Description

Technical Field

[0001] The present invention belongs to the technical field of tobacco packaging equipment, and particularly relates to a misaligned trademark paper detection device and method for a small box of a high-speed packaging machine. Background Art

[0002] The FOCKE752 transparent paper packaging machine is the main model of the ultra-high-speed packaging equipment in the existing tobacco packaging. Its function is to wrap a layer of transparent paper outside the small box cigarette pack, and the transparent paper is heat-sealed by a soldering iron for the moisture preservation, storage and transportation of the product. However, during the production process, there may be a situation where the brand number of the small box trademark paper is inconsistent with the online production brand number during the transportation of the small box trademark paper from the stock preparation area to the small box packaging machine or during the cigarette pack transportation process before the small box cigarette pack enters the FX752 transparent paper packaging machine. Once the small box trademark paper is misaligned and the operator fails to detect it in time, it will cause unqualified products to flow into the market, resulting in serious quality accidents and damaging the interests of consumers. And there is no detection device on the FOCKE752 transparent paper packaging machine to effectively detect the misalignment of the small box trademark paper. Summary of the Invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a misaligned trademark paper detection device for a small box of a high-speed packaging machine. The device has a simple structure and strong versatility, can effectively detect the brand number of the small box trademark paper, can avoid the occurrence of quality accidents, and is beneficial to protecting the interests of consumers; the method can effectively detect the situation where the brand number of the small box trademark paper is inconsistent with the online production brand number, has a low detection cost, and can effectively ensure the ex-factory quality of the product.

[0004] To achieve the above object, the present invention provides a misaligned trademark paper detection device for a small box of a high-speed packaging machine, including a support three located above the cigarette pack guide rail and fixedly connected to the FOCKE752 transparent paper packaging machine, a detection unit one and a detection unit two;

[0005] The detection unit one includes a support one, a support two, a photoelectric switch one and a color sensor one; the detection unit two includes a support four, a support five, a photoelectric switch two and a color sensor two;

[0006] The support two, the support one, the support four and the support five are sequentially and spacedly installed at the lower part of the support three in the front-rear direction;

[0007] The photoelectric switch one and the photoelectric switch two are respectively fixedly connected to the lower parts of the support two and the support four, and respectively face the cigarette pack guide rail one and the cigarette pack guide rail two;

[0008] The color sensor one and the color sensor two are respectively fixedly connected to the lower parts of the support one and the support five, and respectively face the cigarette pack guide rail one and the cigarette pack guide rail two;

[0009] The photoelectric switch 1, color sensor 1, photoelectric switch 2 and color sensor 2 are each connected to the PLC controller of the FOCKE 752 transparent paper packaging machine.

[0010] In this technical solution, the photoelectric switch can detect the cigarette pack and send a signal to the PLC controller when the cigarette pack leaves its detection range. Then, the PLC controller can use the photoelectric switch to locate whether the cigarette pack reaches the detection position of the color sensor, and start the color sensor for color detection when determining the position of the cigarette pack. Furthermore, the color sensor can effectively detect whether the color of the small box label paper is within the reference range, and count through the counter when the color does not conform, so as to facilitate subsequent rejection or stop control and alarm operations. In this way, through the setting of the detection unit, the adverse effects caused by mislabeled cigarette packs flowing into the market can be effectively avoided, and serious accidents can be effectively prevented. The structure of the present invention is simple, has a relatively high recognition rate, low manufacturing cost, is easy to implement, easy to maintain, can be directly installed and used on the original machine, has a large scope of application, and is easy to promote.

[0011] Furthermore, in order to facilitate the adjustment of the positions of the photoelectric switch 1 and 2 in the left-right direction, a strip-shaped sliding groove 1 extending in the left-right direction is provided in the corresponding part of the bracket 2 for the photoelectric switch 1, and the photoelectric switch 1 is connected to the strip-shaped sliding groove 1 through a bolt; a strip-shaped sliding groove 2 extending in the left-right direction is provided in the corresponding part of the bracket 4 for the photoelectric switch 2, and the photoelectric switch 2 is connected to the strip-shaped sliding groove 2 through a bolt.

[0012] Furthermore, in order to facilitate the access and disconnection of the detection unit, a detection start-stop control module connected to the PLC controller is also included, and the detection start-stop control module is used for the operator to control the start and stop of the detection units 1 and 2.

[0013] Furthermore, in order to promptly reject the cigarette pack when the color of the label paper is incorrect, a cigarette pack rejection module connected to the PLC controller and installed on the FOCKE 752 transparent paper packaging machine is also included.

[0014] Furthermore, in order to facilitate alarm reminder, an alarm connected to the PLC controller is also included.

[0015] As a preference, both the color sensor 1 and the color sensor 2 are fiber optic color sensors.

[0016] Furthermore, in order to improve the detection accuracy, both the color sensor 1 and the color sensor 2 are inclinedly arranged, and the inclination angle is 15°.

[0017] Further, to improve the detection accuracy, the heights of the sensing surfaces of the color sensor 1 and the photoelectric switch 1 from the cigarette packs on the cigarette pack guide rail 1 are 5 cm and 3 cm respectively; the heights of the sensing surfaces of the color sensor 2 and the photoelectric switch 2 from the cigarette packs on the cigarette pack guide rail 2 are 5 cm and 3 cm respectively.

[0018] The present invention also provides a method for detecting misaligned small box trademark papers of a high-speed packaging machine, including the following steps:

[0019] Step 1: Install the support 2 and the support 1 above the cigarette pack guide rail 1 respectively through the support 3 connected to the FOCKE752 transparent paper packaging machine, install the support 4 and the support 5 above the cigarette pack guide rail 2 respectively, install the photoelectric switch 1 and the color sensor 1 facing the cigarette pack guide rail 1 at the lower parts of the support 2 and the support 1 respectively, and install the photoelectric switch 2 and the color sensor 2 facing the cigarette pack guide rail 2 at the lower parts of the support 4 and the support 5 respectively;

[0020] Step 2: Start the detection unit 1 and the detection unit 2 through the detection start-stop control module;

[0021] Step 3: When the photoelectric switch 1 and the photoelectric switch 2 detect that there is a cigarette pack and no cigarette pack below respectively, they output high level and low level. After being triggered to work, the color sensor 1 and the color sensor 2 detect the color on the trademark paper, and compare the color on the trademark paper with the taught reference color. When the color on the trademark paper coincides with the reference color within a certain error range, it outputs high level, otherwise it outputs low level;

[0022] When the photoelectric switch 1 detects that the cigarette pack leaves its lower detection range, it outputs low level to the PLC controller. When the PLC controller receives the low level sent by the photoelectric switch 1, it controls the color sensor 1 to work. The color sensor 1 detects the color on the trademark paper. When the detected color is within the reference color range, it outputs high level to the PLC controller. When the detected color is not within the reference color range, it outputs low level to the PLC controller. Each time the PLC controller receives the low level sent by the color sensor 1, it controls the counter 1 inside it to add 1 for marking. At the same time, it controls the cigarette pack rejection module connected to it to reject the cigarette packs with wrong colors. When the count of the counter 1 is 3, the counter 1 is reset, and it controls the FOCKE752 transparent paper packaging machine to stop the operation of the cigarette pack guide rail 1 and controls the alarm to alarm;

[0023] When the photoelectric switch two detects that the cigarette pack leaves its lower detection range, it outputs a low level to the PLC controller. When the PLC controller receives the low level sent by the photoelectric switch two, it controls the color sensor two to work. The color sensor two detects the color on the label paper. When it detects that the color is within the reference color range, it outputs a high level to the PLC controller. When it detects that the color is not within the reference color range, it outputs a low level to the PLC controller. After the PLC controller receives the low level sent by the color sensor two each time, it controls the internal counter two to increment by 1 for marking. At the same time, it controls the connected cigarette pack rejection module to reject the cigarette packs with incorrect colors. When the count of the counter two reaches 3, the counter two is reset, and it controls the FOCKE752 transparent paper packaging machine to stop the operation of the cigarette pack guide two and controls the alarm to sound;

[0024] Step 4: After the counts of both the counter one and the counter two inside the PLC controller reach 3 and are reset, the PLC controller controls the FOCKE752 transparent paper packaging machine to stop working as a whole.

[0025] Further, in step one, the distances from the sensing surfaces of the color sensor one and the photoelectric switch one to the cigarette pack on the cigarette pack guide one are 5 cm and 3 cm respectively; the distances from the sensing surfaces of the color sensor two and the photoelectric switch two to the cigarette pack on the cigarette pack guide two are 5 cm and 3 cm respectively.

[0026] This method realizes the effective detection of the color of the label paper by using simple electrical components, thereby effectively avoiding the adverse effects caused by the wrong-brand label paper cigarette packs flowing into the market. Furthermore, it can effectively avoid the situation of wrong-brand label paper flowing into the market and prevent serious accidents from occurring. Description of the Drawings

[0031] The present invention will be further described below with reference to the drawings.

[0032] As Figure 1 and Figure 2As shown in the figure, a misaligned trademark paper detection device for small boxes of a high-speed packaging machine includes a support three 6, a detection unit one, and a detection unit two, which are located above the cigarette packet guide rail and fixedly connected to the FOCKE752 transparent paper packaging machine;

[0034] The support two 3, the support one 2, the support four 8, and the support five 9 are sequentially and spaced apart in the front-rear direction and installed at the lower part of the support three 6; the support three 6 extends in the front-rear direction, wherein the support two 3 and the support five 9 are respectively fixedly connected to both ends of the support three 6 through connecting bolts, and the support one 2 and the support four 8 are respectively fixedly connected to the lower parts of the support two 3 and the support five 9 through connecting bolts, thus facilitating the adjustment of the positions of each support;

[0036] The color sensor one 5 and the color sensor two 10 are respectively fixedly connected to the lower parts of the support one 2 and the support five 9 and respectively face the cigarette packet guide rail one 11 and the cigarette packet guide rail two 12;

[0037] The photoelectric switch one 1, the color sensor one 5, the photoelectric switch two 7, and the color sensor two 10 are each connected to the PLC controller of the FOCKE752 transparent paper packaging machine.

[0038] The photoelectric switch can detect the cigarette packet and send a signal to the PLC controller when the cigarette packet leaves its detection range. Furthermore, the PLC controller can use the photoelectric switch to locate whether the cigarette packet reaches the detection position of the color sensor, and start the color sensor for color detection when determining the position of the cigarette packet. Furthermore, the color sensor can effectively detect whether the color of the small box trademark paper is within the reference range, and count through the counter when the color does not conform, so as to facilitate subsequent rejection or shutdown control and alarm operations. In this way, through the setting of the detection unit, the adverse effects caused by misaligned trademark paper cigarette packets flowing into the market can be effectively avoided, and serious accidents can be effectively prevented. The structure of the present invention is simple, has a relatively high recognition rate, low manufacturing cost, is easy to implement, easy to maintain, can be directly installed and used on the original machine, has a large scope of application, and is easy to promote.

[0041] To timely remove the cigarette packs when the color of the label paper is incorrect, a cigarette pack removal module connected to the PLC controller and installed on the FOCKE752 transparent paper packaging machine is further included.

[0042] To facilitate alarm reminder, an alarm connected to the PLC controller is further included.

[0044] As a preference, the models of the color sensor 1 5 and the color sensor 2 10 are MICRO - EPSILON LT1 - ST; the models of the photoelectric switch 1 and the photoelectric switch 2 10 are PEPPERL&FUCHS ML4.2 - 8 - H - 20 - RT;

[0045] To improve the detection accuracy, the heights from the sensing surfaces of the color sensor 1 5 and the photoelectric switch 1 to the cigarette pack 4 on the cigarette pack guide rail 1 11 are 5 cm and 3 cm respectively; the heights from the sensing surfaces of the color sensor 2 10 and the photoelectric switch 2 7 to the cigarette pack 4 on the cigarette pack guide rail 2 12 are 5 cm and 3 cm respectively. As a preference, the horizontal distance in the front - back direction between the photoelectric switch 1 and the color sensor 1 is 2 / 3 of the length of the cigarette pack 4; the horizontal distance in the front - back direction between the photoelectric switch 2 and the color sensor 2 is 2 / 3 of the length of the cigarette pack 4.

[0046] As Figure 3 shown, the present invention also provides a method for detecting mislabeled small - box label paper of a high - speed packaging machine, including the following steps:

[0047] Step 1: Install support two 3 and support one 2 above the cigarette pack guide rail one 11 respectively through support three 6 connected to the FOCKE752 transparent paper packaging machine, install support four 8 and support five 9 above the cigarette pack guide rail two 12 respectively, install photoelectric switch one 1 and color sensor one 5 facing the cigarette pack guide rail one 11 at the lower parts of support two 3 and support one 2 respectively, and install photoelectric switch two 7 and color sensor two 10 facing the cigarette pack guide rail two 12 at the lower parts of support four 8 and support five 9 respectively;

[0048] Step 2: Start detection unit one and detection unit two through the detection start-stop control module; the access and disconnection of detection unit one and two to work can be conveniently controlled through the settings of the detection start-stop control module.

[0049] Step 3: When photoelectric switch one 1 and photoelectric switch two 7 detect the presence and absence of a cigarette pack below respectively, they output high level and low level. After being triggered to work, color sensor one 5 and color sensor two 10 detect the color on the label paper, and compare the color on the label paper with the taught reference color. When the color on the label paper coincides with the reference color within a certain error range, it outputs high level, otherwise it outputs low level; the correct color of the label paper is collected in advance by color sensor one 5 and color sensor two 10 to facilitate the subsequent color detection process;

[0050] When photoelectric switch one 1 detects that the cigarette pack leaves its lower detection range, it outputs low level to the PLC controller. When the PLC controller receives the low level sent by photoelectric switch one 1, it controls color sensor one 5 to work. Color sensor one 5 detects the color on the label paper. When the detected color is within the reference color range, it outputs high level to the PLC controller. When the detected color is not within the reference color range, it outputs low level to the PLC controller. Each time the PLC controller receives the low level sent by color sensor one 5, it controls the counter one inside it to increment by 1 for marking. At the same time, it controls the cigarette pack rejection module connected to it to reject the cigarette packs with wrong colors. When the count of counter one reaches 3, counter one is reset, and it controls the FOCKE752 transparent paper packaging machine to stop the operation of cigarette pack guide rail one 11 and controls the alarm to sound; as a preference, the alarm is a sound and light alarm module.

[0051] When the photoelectric switch II 7 detects that the cigarette pack has left its lower detection range, it outputs a low level to the PLC controller. When the PLC controller receives the low level sent by the photoelectric switch II 7, it controls the color sensor II 10 to work. The color sensor II 10 detects the color on the label paper. When it detects that the color is within the reference color range, it outputs a high level to the PLC controller. When it detects that the color is not within the reference color range, it outputs a low level to the PLC controller. After the PLC controller receives the low level sent by the color sensor II 10 each time, it controls the internal counter II to increment by 1 for marking. At the same time, it controls the cigarette pack rejection module connected to it to reject the cigarette packs with wrong colors. When the count of the counter II reaches 3, the counter II is reset, and the PLC controller controls the FOCKE 752 transparent paper packaging machine to stop the operation of the cigarette pack guide rail II 12 and controls the alarm to sound;

[0052] Step 4: After the counts of both the counter I and the counter II inside the PLC controller reach 3 and are reset, the PLC controller controls the FOCKE 752 transparent paper packaging machine to stop working as a whole.

[0053] In step one, the distances from the sensing surfaces of the color sensor I and the photoelectric switch I to the cigarette packs on the cigarette pack guide rail I are 5 cm and 3 cm respectively; the distances from the sensing surfaces of the color sensor II and the photoelectric switch II to the cigarette packs on the cigarette pack guide rail II are 5 cm and 3 cm respectively.

[0054] This method uses simple electrical components to effectively detect the color of the label paper, thus effectively avoiding the adverse effects caused by misbranded label paper cigarette packs flowing into the market. Furthermore, it can effectively avoid the situation of misbranded label paper flowing into the market and prevent serious accidents from occurring.
