Abstract

The frame (1) contains a glue-applicator roller (5) rotarily driven on a center lengthwise axle (8), and a pressure roller (10) rotarily driven on a center lengthwise axle (11). A corrugated cardboard web (47) consisting of at least one covering web (50) and corrugated web (49) travels through the gap (53) between the glue-applicator and pressure rollers. A dynamometer (34) measures the actual force in the gap at right angles to the web. The height of the gap can be altered by an adjustment (36), and a regulator (43) compares the actual and nominal forces in the gap.

Description

The invention relates to a method for controlling the height of a nip between a glue application roller and a pressure roller a gluing device for a corrugated web according to the general Genus of claim 1 and a gluing device for Execution of the method according to the general genus of the claim 4th

If there is a corrugated cardboard lined on one side with a cover sheet their other, not yet laminated side with another deck sheet to be laminated, the tips of the corrugated web must first be used be glued on the not yet laminated side. The one-sided laminated Corrugated cardboard web is for this purpose through the nip of a gluing device, a so-called gluing unit. Here it is extraordinary difficult to adjust the height of the nip so that on the one hand the hydrodynamic pressure of the glue film on the glue application roller is overcome, i.e. gluing the tips of the corrugated web takes place, on the other hand, but not by setting the height too small of the nip crushed the corrugated web and over-gluing it Peaks.

The invention is therefore based on the object of a method of general Genus of claim 1 and a gluing device to create general genus of claim 3, by means of which an optimal Gluing the tips of the corrugated sheet to one that is already laminated on one side Corrugated cardboard sheeting.

This object is achieved according to the invention by a method with the features of claim 1 and by a gluing device with the Features of claim 4 solved. The for optimal gluing of the The actual force required in the nip is correlated empirically determined.

Advantageous and partly inventive further developments result from the subclaims.

Further features, advantages and details of the invention result from the following description of an exemplary embodiment with reference to the drawing. It shows:

Fig. 1
a vertical longitudinal section through a gluing device according to the invention and
Fig. 2
a vertical cross section through the gluing device according to FIG. 1st

The gluing device shown in the drawing has a frame 1, which consists essentially of two side walls 2, 3, the are connected to each other by means of cross struts 4. In the side walls 2, 3, a glue application roller 5 is rotatably supported by bearings 6 which by an electric drive motor 7 about its horizontal central longitudinal axis 8 is drivable. The drive motor 7 is on the side wall 2 supported. Below the glue application roller 5 is a glue tub 9 arranged, in which the application roller 5 dips.

A pressure roller 10 is arranged above the application roller 5, whose central longitudinal axis 11 runs essentially parallel to the axis 8. The pressure roller 10 is by means of bearings 12 in bearing levers 13, 14th freely rotatable. These bearing levers 13, 14 are in turn by means of lever bearings 15 on the side walls 2, 3 about a common pivot axis 16 freely pivoted. The pivot axis 16 also extends parallel to the axes 8, 11. The pivot axis 16 is located in the Near one - in Fig. 1 left - end 17 of the levers 13, 14, while the Pressure roller 10 at a distance from it in the vicinity of the other - in Fig. 1st right - end 18 of the lever 13, 14 is mounted.

Attacks in the vicinity of the ends 18 assigned to the pressure roller 10 a pressure drive 19, 20 on each lever 13, 14, which is actuated by a fluidic, in particular pneumatically actuated piston-cylinder 21 is formed. Each cylinder 21 of the drives 19, 20 is a common, pivot axis 22 parallel to axes 8, 11, 16 is pivotable on the side wall 2 or 3 articulated. The piston rod attached to the piston 23 24 is on the respective lever 13 or 14 by a likewise to the axes 8, 11, 16, 22 parallel pivot axis 25 pivotally articulated. The drives 19, 20 can be acted on from both sides, i.e. on both sides of the piston 23 fluid lines 26, 27 open into the respective cylinders 21. The lines 26, 27 are connected to a solenoid valve 28, the one of a Pressure fluid source 29 Pressure fluid can be supplied at constant pressure can. The lines 26, 27 also open out of the valve 28 assigned return lines 30, 31.

Between each lever 13, 14 and the frame 1 there is a pressing force setting device 32, 33 arranged. This each has a force measuring device 34, for example a so-called load cell, which over a support plate 35 opposite the respective side wall 2 or 3 is supported in a stationary manner. The force measuring device 34 is in turn supported via a distance adjusting device 36 relative to the respective Lever 13, 14 off. This adjusting device 36 has two wedges 37, 38, of which the one - upper - wedge 38 according to the directional arrow 39 compared to the other - lower - wedge 37 adjustable is. The wedge 38 is adjusted by means of an adjustment drive 40, which is designed for example as a spindle drive. The sliding one Wedge 38 is via a thrust bearing 41 opposite the respective lever 13 or 14 supported. The lower wedge 37 is in the direction of the direction arrow 39 immovable. A vertical displacement to the force measuring device 34 out is not necessary since such measuring devices work almost path-free.

The force measuring device 34 is connected to a control device via a signal line 42 43 connected, which in turn with a corresponding Control line 44 is connected to the adjustment drive 40. Still is a control device 45 is provided, which by means of a control line 46 is connected to the solenoid valve 28.

The gluing device creates a one-sided corrugated cardboard web 47 guided in the transport direction 48. The corrugated cardboard web 47 thus exists of a corrugated sheet 49 and a cover sheet 50. The corrugated sheet 47 is when entering the device with its corrugated web 49 via a Deflection roller 51 and then with its cover sheet 50 over a plain strip roller 52 led. Then it passes through the nip 53 performed between the application roller 5 and the pressure roller 10, wherein provide the bottom 54 of the corrugated sheet 49 with glue 55 be from the glue application roller 5 from the glue tub 9 in Form of a thin film on the glue application roller 5 is fed. The rollers 5, 10 rotate in the nip 53 in the transport direction 48, thus in the directions of rotation 56 and 57.

The setting of the height a of the nip 53 and its regulation takes place in such a way that from the rollers 5, 10 on the corrugated web 47 applied force kept at a constant predetermined value becomes.

For this purpose, the pressure drives 19 and 20 from the pressure fluid source 29 applied with a constant pressure so that it with a act constant force on the respective lever 13 or 14. This Forces and resulting from the weight of the levers 13, 14, the pressure roller 10 and the resulting forces on the levers 13, 14 are overall constant. These forces work downwards. Facing you act forces, on the one hand in the nip 53 and on the other on the pressing force adjusting devices 32, 33 in the opposite direction attack above. The sum of these forces is also constant. The the actual force exerted on the corrugated cardboard web 47 hangs in the nip 53 that is, from those occurring in the pressing force setting devices 32, 33 Forces. When the in the nip 53 on the corrugated web 47th exerted pressing force is to be increased, then must accordingly the forces acting in the devices 32, 33 are reduced and vice versa.

Each force measuring device 34 detects the force measuring device 34 in the device 32 or 33 actual force acting continuously via the signal line 42 given to the control device 43 and the sum there with a previously set target force compared. The setting of this target force can also correspond to the force exerted in the nip 53 on the corrugated web 47 should act. Because for the reasons mentioned the sum of these Forces and the forces acting in the devices 32, 33 is constant, a corresponding conversion can be carried out in the control device 43. When the sum of those measured in each force measuring device 34 Actual forces is greater than the previously set target force, then is called this is because the actual force acting in the nip 53 has become too small, that its height a has become too great. In this case everyone will Adjustment drive 40 a control signal for shifting the associated Given wedge 37 in the direction that the height a of the nip 53rd is reduced, namely until the measured in the devices 32, 33 Actual forces, and thus indirectly also those acting in the nip 53 Force, again correspond to the previously set target value.

If, on the other hand, the sum of those measured in each force measuring device 34 Actual forces becomes smaller than the previously set target force, then this means that the actual force acting in the nip 53 has become too great is that its height a has become too small. In this case, is on each adjustment drive 40 has a control signal for shifting the associated one Given wedge 37 in the direction that the height a of the nip 53 is increased, and that until the devices 32, 33 measured actual forces and thus indirectly also those in the nip 53 acting force, again correspond to the previously set target value.

The control device 43 and the control device 45 can in the Be linked together in such a way that for the control device 45 Start of a gluing process a base height a for the corrugated cardboard web 47 is entered so that the adjustment process does not take too long.

Otherwise, the pressure roller 19 is also the pressure roller 10 lifted up.

The corrugated cardboard web 47 glued in the gluing device is shown in FIG Usually supplied to a known laminating device in which against the glued tips 54 of the corrugated sheet 49 another cover sheet is created.

Instead of the embodiment described above, the regulation of the Force in the nip 53 and thus the control of the height a of the nip 53 take place over its entire length in such a way that the of the two force measuring devices 34 of the pressing force setting devices 32, 33 measured forces are not added up and then in the described further treatment, but that they are individually with half the value of the target force in the nip 53 are compared and that then a corresponding individual control of the distance adjusting devices 36 of the pressing force adjusting devices 32 or 33. In this way, a non-parallel adjustment of the Rolls 5 and 10 occur towards each other, i.e. the nip 53 may have not the same height over the full length; hereby can different thicknesses of the corrugated cardboard web 47 compensated for their width be, so that even over the width of the corrugated web 47 no low pressing forces or excessive pressing forces can occur.
