Description

[Detailed explanation of the invention] A. Purpose of the invention (industrial field of application) This invention aims to reduce the amount of powder adhering to the surface of the tile molded product or The present invention relates to a surface cleaning device for tile molded bodies for removing burrs and the like generated during the molding process before glazing.

(Prior art) When a tile molded body is manufactured by the pressure molding method, when the raw material powder is filled into a mold for molding or when pressure molding is performed after filling, powder may be scattered and cause problems after demolding. May adhere to the surface of tile moldings. Further, burrs may be formed on the peripheral edge of the tile molded body during pressure molding, and furthermore, the burrs may collapse onto the surface due to vibration during transportation. These deposits, burrs, etc. cause unevenness on the surface of the tile molding, making it impossible to apply the glaze uniformly, and causing poor product quality such as uneven color and separation of the glaze from the base after glazing. becomes. Therefore,
Before glazing, it is necessary to clean the surface of the tile molded body to remove deposits, burrs, etc., and to eliminate unevenness, but there was no suitable equipment for this purpose.

(Problems to be solved by the invention) As mentioned above, because there was no suitable device to remove deposits, burrs, etc. from the surface of the tile moldings,
Conventionally, a worker is placed next to the transportation path for the tile molded bodies before glazing, and the worker cleans the tile molded bodies, or cleans the tile molded bodies that are unsuitable for glazing as is. were removed by visual inspection.

In either case, manpower is required to maintain the quality level of the product, and the burden placed on the worker is heavy, resulting in low work efficiency and poor yield.

B. Structure of the invention (means for solving the problem) In order to remove powder adhering to the surface of the tile molded object or burrs generated during the molding process before glazing, the upper surface of the transport path of the tile molded object is A surface cleaning device for tile moldings was installed. The cleaning device includes a support body installed above the conveyance path surface of the tile molded body, and a cleaning member that is attached to the support body so as to be slidable in the conveyance direction of the tile molded body and whose lower part is formed into a plate-shaped body. , an angle holding means for holding the cleaning member in an inclined position at a predetermined angle with respect to the conveying direction of the tile molded body, and separating the lower end of the cleaning member from the conveyance path surface of the tile molded body at a height position less than the thickness of the tile molded body; Become.

Further, an appropriate load is applied to the cleaning member in order to adjust the pressing force depending on the surface properties of the tile molded body.

(Function of the invention) In the cleaning device according to the invention, the cleaning member is swingably attached, and the angle holding means allows
The lower end of the tile molded body is maintained at a height less than the thickness of the tile molded body from the transportation path surface of the tile molded body. Therefore, the tile molded body being conveyed hits the cleaning member and causes the cleaning member to swing upward. As the tile molded body moves, the lower end of the cleaning member rubs the surface of the tile molded body with an appropriate pressing force to remove adhering powder, burrs, and the like. Since the cleaning member is swingably attached, cleaning work can be performed continuously without interfering with the conveyance of the tile molded bodies. Furthermore, since the angle of the cleaning member is kept constant for tile molded bodies of the same thickness, the pressing force exerted on the surface of the tile molded body is kept constant. Moreover, since the cleaning member is maintained in a non-contact state with the conveyance path surface, the lower end of the cleaning member does not come into contact with the conveyance path surface immediately after the tile molded body passes, and is not worn out due to friction therewith.

(Example) FIGS. 1 to 3 show an example of a surface cleaning device for a tile molded body according to the present invention.

The support body 1 is suspended above the conveyance path surface 2 from support columns 3 erected on both sides of the conveyance path surface 2 via bolts 4 as height adjustment mechanisms. The cleaning member 5 consists of a base 5a swingably supported on the support 1 by a hinge 6, and a cleaning plate 5b attached to the lower end of the base 5a, and a weight 7 of an appropriate weight is attached. has been done. The cleaning plate portion 5b is a thin metal piece with a thickness of about 0.5 mm made of a highly elastic, wear-resistant, and corrosion-resistant material such as phosphor bronze, and its width is the same as that of the tile molded body 8 to be cleaned. It is determined according to the width. The weight of the weight 7 is appropriately selected depending on the hardness of the tile molded body 8, the surface condition, etc., so that the surface can be sufficiently cleaned without damaging the surface.

The cleaning member 5 is rotated by the angle holding means 10.
maintained at a constant angle. This angle holding means 10
consists of a fixture 11 attached to a support 1 and a movable bolt 12 screwed onto the fixture 11, and supports the cleaning member 5 at the tip of the movable bolt 12 to maintain it at a desired angle. .

By operating the angle holding means 10 and the bolt 4 for adjusting the height of the support 1,
While maintaining the cleaning member 5 at a desired angle, the lower end can be maintained in a non-contact state from the conveyance path surface 2 at a height less than the thickness of the tile molded body 8.

The cleaning work of the surface of the tile molded body according to this embodiment is performed as follows.

The tile molded body 8 that has been conveyed is transferred to the cleaning plate section 5
b, and pushes up the cleaning member 5 which is swingably supported, and moves with the lower end of the cleaning plate part 5b in contact with the surface. At this time, since a weight 7 having an appropriate weight is attached to the cleaning member 5, the lower end of the cleaning plate portion 5b is attached to the tile molded body 8.
Rub the surface with moderate pressure to remove deposits, burrs, etc.

By the way, the cleaning plate portion 5b is slightly abraded due to the long-term cleaning operation of the surface 8a of the tile molded body. Therefore, the length of the cleaning plate part 5b becomes short, and the lower end does not reach the tile molded body surface 8a, making cleaning impossible, or the cleaning plate part 5b becomes tile molded body surface 8a during cleaning work.
If the angle of inclination becomes large, an appropriate cleaning effect cannot be obtained. Even in such a case, if the cleaning device of this embodiment is used, the height adjustment bolt 4
and/or by operating the angle holding means 10 to bring the lower end of the cleaning plate portion 5b closer to the conveyance path surface 2,
It is possible to continue cleaning work.

Furthermore, even if the thickness of the tile molded body differs depending on the type, the cleaning device of this embodiment can
It is possible to adapt so that a predetermined cleaning state can be maintained. For example, when transferring work from thin tile moldings to thick tile moldings,
When you want to maintain the inclination of the cleaning plate at a constant angle,
The height of the support may be increased by an amount corresponding to the increased thickness. Of course, the opposite is also possible.

Furthermore, depending on the molding conditions of the tile molded product, the surface condition will vary, but if the amount of powder adhering to the surface is excessive or firmly adhered, or if there is a large amount of burr. If the surface of the tile molded body is scraped by the cleaning plate, the pressing force must be increased. In such a case, the objective can be achieved not only by increasing the weight of the weight, but also by increasing the angle of inclination of the cleaning plate with respect to the surface of the tile molded body.

On the other hand, when dealing with a tile molded body with a relatively soft surface, the pressing force applied to the tile molded body surface can be reduced by reducing the inclination angle of the cleaning plate. The same effect can be obtained as reducing the weight of .

In the above embodiment, the cleaning device is provided with an angle holding means having an angle adjustment function as well as a support height adjustment mechanism, but the invention is not limited to this. FIG. 4 and FIG. 5 show another embodiment in which an angle holding means for supporting the cleaning member at a certain angle and a support height adjustment mechanism are provided;
and one provided only with an angle holding means for the cleaning member,
Each is shown below.

The device for cleaning the surface of a tile molded object according to the present invention includes:
In addition to using a single unit, it is also possible to install a plurality of units in parallel, as shown in FIG. 6, depending on the equipment situation.

C. Effect of the invention The device for cleaning powder and burrs adhering to the surface of a tile molded body according to the present invention efficiently removes deposits, burrs, etc. on the surface of a tile molded body before glazing, and eliminates unevenness caused by unnecessary materials on the surface. Since it becomes possible to apply the glaze uniformly, it is possible to prevent uneven coloring and separation of the glaze and the base material after glazing. The cleaning member is swingable, so even if there is some variation in the thickness of the tile moldings, the lower end of the cleaning member can be brought into contact with the surface of each tile molding to ensure cleaning. can be done. The execution of cleaning work is
Since the conveying force of the tile molded body is used, no special power source is required. Therefore, the structure of the device can be extremely simplified without causing an increase in cost. By holding the cleaning member in an inclined position in advance, the swinging angle of the cleaning member is small compared to the case where the cleaning member is simply suspended from a support body, and therefore,
The force required to convey the tile molded body to swing the cleaning member is small. Therefore, the present invention is also applicable to lightweight tile molded bodies. Furthermore, there is no need to stop the conveyance of the tile molded bodies, and cleaning work can be carried out continuously without the need for manpower, which improves production efficiency. Furthermore, since a means is provided to maintain the lower end of the cleaning member in a non-contact state with the conveyance path surface, wear on the cleaning plate is extremely reduced.
Therefore, there is almost no need to interrupt the work to replace cleaning members, etc., and continuous operation can be stably performed for a long time. Further, since localized abrasion and uneven abrasion do not occur, there is no possibility of damaging the surface of the tile molding during cleaning or leaving uncleaned areas.

In short, by using the apparatus for cleaning powder and burrs adhering to the surface of a tile molded body of the present invention, the glaze of the tile molded body becomes uniform, and a high-quality product can be stably supplied at a low cost.
