DETAILED DESCRIPTION

[0037] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0038] refer to Figures 1 to 11

[0039] A device for automatically bagging and labeling paper certificates of conformity comprises a transversely arranged roll material conveying device 10, a fixed frame 20 being installed on the rear side of the roll material conveying device, an industrial printer 30 being installed on the upper end of the fixed frame, a plastic bag discharging mechanism 40 being installed on the lower side of the industrial printer, a blowing mechanism for blowing open the plastic bag opening being provided above the bag outlet 41 of the plastic bag discharging mechanism, a sealing machine 60 for sealing the plastic bag being provided below the bag outlet of the plastic bag discharging mechanism, a glue-applying and tearing mechanism 70 for applying double-sided tape to the plastic bag and tearing off the double-sided tape layer being provided on the lower front side of the sealing machine, and a labeling adsorption mechanism 80 capable of lifting and lowering the plastic bag and moving longitudinally being provided on the lower side of the sealing machine, so as to adsorb the plastic bag containing the certificate of conformity through the labeling adsorption mechanism and affix the plastic bag to the roll material 1.

[0040] In this embodiment, the coil conveyor includes a mounting frame 11, on which discharge rollers 12 are spaced laterally apart. A chain drive mechanism is provided on the mounting frame to drive the discharge rollers, thereby driving the discharge rollers to achieve lateral movement of the coil. The coil conveyor is also provided with a position sensor connected to the power source of the chain drive mechanism, so that the coil conveyor stops when the coil is delivered to its proper position.

[0041] In this embodiment, a pair of cooperating paper drop guides 32 are located on either side of the industrial printer's outlet 31 and on the front side of the mounting bracket. These paper drop guides have a funnel-shaped vertical cross-section and are located above the outlet of the plastic bag dispensing mechanism, allowing the plastic bag to fall more easily into the bag. Consequently, the paper drop guides ensure that the certificate of conformity is reliably and effectively dropped into the opening of the plastic bag, which has been inflated by compressed air.

[0042] In this embodiment, to blow open the plastic-sealed bag, the blowing mechanism includes an air inlet pipe 51. A vertically downward-facing air outlet 52, connected to the air inlet pipe and shaped like a long slot, is located above the outlet of the plastic-sealed bag. The air inlet pipe is connected to a compressed air source to deliver compressed air to open the bag and prepare the A4 certificate.

[0043] In this embodiment, the lower end of the plastic bag is sealed, and the upper side 4 of the bag opening 3 of the plastic bag 2 is connected to the bottom of the previous plastic bag in a point-disconnected manner. The other side 5 of the bag opening of the plastic bag is not connected to the bottom of the previous plastic bag, so that the bag opening can be blown open by the blowing mechanism so that the certificate of conformity can fall into the plastic bag. Figure 10 .

[0044] In this embodiment, to seal the opening of the plastic-sealed bag, the sealing machine includes an inverted ridge-shaped mounting frame 61, which is connected to a fixed frame and forms a channel 62 through which the plastic-sealed bag passes. A retractable electric hot ironing rod 63 is mounted on the inverted ridge-shaped mounting frame, which presses longitudinally against the plastic-sealed bag to heat-shrink the bag's opening. The retractable electric hot ironing rod is driven by a longitudinal cylinder 65 to achieve retractable pressing. Longitudinal guide rods slidably connected to the inverted ridge-shaped mounting frame are fixed on both sides of the retractable electric hot ironing rod. Bag drop guides 64 are located on either side below the bag outlet of the plastic-sealed bag outlet mechanism. These guides are located within the channel and fixed to the front side of the fixed frame, allowing the bag to drop into the labeling and suction mechanism through the guides. The retractable electric hot ironing rod is positioned between the bag drop guide and the paper drop guide.

[0045] In this embodiment, to allow the plastic packaging bag to be attached to the roll material, the adhesive layer application and removal mechanism includes a pair of longitudinal linear slides 71. A vertical linear slide 72 is connected between the slides of the pair of longitudinal linear slides via a fixed plate 78. A chassis 73 is mounted on the slide of the vertical linear slide. A reel 74 for mounting a double-sided film roll is disposed transversely at the lower portion of the chassis. A pressure roller 75 is rotatably mounted above the rear side of the reel. A guide roller 76 is mounted above the front side of the pressure roller. A double-sided film layer reel 77 is also mounted in front of the guide roller, which is driven by a motor or other power component to rotate. This allows the double-sided film layer to be reeled up.

[0046] The pressure roller 75 is pressed against the fixed frame by the longitudinal linear slide 71 so that the double-sided tape can be attached to the plastic bag; at the same time, the chassis is moved downward by the vertical linear slide 72 to vertically attach the double-sided tape to the plastic bag, and the double-sided tape is attached tightly in conjunction with the pressure roller. The lower part of the plastic bag has an exhaust hole so that the gas in the plastic bag can be discharged when the pressure roller moves downward. At the same time, the bag mouth of the plastic bag is also sealed. In order to better achieve the gluing, the double-sided tape layer 6 is arranged on the double-sided tape layer 7 in sections of fixed length. The structure is as follows Figure 11 shown.

[0047] In this embodiment, the labeling adsorption mechanism includes a first screw mechanism 81 longitudinally arranged on one side of the fixed frame and connected to the roll material conveying device at one end. A second screw mechanism 82 is vertically installed on the slider of the first screw mechanism, and a mounting plate 83 is horizontally fixed on the slider of the second screw mechanism. A labeling adsorption plate 84 is vertically fixed on the cantilever end of the mounting plate.

[0048] In this embodiment, the first and second screw mechanisms each include a screw at each end rotatably connected to the frame, each screw being driven by a servo motor to rotate and advance in a longitudinal or vertical direction. A slider is threaded onto the screw, and guide rods are provided on either side of the screw, each slidably connected to the slider. The first and second screw mechanisms can also each be a linear slide mechanism.

[0049] In this embodiment, a clearance cavity 21 for the labeling plate is provided at the bottom of the fixing frame to allow for movement of the mounting plate. The labeling plate is a vacuum-pressure soft adhesive plate with evenly distributed vacuum holes 85. The plate is connected to the negative pressure mechanism via a pipeline to prevent the bagged certificate from falling to the ground.

[0050] In this embodiment, the cantilever end of the mounting plate is connected to the labeling suction plate via a longitudinally arranged connecting plate 89. A vertical cylinder 86 hinged to the base shell connecting plate is provided on the rear side of the labeling suction plate. A protective support plate 87 is provided on the lower side of the labeling suction plate. The middle portion of the protective support plate is hinged to a hinged seat fixed to the rear side of the lower end of the labeling suction plate. The rear end of the protective support plate is hinged to the telescopic rod of the vertical cylinder. The front end of the protective support plate has a hook portion 88 that turns upward. Therefore, before the plastic-sealed bag falls, the telescopic rod of the vertical cylinder is extended to make the protective support plate horizontal so as to support the lower end of the plastic-sealed bag and prevent the plastic-sealed bag from shifting. After the labeling suction plate absorbs the plastic-sealed bag, the telescopic rod of the vertical cylinder is retracted to make the protective support plate vertical to avoid interference when the labeling suction plate is labeling.

[0051] This automatic paper certificate bagging and labeling system features a digital web information management system (MES). It connects to an industrial printer via a PROFINET network, pushing certificate information and providing automatic start and stop signals for the printer to automatically print the certificate. The weighing system connects to the S7-300 industrial primary network of the web packaging unit, which is used for web packaging, via a secondary PROFINET network. This system communicates the dimensions of the web and the material rack, as well as the location of the web. The S7-200 automatic bagging and labeling system automatically positions the certificate on the web surface and applies the label. The primary network is primarily managed by the S7-200 programmable controller.

[0052] Working principle:

[0053] 1. The conjoined plastic-sealed bag is discharged from the bag outlet of the plastic-sealed bag discharging mechanism and then transported to the bagging position. At this time, the air blowing port blows air into the bag to open it up and receive the A4 certificate.

[0054] 2. After receiving the print command, the industrial printer automatically prints the certificate on A4 paper. The printed certificate A4 paper slides down the paper guide from the outlet into the expanded bag;

[0055] 3. After the certificate of conformity falls into the plastic bag, the bag outlet continues to output the plastic bag downward to the sealing machine. The sealing plate presses against the bag to expel the air inside, while the sealing rod seals the bag. At the same time, the rubber tearing roller starts to tear off the double-sided rubber on the surface of the plastic bag.

[0056] 4. After the plastic bag is sealed, the bag outlet continues to output the plastic bag down the bag drop guide groove to the labeling suction plate located on the lower side of the bag drop guide groove. The labeling suction plate catches the plastic bag.

[0057] 5. Since the coils are divided into horizontal and vertical packages, the sizes of the coils are uneven, and the labeling positions can be uniformly managed. ① For coils with a height of 1.5-2.1 meters, the labeling position is unified at 1.5 meters; ② For coils with a height of 0.8-1.5 meters, the labeling position is unified at 0.8 meters; ③ For coils with a height of less than 0.8 meters, the labeling position is unified at 0.1 meters below the highest point.

[0058] 6. The plastic bag containing the certificate of conformity is placed on the labeling plate and pushed longitudinally toward the web by the first screw mechanism. Once the longitudinal position is achieved, the labeling plate is positioned vertically by the second screw mechanism. The position of the certificate of conformity is accurately determined based on the dimensions and position of the web and in conjunction with the position sensor on the labeling plate. The air cylinder then pushes the labeling plate toward the web to attach the certificate of conformity without damaging the web.

[0059] In this embodiment, the labeling position is determined by a first screw mechanism, which uses a position encoder and the web's diameter to calculate the labeling position. A servo motor then moves the labeling plate closer to the web. A second screw mechanism, in a vertical direction, then calculates the web's height using a position encoder. This is achieved through positioning along both horizontal and vertical axes. Photoelectric limiters control the positioning process, determine the number of certificates dropped, and ensure that the labeling plate does not damage the web during labeling.

[0060] A method for automatically bagging and labeling paper certificates includes an automatic paper certificate bagging and labeling device, and the steps are as follows:

[0061] (1) After the weighing system completes the weighing of the coil, it transmits the coil weight to the MES system to complete the collection of coil size data; the coil data collection judgment information is based on the last data of the coil. After the coil is weighed, all data is collected and qualified printing and bagging can be performed;

[0062] (2) The MES system sends the roll weight information to the industrial printer of the automatic paper certificate bagging and labeling device. The industrial printer prints the certificate. The certificate is printed on standard A4 paper. The information on the completion of certificate printing is determined by the number of copies defined by MES. After printing, a command is given and the data is sent from MES to the industrial level 1 network.

[0063] (3) The certificate falls into the plastic bag and is sealed. At the same time, the double-sided adhesive layer on the front side of the plastic bag is torn off by the adhesive layer peeling mechanism;

[0064] (4) The plastic bag containing the certificate falls into the labeling adsorption plate and waits for labeling;

[0065] (5) After the coil moves to the labeling position, the coil conveying device stops rotating;

[0066] (6) The labeling adsorption plate moves horizontally toward the coil, tears off the plastic bag, and locates the position of the certificate according to the specifications and position of the coil;

[0067] (7) The labeling adsorption plate pushes the plastic bag toward the roll material to achieve the attachment of the certificate.

[0068] In this embodiment, the data collection and determination information of the coil is realized by the completion of the weighing of the last data of the coil; for coils with a height of 1.5-2.1 meters, the position for affixing the certificate of conformity is unified at the position of 1.5 meters; for coils with a height of 0.8-1.5 meters, the position for affixing the certificate of conformity is unified at the position of 0.8 meters; for coils with a height of less than 0.8 meters, the position for affixing the certificate of conformity is unified at the position 0.1 meters below the highest point.

[0069] The above description is only a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, it does not require creative labor to design different forms of automatic paper certificate bagging and labeling devices and labeling methods. Without departing from the principles and spirit of the present invention, all equal changes, modifications, substitutions and variations made within the scope of the patent application of the present invention should fall within the scope of the present invention.
