Description

Technical Field

[0001] This invention relates to the field of hose coiling equipment technology, specifically to an automatic coil-changing hose coiling device. Background Technology

[0002] Hoses are important components in modern industry. They are mainly used as protective conduits for wires and cables, signal wires and cables of automated instruments, and shower hoses for civilian use. Hoses are mainly classified by material as: stainless steel hoses, metal hoses, corrugated hoses, rubber hoses, and plastic hoses.

[0003] In the production, processing, and storage of hoses, after being formed on the production line, the hoses are coiled to meet the needs of customers, processing procedures, or storage space. Depending on the type of hose, different weights and lengths of coils are produced. Currently, there are two main methods of coiling: one is manual coiling, where the hose is manually wound around a mold layer by layer. After a single layer is wound, the process is repeated for the second, third, and so on up to the Nth layer. The hose is manually coiled from the inside out in the first layer to the outermost coil, then the second layer is stacked and coiled from the outermost coil to the innermost coil, and so on, until the specified length is reached. At this point, the hose is fully wound around the mold, and then a demolding process is performed to separate the hose coil from the mold. The first method of coiling hoses is extremely inefficient and labor-intensive because it is entirely manual. Prolonged work can lead to worker fatigue, resulting in frequent instances of loose or misaligned hose coils. Furthermore, misoperation often causes premature or delayed hose breakage, resulting in a coil length that is either less than or greater than the intended length. The second method is a hose coiling machine. Existing coiling devices typically include a base frame, baffles, and support components. The base frame and baffles form a semi-enclosed structure, providing storage space for coiled hoses. The support components include two discs and a connecting shaft, used to coil the hoses sequentially around the connecting shaft. During use, the outermost end is pulled up; after use, the hose is coiled into a single coil.

[0004] In the manufacturing of rubber hoses, vulcanization is the final and one of the main processes. It's crucial for achieving high bonding strength between the rubber and the reinforcing layer, ensuring they form a cohesive whole. This process is also essential for guaranteeing and improving product quality. Currently, disc vulcanization is commonly used in rubber hose production. Before vulcanization, the hose needs to be coiled. Workers lift the turntable, filled with manually coiled or machine-filled hose, onto the vulcanization rack for further processing. During vulcanization, the turntable needs to be removed for the next coiling cycle. Therefore, manual coiling requires... The vulcanization method is extremely labor-intensive, and the process of changing the discs is time-consuming and laborious, which cannot meet the needs of high-speed production and has low production efficiency. As for the double-turntable coiling machine, the device requires a large space and usually has two turntable positions. After one turntable is full of tubing, it is rotated to the other side by the central rotating mechanism. The empty turntable on the other side is rotated to the coiling production position to continue coiling. Therefore, the device works with the workers to disassemble the full turntable and install the empty turntable, alternating to improve time utilization and thus improve work efficiency. However, the position changing is manually controlled by a cylinder, which is prone to overshoot and cannot accurately position.

[0005] In a flexible hose planar stacking coiling machine with publication number CN113307097B, the device uses a single turntable for coiling and is equipped with a roller mechanism to calculate the length of each hose, control the size of the coil, and prevent the hose from shaking during coiling, thus fixing the hose. However, after the first turntable of the device finishes coiling, the operator needs to disassemble the coil before coiling can be done again. This results in the device being unable to work when disassembling the coil, leading to low time utilization and low production efficiency.

[0006] In a coiling device for hoses disclosed in CN110950188A, the device adopts a vertical double-disc rod winding structure, which saves space compared to the horizontal double-disc type and solves the problem of easy confusion when coiling double-disc coiling machines. However, similar to the single-disc coiling machine, the device needs to be removed after coiling before it can work again. Furthermore, due to the use of rods for coiling, the coils are difficult to remove. Therefore, this device is only suitable for finished hoses. Summary of the Invention

[0007] This invention provides an automatic disc-changing hose coiling device, which solves the problem in the prior art where a single-disc coiling device requires workers to disassemble the coil after completing its work before it can be coiled again. This results in the device being unable to work while disassembling the coil, leading to low time utilization and low production efficiency.

[0008] To address the aforementioned problems, this invention provides an automatic reel-changing hose coil device that, compared to existing technologies, features a simple structure, small footprint, rapid and accurate repositioning, and efficient continuous production.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An automatic reel-changing hose coiling device includes: a main frame, which is a rectangular frame structure composed of several longitudinal beams; two parallel linear rails are provided at the top of the main frame, perpendicular to and fixed to the longitudinal beams; two symmetrical bottom crossbeams are provided at the middle of the bottom of the main frame, parallel to the linear rails, and a cylinder fixing bracket is provided at one end of each bottom crossbeam; the cylinder fixing bracket connects a lifting cylinder and a working disc rotating cylinder; the other end of the working disc rotating cylinder is connected to a turntable connecting shaft, which fixes the center of the working disc; two symmetrical middle crossbeams are also provided between the bottom crossbeams and the linear rails; the middle crossbeams are positioned away from the cylinder fixing brackets. One end is provided with a notch plate, on which symmetrical double telescopic cylinders are fixed. The cylinder rods of the double telescopic cylinders are fixed to the work plate. The two turntables of this invention are the work plate and the work plate. During operation, the working plate rotation cylinder drives the working plate to rotate and coil the tube, while the work plate is in a standby state and does not affect the normal operation of the working plate. The linear guide is two linear guide rails located on both sides of the upper part of the main frame. After the working plate has finished coiling the tube, the working plate can move along the linear guide to the work plate turntable to replace the work plate. After the tube is disassembled, it waits for the next operation.

[0011] Preferably, the cylinder mounting bracket has an L-shaped cross-section. The base plate fixes the lifting cylinder, and the side plate fixes the working disc rotating cylinder. The lifting cylinder and the working disc rotating cylinder are coaxially mounted. The turntable connecting shaft is fixed to a rectangular upper panel. Both sides of the upper panel contact two linear rails, and linear rail sliders are provided on both sides of the upper panel and mounted on the same-side linear rails, allowing the upper panel to slide along the linear rails. When the working disc is ready to work, the lifting cylinder is used to raise the working disc rotating cylinder connected to it, thereby fixing the output shaft of the working disc rotating cylinder to the center position of the working disc, thus causing the working disc to rotate into the working disc. In the working state, after the work is completed, the lifting cylinder drives the working plate rotation cylinder to lower and disconnect from the working plate, thereby moving the working plate along the rail to the waiting state. This method of starting and stopping the working state is completed by the lifting cylinder and the working plate rotation cylinder, so there is no need for a complex electrical control system, which reduces the overall production cost and the operating threshold of the equipment. The upper panel is used to support the working plate, and the upper panel slides in contact with the rail. After the working plate finishes working, it is used to support the working plate to move to the waiting plate area, so that the workers or the gripping mechanism can unload the coil and wait for the next coil.

[0012] Preferably, the distance between the middle crossbeams is greater than that between the two bottom crossbeams, and four inner sprockets are provided on the outer sides of both ends of the bottom middle beam. Chains are installed on the two sprockets on the same side. The recessed plate is located on the upper part of the middle crossbeam away from the cylinder fixing frame. Chain fixing blocks are provided on both sides of the recessed plate parallel to the middle crossbeam and are fixed to the chain on the same side, so that the recessed plate can slide along the direction of chain movement. The inner sprockets and the chain constitute a transmission mechanism, and the chain fixing blocks provided on the recessed plate are fixed to the chain provided on the inner sprocket on the same side, so that the recessed plate can rotate with the inner sprocket, thereby driving the chain to move, so that the recessed plate can move parallel along the chain. The sprocket-chain transmission method has low cost and high transmission efficiency, and is widely applicable. By moving the recessed plate through the sprocket-chain, the work plate provided on the upper part of the recessed plate can move to the work plate area, thereby basically realizing the working principle of the present invention.

[0013] Preferably, the lower part of the longitudinal beams at both ends of the main frame on the same side as the linear guide is provided with an outer sprocket, and a chain is installed on the two outer sprockets on the same side. A chain connecting plate is also provided at the bottom of the upper plate on the same side as the linear guide. The chain connecting plate is installed on the bottom surface of the lower panel, with one end connected to the lower panel and the other end fixed to the chain between the two outer sprockets on the same side. After the working disc finishes one coiling operation, the linear guide is used to carry the working disc to move along the linear guide to the area of ​​the working disc to be worked. The outer sprockets are located on the main frame below the linear guide. The outer sprockets and the chain form a transmission mechanism and are connected by the chain connecting plate. One end is fixed to the upper panel, and the other end is fixed to the lower end of the chain of the outer sprocket on the same side. Thus, when the upper panel moves along the rail, it can drive the outer sprocket-chain transmission mechanism below the rail to move. Moreover, the moving direction of the upper panel is opposite to the moving direction of the outer sprocket. The chain connecting plate can complete the linkage effect between the rail and the outer sprocket-chain transmission mechanism with opposite moving directions. It does not require a complex feedback circuit system control, which reduces the overall production cost and operation threshold of the device.

[0014] Preferably, the bottom of the chain fixing plate is fixed to the lower part of the chain between the two outer sprockets on the same side. The rotation direction of the outer sprockets is opposite to the sliding direction of the upper panel. A sprocket drive rod is provided between the closest outer sprocket and inner sprocket on the same side. A connecting rod is provided between the two symmetrical inner sprockets. The sprocket drive rod and the connecting rod on the same side are integrally formed. The sprocket drive rod connects the outer sprocket and inner sprocket on the same side, while the connecting rod connects the inner sprocket on the opposite side. This connects the upper panel-rail to the inner sprocket-chain and the outer sprocket-chain transmission mechanism. When the upper panel moves, it drives the outer sprocket-chain, which in turn drives the inner sprocket-chain, causing the recessed plate to move in the opposite direction to the upper panel. Therefore, the transmission mechanism of this invention relies on the transmission mechanism of sprocket-chain, drive rod, and connecting rod to achieve transmission. It does not require multiple motors to input into each transmission mechanism and a complex feedback circuit system, thus making this invention have lower production and maintenance costs.

[0015] Preferably, the notched plate has a notch on one side near the working disc rotating cylinder, the size and shape of the notch matching the working disc rotating cylinder, and the notched plate also has four evenly distributed support columns, the tops of the support columns and the cylinder rod are fixed to a rectangular floating plate, and the working disc is fixed on the floating plate.

[0016] Preferably, the system also includes a slide module. A sliding plate is fixed to one end of the linear guide near the working disc. The sliding plate connects the two linear guides and has a screw. A sleeve is fitted onto the screw and can slide along the screw. A hose input module is also slidably fixed on the outer periphery of the sleeve. The slide module is installed on the two linear guides near the working disc and does not affect the free sliding of the upper panel on the linear guides. The slide module cooperates with the hose input module to accommodate hoses input at different angles, reducing the placement requirements of the invention during operation.

[0017] Preferably, the hose input module includes a sliding base, which is slidably fixed on the outer periphery of the sleeve and can slide along the sleeve. The sliding base is provided with a double roller mechanism, and the bottom of the double roller mechanism is provided with an extension plate extending away from the working plate along the double roller mechanism. The end of the extension plate away from the working plate is provided with a guide cylinder perpendicular to the extension plate. The hose input module guides and restricts the hose that is input into the working plate, reducing the problem of easy confusion when coiling.

[0018] Preferably, the working disc and the disc to be worked on are the same. The working disc has a circular disc structure. The outer periphery of the working disc is provided with an annular outer working ring wall that extends outward perpendicular to the working disc. The working disc is also provided with an annular inner working ring wall that is concentrically arranged. The inner working ring wall extends outward perpendicular to the working disc. The center of the inner working ring wall is fixed to the turntable connecting shaft.

[0019] Preferably, the ends of the two crossbeams are connected and fixed by connecting rods, and the connecting rods are equipped with hydraulic dampers. The hydraulic dampers are used to buffer the movement of the notched plate along the chain direction of the outer sprocket on the same side, so as to prevent the notched plate from hitting the main frame or rushing out of the main frame when it moves, thereby improving safety and practicality.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention adopts a frame-type main structure, with sprocket-chain as the main transmission method and plate as the main parts. The overall structure is relatively simple. The overall device size can be designed according to the size of the coil. Moreover, this device is mainly mechanical and only has a single motor input, resulting in low production and maintenance costs. It does not require multiple motor inputs or complex circuit control systems, resulting in low overall cost, low operating threshold, and wide applicability.

[0022] The upper panel-rail is fully connected to the transmission mechanisms of the inner sprocket-chain and the outer sprocket-chain in this invention, so that no impact occurs when the working disc and the work disc are moving alternately, and the repositioning is accurate. The hydraulic buffers at both ends of the two crossbeams prevent the concave plate from hitting the main frame and causing the upper panel to detach from the rail, thus improving safety and operability.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 This embodiment describes an automatic reel-changing hose coil device, comprising a main frame 3, which is a rectangular frame structure composed of several longitudinal beams 3.2. The top of the main frame 3 is provided with two parallel linear rails 3.1, which are perpendicular to and fixed to the longitudinal beams. The middle of the bottom of the main frame is provided with two symmetrical bottom crossbeams 3.4 parallel to the linear rails, and one end of the two bottom crossbeams is provided with a cylinder fixing bracket 11. The cylinder fixing bracket connects a lifting cylinder 9 and a working disc rotating cylinder 10. The other end of the working disc rotating cylinder is connected to a turntable connecting shaft 24, which fixes the center of the working disc. Two symmetrical middle crossbeams 3.3 are also provided between the bottom crossbeams and the linear rails. The end of the middle crossbeam away from the cylinder fixing bracket is provided with a recessed plate 15. Symmetrical double telescopic cylinders 12 are fixed on the recessed plate, and the cylinder rods 17 of the double telescopic cylinders are fixed to the working disc. In this embodiment, the two turntables are a working turntable and a working turntable. During operation, the working turntable is rotated by a rotary cylinder to perform coiling, while the working turntable is in a standby state and does not affect the normal operation of the working turntable. The linear guides are two linear guides located on both sides of the upper part of the main frame. After the working turntable finishes coiling, the working turntable can move along the linear guides to the working turntable to replace the working turntable. After the coiling is disassembled, it waits for the next operation.

[0030] The cylinder mounting bracket 11 has an L-shaped cross section. The base plate fixes the lifting cylinder 9, and the side plate fixes the working plate rotating cylinder 10. The lifting cylinder and the working plate rotating cylinder are coaxially installed. The turntable connecting shaft is fixed to the rectangular upper panel 18. The two sides of the upper panel are in contact with the two linear rails 3.1, and the upper panel has linear rail sliders on both sides installed on the same side linear rail, so that the upper panel can slide along the linear rail. When the working disc is ready to work, the lifting cylinder raises the working disc rotating cylinder connected to the lifting cylinder, thereby fixing the output shaft of the working disc rotating cylinder to the center position of the working disc, and causing the working disc to rotate and enter the working state. After the work is completed, the lifting cylinder drives the working disc rotating cylinder to lower and disconnects from the working disc, thereby moving the working disc along the rail to the waiting state. This method of starting and stopping the working state is completed by the lifting cylinder and the working disc rotating cylinder, so there is no need for a complex electrical control system, thereby reducing the overall production cost and operating threshold of the equipment. The upper panel is used to support the working disc, and the upper panel slides in contact with the rail. After the working disc finishes working, it is used to support the working disc to move to the waiting area, so that the workers or the gripping mechanism can unload the coil and wait for the next coil.

[0031] The distance between the middle crossbeams 3.3 is greater than that between the two bottom crossbeams 3.4, and four inner sprockets 7 are provided on the outer sides of both ends of the middle crossbeam. Chains 5 are installed on the two sprockets on the same side. The recessed plate 15 is located on the upper part of the middle crossbeam away from the cylinder fixing frame. Chain fixing blocks 23 are provided on both sides of the recessed plate parallel to the middle crossbeam and are fixed to the chain on the same side, so that the recessed plate can slide along the direction of chain movement. The inner sprockets and chains constitute a transmission mechanism, and the chain fixing blocks provided on the recessed plate are fixed to the chain provided on the inner sprocket on the same side, so that the recessed plate can rotate with the inner sprocket, thereby driving the chain to move, so that the recessed plate can move parallel along the chain. The sprocket-chain transmission method has low cost and high transmission efficiency, and is widely applicable. By moving the recessed plate through the sprocket-chain, the work plate provided on the upper part of the recessed plate can move to the work plate area, thereby basically realizing the working principle of the present invention.

[0032] On the main frame 3, at the lower part of the longitudinal beams 3.2 on the same side as the linear guide 3.1, there is an outer sprocket 6, and chains are installed on the two outer sprockets on the same side. A chain connecting plate 13 is also provided at the bottom of the upper plate on the same side as the linear guide. The chain connecting plate is installed on the bottom surface of the upper panel 18, with one end connected to the upper panel and the other end fixed to the chain between the two outer sprockets on the same side. After the working disc finishes one coiling operation, the linear guide is used to carry the working disc to the area to be worked on. The outer sprockets are located on the main frame below the linear guide. The outer sprockets and chains form a transmission mechanism, connected by the chain connecting plate. One end is fixed to the upper panel, and the other end is fixed to the lower end of the chain of the outer sprocket on the same side. Thus, when the upper panel moves along the rail, it can drive the outer sprocket-chain transmission mechanism below the rail to move. Moreover, the moving direction of the upper panel is opposite to the moving direction of the outer sprocket. The chain connecting plate can complete the linkage effect between the rail and the outer sprocket-chain transmission mechanism with opposite moving directions. It does not require a complex feedback circuit system control, which reduces the overall production cost and operation threshold of the device.

[0033] The bottom of the chain connecting plate 13 is fixed to the lower part of the chain between the two outer sprockets on the same side. The rotation direction of the outer sprocket 6 is opposite to the sliding direction of the upper panel. A sprocket drive rod 19 is provided between the closest outer sprocket and inner sprocket on the same side, and a connecting rod 20 is provided between the two symmetrical inner sprockets. The sprocket drive rod and the connecting rod on the same side are integrally formed. The sprocket drive rod connects the outer sprocket and inner sprocket on the same side, while the connecting rod connects the inner sprocket on the opposite side. This connects the upper panel-rail to the inner sprocket-chain and outer sprocket-chain transmission mechanisms. When the upper panel moves, it drives the outer sprocket-chain, which in turn drives the inner sprocket-chain, causing the recessed plate to move in the opposite direction to the upper panel. Therefore, the transmission mechanism of this invention relies on the transmission mechanism of the sprocket-chain, drive rod, and connecting rod to achieve transmission. It does not require multiple motors to input into each transmission mechanism and a complex feedback circuit system, thus making this invention have lower production and maintenance costs.

[0034] The notched plate 15 has a notch on one side near the working disc rotating cylinder 10. The size and shape of the notch match the working disc rotating cylinder. The notched plate also has four evenly distributed support columns 16. The tops of the support columns and cylinder rods are fixed to a rectangular floating plate 25. The working disc 1 is fixed on the floating plate. Since the positions of the lifting cylinder and the working disc rotating cylinder on the middle crossbeam are fixed relative to the sliding upper panel or the notched plate, when the working disc finishes its work, it moves along the rail and drives the notched plate to move towards the working disc rotating cylinder. When the notched plate moves to the working disc rotating cylinder and the working disc is located directly above the working disc rotating cylinder, the notched plate completes its movement. Therefore, the notch on the notched plate must be able to accommodate the working disc rotating cylinder to the center of the notched plate so that the working disc can move directly above the working disc rotating cylinder.

[0035] It also includes a slide module 4, with a sliding plate 4.3 fixed to one end of the linear rails near the working plate 2. The sliding plate connects the two linear rails 3.1, and a screw 4.1 is provided on the sliding plate. A sleeve 4.2 is fitted on the screw, and the sleeve can slide along the screw. A hose input module 14 is also slidably fixed on the outer periphery of the sleeve. The slide module is installed on the two linear rails near the working plate and does not affect the free sliding of the upper panel on the linear rails. The slide module cooperates with the hose input module to accommodate hoses input at different angles, reducing the placement requirements of the invention during operation.

[0036] The hose input module 14 includes a sliding base 14.5, which is slidably fixed on the outer periphery of the sleeve and can slide along the sleeve. A double-roller mechanism 14.1 is provided on the sliding base. An extension plate 14.2 extends from the bottom of the double-roller mechanism away from the working disc. A guide cylinder 14.3 perpendicular to the extension plate is provided at the end of the extension plate away from the working disc. The guide cylinder consists of two symmetrical vertical shaft cylinders, with the hose passing between them for guidance. Furthermore, a sliding cylinder 14.4 is also provided on the extension plate between the two vertical shaft cylinders. The rotation axis of the sliding cylinder is parallel to the extension plate. The horizontally positioned section on the extension plate, not between it and the guide drum, serves to guide the coil and reduce friction to increase coiling speed. The hose input module guides and restricts the hose being input into the working disc, reducing the likelihood of coiling confusion. The double-roller mechanism also integrates a counting sensor to calculate the length of the input hose, which, in conjunction with the automatic cutting device, cuts the hose to the rated length. In addition, the sliding base can be connected to a motor, allowing it to work in conjunction with the counting sensor. When the hose is coiled into the working disc, the sliding base moves along the sleeve towards the edge of the working disc according to the coil radius, facilitating coiling.

[0037] The working disc 2 is the same as the working disc 1. The working disc has a circular disc structure. The outer periphery of the working disc is provided with an annular outer working ring wall 2.2 that extends outward perpendicularly to the working disc. The working disc is also provided with an annular inner working ring wall 2.1 that is concentrically arranged. The inner working ring wall extends outward perpendicularly to the working disc. The center of the inner working ring wall is fixed to the turntable connecting shaft 24.

[0038] The ends of the two crossbeams are connected and fixed by connecting rods, and hydraulic buffers 21 are installed on the connecting rods. The hydraulic buffers are used to buffer the movement of the notched plate along the chain direction of the outer sprocket on the same side, so as to prevent the notched plate from hitting the main frame or rushing out of the main frame when it moves, thereby improving safety and practicality.

[0039] In addition, the disc-changing drive motor 8 in this embodiment is located at the bottom of the main frame 3, near the bottom of one end of the sprocket drive rod 19. The disc-changing drive motor gear meshes with one of the sprocket drive rod gears, thereby enabling the transmission mechanism to access power. It is only necessary to control the drive motor to rotate forward and backward. For safety considerations, distance sensors and feedback circuits can be added to both ends of the middle crossbeam so that the motor can be stopped suddenly when it moves near the main frame.

[0040] The workflow of this embodiment is as follows:

[0041] After installing the working disc and the work tray, connect the power. The hose enters the working disc through the hose input module, and initially, the hose head must be fixed to the inner wall of the working disc. Then, start the working disc rotating cylinder to coil the hose. During coiling, the sensors designed on the double roller mechanism will move the sliding base from near the center of the working disc along the sleeve towards the edge of the working disc according to the hose input length, allowing the hose to be smoothly coiled into the working disc. After one coiling cycle, the hose is cut off with the addition of an automatic cutting device. The sliding base moves back to near the center of the working disc along the sleeve. The drive motor drives the working disc to move along the guide rail towards the work tray. The concave plate where the work tray is located is also driven by the drive motor to move towards the working disc rotating cylinder. At the same time, the double telescopic air... The cylinder lowers the cylinder rod so that the work plate is lower than the working plate to avoid collision. When the working plate rotating cylinder is located at the center of the notch in the notch plate, the work plate is directly above the working plate rotating cylinder. At this time, the lifting cylinder raises the working plate rotating cylinder to connect with the work plate. At the same time, the working plate and the work plate have been interchanged. When the operator removes the coil of the working plate, it does not affect the coiling work of the work plate. Therefore, this embodiment has the effect of efficient continuous production. After the work plate has finished working, similarly, the work plate is disconnected from the working plate rotating cylinder, and the work plate double telescopic cylinder is lowered to be lower than the working plate. The working plate and the work plate can then be interchanged again, thereby achieving the effect of continuous production without stopping the machine.

[0042] The above are merely preferred embodiments of this invention and do not constitute any limitation on the present invention. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the technical solution of the invention.
