Description

The invention relates to a device for dispensing an adhesive tape with a housing in which a supply reel for the adhesive tape, a device for removing the adhesive tape from the supply reel and a cutting device for cutting off the removed piece of adhesive tape are accommodated.

Devices which deliver an adhesive-coated adhesive tape to a substrate are known, for example from DE-A1-3 109 735, DE-A1-2 801 540 and EP-A-0 092 187. All these known devices make it possible to glue the tape onto a substrate, such as sheets of paper or an envelope, for which purpose the device is pulled over the substrate in question, the adhesive tape is released, and finally the peeled-off piece of tape is cut off.

Although the known devices mentioned allow the application of an adhesive tape to a base, the tape being cut off at the end of the application process, they are not able, if desired, to also dispense an adhesive tape section of a certain length to the user without the device being opened a document must be moved. If the user nevertheless wants to remove a section of tape from them, he must, if this is possible at all, in a cumbersome and cumbersome manner grasp the end of the tape present at the outlet of the device with his fingers, pull the tape out of the device, thereby loosening the supply reel if necessary and in the end effect the cutting process in a suitable manner. Since these devices are not set up for such a removal of adhesive tape, this is - if at all possible - not only complicated and cumbersome, but there is also the risk that if the user is not sufficiently careful, the cutting process can lead to injuries to the fingers.

Proceeding from this, the invention has for its object to improve a device of the type mentioned so that it allows the delivery of tape pieces of predetermined length for manual removal by the user with a comparatively simple structure and ease of use.

According to the invention, this object is achieved in a device of the type mentioned at the outset in that a lever which is spring-biased into a starting position projecting from the housing and is pivotable against the housing is provided for actuating the device for pulling off the adhesive tape and the cutting device, which starts when it is pivoted from its initial position, the device for pulling off the adhesive tape over a first swivel area and the cutting device in the subsequent remaining swivel area.

The device according to the invention represents a handy dispensing device for a tape provided with adhesive, which is equally suitable for direct tape application on a support (with a movement of the device along the support) as well as for dispensing individual pieces of tape that can be done by hand Device easily removed and then glued to a substrate. In the case of direct tape application to a substrate, the lever is pressed in by the operator only within its first pivoting range and the movement of the housing along the substrate is carried out for as long as is necessary for the desired application length. At the end of the application process, the lever is also pivoted along its subsequent second pivoting area by pressing the housing until the lever stops, thereby activating the cutting device through which the desired band section takes place.

However, if it is desired to dispense individual pieces of tape from the device (and not a direct application of adhesive tape to a substrate), the device according to the invention is held up with the lever protruding from the housing, i.e. placed the back of it on a surface (or in your hand), and then manually pushed the lever into the housing. A certain length of tape is unwound from the supply reel (along the first lever pivoting area). If the lever is pressed in even beyond the second pivoting area, the section of this unwound length of tape is carried out, so that a tape of this length can subsequently be removed. If the user wants a longer tape, there is also the possibility for him not to press the lever all the way in, but to press it several times ("pump") within the first swiveling range, in order to activate the tape pulling device again and again, which leads to unwinding increasingly longer tape that, when the desired tape length is reached, can finally be cut off by fully pressing the lever.

Thus, the device according to the invention proves to be particularly versatile in comparison to the known devices, the delivery of individual pieces of tape from the device for manual removal by the user also taking place in a particularly convenient form and also virtually no risk of contamination of the hand of the user. This is because the user only needs to grip the tape hanging out of the device with his fingers at a suitable point in order to then pull it in to be able to glue on a substrate as desired.

In a particularly preferred embodiment of the invention, the first pivoting area along which the adhesive tape is pulled off the supply spool is significantly larger than the remaining, second pivoting area in which the cutting device is activated, the first pivoting area particularly preferably extending over an angular range , which is 10% to 20% of the total pivoting range of the lever. As a result, a sufficiently large first pivoting area is created in a manner which is particularly favorable for use, which is followed by a second, only relatively short pivoting area, in which the cutting then takes place. When the adhesive tape is applied directly to a substrate, the risk that the user accidentally gets from the first pivoting area into the second pivoting area and thereby undesirably triggers a detachment of the adhesive tape is largely avoided, all the more so since the direct cutting process itself only at the end of the second swiveling area is carried out, while over the second swiveling area only a corresponding swiveling of the cutting device from an inactive starting position into the active cutting position (at the end of which the cut is made) or a tension of a spring which finally brings about the cutting process at the end of the pressing in of the lever he follows.

Particularly advantageously, the invention further provides that the position of the lever within the second swiveling area covers the cutting devices in such a way that they are inaccessible from the outside, thereby reducing the risk of undesired injury e.g. the finger of the user, such as a child, is effectively prevented on the cutting device.

The manual removal of cut pieces of adhesive tape from the device according to the invention can be accomplished particularly conveniently in that the lever at the end of the second pivoting area can be pressed against one end of the cut piece of tape on its adhesive-coated side, as a result of which the end of the tape adheres to the lever and is then folded out of the lever in its starting position, the cut piece of tape hangs on the lever end that is folded out, so that it can then be removed particularly conveniently and in particular with one hand by the user.

A further advantageous embodiment of the device according to the invention also consists in that the housing is provided with a movable bow roller, via which the adhesive tape emerging from the housing can be guided and by means of which this can be pressed against a substrate when the housing is turned over, the bow roller from a starting position, in which it is pretensioned by means of a spring element, can be displaced under pressure into a working position and, when it runs back into its starting position, triggers the actuation of the cutting device. As a result, when using the device, the operation of the cutting device can be carried out manually in a particularly simple manner, by relieving the device of pressure only at the end of the application process, as a result of which the bow roller, due to its spring preload, runs back from the working position towards the starting position and thereby already Cutting device is activated without this requiring an additional complete pushing in of the actuating lever.

A very particularly preferred embodiment of the invention is that blocking means are provided in the housing which block the lever from pivoting back into its starting position as long as the cutting device is actuated, i.e. as long as the lever is in its second swivel area adjoining the first swivel area. This enables a particularly simple use of the overall device. Because the user must e.g. To apply the tape, insert the lever only slightly over the first pivoting area into the second pivoting area, after which the lever is locked in position, i.e. does not run out of the housing again, which is particularly advantageous when applying adhesive tape directly to a substrate. The cutting device can then be triggered particularly simply in the manner already specified by the arrangement of the spring-loaded bow roller. But even if such a bow roller should not be provided, at the end of the application section the housing can be pressed down against the base, the lever can still be pivoted in completely over the second pivoting area and the cutting device can thereby be activated. In addition, the provision of the specified blocking agents during manual removal can also ensure that the belt is no longer transported while the cutting device is activated.

A particularly compact embodiment of the device according to the invention can preferably be achieved in that an intermediate wall is provided in the housing, on one side of which the lever, the supply roll and the device for pulling off the adhesive tape are arranged, while on the other side coupling and transmission means are provided are, via which the movement of the lever for actuating the device for removing the adhesive tape and the Cutting device is transferable.

The lever is preferably firmly connected to one or more racks, which are parts of the coupling and transmission means. Advantageously, the first rack for actuating the device for pulling off the adhesive tape and the second rack for actuating the cutting device are formed, while the third rack is part of the blocking means. It is furthermore particularly preferred if a rack is designed to be resilient in the direction of engagement and is provided with oblique, approximately sawtooth-like teeth, whereby the drive movement of the lever on a toothing meshing with these oblique teeth can only be transmitted in one pivoting direction of the lever, while in the In the opposite direction, the teeth of the toothed rack disengage from the toothing by thereby disengaging the toothed rack due to its resilient design.

In another preferred development of the device according to the invention, the device for pulling off the adhesive tape from the supply reel has a first roll with a corrugated surface, a second roll with also a corrugated surface, the rotational speed of which when the device for pulling off the adhesive tape is actuated is lower than that of the first corrugated roll and the corrugated surface of which faces the adhesive-coated front side of the adhesive tape, and an intermediate roller, the outer circumference of which protrudes into a circumferential groove on the corrugated surface of the first and / or the second roller. With this arrangement it is achieved that the adhesive tape is slightly bent or folded in the area covered by the intermediate roller, which acts as a guide roller, during its transport over the corrugated surfaces of the two rollers, in order to stiffen it temporarily during transport to the outside . The greater rotational speed of the first roller compared to the second roller also prevents the adhesive tape from sticking to the rollers and thereby undesirably moving between the rollers in the wrong direction.

In a further advantageous embodiment of the invention, the supply roll is held by the adhesive tape (with associated strip guide devices) in an interchangeable cassette which can be inserted into the housing, which results in a possibility for simple and rapid replacement of the strip roll. The exchangeable cassette is preferably equipped with a device by means of which the free end of the adhesive tape can be fed to the device for peeling off the adhesive tape when the exchangeable cassette is inserted into the housing.

Another advantageous development of the device according to the invention also consists in the fact that a gear meshing with the resiliently designed toothed rack has a torsional resistance which is sufficient when the lever returns to bring the teeth of the toothed rack out of engagement with it.

In the device according to the invention, the entire transmission mechanism is elegant and simple and creates an overall construction in the form of a ratchet construction with a simple return.

1 and 2 show a first embodiment of a device 1 for dispensing a one-sided adhesive-coated adhesive tape B. The device 1 is shown above a holder 2, into which it is inserted.

The device 1 can also be used for the continuous unrolling of the adhesive-coated adhesive tape: FIG. 2 shows the device in this position of use, with which an adhesive tape B 'is used to glue the butt joint between two abutting documents S ₁ and S ₂ . In this case, as shown in FIG. 2, the device is taken from the holder 2 into the hand H (FIG. 2) and inserted in the “reverse” position to FIG. 1. In this case, the adhesive tape B 'is unrolled from the supply roll R, which is fixed to the housing, onto the two bases S ₁ and S ₂ and glued simultaneously.

The device 1 shown in FIGS. 1 and 2 is provided with an actuating lever 3 which, in the position of use shown in FIG. 1, when pressed in a piece of adhesive tape B of the desired (preset) or, if desired and achieved by multiple pumping, also by longer length.

As will become apparent from the following explanations, a piece of adhesive tape B 'is cut off when the lever 3 is fully pressed in. By "pumping" operation of the lever 3, on the other hand, an increasingly longer piece of tape is obtained from the device 1.

A stop pin 48 (FIG. 4) movable in a slot determines the stop of the lever 3; this is biased by a spring 49 in its outwardly open starting position.

In the position of use of the device 1 shown in FIG. 2, the lever 3 (not shown in detail in FIG. 2) is arranged on the underside of the device 1 and pressed into the housing 4 of the device. The desired tape length is rolled off via a bow roller 5 at the front end of the housing 4, over which the adhesive tape B 'runs, by means of which it can be pressed against the base and the axis of which is displaceably mounted within the lateral longitudinal slots 15. In the use position shown in Fig. 2, the lever 3 can be transferred to a second angular position in which it is blocked, i.e. Despite its bias by the spring 49, it does not run any further to the outside, so that it does not protrude undesirably against the support in the position of use shown in FIG. 2. In this second stop position, the lever protrudes less far from the housing 4 and does not interfere with the application.

For the sake of clarity, the embodiments shown in FIGS. 1 and 2 are shown without a corresponding cover housing, which of course usually surrounds the device 1.

In Fig. 1 are also drawn with IV-IV and V-V the course of the cuts, in which the representations of Fig. 4 (section IV-IV) and Figs. 5 to 10 (section V-V) are shown.

As shown in FIG. 3, the rotary movement of the lever 3 is transmitted to the take-off device 7 via transmission devices 6 located on its pivot axis 10 in the form of toothed racks 12, 13, 14 in the form of a sector of a circle, the toothed rollers 8, 9 meshing with one another with different diameters having.

The lever is rotatably supported by its axis 10 (FIGS. 3 and 4) in an intermediate wall 11 of the housing 4, the lever 3 on one side of the intermediate wall 11 and the transmission device 6 in the form of the toothed rods 12, 13, 14 are attached on the other side of the intermediate wall 11.

The first toothed rack 12 has an oblique, zigzag-shaped toothing which meshes with toothed wheels 16, 17, which in turn are arranged on the axes of the rollers 8, 9 and also have a corresponding oblique toothing. When the rollers 8, 9 rotate, the belt B is transported over the surfaces of these rollers 8, 9, which are corrugated. 3, a guide roller 18 is provided which projects into a circumferential groove of the rollers 8, 9, as shown in FIG. 3. The band B, which is also guided along this guide roller 18, is slightly bent or folded at the points at which it is pressed somewhat into the circumferential groove of the roller 8, 9 in question, and is thereby removed during transport to the outside ( temporarily) somewhat stiffened.

The roller 9 is provided with a somewhat smaller diameter than the roller 8, the transmission ratio effective in the device ensuring that the speed on the corrugated outer circumference of the roller 8 is greater than that on the corrugated outer circumference of the roller 9. It is thereby achieved that the adhesive tape B, the adhesive-coated side of which lies towards the roller 9, can be easily moved along this and can prevent the adhesive tape B from sticking to the roller 9 and then being able to be pulled in between the rollers 8 and 9 .

The rack 12 is preferably movable at least somewhat about a hinge axis 19, since the largely circular segment 20 which forms the rack 12 is provided with a cam 21 projecting from the side. The segment 20 is thereby and by the game 24 formed in it compared to a second segment 22 which the second rack 13 carries, and a third segment 23, which carries the third rack 14, relatively pivotable. Accordingly, if a longer piece of adhesive tape is to be unwound, the lever 3 can be moved before the tape is cut off by repeated pumping, ie moving the lever up and then down, etc., until the desired tape length is reached. This is possible because the toothed rack 12 is able to detach itself from the (oblique) teeth of the toothed wheels 16 and 17 during the upward movement.

The representation of FIGS. 4 and 5 schematically show this “pumping” by means of the actuation arrows shown on the lever, wherein in FIG. 4 a pushing of the lever downward and in FIG. 5 a running up of the lever are shown. After a certain pivoting of the lever 3, the rack 13 engages in the gear 31 assigned to it (see FIG. 6), to which a tension spring 32 is also eccentrically fastened, which in turn is connected to the housing by means of a pin 33.

After the toothed rack 13 and the toothed wheel 31 have been moved over a certain pivoting range (FIG. 7), a nose 36, which locks the third toothed rack 14, of a rotatably mounted locking element 37, which also locks against a pin 39 by means of a leaf spring 38 attached to it supported on the housing, the lever 3 so that an upward movement, ie a return movement in its starting position, even under the action of the biasing spring 49 is no longer possible. At the same time, the tension spring 32 is kept under tension. The gear 31 can, as shown in FIGS. 7 and 8, run over the toothing of a pinion 41, which is possible because this is resilient in one direction against the toothing with the aid of a spring element 46 bent around pins 44 and 45 of the gear 31 is biased.

By further pressing the lever 3 (see FIG. 9), an unlocking element 51 is finally actuated, which releases a stop 52 from another stop 53, which is located on a wheel 55 provided with two wing members 54. As shown in FIG. 8 in particular, the wings 54 actuate a partial element 56 of a knife holder 57 (cf. also FIG. 3). This knife holder 57 carries a knife 58 and is resiliently fastened by means of a leaf spring 59.

After unlocking of the wings 54, the knife moves towards the band B at high speed due to the prestressed spring and strikes through it. This is shown in Fig. 10. Specifically, after unlocking, the stored force of the tension spring 32 is transmitted to the knife 58 via the toothed wheel 31, the pinion 41 and the wing members 54 (cf. FIG. 9).

When the wheel 55 has made half a turn, a locking element 37 is released via a retaining pin 61 on the wheel 31 (see FIG. 6), as a result of which the third toothed rack 14 freewheels and the lever 3 acts due to the spring 49 acting on it Preload moved up to its starting position. The racks 12 and 13 are kept clear by a stop 38 and a pin 21.

The length of the lever 3 is preferably such that when the lever springs back, a piece of tape B remains stuck to it, as shown in FIG. 1.

When the dispensing device is used in the position of use shown in FIG. 2, ie when the lever 3 is in its retracted position, the unlocking element 51 is pressed in. The nose wheel 5 is pressed onto the surface S ₁ or S ₂ (with the interposition of the belt B ') and the belt B' is unrolled. Under pressure, the nose wheel 5 is moved against spring preload in a slot and the wheel 55 is blocked by a stop 60 (FIG. 8). When the load is released, this lock is released, so that the tape B can be cut.

• Diese Ausführungsform enthält eine mit Transporträdern 76 versehene Kassette 75, in der sich eine Vorratsrolle befindet (nicht abgebildet). Die Vorrichtung 74 ist hier mit zweiten Transporträdern 77, einem Zwischenrad 78, Schneidemittel 79 sowie einem Bugrad 80 entsprechend der in Fig. 11 dargestellten schematisierten Anordnung versehen.

11 shows a further embodiment for the device:

• This embodiment includes a cassette 75 provided with transport wheels 76, in which a supply roll is located (not shown). The device 74 is here provided with second transport wheels 77, an intermediate wheel 78, cutting means 79 and a nose wheel 80 in accordance with the schematic arrangement shown in FIG. 11.

Between the first and second transport wheels 76 and 77 there is a pinion 81 for transmitting the movement of the second transport wheels 77 (which are driven by the lever 3 in a manner not shown) to the first transport wheels 76 with the same direction of rotation. The cassette 75 is preferably provided with a spring-loaded lever 82 which carries an arm 83 extending transversely to it for the unrolling of the tape from the supply roll fixed to the housing after the cassette 75 has been inserted into the overall device 74, so that the tape with the lever between the Transport rollers 76 and 77 past the nose wheel 80 until it can be transported to the outside of the device 74. When the cassette 75 is inserted, the lever 82 is pushed past a stop 84 and a wheel 85, as a result of which the cross arm 83 rolls off the tape and a loose loop is formed in the cassette 75.

In addition to the training shown, there are also other simplifications for the transfer movement of the lever possible.

Fig. 12 shows in a basic representation such a different embodiment for a simplified transmission of the lever movements. In this case, a further spring element 95 is formed on a pivoting segment 91 with a toothing 92 for locking, which also has a toothing (rack) 93 , which engages in the toothing 94 of a second transmission element, which in turn is also provided with a toothed rack 96 which is connected to it in a resilient manner and which engages in a toothed wheel 97 with which a desired transport can be carried out.

The part 95 is additionally connected to a further toothed rack, which, however, is not shown in FIG. 12.
