Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a work supply and take-out device for a press molding machine used for pressing fiberboard used as a core material for automobile interior parts.

(Prior art) In order to mold the above-mentioned fiberboard, a mat-shaped molding material made of wood fibers bound with a thermosetting resin is processed using a press molding machine equipped with a mold heated to about 200°C. A method of pressure is being used. Conventionally, a worker would pick up the molding materials one by one from the top of the pallet and place them on the lower mold, and then remove them again manually from the top of the lower mold after press forming, but it took about 10 seconds to feed the molding materials to the press. about 70 seconds,
It takes about 10 seconds to take out the molded product, and the total time is 90
The molding cycle took about seconds. this house,
It is difficult to shorten the press time in order to maintain constant quality of the molded product, and it has been desired to shorten the time for supplying and unloading.

(Problems to be solved by the invention) The present invention solves these conventional problems,
A workpiece supply and take-out device for a press molding machine that can automatically supply molding material to the press molding machine and take out the molded product in a short time, improving press efficiency and shortening the molding cycle. It was completed as a purpose.

(Means for Solving the Problems) The present invention provides a pick-up mechanism for raising the pressed molded product together with the upper die on the upper mold of the press molding machine, and a pick-up mechanism for raising the pressed molded product together with the upper mold, and a pick-up mechanism for lifting the upper mold on one side of the press molding machine. A transfer head is provided with a pick-up needle that can move up and down and enters above the lower mold to supply the mat-shaped molding material onto the lower mold. The present invention is characterized in that a take-out tool is provided which enters between the transfer head and the lower surface of the upper mold at the same timing and receives the uneven plate-shaped molded product removed from the upper mold.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

1 is a press molding machine equipped with an upper mold 2 and a lower mold 3, and these upper mold 2 and lower mold 3 are heated to about 200° C. as described above. Upper mold 2
As shown in the figure, a pick-up mechanism 6 consisting of a cylinder 4 and a needle 5 that can move forward and backward is provided on the lower surface of the device. A transfer head 7 is provided on one side of the press molding machine 1 and can be moved horizontally by a chain drive mechanism (not shown). This transfer head 7
is equipped with a pick-up needle 9 that can be moved up and down by a cylinder 8, and pierces the pine-shaped molding material 50 loaded on the lifter 10, as shown by the imaginary line in FIG. 2 rises, it enters the press molding machine 1 and the molding material 50
can be supplied onto the lower mold 3. Further, on the other side of the press molding machine 1, there is provided a take-out tool 11 which can be entered into the press molding machine 1 by a chain drive mechanism (not shown). As shown in FIG. 1, this take-out tool 11 is controlled so that it enters an intermediate position between the entry position of the transfer head 7 and the lower surface of the upper mold 2 at the same timing as the transfer head 7, and exits at the same timing. There is.

(Function) The press forming machine 1 configured in this way is
While the press is in operation, the pick-up needle 8 of the transfer head 7 pierces the mat-shaped molded material 50 on the lifter 10 as shown in FIG. 2, and is on standby as shown in FIG. The transfer head 7 advances to a position above the lower mold 3 and supplies the molding material 50 onto the lower mold 3. Furthermore, since the upper mold 2 is equipped with a pick-up mechanism 6, when it is raised, the press-molded molded product 51 is pierced by the needle 5 and lifted up while being brought into close contact with the lower surface of the upper mold 2. Then, at the same timing as the transfer head 7 enters the press molding machine 1, the take-out tool 11 enters between the transfer head 7 and the upper mold 2, so that the upper mold 2 is moved from the state shown in FIG. needle 5 to cylinder 4
When the molded product 51 is retracted by the extractor 11
fall on top. After that, transfer head 7 and extractor 1
1 exits the press molding machine 1 at the same timing, the transfer head 7 prepares to supply the next molding material 50 as shown in FIG. It will be sent to.

The operation of each part explained above is shown in a time chart as shown in FIG. 3. That is, in the present invention, by lifting the molded product in the shape of a concave-convex plate upward at the same time as the upper mold 2, the supply of the molding material 50 and the removal of the molded product 51 can be performed simultaneously in parallel. Even if it normally takes 70 seconds, one cycle can be completed in 80 seconds, which greatly contributes to improving press efficiency. In addition, according to the present invention, there is no need for the worker to manually handle the pine-shaped molding material 50, which tends to generate dust, and there is no risk of touching the heated lower mold 3 with one's hands, resulting in great safety and health benefits. It is.

(Effects of the Invention) As is clear from the above description, the present invention enables the feeding of a pine-shaped molding material, which is troublesome to handle, and the removal of an uneven plate-shaped molded product at the same time. It is possible to shorten the time by more than 10% and improve the actual operating rate of the press forming machine.
Since the safety and health effects are also significant, the present invention will greatly contribute to the industry as a workpiece supply/take-out device for press molding machines that solves the problems of conventional press molding machines.
