Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for automatically feeding objects for simultaneous molding, such as sheets, into a foam mold. Trying to get something easy.

Conventionally, in order to integrate a sheet or various molded products with a foamed molded product, each was molded separately, and after molding, the two were integrated using an adhesive. However, with the above method of using an adhesive to integrate the two, the individual molding and joining after molding are extremely troublesome, and sufficient consideration must be given to chemical changes caused by the use of the adhesive. There were also significant drawbacks and inconveniences in terms of manufacturing costs.

Therefore, in order to eliminate these drawbacks and inconveniences, sheets or various molded products (e.g. vacuum formed products,
A simultaneous molding method has been developed in which an injection molded product, etc.) is set in advance in a foam mold and integrated with the foam molded product, but it is difficult to set the object for simultaneous molding using the sheet or various molded products in the mold. This was done manually by workers, which was very time-consuming, and the mold closing and opening were hydraulically operated, and although safety devices were installed, the work required workers to enter the mold. was fraught with danger.

Therefore, the present invention solves these problems all at once and makes it possible to automatically supply objects for simultaneous molding such as sheets, and its structure includes a suction device for the objects for simultaneous molding such as sheets. Separately from the foam molding mold, the cylinder mechanism is provided with a cylinder mechanism in which the suction cup part is pivotally supported at the end thereof, and a cylinder mechanism or a conveyance mechanism capable of supplying the object for simultaneous molding to the operating position of the suction tool. A cylinder mechanism equipped with a suction cup is equipped with a turning mechanism that changes the direction of the object to be set in the foam mold after adsorption of the object for simultaneous molding. The apparatus is equipped with a suction device capable of suctioning the object, and the rotating mechanism is further comprised of a pulling member such as a rope or chain with one end attached to a part of the suction device. It is characterized in that the object for simultaneous molding is provided so that its direction can be changed by a turning mechanism using the above-mentioned pulling member as the cylinder mechanism on the suction tool side operates.

Next, embodiments of the present invention will be described below with reference to the drawings.

1 and 2 are cylinder mechanisms using air etc. installed above the foaming mold; cylinder mechanism 1;
is supported by a pedestal 11. The other cylinder mechanism 2 is supported by a pin 12 at the tip of the piston rod of one cylinder mechanism 1.
Reference numeral 3 denotes a suction cup, on which an appropriate number of suction tools 31 are attached for connection with a vacuum pump, and this suction cup 3 is pivotally supported by a pin 21 at the tip of the piston rod of the cylinder mechanism 2. Reference numeral 32 indicates a hook or the like attached to the end of the suction cup 3 with the suction device 31 attached.

4 is a sheet exemplified as an object for simultaneous molding, and is stored in a sheet receiving box 41. Mechanism 5 is used to enable feeding. 43
A bracket is attached to a part of the seat receiving box 41, and the tip of the piston rod of the cylinder mechanism 5 is fixed to this bracket 43. Further, instead of the cylinder mechanism 5, a conveyance mechanism such as a conveyor using a reciprocating belt or chain may also be used.

Furthermore, 22 is a hook or the like attached to the upper end of the cylinder mechanism 2, which is connected to the hook or the like hook 32 on the suction cup side by a rope 6 or an alternative chain or the like. These mechanisms are, as will be described later, a turning mechanism that changes the direction of the sheet 4, which has been sucked by the suction tool 31, as the cylinder mechanism 2 on the suction tool side descends to suit the setting direction in the foam mold. It can be.

Reference numeral 7 denotes a foaming mold, to which an inner mold 71 is attached, and a suction cup 73 with a suction tool 72 is attached to this inner mold 71, and is connected to a vacuum pump. Reference numeral 8 denotes a mold mounting plate, which can be moved forward and backward by a cylinder mechanism 9 using hydraulic pressure or the like. Reference numeral 10 denotes a cylinder mechanism for air, etc., which is adapted to move the above-mentioned cylinder mechanisms 1 and 2 in the horizontal direction in the figure.

When feeding the sheet 4 into the foam mold using the above device, the sheet receiving box 41 is sent below the suction tool 31 by the action of the cylinder mechanism 5 (see Fig. 1), and the cylinder mechanism 1, push down the cylinder mechanism 2 on the suction tool side and remove the suction tool 31.
The attached suction cup 3 is lowered and pressed against the sheet 4 in the sheet receiving box 41 located below the suction tool 31 (see FIG. 2). Next, after the sheet 4 is suctioned by a suction tool 31 connected to a vacuum pump, the cylinder mechanism 2 is once pushed up and returned by the cylinder mechanism 1 (see FIG. 3). After that, actuate the cylinder mechanism 5 to pull the sheet receiving box 41 (see Fig. 4), and after leaving enough space for the sheet 4 to fall, actuate the cylinder mechanism 2 and lower the suction cup 3 with the suction device 31. let In this case, a hook or other hook 32 on the suction cup 3 side, and a hook or other hook 2 on the cylinder mechanism 2 side.
2 are connected by a rope 6 or the like, the suction cup 3 is rotated 90 degrees around the pin 21 and turned into a direction suitable for setting into the foam mold (see Fig. 5). ). After the direction is changed, the cylinder mechanism 2 is pushed down by the operation of the cylinder mechanism 1, and the sheet 4 is lowered until it reaches the position of the inner mold 71 while being sucked by the suction tool 31 (see FIG. 6). Then, by pushing the cylinder mechanisms 1 and 2 horizontally in the figure with the cylinder mechanism 10, the sheet 4 is joined to the inner mold 71, and after joining, the sheet 4 is moved by the suction tool 72 of the suction cup 73 on the mold side. , and the suction tool 31 that has been suctioning until now releases its suction to the sheet 4. Then, the cylinder mechanism 10 is returned to its original position, and the cylinder mechanism 2 is pulled up by the operation of the cylinder mechanism 1, and the suction cup with the suction tool 31 is moved out of the mold by the operation of the cylinder mechanism 2 itself.

Thereafter, the foaming mold is clamped, and simultaneous molding of the sheet 4 and the foamed molded product is performed.

In addition, in the above implementation, regarding the cylinder mechanism 10 that moves the cylinder mechanisms 1 and 2 in the horizontal direction in the figure, a suction cup 73 with a suction tool 72 on the foam mold side is installed on the movable mold side, and the cylinder mechanism 10 moves the cylinder mechanisms 1 and 2 in the horizontal direction in the figure. If it moves slightly and can adsorb the sheet 4, it may not be necessary.

Furthermore, in place of the sheet 4, it goes without saying that various molded products (vacuum molded products, injection molded products, etc.) can be implemented in the same manner as the above-described embodiment. Further, when the foam molding mold is of a vertically open/close type, a supply device for the molded object may be installed on either the left or right side.

As described above, according to the present invention, objects for simultaneous molding such as sheets can be set in a foam mold very easily and reliably, and a wide variety of composite molded products (simultaneous molded products) can be obtained. Moreover, since the setting into the mold is automated, there is no operational danger at all, and safe and easy-to-manage supply can be achieved.

In addition, the structure is simple, and the object to be molded simultaneously, such as a sheet to be inserted and set into the mold, can be positioned reliably, and the supply part side can be assembled separately from the mold to mold it. It can be easily assembled by joining the mold. Therefore, there is no restriction on the mold structure, and depending on the opening/closing direction of the mold, the feeding device can be installed from above, from below, or in either the left or right direction. There are no restrictions and it is easy to install.
