Abstract
Description
- The present invention relates to a device for separating rows of brush hairs, in other words a device which allows to separate a row of so-called tufts of brush hairs from an adjacent row of tufts of hairs, in order to be able to perform certain operations separately on each of these rows.
- More especially still the present invention relates to a device which allows to separate from each other the aforesaid rows of tufts in order, more especially in the course of the fabrication of brushes with rows of brush hairs the lengths of which are different the one from the other, to be able to process these rows of brush hairs in a simple way on one and the same machine, whereby one starts with rows of brush hairs of the same length, certain rows of which are being cut farther than other rows or at once with rows of brush hairs of different lengths.
- It is a known fact that in the brush manufacturing industry, for instance in the course of the manufacturing process of tooth brushes, for various reasons, more and more brushes are in demand the rows of brush hairs of which have different lengths as compared with each other.
- Until now this implies that brushes of this kind, when the rows and fibres introduced have different lengths, must be introduced and processed in separate machines, because it is not possible to process a number of rows of brush hairs of different lengths on one and the same machine.
- The object of the present invention is a device which allows to produce brushes the lengths of the rows of brush hairs of which are different and whereby, from the planting of the tufts of hairs up to and including the complete finishing of the brush, all operations can be carried out on one and the same machine.
- The device according to the invention comprises for this purpose mainly at least one knife with a sharp end, whereby this knife shows on one side a vertical or approximately vertical plane and on the opposite side, starting at the sharp end of the knife, a second side becoming more distant from the aforesaid first side, at least along a part of the length, whereby this knife can be moved backwards and forwards, in such a way that this knife can be very precisely introduced between two rows of brush hairs, through a parallel relative motion between knife and brush, so that at least one row of brush hairs can be curved away to the side with respect to an adjacent row of brush hairs.
- In order more clearly to show the characteristics of the invention, a preferred embodiment of the invention is described hereinafter, as an example without any limitative character, reference being made to the attached drawings, wherein :
- Figure 1 shows a schematic view from above of a device according to the invention;
- Figure 2 shows a view according to arrow F2 in Figure 1;
- Figure 3 shows a section according to line III-III in Figure 2;
- Figure 4 is a view similar to the one of Figure 1, but in a second characteristic position;
- Figure 5 shows a section according to line V-V in Figure 4;
- Figure 6 shows a perspective view of the front part of a knife according to the invention;
- Figure 7 shows a variant of Figure 6;
- Figure 8 shows a second variant of Figure 6;
- Figure 9 shows schematically and in front elevation the various stages of the production on only one machine of a brush with rows of brush hairs of different lengths;
- Figure 10 shows a view from above of Figure 9.
- In the Figures 1 through 5, the device according to the invention mainly consists in two tuft separators or knives, 1 and 2 respectively, which are fixed on a carriage, slide or similar 3, whereby this
slide 3 can move along guides 4-5 respectively, through the cooperation of, for instance, a suitable cam 6 and aroller 7 mounted on theslide 3, whereby between the supports 8-9 of the guides 4-5 andslide 3 drawback means, in this case return springs, 10 and 11 respectively, are provided for. - In front of the knives or tuft separators 1-2, a
support 12 is provided for, on which suitable clamping means 13-14 are mounted, which serve the purpose of suitably clamping abrush body 15 against a thrust-block and with respect to the knives 1-2, whereby, in the present case, the brush body has three rows with short brush hairs, 16-17 and 18 respectively, and two outer rows with long brush hairs, 19 and 20 respectively. - The
knives brush hairs rows brush hairs rows - In Figure 7 there is further shown an embodiment of a knife 21-22 whereby, additionally, at the front end, the knives show each a
slanting face 28 in order so to obtain that the separation for a same penetration of the knives between the hairs be obtained sooner, in other words, along a shorter distance. - It goes without saying that the knives 1-2 may have any other shape and/or section, provided that this shape or section ensures that the aforesaid rows of brush hairs can be pushed the one away from the other. An example of this is given in Figure 8.
- The operation of the device according to the invention is very simple.
- In the position according to Figure 1 the various brush hairs are in their normal state, whereby it is enough to move the
slide 3 in any suitable way so that theknives slanting faces rows brush hairs - The slanting faces 21-22 of the
knives - As a matter of fact, the distance between such rows at the top of the hairs is mostly non-existent, it may even be negative, whilst at the base, this distance however small, allows that the points of the
knives - In Figures 9 and 10, there is schematically shown how the device according to the invention can be used in order to further treat the brush hairs after planting same, whereby it should be noted that planting brush hairs of different lengths is being generally done through conveying hairs of different lengths from two containers.
- In Figures 9 and 10 are schematically shown eight working stations, 31-32-33-34-35-36-37 and 38 respectively, whereby in the
stations stations stations stations - As may be seen from the drawings, it suffices to keep the
knives working stages working stages brush hairs knives brush hairs working stages 33 through 36. - It is clear that one obtains so that in a very simple way, in only one machine, not only can brush hairs of different lengths be planted in one and the same brush body, but also that these brush hairs of different lengths can always be treated further in this same machine, in order to be shaved and to have their fibre ends rounded off.
- In a preferred embodiment, a number of devices can be mounted on an endless chain as described with the aid of Figures 1 through 5, whereby in each of these devices successively, starting at the brush manufacturing machine properly speaking, a brush body with rows of brush hairs of different lengths can be introduced, whereby the aforesaid endless chain is schematically shown in the present case with the
reference 39. Thechain 37 passes along thevarious working stations 31 through 38, which are fixed on only one driving mechanism which is schematically shown with thereference 40. The latter obtains, during the operation of the machine, a backwards and forwards motion with respect to the devices according to the invention which are stopped at that moment. - As a matter of fact, this quite clearly appears from the Figures 9 and 10.
- Although the example described supposes the fact that one starts by introducing rows of brush hairs of different lengths, it is clear that through the application of the device according to the invention one may start in the same way by introducing rows of brush hairs of the same lengths, whereby adjacent rows, for instance in the devices according to the Figures 9 and 10 are treated in a different way in order, amongst others, to obtain different lengths of the brush hairs.
- It is clear that the present invention is not at all limited to the embodiment described as an example and shown in the attached drawings, but that a suchlike device can be carried into effect in various shapes and dimensions without going outside the frame of the invention.
