DETAILED DESCRIPTION

[0023] The following is a more detailed description of the implementation of the utility model in conjunction with the drawings and the figure marks, so that those skilled in the art can implement it after reading this specification. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0024] The utility model provides Figure 1-6The roll paper packaging system shown in the figure comprises a longitudinal conveying device 10, a steering conveying device 20, a transverse conveying device 30, a vertical conveyor 40, a flat conveyor 50 and a control system which are arranged in sequence. The roll paper is a cylindrical structure. When the utility model is used, the roll paper can first enter the longitudinal conveying device 10, with its side facing down in a lying state, and be transported by the chain plate conveyor and complete weighing, diameter detection, and label pasting in sequence, and then be sent to the transverse conveying device 30 by the steering conveying device 20 to complete film wrapping, and the vertical conveyor 40 changes the posture of the roll paper from side facing down to bottom facing down, and transfers it to the flat conveyor 50 for temporary parking, and finally transfers it to the warehouse by a forklift.

[0025] The longitudinal conveying device 10 includes a plurality of chain conveyors 11 arranged in sequence along the length direction, and a weighing device, a diameter detection device 12 and a label pasting device 13 arranged in sequence along the length direction of the chain conveyor 11. The chain conveyor, the weighing device, the diameter detection device 12 and the label pasting device 13 are all electrically connected to the control system. The web is conveyed by the chain conveyor 11, and weighing and diameter detection are completed in sequence. The label pasting device 13 then prints the weight, diameter and other data on the label paper and pastes it on the surface of the web.

[0026] The chain conveyor 11 can adopt a V-shaped chain conveyor to support the paper roll in a lying state to prevent the paper roll from rolling during transportation. Multiple chain conveyors 11 are connected in sequence, and adjusting the conveying speed difference of multiple conveyors can play a buffering role. Position sensors 111 electrically connected to the control system are provided at both ends of the chain conveyor 11 to determine the position of the paper roll; the position sensor 111 can adopt a photoelectric sensor to detect the signal change generated when the paper roll passes through the position sensor 111 to detect the position of the paper roll, and transmit the position signal to the control system. The weighing device includes a weighing sensor arranged at the bottom of a chain conveyor 11, and the weighing sensor is electrically connected to the control system. After the paper roll is conveyed to this chain conveyor 11, weighing is completed and the weight data is transmitted to the control system. The diameter detection device 12 includes a detection bracket 121 across the chain conveyor 11. The detection bracket 121 is provided with an ultrasonic diameter gauge 122. The ultrasonic diameter gauge 122 is electrically connected to the control system. After the web passes through the detection bracket 121, the ultrasonic diameter gauge 122 transmits its diameter data to the control system.

[0027] The label pasting device 13 includes a printing device 131, a gluing device 132 and a mechanical arm 133 for transferring labels, which are arranged on one side of the chain conveyor 11. The printing device 131 can be a printer, and a paper receiving tray 1311 is arranged on the side facing the gluing device 132. The control system transmits the weight, diameter and other data to the printing device 131, and the printing device 131 prints it on the label paper. The mechanical arm 133 can be an IRB-4600 industrial robot, and a label suction cup 1331 is arranged at the end thereof to absorb the label paper. The mechanical arm 133 is arranged between the paper receiving tray 1311, the gluing device 132 and a chain conveyor 11, so that the working range of the mechanical arm 133 covers the above three. Its working process is: firstly, the label paper is absorbed from the paper receiving tray 1311, then the label paper is transferred to the gluing device 132 and the back of the label paper is glued, then the label paper is pasted on the roll paper conveyed by the chain conveyor 11, and finally reset.

[0028] The gluing device 132 includes a glue tray 1321, an active gluing roller 1322, a driven gluing roller 1323 and an intermediate gluing roller 1324 which are rotatably connected to the glue tray 1321, and a gluing motor which drives the active gluing roller 1322 to rotate. The intermediate gluing roller 1324 and the driven gluing roller 1323 are both connected to the active gluing roller 1322 by transmission. Specifically, the driven gluing roller 1323 is connected to the active gluing roller 1322 by gear transmission, and the two rotate in opposite directions. The intermediate gluing roller 1324 is arranged between the active gluing roller 1322 and the driven gluing roller 1323, and a gap is arranged between the intermediate gluing roller 1324 and the active gluing roller 1322 and the driven gluing roller 1323, and the gap is 1 to 3 mm.

[0029] The glue can be a gelatinized liquid made of starch, calcium carbonate, and sodium carboxymethyl cellulose (CMC), which is placed in a glue tray 1321 and submerged in the bottom of the active glue roller 1322 and the driven glue roller 1323. The active and driven glue rollers are arranged as follows: Figure 4 When the glue sticking to the surface is rotated in the direction shown, the glue sticking to the surface is brought upward, and the glue on the surface is smoothed by the middle glue roller 1324 to ensure uniform glue thickness, and the excess glue sticks to the surface of the central glue roller. Furthermore, the active glue roller 1322, the middle glue roller 1324, and the driven glue roller 1323 are all tangent to the same plane, please refer to Figure 4 When gluing, the mechanical arm 133 makes the back of the label paper tangent to the three gluing rollers, and the three gluing rollers rotate to apply glue to the tangent position.

[0030] Due to the limitation of the site, the whole packaging system is arranged in an L shape, and the web is diverted from the longitudinal conveying device 10 to the transverse conveying device 30 by the diverting conveying device 20. The diverting conveying device 20 includes a rotatable turntable 21, a chain plate conveyor 11 arranged on the turntable 21, and a rotating motor driving the turntable 21 to rotate. The diverting conveying device 20 first aligns its chain plate conveyor with the longitudinal conveying device 10. After the web enters the diverting conveying device 20, the turntable 21 rotates 90 degrees to align its chain plate conveyor with the transverse conveying device 30, and then the web is fed into the transverse conveying device 30.

[0031] The transverse conveying device 30 includes a chain conveyor 11 and a film wrapping device, and the film wrapping device includes a driving roller 31 and a driven roller 32 respectively arranged on both sides of the chain conveyor 11, a motor driving the driving roller 31 to rotate, and a film wrapping machine 33 for film wrapping. A lifting device is arranged at the bottom of the driving roller 31 and the driven roller 32, and the lifting device can be a cylinder, and the distance between the driving roller 31 and the driven roller 32 is less than the diameter of the web. The film wrapping machine 33 can be a fully automatic radial film wrapping machine.

[0032] After the web enters the transverse conveying device 30, the lifting device drives the active and driven rollers to rise and lift the web, and the film wrapping machine 33 fixes the packaging film on the web. The active roller drives the web and the driven gear to rotate, so that the packaging film is wrapped around the surface of the web. After the film wrapping is completed, the lifting device descends, and the web returns to the chain conveyor and is conveyed to the vertical conveyor 40. The vertical conveyor 40 can refer to the relevant technology and is used to change the posture of the web from side-down to bottom-down, such as Figure 6 As shown, the roll paper is temporarily parked on the flat conveyor 50 so that the bottom surface of the roll paper contacts the flat conveyor 50 to prevent rolling. The flat conveyor 50 is close to the ground, which makes it convenient for a forklift to carry the roll paper away from the flat conveyor 50 and store it in the warehouse.

[0033] The control system includes a host computer, a lower computer and a database electrically connected to the host computer, wherein the lower computer is electrically connected to the longitudinal conveying device 10, the steering conveying device 20, the transverse conveying device 30, the vertical conveyor 40 and the flat conveyor 500. The host computer can be a computer with numerical calculation and logic calculation capabilities, the lower computer can be a programmable logic controller (PLC), and the database is a storage medium. The host computer performs data processing and issues control commands, the database performs data storage, and the lower computer controls each component according to the control commands issued by the host computer.

[0034] The above are one or more embodiments of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
