Description

The invention relates to deliassers for

  continuous machine prints, and more particularly

  a relatively small deliasseuse that can be

on a table or whatever.

  U.S. Patent Nos. 3,514,094, 3,944,206, 4,094,498 and 4,133,520 describe

  embodiments of the prior art.

  Trimmers for separating copies of continuous paper machine prints are used

  for a long time, especially in

  relatively large quantities of these prints.

  However, until now, companies have used

  very few delicatessens dealing with a relatively small volume of printed matter. These companies frequently use stationery bundles instead of printed

  continuous, or their clearing operations are carried out

  otherwise because the volume treated does not justify the acquisition of

  a disassembler that can be expensive and cumbersome.

  The ever-decreasing price of calculators and

  their printers resulted in increased use of

  continuous machine prints, even in

  relatively small companies that can now acquire

  their own calculator and printer system, so the need for these small businesses to own a

  deliasseuse is more felt.

  This need has not been met so far. Trimmers such as those described in the above-mentioned patents Nos. 3,514,094 and 3,944,206 are particularly designed for relatively large-scale operations and are generally too expensive for small operations. Therefore, efforts have focused on

  the manufacture of smaller and less expensive

  its, and devices of the type described in the above-mentioned patents Nos. 4,094,498 and 4,133,520 have appeared on the market. Nevertheless, these devices are unsatisfactory for a number of reasons. For example, in the case of the apparatus described in the aforementioned US Pat. No. 4,094,498, it is necessary to use edge guides and devices which resist movement to ensure proper dislocation and optimal folding. The use of such elements requires an important adjustment time before the start of the dicing operation and these elements obviously increase the cost of the deaerator. Moreover, the types of deliasseuses described in the aforementioned patents Nos. 094498 and 4 133 520 are incapable of deliassing and

  fold a large variety of printed di-

  different weights and weights, and each of these deliasseu-

  its default is that the surface supporting this deliasseuse

  should be used either as a stacking location for

  awarded to deliasser, or as a location for receiving parts of printed disassembled, or for these two functions. Therefore, none of these deliassers are

  autonomous and, although each of them may be of

  relatively small, it requires a table or other relatively large

of support.

  The invention is designed to solve one or more

previous problems.

  The subject of the invention is an improved deliator for continuous machine prints. The invention more particularly relates to a deliasseuse who deals with

  satisfactorily a wide variety of mechanistic

  which is ideally suited for reasons of low

  cost and small size, to companies in the-

  which deliassage operations to be carried out are few

important, and which is autonomous.

  An exemplary embodiment of a shredder according to the invention, corresponding to the aforesaid objects, comprises a frame which has an inlet end receiving multi-copy continuous machine prints, of which at least one copy is to be separated. At least

  two vertical partitions, horizontally spaced, are

  placed on the chassis and define at least two

  intended to receive corresponding parts of

  continuous and separate mechanistic awards. At least two feed rollers journalled on the frame and each extending across the top end of

  the corresponding one of the partitions, and a coil receiving

  The carbon tread, which is journalled on the chassis, extends approximately parallel to the feed rollers and is arranged at a distance between the partitions. A

  device is intended to rotate the feed rollers

  and the receiving coil at predetermined relative speeds so that the rotational force applied to the take-up spool is less firm than that applied

to the feed rollers.

  Due to the design described above, optimal folding is achieved on a wide variety of different sized machine size print types and

different paper weights.

  In a particularly advantageous form of

  of the invention, the rotation control device comprises a motor whose output shaft is connected by a

  transmission train to the feed rollers. A m-

  friction clutch with constant torque, set at a low

  ple, is mounted between the transmission train and the receiver coil, so that when the receiver coil is increasingly loaded by the sheets of carbon paper that accumulate there and that, therefore, its winding perimeter increases, its speed is reduced as a result of the sliding of the clutch to be adapted to the speed

  from one of the feed rollers.

  In this embodiment, it is advantageous

  that the drive train is mounted, compared to the rou-

  and the receiving spool, such that the peripheral speeds of the take-up spool and the roller furthest from the infeed end of the trimmer are substantially equal in the absence of slip of the friction clutch, and that the roll closest to the end

  input has a substantially lower peripheral speed.

  A very advantageous embodiment comprises only two partitions whose lower ends are connected by members constituting the bottom of an outlet station, a plate being mounted so as to slide in the frame, near the lower end. the wall farthest from the entrance end and on the far side of the nearest wall. The tray is extendable to form another exit station and the frame further comprises a lower horizontal extension passing under the inlet end and intended for

  receive a stack of machine prints to debond.

  This embodiment constitutes a deliasseuse

  totally autonomous, of small dimensions, which can be used

  in a way completely independent of the support on

which she rests.

  The invention will be described in more detail with reference to the accompanying drawings by way of non-limiting example and in which:

  entry of the deliasseuse, with partial tearing.

  Figure 1 represents an example of a form of

  the use of the deliasseuse according to the invention. This deliasseuse

  includes a frame indicated overall at 10. The end of

  The trencher is delimited by a tubular transverse element 12 disposed approximately horizontally and mounted on

  the frame 10, near the front end and the

  upper face of the latter. A fixed plate or extension 14 extends below the tubular member 12

  protruding from the bottom of the frame 10. A stack of mechanical printed

  continuous, screen-folding graphics to be disassembled is placed on the surface 14 before the start of an operation

of deliassage.

  A first approximately vertical partition 16, located

  immediately behind the tubular element 12, constituting

  kills the entrance end of the deliasseuse. A second, approximately vertical partition 18 is spaced horizontally

  of the partition 16, behind the latter. The cloisters

  16 and 18 are suitably attached to the frame 10 and

  partly define two different

  born in separate parts of a machine

  tinu deliassé. In this regard, a plate 20 extends between the lower ends of the partitions 16 and 18 and is fixed to the frame 10 to form the bottom of a first of these

exit posts.

  Feed rollers 22 and 24 are arranged

  at the upper ends of the partitions 16 and 18, respectively

  is lying. The feed rollers 22 and 24 extend

  versalement, along the upper ends of the partitions 16 and 18, and they are mounted to journal in

  the frame 10 around approximately horizontal axes.

  A carbon-receiving coil, indicated globally

  26, located in the space between the partitions 16 and 18 and close to the upper end thereof, is mounted so as to be able to

  the frame 10, around a roughly horizontal axis, that is

  that is to say an axis approximately parallel to the axes of rotation of the rollers 22 and 24. As is well known, during a deliassage operation, the intercalated carbon paper, if

  is present, is driven on the coil 26.

  The assembly is completed by a control panel located on the end of the tubular element 12 remote from the

chassis 10.

  As shown in FIG. 4, the tubular element 12 internally carries an electric motor 32 comprising an output rotary shaft 34 intended to control the delisasseuse

  as described below. The electric motor 32 is preferably

  The variable speed type is implemented by means of suitable controls (not shown) housed in the control panel. A bar 36, suitably fixed

  to the frame 10, for example by means of a bolt 38, is

  placed immediately below the tubular element 12 and extends approximately horizontally and parallel to the axes of rotation of the rollers 22 and 24 'and at the front edge of the element.

  tubular 12-. Bar 36 is generally not used.

  during a clearing operation. However, in the case of printed copies of which are fixed relatively securely to each other, for example by many methods of crimping paper, during the preparation of the delisasseuse, the print is passed between the upper side

  of the bar 36 and the lower surface of the tubular element

  12 before being passed over the first feed roller 22. Normally, this is not necessary, to which

  case the print simply went over the front edge of the

  tubular element 12, then on the first roller 22 of food

  tation. A so-called carbon deflection bar (FIG. 3) is disposed in the pocket formed between the partitions 16 and 18, close to the upper end of this pocket, between

  the roller 22 and the receiver coil 26 of the carbons,

  to be relatively close to the roller 22. The bar

  of carbon deflection is parallel to the rotational axis

  the roller 22 and is fixed in place, for example by means of a nut 42. When setting up a machine print to be deliacerated in the machine, the portion of the print to accumulate in the pocket formed by the partitions 16 and 18 is passed between the carbon deflection bar 40 and the partition 16 so as to be folded over the bottom 20 of the pocket by means of a folding plate 44 (FIG. 2) which can to be fixed by a magnet 46 at any point

desired from the bottom 20.

  Any carbon sheet adjacent to the portion of the print accumulated in the pocket defined by the partitions 16 and 18 and to be removed is passed in the same manner between the carbon deflection bar 40 and the partition 16, and is then directed to the receiver coil 26 on which it is wound sufficiently to provide training

  carbon during the rotation of this reel

ceptrice 26.

  The remaining portion of the print is passed over the roll 24 to be retrieved on a platen 50 of

  approximately L-shaped. The plate 50 has a long wing.

  52 (Figure 2) which can slide in slides

  in the chassis 10, immediately

  below the bottom 20. Therefore, the plate 50 can be advanced to the left for a distance from

  the position shown in Figure 2 to form a

  manages to receive the part of the print that is de-

  bunched and passes over the roller 24. A pressure roller 56, which journalled on an L-shaped rod 58 pivoting on the frame 10 by means of a bracket 60, is

  used to properly apply the print against the perimeter

of the roller 24.

  Therefore, the tray 50 constitutes a second output station. Since this tray can be pulled out of the chassis or retracted inside the chassis, as

  shown in Figure 2, it appears that the whole of the

the scope of the invention.

  The rotary shaft 34 of the output of the motor 32 carries a small pulley 70 and a belt 72 passes over this pulley as well as on a relatively large pulley 74. A small

8 2484379

  pulley 76 is connected to the pulley 74 to rotate with it about the indicated axis and a belt 78 extends from the pulley 76 to a first pulley 80 mounted on the drive shaft 82 of the first roller 22. By therefore, when the motor 32 is rotated, the driving roll 22 is rotated in the opposite direction to the needle

  of a watch, as shown in Figure 2.

  A pulley 84, also mounted on the axis 82 of

  Trailing, as shown in Figures 3 and 4, receives a belt 86 which also passes through a groove in the outer surface of the input side of a clutch 88 to constant torque and fixed setting. This clutch 88 may be a clutch of the friction type and its output element is connected to a drive shaft 90 of the receiver coil 26.

carbons.

  The outer peripheral edge, or input side of the clutch 88, has a second groove (not shown) receiving a belt 92 which also passes over a pulley

  94 fixed on a drive axis 96 of the second roller 24.

  Because of this design, it appears that the rollers 22 and 24 are driven relatively firmly, the first by a belt connection with the pulley 80 and the second by a belt connection between the pulley 84 and the inlet side of the pulley. clutch 88 and the pulley 94 and the

  transmission belts. Conversely, the coil 26 recep-

  trice of carbons is only forced to the extent

  o The torque at which the clutch 88 is set is not exceeded.

  In this regard, it should be noted that the connection made with the roller 24 bypasses the clutch 88, since the belt 92 rotating the pulley 94 passes around the inlet side of

  the clutch 88 and not on its output side.

  It is highly desirable that the torque of the clutch 88 be set to a relatively low value. He appeared

  that the adjustment of the clutch must advantageously be effected

  such that the clutch 88 does not transmit a torque greater than a value of the order of 0.011 to 0.11 mN, and the adjustment is preferably made so that the clutch 88 does not transmit to the take-up spool carbons a

  torque greater than 0.022 mN, plus or minus 0.011 mN.

  The perimeters of the rollers 22 and 24 and the useful perimeter of the receiver coil 26, without accumulated carbons, as well as the size of the various pulleys and outer grooves of the clutch 88, are preferably chosen so that, in the absence of carbon accumulated on the receiver coil

  26 and without sliding of the clutch 88, the speeds

  The receiver coil 26 and the second roller 24 are approximately equal, and the peripheral speed of the roller 22 is 10% lower. This gear ratio and torque setting ensure optimal folding of a wide variety of different size prints and paper weights. The use of the clutch 88 with torque

  fixed, set at a relatively low value, ensures the

  the peripheral speed of the receiver coil 26 to a value equal to that of the roller 24 although, as is obvious to those skilled in the art, the perimeter of the

  receiving coil 26 increases as the accumula-

  carbonation on this coil. In particular, when

  that the carbons accumulate on the coil 26, the total weight to be rotated by the force transmitted by

  the clutch 88 increases, as does the moment arm

  both from the center of the axis 90 and ending at the point where the carbon sheets come into tangential contact with the

  accumulated carbons, which causes a shift in

  clutch 88, so that the takeup spool 26 can not pull through the trimming machine at a faster rate than they pass on the faster rotating roller 24. In this respect, the roller 22, which is slower, produces a slight restraint, because the printed deliassé

  is pulled on this roll by the roller 24 rotating faster

  Dement. At the same time, since the roller 22

  turns, the restraining force is insufficient to

  It follows from the preceding description that the

  Delisoreuse according to the invention satisfies the various objects indicated above, namely that it is relatively inexpensive to manufacture, a little complex adjustment, because

  edge guides or independent restraint devices

  are eliminated, it produces an optimal folding of a wide range of sizes and types of printed papers, presenting various weight of paper, and that it is completely autonomous in order to be able to be implemented quite

  regardless of the surface carrying it.

  It goes without saying that many modifications can be made to the deliasseuse described and represented without
