Mechanically triggered loose-pack stop device and transparent paper packaging machine

Abstract

This utility model relates to the field of cigarette packaging technology, and discloses a mechanically triggered loose-pack stop device and a transparent paper packaging machine. A rotating shaft is rotatably positioned at the outlet of the packaging forming wheel. The rotating shaft can rotate to lift one end of a trigger element, connecting it to a stop detection and control unit. The stop detection and control unit can selectively activate to control the transparent paper packaging machine to stop. One end of a movable bracket is fixed radially to the rotating shaft, and the end of the movable bracket away from the rotating shaft has a preset gap with the cigarette packs output from the packaging forming wheel. When the movable bracket contacts the loose transparent packaging paper, it drives the rotating shaft to rotate. If a defective cigarette pack is produced, the stop detection and control unit is immediately triggered, and the transparent paper packaging machine stops promptly and removes the defective cigarette pack. This effectively avoids the production of defective cigarette packs with inadequate transparent paper packaging on the outside of the box. Furthermore, the manufacturing cost is low, and subsequent maintenance is simple; only checking whether the movable bracket has been deformed due to the impact of the defective cigarette pack is required.

Description

Technical Field

[0001] This utility model relates to the field of cigarette box packaging technology, and in particular to a mechanically triggered loose-pack stop device and a transparent paper packaging machine. Background Technology

[0002] Currently, a set of medium-speed hard-pack packaging machines used in tobacco production plants includes several parts such as the YB45 small box packaging machine, the YB55 small box transparent paper packaging machine, the YB65 carton paper packaging machine, and the YB95 carton transparent paper packaging machine. After the small box packaging machine or carton packaging machine completes the packaging, the cigarette packs enter the transparent paper packaging machine through the cigarette pack drying conveyor channel. The transparent paper packaging machine mainly wraps the produced cigarette packs with transparent paper on the outside of the box. The cigarette packs wrapped with transparent paper can effectively prevent moisture and aroma loss.

[0003] During the packaging process of the transparent paper packaging machine, it was discovered that occasionally, the transparent paper on the outside of the cigarette packs was not properly wrapped, causing the cigarette packs to be exposed, a quality problem commonly known as "loose packs." Currently, the transparent paper packaging machine uses an image acquisition camera to visually capture images of the transparent paper wrapping on the outside of the box. If any loose packs are found, they will be rejected at the rejection baffle, without stopping the machine.

[0004] However, this method is not reliable enough. The image acquisition camera is expensive to manufacture, complex to maintain, and easily gets dirty, complicating the operator's maintenance procedures and reducing equipment production efficiency to some extent. If a defective cigarette pack is not detected by the camera due to camera damage, it cannot be rejected and will not proceed to the next process; similarly, if the cylinder of the rejection baffle is damaged, the defective cigarette pack will not be rejected according to the preset process, thus allowing it to proceed to the next process. Exposed cigarette packs that are not tightly wrapped in transparent paper will cause the cigarettes to become damp and lose their aroma, and these problems are difficult for operators to detect after entering the next process, making them easy to enter the market and posing a significant quality risk. Utility Model Content

[0005] The purpose of this utility model is to provide a mechanically triggered loose-pack stop device and a transparent paper packaging machine, which has a simple structure, low manufacturing cost, and easy maintenance; it stops the machine immediately when a bad cigarette pack appears, without waiting for visual detection of the bad cigarette pack, providing sufficient time to remove it and ensure product quality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A mechanically triggered bulk packaging shutdown device includes:

[0008] A rotating shaft is fixedly equipped with a trigger element. The rotating shaft can rotate so that one end of the trigger element is connected to a stop detection and control unit. The stop detection and control unit can control the transparent paper packaging machine to stop.

[0009] A movable support is provided, one end of which is fixed radially to the rotating shaft. The end of the movable support away from the rotating shaft has a preset gap with the cigarette pack output by the packaging forming wheel. When the cigarette pack has open transparent packaging paper, the movable support contacts the open transparent packaging paper so that the movable support drives the rotating shaft to rotate.

[0010] As an optional technical solution for the mechanically triggered loose-pack stop device, the movable support is configured as a U-shaped frame, with two legs at the opening of the U-shaped frame. The two legs pass through the rotating shaft, and the preset gap is located between the bottom of the U-shaped frame and the cigarette packs output by the packaging forming wheel.

[0011] As an optional technical solution for the mechanically triggered loose-pack stop device, the two support legs are provided with the same bending angle. The larger the bending angle, the closer the bottom of the U-shaped frame is to the cigarette pack, and the smaller the preset gap.

[0012] As an optional technical solution for the mechanically triggered bulk bag stopping device, the mechanically triggered bulk bag stopping device also includes a fixing member, which passes through the support leg and the rotating shaft.

[0013] As an optional technical solution for a mechanically triggered bulk bag shutdown device, the rotating shaft includes a first section, a middle section, and a tail section that are integrally formed and connected in sequence. The middle section is a regular square prism, and the first and tail sections are both cylinders. The first section, the middle section, and the tail section are coaxially arranged.

[0014] As an optional technical solution for a mechanically triggered bulk packaging shutdown device, both the first and last sections are equipped with bearing components.

[0015] As an optional technical solution for a mechanically triggered bulk packaging shutdown device, the minimum trigger angle of the rotating shaft is a preset angle, and a preset distance is provided between the trigger and the shutdown detection and control unit. The product of the sine of the preset angle and the length of the trigger is greater than the preset distance.

[0016] As an optional technical solution for a mechanically triggered bulk packaging shutdown device, the shutdown detection and control unit is equipped with an indicator light, the trigger is connected to the shutdown detection and control unit, and the indicator light is illuminated.

[0017] A transparent paper packaging machine, including any of the mechanically triggered loose-package shutdown devices described above.

[0018] As an optional technical solution for the transparent paper packaging machine, the transparent paper packaging machine also includes a mechanical pick-up arm. The stop detection control unit is communicatively connected to the mechanical pick-up arm. When the stop detection control unit is started, the mechanical pick-up arm clamps and removes the cigarette pack located at the outlet of the packaging forming wheel.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a mechanically triggered loose-pack stop device, comprising a rotating shaft and a movable support. The rotating shaft is rotatably positioned at the outlet of the packaging forming wheel. A trigger is fixedly mounted on the rotating shaft, allowing it to rotate so that one end of the trigger is raised and connected to a stop detection and control unit. The stop detection and control unit can selectively activate to control the transparent paper packaging machine to stop. One end of the movable support is fixed radially to the rotating shaft, and the end of the movable support away from the rotating shaft has a preset gap with the cigarette packs output by the packaging forming wheel. When loose transparent packaging paper adheres to the outside of the cigarette pack, the movable support contacts the loose transparent packaging paper, causing the movable support to drive the rotating shaft to rotate. If a defective cigarette pack is produced, the stop detection and control unit is immediately triggered, and the transparent paper packaging machine promptly reports an error and stops operating. This gives the operator ample time to remove the defective cigarette pack and check for equipment damage, thus preventing product quality defects and effectively maintaining brand image. By using this mechanically triggered loose-pack stop device, the generation of defective cigarette packs with inadequate transparent paper packaging can be effectively prevented. It also has low manufacturing costs and is easy to maintain; only checking whether the movable support has been deformed by the impact of the defective cigarette pack is required.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] like Figure 1As shown, this utility model discloses a mechanically triggered loose pack stopping device and a transparent paper packaging machine including the mechanically triggered loose pack stopping device. The transparent paper packaging machine lifts the cigarette packs together with the transparent paper to a horizontal channel through an elevator. On the horizontal channel, the transparent paper is folded by a spiral corner folder and sent to the outlet of the packaging forming wheel. Then, the cigarette packs are sent along the conveying channel to the soldering iron to heat and pressurize the end face at regular intervals to complete the heat sealing of the transparent paper on the end face of the cigarette pack. The mechanically triggered loose-pack stop device is designed and installed on the upper part of the spiral corner bender, including a rotating shaft 100 and a movable bracket 200. The rotating shaft 100 is rotatably set at the outlet of the packaging forming wheel. A trigger 140 is fixedly installed on the rotating shaft 100. The rotating shaft 100 can rotate so that one end of the trigger 140 is raised and connected to the stop detection control unit. The stop detection control unit can selectively start to control the transparent paper packaging machine to stop. One end of the movable bracket 200 is fixed to the rotating shaft 100 radially. The end of the movable bracket 200 away from the rotating shaft 100 has a preset gap with the cigarette pack output by the packaging forming wheel.

[0031] The transparent paper packaging machine also includes a mechanical pickup arm. The shutdown detection control unit is connected to the mechanical pickup arm. When a bad cigarette pack is detected, the shutdown detection control unit is activated, and the mechanical pickup arm can promptly pick up and remove the bad cigarette pack currently located at the exit of the packaging forming wheel, realizing automated processing, improving the equipment efficiency and safety of the transparent paper packaging machine, and reducing labor input costs.

[0032] After the cigarette packs are wrapped by the packaging forming wheel, they are output horizontally. The specifications of the sliding bracket are determined based on the cigarette pack's movement trajectory, the requirements of the transparent paper wrapping on the outside of the pack, and the dimensions of the output channel, to achieve the expected conditions for triggering the machine's stop detection. When the cigarette pack has loose transparent paper attached, or when the packaging forming wheel outputs a "loose pack" or other deformed or defective cigarette pack, the movable bracket 200 contacts the loose transparent paper, causing the movable bracket 200 to drive the rotating shaft 100 to rotate. This immediately triggers the stop detection control unit, and the transparent paper packaging machine promptly reports an error and stops operating. This gives the operator ample time to remove the defective cigarette pack and check for equipment damage, preventing the end-sealing soldering iron of the transparent paper packaging machine from shifting or deforming due to the impact of the defective cigarette pack.

[0033] When operating normally without loose packs, a preset gap exists between the movable support 200 and the cigarette packs output after being wrapped by the packaging forming wheel. The movable support 200 is stationary. In this state, the outer transparent paper of the box will not touch the movable support 200, so it is not lifted and the stop detection control unit is not triggered, allowing the transparent paper packaging machine to operate normally. However, when a cigarette pack is not properly wrapped by the outer transparent paper, the messy, wrinkled paper will cause the cigarette pack to rise at a certain angle, just filling the gap between the movable support 200 and the cigarette pack. This causes the movable support 200 to rise, lifting the trigger 140 and reaching the position to trigger the stop detection. Ultimately, this causes the transparent paper packaging machine to stop running with an error message, allowing operators to quickly identify and manually remove the defective cigarette packs, preventing product quality defects and effectively maintaining the brand image. Using this mechanically triggered loose pack stop device effectively prevents the generation of defective cigarette packs due to improperly wrapped outer transparent paper. It also has low manufacturing costs and is easy to maintain; only checking whether the movable support 200 has been deformed by the impact of the defective cigarette pack is required.

[0034] In this embodiment, the movable support 200 is configured as a U-shaped frame, which can be made of highly malleable iron wire to ensure its stability and lightness. Two support legs 210 are provided at the opening of the U-shaped frame, and the two support legs 210 pass through the rotating shaft 100. The U-shaped frame and the rotating shaft 100 are installed and can rotate coaxially with the rotating shaft 100. The preset gap is located between the bottom of the U-shaped frame and the cigarette pack output by the packaging forming wheel.

[0035] Furthermore, the two support legs 210 are set with the same bending angle, which can be bent to the corresponding angle according to different expected conditions to trigger the machine to stop detection. The bending angle depends on the degree of loosening of the bad cigarette pack. That is, the larger the bending angle, the smaller the preset gap, the smaller the gap between the movable support 200 and the cigarette pack, and the more sensitive the detection effect of bad cigarette pack.

[0036] It is understandable that the mechanically triggered bulk bag shutdown device also includes a fixing component 300. The fixing component 300 passes through both the support leg 210 and the rotating shaft 100 in a direction perpendicular to the support leg 210 through which the rotating shaft 100 passes. This can further fix the connection structure between the support leg 210 and the rotating shaft 100, prevent the support leg 210 from separating from the rotating shaft 100, and improve the structural stability of the mechanically triggered bulk bag shutdown device.

[0037] Specifically, the rotating shaft 100 includes a first section 110, a middle section 120, and a last section 130 integrally formed and connected in sequence. The middle section 120 is a regular square prism with square ends. The first section 110 and the last section 130 are both cylinders connected to square end faces. The first section 110, the middle section 120, and the last section 130 are coaxially arranged. For example, the support leg 210 can be inserted perpendicularly to one side of the square prism to mark the initial angle of the movable support 200.

[0038] Optionally, both the first section 110 and the last section 130 are equipped with bearing components. The inner ring of the bearing component is sleeved outside the rotating shaft 100, and the outer ring of the bearing component is embedded at the outlet of the packaging forming wheel. The inner and outer rings of the bearing component rotate relative to each other to ensure the rotational flexibility of the rotating shaft 100, protect the mechanically triggered bulk packaging stop device, reduce wear, and extend its service life.

[0039] In this embodiment, the minimum trigger angle of the rotating shaft 100 is the angle at which the rotating shaft 100 just contacts the stop detection control unit. It is predetermined to be a specific preset angle. A preset distance is set between the trigger 140 and the stop detection control unit. The product of the sine of the preset angle and the length of the trigger 140 needs to be greater than the preset distance to ensure that the trigger 140 can connect with the stop detection control unit in time when it is raised to the preset angle.

[0040] To further remind operators of the working status of the transparent paper packaging machine, an indicator light is installed on the stop detection control unit. If the trigger 140 is connected to the stop detection control unit, the indicator light will illuminate when the transparent paper packaging machine stops.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
