Description

Technical Field

[0001] This utility model belongs to the field of cotton bag packaging technology, specifically relating to an automated bag making and cotton bag sealing production line. Background Technology

[0002] Currently, the main method in cotton processing involves manually placing pre-made packaging bags over the finished cotton bales, followed by end-face stitching and barcode label sewing to complete the bale sealing process. The most common packaging bags on the market are cotton cloth bags and plastic bags, both pre-made with flat openings. The pre-made bags are manually placed onto a bag-packing machine, and then a pusher pushes the cotton bale out of the machine while simultaneously placing the pre-made bag completely over it. The bale is then weighed on a weighing platform, and a barcode is manually printed. The bale is then sent to a dedicated sewing platform for manual sewing. However, due to manual operation, errors can easily occur at the ends of the pre-made bags, leading to a lower product qualification rate. Furthermore, the bagging process is labor-intensive, time-consuming, and inefficient.

[0003] In my country's existing cotton processing production lines, only the sealing process is done manually. This can be considered the "last mile" of automation in cotton processing at present. Achieving automation in this process is of great significance to the advancement of cotton processing technology in my country.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figure 1 As shown, this utility model discloses an automated bag making and cotton bale sealing production line, including: a bag making device and a cotton bale sealing device, such as... Figure 2 As shown, the bag making device includes: a cloth roll storage mechanism 1, a cloth feeding mechanism 2, a cotton bag double-side sewing mechanism 3, an M-shaped folding and sorting mechanism 4, a cotton cloth tightening mechanism 5, a cotton bag bottom sewing mechanism 6, a cotton bag fixed-length cutting and stacking mechanism 7, and a cotton bag temporary storage mechanism 8, arranged in sequence.

[0028] The fabric roll storage mechanism 1 is a two-roll storage mechanism. The first servo motor 21 of the fabric feeding mechanism 2 drives the roller 22 to rotate, thereby unwinding the two fabric rolls and flattening them before feeding them into the cotton bag double-side sewing mechanism 3. During the first fabric feeding, manual assistance is required to complete the fabric roll feeding and cotton bag double-side sewing operations.

[0029] like Figure 3 As shown, the double-sided sewing mechanism 3 of the cotton bag is located at the front end of the platform of the M-shaped folding and finishing mechanism 4, and includes: a feed roller 31, a first overlock sewing machine 32, a second overlock sewing machine 33, a first excess edge trimming and recovery device 34, a second excess edge trimming and recovery device 35, and a second servo motor 36; the first excess edge trimming and recovery device 34 and the second excess edge trimming and recovery device 35 are respectively set on both sides of the first overlock sewing machine 32 and the second overlock sewing machine 33; the second servo motor 36 is set on one side of the feed roller 31; the fabric roll is fed to the first overlock sewing machine 32 and the second overlock sewing machine 33 on both sides by the feed roller 31, and the two sides of the fabric roll are wirelessly extended and sewn to form a cotton tube shape. The first overlock sewing machine 32 and the second overlock sewing machine 33 are three-thread overlock sewing machines with encoder precision feedback control and are mature existing technologies, which will not be described in detail here.

[0030] The M-shaped folding and finishing mechanism 4 includes: a non-powered disc 41, a shaping bracket 42, and a finishing mechanism platform 43. The finishing mechanism platform 43 is mounted on a frame. The non-powered discs 41 are symmetrically arranged along the central axis of the finishing mechanism platform 43, and each set of non-powered discs 41 is sequentially tightened towards the central axis along the cotton bag production direction. The shaping bracket 42 is located inside the non-powered disc, with two layers of shaping brackets sandwiching the non-powered disc 41. The shaping bracket 42 is inverted U-shaped along the direction of the non-powered disc. The shaping bracket 42 is inserted into the cotton tubular fabric roll, and the non-powered disc 41 is outside the cotton tubular fabric roll. The cotton tubular fabric roll completes the M-shaped folding of the cotton tubular fabric roll by moving along the intersection of the non-powered disc 41 and the inner shaping bracket 42.

[0031] The cotton fabric tightening mechanism 5 includes a first traction roller 51, a tightening mechanism main support 52, a non-powered roller 53, a second traction roller 54, a third servo motor 55, a gravity tensioning roller 56, and a fourth servo motor 57. The tightening mechanism main support 52 is convex in shape. The first traction roller 51 and the third servo motor 55 are set at the front end of the tightening mechanism main support 52. The third servo motor 55 drives the first traction roller 51 to rotate and bring the M-shaped fabric roll into the cotton fabric tightening mechanism 5. The non-powered roller 53 is set on the high plane of the tightening mechanism main support 52. Three non-powered rollers 53 can be set. The gravity tensioning roller 56 is set at the relative position below the non-powered rollers 53. Two gravity tensioning rollers 56 can be set below the middle gap of the three non-powered rollers 53. The M-shaped fabric roll is tightened by the cooperation of the non-powered rollers 53 and the gravity tensioning rollers 56. This part adopts the pulley principle design and uses the gravity of the lower gravity tensioning roller 56 to achieve the tension of the cotton bag. The rear end of the main support frame 52 of the tightening mechanism is equipped with a second traction roller 54 and a fourth servo motor 57. The fourth servo motor 57 drives the second traction roller 54 to rotate and bring the M-shaped fabric roll out of the cotton fabric tightening mechanism and into the bottom sewing mechanism 6 of the cotton bag.

[0032] The cotton bag bottom sewing mechanism 6 clamps the M-shaped fabric roll using its own clamping mechanism, and sews the bottom of the cotton bag using a movable sewing machine. Three different sewing methods can be used: straight edge sewing, beveled sewing, and semi-circular sewing. The cotton bag fixed-length cutting and stacking mechanism 7 clamps the bottom of the cotton bag with a mechanical gripper and drags the cotton fabric roll to a certain length position towards the cotton bag temporary storage platform. The cutting device cuts the cotton fabric roll, with the opening of the cotton bag facing the end of the cotton bag bottom sewing mechanism 6. The completed cotton bags are then stored sequentially in the cotton bag temporary storage mechanism 8.

[0033] In actual production, bag-making devices and cotton bale sealing devices can be rationally installed and laid out within the production line space, reducing on-site installation and modification costs. Bag-making devices can be installed on the production line to work synchronously with the cotton bale sealing devices, or they can be installed in idle workshops or warehouses within the processing plant for separate bag-making operations. The bags can then be neatly arranged for use by the cotton bale sealing devices, significantly saving production line space.

[0034] like Figure 4 As shown, the cotton bale sealing device includes a cotton bag gripping mechanism 9, a cotton bag retrieval mechanism 10, an opening and closing retrieval device 11, a retrieval device sliding mechanism 12, a bag pusher 13, an end face M-shaped closing and finishing mechanism 14, an end face clamping mechanism 15, an end face sewing excess trimming mechanism 16, and a barcode paper sewing mechanism 17. The cotton bag gripping mechanism 9 is set above the cotton bag temporary storage mechanism 8 via a motion track. The cotton bag gripping mechanism 9 uses a robotic arm 91 to drive a rotatable matrix needle suction cup group to complete the cotton bag gripping operation. The lower layer of the cotton bag falls off naturally and is suspended in the air, so that the opening of the cotton bag faces the cotton bag retrieval mechanism 10, which also improves the success rate of the cotton bag retrieval mechanism 10.

[0035] like Figure 5 As shown, the cotton bag taking mechanism 10 consists of two symmetrically arranged parts on the upper and lower end faces of the opening and closing bag taker. The upper end face is equipped with a fifth servo motor 101, an upper bag taking sliding track 102, a sixth servo motor 103, two gripper pads 104, two opening and closing grippers 105, and an upper gripper sliding track 106. The fifth servo motor 101 drives the cotton bag after it is gripped to move along the upper bag taking sliding track 102. The sixth servo motor 103 drives the opening and closing grippers to move along the upper gripper sliding track 106, thereby achieving the gripping or putting down of the cotton bag by moving closer to or away from the gripper pads. The lower end face is the same as the upper end face, therefore, the view of the lower end face is not shown. The lower end face is equipped with a seventh servo motor 107, a lower bag-covering sliding track 108, an eighth servo motor 109, two gripper pads 110, two opening and closing grippers 111, and a lower gripper sliding track 112. The seventh servo motor 107 drives the gripped cotton bag to move along the lower bag-covering sliding track 108; the eighth servo motor 109 drives the opening and closing grippers to move along the lower gripper sliding track 112, thereby gripping or releasing the cotton bag by moving closer to or away from the gripper pads. The four gripper pads and four opening and closing grippers work together to open the cotton bag opening into a rectangular structure. The cotton bag is then placed on the outside of the opening and closing bag-covering device 11. The opening and closing bag-covering device 11 has an automatic opening and closing function. The device is divided into two symmetrical parts, left and right, which are respectively installed on the sliders of the linear guide rail. Powered by the servo motor, it automatically opens to a certain extent to tighten the cotton bag. The opening and closing type bag-covering device 11 is set on the bag-covering device sliding mechanism 12. The bag-covering device sliding mechanism 12 transfers the opening and closing type bag-covering device 11 with the cotton bag covered to the cotton bag covering position. The cotton bag is driven by the bag pusher 13 to pass through the opening and closing type bag-covering device 11 and cover the cotton bag on the outside of the cotton bag.

[0036] like Figure 4 As shown, the M-shaped end-face finishing mechanism 14, the end-face seam excess trimming mechanism 16, the end-face clamping mechanism 15, and the barcode paper sewing mechanism 17 are sequentially arranged along the cotton bag cover. Figure 6As shown, the M-shaped closing and finishing mechanism 14 includes: an M-shaped closing sliding track 141, an M-shaped variable model 142, a cotton bag pressing contact 143, a ninth servo motor 144, a tenth servo motor 145, a follower sliding track 146, an eleventh servo motor 147, and a twelfth servo motor 148. The cotton bag pressing contact 143 is mounted on the frame and uses a built-in cylinder to press the cotton cloth against the surface of the opening and closing bag holder to prevent slippage. The follower sliding track 146 is mounted on the frame. The eleventh servo motor 147 and the twelfth servo motor 148 drive the M-shaped closing and finishing mechanism 143 through synchronous control. The M-shaped closing sliding track 141 and the M-shaped variable model 142 move to the cotton bag covering point to grasp the cotton bag. The tenth servo motor 145 drives the M-shaped closing sliding track 141 and the M-shaped variable model 142 to follow the cotton bag in the front and back direction. The ninth servo motor 144 drives the M-shaped variable model 142 to move along the M-shaped closing sliding track 141. With the cooperation of the four cotton bag pressing tentacles, the M-shaped closing is completed. The M-shaped variable model 142 consists of two sets of symmetrically installed V-shaped mechanisms and four sets of needle suction cups. Each set of needle suction cups is set at both ends of the V-shaped mechanism.

[0037] like Figure 7 As shown, the end-face clamping mechanism 15 includes an upper clamping plate 151, a lower clamping plate 152, a clamping sliding track 153, and a thirteenth servo motor 154. The thirteenth servo motor 154 drives the upper clamping plate 151 and the lower clamping plate 152 to move evenly along the clamping sliding track, thereby clamping the end face of the M-shaped closed bag. At this time, the end-face sewing excess trimming mechanism 16 sews the end face of the M-shaped closed bag and trims off the excess fabric. The end face can be sewn using three different methods: straight edge sewing, chamfered sewing, and semi-circular sewing. The barcode paper sewing mechanism 17 places the printed barcode paper into the barcode temporary storage slot. Two rotary robotic arms of different lengths are driven by servo motors to rotate 270° respectively, sending the two barcode paper temporary storage slots to the designated positions. Then, two semi-circular sewing machines start working, sewing on both ends of the bag, with the sewing positions being centrally symmetrical, thus completing the sewing of the barcode paper. The packaged cotton bales are transported to the next workstation by using the conveying platform 18 located below the end face sewing excess trimming mechanism 16. In actual production, the function of the conveying platform 18 is not limited to transporting cotton bales. By setting up sensors, the position of the cotton bales is accurately located, thereby assisting the end face sewing excess trimming mechanism 16 in completing the operation.
