Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette packaging machines, specifically relating to a pack rejecter with status detection and a device for processing the connector of transparent paper in small boxes. Background Technology

[0002] The transparent paper for cigarette packs (or simply packs) is automatically produced by a packaging machine. During production, it is essential to splice the transparent paper. Whether spliced ​​manually or automatically, defects in the production quality of the transparent paper are easily introduced before and after splicing. Therefore, it is necessary to discard several packs before and after splicing to prevent them from flowing into subsequent processes and affecting the final product quality.

[0003] In existing packaging machines, operators sometimes forget to manually remove defective boxes when splicing linerboard, leading to defective products entering the next process and causing quality issues. Alternatively, detectors and rejecters are installed after the splicing process to remove small boxes with splicing defects. However, after prolonged operation, the rejecter may not operate completely correctly, may malfunction, or may even crush or misalign the small boxes. Therefore, it is necessary to design a rejecter with status detection and a device for handling spliced ​​linerboard joints in small boxes. Utility Model Content

[0004] The purpose of this invention is to provide a pack rejector with status detection and a small box transparent paper joint processing device to solve the defect in existing small box packaging machines that cannot detect whether the pack rejector has failed during the rejection action.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A status detection rejector includes a rejector body electrically connected to a first controller; the first controller is electrically connected to a first detector, which is disposed opposite to the rejector body, and is used to detect the positioning status of the rejector body when it performs a rejecting action, and to feed back the positioning status to the first controller; the rejector body includes a driver electrically connected to the first controller; the output shaft of the driver is fixedly connected to a rejecting frame, and a movable block is connected to the end of the rejecting frame away from the driver; the driver can be an electromagnet.

[0007] In fact, when the pack remover moves, it moves once for each pack removal. The first detector can detect whether the pack remover is in place and provide feedback. If the pack remover is not in place, the packs will be squeezed, causing a quality accident. It is difficult for people to find the squeezed packs. Therefore, this application can prevent this from happening. When this happens, it will provide timely feedback and stop the machine to remind the staff.

[0008] Further specifying, a sensing detection element is fixedly installed on the rejection rack, the sensing detection element has a sensing surface, and the sensing surface is in the direction of the detection light transmission of the first detector; wherein, when the rejection action of the rejection device body is completed, the detection light of the first detector is perpendicular to the sensing surface.

[0009] The inclusion of a sensing element can significantly improve the sensing accuracy of the first detector's light, thereby enhancing the accuracy and sensitivity of detecting the arrival status of the pack rejection device.

[0010] Further specifying, the sensing detection element includes a sensing section and a mounting section, with an angle of 120° between the sensing section and the mounting section. When the rejecting device body is in position, the sensing surface of the sensing section is perpendicular to the detection light of the first detector. This structural design ensures that the first detector has the highest detection accuracy under normal operation, and even if the device is not fully in position, the error can be judged by analyzing the detection data of the first detector, so as to facilitate flexible maintenance according to the magnitude of the error. The mounting section has a mounting hole, which is connected to the threaded hole on the rejecting frame by a screw.

[0011] Further defined, the first surface of the rejection rack is provided with a snap-fit ​​groove, and the end of the sensing detection element near the rejection rack is provided with a snap-fit ​​buckle, which snaps or inserts into the snap-fit ​​groove; the first surface of the rejection rack is the surface opposite to the first detector.

[0012] Furthermore, a detector bracket is installed below the body of the rejector, and the first detector is mounted on the detector bracket.

[0013] In this application, the detector bracket can be installed into the packaging machine, specifically on the frame below the turret, and the distance between the first detector and the rejector body can be controlled.

[0014] In practice, the first detector can be a fiber optic detector or an infrared rangefinder, etc.

[0015] Further defined, the detector bracket includes a base plate, a transition plate connected to the base plate, and a mounting plate connected to the transition plate, wherein the mounting plate is provided with detector mounting holes; the base plate and the transition plate, and the transition plate and the mounting plate are perpendicular to each other.

[0016] Secondly, this application provides a small box transparent paper splice processing device, including a turret and the aforementioned status detection rejector; the turret is provided with a rejection notch, the status detection rejector is installed below the rejection notch, and when the rejector body performs the rejection action, it makes way for the rejection notch so that the small box transported by the turret falls from the rejection notch.

[0017] During normal transfer of small boxes (or cigarette packs) in the turret, the pack remover body fills the removal gap, with the top of the pack remover body flush with the top of the removal gap, preventing the small box from falling through the removal gap; when the transparent paper of the small box is defective and needs to be removed, the pack remover body is controlled to make way for the removal gap, allowing the small box to fall through the removal gap.

[0018] Further specifying, the first controller is a PLC controller, which is connected to a control bus and receives the turret's operating data through the control bus. The turret's operating data includes at least encoder signals and splice detection signals.

[0019] The utility model adopting the above technical solution has the following advantages:

[0020] 1. The first controller can receive the preset detector signal. The preset detector is used to detect manually spliced ​​transparent paper or transparent paper with its own joints. When these joints are detected, feedback is sent to the first controller. After receiving the feedback, the first controller calculates the action timing of the rejector body according to the encoder signal and generates a rejection command. After receiving the rejection command, the rejector body moves to make way for the rejection gap, so that the defective small box falls down. It has high accuracy, simple structure and high practicality.

[0021] 2. The first detector can detect the status of the pack rejecting device. If the pack rejecting device is not fully in place, the small boxes or cigarette packs will be squeezed, causing a quality accident. The first detector can detect the squeezed cigarette packs in a timely and easy manner, preventing them from flowing into the subsequent process. When the pack rejecting device is not fully in place, the first controller can control the machine to stop based on the detection feedback of the first detector to remind the operator and avoid greater losses.

Detailed Implementation

[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description.

[0035] Example 1

[0036] like Figures 1-3 As shown, this utility model discloses a pack rejection device with status detection, including a pack rejection device body 300. The pack rejection device body 300 is electrically connected to a first controller, which is a PLC controller. The PLC controller is connected to the existing encoder and transparent paper detector of the packaging machine, and can collect signals from the manual splicing joints and self-installed splicing joints of the transparent paper, as well as encoder signals. Thus, defect detection of the transparent paper in small boxes (i.e., cigarette packs) is realized. The encoder is used to monitor the stride of the turret, and the transparent paper detector is used to monitor the joints (manual splicing joints or self-installed splicing joints) or other defects of the transparent paper. The first controller is electrically connected to a first detector, which can be a fiber optic detector. The first detector is positioned opposite to the pack rejection device body 300 and is used to detect the arrival status of the pack rejection device body 300 when it performs a pack rejection action, and feed back the arrival status to the first controller. This structural design enables timely detection and prevention of cigarette pack compression. When rejecting defective boxes, the first detector can detect whether the rejection device 300 has completed its action and provide feedback after each rejection. If the rejection device 300 has not completed its action, the first detector will promptly send the detection data to the first controller, which will then control the device to stop and issue an alarm to remind the staff.

[0037] like Figure 4 As shown, the rejector body 300 in this embodiment includes a driver, which is electrically connected to a first controller. A rejecting frame 302 is fixedly connected to the output shaft of the driver, and a movable block 301 is connected to the end of the rejecting frame 302 furthest from the driver. The driver can be a rejecting electromagnet, and the first detector is mainly a component for detecting the position of the rejecting electromagnet. In fact, a connecting hole 303 is provided at the end of the rejecting frame 302, and the output shaft of the driver is fixedly connected to the rejecting frame 302 via bolts and the connecting hole 303.

[0038] Example 2

[0039] like Figure 1 , Figure 4As shown, unlike Embodiment 1, this embodiment adds a sensing detection element 310 to improve the accuracy of detecting the arrival status of the rejector body 300. The sensing detection element 310 is fixedly installed on the rejector frame 302 in this embodiment. The sensing detection element 310 has a sensing surface 313, which is in the transmission direction of the detection light emitted by the first detector. When the rejector body 300 completes its rejecting action, the detection light from the first detector is perpendicular to the sensing surface 313. When the rejector body 300 does not complete its rejecting action, the detection light from the first detector will not be perpendicular to the sensing surface 313, resulting in a significant difference in the obtained detection results. Based on this difference, it can be inferred that the rejecting action of the rejector body 300 is not complete, and then the machine can be stopped for maintenance. Simultaneously, this configuration of the sensing detection element 310 significantly improves the sensing accuracy of the detection light from the first detector, thereby improving the accuracy and sensitivity of detecting the arrival status of the rejector body 300.

[0040] For example, such as Figure 4 , Figure 5 As shown, the sensing detection element 310 includes a sensing section 312 and a mounting section 311. The included angle between the sensing section 312 and the mounting section 311 is 120°. When the rejecting device body 300 is in position, the sensing surface 313 of the sensing section 312 is perpendicular to the detection light of the first detector. This structural design ensures that the detection accuracy of the first detector is the highest when the device is operating normally. In case of incomplete positioning, the error can be judged by analyzing the detection data of the first detector, so as to facilitate flexible maintenance according to the magnitude of the error. The mounting section 311 is provided with a mounting hole, which is connected to the threaded hole on the rejecting frame 302 by a screw.

[0041] For example, such as Figure 6 As shown, the sensing detection component 310 includes a sensing section 312 and a mounting section 311, which are integrally formed with the rejecting frame 302. The angle between the sensing section 312 and the mounting section 311 is 120°. Thus, when the rejecting device body 300 is in place, the sensing surface 313 of the sensing section 312 is perpendicular to the detection light of the first detector, which improves the detection accuracy of the first detector.

[0042] like Figure 7 As shown, the first surface of the rejection rack 302 in this embodiment is provided with a snap-fit ​​groove, wherein the first surface of the rejection rack 302 is the surface opposite to the first detector; the snap-fit ​​groove is a T-shaped groove 3021, and correspondingly, a snap-fit ​​buckle is provided at one end of the sensing detection element 310 near the rejection rack 302. The snap-fit ​​buckle is also T-shaped, and the snap-fit ​​buckle snaps into the snap-fit ​​groove. The structure is simple and the installation is convenient.

[0043] For the installation and debugging of the first detector, exemplarily, a detector bracket 320 is installed below the packer body 300, and the first detector is mounted on the detector bracket 320; wherein, as... Figure 8 As shown, the detector bracket 320 includes a base plate, a transition plate connected to the base plate, and a mounting plate connected to the transition plate. The mounting plate has detector mounting holes 321 for mounting a first detector, and the first detector is perpendicular to the mounting plate. The base plate and the transition plate, and the transition plate and the mounting plate are perpendicular to each other. This design of the detector bracket 320 allows the first detector to be installed later in the packaging machine, specifically on the frame below the turret 100. It also makes the distance between the first detector and the rejector body adjustable, resulting in better compatibility.

[0044] Example 3

[0045] like Figures 1 to 3 As shown, a small box transparent paper splice processing device includes a turret 100 and a pack rejection device with status detection. The turret 100 includes a turntable and twelve limit blocks 101 arranged in a circumferential array on the turntable. A limit opening 102 is formed between two adjacent limit blocks 101. The size of the limit opening 102 is the same as the size of the small box, i.e., the cigarette pack. The turntable is rotatably mounted on a frame 200. A transparent arc plate 201 is installed on the frame 200 around the limit opening 102. A transparent paper splice detector for detecting transparent paper can be installed on the transparent arc plate 201. A mounting bracket 203 can also be installed on the frame 200. A driver is installed in the mounting bracket 203. The driver is a rejection electromagnet. The turret 100 is provided with a rejection notch 103, and a guide chute 204 is provided below the rejection notch 103. A recycling box can be placed below the guide chute 204 to receive the rejected small boxes. A rejection device with status detection is installed below the rejection notch 103, and when the rejection device body 300 performs the rejection action, it makes way for the rejection notch 103 so that the small boxes transferred by the turret 100 fall from the rejection notch 103.

[0046] like Figure 1 As shown, a mounting hole 202 is provided on the transparent arc plate 201. A transparent paper connector detector can be installed in the mounting hole 202, such as a fiber optic mounting bracket for fixing a fiber optic amplifier, to detect defects in the transparent paper (connection, fold, wrinkle, misalignment, etc.).

[0047] When the turret 100 is normally transferring small boxes (or cigarette packs), the pack remover body 300 fills in the removal gap 103, with the top of the pack remover body 300 flush with the top of the removal gap 103, preventing the small box from falling through the removal gap 103; when the transparent paper of the small box is defective and needs to be removed, the pack remover body 300 is controlled to make way for the removal gap 103, allowing the small box to fall through the removal gap 103.

[0048] For example, such as Figure 9 As shown, the first controller is a PLC controller. The PLC controller is connected to a control bus and receives the turret's operating data through the control bus. The turret's operating data includes at least encoder signals and splice detection signals.

[0049] In practice, the CAN bus can also be selected as the control bus depending on the actual situation. The splice detection signals specifically include manual splice signals and built-in splice signals. The PLC controller can analyze whether the detector for detecting the transparent paper in the small box is malfunctioning based on these signals and control the machine to stop if the detector fails. Furthermore, the PLC controller controls the rejection electromagnet by issuing rejection commands and uses the first detector to detect the rejection electromagnet's position, obtaining position information. This allows for rejection and shutdown when a failure is detected. During the operation of the turret 100, the encoder monitors the step size (i.e., stride) of the turret 100. The PLC controller can receive encoder signals and determine the timing of the rejection device 300's action based on these signals. If the action of the rejection device 300 does not match the detection of the first detector, it can be inferred that the rejection device is malfunctioning.

[0050] This structural design, based on existing packaging machines, allows for monitoring of the pack rejection device 300 solely through the first detector, preventing delayed or undetected compression of cigarette packs and improving the quality of cigarette packs leaving the factory. The overall structure is relatively simple, easy to install, and highly practical.

[0051] The above provides a detailed description of a translucent paper connector processing device for cigarette packaging boxes provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
