Abstract

PURPOSE:To process a plurality of articles to be conveyed with a single lifting device by providing a plurality of sets of article receiver tables on the lifting device serving to lift the article, and further providing a stopper for stopping the article between the article receiver tables. CONSTITUTION:Upon warehousing for example an article 4 to be conveyed,the article 4 is first conveyed by a chain conveyor 1 and stopped by a stopper 2. In succession, detected the article 2 being adapted to make close contact with the stopper 2 and stopped, a lifting device 3 is operated to lift only a stopper 35 to be located upwardly of a plane of conveyance. A second article 4 to be conveyed is stopped by the stopper 35. Thereafter, the lifting device 3 is further elevated to completely lift the article 4 from the plane of conveyance. Then, a fork 5 of a stacker crane is operated in the above situation to transfer the article 4 on the same crane for storing it on a warehouse shelf.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a transfer station suitable for use as a loading/unloading station in an automated warehouse.

[Background of the invention]

At the loading/unloading station of an automated warehouse, there is a stopper that stops the transported items on a conveyor line or other transport line, and a stopper that stops the transported items so that the stopped transported items can be scooped up by a stacker crane with a fork. Lifting equipment is used to lift. In this case, if a plurality of objects are to be handled at the same time, lift devices are generally installed for the same number of objects to be handled at the same time.

Incidentally, as a prior art, the one disclosed in Japanese Patent Application Laid-open No. 199720/1983 is known. This technology uses a separate mechanism to lift the objects conveyed on the conveyor line.
t. However, it is difficult to scoop up the transported items placed on the lift device flc with the fork of a stacker crane or the like. It is possible to pick up items by inserting a fork into the space on the pallet, but in that case the height of the pallet must be set so that the fork can be inserted, and this does not match the height of the shelf. This is undesirable because it limits the amount of cargo that can be stored.

[Purpose of the invention]

An object of the present invention is to provide a transport station that can handle a plurality of objects with a simple configuration.

[Summary of the invention]

The present invention has a simple configuration so that a single lift device can handle multiple objects.The lift device at the transfer station has multiple receiving platforms for objects in the transfer direction. It is characterized in that it is equipped with a stopper for stopping the conveyed object between the plurality of sets of receiving racks.

[Embodiments of the invention]

Hereinafter, the present invention will be explained in detail based on specific examples.

FIG. 1 is a diagram showing an embodiment of the present invention, and FIGS. 2 to 5 are diagrams showing the warehousing operation of the embodiment. In FIG. 1, 1 is a roller conveyor, a chain conveyor, etc. A chain conveyor is shown here. Reference numeral 2 denotes a stopper, which has the function of stopping the object 4 being conveyed on the line. 3 is a lift device, which has a function of lifting objects to be transported. Reference numeral 31 indicates a glue jack portion of the lift device. 32 is a support plate, 33 and 34
Reference numeral 35 denotes a loading platform provided on the support plate, and a stopper 35 provided between these loading platforms. The cargo trays 33, 34 and the stopper 35 are installed in the transport direction as shown. 36 is a worm gear that moves the stopper 35 up and down.

Now, at the Yogyo conveyance station shown in Figure 1,
The case of storing transported items will be explained below using FIGS. 2 to 5. The conveyed object 4 conveyed by the chain conveyor 1# is moved to a stopper 21 provided with a stop position WLc.
It is stopped by C.

In this state, the stopper 35 of the lift device 3 and the loading platform 33, 34 are held below the transport level of the transport line. Figure 2 shows this situation. Stotz f
2, when it is detected that the transported object 4 has stopped (detected by a limit switch, etc. not shown), the lift device 3 is activated and raised so that only the stopper 35 is positioned above the transport level. . This state is the state shown in FIG. In this state, when the second conveyed object 4 is conveyed, the stopper 3 is moved as shown in FIG.
It is stopped by 5. After the second transport stop, change the lift bag if3? The conveyed object 4 is completely lifted from the conveying line as shown in FIG. In this lifted state, operate the fork 5 of the stacker crane to transfer the transported object 4 onto the stacker crane,
Store it in the warehouse. In the case of unloading, it is sufficient to operate in the exact opposite manner to the above-mentioned operation. That is, the fork 5C of the stacker crane lifts up the transported goods 4 onto the receiving platform of the lift device 3, which has been lifted up as shown in FIG. Place it. Next, as shown in FIG. 4, lift 1. ! tfi down 111
and move the chain conveyor l in the unloading direction. As a result, the P-1th object 4 is transported as shown in FIG. By lowering the lift device 3 after a certain period of time, the next conveyed object 4 is also conveyed.

It should be noted that the conveyed goods 4 are transported to both loading trays 33.3.
4) In the case of a large item that crosses over the cargo area, the position of the stopper 35 can be lowered by the worm gear 36 (to the same level as or below the level of the receiving platforms 33 and 34). Can you drive a car?

〔Effect of the invention〕

As described above in detail, according to the present invention, a plurality of objects to be transported can be handled by one lift bag Ttc, and a simple configuration can be achieved.

[Brief explanation of drawings]

FIG. 1 is a diagram showing one embodiment of the present invention, and FIGS. 2 to 5 are diagrams for explaining the operation of the embodiment shown in FIG.
