Description

Technical Field

[0001] This application relates to the technical field of the opening control of the VE rear door of a cigarette making machine, and particularly relates to a VE rear door interlocking device for a cigarette making machine. Background Art

[0002] When the VE silk storage bin of the ZJ118 cigarette making machine needs to be opened and closed during equipment maintenance, it is controlled electrically. The control schematic diagram is as Figure 1 shown. A knob switch 1-2 is provided on the control circuit 1-1. The on-off of the control circuit 1-1 is realized through the knob switch 1-2. When the control circuit 1-1 is connected, the control module of the equipment receives a signal, and the equipment enters the maintenance mode, stops and opens the VE silk storage bin. After the maintenance is completed, the VE silk storage bin is closed again, and then the control circuit 1-1 is disconnected through the knob switch 1-2. The equipment exits the maintenance mode and can be normally started for production. In practice, the bottom of the VE silk storage bin is hinged to the equipment. When the VE silk storage bin is opened, it is opened in a way that the upper part tilts outwards. There is also a VE rear door outside the VE silk storage bin. Opening the VE rear door can perform operations such as local maintenance inside the equipment. The opening and closing operations of the VE rear door and the VE silk storage bin are independent of each other. When the operator stands beside the knob switch 1-2 to operate, the VE rear door cannot be observed, and it is impossible to know whether the VE rear door is in the open state or the closed state. If the VE rear door is in the open state, when the VE silk storage bin is opened by tilting outwards, the VE rear door will be pressed against the ground and deformed, affecting subsequent normal production. Summary of the Utility Model

[0003] The purpose of this application is to provide a VE rear door interlocking device for a cigarette making machine. This VE rear door interlocking device for a cigarette making machine can control the opening of the VE silk storage bin according to the opening state of the VE rear door, and the VE silk storage bin can only be opened when the VE rear door is in the closed state, thus effectively solving the deficiencies existing in the prior art.

[0004] To this end, the embodiment of this application provides a VE rear door interlocking device for a cigarette making machine, including:

[0005] A control circuit for transmitting a signal to the control module of the cigarette making machine to enable the cigarette making machine to enter the maintenance mode. The control circuit is provided with an input end and an output end, and the output end of the control circuit is connected to the control module of the cigarette making machine;

[0006] A first switch is provided on the control circuit, and the first switch is used to turn on and off the control circuit;

[0007] A proximity switch is provided on the control circuit and forms a series connection with the first switch. The proximity switch is used to turn on and off the control circuit;

[0008] When in the working state, the proximity switch monitors the state of the VE rear door. When it monitors that the VE rear door is in the closed state, the proximity switch conducts the control circuit. When it monitors that the VE rear door is in the open state, the proximity switch disconnects the control circuit.

[0009] In a possible implementation manner, the proximity switch is a magnetic proximity switch.

[0010] In a possible implementation manner, the magnetic proximity switch includes a contact end and a magnetic end. When the magnetic end approaches the contact end, the magnetic proximity switch conducts the control circuit. One of the contact end and the magnetic end is used to be arranged on the door panel of the VE rear door, and the other is used to be arranged on the VE wire storage bin.

[0011] In a possible implementation manner, the contact end is used to be arranged on the VE wire storage bin, and the magnetic end is used to be arranged on the door panel of the VE rear door.

[0012] In a possible implementation manner, the number of the first switches and the number of the proximity switches are both one.

[0013] In a possible implementation manner, along the path of the control circuit, the proximity switch is closer to the output end of the control circuit than the first switch.

[0014] In a possible implementation manner, the number of the first switches is one, and the number of the proximity switches is two.

[0015] In a possible implementation manner, along the path of the control circuit, the first switch is located between the two proximity switches.

[0016] In a possible implementation manner, an optocoupler is arranged on the control circuit, and the output end of the optocoupler constitutes the output end of the control circuit.

[0017] In a possible implementation manner, the first switch is a rotary switch.

[0018] According to the cigarette making machine VE rear door interlocking device provided by the embodiments of the present application, under the cooperative action of the first switch and the proximity switch, the first switch and the proximity switch form a series connection. In the working state, the proximity switch is arranged at the position of the VE rear door, and the state of whether the VE rear door is opened or not is monitored through the proximity switch. Only when it is monitored that the VE rear door is in the closed state, the proximity switch conducts the control circuit. At this time, the entire control circuit can be conducted through the first switch. If it is monitored that the VE rear door is in the open state, the proximity switch disconnects the control circuit. At this time, the control circuit cannot be conducted through the first switch, thereby avoiding the VE rear door being squeezed and deformed when the VE wire storage bin is opened and avoiding affecting the normal production of the equipment.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0023] As Figure 2 、 Figure 3 shown, the embodiment of the present application provides a VE rear door interlock device for a cigarette making machine, which is applied to the VE wire storage bin 90 of the ZJ118 type cigarette making machine. When the VE wire storage bin 90 needs to be opened for maintenance, the bottom of the VE wire storage bin 90 is hinged to the equipment. When the VE wire storage bin 90 is opened, the upper part of the VE wire storage bin 90 tilts outward and tilts at a certain angle. Since a VE rear door is also provided outside the VE wire storage bin 90, the bottom of the door panel 91 of the VE rear door is hinged to the outside of the VE wire storage bin 90. When the door panel 91 of the VE rear door is opened, the upper part also swings outward. Opening the door panel 91 of the VE rear door can perform inspections on the internal local structure, etc. In practice, the door panel 91 and the VE wire storage bin 90 can be locked or opened through a handle lock, a knob lock, etc. When the VE wire storage bin 90 is opened, it is operated through a knob switch on the cigarette making machine. When the relevant operator stands at the knob switch, the operator cannot observe the VE rear door on the VE wire storage bin 90, so the opening and closing state of the VE rear door cannot be grasped. When the operator opens the VE wire storage bin 90 by tilting it outward through the knob switch, if the door panel 91 of the VE rear door is in the open state and sags downward at this time, the door panel 91 of the VE rear door will abut against the ground, causing the door panel 91 of the VE rear door to deform, which will in turn affect the subsequent normal production of the equipment. The VE rear door interlock device provided by the present application aims to improve the safety during the opening process of the VE wire storage bin 90, prevent the door panel 91 of the VE rear door from being squeezed and deformed when the VE wire storage bin 90 is opened, and avoid affecting the normal production operation of the equipment.

[0024] In practice, the rotary switch is connected to the control circuit, and the output end of the control circuit is connected to the control module of the cigarette making machine. After the rotary switch conducts the control circuit, the control module of the cigarette making machine receives a signal and then controls the cigarette making machine to enter the maintenance mode. The cigarette making machine stops and opens the VE silk storage bin 90.

[0025] The VE back door interlock device of the cigarette making machine provided by this application includes a control circuit 100, a first switch 201, and a proximity switch 202. The control circuit 100 is provided with an input end and an output end. The output end of the control circuit 100 is connected to the control module of the cigarette making machine to transmit a signal to the control module of the cigarette making machine, so that the cigarette making machine enters the maintenance mode. For example, a voltage signal of 10V - 12V can be input to the input end of the control circuit 100. After the control circuit 100 is conducted, the voltage signal is transmitted to the control module of the cigarette making machine, and then the control module controls the cigarette making machine to enter the maintenance mode. In this mode, the cigarette making machine stops and opens the VE silk storage bin 90.

[0026] The first switch 201 is arranged on the control circuit 100. The first switch 201 is used to conduct or disconnect the control circuit 100. The first switch 201 can be a switch in the form of a knob, a button, or a knife switch, etc. The first switch 201 is preferably a rotary switch. For the installation position of the first switch 201, the first switch 201 is installed on the cigarette making machine.

[0027] The proximity switch 202 is arranged on the control circuit 100. The proximity switch 202 and the first switch 201 are in series. The proximity switch 202 can also realize the on-off of the control circuit 100. The proximity switch 202 can conduct the control circuit 100 or disconnect the control circuit 100. The proximity switch 202 can be installed at the VE back door to monitor the state of the VE back door. When the proximity switch 202 monitors that the VE back door is in the closed state, the proximity switch 202 conducts the control circuit 100. At this time, the on-off operation of the control circuit 100 can be realized through the first switch 201, and the operation of the first switch 201 is effective. When the proximity switch 202 monitors that the VE back door is in the open state, the proximity switch 202 disconnects the control circuit 100. At this time, the entire control circuit 100 is in the disconnected state, and the on-off control of the control circuit 100 cannot be realized through the first switch 201, and the first switch 201 fails.

[0028] In this embodiment, only when the VE back door is in the closed state can the on-off of the control circuit 100 be controlled through the first switch 201, and the opening of the VE silk storage bin 90 can be realized. When the VE back door is in the open state, the control circuit 100 cannot be conducted through the first switch 201, and the VE silk storage bin 90 cannot be opened, thereby effectively avoiding the extrusion deformation of the VE back door panel 91 and ensuring the normal operation of the equipment in the follow-up.

[0029] The proximity switch 202 can be a photoelectric proximity switch 202 or a capacitive proximity switch 202. Preferably, it is a magnetic proximity switch, which has stronger anti-interference ability in the working conditions of a cigarette making machine. The magnetic proximity switch includes a contact end 2021 and a magnetic end 2022. The contact end 2021 is connected to the control circuit 100. When the magnetic end 2022 approaches or contacts the contact end 2021, the contact end 2021 conducts the control circuit 100. When the magnetic end 2022 moves away from the contact end 2021, the contact end 2021 disconnects the control circuit 100. During actual installation, one of the contact end 2021 and the magnetic end 2022 is installed on the door panel 91 of the VE rear door, and the other of the contact end 2021 and the magnetic end 2022 is installed on the VE silk storage bin 90. When the door panel 91 of the VE rear door is closed, the magnetic end 2022 and the contact end 2021 can just come into contact, thereby enabling the monitoring of the opening and closing state of the door panel 91 of the VE rear door. Preferably, the contact end 2021 is installed on the VE silk storage bin 90, and the magnetic end 2022 is installed on the door panel 91 of the VE rear door. Since the contact end 2021 is connected to the control circuit 100, the position of the contact end 2021 can be relatively fixed, and the magnetic end 2022 moves with the door panel 91 on the door panel 91 of the VE rear door, which is beneficial to improving the overall structural stability. When the magnetic end 2022 is installed on the door panel 91 of the VE rear door, the bottom end of the door panel 91 is hinged to the VE silk storage bin 90, and the magnetic end 2022 is arranged at the top position of the door panel 91 of the VE rear door, making the cooperation between the contact end 2021 and the magnetic end 2022 more accurate in responding to the state of the door panel 91.

[0030] In some examples, the number of the first switches 201 is one, and the number of the proximity switches 202 is also one. Along the path of the control line 100, the position of the proximity switch 202 is closer to the output end of the control line 100 than the position of the first switch 201. The first switch 201 and the proximity switch 202 are arranged in sequence along the path of the control line 100, which facilitates subsequent positioning, maintenance and other operations. In another example, the number of the first switches 201 is one, and the number of the proximity switches 202 is two. The two proximity switches 202 are arranged to jointly monitor the state of the VE rear door panel 91, and the monitoring result is more accurate. When two proximity switches 202 are arranged, taking the magnetic proximity switch as an example for illustration. For the installation position, the magnetic proximity switch includes a contact end 2021 and a magnetic end 2022. When facing the door panel 91, the two magnetic ends 2022 are respectively arranged on the left and right sides of the movable top of the door panel 91. When the door panel 91 is closed, the magnetic end 2022 can contact the contact end 2021. In this way, the states of both sides of the door panel 91 are monitored, and the monitoring result is more accurate, ensuring that the door panel 91 is in a completely closed state when the VE wire storage bin is opened. In this example, on the control line 100, along the path of the control line 100, the first switch 201 is located between the two proximity switches 202, and one proximity switch 202, the first switch 201 and the other proximity switch 202 form a series connection, improving the accuracy of monitoring the state of the VE rear door panel 91.

[0031] Preferably, an optocoupler 203 is provided on the control line 100. The output end of the optocoupler 203 is configured as the output end of the control line 100. In this embodiment, one first switch 201 and one proximity switch 202 are provided. Along the path of the control line 100, the first switch 201 is closest to the input end of the control line 100, and the proximity switch 202 is located between the first switch 201 and the optocoupler 203. The first switch 201, the proximity switch 202, and the optocoupler 203 are connected in series. In this embodiment, the control line 100 is used to transmit electrical signals. For example, a 12V voltage signal is connected to the input end of the control line 100. The input end of the optocoupler 203 is connected to the control line 100, and the output end of the optocoupler 203 is connected to the input end of the cigarette machine control module. When both the first switch 201 and the proximity switch 202 conduct the control line 100, the voltage signal is transmitted to the optocoupler 203, causing the light source of the optocoupler 203 to emit light, and then causing the photoreceptor of the optocoupler 203 to generate a more stable electrical signal. In this way, even if the electrical signal on the control line 100 fluctuates, the electrical signal transmitted from the optocoupler 203 to the cigarette machine control module can still remain stable, which is beneficial to improving the stability of signal transmission and avoiding causing a fluctuating impact on the control module of the cigarette machine. It should be noted that the signal fluctuation on the control line 100 needs to be controlled within the light source triggering range of the optocoupler 203, and this range is the fluctuation range of the control line 100, so that the light source of the optocoupler 203 can be triggered to emit light, and then the photoreceptor of the optocoupler 203 can be triggered.
