Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 4 As shown, the bamboo tableware flipping detection and conveying device proposed in this embodiment includes two belt conveyors 100 of different heights, and the same flipping mechanism is installed between the frames of the two belt conveyors 100. The flipping mechanism includes: The fixed frame 2 is fixedly connected between the frames of the two belt conveyors 100. Two support rods 201 are fixedly connected to both sides of its top, with the support rod 201 on the left side being higher than the support rod 201 on the right side. PLC controller 202 is fixedly connected to the top of the mounting bracket 2; The U-shaped guide plate 1 is inclined and fixedly connected to the top of four support rods 201. Two rectangular through holes 102 are opened on the right side of the bottom inner wall of the U-shaped guide plate 1. The U-shaped guide plate 1 is used to guide the bamboo tableware to slide to the right and downward when the belt conveyor 100 on the left conveys the bamboo tableware after one side has been inspected to the right. The laser emitting sensor 203 and the laser receiving sensor 204 are respectively embedded and fixed on the right side of the rear inner wall and the right side of the front inner wall of the U-shaped guide plate 1, and are both electrically connected to the PLC controller 202. An arc-shaped stop 101 is fixedly connected to the right side of the bottom inner wall of the U-shaped guide plate 1; the arc-shaped stop 101 is used to block and limit the bamboo tableware when it slides to the lower right inside the U-shaped guide plate 1; the laser receiving sensor 204 is used to receive the infrared signal emitted by the laser emitting sensor 203, and outputs the opposite signal to the PLC controller 202 when the bamboo tableware slides to the lower right and blocks the laser; when the PLC controller 202 detects this "signal change", it executes the corresponding "start-up" program. U-shaped support plate 3 is fixedly connected to the bottom of U-shaped guide plate 1; Solenoid valve 301 is fixedly connected to the left side of U-shaped support plate 3 and electrically connected to PLC controller 202. Its left end is connected to a fixed air pipe connector 302 for connecting to the air supply line of an external air compressor. The solenoid valve 301 is used to control the opening of solenoid valve 301 when PLC controller 202 executes the corresponding program, so that the external air compressor can supply high-pressure gas through solenoid valve 301. The telescopic ventilator is fixed to the right end of the solenoid valve 301 and located in the two rectangular through holes 102. The telescopic ventilator is used to blow high pressure on the left side of the bottom of the bamboo tableware that is blocked by the limit when the solenoid valve 301 is opened and high pressure gas is supplied, so that it tilts to the right and is conveyed to the belt conveyor 100 on the right side to be transported to the subsequent testing equipment for further testing. The distance control horizontal drive adjustment component is installed on the U-shaped support plate 3 and the telescopic ventilation blowing and turning component, and is electrically connected to the PLC controller 202; the distance control horizontal drive adjustment component is used to adjust the horizontal drive of the telescopic ventilation blowing and turning component according to different specifications of bamboo tableware when the PLC controller 202 is operated by personnel. In this embodiment, the bottom left and bottom right sides of the U-shaped guide plate 1 are both set as inclined surfaces. The high position of the left side of the bottom inner wall of the U-shaped guide plate 1 matches the right side of the left belt conveyor 100. The right side of the bottom inner wall of the U-shaped guide plate 1 is located above and to the left of the right belt conveyor 100 and matches it. The front inner wall and the rear inner wall of the U-shaped guide plate 1 are both provided with mounting holes, and the laser emitting sensor 203 and the laser receiving sensor 204 are respectively glued and fixed in the corresponding mounting holes.

[0017] Furthermore, such as Figure 1 , 2 As shown in Figure 4, the telescopic ventilation upward blowing and turning assembly includes an inner tube 303, an outer tube 304, a circular tube 305, and two high-pressure nozzles 306. The inner tube 303 is connected and fixed to the right end of the solenoid valve 301. The outer tube 304 is sealed and slidably sleeved on the inner tube 303. The U-shaped support plate 3 is slidably sleeved on the outer tube 304. The right end of the outer tube 304 is connected and fixed to the left side of the circular tube 305. The front and rear ends of the circular tube 305 are both set as sealing structures. The two high-pressure nozzles 306 are both connected and fixed to the top of the circular tube 305. The two high-pressure nozzles 306 are respectively located in the corresponding rectangular perforations 102 and do not contact their inner walls. In this embodiment, a sealing sleeve is bonded to the inner side of the outer tube 304, and the inner side of the sealing sleeve slides and contacts the outer side of the inner tube 303, so as to achieve the effect of sliding and sealing the inner side of the outer tube 304 and the outer side of the inner tube 303; a transverse guide hole is opened on the inner wall of the right side of the U-shaped support plate 3 to slide and fit with the outer side of the outer tube 304, so as to allow the outer tube 304 to pass through and guide its transverse sliding. In this implementation scheme, through the cooperation of the inner pipe 303, outer pipe 304, circular pipe 305, and two high-pressure nozzles 306, when the solenoid valve 301 is opened to supply high-pressure gas from the external air compressor, the high-pressure gas is sequentially supplied into the circular pipe 305 through the inner pipe 303 and outer pipe 304, and then sprayed upwards through the two high-pressure nozzles 306 to blow high pressure onto the left side of the bottom of the bamboo tableware. The high-pressure blowing force flips the tableware to the right, causing it to tilt onto the right-side conveyor belt 100 and be transported to the subsequent testing equipment for further testing. When the bamboo tableware is flipped onto the right-side conveyor belt 100, the laser receiver transmits... When the sensor 204 and the laser emitting sensor 203 are separated and the obstruction is removed, the laser emitting sensor 203 receives the corresponding laser infrared signal emitted by the laser receiving sensor 204 again and converts it into an initial signal, which is then transmitted to the PLC controller 202. At this time, the PLC controller 202 controls the solenoid valve 301 to close, stopping the high-pressure gas supply. When the obstruction is removed again, the blowing and flipping operation will continue. This process is repeated to achieve the effect of conveying and automatically flipping bamboo tableware. This makes it convenient to flip and convey one side after the previous one is inspected to the subsequent inspection equipment to inspect the other side, without the need for manual operation of flipping, thus saving labor costs.

[0018] Furthermore, such as Figure 1 , 2 As shown in Figure 4, the distance control lateral drive adjustment assembly includes an electric telescopic rod 401, a connecting seat 4, a reference plate 402, and a laser rangefinder 403. The electric telescopic rod 401 is fixedly installed on the bottom left side of the U-shaped support plate 3. The connecting seat 4 is fixedly connected between the extended end of the electric telescopic rod 401 and the bottom of the outer tube 304. The reference plate 402 is glued and fixed on the right side of the connecting seat 4. The laser rangefinder 403 is located on the right side of the reference plate 402 and is fixedly connected to the bottom right side of the U-shaped support plate 3. Both the electric telescopic rod 401 and the laser rangefinder 403 are electrically connected to the PLC controller 202. In this embodiment, the distance between the reference plate 402 and the laser rangefinder 403 is the same as the distance between the high-pressure nozzle 306 and the arc-shaped baffle 101; In this implementation scheme, the electric telescopic rod 401, connecting seat 4, reference plate 402, and laser rangefinder 403 work together to adjust the lateral position of the high-pressure nozzle 306 according to the different diameter specifications of bamboo tableware. This is to prevent the nozzles from being misaligned and causing unstable blowing. The PLC controller 202 is used to pre-set the closing distance of the electric telescopic rod 401 based on the position requirements of the high-pressure nozzle 306 corresponding to different bamboo tableware. The PLC controller 202 then initiates the adjustment process, controlling the laser rangefinder 403 to open and the electric telescopic rod 401 to start accordingly. The electric telescopic rod 401 drives the connecting seat 4 to move laterally to the right, which in turn moves the reference plate 402 and the outer tube 304 laterally. The outer tube 304 drives the two high-pressure nozzles 306 to move laterally through the round tube 305. The laser range sensor 403 detects the distance between itself and the reference plate 402, converts it into a standard electrical signal, and transmits it to the PLC controller 202. The PLC controller 202 converts the received standard electrical signal into an actual distance value through analog-to-digital conversion. When the distance value reaches the preset value, the PLC controller 202 controls the electric telescopic rod 401 to automatically close, thereby achieving the effect of lateral distance control adjustment of the high-pressure nozzles 306. By adjusting the lateral distance of the high-pressure nozzles 306, the lateral position of the high-pressure nozzles 306 can be flexibly and accurately adjusted according to bamboo tableware of different diameters, so as to adapt to the flipping application of bamboo tableware of different specifications and improve applicability.

[0019] It should be noted that the PLC controller 202 is preferably a Siemens S7-200SMART programmable controller. This controller integrates an analog input module, which can directly receive the standard electrical signal output by the laser rangefinder 403 and use its own analog-to-digital conversion function to accurately convert the electrical signal into the actual distance value, ensuring the accuracy of data detection. The laser rangefinder 403 is preferably a JGWY3 type rangefinder sensor. The laser emission sensor 203 and the laser reception sensor 204 are preferably Panasonic CX-F100 laser penetration receiver group for belt conveyors. This device integrates the laser emission and reception modules with the signal amplification and processing circuit, supports NPN / PNP and push-pull outputs for belt conveyors, and is compatible with industrial control systems such as belt conveyor PLCs and microcontrollers. Some models also support analog outputs, such as 4-20mA and 0-10V for belt conveyors, to meet different application requirements. Regarding the connection between the solenoid valve 301 and the PLC controller 202, it is preferable to connect them directly via a relay and a flexible wire to form an electrical connection controlled by the PLC controller 202. This wire-connected control method is a conventional and mature known technology for controllers and will not be described in detail here. In addition, since the laser rangefinder 403 is a moving part, the flexible wire connecting it is conventionally designed with a certain bending length reserved to meet its displacement requirements. The electrical connection between the electric telescopic rod 401 and the PLC controller 202 is achieved through a wire and a servo driver. The servo driver is preferably a Siemens V90 servo driver, which is a commonly used driver for controlling motors and electric actuators in conjunction with Siemens programmable controllers, meeting the requirements of the programmable controller to directly control the electric telescopic rod 401.

[0020] It should be further explained that the belt conveyor 100 is a conventional belt conveyor structure, installed at the outlet or inlet of the corresponding testing equipment; it mainly consists of two drive wheels, a motor, a support frame, and a conveyor belt. The two drive wheels are rotatably mounted inside the support frame, and the conveyor belt is driven and connected to the two drive wheels. The motor is mounted on the support frame and is used to drive one of the drive wheels to rotate, thereby driving the conveyor belt to run. The conventional components of this belt conveyor structure are existing known technology, so they will not be described in detail.

[0021] The usage method of this embodiment is as follows: When using the bamboo tableware flipping detection and conveying device, the air pipe connector 302 is connected to the external air compressor supply line beforehand. When the belt conveyor 100 on the left conveys the bamboo tableware after one side has been detected to the right, the bamboo tableware enters the U-shaped guide plate 1 and slides to the lower right in an inclined state. When the bamboo tableware slides to the lower right in the U-shaped guide plate 1, the arc-shaped stop 101 blocks and limits its movement. The laser receiving sensor 204 is used to receive the infrared signal emitted by the laser emitting sensor 203, and when the bamboo tableware slides to the lower right and blocks the laser, it outputs a reverse signal to the PLC controller 202. When the PLC controller 202 detects this "signal change", it executes the corresponding "start operation". The program, controlled by the PLC controller 202 according to the built-in production programming, opens the solenoid valve 301 to allow the external air compressor to supply high-pressure gas through the solenoid valve 301. When the solenoid valve 301 opens and the external air compressor supplies high-pressure gas, the high-pressure gas is sequentially supplied into the circular pipe 305 through the inner pipe 303 and the outer pipe 304, and then sprayed upwards through two high-pressure nozzles 306 to blow high pressure onto the left side of the bottom of the bamboo tableware. The high-pressure blowing force blows the left side of the bottom of the tableware to the right, causing it to tilt to the right and onto the right-side belt conveyor 100, where it is transported to the subsequent testing equipment for further testing. When the bamboo tableware is flipped onto the right-side belt conveyor 100, the laser receiving sensor detects the gas. When the device 204 and the laser emitting sensor 203 are separated and the obstruction is removed, the laser emitting sensor 203 receives the corresponding laser infrared signal emitted by the laser receiving sensor 204 again and converts it into an initial signal, which is then transmitted to the PLC controller 202. At this time, the PLC controller 202 controls the solenoid valve 301 to close, stopping the high-pressure gas supply. When the obstruction is removed again, the blowing and flipping work will continue. This process is repeated to achieve the effect of conveying bamboo tableware and automatically and safely flipping it. This makes it convenient to flip and convey the tableware to the subsequent inspection equipment after one side is inspected. No manual operation is required to flip the tableware, saving time and effort, reducing labor costs, and meeting the needs of modern automated production. When it is necessary to adjust the lateral position of the high-pressure nozzles 306 according to the different diameter specifications of bamboo tableware to avoid misalignment and instability, the distance value for closing the electric telescopic rod 401 is preset using the PLC controller 202 according to the position requirements of the high-pressure nozzles 306 corresponding to different bamboo tableware. Operating the PLC controller 202 to start the adjustment process activates the laser rangefinder 403 and the electric telescopic rod 401 accordingly. The electric telescopic rod 401 drives the connecting seat 4 to move laterally to the right. The connecting seat 4 drives the reference plate 402 and the outer tube 304 to move laterally. The outer tube 304 drives the two high-pressure nozzles through the round tube 305. The laser rangefinder 403 detects the distance between itself and the reference plate 402, converts it into a standard electrical signal, and transmits it to the PLC controller 202. The PLC controller 202 converts the received standard electrical signal into an actual distance value through analog-to-digital conversion. When the distance value reaches the preset value, the PLC controller 202 controls the electric telescopic rod 401 to automatically close, thereby achieving the effect of lateral distance control adjustment of the high-pressure nozzle 306. Through the lateral distance control adjustment of the high-pressure nozzle 306, the lateral position of the high-pressure nozzle 306 can be flexibly and accurately adjusted according to bamboo tableware of different diameters, so as to adapt to the flipping application of bamboo tableware of different specifications and improve applicability.
