Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to, for example, placing an automobile on a conveyor belt, moving the automobile in a lateral direction, stopping at a predetermined position to operate the conveyor belt, and The present invention relates to a vehicle-delivery bogie device having a function of being sent out in the front-rear direction and transferred to a parking platform.

(Prior art) Cars are loaded and transported to a parking lot at a predetermined position,
Therefore, there is known a delivery truck in which a conveyor belt is operated to send out an upper vehicle in the front-rear direction and transfer it to a parking garage. The conveyor belt of such a conventional trucking device is a toothed endless belt, and its extension is supported from below by a plurality of auxiliary rollers. However, since the endless belt is thick, the sprocket around which the endless belt is wound has a large diameter and large size, and the thick belt extends to the lower portion of the frame, so that the thickness of the entire apparatus must be increased. Since a large number of auxiliary rollers are required during the extension of the belt, the whole becomes large and heavy. Although the belt is supported by a number of auxiliary rollers, there is no support between adjacent auxiliary rollers, and thus, when the load of the vehicle is placed on the upper part, the belt is finely wavy, and the load for pulling the belt is increased. Cause.

(Problems to be Solved by the Invention) Accordingly, the present invention provides a vehicle-delivery bogie device which has a relatively simple structure, can be miniaturized, and can move an automobile smoothly with a relatively small force. The challenge is to do.

(Means for Solving the Problems) In the present invention, in order to solve the above problems, a pair of parallel conveyor belts 2 on which tires on one side of the vehicle are mounted on both sides in the short direction of the rectangular frame 1 in the longitudinal direction. The conveyor belt 2 is provided so as to be extended, and the automobile is received on the bogie device 20 or moved from the bogie device 20 to outside the bogie device 20 by moving the conveyor belt 2. Then, supporting drums 3 are erected at both ends in the longitudinal direction of the frame 1, and belt winding drums 4 are erected in parallel with the supporting drums 3, respectively, located at lower portions inside the frame than the respective supporting drums 3. The conveyor belt 2 is stretched between the belt winding drums 4 and 4 and both belt winding drums 4
A wire winding drum 6 is provided on each of the shafts, a transmission wire 7 is stretched between the two wire winding drums 6, 6, and one of the wire winding drums 6 is connected to a motor M to wind both the wire winding drums. The drums 6 and 6 and both belt winding drums 4 and 4 are rotated in the same direction in the forward and reverse directions in synchronization with each other. Further, the conveyor belt 2 is made of a synthetic resin and flat, and the frame of the conveyor belt 2 is A support plate 10 for supporting the extension over the entire length of the upper part 1 was provided, and the conveyor belt 2 was slid on the upper surface of the support plate 10 to constitute a delivery truck apparatus 20.

(Operation) In the vehicle trolley device 20 of the present invention, one of the wire winding drums 6 is rotated by the motor M, and the rotation is transmitted to the other wire winding drum via the transmission wire 7, whereby the two winding drums are rotated. The belt winding drums 4, 4 are synchronously rotated forward and backward in the same direction. Then, the flat conveyor belt 2 is taken up by any one of the belt take-up drums 4, and the automobile mounted on the upper portion is moved. When the conveyor belt 2 is wound around one of the belt winding drums 4, its diameter gradually increases, while the diameter of the other belt winding drum 4 gradually decreases. A difference in rotation speed occurs between the take-up drums 4 and 4 and thus between the wire take-up drums 6 and 6. However, when one of the belt winding drums 4 is rotating in the direction of winding the conveyor belt 2, that is, when one of the belt winding drums 4 is expanding the winding diameter, the other of the other side on the opposite side is rotated. The transmission wire 7 wound on the wire winding drum 6 is wound on the wire winding drum 6 while gradually shifting its winding position in the diameter direction of the wire winding drum 6, and at the same time, the transmission wire wound on one wire winding drum 6. 7
Is wound around the wire winding drum 6 while gradually moving its winding position in the small diameter direction, so that there is no difference in the moving speed between the conveyor belt 2 and the transmission wire 7. Therefore, excessive tension or bending does not occur on the conveyor belt 2 or the transmission wire 7. Conveyor belt 2
The lower surface is supported by the support plate 10 during its extension, and the vehicle travels smoothly with frictional contact with the upper surface of the support plate 10 with the vehicle mounted thereon.

(Embodiment) FIGS. 1 and 2 show an embodiment of the present invention. FIG. 1 is a plan view of a vehicle-delivery bogie device, FIG. 2 is a front view of the same, and FIG. 3 is a front view of a wire winding drum.

The vehicle-delivery bogie device 20 of this embodiment can be moved laterally along the rail by the wheels 11, but the description of the moving mechanism is omitted. On both sides of the rectangular frame 1 in the short direction, a pair of parallel conveyor belts 2, 2 on which tires of an automobile are mounted are provided so as to extend in the longitudinal direction. The conveyor belt 2 is made of a synthetic resin and is flat. The conveyor belt 2 is wound around support drums 3, which are installed in both ends of the frame 1 in the longitudinal direction in the short direction.
The belt winding drum extends at both ends
Locked to 4,4. The belt winding drum 4 is provided on both sides of the lower portion of the frame 1 in the longitudinal direction in a short direction. A wire winding drum 6 is provided on a shaft 4a of both belt winding drums 4, and a transmission wire 7 is stretched between these wire winding drums 6 so as to be wound. The wire winding drum 6 has a conical shape whose diameter gradually decreases toward the opposite end, and has a helical shape so as to shift the winding diameter in the larger diameter direction as the wire 7 is wound. Guide grooves 6a are formed. An intermediate portion of the transmission wire 7 is connected to a tension adjusting device 8.
To maintain a predetermined tension at all times. One shaft 4a is connected to a motor M via a transmission belt 9, so that the forward and reverse rotation of the motor M causes both belt winding drums 4 and 4 to rotate forward and backward in synchronization with each other in the same direction. Has become.

A support plate 10 is stretched on the frame 1 so as to contact the lower surface of the conveyor belt 2. Therefore, the conveyor belt 2 slides on the upper surface of the support plate 10 with the automobile mounted thereon.

In the vehicle-delivery bogie device 20 of this embodiment, for example, a car is received on a flat conveyor belt 2 from a parking stand (not shown), and the conveyor belt 2 is wound around any of the belt winding drums 4, and is placed on the upper portion thereof. The mounted car is moved back and forth. Belt winding drum 4
Is rotated by a motor M. That is, one wire winding drum 6 is rotated by the motor M via the transmission belt 9, and this rotation is transmitted to the other wire winding drum 6 via the transmission wire 7. , 4 are synchronously rotated forward and backward in the same direction. When the conveyor belt 2 is wound on one of the belt winding drums 4, its diameter gradually increases, while the diameter of the other belt winding drum 4 gradually decreases. A difference in rotation speed occurs between the take-up drums 4,4. However, during this time, the other wire winding drum 6 winds the wire 7 while gradually shifting its winding position in the large diameter direction, and the one wire winding drum 6 shifts the winding position in the small diameter direction gradually. 7
In the end, the conveyor belt 2 and the wire 7 are synchronized with each other, so that excessive tension and bending do not occur.
The contraction rate of the diameter of the wire winding drum 6 is set to a predetermined rate in accordance with the rate of increase and decrease of the winding diameter of the belt winding drum 4. The conveyor belt 2 is always in an appropriate tension state. The lower surface of the conveyor belt 2 is supported by the support plate 10 during its extension, and the conveyor belt 2 always advances while smoothly and frictionally contacting the upper surface of the support plate 10. Then, the vehicle on the conveyor belt 2 is lowered to a predetermined place. Further, in the vehicle delivery truck device 20 of the embodiment, since the conveyor belt 2 is thin and has good flexibility, the supporting drum 3 and the belt winding drum 4 need only be small in diameter.
Therefore, the thickness of the device is as small as possible.

(Effects of the Invention) As described above, in the present invention, a pair of parallel conveyor belts 2 on which the front and rear tires of one side of the vehicle are respectively mounted are provided on both sides in the short direction of the rectangular frame 1 so as to extend in the longitudinal direction. By moving the conveyor belt 2, the automobile is received on the bogie device 20 or the bogie device 20 is received.
It was moved out of the bogie device 20 from above. Then, supporting drums 3 are erected at both ends in the longitudinal direction of the frame 1, and belt winding drums 4 are erected in parallel with the supporting drums 3, respectively, located at lower portions inside the frame than the respective supporting drums 3. The conveyor belt 2 is stretched between the belt winding drums 4, 4, and the wire winding drums 6 are provided coaxially with the belt winding drums 4, respectively. 7 and one of the wire winding drums 6 is connected to a motor M so that both wire winding drums 6, 6 and both belt winding drums 4, 4 are rotated in the same direction in the forward and reverse directions in synchronization with each other. Further, the conveyor belt 2 is made of a synthetic resin and flat, and an extension of the conveyor belt 2 on the frame 1 has a support plate 10 for supporting the conveyor belt 2 over its entire length.
And the conveyor belt 2 is slid over the upper surface of the vehicle, so that the vehicle arrangement device 20 is relatively simple in structure and can be reduced in size, and the vehicle can be moved smoothly with relatively small force. It is possible to provide a vehicle trolley device capable of causing the vehicle to move.
