Abstract

An apparatus for making bristle tufts has a box-type magazine (1) for bristles (2), which have been cut to length, and at least one tubular tuft gripper (6) which can be inserted in the magazine (1) and thereby separates a bristle tuft from the bristle supply and which widens on the inside from the opening (22) over a short axial length (s) in a constant curve and, adjoining said curve, has an axially parallel wall (23) on the greatest part of its axial length with formation of a larger inside cross-section compared to the opening. The magazine (1) has an oscillating bottom (5), which "fluidises" the bristles, and an oscillating wall section (4) which jolts the bristles into a flush position. <IMAGE>

Description

The invention relates to a device for generating Bristle bundles for the production of bristle goods with a shaft-like magazine that has a larger stock of cut to length and roughly in parallel picks up layered bristles, and with at least one tubular bundle gripper at the mouth opening the desired cross section of the bristle bundle has corresponding internal cross-section which in the Magazine is retractable and at least one bundle of bristles separated from the bristle stock (e.g. DE-A-2 335 468).

In the present context, bristle goods are not just brushes, brooms, brushes of conventional construction, with a handle, handle or the like and one understood with the bristle holder covered with bristles, but also bristle elements of any kind in which for example, the bristles made of plastic melting one end into a bristle strip, Bristle pack or the like summarized are. For feeding the bristles to the bristle manufacturing station are basically two processes known. On the one hand, the bristle bundles can be in the form of a Endless strand fed and only immediately at the Manufacturing station, if necessary after manufacturing the bristle goods can be cut to the desired size. To the others can work with so-called short cuts become, i.e. the bristles are already in front of the production station to the desired size, if necessary with machining allowance, cut and then the cut ones Bristles are fed to the production station in bundles. The invention is concerned only with the latter Technology.

When processing bristles cut to length will be roughly parallel to each other in one shaft-like magazine, which is usually stored two parallel ones arranged approximately at the distance of the bristle length Has walls. In the lower area of the Magazines are in one wall or several holes through which the bristles are removed in bundles can be. Bundle grippers in the form are used for this of tubes that can be inserted into the magazine through the opening are immersed in the bristle stock and at the same time one corresponding to its free cross section Separate the number of bristles from the rest of the bristles. The immersion depth is usually somewhat less than the bristle length. After pulling out the bundle gripper the magazine becomes what is in the bundle gripper and this bristle bundle protruding outwards brought to the manufacturing station.

In this way of forming and picking up bristle bundles there are several problems. When retracting the Bundle grippers in the magazine are placed on the rim of the mouth bristles hitting the bundle gripper across to its direction of movement outwards or into the bundle gripper displaced into it or axially in front of it Bundle gripper pushed here. By the former The bundle gripper takes a different effect Number of bristles on so that the bundle is different Have density. When axially moving the Bristles lay on the opposite magazine wall um, so they are turned or rolled up there with the result that when these bristles on the next Operation to be included in a bundle, into one irregular protrusion of the bristles on the bundle gripper lead or are unusable due to deformation. These malfunctions, recognized early on by the experts, has been attempted to fix that Bundle grippers cut diagonally at their mouth opening are (DE 28 49 510, 29 22 877, US 3 471 202). At in this embodiment, the edge of the mouth of the bundle gripper occurs not on his during the entry movement entire scope, but successively with sub-areas its extent in the bristle stock. Because the rim of the mouth nevertheless has a finite thickness, can be do not completely eliminate the aforementioned malfunctions. The disadvantage here is in particular that the bristles mainly due to the sloping mouth opening one side and thus the degree of filling fluctuates greatly.

The other and mainly practiced version shows a bundle gripper with a muzzle edge, the runs perpendicular to the bristles in the magazine and in which the outer wall is conical towards the edge of the mouth is tapered so that the rim of the mouth is ideally a is a linear edge. So the probability that the bristles are axially displaced through the mouth edge are severely restricted (DE 23 35 468, 25 11 661, 26 46 048, 28 00 146, EP 0 159 996, US 3 563 609). Nevertheless, there are also disturbances to the aforementioned Art.

It can also happen when the bundle gripper is pulled out Disruptions come when not all of them are covered Bristles remain in the bundle gripper, rather in Magazine get stuck due to friction or but are partially pulled out of the bundle gripper. This applies especially to the bristles on the edge. The reason for this may be that the filling is too loose or else the fact that the bristles are not all on the Mouth opening opposite end of the bundle gripper concern, i.e. themselves with different lengths located in the bundle gripper. One tries that among other things counter that the opposite of the bundle gripper Wall designed as a spring-loaded piston is a cross section corresponding to the bundle has and when retracting the bundle gripper in the direction of entry backs away, those caught by the bundle gripper So bristles compared to the bristle supply in the direction of entry can dodge. When pulling back the bundle grippers the piston is adjusted and so the bristles track along the same length in the bundle gripper (US 3 563 609). Apart from the fact that such a magazine is expensive to build there may be malfunctions in particular at the transition between the piston and the magazine wall come.

Another possibility is seen in this (DE 23 35 468), the bristles when retracting the bundle gripper compact by using the bundle gripper on the inside Has narrowing that is either on the middle axial Length or is arranged at the mouth opening. In order to may like to even out the degree of filling of the Bundle grabs can be achieved, but this will be done with others Disadvantages bought. So the bundle gripper will due to the increasing frictional forces to the bundle size between the bristles not even in depth to fill. There is also a risk that due to this increased frictional forces in the peripheral area Bristles protrude further on the opposite The magazine bottom can be pushed on and bent over.

Another measure to remove the bristles from the Separating the stock cleanly consists of the bundle gripper is provided on the outside with bumpers, whereby the frictional forces between the separated bristles and the bristle stock should be reduced (DE 23 35 468). It has also been recognized that the bristles if possible within the magazine in a uniform, should be in a loose pack. To achieve this, are bristle-parallel internals inside the magazine provided (EP 0 289 676), which on the one hand is part of the Pressure of the bristle stock above the bundle grippers record, on the other hand in the area of the bundle grabs should ensure a loose pack. Here however, there is a risk that the pack in the area of Bundle gripper is completely uneven.

When pulling out the bundle gripper with the separated one Bristle bundles can have bristles adjacent to the bundle gripper moved in the direction of extension, if necessary off be pulled out of the magazine. You then lead at next operation to troubles. It should therefore Bristle ends on the entry side if possible in one level. Similar effects occur when driving in the bundle gripper by moving the bristles towards the opposite Side to be moved. To avoid this has been proposed (EP 0 289 676), which the Magazine wall opposite entry side as swinging Tapping plate form the ends of the bristles about axially and the entire area in the Bundle grippers lying on the opposite bristle stock Magazine wall shows up. The should also Bristles in the bundle gripper are tapped into them will. On the one hand there are individual protruding bristles due to their flexibility in the axial loading lay slightly in front of the other bristle ends and furthermore due to the emergence on the opposite Wall the bristles can also be deformed there herewith the described failure possibility only insufficiently removed.

Finally, any malfunction occurring on the magazine, the bristles protruding at different distances on the bundle gripper or lead to a fluctuating degree of filling, also in the subsequent manufacture of the bristle goods adversely affect. This is especially true when if the bristles by a thermal process such as Welding, melting, injection or the like, connected to the bristle carrier or to a bristle element be shaped.

The invention is based on the object at the outset to further develop said device so that achieved a uniform filling level in the bundle gripper and also when entering the magazine and when Extending the bundle gripper adjacent to the bundle gripper Bristles are not affected.

The solution of the invention task is that the Bundle gripper is driven to rotate about its axis.

Due to the rotational movement, which is uniform, intermittent or oscillating can be radial forces effective between the bundle gripper and the bristles, the on the one hand the loosening of the bristles when running in the bundle gripper in the magazine support, on the other hand reduce the frictional forces between them. This will make the degree of filling even reached and on the bristles near the bundle gripper acting axial forces for the axial displacement of the Bristles lead, diminished.

The transfer of the bristles from the magazine into the bundle gripper is further improved in that the bundle gripper on the inside from the mouth opening a short axial length and then extended an axially parallel over most of its axial length Wall forming an opposite the mouth opening has a larger internal cross-section.

This embodiment is based on knowledge from that when the bundle gripper is moved into the magazine neither a thinning, nor in particular a compression of the Bristle packing should take place to avoid fluctuating friction across the bundle cross section and in immediate neighborhood to this in the bristle stock avoid. It is therefore assumed that a bundle gripper whose cross-section at the mouth opening corresponds to the desired cross section of the bristle bundle, in particular, therefore, does not compress the bristles that are picked up. So when pulling in the bundle gripper First, the one that loosely fills the desired cross-section Number of bristles separated from the bristle supply. The bristles have then due to further retraction of the widening cross-section the opportunity to expand so that on most of the axial Length of the bundle gripper no forces on the bristles are exercised and therefore not uncontrollable Frictional forces between the bristles can be effective. In other words: the cross section of the mouth opening determined in connection with the packing density of the Bristles in the magazine the number of bristles per bundle. On the bristles picked up in this way then act a further retraction no external forces. In Connection with an approximately linear edge on Opening edge gives the further advantage that too to the bundle gripper remaining in the magazine Do not apply any forces to immediately adjacent bristles can, especially not those that lead to an axial Displacement of the bristles could result.

Another embodiment is characterized by this from that the bundle gripper on the inside a different from the Mouth opening extending over a short axial length Axially parallel wall to which the Cross section widening, continuous curve follows.

The bundle gripper can basically be any Have a cross-sectional shape, for example circular, oval, polygonal or the like. The mouth of the mouth continuous curve leading to expansion be a straight or a convex curve. In the first case connects to the short axially parallel separation section a conically widening section and on it again over most of the axial length axially parallel wall section.

Another embodiment is that the bundle gripper on the inside an axially parallel over the entire length extending wall and that within the bundle gripper a mandrel is arranged in the axis of the mandrel a short length in the area of the mouth of the Bundle gripper a thickening with an axially parallel contour and at its free end protruding from the bundle gripper has a taper.

In this embodiment results a hollow bundle. Here too it is ensured that the bristles when retracting the The bundle gripper cannot be compressed. First drives the thorn with its leading taper in the bristle stock and displaces the bristles outwards. Hereby, their packing density is inside the magazine not or only slightly influenced. Only those Bristles freely in the annulus between the orifice and thickening of the mandrel can occur in bulk in the bundle gripper and can then radially expand and loosen after thickening.

As already indicated at the beginning, are arranged on the outside Deflectors known (DE 23 35 468), but they are only effective after a certain entry depth. In contrast it is proposed according to the invention that the bundle gripper on the outside in direct connection to the Mouth opening a deflector for the separated Has bristle bundles of adjacent bristles in the magazine, by the outer wall including the taper in a steady curve up to a maximum and then removable wall cross-section and then attached is axially parallel over most of the length.

The bristles adjacent to the bristles to be separated from the supply Bristles are thus at the beginning of the running-in process Bundle grabs increasingly and continuously to the outside displaced and can thus the separation process, in particular the bristles lying outside in the bundle no longer influence vigorously. Due to the deflector effect at the beginning of the running-in process it is also avoided that the bristles adjacent to the separated bundle axially be acted upon and ousted.

The above measures can still be supported be that the bundle gripper on a short Length in the area of the mouth opening on the outside Axially aligned profile has. The profile is preferably from the circumference of the bundle gripper equidistant troughs formed.

As a result, the radial deflector forces when entering of the bundle gripper is reinforced and in different ways Extent to the individual bristles that make up the bundle gripper surrounded in the magazine, brought to effect.

The training is advantageously made such that the Troughs have a part-circular cross-section. It can be provided that the troughs are formed in this way are that they are on the edge of the circular mouth opening leak.

Another embodiment is characterized by this from that the bottom of the troughs face down towards the mouth opening tapered conical surface. Transfer to the previously described embodiment means this is that the conical surface at the edge of the mouth opening runs out, this in a plane perpendicular to the axis of the bundle gripper.

Another embodiment stands out characterized in that the conical surface on which the bottom of the Troughs lies, which is formed by the mouth opening Penetrates cylinder surface so that the edge of the mouth opening is crown-like.

In the aforementioned embodiment, the Advantage that the edge of the mouth does not open its entire circumference at the same time on the ends of the Bristles in the magazine, but this process is "stretched" in time, namely to the period which the bundle gripper needs to match that of the axial Corresponding depth of the crown-like profile of the opening edge Way to go.

It is also provided that the mouth opening opposite end of the bundle gripper has narrow channels connected to a vacuum source are. The pressurization of the bristles at its rear end in the bundle gripper is in itself known (DE 28 49 510). However, it can do its job there insufficiently fulfilled, since the bundle gripper on its Mouth opening is cut obliquely with the result that an increasingly narrowing free one during the running-in process Cross section remains open and there due to the negative pressure an air flow with constantly during the running-in process increasing flow velocity is present can lead to the last ones entering the bundle gripper Bristles in front of the other bristles in the bundle gripper be drawn in, so in the final state none Uniform bristle protrusion on the bundle gripper is guaranteed.

The bristle bundle picked up by the bundle gripper must be on be handed over to the production station. This can be done happen that the bundle gripper at the same time as a means of transport serve and the bundle directly at the manufacturing station passed and the attachment of the bundle on Bristle holder is made when the bundle is still located in the bundle gripper (DE 26 46 048, DE 23 35 368). In another version (EP 0 149 996, DE 28 08 966) is a termination within the bundle gripper forming piston provided for ejecting the bristle bundle, the bundle gripper along its entire length has a constant cross section. Instead is provided as part of the training according to the invention, that the piston has a larger internal cross section of the bundle gripper has a corresponding cross section and within the bundle gripper of the wall thereof closely fitting at most up to the approach of the mouth opening leading steady curve is slidable.

As is known per se (DE 23 35 468) to form hollow bundles in the axis the bundle gripper arranged a thorn that at the same time the previously described cross-sectional formation can be. In this case, the piston is on the Mandrel guided to push out even with a hollow bundle of the bundle from the bundle gripper.

To further reduce that when the bundle gripper is retracted forces acting on the bristles is preferred the bundle gripper and the thorn on all with the bristles surfaces that come into contact with smooth walls, e.g. polished or coated with a sliding material.

The bundle gripper can, as is also known per se, as a holder for the bristle bundle during its further processing, if necessary also as a means of transport to the Serve manufacturing station.

Devices are also known (DE 28 49 510), where a guide with at least one guide channel is present in the bundle of bristles during manufacture the bristle goods are held. This is from Bundle gripper bristle bundles picked up on the guide channel delivered to processed at the manufacturing station to become. Furthermore, one stands out such device in that the one Bundle gripper inserted into the magazine with the bristle bundle separated from it in the retracted Position remains and the bristle bundle by means of Piston to the opposite side of the magazine in the guide channel of the guide arranged there displaceable is.

With this training, this is the bristle stock separated bristle bundles only in one direction, namely moving in the direction of entry. The bundle gripper carries along the picked up bristle bundle on the entry side opposite side of the magazine. It does not apply thus the pulling back of the bundle gripper and the itself resulting malfunctions (taking bundles from the bristle supply, bristles get caught Bristle bundle etc.). Even when handing it over to the production station the bundle moves by means of the piston always in the same direction.

In a further embodiment it can be provided that the guide is designed as a holder for the bristle bundle and the bundle of bristles can be fixed in the guide. The bristle bundle passed from the bundle gripper to the guide is also fixed in the leadership to get it in to bring a reproducible manufacturing position or to keep in this.

For this purpose, the guide can have a cross section, for example of the guide channel narrowing and the bristle bundle have clamping device.

Another embodiment is emerging characterized in that the leadership or another leadership has a plurality of guide channels, at least in the area of the exit end of the bristles at an angle to one another are arranged and in which the bristle bundles at the transfer to one of your desired positions at the Bristle goods corresponding position are deflectable.

In this embodiment, the bundle from the Bundle gripper directly into the piston Guide channels inserted at the production station and at least in the area of its fastening-side end their original axis are deflected. To this The bundle can be placed in any angular position brought to each other and / or to the bristle carrier.

In another embodiment it can be provided that at a plurality of bundle grippers the pistons different Show end positions in the bundle grabs and the Bundles correspondingly different distances into the guide channels insert to bristle bundles of different lengths to get on the bristle goods.

In this embodiment, the guide channels different protruding bundle ends in cut off a common plane, so that in the Guide channels and, if applicable, the bundle grippers Bundles of different lengths are created, which are then attached to the trimmed end to be connected to the bristle holder. In this way, the user-side envelope surface can be Contour the bristle ends as desired.

The two aforementioned embodiments can be combine with each other in that the bristle bundle by means of the pistons in a first guide with formation of a protrusion on the opposite side is different pushed far in and the excess cut off and that before the interface a further guidance with at least on the opposite Retractable side guide channels into which the bundles of bristles can be inserted.

With a device of the aforementioned type so vary bundle length and bundle position at the same time. In both cases it is an advantage if the bristle bundle with their ends opposite the pistons through the Guide channels can be pushed through and by means of the protruding ones Ends are attached to a bristle holder.

In the aforementioned embodiments can also be provided be that after retracting the bundle gripper in the magazine and before pushing out the bristle bundle by means of the piston the guide or the bracket with the guide channel in front of the mouth opening of the bundle gripper is retractable.

Another design option is that the leading face of the piston for contouring the ends of the bundles of bristles differ from the plane Has contour.

This way the bristles can be within a bundle concave or convex at the usage end or be contoured in some other way so that in connection with the aforementioned embodiments according to the invention trained device for manufacturing any contours on the usable area of a brush can be generated.

As already indicated at the beginning, is for the flawless and trouble-free removal of the bristles or for formation of bundles with the same number of bristles the packing density the bristles of importance in the magazine, which in particular must not be too high. It is therefore provided that the bottom of the magazine Floor is designed as a vibrating floor the bristle supply or a part of it loosening vibration is displaceable.

With this training, the static friction or Attractive forces due to static charge between the individual bristles largely eliminated and the Bristles - similar to this when storing free-flowing Goods are known - as it were fluidized. This gives a relatively loose pack of bristles inside the Magazine so that when the bundle gripper is retracted the Significant danger of axial displacement of bristles is reduced and especially the bristles largely can be pushed to the side without force. Also is the probability of an equal number of bristles significantly increased per bundle.

While in the known devices for alignment a tapping plate is provided at the ends of the bristles, which leads to the difficulties mentioned at the beginning instead provided that the vibratable Wall section parallel to an opposite wall of the magazine is arranged at a distance from it, which is slightly larger than the length in any vibration position the bristles in the magazine.

This design ensures that the vibrating wall section only those bristles axially acted upon, for example, when retracting the Bundle grabs - over those otherwise lying on one level Stick out bristle ends. In particular, it is avoided that the bristles against the opposite wall of the Magazine be compressed because the shortest distance between the fixed wall and the swinging wall section in any case, is always greater than the bristle length.

The aforementioned requirement can be carried out in an expedient manner be realized in that the vibratable Wall section adjustable stops for compliance assigned to the distance from the opposite wall are.

The equalization of the bristle pack within the Magazine at least in the area of the bundle grippers, as well ensuring the fluidized condition of the bristles serves the further measure, according to which across the bristles and above the bundle gripper in the magazine retractable compartment is provided that the Weight of the bristle stock stored above the bundle gripper records.

The compartment is opened immediately after the Bundle gripper and the bristles sliding into it Magazine retracted with the result that only the one below bristles located by the vibration of the bottom of the Magazine are loaded and also defined relationships regarding the bristle pack only in the area the bundle gripper must be generated.

The aforementioned effects can still be supported be that the compartment in the retracted position at least while the bundle gripper is retracting into the Magazine can be raised.

In this embodiment, the is in the range of Bundle gripper existing bristle stock in terms of load completely from the bristle stock above separated at least during the removal process.

The device according to the invention permits production of bristle goods in a particularly simple manner and high quality. For example, as is known per se, the bristle bundles at one end in the area melted the mouth opening of the bundle gripper and with one likewise melted at least in some areas Bristle carriers brought together, so can this method with the device according to the invention thereby improve that the bundle with the mouth opening of the bundle gripper pushed flush and into the bundle gripper are melted into it and that at Bringing together bristle bundles and bristle carriers Bundle gripper placed tightly on the bristle holder and the bundle of bristles is pressed by means of the piston.

This process ensures that the melting range the bristles on the cross section of the bundle gripper is limited, so the melt is not laterally can dodge. When merging with the bristle holder will the formation of beads or the like avoided by displaced enamel.

This process can still be optimized by that the bundle gripper with its mouth opening - including the melt of the bristle bundle and bristle carrier - is placed tightly on the bristle carrier.

This also ensures that the enamel is "caught" on the bristle carrier and not can dodge to the side. This results in a clean bundle connection on the bristle holder. Otherwise, can the mass to be melted is reduced to a minimum will.

The use of the device according to the invention results in procedurally, the possibility of that on the bristle carrier with a pre-formed recess at least one protruding from the bottom of the recess Is formed that the bristle bundle with the Mouth opening of the bundle gripper butted flush and in the bundle gripper into it, forming a recess is melted that at least the projection in the Melted near the surface and the bundle with its melted depression by means of the piston pressed into the recess and on the projection becomes.

In this embodiment, the melt or Fusion connection of bristle bundle and bristle carrier in the bristle carrier moved in, so that also this way a clean bundle finish on the bristle carrier with sufficient fastening length of the bundle results on the bristle holder.

In the known devices it has also been shown that the bristles on the entry side of the bundle gripper through the leading edge of the mouth of the bundle gripper are often split. This happens in particular when, as desired, the rim of the mouth formed to an approximately linear edge is. This splits individual bristles avoid cutting the bristles to length deburred at least at one end and with the deburred end facing the bundle gripper into the Magazine.

When cutting the bristles to the desired length are formed depending on the type of plastic and the one used Cutting tool burrs of different dimensions at the interface. These are obvious responsible for ensuring that when the bundle gripper is retracted individual bristles split. With the Deburring according to the invention is the splitting effectively avoided.

In connection with the aforementioned measures is also beneficial if the bristles cut to length at least at one end, the later use side End, machined and with the machined ends stored in the magazine aligned to one side will.

While usually the bristles only after they are attached machined on the bristle carrier, for example rounded, the invention sees this processing before storing the bristles in the magazine. Such Processing is in the older patent application DE-A-40 06 352 described by the applicant. It leads to one opposite the known process more uniform processing the bristle ends. This process can be done with the Combine the aforementioned method in that a separate deburring can be omitted by using the bristles be stored in the magazine so that their machined ends on the entry side of the bundle gripper are located. This eliminates the need for separate deburring and it will the end processing of the Bristles at the same time in terms of process technology the bundle formation is used to split the bristles to avoid.

The exemplary embodiments according to FIGS. 1-15 serve only for explanation.

In Figure 1, the lower part of a magazine 1 is for Length of cut bristles 2 recognizable. The bristles 2 are stored in parallel in magazine 1. The magazine 1 is shaft-like and has parallel Walls 3, 4 and a floor 5. The distance of the Walls 3, 4 is slightly larger than the length of the bristles 2. The magazine is filled from above and the weight of the incorporated bristles from the bottom 5.

On one side of the magazine - assigned to wall 3 - a group of bundle grippers 6 is arranged which a movable carrier 7 sit. The bundle grippers 6 are tubular, for example cylindrical. However, you can also use any other cross-sectional shape exhibit. The rear end of the bundle grippers 6 is formed by a piston 8 each. The pistons 8 sit on a piston rod via a piston rod 9 10, which together with the carrier 7 of the bundle gripper 6 Movable in the axis direction shown in dashed lines is, but additionally movable relative to the carrier 7 is so that the pistons 8 dip into the bundle grippers 6 can.

The bundle gripper 6 can with the carrier 7 and the carrier 10 can be moved up to the magazine. The wall 3 of the magazine 1 has openings 11, the cross section of which corresponds to the outer cross section of the bundle gripper 6. By these openings 11 can the bundle gripper 6 in the magazine 1 can be retracted. In doing so, each bundle gripper 6 a number of bristles 2 each forming a bundle separated from the stock stored in magazine 1 and picked up by the bundle gripper 6 during the retracting movement.

The opposite wall 4 of the magazine 1 points in the area the bundle gripper 6 has a wall section 12, that vibrates in the direction of extension of the bristles is relocatable. The wall section 12 serves to store the Bristles 2 in the work area of the bundle grippers 6 to move towards the wall 3 to hold it on her to butt the wall section 12 end flush. The wall section 12 is arranged so that it in each Vibration position from the opposite wall 3 a distance which is little larger than the bristle length. This can be seen, for example, from those in FIG Limit stops 13 are ensured.

The bottom 5 of the magazine 1 is, as is also schematic indicated, vibratable, the direction of vibration is approximately vertical. This will make the stored Bristles 2 vibrated to a uniform packing density to achieve. In conjunction with that described below Detail of the device are the bristles 2 by means of the bottom 5 "fluidized" in a kind of vibrating state.

Above the work area of the bundle grippers 6 Compartment 14 arranged, as can be seen in Figure 2, are designed as narrow lances and in line Openings 15 in opposite end walls of the magazine 1 are retractable. You take the weight of the above of the working area of the bundle gripper 6 Stock of bristles. To the loosening effect the vibrating floor 5 on the in the work area Bundle gripper 6 lying bristles come fully into effect to let, the compartment 14 can also be lifted and be lowered. You become the bundle gripper before each working stroke 6, that is to say roughly in the operating state shown in FIG. 1 retracted and raised. In this position the compartments remain at least until the bundle grippers 6 have completed their work stroke. Subsequently they are extended so that after extending the bundle gripper 6 the bristles from the upper area of magazine 1 can slide.

On the side opposite the bundle grabs a guide 16 with parallel guide channels 17 is arranged, the one with the bundle grippers 6 on the opposite Align side. The guide 16 is also a device 18 associated with the embodiment shown is designed as a clamping device. The clamping device 18 consists of a plate-like slide 19, which in turn is provided with openings 20, the cross section about that of the guide channels 17 or the inner cross section the bundle gripper 6 corresponds. The slide 19 is transverse slidable to the axis of the guide channels 17 so that the Openings 20 in a offset to the guide channels 17 Position can be brought.

The mode of operation of the device according to FIGS. 1 and 2 is described below:

In the starting position shown in Figure 1, in which the Compartment 14 the bristles in the upper region of the magazine 1 record and both the bottom 5, and the wall section 12 are vibrated, the bundle grabs 6 by means of the carrier 7 through the openings 11 retracted into the magazine and separate a number each from bristles from the bristle stock, which then each to form a bundle. Do the bundle grippers 6 have theirs End position reached, for example, the carrier 7 runs against the side wall 3 of the magazine 1, the Wall section 12 extended laterally, the guide 16 the exposed ends of the bristles are brought up, so that the bundle gripper 6 with their front end of them facing end wall of the guide 16 about. It then the bristle bundles located in the bundle grippers 6 by means of the piston 8 by moving the piston carrier 10 pushed out of the bundle grabs and inserted into the guide channels 17 of the guide 16. Subsequently, the slide 19 from that shown in Figure 1 Move the position transversely to the guide channels 17, so that the bristle bundles located in the guide channels 17 are clamped fixed. Then the bundle grabs move 6 with the piston 8 again in the starting position according to Figure 1 back. Already towards the end of the entry movement Bundle grippers 6 can make the lance-like dividers 14 are pulled out of the magazine so that the bristles 2 slide down. Furthermore, the guide 16 moves after delivery the bundle likewise again in that shown in Figure 1 Position and continues the wall section 12 again in its position completing the wall 4. The bristles 2 in the work area of the bundle grippers 6 are by means of of the vibrating wall section 12 flush again encountered.

Figures 3 and 4 show partial sections of an embodiment of the bundle gripper 6. At the front end 21, with which the bundle gripper dips into the magazine is the outer wall pulled inwards while reducing the wall thickness, preferably such that the mouth opening 22 a has approximately linear opening edge. This is particularly recognizable in FIG. 4. The free cross section A of the bundle gripper 6 in the area of the mouth opening 22 determines the cross section of the bundle in a packing density, as in the lower area of the magazine 3 is present. In the embodiment shown the bundle gripper 6 this cross section A over a short axial length C. The inner wall deviates from the cross section A. 23 of the bundle gripper on a likewise comparative short axial length D in a steady curve, if necessary a straight line, to a larger inner cross-section B back. This larger inner cross section B has the bundle gripper over most of its axial Length as shown in Figure 3.

In the exemplary embodiment shown in FIG Bundle gripper 6 at its front end 21 additionally provided with a deflector 24, which by exclusively outside enlargement of the wall thickness has been obtained is. The deflector 24 thus forms one on the outside Thickening in the axial direction of a continuous Curve is formed, which at the mouth opening 22nd starts and extends over a short axial length, to then go back into the smaller outside diameter of the bundle gripper 6. Furthermore, this one Embodiment of the bundle gripper 6 on the rear the piston 8 lying space 25 connected to negative pressure. Around this also in the bundle receiving space 26 to effect, the piston 8 with a variety provided by holes 27 with a very small diameter. The diameter is particularly smaller than that the bristles. The negative pressure in room 25 supports the Inclusion of the bristles in room 26. This can be done in this way be that the piston 8 in the starting position (see Figure 1) has moved forward and accordingly the retraction speed of the bundle gripper 6 returns, so that all bristles separated from the bundle gripper support be sucked in.

Figure 6 shows a modified compared to Figures 1 and 2 Execution of the device, the magazine 1 however is not shown for the sake of clarity. With this The embodiment is the front end face 28 of the Piston 8 dome-shaped, so that the bundle gripper 6 bundles 29 picked up on the end face 28 of the piston 8 facing end is contoured by when pushing the bundle 29 out of the bundle gripper 6 the bristles 2 are shifted axially to one another within the bundle will. Furthermore, the pistons can be different long piston rods 9 (see middle piston 8 in figure 6) be arranged or perform strokes of different lengths, so that when the bundle 29 is handed over from the bundle grippers 6 to the guide 16, the bundles 29 at their ends on the one hand contoured, for example the ends on one spherical surface, on the other hand the bundle 29 after transfer to the guide channels 17 of the guide 16 project differently over the leadership. Thereby So can the envelope of all bundles of one Contour bristle trimmings.

In the exemplary embodiment shown, the bundles 29 on their the guide 16 on the opposite side projecting ends by means of a cutting device 30 cut flush. Then there is the further possibility after extending the cutting device 30 in front of the Guide 16 to retract another guide 31, the Guide channels 32 not or only partially with the guide channels in the guide 16. In particular, as can be seen in the outer channels 32, below run at an angle to the guide channels 17. By Can push on the bundle from the left in Figure 7 the bundles then at least partially at the opposite end be deflected into an angular position. In this position they can be attached to a bristle carrier 33 (FIG. 8) be so that the schematic shown there Bristle trim results in the bundle 29 at an angle to each other are employed, the end of each bundle is contoured and the ends of all bundles in turn in one contoured envelope surface.

FIG. 9 shows another embodiment of the bundle gripper 6 shown. It is used to make bundles with an axial channel free of bristles. To this Purpose is a mandrel 34 in the axis of the bundle gripper 6 arranged, which projects beyond its mouth opening 22 End is tapered to a rounded tip 35. The piston 8 is guided on the mandrel 34. When entering this bundle gripper 6 in the bristle stock Bristles out from the center by means of the mandrel 34 displaced on the outside, so that a hollow bundle is formed. Such Bristle bundles are used, for example, for applicators required, as shown schematically in Figure 10. Such application device 36 has at least one channel 37 through which the medium can escape from the device. The application device 36 is equipped with a bundle 38, that is produced with a bundle gripper 6 according to FIG. 9 and has a channel 39 in the center, for example extends the channel 37 of the device.

Figure 11 shows a modified from Figures 3 and 4 Embodiment of the bundle gripper, which at the same time in the sense the embodiment of Figure 9 can be used. The bundle gripper 6 according to FIG. 11 is in the area the narrowest cross section provided for the mouth opening 22 (cf. Section C in FIG. 4), in that the Bundle gripper 6 inside one over the entire axial Has length axially parallel wall. In the bundle gripper 6 a mandrel 34 is in turn arranged, but on its front end a thickening 40 with again axially parallel Has contour. In the bundle gripper 6 protruding Area, the thorn in turn tapers to a rounded Tip 41. This ensures that when entering of the bundle gripper in the bristle supply initially the bristles to be pushed outwards and only the ends of the Bristles located in the area of the mouth opening 22 can be gripped by the bundle gripper 6 without compression the bristles take place.

Figure 12 shows the process in a schematic representation in the production of, for example, a brush or the like. Again, they are those with reference to FIG. 1 described components available and with the same Provide reference numerals. In addition, the magazine 1 opposite side of the guide 16, a holder 42 can be seen, which receives a bristle carrier 43. Still is a heating device 44 is shown, which between the guide 16th and the bristle carrier 43 to which the bristle bundles are to be attached are retractable. The bundle gripper 6 moves along retracted piston 8 into magazine 1, separates there a bundle 29 from the bristle stock (Figure 12 b)). After the swingable wall section 12 moves away the guide 16 to the exposed ends of the bristles. The piston 8 is moved into the bundle gripper 6 and pushes the bristle bundle 29 on the opposite Side of the magazine 1 in the channel 17 of the guide, wherein the bundle 29 on the opposite side the guide 16 towers (Figure 1 c)). Then the heater 44 driven in front of the free end of the bristle bundle 29 and at the same time the bristle carrier 43 with the holder 42 to the Heating device moved up. The bundle 29 is on his End and the bristle carrier 43 on the heating device 44 facing side melted, for example forms a thickening at the end of the bundle. After driving out the heater 44 and moving up the bristle carrier 43 penetrates the end of the bundle into the melt of the Bristle carrier 43 a (Figure 12 e)). After a short time Cooling, the components of the device are moved apart, as shown in Figure 12 f). The finished one Brush 45 can then be removed.

In the embodiment shown in Figure 13 is again a bundle gripper 6 with piston 8 can be seen, the too its mouth opening 22 tapers in a similar manner as has already been described with reference to FIG. 3. There is also a heating device 46 and a bristle carrier 47 reproduced in sections. In this embodiment the bundle gripper 6 is used directly for production of bristle goods. So the device needs opposite the embodiments according to Figures 1, 2 and 12 no guidance 16. The heating device 46 points to the bundle gripper 6 facing side a heating mirror 48 and on a heating piston 49 on the opposite side. The bundle gripper 6 takes up the bristle bundle 29 so that the free Close the ends of the bristles flush with the mouth opening 22. This can either be on the occasion of the removal from the magazine or by pushing the bundle open 29 or the bristle gripper 6 on a stop plate can be achieved. In this position (Figure 13 a)), in which the bundle 29 at its rear end through the Piston 8 is supported, the heating device 46 with the heating mirror 48 moved up to the opening edge 22 and at the same time the bristle carrier 47 on the heating piston 49 moved up. The bundle 29 is at its inside the Melted bundle gripper 6 lying free end, as can be seen at 50, by pushing of the piston the shortening that occurs when melting the bristles can be adjusted if necessary. At the same time becomes the bristle carrier 47 on its surface melted in areas, as shown at 51. The heating piston 49 is advantageously designed such that that the resulting melting area 51 has an outer outline has that is smaller than the cross section of the mouth opening 22 (Figure 13 b)). After a short drive back of the bristle carrier 47, the heating device 46 is moved out and the bundle gripper directly onto the surface of the bristle carrier, the mouth opening 22 on a non-deformable area of the bristle carrier hits (Figure 13 c)). This will melt caught on the circumference and cannot penetrate to the outside. In order to obtain sufficient pressure in the melting area, the piston can make a short forward stroke. Then the bundle gripper 6 - if necessary retracting the piston 8 and the in Figure 13 d) bristle goods shown, for. B. a brush.

14 are the same Components of the device as shown in Figure 13. However, a prepared bristle carrier 47 is used here, the one recess 52 for receiving the bristle bundle 29 has. Within the recess 52 is a Projection 53 arranged, but not up to the free Surface 54 of the bristle carrier protrudes. The deepening 52 also has a diameter corresponding to the bundle 29 Narrowing 55 on the surface 54. The In this case, the heating device 26 points to the side the bristle carrier 47 has a hollow heating piston 57, whose inner contour corresponds approximately to that of the projection 53. On the side facing the bristle bundle 29 the heating device 56 likewise a heating piston 58, which is tiered in this case. The heating piston 58 tapers down the steps to its free end. With this Embodiment are the bundle gripper 6, the Heater 56 and bristle carrier 47 moved together, as shown in Figure 14 b). The heating piston 57 of the heater 56 melts the material of the projection 53 and the bottom of the recess 52 at least in near the surface. The bristles immediately of the bundle 29 melted from its end and one inwardly deepened melting area 59 is generated. After moving the heater apart and extending it the bristle bundle 29 and the bristle carrier 47 are moved together, the bundle 29 into the recess 52 penetrates and the melted area 59 of the bristles with the near-surface melt of the projection 53 or the bottom of the recess 52 connects. The connection is, as can be seen from FIG. 15, within of the bristle carrier 47, so that on its free surface 54 no changes occur. Otherwise, the bundle 29 supported laterally by the constriction 55.

16 to 18 is a further embodiment of a Bundle gripper 6 shown. He's on most of it its axial length is cylindrical and outside in the area of its end 21 to the mouth opening 22 tapered towards. The bundle gripper has at the end 21 also a profile 60 on the shown Embodiment of troughs 61 is formed, which in the same distance from each other distributed over the circumference are. The troughs 61 have, as can be seen in FIG. 17 leaves a part-circular cross-section and its bottom 62 lies on a conical surface 63 (FIG. 16), the one has a flatter angle than the conical taper at the end 21 of the bundle gripper. The bottom 62 of the troughs and thus the conical surface 63 run at the edge of the mouth opening 22 off. The bristles 2 'are when the Bundle gripper deflected outward into the magazine while the bristles 2 '' are gripped by the bundle gripper 6.

The bundle gripper 6 is driven rotatably about its axis 64. This can be uniform, intermittent or - as indicated in FIG. 17 with the double arrow 65 - happen oscillating so that the bristles that are in the Troughs 61 arrive, also with a tangential component are acted upon, as is the case with the arrows in FIG. 17 is indicated.

In the embodiment according to FIGS. 19 to 21 the bottom of the troughs 61 on a conical surface 66, the 16, for example the has the same angle of inclination as the conical taper at the end 21 of the bundle gripper 6. The conical surface 66 penetrates the inside of the bundle gripper 6 cylinders formed so that the edge of the mouth opening 22 is profiled crown-like (Fig. 21).
