Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a movable floor device called a merry-go-round system used for loading and unloading automobiles in a multi-story warehouse.

(Prior Art) To explain a conventional example of the above-mentioned merry-go-round type multi-storey warehouse with front and back parallel arrangement, as shown in Fig. 6, a fixed floor c is arranged between the front cage _a1 and the loading/unloading entrance b. A car can be driven into the front cage A ₁ by itself using a fixed floor c, and a roller mount d is provided under the front cage A ₁ , and a lifting lift e is installed under the rear cage A ₂ . The pallet P on the rear cage _A2 is lifted up by the lifting lift e, and is slid onto the roller frame d by the conveying device f via a wire etc. to the position shown by the chain line.
The car is driven by itself onto the pallet at the chain line position, and the car is moved along with the pallet p into the back cage _a2 by the transport device f, and then the lifting lift e is moved.
A loading/unloading device is provided which lowers the pallet P onto the rear cage _A2 to carry in the automobile, and unloads the automobile in reverse order.

(Problems with the Prior Art) In the conventional loading/unloading device, a fixed floor c is provided, and when loading/unloading the rear cage _A2 , the road surface, which is a space in the front cage _A1 , and the fixed floor c are connected to each other. There is a problem that there is a difference in level between the inner and outer cages, and large-scale equipment such as a roller mount d, a lifting lift e, and a transport device f are required to carry in and out the rear cage.

(Purpose of the invention, means for solving problems) This invention is an invention to deal with the above-mentioned problems, and the proximal end is pivoted to the entrance of the car opposite to the cage into which the car is boarded. A movable floor is provided, the tip of which is movable up and down, and a floor support wheel is provided below the tip of the movable floor so as to be movable up and down via a vertical drive device, and the floor support wheel is provided. The base end of the movable floor is characterized by a high stopper at a raised position of the movable floor that supports the movable floor at a high position, and a low stopper at the lowered position of the movable floor that directly supports the lower side of the tip of the movable floor. The lower end of the movable floor is pivotably mounted so that its tip side can move up and down, and the bottom side of the tip of the movable floor is moved up and down and held in a raised position by a floor support wheel that is driven up and down, and held in a lowered position by a stopper. Accordingly, it is an object of the present invention to provide a movable floor device which enables the vertical operation of the loading/unloading floor surface, enhances the vertical operation performance, significantly improves the loading/unloading performance, and solves the above-mentioned problems.

(Example) An embodiment of the present invention is shown in Figs. 1 to 5. In Figs. 1A and 5, 1 is pivoted on the base side with a pin 2, and the tip side (left end side in the figure) is vertically connected. A movable floor is movably arranged, and a bearing 4 is provided on a base 3 below the tip of the movable floor 1, and a support arm 6 is fixed to a shaft 5 supported by the bearing 4. Floor support wheels 7a and 7b are attached to the tip of the support arm 6, and a vertical drive device 8 consisting of a power cylinder supported by a pin or the like via a bracket is swingably disposed on the base 3. The piston rod end of the vertical drive device 8 is connected to the shaft 5 via a lever 9 or the like, and the vertical drive device 8 connects the lever 9
The shaft 5 is rotated in the forward and reverse directions via the shaft 5, and the support arm 6 is swung by the forward and reverse rotation of the shaft 5, and the floor support wheels 7a and 7b are rotated.
Move up and down. Further, a high stopper 10b is provided to support the floor support wheel 7b at a high position, and a low stopper 10a is provided below the tip of the movable floor 1. It is configured to be held directly in position.

As shown in FIG. 1B, the vertical drive device 8 is equipped with a third
As shown in the figure, a plurality of support arms 6 with support wheels 7a and 7b are arranged on the shaft 5, and each support arm 7
A high stopper 10b is provided oppositely in correspondence with the movable floor 1, and a low stopper 10a is provided in parallel in correspondence with the movable floor 1.

(Function) Since the embodiment of the present invention has the above-described configuration, the vertical drive device 8 is operated as shown in FIG. 1A.
When the shaft 5 is rotated via the lever 9 and the support arm 6 is rotated to the right in the figure by the shaft 5, the lower side of the end of the movable floor 1 is supported by the floor support ring 7a at the end of the support arm 6 and rises. At the same time, since the other floor support wheel 7b is supported on the high stopper 10b, the tip of the movable floor 1 can be brought to the raised position and held by the high stopper 10b via the floor support wheel 7b. The tip of the movable floor 1 is smoothly raised by the rolling support of the floor support wheels 7a, and the tip of the movable floor 1 in the raised position is raised by the floor support wheels 7a.
Since it is supported by the high stopper 10b via b,
Sufficient supporting force is obtained even when heavy objects such as automobiles are carried in and out on the movable floor 1, and no load is applied to the vertical drive device 8 or the like.

Further, when the shaft 5 is reversely rotated by the vertical drive device 8 via the lever 9, the support arm 6 is rotated by the shaft 5.
is rotated to the left as shown in the figure, and the tip of the movable floor 1 is lowered by the floor support wheels 7a and 7b, supported on the low stopper 10a, and held at a low position as shown in FIG. Can be carried into and out of position.

To explain the case where the movable floor device is provided in the multi-story warehouse, the movable floor device 50 of the present invention is arranged as shown in FIGS. 4 and 5, and as shown in FIG. When held in the raised position,
As shown in Fig. 4, a car or the like can be carried in or out by self-propulsion directly into the front cage _A1 , and if the tip of the movable floor 1 is held at a low position as shown in Fig. 2, as shown in Fig. 5. As shown in _{FIG .}
Supplemented with movable floor 1, pit floor B ₁ for automobiles, etc.
It can be carried in and out by self-propulsion into the inner cage A ₂ through the cage A2, which greatly simplifies the loading/unloading device and significantly improves loading/unloading efficiency.

(Effects of the invention) As mentioned above, the present invention provides a movable floor whose proximal end is pivotally connected to the car exit facing the cage into which the car is loaded, and whose distal end is movable up and down. A floor support wheel 7b disposed under the tip of the movable floor 1 so as to be movable up and down via a vertical drive device 8, a high stopper 10b at a movable floor raised position that supports the floor support wheel 7b at a high position, and the aforementioned Low stopper 1 at the lowered position of the movable floor that directly supports the lower part of the tip of the movable floor 1
0a, it is possible to move the movable floor, that is, the loading and unloading floor surface, up and down, making loading and unloading more diverse.
It can be carried out quickly, and the support performance of the movable floor in the raised and lowered positions is improved.Furthermore, the loading/unloading performance is significantly improved, as it is effective in terms of structural simplification and maintenance.
