Description

The invention relates to a gluing machine for attaching a gluing tape to an end face of a work piece according to the preamble of claim 1.

Such a gluing machine is for example in US 4358337A or WO 85/01009 A1 or WO 00/53387 A1 explained.

The banding strip is introduced, for example, from the side into the machine housing, in any case the band guide device, and then processed by the gluing machine, namely glued to the end face of the workpiece plate. The operator must provide sufficient length of banding. The banding strip is long and therefore not readily feasible with a correspondingly long, to be provided with banding band end face of the workpiece plate.

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

To solve the problem, a gluing machine according to the technical teaching of claim 1 is provided.

It is a basic idea that the banding band wound up to the tape roll is ready in the winding receptacle and, so to speak, is handled by the gluing machine according to the work progress. Thus, the band provided as a supply band is stowed compact. The handling of the gluing machine is thereby facilitated. A free, still unprocessed Thus, the end of the band does not lurch around in the environment, for example, but is arranged directly and neatly on the gluing machine. The coiled cover band provided in the delivery device is much less susceptible to damage or soiling.

The belt guiding device preferably has a drive, for example with at least one drive roller or drive roller, for driving the banding band and thus for unwinding from the band lap.

It is also possible that the tape roll is driven directly by a conveyor drive of the supply device, so that corresponding lead band is conveyed forward in the direction of the tape inlet. For example, the tape roll can be driven by a rotary drive.

• Bevorzugt weist die Klebemaschine eine Breiteneinstelleinrichtung zur Anpassung der Bandführungseinrichtung an eine jeweilige Breite des Umleimerbands auf, wobei die Breiteneinstelleinrichtung mindestens eine bezüglich der Breite des Umleimerbands verstellbare Schmalseitenführungsfläche zur Führung einer Schmalseite des Umleimerbands aufweist. Die Bereitstellungseinrichtung ist mit einem die Schmalseitenführungsfläche aufweisenden Führungskörper fest verbunden oder bewegungsgekoppelt, so dass eine Relativposition der Wickel-Aufnahme zu der Schmalseitenführungsfläche unabhängig von der jeweiligen Position des Führungskörpers konstant bleibt. Mit anderen Worten nimmt die Breiteneinstelleinrichtung die Bereitstellungseinrichtung bzw. zumindest deren Wickel-Aufnahme sozusagen in Abhängigkeit von der Breite des Umleimerbands mit.

According to the invention, a mobility of the provisioning device is provided to the effect that an adaptation to a respective width of the band or banding a positioning relative to the tape inlet of the tape guide device is possible. This increases the variability and usability of the delivery facility. For example, a bearing device for pivotally and / or slidingly movable mounting of the provision device is provided on the machine housing. The bearing device may comprise, for example, a bearing which is arranged on the machine housing and which supports the provisioning device individually. But it is also possible that, so to speak, a double use takes place, which means that the width adjustment device described below simultaneously fulfills the function of the storage device:

• Preferably, the gluing machine has a width setting device for adapting the strip guiding device to a respective width of the gluing strip, wherein the width setting device has at least one narrow side guiding surface adjustable with respect to the width of the gluing strip for guiding a narrow side of the gluing strip. The supply device is firmly connected or motion-coupled to a guide body having the narrow-side guide surface, so that a relative position of the winding receptacle to the narrow-side guide surface remains constant independently of the respective position of the guide body. In other words, the width adjusting device takes the provision device or at least its winding receptacle, so to speak, depending on the width of the band.

By way of example, the provision device or its winding receptacle is taken along in the direction of a workpiece guide surface provided for guiding on the workpiece plate when a narrow band of banding is to be glued onto the workpiece plate.

The winding receptacle is preferably designed for rotatable mounting of the tape roll. Thus, therefore, the tape roll in the winding receptacle or at least rotate relative to a housing or frame of the supply device.

The tape reel, for example, be rotatably received in the winding receptacle. As such, the winding receptacle may be stationary relative to a housing or frame of the providing device.

But it is also possible that the winding receptacle has a pivot bearing for rotatably supporting a holder which is provided for holding the tape roll. The holder may for example comprise a coil on which the tape roll is wound. The holder may also include, for example, a kind of turntable on which the tape roll rests.

Preferably, the winding receptacle comprises at least one sliding projection and / or a roller, e.g. a wheel or a roller, for the radially outer guide of the tape roll. Thus, the tape roll can easily slide or roll along the inner periphery of the take-up roll.

The winding receptacle expediently has a winding aid or a dome or a mandrel, which is designed to wind up the tape roll. For example, the winding aid stands up from a bottom of the winding receptacle. It is preferred if the winding receptacle a support projection for Supporting the tape roll, in particular for centrally guiding the tape roll, wherein the support projection projects into a central interior of the tape roll up in front of a bottom of the winding receptacle.

It is advantageous if the tape roll not only loosely rests, so to speak, in the winding receptacle, but is held by one or more, for example in the form of hooks, abutment projections of the winding receptacle. For example, such an abutment projection faces a bottom of the winding receptacle, so that the tape reel is held between the bottom and the at least one abutment projection.

Preferably, the at least one abutment projection or a plurality of abutment projections project radially inwards from a circumferential wall of the winding receptacle. Since the tape roll usually has a tendency to autonomous unwinding, in the manner of a spring, it presses itself, so to speak, radially outward against the peripheral wall and is held there by the at least one abutment projection.

It is to be noted at this point, however, that of course, a lid may be provided which completely or partially covers or closes a receiving opening of the winding receptacle in a closed position and releases the receiving opening in an open position. Through the receiving opening, the tape roll can be inserted into the winding receptacle.

The provision device is expediently designed in the manner of a shelf.

The supply device projects, for example, laterally in front of the machine housing of the gluing machine.

Preferably, the winding receptacle is designed in the manner of a trough. For example, the winding receptacle is open at the top, so that the tape roll can be easily inserted into the winding receptacle or also removed therefrom, for example, when another cover tape is to be processed.

The providing device may form an integral part of the machine housing. Consequently, it is thus possible for the machine housing to have the winding receptacle integrally. However, a detachable arrangement of the provision device on the machine housing is preferred. For this purpose, fastening means are provided.

The fastening means comprise, for example, at least one latching device and / or a hook arrangement and / or a screw arrangement and / or a latch arrangement. Thus, therefore, the supply device can be latched, hooked, screwed or locked, for example, with the machine housing or any combinations thereof.

A preferred embodiment of the invention provides that the fastening means has at least one pair of holding receptacle and retaining projection. Preferably, several such pairings, for example two, are provided. The retaining projection is, for example, peg-like. With the holding projection and the holding receptacle, the providing device can be detachably fastened to the machine housing. For example, the supply device to the machine housing, in particular the aforementioned guide body width setting, on or mounted.

It is preferred if the connection of retaining projection and retaining receptacle can be locked or latched. For this purpose, for example, a locking device and / or a locking device is provided.

Conveniently, at least one guide contour for guiding the band of banding in the direction of the band inlet of the machine-side band guiding device is located at the band outlet of the provisioning device. For example, a guide slot is provided. But it is also possible that guide roller body or the like other guide body are provided.

Advantageously, it is provided in the gluing machine 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 advantage may be a favorable center of gravity of the gluing machine. Furthermore, it is possible for the provision device and / or the tape guide device Adjust below the workpiece guide surface to the respective width of the band.

A focus of the gluing machine in its position of use is expediently below the plane of the workpiece guide surface. Below the plane of the workpiece guide surface in the position of use, the supply device is also advantageously arranged with respect to the machine housing. Thus, therefore, so to speak, the gluing machine tends to tilt in the sense of a pressing in of the band edge on the end face of the workpiece plate downwards or to tilt.

Advantageously, it is provided in the gluing machine that it provides a preparation arrangement of the adhesive-applying device for providing a volume of the adhesive to an adhesive outlet in a suitable for wearing the adhesive on the band edge liquid state depending on at least one adjustable and / or sensory detectable Parameter.

It is expediently provided in the gluing machine that a preparation arrangement of the glue application device for providing the adhesive in a liquid state suitable for applying the adhesive to the gluing strip is arranged in an upper region of the machine housing so that the preparation arrangement is in a position of use when the gluing machine is guided along the workpiece plate, is arranged above a tape outlet of the tape guide means for guiding the Umleimerbands to the end face of a workpiece plate, and that a glue channel for the liquid adhesive from the preparation arrangement with respect to the use position down in the direction of the tape guide means to an adhesive outlet , The provisioning device is preferably arranged in the position of use of the gluing machine below the preparation arrangement.

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.

A gluing machine 10 for gluing a band Umleimands U to a workpiece plate W is, for example, a connection cable 11 and / or an energy storage, not shown, for. a battery, supplied 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 lid 27 is for example with a pivot bearing 29 movably mounted on a top side 26 providing wall 30 of the upper housing part 22 between a closing a receiving opening 31 of the staging area 28 closing position and this releasing open position pivotally. Preferably, a spring arrangement, for example comprising a leg spring, is provided, which loads the cover 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 banding band U into the band guiding device 50, namely a band inlet 54, so that the banding band U is guided along a guideway 55 and leaves the guideway 55 in the area of the starting roller 52 at a band outlet 56, so to speak. 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 may optionally, for example, at the Underside of the cover plate 38 further guide components to guide the Umleimerbands U be provided, but need not.

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 fixed relative to the machine housing 20, i. the upper narrow side U2 of the bandage U has a constant height position with respect to a height direction H of the machine housing 20.

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 readily possible. 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 guided on spaced columns or guide rods 69 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 drive roller configured as an input roller 51 is in driving engagement with the Umleimerband U, if this in the Guide groove 65 is received and the drive roller or input roller 51 is opposite.

The input roller 51 and the output roller 52 are configured here as rollers. The input roller 51 and the output roller 52 have on their outer circumference expediently an elastic surface and / or a surface with a relatively high coefficient of friction, 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 row arrangement of the outlet openings 73 corresponds to a maximum possible width B of the band Umleimands U so that this optionally wetted or provided over its entire width B with adhesive K. can be. 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 can be linearly reciprocated along an adjustment axis 75 within the channel body 72 such that a channel portion 76 of the valve member 74 faces a number of adjacent outlet openings 73 corresponding to a width B of the respective band 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 closed by an actuator 141 between an open position and a the exhaust ports 73 Closed position adjustable, eg 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 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 stepper motor, or knows a control activating the servomotor 141, as the current closing parameters 145 and / or adhesive thickness value 143 depend on the control of the servomotor 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 the respective height position of the Guide body 62 with respect to the height direction H can detect. 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 preparation 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 accommodated 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 introduced piece by piece into the staging area 28 be inserted. 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 in turn, fixed in the upper housing part 22 is fixed, 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 may be used for cooling purposes, for example of metal, e.g. Aluminum, be. An insulating ring or insulator body 96 disposed in front of the cover body for heating 90 expediently consists of plastic or another thermally 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. But it is already noticed that, of course, a preparation or preparation of the Adhesive K in the housing base 21 would also be possible 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 along the workpiece guide surface 100 along the surface O, at the same time adhering the gluing tape U to the end surface 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. Based on Boom fastener 108, the boom 101 can be releasably secured 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 retaining projections engaging with the retaining receptacles 110 109, but also on the support surfaces 112, 113 is intercepted.

The boom 101 is also still locked to the machine housing 20 by means of a latch assembly 114 and also still clamped, 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 be pressed, which puts the gluing machine 10 in the correct working mode, as it were. that the edge band 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, i. the pressure roller or output roller 52, as it were, rolls on the bandage U already glued to the end surface S and pushes the gluing machine 10 gluing machine 10 forwards in the direction of the still unprocessed area of the work piece W. With the feed switch 18, a feed rate 165 can also be selected be, 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 inclined, without this seriously affecting the function of the gluing machine. 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 that, of course, not on the design principle of the gluing machine 10 according to the drawing It would also work in conjunction with, for example, a gluer that conditions the adhesive in a lower housing part that does not have other drive principles or even the intelligent glue preparation control system described later.

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 port 12 or as an alternative to it, it would also be possible for a fan 14, for example, to have one Airflow from the adhesive outlet 71 or from any other area of the gluing machine 10 to be vented away, for example, in the direction of the filter 13 or at least away from the operator, who is breathing air above the gluing machine 10 during operation thereof.

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 can grasp the tape roll C from radially outward. 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 on the bottom wall 204 and / or inside of the peripheral wall 205th at least one sliding projection 213, for example, sliding ribs or the like, are provided, 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. By way of the bearing device 240, the provision device 200 is, for example, for positioning with respect to the belt inlet 54 slidingly and / or pivotally mounted 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 laterally supported 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 is provided by a locking device 230 lockable. The locking device 230 comprises a latch 231, for example pivotally mounted on the support body 201, which can be brought into engagement and out of engagement with the guide body 62 of the width adjustment device 60. 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 operator 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 preparation space 28 etc. Further, an adhesive amount indicator 157 may be provided, the current on indicates the Umleimand U applied 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 effluent from the adhesive outlet 71 liquid adhesive K. For this purpose, for example, 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 is shown with only one output, namely a worm 130, drives a worm wheel 131 at. 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 delivery member 82 / the piston 83 in the drawing travels to the left, i.e., to the left. away from the heater 90, so that as much space as possible for introducing the adhesive pieces P is available. 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 runs back a predetermined distance, so that the arrangement so far relaxed is that the adhesive 90 when heating the heater can expand by a certain amount and exerts no excessive pressure on the closing valve, at least in the direction of the adhesive outlet 71, 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 control device 160 is, for example, a component of the preparation arrangement 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 this manner in dependence on at least one adjustable and / or sensor-detectable parameter in such a way, that they provide the volume of the adhesive K for the application to the adhesive outlet 71 in a suitable liquid state for application to the Umleimerband U in the exactest possible size. 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 be sent to the controller 160, e.g. also be known by having a servomotor (not shown), e.g. 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 by the exact startup procedure described above after the insertion of adhesive pieces P in the staging space 28 and the exact position of the motor 129, 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 gives the Control device 160 on the control interface 150 as range indicator 152 off.
