  In the mechanical storage facilities as described above, the cost of construction is kept as low as possible, as well as the storage efficiency for storing many loads in as small a space as possible, and the time efficiency for storing or taking out loads in a short time Is generally required. Here, in the case of the tray feed mechanism described in Patent Document 1, the direction of the feed roller mechanism must be changed in order to change the direction of movement of the tray. It will impede efficiency. Further, a bearing is required to reduce friction generated between the feed roller mechanism and the tray when the direction of the feed roller mechanism is changed, which increases the material cost.

  In the pallet conveying apparatus described in Patent Document 2, a motor is required for each pair of the longitudinal feed / guide bidirectional roller and the lateral feed / guide bidirectional roller. The lateral feed / guide bidirectional roller motor does not operate while the pallet is moved in the vertical direction, and the vertical feed / guide bidirectional roller motor does not operate while the pallet is moved in the horizontal direction. That is, each of the motors is dedicated to driving in the vertical direction or the horizontal direction, and the number of operating motors does not always exceed half of the number of installed motors when conveying the pallet. For this reason, conveyance must be performed with a smaller number of motors than the number of installed units, and it is necessary to install a large number of motors with a large power, resulting in an increase in construction cost.

  Also, if the pallet on which the load is placed can be moved not only in the vertical and horizontal directions but also in the oblique direction on the plane, the time required for conveyance may be shortened in some cases, and the time efficiency will be reduced. Is more advantageous. However, neither of the above Patent Documents 1 and 2 allows the pallet (tray) to move obliquely.

  In view of such circumstances, the present invention intends to provide an object transport apparatus capable of improving the time efficiency of transport while reducing the cost with a simple configuration, and a storage facility using the same.

The present invention provides a feed mechanism in which a plurality of feed rollers for placing the object on the upper surface and transporting it along the plane are arranged on a plane formed by arranging a plurality of compartments containing the object vertically and horizontally along the horizontal direction. With
The feed roller is an object conveying device configured as an omnidirectional wheel each having a rotation axis at an oblique angle with respect to the arrangement direction of the sections in the plane ,
At least a part of the feeding mechanism is provided with an independent driving device for each unit, and two feeding rollers configured to rotate at independent directions and speeds are arranged diagonally. A swivel mechanism,
The plane is provided with a support roller for placing the object on an upper surface and allowing movement of the object by rotation, and at least a part of the support roller is configured as an omnidirectional wheel. Is.

  Thus, in this way, the object can be transported on the feed roller by driving the feed roller, and it is necessary to change the direction of the feed roller when switching the transport direction of the object to vertical and horizontal. Absent.

Further, at least a part of the feeding mechanism includes an independent driving device for each unit, and two pairs of the feeding rollers configured to rotate at independent directions and speeds are arranged diagonally. Since it is a feed and turning mechanism, the object placed on the feed and turning mechanism can be turned by driving the drive device.

Furthermore, since the plane is provided with a support roller for placing the object on the top surface and allowing the movement of the object by rotation, the object can be smoothly conveyed by the feeding mechanism, Since at least a part of the support roller is configured as an omnidirectional wheel, the object can be smoothly conveyed and turned in an oblique direction by the feed mechanism and the feed and turn mechanism.

  In the object conveying apparatus according to the present invention, at least a part of the feeding mechanism includes two pairs of the feeding rollers arranged diagonally to each other, and the two pairs of feeding rollers are parallel or coincident with each other. It is preferable that the drive device provided for each pair has a rotation shaft that is configured to rotate at the same speed in the same direction for each pair. The required output can be reduced, and the number of installed drive units can be minimized.

  The present invention also relates to a storage facility comprising the object conveying device described above.

  The storage facility of the present invention can be configured as a parking lot where a pallet on which a vehicle is placed is conveyed by the feed roller.

  According to the object conveying apparatus and the storage facility using the same of the present invention, it is possible to achieve an excellent effect that the time efficiency of conveyance can be improved while reducing the cost with a simple configuration.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIGS. 1-6 shows the reference example relevant to this invention, Comprising: The part which attached | subjected the code | symbol same as FIG. 12 in the figure represents the same thing.

As shown in FIG. 1, the object conveying apparatus of this reference example includes a plurality of support rollers 9 and a plurality of feed rollers 10 on a support structure (frame) 8 laid in a cross-beam shape along the plane 2 of the storage facility 1. The feed mechanism 11 provided is provided. On the support roller 9 and the feed roller 10, a pallet 3 on which a load of a vehicle or the like is loaded or an empty pallet 3 on which a load is not loaded is supported (for convenience of explanation, the load placed on the pallet 3 is Basically, not shown, the pallet 3 on which the load is placed and the empty pallet 3 are treated equally without distinction as objects to be transported).

  The plane 2 is formed by arranging a plurality of sections 2a for storing one object (one pallet 3) vertically and horizontally along the horizontal direction, and the frame 8 is configured with one section 2a as one unit. Yes. The frame 8 constituting one section 2a includes a support frame 8d extending in the vertical direction inside a rectangular frame 8c including a pair of vertical frames 8a and 8a and a pair of horizontal frames 8b and 8b.

  Here, a case where a frame 8c composed of a pair of vertical frames 8a and 8a and a pair of horizontal frames 8b and 8b is used as one unit of the frame 8 is illustrated, but the configuration of the frame (support structure) 8 is shown here. It is not limited. For example, the vertical frame 8a and the horizontal frame 8b constituting the frame 8c may be shared or omitted at least partially between the adjacent sections 2a, and conversely, a larger number of frames. It may consist of. Alternatively, the frame 8 does not have to be configured in a cross beam shape. Furthermore, the support structure 8 is not limited to the frame, and may be, for example, a floor surface formed of a plate-like member or a combination of the frame and the floor surface. It is sufficient that the pallet 3 as an object to be conveyed can be supported on the plane 2 via the support roller 9 and the feed roller 10.

  Although the pallet 3 is shown as a rectangular shape here, the shape of the pallet 3 is not limited to this. For example, it may be a polygon other than a rectangle or a circle. In addition, various shapes can be taken according to various circumstances such as the shape of the loaded load and the shape of the plane 2.

  Alternatively, the pallet 3 itself is not necessarily required depending on the configuration and use of the storage facility 1. The object conveying device of the present invention is not limited to a parking lot, and can be installed in various storage facilities 1 other than a warehouse, and a load that is conveyed and stored is not necessarily a vehicle. If the load to be transported has a shape having a flat surface on the lower surface, such as a rectangular parallelepiped container, the pallet 3 is omitted, and the load to be transported is placed directly on the upper surface of the object transport device. May be.

  On the support frame 8d, one feeding mechanism 11 is provided for each section 2a. Each feed mechanism 11 includes four feed rollers 10 (10a, 10b, 10c, 10d), and the four feed rollers 10a, 10b, 10c, 10d are respectively located at the upper right side of the rectangular frame 8c. They are arranged symmetrically in the lower right, upper left, and lower left.

In the feed mechanism 11 shown here, the rotation axes of the upper right feed roller 10a and the lower left feed roller 10d that form diagonal lines, and the lower right feed roller 10b and the upper left feed roller 10c coincide with each other. The rotation shafts of the feed rollers 10a and 10d and the rotation shafts of the feed rollers 10b and 10c have an oblique angle with respect to the arrangement direction of the sections 2a. In the example shown here, the angles θ ₁ and θ ₂ formed by the rotation axes of the pair of feed rollers 10a and 10d and the rotation axes of the pair of feed rollers 10b and 10c with respect to the vertical arrangement direction of the sections 2a are respectively The rotation axes of the feed rollers 10a and 10d and the rotation axes of the feed rollers 10b and 10c are orthogonal to each other.

  The upper right feed roller 10a is provided with a motor 12a as a drive device. The upper right feed roller 10a and the lower left feed roller 10d are connected by a shaft 13 as a power transmission mechanism that forms a rotation axis of the feed roller 10a and the feed roller 10d, and the drive of the motor 12a is transmitted through the shaft 13. By doing so, the feed rollers 10a and 10d can be simultaneously rotated in the same direction and at the same speed.

  The lower right feed roller 10b is provided with a motor 12b as a driving device. The lower right feed roller 10b and the upper left feed roller 10c have power transmissions including three shafts 14a, 14b, 14c. They are connected via a mechanism 14. Of the three shafts, the shaft 14b constitutes the rotation axis of the lower right feed roller 10b, and the shaft 14c constitutes the rotation axis of the upper left feed roller 10c. The shaft 14b and the shaft 14c are connected to both ends of the shaft 14a via sprockets 14d and 14d as components of the power transmission mechanism 14 and a chain 14e, respectively. In this way, the power transmission mechanism 14 bypasses the shaft 13 which is the other power transmission mechanism and connects the feed roller 10b and the feed roller 10c. Then, by transmitting the drive of the motor 12b through the shafts 14b, 14a, and 14c, the feed rollers 10b and 10c can be simultaneously rotated in the same direction and at the same speed.

  Each feed roller 10 (10a, 10b, 10c, 10d) is configured as an omnidirectional wheel 10 as shown in FIG. The “omnidirectional wheel” here refers to a wheel of a known mechanism called by name such as Omni Wheel (registered trademark) described in Patent Document 2 or Mecanum Wheel, for example, as shown in FIG. A plurality of small rollers 10f having a circumferential axis are provided on the outer periphery of the roller 10e. An object in contact with the omnidirectional wheel 10 on the outer periphery of the roller 10e can move in a direction orthogonal to the axial direction with respect to the omnidirectional wheel 10 by rotation of the roller 10e about the roller shaft 10g, and at the same time, a small roller 10f. The movement in the axial direction is also allowed by the rotation of.

As shown in FIG. 1, support rollers 9 that support the pallet 3 while allowing the movement of the pallet 3 along the plane 2 are disposed between the sections 2 a in the frame 8. In the case of this reference example , the support roller 9 is configured as a general roller that is not an omnidirectional wheel like the feed roller 10 illustrated in FIG. 2, but may be configured as an omnidirectional wheel. Or it can also be set as the structure which accept | permits the movement of the pallet 3 by rolling of the said spherical body, providing a spherical body and supporting the palette 3. FIG. However, the cost for installing the support roller 9 can be reduced by using a general roller.

  The support rollers 9 disposed between the adjacent sections 2a and 2a have axes in a direction orthogonal to the arrangement direction of the adjacent sections 2a and 2a, respectively. For example, the support roller 9 between the sections 2a and 2a arranged in the vertical direction has an axis parallel to the horizontal frame 8b, and the support roller 9 between the sections 2a and 2a arranged in the horizontal direction is parallel to the vertical frame 8a. It has a special axis. The support roller 9 is also provided between the elevating part 6 and the section 2 a of the plane 2 adjacent to the elevating part 6. Unlike the above-described feed roller 10, the support roller 9 is configured as a free roller that does not have a driving device such as motors 12a and 12b.

The arrangement and other configurations of the feed rollers 10a, 10b, 10c, and 10d in the feed mechanism 11 are not limited to the example shown in FIG. The direction of the rotation axis of each of the feed rollers 10a, 10b, 10c, and 10d may not be an angle of 45 degrees with respect to the vertical direction, and the rotation axis is between the feed rollers 10a and 10d and 10b and 10c that form diagonal lines. For example, they may be arranged as shown in FIG. In the feed mechanism 11 shown here, the angles θ ₁ and θ ₂ formed by the rotation axes of the feed rollers 10a and 10d and 10b and 10c with respect to the vertical direction are smaller than 45 degrees, and between the feed rollers 10a and 10d, And between 10b and 10c, the axes of rotation are parallel to each other but are not coincident.

  In the feed mechanism 11 of FIG. 3, the power transmission mechanism 15 is formed by connecting a shaft 15a that forms the rotation axis of the feed roller 10a and a shaft 15d that forms the rotation axis of the feed roller 10d with shafts 15b and 15c. The shaft 15a and the shaft 15b are connected in parallel to each other via a pair of sprockets 15e and 15e and a chain 15f. The shaft 15b and the shaft 15d are connected to both ends of the shaft 15c via a pair of gears 15g and 15g, respectively. The shaft 15c is orthogonal to the shafts 15b and 15d.

  On the other hand, the power transmission mechanism 16 includes a shaft 16a that connects a shaft 16b that forms the rotation axis of the feed roller 10b and a shaft 16c that forms the rotation axis of the feed roller 10c. The shaft 16b and the shaft 16c It is connected to both ends of 16a via a pair of gears 16d and 16d, respectively. The shaft 16a is orthogonal to the shafts 16b and 16c.

  Thus, the feed roller 10 a and the feed roller 10 d are connected by the power transmission mechanism 15, and the feed roller 10 b and the feed roller 10 c are connected by the power transmission mechanism 16 so that the power transmission mechanism 15 bypasses the power transmission mechanism 16. Then, by transmitting the drive of the motors 12a and 12b via the power transmission mechanisms 15 and 16, respectively, the feed rollers 10a and 10d and the feed rollers 10b and 10c can be simultaneously rotated in the same direction and at the same speed. It can be done.

For example, the feed mechanism 11 may be configured as shown in FIG. In the example shown in FIG. 4, the angles θ ₁ and θ ₂ formed by the axes of the feed rollers 10 with respect to the vertical direction are 45 degrees, but the feed rollers 10a and 10d and the links 10b and 10c are connected. The power transmission mechanisms 17 and 18 are bent 90 degrees inward in the longitudinal direction at both ends.

  The power transmission mechanism 17 is connected to a shaft 17b between a shaft 17a that forms a rotation axis of the feed roller 10a and a shaft 17d that forms a rotation axis of the feed roller 10d, and both ends of the shaft 17b are respectively connected to a pair of gears 17c. , 17c and the shafts 17a, 17d. The shaft 17b is orthogonal to the shafts 17a and 17d. The motor 12a is attached to the shaft 17b, and the feed rollers 10a and 10d can be simultaneously rotated at the same speed in the same direction by driving the motor 12a.

  The power transmission mechanism 18 is formed by connecting shafts 18d, 18a, and 18e between a shaft 18b that forms the rotation axis of the feed roller 10b and a shaft 18c that forms the rotation axis of the feed roller 10c. The shafts 18b and 18d and the shafts 18c and 18e are connected via a pair of gears 18f and 18f, respectively, and the shafts 18b and 18d and the shafts 18c and 18e are orthogonal to each other. The shafts 18d and 18e are connected to both ends of the shaft 18a via sprockets 18g and 18g and a chain 18h, respectively. In this way, the power transmission mechanism 18 connects the feed rollers 10b and 10c while bypassing the power transmission mechanism 17. The motor 12b is attached to the shaft 18d, and the feed rollers 10b and 10c can be simultaneously rotated in the same direction at the same speed by driving the motor 12b.

  Due to the power transmission mechanisms 17 and 18 having such a configuration, in the example shown in FIG. 4, the feed rollers 10a, 10b, 10c, and 10d and the motors 12a and 12b of the frame 8c are compared with the example shown in FIG. It is arranged more inside in the vertical direction. In this way, even if the vertical width of the section 2a or the pallet 3 (see FIG. 1) is relatively small, the feed rollers 10a, 10b, 10c, 10d and the motors 12a, 12b are arranged in the section 2a. can do.

  Thus, in the feed mechanism 11, the feed roller 10 and the driving devices 12a and 12b can be arranged in various ways depending on the shape and size of the section 2a or the pallet 3, and the power transmission mechanism for connecting the feed rollers 10 to each other. However, it can take various forms depending on the arrangement of the feed roller 10 and the driving devices 12a and 12b. Further, in FIGS. 1, 3 and 4, four feed rollers 10 (10a, 10b, 10c, 10d) and two drive devices (motors) (12a, 12b) per feed mechanism 11 are used. However, the number of these components is not limited to this. For example, the number of feed rollers 10 may be increased, and the number of drive devices may be increased accordingly. The number of feed rollers 10 driven by a single drive device is also two in the example shown in FIGS. 1, 3, and 4, but it may be more or less.

  1, 3, and 4, the feed mechanism 11 including the feed roller 10 and the driving devices (motors) 12 a and 12 b is described as an example in which one set is provided for each section 2 a. Further, one or more sets of feeding mechanisms 11 may be provided for each section 2a. The number and arrangement of the support rollers 9 are not limited to those shown in FIG. The pallet 3 should just be arrange | positioned by the support roller 9 and the feed roller 10 so that it may convey appropriately along the plane 2 so that it may mention later. For example, as shown in FIG. 6, the support roller 9 may not be arranged between the horizontally adjacent sections 2a, but a feeding mechanism 11 may be added instead.

Next, the operation of the above reference example will be described. In the case of this reference example , since the whole structure of the storage facility (parking lot) 1 is the same as that of the conventional example shown in FIG. 12, the parts common to the conventional example will be described using the reference numerals in FIG.

  Similar to the conventional example shown in FIG. 12, the vehicle 4 is placed on the pallet 3 on the turntable 7 provided on the boarding surface 1 a of the elevating unit 6, and the direction is changed by turning the turntable 7. The elevating unit 6 is lowered to the storage plane 2 by a lift (not shown). When arriving at the storage plane 2, the pallet 3 is moved from the elevating unit 6 to the plane 2 by a feed mechanism provided in a lift (not shown), and is further transported in the plane 2 to the storage section 2 a.

  At this time, the pallet 3 is first fed in the vertical direction from the elevating unit 6 toward the adjacent section 2a by a lift feed mechanism (not shown). Thereafter, as shown in FIG. 5, between the adjacent sections 2 a, the sections are transported along the plane 2 one by one in the vertical or horizontal direction by the operation of the feed mechanism 11.

  The conveying operation of the pallet 3 by the feeding mechanism 11 will be described with reference to FIG. When the feed mechanism 11 is configured as in the example of FIG. 1, for example, when it is desired to transport the pallet 3 downward in the figure, the motor 12 a of the feed mechanism 11 on which the pallet 3 is placed is operated to feed the pallet 3. The rollers 10a and 10d are driven in a direction to move the pallet 3 to the lower right in the figure, and at the same time, the motor 12b is operated at the same speed as the motor 12a to move the feed rollers 10b and 10c in the direction to move the pallet 3 to the lower left in the figure. To drive. At this time, for the feed rollers 10a and 10d, the pallet 3 tries to move in the drive direction of the feed rollers 10a and 10d (lower right in the figure) and at the same time drives the feed rollers 10a and 10d by driving the feed rollers 10b and 10c. It also tries to move in a direction perpendicular to the direction (lower left in the figure). Here, since the feed rollers 10a and 10d are configured as omnidirectional wheels 10 as shown in FIG. 2, the pallet 3 is moved to the lower right in the figure by driving the feed rollers 10a and 10d, and simultaneously to the lower left in the figure. Movement is also acceptable. Similarly, for the feed rollers 10b and 10c, the pallet 3 tries to move in the drive direction of the feed rollers 10b and 10c (lower left in the figure), and at the same time, the drive direction of the feed rollers 10b and 10c is driven by the feed rollers 10a and 10d. It tries to move in the direction perpendicular to the bottom (lower right in the figure). Since the feed rollers 10b and 10c are also configured as omnidirectional wheels, the pallet 3 is moved to the lower left in the figure by driving the feed rollers 10b and 10c, and at the same time, the pallet 3 is allowed to move to the lower right in the figure. As a result, the pallet 3 is a direction in which the driving roller 10a, 10d driving direction vector (lower right in the figure) and the driving roller 10b, 10c driving direction vector (lower left in the figure) are combined. Move to.

  Similarly, if the feed rollers 10a and 10d are driven in the direction to move the pallet 3 to the lower right in the figure, and the feed rollers 10b and 10c are driven in the direction to move the pallet 3 to the upper right in the figure, the pallet 3 is moved in the right direction. Moving. The feed rollers 10a and 10d are driven in the direction to move the pallet 3 to the upper left in the figure. At the same time, if the feed rollers 10b and 10c are driven in the direction to move the pallet 3 to the lower left in the figure, the pallet 3 moves to the left. The feed rollers 10a and 10d are driven in a direction to move the pallet 3 to the upper left in the figure. At the same time, if the feed rollers 10b and 10c are driven in a direction to move the pallet 3 to the upper right in the figure, the pallet 3 moves upward.

Here, when the feed roller 10 is arranged as shown in FIG. 1, FIG. 3, or FIG. 4, the angle θ ₁ formed by the central axis of the feed rollers 10a, 10d with respect to the vertical direction, and 10b, 10c. Are equal to each other in the angle θ ₂ formed with respect to the longitudinal direction. Therefore, in the conveyance in the vertical and horizontal directions as described above, if the motors 12a and 12b are driven at the same speed, the pallet 3 can be correctly moved vertically and horizontally between the sections 2a.

In the example shown in FIGS. 1 and 4, the angles θ ₁ and θ ₂ are both 45 degrees, and therefore the vertical conveyance speed and the horizontal conveyance speed of the pallet 3 are driven by the motors 12a and 12b. It is equal if the speed is the same. In the example shown in FIG. 3, the angles θ ₁ and θ ₂ are smaller than 45 degrees. Therefore, when the driving speeds of the motors 12 a and 12 b are the same, the horizontal transport speed is higher than the vertical transport. growing.

  During conveyance on the plane 2, the pallet 3 moves while being supported by the feed roller 10 and the support roller 9 located on the lower surface of the pallet 3. As described above, since the support roller 9 has a rotation axis perpendicular to the direction in which the adjacent sections 2a and 2a are arranged, the movement is supported as long as the pallet 3 moves vertically and horizontally between the sections 2a. Allowed by the rotation of the roller 9, the pallet 3 can move smoothly while being supported by the upper surface of the support roller 9.

  When the movement of the pallet 3 between the sections 2a and 2a proceeds, one end of the pallet 3 is separated from the upper surface of the feed roller 10 of the feed mechanism 11 that has supported and conveyed the pallet 3 until then. The other end of the pallet 3 reaches the upper surface of the feed roller 10 of another feed mechanism 11. Accordingly, the conveyance of the pallet 3 can be smoothly continued by successively taking over the driving of the feed roller 10 as described above between the feed mechanisms 11.

  In the case of the arrangement as shown in FIG. 6, a feed mechanism 11 is provided instead of the support roller 9 at the center in the left-right direction in the figure. When the pallet 3 is transported, these feeding mechanisms 11 support the pallet 3 in place of the support rollers 9 and operate so as to transport the pallet 3, so that stable transport can be performed.

As described above, in this reference example , the pallet 3 is transported by driving the feed rollers 10 provided to each of the four feed mechanisms 11 arranged on the plane 2. Since the drive devices (motors) 12a, 12b for driving the four feed rollers 10 are driven in cooperation, compared to the case where the drive devices are respectively provided in the vertical direction or the horizontal direction, Each of the driving devices (motors) 12a and 12b can have a small output. Each feed mechanism 11 is provided with power transmission mechanisms 13, 14, 15, 16, 17, 18 for connecting a pair of diagonal feed rollers (10a and 10d and 10b and 10c) to transmit power. Since each feed roller 10 is driven pair by pair, the number of installed drive devices can be reduced as compared with the case where a drive device is attached to each feed roller 10. Furthermore, it is not necessary to change the direction of the feed roller 10 when switching the transport direction, and it is only necessary to switch the rotation direction of the motors 12a and 12b.

As described above, in the present reference example , a plane formed by arranging a plurality of compartments 2a for accommodating an object (the pallet 3 and the pallet 3 on which the vehicle 4 as a load is placed) arranged vertically and horizontally along the horizontal direction. 2 is provided with a feed mechanism 11 in which a plurality of feed rollers 10 for placing the object on the upper surface and transporting it along the plane 2 are arranged. The feed roller 10 is inclined with respect to the arrangement direction of the sections 2a on the plane 2 Since it is configured as an omnidirectional wheel 10 each having an angular rotation axis, the object can be transported on the feed roller 10 by driving the feed roller 10, and in switching the transport direction of the object vertically and horizontally, There is no need to change the direction of the feed roller 10.

In this reference example , at least a part of the feed mechanism 11 includes two pairs of feed rollers 10a, 10d and 10b, 10c arranged diagonally to each other, and the two pairs of feed rollers 10a, 10d. And 10b, 10c have rotating shafts that are parallel or coincident with each other, and are rotated at the same speed in the same direction for each pair by drive devices (motors) 12a, 12b provided for each pair. Since it is comprised in this way, the output required for drive device 12a, 12b can be made small, and the installation number of drive devices 12a, 12b can be made into the minimum.

Further, in this reference example , since the support roller 9 is provided on the plane 2 to place the object on the upper surface and allow the movement of the object by rotation, the object is smoothly conveyed by the feed mechanism 11. be able to.

Therefore, according to the present reference example , it is possible to improve the time efficiency of conveyance while reducing the cost with a simple configuration.

FIGS. 7 to 11 show an embodiment of the present invention. In the drawings, the same reference numerals as those in FIGS. 1 to 6 and FIG.

In the case of the present embodiment , as shown in FIG. 7, in addition to the function of transporting the pallet 3, some of the feeding mechanisms in the section 2 a constituting the plane 2 of the storage facility (parking lot) 1 have a function of turning. The feeding and turning mechanism 19 is configured.

  As shown in FIG. 8, the feed mechanism (feed / swivel mechanism) 19 is the same as the feed mechanism 11 described above with respect to the arrangement of the four feed rollers 10a, 10b, 10c, and 10d (see FIG. 1). No power transmission mechanism is provided between the rollers 10, and each feed roller 10 is provided with motors 12 a, 12 b, 12 c, 12 d as independent drive devices for each unit. This is different from the feed mechanism 11 in that the feed rollers 10 are driven independently of each other.

In the present embodiment , for example, as shown in FIG. 7, in each plane 2 of the parking lot 1, it is sent to a section 2 a that is vertically adjacent to the lift 6 and a section 2 a that is vertically adjacent to the section 2 a. Instead of the mechanism 11, a feeding and turning mechanism 19 is provided, and the feeding mechanism 11 is provided in the other section 2a.

In this embodiment , the support roller is not an ordinary roller but includes an omnidirectional wheel 20 having the same configuration as the feed roller 10 (see FIG. 2). The omnidirectional wheel 20 as the support roller is disposed between the sections 2a and between the sections 2a and the elevating unit 6 in a direction in which the rotation axis has an oblique angle with respect to the vertical direction.

When the support roller 20 is configured as an omnidirectional wheel in this way, the installation direction and position of the support roller 20 are not limited to the configuration illustrated here. For example, as in the above reference example (see FIG. 1), it may be installed in a direction having a rotation axis in the vertical direction or the horizontal direction, or installed in a place other than between the sections 2a and 2a. Also good. The pallet 3 should just be arrange | positioned so that the support roller 20 and the feed roller 10 may be appropriately conveyed on the support roller 20 and the feed roller 10 so that it may mention later. Similarly to the description of the support roller 9 of the reference example , the support roller 20 may be configured to allow the movement of the pallet 3 by rolling the sphere while supporting the pallet 3 with the sphere. Is possible.

The arrangement of the feed mechanism 11, the support roller 20, and the feed / swivel mechanism 19 is not limited to the example shown here. For example, as described with reference to FIG. 6 in the above reference example , the support roller 20 (see FIG. 7) is not disposed between the horizontally adjacent compartments 2a. Instead, the feed mechanism 11 and the feed / swivel mechanism 19 ( 7), and one or more pairs of feed mechanisms 11 and feed / swivel mechanisms 19 (see FIG. 7) may be provided per section 2a.

Next, the operation of this embodiment will be described. Also in the present embodiment , the configuration of the object transporting device and the storage facility 1 is generally the same as the reference example shown in FIGS. 1 to 6, and there are parts that are also common to the conventional example shown in FIG. Will be described with reference to FIGS. 1 to 6 and FIG.

In this embodiment , since the support roller 20 is configured as an omnidirectional wheel, the pallet 3 can be moved in an oblique direction between the sections 2a and 2a. For example, as shown in FIG. 9, let us consider a case where the pallet 3 is transported from the lower left section 2a toward the upper right section 2a. Here, as explained in the above reference example , for example , the pallet 3 located in the lower left section 2a is transported in the horizontal direction and moved to the lower right section 2a, and then transported in the vertical direction and then transferred to the upper right. Of course, it is possible to move the pallet 3 by vertical and horizontal conveyances, such as moving to the section 2a, but if there is sufficient room in the section 2a (that is, in this case, the upper right section 2a is moved). In addition, the pallet 3 is not positioned in the lower right and upper left sections 2a, and is an empty section 5 (see FIG. 12)), and the upper right section 2a from the lower left section 2a (position A). The pallet 3 can be moved in a straight line in an oblique direction toward (position C).

In the example shown here, the feed mechanism 11 arranged in each section 2a has the same configuration as the feed mechanism 11 (see FIG. 1) described in the above reference example , and the rotation axis of each feed roller 10 is the same. It has an angle of 45 degrees with respect to the vertical direction. When such a feed mechanism 11 moves the pallet 3 obliquely from the position A toward the position C, first, among the feed mechanisms 11 in the lower left section 2a, the feed rollers located at the upper right and the lower left. 10a and 10d are driven at a low speed in the direction of moving the pallet 3 to the lower right, and the feed rollers 10b and 10c positioned at the lower right and the upper left are driven at a high speed in the direction of moving the pallet 3 to the upper right. Then, the moving direction of the pallet 3 is a vector direction obtained by combining the driving speed vectors of the feeding rollers 10a and 10d and the driving speed vector of the feeding rollers 10b and 10c, and the pallet 3 is moved from the A position to the C position. Start moving toward.

  When the movement of the pallet 3 proceeds to some extent, the feeding mechanism 11 in the lower left section 2a moves away from the lower surface of the pallet 3, and the pallet 3 reaches the upper surface of the feeding mechanism 11 in the other section 2a. For example, in the position B, the feed rollers 10a and 10c in the lower left section 2a and the feed rollers 10b and 10c in the upper left section 2a are located on the lower surface of the pallet 3. In this way, when the position of the pallet 3 extends over a plurality of feed mechanisms 11, the feed rollers 10 of the feed mechanisms 11 on which the pallet 3 is placed may be operated simultaneously as described above. In this way, by sequentially operating the feed mechanism 11 on the path through which the pallet 3 passes, the pallet 3 is conveyed in a straight line in the oblique direction, and the movement time is shorter than that in the case of conveying in the vertical and horizontal directions. It will be over.

Here, in the case of the present embodiment , the support roller 20 provided between the sections 2a is configured as an omnidirectional wheel (see FIG. 2), and the movement of the pallet 3 placed on the upper surface is irrespective of its direction. Allow. Therefore, the support roller 20 supports the pallet 3 conveyed in the oblique direction without hindering its movement, and the pallet 3 can be smoothly moved in the oblique direction.

  The movement in the oblique direction shown here is merely an example. For example, when the pallet 3 is to be moved diagonally by one section horizontally and three sections vertically, or when the aspect ratio of the pallet 3 or section 2a is When the direction to be moved is different from that described with reference to FIG. 9, the rotational speed and the rotational direction of each feed roller 10 are appropriately adjusted, and the moving direction of the pallet 3 as a composition of those vectors. Needless to say, it is only necessary to control. In some cases, when the pallet 3 is transported to the target section 2a, the movement in the oblique direction and the movement in the vertical and horizontal directions may be combined. For example, when it is desired to transport the pallet 3 from the lower left section 2a to the upper right section 2a in FIG. 9, the upper right and lower left feed rollers 10a and 10d of the feed mechanism 11 are not driven in the lower left section 2a. When the pallet 3 is moved to the upper right by driving the feed rollers 10b and 10c, the pallet 3 moves in the upper right direction at an angle of 45 degrees with respect to the vertical direction. Thereafter, if the feed mechanism 11 of the upper left section 2a or the upper right section 2a is operated to move the pallet 3 to the right, the pallet 3 can be moved to the upper right section 2a. Also in this case, the time required for conveyance is shorter than that in the case of conveyance by only vertical and horizontal movements.

Further, even when the feed mechanism 11 is configured as shown in FIGS. 3 and 4, it is possible to convey in an oblique direction by an operation according to the above. For example, in the case of the feed mechanism 11 shown in FIG. 3, the angles θ ₁ and θ ₂ formed by the feed rollers 10 with respect to the vertical direction are not 45 degrees, but here, the length of the section 2a in the vertical direction When the thickness is a and the lateral length is b, the following formula [Equation 1]
tan θ ₁ = tan θ ₂ = a / b
If the angles θ ₁ and θ ₂ are set to the sizes defined by the above, the pallet 3 can be moved from the lower left section 2a to the upper right section 2a only by driving only the lower right and upper left feed rollers 10b and 10c. It can be conveyed in a straight line, and drive control is simple when moving in an oblique direction. When it is desired to move the pallet 3 at an angle other than this, for example, when the pallet 3 is to be moved obliquely by one section horizontally and three sections vertically, the upper right and lower left feed rollers 10a and 10d and the lower right and upper left feeds. Similar to the case of the feed mechanism 11 shown in FIGS. 1 and 9, the rollers 10b and 10c may be coordinated while appropriately adjusting their driving speeds.

In the case of the feed mechanism 11 shown in FIG. 4, the angles θ ₁ and θ ₂ formed by the feed rollers 10 with respect to the vertical direction are 45 degrees. Are shifted by 90 degrees. For example, when the pallet 3 is to be transported in an oblique direction from the lower left compartment 2a to the upper right compartment 2a in the same manner as described above, the lower left corner is opposite to that shown in FIG. Among the feed mechanisms 11 located in the section 2a, the feed rollers 10a and 10d are driven at a high speed in the direction of transporting the pallet 3 to the upper right, and the feed rollers 10b and 10c are small in the direction of transporting the pallet 3 to the lower right. What is necessary is just to drive at speed.

In this embodiment , the feed / swivel mechanism 19 is provided in place of the feed mechanism 11 in a part of the section 2 a in the plane 2, but the feed / swivel mechanism 19 is also the same as the feed mechanism 11. The pallet 3 can be conveyed. Unlike the feed mechanism 11, the feed and swivel mechanism 19 does not include a power transmission mechanism and does not transmit power between the feed rollers 10, but feed rollers arranged diagonally. If the movements are synchronized between the motors 12 a and 12 d and the motors 12 b and 12 c provided in the motor 10, similar to the feeding mechanism 11, the conveyance in the vertical and horizontal directions and the oblique direction can be performed.

In addition, here, the arrangement including one feeding mechanism 11 or feeding and turning mechanism 19 per one section 2a has been described as an example , but in the same manner as described with reference to FIG. 6 of the reference example , the feeding mechanism 11 or The number of the feed / swivel mechanism 19 installed in the section 2a may be larger than this. In such a case, the pallet 3 can be transported in the same manner by operating the plurality of feed mechanisms 11 or feed / swivel mechanisms 19 on which the pallet 3 is placed on the upper surface in the same manner as described above.

Further, in the present embodiment , in addition to the transport by the feed mechanism 11 and the feed / swivel mechanism 19 as described above, the pallet 3 is swung by the operation of the feed / swivel mechanism 19 provided in a part of the sections 2a. Can be done. Referring to FIG. 8, the upper right feed roller 10a is driven in a direction to move the pallet 3 placed on the upper surface to the lower right, and the lower right feed roller 10b is moved to the lower left. When driven in the direction to move, the lower left feed roller 10d is driven in the direction to move the pallet 3 to the upper left, and the upper left feed roller 10c is driven in the direction to move the pallet 3 to the upper right, the feed rollers 10a and 10b , 10c, 10d are pivoted clockwise. Conversely, the upper right feed roller 10a is driven in the direction to move the pallet 3 to the upper left, the lower right feed roller 10b is driven in the direction to move the pallet 3 to the upper right, and the lower left feed roller 10d is moved to the pallet. 3 is driven in the direction of moving to the lower right, and the upper left feed roller 10c is driven in the direction of moving the pallet 3 to the lower left, the pallet 3 on the feed rollers 10a, 10b, 10c, and 10d is rotated counterclockwise. Turn. Thus, in the feed and swivel mechanism 19, the feed rollers 10 can be driven independently from each other, so that the diagonal feed rollers 10 (10 a and 10 d, 10 b and 10 c) are driven in opposite directions. Thus, the pallet 3 can be turned.

Such a movement of turning the pallet 3 may be executed in the lift by installing the feeding and turning mechanism 19 as described above on the lift of the elevating unit 6 (see FIG. 7) (not shown). In the case of the present embodiment , as shown by the phantom line in FIG. 7, the feeding and turning mechanism 19 installed in the section 2 a adjacent to the elevating part 6 is executed. At this time, with the turning, the end of the pallet 3 reaches the outside of the section 2a where the feed and turning mechanism 19 for driving the turning of the pallet 3 is installed, but the support roller provided around the section 2a. Since 20 is configured as an omnidirectional wheel, even if the pallet 3 reaches the support roller 20, the support roller 20 does not prevent the pallet 3 from turning. The section 2a adjacent to the section 2a in which the feed / swivel mechanism 19 for driving the turn is installed is also provided with the same feed / turn mechanism 19, and the feed rollers 10 of the feed / turn mechanism 19 are mutually connected. Since it is configured as an omnidirectional wheel that is driven independently, the feed roller 10 does not prevent the pallet 3 from turning. When the pallet 3 is turned, the feed roller 10 of the feed / turning mechanism 19 is operated in a plurality of adjacent sections 2a, and the pallet 3 may be turned in cooperation with the plurality of feed / turning mechanisms 19. good.

  Here, as described above, the feed and swivel mechanism 19 is provided in two compartments 2a that are vertically adjacent to the elevating unit 6, and performs the above-described rotation operation in a space of about three compartments 2a. However, this is because the shape of the pallet 3 as shown in the present embodiment requires a minimum area for three pallets 3 to turn the pallet 3. If the shape of the pallet 3 and the arrangement of the compartments 2a and the like are different, the area required for the rotational operation or the number of compartments 2a may be different from that shown here. The number and arrangement of the compartments 2a to be provided with the mechanism 19 can be variously changed.

Thus, in the storage facility (parking lot) 1 according to the present embodiment , the pallet 3 can be turned in the elevating part 6 or the plane 2. For this reason, unlike the prior art example and the reference example (see FIGS. 12 and 1), it is not necessary to turn the pallet 3 on the loading surface at the time of loading / unloading, and time for loading / unloading can be saved. For example, in the case of the conventional example shown in FIG. 12, when the vehicle 4 is received, the vehicle 4 is turned on the turntable 7 of the boarding surface 1a and then sent to the lift unit 6 and the storage destination plane 2. Therefore, when it is desired to continuously store a plurality of vehicles 4, the vehicle 4 is turned and then sent to the elevating unit 6 and the storage plane 2 and it takes time for each vehicle to turn. On the other hand, if the pallet 3 is turned at a place other than the boarding surface as in the present embodiment , for example, after the vehicle is moved in from the boarding surface, the elevating unit 6 is not turned. Or, the vehicle can be sent to the storage plane 2 and the next vehicle can be stored while the vehicle is turning on the lift 6 or the plane 2. In this way, the waiting time required for loading and unloading can be shortened.

  In addition, it is possible to further improve the time efficiency by simultaneously performing the turning and movement of the pallet 3 in the plane 2. For example, FIG. 10 shows an example in which the feeding and turning mechanism 19 (not shown in FIG. 10) is provided in three sections 2a adjacent in the vertical direction. By cooperating the three feeding and swiveling mechanisms 19 provided in the three sections 2a, the pallet 3 can be moved sequentially along a path as indicated by AG in the drawing. While the pallet 3 moves from the section 2a (A position) located in the upper part to the section 2a (G position) located in the lower part in the figure, the pallet 3 turns and the direction of the pallet 3 is reversed. Yes. Thus, if it is made to turn simultaneously during conveyance of the pallet 3, the time concerning turning can be saved.

Making the pallet 3 turnable on the plane 2 by installing the feeding and turning mechanism 19 leads to an improvement in the degree of freedom in layout in the storage facility (parking lot) 1. In other words, depending on the shape of the pallet 3, a large space is required for turning the pallet 3 (in the example shown here, three sections 2a), but the feed and turning mechanism 19 is fed to the plane 2 as in this embodiment. If the pallet 3 is swung on the plane 2, the pallet 3 can be swung even if the space for the loading surface 1 a (see FIG. 12) and the lifting / lowering unit 6 is small. There is no problem even if a large space cannot be secured on the boarding surface 1a and the elevating part 6 when installing the car park 1).

  For example, as shown in FIG. 11, even if there are pillars or other obstacles in the plane 2, there are cases where it is possible to cope by turning the pallet 3 and changing the direction. In the example shown here, the pallet 3 moved from the elevating part 6 to the plane 2 is swung by the feed and swivel mechanism 19 to change the direction from the horizontal direction to the vertical direction. ) And can be stored.

The installation of the feeding and turning mechanism 19 has advantages in terms of safety and cost. When turning on a turntable installed on the boarding surface (see FIG. 12), the driver operates the vehicle on or around the turntable, so the driver misoperates the turntable, etc. There is also the possibility of an accident. In contrast, in this embodiment , a mechanism for turning the pallet 3 is installed at a place other than the boarding surface, so that the pallet 3 can be turned at a place where there is no driver, and accompanying the turning of the pallet 3 Accidents can be prevented in advance. In addition, if the pallet 3 is swung by a mechanism such as the feed and swivel mechanism 19 of the present embodiment , a special mechanism such as a turntable is not required for swiveling. Can also be reduced.

In this embodiment , the feeding and turning mechanism 19 is provided only in a part of the section 2a constituting the plane 2, and the feeding mechanism 11 is provided in the remaining sections 2a. However, all the sections 2a are provided. In this case, the feeding and turning mechanism 19 may be provided, and by doing so, the above-described turning operation can be executed in any section 2a in the plane 2, which can further improve the time efficiency. However, since the feed and swivel mechanism 19 that needs to drive each feed roller 10 individually requires a larger number of drive devices than the feed mechanism 11, the feed and swivel mechanism 19 is different from the feed and swivel mechanism 19 as in this embodiment. If the pallet 3 is installed only in a part of the sections 2a where the pallet 3 is turned and the remaining sections 2a are provided with the feed mechanism 11, the cost for construction and the like is lower.

As described above, in this embodiment , in addition to the same advantages as the above-described reference example (the output of the driving device can be relatively small, and it does not take time to switch the conveyance direction vertically and horizontally), the driving devices 12a, 12a, By adjusting the rotational speeds of 12b, 12c, and 12d, there are advantages that the pallet 3 can be transported in an oblique direction within the plane 2, and that the pallet 3 can be swiveled at a place other than the boarding surface without using a turntable.

In this way, in the above-described reference example , the object (pallet 3) cannot be moved in the oblique direction in the plane, and the pallet 3 is turned not on the plane 2 but on the entry surface 1a (see FIG. 12). On the other hand, in the present embodiment , both the oblique movement of the pallet 3 in the plane 2 and the swiveling in the plane 2 can be executed. Needless to say, the configurations described in the above embodiments may be appropriately combined so that only one of the oblique movement or turning in the plane 2 can be executed.

That is, in order to move the pallet 3 in the oblique direction in the plane 2, a certain number or more of empty sections 5 (see FIG. 12) are necessarily required in the plane 2, and the support roller is also configured of the omnidirectional wheel 20. Thus, it is necessary to have a configuration that allows movement in an oblique direction. In other words, if the storage facility 1 is configured on the assumption that the pallet 3 is moved in an oblique direction, the advantage in terms of storage efficiency and construction cost is limited to some extent instead of being able to improve time efficiency. Absent. With regard to this, when actually building a storage facility, it is necessary to individually consider whether time efficiency, storage efficiency, or construction cost is important, and appropriately select each configuration described in the above reference examples and examples . good. Moreover, in addition to the above time efficiency, storage efficiency, construction cost, etc., the configuration including the feeding and turning mechanism 19 in the lifting unit 6 and the plane 2 and enabling the pallet 3 to pivot in the lifting unit 6 and the plane 2 What is necessary is just to determine the installation number, installation position, etc. of the feeding and turning mechanism 19 in consideration of various circumstances such as the shape of the installation space of the storage facility 1.

As described above, in the present embodiment , a plane formed by arranging a plurality of compartments 2a for accommodating an object (the pallet 3 and the pallet 3 on which the vehicle 4 as a load is placed) arranged vertically and horizontally along the horizontal direction. 2 is provided with a feed mechanism 11 in which a plurality of feed rollers 10 for placing the object on the upper surface and transporting it along the plane 2 are arranged. The feed roller 10 is inclined with respect to the arrangement direction of the sections 2a on the plane 2 Since it is configured as an omnidirectional wheel 10 each having an angular rotation axis, the object can be transported on the feed roller 10 by driving the feed roller 10, and in switching the transport direction of the object vertically and horizontally, There is no need to change the direction of the feed roller 10.

In the present embodiment , at least a part of the feed mechanism 11 includes two pairs of feed rollers 10a, 10d and 10b, 10c arranged diagonally to each other, and the two pairs of feed rollers 10a, 10d. And 10b, 10c have rotating shafts that are parallel or coincident with each other, and are rotated at the same speed in the same direction for each pair by drive devices (motors) 12a, 12b provided for each pair. Since it is comprised in this way, the output required for drive device 12a, 12b can be made small, and the installation number of drive devices 12a, 12b can be made into the minimum.

In the present embodiment , at least a part of the feeding mechanism includes independent driving devices (motors) 12a, 12b, 12c, and 12d for each unit so that each of them rotates at an independent direction and speed. Since it is the feed and turning mechanism 19 in which the two pairs of the configured feed rollers 10a, 10d and 10b, 10c are arranged diagonally, the feed and turn is driven by driving of the drive devices (motors) 12a, 12b, 12c, 12d. An object placed on the mechanism 19 can be turned.

Further, in the present embodiment , since the support roller 20 that places the object on the upper surface and allows the movement of the object by rotation is provided on the plane 2, the object by the feed mechanism 11 and the feed and swivel mechanism 19 is provided. Can be carried out smoothly.

Further, in this embodiment , since at least a part of the support roller 20 is configured as the omnidirectional wheel 20, the object can be smoothly conveyed and turned in the oblique direction by the feed mechanism 11 and the feed / swivel mechanism 19. Can do.

Therefore, according to the present embodiment , the time efficiency of conveyance can be improved while reducing the cost with a simple configuration.
