Description

Technical Field

[0001] This invention relates to the field of packaging technology, specifically to a drop-type packaging device for lubricating oil packaging. Background Technology

[0002] Drop-type case packers are a new type of case packing equipment, typically consisting of two layers. The upper layer arranges the raw materials to be packed according to their corresponding packing positions via a separate channel, and then conveys them to a retractable support plate or frame that can drop the materials. The lower layer is the carton conveying channel. When both the carton and the raw materials reach the designated positions, the support plate or frame retracts, and the raw materials fall into the carton under gravity. They are then conveyed to the final stage by the lower layer conveyor to complete the sealing process.

[0003] Generally, the sorting device of a packing machine consists of a reciprocating oscillating mechanism at the front end and several partitions at the rear end forming multiple channels. The sorting mechanism transports materials into these channels to complete the material arrangement. However, when oscillating from one channel to another, the oscillating head needs to be clamped by a clamping mechanism to prevent the material from being discharged from the oscillating mechanism during the transition, thus preventing the material from entering the channel normally and causing jamming. This results in the material conveying process being intermittent, which greatly affects the working efficiency of the packing machine.

[0004] To address the aforementioned issues, a Chinese invention patent with publication number CN114735444A proposes a lane-splitting device for continuous product conveying. By setting a telescopic structure at the front end of the swing guardrail, the guardrail can extend and retract forward simultaneously with lane changing, eliminating the need to clamp and stop the raw materials for normal lane changing and greatly improving efficiency.

[0005] However, with the introduction of the telescopic mechanism, the guardrail needs to extend forward when changing lanes. This requires the telescopic guardrail to be in a retracted state before changing lanes. This means that when retracted, there is a distance between the front guardrail and the rear partition without any guide or partition device to provide effective guidance and protection. In high-speed conveying, on the one hand, raw materials are prone to falling off the conveyor belt, and on the other hand, the lack of effective guidance can also lead to raw materials not entering the subsequent channel normally.

[0006] Specifically applied to the field of lubricant packaging, lubricant bottles are typically irregular cuboids, longer in length and relatively narrower in width. Without effective partitions or guide plates, they can easily skew during conveyor belt transport, preventing them from properly entering the partition channels. Furthermore, due to the longer length and narrower width of the bottles, packaging lines generally require more partitions to create more channels. This necessitates a larger swing angle for the oscillating mechanism, increasing the angle of inclination between the oscillating section and the horizontal conveying section. Simultaneously, an excessively large inclination angle also reduces the width of the oscillating section. And for long, narrow packaging bottles… Material jamming is prone to occur at the connection between the inclined and horizontal sections and within the swing guardrail. To prevent this, the length of the inclined section needs to be increased to reduce the inclination angle, which in turn leads to increased production line length and equipment costs. At the same time, the more raw materials are laid flat in one layer, the larger the length and width of the corresponding carton. When packing, the top cover is in a vertical position. An excessively large cover will increase the relative height between the raw materials and the bottom of the carton when the material falls. On the one hand, the impact force is too great when falling, which can easily cause the carton to break. On the other hand, the bottles are also prone to collision after falling, which can easily cause the bottles to be squeezed and deformed, affecting the appearance. Summary of the Invention

[0007] (I) Technical Solution

[0008] To address the aforementioned technical problems, this invention provides a drop-type box packing device for lubricating oil packaging.

[0009] The specific technical solution is as follows:

[0010] A drop-type box packing device for lubricating oil packaging includes a frame and a conveyor belt. A feeding section, a separating section and a discharging section are respectively provided on the upper part of the conveyor belt along the forward direction of the conveyor belt. A drop device is provided on one side of the discharging section.

[0011] The feeding section includes a set of first guardrails fixed on the frame. There are two first guardrails with a channel in the middle for material to pass through.

[0012] The material distribution section includes swing guardrails, telescopic guardrails, connectors, and a drive mechanism for moving the swing and telescopic guardrails. The drive mechanism includes a first linear slide, a second linear slide, a first linear guide rail, and a second linear guide rail. There are two first linear slides arranged parallel to each other along the width of the conveyor belt. The second linear slide is arranged along the length of the conveyor belt, with both ends fixed to the slides of the two first linear slides. There are two first linear guide rails arranged along the length of the conveyor belt and located on either side of the second linear slide. Both ends of the second linear guide rail are fixed to the slides of the two first linear guide rails. The upper part of the connector is connected to… The slide base of the second linear slide table and the slide base of the second linear guide are both fixedly connected. The lower part of the connector is "door" shaped. The swing guardrail includes multiple horizontally arranged beams located on two vertical planes, forming a channel between the two vertical planes. The beams of the swing guardrail are telescopic structures, and the two ends of the beams are movably connected to the first guardrail and the connector, respectively. The telescopic guardrail also includes multiple horizontally arranged beams located on multiple vertical planes. The beams of the telescopic guardrail are also telescopic structures. The multiple vertical planes are parallel to each other, and a channel is formed between two adjacent vertical planes. One end of the telescopic guardrail corresponding to the beam is fixedly connected to the discharge section, and the other end is fixedly connected to the slide rail of the second linear guide.

[0013] The discharge section includes multiple parallel dividing plates. Two adjacent dividing plates form a channel, and the channels formed by the dividing plates correspond one-to-one with the channels formed by the telescopic guardrail. The crossbeams in the telescopic guardrail are fixedly connected to one end of the dividing plate. A pressing cylinder and a pressing block are provided at the end of the dividing plate away from the material distribution section. A pressing cylinder and a pressing block are provided in the middle of two adjacent dividing plates.

[0014] Furthermore, a counting sensor is fixed on the connector head, and when the sliding direction of the second linear slide is the same as the forward direction of the conveyor belt, the sliding speed of the second linear slide is equal to the forward speed of the conveyor belt.

[0015] Furthermore, the channels formed by the connectors and the telescopic guardrails are equipped with corresponding alignment sensors.

[0016] Furthermore, the connector specifically includes a fixed plate, a movable plate, and a horizontal plate. The horizontal plate is fixedly connected to the slide base of the second linear slide table and the slide base of the second linear guide rail. The lower part of the horizontal plate is provided with parallel guide posts and screws. One end of the screw is provided with a handwheel. By rotating the handwheel, the movable plate can be driven to slide on the guide post, and the alignment sensor can also slide on the guide post.

[0017] Furthermore, the swing guardrail specifically includes a swing section and a guide section. Both the swing section and the guide section include two sets of horizontally arranged crossbeams, which are distributed in parallel to form a channel. The crossbeams of the guide section are telescopic structures. The crossbeams of the swing section and the crossbeams of the guide section are connected by a connecting mechanism. The crossbeams of the swing section are connected to the first guardrail by the connecting mechanism. The connecting mechanism can form an arc-shaped channel. A gantry with an opening facing downwards is fixed on the second linear slide. One end of the crossbeam of the guide section is fixed to the gantry, and the channel formed by the guide section is parallel to the channel formed by the dividing plate. Driven by the two first linear slides, the channel formed by the guide section corresponds one-to-one with the channel formed by the telescopic guardrail. An adjustment frame is provided on the upper part of the swing section to adjust the width of the channel formed between the crossbeams of the swing section.

[0018] Furthermore, the connecting mechanism includes an elastic plate, a sliding groove, and a chain formed by multiple chain links connected end to end by pins. The elastic plate is curved and serpentine, and has a ball groove and balls on one side. The elastic plate can stretch or rebound within the sliding groove using its own elasticity. The chain links specifically include an upper plate, a lower plate, a front plate, and a back plate. The width of the middle part of the upper plate and the lower plate is greater than the width at both ends, forming a bevel. The middle parts of two adjacent chain links are hinged by pins. A ball is provided on one side of the front plate. Circular limit blocks are provided at both ends of the pins. Corresponding limit grooves are provided in the sliding groove. One end of the chain is connected to the elastic plate, and the other end of the elastic plate and the other end of the chain are connected to the corresponding crossbeam.

[0019] Furthermore, the drop device includes partitions, a drop frame, a bottle-blocking mechanism, and a sliding mechanism corresponding to the drive partitions and the drop frame. There are multiple partitions, the same number as the guide plates, and the partitions and guide plates are coplanar and correspond to each other. The drop frame includes a vertically arranged first rib, a second rib arranged along the width of the conveyor belt, and a support rib arranged along the forward direction of the conveyor belt. The number of first ribs is one less than the number of partitions, and the distance between two adjacent first ribs is the same as the distance between two adjacent partitions. The support ribs are in two layers, with the number of upper support ribs corresponding to the number and position of the channels formed by the partitions, and the upper support ribs and lower support ribs are staggered. When the upper support ribs are close to the side of the partitions, the lower support ribs are located in the middle of the channels formed by two adjacent partitions. The sliding mechanism includes a frame, a slide bar, a slider, and a sliding cylinder. The upper part of the first ribs is fixed to the frame, and the frame is fixed to the slider. Under the action of the sliding cylinder, the drop frame reciprocates in the horizontal direction.

[0020] Furthermore, the bottle-blocking mechanism includes a rotating shaft and a limiting member. The limiting member is connected to the rotating shaft in the middle, and there are multiple limiting members located in the middle of multiple partitions. One end of the limiting member is a baffle, specifically including a horizontal baffle and a connecting strip. The horizontal baffle is located at the end of the connecting strip away from the rotating shaft. The other end of the limiting member is provided with a baffle plate. The upper part of the frame is provided with a signal transmitter and a receiver, and their positions correspond to the baffle plate.

[0021] Furthermore, the limiting component has an arc-shaped groove on the side near the baffle, the baffle is located in the arc-shaped groove and can slide and be fixed in the arc-shaped groove, the frame is provided with a limiting plate to control the limit stroke of the limiting component's rotation, and the slider is provided with a photoelectric sensor for alignment.

[0022] (ii) Beneficial effects

[0023] (1) By setting telescopic guardrails and swing guardrails, when the swing guardrail retracts, the telescopic guardrail extends, and when the swing guardrail extends, the telescopic guardrail retracts. On the one hand, this ensures uninterrupted feeding, and on the other hand, there are corresponding guardrails to guide and protect the material throughout the feeding process, preventing jamming and preventing the packaging bottles from falling off the conveyor belt.

[0024] (2) By setting a connecting mechanism at both ends of the swing guardrail, an arc-shaped channel can be formed instead of an inclined channel. This can effectively ensure that the packaging bottle passes through the arc-shaped channel normally, and at the same time, the tilt angle will not change the size of the spacing inside the swing guardrail, thus preventing the bottle from getting stuck.

[0025] (3) The double-layer staggered drop position can effectively reduce the height difference between the packaging bottle and the carton, and prevent the carton and packaging bottle from being damaged due to collision during the drop.

[0026] (4) The arc-shaped strip adjusts the sensing position, making it more suitable for sensing the position of irregularly shaped packaging bottles. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the invention, not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0051] In the relevant existing technologies, the telescopic guardrail is in a retracted state before lane change. There is a distance between the front guardrail and the rear partition without any guide or partition device to effectively guide and protect it. This makes it easy for raw materials to fall off the conveyor belt. At the same time, the swing mechanism needs to swing at a larger angle, that is, the tilt angle between the swing section and the horizontal conveying section is increased. The excessive tilt angle also makes the width of the swing section smaller, which is easy to cause material jamming. In addition, the drop height is large, which can easily cause the packaging bottles to collide and deform after falling.

[0052] Example 1

[0053] To address the problems existing in the relevant prior art, this invention proposes a drop-type box packing device for lubricating oil packaging. Please refer to the following for details. Figures 1 to 3 Specifically, it includes a frame 1 and a conveyor belt 2. The conveyor belt 2 is fixed on the frame 1. The conveyor belt 2 is a conventional chain plate conveyor belt. Along the forward direction of the conveyor belt 2, there are feeding section 3, sorting section 4 and discharge section 5 on the upper part of the conveyor belt 2. A drop device 6 is provided on one side of the discharge section 5. The feeding section 3 is connected to the front-end bottling machine and is used to transport bottled lubricating oil to the rear end for drop boxing. The sorting section 4 is a reciprocating swing structure that divides the single-row conveyed packaging bottles into multiple rows of conveyors, which enter the discharge section 5. The packaging bottles that enter the discharge section 5 are conveyed by the conveyor belt 2 and then drop boxed after being transported by the final drop device 6.

[0054] Specifically, the feeding section 3 includes a set of first guardrails 3a fixed on the frame 1. The first guardrails 3a are plate-shaped or have a structure including crossbeams and columns. There are two first guardrails 3a, and a channel for material to pass through is formed in the middle. Normally, the width of the channel is slightly larger than the width of the packaging bottle.

[0055] Please continue reading 1 and... Figure 2The material distribution section 4 is fixed on the frame 1, specifically including a swing guardrail 4a, a telescopic guardrail 4b, a connector 4c, and a drive mechanism 4d for driving the swing guardrail 4a and the telescopic guardrail 4b. The drive mechanism 4d includes a first linear slide 4da, a second linear slide 4db, a first linear guide rail 4dc, and a second linear guide rail 4dd. There are two first linear slides 4da, arranged parallel to each other along the width of the conveyor belt 2, both facing downwards. The second linear slide 4db is arranged along the length of the conveyor belt 2, also facing downwards. The two ends of the second linear slide 4db are respectively fixed on the slide seats of the two first linear slides 4da, meaning that the second linear slide 4db can slide back and forth along the width direction of the conveyor belt 2 under the drive of the two slide seats of the two first linear slides 4da. There are two first linear guides 4dc, which are set along the length direction of the conveyor belt 2 and are located on both sides of the second linear slide 4db. The two ends of the guide rail of the second linear guide 4dd are respectively fixed on the slide seats of the two first linear guides 4dc. The upper part of the connector 4c is connected to the slide seats of the second linear slide 4db and the second linear guide 4dd. All slides are fixedly connected, meaning that under the drive of the slide of the second linear slide table 4db, the second linear guide rail 4dd can reciprocate along the length of the conveyor belt 2. Specifically, the lower part of the connector 4c is "gate" shaped. The swing guardrail 4a includes multiple horizontally arranged crossbeams 7 located on two vertical planes, forming a channel between the two vertical planes. This channel is interconnected with the channel formed by the first guardrail 3a. The crossbeams 7 of the swing guardrail 4a are telescopic structures, with both ends of the crossbeams 7 movably connected to the first guardrail 3a and the connector 4c, respectively. The telescopic guardrail 4b also includes... Multiple horizontal beams 7 are located on multiple vertical planes, forming multiple channels. The beams 7 of the telescopic guardrail 4b are also telescopic structures. Multiple vertical planes are parallel to each other, and a channel is formed between two adjacent vertical planes. One end of the telescopic guardrail 4b corresponding to the beam 7 is fixedly connected to the discharge section 5, and the other end is fixedly connected to the slide rail of the second linear guide rail 4dd. The telescopic structure of the beams 7 of the swing guardrail 4a and the telescopic guardrail beam 7 is a conventional technology. Specifically, a telescopic structure with telescopic rods and sliding grooves or other alternative structures can be used, which are not specifically limited here.

[0056] Please continue reading. Figure 1 and Figure 2 The discharge section 5 includes multiple parallel dividing plates 5a. Two adjacent dividing plates 5a form a channel. The channels formed by the dividing plates 5a correspond one-to-one with the channels formed by the telescopic guardrail 4b and are interconnected. The crossbeam 7 in the telescopic guardrail 4b is fixedly connected to one end of the dividing plate 5a. A pressing cylinder 5b and a pressing block 5c are provided at the end of the dividing plate 5a away from the material distribution section 5. A pressing cylinder 5b and a pressing block 5c are provided in the middle of two adjacent dividing plates 5a.

[0057] Please see Figure 3A counting sensor 8 is fixed on the connector 4c to count the number of packaging bottles passing through the connector 4c. When the sliding direction of the second linear slide 4db is the same as the forward direction of the conveyor belt 2, the sliding speed of the second linear slide 4db is equal to the forward speed of the conveyor belt 2. Furthermore, the channels formed by the connector 4c and the telescopic guardrail 4b are equipped with corresponding alignment sensors 9. That is, when the connector 4c moves along the width direction of the conveyor belt 2 under the drive of the first linear slide 4da, the alignment sensors 9 ensure that the channel formed at the bottom of the connector and the channel formed by the telescopic guardrail 4b can be accurately aligned to prevent misalignment from causing abnormal conveying.

[0058] The specific working principle is as follows: Figure 2 For example, at this time, the lane divider 5a and the retractable guardrail 4b form 5 channels, according to... Figure 2The channels, numbered from top to bottom as Channel 1, Channel 2, Channel 3... Channel 5, are designed to work from the start. When starting, the swing guardrail 4a extends to its maximum position, the telescopic guardrail 4b retracts, and the channel of the swing guardrail 4a aligns with Channel 1. At this point, the bottles, after being filled in the previous bottling process, enter the middle channel of the first guardrail 3a and move forward under the conveyor belt 2, passing through the channel of the swing guardrail 4a into Channel 1. When the foremost bottle begins to pass the connector 4c, a counting sensor begins counting. Simultaneously, under the action of the second linear slide 4db, the connector 4c moves in the opposite direction to the forward direction of the conveyor belt 2 along its length. This causes the swing guardrail 4a to retract and the telescopic guardrail 4b to extend. After completing the specified count, the connector 4c is controlled to move synchronously with the conveyor belt along its length, with the speed of the connector 4c matching the forward speed of the conveyor belt 2. Simultaneously, under the action of the first linear slide 4da, the connector 4c also moves along the width of the conveyor belt 2. The movement ensures that the connector 4c transitions from alignment with channel one to alignment with channel two. Driven and limited by the second linear slide 4db, the first linear guide 4dc, and the second linear guide 4dd, the telescopic guardrail 4b retracts accordingly. By adjusting the movement speed of the conveyor belt 2 and the first and second linear slides 4da and 4db, the optimal state is that when the first bottle passes through the connector 4c, counting begins, and simultaneously the second linear slide 4db drives the swing guardrail 4a to retract, synchronously extending the telescopic guardrail 4b. When the count is reached, the swing guardrail 4a retracts to its minimum, and the telescopic guardrail extends to its maximum. At this point, the second linear slide 4db drives the connector 4c and the conveyor belt to move in the same direction at the same speed, causing the swing guardrail 4a to extend while the telescopic guardrail 4b retracts. Simultaneously, the two first linear slides 4d work together to switch the connector from channel one to channel two. Because the connector 4c is relatively stationary with the conveyor belt 2 along its length, no bottles will pass through the connector 4c. That is, the time required for the swing guardrail to extend from the retracted state to its maximum travel is the same as the time required for the connector 4c to switch from one channel to two channels. At the same time, the time required for the counting sensor 8 to count to a specified number is the same as the time required for the swing guardrail to retract to its minimum size.

[0059] With the above scheme, when the swing guardrail 4a retracts, the telescopic guardrail 4b extends, and when the swing guardrail 4a extends, the telescopic guardrail 4b retracts. This ensures uninterrupted feeding on the one hand, and on the other hand, there are corresponding guardrails to guide and protect the material throughout the feeding process, preventing jamming and preventing the packaging bottles from falling off the conveyor belt.

[0060] Please see Figure 3The connector 4c specifically includes a fixed plate 4ca, a movable plate 4cb, and a horizontal plate 4cc. The horizontal plate 4cc is fixedly connected to the slide of the second linear slide table 4db and the slide of the second linear guide rail 4dd. The lower part of the horizontal plate 4cc is provided with parallel guide posts 4cd and screws 4ce. One end of the screw 4ce is provided with a handwheel 4cf. By rotating the handwheel 4cf, the movable plate 4cb can be driven to slide on the guide post 4cd. This allows for adjustment of the spacing of the lower channel opening, ensuring that the packaging bottle passes through normally. The alignment sensor 9 can also slide on the guide post 4cd. Adjusting the position of the alignment sensor 9 ensures that it is always in the middle of the channel, guaranteeing accurate alignment.

[0061] Example 2

[0062] Please see Figure 4 Based on Embodiment 1, the swing guardrail 4a specifically includes a swing section 4aa and a guide section 4ab. Both the swing section 4aa and the guide section 4ab include two sets of horizontally arranged crossbeams 7, which are distributed in parallel to form a channel. The crossbeams 7 of the guide section 4ab are telescopic structures. The crossbeams 7 of the swing section 4aa and the crossbeams 7 of the guide section 4ab are connected by a connecting mechanism 10. The crossbeams 7 of the swing section 4aa are connected to the first guardrail 3a by the connecting mechanism 10. The connecting mechanism 10 can form an arc-shaped channel. A gantry 4ac with an opening facing downward is fixed on the second linear slide 4db. One end of the crossbeam 7 of the guide section 4ab is fixed on the gantry 4ac. The channel formed by the guide section 4ab is parallel to the channel formed by the dividing plate 5a. Under the drive of the two first linear slides 4da, the channel formed by the guide section 4ab corresponds one-to-one with the channel formed by the telescopic guardrail 4b. An adjustment frame 4ad is provided on the upper part of the swing section 4aa to adjust the width of the channel formed between the crossbeams of the swing section 4aa.

[0063] Compared to Embodiment 1, in Embodiment 2, the guide section 4ab and the telescopic guardrail 4b move synchronously and correspondingly. Furthermore, the guide section 4ab can move along the width of the conveyor belt 2 to complete the transition between channels. This ensures that the packaging bottles conveyed from the connector are pre-adjusted by the guide section 4ab, preventing tilting and resulting in a smoother entry into the subsequent telescopic guardrail 4b. In contrast, with conventional swing guardrail 4a, as the swing angle increases, the spacing between the channels in the middle of the swing guardrail 4a gradually decreases. This leads to material jamming when the swing guardrail 4a tilts to a certain angle. To reduce the tilt angle, the length of the swing guardrail needs to be increased, leading to increased conveyor line length and cost. In this embodiment, the swing guardrail 4a is divided into swing section 4aa and guide section 4ab, and a connecting mechanism 10 is provided to form an arc-shaped channel. This ensures effective arc-shaped guidance during swinging without changing the distance between the swing sections 4aa, preventing material jamming.

[0064] Please see Figure 5 and Figure 6 The connecting mechanism 10 specifically includes an elastic plate 10a, a groove 10b, and a chain 10e formed by multiple chain links 10d connected end-to-end by pins 10c. The elastic plate 10a is curved and serpentine, and has a ball groove and balls 10f on one side. The elastic plate 10a can stretch or rebound within the groove 10b using its own elasticity. When the elastic plate 10a is stretched, the chain 10e extends further out of the groove 10b, and when the elastic plate 10a contracts, it drives the chain 10e back into the groove 10b. The chain link 10d specifically includes an upper plate 10da, a lower plate 10db, a front plate 10dc, and a back plate 10dd. The upper plate 10da and the lower plate 10db have a width in the middle that is greater than the width at both ends, forming a bevel. Thus, when the chain 10e bends, it will form an arc due to the shape of the chain link 10d. The chain has a shape, and two adjacent chain links 10d are hinged at the middle by a pin 10c. A ball bearing 10f is provided on one side of the main plate, and circular limiting blocks 10g are provided at both ends of the pin 10c. A corresponding limiting groove is provided in the slide groove 10b. One end of the chain 10e is connected to the elastic plate 10a, and the other end of the elastic plate 10a and the other end of the chain 10e are connected to the corresponding crossbeam 7. The above-mentioned connecting mechanism 10 is installed between the swing section 4aa and the guide section 4ab. When the swing section 4aa and the guide section 4ab are aligned, the channel is straight. When the guide section 4ab and the swing section 4aa form an angle, the connection will pull the chain 10e out of the slide groove 10b to form an arc shape. This can effectively avoid the angle forming and the packaging bottle getting stuck at the connection between the swing section 4aa and the guide section 4ab.

[0065] Please see Figures 7 to 9The drop device 6 includes a partition 6a, a drop frame 6b, a bottle-blocking mechanism 6c, and a sliding mechanism 6d that drives the partition 6a and the drop frame 6b to correspond to each other. There are multiple partitions 6a, the same number as the guide plates 5a, and the partitions 6a and guide plates 5a are coplanar and correspond one-to-one. The drop frame 6b includes a vertically arranged first rib 6ba, a second rib 6bb arranged along the width direction of the conveyor belt, and a support rib 6bc arranged along the forward direction of the conveyor belt 2. The number of first ribs 6ba is one less than the number of partitions 6a, and adjacent first ribs 6ba are arranged in a specific manner. The distance between the 6ba supports is the same as the distance between two adjacent partitions 6a. The support ribs 6bc are in two layers, upper and lower. The number of upper support ribs 6bc corresponds to the number and position of the channels formed by the partitions 6a, and the upper support ribs 6bc are staggered with the lower support ribs 6bc. When the upper support ribs 6bc are close to the side of the partition, the lower support ribs 6bc are located in the middle of the channels formed by the two adjacent partitions 6a. The sliding mechanism 6d includes a frame 6da, a slide rod 6db, a slider 6dc, and a sliding cylinder. 6dd, the upper part of the first rib 6ba is fixed to the frame 6da, and the frame 6da is fixed to the slider 6dc. Under the action of the sliding cylinder 6dd, the drop frame 6b reciprocates in the horizontal direction. When the packaged bottle in the divider plate 5a enters the partition plate 6a under the action of the conveyor belt, the upper support rib 6bc supports the packaged bottle. When the packaged bottle reaches the designated position of the bottle blocking mechanism 6c, the sliding cylinder 6dd drives the drop frame 6b to move horizontally, so that the upper support rib 6bc will move. When the bottle is placed against the partition 6a, it will fall. As the drop frame 6b moves, the lower support rib 6bc will be positioned between the two adjacent partitions 6a. That is, the bottle will fall from the upper support rib 6bc to the lower support rib 6bc. Then, the sliding cylinder 6dd will drive the drop frame 6b back to its initial position, and the bottle on the lower support rib 6bc will fall from the bottom to be packed. This secondary drop can effectively reduce the impact of the first drop and prevent the bottle from deforming due to excessive impact.

[0066] Please continue reading. Figures 7 to 9The bottle-blocking mechanism 6c includes a rotating shaft 6ca and limiting members 6cb. The middle of the limiting members 6cb is connected to the rotating shaft 6ca, and there are multiple limiting members 6cb located in the middle of multiple partitions 6a. One end of the limiting member 6cb is a baffle 6cc, specifically including a horizontal baffle 6cd and a connecting strip 6ce. The horizontal baffle 6cd is located at the end of the connecting strip 6ce away from the rotating shaft 6ca. The other end of the limiting member 6cb is provided with a baffle 6cf. The upper part of the frame 1 is provided with a signal transmitter 11 and a receiver 12, and their positions correspond to the baffle 6cf. When the packaging bottle has not entered the middle of the partition, the limiting member is in a vertical state by its own weight. As the packaged product enters the middle of the partition 6a, the packaging bottle pushes up the horizontal bar 6cd, and the limiting member 6cb rotates around the rotating shaft 6ca. When it reaches the predetermined position, it drives the baffle 6cf to be located between the signal transmitter 11 and the receiver 12, blocking normal signal communication, indicating that the position has been reached. It then cooperates with the sliding cylinder 6dd to slide and complete the material dropping. After the material is dropped, the limiting member 6cb returns to the initial position, and the sliding cylinder 6dd also returns to the initial position.

[0067] For easier adjustment of a specified position, please refer to [link / reference]. Figure 9 An arc-shaped groove is provided on the side of the limiting member 6cb near the baffle 6cf. The baffle 6cf is located in the arc-shaped groove and can slide and be fixed in the arc-shaped groove. A limiting piece 13 is provided on the frame 1 to control the limit stroke of the rotation of the limiting member 6cb. A photoelectric sensor 14 for alignment is provided on the slider 6dc. By adjusting the position of the baffle 6cf in the arc-shaped groove, it can be well adapted to bottles of different shapes.

[0068] Please see Figure 10 The specific drop device also needs to be used in conjunction with the bottom carton conveyor line, including roller conveyor 15, carton clamping device 16, lifting platform 17 and lifting motor 18. The carton passes through roller conveyor 15 and arrives at lifting platform 17. The lifting motor drives the carton to rise, and the packaging bottle falling from the upper drop device 6 falls into the carton on lifting platform 17, and then falls back to roller conveyor 15 to complete the receiving. During the receiving process, carton clamping device 16 clamps the subsequent carton. After the receiving is completed, carton clamping device 16 is released, and the next carton enters the lifting platform to complete the same receiving work. This part is an application of existing technology and is not limited to specific applications. The complete and specific workflow will be described below.

[0069] Please see Figure 10The drop-packing equipment includes a two-layer conveyor structure: the upper layer conveys packaging bottles, and the lower layer conveys cartons. Specifically, the upper-layer packaging bottles originate from the previous bottling and capping machines. They are then conveyed in a single channel to the first guardrail 3a at the very front. Multiple packaging bottles pass sequentially through the first guardrail 3a, and then the separating section 4 conveys them to the channels formed by the dividing plates 5a, converting the single-channel to multi-channel simultaneous conveying. As the multiple packaging bottles move forward in their respective channels, the front-end packaging bottle is pushed into the middle of the partition 6a of the drop device. The upper support ribs 6bc, located between two adjacent partitions 6a, support the packaging bottles. The packaging bottles slide between the partitions 6a and simultaneously contact the crossbar 6cd, causing the limiting member 6cb to rotate around the rotating shaft 6ca. When the limiting member 6cb rotates to the designated position, the baffle 6cf releases the signal. The signal from transmitter 11 is blocked, preventing the signal from reaching receiver 12. At this time, the control system controls the pressing cylinder 5b to move downwards, driving the pressing block to press the packaging bottle passing below, preventing the packaging bottle from continuing to be sent into the middle of the partition 6a. Then, the sliding cylinder 6dd drives the drop frame 6b to slide relative to the partition 6a, causing the upper support rib 6bc to move towards the partition. At the same time, the lower support rib 6bc will be in the middle of the channel formed by the two adjacent partitions 6a, and the packaging bottle will fall from the position of the upper support rib to the position of the lower support rib. After the packaging bottle falls, the limiting member 6cb rotates and resets using its own weight, and the signal transmitter and receiver can pass normally. The pressing cylinder 5b lifts up, and the sliding cylinder 6dd also resets, driving the lower support rib 6bc back to its original position. The packaging bottle on the lower support rib falls from the middle of the partition 6a, and then the above steps are repeated.

[0070] During the movement of the packaging bottle, the carton is conveyed on the roller conveyor 15 to the lifting platform 17. The lifting platform 17 drives the carton to rise, so that the height of the top of the carton is level with the height of the upper support rib 6bc. In this way, the lower support rib 6bc is located inside the carton, and the drop height difference of the packaging bottle from the lower support rib 6bc into the carton is smaller, and the impact force is also smaller. This effectively prevents the packaging bottle from being deformed due to excessive impact force. In the traditional structure, the drop frame cannot extend into the carton, resulting in a large height difference, which easily leads to the phenomenon of packaging bottle deformation upon drop.

[0071] After the carton is received, the lifting platform 17 drops, causing the carton to return to the roller conveyor 15. The roller conveyor 15 then transports the carton to the rear end for sealing. At the same time, the receiving process is repeated for the next carton.

[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
