Definitions
- the pressure roller is pressed against the winding tube or the winding roller that is being formed by an drive device in order to obtain a tightly wound winding roller without air inclusions between the individual layers wound on *.
- Devices of the type specified at the outset are known in which the pressure roller is mounted on a carriage which is provided with a drive which moves the pressure roller and presses against the winding tube or the winding roller which is being formed.
- the slide which can be moved in the guides of the machine frame, can only be moved against considerable unavoidable frictional forces, it also forms with the pressure roller considerable masses that have to be moved when moving the carriage.
- this object is achieved in that the pressing roller is mounted on at least one coupling rod which is articulated to two links, the other ends of which are pivotally mounted in the machine frame, and in that the coupling rod or one of the links is provided with a drive device.
- the pressure roller is expediently mounted between two coupling rods, each of which is articulated to two links, the other ends of which are pivotably mounted in the machine frame.
- the coupling rod provided according to the invention with two links forms a four-joint support system which absorbs the weight of the pressure roller in a favorable manner.
- the device according to the invention is thus characterized in that the pressure roller is mounted with low friction between coupling rods of four-articulated systems.
- the pressure roller can be sensitively adjusted by its drive device to the winding tube or the winding roller that is being formed, since no major frictional forces can be overcome. Since the pressure roller is not mounted on a slide, the masses to be moved are reduced. The pressure roller is only moved in the horizontal direction by its drive, so that the influence of the mass on the pressure force is negligible.
- the shorter rear links pivot the coupling bars around the joints on the front links due to their smaller pivoting radius in such a way that the lifting effect of the four Joint system is superimposed on a pivot movement of the coupling rod, so that the pressure roller performs a linear movement when it is moved in the direction of the winding tube or winding roller.
- the handlebars are mounted on a carriage which can be moved in the machine frame.
- the slides are provided with a controlled drive which moves them when the approximate straight line of the system consisting of the handlebars and coupling rods is exhausted.
- FIG. 1 is a side view of the winding device according to the invention with the front side wall of the machine frame removed,
- FIG. 2 the four-articulated pull-out of FIG. 1, each consisting of two links and coupling rod.
- Fig. 3 is a plan view of the exploded four-link system consisting of two links and a coupling rod on one side.
- FIG. 1 shows a rear plate-shaped side part 1 which is part of a machine frame.
- the front side panel is removed to make the devices located between the side panels more visible.
- a slide is guided horizontally. Only the rear side wall 2 of the carriage is also shown, since the front side wall is again removed for reasons of better illustration.
- the side walls 1 of the carriage are connected to one another by cross members, not shown.
- the side walls 2 are guided displaceably in dashed guides 3 of the side parts 1, at their upper side edge at least the side wall 2 is provided with a rack 4 which meshes with the pinion 5 of a geared motor 6, which for moving the slide with the side walls 2 of the electronic machine control is controlled.
- two-armed levers 8 are pivotally mounted on both sides, their arms 10 pointing in the direction of the winding tube 9 carry the charging electrode 12 which extends across the width of the web 11.
- the inner arms 13 of the two-armed lever 8 are provided with axle journals 14, on which rollers 15 are mounted, which are guided in guides 16 of the side parts 1 of the frame consisting of elongated holes.
- the guides 16 consist of a sloping section 17 and a section 18 which adjoins this and runs parallel to the guide 3.
- a linear unit for example a col- benstange ⁇ loser pneumatic cylinder attached, which moves a cutting knife 19 across the width of the web 11 for the purpose of severing the web 11.
- rockers 20 are pivotally mounted on the inner sides of the side walls 2 of the slide and are pivotable by pneumatic cylinders 23, the piston rods 21 of which are pivotably mounted on pins 22 of the rockers 20.
- the cylinders 23 are pivotally mounted on pins 24 of the side walls 2 of the slide.
- the rockers 20 carry 23 journal 30 above the pneumatic cylinder, on which coupling links 31 are mounted.
- the coupling links 31 are articulated at their rear ends in the articulation points 33 with links 32, the upper ends of which are pivotably mounted on the journal 34 of the side walls 2.
- the coupling members 31 protrude beyond the rockers 20 in the direction of the winding tube 9.
- the pressure roller 38 is mounted between the free ends of the coupling rods 31.
- the electrode 12 can consist of a series of needles and is laterally bordered by strips which protectively cover them.
- the arrangement of the knife 19 with the rodless pneumatic cylinder on the support of the electrodes 12 leads to a severing just above the nip between the winding sleeve 9 and the pressure roller 38 when the separating knife is activated, so that a web start with a short flag is formed.
- the web 11 runs in the direction of arrow A and is fed to the pressure roller 38 by a guide roller 39, which can be mounted, for example, between the side walls 2 of the slide.
- the two-armed levers 8 with electrodes 12 and cutting knives 19 and the guides 16 for the rollers 15 of the inner arms of the two-armed levers 8 are arranged in mirror image to a central plane 40 which runs through the axes of the winding sleeve 9 and the pressure roller 38. In this way, a simple changeover of the winding device to left-right winding is possible.
- FIG. 2 shows the four-link system, which is drawn out of FIG. 1 for the purpose of a clearer representation and consists of the links and the coupling rod, for the approximately straight guidance of the pressure roller 38.
- the linkage-forming rockers 20 on each side are attached to or clamped on the pivoting arm 7, which are mounted in the manner shown in FIG. 3 between the side walls 2 of the slide which is displaceable in guides 3 of the side parts 1.
- the links 32 are pivotally mounted on the journal 34, which are firmly connected to the side walls 2 in the manner shown in FIG. 3.
- the coupling members or coupling rods 31 are articulated on the rockers 20 in the joints 30 and on the links 32 in the joints 33.
- the coupling rods 31 project beyond the rockers 20 by sections 40 of a predetermined length, between which the pressure roller 38 is mounted.
- the link 32 is shorter than the rocker 20 between its joints 7 and 30.
- the link 32 starting from its upper bearing 34, is inclined at an acute angle towards the rocker 20.
- the different lengths of the rockers 20 and the link 32 as well as the distances between the joints 30 and 33 on the coupling rods 31 and the lengths of the coupling rod sections 40 between the bearings for the pressure roller 38 and the bearings 30 on the rockers 20 are matched to one another, that when the coupling rods are pivoted between the position of the pressure roller 38 shown in full lines in FIG. 2, in which the coupling rods are displaced in the direction of the winding tube, and the retracted position shown in broken lines, the movement of the pressure rollers takes place approximately linearly in the horizontal direction.
- the rockers 20 protrude down the coupling rods 31 by sections 41 of a predetermined length.
- a bearing pin 22 is provided below the coupling rod 31, on which the piston rod 21 of the pneumatic cylinder 23 is mounted, which in turn is pivotably mounted on the pin 24, which is firmly connected to the side wall 2.
- the tension springs 25 are tensioned between the pins 26 of the sections 41 of the rockers 20 and the pins 27 provided on the side walls 2, which serve to enlarge the adjustment range of the contact pressure exerted by the pneumatic cylinders 23 on the rockers 20 becomes.
