  • ABSTRACT I970 Germany 2042752 This invention relates to a storage device for rolls of reproduction material of different widths comprising 2? 242/55; 226/ 242/586 at least three supply rolls with two of said rolls being [58] Flt. B65h 19/12 narrower than the third means mounting Said nan 5 3 Search "I 242/55 rower rolls with their axes substantially in alignment 312/39 226/ 10 with each other. and means mounting the third and l References Cited widest roll parallel to the two narrower rolls.
  • Reproduction material may be stored in a copying apparatus either in the form of pre-cut sheets, or as a supply roll.
  • a copying apparatus When an accurate size of the copies is essential, the first version is normally preferred. In most cases, however, this degree of accuracy is not required. In these cases, and when originals of unusual size are to be copied, it is much more advantageous to use supply rolls. Accordingly, practically used modern photoprinting apparatuses frequently use the reproduction material in the form of an endless web which is wound upon a supply roll and severed by a cutting device in accordance with the length of the original.
  • the present invention provides a compact storage device accommodating three supply rolls of different widths with large diameters.
  • the present invention provides a storage device for rolls of reproduction material of different widths, which device is part of an automatic copying apparatus and contains three supply rolls of large diameter, of which the two narrower rolls are arranged with their axes substantially in alignment with each other, whereas the third and widest roll is mounted to parallel to the two narrower rolls.
  • the device according to the invention is part of an automatic copying apparatus, in particular a photoprinting apparatus.
  • the device may be used in electrophotographic or thermographic copying apparatuses.
  • the reproduction material e.g. photoprinting paper
  • the reproduction material is withdrawn from one of the rolls and fed by means of a conveyor system to a cutting station where the paper is cut to the desired length and then combined with the original at the entrance of the actual photoprinting apparatus.
  • the device according to the invention contains three rolls of reproduction material of different widths, in particular photoprinting paper.
  • the reproduction material may also differ in other properties, such as its color.
  • the different widths are at a ratio of i 2 4, so that reproduction materials of 297 mm, 594 mm, and I 188 mm width may be used.
  • the outer front ends of the two narrower rolls are preferably in the same planes with the front ends of the widest roll.
  • Rolls of these widths are suitable for copying originals whose size ranges from size DIN A 4 to size 2 DIN A 0 (DIN Deutsche Industrie norm German Industrial Standard).
  • the copies obtained correspond in their length and width to the DIN size, without margin, whereas copies produced from originals not corresponding to the DIN sizes are cut according to the size of the original.
  • two additional rolls may be provided which normally will be of smaller diameter. These rolls may be stored either in the conventional manner, in a paper supply box of the feed table, and the desired length may be cut therefrom by means of a cutting wire, or they may be stored in a suitable location in the device on axes which are arranged parallel to the axes of the aforementioned three supply rolls.
  • photoprinting paper In order to avoid a frequent replacing of the supply rolls, normally several hundred meters of photoprinting paper are wound on each roll.
  • the length of the paper wound up depends upon its thickness and its weight per unit area. Of photoprinting paper of a weight of g per square meter, for example, about 600 meters may be wound upon a roll without making the roll too heavy for practical use.
  • the upper limit is determined by the fact that the lower roll or the lower rolls must still be accessible after the upper roll has been placed in position, to facilitate threading of a web or webs of material.
  • the diameters of the rolls range from ISO to 350 mm.
  • the two narrower rolls are arranged with their axes substantially in alignment with each other. Their axes may lie either on an imaginary common center line, or they may be slightly displaced relative to each other.
  • the axis of the widest roll is arranged parallel to the axes of the two narrower rolls.
  • the wide roll may be positioned below the two smaller rolls as shown in the embodiment illustrated by the drawings, or it may be placed above the two narrower rolls.
  • the apparatus consists of a stationary and a movable component.
  • the moveable component may be inserted into the stationary component and, in this position, forms the front cover of the apparatus. Due to their large diameters, the rolls are very heavy and can be manually handled or replaced only with difficulty. Therefore, one component of the apparatus is in the form of a movable carriage for conveying the rolls. It is provided with rocker arms by which the rolls can be lifted from the bottom by their axle ends and inserted into the holders in the stationary component of the apparatus.
  • the movable component is provided with a scale from which the elevation of the rocker arms can be read. The insertion of the rolls into the holders is thus further facilitated.
  • the draw-off rollers for the narrower paper rolls are in the form of hollow shafts, and a common driving shaft is constantly revolving in the centers thereof.
  • Each of the hollow shafts may be connected with the driving shaft by means of a clutch, so that paper may be withdrawn from either one of the rolls.
  • FIG. 1 is a simplified top view of the apparatus according to the invention, with the movable component partially inserted (feed table and conveyor means being omitted),
  • FIG. 2 is a section through the apparatus along line A-D of FIG, 1, the movable component of the apparatus being shown in a position separated from the stationary component,
  • FIG. 3 is a side view of a roll supported in a holder
  • FIG. 4 is a top view of this roll, with the holder and the connecting parts.
  • the apparatus consists of a stationary component 1 and a movable component 2.
  • the movable component 2 In the operational position, the movable component 2 is inserted into the stationary component 1 in such a manner that the front wall 3 ofthe movable component 2 is in alighment with the walls 4 of the housing of the stationary component.
  • the movable component 2 is provided with two rocker arms 5 and 6. F165. 1 and 2 show how these rocker arms hold a roll by its axle ends 7.
  • the rocker arms 5 and 6 may be lifted and lowered by means of a crank handle 8. This is indicated in HQ. 2 by the phantom positions 5', 6', and S", 6".
  • the movable componcnt 2 of the apparatus is provided with a scale 9 from which the elevation of the rocker arms 5 and 6 can be read through a window 10 in the front wall 3.
  • the dis tance ofthe rocker arms 5 and 6 can be adjusted along the front wall 3 in order to enable them to seize rolls of different width.
  • the stationary component 1 of the apparatus contains the two rolls l1 and 12, which are arranged with their axes substantially in alignment, and below these rolls is the wide roll 13.
  • Roll 12 is shown in FIGS. 1 and 2 in the alternate position 12" which it takes before being inserted into the stationary component 1.
  • the axle ends 7 of rolls ll, 12, and 13 are supported in the holders 14.
  • Rolls 11 and 12 are located in the compartment 15 of the apparatus which can be tilted to take position 15', with rolls 1! and 12 taking the positions H and 12', In this manner, the lower roll 13 is easily accessible.
  • the front ends 16 and 17 of the widest roll 13 are in the same planes as the front ends 18 and 19 of the two narrower rolls l1 and 12.
  • Paper webs 20 and 21 are drawn off of the supply rolls 1] and 12 and conveyed to the cutting station 28 over the pairs of draw-off rollers 22/220 and 23/23a,
  • paper web 29 is drawn off of the supply roll 13 and conveyed to the cutting device 28 over a pair of drawoff rollers 30f30a, a displaceable roller 3], and a pair of feed rollers 32/32u.
  • the paper is fed by means of rollers 33 and 34 to the exposure station (not shown).
  • the displaceable rollers 24 and 25 are moved in their rails 35 and 36 until they take the positions 24'and 2S.
  • the displace-able roller 31 can shift in its rails 37 to take the position 31.
  • the displaceable roller 31 is connected in such a manner (not shown in the drawings) to the compartment 15 ofthc apparatus, that it is shifted in its rails into the position 31, when compartment 15 is tilted into position 15. ln this manner. threading of the paper web 29 after replacement of roll 13 is substantially facilitated.
  • An original 38 is fed into the apparatus from a location on the feed table 39 which is determined by its width and is conveyed to the exposure station by the feed rollers 40 and 34.
  • the feed table 39 can be raised on hinges to the position 39', so that the two narrower rolls 1] and 12 are easily accessible.
  • the feed table 39 carries a box 41 for special types of paper.
  • the draw-off rollers 22, 23, and 30, which are associated with back-up rollers 22a, 23a, and 300, are in the form of hollow shafts.
