Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to an adjustable garment conveying and loading device. Background Technology

[0002] The garment hanging assembly line mainly includes a main rail, a transmission mechanism, and several workstations. The workstations are connected to the main rail via an inlet mechanism and a lifting mechanism. The garments hanging on the main rail are pushed by push rods on the transmission mechanism, which are driven by a transmission chain. The transmission chain is driven by a main motor through a sprocket. For example, patent number 201620836768.7 discloses an intermittent transmission garment hanging assembly line with an inlet mechanism, including a lifting arm and a descending guide rail. A workstation is set in the middle of the descending guide rail. The inlet end of the workstation is connected to the descending guide rail via an inlet mechanism, and the outlet end of the workstation is connected to the descending guide rail via a lifting arm.

[0003] Its drawback is the intermittent transmission impact problem. The drawback manifests as follows: when using traditional ratchet and pawl or incomplete gear mechanisms to achieve intermittent transmission, a rigid impact is generated at the moment of start and stop, resulting in: chain tension fluctuation of ±25% (actual data), hanger clamping and positioning error of ±1.2mm (exceeding the industry standard of ±0.5mm), and a 40% reduction in the lifespan of key components (sprockets, bearings). Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable garment conveying and hanging loading device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable garment conveying and hanging loading device, comprising: a frame, a loader main box mounted on the frame, a sprocket mounted on the loader main box, a chain wound around the sprocket, wherein the loader main box drives the sprocket and the chain to run synchronously, and an adjustable hanger guide strip is arranged on the loader main box along the hanger's path, wherein the sprocket and the chain form a transmission pair and cooperate with the hanger guide strip to automatically engage and position the hanger wheel with the chain.

[0006] As a preferred embodiment of this application, the hanger guide bar includes: a mounting main board, an elastic arm, an adjusting screw, and a nut; the elastic arm forms a fixed fulcrum with a pre-installed movable nut, and the adjusting screw passes through the nut to form a threaded pair with the elastic arm; when the adjusting screw is rotated, its axial displacement is converted into a pushing force on the elastic arm through the thread rotation, causing the elastic arm to generate an angular displacement around the connection point, thereby changing the radial clearance between the front guide surface of the elastic arm and the outer edge of the sprocket disc to achieve stepless adjustment.

[0007] As a preferred embodiment of this application, the loader main box adopts a double-layer stacked structure, the top layer of which is used to install the motor fixing plate of the sprocket disc, the bottom surface of the motor fixing plate is a base plate, and the clothes hanger guide strip is fixed on the base plate.

[0008] As a preferred embodiment of this application, the positioning holes on the motor mounting plate and the mounting motherboard mounting holes on the base plate are clamped together in one operation, and the horizontal distance remains unchanged.

[0009] As a preferred embodiment of this application, the elastic arm and the mounting motherboard are integrally bent structures, and the free end of the elastic arm is provided with a guide slope, which forms a hanger wheel guide trajectory with the notch on the outer edge of the chain.

[0010] As a preferred embodiment of this application, the loader main box is connected to the frame by bolts, and the bolts are clearance-fitted with the positioning holes of the frame.

[0011] As a preferred embodiment of this application, the teeth of the chain notch have an involute profile, forming a line contact transmission with the rim of the hanger wheel.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: The reliability of automatic engagement is enhanced.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Garment hanging production lines, widely used in garment manufacturing enterprises, generally employ two methods to lift hangers from a low point to a high point. The most common method is the aluminum arm belt drive mechanism, suitable for lifting hangers with a height difference of up to 2 meters. For hangers with larger height differences, a chain lifting mechanism is typically used. This mechanism is powered by a loader, driving a specially designed chain 5. The hanger wheels 4 are loaded into slots 51 on the chain 5, and the chain 5 lifts the hanger from the low point to the high point. A release mechanism then releases the hanger wheels 4 from the slots 51. Some loader units on the market are either complex and expensive or have unstable performance, easily leading to operational failures. This application, considering operational characteristics, utilizes a modular structure design and simple adjustable guide bars to significantly reduce manufacturing costs, facilitating widespread use in garment hanging production lines and serving end customers. Specifically, it is an adjustable garment conveying and loading device, such as... Figure 1-6 The device includes: a frame 6, a loader main housing 1 mounted on the frame 6, a sprocket disc 3 mounted on the loader main housing 1, and a chain 5 wound around the sprocket disc 3. The loader main housing 1 drives the sprocket disc 3 and the chain 5 to run synchronously. An adjustable hanger guide bar 2 is arranged on the loader main housing 1 along the hanger's path. The sprocket disc 3 and the chain 5 form a transmission pair, and the hanger guide bar 2 allows the hanger wheels 4 to automatically engage and position with the chain 5. In this application, the frame 6 serves as the supporting foundation for the entire device. The loader main housing 1 is mounted on the frame 6, the sprocket disc 3 is mounted on the loader main housing 1, and the chain 5 is wound around the sprocket disc 3. The loader main housing 1 drives the sprocket disc 3 to rotate, thereby driving the chain 5 to run synchronously. The hanger guide bar 2 is arranged along the hanger's path and is adjustable. The sprocket 3 and the chain 5 form a transmission pair, which, together with the hanger guide strip 2, enables the hanger wheel 4 and the chain 5 to automatically engage and position, thus achieving stable transmission of the hanger.

[0017] Through the transmission and cooperation of the sprocket disc 3 and chain 5 with the hanger guide strip 2, the hanger is automatically snapped and positioned, ensuring the stability and accuracy of the hanger during transmission and improving the efficiency and reliability of garment transmission. The frame 6 can be constructed using common industrial profiles, such as aluminum alloy profiles, which are lightweight, high-strength, and easy to process and assemble. The sprocket disc 3 can be a standard industrial sprocket, such as a sprocket with the model number "40.00.100". Its tooth count, pitch, and other parameters can be selected according to the actual chain 5 specifications and transmission requirements. The chain 5 can be a standard transmission chain, such as a chain with the model number "40A", which has good wear resistance and transmission performance (and the loader's main box 1 has a motor on its back; since this is existing technology and easy to understand, it will not be described in detail and will be illustrated in a separate diagram).

[0018] In actual operation, the hanger guide bar 2 includes: a mounting main board 21, an elastic arm 22, an adjusting screw 23, and a nut 24. The elastic arm 22 forms a fixed fulcrum with the pre-installed movable nut 24. The adjusting screw 23 passes through the nut 24 and forms a threaded pair with the elastic arm 22. When the adjusting screw 23 is rotated, its axial displacement is converted into a pushing force on the elastic arm 22 through the thread rotation, causing the elastic arm 22 to generate angular displacement around the connection point. This changes the radial gap between the front guide surface of the elastic arm 22 and the outer edge of the sprocket disk 3, achieving stepless adjustment. Through the cooperation of the adjusting screw 23 and the elastic arm 22, the stepless adjustment function of the hanger guide bar 2 is realized. The guide gap can be flexibly adjusted according to hangers of different sizes and shapes, improving the versatility and adaptability of the device and better meeting the needs of various garment conveying.

[0019] To facilitate more rational installation of various components and simplify assembly and maintenance, the loader main housing 1 adopts a double-layer stacked structure. The top layer houses the motor mounting plate 11 for the sprocket disc 3, and the bottom surface of the motor mounting plate 11 is a base plate 12. The clothes hanger guide strip 2 is fixed to the base plate 12. This double-layer stacked structure makes the device more compact and improves space utilization. Simultaneously, fixing the clothes hanger guide strip 2 to the base plate 12 ensures the stability of the guide strip installation and improves the overall performance of the device. This structure also enhances the motor vibration suppression effect.

[0020] The positioning holes on the motor mounting plate 11 and the mounting main plate 21 on the base plate 12 are clamped together in one operation, and the horizontal distance remains unchanged. This one-time clamping process ensures the high precision of the positioning holes and the mounting holes, improves the installation accuracy and stability between the motor mounting plate 11 and the base plate 12, thereby ensuring the operating accuracy and reliability of the entire device and reducing malfunctions and errors caused by installation errors.

[0021] The elastic arm 22 and the mounting plate 21 are integrally bent structures. The free end of the elastic arm 22 is provided with a guide slope. The guide slope and the notch 51 on the outer edge of the chain 5 (specifically located at the outer edge of the sprocket disc 3) form the guide trajectory for the hanger wheel 4. The integral bent structure improves the connection strength and reliability between the elastic arm 22 and the mounting plate 21, reduces assembly steps, and lowers production costs. The design of the guide slope allows the hanger wheel 4 to enter the notch 51 of the chain 5 more smoothly, improving the transmission efficiency and stability of the hanger.

[0022] The loader main box 1 is connected to the frame 6 by bolts. The bolts are fitted with the positioning holes of the frame 6 with clearance, which quickly realizes the connection and positioning of the loader main box 1 and the frame 6, thus improving production efficiency.

[0023] The teeth of the notch 51 in the chain 5 have an involute profile, forming line contact transmission with the rim of the hanger wheel 4. The involute tooth profile provides good meshing performance and smooth transmission, reducing vibration and noise during transmission and improving the service life of the device. The line contact transmission method makes the contact stress distribution between the chain 5 and the hanger wheel 4 more uniform, further improving the stability and reliability of the transmission.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
