Description

Technical Field

[0001] This application relates to the field of cigarette production technology, and in particular to a device for detecting the opening of the side ears of a small pack. Background Technology

[0002] In the cigarette manufacturing process, packaging machines are used to package cigarettes. First, the processed cigarettes are packaged into boxes, then the boxes are packaged into cartons, and finally the cartons are packaged into boxes. During the packaging process, the small boxes and groups of cigarettes are transported to designated locations for boxing. The small boxes are transported in a small box channel. In actual production, it was found that when there are defective small boxes with open side ears, they are prone to getting stuck in the small box channel due to the outward expansion of the side ears. With the equipment running continuously, this can cause serious blockage of the small box channel, requiring subsequent cleaning and resulting in a large waste of small boxes. Utility Model Content

[0003] The purpose of this application is to provide a small box side ear opening detection device, which can effectively monitor the opening of the side ear of the packaging box and control the equipment to stop through the controller, thereby effectively solving the shortcomings of the prior art.

[0004] Therefore, this application provides a small box side ear opening detection device, including two detection components located on both sides of the small box channel, the detection components including:

[0005] The blocking component is at least partially elastically deformable;

[0006] A detection switch is disposed near the blocking member, and the detection switch corresponds to the elastically deformable portion of the blocking member to detect the generated deformation;

[0007] The controller is electrically connected to the detection switch;

[0008] The gap between the blocking components of the two detection components allows qualified packaging boxes to pass through, and the open side ears of the packaging boxes can touch the elastically deformable part of the blocking components.

[0009] In some possible implementations, the detection component further includes a guide with a guide surface. Along the conveying direction of the packaging box, the upstream side of the guide surface is higher than the packaging box, the downstream side of the guide surface is lower than the packaging box, and the blocking element is located within the extension area of ​​the guide surface.

[0010] In some possible implementations, the guide surfaces of the two detection components are positioned opposite each other.

[0011] In some possible implementations, the distance between the guide surfaces of the two detection components is no greater than the minimum distance between the guides of the two detection components.

[0012] In some possible implementations, the distance between the guide surfaces of the two detection components is equal to the minimum distance between the guides of the two detection components.

[0013] In some possible implementations, the guide is a vertically arranged plate-like structure, with the guides of the two detection components arranged opposite to each other and parallel to each other. The gap between the two guides allows qualified packaging boxes to pass through, and the guide surface is located on the upstream side edge of the guide.

[0014] In some possible implementations, the guide surface is arranged in a concave arc shape.

[0015] In some possible implementations, at least a portion of the blocking member can elastically deform along the conveying direction of the packaging box, and the detection switch is located upstream or downstream of the blocking member along the conveying direction of the packaging box.

[0016] In some possible implementations, the detection assembly further includes a support frame, and the blocking member is an elongated member with one end connected to the support frame and the other end of the blocking member elastically deforming and swinging relative to the end of the blocking member connected to the support frame.

[0017] In some possible implementations, the blocking member is a long plate-shaped structure with one side of the blocking member facing the detection switch in the thickness direction.

[0018] The small box side ear opening detection device provided in the embodiments of this application includes two detection components. The detection components are provided with a blocking member, a detection switch and a controller. The blocking member can at least partially deform, and the detection switch can detect the deformation of the blocking member and send a signal to the controller. Qualified packaging boxes can pass smoothly through the small box channel. When a packaging box with an open side ear passes by, the open side ear causes the blocking member to deform, thereby triggering the detection switch. The controller receives the signal and can effectively detect defective boxes so as to stop the machine and prevent serious blockage of packaging boxes. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figures 1-3 As shown in the illustration, this application provides a device for detecting the open side ears of cigarette packs, applied in the packaging process of cigarette factories. During the packaging process, cigarette packing machines are used to package cigarettes. In the process of packaging cigarettes into boxes, the small packaging boxes and cigarettes are transported to designated locations for further packaging. The small packaging boxes are transported through a small box channel. Qualified small packaging boxes have a neat and defect-free appearance. However, in reality, there are defective small packaging boxes with open side ears. When these defective small packaging boxes are transported through the small box channel, they become stuck. If the equipment continues to run, it will cause severe blockage in the small box channel, requiring a long downtime for unblocking and resulting in a large waste of packaging boxes. The device for detecting the open side ears of cigarette packs provided in this application aims to detect defective small boxes with open side ears, promptly identify defective small boxes, and allow for timely human intervention to stop the machine, preventing severe blockage and avoiding a large waste of small boxes.

[0024] The small box side ear opening detection device includes two detection components 100, which are located on both sides of the small box channel. A qualified small box can pass smoothly through the gap space between the two detection components 100. When the side ear of the small box is open, the detection component 100 can detect that the side ear of the small box is open because the side ear is expanded outward.

[0025] The detection component 100 includes a blocking element 101, a detection switch 102, and a controller. The blocking element 101 is at least partially capable of elastic deformation. The detection switch 102 is positioned close to the blocking element 101 and is designed to detect the elastically deformable portion of the blocking element 101. The controller is electrically connected to the detection switch 102. When elastic deformation occurs on the blocking element 101, the detection switch 102 detects the deformation and transmits a signal to the controller. The controller can be electrically connected to the control cabinet of the equipment, allowing it to transmit a stop signal to the control cabinet. The control cabinet then stops the equipment to prevent severe blockage of the small box channel. An audible and visual alarm can also be installed, which is electrically connected to the controller. After receiving the detection signal from the detection switch 102, the controller activates the audible and visual alarm, alerting relevant personnel to the presence of a defective small box. Personnel can then promptly perform a stop operation to prevent severe blockage of the small box. After clearing the defective small box, the equipment can be restored to operation.

[0026] The gap between the blocking members 101 of the two detection components 100 allows qualified packaging boxes to pass through smoothly. When the side ears of the packaging box are open, during the box conveying process, the open side ears can touch the elastically deformable part of the blocking member 101, thereby generating elastic deformation and triggering the detection switch 102.

[0027] Preferably, the detection component 100 further includes a guide 103, which is provided with a guide surface 1031. Along the conveying direction of the packaging box, the height of the upstream side of the guide surface 1031 is higher than that of the packaging box, and the height of the downstream side of the guide surface 1031 is lower than that of the packaging box. The blocking member 101 is located within the extension area of ​​the guide surface 1031. Since the opening angle of the side ears of the box may be different, the guide 103 is provided to ensure that the opening side ears can touch the blocking member 101.

[0028] In some embodiments, the guide surfaces 1031 of the two detection components 100 are arranged opposite to each other, and the distance between the guide surfaces 1031 of the two detection components 100 is not greater than the minimum distance between the guides 103 of the two detection components 100.

[0029] Preferably, the distance between the guide surfaces 1031 of the two detection components 100 is equal to the minimum distance between the guide members 103 of the two detection components 100. In one example, the guide member 103 is a vertically arranged plate structure. The guide members 103 of the two detection components 100 are arranged opposite to each other and parallel to each other. The gap between the two guide members 103 allows qualified packaging boxes to pass through. The guide surface 1031 is located on the upstream side edge of the guide member 103. The distance between the two guide surfaces 1031 is equal to the distance between the two guide members 103. In this embodiment, the guide member 103 is a plate structure. Taking the horizontal direction of the box channel as an example, the central symmetry plane is taken as a vertical plane. The left and right parts of the width direction of the box channel are symmetrical relative to the central symmetry plane. The plane and the central symmetry plane are parallel. The two guides 103 are symmetrical about the central symmetry plane. Along the conveying direction of the small box channel, the upstream edge of the guide 103 constitutes the guide surface 1031. In actual installation, the distance between the two guides 103 is equal to the width of the small box channel. The height of the upstream side of the guide surface 1031 is higher than the top height of the small box, and the height of the downstream side of the guide surface 1031 is lower than the bottom height of the small box. When the side ears of the small box are open, the small box travels to the guide 103, and the open side ears contact the guide surface 1031. The small box continues to move forward, and the guide surface 1031 will cause the side ears of the small box to gradually open at a larger angle so that the side ears can touch the blocking member 101. Along the conveying direction of the small box channel, the blocking member 101 is set in the extension area of ​​the guide surface 1031.

[0030] The guide surface 1031 is set in a concave arc shape, that is, the middle part of the guide surface 1031 is set to arch upwards more than the upstream and downstream sides, which is more conducive to the downward expansion of the opposite ear.

[0031] Preferably, at least a portion of the blocking member 101 can elastically deform along the conveying direction of the packaging box. Along the conveying direction of the packaging box, the detection switch 102 is located upstream or downstream of the blocking member 101, which is more conducive to the side ears of the moving box causing deformation of the blocking member 101.

[0032] In one example, the detection component 100 further includes a support frame 104, and a blocking member 101 is an elongated member. One end of the blocking member 101 is connected to the support frame 104, and the other end of the blocking member 101 can elastically deform and swing relative to the end of the blocking member 101 connected to the support frame 104. The blocking member 101 has a long plate-like structure, and one side of the blocking member 101 in the thickness direction faces the detection switch 102. In this embodiment, the support frame 104 is located outside the small box channel, and the blocking member 101 is further away from the small box channel relative to the guide member 103. The blocking member 101 has a long plate-like structure, and the top of the blocking member 101 is connected to the support frame 104. The bottom of the blocking member 101 extends vertically downward. The entire blocking member 101 can undergo elastic deformation, and the plane where the blocking member 101 is located is perpendicular to the plane where the guide member 103 is located. Yes, the conveying direction of the small box is perpendicular to the blocking member 101. The detection switch 102 is connected to the support frame 104. The detection switch 102 is located upstream of the blocking member 101, and there is a certain detection gap between the detection switch 102 and the blocking member 101. The detection switch 102 and the bottom part of the blocking member 101 are aligned and correspond. The detection switch 102 is preferably a proximity switch. When the open side ear of the small box touches the blocking member 101 and causes the blocking member 101 to deform, the detection gap between the detection switch 102 and the blocking member 101 increases. The detection switch 102 detects a signal, which indicates that a defective small box has appeared. The detection switch 102 transmits the signal to the controller. The controller can stop the machine through the control cabinet of the equipment or sound and light alarms. Personnel can be informed of the alarm signal in time and stop the machine in time.

[0033] In this embodiment, the spacing between the blocking member 101 and the guide member 103, as well as the spacing between the two guide members 103, can be adjusted as long as the qualified small box can pass smoothly through the two detection components 100 and the small box with its side ears open can deform the blocking member 101. In practice, the small box with different sizes of small box channels will be tested and adapted.
