Description

[Detailed Description of the Invention] (Objective of the Invention) (Industrial Application Field) This invention is a process for rapidly forming a heavy molded product in Rokup molding of ceramics and conveying it inverted onto a conveyor. This provides the ceramics industry with a four-axis moving device that is useful for the efficient molding of large-cut potter's wheel molded products.

(Prior art) Conventionally, Japanese Patent Application Laid-Open No. 58-656119 and Utility Model Application No. 53
In the potter's wheel molding machine as disclosed in No. 54947, all four potter's axes are fixed at the same position and the upper molding section is moved up and down to perform molding, and then the molding trowel is raised to move the mold. When the upper part is opened, the molding pot is attached and detached from the potter's wheel shaft.

Normally, in that case, the molding pot is attached and removed by hand, but in the case of fully automatic, the molds are placed in succession on a chain conveyor or turntable, and the potter's wheel is moved up and down by the width of the potter's wheel to raise the pot. When the mold is finished, the mold is pushed up and molded, and when the mold is finished, it is lowered and placed in its original position on a chain conveyor or turntable, the table etc. are moved, and this process is repeated. This is possible when molding lightweight small items, but is not possible when molding large, heavy items due to the large capacity and load. In addition, when attaching and detaching the molding m from the potter's wheel axis, it is impossible to do it by hand with claw-shaped Mars moldings, and even if you use an automatic attachment and detachment device, it is impossible because the molding head of the molding machine is located at the top. Furthermore, even if the process is carried out using a chain conveyor or a turntable, the depth of the dowel on the potter's wheel spindle (the container into which the mold is completely inserted, chucked, and rotated) is deep, and the vertical motion of the potter's wheel spindle is not comparable to that of the dowel. Since the mold cannot be removed, it is impossible to move the mold laterally on a chain conveyor or turntable, and this method was also impossible. (Problem to be solved by the invention) This invention A moving device for the potter's wheel axis that allows you to move the Roxy axis from the molding position to the molding attachment/detachment position while attached to the potter's wheel axis, and then use an automatic attachment/detachment machine to easily, safely, and quickly perform the attachment/detachment. This is what we are trying to develop.

(Structure of the Invention) (Means for Solving the Problems) The basic tenet of this invention as a means for solving the above-mentioned problems is to provide four axes together with a drive device on a slidable base. , the slide base is made reciprocatable between the molding position and the take-out position by a cylinder, a main cam for rotation and a slide cam for pressing slide are provided on the camshaft for rotation of the rotating arm, and a link mechanism is used to connect the cylinder and the slide base. At the same time, the sliding force and the slide base are connected by a slide arm, and the rotation of the rotating arm and the large movement of the slide base between the molding position and the take-out position and the small movement of pressing during molding are linked. It is something.

(Function) To describe the last month 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 take-out position. When the clay is poured into the plaster mold at the position, the plaster mold on the state base moves to the molding position together with the Roku A-axis and the drive unit, the Roku V-axis and the cam shaft rotate, and the molding trowel rotates. While doing so, it enters the plaster mold and molding begins. During this time, the gastric axis continues to rotate.

Next, during molding, the state cam is used to finish the molding by moving the locle shaft by a small range against the pushing force of the cylinder via the slide arm.

Immediately before the molding is finished and the molding iron is raised, the slide arm returns and the cylinder slides the four shafts to the leftmost molding position, raising the molding iron.

Next, the potter's wheel shaft is stopped, the forming iron is placed in the raised position, the cam shaft is stopped, and the four shafts are moved by the cylinder to the take-out position. The reversing machine connected to this device descends with the valve open, and at the lower end, the clamp simultaneously grasps the plaster in the dowel and the empty plaster mold on the conveyor, and the reversing machine ascends to the upper end. At the rising end, it reverses 1800 degrees and descends to the descending end, 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 the conveyor, and the cycle of 0 or more is automatically repeated in which the plaster powder to be molded next time is placed in the predetermined position.

(Embodiment) To explain this invention based on the drawings of the embodiment, as shown in FIGS. is mounted so as to be slidable in the left and right direction (as shown in Figure 1), and on this slide base 3, a potter's wheel shaft 5 with a dowel number fixed to its upper end is rotatably hung vertically via a four-ply shaft case 6. ! A V-belt 10 is hung between the drive pulley 8 of the rotor drive motor provided on the base 13 and the driven pulley 9 provided on the outer periphery of the dowel 4 so that the drive can rotate freely. Platform 11, Platform J!
A rotating arm 14Ti of the molding table 11 is rotatably attached to the pedestal 12 by a support shaft 13, and a slide roller 15 is attached to the rear of the rotating arm 14 (left side in FIG. 1). A balance weight 16'f is attached to the rear end of the rotating arm 14, and a rotating arm 1
A forming iron mounting arm 17 is fixed to the front part of the forming iron mounting arm 1, and a forming iron drive motor 1B is attached to the tip of this forming iron mounting arm 1f. 19 is directly connected to drive and rotate freely, so that when the rotating arm 14 is lowered, it is approximately concentric with the position at which the dowel 4 is formed on the rotary shaft 5.

On the other hand, the main cam 22 and the slide cam
3 is coaxially fixed, and the state 4-? -15 is brought into contact with the main cam 22 in a freely movable manner, and the slide ruler -26 at the rear end of the five-shaped slide arm 25 having the fulcrum 24 on the pedestal 12 is brought into contact with the main cam 22 in a movable manner. The lower end of the slide arm 25 and the rear end of the slide base 3 are pivoted 27, and the upper end is pivoted 30 to the other end of the link 2g, which has one end pivoted 28 to the four-axis nurse 6. The lower end of the link 31 is pivoted 33 to a bearing 32 fixed on the floor 1, and the center part is supported 33 on the side of the base 2.
The ends of the cylinder 35 and the ends 36 of the cylinder 35 are pivoted 37 to the middle of the link 31.

A reversing device 38, which will be described later, is mounted on the base 2 in series with the moving device 1.

To explain the reversing device 38 in detail, four slide shafts 39 are installed on the other end of the base 2, and the upper ends are connected by an upper beam 40. A slide beam 41 is slidably fitted to the SQUID shaft 39 so as to face each other, and the slide beam 41.
Between 41 and 41, an elevating frame 43rt that rotatably supports a reversing shaft 42 is installed, and a slider 4 of this elevating frame 43 is installed.
A claw base 45 that can be slidably opened and closed is attached to the claw base 45, claws 46 for clamping the dowel 4 are mounted on the inner sides of both ends of the claw base 45, and an air cylinder 47 for opening and closing is mounted in the center between the claw bases 45. Attachment: Attach the reversing motor 48i to the outer end of the reversing shaft 42.
