Case Loaders & Packers

Lantech Case Loading Technology

The Lantech case loading technology is a module which complements the modular Lantech case erecting and case closing technology. By integrating a case erector, a collating unit to suit the client's specification with the appropriate loading technology, and a case closing unit we achieve a tailor-made Lantech Case Packer.

Depending on the loading technology, this results in a Top Loader or a Side-Loader with the emphasis on controlled and careful handling of product and case.

Lantech engineers use parts from their standards library, employ many standardised build units, and whenever possible, standardised modules. This offers you, the client, the advantage of specifying your own tailor-made machine, working in close consultation with our qualified engineers. And through this flexible standardisation out build cost is kept to a minimum.

Lantech Case Packer (Top Loader) RCP-2

Erecting and transporting a case into the loading position occurs in the same way as in the Side Loader. When the case is in position, the centering frame is activated. The collated product is moved onto two horizontal sliding plates (bomb doors) situated above the case. The Pick & Place head then picks up the collated product, lifts it clear of the bomb doors, which then open and the Pick & Place head moves the product down into the erected case.

As an alternative to the bomb doors Lantech use - where appropriate - a high-speed retractor belt. Once filled, the case is closed with self-adhesive tape or hot melt glue after which it leaves the machine.

Products for Top Loading:

Certain products - such as pies, jerry-cans, jars and bottles - need to be top loaded because the product must remain in upright position during loading and transportation.

Product pick-up Heads, Gripper or Vacuum:

A Pick & Place head is made to suit each product. Whenever possible Rembrandt engineers choose from the range of modular, standard solutions. Some products can be picked up in single or multi-layers by a vacuum or gripper Pick & Place head. Other products may need to be picked up by a special, mechanically operated head.

Each product is analysed separately.

Centering Frame:

Products often need to be packed tightly into the case. To avoid damage to both product and case during loading, Rembrandt utilise a centering frame with shoehorn like fingers which fold the top flaps outward to allow smooth and unhindered loading.

When loading cylindrical products, the centering fingers hold the flaps in the middle. When loading rectangular products, the centering fingers sit in the corners of the case and operate just like a shoehorn. Both types of centering frame are standard change parts for each case size. For a large variety of case sizes we recommend the adjustable centering frame.

Pusher for RCP-2/3:

The pusher on the top loader is used to collate the products and move them under the Pick & Place head. On the side loader, the pusher is used to collate the products in stages and move them - when handling multi-layers - onto a parking section from where the complete collation of product is moved into the case. A pneumatic pusher is used for lower speeds and a mechanical pusher is used for higher speeds. There is a choice of various standard versions, possibly complemented with options.

The erected case is transported to the loading position by two ‘high grip’ side belts where it is turned through 90 degrees after which the complete collation of product is moved into the case in one operation. The filled case is then turned into the upright position, followed by the sealing of the bottom and top flaps with tape or hotmelt glue in the closing section.

Products for Side Loading:

Rigid products often need to be placed in the case on their narrow side so that they can cope with higher loads during transport. Side loading is then ideal.

Depending on product dimensions and the required collation pattern, an appropriate set of change parts is required. We are often able to use standard parts, but sometimes tailor-made solutions are required.

Alternatively, a Pick & Place system with a combination of horizontal and vertical movements is used when dealing with unstable products.

Lantech Case Packer CP-300

A.M.J Maters - Lantech Case Packer CP-300

The CP-300 is based on the proven Lantech case erecting (C-300) and loading techniques. This very compact case packer erects a case and feeds it to the loading position, where the centering frame is activated. The pick & place unit picks up the product from the integrated infeed belt conveyor and places it in the erected case. Afterwards the filled case is discharged.

The Case Erecting Unit

The case erecting unit is based on the acclaimed C-300/BOXER case erector. The case blanks are placed simply and easily into the "ergonomic", low level, walk-in type case blanks magazine.

The unique Lantech hinged frame with vacuum suction cups picks up a case blank from the blanks magazine, holding it firmly on a short and a long panel, and opens it into a perfect, square case. Then the short flaps followed by the long flaps of the case are folded in by the flap-folding assembly with the folding movement towards the stationery case.

The pusher bar then moves the erected case into the tape closing section where the bottom flaps of the case are closed with self-adhesive tape, and the case leaves the machine.

The "Self Teach Mode" Pick-Up System

This pick & place system consists of two servo-motors with a Motion Control unit and a Vacuum Pick-up Head. The pick-up head is manually placed - by means of the jog function - in the required pick-up and release positions which are stored in the memory of the control system.

The Centering Frame

Frequency controlled side belts ensure that the case can be stopped with great accuracy in the loading position. The adjustable centering frame with its four shoehorn type fingers is activated whereby the top flaps are folded out sufficiently to allow smooth loading of the product into the case.

The Lantech centering frame guarantees excellent positioning and guiding of the product into the erected case - the "shoe-horns" also ensure that product does not hit the glue strip/joint inside the cases.

The Product Infeed Conveyor

Our product infeed conveyor has a belt width of 350mm and can be adapted to accept e.g. multiple rows of product which are then fed to the "pick-up" position.
