robot that can move left and right,
By combining a plurality of processing stations configured to be able to freely supply materials to a plurality of molds according to the order of processing, the efficiency of high-mix, low-volume production is improved.

Hereinafter, specific examples will be described in detail using the drawings.

Fig. 1 shows a press brake 3 with three types of upper molds 1a, 1b, 1c and lower molds 1d, 1e, 1f, with a rail 5 serving as a guide section provided in front of the press brake 3, and a material supported on the rail 5. A reference example of a press working device 9 consisting of one working station provided with a device 7 is shown. The first molds 1a, 1d, the second molds 1b, 1e, and the third molds 1c, 1f perform first, second, and third bending operations, respectively.

The material support device 7 is made of a general industrial robot and has similar functions, including a main shaft 11 that can move up and down, a pivot shaft 13 that can rotate, an extendable arm 15, and a rotatable arm. The material gripping part 17 is reciprocated from side to side on the rail 5 by a servo drive motor M.

In FIG. 1, a material support device 7 receives material from a material supply table (not shown), supplies the material to the first mold, and provides support during processing.
Next, it moves slightly to the left on the rail 5 to perform supply and support services to the second mold, and then moves to the left again to perform supply and support services to the third mold. At this time, the operation of the press brake 3, the material support device 7
Needless to say, the supply and support operations, movement operations on the rails, etc. can all be operated by the numerical controller NC.

The press working device 9 with the above configuration has one material support device that corresponds to three mold processes, and this material support device can be of a relatively simple configuration, and is capable of multiple processing in order to improve overall efficiency. can be dealt with. Although FIG. 1 shows an example of a plurality of machining areas by attaching three molds to a press brake, the same applies to work areas such as punching, drilling, drawing, etc. in a press machine.

FIG. 2 shows an example of a press processing apparatus in which a plurality of processing stations are arranged. The material processing apparatus is shown for press brakes 3a and 3b equipped with three molds. A material supply table 21 is placed on the right side of the base 19 in one processing station, a turntable 23 for rotating the product is placed in an intermediate position between each processing station, and a product receiving table is placed on the left side of the base 19 in the other processing station. Tables 25 are respectively provided, and material support devices 7a and 7b for each processing station are provided on the rails 5, respectively.

In FIG. 2, the material support device 7a receives the material from the material supply table 21 and provides a supply support service to the material processing device 3a. When the material support device 7a is providing support service for the material processing device 3a, the material support device 7b can cooperate if there is a need for regripping or the like. The material support device 7a places the material processed by the three molds on the turntable 23, and transfers the material to the material support device 7b. The material support device 7b that receives the material from the turntable 23 supplies and supports the material processing device 3b, and flows the processed product onto the product holder 25.

The press processing apparatus 9 having the above configuration processes six work areas using two material support devices. In addition, as described above, both material support devices can work together in operations such as regripping, allowing efficient operations to be carried out.

Figure 3 shows a plurality of material processing devices 3c, 3d, 3e.
This shows a reference example in which a plurality of guide paths 5a and 5b are provided in front of the guide path, a first material support device 7c is provided in the first guide path 5a, and a second material support device 7d is provided in the second guide path 5b. be. Material processing equipment includes various machine tools, assembly machines, and other material processing equipment. The first material support device 7c is of similar construction to that in the previous example. The second material support device 7d is
It may be an auxiliary or simple type that has the same or lower function than the material support device. On the right side of this press processing device is a lifter 2 on which the material W is placed.
7, a supply device 29 for suctioning and conveying the material W on the lifter, and a delivery positioning table 31 for positioning the material from the supply device to the material support device. Further, on the left side of the press processing apparatus, there are located a carry-out conveyor 33 for carrying out finished products, and a box 34 for receiving the products from the carry-out conveyor. Note that a tool rack 37 is shown on the base 19.

In FIG. 3, molds and the like are appropriately supplied from a tool rack 37 to a material processing apparatus that requires molds and the like. The first material support device 7c receives the material from the positioning table 31, and the second material support device 7c appropriately receives the material from the positioning table 31.
You can receive auxiliary services of d. The two material support devices can then work together in re-grabbing materials, alternating operations, and the like. In particular, when regripping, it is possible to perform regripping work without requiring a special repositioner. It is also possible to make the second material support device 7d small, for example, so that the first material support device can pass under its armpit during work. With such a configuration, for example, after the second material support device 7d delivers the product to the carry-out conveyor 33, when the first material support device 7c is waiting for parts, the 1. It becomes possible to go to the material supply device 29 side through the underarm of the material support device 7c.

As can be understood from the above description of the embodiments, the gist of the present invention is as stated in the claims for utility model registration, and as is clear from the description, the present invention is applicable to the press brake 3. In the processing area, a plurality of molds for different processing are provided separately in the left and right direction, and an industrial robot 7 is provided which is movable in the left and right directions along a guide section 5 provided on the front side of the press brake 3. The industrial robot 7 is equipped with a plurality of processing stations that can freely supply the material gripped by the material gripping part 17 to each of the molds, and one processing station is provided between each of the processing stations. A turntable 23 is arranged to rotate the product when transferring the product from one industrial robot 7 of one station to the other industrial robot 7 of the other processing station. A material supply section for supplying materials is provided on one side of one of the processing stations, and a product receiving section for receiving products is provided on the side of the other processing station.

Therefore, according to the present invention, it is possible to easily perform multiple different press processes on the same material, and it is also easy to change various press processes, which significantly improves the efficiency of high-mix, low-volume production. It is effective.
