Description

[0001] The present invention relates to a removal device for removing stickers from carrier substrates and a method for this purpose. State of the art

[0002] In practice, sticker dispensers, usually spring-loaded or motorized, are frequently used. These devices are generally heavy and restrict the user's mobility. Such dispensers are often used in warehouses to mark removed goods or label them for shipping. Especially in large warehouses, these dispensers prove to be disadvantageous, as the user must always return to the dispenser with the selected item to remove the necessary sticker, or else make a double trip, first retrieving the label from the dispenser and then carrying it to the item.

[0003] Furthermore, it is particularly disadvantageous that the empty, detached carrier material lies disorderly on the floor in long strips, thus creating an increased hazard for the user.

[0004] The empty carrier material can conceal or even pose hazards, especially if the user steps on the carrier material, which is usually designed to promote slipping, slips and falls.

[0005] Furthermore, empty backing material poses a fire hazard and reduces order and cleanliness in the workplace. In open areas, such as factory yards, lying around and easily blown away backing paper is also a source of environmental pollution. Task

[0006] Therefore, the present invention aims to provide a device that offers increased safety for the user, increases their productivity, and simultaneously enables the required mobility and speed in the labeling process, in which goods are labelled with stickers. Solution

[0007] These problems are solved by the subject matter of claim 1 and the method claim 8.

[0008] The core idea of ​​the present invention is to provide a removal device for removing stickers from carrier substrates, which has at least one basic housing through which at least one sticker-carrier substrate unit and / or parts of the at least one sticker-carrier substrate unit can be guided on predetermined movement paths, wherein the at least one sticker-carrier substrate unit can be guided via at least one first guide path to at least one removal unit, at which the sticker and carrier substrate are separated from each other, and wherein the removal device further has at least one multi-part rotating element for receiving an empty carrier substrate, which can be fed to the multi-part rotating element via the further movement path, wherein the rotating element is designed as a split shaft.

[0009] The term "sticker" can refer to any type of printed product with at least one self-adhesive surface. This self-adhesive surface is attached to a backing substrate for transport and is removable from it. Once a sticker is removed from the backing substrate, the empty substrate remains, and the sticker can be reused. Examples of stickers include labels, and stickers, although labels are advantageously used for the removal device described here. The removal device can therefore also be called a label removal device.

[0010] The device described here offers the advantages of a compact design that allows for both quick and easy removal of the stickers, while simultaneously retaining the empty backing material. The removal device thus features an integrated winding mechanism for the empty backing material. This integrated winding is made particularly effective by the split shaft. This prevents the empty backing material from being scattered on the floor, significantly reducing a potential hazard. The split shaft not only enables efficient winding of the empty backing material but also allows for particularly easy removal of the material once all the stickers have been used and the backing material needs to be removed from the housing.

[0011] The base housing forms the core unit of the described removal device, providing overall stability. Furthermore, the base housing offers sufficient storage space to efficiently store the empty backing material in a rolled-up state until all the stickers are used.

[0012] The rotating element for holding the empty backing substrate is designed as a split shaft. This is advantageous because the at least one sticker-backing substrate unit can be at least partially fixed by the split shaft. The fixing of the at least one sticker-backing substrate unit is advantageously achieved with its free distal end. At the same time, the split shaft acts as a reservoir, storing the empty backing substrate after the sticker has been removed. This prevents unwanted contamination of the work area and significantly reduces potential hazards for the user.

[0013] Furthermore, the split shaft proves particularly advantageous when all the stickers have been used up and the empty carrier substrate, tightly wound onto the split shaft, needs to be disposed of. By designing the rotating element as a split shaft, it is now possible for the first time to remove only a section of the shaft, thereby releasing the tension on the rolled-up carrier substrate and allowing for quick and efficient disposal.

[0014] The release unit, which is at least partially integrated into or attached to the base housing, is, in its simplest form, edge-like. The sticker-backing substrate unit is guided over at least one edge, so that the sticker is released by the backing substrate being guided at an acute angle along guide paths towards the rotating element. The released sticker can then be removed directly from the edge or through a designated opening in the base housing, while the empty backing substrate is wound up by the rotating element.

[0015] Further advantageous embodiments are described in the dependent claims.

[0016] In a further advantageous embodiment, the at least one sticker carrier substrate unit can be inserted into the base housing from the outside and / or the at least one sticker carrier substrate unit is arranged completely inside the base housing.

[0017] When feeding at least one sticker carrier substrate unit into the housing from the outside, the housing can be positioned in a stationary position. The sticker carrier substrate units are fed from the outside into the interior of the housing. To ensure particularly clean and safe removal of the stickers from the carrier substrate, the units are guided along predefined movement paths within the housing, allowing the desired stickers to be extracted and removed from the housing via a release unit. Furthermore, the empty carrier substrate is advantageously stored via the rotating element, which is designed as a split shaft. This ensures a clean and safe working environment.

[0018] This is of course not to be understood as a limitation, so it is also conceivable that at least one sticker carrier substrate unit is designed as a sticker dispenser unit, which is arranged within the main housing. This creates a mobile unit that can be conveniently taken along to the goods, since everything is stored compactly within the main housing.

[0019] The sticker dispenser unit can be understood as the carrier substrate with stickers arranged on it. Advantageously, the device described here for the first time uses numerous sticker carrier substrate units, which in the simplest case are in the form of a strip. The strip can, for example, be folded, particularly accordion-style, or provided on a roll for use.

[0020] Depending on the intended use, whether stationary or mobile, the sticker dispenser unit is then fed in accordingly. When fed from the outside, the release mechanism is used in a stationary position. If, however, the release mechanism is to be used as a mobile unit, the entire sticker dispenser unit is already inserted into the base housing.

[0021] In a further advantageous embodiment, the base housing for receiving the sticker dispenser unit has a designated area for the sticker dispenser unit. The sticker dispenser unit can be positioned in this area before use, for example, by being inserted. Advantageously, the sticker dispenser unit is loosely arranged in this area. This is beneficial for particularly effortless operation of the release mechanism and effortless sticker removal. Alternatively, in a stationary design of the release mechanism, the sticker backing substrate units can be inserted into the interior of the base housing through this area, so that the subsequent arrangement of the sticker backing substrate units within the base housing remains the same.

[0022] Furthermore, a combination of both is also conceivable. Such a removal device can then be used both stationary and mobile. This creates greater application flexibility and saves on acquisition costs. For example, for feeding the sticker dispenser unit in stationary use, an opening can be provided in the base housing in the sticker dispenser unit area, through which at least one sticker backing substrate unit can be inserted into the interior of the base housing. Advantageously, the opening is located in the lower third of the overall height of the base housing. This is beneficial because it utilizes comparable movement paths within the base housing as in mobile use. Thus, safe and easy removal of the stickers and storage of the empty backing substrate are always ensured, regardless of whether the removal device is designed or used in a stationary or mobile configuration.

[0023] From this sticker dispenser unit area, the sticker dispenser unit, i.e., the numerous stickers on a carrier substrate, can then be guided along the predetermined guide paths over the release unit within the base housing, so that the free end of the sticker dispenser unit is guided between the split shaft of the rotating element and is detachably fixed in between.

[0024] In a further advantageous embodiment, the rotating element designed as a split shaft has at least two sections which, in a state of use, at least partially share a common contact surface.

[0025] In this context, "in operating condition" refers to the state in which the sticker dispenser unit is ready for use within the basic housing, advantageously guided along the movement paths, and with its free distal end positioned, at least partially, between the two shaft sections. This applies to both mobile and stationary use.

[0026] Particularly advantageous is the fact that the wave sections are clamped against each other or with each other in the state of use by means of a force-locking and / or form-locking connection, so that the free distal end of the sticker dispenser unit, which in the simplest case is designed as a roll or folded stack, is arranged between the wave sections and is clamped by them by means of a force-locking and / or form-locking connection.

[0027] Furthermore, it is conceivable that the two shaft sections, in the state of use, may form a positive connection as an alternative or supplement to the force-fit connection.

[0028] The force exerted by the wave segments on the interposed sticker dispenser unit is greater than the force required to remove the stickers. This ensures that, through rotation of the rotating element—more precisely, through rotation of the clamped wave segments—the sticker backing substrate unit unwinds from the sticker dispenser unit. Simultaneously, it ensures that the respective sticker is detached from the backing substrate via the release unit, and that the tensile force generated by the rotation of the fixed wave segments is sufficient to guide the empty backing substrate around the wave segments, for example, to roll the empty backing substrate around the rotating wave segments. The free distal end of the sticker dispenser unit can still be fitted with a sticker.However, it is also conceivable that, for improved winding behavior, the first stickers are manually removed from the carrier substrate and only the empty carrier substrate is removably fixed between the two wave sections.

[0029] The originally distal end of the sticker dispenser unit is clamped between the wave sections throughout the entire winding process of the empty carrier substrate.

[0030] It has proven advantageous if the two sections, which at least partially form a common contact surface in the operating state, have a substantially flat profile. In the simplest case, this means that the facing sections and / or the contact surfaces are free of depressions and / or curves in the operating state. In this embodiment, it has proven advantageous if at least the areas that form a common contact surface in the operating state and / or the areas between which the empty support substrate is fixed are made of PLA plastic. The PLA plastic can be injection-molded and / or applied as a surface modification.

[0031] Furthermore, it has proven advantageous if at least one of the facing surfaces of the wave sections has at least one area of ​​surface modification. This is beneficial because it significantly improves the adhesive properties of the sticker dispenser unit and / or the empty carrier substrate between the two wave sections.

[0032] Surface modification can be achieved, for example, through coating, rubberizing, or roughening. Depending on the size and expected forces, both surfaces facing each other in the operating state can also be surface-modified, for example, completely or partially coated, rubberized, or roughened.

[0033] It has proven particularly advantageous if the two surfaces facing each other in the service state, as an alternative or supplement to coating, rubberizing, or roughening, have a predetermined number of gradations as a surface modification. The number of gradations, as well as their geometry and size, are variable and can be individually adapted depending on the properties of the substrate used.

[0034] Furthermore, it is conceivable to design the steps of one surface at right angles to each other. Additionally, the steps of the second wave section are then designed to be complementary to this, thus ensuring a reliable clamping function for the sticker dispenser unit or empty carrier substrate positioned between them during use.

[0035] This is of course not to be understood as limiting, so it is also conceivable that the angles of the steps to each other are not equal to 90°.

[0036] Furthermore, all steps can have the same geometric shape and orientation. For example, a force-fit and / or form-fit connection of the shaft sections can be provided. This can be, for example, a stepped shape, inclined shape, pyramid shape, prism shape, ellipsoid shape, and / or combinations thereof. In every case of steps, both contact surfaces are designed to be complementary to each other, so that the clamping function is ensured at all times. Additionally, it is also conceivable to design one contact surface with rubber and the second contact surface with steps. By releasably fixing the two shaft sections to each other, the steps are guided against the rubber and at least partially pressed into it. The desired clamping effect can also be generated in this way. However, it is conceivable that the steps of a shaft section differ from each other.For example, a force-fit and / or form-fit connection of the shaft sections can be provided. This can be, for example, a stepped shape, inclined shape, pyramid shape, prism shape, ellipsoid shape and / or combinations thereof.

[0037] In addition to the regular stepped shape, the pyramidal shape has also proven advantageous, as it likewise provides a reliable clamping function. In this case, the pyramidal steps of the two surfaces of the shaft sections are offset from each other.

[0038] The steps can be arranged in single, double, or multiple rows, which is advantageous. This further improves the clamping function, especially if the steps are staggered within each row.

[0039] As already explained above, the wave sections on the two facing surfaces can also have a combination of steps and / or surface modifications and / or material modifications, so that a particularly advantageous positive locking and / or force locking connection can be formed.

[0040] The overall shaft, formed by the two shaft sections, is advantageously divided at an angle. Particularly advantageous is the wedge shape of each of the two shaft sections. This allows for the effortless removal of a shaft section when the empty carrier substrate needs to be disposed of. The wedge shape facilitates effortless removal, especially pulling a shaft section out of the base housing.

[0041] It has proven advantageous that the inclined surface created by the wedge shape has an angle of 0.5 to 10°. This allows for particularly secure clamping of the empty support substrate. In a particularly advantageous embodiment, the inclined angle is 4° with a longitudinal extent of the shaft sections of 70 mm. If the longitudinal extent of the shaft sections is increased, the inclined angle decreases accordingly.

[0042] In a further advantageous embodiment, the rotating element is mounted to rotate about a longitudinal axis via at least one rotation mechanism arranged outside the base housing. This is advantageous because the release device can thereby be operated with one hand. The mechanism can thus be operated easily and quickly with one hand, so that the rotating element is rotated by an angle that can be predetermined by the user.

[0043] This pre-set rotation advantageously separates exactly one sticker from the backing substrate via the release unit. The sticker can then be removed and processed directly. The empty backing substrate, i.e., the substrate without the sticker already removed, is wrapped around the rotating element, thus saving space during storage.

[0044] The longitudinal direction is advantageously understood to be the direction in which the element of rotation has its greatest geometric extent. For this purpose, the longitudinal axis around which the element of rotation can rotate is also defined.

[0045] This is of course not to be understood as a limitation, so it is also conceivable to operate the device with both hands.

[0046] In another advantageous embodiment, the two shaft sections are symmetrical to each other. This is particularly advantageous in the manufacture of the shaft sections, as they can thus be produced cost-effectively. In the simplest case, both shaft sections are identical to each other.

[0047] A wedge shape for the individual wave section has proven particularly advantageous, as it allows the wound-up empty carrier substrate to be removed with minimal effort.

[0048] In a further advantageous embodiment, each shaft section has at least one recess towards its first free distal end. Furthermore, each section has a further recess spaced apart from the first recess. The recesses are particularly advantageously positioned such that, in the operating state, the first recess of the first shaft section forms a continuous groove with the second recess of the second shaft section and / or the second recess of the first shaft section forms a continuous groove with the first recess of the second shaft section. These grooves can, for example, be designed as slots.

[0049] In the simplest case, the recesses of the shaft sections each form a continuous groove. This is advantageous for clamping the shaft sections to each other and / or to the base housing.

[0050] In a further advantageous embodiment, each shaft section has a termination element towards its second distal end. The termination element is detachably arranged from the respective shaft section and serves to fix and retain the respective shaft section within the device. This is, of course, not to be understood as a limitation, so it is also conceivable that the respective shaft section and its associated termination element are formed as a single piece. This can be achieved, for example, using injection molding. The termination element can therefore also be understood as a positioning aid, providing a stop to determine how far the respective shaft section can be inserted into the base housing until it is functionally positioned.

[0051] It is particularly advantageous to arrange the end element externally on, or at least partially attached to, the base housing. Depending on the design, it is also conceivable that the end element can be inserted and / or passed through an opening in the base housing, at least partially.

[0052] In the separate version, it is possible to couple the respective end element with the associated shaft section, advantageously directly by connecting, for example by snapping, pressing, screwing, gluing or clicking, or to manufacture as a single-piece version.

[0053] In a particularly smooth-running design, the end element is arranged on the outside of the base housing and holds the respective shaft section, which is located inside the base housing, for example, via a recess. Advantageously, the recess of the end element is D-shaped. This special shape allows the respective shaft section to be inserted into the device particularly easily through the recess, so that its free distal end remains at least partially within the recess. Actuation of the end element then results in force being applied to the correspondingly arranged shaft section during operation.The geometry of the shape is of course not limited to this, but can have any geometry which allows force transmission to the wave sections arranged within it, for example angular, polygonal, triangular or even circular segment-like.

[0054] In a further advantageous embodiment, at least one locking device is provided to connect the two shaft sections to each other and to fix the distal end of the sticker dispenser unit between them. This locking device is detachably connected to the base housing and, in the operating state of the release device, is held in or on the base housing. For particularly stable fixation of the two shaft sections to each other and the fixation of the distal end of the sticker dispenser unit, two locking devices are provided. These can be inserted at least partially into the base housing through openings and coupled to it.

[0055] Coupling can be achieved, for example, by latching, clicking, snapping, pressing, screwing, gluing, or similar methods. In the operating state, the locking devices engage and / or under the continuous, mutually oriented recesses of both shaft sections. The two shaft sections are thus held against each other and clamped.

[0056] Advantageously, the locking means have a gripper-like section which is at least partially complementary to the recesses. Advantageously, when both shaft sections are arranged side by side in the operating state, a circumferential recess is formed, which extends over the entire circumference of the two adjacent shaft sections, or only over a partial circumference.

[0057] In a further advantageous embodiment, the respective locking means is arranged in a holding area provided for this purpose, which is designed as a recess in the base housing.

[0058] In the simplest case, the locking elements are inserted from top to bottom into the respective holding area and guided against the recess formed by the two adjacent shaft sections. The gripper-like section, which has a spring action, is initially subjected to a compressive force. The grippers are then moved apart so that they are guided along the recess and engage under and / or around the two shaft sections.

[0059] If, for example, the empty carrier substrate, which is rolled around the two shaft sections, needs to be removed, both locking devices must be detached from the shaft sections. This releases the frictional clamping of the two shaft sections against each other. A shaft section of your choice can then be removed from the base housing through the designated opening by applying tensile force to the corresponding end element. Advantageously, the locking devices remain in the base housing. This prevents them from being lost.

[0060] The coiled carrier substrate then loses its winding tension and can be easily removed from the base housing and disposed of without requiring any special force. Removing both locking mechanisms prevents the empty carrier substrate from unintentionally unwinding if one locking mechanism is inadvertently removed during use. This advantageously provides a safety feature.

[0061] The release device is advantageously designed as a mobile unit. For example, the base housing could have at least one fastening element, such as a clip or loop, allowing the release device to be attached to a waistband, belt, or arm. This ensures that the user always has the release device readily available, significantly saving time and distance during the work process. Unnecessary trips back and forth to stationary dispensers are avoided. This is also advantageous because it makes the device mobile and allows for hands-free transport when not in use. This is useful, for example, when no sticker needs to be removed and / or goods are being transported. The fastening element is also advantageously removable.This allows the release device to be used both mobile and stationary.

[0062] Depending on the design, the fixing element could, for example, be designed as an arm strap, allowing the release device to be positioned on the user's arm or wrist. If, on the other hand, larger products are to be assembled during the shipping process, it is also conceivable that two or more fixing elements are provided on the base housing, which can be attached to the waistband or belt, for example, by hooking them on. This allows the release device to be carried hands-free.

[0063] It has proven particularly advantageous to manufacture the release mechanism entirely from plastic. This allows for production using injection molding or additive manufacturing, for example. The latter, in particular, offers the possibility of quickly addressing any requirements for the release mechanism, enabling rapid adaptation. Furthermore, manufacturing it from plastic eliminates the need for all metal parts, coil springs, blades, and the like, significantly increasing user safety.

[0064] It is also conceivable that the release device has a cover which serves as dust protection.

[0065] Furthermore, the present invention relates to a method for using a removal device for removing stickers from carrier substrates, as disclosed above, which comprises at least the following steps: a. Guiding a free distal end of the at least one sticker carrier substrate unit into the base housing and then further along predetermined guide paths via the release unit to a first wave section inserted into the base housing, or guiding a free distal end of the at least one sticker carrier substrate unit, which is arranged inside the base housing, along predetermined guide paths via the release unit to a first wave section inserted into the base housing, b. Positioning the free distal end on a surface of the first wave segment, c. Inserting the second wave section into the base housing and pre-fixing the free distal end of the at least one sticker carrier substrate unit between the two facing surfaces of the two wave sections, and d. Clamping the two shaft sections across their recesses by means of at least one locking device.

[0066] Depending on the design, it is conceivable that at least one locking device, or advantageously both locking devices, are already arranged in the recesses provided for this purpose in the base housing. Clamping and securing the two shaft sections together can then, in the simplest case, be achieved by applying pressure to each locking device. This device is then moved from its loose pre-position against the two adjacent shaft sections and secures them by at least partially encircling and / or engaging under both shaft sections.

[0067] This pre-positioning has proven advantageous because it secures the locking elements, which can be described as small parts, against unintentional loss. Particularly advantageous is the ability to apply a compressive force to each locking element during a predetermined vertical displacement and / or a tensile force when removed, without unintentionally sliding out of the base housing and being lost. For this purpose, at least one retainer in the form of a lug can be provided, which prevents and limits the unintentional sliding out of the respective locking element. The resistance exerted by this retainer is sufficient to hold each locking element in its position.However, the resistance can also be overcome with a sufficiently large tensile force, so that the respective locking device can be completely removed from the base housing, for example in case of a defect or a necessary replacement.

[0068] The procedure described here proves to be particularly simple and easy to implement, especially since the resulting operating state can be operated with one hand.

[0069] To reliably detach the stickers from the backing substrate, the end elements, which either hold the respective shaft section in place or are integrally formed with it, are positioned at least partially protruding from the outside of the base housing. The coupling of the two shaft sections also couples the end elements to each other.

[0070] If a closing element is subjected to a force, for example by being rotated by the user, this force is transferred to the adjacent shaft sections, causing them to rotate. This exerts a tensile force on the clamped end of the sticker dispenser unit or on the empty carrier substrate, which extends along the rear guide paths to the sticker dispenser unit itself.

[0071] The sticker backing unit is guided upwards towards the release unit. When a pulling force is applied, the sticker backing unit is guided over the edge of the release unit, where the backing is tilted downwards at a sharp angle back into the base housing and guided towards the two shaft sections. The sticker itself experiences no significant force and remains at the edge, ready for removal. This removal method has proven advantageous, as it allows the user to remove stickers from backings quickly and easily, even when wearing heat-resistant or protective gloves.

[0072] In the simplest case, it is conceivable that the rotation of the end elements can be incremental, for example, by means of corresponding detent positions of the end elements relative to the outer surface of the base housing. At the same time, these detent positions, which could, for example, be designed as a sawtooth profile, prevent unwanted reverse rotation of the two shaft sections. Thus, the detent positions can be understood as a backstop mechanism. Due to the coupling of the two shaft sections, this backstop mechanism can be implemented on only one end element or on both end elements.

[0073] To simplify operation, it is also conceivable that arrow directions could be displayed on the end elements to show the user the correct rotation direction even in stressful situations. This would further facilitate use.

[0074] Furthermore, by actuating the at least one end element, which is coupled to at least one shaft section, the empty carrier substrate is wound around the split shaft.

[0075] Once all the stickers have been used up and only empty carrier substrate remains wrapped around the two wave sections in the base housing, the removal device can be emptied and refilled with simple steps, as described above.

[0076] To empty, at least one, preferably both, locking means is removed from the two shaft sections, for example by pulling them off.

[0077] Subsequently, an arbitrary shaft section is led out of the base housing, for example, pulled out. This breaks the force-fit connection between the two shaft sections and the intermediate support substrate. Furthermore, the circumference of the overall shaft formed by both shaft sections is reduced.

[0078] This allows the second shaft section to be easily removed from the base housing. The empty carrier substrate remains in the base housing in roll form, from which it can be easily removed and disposed of manually.

[0079] In all cases used herein, where this formulation is used within the scope of the present invention, the term "essentially" is understood to mean a deviation in the range of 1% to 30%, in particular 1% to 20%, in particular 1% to 10%, in particular 1% to 5%, in particular 1% to 2%, from the specification that would be given without the use of this formulation.

[0080] Further advantages, features and design possibilities will result from the following description of figures illustrating exemplary embodiments, which are not to be understood as restrictive. Brief description of the drawings

[0082] In the drawings, elements designated with the same reference numerals are essentially equivalent to one another, unless otherwise indicated. Furthermore, components that are not essential for understanding the technical teaching disclosed herein are not shown or described. Additionally, reference numerals are not repeated for all elements already introduced and illustrated, provided that the elements themselves and their function have already been described or are known to a person skilled in the art. Detailed description of exemplary implementations

[0083] In Fig. Figure 1a shows a schematic sectional view of the release device 1. This device has a base housing 2. The base housing 2 serves to hold the other components of the release device 1.

[0084] The basic housing 2 thus forms a sticker dispenser unit receiving area 4 in its lower area, which serves to receive the sticker dispenser unit 6.

[0085] The sticker dispenser unit 6 is inserted into the receiving area 4 and, in the simplest case, is designed as a roll. The roll is placed loosely in the receiving area 4, allowing for particularly easy unwinding of the sticker carrier substrate units 8.

[0086] The sticker carrier substrate units 8 are guided as a strip along the first guide path F1 towards the release unit 10. In this embodiment, the release unit 10 is designed in multiple parts. The release unit 10 has an edge 12 around which the carrier substrate is guided at an acute angle. This acute-angled guidance overcomes the adhesive force between the sticker and the carrier substrate, and the sticker 13 is released as shown in Fig. As shown in 1b, it is separated from the carrier substrate.

[0087] This results in the remaining empty carrier substrate 14 being guided along the second guide path F2 towards the rotating element 16, which is designed as a split shaft, and wound around it. Thus, for the first time, it is possible to provide a clean removal device 1 that simultaneously stores the empty carrier substrate, which can then be easily disposed of afterwards, and the removal device can be reused.

[0088] Furthermore, it has proven advantageous if the release device 1 is to be used as a mobile unit. For this purpose, the base housing 2 has at least one, preferably two or more, brackets 18, which can, for example, be attached to a waistband. In addition to the variant shown here, it is also conceivable to design the brackets 18 as closed units so that they can be slid onto a belt or wristband. This further increases the safety during operation.

[0089] In Fig. 1b is the section view from Fig. Figure 1 shows a perspective view. Here, the guide paths F1 and F2 can be visualized even more clearly. Additionally, a sticker 13, separated from the carrier substrate 14 and ready for removal, is shown at edge 12 of the release unit 10.

[0090] To stabilize detached stickers 13, the removal unit 10 can further have a storage element 15 on which the detached sticker 13 can be held temporarily.

[0091] Fig. 2 shows the exterior view of the in Fig. Figure 1 shows a sectional view of the release device 1. It can be seen that two end elements 20 are arranged laterally on the base housing 2. The end elements 20 serve to hold and position as well as to rotate the split shaft 16 and thus also to wind up the empty carrier substrate 14 and also to release the stickers 13 from the carrier substrate.

[0092] Fig. Figure 3 shows an exploded view of an embodiment of a release device 1. The base housing 2 is shown first. For clarity, a side part 2a is shown separately from the rest of the base housing 2. A through-opening 22 is shown in the side part 2a, through which the first shaft section 24 can be inserted into the interior of the base housing 2.

[0093] The first shaft section 24 has a recess 28a at its first distal end 26. At its opposite end 30, the first shaft section 24 has an at least partially circular projection 32, for example D-shaped, which is complementary to an opening 34 of the end element 20. In the operating state, the projection 32 is arranged in the opening 34 and serves to transmit force to the first shaft section 24 when the end element 20 is actuated.

[0094] Furthermore, the first wave section 24 has another recess 36a near its second end 30. Both recesses 28a and 36a are formed here as circumferential grooves of the lateral surface of the first wave section 24.

[0095] Furthermore, the release device 1 has a second shaft section 38, which is identical in design to the first shaft section 24. The second shaft section 38 also has two recesses 28b, 36b, which are likewise designed as circumferential grooves on the outer surface.

[0096] Both wave sections 24, 38 have in common that the two contact surfaces 40a, 40b do not have such a groove.

[0097] In the simplest case, as shown here, the contact surfaces 40a, 40b are designed as slopes, which advantageously span an angle of 0.5 to 10°. The slopes are shown here without any profile.

[0098] The second shaft section 38 is also inserted into the interior of the base housing 2 through a through-opening (not visible here). Both shaft sections 24, 38 are thus designed to be separable from one another. In the operating state, however, the two shaft sections 24, 38 form a single shaft which is rotatable about a single axis, advantageously the longitudinal axis.

[0099] Furthermore, it shows Fig. 3. The locking means 42a, 42b are inserted from above into the respective holding area 44a, 44b of the base housing 2. This only occurs when both shaft sections 24, 38 are already arranged within the base housing, so that the recesses 28a and 36b as well as 36a and 28b form a circumferential, continuous groove.

[0100] When the locking means 42a, 42b are inserted into the base housing 2 from above, locking means 42a engages the groove 36a, 28b. The gripper section 46 is guided against this groove and initially widened. The gripper section 46 slides in or along the groove and engages around and / or underneath both shaft sections 24, 38. In this way, both adjacent shaft sections 24, 38 can be clamped against each other and against the base housing 2. The two grippers of the gripper section 46 engage around and / or underneath the entire shaft formed by the two shaft sections 24, 38.

[0101] To remove shaft sections 24 and 38 from the base housing 2, both locking devices 42a and 42b are released by applying a force, particularly a tensile force, to the gripper area 46, which releases the gripping and / or under-gripping mechanism. This can be achieved, for example, by means of the release elements 48. This allows for the simple removal of both locking devices 42a and 42b from the two shaft sections 24 and 38. The provision of the two continuous, circumferential grooves ensures that both locking devices 42a and 42b must always be removed. This prevents the two shaft sections 24 and 38 from unintentionally separating from each other.

[0102] The release elements 48 can also be referred to as locking elements, since they serve to prevent the locking means 42a, 42b from being unintentionally removed from the base housing 2 after their initial insertion into the designated recesses, i.e., after assembly. Furthermore, these geometries ensure that the locking means 42a, 42b remain in the released state, as shown in Fig. As shown in 4b, the shaft sections must remain in the upper pre-position and not unintentionally slide downwards. Otherwise, this would prevent the insertion of shaft sections 24 and 38 into the base housing 2.

[0103] Finally, the locking mechanism 50, which is designed as a sawtooth profile 54, is shown. This prevents unwanted reverse rotation. This hook 56, as part of the locking mechanism 50, is guided along the inside of the sawtooth profile 54 during each rotational movement and locks against reverse rotation of the shaft sections 24, 38 by engaging with the acute-angled side of the tooth profiles.

[0104] Fig. Figure 4a shows another external view of the release device 1. Fig. 4b shows a schematic cross-sectional view of the in Fig. The release device shown in Figure 4a is located along EE. The base housing 2 has a holding area 44, which is designed as a recess. A locking element 42a is inserted into the holding area 44 but is not yet engaged. Therefore, the locking element 42a still protrudes partially from the base housing 2.

[0105] The gripper section 46 is located above the shaft sections 24 and 38 in this intermediate state. It is further shown that the gripper section 46 is designed as a spring bearing and that the two grippers can be released from the overall shaft by applying force to both release elements 48. The frictional and / or positive locking connection of the two shaft sections to each other and to the intermediate support substrate (not shown) is then released.

[0106] In Fig. Figure 4c shows another sectional view, in which the locking device 42b is fully inserted into the base housing 2. This also represents the operating state of the release device 1. In this example, the gripper area 46 encompasses and engages under both shaft sections 24 and 38, so that they are positively locked in place.

[0107] Fig. Figure 5 shows another schematic sectional view of the release device 1 without components. This sectional view shows in particular the wedge-shaped design of the two shaft sections 24, 38, which are connected to each other by means of the locking means 42a, 42b by frictional and / or positive locking. For clarity, the empty support substrate is not shown. This would be arranged between the two shaft sections 24, 38 and clamped in place by frictional locking.

[0108] In addition to actively actuating the release elements (not shown), it is also conceivable that simply applying a tensile force to the respective locking means 42a, 42b is sufficient to overcome the holding force of the gripper area 46 and to release the locking effect of the release elements (not shown). This allows for a simple and quick release of the locking means 42a, 42b. A recess 52 can advantageously be provided for this purpose.

[0109] Fig. Figure 6 shows the side exterior view of the in Fig. Sectional view 5 shows that the end element 20 has a hexagonal shape. This ensures that the end element 20 can be rotated securely.

[0110] Fig. Figure 7 shows a schematic view of the locking mechanism 50. This mechanism has a sawtooth profile 54, which prevents unwanted reverse rotation. The hook 56 is part of the locking mechanism 50 and interacts with the sawtooth profile 54. The hook 56 is guided along the inside of the sawtooth profile 54 during each rotational movement and locks against reverse rotation of the shaft sections 24, 38 by engaging with the acute-angled side of the tooth profiles.

[0111] Finally, it shows Fig. Figure 8 shows another perspective view of a detachment device 1, where the same reference symbols as before correspond to the same components.
