In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0032] like Figures 1 to 11 As shown, a preferred embodiment of an automated production equipment for air cushion product components of the present invention includes an unwinding station 01, a punching conveyor rack 02, a punching unloading station 03, a first welding machine 04, a stacking conveyor line 05, a material transfer conveyor rack 06, a screen printing machine 07, a drying machine 08, a main traction roller 09, a second welding machine 10, a punching and slitting station 11, a multi-line integration mechanism 12, a third welding machine 13 and a cross-cutting material receiving device 14.

[0033] like Figure 2 As shown, the unwinding station 01 includes a first unwinder a and a second unwinder b. The first unwinder a is assembled with coil A0112, and the second unwinder b is assembled with coil B0113. The first unwinder a and the second unwinder b can work simultaneously, and respectively provide processed materials 15 to equipment corresponding to different processes, and simultaneously process two kinds of materials 15 for use in subsequent production and assembly processes, thereby improving production efficiency.

[0034] like Figure 3 and Figure 4 As shown, the first unwinder a and the second unwinder b both include an unwinding frame 011 and an unwinding base 012. The unwinding frame 011 is movably mounted on the unwinding base 012 via a shifting mechanism 013. The unwinding frame 011 includes two assembly positions 0111 for mounting coils, a transmission roller assembly 014, and two cutting knives 015 for cutting materials. The material 15 on the coil A 0112 / coil B 0113 is continuously transferred to the punching conveyor frame 02 via the transmission roller assembly 014. The specific structure of the transmission roller assembly 014 can be referred to the attached drawings. Those skilled in the art can also easily think of various alternatives to achieve the above functions, so they will not be described in detail.

[0035] In this embodiment, the shift mechanism 013 includes a shift cylinder 0131, a shift guide rail 0132 and a shift slider 0133. The fixed end and the movable end of the shift cylinder 0131 are respectively mounted on the unwinding base 012 and the unwinding rack 011. The unwinding rack 011 and the unwinding base 012 are respectively provided with a shift guide rail 0132 and a shift slider 0133 that cooperate with each other. The shift cylinder 0131 pushes and pulls the unwinding rack 011 back and forth in the horizontal direction, thereby realizing the deviation correction of the material 15.

[0036] The first unwinder a can be equipped with two coils A0112, and the second unwinder b can be equipped with two coils B0113, one for use and one for backup. Two cutting knives 015 are interspersed in the gap of the driving roller assembly 014, corresponding to the two coils installed on the two assembly positions 0111, that is, one cutting knife 015 is used to cut the material 15 provided by the main coil A0112 / coil B0113, and the other cutting knife 015 is used to cut the material 15 provided by the backup coil A0112 / coil B0113.

[0037] The roll materials A0112 and B0113 used in this embodiment are both roll materials with a maximum diameter of 0.5m, a paper tube diameter of 58mm, and a weight of 300kg, and can output a translucent TPU film with a thickness of 0.1mm and a width of 1.58m.

[0038] The unwinding rack 011 in this embodiment is also provided with two ultrasonic distance measuring sensors 016, which are respectively arranged toward the two assembly positions 0111 to measure the diameter of the coil. During the production process, when the coil needs to be replaced, the material 15 provided by the corresponding coil is cut by the cutting knife 015, and then the material 15 of another coil is pulled to the driving roller assembly 014, thereby continuing the production process, reducing the equipment downtime, and improving production efficiency.

[0039] During operation, the materials are first loaded manually, and the coil A0112 to be processed is installed on the assembly position 0111 of the first unwinder a, and the coil B0113 to be processed is installed on the assembly position 0111 of the second unwinder b; then the material 15 is pulled to the transmission roller assembly 014, and the material 15 is transported to the punching conveyor frame 02 through the transmission roller assembly 014 for subsequent production.

[0040] The punching conveyor rack 02 is arranged between the first unwinding machine a and the first welding machine 04, and is used to convey the material 15 provided by the first unwinding machine a to the first welding machine 04 via the punching and unloading station 03; the punching and unloading station 03 is arranged on the side of the punching conveyor rack 02, and is used for punching the air nozzle hole and installing the air nozzle; the feeding end of the first welding machine 04 is arranged downstream of the punching conveyor rack 02 for welding; the upstream of the stacking conveyor line 05 is arranged at the discharging end of the first welding machine 04, and the downstream of the stacking conveyor line 05 is arranged on the front side of the main traction roller 09.

[0041] like Figure 5 As shown, the punching conveyor frame 02 is provided with a plurality of first rollers 021, a first traction roller 022 and a first flattening roller 023. The punching unloading station 03 includes a first punching machine 031, a unloading device 032 and a mechanical arm 033. The first punching machine 031 is arranged on the side of the punching conveyor frame 02. The unloading port of the unloading device 032 and the punching position of the first punching machine 031 are both arranged within the travel range of the mechanical arm 033. The laminating conveyor line 05 is provided with a plurality of second rollers 051, a plurality of second traction rollers 052 and a second flattening roller 053.

[0042] In this embodiment, the first punching machine 031 is movably installed on one side of the punching conveyor frame 02 through a cylinder, so that the first punching machine 031 can move forward and backward relative to the material 15. When the first punching machine 031 moves forward, it punches at a preset punching position. When the first punching machine 031 moves backward, it completely avoids the punching position, which is convenient for the robot arm 033 to install the air nozzle.

[0043] During operation, the material 15 output by the first unwinder a successively passes through a first roller 021, a first flattening roller 023 and a first pulling roller 022, and is transported to the punching and unloading station 03, and the air nozzle hole is punched on the material 15 by the first punching machine 031; then, the first punching machine 031 moves backward, and the robot arm 033 grabs the air nozzle at the discharge port of the unloading device 032 and then moves to the punching position and puts it down, thereby completing the placement of the air nozzle; the material 15 continues to flow, and is transported to the first welding machine 04 through the remaining first rollers 021, and the air nozzle and the air nozzle hole are welded together by the first welding machine 04; the welded material 15 successively passes through multiple second rollers 051, multiple second pulling rollers 052 and the second flattening roller 053, and is transported to the main pulling roller 09 for subsequent processing.

[0044] In order to improve the accuracy of the air nozzle hole, the punching conveyor frame 02 is also provided with a reel deviation correction sensor 024. The reel deviation correction sensor 024 in this embodiment is installed at the first traction roller 022. When the reel deviation correction sensor 024 detects that the material 15 is offset, the reel frame 011 is moved through the shifting mechanism 013 to automatically correct the material 15 without manual intervention.

[0045] The material transfer and conveying frame 06 is arranged between the second unwinder b and the main traction roller 09. The screen printing machine 07 and the drying machine 08 are arranged in sequence along the discharge direction of the second unwinder b and are located within the travel range of the material transfer and conveying frame 06, so as to be used for printing, spraying and drying respectively.

[0046] like Figure 6As shown, the material transfer conveyor frame 06 includes a loading conveyor group 061, a unloading conveyor group 062 and a camera module 063. The loading conveyor group 061 is arranged between the second unwinding machine b and the screen printing machine 07, the unloading conveyor group 062 is arranged between the dryer 08 and the main traction roller 09, and the camera module 063 is arranged toward the unloading conveyor group 062.

[0047] In this embodiment, the loading conveying group 061 includes a plurality of third passing rollers 0611 , a third pulling roller 0612 and a third flattening roller 0613 , and the unloading conveying group 062 includes a plurality of fourth passing rollers 0621 , a fourth pulling roller 0622 and a fourth flattening roller 0623 .

[0048] During operation, the material 15 output by the second unwinder b successively passes through multiple third rollers 0611, the third traction roller 0612 and the third flattening roller 0613 and is then transported to the screen printer 07. A pattern is printed on the material 15 by the screen printer 07, and then the pattern is dried by the dryer 08. After drying, the material 15 successively passes through multiple fourth rollers 0621, the fourth traction roller 0622 and the fourth flattening roller 0623 and is then transported to the main traction roller 09 with the printed surface facing upward.

[0049] The main traction roller 09 is used to stack the material 15 welded by the first welding machine 04 and the material 15 dried by the dryer 08 and then transport them to the second welding machine 10.

[0050] like Figure 7 As shown, the downstream of the stacking conveyor line 05 and the unloading conveyor group 062 are both located at the front side of the main traction roller 09 , and the rear side of the main traction roller 09 is correspondingly arranged at the feeding end of the second welding machine 10 .

[0051] In this embodiment, the first unwinding machine a, the punching conveyor frame 02, the punching unloading station 03 and the first welding machine 04 are arranged at a position far away from the main traction roller 09, so that the stacking conveyor line 05 is erected above the second unwinding machine b, the material transfer conveyor line, the screen printing machine 07 and the dryer 08, and the downstream of the stacking conveyor line 05 merges with the downstream of the unloading conveying group 062 at the front side of the main traction roller 09.

[0052] During operation, the two groups of materials 15 conveyed by the laminating conveyor line 05 and the unloading conveying group 062 are flattened by the corresponding second flattening roller 053 or the fourth flattening roller 0623 and then overlapped. The material 15 with the air nozzle installed covers the printing surface of the printed material 15. After the two groups of materials 15 are conveyed to the main traction roller 09, they are conveyed to the second welding machine 10 through the main traction roller 09, and the two groups of materials 15 are welded together by the second welding machine 10.

[0053] In order to ensure the alignment of the two layers of material 15, the stacking conveyor line 05 is provided with a first deflection correcting guide frame 054 and a first deflection correcting sensor 055 near the main traction roller 09. After the first deflection correcting sensor 055 detects the deviation of the material 15, the conveying angle of the material 15 is corrected by the first deflection correcting guide frame 054; the material transfer conveyor frame 06 is provided with a second deflection correcting guide frame 064 and a second deflection correcting sensor 065 near the main traction roller 09. After the second deflection correcting sensor 065 detects the deviation of the material 15, the conveying angle of the material 15 is corrected by the second deflection correcting guide frame 064, thereby correcting the material 15 output by the first unwinder a and the second unwinder b to ensure the overlapping accuracy of the two layers of material 15 when they are conveyed to the main traction roller 09.

[0054] The first deflection correcting and guiding frame 054 and the second deflection correcting and guiding frame 064 used in the present embodiment are both large deflection correcting and guiding frames with a roller length of 1800 mm.

[0055] The second welding machine 10, the punching and slitting station 11, the multi-strip integration mechanism 12, the third welding machine 13 and the cross-cutting material receiving equipment 14 are arranged in sequence on the rear side of the main traction roller 09, and are used for welding, punching and longitudinal slitting, lamination, welding, cross-cutting and unloading respectively.

The punching and slitting station 11 includes a second punching machine 111 and a slitting machine 112. The slitting machine 112 includes a slitting knife 1121 and a slitting traction roller 1122. The slitting knife 1121 is arranged between the second punching machine 111 and the slitting traction roller 1122.

[0057] In this embodiment, the punching machine is equipped with six rows of punches along the width direction of the material 15, and the slitting knife 1121 is equipped with seven rows of blades along the width direction of the material 15. The slitting knife 1121 is fixedly installed above the conveying path of the material 15, so that the material 15 can be cut into eight strips of material 15 by the slitting knife 1121, among which the six central strips of material 15 have the same width, and the two edge strips of material 15 have different widths according to the different conveying offset errors.

[0058] During operation, the material 15 welded by the second welding machine 10 is punched by the second punching machine 111 , and the punched material 15 is cut into strips by the slitting knife 1121 , and finally transported to the multiple-strip integration mechanism 12 by the slitting traction roller 1122 .

[0059] In order to improve the accuracy of punching and striping, a third deflection correction guide frame 1131 and a third deflection correction sensor 1132 are provided between the second welding machine 10 and the second punching machine 111. After the third deflection correction sensor 1132 detects the deviation of the material 15, the third deflection correction guide frame 1131 corrects the conveying angle of the material 15; a fourth deflection correction guide frame 1133 and a fourth deflection correction sensor 1134 are provided between the second punching machine 111 and the slitting machine 112. After the fourth deflection correction sensor 1134 detects the deviation of the material 15, the fourth deflection correction guide frame 1133 corrects the conveying angle of the material 15. In order to ensure uniform striping width, the third deflection correction guide frame 1131 of this embodiment is a large deflection correction guide frame with a roller length of 1800 mm.

[0060] The multiple-strips-in-one mechanism 12 is disposed between the punching and slitting station 11 and the third welding machine 13 , and is used for stacking the stripped material 15 and conveying it to the third welding machine 13 .

[0062] In this embodiment, the multiple integrated mechanisms 12 also include multiple edge material composite lines d arranged outside the multiple product composite lines c, the diversion module 121 is arranged upstream of the edge material composite line d, and the downstream of the edge material composite line d is correspondingly arranged on the front side of the composite traction roller 125; the edge material composite line d includes multiple fifth rollers 122 arranged in sequence.

[0063] Specifically, the multiple-strips-in-one mechanism 12 includes six product composite lines c and two edge material composite lines d arranged in parallel with each other, and the two edge material composite lines d are respectively arranged above and below the six product composite lines c. The buffer zone 1221 includes a plurality of rollers of different heights to distribute the multiple strips of material 15 to different heights. The rear side of the buffer zone 1221 is provided with eight diverter rollers 1222 and seven groups of steering rollers 1223 of different heights. The eight diverter rollers 1222 correspond one-to-one to the eight strips of material 15, and the seven groups of steering rollers 1223 correspond one-to-one to seven of the diverter rollers 1222.

[0064] The steering rollers 1223 at the same height form a group, and the steering rollers 1223 are used to turn the seven materials 15 so that the eight materials 15 are in the same processing plane.

In this embodiment, the deflection correction actuator 123 of each product composite line c is equipped with a deflection correction guide frame with a roller length of 300 mm to ensure stacking accuracy.

[0066] During operation, the eight strips of material 15 are passed through the buffer zone 1221 and then wound around the corresponding diverter rollers 1222 in sequence. After that, one of the materials 15 is wound around the corresponding fifth roller 122, and the other seven materials 15 are turned through the corresponding steering rollers 1223 and then wound around the corresponding fifth rollers 122; the material 15 located on the product composite line c is sequentially conveyed to the composite traction roller 125 after bypassing multiple fifth rollers 122, the deviation correction actuator 123 and the tension roller 124, and the material 15 located on the edge material composite line d is sequentially conveyed to the composite traction roller 125 after bypassing multiple fifth rollers 122; finally, the six materials 15 located on the product composite line c are stacked up and down in sequence, and the uppermost layer and the lowermost layer are the materials 15 of the edge material composite line d respectively, and the eight layers of materials 15 are conveyed to the third welding machine 13 through the composite traction roller 125, and the eight materials 15 are welded together by the third welding machine 13.

[0067] The cross-cutting material receiving device 14 is arranged at the discharging end of the third welding machine 13, so as to cut the multiple combined materials 15 and discharge them into finished products.

[0068] like Fig.10 As shown, the cross-cutting material receiving device 14 includes a transmission module 141 and a cross-cutting machine 142. The transmission module 141 is arranged corresponding to the discharge end of the third welding machine 13 to convey the material 15 to the cross-cutting machine 142. The cross-cutting machine 142 is arranged downstream of the transmission module 141 to cut the material 15.

[0069] In this embodiment, the transmission module 141 includes a sixth roller 1411, a tension adjustment mechanism 1412 and a cross-cutting traction roller 1413. The tension adjustment mechanism 1412 is movably arranged between the sixth roller 1411 and the cross-cutting traction roller 1413 to adjust the tension of the material 15 during the conveying process. The cross-cutting machine 142 includes a cutting seat 1421, a material pressing cylinder 1422, a cross-cutting knife 1423 and a detection module 1424.

In order to facilitate material removal, a material removal guide plate 1425 corresponding to the material removal port of the cross-cutting machine 142 is provided behind the cutting knife to facilitate manual material removal.

[0070] During operation, multiple combined materials 15 pass through the sixth roller 1411 and the tension adjustment mechanism 1412 in turn, and are transported to the cross-cutting machine 142 through the cross-cutting traction roller 1413. The material 15 passes over the cutting seat 1421 and passes through the pressure cylinder 1422, the cross-cutting knife 1423 and the bottom of the detection module 1424 in turn. When the detection module 1424 detects that the material 15 passing below has reached a preset length, the pressure cylinder 1422 presses down to fix the material 15 on the cutting seat 1421, and then the cross-cutting knife 1423 moves down, and the cross-cutting knife 1423 and the preset blade of the cutting seat 1421 are interlaced to cut the material 15, and finally the product production is completed; finally, the cut material 15, i.e. the product, is transferred to the unloading port of the cross-cutting machine 142 through the unloading guide plate 1425, and the product can be taken away manually.

[0071] The products processed by this equipment can be used for the production and processing of air mattresses, that is, this product is used as a side component of an air mattress, and multiple products of different sizes need to be welded together to produce an air mattress.

[0072] During the production preparation stage, the automated production equipment in this embodiment needs to manually pull the material 15 to each pulling roller and equipment. After the material 15 flows normally, it is only necessary to set a manual loading point at the unwinding station 01 and a manual unloading point at the unloading port of the cross-cutting machine 142. The remaining intermediate production processes can be automated through this equipment, reducing manual participation and improving production efficiency.
