Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cigarette pack forming and packaging, in particular to a cigarette strip film deviation detection device and a cigarette strip film packaging machine. Background Art
[0002] In the cigarette production process, the cigarette film packaging machine is a device used to automatically package cigarettes in a transparent plastic film. The cigarette film packaging machine usually includes automatic conveying, cutting, packaging, positioning and other actions to efficiently and accurately complete the cigarette packaging work. The working principle of the cigarette film packaging machine is: first, the cigarette enters the packaging machine through the automatic conveying system, and then the packaging machine automatically packages the cigarette in a transparent plastic film according to preset parameters such as packaging size, film tension, etc. During the packaging process, the machine will perform cutting, folding, packaging, heat sealing and other steps to ensure the integrity and aesthetics of the packaging. The turret of the cigarette film packaging machine is one of the key components, which is usually used to carry and rotate multiple packaging stations to achieve efficient continuous packaging operations. The position of the film adsorbed on the turret is crucial to the packaging variety of the cigarette film, but in the actual production process, due to changes in negative pressure, the cleanliness of the equipment, and the position of the machine, the position of the film adsorbed on the turret will be offset or fall off. When there is an offset or fall, it is necessary to detect it in time to find and eliminate quality risks.
[0003] In order to ensure that the film can be detected in time when the position where it is adsorbed on the turret is shifted or falls off, the method in the prior art is to install two photoelectric detection devices above the turret arc at the position where the film is adsorbed for detection. When the film is adsorbed on the turret and shifts or falls off, one or both photoelectric detection devices will fail to detect the film, and the electronic control system of the cigarette film packaging machine will lose one or two 24V signals, and the cigarette film packaging machine will alarm and stop.
[0004] Since the film is transparent and will curl during adsorption, it will cause frequent false detections in photoelectric detection, causing equipment shutdown and affecting the effective operation rate of the equipment. Utility Model Content

[0020] 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.
[0021] In order to ensure that the film can be detected in time when it is offset or falls off when it is adsorbed on the turret, the method in the prior art is to install two photoelectric detection devices above the arc of the turret at the position where the film is adsorbed for detection. However, since the film is transparent and curls when it is adsorbed, it will cause frequent false detections in the photoelectric detection, causing the equipment to shut down and affecting the effective operation rate of the equipment. The utility model adds a negative pressure sensor and a three-way joint. When the turret adsorbs the film and it deviates or falls, the suction holes on the suction block are not completely blocked, and the negative pressure value detected by the negative pressure sensor will be lower than the negative pressure threshold. Then the electronic control system of the cigarette film packaging machine will lose the signal, thereby triggering an alarm shutdown. The utility model avoids the problem of frequent false detections in photoelectric detection, and the detection method is more reliable and effective, which reduces the frequency of equipment shutdowns and improves the effective operation rate of the equipment.
[0022] The utility model proposes an embodiment of a cigarette film deviation detection device, specifically, as follows Figure 1As shown, it includes a three-way connector 1 and a negative pressure sensor 2, the negative pressure sensor 2 is connected to the three-way connector 1, the three-way connector 1 is connected to one end of a negative pressure pipeline 8, the other end of the negative pressure pipeline 8 is connected to a negative pressure control disk 6, the negative pressure control disk 6 is arranged on a turret 3, a suction block 4 is arranged on the turret 3, and the negative pressure control disk 6 is connected to the suction block 4.
[0023] Specifically, the three-way connector 1 includes three interfaces, two of which are connected to the negative pressure pipeline 8, and the connection lines of the two interfaces are in the same direction as the transmission path of the negative pressure pipeline 8; the other interface is perpendicular to the transmission path of the negative pressure pipeline 8, and the interface is connected to the negative pressure sensor 2.
[0024] Furthermore, the three-way connector 1 is a positive three-way connector 1, in which the output direction of one interface is perpendicular to the connection lines of the other two interfaces. The positive three-way connector 1 can realize a flow channel with a smaller curvature radius and a smoother angle, and can effectively and evenly distribute the flow in the negative pressure pipeline 8, which helps to maintain the stability and efficiency of negative pressure transmission.
[0025] Specifically, the turret 3 includes a first turret and a second turret, wherein the first turret and the second turret are of the same shape and size, are arranged opposite to each other, and are evenly arranged with a plurality of suction blocks 4 on the surface edges of the first turret and the second turret. Specifically, six suction blocks 4 are evenly arranged on the surface edge of the first turret, and six suction blocks 4 are evenly arranged on the surface edge of the second turret, and the six suction blocks 4 on the first turret correspond to the six suction blocks 4 on the second turret in one-to-one position.

When the equipment is running and the turret 3 adsorbs the film 7, the negative pressure control disk 6 connects the negative pressure to the four suction blocks adsorbing the film 7. The suction holes of the four suction blocks are all blocked by the film, and at this time, the negative pressure detected by the negative pressure sensor is about 0.2MP.
[0027] In one embodiment of the utility model, the cigarette film deviation detection device also includes a controller, which is connected to the negative pressure sensor 2. When the negative pressure value detected by the negative pressure sensor 2 is lower than the set negative pressure threshold, the controller performs shutdown control of the cigarette film packaging machine. Specifically, under normal operation, the suction holes of the four suction blocks 4 are all blocked by the film. At this time, the negative pressure value detected by the negative pressure sensor 2 is about 0.2MP. The threshold of the negative pressure sensor 2 is set at 0.15MP. When the turret 3 adsorbs the film 7 and the film 7 deviates or falls, since the suction holes on the four suction blocks 4 are not completely blocked, the negative pressure value detected by the negative pressure sensor 2 will be lower than the set value of 0.15MP, then the electronic control system of the equipment will lack a 24V signal, and the equipment will alarm and shut down.
[0028] In one embodiment of the utility model, the cigarette film deviation detection device also includes an alarm indicator light; the alarm indicator light is electrically connected to the controller, and when the detected negative pressure value is lower than the set negative pressure threshold, the display color of the alarm indicator light changes from green to red.
