(Example)

First, a multistage lifter having a power feeding function according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a front view of a multistage lifter according to an embodiment of the present invention, FIG. 2 is a left side view of a multistage lifter according to an embodiment of the present invention, FIG. 3 is a schematic plan view seen from AA of FIG. It is a schematic bottom view seen from BB of 1.

As shown, the multi-stage lifter having a power feeding function according to an embodiment of the present invention 100 (for convenience of description, hereinafter, the "multistage lifter having a power feeding function" is referred to simply as a "multistage lifter") is a frame 103. The engine 105, the speed reducer 106, the upper sprockets 107 and 108, the lower sprocket 111, the chain 104, the conveying roller 110, the chain side feed terminal 120, etc. are provided and comprised.

The engine 105 generates a rotational force for the chain 104 to circulate as a circulator. The reducer 106 reduces the rotational speed of the engine 105 to an appropriate speed. Upper sprockets 107 and 108 are coupled to both ends of the rotation shaft 109 to transmit rotational force to the chain 104.

The chain 104 is a circular motion, which conveys the pallets conveyed from the loading conveyor to the position of the appropriate loading conveyor. The lower sprocket 111 is free to rotate to create a rotational path of the chain 104.

The controller (not shown) controls whether the engine, the feed roller 110, and the chain side feed terminal 120 operate. The support leg 101 and the moving wheels 102 are coupled to the lower end of the frame 103.

Chain-side feed terminal 120 is coupled to the outer periphery of the chain 104 by a multiple of the number of stages of the multi-stage lifter (in this embodiment, the number of stages is 5 stages, so 10 chain-side feed terminals are used). The chain-side feed terminal 120 supplies power necessary for the operation of the article 90 mounted on the pallet under the control of the controller.

Each stage of the multi-stage lifter 100 is provided with a short side feed terminal 112 and a feed roller 110 corresponding to the chain side feed terminal 120. The short side feed terminal 112 transfers the power supplied from the chain side feed terminal 120 to the feed roller 110 to supply power required for the rotation operation of the feed roller 110. The feed roller 110 receives power from the single side feed terminal 112 and transfers the pallets to the carrying conveyor.

(Operation example)

Hereinafter, an operation example of the multistage lifter 100 according to the present invention will be described.

Prior to the description of this working example, it should be noted that in the accompanying drawings, Figures 1 and 2, the second step from the top has not shown the illustration of certain components to help the understanding of the structure. It is also assumed that the article 90 brought into the multistage lifter 100 is an LCD monitor.

In the first step, the article 90 mounted on the pallet from the loading conveyor is carried into the multi-stage lifter 100.

In a second step, as the engine 106 rotates, the chain 104 circulates to raise the article 90 to the desired stage.

At this time, the article 90 carried in the lowermost stage is electrically connected to the chain-side feed terminal 120, it is possible to receive the power required for the operation test of the article 90. However, it is noted that power is not always supplied from the power supply terminal 120 on the chain side, and whether or not such power is supplied is determined by the controller.

In addition, it is noted that the power supplied from the chain-side power supply terminal 120 may be set by the controller in the amount of voltage and current required for the operation of the article 90.

In addition, when the article 90 is positioned at the desired end, the chain-side feed terminal 120 is also electrically connected to the end-side feed terminal 112.

In the third step, when the article 90 is raised to the desired stage and the test operation is completed, the control unit supplies power to the short-side feed terminal 112 electrically connected to the chain-side feed terminal 120 so that the feed roller 110 To be able to operate. Thereby, the article 90 mounted on the pallet is conveyed to a desired carry-out conveyor.

The embodiments of the present invention have been described above with reference to the accompanying drawings. However, it is to be noted that the present invention is not particularly limited only to the above-described embodiments, and that various modifications and changes can be made by those skilled in the art within the spirit and spirit of the appended claims as necessary.

As described above, according to the present invention, in the lifter including the engine, the reducer, the circulating motion part, the transfer roller part, and the conveyor, in particular, a roller driving part is installed at each end of the lifter, compared with the case of using a conventional magnetic drive part. In addition, the forward and backward time of the unit is shortened, thereby providing a step-drive type multi-stage lifter that can significantly shorten the installation time.

In addition, since at least one roller driving unit is installed at each stage, each stage of each lifter can be driven individually, thereby providing a stage-driven multistage lifter that can use or control only necessary stages.

In addition, the outer periphery of the circulating movement unit includes a circulating movement side feed terminal and each end includes a single side feed terminal supplied with power from the circulating movement side feed terminal, so that power can be continuously supplied to the article located in the lifter.

That is, in the past, when the pallet is located in the lifter part, power cannot be supplied to the pallet part. For example, the LCD module cannot be tested, but according to the present invention, power is supplied to the entire area of the lift. The power is continuously supplied while moving, so it is not necessary to provide a buffer for the activation time of the LCD module, thereby providing a step-by-step multi-stage lifter that can be stably tested in a short time.

In addition, the circulating movement part feed terminal is coupled by a multiple of the number of stages of the lifter, the lifter includes a control unit for controlling the operation of each component, it is possible to control whether or not the power supply to each stage.

As described above, according to the present invention, the chain-side feed terminal (circulation movement-side feed terminal) is coupled to the chain, and a multi-stage lifter capable of supplying power required for a test operation of the goods transported up and down in the multi-stage lifter and thus, stably inspecting the goods. Can be provided.

In addition, according to the present invention by carrying out the operation of transporting the goods to the transport conveyor through the electrically operated roller, it is possible to transport the goods irrespective of the weight of the article, the rapid progress of the goods is carried out without the movement of the transport roller Possible multistage lifters can be provided.
