DEVICE FOR FEEDING AND ADJUSTING- IPAPER SHEETS.

Specification of Letters Patent.

Patented Feb. 3, 1920.

Application filed December 28, 1915. Serial No. 69,047.

To all whom it may concern Be it known that I, GEORG SPIEss, a subject of the German Emperor, and a resident of Leipzig-Reudnitz, Saxony, have invented certain new and useful Improvements in Devices for Feeding and Adjusting Paper Sheets, of which the following is a specification.

My invention relates to devices for feeding and adjusting paper sheets and the particular object of my invention is a paper feeding and adjusting device of superior efficiency.

Paper feeders such as used for instance in paper assorting machines are generally provided with gripping devices consisting of two endless parallel chains carrying between them bars serving as gripper carriers, such bars being distributed over the length of the chains at a certain distance from each other. Now the space between the two chains must be free of all obstacles in order to allow the gripper bars a free passage. Moreover the gripper bars themselves are a very disturbing element in paper assorting machines and the like, especially so at the point where the operator controls the passage of the sheets, 'as this control is continuously disturbed by the bars passing across. Besides ,this, the distance between the gripper bars must of necessity correspond to the largest size of sheets to be fed by the machine, and

in consequence thereof, in feeding smaller sheets, if the distance between the grippers remains unchanged, the space between the single sheets will continually increase. -Consequent] y the useful work done by the, ma-

chine will he the less, the smaller the size of the sheets to be fed.

Further the observation of the sheets is impaired by larger intermediate spaces between the single sheets, the eye of the observer being disturbed by the quick succession of the white sheets and the dark spaces of. great dimensions;

In feeders heretofore employed these disadvantages were adjusted by altering the distance of the grippers in accordance with the size of the sheets; bydoing this however the capacity of the -machine is severely handicapped, all'altera'tions of. this kind requiring much time. Y

In the machine forming the subject matter accordingto the present invention all these defects are overcome by arranging on both sides of the path of feeding endless of the sheets,

transporting chains running in the same d 1rect1on,such chalns serving at the same t1me as carriers of the grippers. WVith this machine sheets of any slze can be fed through the machine without necessitating any change in the arrangement of the chains or grippers and without altering the distance betweentwo sheets in accordance with their size.

The invention is illustrated in the accompanying drawing embodying in desirable form the present improvements. 1

matter whether the sheet is long or short;

7 according to its length the sheet is gripped and held by a smaller or greater number of grip ers on each side. The distance between tile two'rowsof grippers is absolutely free of all obstacles, and the eye of the 'operator who has charge of the supervision and assorting of defective sheets canrest undisturbed upon the sheets.

In the form of device shown in Figs. 1 and 2 each sheet 5 is fed into the machine by the feeding rollers 6 and 6" and then enters immediatelyinto the first two grippers 2 and 2". After these grippers are closed automatically and carry the sheet along, the fol "lowing grippers in approaching this point 5 are opened by a mechanical device of wellknown construction in order to grip the same shee't in another place and so on, until the sheet has been gripped by 'a number of grippers all over its length and is freely carried away by them. ,In this manner the sheet is transported across the point of control 7 in order to be then deposited on the pile 8, if it had proved. to be inferior in I quality, or on pile 9, if it had been found to be free of all deficiencies, p

The laying down} of the sheets grippers carrying the sheet being opened simultaneously. To this end cam bars 10,

' .10 and 11, 11 are movably' located onboth sides of the grippers, said bars being provided with

cams

12 and 13. Whenever the shanks of the'grippers meet these cams, the grippers are opened simultaneously and the sheet is free to fall down by its own'weight. In order to pick out defective sheets the cam bars 10*, 10 can be displaced by the operator by means of a hand lever in such a way as to effect theopening of the grippers only in casethat defective sheets are to be deposited on pile 8*, while in all other cases "the grippers are only opened by the bars 11*,

can be. effected by hand or mechanically, all the' 11 in their position of rest, the sheet being then deposited on pile 9.

Of course, the chains carrying the grip-- width. This can be efiected for instance by displacing the axial bearings of the

pulleys

3 and 4 on a common screw spindle; by rotating said spindle the distance between the two pulleys can then easily be varied. The screw spindle arrangement may of coursebe replaced by any other suitable arrangement.

The position of the pulleys 4, 4-of the other chain can be such that they are disposed in a horizontal plane. However they may also be inclined or the planes of the

pulleys

3, 3 may be disposed vertically but parallel to the

ulleys

4, 4.

In the modi cationtrepresented in Figs. 3

and 4, the pulleys and chains are disposed in .vertical planes and the pulleys of one side are parallel to the pulleysof the other side. This arrangement is preferable for the reason that it requires less room, the returning chains or ropes running below the effective chains or ropes.

In the device for opening and closing the grippers at the point of introduction of the sheet, as shown in Figs; 5 and 6, the chain 1 carryingthe grippers runs over a pulley 3 and carries the gripper 14. The pulley 3 is provided with a curved guiding rail 15. The gripper itself consists of two plates or shanks 16 and 17 pivotally connected with the body 14 and normally held in closed position by a spring18 located within the gripper body. The closing is effected by a sleeve 19 displaceably disposed on the gripper body 14 and adapted to be carried along by a pm 20, against which the spring 18 is resting, said sleeve 19 effecting the closing of the gripper plates 16' and 17. The sleeve 19 is displaced against the action of spring 18 by means of a bell crank lever 21,

one arm, of said lever embracing the pin 20 with a slot, while the other arm is running against the curved rail 15 on the pulley 3 whenever the gripper is in the initial position. The running of the lever arm against the curved rail causes the toggle lever 21 to be oscillated and the sleeve 19 to be pulled back against the action of the spring 18 and the plates ltl and 17 are opened, one of them by its own weight, the other one under the action ofspring 22. As soon as the chain 1 leaves the pulley 3, the bell crank lever 21 gets free of the rail and the gripper is. closed by spring 18 (Fig. 3).

The moment of openlng and closing the grippers can befldetermined by simply displacing the pulleys 3 on their axles or by employing displaceable curved rails 15 on said pulleys. Another and more effective device for varying the moment of opening and closing the grippers within wider limits is shown in Figs. 7 to 9, said device being especially applicable to the gripping device represented in Figs. 3 and 4. The means for closing the grippers are a short plece of a chain 23 running over

pulleys

25 and 27 and having fastened to one end a steel band 24 running over a pulley 26. The outer hnks of the chain are U-shaped (Fig. 9), and 1n those places where the chain runs in a straight line, the outer edges of the links are all in one plane. The curved guidmg rall 15 is not rigidly fixed to pulley 3, but is disposed sidewise of it and the end of said rail which is directed toward the chain 23, runs in a plane with theouter parts of the links of this chain. The free arms of the bell crank levers'21 fastened to the gripper bodies are connected with the guiding rail 15 and then with the outer parts of the links of chain 23 until they arrive at the end of this chain. At this moment they are left free and the grippers are closed under the action of springs as described above. A stationary fiat rail 28 is arranged in a suitable way behind the chain links 23 so as to take up the counterp'ressure of the arms of lever 21. If it is desired to have the grippers closed sooner or later, a mere turning of the axle 29 carrying the steel band pulley 26 will vary the position of the last link'of chain 23.-' To this end the axle 29 is preferably provided with a prismatic end allowing a crank handle to be affixedto it.

. By employing a displaceable guiding chain as described the moment of closing the grippers can be varied within wide limits without requiring much space. In those cases where much free space is available, a variability within wide limits may be obtained by aflixing, to the free arm 15 of rail 15 prolongations of different length or by composing said arm of two parts and arranging the prolongation rail immediately on arm 15;

As herein mentioned the feeding by means of grippers such as describedallows the sheets to follow each other in immediate succession independently of their lengths, thus securing a uniform capacity of the Further the observathrough the machine is materially facili tated, no gripper bars being provided which could run over the sheets. The adjustable closing rail allows of increasing the distance between each two sheets if necessary,

this being especially important with sheets of light paper and of large size, such sheets requiring a certain time for falling down at I the end, beforethe way is clear for the next sheet to follow. r

If the feeding devlce herein described is used for sorting out defective sheets from a said strip being continuously controlled by the grippers and being gripped by them before the cross-cutter has cut the sheet off the paper strip. This arrangement is especially effective in case the cross-cutting knife is arranged immediately in frontof the gripping device and one sheet fol-lows the other.

In machines heretofore provided with gripper bars, the sheet cut off by the crosscutter falls upon a transporting device carrying it to the gripper bars following each other at a certain distance and carrying the sheet across the point of observation down to the piles of good or defective sheets. The transporting device mentioned is usually a band transporter serving as aconnecting member between the cross-cutter and the grippers in order to make it possible to feed all sizes and thus to avoid the,

light weight paper. The primary cause of this damaging of the sheets is the high speed imparted to the sheets and also the draft created by the sheets moving at high speed, the sheets being thereby frequently prevented from resting against said catches in a correct position. All this is a cause of frequent failures in the adjusting of the sheet. Any sheet, however, which is gripped by the gripper bars withouthaving been well adjusted will be torn to pieces during its further transportation. The number of defective sheets is still higher with smaller sized sheets because the smaller weight of these sheets will cause them still more frequently to be displaced on the transporting bands. Said band transporter must further have a size sufficient for the greatest length of sheets, and in consequence thereof the. length of said transporting device is from 5 to 7 feet. All this can be avoided if such a transporting device can be dispensed with. This can be effected by employing a device such as shown in Figs. 10

to 12, said device preventing the sheet from leaving the grippers after it has been cut o q The endless paper leaving the roll a is carried across the cylinders Z) to the transporting cylinders c which are feeding it to the lengthwise cutter d alt. After the paper has been cut lengthwise, the ihalves are.

defective sheet pile or to the pile where the good sheets are deposited. The grippers 2*, 2 are carried'by endless chains 1 1 running around pulleys 3, 3. The grippers are further supported by guide rails lb, 7.2, on which the grippers roll.

Whenever the operator has observed a deficiency in the paper, he presses the hand lever 1 down, the end Z of said lever being connected with a connecting rod m transferring said movement to a bell crank lever n pivoted to a bolt 0 and in being turned oscillating the bell crank lever 51 arranged on the bolt 9 by means of the connecting rod 1) This causes the lever 1", provided with a roller and turning around bolt 8, to be released and toapply-its roller 11 under the action of the spring u against the cam disk t. When the sheet arrives at the point where the defective sheets are deposited on'their pile the roller r is pressed by the spring u into an indenture of the cam disk t and the arm 1* of the lever 1' is moved downward.

' The connecting rod 'v transfers this movement to a lever w turning on a bolt 41 and connected with a rod y pivoted to bolt 2 of the lever A thus causing the opening bar A to be lowered, said bar hanging on the oscillating arms A and A arranged on pins A and A When the opening bar A is lowered, the levers G of the grippers 2, 2 to be described hereinafter are pressed out-ward so as to cause all the grippers 2', 2" which are still below the opening bar A', to ble. opened and to release the respective s eet.

I By means of another connecting rod B the I lever w also displaces the gripper closing cam B carried by the oscillating arm B loosely mounted on the shaft A and by a bell crank lever Bi loosely mounted on shaft B .Thus the turning movement mentioned, of cam disk t causes the openlng bar A to be lowered and the gripper'closing cam B to be lifted simultaneously so that duringthe moment when the grippers are opened, the gripper closing cam isput out of action.

' -A push-arm (J fixed. on a shaft 02 is oscillated by said shaft in a vertical direction and causes the sheet to upon the pile.-

The good sheets are laid off by me-ms of a cam disk H fixed on the rotating shaft W and acting upon a roller lever H pivoted fall quickly down to a bolt H A connecting rod J and an opening bar J? hanging on the oscillating arms J, J 4 are displaced by means of a bell crank lever J fixed to the shaft J said shaft also carrying a push-arm J G lowered simultaneously with the opening of the grippers.

'Thegrippers 2, 2 consist of two movable gripping plates G G (Figs. 16 to 18). The upper plate G is pivoted to a bolt G andits hub forms a toothed segment which ears with the teeth of a toothed-segment 4 pivoted to a bolt G The lower gripping plate G which is pivoted to the bolt Gr as toothed segment G. in such a way that when this segment is oscillated, the two gripping plates are moved in opposite directions. The segment. isdisplaced and the gripper is closed by a roller bolt Gr pressed downward when its roller G is rolling on the closingcam B. On the roller bolt G bein lowered the spring G is compressed unti the catch-lever G acted upon by spring G catches the toothed segment G The grippers are opened by the opening bars A and J being lowered upon the free end of the catch=lever G thus causing its pawl to release the segment lever G1. Thereupon the compressed spring Gr will press the upper gripping plate G upward, while the lower gripping plate G is pressed down- Ward by means of the link G.

13 and 14. With this cutter defective sfiiets are cut off the moving paper web or strip after the cutter has made a half revolution, so that only short portions are deposited on the defective sheet pile. The cross-cutting knife thus actuated-before a fulllength of a sheet has passed and in half the time'hitherto required for it by the hand lever .1 may be arrange'd to work simultaneously with the push-arm C and the opener A If for instance a leverD pivoted to a bolt D is arranged on the bolt m? of the connecting rod m, by lifting said ispressed downward and the roller lever E is applied under the influence of the spring E to the cam disk K fixed on the shaft W The shafts W, W and the shaftsW herein mentioned make the same number of revolutions, At the other end of the roller l onnecting 'i'odthe other end of the lever The cross-cutter carrying lever arms have a longitudinal slot allowing the lever arms to be shifted laterally on the shaftM by means of the keys M. A forked lever M is pivoted to a bolt M fixed to a bearing M the forked end of said lever embracing the rotating knife lever and being provided at its other end witha roller M running in the curved slot of the cam disk E VVhenever the connecting rod E is moved upward, the curve of the cam disk moves through a certain angle on, the shaft E the cam slot causing the forked lever M to be displaced and the levercarrying the knives to be displaced sidewise on the shaft M so as to cause the second knife M to cut the paper when the shaft M has made a .half revolution. In this way only half a sheet is cut off and carried to the defective, sheet pile.

This cross-cutting 4b arrangement offers the advantage of furnishing a larger number of good sheets.

In order to provide that the cutting-off operation and the operation of closing the grippers are effected substantially at the same moment, a number of'difl'erent arrangements may be made. Instead of using the device shown in Figs. 6 to 8, an adjustable gripper closing cam may be employed, such as shown for instance in Fig. 15. In

1 this device the gripper closing cam B is suspended on the oscillating arms B and B only indirectly, a rail B being pivoted to J said arms. The gripper closing cam B? is adapted to be displaced in, a horizontal direction on a bar B" carried by said rail B a clamping screw or the like being provided for securing it in its position. According to whether the cam B is displaced to the right or to the left, the grippers 2 2 are closed earlier or later and it is possible, with this arrangement, to regulate the closing of the grippers so as to bring it in accordance with the size of the sheets.

A full effect of an adjustable gripper closing cam as described, however, only is After *this has been effected, 30 ,the knife M will cut the paper only after obtained in case the velocity of the grippers is rendered variable also. If the distance between two succeeding sheets must be'made greater or smaller, the velocity of the grippers must be varied as well-in order to cause each sheet, which has been cut off to be carried away so quickly that. the predetermined distance is obtained. If the velocity of the grippers is varied, it is also necessary to vary the closing movement of the grippers which are the first to act upon the sheet. This is effected first by making the gripper closing cam adjustable. The variability of the velocity of the grippers can be obtained by different devices, one of said devices being shown in Figs. 19 and 20.

In this device the chain wheels .3 carrying the gripper chains 1 are driven 'by .a'change gear arranged within a casing 30. The

change

wheels

31 and 32 are coned toothed wheels. A hand lever 33 serves to throw in either one or the other gear, the special construction of the change gear and the means for throwing it in being of no avail as far as this invention is concerned. A variable friction gear. of some well-known type may be employed as well. By adjustresponding to the velocity of the paper.

On the other hand, if the closing of the mg the gripper closingflcam in such a mangrippers only takes place at approximately the same moment as the paper is being cut off, and if the velocity of the grippers is a little greater than that of thepaper, then the desired spaces between the single sheets are obtained.

The capacity of a device for assorting defective sheets as herein described is dependent, apart from the normal velocity. of observation, merely from the velocity of the paper. The highest capacity is obtained, if the place of observation is arranged in front of the cross-cutter as herein described, because the velocity of the papercan be increased as far as the observing capacity of the operator goes. c

f on account of economy of space or for other reasons the. place of observation is located behind the cross-cutter and the observing shall be done across the grippers,

the arrangement described can be used, if

the paper allows of transporting one sheet after the other without leaving any spaces between the single sheets. On (the other hand, if light weight paper webs shall be cut in the machine or the sheets are of large size and require a certain time for being deposited on the pile, thenintermediate spaces of a certain size have to be arranged between the successive sheets.

In consequence thereof the capacity of a device having the place of observation arranged above the path of the grippers would be less in accordance with the size of the spaces between the sheets, provided that the velocity of observation is the nor device shall be given the same velocity as. -thepaper in view of another place of ob mal one.

21 and 22 and designed for'ob'serving the sheets from both sides. In this case two places of observation are provided, one in front of and the other one atthe'rear of the cross-cutter. The paper strip or web runs from a cylinder 0, across a reversing cylinder a and between these two cylinders the first place of observation is arranged. The path of the' paper is then identical with the one described before. If the gripping servation being arranged above said device,

.and if spaces shall be provided between the successive sheets in order to have-sufiicient time for depositing the sheets, then the velocity of the gripper device must be increased after the sheet has been cut off by the cross-cutter; this" can be effected for instance by means of the following device for driving the chain wheels 3.

Y the cone wheel 39 is in gear with the .cam

slot of a cam disk 41 fixed on a shaft 50, said shaft bein driven from the main shaft W by means o toothed wheels 34, 35, By turning the cam disk the. cone wheel 39 is 'kept in its normal position, as long as the.

roller 40 is running in the circular part of the slot. However as soon as the roller enters the curved part of the slot, the carrier of the cone wheel. 39 is caused to effect a turning movement on the shaft If this movement is effected in the direction of rotation of the cone wheel 37, the move-' ment of rotation of this wheel and the movement ofthe grippers is accelerated. When the cone wheel 39 returns to its initial po sition the ripping device receives its normal velocity which may correspond to the velocity of the paper strip or web. By this means, whenever-a fresh sheet is fed,its transporting speed is intermittently varied at the desired mom.ent and this variation of speed'i's stopped immediately thereafter This defect can however be avoided by using the device shown in Figs.

the grippers.

' l as soon as the sheet to be observed is passing the second place of observation.

In order'to allow the spaces between the sheets to bevaried, the driving device may be constructed as shown in Fig. 23. In this modification the cam disk 41 does :not act upon the cone wheel 39 directly, but by the mediumof a double-armed lever 42 having a link 43 displ aceably arranged at its free end. The said link is-linked to the carrier of the cone wheel 39 and also to a sleeve 45 displaceable on the free end of the lever .42 and adapted to be fixed to it by means of a setscrew 46. If the movement of the cam disk is transferred by means of these links 42*and 43 upon thecone wheel 39, then. the turning movement of the cone wheel 39 on the shaft W is variedaccording to whether the link 43 is fixed in a position nearer to or farther away from the pivot 44 of lever-'42. By varying the turning movement of the cone wheel 39 the velocity of the sheet transport and the distance between the successive sheets also is varied. I v

The device described can of course be employed also in connection with a machine allowing only a one-sided observation of the sheets. ,The highest possible output of the paper sorting machine provided with all these improvements is obtained notionly as far as the numberof sheets is concerned, but also with regard to the weight of the sheets.

-Tlie sheets can follow each other immediately without any spaces being left between them or else a space may be left between each two successive sheets such as is required for safely depositingeach sheet. In every case the maximum capacity of the machine can be obtained in accordance with the different kinds of paper to be assorted without requiring any" variation in the. velocity of observation.
