CHAPTER 1: INTRODUCTION
The Burford
®
2200M/2300M 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.
New Holder / Shear actuator practically eliminates adjustment while
greatly reducing wear
Sealed Encoders
Longer belt life
Lower energy consumption
Modular design allows critical components to be changed out in one
simple step
New, quieter brush design

Conveyor Requirements
Depending on conveyor speed and flight spacing, the Smart Tyer is capable of operating
speeds of up to 100 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, flight spacing up to 18” 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.
Minimum size for a service transformer shall be
1.8
KVA.
Introduction 15
Bag Neck Length Requirements
1. Measure the diagonal across the end of the product.
2. Take one-half of the diagonal measurement and add 3 inches (76mm) 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 taping operation. Please consult a reliable
package manufacturer for your specific needs or contact Burford®Corp. if we can be of
assistance.
Short bag neck lengths may cause excessive
package jams.

CHAPTER 2: KEY COMPONENTS
Below is a list of key components that you must familiarize yourself with to gain a better
understanding of how the Smart Tyer functions.
Tyer Head
The Tyer Head is made
up of all the mechanical
and electrical
components
necessary to perform a closure. The Tyer Head applies the ribbon to the product.
When the bag trips the trigger arm, the 4 servo motors work together to apply
ribbon with either 4 or 5 twists to the bag. It is housed on a detachable stand.
