assignors to Beloit Iron Works, :Beloit, Wis, a corporation of Wisconsin Application November-2, 1950, Serial No. 193,585 Claims. -(Cl. 242-55) The present invention relates to' a Winder shaft puller and table and more particularly to'means for removing a wound paper roll from a windingsapparatus and for removing a winder shaft from the roll.

In the manufacture of paper,the end product is a bulky, cylindrical, tightly wound roll of paper which, in the operation of modern high speedpaper making machines, is too bulky and heavy for manual handling. Various types of roll handling equipment havebeen proposed for facilitating removal of a wound roll from a winding or rewinding apparatus, and also for'removing a winder shaft upon which the roll is formed.

The prior art handling apparatusconventionally includes a conveyor or similar means for removing the roll from the shaft by retaining the sha ft in fixed positionand moving the roll therefrom axially of-theshaft. It will be appreciated that such handling "apparatus requires a relatively heavy conveyor means for moving the-roll, as well as'requiring a large amount of floorspace to accommodate the handling equipment.

In addition, a new set of coresmust beslippedon the shaft before the shaft can be reused 'in a subsequent winding operation, andthe use 'ofprior fixed shaft-type handling apparatus required the manual'positioning of new cores upon the shaft.

The present invention now'provides"animproved paper roll handling apparatus whereinth'e shaftis axially pulled from a stationary roll by'th'e utilization of *a relatively small shaft'conveyor, rather thanpulling the'roll from the fixed shaft as heretofore proposed. Generallyjthe present invention includes a roll table Positioned immediately adjacent the roll Winding apparatus so as -to receive a wound roll therefrom. The 'rolltableincludes 'atiltable apron bridging the' gap betweenfthe winding apparatus and the table proper, and power means for tilting 'the apron to move the roll to'itsfixed position overlying'a slot formed in the table.

When the roll is positioned withinthe table slot, a shaft conveyor is moved to engage one end of the-shaft, and the conveyor is thenen'ergized'to pull the shaft from the roll. The table is also'providedwithpower means for ejecting the roll from the table slot. The power ejecting means may either take the form of a movable table portion for rolling the roll "ontoan associated Wrapping table, 'or a portion ofthe ro'lltablemaybelowered, so that the roll is deposited upon 'a'supportingfioor surface.

Following removal of thefr'ollfrom'the table, a new roll core or set of cores is positioned inthe'ro'llt able slot and the conveyor is re-energizediin the opposite direction to insert the shaft 'within'th'e core. 'Afterthe core has been position upon the shaft 'by'm'ovement'o'f the shaft into the core, the core is rem'oveilfrom'the tablefor repositioning in the windingapparatuseither by manually rolling'the core along the table and apron surface or by energization of power'means carried by thetable for'this purpose.

It will be appreciated that the apparatus of the present invention may also be used *inconnectionwith 'coreless collapsible shafts as' well as the more usual core-type winding shafts.

It is, therefore, an important object ofth'eipresent invention to provide an improvedpaper'rollhandling apparatus wherein a shaft-is removetl*fi-om'"the roll by "means of a shaft-pulling conveyor.

ice

Another object of the present invention is to provide an improved roll handling apparatus including a roll table having a slot therein forpositioning a paper roll, shaft pulling mechanism aligned with the table .slot for removing a shaft from the roll while the roll is retained upon the table, with the shaft pulling mechanism also being operable to insert the shaft within a new core positioned within the table slot.

It is a further important object of the present invention toprovidean improved paper roll handling apparatus including a roll table adapted to be positioned adjacent a roll winding mechanismfor receiving a paper roll from the winding mechanism, the table being provided with power means for positioning the roll thereon for removal of the roll shaft and for ejecting the roll from the table after the roll shaft has been removed.

Still another important object of .the present invention is to provide an improved paper roll handling mechanism in which a paper roll is positioned upon a table so that the roll shaft may-be engaged by a shaft pulling mechanism which is vertically adjustable to accommodate the removal of shafts from rolls .of varyingsize.

Yet a further important object of the present invention is to provide a winder shaft puller and table wherein a roll shaft may be removed from a roll positioned upon the table by utilization of a shaft conveyor, the shaftfree roll may be ejected from-the table, and the shaft puller mechanism utilized to reinsert the shaft within a new roll core.

An additional object of the present invention is to provide a winder shaft puller and table for paper rolls having shafts extending axially therethrough and including power means forpositioning the roll'within a table slot, means for pulling the shaft from the roll by actuation of a power operated shaft puller mechanism while retaining the roll in position within the table slot, power means for ejecting the roll from the slot, thereby removing the same from the table, means for reversing the direction of movement of theshaft puller to insert the shaft within a new roll core, and means for removing the new core from the table for a subsequent winding operation.

It is a still further object of the present invention to provide a table for receiving a wound paper roll and including means for elevating and lowering the entire table and means for tilting aportion only of the table to eject a roll therefrom.

Yet another object of this invention is to provide a shaft pulling apparatus including a shaft conveyor, means for elevating and lowering the conveyor, and means for moving the conveyor in opposite lateral directions to remove a shaft from a wound paper roll, to retain the shaft in removed position,-and to re-position the shaft for a subsequent winding operation.

Other and further important objects of this invention will become apparent from the disclosures in the specification and the accompanying drawings.

Figure 14 is a fragmentary sectional view, similar to Figure 11, illustrating lowering of the table to deposit the paper roll on a supporting surface.

As shown on the drawings:

In Figures 1 and 3, reference numeral 10 refers generally to a shaft table and puller assembly of the present invention which is particularly adapted for utilization in conjunction with a drum-type paper roll winder 11 including a pair of roll binding drums 12 rotatable about substantially horizontal parallel axes, one of the drums 12 being driven by a suitable source of power. The drums 12 cooperatively support thereon a paper roll 13 formed of successive layers of paper wound about a core C peripherally enclosing a shaft S.

The supporting structure for the lower winding drums 12 includes (Figure 3) a supporting beam 14 from which there projects an angled stop member 15 including an upwardly projecting stop arm 16. A roll table 17 is mounted adjacent the winder 11 in spaced relation to The table 17 includes a plurality of transversely spaced upstanding support brackets 18 (Figures 2 and 3) which rest upon a supporting floor F. The brackets 18 are provided at their upper forward portions with upwardly projecting extensions 19 which rotatahly journal a longitudinally extending apron axle 20.

An apron 21 is provided to bridge the gap between the table supporting pedestals 18 and the winder support beam 14, the apron being formed of a plurality of separate elongated fingers 21a. The apron 21, when in its normal lowered position (Figures 3, 4, and 5), rests at its outer end upon the upstanding stop arm 16 hereinbefore described. Each finger of the apron 21 is provided with a dependent boss 22 at its inner end for rotatably receiving the axle 29 therethrough, and the axle carries, intermediate adjacent pedestals 18, a cam 23 having an arcuate exterior camming surface 24 and pivotally connected at its free end, as at 26, to an actuating rod 27 of a pneumatic or hydraulic cylinder 28. That end of the cylinder 28 remote from the cam 23 is pivoted, as at 29, to a lower supporting bracket 30 resting upon the lower supporting floor-F.

The operation of the apron 21 will be appreciated from the foregoing description in that the paper roll 13 upon movement from the winder 11 will be initially placed upon the apron 21 when the apron is in its lowered position as seen in Figure 3. Upon actuation of the differential fluid pressure cylinder 28, the piston rod 27 of the cylinder will be extended beyond the cylinder to rotate the cam about the longitudinal axis of the axle 24) as a pivot point, with the camrning surface 24 of the cam 23 contacting the undersurface of the apron 21, thus tilting the apron about the axle 2% and causing the roll 13 to roll from the apron onto the table proper as will be hereinafter described.

That portion of the table 17 upon which the roll 13 is placed following elevation of the apron 21 is provided by a plurality of table bars 32 having horizontal upper surfaces aligned with the upper surface of the apron fingers 21a when the apron is in its horizontal position, The plurality of bars 32 are spaced along the length of the table and are supported upon the pedestals 18 by means of longitudinally extending supporting beams 33 secured, as by welding or the like, to each of the table bars 32 andto each of the pedestals 18.

Immediately rearward of the table bars 32, each of the pedestals 18 is provided with a generally V-shaped notch 34, the inclined sides of the notches having secured thereto elongated core cushioning bars 35. Immediately adjacent and above each of the cushioning bars 35, the pedestal carries I-beams 36 which project upwardly from the pedestals to carry on their upper surfaces front andrear roll beams 37 and 38, respectively. The roll beams 37 and 38 are provided with adjacent, oppositely inclined inner beveled edges 39 which cooperate to form a second larger notch directly overlying the first notch 34.

A curved roll kicker arm 42 is pivotally attached to a rearward portion of three of the pedestals 18, as at 43 (Figures 2 and 4), and the free, forwardly and upwardly extending ends of the arms 42 carry thereon the forward I-beams 36. The I-beams 36 thus merely rest upon the pedestals 18 when in their solid line positions as illustrated in Figure 4, and the forward I-beam 36 is adapted to be moved from its resting position upon the pedestals 18 when the kicker arms are actuated.

Thus, it will be seen that the forward I-beam 36 is actually carried by the roll kicker arms 42, with the weight of the I-beam 36 and the associated roll beam 37, together with the roll 13 superimposed thereon being borne by the pedestals 18 only when the roll beam is in its normal lowered position as illustrated in full lines in Figure 4. Actuation of the roll kicker arms 42 is accomplished by means of fluid pressure cylinder actuating arms 44 pivoted, as at 45, to an intermediate, forward portion of the arm 42. The actuating arms 44 are extensible beyond the associated cylinders 46 when the cylinder is energized, as by connection to a source of fluid under pressure, and the cylinder is pivoted intermediate its length, as at 47, to an upstanding support 48 carried by the floor F.

From Figure 2, it will be seen that a plurality of roll kicker arms 42 are provided along the length of the roll table, and each of these arms 42 is provided with its individual actuating cylinder, with all of the arms of these cylinders being simultaneously actuated to cause movement of the roll 13 from the roll support beams onto an additional roll support table 41 positioned immediately to the rear of the table 17.

After the paper roll has been moved onto the table 41, the shaft puller mechanism is reenergized to replace the shaft S within a new roll core C, and the roll core is then placed upon the under winding drums for the reception of a new roll of paper. If, however, a coreless collapsible shaft is used, the shaft is merely replaced upon the table 17 and then moved onto the under drums.

The mechanism particularly illustrated in Figure 3 of the drawings is utilized for this purpose, and it will be seen that there are provided a pair of core arms 50 at spaced points along. the length of the roll table. The core arms 50 are generally arcuate in shape and one end of each arm is pivotally supported, as at 51, by an upstanding arm support post 52. The other end of the arm is pivoted, as at 52a, to the actuating rod 53 of a fluid pressure cylinder 54 which is pivoted at 55 intermediate its length between a pair of upstanding cylinder support posts 56 projecting upwardly from the supporting floor F. That end ofeach arm 50 secured to the cylinder actuating arm 53 is provided with a plane core contacting surface 57 which is moved 'upwardly'upon actuation of the cylinder 54 and pivoting "movement of the arm 50 aboutits 'point 'of pivoted attachment 51 to contact the 'coreC, thereby'elevating the core to a positionupon the "roll support beam 37. The core pads '35 are cut away, as at 58- (Figure '2), to accommodate movement of the core arms 50 'therethrough. After the core has been 'pflace'd in the dotted position shown in Figure 3, it may then be readily manually rolled upon the roll'support bars 3'2, and'moved over the apron 21 to its position upon the =W'inder under drums -12.

"core supporting notches 34'onto the roll beams for later m'ovement across =the'bridging bars 32.and the apronbars .21- onto the winder under drums 12.

The above described procedure for utilization of the table :17 may be changed slightly :as desired. As particularly :illustrated in :Figure :3 Of? the drawings, it will be seen that a core and shaft, or coreless shaft, posiktionedwupon the shaft-cushioning bars 35 will 'be displaced well "below the roll 13 borne by the roll beams 37 :and'38. Thus, the following procedure "may be carried out; theshaft S and the 'corefQmay be positioned .within themotch 34 to rest upon the core-cushion bars 35, then a vroll 13 may be superimposed thereon by actuation of the apron 21 as hereinbefore explained. The shaft from the finishedroll -13 may then'be-withdrawn, the roll ejectting arms llenergized to remove the roll from the table 17,*andIfinall-y the 'core'return arms 50 energized to place the shafts of the core C upon the table bars32, as hereinbefore explained.

The shaft puller 40 is particularly illustrated .in Figures .1, 6 and 7 of the drawings. Theshaft puller is utilized only after the roll has been positioned upon the roll.beams -37 and 38 as hereinbefore described. The shafts is-normally retained .within theroll .core .by means of shaft nuts 60 threadedly retained upon the shaft to tightly clamp the core thereon. To remove the shaft, theshaftnut60 atone endof the. shaft must be removed, 'sokthat the shaft may be pulled axially of the roll and the. associated core.

Theshaft S, after the roll has been placed in position -on..t he.roll beams, is energized to pull the shaft from the roll. As best shown in Figures 6 and 7, the shaft puller includes two pairs of spaced supporting pedestals 61, eachpair of which has linner opposing vertical guideways 62 slidably journaling guide carriages 63 therein.

Each of the guide carriages 63 (Figure 7) includes upstanding spaced guide posts 64 which are slidably received by the guideways 62. The .posts 64 are joined by a lower 'frame member 65 which rotatably receives an elevator rod 67. The lower free end of the'elevator rod .67 .is threaded as at 68 and depends into a cylindrical lubrication housing 69 closed at its upper end by packing nut 70. The extreme lower end ofthe elevator. "rod '67, which is continuously threaded to its free end, extends through a gear housing 71 into a second lubricating housing72having its lower end also closed by packing nut 73. The lower threaded portion 68'of the elevator rod 67 extends below the surface of the floor F and the "housings '69 and 72 are likewise located'be'low the floor. The lower threadedportion 68 of the elevator. rod is surrounded-intermediate its length by an internally threaded gear-"nut 74 which has'its exterior periphery formed as a worm gear"75 in meshwith-a worm 76"keyed to a driven 's'haft 7-7.

=As shown in 'Fi'gure -'6, the shaft 7-7 is {connected by suitable "means, as byshaft'78, to one end of the drive shaft 79 of an electric motor '80 supported upon a pair of transverselyspaced I-be'ams -81 which also ser-ve 'to=support the gear housing 71. The other end of the drive shaft 79 is'connected in a similar manner to a second driven shaft 77 for driving a worm and worm gear arrangement within a second gear box 71 for rotating the other ofthe elevator rods -67. It will be seen that the gear box 71 prevents vertical movement of the worm gear so that driving of the worm '76 by energizatiomof the motor '80 will cause corresponding rotation of --the worm gear nut 74 to rotate the elevator shaft 67 by virtueof its threaded engagement with the worm gear nut to cause elevation and lowering of the slide carriage 63. Thus, the slide carriages 63 may be moved vertically in a path determined by the guideways -'62 formed in the upstanding pedestals '61 hereinbefore described.

'The carriages 63, or more particularly, the-uprights 64 carry at their upper portions side frame beams 83. One such side frame beam 83 is carried by one of each pair of thepedestals 61, the frames '83being securedto the pedestals by suitable means, as by bolts "84, and a pad-85 is interposed between each pedestal and the associated frame member 83. The corresponding ends of the frames -83 adjacent the table 17 journal therebetween a shaft 86 which is slidable lengthwise within a slot 86a formed in the beams to permit longitudinal adjustment of the shaft relative to the frames. The shaft 86 carries a pair of sprocket gears 87 and a clamping-plate '87a-is provided exteriorly 'of the frame for clamping the shaft and sprocket in a desired longitudinally adjusted position.

An additional pair of sprockets '88 are carried by the frames 83 adjacent the opposite ends thereof, the sprockets 88 being keyed to a shaft-89 journa'led between the frame members for rotation. The sprocket 88 is driven by means of an electric motor 90, or other suitable source of power, mounted upon a motor support bracket 91 secured tothe side frame members 83 bydependent legs 92. Themotor has a drive shaft 93 for trans mitting motive power to a worm-type speed reducer 94 having a driving worm 95 geared to the shaft 89 to drive the same. A sprocketchain 96 is trained-aboutone of each pair of the sprockets '87 and 88, and it will be seen that the driving of the sprockets 88 by energization of the motor 90 will effect travel of the sprocket chain 96.

A chain support plate 97 is secured to each of the frame members 83 to'extend inwardly therefrom 'and'along the length thereof, as best shown in Figures '6 and 9. The support plate 97 slidably receives the upper reach of the chain 96 thereon, so that sagging-of the upper reach of the chain, due to the chain weight, may be prevented. The lower return reach of the chain is supported byone or more chain idler sprockets 98 secured .to the frame members 83 and dependingtherefrom.

As best shownin Figures 6 :and 8,.the chain carries a shaft-engaging puller .100 which is secured to each of the chains 96 to extend therebetween for movement therewith. The puller 100 comprises a bottom plate 101 bridging the chains and secured thereto by suitable means,.side plates 102 joined to the bottom plate 101 and projecting vertically 'thereabove, and spaced

transverse plates

103 and 104, the forward transverseplate 104 having a-central arcuately bottomed notch 105.

Also carried by the sprocket chain 96 are a plurality of shaft ipads 106 comprising a metal block-or thelike having a depressed upper arcuate seat 107 and carrying lower angular brackets 108 attached to the inner extremities of the sprocket chains .96. Inasmuch as thejpads 106 are attached-to the inner surfaces of the chains 96, there is no-interference of the pads with either of the drive sprockets "8788 .or with the idler sprockets 98. Accordingly, the pads 106 can passaround the drive sprockets and over the idler-sprocketwithout :interfering with the chain drive. It will be appreciated that there is no possibility of any interference by the shaft puller 100, inasmuch as this member merely travels on the upper surface of the chain assembly, in other words along the length of the support beams 83, so that the puller is constantly supported thereby and does not pass about either of the

drive sprockets

87 and 88.

In use, when a roll 13 has been positioned upon a winder table 17 as hereinbefore described, the shaft puller assembly is raised from its depressed position, so that the extreme shaft flange S at the driving end of the shaft S is positioned between the

transverse plates

104 and 103 of the puller. It will be appreciated that this elevating movement is accomplished by the power means driving the elevator screws 67 to raise the guides 63 in their path determined by the pedestals 61.

Next, the motor is energized to drive the drive sprocket 88 through the speed reducer 94 and the shaft S is pulled from the roll 13 by engagement of the shaft flange S with the forward transverse plate 104 of the puller 100. During retractionof the shaft 8, the pads 106 are brought into supporting engagement with the shaft S by their travel with the sprocket chains 96, so that the shaft is supported at a plurality of points along its length, as shown in dotted outline in Figure 6.

Following retraction of the shaft S, the roll may be removed from the table 17 as hereinbefore disclosed, and the shaft puller assembly lowered by re-energization of the motor 80 to a height desirable for reinsertion of the shaft within a set of roll cores supported upon the table, or for merely placing an expansible shaft upon the table. Following vertical positioning of the shaft, the motor 90 is re-energized in an opposite direction to return the shaft to the Winder table, the shaft being moved by contact of the terminal flange S thereof with the rear transverse plate 103 of the puller 100.

In Figures 10-14, there is illustrated a second form of -winder table similar to that hereinbefore discussed in of the pit, as by means of tie bolts. The frame members also aid in supporting upstanding lift frame guide plates 126 which are secured to the sides of the pit by suitable means, as by tie bolts 127, to extend in parallel spaced relation. The guide plates 126 are provided with vertical opposed guide grooves 126a (Figure 10).

Additional lift frame guides are provided by side beams 12S carried by the longitudinal I-bearns 123 at each end thereof and secured to the pit sides by tie bolts 129. The frame guides 128 provide inner upstanding guide posts 130 which carry on their opposed facing surfaces inner grooves,

to be hereinafter more fully described, for receiving corresponding portions of a lift frame.

The longitudinally extending I-beams 123 carry thereon an electric motor or similar power means 131 having oppositely extending drive shafts 132 terminating at spaced gear boxes 133 and also at a central gear box 134. The

gear boxes

133 and 134 contain worm gear and worm drive mechanisms similar to those hereinbefore described in connection with the gear boxes 71 of Figure 6.

The gearing housed in the boxes 133' drive elevator rods 135 projecting through the gear boxes and formed with screw threads in the same manner as the elevator rods 67, also hereinbefore described. The elevator rod casings are lubricated by means of vertical lubricant lines 138.

' The upper ends of the elevator rods 135 terminate in enlarged cylindrical housings 139 which contact transversely extending lift frame beams 140 (Figure 11). .The transversely extending lift frame beams 140 are joined by longitudinally extending lift frame beams 141 to define a completed lift frame carrying thereon a roll table 142. The lift frame is driven for vertical movement by the energization of the power source 131 and elevating or lowering movement of the elevator rods 135, this vertical movement being guided by a transversely extending frame glide 143, the edge portions 144 of which are received by the central guide slot 126a formed in the frame guide members 126 which are carried by the upstanding support posts 124. The lift frame is also guided against transverse movement by oppositely directed side guide members 145 having oppositely directed edge portions received by similar slots formedin the guide members 130;

Thus, the lift frame is guided against transverse and longitudinal movement during elevating and lowering of the same, and power means are provided for effecting such vertical movement.

The longitudinal guide frame beams 141 carry a plurality of transversely extending table pedestals quite similar to the pedestals 18 of the earlier described roll table 17. The pedestals 150 are each provided with an upwardly projecting forward extension 151, each receiving therethrough an apron shaft 152. The apron shaft has secured thereto for rotation therewith a plurality of apron fingers 153 cooperating to define an apron 154 for serving the same function as the apron 21 previously described. Each of the apron fingers 153 carries a dependent embossment 155 (Figure 12) receiving the shaft 152 therethrough and secured to the shaft. The shaft 152 is provided. with a pair of spaced squared shoulder portions which are engaged by correspondingly shaped surfaces 156 formed by a rocker arm 157 secured to the shaft pivotally carried at its free end, as at 158, by an actuating rod 159 of a fluid pressure actuated cylinder 160. The cylinder 160, of course, is provided with an interior piston movable therein under differential fluid pressures to extend the actuating arm 159 to its position shown in dotted outline, thereby turning the shaft 152 to tilt the apron 154 to a substantially vertical position shown in dotted outline in Figure 12. The cylinders 160 are pivotally attached to an adjacent pedestal 150 by suitable means, such as a pivot plate 161 welded or otherwise attached to the pedestal 150 and carrying a pivot pin 162.

Immediately to the rear of the apron 154, the pedestal carries a pair of upstanding channel irons 163 bearing on their upper surfaces a plurality of table bars 164 in horizontal alignment with the apron fingers 153. .The table bars 164 are adapted to receive a roll placed upon the fingers 154 and moved therefrom as the apron is elevated, in much the same manner as hereinbefore described.

Each pedestal immediately to the rear of the table bars 164 carries a table pivot pin 165 passing through an embossment 166 formed on each pedestal and received by corresponding depending embossment 167 formed on a tiltable table portion indicated generally at 170. The tiltable table portion 170 is thus mounted for pivoting movement about the pivot pins 165 relative to each of the pedestals.

The table portion 17 0 is defined by a pair of .long'itudinally extending transversely spaced channel irons 171 joined by upper and lower transversely extending

irons

172 and 173, respectively, the lower transverse iron 173 cartying the embossments 167 and the upper transverse iron 172 having a notch formed therein intermediate its length by a pair of inclined side irons 174 and a bottom iron 175.

The lower table iron 173 carries adjacent its rear end a plurality of additional depending pivot bosses 176.. The dependent bosses 176 are each joined by a pivot pin 177 to an upper link arm 178 which in turn is joined by a pivot pin 179 toa lower pivot link 180 which is pivoted, as at 181, to the rear I-beam 141. The pivot linkage formed by the links 178 and 180 is adapted to be broken by an actuator arm 182 secured thereto and forming a part of a fluid pressure actuated cylinder 183 of conventional type having a piston connected to the arm 182 and reciprocal within the cylinder 183. Each cylinder 183 is pivoted to a supporting plate 184 carried by the associated pedestal 150 It'will be seen that upon actuation of the cylinder 183, the rod 182 will be withdrawn into the cylinder to break the linkage formed by the links 178 and 180, thereby pivoting the rear table portion 170 about the pivot pins 165 joining the rear table portion to the pedestals.

The table 142 is also provided with power actuated stop means as best illustrated in Figure 13. The stop means of Figure 13 comprises a stop plate 187 pivoted, as at 188, to the rear table portion 170 and pivoted at 189 to an upper link arm 190. The upper link arm is pivoted, as at 190, to a lower link arm 191 which is attached at 192 to the rear I-beam 141 for pivoted movement relative thereto. Here, again, the linkage formed by the

arms

189 and 191 is adapted to be broken by actuating rod 193 for a fluid pressure actuated cylinder 194 equipped with a conventional piston (not shown) for moving the arm 193 and pivotally attached, as at 195, to a bracket 196 carried by the forward I-beam 141.

It will be appreciated that actuation of the cylinder 194 to move the rod 193 rearwardly will break the linkage formed by the

link arms

189 and 191 to pivot the stop plate 187 relative to the rear table portion 170. The stop plate 187 is provided with a laterally extending stop bar 197 for preventing accidental displacement of a wound roll of paper 13 from its position upon the rear portion 170.

The operation of that form of the table illustrated in Figures 10-14 will be readily apparent from the foregoing description inasmuch as a Wound roll of paper placed upon the apron 153 may be readily moved to the notch defined by the plates 174 and 175 by actuation of the apron cylinder 160 to elevate the apron causing rolling of the tightly wound paper roll over the table bars 164 to the notch.

After the roll has been positioned within the notch, removal of the shaft from the roll may be accomplished by means of a shaft puller, such as the shaft puller 40 hereinbefore described in detail. Following removal of the shaft, the roll may be readily moved from its position upon the table by tilting movement of the rear table portion 170. This tilting movement is preferably combined with vertical movement of the entire table so that the roll may be gently deposited upon the floor surface without possibility of injury to the roll.

More specifically, the table is lowered by actuation of the motor 131, as hereinbefore explained, and the table is tilted by breaking of the linkage formed by the arms 178 and 180 by actuation of the cylinder 183, all as best shown in Figure 14.

During positioning of the roll upon the table, the stop plate 187 is maintained in its raised position, as indicated in Figure 13, so that the roll may be maintained upon the table. However, when the table is tilted to the position shown in Figure 14, the stop plate 187 is lowered by actuation of the cylinder 194, so as not to interfere with removal of the roll.

It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention.

We claim as our invention:

1. A shaft puller and table comprising a table for receiving a body having an axial shaft therethrough and said table having a positioning recess for retaining said body in predetermined position thereon, a shaft pulling conveyor movable both vertically and longitudinally with respect to said body on said table in alignment with the axis of said body when seated in said recess, means on said conveyor engaging the shaft to remove the same upon 10 movement of said conveying means longitudinally away from said table and for repositioning said shaft in said recess on said table upon movement of the conveying means in an opposite direction, and means for removing said body from said table after said shaft has been removed.

2. In a shaft puller and table, a table for receiving a cylindrical body, comprising a plurality of transversely extending, longitudinally spaced pedestals, longitudinally extending transversely spaced beams for supporting said body therebetween, said beams normally being supported by said pedestals, a body kicker arm abutting one of said beams and pivotally attached to one of said pedestals, and power means for actuating said body kicker arm to move said one beam in an arcuate path about the point of pivotal attachment of said arm, thereby removing said body from its position upon said beam.

3. In a shaft puller and table, a plurality of transversely extending, longitudinally aligned table pedestals, a pair of parallel longitudinally extending beams cooperating to receive therebetween a body, said beams being normally supported by said pedestals, an elongated kicker arm pivoted to one of said pedestals at one end and at its free end carrying one of said beams, and a fluid pressureactuated motor having a movable element pivotally connected to said kicker arm adjacent the beam carried thereby, whereby actuation of said cylinder and consequent movement of said kicker arm removes said body from its position on said beams.

4. In a shaft puller and table, a table supporting structure, a pair of beams carried by said supporting structure and extending thereabove to define a body-receiving notch above said supporting structure, means carried by said supporting structure defining a shaft-receiving notch underlying and aligned with the body-receiving notch, means for elevating one of said beams to remove a body from said body-receiving notch, and an actuating arm underlying said shaft-notch for elevating a shaft therefrom onto one of said beams.

5. In a shaft puller and table, a table adapted to receive a body comprising a plurality of transversely extending longitudinally aligned pedestals, a tiltable gate pivotally carried by said pedestals and movable relative thereto to position a body on said table, a pair of beams carried by said pedestals and spaced apart in parallel relation adjacent the other end of said table, a body kicker arm pivotally attached to one of said pedestals and movable to elevate one of said beams from said pedestals to remove said body therefrom, and a shaft kicker arm underlying said beams and pivoted at one end for movement toward said gate to elevate a shaft onto the movable one of said beams.
