Definitions

  • the invention relates to a device for applying an adhesive to a web, consisting of a rotating, hollow application cylinder with a plurality of outlet openings located in its cylinder wall, which are arranged in at least one row along a surface line of the application cylinder and through which the Inner space of the application cylinder is conveyed from a storage container via a stationary axial adhesive connection to the face of the adhesive that can be supplied on the face and onto the web that wraps around its outer circumference in a partial area.
  • Such a device is known from DE-B-1 047 968, the aim of which is to apply pressure-sensitive adhesive tapes, such as. B. to produce plasters.
  • the rotating application cylinder is completely filled with the adhesive under pressure, the pressure being supposed to be just high enough to overcome the friction in the feed lines and in the relatively large outlet openings.
  • the application of adhesive to the web to be coated is to be brought about by generating a negative pressure on the back of the web, which necessitates the use of air-permeable webs.
  • the aim of the invention is to create a cross-gluing unit for very fast-moving webs, in particular for the bonding of several webs in rotary printing presses.
  • very fast moving webs is understood to mean those with a continuously variable feed speed of several hundred meters / minute, for example 300 to 500 m / min.
  • the invention is based on the task, a transverse glue applicator! ' to develop very fast-running webs or blanks, which is able to apply regardless of the changing overall schwindigke i th position and exact contours Beleimitch at predetermined locations, without the risk of Wegspritzens of the adhesive.
  • the outlet openings are designed as capillary openings, whereby the Connected to the inside of the individual outlet openings is an adhesive feed channel that faces away from the central axis of the application cylinder and extends parallel to the surface line of the application cylinder, which is connected to the axial adhesive connection, and that control is provided to prevent the flow through the capillary openings during the cover-free circulation phase and the circumference of the application cylinder corresponds to the desired distance between the cross-glues or a whole multiple of this distance.
  • the individual outlet opening is preferably designed as a bore (throttle nozzle) of such a diameter that the centrifugal force of the adhesive is only slightly greater than the opposing forces, even at high speeds of the application cylinder. It has proven to be beneficial. proven if the outlet opening behind an approximately 1 mm long bore outlet of approximately 0.8 mm diameter has a bore constriction of approximately 2 to 4 mm in length with a diameter of approximately 0.3 mm.
  • the invention initially avoided applying the adhesive from the cavity of a rotating cylinder. This is because the larger the filling quantity of the cylinder, the larger the surface of the adhesive mass and the more easily the adhesive tends to form skin. Instead, the cylinder has the subject of Invention more a carrying function. This is because the adhesive is fed through a tube (adhesive feed channel) which extends peripherally of the application cylinder along a surface line to the outlet openings in the form of bores or throttle nozzles. (Continued on page 4 of the original version).
  • the adhesive application is based on the centrifugal force of the adhesive located in the outlet openings, which essentially counteracts the viscosity, the throttling effect (capillary effect) and the external pressure. It is now important to choose the cross sections of the outlet openings so that the adhesive cannot spray out of the outlet openings even at high rotational speeds. Since the application cylinder is wrapped in a not inconsiderable part of its circumference by the web to be coated, the web has a covering effect in this area and prevents the adhesive from flowing out. There is only a kind of beading out of the adhesive from the outlet openings.
  • the outlet openings can be covered on the inside in a controlled manner by a closure element.
  • This closure element opens the access to the capillary openings as soon as the row of holes is covered by the web to be coated. Accordingly, the closure takes place in good time before the web leaves the jacket area of the application cylinder again.
  • the closure element expediently passes through the adhesive feed channel and is driven in an oscillating or rotary manner.
  • the closure element is designed as a strip-shaped sealing lip which can be adjusted against the inside of the outlet openings and is arranged radially at the top on a control shaft which passes through the adhesive feed channel with play and is rotatably mounted on the application cylinder.
  • both the adhesive feed channel and the control shaft can be arranged in an insert, for example in a hollow bar, which can be inserted into a suitable recess in the application cylinder.
  • the control shaft is provided with a gearwheel which rolls directly or indirectly on a stationary gearwheel arranged concentrically to the axis of the application cylinder.
  • the control shaft makes the same rotation as the application cylinder, the control shaft also being able to rotate in the opposite direction to the application cylinder.
  • the closure element is designed so that in the area where the row of holes is covered by the web to be coated, the outlet openings are connected to the feed channel and can release adhesive.
  • the invention provides in a further embodiment that the order cylinder is provided or connected with a speed-dependent or consumption-dependent metering arrangement for changing the filling quantity of the adhesive feed channel.
  • a speed-dependent or consumption-dependent metering arrangement for changing the filling quantity of the adhesive feed channel.
  • This valve has the effect of temporarily separating the adhesive located in the adhesive feed channel and in the outlet openings from the adhesive flowing in, in order in this way to reduce the centrifugal forces. In this case, it is advisable to provide ventilation arrangements in the area of the feed channel in order to facilitate the outflow of the adhesive from the bores.
  • a throttle in the feed area of the adhesive which can also be adjustable depending on the speed of its cross section.
  • the invention provides the possibility of providing a negative or positive pressure control for the adhesive to be conveyed into the adhesive feed channel as a metering arrangement.
  • the intention is to increase or decrease the pressure in the outlet openings caused by the centrifugal force. It has even been found that it is not necessary to cover the outlet openings on the inside with such controls. On the other hand, a narrowing of these outlet openings can be dispensed with when covering the outlet openings on the inside.
  • a rotating application cylinder 4 is used to apply the cross-gluing 17, the circumference of which corresponds exactly to the predetermined distance between the cross-gluing 17. This applies when the application cylinder 4 has a single row of bores 7 through which the adhesive exits under the effect of centrifugal force. However, it is also possible for the application cylinder 4 to contain two or more such rows 7 of holes which are at the same distance from one another. Then the circumference of the application cylinder 4 is a whole multiple of the distance between the cross-glues 17.
  • the web 2 to be coated is guided with the aid of the deflection roller 3 so that the application cylinder 4 is wrapped in the web 2 in a not inconsiderable part of its circumference. In the area of this wrapping, the row of holes 7 is accordingly covered by the web 2.
  • the other web 14 is guided in the usual way over the guide rollers 15 and can be changed by means of the register roller 16 in such a way that a registration accuracy of certain points of the webs 2, 14 can be set. So that the peripheral speeds of the pull rollers 1 and the application cylinder 4 are constant, the application cylinder 4 is driven by the pull roller 1 via the gear 5 in connection with a correspondingly dimensioned driven wheel 6.
  • the adhesive to be applied is located in a stationary collecting container 12 and arrives via the adhesive line 11 to a stationary adhesive connection 10, from where the adhesive is supplied to a radial connecting channel 9 via an axial bore 30 in the cylinder shaft 28 (see FIG. 4). which opens into an adhesive feed channel 8, from which the row of holes 7 extends.
  • the centrifugal force of the adhesive is counteracted by various forces, one of the most important of which is the capillary force in the outlet openings of the row of holes 7.
  • the outlet openings 18 are designed as simple bores with a diameter of approximately 0.8 mm without narrowing.
  • the individual outlet opening 18 is designed as a throttle nozzle which, starting from the adhesive feed channel 8, has a bore constriction 20. which expands again into a bore outlet 19.
  • the adhesive feed channel 8 is located in an exchangeable insert 21, which is inserted in a corresponding recess in the application cylinder 4 and above the radial one Connection channel 9 is supplied with adhesive. It has proven to be advantageous to design the bore outlet 19 to be approximately 1 mm long and with a diameter of approximately 0.8 mm, whereas the bore constriction 20 can be, for example, 2 mm to 4 mm long and a diameter of only approximately 0.3 mm having.
  • the constriction 20 counteracts the centrifugal force of the adhesive located in the constriction 20 when the application cylinder 4 rotates.
  • the throttle nozzle ' is covered on the outside by the web 2. This means that the adhesive can only bubble out slowly. Even if the outlet opening 18 is not covered by the web 2, the rotation of the application cylinder 4 does not result in the adhesive being thrown off. It is only advisable to cover the outlet openings 18 from the outside during longer breaks in work. For this reason, the covering device 13 is provided in FIG. When work is interrupted, the application cylinder 4 is uncoupled from its drive 5, 6 and brought into a position in which the row of holes 7 is opposite the covering device 13. It is sufficient to prevent air from entering the outlet openings 18 from the outside.
  • the position of the cover device 13 can be changed due to the design. It can also be provided with a lifting or swiveling drive, not shown.
  • the adhesive is preferably supplied from the collecting container 12 to the application cylinder 4 under pressure, so that if the cover 13 is disregarded, the adhesive could gradually exude.
  • the application cylinder 4 is first brought back into its original position in order to bring about the registration accuracy of the cross-gluing 17 with respect to the position of the webs 2, 14.
  • FIG. 3 being an enlarged partial cross section of the application container 4 along the line III-III in FIG.
  • the blinding channel 9 opens into an adhesive feed channel 8, which extends along a surface line of the application cylinder 4 and, in the example of FIG. 3, is formed by a hollow insert 21, the hollow strip 22 of which is closed on the inside by a cover 23.
  • This arrangement 22, 23 is firmly inserted into a corresponding recess in the application cylinder 4, but is interchangeable.
  • a control shaft 24 extending longitudinally therein is arranged and rotatably supported. This carries on its periphery a closure element 25 in the form of a strip-shaped sealing lip which is set against the inside of the outlet openings 18. It is advisable to provide the control shaft 24 with an adjustable bearing so that the required sealing effect is brought about.
  • the sealing lip (closure element) 25 can also be guided in a radially movable manner on the control shaft 24 and pressed on with springs. Between the control shaft 24 and the corresponding bore of the feed channel 8 there is a play 26, through which the adhesive can pass from the feed channel 8 to the outlet openings 18 when the closure element 25 has opened the outlet openings 18 by rotating the control shafts 24.
  • a cylinder shaft 28 is rotatably supported in bearing plates 27 via bearings 52, which supports the jacket of the cylinder via flanges 29.
  • the axial bore 30 opens into the fixed adhesive connection 10, specifically in its hollow shaft 53, which is mounted with the aid of the bearing 31 and is sealed via the seals 32.
  • the hollow shaft 53 of the adhesive connection 10 is connected to the cylinder shaft 28.
  • the screw connection 10 can be easily replaced by a screw connection, not shown.

  • On the control shaft 24 is a rocker arm 36, which is provided with a cam roller 39 and is loaded by a spring 40.
  • This cam roller 39 rotates with the rocker arm 36 about the axis of the application cylinder (4) and rolls on a fixed cam 37.
  • FIG. 4 shows that this cam plate 37 is connected in a fixed manner to the end shield 27 via a connecting sleeve 38.
