Description

[Detailed description of the invention] This invention is a device that transports relatively heavy items in a suspended state. This invention relates to a device for easily and reliably lifting and lowering.

By the way, when a relatively heavy item, such as an edible carcass, is suspended from a transport rail installed in the air near the ceiling and transported along the rail, at the end of the rail, It is often necessary to raise and lower such items to and from a platform or floor below this point. That is, in the case of the carcass in the above example, the work of hooking the carcass to a trolley lift suspended from the transport rail or removing it from the hook is often performed. Since the weight of such articles is large, lifting and lowering such articles requires a great deal of labor and is inefficient if carried out manually. Therefore, in the past, a hoist or a chain block was used to hoist the trolley lift on which the above-mentioned articles were hung in advance to the height of the conveyor rail, and then transfer it onto the rail, or alternatively, the article was lifted from the rail. The entire trolley is being lowered down. However, in this case, even if the labor could be reduced, careful attention was required to transfer the trolley pack to and from the transport rail, which was unexpectedly time-consuming, and the transfer could fail. There is also a high risk of objects falling unexpectedly.

The present invention addresses the above-mentioned conventional problems and makes it easier and more reliable to lift and lower articles to and from the transport rail. The groove wheel provided at the upper end of the trolley lift truck is connected to the end of the trolley, and corresponds to the movable pulley for the wire, etc., and when the groove wheel is lifted up to the height of the conveyor rail by the wire, etc.,
This allows the groove wheel to move extremely smoothly between the wire, etc. and the rail.
Hereinafter, an embodiment shown in the drawings will be described in detail.

In the figure, reference numeral 1 indicates a transport rail that is suspended in the air by hangers 3 along the ceiling 2 of a warehouse or other place, and 4 is a trolley lift that can be freely moved along the rail while hanging from the rail. . The above-mentioned transport rail 1 has a narrow rail surface 1a along the upper surface, and the trolley leaf 4 has a frame 4a.
The upper end is rotatably provided with a groove wheel 4b that can ride on the rail surface 1a and roll freely, and the lower end is provided with a hook 4c on which the article 5 to be suspended and conveyed can be hung. We are prepared. 6 is a winding wire (or chain),
One end 6a of this is connected to the end of the transport rail 1 so as to extend the rail surface 1a, and is connected using a wire clip 7 or the like. This wire 6 can be raised and lowered by suspending the groove wheel 4b like a movable pulley, and the other end portion 6b of the wire is wound around a hoisting drum 8 installed near the ceiling 2. ing. The winding drum 8 is rotated in either the winding direction or the unwinding direction by either forward or reverse rotation selectively transmitted from an appropriate power source to the drum shaft 9 at any time. 10 is trolleyfuku 4
A limit switch that regulates the upper limit of the lifting height by the hoisting drum 8, and is provided near the drum so that the trolley lift is at a predetermined height, that is, the groove wheel 4b is at the same height or slightly higher than the rail surface 1a. When the frame body 4a is lifted up to a height of , it is pushed by the upper end of the frame body 4a, and the transmission of rotation to the drum shaft 9 is stopped. In the illustrated example, the hoisting drum 8 is installed near the ceiling 2 above the end of the transport rail 1, but a fixed pulley is installed at that position and the drum itself is installed elsewhere. Alternatively, the limit switch 10 in this case would be provided near the fixed pulley. In addition, the hoisting drum 8 is cone-shaped in the illustrated example, and the length of the wire 6 is calculated in advance so that the end of the wire will be on the extension line of the conveyor rail surface 1a when the trolley lift 4 is hoisted. Care has been taken to ensure correct alignment, but even if a slight deviation occurs between the wire end and the rail surface extension line, this will not impede the transfer of the groove sheave 4b.

In the above-described configuration, the hook 4c of the trolley lift 4 is removed from the transport rail 1.
, hooking the article 5 to be suspended and conveyed,
After the groove wheel 4b is suspended like a movable pulley from the wire 6 let out from the hoisting drum 8, when the hoisting drum 8 is rotated in the winding direction, the trolley leaf 4 is moved as shown in FIG. When it is lifted straight upward from the position shown by the solid line and reaches the end of the conveyor rail 1, and the groove wheel 4b reaches a height that is the same level or slightly higher than the rail surface 1a, it is stopped by the action of the limit switch 10. do. However, the end of the wire 6 at this time is on a line extending the rail surface 1a of the transport rail 1. Therefore, when a slight force is applied to the trolley hook 4 in the direction toward the conveyor rail 1 by lightly pushing the article 5 to the left in FIG. It rolls very naturally from the edge of the rail onto the rail surface 1a. Therefore, trolley stock 4
is from the hoisting wire 6 onto the conveyor rail 1,
The transfer is extremely smooth, and the article 5 can be suspended below and conveyed along the rail.

Further, when the hoisting wire 6 is in the hoisted state as described above, there is a trolley lift 4 suspending the article 5 from the conveyor rail 1 as shown by the chain line on the left side of FIG. Move it to the end of the rail and move it further forward. Then, the groove wheel 4b of this trolley stock 4 is placed on the rail surface 1.
A to the end of the wire 6 on the extension line of the plane very naturally, and the trolley leaf 4 is very smoothly transferred from the top of the conveyor rail 1 to the wire 6. Therefore, when the hoisting drum 8 is rotated in the unwinding direction, the trolley hook 4 is lowered by the wire 6 using the groove wheel 4b as a movable pulley, and the article hooked on the hook 4c is lowered. Become.

As described above, the present invention connects one end of a hoisting wire or chain to the end of a transport rail for suspending and moving a trolley lift so as to extend the rail surface, and connects the other end of the wire, etc. It is wrapped around a hoisting drum, and the trolley wheel on the trolley leaf roll that rolls on the rail surface is made to correspond like a movable pulley, so that the trolley leaf can be raised and lowered using the wire, etc. According to the present invention, in hanging conveyance equipment for relatively large items,
The trolley hook can be easily raised and lowered between the end of the conveyor rail and the platform or floor below it while the above-mentioned article is still hooked to the hook, and the groove wheel is flush with the surface of the conveyor rail. While being hoisted to a height or close to this height, it is placed on the conveyor rail from the wire of the trolley lift, etc.
Alternatively, the transfer in the opposite direction can be performed extremely smoothly, and therefore, the work of raising and lowering articles suspended and conveyed from a conveyor rail to and from the rail can be carried out easily, reliably, and safely. You can expect it.
