The Waxing disc of described type is known.This respect for example can be referring to DE4340367C2.Describe in this patent document and a kind of wax-polishing machine has been described, it has three Waxing discs at the downside that faces the floor that will nurse.Each Waxing disc is installed on the support that can drive rotation, and these supports are placed in around the support axis by a common center drive and rotate.
Summary of the invention
In view of above-mentioned prior art, technical problem to be solved by this invention is, the Waxing disc of described type especially is further improved at the aspect of performance that it is implemented in the processing procedure of floor by its.
This technical problem is solved by a kind of Waxing disc that is used for floor waxing machine, described Waxing disc is contained on the support that has the support rotation that can drive rotation, according to the present invention, if a plurality of single-decks, they can be contained on the support around a disc spins axis respectively rotatably, and radial distance and edge that disc spins axis and support rotation are certain at interval circumferentially are arranged on the support with distributing.Correspondingly by a plurality of single-decks that own rotation is arranged, being combined into one in case of necessity can be with the Waxing disc of the simplest mode by user's replacement.Based on this design, supporting disk preferably only is used to install the rotating shaft with fixed disk.These rotating shafts of spiraling are arranged on the public circumference of supporting disk.Based on according to this design of the present invention, compare with the Waxing disc in the known systems, obtain a kind of polishing or waxing effect of improvement.Carved up original according to the present invention by arranging a plurality of single-decks, meanwhile, still caused the work sheet that originally only is suitable for a Waxing disc thus by the rotation of the support that continues to provide around its rotation only by a Waxing disc predetermined process face.The rotation stack that each single-deck is possible rotatablely moves and undertaken by the wax-polishing machine drive unit by entire bracket is for example held under the constant situation acting on trying hard to keep on the floor that will nurse by wax-polishing machine thus, has improved the polishing effect of whole Waxing disc.
In the favourable expansion design of of theme of the present invention, the axis of dish for example approximates 1.1 times to 1.6 times amount of radius size radially from the axis of the support distance at least about a single-deck radius size.The layout of single-deck preferably is chosen as in addition, makes them or the shop layer that is installed on them does not contact or do not contact substantially, thereby single-deck is not supported one another when himself rotates or even interferes with each other.Preferably, the axis of dish equidistantly is laid on the circumference each other, and this helps coiling the uniformity of operation more.Based on this design, be benchmark with the support rotation, angle folded between two adjacent single-deck rotations equates that all the time for example this angle is 90 ° when arranging four single-decks.In addition, under the situation of three or more single-decks, they are arranged as, when first single-deck along the linear of a terminal pad rotation during to second single-deck, the 3rd single-deck must be dodged.According to this theoretic hypothesis of transfer, the 3rd single-deck is along circumferentially pressing from both sides in the wedge shape that is embedded into other two single-decks formations.It is approaching as much as possible each other to reach single-deck thus, so that by arranging that more a plurality of single-decks constitute an approximate closed nursing face.In addition, by the rotation that supporting disk provides, based on being cross-linked of each working face, the tracks that reaches single-deck to small part is overlapping.
Article two, the mutual air line distance of disc spins axis is equal to or less than three times that coil radius, for example also preferably corresponding to dish two to three times of radius, tend to be slightly larger than the twice of dish radius, so that taking into account under the discontiguous each other situation of single-deck thus, constitute an approximate closed or approximate face that links to each other by single-deck.Therefore, described air line distance preferably approximates 2.1 to 2.5 times that coil radius.
Single-deck can be for example with among rotatablely moving of supporting disk is placed in rotation relatedly; Also can establish independently drive unit in addition.But preferred relatively therewith, single-deck be not provided with the active drive device aspect the rotatability of its drum axis.Rotatablely moving of each single-deck based on the retain strength that produces brokenly that obtains because of friction on the floor that will nurse, realized by the relative motion with respect to supporting disk.Based on this design, prevent known sticking-sliding (Stick-Slip) effect that causes by Waxing disc.This effect for example occurs in when wherein existing the floor of not drying floor wax fully to handle.Produce so-called jumping in this case, consequently may cause damaging drive system.Each other with respect to supporting disk rotatability independently, avoided above-mentioned negative effect by single-deck.Obtain a kind of glitch-free course of work, can be owing to the Stick-Slip effect is damaged drive system.Further improve polishing or waxing effect thus.By " random " rotation of single-deck, realize being equipped with the tranquil especially operation of wax-polishing machine of these single-decks.In addition, can realize removing the dirt of bonding and the wet wax liquid etc. that distributes based on the scheme of being advised.Also can use the viscosity cleaning agent.Insensitive when in addition, having proved the scheme work of being advised already for passing through unknown pretreated floor.
It is protruding that single-deck can be set to radially to surpass support in upright projection, thereby increased the working face of whole Waxing disc with respect to the bottom surface of supporting disk.Different with it, single-deck also can be set to, and makes them tangent with the circumference of its circumference and supporting disk in projection.Can also differently single-deck be chosen as along circumference, make them in projection, be contained in the inside of supporting disk fully.
By preferred expansion design, single-deck removably, especially be contained in above the support by constituting kayser connection etc.Single-deck can be mounted to relatively therewith, allows them around the swing of single-deck rotation, and to compensate possible floor unevenness, therefore described swing with respect to floor level is limited to low throw.With it differently, single-deck also can for example be packed in the support by this way, that is, only the nursing of single-deck shop layer exceeds the supporting card ground that faces the floor that will nurse and stretches out.
Supporting disk also can be fixed on to be replaced in the box.By the known a kind of replacement box of laying Waxing disc of DE19728972A1.Therefore absorbed the content of this patent application in the disclosed content of the application, also for this purpose, the feature of this patent application is received in the application's protection domain comprehensively.In addition, can for example on the two sides of support single-deck be set, they face rack surface respectively and have identical shop layer, but have different shop layers for opposed stent cover.Can spread layer replacing in the easiest mode by replacing box.Do not need to change single disc.Exactly, when needed whole box is pulled down and replaced with another from machine.
Each single-deck is set to partly surpass replacement box border land and stretches out in upright projection.Difference arrives with it, also it is contemplated that a kind of layout, is contained in fully in upright projection by this layout single-deck and replaces box inside.By another kind of preferred expansion design, in replacing box, hold three supports that respectively comprise three single-decks, therefore obtain a replacement box of nine single-deck configurations altogether.Here, the triangular layout of three support employing support rotation lines.The layout of this almost contact also is preferred for the single-deck on each support, thus by the support rotation be in support on the single-deck that can rotate freely obtain a kind of work sheet that links to each other.
