Abstract

PURPOSE:To use a floor effectively, and to enhance the efficiency of working, by providing an elevating means for shifting a cargo on a cargo loading bed riding onto a guide rail, onto a second conveyer. CONSTITUTION:When a cargo W on a pair of cargo loading beds 3 is pushed toward a second slat conveyer 2, the cargo W slides on guide rails 4a, 4b toward the conveyer 2 together with the pair of cargo loading beds 5a, 5b. As a result both cargo loading beds 5a, 5b ride on stationary guide rails 6a, 6b. When the cargo loading beds 5a, 5b are moved to a predetermined position together with the cargo W, a pair of temporarily supporting beds 7a, 7b are elevated by means of a cylinder unit to lift up the cargo W from the cargo loading bed 5a, 5b. After the emptied beds 5a, 5b are moved back, the supporting beds 7a, 7b are lowered to their original level, and therefore, the cargo W is shifted onto the second conveyer 2.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a means for transporting a load conveyed by a conveyor, for example, onto another conveyor disposed perpendicularly to the conveyor. The present invention relates to a transfer device used for transfer.

(Prior art and its problems) Conventionally, when a load is transferred between the slat conveyors as described above in a perpendicular direction, a hand truck equipped with a load support part that can be raised and lowered is used, and the load is transferred on the hand truck. It was necessary to reload the cargo once. This method of using handcarts not only requires a great deal of labor and labor for the transfer, but also has the drawback of requiring a large floor area to be secured between both conveyors to move the handcarts. was there.

Of course, one possible way to solve the above problems is to use a running fork that can be raised and lowered to move between both conveyors, but after the conveyor on the load supply side has stopped, the running fork can be moved to the lower side of the load. Since the running fork has to be moved forward, the running fork must be raised to receive the load, and then the running fork must be moved backward again, which not only lengthens the cycle time and makes it difficult to increase work efficiency. Since the running fork, which is in an extended or cantilevered state, must be raised to support the load, a large running fork with sufficient strength and a lifting drive means are required.
Equipment costs will be very high.

(Means for Solving the Problems) The present invention proposes a transfer device that can solve the above-mentioned problems. A pair of loading tables movable in the transport direction are arranged at appropriate intervals in the conveyance direction, and the pair of loading tables are arranged on both left and right sides of the end of the second conveyor, which is arranged at right angles to the first conveyor. Loading platform can be transferred to i! ! The present invention is characterized in that placing platform guide rails are arranged in parallel, and an elevating means is provided for moving the load on the loading platform that has been transferred onto the guide rail up and down and transferring it onto the second conveyor.

(Operations and Effects of the Invention) In the apparatus of the present invention configured as described above, for example, when transferring a load from the first Eva conveyor to the second conveyor, each load f2 of the first conveyor is A load is placed across the pair of A1rI loading tables, and this load LM"71
The first conveyor is stopped with the pair of guide rails connected to the guide rails on the side of the second conveyor, and the load is transferred to the load ii! ! Move it together with the table to the second conveyor side. When this loading platform transfers to the guide rail beside the second conveyor and reaches a predetermined position, the lifting means lifts the load once, returns the loading platform to the guide rail of the first conveyor, and then lowers the load. Alternatively, the load can be directly lowered together with the loading platform and unloaded onto the second conveyor.

As described above, according to the present invention, a load can be directly transferred from the first conveyor to the second conveyor at right angles by using the load platform as the load device means in the load loading section of the first conveyor. Therefore, there is no need to secure a large floor area for moving the handcart between both conveyors as in the past, and the floor surface can be used efficiently.

Moreover, once the loading section of the first conveyor stops at a predetermined position, the load can be immediately moved to the second conveyor side together with the loading platform. It is possible to significantly shorten the cycle time and increase work efficiency. or,
Since the loading platform used in the present invention only needs to be moved on the guide rail, compared to the case where a means for raising and lowering the load while supporting the load in a cantilevered state such as the running fork is used. It can be easily applied to conveyor equipment that handles heavy loads, and the work can be carried out safely.
