[0062] The present invention is further described below with reference to specific embodiments:

[0063] A fully automatic sewing device includes a conveyor line 1 and a sewing head 11 arranged on a frame. The user feeds the fabric to be sewn onto the conveyor line 1, and the conveyor line 1 then feeds it to the sewing head 11 for sewing. In the patent of the present invention, a feeding mechanism 2 and a discharging mechanism 3 are also provided on the frame. The feeding mechanism 2 is used to feed the fabric to be sewn into the conveyor line 1, and the fabric to be sewn is fed to the sewing head for sewing through the conveyor line 1, and the sewn fabric is fed to the discharging mechanism 3 through the conveyor line 1 for discharging, thereby realizing automatic loading and unloading.

[0064] Specifically, the conveying line 1 includes

[0065] a table 12 for placing fabrics;

[0066] The conveyor belt 13 is arranged on the upper side of the platen 12 and a gap for fabric movement is formed between the conveyor belt 13 and the platen 12;

[0067] like Figure 2 As shown, the distance between the conveyor belt 13 and the platen 12 is sufficient for fabric to pass through. When fabric is placed between the conveyor belt 13 and the platen 12, the fabric is driven by the rotation of the conveyor belt 13. The conveyor belt 13 includes several rollers 131 connected to a power source 132, typically a drive motor, to drive the rollers 131. A belt 133 is provided between the rollers, and the friction between the belts 133 and the fabric drives the fabric on the platen 12.

[0068] Look specifically Figure 3The conveyor belt 13 includes a parallel conveyor belt 1 134 and a conveyor belt 2 135. The conveyor belt 134 is shorter than the conveyor belt 2 135. The head end of the conveyor belt 134 is arranged flush with the head end of the conveyor belt 2 135, so that a phase difference section is left at the rear side of the conveyor belt 134, and the presser foot 111 of the sewing machine head 11 is located at the rear side of the conveyor belt 134. When the conveyor belt 13 is working, the conveyor belt 1 134 and the conveyor belt 2 135 are respectively in contact with the left and right sides of the cloth and drive the cloth to move. At this time, the conveyor belt 134 and the conveyor belt 2 135 are in contact with each other at the same time to ensure the stable operation of the cloth; when the cloth is sent to the end of the conveyor belt 134, one end of the cloth is still in contact with the conveyor belt 2 135 and is driven by the conveyor belt 2 135, while the other end of the cloth is in contact with the presser foot 111 of the sewing head 11 arranged on the rear side of the conveyor belt 134. After sensing the cloth, the sewing head 11 starts the sewing motor to sew.

[0069] The conveyor belt 13 also has other forms. It can be provided with only one conveyor belt 2 135, with the conveyor belt 2 135 contacting one side of the fabric for conveying. However, in comparison, the form of a single conveyor belt 13 is unstable in conveying and easily causes the fabric to deviate, thereby affecting sewing.

[0070] Furthermore, a plurality of supports 15 are provided on the frame near the conveyor belt 13, a protective bracket 14 is installed on the support 15, the conveyor belt 13 is installed on the lower side of the protective bracket 14, and one end of the roller 131 is connected to the protective bracket 14 wrapped around the outside of the conveyor belt 13, as shown in FIG. Figure 2 As shown, the protective bracket 14 is L-shaped and mainly protects the top and sides of the conveyor belt 13. The protective bracket 14 is fixedly connected to one end of the roller 131 from the inside, and the other end of the roller 131 is connected to the power source 132 that drives it to rotate. The corresponding roller 131 is provided with a bearing for its own rotation. The protective bracket 14 in this practical application is further provided with a clearance portion after the conveyor belt 134 is provided to accommodate the sewing machine head 11. The protective bracket 14 is connected to a plurality of support members 15, which are used to support the protective bracket 14 and the conveyor belt 13, so that the conveyor belt 13 is suspended on the upper side of the platen 12.

[0071] like Figure 2 、 4As shown, the support member 15 includes a support column 151 arranged on the side of the conveyor belt 134, and a support handle 152 is provided on the support column 151 facing the side of the protective bracket 14. The support handle 152 is connected to the protective bracket 14, and the support member 15 is L-shaped as a whole; a connection hole is provided on the end of the support handle 152, and the connection is made by driving screws into the connection hole and the protective bracket 14. The overall structure of the support column 151 is compact, small in size, and easy for users to install and fix. Users can also use the form of hoisting to fix and install the conveyor line 1, but the hoisting form takes up too much space and is not easy to adjust.

[0072] The support column 151 includes an upper support column 1511 and a lower support column 1512. The upper support column 1511 is lifted and lowered on the lower support column 1512. The height of the conveyor belt 13 can be adjusted by adjusting the height of the upper support column 1511. Figure 6 As shown, an elliptical hole is provided on the upper support column 1511, and a corresponding connecting hole is provided on the lower support column 1512. By moving the upper support column 1511 and then connecting it, the relative position of the connecting hole of the lower support column 1512 in the elliptical hole is changed, thereby achieving the height adjustment of the support column 151. The support column 151 can also be implemented in the form of a telescopic rod, that is, the upper support column 1511 and the lower support column 1512 are connected by a piston sleeve and a piston rod, and the height of the support column 151 is achieved by pneumatic, hydraulic, or other means.

[0073] like Figure 4 、 5 As shown, the support column 151 is fixed on a movable table 16, and the movable table 16 includes a movable plate 161, and a horizontal slide groove 162 is provided on the movable plate 161, and a horizontal slide rail 163 is provided under the movable plate 161; the power source 132 is also fixed on the movable plate 161 and is arranged on one side of the movable plate 161; in a normal state, the movable plate 161 is located below the table 12, so that the power source 132 and the support column 151 located on one side are located on one side of the conveyor belt 13, so that the support column 151, the power source 132 and the conveyor belt 13 can be installed and connected; and the purpose of providing the slide rail 163 is to move the position of the movable plate 161 through the slide rail 163 structure, thereby realizing the adjustment of the horizontal position of the support column 151 and the power source 132, thereby facilitating installation and debugging to the most suitable installation position.

[0074] Furthermore, the protective bracket 14 is also provided with a tensioning mechanism arranged toward the belt 133, including a plurality of cloth pressing plates 141 fixed on the inner side of the conveyor belt 13 and abutting against the conveyor belt 13; the cloth pressing plate 141 generally includes a vertical connecting rod and a square abutting plate arranged at the end of the vertical connecting rod, and the abutting plate abuts against the back of the belt 133, thereby achieving tensioning.

[0075] Furthermore, the sewing head 11 is further provided with a sensor 17 and a sensor 2 18 in the feeding and discharging directions of the conveyor belt 13, for detecting the travel of the material to be sewn; when it is detected that the fabric to be sewn is about to enter the sewing head 11, the power source 132 is controlled to control the deceleration of the conveyor belt 13. Specifically, the sensor 17 and the sensor 2 18 are photoelectric sensors, which are fixed to the sewing head 11 via the mounting bracket 112 and are located on the upper side of the table 12. They detect the fabric on the table 12 downward. That is, when the fabric is conveyed under the sensor 17 or the sensor 2 18, the sensor 1 17 or the sensor 2 18 detects a signal. This detection signal is passed through an internal control circuit to control the speed of the power source 132, such as through a PLC or single-chip microcomputer. The speed is reduced while the fabric is being sewn, and the internal control circuit simultaneously controls the sewing head 11 to perform the sewing operation. To ensure efficient conveying, the fabric requires a relatively high speed during transport, but such a high speed is not necessary during sewing, as excessive speed will affect sewing quality. The general control logic is that after sensor 17 detects the fabric, the conveyor belt 13 decelerates, and sewing is performed while the fabric passes through the presser foot 111. A photoelectric sensor is provided at the presser foot 111 to detect the sewing progress. After the fabric is finished and delivered, sensor 2 18 detects the fabric. If sensor 1 17 does not detect the fabric, the conveyor belt 13 accelerates and continues transporting until the next piece of fabric is delivered. In fact, a thread trimming assembly is also provided on the rear side of the sewing head 11 to trim the fabric, removing excess thread. Sensor 2 18 is the triggering condition for this.

[0076] The feeding mechanism 2 of the fully automatic sewing equipment includes.

[0077] A material storage component, used for placing the fabric to be transported;

[0078] The needle assembly 21 is used to pick up the cloth by piercing the cloth with the needle;

[0079] A driving assembly, used to drive the needle assembly 21 to move between the storage assembly and the conveyor line 1 to transport the cloth, which at least includes an advance and retreat conveying assembly 22 and a lifting conveying assembly 23;

[0080] like Figure 7 、 8As shown, the feeding mechanism 2 is arranged on one side of the conveyor line 1. An external support surface is externally connected to one side of the conveyor line 1. The support surface is provided with the storage assembly, which is specifically a feed tray 24. The fabric to be transported is stacked in the feed tray 24. A second mounting bracket 26 is provided on one side of the feed tray 24. The second mounting bracket 26 is supported by a plurality of profiles. The forward and backward conveying assembly 22 is provided on the second mounting bracket 26. The forward and backward conveying assembly 22 is specifically located on a front-to-back electric cylinder. Sensors are provided at both ends of the electric cylinder to indicate the front and rear limits of the electric cylinder. The forward and backward conveying assembly 22 is connected to the lifting conveying assembly 23, that is, the lifting conveying assembly 23 is fixed to the slider of the electric cylinder. The lifting conveying assembly 23 is specifically a vertically arranged electric cylinder. Sensors are also provided on both sides of the electric cylinder to indicate the upper and lower limits of the electric cylinder. The needle assembly 21 is provided at the end of the forward and backward conveying assembly 22.

[0081] like Figure 11 As shown, the needle assembly 21 includes a plurality of needle cylinder heads 211 and a fixing base 212. The needle cylinder heads 211 are distributed and fixed on the fixing base 212 to extend the needles. In this embodiment, the fixing base 212 is U-shaped, with the needle cylinder heads 211 respectively provided at the four corners of the U. During use, the user stacks the fabric on the feed tray 24, and the needle cylinders are transported to the fabric on the feed tray 24 via the lifting and conveying assembly 23 and the forward and backward conveying assembly 22. At this time, the needle cylinder heads 211 are in operation, and the needles inside them extend and penetrate the fabric. After the needles are fixed and taken out through friction with the fabric, the needles are then moved by the lifting and conveying assembly 23 and the forward and backward conveying assembly 22 until the needle assembly 21 moves to the conveyor line 1. At this time, the needles in the needle cylinder heads 211 are retracted to discharge the fabric. Typically, the length of the needle is comparable to the thickness of the fabric, allowing the needle to pick up only one piece of fabric at a time. The present invention utilizes a needle assembly 21, a forward / retractable conveyor assembly 22, and a lifting / lowering conveyor assembly 23 to automatically transport the fabric, eliminating the need for manual material placement by the user, reducing labor and increasing material delivery efficiency. In addition to the needle cylinder head 211, other structures capable of extending the needle can also achieve the connection and clamping effect described in the present invention.

[0082] Furthermore, in order to adapt the structure as Figure 1The conveyor line 1 structure shown in the patent of the present invention is also provided with a feeding assembly 25, including a pressing plate 251 that is lifted and lowered on the table 12, and the pressing plate 251 is connected to a pressing plate driving cylinder 252 that drives it forward or backward; before the needle assembly 21 transports the cloth to the table 12, the pressing plate 251 rises to make room for placing the cloth, and after the needle assembly 21 transports the cloth to the table 12, the pressing plate 251 descends to abut the cloth, and the pressing plate 251 is pushed forward by the pressing plate driving cylinder 252 to transport the cloth.

[0083] The pressing plate 251 can be connected to a lifting cylinder to realize its function, that is, the lifting cylinder drives the pressing plate 251 to move up and down. The present invention provides a simple lifting form that does not require additional mechanisms; Figure 2 、 4 As shown, the pressing plate 251 is connected to the support plate 253, and the two ends of the support plate 253 are respectively set high and low. The lower end of the support plate 253 is connected to the pressing plate 251, and the high end is connected to the pressing plate driving cylinder 252; Figure 2 The support plate 253 is an iron plate with an inclined or curved setting. Due to its own curvature or inclination, it has a lower end and a higher end. The curvature or inclination causes the pressure plate 251 at the lower end to abut against the table 12. When the cloth is placed under the pressure plate 251, the inclination of the support plate 253 itself will fix and drive the cloth. At the same time, the pressure plate driving cylinder 252 is also fixed on the second mounting bracket 26, so that the pressure plate driving cylinder 252 and the forward and backward conveying assembly 22 are located in the same horizontal position, that is, the support plate 253 is located on the running track of the needle assembly 21. Therefore, when the forward and backward conveying assembly 22 drives the needle assembly 21, since the needle assembly 21 itself has a certain width, the needle assembly 21 will abut against the curved or inclined support plate 253, thereby lifting the lower end of the support plate 253 upward to clear the space. There is space left for placing the fabric, and the needle assembly 21 is now unloading the fabric. After unloading is completed, the forward and backward conveying assembly 22 retracts and no longer abuts the support plate 253. The support plate 253 returns to its original position, with its lower end abutting the fabric placed on the table 12. Then, the pressing plate driving cylinder 252 works to push the support plate 253 and the pressing plate 251 forward so that the fabric contacts the moving conveyor belt 13. The moving conveyor belt 13 brings the fabric from under the pressing plate 251 into the conveyor belt 13. The pressing plate 251 has a simple and convenient structure and does not require an additional lifting mechanism, which saves costs and is easy to manufacture.

[0084] Further, if Figure 9As shown, the table 12 is further provided with a material-forming drive cylinder 27 on one side of the pressure plate 251, and a straight material-forming plate 271 is provided at one end of the material-forming drive cylinder 27; when the cloth is fed onto the table 12, the material-forming drive cylinder 27 drives the material-forming plate 271 toward one side end of the cloth until it is pushed to the maximum distance that the material-forming drive cylinder 27 can extend; in the process of pushing the material-forming plate 271, the position of the cloth is corrected by the abutment of the straight material-forming plate 271, so as to prevent the cloth from being unevenly stacked in the feed tray 24, resulting in uneven transportation.

[0085] Further, if Figure 9 As shown, the pressing plate 251 is positioned horizontally on the table 12 and includes an abutment portion 2511 lying flat on the table 12 and a connecting portion 2512 perpendicular to the abutment portion 2511. Both the abutment portion 2511 and the connecting portion 2512 are constructed of iron plates. The flattened position of the pressing plate 251 effectively increases the contact area with the fabric, facilitating fabric transport. The support plate 253 is connected to the abutment portion 2511 near one end of the material-manipulating drive cylinder 27. This ensures a more compact structure at the pressing plate 251. Generally, the material-manipulating drive cylinder 27 is positioned to one side of the pressing plate 251, rather than directly in the center.

[0086] Furthermore, a lifting assembly 28 is provided at the bottom of the feed tray 24, comprising a lifting motor 281 and a screw 282 driven by the lifting motor 281, and the screw 282 is connected to the feed tray 24; since each piece of cloth in the feed tray 24 has a certain thickness, the height of the entire cloth pile will change accordingly after it is transported, but the distance moved by the lifting and conveying assembly 23 each time is constant, that is, general lifting cylinders are limited up and down by fixed sensor positions; and the purpose of setting up the cover lifting assembly 28 is that each time the cloth is grabbed, the lifting assembly 28 will compensate for the height lost by the grabbing of the cloth, thereby eliminating the need to adjust the distance moved by the lifting and conveying assembly 23. In comparison, the use of the lifting assembly 28 is simpler and facilitates the realization of height compensation. Figure 10 As shown, a panel is provided on the other end of the screw 1 282, and a plurality of auxiliary screws 1 283 are provided on the panel to connect the panel and the bottom of the feed tray 24, so as to make the lifting of the screw 1 282 more stable.

[0087] The discharging mechanism 3 of the fully automatic sewing equipment includes

[0088] The material storage component 31 is used to store the processed fabrics;

[0089] A material pushing assembly is provided above the material storage assembly and is used to push the cloth onto the material storage assembly;

[0090] Among them, the pusher assembly includes

[0091] A pushing platform 32 is provided with an opening 33;

[0092] The pushing cylinder 34 is arranged above the opening 33 of the pushing platform 32; when the cloth is conveyed to the pushing platform 32 and straddles the opening 33, the pushing cylinder 34 descends to push the cloth onto the storage assembly 31.

[0093] like Figure 12 As shown, one end of the conveyor line 1 is provided with the feeding mechanism 2, and the other end is provided with the discharging mechanism 3. Figure 13 The material storage assembly 31 and the material pushing platform 32 are respectively fixed on the bracket at the end of the conveyor line 1. The material pushing platform 32 is specifically a cover plate arranged above the receiving tray, including a front cover plate 321 and a rear cover plate 322 arranged in parallel, and the opening 33 is left between the front cover plate 321 and the rear cover plate 322; the front cover plate 321 and the rear cover plate 322 are square and have a certain width; the material pushing cylinder 34 is specifically a cylinder, and a vertical material pushing plate 341 is provided on the material pushing cylinder 34. The material pushing plate 341 is square and pushes the cloth located on the opening 33 through its square edge; in this embodiment, the front cover plate 321 and the rear cover plate 322 , the pushing plate 341 and the opening 33 formed between the front cover 321 and the rear cover 322 are all wider than the cloth, and the length of the opening 33 is less than the length of the cloth; when the cloth is on the opening 33, the pushing cylinder 34 abuts against the cloth downward, and the cloth is folded in half due to the front cover 321 and the rear cover 322 until the entire cloth is pushed under the opening 33. Since the front cover 321 and the rear cover 322 and the opening 33 formed between the front cover 321 and the rear cover 322 have a certain width, the cloth will only be folded in half when pushed, and no other additional wrinkles will be generated, thereby ensuring the quality of the cloth to a certain extent.

[0094] Furthermore, the rear cover plate 322 is arranged lower than the front cover plate 321, so that the cloth can pass through the opening 33 and enter the rear cover plate 322 from the front cover plate 321 due to the height difference. Figure 14As shown, mounting angle irons 35 are provided on both sides of the cover plate 32 for securing to the machine frame. The mounting angle irons 35 are L-shaped, with one side secured to the machine frame and the other side having a connection hole for connecting to the front cover plate 321 or the rear cover plate 322. The front cover plate 321 and the rear cover plate 322 are secured to the front and rear sides of the mounting angle irons 35, respectively, resulting in a height difference between the front cover plate 321 and the rear cover plate 322. When the cloth is fed to the cover plate 32 and passes through the opening 33, due to its own supporting force, when there is nothing underneath to support it, it will slowly bend downward until it becomes vertical. During this time, if the cloth is transported for too long, it may bend excessively, causing one end of the cloth to fall into the opening 33, causing abnormal cloth transportation and affecting stacking. The height difference between the front cover plate 321 and the rear cover plate 322 effectively compensates for this problem, compensating for the height difference caused by the cloth falling during transportation. In fact, if the conveying speed of the conveying line 1 is fast enough, the height difference may not be set, and the fabric can still cross the opening 33.

[0095] Furthermore, an L-shaped mounting bracket 36 is provided on one side of the pushing platform 32, and a pushing cylinder 34 is provided downwardly on the end of the mounting bracket 36. Figure 14 As shown, the bracket is fixed to the frame of the automatic sewing equipment by screws and other connecting parts. A sensor 37 is also fixed to the mounting bracket 36 and is located above the rear cover 322 through the mounting bracket 36. The sensor 37 can be a photoelectric sensor. When fabric is blocked between the sensor 37 and the rear cover 322, the push cylinder 34 will work to stack the fabric. To ensure the quality of the push platform 32, the push platform 32 is made of metal. However, metal has a poor sensing effect on the photoelectric sensor 37 and may affect the operation of the photoelectric sensor 37. To ensure the normal operation of the photoelectric sensor 37, a sensing portion 371 corresponding to the sensor 37 is provided on the rear cover 322. The sensing portion 371 is specifically adapted to the sensor 37. In this example, the sensing portion 371 can be a sticker, and the sticker surface can be used for sensing, thereby meeting the normal reflection requirements of the photoelectric sensor 37.

[0096] Furthermore, the storage component 31 is specifically a receiving tray, and a lifting component 2 38 is provided at the bottom of the receiving tray, including a lifting motor 2 381 and a screw 2 382 driven by the lifting motor 2 381, and the screw 2 382 is connected to the storage component 31; since each piece of cloth has a certain thickness, when they are stacked in sequence, the height of the entire cloth pile will gradually increase, but the distance that the pushing cylinder 34 moves each time is constant, that is, the general pushing cylinder 34 is limited up and down by the fixed position of the sensor 3 37; and the purpose of setting the lifting component 2 38 is that after the cloth is stacked in sequence, the lifting component 2 38 descends to compensate for the height difference caused by the stacking of the cloth, thereby eliminating the need for the pushing cylinder 34 to move a certain distance each time. In comparison, the use of the lifting component 2 38 is simpler and easier to implement. Figure 16 As shown, a panel is provided on the other end of the screw 2 382, ​​and a plurality of auxiliary screws 2 383 are provided on the panel to connect the panel and the bottom of the storage assembly 31, so as to make the lifting of the screw 2 382 more stable.

[0097] Furthermore, the storage component 31 is provided with a receiving surface 311 for placing the cloth. In some embodiments, the receiving surface 311 may be a plane; however, the thickness of the discharged cloth may be uneven, but the distance that the lifting component 2 38 descends is constant, which will cause a deviation between the cloth height and the descending height. In the long run, the cloth pile on the storage component 31 may be too high or too low. When the cloth pile is too high and exceeds the height of the pushing cylinder 34 after it is descended, the pushing cylinder 34 may be damaged.

[0098] To solve this problem, Figure 15 As shown, the receiving surface 311 includes an inclined section 3111 and a horizontal buffer section 3112. The storage assembly 31 is provided with a guardrail on the outside, and a plate is installed inside the storage assembly 31. The plate is provided with a bending point, thereby forming the inclined section 3111 and the buffer section 3112. When the cloth is pushed onto the receiving surface 311, the cloth is located at the bending point, the side of the cloth located at the inclined section 3111 is the high point, and the side of the cloth located at the buffer section 3112 is the low point; when working, the pushing cylinder 34 abuts against the high point of the cloth to stack the cloth. When the cloth being transported each time is too thick, the pushing cylinder 34 abuts against the high point of the cloth, and causes the cloth pile to slide down along the inclined section 3111 toward the buffer section 3112, thereby correspondingly reducing the height of the cloth pile. The above structure solves the height difference problem caused by uneven cloth.

[0099] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
