Definitions

  • the invention relates to a folder for processing a plurality of, preferably two webs running in side by side with at least one paddle wheel, which has a plurality of compartments on the circumference delimited by lateral guide disks.
  • two webs running in side by side can be cut to length and processed independently of one another, whereby different types of production can be carried out.
  • the paddle wheel extending over the entire working width of the folder is undivided and accordingly has the same circumferential speed over its entire length.
  • paddle wheel is subdivided into a number of laterally adjoining paddle wheel sections which can be driven independently of one another and which corresponds to the number of webs which can be processed next to one another.
  • each section of the paddle wheel can always be driven at a speed which is adapted to the respective type of production, such that in the area of each section each compartment is occupied with a product on the circumference.
  • the scale streams formed on the delivery belt under the paddle wheel are accordingly formed with the same product distance, which not only results in good accuracy, but at the same time also reduces the difference in the scale distance.
  • Another advantage of the measures according to the invention can be seen in the fact that the individual sections of the impeller are adjustable in the circumferential direction independently of one another. The circumference of the individual sections of the paddle wheel can therefore be adapted exactly to the weight of the respective products.
  • the measures according to the invention offer the possibility, in the case of processing fewer webs than the maximum number of webs, to shut down the blade wheel section that is not required in each case.
  • the laterally adjoining vane wheel sections can have coaxial shaft pieces which are supported on one another in the abutment area and which are provided with drive devices in the region of the opposite ends which are supported in the folder side walls.
  • This configuration results in a very compact structure with a continuous, only subdivided, central shaft. It is therefore possible, despite the subdivision of the paddle wheel, to also be able to readily accommodate the products which are produced from closely adjacent paths and accordingly have no significant distance.
  • One of the shaft pieces can expediently have a coaxial bore and the other one can have a journal mounted in it. This ensures that no mutual spacing of the shaft pieces arranged next to one another is caused by the mutual mounting.
  • the lateral drive devices each have a plurality of drive wheels of different diameters which are connected in a rotationally locking manner to the associated shaft piece and which cooperate with assigned output wheels of a manual transmission which can optionally be coupled with this input wheel.
  • This measure facilitates the quick setting of the correct speed and results therefore a high level of user-friendliness.
  • the input wheels of the two manual transmissions can be driven by means of a shaft running across the width of the folder, which is particularly simple in construction and, in the case of the same types of production, in the processing of all webs or in the processing of a web spanning the entire working width, a synchronization of the adjacent ones Paddle wheel sections relieved.
  • the drive wheels can be received on a carrier comprising the assigned shaft piece, which is coupled via a helical toothing with a bushing which is axially displaceable and wedged onto the assigned shaft piece.
  • a carrier comprising the assigned shaft piece, which is coupled via a helical toothing with a bushing which is axially displaceable and wedged onto the assigned shaft piece.
  • a further expedient measure can consist in that the compartments of the impeller sections arranged next to one another are separated from one another by at least one guide disc, and in the region of the outer ends of the impeller also guide discs are provided. These guide discs result in an exact alignment of the products entering the compartments and ensure that the products manufactured next to one another do not interfere with each other.
  • each shaft piece can have a disk carrier arranged in the joint area, on which a guide disk that is divided on the circumference can be detachably fixed, at least up to in the radial direction extends into the area of the compartment.
  • the annular guide disks received on the circumference of these disk carriers can be easily removed due to their distribution. It is therefore readily possible to remove one or both guide disks, provided that closely adjacent paths or a path that spans several blade wheel sections are processed.
  • the disc carrier and accordingly the guide discs are expediently laterally adjustable, so that the distance and the width of the webs to be processed can be taken into account.
  • the folding apparatus on which FIG. 1 is based has a working width such that two webs 1, 2 of normal width running side by side or a double-wide web can be processed into folded products.
  • NEN in the form of a number of shingled streams corresponding to the number of incoming webs, here in the form of two shingled streams 3, 4, are deposited on a paddle wheel 5 which extends under the entire working width of the folding apparatus 5 and extends under a delivery belt 6.
  • the working elements of the folder are designed so that different types of production are possible over the working width. For example, it is possible to run collective production in the area of one side of the folder and non-collective production in the area of the other side.
  • the paddle wheel 5 provided with circumferential compartments 7 is divided into two sections 5 a, b adjoining one another in the axial direction in accordance with the number of two tracks 1, 2 fed here.
  • the butt joint of the mutually aligned, laterally adjoining sections 5 a, b is located in the center of the folder in accordance with the web guide.
  • the two sections 5 a, b are mounted so that they can rotate independently of one another and can accordingly be driven independently of one another.
  • Each section of the Paddle wheel 5 is driven at a speed adapted to the type of production being driven on the side in question so that each of the peripheral compartments 7 of each section 5 a, b is occupied with a product.
  • the paddle wheel sections 5 a, b are accordingly assigned separate drive devices 9, which are arranged here in the region of the outer sides of the folder side walls 8 facing away from one another.
  • the paddle wheel 5 divided here in the center of the folder consists, as can best be seen from FIG. 2, of two shaft pieces 10, 11 arranged coaxially next to one another, which are mounted in the area of their ends facing away from one another in the folder side walls 8 and with their ends facing one another.
  • the superimposed, aligned shaft pieces 10, 11 practically result in a central support which is continuous over the entire width of the folder and has sections which can be rotated independently of one another.
  • the one shaft piece 11 is provided with a blind bore 12 arranged coaxially to the axis, into which a pin 13 of the other shaft piece 10 projecting over the butt joint engages.
  • vane carriers 14 which run in a rim shape and are wedged onto the shaft pieces 10, 11 forming a central carrier, which are covered on the circumference with the front and rear boundaries of the compartments 7 forming blades 15.
  • the number of spaced-apart blade carriers 14 depends on the width of the webs 1, 2 to be processed in each case.
  • the web 1 and the folding products 1a produced therefrom are narrower than the web 2 and the folding products 2a produced therefrom. Accordingly, wider compartments with more blades are provided in the area of the blade wheel section assigned to the track 2 than in the area of the other blade wheel section.
  • the blade carrier 14 which is not required here in each case can be removed.
  • the products 1 a and 2 a are guided laterally when inserted into the compartments 7 of the respectively assigned paddle wheel section.
  • the compartments laterally delimiting, ring-shaped, inner and outer guide disks 16 and 17 are provided. These are accommodated on disk carriers 18 and 19, which are laterally slidably slidable on the associated shaft pieces 10 and 11 and encompass the shaft pieces.
  • the guide disks 16, 17 and accordingly the disk carriers 18, 19 carrying them can be arranged immovably in the axial direction.
  • the disk carriers 18, 19 are used to adapt the compartments which are laterally delimited by the guide disks 16, 17 accommodated on them to the respective web widths and positions on the each associated shaft pieces 10, 11 colliding in the area of the folder center are laterally adjustable.
  • the width is adjusted primarily by adjusting the outer guide disks 17.
  • the associated disk supports 19 can accordingly be shifted from the outermost position for the wider track 2 shown on the left in FIG. 2 to the innermost position for the narrower track 1 indicated on the right in FIG vice versa.
  • the inner guide disks 16 correspond to the web distance.
  • actuating devices acting on the associated disk carriers 18 and 19 are provided.
  • the disk carriers 18, 19 are provided with a circumferential groove 20 in a hub-shaped region comprising the associated shaft piece 10 or 11, into which a driver accommodated on a radial actuating arm 21 engages. As can best be seen from FIG. 3, this is best designed as a fork 21 a.
  • the radial actuating arms 21, which engage the outer guide disks 17 and hold the outer guide disks 17 outside the guide disks 17, can be moved by means of an associated, parallel shaft rack 22, which interacts with a drive pinion 23.
  • the toothed racks 22 can be guided in recesses in the folder side walls 8.
  • the adjusting arms 21 assigned to the inner guide disks 16, which can be adjusted only slightly, are adjustable by means of adjusting spindles 24 which are parallel to the shaft and which are fastened to the side walls 8 of the folder Traverse 25 can be added.
  • the actuating arms 21 are also provided with bushes 26 mounted on the crossmember 25, which results in good stability despite the greater length of these actuating arms, which have to be led out over the circumference of the paddle wheel.
  • the cross member 25 is positioned in a peripheral region of the paddle wheel 5, in which the compartments 7 are empty, so that the insertion or ejection of the products is not hindered by the actuating arms 21, which are guided over the paddle wheel circumference and assigned to the inner guide disks 16.
  • the disk carriers 18 and 19 are provided with relatively long hub bodies that encompass them and are provided on the associated shaft pieces 10, 11 in order to achieve reliable guidance.
  • a blade carrier 14 is received on the hub body of the inner disc carriers 18, so that there is a relatively small distance between the inner blades 15 and the adjacent inner guide discs 16.
  • the disk carriers 19 assigned to the outer guide disks 17 protrude beyond the guide disks 17 so that they can be placed close enough to a blade carrier 14 accommodated on the associated shaft piece 10 or 11.
  • the outer guide disks 17 are molded onto the associated, hub-shaped disk carriers 18.
  • the inner guide disks 16 consist of the associated ones Disc carriers 18 releasably receivable segments 16 a. These are provided in the region of their radially inner edge with a widening 27 forming a foot, which can be attached to the periphery of the approximately equally wide disk carrier 18 and can be screwed to it with screws 28. These are captive.
  • the radially arranged screws 28 engage with their heads in a radial recess 29 provided in the area of the assigned segment 16a, the radial length of which is shorter than the screw length.
  • the fact that the inner guide disks 16 can be removed enables the inner compartment boundary to be adapted to any web distance or the production of compartments which are continuous over the entire width of the impeller.
  • the inner disk carriers 18 accommodated on both shaft pieces 10, 11 are equipped with a guide disk 16, as is indicated in the upper half of the paddle wheel on which FIG. 2 is based.
  • the pane supports 18 are in a position approximately symmetrical to the butt joint. If the webs to be processed next to one another have no significant distance, only one of the two inner disk carriers 18 is fitted with an annular guide disk 16a consisting of segments, as indicated in FIG. 2 below. This one guide disk 16 a is positioned exactly in the middle, ie exactly in the area of the butt joint, which is achieved by appropriate lateral adjustment of the disk carrier 18 can be accomplished.
  • the radially outer edge of the guide disk 16 is tapered outwards to form contact surfaces 30 for the products entering the impeller.
  • the unoccupied pane carrier 18 still ends radially within the compartment floor and therefore does not interfere. If a double-width web is processed instead of two webs running side by side, all inner guide disks 16 are removed, so that undivided compartments result over the entire width of the impeller. In this case, the two blade wheel sections 5a, b are driven synchronously and thus act like an undivided blade wheel.
  • the side drive devices 9 assigned to the shaft pieces 10, 11 each contain, as can further be seen in FIG. 2, a set of wheels with a plurality of drive wheels 31 a, b, c of different diameters connected to the assigned shaft piece 10, 11.
  • a gearbox 32 with output wheels 33 a, b, c meshing with drive wheels 31, a, b, c is assigned to the set of wheels comprising drive wheels 31 a, b, c, and can optionally be coupled to an input wheel 34.
  • the manual transmission 32 is provided with a coupling element arranged coaxially to the wheels and axially adjustable by means of a handle 35.
  • the output wheel 33 a or b or c coupled by this coupling element to the input wheel 34 is driven.
  • the other output wheels run due to their engagement in the associated drive wheel of the shaft set of wheels empty with.
  • the input wheels 34 of the two side gearboxes 32 are driven uniformly by drive pinions 37 which are received on a drive shaft 36 which extends over the machine width.
  • the sections 5 a, b of the paddle wheel arranged next to one another can be adjusted forwards or backwards in the direction of rotation in order to regulate their circumferential position depending on the weight of the folded products to be picked up.
  • the drive wheels 31 a, b, c are received on a carrier 38 comprising the associated shaft piece, which is toothed via a helical toothing 39 with a bush 40, which is keyed onto the assigned shaft piece 10, 11 and by means of an adjusting spindle 41 engaging on it axial direction is adjustable.
  • Boxes 42 are provided on the folder side walls to accommodate the drive devices 9.
