DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described below with reference to the drawings. The apparatus shown in FIG. 1 comprises a crankshaft balancing device 1 having a measuring station 2 and a balancing station 3, and
A gate-shaped carrier 4 is provided. The gate-shaped transfer device 4 has a member 6 which can be horizontally moved by a guide rail 5. The member 6 carries two vertically movable grippers 7,8. The gate-shaped transfer device 4 includes a balancing device 1 and transfer conveyors arranged on both sides thereof, that is, a carry-in conveyor 9,
It is provided so as to straddle over the carry-out conveyor 10 for the completed rotating body within the allowable value and the carry-out conveyor 11 for the rotating body outside the allowable value. The balanced crankshaft is the carry-in conveyor 9,
The gripper 7 and the gripper 7 are conveyed to a conveyance position in a posture suitable for conveyance, gripped by the gripper 7, and carried into the measurement station 2. After measuring the imbalance, the measured crankshaft is carried by the gripper 8 to the balancing station 3 and at the same time by the gripper 7 the next crankshaft is brought into the measuring station 2 for measuring the imbalance. After balancing the unbalance at the balancing station 3, the balanced crankshaft is conveyed back to the measuring station 2 to measure the residual unbalance, and the other measured crankshaft is carried to the balancing station 3. Be done. If the residual unbalance of the balanced crankshaft is within the allowable value, the balanced crankshaft is carried by the carry-out conveyor 10. If the residual unbalance is still outside the allowable value after the second balancing, the crankshaft is carried out by the carry-out conveyor 11.

It is necessary to regularly inspect and adjust the measuring station 2 by means of a master member, for example after a predetermined number of crankshafts have passed. This type of machine requires various types of crankshaft balancing, and therefore requires a master member for each type. To make this process automatically feasible,
A magazine 12 as a master member is provided in a space above the carry-out conveyor 11 apart from the movement paths of the grippers 7 and 8.

As can be seen from FIG. 2, the magazine 12
Has drawers 13 and 14 arranged vertically, and a master member is housed in each drawer. Drawer 13,
14 can be quickly pulled out horizontally from the magazine, and the master member existing there is placed at the transport position E of the gripping tools 7, 8, and for example, the gripping tool 7 is carried out by the carry-out conveyor 11
When it is moved to the corresponding position above, the object is grasped by the grasping tool 7 and lifted. Depending on which master member is required for inspecting and adjusting the measuring station 2, the corresponding drawer, in FIG. 2, the drawer 13 is pulled out to the forward position, and the gripper 7 is controlled in consideration of the pulled-out position of the drawer 13. By this, the master member existing there is grasped and carried to the measuring station 2, where after the measuring station 2 is inspected and adjusted, it is stored in the drawer 13 opened again. Next, the drawer 13 is the magazine 1.
2 so that the path of the gripper is reopened to remove the out-of-tolerance crankshaft at the unloading conveyor 11.

In order to arrange the magazine 12, not in the space above the carry-out conveyor 11, but in another carry-in conveyor 9
Alternatively, the space above the carry-out conveyor 10 can be used. Further, as shown in FIG. 1, since the hoisting height of the grippers 7 and 8 is limited to the upper side, a large number of master members can be prepared, for example, above the carry-out conveyor 10. It is also possible to arrange a second magazine 15 with two drawers 16,17.

FIG. 3 shows a magazine 18 which can be applied to a balancing machine having a portal conveyor with a higher lifting height. The magazine 18 is arranged above the carry-out conveyor 19. The conveyor 19 feeds or carries the crankshaft 20 in pallets to the portal conveyor.
The magazine 18 is present at a necessary and sufficient distance from the transfer position E of the portal transfer device. The magazine 18 has six drawers 21 arranged in the vertical direction, and different master members 22 are stored in the drawers. The drawers 21 can be moved between the forward drive position and the reverse drive position by independent drive devices 23, for example, pneumatic cylinders or drive motors. Drive device 23
Are individually controllable so that selected master elements can be fed to the measuring station 2 of the balancing device.
The control of the portal carrier is associated with the control of the drive unit 23 so that one gripper of the portal carrier moves to the height of the open drawer each time a drawer 21 is opened. , Gripping or releasing the master member 22 present there. When all drawers 21 are closed, the gripper moves downwards past the magazine 18, where it grips or releases the crankshaft 20.

FIG. 4 shows an embodiment in which the master member is stored in the rotary magazine 25. The rotating magazine 25 is arranged above the transport conveyor 19. A rotating frame 26 rotatably supported on a carriage 28 about a horizontal axis.
In addition, each gondola 27 is rotatably supported about a horizontal axis. The gondola 27 is open upward, and the master member is stored in each. Gondola 2
It is preferable that the fulcrum of 7 is above the center of gravity thereof so that the posture of the master member does not change even when the rotary shaft 26 rotates. As another configuration, means for keeping the gondola 27 horizontal may be provided. The rotation of the rotary frame 26 moves the gondola having the selected master member to the take-out position existing in the upper half of the rotary frame 26.

In the case of the configuration shown in FIG. 4, the take-out position is vertically above the rotation axis of the rotary frame 26.
In order to take out the master member 22 of the rotating magazine 25,
The grips of the portal carrier always reach the same height. After that, in order for the gripper to reach the conveyor 19,
The rotary magazine 25 is moved to the position P by the horizontal movement device 29 by the carriage 28, and the rotary magazine 25 is moved to the outside of the conveying path of the gripping tool.

In the case of the magazine 30 shown in FIG. 5, the conveyor 1 is provided above the conveyor 19 and below the cover 31 with a sufficient distance from the axial planes of the grippers 7 and 8.
There is a platform 32 that can move horizontally in the longitudinal direction of 9, and the master members 22 are arranged on each pallet,
It is supported by the platform 32. The platform 32 can be manually moved to a predetermined rest position, in which case the master member 22 is in the transport position E of the gripper 7 in each rest position. The rest position is monitored by limit switches and can be automatically controlled by the operation of the machine to bring the selected type of master member into the transport position E. After moving the selected master member to the predetermined rest position, the master member is automatically transported to the measuring station and returned to this platform, as in the previous embodiments.

FIG. 6 illustrates a further aspect of the embodiment of FIG. A longitudinally expanded platform 32 carries six master members 22, here the drive motor 3
3 makes it possible to bring the selected master element to a predetermined take-out position in a completely automatic manner. This drive motor is controlled according to the operation of the machine. The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the claims.
