Description

Technical Field

[0001] This utility model relates to the field of tobacco equipment control, and in particular to a detection device and a tray loading machine for a tray loading system. Background Technology

[0002] Routine equipment maintenance is a fundamental requirement for ensuring normal production in the workshop. Currently, the relay contacts connected to the blocking magnet in the rotary table machine are prone to poor contact. In actual production, the relay often closes but fails to transmit the signal further to the blocking magnet, leading to cigarette blockage in the cigarette storage compartment. Furthermore, the location most likely to cause blockage is at a high point in the compartment, and the equipment does not stop immediately, causing the number of cigarettes in the compartment to increase, resulting in wrinkled and broken cigarettes, thus affecting the overall yield rate. Utility Model Content

[0003] This utility model provides a tray loading system detection device and tray loading machine. By adding an inspection unit to the tray loading system detection device, the movement position of the piston is detected, thereby realizing the detection of cigarette obstruction and improving the accuracy of the detection.

[0004] In a first aspect, the present invention provides a tray loading system detection device, including a circuit switch, a blocking magnet, an inspection unit, a bracket, and a controller;

[0005] The blocking magnet includes a housing and a piston. The housing includes a first bottom surface, a second bottom surface, and a side surface. The first bottom surface and the second bottom surface extend along a first direction and are arranged along a second direction. The side surface connects the first bottom surface and the second bottom surface. The first bottom surface includes a first hollow unit, and the second bottom surface includes a second hollow unit. The piston moves along the second direction to the first hollow unit or to the second hollow unit. The first direction and the second direction intersect. The first bottom surface is located on the side of the second bottom surface closer to the cigarette blocking plate.

[0006] The bracket includes a first end and a second end. The first end is connected to the side of the housing, and the second end is connected to the inspection unit. The inspection unit is located on the side of the second bottom surface away from the first bottom surface.

[0007] The circuit switch includes an energized relay and a delay relay. The energized relay includes a first input terminal and a first output terminal, and the delay relay includes a second input terminal and a second output terminal.

[0008] The blocking magnet includes a third input terminal, the inspection unit includes a fourth input terminal and a third output terminal, and the controller includes a fourth output terminal and a fifth input terminal;

[0009] The fourth output terminal is connected to the first input terminal and the second input terminal, the first output terminal is connected to the third input terminal, the second output terminal is connected to the fourth input terminal, and the third output terminal is connected to the fifth input terminal.

[0010] Optionally, the inspection unit includes an oscillator proximity switch.

[0011] Optionally, the tray loading system detection device further includes an optocoupler, which includes a first connection end and a second connection end. The first connection end is connected to the third output end, and the second connection end is connected to the fifth input end.

[0012] Optionally, the oscillator proximity switch includes an NPN normally closed proximity switch.

[0013] Optionally, the inspection unit includes an image acquisition unit.

[0014] Optionally, the image acquisition unit includes a laser image acquisition unit.

[0015] Optionally, the tray loading system detection device further includes a photoelectric switch, which is located on the side of the cigarette blocking plate away from the blocking magnet;

[0016] The photoelectric switch includes a fifth output terminal, and the controller also includes a sixth input terminal, with the fifth output terminal and the sixth input terminal connected together.

[0017] Optionally, the tray loading system detection device further includes a human-machine interaction unit, which is connected to the controller.

[0018] Optionally, the tray loading system detection device further includes an alarm unit, which is connected to the controller or the human-machine interface unit.

[0019] Secondly, embodiments of the present invention provide a tray loading machine, including the tray loading system detection device described in any one of the first aspects.

[0020] This utility model embodiment provides a tray loading system detection device. The circuit switch in the tray loading system detection device includes an energized relay and a delay relay. One end of the energized relay is connected to a controller, and the other end is connected to a blocking magnet. When the controller controls the contacts of the energized relay to close, the energized relay can control the piston in the blocking magnet to move from the first hollow unit to the second hollow unit, thereby opening the cigarette blocking plate and ensuring the normal drop of cigarettes. However, there is a possibility of abnormal contact of the energized relay. Even if the contacts of the energized relay are engaged, but the piston in the blocking magnet is not controlled to move from the first hollow unit to the second hollow unit, the cigarette blocking plate will still be blocked by the piston and cannot be opened, resulting in cigarette accumulation. Furthermore, the tray loading system detection device also includes an inspection unit located on the side of the second bottom surface away from the first bottom surface. Thus, the inspection unit can detect whether the piston has moved to the second hollow unit and can transmit the corresponding signal to the controller to judge the movement of the piston, thereby determining whether there is a blockage of cigarettes. By adding an inspection unit, the movement of the piston can be judged, and the accuracy of the detection device in the loading system can be improved by combining the judgment of the piston movement.

[0033] Figure 1 This is a schematic diagram of the structure of a tray loading system detection device provided in an embodiment of this utility model. Figure 2 This is a schematic diagram of another tray loading system detection device provided in this embodiment of the utility model. Figure 3 This is a front view of the structure of a tray loading system detection device provided in an embodiment of this utility model. Figure 4 This is a side view of the structure of a tray loading system detection device provided in an embodiment of this utility model, with reference to... Figures 1 to 4As shown, this embodiment of the present invention provides a tray loading system detection device 10, which includes a circuit switch 100, a blocking magnet 200, an inspection unit 400, a bracket 300, and a controller 500. The blocking magnet 200 includes a housing 210 and a piston 220. The housing 210 includes a first bottom surface 211, a second bottom surface 212, and a side surface 213. The first bottom surface 211 and the second bottom surface 212 extend along a first direction X1, and the first bottom surface 211 and the second bottom surface 212 extend along a second direction X1. The components are arranged in an X2 direction, with side 213 connecting the first bottom surface 211 and the second bottom surface 212; the first bottom surface 211 includes a first hollow unit 211a, and the second bottom surface 212 includes a second hollow unit 212a. The piston 220 moves along the second direction X2 to the first hollow unit 211a or to the second hollow unit 212a, and the first direction X1 and the second direction X2 intersect; the first bottom surface 211 is located on the side of the second bottom surface 212 near the cigarette holder 20; the support 300 includes a first end 310 and a second end 312a. Two ends 320, the first end 310 is connected to the side 213 of the housing 210, and the second end 320 is connected to the inspection unit 400, which is located on the side of the second bottom surface 212 away from the first bottom surface 211; the circuit switch 100 includes an energized relay 110 and a delay relay 120, the energized relay 110 includes a first input terminal 110a and a first output terminal 110b, and the delay relay 120 includes a second input terminal 120a and a second output terminal 120b; the blocking magnet 200 includes The third input terminal 200a, the inspection unit 400 includes a fourth input terminal 400a and a third output terminal 400b, and the controller 500 includes a fourth output terminal 500a and a fifth input terminal 500b; wherein, the fourth output terminal 500a is connected to the first input terminal 110a and the second input terminal 110a respectively, the first output terminal 110b is connected to the third input terminal 200a, the second output terminal 120b is connected to the fourth input terminal 400a, and the third output terminal 400b is connected to the fifth input terminal 500b.

[0034] The tray loading system detection device 10 includes a blocking magnet 200, which contains a piston 220. Figure 1 As shown, when piston 220 moves upward, it can press against cigarette baffle 20, thus preventing the cigarette (not specifically shown in the figure) from falling further; Reference Figure 2 As shown, when the piston 220 moves downward, it separates from the cigarette baffle 20, the cigarette baffle 20 opens, and the cigarette can fall normally. In other words, when the piston 220 moves downward, the cigarette baffle 20 is open, which is equivalent to the tray loading system being open; when the piston 220 is pressed against the cigarette baffle 20, it is equivalent to the tray loading system not being open.

[0035] For details, please refer to Figures 1 to 4As shown, the blocking magnet 200 includes a housing 210 and a piston 220. The housing 210 includes a first bottom surface 211, a second bottom surface 212, and a side surface 213. The first bottom surface 211 and the second bottom surface 212 are two opposing surfaces, and are arranged along a second direction X2. The side surface 213 connects the first bottom surface 211 and the second bottom surface 212. Further, the first bottom surface 211 includes a first hollow unit 211a, and the second bottom surface 212 includes a second hollow unit 212a. The piston 220 in the blocking magnet 200 extends along the second direction X2. The piston 220 can extend to the first hollow unit 211a, such as... Figure 1 As shown; the piston 220 can also extend to the second hollow unit 212a, as... Figure 2 As shown.

[0036] Furthermore, the first bottom surface 211 is located on the side of the second bottom surface 212 near the cigarette holder 20, for reference. Figure 1 As shown, piston 220 can extend to the first hollow unit 211a, and piston 220 presses against cigarette blocking plate 20, so that the cigarette will not fall through cigarette blocking plate 20; Reference Figure 2 As shown, the piston 220 can also extend to the second hollow unit 212a. The piston 220 does not press against the cigarette blocking plate 20, so the cigarette can fall through the cigarette blocking plate 20.

[0037] Further reference Figure 1 and Figure 2 As shown, the tray loading system detection device 10 also includes a circuit switch 100 and a controller 500. The circuit switch 100 includes an energized relay 110, and the controller 500 can be a programmable logic controller (PLC). The energized relay 110 includes a first input terminal 110a and a first output terminal 110b, the blocking magnet 200 includes a third input terminal 200a, and the controller 500 includes a fourth output terminal 500a. Figure 1 and Figure 2 As shown, the first input terminal 110a and the fourth output terminal 500a are connected, and the controller 500 can control the contacts of the energized relay 110 to close. Further, the first output terminal 110b is connected to the third input terminal 200a. When the contacts of the energized relay 110 are closed, the blocking magnet 200 is energized, moving the piston 220 from the first hollow unit 211a to the second hollow unit 212a. This can be understood as the blocking magnet 200 being opened, allowing the oscillator (not specifically shown in the figure) within the blocking magnet 200 to oscillate, thus facilitating the dropping of the cigarette. Figure 1 Convert to Figure 2In its normal operating state, the cigarette falls normally, and the cigarette blocking plate 20 no longer blocks the cigarette. However, in the existing technology, as the contacts of the energized relay 110 continuously engage and disengage, combined with its operating environment, the contacts of the energized relay 110 are prone to oxidation. This can lead to a situation where the contacts of the energized relay 110 are engaged, but the blocking magnet 200 is not energized. Consequently, the piston 220 may remain at the first hollow unit 211a and cannot move to the second hollow unit 212a, which is equivalent to the blocking magnet 200 not opening, causing cigarette blockage, affecting the shape and quality of the cigarette, and thus the overall yield rate of cigarettes.

[0038] Further reference Figures 1 to 4 As shown, the tray loading system detection device 10 also includes an inspection unit 400 and a bracket 300. The bracket 300 includes a first end 310 and a second end 320. The first end 310 is connected to the side 213 of the housing 210, and the second end 320 is connected to the inspection unit 400. The bracket 300 is mechanically connected to both the housing 210 and the inspection unit 400. The specific mechanical connection method is not limited in this invention; for example, it can be a bolt connection or an adhesive connection. The bracket 300 is used to fix the inspection unit 400 near the second hollow unit 212a, facilitating the inspection unit 400 to determine whether the piston 220 is located at the second hollow unit 212a. By adding an inspection unit 400, the state of the piston 220 can be acquired and judged in a timely manner, and combined with the contact state of the energized relay 110, it can be determined whether the movement of the piston 220 is abnormal. For example, if the controller 500 controls the contacts of the energized relay 110 to close, but the inspection unit 400 does not detect the piston 220 at the second cutout unit 212a, it proves that the cigarette blocking plate 20 needs to be opened. However, the piston 220 is still pressing against the cigarette blocking plate 20, and the oscillator in the blocking magnet 200 is not oscillating, causing the cigarette to not fall smoothly. Thus, the inspection unit 400 can most efficiently and accurately prove whether there is an abnormality in the current cigarette blocking, thereby demonstrating the detection reliability of the tray loading system detection device 10.

[0039] Furthermore, the circuit switch 100 also includes a delay relay 120. The delay relay 120 has a slower response time than the energized relay 110. The specific response delay time can be 0.1s or 0.5s, etc., and can be adaptively adjusted according to actual needs. The delay relay 120 includes a second input terminal 120a and a second output terminal 120b. The checking unit 400 includes a fourth input terminal 400a and a third output terminal 400b, and the controller 500 also includes a fifth input terminal 500b. Specifically, the fourth output terminal 500a is connected to the second input terminal 110a, and the controller 500 can control the contact of the delay relay 120 to close. Furthermore, the second output terminal 120b is connected to the fourth input terminal 400a. After the contacts of the delay relay 120 close, in the response state, the checking unit 400 checks whether a piston 220 exists at the second hollow unit 212a. Furthermore, the third output terminal 400b is connected to the fifth input terminal 500b, and the controller 500 obtains the inspection signal from the inspection unit 400 and determines whether the state of the piston 220 is abnormal based on the inspection signal.

[0040] Further reference Figure 1 and Figure 2 As shown, the fourth output terminal 500a is connected to both the first input terminal 110a and the second input terminal 110a. This means that both the energized relay 110 and the delay relay 120 are connected to a signal input point of the controller 500. The controller 500 simultaneously transmits the contact engagement command to both the energized relay 110 and the delay relay 120. The energized relay 110 responds immediately, adjusting the piston 220 of the blocking magnet 200; while the delay relay 120 controls the inspection unit 400 to check whether the piston 220 is at the second cutout unit 212a slightly later. This prevents the inspection unit 400 from transmitting a signal indicating an abnormality in the piston 220 before it has moved to the second cutout unit 212a, which could lead to an abnormal judgment of the cigarette blocking status and affect normal production.

[0041] In summary, this utility model embodiment provides a tray-loading system detection device. By adding an inspection unit and a delay relay, the accuracy of the detection can be improved. The inspection unit is located on the side of the second bottom surface away from the first bottom surface. This inspection unit can detect whether the piston has moved to the second hollowed-out unit and transmit the corresponding signal to the controller to determine the movement of the piston and thus whether there is any blockage of cigarettes. Adding an inspection unit allows for the determination of the piston's movement, and this determination improves the accuracy of the tray-loading system detection device. Simultaneously, it can also eliminate wrinkled and broken cigarettes caused by blockage in the cigarette storage, improve production efficiency, and reduce waste smoke disposal.

[0042] Continue to refer to Figures 1 to 4 As shown, the inspection unit 400 includes an oscillator proximity switch.

[0043] Among them, the oscillator proximity switch is a special type of proximity switch. An oscillator is a device capable of generating alternating electrical signals. A proximity switch is a switch that can detect the position or travel of a moving part without mechanical contact with it. That is, the oscillator proximity switch can detect whether the piston 220 has moved to the second hollow unit 212a without direct contact with the piston 220. Specifically, the oscillator proximity switch utilizes the oscillation characteristics of the oscillator to achieve the proximity detection function.

[0044] When the inspection unit 400 functions as an oscillator proximity switch, it can detect whether the piston 220 is located at the second hollow unit 212a without contacting the piston 220. For example, when the delay relay 120 drives the inspection unit 400 to inspect the piston 220, if the piston 220 is in... Figure 1 In this state, the inspection unit 400 transmits an inspection signal to the controller 500. The controller 500 can determine that the piston 220 is in an abnormal state, that is, the energizing relay 110 has not transmitted a signal to the blocking magnet 200, and the piston 220 has not moved downward. If the delay relay 120 drives the inspection unit 400 to inspect the piston 220, and the piston 220 is in an abnormal state... Figure 2 In the current state, the inspection unit 400 transmits the inspection signal to the controller 500. The controller 500 can determine that the piston 220 is in a normal state, that is, the energized relay 110 transmits the signal to the blocking magnet 200, the piston 220 moves downward, and the cigarette can fall normally through the cigarette blocking plate 20.

[0045] Figure 5 This is a schematic diagram of the structure of another tray loading system detection device provided in this embodiment of the utility model, for reference. Figure 5As shown, the tray loading system detection device 10 also includes an optocoupler 600, which includes a first connection terminal 601 and a second connection terminal 602. The first connection terminal 601 is connected to the third output terminal 400b, and the second connection terminal 602 is connected to the fifth input terminal 500b.

[0046] An optocoupler is a semiconductor device that couples and transmits electrical, optical, and electronic signals. (Reference) Figure 5 As shown, the tray loading system testing device 10 also includes an optocoupler 600. The first connection terminal 601 of the optocoupler 600 is connected to the third output terminal 400b of the inspection unit 400, and the second connection terminal 602 of the optocoupler 600 is connected to the fifth input terminal 500b of the controller 500. By adding an optocoupler 600 between the inspection unit 400 and the controller 500, the stability and reliability of signal transmission can be ensured, further improving the testing effect of the tray loading system testing device 10.

[0047] Optional, continue to refer to Figures 1 to 5 As shown, the oscillator proximity switch includes an NPN normally closed proximity switch.

[0048] Specifically, the oscillator proximity switch can be an NPN normally closed proximity switch. An NPN normally closed proximity switch is a proximity switch that is closed when no object is nearby and open when an object is nearby. Internally, it is equivalent to an NPN transistor. When no target object is nearby, the transistor is in the conducting state, the signal output line (OUT) is connected to GND (0V), and a low-level signal is output. When a target object enters the sensing range, the proximity switch's induction coil generates an electromagnetic field that interacts with the object, causing a change in the internal circuit state. The NPN transistor changes from conducting to cutoff, the signal output line (OUT) is disconnected from GND (0V), and the output terminal becomes a high-impedance state, equivalent to the circuit being open.

[0049] Continue to refer to Figures 1 to 4 As shown, the inspection unit 400 includes an image acquisition unit.

[0050] Continue to refer to Figures 1 to 4 As shown, the inspection unit 400 can be an image acquisition unit, which can acquire the image at the second cutout unit 212a. The inspection unit 400 is connected to the controller 500, and can directly transmit the image information at the second cutout unit 212a to the controller 500. The controller 500 then determines whether the piston 220 exists based on the image information.

[0051] Optionally, the image acquisition unit includes a laser image acquisition unit.

[0052] Furthermore, the image acquisition unit can be a laser image acquisition unit, which detects the second hollow unit 212a by emitting and receiving laser light. Using laser emission and reception avoids the problem of unclear image acquisition caused by insufficient ambient light at the second hollow unit 212a.

[0053] Figure 6 This is a schematic diagram of the structure of another tray loading system detection device provided in this embodiment of the utility model. Figure 7 This is an electrical control schematic diagram provided by an embodiment of the present utility model, for reference. Figure 6 and Figure 7 As shown, the tray loading system detection device 10 also includes a photoelectric switch 700, which is located on the side of the cigarette blocking plate 20 away from the blocking magnet 200. The photoelectric switch 700 includes a fifth output terminal 700a, and the controller 500 also includes a sixth input terminal 500c. The fifth output terminal 700a and the sixth input terminal 500c are connected.

[0054] Further reference Figure 6 As shown, the tray loading system detection device 10 also includes a photoelectric switch 700, which is located on the side of the cigarette blocking plate 20 away from the blocking magnet 200. The photoelectric switch 700 is a sensor that converts light signals into electrical signals. Specifically, the photoelectric switch 700 can be used to detect whether there is an accumulation of cigarettes on the side of the cigarette blocking plate 20 away from the blocking magnet 200, and the photoelectric switch 700 can transmit the signal to the controller 500.

[0055] Specifically, the photoelectric switch 700 is used to detect whether there is a buildup of cigarettes at the cigarette blocker 20 on the side away from the blocking magnet 200. If there is a buildup of cigarettes at the cigarette blocker 20 on the side away from the blocking magnet 200, the controller 500 can determine that there is a cigarette blockage based on the signal transmitted by the photoelectric switch 700. If there is no buildup of cigarettes at the cigarette blocker 20 on the side away from the blocking magnet 200, the controller 500 can determine that there is no cigarette blockage based on the signal transmitted by the photoelectric switch 700, and the cigarette can fall normally.

[0056] The tray loading system detection device 10 provided in this embodiment of the utility model can detect the position of the piston 220 through the inspection unit 400, and the controller 500 determines whether the cigarettes are blocked based on the detection results. Furthermore, the tray loading system detection device 10 is further equipped with a photoelectric switch 700, which is used to determine whether there is an accumulation of cigarettes at the cigarette blocking plate 20, making the detection process of the tray loading system detection device 10 more reliable.

[0057] Optional, see reference Figure 7As shown, 121 is the contact switch of the delay relay 120, and 122 is the coil of the delay relay 120. The photoelectric switch 700 can be installed at the highest point of the equipment's cigarette storage compartment, where cigarettes fall via the cigarette blocking plate 20. The controller 500 can be a programmable logic controller (PLC). When the photoelectric switch 700 transmits the detected signal to the controller 500, the controller 500 determines that the photoelectric switch 700 has detected a cigarette and will stop the equipment and report a cigarette tray blockage fault. Furthermore, the inspection unit 400 can be an NPN normally closed proximity switch. When the inspection unit 400 detects the piston 220 at the second cutout unit 212a, the signal is transmitted to the controller 500 via the optocoupler 600, and the controller 500 will not send a stop signal. When the inspection unit 400 does not detect the piston 220 at the second cutout unit 212a, the signal is transmitted to the controller 500 via the optocoupler 600, and the controller 500 will issue a stop signal to stop the equipment and report a cigarette tray blockage fault. The delay relay 210 has a pair of contacts used to connect the optocoupler 600, and the set delay connection time can be 0.1S or 0.5S, etc. Q0.2 is a signal input point; when the device starts, it sends a signal to the delay relay 210 and the energizing relay 210. Figure 7 (The energized relay 210 is not shown in the diagram).
