1400rf Fully Automatic Case Sealer

Functional Description

The 1400rf case sealer utilizes a unique system of two floating counterbalanced heads to automatically seal random sized cases. Cases are indexed into the sealer as they are detected by the infeed photo-eye.Accelerator belts pull the case into the sealer creating a gap between consecutive cases. The indexing gate stops the next case as theheavy-dutychain-drivenflight lugs transport the first case into the centering arms. The leading minor flap is closed by an integral drive belt system that lifts the flap folder section up to the top of the case. Aphoto-eyesenses the leading edge of the case, actuating the flap folding section counterbalance brake and signaling the trailing minor flap kicker to close the flap. The major flaps are folded as the case continues to move forward. As the first case leaves the flap folder section, the indexing gate allows another case to enter while the first case pushes the counterbalanced taping head section up. A second counterbalance brake insures proper down force on the top of the case for applying a secure tape seal.

Flap Folder Assembly

Features an integral drive belt system that powers the flap folder section up to the top of the case, then a counterbalance brake secures the head against the case as the major flaps are folded.

Taping Head Assembly

Incorporates a 3M Accuglide™ II tape head, counterbalance brake, and compression rollers for tight, positive case sealing.
