Description

Technical Field

[0001] This invention relates to the field of cigarette equipment technology, and more specifically, to a forced self-inspection device and method for cigarette packs on a conveyor belt. Background Technology

[0002] During the cigarette packaging production process, operators need to conduct regular self-inspections of the cigarette packs. Some cigarette companies require a 5-minute interval between self-inspections of individual packs. These self-inspections involve checking the appearance of the packs, such as the trademark, aluminum foil, and seals. However, in actual production, operators often cannot accurately determine the timing of these self-inspections, and the frequency varies from person to person, depending on individual awareness. Failure to conduct timely self-inspections can lead to significant quality risks. Furthermore, if the self-inspection period is too long, the quality of packs produced in a particular time period will lack inspection, resulting in a lack of quality control for that specific timeframe.

[0003] The existing technical solution involves setting a self-inspection reminder pop-up on the main control computer screen of the small box transparent paper packaging machine. Within a specified time, the pop-up reminds the operator to perform a self-inspection.

[0004] Therefore, how to provide a forced self-inspection device and method for cigarette packs on conveyor belts has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a forced self-inspection device and method for cigarette packs on a conveyor belt.

[0006] According to a first aspect of the present invention, a forced self-inspection device for cigarette packs on a conveyor belt is provided, comprising a push-pull sampling electromagnet, a first sensor, a sampling box, a second sensor, a cigarette pusher plate, a cigarette pusher cylinder, a solenoid valve, a counter, a controller, and an alarm device;

[0007] The push-pull sampling electromagnet is installed in the middle of the left side of the conveyor belt; the smoke-pushing cylinder is installed at the rear end of the right side of the conveyor belt; the solenoid valve is installed below the smoke-pushing cylinder and connected to the smoke-pushing cylinder through a pneumatic pipe; the sampling box is installed in front of the smoke-pushing cylinder; the smoke-pushing plate is installed inside the sampling box and connected to the front end of the smoke-pushing cylinder; the first sensor is installed at the front end of the sampling box; the second sensor is installed at a preset distance in front of the initial position of the smoke-pushing plate.

[0008] The counter is electrically connected to the controller, the push-pull sampling electromagnet is electrically connected to the controller, the solenoid valve is electrically connected to the controller, the first sensor and the second sensor are respectively electrically connected to the controller, and the alarm device is electrically connected to the controller.

[0009] Optionally, the device further includes: guard rails on both sides of the conveyor belt;

[0010] The guard rails on both sides of the conveyor belt are installed on both sides of the conveyor belt.

[0011] Optionally, the device further includes: a cigarette pack conveyor belt support;

[0012] The cigarette pack conveyor belt support is installed below the conveyor belt;

[0013] The guard rails on both sides of the conveyor belt are installed on both sides of the conveyor belt via the cigarette pack conveyor belt bracket;

[0014] The push-pull sampling electromagnet is installed on the middle of the left side of the conveyor belt via the cigarette pack conveyor belt bracket; the smoke-pushing cylinder is installed on the rear end of the right side of the conveyor belt via the cigarette pack conveyor belt bracket; the solenoid valve is fixed on the cigarette pack conveyor belt bracket via a mounting bracket and is installed below the smoke-pushing cylinder; the sampling box is installed in front of the smoke-pushing cylinder via the cigarette pack conveyor belt bracket.

[0015] Optionally, the sampling box can hold more than 5 small packs of cigarettes.

[0016] Optionally, the sampling box has dimensions of 600×80×40mm.

[0017] Optionally, a 120mm long notch is provided on the sampling box; in the pushing and pulling direction of the push-pull sampling electromagnet, the center of the notch coincides with the center of the push-pull sampling electromagnet.

[0018] According to a second aspect of the present invention, a method for forced self-inspection of cigarette packs on a conveyor belt is provided, comprising the forced self-inspection device for cigarette packs on a conveyor belt as described in any one of the first aspects of the present invention, the method comprising:

[0019] A counter is given a set value. When the preset detection time is reached, the controller outputs a control signal to the push-pull sampling electromagnet to perform a cigarette-pushing action. A small pack of cigarettes is pushed into the sampling box by the push-pull sampling electromagnet to complete the sampling of the cigarette pack. At this time, the controller outputs a signal to the solenoid valve. After the solenoid valve is energized, air is released. The cigarette-pushing cylinder at the rear of the sampling box is activated by the compressed air, pushing the cigarette-pushing plate forward and pushing the small pack of cigarettes forward. At the same time, the counter accumulates the number of cigarette packs. When the cigarette pack at the front of the sampling box is present, the first sensor detects the presence of the cigarette pack and inputs a high signal. A level signal is sent to the controller, which outputs an alarm signal to the alarm device. The alarm device then prompts the operator to perform a self-check. After the operator removes the frontmost cigarette pack, the device automatically resets, and the counter also resets. If the operator does not remove the frontmost cigarette pack, the alarm device continues to sound. When the cigarette pack accumulates to the position of the second sensor at the rear, the second sensor inputs a high-level signal to the controller, which outputs a stop signal to stop the packaging machine, forcing the operator to perform a self-check. This process continues until the frontmost cigarette pack is removed, at which point the device resets, completing the forced self-check of the manual cigarette packs.

[0020] According to the technical content disclosed in this invention, the following beneficial effects are achieved:

[0021] (1) It can automatically sample the cigarette packs passing on the conveyor belt, which makes it convenient for operators to perform self-inspection of the cigarette packs and improves the efficiency of self-inspection.

[0022] (2) The alarm device can remind the operator to perform self-inspection of the cigarette pack quality, ensure the quality of self-inspection of the small cigarette packs, and improve product quality;

[0023] (3) It can count cigarette packs at different time periods, so that operators can conduct quality inspections on the sampled cigarette packs at different time periods, avoiding the failure to conduct quality inspections of cigarette packs at the specified time periods due to operators' failure to conduct self-inspections at the specified time.

[0024] (4) If the operator fails to perform self-inspection within the specified maximum time, the output control signal will be used to stop the machine, forcing the operator to perform self-inspection of the product before restarting the machine. This will avoid major quality risks caused by failure to perform self-inspection for a long time, avoid product quality traceability due to inadequate self-inspection, save material consumption, and reduce production costs.

[0038] The sampling box 7 can hold more than 5 small cigarette packs 4. The dimensions of the sampling box 7 are 600×80×40mm. A 120mm long notch is provided on the sampling box 7; in the pushing and pulling direction of the push-pull sampling electromagnet 5, the center of the notch coincides with the center of the push-pull sampling electromagnet 5.

[0039] According to a second aspect of the present invention, a method for forced self-inspection of cigarette packs on a conveyor belt is provided, comprising the forced self-inspection device for cigarette packs on a conveyor belt as described in any one of Embodiments 1, the method comprising:

[0040] A counter is set to a value. When the preset detection time is reached, the controller outputs a control signal to the push-pull sampling electromagnet 5 to perform a cigarette-pushing action. A small pack of cigarettes 4 is pushed into the sampling box 7 by the push-pull sampling electromagnet 5 to complete the sampling of the cigarette pack. At this time, the controller outputs a signal to the solenoid valve 12. After the solenoid valve 12 is energized, air is released.

The device then resets, completing the forced self-check of the manual cigarette packs. Throughout the process, the operator can determine the number of cigarette packs sampled at different times based on the number of small cigarette packs 4 in the sampling box 7, thus inspecting the product quality.

[0041] In summary, the technical content disclosed in this invention can automatically sample cigarette packs passing on a conveyor belt, facilitating self-inspection by operators and improving inspection efficiency. An alarm device reminds operators to perform self-inspection of cigarette pack quality, ensuring the quality of small cigarette pack self-inspection and improving product quality. It can count cigarette packs at different times, allowing operators to inspect the quality of sampled small cigarette packs at different times, avoiding missed inspections due to operators not performing self-inspections within the specified time. If the operator fails to perform self-inspection within the specified maximum time, a control signal is output to stop the machine, forcing the operator to perform self-inspection before restarting, preventing significant quality risks caused by prolonged lack of self-inspection, avoiding product quality traceability issues due to inadequate self-inspection, saving material resources, and reducing production costs.
