Description

The invention relates to a method and a device for producing information-provided windings from the information-carrying sheets, as well as windings produced by the method.

Known compact record carriers, such as, for example, leaflets or multiple-fold instructions for use added to the medicinal products, are generally folded in the manner of concertina folds or in some other way. Here, a multiple printed sheet is first folded up accordingly, which is then cut into the individual folded recording media. This requires a relatively slow and expensive machine equipment, which leads to high costs.

It was therefore the object of the invention to provide a compact recording medium which does not tend to unintentionally dissolve, but which can be opened very easily for reading, and which can furthermore be produced extremely quickly with a relatively cheap device using a simple method, as a result of which the manufacture is significantly cheaper.

The inventive solution to the problem consists in the s

Figure 4 of the drawing shows a multiple sheet 210 made of paper or other suitable flexible and foldable sheet material. In the example shown, the arch 210 is generally rectangular with a longitudinally extending lower edge 211 and an upper edge 212 parallel thereto, and with mutually parallel side edges 213 and 214 which run perpendicular to the upper and lower edges. Formed in sheet 210 are a plurality of parallel notches or folds 216, 217, 218, 219, 220, 221, 222, 223 and 224, which are at substantially equal mutual distances parallel to one another from lower edge 211 to upper edge 212, on these standing vertically. The folds 216 through 224 cooperate with the sheet bounding edges 211 through 214 to divide the sheet 210 into a plurality of generally rectangular columns or fields that are adjacent to each other and through their adjacent lateral edges different notches or folds 216 to 224 are connected to one another in a hinge-like manner.

The sheet 210 is further divided or separated into a plurality of generally rectangular, elongated line-like strips by a plurality of cuts or dividing lines 226, 227 and 228, which are equally spaced parallel to each other in the longitudinal direction of the edges 211 and 212 between them cut the side edges 213 and 214 at right angles. Sheet 210 can be considered a group record carrier that is divided into a plurality of substantially identical strips

230, 231, 232 and 233 is cut or separated. Specifically, elongated strip 230 is delimited by side edges 213 and 214, top edge 212 and bottom dividing line 226, strip 231 by side edges 213 and 214, and top and bottom longitudinal dividing lines 226 and 227, strip 232 by FIG the side edges 213 and 214 and the upper and lower longitudinal dividing lines 227 and 228 and the strip 233 from the side edges 213 and 214, the upper dividing line 228 and the lower edge 211.

All strips 230 to 233 are essentially identical, so only a single one of the strips needs to be described in detail. This single strip 230 is divided into a plurality of substantially identical, generally rectangular panels or panels 235 to 244 by the lines dividing it, namely the notches or folds 216 to 224, side by side with their abutting edges hinge-like are connected to one another via the respective notches or folds 216 to 224 located therebetween. In particular, the field 235 is delimited by the dividing line 226, the side edge 213, the upper edge 212 and the fold 216; the field 236 is bounded by the dividing line 226, the fold 216, the upper edge 212 and the fold 217; the field 237 is delimited by the dividing line 226, the fold 217, the upper edge 212 and the fold 218; the field 238 is bounded by the dividing line 226, the fold 218, the upper edge 212 and the fold 219; the field 239 is delimited by the dividing line 226, the fold 219, the upper edge 212 and the fold 220; the field 240 is delimited by the dividing line 226, the fold 220, the upper edge 212 and the fold 221; the field 241 is delimited by the dividing line 226, the fold 221, the upper edge 212 and the fold 222; the field 242 is delimited by the dividing line 226, the fold 222, the upper edge 212 and the fold 223; the field 243 is delimited by the dividing line 226, the fold 223, the upper edge 212 and the fold 224; and the final field 244 is delimited by the dividing line 226, the fold 224, the upper edge 212 and the side edge 214. The fields each lie within this limitation.

Furthermore, suitable informative information according to the needs of the individual case is attached to at least one surface of the strip 230 by printing or marking. The edge field 235 is provided with an imprint 245 and the edge fields 236 and 237 are provided with a common imprint 246. In the same way, the adjacent fields 238 and 239 are provided with a common print 247 and the adjacent fields 240 and 241 with a common print 248. The individual field 242 bears an imprint 250 which, as can be seen, maintains a distance from the central region 251 of the field and thus leaves this central region unmarked.

The field 243 adjacent to the edge field 244 and connected to it in a hinge-like manner can be regarded as a title or cover field and bears title or identification information 252, while the edge field 244 can remain without printing if desired.

Folded coils 330 shown in FIGS. 1 to 3 are produced from the strip 230. For this purpose, the sheet 210 is cut along the dividing lines 226, 227 and 228 to form a plurality of the strips, each of which forms a winding 330. Each of these folded coils 330 has an inner panel 335, which is connected by a hinge-like fold line 316 to a next adjacent panel 336, which is bent around the fold line 316 so that it lies essentially congruent with the innermost panel 335 thereon is coming. Furthermore, a next adjacent field 337 is connected to the outer edge of the field 336 via a fold line 317, which is connected via this hinge connection s

the folding line 317 is articulated on the other edge of the field 336 and is folded over the hinge construction in a congruent opposite position with respect to the innermost field 335, namely on its side opposite to the folded field 336. At its edge, which is distant from the hinge connection or fold line 317, the field 337 is connected via a notch or fold line 318 to an identical, generally rectangular field 338, which, via the hinge connection of the fold line 318, is in substantially congruent contact with the various inner fields 335, 336 and 337 worked. In addition, the field 338 is connected on its side remote from the fold line 318 via a fold line 319 to a generally rectangular, substantially congruent field 339, which is folded around the fold line 319 opposite the various fields 335 to 338. And around another hinge fold line 320, another panel 340 is connected to its adjacent panel 339 and folded in congruent opposite relationship to that and the panels therebetween.

The panel 340 is hingedly connected to another general rectangular panel 341 via another fold line 321, which is folded around the fold line 321 in congruent opposite relationship with the various inner panels previously described and with a hinge-type connecting fold line 322 which faces away from the fold line 321, is connected to a further generally rectangular field 342, which in turn is folded in a covering relationship with the various inner fields. Finally, a title field 343 is hingedly connected to the field 342 via a notch or fold line 323 at a distance from the fold line 322 and folded in a covering relationship to the inner fields, while an outermost field 344 is folded behind a fold line 324 with respect to the title field 343.

The various panels 335 to 344 are thus all spirally wound and flattened in a generally planar, substantially rectangular pillow-like configuration, with each hinge-connected flattened pair of panels being on opposite sides of a median plane of the pillow-like configuration.

The generally planar, cushion-like wrap 330 is effectively fixed in its closed cushion configuration by suitable securing means such as an adhesive 355 placed between the outermost end panel 344 and its adjacent panel 342.

The middle region 251 between the imprints 250 on the field 242 enables the adhesive connection without spoiling the imprint 250. With its flat spiral shape and the retention of the shape of the various fold lines 316 to 324, the folded wrap 3300 maintains its flat configuration. It can also be attached to any suitable container, for example a can or the like, by adhesive or other connection. In this way, the wrap can be removed from the associated container, if desired, without inadvertent or inadvertent removal, and can finally be opened and the printed instructions can be followed without the print being affected in any way by the adhesive or otherwise.

For example, the various areas with the imprints 246 to 250 are exposed in such a way that they lie on one side of the unwound strip. In the event that the strip 230 is provided with the same printing as described on its opposite sides, the different strips can, if desired, be wound in any winding direction.

5 to 7 show a device 20 for the production of such coils with a base 21 which has an upper

Base plate 22 has. Above a generally central area of the base plate 22 is a generally horizontal tool table 25, which can also be referred to as a tool bed or support, for example a suitable rigid plate, which is held vertically adjustable, for example by vertical stands 26 and 27. The horizontal tool table 25 and the stands 26 and 27 thus together form a lifting device for purposes described later. In the example shown, the stands 26 and 27 are threaded elements reaching down into the base 21 and are mounted therein in such a way that there is only one degree of freedom for a vertical longitudinal movement; they are operatively connected to collars or nuts 28 and 29 screwed around them, which have only one degree of freedom for a rotary movement and are rotated by a drive machine 30 via suitable drive transmission devices 31. The table 25 thus forms a lifting device on which a stack of generally horizontal arches 35, of which the uppermost arch is to have a given height, can be stacked.

Two guide rails 36 and 37 are mounted on the base plate 22 parallel to one another and at a mutual distance from one another on opposite sides of the tool table 25, on which they extend in part. In each of the guide rails 36 and 37, a slider 38 and 39, which is adjustable in the longitudinal direction, is guided. The sliders 38 and 39 can slide along the respective guide rails 36 and 37 in the longitudinal direction and can be releasably fixed in place there with the aid of suitable fastening means such as clips 40. An upright column 41 and 42 protrudes from each of the sliders 38 and 39; columns 41 and 42 are bridged by a side bridge extending between their upper ends. The bridge 43 and its lateral columns 41 and 42 supporting it are selectively displaceable as a unit along the length of the guide rails 36 and 37, the bridge 43 spanning the tool table 25 of the lifting device at a distance.

An upright bracket or column 45 or 46 projects from each of the side guide rails 36 and 37, adjacent to the inner edge thereof. From each of the columns 45, 46, a threaded element in the form of a screw 47 or 48 extends inward through the column and carries at its inner end a stack guide 49 or 50 running in the longitudinal direction. These stack guides 49 and 50 are elongated rods which are arranged on the opposite longitudinal edges of the stack of sheets 35 so that the stack is fixed to the tool table 25. For this purpose, the stack guides 49 and 50 are carried by the respective screws 47 and 48, respectively, so that they can be moved in their mutually parallel relationship to and from each other by rotating these mounting screws. In addition, in the example described, the stack guide 50 carries a switch 51 serving as a stack height sensor with a finger 52 serving as a sensor element. The switch 51 is connected via electrical conductors 53 to the drive machine 30, which raises the tool table 25 to an upper limit position, which is caused by the lifting of the finger 52 on the uppermost sheet 35 of the stack.

The bridge frame 41, 42 and 43 carries on the bridge 43 a cylinder 55 with an internal piston and a piston rod 56 which projects downward through the bridge 43. From the lower end of the piston rod 56 extends a downward rod or piston rod extension 57, to the lower end of which a transverse rod 58 is connected, which lies in the area between the columns 41 and 42 and ends with its opposite ends close to these columns. The transverse rod 58 carries a plurality of glue applicators 60, which s

extend inwardly from the rod 58 and each have a downward nozzle 61 or other outlet with a downward valve stem or actuator 62. The combination of the transverse rod 58 and the plurality of glue application devices 60 can be displaced in the vertical direction by moving the piston rod 56 and the piston rod extension 57 up and down, which is controlled by the actuation of the cylinder 55. When the various nozzles 61 move downwards until the actuator 62 engages an object underneath, thereby lifting the actuator relative to its associated nozzle 61, an internal valve is opened and a portion of glue is thereby dispensed. The various glue application devices 60, the rod 58 and the nozzles 61 can thus be regarded as a vertically displaceable glue head which, when it moves downwards, applies a series of glue points to this uppermost sheet until it touches the uppermost sheet 35 of the stack.

Each nozzle 61 is connected to the lower end of a tubular or hose-like glue line 65, the upper ends of which are connected to a glue distributor 66 arranged above it, which carries a glue storage container 67 on its upper side. The glue distributor 66 and the storage container 67 are fixedly mounted by suitable fastening means, while the glue application devices 60 reciprocate and the flexible glue lines 65 bend.

Extending in fixed relationship between the columns 41 and 42 and spaced below the bridge 43 is a traverse or lower bridge 68 from which a plurality of inwardly or forwardly protruding finger-shaped projections 69 extend, which over the adjacent part of the uppermost arch 35 of FIG Stack ends in free ends 70. In the example described, two finger-shaped projections 69 are shown, but it can also be more or less if desired. From the free end 70 of each projection 69, a spitting element protrudes downward, namely a pointed holding element 71, which pierces into and through the uppermost and second uppermost arches 35, for reasons that will be explained below.

At the opposite end of the table 25 carrying the stack from the glue applicator 60 is a generally horizontally arranged, transversely extending hollow or tubular mandrel 75. As particularly shown in FIGS. 5 and 6, the glue applicator 60 and the various ones Glue nozzles 61 arranged over one of the edges of the top sheet 35 of the stack. The mandrel 75 is located over the opposite edge of the top sheet. Along its length, it has a longitudinal row of through openings 76 which communicate with the interior of the dome, while one end 77 of the mandrel is closed (Fig. 5,7). Averted from the closed mandrel end 77 is a pin or pivot bearing 78 on one side of the table 25, which holds the mandrel 75 mounted so that it can rotate axially. Via the bearing 78, a vacuum connection line 79 communicates with the interior of the mandrel 75, which on the other hand is connected in the direction of an arrow 80 to a vacuum source. A motor 85 with a suitable gear 86 is connected via a drive transmission device 87 to the rotary bearing 78 for driving the mandrel.

A stripping device 90 is mounted on the base plate 22 outside the mandrel 75, along it. This device comprises two transverse rails 91 which are firmly anchored to the base plate by end plates 92 and 93. A carriage 94 can be moved back and forth along the rails. A piston-cylinder unit 95 for driving (FIG. 7) is mounted on the base plate 22 and has two rollers 96 and 97 on the opposite cylinder sides, around which the pulling cables 98 and 99 are placed. Each of the cables 98 and 99 has one end connected to the piston of the cylinder 95

and connected at the other end to carriage 94 and running around rollers 96 and 97, respectively. Cylinder 95 has fluid ports 100 and 101 which control the desired displacement movement of piston and carriage 94.

The stripping device 90 also includes a base 102 in the form of an upstanding arm which is attached to the carriage 94, and a rod 103 which extends rigidly from the base 102 generally parallel to the mandrel 75. A generally horizontally extending arm 104 is connected to the rod 103, for example via a sleeve 105 ′, which extends outwards from the rod into a position above the mandrel 75. 8 and 9 in particular, two claws 105 are articulated on the arm 104 and hang down from the arm on opposite sides of the mandrel 75. Resilient means, such as a helical tension spring 106, are inserted between the claws 105, which resiliently urge the claws 105 to lie against the mandrel 75. An upwardly extending fluid cylinder 107 mounted on arm 104 has a downwardly projecting rod 108 that is provided at its lower end with a cam or roller member 109 that can engage between claws 105 to counteract the restoring force of spring 106 open to open.

In addition, the rod 103 carries a swinging arm 106 'at a distance from the arm 104 and the claws 105, which carries at its outer end a roller 107' which rests on the mandrel 75 in a rolling manner.

At a distance from the end 77 of the mandrel 75 and adjacent and in alignment with it is a folding device 110 with two generally tangential rotating rollers 111 and 112, the bay or roller gap of which is aligned with the mandrel 77. For the drive, a motor 113 is arranged above the rollers 111 and 112, which drives the rollers via a drive transmission device 114. The rollers are mounted in a housing or frame 115, on which the drive device 113, 114 is also mounted. In addition, a guide sleeve 116 is mounted on the frame 115, one end 117 of which, like a funnel, is widened adjacent to the end 77 of the dome in order to receive a rolled-up tube 118 from the mandrel, which tube passes between the flattening rollers 111 and 112 and is delivered folded from these .

In operation, the device 20 automatically holds the top sheet 35 of the stack at a given height, which is controlled by the height sensing switch 51 and the tool table 25. At this given height, the retaining pointed element 71 engages through or in at least the uppermost sheet and the next sheet 25 of the stack. In addition, the uppermost sheet of the stack is located in its regulated height in the vicinity of the mandrel 75 slightly below the underside thereof. If the dome 75 rotates counterclockwise according to FIG. 6 and vacuum is applied to the interior of the mandrel 75 via the line 79, the edge of the uppermost sheet, which is immediately below the mandrel, is raised and applied to the mandrel, as is shown in Fig. 8. The set mandrel rotation serves to wind the top sheet around the mandrel, the top sheet assuming a distance from the next sheet which allows free sliding relative to it, and the top sheet being torn out of its stapled position by the pointed holding elements 71 . The suction applied to the interior of the mandrel 75 can be separated again after a few revolutions of the dome. The roller 107 'is seated on the outermost turn of the sheet being rolled up during the rotation, so that a slight pull is applied and a reliable winding or winding effect is achieved. Each sheet 35 has a register or control mark 120, which is below

a sensor 121 located in the vicinity of the mandrel 75 passes through and acts in such a way that the rotary drive of the mandrel is interrupted, for example, by switching off the motor 85. The register mark 120 and the sensor 121, which can act, for example, photoelectrically, stop the winding rotation of the mandrel 75 in a specific desired angular position with respect to the folding device 110. The sensor 121 therefore ends the mandrel rotation via corresponding conductors 122 and suitable control devices. During the winding process, the friction claws 105 are kept open in the position according to FIG. 8 by the downwardly directed piston rod 108 and the cam component 109. Upon completion of the mandrel rotation, a fluid such as compressed air is used to pull the piston rod 108 and cam member 109 upward, thereby releasing the friction claws 105 to assume their gripping position as shown in FIG. 9 on a sheet 35a wound around the mandrel 75 .

In addition, fluid pressure can be used to move the carriage 94 towards the folding device 110, whereby the tubular rolled sheet 35a is stripped and enters the guide sleeve 116, where it is further pulled and folded by the rollers 111 and 112.

FIG. 10 shows a sheet 35 located outside the device with a plurality of dividing lines 125 which separate the sheet in a plurality of strips 126 extending in the longitudinal direction. A plurality of glue dots 127 are applied along one of the edges of the sheet 35, one on each of the strips 126. The sheet 35 is wound on the mandrel 75 as described, thus taking the form of the spirally wound tubular structure 35a 11. When fully wound, the glue spots 127 serve to hold the outermost turn in place and to keep the wound tubular structure 35a closed. The roller 107 'helps to keep the tubular structure 35a closed as a roller until the glue points 127 bind.

When the wound tubular structure 35a is stripped off and when it is fed through the folding rollers 111 and 112, a flat structure 35b as shown in FIG. 12 or folded as a roll results on the output side. In this form, the structure 35b is transferred to a cutting machine, for example a strip cutting machine and cut along the dividing lines 125, so that a plurality of individual folded windings 35c according to FIG. 13 are produced.

10 The mandrel was shown with a constant, generally circular cross-section over its entire length, but if desired, mandrels of a different cross-sectional shape can also be used, for example mandrels with flattened, flattened, elliptical or polygonal cross-section. If desired, such cross-sections can serve to initiate the folding process; in certain circumstances, even the special folding can be omitted. For example, it may be desirable to produce a coil that is formed as a tube of circular or polygonal cross-section without flattening, for example to be arranged in a package or a container of circular cylindrical or polygonal-prismatic shape.

At the end of the description of the operation, it is further stated that the carriage 94 returns to its initial position shown in FIGS. 5 to 7 and the cylinder 107 is operated again to spread the claws 105, within a given time cycle or by others Control means for repeating the process described.

The invention thus creates a compact folded label holder in particular and specifies a method and a device for producing information-provided reels that are extremely simple and fast, work long and reliably during long operating times, bring considerable cost savings and also in others Fully serve their intended purposes.
