The upper bell crank 23 is biased to cause the abutting nut 46 to abut against the receiving member 47. In this state, the vacuum suction body 31 is
As shown in the figure, the tile 2 of the lower die 5 of the press device 1
It is set to be located at a height that allows it to fit between the upper mold 4 and the upper mold 4. The magnitude of the biasing force of the spring 52 is such that when the main body 19 is moved by the drive device 24, the spring 52 is not stretched by running resistance and the posture of the upper bell crank 23 is maintained in the state shown in FIG. When the movement of the main body 19 is stopped by the stopper described later, the upper bell crank 23 is rotated by the force of the drive device 24 as shown in FIG. 4, and the vacuum suction body 31 is lowered. It is set to A stopper 53 stops the forward movement of the main body 19 at a predetermined position, and is attached to the lower end of the support frame 14 so as to receive the upper end 19a of the main body 19. This stopper 53 is provided with a cushion mechanism to soften the impact when it is stopped, but this cushion mechanism may not be provided.
This stopper 53 is positioned so as to receive the main body 19 when the one end 23a of the upper bell crank 23 is moved near the forward end and the vacuum suction body 31 is moved directly above the tile 2 of the forming section 1a. There is. 54 is a vacuum generation blower fixed on the lifting frame 16, and 55 is the lifting frame 16 as well.
With the switching valve fixed on the top, this switching valve 5
5 to the blower 54 and the vacuum adsorbent 31.
and the ventilation chamber 35a are connected by hoses 56 and 57. This switching valve 55 applies suction force to the suction cup 37 when the vacuum suction body 31 is moved to the forward end, and then releases the suction force of the suction cup 37 when the vacuum suction body 31 is returned above the round belt 12. It's summery. Reference numeral 58 denotes a detector for detecting that the crank 26 of the drive device 24 has been moved to the rearward end, and is comprised of a limit switch, a proximity switch, or the like. This detector 58 is adapted to stop the rotation of the brake motor 25 in response to its detection signal. Reference numeral 59 is a safety device for preventing the lift frame 16 pulled up by the cylinder 18 from falling, and is configured to lock the lift frame 16 in the raised position. 60 is the above safety device 5
The lifting frame 16 can be unlocked by tilting the operating lever 9. In FIG. 5, F is the upper bell crank 23 and the spherical joint 28 when the crank 26 is at point B.
G indicates the position of the connection point at points C and E, H indicates the position of the connection point at point D, and L indicates the size of the longitudinal movement stroke of the main body 19. ing.

In the case of the above structure, when the tile 2 is to be taken out from the press device 1, the operation lever 60 is operated to release the lifting frame 16 from the safety device 59, and then the cylinder 18
The piston rod 18a is lowered by hydraulic or pneumatic pressure to lower the main body 19 to the working position shown in FIG. At this point, the rotation of the rotating shaft 25a of the brake motor 25 is stopped, and the crank 26 is stopped at the rearward end position B shown in FIG. Therefore, the vacuum suction body 31 is lifted above the round belt 12 by the other end 42b of the lower bell crank 42, as shown in FIGS. 1 and 3. In this state, when the press device 1 pushes up the molded tile 2 with the lower mold 5 and makes the tile 2 ready for removal, the rotating shaft 2 of the motor 25 with a brake is
5a is rotated in the direction of the arrow in FIG.
6 in the same direction. This rotation of the crank 26 pushes one end 23a of the upper bell crank 23 toward the press device 1, and at this time, the upper bell crank 23 has sufficient attachment to overcome the running resistance of the main body 19 and lift the vacuum suction body 31. Since the force is applied by the spring 52, the main body 19
is moved forward while holding the vacuum suction body 31 in the raised position, whereby the vacuum suction body 31 enters between the tile 2 on the lower mold 5 and the upper mold 4. Then, when the crank 26 is rotated to point C in FIG. The main body 19 is prevented from moving forward by contacting the stopper 53, and the switching valve 55 is operated to switch the suction cup 37 of the vacuum suction body 31.
Air suction begins. Since the crank 26 continues to rotate after that, until the crank 26 is rotated to the forward end position D, the upper bell crank 23 is rotated counterclockwise by overcoming the biasing force of the spring 52 as shown in FIG. Rotate to. The rotation of the upper bell crank 23 also causes the lower bell crank 42 to rotate, and as a result, the vacuum suction body 31 is released from being lifted by the lower bell crank 42 and is lowered by its own weight, so that the suction cup 37 of this vacuum suction body 31 is lowered. It is pressed against the upper surface of the tile 2 on the mold 5. Further, as described above, each suction cup 37 is pressed against the top surface of the tile 2 and is slightly elastically deformed, and when the tip edge of each suction cup 37 is fully contacted with the top surface of the tile 2, the parallel link 32
b comes into contact with the stopper bolt 39, and further lowering of the vacuum suction body 31 is prevented. Therefore, it is possible to prevent an unreasonable load from being applied to the suction cup 37, and to reduce damage to the suction cup 37. When each suction cup 37 is pressed against the upper surface of the tile 2 as described above, each suction cup 37 reliably attracts the tile 2 because a suction force is applied to the suction cup 37 . Then crank 26
Until the upper bell crank 23 is rotated to point E, the upper bell crank 23 is rotated back by the biasing force of the spring 52.
As a result, the lower bell crank 42 is rotated back and the vacuum suction body 31 is raised. Therefore, sucker 3
The tile 2 adsorbed by the mold 7 is also lifted up in a horizontal state, and in this case, the tile 2 is not moved laterally on the lower mold 5, so that damage to the tile 2 can be reduced. Thereafter, when the crank 26 is rotated toward the rearward end position B, the main body 19 is moved backward while holding the vacuum suction body 31 in the raised position, and as a result, the tile 2 attracted to the vacuum suction body 31 is It is moved slightly above the round belt 12 of the tile conveyor 9. When the crank 26 is moved to the backward end position B, the detector 58 detects the crank 26 and stops the rotation of the brake motor 25, and at the same time, the switching valve 55 is switched to release the suction force of the suction cup 37. As a result, the tile 2 that was attracted to the suction cup 37 is released and the rotating round belt 12
The material is dropped onto the surface and transported to the next process by the rotation of the round belt 12. By sequentially repeating the above operations, the tiles 2 formed by the press device 1 are taken out one after another into the receiving section 8. Note that when the tile 2 is not to be removed, the piston rod 18a of the cylinder 18 is raised to raise the elevating frame 16, and the main body 19
and the vacuum suction body 31 so that they do not interfere with other work.

FIG. 6 shows a different embodiment of the present application, in which a vacuum suction member 31e is connected to the other end 42be of the lower bell crank 42e in a suspended state, and the lower bell crank 42e is biased by a spring 52e. This is what I did.

It should be noted that the same reference numerals as those in the previous figure are appended with an alphanumeric letter "e" for parts that are functionally the same or equivalent to those in the previous figure, and redundant explanations are omitted.

As described above, in the present invention, by moving the main body 19 back and forth by the drive device 24, the vacuum suction body 31 is first moved forward from the receiving part 9 to the press device 1. It can be lowered, and then raised to its original height and then moved back to the receiving section 9. Moreover, the vacuum suction body 31 attracts the tile 2 when it is moved to the press device 1, and then moves it back to the receiving section 9. 9, the tile 2 is released, so when the tile 2 is taken out from the press device 1 to the receiving section 9, the vacuum suction body 31 is advanced above the tile of the press device 1, and then the tile 2 is released. The tile 2 can be taken out to the receiving part 9 by being lowered to attract the tile 2 to the vacuum suction body 31, and then the vacuum suction body 31 is raised and moved backward to the upper part of the receiving part. This has the advantage of reducing damage caused by 2.

Further, even if the vacuum suction body 31 is moved forward, lowered, raised, and retreated as described above, the movement of the vacuum suction body 31 is controlled by one end of the upper bell crank 23 provided at the upper position of the main body 19. 23
Since this can be done by pushing and pulling a by a predetermined amount, the operation of the drive device 24 for moving the vacuum suction body 31 can be simplified, and the structure of the drive device 24 can be simplified. This has the effect of ensuring the operation of the drive device 24.
