Description

Technical Field

[0001] This utility model relates to the field of equipment and devices for garment conveyor lines, specifically a side-mounted guide rail conveyor assembly for a quiet and low-wear garment production line. Background Technology

[0002] The hanging system of a garment production line is an automated material handling system, mainly composed of tracks, hangers, drive units, control systems, and suspension devices. Its working principle involves placing the cut garment parts on hangers, suspending them on tracks, and then using the drive unit to move the hangers along the tracks. The control system precisely allocates workstations, enabling the automatic flow of garments between sewing, ironing, and other processes. This system offers significant advantages: it greatly improves production efficiency, reduces manual handling time and labor intensity; its tracks are installed on the ceiling, optimizing workshop space layout; and it also helps improve garment quality control, allowing for timely detection and handling of quality problems. Widely used in various garment production processes, it is a key means for garment factories to achieve automated and modernized production.

[0003] For example, the automated production line push rod assembly disclosed in Chinese utility model patent application CN202120960370.5 is installed inside the main track and connected to the rack at the top. It includes a push rod seat, a front locking block and a rear locking block located on the front and rear sides of the push rod seat. The rear locking block is equipped with a limiting roller, which abuts against the inner surface of the main track. This automated production line push rod assembly, by adding two limiting rollers, effectively solves the problem of the push rod moving downwards and the rack twisting under force when subjected to reaction force. For example, Chinese utility model patent application CN202320354625.2 discloses a vehicle driving device, which includes a pushing component on a drive chain and a limiting component on the drive chain opposite to the pushing component. A receiving area for accommodating the vehicle is provided between the pushing component and the limiting component. A transport channel for the vehicle to enter the receiving area is provided below the limiting component. The limiting component can open or close the transport channel. Driven by the drive chain, the pushing component pushes the vehicle located in the receiving area to move on the side-mounted track. In this utility model, the pushing component and the limiting component enclose the receiving area for accommodating the vehicle. When the pushing component pushes the vehicle on the side-mounted track, the limiting component restricts the vehicle within the receiving area, ensuring that the vehicle maintains synchronization with the pushing component during operation. This achieves both vehicle transportation and restriction of the vehicle's movement on the side-mounted track, meeting the needs of different processes.

[0004] In most existing guide rail devices used in garment conveyor lines, the roller components that support the hangers and garments are directly connected to the track components. Considering the structural strength and stability of the guide rail under load, these components are typically made of aluminum alloy or stainless steel; while the roller components, to better meet the requirements of flexibility and lightweight operation during rotation, are generally made of high-strength plastic. However, the applicant has found that when the roller components bear an external load and move along the track driven by the chain, the continuous friction between the roller surface and the guide rail surface generates debris and powder, which contaminates the material carried below. Furthermore, when the rollers change direction or transition between different track sections during movement, small-amplitude bounces and collisions are prone to occur, resulting in noise.

[0005] To address the aforementioned issues, this invention provides a quiet, low-wear side-mounted guide rail conveyor assembly for garment production lines. By setting an elastic material layer between the hanging guide rail portion on the supporting guide rail and the traveling roller, wear between components is significantly reduced, improving the durability and reliability of the conveyor system. Simultaneously, the noise generated when the rollers, bearing external loads, move or experience bouncing or collisions can be effectively absorbed. Utility Model Content

[0029] The following specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.

[0030] This solution is achieved through the following technical means:

[0031] Example: In this example, a quiet, low-wear side-mounted guide rail conveyor assembly for a garment production line is provided. This assembly mainly comprises three parts: a support guide rail 1, a drive chain 3, and a lateral mounting bracket 2 movably mounted on the support guide rail 1. (Refer to the appendix of the specification.) Figure 1The given structural diagram shows a portion of the component for detailed explanation. The support rail 1 is made of aluminum alloy and comprises a main support portion 101 and a hanging rail portion 102. The drive chain 3 is parallel to the support rail 1 and positioned near the hanging rail portion 102. The lateral hanger 2 has protruding rod-like sections extending laterally for hanging finished garments or individual pieces of fabric. A pair of traveling rollers 201, arranged vertically on the upper and lower sides, are installed on the side of the lateral hanger 2 closest to the support rail 1.

[0032] For details, please refer to the instruction manual appendix. Figure 3 The cross-sectional structural diagram shown indicates that two traveling rollers 201 are specifically selected. These two traveling rollers 201 are arranged on the upper and lower sides of the mounting rail 102, respectively. An elastic material layer 4, such as silicone or resin, with a certain elastic deformation capability, is provided between the surface of the traveling roller 201 and the mounting rail 102. Simultaneously, a connecting piece is installed on the lateral mounting frame 2 at the middle position of the two traveling rollers 201. This connecting piece extends outward and is connected and fixed to a link on the drive chain 3. To ensure a more balanced pulling force provided by the chain link to the lateral mounting frame 2 during its forward movement, this embodiment employs a structural design where the drive chain 3 passes horizontally through the area between the axles of the upper and lower traveling rollers 201. When a single chain link pulls and pushes the side mounting frame 2 carrying the material forward, it can transmit the pushing force to the upper and lower rotating rollers more evenly, thereby preventing the side mounting frame 2 from deflecting or overturning forward or backward in the plane formed by the two rotating rollers, and improving the stability of the side mounting frame 2 and the material during the movement.

[0033] In this structure, when a portion of the drive chain 3 is arranged around a drive gear located at the end of the support guide rail 1, and the center of the drive gear is fixedly connected to the output shaft of the drive motor, starting the drive motor will cause the entire drive chain 3 to rotate. Simultaneously, each lateral mounting bracket 2, fixedly connected to a single link on the drive chain 3, can be continuously pushed forward along the extension direction of the guide rail, thereby pushing the material placed on the lateral mounting bracket 2 forward to the target area. During this process, the presence of an elastic material layer 4 between the traveling rollers 201 located on the upper and lower sides of the mounting guide rail 102 and the mounting guide rail 102 effectively reduces the vibration and impact between the two components, and also effectively reduces the entry of debris and dust generated by wear into the drive chain 3 and the material below, improving the overall stability and cleanliness of the equipment system.

[0034] To improve the connection stability between the traveling roller 201 and the mounting rail 102, please refer to the attached instruction manual. Figure 3 The structure shown features an annular recessed fitting groove 2011 on the outer periphery of the traveling roller 201, while the mounting guide rail 102 has protruding fitting ends 1021 at its upper and lower ends. These protruding fitting ends 1021 can be respectively inserted into the recessed fitting grooves 2011 on the two traveling rollers 201 arranged in the upper and lower layers, achieving a positioning connection between the components. At this time, the mutual abutment between the protruding fitting section and the sidewall of the recessed fitting groove 2011 ensures the lateral balance and stability of the traveling roller 201 during its rolling motion. Furthermore, to improve the ease of installation and connection of the two components, the edge of the projection of the protruding fitting end 1021 onto the vertical plane can be arc-shaped, and the edge of the cross-sectional shape of the recessed fitting groove 2011 can also be an arc-shaped shape corresponding to the protruding fitting end 1021.

[0035] Furthermore, since the elastic material layer 4 is generally made of rubber or silicone, it will undergo a certain degree of irreversible plastic deformation under prolonged pressure. This can easily cause gaps between the mounting guide rails 102 on both sides of the elastic material layer 4 and the traveling rollers 201, leading to wobbling of the traveling rollers 201 during rotation and affecting the stability of material transfer and conveying. Considering this problem, the elastic material layer 4 needs to be replaced and adjusted periodically. Therefore, when installing the elastic material layer 4 structure, it is necessary to ensure a firm connection during the normal rotation and movement of the traveling rollers 201, preventing loosening and detachment, while also allowing for easy disassembly and replacement when needed.

[0036] Therefore, in this embodiment, please refer to the appendix to the specification. Figure 4The provided enlarged structural diagram shows a structure in which an elastic material layer 4 is arranged around and covers the outer side of the mounting guide section 102. One end of the elastic material layer 4 is fixed to the support guide 1 via a snap-fit ​​connection, while the other end is locked to the support guide 1 via bolts 5. Furthermore, to improve the stability of the connection between the elastic material layer 4 and the mounting guide section 102, multiple snap-fit ​​connection structures 6 can be provided between the elastic material layer 4 and the various mounting guide sections 102. Specifically, the snap-fit ​​connection structure 6 includes a dovetail-shaped groove 601 formed on the outer side of the mounting guide section 102, and a dovetail-shaped snap-fit ​​portion 602 formed on the inner side of the elastic material layer 4. In this structural configuration, during installation and fixing, the dovetail-shaped engaging parts 602, as part of the elastic material layer 4, possess a certain elastic deformation capability. Using a specialized clamping tool, a relatively large force is applied to press the dovetail-shaped engaging parts 602 into the dovetail-shaped slots 601, thus forming the engaging connection structure 6. The weight of the side-mounted frame 2 and the material below its load acts on the surface of the elastic material layer 4 through the surfaces of the two traveling rollers 201. Further analysis reveals that the traction and torsional forces exerted on the elastic material layer 4 by the inner arc-shaped walls of the traveling rollers 201 directly pull the aforementioned dovetail-shaped engaging parts 602 out of the dovetail-shaped slots 601 using lateral force. Since this force is not in the same direction as when the two parts are engaged or disengaged, a lateral force far exceeding that applied in the direct-direction state is required to disengage the two parts, thus significantly improving the load-bearing capacity and durability of the conveying assembly during operation.

[0037] Of course, considering that when performing partial replacement and repair of the elastic material layer 4, it is necessary to avoid affecting other normal parts as much as possible, in this embodiment, it is also possible to consider adopting a segmented structure for the elastic material layer 4 that covers and surrounds the outside of the hanging guide rail 102.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
