Thus, it is most suitable for large-scale packaging runs using similar size cases.

You can find it in different sizes, and speeds hence guarantees a specific system that fits your particular packaging needs.

On the other hand, random case sealer has adjustable tape heads, making it suitable for packaging cases of different heights.

Essentially, it features a sensory device that allows tape head to raise or lower until it gets the ideal height.

As such, it offers great packaging solutions when packing different box sizes simultaneously.

Nonetheless, you can find uniform case sealers and random case sealing machines in both automatic and semi-automatic running formats.

Thus, you will hardly need to adjust the equipment for different runs since it has sensors enabling it to re-adjust accordingly based on height of the case.

Parts Of Random Case Sealing Machine

A typical random case sealer features a wide range of integrated parts to deliver a fully functional unit.

However, the notable parts you should be familiar with in this machine include the following;

Belts – For transporting cases within the equipment and through the changes in direction or elevation.

Tape head – It is a transducer device that converts electrical signals into magnetic oscillations, thus help in adjusting to case height accordingly.

Metal rollers – Designed to assist in efficient movement of cases from one station to another within the equipment during sealing process.

Electric panel – It is a box holding different types of electrical components used in running the machine.

Control switches – They are used for closing and opening different control circuits in automatic and semi-automatic control systems.

Adjustable top guides – Are used for keeping the flaps squared during case sealing process.

PLC touchscreen – It displays various operating parameters of the machine during sealing for easy control and monitoring.

Tape roller – Applies the sealing tape on the case surface for secure packaging.

Photoelectric detector – This device has an inbuilt light-emitting component, which activates a light beam and detects presence or absence of cases during sealing.

Safety guard – Protects or reduces imminent injuries or damage to the operator or machine respectively.

How Random Case Sealing Machine Works

The working principle of this machine is quite straightforward and starts with feeding random size cases with opened flaps into the equipment.

Automated arms in the machine detect the presence of the case and get the right height.

The system is activated to fold down the top flaps of the package.

Once the flaps are folded, the case moves through the tape head to allow for sealing of the flaps.

Immediately the flaps are closed, flaps are sealed, the case packages are ejected from the machine’s back end for subsequent handling operations.

The process repeats for all the cases at relatively high speeds.

Features Of Random Case Sealing Machine

Essentially, the most outstanding feature of this case sealer is its ability to seal different case sizes randomly and accurately without adjusting any settings.

However, it also exhibits a number of excellent features making it among the best considerations in the market, which include the following;
