【Example】

Hereinafter, an embodiment of the present device will be described based on the left sectional view of FIG. 1 and the front sectional view of FIG. 2. The proposed device 11 is a molded product horizontal take-out conveyor 1.
2 and a receiving conveyor 13, and the former molded product lateral take-out conveyor 12 is made up of a guide mechanism 18 and a flexible take-out tool 17. The guide mechanism 18 includes a pair of left and right stands 1 erected on the outside sides of the separation area G of the upper and lower molds 5a and 5b.
9, 19, and a pair of beam-shaped or rail-shaped horizontal guide parts 14, 14 disposed horizontally on the left and right sides of the outside of the separation area G, and each horizontal guide part 14, 14 has a It is pivotally mounted to the upper part of the stands 19, 19 by means of a pivot 20 in a cantilevered manner so as to be able to swing up and down. A swing operating tool 25 is attached to the upper part of the stand 19, which allows the pivot 20 to be
By rotating the horizontal guide portion 14, the horizontal guide portion 14 is raised and swung from a horizontal state (the state shown by the solid line in the figure) to a nearly vertical state (the state shown by the two-dot chain line in the figure). . An idler 22 is arranged at the swinging tip of the horizontal guide part 14, and an idler 23 and a drive wheel 24 are arranged inside the stand 19. 27, 27
are strung up on both the left and right sides. The endless chain 27 forms a track that changes direction from the end of the horizontal guide portion 14 on the side of the pivot shaft 20 toward the drive vehicle 24 and then almost vertically downward.
Therefore, the end on the side of the pivot shaft 20 becomes the direction changing section 15, and the area between this direction changing section 15 and the driving wheel 24 becomes the hanging guide section 16. Also, stand 1
A rotary operating tool 26 is attached to the lower part of the rotary operating tool 9, and by rotating the drive wheel 24 with this tool, the endless chain 27 is rotationally driven in a desired forward or reverse direction. The carrying tool 17 is the endless chain 2
It consists of a predetermined number of support members 28, 28, etc., in the form of rods or strips, whose right and left ends are connected to the endless chain 27 within a certain range of 7, arranged at appropriate pitches P. With this configuration, the carrying tool 17 has flexibility and moves along the trajectory of the endless chain 27. In this embodiment, the carrying tool 17 is
The position of the molded product receiving area A guided by the horizontal guide part 14 and the exit position J guided by the hanging guide part 16
(The upper and lower molds 5a inside the stands 19, 19,
It is configured to reciprocate via a direction changing section 15 between a position that does not interfere with the separation operation of 5b. Further, the carrying tool 17 is
When retreating from the molded product receiving area A to the exit position J, the conveyor changes its shape and passes through the direction change 15 to form the discharge end 12a of the conveyor. The receiving conveyor 13 is arranged adjacent to the molded product lateral take-out conveyor 12, and the guide roller 2
9, 29... and belt conveyors 30, 30... which move up and down between the respective guide rollers 29, 29.... The guide roller 29 at one end forming the carry-in end 13a is taken out laterally and is moved to the carry-out end 12 of the conveyor 12.
Placed close to a and following the loading surface 1
The height positions of the respective guide rollers 29, 29, .
Since the height position is approximately equal to that of the receiving area 7a, the molded product E carried laterally from the receiving area A is smoothly delivered to the carrying-in surface 13b. Once the molded product E is received on the carry-in surface 13b, the belt conveyors 30, 30 rise to lift the molded product E from the carry-in surface 13b, and carry it out to the next process. It should be noted that the structure of the receiving conveyor 13 is not limited to the above, but may be modified as appropriate depending on the equipment for the next process. For example, although not shown, a receiving conveyor can be constructed using a table lifter with a moving vehicle whose carrying surface is formed of rollers, a cart whose carrying surface is formed of an air table and which receives molded products in a floating state, etc. It is also possible to do so. The operating mode of the present device 11 configured as described above will be described as follows. During the press molding process, the take-out tool 17 of the lateral take-out conveyor 12 is placed in a standby state at an exit position J where it does not interfere with the press molding machine 5. After the press molding process is finished, when the upper mold 5a is raised together with the molded product E and the molded product receiving area A is formed between it and the lower mold 5b, the lifting tool 17 moves from the exit position J to the molded product receiving area A. The molded product E removed from the upper mold 5a is received. Continuing, carry-out equipment 1
7 retreats in the side-carrying direction (arrow H direction), and as it passes through the direction changing section 15 while being deformed, it backs up the molded product E and forces it from the carry-out end 12a to the carry-in end 13a of the receiving conveyor 13. Deliver. Thereafter, the take-out tool 17 moves to the exit position J and waits until the next molding process. On the other hand, the molded product E sent to the carry-in surface 13b of the receiving conveyor 13
are transported to the next process by the elevated belt conveyor 30. By the way, when performing maintenance and inspection of the press molding machine 5 or replacing the upper and lower molds 5a, 5b, the horizontal guide portion 14 of the horizontal take-out conveyor 12 located around the press molding machine 5 becomes an obstacle to these operations. However, in the present apparatus, since the horizontal guide part 14 is raised and swung to a substantially vertical position via the pivot shaft 20 by the swiveling operation tool 25, a wide working space can be formed around the press molding machine 5. Therefore, maintenance and inspection work can be performed extremely easily. Although the present invention has been described above with respect to a press molding machine that molds bathtubs and the like, it can also be applied to molding machines that mold other products. In addition, the present invention does not preclude making appropriate changes depending on the mode of implementation.

[Effect of the idea]

The device of the present invention exhibits the following practical effects. The guide mechanism of the molded product horizontal carry-out conveyor has a structure in which the horizontal guide part and the hanging guide part are connected via the direction change part, so the overall length as seen along the carry-out direction is much shorter than before. can do. Therefore, with the present device, there is no need to secure a large space around the press molding machine for installing a conveyor, and as a result, it is possible to increase the number of press molding machines installed per factory floor area. Since the conventional transfer tool that can be moved vertically and horizontally is not required, the device of the present invention improves the work efficiency of receiving the molded product carried out laterally and carrying it out to the conveyor. Furthermore, since the molded product is only moved in a substantially horizontal direction, there is little risk of damaging the molded product during transfer, resulting in an increase in yield. Furthermore, the molded product cost can be reduced by reducing the equipment cost by omitting the transfer tool. When performing maintenance inspections on the press molding machine or replacing the upper and lower dies, the horizontal guide section of the horizontal carry-out conveyor can be raised and swung to an almost vertical position, creating a wide working space around the press molding machine. This greatly facilitates maintenance and inspection work.
