[0045] As Figures 1-2 shown, a multi-person multi-machine computer car circulating line, comprising: a circulating conveyor belt device, a plurality of computer cars 200 and a plurality of stacking devices 300;

[0046] The circulating conveyor belt device is used to transport the sewing template 700, the computer car 200 is used to sew the sewing template 700, and the stacking device 300 is adjacent to the circulating conveyor belt device and the computer car 200;

[0047] Among them, the stacking device 300 includes an inlet air cylinder assembly 310 and an outlet air cylinder assembly 320;

[0048] The feeding cylinder assembly 310 extends from the stacking device 300 to the circulating conveyor belt device, and is used to transfer the sewing template 700 from the circulating conveyor belt device to the stacking device 300.

[0049] The discharging cylinder assembly 320 extends from the stacking device 300 to the computerized sewing machine 200, and is used to transfer the sewing template 700 from the stacking device 300 to the computerized sewing machine 200.

[0050] The computerized sewing machine 200 and the stacking device 300 are located on one side of the circulating conveyor belt device, and multiple workers are located on the other side of the circulating conveyor belt device to fix the fabric workpiece on the sewing template 700, and the sewing template 700 is transferred to the other side through the circulating conveyor belt device.

[0051] In the prior art, the sewing template 700 is a standard part, and the sewing template 700 is symmetrically provided with positioning columns 710 on both sides, and the computerized sewing machine 200 fixes the sewing template 700 by grabbing the positioning columns 710 through the telescopic clamp. The feeding cylinder assembly 310 and the discharging cylinder assembly 320 also transfer the sewing template 700 through the positioning columns 710 on the sewing template 700. For example, the feeding cylinder assembly 310 and the discharging cylinder assembly 320 also fix the sewing template 700 by using the telescopic clamp.

[0052] The stacking device 300 pre-stores the sewing template 700 transferred from the circulating conveyor belt device through the feeding cylinder assembly 310, and if the stacking device 300 is full, the sewing template 700 is circulated on the circulating conveyor belt device.

[0053] After the computerized sewing machine 200 completes sewing, the processed sewing template 700 on the computerized sewing machine 200 is removed through the discharging cylinder assembly 320, and the pre-stored sewing template 700 in the stacking device 300 is moved to the computerized sewing machine 200 through the discharging cylinder assembly 320.

[0054] Multiple workers only need to fix the workpiece fabric on the sewing template 700, and ensure that the sewing template 700 in the stacking device 300 is sufficient, and the feeding and discharging of the computerized sewing machine 200 are automatically completed by the equipment, which reduces the standby time of the computerized sewing machine 200 and improves the production efficiency.

[0055] That is, under the premise that the sewing template 700 in the stacking device 300 is sufficient, the operator needs to leave the work station for a short time to go to the toilet or the like, and the computerized sewing machine 200 will not be stopped to affect the production efficiency.

[0056] And a plurality of computer car 200 through the circulating conveyor belt device connection, can meet the diversity and complexity of processing needs, feeding cylinder assembly 310 and discharge cylinder assembly 320 reverse operation, namely the realization of sewing template 700 from computer car 200 to the circulating conveyor belt device, both to achieve a plurality of computer car 200 linkage processing purpose, reduce manual handling sewing template 700 transfer station steps, reduce labor intensity, improve production efficiency.

[0057] In the embodiment, the circulating conveyor belt device comprises: an assembly conveyor belt assembly 110 and a feeding conveyor belt assembly 120, the feeding conveyor belt assembly 120 is close to the side of the stacking device 300;

[0058] Both ends of the assembly conveyor belt assembly 110 and the feeding conveyor belt assembly 120 are provided with a direction changing circulating assembly 400;

[0059] The direction changing circulating assembly 400 is located above the assembly conveyor belt assembly 110 and the feeding conveyor belt assembly 120, and is used for transferring the sewing template 700 between the assembly conveyor belt assembly 110 and the feeding conveyor belt assembly 120.

[0060] Compared with the use of a circular conveyor belt assembly, the use of two adjacent straight conveyor belt assemblies occupies less space, costs less, is easy to maintain, facilitates the positioning of the sewing template 700 and has better operability. The positioning of the sewing template 700 is a prerequisite for a series of automatic operations.

[0061] The direction changing circulating assembly 400 is provided above both ends of the assembly conveyor belt assembly 110 and the feeding conveyor belt assembly 120, and is used for the circulation of the sewing template 700 between the two straight assembly conveyor belt assemblies 110 and the feeding conveyor belt assemblies 120.

[0062] In the embodiment, the assembly conveyor belt assembly 110 and the feeding conveyor belt assembly 120 comprise a conveyor bracket, a conveyor belt rotatably installed in the conveyor bracket, and a motor driving the rotation of the conveyor belt.

[0063] The surface of the conveyor belt is provided with a plurality of positioning baffles 130, and the positioning blocks are arranged on the conveyor brackets on both sides of the conveyor belt.

[0064] The distance between the positioning baffles 130 is equal to the length of the sewing template 700; the distance between the positioning blocks on both sides of the conveyor bracket is equal to the width of the sewing template 700. The sewing template 700 involves positioning in four directions, front, back, left and right, on the plane of the transmission belt.

[0065] The two adjacent positioning baffles 130 cooperate to prevent the sewing template 700 from shifting or swaying on the conveyor belt; the transmission bracket and the corresponding positioning blocks are used to prevent the sewing template 700 from shifting or swaying back and forth on the conveyor belt. That is, on the conveyor belt, the front, back, left and right sides of the sewing template 700 abut against the positioning blocks and positioning baffles 130 respectively.

[0066] To further eliminate errors, the conveyor belts of the assembly conveyor belt assembly 110 and the feeding conveyor belt assembly 120 can adopt intermittent fixed-distance rotation, which provides a good positioning and gripping condition for the feeding cylinder assembly 310.

[0067] like Figure 3 As shown, in this embodiment, the reversing circulation assembly 400 includes a positioning block 410, a reversing cylinder 420, and a reversing lifting cylinder 430.

[0068] The reversing cylinder 420 is horizontally fixed above the assembly conveyor belt assembly 110 and the feeding conveyor belt assembly 120;

[0069] The reversing lifting cylinder 430 is connected to the positioning block 410 and the reversing cylinder 420. The reversing lifting cylinder 430 is used to drive the positioning block 410 to perform reciprocating lifting motion.

[0070] The positioning block 410 is provided with positioning holes 440 corresponding to the positioning posts 710 of the sewing template 700.

[0071] During operation, the reversing lifting cylinder 430 drives the positioning block 410 to descend, so that the positioning post 710 on the sewing template 700 is located in the positioning hole 440. Then the reversing cylinder 420 is activated, driving the sewing template 700 to change lanes between the assembly conveyor belt assembly 110 and the feeding conveyor belt assembly 120 to complete the cycle.

[0072] In this embodiment, a flat plate is provided between the two ends of the assembly conveyor belt assembly 110 and the feeding conveyor belt assembly 120 to eliminate gaps, which helps the sewing template 700 to slide and change lanes between the assembly conveyor belt assembly 110 and the feeding conveyor belt assembly 120.

[0073] In the embodiment, the direction-changing circulating assembly 400 comprises an empty material identification sensor for identifying whether there is material in the sewing template 700 and controlling the direction-changing circulating assembly 400. The end of the assembly conveying belt assembly 110 and the feeding conveying belt assembly 120 in the conveying direction is provided with an empty material recycling box, and if the empty material identification sensor identifies that there is no material fixed on the sewing template 700 below the direction-changing circulating assembly 400, in order to avoid the empty template flowing into the computerized sewing machine 200 to cause a fault, the direction-changing circulating assembly 400 is not started, so that the empty sewing template 700 falls into the empty material recycling box. Through the direction-changing circulating assembly 400 with the empty material identification sensor, the function of preventing mistakes is achieved, and unnecessary equipment faults are effectively reduced.

[0074] As shown in Figure 4 In the embodiment, a plurality of template identification devices 500 are arranged above the feeding conveying belt assembly 120, and the template identification devices 500 correspond to the stacking devices 300 one by one.

[0075] The sewing template 700 is provided with an identification part 720, and the template identification device 500 is used for identifying the identification part 720 on the sewing template 700 and controlling the stacking device 300.

[0076] The identification part 720 generally adopts a two-dimensional code, and a plurality of different computerized sewing machines 200 can respectively perform a plurality of different processes, that is, different two-dimensional code sewing templates 700 correspond to different computerized sewing machines 200. In order to distinguish and avoid confusion, the template identification device 500 identifies the identification part 720 on the sewing template 700 to distinguish the sewing template 700, that is, the template identification device 500 controls whether the feeding cylinder assembly 310 of the stacking device 300 is started. If the two-dimensional code of the sewing template 700 matches the process of the computerized sewing machine 200, the feeding cylinder assembly 310 is used to transfer the sewing template 700 on the circulating conveying belt device to the stacking device 300, and if it does not match, the feeding cylinder assembly 310 is not started.

[0077] As shown in Figure 5 In the embodiment, the stacking device 300 comprises a stacking support 350, a lifting frame 330 slidingly installed in the stacking support 350, and a lifting mechanism for driving the lifting frame 330 to make vertical reciprocating motion.

[0078] The stacking support 350 is provided with a feeding port and a discharging port.

[0079] The lifting frame 330 is provided with a plurality of material supporting plates 340.

[0080] The material supporting plate 340 is provided with a material monitoring sensor.

[0081] The material tray 340 is used to hold the sewing template 700, and the material monitoring sensor is used to monitor whether there is a sewing template 700 on the material tray 340.

[0082] The feeding port faces the feeding conveyor assembly 120. When a sewing template 700 passes through, the template recognition device 500 is matched. If it is matched, the lifting frame 330 adjusts the height so that the empty material tray 340 is flush with the feeding port. The feeding cylinder assembly 310 is started to push the sewing template 700 on the feeding conveyor assembly 120 into the feeding port and into the material tray 340.

[0083] The discharge port faces the computer vehicle 200. When the computer vehicle 200 needs to be fed, the lifting frame 330 adjusts the height so that the material tray 340 with the sewing template 700 is flush with the discharge port. The discharge cylinder assembly 320 is started to push the sewing template 700 in the material tray 340 to the computer vehicle 200.

[0084] In this embodiment, the sewing template 700 enters the lifting frame 330 from the feeding port and slides out of the discharge port. The lifting frame 330 has multiple material trays 340 for holding the sewing template 700 in the vertical direction. Therefore, during the actual feeding and discharging process, the height of the lifting frame 330 needs to be adjusted to adapt to the discharge port and the feeding port.

[0085] The preparation work before use is as follows:

[0086] The monitoring sensors on different material trays 340 need to be numbered to identify each material tray 340.

[0087] One material tray 340 is designated as the origin flush with the feeding port and the discharge port.

[0088] The height difference of different material trays 340 relative to the feeding port and the discharge port is recorded to control the lifting distance of the lifting frame 330.

[0089] When the sewing template 700 needs to be stored, according to the triggering condition of the material monitoring sensor, the material tray 340 without the sewing template 700 is selected, and the height of the lifting frame 330 is adjusted according to the number of the material monitoring sensor so that the empty material tray 340 is flush with the feeding port, facilitating the transfer of the sewing template 700 to the empty material tray 340.

[0090] When the sewing template 700 needs to be taken out, according to the triggering condition of the material monitoring sensor, the material tray 340 with the sewing template 700 is selected, and the height of the lifting frame 330 is adjusted according to the number of the material monitoring sensor so that the material tray 340 with the sewing template 700 is flush with the discharge port, facilitating the transfer of the sewing template 700 to the computer vehicle 200.

[0091] In the embodiment, the lifting mechanism includes a lead screw 360 and a motor. The lead screw 360 is rotationally fixed in the stacking support 350, and the lead screw 360 is threadedly connected with the lifting frame 330. The motor is used to drive the rotation of the lead screw 360. The driving precision of the lead screw 360 is higher, and the virtual position is smaller. The pitch of the lead screw 360 is input, that is, the lifting distance of the lifting frame 330 can be controlled by controlling the number of rotations of the lead screw 360. Compared with the air cylinder driving, the lead screw 360 driving is more stable. Compared with the conveying belt, the heavy capacity of the lead screw 360 is stronger, the virtual position is smaller, and the precision is higher.

[0092] In the embodiment, the number of the lead screw 360 is two or more, and a synchronous pulley 370 is fixed on each lead screw. The synchronous pulleys are connected by a synchronous toothed belt 380. Because the lifting frame 330 is provided with a plurality of material supporting plates 340, the load of the lifting frame 330 is large. In order to avoid the lifting frame 330 from being stuck due to uneven stress and tilting during lifting, the lead screws 360 are uniformly distributed, so that the lifting frame 330 is uniformly stressed during lifting, and the stability of the lifting movement of the lifting frame 330 is improved.

[0093] In the embodiment, the motor is a stepping motor. The stepping motor is an electric motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. For each input pulse signal, the rotor rotates an angle or moves forward by one step. The output angular displacement or linear displacement is proportional to the number of input pulses, and the rotation speed is proportional to the pulse frequency. By controlling the number of pulse signals, the rotation of the lead screw 360 can be controlled, and the lifting distance of the lifting frame 330 can be controlled.

[0094] In the embodiment, the material monitoring sensor is a visual sensor, a micro sensor, a pressure sensor, or an infrared component.

[0095] In the embodiment, the material monitoring sensor is a micro sensor, and the micro sensor is fixed on the side of the material supporting plate 340. When the sewing template 700 enters the material supporting plate 340, the sewing template 700 will press the micro sensor, that is, the material monitoring sensor of the material supporting plate 340 of the layer is triggered, and it is marked that the material supporting plate 340 of the layer has the sewing template 700.

[0096] In the embodiment, the material monitoring sensor is an infrared emitter and an infrared receiver, and the infrared emitter and the infrared receiver are respectively located on both sides of the material supporting plate 340. When the sewing template 700 enters the material supporting plate 340, the sewing template 700 is located between the infrared emitter and the infrared receiver, and the infrared receiver loses the signal, that is, it is marked that the material supporting plate 340 of the layer has the sewing template 700.

[0097] In the embodiment, the material monitoring sensor is a pressure sensor, which is fixed at the joint of the material supporting disc 340 and the descending frame. When the sewing template 700 enters the material supporting disc 340, the index of the pressure sensor changes, i.e. an electric signal is generated, indicating that the material supporting disc 340 of this layer has the sewing template 700.

[0098] In the embodiment, the material monitoring sensor is a visual sensor, and the sewing template 700 is provided with an identification part 720 corresponding to the visual sensor. When the sewing template 700 enters the material supporting disc 340, the visual sensor identifies the identification part 720 of the sewing template 700, i.e. an electric signal is generated, indicating that the material supporting disc 340 of this layer has the sewing template 700.

[0099] As shown in Figure 6 In the embodiment, one side of the computer vehicle 200 is adjacent to the stacking device 300, and the other side of the computer vehicle is provided with a guide plate 600 connected to a collection box; the discharging cylinder assembly 320 extends from the stacking device 300 to the other side of the computer vehicle 200.

[0100] The collection box is located at one side of the assembly conveying belt assembly 110, and the guide plate 600 is connected to the computer vehicle 200 and the collection box at both ends. When it is necessary to recycle the processed sewing template 700, the discharging cylinder assembly 320 grabs the sewing template 700 and moves to the edge of the computer vehicle 200, and under the action of gravity, the sewing template 700 falls down and is guided by the guide plate 600 to fall into the collection box under the circulating conveying belt device. The collection box is located at one side of the assembly conveying belt assembly 110, which is convenient for the workers to carry and count, and does not need to be additionally wound to the side of the computer vehicle 200, thereby improving the work efficiency.

[0101] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not used to limit the present application.
