Pin Installation Technology

Model PR Semi-Automatic Pin Inserter

This robust, vertical pin insertion machine is ideally suited for moderate- to high-volume production applications requiring up to 1.3 kN (300 lbs.) of installation force. For higher insertion forces, the Model CR Heavy Duty Pin Inserter is available in multiple sizes to accommodate specific application requirements. The pin insertion head advances and retracts for ease of loading and unloading of the components to be pinned. The machine’s insertion bushing is positioned close to the part for smooth installation.

A vibratory feeder and orientation head transfers the pin from the feeder bowl to the installation position, eliminating the need for the operator to handle the pins. A quick-clear mechanism allows for easy clearing of the feed tube without the need for tools when changing pin size or performing maintenance.

Optional enhancements include: pin presence sensing, force monitoring, vision system, full perimeter guarding, ergo-lift table, and more!

Application Success Stories

Plastic Spray Bottle Nozzle

Installing a Tamperproof Retaining Pin in Molded Plastic Spray Bottle Nozzle

Customer Challenge:

A manufacturer of molded plastic spray bottle nozzles used in restaurants requested SPIROL’s help to “tamperproof” their adjustable spray tip so that the spray volume could not be adjusted resulting in too much or little solution applied.

SPIROL SOLUTION:

  • SPIROL’s Engineers determined that the hole through the nozzle assembly could be created by using a pin to pierce the plastic during installation.
  • The swaged chamfers on SPIROL’s Coiled Pin make an ideal reduced diameter for piercing a plastic hole, while the larger body diameter of the Coiled Pin retains itself securely within the assembly.
  • The nozzle caps arrive to SPIROL’s Model PR Pin Inserter pre-adjusted for the proper piercing location. The operator loads the components into the fixture and activates the machine to install the pin. No machine adjustments are required during installation.
  • The installed Coiled Pin provides rotational resistance and prevents the end user from adjusting the spray volume – making it tamperproof!
