"Device for the step-by-step conveyance of production parts, tools and the like, especially in the case of brush manufacturing machines" .

The present invention relates to the step-by-step promotion of production parts, tools and the like., in particular on the step-by-step movement of so-called production part holders in brush manufacturing machines.

As is known, in brush manufacturing machines, the manufacturing part holders are normally tri-directional moved, namely in a tilting movement depending on the width of the brush body - the so-called width movement; in a Tilting movement depending on the length of the brush body - the so-called Length movement; and in a vertical or horizontal movement of the brush body, the so-called depth movement; whereby these three movements are communicated to the production part at the same time according to a prescribed scheme must be.

There have been several such. Devices proposed; however, they all have the disadvantage that they are relatively complicated and expensive, while operational safety often remains inadequate.

The present invention relates to such a device for the step-by-step conveyance of production parts

and the like, which is exhausted, their operational safety is extremely large and is relatively cheap.

This device consists at least of the connection of a displaceable element that is directly or is indirectly connected to the manufacturing part or the like; from a lever connected to the aforementioned element, which in turn is connected to a second and third lever; from means that these latter two levers simultaneously influence in order to communicate a pivoting movement to them in connection with each of the two last-mentioned levers a stop and a means that can cooperate with these attacks in accordance with a specific program in order to achieve a specific To achieve conveyance movement of the first-mentioned element.

In order to better demonstrate the features of the present invention, the following are given by way of example and without any restrictive intent - some preferred embodiments with reference to the accompanying illustrations, in which:

Figure 18 shows a possible expansion of the device according to the present in a schematic manner Invention reproduces.

In Figure 1 is a device A according to the present Invention reproduced, which allows an element 1 to be brought into certain positions, with reference to a reference line or plane A-A.

For this purpose, the aforementioned element 1 is connected to a rod 2 which runs through a guide 3 and in the Point 4 is articulated to a lever 5. The latter lever 5 is articulated in points 6 and 7 with rods 8 or 9 connected, which also run through 10 and 11, respectively.

The other ends of the rods 8 and 9 are articulated at points 12 and 13 with levers m and 15, respectively, the latter levers 14 and 15, respectively, are articulated to rods 18 and 19 at each end in points 17 and 17, respectively in turn connected to a common bar 20

are shifted parallel to themselves in guides 21 and 22, respectively can be.

The rod 20 is in connection with a si ° driving Cam 23 which is driven by a shaft 24.

Each of the levers 14 and 15 is in its center, i.e. in the points 25 and 26 articulated to a rod 27 and 28 respectively, which runs through a guide 29 and 30, respectively the free end of which has a stop 31 and 32, respectively.

In the vicinity of each of these stops 31 and 32 there are further adjustable stops 33 and 3M-.

Of course, the device in question is to be equipped with springs, stops and the like, so on the one hand the device always pulled into a certain position is or remains in it, and on the other hand, when this position is reached, the device is prevented from moving further deformed.

In order to achieve a predetermined displacement of the element 1 in certain positions of the device, the ratio a / b in lever 5 must be precisely defined, as will be shown below.

The operation of such a device is very simple and can be described as follows.

When the device is in the position shown in Figure 1, that is, when the stops 33 and 34 are outside the courses of the stops 31 and 32 of the rods 27 and 28, the cam 23 is the rod 20 parallel to move back and forth by themselves, with the result that the rods 18 and 19 also move back and forth

received so that the levers 14 and 15 get a swivel movement, around the hinge points 12 and 13, respectively. The points 12 and 13 always stay in the same place, in which? the aforementioned Springs or the like ensure that all parts of the device are always pressed or brought in the direction of the cam 2 3 or be held.

When the height of the cam 23 is reached, the device is in the position shown in FIG it is noticeable that the rods 8 and 9 have not been moved, so that the rod 2 and the element 1 have not been moved either have been shifted relative to the reference line A-A. As it continues to rotate, the cam 2 is 3 over the next rod 20 under Influence of the aforementioned springs the device back into the Bring the position as shown in Figure 1, etc. It is therefore clear that when the device is in the position shown in FIG Figures 1 and 2 is reproduced, the rotational movement of the cam 23 only has the consequence that the levers IU and 15 a Carry out a swivel movement without the element 1 shifting in any way.

In order to move the element 1 in a certain way, the moment the device is in position is, as shown in Figure 2, one or both of the stops 33 and 34 under one of the corresponding Stops 31 and 32 are brought so that when the rod 2 moves back to the position as shown in Figure 1 is shown, the rods 27 and 28 are held »so that the corresponding lever 14 and 15 a pivoting movement around its pivot point 25 or 26, which has the consequence

that the rod in question 8 or 9 and the rod 2 with the Element 1 can be moved over a certain distance.

For clarification, the status of the device is shown in Figure 3 reproduced as it results from striking the stop 33 under the stop 31 of the rod 27.

This has the consequence that the lever IU pivots during the return of the rod 2, but this time with the point as a fulcrum, so that the rod 8 is pushed upwards. The latter forces the lever 5 to pivot around the fulcrum 7, so that the rod 2 and thus the element 1 is displaced from A-A to the surface B-B, the distance between this displacement is equal to C.

This value is of course a function of the distances a and b of the lever 5.

When the stop 34 is placed under the stop 32, As shown in Figure 4, the same thing happens, so to speak, but the lever 5 then pivots about point 6, so that another displacement of the element 1 is obtained. In fact, in this case, element 1 is shifted from A-A into an area C-C, the distance of this displacement z. B. equals d. In Figure 5 is indicated schematically in which way the device works when both stops 33 and 3 «+ below the stops 31 and 32 of the rods 27 and 28 can be set. In this case, the two levers 14 and 15 pivot in the same way about the pivot points 25 and 26, so that the lever 5 is displaced parallel to its axis, with the result that the rod 2 and the element 1 are displaced learned from the aforementioned reference line A-A after the

• III!

Reference line or reference surface DD brings, the distance of this shift being equal to e and this again a function of the ratio of the * distances a. and b on lever § i? t _;

In this way one obtains a device with which it is possible from a drive with certain always constant Rash to get different rashes of the element 1, the distance between these rashes on the ratio of the Values a and b on lever 5 is conditional. In this case, element 1 can be divided into four different terms, and from 0 to the maximum deflection of the cam 23.

If one assumes, for example, that a = 50 mm and b = * 100 nan, and that the maximum deflection of the cam 23 is equal to h5 mm, then when the stop 3h is switched on, the element 1 is shifted by 15 mm, while when the At deflection 33, element 1 is shifted by 30 mm and when the two stops 33 and 34 are switched on, element 1 is shifted by 45 mm.

If it appears necessary or desirable for such a device to have a wider range of deflection distances offers, further levers can be added, whereby by selecting suitable ratios between the load arm and force arm of the levers certain series of deflections of the element 1 can be obtained. An example of this is given in Figure 6 shows a device B which allows 16 different displacements of the element 1 to achieve.

In this case, such a device B consists of two devices A-A 'as in Figure 1, the two

¹ <I · I ι ι

* I 4 t ι

Rod pairs 18-19 are all connected to a rod 35, with the the squat 23 also works together.

The rods 2 of the devices A and A ¹ are articulated at points 36 and 37 to a lever 38 which is articulated to a rod 40 at a point 39. The latter is guided by a guide 41 and is connected to the aforementioned element 1.

In order to achieve a predetermined displacement of the element 1 in certain positions of the device, must the ratios a: b and c: d of levers 5 and 38 are precisely defined; where the values a and b of the two levers 5 are mutually exclusive can be the same or different from one another.

The mode of operation of such a device is so to speak the same as described above with reference to Figures 1 to 5, but with the difference that the Displacements of the rods 2 are communicated to the lever 38, depending on the stop or depending on the stops that are switched on the displacement of element 1 is determined.

Here, too, the Dement I is not informed of any postponement, if neither of the stops 33 or 34 is switched on while this element 1 is undergoing a displacement, that is maximum The deflection of the cam 23 is the same when both stops and both stops 34 are switched on. These states are shown in Figures 7 and 11 respectively.

For the sake of clarity, FIG. 8 shows the position that the device B assumes when only the stop 33 of the device A is switched on; in Figure 9 is the position b9 Ö Ο ^ δίΜ ^^^? ^{11 connections 33 and} ^ ^the

Device A is shown, and in Figure 10 is the state when the stops 33 and 34 of the device A and stop 33 of the device A 'are switched on.

It goes without saying that when the stop 33 of the device A is switched on, a different position is established appears as if the stop 33 of the device A 'were switched on, etc., in which case fifteen possible positions are shown can be, depending on whether you have one, two, three or four of the stops 33-34 with the corresponding stops 31-32 can work together.

An embodiment is shown schematically in Figures 12 to 17 reproduced as it was described with reference to Figures 6 to 11 »and with the device all the details shows, which have been described in the foregoing. In this case the element 1 consists of a fork with each prong one has inwardly directed rack 42 and 43, respectively. The joints 6, 7, 25, 26, 36 and 37 mainly consist of running wheels that stand on a shaft which in turn with the relevant one Lever is attached and these wheels are mounted in U-shaped parts 44, 45, 47, 'r7, 48 and 49, the are attached to rods 8 or 9 or 27 or 28 or 2 in order to achieve such that when pivoting the relevant Lever a transverse movement of these levers is possible, namely transversely to the rod with which they are articulated.

In this case, for example, between each of the guides 3 and the lower end of the rods 2 springs 50 and 51 are provided, by means of which the device is always held or brought back to the neutral zero point. In this version

are the rods 18 and .ι 9 by ^ h joints 52 and 53 with levers 54 or 55 connected, which are connected to the rod 35, the tert consists of a shaft »which is supported in points 5, 6 and 57 is.

On the shaft 35 an additional lever 58 is also attached which by means of a running wheel 5 9 continuous with the aforementioned Cam 23 cooperates constantly. Finally, the stops 33 and 31 are mounted freely pivotable on a shaft 60, each stop can be moved individually, by means of the device indicated by 61, which consists of a hydraulic or compressed air cylinder, a magnetic switch or the like.

The way in which · the element 1 in the embodiment according to Figures 12 to 17 is shifted, corresponds to the way that was described above with reference to Figures 6 to 11 has been described. Each of the racks U2 and 43 acts in this Fall with a tooth segment 62 or 63 together, both segments being freely rotatable on a shaft 64 and each tooth segment 62 or 63 has a rear extension on which by means of a pin 65 before crescent-shaped pawl 66 or 67 is attached and cooperates with a locking disk 68 and 69, respectively. The two prongs of a fork 70, which by means of a pin 71 is pivotably attached to the machine frame and by a pressure piston 72, a magnetic switch or the like is controlled.

It is thus achieved that when the control drive 72 is put into operation, the fork 70 is either the pawl 66 or the pawl 67 depresses while under the influence

kung a spring 73 or 7m, which between the rear extension of the tooth segment 62 or 63 and the corresponding pawl is attached, the corresponding pawl 66 or 67 engages in the locking disc 68 or 69, while the opposite pawl is simultaneously released from the corresponding locking disc is drawn. In the course of the displacement of the element 1 or the racks 42 and 43, it is achieved that depending on the Shifting this element 1 experience one of the pawls 66 or a certain angular pivoting and so either the Drive lock washer 68 or lock washer 69 so that shaft 64 is rotated through a specified angle at a specified angle The direction of rotation rotates, which has the consequence that an element 76 is displaced by means of a worm 75, which is indirectly or is directly connected, for example, to a production part holder of a brush production machine.

A device as shown in Figure 12 is used for longitudinal movement, width movement and depth movement in a brush manufacturing machine, in the case that also a sliding movement is required, a fourth such device can be attached.

As an example of such a device in which a regularly increasing or decreasing series of displacements of the element 1 is reached, the distances a and b on the lever 5 can be selected to 50 mm and 100 mm, and the distances c and d on lever 38 to 50 mm and 200 mm. In this case ranks that if none of the attacks. 33 or 34 is switched on, the element 1 does not experience any displacement while when switching on the following stops, element 1 has a

It is understood that when one or both of the levers ¹ are rotated by 180 ° compared to the 5 position of the lever 38, when switching certain stops 33 and 34, other displacements conclusion as in the previous example; however, you always get an arithmetic series that jumps by 3 mm.

It is also a matter of course that if the relative distances a, b, c and d are changed, other orders of magnitude of the steps will result, with the possibility of creating regular or irregular steps. The definition of these ratios depends in each case / on the production part that has to be moved.

One will preferably strive to choose the aforementioned ratios in such a way that a regularly progressing one or regressive series displacements of the element 1 is achieved.

Of course, the number of times an element has been moved * 1 according to the present invention can be aged in various other ways.

This can be achieved, for example, by connecting the rods UO of the two B devices to each other as shown in Figure 6 connected by an eighth lever who> ". n, and then guesses to connect a rod, which in turn is connected to the element 1 is; by uncoupling one or more of the rods 8 or 9 / from a grand device A, i.e. using a lever to connect, which carries a rod 8 or 9 at each of its ends which each by means of a lever m or 15 ii with a rod 20 or 35 is connected, each of these levers can be provided with a stop so that a rod 8 or 9 correspond to two stops, etc.

An example of the latter possibility is shown in its simplest form for a device B in Figure 18, where, for example, the rod 8 of the device I ^{1 is} shortened and articulated to a lever 17, with which two rods 7 8 and 79 are connected and in turn are articulated to the levers 80 and 81, which are articulated at their other end to the aforementioned rod 35 by the rods 82 and 83, respectively.

Each lever is also articulated with a rod 84 or 85 connected, each of which has a stop 86 or 87 with which sliding stops 88 and 89 can work together.

It clearly emerges from this that in this way, in comparison with the embodiment according to Figure 6, a further eight Stages are obtained.

It also emerges clearly from this that by this doubling of the rod 9 of the device A ^f or the rod 8 or S of the device A, eight further steps are also obtained, which, however, are always due to the presence of the levers 5 and 38 on the displacement of the Element 1 will cause a different effect.

Eg there is also the option to set the number of To • To increase the available steps between two limits, namely 0 and the maximum deflection of the cam 2 3, two or to double more bars in the manner described above.

Such a doubling of a rod 8 or 9 can of course also be used in the case of the basic device A. will.

The present invention is in no way restricted to those described above and given as examples Embodiments, but can come in all sorts of forms and Dimensions are shown without exceeding the scope of the invention.
