Description
PAPER CONVERSION DISPENSER MACHINE
FIELD OF THE INVENTION
The invention relates generally to a paper conversion machine, more particularly to a dunnage dispensing machine that reduces a flexible stock sheet-like roll material of a supplied width into a narrower crumpled paper;
and dispenses the latter directly into a shipping case or box containing fragile goods for protection in the form of dunnage and/or void fill product.
BACKGROUND OF THE INVENTION
Protective packaging material is used in every shipping process to fill voids and protect products by cushioning.
Commonly used protective packaging material consists of plastic bubble rolls, liquid foam injection molding and polystyrene loose fill. These plastic packaging materials are not biodegradable and it has become increasingly important in light of many industries adopting more progressive policies in terms of environmental responsibility.
The forgoing and other disadvantages of conventional plastic packaging materials have made paper protective packaging material a very popular alternative. One form of paper dunnage, which is very well known in the art, is provided in a relatively low density cushioning material obtained from flexible sheet-like paper using a cushioning conversion machine.
U.S. Patents No. 5,607,383 and No. 5,593,376 to Armington et al, are representative of a large group of Patents disclosing a modular cushioning conversion machine. The disclose cushioning conversion machines for producing a dunnage product from supplied sheet-like stock material, for example, in roll form; and more particularly, to an improved modular construction of such machine.
U.S. Patent No. 5,131,903 to Levine et al., discloses an apparatus for crumpling and dispensing dunnage from a roll of flexible, stock paper material, and more particularly, to a disposable, dunnage dispensing apparatus which structurally reinforces its outer housing and that maintains a length of dunnage dispensed therefrom in a crumpled state. .
In machines of the above-described type there is considerable friction between the moving dunnage product and the different parts of the machine. The friction becomes more severe in places where the width of the strip is significantly reduced, thus causing increased relative tension acting on the strip and, as a result, wears the strip off. Consequently, the effective machine productivity and reliability are well affected.
OBJECTS OF THE INVENTION
An object of the present invention is to provide a paper conversion dispenser machine that obviates the above-mentioned disadvantages.
Another object of the present invention is to provide a paper conversion dispenser machine that is extremely reliable to use.
A further object of the present invention is to provide a paper conversion dispenser machine that is relatively simple to produce.
Yet another object of the present invention is to provide a paper conversion dispenser machine that is essentially friction free at the paper shaping member, especially at the pre-entry section where the paper is first significantly reduced in width.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to the annexed drawing the preferred embodiment of the present invention will be herein described for indicative purposes and by no means as of a limitation.
Referring to Fig. 1 and 2, there is shown an embodiment of a paper conversion dispenser machine according to the present invention generally indicated by reference numeral 10. The machine 10 converts a stock sheet-like material 22 into a continuous three-dimensional shape crumpled stream 23 of relatively low density cushioning dunnage product 24. The machine 10 is shown positioned standing vertical and includes a stock supplying assembly 20 with two stock paper rolls 21, a shaping member 30 that consists of a pre-entry section followed by an entry section 50, a guiding tunnel 60, a feed mechanism 70, a cutting set 80, and a frame 90.
As shown in_ Figs. 4 to 6, the pre-entry section 40 comprises two side entry guiding rollers 41, 42 having a substantially vertical axis and a bottom

6 PCT/CA01/01545 mounted roller 43 having a substantially horizontal axis. To better adjust to the paper quality, the two side entry guiding rollers 41, 42 have an inclination adjustment 44. Preferably, they are pivotally mounted at their lower end and secured in place via the adjustment 44, preferably a screw, to be adjusted within a plane defined by the two axis of the rollers 41, 42.
As shown in Figs. 1, 2, 4 and 5, the pre-entry section 40 is preferably slidably connected to the frame 90 via an attachment member 92. The latter preferably has a tightening screw 94 that allows for fixing the pre-entry section 40 at the required position. Furthermore, and with particular reference to Fig. 6, the entry section 50 also preferably consists of two side entry guiding rollers 51, 52 and a bottom mounted roller 53 having a substantially vertical and horizontal axis respectively.
As shown in Fig.7, the feed mechanism 70 drives the stock material 22 within the shaping member 30 and includes a motor 76 connected to a driving roller 72 and a driven roller 73 spring biased against the driving roller 72 via spring 74. Rollers 72, 73 are preferably made out of two coaxial wheels each, and are adapted to frictionally receive the dunnage product 24 there between.
Specifically, when sheet of paper 22 is pulled by the rollers 72, 73 of the feed mechanism 70 through pre-entry and entry sections 40, 50, the paper 22 is crumpled to form dunnage 24.
In the pre-entry section 40, the width of single or double ply stock paper 22 is preferably reduced by 70% into a narrower non-linear crumpled stream 23 of paper, from 30" to 10" approximately. The entry section 50 preferably reduces the width of_the ,crumpled ,stream 23 even ,narrower by an additional 30%, from 10" to 7" approximately, to a . relatively low density cushioning dunnage product 24. Two side entry guiding rollers 41, 42 and bottom mounted roller 43 of the pre-entry section 40, as well as the two side entry guiding rollers 51, 52 and the bottom mounted roller 53 of the entry section are preferably mounted on bearings for free rotational movement around there respective axis. Rollers 41, 42 ,43, 51, 52 and 53 are substantially so machined to provide a non-frictional surface finish and are preferably covered with an anti-friction material. It is also possible to slightly modify the shape of the dunnage product 24 by changing the inclination of the side rollers 41, 42 using the screw of the inclination adjustment 44.
, The pre-entry section 40 can be slidably adjusted to the required position by the attachment member 92 and the screw 94 to ensure optimal conditions of the cushioning dunnage product 24 movement for specific paper roll 21 quality and production rate. After the entry section 50, the cushioning dunnage product 24 moves through the guiding tunnel 60 to the set of driving and driven 73 rollers of the feed mechanism 70 to be pushed to the cutting set for cutting of the same and directly dispensing it into a shipping case or box containing products (not shown). The cutting set 80 preferably includes a sliding blade 84 driven by a second~motor 82 via a cam mechanism 86.
The paper conversion dispenser machine 10 of the present invention converts the sheet-like material 22 into a relatively low density cushioning dunnage product 24 with minimal friction, is extremely reliable to use and enables the production of cushioning dunnage product 24 at relatively high rate, without damaging the paper 22.
