Description

Technical Field

[0001] This utility model relates to the field of PET bottle production technology, specifically to a flexible channeling device for an automatic PET bottle packing machine. Background Technology

[0002] On automated PET bottle packing production lines, traditional sorting devices typically use fixed-spaced sorting baffles or manually adjustable sorting structures, which have the following problems:

[0003] Poor adaptability: It cannot quickly adapt to the switching requirements of different bottle types (such as round bottles, square bottles, irregularly shaped bottles) and packing specifications (such as 6 bottles / box, 12 bottles / box), and the changeover adjustment time is long (about 30 minutes or more), which affects production efficiency.

[0004] Vulnerable bottle body: When the rigid divider comes into contact with PET bottles, it is easy to cause problems such as scratches on the bottle body and loosening of the bottle cap due to collision, especially for thin-walled bottles (approximately 1% to 3%).

[0005] Low lane separation accuracy: Traditional mechanical structures have difficulty dynamically compensating for fluctuations in conveyor belt speed or deviations in bottle arrangement, resulting in uneven lane separation and affecting the accuracy of subsequent packing processes.

[0006] High maintenance costs: The lane divider baffles need to be replaced as a whole after long-term wear and tear, and manual adjustment is difficult, which increases equipment maintenance costs and downtime.

[0007] Therefore, there is an urgent need for a flexible sorting device that can quickly adapt to various bottle types, reduce bottle damage, improve sorting accuracy, and is easy to maintain. Utility Model Content

[0008] The purpose of this invention is to provide a flexible lane separating device for an automatic PET bottle packing machine to solve the problems mentioned in the background art.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0010] A flexible lane-separating device for an automatic PET bottle packing machine includes a conveyor belt, a controller, and a mounting frame. The mounting frame has a lane-separating assembly inside, which is located above the conveyor belt.

[0011] Photoelectric sensor one and photoelectric sensor two are staggered on both sides of the conveyor belt, and an industrial camera is fixedly connected to the top of the mounting frame by a support frame rod.

[0012] The lane separation assembly includes a lane separation baffle one and a lane separation baffle two. A lane separation drive assembly is provided on the side of the lane separation baffle one and the lane separation baffle two that are close to each other. The lane separation drive assembly is used to drive the lane separation baffle one and the lane separation baffle two to change their relative distance.

[0013] A further improvement of the present invention is that: a magnetic suction slot is provided on one side of the second channel baffle, a magnetic suction protrusion is movably engaged on the inner wall of the magnetic suction slot, and a thickened baffle is fixedly connected to the side of the magnetic suction protrusion away from the magnetic suction slot.

[0014] A further improvement of the present invention is that the lane-splitting drive assembly includes a hydraulic rod, and a slider is fixedly connected to the telescopic end of the hydraulic rod. The two sides of the slider are rotatably connected to lane-splitting baffle one and lane-splitting baffle two respectively through two sets of support rods. The telescopic movement of the hydraulic rod is converted into the opposite or opposite movement of lane-splitting baffle one and lane-splitting baffle two through the slider and support rods.

[0015] A further improvement of this utility model is that: a positioning slide is slidably connected to the upper surface of the slider, the bottom surface of the positioning slide near one end is fixedly connected to the upper surface of the fixed end of the hydraulic rod, and the positioning slide is fixed to the top of the inner wall of the mounting frame to limit the movement trajectory of the slider.

[0016] A further improvement of this utility model is that: the upper surfaces of both the first and second lane divider baffles are fixedly connected with guide vertical rods, and the top of the guide vertical rods is slidably connected with a transverse guide rail. The transverse guide rail is fixedly connected to the top of the inner wall of the mounting frame, and is used to guide the first and second lane divider baffles to move smoothly along a straight line.

[0017] A further improvement of this utility model is that: one end of both the first and second channel baffles is fixedly connected with a separation cone, which has a streamlined structure and is used to guide PET bottles into the channel area.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. This utility model provides a flexible lane-separating device for an automatic PET bottle packing machine, with high flexibility and adaptability: it can complete the switching of different bottle types (diameter range 50-120mm) and packing specifications within 5 minutes, significantly shortening the changeover time (80% faster than traditional equipment). Through the modular replacement of the thickened baffle 13, it is compatible with various irregular bottle shapes such as round, square, and oval, and has strong versatility.

[0020] 2. This utility model provides a flexible sorting device for an automatic PET bottle packing machine, featuring low-damage sorting technology: the curved design of the magnetically thickened baffle 13 and the use of elastic materials (such as silicone) reduce the bottle damage rate to below 0.1%, improving product appearance quality. The streamlined structure of the separating cone 11 guides the PET bottles smoothly into separate channels, avoiding bottle deformation or cap loosening due to collisions.

[0021] 3.

A dynamic speed compensation algorithm for high-speed scenarios maintains a lane-separating success rate of over 99.8%.

[0022] 4. This utility model provides a flexible lane-separating device for an automatic PET bottle packing machine, with an easy-to-maintain structural design: the magnetic connection of the thickened baffle 13 facilitates quick replacement of worn parts, reducing maintenance time by 70%. The modular lane-separating assembly 6 can be completely disassembled, facilitating equipment upgrades or troubleshooting.

[0023] 5. This utility model provides a flexible lane-separating device for an automatic PET bottle packing machine, enabling intelligent production collaboration: the controller 4 can communicate with the host computer system, receive production plan instructions, and automatically call preset lane-separating parameters to achieve unmanned changeover.

[0031] The present invention will be further described in detail below with reference to embodiments:

[0032] Example 1

[0033] like Figure 1-5 As shown, this utility model provides a flexible lane separating device for an automatic PET bottle packing machine, including a conveyor belt 1, a controller 4 and a mounting frame 7. The mounting frame 7 is provided with a lane separating component 6, which is located above the conveyor belt 1.

[0034] Photoelectric sensor 1 2 and photoelectric sensor 2 3 are staggered on both sides of the conveyor belt 1, and an industrial camera 5 is fixedly connected to the top of the mounting frame 7 through a support frame rod.

[0035] The lane separation assembly 6 includes a lane separation baffle 1 9 and a lane separation baffle 2 10. A lane separation drive assembly is provided on the side of the lane separation baffle 1 9 and the lane separation baffle 2 10 that are close to each other. The lane separation drive assembly is used to drive the lane separation baffle 1 9 and the lane separation baffle 2 10 to change the relative distance between them.

[0036] A magnetic slot 12 is provided on one side of the lane divider 10. A magnetic protrusion 14 is movably engaged with the inner wall of the magnetic slot 12. A thickened baffle 13 is fixedly connected to the side of the magnetic protrusion 14 away from the magnetic slot 12.

[0037] Example 2

[0038] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the lane-splitting drive assembly includes a hydraulic rod 15, and a slider 16 is fixedly connected to the telescopic end of the hydraulic rod 15. The two sides of the slider 16 are rotatably connected to the lane-splitting baffle 9 and the lane-splitting baffle 10 respectively through two sets of support rods 18. The telescopic movement of the hydraulic rod 15 is converted into the opposite or opposite movement of the lane-splitting baffle 9 and the lane-splitting baffle 10 through the slider 16 and the support rods 18.

[0039] The upper surface of the slider 16 is slidably connected to the positioning slide 17. The bottom surface of the positioning slide 17 near one end is fixedly connected to the upper surface of the fixed end of the hydraulic rod 15, and the positioning slide 17 is fixed to the top of the inner wall of the mounting bracket 7 to limit the movement trajectory of the slider 16.

[0040] Guide rods 19 are fixedly connected to the upper surfaces of lane divider 19 and lane divider 20. A transverse guide rail 8 is slidably connected to the top of the guide rods 19. The transverse guide rail 8 is fixedly connected to the top of the inner wall of the mounting frame 7 and is used to guide lane divider 19 and lane divider 20 to move smoothly in a straight line.

[0041] Both the first baffle 9 and the second baffle 10 have a separation cone 11 fixedly connected to one end. The separation cone 11 has a streamlined structure and is used to guide PET bottles into the separation area.

[0042] The working principle of the flexible sorting device of the automatic PET bottle packing machine will be explained in detail below.

[0043] like Figure 1-5 As shown, the flexible sorting device of this PET bottle automatic case packer achieves efficient sorting through the following coordinated operation:

[0044] Dynamic detection system

[0045] Photoelectric sensors 1 2 and 2 3, which are staggered on both sides of the conveyor belt 1, detect the position, spacing and conveying speed of the PET bottles in real time and transmit the data to the controller 4.

[0046] Industrial camera 5 acquires images of the arrangement of PET bottles on the conveyor belt, and controller 4 analyzes the bottle shape, arrangement pattern and lane position deviation through image processing algorithms.

[0047] Adaptive lane adjustment

[0048] The controller 4 calculates the required lane spacing based on the detection data, drives the hydraulic rod 15 to extend and retract, and drives the slider 16 to slide along the positioning slide 17.

[0049] The slider 16 pushes the first lane baffle 9 and the second lane baffle 10 to move towards or away from each other along the transverse guide rail 8 via the support rod 18, so as to realize the dynamic adjustment of the relative distance between the two (adjustment accuracy ±0.5mm).

[0050] The separating cones 11 at the front ends of the first and second channel baffles 9 and 10 guide the PET bottles smoothly into the channel area, avoiding bottle jamming.

[0051] Flexible contact design

[0052] The thickened baffle 13 is detachably connected to the magnetic slot 12 of the second baffle 10 via the magnetic protrusion 14. Its curved end provides cushioning when it contacts the PET bottle, reducing rigid collisions.

[0053] When the diameter of the PET bottle changes, the thickened baffle 13 of different thicknesses or materials can be quickly replaced (replacement time < 2 minutes).

[0054] Closed-loop control logic

[0055] The controller 4 dynamically adjusts the extension and retraction of the hydraulic rod 15 based on real-time feedback from the industrial camera 5, ensuring that the lane spacing is precisely matched with the diameter of the PET bottle and the packing specifications.

[0056] In high-speed conveying scenarios (>300 bottles / minute), the speed compensation algorithm of photoelectric sensor 1 and photoelectric sensor 2 synchronizes the movement rhythm of conveyor belt 1 and channel assembly 6 to avoid bottle accumulation or flow interruption.

[0057] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
