Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention particularly relates to a press molding machine unit that pressurizes, heats and vulcanizes a rubber product.

[0002]

[Prior art]

 Conventionally, a structure in which a plurality of press molding machines are unitized has, for example, six rubber press molding machines (hereinafter simply referred to as molding machines) 1 to 6 arranged in a line as shown in FIG. A work space 8 for an operator to work or move is arranged, and a work table 9 is arranged on the opposite side of the unit 7 with the work space 8 interposed therebetween. On the workbench 9, there is a space for placing pre-molded rubber material, molded products, etc., a space for placing a mold removed from the molding machine and charging unvulcanized rubber material into it, or for taking out molded products from it. Is provided.

[0003]

[Problems to be solved by the device]

 As an example of the size of the molding machine unit 7 having the above structure, when the width of each of the molding machines 1 to 6 is 1.5 m, the distance between the center positions of the molding machines 1 and 6 at both ends is 7.5 m. Become. The worker works while moving this distance. With such a configuration, there is a problem in that the worker's movement distance is large, work efficiency and hence productivity is poor, and the worker is easily tired. Incidentally, in the above example, when the worker starts the work from the molding machine 1 and finishes the work of all the other molding machines 2 to 6 and returns to the molding machine 1 again, the worker will move a minimum of 15 m. . Further, in the above configuration, since the workbench 9 is behind the worker, the worker has to look back for each work, and such an operation not only causes work efficiency to deteriorate, but also has a problem in work safety. there were.

[0004]

[Means for Solving the Problems]

 The press molding machine unit according to the present invention is arranged in a U-shape and surrounds the work space necessary for one operator to work and the center of the U-shape. It is provided with the first press-molding means arranged on the sides and the second and third press-molding means respectively arranged on the two sides at both ends of the U-shape.

In the present invention, the first press-molding means can be constituted by press-molding means whose molding time is set shorter than the molding times of the second and third press-molding means. .

In the present invention, each of the first to third press-molding means can be composed of one press molding machine.

In the present invention, each of the first to third press molding means may be composed of two press molding machines.

[0008]

[Action]

 One worker holds the first to third press-molding means and controls the driving. The worker faces each pressing means and works. When moving to work with a different press-forming means, the operator only has to turn his body towards the corresponding press-forming means and move slightly.

When the molding time of the first press molding means is set to be the shortest, the working frequency of the first press molding means is higher than that of the second and third press molding means. Therefore, the manufacturer will work on the second or third press forming means while working facing the first press forming means, and the frequency of changing the body orientation will be low.

【Example】

 FIG. 1 shows an embodiment of the present invention in which three molding machines 10, 11 and 12 are arranged in a U-shape. The molding machine 10 arranged on the central side of the U-shape forms the first press forming means, and the molding machines 11 and 12 arranged on the two sides of the two ends of the U-shape form the second and third press-molding means, respectively. Constitutes a means. The width of each of the molding machines 10, 11 and 12 is about 1.5 m, and a space of about 1.5 m square surrounded by these molding machines 10, 11 and 12 becomes the working space 13. Reference numeral 14 denotes one worker who works in this work space 13. , 15 are four work benches arranged between the molding machines 10, 11, 12 and at both ends. On the work benches 15, 15, ..., Unvulcanized rubber material, molds used in the molding machine, jigs, rubber moldings, etc. are placed. Here, the work refers to a work in which an unvulcanized rubber material is charged into a mold, the molds are superposed and mounted on a molding machine, the mold is removed after molding, and the molded product is divided and taken out. The workbench 15, 15, ... Can have a two-stage structure to reduce the space.

The worker 14 drives the three molding machines 10, 11, and 12 at the same time, and holds the work while shifting the work time. If the vulcanization molding time of the molding machine 10 is shorter than that of the other two molding machines 11 and 12, the worker 14 spends most of the working time on the molding machine 10, and In the meantime, the work of the molding machines 11 and 12 is performed. When the work is transferred from the molding machine 10 to the molding machine 11 or the molding machine 12, the worker 14 hardly needs to walk, and only needs to change the direction of the 90 ° body.

FIG. 2 shows another embodiment of the present invention in which two molding machines are arranged on each side of the U-shape. That is, two molding machines 16a and 16b are arranged on the central side of the U-shape to form the first press molding means 16, and two molding machines 17a and 17b and two molding machines 17a and 17b on the other two sides of the U-shape, respectively. 18a and 18b are arranged. In the molding machines 17a and 17b, the second press-molding means 17 and the molding machines 18a. The third press-molding means 18 is constituted by 18b. A working space is a space 19 of about 3 m square surrounded by the first to third press molding means 16, 17, and 18. Reference numeral 20 denotes workers 21, 21, 1, ..., Four work benches arranged between the press forming means 16, 17, 18 and at both ends.

In the unit consisting of the above six molding machines, assuming that the width of each molding machine is 1.5 m as in the above-mentioned example, the distance between the work positions is the molding machine in each press molding means, such as the molding machine 16a, The distance a between 16b is a = 1.5 m, the molding machine between adjacent press molding means is, for example, the distance b between the molding machines 16b and 18a is 1 m, and the distance between the molding machines 17b and 18b is c = 3 m. Therefore, when each of these molding machines is operated once to return to the original position, the shortest movement distance of the worker 20 is 9.5 m. This is about 63% of the moving distance in the conventional structure.

Here, when the vulcanization molding time of the molding machines 16a and 16b of the first press molding means 16 is set to be shorter than that of the molding machines of the second press molding means 17 and 18, The frequency of work in the 1 press molding means 16 becomes the highest. Therefore, the worker 20 has the longest time to face the first press-molding means 16, and the second and third press-molding means 17 and 18 are operated in the meantime. Therefore, the worker 20 only has to change his or her body 90 degrees to the right or 90 degrees from the position facing the first press forming means 16 and move a few steps.

Of the molding machines of the second and third press molding means 17 and 18, the molding time of molding machines 17a and 18a closer to the first press molding means 16 is set to the molding machine 17b. If it is set shorter than that of 18b, the movement distance of the worker 20 can be further shortened.

[0016]

[Effect of device]

 According to the present invention, since a plurality of molding machines are arranged in a U-shape centering on the work space, the movement distance can be shortened when one operator holds and operates these machines. Specifically, the distance could be shortened by about 27% as compared with the conventional case where the molding machines are arranged in a straight line.

Further, according to the present invention, by setting the molding time of the molding machine to be shorter in the central molding machine, the frequency of work in the central molding machine is increased, and the work of the left and right molding machines is interrupted between the molding operations. Will be done. As a result, the transfer distance of the worker was further shortened, and it was confirmed that the work efficiency was improved by about 20%.

Further, according to the present invention, since the number of movements of the worker to swing his back to work is extremely small, it is possible to reduce the fatigue of the worker and increase the safety of the work.
