<The role of the guiding device>

According to the automatic lathe system 100 configured as described above, the conveyor 20 moves the body 21 along the rail 22 to reach the position (1) of Fig. 1A. Thereafter, the arm 21b is rotated to the horizontal state (position (5) of Fig. 1B).

The conveyor 20 extends the arm 21b toward the module 14 in a state in which the claw 21c is opened. When the claw 21c reaches the position of the workpiece 1 held by the module 14, the claw 21c is closed to hold the workpiece 1. The module 14 is, for example, a jig that opens the spindle and retracts the spindle to release the workpiece 1, whereby the workpiece 1 is delivered to the conveyor 20.

The conveyer 20, after receiving the workpiece 1, shortens the arm 21b, and then rotates the arm 21b to the vertical state (position (4) of Fig. 1B). The conveyor 20 moves the body 21 along the track 22 to pass the position (2) of Fig. 1A to the position (3).

Thereafter, the arm 21b is rotated to the horizontal state (position (5) of Fig. 1B). The conveyor 20 extends the arm 21b toward the workpiece setting portion 31 of the guiding device 30. When the claw 21c reaches the installation table 31a (see FIG. 3) located at the rising position, the claw 21c is opened, and the workpiece 1 is placed on the installation table 31a.

The transporter 20 thereafter shortens the arm 21b and rotates the arm 21b to the vertical state (position (4) of Fig. 1B) and then stops.

The setting table 31a is lowered after the workpiece 1 is placed. During the lowering of the installation table 31a, the support of the workpiece 1 placed on the installation table 31a is moved to the bottom plate 31b above the installation table 31a.

Since the bottom plate 31b is inclined, the supported workpiece 1 is slid (including rolling) from the bottom plate 31b in the oblique direction thereof, and then fixed by the fixed ejector 32 and fixed to the bottom plate 31b. The guide surface 32a of the ejector 32 slides down.

Here, the control device of the automatic lathe system 100 controls the air pressure in response to the workpiece 1 provided in the installation table 31a being the workpiece 1A processed in the processing path A or the workpiece 1B processed in the processing path B. Cylinder 34.

Specifically, when the workpiece 1 is the workpiece 1A, the control device causes the pneumatic cylinder 34 to be in a contracted state, so that the rotary ejector 33 becomes as shown in FIG. 2. As shown in Fig. 3, the swinging state of the hole 32c is blocked by the first plate-like member 33a.

According to the closed state of the hole 32c of the first plate-shaped member 33a, the workpiece 1A that has landed on the guide surface 32a passes through the upper surface of the first plate-like member 33a which is a part of the guide surface 32a, and is formed along the guide. The movement from the lower end of the face 32a slides down the road. After the lower end of the guide surface 32a, the recovery box 41 for the workpiece 1A is disposed, whereby the workpiece 1A can be housed in the recovery box 41.

On the other hand, when the workpiece 1 is the workpiece 1B, the control device causes the pneumatic cylinder 34 to be extended, and the rotary ejector 33 is inserted into the hole by the second plate-like member 33b as shown in Figs. 4 and 5A. The swing state of 32c. Thereby, the first plate-shaped member 33a is retracted from the hole 32c, and is erected upward from the guide surface 32a.

According to the closed state of the hole 32c of the second plate-shaped member 33b, the workpiece 1B that has slid down on the guide surface 32a hits the back surface of the joint member 33c that is integrally erected with the first plate-shaped member 33a, so that it becomes a guide surface. The movement of the upper surface of the second plate member 33b at one of the portions 32a is restricted, and is held on the second plate member 33b. The joining member 33c is a workpiece receiving portion that receives the workpiece 1 on the second plate-shaped member 33b and holds the workpiece 1 in a state of restricting the movement of the workpiece 1. As shown in FIGS. 3 and 5A, the surface of the joint member 33c is provided with a punching and absorbing member 33g for absorbing the rubber or the like which is washed at the time of receiving the workpiece 1, and the workpiece 1 is stopped by the punching and absorbing member 33g.

Next, the control device causes the pneumatic cylinder 34 to be in a reduced state, As shown in FIG. 5B, the rotary ejector 33 is swung to return to the state in which the hole 32c is closed by the first plate-like member 33a, and the second plate-shaped member 33b is retracted from the hole 32c, and is held in the state of being retracted from the hole 32c. The workpiece 1 on the second plate-shaped member 33b passes through the hole 32c and moves to the lower side of the guide surface 32a.

In this state, the distal end side (the right end side in FIG. 5B) of the second plate-shaped member 33b is inclined downward. Therefore, the workpiece 1B supported by the second plate-shaped member 33b slides along the movement path formed to the lower end of the second plate-shaped member 33b, that is, the lower end. After the lower end of the second plate-shaped member 33b, the recovery box 42 for the workpiece 1B is disposed, whereby the workpiece 1B can be recovered in the recovery box 42.

Thereafter, the second plate member 33b slides and is guided to the collection box 42, so The damage of the outer surface of the workpiece 1B can be prevented or suppressed as compared with the case where the hole 32c is freely dropped, and the posture change of the workpiece 1B in the free fall can be prevented or suppressed. That is, according to the guiding device 30 of the present embodiment, the workpiece 1 can be stably and smoothly guided to the corresponding recovery box 41 or the recovery box 42.

In the state in which the workpiece 1B is received by the first plate-shaped member 33a (the second plate-shaped member 33b is in a state in which the hole 32c is plugged), the guide device 30 of the present embodiment is returned to the first plate-like member 33a. In the state of the hole 32c, the shortening length of the piston rod 34b may be changed stepwise.

In this case, the inclination angle of the second plate-shaped member 33b is changed in accordance with the shortened length of the piston rod 34b, so that a plurality of moving passages having different inclination angles can be formed. Thereby, the guiding device 30 arranges a plurality of collection bins corresponding to the respective moving passages, whereby the workpiece 1B can be selectively collected into the corresponding collection bins as a plurality of types.

The guide device 30 of the present embodiment is formed by bending the introduction portion 33f of the front end of the first plate-shaped member 33a. Therefore, as shown in FIG. 3, the first plate-shaped member 33a is inserted into the hole 32c. The portion 33f is lower than the guide surface 32a adjacent to the introduction portion 33f. As a result, the workpiece 1A that has slipped on the guide surface 32a can be smoothly placed on the upper surface of the first plate-like member 33a.

Further, the second plate-shaped member 33b may have an introduction portion that is curved in a direction away from the first plate-shaped member 33a at its tip end.

In the guide device 30 of the present embodiment, the barrier wall 33h is formed on both side portions of the second plate-shaped member 33b, and as shown in FIG. 5B, It is possible to prevent the workpiece 1B that has slipped off by the second plate member 33b from falling to the side.

Further, the first plate-shaped member 33a may have a barrier wall formed on both side portions thereof.

Since the guide device 30 of the present embodiment also has the barrier wall 32b formed on both side portions of the guide surface 32a, it is possible to prevent the workpieces 1A, 1B that slide down on the guide surface 32a from falling to the side.

The barrier wall 33h of the second plate-like member 33b is received in the slit 32d of the barrier wall 32b, thereby preventing interference between the barrier wall 33h and the fixed ejector 32.

In the guiding device 30 of the present embodiment, the joining member 33c functioning as the workpiece receiving portion is provided with the punching and absorbing member 33g, so that the flushing of the workpiece 1B can be reduced.

Further, the workpiece guiding device of the present invention may not be provided with a punching and absorbing member.

In the guide device 30 of the present embodiment, the first plate-shaped member 33a and the joint member 33c are integrated, and the first plate-shaped member 33a is configured to restrict the movement of the workpiece 1 on the second plate-shaped member 33b. However, the first plate member 33a itself can be used as the workpiece receiving portion to receive the workpiece 1, and the workpiece 1 can be held on the second plate member 33b. Further, a workpiece receiving portion different from the first plate-shaped member 33a may be integrally provided on the second plate-shaped member 33b side.

In the guiding device 30 of the present embodiment, the guiding surface 32a is inclined in a direction substantially orthogonal to the axis N of the workpiece 1 having a circular cross-sectional profile, so that the inclination of the workpiece 1 along the guiding surface 32a can be made.
