Description

[Detailed Description of the Invention] (Objective of the Invention) (Industrial Application Field) This invention is used in potter's wheel molding of ceramics, by quickly molding a heavy molded product and conveying it inverted onto a conveyor. , provides the pottery industry with a potter's wheel moving device that is useful for efficient molding of large potter's wheel molded products.

(Prior art) Conventionally, Japanese Patent Application Laid-Open No. 58-65612 and Utility Model Application No. 53-
In the potter's wheel molding machine as disclosed in No. 54947 etc.,
The potter's wheel is fixed in the same position and the upper molding part is moved up and down to form the mold, and then when the molding trowel rises and the upper part of the mold is opened, the mold is removed from the potter's wheel and used. There is.

Normally, in that case, the molds are attached and removed by hand, but in the case of fully automated molds, the molds are placed in succession on a chain conveyor or turntable, and the potter's wheel is moved up and down within it to raise and lower the molds. At the same time, the mold is pushed up to form the mold, and when finished, it is lowered and left at its original position on the chain conveyor or turntable.
The method used is to move the table, etc. and repeat this process, but all of these methods are possible when molding lightweight small items, but are impossible when molding large, heavy items due to the large capacity and load. . Furthermore, when attaching and detaching the mold using a potter's wheel, it is impossible to do this by hand for heavy and large molded products, and even if an automatic detacher is used, it is impossible because the molding head of the molding machine is located at the top. Even if it is carried out using a chain conveyor or a turntable, the dowels on the potter's wheel (the container into which the mold is inserted, chucked, and rotated) are deep, and the vertical motion of the potter's wheel is not comparable, making the dowels and molding difficult. Since the mold could not be removed, it was impossible to move the mold laterally on the chain conveyor or turntable, and this method was also impossible.

(Problems to be Solved by the Invention) This invention allows the potter's wheel to be moved from the molding position to the mold attachment/detachment position while the mold is attached to the potter's wheel, and the automatic attachment/detachment machine is used to easily and safely attach and detach the mold. The purpose of this project is to develop a device for moving a potter's wheel that can be used easily and quickly.

(Structure of the Invention) (Means for Solving the Problems) The basic structure of the present invention as a means for solving the above-mentioned problems is that In this device, a potter's wheel equipped with a dowel for storing a plaster mold is rotatably provided on a slidable slide base, and the potter's wheel is moved through a cylinder to the molding position and A slide roller is provided on one side of a rotating arm that is provided with a rotatable molding trowel that can reciprocate between molded product take-out positions, and a main cam and a slide cam are separately provided coaxially. , and the main cam is engaged with the aforementioned slide roller, while the other side of the slide arm having a slide roller on one side is pivoted to one side of the slide base, and the slide roller of the slide arm is engaged with the slide cam. It is something that has been done.

(Function) To describe the function of this invention, the reversing machine connected to this device is at the rising end, the forming trowel is at the rising position, and the dowel with the plaster mold inside is at the fixed position at the take-out position. When the clay is poured into the plaster mold, the potter's wheel with the plaster mold on the slide base moves to the molding position with its driving part, the potter's wheel and camshaft rotate, and the molding trowel rotates while removing the plaster. It enters the mold and molding begins. During this time, the potter's wheel continues to rotate.

Next, during molding, the molding is finished by moving the potter's wheel over a small range using a slide cam via a slide arm against the pushing force of the cylinder.

When molding is finished and just before the molding trowel is raised, the slide arm returns, and the cylinder slides the potter's wheel to the leftmost molding position, raising the molding trowel.

Next, the potter's wheel shaft is stopped, the forming iron is placed in the raised position, the camshaft is stopped, and the rotary shaft of the potter's wheel is moved by the cylinder to the take-out position. The reversing machine connected to this device descends with the clamp open, and at the descending end, the clamp simultaneously grasps the plaster mold inside the dowel and the empty plaster mold on the conveyor, and the reversing machine ascends to the ascending end. At the rising end, it turns 180 degrees and descends to the descending end, then opens the clamp, releases the empty plaster mold into the dowel, and ascends to the rising end. Further, the plaster mold containing the molded product is conveyed by a conveyor, and the plaster mold to be molded next is placed in the predetermined position. The above cycle is automatically repeated.

(Example) This invention will be explained based on the drawings of the example.
As shown in FIGS. 1 to 4, the potter's wheel type moving device 1 has a slide base 3 on one side of the upper surface of the base 2.
is mounted so as to be slidable in the left and right direction (as shown in Fig. 1), and a potter's wheel 5 with a dowel 4 fixed to the upper end is vertically hung on this slide base 3 via a potter's wheel shaft case 6, and is rotatably mounted on this base 3. The installed potter's wheel drive motor 7
A V-belt 10 is hung between the driving pulley 8 and the driven pulley 9 provided on the outer periphery of the dowel 4 so that the drive can rotate freely, and a pedestal 12 of a forming table 11 is provided protruding from the upper surface of the base 2. The rotating arm 14 of the molding table 11 is rotatably attached to this pedestal 12 by a support shaft 13, and the rear part of this rotating arm 14 (the left part in FIG. 1)
A slide roller 15 is rotatably attached to the shaft, and a balance weight 1 is attached to the rear of the rotating arm 14.

(Effects of the Invention) Since the present invention has the above configuration, it has the following advantages.

In this invention, a slide roller is provided on one side of a rotating arm provided with a forming iron, a main cam and a slide cam are separately provided coaxially, and the main cam is engaged with the slide roller, and the other side is provided with a slide roller. The other end of the slide arm, which is equipped with a slide roller, is pivoted to one side of the slide base, and the slide roller of the slide arm is engaged with the slide cam, so that the potter's wheel can move vertically within a predefined range. The main cam for rotation is driven via a slide roller on the potter's wheel side, and a slide cam installed coaxially with the main cam is also driven. Since it is engaged with the slide roller of the arm, the potter's wheel follows the rotation of the forming iron and moves horizontally over a short distance.

Therefore, since the potter's wheel moves slightly, it is possible to perform a complex molding action in tandem with the rotating action of the molding trowel, ensuring that the molded product is finished in a regular shape that imitates the plaster mold. It will be done.
