A GDX2000Y packaging machine packaging channel deformation cigarette pack detection device

Abstract

This invention relates to the field of tobacco packaging machinery technology, specifically to a deformed cigarette pack detection device for the packaging channel of a GDX2000Y packaging machine. By fully utilizing and improving the original machine's limiting device in the packaging channel, when deformed cigarette packs pass through the packaging channel during production, the original machine's fixed limiting pressure plate lifts the detection limiting pressure plate upwards, causing the detection baffle to move away from the detector and sending a fault signal to the main machine, thus stopping the machine. This detection device, through a pressure limiting adjustment device, can add deformed cigarette pack detection functionality while fulfilling the original machine's limiting function. Furthermore, the detection sensitivity and accuracy are adjustable, enabling effective and accurate detection of deformed cigarette packs in critical areas, allowing for timely equipment shutdown and minimizing the backward transmission of deformed cigarette packs, thus protecting the equipment from damage.

Description

Technical Field

[0001] This invention relates to the field of tobacco packaging machinery technology, specifically to a device for detecting deformed cigarette packs in the packaging channel of a GDX2000Y packaging machine. Background Technology

[0002] The GDX2000Y packaging machine is a packaging equipment for hard-pack slim cigarettes, with a theoretical design speed of 500 packs / minute. It primarily packages small packs of cigarettes, and its main functional modules include: a molded box conveyor belt, rollers 1 and 2 for inner lining paper packaging, rollers 3 and 4 for cardboard packaging, roller 5 for small box label packaging, and a cigarette pack drying and output device. In actual production, due to equipment limitations, packaging processes, and raw material issues, damaged or deformed cigarette packs often occur sporadically or continuously. The original equipment's deformed cigarette pack detection device for the packaging channel relies on a combination of limit devices and proximity switches. This device suffers from problems such as unreasonable settings, excessive deformation detection margin, poor detection accuracy, and difficulty in triggering. Since the equipment's introduction, cigarette pack deformation alone has caused varying degrees of damage to different functional modules on multiple sets of equipment, severely impacting production efficiency and increasing maintenance frequency.

[0003] In view of the above problems, the inventors of this invention have finally obtained this invention after a long period of research and practice. Summary of the Invention

[0004] To address the aforementioned technical deficiencies, this invention provides a deformed cigarette pack detection device for the packaging channel of a GDX2000Y packaging machine. By improving and utilizing the original machine's limiting device for the packaging channel, a deformed cigarette pack detection device is added while still fulfilling the limiting function. Furthermore, the installation position, sensitivity, and accuracy of the detection device are optimized. This allows for the detection of deformed cigarette packs in critical areas, enabling the equipment to stop promptly and minimizing the backward transmission of deformed cigarette packs, thus protecting the equipment from damage.

[0005] The technical solution adopted in this invention is as follows:

[0006] A device for detecting deformed cigarette packs in the packaging channel of a GDX2000Y packaging machine is provided, comprising a movable limiting pressure plate and a fixed limiting pressure plate disposed in the packaging channel of the packaging machine, wherein the movable limiting pressure plate is located directly above the fixed limiting pressure plate;

[0007] The deformed cigarette pack detection device also includes a detection limiting pressure plate, a detection baffle, and a detector. The detection limiting pressure plate is movably installed at the cigarette pack inlet end of the movable limiting pressure plate. The first end of the detection baffle is connected to the detection limiting pressure plate, and the second end of the detection baffle is located below the detector. The detector is connected to or communicates with the control system of the packaging machine.

[0008] When the detection limit plate is lifted by the deformed cigarette pack, it causes the second end of the detection baffle to tilt downward. The detector detects the movement of the detection baffle and sends a fault signal to the control system of the packaging machine, causing the packaging machine to stop.

[0009] Furthermore, the rear end of the detection limiting pressure plate is hinged to the movable limiting pressure plate via a bracket, and the front end of the detection limiting pressure plate can be flipped upward.

[0010] Furthermore, the first end of the detection baffle is fixed on the bracket, and the vertical position of the detection baffle relative to the bracket is adjustable.

[0011] Furthermore, a pressure regulating device is installed on the detection baffle. The pressure regulating device includes a stud, a spring, and a limit adjusting nut. The detection baffle has a mounting through hole, through which the stud passes. Its bottom is connected to the upper surface of the movable limit pressure plate, and its upper part is threadedly connected to the limit adjusting nut. The spring is fitted on the stud and is located between the detection baffle and the movable limit pressure plate. The limit adjusting nut is located above the detection baffle. By adjusting the position of the limit adjusting nut on the stud, the elastic force of the spring is adjusted, thereby realizing the adjustment of the limiting pressure of the detection limit pressure plate on the cigarette pack, and correspondingly realizing the adjustment of detection sensitivity and accuracy.

[0012] Furthermore, the detector is fixed to the movable limiting pressure plate by a detector bracket, and the front-to-back and height positions of the detector are adjustable.

[0013] Furthermore, the two ends of the bracket are hinged to both sides of the cigarette pack inlet end of the movable limiting pressure plate.

[0014] Furthermore, the bottom surface of the detection limiting pressure plate is parallel to the upper surface of the fixed limiting pressure plate, and can serve as the front extension of the movable limiting pressure plate to limit the cigarette pack.

[0015] Furthermore, it is installed in the packaging channels of the No. 3 and No. 4 wheels of the GDX2000Y packaging machine.

[0016] Furthermore, the detector is a proximity switch.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The GDX2000Y packaging machine cigarette pack deformation detection device of this invention features an adjustable pressure device, thereby improving the trigger sensitivity, accuracy, and timeliness of the detection. By fully utilizing and improving the limiting devices of the No. 3 and No. 4 wheels of the packaging equipment's packaging channel, multiple sets of detection devices can be added, allowing for segmented and modular detection. This ensures detection effectiveness while significantly improving detection accuracy and detection rate, maximizing equipment protection from damage and increasing production efficiency.

[0024] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0025] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] The GDX2000Y packaging machine is equipped with a movable limiting pressure plate 1 and a fixed limiting pressure plate 6 in the packaging channel during the cigarette pack transfer process of the No. 3 and No. 4 wheels. This invention makes full use of and improves the original limiting pressure plate by adding a deformed cigarette pack detection structure to the movable limiting pressure plate 1, which can detect deformed cigarette packs generated during the packaging process in a timely manner and prevent deformed cigarette packs from being transferred backward and causing equipment damage.

[0029] like Figure 1 , Figure 2 As shown, the deformed cigarette pack detection device includes a movable limiting plate 1 and a fixed limiting plate 6 installed in the packaging channel of the packaging machine. It also includes a detection limiting plate 5, a detection baffle 4, and a detector 3. The movable limiting plate 1 is located directly above the fixed limiting plate 6. During the transmission of the cigarette pack in the packaging channel, it passes between the movable limiting plate 1 and the fixed limiting plate 6, which limit the vertical movement of the pack. The detection limiting plate 5 is movably installed at the cigarette pack inlet end of the movable limiting plate 1. The first end of the detection baffle 4 is connected to the detection limiting plate 5, and the second end of the detection baffle 4 is located below the detector 3. The detector 3 is connected to or communicates with the control system of the packaging machine. When the detection limiting plate 5 is lifted by a deformed cigarette pack, it causes the second end of the detection baffle 4 to tilt downwards. The detector 3 detects the movement of the detection baffle 4 and sends a fault signal to the control system of the packaging machine, causing the packaging machine to stop.

[0030] The rear end of the detection limiting pressure plate 5 is hinged to the movable limiting pressure plate 1 via the bracket 7, and the front end of the detection limiting pressure plate 5 can be flipped upward. The first end of the detection baffle 4 is fixed to the bracket 7, and the vertical position of the detection baffle 4 relative to the bracket 7 is adjustable.

[0031] like Figure 3 , Figure 4 As shown, specifically, the two sides 71 of the bracket 7 are hinged to the two sides of the cigarette pack inlet end of the movable limiting pressure plate 1 via hinges 8. The rear end of the detection limiting pressure plate 5 is provided with an elongated hole 51. Bolts pass through the elongated hole to fix the detection limiting pressure plate 5 to the bracket 7. The height of the detection limiting pressure plate 5 can be adjusted by adjusting the position of the bolts in the elongated hole. The bottom surface of the detection limiting pressure plate 5 is parallel to the upper surface of the fixed limiting pressure plate 6, and can serve as an extension of the front end of the movable limiting pressure plate 1 to limit the cigarette pack. Preferably, the bottom surface of the detection limiting pressure plate 5 is slightly lower than the bottom surface of the movable limiting pressure plate 1, that is, the detection limiting pressure plate 5 has the limiting function of the original packaging channel pressure plate. At the same time, when there is a deformed cigarette pack, the detection device will lift the detection limiting pressure plate 5 upward under the action of the original fixed pressure plate 6, and then drive the detection baffle 4 away from the detector 3 through the action of the hinge. At this time, the detector 3 sends a fault signal to the host, causing the host to stop. The bottom of the front end of the detection limiting pressure plate 5 is chamfered to facilitate the entry of the cigarette pack.

[0032] The detection baffle 4 is equipped with a pressure regulating device 9. The detection limit plate 5 can achieve the function of limiting the cigarette pack in the packaging channel and obtain the best detection sensitivity and accuracy through the pressure regulating device 9. The pressure regulating device 9 includes a stud, a spring 91, and a limit adjusting nut 92. The detection baffle 4 has a mounting through hole through which the stud passes. The bottom of the stud is fixed to the upper surface of the movable limit pressure plate 1, and the upper part of the stud is threadedly connected to the limit adjusting nut 92. The spring 91 is fitted on the stud. The spring 91 is located below the detection baffle 4, and the limit adjusting nut 92 is located above the detection baffle 4. By adjusting the position of the limit adjusting nut 92 on the stud, the elastic force of the spring 91 is adjusted, thereby realizing the adjustment of the pressure change of the cigarette pack in the packaging channel by the detection limit pressure plate 5. Correspondingly, the detection sensitivity and accuracy of the detection device can be adjusted. At the same time, under the action of the spring, the detection limit pressure plate 5 can realize the original function of limiting the cigarette pack in the packaging channel. If a deformed cigarette pack is detected, the detection limit pressure plate 5 can be reset under the action of the spring force after the fault is eliminated.

[0033] Preferably, detector 3 is a proximity switch, mounted on movable pressure plate 1 via detector bracket 2. Detector 3 can be adjusted in front-to-back and in height via the bracket. Specifically, detector bracket 2 has a Z-shaped structure with an elongated hole at its lower end. A bolt passes through this elongated hole and connects to movable limiting pressure plate 1. The front-to-back position of detector 3 is adjusted by adjusting the position of the bolt in the elongated hole. Detector 3 is mounted on the upper end of detector bracket 2, which has a mounting hole. Detector 3 is fixed vertically through this mounting hole, and its position within the mounting hole is adjustable in height.

[0034] The above are merely preferred embodiments of the present invention and are illustrative rather than restrictive. The structure and connection methods of the components in the present invention can be varied, and any equivalent transformations and improvements made based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
