CONSTITUTION:In the state where the right and left transfer wagons 6a and 6b in pairs which can freely shift in reciprocation are set at a waiting position, if a transported article W supported onto a slat conveyor 1 reaches the opposed position between an engaged pin and a clamp hook, the transfer wagon 6a is connected with the conveyor 1, and the wagon 6a traction-shifts, and the wagon 6b synchronously shifts. Then, the tranported-article lifting-up apparatus of the wagons 6a and 6b are operated, and the transported-article W on the conveyor 1 is lifted-up, and after the wagons 6a and 6b are separated from the conveyor 1, the wagons 6a and 6b are synchronously traveled at a prescribed speed to the transport means 3 side. After the transported-artiole W on the wagons 6a and 6b reaches a prescribed position directly over an elevation guide rail 4c, said wagons 6a and 6b are stopped, and lowered to a descent limit by the lifting-up means, and then transferred onto a wagon 5, and thus the device can be made small-sized by removing a gate-shaped crane.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a transfer device that lifts an object from both left and right sides and transfers it onto a next-stage object supporting and conveying means, for example, a transport vehicle.

(Prior art and its problems) The conventional transfer device used as described above lifts the conveyed object on the conveyor above it, transfers it to the next conveyance means, and then lifts it down. It was common to use gate-shaped lanes. Since such gate-shaped lanes are generally very large and carry heavy objects, this method is used to make the lanes run in synchronization with the conveyor when lifting objects from the conveyor. It is impossible to connect a lane and a conveyor and have the conveyor tow the lane, so generally the driving means of the lane is electrically controlled so that the lane travels in synchronization with the conveyor. A method was taken to do so.

Therefore, a control means for synchronized running is required, and in conjunction with the use of gate-shaped lanes, a device (means for solving the problem) The present invention solves the above-mentioned conventional problems. The purpose is to provide a transfer device that can solve the problem, and its feature is that the next stage is installed adjacent to the end of the conveyor to support and transport the transported object from both left and right sides of the end of the conveyor that supports and transports the transported object. A movable trolley capable of reciprocating independently in parallel with the conveyor is installed on both left and right sides of the means, and an interlocking means for synchronously interlocking the two movable trolleys in a mutually facing state; A driving means for reciprocating both movable carts is provided, and at least one of the movable carts is provided with a retaining means that can be freely engaged with and disengaged from the engaged portion provided on the conveyor, and furthermore, both moving carts are provided with a driving means for reciprocating the movable carts. The present invention is characterized in that conveyed object lifting means are respectively provided which are capable of moving laterally into and out of the conveyor and are capable of being raised and lowered.

(Function) In the above transfer device, when the conveyed object on the conveyor reaches a predetermined position between the pair of left and right movable carts waiting at the starting end position of the moving path, the engaging means is activated. The movable trolley is pulled and moved by the conveyor by being activated and engaged with the engaged portion on the conveyor side, and the conveyor and the movable trolley provided with the engaging means are connected. At this time, the other movable carriage, which is not provided with the engaging means, moves in conjunction with the movable carriage which is pulled as described above by the interlocking means, while maintaining a state of facing each other.

In such a state, when the conveyed object on the conveyor is lifted from both left and right sides by the conveyed object lifting means on both movable carts, the engagement between the engaging means and the engaged portion on the conveyor side is released, and the above-mentioned The driving means moves the pair of left and right movable carts in conjunction with each other at a desired speed, and transports the object to a predetermined position above the object supporting and transporting means of the next stage. Thereafter, by lowering the transported object lifted by the transported object lifting means to a predetermined position of the transported object supporting and conveying means, a series of transported objects are moved from the conveyor to the next stage of the transported object supporting and conveying means. Transfer work is completed.
