Abstract

PURPOSE:To aim at improvements in operation efficiency, by feeding a turning gear with tiles at regular intervals, while constituting this turning gear so as to make it go up, rotate, go down, turn round and put it back to a conveying device, and making it accurately turnable at the specified angle, in case of a turning device for tile manufacturing process use. CONSTITUTION:When a tile T is transferred to a turning range R by a feed belt 5, an interval to a succeeding tile T' is widened because a conveying belt 4 in the turning range R is speedier than the feed belt 5. When a photoelectric switch 3 operates, a timer (unillustrated herein) is set in motion, stopping the succeeding tile T' at a stopper 2. The tile T is mounted on a turning gear 1, going up with a cylinder 1c and, after a rotary cylinder 1b is rotated by 90 deg., again it is made to go down, then the tils T is put back to the conveying belt 4. With this belt, the tile T is conveyed again, while the succeeding tile T' is conveyed to the turning range R as the stopper 2 is released. With this constitution, the tile is efficiently turnable.

Description

DETAILED DESCRIPTION OF THE INVENTION A.Objective of the invention (industrial application field) The present invention provides a method for removing paris generated after tile molding and removing excess glaze adhering to the side surface of the tile after glazing. The present invention relates to a tile turning device and a tile turning method used in processes that require tile turning, such as finishing and changing direction when a conveyance path is bent.

(Prior art and its problems) During the manufacturing process of tile products, it is often necessary to rotate the tiles during transportation and change their orientation. For example, when molding tiles, pressure forming When it comes to law, the tie obtained.

At the same time, cracks and the like often occur on the periphery of a molded object (hereinafter simply referred to as tile). In addition, in the glazing process, glaze is applied to the top surface of the tile, but spraying,
No matter which method of glazing is used, such as curtaining, dipping, or brushing, more or less excess glaze will adhere to the sides of the tile. Therefore, it is necessary to remove the glaze that has formed on the periphery of the tile and the excess glaze that has adhered to the side surface of the tile. Finishing equipment was used. 41st D (
A) is for removing the flakes generated on the upper edge of the tile, and (B) is for removing excess glaze adhering to the side surface of the tile. By the way, in order to finish the entire circumference of the side, it was necessary to rotate the tile midway through and change its orientation.

In other words, the finishing device can only process one pair of opposing sides out of the four sides at a time, so the tile had to be rotated 90 degrees during transportation to finish the remaining sides. Until then, there was no suitable self-imitation device.

Configuration of the Invention (Means for Solving Problems) The present invention provides a rotating device that holds the tile in a non-contact state with respect to the transport path surface and changes the orientation of the tile in order to change the orientation of the tile. and means for sequentially feeding the tiles at predetermined intervals to the rotating device.

In addition, in order to improve work efficiency, there is a process in which tiles are fed to a rotating device at predetermined intervals, and the tiles fed to the rotating device are held in a non-contact state with respect to the conveying path surface to ensure orientation of the tiles. Appropriate control means using timers, limit switches, photoelectric switches, proximity switches, etc. are used to perform the process of changing the tile, returning the turned tile to the conveyance path, and returning the rotating device to the initial state of receiving tiles. It was decided to switch automatically.

(Operation of the Invention) By using the above means, the tiles can be rotated continuously and accurately by a predetermined angle. Also,
Since each process is automatically switched by appropriate control means, work efficiency is improved.

(Example) FIG. 1 is a partially omitted perspective view showing an example of a tile self-remodeling device according to the present invention.

The tile self-printing device includes a rotating device 1 for changing the orientation of the tiles T, a tile stopper 2 for sequentially feeding tiles to the rotating device 1 at predetermined intervals, a photoelectric switch 3 for detecting the tile position, and the like.

Tiles during the manufacturing process are not necessarily transported in an orderly manner. That is, sometimes it is conveyed continuously, sometimes it is intermittently conveyed, and sometimes it is conveyed at different intervals. In order to sequentially turn the irregularly transported tiles one by one, each tile must have an appropriate spacing. The required spacing depends on the tile dimensions,
In this embodiment, the required spacing is given to each tile by using the tile stopper 2 and the photoelectric switch 3. The tile stopper 2 is not necessarily required if the tile spacing can be set to a required size or more on the conveyance path depending on the equipment conditions.

In the tile conveyance path, the area where the rotating device 1 is installed (
The conveyor belt 4 in the rotation area R (hereinafter referred to as rotation area R) is faster than the feed belt 5 and delivery belt 6 in the areas before and after it (hereinafter referred to as the feed area S and the delivery area Q). Therefore, when the tile T is transferred from the feeding area S to the rotation area R, the distance between it and the succeeding tile T' is expanded due to the speed difference. The conveying speed in the rotation area R may be about twice that of the feeding area S, but this value is changed as appropriate depending on the amount of tiles to be processed.

The rotating device 1 is composed of a rotary cylinder 1b equipped with a table 1a for supporting tiles, and a cylinder IC for raising and lowering the rotary cylinder 1b. In this embodiment, the rotary cylinder 1b and the cylinder IC each receive compressed air. Driven by supply. The rotational speed of the rotary cylinder 1b and the lifting speed of the cylinder IC are controlled by adjusting the supply amount of compressed air using a speed controller, etc., but care must be taken to prevent the tiles from shifting or popping out. , it is necessary to avoid rapid acceleration or deceleration. It is desirable to attach rubber or the like to the surface of the table 1a to prevent the tiles from slipping, or
A suction mechanism may be provided to attract and hold the supported tiles. Note that the shape of the table 1a is arbitrary as long as it can support the tiles stably.

For example, if a disk-shaped table is used, the diameter is 1
The 20-node table allows for the reversal of tiles up to 300km square.

The tile stopper 2 is provided near the end of the feeding area S, and the photoelectric switch 3 for tile detection is provided near the starting end of the rotation area R. In this embodiment, as the tile stopper 2, an air cylinder was used, in which a plate 2a having a width equal to or slightly narrower than the tile width was attached to the tip of the cylinder. Further, although the photoelectric switch 3 is used for tile detection, it is of course possible to use other detection devices.

FIG. 2 is an explanatory diagram showing a tile self-printing method using the tile self-printing device. In this embodiment, the switching of each process is controlled over time by a timer, but this may also be done by detecting the position of the tile using a photoelectric switch, a limit switch, a proximity switch, or the like.

When the tile T is transferred to the rotation area R by the feeding belt 5, since the conveying belt 4 in the rotation area R is faster than the feeding belt 5, the interval between the tile T and the succeeding tile T' increases due to the fast feeding. be done. At the same time as the tile T enters the rotation range R, the photoelectric switch 3 provided near the starting end of the rotation range R detects the tile and starts the operation of the timer. [
Figure 2 (A)] After a predetermined time has elapsed since the tile was detected by the photoelectric switch 3, that is, before the subsequent tile T' reaches a predetermined stop position, the tile stopper 2 is raised and the subsequent tile T' is rotated. Prevent entry into area R. [FIG. 2(B)] On the other hand, when the tile T fed into the rotation area R reaches a predetermined position, the cylinder IC of the rotation device 1 is raised. The tile T is lifted up while being supported by the table 1a at its substantially central portion, and brought into a non-contact state with the conveyor belt 4. [FIG. 2(C)] When the tile T reaches the highest point, the rotary cylinder ib is rotated 90 degrees. After the direction change is completed, the cylinder IC is lowered to return the tile T onto the conveyor belt 4. [
Fig. 2 (D) to (E)] At the same time as the cylinder lc returns to the initial position, the rotary cylinder lb is returned to the initial state, the tile stopper 2 is lowered, and the next tile T' is fed to the rotation range R. do. [FIG. 2(F)] FIG. 3 shows a case where the tile self-imprinting device is installed on a side finishing line after glazing tiles. Excess glaze inevitably adheres to the sides of the tile T glazed with the glaze spray 10 or the like. Two side finishing devices 11a and llb for removing the glaze attached to the side surfaces are installed on the conveyance path at an appropriate interval, and the two side finishing devices 1
Between 1a and llb, a rotating device 1, a tile stopper 2,
A self-reproducing device consisting of a photoelectric switch 3 etc. is provided.

A pair of side surfaces are first finished by the side surface finishing device 11a at the front stage. Thereafter, the tile is rotated 90 degrees by the rotation device 1, and passed through the side surface finishing device llb at the subsequent stage to finish the remaining side surfaces.

If the tile self-modeling device and the tile self-modeling method according to this embodiment are used, the tile self-modeling device and the tile self-modeling method can be used not only for normal square or rectangular tiles, but also for many types of tiles, without making almost any changes to the tile self-modeling device and self-modeling method. It is possible to accurately rotate square tiles and other irregularly shaped tiles by the required angle. For example, if an equilateral triangular tile is used, it is necessary to rotate it by 60 degrees to finish the sides. With the tile self-imitating device according to the example, it is possible to deal with this problem with an extremely small adjustment of changing the amount of compressed air supplied to the rotary cylinder.

EFFECTS OF THE INVENTION The present invention allows tiles to be rotated continuously and accurately without causing any error in the rotation angle in a process that requires reorientation of tiles. Moreover, since the rotation angle, rotation direction, rotation speed, etc. can be easily changed, even if the tile size, shape, etc. change, it is easy to change the direction accurately. Therefore, regardless of the type of tile, the finishing treatment can be applied to the entire periphery of the tile without deviation, which not only improves the quality of the product but also makes it possible to manufacture a variety of tile products, which is appealing to customers. Can meet various demands.

In addition, we have provided a means to automatically switch between each process, so
It is possible to save manpower and improve work efficiency and yield.
