Description

Technical Field

[0001] This invention relates to the field of tobacco packaging technology, and in particular to a box-opening and recycling mechanism used after automatic feed of filter rods. Background Technology

[0002] Currently, filter rod feeding is all done manually. The specific process is as follows: Workers take out boxes filled with filter rods 7 (e.g., ...) from the filter rod tray. Figure 1 Manually open the top cover 5 of the filter rod box 6 (hereinafter referred to as the box) and place it on the feeding channel below the unloading machine. After the box passes through the unloading machine, the filter rods are used up. The unloading machine has a discharge channel, and the empty boxes flow out from inside the unloading machine and are arranged vertically on the discharge channel. At the end of the discharge channel, there is a box pushing mechanism, which pushes the empty boxes on the outermost side of the discharge channel (perpendicular to the paper side outward) from left to right, and transfers them to the outside of the unloading machine via the belt conveyor channel. At this time, the empty filter rod boxes (hereinafter referred to as empty boxes) need to be manually removed from the channel and recycled. The current box unpacking and stacking method is roughly as follows. Figure 2 As shown. The disadvantages of the prior art are as follows:

[0003] The manual process of retrieving and recycling boxes from the unloading machine's discharge channel involves a high frequency of work and is quite labor-intensive.

[0004] The boxes are made of a relatively tough material, making them difficult to open manually. Furthermore, the current opening methods depend on the worker's skill level, and high-intensity work can sometimes lead to severe damage to the boxes, hindering recycling.

[0005] Because the empty boxes after disassembly are manually stacked in recycling bins, the actual number is... Figure 2 The situation shown is more chaotic, which will cause inconvenience to the subsequent recycling and packaging work.

[0006] The entire unpacking and recycling process lacks standardized procedures and has a low level of automation, which can easily lead to a messy production environment, is not conducive to establishing a good corporate image, and does not conform to the general trend of modern factory automation and intelligent upgrading. Summary of the Invention

[0007] To automate the unpacking and recycling process, improve production efficiency, replace manual unpacking, and reduce labor intensity, this invention provides an unpacking and recycling mechanism with an optimal unpacking method to increase box reuse rate and a reasonable recycling process for easy production management.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

A suction cup is installed on the movable plate. The left push plate and the right push plate can move horizontally to the left and right relative to the fixed plate, respectively. A pressure plate is installed on the fixed plate and is arranged opposite to the movable plate. The lower push plate can move up and down relative to the fixed plate.

[0011] The flipping mechanism picks up the empty box that is pressed onto the moving plate by the pressure plate and flips the empty box from a vertical state to a horizontal state.

[0012] The recycling mechanism collects the empty boxes stacked horizontally.

[0013] The movable plate is movably connected to a support plate below it, and the support plate is driven to rotate by a cylinder.

[0014] Both sides of the movable plate are provided with stop levers, and the stop levers include a rotary cylinder and a stop block driven by the rotary cylinder.

[0015] The fixed plate, left push plate, right push plate, and lower push plate are all driven by cylinders.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0048] The layout of the unloading machine and the box unpacking and recycling mechanism is as follows: Figure 3 As shown. The upstream end of the conveyor channel 1 is connected to the unloading machine 2, and the downstream end is connected to the box unpacking and recycling mechanism 3. The unloading machine has a discharge channel 201, through which empty boxes flow out and are arranged vertically on the discharge channel. The box pushing mechanism at the end of the discharge channel pushes the empty boxes on the outermost side (perpendicular to the paper side outward) of the discharge channel from left to right, and then transmits them through the middle belt conveyor channel to the box unpacking and recycling mechanism on the right.

[0049] The box unpacking and recycling mechanism consists of an upper box unpacking and flattening mechanism 31, a middle flipping mechanism 32, and a lower recycling mechanism 33, making the entire box unpacking and recycling process have three stations: flattening station A, flipping station B, and recycling station C. The flattening station is at the initial position of the moving plate; the flipping station is at the lowest position where the moving plate is lowered, such as... Figure 3 As shown; the recycling station is on the trolley, and is a material dropping point surrounded by the first guide rod, the second guide rod, and the material dropping plate, as shown. Figure 7 As shown.

[0050] like Figure 4 As shown, the unpacking and flattening mechanism 31 includes a guide rail 3101, a movable plate 3102, a first cylinder 3103, a support plate 3104, first suction cups 3105, and a stop bar 3106. The guide rail 3101 is mounted on a plate connected to the frame, and a slider is installed on the guide rail. The movable plate 3102 is mounted on the slider and is driven up and down by a drive mechanism such as a motor. Four first suction cups 3105 are embedded in the middle of the movable plate 3102. The first cylinder 3103 is fixed to the back of the movable plate 3102, and the piston rod end of the first cylinder is connected to the support plate 3104. The support plate and the lower end of the movable plate are connected by a hinge 3118, allowing the first cylinder to rotate the support plate around the hinge center. The stop bar 3106 consists of a rotary cylinder 3106-1 and a stop block 3106-2, and is fixed to both sides of the guide rail 3101.

[0051] like Figure 5 As shown, the unpacking and flattening mechanism 31 also includes a first fixing plate 3107, a second fixing plate 3108, a third fixing plate 3109, a left push plate 3110, a right push plate 3111, a second cylinder 3112, a third cylinder 3113, a fourth cylinder 3114, a pressure plate 3116, and a lower push plate 3117; the second cylinder 3112 is mounted on a plate connected to the frame. The piston rod of the second cylinder 3112 is connected to the first fixing plate 3107; two second fixing plates 3108 and one third fixing plate 3109 are mounted on the first fixing plate 3107, with the two second fixing plates distributed at the left and right ends of the first fixing plate, and the third fixing plate located at the lower end of the first fixing plate. A third cylinder 3113 is mounted on each of the two second fixed plates 3108. A left push plate 3110 and a right push plate 3111 are respectively mounted on the piston rod ends of the two third cylinders. When the third cylinder 3113 moves, the left and right push plates push out to the left and right, respectively. A pressure plate 3116 is mounted on the second fixed plate 3108. When the second fixed plate 3108 extends forward, the pressure plate 3116 can press down on the empty box in front of the second fixed plate. A fourth cylinder 3114 is mounted on the third fixed plate 3109. A lower push plate 3117 is mounted on the lower end of the piston rod of the fourth cylinder.

[0052] like Figure 6As shown, the flipping mechanism 32 includes a fourth fixed plate 3201, a fifth fixed plate 3202, a first rotating plate 3203, a second rotating plate 3204, a first swing cylinder 3205, a second swing cylinder 3206, and a second suction cup 3207. The fourth fixed plate 3201 is mounted on the conveying channel 1. A bearing is mounted at the lower end of the fourth fixed plate, which rotatably connects to the freely rotating first rotating plate 3203. The fifth fixed plate 3202 is mounted on the first rotating plate 3203. The first swing cylinder 3205 is fixed to the fifth fixed plate 3202, and the piston rod end of the first swing cylinder is fixedly connected to the second rotating plate 3204. Second suction cups 3207 are mounted at both ends of the second rotating plate. To increase the suction force, the second rotating plate is configured in an "I" shape, with second suction cups at each of the four ends. The second swing cylinder is rotatably mounted on the cylinder support 3208. A round bar is installed at the lower end of the piston rod of the second swing cylinder. The two ends of the round bar are respectively connected to the two first rotating plates 3203, so that the first rotating plates and their auxiliary parts can rotate around the rotation center where the bearing is located.

[0053] like Figure 7 As shown, the recycling mechanism 33 includes an electric cylinder 3301, a material discharge plate 3302, a paper pressing frame 3303, a swing pressure plate 3304, a photoelectric sensor 3305, a first guide rod 3306, a second guide rod 3307, and a trolley 3308. A guide rail and a slider are installed on the frame next to the electric cylinder 3301. The electric cylinder drives the slider to move up and down in the guide rail. The electric cylinder is mounted on a plate connected to the frame, and the material discharge plate 3302 is mounted on the slider driven by the electric cylinder. The paper presser 3303 is mounted on the frame and is driven up and down by a drive mechanism (such as a motor). Four swing plates 3304 are mounted on the paper presser, each driven by a cylinder to swing 90° horizontally. This allows the swing plates to switch between two states: retracted to "free end flat against the paper presser" and extended to "free end away from the paper presser." The free end refers to the end not connected to any other object. A photoelectric sensor 3305 is mounted on the left side of the paper presser 3303 to detect whether there are empty boxes on the feed plate. The first guide rod 3306 is fixed to the frame, and the second guide rod 3307 is mounted on the trolley 3308. The trolley's bottom plate has a slot for the feed plate to pass through.

[0054] Empty box flattened state as follows Figure 8As shown. When the photoelectric sensor at the end of the conveyor channel detects an empty box, the first fixing plate extends under the action of the second cylinder, pushing the empty box onto the moving plate that is stationary at the flattening position via the pressure plate. At the same time, the first suction cup holds the empty box, and the first cylinder extends so that the support plate supports the empty box from below. Subsequently, the left and right push plates, under the action of the third cylinder, open the left and right sides of the empty box, and the rotary cylinder drives the stop block to press down on the left and right sides of the empty box; the first cylinder retracts, causing the support plate to open downwards, leaving space for the bottom of the empty box to open. The lower push plate extends under the action of the fourth cylinder, opening the bottom of the empty box, at which point the empty box is completely flattened.

[0055] The movable plate moves downwards, causing the empty box to move downwards to the flipping station. Then, the movable end of the second swing cylinder extends, at which point the flipping mechanism is in the following position: Figure 9 As shown. Then, the first swing cylinder extends, using the second suction cup to pick up the empty box, while the first suction cup is de-aired, completing the transfer of the empty box. Next, the second swing cylinder retracts, moving the empty box out of the flipping station and rotating the fifth fixed plate 90°. At this point, the flipping mechanism is in the following posture: Figure 6 As shown, the empty box is placed horizontally and then moved to... Figure 7 Above the recycling station shown. The first cylinder extends, and the empty box approaches the recycling station.

[0056] At this moment, four swinging pressure plates extend and support the empty box from below, in a posture as follows: Figure 7 The pressure plate at the free end, away from the paper holder, is ready to catch the empty box. The position of the dropping plate is controlled by an electric cylinder, with an initial height slightly lower than the swinging pressure plate, leaving space slightly larger than one empty box. When the second suction cup is de-aired, the empty box will fall onto the extended swinging pressure plate. When the negative pressure of the second suction cup returns to zero, the four swinging pressure plates retract, in the following posture... Figure 7 The pressure plate of the paper presser is shown as being flat against the free end of the paper press. The empty box then falls into the recycling station, and the specific landing point and height are controlled by the first guide rod and the dropping plate.

[0057] When an empty box falls, it sends a signal to the photoelectric sensor on the left, causing the electric cylinder to control the dropping plate to descend a certain height, maintaining sufficient space between the dropping plate and the swing pressure plate. When the photoelectric sensor continuously detects objects, it indicates that the empty boxes have stacked to the designated height, and the trolley needs to be manually replaced.

[0058] Photoelectric sensors can also be installed on the material feeding plate to detect whether there are empty boxes on the material feeding plate. If there are no empty boxes, the material feeding plate will rise directly to the highest point to receive the empty boxes.

[0059] Figure 7 The photoelectric sensor on the left detects the stacking of empty boxes. When the empty boxes are stacked to a certain height, it calls for a manual replacement of the trolley.

[0060] Although the invention has been described herein with reference to illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of this disclosure. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
