The present invention relates to a feeding device for a stack of tubes for feeding a mounted wood onto a lower tube.

[0002]

2. Description of the Related Art When a pipe is manufactured at a foundry and then shipped, a plurality of pipes in a horizontal direction are generally stacked in a plurality of stages. In such a stacking, a plurality of wooden cycle trees are put on the lower pipes, and then the upper pipes are stacked on these cycle trees to stably support the upper pipes. doing. Conventionally, the supply of a tree onto the lower pipe is performed manually by an operator.

[0003]

However, such a manual operation is extremely inefficient in a production line in which tubes must be manufactured and shipped one after another, and the stacking of tubes having a considerable weight. Since the work is performed on site, there is a problem that it involves danger.

Accordingly, an object of the present invention is to solve the above-mentioned problems and to efficiently and safely supply a cycle in a production line in which pipes must be manufactured and shipped one after another. I do.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a means for transporting a plurality of trees along a transport path formed in the vicinity of a pile of pipes. Between the first predetermined position and the first wheel supply position in the pipe, receiving the wheel from the transporting means and supplying the received wheel to the first wheel supply in the pipe. A first wheelchair transfer device for transferring to a position, a second wheelchair supply position in a pipe and a second predetermined position corresponding to the transfer path, and a wheelchair. And a second cycle transfer device for transferring the received cycle to a second cycle supply position in the pipe, and means for supplying the cycle to the transport means. .

[0006]

In such a configuration, a plurality of trees are supplied from the wheel supply means to the transport means in the vicinity of the pipe stacking station, and the plurality of supplied wheels are transported along the transport path. As a result, it is temporarily stored in the transport means. The cycle in the transport means is received by a first cycle transfer device located at a first predetermined position, and is transferred by the transfer device to a first cycle supply position in the lower tube to be transferred to the upper portion of the tube. It is put on. Another cycle in the transport means is received by a second cycle transfer device located at a second predetermined position, and is transferred to the second cycle supply position in the lower pipe by this transfer apparatus. Can be put on top.
When the first and second cycle transfer devices remove the cycle from the transport means, the cycle is supplied from the cycle supply means additionally.

Is supplied.

The conveyor 27 holds a large number of wheels 24 supplied from the cassette member 39 in a state in which the wheels 24 are pitch-fed along an endless transport path in a state where the wheels 24 are sandwiched between the support brackets 34. Transport.

The supply of the cycle 24 to the pipes 12 supported on the table 23 of the lifter truck 22 is performed as follows. First, in the wheel transfer device 60, as shown in FIGS. 9 and 10, both the wheel receiving rods 70 are simultaneously rotated by the cylinder device 75, and the stoppers 71 are switched to the horizontal orientation. In this state, the moving frame 68 is moved by the cylinder device 69.

Without interfering with the wheel 24, it is inserted between the adjacent wheels 24 vertically and is inserted farther than the wheel 24.

In this state, when the wheel receiving rod 70 is rotated by the cylinder device 75, the stopper 71 assumes an upward posture. When the moving frame 68 is moved in a direction away from the conveyor 27, the stopper 71 engages with the arbor 24, and the arbor 24 supported by the supporting bracket 34 is moved from the supporting bracket 34 to the arbor receiving rod 70. To be taken out of the conveyor 27.

At this time, as shown in FIG. 7, the second bogie 59 of the lower second wheel transfer device 58 correspondingly approaches the conveyor 27 of the wheel feeder 26, as shown in FIG. When the telescopic frame 63 of the cart 59 extends downward, the cycle 24 supported by the cycle receiving rod 70 of the cycle delivery device 60 can be clamped by the clamp claws 65.

When the cycle 24 is clamped, the telescopic frame 63
The wheel 24 is lifted upward from the receiving rod 70 by the shortening operation described above, and is brought above the pipe 12 by the travel of the second carriage 59. Then, it is lowered to the upper surface of the plurality of tubes 12 by the downward extension operation of the telescopic frame 63, and the clamp claws 65
By the opening operation, the plurality of tubes 12 are placed over the upper surfaces of the plurality of tubes 12 in a direction orthogonal to the tubes 12.

At the same time, the upper first wheel transfer device 47
In the first carriage 48, the swinging frame 51 as shown in FIG.
By the swing of the telescopic frame 54 is placed in a horizontal position, and the carriage 48 travels in a direction approaching the wheel supply device 26, whereby the clamp claws 56 are attached to the wheel 24 supported by the support fittings 34 of the conveyor 27. Located facing each other. When the telescopic frame 54 extends in this state, the clamp claw 56 enters the conveyor 27 and clamps the cycle 24.

Next, when the telescopic frame 54 is shortened in a direction away from the conveyor 27, the cycle 24 clamped by the clamp claws 56 is taken out from the conveyor 27 in the horizontal direction.
Traveling of the carriage 48 results in the upper part of the pipe 12 at a position remote from the wheel feeder 26. When the swing frame 51 swings in this state, the telescopic frame 54 faces downward, and thereafter, as in the case of the second bogie 59, the wheel block 24 is perpendicular to the upper surface of the tube 12. It is placed in the direction of As described above, since the first and second wheel transfer devices 47 and 58 transfer the wheel 24 at the same time, this transfer operation is performed efficiently.

As a result, as shown in FIG. 1, a pair of wheels 24 are supplied to the plurality of tubes 12 on the table 23 of the lifter truck 22 in the stacking place 19 at positions spaced apart in the axial direction. Is placed. Therefore, by lowering the table 23 by one stage, the next tube 12 is successively stacked.

When the pipes 12 are stacked by a predetermined number of levels,
The lifter truck 22 moves toward the unloading site 20, and the stacked tubes 12 are unloaded from the unloading site 20 by a forklift truck or the like.
