[0006]

According to the present invention, there is provided a transporting device in which a plurality of pallets are movably installed in a vertical and horizontal direction on a floor surface, and a bar is attached in the longitudinal direction of the central area of the back surface of the pallet. Center bar, which is a bar divided into three, is 9 from the center axis.
It is provided so as to be rotatable only in one direction within a range of 0 °, and wheels are arranged at four corners of the pallet so that the wheels can be turned in a vertical or horizontal direction. The center bar and the wheels are interlocked with each other. A rotation base having a pallet feed mechanism for holding the center bar is provided on the floor surface concentrically with the center axis of the center bar, and is rotatable in the range of 90 ° in the vertical and horizontal directions. Is a conveying device for a multi-level parking pallet that transmits the rotation of the pallet to the center bar to change the transfer direction of the pallet.

The present invention will be described below with reference to the drawings.

FIG. 1 is an overall plan view of the present invention. The pallets 1, 1 are transferred on the guides 3, 3 by the pallet feed mechanism 10 on the floor surface to the traverse a or the travel b indicated by the arrow. 2 shows an elevator as an example, and the guide 3 and the pallet feeding mechanism 10 are provided in the elevator.

The pallet 1 of the present invention has a bar 4 attached thereto as shown in FIG. The bar 4 is provided in the longitudinal direction of the central area of the pallet 1 and is divided into three parts 4a and 4b. Three
The center bar 4-2, which is divided into equal parts, is 90 ° by the central axis 5.
In the range of, it is rotatable only in one direction.

Wheels 6 are provided at four corners of the pallet 1, and the wheels 6 are
Has a pedestal 7, and can be converted into traverse or traveling by the rotation of the central pedestal 9 via the bar 8.

The wheels 6 are formed in a chain shape, and the edges of the wheels 6 bear the load of the pallet and the vehicle. The pallet feed mechanism 10 of the present invention is shown in FIG.

In the drawing, a large diameter roll 11 and a small diameter roll 1
2 is arranged so as to hold the center bar 4-2.
The large-diameter roll 11 is connected via a sprocket 16 to a gear 17 of a speed reducer 13, which is connected to a drive motor (not shown). 14 is a roll shaft of the large-diameter roll 11, 15 is a sprocket gear, and the large-diameter roll 11 is fixed by holding bases 18 and 19 via bearings.

Further, the small diameter roll 12 is held by a roll shaft 20 and provided with a pressing mechanism 30. As shown in FIG. 4, the pressing mechanism 30 includes a roll shaft 20, a gripper 22 and a pin 25.
The pressure force of the spring 23 is transmitted to the small-diameter roll 12 by the presser 21. 24 is a fixed base.

According to experiments, when the large-diameter roll 11 is covered with an elastic body and the small-diameter roll 12 is made of metal, the friction driving effect is great.

The pallet feed mechanism 10 of the present invention is provided on the rotary base 40. The rotary base 40 has pallet feed mechanisms 10-1 and 10-2 as shown in FIG. 1, 10-2 are preferably provided by giving the length of the center bar 4-2.

The rotary base 40 is arranged concentrically with the center axis 5 (FIG. 2) of the center bar of the pallet 1 and rotates in the range of 90 ° in the lateral and running directions of the pallet. Rotating base 4
Reference numeral 0 has a center base 48, and is engaged with a sprocket gear (not shown) via a speed reducer 46 and a sprocket 47 connected to a drive system (not shown). On the other hand, wheels 41-1, 41-2, 41-3 are arranged on the rotary base 40. The three wheels 41 are composed of a shaft 44 and a protective plate 45, and roll on the rail 43. 42-1 and 42-2 are stoppers.

The rail 43 is provided on the base so as to be concentric with the center base 48, while the rotary base 40 is used for traversing and traveling.
Since it only has to rotate by 0 °, the stoppers 42-1 and 4-4
The rail 43 can be omitted by a length corresponding to a small arc between 2 and 2.

The sprocket gears 53, 54, 55 are provided between the large diameter rolls 11 of the pallet feeding mechanisms 10-1, 10-2, and the speed reducer 13 and the large diameter rolls 11, 11 are connected to the sprocket gears 53, 54, 55. Through sprocket 16
And the driving force of the motor is transmitted to the large-diameter rolls 11, 11.

The structure of the present invention is as described above. Next, the operation will be described.

In the pallet 1 of the present invention, a bar 4 is attached in the longitudinal direction, and the bar 4 is sandwiched between the large diameter roll 11 and the small diameter roll 12, so that the small diameter roll is driven by the driving motor 13 of the large diameter roll 11. The pallet 1 is transferred by friction driving with 12.

That is, in the vertical transfer of the pallet, since the center bar 4-2 is aligned with the bars 4-1 and 4-3, friction driving of large and small rolls of the pallet feeding mechanism is performed regardless of the vertical length of the pallet. Received and transferred sequentially.

The bar 4 is divided into three equal parts and the center bar 4
-2 is rotatably provided in the range of 90 ° in one direction, so that when the rotation base 40 rotates from the vertical direction of the pallet to the horizontal direction, the pallet feeding mechanism 10 holds the center bar 4-2 of the pallet. Rotate in the state.

Further, wheels 6 are provided at four corners of the lower surface of the pallet 1, and the wheels 6 are rotated by the center pedestal 9. Therefore, the wheels 6 are also rotated from the vertical direction to the horizontal direction by the rotation of the center bar. To do.

Since the wheels 6 are formed in a hooked shape and receive the load of the pallet at the edges, the pallet on which the vehicle is loaded can be rotated with a small resistance.

Then, the pallet 1 is traversed by driving the large-diameter roll 11. As the vehicle travels, the center bar is clamped and transferred by the large-diameter roll and the small-diameter roll of the next pallet feeding mechanism.

FIG. 6 shows another example of the present invention, in which lift posts 61, 61 are provided on the terrain 60 of the site to arrange the lifts, and the lift-top circulation type is formed by a combination of three rows to make full use of the terrain 60. Is.

The pallets 1 and 1 are moved by the pallet feed mechanisms 10 and 10 at the corners shown in FIG.
3,43 are circulated and transferred.

That is, in the present invention, the center bar of the pallet is converted 90 ° in one direction by the rotation of the rotary base,
The pallet feeding mechanism provided on the rotary base enables the pallet to be transported in the vertical or horizontal direction.

In the above description, the combination of the large-diameter roll and the small-diameter roll of the pallet feeding mechanism has been described, but a pair of equal-diameter rolls may be used as long as desired friction drive can be obtained.

[0030]

According to the present invention, since the wheels are provided at the four corners of the pallet, the load of the vehicle loaded on the pallet is evenly distributed to the wheels at the four corners, and the pallet feed mechanism and the rotation base of the pallet provided on the rotation base are rotated. With the dynamic mechanism, the pallet can be freely switched between vertical and horizontal traveling directions at the same level.
