2. Description of the Related Art Conventionally, a device of Japanese Patent Application No. 2-130078 has been proposed as a moving device for cyclically moving a plurality of articles such as parcels and furniture arranged side by side to a predetermined position. In this moving device, a winding transport extending in pairs in the longitudinal direction and the width direction of the rectangle is provided at each of the four corners of the substantially rectangular annular transport path at intervals slightly narrower than the length and width of the support base. The apparatus is provided with a direction changing section in which the device is arranged, and the section is provided with an elevating device that relatively reverses the heights of the transport surfaces of the respective winding transport devices in the longitudinal direction and the width direction. The turning of the support base in the turning section of the moving device is carried out as follows. After the supporting table has been loaded into one of the direction changing sections by the longitudinal transport device, the elevating device causes the transport surface of the longitudinal transport device to move relative to the transport surface of the widthwise winding transport device. The support table is lowered and is supported by the widthwise transport surface. Similarly, in the other turning section, the carrying surface of the longitudinal carrying device is lowered to provide the carrying surface of the carrying device in the width direction, whereby the support table moves to the other turning section. .. Next, in the other turning section, the widthwise conveying surface is lowered and simultaneously the longitudinal conveying surface is relatively raised so that the support table is supported by the longitudinal conveying surface. It moves in the longitudinal direction opposite to the carrying-in direction.

Since the moving device requires such a complicated device, the manufacturing cost is high, and the repairing work is troublesome and costly due to the complicated structure.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a plan view schematically showing a support moving device (Z). The support platform moving device (Z) has a substantially rectangular transportation surface entirely surrounded by an outer frame (100), and six regions (A) to (A) formed by equally dividing the transportation surface vertically and horizontally.
(F) is formed, and a rectangular pallet (P) which is placed on these areas and has a size substantially equal to the areas can be moved in the vertical and horizontal directions within the transport surface. In the figure, the pallet (P) is not placed only in the area (C), and the rotating member (R) arranged in the area is visible. The same rotating member (R) is arranged in all of the areas (A) to (F). In the region of the transport surface, a plurality of rotating members (R) capable of rotating in the forward and reverse directions about a horizontal axis are provided in parallel with each other with their axes of rotation inclined with respect to the vertical and horizontal directions.

2 and 3 are enlarged plan views showing the rotary member (R) arranged in the region (C). The rotating member (R) includes one drive motor (M) capable of rotating in the forward and reverse directions,
A main shaft (1) that is rotated by the drive motor and has two rollers (4) at each end, and a roller (4) that is arranged in parallel with the main shaft (1) at a position sandwiching the main shaft back and forth. The driven shafts (2) and (3) and the driving force transmission chains (6), (7) and (8) are provided between the main shaft and the driven shaft. The main axis (1) passes through the center of the surface of the region (C) and is installed at an angle of 45 ° with respect to the vertical or horizontal direction of the surface. One pair of rollers (4) are provided at both ends of the main shaft, and one pair is provided at both ends of each driven shaft. The pair of rollers are provided when the pallet (P) is placed on the area (C) surface. It is arranged at equal distances from the vertical and horizontal edges of the area (C) so as to support the load of the pallet evenly. A bearing (5) for supporting each of the main shaft (1) and the driven shafts (2) and (3) is appropriately arranged at a position along each shaft.

The rotating member (R) may be arranged such that the main shaft and the driven shaft are inclined in the directions shown in FIGS. 2 and 3, or the main shaft and the driven shaft are inclined in the direction shown in FIG. But the same effect can be achieved.

Further, as shown in FIG. 2, in the area (C),
A sensing device is arranged to confirm that the movement of the pallet (P) from another area to the area is completed. That is, the sensing device (9) for confirming the completion of the lateral movement from the area (B) to the area (C) is arranged at the left end of the area (C), and also the area (D). A sensing device (10) for confirming the completion of the movement from the area (C) to the area (C) is arranged at the lower end of the area (C).

Similarly, in other areas, sensing devices for confirming the completion of the movement of the pallet (P) in the horizontal and vertical directions are appropriately provided at the upper and lower ends and the left and right ends of the area. There is. As the sensing device, various known sensors such as a photoelectric switch can be used.

Next, the operation of the rotary member (R) arranged in each region will be described with reference to FIG. In the rotating member (R) in one region, the rotation of the main shaft (1) driven by the drive motor through the chain is indicated by a in FIG.
In the case of the direction, the pallet (P) placed on the rotating member is driven by the plurality of rollers (4) and tries to move in the upper right direction. In this case, if another pallet is arranged in the area adjacent to the right side of the area, by contacting this pallet, the lateral component of the driving force vector by the roller (4) of each shaft is canceled and the pallet becomes Move up. On the contrary, if another pallet is arranged in the area adjacent to the upper side of the area, the vertical component of the driving force vector of the roller (4) of each shaft is canceled by contacting this pallet, and the pallet is Can move to the right.

Similarly, in the rotating member (R) in the area, when the rotation of the main shaft (1) is in the direction b in FIG. 3, the pallet (P) placed on the rotating member is driven by the roller (4). And it tries to move to the lower left direction. In this case, if another pallet is arranged in the area adjacent to the left side of the area, the lateral component of the driving force vector by the plurality of rollers (4) is canceled by coming into contact with this pallet, and the pallet becomes Move down. On the contrary, if another pallet is arranged in the area adjacent to the lower side of the area,
The vertical component of the driving force vector of the plurality of rollers (4) is canceled and the pallet moves leftward.

In this way, the movement of the pallet (P) placed on the rotating member (R) is performed in the rotational directions (a) and (b) of the main shaft and the driven shaft and other adjacent regions. Controlled by another pallet placed, the pallet (P) can move in any of the above, below, left and right directions of the area.

Further, the main shaft and the driven shaft of the rotating member (R) are provided in parallel with each other with an inclination of 45 ° with respect to the longitudinal direction and the lateral direction of the area surface on which the rotating member is provided.
Therefore, the carrying forces obtained by the rotating member are equal to each other in the lateral direction and the longitudinal direction, which is convenient. The inclination can be set in an angle range of 5 ° to 85 °,
When it is set near the upper and lower limits of the range, the driving force is large in one of the vertical direction and the horizontal direction, and the driving force to the other is insufficient.

The movement of the pallet (P) in the area (D) in the support base moving device (Z) of FIG. 1 will be described. By turning on the switch of the control panel provided outside the figure,
The pallet (P) moves along with another pallet with respect to the area (A) facing the loading / unloading port (G) of the luggage.
For example, the area may be moved in the order of D → C → B → A, and further, the pallet may be moved in the order of D → E → B → A. In this way, which movement course to take is programmed in advance in the control device (not shown) so that the movement to the take-out port takes the shortest time.
