Description

[0001] Technical Field

[0002] This utility model relates to the field of shelving technology, specifically a shelving unit with a weight sensing structure.

[0003] Background Technology

[0004] As an important storage and logistics warehousing equipment, shelving plays a crucial role in modern warehouse management. In order to maximize the use of limited space resources and increase storage capacity, shelving is often designed with more layers to accommodate more items. This multi-layer design not only optimizes space utilization but also greatly improves warehousing efficiency. With the continuous advancement of technology, especially the rapid development of electronic technology, the functions of shelving are constantly being improved and enhanced. Modern shelving is not just a simple storage tool; it has been endowed with more intelligent functions.

[0005] A shelf with a sensing function for goods is disclosed in CN208892110U, including a support frame; a pallet installed on the support frame; two or more parallel shelf panels installed above the pallet for placing goods; and a weight sensing device disposed between a shelf panel and a pallet, with its lower surface at one end connected to the pallet and its upper surface at the other end connected to the shelf panel. The shelf also includes a support member disposed between the weight sensing device and the shelf panel, with its upper part connected to the lower surface of the shelf panel and its lower part connected to the upper surface of one end of the weight sensing device. While this shelf has a certain degree of weight sensing function, its structure is complex and inconvenient for removing items.

[0006] Existing shelving systems store goods by placing them on the shelves and using weight sensors to determine if the shelves have reached their load-bearing capacity. However, in practice, if the shelves are overloaded, some goods need to be removed to reduce the weight. This process is inconvenient because removing overloaded goods from the shelves is difficult. Therefore, once goods are placed on the shelves, it's not easy to retrieve them, resulting in poor convenience and automation in the entire placement process. Utility Model Content

[0007] The purpose of this invention is to provide a shelf with a weight-sensing structure to at least solve one of the following problems existing in the prior art. This shelf has a simple structure, facilitates the removal and placement of goods, and effectively solves the problem of existing shelves being difficult to remove from the shelf when overloaded.

[0008] To achieve the purpose of this utility model, the specific technical solution adopted is as follows:

[0009] A shelf with a weight-sensing structure includes: a load-bearing frame, a support frame fixedly connected to the outer side of the load-bearing frame, and a conveyor belt rotatably mounted above the load-bearing frame. One end of the conveyor belt is connected to a forward and reverse motor. A chute frame is fixedly mounted on the outer side of the conveyor belt, and a flat plate is slidably mounted on the surface of the chute. A base is fixedly mounted on the upper surface of the flat plate, and a weight sensor is installed inside the base. A pressure sleeve is slidably mounted above the base via a spring, and a pressure plate is connected above the pressure sleeve. A support platform is fixedly mounted above the pressure plate, and a placement platform is fixedly mounted above the support platform.

[0010] As a further improvement of this utility model, the flat plate and the slide rail frame form a sliding structure.

[0011] As a further improvement of this utility model: the internal structural dimensions of the pressure sleeve match the external structural dimensions of the base, and the pressure sleeve and the upper end of the base are sleeved together.

[0012] As a further embodiment of this utility model: a rubber protective ring is provided between the pressure plate and the pressure sleeve, and a connecting rod is rotatably connected to the outer side of the pressure sleeve. A roller is rotatably installed at the lower end of the connecting rod, and an adjusting rod is rotatably connected to the middle of the connecting rod.

[0013] As a further embodiment of this utility model: the lower end of the adjusting rod is rotatably connected to the outer wall of the base, and both the adjusting rod and the connecting rod are arranged in a ring about the symmetrical center line of the base.

[0014] As a further embodiment of this utility model: a pad is fixedly connected to the right end of the slide frame, and the pad is rotatably connected to the forward and reverse motor, while the pad is fixedly connected to the load-bearing frame.

[0015] As a further improvement of this utility model, the load-bearing frame has N layers, where N≥1, such as 2, 3, 4, 5, 6 layers, etc.

[0016] As a further improvement of this invention, the weight sensor is connected to a control device. The control device, being existing technology, transmits the data sensed by the weight sensor to the controller (display), allowing for better differentiation of which location of the goods has changed, thus enhancing practicality. It also facilitates inventory management by directly sensing changes in the weight of the goods.

[0017] Compared with the prior art, the main advantages of this utility model are as follows:

[0018] A conveyor belt is installed on the load-bearing platform, and the conveyor belt is connected to the pulley and the forward and reverse motors. The forward and reverse motors drive the conveyor belt to move. A flat plate is installed on the surface of the conveyor belt, and a pressure plate is installed on the flat plate. A pressure sleeve is connected below the pressure plate. A support platform and a placement platform are set above the pressure plate. When the goods are placed on the placement platform, the weight will press down on the pressure plate, and the pressure plate will press down on the pressure sleeve. The connecting rod and adjusting rod connected to the outside of the pressure sleeve cooperate with each other to fold the pressure sleeve, so that the pressure sleeve will press down on the weight sensor. The weight sensor is used to sense the weight of the goods. When the accumulated weight exceeds the limit, the forward and reverse motors rotate in the opposite direction, and the conveyor belt moves in the opposite direction, thereby pushing the goods placed in the shelf back out. This allows for the addition and removal of goods on the placement platform, making the picking and placing process more convenient and facilitating weight control. Attached Figure Description

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this application. As used herein, the singular form includes the plural form unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this description, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] In this utility model, some conventional operating equipment, devices and components have been omitted or only briefly described.

[0028] Unless otherwise specified in the examples, the conditions shall be performed according to the standard conditions or the conditions recommended by the manufacturer.

[0029] Example 1:

[0030] See Figures 1-4 This embodiment provides a shelf with a weight sensing structure.

[0031] The shelving includes: a load-bearing frame 1, a support frame 2 fixedly connected to the outside of the load-bearing frame 1, and a conveyor belt 5 rotatably mounted on the top of the load-bearing frame 1. One end of the conveyor belt 5 is connected to a forward and reverse motor 9. A slide rail frame 4 is fixedly mounted on the outside of the conveyor belt 5, and a flat plate 6 is slidably mounted on the surface of the slide rail. A pad 3 is fixedly connected to the right end of the slide rail frame 4, and the pad 3 is rotatably connected to the forward and reverse motor 9. The pad 3 is fixedly connected to the load-bearing frame 1.

[0032] Specifically, the load-bearing platform and the support frame 2 are fixedly connected, and the two cooperate to form a basic support structure. The sled frame 4 and the conveyor belt 5 are supported and installed through the setting of the pad platform 3. The conveyor belt 5 is driven by the forward and reverse motor 9 to move forward and reverse. Through the forward and reverse movement of the conveyor belt 5, the plate 6 and the sled frame 4 are in a sliding structure when the conveyor belt 5 is moving. This allows the goods on the plate 6 to be moved into the interior of the load-bearing frame 1 in cooperation with the conveyor belt 5, realizing the entry and exit of goods, improving the convenience of goods placement and automatic retrieval and placement.

[0033] A base 17 is fixedly installed on the upper surface of the plate 6, and a weight sensor 16 is installed inside the base 17. A pressure sleeve 12 is slidably installed on the top of the base 17 via a spring, and a pressure plate 10 is connected to the top of the pressure sleeve 12. A support platform 7 is fixedly installed on the top of the pressure plate 10, and a placement platform 8 is fixedly installed on the top of the support platform 7. The plate 6 and the slide frame 4 form a sliding structure. The internal structural dimensions of the pressure sleeve 12 match the external structural dimensions of the base 17, and the upper ends of the pressure sleeve 12 and the base 17 are sleeved together. A rubber protective ring 11 is provided between the pressure plate 10 and the pressure sleeve 12, and a connecting rod 13 is rotatably connected to the outer side of the pressure sleeve 12. A roller 14 is rotatably installed at the lower end of the connecting rod 13, and an adjusting rod 15 is rotatably connected to the middle of the connecting rod 13. The lower end of the adjusting rod 15 is rotatably connected to the outer wall of the base 17, and the adjusting rod 15 and the connecting rod 13 are both distributed in a ring about the symmetrical center line of the base 17.

[0034] Specifically, goods are placed sequentially on the placement platform 8. The weight of the goods presses down on the placement platform 8. A pressure plate 10 is installed below the placement platform 8. When the pressure plate 10 is under pressure, it presses down on the pressure sleeve 12. The pressure sleeve 12 is connected to the base 17 by a spring. As the pressure sleeve 12 continues to press down, the rotating structure of the connecting rod 13 and the adjusting rod 15 on the outside of the pressure sleeve 12 will cooperate with the movement of the pressure sleeve 12 to achieve folding. The connecting rod 13 and the adjusting mechanism are mainly used to support the pressure sleeve 12, preventing the weight sensor 16 from being pressed down directly after the goods are placed on it. Only when a certain weight is reached will the pressure sleeve 12 press down and touch the weight sensor 16, which can not only provide support, but also sense the weight of the goods on the placement platform 8 in conjunction with the downward movement of the pressure sleeve 12. If the weight exceeds the limit, the forward and reverse motor 9 drives the conveyor belt 5 to move in the opposite direction, thereby removing the goods from the support frame 1. The weight of the placement platform 8 can be controlled by adding or removing goods on the placement platform 8.

[0035] As a further improvement of this invention, the weight sensor 16 is connected to a control device (PLC system). The control device, being existing technology, transmits the data sensed by the weight sensor to the controller (display), allowing for better differentiation of which location of the goods has changed, thus enhancing practicality. It also facilitates inventory management by directly sensing changes in the weight of the goods.

[0036] The working principle of this utility model is as follows:

[0037] When using this invention, the goods are first placed on the placement platform 8. The weight of the goods is transmitted to the pressure plate 10 through the support platform 7. After the pressure plate 10 is subjected to pressure, it pushes the pressure sleeve 12 downward. The pressure sleeve 12 is connected to the base 17 by a spring. The spring provides a certain buffering effect when the pressure sleeve 12 is subjected to pressure, avoiding direct impact on the weight sensor 16. As the pressure sleeve 12 continues to press down, the connecting rod 13 and adjusting rod 15 on the outside of the pressure sleeve 12 begin to rotate, folding in conjunction with the movement of the pressure sleeve 12, thereby gradually reducing the gap between the pressure sleeve 12 and the base 17. When the weight of the goods reaches a certain level, the pressure sleeve 12 will eventually touch the weight sensor 16. At this time, the weight sensor 16 will send a signal indicating that the weight of the goods has been sensed. When the weight exceeds the predetermined range, the PLC system will start the forward and reverse motor 9. Through the driving action of the motor, the conveyor belt 5 will move in the forward and reverse directions. This forward and reverse movement allows the goods to be removed from the support frame 1. The operator can add or remove goods on the placement table 8 to adjust the weight on the placement table 8 in this way to ensure that it meets the set standard. The circuit connection system between the PLC system and the weight sensor 16 is disclosed in the existing publication number CN105858121A. It belongs to the prior art, so no further details are made.

[0038] Example 2:

[0039] Under the premise of Embodiment 1, a shelf with a weight-sensing structure is provided, wherein the load-bearing frame 1 has 4 layers, and the structure of each layer of the load-bearing frame 1 is the same. Of course, the load-bearing frame 1 can also have 5 layers, 6 layers, etc. The only difference is that the weight sensor 16 of each layer is connected to the PLC system.

[0040] The overall structure uses a weight sensor 16 to detect the load-bearing weight of the shelf in real time. All components work together to ensure weighing stability and structural reliability.

[0041] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.

[0042] The background section is provided to generally present the context of this utility model. The work of the currently named inventors, the work to the extent described in this background section, and aspects described in this section that did not constitute prior art at the time of filing are neither expressly nor impliedly acknowledged as prior art to this utility model.
