Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a transfer device using a conveyor, and more specifically, a transfer device suitable for moving an automobile between an elevator for moving an automobile up and down and a rack portion for storing the automobile in a multi-storey parking lot. Regarding

[0002]

[Prior Art]

 As a parking lot for storing cars three-dimensionally, a type has been proposed in which multiple racks are installed on the upper and lower floors facing the lift zone of an elevator that moves the cars up and down, and the cars are stored three-dimensionally in each rack. ing.

In such a multi-storey parking lot, a transfer device for transferring vehicles to each other is required between the elevator and each rack section.

Conventionally, as the above-mentioned transfer device, for example, a structure is used in which a pallet for mounting an automobile is used and the pallets are transferred to each other by a feed mechanism provided in an elevator and a rack part.

[0005]

[Problems to be solved by the device]

 However, the transfer device for laterally feeding the pallets has a problem that the structure for horizontally feeding the pallets becomes complicated, and moreover, an equal number of pallets must be prepared in the rack section, which increases the equipment cost.

A belt conveyor may be used as a means for reducing the cost by simplifying the structure of the transfer device. In this case, in order to avoid interference when the elevator is moved up and down, a belt conveyor on the elevator is used. A sufficient space must be secured between the opposite ends of the belt conveyor of the rack and the rack conveyor, which causes a problem that the transfer of the car between the belt conveyors is hindered, which is not solved. As far as possible, it is difficult to use a belt conveyor.

Therefore, the present invention eliminates the gap between the belt conveyors when transferring the vehicle between the belt conveyors, and enables the smooth transfer of the vehicle between the belt conveyors without any trouble. It is an object to provide a transfer device using a conveyor that can be adopted.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a plurality of endless belts arranged side by side to form a conveyor having an upper surface as a conveyor surface, and the pair of conveyors described above are connected in series in a conveyor direction. Are arranged so as to face each other, and at least one of both carriers is movable back and forth with respect to the partner carrier, and the ends of the endless belts are arranged at predetermined intervals at the opposite ends of the carriers. The configuration is such that the two parts are projected toward each other, and the protruding parts are provided on both carriers so that they will fit each other when the two carriers approach each other.

[0009]

[Action]

 In order to transfer this transported object onto the other transported body while the pair of transported bodies are separated from each other and the transported object is placed on the one transported body, one of the transportation bodies is directed to the other transportation body. Move forward to approach.

Since the end portions of the endless belts alternately project at the facing end portions of the two conveying bodies, when the facing end portions approach each other, the projecting end portions of the endless belts are alternately fitted to each other, and the two conveying body portions are in contact with each other. The gaps generated between the end portions of the sheet are filled, and therefore the object to be transported is smoothly transferred from one carrier to the other carrier by driving both endless belts.

Further, after the transfer, the one carrier returns to the retracted position, and when the one carrier moves up and down, the occurrence of interference between both carriers is eliminated.
