Definitions

  • the present disclosure relates to a wrapping apparatus for wrapping a load with packaging material, and more particularly, to a wrapping apparatus having a top loading and threading packaging material dispenser.
  • Various packaging techniques have been used to build a load of unit products and subsequently wrap them for transportation, storage, containment and stabilization, protection, and waterproofing.
  • Products may be stacked as a load on a pallet to simplify handling of the products.
  • the load is commonly wrapped with packaging material.
  • One system uses a stretch wrapping machin to stretch, dispense, and wrap stretch packaging material around a load.
  • Stretch wrapping can be performed as an inline, automated packaging technique that dispenses and wraps packaging material in a stretch condition around a load to cover and contain the load.
  • Stretch wrapping whether accomplished by a turntable, rotating arm, or vertical rotating ring, typically covers the four vertical sides of the load with a stretchable packaging material, such as polyethylene packaging material. In each of these arrangements, relative rotation is provided between the load and the packaging material dispenser to wrap packaging material about the sides of the load.
  • Conventional stretch wrapping apparatuses employ a packaging material dispenser having two closely spaced rollers to stretch between them a web of thermoplastic stretch packaging material. Such a stretch wrapping apparatus performs admirably in accomplishing its intended goal of wrapping a load with a stretched web of packaging material.
  • the procedure of loading and threading the packaging material through the series of rollers in the packaging material dispenser prior to operation of the stretch wrapping apparatus has been found to be time consuming and difficult.
  • a stretch wrapping apparatus with pre-stretch rollers have the following features.
  • the upstream and downstream pre-stretch rollers should be closely spaced during operation to prevent neckdown of the packaging material as it is being substantially stretched in the dispensing direction. Since the forces exerted on a web of packaging material between the pre-stretch rollers is very significant, for example in the order of 50 pounds of force, the frame and the mounting of the pre-stretch rollers should be required to be very sturdy.
  • the surface of the pre-stretch rollers should be covered by the packaging material over a sufficient extent such that the packaging material does not slip on the pre- stretch rollers.
  • the rotational inertia of the pre-stretch rollers should not be so high as to require excessively high power to vary their velocity.
  • a series of idle rollers are used to support the packaging material proximate to the pre-stretch rollers.
  • the packaging material follows a tortuous path around the closely-spaced pre-stretch and idle rollers.
  • the downstream pre-stretch roller has a faster surface speed than the upstream pre- stretch roller. This stretches the packaging material between the upstream and downstream pre-stretch rollers in the dispensing direction.
  • the present disclosure is directed to overcoming one or more of the problems set forth above, as well as other problems associated with loading and threading a packaging material dispensers.
  • a packaging material dispenser including one or more packaging material dispensing rollers for dispensing packaging material
  • an apparatus for wrapping a load including a packaging material dispenser having one or more dispensing rollers for dispensing packaging material also are provided.

  • the packaging material dispenser may also include a packaging material dispensing assembly mounted on an upper surface of the base plate and defining at least a portion of a packaging material path. A first portion of the packaging material path may extend behind the packaging material dispensing assembly.
  • the upper portion of the roll carriage may include an opening defining a packaging material path access area positioned to provide access to a top of the packaging material path.
  • the packaging material dispenser may also include a packaging material dispensing assembly drive mechanism extending below the base plate.
  • a packaging material dispenser may include a roll carriage having an upper portion and a lower portion, and a base plate separating the upper portion from the lower portion.
  • the packaging material dispenser may also include a packaging material dispensing assembly mounted on an upper surface of the base plate and defining at least a portion of a packaging material path.

At least one of the upstream portion and the downstream portion may be accessible via one or more passageways at the top of the roll carriage.
  • the packaging material dispenser may also include a drive assembly for the packaging material dispensing assembly, the drive assembly extending below the base plate.
  • a packaging material dispenser may include a roll carriage having a base plate on which a packaging material dispensing assembly is mounted.
  • the packaging material dispenser may also include a packaging material path for packaging material being dispensed by the packaging material dispensing assembly.
  • the packaging material path may include a substantially U-shaped configuration including a first leg through which packaging material is drawn in a first direction.
  • the packaging material path may also include a second leg through which packaging material is drawn in a second direction different than the first direction, and a connecting portion connecting the first leg to the second leg. At least one of the first leg and the second leg may be accessible via one or more passageways at a top of the roll carriage.

  • Apparatus 100 may also include a column 156, on which packaging material dispenser 102 is mounted for vertical travel along column 156. While packaging material 104 is being dispensed by packaging material dispenser 102, relative rotation between packaging material dispenser 102 and load 101 , which may be provided by rotatable turntable 188, may wrap packaging material 104 around load 101.

  • Packaging material dispenser 102 may travel vertically along column 156 from a bottom portion of load 101 to a top portion of load 101 , and then back down to the bottom portion, while the relative rotation is being provided, to spirally wrap packaging material 104 about load 101.
  • the method for loading packaging material in packaging material dispensers 202 and 302 may be similar to the method described above with respect to packaging material dispenser 102. There are, however, differences between the methods.
  • Packaging material dispenser 302 may travel vertically along column 356 from a bottom portion of the load to a top portion of the load, and then back down to the bottom portion, while the relative rotation is being provided, to spirally wrap packaging material 304 about the load.

Abstract

L'invention porte sur un distributeur de matériau d'emballage, qui peut comprendre un support à rouleaux ayant une partie supérieure et une partie inférieure, et une plaque de base séparant la partie supérieure de la partie inférieure. Le distributeur de matériau d'emballage peut également comprendre un ensemble de distribution de matériau d'emballage monté sur une surface supérieure de la plaque de base et définissant au moins une partie d'un trajet de matériau d'emballage. Une première partie du trajet de matériau d'emballage peut s'étendre derrière l'ensemble de distribution de matériau d'emballage. La partie supérieure du support à rouleaux peut comprendre une ouverture définissant une zone d'accès de trajet de matériau d'emballage positionnée de façon à permettre l'accès à un sommet du trajet de matériau d'emballage. Le distributeur de matériau d'emballage peut également comprendre un mécanisme d'entraînement d'ensemble de distribution de matériau d'emballage s'étendant en dessous de la plaque de base.
