Description

The Nigrelli Systems’  Model SP-2000 Multi-Packer is a continuous motion high speed packaging machine designed to wrap a flat corrugate blank around multiple packaging configurations.  This wrap-around style Multi-Packer is capable of producing in excess of 200 packs per minute, with the capacity of 2400 containers per minute. 

Product is conveyed into the packer infeed via customer supplied side-off conveyor.  Sensors are mounted on the Multi-Packer infeed prior to product lane division. The Multi-Packer regulates the speed of the side-off conveyor to address line pressure. After  product has entered the lane division part of the infeed conveyor system; the populated lanes are separated to allow for a star wheel to regulate the can feed into the flighted product chain conveyor.  

The flighted product chain groups the package configuration. Different pack group sizes are obtained by phasing the front portion of the flighted product conveyor, either via hand crank or motor driven with the auto changeover option.  Cans or product are transferred from the product chain transversely onto the partially formed carton via the servo driven product loading belt.  As the cans are being loaded, the front minor flaps on the carton’s opposite side are plowed shut, and the rear minor flap is tucked with a servo driven rotary tucker.  The tabs are held closed with a fixed guide rail.  Cans continue to load until the carton is fully loaded. 

Simultaneously, corrugated blanks are automatically loaded into the overhead hopper. A load hopper photoeye detects when the auto loader can add more trays to the hopper. The  rotary board placer pulls a tray from the hopper assembly and places it on a side lug transfer conveyor. A vacuum pump supplies vacuum to suction cups on the rotary placer system. Timing of the vacuum supply is accomplished via a mechanical rotary valve. A photoeye inspects for the tray; if the rotary placer misses a pick, the packer will go into low speed and cycle stop, so the operator can place a tray or carton in the appropriate empty pocket. Also mounted on the side lug tray conveyor is a double tray detect system. Sensors will determine if more than one tray has been pulled from the hopper, or if the board pulled has been damaged.

The board erector picks up the board blank with suction cups from the tray side lug transfer via servo driven board folding bar; folding the carton or tray into a “J” shape. The lower flaps on the board are plowed under hold down rails as it transfers into the pocket chain. Timing of the vacuum for the board erector is accomplished via a mechanical rotary valve.  

The pocket chain is the main transfer conveyor; driven and controlled via a servo motor. The pocket chain drive also slave drives the board erector. After the trays or cartons are loaded into the pocket chain, it is ready to start loading product.

As the carton and product continue to move downstream, minor flaps on the loading side are tucked and held.  Next, the top panel is plowed down to a pre-glued position.  The manufacturer’s flap is tucked with a pair of rotary wheels.  A back panel-squaring device is introduced to ensure a square package and accurate application of glue to the flap.  Glue is applied to the flap.  The large top panel is brought from its pre-stage position to fully closed.  At the same time, glue is being applied to the side minor flaps; and the lower and upper major flaps are being folded.  

The product enters the compression section. Top compression occurs first holding the package square. Shortly after, the side of the package is also compressed. Each compression belt has its own drive motor, and is controlled with a servo drive motor. Finished packages are conveyed out of the Multi-Packer via a short accelerator belt.
