Description

Description: TECHNICAL FIELD The present invention relates to a tire loading / unloading / loading device, and more specifically, it relates to a tire loading / unloading device and a tire loading device. The present invention relates to a tire loading / unloading and loading device that automatically loads a tire block to a loading side and automatically loads the tire block onto a rack in a state where the tire block is tilted.

[Prior art]

Conventionally, the work of transporting tires of various sizes to a rack loading position and loading each of the tires on the rack has been performed manually.

That is, first, an operator sorts tires of various sizes that have been molded and transported by size, and stacks the sorted tires in a predetermined number to stack them, and then the stocked tire blocks are transported by a conveyor and a transporter. It was conveyed to a tire loading position via a conveyor or the like, and a predetermined number of tire blocks were loaded onto a rack while the tire blocks were laid down there.

However, in the conventional work as described above, since a series of work such as tire sorting, tire stacking, and rack loading are all performed manually, work efficiency is extremely poor and a rack of a certain width is used. On the other hand, the work of loading the maximum number of tires was extremely difficult and dangerous.

Therefore, the tire tilting device 400 includes the guide roller 3
When the tire block Wa conveyed by 40 is received, the operating rod 451 of the cylinder 450 is contracted to keep the tire holding member 430 in a vertical state, and when the tire block Wa is supplied to the inside of the tire holding member 430. When the claws 415a, 415b to be clamped are contracted through the cylinder 435 to clamp the tire block Wa and the actuation rod 451 of the cylinder 450 is extended, the tire holding member 430 holding the tire block Wa is hinged. 440
Tire block that was upright by turning 90 ° around the fulcrum
Defeat Wa to a horizontal position.

Then, the tire block Wa which has been laid down as described above is turned through the two cylinders 410 in the direction of the arrow with the pin 460 as a fulcrum as shown in FIG. 9, and the tire block Wa is clamped. The claws 415a and 415b that have been released are transferred to the tire loading device 500 side by releasing the cylinder 435.

Next, the above-mentioned tire loading device 500 is, as shown in FIGS. 10 to 13, a tire loading section 501 of the tire rack device 501.
A tire transfer device is installed between the two columns 503 installed on the side of a.
502 is provided.

One end of a first arm 505 which swings about a shaft 504 is pivotally supported by the two columns 503, and the other end of the first arm 505 is connected to a second arm 507 via a shaft 506. Is rotatably supported at one end.

The other end of each arm 507 is connected to both ends of a tire support bar 509 in which a rotatable collar 508 is fitted, and a support arm 510 connecting the shaft 506 and a column 503 is also connected to the tire support. Tire support bar 512 parallel to bar 509
Both ends of are supported.

A first fluid cylinder 513 (air cylinder) is provided between the shaft 504 connecting the first arm 505 and the second arm 507 and the support 503, and both ends of the tire support bar 509 are connected to each other. A second fluid cylinder 514 (air cylinder) is provided between the support column 503. A base end of a cylinder 516 (air cylinder) is supported by the support arm 510 via a bracket 515, and a rod 516 of the cylinder 516 is supported.
As shown in FIG. 13, guide plates 519 for holding both sides of the tire W are disposed opposite to each other at the tip of a via brackets 517 and hinge plates 518, respectively.

The guide plate 519 is supported so as to operate while inclining inward so as to hold a plurality of tires W from both sides.

A tire support bar 520 is provided between the support frames 521 of the tire rack device 501, and is used to transfer the tire W rotated by the tire support bar 509 of the transfer device 502. It supports the bottom.

Next, a tire transfer operation by the transfer device 502 having the above-described configuration will be described.

First, the tire support bars 509 and 512 of the tire transfer device 502.
When the tires W sequentially conveyed by a not-shown conveyer conveyor or the like are placed in a packing form in which the number of tires W that can be accommodated in the tire rack device 501 is placed, a plurality of tires W
The weight of the tire W is supported by the tire support bars 509 and 512, and both sides of the tire W are held by the guide plates 519 in a state where the tire W is prevented from falling. From this state,
The cylinder 516 operates to sandwich both sides of the plurality of tires W by the guide plates 519 and hold them.

From such a state, first the first fluid cylinder 513 is moved to the first
The contraction operation is started from the state shown in FIG. 3, and the tire support bars 509 and 512 on which the tire W is mounted and the guide plate 519 are set as shafts.
The tire W is moved clockwise to a position Wx by using 504 as a fulcrum. At this time, tire support bar 509,512
Since a part of the tire Wx supported by the guide plate 519 and the guide plate 519 are already located in the support frame 521 of the tire rack device 501, a plurality of tires Wx are transferred while being supported by the tire support bar 520 by their own weight. Cylinder 516, which is possible and therefore clamped on both sides by said guide plate 519.
Release the holding power of. By releasing this cylinder 516,
In the next step, the swing (rotation) around the shaft 506a which is the second swing center and the resistance applied to the tire Wx when the tire is pushed can be reduced.

Next, when the second fluid cylinder 514 is contracted from the position of the tire Wx that is supported by the tire support bar 520 of the tire rack device 501 and has not yet been inserted into the rack,
The tire support bar 509 on which the tire Wx is mounted is further rotated clockwise to rotate the tire loading section 5 of the tire rack device 501.
The tire Wy is loaded into the tire rack device 501 from 01a.

That is, when the tire Wx passes a certain point while rotating, the tire Wx rolls into the rack due to its own weight, and the transfer work of the tire Wa is completed.

Further, although not shown, by adding an elevating device to the transfer device 502, it is possible to transfer a plurality of tires W collectively on a multi-tiered shelf.

The present invention is configured as described above, and when molded tires W of various sizes are conveyed, tire sorting from tire sorting, tire loading and unloading, tire stock, tire transportation, and tire block Wa are performed. Since the series of operations from loading the tires to the tire loading device 500 and loading to the rack R are all automatically performed by the command from the drive control device 600, the work efficiency is extremely good and safe and reliable. It is possible to carry it out.
