Description

Technical Field

[0001] This utility model relates to the technical field of cigarette packaging production equipment, and in particular to a cigarette pack lifting channel for a Fock packaging machine. Background Technology

[0002] The FOKERFX2 packaging machine, during the packaging and conveying of small cigarette packs, pushes out six cigarette packs via a discharge pusher with an attached drying drum, and enters the synchronous conveyor belt. Two sets of stop blocks on the synchronous belt then feed the cigarette packs one by one into a vertically upward conveyor channel, followed by a horizontal conveyor channel. Both the vertical and horizontal conveyor channels have compressed air nozzles at the beginning to propel the cigarette packs forward. In actual production, when a cigarette pack becomes slightly deformed due to an abnormality, it experiences a delay when passing through the vertically upward channel, preventing smooth and stable forward transport. Meanwhile, subsequent cigarette packs continue to be fed in normally, causing an accumulation of cigarette packs in the vertical channel. This accumulation reaches the entrance of the vertically upward conveyor channel, where the cigarette packs at the entrance interfere with and collide with those conveyed by the synchronous conveyor belt, resulting in significant impact marks on the bottom of the small box and causing product quality defects. When a cigarette pack is severely deformed, the resistance in the vertical upward conveyor channel is high, requiring the synchronous conveyor belt to exert greater force to push it forward. In this case, the torque sensor detects that the torque exceeds the set value and sends a signal, causing the machine to stop. When a cigarette pack is only slightly deformed, the resistance in the vertical upward channel is still relatively high. In this case, the synchronous conveyor belt needs to exert greater force to transport the cigarette pack forward, but if the torque sensor detects a value below the set value, the machine will still operate normally. However, the cigarette packs will develop impact marks without any corresponding warning or timely reminder, posing a significant quality hazard.

[0003] Therefore, how to provide an improved conveying channel solution that can stably transport cigarette packs and provide timely warnings when smoke accumulates has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this utility model provides a cigarette pack lifting channel for a Fock packaging machine. By adding negative pressure suction in conjunction with the original track blowing, the conveying force of the cigarette packs is increased. Simultaneously, a photoelectric detection device is added to detect the cigarette packs within the channel, allowing for timely assessment of their condition and reducing the scrap rate. Specifically, the technical solution of this utility model to achieve the above objectives is as follows:

[0005] A cigarette pack lifting channel for a Fock packaging machine includes a conveyor belt, a vertical conveying channel, a horizontal conveying channel, a first air outlet, and a second air outlet. The conveyor belt is installed at the lower end inlet of the vertical conveying channel, and the horizontal conveying channel is installed at the upper end outlet of the vertical conveying channel. Cigarette packs are conveyed to the vertical conveying channel via the conveyor belt and then upwards to the horizontal conveying channel. The first air outlet is installed at the lower end inlet of the vertical conveying channel, providing an upward thrust to the cigarette packs entering the vertical conveying channel using high-pressure gas. The second air outlet is installed at the upper end outlet of the vertical conveying channel, providing a lateral thrust to the cigarette packs entering the horizontal conveying channel using high-pressure gas. The system also includes:

[0006] A negative pressure suction port is installed at the connection between the feed inlet of the horizontal conveying channel and the discharge outlet at the upper end of the vertical conveying channel, providing upward suction to the vertical conveying channel;

[0007] A one-way valve is installed at the inlet of the horizontal conveying channel and can be opened in the discharge direction of the horizontal conveying channel, allowing the smoke pack and airflow to pass through in one direction.

[0008] Furthermore, the one-way valve includes a valve housing and a channel baffle installed within the horizontal conveying channel; the upper surface of the valve housing is higher than the top of the horizontal conveying channel; the channel baffle is hinged to the top of the valve housing, and when the channel baffle is in its natural state, it is vertically downward and its surface is in contact with the horizontal conveying channel, and the surface of the channel baffle can completely block the horizontal conveying channel.

[0009] Furthermore, the inner surfaces of the vertical conveying channel and the horizontal conveying channel are provided with grooves along the conveying direction to reduce the contact surface and friction during the conveying of cigarette packs.

[0010] Furthermore, the upper section of the vertical conveying channel is equipped with a photoelectric detection device for detecting the conveying conditions inside the channel.

[0011] Furthermore, an observation window is provided on the upper section of the vertical conveying channel. The observation window includes a transparent cover plate perpendicular to the conveying channel, allowing the operator to observe the interior of the vertical conveying channel.

[0012] Furthermore, one end of the transparent cover is hinged to the vertical conveying channel, and the other end is provided with a latch that can be fastened to the vertical conveying channel.

[0013] Furthermore, a mounting frame is installed on the vertical conveying channel, and a photoelectric detection device is installed on the mounting frame to detect the interior of the channel through the transparent cover.

[0014] Furthermore, an audible and visual alarm device is also provided, which is connected to the photoelectric detection device.

[0015] Furthermore, both the vertical conveying channel and the horizontal conveying channel are provided with two parallel conveying paths.

[0016] The cigarette packs conveyed by conveyor belt 1 enter the vertical conveying channel 2. Air is ejected through the first jet nozzle 4 to power the vertically upward conveying of the cigarette packs. After reaching the horizontal conveying channel 3, air is ejected through the second jet nozzle 5 to power the horizontally conveying of the cigarette packs. A photoelectric detection device 7 monitors the interior of the channel through the transparent cover of the observation window 8. If there is a blockage, an audible and visual alarm device 10 is activated. The negative pressure suction port 6 draws in the vertically upward conveying cigarette packs using negative pressure. When the cigarette packs pass through the valve chamber 111, they break through the channel baffle 112 and are conveyed away. If the cigarette packs do not pass through, the channel baffle 112 naturally moves downward, its surface blocking the horizontal conveying channel 3, and the negative pressure suction port 6 continues to operate normally.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (i) The negative pressure pipeline design provides a new solution to the problem of cigarette pack delay and enhances the system's adaptability;

[0019] (ii) Through the application of photoelectric detection devices and audible and visual alarm devices, abnormal situations can be monitored and responded to;

[0020] (III) The structure is simple, practical and effective. The grooves on the inner side of the conveying channel along the conveying direction reduce the friction during the conveying of cigarette packs and improve the success rate of conveying. Attached Figure Description

Detailed Implementation

[0028] like Figure 1-5 As shown, the embodiments of this utility model are as follows:

[0029] A cigarette pack lifting channel for a Fock packaging machine includes a conveyor belt 1, a vertical conveying channel 2, a horizontal conveying channel 3, a first air outlet 4, a second air outlet 5, a negative pressure suction outlet 6, and a one-way valve 11.

[0030] Conveyor belt 1 is installed at the lower end inlet of vertical conveying channel 2, and horizontal conveying channel 3 is installed at the upper end outlet of vertical conveying channel 2. Cigarette packs are conveyed to vertical conveying channel 2 via conveyor belt 1, and then upwards to horizontal conveying channel 3. Grooves 12 are provided on the inner surfaces of both vertical and horizontal conveying channels 2 and 3 along the conveying direction to reduce the contact area and friction during cigarette pack conveying. Both vertical and horizontal conveying channels 2 and 3 have two parallel conveying paths. A first air jet 4 is installed at the lower end inlet of vertical conveying channel 2, providing upward thrust to the cigarette packs entering vertical conveying channel 2 using high-pressure gas; a second air jet 5 is installed at the upper end outlet of vertical conveying channel 2, providing lateral thrust to the cigarette packs entering horizontal conveying channel 3 using high-pressure gas.

[0031] A negative pressure suction port 6 is installed at the connection between the inlet of the horizontal conveying channel 3 and the outlet at the upper end of the vertical conveying channel 2, providing upward suction to the vertical conveying channel 2. A one-way valve 11 is installed at the inlet of the horizontal conveying channel 3, which can open in the discharge direction of the horizontal conveying channel 3, allowing the smoke pack and airflow to pass in one direction. The one-way valve 11 includes a valve chamber 111 and a channel baffle 112 installed inside the horizontal conveying channel 3. The upper surface of the valve chamber 111 is higher than the top of the horizontal conveying channel 3. The channel baffle 112 is hinged to the top of the valve chamber 111. When the channel baffle 112 is in its natural state, it is vertically downward and its surface is in contact with the horizontal conveying channel 3, and the surface of the channel baffle 112 can completely block the horizontal conveying channel 3.

[0032] A viewing window 8 is provided on the upper section of the vertical conveyor channel 2. The viewing window 8 includes a transparent cover plate perpendicular to the conveyor channel, allowing the operator to observe the interior of the vertical conveyor channel 2. One end of the transparent cover plate is hinged to the vertical conveyor channel 2, and the other end is equipped with a latch to fasten it onto the vertical conveyor channel 2. A mounting frame 9 is installed on the vertical conveyor channel 2, and a photoelectric detection device 7 is installed on the mounting frame 9. It detects the interior of the channel through the transparent cover plate to monitor the conveying conditions inside the channel. An audible and visual alarm device 10 is also provided, connected to the photoelectric detection device 7. The cigarette packs conveyed by the conveyor belt 1 enter the vertical conveyor channel 2. Air is ejected through the first air jet 4 to power the vertically upward conveying of the cigarette packs. After the cigarette packs reach the horizontal conveyor channel 3, air is ejected through the second air jet 5 to power the horizontally conveying of the cigarette packs. The photoelectric detection device 7 detects the interior of the channel through the transparent cover plate of the viewing window 8. If there is congestion, the audible and visual alarm device 10 will sound an alarm. The negative pressure suction port 6 draws in the vertically upward conveyed smoke packs through negative pressure. When the smoke packs pass through the valve chamber 111, they break through the channel baffle 112 and are conveyed away. When the smoke packs do not pass through, the channel baffle 112 naturally moves downward, and its surface blocks the horizontal conveying channel 3, so the negative pressure suction port 6 works normally.
