Description

Technical Field

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

[0002] Currently, the FOCKE350 packaging machine's main unit performs all defective item detection and rejection at the same rejection port. During normal operation, the rejection solenoid valve is energized, engaging the elevator and main unit, and the cigarette packs are lifted by the elevator into the drying wheel for further packaging. When a defective cigarette pack needs to be rejected, the rejection solenoid valve is de-energized, disengaging from the mechanism and pressing against the elevator. The elevator then lifts, but the cigarette pack is not lifted and instead moves backward into the rejection box.

[0003] However, after long-term operation of the equipment, the disengagement mechanism will wear out. When removing the cigarette pack, it will not be able to hold the elevator, and the resistance elevator will lift it, causing the defective cigarette pack to be lifted into the drying wheel and enter the next process, resulting in a quality accident.

[0032] Figure 1 This is a schematic diagram of a rejection failure detection device according to an embodiment of the present invention. Figure 2 This is a connection diagram of a rejection failure detection device according to an embodiment of the present utility model. (In conjunction with...) Figure 1 and Figure 2 As shown, the rejection failure detection device of the packaging machine includes: an inductive sensor 1 and a control unit 2;

[0033] The packaging machine includes a lifting assembly 3, a disengagement mechanism 4, and a main unit 6; the lifting assembly 3 is used to swing on a first plane to carry and convey cigarette packs 5;

[0034] The power-off output terminal of the host 6 is electrically connected to the power-off receiving terminal of the disengagement mechanism 4, and the rejection output terminal I1.3 is electrically connected to the rejection receiving terminal I0.3 of the control unit 2. The power-off output terminal is used to output a power-off signal to the power-off receiving terminal to control the disengagement mechanism 4 to move along the first direction x and abut against the lifting assembly 3 at the first position, so that the lifting assembly 3 stops swinging. The first direction x is on the first plane. The rejection output terminal I1.3 is used to output a rejection signal to the rejection receiving terminal I0.3.

[0035] The inductive sensor 1 is installed on the packaging machine and the detection range of the inductive sensor 1 includes the first position; the rejection detection output terminal I1.2 of the inductive sensor 1 is electrically connected to the rejection detection receiving terminal I0.2 of the control unit 2, and is used to output a rejection detection signal to the control unit 2 when the disengagement mechanism 4 and the lifting assembly 3 abut against each other at the first position;

[0036] Control unit 2 is used to determine that rejection has failed when a rejection signal is received but no rejection detection signal is received.

[0037] The packaging machine is used for packaging inspection of cigarette packs 5. The packaging machine includes a lifting assembly 3, a disengagement mechanism 4, and a main unit 6. The main unit 6 is used for signal processing, reception, and control. The lifting assembly 3 carries the cigarette packs 5 and transports them to the corresponding positions. The disengagement mechanism 4 prevents the lifting assembly 3 from swinging during the rejection of cigarette packs 5. Specifically, during normal operation, the lifting assembly 3 swings on the first plane, thus carrying and transporting the cigarette packs 5 to the drying roller for subsequent packaging. Each swing of the lifting assembly 3 transports one cigarette pack 5 to the drying roller, and this cycle repeats until all cigarette packs 5 are transported. Simultaneously, during normal operation, the main unit 6 controls the disengagement mechanism 4 to be energized. The disengagement mechanism 4 and the lifting assembly 3 do not interfere with each other, ensuring the smooth transport of the cigarette packs 5. However, when the packaging machine rejects cigarette pack 5, the power failure output terminal of the main unit 6 outputs a power failure signal to the power failure receiving terminal of the disengagement mechanism 4. At this time, the disengagement mechanism 4 loses power and moves along the first direction x, which conflicts with the movement direction of the lifting component 3 swinging on the first plane. This causes the disengagement mechanism 4 to abut against the lifting component 3, thus preventing the lifting component 3 from swinging. At this time, the lifting component 3 stops swinging, thus preventing the cigarette pack 5 from entering the drying wheel and entering the rejection box.

[0038] In order to detect the rejection effect of the detachment mechanism 4, the technical solution of this utility model embodiment sets up an inductive sensor 1 and a control unit 2, and electrically connects the rejection output terminal I1.3 of the host 6 to the rejection receiving terminal I0.3 of the control unit 2. When the host 6 controls the packaging machine to perform rejection action, the rejection output terminal I1.3 simultaneously outputs a rejection signal to the rejection receiving terminal I0.3, so that the control unit 2 can detect whether rejection has failed.

[0039] The inductive sensor 1 is installed on the packaging machine. Its detection range includes the first position, allowing it to detect in real time whether the disengagement mechanism 4 is in contact with the lifting assembly 3 at that position. Specifically, during normal operation of the packaging machine, the lifting assembly 3 will also swing past the first position, but the rejection detection signal acquired by the inductive sensor 1 is non-continuous and periodic. When the disengagement mechanism 4 comes into contact with the lifting assembly 3 at the first position, the lifting assembly 3 stops at that position. At this time, the inductive sensor 1 continuously acquires the rejection detection signal and inputs it to the rejection detection receiver I0.2 of the control unit 2.

[0040] When the control unit 2 receives both the rejection signal and the rejection detection signal, it determines that the packaging machine has completed the rejection of the cigarette pack 5. When the control unit 2 only receives the rejection signal but does not receive the rejection detection signal, the rejection of the packaging machine fails, that is, the disengagement mechanism 4 does not prevent the lifting component 3 from swinging.

[0041] For example, during normal operation of the packaging machine, the inductive sensor 1 monitors the operating status of the lifting assembly 3 in real time. When the lifting assembly 3 reaches the first position, the inductive sensor 1 collects a high-level signal and sends it to the control unit 2. When the packaging machine rejects a cigarette pack, the host 6 transmits a rejection signal to the control unit 2. At the same time, when the control unit 2 receives the rejection detection signal transmitted by the inductive sensor 1, it is considered that the disengagement mechanism 4 and the lifting assembly 3 are in contact at the first position, thus completing the rejection of the cigarette pack 5. However, if the control unit 2 does not receive the rejection detection signal transmitted by the inductive sensor 1 and instead receives a brief high-level signal, it is considered that the disengagement mechanism 4 has not contacted the lifting assembly, and the rejection fails.

[0042] The technical solution of this utility model embodiment is to set an inductive sensor 1 and a control unit 2 in the packaging machine. The inductive sensor 1 can detect in real time whether the detachment mechanism 4 is in contact with the lifting component 3. At the same time, the control unit 2 makes a judgment, realizing the real-time detection of rejection failure, and preventing defective cigarette packs 5 from entering the next process and causing quality accidents.

[0043] Optional, continue to refer to Figure 1 and Figure 2As shown, the rejection failure terminal Q0.2 of the control unit 2 is electrically connected to the alarm terminal Q1.2 of the packaging machine. When rejection failure is detected, the control unit 2 outputs a rejection failure signal to the packaging machine to control the packaging machine to alarm.

[0044] Among them, the rejection failure terminal Q0.2 can be used to output a rejection failure signal to the alarm terminal Q1.2 of the packaging machine when rejection failure is judged, so that the packaging machine can alarm in time, reminding the staff to check for abnormalities and prevent quality accidents.

[0045] In some embodiments, when rejection is determined to be invalid, the packaging machine can be stopped to prevent the cigarette pack 5 from flowing into the next process and ensure product quality.

[0046] The technical solution of this utility model embodiment is to set a rejection failure terminal Q0.2 on the control unit 2, and electrically connect the rejection failure terminal Q0.2 to the alarm terminal Q1.2. After detecting rejection failure, the rejection failure signal is input to the alarm terminal Q1.2 to control the packaging machine to alarm, so as to promptly remind the staff to check for abnormalities and prevent defective products from flowing into the subsequent process.

[0047] Optional, continue to refer to Figure 1 and Figure 2 As shown, the control unit 2 also includes a phase pulse terminal I0.0 and an index pulse terminal I0.1;

[0048] The main encoder 60 of the packaging machine is connected to the phase pulse terminal I0.0 and the index pulse terminal I0.1 respectively.

[0049] The phase pulse terminal I0.0 and the index pulse terminal I0.1 can be used to process and acquire the phase pulse signal of the host encoder 60, and calculate the operating degree of the packaging machine based on the phase pulse signal, so as to monitor the operating status of the packaging machine in a timely manner.

[0050] For example, the phase pulse terminal I0.0 and the index pulse terminal I0.1 of the control unit 2 can be connected to the host encoder 60 respectively. The phase pulse terminal I0.0 transmits the indication pulse signal, and the index pulse terminal I0.1 transmits the index pulse signal, thereby calculating the 0°-360° phase of the packaging machine and ensuring the normal operation of the packaging machine.

[0051] Optionally, the rejection detection signal can be a continuous high-level signal.

[0052] In the normal rejection state, since the detachment mechanism 4 continuously abuts against the lifting component 3 for a period of time, the inductance sensor 1 continuously detects the presence of the lifting component 3 at the first position, so the rejection detection signal is a continuous high-level signal.

[0053] Understandably, during the operation of the packaging machine, the swing of the lifting component 3 will also pass through the first position. At this time, the inductive sensor 1 will also output a high-level signal to the control unit 2. However, the signal at this time is discontinuous and brief. When a continuous high-level signal appears, it is judged as normal rejection, which ensures timely detection of faults and ensures the normal operation of the packaging machine.

[0054] Optionally, the disengagement mechanism 4 includes a solenoid valve;

[0055] The power failure signal is used to control the solenoid valve to lose power.

[0056] The host 6 can achieve the purpose of control and rejection based on the different running directions of the valve core when the solenoid valve is energized and de-energized.

[0057] Specifically, under normal operating conditions of the packaging machine, the solenoid valve is energized, and the valve core moves in the second direction y. The disengagement mechanism 4 and the lifting component 3 are not in contact. At this time, the lifting component 3 swings at a set angle. When the packaging machine rejects a product, the main unit 6 controls the solenoid valve to de-energize and outputs a de-energization signal to the solenoid valve. The solenoid valve is de-energized, and the valve core moves in the first direction x. At this time, the lifting component 3 and the disengagement mechanism 4 are in contact, thereby preventing the lifting component 3 from swinging and lifting.

[0058] The technical solution of this utility model embodiment is to set a solenoid valve in the disengagement mechanism 4, and control the rejection action by controlling the energization and de-energization of the solenoid valve. This simplifies the device while achieving the rejection purpose and ensuring the normal operation of the packaging machine.

[0059] Optional, continue to refer to Figure 1 and Figure 2 As shown, the control unit 2 is installed in the electrical cabinet of the packaging machine and is electrically connected to the power supply in the electrical cabinet.

[0060] The control unit 2 is installed in the electrical cabinet of the packaging machine to facilitate electrical connection with the power supply in the electrical cabinet and to provide power to the control unit 2.

[0061] In some embodiments, the power supply voltage in the electrical cabinet is 24V. The first power supply terminal of the control unit 2 is electrically connected to the 24V power supply line, and the second power supply terminal is electrically connected to the -24V power supply line, ensuring the normal operation of the rejection failure detection device.

[0062] Optional, Figure 3 This is an installation diagram of an inductor sensor 1 according to an embodiment of the present invention, as shown below. Figure 3 As shown, it also includes a mounting bracket 77; the mounting bracket 7 includes a through hole 70;

[0063] One end of the mounting bracket 7 is fixed to the housing of the packaging machine with screws, and the inductive sensor 1 is fixed to the mounting bracket 7 through the through hole 70.

[0064] In order to ensure the stability of the position of the inductive sensor 1, a mounting bracket 7 is set in the rejection failure detection device. One end of the mounting bracket 7 is fixed to the housing of the packaging machine with screws, and the inductive sensor 1 is fixed on the mounting bracket 7, which ensures the stability of the position of the inductive sensor 1 and is conducive to the accuracy of the rejection failure detection device.

[0065] In some embodiments, the inductive sensor 1 includes a detection end and a power supply end; the detection end faces the first plane, and the power supply end faces away from the first plane. The detection end can be used to detect the lifting component 3, and facing the first plane is intended to cover the first position in terms of detection range; the power supply end faces away from the first plane to connect to a power source for wiring.

[0066] The technical solution of this utility model embodiment is to set up a mounting bracket 7, fix one end of the mounting bracket 7 to the housing of the packaging machine with screws, and fix the inductive sensor 1 on the mounting bracket 7, so that the inductive sensor 1 is stably fixed on the packaging machine through the mounting bracket 7, ensuring the stability during the detection process, while not affecting the normal operation of the packaging machine, which is beneficial to the accuracy of the rejection detection device.

[0067] Optional, continue to refer to Figure 3 As shown, the mounting bracket 7 includes a first portion 71 and a second portion 72; the first portion 71 and the second portion 72 are connected and have an included angle of 90°.

[0068] The first part 71 includes a through hole 70, and the second part 72 is fixed to the housing of the packaging machine by screws.

[0069] The first portion 71 is used to fix the inductive sensor 1. The first portion 71 includes a through hole 70, into which the inductive sensor 1 can be inserted for fixation. The second portion 72 is used to connect to the housing of the packaging machine. When the second portion 72 is fixed to the housing of the packaging machine with screws, the position of the through hole 70 is fixed, thus fixing the position of the inductive sensor 1. The first portion 71 and the second portion 72 are connected at a 90° angle to facilitate stable installation of the inductive sensor 1.

[0070] It is understood that the packaging machine in this embodiment of the present invention may be a FOCKE350 model packaging machine or other models of packaging machine, and this embodiment of the present invention does not limit it.

[0071] The technical solution of this utility model embodiment is to set an inductive sensor 1 and a control unit 2 in the packaging machine. The inductive sensor 1 can detect in real time whether the detachment mechanism 4 is in contact with the lifting component 3. At the same time, the control unit 2 makes a judgment, realizing the real-time detection of rejection failure, and preventing defective cigarette packs 5 from entering the next process and causing quality accidents.

[0072] 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.

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.
