Application April 17, 1941,561'181 No. 389,001
3 Claims. (01. 91-18) This invention relates to devices for feeding web material and has for its object to provide a.
new and improved device for this purpose.
In feeding web material to certain processing machines, such as waxing machines, coating machines and rotogravure printing presses, it is desirable that the machine be capable of operation while the web is threaded through it, without having the web itself move, thus avoiding waste material while the machine is being cleaned or while the wax, coating or ink is spread evenly on the cylinder from which it is applied to the web of material, or while corrections are being made on the cylinder in connection withrotogravure printing. One of the objects of the present invention is to provide means for securing these results.
The invention has as a further object to provide means for feeding web material to the ma-- chine with which it is used and controlling its tension. The inventionhas as a further object to provide means for feeding web material to the machine with which it is used, so as to have uniform. belt feed regardless of the diameter of the cylinder which applies material to the web.
The invention has other objects which will be more particularly pointed out in the accompanying description.
In the drawings,
Fig. 1 is adiagrammatic view illustrating one form of the invention;
Fig. 2 is a detail of the connection between the roll which engages the web and its driving 7 shaft.
Like numerals refer to like parts throughout the several figures.
The processing machines used in connection with the present invention may be of various types and I have illustrated a processing machine generally comprising a tank I and a cylinder or roll 2, mounted in position to receive material from the tank I which isto be applied to the web 3. In some instances there is a rubber covered roll 2a interposed between the roll 2 and the web 3. This roll 2a may be omitted when desired.
There is a roller 4 which engages the web 3 and presses it toward the roll 2a and the roll 2, so that the material on the roll 2 will be transferred to the web either directly or through the roll 2a. The web 3 as herein shown is yvound in the form of a roll 5 which is preferably mounted upon a reel 6 having a plurality of arms 1. The web 3 after leaving the roll 5 passes over the rolls III, II, l2 and I3 and thence over the roller 4, or roll 2a, where the material from the roll 2 is transferred to it. The delivery of the web from the roll 5 or from any roll on the reel, is controlled by a belt I 4 which passes around pulleys I5 and I6, and thence around a pulley II, which by the pressure means is automatically adjusts the pulley I! to maintain a constant pressure of the belt I 4 against the roll 5 as it decreases because of the unwinding of the web 3. The belt then passes around the driving pulley I3 and the direction changing pulley 20. I have 11'' lustrated one belt in the-drawings, but there will generally be a plurality of similar belts engaging the roll, the number depending upon the width of the roll.
The web 3 is pressed against the roll 2a, or the roll 2 when the roll 2a is omitted, by the roller 4. This roller drives the shaft 2| through the agency of the beveled gears 22 and 22a. This driving connection is such that the roller 4 may be moved away from the roll 2 so as to separate the web 3 therefrom, as will be hereinafter explained. The shaft 2| drives the shaft 23 through the beveled gears 24. The shaft 23 through the beveled gears 25 drives the shaft 26 of the belt driving pulley l9. I
It will thus be seen that the belt l4 which controls the web 3 and regulates its speed is driven by means of the contact of roller 4 with roll 2, either directly or through the roll 2a and that when the roller 4, or when roll 2a is used, the roll 2a, is mov'ed out of contact with roll 2, the web is moved out of contact with the roll 2 and movement of the web ceases.
Any suitable means may be used for moving the roller 4 so as to stop the movement of the web 3. In view of the fact that the roller 4 has a gear driving connection 22 and 22a with the shaft 2|, I have shown a construction where the gear 22 is connected with the shaft 2| by a spline 28 and is slidable on this shaft. It is connected to the shaft of roller 4 by the member 29. I prefer to provide the roll 2a preferably of rubber, or covered with rubber or other similar material, between the roller 4 and the roll 2 and around which the web 3 passes. With this construction the roll 2a is connected to the roller 4 so that they may be moved together away from the roll 2 so that the web 3 will be out of contact with the driving roll 2 and cease to move. Any suitable means for accomplishing this result may be used.. I have shown a simple construction for this purpose wherein the roller 4 and the roll 2a are moved by means of an air cylinder 33 provided with a piston 3|, the air cylinder being preferably connected to the same air system used in connection with the pressure means It. Air is supplied to the pressure means l8 by the supply pipe 33 and there are connecting pipes 34 and 35 connected with the cylinder 30 on opposite sides of the piston 3|. There is a four-way valve 32 arranged to control the pipes 34 and 35. There is an exhaust pipe 31 through which the air from the cyldriven from the surface of the roll and therefore always takes on substantially this surface speed, regardless of the size or diameter of the roll.
inder may be exhausted on one side of the piston,
so that the pressure on the other side will move the piston. Connected with the piston is a lever 33 which is pivotally connected by a loose connection with the member 29 which slides on the shaft 2|. The lever 38 at its other end is connected to any fixed point.
When it is desired to bring the web 3 into contact with the roll 2, the valve 32 is manipulated so that the piston 3| is brought to the lower end of the cylinder. roller 4 and roll 2a downwardly so as to move the web 3 passing around roll 2a into intimate contact with the roll 2, by means of which it is driven. There is preferably a loose connection between the shafts of roller 4 and roll 2a, which is herein shown as a link connection 362:, see Fig. 2. When it is desired to stop the movementof the web 3 the valve 32 is manipulated so that the piston 3| is moved toward the upper end of the cylinder 30. This causes the lever 38 to lift the roller 4 and roll 2a so as to move the web 3 out of contact with the roll 2 which is driving it and thus stop the motion of the web 3. Any slack in the web 3 is taken up by the spring 38 associated with the roll II. In all of these positions the gears 22 and 22a remain in engagement. When the web 3 is out of contact with the roll 2 the movement of the shaft 2| and associated parts is stopped. When the web 3 is moved into contact with the roll 2 the shafts 2|, 23 and 26 are rotated so as to rotate the belt I4 and this causes the roll 5 to be rotated to unwind the web 3, the web having transferred to it the ink or color or other material applied to the roll 2. I have shown the web 3 as bein below the roll 2a, but it might pass above this roll and between it and the roller 4, the ink or other material being transferred to it from the roll 2 by the roll 2a.
The roll 2 is driven in any desired manner, as by means of the shaft-39. In printing presses and the like this shaft 39 is preferably driven from the press shaft. It will be seen that in this construction the web 3 is not driven by the press shaft, that is, by a shaft drive, but is driven by a surface drive, that is, the surface of the roll 2, so that the web is always properly driven at the proper speed regardless of the variation in size or diameter of the roll 2. It will thus be seen that as this roll changes in diameter nothing further need be done to secure the proper speed of the web, for it is automatically taken care of by the fact that the web is The lever 38 then moves the In order to bring out the essential features of the device I have omitted the frame for holding the bearings for the different shafts and supporting the different parts, showing the essential elements in an more or less diagrammatic form so that their construction and operation may be easily understood.
