Description

Technical Field

[0001] The utility model relates to the field of cigarette manufacturing, in particular to an outlet cigarette box anti-collision system of a box sealing machine. Background Art

[0002] At present, the automated production process in the industry is mainly that cigarette products are rolled and packaged by cigarette rolling machines and packaging machines, and then they are delivered to the carton sealing machine through the cigarette conveying channel and cigarette collecting machine for packaging. After being packaged into boxes, they flow into the warehouse through the cigarette box conveying channel production line (referred to as the conveying channel line). Among them, after the carton sealing machine completes the packaging of the cigarette cartons, the conveying channel after the carton sealing machine pastes the QR code, and then transports the cigarette boxes to the conveying channel line at a 90-degree angle with the carton sealing machine to flow into the warehouse.

[0003] However, since multiple carton sealers (for example, four) are arranged in parallel, the cigarette boxes sealed by them are all transported to the warehouse through the same conveyor channel line, which makes the cigarette boxes sealed by the front carton sealer often collide with the cigarette boxes sealed by the rear carton sealer at the exit of the carton sealer during transportation, and then the cigarette boxes on the conveyor channel line are pressed against the guide rails of the conveyor channel line by the cigarette boxes at the exit of the carton sealer. This phenomenon makes it difficult for the cigarette boxes on the conveyor channel line to move with the conveyor chain plate of the conveyor channel, causing the cigarette boxes to be stranded on the conveyor chain plate of the conveyor channel line at the exit of the carton sealer and unable to be transported in time. If this problem cannot be solved in time, it will cause more and more cigarette boxes on the conveyor channel line, which will cause the conveyor chain plate of the conveyor channel line to overload and stop, or the carton sealer to stop due to failure.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings, in which:

[0015] Figure 1 A schematic diagram of an outlet cigarette box anti-collision system for a box sealing machine provided in an embodiment of the utility model. DETAILED DESCRIPTION

[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0017] The utility model proposes an embodiment of an anti-collision system for cigarette boxes at the outlet of a sealing machine. Specifically, Figure 1 As shown, it includes: a conveying motor 11 of a cigarette box conveying device 10 at the outlet of the carton sealing machine, which is used to convey the cigarette boxes packaged by the carton sealing machine from the outlet to the conveying channel line 100, and then directly convey them to the warehouse by the conveying channel line 100, wherein, relative to the conveying direction of the cigarette boxes (the direction of the arrow in the figure), a first photoelectric switch B1 is provided at the conveying front side of the conveying channel line (cigarette box conveying channel production line) 100 corresponding to the outlet of each carton sealing machine, which is used to detect whether there is a cigarette box on the conveying channel line 100 at the outlet of the corresponding carton sealing machine; and a second photoelectric switch B2 is provided at the outlet of each carton sealing machine, which is used to detect whether there is a cigarette box on the cigarette box conveying device 10;

[0018] The detection signals of the first photoelectric switch B1 and the second photoelectric switch B2 are associated with the electrical signal of the conveying motor 11 .

[0019] To elaborate, in some preferred embodiments, a first reflective plate B11 may be further provided at the diagonal position of the first photoelectric switch B1 (it can be understood that the first photoelectric switch B1 is located at the conveying rear side of the conveying channel line 100 relative to the first photoelectric switch B1), and a rectangular detection area is formed by the first photoelectric switch B1 and the first reflective plate B11.

[0020] Based on this conception, a second reflective plate B22 is provided at a position linearly opposite to the second photoelectric switch B2.

[0021] Therefore, based on the above preferred embodiment, it can be understood that the first photoelectric switch B1 and the second photoelectric switch B2 are both long-distance reflective photoelectric sensors, and by respectively setting up their own reflective plates, the detection ranges such as the sensing area and sensing distance can be adaptively adjusted according to actual conditions. For example, the effective detection distance can be set to 5m.

[0022] Regarding the aforementioned electrical signal association method, the detection signals of the first photoelectric switch B1 and the second photoelectric switch B2 can be connected to the original machine PLC (cigarette box conveying channel line electronic control device), and the original machine PLC is connected to the contactor of the conveying motor 11.

[0023] Finally, the working mode of the utility model is schematically introduced: the feedback signals of B1 and B2 are both high level, indicating that there are cigarette boxes from the conveying channel line 100 ready to pass through the carton sealing machine outlet, and there are also cigarette boxes to be delivered on the cigarette box conveying device 10 at the carton sealing machine outlet. At this time, the cigarette boxes delivered by the carton sealing machine can be considered to be temporarily stored on the cigarette box conveying device 10 at the carton sealing machine outlet, so as to avoid collision and interference with the cigarette boxes passing on the conveying channel line 100, which would cause abnormal shutdown of the equipment. The way of temporarily storing in the cigarette box conveying device 10 can be understood that the conveying motor 11 can be triggered to stop running by an electrical signal. Afterwards, as production continues, after the cigarette box on the conveying channel line 100 has completely passed the carton sealing machine outlet (B1 low-level feedback), the carton sealing machine outlet can be allowed to continue to deliver cigarette boxes to the conveying channel line 100. Similarly, mature electrical control methods can be used to trigger the conveying motor 11 to run with electrical signals. This avoids the collision between the cigarette boxes conveyed from the carton sealing machine outlet and the cigarette boxes on the conveying channel line 100, which would lead to abnormal shutdown of the equipment.

[0024] In summary, the main design concept of the utility model is that it mainly includes a conveying motor of a cigarette box conveying device at the outlet of a carton sealing machine, wherein, relative to the conveying direction of the cigarette box, a first photoelectric switch is provided at the conveying front side of the conveying channel line corresponding to the outlet of each carton sealing machine, which is used to detect the cigarette boxes on the conveying channel line at the outlet of the corresponding carton sealing machine; and a second photoelectric switch is provided at the outlet of each carton sealing machine, which is used for the cigarette boxes on the cigarette box conveying device, and the detection signals of the first photoelectric switch and the second photoelectric switch are associated with the electrical signals of the conveying motor. The utility model can ensure the reliability of the operation of the production line of the cigarette box conveying channel, avoid a series of problems such as the collision between the cigarette boxes sent into the production line after packaging and the passing cigarette boxes, resulting in detention, thereby ensuring the normal operation of the cigarette box conveying equipment and the entire production process.
