Abstract
Description
Technical Field
[0001] This application relates to the field of packaging machine technology, and in particular to a device for adjusting the skewness of packaging paper using a photoelectric sensor at the small package inlet of a fully automatic packaging machine. Background Technology
[0002] In the application of fully automatic packaging machines, proper alignment of the wrapping paper and stable book feeding are key factors in ensuring packaging quality and normal equipment operation. Currently, most fully automatic packaging machines are designed so that books enter the machine with their narrowest side when packaging long, narrow items. This design is primarily to ensure that the wrapping paper can smoothly wrap the book, reducing the risk of jamming due to size mismatch.
[0003] However, in actual operation, books may tilt or shift due to uneven conveyor belt speed, mechanical vibration, or uneven weight distribution within the books themselves. When books do not enter the packaging machine in the intended direction, especially with the widest side, the width of the wrapping paper may not be sufficient to completely cover the side of the book, resulting in incomplete packaging, or misalignment between the wrapping paper and the book may cause the machine to jam. Jamming not only affects production efficiency but may also damage the equipment, increasing maintenance costs and downtime.
[0004] Existing fully automatic packaging machines typically feature photoelectric sensors at the small package inlet to detect and adjust the position of the wrapping paper. However, this device has certain technical limitations when dealing with changes in the direction of book transport; it cannot effectively identify and correct wrapping paper misalignment caused by book skew. Especially when books enter with their wide edges, the photoelectric sensor system may fail to report abnormalities in time, leading to misalignment of the wrapping paper and potentially causing machine jams. Therefore, a photoelectric sensor at the small package inlet of a fully automatic packaging machine is proposed to adjust the skew of the wrapping paper. Summary of the Invention
[0005] To address the problem that existing photoelectric detection devices cannot effectively identify and correct packaging paper misalignment caused by book skew, this application provides a photoelectric device for adjusting packaging paper skew at the small package inlet of a fully automatic packaging machine.

A straightening motor is fixedly installed on the upper surface of the vertical frame, and the output end of the straightening motor is fixedly connected to a vertically set first electric push rod. The telescopic end of the first electric push rod is fixedly connected to a straightening seat, which is a rectangular frame with an opening on one side.

Detailed Implementation
[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] This application discloses a device for adjusting the skew of packaging paper at the inlet of a fully automatic packaging machine. The frame 1 is equipped with a conveying mechanism, through which the object is conveyed to the inlet of the packaging machine. It also includes a stand 5 fixedly installed in the middle of the upper surface of the frame 1. A straightening motor 6 is fixedly installed on the upper surface of the stand 5. The output end of the straightening motor 6 is fixedly connected to a vertically arranged first electric push rod 7. The telescopic end of the first electric push rod 7 is fixedly connected to a straightening seat 10. The straightening seat 10 is a rectangular frame with an opening on one side.
[0025] Furthermore, inclined plates 9 are fixedly connected to both sides of the inner surface of the frame 1. The near ends of the inclined plates 9 face the alignment seat 10, and the distance between the near ends of the inclined plates 9 is equal to the distance between the open ends of the alignment seat 10.
[0026] Furthermore, the conveying mechanism includes conveying rollers 4 rotatably mounted on both sides of the frame 1, with conveyor belts 2 sleeved on the outer surfaces of the two sets of conveying rollers 4, and a conveying motor 3 fixedly mounted on the outer surface of the frame 1. The output shaft of the conveying motor 3 passes through the frame 1 and is fixedly connected to one of the sets of conveying rollers 4.
[0027] Furthermore, a second electric push rod 8 is fixedly connected to both sides of the open end of the alignment seat 10, and an alignment plate 12 is fixedly connected to the telescopic end of the second electric push rod 8.
[0028] In this embodiment, starting the conveyor motor 3 drives the conveyor roller 4 and the conveyor belt 2 to move, thereby conveying the books. The conveying front end of the conveying mechanism is actually set at the output end of a production line on the books. Figure 4-5 As shown, the narrow side of the book is marked as a and the wide side as b. In the actual conveying process, due to mechanical vibration and other factors, the book is prone to shifting and the wide side of the book is facing the packaging machine inlet. In this application, by setting a straightening mechanism, the book can be straightened and the book can be ensured to enter the packaging machine with the narrow side facing the inlet.
[0029] In addition, the model of the packaging machine in this application is not required. This device is applicable to various packaging machines that require alignment. The packaging principle of the packaging machine is a conventional technology and will not be described in detail here.
[0030] Furthermore, a third electric push rod 11 is fixedly connected to the outer side of the closed end of the alignment seat 10, and a push plate 13 is fixedly connected to the telescopic end of the third electric push rod 11. The closed end of the alignment seat 10 has a through groove, and the telescopic end of the push plate 13 is slidably installed inside the through groove. The length of the push plate 13 is less than the width of the object.
[0031] Furthermore, a fourth electric push rod 15 is fixedly connected to both sides of the inner surface of the frame 1, and a guide plate 14 is fixedly connected to the telescopic end of the fourth electric push rod 15. The guide plate 14 is set between the aligning seat 10 and the packaging machine inlet.
[0032] Furthermore, distance sensors are provided on the surface of the aligning plate 12, the side of the push plate 13 facing the opening of the aligning seat 10, and the surface of the guide plate 14.
[0033] Initially, the opening of the alignment seat 10 faces the book conveying direction. An inclined plate 9 is used to guide the book into the alignment seat 10. There are two scenarios for the book entering the alignment seat 10: the book enters with its narrow side and the book enters with its wide side. Regardless of whether the book enters with its narrow or wide side, the second electric push rod 8 drives the alignment plate 12 to move the book and align it. When the distance sensor on the alignment plate 12 detects that the distance between the two sets of alignment plates 12 matches the narrow side of the book, the first electric push rod 7 drives the alignment seat 10 upwards, and the aligned book is then conveyed to the two sets of guide plates 14. The book is conveyed to the packaging machine entrance with its narrow edge facing the center. When the distance sensor on the aligning plate 12 detects that the distance between the two aligning plates 12 is adapted to the width of the book, the aligning motor 6 drives the aligning seat 10 to rotate 90 degrees, so that the narrow edge of the book faces the packaging machine entrance. The third electric push rod 11 drives the push plate 13 to move, pushing the book to move so that the book is located in the center of the conveyor belt 2, ensuring that the book can smoothly enter between the two guide plates 14. Then, the first electric push rod 7 drives the aligning seat 10 to move upward, and the aligned book can be conveyed between the two guide plates 14, with its narrow edge facing the packaging machine entrance.
[0034] The ranging sensors used in this device are mainly photoelectric ranging sensors or laser ranging sensors. The appropriate type is selected according to the actual application scenario and accuracy requirements. The structure and detection principle of the ranging sensor are all existing conventional technologies, which will not be described in detail here. Among them, the distance sensor set on the straightening plate 12 is used to detect the distance between the two sets of straightening plates 12. The preset value of the sensor is the narrow side data of the book. When the sensor detects that the distance between the two sets of straightening plates 12 is greater than the preset value after the book is straightened, the system judges that the book orientation is wrong and triggers the adjustment mechanism. The distance sensor set on the guide plate 14 is used to detect the distance between the two sets of guide plates 14, so that the distance between the two sets of guide plates 14 is adapted to the narrow side of the book. The distance sensor set on the push plate 13 is used to detect the distance between the sensor and the frame 1. The preset value of the distance sensor is the sum of half the width of the conveyor belt 2 and half the width of the narrow side of the book. When the distance sensor detects a value equal to the preset value, the third electric push rod 11 stops driving the push plate 13 to continue moving. The book is located in the center of the conveyor belt 2 and aligned with the guide plate 14, and the book can enter between the two sets of guide plates 14.
[0035] It should be noted that the control between each set of distance sensors and each set of electric linear actuators is implemented by a central controller, which is typically a programmable logic controller (PLC) or a microcontroller control system. The controller is responsible for receiving signals from the distance sensors, processing the data, and controlling the movement of the electric linear actuators. The distance sensors transmit the detected distance data to the controller in the form of digital or analog signals. Based on preset logic, the controller sends control signals to each electric linear actuator, such as start, stop, extension, or retraction. The electric linear actuators are typically driven by DC motors or stepper motors. The controller controls the rotation direction and speed of the motors through a drive module, thereby achieving precise control of the electric linear actuators.
