Description

[Detailed description of the invention] This invention connects abrasive materials placed opposite to the peripheral edge of the tile raw material to a vibrator while the tile raw material is conveyed from the molding machine to the sheath filling device. The present invention relates to a finishing device for tile raw material in which molding burrs on the circumferential edge are removed by vibration of an abrasive.

FIG. 1 is a diagram showing the finishing process from forming the tile raw material to finishing it in the sheath filling 1 using a general finishing device.

As shown in FIG.
Burrs 3 are generated on each circumferential side edge of the front and back surfaces, and these burrs 3
If the number of tiles is up to 1, it may be damaged in the subsequent process or may damage other tiles, and the appearance may be poor, resulting in a reduction in product value.

For this reason, conventionally, the burr 3 has been removed by a worker using sandpaper, or the burr 3 has been automatically removed using a device shown in FIG.

The former case by workers is extremely primitive;
Since there are problems with productivity and cost, the latter method shown in FIG. 1 has usually been used more frequently.

In FIG. 1, a conveyance path consisting of a belt conveyor, etc., which conveys the tile green material 2 formed by the 4Fi molding machine 1 by a sheath filling device 51, and 6 to 8 are the forming burrs 3 disposed in the middle of the conveyance path 4. They are a removing device and a reversing device.

The removing device 6 removes the burrs on both opposing diagonally upper sides of the tile blank 20, then the reversing device 7 rotates the tile blank 2 horizontally by 90', and the removing device 8 removes the remaining burrs on the opposing diagonally upper sides. I try to remove burrs from the edges.

Reference numeral 9 denotes a brushing roll for brushing off dust from the tile raw material 2.

As shown in FIG. 3, the conventional burr removal devices 6 and 8 have springs 12 mounted diagonally above both opposing sides of the tile blank 2 that has been conveyed by a conveying device consisting of belts 10a and 10b. The structure is such that an abrasive material (sandpaper, mesh paper, etc.) 13 is placed therein and is fixed to a fixed frame 16 via a spacing adjustment rod 14 and an arm 15.

Reference numeral 17 denotes a support frame for the belt holder 17, which is a belt holder for preventing bending of the belt holder 10a, 10b, and 18/li.

Similarly, a plurality of tile blanks 2 are simultaneously conveyed in parallel and processed.

The burrs 3 on the tile raw material 2 are ground away by the abrasive material 13 being pressed against the burrs 3 on the opposite diagonally upper side edges, and the tile raw material 2 being conveyed.

However, with this conventional device, it is difficult to adjust the pressing force of the abrasive material 13, and if it is too strong, the progress of the tile green substrate 2 is blocked, and the green substrates that are sequentially conveyed collide with each other and damage each other. There were drawbacks such as damage caused by falling or falling from the conveyance path.

Even if the pressing force of the abrasive material 13 is appropriate, as shown in FIG. There is a disadvantage that a large pressing force is applied, and the portion is largely scraped off.Furthermore, if the pressing force is too weak, the burr 3 cannot be removed.

The reversing device 7 is constructed as shown in FIGS. 4 and 5, and is adapted to reverse the tile blank 2 90' in the horizontal direction.

In the apparatus shown in FIG. 4, when the tile raw material 2 comes to the position of the rotating shaft 19 that can be raised and lowered, the shaft 19 pushes up one side of the tile raw material 2 and stops that part at the same time. bell) raised from 10a, bell)
Rotate it in the direction of the arrow in the same figure by the conveying force of 10b,
The raw material 2, which does not rotate properly, is corrected using a shaft 20 for correction, and then carried into the guide plate 11.degree. 11 and conveyed.

On the other hand, in the one shown in FIG. 5, the rotation shaft 19 is fixed and a conveyance bell is placed in front of it.
A roller 21 is provided to push up one of the tile raw materials 2, and one side of the tile raw material 2 is placed on the rotating shirt 19.The rest is carried out in the same manner as shown in FIG.
was rotating.

In this way, the reversing device 7 is located between the deburring devices 6 and 8 [6
Then, the tile raw material 2 from which the burrs 3 on both opposing upper side edges have been removed by the removing device 6 is turned over 90' horizontally, and the remaining burrs 3 on the opposing upper side edges are removed by polishing with the removing device 8. It is something that makes you

Thereafter, the tile raw material 2 from which the burrs 3 have been removed is passed through a brushing roll 9 to remove dust on the tile raw material, and then supplied to the sheathing device 5.

However, as mentioned above, the conventional paris removal devices 6 and 8 have many drawbacks that should be improved.

The present invention improves and eliminates the above-mentioned drawbacks of the conventional tile raw material finishing device, by disposing an abrasive material opposite to the peripheral edge of the tile raw material, and using the holding arm and the abrasive material. It is connected to a vibrator disposed on a fixed frame of the conveyance path via a continuous frame and a connecting rod, and uses the vibration of an abrasive to remove burrs after forming the tile base material.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

FIG. 7 shows the case where the present invention is applied to a line where five tile blanks 2 are simultaneously molded using the molding machine 1 shown in FIG.
FIG. 2 is a perspective view showing the entire parity removing device 21. FIG.

Similarly, the conveyance guide plate for the tile raw material 2 is omitted.

In the same figure, 22 is a side frame 23 on the left and right sides of the mount,
It is a gate-shaped fixed frame constructed between 23 spaces.

A vibrator 25 is fixed on the fixed frame via an elastic body 24 for preventing H1 vibration.

The vibrator 25 has fixed frames 2 on the left and right sides of the vibrator 25.
The connecting rods 27 and 27 are inserted freely through the through holes 26 and 26 formed in the connecting rods 2 and 27, and a connecting frame 28 in the form of a flat plate is fixed to the tip end of the connecting rods 27 and 27, respectively.

The continuous frame 28 has holders (bearing holders, etc.) 29 fixed on both ends thereof in order to prevent the vibration from shifting and twisting across the left and right ends in the figure when the vibrator 25 vibrates. The guide rod 30 protrudes from the lower surface of the fixed frame 22 and fits into the guide rod 30 .

It is equipped with a so-called lateral shift prevention mechanism.

The front end surface (the front end surface in the tile raw material conveying direction) 28aKu of the continuous frame 28, and the burr on the upper side opposing circumferential edge of the tile raw material 2 corresponding to each of the FJI tile raw materials 2 being conveyed. Abrasive materials 31, 31 for removing 3 are fixedly installed in a height-adjustable manner.

The abrasive materials 31, 31 are fixed to the tip of a holding arm 32 which is bent into a U-shaped cross section, and the upper end plate of the arm 32 is attached to the front end surface 28a of the continuous frame 28 via a support rod 33 and a fastening metal fitting 34. Fixed.

Further, on the rear end surface 28b of the continuous frame 28, abrasives 35, 35 for removing the burr 3 on the lower side opposing circumferential edge of the tile raw material 2 are fixedly installed in the same manner as described above.

36, 36 are press rollers for preventing the tile raw material 2 from lifting up during the operation of the abrasive materials 35, 35, and are rotatably supported by a connecting member 37, and the connecting member 37 is connected to the side frame 23, 23 of the pedestal. The rack is fixed to a frame 38 passed between them.

Similarly, when the abrasive material 31.31U is seen from the conveying direction side of the tile raw material 2, the abrasive materials 35.35H are fixed so that they form an inverted . Fixed.

In addition, the front and rear ends of both polishing materials 31.31 and 35.35 are
Each of them is curved and expanded outward so that the tile raw material 2 can be easily transported.

Next, a description will be given of an operation mode for removing burrs 3 from the tile raw material 2 by the embodiment apparatus 21 configured as described above.

The tile raw material 2 is a square with a side length of 109 mm and a thickness of 5.1 mm, the vibration frequency of the vibrator 25 is 50 cycles, and the stroke is 0.2 to 0.3 mm. Suppose that

Tile raw material 2 is bell) 10 a t 10 b
Therefore, when the abrasive materials 31, 31 are transported in the position casing, the burrs 3 are uniformly formed on the entire upper circumferential edges of the tile raw material 2 due to the vibrations caused by the above-mentioned cycles and strokes of the abrasive materials 31, 31. Grinding is removed by pressure contact.

In this case, the belt receiver 17 and the support frame 18 serve to prevent the tile substrate 2 from shifting downwards.

In this way, the tile base material 2 from which the burrs 3 on the circumferential edges of the opposing upper sides have been removed is then moved to the presser rollers 36, 36.
and bells) 10a, 10b, and the next vibration of the abrasives 35, 35 removes the burrs 3 on the entire circumferential edges of the opposing lower sides with a uniform pressing force.

After that, as in the conventional case, the tile substrate 2 is inverted horizontally by 90° using the inverting device 7 shown in FIG.
The remaining upper and lower opposing circumferential edge burrs of the tile raw material 2 may be ground away using the same device as the device 21 of the above-mentioned embodiment installed behind the reversing device 7.

Armor, tile raw material 2, and abrasive materials 31, 31 and 32.3
2, the stroke of the vibrator 25, the vibration cycle, and the vibration direction, etc., should be determined as appropriate by taking into account the material of the tile raw material 2, the average size of burrs during molding, etc. do it.

In this way, the present invention arranges the abrasive material opposite the peripheral edge of the tile raw material, and transfers the abrasive material onto the fixed frame of the conveyance path via the holding arm, the connecting frame, and the connecting rod. The abrasive material is connected to a vibrator installed in the tile material, and the vibration of the abrasive material removes molding burrs after forming the tile material material, so it is no longer necessary to delicately adjust the pressing force of the abrasive material to the tile material material, unlike conventional methods. It's unnecessary.

In addition, a uniform pressing force can be obtained over the entire circumferential edge of the tile, which improves quality and prevents accidents such as clogging, collision, and falling of the raw tile material in the conveyance path.

Since the abrasive material is constantly vibrating, there is no fear that dust after grinding will fall due to vibration and clogging, and it can be used for a long time.

Furthermore, since it is a vibration method, there are advantages such as the overall length of the abrasive material being shorter than the conventional biasing method using a spring.
