Description

Technical Field

[0001] The utility model relates to the technical field of sensor installation in a wrapping workshop, and more specifically, to a probe positioning frame for detecting the existence of aluminum foil. Background Art

[0002] The ZB416 packaging machine is the mainstream domestic high-speed slim cigarette packaging equipment in my country, with a rated speed of 500 packs per minute. Each pack of cigarettes consists of 20 cigarettes, a sheet of aluminum foil, a sheet of inner frame paper, and a sheet of trademark paper. The first wheel of the ZB416 rotates continuously and at high speed counterclockwise to continuously grab cigarettes; the aluminum foil conveying drum conveys the aluminum foil from top to bottom through negative pressure until the aluminum foil moves along the edge of the first wheel; the second wheel moves clockwise, and its motion trajectory is tangent to the first wheel; when the cigarette pack grabbed by the first wheel, the center of the aluminum foil, and the box mold of the second wheel are in a straight line, the push rod pushes the cigarette to the middle of the aluminum foil from right to left, so that the aluminum foil just completely wraps the cigarette and enters the second wheel completely.

[0003] When the negative pressure of the aluminum foil conveying drum is abnormal, the aluminum foil cannot be stably and correctly adsorbed, resulting in a lack of aluminum foil in the first round, or a delay in the aluminum foil conveying, so that the cigarette cannot intersect with the middle position of the aluminum foil, resulting in defective cigarette packs such as exposed cigarettes and damaged aluminum foil. In order to ensure that the cigarettes can be pushed to the middle position of the aluminum foil every time, the equipment is equipped with a round of aluminum foil existence detection, which is used to monitor whether the edge of the first round is on a piece of aluminum foil when the cigarette is about to enter the second round, and whether this piece of aluminum foil is in the correct position to ensure that the cigarette intersects with the middle position of the aluminum foil. If the detection monitoring finds that there is no aluminum foil, or the aluminum foil is in an incorrect position when the cigarette pack enters the aluminum foil, the equipment will reject the unqualified cigarette pack in the third round.

[0004] Because the first and second wheels are close to each other and rotate at high speed, and there is a push rod that reciprocates left and right between them, the first round of aluminum foil presence detection can only be installed in a small area. The detection adopts FU-66 straight-head optical fiber sensor. The optical fiber is bent in the small area, and there is scratching and squeezing between the optical fiber and the surrounding areas, which makes the optical fiber easy to be damaged and has a service life of 2-30 days. As a result, the first round of aluminum foil presence detection cannot operate normally and fails frequently. Utility Model Content

[0005] In view of the above shortcomings, the purpose of the utility model is to provide a probe positioning frame for detecting the presence of aluminum foil.

[0006] To achieve the above object, the present utility model provides a probe positioning bracket for detecting the presence of aluminum foil paper, which includes a probe mounting rod and a connecting rod bent outward at the rear end of the probe mounting rod. A probe positioning hole is provided at the front end of the probe mounting rod, and the probe positioning hole is used to position an optical fiber probe. A positioning groove communicating with the probe positioning hole is provided on the probe mounting rod, and the positioning groove is used to position the optical fiber. A pressing screw is provided on the hole wall of the probe positioning hole, and the pressing screw can press the optical fiber probe in the probe positioning hole. First mounting holes and second mounting holes are provided at both ends of the connecting rod, and are connected to an external structure through the first mounting holes and the second mounting holes.

[0007] Preferably, a fiber optic protective sleeve is provided at the connection between the optical fiber probe and the optical fiber. A plurality of uniformly arranged adjustment holes are provided on both sides of the positioning groove, and elastic pressing pieces are provided on the adjustment holes. The elastic pressing pieces are in a "zigzag" structure, and locking bolts threadedly connected to the adjustment holes are provided at both ends of the elastic pressing pieces.

[0008] Preferably, the optical fiber probe is a 90° right-angle fiber optic sensor for position detection.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The following is an explanation of the embodiments of the utility model based on its overall structure.

[0023] The specific implementation of the utility model is as follows:

[0024] As attached Figures 1 - 5As shown in the figure, a probe positioning frame for detecting the presence of aluminum foil paper includes a probe mounting rod 1 and a connecting rod 2 bent outward at the rear end of the probe mounting rod 1. A probe positioning hole 3 is provided at the front end of the probe mounting rod 1. The probe positioning hole 3 is used to position the fiber optic probe 4. A positioning groove 5 communicating with the probe positioning hole 3 is provided on the probe mounting rod 1. The positioning groove 5 is used to position the fiber optic cable. A compression screw 6 is provided on the hole wall of the probe positioning hole 3. The compression screw 6 can press the fiber optic probe 4 tightly in the probe positioning hole 3. First mounting holes 7 and second mounting holes 8 are provided at both ends of the connecting rod 2. The probe positioning frame is connected to an external structure through connection bolts 14 arranged in the first mounting holes 7 and the second mounting holes 8.

[0025] In the probe positioning frame for detecting the presence of aluminum foil paper of the present utility model, after the fiber optic probe 4 is positioned through the probe positioning hole 3, the compression screw 6 is used to press the fiber optic probe 4 tightly to prevent the fiber optic probe 4 from loosening. The fiber optic cable of the fiber optic probe 4 is positioned through the positioning groove 5 to prevent the fiber optic cable from swinging left and right and being easily broken, avoiding affecting the transmission of optoelectronic data. The optical fiber is not easily bent, avoiding the optical fiber from being scratched and squeezed by the structure in a narrow space and causing the optical fiber to be easily damaged, ensuring the service life of the fiber optic probe 4, and avoiding the problem that the detection of the presence of a roll of aluminum foil paper fails due to the failure of the fiber optic probe 4, affecting the normal operation of the production line.

[0026] The entire probe positioning frame is fixedly connected to an external device through the first mounting hole 7, the second mounting hole 8 of the connecting rod 2 and the connection bolt 14, with firm connection and convenient disassembly and assembly.

[0027] In this embodiment, a fiber optic protection sleeve is provided at the connection between the fiber optic probe 4 and the optical fiber. A plurality of uniformly arranged adjustment holes 9 are provided on both sides of the positioning groove 5. Elastic pressing pieces 10 are provided on the adjustment holes 9. The elastic pressing pieces 10 are in a "zigzag" structure. Locking bolts 11 threadedly connected to the adjustment holes 9 are provided at both ends of the elastic pressing pieces 10. The elastic pressing pieces 10 are made of metal sheet structures. The bolt heads of the locking bolts 11 squeeze the elastic pressing pieces 10 to deform them, thereby pressing the fiber optic cable in the positioning groove 5 tightly.

[0028] The pressing position of the elastic pressing piece 10 on the fiber optic cable can also be adjusted by installing the elastic pressing piece 10 at the adjustment holes 9 at different positions.

[0029] In this embodiment, the fiber optic probe 4 is a 90° right-angle fiber optic sensor, and the position of the aluminum foil paper is detected by light reflection.

[0030] In this embodiment, the 90° right-angle fiber optic sensor selects the Keyence FU-66 type right-angle fiber optic sensor.

[0031] In this embodiment, an optical fiber through hole 12 penetrating through both sides is provided in the connecting rod 2, and the optical fiber cable can pass through the optical fiber through hole 12 for positioning, preventing the optical fiber cable from swinging and colliding with the surrounding structures.

[0032] In this embodiment, a slit 13 is formed at one end of the connecting rod 2 away from the probe mounting rod 1, and the slit 13 extends to the pore wall of the optical fiber through hole 12. The connecting rod 2 and the probe mounting rod 1 are integrally formed aluminum alloy structures or stainless steel structures. By providing the slit 13 on the connecting rod 2, the structures on both sides of the slit 13 can undergo elastic deformation. After the structures on both sides of the slit 13 are opened to a certain extent, the optical fiber cable can be inserted into the optical fiber through hole 12, and then the optical fiber cable is clamped when the structures on both sides of the slit 13 return to their original positions.

[0033] In this embodiment, the first mounting hole 7 on the connecting rod 2 passes through the slit 13. When the connecting bolt 14 on the first mounting hole 7 is connected to an external structure, the structures on both sides of the slit 13 can be squeezed, reducing the size of the slit 13, thereby further clamping the optical fiber cable in the optical fiber through hole 12.

[0034] In this embodiment, the first mounting hole 7 and the second mounting hole 8 are oval holes, and the major axes of the first mounting hole 7 and the second mounting hole 8 are perpendicular to each other. By appropriately adjusting the position of the connecting rod 2, the position of the optical fiber probe 4 can be finely adjusted to meet the installation and use requirements on site.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made according to the above teachings. Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and do not limit the present invention.
