Abstract

The present invention discloses an online pressing device for cigarette label paper, comprising an air blowing bracket, an air blowing mechanism, a brush bracket, a brush, and a photoelectric switch. The air blowing bracket, the brush bracket, and the photoelectric switch are mounted on the side wall of a conveyor line, with the photoelectric switch at the front, the air blowing bracket in the middle, and the brush bracket at the rear. The air blowing mechanism is mounted on the air blowing bracket, and the brush bracket is mounted on the brush. When a labeled cigarette is conveyed, the photoelectric switch is first triggered, and the air blowing mechanism immediately starts working. At the same time, the cigarette continues to move and reaches the air blowing mechanism, which blows air toward the label position. The present invention uses the combined action of compressed air and a brush to combine air blowing and brush pressing, and is applicable to both soft-pack and hard-pack cigarettes, ensuring that cigarette labels are firmly and stably adhered, solving subsequent problems caused by loose label paper adhesion, improving the success rate of cigarette storage, and providing a guarantee for tracking cigarette product information.

Description

Technical Field

[0001] The invention relates to a packaging box label pasting device, in particular to an online pressing device for cigarette label paper. Background Art

[0002] In the current tobacco industry's case-sealing process, after a box is filled with cigarettes, a No. 1 engineering code label is affixed to the lower right corner. However, labeling performance varies between different units, and sometimes the labels are loosely adhered. Adjusting the labeling machine hasn't been sufficient to improve this, necessitating a more secure labeling system on the conveyor line. A common approach is to install a rolling brush on the conveyor line, positioned above the labeling area. This brush presses down loosely adhered labels as the box passes through.

[0003] Because the brush height is fixed, while the degree of label tilt varies, if the brush is positioned too high, the label on the cigarette unit will not be pressed tightly. If the brush is positioned too low, the label will not be pressed tightly after passing through the brush, but will be carried by the brush and folded. Furthermore, the sizes of soft and hard packaging cigarettes vary, and a fixed brush height cannot simultaneously apply the label pressing function to soft and hard packaging. A loosely attached or folded label will not only make it impossible for the finished product warehouse to identify the cigarette unit, affecting its storage, but also cause information loss and affect product quality tracking. Summary of the Invention

[0004] In order to solve the problems existing in the background technology, the present invention proposes an online pressing device for cigarette label paper, which presses the label on the cigarette piece through the combined action of pressurized air and a brush during the cigarette piece conveying process to ensure that the label is firmly attached.

[0005] The technical solution of the present invention is:

[0006] An online pressing device for cigarette label paper includes an air blowing bracket, an air blowing mechanism, a brush bracket, a brush, and a photoelectric switch. The air blowing bracket, brush bracket, and photoelectric switch are mounted on the side wall of a conveyor line, with the photoelectric switch at the front, the air blowing bracket in the middle, and the brush bracket at the rear. The air blowing mechanism is mounted on the air blowing bracket, and the brush bracket is mounted on the brush. The position and angle of the air blowing mechanism are adjustable. When a rectangular label is attached to a cigarette and conveyed along the conveyor line, the photoelectric switch is first triggered, generating a signal indicating that the cigarette has arrived. The air blowing mechanism then begins to operate. Simultaneously, the cigarette continues to move and reaches the air blowing mechanism, which then blows air toward the label.

[0007] Furthermore, the blowing bracket is provided with four holes and is mounted on the side of the conveying line 6 by screws, and the height of the bracket can be adjusted by the screws.

[0008] Furthermore, the blowing mechanism is provided with one air inlet hole and one or two rows of air outlet holes to provide a channel for compressed air. The blowing mechanism 2 is fixed to the blowing bracket 1 by screws, and the installation position and angle are adjustable.

[0009] Furthermore, the brush holder is provided with 4 holes and is mounted on the side of the conveyor line by screws; a waist hole is provided above the holder, and the height of the brush is adjusted through the waist hole.

[0010] Furthermore, the blowing bracket includes a vertical support bracket, a horizontal arm located at the upper end of the vertical support bracket and rotatably connected to the vertical support bracket in the same direction as the conveying direction, and a horizontal support rod movably connected to the horizontal arm perpendicular to the conveying direction.

[0011] Furthermore, the blowing mechanism includes two mutually perpendicular arms, which are L-shaped as a whole; its connecting hole is located at the end of one arm, and its air inlet is located at the other end of the arm; its air outlet is located in the other arm, and is composed of several small holes arranged in a straight line; the air inlet and the air outlet are connected through the air pipe located in the two arms; the connecting hole of the blowing mechanism is installed on the horizontal support rod of the blowing bracket, fixed by screws, and the installation angle is adjustable.

[0012] Furthermore, the arrangement direction of the small holes is perpendicular to the conveying direction of the conveyor line. The arrangement direction of the small holes is parallel to the side of the label that first contacts the brush. The two rows of small holes are respectively aimed at the front and rear ends of the label, and the high-pressure gas is blown out simultaneously.

[0013] Furthermore, the blowing mechanism is provided with two exhaust holes. When the smoke piece passes under the blowing mechanism, one exhaust hole is aligned with the front end of the label and the other exhaust hole is aligned with the rear end of the label, and air is blown simultaneously. The two exhaust holes are arranged in parallel on two surfaces of the support arm.

[0014] Furthermore, the photoelectric switch is a diffuse reflection photoelectric switch.

[0015] The beneficial effects of the present invention are:

[0016] This invention addresses the problem of loosely adhered cigarette labels in actual production. By combining compressed air and a brush, this method combines air-blowing and brush-pressing, and is applicable to both soft and hard pack cigarettes. This ensures secure and stable adherence of cigarette labels, resolving subsequent issues caused by loosely adhered labels, improving the success rate of cigarette warehousing, and ensuring product information tracking for cigarettes.

DETAILED DESCRIPTION

[0025] Example 1

[0026] like Figure 1 As shown, the device for pressing cigarette label paper online includes an air blower 1, an air blower mechanism 2, a brush holder 3, a brush 4, and a photoelectric switch 5. The air blower 1, brush holder 3, and photoelectric switch 5 are mounted on the side wall of a conveyor line 6, with the photoelectric switch 5 at the front, the air blower 1 in the middle, and the brush holder 4 at the rear. The air blower mechanism 2 is mounted on the air blower 1, and the brush 3 is mounted on the brush holder 4. The position and angle of the air blower mechanism 2 are adjustable. A rectangular label 8 is attached to a cigarette piece 7 and conveyed along the conveyor line 6. The photoelectric switch 5 is first triggered, generating a signal indicating that the cigarette piece 7 has arrived. The air blower mechanism 2 then begins operating. Simultaneously, the cigarette piece 7 continues to move and reaches the air blower mechanism 2, which then blows air toward the label 8.

[0027] like Figure 2 As shown, the blowing bracket 1 includes a vertical support bracket 11, a horizontal arm 12 located at the upper end of the vertical support bracket and rotatably connected to the vertical support bracket in the same direction as the conveying direction, and a horizontal support rod 13 movably connected to the horizontal arm perpendicular to the conveying direction.

[0028] like Figure 3As shown, the blowing mechanism 2 comprises two mutually perpendicular arms, forming an overall L-shape. Its connection hole 21 is located at the end of one arm, and its air inlet 22 is located at the other end of the arm. Its air outlet 23 is located in the other arm, consisting of two rows of air holes 23 arranged parallel to each other on opposite sides of the arm, perpendicular to the other arm. The air inlet 22 and the air outlet 23 are connected by air pipes located within the two arms. The connection hole 21 of the blowing mechanism 2 is mounted on the horizontal support rod 13 of the blowing bracket 1 and secured with screws, with an adjustable mounting angle.

[0029] The arrangement direction of the small holes is perpendicular to the conveying direction of the conveyor line. At the same time, the arrangement direction of the small holes is also parallel to the side of the label 8 that first contacts the brush 4.

[0030] The two rows of small holes are respectively aligned with the front and rear ends of the label 8, and high-pressure gas is blown out at the same time, so that no matter which end of the label 8 is tilted, it can be effectively close to the cigarette piece, and the label 8 will not tilt when pressed by the brush 3.

[0031] like Figure 6 As shown, if the front end of the label 8 is tilted, the first exhaust hole of the blowing mechanism 2 will blow the tilted part of the label 8 toward the cigarette piece 7, reducing the distance between the tilted part of the label 8 and the cigarette piece 7; the cigarette piece 7 continues to move to the brush 4, and the installation position of the brush 4 is opposite to the position of the label 8, further pressing the tilted front end part of the label 8.

[0032] like Figure 7 As shown, if the rear end of the label 8 is tilted, the second exhaust hole of the blowing mechanism 2 will blow the tilted part of the label 8 toward the cigarette piece 7, reducing the distance between the tilted part of the label 8 and the cigarette piece 7; the cigarette piece 7 continues to move to the brush 4, and the installation position of the brush 4 is opposite to the position of the label 8, further pressing the tilted rear end part of the label 8.

[0033] In the present invention, as a preference, the blowing mechanism 2 is provided with two exhaust holes. When the smoke piece 7 passes under the blowing mechanism 2, one of the exhaust holes is aligned with the front end of the label 8, and the other exhaust hole is aligned with the rear end of the label 8, and air is blown at the same time, thereby ensuring that the label 8 can be blown toward the smoke piece 7 regardless of whether the front end or the rear end is tilted, so as to achieve a better label paper reinforcement effect.

[0034] In the present invention, preferably, the photoelectric switch 5 is a diffuse reflection photoelectric switch, which has the advantages of simple structure and easy installation, and can accurately detect cigarette pieces 7 of different brands and sizes, meeting the requirements for the accuracy of the signal when the cigarette pieces 7 are delivered to the right place.

[0035] The present invention further includes a controller electrically connected to the photoelectric switch 5 and the electric valve of the blowing mechanism 2. As the cigarette piece 7, affixed with a rectangular label 8, is conveyed along the conveyor line 6, when the cigarette piece 7 triggers the photoelectric switch 5, the controller detects the cigarette piece 7's presence and, at this point, controls the electric valve of the blowing mechanism 2 to open and release high-pressure gas.

[0036] Preferably, the controller can be a commercially available intelligent controller, such as the Hongrun NHR-5100 single-loop display controller. Its logic control such as switch input and switch output does not require programming. The detection and control function can be realized by setting or adjusting the relevant parameters according to the relevant instructions of the controller.

[0037] Finally, it should be specially noted that in the description of this application, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "transverse", "longitudinal", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.
