The invention will hereinafter be specifically described in eonnectionwith the stripping of paper rolls from a Winder shaft and feeding the s claims. .(cl. 24g-s1) leading paper roll as it is deposited on the platform of the apparatus.

FigureI 3 is 9,4 transverse cross-sectional view, with parts in end elevation, taken along the line III-III of Figure 2.

Figure 4 is a View similar to Figure 3 but illustratin'g the platform in lowered and tilted position for delivery of the rolls of paper at a desired level.

Figure 5 is a fragmentary diagrammatic view illustrating, in vertical cross section, themanner in which the apparatus of this invention operates to completely sever adjoining rolls in the event rolls onto a receiving platform, but it should be understood that the invention is not limited to this use, being generally applicable to the un loading of rolls or the like.

The apparatus of the invention facilitates the handling of wound paper rolls, and is so arranged that the very act of delivering the rolls insures separation of the rolls fromeach other.

It is, then, an object of this inventionv to provide apparatus for unloading rolls to automatically insure separation of the rolls from each other. f

Another object of the invention is to provide an apparatus for stripping wound rolls from a shaft while separating the rolls and delivering the separated rolls at a desired level.

A still further object of the invention is to provide apparatus for unloading a plurality of Wound rolls of paper from a single Winder shaft in such a manner as to completely separate the rolls from the shaft and from each other.

A specific object of the invention is to provide apparatus for stripping rolls of paper from Winder shafts by depositing the wound rolls onto a driven conveyor, discharging the rolls olf of .one end of the conveyor While holding the shaft against movement with the rolls, and causing the leading roll to be cocked or tilted relative to the next adjacent roll. l

Other and further objects of the invention will be apparent to those skilled in the art from the following 'detailed description of the annexed sheets of drawings, which, by way of a preferred example only, illustrate one form of the invention.

On the drawings:

Figure 1 is a broken fragmentary side elevational view, with parts in vertical cross section, of a roll unloading apparatus according to this invention.

Figure 2 is a view similar to Figure 1 on a larger scale illustrating the tilting or cooking of the that the cores of the rolls are not completely severed. As shown on the drawings: 1

In Figures 1 and 2 the reference character F 'I designates a concrete floor on which part of the apparatus of this invention is mounted, while the reference character F designates a floor or supports at a lower level than the floor F. An opening O is provided in the iloor F above the Hoor F.

A conveyor I0 is mounted on the floor F with the discharge end-adjacent the opening 0. The conveyor IIJ includes a frame II carried by the oor F, sprockets I2, I2 rotatably supported by the frame I I, and a conveyor band I3'trained between the sprockets I2 and carrying flights I4. A motor I5 drives one of the sprockets I2 to propel the conveyor band I3. Pushers I6 are carried by some of the nights I4 to engage the end of a roll of paper lit` on Winder shaft S. The roll R is deposited onto the upper run of the conveyor band I3 from a paper rewinder apparatus (not shown) and contains a plurality of roll segments R' cut, as shown at I'I, from a single wide web of paper byv the rewinder apparatus. Since the cut I'I may not be complete, especially in the first few turns of paper on the shaft S, or in the core on which the roll is Wound, the present invention provides for complete severing of the roll segments R from. each other.

A shaft holding device 20 is mounted on the floor F at the end of the conveyor IU that is remote from the opening O. This holder 20 includes a Vertical frame 2| providing a way 22 on which a carriage 23 is mounted. A motor 24 drives a shaft 25 to raise and lower the carriage 23 on the way 22. The carriage 23 carries a gripper 26 for engaging one end of the Winder shaft S. .A The carriage positions the gripper so that it will be A level With the shaft,

The motor I5l actuates the conveyor band I3 to bring a pusher vIii-into engagement with the lend of the roll R as shown in Figure 1. The pusher and conveyor then move the roll R relative to the shaft B which 'is held stationary by the gripper 2l to successively strip the roll segments R' oif of the reduced diameter end S' of' the shaft as shown in Figure 2.

A platform Il is provided adjacent the discharge end of the conveyor Il to receive the roll segments R from the conveyor. This platform ll includes a plurality of transverse rollers Il at spaced intervals along the length thereof supported by a frame I2 composed of longitudinal and cross beams. One side of the frame 32 has depending lugs 3l at intervals along the length thereof pivoted to supports I4 adjacent one end of each support. 'I'he other side of the frame l2 rests on top of the supports ll as best shownfin Figure 3. The frame 82 is thus tiltably mounted on the supports Il.

The supports 34 are carried by an elevator Il having depending brackets at the ends thereof riding in grooves of tracks Il carried by a subframe Il on the floor F'. The floor F also carries s tracks I8, as bast shown in Figures 3 and 4, for guiding brackets Il of the elevator I5. As ind cated in Figure 2, these tracks 3l and brackets 4 are midway between the tracks Il and brackets Stops 4| are carried by the tracks 31 beyond the ends of the elevator I5. These stops li have vertically adjustable heads lla for engagingl the ends of the frame 32 on the side thereof remote from the pivot brackets I3 when the elevator 35 is `in lowered position as shown in Figure 4 for tilting the platform 3l to discharge the roll segments R' offsof the rollers Il as will be more fully hereinafter described.

The elevator 3! is raised and lowered by means of screwrods l2 which extend into gear boxes I3 having` gears actuated by shafts u which are driven by a motor carried on the sub-(frame Il. The screw rods 42 have stops 46 thereon limiting the top position for the platform lli to a level slightly below the upper run'of the conveyore I0, so that the leading roll segment R will tilt downwardly onto the rollers Il` as it leaves the conveyor. l sirabie to open up the cut I1 between the roll segments R' and actually break the rolls apart by tearing the partially severed core "or first few turns of paper as indicated at-I'Ia` in Figure 5.V

Thus, as shown in Figure 5, a tubular 'core C `-of cardboard or the like is not completely severed along the cat i1 but is uncut at llc. As the leading roll R. tiltsorcocks relative to its adjacent roll, this unseveredportion l'lb will bebroken to completely severv thev roll segments into inde-` pendent rolls. This action takes place automatically as-the conveyor Il delivers theroll i segmentsfR onto the platform and oil of the This tilting actiony is yhighly destops 4| then engage the frame I! to tilt the platform Il and discharge the roll segments R' onto the iioor F. The tilting movement is sufncient to raise one end of the rollers materially above the other end so that the roll segments R will automatically roll by gravity onto the iioor F.

From the above descriptionsit will be understood that` the apparatus of this invention includes a conveyor for receiving wound paper rolls from a rewinder apparatus, a hold for gripping one end ofthe shaft on which the paper rolls are wound, and an elevator including a tiltable platform for receiving the stripped rolls from the conveyor. The elevator operates in a pit alongside of the discharge end of `the conveyor and carries a tiltable platform to a top level which is lower than the conveyor level. so that the very act of discharging a roll segment onto the platform will cause the tilting or cooking oi' this roll segment to insure complete separation of the segment from its next adjacent segment in the event that the cut between the segments is not complete.

It will, of.course, vbe understood that various details of. construction may be varied through a wide range without departing from the principles of this invention `as it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.

We claim as our invention:

i. An apparatus for handling wound adjacent rolls in severed end to end relation which comprises a stripping part and a receiving part. said stripping part arranged for discharging rolls endwise onto the receiving part, and said receiving part being at a level lower than the stripping part for cooking the leading rolls relative to the rolls on the stripping part for completely severing the leading rolls from the trailing rolls.
