1.0 INTRODUCTION
1.1 General Information
The Burford®2200 Series Electronic Smart Tyer is designed to close plastic bags
with twist tie ribbon in a wide variety of automatic packaging applications. The
tyer uses a microprocessor to control and coordinate the motion of four servo
motors, which perform the twist tying function. This machine is normally installed
onto a bagger or conveyor and interfaced into the existing control system to
create a complete package closing system.
1.1.1 Specifications
Depending on conveyor speed and flight spacing, the Smart Tyer is capable of
operating speeds 100 plus packages per minute. The Smart Tyer operates on a
nominal 110 Volts, 60 Hz, single-phase alternating current. 15 amp service is
recommended. Smart Tyer connections for bagger interlock and safety circuits are
provided standard. A counter signal is provided which can be used in conjunction
with an external counter (not provided).
On flighted conveyors, any flight spacing may be used, but the tyer can have a
higher production rate (packages per minute) with a small flight spacing, such as
nine inches. This tyer can also be used on belted conveyors that provide consistent
spacing. All referenced measurements are in inches except as noted.
1.1.2 Bag thickness requirements
For optimal performance, a minimum bag thickness of 1.25 mil is recommended.
Note: Minimum size for a service transformer shall be 1.5KVA.

1.1.3 Bag neck length requirements
1. Measure the diagonal across the end of the product.
2. Take one-half of this diagonal measurement and (depending upon the
machine combination) add three or four inches to determine the required
length of the bag neck.
This formula is provided in case you are developing a new product package and
need to calculate a bag neck length for an automatic tying operation. Please consult
a reliable package manufacturer for your specific needs or contact Burford®Corp. if
we can be of assistance.
CAUTION: Short bag neck lengths can cause excessive ribbon drops and
package jams.
