Definitions
- the invention relates to a method for producing brushes according to the preamble of claim 1.
- An advantageous development of the method consists in that when removing the sheath of the bristle bundle, the sheath and alternatively the exposed bristle bundle section are taken alternately and overlapping in time. As a result, the bundle of bristles is held securely during the entire separation process.
- the invention also relates to a brush manufacturing machine according to the preamble of claim 5.
- Such brush making machines are also already known, e.g. through the FR-A-2 358 126 mentioned at the beginning.
- Such brush machines also have the disadvantages already described in connection with the associated method and there is also an analogous task with regard to the creation of a brush manufacturing machine to a brush machine according to the preamble of claim 5 improve that it is possible to separate sheaths from the bristles therein and to safely remove these sheaths over a longer period of time.
- the grippers expediently have at least two gripping jaws or the like which can be moved approximately radially to the bristle bundle.
- Gripper elements the gripping surfaces of which are possibly adapted approximately to the outline shape or the cross section of the bristle bundle. If necessary, in the bristle bundles which are usually round in cross section, these gripping surfaces can be approximately semicircular.
- the bundle of bristles is then or the like both during the severing of its covering. as well as tightly encompassed during its further transport and held together securely even after its wrapping has been eliminated.
- the holding and pulling gripper can be displaced in relation to the bristle bundle in the longitudinal direction thereof by part of the bundle length.
- the wrapping or the like. can be gripped in this way and pulled back a little by the sliding movement of the holding and pulling gripper, so that a bristle bundle end region is free.
- the removal gripper is approximately coaxial to the longitudinal axis of the bristle bundle and additionally preferably in the direction transverse to the longitudinal axis, for. B. movable towards a bristle magazine.
- the removal gripper can then attack the exposed area of the bristle bundle, pull it out of the casing and, if necessary, to a bristle magazine or the like. Move the bristle storage container.
- the bristle bundles are mounted in the region of the separating device with a vertically oriented longitudinal axis, the holding and pulling gripper initially engaging at the upper end of the bristle tuft and the removal gripper being arranged such that it can be fed from above.
- the casing or the like first shifted down a little by the holding and pulling gripper and then the bristle bundle is pulled up out of the casing; doing so at the bottom of the bristle tuft with the help of a base for this a counter bearing for the bristles.
- a further embodiment of the invention provides that a pressure application device is provided in the bristle magazine, which has pressure elements acting alternately on the bristle supply, and that the greatest distance of these pressure elements from one another corresponds at least approximately to the cross section of a bundle of bristles supplied by the removal gripper.
- the bristle bundles separated from the sheath can thus be introduced into the bristle stock without the bristle stock already in the magazine having to be changed, in particular with regard to the pressurization.
- a separating device 1 shown in FIG. 1 is part of a brush manufacturing machine, in which in particular bristles 3 initially located in a covering 2 are fed to a brush tamping machine, of which only the so-called circular arc divider 4 can be seen in FIGS. 1, 8 and 11.
- the separating device 1 essentially has a gripping device designated as a whole. 1 2 where a holding and peeling claw 6 z 'jm detecting the wrapped bundle of bristles 8, as shown in Fig., As well as for at least partially withdrawing the sheath 2 as shown in Fig. Recognizable provided.
- the gripping device 5 also has a removal gripper 7 with which the free bundle section 9 can be gripped and pulled out of the casing 2.
- the bristle bundle 8 pulled out of the casing 2 is transported with the aid of the removal gripper 7 to a bristle supply 11 located in a magazine 10.
- the grippers 6 and 7 each have two gripping jaws 12, 13 in the exemplary embodiment, which have approximately adapted to the outline shape of the bristle bundle 8, in particular approximately semicircular gripping surfaces 14, as can be clearly seen in FIGS. 9 to 11.
- the holding and pulling-off gripper 6 is accommodated in a lifting frame 15 which overall can be displaced in height relative to the bristle bundle 8 located in the separating device 1 according to the arrow Pf 1.
- Pneumatic lifting drives 16 in particular are provided both for adjusting the gripping jaws 12 and 13 and for adjusting the height of the lifting frame 15.
- a bristle bundle 8 located in the separating device 1 is mounted vertically with respect to its longitudinal extent on a base 17, which in the exemplary embodiment is part of the bottom of a feed device 18 (cf. FIGS. 10 and 10).
- the sheathing 2 is now separated from a bristle bundle 8 in that the coated bristle bundle 8 is first gripped by the gripping jaws 12 of the holding and pulling gripper 6 at the upper end region, as can be seen well in FIG. 1.
- the lifting drive 16 for the lifting frame 15 By actuating the lifting drive 16 for the lifting frame 15, the holding and pulling gripper 6 is moved somewhat downward relative to the bristle bundle 8, the covering 2 being correspondingly stripped off.
- the lifting movement is dimensioned such that the upper bundle section 9, which is free of the covering 2, enables the removal gripper 7 to be gripped securely.
- the lifting movement of the holding and pulling-off gripper 6 could be provided such that the covering 2 is stripped off over approximately half the bristle length.
- the removal gripper 7 in its top position in FIG. 1 is then moved to the bristle bundle 8 until its gripping jaws 13 are located to the side of the free bundle section 9. Then the bristle bundle 8 is gripped at its free bundle section 9 by closing the gripping jaws 13 (see FIG. 2) and pulled out of the casing 2 by raising the removal gripper 7.
- the holding and pulling gripper 6 remains approximately in its closed position during this separating process, but its gripping jaws 12 can yield somewhat radially, which can be achieved by removing the pressure from the lifting cylinders 16.
- the sheath 2 is thus stripped off the gripping jaws 12 without a greater pull-out resistance being present.
- the bristle bundle 8 is held alternately, preferably overlapping in time, by the grippers 6 and 7 that the bristle bundle 8 is held securely in each phase of the separation.
- the removal gripper 7 is also horizontally displaceable, the horizontal guide 19 leading to the magazine 10 in the exemplary embodiment.
- a bristle bundle held by the gripping jaws 13 can thereby be transported laterally from the area of the separating device 1 into the area of the magazine 10.
- the bristle magazine 10 has a pressurizing device with pressure elements 20, 21 which act alternately on the bristle supply 11. This causes an approximately constant supply pressure to the circular arc divider 4.
- the bristle bundle 8 is inserted into the magazine 10 between these pressure elements 20, 21, as shown in FIG. 4. After the bristle bundle 8 has been deposited, it is acted upon and held on the back by the fork-shaped pressure element 20 (FIG. 5). Subsequently, as shown in FIG.
- the finger-shaped pressure element 21 can be pulled out of the bristle supply and then takes over the loading of the bristle supply instead of the fork-shaped pressure element 20.
- the fork-shaped pressure element 20 can then be moved back to a position (FIGS. 7 and 1) until the space between the pressure elements 20 and 21 is sufficient to accommodate the next bundle of bristles 8 separated from the sheath 2.
- 8 shows a top view of the arrangement of the pressure elements 20, 21 in the magazine 10, the discharge end of which opens in the region of the circular-arc divider 4. It can also be clearly seen here that the pressure elements 20, 21 can be displaced both in the longitudinal direction of the magazine 10 and in the disengagement and engagement position.
- Fig. 11 shows a separation device 1 in supervision with an associated double magazine 10 a, in which, for example, bristles of different colors can be entered.
- the removal gripper 7 is arranged displaceably transversely to the longitudinal extent of the magazine 10 a in accordance with the distance between these magazine channels.
- the lifting cylinder 22 is provided as the drive, while a further lifting cylinder 23 is provided for moving the removal gripper 7 from the separating device to the magazine 10 a.
- the Hzite and pull-off gripper 6 located below the removal gripper 7 is not visible in this illustration.
- the feed device shown in FIGS. 9 and 10 serves to feed the coated or coated bristle bundles 8 to the separating device 1. It has a separating device 24 with a combined blocking and transport slide 25 at its feed end. With the separating device 24, the bristle bundles 8 arriving one after the other via a guide channel 26 can be fed one after the other to the separating device 1.
- the locking and transport slide 25 is approximately angular in shape with a locking side 27 and a feed side 28. If the slide 25 is in the release position shown in FIG. 10, the bundles of bristles located in the guide channel 26, which preferably runs at an angle, can slip, the foremost one resting against a stop 29.
- the slide 25 By moving the slide 25 transversely, for which a lifting cylinder 30 is provided here, the slide 25 moves into the blocking position shown in FIG. 9, and it transports the bundle of bristles 8 resting against the stop 29 into the separating device 1. After the slide has been pulled back, the gripping jaws 12 of the holding and pulling-off gripper 6 shown here can grip the bristle bundle 8 or its sheath 2.
- the stripped sheath 2 (Fig. 3) could be removed by compressed air.
- the magazines 10, 10 a often have comparatively narrow receiving channels for the bristle supply 11, the width of these channels being smaller than the diameter of the approximately round bristle bundles 8.
- the bristle bundles are adapted to the shape of the bristle receptacle, in particular to the width of the magazine receptacle channels, during and / or after removal of the sheath 2.
- the clear receiving cross-section of the gripping jaws 13 of the removal gripper 7 in the closed position e.g. be rectangular, the narrow sides at most corresponding to the width of a magazine receiving channel.
- the bristle bundle 8 could also be gradually deformed from its round cross-sectional shape into a cross-sectional shape suitable for a subsequent magazine.
- the receiving cross section of the gripping jaws 12 of the holding and pulling gripper 6 can already have an intermediate shape between the round cross section and the intended delivery cross section of the bristle bundle, and the receiving cross section of the removal gripper jaws 13 can correspond to the final, intended delivery cross section of the bristle bundles 8.
- the holding and pulling gripper 6 and / or the removal gripper 7 can each be designed with a fixed and a movable gripping jaw with respect to their gripping movement which is approximately radial to the bristle bundle 8. This results in a significant simplification, since a corresponding lifting drive is only required for the movable gripping jaw.
- the separating device 1 can also be designed for horizontal mounting of the bristle bundles 8, preferably with a one-sided, end-face stop.
- the embodiment with gripping jaws fixed on one side is then particularly advantageous. It should also be mentioned that the gripping jaws 12 are fixed in the pulling direction and the end stop or the base 17 can be movable relative to it for the partial removal of the casing 2.
- the separating device 1 according to the invention can also be used separately without a feed connection to a bristle storage magazine or, if appropriate, in connection with a material dressing device.
- the separating device 1 according to the invention also in connection with the respectively adjacent devices 18 and 10, has the essential advantage that the transport, the respective transfers and the separation of the casing 2 with comparatively simple means and at the same time high operational reliability even over longer production sections without problems can expire. This is also a prerequisite for the planned, largely largely automated overall production process.
- a double feeding device 18 a for bristle bundles 8 is expediently provided, as shown in FIG. 12.
- bristle bundles 8 containing alternating or optionally different bristles can be fed to the separating device 1.
- the bristles held by the removal gripper 7 are fed to one of the magazine channels 31 or 31 a (FIG. 11), depending on the type.
- the bristles can e.g. differ in color, bristle length, thickness, material, etc.
- the feed device 18 a and the magazine are designed for two different types of bristles. If necessary, these devices could also be set up for more than two types of bristle. Despite this processing of several types of bristle, it is advantageous to use only one separating device 1. The mechanical effort is therefore comparatively low overall even when processing several different types of bristle.
- two feed channels 32 coming from bristle bundle magazines can be seen which are connected to the separating device 24.
- the feed channels 32 and the connecting channel 34 can be arranged obliquely as slides.
