Description

[Detailed Description of the Invention] The present invention relates to an elevating device that is attached to a breeding shelf housing a large number of cages containing, for example, dogs for laboratory animals, and lifts and lowers the cages.

Conventionally, most of the lifting and unloading of cages stored in this type of breeding rack was done manually.

This is because the breeding equipment itself is placed in a room that is sterile and has other appropriate environmental protection required for animal experiments. This is because it was not possible to use it.

However, if a relatively large animal such as a dog is housed in the cage, the weight of the dog and the weight of the cage itself is usually around 60 kg (on average, the dog weighs about 40 kg and the cage weighs 20 kg). It is the rank.

), and it was an extremely difficult task to lift and unload it onto the breeding rack.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to make it possible to easily lift and lower cages without impairing the functionality of the entire breeding equipment. It is an object of the present invention to provide a lifting device as described above.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a schematic front view of a breeding device equipped with an elevating device according to the present invention. In the figure, 1 is a pedestal (breeding shelf) configured to store a large number of cages 2 in two upper and lower stages; is an elevating device that lifts and lowers the cage 2 housed in this pedestal 3.

As shown in FIGS. 2 and 3, this elevating device 3 includes a frame 4 and a top extending from the upper end of the frame 4 to the back of the breeding shelf 1 along the upper surface of the breeding shelf 1. It mainly consists of a frame 5, an arm 16 provided vertically movably within the frame 4, and a drive device 7 provided on the upper frame 5 for vertically moving the arm 6.

The frame body 4 includes a pair of channel members 8 having a U-shaped cross section,
8 are arranged parallel to each other with their open parts facing each other, and the upper and lower parts are connected by connecting members 9, 9, and the lower end thereof is connected to the guide rail 10 disposed on the pedestal 1 by guide rollers 11 and 11. The upper end of the frame 4 is supported by guide rollers 13.13 arranged to sandwich the guide beam 12 of the frame 1 so that the frame 4 is maintained in an upright state. The other end of the upper frame 5, one end of which is integrally attached to the edge, is supported by a guide rail 14 provided at the upper end of the rear surface of the pedestal 1 via guide rollers 15.15. Therefore, both the frame body 4 and the upper frame 5 can reciprocate along the left-right direction (arrow AA' direction) of the gantry 1.

The arm 6 has one end attached to a pin 16b, 16 at the top of a rectangular frame 16 having four guide rollers 16a on the upper, lower, left and right sides interposed in the channel member 8.8 of the frame body 4.
b, and the other end is rotatably supported by an auxiliary arm 17.b.
17 to the channel member 8.8.

Furthermore, when this auxiliary arm 17° 17 is not in use, it can be bent in two at its center so that the tip of the arm 6 can be tilted (rotated) downward. .

Further, a drive device 7 is disposed on the upper ladder 5.

This drive device 7 includes an electric motor 1 as shown in FIG.
8, a rotating drum 20 which is rotated by this motor 18 via a reducer 19, one end of which is wound around this drum 20, and the other end of which is connected to the arm 6 through a sheave 21.
A wire 22 fixed to the center of the upper edge of the rectangular frame 16 supporting the motor 18, and a storage battery used to supply electric power to the motor 18 and to avoid restrictions on the horizontal movement of the lifting device 3. It consists of 23.

Note that the horizontal members 6 on both sides forming a part of the arm 6
There are a plurality of rollers 24.a and 6a inside. ...... are arranged respectively, and the frame 25.25 of the mount 1
The roller 26. 27. The cage 2, which is stored in a hanging manner, can be slid horizontally and stored in the arm 6. ing.

The operation of the elevating device according to the present invention constructed as described above will be explained below.

First, when lowering the cage 2 stored in the pedestal 1, slide the frame 4 horizontally as appropriate so that the cage 2 to be lowered is in the center of the frame 4 as shown in FIG. Then, the motor 18 is driven to adjust the vertical position of the arm 6, and the roller 24 provided on the arm 6 is moved as shown in FIG.
. . . rollers 26 provided on the upper surface and the frame 25.25 of the pedestal 1.・・・・・・Align horizontally with the top surface.

Next, the cage 2 is slid toward the arm 6 (in the direction of arrow B in FIG. 2), and the cage 2 is moved from the pedestal 1 to the position below the arm 6, that is, from A to the mouth.

After completing the work of driving the cage 2 housed in the frame 1 by the arm 6 of the lifting device (suspending the cage 2 from the arm 6), the motor 18 is moved in the direction in which the wire 22 is unwound. When the motor 18 is driven, the arm 6 gradually lowers together with the cage 2, and when the cage 2 reaches the lowered position, the drive of the motor 18 is stopped.

Note that, although the cage 2 can be housed in the pedestal 1 by performing the operation in reverse to the above-mentioned operation, it will not be particularly explained here.

As detailed above, in the lifting device according to the present invention,
A pedestal in which cages are housed in multiple stages and rows, a frame that is erected so that it can run left and right on the front surface of the pedestal guided by guide rails installed on the pedestal, and a cage that runs along the frame. The system is equipped with an arm that can be slid up and down and suspends the cage, and a drive device that moves the arm up and down. It is easy to lift and lower cages, and since this lifting device can move left and right on the front of the frame, it is not only possible to lift and lower all the cages stored in the frame. This has excellent effects such as being able to easily move the cage to another storage location on the frame.

In addition, particularly in the present invention, the arm 6 has a pair of horizontal members 5a, 5a that are parallel to each other and extend horizontally. , 25 and a plurality of rollers 26...
A plurality of rollers 24 are provided for horizontally sliding the cage 2, which is suspended by its own protruding plate 27, into the arm 6. 2 can be freely slid in the horizontal direction by these rollers, and therefore the workability when raising and lowering the cage 2 and moving the cage 2 to another storage location on the frame is extremely good.

Moreover, in the present invention, when lowering the cage 2 from the pedestal 1, the lower surface of the cage 2 can be lowered directly and smoothly onto the floor, and can also be lowered onto a simple hand-operated trolley. Since the same process can be carried out when frying the cage 2, the workability is particularly good.

In addition, since a storage battery is used as the driving source, it is effective in achieving sterility and other environmental protection required for animal experiments.
