Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology. Background Technology

[0002] The operation of automated equipment involves transporting various types of goods, and the need for manual intervention during the conveying process to add auxiliary clamping frames can severely impact the efficiency of automated operation and personal safety, significantly reducing equipment uptime. Currently, there are also automated correction devices, such as the published document with authorization announcement number CN 213084601U, authorization announcement date 2021-04-30, entitled "Automatic Correction Device for Cargo Posture and Logistics Conveyor Belt." The disclosed automatic correction device includes a base unit and a first rocker arm unit and a second rocker arm unit mounted on it. Relative to the conveying direction of the conveyor belt, the first rocker arm unit is located in front of the second rocker arm unit, and the first rocker arm of the first rocker arm unit rotates above the conveyor belt. The second rocker arms of the second rocker arm unit are symmetrically arranged on both sides of the conveyor belt and rotate synchronously in the opposite direction above the conveyor belt. Thus, the rotation of the first rocker arm acts as a barrier to the cargo; the end of the second rocker arm simultaneously squeezes the side of the cargo to correct its posture. In other words, this automatic correction device can automatically correct the position and posture of the cargo relative to the conveyor belt.

[0003] However, there is a problem with current similar correction devices. If the products are clamped on both sides of the conveyor belt and the clamping mechanisms on both sides are not synchronized, and the friction between the clamping mechanism and the product is too large, the products may be deviated. Therefore, it is necessary to design a device that can clamp and correct reliably and will not cause secondary product deviation due to errors. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to realize a device that can ensure reliable movement of railings or boxes during automated conveying.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mechanical device for automated conveying, clamping, correction and fixing, the device is symmetrically arranged on both sides of the conveyor belt, the device includes a laterally extending cylinder, a frame is fixed to the end of the cylinder rod of the cylinder, a sliding plate is fixed to the outer end of the frame through a horizontally arranged slide rail, and a return device is provided between the frame and the sliding plate.

[0006] The return device includes an iron sheet fixed on a slide plate, and a telescopic rod extending along the conveyor belt conveying direction is fixed on the frame. An electromagnet for attracting the iron sheet is fixed to the end of the telescopic rod.

[0007] The telescopic rod is an electric cylinder, and the telescopic length of the telescopic rod is slightly greater than the travel length of the sliding plate relative to the slide rail.

[0008] When both the electromagnet and the sliding plate on the telescopic rod are at the end, the electromagnet is positioned in front of the magnet.

[0009] Sensors located on the side of the conveyor belt are provided at both the front and rear of the device. These sensors are connected to and output sensing signals to the PLC.

[0010] The PLC is connected to and outputs drive signals to the cylinder and the return device.

[0011] The devices located on both sides of the conveyor belt are identical and are both driven and controlled by the same PLC. The opposing surfaces of the sliding plates are made of a smooth material.

[0012] This invention enables smooth and automatic switching between large and small boxes with clamping effect without human intervention, solving the problems of jamming and equipment misalignment during the conveying process. It increases clamping accuracy, reduces manual operation time, ensures personal safety, and significantly improves production efficiency. Attached Figure Description

[0014] The following description, with reference to the accompanying drawings, details the specific implementation of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the function and working principle of each part, the manufacturing process, and the operation and use methods. This will help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model.

[0015] The automated conveyor clamping, straightening, and fixing mechanical device consists of two clamping devices symmetrically arranged on both sides of the conveyor belt. The clamping devices on both sides of the conveyor belt have identical structures, and their fixed positions are slightly higher than the surface of the conveyor belt. The device includes a laterally extending cylinder 3, which extends and retracts horizontally, perpendicular to the conveyor belt's transmission direction. A frame 1 is fixed to the end of the cylinder 3 rod. The cylinder 3 clamps by pushing the frame 1, which increases the clamping distance by up to three times. The open-type transfer method ensures that large and small objects smoothly enter the clamping position, and no manual intervention is needed to add an auxiliary clamping frame when moving to the clamping position. No human intervention is required during the clamping process, and the device also has a straightening function.

[0016] To prevent secondary product displacement caused by the clamping mechanism remaining stationary relative to the product on the conveyor belt, a sliding plate 5 is fixed to the outer end of frame 1 via a horizontally mounted slide rail. The slide rail's movement direction is horizontal to the conveyor belt. The sliding plate 5 is a vertically mounted flat plate with a smooth facing surface. The lower edge of the sliding plate 5 is slightly higher than the surface of the conveyor belt. The slide rail allows the sliding plate 5 to move a certain distance with the product after each clamping, ensuring that the displacement of the sliding plate 5 relative to the product does not affect the product, especially preventing secondary displacement. The sliding plate 5 is always at the beginning, determined by the conveyor belt's transmission direction. Because the sliding plate 5 moves from the beginning to the end after each displacement, a return device is needed to return the sliding plate 5 to the beginning, preparing for the next product correction. Therefore, a return device is provided between frame 1 and the sliding plate 5. Thus, when the sliding plate 5 moves with the product, the clamping time needs to be controlled so that the displacement distance (clamping time) of the sliding plate 5 is less than the travel of the slide rail.

[0017] The return device includes an iron plate 6 fixed on a sliding plate, and a telescopic rod 8 extending along the conveyor belt direction fixed on a frame 1. The telescopic rod 8 can be an electric cylinder. An electromagnet 7 for attracting the iron plate 6 is fixed to the end of the telescopic rod 8. The fixed height of the electromagnet 7 is the same as that of the iron plate 6. It is necessary to ensure that the frame 1 does not affect the displacement of the electromagnet 7. When the electromagnet 7 is extended to the end by the electric cylinder, if the sliding plate 5 is also located at the end, that is, when both the electromagnet 7 on the telescopic rod 8 and the sliding plate 5 are at the end, the position of the electromagnet 7 is in front of the magnet. At this time, the position of the electromagnet 7 is directly facing the iron plate 6 with a very small gap. Thus, when the electromagnet 7... When energized, the electromagnet 7 can attract the iron plate 6. The extension length of the telescopic rod 8 is slightly greater than the travel length of the sliding plate 5 relative to the slide rail. When the electromagnet 7 retracts along with the telescopic rod 8, it will attract the iron plate 6, causing the sliding plate 5 to return to the starting point as well. However, because the extension length of the telescopic rod 8 is slightly greater than the travel length of the sliding plate 5 relative to the slide rail, the sliding plate 5 will move to the starting point of the travel first, while the electromagnet 7 will continue to retract and detach from the iron plate 6. This design ensures that the sliding plate 5 returns to the starting point reliably and avoids the electromagnet 7 still having a small amount of magnetism when the power is off, which could affect the iron plate 6. This ensures the smoothness of the sliding plate 5 sliding on the slide rail.

[0018] The core of the entire device is the PLC4. Sensors are located on the sides of the conveyor belt at both the front and rear of the device. These sensors can be laser sensors to detect the position of the product. At the same time, the PLC4 is connected to and outputs drive signals to cylinder 3 and the return device. In this way, by connecting the sensors and outputting sensing signals to the PLC4, the PLC4 knows the clamping timing of the device. The devices on both sides of the conveyor belt are the same and are driven and controlled by the same PLC4, ensuring the relative synchronicity of the operation of the two devices.

[0019] This utility model device can smoothly and automatically switch the clamping effect of large and small boxes without human intervention, solve the problems of jamming and misalignment in the conveying process, and the clamping device will not cause the product to shift again due to friction when retracting, which increases the accuracy of the clamping position, reduces the time of manual operation, ensures personal safety, and greatly improves production efficiency, which is more in line with the logic of automation.

[0020] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
