Description

Technical Field

[0001] The utility model relates to the technical field of cigarette filter rod research, in particular to the technical field of monitoring the position of capsules in capsule filter rods and detecting abnormalities such as breakage and loss.

Background Art

[0002] Spice capsules finally enter the production process of capsule cigarettes in the form of capsule filter rods. However, during the production, processing, packaging, and transportation of capsule filter rods, the capsules inside are extremely prone to unqualified situations such as position deviation, loss, and breakage, which will affect the quality of capsule cigarettes. Therefore, it is necessary to conduct quality inspection on capsule filter rods. Since the capsules are wrapped inside the filter rods, traditional optical methods cannot be used for detection. Currently, the quality inspection of capsule filter rods mainly relies on manual visual inspection, with low detection efficiency and the detection results being easily affected by human factors. An instrument for detecting the characteristics of capsules in filter rods establishes a wave peak shape position analysis algorithm to quickly detect three situations of capsule loss, position deviation, and breakage in capsule filter rods, aiming to provide a fast and effective method for the quality inspection of capsule filter rods and improve the detection efficiency, accuracy, and method adaptability of capsule filter rods.

Detailed implementation manner

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and do not limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0020] In the description of the present utility model, it should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0021] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present utility model is customarily placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined. The meaning of "several" is one or more, unless otherwise specifically defined.

[0022] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "install", "connect", "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] Referring to Figure 1-6 , the present utility model provides a detector for detecting the characteristics of capsules in filter rods, which includes a sample feeding unit 1, a sample pushing unit 2 located directly below the sample feeding unit 1, a sample detecting unit 3 arranged at the rear end of the sample pushing unit 2 and cooperating with it, and a sample sorting and collecting unit 4; the sample feeding unit includes a hopper 11 and a runner 12, and the output end of the sample feeding unit 1 is arranged towards one end of the sample track 13; the sample detecting unit includes a sample track 13 for transporting samples, a sample pusher 21 for pushing the samples to move horizontally along the sample track 13, a lead screw 23 for driving the sample pusher to move horizontally, and a first driving motor 22, and a sample detecting unit 3 is arranged on the upper side at the other end of the sample track; the sample detecting unit 3 uses a resonant cavity microwave sensor, and the sample detecting unit 3 includes a detection channel coaxial with the sample track 13; the sample sorting and collecting unit 4 includes a sorting device 41 and a sample collection box 42.

[0024] Specifically, referring to Figure 2-4, a runner 12 is provided between the hopper 11 and the sample track 13. The runner 12 is horizontally arranged, and a number of receiving grooves 121 adapted to the samples are provided on the outer wall of the runner 12. One end of the runner 12 is provided with a wheel drive motor for driving its rotation. The lower end of the hopper 11 is provided with a wheel cavity 111 adapted to the runner 12. The upper end of the wheel cavity 111 is communicated with the hopper 11, and the lower end is communicated with the sample track 13. When the receiving groove 121 of the runner 12 rotates to the position of the hopper 11, the sample automatically falls into the receiving groove 131. When the receiving groove 121 rotates to the upper side of the sample track 13, the sample inside automatically falls onto the sample track 13 under the action of gravity.

[0025] Specifically, referring to Figure 2 , the sample pusher 21 is designed as an inverted L shape. The short side of the sample pusher 21 is placed in the sample track 13, and the long side of the sample pusher 21 is fixed on the lead screw 23. The short side of the sample pusher 21 is designed as a cylinder to facilitate the smooth pushing of the sample. The first drive motor 22 is a servo motor, which can provide more stable and high-precision pushing service. The first drive motor 22 and the lead screw 23 drive the sample pusher 21 to perform a linear motion in the sample track 13.

[0026] Specifically, the sample detection unit 3 adopts a resonant cavity microwave sensor. The sample detection device 3 includes a detection channel coaxial with the sample track 13, which is convenient for the sample to pass horizontally through the resonant cavity microwave sensor. This resonant cavity microwave sensor is based on the principle of resonant cavity microwave detection. When the sample passes through the microwave resonant cavity, it will cause a shift in the microwave frequency. Measuring the frequency shift can analyze whether there are any abnormalities such as damage and missing of the sample capsule. And because the microwave measurement method is a global scan, it can accurately measure every 0.1 mm, with high precision.

[0027] Specifically, referring to 5-6, the sorting device 41 includes a second drive motor 411 and a sorting track 412. The second drive motor 411 is a stepping motor, which is used to drive the sorting track 412 to perform a clockwise or counterclockwise rotation motion. A partition 421 is arranged in the middle of the sample collection box 42. The partition 421 divides the sample collection box 42 into two grids to collect qualified products and unqualified products respectively. The partition 421 is placed directly below the sorting guide rail 412 and is in the same plane as the axis center of the sorting guide rail 412.

[0028] The working process of the present utility model:

[0029] During the operation of a detector for detecting the characteristics of capsules in a filter rod, the sample pusher 21 is located at one end far from the sample detection unit 3 under normal conditions. The experimenter arranges the samples in the hopper 11 of the feeding unit 1. When the rotating wheel 12 rotates for transportation, the samples in the hopper 11 are sent into the sample track 13. The laser sensor detects that a sample has fallen into the sample track 13. The sample pusher 21 stably pushes the sample in the sample track 13 past the sample detection unit 3. The detected sample stops on the sorting track 412. The qualified and unqualified products are distinguished through a program (this program is implemented by the PLC). The second driving motor 411 drives the sorting guide rail 412 to rotate clockwise or counterclockwise to collect the samples into the corresponding collection boxes. After the sorting guide rail rotates 360 degrees, it returns to the origin position to perform the sampling, transportation, and detection of the next section of samples.

[0030] The standard parts used in this application document can all be purchased from the market. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The electric slide rail slider, cylinder, welding machine, electric telescopic rod, and internal components of the controller all adopt conventional models in the prior art, and their internal structures belong to the prior art structures. Workers can complete the normal operation of them according to the prior art manual. Coupled with the circuit connection adopting the conventional connection method in the prior art, no specific description will be made here.

[0031] It should be noted that although the above embodiments have been described in this article, the patent protection scope of the present utility model is not limited thereby. Therefore, based on the innovative concept of the present utility model, the changes and modifications made to the embodiments described in this article, or the equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present utility model.
