Description

Technical Field

[0001] This invention relates to the field of flexible tube packaging production technology, and more specifically, to a packaging flexible tube sorting and feeding device and method. Background Technology

[0002] In existing technologies, packaging tubes are widely used in cosmetics, pharmaceuticals, food and other fields due to their advantages such as being lightweight, having good sealing performance, and being easy to squeeze and use. In the production and processing of packaging tubes, after the raw tube is processed by a single-end injection molding process, it will form a structure with one end open and the other end with a threaded head with a sealing function. This structure is the basic form for subsequent filling and capping processes. After collection and transportation, it needs to be processed by printing and other processes. The packaging tube needs to be put on the vertical bar of the conveyor belt. When placing it, the open end should be facing down and the threaded head should be facing up when putting it on the vertical bar. However, at present, the operation of loading and putting the packaging tubes on the vertical bar in the industry is still mainly done manually. The speed of the single-process operation of manual sorting, orientation and putting on the vertical bar is limited, the production efficiency is low, the labor cost is high and the labor intensity is high. Therefore, a technical solution is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and to automatically sort and feed the tubing, providing a packaging tubing sorting and feeding device and method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention discloses a packaging hose sorting and feeding device, including a vibratory feeder, a feeding device, a first turntable, and a conveyor belt. The vibratory feeder transmits the hose to the feeding device, which includes a feeding hopper. The feeding hopper is equipped with a stop bar. The hose is fed to the upper end of the stop bar, and one threaded end of the hose falls downwards. The first turntable is equipped with multiple receiving cylinders. The threaded portion of the hose is inserted into the receiving cylinder. The rotation of the first turntable causes the receiving cylinder containing the hose to rotate half a revolution. The open end of the hose is fitted downwards onto the vertical bar of the conveyor belt.

[0006] Furthermore, the vibratory feeder includes a discharge end, the feeding device includes a housing, the housing includes the feeding hopper and a connecting plate, the connecting plate is connected to the discharge end, the length direction of the hose is perpendicular to the conveying direction of the hose, and the width of the connecting plate corresponds to the length of the hose.

[0007] Furthermore, the feeding hopper includes a converging part and a discharge port. The converging part is located below the feeding hopper, and the diameter of the converging part gradually decreases from top to bottom. The discharge port is located below the converging part, and the diameter of the discharge port gradually decreases from top to bottom. The lower opening diameter of the discharge port corresponds to the outer diameter of the flexible hose.

[0008] Furthermore, the stop bar is fixedly installed in the hopper, the stop bar is located in the middle of the hopper, the length direction of the stop bar is parallel to the conveying direction of the hose, the stop bar includes an end and an inclined surface, the end is located at the upper end of the stop bar, and there are two inclined surfaces, which are located on both sides of the end.

[0009] Furthermore, a partition plate is installed in the hopper, the partition plate is located below the stop bar, and the partition plate extends toward the discharge port of the hopper.

[0010] Furthermore, the feeding device includes a blocking device, which includes a first cylinder and a baffle. The baffle is located above the connection between the feeding hopper and the connecting plate. The baffle is driven to rise and fall by the first cylinder, and the baffle can prevent the hose from entering the feeding hopper.

[0011] Furthermore, it includes a limiting plate located on the outer periphery of the first turntable. The limiting plate is an arc plate and is concentrically arranged with the first turntable. When the first turntable rotates clockwise, the limiting plate is located in the lower right section of the first turntable.

[0012] Furthermore, a second turntable is included, located on one side of the first turntable. The second turntable is equipped with a rejection device, which includes a gripper and a second cylinder. The second cylinder controls the gripper to move closer to or away from the first turntable. The gripper is capable of gripping the threaded end of the hose. After the gripper grips the hose and removes it from the receiving cylinder, it can be placed on the vertical bar of the conveyor belt below.

[0013] Furthermore, including a first sensor and a second sensor, the first turntable is equipped with eight receiving cylinders, which are arranged at equal intervals around the rotation axis of the first turntable. The first sensor is located at the position after the receiving cylinder where the hose is placed. The first sensor includes a first sensing terminal and two second sensing terminals, which are located on both sides of the first sensing terminal. When the hose inside the receiving cylinder has its open end facing outward, both the first sensing terminal and the second sensing terminal are blocked. When the hose inside the receiving cylinder has its threaded end facing outward, the first sensing terminal is blocked. The second sensor is located at the position before the vertical rod where the hose is placed. When the second sensor is blocked, the hose is present on the vertical rod.

[0014] A method for sorting and feeding packaging tubes, based on the aforementioned packaging tube sorting and feeding device, includes the following steps:

[0015] S1: The hoses are arranged through the vibratory feeder and are conveyed in a direction perpendicular to their axis;

[0016] S2: When the hose reaches the hopper of the feeding device, the end of the hose tilts downward and falls due to the division of the baffle in the hopper;

[0017] S3: The hose is vertically fed out through the discharge port of the hopper. The lower end of the hose is inserted into the receiving cylinder at the upper end of the first turntable. After the first turntable rotates 180°, the hose falls and is looped onto the vertical bar of the conveyor belt below.

[0018] If the threaded end of the hose inserted into the receiving cylinder faces outward, the rejection device will be triggered. When it rotates to 90°, it will be gripped by the claws of the rejection device and pulled out of the receiving cylinder. After the claws retract, it will rotate 90° and place the rejected hose with the open end facing down on the vertical bar of the conveyor belt.

[0019] The beneficial effects of this invention are:

[0020] 1. This invention sets a baffle in the hopper and adapts the baffle's inclined surface to the weight difference of the hose to achieve initial orientation without additional power. Combined with a sensing detection and rejection device, it completes the entire process of automating the rod from disorder to orientation.

[0021] 2. In this invention, the second turntable, the first sensor, and the second sensor work together to remove and adjust the hose after it falls in the opposite direction, which has better orientation accuracy and excellent feeding stability. Attached Figure Description

[0028] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1-5 As shown, this embodiment discloses a packaging hose sorting and feeding device, including a vibratory feeder 1, a feeding device 2, a first turntable 3, a second turntable 4, a first sensor 5, a conveyor belt 6, a limiting plate 7, and a second sensor 8. The vibratory feeder 1 adopts a conventional spiral vibration feeding structure. The discharge end 11 of the vibratory feeder 1 is fixedly connected to the connecting plate 212 of the feeding device 2. The vibratory feeder 1 arranges the disordered hoses 101 into a horizontal posture through vibration, with the length direction perpendicular to the conveying direction, and continuously conveys them to the feeding device 2. The width of the connecting plate 212 is adapted to the length of the hose 101. The width of the connecting plate 212 is slightly larger than the length of the hose 101 to ensure that the hose 101 is conveyed smoothly. The vibratory feeder 1 transmits the hose 101 to the feeding device 2.

[0030] The feeding device 2 includes a housing 21, a baffle 22, and a partition plate 23. The housing 21 is integrally formed from a feeding hopper 211 and a connecting plate 212. The upper part of the feeding hopper 211 is an open structure, and the lower part of the feeding hopper 211 includes a gathering part 2111 and a discharge port 2112. The diameter of the gathering part 2111 gradually decreases from top to bottom, and the internal width of the gathering part 2111 gradually narrows towards the discharge port 2112, so that the falling hose 101 is guided to the discharge port 2112. The discharge port 2112 is located below the gathering part 2111, and the diameter of the discharge port 2112 gradually decreases from top to bottom. The lower opening diameter of the discharge port 2112 corresponds to the outer diameter of the hose 101. The gathering part 2111 realizes the initial gathering of the hose 101, and the discharge port 2112 further calibrates the posture of the hose 101 to ensure that the hose 101 falls vertically into the receiving cylinder 31.

[0031] The stop bar 22 is bolted to the feed hopper 211. The stop bar 22 is located in the middle of the feed hopper 211, and its length is parallel to the conveying direction of the hose 101. The stop bar 22 includes an end 221 and inclined surfaces 222. The end 221 is located at the upper end of the stop bar 22. Two inclined surfaces 222 are provided, located on either side of the end 221. The end 221 is located at the upper end of the stop bar 22, and its upper end is flush with the inner bottom surface of the connecting plate 212, allowing for connection between the connecting plate 212 and the stop bar 22. The end 221 adopts a rounded arc design to avoid scratching the surface of the hose 101. The threaded head 1012 of the tube 101 is injection molded. The weight difference between the threaded head 1012 and the open end 1011 is as follows: taking the center of the length of the hose 101 as the boundary, the threaded head 1012 is 5%-15% heavier than the open end 1011. This causes the threaded head 1012 to tilt downwards first and fall down, achieving passive initial orientation. Compared with the existing orientation mechanism that requires additional power, the structure is simpler and the energy consumption is lower. The inclined design of the stop bar 22 can allow the hose 101 to tilt at a larger angle in the initial tilting and falling, preventing the hose 101 from getting stuck between the inner wall of the hopper 211 and the stop bar 22, making the descent of the hose 101 smoother.

[0032] A partition plate 23 is fixedly installed inside the hopper 211. The partition plate 23 is located below the baffle 22 and extends toward the discharge port 2112 of the hopper 211. The partition plate 23 can divide the space below the baffle 22 into two areas, reducing the space size of the hose 101 during the falling process and preventing the elastic hose 101 from hitting the inner wall of the hopper 211 and reversing during the falling process.

[0033] The feeding device 2 also includes a blocking device 24, which includes a first cylinder 241 and a baffle 242. The baffle 242 is located above the connection between the feeding hopper 211 and the connecting plate 212. The baffle 242 is driven to rise and fall by the first cylinder 241. The baffle 242 can block the hose 101 from entering the feeding hopper 211. The frequency of the hose 101 entering the feeding hopper 211 is controlled by the rising and falling of the baffle 242, which is adapted to the rotation rhythm of the first turntable 3, so that the hose 101 is fed one by one, avoiding the hose 101 from being fed too fast and causing jamming.

[0034] The first turntable 3 is located below the discharge port 2112 and is driven to rotate by a stepper motor with adjustable speed. The first turntable 3 is equipped with eight receiving cylinders 31, which are arranged at equal intervals around the first turntable 3. The distance between two adjacent receiving cylinders 31 is 45°. The depth of the receiving cylinder 31 is greater than half the length of the hose 101, and the inner diameter of the receiving cylinder 31 is slightly larger than the outer diameter of the hose 101, so that the hose 101 can be mostly inserted into the receiving cylinder 31, making the rotation and transfer more stable and preventing the hose 101 from detaching from the receiving cylinder 31 when the first turntable 3 rotates. The limiting plate 7 is located on the outer periphery of the first turntable 3. The limiting plate 7 is an arc plate and is concentrically set with the first turntable 3. When the first turntable 3 rotates clockwise, the limiting plate 7 is located in the lower right section of the first turntable 3 to limit the hose 101 during the rotation process, preventing the hose 101 from falling off during the rotation from 90° to 180° and ensuring the stability of the hose 101's posture.

[0035] Under normal circumstances, the threaded end 1012 of the hose 101 is inserted into the receiving cylinder 31 with the thread facing downward. The rotation of the first turntable 3 causes the receiving cylinder 31 containing the hose 101 to rotate half a turn. The open end 1011 of the hose 101 is then placed on the vertical rod 61 of the conveyor belt 6 with the thread facing downward, thus completing the sorting and feeding of the hose 101. When the weight difference between the threaded end 1012 and the open end 1011 of the hose 101 is small, the open end 1011 of the hose 101 may occasionally fall downward. In this embodiment, the second turntable 4, the first sensor 5, and the second sensor 8 are used to remove and adjust the hose 101 after it falls in the opposite direction.

[0036] The second turntable 4 is located to one side of the first turntable 3. When the first turntable 3 rotates clockwise, the second turntable 4 is located to the right of the first turntable 3. The second turntable 4 is equipped with a rejection device 41, which includes a gripper 42 and a second cylinder 43. The second cylinder 43 controls the gripper 42 to move closer to or away from the first turntable 3. The gripper 42 is a finger cylinder and includes two clamps 421 that can move closer to or away from each other. The clamps 421 can clamp the threaded head 1012 of the hose 101. The inner wall of 1 is provided with a soft rubber pad to avoid damaging the threaded head 1012. After the gripper 42 clamps the hose 101, the second cylinder 43 drives the gripper 42 away from the first turntable 3. After the clamped hose 101 is separated from the receiving cylinder 31, the second turntable 4 rotates counterclockwise. The second cylinder 43 extends to place the hose 101 on the vertical bar 61 of the conveyor belt 6 below. The rejection device 41 corrects the hose 101 with incorrect orientation to ensure that the hose 101 is finally in the position of the open end 1011 facing down.

[0037] Both the first sensor 5 and the second sensor 8 are photoelectric sensors. The first sensor 5 is located at the next station after the receiving cylinder 31 where the flexible hose 101 is placed, corresponding to the second station of the receiving cylinder 31 on the first turntable 3, and is 135° away from the unloading station. The first sensor 5 includes a first sensing terminal 51 and two second sensing terminals 52. The two second sensing terminals 52 are located on both sides of the first sensing terminal 51, and the first sensing terminal 51 is located in the middle. When the flexible hose 101 inside the receiving cylinder 31 is at the open end 1... When 011 is facing outwards, both the first sensing terminal 51 and the second sensing terminal 52 are blocked, and the rejection device 41 will not be triggered. When the threaded head 101 of the hose 101 in the receiving cylinder 31 is facing outwards, the first sensing terminal 51 is blocked by the threaded head 1012, and the two second sensing terminals 52 are not blocked. At this time, the rejection device 41 will be triggered. When the hose 101 at this station rotates another 45° to the 90° station, the gripper 42 of the rejection device 41 will extend and remove the hose 101.

[0038] The conveyor belt 6 is a chain plate type conveyor belt. Vertical rods 61 are evenly distributed on the conveyor belt 6. The inner diameter of the vertical rods 61 is adapted to the opening end 1011 of the hose 101. The second sensor 8 is located at the station before the vertical rod 61 where the hose 101 is placed. When the first turntable 3 rotates clockwise, the conveyor belt 6 conveys from right to left. When the second sensor 8 is blocked, the vertical rod 61 has the hose 101. The sensor detects whether the vertical rod 61 already has the hose 101 to avoid duplicate rod placement.

[0039] This embodiment also provides a method for sorting and feeding packaging tubes, based on the aforementioned packaging tube sorting and feeding device, including the following steps:

[0040] S1: Pour the single-head injection molded hose 101 into the vibratory plate 1. The hose 101 is arranged through the vibratory plate 1 and conveyed to the connecting plate 212 of the feeding device 2 along a direction perpendicular to its axis.

[0041] S2: When the hose 101 reaches the hopper 211 of the feeding device 2, the baffle 242 of the blocking device 24 raises and lowers to control the hose 101 to enter the hopper 211 one by one. Since the baffle 22 in the hopper 211 splits the hose 101 in the middle, the heavier end of the hose 101 tilts downward and falls.

[0042] S3: The hose 101 is vertically fed out through the discharge port 2112 of the hopper 211. The lower end of the hose 101 is inserted into the upper receiving cylinder 31 of the first turntable 3. If the open end 1011 of the hose 101 inserted into the receiving cylinder 31 faces outward, the hose 101 falls down and is fitted onto the vertical rod 61 of the conveyor belt 6 located below after the first turntable 3 rotates 180°.

[0043] If the threaded end 1012 of the hose 101 inserted into the receiving cylinder 31 faces outward, the rejection device 41 will be triggered. When rotated to 90°, the rejection device 41 will be gripped by the jaws 42 and pulled out of the receiving cylinder 31. After the jaws 42 are retracted, rotate 90° and place the rejected hose 101 with the open end 1011 facing down on the vertical bar 61 of the conveyor belt 6.

[0044] The second sensor 8 detects the status of the vertical rod 61 in real time. If it detects that the vertical rod 61 is equipped with a hose 101, the PLC controller pauses the feeding action of the corresponding station, and the conveyor belt 6 continues to run, so that the vertical rod 61 with the hose 101 is skipped over the hose 101 of the first turntable 3 and placed forward for conveying.

[0045] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
