A guide support arm 45 is projected from the horizontal movement base 34 toward the belt conveyor 2, and a guide rod 46 for contacting the guide support arm 45 with the side surface of the tile complex a on the belt conveyor 2. Is installed.

The guide rod 46 can move forward and backward in the direction in which the guide support arm 45 projects.

The shape of the divided blades 3 and 4 is as follows.
The cutting edge 47 may be formed in a straight line, or the cutting edge 47 may be formed in a curved (circular) shape (not shown). Are mounted on the upper side and the flank 49 is mounted on the lower side.

Next, the operation of the tile dividing apparatus according to the present invention will be described.
In order to cope with the above, the dividing blades 3 and 4 are inserted into the dividing grooves e on both side surfaces of the tile composite a stopped at the tile dividing stop position P1 by the belt conveyor 2, respectively. The up and down position of 4 is adjusted in advance by operating the handles 16 and 40.

The distance between the dividing blade 3 and the dividing blade 4 is appropriately adjusted in advance according to the size of the tile composite a.

Then, the tile composite a is conveyed by the belt conveyor 2 with the direction of extrusion forming the same as the conveying direction.
When the tile complex a reaches the tile division stop position P1,
The tile complex a is detected by a sensor (not shown) and the belt conveyor 2 is controlled to be stopped, so that the tile complex a is stopped between the first and second divided blade moving mechanism units 5 and 6. Be placed.

Next, as shown in FIG. 3, when the cylinder 35 of the second divided blade moving mechanism 6 is operated to extend the rod 36, the guide rod mounted on the guide support arm 45 is extended.
46 is abutted on one side surface of the tile composite a, and the posture of the tile composite a in which the tile composite a is inclined with respect to the transport direction in the process of being transported by the belt conveyor 2 is corrected by the guide rod 46. Meanwhile, the dividing blade 4 is inserted into the dividing groove e on one side surface of the tile composite a and is brought into contact therewith, and the tile composite a is pushed by the guide rod 46 toward the first dividing blade moving mechanism 5 side. The dividing blade 4 of the fixedly arranged first dividing blade moving mechanism unit 5 is inserted and abutted into the dividing groove e on the other side of the tile composite a.

Further, by operating a pneumatic cylinder 30 to extend the rod 31 on the upper surface of the tile composite a, the roller 32 is brought into contact with the upper surface of the tile composite a, and the belt conveyor 2 is conveyed. A constant force is applied to fix the tile composite a on the road.

Next, the impact generator 43 is actuated to apply a desired number of impact forces to the tile composite a via the impact transmitting shaft 44 and the dividing blade 4, so that the dividing blade 4 is inserted and abutted. A crack is generated in the groove e to divide it into two tiles b and c.

The direction of rotation of the roller 32 is determined by the impact generator 43.
Is the same direction as the impact direction of the impact force, so even if the tile b on the upper side moves slightly with respect to the impact direction at the time of division,
Since the rollers 32 rotate in that direction, no damage occurs to the contact surface, which is the upper surface of the tile composite a.

Further, since the cylinder 30 pressing the roller 32 is of a pneumatic type, the tiles b and c
At the time of division, the tile b on the upper side acts as a cushion function against the force of moving upward.

Since the rake face 48 of the cutting edge 47 of each of the divided blades 3 and 4 is formed on the upper side of the cutting edge, the shape of the long side of the tile c on the lower side of the tile composite a is particularly lower. When the dividing blades 3 and 4 bite into the dividing groove e, they act as a force to lift the tile b upward, but do not act in a direction to press the tile c downward.

[0038]

In summary, the present invention provides two tiles b and c.
A belt conveyer 2 is provided for conveying the tile composite a formed by vertically aligning the tile composite a. Dividing grooves provided on both side surfaces of the tile composite a on both sides of the tile division stop position P1 on the conveying path of the belt conveyor 2 e, divided blades 3 and 4 which can be inserted freely are provided, an impact generator 43 is connected to the one divided blade 4, and the impact is generated in a state where the divided blades 3 and 4 are inserted and contacted in the divided groove e. Since the operation of the generator 43 is controlled, the impact force of the impact generator 43 can be reliably applied to the deep part of the division groove e, so that damage is not generated at any place other than the division, and as a result, as a final product Tiles b and c
Can be divided while preventing the deterioration of the quality of the tiles, and since the tile composite a is continuously transported by the belt conveyor 2, continuous division processing can be performed. The cost is reduced by increasing the processing speed of division and automatically continualizing while maintaining the product yield.

Further, since the rake face 48 of the cutting edge 47 of the divided blades 3 and 4 is formed on the upper side and the flank 49 is formed on the lower side, when the tile composite a is divided into tiles b and c, 4 is in a state of being cut into the divided groove e,
The rake face 48 of the dividing blades 3 and 4 only exerts a force to lift the upper tile b upward, and no force acts on the lower tile c, so that the long side of the tile c moves downward. Even when the tile c is curved, no bending stress is applied to the long side of the tile c, and the tile c can be prevented from being damaged.

Further, above the tile division stop position P1,
Since the pneumatic cylinder 30 is provided and the roller 32 is provided on the cylinder 30 so as to be rotatable in a direction perpendicular to the conveying direction of the belt conveyor 2, the upper blade b is lifted by the dividing blades 3 and 4 as described above. Even if a force is applied, the cylinder 30 is of a pneumatic type, so that the force can be reduced,
Unreasonable force does not work on tile b to prevent breakage,
Since the tile composite a can be fixed on the belt conveyor 2 by the cylinder 30 and the roller 32, the impact force from the impact generator 43 can be effectively transmitted to the tile composite a. Even if the belt conveyor 2 moves in a direction perpendicular to the conveying direction, the rollers 32 move in the same direction.
Is rotatable, so that the surface of the upper tile b is not scratched, and the practical effect is extremely large, such as preventing the quality from being lowered.
