Description

TECHNICAL FIELD

[0001] The invention relates to a hand-held instrument for outputting a filling material into a joint. The hand-held instrument is embodied, for example, as a cartridge extruder and / or a hose bag extruder. The filling material is, for example, a joint sealing material, in particular a silicone or an acrylic resin. The hand-held instrument comprises a gripping assembly for manually gripping the hand-held instrument and moving the hand-held instrument along a joint run. The hand-held instrument furthermore comprises an output mechanism for outputting the filling material into the joint. SUMMARY

[0002] The task of the invention is to provide a hand-held instrument which makes it easy for a user to achieve a desired body geometry of a filling material body formed by the outputted filling material when outputting the filling material into a joint, for example a body geometry which is as uniform as possible. The filling material body has, for example, an elongate, in particular string-shaped, body geometry and should suitably have a constant width along the length of the filling material body.

[0003] The task is solved by a hand-held instrument according to the main claim of the invention. The hand-held instrument comprises a sensor mechanism which is configured to detect an influencing variable which influences the body geometry of a filling material body formed by the filling material outputted into the joint. The influencing variable is, for example, a hand-held instrument speed with which the hand-held instrument is moved, or a joint geometry which relates to the joint. The hand-held instrument speed can also be referred to as a pulling speed. The hand-held instrument is configured to match an output rate at which the output mechanism outputs the filling material on the basis of the detected influencing variable. The output rate is the amount of filling material outputted per time unit.

[0004] In this way, the hand-held instrument can compensate for one or more influencing variables which act as disturbances, such as, for example, a varying hand-held instrument speed and / or a varying joint geometry, and thereby prevent the one or more influencing variables from influencing the body geometry of the filling material body in an undesirable manner.

[0005] If, for example, a user guides the hand-held instrument along a joint run with a varying, that is to say non-constant, hand-held instrument speed when outputting the filling material, this leads in a conventional hand-held instrument to more filling material being outputted per length unit of the joint run at joint sections at which the hand-held instrument speed is smaller than at joint sections at which the hand-held instrument speed is higher. A filling material body having a non-uniform body geometry results.

[0006] According to a preferred design, the hand-held instrument speed can be detected by means of the described hand-held instrument and the output rate of the filling material is matched to the detected hand-held instrument speed. The hand-held instrument outputs the filling material at a higher output rate, for example, in the case of a detected higher hand-held instrument speed than in the case of a detected lower hand-held instrument speed. In this way, the influence of a varying hand-held instrument speed on the body geometry can be compensated and, for example, a uniform body geometry can be achieved despite a varying hand-held instrument speed.

[0007] If, for example, the seam geometry, in particular the seam width, varies along the seam course, in conventional hand-held instruments it can result that at seam sections at which the seam width is smaller (and thus less filling material is required for the filling and / or covering of the seam) more filling material is output than is required for the current seam width, and at seam sections at which the seam width is larger (and thus more filling material is required for the filling and / or covering of the seam) less filling material is output than is required for the current seam width. Along the seam course, an inhomogeneous filling and / or covering of the seam results.

[0008] According to a preferred design, the seam geometry, in particular the seam width, can be detected by means of the described hand-held instrument and the output rate of the filling material is matched to the detected seam width. The hand-held instrument outputs the filling material at a higher output rate, for example, in the case of a detected larger seam width than in the case of a detected smaller seam width. In this way, the influence of a varying seam width on the filling and / or covering of the seam, in particular of the body geometry, can be compensated and, for example, a uniform filling and / or covering of the seam can be achieved despite a varying seam width.

[0009] Advantageous refinements are the subject matter of other embodiments of the application.

[0010] The application furthermore relates to a method for outputting a filling material into a seam by means of a hand-held instrument, in particular a cartridge extruder and / or a hose bag extruder, comprising the following steps: moving the hand-held instrument along a seam course, outputting the filling material into the seam, detecting an influencing variable which influences the body geometry of a body of filling material formed by the filling material output into the seam, and matching an output rate on the basis of the detected influencing variable, at which the filling material is output.

[0011] Suitably, the method is carried out by means of the described hand-held instrument and / or is designed in accordance with refinements of the described hand-held instrument.

[0012] The application furthermore relates to an additional instrument for releasable mounting to a drive instrument for forming a hand-held instrument for outputting a filling material into a joint, comprising an output mechanism for outputting a filling material into a joint, which can be driven by means of the drive instrument, and a sensor mechanism, which is configured for detecting an influencing variable influencing the body geometry of a filling material body formed by the filling material output into the joint, wherein the additional instrument is configured for providing a control signal to the drive instrument on the basis of the detected influencing variable in order to control the driving of the output mechanism and thereby to match an output rate at which the output mechanism outputs the filling material.

[0021] In the subsequent explanations, reference is made to spatial directions "x-direction", "y-direction" and "z-direction" which are oriented orthogonal to one another. The x-direction and the y-direction are horizontal directions and the z-direction is a vertical direction (in a horizontal use position of the hand-held instrument 10).

[0022] Figure 1The handheld instrument 10 is shown along with a processing area 83. The processing area 83 has a seam 71. Exemplarily, the processing area 83 includes a first area segment 84 and a second area segment 85, and the seam 71 is located between the two area segments 84 and 85. Area segments 84 and 85 are, for example, building materials, such as slate. For example, the first area segment 84 is slate, a slab, a door frame, a window frame, or a strip. The second area segment 85 is, for example, another slate or wall. The seam 71 between area segments 84 and 85 can also be referred to as a gap or void.

[0023] Exemplarily, the handheld instrument 10 is implemented as a barrel extruder and / or a tubular bag extruder. The handheld instrument 10 can also be referred to as a filler container extruder. The handheld instrument 10 is used to output filler material 72 into the seam 71. The filler material 72 is, for example, silicone or acrylic resin. Suitably, the filler material 72 is temporarily provided in the filler container 2, such as a barrel or tubular bag, and output from the filler container 2 into the seam 71 by means of the handheld instrument 10.

[0024] The handheld instrument 10 includes a gripping assembly 73 for manually gripping the handheld instrument 10 and guiding the handheld instrument 10 along the seam 74. Figure 2 (As shown in the diagram) The handheld instrument 10 can be manually carried by the user and moved and positioned freely in space. The handheld instrument 10 has no fixed or suspended location. The seam orientation 74 is the orientation of the seam 71 along its longitudinal direction. Exemplarily, the seam orientation 74 is along the y-direction (that is, perpendicular to...). Figure 1 The attached plan shows the orientation.

[0025] The handheld instrument 10 further includes an output mechanism 75 for dispensing filler material 72 into the joint 71. Exemplarily, the output mechanism 75 includes a compression mechanism 3 for compressing the filler material container 2 to cause the filler material 72 contained in the filler material container 2 to be dispensed. The filler material 72 is dispensed into the joint 71 via an output element 34, such as an application end.

[0026] The handheld instrument 10 further includes a sensor mechanism 76 configured to detect influence parameters affecting the volume geometry of the filler material body 78. The filler material body 78 is formed by filler material 72 being output into the joint 71. The filler material body 78 can also be referred to as a weld. Preferably, the influence parameters are the handheld instrument speed v and / or involve the joint geometry.

[0027] The handheld instrument 10 is configured to match an output rate r based on the detected influence parameter, at which the output mechanism 75 outputs filler material 72. The output rate r is the amount of filler material 72 output from the handheld instrument 10 per unit of time.

[0028] For example, the handheld instrument 10 has a squeezing element 12 for squeezing the filling material container 2 to cause the filling material 72 to be output from the filling material container 2. The handheld instrument 10 is specifically configured to match the output rate r by matching the speed of the squeezing element 12. For example, the handheld instrument 10 has an electric drive 16 for driving the squeezing element 12 (see...). Figure 3 Or 4) and configured to match the rotational speed of the electric drive 16 based on the influence parameter (e.g., by matching the current flowing through the electric drive 16) so as to match the output rate r.

[0029] Suitablely, the handheld instrument 10 is configured to continuously detect influencing parameters and continuously match the output rate r based on the influencing parameters. For example, the handheld instrument 10 continuously detects the current handheld instrument speed and / or the current seam geometry and continuously matches the current output rate r with the current handheld instrument speed and / or the current seam geometry.

[0030] Preferably, the handheld instrument 10 is configured to match the output rate r based on the detected influence parameter, such that the filler material body 78 formed by the filler material 72 output to the joint 71 has a preset volume geometry, particularly a preset width b, preferably a constant width b. For example, preset information is stored in the handheld instrument 10, which presets the volume geometry, particularly the width, of the filler material body 78. The handheld instrument 10 is configured to match the output rate r based on the detected influence parameter and the preset information, such that the volume geometry of the filler material body 78 corresponds to the preset information.

[0031] Suitablely, the handheld instrument 10 is configured to match the output rate r based on the influencing parameter, such that the output mechanism 75 outputs a preset, particularly constant, amount of filler material per unit length along the seam direction 74.

[0034] The handheld instrument 10 is in particular configured for matching the output rate r based on the detected handheld instrument speed v such that the filling material body 78 has a pre-set body geometry, in particular a pre-set width b, preferably a constant width b, in particular along the joint course 74.

[0035] Figure 2 A respective matching scheme for the output rate r is shown. In Figure 5 The user performs a handheld instrument movement 86 with the handheld instrument 10, wherein the handheld instrument 10 is in particular guided with the output element 34 along the joint course 74. Figure 5 A time course of the handheld instrument speed v, the output rate r and the width b of the filling material body 78 is shown. The width b is the width of the filling material body 78 orthogonal to the longitudinal direction of the joint course 74. The width b is in particular the width of the part of the filling material body 78 that is above the joint 71 or covers the joint 71.

[0036] Suitably, the handheld instrument 10 is in addition configured for decreasing the output rate r of the filling material 72 in response to a detected decrease of the handheld instrument speed v. Suitably, the handheld instrument 10 is configured for providing the output rate r in proportion to the detected handheld instrument speed v and / or in a monotonic, in particular strictly monotonic, relationship with the handheld instrument speed v.

[0037] That is, the handheld instrument 10 outputs the filling material at a higher output rate r in case of a first detected handheld instrument speed v than in case of a second detected handheld instrument speed v that is lower than the first detected handheld instrument speed v.

[0040] Preferably, the handheld instrument 10 is configured for matching the output rate r based on the detected joint geometry such that the body of filling material 78 has a preset body geometry, in particular a preset width b, preferably a constant width b. The width b is the width of the body of filling material 78 in the longitudinal direction orthogonal to the joint course 74. The width b is in particular the width of the part of the body of filling material 78 that is above or covers the joint 71.

[0041] Preferably, the handheld instrument 10 is configured for increasing the output rate r of the filling material 72 in response to a detected rising joint width. Suitably, the handheld instrument 10 is furthermore configured for decreasing the output rate r of the filling material 72 in response to a detected falling joint width. Suitably, the handheld instrument 10 is configured for providing the output rate r in proportion to the detected joint width and / or in a monotonic, in particular strictly monotonic, relationship to the joint width.

[0042] That is, the handheld instrument 10 outputs the filling material at a higher output rate r in the case of a first detected joint width than in the case of a second detected joint width that is lower than the first detected joint width.

[0043] According to a particularly preferred design, the handheld instrument 10 is configured for taking into account, as influencing variable, not only the handheld instrument speed v but also the joint geometry, in particular the joint width. That is, the handheld instrument 10 matches the output rate r based on the handheld instrument speed v and based on the joint geometry, in particular on the joint width, simultaneously. The relationship between the output rate r and the handheld instrument speed v and the relationship between the output rate r and the joint geometry are preferably as described before.

[0067] In the following, the preset information shall be discussed in more detail. The preset information presets, for example, a desired body geometry, in particular a desired width, which shall be achieved by the matching output rate r of the filling material body. Furthermore, the preset information can preset a desired filling material quantity per length unit which shall be achieved by the matching output rate r.

[0071] The user adjusts the desired standard joint size manually before starting work, for example by means of a preset information, and cuts the application tip accordingly. If possible, the application tip can be cut to size with the aid of an auxiliary tool. In addition, a cut-out opening for optimum material spreading can be output as a recommendation prompt by means of the display unit 81. The user positions the application tip at the gap geometry, that is to say, the joint 71, starts the hand-held instrument 10, in particular the electric drive 16, and pulls the hand-held instrument 10 along the joint run 74 at an arbitrary pulling speed, that is to say, hand-held instrument speed v. Here, the hand-held instrument 10 applies the correct amount of filler material at all times by matching the output rate r.
