[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0029] like Figures 1 to 6 The figure shows a specific embodiment of the film roll automatic packaging line of the present invention, wherein the film roll automatic packaging line comprises: a material unloading and conveying unit 1, a pallet return unit 2, a film roll automatic unloading unit 3, an automatic card board plugging unit 4, a strapping and packing unit 5, a robot sorting and stacking unit 6, a stacking conveying unit 7, and a post-process packaging unit 8.

[0030] like Figure 2 As shown, the unloading conveying unit 1 includes an unloading double-speed chain conveyor line 101, a film roll tray 102, and a weighing detection unit 104. The film roll tray 102 is used to hold the film roll 106 to be packaged. The film roll tray 102 is arranged on the unloading double-speed chain conveyor line 101. The unloading double-speed chain conveyor line 101 is used to convey the film roll tray 102 to the film roll automatic unloading unit 3. The weighing detection unit 104 is located on one side of the unloading double-speed chain conveyor line 101, and is used to detect the weight of the film roll 106 to be packaged.

[0031] In this embodiment, the unloading and conveying unit 1 includes two parallel first unloading double-speed chain conveyor lines and a second unloading double-speed chain conveyor line perpendicular to the first unloading double-speed chain conveyor lines. The two first unloading double-speed chain conveyor lines are located on both sides of the slitting machine. The film roll can be automatically placed on the film roll tray on the first unloading double-speed chain conveyor line after being unloaded by the slitting machine. The ends of the two first unloading double-speed chain conveyor lines are connected by an angle double-speed chain conveyor line 103 with an unloading rotating mechanism. The unloading rotating mechanism is used to drive the angle double-speed chain conveyor line 103 to rotate ninety degrees to connect the first unloading double-speed chain conveyor line and the second unloading double-speed chain conveyor line. Figure 2 The corner double-speed chain conveyor line 103 is shown to be in a state of docking with the first unloading double-speed chain conveyor line. When the film roll tray transports the film roll to the corner double-speed chain conveyor line 103, the unloading rotating mechanism rotates the corner double-speed chain conveyor line together with the film roll tray and the film roll thereon by 90 degrees, so that the corner double-speed chain conveyor line docks with the second unloading double-speed chain conveyor line to realize an L-shaped conveying route for the film roll tray and the film roll. The corner double-speed chain conveyor line 103 serves to reflux the two first unloading double-speed chain conveyor lines and control the direction of the film roll.

[0032] The unloading and conveying unit includes a manual rework loading station 105, which is located at the head end of the unloading double-speed chain conveyor line and is used to manually feed the repaired abnormal film roll into the unloading double-speed chain conveyor line when the unloading double-speed chain conveyor line is idle.

[0033] The pallet reflow unit includes a reflow double-speed chain conveyor line 107 and two pallet lifting mechanisms. The reflow double-speed chain conveyor line 107 is located directly below the unloading double-speed chain conveyor line 101. The two pallet lifting mechanisms are located at both ends of the unloading double-speed chain conveyor line 101. The pallet lifting mechanism 202 located at the end of the unloading double-speed chain conveyor line is used to receive the film roll pallet located at the end of the unloading double-speed chain conveyor line and descend and send it to the reflow double-speed chain conveyor line 107 located on the lower layer. The pallet lifting mechanism 201 located at the head end of the unloading double-speed chain conveyor line is used to receive the film roll pallet 107 from the reflow double-speed chain conveyor line and ascend and send it to the unloading double-speed chain conveyor line 101 located on the upper layer, so as to facilitate the recycling of the film roll pallet.

[0034] The unloading conveying unit 1 and the pallet return unit 2 of the present invention solve the problem that manual handling is time-consuming and labor-intensive and is prone to damage to products. The surface of the film roll pallet can be covered with soft materials to reduce damage to the product when the film roll contacts the pallet, and the film roll is transported instead of manually pushing a trolley, which reduces the labor intensity and realizes the recycling of the film roll pallet. The unloading double-speed chain conveyor line and the return double-speed chain conveyor line can be made into a single-layer return line, which occupies a larger area.

[0035] like Figure 3 As shown, the automatic film roll unloading unit 3 includes a first film roll gripper and a second film roll gripper. The first film roll gripper is used to grab the film roll to be packaged on the film roll pallet at the end of the unloading double-speed chain conveyor line and place it in the automatic card board plug unit 4. The second film roll gripper is used to grab the film roll with the card board plug in the automatic card board plug unit 4 and place it in the strapping and packing unit 5.

[0036] In this embodiment, the film roll automatic unloading unit 3 includes a double-headed truss 301 and a support frame 303. The double-headed truss 301 is installed at both ends of the support frame 303. The film roll gripper 302 is installed on the double-headed truss 301. The double-headed truss has freedom in the X direction and the Z direction, which is used to realize the descending grabbing action, the descending and lowering action, and the horizontal movement action. The film roll gripper 302 has two gripping pieces spaced at a certain distance. The distance between the two gripping pieces can be adjusted to adapt to film rolls of different widths. The film roll gripper moves with the double-headed truss in the X and Z directions to move horizontally and rise and fall.

[0037] like Figure 3As shown, the automatic pallet plugging unit 4 includes a film roll positioning platform 404 and two pallet plugging robots 401. Each pallet plugging robot 401 is equipped with a pallet plug gripper 402 and a pallet plug feeding mechanism 403. The film roll positioning platform 404 is located below the film roll automatic unloading unit 3. The first film roll gripper places the film roll to be packaged on the film roll positioning platform 404. The two pallet plugging robots 401 are respectively located on both sides of the film roll positioning platform 404. Each pallet plugging robot 401 inserts a pallet plug into the corresponding end of the film roll through the corresponding pallet plug gripper 402.

[0038] In this embodiment, the pallet plug feeding mechanism 403 is a double-layer feeding mechanism. It has two layers of material bins, which can store as many pallet plugs as possible while reducing its floor space as much as possible, leaving space for other process equipment.

[0039] The present invention replaces the manual work of installing the cardboard plug by the cooperation between the automatic film roll unloading unit 3 and the automatic cardboard plug unit 4, thereby greatly reducing the manual participation.

[0040] like Figure 4 As shown, the strapping and packing unit 5 includes a pre-stripping conveying roller 501, an automatic strapping machine 502, a manual box-covering roller 503, a box-turning roller 504, a straight box sealing machine 506, and a four-corner box sealing machine 508, which are arranged in sequence. The second film roll gripper places the film roll with the cardboard plug on the pre-stripping conveying roller 501, the automatic strapping machine 502 is used to strap the film roll with the cardboard plug in the width direction to bundle the film roll and the cardboard plug, and the manual box-covering roller 503 is used to The film roll is loaded into the packaging box with the opening facing downwards manually. Since the length and size of the film rolls produced at the same time vary greatly, manual unpacking is adopted to save costs. The box body after manual unpacking is reversed on the nylon film roll to solve the problem that the gap between the two sides of the nylon film roll and the box is small and it is difficult to put it directly into the box. The box turning roller 504 is used to rotate 180° when the film roll arrives so that the opening of the packaging box with the film roll faces upwards. The straight box sealing machine 506 is used for straight box sealing, and the four-corner box sealing machine 508 is used for four-corner box sealing. The box turning roller 504 is connected to the straight box sealing machine 506 through the horizontal transmission roller 505, and the straight box sealing machine 506 is connected to the four-corner box sealing machine 508 through the steering roller 507.

[0041] In this embodiment, the conveying roller 501 before strapping is provided with a limiting clamp 510, and the limiting clamp 510 is used to accommodate the film roll with the pallet plug in the width direction of the film roll to prevent the pallet plug from collapsing and deforming in an eight-shaped shape due to the pressure of the film roll's own weight. After the automatic strapping machine puts on the PP tape, the film roll and the pallet plug are limited, and no clamping assistance is required; the box turning roller 504 has a clamping mechanism, and the clamping mechanism is used to clamp the film roll after being put on the box.

[0042] In this embodiment, the width direction of the film roll in the film roll positioning platform 404 is parallel to the conveying direction of the second unloading double-speed chain conveyor line and the film roll positioning platform 404 is located at the end of the second unloading double-speed chain conveyor line, and the conveying directions of the pre-strapping conveying roller 501, the automatic strapping machine 502, the manual box-putting roller 503, and the box-turning roller 504 in the strapping and box-packing unit 5 are perpendicular to the conveying direction of the second unloading double-speed chain conveyor line, and at the same time are perpendicular to the conveying direction of the one-line carton sealing machine 506, and parallel to the conveying direction of the four-corner carton sealing machine 508.

[0043] The present invention realizes fast and simple packing of film rolls through the strapping and packing unit 5, thereby improving the success rate and speed of packing.

[0044] like Figure 5 As shown, the robot sorting and palletizing unit 6 includes a palletizing robot grabbing roller 601, a palletizing robot 602, a palletizing robot seventh axis 603, and a box gripper 604. The palletizing robot grabbing roller 601 is located between the four-corner carton sealing machine and the palletizing robot. The palletizing robot seventh axis 603 is used to move the palletizing robot 602 to expand the coverage of the palletizing robot. The palletizing robot 602 sorts and palletizes film rolls of different specifications through the box gripper 604 to achieve multi-station sorting and palletizing. The box gripper grabs the finished box and can cooperate with the robot to realize the upright placement of the box to prevent the product from being compressed.

[0045] The packaging line includes a control system, an RFID chip is arranged on the film roll tray 102, the unloading and conveying unit includes an RFID reader / writer for reading the RFID chip of the film roll tray 102, and the control system is used to write the detected weight of the film roll into the RFID and obtain the film roll information, so as to facilitate the tracking and maintenance of the film roll information, and at the same time control the stacking robot 602 to automatically stack the film rolls on the workstations of corresponding specifications.

[0046] The stack conveying unit 7 is used to convey the stack to the downstream packaging unit after the stack is full. In this embodiment, the stack conveying unit 7 is an AGV conveying unit. The AGV conveying unit can also be a roller conveyor for direct conveying, but in this way, a large number of rollers are required for 14 workstations, which will greatly increase the cost and occupy a huge space.

[0047] like Figure 6 As shown, the back-end packaging unit 8 is used to tape and wrap the stack, and the back-end packaging unit includes a connecting roller 801, a tic-tac-toe tape machine 802, a film wrapping machine 803, and a marking machine 805 arranged in sequence. Since the stacking cycle is slow, two or three nylon film packaging lines can share a set of tape and film wrapping units to complete the film wrapping of the stack, saving equipment and cost.

[0048] The film roll automatic packaging line of the present invention is particularly suitable for nylon film packaging line. The film roll is nylon film, which is cut into several small rolls of different specifications by a slitting machine. The slitting machine can unload up to 14 rolls at a time, i.e., 14 different specifications. The 14 different specifications need to be packaged in cartons of different sizes and stacked in different positions. The above purpose can be achieved by the film roll automatic packaging line of the present invention. The specific working process is as follows:

[0049] The slitting machine unloads automatically. When unloading, the swing arm automatically places the nylon film roll on the film roll tray 102 of the unloading conveying unit 1. When all the film rolls are unloaded, the unloading double-speed chain conveyor line 101 is transported forward to the corner double-speed chain conveyor line 103. If there are film rolls with quality problems, they are manually unloaded here. Normal film rolls pass through the corner double-speed chain conveyor line 103 in turn, and enter the weighing detection unit 104 for weighing. The system automatically writes the weight information into the RFID. The film roll tray continues to be transported to the unloading station of the automatic unloading unit 3 of the film roll, and is unloaded by the automatic unloading unit 3 of the film roll. The empty pallet is refluxed along the reflux double-speed chain conveyor line through the pallet reflux unit 2, and is sent to the downstream double-speed chain conveyor line again by the pallet lifting mechanism. When the production line is idle, the repaired nylon film can be put back online through the manual rework line station;

[0050] The automatic film roll unloading unit 3 grabs the film roll from the film roll tray 102 of the unloading conveying unit 1 through the film roll gripper of the double-headed truss. The inner core of the film roll is hollow. The film roll gripper lifts the film roll from the roll core and places it on the film roll positioning platform 404 of the automatic loading card board plug unit 4 for positioning. The card board plug robot 401 grabs the card board plug from the card board plug feeding mechanism 403 through the card board plug gripper 402 and installs it on the nylon film roll from both ends. The card board plug feeding mechanism 403 then automatically pushes a card board plug forward; the automatic film roll unloading unit 3 grabs the nylon film roll with the card board plug from the film roll positioning platform 404 through the film roll gripper on the other head of the double-headed truss and places it on the front conveying roller 501 of the tape packing unit 5. When the automatic film roll unloading unit 3 is placed on the roller and the gripper has not been released, the front conveying roller 501 passes through the limiting clamping plate 510 The nylon film roll is limited on both sides to prevent the pallet from deforming. At the same time, it is sent to the automatic strapping machine 502. After the automatic strapping machine 502 puts two PP tapes on it, the nylon film roll and the pallet plug are limited, and no clamping assistance is required. It moves forward to the manual box roller 503. Since the length and size of the film rolls produced at the same time vary a lot, manual unpacking is adopted to save costs. The box body after unpacking is manually buckled on the nylon film roll, which solves the problem that the gap between the two sides of the nylon film roll and the box is too small and it is difficult to put the nylon film roll directly into the box. Then, the box is turned 180 degrees by the box turning roller 504. When turning, the box turning roller 504 will limit the film roll and the box. After packing, the film roll passes through the horizontal conveying roller 505 in turn through the one-line box sealing machine 506 to complete the one-line box sealing on the upper surface, and then passes through the steering roller 507 and the four-corner box sealing machine 508 to complete the overall I-shaped box sealing effect.

[0051] The boxed products enter the robot grabbing roller 601 of the robot sorting and palletizing unit 6 and are positioned, waiting to be grabbed by the palletizing robot 602. The palletizing robot 602 and the control system obtain product specification information. The palletizing robot 602 grabs the box through the box gripper 604 and moves to the designated palletizing station through the seventh axis 603 of the palletizing robot for palletizing.

[0052] When a stack is full, the control system calls the AGV of the AGV conveying unit through the AGV scheduling system to pick up the stack. The AGV picks up the full stack of products and goes to the downstream packaging unit 8, places it on the connecting roller 801, and the roller conveys the stack through the tic-tac-toe taping machine 802, the film wrapping machine 803 and the labeling machine 804 in sequence. After completing the operations of tic-tac-toe taping, wrapping plastic film, and affixing stack labels, it waits on the other end roller 801 for manual unloading to complete the automatic packaging process.

[0053] The automatic film roll packaging line of the present invention replaces manual unloading and conveying with automatic unloading, which facilitates product boxing and reduces equipment costs as much as possible. The equipment is arranged in a smaller and narrower space to save equipment costs as much as possible.

[0054] In this specification, the present invention has been described with reference to specific embodiments thereof. However, it is apparent that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the description should be regarded as illustrative rather than restrictive.
