Abstract

A portable grout-separating machine is characterized by a scraping tool (7), which is for the representation of horizontal strokes with a motor in connection, wherein the tool for scraping of tile joints (12) is formed and equipped with carbide tipped heads.

Description

1. Scope - wall and floor tile

• 1.1 Preparation for the replacement of a defective Tile or removal of soiled grout.
• 1.2 The problem zone when removing a damaged tile from the dressing is closed with joint mortar joint and their connection to the glaze of the adjacent intact tiles.
• 1.3 Removal of soiled grout in preparation for a Re-grouting while preserving the existing tiles.

2. Marketing

• 2.1 If you want to award the prize of the device opens Both a sales market in the commercial and home improvement sector independently from manufacturer.

3. Design features

• 3.1 In order to avoid accidents deliberately no rotating Tool planned.
• 3.2 Drive the machine over a battery
• 3.3 Drive the machine over a 230 V / 50 Hz mains connection with integrated voltage conversion AC-DC
• 3.4 The power supply can thus be processed tile surface be adjusted.

4. Drive the machine

• 4.1 The machine is powered by an electric motor Drive.
• 4.2 Power is supplied via a 230 V / 50 Hz mains connection with integrated voltage conversion AC-DC. Power plug and converter housing form a unit. The machine is thus operated via a DC low voltage. The power supply in the battery compartment (via a reverse polarity protected adapter on the connection cable 6 ) instead of.
• 4.3 The power supply is via a replaceable battery in the battery bay. Battery and charger form one unit. direct Charging process by connection to a 230 V / 50 Hz safety socket. The battery bay must be protected against reverse polarity.
• 4.4 The tool speed is electronically adjustable ( 3 ).
• 4.5 The drive is for To measure continuous operation.
• 4.6 The machine is commissioned via a button ( 2 ), which must remain operated for safety reasons during operation by hand.
• 4.7 The movement of the machine in the joint is done by hand.

5. Housing and design

• 5.1 The machine housing ( 1 ) is to be manufactured from a suitable material according to ergometric criteria and accepted rules of technology.
• 5.2 An additional screw-on and unscrewable handle, the appropriate receptacle with a collar ( 10 ), which in turn is part of the machine housing and provided with a finely graduated detent, allows the handle of the machine with both the left and the right hand beyond the horizontal and thus can be adapted to local conditions.
• 5.3 The finely graduated locking mechanism is designed to be designed so that an unintentional adjustment is not possible.
• 5.4 About the tool or the tool holder is a transparent, five-sided to arrange closed, hinged protective hood.
• 5.5 The protective hood is in a suitable place with a hose nozzle to the possible Extraction of the mortar dust to provide.
• 5.6 The tool holder and the tool and the joint section to be machined are provided by a suitable light source ( 5 ) to illuminate.
• 5.7 The machine housing is to be equipped with two suitable removable support roller mounts. The spring-mounted rollers ( 9 ) make sure that with increasing penetration of the tool into the joint ( 12 ) by parallel guidance always the entire tool length for each forward and backward movement is used.
• 5.8 The spring force shall be such that when using the necessary manual force in the vertical direction, a uniform elaboration of grout can be done. 5.9. If there is no more vertical force of hand, The machine is lifted out of the joint by the spring force.

6. Tool and tool holder

• 6.1 The tool ( 7 ) is made of a suitable steel coated with sharp-edged grain on the machining side.
• 6.2 All for Machining tools suitable materials can be used (carbide, Ceramic, glass, corundum, diamond .....).
• 6.3 Due to the disorderly orientation of the under point 6.2 designated sharp-edged materials on sawing, grinding or scraping process The machining side of the tool can therefore be spoken of here become.
• 6.4 By appropriate shaping of the tool at the beginning and End is a chisel effect too avoid.
• 6.5 The shape of the tool is so too that they can be adapted to the width of the existing joints by multiple assembly.
• 6.6 The shape of the tool shall be designed so that common Joint widths are covered with a tool.
• 6.7 The length of the tool is to be dimensioned so that even small mosaic or tiles with curves can be edited.
• 6.8 The tool holder ( 8th ) should be designed to cope with the mechanical load during the horizontal working movement.
• 6.9 The tool holder is to be designed so that a tool change or a multiple assembly with a simple tool is possible.
• 6.10 The machine is horizontal with a variable stroke Equip direction to joints of large format tiles, small format To be able to process mosaic or tiles with radii.
• 6.11 The adjustment of the stroke ( 4 ) (Short-stroke / long-stroke) by hand without auxiliary tool outside the machine via a suitable device.

7. Forced operation via guide rail system

Application for large-sized floor slabs

• 7.1 The guide rail ( 11 ) must meet the following criteria:
• a) Lightweight, rustproof material
• b) For cost reasons is a suitable profile form offered by third-party manufacturers to choose
• c) The length is so to choose that joints large-sized Floor slabs (at least one joint longitudinal side) easily processed can be
• 7.2. For locking the guide rail on the tiling are on the two narrow sides of the rail hand-operated vacuum suction ( 13 )
• 7.3. The connection - rail to machine - takes place via suitable detachable connections ( 14 )
• 7.4. The connections are tool-free or with a simple To operate auxiliary tool
• 7.5. The connection - rail to the machine - is constructive to do so that always a parallel leadership and vertical position of the machine is given.

8. Conclusion

stress fractures in tiles often arise only after years, regardless of whether it is an old or new building. Also a fallen down Subject leaves his distinctive tracks. Likewise, a negative change the joints optics by dirt, grease, soap residue u. a. often after years given.

The practiced separation of joints with a cutting disc is conditional due to the enormous fine dust attack as the last possibility of an inhabited object taken into consideration. Also the offered refreshment colors for joints and wall tiles usually do not give the desired result.

Claims (2)

Construction of a portable grout-cutting machine, which is characterized in that this device transforms rotational movements of a motor in strokes and by means of these strokes a scraper tool is moved in the horizontal direction over which tile joints are scraped, being used as a scraper carbide tipped heads, which in different length and width, depending on the joint size, find use. Construction of a joint separating machine, which by it characterized in that the joints do not rotate by means of rotational movements, but are scraped by means of strokes and which electronically is adjustable, so not only straight, but also round joints can be edited and damage the joints are avoided.
