[0031] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] Figure 1 It is a schematic diagram showing the structure of a smoke blockage detection device for a horizontal conveyor belt of a bagging machine according to some embodiments of the present disclosure.

[0033] like Figure 1 As shown, the smoke blockage detection device includes: a controller 110, a digital input module 120, a photoelectric detection switch (also called a photoelectric detection switch) 130 and a human-machine interface (HMI) device 140. The photoelectric detection switch 130 is installed above the horizontal conveyor belt. Here, the photoelectric detection switch is installed above the horizontal conveyor belt, which means that the photoelectric detection switch is installed above the plane where the horizontal conveyor belt is located, as long as it can detect the cigarette strips on the horizontal conveyor belt. The controller 110 is electrically connected to the digital input module 120 and the human-machine interface device 140 respectively. The photoelectric detection switch 130 is electrically connected to the digital input module 120.

[0034] The photoelectric detection switch 130 is used to send a cigarette rod presence signal to the digital quantity input module 120 when detecting the presence of cigarette rods on the horizontal conveyor belt of the packing machine. The cigarette rod presence signal is a switch signal. For example, the photoelectric detection switch 130 is electrically connected to the digital quantity input module 120 through a shielded cable. For example, the photoelectric detection switch is a diffuse reflection photoelectric switch. The photoelectric detection switch can detect in real time whether there are cigarette rods on the horizontal conveyor belt of the packing machine, and send a cigarette rod presence signal to the digital quantity input module.

[0035] The digital quantity input module 120 is used to collect the cigarette rod presence signal of the photoelectric detection switch, convert the cigarette rod presence signal into a digital quantity signal recognizable by the controller, and send the digital quantity signal to the controller. For example, the digital quantity input module can be a digital quantity input module of a packing machine. For example, the digital quantity input module 120 is electrically connected to the controller 110 via a backplane bus.

[0036] The controller 110 is used to receive the digital quantity signal (as the cigarette rod presence signal) transmitted by the digital quantity input module, and perform a logical judgment to determine whether the cigarette rods on the horizontal conveyor belt of the packing machine are blocked. Specifically, the controller 110 is used to calculate the cigarette rod presence time according to the digital quantity signal as the cigarette rod presence signal, and when the cigarette rod presence time is greater than the cigarette blocking set time (as the time threshold), it is determined that the cigarette blocking phenomenon occurs on the horizontal conveyor belt, and the packing machine is controlled to stop, and an alarm message is sent to the human-machine interface device. For example, the logic control program module can be developed in the controller 110 using languages ​​such as SIMATIC Step7.

[0037] For example, the controller 110 is a programmable logic controller (PLC for short). The PLC may be a control center PLC (for example, a control center PLC of a packing machine).

[0038] For another example, the controller can be implemented by a control circuit. For example, the control circuit includes a timer and a comparator, wherein the timer is electrically connected to the comparator and the digital quantity input module respectively, and the comparator is electrically connected to the human-machine interface device and the control center PLC of the packing machine respectively. The timer is used to time the digital quantity signal as the cigarette rod existence signal to obtain the cigarette rod existence time, and transmit the cigarette rod existence time to the comparator; the comparator is used to receive the cigarette rod existence time and the cigarette blocking setting time, compare the cigarette rod existence time and the cigarette blocking setting time, and output a control signal to control the packing machine to stop and control the human-machine interface device to display an alarm message when the cigarette rod existence time is greater than the cigarette blocking setting time.

[0039] The human-machine interface device (i.e., HMI system) 140 is used to receive the input of the smoke blocking setting time, transmit the smoke blocking setting time to the controller, and receive alarm information from the controller to alarm. For example, the human-machine interface device 140 is embedded with a horizontal conveyor belt smoke blocking monitoring screen, so that the human-machine interface device can display the cigarette rod presence signal and cigarette rod blockage alarm information transmitted by the controller in real time, and the smoke blocking setting time for judging whether the horizontal conveyor belt is blocked by cigarette rods can be freely set on the horizontal conveyor belt smoke blocking monitoring screen. For example, the human-machine interface device is a packing machine HMI system. For example, the human-machine interface device includes a touch display screen. For example, the human-machine interface device and the controller are connected through TCP / IP (Transmission Control Protocol / Internet Protocol). This enables rapid exchange of information.

[0040] In some embodiments, the smoke blocking setting time may range from 2 seconds to 3 seconds. For example, the smoke blocking setting time may be 2.5 seconds. Of course, those skilled in the art will appreciate that the above-mentioned smoke blocking setting time range is only exemplary, and the scope of the present disclosure is not limited to the specific value of the smoke blocking setting time, and the smoke blocking setting time may be set according to actual needs.

[0041] So far, a smoke blockage detection device for a horizontal conveyor belt of a packing machine according to some embodiments of the present disclosure is provided. The smoke blockage detection device includes: a controller, a digital input module, a photoelectric detection switch, and a human-machine interface device, wherein the photoelectric detection switch is installed above the horizontal conveyor belt, the controller is electrically connected to the digital input module and the human-machine interface device, respectively, and the photoelectric detection switch is electrically connected to the digital input module. The smoke blockage detection device can realize automatic detection of the cigarette rod blockage phenomenon on the horizontal conveyor belt of the packing machine, thereby timely discovering the cigarette rod blockage phenomenon.

[0042] Figure 2 is a side schematic diagram showing the horizontal conveyor belt and vertical conveying part of the bag arrangement machine according to some embodiments of the present disclosure.

[0043] like Figure 2 As shown, the packing machine includes a horizontal conveyor belt 220. The packing machine also includes one or more vertical conveying sections 230. For example, Figure 2 9 vertical conveying sections 231 to 239 are shown in FIG. The one or more vertical conveying sections 230 are arranged in sequence along the transport direction 210 of the horizontal conveyor belt 220 of the packing machine. The transport direction is the direction from the first position 211 to the second position 212. Here, compared with the first position, the second position is closer to the box filling machine (not shown in the figure). The one or more vertical conveying sections 230 are located between the first position 211 and the second position 212. For example, Figure 2 As shown, according to the direction from the first position 211 to the second position 212, multiple vertical conveying sections 231 to 239 are respectively called the first vertical conveying section 231, the second vertical conveying section 232, the third vertical conveying section 233, the fourth vertical conveying section 234, the fifth vertical conveying section 235, the sixth vertical conveying section 236, the seventh vertical conveying section 237, the eighth vertical conveying section 238 and the ninth vertical conveying section 239.

[0044] In some embodiments, in addition to the controller, the digital input module, the photoelectric detection switch and the human-machine interface device, the smoke blocking detection device may also include a mounting bracket. The mounting bracket is mounted on the two side columns of at least one of the one or more vertical conveying sections. The photoelectric detection switch is arranged on the mounting bracket. In this way, the purpose of mounting the photoelectric detection switch above the horizontal conveyor belt by using the mounting bracket is achieved.

[0045] For example, the smoke blocking detection device can use a mounting bracket, which is installed on two side columns of a vertical conveying part, and the photoelectric detection switch is set on the mounting bracket.

[0046] For another example, the smoke blockage detection device may use a plurality of mounting brackets, each mounting bracket being mounted on two side columns of a corresponding vertical conveying portion, and a plurality of photoelectric detection switches being mounted one-to-one on the plurality of mounting brackets.

[0047] Figure 3 Schematic diagram showing the installation position of a photoelectric detection switch of a smoke blockage detection device according to some embodiments of the present disclosure.

[0048] Figure 3 The vertical conveying part has two side columns 241 and 242 and a plurality of tobacco rods 310. Here, Figure 3 The columns 241 and 242 shown in the figure are the columns of the front row of the bagging machine, that is, the columns on both sides of the first vertical conveying part 231, and the columns on both sides of the other vertical conveying parts 231 are in the Figure 3 Not shown.

[0049] As mentioned above, the smoke blockage detection device may also include a mounting bracket 150. The mounting bracket 150 is mounted on the two side columns 241 and 242 of the vertical conveying section closest to the first position in the one or more vertical conveying sections. That is, the mounting bracket is mounted on the two side columns at the front end of the vertical conveying section of the packing machine. In other words, the mounting bracket is mounted on the first two side columns of the vertical conveying section of the packing machine. In this way, after the photoelectric detection switch is mounted on the mounting bracket, the photoelectric detection switch can detect whether the tobacco rods transported by the multi-channel vertical conveying sections are blocked.

[0050] For example, Figure 3 As shown, the mounting bracket 150 is a rectangular iron block, and the mounting bracket 150 is parallel to the horizontal conveyor belt 220 of the bag arranging machine. Of course, those skilled in the art will understand that the shape and material of the mounting bracket here are only exemplary, and the scope of the present disclosure is not limited to the specific shape and material of the mounting bracket.

[0051] For example, a threaded hole is provided at the center of the mounting bracket 150, and the photoelectric detection switch 130 is fixed at the center of the mounting bracket by bolts, so that the photoelectric detection switch can be fixed conveniently.

[0052] The photoelectric detection switch has an integrated sensitivity adjustment function, which can detect the presence of cigarette rods on the horizontal conveyor belt of the packing machine in real time and send a cigarette rod presence signal to the digital quantity module.

[0053] In the above embodiment, the mounting bracket is installed on the two side columns at the front end of the vertical conveying part of the packing machine, and the photoelectric detection switch is fixed to the center position of the mounting bracket by bolts. In this way, only one photoelectric detection switch is needed to detect whether the tobacco rods transported by multiple vertical conveying parts are blocked, thereby reducing costs.

[0054] Thus, the present disclosure provides a smoke blockage detection device for the horizontal conveyor belt of a packing machine. When the horizontal conveyor belt is blocked by cigarette rods, the smoke blockage detection device can quickly control the packing machine to stop, thereby avoiding a large number of cigarette rods from being squeezed and damaged as much as possible, and the sensitivity of the photoelectric detection switch can be freely adjusted, and the smoke blockage judgment time can be freely set, which is convenient for operation and maintenance.

[0055] Compared with the related art, the smoke blocking detection device disclosed in the present invention has the following beneficial effects:

[0056] First, the photoelectric detection switch used in the embodiment of the present disclosure adopts semiconductor device electronic switch and electronic digital detection technology, has high precision, does not involve mechanical action, and has a fast response speed; the detection distance is between a few centimeters and tens of meters, and can be freely adjusted according to actual conditions; light-emitting diodes are used as light sources, and the output is controlled in a non-contact manner, with a long service life.

[0057] Second, when the horizontal conveyor belt of the bale placing machine is blocked by cigarette smoke, the controller can control the bale placing machine to stop quickly to avoid a large number of cigarette rods being squeezed and damaged due to untimely manual shutdown.

[0058] Third, a smoke blockage alarm screen for the horizontal conveyor belt of the bale sorting machine is embedded in the human-machine interface device of the disclosed embodiment, which can display the smoke blockage alarm information in real time, and the cigarette blockage judgment time (i.e., the smoke blockage setting time) for the horizontal conveyor belt of the bale sorting machine can be freely set on the human-machine interface device, which is convenient for operation and maintenance.

[0059] Fourth, the controller can be the PLC of the control center of the packaging machine, the digital input module can be the digital input module of the packaging machine, and the human-machine interface device can be the HMI system of the packaging machine. There is no need for an additional control center PLC, digital input module and HMI system, which is simple to transform and saves a lot of cost.

[0060] Figure 4FIG. 1 is a flow chart showing a control method for a smoke blocking detection device according to some embodiments of the present disclosure. Figure 4 As shown, the control method includes steps S402 to S418.

[0061] In step S402, the device is powered on and started.

[0062] In step S404, the photoelectric detection switch detects a tobacco rod presence signal.

[0063] In step S406, the controller reads the tobacco rod presence signal.

[0064] In step S408, the existence time of the cigarette rod is calculated, that is, the existence time of the cigarette rod at the current position of the cigarette rod on the horizontal conveyor belt is determined according to the duration of the cigarette rod existence signal.

[0065] In step S410, the existence time of the cigarette rod is transmitted to the human-machine interface device to display the existence time of the cigarette rod in real time.

[0066] In step S412, it is determined whether the existence time of the cigarette rod is greater than the set smoke blocking time. If yes, the process proceeds to step S416; otherwise, the process proceeds to step S414.

[0067] In step S414, the device enables output normally.

[0068] In step S416, a fault alarm is issued.

[0069] In step S418, the device is shut down.

[0070] So far, a control method for a smoke blocking detection device according to some embodiments of the present disclosure is provided. The control method can realize automatic detection of the blockage of cigarette rods on the horizontal conveyor belt of the packing machine, so as to timely discover the blockage of cigarette rods. Therefore, the control method plays a good preventive effect on the situation where horizontal cigarettes enter the horizontal conveyor belt of the packing machine, causing blockage of cigarette rods and thus causing a large number of cigarette rods to be damaged.

[0071] In the smoke blockage detection device of the embodiment of the present disclosure, the smoke blockage detection device uses a photoelectric detection switch. When a cigarette rod appears on the horizontal conveyor belt of the packing machine, the photoelectric detection switch detects the presence of the cigarette rod. If the existence time of the cigarette rod exceeds the set smoke blockage time, it is determined that the horizontal conveyor belt of the packing machine is blocked by smoke. According to the control method, a smoke blockage signal is output to the PLC of the packing machine, an alarm message is generated, and the machine is controlled to stop. It can only be reset and restarted after the blocked cigarette rod is removed. In view of the situation where horizontal smoke enters the horizontal conveyor belt of the packing machine, causing the cigarette rod to be blocked and then causing a large amount of damage to the cigarette rod, the smoke blockage detection device and its control method of the embodiment of the present disclosure have a good preventive effect.
