Since this embodiment is constructed as described above,
Discharging the goods to be conveyed from within 30 is performed as follows.

First, the pallet 1 is positioned at the lowest limit near the lower sprockets 3, 3 as shown by the solid line in FIG. And
The carrier 30 containing the cast or steel chips is moved into the pallet 1 from the carrier entrance 1a of the pallet 1 while traveling on the floor by the car 31. At this time, the engaging projection 30a of the carrier 30 engages while sliding while being sandwiched between the engaging projections 1g, 1g of the pallet 1.

Next, the opening / closing control device of the trough opening device 22 is operated based on whether the chips are cast or steel. That is, when the chips are castings, the air cylinder 24 is contracted to open the door 27. When the cutting powder is steel, the air cylinder 24 is extended to close the door 27.

When the drive control device operates the drive mechanism 8, the drive force of the motor 12 is transmitted to the sprocket 14 via the speed reducer 13. The driving force of the sprocket 14 is further transmitted through the chain 15 and the sprocket 9 to the shaft 10 and the sprocket.
It is transmitted to 7, 7 and the sprockets 7, 7 drive the chains 2, 2.

When the chains 2 and 2 are driven, the pallet 1 and the transport vehicle 30 are lifted by being lifted by the brackets 1f and 1f. At this time, the rollers 1d, 1d, 1e, 1e of the pallet 1 are the guides 1
Rollers 1d, 1d, 1e, 1e are guided so as to sandwich 6,16,
The pallet 1 and the carrier 30 are raised while being guided.
When the pallet 1 and the carrier 30 are guided to the arcuate portions above the guides 16 and 16, the loci of the rollers 1e and 1e are changed.
Although it is no longer concentric with respect to the locus of, the contact between the rollers 1e, 1e and the guides 16, 16 at the missing portions 16a, 16a of the guides 16, 16 is removed, and the rollers 1d, 1d are located outside the guides 6, 16. Since it abuts on the guide portions 16b, 16b, the pallet 1 and the carrier 30 are guided without any trouble.

In this way, when the pallet 1 and the transport vehicle 30 are guided to the end portions of the upper portions of the guides 16 and 16, the dog 35 of the pallet 1 operates the limit switch 37 to stop the auxiliary drive mechanism 8 and the chains 2 and 2. As a result, the pallet 1 and the carrier 30 stop. At this time, as shown by the chain line in FIG. 1, since the pallet 1 is in a turning state, the transport vehicle 30 is also turning at the same time. Then, all the chips in the transport vehicle 30 are dropped and discharged, and are thrown into the feeding port of the screw conveyor 18. When the motor 19 of the screw conveyor 18 is operated here, the screw 2 is passed through the speed reducer 19a.
1 is driven, and the chips are conveyed in the screw conveyor 18.

By the way, when the cutting powder is a casting, the cutting powder is a fine cutting powder.
The upper surface of a is conveyed by the screw 21. In addition, when the cutting chips are steel, there are long chips in addition to fine chips, and the long chips are entangled with each other to form a large lump. Therefore, in the screw conveyor 18, fine chips of steel are conveyed by the screw 21 on the upper surface of the bottom surface 20a of the trough, but long chips of steel are placed on the screw 21 in a lump intertwined with each other. It is transported in the state.

Therefore, when the trough opening device 22 is operated to open the door 27 and the chips of the casting are conveyed by the screw conveyor 18,
All the chips of the casting are dropped from the lower opening 28 and discharged, and are stored in the bucket 33 for casting chips. When the trough opening device 22 is operated in the reverse direction to close the door 27 and the steel chips are conveyed by the screw conveyor 18, all the steel chips are transferred to the trough.
It falls from the end opening 20b of 20 and is discharged without trouble, and is stored in the steel chip bucket 34.

Thus, the chips of the casting or steel are stored in the bucket 33 for casting chips or the bucket 34 for steel chips, respectively.

In this way, the carrier 30 is guided by the guides 16 and 16 while being locked to the pallet 1 and automatically and surely turns, and the chips are completely discharged without remaining inside the carrier 30. Then, the chips discharged from the transport vehicle 30 and put into the screw conveyor 18 are obtained by operating the trough opening device 22 in advance according to whether the chips are cast or steel,
The load is automatically stored in the casting chips bucket 33 or the steel chips bucket 34.

When the chips are completely discharged from the transport vehicle 30, the drive controller 8 reverses the driving mechanism 8 to lower the pallet 1 and the empty transport vehicle 30 while guiding the guides 16, 16.

When the pallet 1 and the carrier 30 descend to the lower limit position,
The limit switch 36 is actuated by the dog 35 of the pallet 1, the drive mechanism 8 is stopped, and the pallet 1 and the transport vehicle 30 are stopped. Then, after the carrier 30 is pulled out, the work is repeated from the beginning in the same procedure.

[Effect of device]

As described in detail above, according to the carrier rotating type carrier device of the present invention, the following effects and advantages can be obtained.

(1) The transport vehicle can automatically and surely turn only by ascending / descending upward along the guide mechanism to completely discharge the transported object from within the transport vehicle.

(2) Since only the weight of the pallet and the weight of the carrier are received by the endless chain, the load is reduced, and even when turning, the upper sprocket side end is formed in an arc shape along the upper sprocket and the lower sprocket side end is Is extended in a substantially vertical direction, and the guide mechanism with which the engaging means provided on the pallet slidably engages causes the pallet to directly turn along the moving direction of the endless chain, so that there is little variation in load.

(3) There is an advantage that the carrying means that has received the carried product can further carry the carried product to a desired position.
