The aluminum foil paper supply system is used for supplying aluminum foil paper, embossing and cutting the aluminum foil paper in the aluminum foil paper supply process to form a single aluminum foil paper with embossing, and the single aluminum foil paper is supplied to a subsequent link for use.
Fig. 1 to 3 exemplarily show an aluminum-foil paper supply system of the present disclosure and a control method thereof.
Referring to fig. 1, an aluminum-foil feeding system 10 includes an aluminum-foil feeding apparatus 1, and the aluminum-foil feeding apparatus 1 includes two aluminum-foil feeding assemblies 11. The two aluminum-foil paper supply units 11 are arranged side by side, for example, in the left-right direction. The two aluminum foil paper feeding assemblies 11 have the same structure and each include a paper tray 12, an embossing mechanism 1b, and a cutting mechanism 1 a. The embossing mechanism 1b includes an embossing roll 14. The cutting mechanism 1a includes a cutter 16. For the sake of convenience, the two aluminum-foil paper feeding assemblies 11 may be named with "left" and "right" or "first" and "second", respectively, and the two aluminum-foil papers may be assigned to the components of the assemblies 11, such as the paper tray 12, the embossing mechanism 1b, the cutting mechanism 1a, the embossing roller 14, and the cutter 16.
In the same aluminum-foil paper feeding unit 11, the paper tray 12, the emboss roller 14, and the cutter 16 are arranged in this order along the conveying direction of the aluminum-foil paper 3. Wherein, the paper tray 12 is used for rolling the aluminum foil paper 3. The embossing roller 14 embosses the aluminum foil 3 protruding from the paper tray 12. The cutter 16 cuts the aluminum foil 3. A plurality of guide rollers 13 are provided between the sheet tray 12 and the emboss roller 14 and between the emboss roller 14 and the cutter 16 for guiding.
In operation, the aluminum foil 3 wound on the paper tray 12 passes through the guide roller 13 in a predetermined route and sequentially reaches the emboss roller 14 and the cutter 16.
At the embossing roller 14, the embossing roller 14 rolls the aluminum foil 3, and patterns are pressed at the preset position of the aluminum foil 3, so that the aluminum foil 3 is embossed, the product packaging quality is improved, the anti-counterfeiting identification capability of the product is improved, and the enterprise image and the popularity are improved. Referring to fig. 2, in some embodiments, the embossing mechanism 1b includes an embossing control mechanism 18 in addition to the embossing roll 14, and the embossing control mechanism 18 is drivingly connected to the embossing roll 14 to drive the embossing roll 14 to disengage or engage. The embossing roller 14 rolls the aluminum foil paper 3 during meshing, so as to achieve the purpose of embossing. 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 in driving connection with the embossing roll 14. The embossing solenoid valve 182 is disposed 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 stretching of the embossing cylinder 181, and further controls the disengagement or engagement of the embossing roller 14. Disengagement and engagement of patterned roll 14 refers to disengagement and engagement between a patterned roll, shown in phantom lines in fig. 1, and a non-patterned roll, shown in solid lines.
At the paper cutter 16, the paper cutter 16 acts to cut the aluminum-foil paper 3 into sheets meeting the requirements for use in the subsequent links. Referring to fig. 2, in some embodiments, the cutting mechanism 1a includes a cutting control mechanism 17 in addition to the guillotine 16, and the cutting control mechanism 17 is drivingly connected to the guillotine 16 to drive the guillotine 16 to perform cutting. Specifically, in some embodiments, the shutoff control mechanism 17 includes a shutoff solenoid valve 172 and a shutoff cylinder 171. The cutting cylinder 171 is drivingly connected to the guillotine 16. The cutting solenoid valve 172 is provided in the air path of the cutting cylinder 171, and controls opening and closing of the air path of the cutting cylinder 171 to control expansion and contraction of the cutting cylinder 171, and further control whether the cutter 16 performs a cutting operation.
In practical use, the two aluminum-foil supply assemblies 11 respectively and independently supply the aluminum-foil 3, and the two assemblies work in a switching manner, that is, when one aluminum-foil supply assembly 11 supplies the aluminum-foil 3, the other aluminum-foil 3 does not supply the aluminum-foil 3, and when necessary, the working aluminum-foil supply assembly 11 is switched to the other aluminum-foil supply assembly 11, and the other aluminum-foil supply assembly 11 is changed to convey the aluminum-foil 3 to a subsequent link.
To facilitate the switching of the two aluminium foil supply assemblies 11, in the embodiment of the present disclosure, the aluminium foil supply system 10 further comprises a switching control device 2, see fig. 1-3. The switching control means 2 comprise an encoder 21 and two detection means 22. The encoder 21 detects whether the operation phase of the cutter 16 and the emboss roller 14 is reached. Two detection devices 22 are in one-to-one correspondence with the two aluminum foil supply assemblies 11. The detection device 22 detects whether the aluminum foil 3 in the aluminum foil supply assembly 11 is used up, broken, or has a splice, and detects whether the emboss roller 14 is in the initial position. The switching control device 2 controls the two aluminum-foil paper supply units 11 to operate in a switching manner based on the detection results of the encoder 21 and the two detection devices 22.
Based on the switching control device 2, the aluminum-foil paper supply system 10 can control the two aluminum-foil paper supply assemblies 11 to work in a switching manner, so as to realize the automatic switching of the two aluminum-foil paper supply assemblies 11, thereby effectively improving the switching efficiency and reducing the labor intensity of operators compared with the manual switching manner in the related art.
The detection device 22 detects whether the aluminum-foil paper 3 in the aluminum-foil paper supply assembly 11 is used up, broken, or has a joint, and can determine whether the aluminum-foil paper supply assembly 11 has abnormal conditions such as paper use-up, paper breakage, and a joint on the paper, and the corresponding detection result can be used as a basis for determining whether switching is required or not and whether switching is possible. For example, if the corresponding detection device 22 detects that there is any one of a paper-out, a paper break, and a paper splice in the operating aluminum-foil paper supply assembly 11, it indicates that there is an abnormal condition in the aluminum-foil paper supply assembly 11, and it is necessary to switch to another aluminum-foil paper supply assembly 11. For another example, if the corresponding detection device 22 detects that there is any one of a paper-out, a paper break, and a paper splice in the non-operating aluminum-foil supply assembly 11, it indicates that there is also an abnormal condition in the aluminum-foil 3 in the aluminum-foil supply assembly 11, and the aluminum-foil supply assembly 11 is not ready yet and cannot be switched.
The detecting device 22 detects whether the embossing roller 14 is in the initial position, and is mainly used to determine whether the non-operating aluminum foil supply assembly 11 is ready in combination with the detection result of the detecting device 22 on the aluminum foil 3. The initial position of the embossing roller 14 refers to the position of the embossing roller 14 when the pattern on the embossing roller 14 corresponds to the pattern to be pressed on the aluminum foil 3. If it is detected that the embossing roller 14 is already in the initial position, it indicates that the aluminium foil 3 has been threaded into position. Therefore, by detecting whether the emboss roller 14 is already at the initial position, it is possible to judge whether the aluminum foil 3 has been threaded into position. In this way, when the detection device 22 detects that the embossing roller 14 in the non-operating aluminum foil supply assembly 11 is in the initial position and there is no exhaustion, breakage or connection of the aluminum foil 3 in the non-operating aluminum foil supply assembly 11, it indicates that the aluminum foil 3 in the non-operating aluminum foil supply assembly 11 is ready to be installed and there is no abnormal situation such as exhaustion, breakage or connection of the aluminum foil 3, so that it can be determined that the non-operating aluminum foil supply assembly 11 is ready at this time and the subsequent switching operation can be performed.
In practical use, the switching control device 2 may control the switching from the one active aluminum-foil supply assembly 11 to the other inactive aluminum-foil supply assembly 11 when the detecting device 22 corresponding to the one active aluminum-foil supply assembly 11 detects that at least one of the exhaustion, breakage and presence of a joint of the aluminum-foil 3 in the one active aluminum-foil supply assembly 11 exists, and the detecting device 22 corresponding to the one inactive aluminum-foil supply assembly 11 detects that the embossing roller 14 of the one inactive aluminum-foil supply assembly 11 is in the initial position and that there is no one of the exhaustion, breakage and presence of a joint of the aluminum-foil 3 in the one inactive aluminum-foil supply assembly 11.
It can be seen that, based on the switching control device 2, the aluminum-foil paper supply system 10 can switch one aluminum-foil paper supply assembly 11 to another aluminum-foil paper supply assembly 11 when any one of paper exhaustion, paper breakage and paper joint occurs, so that the aluminum-foil paper supply system 10 can not only switch two aluminum-foil paper supply assemblies 11 when the paper exhaustion problem occurs, but also switch two aluminum-foil paper supply assemblies 11 when the paper breakage and paper joint problem occur, thereby more reliably preventing the abnormal aluminum-foil paper 3 from entering the next procedure, and realizing a safer and more efficient packaging process.
In order to facilitate the detection of the paper-out condition by the detection device 22, referring to fig. 2, in some embodiments, the detection device 22 includes a paper-out detector 23. The paper-end detector 23 detects whether the aluminum foil paper 3 on the paper tray 12 has been used up. Referring to fig. 1, a paper-end detector 23 may be provided on the paper tray 12 and may determine whether the aluminum-foil paper 3 has been used up by detecting whether the aluminum-foil paper 3 is present on the paper tray 12. For example, in fig. 1, the paper-end detector 23 is disposed at the center of the paper tray 12, that is, the start of the aluminum foil paper 3. As an example, the paper-end detector 23 is an electromagnetic induction detector. The electromagnetic induction detector detects whether a metal object exists or not by utilizing the electromagnetic induction principle, converts the result into an electric signal and outputs the electric signal. When the paper-end detector 23 is an electromagnetic induction detector, the paper-end detector 23 can detect whether the aluminum-foil paper 3 still exists on the paper tray 12 by using the principle of electromagnetic induction, and when the aluminum-foil paper 3 on the paper tray 12 is detected, it is determined that the aluminum-foil paper 3 is not used up, and when the aluminum-foil paper 3 on the paper tray 12 is not detected, it is determined that the aluminum-foil paper 3 is used up.
To facilitate detection of a paper break by the detection device 22, referring to fig. 2, in some embodiments, the detection device 22 includes a paper break detector 24. The paper break detector 24 detects whether the aluminum foil paper 3 has broken. Referring to fig. 1, a paper breakage detector 24 may be provided on the aluminum foil transport path upstream of the cutter 16 to determine whether the aluminum foil 3 is broken by detecting the presence of the aluminum foil 3 at the position. For example, in fig. 1, the paper break detector 24 is disposed between the emboss 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 breakage detector 24 detects whether the aluminum-foil paper 3 exists at the position by using the electromagnetic induction principle, and when the aluminum-foil paper 3 is detected, it determines that the aluminum-foil paper 3 is not broken, and when the aluminum-foil paper 3 is not detected, it determines that the aluminum-foil paper 3 is broken.
To facilitate detection of the initial position of the patterned roll 14 by the detection device 22, referring to fig. 2, in some embodiments, the detection device 22 includes an initial position detector 26. The initial position detector 26 detects whether the emboss roller 14 is at an initial position. Referring to fig. 1, an initial position detector 26 is provided at an initial position to determine whether the emboss roller 14 has reached the initial position by detecting the presence or absence of the emboss roller 14. As an example, the initial position detector 26 is an electromagnetic induction detector. At this time, the initial position detector 26 detects whether the emboss roller 14 has reached the initial position using the principle of electromagnetic induction.
To facilitate detection of the splice on the paper by the detection device 22, referring to fig. 2, in some embodiments the detection device 22 includes a paper splice detector 25. The paper joint detector 25 detects the presence or absence of a joint on the aluminum foil 3. Referring to fig. 1, a paper joint detector 25 may be provided on the aluminum foil transport path upstream of the cutter 16 to determine whether the aluminum foil 3 is broken by detecting the presence of the aluminum foil 3 at the position. For example, in fig. 1, the paper break detector 24 is disposed between the emboss roller 14 and the paper tray 12. As an example, the paper break detector 24 is a color scale detector. The color scale detector may identify a color difference of the object by judging the intensity of the received light. Therefore, when the paper breakage detector 24 is a color scale detector, the paper breakage detector 24 can identify the presence or absence of a joint on the aluminum foil 3 by judging the intensity of the received light.
Fig. 1 shows only the approximate positions of the paper-end detector 23, the paper break detector 24, and the home position detector 26, and does not show the specific configurations of the paper-end detector 23, the paper break detector 24, and the home position detector 26.
In addition, it should be understood that the structure of the detection device 22 is not limited to the foregoing embodiments. For example, as a modification, the paper-end detector 23, the paper break detector 24, and the initial position detector 26 may employ other types of detectors such as a photoelectric sensor or an optical fiber sensor; alternatively, the paper jam detector may be replaced with another device capable of recognizing a jam, such as an image pickup device.
When it is confirmed that a handover is required and possible based on the detection result of the detection means 22, then the start of the handover procedure may be started.
Referring to fig. 3, after the switching process is started, the speed of the device may be reduced to a target speed to avoid the problems of shortage or blockage of the aluminum foil due to over-high speed. After the apparatus is slowed down to the target speed, the guillotine 16 and the embossing roll 14 can be controlled to complete the switching process.
Whether the cutter 16 and the emboss roller 14 of the two aluminum-foil paper supply units 11 can be operated or not 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 cutter 16 and the emboss roller 14.
Here, reaching the action phase of the cutter 16 means that the cutter 16 can act; and the phase of the action of the emboss roller 14 is reached, meaning that the emboss roller 14 can be engaged or disengaged. Therefore, when the encoder 21 detects that the phase of the movement of the cutter 16 is reached, the cutter 16 can be controlled to cut the aluminum foil 3. When the encoder 21 detects that the phase of the motion of the emboss roller 14 is reached, the emboss roller 14 can be controlled to be engaged or disengaged.
In the process of switching from the working aluminum-foil paper supply assembly 11 to the non-working aluminum-foil paper supply assembly 11, after the device is decelerated to a target speed, the paper cutter 16 of the non-working aluminum-foil paper supply assembly 11 is controlled to cut off the aluminum-foil paper 3, then 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 engaged, so that the originally working aluminum-foil paper supply assembly 11 does not supply the aluminum-foil paper 3 downstream, but the originally non-working aluminum-foil paper supply assembly 11 supplies the aluminum-foil paper 3 downstream, and the working aluminum-foil paper supply assembly 11 switches to the non-working aluminum-foil paper supply assembly 11.
It is understood that in this disclosure, phase refers to the phase of the host. The encoder 21 may be an encoder of the packaging machine itself, and is electrically connected to the host machine, so that the host machine can be directly detected to obtain phase information of the host machine. Specifically, the encoder 21 calculates the motion phase and speed based on monitoring the rotation angle and speed of the host, thereby realizing real-time monitoring of the operation speed and phase.
When controlling the operation of the cutter 16 and the emboss roller 14, the switching control device 2 can control the operation of the cutter 16 and the emboss roller 14 by controlling the operation of the cutting control mechanism 17 and the emboss control mechanism 18. At this time, the switching control device 2 may be electrically connected to the cutting control mechanism 17 and the embossing control mechanism 18. For example, referring to fig. 2, when the cutting control mechanism 17 includes a cutting solenoid 172 and a cutting cylinder 171, the switching control device 2 may be electrically connected to the cutting solenoid 172 to control the operation of the cutter 16 by controlling the cutting solenoid 172 to open or close the air passage. When the embossing control mechanism 18 includes the embossing solenoid valve 182 and the embossing cylinder 181, the switching control device 2 may be electrically connected to the embossing solenoid valve 182 to control the embossing roller 14 by controlling the embossing solenoid valve 182 to open or close the air path.
Referring to fig. 2, in the foregoing embodiments, the switching control device 2 may include an encoder board 28, an input-output board 29, and a CPU27 in addition to the encoder 21 and the two detection devices 22. The encoder board 28 is electrically connected to the encoder board 21, for example, the encoder board 21 may be connected to the encoder board 28 by a dedicated connection line, so that the encoder board 28 can transmit the detection result to the encoder board 28 to be processed by the encoder board 28. The input-output board 29 is electrically connected to the two detection devices 22 to receive the detection results of the detection devices 22. The controller of the CPU27 is electrically connected to the encoder board 28 and the input/output board 29, and controls the two aluminum foil supply units 11 to operate in a switching manner based on the detection results of the encoder 21 and the two detection devices 22. The CPU27 and the encoder board 28 and the input-output board 29 may be connected by a backplane bus to enable signal transfer.
Wherein the controller may be implemented by various computing devices or computer systems. The memory may be a high-speed RAM memory or a non-volatile memory (non-volatile memory) or the like. The memory may also be a memory array. The storage may also be partitioned and the blocks may be combined into virtual volumes according to certain rules. The processor may be a central processing unit CPU, or an application Specific Integrated circuit asic, or one or more Integrated circuits configured to implement the control method of the vehicle of the embodiments. In some embodiments, the CPU27 is a CPU of a system, specifically, a CPU of a packaging machine, and may perform high-speed processing on an input signal based on a GDL (Geometric Description Language) program and output a control result.
Based on the foregoing aluminum-foil paper supply system 10 of each embodiment, referring to fig. 3, the control method provided by the present disclosure includes:

The present disclosure will be further described with reference to the embodiments shown in fig. 1-3.
As shown in fig. 1 to 3, in this embodiment, the aluminum foil supply system 10 is an aluminum foil supply system of a GD-X2 packing machine, which includes two aluminum foil supply units 11, a left aluminum foil supply unit 11 and a right aluminum foil supply unit 11, respectively, and the two aluminum foil supply units 11 have the same structure and each include a paper tray 12, an emboss roller 14, an emboss solenoid valve 182, a cutter 16, and a cut-off solenoid valve 172.
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 CPU 27. Two detection devices 22 are in one-to-one correspondence with the two aluminum foil paper supply assemblies 11, and each of the two detection devices 22 includes a paper end detector 23, a paper break detector 24, a paper joint detector 25, and an initial position detector 26. The two sets of paper-end detector 23, paper break detector 24, paper splice detector 25, and home position detector 26 are electrically connected to the CPU27 through the input/output board 29. The encoder 21 is electrically connected to the CPU27 through an encoder board 28. Meanwhile, the CPU27 is electrically connected to the embossing solenoid valve 182 and the cutting solenoid valve 172.
The encoder 21 adopts a lika AST680/GY-10/S431 type encoder which is an encoder carried by the packing machine and can directly acquire the phase information of the host. In actual operation, the encoder 21 transmits the monitored position angle information to the encoder board 28 in real time by way of a bus. The encoder board 28 processes the signal and transmits the processed signal to the CPU27 of the packaging machine through the backplane bus, and the processed signal is used as a signal condition for program execution.
Both sets of the paper-end detector 23, the paper-break detector 24, and the home position detector 26 employ a BALLUFF BES01C7 detector. The BALLUFF BES01C7 detector can detect the existence of metal objects by utilizing the principle of electromagnetic induction and convert the result into an electric signal to be output. In this case, the paper-end detector 23, the paper break detector 24, and the home position detector 26 output a dc voltage of +24V at the output terminal when a metal object is detected, and 0V at the output terminal when a metal object is not detected. The detection results of the paper-end detector 23, the paper break detector 24, and the home position detector 26 are transmitted to the input/output board 29, and are transmitted from the input/output board 29 to the CPU27 of the packaging machine itself.
The two paper splice detectors 25 each employ a DATASENSOR TLu-315 detector that functions to identify the presence of an aluminum foil splice by determining the intensity of the received light to identify the color difference of the object. The detection result of the paper jam detector 25 is transmitted to the input/output board 29, and is transmitted from the input/output board 29 to the CPU27 provided in the packaging machine.
The CPU27 receives signals from the input-output board 29 and the encoder board 28 through its controller, processes these signals, and transmits the results as output signals to the embossing solenoid valve 182 and the cutting solenoid valve 172 to control the embossing roll 14 and the cutter 16 to operate. The CPU27 and the embossing solenoid valve 182 and the cutting solenoid valve 172 may be electrically connected through the input-output board 29 so that the CPU27 may transmit the results to the embossing solenoid valve 182 and the cutting solenoid valve 172 through the input-output board 29.
Next, the switching process of the two aluminum-foil supply units 11 in this embodiment will be described by taking as an example the case where the currently left aluminum-foil supply unit 11 is operating (in this case, the operating aluminum-foil supply unit 11 is the left aluminum-foil supply unit 11, and the non-operating aluminum-foil supply unit 11 is the right aluminum-foil supply unit 11).
As shown in fig. 3, when any one of the left paper-end detector 23, the paper-breakage detector 24, and the paper-joint detector 25 is triggered, it is determined that switching from the left aluminum-foil supply assembly 11 to the right aluminum-foil supply assembly 11 is required, at which time, it is determined whether the aluminum foils 3 in the right aluminum-foil supply assembly 11 are ready, if the aluminum foils 3 in the right aluminum-foil supply assembly 11 are not ready, it is stopped and an alarm is issued, and if the aluminum foils 3 in the right aluminum-foil supply assembly 11 are ready (i.e., the right initial-position detector 26 is triggered, while the right paper-end detector 23 and the paper-breakage detector 24 are not triggered, and the paper-joint detector 25 has no signal input), it is determined that it is possible to start the switching process.
When the switching process is started, firstly controlling the equipment to decelerate to make the equipment decelerate to a target speed, and after the equipment decelerates to the target speed, controlling the left cutting electromagnetic valve 172 to be electrified to make the left paper cutter 16 act when the encoder 21 detects that the host reaches the action phase of the paper cutter 16; when the encoder 21 detects that the main machine reaches the switching phase of the embossing rollers 14, the left embossing solenoid valve 182 is controlled to be powered off, the right embossing solenoid valve 182 is powered on, the left embossing roller 14 is disconnected, the right embossing roller 14 is meshed, and the aluminum foil paper 3 is automatically switched from the left side to the right side, so that the switching process is completed.
The switching process of the right aluminum-foil feeding assembly 11 to the left aluminum-foil feeding assembly 11 is similar to the above-mentioned process, and therefore, the description thereof is omitted.
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 paper 3, and when a situation that switching is required is found, automatic switching of the aluminum foil paper can be realized by controlling the execution mechanism (including the embossing roller 14 and the paper cutter 16), or a stop alarm signal can be output, so that the degree of automation is high, and time and labor are saved. In the switching control device 2 of the present embodiment, the CPU27, the encoder 21, the encoder board 28, and the input/output board 29 are all system-owned, and therefore, the switching control device can be directly incorporated into the control system of the GD-X2 packaging machine, and can achieve high integration with the original equipment.
The above description is only exemplary of the present disclosure and is not intended to limit the present disclosure, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure.
