Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has seven lower molds that are alternately associated with one upper mold that is controlled to move up and down. This invention relates to a press molding machine for flower pots that allows continuous and efficient removal.

Conventionally, such flowerpots were molded by potter's wheel molding using raw material with a relatively high moisture content, so during the drying stage, it took a long time for the primary drying period until the molded product was released from the plaster mold. Therefore, it has disadvantages such as poor production efficiency and the need to keep a large number of plaster molds.

In view of these drawbacks, the present invention enables the molding of flowerpots using a press using raw materials with relatively low moisture content, and also allows the flowerpot to be immediately removed from the mold and subjected to secondary drying as it is.

In this case, when the suction mechanism 16 supported by one side slider 27 is positioned facing above the raw material holder 13 and the lower mold 4, the suction mechanism 16' supported by the other side slider 27' is positioned opposite to the lower mold 4'. Side sliders 27 and 27' are connected by wires 31 and 31' so as to be located above and opposite to the molded product holder 14'.

．． The movable molds 42, 42' fitted to the bottoms of the lower molds 4, 4' are pushed up through the movable molds 41'.

Next, to explain the operation of the flowerpot press molding machine according to the present invention, the raw materials w, w', etc. cut into a predetermined shape are placed on the raw material holders 1 at the rear of both sides of the main body 1 by an operator A at the rear of the main body 1. .13' are placed alternately.

Next, in explaining the operation of each mechanism related to the molding operation, one lower mold 4 is in an outward movement position and has a molded product F after molding inside, and the other lower mold 4' is It is assumed that the upper mold 3 is located at a position facing below and contains a raw material W inside thereof (FIG. 8).

In this state, the left adsorption mechanism 16 is attached to the raw material holder 13.
The suction mechanism 16' on the right side is located oppositely above the molded product holder 14' at the outward movement position of the lower mold 4.

In this state, the upper die 3 is lowered and the raw material W in the lower die 4' is
During press molding, the raw material suction holding tool 18 and the molded product suction gripping tool 19 are lowered by the action of the elevating cylinder 21 of the suction mechanism 16 in the left feeding/unloading mechanism section 15, and the raw material on the raw material pedestal 13 is lowered. After adsorbing W and the molded product F in the lower mold 4, it returns to the upper position by the action of the elevating cylinder 21.

During this step, in order to facilitate the release of the molded product F in the lower mold 4, the movable mold 42 is raised via the knockout pins 37 and 37' by the action of the knockout cylinder 38, and the molded product F is attracted to the molded product. The device is configured to allow the lifting time to reach the suction position by the gripping tool.

Next, by the action of the movement control cylinder 32, the suction mechanism 16
is moved forward integrally with the side bracket 26, and the raw material suction gripping tool 18 is placed above the lower mold 4.
9 are positioned above and opposite to the molded product holder 14, respectively.

The side slider 27' on the opposite side (right side) loading/unloading mechanism section 15' is connected by wires 31 and 31', so it moves backward in the opposite direction to the left side side slider 27, and is used for adsorption of raw material in the suction mechanism 16/. Gripping tool 1
8' and the gripper 19' for adsorbing the molded product are moved to a position facing above the outward movement position of the raw material holder 13' and the lower die 4'.

Next, in the suction mechanism 16 in the forward movement position, the raw material suction gripping tool 18 and the molded product suction gripping tool 19 are lowered again, and the suction is released to move the raw material W into the lower mold 4 and onto the molded product holder 14. After transferring the molded products F to , it returns to the ascending position.

After the molding is completed, when the upper mold 3 rises, the slide base 8 moves to the right to a predetermined position due to the action of the embossing cylinder 9, and the lower mold 4 into which the raw material W has been charged faces the lower part of the upper mold 3. The lower mold 4' with the molded product F is moved outward to the right (FIG. 9).

Subsequently, while the upper mold 3 descends again and the raw material W in the lower mold 4 is press-molded, the raw material W on the raw material holder 13' is similarly released by the action of the loading/unloading mechanism 15' on the opposite side (right side). Raw material W
' and the molded product F in the lower mold 4' are simultaneously transferred into the lower mold 4' and onto the molded product holder 14', and the molded product F on the molded product holder 14 is transferred to the front part of the main body 1. It is taken out by operator B, and thereafter continuous molding is performed by repeating each operation related to the molding operation.

In short, in the present invention, seven lower molds 4, 4' are mounted in parallel on a slide base 8 provided below the upper mold 3 so as to be slidable from side to side. The slide base 8 is controlled to reciprocate from side to side so that it moves alternately to positions facing each other in the direction, and a raw material holder 13° 13' is provided at the rear opposite to the left and right movement positions of the lower molds 4, 4', and at the front there is a A molded product holder 14.14' is provided, and on both sides of the main body 1 there are a raw material holder 13.13', a lower mold 4, 4', and a molded product holder 14.1.
The raw material W on the raw material receiving table 13.137 and the molded product F in the lower molds 4, 4' are sucked at the same time by being controlled to move back and forth alternately over the same distance between them. Within 4/, the molded products F are suctioned and transferred onto the molded product holders 14 and 14', respectively, and the loading and unloading mechanism parts 15 and 15' are installed, respectively, and the lower molds 4 and 4' are moved left and right and loaded and unloaded. Mechanism part 1
5 and 15' are operated alternately in relation to the molding operation, so that while the raw material W on one lower mold 4' is being press-molded, the molded product F on the other lower mold 4 is press-molded. pedestal 1
Since the raw material W for the next molding can be loaded into the lower mold 4 at the same time as the raw material W and the molded product F are transferred onto the upper mold 4, smooth and reliable press molding can be achieved without causing any time loss in the molding cycle due to the transfer of the raw material W and the molded product F. The operation can be performed continuously, and the molding operation is performed by the press, so
Since a raw material W with a relatively low moisture content can be used, it is possible to remove the mold immediately after molding and use it for secondary drying, without requiring primary drying as in conventional potter's wheel molding.

In addition, the loading/unloading mechanism parts 15, 15' are connected by wires 31, 31' so that they can be moved back and forth alternately, so that the back and forth reciprocating movement of the loading/unloading mechanism part 15, 15' is controlled by a single movement control cylinder. 32 allows simultaneous alternating movement and simplifies the mechanism, which has great practical effects.
