Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for simultaneously transferring a plaster mold and a molded product in an automatic ceramic molding device.

Conventionally, in the molding and primary drying process of ceramic products, the molded product is housed inside, a large plaster mold is removed from the conveyor near the end of the primary drying process, and the molded product is taken out of the plaster mold manually or with a take-out device. Two separate and cumbersome steps were required: the molded parts were transferred onto a conveyor for the molding process, and the plaster molds were transferred onto a conveyor for return to the molding process.

This invention solves these problems and separates the molded product from the plaster mold, placing the plaster mold on the pallet of the return conveyor, and removing the molded product from the pallet from which the plaster mold has been removed. The purpose is to transfer the plaster mold and the molded product at the same time in conjunction with intermittent running.

The basic structure of this invention is that in a device that circulates and transfers plaster molds placed face down on a pallet, the forward and return conveyors are placed with their ends in parallel positions^C!

5.26 and the pawls 28.29 of the molded product gripping tool 27 are all attached to the actuator l 18.19, so they act in the closing direction and remove other plaster molds S and the end of the return conveyor 3 in the previous process. The molded products S and S on the pallet T, which were located at a position ly W on the pallet T from the part 4, are grasped.

Next, the lifting drive motor 11 on the frame 10 on the transfer trolley 9 operates again and rotates the crank 21, which guides the cross member 17.17 to the guide column 16.16 via the link 20 and lifts it up to form the plaster mold. S is removed from the molded product 1 (and remains on the outgoing conveyor 2). At the same time, the reciprocating drive motor 31 on the upper frame 30 of the frame 6 is activated, and the reciprocating drive motor 31 is activated via the driven gear 33, crank 35, and link 36. The movable arm 38 moves toward the arrow 1' (
]R/direction (see Fig. 2), the movable trolley 9, which can be freely accessed by wheels 8.8, moves within the lower frame 7 of the frame 6 in the direction of arrow Q through the linkage 39, and the plaster mold The plaster mold S gripped by the claws 25.26 of the gripping tool 24 is transferred directly above the return conveyor 3, and is then gripped by the claws 28.2 of the molded product gripping tool 27.
The molded product gripped by the molded product 9 is transferred directly above the molded product take-out conveyor 5.

The lift drive motor 11 operates again to lower the plaster mold gripper 24 and the molded product gripper 27, and the gripper opening/closing air cylinders 46 and 47 operate in the opposite direction to lower the plaster mold gripper 24 and the molded product gripper 27. When listening to the respective claws 25, 26 and 28, 29 of the molded product gripper 27, the plaster mold S is
The molded product K on the street conveyor 3 is placed on the empty pallet T that has just been taken down, and the molded product is placed on the molded product take-out conveyor 5.

Next, contrary to the previous step, each gripper 24 and 27 is attached to the claw 25.
．． 26, 28, and 29 are raised while being open, and the reciprocating drive motor 31 is driven to move the movable cart 9 in the direction of arrow q/(see FIG. 2) in the opposite direction, and return to the original position. At the same time, the outbound conveyor 2 and the return conveyor 3 move the pallet T by 1@w arrow? When moved in the direction and p/direction (the moving drive device is on the path shown in the figure), the pallet T with the plaster mold S removed and only the molded products placed on it is placed at the end of the outgoing conveyor 2, and the pallet T on which only the molded products are placed is placed at the end of the outgoing conveyor 3. There is no pallet T in the section,
There is a pallet T on which molded products K are placed at a position l@I away from the end of the return conveyor 3.

Next, when the pallet T carrying the molded products K at the end of the outgoing conveyor 2 is pushed in the direction of the arrow Q by the pushing means (path shown) of an appropriate traverser, the end of the outgoing conveyor 2 becomes empty, and the returning conveyor At the end of No. 3 is a pallet T on which molded products K are placed. During this time, the molded product take-out conveyor 5 also moves in the direction of the arrow 1'' [lR force, so that the molded product take-out conveyor 5 below μ of the frame 6 is also empty.

The above operations are performed intermittently in conjunction with each other.

As mentioned above, the plaster mold S and the molded product are transferred at the same time, and these are shown in FIG.

To explain using [Yes] in (2), the l1llL passing order is as follows.

Plaster mold S ■=■→■→ Molded product K ■÷■÷■÷■ ÷■ +■ ÷■ In other words, the work of transferring the plaster mold S to ■U■ and the molded product K to ■
At the same time, the work of transferring to ① is carried out in this converting table 1.

In the above-described embodiments, a plaster mold gripper and a molded product gripper with opposite claws were used, but a vacuum suction type or clamp type gripper may be used depending on the case.

Further, although the transfer machine is installed on the second pallet from the end of the outbound conveyor and the return conveyor, it may be installed on the end of the 53rd pallet or higher.

Since the present invention has the above configuration, it has the following advantages.
