Technical Field

[0001] The utility model relates to the technical field related to mechanical processing, and in particular to a gravity limiting device. Background Art

[0002] After extensive searching, it was discovered that the Chinese patent publication number is CN213011815U, which discloses a material box handling AGV with a limited lifting structure, including a transport vehicle body, a composite gear, a first gear, and an electric telescopic rod. The lower end of the transport vehicle body is fixed with a universal wheel, and the transport vehicle body is fixed with a guide column, and the top of the guide column is fixed with a top plate, and the top plate is bolted to a motor. The second screw rod is provided with only a movable plate, and the movable plate is connected to the limit plate by a second spring, and the end of the movable plate is set in a slide groove, and the slide groove is opened on the loading platform. The electric telescopic rod is fixed on the loading platform, and the end of the electric telescopic rod is fixed with a baffle. The material box handling AGV with a limited lifting structure adopts the cooperation of the lifting structure and the limit structure. During the lifting process of the material box, the limit mechanism is simultaneously driven to limit and fix the material box to prevent the material box from sliding sideways. Finally, the push unloading mechanism is cooperated to realize the unloading of the box body, ensuring the stable lifting of the material box during transportation.

[0027] Example

[0028] like Figures 1 to 5 As shown,

[0029] A gravity limit device includes a lifting mechanism 1, a material frame 2, a material box 3 and a horizontal conveying mechanism 4. The lifting mechanism 1 is arranged on the left side of the horizontal conveying mechanism 4. The lifting mechanism 1 drives the material frame 2 to move in the vertical direction, and the horizontal conveying mechanism 4 drives the material box 3 to move in the left and right directions. Then the material box 3 can be transferred to the material frame 2. Several top position sensors 5 are installed on the top of the material frame 2.

[0030] Two gravity limit assemblies 6 are installed on the left and right sides of the material frame 2. The gravity limit assemblies 6 include a gravity limit body 61. The middle part of the gravity limit body 61 is rotatably installed at the bottom position of the material frame 2 through a rotating shaft 62. A counterweight block 63 is installed on the first side of the gravity limit body 61. A lower baffle 7 that is compatible with the upper counterweight block 63 is installed on the horizontal conveying mechanism 4 directly below the counterweight block 63.

[0031] A limiting tooth 64 is provided on the bottom of the gravity limiting body 61 near the counterweight block 63 , and a limiting block 8 matched with the limiting tooth 64 is installed on the bottom of the material frame 2 on the side of the limiting tooth 64 .

[0032] An upper blocking piece 65 is installed on the top of the second side of the gravity limiting body 61 .

[0033] like Figure 5 When it is working, the heavier end (i.e. the end with the counterweight 63 installed) is always vertically downward under the influence of gravity, so that the lighter end blocks the material above to achieve position limiting. Figure 3 When the device reaches the discharge position, it strikes the lower baffle 7, causing the gravity limiter body 61 to reach a horizontal position, and the material is driven out by the motor. This device has a simple structure, low cost, and easy maintenance. It cleverly uses gravity conditions to replace the traditional complex limiter.

[0034] The working principle and action sequence of this utility model:

[0035] The working principle of a gravity limit device: when the material frame 2 is fed, the lifting mechanism 1 drives the internal material frame 2 to move from top to bottom, and the material frame 2 moves to the position as shown in the figure. Figure 3 When in the position shown, the counterweight block 63 contacts the lower baffle 7 above the horizontal conveying mechanism 4. Due to the action of the lower baffle 7, the gravity limit body 61 rotates around the rotating shaft 62 to reach a horizontal position. At this time, it is in an open state. After the material box 3 is inserted, the material frame 2 moves upward driven by the lifting mechanism 1. The counterweight on one side of the counterweight block 63 has a large proportion and naturally hangs downward, thereby limiting the displacement of the material box 3.

[0036] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implying the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0037] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
