Description

TECHNICAL FIELD

[0001] The present application relates to an automatic sewing machine, more particularly, to an automatic sewing device and a control method thereof. BACKGROUND

[0002] In the process of sewing multi-layer cloth, a sewing machine is usually used for sewing the cloth. The sewing machine has a driving part capable of sewing at a fixed speed, so as to form neat and beautiful, flat and firm sewing track, and the sewing speed of the cloth is fast, and the operation is simple, which is suitable for large quantities of cloth sewing.

[0003] However, although the sewing machine on the market can realize relatively automatic sewing, the workers still need to manually take down and stack the processed cloth during operation, and the workers need to count during processing or additionally calculate the number of stacked cloth when counting the workers, which increases the labor intensity of the workers and reduces the processing efficiency. Moreover, the traditional sewing machine cannot detect the sewing thread in real time during processing, and the detection of broken thread / missing thread is usually performed after single sewing, so the processing effect is poor. SUMMARY

[0004] In view of the deficiencies of the prior art, the purpose of the present application is to provide an automatic sewing device and a control method thereof, which can automatically collect the processed cloth, has high processing efficiency, can automatically count during processing, and can actively judge the sewing thread state.

[0008] The processing rod is provided with a driving wheel, a sewing needle and a processing cutter, one side of the processing rod is provided with an electromagnet, and the cloth placing table is further provided with a baffle on the side close to the processing rod, the baffle extends into the processing rod and forms a processing area for sewing cloth between the baffle and the processing rod.

[0009] The processing rod is provided with a driving wheel, a sewing needle and a processing cutter, one side of the processing rod is provided with an electromagnet, and the cloth placing table is further provided with a baffle on the side close to the processing rod, the baffle extends into the processing rod and forms a processing area for sewing cloth between the baffle and the processing rod.

[0010] Preferably, the installation table is further provided with a waste treatment device, the waste treatment device has a waste hole penetrating through the installation table and a waste pipeline arranged in the waste hole, the other end of the waste pipeline is provided with a waste collection bag, the position of the waste hole matches the position of the cutter in the processing rod, and the waste pipeline is provided with a suction pump, the suction pump intermittently operates to suck vacuum in the waste pipeline, and the waste treatment device is used for guiding and accommodating the waste cut by the cutter.

[0011] The processing area of the cloth placing table is provided with a hinge, and the hinge is configured to control the processing area to flip along the direction perpendicular to the movement direction of the cloth.

[0012] The application also provides a control method of the automatic joint device, comprising the following steps: S1, based on the need of the sewing thread, the sewing thread roll corresponding to the pattern is installed into the placing disc on the sewing thread frame, and the sewing thread in the sewing thread roll is led out to the sewing needle on the processing rod through the sewing machine group; S2, the cloth to be sewn is placed on the cloth placing table, and the edge to be sewn is matched with the baffle of the cloth placing table. S3, the sewing device is started, the electromagnet drives the processing cutter and the sewing needle to reciprocate along the vertical direction, and the fabric on the fabric placing table driven by the processing rod is moved to cut the edge of the fabric and complete sewing; S4, the processing rod detects the sewing state of the fabric, if the fabric is sewn, the sewing is completed, and the sewing is completed, and jumps to S5 to collect the material, otherwise, if the fabric is not sewn, the current fabric is sewn; S5, the pressing rod of the pressing assembly is pushed by the push cylinder, and is in contact with the fabric placing table. The fabric in the fabric placing table is fixed by the pressing rod, and part of the fabric extends into the material collecting structure; S6, the material collecting cylinder of the material collecting structure pushes the fabric to the storage rack, and clamps the fabric through the storage rack and the material collecting cylinder. After the fabric is clamped, the air pipe blows the fabric and makes it turn over and hang on the storage rack. The material collecting cylinder is retracted to complete the material collecting process.

[0013] Preferably, the pressing rod is provided with a displacement detection device and a pressure sensor. The step S6 further includes air blowing amount control, including the following steps: S61, the pressing rod moves towards the fabric, and the pressure sensor detects the pressure P on the top of the pressing rod; S62, P is detected. If P=0, it is judged that the current pressing rod is not in contact with the fabric, and the pressing rod continues to move. Otherwise, if P≠0, it is judged that the current pressing rod is in contact with the fabric, and the displacement detection device detects the moving distance L of the pressing rod; S63, the maximum moving distance of the pressing rod is set as Lm. If Lm-L≥1, it is judged that the current fabric thickness is large, the sewing device increases the blowing intensity of the air pipe, otherwise, if Lm-L<1, it is judged that the current fabric thickness is small, and the sewing device keeps the blowing intensity of the air pipe unchanged.

[0014] Preferably, the fabric placing table is provided with an aperture for passing the fabric. The driving wheel is further provided with a pressure sensor. The sewing state detection of step S4 includes the following steps: S41, in the process of sewing, the pressure sensor detects the pressure, and the detection value is Y0; S42, Y0 is compared. If Y0≠0, it is judged that there is fabric between the fabric placing table, the fabric is moved, otherwise, if Y0=0, it is judged that there is no fabric between the fabric placing table, the current fabric sewing process is completed, and the current fabric is collected.

[0015] In the process of collecting the sewing finished cloth, if the length of the cloth is too large, the length of the cloth on one side of the collecting frame will be greater than that on the other side during the collection, so that the cloth is easy to fall after hanging. On the contrary, if the length of the cloth is too small, the cloth will be pushed away from the cloth placing table by the collection cylinder, affecting the collection effect. Therefore, it is necessary to adjust the distance between the collecting frame and the cloth placing table. As a control of the distance of the collecting frame, the length of the cloth during sewing is calculated, that is, the feeding amount L1 from the beginning of sewing to the end of sewing, and a fixed length L is set as the hanging length when the cloth is collected. The fixed length is the distance between the pressing rod and the edge of the installation table close to the collecting structure side. If L1>2L, the cloth hanging on one end of the collecting frame is longer during the collection, and the collecting frame needs to be adjusted to move away from the installation table, and the distance between the collecting frame and the installation table is 0.5L1.

[0016] At the same time, in the process of detecting the thickness of the cloth, after the pressing rod presses the cloth, the pressure received by the pressing rod is detected, and the normal value of the pressure is set as N. The N is the pressure when the cloth is abutted on the cloth placing table during the pressing process of the pressing rod. Generally, when there is no impurity at the bottom of the cloth, the pressure detected by the pressing rod is the normal value. On the contrary, if there is impurity at the bottom of the cloth, the pressure value detected by the pressing rod is>N. By detecting the pressure value, the stability of the pressing rod when pressing the cloth is ensured, and the effect of the collection is prevented from being affected by the impurity at the bottom of the cloth.

[0017] By adopting the technical scheme, beneficial effects are achieved: 1. In the sewing process, the automatic material collecting structure is arranged, so that the material collecting operation can be automatically performed after the determination of the completion of the cloth processing, replacing the manual stacking and storage operation, and the counting device is arranged in the sewing machine group and matched with the material collecting structure, so that the counting operation is simultaneously performed while the material is collected, the labor intensity of the workers is reduced, and the displacement detection device and the pressure sensor are arranged in the pressing rod, the pressure sensor can determine the contact state of the current pressing rod and the cloth placing table, when the pressure value ≠ 0, it is determined that the cloth is pressed by the pressing rod, then the displacement sensor detects the moving distance of the pressing rod and obtains the thickness of the current cloth, finally, the blowing force of the blowing pipe is controlled based on the thickness of the processed cloth, for example, when the cloth is sewn and the thickness is large, a large blowing force is required to turn it over, and whether the cloth is processed is determined through pressure detection, so that the subsequent material collecting operation is performed, thereby forming a continuous and efficient automatic processing, forming a full-process automatic detection processing from cloth sewing to material collecting, avoiding the intervention of manual operation, improving the production effect, and the waste treatment device is arranged on the mounting table, so that the waste such as the waste cloth edge and the thread end can be directly discharged through the waste treatment device during the sewing process, preventing the accumulation of waste on the processing table from affecting the processing effect, and the air pump is intermittent, saving energy consumption.

[0018] 2. Further, in the process of collecting the material, the pressing assembly is arranged on the top of the sewing machine group, the pressing assembly includes the mounting bracket arranged on the top of the sewing machine group and the pressing rod arranged in the mounting bracket, the pressing rod is in abutment with the cloth placing table through the push cylinder, specifically, after the cloth is sewn, the cloth moves to the end of the cloth placing table, if the sewn cloth is too long, the cloth length arranged on the cloth placing table is less than the cloth length exposed outside the cloth placing table, which will cause the cloth to directly slide off, the cloth is abutted by the pressing assembly before the material is collected, after the cloth is fixed, the cloth is abutted by the material storage rack through the material collecting cylinder, forming the fixation of both ends of the cloth, at the same time, in order to realize the stacking and storage of the cloth in the material storage rack, the pressing rod cancels the fixation of the cloth, and the cloth is blown by the blowing pipe due to the abutment of the material storage rack, and the cloth can be hung on the material storage rack after being turned over, and the distance of the material storage rack extending to the outside of the mounting table can be adjusted, so as to change the cloth length fixed by the material collecting cylinder after abutting the cloth, ensure the consistency of the cloth length at both ends of the material storage rack, and avoid the problem of falling of the stacked cloth.

[0019] 3、Meanwhile, the sewing device can detect the thickness of the fabric during the sewing process, and the fabric of different thickness can be blown and collected at one time, thereby improving the processing quality and the qualified rate of the product.

[0020] 4、Meanwhile, the pressure sensor is arranged on the device, and the pressure sensor is used for detecting the position of the fabric. When the fabric is sewn, the fabric inevitably needs to pass through the gap between the fabric placing table and the fabric placing table and apply pressure, and Y0≠0 at this time. Conversely, when the fabric processing is completed, there is no fabric between the fabric placing table and the fabric placing table, and Y0=0 at this time. The state of the fabric can be directly and rapidly judged, the detection precision is high, and the subsequent pressing and collecting processes can be directly controlled based on the detection. The processing is coherent between the processes, the waiting during the process switching is avoided, and the smoothness and efficiency of the automatic production process are ensured.

[0031] The processing area of the cloth placing table 4 is provided with a hinge, the hinge is configured to control the processing area to flip along the vertical direction perpendicular to the movement direction of the cloth.

[0032] The application also provides a control method of the automatic sewing device, comprising the following steps: S1, based on the need of the thread, the thread roll corresponding to the pattern is installed into the placing disc on the thread rack, and the thread in the thread roll is drawn out to the sewing needle on the processing rod through the sewing machine group; S2, the cloth to be sewn is placed on the cloth placing table, and the edge of the cloth to be sewn is matched with the baffle of the cloth placing table; S3, the sewing device is started, the electromagnet drives the processing cutter and the sewing needle to reciprocate along the vertical direction, and the cloth on the cloth placing table driven by the processing rod moves, the edge of the cloth is cut at the same time, and the sewing is completed; S4, the processing rod detects the sewing state of the cloth, if the sewing of the cloth is completed, the thread is cut off to complete the sewing, and jumps to S5 to collect the material, otherwise, if the sewing of the cloth is not completed, the current cloth is continuously sewn; S5, the pressing rod of the pressing assembly is pushed by a push cylinder and abuts against the cloth placing table, the cloth in the cloth placing table is fixed by the pressing rod, and part of the cloth extends into the material collecting structure; S6, the material collecting cylinder of the material collecting structure pushes the cloth to the storage rack, and clamps the cloth through the storage rack and the material collecting cylinder, after the cloth is clamped, the air blowing pipe blows the cloth and makes it turn and hang on the storage rack, and the material collecting cylinder is retracted to complete the material collecting process.

[0033] Preferably, the pressing rod is provided with a displacement detection device and a pressure sensor, and the step S6 further comprises air blowing amount control, comprising the following steps: S61, the pressing rod moves towards the cloth, and the pressure sensor detects the pressure P on the top of the pressing rod; S62, P is detected, if P=0, it is judged that the current pressing rod does not abut against the cloth, the pressing rod continues to move, otherwise, if P≠0, it is judged that the current pressing rod abuts against the cloth, the displacement detection device detects the moving distance L of the pressing rod; S63, the maximum moving distance of the pressing rod is set as Lm, if Lm-L≥1, it is judged that the current cloth thickness is large, the sewing device increases the blowing strength of the air blowing pipe, otherwise, if Lm-L<1, it is judged that the current cloth thickness is small, and the sewing device keeps the blowing strength of the air blowing pipe unchanged.

[0034] Preferably, the cloth placing table is provided with an aperture for passing the cloth, and the driving wheel is further provided with a pressure sensor, and the step S4 of sewing state detection comprises the following steps: S41, in the process of sewing, the pressure sensor detects the pressure, and the detection value is Y0; S42, Y0 is compared, if Y0≠0, it is judged that there is cloth between the cloth placing table, the cloth continues to move, otherwise, if Y0=0, it is judged that there is no cloth between the cloth placing table, the current cloth sewing process is completed, and the current cloth is collected.

[0035] In the process of collecting the cloth after sewing, if the length of the cloth is too large, the length of the cloth on one side of the storage rack will be greater than that on the other side during the collection, so that the cloth is easy to fall after hanging, otherwise, if the length of the cloth is too small, the cloth will be separated from the cloth placing table 4 when the material collecting cylinder 52 pushes, which affects the collection effect, therefore, it is necessary to adjust the distance between the storage rack and the cloth placing table 4; As the control of the distance between the material receiving rack and the sewing machine, the feeding amount L1 from the beginning of sewing to the end of sewing is calculated during the sewing process, and a fixed length L is set as the hanging length when the material is received, which is the distance between the pressing rod 62 and the edge of the installation table 1 close to the material receiving structure 5. If L1>2L, the material hanging at one end of the material receiving rack is too long during the material receiving process, and the material receiving rack needs to be adjusted to move away from the installation table 1, and the distance between the material receiving rack and the installation table 1 is 0.5L1.

[0036] At the same time, during the detection of the thickness of the material, after the pressing rod 62 presses the material, the pressure on the pressing rod 62 is detected, and the normal value of the pressure is set as N, which is the pressure when the material is abutted on the material placing table 4 during the pressing process of the pressing rod 62. Generally, when there is no impurity at the bottom of the material, the pressure detected by the pressing rod 62 is the normal value, otherwise, if there is impurity at the bottom of the material, the pressure value detected by the pressing rod 62>N. By detecting the pressure value, the stability of the pressing rod 62 pressing the material is ensured, and the effect of the material receiving is prevented from being affected by the impurity at the bottom of the material.

[0037] During the sewing process, the automatic material receiving structure 5 is provided, which can automatically receive the material after determining that the material processing is completed, replacing the manual stacking and storage operation, and the counting device is provided in the sewing machine group 21 to match the material receiving structure 5, which can simultaneously perform the counting operation while receiving the material, reducing the labor intensity of the workers. In addition, the displacement detection device and the pressure sensor are provided in the pressing rod 62, the pressure sensor can determine the contact state between the current pressing rod 62 and the material placing table 4, and when the pressure value≠0, it is determined that the pressing rod 62 presses the material. Then, the displacement sensor detects the moving distance of the pressing rod 62 and obtains the thickness of the current material, and finally, the blowing force of the blowing pipe 53 is controlled based on the thickness of the processed material. For example, when the material is sewn and the thickness is large, a large blowing force is needed to turn it over, and the pressure detection is used to determine whether the material processing is completed, so as to perform the subsequent material receiving operation, thereby forming a continuous and efficient automatic processing, forming a whole process automatic detection processing from material sewing to material receiving, avoiding the intervention of manual work, improving the production effect, and the waste treatment device 7 is provided on the installation table 1, which can directly guide the waste such as the waste material edge and the thread end out of the waste treatment device 7 during the sewing process, preventing the accumulation of waste on the processing table from affecting the processing effect, and the air pump 74 is intermittent, which saves energy consumption.

[0038] Further, in the process of collecting the material, a pressing assembly 6 is arranged on the top of the sewing machine group 21, which includes a mounting bracket 61 arranged on the top of the sewing machine group 21 and a pressing rod 62 arranged in the mounting bracket 61. The pressing rod 62 is in abutment with the cloth placing table 4 through a push cylinder 63. Specifically, after the cloth is sewn, the cloth moves to the end of the cloth placing table 4. If the sewn cloth is too long, the length of the cloth arranged on the cloth placing table 4 is less than the length of the cloth exposed outside the cloth placing table 4, which will cause the cloth to directly slide off. Before the material is collected, the pressing assembly 6 is used to abut the cloth. After the cloth is fixed, the collecting cylinder 52 pushes the cloth to abut the storage rack 51, thereby fixing both ends of the cloth. At the same time, in order to realize the stacking and storage of the cloth on the storage rack 51, the pressing rod 62 blows the cloth through the blowing pipe 53 while canceling the fixation of the cloth. Due to the abutment of the storage rack 51, the cloth can be hung on the storage rack 51 after being reversed. In addition, the distance of the storage rack 51 extending to the outside of the mounting table 1 can be adjusted, so as to change the length of the cloth fixed after the abutment of the collecting cylinder 52, thereby ensuring the consistency of the length of the cloth at both ends of the storage rack 51 and avoiding the problem of the cloth falling off after being stacked.

[0039] At the same time, in the process of sewing, a displacement detection device and a pressure sensor are arranged. Specifically, the pressure on the pressing rod 62 is detected. When the pressure value P=0, it indicates that the pressing rod 62 does not abut the cloth, and the pressing rod 62 continues to move. Conversely, if the pressure value P≠0, it indicates that the pressing rod 62 abuts the cloth. The displacement detection device detects the moving distance L of the pressing rod 62. The maximum moving distance of the pressing rod 62 is Lm, and the thickness of the cloth is Lm-L. The sewing device 2 adjusts the blowing strength of the blowing pipe 53 based on the thickness of the cloth. The above design can detect the thickness of the sewn cloth while sewing, so that the cloth of different thicknesses can be collected by blowing at one time, thereby improving the processing quality and the qualification rate of the product.

[0040] In addition, a pressure sensor is arranged on the top of the cloth placing table 4. When the cloth is sewn, it inevitably needs to pass through the gap between the cloth placing table 4 and apply pressure. At this time, Y0≠0. Conversely, when the cloth processing is completed, there is no cloth between the cloth placing table 4. At this time, Y0=0. The state of the cloth can be directly and quickly judged, the detection accuracy is high, and the subsequent pressing and collecting processes can be directly controlled based on the detection. The processing is continuous between each process, which avoids the waiting time when the process is switched, thereby ensuring the smoothness and efficiency of the automatic production process.

[0041] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. Any modification and replacement within the technical scheme of the present application made by those skilled in the art shall be included in the protection scope of the present application.

At the same time, the fabric on the processing rod moves the fabric at the fabric placement table, cutting the edge of the fabric and completing the sewing at the same time. S4. The processing rod detects the sewing status of the fabric. If the sewing of the fabric is completed, the sewing thread is cut to complete the sewing, and the process jumps to S5 to collect the fabric. Otherwise, if the sewing of the fabric is not completed, the sewing of the current fabric continues. S5. The pressing rod of the pressing assembly is pushed by the pushing cylinder and abuts against the fabric placement table. The fabric in the fabric placement table is fixed by the pressing rod, and part of the fabric extends into the receiving structure. S6. The receiving cylinder of the receiving structure pushes the fabric to the storage rack, and clamps the fabric through the storage rack and the receiving cylinder. After the fabric is clamped, the air pipe blows the fabric and makes it flip and hang on the storage rack. The receiving cylinder retracts to complete the receiving process.

8. The control method for an automatic seam-sealing device according to claim 7, characterized in that, The pressure bar is equipped with a displacement detection device and a pressure sensor. Step S6 also includes air volume control, which includes the following steps: S61, the pressure bar moves in the direction of fabric fabrication, and at the same time the pressure sensor detects the pressure P on the top of the pressure bar. S62. Detect P. If P=0, it is determined that the current pressure bar is not in contact with the fabric, and the pressure bar continues to move. Otherwise, if P≠0, it is determined that the current pressure bar is in contact with the fabric, and the displacement detection device detects the moving distance L of the pressure bar. S63. Set the maximum moving distance of the pressure bar to Lm. If Lm-L≥1, it is determined that the current fabric thickness is large, and the sewing device increases the blowing force of the air pipe. Conversely, if Lm-L<1, it is determined that the current fabric thickness is small, and the sewing device keeps the blowing force of the air pipe unchanged.

9. The control method for an automatic seam-sealing device according to claim 7, characterized in that, A gap for the fabric to pass through is provided between the drive wheel and the fabric placement platform. A pressure sensor is also provided on the drive wheel. The sewing status detection in step S4 includes the following steps: S41. During the sewing process, the pressure sensor detects the pressure it receives, and the detection value is Y0. S42. Compare Y0. If Y0≠0, it is determined that there is fabric between the current fabric and the fabric placement table. Continue running and move the fabric. Otherwise, if Y0=0, it is determined that there is no fabric between the current fabric and the fabric placement table. The sewing process of the current fabric is completed, and the current fabric is collected.
