Detailed information

  • APG-7TB.jpg

    Product Name: Poka-Yoke Shutter Model: APG-7TB Compared to the conventional model "APG-7B," the driving force has increased by about twice, allowing it to accommodate larger doors. (This eliminates the need for lightweight processing of doors that was previously done.) It supports not only picking (retrieval) operations but also the equipment and systems on the input side. For inquiries regarding equipment and systems, please contact us separately. ● Compatible with both NPN and PNP (see connection diagram) ● Rich settings for the opening and closing angles of the shutter (7 levels for outward opening, 2 levels for inward opening) ● Can be mounted on φ28 round pipes and aluminum pipes (outer diameter 28mm) ● The pipe mounting holder and arm section are made of metal for excellent durability ● The housing is made of glass-filled polycarbonate, considering oil resistance ● Lamp colors and various operations can be set (LED lamps support 6 colors) ● ON/OFF settings for forced opening error output are possible ● Equipped with an answer-back mode function* * After operating the lever or push switch, this function keeps the lamp lit with a different lamp operation until the door closes and the ON signal from the upper controller is cut off.

  • APG-RS3_gray.jpg

    Product Name: Poka-Yoke Roll Shutter Model: APG-RS3 This can be used for large openings that traditional poka-yoke shutters could not accommodate. Since the shutter section does not protrude forward, it can be used in narrow picking areas. The screen section can be easily modified by the customer, allowing for size adjustments for smaller openings. It is possible to install the screen section and control section separately. The length of the screen can be set to any desired measurement.

  • ポカよけコントローラ(HP用)[500pix][NEWなし](BCRなし).jpg

    Product Name: Poka-Yoke Controller Model: APG-CR1 This is a controller that manages the instructions for retrieving and inserting parts and products. It allows for the easy construction of a Poka-Yoke system using barcodes or QR codes. It supports not only the picking (retrieval) operations of existing work shelves but also insertion management and sorting management. For details on installation methods and systems, please contact us separately. ● NPN-compatible controller ● Registration possible with either barcodes or QR codes ● Can connect up to 60 Poka-Yoke products (60 input points, 60 output points) ● Standard equipped with a check mode that allows for one-touch trial operation ● The touch panel features a 4.3-inch color LCD for clear and easy-to-understand display content ● Equipped with sequential operation and simultaneous operation modes
