Description

The invention relates to a gluing machine for attaching a band of banding on an end face of a workpiece plate, with a portable, manually guided on the workpiece plate along machine housing, with an adhesive applicator for applying adhesive to a back of Umleimerbands and with a tape guide means for guiding the adhesive provided Umleimerbands to the end face of the workpiece plate for bonding with the end face.

Adhesive machines are known in which the adhesive is heated in a vessel. A circulation pump pumps the liquid adhesive in the direction of the band, where it wets or coats the band. Unused liquid adhesive flows back from the adhesive outlet towards the vessel or other collection container. For example, unpleasant adhesive vapors can result from the generally open guidance of the adhesive.

It is therefore the object of the present invention to provide an improved gluing machine.

To solve the problem is provided in a gluing machine of the type mentioned that a preparation arrangement of the adhesive-applying means for providing the adhesive in a suitable for applying the adhesive to the band edge liquid state in an upper region of the machine housing is arranged so that the preparation arrangement in a position of use, when the gluing machine is guided along the workpiece plate, above a tape outlet of the tape guide means for guiding the Umleimerbands is arranged on the end face of a workpiece plate, and that a glue channel for the liquid adhesive from the preparation arrangement with respect the use position down in the direction of the tape guide device to an adhesive outlet runs.

It is a basic idea that the preparation arrangement prepares the adhesive at the top of the gluing machine so that in the use position it runs downwards in the direction of the glue outlet. Gravity comes to help. The preparation of the adhesive of the preparation arrangement expediently comprises bringing it from a solid to a liquid state suitable for applying the adhesive to the band of banding. For example, the preparation arrangement heats the adhesive. However, the concept also makes it possible to use liquid adhesive, for example a glue, even at normal temperature. Furthermore, it is conceivable that the preparation arrangement heats a relatively viscous adhesive at room temperature so that it becomes less viscous.

This procedure has several advantages. For example, the gluing machine does not heat from below, but only in an upper region of the machine housing. As a result, the gluing machine as a whole is relatively cool, even when the glue is heated.

The adhesive supply can be introduced from above into the machine housing, so it is easier to access. For example, the gluing machine has an adhesive-providing space located in the upper portion of the machine housing for receiving an adhesive supply. The adhesive supply is preferably brought by the preparation arrangement in the liquid, suitable for application to the band edge condition and / or as - possibly even without prior heating - liquid adhesive conveyed to the adhesive outlet.

The adhesive-providing space may include, for example, a tank for liquid adhesive or adhesive granules. Preferably, the adhesive-providing space comprises a receptacle or receptacle for the adhesive.

The adhesive-providing space suitably has an opening at the top of the machine housing, through which the adhesive supply can be introduced into the adhesive-providing space. The opening is suitably closed by a lid. But it is also possible that the opening remains open, especially when block-like, for example, in such configured by adhesive cartridges adhesive is filled.

A viewing window in the region of the adhesive preparation space is advantageous, through which the adhesive supply is recognizable. Thus, the operator can easily check the existing adhesive supply. The viewing window is provided, for example, on a lid for closing the staging area. But it is also possible to provide the or a viewing window, such as a transparent wall, elsewhere.

The adhesive channel is expediently closed by means of a closing valve. Thus, the adhesive supply to the adhesive outlet is prevented, for example during breaks. But it is also possible that the adhesive outlet integrally has a valve member, with which it is closable. Thus, therefore, two variants are possible namely, that a closing valve is provided on the adhesive channel independently of the adhesive outlet and / or that a valve member of the adhesive outlet fulfills the closing function.

The closing valve also has the advantage that the adhesive supply area is closed, so that the gluing machine can be brought into oblique positions, for example, to the workpiece plate before starting work without the liquid adhesive gets into the environment.

The adhesive outlet expediently has an arrangement in a longitudinal extension of juxtaposed outlet openings for discharging the liquid adhesive. The series arrangement or arrangement of the outlet openings adjacent to one another makes it possible to apply adhesive uniformly over a width of the banding band.

Advantageously, the outlet openings are openable and closable by the valve member.

It is advantageous if the or a valve member is coupled in motion with a width adjustment for adapting the tape guide device to a respective width of the band Umleimerbands such that the valve member in response to a set at the width adjustment Umleimerband width of the Umleimerband width corresponding group of outlet openings for Ejecting the liquid adhesive opens or closes.

The valve member may in principle be designed so that it can not close all the outlet openings, that is, that it only serves in principle to keep a respectively required for the application of adhesive to the entire width of the band Umleimerbands open and not the group to close required outlet openings. In such an arrangement, for example, a separate closing valve may be arranged on the adhesive channel, ie that the valve member does not fulfill the closing function for the adhesive outlet.

However, a double function, so to speak, is preferred, i. in that the valve member is designed to open and close all outlet openings, thus enabling the function of a closing valve, and is additionally coupled to the width setting device in order to open and close the number of outlet openings corresponding to the width of the banding band as the adhesive is applied to the banding band , Preferably even open only so far that the exact required or an application thickness of adhesive on the band gluing corresponding adhesive can flow out of the outlet openings.

The gluing machine expediently has a heater for producing the liquid adhesive by heating a portion of adhesive stock comprising solid adhesive. The solid adhesive is present, for example, as adhesive granules or as a solid adhesive cartridge, for example as a kind of adhesive stick.

The heater is expediently arranged in the same way as the other components of the adhesive preparation arrangement in an upper region of the machine housing. Any resulting waste heat thus rises to the top and heats lower parts of the gluing machine or only comparatively little.

The heater is preferably thermally insulated by a conveyor which conveys the solid adhesive in the direction of the heater. Furthermore, a thermal insulation of the adhesive-providing space from the heater is advantageous, so that the adhesive supply located there does not stick. Preferably, the preparation arrangement has a pressure generating unit for generating a pressure on the liquid adhesive. The pressure generating unit acts, for example, on the still solid, to be heated adhesive. But it is also possible that, for example, an adhesive pump is provided for the liquid adhesive. The pump delivers the adhesive towards the glue outlet.

It is preferred if the pressure generating unit is designed to generate a substantially constant pressure on the still solid, to be transported in the direction of heating adhesive material.

A preferred embodiment provides that the pressure-generating unit comprises a conveying member for advancing the adhesive in the direction of the adhesive outlet and / or the heater.

A preferred variant provides that the pressure generating unit moves the conveyor member to a start position, wherein the conveyor member abuts the adhesive supply, and then partially back to a release position moves to allow the adhesive supply to expand when heated.

Below the adhesive outlet, a collecting container is expediently provided for collecting excess adhesive not applied to the banding band. The collecting container is detachably held on a container holder of the machine housing. Even if the gluing machine uses the glue very sparingly, a small volume of glue can always enter the environment, but this is absorbed by the catcher. The collecting container is expediently made of a flexible, deformable rubber or Plastic, for example an elastomer, so that the collected in the collecting container, cooled and thus hard plastic can be easily removed from the container.

In the gluing machine, it is advantageously provided that it has at least one workpiece guide surface provided for support and guidance on an upper side of the workpiece plate extending beyond the end face, so that the gluing machine, in its position of use, attaches the gluing tape to the end face of the workpiece plate on its upper side is supported, and that a tape outlet of the tape guide means for guiding the Umleimerbands is arranged adjacent to the end face of a workpiece plate next to the workpiece guide surface, so that the tape guide means in the operating position of the gluing machine leads the Umleimerband below the workpiece guide surface on the end face of the workpiece plate zoom.

It is a basic idea that the gluing machine is comfortably supported by the operator on the upper side of the work piece plate in addition to the end face to be coated with the gluing tape.

An advantageous embodiment of the invention provides that the workpiece guide surface comprises at least one guide surface provided on a boom protruding laterally in front of the machine housing. The boom is expediently designed as a handle. But it does not have to be that the boom is designed as a handle. Furthermore, it is possible that a plurality of arms are provided with corresponding workpiece guide surfaces, of which one or more expediently are designed as a handle.

It is useful if the boom is detachably arranged on the machine housing. Thus, it is possible, for example, differently shaped boom, for example, different sized workpiece guide surfaces or workpiece guide surfaces with different geometries having boom, if necessary, to attach to the machine housing.

In the case of the gluing machine, it is expediently provided that the preparation arrangement of the glue application device is designed to provide a volume of the adhesive at an adhesive outlet in a liquid state suitable for applying the adhesive to the gluing tape as a function of at least one adjustable and / or sensory detectable parameter is.

It is a basic idea that the amount of adhesive is adjusted so to speak optimally and a small, but sufficient amount of adhesive at the adhesive outlet for application to the band is ready.

For example, only a small amount of adhesive needs to be heated until the gluing machine is ready for use.

The preparation arrangement has, for example, a control device. The control device includes, for example, a microprocessor or other processing unit.

It goes without saying that control of a mechanical or partially mechanical type is also possible, ie that the preparation arrangement, as a function of the adjustment of individual components of the gluing machine, adjusts itself, as it were, to the adhesive volume to be delivered. The controller works eg proportionally. For example, one at the adhesive outlet provided valve member are taken by a Breiteneinstelleinrichtung for adjusting the tape guide device to a respective width of the Umleimerbands to optimally adjust the auszubringende adhesive volume.

The preparation arrangement thus operates as needed and adjusts depending on at least one or more parameters, the optimum amount of adhesive. The preparation arrangement has, as it were, a volumetric control.

Furthermore, the gluing machine can also be used, for example, in inclined positions without the adhesive getting into the environment. The preparation arrangement provides the amount of liquid adhesive actually required, so that it is reliably consumed and does not stick as excess adhesive, for example, the gluing machine or the workpiece plate.

Preferably, the preparation arrangement is arranged in an upper region of the machine housing, so that the preparation arrangement is arranged in a position of use, when the gluing machine is guided along the work piece plate, above a tape outlet of the tape guide means for guiding the gluing tape to the end face of the work piece. An advantage here is that the liquid adhesive flows downwards, so to speak, in the direction of the adhesive outlet. The inventive control of the adhesive volume is particularly advantageous in this context, namely because the liquid adhesive, for example, due to its gravity already flows down towards the adhesive outlet and the preparation arrangement, in particular their control device ensures that provided only so much adhesive becomes, as is actually needed. Thus, so get not too much glue in the direction of the glue outlet that could contaminate the gluing machine or its surroundings.

The preparation arrangement is expediently designed for such an exact provision of the adhesive volume in the measure required for wetting or coating of the adhesive band that essentially no excess adhesive drips off the band or the adhesive outlet. Of course, this does not mean that, for example, during a start-up phase, some adhesive may not get into the open, which is not being applied to the banding.

The at least one parameter can be detected by sensors, for which purpose suitable sensors are advantageously provided in the gluing machine, for example optical sensors, position sensors, tactile sensors, capacitive sensors, inductive sensors and the like.

It is also possible that the at least one parameter is adjustable, for example by an operator or a control device of the gluing machine itself.

The operator can specify, for example, a feed speed of the gluing machine or an adhesive quantity applied to the gluing tape on a control element, an operating interface or the like, which can then be detected by the gluing machine or its control device, for example as an operating input and thus parameters. It can also be provided a sensory scanning of a control element, with which the operator specifies the or at least one parameter.

Furthermore, it is possible for the control device to set the parameter itself, as it were, for example one Adhesive pump according to the elevator-carrying amount of adhesive or a width adjustment for adjusting a width of the band edge drives, which is to be processed, and thus knows the adjustable and set parameters so to speak themselves. For example, the control device to a stepper motor whose position is always known to control according to the at least one parameter.

As a parameter that takes into account the preparation arrangement or its control device in the provision of the adhesive volume, for example, the following are possible.

For example, the parameter includes a width value representing a width of the band of banding. This width value can be detected, for example, by sensors, for example by an optical sensor, a touch sensor or the like, which optically detects or scans, as it were, the band of banding or its respective width.

Preferably, a width setting device is provided for adapting the tape guiding device to a respective width of the banding band. For example, a tape guide sensor is configured to detect the width value to scan or detect a position of the width adjusting device corresponding to a width of the tape, for example, optically or tactilely. But it is also a forced adjustment conceivable that, for example, when adjusting the width adjustment for adaptation to the Umleimerband width, an actuator is entrained or adjusted, which serves to adjust the adhesive volume of the preparation arrangement. For example, as the actuator, a valve member a control valve that stops the adhesive flow.

The at least one parameter may, however, also include an adhesive thickness value which represents a layer thickness of the adhesive to be applied to the edge band. The adhesive thickness value can be adjusted, for example, on a user interface, by means of a setting switch or the like, on the gluing machine, preferably by an operator.

The at least one parameter may preferably include a feed speed value representing a feed rate at which the gluing machine is guided along the work sheet and / or the gluing tape is fed from the gluing machine towards the work sheet. With a correspondingly faster feed, correspondingly more adhesive volume is prepared, less with slower feed. The preparation arrangement thus adapts to the current requirements.

The preparation arrangement expediently has a quantity sensor for detecting a quantity of an adhesive supply located in an adhesive supply space of the gluing machine, which serves to produce the liquid adhesive. For example, the flow sensor may include a position of a conveyor member for conveying the adhesive toward the adhesive outlet. However, the quantity sensor can also be formed, so to speak, by the control device itself, that is, for example, it controls a conveyor drive for conveying the adhesive in the direction of the adhesive outlet with a control value, this control value then representing the pre-conveyed quantity of the adhesive and thus representing a quantitative value, the preparation arrangement, in particular their control device evaluates as a quantity value for volume-accurate generation of the adhesive volume.

However, the quantity sensor may also comprise, for example, a float or an optical sensor for detecting an adhesive supply in the form of granules. Furthermore, it is advantageous if an optical sensor for detecting a position of the adhesive supply relative to an outlet of the adhesive-providing space comprises. For example, a length of an adhesive stick or adhesive cartridge may be detected by such a quantity sensor. Of course, other measuring methods are also possible, for example capacitive measuring methods or the like, in order to detect an amount of the adhesive supply. The gluing machine then has a capacitive quantity sensor and on.

It is preferred if the preparation arrangement does not have to directly detect the volume of the adhesive actually flowing out of the adhesive outlet in order to optimally adjust its quantity. That would be possible in a variant of the invention. However, because sensory detection of the flowing adhesive volume may be relatively difficult, it is preferable if the preparation assembly determines the volume of adhesive needed at the adhesive outlet for applying the adhesive to the band without actually sensing to the adhesive outlet flowing volume of the adhesive is designed. The preparation arrangement accordingly operates with other parameters, for example the conveying speed with which the adhesive is conveyed in the direction of the band or adhesive outlet. The other parameters explained above, for example the feed rate of the gluing machine with respect to the work piece plate or the gluing tape with regard to the glueing machine, can also be used to make the preparation arrangement more exact Adjust the adhesive volume for the adhesive outlet.

Preferably, the preparation arrangement has a pressure generating unit for generating a pressure on the liquid adhesive. For this purpose, for example, a pump may be provided which conveys the liquid adhesive in the direction of the adhesive outlet. However, it is preferred that the pressure generating unit pressurizes a still solid adhesive or adhesive base in the direction of a heater for heating the still solid adhesive to a liquid adhesive.

It is preferred if the gluing machine begins to work, so to speak, with defined initial parameters. Preferably, adjusting means are provided for adjusting the or a conveying member for advancing the adhesive base material in the direction of the adhesive outlet in a defined pressure on the adhesive supply exerting starting position. For example, a thrust piston that conveys the adhesive base material toward the adhesive outlet or an upstream heater is moved to a defined initial pressure starting position before the actual adhesive delivery process begins.

An independent invention, the following measure represents. An adhesive machine of the type mentioned expediently has a preparation arrangement for providing liquid adhesive to an adhesive outlet of the adhesive-applying device. Advantageously, it is provided that the preparation arrangement includes a computation unit for calculating a length value, which represents a length of the band, which still depends on the currently set and / or sensory detected at least one parameter Adhesive can be provided. Output means are provided, for example a graphical display to indicate the length value. Thus, as it were a range indicator is present, which signals to the operator whether the pending for processing length of the workpiece plate can be provided with banding tape or whether he must first fill the adhesive supply. Thus, even work results can be achieved because the operator does not need to set the gluer to replenish adhesive during the process. It is not necessary for the operator to fill in the gluing machine with plenty of glue, so to speak. Rather, he can optimally use the adhesive as needed. This is also advantageous from the point of view that, for example, different colored or differently adhesive adhesives are pending for use and expediently as far as possible the adhesive still present in the gluing machine is first used up before another type of glue is introduced.

A consumption indication of the past consumption of adhesive and / or the current consumption of adhesive may also be provided in the gluing machine, e.g. on the display.

It is an advantage if the gluing machine has an operating interface for setting the at least one parameter. For example, the feed rate can be specified. It is also possible to set the application thickness of the adhesive on the banding band on the operating interface. The user interface has, for example, a graphical user interface.

Preferably, a fan concept or a cooling concept is provided in the gluing machine according to the invention. For example, a cooling device for cooling an interior of the machine housing is provided in the gluing machine.

An independent invention, in particular in connection with a gluing machine according to the preamble of claim 1, represents when the gluing machine has a suction connection for connecting a vacuum cleaner, so for example a suction hose, wherein a suction flow of the vacuum cleaner, for example for cooling the interior of the Machine housing is provided. The suction flow can also suck off adhesive vapors in an innovative way.

An adhesive machine 10 for gluing a Umleimerbands U to a workpiece plate W is supplied for example via a connecting cable 11 and / or an energy storage, not shown, eg a battery on board the gluing machine 10 with electrical energy.

At a main switch 15, the gluing machine 10 can be turned on and off.

The gluing machine 10 has a machine housing 20 with a lower housing part 21 and an upper housing part 22. The lower housing part 21 and the upper housing part 22 are firmly connected to each other. The terms housing lower part 21 and upper housing part 22 quite generally mean an upper area and a lower area of a machine housing. The machine housing 20 could of course also consist of one or two housing halves, which extend from an upper side to an underside of the machine housing and are connected to one another in the position of use vertically extending joint.

The gluing machine 10 can be lowered with a bottom or bottom wall of the housing base 21 on a substrate. On a rear side 23 of the machine housing 20 is a handle 24 for gripping by an operator. Between the lower housing part 21 and the upper housing part 22, a recess 25 is provided on a front part of the machine housing 20, in which the components of the gluing machine 10 leading and machining the banding band U are arranged.

On an upper side 26 of the machine housing 20 are controls for operating the gluing machine 10 and a lid 27, with which a staging space 28 for providing adhesive K is closed. The cover 27 is pivotally mounted, for example, with a pivot bearing 29 on a top side 26 providing wall 30 of the housing upper part 22 between a receiving opening 31 of the staging space 28 closing position and a releasing this open position. Preferably, a spring arrangement, for example comprising a leg spring, provided that loads the lid 27 in the closed position. The lid 27 is partially or wholly transparent, for example, consists of a correspondingly transparent plastic, so that an adhesive K located in advance in the staging area 28 is easily recognizable from the outside. Thus, the cover 27 thus forms a viewing window 32 for the staging area 28.

The lower housing part 21 has a cover plate 33, which covers a limited from the bottom of the housing base 21 and a peripheral wall 34 interior of the housing base 21. From the housing base 21, a support 35 which connects the upper housing part 22 with the lower housing part 21 extends. Also, the handle 24 acts as a connection between these two housing parts.

The recess 25 is bounded by the cover plate 33 and a wall 36 of the support 35 and finally a cover plate 38 arranged on a peripheral wall 37 of the housing upper part 22 on the underside.

In the recess 25 tape guide elements and drive elements of a tape guide device 50 are arranged. The tape guide device 50 includes, for example, an input roller 51 and an output roller 52, at least one of which is driven by a drive motor 53 (shown schematically). The drive motor 53 is accommodated, for example, in the lower housing part 21 and drives the input roller 51 and / or the output roller 52, for example directly, via a transmission, in particular a drive chain or the like.

The input roller 51 pulls the Umleimerband U in the tape guide device 50, namely a tape inlet 54, in, so that the Umleimerband U along a guide rail 55 along is guided and leaves the guide track 55 in the area of the output roller 52 at a tape outlet 56 so to speak again. The output roller 52 also fulfills the function of a pressure roller or pressure roller for pressing the Umleimerbands U to an end face S of the workpiece plate P.

The guide track 55 is S-shaped in plan view, for example. The guide track 55 comprises a plurality of guide surfaces, for example a groove 57 leading to the input roller 51 on the housing upper part 22, through which the banding band U can be pulled into the interior of the recess 25. The groove 57 is thus open in the region of the circumferential wall 37 and the input roller 51. The groove 57 has, for example, a curved course.

It may be provided instead of rollers in the manner of the input roller 51 and the output roller 52, other leading components, for example, corresponding sliding surfaces, running and driving wheels or the like. Furthermore, more or fewer rollers than the two input and output rollers 51, 52 may be provided, even non-driven rollers or rollers.

The input roller 51 may be opposed to further guide elements, such as a roller 58, which presses the Umleimerband U to the outer periphery of the input roller 51 at. In the further course of the guideway 55, further guide components for guiding the gluing tape U may optionally be provided, for example on the underside of the cover plate, but do not have to be provided.

An upper narrow side U2 which is in use abuts the cover plate 38 and is guided by it. The cover plate 38 provides a narrow side guide surface 59 for the narrow side U2. The cover plate 38 and thus the narrow side guide surface 59 is with respect to the machine housing 20 stationary, ie the upper narrow side U2 of the band Umleimands U has with respect to a height direction H of the machine housing 20 has a constant height position.

However, it would be readily possible to make the narrow side guide surface 59 movable, that is, for example, form on a plate body or other guide body, which is adjustable with respect to the height direction H of the machine housing 20, for example, to the upper housing part 22 or away, for example by a Spindle or an electric motor or other linear drive.

Such a measure is in fact taken at a narrow side guide surface 61, which forms part of a Breiteeinstelleinrichtung 60. The narrow side guide surface 61 leads a narrow side U1 of the band Umleimands U, which is opposite to the narrow side U2.

The width adjustment device 60 is used to adapt the tape guide device 50 to a respective width B of the band Umleimands U. The narrow side guide surface 61 is disposed on a guide body 62 which is adjustable with respect to the height direction H by means of an actuator 63.

The actuator 63 is presently a manual drive and can be operated with a handle member 64. A motor drive, for example an electric motor drive, is also possible without further ado. By a rotation of the handle member 64, a height position of the guide body 62 is adjustable. The handle element 64 has, for example, a spindle 67 which engages in a spindle nut 68 arranged in a guide body 62. The guide body 62 is further on spaced columns or guide rods 69 guided, which extend in the recess 25 between the lower housing part 21 and the upper housing part 22. The guide rods 69 engage in unspecified guide receptacles, for example through openings, of the guide body 62, so that the guide body 62 is linearly guided on the guide rods 69.

Further unspecified are recesses and passage openings on the guide body 62, which are provided for the input roller 51 and the output roller 52. Preferably, it is provided that the guide body 62 extends approximately over the entire bottom side of the recess 25, so the top of the top wall or cover plate 33 in the region of the recess 25, so that him leading components, such as the guide rods 69, a large design space available stands. Consequently, in any case, the guide body 62 is guided parallel with respect to the upper narrow side guide surface 59, so that the narrow sides U1 and U2 of the band Umleimands U are optimally supported over the entire length of the guide rail 55 length.

The narrow side guide surface 61 is formed by the bottom of a guide groove 65 facing the narrow side guide surface 59. The guide groove 65 is for example approximately U-shaped in cross-section and has a lateral recess into which an outer periphery of the input roller 51 projects. Thus, the input roller 51 configured as a driving roller is in driving engagement with the banding tape U when received in the guide groove 65 and facing the driving roller or input roller 51.

The input roller 51 and the output roller 52 are configured here as rollers. The input roller 51 and the output roller 52 expediently have on their outer circumference an elastic surface and / or a surface with a relatively high coefficient of friction on, so that they can drive the Umleimerband U optimally.

The input roller 51 and the output roller 52 are so high (or long) that they can be in driving engagement with a total width B of a band Umband U at maximum from the upper narrow side guide surface 59 away adjusted guide body 62.

The guide groove 65 merges into a guide belt 66 leading to the adhesive band at its free, non-adhesive-wetted or coated surface in the region of an adhesive outlet 71 of an adhesive-applying device 70. The guide wall 66 extends from the adhesive outlet 71 to the output roller 52, which presses the free, not provided with adhesive K flat side of the band Umband U in the direction of the end face S of the workpiece plate W. In the area of the adhesive outlet 71 also ends the bottom of the guide groove 65, that is, the narrow side guide surface 61. This is optional.

The adhesive outlet 71 comprises a tubular channel body 72 which has on its peripheral wall a number of outlet openings 73 arranged side by side. The series arrangement of the outlet openings 73 corresponds to a maximum possible width B of the band Umleimands U, so that it may be wetted or provided over its entire width B with adhesive K. The outlet openings 73 are oriented towards the guide track 55.

In an interior of the channel body 72, a valve member 74 is movably received. The valve member 74 may be linearly reciprocated along an adjustment axis 75 within the channel body 72 such that a channel portion 76 of the valve member 74 has a number of adjacent outlet openings 73 opposite, which corresponds to a width B of the respective Umleimerbands U. Liquid adhesive K can then flow through the channel section 76 to the outlet openings 73 and flow through them, so that the adhesive K coats or wets the banding band U. The valve member 74 is movably coupled to the guide body 62. The guide body 62 thus takes the valve member 74 into the appropriate longitudinal position with respect to the adjusting axis 75, so that, so to speak, the outlet width of the adhesive outlet 71 corresponds to the width B of the band U.

The channel portion 76 extends over a partial circumference of the valve member 74 and also only over a partial length of the valve member 74. The valve member 74 is also rotatable about the adjusting axis 75, so that the channel portion 76 in an open position, namely in each one to open Outlet openings 73 opposite rotational position through which adhesive K can flow to the outlet openings 73, and a closed position is rotatable in which the channel portion 76 is rotated away from the outlet openings 73, so that a solid portion of the valve member 74 closes all the outlet openings 73. Thus, therefore, the adhesive outlet 71 also fulfills the function of a closing valve.

The valve member 74 is adjustable by a servomotor 141 between an open position and a closing position closing the outlet openings 73, for example rotatable. The servomotor 141 is scanned by a rotational angle sensor 142, which detects, for example, a rotational angle value and outputs this as an adhesive thickness value 143 representing the layer thickness of the adhesive K and / or as a closing parameter 144 representing the open position or closed position of the adhesive through the Valve member 74 open or closed adhesive outlet 71 represents. It is also it is possible for the servomotor 141 to output the closing parameter 144 or the adhesive thickness value 143 directly, for example if it is designed as a stepping motor, or knows a control activating the servomotor 141, as the current closing parameters 145 and / or adhesive thickness value 143 depend on the activation of the Actuator 141 are.

The servomotor 141 drives an output 145 designed, for example, as an eccentric or shaft, which is coupled in a coupled manner to the valve member 74 via a coupling mechanism 146 and thus transmits the force of the output 145 to the valve member 74. The coupling mechanism 146 is slidably mounted on the output 145 of the servomotor 141 with respect to the height direction H, so that the output 145 can take the valve member 74 independently of the respective set width B of the width setting device 60. For example, the clutch mechanism 146 includes at least one fork-shaped end which is slidable with respect to the valve member 74 or, in the present case, with respect to the output 145.

A tape guide sensor 147 serves to detect the respective width B of the band U which is set on the band guide device 50. The band guide sensor 147 is coupled to the guide body 62, for example by means of a transmission element 148, for example a catch provided with a slot, so that he can detect the respective height position of the guide body 62 with respect to the height direction H. The tape guide sensor 147 outputs a width value 149 representing the width B.

The preparation of the adhesive K in a liquid state, which is suitable for application to the banding tape U, is performed by a preparation arrangement 80 in the upper part of the machine housing 20, namely in the upper housing part 22. The Preparation assembly 80 communicates with the staging area 28. In the present case, the steward assembly 80 includes or provides the staging area 28.

For example, a pressure generating unit 81 is provided which generates a pressure on the adhesive K in that it advances the adhesive pieces P or at least one of them in the direction of the adhesive outlet 71 and thus represents a conveyor 89. Alternatively, of course, an adhesive pump for pumping liquid adhesive K in the direction of the adhesive outlet 71 would be conceivable.

The conveying device 89 or the pressure-generating unit 81 comprises a conveying member 82 in the form of a piston 83, which is received in a housing 85 of the pressure-generating unit 81 in a linearly movable manner along an adjusting axis 84. The housing 85 provides the delivery space 28 in which the piston 83 or the delivery member 82 is movably received. In principle, the provisioning space 28 is an upwardly open movement chamber for the piston 83 and the delivery member 82. A drive 86 is provided which, for example, acts on a rod 87 protruding from the piston 83 and thus linearly displaces the piston 83 drives.

Adhesive pieces P, for example adhesive cartridges or adhesive sticks, can be inserted piecewise into the preparation space 28. The adhesive pieces P have, for example, a tablet-like or plate-like shape. An outer circumference of the adhesive pieces P corresponds to an inner circumference of the trough-like provisioning space 28, so that they are guided transversely to the adjusting axis 84 in the provisioning space 28. The preparation space 28 thus also forms a guide contour or a guide channel for the adhesive pieces P.

The pressure generating unit 81 conveys the adhesive pieces P toward a heater 90 which heats the adhesive K so that it becomes liquid and can flow to the adhesive outlet 71 via an adhesive channel 77.

The adhesive channel 77 is upstream of the channel body 72 or is formed by a part of the channel body 72. The channel body 72 can thus form the adhesive channel 77.

With a temperature switch 16, a temperature of the heater 90 can be preselected, to which the adhesive K is to be heated. The temperature switch 16 is, for example, two stages, with several stages or a continuous adjustment are readily possible.

The heater 90 includes, for example, a heating assembly 91, which has, for example, an electrically operable heating grid 95 in its interior. The conveyor member 82 thus pushes the adhesive pieces P in the direction of the heating grid 95, which heats the adhesive K, so that it emerges from the heating grid 95 liquid or pasty and flows into the adhesive channel 77.

The heater 90 is preferably thermally insulated from the machine housing 20. For example, the heating grid 95 is received in a plastic holder 92, which in turn is fixed in place in the upper housing part 22, for example screwed or by means of a plug-in assembly.

Furthermore, a provision of the space 28 to the heater 90 towards the front end cap body 88 is provided. This can be for cooling purposes, for example, metal, eg aluminum. An insulating ring or insulator body 96 disposed in front of the cover body for heating 90 expediently consists of plastic or some other thermal material insulating material, so that in any case the staging space 28 is not or at least to a lesser extent heated by the heater 90.

The heater 90 further comprises, for example, a heating unit 93, which holds or heats the adhesive channel 77, as it were, so that the adhesive K does not cool down there, becomes stronger and thus clogs the adhesive channel 77. For example, a tubular holder 94 is arranged on the channel body 72, in which an electrical resistance element, for example a heating cartridge, for heating the outlet valve, namely the adhesive outlet 71 is arranged.

• Eine Werkstück-Führungsfläche 100 der Klebemaschine 10 ist nämlich in Bezug auf eine in der Zeichnung dargestellten Gebrauchslage oberhalb der Bandführungseinrichtung 50 angeordnet. Mit der Werkstück-Führungsfläche 100 kann die Klebemaschine 10 in einer in der Zeichnung dargestellten Gebrauchslage auf eine Oberseite O der Werkstückplatte P aufgelegt und daran abgestützt werden. Die Klebemaschine 10 gleitet mit der Werkstück-Führungsfläche 100 an der Oberfläche O entlang, wobei sie gleichzeitig das Umleimerband U an der Stirnfläche S anklebt.

The physically conclusive concept such that the adhesive preparation takes place at the top in the machine housing 20 and the liquid adhesive K then flows downwards in the direction of the adhesive outlet 71 has ergonomic advantages, among other things. For example, the lower housing part 21 is not heated to any significant extent by the heater 90. Furthermore, the gluing machine 10 from the top with an adhesive reservoir, namely the adhesive pieces P, very easy to load. Furthermore, this results in a particularly favorable handling. However, it should already be noted that, of course, preparation or preparation of the adhesive K in the lower housing part 21 would also be possible in order to realize the concept described below:

• Namely, a work guide surface 100 of the gluing machine 10 is disposed above the tape guide 50 with respect to a use position shown in the drawing. With the workpiece guide surface 100, the gluing machine 10 can be placed in a use position shown in the drawing on an upper side O of the workpiece plate P and supported thereon. The gluing machine 10 slides with the workpiece guide surface 100 on the surface O along, while at the same time adheres the Umleimerband U on the end face S.

The workpiece guide surface 100 is disposed on a cantilever 101 which projects from the machine housing 20. The boom 101 is fixed to the housing upper part 22. The cantilever 101 has, for example, two arms 102, between which a plate 103 is arranged, the underside of which provides the workpiece guide surface 100. The workpiece guide surface 100 also extends into the region below the two arms 102, so is relatively large area.

Furthermore, extending between the two arms 102 at the end remote from the machine housing 20 end portion 104, a cross-beam, which serves as a handle 105. The free end regions 104 of the two arms 102 are angled relative to the plate 103 connecting or supporting arm portions 106, for example, in the use position upwards away from the workpiece guide surface 100. Between the handle 105 and the plate 103, there is a clearance or punch-through opening so that the handle 105 can be comfortably gripped or grasped by an operator.

At the ends 107 of the boom 101 remote from the handle 105, boom attachment means 108 are provided. By means of the boom attachment means 108, the boom 101 can be releasably attached to the machine housing 20. The fastening means 108 comprise, for example, holding projections 109, which are designed in the manner of pins or plug-in projections. The holding projections 109 can be inserted into holding receivers 110 on the machine housing 20. The holding receivers 110 are located, for example, on projections 39 which project in front of the circumferential wall 37 of the housing upper part 22.

Below the holding receptacles 110 or adjacent to the holding receptacles 110 support surfaces 112 are provided, which serve for the positive support of support surfaces 113 at the end faces of the free ends 107 of the arm portions 106. When the holding projections 109 engage with the holding receivers 110, the supporting surfaces 112 positively support the supporting surfaces 113 and thus the cantilever 101, so that a levering force exerted on the cantilever 101 by the machine housing 20 is applied not only to the holding projections engaging with the retaining receptacles 110 109, but also on the support surfaces 112, 113 is intercepted.

The boom 101 is also still with the machine housing 2 0 based on a latch assembly 114 locked and also still clamped, wherein the latch assembly 114 also forms a clamping device 115. It is understood that a lock or alternatively a jamming would be possible. On one or both of the holding receptacles 110 serving as a bolt and clamp screw 116 is provided which can be screwed into a corresponding in the holding receptacle 110 ausmündendes thread 121. The screw 116 has an actuating head 117, which is designed as a handle. Thus, the latch assembly 114 can be operated manually and without tools. A free end of the screw 116 engages in a configured, for example as an annular groove latch receptacle 118 to the respective retaining projection 109 a.

As a result, at the same time still a clamping function can be realized. The screw 116 may, for example, be screwed tangentially or radially into a clamping position in which it clamps the holding projection 109 in the holding receptacle 110. For example, then a free end of the screw 116 is supported at the bottom of the latch receptacle 118.

The plate 103 is not sufficient in the state mounted on the machine housing 20 up to the peripheral wall 37. Rather, between the plate 103 and the machine housing 20, a viewing window 119 is formed through which an operator from above can look at the work area next to the output roller 52. A marking 120, for example a dashed marking, points to the region where the banding band U is to be applied to the end face S.

With a switch 17 on top of the handle 24, a collection of Umleimerbands U can be started, i. the tape guiding device 50 pulls the banding tape U in from the tape inlet 54. In this case, preferably a not visible in the drawing switching device, for example, a light barrier is provided to turn off the drive motor 53 so that a front free end E of Umleimerbands U is brought or pulled in a start position, which correlates with the mark 120.

One recognizes the further procedure, for example, from the synopsis of FIGS. 2 and 3 where the gluing machine 10 is first placed with its workpiece guide surface 100 on the surface O and is then displaced in the direction of the end face S in order to begin with the gluing of the band Umleimands. For example, the marking 120 is positioned in alignment with a transverse side Q of the work piece plate W, and then the gluing machine is displaced by a displacement path 124 toward the work piece plate W, namely the end face S.

Then a feed switch 18 is to press, which puts the gluing machine 10, so to speak, in the correct working mode, ie that the Umleimerband U is coated with adhesive K and at the same time adhered to the end face S. The drive motor 53 and thus the tape guide device 50 thereby ensure the advancement of the gluing machine 10 along the end face S, ie the Pressure roller or output roller 52 rolls so to speak on the already glued on the end face S Umleimerband U and pushes the gluing machine 10 gluing machine 10 toward the still unprocessed area of the workpiece plate W. With the feed switch 18 can also be a feed rate 165 are selected , for example, in 2 or more stages or continuously.

When resting on the workpiece surface O workpiece guide surface 100 is a center of gravity of the gluing machine 10 below the surface O, namely the machine housing 20 with the relatively heavy drive components and guide components for the Umleimerband U. Thus, therefore, the gluing machine has a tendency to tilt in the direction the end face S and thus for pressing the Umleimerbands U to the end face S. This facilitates the handling of the gluing machine 10th

It would also be conceivable for a bearing arrangement 122, for example with a pivot bearing and / or a sliding bearing, to be provided in the region of the coupling of the arm 101 to the machine housing 20, so that the workpiece guide surface 100 also extends into a schematically indicated oblique position 100a or angular position 123 is adjustable with respect to a normal of the tape outlet 56. Thus, for example, workpiece plates can be processed, the end face is not perpendicular to the top O as in the workpiece plate W, but at a non-rectangular angle.

In the above and following description, it is assumed that the position of use of the gluing machine 10 and the corresponding "top" and "bottom" formulations refer to an approximately horizontally oriented work piece plate W. Of course, the workpiece plate W could also be at an angle, without this seriously the function of the gluing machine impaired. Rather, the innovative concept of the gluing machine 10 also allows operation in any inclined positions, for example with a horizontal to the horizontal inclined workpiece plate W and / or in a non-rectangular inclination with respect to the surface O, for example, the angular position 123 in accordance FIG. 1 without this pollution of the environment or the gluing machine 10 would be to be feared.

In the position of use or in any case a substantially horizontal position of the gluing machine 10 may be collected from the adhesive outlet 71 dripping adhesive residues of the adhesive K through a collecting container 40. The collecting container 40 has, for example, a handle 41, with which it can be grasped by an operator. For the collecting container 40, a container receptacle 42 is provided on the peripheral wall 34. It is preferred that a peripheral wall 43 of the collecting container 40 does not protrude in front of the envelope of the peripheral wall 34, so that the collecting container 40 can not get caught with, for example, the workpiece plate W. The collecting container 40 is made of a resilient or elastic material, for example rubber or an elastomer, so that it can be deformed in order to more easily remove the adhesive K from the interior of the collecting container 40 and, for example, to dispose it in a refuse container M.

An innovative concept, which of course is not limited to the design principle of the gluing machine 10 according to the drawing, constitutes an independent invention. It would also work in connection with, for example, a gluing machine which processes the glue in a lower casing part, the other Drive principles or even later described intelligent control for adhesive preparation does not have.

On the machine housing 20, in particular on the lower housing part 21, a suction connection 12 is provided, to which a suction hose or pipe of a vacuum cleaner can be connected. The suction connection 12 communicates with the working space of the gluing machine 10, where the adhesive K is applied to the gluing tape U. For example, a throughflow channel, which is not visible in the drawing, runs through the interior of the housing lower part 21 away from the region of the outlet openings 73 in the direction of the suction connection 12. A vacuum cleaner connected there thus possibly sucks in the area of the adhesive outlet 71 resulting adhesive vapors directly on site. Of course, it is advantageously or alternatively possible that the suction port 12 communicates with other areas of the gluing machine 10, for example, with the upper housing part 22, so that, for example, in the region of the heater 90 resulting adhesive vapors are also sucked. The operator is thus optimally protected from unfavorable odors, which can also be hazardous to health.

An improvement may also represent that the suction port 12, a filter 13, for example, an activated carbon filter, upstream, to filter out the adhesive vapors from the suction flow to the vacuum cleaner, or at least reduce its scope.

In addition to the suction connection 12 or as an alternative to it, it would also be possible, for example, for a fan 14 to remove an air flow from the adhesive outlet 71 or from another region of the gluing machine 10 to be vented, for example in the direction of the filter 13 or in any case generated by the operator, the air above the gluing machine 10 during their operation inhales.

It is in itself advantageous if, for example, regions of the gluing machine 10 which are not to be heated but are to be cooled are cooled, for example the provisioning space 28, so that the adhesive supply located there is not heated and possibly glued. The fan 14 can therefore also be advantageous without having a suction effect.

The operation of the gluing machine 10 is also facilitated by providing a supply means 200 for providing a supply of gluing tape U during work operation, i. So when sticking the Umleimerbands U to the end face S, entrains. The provision device 200 comprises a support body 201, which projects laterally in front of the machine housing 20 in the manner of a shelf, in which a winding receptacle 202 for receiving a tape roll C is provided. The tape roll C is rotatably mounted in the winding receptacle 202, so that a free end E of the band Umleimands U from the interior of the winding receptacle 202 can escape through a tape outlet 203 of the supply device 200. The belt outlet 203 communicates with the belt inlet 54 of the belt guide device 50, namely lies opposite the belt guide device 50, so that the edge band U runs or flows in or out directly from the delivery device 200 into the belt guide device 50, so to speak.

The promotion of Umleimerbands U out of the winding receptacle 202 takes over, so to speak, the tape guide device 50 and their drive components. The input roller 51, so to speak, pulls the banding strip U out of the winding receptacle 202.

The winding receptacle 202 is bounded laterally by a bottom wall 204 and by a peripheral wall 205 of the support body 201. The peripheral wall 205 has a plurality of lateral recesses 206, through which the operator turns the tape roll C from radially outward can take. As a result, the insertion or removal of the tape roll C in or out of the winding receptacle 202 easier.

The recesses 206 are bounded by upstanding support portions 207 of the circumferential wall 205 in the circumferential direction. At the support portions 207 each projecting abutment protrusions 208 are provided radially inward in the direction of a center of the winding receptacle 202. The tape roll C is held radially outward between the abutment projections 208 and the bottom wall 204. There, therefore, support the narrow sides U1 and U2 of Umleimerbands U with several turns of the tape roll C from. Since the tape roll C tends to unwind, its radially outer periphery presses against the inside of the peripheral wall 205, where then the abutment projections 208 can fulfill their holding function or hold-down function.

In the center of the bottom wall 204 is a support projection 209. For example, a peripheral wall 210 protrudes upward in front of the bottom wall 204. The peripheral wall 210 extends around a passage opening 211 of the bottom or the bottom wall 204 and projects upwards in front of the bottom wall 204. The support projection 209 may support the tape roll C inside. The support projection 209 can also serve as a winding aid for winding the Umleimerbands U to the tape roll C.

The bottom wall 204 may also have further recesses or openings, so that it extends in total from the passage opening 211 away star-shaped in the direction of the support portions 207. Furthermore, it is advantageous if at least one sliding projection 213, for example sliding ribs or the like, are provided on the bottom wall 204 and / or on the inside of the circumferential wall 205, on which the tape roll C can easily slide along.

By way of example, a roller 212 is also shown, on which the tape roll C can roll during unwinding into the tape inlet 54. Of course, further such rollers 212 are readily possible.

The belt outlet 203 is located at a connecting portion 214 of the supply device 200. The connecting portion 214 projects outwardly in front of the peripheral wall 205. On an upper side 215 of the connecting portion 214, the tape outlet 203 is arranged. The tape outlet 203 are preceded by guide contours 216 for guiding the band Umleimands U in the direction of the tape inlet 54. The guide contours 216 comprise, for example, a guide slot 217 which opens directly into the strap outlet 203 and which, as it were, widens in the direction of the winding receptacle 202. There is a funnel-shaped opening into the guide slot 217 insertion receptacle 218 for inserting the Umleimerbands U in the guide slot 217 and thus the tape outlet 203rd

It would then be conceivable to arrange the provision device 200 fixedly on the machine housing 20, for example fixed to the housing lower part 21 or else with a component movably mounted on the machine housing 20, for example on the guide body 62 of the width adjustment device 60.

Also a in FIG. 7 schematically indicated bearing device 240 for the movable mounting of the supply device 200, for example on the housing base 21, would be possible. On the basis of the bearing device 240, the supply device 200 is mounted, for example, for positioning relative to the belt inlet 54 so as to move in a sliding and / or pivotable manner on the machine housing 20. At the storage device 240, the supply device 200 may be arranged fixed or detachable, eg screwed and / or hooked and / or locked or with reference to the below-explained fastening means 220th

The fixed or detachable arrangement of the supply device 200 on the guide body 62 or the bearing device 240 is advantageous because the bottom of the winding receptacle 202 and in particular the tape outlet 203 is always in the correct height to the tape inlet 54 of the gluing machine 10, regardless of what width B of the band U is set.

The detachable connection of the provision device 200 with the base gluing machine 10, in this case the guide body 62 is realized by means of fastening means 220. The fastening means 220 comprise connecting projections 221 arranged on an end face 219 of the connecting portion 214 and having retaining seats 222. The connection projections 221 with the holding receivers 222 form, so to speak, holding eyes. On the guide body 62 matching holding projections 223 are arranged in the holding receivers 222, in which the holding receivers 222 can be hung. In this case, the connecting portion 214 is supported with its end face 219 on an opposite end face of the plate-shaped guide body 62. Thus, therefore, the carrying body 201 or the provisioning device 200 tends to tilt downwards on the upstanding holding projections 223 and is supported laterally on the guide body 62 with its end face 219 due to the lever formed by the supporting body 201 protruding or protruding from the machine housing 20.

This hook connection between providing device 200 and gluing machine 10 can be locked by a locking device 230. The locking device 230 comprises a, for example, pivotally mounted on the support body 201 latch 231, which engages and out of engagement with the guide body 62 of the width adjustment 60 can be brought. For example, the latch 231 could engage in a lateral opening on the guide body 62, so that the holding receivers 222 are no longer movable up out of the hook or holding projections 223. In the present case, the latch 231 engages under the guide body 62 in its locked position. Of course, a sliding bar or the like would readily be possible, which fulfills this functionality.

To actuate the bolt 231 is a handle member 232, for example, a slide. When the handle member 232 is moved toward the guide body 62, the locking means 230 locks the providing means 200 to the guide body 62; if the handle member 232 is moved away from it, the providing means 200 can be suspended from the guide body 62, at any rate, removed from the gluing machine 10.

The provisioning device 200 would also work well in connection with a gluing machine that is less innovative, in any case follows another technical concept. For example, the adhesive preparation in the housing lower part 21 could take place or else a support than with the above from the top of the workpiece plate O W supporting workpiece guide surface 100, then still the provision of the tape roll C directly on the machine housing 20 is advantageous.

An operating interface 150 for setting functional parameters of the gluing machine 10 is furthermore provided on the machine housing 20. The operating interface 150 includes, for example, a display 151, for example, with a temperature display 156, which indicates a heating temperature or current temperature of the heater 90, a level indicator for the level of the adhesive supply in the adhesive-providing space 28, etc. Furthermore, an adhesive amount indicator 157 may be provided, which indicates the currently applied to the band Um U-adhesive amount.

A range indicator 152 of the operator interface 150 is particularly advantageous. The reach indicator 152 shows e.g. in a unit of length, for example meters, the length of the band U, which can still be processed with currently set operating parameters.

Operating parameters of the gluing machine 10 can be set by means of operating keys 154, for example a temperature for the adhesive K can be preselected, a feed rate can be preset or the like. Furthermore, display parameters can also be changed, for example, whether the length of the band U, which can still be processed, is to be displayed in meters or in inches, or also the unit of measure for the temperature display 156. A respective functionality of the control keys 154 may vary in the respective operating context change, which is indicated by function indicators 155 above the control buttons 154. For example, various operating menus can also be selected via the operating buttons 154.

The pressure generating unit 81 is for generating a constant pressure on the adhesive pieces P and thus for generating a constant pressure on the liquid adhesive K flowing out of the adhesive outlet 71. For example, e.g. a pressure sensor and / or a pressure control may be provided.

The pressure generating unit 81 is configured to generate a constant pressure as follows. An electric motor 129 of the drive 86, which is in FIG. 14 only with one output, namely one Worm 130 drives a worm wheel 131. The worm 130 meshes with a ring gear on the outer circumference of the worm wheel 131. The rod 87, which projects in front of the piston 83 or the conveying member 82, is designed as a spindle, which is drivable by a spindle nut 132. The spindle nut 132 is rotatably supported, but axially non-displaceably, by an end wall 138 bounding the staging area 28. The spindle or rod 87 penetrates a passage opening 137 on the end wall 138 and the spindle nut 132.

The spindle nut 132 is driven by the worm wheel 131. For this purpose, the spindle nut 132 has at its outer periphery a toothing which engages in a non-visible in the drawing internal teeth of a receptacle 140 of the worm wheel 131. In any case, the spindle nut 132 in the worm wheel 131 with respect to the adjusting axis 84 is displaceable, but rotatably received. Thus, when the worm wheel 131 rotates, it takes the spindle nut 132 with it, whereby the designed as a spindle rod 87 can be moved axially.

The drive 86 further comprises an axial extension of the adjusting axis 84 relative to the end wall 138 axially fixed, for example screwed to the housing 85 cover 134. In a receptacle 139 of the cover 134, the worm wheel 131 and the spindle nut 132 are added.

A spring 133 is supported on a bottom of the receptacle 140 of the worm wheel 131, in which the spindle nut 132 is received, from the front side and acts on the worm wheel 131 in the direction of the end wall 138th

When adhesive pieces P are filled in the supply space 28, the conveying member 82 / the piston 83 moves in the drawing to the left, ie away from the heater 90, so that as much as possible Space for introducing the adhesive pieces P ready. For this purpose, for example, a control button 153 to press. Then drives the motor 129 of the drive 86 with its worm 130 to the worm wheel 131, this the spindle nut 132 and this in turn the spindle or the rod 87. As a result, the piston 83 moves in the drawing to the right, at least in the direction of the heater 90, and pushes the adhesive pieces P to the heater 90 back. The spindle or the rod 87 is secured with respect to the adjusting shaft 84 against rotation. For example, the piston 83 is secured against rotation in the staging area 28.

A position sensor 135, such as a micro-switch, serves to detect the position of the spindle nut 132 and thus indirectly to detect the position of the conveying member 82. Namely, when the piston 83 abuts with a predetermined pressure on the adhesive pieces P in the staging space 28, the spindle nut 132 the rod 87 / spindle no longer driving in the direction of an adjustment in the direction of the heater 90, but rotates on the spindle or rod 87 in a sense away from the heater 90, wherein it exerts an increasing force on the spring 133, which finally an example operated as a lever transmission member 136 is actuated, in turn, the position sensor 135 triggers. Then, a predetermined pressure on the adhesive pieces P is reached. Now there is a possibility that the drive 86 simply shuts off.

It is preferred, however, that the motor 129 driving the worm 130 still runs somewhat in the sense of relaxing the pressure on the adhesive pieces P. The position sensor 135 thus triggers a reversal of the motion of the drive 86. The motor then still runs back a predetermined distance, so that the arrangement is relaxed to the extent that the adhesive can expand when switching on the heater 90 by a certain amount and thereby no excessive pressure on the closing valve, at least in the direction the adhesive outlet 71 exerts, but a defined, depending on the temperature of the heater 90 pressure.

The functions of the gluing machine 10 are controlled by a control device 160, preferably a microprocessor control. The control device 160 includes, for example, a processor 161 and a memory 162 in which one or more control programs 163 are stored.

For example, the controller 160 receives a signal from the tape feed switch 17 and accordingly drives the drive motor 53.

Further, the controller 160 may also drive, for example, the actuator 141 to fully open and close the adhesive outlet 71, or may also drive the adhesive outlet 71 partially in proportion to the desired adhesive application thickness.

Finally, the control device 160 also controls the motor 129 of the pressure-generating unit 81 or of the conveyor 89.

The control device 160 can also be controlled by the operating interface 150, for example by means of the operating keys 154 and, in turn, in turn directs the display 151 to suitable displays.

The control device 160 now ensures that only so much adhesive K is prepared that no or only insignificantly drops adhesive K from the adhesive outlet 71.

The controller 160 is, for example, a component of the preparation assembly 80 for providing a volume of the adhesive K at the adhesive outlet 71. The control device 160 controls the components of the preparation arrangement 80 involved in dependence on at least one adjustable and / or sensor-detectable parameter such that it increases the volume of the adhesive K for application to the adhesive outlet Provide 71 in a suitable for application to the Umleimerband U liquid state in the exact size possible. The parameters are, for example, at least one parameter sensed by sensors, for which purpose suitable sensors are provided, or parameters which can be set, for example, on the operating interface 150, for example a layer thickness of the adhesive K which is to be applied to the band U. However, the adjustable parameters can also be detected by the control device 160, so to speak, by recognizing its respective position as a parameter when controlling, for example, the motor 129 and / or the drive motor 53 and / or the servomotor 141.

The so-called volumetric control of the control device 160 only opens the closing valve realized by the valve member 74 when adhesive K is actually to be applied to the banding band U. The amount adjustment is so sensitive and accurate that not too much and not too little adhesive K is applied.

Further, the controller 160 evaluates, for example, the closing parameter 144 and / or the adhesive thickness value 143.

Further, the controller 160 is also configured to evaluate the width value 149.

The width value 149 could also be known to the controller 160, for example, by having a (not shown) Actuator, such as a stepper motor, for adjusting the width adjustment 60 controls and thereby knows its correlating with the width B position.

Depending on, for example, the feed speed 165 or its value, which is set on the feed switch 18, the width value 149 representing the width B of the band A and thus the width of the adhesive layer to be applied, and the adhesive thickness value 143, the control device 160 controls the conveyor 89 and / or Their motor 29 so that always the drip-free exactly matching amount of volume of the adhesive K for coating the Umleimerbands U exits from the outlet openings 73.

Finally, the control device 160 also knows the exact position of the motor 129 by the exact starting procedure described above after the insertion of adhesive pieces P into the supply space 28, which ultimately represents a quantity parameter 164 for the existing adhesive supply. Of course, a sensory detection with, for example, an optical sensor or a weight sensor or the like of the adhesive supply in the staging area 28 would also be possible. In any case, the motor 129 so to speak contributes its position signal to a calculation of a range information.

Namely, based on the aforementioned parameters, the control device 160 is able to calculate in advance from the still existing adhesive stock in the staging area 28 which length of Umleimerband U can still be coated with adhesive K. The range information is output by the control device 160 at the operating interface 150 as range display 152.
