EDWIN IMO REY, OF NASHUA, NEW HAMPSHIRE, ASSIGNOR TO IMPROVED PAPER MACHINERY COMPANY, OF NASHU'A, NEW HAMPSHIRE, A CORPORATION OF MAINE.

WINDING-MACHINE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, EDWIN MOREY, a citizen of the United States, and resident of Nashua, New Hampshire, have invented an Improvement in VVinding-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to machines for winding paper in the form of tubes and for other purposes.

The character of the invention may be best understood by reference to the following description of an illustrated embodiment thereof shown in the accompanying drawings, wherein:

Figure 1 is a front elevation of an illustrative winding machine shown herein as embodying the invention; Fig. 2 is a vertical section taken on line 2-2 of Fig. 1; and

Fig. 3 is a vertical section taken on line 3'3.

of Fig. 1.

Referring to the drawing, the illustrative machine shown therein as embodying the invention comprises a frame 1 associated with a paper pulp containing vat (not shown)- containing a mold cylinder 3. Cooperating with the mold cylinder is a couch roll 5 and a web carrier 7. The above parts may be of usual well known construction and are adapted to form a web of paper from the pulp in the vat. The web of paper is conveyed by the carrier to a suction or base roll 9 of any suitable or usual construction. The web .of paper may be transferred to and wound on a tubular mandrel 11 of aluminum or other suitable material.

The mandrel shown is of small diameter and considerable length and therefore is liable to bend axially and destroy the uniformity of the winding of' the paper web thereon unless provision is made for maintaining the mandrel in straight axial alinement. To this end there is provided a presser roll 13 of substantial diameter and weight, said roll being journaled in bearings in a frame 15' on free ends of arms 17 pivoted to-brackets 19 projecting fromthe machine frame.

An important feature of the invention relates to the relation of this presser roll with the mandrel. As shown herein, the mandrel base roll is rotated in a contra-clockwise direction and the mandrel is frictionally'ro- 'tated thereby in a clockwise direction. The

presser roll is mounted to bear on the mandrel at a line offset somewhat from the left (Fig. 2) of a straight diametrical line common to and passing through the base roll and mandrel centers. Tangent lines, if

drawn through the points of contact of the mandrel with its base and presser rolls, would converge to the left of said figure. The mandrel in rotating tends to work itself toward the apex formed by said tangents and thereby tends to crowd itself in between the base and presser rolls, and prevents any bellying of the mandrel or departure thereof from straight axial alinement. The use of a single presser roll in preventing distortion of, the mandrel is extremely advantageous, since the roll contacts with the soft paper pulp being wound on the mandrel along but one line of contact, and thereby a uniform pressure is maintained bn the mandrel tending to produce a paper tube of uniform compactness and consistency throughout.

The rotating of the cylinders and rolls described will wind the paper web on the mandrel until a desired thickness of tube or material is obtained. On the occurrence of this event it is desirable to remove the mandrel from its active winding position between the base and presser rolls and to substitute an empty mandrel therefor.

An important feature of the invention relates to mechanism for shifting the manvdrels to and from actiie winding position. To this end there is provided a carrier 21 comprising spaced elongated heads 23 fast on a shaft 25 journaled in bearings in the frame 1, said heads being provided with bosses 27 in which are journaled shafts 29. Fast on these shafts. are arms 31 having suitable provision for detachably.supporting' the mandrel 11, referred to, between their 'free ends. As shown herein, the carrier is provided with two sets of diametrically opposed arms such as described for supporting two mandrels, one in active and the other in inactive position. It will be understood, however, that the carrier may be equipped to accommodate any desired number of mandrels. The carrier is rotated at appropriate intervals to withdraw one of the mandrels from active winding position and substitute an empty mandrel therefor. To this end the carrier shaft 25 is provided adjacent one end thereof with a friction disk 35 (Fig. 1) fast thereon coiiperating with a second friction disk 37 loose on a reduced portion of said shaft. The disks 35 and37 are constructed and arranged with approintimate frictional engagement.

chine frame. provided with a. large sprocket wheel 47 driven by a .sprocket chain 19 from any appropriate source of power. A

Sincethe friction disk 37 is continuously rotated it will continuously ,tend to rotate the friction disk 35 and the shaft and mandrel' carrier. The carrier must be locked against rotationwhile the mandrel isbeing wound. To this end the carrier is provided with an end plate 51 (Fig. 2) having a notch at its-lower end coiiperating with a locking lug 53 on a sliding plate 55 supported on the machine frame by pins 57 entered through elongated slots 59 in said plate. The locking plate is normally held up to present the lug 53 in locking engagement with theplatenotchby a helical spring 61 interposed between the lower end of said plate and a bracket 63 projecting laterally from the frame 1.v By moving the locking I a plate downward the lug 53 will release the pivoted on a pin 87 plate 55 referred to.

plate 51 and'the carrier will be rotated. in a contra-clockwise direction (Fig. 2) by its.

frictional driving mechanism described.

As shown herein, means is provided for automatically releasing the lock lug by the movement of the mandrel arm 31 asit is rocked upward by the increase of material' wound thereon. To this end each rocking mandrel arm is provided with a" dog 65' (Eig. 2) for engagement "with an arm 67 fulcrumed on a pin 69 carriedsbya bell crank lever 71 fulcruined on a pin 73 projecting from the frame 1'. One arm of this bell crank lever is provided with an elongated slot '75 for receiving a pin 77. projecting from the lockplatefor a purpose to bedescribed. The rocking movement of the arm 67 istransmitted by an adjusting screw 79 to a lever 81 also pivoted on the pin 69, said lever intur'n being provided with an adjust ing screw 83 for engagementwith a dog 85 projecting from the lock Continuously rotated adjacent the end of the dog 85 is an arm 89 fast on the shaft45 levers 115' fulcrumed on the shaft 45 re .ferred to. r To rock theselevers and lift the I referred to. When a predetermined amount of material has been wound uponthe active mandrel 33 its supportingarm 31 will have rocked suflicientlyto cause its dog 65 to engage the arm 67 -androck the latter, this movement being transmitted to the lever 81 throughthe screw 79. The lever 81 then rocks the dog 85 mto the range of the continuously rotated'arm 89. On the occurrence of'this event the arm 89 will. engage the dog 85 and operating through the latter, will slide the locking plate 51' downward against the resistance of its spring, thereby releasing the lug 53 from the locking plate notch and permitting the mandrel carrier to be rotated by its frictional driving means to withdraw one of the mandrels from active position and introduce another of said mandrels into active position. v

The mandrel carrying arms are free to swing on the carrier. Therefore, in the course of the rotation of the carrier in shifting the mandrels, said arms would tend to swing and depend downward. As a result, the filled mandrel might drag objectionably along the surface of the web on the roll, with liability of injuring the soft paper tube on said mandrel. It is, therefore, desirable to positively control and guide the mandrel swinging'arms in the course of the rotation of the carrier. To this end each of the -mandrel arm shafts 29 is provided with a contfollin-g arm 101"(Fig, 3) having at its free end a roller103 received in and guided by apwithdrawal cam slot 105 andan introductioncam slot 107 in a-plate 109 at one .end of the carrier and secured to' the machine frame. The entrance end of the withdrawal cam slot 105 is so formed that on the "initial rotation of the carrier the mandrel is immediately lifted up out of engagement with the base roll. The continued rotation of thecarrier will cause the mandrel to be guided thence to the position shown at the left of Fig. 3 at the front of the machine. Here the mandrel is readily accessible and may be manually removed from its arms and an empty mandrel substituted therefor. After an empty mandrel has been placed on the arms the latter are manually swung over to present the mandrel in the position shown 'in dotted lines at111 (Fig. 3)- In this position the guide rolleris at'the entrance throat of the introduction camslot 107 in readiness to be guided by the latter into-active position for winding on the next rotation of the carrier. Thus the rotation of the latter simultaneously automatically with, draws a full mandrel from active position and substitutes an empty mandrel therefor.

Before a mandrel can be shifted to and from active position the presser roll should be lifted 'out of engagement therewith. To

this end the presser roll frame 15 (Figs. 2 a

and 3) is connected by vertical rods 113 with presser roll up out of engagement with the mandrel they are extended beneath cams 11? ed fastbn a shaft 121 journaled inbearings in the machine frame and parallelin the having flat faces 119,;said cams being mount.

the shaft 45 is provided with a spur gear 123 fast thereon driving a gear 125 loose on the shaft 121. To transmit the drive from the gear 125 to the shaft 121 they are provided with cooperating friction disks 127 and 129 (Fig.1). i

,To normally lock the'sha ft 121 against rotation it is provided at one end thereof with a dog 131 (Fig. 2) engaging a lug 133 projecting laterally from the lock plate 55 referred to. When the lock plate is slid downward as described, first the lug .133 will escape beyond the end of the dog 131, thereby permitting the shaft 121 and the cams thereon to rotate, causing said cams to engage the levers 115 and j tilt them, thereby lifting the rods 113 and 'the'presser roll 13 up out of engagement with the mandrel.

Continued downward movement of the lock plate will cause the lug 53 to release mechanism to shift a filled mandrel from windin position and substitute an empty mandre therefor as described. In the course of this shifting movement the lug 53 is pressed by the spring 61 into engagement with the edge of the carrier 51 which is formed to permit the upward movement of the lock plate under the action of said spring and thereby bring the lug 53 in position to catch into a diametrically opposite notch of the" lock plate and limit the rotation of the carrier. The notches in the carrier plate thus serve to determine the active winding position of the mandrel. The carrier is held firmly against one or the other of the lugs by the tendency to drive the carrier shaft continuously through the friction disks 35 and 37 referred to.

The carrier with its swinging mandrel guided and controlled in their shifting movements by the cam slots as described.

In order to permit tubes of varying thickness to be wound the screws 79 and 83 may be adjusted to cause the mandrel. operated dog 15 to engage the arm 67 earlienor later as desired.

To prevent interference bythe arm 67 with the mandrel arm operated dog in theretreat of the mandrel from activeposition the bell crank 71 is rocked about its pin 73 as a fulcrum to move the arm 67 out of range with the dog 65, this movement being effected by the sliding of the pin 77 in the elongated slot of said bell crank when the 'lock plate is slid downward to release the locking lug 53 from the carrier plate 51. Since the carrier cannot rotate until the locking plate has been moveddown the preventing of interference with the dog 65 is assured.

burden of supporting a heavy mechanism for shifting it and enables the free swinging movement of said arms as the pulp layer accumulates thereon. 1

lBy the construction and arrangement of v the presser roll 13 the mandrel is maintained in straight axial alinement and thus is pressed equally by said presser roll throughout itslength. On the completion of the winding of the pulp on a mandrel the presser roll is automatically, mechanically lifted out of engagement with the mandrel by a simple and effective mechanism While the invention has been described herein as embodied in a paper tube winding. machine, it will'be understood that it is not limited ,thereto, but is obviously applicable to machines for other purposes.
