Definitions

  • the subject of the present invention is a method for producing a bundle capable of forming at least one bellows filing cabinet, consisting of a selected plurality of partitions and of an accordion-pleated bellows connecting the partitions in pairs. on three sides, and a machine for implementing such a process.
  • Binders are known for the storage of documents which consist of an accordion-fold bellows, and inside which parallel partitions secured to the folds of the bellows form pockets in which documents can be classified.
  • Such binders are produced by hand, that is to say individually and manually, from which various operations result for the formation of the folds of the bellows, the preparation and the installation of the partitions in folds, as well as various finishing operations.
  • US Pat. No. 1,968,165 teaches a process for producing a bellows filing cabinet according to which the partitions are glued onto a defined marginal area and on three sides, then inserted into the folds of an accordion bellows, the assembly then being transported to a machine capable of compressing it using rollers.
  • the present invention seeks to remedy such drawbacks set out briefly in the foregoing, and for this purpose proposes a method of manufacturing a bundle capable of forming at least one bellows file cabinet with a selected plurality of pockets and a machine for the implementation of this process, according to which, with reduced labor, not only high production rates are obtained, but a product with an integrity finish.
  • the method of producing a bundle capable of forming at least one bellows filing cabinet consisting of a selected plurality of parallel partitions previously glued along three sides on a marginal area, which are inserted in a bellows with accordion folds and pressed to connect by glue two by two said partitions by three sides, thus forming storage pockets, is characterized in that, starting from a flexible strip, suitable for the formation of such bellows, we form it in a U along its longitudinal axis, then, having pulled forward a length of strip of a dimension equal to the development of a fold of the bellows, we place at the rear of this length, perpendicular to the longitudinal axis, a precut partition having on at least two sides a folded and glued tab, then a fold is made in the median zone of this length, by a pushing from the outside to the inside on the three sides of the U-band, and o n press the fold thus formed in an axial direction until it is crushed so as to ensure the bonding of said partition
  • the invention provides a machine which is characterized in that it comprises on a frame, following the longitudinal axis of the strip, and from back to front, the rear being a location where the strip is wound on a reel, and the front a location where the bundle is produced, a profiled element capable of gradually giving the strip a U-shaped section, traction means capable of pulling a length of strip in U corresponding to the development of an accordion fold to be formed, pushing means arranged laterally on the three sides of the strip formed in U, these means being movable back and forth in a direction substantially perpendicular to the axis of the U-shaped band, means capable of pressing a fold that has just been formed, retractable retaining means capable of holding the bundle during the formation of a fold, and means capable of slowing the bundle in its forward progression .
  • the machine is completed, according to another characteristic of the invention, by a partition distribution station arranged substantially overhanging the length of the drawn strip, and essentially comprising a plate movable between a substantially horizontal position for which it receives a partition with folded and glued tabs and a substantially vertical position for which it is inserted, with the partition, at the rear of the length of strip drawn; the face of this plate carrying the partition being connected to a source of vacuum so that the partition is maintained during its transfer.
  • the machine is also supplemented at its front end, by means capable, on the one hand, of retaining the bundle formed, and, on the other hand, allowing it to be cut off for obtaining d 'a bellows filing cabinet, such means being essentially constituted by a frame movable vertically on uprights, which frame is arranged to penetrate a fold, and to allow the sectioning of the bundle using a cutting tool.
  • Such a machine has undeniable advantages compared to the prior art; it allows, practically without manual intervention, the realization in continuous automatic, of bundles from which one can draw a multiplicity of bellows binders having a selected plurality of partitions linked to the bellows by forming pockets for the storage of documents.
  • the machine comprises a frame generally indicated by 10 carrying at the rear a coil 11 on which a strip 12 is wound, for example made of canvas paper; the reel 11 with the associated strip is rotatably mounted on a frame 13 carrying guide and return rollers 14 to 18 so that the strip 12 is presented at the rear end of the frame 10 of the machine and in the upper part of that -this.
  • the strip 12 is progressively formed in a U along its longitudinal axis, by means of a profiled element 20 associated with the chassis, which profiled element extends generally from the roll 18 to two lateral rollers 21, 22, with axes vertical, capable of pressing over their entire height, the lateral sides of the strip thus formed in a U against the vertical walls of the above-mentioned profiled element.
  • a block 26 suspended from the frame 10 by attachment means 27 themselves slidingly mounted in a support 28 secured to the frame 10 is arranged to receive a jack 30, the piston rod of which is equipped with a generally rectangular base 31 of which the front wall 31A is connected by channels 31 B and pipe 31C to suction means not shown.
  • the dimensions of this base both in height and in width correspond substantially to the U-shaped profile of the strip; the bed 31 being coupled to the jack 30, it is therefore movable longitudinally between an advanced position and a retracted position.
  • the amplitude of the movement of the bed base can be adjusted as a function of the length of strip to be pulled by the sliding mounting of the attachment means 27 in the support 28 (fig. 1).
  • the jar of this jack has a radial extension 38 (fig. 3), the end of which is provided with a roller 39 is engaged in a fork 40 fixed on the rear face of the box spring 31.
  • the box spring 31 has two functions, namely: ensuring the pressing of a fold formed, and simultaneously driving the U-shaped band forward of a length corresponding to the development of a fold.
  • the forward drive of the U-shaped band is obtained by means of side-clamps arranged substantially at the level of the bed base, along the three sides of the U-shaped band.
  • These sidewalls include a frame 45 surrounding the U-shaped band; this frame is fixed by one side to the upper edge of the box spring 31 and is therefore movable therewith, the other three sides of the frame each carry a pressing device constituted by a strip 46, arranged opposite the sides of the this box spring being itself coupled to a small cylinder 47 fixed to the frame.
  • the frame 10 carries laterally on the three sides of the U-folded strip, folding units indicated generally at 50 capable of forming an accordion fold in the length of the pulled strip, and retaining units able to hold the formed bundle indicated as a whole at 51.
  • the three folding units 50 thus arranged to form a fold of the bellows being similar in their construction and only one will be described in the following.
  • Each folding unit 50 comprises a first carriage 52 mounted movable perpendicularly to the axis of the strip folded in a U on a fixed slide 53 and this, using a jack 54 to which the aforementioned first carriage is coupled.
  • the first carriage 52 is arranged (fig. 4 in particular) to form bearings 56, 57, with an axis 58 whose ends - protruding with respect to said first carriage - are coupled with discs 59, 60, themselves coupled with crank pins 61, 62, wedged on arms 63, 64, forming a second carriage 65 which carries a folding blade 66.
  • Substantially in the middle of the axis 58 receives a pinion 70 capable of cooperating with a rack 71 which can be driven in translation by means of a jack 72 which is associated with it.
  • each folding unit 50 capable of forming the folds of the bellows comprises two axis, pinion, and crankpin assemblies as described above, driven by a single rack.
  • the folding blade 66 fixed to each folding unit has a terminal edge 66A, parallel to said sides of the strip formed in a U shape.
  • the folding unit arranged opposite the base of the U formed by the strip comprises a folding blade which extends at least over the entire length of this base, while the associated folding blades the folding units arranged opposite the sides of the U are slightly shorter than these sides; they are arranged in such a way that their respective lower ends are at some distance from the base of the U. Such an arrangement is necessary to allow the simultaneous formation of a fold of the bellows on the three sides of the U-shaped strip.
  • Such a retaining unit comprises a lever in the shape of a stirrup 75 facing one side of the strip, this stirrup is pivotally mounted on a pin 76 fixed to the end of the slide 53 and extends on either side of this axis being, at one front end, connected to a return spring 77 associated with a tension adjustment device 78 secured to the fixed slide 53, and at the other end equipped with a retaining head indicated as a whole by 79.
  • the end face of this retaining head (fig.
  • Another complementary restraint unit indicated generally at 90 in FIG. 1, is provided to cooperate with the upper edge of the last partition in place; this retaining unit is carried by a cross member 91 secured to the frame, and it comprises a jack 92 whose pot is pivotally mounted on a bracket 93 provided at the upper end of a vertical arm 94 fixed to the cross member, while the piston rod 95 of this jack is coupled to a lever 96, mounted by a pivoting end on the aforementioned vertical arm, the other end of this lever 96 comprising at least one claw 98.
  • the aforementioned claw 98 as well as the claws 81 fixed to the retaining units 51 may each be in one piece extending over the greater part of the sides of the U, and of the upper edge of a partition, but they can be made up of several elements attached to the end of levers 75 and 96.
  • a partition supply device indicated as a whole by 99 is carried by the frame 10
  • This device (FIG. 1) comprises a plate 100 extended forwards by an arm 101, carrying a roller 102, able to cooperate with a ramp 103 arranged in an arm 104 extending vertically.
  • the plate 100 is coupled by axis 107 to the piston rod of a jack 108 itself carried by a cross member 109 fixed to cheeks 110 fixed to the frame.
  • the face of the plate 100 intended to carry a partition 113 is connected by pipeline 112 to a source of vacuum (not shown here); this tray is suitable for transferring a partition 113 from a substantially horizontal position where said partition is disposed on the tray at a substantially vertical position situated at the rear of the developed length of a fold to be formed, as will be seen further.
  • the partition 113 has on three sides tongues 114 folded and glued, and it is arranged on the plate 100 so that said tongues are in the case considered - after the formation of a fold - facing the rear face of the fold formed, as is clearly visible in particular in FIGS. 10 to 13, the tongues being cut so that they follow the vertical sides as well as the horizontal lower side of the fold.
  • the frame 10 carries two pressing rollers 115, 116 (figs 1 and 2) mounted to rotate around vertical axes, they are adjustable in spacing and adapted to effect a braking effect on the vertical sides of the bundle indicated as a whole by which it rests on a support table 118.
  • the machine is completed by means of retaining the bundle L generally indicated at 120, these means being also adapted to allow the cutting of the bundle in order to constitute a bellows filing cabinet with a chosen plurality of pockets.
  • the retaining and cutting means essentially comprise (FIGS. 5 to 7) a frame 130 mounted vertically movable by its uprights between two pairs of guide rollers 131, 132, rotatable on a frame 133 fixed to the frame.
  • the frame has on its front face an operating handle 134, and it is associated by cable 135 and pulley 136 with a counterweight 137.
  • the uprights of the frame 130 have grooves 140 able to cooperate with the guide rollers 131 , 132.
  • the uprights of the frame 130 have in a median zone recesses 139 from which the grooves 141, 142 extend downwards, in parallel with the grooves 140.
  • the lower edge of the frame has a throat 143.
  • the lower edge of the frame has bevelled front and rear faces 145 in order to facilitate the introduction of the latter between two consecutive partitions, therefore inside a pocket, while the thickness E of this frame (fig. 7 ) is capable of ensuring the deployment of a fold of the bellows in order to facilitate the transverse cutting which is effective carried out manually using a blade guided by the aforementioned grooves 141 to 143 formed in the frame.
  • all the retaining units 51 arranged laterally and below the strip 12 formed in a U are in the active position, as is the upper retaining unit 90, so that the last partition 113 is retained by the claws associated with each unity, that is to say on its four sides; it will be noted that the aforementioned retaining units are active by the springs 77 and the tension adjustment devices 78.
  • the bed base 31 is in the rear position, the side clamps 46 are in the active position and clamp the strip 12 against the bed base 31, the folding blades 66 of the folding units are in an intermediate position and a strip length "LB", of length equal to the extent of a fold, is provided between the last partition 113 and the front face of the bed base 31.
  • the bed base 31 continues to move forward and initiates the pressing operation of the fold just formed in order to stick the tongues to the corresponding faces of the fold, while the first carriages 52 are moved along the arrow F5 by pressurizing the associated cylinders 54 so that the folding blades 66 pass from an advanced position to a retracted position, the cylinders 72 associated with the second carriages 65, being in turn, kept under pressure to maintain the blades folding in a position identical to that shown in fig. 10, for which the cam 83 is engaged in the clearance 80.
  • the displacement of the first carriages has the effect, on the one hand, of disengaging the folding blades 66 from the hollow of the fold formed, and, on the other hand, of bring the cam 83 into contact with the ramp 82 provided in the retaining units 51 and drive the lever 75 (arrow F6) by pivoting about its axis 76 from an active position (FIGS. 8 to 11) to an erased position set back (fig. 12).
  • the lever 96 of the upper retaining unit 90 is also erased by means of the jack 92 so that the four sides of the U-band are released for the operation of pressing.
  • the cams 83 release the levers 75 which automatically return to the active position (arrow F9) under the effect of the springs 77, position for which the claws 81 hold the last fold form.
  • the new length LB ′ is formed at the same time as the formation of the fold because the three sides of the U-shaped strip are driven simultaneously by the advance of the bed base 31 and this, by means of the clamps 46 which make the U-shaped band temporarily secured to the bed base 31, (FIGS. 8 to 12), while at the end of pressing, before the bed base 31 returns back, the side clamps 46 are rendered inoperative; in fact, said side-clamps are inoperative only during the stroke towards the rear of the bed base 31.
  • the bundle L capable of forming at least one pocket binder is guided and slightly braked in its advance by the pressure rollers 115, 116, so that the folds are tightened by then the formation zone up to these pressure rollers, which ensures good bonding of the partitions.
  • the frame 10 is advantageously equipped with means for retaining the bundle L produced, these means being able to allow easy cutting of the bundle to constitute a bellows filing cabinet, with a selected plurality of partitions forming pockets of storage.
  • the frame 130 is normally in the low position and forms a stop at the front end of the bundle L; to cut the frame 130 is reassembled using the handle 134, which allows to release a desired number of folds of the bellows and associated partitions and therefore pockets.
  • Such an operation is carried out manually, and when a selected plurality of pockets is obtained, the frame 130 is lowered by inserting it into a pocket between two consecutive partitions; it will be noted that the two partitions considered are manually moved aside in order to favor the insertion of the frame between them, and the frame is lowered until it abuts on the table.
  • the accordion fold concerned is completely stretched and the actual cutting is practiced using a sharp blade which is guided along the grooves 141, 142, 143, so that the fold is sectioned on its three sides in its median zone given the median location of said grooves in the thickness of the frame.
  • the bellows file thus obtained with a selected plurality of pockets resting on a table 121 extending the table 118 is then evacuated, and a new cutting can be carried out, in parallel with the formation of new folds.
