[0055] In the description of the present disclosure, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present disclosure.

[0056] In addition, the technical features involved in the different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0057] Packaging machines, such as the GD-X2 packaging machine, generally include a cigarette feeding system, an aluminum foil paper feeding system, an inner frame paper feeding and forming system, and a trademark paper feeding and forming system. A qualified cigarette package is produced by arranging the cigarettes into groups and wrapping them in sequence with aluminum foil paper, inner frame paper, and trademark paper.

[0058] Among them, the aluminum foil supply system is used to supply aluminum foil, and in the process of supplying aluminum foil, the aluminum foil is embossed and cut to form a single sheet of aluminum foil with embossing, which is provided to subsequent links.

[0059] Figure 1-Figure 3 The aluminum foil paper supply system and control method thereof of the present disclosure are exemplarily shown.

[0060] See also Figure 1The aluminum foil supply system 10 includes an aluminum foil supply device 1, and the aluminum foil supply device 1 includes two aluminum foil supply assemblies 11. The two aluminum foil supply assemblies 11 are arranged side by side, for example, arranged in the left-right direction. The two aluminum foil supply assemblies 11 have the same structure, and both include a paper tray 12, an embossing mechanism 1b and a cutting mechanism 1a. The embossing mechanism 1b includes an embossing roller 14. The cutting mechanism 1a includes a paper cutter 16. For the convenience of distinction, the two aluminum foil supply assemblies 11 can be named "left" and "right" or "first" and "second" respectively, and the components in the two aluminum foil supply assemblies 11, such as the paper tray 12, the embossing mechanism 1b, the cutting mechanism 1a, the embossing roller 14 and the paper cutter 16, can also be named "left" and "right" or "first" and "second".

[0061] In the same aluminum foil supply assembly 11, the paper tray 12, the embossing roller 14 and the paper cutter 16 are arranged in sequence along the conveying direction of the aluminum foil 3. The paper tray 12 reels the aluminum foil 3. The embossing roller 14 embosses the aluminum foil 3 extending from the paper tray 12. The paper cutter 16 cuts the aluminum foil 3. A plurality of guide rollers 13 are arranged between the paper tray 12 and the embossing roller 14 and between the embossing roller 14 and the paper cutter 16 for guiding.

[0062] During operation, the aluminum foil 3 wound on the paper tray 12 passes through the guide roller 13 according to a preset route and reaches the embossing roller 14 and the paper cutter 16 in sequence.

[0063] At the embossing roller 14, the embossing roller 14 rolls the aluminum foil 3 and embosses a pattern at a predetermined position of the aluminum foil 3, so that the aluminum foil 3 has embossing, so as to improve the product packaging quality, increase the product anti-counterfeiting identification ability, and enhance the corporate image and reputation. Figure 2 In some embodiments, the embossing mechanism 1b includes not only the embossing roller 14 but also an embossing control mechanism 18. The embossing control mechanism 18 is connected to the embossing roller 14 to drive the embossing roller 14 to disengage or engage. When the embossing roller 14 is engaged, the aluminum foil 3 is crushed to achieve the embossing purpose. Specifically, in some embodiments, the embossing control mechanism 18 includes an embossing solenoid valve 182 and an embossing cylinder 181. The embossing cylinder 181 is connected to the embossing roller 14. The embossing solenoid valve 182 is arranged on the air path of the embossing cylinder 181, and controls the on-off of the air path of the embossing cylinder 181 to control the extension and retraction of the embossing cylinder 181, and further controls the disengagement or engagement of the embossing roller 14. The disengagement and engagement of the embossing roller 14 refers to, Figure 1 The disengagement and engagement between the patterned rollers shown in dashed lines and the non-patterned rollers shown in solid lines.

[0064] At the paper cutter 16, the paper cutter 16 is activated to cut the aluminum foil 3 into single sheets that meet the requirements for use in subsequent links. Figure 2In some embodiments, the cutting mechanism 1a includes not only the paper cutter 16 but also a cutting control mechanism 17. The cutting control mechanism 17 is connected to the paper cutter 16 to drive the paper cutter 16 to perform cutting. Specifically, in some embodiments, the cutting control mechanism 17 includes a cutting solenoid valve 172 and a cutting cylinder 171. The cutting cylinder 171 is connected to the paper cutter 16. The cutting solenoid valve 172 is disposed on the air path of the cutting cylinder 171 and controls the opening and closing of the air path of the cutting cylinder 171 to control the extension and contraction of the cutting cylinder 171, thereby controlling whether the paper cutter 16 performs the cutting action.

[0065] In actual use, the two aluminum foil supply components 11 supply aluminum foil 3 separately, and the two work in a switching manner, that is, when one aluminum foil supply component 11 supplies aluminum foil 3, the other aluminum foil 3 does not supply aluminum foil 3. When needed, the working aluminum foil supply component 11 is switched to the other aluminum foil supply component 11, and the other aluminum foil supply component 11 transports the aluminum foil 3 to the subsequent link.

[0066] In order to facilitate the switching of the two aluminum foil supply components 11, see Figure 1-3 In the embodiment of the present disclosure, the aluminum foil paper supply system 10 further includes a switching control device 2. The switching control device 2 includes an encoder 21 and two detection devices 22. The encoder 21 detects whether the action phase of the paper cutter 16 and the embossing roller 14 is reached. The two detection devices 22 correspond one to one with the two aluminum foil paper supply components 11. The detection device 22 detects whether the aluminum foil 3 in the aluminum foil paper supply component 11 is exhausted, broken or has a joint, and detects whether the embossing roller 14 is in the initial position. The switching control device 2 controls the two aluminum foil paper supply components 11 to switch to work according to the detection results of the encoder 21 and the two detection devices 22.

[0067] Based on the switching control device 2, the aluminum foil supply system 10 can control the two aluminum foil supply components 11 to switch and realize the automatic switching of the two aluminum foil supply components 11. Therefore, compared with the manual switching method in the related art, it can effectively improve the switching efficiency and reduce the labor intensity of the operator.

[0068] Among them, the detection device 22 detects whether the aluminum foil 3 in the aluminum foil supply component 11 has been used up, broken or has a joint, and can determine whether the aluminum foil supply component 11 has abnormal conditions such as running out of paper, breaking of paper, and having a joint on the paper. The corresponding detection results can be used as a basis for judging whether switching is required and whether switching can be performed. For example, for the aluminum foil supply component 11 that is working, if the corresponding detection device 22 detects that it has any of the conditions of running out of paper, breaking of paper, and having a joint on the paper, it indicates that the aluminum foil supply component 11 has an abnormal condition and needs to be switched to another aluminum foil supply component 11. For another example, for the aluminum foil supply component 11 that is not working, if the corresponding detection device 22 detects that it has any of the conditions of running out of paper, breaking of paper, and having a joint on the paper, it indicates that the aluminum foil 3 in the aluminum foil supply component 11 also has an abnormal condition, and the aluminum foil supply component 11 is not ready yet and cannot be switched.

[0069] The detection device 22 detects whether the embossing roller 14 is in the initial position, which is mainly used to combine with the detection result of the detection device 22 on the aluminum foil 3 to determine whether the non-operating aluminum foil supply component 11 is ready. The initial position of the embossing roller 14 refers to the position of the embossing roller 14 when the position of the pattern on the embossing roller 14 corresponds to the position of the pattern to be embossed on the aluminum foil 3. If it is detected that the embossing roller 14 is in the initial position, it indicates that the aluminum foil 3 has been inserted into the roller in place. Therefore, by detecting whether the embossing roller 14 is in the initial position, it can be determined whether the aluminum foil 3 has been inserted into the roller in place. In this way, when the detection device 22 detects that the embossing roller 14 in the non-working aluminum foil paper supply component 11 is in the initial position, and the aluminum foil 3 in the non-working aluminum foil paper supply component 11 is not in any of the conditions of being used up, broken, and having joints, it means that the aluminum foil 3 in the non-working aluminum foil paper supply component 11 has been installed and is ready, and the aluminum foil 3 is not in any abnormal conditions such as being used up, broken, and having joints. Therefore, at this time, it can be determined that the non-working aluminum foil paper supply component 11 is ready and the subsequent switching action can be performed.

[0070] In actual use, the switching control device 2 can control the switching from a working aluminum foil supply component 11 to another non-working aluminum foil supply component 11 when the detection device 22 corresponding to a working aluminum foil supply component 11 detects that the aluminum foil 3 in the working aluminum foil supply component 11 is exhausted, broken, or has a joint, and the detection device 22 corresponding to an inoperative aluminum foil supply component 11 detects that the embossing roller 14 of the inoperative aluminum foil supply component 11 is in the initial position, and the aluminum foil 3 in the inoperative aluminum foil supply component 11 is not exhausted, broken, or has a joint.

[0071] It can be seen that based on the set switching control device 2, the aluminum foil paper supply system 10 can switch one aluminum foil paper supply component 11 to another aluminum foil paper supply component 11 when any of the situations such as paper running out, paper breaking and paper having joints occurs. This allows the aluminum foil paper supply system 10 to switch the two aluminum foil paper supply components 11 not only when the paper runs out, but also when the paper breaks and paper has joints. This can more reliably prevent abnormal aluminum foil 3 from entering the next process, thereby achieving a safer and more efficient packaging process.

[0072] In order to facilitate the detection device 22 to detect the paper exhaustion situation, see Figure 2 In some embodiments, the detection device 22 includes a paper-end detector 23. The paper-end detector 23 detects whether the aluminum foil paper 3 on the paper tray 12 has been used up. Figure 1 The paper end detector 23 can be arranged on the paper tray 12, and can determine whether the aluminum foil 3 is used up by detecting whether there is aluminum foil 3 on the paper tray 12. Figure 1 In the embodiment, the paper end detector 23 is arranged at the center of the paper tray 12, that is, the starting point of the aluminum foil 3. As an example, the paper end detector 23 is an electromagnetic induction detector. The electromagnetic induction detector uses the electromagnetic induction principle to detect whether a metal object exists, and converts the result into an electrical signal for output. When the paper end detector 23 is an electromagnetic induction detector, the paper end detector 23 can use the electromagnetic induction principle to detect whether there is still aluminum foil 3 on the paper tray 12, and when the aluminum foil 3 is detected on the paper tray 12, it is judged that the aluminum foil 3 has not been used up, and when the aluminum foil 3 is not detected on the paper tray 12, it is judged that the aluminum foil 3 has been used up.

[0073] In order to facilitate the detection device 22 to detect the paper breakage, see Figure 2 In some embodiments, the detection device 22 includes a paper break detector 24. The paper break detector 24 detects whether the aluminum foil 3 is broken. Figure 1 The paper break detector 24 can be arranged on the aluminum foil conveying path upstream of the paper cutter 16, and can determine whether the aluminum foil 3 is broken by detecting whether there is aluminum foil 3 at the location. Figure 1 In the embodiment, the paper break detector 24 is disposed between the embossing roller 14 and the paper tray 12. As an example, the paper break detector 24 is an electromagnetic induction detector. At this time, the paper break detector 24 uses the electromagnetic induction principle to detect whether the aluminum foil 3 exists at the location, and when the aluminum foil 3 is detected, it is determined that the aluminum foil 3 is not broken, and when the aluminum foil 3 is not detected, it is determined that the aluminum foil 3 is broken.

[0074] In order to facilitate the detection device 22 to detect the initial position of the embossing roller 14, see Figure 2In some embodiments, the detection device 22 includes an initial position detector 26. The initial position detector 26 detects whether the embossing roller 14 is in the initial position. Figure 1 The initial position detector 26 is arranged at the initial position, and determines whether the embossing roller 14 has reached the initial position by detecting the presence or absence of the embossing roller 14. As an example, the initial position detector 26 is an electromagnetic induction detector. At this time, the initial position detector 26 uses the electromagnetic induction principle to detect whether the embossing roller 14 has reached the initial position.

[0075] In order to facilitate the detection device 22 to detect the joint on the paper, see Figure 2 In some embodiments, the detection device 22 includes a paper joint detector 25. The paper joint detector 25 detects whether there is a joint on the aluminum foil 3. Figure 1 The paper joint detector 25 can be arranged on the aluminum foil conveying path upstream of the paper cutter 16 to determine whether the aluminum foil 3 is broken by detecting whether there is aluminum foil 3 at the location. Figure 1 In the embodiment, the paper break detector 24 is disposed between the embossing roller 14 and the paper tray 12. As an example, the paper break detector 24 is a color mark detector. The color mark detector can identify the color difference of an object by judging the intensity of the received light. Therefore, when the paper break detector 24 is a color mark detector, the paper break detector 24 can identify whether there is a joint on the aluminum foil 3 by judging the intensity of the received light.

[0076] It should be noted that Figure 1 Only the approximate arrangement positions of the paper end detector 23, the paper break detector 24 and the initial position detector 26 are shown, and the specific structures of the paper end detector 23, the paper break detector 24 and the initial position detector 26 are not shown.

[0077] In addition, it should be understood that the structure of the detection device 22 is not limited to the aforementioned embodiments. For example, as a variation, the paper end detector 23, the paper break detector 24 and the initial position detector 26 may also be other types of detectors such as photoelectric sensors or optical fiber sensors; or the paper joint detector may also be replaced by other devices capable of identifying joints such as a camera device.

[0078] When it is confirmed based on the detection result of the detection device 22 that switching is required and possible, the switching process can be started.

[0079] See also Figure 3 After the switching process is started, the device can be slowed down to the target speed to avoid problems such as too high speed, shortage of aluminum foil or blockage. After the device is slowed down to the target speed, the paper cutter 16 and the embossing roller 14 can be controlled to complete the switching process.

[0080] Among them, whether the paper cutter 16 and the embossing roller 14 in the two aluminum foil supply components 11 can be operated can be determined based on the detection result of the encoder 21, that is, the phase information detected by the encoder 21 can be used as the basis for the operation of the paper cutter 16 and the embossing roller 14.

[0081] Among them, reaching the action phase of the paper cutter 16 means that the paper cutter 16 can move, and reaching the action phase of the embossing roller 14 means that the embossing roller 14 can be engaged or disengaged. Therefore, when the encoder 21 detects that the action phase of the paper cutter 16 is reached, the paper cutter 16 can be controlled to cut the aluminum foil 3. When the encoder 21 detects that the action phase of the embossing roller 14 is reached, the embossing roller 14 can be controlled to engage or disengage.

[0082] In the process of switching from the working aluminum foil paper supply component 11 to the non-working aluminum foil paper supply component 11, after the equipment slows down to the target speed, the paper cutter 16 of the non-working aluminum foil paper supply component 11 is first controlled to cut the aluminum foil 3, and then the embossing roller 14 of the working aluminum foil paper supply component 11 is controlled to disengage, and the embossing roller 14 of the non-working aluminum foil paper supply component 11 is engaged, so that the original working aluminum foil paper supply component 11 no longer supplies aluminum foil paper 3 to the downstream, but the original non-working aluminum foil paper supply component 11 supplies aluminum foil paper 3 to the downstream, thereby realizing the switching from the working aluminum foil paper supply component 11 to the non-working aluminum foil paper supply component 11.

[0083] It is understood that in the present disclosure, the phase refers to the phase of the host. The encoder 21 can be an encoder provided by the packaging machine, which is electrically connected to the host, so that the host can be directly detected to obtain the phase information of the host. Specifically, the encoder 21 calculates the motion phase and speed based on the monitoring of the rotation angle and speed of the host, thereby realizing real-time monitoring of the running speed and phase.

[0084] When controlling the actions of the paper cutter 16 and the embossing roller 14, the switching control device 2 can control the actions of the paper cutter 16 and the embossing roller 14 by controlling the actions of the cutting control mechanism 17 and the embossing control mechanism 18. At this time, the switching control device 2 can be electrically connected to the cutting control mechanism 17 and the embossing control mechanism 18. For example, see Figure 2 When the cutting control mechanism 17 includes a cutting electromagnetic valve 172 and a cutting cylinder 171, the switching control device 2 can be electrically connected to the cutting electromagnetic valve 172, and the paper cutter 16 can be controlled to move by controlling the cutting electromagnetic valve 172 to connect or shut off the air path. When the embossing control mechanism 18 includes an embossing electromagnetic valve 182 and an embossing cylinder 181, the switching control device 2 can be electrically connected to the embossing electromagnetic valve 182, and the embossing roller 14 can be controlled to move by controlling the embossing electromagnetic valve 182 to connect or shut off the air path.

[0085] See also Figure 2 In the above embodiments, the switching control device 2 may include not only the encoder 21 and the two detection devices 22, but also an encoder board 28, an input-output board 29 and a controller 27. The encoder board 28 is electrically connected to the encoder 21. For example, the encoder 21 may be connected to the encoder board 28 via a dedicated connection line, so that the encoder 21 may transmit the detection result to the encoder board 28 for processing by the encoder board 28. The input-output board 29 is electrically connected to the two detection devices 22 to receive the detection result of the detection device 22. The controller 27 is electrically connected to the encoder board 28 and the input-output board 29, and controls the two aluminum foil supply components 11 to switch to work according to the detection results of the encoder 21 and the two detection devices 22. The controller 27 may be connected to the encoder board 28 and the input-output board 29 via a backplane bus to achieve signal transmission.

[0086] Among them, the controller 27 can be implemented by various computing devices or computer systems. The memory can be a high-speed RAM memory or a non-volatile memory, etc. The memory can also be a memory array. The memory may also be divided into blocks, and the blocks can be combined into virtual volumes according to certain rules. The processor can be a central processing unit CPU, or an application-specific integrated circuit ASIC (Application Specific Integrated Circuit), or one or more integrated circuits configured to implement the vehicle control method of each embodiment. In some embodiments, the controller 27 is a controller that comes with the system, specifically a controller of the CPU of the packaging machine, which can process the input signal at high speed based on the GDL (Geometric Description Language, a parameterized programming language) program and output the control result.

[0087] Based on the aluminum foil paper supply system 10 of the above embodiments, see Figure 3 , the control method provided by the present disclosure includes:

[0088] During the operation of one aluminum foil supply assembly 11, according to the detection result of the detection device 22 corresponding to the working aluminum foil supply assembly 11, it is determined whether it is necessary to switch from the working aluminum foil supply assembly 11 to another non-working aluminum foil supply assembly 11;

[0089] When it is necessary to switch from the working aluminum foil supply component 11 to another non-working aluminum foil supply component 11, it is determined whether the aluminum foil 3 of the non-working aluminum foil supply component 11 is ready according to the detection result of the detection device 22 corresponding to the non-working aluminum foil supply component 11;

[0090] When the aluminum foil 3 of the inoperative aluminum foil supply assembly 11 is ready, the device is controlled to slow down, and when the device slows down to the target speed and the encoder 21 detects that the action phase of the paper cutter 16 of the operating aluminum foil supply assembly 11 and the embossing rollers 14 of the two aluminum foil supply assemblies 11 has been reached, the paper cutter 16 of the operating aluminum foil supply assembly 11 is controlled to cut the aluminum foil 3, and the embossing roller 14 of the operating aluminum foil supply assembly 11 is controlled to disengage, and the embossing roller 14 of the inoperative aluminum foil supply assembly 11 is controlled to engage, so that the operating aluminum foil supply assembly 11 is switched to the inoperative aluminum foil supply assembly 11.

[0091] Among them, see Figure 3 According to the detection result of the detection device 22 corresponding to the working aluminum foil supply component 11, determining whether it is necessary to switch from the working aluminum foil supply component 11 to the non-working aluminum foil supply component 11 may include:

[0092] When the detection device 22 corresponding to the working aluminum foil paper supply component 11 detects that the aluminum foil 3 in the working aluminum foil paper supply component 11 is at least one of exhausted, broken and has a joint, it is determined that it is necessary to switch from the working aluminum foil paper supply component 11 to the non-working aluminum foil paper supply component 11.

[0093] According to the detection result of the detection device 22 corresponding to the non-operating aluminum foil supply component 11, judging whether the aluminum foil 3 of the non-operating aluminum foil supply component 11 is ready may include:

[0094] When the detection device 22 corresponding to the inoperative aluminum foil paper supply component 11 detects that the embossing roller 14 of the inoperative aluminum foil paper supply component 11 is in the initial position, and the aluminum foil paper 3 in the inoperative second aluminum foil paper supply component 11 is not exhausted, broken, or has a joint, it is determined that the aluminum foil paper 3 of the inoperative aluminum foil paper supply component 11 is ready.

[0095] Also, see Figure 3 When the device is decelerated to the target speed and the encoder 21 detects that the action phase of the paper cutter 16 of the working aluminum foil paper supply assembly 11 and the embossing rollers 14 of the two aluminum foil paper supply assemblies 11 has been reached, the paper cutter 16 of the working aluminum foil paper supply assembly 11 is controlled to cut the aluminum foil 3, and the embossing roller 14 of the working aluminum foil paper supply assembly 11 is controlled to disengage, and the embossing roller 14 of the non-working aluminum foil paper supply assembly 11 is controlled to engage, which may include:

[0096] When the device is decelerated to the target speed, it is determined whether the action phase of the paper cutter 16 of the working aluminum foil paper supply assembly 11 has been reached according to the detection result of the encoder 21;

[0097] When the paper cutter 16 of the working aluminum foil supply assembly 11 has reached the action phase, the paper cutter 16 in the working aluminum foil supply assembly 11 is controlled to cut the aluminum foil 3;

[0098] After the paper cutter 16 in the working aluminum foil supply assembly 11 cuts the aluminum foil 3, it is determined whether the action phase of the embossing rollers 14 of the two aluminum foil supply assemblies 11 has been reached according to the detection result of the encoder 21;

[0099] When the action phase of the embossing rollers 14 of the two aluminum foil paper supply components 11 is reached, the embossing roller 14 of the working aluminum foil paper supply component 11 is controlled to disengage, and the embossing roller 14 of the non-working aluminum foil paper supply component 11 is controlled to engage.

[0100] See also Figure 3 In some embodiments, the paper cutter 16 of the aluminum foil supply assembly 11 is controlled to cut the aluminum foil 3, and the embossing roller 14 of the aluminum foil supply assembly 11 is controlled to disengage, and the embossing roller 14 of the non-operating aluminum foil supply assembly 11 is engaged, including:

[0101] The cut-off solenoid valve 172 of the aluminum foil paper supply assembly 11 is controlled to operate, so that the paper cutter 16 of the aluminum foil paper supply assembly 11 cuts the aluminum foil paper 3;

[0102] The embossing solenoid valve 182 of the working aluminum foil paper supply assembly 11 is controlled to operate, so that the embossing roller 14 in the working aluminum foil paper supply assembly 11 is disengaged;

[0103] The embossing solenoid valve 182 of the non-operating aluminum foil paper supply assembly 11 is controlled to operate so that the embossing roller 14 of the non-operating aluminum foil paper supply assembly 11 is engaged.

[0104] Also, see Figure 3 In some embodiments, the control method includes:

[0105] When the working aluminum foil supply component 11 needs to be switched to the non-working aluminum foil supply component 11, but the aluminum foil 3 in the non-working aluminum foil supply component 11 is not ready, an alarm is issued and / or the machine is shut down.

[0106] Whether the aluminum foil 3 in the non-operating aluminum foil supply assembly 11 is ready can be determined based on the detection result of the detection device 22. When the detection device 22 detects that the embossing roller 14 is not in the initial position, or detects that the aluminum foil 3 is exhausted, broken or connected, it is determined that the aluminum foil 3 is not ready.

[0107] In order to facilitate the alarm, the aluminum foil supply system 10 may include an alarm (not shown). When one of the two aluminum foil supply assemblies 11 needs to switch to the other, but the aluminum foil 3 in the other is not ready, the alarm sounds an alarm to notify the staff in time.

[0108] Next, combine Figure 1-3 The illustrated embodiments further illustrate the present disclosure.

[0109] like Figure 1-3 As shown, in this embodiment, the aluminum foil supply system 10 is the aluminum foil supply system of the GD-X2 packaging machine, which includes two aluminum foil supply components 11, namely the aluminum foil supply component 11 on the left and the aluminum foil supply component 11 on the right. The two aluminum foil supply components 11 have the same structure and both include a paper tray 12, an embossing roller 14, an embossing solenoid valve 182, a paper cutter 16 and a cut-off solenoid valve 172.

[0110] In addition, the aluminum foil paper supply system 10 further includes an encoder 21, an encoder board 28, two detection devices 22, an input-output board 29, and a controller 27. The two detection devices 22 correspond to the two aluminum foil paper supply assemblies 11 one by one, and the two detection devices 22 each include a paper end detector 23, a paper break detector 24, a paper joint detector 25, and an initial position detector 26. The two groups of paper end detectors 23, paper break detectors 24, paper joint detectors 25, and initial position detectors 26 are electrically connected to the controller 27 through the input-output board 29. The encoder 21 is electrically connected to the controller 27 through the encoder board 28. At the same time, the controller 27 is electrically connected to the embossing solenoid valve 182 and the cut-off solenoid valve 172.

[0111] The encoder 21 uses the Lika AST680 / GY-10 / S431 encoder, which is the encoder of the packaging machine and can directly obtain the phase information of the host. In actual work, the encoder 21 transmits the monitored position angle information to the encoder board 28 in real time through the bus. After the encoder board 28 processes the signal, it is further transmitted to the controller 27 of the packaging machine through the backplane bus as a signal condition for program execution.

[0112] The two groups of paper end detectors 23, paper break detectors 24 and initial position detectors 26 all use BALLUFF BES01C7 detectors. The BALLUFF BES01C7 detector can detect the presence of metal objects using the principle of electromagnetic induction and convert the results into electrical signals for output. In this case, when the paper end detector 23, paper break detector 24 and initial position detector 26 detect metal objects, the output end outputs a +24V DC voltage, and when no metal objects are detected, the output end outputs 0V. The detection results of the paper end detector 23, paper break detector 24 and initial position detector 26 are transmitted to the input and output board 29, and then transmitted to the controller 27 of the packaging machine by the input and output board 29.

[0113] The two paper joint detectors 25 are both DATASENSOR TLu-315 detectors, which can identify the color difference of objects by judging the intensity of received light, thereby identifying the existence of aluminum foil paper joints. The detection results of the paper joint detectors 25 are transmitted to the input and output board 29, and then transmitted to the controller 27 of the packaging machine by the input and output board 29.

[0114] The controller 27 receives signals from the input-output board 29 and the encoder board 28, processes the signals, and transmits the results as output signals to the embossing solenoid valve 182 and the cut-off solenoid valve 172 to control the actions of the embossing roller 14 and the paper cutter 16. The controller 27 and the embossing solenoid valve 182 and the cut-off solenoid valve 172 can be electrically connected through the input-output board 29, so that the controller 27 can transmit the results to the embossing solenoid valve 182 and the cut-off solenoid valve 172 through the input-output board 29.

[0115] Next, taking the situation where the aluminum foil supply component 11 on the left is currently working (at this time, the working aluminum foil supply component 11 is the aluminum foil supply component 11 on the left, and the non-working aluminum foil supply component 11 is the aluminum foil supply component 11 on the right) as an example, the switching process of the two aluminum foil supply components 11 in this embodiment is introduced.

[0116] like Figure 3As shown, when any one of the paper end detector 23, the paper break detector 24 and the paper joint detector 25 on the left is triggered, it is determined that the aluminum foil paper supply component 11 on the left needs to be switched to the aluminum foil paper supply component 11 on the right. At this time, it is determined whether the aluminum foil paper 3 in the aluminum foil paper supply component 11 on the right is ready. If the aluminum foil paper 3 in the aluminum foil paper supply component 11 on the right is not ready, the machine is shut down and an alarm is sounded. If the aluminum foil paper 3 in the aluminum foil paper supply component 11 on the right is ready (that is, the initial position detector 26 on the right is triggered, and the paper end detector 23 and the paper break detector 24 on the right are not triggered, and there is no signal input to the paper joint detector 25), it is determined that the switching process can be started.

[0117] When starting the switching process, first control the device to slow down to the target speed. After the device slows down to the target speed, when the encoder 21 detects that the host reaches the action phase of the paper cutter 16, the cut-off solenoid valve 172 on the left is controlled to be energized to make the paper cutter 16 on the left actuate; when the encoder 21 detects that the host reaches the switching phase of the embossing roller 14, the embossing solenoid valve 182 on the left is controlled to be de-energized, and the embossing solenoid valve 182 on the right is energized, so that the embossing roller 14 on the left is disengaged and the embossing roller 14 on the right is engaged, so that the aluminum foil paper 3 is automatically switched from the left side to the right side, completing the switching process.

[0118] The switching process of the right aluminum foil paper supply assembly 11 to the left aluminum foil paper supply assembly 11 is similar to the above process, so it will not be repeated here.

[0119] It can be seen that the switching control device 2 of this embodiment can realize real-time detection of various abnormal conditions of the aluminum foil 3, and when it is found that there is a need for switching, the automatic switching of the aluminum foil can be realized by controlling the actuator (including the embossing roller 14 and the paper cutter 16), or a shutdown alarm signal can be output, which has a high degree of automation and saves time and effort. In addition, the switching control device 2 of this embodiment, its controller 27, encoder 21, encoder board 28 and input and output board 29 are all built-in to the system, so it can be directly embedded in the control system of the GD-X2 packaging machine to achieve a high degree of integration with the original equipment.

[0120] The above description is only an exemplary embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
