This stacker crane 6 has almost the same structure as the conventionally used one except for the structure of the fork.
Description of the same points as the conventional one, such as the hoisting device, will be omitted. The stacker crane 6 will be described below with reference to FIGS. 12 to 21. Fig. 12 is a schematic front view showing the stacker crane as a whole, Fig. 13 is a side view of Fig. 12, Fig. 14 is a perspective view schematically showing the stacker crane, and Fig. 15 is mounted on the stacker crane. Fig. 16 is a front view showing the lower part of the stacker crane; Fig. 17 is a front view showing the upper part of the stacker crane; Fig. 18 is a cross section showing the transmission mechanism of the fork device of the stacker crane. 19 is a front view of the fork device, FIG. 20 is an explanatory view showing the fork device in an extended state, and FIG. 21 is an explanatory view showing the fork device in a contracted state.

As shown in FIGS. 12 and 13, the stacker crane 6 includes a traveling carriage 44 that reciprocates on a mole rail 18 provided with stoppers 6S at both ends of the traveling path 5 by driving a traveling device 57, and a traveling carriage 440 and a traveling carriage 440. It has a mast 45 erected in the direction, an upper saddle 46 hanging over the upper end of the mast 45, and a hoisting bag W41 attached to the mast 45.

In order to prevent the upper saddle 46 of the stacker crane 6 from swinging, guide rollers 49 provided on the front, rear, left and right sides of the upper saddle 46 are guided by the upper rail 48 provided on the rack 4 (FIG. 14).

Furthermore, as shown in FIGS. 15 and 17, a fork device f50 is provided on the traveling cart 44 of the stacker crane 6, and is operable to extend and contract on the left and right sides of the traveling path 5, and on which a baren) P is placed. It is being

The fork device 50 is arranged on a fork base 51,
A shaft lever 52 is erected on the fork base 51 in the front-rear direction. Guide rollers 55 are rotatably attached to the upper parts of these carriages 52, and chains 54 are respectively hung on the guide rollers 55. Also,
As shown in FIGS. 14 and 15, a guide roller 56 is rotatably attached to the upper part of the carry lever 52, the cough guide roller 56 is guided on the mast 45, and the carrying lever 52 swings as it moves up and down. to prevent The chain 54 is wound up and rewound by a hoisting device 47, has one end attached to the upper saddle 46, and is guided by a guide roller 53 attached to the upper saddle 46.

Therefore, when the chain 54 is hoisted or rewound by the operation of the hoisting device 47, the barrel lever 52 moves up and down, and the fork device 50 on the fork base 51 moves up and down.

Next, the fork device 50 will be explained with particular reference to FIGS. 18 to 21. FIG. 18 is an explanatory diagram showing an outline of a fork device and a drive device for the fork device, FIG. 19 is a sectional view showing details of the fork device, FIG. 20 is an explanatory diagram showing the fork device in an extended state, and FIG. 21 FIG. 2 is an explanatory diagram showing a contracted state of the fork device. The fork device 50 is configured to be extendable and retractable in order to place the pallet P and carry it in and out. That is, the fork device 50 includes a proximal fork 58 fixed to a fork base 51, an intermediate fork 59 slidable on the proximal fork 58, a distal fork 60 slidable on the intermediate fork, and an intermediate fork 5.
It has a drive device 63 that telescopically slides the tip fork 9 and the tip fork 60. This fork device 50, in particular,
A locking pin 67A and a support pin 67B are provided at both ends of the tip fork 60. The locking pin 67A engages with a recess 31 formed in the barrel P, and the support pin 67B supports the lower surface of the pallet to maintain the horizontal state of the pallet P. Locking pin 6 of tip fork 60
7A engages with the recess 31 of the pallet P,
The pallet P can be accurately and reliably positioned on the tip fork 60 of the stacker crane 6. Therefore,
When the fork device 50 moves up and down and extends and contracts in the stacker crane 6, the baren) P moves the tip of the fork 60.
The tip fork 60 can be moved to a predetermined position together with the distal fork 60 while maintaining an accurately and reliably positioned state without moving on top.

Furthermore, a forward chain receiving member 62F and a backward chain receiving member 62R are fixed to the base end fork 58, respectively. One end of the forward chain 64F is connected to the forward chain receiving member 62F, and one end of the forward chain 64F is connected to the backward chain receiving member 6.
One end of the rearward side chain 64R is fixed to each of the chains 2R and 2R. The forward chain 64F is hooked on the forward sprocket 65F provided at the tip of the intermediate fork 59, and the other end of the forward chain 64F is attached to the proximal end 66 of the tip fork 60.
It is fixed at F. In addition, the retreating side chain 64R has a retreating side sprocket 65 provided at the tip of the intermediate fork 59.
R, and the other end of the retreat side chain 64R is fixed to the tip side end 66R of the tip fork 60. Also,
The drive device 63 rotationally drives a pinion 70 rotatably attached to the fork base 51 through a transmission device 71. Moreover, the rough black 1 is fixed to the lower surface of the intermediate fork 59 in a state extending in the longitudinal direction. This rack 6
1 is engaged with a pinion 70 attached to the fork base 51. Furthermore, guide grooves 72 and 73 are formed on both side surfaces of the intermediate fork 59. A guide roller 68 is rotatably attached to the distal fork 60, and a guide roller 69 is rotatably attached to the proximal fork 58. Since the guide roller 68 loosely fits into the guide 172 and guides the guide roller 68 through the guide groove 72, the tip fork 60 smoothly extends and contracts with respect to the intermediate fork 59. Further, since the guide roller 69 is loosely fitted into the guide groove 73 and is guided by the guide groove 73, the intermediate fork 59 can smoothly extend and contract with respect to the base end fork 58.

As described above, the fork device 50 is configured and operates as follows. First, as shown in FIG. 20, when extending the tip fork 60 of the fork device 50, the drive device 63 is rotationally driven in one direction, and the pinion 70 is rotated in the forward direction through the transmission device 71. . The rotational movement of the pinion 70 causes the rough cross 1 to move forward in the longitudinal direction. When the rack 61 moves forward in the longitudinal direction, the intermediate fork 59 moves to the forward side, that is, to the side where it extends with respect to the proximal fork 58. When the intermediate fork 59 extends, the sprocket 65F attached to the intermediate fork 59 is rotated by the chain 64F, thereby increasing the distance between the forward chain receiving member 62F and the sprocket.
The distance between 5F and the proximal end 66F becomes shorter. Therefore,
The tip fork 60 moves toward the forward side, that is, the side where it extends, relative to the intermediate fork 59. Therefore, the fork device 50 will extend the tip fork 60.

Further, as shown in FIG. 21, when retracting the tip fork 60 of the fork device 50, the drive device 63 is rotated in the opposite direction to the above, and the pinion 70 is rotated in the backward direction through the transmission device 71. Exercise. Binion 7
The rotational movement of 0 moves the rack 6I to the retreating side in the longitudinal direction. When the rack 61 moves to the backward side in the longitudinal direction, the intermediate fork 59 moves to the backward side, that is, the proximal fork 5
Move to the side that pulls in against 8. The retraction of the intermediate fork 59 is performed by the sprocket 6 attached to the intermediate fork 59.
5R is rotated by the chain 64R, thereby increasing the distance between the retreating side chain receiving member 62R and the sprocket 65R.
The distance to 6R becomes shorter. Therefore, the tip fork 60 moves toward the retreating side, that is, the retracting side, relative to the intermediate fork 59.

Therefore, the fork assembly 250 causes the tip fork 60 to retract.

Therefore, if the stacker crane 6 is provided with a fork device [50 that extends and contracts with respect to one side of the traveling path 5 and a fork device 50 that extends and contracts with respect to the other side, the stacker crane 6 can move along the traveling path 5. A fork device 50 is provided that can extend and retract on both sides.

Alternatively, for the stacker crane 6, instead of providing the two telescoping fork devices f50, a fork device that rotates on the fork base 51 (not shown) may be provided, so that one fork device 250 can be used not only in both directions. , it is also possible to orient the fork device in a desired direction.

Therefore, the stacker crane 6 moves the fork device 5o up and down by the hoisting device 47, and also moves the fork device 5o up and down the traveling path 5.
By having a fork device 50 that can extend and contract in the left-right direction, the tip fork 6o of the fork device 50 can be extended to below the baren (P) located at a predetermined location.
Next, when the tip fork 60 is slightly raised, the locking pin 67A of the tip fork 6o engages with the recess 31 of the pallet P, and the lower surface of the ballet P is placed on the support pin 67B. By contracting the tip fork 60 in this state, the pallet P can be positioned on the fork base 51. Next, the traveling device 57 drives the traveling cart 44 of the stacker crane 6, and the controller commands the traveling device 57 to move it to a predetermined position, for example, the setup indexing device 9, each intermediate transfer device 7 of the various processing machines 1.23, and the rust prevention treatment device. 0,
The fluid spray is moved to the equipment 212 or to the shelf 19 of the rack 4. The fork device 250 is operated again to extend the tip fork 6o and move the pallet P to the position R. When the tip fork 6o is extended to the position where the barre (P) is placed, if the tip fork 60 is moved slightly downward, the locking pin 67A of the tip fork 6o that was engaged with the recess 31 of the bar (P) will be removed. leaves. In this state, the tip fork 60 is retracted, the fork device 5o is contracted to the state shown in FIG. 21, and the stacker crane 6 is moved to the next target location.

Therefore, this stacker crane 6 carries the pallet P received by the setup indexing device 9 to the rust prevention treatment device 10, the fluid spraying device 12, the rack 4, or the intermediate delivery device 7 of various processing machines 1.2.3. can perform the functions of Alternatively, the stacker crane 6 can be used for various processing machines 1,
2. Receive the pallet P from the intermediate transfer device 7 that received the pallet P carried out from 3, and carry it into the intermediate transfer device 7 of another processing machine, or carry it out to the step 4 or the setup indexing device 9. can perform the functions of (Hereinafter, this page margin) Next, regarding the wire electric discharge machining Ill among the processing machines in this FMS,

Regarding wire electric discharge machining Ill, when wire electric discharge machining is performed on a workpiece W, machining waste or products machined into a machined shape are generated that are separated from the workpiece W. Unless these workpieces are automatically removed during electrical discharge machining in wire electrical discharge machining Ill, subsequent electrical discharge machining cannot be performed. Here, an example of a work piece removing device will be described with reference to FIGS. 44 and 45. FIG. 44 is a schematic front view showing an example of a workpiece removing device attached to a wire electric discharge machine, and FIG.
The figure is a side view of FIG. 44.

This work piece removing device 130 is attached to the head IH of the wire electric discharge machine 1 with an upper mounting member 131 and a lower mounting member 13.
It is fixed by 2. The upper mounting member 131 includes
A dog 133 is attached that passes through and guides a pole rod 135 that moves up and down. This pole thread rod 135 has a ball spline groove 141 and threads 142 formed therein. The lower mounting member 132 is provided with a sliding member 62 that engages with the ball spline groove 141, is fixed in the rotational direction, and slides in the vertical direction. A gear 145 is fixed to this sliding member 62. This gear 145 includes a gear 146 that meshes with the gear 145 and rotates around the outer circumference of the gear 145 over 270 degrees.
are engaged.

This gear 146 is fixed to a rotating shaft 148 rotatably supported by a support member 147 attached to the lower mounting member 132. Rotation of the rotating shaft 148 is performed by the operation of the servo motor 137, which is a second servo motor. Therefore, when the rotating shaft 148 is rotated by the servo motor 137, the gear 146 meshes with the gear 145, and the gear 145
The pole neck rod 135 is rotated by rotating the gear 145 or rotating the gear 145 by rotating the gear 146 .

Furthermore, a pole stud 143 that engages with the screw 142 is attached to the lower mounting member 132.

A nut 149 is fixed to the nut rotation support holder 53 attached to the lower mounting member 132 and fixed to the sliding member 62, and a worm wheel 144 is fixed to the nut 149 by meshing with the screw 141. The worm wheel 144 is rotated by the operation of a servo motor 136, which is a first servo motor attached to the lower mounting member 132. Therefore, when the worm wheel 144 is rotated by the operation of the servo motor 136, the sliding member 62 moves the pole rod 135 up and down. Furthermore, the servo motor 137 and the servo motor 136 operate, and the gear 1
45 and the worm wheel 144 rotate in synchronization, their rotational movements cancel each other out, resulting in a stopped state, and only the ball loft 135 rotates.

Furthermore, an electromagnetic holder case 138 is attached to the lower end of the ball-sleeping rod 135. A ball screw 150 is attached to this electromagnetic holder case 138, and a ball screw rod 139, which is a second ball screw rod, includes a screw 151 that meshes with the ball screw 150, and extends through the electromagnetic holder case 138. A ball spline 152 is formed on this ball screw rod 139. Furthermore, a servo motor 153, which is a third servo motor, is provided in the 11-magnetic holder case 138' to rotate a worm wheel attached to the ball screw 150. Therefore, when the servo motor 153 operates and the worm wheel of the ball screw 159 rotates, the ball screw loft 139 reciprocates in the horizontal direction with respect to the IT magnetic holder case 138. An electromagnetic holder 140 is attached to the tip of the ball rod 139, and a magnet such as an electromagnet is attached to the magnetic holder 140.

Since this work piece removing device 130 is configured as described above, the ball screw rod 139 attached to the lower end of the ball screw rod 135 that moves vertically and rotates is integrated with the ball screw rod 135. In addition to being able to perform vertical and rotational movements, the ball mesh rod 139 itself can also move horizontally relative to the ball mesh rod 135, so the electromagnetic holder 140 attached to the tip of the ball mesh rod 139 can be moved in three dimensions. You will be able to move through space.

Therefore, this work piece removal equipment W130! Magnetic holder 14
If the electromagnet attached to the wire electric discharge machine 1 is configured to protrude from the workpiece removal device 130, it will come into contact with the upper surface of the workpiece W positioned on the pallet P of the wire electric discharge machine 1. You will be able to do this. Therefore, just before the workpiece is separated from the workpiece W by a command from the controller, if the workpiece removal device j130 is activated to bring the electromagnet into contact with the workpiece and attract the workpiece, the workpiece will be removed. The workpiece adsorbed to the amstone 140 can then be moved upward and stored in a predetermined workpiece storage location without falling, and the workpiece separated from the workpiece W will not damage the machined surface. , the work piece can be eliminated.
