Description

Technical Field

[0001] The utility model relates to the technical field of automation, in particular to a sewing machine robot loading and unloading system workstation. Background Art

[0002] Currently, sewing machine loading and unloading mostly relies on manual operation. In traditional production methods, workers place fabric on a template and manually transfer the template to the sewing machine platform for sewing. While this manual operation method meets production needs to a certain extent, rising labor costs and labor shortages have led to an increase in the cost of manual loading and unloading each year. Furthermore, manual operation is also plagued by issues such as high staff turnover, long operator training cycles, and poor operational safety. This not only increases production instability but also increases operational risks.

[0003] With the advancement of industrial automation, demand for automated loading and unloading systems for sewing machines is increasing. The use of robots for loading and unloading has become a key approach to improving production efficiency and reducing costs. Robots can flexibly operate across different models and types of sewing machines, reducing reliance on manual labor. They can also operate continuously, eliminating the limitations of manual operation, such as reducing operator fatigue and workload, while improving production safety. This shift is crucial for improving a company's production efficiency and competitiveness.

[0004] However, existing robotic loading and unloading systems still face several challenges. For example, traditional robotic systems often require individual adaptation and adjustment for each sewing machine's template, making automated systems expensive to maintain in production environments where templates are frequently changed. Furthermore, when robots and sewing machines share a workspace, efficiently coordinating operations to ensure uninterrupted loading and unloading is another challenge that needs to be overcome.

[0040] A sewing machine robot feeding and discharging system workstation, comprising a robot 1, a feeding mechanism 7, at least two transmission mechanisms 2 and a plurality of jig plates 3;

[0041] The transmission mechanisms 2 are symmetrically arranged on both sides of the input end of the feeding mechanism 7, the output ends of the two transmission mechanisms 2 are arranged close to the input end of the feeding mechanism 7, and the input ends of the two transmission mechanisms 2 are arranged away from the feeding mechanism 7, and the conveying direction of the feeding mechanism 7 is perpendicular to the conveying direction of the two transmission mechanisms 2; One side of the conveying direction of the transmission mechanism 2 is the installation area, and the other side is the activity area, the installation area is used for placing the sewing machine, and the activity area is used for workers to cooperate with feeding or / and discharging;

[0042] The transmission mechanism 2 is divided into a buffer section 202 and a feeding section 201 from the input end to the output end, the buffer section 202 is used for workers to place jig plates 3, the buffer section 202 can accommodate at least two jig plates 3 side by side along the conveying direction, the transmission mechanism 2 is used for transmitting the jig plates 3 in the buffer section 202 to the feeding section 201, the jig plates 3 are used for mounting the template, and the jig plates 3 are also used for adapting with the clamp 2 of the robot 1.

[0043] The robot 1 is installed in the installation area. The robot 1 is used to transfer the jig plate 3 located at the output end of the transmission mechanism 2 to the working surface of any sewing machine in the installation area, and is also used to transfer the jig plate 3 on the working surface of any sewing machine in the installation area to the input end of the unloading mechanism 7.

[0044] Before the fabric is processed on the sewing machine, the worker needs to perform the swing operation. The worker will place the fabric on the template of the sewing machine, and then move the template with the fabric to the working surface of the sewing machine. The sewing machine will automatically sew the fabric on the template according to the set program.

[0045] By using the workstation of the present invention, a worker places the fabric on the template of the sewing machine, then places the template on the jig plate 3, and then places the jig plate 3 on the buffer section 202 of the transmission mechanism 2. The transmission mechanism 2 moves the jig plate 3 in the buffer section 202 to the loading section 201. The robot 1 transfers the jig plate 3 in the loading section 201 to the working surface of the sewing machine, and the sewing machine automatically sews the fabric in the template on the jig plate 3. This structure can reduce the distance workers move during the loading operation and allows them to work outside the working range of the robot 1.

[0046] like Figure 1 By using two symmetrically arranged transmission mechanisms 2 and arranging the unloading mechanism 7 between the two transmission mechanisms, sufficient operating space is left for workers in the activity area to cooperate with the robot 1 in loading and unloading. The worker places the jig plate 3 on the buffer section 202 of the transmission mechanism 2. The transmission mechanism 2 moves the jig plate 3 in the buffer section 202 to the loading section 201. Finally, the unloading mechanism 7 transfers the processed jig plate 3 back to the activity area. The worker removes the template and fabric of the sewing machine on the jig plate 3 and puts the jig plate 3 back into use for loading. The buffer section 202 can accommodate at least two jig plates 3 side by side along the conveying direction, allowing the workstation to cooperate with multiple workers to load and unload materials at the same time, solving the problem that workers take a long time to place fabrics and multiple people cannot cooperate with the robot 1 in loading and unloading at the same time.

[0047] By using the jig plate 3 to carry the template of the sewing machine, the workstation is suitable for templates of various models of sewing machines. When the template model is changed during production, the workstation does not need to be adjusted, which solves the problem of the robot 1 needing to stop and replace or adjust the clamping tool to match the template when used in automated production.

[0048] Preferably, the conveying mechanism 2 is further provided with a first positioning clamp 21, a first electric eye 41 and a second electric eye 42, the first positioning clamp 21 is arranged at the feeding section 201, the first positioning clamp 21 comprises a first driver and two first pushing blocks 211, the two first pushing blocks 211 are arranged opposite to each other, and the opposite direction of the two first pushing blocks 211 is horizontally arranged perpendicular to the conveying direction of the conveying mechanism 2, the detection position of the first electric eye 41, the detection position of the second electric eye 42 and the first positioning clamp 21 are sequentially arranged along the conveying direction of the conveying mechanism 2; the first positioning clamp 21 is used for positioning the jig plate 3 in the horizontal direction perpendicular to the conveying direction of the conveying mechanism 2, the first driver is used for driving the two first pushing blocks 211 to move close to or away from each other, and the first electric eye 41 and the second electric eye 42 are used for positioning the jig plate 3 along the conveying direction of the conveying mechanism 2.

[0049] As Figure 2 , Figure 3 and Figure 4 , in specific embodiments, the distance between the second electric eye 42 and the first positioning clamp 21 along the conveying direction is less than the width of the jig plate 3, the jig plate 3 is placed on the conveying mechanism 2 and moves along the conveying direction, when the jig plate 3 moves from the buffer section 202 to the feeding section 201, the first electric eye 41 detects the jig plate 3, the conveying mechanism 2 slows down, the second electric eye 42 detects the jig plate 3, after a preset buffer time, the jig plate 3 moves to the first positioning clamp 21 along the conveying direction, then the first driver drives the first pushing blocks 211 to move close to each other to clamp the jig plate 3, so as to center the jig plate 3 and facilitate the transfer of the robot 1, at the same time, the conveying mechanism 2 restores the normal conveying speed. With this structure, it can ensure that the jig plate 3 is within the operating range of the robot 1, reduce the identification difficulty and identification time of the robot 1, solve the problem of accurate positioning of the jig plate 3 during transmission, and the problem of too long identification time of the robot 1 affecting the feeding efficiency; at the same time, the conveying mechanism 2 only slows down without stopping, and restores the normal speed after the jig plate 3 is clamped, which improves the transmission efficiency of the conveying mechanism 2, and solves the problem that the robot 1 cannot accurately position and clamp the jig plate 3 while the conveying mechanism 2 is conveying.

[0050] Preferably, the transmission mechanism 2 is also provided with a second positioning clamp 22, a third electric eye 43 and a fourth electric eye 44. The second positioning clamp 22 is arranged at one end of the buffer section 202 close to the loading section 201. The second positioning clamp 22 includes a second driver and two second push blocks 221. The two second push blocks 221 are arranged opposite to each other. The relative direction of the two second push blocks 221 is arranged horizontally perpendicular to the transmission direction of the transmission mechanism 2. The detection position of the third electric eye 43, the detection position of the fourth electric eye 44 and the second positioning clamp 22 are arranged in sequence along the transmission direction of the transmission mechanism 2; the second positioning clamp 22 is used for positioning the jig plate 3 in the horizontal direction perpendicular to the transmission direction of the transmission mechanism 2, the second driver is used to drive the two second push blocks 221 to move closer to or away from each other, and the third electric eye 43 and the fourth electric eye 44 are used for positioning the jig plate 3 along the transmission direction of the transmission mechanism 2.

[0051] like Figure 3 In a specific embodiment, the spacing between the fourth electric eye 44 and the second positioning clamp 22 along the transmission direction is smaller than the width of the jig plate 3. The jig plate 3 is placed on the transmission mechanism 2 and moves along the transmission direction. When the jig plate 3 moves from the range of the buffer section 202 away from the loading section 201 to the end close to the loading section 201, the third electric eye 43 detects the jig plate 3, and the transmission mechanism 2 slows down. After the fourth electric eye 44 detects the jig plate 3, after a preset buffer time, the jig plate 3 moves along the transmission direction to the second positioning clamp 22. The second driver drives the second pushing block 221 to approach each other and clamp the jig plate 3, so that the jig plate 3 stays in the buffer section 202, and blocks the jig plate 3 behind the transmission direction from continuing to move forward, so as to prevent the jig plate 3 from continuing to move forward and affecting the operation of the robot 1. At the same time, the transmission mechanism 2 resumes normal transmission speed. This structure can ensure that the jig plate 3 stays in the buffer section 202 in an orderly manner. After the jig plate 3 in the loading section 201 is transferred, the second positioning clamp 22 is released, and the next jig plate 3 is quickly transferred to the loading section 201. During the entire process, the transmission mechanism 2 only slows down but does not stop, which maximizes the transmission efficiency and solves the problem that the transmission mechanism 2 cannot move the jig plates 3 into the loading section 201 one by one without stopping the transmission work.

[0052] Preferably, the output end of the robot 1 is provided with a clamp 5, and the clamp 5 is provided with a plurality of floating clamping fingers. The clamping direction of the clamp 5 is parallel to the working surface of the sewing machine, and the floating clamping fingers can move perpendicular to the clamping direction. The floating clamping fingers are used to clamp the workpiece.

[0053] In an embodiment, the floating clamp finger comprises a floating shaft and a floating shaft sleeve, the floating shaft is arranged in the floating shaft sleeve, a gap is left between the outer periphery of the floating shaft and the inner periphery of the floating shaft sleeve, the gap is used to accommodate an elastic member, the elastic member is sleeved on the outer periphery of the floating shaft, one end of the floating shaft is provided with a limiting mechanism, the outer periphery of the other end of the floating shaft is provided with an outer ring protrusion, the inner periphery of the floating shaft sleeve is provided with an inner ring protrusion, the outer ring protrusion and the inner ring protrusion are arranged opposite to each other, the elastic member is located between the outer ring protrusion and the inner ring protrusion, the inner ring protrusion is located between the limiting mechanism and the elastic member, and the floating clamp finger is connected to the clamp through the floating shaft sleeve. The limiting mechanism is two limiting nuts, one end of the floating shaft is provided with a thread matched with the limiting nut, the elastic member is a compression spring, when the floating clamp finger contacts the working surface of the sewing machine in the axial direction, the floating shaft moves in the shaft sleeve in the axial direction, the compression spring is further compressed, so that the chuck is tightly attached to the working surface.

[0054] In a specific embodiment, the working surface of the sewing machine is horizontally arranged, the jig plate 3 is placed on the working surface, the jig plate 3 is provided with a clamping hole 31 matched with the floating clamp finger, the robot 1 drives the clamp 2 to move downward to approach the jig plate 3, the floating clamp finger passes through the clamping hole 31 of the jig plate 3, when part of the floating clamp finger of the clamp 2 contacts the surface of the working surface, the clamp 2 continues to move downward to approach the jig plate 3, the floating clamp finger contacting the working surface is supported by the working surface and kept stationary, the clamp 2 continues to move downward until all the floating clamp fingers contact the working surface, the clamp 2 stops moving downward, and then a plurality of floating clamp fingers move outward in the horizontal direction to support and clamp the jig plate 3.

[0055] Through the structure of the floating clamp finger of the robot 1, the clamp 5 can be tightly attached to the working surface of the sewing machine, thereby stably clamping the workpiece on the working surface, and the problem that the workpiece is turned over or falls off due to the insufficient flatness of the placement plane of the thin plate-shaped workpiece and the clamp 5 not clamping the workpiece in place is solved.

[0056] Preferably, a plurality of piece placing tables 6 are further included, the plurality of piece placing tables 6 are placed in the active area and are spaced apart along the conveying direction of the buffer sections 202 of the two conveying mechanisms 2.

[0057] The piece placing table 6 is used for workers to place pieces, the workers place an empty jig plate 3 on the piece placing table 6, then place a template of the sewing machine on the jig plate 3, and then place cloth on the template, and finally place the jig plate 3 with the cloth thereon on the conveying mechanism 2. Because placing pieces needs a certain time, and the span of the template is relatively large, a plurality of piece placing tables 6 are spaced apart to facilitate workers to simultaneously perform the placing operation, so as to cooperate with the conveying mechanism 2 and the robot 1 to perform the feeding operation, thereby increasing the feeding efficiency.

[0058] Preferably, the output end of the discharging mechanism 7 extends into the active area, and the output end of the discharging mechanism 7 is located between the two piece placing tables.

[0059] In a specific embodiment, the output end of the unloading mechanism 7 is arranged close to the plate placing table 6. After the cloth is sewn in the sewing machine, the robot 1 transfers the jig plate 3 together with the template and the cloth on it to the unloading mechanism 7, and then moves the jig plate 3 to the vicinity of the plate placing table 6. The worker unloads the cloth, and then puts the jig plate 3 and the template back to the plate placing table 6 for the next loading and placing operation.

[0060] Preferably, the unloading mechanism 7 is provided with a first sensor 71 and a second sensor 72. The detection position of the first sensor 71 is arranged at the input end of the unloading mechanism 7, and the detection position of the second sensor 72 is arranged at the output end of the unloading mechanism 7.

[0061] The unloading mechanism 7 can arrange two jig plates 3 side by side along the conveying direction. The detection position of the first sensor 71 can move up and down along the vertical direction. The first sensor 71 is used to detect the height of the jig plates 3 stacked close to the input end of the unloading mechanism 7.

[0062] As Figure 6 In a specific embodiment, during the unloading operation, the worker moves the detection position of the first sensor 71 to a preset height, and the robot 1 stacks the jig plate 3 close to the input end of the unloading mechanism 7. When the first sensor 71 detects that the stacking height of the jig plate 3 close to the output end of the unloading mechanism 7 reaches the preset height, and the second sensor 72 detects that there is no jig plate 3 at the output end away from the robot 1, the unloading mechanism 7 automatically starts to move the jig plate 3 from the end close to the robot 1 to the end away from the robot 1. When the second sensor 72 detects the jig plate 3 again, the unloading mechanism 7 stops working.

When the jig plate 3 enters the loading section 201 from the buffer section 202, the fifth sensor 45 detects. When the fifth sensor 45 detects that there is no template on the jig plate 3, the robot 1 directly moves the jig plate 3 from the conveying mechanism 2 to the unloading mechanism 7, so as to avoid the sewing machine to work on the empty jig plate 3, solve the problem of wasting time of the empty jig plate 3, and reduce the production efficiency.
