"Feed arrangement for workpieces and the like in multiple processing machines".

The present invention relates to an arrangement for successively advancing workpieces or the like. in
Multiple processing machines. It relates in particular to arrangements for advancing brush bodies in a brush manufacturing machine, these brush bodies being guided one after the other under the various tools which are shown in FIG
consecutive operations must act on them, in particular the drilling and filling tools.

In such machines a holding device is used, on which the brush body is attached and which is then inserted one after the other in the area of the drilling tools and in the
Filling tools is advanced and finally delivers a finished brush.

It is well known that when drilling and filling the
Brush body can optionally be adjusted or rotated step by step so that the tufts of hair or bristle can be planted in the desired direction in the brush body.

With certain previously known machines, the close-knit The following workpiece holder is pushed forward in a straight line by

009849/0070 BADORiGiNAL

insert new brush bodies at one end of the row of holders and at the same time removed the completed brushes at the other end. In many cases this leads to greater difficulties with himself.

In other known machines, the workpiece holders are advanced according to a circular path, with it however, it is felt to be an important disadvantage that the workpiece holder, by turning them 180 °, reverse their direction; "the compensation of this reversal movement requires double drive means.

A first advantage of the arrangement according to the present invention The invention for successively advancing the brush bodies to be processed can be seen in the fact that only Arrangements or workpiece holders located under the tools receive adjustment movements that correspond to the direction of implantation correspond to the tufts of hair, while the rest of the workpiece carriers are held in place so that while drilling and inserting hair, bristles or fibers into the brush body, inserting new brush bodies in appropriate brush holders or removing completed brushes 25.Bsp. for the purpose of Transfer to a weeding and cutting machine, done fully automatically or by hand without any particular difficulties can be.

Another advantage of the inventive arrangement is to see that the workpiece carriers are always the same Assume angular position, so that the drive arrangement in such Machines can be realized in the simplest possible way

In these workpiece carriers there are also locking elements for Locking the frame 10 and / or the members 18-19 in each case desired working position provided.

In the? In 'Figures 1 to 3 illustrated

009849/0070

form, the master making machine has four such works, Piece holder 7. '

In each workpiece holder 7, the U-shaped frame θ is firmly connected to a rod 25 ^f , which is arranged in a sleeve 25 so that it can be moved longitudinally but cannot be rotated; is. This sleeve is rotatably mounted in the free end of an arm of a cross-shaped drive member 26 which is seated on a drive shaft 27 which is rotatably mounted in the horizontal frame part 28 of the brush manufacturing machine.

The rod 25 'preferably has a square cross-section on.

The aforementioned drive shaft 27 is suitable connected to a drive mechanism, not shown, which allows a step-by-step rotation of the square-shaped drive member 26 each at a certain angle - which in this case always 90 ° is possible. Such a drive can e.g. with . With the help of a Maltese cross, a hydraulic or pneumatic one Arrangement with ratchet wheel and pawl, or in another can be brought about in a known manner.

The aforementioned sleeves 25 go through the cross-shaped Drive member 26 therethrough and each have this on the underside Link a gear 29 which with a Zwiscnenrad 30 in one; handle is, which is rotatably mounted by means of a pin 31 in a correspondingly provided on the arm of the cross-shaped Antrietos member 26 projection 32.

All of the intermediate gears 30 are in the middle Gear 33 in engagement, the e.g. firmly attached by means of bolts 34 to the aforementioned horizontal frame part 28 of the machine.

009849/0070

The effect of the arrangement according to Figures 1 is Ms 3 very simple, as follows. -

The workpiece carriers 7A and 7D, whereupon the Brush body 6 arranged * or of which the completed BtIr- ■ Most must be removed are in a horizontal position Rest position that they automatically assume as soon as the workpiece carrier be removed from the "FullVorriohturigen 4-5.

It is immediately clear that a memory can be arranged above the workpiece _{carrier 7A r,} as indicated in Figure 1, from which unused brush bodies can be placed fully automatically or by hand on the workpiece carrier 7A, while a Device can be provided whereby the completed brushes 35 are automatically removed from the workpiece carrier 7D and delivered to a device for weeding out and cutting off the bristles.

With the aid of the cross member 26, all of the workpiece carriers 7A to 7D are each rotated further through 90 ° so that they each reach the position of the previous carrier. While this rotation work the mentioned gears 29 on the Intermediate gears 30 together with the middle gear 33 in such a way that that the workpiece carriers or the brush bodies are permanently in the same Remain angular position.

* ■

This is achieved by rotating the Cross member 26 according to the arrow F, the gears 30 one rotation obtained according to arrow ¥ l, while the gears 29 according to turn the arrow F £.

Since the gears 29 and 33 have the same effective diameter

■■■ .-. BAD ORtaiNAL

'have, when the cross member is rotated by 90 °, each Gear'29 also rotated 90 ° so that the workpiece holder 7 the same angular position during the entire movement keep.

Furthermore, in a known manner, with the help of the rods 17 and = 24 ·., The pivoting of the frame in the support frame 8 and that of the U-shaped bracket 18-19 in relation to the frame 10 is brought about and determined, while on the other hand suitable means are employed to compensate for the pivoting caused Adjustment of the workpiece holder 7 in relation to the tools acting on it.

These funds can, for example, through appropriate holes in the frame 28 on the shaft 25 ', or directly on the frame 8 the workpiece holder act. V

It goes without saying that during the adjustment of the workpiece carrier 7B and 7C the drive members or rods 17 and 24, as well as the mentioned compensating means in some way temporarily removed from the workpiece holders.

A modified version of the parallel holding arrangement the workpiece carrier is shown in Figures 4 and 5. In these figures the workpiece carriers 7 are flat

25 if arranged on shafts 25 'which are guided in bushes /, which are themselves rotatably arranged in a cross-shaped drive member 26, these sleeves 25 now under the cross member 26 gears 36 carry the diameter of which is exactly half the size like the diameter of the circumference whereupon the axes of the shafts 25 ' lie.

The gears 36 are in this case with a tooth

wheel 37 in engagement with a on the drive shaft 27 of the Cross member 26 freely rotatably arranged sleeve 38 a whole forms which sleeve is freely rotatably mounted in a suitable manner in the horizontal frame part 28 of the machine

At the other end, the sleeve 38 carries a gear 39 which is in engagement with a gear 40, which is connected to a smaller gear 41 fe-st, this smaller gear with one firmly connected to the aforementioned drive shaft27 Gear 42 is engaged. The shaft 27 is supported e.g. on a thrust bearing 43 »which is firmly connected to the frame 1.

The mentioned gears 40 ″ and 4I are freely rotatable a fixed shaft 44 arranged.

As mentioned earlier, the effective diameter is the Gears 36 dem. of the gear 37, and the diameter of the mentioned Gear 39 is the same as the diameter of gear 40, while the effective diameter of gear 42 is twice as large is like the effective diameter of the gear 41.

If, in this embodiment, the cross member 26 is rotated, for example, in the direction of the arrow 1 * 3, the gears 40 and 41 ″ rotate in the opposite direction according to arrow F4 ₁ , namely at an angular speed that is twice as great as that of the Gear 42. The gear 39 and the bushing with the gear 37 thus rotate according to the arrow F5 at a speed that is twice as great as that of the cross member 26, so that the gears 36 with the workpiece carriers 7 rotate according to the arrow Fg and / in such a way that their absolute angular position does not change during the advance of the workpiece carriers 7. _ ■ In the two previous exemplary embodiments,

009849/0070

, the machine sat a total of four workpiece carriers. Of course can have any number of workpiece carriers in a corresponding polygonal arrangement -be provided, wherein the drive member 26 has a corresponding number of arms, and the rotation takes place in each case by a corresponding angle got to.

The gears used in these embodiments can optionally also be replaced by friction wheels or the like will. '* ■

Finally, FIGS. 6 and 7 show a third embodiment of an arrangement for the parallel guidance of the workpiece carriers shown schematically, but their application is limited to machines with four workpiece carriers

In this embodiment, a cross member is on the shaft 27 45 attached, the arms of which end radially at their free ends Have longitudinal slots 46. In these slots "the above-mentioned bushings 25 of the workpiece carriers 7 are arranged, each on the lower End have a square guide block 47, which in a guideway 48 -movable »

This guide track is completely square, so that when the cross member 45 is rotated, the workpiece holder 7 each from one to be moved to the next corner.

The workpiece carriers in the examples described above are suitable for making brushes with tufts of hair or fibers planted at different angles. Of course other workpiece holders can also be attached to the shafts or rods 25 'mentioned, which are used for other work, such as the execution of so-called flat work, suitable

are. In this]? All, the workpiece carrier receives, for example, two straight shifts so that the brush body according to a predetermined Ban first under the drilling tools and then under .the filling devices are pushed.

If a machine is used exclusively for so-called flat work, the mentioned compensation movement is unnecessary, so that the! Parts 25 ^f and-the cans 25 can be made from one piece.

This results in a very simple arrangement which makes it possible to always move the workpieces parallel to itself, and while drilling holes in one or several brush bodies, other brush bodies that have already been drilled with tufts of hair or fibers or the like. be provided while another workpiece holder for removing the completed brushes is ready and an empty workpiece holder to insert. of unprocessed brush bodies is available.

Because the workpiece holders are always parallel to each other the drive can remain as simple as possible.

The filling devices are in the various designs and drilling tools arranged vertically, while the cross * member lies horizontally. However, it would just as well be possible that mentioned tools horizontal or inclined, and the cross member to be arranged vertically or at a corresponding angle of inclination. .

The present invention is by no means limited to that described above as examples. Embodiments, but one can can be realized in many other designs and in any dimensions without exceeding the limits of the scope of the invention.
