Description

Technical Field

[0001] This utility model relates to the field of bottle preform production technology, specifically to a sorting device for bottle preform production. Background Technology

[0002] During the production of preforms, rapid sorting of preforms is required. Chinese Patent No. CN 221183775 U discloses a sorting device for preform production, including a main body; a first motor drives gears in a gear set to rotate, allowing the preforms placed on a placement seat to rotate, facilitating comprehensive inspection of the preforms. An industrial camera can inspect multiple preforms simultaneously, reducing the workload of workers. If a preform detected by the industrial camera is defective, it transmits a signal to a controller, which removes the defective preform using a first electric telescopic rod, a second electric telescopic rod, and a mechanical gripper.

[0003] However, the above-mentioned publicly available solutions have the following shortcomings: When the sorting device is in use, the industrial camera does not have a high degree of continuity in detecting bottle preforms. After multiple sets of bottle preforms have been detected, the detection work needs to be paused, multiple sets of bottle preforms need to be removed, and new bottle preforms to be detected need to be placed. This causes the continuity of the entire production process to be interrupted, making it impossible to achieve fully automated production and making it difficult to improve production efficiency. Utility Model Content

The machine body is equipped with two sets of third conveyor belt mechanisms for angle adjustment, which are arranged perpendicularly to the first conveyor belt mechanism. It also includes a detection mechanism consisting of a detection frame mounted on the top of an electric turntable, a lifting frame that moves and adjusts along the height of the detection frame via a lifting mechanism, a detection component mounted on the lifting frame, and an extension frame mounted on the top of the detection frame. A second photoelectric sensor is mounted on the extension frame along the axial direction of the electric turntable, and a first photoelectric sensor is mounted on the extension frame at the end furthest from the detection frame. The detection end of the first photoelectric sensor corresponds to the output end of the first conveyor belt mechanism.

[0006] Preferably, the feeding mechanism consists of a first conveyor belt mechanism set in the first mounting groove and two sets of guide plates. The two sets of guide plates are driven by telescopic components to move closer to or further away from the horizontal direction of the machine body. The guide plates are distributed above the first conveyor belt mechanism.

[0007] Preferably, a plurality of auxiliary rollers are rotatably connected in the fourth mounting groove and at one end near the first conveyor belt mechanism, and the top of the outer peripheral surface of the auxiliary rollers is on the same horizontal plane as the top surface of the conveyor belt in the first conveyor belt mechanism.

[0014] Example 1, as Figures 1 to 3As shown, this utility model proposes a sorting device for bottle preform production, including a body 1, a sorting mechanism, and a detection mechanism. A first mounting groove 101 is provided inside the top of the body 1, and a feeding mechanism is provided in the first mounting groove 101. A second mounting groove 102 is provided at the output end of the first mounting groove 101 and located on the body 1. Two sets of third mounting grooves 103 are provided on both sides of the second mounting groove 102 and located on the body 1. The sorting mechanism is located in the second mounting groove 102 and consists of an electric turntable 3 located in the second mounting groove 102, a second conveyor belt mechanism 303 located on the electric turntable 3, and a third... The third conveyor belt mechanism 5 in the mounting slot 103 is used to adjust the angle of the electric turntable 3, which is driven by a drive mechanism in the second mounting slot 102. The drive mechanism consists of a servo motor and a reducer. The servo motor is started and controlled to rotate at a suitable angle by a controller. An angle encoder can be installed on the rotating shaft of the electric turntable 3 to monitor the rotation angle of the turntable in real time, ensuring that it returns to the initial position accurately upon reset. The structure of the second conveyor belt mechanism 303 is the same as that of the first conveyor belt mechanism 2, but the dimensions are different. The top surface of the conveyor belt in the second conveyor belt mechanism 303 is located at the same position as the top surface of the conveyor belt in the first conveyor belt mechanism 2. On the same horizontal plane, two sets of third conveyor belt mechanisms 5 are provided. The two sets of third conveyor belt mechanisms 5 are vertically arranged on the machine body 1 relative to the first conveyor belt mechanism 2. The structure of the third conveyor belt mechanism 5 is the same as that of the first conveyor belt mechanism 2, but the dimensions are different. The two sets of third conveyor belt mechanisms 5 correspond to the qualified bottle preform conveying line and the unqualified bottle preform conveying line, respectively. The detection mechanism consists of a detection frame 4 installed on the top of the electric turntable 3, a lifting frame 402 driven by a lifting mechanism to move and adjust along the height direction of the detection frame 4, a detection component 404 installed on the lifting frame 402, and an extension frame 405 installed on the top of the detection frame 4. The lifting mechanism is driven by a motor. The device consists of a threaded rod that is rotatably connected to the detection frame 4. The threaded rod is connected to the output end of the motor. The end of the lifting frame 402 away from the detection component 404 is threadedly connected to the threaded rod. The detection frame 4 has a guide opening 401 corresponding to the lifting frame 402. The lifting frame 402 slides and adjusts along the height direction of the guide opening 401. A second photoelectric sensor 407 is provided on the extension frame 405 and located in the axial direction of the electric turntable 3. A first photoelectric sensor 406 is provided on the extension frame 405 and located away from the detection frame 4. The detection end of the first photoelectric sensor 406 corresponds to the output end of the first conveyor belt mechanism 2.

[0015] Furthermore, the feeding mechanism consists of a first conveyor belt mechanism 2 disposed in the first mounting groove 101 and two sets of guide plates 201. The top surface of the conveyor belt in the first conveyor belt mechanism 2 protrudes from the first mounting groove 101. The two sets of guide plates 201 are driven by telescopic components to move closer to or further away from the machine body 1 in the horizontal direction. The telescopic components are hydraulic rods, and the two sets of hydraulic rods are controlled by a controller to move synchronously. The guide plates 201 are distributed above the first conveyor belt mechanism 2. The first conveyor belt mechanism 2 mainly consists of a large conveyor belt, a drive device, a tensioning device, idlers, and protective devices, which are existing technologies and will not be described in detail here.

[0016] Furthermore, multiple sets of auxiliary rollers 302 are rotatably connected in the fourth mounting groove 301 and at one end near the first conveyor belt mechanism 2. The top of the outer peripheral surface of the auxiliary rollers 302 is on the same horizontal plane as the top surface of the conveyor belt in the first conveyor belt mechanism 2, which facilitates the smooth transfer of the auxiliary preform to the second conveyor belt mechanism 303.

[0017] Furthermore, a pressure sensor is embedded on the guide plate 201 and on the end face that contacts the preform to monitor the clamping force of the two sets of guide plates 201 on the preform. This prevents the clamping force from being too large and interfering with the preform being conveyed on the first conveyor belt mechanism 2, or from being too small and causing the preform to tilt or fall over, thereby improving detection efficiency. A displacement sensor is also provided between the two sets of guide plates 201 to provide real-time feedback on the movement distance of the guide plates and improve the accuracy of the spacing adjustment.

[0018] In this embodiment, based on the size of the preform, the controller initiates the synchronous movement of two sets of telescopic components, thereby driving the two sets of guide plates 201 to approach each other at a suitable distance until the two sets of guide plates 201 contact the side wall of the preform but do not interfere with the first conveyor belt mechanism 2's conveying of the preform, preventing the preform from tilting or tipping over during transportation; when the first photoelectric sensor 406 detects that the preform at the output end of the first conveyor belt mechanism 2 has reached the designated position, it transmits the monitoring information to the controller, which then initiates the second conveyor belt mechanism 303 to receive a set of preforms at the output end of the first conveyor belt mechanism 2. When the second photoelectric sensor 407 detects that this set of preforms has reached the set position on the second conveyor belt mechanism 303, it pauses the operation of the first conveyor belt mechanism 2 and the second conveyor belt mechanism 303, and the controller initiates the lifting mechanism to drive the lifting frame 402 to move and adjust along the height direction of the guide opening 401, thereby... The detection component 404 detects the preforms and transmits the collected detection signals to the controller in real time. The controller has a built-in preset pass / fail threshold. By comparing the data with the threshold, the pass / fail status of the preforms is determined. When the detection data is qualified, the controller starts the electric turntable 3 to rotate 90 degrees, so that the output end of the second conveyor belt mechanism 303 rotates to the third conveyor belt mechanism 5 corresponding to the qualified preform conveying line. The qualified preforms are sorted away by starting the second conveyor belt mechanism 303 and the corresponding third conveyor belt mechanism 5. Then the electric turntable 3 is returned to the initial state to monitor the next set of preforms. When the preform monitoring result is unsuitable, the electric turntable 3 rotates the preform to the third conveyor belt mechanism 5 corresponding to the unqualified preform conveying line for conveying. When the detection component 404 detects preforms, it can replenish preforms in the first conveyor belt mechanism 2 in a timely manner to wait for detection, resulting in a high degree of detection continuity.

[0019] Example 2, as Figure 3 As shown, the sorting device for bottle preform production proposed in this utility model, compared with Embodiment 1, the lifting frame 402 is composed of an arc-shaped seat and a slide mounted on the arc-shaped seat. The slide is threadedly connected to the threaded rod in the lifting mechanism, and the slide is slidably connected to the guide port 401.

[0020] Furthermore, the detection assembly 404 is provided in two sets, and the two sets of detection assemblies 404 are installed at both ends of the arc-shaped seat. The detection assembly 404 consists of a mounting plate 403 installed at the end of the arc-shaped seat, an ultrasonic probe, an industrial camera and a laser distance sensor installed on the mounting plate 403.

[0021] In this embodiment, by setting the arc-shaped seat, two sets of detection components 404 can be set on the lifting frame 402 to facilitate comprehensive inspection of the bottle preform. The ultrasonic probe can detect defects such as bubbles and impurities on the bottle preform, the laser rangefinder can detect the size of the bottle preform, and the industrial camera can detect the appearance defects of the bottle preform, further improving the inspection efficiency and quality.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
