    ５．ADJUSTMENTS AND CHECKS BEFORE USE ５－１．Checking the model number of the main body Identification stamp Check if the machine has the parts which match the nominal diameter of the screws to be loaded. Check the model number of the rail, escaper, robot es- caper guide, and passing plate by referring to the following table.
  • Page 9 ５－２．Basic operations ○Loading the screws ・Turn the power switch ON and OFF so that the brush stops vertically above the rail. ・Open the top cover and load screws on the left and right side of the rail evenly. ・Do not load screws above the surface of the rail. ・Be sure to determine the screw load by observing the machine while it is in operation.
  • Page 10 ○Pick uping Screws ○Action of the escaper ・Pick up the screws at the stopper with the screwdriver on the robot. Use the bit guide to put the screwdriver down vertically into the screwhead's LED screw indicator slots. ねじ取出し部 Escaper ・When the screwdriver is inserted into the screwhead slots, be careful that no contact is made with the escaper or that the screw is not struck forcefully.

Load the screws into the scooping hopper, turn ON and OFF the power switch so that screws are alligned into the rail groove.
  • Page 12 ５－ 4．Checking and adjusting the rail vibration The amplitude and frequency of the rail vibration can be adjusted. The vibration has been adjusted at the factory for screws that correspond with the rail. Put some screws into the rail and turn the power on. If they are delivered smoothly, there is no need for adjustment.
  • Page 13 ５－５．Check and adjust the front and rear sides of the rail Rail fixing bolt Turn OFF the power switch before starting replacement and adjustment. ・If the rail comes into contact with the escaper, or the clearance between the rail and escaper is too large, loosen the rail fixing bolt, hold the rail groove and adjust the rail assembly either backward or forward.
  • Page 14 ５－７．Check and adjust the passing plate Turn OFF the power switch before starting replacement and adjustment. ・Check that the passing plate is adjusted to a height that permits loaded screws to pass just within the limit. Passing plate ・If the passing plate is too low, screws cannot pass. If the passing plate attaching bolt is too high, it will hamper a smooth transport of the screws.
  • Page 15 ５－９．Check and adjust the timer The screw transport feed differs depending on screw type. This machine can make screw unloading smooth through timer adjustment. For screws with a low transport speed, set the timer long. For screws with a high transport speed, set the timer short.

  • Page 16: Maintenance

    ６．MAINTENANCE A dirty rail groove may interfere with the screw transport speed. Clean the dirty rail with a soft, clean cloth dipped in alcohol. If cleaning is difficult, remove the rail from the machine and clean the rail groove. Refer to the next section under『7-1 Replacing the rail assembly』 for replacing. Before removing the rail from the machine, be sure to turn off the power supply and take the screws out of the hopper.

  • Page 19 ③ Check the position of the parts for smooth delivery of the screws. Check that the clearances between the outside edges of the rail and the robot escaper guide-right and left are almost even. If they are in contact, the screws cannot be delivered. If there is too much clearance, on either side, screws may fall into the machine.
  • Page 20 ④ Adjust the escaper notch position.　 Turn the power switch ON while covering the sensor light axis with a small piece of paper. When the power is ON, the screw sensor LED lights up and the escaper rotates around, to the starting point.(Reference point run.) When the escaper stops, loosen the fixing screws and adjust the escaper by hand so that an escaper notch and the rail groove align.
