DEVICE FOR HOLDING ROLLS OF IPAIER.
Application mea m 5,
The invention relates to devices for holding rolls of paper and the like.
In the operation of machines to which a strip of paper is fed from a large supply I roll, such as a machine for making faced corrugated board, a desideratum has been to avoid the stoppage of the machine or lack of supply incident to the removal of the empty spools and placement of full rolls in feeding position. The primary object of the present invention is to provide a device by which a full roll may be placed in its operative osition, before the roll from which the ma hine is being supplied has been run 15 off, and in readiness to be threaded into the machine without interrupting the supply.
In general, this device embodies means for temporarily supportin a full roll in one position in readiness to be fed to the machine 20 without interruption of the supply, and means for transferring the full roll to the normal position of the supply roll while it is being run off and after the empty spool has been removed. Another object of the invention is to provide a device of this character by which the paper will be constantly kept under the desired tension to prevent overrunning.
The invention consists in the several novel features hereinafter set forth and more particularly defined by the claims at the conclusion hereof.
In the drawings: Fig. 1 is a side elevation of a structure embodying the invention, showing a full roll in its temporary position in readiness to be supplied to the machine while the roll from which the paper is being run, is nearly empty. Fig. 2 is a similar view showing the transfer mechanism in position to transfer the full roll to the normal operative position of the supply rolL Fig. 2" is a detail of the pocket-bearings in the supporting frame. Fig. 3 is a front elevation. Fig. 4 is a section taken on line 44 of Fi 2. Fig. 5 is a detail of the braking or retar ing device.
The invention is exemplified in a structure comprising a supporting frame composed of similar sides 7 which are rigidly crossconnected by a rod 8, and are adapted to rest upon the floor.
Adjacent their rear ends the frame sides 7 are provided with aligned recesses which form open or pocket-bearings 9 for a shaft 55 10, which is usually provided with cones 11 1924. Serial No. 724,205.
to form a spool or reel on which the paper 12 1s wound, is adapted to rest and run in and to be lowered into and be raised out 0 said bearings. The shaft of each roll of paper is supported and held in bearin s 9 whlle the roll is being unwound by the eedrolls of the machine to he su plied with paper. Each shaft 10 is providsd adjacent one end, with a grooved pulley 13 for a friction or braking device which sufliciently retards the rotation of the shaft to prevent the roll from overrunning or to apply the desired resistance to the paper accordin to the requirements of the machine supplied Each braking device consists of a ring fitting 1n the pulley 13 and formed of sections 14 and 15 which are hinged together, as at 16. A screw 17 is provided with a shoulder 18 engaging a perforated lug 19 on ring-section 14 and is threaded to alug 20 on ring-section 15 to hold the ring-sections on the pulley 13. Suitable brake lining 21 is secured to the inner periphery of the ring-sections. By adjusting the screw 17 the friction of the ring on the pulley may be regulated to put the desired tension on the paper. A pair of arms 22 and 23 project from ring-section 15 of the brake-rlng and are adapted to engage co-acting stop-pins as hereinafter set forth.
The supporting frame is also provided ad"- jacent its front end with aligned recesses 24 which form open or pocket-bearings for the shaft 10 of a second paper roll. These frontbearings are positioned to hold a full roll before the supply roll held in bearings 9 has been run off. The stop-arm 23 on the braking device of a shaft held in bearings 24 will enga e a stop-pin 25 projecting from one of the rams-sides 7 so that while the roll is being thus supported: the desired friction will be applied to the paper to prevent it from overrunning or to put the desired tension thereon according to the requirements of the machine to which the paper is supplied. The supplemental bearings 24 make it possible to have a full roll in readiness to be threaded into the machine as soon as the roll carried in bearings 9 is empty and consequently there will be available an uninterrupted supply of paper. Each shaft 10 is provided with a series of annular grooves 27 which when the shaft is placed in bearings 24, receive the teeth of a pinion 28 which is mounted on a shaft 29 carried in a bearing 30 on one of the frame-sides.
This shaft 28 has a polygonal end 30 so 7 from bearin s 24 to bearings 9, after the roll carried y the latter is empty and its shaft 10 has been removed. This mechanism comprises a transverse rockable shaft 32 which passes through bearings 7* in the frame-sides 7 and a pair of lifting arms 33 which are rigidly attached to said shaft. A tiltable transfer-device which is adapted to transfer a shaft 10 with a roll thereon from bearings 24 to bearings 9 while the roll is being run off into the machine, comprises a shaft 34 which is pivotally mounted in the distal ends of lifting arms 33 and a pair of transfer arms 35 fixed to shaft 34. The upper end of each arm 35 is forked as at 35 to straddle and hold a shaft 10 during a transferring operation. An operating arm 36 fixed to shaft 34 is adapted to slip into and be shifted by a long piece of pipe serving as a lever. An operating arm 37 is rigidly fixed to shaft 32 and is also adapted to pass into and be shifted by a long piece of pipe or lever. The frame-sides 7 are provided with aligned open bearings or recesses 38 and 39 which are adapted to support the shaft 34 in two alternative positions. The forward swing of the arms-35 is limited by a stop-pin 7 b so that in transferring a roll to bearing 9 the transfer arms will be arrested in correct position to deposit the roll-shaft 10 in bearings 9.
A stop pin 40 is provided on one of the arms 35, which when the arm is lifted 'to transfer a rolleshaft 10 in bearings 24, will pass into position to engage arm 22 of the raking device to prevent the roll from unwinding while its shaft is being sustained and transferred by the transfer arms 35 to bearlngs 9.-
The operation will be as follows: I
A shaft 10 with a full roll of paper there on will be placed into pockets 24. The brake-arm 23 on the brake-ring carried by said shaft will engage the stop-pin 25 on the one of the frame-sides 7, while the shaft remains in pocket 24, so that the paper will be kelpt under proper or necessary tension to supp y the machine. The paper may be connected to supply the machine as soon as this roll is held in pockets 24. While the paper from this roll is being drawn into the machine, its shaft 10 will be trans ferred to pockets 9 without interruption in the paper supply. This transfer is effected by first rocking shaft 34 into the position s own by full lmes in Fig. 2, bymeans of a lever applied to arm 36. Then arm 37 of the arm 22 to keep the paper under tension during its transfer. A ever will then be applied to arm 36 to swing the transfer arms 35 together with shaft 10 and its roll into position shown in full lines of Fig. l and so that the shaft will rest and be rotatable in pockets 9. The front ends of said pockets are inclined to permit the shaft 10 to be swung into said pockets by arms 35. One side 35 of each fork 35 is cut away to permit the fork to pass under a shaft 10 in pockets 24, the other side being adapted to be arrested by the shaft. This transfer is accomplished without interrupting the paper supply. The transferred roll will be completely run off while its shaft remains in pockets 9 and arms 35 remain connected thereto. Before this roll is exhausted, a full roll will be placed in pockets 24 in readiness to be connected to the machine the instant or before the supply from the roll in pockets 9 becomes exhausted. Next the empty shaft 10 will be removed from pockets 9 and the roll will be transferred from pockets 24 as before described.
The invention exemplifies a mechanism for handling rolls of paper whereby a full roll may be successively placed in readiness to supply a machine and then transferred into position to be run OE; and in which provision is made for braking the rolls at all times and during the transfer thereof.
The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the a pended claims, without departing from t e spirit and scope of the invention.
