Description

Technical Field

[0001] The present invention relates to the technical field of carton packaging equipment, and in particular to a device and a working method for applying adhesive tape inside a carton. Background Art

[0002] With the development of the carton packaging industry, automated packaging technology has emerged, which aims to improve packaging efficiency and reduce manual operations. Among them, the integrated nailing and gluing equipment is an important achievement. This type of equipment integrates the nailing and gluing functions to achieve rapid packaging of cartons, effectively improve production efficiency, and ensure that the tape can accurately cover the nails on the carton to prevent the exposed nails from scratching the product during transportation.

[0003] However, the above-mentioned integrated nailing and gluing equipment has limitations on carton types and production processes. In particular, for cartons of certain special specifications or that require manual nailing, such integrated equipment cannot be used directly because it cannot adapt to the operating requirements of automated equipment. In this case, workers need to manually attach tape to the carton to cover the exposed nails, which not only increases the complexity and time cost of manual operation, but may also cause uneven tape adhesion or inaccurate position due to human factors, thus affecting the protective effect and overall aesthetics of the packaging.

[0004] Therefore, there is an urgent need for a tape sticking device and a working method for the inside of a carton to improve production efficiency and reduce labor costs. Summary of the invention

[0005] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a device with a rational structure, which can perform tape application on the inside of the carton, detect whether the tape application is qualified, and discharge defective products, thereby improving production efficiency and reducing labor costs.

[0006] The technical solution adopted by the present invention is as follows: A device for applying adhesive tape inside a carton, comprising:

[0007] The tape sticking mechanism is used to put the carton into the carton and use the tape sticking machine to stick tape inside. After the sticking operation is completed, the color sensor is used to detect whether the tape inside the carton is stuck well;

[0008] The discharge mechanism is used to receive the cartons taped by the taping mechanism and discharge them to different workstations according to the taping status of the cartons;

[0009] The adhesive tape applying mechanism comprises a first frame, a first station and a second station are respectively arranged on the top of the first frame, and the first station and the second station are centrally symmetrically distributed;

[0010] The first station is used for feeding cartons, and the feeding end of the first station is facing the operator. The second station is used for discharging cartons 400, and the discharging end of the second station is facing the feeding port of the discharging mechanism.

[0011] The first station and the second station are both provided with a tape applying machine for applying tape to the inside of the carton and a color sensor for detecting whether the tape applying operation is good;

[0012] It also includes a rotating mechanism, the output end of which is connected to the bottom surface of the tape sticking mechanism via the supporting mechanism, and the rotating mechanism is used to rotate to exchange the position between the first station and the second station. After the carton is loaded at the first station and the internal tape sticking operation is completed by the tape sticking machine, it is rotated to the position of the second station via the rotating mechanism and the carton with the tape stuck inside is sent to the discharge mechanism.

[0013] In one of the embodiments, the taping mechanism also includes a tape arranged on a mounting seat, and a tape machine cooperates with the tape to perform a taping operation on the inside of the carton; a color sensor is arranged at the rear of the tape machine, and the carton passes through the color sensor when being discharged to detect whether the taping operation is good.

[0014] In one of the embodiments, baffles are provided on both sides of the first station and the second station to limit the movement trajectory of the cartons being pushed in and out.

[0015] In one embodiment, the rotating mechanism includes a rotating driving member, the output end of the rotating driving member drives the driving gear to rotate, one side of the driving gear is meshed with the driven gear, the top of the driven gear is connected to the rotating table, a supporting mechanism is fixed on the top of the rotating table, and a tape mechanism is fixed on the upper part of the supporting mechanism.

[0016] In one of the embodiments, the discharge mechanism includes a second frame, a discharge station is arranged on the second frame, a lower baffle is arranged on one side of the discharge station, and an upper baffle is also assembled on the other side of the discharge station through a bracket, and the lower baffle and the upper baffle cooperate to limit the movement trajectory of the carton at the discharge station.

[0017] In one of the embodiments, a push-out assembly is provided at the bottom of the lower baffle, and the output end of the push-out assembly is facing the direction of the upper baffle; both sides of the upper baffle are connected to a flip assembly, and the flip assembly is used to drive the upper baffle to flip upward.

[0018] In one of the embodiments, the carton includes at least two states: good tape application and poor tape application. When the color sensor detects that the carton has poor tape application, the flip assembly drives the upper baffle to flip upward, and at the same time the push-out assembly starts to push the carton from the discharge station to the NG position. When the color sensor detects that the carton has good tape application, the push-out assembly and the flip assembly are not started, and the carton is sent to the next process via the discharge station.

[0019] In one embodiment, the ejection assembly includes an ejection cylinder, and a ejection head is fixed to the output end of the ejection cylinder.

[0020] In one of the embodiments, the flip assembly includes two rotation drive devices respectively arranged on both sides of the upper baffle and connected to the upper baffle.

[0021] A working method using the above-mentioned tape sticking device for the inside of a carton includes the following steps:

[0022] Put the carton into the first station of the tape sticking mechanism, and use the tape sticking machine on the first station to stick tape on the inside of the carton;

[0023] After the tape application is completed, the rotary mechanism rotates to exchange the positions of the first station and the second station. At this time, the discharging side of the first station is facing the discharge mechanism, and the second station is used for the operator to load another carton that is not taped.

[0024] The first station sends the cartons with tape to the discharge mechanism. During the transportation process, the color sensor detects whether the tape inside the carton is well affixed.

[0025] According to the test results, the cartons include at least two states: good tape application and bad tape application;

[0026] When the carton is detected by the color sensor to be well taped, the carton is discharged to the next process through the discharge mechanism;

[0027] When the carton is detected as having poor tape application by the color sensor, the carton is discharged to the NG position through the discharge mechanism;

[0028] The rotating mechanism rotates again to exchange the positions of the first station and the second station, and repeats the above steps to perform the tape application, inspection, and transport and discharge operations.

[0029] The beneficial effects of the present invention are as follows:

[0030] The invention has a compact structure and is easy to operate. Through the coordinated work of the adhesive tape sticking mechanism, the rotating mechanism and the discharging mechanism, the fully automated operation of sticking adhesive tape inside the carton is realized, and the production efficiency is significantly improved. At the same time, through the cooperation of the first station and the second station, the invention does not need to suspend the loading of materials. The operator only needs to exchange the positions of the first station and the second station through the rotating mechanism to continue loading the carton at the exchanged station, and the station exchanged to the discharging mechanism sends the carton into the discharging mechanism after being inspected by the color sensor and waits for the next exchange of stations.

[0031] The present invention also has the following advantages:

The automated operation process reduces the dependence on manual labor and reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] like Figure 1-Figure 2 As shown, in this embodiment, a tape applying device for the inside of a carton includes a tape applying mechanism 100 , a rotating mechanism 200 and a discharging mechanism 300 .

[0053] Combination Figure 3-Figure 4 As shown, in this embodiment, the tape applying mechanism 100 is used to apply tape to the inside of the carton 400, and the structure of the tape applying mechanism 100 is as follows:

[0054] The first frame 110 is used as the main support structure of the adhesive tape applying mechanism 100. A first station 120 and a second station 130 are respectively arranged on the top of the first frame 110. The first station 120 and the second station 130 are centrally symmetrically distributed.

[0055] The first station 120 is used for feeding cartons 400, and its feeding end faces the operator, so that the operator can put the cartons 400 in conveniently;

[0056] The second station 130 is used for discharging the cartons 400, and its discharging end is aligned with the feeding port of the discharging mechanism 300 to ensure that the cartons 400 with adhesive tape can smoothly enter the discharging mechanism 300;

[0057] A mounting seat 140 is provided on each of the first station 120 and the second station 130 for mounting an adhesive tape 150 and an adhesive tape applying machine 160;

[0058] Furthermore, the tape machine 160 cooperates with the tape 150 to apply tape to the inside of the carton 400. The tape machine 160 can accurately control the sticking position and strength of the tape to ensure that the tape is firmly attached.

[0059] Furthermore, a color sensor 170 is provided behind the tape applicator 160 to detect the adhesion of the tape inside the carton 400. When the carton 400 is discharged, it passes through the color sensor 170, and the sensor can determine whether the tape is well attached and transmit the detection result to the control system.

[0060] In this embodiment, baffles 180 are provided on both sides of the first station 120 and the second station 130 to limit the movement trajectory of the carton 400 when being pushed in and out, thereby ensuring the stability of the carton 400 during operation.

[0061] Combination Figure 5 As shown, in this embodiment, a support mechanism 500 is fixed on the top of the rotating mechanism 200 , and a tape applying mechanism 100 is fixed on the upper part of the support mechanism 500 .

[0062] At the same time, combine Figure 6 As shown, in this embodiment, the rotating mechanism 200 is used to realize the position exchange between the first station 120 and the second station 130 in the tape applying mechanism 100, so as to continuously perform the loading, tape applying, detection and conveying and discharging operations; further, the specific structure of the rotating mechanism 200 is as follows:

[0063] The rotating driving member 210 serves as a power source of the rotating mechanism 200 , and the output end of the rotating driving member 210 drives the driving gear 220 to rotate; one side of the driving gear 220 is meshed with the driven gear 230 , and the rotational motion is realized through gear transmission; the top of the driven gear 230 is connected to the rotating table 240 , and the rotating table 240 rotates under the drive of the driving gear 220 .

[0064] Specifically, the support mechanism 500 is fixed on the top of the rotating table 240, and the tape applying mechanism 100 is fixed on the upper part of the support mechanism 500. When the rotating table 240 rotates, the tape applying mechanism 100 is driven to rotate together, so that the position exchange between the first station 120 and the second station 130 is realized.

[0065] Combination Figure 7-Figure 8As shown, in this embodiment, the discharge mechanism 300 is used to receive the cartons 400 taped and discharged by the taping mechanism 100, and discharge them to different stations (such as a qualified station or an NG station) according to the taping status of the cartons 400.

[0066] Furthermore, the specific structure of the discharge mechanism 300 is as follows:

[0067] The second frame 310 serves as the main supporting structure of the discharge mechanism 300 , and a discharge station 320 is disposed on the second frame 310 ;

[0068] The discharge station 320 is used to receive the carton 400 discharged from the tape applying mechanism 100;

[0069] A lower baffle 330 is provided on one side of the discharge station 320, and an upper baffle 350 is installed on the other side through a bracket 340. The lower baffle 330 and the upper baffle 350 cooperate to limit the movement trajectory of the carton 400 at the discharge station 320;

[0070] A push-out assembly 360 is disposed at the bottom of the lower baffle 330 , and an output end of the push-out assembly 360 is facing the direction of the upper baffle 350 ;

[0071] Both sides of the upper baffle 350 are connected to the flip assembly 370, and the flip assembly 370 is used to drive the upper baffle 350 to flip upward;

[0072] When the color sensor 170 detects that the carton 400 has poor tape application, the flip assembly 370 drives the upper baffle 350 to flip upward to provide space for the push assembly 360 to push the carton 400. The push assembly 360 then pushes the carton 400 into the NG position in the direction of the upper baffle 350.

[0073] Furthermore, the pushing component 360 specifically includes a pushing cylinder, and a pushing head is fixed at the output end of the pushing cylinder.

[0074] Furthermore, the flip assembly 370 specifically includes two rotation driving devices respectively arranged on both sides of the upper baffle 350 and connected to the upper baffle 350 .

[0075] In actual work, the working method of the present invention includes the following process:

[0076] The carton 400 is placed in the first station 120 of the tape applying mechanism 100, and the tape applying machine 160 on the first station 120 applies tape to the inside of the carton 400;

[0077] After the tape application is completed, the rotating mechanism 200 rotates to exchange the positions of the first station 120 and the second station 130. At this time, the discharging side of the first station 120 is facing the discharge mechanism 300, and the second station 130 is used for the operator to load another untaped carton 400;

[0078] The first station 120 delivers the carton 400 with the adhesive tape affixed to the discharge mechanism 300. During the transportation process, the color sensor 170 detects whether the adhesive tape inside the carton 400 is affixed properly.

[0079] According to the test results, the carton 400 includes at least two states: good tape application and bad tape application.

[0080] When the carton 400 is detected by the color sensor 170 to be well taped, the ejection assembly 360 and the flip assembly 370 are not started, and the carton 400 is sent to the next process through the discharge station 320;

[0081] When the color sensor 170 detects that the carton 400 has a bad tape application, the flip assembly 370 drives the upper baffle 350 to flip upward, and the push-out assembly 360 starts to push the carton 400 from the discharge station 320 to the NG position;

[0082] The rotating mechanism 200 rotates again to exchange the positions of the first station 120 and the second station 130, and repeats the above steps to perform the tape application, inspection, and transport and discharge operations.

[0083] The structure of the present invention is reasonable. Through the coordinated work of the taping mechanism 100, the rotating mechanism 200 and the discharging mechanism 300, the automated operation of taping the inside of the carton 400 is realized, which significantly improves the production efficiency. At the same time, through the cooperation of the color sensor 170 and the discharging mechanism 300, the quality of the taping operation is ensured and the production of defective products is avoided.

[0084] In this embodiment, the principle of using the color sensor 170 to detect whether the adhesive tape is well applied is as follows: using the color sensor 170 to detect whether there are nails not covered by the adhesive tape 150 . If uncovered nails are detected, the adhesive tape is poorly applied.

[0085] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above-mentioned embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
