Apparatus for packing a bundle of bristles into a bundle accommodating hole of a support body

The present invention relates to an apparatus for packing a bundle of bristles into a bundle receiving opening of a support body, comprising means for dispensing a bundle of bristles from the bristles and for transporting the bundle of bristles to the tamping tool.

Such devices are known and proven in practice. The tufts of bristles are usually taken out of the bristle reserve by means of a circular beam splitter and fed to the filling tool, where the tufts of bristles are clamped by the advancing tongue and are stuffed together with the anchoring plate or the anchoring ring to the support body, for example a toothbrush body or a broom head. The bundle is received in the hole.

When using natural bristles, such as natural bristles composed of plant raw materials such as coconut trees, fibrous roots, mountain palms, palm fibers, Bahia grass, rice roots or straw, and also in animal products such as horsehair, mountain wool, mane, In wild boar hair or other hairs, there is a problem that each bristles are hooked into each other. If it is desired to remove a smaller tuft of bristles from a larger bristle reserve, the smaller tufts of bristles can only be dispensed from the bristle reserve, since the individual bristles of the bristle bundle held by the beam splitter are left in the bristles The bristles in the reserve are held for a while and the bristles of the bristles of the bristles are thereby bent.

Each bristles of a tuft of bristles may undergo additional bending within the very fast moving circular beam splitter during transport of the bristles due to centrifugal forces acting on the tufts of bristles.

These bending effects also occur in certain artificial materials such as pure nylon.

Due to these bendings, the beam expands from the beam splitting groove towards its free end, and the bundle remains in the beam splitting groove during transport to the stuffing tool. This may result in the filling, not all of the bristle elements being held and carried by the anchoring plate or anchoring ring, such that individual bristle elements remain in the insertion area of the stuffing tool and block the stuffing tool.

It is therefore an object of the invention to create a device of the type mentioned at the beginning in which the bundle of bristles is reliably clamped by the slider or anchoring plate or anchoring ring of the filling tool and prevents the tamping tool from being clogged by the remaining bristles.

The object of the solution according to the invention is to provide a beam ejector that is movable between a beam loading position on the stuffing tool and a retracted release position compared thereto. The beam ejector is used to load the bristles in the region of the tamping tool and thereby eliminate their curvature, so that the bristles are oriented at least substantially straight in the tamping region and all the bristles are anchored during the filling process or The anchoring ring is clamped and carried. This prevents the tamping tool from being clogged by the remaining bristles.

Suitably, the means for separating the tufts of bristles has a circular beam splitter with a beam splitting groove for receiving a bundle of bristles, the circular beam splitter being positionable in the bristles The take-out position on the stock and the split-groove are placed between the transport positions in the region of the stuffing tool.

In order to utilize the beam ejector not only to load the tufts before the tamping tool, but also to push the bristles up to the area of the slider inside the tamping tool, it is expedient for the tamping tool to have a partial insertion for the ejector Void.

Depending on the type of bristles to be treated, it may be sufficient for the beam ejector to be placed next to the tamping tool in its bundle loading position. This enables a structurally simple construction of the device.

For a simple mechanical construction and drive, the beam ejector can be supported for linear movement.

However, it is also possible that the beam ejector is supported to be movable along a circular arc track. In this case, the drive for the circular beam splitter can be coupled to the drive for the beam ejector, wherein the coupling can be mechanical or electronic. A common drive can be provided for the circular beam splitter and the beam ejector, which enables a simple and economical construction of the device.

In order to better load the tufts of bristles, which generally have a circular cross section, and press them to the desired position, it is advantageous for the beam ejector to have a concave loading end.

In practice, a tamping tool constructed as a slider tool is known. The various parts of the slider are fixedly connected to each other and advanced and retracted together. Thus only one drive device is required, which can have, for example, a double eccentric. Disadvantageously, however, when the anchoring ring or anchoring plate is inserted into the area of the filling tool through the tuft of bristles, the anchoring ring or anchoring plate is guided on only one side when the bristle bundle is inserted. Therefore, the insertion area for the tuft of bristles must be forced to be less than the length of the anchoring plate or anchoring ring in the direction of insertion. The problem arises when the bristle bundles comprising the individual isolated bristle elements are strongly bent, ie the individual bristle bundles are not clamped by the anchor and remain in the stuffing tool.

An improved inventive concept is therefore provided in that the anchoring wire or the anchoring ring to be inserted together with the tuft of bristles is provided with a guide element which can be arranged in the region of the bundle transport opening on the bundle transport side of the stuffing tool. The region of the filling tool in which the tufts of the bristles are inserted can be closed by the guide element in such a way that the anchor is guided over the guide element during filling and that the individual slanted bristles are prevented from escaping into the open area and thus The anchor is not completely clamped and thus remains in the stuffing tool.

In general, such a two-slider tool in which a portion of the slider is moved such that the area in which the bundle of bristles is first transported is closed. The advantage here is that the anchors (plates or rings) are always guided on both sides when stuffed. However, in these two-slider tools, two drive units and at least two double eccentric wheels are required. When the bristle bundle is strongly bent, the individual bristle elements may prevent the slider from closing in the bristle bundle delivery area or individual bristle elements may be pinched, which may result in damage to the slider.

The bundle of bristles is oriented straight by the beam ejector according to the invention so that the slider can be closed without clamping the individual bristles or preventing or preventing the closure of the slider.

The guiding element can preferably be arranged on the beam ejector. There is therefore no need for a separate drive for the guiding element.

The beam ejector is preferably resiliently supported to prevent the bristle bundle from being crushed due to excessive loading forces through the beam ejector.

The beam ejector can be supported directly on the circular beam splitter. Here, the course of motion of the beam ejector can be controlled in parallelograms.

Suitably, the bristles are provided with at least one support element along the transport path of the tufts of bristles from the bristles to the tamping tool, the bundle of bristles being supported against the support element during transport. The slanted bristle elements are supported and erected by the support element. Therefore, the bristles are prevented from being bent.

The support members may preferably be arranged on both sides of the circular beam splitter with respect to the longitudinal direction of the bristles.

The support element can be embodied in the form of a face with a contact surface which extends over the entire length of the tuft of bristles, on which the tufts of bristles can be supported and thus prevent the bristles or individual bristles from being bent.

The beam ejector may be movable along a three-dimensional motion trajectory, wherein the distance between the circular beam splitter and the beam ejector in the longitudinal direction of the bristles is in the beam loading position of the beam ejector The beam ejector has a large release position.

The device, indicated generally at 1, for filling the tufts 2 of the tufts into the bundle receiving opening of the support body, has a means for dispensing the tufts 2 from the bristle reserve 4 and for conveying the tufts 2 The device 3 of the filling tool 5.

The device 3 for separating the tufts 2 has a circular beam splitter 6 with a beam splitting groove 7 (Fig. 5) for accommodating the tufts 2, which can The removal position positioned on the bristle reserve 4 and the splitting groove 7 are disposed between the conveying positions in the region of the stuffing tool 5.

The stuffing tool 5 has a slider housing 11 and a tool slider 12 supported therein. A not shown push tongue is guided in a linearly movable manner inside the tool slide 12 for The bristle bundle 2 is inserted into the bundle accommodating hole together with the anchor ring 13.

For the sake of simplicity, the drive elements for the various components of the device 1 are not shown.

The circular beam splitter 6 is moved along the mating abutment 8 and the splitting groove 7 containing the bristle bundle 2 is closed by the mating stop during transport of the bristle bundle 2. In the plan view according to FIGS. 1 to 3, the actual beam splitting groove 7 of the circular beam splitter 6 is covered by the flared end regions of the bristle bundle 2.

In Fig. 1, the circular beam splitter 6 has taken out a bristle bundle 2 from the bristle reserve 4 and moved in the direction of the stuffing tool 5 in accordance with the arrow Pf1. The beam ejector 9 is also moved in the direction of the stuffing tool 5 above the arc beam splitter 6 in accordance with the arrow Pf2.

According to Fig. 2, the circular beam splitter 6 has continued to move, so that the bristle bundle 2 awaits processing at the insertion area 10 of the stuffing tool 5. The beam ejector 9 is followed by the circular beam splitter 6 so that the beam ejector 9 loads the bristle bundle 2.

In Fig. 3, the tuft of bristles 2 has been completely inserted into the tamping tool 5 from the circular beam splitter 6, and the beam ejector 9, which has also continued to move, loads the bristles 2 and will open toward the insertion region 10. The bristles are pushed inward. This is well seen in the end side view according to FIG. 4 and in a partial enlarged view according to FIG. In the view according to FIGS. 4 and 5, the filling tool 5 is shown in section in the region of the tufts 2, respectively.

As can be seen in particular in FIG. 5, an additional gap 14 for the beam ejector 9 is provided in the tool slide 12 so that the beam ejector can be inserted into the tamping tool 5 or the tool slide 12 Located in the inner region and can be loaded there with the tufts 2 .

By loading the tufts 2, the tufts are pressed together such that the anchoring ring 13 holds all of the bristle elements of the tufts 2 during the filling process and the tufts 2 are completely inserted. This avoids that even for strongly expanded bristles, in particular for plant or animal natural products, individual bristles remain in the tamping tool 5 and block or damage the tamping tool.

It can also be seen well in Figure 5 that the anchoring ring 13 is placed in the circular beam splitter 6 and the beam Between the ejector 9. This ensures that the bristle bundle is carried at or near the narrowest part of the bristle bundle 2 when the anchoring ring 13 is stuffed. Instead of the anchoring ring 13, an anchoring plate can also be provided.

As best seen in Figure 6, but also in Figures 1 and 2, the beam ejector 9 has a concave end, a loading end 15 that substantially matches the outer contour of the tuft of bristles 2. The tufts 2 are thus loaded particularly reliably and pressed into the desired shape.

An additional guide element 16 is provided on the beam ejector 9 shown in FIG. The guiding element forms a guide for the anchoring ring 13 during the filling process, so that the anchoring ring 13 is guided even when inserted through the tool slide 12 for opening the opening region of the bristle bundle 2 .

In the device 1 according to FIGS. 7 and 8, a support element 17 for the tufts 2 is provided, respectively. The bristle bundle 2 can be supported on the support member 17 when transported by the circular beam splitter 6 until it faces the stuffing tool 5, thereby preventing the bristle bundle 2 from being bent or over-expanded and the bristle bundle 2 remaining substantially vertical.

In the device 1 according to Fig. 7, the support element 17 has two support arms 18 on which the tufts 2 can be supported in a point-like manner. In the device 1 according to FIG. 8 , the support element has a contact surface 19 which is arranged above and below the stuffing tool 5 .
