Weight Recording Unit
A device for the recording oi scale weights has been developed by Howe Scale Co. for use with its tape-drive dial «•cales. It has been named the Teleprint and is the result of over three years of research and engineering in the weinht printing fields.
The Teleprint combines electronic, electrical, and mechanical engineering to "read" the scale dial and convert it to weight-printings set-up on type wheels for impression on a variety of tickets and forms and single- and double-roll tapes. Three components make up the Teleprint —a take-ofi unit, mounted as a part of the dial housing; a servo-amplifier, and a re corder unit, remotely connected to the take-off by cable.
Of interest to scale users is the remote feature of the Teleprint. With the takeoff and recorder mechanisms designed as separate units, the recorder may be located 5(H) or more feet away from the scale site with only the addition of extra cable. It is flexible and can be mounted on a desk or portable stand.
For use with Howe cabinet (d rop weight ) dials, an additional feature has been developed. Suitable interlocks are used to prevent printing until correct number of weights are in the system, and a control panel allows operator to control weight-printing entirely from remote location by indicating when weights are to be added or removed. With the cabinet drop weight models, the Teleprint automatically adds and integrates the unit weight additions to print total weights.
The unit can be adapted to automatic weighing applications. Recorder print button circuit may be extended to conveyor line or lever system so that the passing of boxes or loading of hoppers and tanks can register desire to print, and weight will then be automatically recorded when scale comes to balance.
