Definitions

  • the invention relates to a device for applying a flowable substance, in particular a flowable adhesive, to at least one substrate, with an application nozzle designed as a slot nozzle, which has a stationary nozzle body with an inlet opening, a flow channel and a nozzle slot, wherein when the flowable substance is conveyed the flowable substance passes through the application nozzle from the inlet opening into the flow channel and from this to the nozzle slot and is output through an outlet opening of the nozzle slot, the outlet opening being arranged in an outer region of the nozzle body, the application nozzle furthermore having a slide which, relative to the The nozzle body is movable in the longitudinal extent of the outlet opening via this by means of an adjusting means and makes contact with the outer area for the variable covering of the outlet opening.
  • a cross-sectional area of the flow channel runs in the Y-direction, the cross-sectional area being defined by a plane in the XZ-direction, a width of the nozzle slot runs in the Y-direction, the width in X direction is defined, a depth of the nozzle slot extends in the Y direction, the depth being defined in the Z direction.
  • Devices of the type mentioned are used in different ways.
  • the application of flowable adhesives by means of the devices is regarded as the main area of application.
  • Another important field of application, in contrast to adhesive technology, is coating technology, i.e. the application of flowable substances for the purpose of coating substrates by means of the device.
  • printed sheets are gathered into loose book blocks and then essentially processed on the spine in an adhesive binding device, then glue is applied to the spine of the book block and / or the inside of the spine Cover is applied, which is united with the book block and then pressed against it.
  • the book blocks are each clamped during processing in a guided, circumferential transport clamp of the adhesive binding device with the back protruding downwards.
  • the adhesive is in particular a dispersion adhesive, hot melt adhesive or dispersion / hot melt adhesive combinations.
  • the adhesive polyurethane, or PUR for short has proven to be a hot-melt adhesive, which has particularly good sheet tear resistance and has achieved particularly advantageous results in the book block with regard to the 180 ° opening behavior, the so-called lay-flat behavior.
  • This adhesive can also be used advantageously for poorer paper quality, for example for coated papers in which the proportion of coating components outweighs the fiber proportion required for strength, and which are also more difficult to roughen in order to expose the fiber for bonding.
  • the adhesive is liquefied in a sealed premelting device filled with a dry gas and fed by means of a volumetrically conveying pump via an adhesive feed line to an application head of the application nozzle designed as a slot nozzle and transferred from this to the book block spine or the cover.
  • the amount of adhesive to be conveyed per unit of time depends on the conveying speed of the book block, the book block thickness and the attainable thickness of the adhesive film to be applied to the book block spine or the cover.
  • a control device calculates the required speed of the pump or the amount of adhesive to be conveyed by the pump. In the area between consecutive book blocks, the supply of glue to the slot nozzle must be interrupted.
  • a device having the features of the preamble of claim 1 is from DE 103 20 515 A1 famous. This is used to apply a flowable adhesive.
  • a negative pressure is generated in an adhesive-filled chamber in that a bellows, which is part of a chamber wall, is pulled outwards by means of an adjusting device. The vacuum draws glue into the chamber.
  • An overpressure is then generated in the chamber in that the bellows is pressed into the chamber by the adjusting device.
  • the overpressure causes the adhesive to be pressed out of the chamber through a surface application nozzle and thus applied.
  • the nozzle opening of the surface application nozzle is designed as a slot opening. In relation to its exit cross-section, the slot has a maximum length which corresponds to the maximum width of the book spine to be processed.
  • the nozzle slot is closed tightly using a slide according to the desired width of the book spine.
  • partial areas in particular partial areas of the bellows, have hardly any or little flow of adhesive through them. In these spaces, the adhesive can age and harden completely or partially.
  • the design of the device with the bellows is structurally complex and prone to failure.
  • a device for applying adhesive to a book block spine by means of an application nozzle is known.
  • the application nozzle is wired to an adhesive supply system.
  • An outlet opening of a nozzle slot of the application nozzle can be changed and adapted to the thickness of a book block to be processed.
  • the application nozzle has a first chamber for providing adhesive, adjacent to the outlet opening, and a second chamber, arranged between the outlet opening and the adhesive supply system.
  • a first slide in the area of the first chamber is used to change the width of the first chamber and a second slide in the area of the second chamber is used to change the volume of the second chamber.
  • the second chamber thus represents a reservoir with a variable volume, which can be used to hold excess adhesive when switching from a book block of greater thickness to a book block of lesser thickness or to dispense additional adhesive when moving from a book block of lesser thickness a book block of greater thickness is rearranged.
  • This ensures that excess adhesive does not cause a bead of adhesive when the outlet opening of the nozzle slot is changed, which could either stick the application nozzle or contaminate the book block.
  • the disadvantage of this device is that there are areas in the application nozzle through which there is little or no flow, so that in these cavities, in particular, PUR adhesive can age and fully or partially harden. Apart from this, this device is structurally quite complex.
  • An application nozzle for producing a flat extrudate from liquid material in which a flow channel formed in the nozzle body is in the shape of a clothes hanger is formed is from the EP 0 589 987 A1 famous.
  • an inlet opening into the flow channel is arranged in a central area of the flow channel.
  • the object of the present invention is to develop a device that has the features of the preamble of claim 1 so that it is structurally particularly simple, a uniform exit of the flowable substance through the exit opening is ensured with different cover positions of the slide, as well as with By changing the position of the cover of the outlet opening, no flowable substance emerges from the outlet opening, furthermore no cavities are formed in the nozzle body which are not or only partially filled with the flowable substance.
  • the longitudinal extent of the flow channel is at least as great as the longitudinal extent of the nozzle slot.
  • the inlet opening is operatively connected to the flow channel in the region of one end thereof.
  • the other end of the flow channel ends in the area of one end of the nozzle slot.
  • the outlet opening can be masked by means of the slide from the other end of the nozzle slot.
  • the cross-sectional area of the flow channel in the Y direction steadily decreases from one end of the flow channel to the other end of the flow channel, furthermore the width of the nozzle slot is constant over its course in the Y direction or the width of the nozzle slot increases over its course in the Y direction from the other end to the one end, furthermore the depth of the nozzle slot is constant over its course in the Y direction or the depth of the nozzle slot increases over its course in the Y direction from the other end to continuously from one end, the width of the nozzle slot and the depth of the nozzle slot not being constant at the same time.
  • the flowable substance is always conveyed over the entire length of the flow channel, regardless of the position in which the slide is located and thus regardless of how much the outlet opening is blocked off, i.e. from the inlet opening to the end of the flow channel facing away from the inlet opening.
  • the cross-sectional areas of the flow channel over its length and the cross-sectional area of the nozzle slot over its length are dimensioned so that the flowable substance is distributed evenly over the length of the nozzle slot, regardless of the position in which the slide is located.
  • the output of the flowable substance is largely constant over the length of the outlet opening of the nozzle slot that is not covered by the slide.
  • the nozzle slot preferably has a cross-sectional area over its length which is identical with regard to its shape.
  • the flow channel and / or the nozzle slot have an invariable volume. Regardless of the respective position of the slide, there is thus no change in the volume of the flow channel or the nozzle slot and consequently no further built-in components that would cause a change in the volume are to be provided within the nozzle body.
  • the device is structurally particularly simple because it is only necessary to provide the stationary nozzle body with the inlet opening, the flow channel and the nozzle slot.
  • a blocking means for interrupting the inflow of flowable substance into the flow channel is arranged upstream of the inlet opening.
  • This locking means which is in particular a valve that is in an open or a The closed position is always in the open position when the flowable substance is to be dispensed from the nozzle body, thus when the flowable substance is applied to the substrate.
  • the locking means is in its locking position when the slide is moved. If the slide is moved, the flowable substance is not conveyed through the inlet opening into the flow channel and the nozzle slot.
  • the flow channel preferably has a cross-sectional area that is essentially linearly variable over the length of the flow channel there, or a cross-sectional area whose change is a simply curved curve, thus a curve without a point of inflection.
  • This design takes into account to a particularly high degree the fact that the flowable substance is supplied in the area of one end of the flow channel and therefore, due to the discharge of the flowable substance through the nozzle slot, a larger volume of the flowable substance must be present upstream of the flow channel than downstream , further friction losses when conveying the substance.
  • the cross-sectional area of the flow channel decreases towards the other end of the flow channel, thus that end which faces away from the inlet opening.
  • the cross-sectional area of the flow channel at the other end of the flow channel is at most half as large as the cross-sectional area of the flow channel at one end.
  • variable cross-sectional area of the flow channel is preferably identical. Such a design can be produced in a structurally particularly simple manner and enables optimal flow conditions in the flow channel.
  • the change in the cross-sectional area of the flow channel and / or the width of the nozzle slot and / or the depth of the nozzle slot is in each case non-linear over its length, according to a single curved curve.
  • the nozzle body is structurally particularly simple if it has a first nozzle body part and a second nozzle body part which are connected to one another and between which the flow channel and the nozzle slot are formed.
  • the flow channel and the nozzle slot can thus be integrated particularly easily into one or the other nozzle body part or into both nozzle body parts, so that the nozzle body is formed when the two nozzle body parts are connected.
  • the nozzle body has strip-shaped nozzle body parts. The nozzle body parts are thus elongated and particularly well suited to form the flow channel and the nozzle slot in the nozzle body.
  • the flow channel and / or the nozzle slot is or are formed exclusively by depressions in a nozzle body part. This considerably reduces the construction and manufacturing costs of the nozzle body.
  • the cross-sectional area of the flow channel has the shape of a semicircle. Such a semicircular depression can be made particularly easily in the relevant nozzle body part.
  • the flow channel and the nozzle slot are formed in one nozzle body part and the inlet opening and a feed to the inlet opening are formed in the other nozzle body part.
  • the functionalities are structurally separated, namely the functionality of the flow channel and the nozzle slot are assigned to one nozzle body part and the functionality of the inlet opening and the feed to the inlet opening are assigned to the other nozzle body part. This not only simplifies the manufacture of the nozzle body, but also the connection of the nozzle body to a feed for the flowable substance.
  • the nozzle slot has a shape over its length such that the width of the nozzle slot between the flow channel and the outlet opening is constant or tapers continuously, in particular linearly, from the flow channel to the outlet opening.
  • the outlet opening and / or the nozzle slot and / or the flow channel is or are arranged horizontally in relation to their longitudinal extent, in particular the outlet opening is arranged above the flow channel.
  • This design or arrangement takes into account that the flowable substance, in the present case in particular flowable adhesive, is dispensed upwards for the purpose of application to a substrate which, arranged above the nozzle body, is conveyed via its outlet opening.
  • a vertical arrangement is entirely possible instead of the horizontal arrangement described.
  • edge banding This is used, for example, in the production of panel material in the woodworking industry. This involves applying glue to the narrow edges of the sheet material.
  • the outer area of the nozzle body having the outlet opening is flat and the slide has a flat section for contacting the nozzle body in this area, in particular for sealing contact under pretension.
  • the outlet opening of the application nozzle can preferably be completely covered by means of the slide, in particular coverable in a sealing manner. In the event of a standstill of the device for applying the flowable substance, in particular a PUR adhesive, this prevents the substance or the adhesive from reacting in the application nozzle, in particular from curing due to the moisture in the ambient air.
  • the device has a feeder which is provided with a contact surface which is arranged perpendicular to the longitudinal extension of the outlet opening to the side of the outlet opening, and the slide on a side facing the feeder has a contact surface which is parallel to the contact surface of the Investor is arranged. Regardless of the position of the slide, an insertion area for the respective substrate is thus formed between the contact surfaces of the feeder and slide.
  • This is, in particular, a book block that is held in a clamping device and is laterally contacted between the contact surfaces of the feeder and slide for its guidance.
  • the contact surfaces have surface areas which form converging insertion surfaces for the substrate.
  • a preferred area of application of the device according to the invention is the application of adhesive to the spine of a book.
  • the device should be able to be used as part of an adhesive application device in connection with digital printing and a downstream book production with the generic term “book on demand”.
  • the size of the edition can be at least one piece.
  • the application width of the adhesive on the book spine can be adjusted during the time between two adhesive applications on two consecutive book blocks, so that the adhesive can be applied to two consecutive books with different thicknesses in such a way that the quality of the adhesive application is sufficient .
  • This application width can only be in the range of 2 to 5 mm.
  • a closed adhesive system is used that takes into account the peculiarities of reactive curing hot melt adhesives such as PUR and minimizes the ingress of ambient air and thus moisture and keeps the mechanical stress on the adhesive low.
  • the slot nozzle used is of particular advantage.
  • the slot nozzle has an adjustment mechanism to adjust the application width of the adhesive on the respective book spine. After the adjustment, it is not necessary to retract the slot nozzle, so that the quality of the adhesive application on the first book after the adjustment is sufficient.
  • the slide and its drive are designed in such a way that the volume of the adhesive within the slot nozzle is not influenced during the adjustment of the position of the slide. This means that no adhesive escapes during the adjustment and no additional cavities arise that are not or only partially filled with adhesive.
  • the slot nozzle and the adjustment mechanism for the slide are designed in such a way that there are no moving parts that could stick. Due to the simple geometry of the adhesive-carrying parts, easy cleaning is possible.
  • the volume inside the slot nozzle is designed in such a way that all cavities exposed to adhesive are flowed through with adhesive and there are no so-called dead spaces in which the adhesive can age or harden.
  • the device according to the invention in addition to the developments described, is also characterized by a simple structure with a few parts that come into contact with the adhesive. This allows the device to be dismantled, cleaned and serviced with little effort.

This uniformity of the adhesive application is maintained over the entire adjustment range of the application width of the adhesive application. This uniformity is also maintained over a wide range of the viscosity of the adhesive.

  • the contact surface 17 of the feeder 18 is arranged perpendicular to the longitudinal extension of the outlet opening 40 to the side of the outlet opening 40.
  • the slide 26 On its side facing the feeder 18, the slide 26 has a contact surface 49 which, in a central region, is parallel to a central region of the contact surface 17 of the feeder 18. This respective middle area is laterally connected to the lead-in and lead-out bevels of the contact surfaces 17 and 49.
  • the feeder 18 and the slide 26 thus serve to guide the book block 3 when it is conveyed via the nozzle body 36.
  • the introduction of the book block 3 is made easier due to the converging insertion surfaces - contact surfaces 17, 49 -.
  • the nozzle body part 46 is provided with stepped bores 50 in the area of its facing end faces for receiving screws 51, which can be screwed into threaded bores of a base 52 of the application head 19, for fastening the stationary nozzle body 36.
  • FIG Figures 20 to 24 The specific structure of the application nozzle 10, which is designed as a slot nozzle, is shown in FIG Figures 20 to 24 shown for the second preferred embodiment.
  • the second embodiment according to Figures 20 to 24 differs only in the changed geometry of flow channel 38 and nozzle slot 39. Den Figures 20 to 24 it can be seen that the flow channel 38 in the region of the nozzle slot has a cross-sectional area that is continuously variable over the length of the flow channel 38 there. The change does not have to be linear; will normally be a single curved curve. This cross-sectional area of the flow channel 38 decreases towards the end 42 of the flow channel.
  • variable cross-sectional area of the flow channel 38 is identical.
  • the cross-sectional area of the flow channel 38 has the shape of a semicircle.
  • the cross-sectional area of the flow channel 38 at the other end 42 of the flow channel 38 is at most half as large as the cross-sectional area of the flow channel 38 at one end 41.
  • the nozzle slot 39 has a shape over its length such that the depth (extension in the Z direction) of the nozzle slot 39 between the ends 43 and 44 is constant.
  • the width BD of the nozzle slot 39 thus the extent of the nozzle slot 39 in the X direction, increases from the other end 44 to one end 43.
  • This width is variable along a single curved curve. This width is, for example, 0.32 mm in the section plane XXI-XXI, 0.35 mm in the section plane XXII-XXII, 0.4 mm in the section plane XXIII-XXIII and 0.53 mm in the section plane XXIV-XXIV constant depth of the nozzle slot of 1 mm over its length.
  • Fig. 25 shows the basic structure of the adhesive binding machine 1.
  • the transport clamps 8 of the adhesive binding machine are attached to the traction means 9 and are moved in the X direction at a defined speed. As a rule, this speed remains constant during production.
  • the book blocks 3 are clamped in the transport clamps 8 and moved along with the transport clamps 8.
  • the speed of the book blocks 3 is detected by the sensor 20 and passed on to the control device 12 for processing.
  • the book leading edge assigned to the front side 32 and the book trailing edge assigned to the rear side 34 are detected by the sensor 21 and forwarded to the control device 12 for processing.
  • the adhesive binding machine transmits the signals for the book block thickness to the control device 12 in a suitable manner, so that it can clearly assign the book block thicknesses to be processed to the book blocks to be processed.
  • the decisive factor here is that the control device 12 has the data on the speed and the book block thickness and can determine the beginning and end of each application of adhesive. How the data required for this get into the control device 12 can also be implemented
  • the adhesive is melted in the premelting device 4 and kept ready in flowable form.
  • the pump 14 conveys the adhesive held ready in the premelting device 4 via the supply line 5 and the adjusting element 22 or valve either to the application nozzle 10, while the adhesive is being applied to the book spine 2, or via the return line 6 back to the premelting device 4 optional pressure sensor 23 detected immediately in front of the actuating element 22 and transmitted to the control device 12.
  • the pressure sensor 23 is not absolutely necessary for a satisfactory function of the system and can be omitted or only temporarily installed for reasons of cost.
  • the slide 26 of the application nozzle 10 for adjusting the application width of adhesive is actuated, adjusted and adjusted via the adjusting mechanism 25 and the drive 28.
  • the signal and the activation from the drive 28 can be made available or made available either by the control device of the adhesive binding machine or by the control device 12 of the device 1.
  • the adjusting element 22 for supplying the adhesive to the application nozzle 10 is actuated by the control device 12 in such a way that the beginning of each application of adhesive and the end of each application of adhesive correspond exactly to the previously determined values.
  • the adjusting element 22 is designed as a switchover valve. In a first position of the actuating element 22, a flow from the supply line 5 to the application nozzle 10 is free and the return line 6 is blocked.
  • the supply of the adhesive to the application nozzle 10 is interrupted and the supply line 5 is connected to the return line 6 via a throttle 35 integrated in the adjusting element 22.
  • this throttle or a throttle element can also be built into the return line 6 as a separate component. If the supply of the adhesive to the application nozzle 10 by means of the adjusting element 22 is interrupted, the slide 26 is shifted to adapt to the new book block thickness, if necessary because of the changed thickness of the book block.
  • the drive 13 of the pump 14 is controlled with the aid of all the signals described above from the control device 12 in such a way that the adhesive application on the book blocks 3 has a clearly defined beginning, a clearly defined end and a uniform distribution over the length of the order. This takes place by means of a substantially volumetric delivery of the adhesive by means of the pump 14.
  • the theoretical volume flow of adhesive during the application is determined from the speed of the moving book blocks 3, from the application width and from the thickness of the adhesive applied to the book block 3.
  • the thickness of the application must be fed to the control device 12 as a parameter. This is usually done via an input terminal that is operated by the user of the device 1.
  • the default value for the order size can also be supplied to the control device 12 from the perfect binding machine or from a higher-level controller.
  • the pump 14 While the application of adhesive to the book blocks 3 is interrupted and the actuating element 22 is switched to the return of adhesive to the premelting device 4, the pump 14 generally delivers an adhesive volume flow that differs from the adhesive volume flow from the adhesive application. This volume flow of the adhesive during the return to the premelting device 4, i.e. during the circulation of adhesive, is so great that the adhesive pressure in front of the adjusting element 22 is as large as possible as during the adhesive application via the application nozzle 10 to the book spine 2.
