Description

Technical Field

[0001] This utility model relates to the field of material transfer technology, specifically to a rotary buffer device for transfer containers. Background Technology

[0002] Currently, there are many transfer and transportation processes on industrial production lines. Some of these transfers involve certain drops in elevation, especially for fragile items and products that cannot withstand friction, which require the use of transfer containers. This can lead to damage or appearance defects due to friction and compression. Once a product is damaged, the entire transfer container containing the key product will be affected, resulting in a decrease in product qualification rate and an increase in production costs. Therefore, this application is submitted. Utility Model Content

[0003] The purpose of this utility model is to provide a rotary buffer device for transfer containers. By setting a rotating component, the transfer container rotates synchronously with the placement platform. During the material transfer process, the height difference between the bottom of the transfer container and the product outlet is reduced in sequence, so that the material maintains its integrity when entering the transfer container, thus solving the problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] A rotary buffer device for a transfer container includes a device body, the device body including a first symmetrical side plate and a second side plate located between the first side plates, the top of the first side plate is provided with a rotating assembly for supporting the transfer container, and the second side plate is provided with a photoelectric sensor for monitoring the material height inside the transfer container, the transfer container rotating synchronously inside the device body with the rotating assembly.

[0006] Furthermore, the rotating assembly includes bearings symmetrically located at the top of one of the side plates, a rotating rod is provided inside the bearing, and a main connecting rod is provided at the end of the rotating rod away from the bearing and fixedly connected to the placement platform, and the transfer container is located above the placement platform.

[0007] Furthermore, secondary connecting rods are provided between the main connecting rods.

[0008] Furthermore, one of the rotating rods has a bearing through its end and is equipped with a bevel gear one, which meshes with a bevel gear two and is connected to the output end of the geared motor.

[0009] Furthermore, both bevel gear one and bevel gear two are located inside the fixed box.

[0010] Furthermore, the rotation angle of the placement platform is 0–90° in the forward direction or 0–90° in the reverse direction.

[0011] Furthermore, an upper limit photoelectric switch is provided at the top of the second side plate, and a lower limit photoelectric switch is provided at the bottom of the second side plate. When the placement platform is parallel to the bottom plate of the device body, the lower limit photoelectric switch is flush with the bottom of the placement platform.

[0012] Furthermore, the upper limit photoelectric switch and the lower limit photoelectric switch are electrically connected to the controller of the geared motor.

[0013] Furthermore, a buffer pad is provided on the outer periphery of the lower limit photoelectric switch.

[0014] Furthermore, omnidirectional wheels and directional wheels are symmetrically arranged at the bottom of the device body, with the directional wheels located below the second side plate and the omnidirectional wheels located away from the second side plate.

[0015] The beneficial effects of this utility model are:

[0016] In this invention, a rotating component is installed within the device body. The transfer container is positioned above the placement platform and rotates under the forward and reverse driving action of a geared motor. This ensures that the feed inlet of the transfer container is at its highest point for feeding. When a photoelectric sensor detects material inside the transfer container, it drives the geared motor to operate, causing the output end of the geared motor to rotate slowly and uniformly in the forward direction. This keeps the feed inlet of the transfer container at the same height as the discharge outlet of the conveying device until the placement platform stops rotating at the lower limit photoelectric switch. This ensures that the material transfer is always at the same height as the discharge outlet, maintaining the integrity of the material during the transfer process, preventing collisions between products, providing a buffer for the rotation of the placement platform, and improving the product qualification rate.

[0025] Example 1

[0026] Embodiment 1 of this utility model is a rotary buffer device for a transfer container, including a device body 1. The device body 1 includes a symmetrical side plate 10 and a side plate 2 11 located between the side plates 10. A rotary assembly 2 for carrying the transfer container is provided on the top of the side plate 10. The side plate 2 11 is provided with a photoelectric sensor 3 for monitoring the material height inside the transfer container. The transfer container rotates synchronously inside the device body 1 with the rotary assembly 2.

[0027] Reference Figures 1-3The technical concept of this application is to set a rotating component 2 inside the device body 1. In the initial state, the transfer container and the rotating component 2 are in a vertical state, and the surface formed by the feed port of the transfer container is on the same vertical axis as the bottom of the device body 1. When it is necessary to transfer materials to the transfer container, the external controller drives the rotating component 2 and the transfer container to rotate synchronously, so that the surface formed by the feed port of the transfer container is almost parallel to the bottom of the device body 1. In this state, the material transfer to the inside of the transfer container is started. The photoelectric sensor 3 set on the side plate 2 11 will detect the change in the height of the material inside the transfer container, thereby driving the rotating component 2 to rotate downward, so that the discharge port and the feed port always maintain a consistent height difference, preventing the material inside the transfer container from rubbing against each other due to excessive height difference and causing damage.

[0028] In some preferred embodiments, the rotating assembly 2 includes bearings 20 symmetrically located on the top of the side plate 10, a rotating rod 21 is provided inside the bearing 20, and a main connecting rod 22 is provided at the end of the rotating rod 21 away from the bearing 20 and fixedly connected to the placement platform 23, and the transfer container is located above the placement platform 23.

[0029] Specifically, the transfer container rotates synchronously with the rotating assembly 2 mainly by rotating the rod 21 within the bearing 20 under the control of an external drive device, and drives the placement platform 23 to rotate through the main connecting rod 22, causing the height of the placement platform 23 and the transfer container to change, thereby facilitating the transfer of materials within the transfer container.

[0030] It should be noted that the transfer container is securely positioned above the placement platform 23 and can be fixed by welding or other methods, which are existing technologies, to ensure that the transfer container is fixed and rotates with the rotating component 2.

[0031] In some preferred embodiments, secondary connecting rods 220 are provided between the main connecting rods 22. The secondary connecting rods 220 connect and reinforce the two main connecting rods 22, allowing the rotating rod on the right to quickly transmit rotational force to the rotating rod on the right, thus causing the two rotating rods to rotate synchronously. The number of secondary connecting rods 220 can be set according to actual conditions, mainly to ensure the stability between the two main connecting rods 22.

[0032] To ensure the stability of the placement platform 23 in rotating the transfer container, one end of a rotating rod 21 passes through a bearing 20 and is equipped with a bevel gear 26. The bevel gear 26 meshes with a bevel gear 27, and the bevel gear 27 is connected to the output end of the reduction motor 24. Both the bevel gear 26 and the bevel gear 27 are located inside the fixed box 25.

[0033] Reference Figure 4A bevel gear 26 is provided at the end of the right rotating rod 21, and it meshes with the bevel gear 27 at the output end of the geared motor 24, so that the geared motor 24 drives the rotating rod 21 to rotate at a constant speed through the bevel gear 27 and the bevel gear 26.

[0034] When the photoelectric sensor 3 detects that the material in the transfer container has accumulated to the same level as the photoelectric sensor 3, the photoelectric sensor 3 will drive the external controller to start the geared motor 24, so that the rotating rod 21 will rotate slowly, eventually lowering the height between the transfer container and the placement platform 23; until the photoelectric sensor 3 no longer detects the material in the transfer container, it will drive the external controller to turn off the geared motor 24, thus completing the material transfer.

[0035] It should be noted that the speed at the output of the geared motor 24 should be set according to the actual situation.

[0036] Meanwhile, the fixed box 25 helps to protect the first bevel gear 26 and the second bevel gear 27, preventing dust accumulation from affecting the transmission effect.

[0037] In some preferred embodiments, the rotation angle of the placement platform 23 is 0–90° in the forward direction or 0–90° in the reverse direction. That is, the rotation angle of the rotating rod 21 is also 0–90° in the forward direction or 0–90° in the reverse direction, thereby allowing the transfer container to change its height within the rotation angle range of 0–90° in both directions. When the rotation angle of the rotating rod 21 is at its maximum value, the lowest point of the discharge port of the transfer container is always lower than the surface of the side plate 11, which is beneficial for the transfer and transportation of materials.

[0038] It should be noted that the geared motor 24 in this device is a servo motor, and the rotation angle of the output end can be set in the internal driver to be 0 to 90° in the forward direction and 0 to 90° in the reverse direction, so that the bevel gear 27 drives the rotating rod 21 to rotate in the forward and reverse directions via the bevel gear 26.

[0039] Example 2

[0040] This embodiment 2 is implemented based on embodiment 1. An upper limit photoelectric switch 4 is provided on the top of the second side plate 11, and a lower limit photoelectric switch 5 is provided on the bottom of the second side plate 11. When the placement platform 23 is parallel to the bottom plate of the device body 1, the lower limit photoelectric switch 5 is flush with the bottom of the placement platform 23. The upper limit photoelectric switch 4 and the lower limit photoelectric switch 5 are electrically connected to the controller of the reduction motor 24.

[0041] Specifically, the device body 1 is equipped with an upper limit photoelectric switch 4 and a lower limit photoelectric switch 5. When the placement platform 23 drives the transfer container to rotate to the upper limit photoelectric switch 4 under the forward rotation of the rotating rod 21; or when it rotates to the lower limit photoelectric switch 5 under the reverse rotation of the rotating rod 21, the upper limit photoelectric switch 4 and the lower limit photoelectric switch 5 will respectively control the external controller to drive the reduction motor 24 to stop working, thus respectively making the transfer container vertical and ready for feeding in a horizontal state. This is prior art and will not be described in detail here.

[0042] To ensure that the placement platform 23 rotates to a position level with the base plate of the device body 1, a buffer pad 50 is provided on the outer periphery of the lower limit photoelectric switch 5. The buffer pad 50 prevents the sides of the placement platform 23 and the main connecting rod 22 from directly contacting the side plate 11, preventing harsh collision noises and extending the service life of the rotating assembly 2. The buffer pad 50 is mainly made of flexible materials such as EVA foam, silicone pads, and air cushion films. Additionally, flexible materials such as EVA foam, silicone pads, and air cushion films can be placed inside the transfer container to provide cushioning for the transport of materials within the container, preventing damage caused by excessive collisions.

[0043] In some preferred embodiments, omnidirectional wheels 13 and directional wheels 12 are symmetrically arranged at the bottom of the device body 1. The directional wheels 12 are located below the side plate 11, and the omnidirectional wheels 13 are located away from the side plate 11. The omnidirectional wheels 13 drive the directional wheels 12 to rotate, moving the device body 1 away from or closer to the position to be transferred. At the same time, the omnidirectional wheels 13 are equipped with brakes to ensure that the device body 1 remains fixed during the feeding process, preventing movement that could lead to material transfer failure.

[0044] The working principle of this utility model is as follows: During use, the external controller is activated, causing the output end of the reduction motor 24 to rotate in the reverse direction until it reaches the upper limit photoelectric switch 4. The reduction motor 24 then stops working. At this time, the material enters the transfer container. When the photoelectric sensor 3 detects the material in the transfer container, it drives the reduction motor 24 to work, causing its output end to rotate slowly and uniformly in the forward direction. This ensures that the inlet of the transfer container and the outlet of the conveying device are at the same height difference. When the photoelectric sensor 3 or the placement platform 23 is on the same plane as the lower limit photoelectric switch 5, the external controller is activated to shut off the reduction motor 24, thus completing the material transfer. After the material has been transported from the transfer container, this step is repeated. This ensures that the material is always transported at the same height difference, maintaining the integrity of the material during transport, avoiding collisions between products, and improving the product qualification rate.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
