Description

Technical Field

[0001] This invention relates to the field of scraper conveyor technology, and more specifically, to a circular ring chain swing conveyor. Background Technology

[0002] Circular link chains, as core components of scraper conveyors, play a crucial role in power transmission and material transport. The production process of circular link chains can be summarized as follows: material preparation, chain weaving and joining, welding, primary stretching, heat treatment, secondary stretching, inspection, and testing. During the production of circular link chains, due to their long length, skewed pulling during hoisting is extremely common, posing safety hazards. Hoisting the chain often requires bending it several times, frequently resulting in chain stacking and requiring multiple hoisting and placement operations. This leads to significant wasted effort. Furthermore, the non-standard chain shape results in a messy production site, with chains piled up everywhere, hindering production management.

[0003] Some mechanical chain hoisting devices have also appeared on the market, but they often have the following shortcomings: First, they can usually only perform simple reciprocating or rotating stacking, making it difficult to achieve tight laying and resulting in low space utilization; Second, they lack effective anti-knotting design, and the chain is still easy to get tangled when conveying at high speed, requiring frequent machine stops for manual intervention, which affects continuous operation.

[0004] Therefore, it is necessary to improve existing technologies. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, a circular chain swing chain machine with high space utilization and anti-chain knotting is provided.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A circular chain swing chain machine includes a frame, an X-axis drive device, a Y-axis drive device, a guide rail, a frame body, a swing chain trolley, and an anti-knotting mechanism. The guide rail is mounted on the frame, the frame body is slidably mounted on the guide rail and driven to slide along the guide rail by the X-axis drive device, and the swing chain trolley is slidably mounted on the frame body and driven to slide along the frame body by the Y-axis drive device. The driving directions of the X-axis drive device and the Y-axis drive device are perpendicular to each other. The sway chain trolley includes a base, a motor reducer assembly I, a sprocket shaft II, and a guide chain sprocket. The motor reducer assembly I is fixedly mounted on the base. The sprocket shaft II is mounted on the base via two bearing seats II. The guide chain sprocket is mounted on the sprocket shaft II and is circumferentially limited by the sprocket shaft II. The motor shaft of the motor reducer assembly I is connected to the sprocket shaft II in a transmission connection. The anti-knotting mechanism includes a first drive shaft and a second drive shaft that are rotatably arranged relative to the frame. A synchronization mechanism is provided between the first drive shaft and the second drive shaft. A first sprocket and a second sprocket are respectively connected to the first drive shaft and the second drive shaft. A circular chain passes through the first sprocket, the second sprocket, and the guide sprocket in sequence.

[0007] Preferably, the first sprocket is eccentrically positioned relative to the first drive shaft, the circular chain between the first sprocket and the second sprocket is in a drooping state, and the circular chain between the second sprocket and the guide sprocket is in a taut state.

[0008] Preferably, the synchronization mechanism includes a synchronization sprocket I disposed on a first transmission shaft and a synchronization sprocket II disposed on a second transmission shaft. The synchronization sprocket I and the synchronization sprocket II are connected by a chain, and the transmission ratio between the synchronization sprocket I and the synchronization sprocket II is 1:1.

[0009] Preferably, the X-axis drive device includes a motor reducer assembly II and two sets of X-axis sprocket mechanisms. The motor reducer assembly II is fixedly mounted on the frame, and the two sets of X-axis sprocket mechanisms are arranged parallel to each other on the frame. The output end of the motor reducer assembly II is connected to a drive shaft, and the two ends of the drive shaft are respectively connected to one of the sprockets of the two sets of X-axis sprocket mechanisms. The motor reducer assembly II drives the two sets of X-axis sprocket mechanisms to rotate synchronously and in the same direction through the drive shaft. The two sides of the frame are fixedly connected to the chains of two sets of X-direction sprocket mechanisms.

[0010] Preferably, the Y-direction drive device includes a Y-direction sprocket mechanism and a motor reducer assembly III fixedly connected to the frame. The Y-direction sprocket mechanism is arranged along the length of the frame. The motor reducer assembly III is drivenly connected to one of the sprockets of the Y-direction sprocket mechanism. The swing chain trolley is fixedly connected to the chain of the Y-direction sprocket mechanism.

[0011] Preferably, a guide groove is provided at the upper middle part of the frame, and a limiting device that slides with the guide groove is provided below the swing chain trolley.

[0012] Preferably, both sides of the base are connected to traveling wheels that mate with the upper surface of the frame, and the axis of the traveling wheels is perpendicular to the sliding direction of the swing chain trolley.

[0013] Preferably, the frame is provided with a first sensor for detecting the displacement of the frame body along the X direction, and the frame is provided with a second sensor for detecting the displacement of the chain trolley along the Y direction. The motor reducer assembly I, motor reducer assembly II, and motor reducer assembly III are all connected to frequency converters, which are controlled by a PLC.

[0014] The beneficial effects of this invention compared to the prior art are as follows: 1. This invention coordinates the movement of the oscillating chain trolley in a plane using mutually perpendicular X-axis and Y-axis drive devices, precisely driving the trolley along a preset S-shaped path. Combined with the continuously feeding chain by the actively rotating guide sprocket on the oscillating chain trolley, it achieves automatic, tight, and neat placement of the circular chain into the box along an S-shaped trajectory, replacing inefficient manual operation, resulting in neat placement, improved space utilization, and increased work efficiency.

[0015] 2. The anti-knotting mechanism of this invention, through the cooperation of the first sprocket, the second sprocket, and the guide sprocket, allows the chain to form a naturally drooping section between the two sprockets, automatically straightening its posture under the action of gravity. In particular, the eccentrically positioned first sprocket can apply periodic disturbances during chain operation, effectively breaking the chain's entanglement tendency, fundamentally reducing the risk of knotting, and ensuring smooth conveying and continuous production.

[0016] 3. The displacement of the frame and the trolley is detected in real time by a pull-wire sensor, and the chain speed signal and position feedback are integrated and processed by the PLC. The speed of each motor is dynamically adjusted by the frequency converter. This allows the system to automatically adapt to different chain conveying speeds, intelligently adjust the chain path and pitch, and achieve highly automated closed-loop control. It has good adaptability to different chain specifications and placement requirements. Attached Figure Description

[0019] 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.

[0020] Example: like Figures 1 to 9 As shown, a circular chain swing machine includes a frame 1, an X-axis drive device 2, a Y-axis drive device 3, a guide rail 6, a frame body 7, a swing trolley 5, and an anti-knotting mechanism 4. The frame 1 is welded from U-shaped steel and serves as the structural skeleton of the circular chain swing machine, facilitating hoisting and transportation. The guide rail 6 is mounted on the frame 1, and the frame body 7 is slidably mounted on the guide rail 6 and driven by the X-axis drive device 2 to slide along the guide rail 6. The swing trolley 5 is slidably mounted on the frame body 7 and driven by the Y-axis drive device 3 to slide along the frame body 7. The driving directions of the X-axis drive device 2 and the Y-axis drive device 3 are perpendicular to each other.

[0021] like Figure 2 As shown, when the X-axis drive device 2 drives the frame 7 to move linearly along the X-axis, the swing chain trolley 5 on the frame 7 moves linearly along the X-axis along with the frame 7. Combined with the Y-axis movement of the swing chain trolley 5 on the frame 7, the swing chain trolley 5 can achieve full-plane movement. When the chain is needed, the swing chain trolley moves along an S-shaped path in the XY coordinate system, smoothly placing the circular chain into the storage box.

[0022] To facilitate the sliding of the drive frame 7, the X-direction drive device 2 includes a motor reducer assembly II 23 and two sets of X-direction sprocket mechanisms 22. The motor reducer assembly II 23 is fixedly installed in the middle of the crossbar of the frame 1, and the two sets of X-direction sprocket mechanisms 22 are arranged parallel to each other on the upper end of the frame 1. The output end of the motor reducer assembly II 23 is connected to a drive shaft 25. The two ends of the drive shaft 25 are respectively connected to one of the sprockets of the two sets of X-direction sprocket mechanisms 22. When the drive shaft 25 rotates, the corresponding sprockets of the two sets of X-direction sprocket mechanisms 22 rotate accordingly, thereby driving the chain of the X-direction sprocket mechanism 22 to move. The two sides of the frame 7 are fixedly connected to one link of the chain of the two sets of X-direction sprocket mechanisms 22. The chain can also be an open chain. By connecting the two ends of the open chain to the frame 7, the chain can traction the frame 7.

[0023] When the motor reducer assembly II 23 drives the two sets of X-axis sprocket mechanisms 22 to rotate synchronously and in the same direction via the drive shaft 25, the two sides of the frame 7 move smoothly along the X-axis under the traction of the chain. X-axis rolling wheels 21 that cooperate with the guide rail 6 are provided on both sides of the frame 7 to reduce the running resistance of the frame 7.

[0024] The Y-direction drive device 3 includes a Y-direction sprocket mechanism 31 and a motor reducer assembly III 32 fixedly connected to the frame 7. The Y-direction sprocket mechanism 31 is arranged along the length of the frame 7. The motor reducer assembly III 32 is connected to one of the sprockets of the Y-direction sprocket mechanism 31. The swing chain trolley 5 is fixedly connected to the chain of the Y-direction sprocket mechanism 31.

[0025] Both the Y-axis sprocket mechanism 31 and the X-axis sprocket mechanism 22 adopt existing sprocket mechanisms, such as: the sprocket mechanism includes a roller chain, a driving sprocket, and a driven sprocket. The driving sprocket and the driven sprocket are mounted on the frame 1 or the frame body 7 through bearing seats and shafts, and the roller chain is mounted between the driving sprocket and the driven sprocket.

[0026] When the motor reducer assembly III 32 is working, it drives the swing chain trolley 5 to slide along the frame 7 via the Y-axis sprocket mechanism 31. Specifically, a guide groove is provided in the middle of the upper end of the frame 7, and a limiting device 56 that slides with the guide groove is provided below the swing chain trolley 5. The limiting device 56 guides the swing chain trolley 5 by sliding with the guide groove, preventing the swing chain trolley from deviating from its trajectory.

[0027] To traction the circular chain, the trolley 5 includes a base 51, a motor reducer assembly I 52, a sprocket shaft II 53, and a guide sprocket 55. A limiting device 56 is located below the base 51. Both sides of the base 51 are connected to traveling wheels 58 that mate with the upper surface of the frame 7. The axis of the traveling wheels 58 is perpendicular to the sliding direction of the trolley 5. By setting the traveling wheels 58, the moving resistance of the trolley 5 is reduced.

[0028] The motor reducer assembly I 52 is fixedly mounted on the base 51, the sprocket shaft II 53 is mounted on the base 51 through two bearing seats II 54, and the guide chain sprocket 55 is mounted on the sprocket shaft II 53 and rotates synchronously with the sprocket shaft II 53; the motor shaft of the motor reducer assembly I 52 is connected to the sprocket shaft II 53 for transmission.

[0029] When the motor reducer assembly I52 drives the sprocket shaft II53 to rotate, the sprocket shaft II53 drives the circular chain forward. In conjunction with the X-axis drive device 2 and the Y-axis drive device 3 to adjust the position of the swing chain trolley 5, the circular chain is arranged in an S-shape and enters the temporary storage box.

[0030] Preferably, the frame 1 is equipped with a first sensor to detect the displacement of the frame 7 along the X-axis, and the frame 7 is equipped with a second sensor to detect the displacement of the trolley 5 along the Y-axis. The first and second sensors can be wire sensors. Motor reducer assembly I 52, motor reducer assembly II 23, and motor reducer assembly III 32 are all connected to frequency converters, which are controlled by a PLC. Using frequency converters allows for better adjustment of the running speed, achieving a synchronous trolley effect.

[0031] The PLC receives a signal based on the speed of the equipment chain, automatically collects displacement data by using a pull-wire sensor, and automatically adjusts the position of the swing chain to achieve automatic swing chain operation.

[0032] To prevent the circular chain from knotting during traction, an anti-knotting mechanism 4 is also provided. Specifically, the anti-knotting mechanism 4 includes a first drive shaft 41 and a second drive shaft 42 rotatably mounted relative to the frame 1. A synchronization mechanism is provided between the first drive shaft 41 and the second drive shaft 42 to ensure that the first drive shaft 41 and the second drive shaft 42 rotate synchronously. Specifically, the synchronization mechanism can adopt the following structure: It includes a synchronous sprocket I 45 mounted on the first drive shaft 41 and a synchronous sprocket II 46 mounted on the second drive shaft 42. The synchronous sprocket I 45 and the synchronous sprocket II 46 are connected by a chain, and the transmission ratio between the synchronous sprocket I 45 and the synchronous sprocket II 46 is 1:1.

[0033] A first sprocket 43 and a second sprocket 44 are respectively connected to the first drive shaft 41 and the second drive shaft 42. Under the traction of the guide sprocket 55, a circular chain passes sequentially through the first sprocket 43, the second sprocket 44, and the guide sprocket 55. The circular chain between the first sprocket 43 and the second sprocket 44 is in a drooping state, allowing it to automatically align itself under gravity. The circular chain between the second sprocket 44 and the guide sprocket 55 is in a taut state, allowing the guide sprocket 55 to drive the second sprocket 44 to rotate via the circular chain.

[0034] The first sprocket 43 is eccentrically positioned relative to the first drive shaft 41. When the first drive shaft 41 rotates, the first sprocket 43 can disturb the circular chain, thereby improving the alignment effect of the circular chain.

[0035] The above description only illustrates the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes should be included within the protection scope of the present invention.
