Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a steady rest device for a cage, a container or the like when the cage, the container or the like is conveyed by a vertical, horizontal or inclined chain conveyor.

(Prior art) In suspension type transportation facilities such as multi-storey parking lots and containers, swinging becomes a problem when using a suspension type stand using a chain, but the following measures are available to prevent this swinging. Had been taken. (1) There is no steady rest on the chain sprocket, and the runout is prevented by keeping the chain speed low. (2) In the vertical or horizontal transportation part, the luggage or the cage is directly guided to prevent the swing.

(Problems to be solved by the invention) When transporting a cage or a container with a chain, a structurally simple steady rest device is provided to prevent buffering between conveyed goods or between conveyed goods and equipment due to shaking of conveyed goods. The purpose is to provide.

(Means for Solving the Problem) Two chains 1a and 1b vertically driven, drive sprocket wheels 2a and 2b, and driven sprocket wheel 3
In a transfer facility including a chain conveyor composed of a and 3b, an object to be transferred B has inverted U-shaped suspension supports 4a and 4b provided with a vertical height difference L on both sides thereof. Tool 4a
Link pins 5a on left and right chains 1a and 1b to support 4 and 4b
And 5b are provided with link pins 5a and 5b having a vertical phase difference L equal to the vertical height difference L of the suspension supports 4a and 4b, and sprocket wheels 2a and 2b for driving these left and right chains 1a and 1b.
The axial distance between the driven sprocket wheels 3a and 3b is also vertically shifted by a distance L.

(1st Example) It demonstrates based on a figure. A is a vertically suspended transfer facility.
1a and 1b are chains, upper drive sprocket wheel
They are endlessly wound around 2a and 2b and lower driven sprocket wheels 3a and 3b, respectively.

Referring to FIGS. 3-5, the container B has inverted U-shaped suspension supports 4a and 4b (FIG. 5) mounted above it, respectively, of the extension of the chain link pins 5a and 5b. It is hanging on each tip. As is apparent from FIG. 3, the link pins 5a and 5b are vertically out of phase by a distance L. Therefore, the sprocket wheels 2a and 2b for driving the chains 1a and 1b and the driven sprocket wheels 3a and 3b are also vertically offset from each other by a distance L.

Reference numeral 6 denotes casters attached to the bottom of the container, for example, four casters as shown in FIG. The casters 6 are guided and sent on two guides (not shown) installed on the floor.

Reference numeral 7 is a transfer device for automatically sending the container B installed at the end of the guide on the floor to the side of the transfer facility. This transfer device is composed of an endless chain. A container hooking metal fitting (not shown) is attached to the endless chain, which engages with the lower portion of the container B to transfer the container toward the transport facility A.

Reference numeral 8 denotes a movable rail, which is a recess 9 provided at the end of the floor surface as shown in FIG.
It can be lifted from a vertically downward position (two-dot chain line position) to a horizontal position (solid line position) by a cylinder 10 provided at the position and is used when the container B is hooked on the link pins 5a, 5b of the chain. Of course, the movable rail 8 is installed parallel to a guide on the floor (not shown).

Reference numeral 11 denotes a movable rail provided on another floor, which has the same structure as the movable rail 8 used when loading the container, and has a cylinder 12
Is movable between horizontal and vertical positions. The container B landed on the movable rail 11 is transferred to the floor from the transfer device 11a having the same structure as the transfer device 7.

As described above, since the left and right chains 1a and 1b and the sprocket wheels 2a and 2b and 3a and 3b are arranged vertically out of phase with each other, they travel around the sprocket in a state displaced by L. Further, since the connecting portion between the container B and the chain 1 can be rotated around the link pins 5a and 5b respectively, the container is always hung vertically not only in the vertical portion of the chain but also in the circumferential portion of the sprocket wheel. can do.

Furthermore, when the chain 1 and the container B are displaced from each other by L on the left and right, when the container shakes,
Since the left and right rotation centers are deviated, relative movement does not occur between the chain 1 and the container B, and it is possible to prevent the container from shaking.

In the above description, the container B is only hung on the chain. However, if the guide rail is attached to the vertical transfer portion of the chain 1 as necessary to prevent the chain from swaying, as a result, the container B sways. It can be prevented more completely.

(Second Embodiment) An explanation will be given based on FIGS. 7 to 10. In this embodiment, the cage C is suspended on the chains 13a and 13b without hooking the container B itself on the links of the chain. Then, the container B is carried into the cage C and conveyed. In the cage C, the suspension supporting portions 14a and 14b provided above the cage C have chains 13a and 13b, respectively.
It is hung on the link pins 15a and 15b of b, respectively.

As is apparent from FIG. 9, the link pins 15a and 15b are vertically out of phase by a distance L, as in the first embodiment. Therefore, the sprocket wheels 16a and 16b that drive the chains 13a and 13b and the driven sprocket wheels
Similarly, the axes of 17a and 17b are vertically displaced by a distance L.

In the second embodiment, if the floor rail 18 is provided at the bottom of the cage C as shown in FIG. 9, the movable rail 8 as in the first embodiment is not required and the floor rail 18 and the floor of the cage C are not required. It is sufficient if there is a transfer device 19 for connection (Figs. 7 and 9). In the example of FIG. 7, the endless chains are provided in two upper and lower stages, and container hooking fittings (not shown) are attached to these.

(Effect) In a suspension type transfer facility consisting of two-strand chains, since the container shifts the support position of the cage to the chain by the distance L in the vertical direction, 1) the container is always kept vertically due to the generation of the return moment. It can be kept and transported. 2) Since shaking can be prevented without guiding the container or cage, the equipment is simple, it can be provided at low cost, and maintenance is easy. 3) Further, since the chain sprocket part can be prevented from swinging, the chain drive speed can be increased and the receiving and paying-out time can be shortened.
