Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette processing equipment and relates to a cigarette package tray blowing device. Background Art

[0002] Currently, the cigarette industry widely uses high-bay warehouse systems for the storage and transportation of tobacco strips. The workflow of a high-bay warehouse for tobacco strips is to automatically store incoming tobacco strips and automatically remove them from the warehouse and deliver them to the tobacco production line. Wooden pallets are used as carriers for transporting tobacco strips.

[0003] High-bay tobacco warehouses are used to store raw materials for the tobacco-making workshops of tobacco factories. During on-site inspections, the workshops frequently discover tobacco dust on the cigarette pack pallets. During pallet transport, the high-bay warehouse stacker cranes can obstruct detection photoelectric sensors due to the tobacco dust, causing machine downtime. Furthermore, the prolonged presence of tobacco dust poses a risk of breeding tobacco insects. To address this issue, the current solution is to remove the pallets from the cigarette packs and perform offline purge cleaning. This cleaning method is time-consuming and overlaps with the incoming cigarette packs, posing a safety hazard.

[0004] Therefore, there is an urgent need for a cigarette package tray purging device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a cigarette pack tray blowing device that can solve the technical problems of the prior art in which the trays separated from the cigarette packs are transferred out of the storage area and the cleaning operation is performed by offline blowing, which results in a long cleaning time and cross-operation with the storage of cigarette packs, thus creating safety hazards.

[0036] A tray 7 for carrying cigarette packets, a separating mechanism for separating the cigarette packets from the tray 7, a roller conveyor 1 connected to the separating mechanism for conveying the tray 7, a first blowing mechanism 2 mounted on a crossbeam of the roller conveyor 1 and acting on the tray 7, frames 44 distributed on both sides of the roller conveyor 1, a second blowing mechanism 4 integrated on the frames 44 and acting on the tray 7, an air supply mechanism for supplying air to the first blowing mechanism 2 and the second blowing mechanism 4, and a return mechanism 3 for adjusting the position of the tray 7;

[0037] It also includes a photoelectric tube 6 installed on the roller conveyor 1, a PLC controller connected to the photoelectric tube 6, an air distribution box 5 controlled by the PLC controller, and a first blowing mechanism 2 and a second blowing mechanism 4 signal-connected to the air distribution box 5.

[0038] In this embodiment, the separation mechanism is an automatic cigarette pack separator, which is an existing technology actually used in cigarette factories and will not be described in detail here. In this embodiment, it only serves to separate the cigarette packs and the tray 7.

[0039] Wherein, the gas distribution box 5 includes:

[0040] A stop valve 8 for cutting off the fluid, a filter pressure reducing valve 9 for removing impurities, and a solenoid valve 10 for controlling the opening and closing of the first blowing mechanism 2 and the second blowing mechanism 4. The solenoid valve 10 is a two-position three-way valve;

[0041] It should be noted that the PLC controller mentioned in this embodiment controls the gas distribution box 5 according to the electrical signal transmitted by the photoelectric tube 6, and further controls the opening and closing of the first blowing mechanism 2 and the second blowing mechanism 4, which belongs to the existing technology. The PLC controller here only involves the basic control opening and closing function without other limitations.

[0042] Wherein, the first blowing mechanism 2 includes:

[0043] A first fixed cavity 21 connected to the crossbeam, a first compressed air connector 22 integrated at the inlet of the first fixed cavity 21, a first extension cavity 23 connected to the first fixed cavity 21, and a first nozzle 24 integrated at the air outlet of the first extension cavity 23;

[0044] The air inlet end of the first extension cavity 23 extends to the inside of the first fixed cavity 21 , and the first nozzle 24 is used to blow away the dust accumulated on the lower surface of the tray 7 and the inner side of the base.

[0045] Wherein, the second blowing mechanism 4 includes:

[0046] A second fixed chamber 41 connected to the frame 44, a second compressed air connector 43 integrated at the inlet of the second fixed chamber 41, and a second nozzle 42 installed on the second fixed chamber 41; the second fixed chamber 41 of the second blowing mechanism 4 is connected to the frame 44 via an L-shaped angle iron bracket;

[0047] The second nozzle 42 is used to blow away dust accumulated on the upper surface of the tray 7 .

[0048] Specifically, the return mechanism 3 includes a support frame 31 connected to the roller conveyor 1, a return wheel 33, and a fastener for connecting the support frame 31 and the return wheel 33;

[0049] The fastener includes a screw 32 passing through the support frame 31 and the return wheel 33, a nut 36 threadedly connected to the screw 32, a gasket 35 fitted with the nut 36, and a distance ring 34 fitted with the gasket 35. The upper plane of the support frame 31 is provided with a movable groove (not shown in the figure), the groove width of the movable groove is greater than the diameter of the screw 32, that is, the screw 32 and the return wheel 33 can both move through the movable groove, thereby adjusting the distance between the return wheel 33 and the edge of the cigarette pack tray 7 according to actual operating conditions. Example 2:

[0050] This embodiment is further designed based on the first embodiment, has the functional modules and beneficial effects of the first embodiment, and further includes:

[0051] In this embodiment, the first nozzles 24 include at least two groups, acting on the left and right sides of the tray 7. The first nozzles 24 are connected to the first extension cavity 23 through a cross-shaped four-way pipe. The first nozzles 24 have at least three jet directions. Figure 2 There are three directions: a, b and c.

[0052] In this embodiment, the second nozzles 42 include at least five groups, and the angle between the extension line of the air inlet direction of the second nozzles 42 and the plane where the frame 44 is located is an acute angle. The second nozzles 42 are cylindrical, and the air outlet of the second nozzles 42 is arranged on the curved side thereof. The jetting direction of the second nozzles 42 (not shown in the figure) is perpendicular to the air inlet direction of the second nozzles 42, so that the compressed air ejected from the upper blowing mechanism is blown in the opposite direction of the movement of the cigarette pack tray 7, preventing the blown dust from flying everywhere and facilitating collection.

[0053] Working Principle: After the cigarette packs leaving the warehouse pass through the automatic cigarette pack separator, they are separated from the pallet 7, and the pallet 7 enters the roller conveyor 1. At this time, the position of the pallet 7 entering the roller conveyor 1 can be adjusted according to the correction mechanism 3 so that it is in the center during operation. When the roller conveyor 1 starts to operate, that is, when the pallet 7 is running on the roller conveyor 1, the PLC controller controls the solenoid valve 10 to open the first blowing mechanism 2 and the second blowing mechanism 4. The first blowing mechanism 2 is used to blow away the dust accumulated on the lower surface of the pallet 7 and the inside of the pallet 7 foot, and the second blowing mechanism 4 is used to blow away the dust accumulated on the upper surface of the pallet 7. During this process, the pallet 7 continues to run on the roller conveyor 1. When the original photoelectric tube 6 at the exit end of the roller conveyor 1 detects the pallet 7, the PLC controller controls the solenoid valve 10 to close, and the first blowing mechanism 2 and the second blowing mechanism 4 stop blowing, and the cycle repeats over and over again.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
