The end 55 is connected to the movable body 54 of the driving means 6 via an absorbing means 56 for absorbing the extension of the cable inner 8. The cylinder device 51 moves the piston rod 52 in the C and D directions by high-pressure air supplied and discharged to an air supply / discharge port 62 formed in the cylinder main body 61. One end of the cable outer 7 on the drive means 6 side is fixed to a flange 64 fixed to the cylinder main body 61 with a screw 63 or the like by a hollow metal fitting 65 and a nut 66 screwed to the hollow metal fitting 65. In this example, the hollow metal fitting 65 is fitted into the through hole 67 with the lateral opening 68 formed in the flange 64, and cooperates with the nut 66 to clamp the flange 64, thereby forming the cable outer 7. Since one end on the driving means 6 side is fixed, the nut 66 is loosened, and the fixing of the flange 64 by the hollow metal fitting 65 and the nut 66 is released. Through the flange 64.
[0021]
The absorbing means 56 is mounted on a through hole 71 formed in the plate-shaped movable body 54 so as to be slidable in the C and D directions, and a cylindrical portion 73 protruding from the through hole 71 on one surface 72 of the movable body 54.

The other end 55 of the cable inner 8 protrudes from the adjustment bolt 80 through the respective hollow portions of the nut 74, the joint fitting 77 and the adjustment bolt 80, and is locked by the stopper 81. The absorbing means 56 absorbs the extension of the cable inner 8 by always pulling the other end 55 of the cable inner 8 in the direction D by the elastic force of the coil spring 78. The movement of the movable body 54 in the C and D directions is relatively slidably extended through a through hole 91 formed in the movable body 54, and is guided by a guide rod 92 having one end fixed to the flange 64. It is supposed to be. 93 is a stopper.
[0022]
In this example, the elastic force of the coil spring 78 is set to be always larger than the elastic force of the coil spring 41, and the moving force of the air cylinder device 51 in the D direction with respect to the movable body 54 is set to this value. It is set to be sufficiently larger than the total elastic force of the opposing coil springs 41 and 78.
[0023]
As shown in FIG. 4, the apparatus 1 used for moving the object configured as described above, for example, each of the conveyors 101, 102, 103, and 104, The object 100 conveyed from the conveyors 101 to 104 is selectively pushed out by the operation head 4 arranged in the vicinity, and is operated so as to be placed on the other conveyors 105, 106, 107 and 108. That is, in a state where high-pressure air is supplied from the air supply / discharge port 62 to the cylinder body 61, the piston rod 52 extends most out of the cylinder body 61, and therefore, the cable inner 8 is pulled most toward the drive means 6 side. The movable body 12 of the operation head 4 is in a state of being inserted most into the hollow portion 21 of the hollow body 22 against the elastic force of the coil spring 41. In this state, when the high-pressure air in the cylinder body 61 is discharged from the air supply / discharge port 62, the pulling force of the cable inner 8 toward the driving means 6 is released, and as a result, the extension elasticity of the coil spring 41 is reduced. The cable inner 8 is urged by the force to pull the cable inner 8 toward the operation head 4, and at the same time, the movable body 12 is also moved in the direction A and further projects outside from the hollow portion 21 of the hollow body 22, and thus the conveyor The object 100 conveyed from 101 to 104 is pushed by the movable body 12 and placed on the other conveyors 105 to 108. After this mounting, when high-pressure air is supplied to the cylinder main body 61 from the air supply / discharge port 62, the piston rod 52 starts to further protrude out of the cylinder main body 61, and at the same time, the movable body 54 is moved in the D direction. Then, with this movement of the movable body 54, the cable inner 8 having one end 55 connected to the movable body 54 via the absorbing means 56 is pulled toward the driving means 6 against the extension elastic force of the coil spring 41. By this pulling of the cable inner 8, the movable body 12 connected to the other end 11 of the cable inner 8 is moved in the direction B, and is finally set in a state of being most inserted into the hollow portion 21 of the hollow body 22. . The above operation is repeatedly performed each time the object 100 to be selectively placed arrives.
[0024]
By the way, in the device 1, since the movement (push operation) of the movable body 12 in the direction A is performed by the extension elastic force of the coil spring 41, in other words, without pushing out the other end 55 side of the cable inner 8, Since the one end 11 of the cable inner 8 is pulled, the buckling of the cable inner 8 in the cable outer 7 does not occur, and the cable is not damaged by the buckling of the cable inner 8. Since no buckling occurs, an inexpensive stranded cable can be used for the cable inner 8. Moreover, in the device 1 of the present embodiment, since the absorbing means 56 is provided, even if the cable inner 8 extends, it can be absorbed by the extension of the coil spring 78, and the cable outer 7 due to the extension of the cable inner 8 can be absorbed. Inconveniences such as buckling of the cable inner 8 in the inside, damage to the cable outer 7 due to the buckling, and inhibition of movement of the cable inner 8 with respect to the cable outer 7 do not occur.
[0025]
In the apparatus 1, in order to prevent the cable inner 8 from being stretched, the piston rod 52 is moved so that the movable body 54 is slightly moved in the D direction even after the movable body 12 comes into contact with the lid 25 by the movement in the B direction. Relative to the movement stroke of the movable body 12 (the distance from the position slightly before the step 34 of the movable body 12 abuts the stopper member 33 to the position where one end of the movable body 12 abuts the lid 25). However, even if it is set in this way, the difference can be absorbed by the contraction of the coil spring 78 of the absorbing means 56.
[0026]
Further, since the cable inner 8 is merely locked by the stopper 81 at the other end 55, the cable inner 8 can be pulled out from the nut 74, the joint fitting 77 and the adjustment bolt 80 by removing the stopper 81. By replacing the screw 39 with the female screw hole 38, the cable inner 8 can be easily replaced.
[0027]
In addition, since the respective movable bodies 12 of the four operation heads 4 can be moved simultaneously, there is no need for a detector for synchronization or the like, and the objects 100 conveyed from the conveyors 101 to 104 are synchronized. , And can be simultaneously placed on the other conveyors 105 to 108. This synchronous operation is particularly useful when a plurality of operating heads 4 are arranged around one article and are lifted without tilting. The operating head 4 and the cable 2 are not limited to four sets, but may be one to three sets or five or more sets. Further, in the above example, the hollow body 22 is provided in the head body 10, but without such a hollow body 22, the lid 25 is configured as a head base and corresponds to the hollow portion 21 of the hollow body 22. For example, when the present apparatus is used for a lifter mechanism of a press apparatus, the apparatus may be formed in a press die.
[0028]
【The invention's effect】
As described above, according to the present invention, since the elastic means is provided between the head main body and the movable body of the operation head, there is no possibility of buckling of the cable inner, and therefore, a relatively inexpensive stranded cable as the cable inner. Can be used. Further, since the apparatus further includes an absorbing means for absorbing the extension of the cable inner, the inconvenience caused by the extension of the cable inner can be eliminated, and the moving amount of the movable body of the operating head and the cable inner of the driving means can be reduced. It is not necessary to set the relationship with the amount of pull so accurately, and assembly adjustment can be simplified. Further, since the synchronous operation can be performed, it can be optimally used for a lifter mechanism or the like for remotely lifting a molded product after pressing from a molding surface of a press die.
