Claims. (Cl. 154-30) This invention relates to corrugating machinesinclud ing the so-called single and double facer corrugators.
Machines for corrugating paper and adhesively bonding a lining or facing sheet to the apexes of the corrugations are. well known. The present invention has for one of its objects, the improvement of such machines, to maintain the corrugating rolls under constant controlled yielding pressure to obtain uniform fluting of the paper fed therethrough and this efficiently and economically.
Still another object of this invention is to provide such corrugating machine of relatively simple, compact, exceptionally rugged design.
Other objects and advantages of this invention will be apparent from the following detailed description thereof, taken in connection with the accompanying drawings which shows for purposes'of exemplification preferredv forms of this invention as embodied in single and double facer corrugating machines. It will be understood this invention is not limited to these embodiments.
Fig. 1 of the drawings is a side elevational view of a single facer corrugating machine.
Fig. 2 is a fragmentary vertical sectional view, on an enlarged scale, showing the mounting and fluid pressure applying means for the movable corrugating roller of a pair of rollers.
Fig. 3 is a diagrammatic plan view, including a circuit diagram of the pressure fluid system for placing the movable corrugating rollers of a double facer. corrugating machine under constant controlled yielding pressure. 1
Referring first to Fig. 1, indicates a roll of paper, from which the paper passes over a guide roll 11 and then over an adhesive applying roll 12 which receives adhesive from roll 13 rotating in a bath of adhesive 14 in container 15. An adjustable doctor blade 16 controls the amount of adhesive applied to the web 17 The adhesive coated web then passes around roll 18 into contact with'the corrugated web 19.
A roll 21 of paper 22 to be corrugated is suitably mounted in the machine. Paper 22 passes over a guide. roller 23 between the bite of a pair of corrugating rollers 24, 25. In its passage between the corrugating rollers 24, 25 the paper22 is corrugated-forming the corrugated web 19 which is bonded with the adhesive coated web 17, above described. The assembly is fed by the feed rollers 26 from the machine in the case of a single facer machine. In the case of a double facer machine, the assembly is adhesively bonded to a like assembly formed in the same manner.
As best shown in Fig. 2, movable corrugating roller 24 at each of its opposite endshas a shaft 26 journalled for rotation in the free end of an arm 27. Two such arms are provided, one for each end of the corrugating roller 24. The other end of each arm 27 is pivotally mounted on an eccentric sleeve 28, positioned for adjustable movement on the supporting pin 29 carried by the bracket 30. Each end of the movable corrugating roller 24 is similarly mounted, so that the ends of the movable corrugating roller 24 may be adjusted independently of each other by properly positioning the eccentric sleeve 28 individual thereto. Once the sleeve is adjusted, it is locked in place on supporting pin 29 by bolt or other suitable locking member.
In accordance with the present invention, each arm '27 at each of the opposite ends of the movable corrugating roller 24 has fixed thereto a bearing member 33 to which constant controlled yielding pressure is applied as hereinafter described. As the construction at each end is the same, only one will be described in detail. The bearing member 33 is positioned, as shown in Fig. 2, so that its axis 34 is in alignment (straight line) with the diameter A 35 of the circle delineating the cross .section of the movable corrugating roller 24. Bearing member 33 is provided with a cylindrical seat 37 in which seats the base portion of a pressure transmitting steel ball or sphere 3 8.
A pressure cylinder 39 has slidably mounted therein a piston 40. The base of this piston 40 is provided with a cylindrical seat 41 for receiving the upper portion of ball 38. Cylinder 39 has at its top a seat 42 for the base portion of a steel ball or sphere 43, the upper portion of -which is disposed in a seat 44 on the frame 45 of the machine. Pressure cylinder 39 is thus maintained in the machine, the balls or spheres 38 and 43 and their coopcrating seats in eifect form universal joints which enable pressure to be transmitted at right angles to the length of the movable corrugating roller, always directly along a line coincident with the diameter 35.
'The diameter 35 intersects the area where the ridges on the movable roll 24 mesh with the valleysbetween the ridges on the fixed roll 25. This area is indicated by the lines c-c on Fig. 2. Thus, the pressure applied by piston 40 is at right angles to the axis of both rolls 24 and 25 linearly along a line intersecting the area where'the two Stated otherwise the pressure is applied. at the point where a" corrugating rollers are in meshing agreement.
valley of movable corrugating roller 24 is filled with a projection of roller 25 as the two rollers rotate, which point is indicated by 50 on Fig. 2.
Desirably, cylinder 39 has near its base lubricating inlets 53 1 -Each cylinder 39 communicates .with an accumulator. Thus, .in the case of a double facer, involving two movable corrugating rollers, as shown in Fig. 3 four pressure fluid cylinders 39 are employed, each individual to one end of a movable corrugating" roller and each connected by a pressure line 55 withian- 54 individual thereto.
The accumulators may be of any desired type main-x taining a'constant pressure of fluid on piston 40 ofpre'slators are employed, in which the bladder divides the accumulator into two compartments, one of which receives air or other gas under any desired pressure and the other compartment contains a lubricating oil or other pressure fluid under the pressure in the first mentioned compartment. Examples of such accumulators are dis- Patented Nov. 15, 1960 p 3 closed in-United'States Patents Nos. 2,484,418, 2,786,488 and 2,801,067.
The pressure fluid system shown in Fig. 3, involves a pump. 56 actuated by. a motor 57 for pumping oil or other pressurefiuid into tank or reservoir. M to maintain it.
under any desired pressure; A pumpvpressure gauge 58 communicates with tank M through line 59 having valve 61 therein. Tank M, communicates with a main header 62 provided with branch lines 63, 64, 65 and 66, each valve controlled, provided with a gauge 67' and communicating with the accumulators 54.
It will be noted each accumulator has one of the branch lines 63, 64, 65 or 66 individual thereto and thus the pressure in each accumulator can be adjusted independently of the others. The pressure thus imparted to each accumulator is transmitted to-the end of the movable corrugating roller 24 as hereinabove described; this pressure is applied to the end of the bearing member 33 on arm 27 in which shaft 26 of the accumulator roller 24 is journalled. The pressure is applied at right angles to the axis of the accumulator roll in a linear direction at point 50 of the drawings.
Once the machine is set for a desired pressure, the
pressure remains constant, but yielding (due to the fluid.
pressure used) to accommodate variations in, the paper stock, etc. When changing paper stocks, adjustments can readily be made inthe pressure, by operating pump 56,
if necessary and opening appropriate valve or valves in.
An important feature of the present invention is. the mounting of the. cylinders 39. Spheres 38 and 43 in the seats 37 and 41 (for sphere 38) and seats 42 and 44 (for sphere43), maintain thepiston 39 so that at all times it exerts pressure linearly. along diameter 35 and at point 50. This pressure once set, is constant but yielding- Hence, for any given paper stock, it may be set to" give optimum fiuting or corrugating of that stock.
ilt will be noted the present invention provides a, corrugating machine of simple, compact and exceptionally rugged design..
Since certain changes may be made in the above described corrugating' machine andv difierent embodiments of the invention could be made without departing from the scope thereof, it'is intendedthat all matter containedin the above description or shown in the accompanying drawings shall beinterpreted as illustrativeand' not in a limiting sense.
