摘要:
In an apparatus for handling rolls of web material, a shaft bearing one or more fully wound rolls of web material thereon are supported from one end in a cantilever support. An external mandrel is aligned with a free end of the shaft. A roll-moving device is positioned to shift the rolls axially along the shaft away from the supported end of the shaft. The roll-moving device shifts the rolls of web material off the shaft and onto the aligned external mandrel, shaft or other support device. The weight of the roll of web material is borne by the shaft and external mandrel throughout the transfer. Once the shaft is removed, the rolls of web material can be handled during further processing from the core.

A sheet roll forming system for forming sheet rolls by winding a heat transfer recording sheet around an outer periphery of a plurality of cores including a core supplying apparatus and a sheet roll discharge apparatus. The core supplying apparatus includes a cantilever shaft supporting the cores, a tray below the shaft and movable up and down in a direction of the shaft, and core stoppers on the tray where the shaft is an air shaft that can increase in diameter when air is supplied from a charge and exhaust apparatus. The sheet roll discharge apparatus includes the shaft supporting rolls of the recording sheet on the cores, a tray below the shaft, and a stopper on the tray.

A system for forming coreless paper rolls having a center aperture of a predetermined cross-sectional configuration. The coreless paper roll is initially formed by winding a web about a first mandrel element having a first cross-sectional configuration and a distal end differing from the predetermined cross-sectional configuration. After the roll is formed it is slid over a second mandrel element having an outer surface with a second cross-sectional configuration to change the shape of the coreless paper roll center aperture from the first cross-sectional configuration to the predetermined cross-sectional configuration.

A reel hub (5), an inside rod (70) of which can slide axially when acted upon by a seizing rod (82), forms part of the transfer apparatus (3). By bringing the transfer apparatus opposite the hub of a rotating reel (21, 20), and by withdrawing the inside rod from the hub, the hub is disengaged from a machine (1), the reel continuing to rotate with its hub fixed to the transfer apparatus. This apparatus can then be moved in directions situated in the plane of rotation of the reel and brought opposite another shaft of the machine in order to reattach the hub there by reversing the foregoing procedure. A rotating reel, especially one paying out a strip of cigarette paper, can thus be moved without subjecting the strip of paper to any torsion. Other operations relating to the automatic operation of the machine are also possible with the aid of the transfer apparatus.

In a rolled object holdiing apparatus whose holding members hold both ends of a roll core, a roll core releasing device comprises a core pushing mechanism which in turn consists of a core pushing member and a driving means for moving the core pushing member at least in the direction of radius of the core. The core pushing mechanism is either installed in a core receiving member or in a core holding member. Whether to operate the driving means for the core pushing member is controlled by a core detector in the core receiving member. With this construction, the core releasing device of the invention performs automatic and reliable releasing of the core from holding members of the rolled object holding apparatus, thus eliminating various problems experienced with conventional devices during automatic replacement of rolled objects.

Apparatus for automatically transferring successive fresh bobbins from a magazine wherein the bobbins are stacked in horizontal planes to one of two reciprocable horizontal spindles which are carried by a pivotable holder has annular tongs with claws which are movable into engagement with the periphery of the topmost bobbin in the magazine, and a crank drive which changes the orientation of tongs during transport between the magazine and an unoccupied spindle so that a fresh bobbin which is engaged by the claws in the magazine is moved from its horizontal plane into a vertical plane and its core can receive the unoccupied spindle.

A shaft releasably supports a plurality of separately rotatable winding reels held in place by clamps. Each reel is mounted on a sleeve assembly including an axially slidable portion, spring biased in one direction, normally holding the clamps engaged with the reels. When one of the portions is forcibly moved axially to release its clamp, it engages and moves the slidable portion of the next adjacent sleeve assembly so that all reels may be released simultaneously.

A detacher for detaching from a roll a spool supporting the roll, and the detacher includes a detacher body; and a plurality of hooking parts disposed on a circumference of the detacher body to engage a plurality of projections of a flange disposed at an end of the spool. With the hooking parts engaging the projections of the flange, the roll and the detacher are relatively displaced so that the spool is detached from the roll.
