Description

Technical Field

[0001] This utility model relates to the field of milk carton packaging technology, and in particular to a milk carton packaging conveying mechanism. Background Technology

[0002] In automated packaging lines for boxed products such as milk cartons, tandem conveyor belts are key equipment for achieving continuous conveying. In actual production, blockages in the conveyor belt channel are one of the main causes of production line interruptions. Specifically, milk cartons, due to their shape (such as slight deformation or bulging) or failure to be accurately positioned in the previous process, may get stuck at specific locations on the conveyor belt, forming an initial blockage point. Once such a blockage occurs, the continuously supplied material will rapidly accumulate behind the blockage point, causing a large area of ​​material stagnation in a very short time. If this blockage is not detected and dealt with immediately, it will directly lead to the shutdown of that section or even the entire production line, severely reducing production efficiency. At the same time, at the blockage point, subsequent material will exert continuous pressure and impact on the stuck material in front, easily causing damage and deformation of the milk carton packaging, resulting in product scrap and economic losses. Utility Model Content

[0003] Therefore, in order to solve the above problems, this utility model proposes a milk carton packaging and conveying mechanism.

[0004] This utility model is achieved through the following technical solution: A milk carton packaging conveying mechanism includes a conveyor belt and a rotating rod mounted above the conveyor belt, and also includes a detection device, which includes a signal generator disposed on one side of the conveyor belt and a signal receiver disposed on the other side of the conveyor belt and corresponding to the signal generator; The rotating rod is provided with a plurality of blocking members, which are evenly arranged along the axial direction of the rotating rod. Each blocking member includes a hinge portion hinged to the rotating rod, a counterweight contact portion disposed on one side of the hinge portion, and a blocking portion disposed on the other side of the hinge portion. The counterweight contact portion has a downward swinging tendency under the action of gravity, and drives the blocking portion to swing upward to a preset position. The preset position is located on the signal path between the signal generator and the signal receiver. When any one of the counterweight contact portions is not lifted, its corresponding blocking portion will block the signal path.

[0005] As a further improvement of this utility model, the signal generator is an infrared probe, and the signal receiver is an infrared sensor.

[0006] As a further improvement of this utility model, a frame rod is also erected above the conveyor belt, and the blocking member is rotatably mounted on the frame rod, so that the counterweight contact part is supported.

[0007] As a further improvement of this utility model, the counterweight contact part is provided with a counterweight block.

[0008] As a further improvement of this utility model, in the conveying direction of the conveyor belt, partition assemblies are respectively provided on the front and rear sides of the detection device. The partition assemblies together divide the conveyor belt into several travel channels for milk cartons to pass through, and the travel channels are correspondingly arranged with the blocking members.

[0009] As a further improvement of this utility model, the partition assembly includes a partition, and uprights are provided on both sides of the conveyor belt. Two crossbeams with a preset spacing are mounted on the uprights, and a mounting seat that can slide along its length direction is provided between the two crossbeams. The partition is mounted on the mounting seat.

[0010] As a further improvement of this utility model, a vertically arranged screw is threaded onto the mounting base, the lower end of the screw passes downward through a preset gap between the crossbeams, a sleeve is sleeved on the screw, the side wall of the sleeve is connected to the partition plate, and the lower end of the screw is provided with a bearing end for supporting the sleeve.

[0011] As a further improvement of this utility model, the length of each of the partitions located at the input end of the conveyor belt decreases sequentially from the middle to both sides.

[0012] As a further improvement of this utility model, a handwheel is provided at the upper end of the screw.

[0013] The beneficial effects of this utility model are as follows: When a blockage occurs on the conveyor belt, and the milk carton cannot reach and push up the corresponding blocking component, the blocking component will immediately block the detection signal, thereby triggering an alarm or shutdown. This allows for timely intervention before large-scale blockages and production line paralysis occur, effectively avoiding the shutdown of the entire line due to blockages and significantly improving production efficiency.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0017] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0018] refer to Figures 1 to 3 The present invention discloses the following embodiments: A milk carton packaging conveying mechanism includes a frame, a conveyor belt 1 mounted on the frame, a rotating rod 2 mounted above the conveyor belt 1, and a detection device. The detection device includes a signal generator 3 mounted on one side of the conveyor belt 1 and a signal receiver 4 mounted on the other side of the conveyor belt 1 and corresponding to the signal generator 3. The rotating rod 2 is provided with a plurality of blocking members 5, each blocking member 5 being evenly arranged along the axial direction of the rotating rod 2. Each blocking member 5 includes a hinge portion 501 hinged to the rotating rod 2, a counterweight contact portion 502 mounted on one side of the hinge portion 501, and a... A blocking part 503 (blocking plate) is located on the other side of the hinge part 501. The counterweight contact part 502 tends to swing downwards under gravity, causing the blocking part 503 to swing upwards to a preset position. This preset position is located on the signal path between the signal generator 3 and the signal receiver 4. When any counterweight contact part 502 is not lifted, its corresponding blocking part 503 will block the signal path. Furthermore, in this embodiment, an alarm device (e.g., a buzzer) and a stop mechanism (an existing mechanism, not present in this embodiment) are also provided on one side of the frame located on the conveyor belt 1. (Improvements will not be described here). During operation, when the milk carton is conveyed forward by the conveyor belt 1 and passes under the blocking member 5, the top of the milk carton will contact the counterweight contact part 502 and lift it up. At this time, the counterweight contact part 502 swings upward, and through the hinge part 501, it drives the blocking part 503 to swing downward, causing it to leave the signal path. At this time, the signal receiver 4 can receive the signal emitted by the signal generator 3, indicating that the milk carton is being conveyed normally at that position. If a certain travel channel 7 of the conveyor belt 1 is blocked, the milk carton cannot reach and lift the corresponding blocking member. When component 5 is in operation, under the influence of gravity, the counterweight contact part 502 swings downward, causing the blocking part 503 to swing upward to the signal path between the signal generator 3 and the signal receiver 4 (i.e., the preset position). At this time, the blocking part 503 blocks the signal path, and the signal receiver 4 cannot receive the signal. After a certain period of time (3-5 seconds), the device alarm or the conveyor belt 1 stop mechanism is triggered, thereby realizing real-time monitoring of the milk carton conveying status and effectively avoiding production line failures caused by milk carton blockage. In addition, the blocking part 5 does not require external power and automatically resets by gravity, which is fast-responding, low-cost, and easy to maintain.

[0019] In addition, this conveying mechanism is equipped with a controller (not shown in the figure). The controller is electrically connected to the detection device to process the signals fed back by the signal receiver 4 and control the alarm device and the shutdown mechanism to start and stop according to the signal status. It is worth noting that during normal interval conveying, when one milk carton leaves and the next milk carton has not yet arrived, the blocking member 5 will also temporarily block the signal due to lack of lifting. In order to accurately distinguish between this normal conveying interval and abnormal blockage fault, the controller of this embodiment has a preset delay judgment program. Only when the signal is continuously blocked for a longer than a preset delay threshold (a certain time as mentioned above, i.e., 3-5 seconds, this threshold is set according to the speed of the conveyor belt 1 and the distance between the milk cartons, usually slightly larger than the normal interval time), will the control system determine that the channel is blocked and immediately trigger the alarm device or the shutdown mechanism. This delay judgment mechanism ensures that the system only responds to continuous and abnormal signal blocking (i.e., blockage) and ignores normal and intermittent signal changes, thereby realizing accurate and reliable detection of blockage faults under interval conveying conditions.

[0020] The signal generator 3 is an infrared probe, and the signal receiver 4 is an infrared sensor. Infrared signals have the characteristics of strong directionality and good anti-interference ability, which can accurately identify whether the blocking part 503 blocks the signal path, reduce false alarms and missed alarms, and enhance system stability and accuracy.

[0021] A support rod 6 is also erected above the conveyor belt 1. The blocking member 5 is rotatably mounted on the support rod 6, and the counterweight contact part 502 is supported. This means that the blocking member 5 in this embodiment has two states - detection state and non-detection / maintenance state. Specifically, in the detection state, the blocking member 5 is rotated to disengage from the support rod 6. At this time, the counterweight contact part 502 naturally swings down under the action of gravity, while the blocking part 503 rises to the signal path area, and the detection function is activated. The milk carton on the conveyor belt 1 can lift the counterweight contact part 502, causing the blocking part 503 to swing to clear the signal path. In the non-detection / maintenance state: when the production line needs to convey other specifications of products that do not require detection, or when cleaning or maintaining the equipment, the operator can simply flip all the blocking parts 5 one by one and set them on the support rod 6. In this state, the counterweight contact parts 502 of all the blocking parts 5 are set on the support rod 6, and the corresponding blocking parts 503 of all the blocking parts 5 are fixed in the flipped position completely away from the signal path. At this time, the signal receiver 4 can always receive the signal emitted by the infrared probe, the detection device switches to the off state, and the conveyor belt 1 can run normally without triggering an alarm or shutdown mechanism, thereby realizing the switching of the detection function and greatly improving the compatibility and ease of operation of the equipment.

[0022] When the counterweight contact part 502 is not heavy enough, it may not be able to swing down reliably under vibration or inertia, causing the blocking part 503 to not swing up sufficiently to the signal path, resulting in missed detection. Based on this, the counterweight contact part 502 is provided with a counterweight block 504 to ensure that the blocking part 503 can reliably rise to the preset position without being lifted, thereby improving the sensitivity and reliability of blockage detection.

[0023] In the conveying direction of the conveyor belt 1, partition 8 assemblies are respectively arranged on the front and rear sides of the detection device. The partition 8 assemblies together divide the conveyor belt 1 into several travel channels 7 for milk cartons to pass through. The travel channels 7 are correspondingly arranged with the blocking members 5. The partition 8 assemblies are arranged on the front and rear sides of the conveying detection device to divide the conveyor belt 1 into several travel channels 7. Each travel channel 7 corresponds to a blocking member 5. The milk cartons are restricted to travel in their respective channels to avoid cross-interference between milk cartons. This ensures that each blocking member 5 only detects a single channel, improves the accuracy and efficiency of blockage detection, and reduces the overall probability of blockage.

[0024] When the partition 8 assembly is fixedly installed, it cannot accommodate milk cartons of different sizes, resulting in the travel channel 7 being too wide or too narrow, causing milk cartons to jam or tip over, requiring frequent replacement of parts, and affecting production efficiency. Based on this, the partition 8 assembly in this embodiment includes a partition 8, and uprights 9 are provided on both sides of the conveyor belt 1. Two crossbeams 10 with a preset spacing are mounted on the uprights 9, and a mounting seat 11 that can slide along its length is provided between the two crossbeams 10. The partition 8 is set on the mounting seat 11. By moving the mounting seat 11, the position of the partition 8 is adjusted to change the width of the travel channel 7, thereby accommodating various milk carton sizes and enhancing the versatility and production efficiency of the conveyor belt 1.

[0025] Correspondingly, when the height of the partition 8 is fixed, it may not be able to effectively guide milk cartons of different heights, causing them to sway, tilt, or get stuck in the travel channel 7, which also increases the risk of blockage. Based on this, a vertically arranged screw 12 is threaded onto the mounting base 11. The lower end of the screw 12 passes downward through a preset gap between the crossbeams 10. A sleeve 13 is fitted onto the screw 12, and the side wall of the sleeve 13 is connected to the partition 8. The lower end of the screw 12 is provided with a bearing end 14 for supporting the sleeve 13. By rotating the screw 12, the bearing end 14 can be moved up and down, thereby pushing the sleeve 13 and the partition 8 connected to it to move up and down vertically, realizing flexible adjustment of the height of the partition 8, thus ensuring that the milk cartons travel stably in the channel and reducing blockage and product damage. The length of each of the partitions 8 located at the input end of the conveyor belt 1 decreases sequentially from the middle to both sides, forming an inlet guide structure similar to an inverted funnel. When the milk carton enters from the input end of the conveyor belt 1, the longer partition 8 in the middle first guides the milk carton in the center, while the shorter partitions 8 on both sides gradually guide the milk cartons on the edges to return to their corresponding travel channels 7. This effectively reduces the accumulation and collision of milk cartons at the entrance, allowing the milk cartons to enter each travel channel 7 more smoothly and orderly, reducing the possibility of initial blockage.

[0026] The upper end of the screw 12 is equipped with a handwheel. Operators can easily drive the screw 12 to rotate by rotating the handwheel without the need for additional tools, thereby adjusting the height of the partition 8. The operation is convenient and labor-saving, and it can quickly complete the parameter adjustment before conveying milk cartons of different specifications, shorten the preparation time for production changeover, and improve production efficiency.

[0027] It is worth mentioning that the specific conveying power structure of the conveyor belt 1 in this embodiment is an existing device, mainly composed of a drive motor, a drive roller, a driven roller and a belt. The drive motor drives the drive roller to rotate, and the conveyor belt 1 circulates under the action of friction to transport milk cartons. This embodiment has not made any improvements to it, and will not be described in detail here.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
