    Sensing in Food Packaging and Conveyor Image

    包装肉类的输送系统检测存在一些独特的挑战。在这类应用中,肉类已准备好并放在深色塑料托盘上。在对托盘进行包装和标记之前,托盘会沿一系列白色传送带移动。在这个多输送带配置中,传感器必须放在每条传送带上,以检测依次进入的食品托盘。

    挑战

    食品在准备发货和陈列到柜台之前会经过不同的包装阶段。自动化设备和传感器必须能够保持准确和稳定,同时承受恶劣的冲洗环境。

    Food products move through various stages of packaging as they are prepared for delivery and display. Automation equipment and sensors must perform accurately and consistently while withstanding harsh washdown environments.

    Inspection on a packaged meat conveying system presents some unique challenges. In this application, meat is prepared and placed on a dark plastic tray. Before the trays are wrapped and labeled, they move along a series of white conveyor belts. In this multiple-conveyor belt configuration, sensors must be positioned over each belt to detect the food trays as they move through the process.

    说明

    这项应用的检测特点虽然简单,但也很独特:传感器直接放置在白色、高反射背景上,并且必须检测较暗、低对比度、不同纹理的物体。EZ-BEAM T18固定区域传感器是一种理想的解决方案。它有清晰的检测分界点,对颜色变化不敏感 – 它会在一定范围内检测物体的存在,同时忽略背景。传感器的直角外壳可通过让线组连接与安装组件保持平行来实现小巧的机器设计。当传感器处于传送带上方的高度可在检测食品托盘时忽略背景,则无需调整检测范围。

    QD型T18传感器达到了IP69K防护等级,和EZ-BEAM系列中的许多传感器一样,它们的设计也可承受频繁、恶劣的冲洗环境。
