【正文】 hod In order to help operators select the right parts for the right step in a process the “sequencing” aspect of the motionstep method is used. This is especially helpful when using multiple parts that are similar in size and shape. In this example, each step of the machine cycle is wired to an indicator board and a timer. If each cycle of the machine is not performed within the required “time” and “sequence”, the indicator light for that step will be turned on and the machine will stop. Indicator Board Machine 62 ? 2023, , LLC, all rights reserved Types of Sensing Devices Sensing devices that are traditionally used in pokayoke systems can be divided into three categories: 1. Physical contact devices 2. Energy sensing devices 3. Warning Sensors Each category of sensors includes a broad range of devices that can be used depending on the process. 63 ? 2023, , LLC, all rights reserved Physical Contact Sensors These devices work by physically touching something. This can be a machine part or an actual piece being manufactured. In most cases these devices send an electronic signal when they are touched. Depending on the process, this signal can shut down the operation or give an operator a warning signal. 64 ? 2023, , LLC, all rights reserved Touch Switch Used to physically detect the presence or absence of an object or itemprevents missing parts. Used to physically detect the height of a part or dimension. 65 ? 2023, , LLC, all rights reserved Energy Sensors These devices work by using energy to detect whether or not an defect has occurred. Fiber optic Photoelectric Vibration 66 ? 2023, , LLC, all rights reserved Warning Sensors Warning sensors signal the operator that there is a problem. These sensors use colors, alarms, lights to get the workers attention ! These sensors may be used in conjunction with a contact or energy sensor to get the operators attention.
