Description

Technical Field

[0001] This invention relates to the field of cigarette packaging production technology, and in particular to a label paper skew detection device for a ZB416 cigarette packaging machine. Background Technology

[0002] After the label paper stacks are manually added to the conveyor belt, the label paper level detection device in the ZB416 packaging machine sends an action signal based on the material level, controlling the paper stack conveying device to make the paper stack enter the flipper, and then be conveyed longitudinally to the upper part of the paper silo and enter the material silo. As the label paper in the paper silo decreases during the production process, the level detection sends a signal to start the next action cycle, so that the label paper level in the paper silo is maintained within a reasonable range. The ZB416 hard pack cigarette packaging machine is one of the most advanced domestic cigarette packaging equipment, with a production capacity of 600 packs / minute, which means it is required to stably convey 600 labels per minute.

[0003] The label paper conveying system of the ZB416 hard-pack cigarette packaging machine consists of a horizontal label paper stack propulsion mechanism, a 45-degree downward channel for the label paper stack, and first, second, and third conveying drums for the label paper. Due to design considerations, the downward channel for the label paper stack has been changed from the vertical downward channel of the previous ZB45 packaging machine to a 45-degree downward conveying channel. During the conveying process in this channel, the label paper may occasionally become skewed due to uneven force on the upper and lower sides. Skewed label paper may cause serious equipment failures such as paper jams and damage to the first conveying drum when it enters the first conveying drum.

[0004] CN104512584A discloses a label paper conveying structure for a cigarette box packaging machine, comprising two parallel synchronous toothed belts. Multiple conveying blocks are equidistantly fixed on the synchronous toothed belts, arranged along the direction of movement of the synchronous toothed belts. Each conveying block includes a conveying block body and a working layer. The conveying block body has two working surfaces perpendicular to the direction of movement of the synchronous toothed belts and in contact with the label paper. The working layer is made of wear-resistant material and fixed to the working surfaces. The conveying block body is made of engineering plastic, and the working layer is a stainless steel plate. The stainless steel plate is detachably connected to the conveying block body by multiple bolts. The multiple bolts are countersunk bolts, and adhesive is applied to the outer circumference of the countersunk bolts to fill the gap between the countersunk bolts and the stainless steel plate. The conveying block is modified from a discarded conveying block.

[0005] A pressure-adjustable label paper conveying device, disclosed in CN114287660A, includes a support plate, a bracket, and a driven wheel support. One side of the support plate and one side of the bracket are fixed by a hinge. The driven wheel support is fixed to the top of the bracket. The other side of the support plate and one side of the driven wheel support are fixed by a latch. A first upper guide plate and a drive shaft are mounted on the support plate. Two drive wheels are provided on the drive shaft. A second upper guide plate and two adjustable driven wheel devices are mounted on the driven wheel support. The two adjustable driven wheel devices are symmetrically arranged.

[0006] The adjustable driven wheel device consists of a driven wheel support arm shaft, a torsion spring, a driven wheel support arm, and a driven wheel. One end of the driven wheel support arm shaft is rotatably inserted into the inner side wall of the driven wheel support, and the other end is fixed to the middle inner wall of the driven wheel support by a support block. Both devices are designed to prevent label paper tilting warnings; otherwise, they fail to alert workers when the label paper tilts, potentially leading to damage from compression.

[0061] Figure 3This is a schematic diagram of the detection structure of a label paper skew detection device and method embodiment of the ZB416 hard-pack cigarette packaging machine according to the present invention. As shown in the figure, each detection structure includes two detection wheels 9, which are set in the corresponding mounting openings on the top plate 2 or the bottom plate 1. Each detection wheel 9 is mounted on the bottom plate 1 via a lever 10. Each lever 10 has a slot 11 at one end corresponding to the detection wheel 9. The rotating shaft of each detection wheel 9 is mounted in the corresponding slot 11 via a bearing. Each lever 10 has a support rod 14 installed in the middle.

[0065] The cigarette box label is placed between the upper base plate 1 and the lower base plate 1. By installing the device at a 45° angle, the cigarette box label moves forward under its own weight. When the cigarette box label moves to below the detection wheel 9, the force of the cigarette box label pushes the detection wheel 9 to a position flush with the installation opening 7. When the cigarette box label moves laterally, an opening appears below the detection wheel 9, which reduces the stroke between the end of the lever 10 and the sensor 16. At the same time, the limiting bolt also limits the stroke between the end of the lever 10 and the sensor 16 to prevent excessive stroke.
