' 13 Claims. ((1242-65) a This invention relates to paper reeling apparatus and has particular reference to apparatus for winding a web of paper in predetermined lengths on suitable spools.

g The main objects of the invention are to provide means for automatically transferring the web from a full roll to an empty spool; to provide means controlled by the spool and by the length of paper web wound on the roll for effecting operation of the automatic spool-changing mechanism; to provide such automatic mechanism which will operate efficiently and smoothly without jars or shocks; and, in general, it is the object of this invention to provide improved paper it reeling apparatus.

Other objects and advantages of this invention will be understood by reference to the following specification and accompanying drawings (four sheets) wherein there is illustrated a paper reeling apparatus embodying a selected form of the invention.

In the drawings- Fig. l is a plan. Fig. 2 is a section on the line 22 of Fig. 1. M Fig. 3 is a view similar to Fig. 2 but showing certain parts in a changed position.

Fig. 4 is a schematic illustration including wiring diagram.

Fig. 5 is a section on the line 5-5 of Fig. 2; and till Fig. 6 is a detail illustration of certain pneumatic mechanism.

Referring now to the drawings, the apparatus illustrated includes a main drum Ill which is journaled in suitable end frames such asv indicated at ht: ii. The drum I may be driven from any suitable source of power, for example, by means of a power-driven belt I? which extends around a pulley it carried by the drum shaft.

A paper feed belt it extends around a suitable roller it carried by a support it, under the drum iii, over a roller ll journaled in suitable brackets such as l8 which are carried by the end frames paper machine, calendering. rolls or other apparatus, and to deliver such web to the drum iii. For maintaining the belt it in properly adjusted relation to the drum ill, the roll i9 is journaled in brackets such as 2| which are suspended on pivots 50 such as 22 carried by brackets 28. The brackets 23 are mounted on end frame members 24. The arm M is yieldingly urged to swing away from the drum it by means of a weight 25 which is connected to the arm 2 I through the agency of a suit- 55 able cable 2t. The cable 26 extends around a roller 21 which is rotatably supported in a suitable bracket. The roller 20 may also conveniently be rotatahly mounted'in brackets 28 which may be adjustably mounted in any suitable manner to facilitate horizontal or other adjustment of 5 the roller.

Empty spools on which the web of paper is to be wound are delivered to the apparatus on tracks 29 which may conveniently be in the form of channel iron members suitably mounted on supl0 porting frame members 38. In Figs. 2 and 5, an empty spool is illustrated on the delivery end of the track 29 and is designated S. For preventing the empty spool S from rolling off the end of the track, an arm 39 provided with an upstanding portion 32, is pivoted on the inside of the track as indicated at 33. The arm M is normally urged to swing upwardly so as to maintain the projecting portion 32 in the path of the spool shaft, by means of a weighted arm at. Of course it will be understood that tracks like 29 are provided for each end of the empty spools and that each track end is provided with the described spool-retaining arm arrangement. At the free end of the arm ii there is provided an extension 35 which is adapted to be engaged by an arm presently to be described,

7 for swinging the latch arm 3! downwardly to permit the roll S to roll ofl the end of thetrack to such arm. The tracks 29 are preferably inclined at a slight angle which is suiiicient to cause the rolls to normally roll toward the delivery end of the track and off the track when the latch ii is disengaged.

Arms such as indicated at 36 are pivoted as at $1 on the inside oi the respective end frames Ii and these arms are adapted to carry an empty spool received from the tracks 29, to operative position relative to the drum (shown in Fig. 2) in which the paper web may be wound on the spool. The arms 36 are provided at their free ends with 0 spool-receiving seats 38 and the end portions 39 of these arms serve to engage the extended ends of the latch arms 3i to disengage the same as previously explained. The position of the arm 36 lllustrated in Fig. 3 is the lowered or spool-receiving position and the latch at is there shown in its disengaged position. By comparison of Figs. 2 and 3, it will be understood that the arms 36 are adapted to be swung upwardly on their pivots 31 to carry the empty spool received by the arms into said operative position.

For actuating the arms 36 and other parts which will presently be described, there is provided a pneumatic cylinder ill having a piston 4i and piston rod 42' adapted to be reciprocated in accordance with the admission of compressed air into one end of the cylinder and release of air from the other end. The piston rod 42 is provided at its free end with a rack bar 43, which is suitably supported for reciprocation on a roller bearing 44. The rack bar meshes with a gear 45, which is secured to a shaft 45. the latter being journaled in suitable bearing stands such as 41 and 41 (see Figs. 2 and The shaft 45 also carries gears such as 43 located adjacent the outsidelof the respective supporting frame members 24.-' The gears 45 and 49 are of like construction and in Fig. 2 are concentrically disposed and hence the gear 45 is directly in back of the gear 48. The gears 45 mesh respectively with gear segments such as 49 which are pivotally mounted as indicated at 50, on respective side frame members 24. It will be evident that by reciprocating the rack 43, the gear segment 49 will be oscillated. Extending from the hub of the gear segment 49 is an arm 5| to the free end of which there is pivotally connected one end of a link 52. The lower or opposite end of the link 52 is provided with an elongated slot 53 which receives a pin 54 pro-- nected to the arm 36.

When the rack bar 43 is moved outwardly, i. e., to the right in Fig. 2, the gear segment 49 will be turned in a clockwise direction with the result that the arm 36 will be lowered. It will be evident that the weight of the arm 36 causesthe same to swing downwardly when permitted to do so by downward movement of the link52. It will also be evident that when the rack bar 43 is moved toward the left in Fig. 2, the segment gear 49 will be turned in a counter-clockwise direction, thereby moving the link 52 upwardly. Initial upward movement of the link 52 will not actuate the arm 35 inasmuch as the slot 53 provides for lost motion in the connection between the link 52 and arm 55. However, when the lower end of the slot 53 engages the pin 54, upward swinging movement of the arm 35 will be effected.

The hub of the segment gear 49 is extended inwardly as indicated in Fig. 5 and at its inner end it is provided with an arm 56. The free end of the arm 56 is bifurcated as clearly shown in Fig. 5 and a member 51 is pivoted in said bifurcations. The member 51 is provided with a tail piece 58 having its end arranged to engage an adjustable stop screw 59 carried by a lug formed integral with the arm 55. The member 51 is thus permitted to swingin one direction on its pivotal connection with the arm 55, but-limited in swinging in the opposite direction by the stop screw 59. The purpose of this construction will appear in the description of the operation of the mechanism hereinafter given.

For receiving full spools, there are provided tracks such as indicated at 65, these tracks being in vertical alignment with the tracks 29 and the brake shoe and slidable through the free end of the bracket 5|.

For initially receiving a spool from the arm 35 after paper is wound on the spool and for conveying the full spool to the tracks 50, track ex- 5 tensions 55 are provided. The track extensions 55 are preferably of humped formation as best shown in Figs. 2 and 3 and these extensions may be supported by suitable connections to the tracks 50 and to the respective frame memhere 24.

For facilitating the automatic transfer of the paper web from a full spool to an empty spool, air showers are provided. One such shower is indicated at 56 and consists merely of a suitable pipe provided with air jets 51, the pipe being supported in suitable brackets 53 carried by the frame members 30. Another air shower is indicated at 69 and consists of a similar pipe carried by arms such as I0 which extend upwardly from the links 52. The source of compressed air for the shower pipes 66 and 59 may be any convenient source and in this instance the respective shower pipes may be connected to the air supply for the pneumatic cylinder 40.

In Fig. 6, the control of air supply for the pneumatic cylinder is shown as including a pair of electrically operated valves II and 12. The valve 'H is of a more or less standard type of solenoid controlled valve so arranged that when the current is turned on the valve II will be opened so as to permit compressed air to enter the left hand end of the cylinder. The valve 12 which is a similar but inverted type of solenoid controlled valve is so arranged that when the current is on, the right hand end of the cylinder is opened to the atmosphere to relieve or exhaust the air from the portion of the cylinder. to the right of the piston. The valves H and 12 are furthermore so arranged that when the current is off, the valve II will open the left hand end of the cylinder to the atmosphere and the valve 12 will admit compressed air to the right hand end.

The electrical control of the valves H and I2 may be arranged for manual operation but it is preferably arranged so as to be both manually and automatically operable.

One switch for controlling the valves II and 12 is designated A, this switch being suitably mounted adjacent the end of the track extension as clearly shown in Fig. 3. The switch A is a normally closed switch and is adapted to be opened by engagement of a portion of the spool shaft with the switch lever II. The switch A is so ar- 5 ranged that when an empty spool is delivered to operative position relative to the drum It, the switch A is opened to break the circuit controlling the valves H and 12. The arrangement is also such that the switch A is held open by the empty spool shaft until such time as the roll of paper on the spool shaft has reached such a side that the roll will be transferred from the end of the arm 35 to the track 55. When such transfer switch B is illustrated in Figs. 1 and 5. By

reference to the said figures, it will be seen that rotate one revolution to any number between approximately 220 and 650 revolutions of the shaft 16. Depending upon the setting of the variable speed unit M, the shaft may be caused to rotate one revolution for any length of' paper between approximately 2,000 and 6,000 feet. The high speed shaft it of the variable speed unit is provided with a large sprocket wheel 11 which is connected by means of a suitable chain indicated at 78 to a very small sprocket wheel 19 carried by the free end of the shaft of the drum l0.

The slow speed shaft lb of the variable speed unit it is connected to a shaft 80 through the agency of a suitable magnetic or other clutch 8i so that the connection between the shaft 80 and shaft may be broken to permit manual adjustment of the shaft 80 and parts carried thereby.- The shaft 00 is rotatably mounted in suitable bearing members 02 and 83. which are supported on a base 86. A spring pressed drag element at is arranged to bear on the shaft d0 to prevent too free rotation thereof.

As clearly shown in Fig. 5, the switch B is mounted on the base at and it is controlled by a cam roller 06 mounted on a disc M which is in turn secured to the shaft 80. The arrangement is such that when the disc 3? has made one complete revolution, the cam roller 8t will engage the free end of the switch arm st to throw the switch. The switch B is also a normally closed switch, which is opened and, therefore, breaks the elec tric circuit controlling the valves ii and 52 when the measured ount of paper has been wound on the spool.

The operation of the mechanism may be described as follows. I

As shown in Fig. 3, a roll of paper has been built up to include the desired number of feet and it may be assumed that the measuring apparatus, best shown-in Fig. 5, will now actuate the switch B to open the circuit controlling the valves ii and it. When the electric circuit is thus broken, the valves ii and it will be so adjusted that compressed air will be delivered into the right hand end of the pneumatic cylinder 50 to thereby move the rack bar 03 to the left. Such movement of the rack bar, transmitted through the gears 0t and segments tit, causes the arm 69 and part bl to swing in a counter-clockwise direction so that the part 51 engages the spool shaft and propels the full roll upwardly over the humps of thetrack extensions 65, whereupon the full roll rolls down the inclined portions of said extensions and comes to rest as an incident to engagement of the brake shoes fit on the brake During theinitial portion of the counter-clockwise movement of the arms 5%, the links 52 are pulled upwardly, but because of the pin and slot connection with the arm 55, no movement is tmitted to the arm 36. During the time of the lost motionbetween the link 52 and arm 55, the full roll of paper is being moved away from operative position-relative to the drum l0 so as to permit anempty spool .to be delivered to such position. When the lower end of the slot 53 engages'the pin 54, continued upward movement of the link 52 will of course causethe arm 36 to be swung in a clockwise direction so as to theref by carry an empty spool S into paper-receiving position, as illustrated in Fig. 2. 5

By reference to Fig. 2, it will be seen that the paper-web will then extend over and around the empty spool S and through a loop formation designated L, and thence to the full roll P It will be understood that the loop L will be formed be- 10 cause of the fact that the paper web P is continuously fed to the drum it! while the rotation of the full roll P is stopped by the described brake arrangement. The air showers 60 and 09 assist in forming the loop L by blowing the paper web 15 in the proper direction. The lower shower 6? also serves to direct the paper loop into engagement with the web of paper coming upon the drum l0 so that the loop is thereby carried into the nip between the empty spool S and the drum 20 to thereby attach the paper web to the empty spool. When the paper web is' of a thin and light character such as a flimsy crepe or tissue paper, the portion of the web between the empty spool and the full roll will be'readily broken so as to as separate the web from the full roll and to permit continued winding of the web on the empty spool. In the case of heavier paper, various well known arrangements for severing or breaking the web may be utilized. mechanism is illustrated as arranged for handling thin crepe paper which maybe readily broken and hence no severing mechanism is illustrated.

Various other arrangements for directing the web of paper into winding engagement with the 35 empty spool S may obviously be used instead of the air showers described and, in fact, the mechanism has been successfully operated without any air shower or similar mechanism. The air for the showers t6 and 6.9 may be controlled by the 40 valves ii and it or itmay be independently controlled as desired.

When an empty spool S is raised to the operative position illustrated in Fig. 2, the switch A is opened. Inasmuch as the switch B is already 4 open, the opening of the switch A has no immediate efi'ect on the electric circuit or on the valves ill and i2. l-Iowever, the disc ti is continuously driven by reason of its connection to the drum and hence the cam roller 8% will soon release the switch arm 00 and permit the same to again close the circuit. Hence when the switch B closes the circuit, the circuit nevertheless remains broken by the switch A until such time as the empty spool is filled to such a point that it is transferred from 55 the arm 36 to the track extension 65. When such transfer takes place, the switch A will again be closed, whereupon the circuit is again completed and the valves ii and it so adjusted that the air pressure is turned to the left end of the cylinder W to thereby cause the rack it to move outwardly or to the right, with the result that the arm 36 is again lowered to the position illustrated in Fig. 3. The arm 56 is also returned from its advanced position as shown in Fig. 2,'to its starting position as shown in Fig. 3. In such rearward movement of the arm 50, the back edge of the end members 01 engage the spool shaft and swing on their respective pivots so as to pass the spool shaft without pressing the partially completed roll of paper against the drum it] When the part "i clears the spool, a suitable spring arrangement associated with the pivot pin or otherwise (not shown) serves to restore the part to its operative position as shown in Fig. 3. it

In the present instance, the 30 By reference to the wiring diagram shown in Fig. 4, it will be noted that switches C and D are also incorporated in the electric circuit. The switch C is a normally closed switch and is provided for the purpose of permitting manual control in place of the paper-measuring switch B so that the winding of the paper web on one roll may be terminated at any desired time and a new roll started. The switch D is a normally open switch and is so arranged that by closing the circuit therewith, the arms 36 may be lowered independently of the action of the spool on the switch A. In other words, while a spool is in operative position holding the switch A open, the switch D may be manually closed to cause the arms 38 to be lowered.

By the described arrangement of automatic switches and electrically controlled valves H and 12, the operation of the paper reeling mechanism may be completely automatic. It being only necessary for an attendant to supply the apparatus with empty spools and to release the full rolls from the brake devices.
