Description

Technical Field

[0001] This utility model relates to the field of packaging machine control technology, and in particular to a continuous strip detection device for packaging machines. Background Technology

[0002] In the production and transportation of cigarette cartons, the elevator is a crucial step, used to transport the cigarette cartons from the main machine to the sealing machine for packing. However, in practice, the elevator sometimes stops suddenly for various reasons. While the main machine is still running, this can cause the cigarette cartons to be crushed and fall during transport, resulting in quality problems, economic losses, and wasted manpower in handling the situation. Traditional solutions typically rely on operators monitoring the elevator's operating status and manually stopping it when an anomaly is detected. This method suffers from a reaction delay; operators may not immediately notice the elevator stopping, leading to a large number of cigarette cartons falling and resulting in waste.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] Figure 1 This is a circuit connection diagram of a strip detection device for a packaging machine according to an embodiment of the present invention. Figure 2 This is a partial structural diagram of a packaging machine according to an embodiment of the present utility model. Figure 3 This is a schematic diagram of the module connection of a continuous strip detection device for a packaging machine according to an embodiment of the present utility model, combined with... Figure 1 , Figure 2 and Figure 3 As shown, the continuous strip detection device of the packaging machine includes:

[0034] Photoelectric switch 1, contactor 2, and control unit 3;

[0035] Photoelectric switch 1 is installed on the conveying unit 40 of the transparent packaging machine 4; the continuous signal output terminal of photoelectric switch 1 is communicatively connected to the continuous signal receiving terminal I0.0 of the control unit 3;

[0036] The stop signal output terminal Q0.0 of control unit 3 is communicatively connected to the stop signal receiving terminal of contactor 2;

[0037] The stop control terminal of contactor 2 is communicatively connected to transparent packaging machine 4.

[0038] The photoelectric switch 1 is used to emit and receive the reflected light beam to detect whether a chain of cigarettes has formed. This chain can occur when cigarettes accumulate on the packaging machine 4, causing them to pile up. When a chain-forming fault occurs, the photoelectric switch 1 on the transparent packaging machine 4 continuously receives the reflected light beam and inputs the chain-forming signal from its output terminal to the chain-forming signal receiving terminal I0.0 of the control unit 3. When a chain-forming fault occurs, the photoelectric switch 1 continuously detects the reflected light beam and continuously inputs the chain-forming signal to the control unit 3.

[0039] When the elevator stops, the continuous operation of the packaging machine 4 can lead to a chain failure. Contactor 2 can be used to control the operation and shutdown of the packaging machine 4. The stop signal output terminal Q0.0 of the control unit 3 is communicatively connected to the stop signal receiving terminal of the contactor 2, and the stop control terminal of the contactor 2 is communicatively connected to the transparent packaging machine 4. The control unit 3 can output a stop signal to the contactor 2, causing the contactor 2 to disconnect, thereby controlling the transparent packaging machine 4 to stop operating.

[0040] For example, when the elevator stops, the cigarette packs will continue to be pushed onto the elevator via the conveying unit 40 of the transparent packaging machine 4. Since the elevator stops, a chain will form at the connection between the packaging machine 4 and the elevator. At this time, the photoelectric switch 1 is continuously triggered, and the chain signal is output to the chain signal receiving terminal I0.0 of the control unit 3 via the chain signal output terminal. The stop signal output terminal Q0.0 of the control unit 3 outputs a stop signal to the contactor 2. The stop control terminal of the contactor 2 is disconnected from the transparent packaging machine 4, thereby causing the transparent packaging machine 4 to stop.

[0041] Understandably, in the existing technology, the transparent packaging machine 4 is not yet linked to the start and stop of the elevator, lacking a mechanism for automatically detecting the elevator's status and unable to react immediately when the elevator stops. However, the technical solution of this utility model embodiment, through photoelectric switch 1, control unit 3, and contactor 2, achieves automatic detection of the continuous strips and shutdown control of the packaging machine 4, reducing reliance on operator monitoring and ensuring an immediate response when the elevator stops, avoiding delays caused by human factors.

[0042] The technical solution of this utility model embodiment, by setting up a continuous strip detection device on the basis of the existing packaging machine 4 and elevator structure, realizes automatic detection of continuous strip faults and control of the shutdown of packaging machine 4 through photoelectric switch 1, contactor 2 and control unit 3, ensuring that packaging machine 4 can stop in conjunction with the elevator when it stops, avoiding unnecessary waste of resources. The technical solution of this utility model embodiment reduces human dependence, avoids the delay problem of manual monitoring, and improves the automation level of the equipment.

[0043] Optional, continue to refer to Figure 1 , Figure 2 and Figure 3 As shown, the continuous strip detection device also includes a relay 5;

[0044] Relay 5 is connected in series between the stop signal output terminal Q0.0 and the stop signal receiving terminal.

[0045] Among them, relay 5 can be used to control the working state of contactor 2. Relay 5 is connected in series between the stop signal output terminal Q0.0 and the stop signal receiving terminal. When the coil of relay 5 is energized, it can disconnect contactor 2, thereby disconnecting the stop control terminal of contactor 2 from the transparent packaging machine 4, causing the transparent packaging machine 4 to stop.

[0046] For example, such as Figure 1 As shown, the continuous signal output terminal of photoelectric switch 1 is connected to the continuous signal receiving terminal I0.0 of control unit 3, and the stop signal output terminal Q0.0 is connected to one end of relay 5, and the other end of relay 5 is connected to contactor 2. When the equipment elevator stops, the cigarette sticks will continue to be pushed to the elevator to form a continuous chain. At this time, photoelectric switch 1 is continuously triggered and sends a signal to I0.0 of control unit 3. Control unit 3 outputs stop signal Q0.0 to energize the coil of relay 5, disconnect contactor 2, and stop the conveying unit 40 of packaging machine 4, thereby preventing the continuous accumulation of cigarette sticks.

[0047] The technical solution of this utility model embodiment utilizes the linkage control of control unit 3, relay 5 and contactor 2 to control the operation of transparent packaging machine 4. As a result, when photoelectric switch 1 is continuously triggered by cigarette stick, control unit 3 sends a stop signal to stop transparent packaging machine 4. The cigarette stick will not be pushed to the elevator, and the cigarette stick will not fall due to continued pushing, thus protecting product quality, reducing cigarette stick damage, and lowering production costs.

[0048] Optional, continue to refer to Figure 1 , Figure 2 and Figure 3 As shown, photoelectric switch 1 is installed on the side of conveying unit 40 near the hoist;

[0049] The detection light of photoelectric switch 1 is incident on the cigarette pack on the conveying unit 40.

[0050] When the elevator stops and the transparent packaging machine 4 continues to run, the cigarette packs are prone to breakage at the connection between the elevator and the conveying unit 40. Therefore, a photoelectric switch 1 is set on the side of the conveying unit 40 near the elevator so that the photoelectric switch 1 can detect the breakage more promptly and accurately. When a breakage occurs, the detection light of the photoelectric switch 1 can accurately enter the cigarette pack of the conveying unit 40, thereby ensuring the detection accuracy of the photoelectric switch 1.

[0051] The technical solution of this utility model embodiment is to place the photoelectric switch 1 on the side of the conveying unit 40 close to the elevator. The detection light of the photoelectric switch 1 is incident on the cigarette strips on the conveying unit 40, thereby enabling the photoelectric switch 1 to detect the cigarette strip failure more timely and accurately. Through automated control, the dependence on operator monitoring is reduced, ensuring that it can react immediately when the elevator stops, avoiding delays caused by human factors, and improving the accuracy of cigarette strip detection.

[0052] Optionally, control unit 3 includes a timer; (not shown in the figure)

[0053] The timer includes a continuous signal receiver I0.0 and a stop signal output Q0.0;

[0054] The timer is used to receive the chain signal and count the trigger time of the chain signal. When the trigger time reaches the preset time, the stop signal is output through the stop signal output terminal Q0.0.

[0055] The control unit 3 is equipped with a timer that can detect the duration of continuous triggering of photoelectric switch 1. To ensure the accuracy of the chain fault judgment, a preset time is set, which represents the shortest duration of photoelectric switch 1 corresponding to the chain fault. After the chain signal receiving terminal I0.0 receives the chain signal, the timer starts to count the continuous triggering time of the chain signal. When the triggering time reaches the preset time, it indicates that a chain fault of cigarettes has occurred, and the stop signal output terminal Q0.0 outputs a stop signal, thereby controlling the transparent packaging machine 4 to stop.

[0056] For example, the preset time is set to 3 seconds. When the trigger time of the continuous signal reaches 3 seconds, the control unit 3 determines that a continuous fault has occurred.

[0057] In some embodiments, the timer is also used to recalculate the trigger time of the chain signal if the trigger time has not reached a preset time. For example, if the trigger time of the chain signal has not reached 3 seconds, the control unit 3 determines that no chain fault has occurred, and then recalculates the continuous trigger time when a chain signal is subsequently received.

[0058] The technical solution of this utility model embodiment sets a timer to count the continuous triggering time of the cigarette stick signal, and controls the transparent packaging machine 4 to stop when the triggering time reaches the preset time. This ensures the accuracy of judging the cigarette stick fault, improves the automation level of the cigarette stick detection device, reduces the dependence on manual operation, and avoids the cigarette stick falling due to human negligence.

[0059] Optional, continue to refer to Figure 1 , Figure 2 and Figure 3 As shown, the continuous strip detection device also includes a buzzer 6;

[0060] The stop signal output terminal Q0.0 is also connected to the trigger terminal of buzzer 6.

[0061] The buzzer 6 is an electronic component that converts electrical signals into sound, used to emit alarm, prompt, or signal sounds. The stop signal output terminal Q0.0 is also communicatively connected to the trigger terminal of the buzzer 6, so that the buzzer 6 can be activated simultaneously after the stop signal is output to provide a voice prompt, thereby enabling the staff to know the working status of the transparent packaging machine 4 in a timely manner.

[0062] The technical solution of this utility model embodiment is to set up a buzzer 6 and connect the stop signal output terminal Q0.0 to the trigger terminal of the buzzer 6. At the same time as the stop signal is output, the buzzer 6 is triggered to start and emit an alarm sound, so as to promptly remind the operator to pay attention. This ensures the timely reminder and rapid response of the continuous strip detection device, and ensures that the operator can discover the problem in time and take measures to avoid the fault from escalating further.

[0063] Optional, continue to refer to Figure 1 , Figure 2 and Figure 3 As shown, the stop signal output terminal Q0.0 is also connected to the main control board 7 of the transparent packaging machine 4;

[0064] The main unit control board 7 is used to display shutdown information.

[0065] The main control board 7 serves as the central control system for the packaging machine 4, monitoring and controlling the production process, electromechanical equipment, and process equipment. Connecting the stop signal output terminal Q0.0 to the main control board 7 of the transparent packaging machine 4 allows the main control board 7 to display stop information simultaneously with the output of the stop signal. This helps operators quickly pinpoint the problem type and location, shortening processing time and improving equipment operating efficiency.

[0066] Specifically, when the equipment elevator stops, the cigarette sticks will continue to be pushed to the elevator to form a continuous chain. At this time, the photoelectric switch 1 is continuously triggered and sends a signal to the control unit 3. When the trigger time of the continuous chain signal reaches the preset time, the control unit 3 outputs a stop signal to energize the coil of the relay 5, disconnect the contactor 2 to stop the conveyor belt, trigger the buzzer 6 to alarm, and send a stop signal to the main control board 7, so that the transparent packaging machine 4 stops and the stop information is displayed on the main control board 7 to help the operator quickly locate the problem.

[0067] The technical solution of this utility model embodiment connects the shutdown signal output terminal Q0.0 with the main control board 7 of the transparent packaging machine 4, so that the control unit 3 can control the transparent packaging machine 4 to stop while displaying detailed shutdown information on the main control board 7. This allows operators to quickly understand the fault type, locate the problem, improve fault handling efficiency, shorten equipment downtime, and ensure production efficiency.

[0068] Optionally, the continuous strip detection device may also include a power supply unit;

[0069] The power supply unit is electrically connected to photoelectric switch 1, control unit 3 and contactor 2 respectively.

[0070] The power supply unit can be used to supply power to the photoelectric switch 1, the control unit 3, and the contactor 2 respectively. In some embodiments, the voltage of the power supply unit is 24V to ensure the normal operation of the photoelectric switch 1, the control unit 3, and the contactor 2.

[0071] Optional, continue to refer to Figure 3 As shown, the transparent packaging machine 4 includes a working status indicator light 8;

[0072] The stop signal output terminal Q0.0 is also connected to the working status indicator light.

[0073] The working status indicator light can display different working states of the packaging machine 4 by emitting different colored lights. The stop signal output terminal Q0.0 is also connected to the working status indicator light. After the stop signal is output, it can trigger the working status indicator light to change, so that the staff can know the working status of the transparent packaging machine 4 in a timely manner.

[0074] The technical solution of this utility model embodiment also communicates with the working status indicator light through the stop signal output terminal Q0.0. At the same time as the stop signal is output, the light of the working status indicator light is triggered to change, so as to promptly remind the operator to pay attention. This ensures that the continuous strip detection device can promptly remind and respond quickly, so that the operator can discover the problem in time and take measures to avoid the fault from escalating further.

[0075] It should be understood that the various forms of the process shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this utility model can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this utility model can be achieved, and this is not limited herein.

[0076] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors.
