The invention includes a light-shielding plate with an arc-shaped plate. The push rod detection photoelectric sensor is located between adjacent light-shielding plates. The light-shielding plate blocks external light. Simultaneously, the light-shielding plate, driven by an electric rotating shaft, drives the detection photoelectric sensor to rotate back and forth.

In addition, the arc-shaped plate is located around the outer ring of the detection photoelectric sensor. When the device is in the standard position, the detection photoelectric sensor cannot see the arc-shaped plate. When the detection photoelectric sensor deviates during its back-and-forth movement, it can see the arc-shaped plate, which serves as a position calibration tool.

Description

Its stable operation directly determines production efficiency and product quality. The photoelectric detection device is used to detect missing or malfunctioning pushers. The core principle of the photoelectric detection device is to emit light of a specific wavelength and receive the signal light reflected by the pusher bar to determine the position and status of the pusher bar.

[0003] Chinese Patent Publication No. CN208140570U discloses a high-precision photoelectric detection device, which relates to the field of photoelectric detection technology. Two photoelectric transmitters each have a light-isolating channel I installed at their front ends. Inside each of the two transmitters are a light source, a first lens, and a second lens, respectively. The first and second lenses are respectively positioned on the right side of the light source.

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0021] According to one embodiment of the present invention, Figures 1 to 9 As shown.

[0022] Existing intelligent detection devices for collating machine push rods based on photoelectric detection are extremely sensitive to interference from external light. External light includes lighting of varying power within the workshop, natural light coming through windows, and reflected light from adjacent equipment. When external light enters the detection photocell, it easily forms light spots on the surface of the photosensitive element, internal lens, or surrounding structure. The intensity and angle of this reflected light vary irregularly, disrupting the original light signal of the detection device. The core working logic of the photocell is to achieve accurate identification by receiving light signals of specific wavelengths and intensities reflected from the push rod. Under normal operating conditions, the light signal reflected from the push rod has stable intensity and angular characteristics, allowing the detection device to identify these characteristics. The device accurately determines the position and state of the collating machine's push rod; however, reflected light can cause the detection device to have difficulty accurately identifying the push rod, leading to detection failure or misjudgment. To solve this problem, this invention incorporates the following design into an intelligent detection device for the collating machine's push rod based on photoelectric detection: An intelligent detection device for the collating machine's push rod based on photoelectric detection includes: a main body 1, a mounting plate 2 fixedly connected inside the main body 1, and a photoelectric detector 3 fixedly connected to the top of the mounting plate 2. The photoelectric detector 3 utilizes the photoelectric conversion principle to detect the existence, position, state, and characteristics of a target object through the transmission, reception, and analysis of light signals. The detection equipment typically consists of a light emitting device, a light receiving device, a signal processing circuit, and an output unit. A device cable 4 is fixedly connected to the side of the photoelectric detector 3. One end of the device cable 4 is fixedly connected to a book pusher detection photoelectric eye 5. The book pusher detection photoelectric eye 5 is the core component of the intelligent detection device for the book pusher of the collating machine, responsible for the transmission and reception of light signals. It is specifically used to accurately identify the position, state, and movement trajectory of the book pusher. An upper light-shielding plate 6 is fixedly connected to the top of the book pusher detection photoelectric eye 5, and an upper arc-shaped plate 7 is fixedly connected to the inner wall of the upper light-shielding plate 6. A lower light-shielding plate 8 is fixedly connected to the bottom of the book pusher detection photoelectric eye 5, and a lower arc-shaped plate 9 is fixedly connected to the inner wall of the lower light-shielding plate 8. An electric rotating shaft 10 is fixedly connected to the side of the lower light-shielding plate 8. Shaft 10 is a mechanical transmission component driven by a motor, capable of precise angular rotation or reciprocating motion. In the book pusher detection device of the collating machine, it is the core power unit for controlling the dynamic adjustment of the positions of components such as the light shield and the curved plate. One end of the electric rotating shaft 10 is movably connected to a movable frame 11, and the top of the movable frame 11 is fixedly connected to an electric telescopic rod 25. The electric telescopic rod 25 is a mechanical actuator driven by a motor, capable of linear reciprocating telescopic motion, and is widely used in automated equipment. Its core function is to push or pull the load through precise length changes to achieve automated control of extension, retraction, and positioning. The bottom of the movable frame 11 is fixedly connected to a device telescopic rod 24. The surfaces of the upper curved plate 7 and the lower curved plate 9 are both coated with black paint.Black paint has light-absorbing properties, absorbing external light that shines on the curved plate surface, preventing the curved plate from becoming a new source of interference due to reflection, and preventing reflected light from entering the optical path of the detection photoelectric sensor and the book pusher. Black paint also enhances light-blocking and anti-reflection capabilities, which helps reduce optical interference. The upper curved plate 7 and the lower curved plate 9 are symmetrically arranged about the horizontal central axis of the book pusher detection photoelectric sensor 5. The electric rotating shaft 10 is fixedly connected to the upper light-blocking plate 6. A pair of electric rotating shafts 10 are symmetrically arranged about the vertical central axis of the upper light-blocking plate 6. The electric telescopic rod 25 is fixedly connected to the intelligent detection device body 1 of the collating machine book pusher, and the device telescopic rod 24 is fixedly connected to the intelligent detection device body 1 of the collating machine book pusher.

[0023] When in use, the intelligent detection device 1 of the collating machine push rod is installed in the push rod area of ​​the collating machine, so that the push rod detection photoelectric eye 5 is facing the push rod. The collating machine is an automated device used in the printing and binding industry to automatically stack and arrange single sheets of paper with different page numbers and contents in a preset order. Its core function is to replace the tedious process of manual pagination and paper stacking, realize the rapid combination of multi-page documents, and provide neat and orderly book blocks for subsequent binding. The push rod is used to smoothly push the stacked book blocks from the stacking area to the conveyor track or the next device. When the detection device detects the push rod, the electric rotating shaft 10 starts to rotate clockwise, driving the upper light shield 6 and the lower light shield 8 to rotate upward. At the same time, the electric telescopic rod 25 starts to retract, and the device telescopic rod 24 starts to extend, causing the upper light shield 6 and the lower light shield 8 to rotate upward and move upward at the same time. When the light-shielding plate 8 is at the top, the electric rotating shaft 10 begins to rotate counterclockwise, causing the upper light-shielding plate 6 and the lower light-shielding plate 8 to rotate downwards. The electric telescopic rod 25 begins to extend, and the device telescopic rod 24 begins to retract, causing the upper light-shielding plate 6 and the lower light-shielding plate 8 to rotate and move downwards simultaneously. When the upper light-shielding plate 6 and the lower light-shielding plate 8 are at the bottom, the device begins to reset, allowing the push rod detection photoelectric sensor 5 to return to its initial position. The upper arc plate 7 and the lower arc plate 9 are located on both sides of the push rod detection photoelectric sensor 5, at the edge of the push rod detection photoelectric sensor 5. Throughout the detection process, the upper arc plate 7 and the lower arc plate 9 are not within the recognition area of ​​the push rod detection photoelectric sensor 5. With the reciprocating rotation of the push rod detection photoelectric sensor 5, if the upper arc plate 7 and the lower arc plate 9 appear in the detection area of ​​the push rod detection photoelectric sensor 5, it indicates that the device has shifted during the operation and the position of the device needs to be calibrated.

[0024] A light-shielding plate with an arc shape is installed, and the photoelectric sensor 5 for the book pusher is located between adjacent light-shielding plates. The light-shielding plate serves to block external light. Simultaneously, the light-shielding plate, driven by the electric rotating shaft 10, rotates the photoelectric sensor back and forth, changing the sensor's recognition position. The surface of the light-shielding plate has a matte black coating, which effectively absorbs stray light from all directions, including direct light from the workshop ceiling lights, natural light from windows, and reflected light generated during equipment operation. This creates a relatively stable optical environment for the photoelectric sensor, ensuring it can focus on capturing the effective signal reflected by the book pusher. Additionally, an electric telescopic rod 25 is installed at the top of the light-shielding plate. When the light-shielding plate rotates upwards, the electric telescopic rod 25 retracts, carrying... The rising of the light-shielding plate effectively expands the recognition range of the detection photoelectric sensor. In addition, the curved plate is located on the outer ring of the detection photoelectric sensor. When the device is in the standard position, the curved plate cannot be seen through the detection photoelectric sensor, which means that the position of the detection photoelectric sensor is accurate and the book pusher detection can be performed normally. When the detection photoelectric sensor deviates due to mechanical wear, dust accumulation or external vibration during its reciprocating motion, its optical axis will deviate from the preset direction. At this time, the detection photoelectric sensor can capture the reflected signal of the curved plate. Since the surface of the curved plate has specific reflective characteristics and position marks, the detection device can accurately determine the direction and amount of the deviation of the detection photoelectric sensor by analyzing these signals and promptly feed back to the control system. At this time, the curved plate can play a role in position calibration.

[0025] Existing intelligent detection devices for collating machine push rods based on photoelectric detection are problematic because collating machines often operate in printing and binding workshops, environments inherently containing large amounts of suspended particulate matter. Furthermore, paper processing generates paper dust and lint, which easily float in the air, creating continuous dust pollution. These suspended particles adhere to the core area of ​​the detection device. If particles adhere to the photoelectric sensor, the light intensity of the transmitting lens is attenuated due to obstruction. The light beam that should accurately illuminate the push rod surface becomes dim and scattered, resulting in a significant decrease in the intensity of the signal light reflected back from the push rod. The receiving lens, also obstructed by particles, cannot effectively capture the reflected light and may even misinterpret stray light scattered by particles as a valid signal. Additionally, particles adhere to the surfaces of the light-shielding plate and the curved plate, affecting the device's detection accuracy and leading to misjudgments. To address this issue, this invention incorporates the following design into the intelligent detection device for collating machine push rods based on photoelectric detection:

[0026] A first air duct 26 is fixedly connected to one side of the movable frame 11. A first fan 12 is fixedly connected to the side of the first air duct 26. A first gear 13 is fixedly connected inside the first fan 12, and a first rack 14 meshes with the side of the first gear 13. A second air duct 18 is fixedly connected to the other side of the movable frame 11. The first and second air ducts 26 and 18 provide a path for air delivery. A second fan 15 is fixedly connected to the side of the second air duct 18. The first and second fans 12 and 15 drive the airflow. A second gear 16 is fixedly connected inside the second fan 15, and a second rack 17 meshes with the side of the second gear 16. The first rack 14 and the intelligent detection device body 1 of the collating machine push rod are fixedly connected. The second rack 17 and the intelligent detection device body 1 of the collating machine push rod are fixedly connected. The second air duct 18 is fixedly connected to the other side of the first air duct. There is a fixed vertical plate 19, and a fixed horizontal plate 20 is set on the side of the fixed vertical plate 19. The fixed horizontal plate 20 is fixedly connected to the No. 2 air duct circulation pipe 18. Both the fixed vertical plate 19 and the fixed horizontal plate 20 are set at an angle and are staggered. The top of the photoelectric detector 3 is fixedly connected to the warning wire 21, and the top of the warning wire 21 is fixedly connected to the light warning device 22. The light warning device 22 is an electronic device that transmits specific information through light emission signals. It is widely used in industrial machinery, automation systems, public facilities and other scenarios. Its core function is to use the strong recognition of visual signals to quickly attract the attention of operators or monitoring personnel and ensure the timeliness and accuracy of information transmission. The light warning device 22 is fixedly connected to the intelligent detection device body 1 of the collating machine push rod. The bottom of the photoelectric detector 3 is fixedly connected to the collating machine wire 23, and the collating machine wire 23 is fixedly connected to the controller of the collating machine.

[0027] When the device is in use, when the movable frame 11 rises, it drives the first fan 12 and the second fan 15 to rise as well. At this time, the first gear 13 and the second gear 16 begin to rise, while the first rack 14 and the second rack 17 remain stationary. The first gear 13 and the second gear 16 then begin to rotate, driving the first fan 12 and the second fan 15 to rotate together. At this time, the first fan 12 draws in air, and the second fan 15 exhausts air, creating an airflow channel from the first fan 12 to the second fan 15. When the movable frame 11 descends, it drives the first fan 12 and the second fan 15 to descend as well. At this time, the first fan 12 exhausts air, and the second fan 15 draws in air, creating an airflow channel from the second fan 15 to the first fan 12. This airflow structure cleans the dust and particulate matter inside the device, ensuring its cleanliness and effectively preventing dust and particulate matter from adhering to the inside of the device and affecting its detection performance. When the push rod detects that the photoelectric sensor 5 does not recognize... When the pusher lever is not detected, the pusher lever detection photoelectric sensor 5 transmits a signal to the photoelectric detector 3. The photoelectric detector 3 then triggers the light warning device 22 to illuminate via the warning wire 21, thus alerting the staff. Simultaneously, the photoelectric detector 3 controls the collating machine to stop operating via the collating machine wire 23. This design creates a robust safety barrier for the stable operation of the collating machine. The machine automatically stops when one pusher lever is missing, eliminating various production failures caused by pusher lever malfunctions at their source. From a production efficiency perspective, this detection device effectively avoids downtime for troubleshooting equipment failures, ensuring the efficient and continuous operation of the production line. In terms of product quality control, it completely eliminates misaligned pages, product defects, and even scrap caused by pusher lever problems, saving the company significant production costs. From an operational safety perspective, it provides early warning and prevents potential risks from equipment malfunctions, comprehensively protecting the personal safety of operators.

[0028] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
