Description

Technical Field

[0001] This utility model relates to the field of product transfer technology, and in particular to a transfer device. Background Technology

[0002] In modern industrial production and logistics warehousing, efficient product flow is a key factor in ensuring overall operational efficiency. Gravity guideways, as a commonly used conveyor system, are widely applied in numerous production lines and warehouse racking systems due to their simple structure, low cost, and ability to enable unidirectional product sliding.

[0003] In existing technologies, gravity strip conveyor systems mainly consist of a gravity strip body, a support frame, and related fixing accessories. The gravity strip body is mounted on the support frame, forming a conveying channel with a certain inclination angle. The support frame serves to fix and support the gravity strip, ensuring the stability of the entire conveying structure. In practical applications, products are placed at one end of the gravity strip and slide towards the other end along the inclination direction of the gravity strip, relying on their own weight or slight external pushing, thereby realizing the flow of products.

[0004] However, due to the smooth surface of the flow strip and the relatively fixed conveying channel, the products lack an effective buffering and separation mechanism during the sliding process. When multiple products are placed on the flow strip consecutively, after the previous product slides to the end, the subsequent products will continue to be pushed forward due to inertia, causing the products to pile up, increasing the difficulty of picking up the products later, and may also cause the products to be damaged due to mutual squeezing, affecting product quality. Utility Model Content

[0005] The purpose of this utility model is to provide a transfer device that solves the problem in the prior art that products are prone to pile up during transfer, making it difficult to retrieve them later and potentially causing them to be damaged by squeezing each other.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a transfer device, which includes:

[0008] A frame extending along a first direction and having opposing first and second ends, wherein a plurality of rollers are arranged on the frame to slide the product from the first end to the second end;

[0009] A limiting component is disposed on the frame and distributed at intervals along the first direction. The limiting component includes a limiting part rotatably connected to the frame. The limiting part has a receiving state for receiving products and an isolation state for isolating products. In the isolation state, the limiting part abuts against the products received in the adjacent limiting part.

[0010] Optionally, one end of the limiting portion has a receiving protrusion and the other end has an isolating protrusion. In the receiving state, the receiving protrusion is higher than the isolating protrusion, and in the isolating state, the isolating protrusion is higher than the receiving protrusion.

[0011] Optionally, the limiting component further includes:

[0012] Mounting base, disposed on the rack;

[0013] A rotating shaft is disposed on the mounting base and passes through the limiting portion, and the rotating shaft is located between the receiving protrusion and the isolation protrusion.

[0014] Optionally, the limiting part has a limiting protrusion, and the mounting base has a limiting groove that engages with the limiting protrusion, the limiting groove extending along the rotation direction of the limiting part.

[0015] Optionally, the limiting component further includes:

[0016] A limiting rod is provided on the mounting base and corresponds to the side of the limiting part that is away from the receiving protrusion.

[0017] Optionally, the limiting part has a limiting hole on the side opposite to the receiving protrusion that engages with the limiting rod.

[0018] Optionally, the limiting component further includes:

[0019] An elastic element is connected to the limiting portion and has an elastic tendency to keep the limiting portion in the receiving state.

[0020] Optionally, the frame includes two oppositely arranged support frames, and the limiting component is located between the two support frames.

[0021] Optionally, one of the first end and the second end is rotatably connected to the machine base, and the other is rotatably connected to a lifting assembly.

[0022] Optionally, the lifting assembly includes:

[0023] Base;

[0024] The slider is slidably connected to the base in a vertical direction, and the slider is rotatably connected to the first end or the second end.

[0025] The beneficial effects of this utility model are:

[0026] When multiple products are placed sequentially on the rack, the rollers allow the products to slide from one end to the other. During this process, the limiting components are in a receiving state. When a product enters its corresponding limiting component, the component rotates and switches to an isolating state. In this isolating state, the limiting part abuts against the product in the adjacent limiting part, maintaining a certain distance between products in different limiting components. Therefore, when this transfer device is in use, after multiple products slide sequentially from one end to the other, the limiting components can separate adjacent products. This prevents product accumulation, facilitating quick retrieval by subsequent gripping structures such as robotic arms, and also prevents products from being damaged by mutual compression, ensuring that the quality of the products remains unaffected during the transfer process.

[0037] This utility model discloses a transfer device.

[0038] Reference Figures 1 to 3 The transfer device includes a frame 1 and a limiting assembly 2. The frame 1 extends along a first direction X and has a first end 11 and a second end 12 opposite to each other. A plurality of rollers 13 are arranged on the frame 1 to receive products 3 so as to slide the products 3 from the first end 11 to the second end 12. The limiting assembly 2 is disposed on the frame 1 and a plurality of them are distributed at intervals along the first direction X. The limiting assembly 2 includes a limiting part 21 rotatably connected to the frame 1. The limiting part 21 has a receiving state for receiving products 3 and an isolation state for isolating products 3. In the isolation state, the limiting part 21 abuts against the products 3 received in the adjacent limiting part 21.

[0039] Specifically, the frame 1 is elongated, with its first end 11 receiving the product 3, and its second end 12 being lower than the first end 11, allowing the product 3 to slide towards the second end 12 under its own weight. A baffle 14 is provided at the second end 12, and an elastic buffer block or similar structure is provided on the side of the baffle 14 closest to the product 3 to secure and protect the product 3 that arrives at the second end 12 first. To further reduce friction during the sliding of the product 3, multiple rollers 13 are distributed on the frame 1. It should be understood that a motor can also be used as a drive element, working in conjunction with a chain or other transmission structure to rotate the multiple rollers 13, thus transferring the product 3 from the first end 11 to the second end 12.

[0040] The limiting component 2 can be located inside or outside the frame 1, as long as it corresponds to the product 3. The limiting part 21 can be rotatably connected to the frame 1 via a shaft or similar structure. Rotation allows the limiting part 21 to switch between a receiving state and an isolating state. In the receiving state, a roller 13 protrudes from one side of the limiting part 21, allowing the product 3 to press against it when it slides to the limiting part 21, causing it to rotate and switch to the isolating state. In the isolating state, a roller 13 protrudes from the other side of the limiting part 21, ensuring that the newly placed product 3 is pressed against the limiting part 21. Multiple limiting components 2 can be spaced apart; the specific number can be designed according to the actual needs of picking up and placing the product 3, and this invention does not impose a limitation. In this embodiment, two limiting components 2 are provided only at the part near the second end 12, so that the two products 3 closest to the second end 12 on the rack 1 are separated by the two limiting components 2, and the remaining products 3 are attached to each other in sequence, so that the rack 1 can accommodate a sufficient number of products 3.

[0041] When multiple products 3 are placed sequentially on the frame 1, the rollers 13 allow the products 3 to slide from the first end 11 to the second end 12. At this time, the limiting components 2 are in the receiving state. When a product 3 enters the corresponding limiting component 2, the limiting component 2 rotates and switches to the isolation state. In the isolation state, the limiting part 21 can abut against the product 3 in the adjacent limiting part 21, thereby maintaining a certain distance between the products 3 in different limiting components 2. Therefore, when this transfer device is in use, after multiple products 3 slide sequentially from the first end 11 to the second end 12, the limiting components 2 can separate two adjacent products 3. On the one hand, this can prevent the products 3 from piling up, making it convenient for subsequent gripping structures such as robotic arms to quickly pick up the products 3. On the other hand, it can also prevent the products 3 from squeezing each other and damaging the products 3, ensuring that the quality of the products 3 is not affected during the transfer process.

[0042] Optionally, one end of the limiting part 21 has a receiving protrusion 211 and the other end has an isolating protrusion 212. In the receiving state, the receiving protrusion 211 is higher than the isolating protrusion 212, and in the isolating state, the isolating protrusion 212 is higher than the receiving protrusion 211.

[0043] Specifically, the limiting part 21 is elongated, and a receiving protrusion 211 is formed at one end of its top wall. A receiving slope can be provided on the side of the receiving protrusion 211 facing the first end 11, and the top wall of the receiving protrusion 211 can be flat to receive the product 3. An isolation protrusion 212 is formed at the other end of its top wall. A space for accommodating the product 3 is formed between the isolation protrusion 212 and the receiving protrusion 211. This space is larger than the width of the product 3 to ensure that the product 3 can be completely above the limiting part 21.

[0044] By setting the receiving protrusion 211 and the isolating protrusion 212, when the product 3 slides in, the receiving protrusion 211 is higher. As the product 3 slides in, the product 3 can squeeze the receiving protrusion 211, thereby pushing the limiting part 21 to rotate, so that the isolating protrusion 212 rises. Then the limiting part 21 will switch to the isolation state. At this time, when a new product 3 slides in, since the height of the isolating protrusion 212 is higher than that of the receiving protrusion 211, the newly slid-in product 3 will abut against the isolating protrusion 212, thereby separating the two adjacent products 3.

[0045] Optionally, the limiting component 2 also includes a mounting base 22 and a rotating shaft 23. The mounting base 22 is disposed on the frame 1; the rotating shaft 23 is disposed on the mounting base 22 and passes through the limiting part 21, and the rotating shaft 23 is located between the receiving protrusion 211 and the isolation protrusion 212.

[0046] Specifically, the mounting base 22 includes a base plate 221 and a mounting block 222. The base plate 221 is elongated, with one side fixedly connected to the frame 1 and the other side fixedly connected to the bottom wall of the mounting block 222. The fixing method can be bolt connection, snap-fit, adhesive bonding, or welding. The top wall of the mounting block 222 has a downward-facing groove, making the mounting block 222 U-shaped. The limiting part 21 is inserted into the groove, and the rotating shaft 23 passes through the mounting block 222 and the limiting part 21, so that the limiting part 21 and the mounting block 222 form a rotatable connection, and the rotating shaft 23 is located at the middle of the limiting part 21 along its length. To improve the limiting effect, the side wall of the limiting part 21 slides against the side wall of the groove to prevent the limiting part 21 from shifting during rotation.

[0047] Optionally, the limiting part 21 has a limiting protrusion 24, and the mounting base 22 has a limiting groove 223 that engages with the limiting protrusion 24, the limiting groove 223 extending along the rotation direction of the limiting part 21.

[0048] Specifically, the limiting protrusion 24 can be formed by protruding from the side of the limiting part 21, or it can be implemented by a pin. A through hole is opened on the mounting block 222 as a limiting groove 223, and the limiting protrusion 24 passes through the limiting groove 223. The extension length of the limiting groove 223 only needs to meet the rotation range when the limiting part 21 switches states. The specific extension length can be designed according to actual needs, and this utility model does not limit it.

[0049] By setting the limiting protrusion 24 and the limiting groove 223, on the one hand, when installing the limiting part 21, the limiting protrusion 24 is first inserted into the limiting groove 223 so that the limiting part 21 is pre-connected with the mounting plate, and then the rotating shaft 23 is passed through the mounting block 222 and the limiting part 21 to reduce the assembly difficulty. On the other hand, when the limiting part 21 rotates, it can drive the limiting protrusion 24 to slide in the limiting groove 223. Then the extension length of the limiting groove 223 can limit the rotation range of the limiting protrusion 24, thereby limiting the rotation range of the limiting part 21 and ensuring that the rotation range of the limiting part 21 can only meet the switching between the receiving state and the isolation state.

[0050] Optionally, the limiting assembly 2 also includes a limiting rod 25. The limiting rod 25 is disposed on the mounting base 22 and corresponds to the side of the limiting part 21 opposite to the receiving protrusion 211.

[0051] Specifically, a support strip 224 extends outward from the sidewall of the base plate 221. The support strip 224 corresponds vertically to the receiving protrusion 211 of the limiting part 21, and the limiting rod 25 is located at the end of the support strip 224 away from the base plate 221. The bottom wall of the limiting rod 25 is fixedly connected to the support strip 224, and the fixed connection can be achieved by threaded connection, snap-fit, adhesive, or welding. The upper end of the limiting rod 25 extends vertically and can abut against the bottom wall of the limiting part 21 to further restrict the rotation of the limiting part 21. It should be understood that the limiting rod 25 can be made of an elastic material, that is, it can deform to a certain extent when compressed, so as to buffer the rotation of the limiting part 21.

[0052] By setting the limiting rod 25, when the product 3 is received by the receiving protrusion 211 of the limiting part 21, the limiting part 21 rotates and the bottom wall abuts against the limiting rod 25, thereby making the receiving protrusion 211 of the limiting part 21 abut against the product 3, so as to improve the stability of the product 3 in the limiting component 2.

[0053] Optionally, the limiting part 21 has a limiting hole 213 on the side opposite to the receiving protrusion 211 that engages with the limiting rod 25.

[0054] Specifically, a blind hole is made on the side of the limiting part 21 near the limiting rod 25 as a limiting hole 213. The length of the limiting rod 25 is greater than the depth of the limiting hole 213. In this way, the length of the limiting rod 25 can be appropriately increased without affecting the rotation range of the limiting part 21, which facilitates the processing and installation of the limiting rod 25.

[0055] Optionally, the limiting component 2 also includes an elastic element. The elastic element is connected to the limiting part 21 and has an elastic tendency to keep the limiting part 21 in a receiving state.

[0056] Specifically, the elastic element can be a torsion spring, which can be mounted on the rotating shaft 23 and connected to the limiting part 21, or it can be a spring, which is connected to the bottom wall of the limiting part 21 and the side near the isolation protrusion 212, so that the limiting part 21 always remains in the receiving state when the product 3 has not slid in. The specific location and type of the elastic element are not limited in this utility model.

[0057] Reference Figure 4 Optionally, the frame 1 includes two oppositely arranged support frames 15, and the limiting component 2 is located between the two support frames 15.

[0058] Specifically, the bottom walls of the two receiving frames 15 can be detachably connected via a connecting plate 16, allowing the spacing between the two receiving frames 15 to be adjusted according to the width of the product 3. Each receiving frame 15 is equipped with multiple rollers 13, and a stop bar 17 is provided on the outer side of each receiving frame 15. The stop bar 17 slides against the side of the product 3 to limit the product 3 along its length. A lubricating layer or ball bearings can be provided on the side of the stop bar 17 to reduce friction between the product 3 and the stop bar 17. The limiting component 2 is positioned between the two receiving frames 15, making it built into the entire device to further reduce space occupation. It also provides abutment at the center of the product 3 to prevent the product 3 from shifting.

[0059] Optionally, of the first end 11 and the second end 12, one is rotatably connected to the machine base, and the other is rotatably connected to the lifting assembly 4.

[0060] Specifically, taking the example of the first end 11 of the frame 1 being rotatably connected to the machine base, a connecting plate 16 is provided on the lower side of the first end 11 of the frame 1. The connecting plate 16 is rotatably connected to a fixing block 18 via a hinge. The fixing block 18 is fixedly connected to the machine base by bolts or snap-fit ​​connections. The machine base can be a workbench of adjacent equipment or other structures, and this utility model does not limit this. The connecting plate 16 located at the second end 12 is rotatably connected to the lifting assembly 4. The lifting assembly 4 can be a lifting cylinder or a motor screw, etc., so that the second end 12 can be raised or lowered to adjust the relative height of the first end 11 and the second end 12. In other embodiments, the second end 12 of the frame 1 can also be rotatably connected to the machine base, while the lifting assembly 4 is provided at the first end 11.

[0061] The relative height of the first end 11 and the second end 12 can be adjusted by the lifting component 4 so that the second end 12 is lower than the first end 11. After the product 3 is placed on the frame 1, the product 3 can slide from the first end 11 to the second end 12 by its own weight without the need for a drive structure. This makes the structure of the whole device simple, the cost low and easy to implement.

[0062] Optionally, the lifting assembly 4 includes a base 41 and a slider 42. The slider 42 is slidably connected to the base 41 in a vertical direction, and the slider 42 is rotatably connected to the first end 11 or the second end 12.

[0063] Specifically, taking the rotatable connection between slider 42 and second end 12 as an example, a hinge is provided on the connecting plate 16 of second end 12, and the hinge is fixedly connected to slider 42, so that slider 42 and second end 12 form a sliding connection. The base 41 can be fixed on the corresponding platform, and slider 42 can also be equipped with drive modules such as cylinders and motor screws to drive its sliding, thereby flexibly adjusting the height of second end 12.

[0064] When product 3 needs to move on the frame 1, the slider 42 is slid according to the weight of product 3 to raise or lower the second end 12 of the frame 1, thereby adjusting the tilt of the frame 1 and adjusting the sliding speed of product 3. On the one hand, this ensures that product 3 can slide smoothly to the second end 12, and on the other hand, it reduces the possibility of product 3 being damaged due to collision caused by excessive sliding speed.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
