Description

Technical Field

[0001] This utility model relates to the field of material transfer equipment, and in particular to a starting element and a material docking device. Background Technology

[0002] Materials is a professional term in my country's production sector. Manufacturing enterprises typically refer to all materials (regardless of whether they come from means of production or means of subsistence), fuel, parts, semi-finished products, outsourced components, as well as scraps, waste, and various types of waste that are inevitably generated during the production process, other than the final product, as "materials".

[0003] In traditional industrial manufacturing, materials typically need to be transferred to specific workstations to complete assembly and processing. Currently, the most common material transfer method uses synchronous belt conveyor systems, which work by using a motor to drive rollers, which in turn move the synchronous belt. However, synchronous belts and their drive components are generally quite complex in structure, often used as independent modules or integrated into shelving, resulting in a large overall footprint and limiting layout flexibility and space utilization efficiency. Utility Model Content

[0033] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0034] This utility model provides a starting component for use on a material rack to assist in the transfer of material boxes on the material rack. It includes: a fixed box 303 with through holes on both sides; and a transmission assembly including a transmission shaft 304, a motor 302, and rollers. The two ends of the transmission shaft pass through the through holes on both sides of the fixed box, the motor is installed inside the fixed box and connected to the transmission shaft, and the rollers are mounted on the transmission shaft.

[0035] Specifically, the mounting box 303 refers to a housing structure with accommodating and protective functions. It can be made of metal or high-strength plastic, and its purpose is to provide a stable installation environment for internal components and isolate them from external interference. The through hole is a through-hole formed in the mounting box 303. Its shape and size can be adapted to the specific specifications of the drive shaft 304, aiming to achieve precise positioning and stable support for the drive shaft 304. The drive shaft 304 is a rod-shaped component used to transmit power. The design with rollers 301 at both ends enables a single power source to synchronously drive multiple actuators.

[0036] In detail, this solution constructs an integrated power transmission system through the combination of a fixed box 303 and a drive shaft 304. The fixed box 303 not only provides a closed installation space for the motor 302 but also axially limits the drive shaft 304 through through-holes, ensuring the positional accuracy of the drive shaft 304. The motor 302 and drive shaft 304 are directly connected inside the fixed box 303; this layout effectively avoids interference from external factors on the power transmission path. The starting component 3 adopts an integrated design where the motor 302 directly drives the roller 301, replacing the traditional three-stage transmission structure of motor 302-roller-synchronous belt, reducing the number of intermediate connecting parts in the transmission chain. The rotational motion of the roller 301 directly acts on the bottom contact surface of the material box 4, forming a compact drive unit, while eliminating the tension space required for belt drive, thus reducing the overall size of the device. The motor 302 of the starter 3 directly drives the roller 301, which realizes the structural optimization of the material transfer system. While ensuring the integrity of the function, it breaks through the space limitation of the traditional conveying system and solves the problem of insufficient layout flexibility caused by the complex structure and large space occupation of the traditional material transfer device. At the same time, it improves the efficiency and space utilization of the material docking process.

[0037] In some embodiments, a first washer 307 and a second washer 308 are provided on the drive shaft, and the roller is fixed between the first washer 307 and the second washer 308.

[0038] In practice, a first washer 307 and a second washer 308 are installed on the drive shaft to fix the roller between the first washer 307 and the second washer 308. The roller rotates directly with the first washer 307 and the second washer 308. The first washer 307 and the second washer 308 rotate with the drive shaft. The first washer 307 and the second washer 308 mainly serve to fix the roller.

[0039] Specifically, the first washer 307 is made of metal, and the roller is made of plastic. The first washer 307 is connected to the drive shaft, and the second washer 308 is used to assist in fixing the roller to the first washer 307. The first washer 307 has a screw hole, and the second washer 308 and the roller have through holes. The first washer 307 is connected to the drive shaft, and then the roller is installed on the drive shaft and tightly against the first washer 307. Then the second washer 308 is installed on the drive shaft and tightly against the roller. A screw is then passed through the through holes on the first washer 307 and the roller and screwed into the screw hole of the first washer 307 to fix the roller between the first washer 307 and the second washer 308.

[0040] In some embodiments, a pin is provided on the drive shaft, and a groove is provided on the first washer 307, with the end of the pin being engaged in the groove.

[0041] In practice, a pin is installed on the drive shaft, and the pin is inserted into the first washer 307 to fix the first washer 307 on the drive shaft. The drive shaft is driven by the motor and drives the first washer 307 through the pin.

[0042] Compared with the prior art, the transmission shaft in the prior art usually drives the roller directly to the roller body through a pin. However, the roller body is usually made of plastic, which is easily damaged under the direct drive of the transmission shaft for a long time. In this application, the first washer 307 is directly connected to the transmission shaft. The first washer 307 and the second washer 308 are used to fix the roller and move the roller. The transmission shaft does not directly act on the roller. In addition, the first washer 307 in this application is made of metal. Its direct connection with the transmission shaft is not easily worn in practical applications, which indirectly protects the structure of the roller.

[0043] Furthermore, the outer ring of the roller is fitted with a rubber ring, which can increase the friction between the roller and the material box when the roller drives the material box.

[0044] In some embodiments, the fixing box is provided with a connecting seat 309, the connecting seat 309 is provided with a through hole, the motor is provided with a screw hole, and the motor is fixed to the connecting seat 309 by screws.

[0045] During implementation, the motor is fixed to the connector 309 with screws to stabilize the motor inside the mounting box.

[0046] Furthermore, the connecting seat 309 is an integral extension of the inner wall of the fixing box. The fixing box includes an upper cover 310 and a lower cover 311. The upper cover 310 is detachably installed on the top of the fixing box, and the lower cover 311 is detachably installed on the bottom of the fixing box.

[0047] Compared with the prior art, the structure of fixing the motor in the prior art is complicated, resulting in a large overall structure volume. However, in this application, there is no need to set up a separate fixing structure. The connecting seat 309 and the fixing box are integrally formed, which is simpler in terms of manufacturing process and structure. It is only necessary to set a screw hole on the motor and fix it to the connecting seat 309 in the fixing box with screws. The installation method is also simple.

[0048] In some embodiments, the motor is connected to a conventional shaft via gear transmission.

[0049] Specifically, gear 305 transmission refers to a transmission method that uses the meshing of gears 305 to transmit power and motion. It can be implemented using combinations of different types of gears 305, such as spur gears 305, helical gears 305, or bevel gears 305. The purpose of introducing gear 305 transmission is to improve transmission efficiency, ensure the synchronization and stability of power transmission, reduce the size of the transmission mechanism, facilitate a compact layout of the overall device structure, and improve the convenience of later maintenance.

[0050] In detail, the rotational motion output by the motor 302 is precisely transmitted to the drive shaft 304 via the gear 305, thereby driving the roller 301 to rotate. The rigid meshing characteristic of the gear 305 avoids the slippage that may occur in traditional belt drives, ensuring the reliability of power transmission. Furthermore, the design of the gear 305 drive allows the transmission mechanism to be integrated modularly within the fixed box 303, effectively reducing space occupation. On this basis, the detachable nature of the gear 305 drive allows for the replacement of only specific gear 305 components during maintenance, without disassembling the entire device, significantly improving equipment maintenance efficiency. This design, together with the fixed box 303, drive shaft 304, and roller 301 in the starting component 3, further optimizes the overall performance of the material handling device, solving the problems of low transmission efficiency, complex structure, and difficult maintenance inherent in traditional direct drive methods, and providing strong support for the stability of the device's operation.

[0051] This application provides a material docking device, including: a fixed frame 1 with a first compartment 101 on the top; a movable frame 2 with a second compartment 201 on the top, the first compartment 101 docking with the second compartment 201; and a starting element 3 installed in the second compartment 201, including a roller 301 and a motor 302, the motor 302 being connected to the roller 301.

[0052] In practical applications, the fixed frame 1 can be understood as a structure for support and positioning. It can be implemented through multiple columns or frames, such as using metal profiles spliced ​​into a rectangular frame structure, or forming an integrated support through welding. The first compartment 101, as the basic platform for material storage or transportation, can be composed of multiple horizontally arranged support bars or bearing plates. Specifically, these support bars or bearing plates can be arranged in parallel to form a stable bearing surface. The movable frame 2 can also be understood as a structure for support and positioning, but the movable frame 2 is movable relative to the fixed one. The starting component 3, as the core component for power transmission, can use various means to connect the motor 302 and the roller 301. For example, it can directly connect the motor 302 shaft and the roller 301 shaft through a coupling, or use gear 305 to transmit the power of the motor 302 to the roller 301. This is mainly to achieve efficient power transmission and simplify the mechanical structure.

[0053] The working principle of this embodiment is as follows: A first compartment 101 is set on the top of the fixed frame 1, serving as a basic platform for material storage or conveying, used to receive and temporarily store materials to be transferred. A second compartment 201 is set on the top of the movable frame 2. The displacement of the movable frame 2 enables the second compartment 201 to dock with the first compartment 101, thereby forming a material conveying channel. The second compartment 201 is used to place the material box 4, which is used to store materials to be processed. This docking design eliminates the fixed track layout of the traditional synchronous belt system, enabling the material conveying path to have dynamic adjustment capability. The starting element 3 is installed in the second compartment 201, including a roller 301 and a motor 302. The motor 302 is directly connected to the roller 301, and the motor 302 drives the roller 301 to rotate to realize the conveying of materials. That is, the roller 301 contacts the bottom of the material box 4, and the roller 301 rolls to move the material box 4 from the second compartment 201 to the first compartment 101.

[0054] The fixed frame 1 has a first compartment 101 on top, serving as a basic platform for material storage or conveying. The mobile frame 2 has a second compartment 201 on top, forming a movable docking channel. This docking design eliminates the fixed track layout of traditional synchronous belt systems, enabling dynamic adjustment of the material conveying path. The starting component 3 adopts an integrated design where the motor 302 directly drives the roller 301, replacing the traditional three-stage transmission structure of motor 302-roller-synchronous belt. By integrating the power source and transmission components into the second compartment 201, not only is the number of intermediate connecting parts in the transmission chain reduced, but the power transmission path is also transformed from a linear extension to a modular embedding, thereby breaking through the spatial limitations of traditional conveying systems.

[0055] Furthermore, the top of the fixed frame 1 is provided with multiple first compartments 101, and the top of the movable frame 2 is provided with multiple second compartments 201. The docking of the multiple first compartments 101 and the multiple second compartments 201 can improve the material transfer efficiency. The first compartment 101 is also provided with an actuating element 3. The actuating element 3 in the first compartment 101 is used to assist the material box 4 to enter the first compartment 101 more easily from the second compartment 201 or to reverse the process to transfer the material box 4 from the first compartment 101 to the second compartment 201. For example, if the material in the material box 4 has been used up and the material box 4 is in an empty box state, the actuating element 3 in the first compartment 101 can drive the material box 4 to transfer to the second compartment 201.

[0056] In some embodiments, the fixing frame 1 includes a plurality of first base columns 102, which are parallel to each other and connected by a first support column 103.

[0057] Specifically, the first base column 102 refers to the longitudinal support component used to form the main structure of the fixed frame 1. It can be implemented using cylindrical or square rods made of metal, with the purpose of providing the main load-bearing capacity in the vertical direction. The first support column 103 can be understood as a transverse component connecting adjacent first base columns 102. It can be a rectangular tube or an I-beam or other profile, with the purpose of connecting the base columns into an overall frame to enhance structural stability.

[0058] In detail, this solution achieves uniform load distribution through the parallel arrangement of multiple first base columns 102, improving the overall compressive strength of the mounting frame 1. First support columns 103 connect the base columns to form a stable frame structure. This combination not only enhances the bending and torsional resistance of the mounting frame 1 but also avoids the material waste associated with traditional monolithic supports. Through the standardized combination design of the first base columns 102 and first support columns 103, the dimensions of the mounting frame 1 can be flexibly adjusted according to actual needs, thereby improving layout flexibility. Furthermore, this modular design facilitates production and installation, helping to reduce manufacturing costs.

[0059] In the aforementioned material handling device, the fixed frame 1 serves as the supporting foundation for the first compartment 101, and its structural stability directly affects the reliability of the entire device. By employing multiple parallel first base columns 102, coupled with the reinforcement of the first support columns 103, the problem of insufficient structural stability is effectively solved, while optimizing space utilization. This design not only ensures the load-bearing capacity of the fixed frame 1 but also achieves a flexible and adjustable modular structure, significantly improving the overall performance of the material handling device.

[0060] In some embodiments, a first flow strip 104 is provided between the first support columns 103, and the first support columns 103, the first flow strip 104 and the first base column 102 together constitute the first storage space 101.

[0061] Specifically, the first flow strip 104 is a structural component with guiding and supporting functions. It can be made of metal or high-strength plastic, and the first flow strip 104 is equipped with guide wheels. The purpose of the first flow strip 104 is to fill the gaps between the first support columns 103 and provide a smooth sliding path for the material. The first base column 102, as the main load-bearing structure, can be fixed to the first support columns 103 by welding or sleeve connection, thereby forming a stable frame system.

[0062] In detail, the introduction of the first flow bar 104 not only optimizes the space utilization of the first compartment 101, but also enhances the stability of material storage through its unique guiding characteristics. The first support column 103 and the first base column 102 form a three-dimensional support network through multi-directional connections, a design that significantly enhances the overall rigidity of the first compartment 101. In practical applications, the length of the first flow bar 104 can be flexibly adjusted according to the spacing of the first support columns 103, thereby achieving a more compact spatial layout. Furthermore, the inclined design of the first flow bar 104 allows materials to slide naturally under gravity, reducing the need for manual intervention and providing necessary structural redundancy for the docking of the movable frame 2.

[0063] In some embodiments, a first guide post 105 and a blocking post 106 are provided between the first base posts 102 in the first compartment 101.

[0064] Specifically, the first guide post 105 refers to the physical boundary structure set on both sides of the material conveying path, which can be implemented using cylindrical, square, or other rigid components with regular cross-sectional shapes. In practical applications, the first guide post 105 corrects the material's trajectory in real time through contact feedback with the material, aiming to eliminate lateral displacement problems caused by uneven gravity distribution or deviations in the tilt angle of the flow channel. The blocking post 106 can be understood as a rigid stop structure, which is usually made of metal or high-strength plastic. It can be designed as a fixed or detachable structure, aiming to achieve precise positioning to terminate the movement by utilizing the collision with the material.

[0065] In detail, this solution constructs a dual constraint mechanism by adding a first guide post 105 and a blocking post 106 between the first base posts 102. The first guide post 105 is located on both sides of the material conveying path, forming a clear physical boundary. When the material slides on the first flow bar 104, if a directional deviation occurs, the material will come into contact with the first guide post 105. Based on the contact feedback, the movement trajectory is automatically adjusted, thereby ensuring that the material is stably conveyed along the predetermined path. The blocking post 106 is set at the end point of the conveying process. When the material slides to the end point, the blocking post 106 restricts the material from continuing to move through rigid stopping, preventing stacking chaos caused by inertia exceeding the predetermined position. In addition, the combined use of the first guide post 105 and the blocking post 106 not only improves the path controllability during the material conveying process, but also enhances the accuracy of the end point positioning, thereby significantly improving the stability and fault tolerance of the conveying system without adding additional drive components.

[0066] In some embodiments, the movable frame 2 includes a second base column 201, and a second support column 202 is provided between the second base columns 201.

[0067] Specifically, the second base column 201 refers to the vertical component that serves as the main load-bearing frame of the movable frame 2, and it can be made of high-strength steel or aluminum alloy profiles. In practical applications, the second base column 201 can be made of rectangular tubes, I-beams, or other profiles with excellent bending resistance, in order to provide sufficient vertical load-bearing capacity and effectively distribute the pressure load generated by the weight of the materials.

[0068] The second support column 202 can be understood as a horizontal component connecting the adjacent second base column 201, which can be made of round steel pipe, square steel pipe or angle steel and other profiles.

[0069] In detail, this scheme forms a spatial truss structure through the combination of the second base column 201 and the second support column 202, which can effectively improve the load-bearing capacity of the movable frame 2. The second base column 201 serves as the main load-bearing component, bearing the vertical load, while the second support column 202 connects each second base column 201 in the horizontal direction, together forming a stable three-dimensional support system. In particular, the modular units formed by the second support column 202 and the second base column 201 can be flexibly adjusted in arrangement density according to actual needs, ensuring both structural compatibility when docking with the fixed frame 1 and optimizing the spatial layout.

[0070] In some embodiments, a second flow strip 203 is provided between the second support columns 202, and the second base column 201, the second support column 202 and the second flow strip 203 constitute the second storage space 201.

[0071] The second flow strip 203 refers to a guide and support structure with a smooth surface, which can be made of metal or engineering plastic, with a polished surface or a ball bearing structure. In practical applications, the second flow strip 203 is usually designed as a long strip structure to provide a continuous support surface during material transport and reduce frictional resistance. The second base column 201, as the main load-bearing structure, can be a rectangular tube or an I-beam structure, designed to ensure the stability of the overall frame. The second support column 202 is a key component connecting the second base column 201 and supporting the second flow strip 203; it can be made of angle steel or channel steel, designed to form a stable support system.

[0072] Furthermore, the first flow bar 104 is inclinedly arranged within the first compartment 101. This inclined arrangement changes the direction of force on the material by forming a specific angle with the horizontal plane, thus effectively utilizing the gravitational component. This design aims to reduce reliance on external power and improve material transfer efficiency. The inclined arrangement of the first flow bar 104 on the first compartment 101 allows the material to slide naturally downwards along the inclined surface under gravity. The inclination angle of the first flow bar 104 is precisely calculated to ensure that the material can overcome frictional resistance and achieve self-driven movement, while avoiding excessively fast material descent due to an excessively large angle, which could affect docking accuracy. Simultaneously, the inclined first flow bar 104, together with the first base column 102 and the first support column 103, forms a guiding transfer channel in the first compartment 101, enabling the material to move stably along a predetermined path. This structural design not only simplifies the transmission system but also improves the continuity and stability of material transfer. Especially when the fixed frame 1 and the moving frame 2 dock, it enables natural material convergence and enhances the device's adaptability to different workstation height differences.

[0073] In some embodiments, the second support column 202 is provided with a clamping member 204 and two second flow strips 203. The clamping member 204 is located between the two second flow strips 203. The fixing box 303 is provided with a locking strip 306. The clamping member 204 and the locking strip 306 cooperate to fix it.

[0074] Specifically, clamping component 204 refers to a structural component that provides a mechanical limiting function, which can be implemented using elastic clips, threaded locking components, or snap-on fasteners. In practical applications, the design of clamping component 204 needs to be adapted according to the motion characteristics and vibration frequency of the moving frame 2 to ensure that it can maintain a good fixing effect under dynamic conditions. The locking strip 306, as an auxiliary fixing element, can be a strip-shaped structure with specific grooves or protrusions. Its purpose is to form a stable interlocking relationship with clamping component 204, thereby preventing displacement of the fixing box 303.

[0075] In detail, this solution uses a clamping member 204 on the second support column 202 and a locking strip 306 on the fixed box 303 to form a mechanical interlocking structure, effectively solving the problem of loosening of the starting member 3 that may occur during the movement of the moving frame 2. When the moving frame 2 moves the second compartment 201, the cooperation between the clamping member 204 and the locking strip 306 can resist axial or radial displacement caused by vibration and inertial force, thereby ensuring the connection stability between the motor 302 and the transmission shaft 304.

[0076] Furthermore, the clamping member 204 is provided with clamping openings at both ends, and the second support column 202 is also provided with a locking strip 306. The clamping opening at one end of the clamping member 204 is engaged with the locking strip 306 of the second support column 202, and the clamping opening at the other end of the clamping member 204 is engaged with the locking strip 306 fixed on it, thereby connecting the fixed box 303 to the second support column 202.

[0077] In some embodiments, the bottom of the mobile frame 2 is provided with casters 205.

[0078] During implementation, casters 205 are installed on the bottom of the mobile frame 2, allowing the mobile frame 2 to move on the ground.
