Description

Technical Field

[0001] This application belongs to the technical field of luggage security inspection, and more specifically, relates to an automatic glue-changing device, a sealing and labeling machine, and an automatic glue-changing method. Background Art

[0002] A sealing and labeling machine is a device that uses tape to seal and label luggage, used for packaging and packing luggage, and at the same time attaching an electronic label to facilitate luggage security inspection.

[0003] In the prior art, a sealing and labeling machine is provided with a conveying device, a glue-cutting mechanism, a labeling mechanism, and a glue reel. A tape is wound around the glue reel. When the luggage passes through the conveying device, while the luggage is wound with the tape, the labeling mechanism also attaches a label to the luggage. The glue-cutting mechanism is used to cut the tape and clamp the head end of the tape to facilitate sealing the next piece of luggage. However, according to the different sizes of the luggage, the length of the tape used for each piece of luggage is also different. For large luggage, about 3 - 4 m of tape is required for one sealing, and for general luggage, 2 - 3 m of tape is also required. For a tape roll of general thickness, when the tape reaches a length of 500 m, the outer diameter of the tape is about 250 mm, and a tape with a length of 500 m can only seal about 15 pieces of luggage. Therefore, for flights with strict security controls, a single flight may require sealing more than 20 pieces, so it is necessary to alarm midway and replace the tape manually, which will cause the machine to stop midway, delay the luggage sealing time, and the use effect is not good. If the diameter of the tape is increased, it requires a larger size of the equipment, and it is not conducive to installation in many sites. Summary of the Invention

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0037] Please refer to Figures 1 to 3 together, and now an automatic glue - changing device 100 provided by the embodiment of the present application will be described. The automatic glue - changing device 100 includes: a winding ring 10, a plurality of glue - winding mechanisms 20, a rotational power mechanism 30, a glue - changing positioning mechanism 40, a glue - changing detection mechanism 50, and a push - rod mechanism 60.

[0038] Specifically, each of the tape winding mechanisms 20 includes a cylinder base 21, a glue disk 22, a winding drum 23, and a tape 24. The cylinder base 21 and the glue disk 22 are fixed to the winding ring 10. The winding drum 23 is clamped inside the cylinder base 21. The tape 24 is wound around the glue disk 22 and one end of the tape is fixed to the winding drum 23.

[0039] The rotation power mechanism 30 is used to drive the winding ring 10 to rotate. The glue replacement positioning mechanism 40 is used to detect the position of the tape winding mechanism 20. The glue replacement detection mechanism 50 is used to detect the remaining amount of the tape 24 on the glue disk 22. The push rod mechanism 60 can be inserted into the winding drum 23 to separate the winding drum 23 from the cylinder base 21 when the winding ring 10 rotates.

[0040] It can be understood that the automatic glue replacement device 100 can achieve automatic glue replacement by arranging a plurality of the tape winding mechanisms 20 on the winding ring 10.

[0041] As Figure 1 shown, three tape winding mechanisms 20 are arranged on the winding ring 10, and only one of them is the tape winding mechanism 20 in use, and the other two are spare tape winding mechanisms 20. For example, when the glue replacement detection mechanism 50 detects that the tape 24 in the currently used tape winding mechanism 20 is insufficient, the rotation power mechanism 30 can drive the winding ring 10 to rotate a certain angle. When the glue replacement positioning mechanism 40 detects that the spare tape winding mechanism 20 has rotated into place, the winding ring 10 stops rotating. The push rod mechanism 60 is inserted into the winding drum 23, and the winding ring 10 continues to rotate a certain angle. Since the tape 24 is wound around the glue disk 22 and one end of the tape is fixed to the winding drum 23, at this time, the winding drum 23 is separated from the cylinder base 21, and at the same time, the glue disk 22 will rotate while generating an action of pulling and peeling off the tape 24.

[0042] In the sealing and labeling machine, when the adhesive tape 24 is peeled off from the adhesive reel 22, the manipulator of the adhesive cutting mechanism of the sealing and labeling machine will first clamp the peeled portion of the adhesive tape 24, and the cutter of the adhesive cutting mechanism will cut off the head end of the adhesive tape 24, so that the reel 23 is freed from the restraint of the adhesive tape 24. At this time, the new head end of the adhesive tape 24 is clamped on the manipulator of the adhesive cutting mechanism, and when the luggage is transported to the middle of the winding ring 10 by the conveying device of the sealing and labeling machine, the rotating power mechanism 30 can drive the winding ring 10 to rotate one circle, so that the adhesive tape 24 is wound around the luggage. Subsequently, the manipulator of the glue cutting mechanism releases and retracts the tape 24, and the labeling mechanism of the sealing and labeling machine attaches the label to the tape 24 of the luggage. The rotating power mechanism 30 drives the winding ring 10 to rotate one circle again to fix the label. The manipulator of the glue cutting mechanism clamps the peeled tape 24 again, and the cutter of the glue cutting mechanism cuts the tape 24 again, thus completing the sealing of the luggage.

[0043] It is worth mentioning that the glue cutting mechanism and the labeling mechanism are mature existing technologies, and their structures are not described in detail in this specification.

[0044] Similarly, if the glue replacement detection mechanism 50 detects that the glue tape 24 in the currently used glue wrapping mechanism 20 is insufficient, the above steps can be repeated to rotate the next glue wrapping mechanism 20 to continue sealing the luggage until the glue tape 24 on all the glue wrapping mechanisms 20 of the winding ring 10 is used up, and then the glue disc 22 is replaced manually.

[0045] Compared with the prior art, the automatic glue changing device 100 provided in the present application can realize automatic remaining amount, precise positioning and glue changing of the adhesive tape 24 by simultaneously arranging multiple glue winding mechanisms 20 on the winding ring 10, and combining the adhesive tape changing detection mechanism 50, the adhesive tape changing positioning mechanism 40 and the push rod mechanism 60, thereby increasing the storage capacity of the adhesive tape 24 and improving the efficiency of luggage sealing.

[0046] In another embodiment of the present application, see Figure 3 The cartridge seat 21 is provided with an opening slot 211 , and the opening slot 211 is located on the side wall of the cartridge seat 21 .

[0047] It is understandable that, after the push rod mechanism 60 is inserted into the reel 23 , by providing an open groove 211 on the cartridge seat 21 , when the winding ring 10 rotates, it is convenient for the reel 23 to detach from the cartridge seat 21 through the open groove 211 .

[0048] In another embodiment of the present application, the roll 23 is a round paper roll.

[0049] It can be understood that the circular paper tube has a certain elasticity and can be clamped in the tube seat 21 by interference fit. When the push rod mechanism 60 is not inserted into the reel 23, it ensures that the circular paper tube will not fall off. After the push rod mechanism 60 is inserted into the reel 23, it is convenient for the reel 23 to disengage from the tube seat 21. In addition, the adhesive tape 24 has a high viscosity to the circular paper tube, which is convenient for the staff to peel off a section of the adhesive tape 24 in advance and paste it on the circular paper tube as a backup winding mechanism 20.

[0050] In another embodiment of the present application, please refer to Figure 1 and Figure 2 , the winding mechanism 20 further includes a plurality of guide wheels 25. The adhesive tape 24 is wound around the glue disc 22 and one end passes through a plurality of the guide wheels 25 in sequence and is fixed to the reel 23.

[0051] It can be understood that through a plurality of the guide wheels 25, the adhesive tape 24 can be guided to improve the stability of the adhesive tape 24.

[0052] In another embodiment of the present application, please refer to Figure 1 and Figure 2 , the rotation power mechanism 30 includes a motor 31, a conveyor belt 32 and a transmission wheel 33. The motor 31 is connected to the transmission wheel 33 through the conveyor belt 32, and the transmission wheel 33 drives the winding ring 10 to rotate.

[0053] It can be understood that the motor 31 is preferably a servo motor 31. The servo motor 31 has high control precision and is sensitive in response, which is beneficial to accurately control the position of the winding ring 10.

[0054] In another embodiment of the present application, please refer to Figure 1 and Figure 2 , the glue replacement positioning mechanism 40 includes a first infrared sensor 41. The first infrared sensor 41 is arranged on one side of the winding ring 10 and is used to sense whether the glue disc 22 rotates in place.

[0055] It can be understood that during the process of replacing the glue disc 22, the winding ring 10 needs to be rotated. When the spare glue disc 22 starts to block the infrared ray of the first infrared sensor 41, it means that the glue disc 22 rotates in place and the winding ring 10 stops rotating.

[0056] In another embodiment of the present application, please refer to Figure 1 and Figure 2, the glue replacement positioning mechanism 40 includes a second infrared sensor 42. A light guide hole 11 is provided on the winding ring 10. The second infrared sensor 42 is arranged on one side of the winding ring 10. The second infrared sensor 42 senses the winding ring 10 through the light guide hole 11 for positioning.

[0057] It can be understood that during the process of replacing the glue disk 22, the first infrared sensor 41 can sense whether the glue disk 22 rotates in place. When the first infrared sensor 41 rotates in place, the rotation speed of the winding ring 10 can be reduced. The second infrared sensor 42 precisely positions the winding ring 10. That is, when the infrared light emitted by the second infrared sensor 42 passes through the light guide hole 11, it indicates that the winding ring 10 has reached the full position. At this time, the winding ring 10 quickly stops, and the cutting mechanism of the sealing and labeling machine will start to work for cutting the glue.

[0058] In another embodiment of the present application, please refer to Figure 1 and Figure 2 , the glue replacement detection mechanism 50 includes a third infrared sensor 51. The third infrared sensor 51 is arranged on one side of the glue disk 22 and is used to detect the thickness of the tape 24 wound on the glue disk 22.

[0059] It can be understood that since each time the winding mechanism 20 seals the luggage, the glue disk 22 can be reset through the first infrared sensor 41 and the second infrared sensor 42, and the thickness of the tape 24 wound on the glue disk 22 will decrease. Therefore, when there is enough remaining amount of the tape 24 wound on the glue disk 22, the receiving end of the third infrared sensor 51 can receive the infrared rays emitted by the transmitting end. When the remaining amount of the tape 24 wound on the glue disk 22 is insufficient, the receiving end of the third infrared sensor 51 can receive the infrared rays emitted by the transmitting end, thereby realizing the automatic glue replacement function.

[0060] In another embodiment of the present application, please refer to Figure 1 and Figure 2 , the push rod mechanism 60 includes a glue replacement rod 61, a push rod cylinder assembly 62, a guiding slide rail 63, and a scraping cylinder plate 64. The glue replacement rod 61 is slidably arranged on the guiding slide rail 63. One end of the glue replacement rod 61 is fixed on the push rod cylinder assembly 62, and the other end passes through the scraping cylinder plate 64, so that when the push rod cylinder assembly 62 extends, the glue replacement rod 61 can be inserted into the reel 23 in the cylinder base 21, and when the push rod cylinder assembly 62 contracts, the scraping cylinder plate 64 can make the reel 23 fall off from the glue replacement rod 61.

[0061] It can be understood that during the process of replacing the glue reel 22, after the glue cutting mechanism cuts short the adhesive tape 24 connecting the glue reel 22 and the reel 23, by performing a contraction action on the push rod mechanism 60, the reel 23 can be detached from the glue changing rod 61 through the scraping cylinder plate 64, so that when replacing the glue reel 22 next time, the glue changing rod 61 can be inserted into the reel 23 of another winding mechanism 20 again.

[0062] Please refer to Figure 4 and Figure 5 , the present application also provides a sealing and labeling machine 200, which includes a conveying device 210, a glue cutting mechanism 220, a labeling mechanism 230, and the automatic glue changing device 100 as described above. The conveying device 210 is used to convey luggage, the automatic glue changing device 100 is used to wind the luggage and automatically replace the adhesive tape 24, the glue cutting mechanism 220 is used to clamp and cut the adhesive tape 24, and the labeling mechanism 230 is used to label the luggage.

[0063] Compared with the prior art, the sealing and labeling machine 200 provided by the present application simplifies the equipment structure and reduces the equipment volume by integrating the conveying device 210, the glue cutting mechanism 220, and the automatic glue changing device 100.

[0064] Please refer to Figure 6 , the present application also provides an automatic glue changing method 300, which includes the following steps:

[0065] Step S1, the glue changing detection mechanism 50 detects the remaining amount of the adhesive tape 24 on the glue reel 22 of the current winding mechanism 20. If it detects that the remaining amount of the adhesive tape 24 is insufficient, automatic glue changing starts;

[0066] Step S2, the rotation power mechanism 30 drives the winding ring 10 to rotate. When the glue changing positioning mechanism 40 detects that the winding mechanism 20 rotates in place, the winding ring 10 stops rotating;

[0067] Step S3, the push rod mechanism 60 extends and inserts into the reel 23;

[0068] Step S4, the rotation power mechanism 30 continues to drive the winding ring 10 to rotate a certain angle, so that the reel 23 is separated from the cylinder base 21, and the adhesive tape 24 is peeled off a certain distance from the glue reel 22;

[0069] Step S5, the manipulator of the glue cutting mechanism 220 clamps the peeled part of the adhesive tape 24, and the cutter of the glue cutting mechanism 220 cuts off the head end of the adhesive tape 24, so that the reel 23 is released from the bondage of the adhesive tape 24.

[0070] If the glue replacement detection mechanism 50 detects that the tape 24 in the current tape winding mechanism 20 in use is insufficient, the above steps can be cycled again to rotate the next tape winding mechanism 20 and continue to seal the luggage until the tape 24 on all the tape winding mechanisms 20 of the winding ring 10 is used up, and then the glue replacement tray 22 is replaced manually.

[0071] Compared with the prior art, the automatic glue replacement method 300 provided by this application effectively simplifies the manual glue replacement frequency and improves the efficiency of luggage sealing and labeling.

[0072] The above are only the preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
