Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is an unmanned system that automatically takes out a bag-like molded product from a split mold and transports it to the next process, and at the same time automatically assembles the split mold. By doing so, it provides high-performance manufacturing equipment to the ceramics manufacturing industry.

(Prior art) Traditionally, bag-shaped ceramics used split molds.
It takes 2 to 30 minutes to take out the molded product and reassemble the split mold.
Since the process required three people and was impossible to fully automate, there was a limit to how much efficiency could be improved for the mass production of bag-like ceramics.

(Problems to be Solved by the Invention) The present invention achieves high efficiency in the mass production of bag-like ceramics by completely automating the process of manufacturing bag-like ceramics without requiring any human labor. Developing a device that can do this has been an issue in the industry.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides two sets of suction gripping tools, one for taking out an upper mold and the other for taking out a molded product, equipped with a vertical movement device, in a dryer or the like. It is operated in conjunction with the intermittent running of the conveyor, and is designed to simultaneously transfer the upper mold and take out the molded product from the lower mold.

(Structure of the Invention) The structure of the present invention will be explained based on the drawings of the embodiment. As shown in FIG. It is located close to the conveyor C of the machine K and also close to the conveyor H of the molded products W.

In the figure, S indicates a raw material supply device.

The take-out device 1 will be described in detail. As shown in FIGS. 1 to 4, a main sliding column 3 is slidably fitted onto a slide bar 2 provided parallel to the conveyor C of the dryer K. A vertically moving air cylinder 5 is installed vertically on the upper surface of the cross beam 4, and an arm 7 is attached horizontally to the lower end of the rod 6 of this vertically moving air cylinder 5.
The upper die suction gripping tools 8, 8 of the upper die D are attached to both ends of the upper die D, and connected to the vacuum pump P by air hoses 9, 9. A rotating main column 11 is rotatably and vertically supported on bearings 10, 10 fixed above and below at approximately midpoint between the conveyor C and the transport conveyor H, and a rotary main column 11 is rotatably supported vertically at the base of the rotating main column 11. a tip 14 of a lever 13 fixed horizontally to a fixed collar 12;
Both ends of the connecting rod 16 are pivoted 17 and 18 between the protrusion 15 provided on a part of the main sliding column 3. Another vertically moving air cylinder 21 is vertically installed on the upper surface of the tip of another lever 20 that is fixed horizontally to another collar 19 that is fixed to the upper end of the rotating main column 11 so as to be adjustable in direction. Another arm 23 attached horizontally to the lower end of the rod 22 of the cylinder 21
The molded product suction gripping tools 24, 24 for the molded product W are attached to both ends of the molded product W.
is installed, and another air hose 9,
9 to connect each other.

Another lever 26 is fixed horizontally to another collar 25 which is fixed to the lower end of the rotating main column 11 so as to be adjustable in direction. The two ends of another connecting rod 30 are pivoted 31 and 32 between them.

In the figure, D′ indicates the lower mold.

(Operation of the invention) The operation of the invention will be explained based on the drawings of the embodiment.

As shown in FIG. 1, in a roller forming machine F attached to a dryer K, raw materials are supplied by a raw material supply device S to a lower mold D' having suction holes Q, as shown in FIGS. 5 and 6. The lower mold D' is attached to the mold receiving part T, the upper mold D is placed on top of the lower mold D', and the upper mold D is brought into close contact with the lower mold D' by suction by the vacuum pump P. Apply rotation, operate the vertical motion cylinder L of the roller forming machine F, lower the roller trowel R into the mold while rotating, and operate the longitudinal motion cylinder M to press the roller trowel R against the side wall of the mold. Shape as follows. When the molding is completed, the roller trowel is removed from the mold, the upper mold D and the lower mold D' are released from the adhesion, and the mold is dried in the dryer K by the conveyor C of the dryer K while holding the molded product W inside. It slowly and intermittently travels around the room to the take-out position. During this time, primary drying is completed.

When the above-mentioned take-out position is stopped intermittently, the upper mold suction gripping tool 8 and the molded product suction gripping tool 24 are in the left position (in FIG. 3), as shown in FIGS. 1 to 3, and at this time, the vertical movement is The cylinders 5 and 21 operate simultaneously to lower both the suction gripping tools 8 and 24, and as shown in FIG. The product suction gripping tools 24, 24 adsorb the molded products W, W in the lower molds D', D' from which the upper molds D, D were removed in the previous process, and
Since the suction between D and the lower dies D', D' is released after the molding is completed, both suction gripping tools 8, 8 and 24, 24 are attached to the upper dies D, D and the molding, respectively, as shown in Fig. 7B. It picks up the items W and W and rises.

As shown in FIGS. 2 and 3, when the drive motor 27 rotates and the levers 13 and 20 rotate in the direction of arrow R via the crank 29, the connecting rod 30, and the lever 26, the slide bar 2 is rotated. The main sliding column 3 moves to the right (in Fig. 3), and as shown in Fig. 8A, the upper mold suction gripping tools 8, 8, which gripped the upper molds D by suction, were emptied in the previous process. The lower mold D′,
The molded product suction and gripping tools 24, 24 move to just above D' and stop, and the upper die suction and gripping tools 8, 8 adsorb the molded products W, W as shown in FIG. 8B (see FIG. 7B). ), the upper dies D, D move down with the lower dies D′,
It is placed on D′.

Next, as shown in FIGS. 9A and 9B, when the upper mold suction and gripping tools 8, 8 and the molded product suction and gripping tools 24, 24 release their suction and rise, the primary drying process on the conveyor H shown in FIG. The completed molded products W, W are transported to a second drying process (not shown).

Next, as shown in FIG. 3, when the drive motor 27 further rotates, the lever 13 and the lever 20 are rotated in the opposite direction of the arrow R' via the crank 29, the connecting rod 30, and the lever 26. Sliding main pillar 3
slides to the left (in FIG. 3) on the slide bar 2 and returns to its original position, and the above-described operation continues in connection with the intermittent running of the conveyor C.

(Effects of the Invention) Since the present invention has the above-described structure, no manual labor is required when transferring a bag-like ceramic molded product formed using upper and lower split molds from primary drying to the next process. The economical effect is enormous because it can be carried out with extremely simple equipment without the need for.
