Technical Field

[0001] This invention relates to the field of loom equipment technology, and in particular to an automatic fabric feeding mechanism and control method for a loom. Background Technology

[0002] In existing technologies, the fabric unloading process on a loom typically requires manual operation. The fabric roll needs to be manually loaded, and once the amount of fabric on the roll reaches production requirements, the fabric must be cut, the roll removed, and transported to the next process. This purely manual operation suffers from high labor intensity and low production efficiency. Furthermore, manual cutting of the fabric makes it impossible to finish the cut edges, resulting in frayed edges. Therefore, designing an automated fabric unloading mechanism that enables automatic loading of the fabric roll, automatic cutting of the fabric, and automatic unloading of the roll is the problem that the inventors aim to solve. Summary of the Invention

[0008] Preferably, the automatic loading module includes a loading drive assembly and a loading transmission assembly. The loading drive assembly includes a loading servo motor, the output shaft of which is fixedly connected to a pinion gear. The loading servo motor is bolted to a loading motor bracket, which is bolted to a loading base. The loading base is bolted to a lower wall panel. The loading transmission assembly includes a fabric roller support bolted to the lower wall panel. The fabric roller support is connected to a rotating disk via ball bearings. A transmission screw passes through the center of the fabric roller support and the rotating disk. The rotating disk is threadedly connected to the transmission screw. The end of the transmission screw is fixedly connected to a fabric roller top seat that abuts against the end of the fabric roller via ball bearings.

Two L-shaped rotating shaft brackets are symmetrically arranged on the left support at the through hole. The automatic disassembly pedal passes through the through hole and the middle of the two L-shaped rotating shaft brackets. The two L-shaped brackets and the automatic disassembly pedal are rotatably connected by a rotating shaft. A Y-shaped push plate is provided on the top of the automatic disassembly pedal.

[0010] Preferably, the left and right supports are respectively provided with arc-shaped grooves that fit with the fabric rolling roller.

[0011] Preferably, the long clamping plate is provided with a wire rope guard.

[0012] A control method includes a controller and a display screen, the control method comprising: (a) When the amount of fabric woven on the roll of the loom reaches the production requirement during the loom production process, the employee issues a fabric dropping command through the display screen, and the automatic fabric dropping mechanism of the loom starts to work; (b) The controller sends a command to the relay to turn on the transformer and control the heating wire to start heating. The real-time temperature of the heating wire is fed back to the controller through the temperature sensor. When the real-time temperature of the heating wire reaches 800~900℃, the controller sends a command to the cutting servo motor driver: the output shaft of the cutting servo motor rotates forward, and the heating wire swings a certain amplitude through mechanical transmission and contacts the fabric. After that, the cutting servo motor stops for a period of time. During the period when the cutting servo motor is stationary, the heating wire uses its own high temperature to cut the fabric. After the fabric is cut, the relay is disconnected, the heating wire is de-energized, the output shaft of the cutting servo motor reverses and drives the heating wire back to the starting point. After that, the cutting servo motor stops running, the cutting is completed, and the loading mechanism retraction command is executed. (c) The controller sends a command to the driver of the loading servo motor: the output shaft of the loading servo motor reverses to drive the top seat of the fabric roll away from the fabric roll, and the loading servo motor stops running after the top seat of the fabric roll retracts to the farthest point. The loading mechanism completes the retraction and begins to execute the unloading command. (d) The controller sends a command to the driver of the unloading servo motor: the output shaft of the unloading servo motor rotates forward to drive the automatic disassembly pedal of the roll roll to swing back and forth, so that the roll roll is disengaged from the roll roll support shaft and the unloading servo motor stops running. The roll roll is unloaded and waits for the roll roll to be replaced. (e) After replacing the fabric-loaded roll with an empty roll, the infrared sensor switch transmits a signal to the controller, which in turn sends a command to the driver of the loading servo motor: the output shaft of the loading servo motor rotates forward, causing the roll top seat to approach the roll and apply a force to the roll after contact, so that the left side of the roll is pressed against the roll support shaft; at this time, the roll has no radial displacement, the automatic loading mechanism enters the locked state, and the loading servo motor enters the low torque standby mode; when the loom starts running, the roll support shaft rotates, and the roll support shaft locking point coincides with the groove on the left side of the roll, the left side of the roll screws into the roll support shaft, the loading servo motor stops running, and the roll loading is completed. Preferably, the controller is a PLC or a microcontroller.

[0013] This invention has the following advantages over existing technologies: In the electric heating wire cutting module, the swinging amplitude of the electric heating wire support rod moves the electric heating wire from a point away from the fabric to a point of contact with the fabric, and returns to the starting point after completing the cutting action. During its movement towards the fabric, the electric heating wire is energized and heated, and upon contact with the fabric, it uses the high temperature to cut the fabric. In the automatic loading module, the radial rotation of the rotating disk is converted into the axial movement of the transmission screw through a screw drive. The transmission screw moves towards the lower end plate of the loom, causing the top seat of the fabric roll to move away from the right end face of the fabric roll. After the top seat of the fabric roll moves away to the corresponding distance, the fabric roll loading mechanism completes its operation. In the automatic unloading module, the automatic disassembly pedal of the fabric roll swings back and forth, causing the Y-shaped push plate above it to act on the left end face of the fabric roll, causing the fabric roll to be axially displaced from the fabric roll support shaft, thus realizing the unloading function of the fabric roll. Through the coordinated operation of the components of each functional module, the automation level of the loom's fabric unloading process is improved, the operator's workload is reduced, production efficiency is increased, and lean production is achieved.

[0016] The invention will now be further described with reference to the accompanying drawings.

[0017] like Figure 1 As shown, an automatic fabric feeding mechanism for a loom includes a fabric feeding roller 3 disposed between an upper wall plate 1 and a lower wall plate 2. A left support 11 is disposed on the upper wall plate 1, and a right support 21 is disposed on the lower wall plate 2. The fabric feeding roller 3 is mounted on the left support 11 and the right support 21. An electric heating wire cutting module 4 is disposed above the fabric feeding roller 3. The electric heating wire cutting module 4 includes an electric heating wire, a cutting support unit 42 for supporting the electric heating wire 41, and a cutting drive unit 43 capable of driving the support unit and the electric heating wire 41 to perform reciprocating oscillation. An automatic loading module 5 is disposed at the right end of the fabric feeding roller 3, capable of displacing the fabric feeding roller 3 axially to the left. An automatic unloading module 6 is disposed at the left end of the fabric feeding roller 3, capable of displacing the fabric feeding roller 3 axially to the right until it disengages from the fabric feeding roller support shaft 7.

[0018] This solution provides an automatic fabric doffing mechanism for a loom. During production, once the amount of fabric 8 on the roll roller 3 reaches the production requirement, it needs to be disassembled and transported to the next process. The operating steps of the automatic fabric doffing mechanism are as follows: the automatic loading module 5 can push the roll roller 3 axially to the left to cooperate with the roll roller support shaft 7; the automatic unloading module 6 can move the roll roller 3 axially to the right until it disengages from the roll roller support shaft 7, thus achieving automatic unloading of the roll roller 3. This novel automatic fabric doffing mechanism for a loom improves the automation level of the fabric doffing process, reduces the workload of workers, increases production efficiency, and achieves lean production through the coordinated operation of components in various functional modules.

[0019] In the automatic loading module 5, the radial rotation of the rotating disk 522 is converted into the axial movement of the transmission screw 523 via a screw drive. The transmission screw 523 moves towards the lower end wall plate 2 of the loom, causing the top seat 524 of the fabric roll to move away from the right end face of the fabric roll. After the top seat 524 of the fabric roll moves away to the corresponding distance, the fabric roll loading mechanism completes its operation. In the automatic unloading module 6, the automatic disassembly pedal 624 of the fabric roll swings back and forth, causing the Y-shaped push plate 6241 above it to act on the left end face of the fabric roll, causing the fabric roll to be axially displaced from the fabric roll support shaft 7, thus realizing the unloading function of the fabric roll.

[0020] Preferably, the fabric cutting support unit 42 includes a heating wire support rod 421 and end support assemblies 46 and a steering assembly disposed at both ends of the heating wire support rod 421. The end support assembly 46 is fixedly connected to one end of the heating wire 41. The steering assembly includes a long clamping sleeve 422. One end of the heating wire 41 opposite to the end support assembly 46 is also connected to a steel wire rope 423 through a joint fixing assembly 44. The long clamping sleeve 422 is provided with a steering roller 424 that contacts the steel wire rope 423. The heating wire support rod 421 is also provided with a telescopic compensation assembly 45. The telescopic compensation assembly 45 includes a short clamping sleeve 451 fixed to the heating wire support rod 421. The short clamping sleeve 451 is connected to a spring 452. The spring 452 hooks onto the end of the wire rope 423 at one end relative to the short clamp sleeve 451; the cloth cutting drive unit 43 includes a cloth cutting servo motor bracket 431 fixedly connected to the upper wall panel 1 or the lower wall panel 2, a cloth cutting servo motor 432 fixedly connected to the cloth cutting servo motor bracket 431, a worm gear 433 fixedly connected to the output shaft of the cloth cutting servo motor 432, and a support rod bearing seat 434 through which a heating wire support rod 421 can pass through is also fixedly installed on the cloth cutting servo motor bracket 431, and a worm wheel 435 meshing with the worm gear 433 is fixedly connected to the end of the heating wire support rod 421. The servo motor drives the heating wire support rod 421 and the heating wire to swing back and forth through the forward and reverse rotation of the output shaft.

[0021] Preferably, the end support assembly 46 includes an end clamp sleeve 461 sleeved on the heating wire support rod 421. The end clamp sleeve 461 is locked onto the heating wire support rod 421 by bolts and nuts, and the heating wire 41 is clamped and fixed in the middle of the end clamp sleeve 461.

[0022] Preferably, the connector fixing assembly 44 includes a connector bolt 441, two flat washers 442 sleeved on the connector bolt 441, and a connector nut 443 connected to the connector bolt 441. The ends of the heating wire 41 and the steel wire rope 423 are respectively clamped and fixed between the two flat washers 442 by the connector bolt 441 and the connector nut 443.

[0023] The purpose of using the steering roller 424 to change the direction of the wire rope 423 is to increase the width of the fabric cut by the heating wire 41 while maintaining the same reed width. The purpose of adding the telescoping compensation component 45 is that the length of the heating wire 41 increases after being energized and heated. At high temperatures, the increased length of the heating wire 41 is absorbed by the spring 452, and after cooling, the heating wire 41 retracts to its original size, ensuring that the heating wire 41 is always under tension. For looms with larger reed widths, this solution uses an end support component 46 to support and fix one end of the heating wire 41. The joint fixing component 44 tightly fixes the wire rope 423 to the heating wire 41, providing convenient operation and a good structural stability.

[0024] The periodic oscillation of the output shaft of the fabric cutting servo motor 432 changes its rotation direction through the meshing transmission of the worm gear 435 and worm 433, driving the heating wire support rod 421 to oscillate periodically. This periodic oscillation moves the heating wire 41 from a position away from the fabric 8 to a position in contact with the fabric 8, and returns to its starting point after completing the cutting action. During its movement towards the fabric 8, the heating wire 41 is energized and heats up, using its high temperature to cut the fabric 8 upon contact. The purpose of using the heating wire 41 for cutting is to use its high temperature to finish the cut edge of the fabric 8 during the cutting process. This mechanism improves the automation level of the fabric cutting process on the loom, reduces the workload of workers, and increases production efficiency.

[0025] Preferably, the automatic loading module 5 includes a loading drive assembly 51 and a loading transmission assembly 52. ​​The loading drive assembly 51 includes a loading servo motor 511, the output shaft of which is fixedly connected to a pinion 512. The loading servo motor 511 is bolted to a loading motor bracket 513, which is bolted to a loading base 514. The loading base 514 is bolted to the lower wall panel 2. The loading transmission assembly 52 includes... A fabric roller support 521 is bolted to the lower wall panel 2. The fabric roller support 521 is connected to a rotating disk 522 via ball bearings. A transmission screw 523 passes through the center of the fabric roller support 521 and the rotating disk 522. The rotating disk 522 is threadedly connected to the transmission screw 523. The end of the transmission screw 523 is fixedly connected to a fabric roller top seat 524 that can abut against the end of the fabric roller via ball bearings. A large gear 525 that meshes with a small gear 512 is fixedly connected to the outer wall of the rotating disk 522.

[0026] The pinion 512 is fixed to the output shaft of the loading servo motor 511 by a set screw. The loading servo motor 511 is fixed to the loading motor bracket 513 by four bolts. The loading motor bracket 513 is fixed to the loading base 514 by two sets of bolts. The combination of two sets of bolts and flat washers 442 passes through the fabric roll support 521 and the loading base 514 in sequence, fixing the fabric roll support 521 and the loading base 514 to the lower end wall plate 2 of the loom. The right support 21 is fixed to the lower end wall plate 2 of the loom by the combination of two sets of bolts and flat washers 442. The fabric roll support 521 restricts the radial rotation of the transmission screw 523 and realizes the axial displacement of the transmission screw 523 through a key fit. The fabric roll support 521 realizes the radial rotation of the rotating disk 522 through the fit of ball bearings and restricts the axial displacement of the rotating disk 522 through the fit of the internal boss and snap ring. The rotating disk 522 and the transmission screw 523 interact through helical transmission. The large gear 525 is fixed to the rotating disk 522 by a locking screw. The fabric roll top seat 524 is used on the left side of the transmission screw 523 through the fit of ball bearings.

[0027] During operation, the radial rotation of the output shaft of the loading servo motor 511 drives the radial rotation of the rotating disk 522 through the gear engagement of the pinion 512 and the large gear 525. The radial rotation of the rotating disk 522 is converted into the axial movement of the transmission screw 523 through a screw drive. The axial movement of the transmission screw 523 acts on the right end face of the fabric roll 3 through the fabric roll top seat 524, causing the fabric roll 3 to be axially translated to the fabric roll support shaft 7 on the left side of the fabric roll 3, thus realizing the automatic loading function of the fabric roll 3. After loading is completed, if it is necessary to unload the fabric roll, the loading servo motor 511 drives the pinion 512 to reverse, thereby causing the fabric roll top seat 524 to move away from the fabric roll in the opposite direction. The automatic loading mechanism of the fabric roll in this solution can improve the automation of the fabric roll loading process on the loom, reduce the operator's workload, and improve production efficiency.

[0028] Preferably, the automatic unloading module 6 includes an unloading drive assembly 61 and an unloading eccentric transmission assembly 62. The unloading drive assembly 61 includes an unloading servo motor 611 and a reducer 612 fixedly connected to the unloading servo motor 611. The reducer 612 is fixed on an automatic disassembly bracket 613, which is fixed on the left support 11. The unloading eccentric transmission assembly 62 includes an eccentric shaft 621, an automatic disassembly connecting rod 622, an automatic disassembly shaft 623, and an automatic disassembly pedal 624. The output shaft of the reducer 612 is fixedly connected to the inner ring of the eccentric shaft 621. The automatic disassembly connecting rod 622 includes a large ring hole 6221 and a small ring hole 6222. The outer wall of the eccentric shaft 621 is fixed in the large ring hole 6221 of the automatic disassembly connecting rod 622 by ball bearings. The automatic disassembly shaft 623 includes short shaft sections 62 connected in sequence. 31. A boss section 6232 and a long shaft section 6233 are provided. The long shaft section 6233 is fixed in the small ring hole 6222 of the automatic disassembly connecting rod 622 by a bushing. The lower part of the automatic disassembly pedal 624 is provided with a threaded hole that mates with the short shaft section 6231. The automatic disassembly shaft 623 is fixed to the automatic disassembly pedal 624 by threaded connection between the short shaft section 6231 and the threaded hole. A through hole 111 is provided on the left support 11. Two L-shaped rotating shaft brackets 625 are symmetrically arranged on the left support 11 at the through hole 111. The automatic disassembly pedal 624 passes through the through hole 111 and the middle of the two L-shaped rotating shaft brackets 625. The two L-shaped brackets and the automatic disassembly pedal 624 are rotatably connected by a rotating shaft 626. A Y-shaped push plate 6241 is provided on the top of the automatic disassembly pedal 624. The Y-shaped push plate 6241 abuts against the end face of the fabric rolling roller 3.

[0029] The unloading servo motor 611 in the unloading drive assembly 61 is fixed to the rear of the reducer 612 by four bolts. The reducer 612 is fixed to the automatic disassembly bracket 613 by four bolts. The automatic disassembly bracket 613 is fixed to the right support 21 by two bolts passing through the flat pad 442. The right support 21 is fixed to the upper wall plate 1 of the loom by two bolts passing through the flat pad 442.

[0030] The drive shaft of the reducer 612 acts on the inner ring of the eccentric shaft 621 and is locked by a locking screw. The outer ring of the eccentric shaft 621 acts on the inner side of the large ring hole 6221 of the automatic disassembly link 622 through a roller bearing. The inner side of the small ring hole 6222 of the automatic disassembly link 622 acts on the long shaft section 6233 of the automatic disassembly shaft 623 through a bushing, and the automatic disassembly link 622 and the automatic disassembly shaft 623 are axially fixed by the boss section 6232 of the automatic disassembly shaft 623 and the snap ring. The short shaft section 6231 of the automatic disassembly shaft 623 is locked by a thread to the threaded hole below the automatic disassembly pedal 624. Two L-shaped rotating shaft brackets 625 are placed in the through hole 111 above the automatic disassembly pedal 624 through a rotating shaft. The two L-shaped rotating shaft brackets 625 are fixed to the left support by a combination of four sets of bolts and flat washers 442.

[0031] This solution converts the radial rotation of the output shaft of the unloading servo motor 611 into the reciprocating swing of the automatic disassembly pedal 624 through mechanical transmission. The reciprocating swing of the Y-shaped push plate 6241 of the automatic disassembly pedal 624 is applied to the left end face of the fabric roll, causing the fabric roll to move axially away from the fabric roll support shaft 7, thereby realizing the automatic unloading function of the fabric roll.

[0032] Preferably, the left support 11 and the right support 21 are respectively provided with arc-shaped grooves that fit with the fabric rolling roller. The arc-shaped grooves can fit the fabric rolling roller more closely and provide more stable support.

[0033] Preferably, the long clamp sleeve 422 is provided with a wire rope guard 425. The wire rope guard 425 is used to protect the steering roller 424 and the wire rope 423 to prevent foreign objects from entering and causing jamming.

[0034] A control method includes a controller and a display screen, the control method comprising: (a) When the amount of fabric woven on the roll of the loom reaches the production requirement during the loom production process, the employee issues a fabric dropping command through the display screen, and the automatic fabric dropping mechanism of the loom starts to work; (b) The controller sends a command to the relay to turn on the transformer and control the heating wire 41 to start heating. The real-time temperature of the heating wire 41 is fed back to the controller through the temperature sensor. When the real-time temperature of the heating wire 41 reaches 800~900℃, the controller sends a command to the cutting servo motor driver: the output shaft of the cutting servo motor 432 rotates forward, and the heating wire 41 swings a certain amplitude through mechanical transmission and contacts the fabric. After the cutting servo motor 432 stops for a period of time, the heating wire 41 uses its own high temperature to cut the fabric 8. After the fabric 8 is cut, the relay is disconnected, the heating wire 41 is de-energized, the output shaft of the cutting servo motor 432 reverses and drives the heating wire 41 back to the starting point. After that, the cutting servo motor 432 stops running, the cutting is completed and the loading mechanism retraction command is executed. (c) The controller sends a command to the driver of the loading servo motor 511: the output shaft of the loading servo motor 511 reverses to drive the top seat 524 of the fabric roll away from the fabric roll 3, and after the top seat 524 of the fabric roll retracts to the farthest point, the loading servo motor 511 stops running, the loading mechanism completes the retraction and begins to execute the unloading command. (d) The controller sends a command to the driver of the unloading servo motor 611: the output shaft of the unloading servo motor 611 rotates forward to drive the automatic disassembly pedal 624 of the roll roll to swing back and forth, so that the roll roll 3 is disengaged from the roll roll support shaft 7 and the unloading servo motor 611 stops running. The roll roll 3 is unloaded and waits for the roll roll to be replaced. (e) After replacing the fabric roll 3 containing the fabric 8 with an empty fabric roll 3, the infrared sensor switch transmits this signal to the controller, which in turn sends a command to the driver of the loading servo motor 511: the output shaft of the loading servo motor 511 rotates forward, causing the fabric roll top seat 524 to approach the fabric roll 3 and apply a force to the fabric roll 3 upon contact, causing the left side of the fabric roll 3 to adhere tightly to the fabric roll support shaft 7; at this time, the fabric roll 3 has no radial displacement, the automatic loading mechanism enters the locked state, and the loading servo motor 511 enters the low-torque standby mode; when the loom starts running, the fabric roll support shaft 7 rotates, and the locking point of the fabric roll support shaft 7 coincides with the groove on the left side of the fabric roll 3, the left side of the fabric roll 3 screws into the fabric roll support shaft 7, the loading servo motor stops running, and the loading of the fabric roll 7 is completed.

The control method includes: (a) When the amount of fabric woven on the roll of the loom reaches the production requirement during the loom production process, the employee issues a fabric dropping command through the display screen, and the automatic fabric dropping mechanism of the loom starts to work; (b) The controller sends a command to the relay to turn on the transformer and control the heating wire to start heating. The real-time temperature of the heating wire is fed back to the controller through the temperature sensor. When the real-time temperature of the heating wire reaches 800~900℃, the controller sends a command to the cutting servo motor driver: the output shaft of the cutting servo motor rotates forward, and the heating wire swings a certain amplitude through mechanical transmission and contacts the fabric. After that, the cutting servo motor stops for a period of time. During the period when the cutting servo motor is stationary, the heating wire uses its own high temperature to cut the fabric. After the fabric is cut, the relay is disconnected, the heating wire is de-energized, the output shaft of the cutting servo motor reverses and drives the heating wire back to the starting point. After that, the cutting servo motor stops running, the cutting is completed, and the loading mechanism retraction command is executed.

The loading mechanism completes the retraction and begins to execute the unloading command. (d) The controller sends a command to the driver of the unloading servo motor: the output shaft of the unloading servo motor rotates forward to drive the automatic disassembly pedal of the roll roll to swing back and forth, so that the roll roll is disengaged from the roll roll support shaft and the unloading servo motor stops running. The roll roll is unloaded and waits for the roll roll to be replaced. (e) After replacing the fabric-loaded roll with an empty roll, the infrared sensor switch transmits this signal to the controller, which in turn sends a command to the driver of the loading servo motor: the output shaft of the loading servo motor rotates forward, causing the roll top seat to approach the roll and apply a force to the roll after contact, so that the left side of the roll is pressed against the roll support shaft; at this time, the roll has no radial displacement, the automatic loading mechanism enters the locked state, and the loading servo motor enters the low torque standby mode; when the loom starts running, the roll support shaft rotates, and when the roll support shaft locking point coincides with the groove on the left side of the roll, the left side of the roll screws into the roll support shaft, the loading servo motor stops running, and the roll loading is completed.
