| 摘要 | The present invention relates to an engage-disengage device for a cargo-transfer device such as a fork in a palletless mechanical cargo handling system of the load-replacing type. The cargo is transferred between a cargo transfer device which is available for handling and transporting cargo in a specified unit or for storing cargo on a rack and the like, and a stationary mechanism installed on the floor of a truck or container or on a cargohandling platform. The device is equipped with a plurality of slots to receive a plurality of tines in the fork, characterized by making it possible to load or unload said fork automatically without unpacking and with no manpower needed. A fixed frame is provided which is equiped with plural rows of cargo transport mechanisms arranged in parallel and spaced apart. A vertically-movable frame is equipped with a plurality of vertically-movable transport mechanisms for the cargo-transfer device arranged between said cargo-transport mechanisms. The cargo-transport mechanism is provided with a conveyor which carries cargo. The top surface of the transport mechanism for the cargo-transfer device is located higher than the top surface of said fixed frame. By displacing the transport mechanism for the cargo-transfer device downward along the fixed frame, a piece of cargo on said cargo-transfer means can be transferred to the fixed frame. The cargo-transfer device is displaced further down and tilted such that it moves by itself. The cargo transferred to the fixed frame is forwarded on a conveyer belt to its destination. The system may be operated in a reverse direction to load said devices. | ||||||
| 权利要求 | 1. An engage-disengage device for a cargo-transfer means havIng a plurality of parallel tines in a mechanical cargo handling system of the load-replacing type characterized in that the device comprises: a. a fixed frame including rows of cargo-transport means arranged in parallel and spaced apart at a distance greater than the width of said tines with a transport mechanism that can carry cargo thereon; b. a vertically-movable frame including transport means for the cargo-transfer means comprising at lease two arms extending parallel to the rows of said cargo transport means that can move vertically between the rows of said cargo-transport means said arms engaging at least two of said tines wherein said transport means for the cargo-transfer means, and said vertically movable frame is provided with a vertical displacement means for moving said transport means for the cargo-transfer means in the vertical space between said cargotransport means. 2. The engage-disengage device for a cargo-transfer means of claim 1, wherein said cargo-transport means of the fixed frame consists of an endless conveyor belt having a horizontal part in said conveyor belt being slightly higher than the top surface of the fixed frame, and includes more than one free roller to keep in contact with the under side of the upper part of the conveyor belt. 3. The engage-disengage device for cargo-transfer means of claim 1, wherein said vertical displacement means comprises crossed arms, symetrically positioned around a center shaft, one pair of ends of said arms being coupled respectively at specified positions to one end of the vertically-movable frame and to the bottom of the vertical part of the fixed frame, and the other pair of ends of said arms being movable along guide means, and ram means for vertically moving said center shaft. 4. An engage-disengage device for a cargo-transfer means of claim 3, wherein said transport means for cargo-transfer means is equipped with a stopper means which arrests the downward displacement of said transport means by hitting the bottom of the other end of said vertically-movable frame when it has been displaced downward a predetermined amount whereby said transport mechanism can be tilted. 5. An engage-disengage device for a cargo-transfer means of claim 3, wherein the upper one of the other ends of said crossed arms can be moved along a guide means which is inclined upward at an angle. |
