Description

Small carrying plates and brushes, especially toothbrushes with small carrying plates

The invention relates to a method for manufacturing a bristles field of a brush, especially a toothbrush. The bristles are taken out from a material box with a bristles stock, and are assembled into a bristle bundle. The guide bristles pass through a bundle of accommodating devices and a delivery device containing a hollow tube connected thereto, and then are placed into the holes of a bundle of holding plates.

The invention relates to a small carrier plate, which has a plurality of holes through which the small carrier plate passes. A bristle bundle composed of bristle wires can be inserted into the hole, and can be fixed on the small carrier plate without a holder.

The invention also relates to a brush, especially a toothbrush, which has a handle and a brush head, and the brush head has a small bearing plate holder and a small bearing plate fixed therein with a bristle bundle.

The aforementioned method can be performed on a device for making brushes, especially toothbrushes, in a bristle field. The device has a material box containing a stock of bristle filaments, and at least one take-out device for taking out individual bristle bundles from the bristle stock. , And has a conveying device, the conveying device has a hollow catheter, bristles The beam can be conveyed by a gas or air flow into the holes of a beam holding plate via the conveying device.

The aforementioned methods, small carrier plates, brushes, and devices for making bristle fields are known in different forms.

In a method and a device for manufacturing a bristle field known in the prior art, when a bristle bundle composed of individual bristle filaments is fed through a conveying device with a gas flow or an air flow, it is possible to feed the bristle filaments to the device. Problems occurred at the section or station behind the conveyor.

It can happen, for example, that individual bristle filaments or even entire bristle bundles are trapped in the conveyor and cannot reach their destination. Especially when the bristle filaments are extremely thin, it is particularly difficult to reliably feed the bristle filaments via a conveying device.

Also in the conventionally known small carrier plate and the brush provided with such a small carrier plate, the bristle bundles are fed into the small carrier plate according to a method and a device described above, in a fixtureless manner. This can cause problems in particular.

The conventional small carrier plate and a toothbrush equipped with such a small carrier plate require, for example, that the bristle wires assembled into a bristle bundle are sent to the holes of the small carrier plate, and the ends of the individual bristle bundles positioned in the holes are covered with a material. Overshoot, 俾 will fix the bundle of bristles in the hole. In addition, it is conventionally known that the bristle filaments are assembled in a bunching manner, and have been melted to each other before being transported to a small carrier plate that needs to be provided with a bristle bundle.

Once the ends of the melted bristle bundles reach the small carrier plate, The ends that enter into the holes of the small carrier plate and melt each other are coated and ejected, so that the bristle bundles are fixed on the bundle holding plate.

The object of the present invention is therefore to propose a small carrying plate and a brush as defined above, in particular a toothbrush, which allows the bristle field to be manufactured in an efficient and simple manner, and thus allows an efficient and simple brush, especially a toothbrush , Made.

In order to better understand the present invention, the technical field of manufacturing bristle fields and brushes will first be described in detail through a particularly advantageous embodiment of the method of manufacturing a bristle field that best represents the quality of the present invention.

In the method defined above, in order to make the bristle field more efficient and simpler, and therefore more efficient and simpler to make brushes, especially toothbrushes, specially set, the bristle filaments constituting the bristle bundle are conveyed to the bundle by the conveying device. Electrostatic discharge while holding the board.

Especially on the feeding of the so-called chemically sharpened bristle filaments, because of its characteristics of having a particularly thin filament thickness, the conveying device is always blocked in the conventional methods of the prior art. The reason was found to be the bristles that constitute the tufts Static electricity charging. Due to the friction effect acting on the bristles of the bristle bundle during the conveyance of the conveying device, whether it is through a gas flow or an air flow, or a material through a hollow duct through which the bristle bundle passes, the bristle bundle and the The bristle wire may be electrostatically charged, causing it to adhere to the components of the conveying device, especially to the hollow tube of the conveying device, and it cannot be reliably charged. Guided through the conveyor. In addition, there is even danger that the bristle filaments are strongly electrostatically charged during transportation through the conveying device, so that they block the conveying device, and it is best to reduce the circulation of the bristle filaments to the beam holding plate.

This disadvantage can be avoided by the electrostatic discharge of the bristle wire during transportation. Finally, a method can be obtained, which can particularly effectively feed particularly thin bristle filaments, that is, such chemical sharpeners, to the beam holding plate by gas flow or air flow, and further processing.

In order to reliably discharge the bristle bundles, it is particularly advantageous that the bristle filaments constituting the bristle bundles are electrostatically discharged when they are conveyed through the bundle receiving device of the conveying device and / or when they are conveyed to the bundle holding plate through the hollow tube of the conveying device.

In particular, the electrostatic discharge during the transportation of the bristle filaments through the bundle containing device can prevent the electrostatic charging of the bristle filaments from the beginning of its transportation through the conveyance device.

An electrostatic discharge when an optional or additional bristle wire is conveyed to the beam holding plate through the hollow tube of the conveying device can prevent the bristle wire from rubbing against the inside of the hollow tube to electrostatically charge and block the hollow tube.

A particularly simple but equally reliable electrostatic discharge of the bristle filaments consists in that the bristle filaments constituting the bristle bundle are transported by a conveying device, in particular when they are conveyed to the bundle holding plate via a bundle receiving device and / or via a hollow tube, for electrostatic discharge Ground.

To this end, the bristle bundles can be conveyed to the bundle holding plate when they are conveyed via the conveying device, in particular via the bundle receiving device and / or via a hollow tube. At least, for electrostatic discharge, it is guided at least through an electrical contact or a ground contact provided on the conveying device and comes into contact with it. It should be noted that, for example, the at least one electrical contact or the ground contact may be provided in the beam receiving device and / or also in the hollow tube.

The bristle filaments constituting the bristle bundle in this way can achieve a particularly simple but reliable electrostatic discharge. It should be pointed out here that the electrostatic discharge of the bristle filaments constituting the bristle bundle during its transport through the conveying device not only allows the electrostatic charge accumulated on the bristle filaments to be released, but also allows to avoid the electrostatic charging of the bristle filaments. This electrostatic charging is particularly The friction of the bristle filaments constituting the bristle bundle is generated when being conveyed by the conveying device.

In one embodiment of the method, it may be provided that the tufts of bristles are directly inserted into the holes of a small carrier plate by the bundle holding plate. In a particularly advantageous embodiment of the method, it can be provided that the bristle bundles are sent from a tapered funnel channel of a funnel plate to a hole of a small carrier plate, in particular by means of a compression rod. This approach can be very meaningful, because if the bristle bundle compression density required for the implantation of a high-quality small carrier plate by a gas flow or air flow alone is extremely complicated. In practice, the tuft of bristles to be fed is first forced through the funnel channel of the funnel plate, and the desired density can be achieved in a relatively simple manner and method, especially when a compression rod is used.

In order to be able to fix the bristle bundle to the small carrier plate in a fixture-free manner, it can be arranged that the material protruding from the rear side of the small carrier plate away from the bristle bundle and protruding toward the rear side is heated and melted at a welding station, and melted Material The raised melt is pressed into a fixed surface of the bristle bundle, so that the melt flows in, especially from the rear of the small carrier plate, between the ends of the bristle bundle, and / or between the ends of the filaments flowing into the bristle bundle. Hardenable, connecting bristle bundles to small carrier plates. Therefore, the bristle bundles can be fixed on the small bearing plate by means of shape fitting and / or force fitting. This is because the melt is pressed to the fixing surface of the bristle bundles, and can be approximately fitted with the ends of the bristle bundles.

A particularly simple method can be produced in this way, without the need for a holder, for fixing the bristle bundles in a small carrier plate.

Advantageously, the material protrusion on the small carrier plate is heated and melted by at least one melting rod, and is pressed to a fixed surface of the bristle bundle to fix the bristle bundle on the small carrier plate.

The advantages of the method can be particularly exerted when a bristle bundle composed of chemically sharpened bristle filaments is fed to the bundle holding plate. This bristle wire, also known as chemical tapered filament-CTF's, is characterized by a particularly slender trending end of the wire that is free in use. This feature has so far caused this kind of bristle wire to be conveyed by a conveying device through a gas or air flow. Feeding is very difficult due to the electrostatic charging of the particularly thin bristle filaments in this case, which is uneconomical.

In another embodiment of the method, it can be provided that the bristle filaments are fed to a transfer station in a wire tray which is wrapped by a particularly elastic and / or air-tight sheath. Then the reel fed to the transfer station can be sucked by at least one suction claw configured to the transfer station, and the at least one suction claw contacts and sucks the free upper side of the silk disk with a suction plate, and through this, it is particularly elastic And / or airtight harness sleeves The longitudinal axis of the bristle filaments is sucked inward in the longitudinal middle axis direction which is at right angles to the upper side of a filament disc, and the bristle filaments of the filament discs can be stably tightened through this. After suctioning, the wire reel can be delivered to a debarking station located behind the transfer station by at least one suction claw. The sleeve of the wire reel can be opened and removed at the de-sleeve station. After that, the bristle filaments released by the sleeve can be fed into one or the aforementioned material box, preferably by automatic feeding.

It should be pointed out here that the reel of chemically sharpened bristle filaments has a flexible and / or air-tight sleeve, as previously described in DE 10 2013 003 249, which relates to a method of manufacturing such a reel. .

The operation mode of the aforementioned de-sleeve station is described, for example, in German patent application DE 10 2014 109 320.

An advantageous method may be that the silk disc is provided with a spin finish, which has antistatic additives of CFT's, which can additionally reduce the tendency of the electrostatic charging of the bristle filaments during transportation.

In another advantageous embodiment of the foregoing method, it may be further provided that the wire reel is fed to the transfer station, in particular, at least one of the feeding surfaces of the feeding station, which is preferably designed as a conveyor belt, is fed at least to the transfer station. One suction claw.

This approach can further improve the efficiency and automation of the aforementioned method.

The method can be further simplified for a person who is familiar with the method. The method is that the wire reel is on the feeding station, especially on at least one bearing surface which is preferably designed as a conveyor belt, individually and / or on its delivery. Inside the container It is better to keep it manually when needed, especially to take it out directly from the delivery container and move it to at least one bearing surface, but especially to the direction of conveyance to the at least one bearing surface. Therefore, a person familiar with the practice of the present invention can prepare a certain number of delivery containers with wire reels, and place them on the bearing surface of the feeding station designed as a conveyor belt, when needed, that is, when the silk on the bearing surface of the feeding station has been When the disc is exhausted by subsequent stations of the device, it can be replenished. Depending on the number of silk reels on the bearing surface and according to the processing time, that is, the time required to process a silk reel at each subsequent station, the person familiar with the method has enough time to perform other tasks and only takes care of the feed within a certain time interval Station, add more silk reels, so that the rest of the automated manufacturing process can not be affected and continue to operate.

The object of the present invention is that the small carrier plate defined in the foregoing is characterized by the first item in the scope of patent application, and in particular, the small carrier plate has a plurality of material protrusions on its back side away from the tuft of bristles placed in the hole. And it was achieved that the material protrusion can be melted and can be pressed into a bunch of fixing surfaces to fix the bristle bundle on a small carrier plate.

One such small carrier plate allows the bristle bundles to be fixed on the small carrier plate in a fixtureless manner, without the need to weld the bristle bundles to be fixed in the small carrier plate to each other before feeding to the small carrier plate. Therefore, the small carrier plate of the present invention supports the implementation of the aforementioned method in a particularly advantageous manner.

In one embodiment of the small carrier plate, it can be provided that the tufts of bristles that can be inserted into the holes are formed by sharpened bristle filaments, especially by chemically sharpened bristle filaments. This bristles, at least after they are fixed on the small carrier plate The bundle can constitute a bristle field of sharpened bristle filaments, especially a bristle field of chemically sharpened bristle filaments.

In another embodiment of the small carrier plate, it may be provided that a part of the bristle bundles that can be inserted into or have been inserted into the hole is composed of sharpened bristle filaments, especially chemically sharpened bristle filaments. The other part of the tuft of bristles that has been or has been placed in the hole is made up of traditional bristles. The so-called traditional bristle filaments refer to bristle filaments which have at least a large part of their length or have the same or the same cross-section over their entire length. A bristle bundle composed of sharpened bristle filaments and a bristle bundle composed of traditional bristle filaments constitute a hybrid bristle field at least after they are fixed on a small carrier plate.

The bristle filaments may be composed of polyamide and / or polyester. However, the preference is that traditional bristle filaments, especially those with the same cross section, are composed of polyamide, and sharpened bristle filaments, especially chemically sharpened bristle filaments, are composed of polyester, especially polyphenylene terephthalate. Butyl formate (abbreviation PBT).

A characteristic of polyester is that it only contains a small amount or even no moisture at all. In particular, brine may be used on the chemical sharpening of the bristles, which is then removed in a cleaning procedure. It may be necessary to dry the cleaned bristles to facilitate subsequent processing. The use of polyester as the material for the chemically sharpened bristle filaments, and the fact that polyester contains only a small amount or no moisture at all, helps the drying process of the bristle filaments to be cleaned and accelerates the drying. In this way, the drying process can be carried out on a scale that makes sense to an industry.

The advantage is that the bristle bundles are melted after the material is raised and melted. After the solution material is pressed into the bundle fixing surface, it is connected with the small carrier plate by means of shape fitting and / or force fitting. In this way, a reliable fixing of the tufts of bristles in or on the small carrier plate can be obtained, which can bear the pulling force to which it is subjected.

Advantageously, the material protrusion is designed as a nodule, and the material protrusion may protrude laterally from the rear side of the small carrier plate. Transverse means that in this connection, the material protrusions basically continue into the bristle bundles of the small carrier plate, which can protrude from the rear side of the small carrier plate. Advantageously, the longitudinal center axis of one of the material protrusions forms a right angle to the rear side of the small carrier plate.

In addition, it can be provided that the material protrusions are arranged in particular evenly around the holes of the small carrier plate or between the holes. This method is beneficial to the uniform distribution of the melt, especially after the melt is pressed into the fixed surface of the bundle, it is evenly distributed on the rear side of the small carrier plate and between the ends of the bristle bundles, especially the individual bristle filaments of the bristle bundles. And thus help to securely fix the bristle bundles in the small carrier plate.

In order to be able to manufacture bristle fields with different bristle bundle cross sections, it is advantageous that the holes in the small carrier plate have different cross sections. The hole may thus have, for example, a circular arc shape and / or an olive shape and / or a circular shape and / or a polygonal cross section. The combination of holes with different cross sections is inherently feasible. In addition, holes can be designed as long holes.

The small carrier plate of the present invention can be manufactured in a particularly simple manner, when the material protrusion is integrally connected to the small carrier plate, and / or when the material protrusion is composed of the same material as the small carrier plate, especially a meltable plastic Material composition, preferably thermoplastic plastic material. The material constituting the raised material may have a lower or higher melting than the material constituting the bristle filaments and / or the bristle bundles. point. A typical material constituting the small bearing plate and / or the material protruding on the rear side of the small bearing plate is a plastic material polypropylene. A typical material constituting the bristle bundles and filaments is polybutylene terephthalate (abbreviated as PBT).

Advantageously, the material projections taper towards their free ends, in particular tapered. When the material protrusion has a tapered shape, the material protrusion is significantly easier to melt when the melting rod is pressed.

It is particularly advantageous that the rear side of the small carrier plate away from the bristle bundle has an infinitely long and closed restriction ring, especially a right-angled protruding ring from the rear side of the small carrier plate. This confinement ring can surround the hole and the material protrusion, and contains the rear side of the small carrier plate. The restriction ring on the rear side of the small carrier plate can prevent the molten material protruding from the side from overflowing under the pressure of the welding rod, and when the melt is pressed to the fixed surface of the small carrier plate, it can also help the melting. Reliable guidance of raised material.

In order to prevent the molten material from being squeezed out laterally, a particularly reliable method is that the restriction ring of the small bearing plate has at least one-half the height of the material protrusion provided on the rear side of the small bearing plate. In a particularly advantageous embodiment of the small carrier plate, this restriction ring may be higher than the material protrusion on the rear side of the small carrier plate, especially twice as high. Therefore, when the molten material is pressed, especially by a melting rod, to the fixed plane of the bundle of the small carrier plate, the convex material of the molten material can be prevented from being pushed out laterally and reliably.

In a further advantageous embodiment of the small carrier plate according to the invention, it can be provided that the small carrier plate is away from the rear side of its bristle bundle, at least after the bristle bundle is covered. After being placed into the hole and / or after the material protrusions are melted and compressed, a cover is provided, especially a cover that can be injection-molded or molded in an in-mold method. This cover shields the bulging of the molten material located on the rear side of the small carrier plate together with the ends of the tufts of bristles. In addition, the cover helps the bristles to be properly fixed in the use position, and provides a flat surface on the rear side of the small carrier plate, which facilitates the small carrier plate to be fixed on a brush, especially on a toothbrush.

The object of the present invention is achieved on the brushes of the aforementioned definition by the features of the 13th scope of the patent application, especially through the small carrier plate is a small carrier plate of the present invention, that is, according to patent claims 1 to 12 Any one of them is reached.

It may be particularly advantageous if the small carrier plate is clamped in a small carrier plate receptacle. It may additionally or additionally be that the small carrier plate is glued into the small carrier plate holder and / or welded, in particular by means of an ultrasonic welding method. In this way, the small carrier plate can be reliably fixed to the brush.

Another method for connecting the small carrier plate to the brush is that the small carrier plate is fixed to the brush by an in-mold method, especially to the small carrier plate holder of the brush.

The small carrier plate of the present invention allows processing, especially using the aforementioned method, on a device for manufacturing brushes, especially toothbrushes, and bristles fields, as previously defined. This device has an independent invention quality and has a special feature that the conveying device is electrically grounded to release the electrostatic charge attached to the bristle filaments and / or bristle bundles that need to be conveyed.

With the help of at least one extraction device, individual tufts of bristles can be taken out of the bristle stock with bristle filaments. In order to be able to feed the tufts of bristles to the conveying device, it is advantageous that the conveying device has at least one holding device, and the side of the hollow duct material box The end is attached to it. Advantageously, the at least one bundle receiving device and / or the hollow tube can be electrically grounded, so that the electrostatic charges are taken away by the bristle filaments and the bristle bundles to be conveyed, and the bristle filaments and / or bristle bundles to be conveyed are avoided. It is electrostatically charged when it is transported by the transport device.

In order to effectively dissipate the electrostatic charge, it may be advantageous that one of the at least one bundle receiving device and / or at least one hollow tube has at least one electrical ground contact or ground contact, which is connected to the bristle bundle and / or is contained in The bristle filaments in the bristle bundles are intermittently contacted at least in time when conveyed through the bundle receiving device and / or through at least one hollow catheter. In particular, the beam receiving device and / or at least one of the hollow conduits and / or the contact or ground contact is connected to the ground via at least one electrical lead, particularly via an electrical grounding base of the device.

In one embodiment of the device, at least one hollow conduit can be provided as an electrical grounding point or a grounding contact, and has an electrical grounding inner cover surface. The material is a conductive material, especially a metal, and steel, stainless steel. Or copper, which is in contact with the bristle bundles and / or the bristle filaments contained therein.

Advantageously, the hollow conduit of the device is constructed as a tube from an elastic material and / or as a Bowden sleeve (Bowdenzugmantel) and / or also as a connecting section of the tube from a conductive material, in particular from metal, steel, A rust steel or copper composition is preferred. However, the use of hollow tubes made of Bourdon sleeves is preferred because of their special cost and good suitability for conducting electrostatic charges away.

A particularly efficient way to feed bundles of bristles to a bundle holding plate on standby is that the number of hollow ducts in the conveying device corresponds to the number of holes in the bundle holding plate.

It is advantageous, especially when considering the implementation of the aforementioned method, that the beam holding plate is designed as a transport plate, which can be transferred to a subsequent processing equipment, in particular to a welding station. In another embodiment of the present invention, the bundle holding plate may have at least one small carrier plate holder for the use of a small carrier plate at a side remote from the conveying device when in the accommodation position. Any one of claims 1 to 12.

It must be pointed out that the bundle holding plate can also be a brush part or an injection-type insert, which can be processed at subsequent stations of the device after the bristle bundle is loaded.

In another embodiment of the device, it may be particularly important to provide that the hollow conduits of the delivery device each lead to a guide channel of a guide element. This guide element may also be called a feed block. Each of the guide channels of the guide element or the feeding block is designed as a through hole. It should be noted that the distance between the lead-out sides of the guide channel may be smaller than the distance between the lead-in sides. It may be particularly advantageous that the outlet of the feed channel corresponds to a combination of holes for the bristle bundles to be inserted into the bundle holding plate and / or is arranged to access these holes. In this way, the insertion of the bundle holding plate after the bristle bundles are fed by the conveying device can be carried out particularly efficiently.

The feeding channel of the guide element or the guide block functions as the same hopper, and the bundles of bristles to be fed are fed into the bundle holding plate in a manner of being close to each other during their transportation.

In order to be able to place the tufts of bristles into the holes of the small carrier plate held on the device at the required compression density, it is advantageous that the device has a space between the tuft holding plate and a small carrier plate on which tufts of bristles need to be inserted. The funnel plate is preferably a small carrier plate according to any one of patent claims 1 to 12, and the funnel plate has a funnel channel that is tapered especially in the direction of the bristle bundle conveying direction. The bristle bundles are arranged and combined in the bundle holding plate and face the small bearing plate to be inserted. After passing through the funnel channel, the bristle bundles can be introduced into the bundle holding plate and held on the funnel plate to be held by the small bearing plate held on the funnel plate. It is better in the device, in the hole of the small bearing plate. It is advantageous that the inlets of the funnel channels correspond in number and combination to the outlets of the holes in the beam holding plate, and the outlets of the funnel channels correspond in number and combination to the holes of the small carrier plate. In addition, it is advantageous that the outlet of the funnel channel passes into the hole of a small carrier plate held on the funnel plate, so that the bristle bundle is introduced into the small carrier plate to be inserted as easily as possible from the bundle holding plate through the funnel plate.

In order for the bristle bundles fed by the conveying device of the bundle holding plate to reliably enter the holes of a small carrier plate held on the funnel plate through the funnel plate at the desired compression density, the device may have a compression station, which The station has at least one compression rod which has the same number and combination as the holes of the beam holding plate and / or the funnel channels of the funnel plate and / or the holes of the small load bearing plate. Of compressed fingers. With the help of the compression fingers, especially the tufts of bristles which are placed in the funnel plate and / or the bundle holding plate can be placed and held on the device, especially the funnel plate and / or the bundle holding plate. In the hole of the carrier plate.

In this way, the bristle filaments assembled into tufts of bristles can be fed at a low compression density necessary for the conveying device to convey by a gas or air stream, and then mechanically placed into the small holding means by means of a compression rod. The holes in the carrier plate can be compressed to the required higher compression density at the same time. Especially at higher compression densities, the mechanical compression of the bristle bundles can also contribute to the aforementioned funnel channel of the funnel plate, representing a particularly simple method and method of compressing and placing the bristle bundles on standby small carrier plates. .

In particular, it may be advantageous to carry out the aforementioned method in that the device has a conveying jaw and a welding station. The conveying jaw may be preferably designed as a turntable, which has at least one conveying receptacle for a funnel plate and / or a bundle holding plate loaded with tufts of bristles and / or at least one small carrier plate. It must be pointed out that the bundle holding plate, which can additionally assume the function of the conveying plate, can be conveyed to one or only welding station by loading the bristle bundle and / or at least one small carrier plate on the bundle holding plate by the conveying clamp. The welding station can be connected to at least one small supporting plate in a form-fitting and / or force-fitting manner.

In addition, it is feasible that the at least one hopper plate can also be conveyed between the stations of the device by a conveying jaw.

Advantageously, the welding station has at least one welding rod for connecting the bristle bundle with the at least one small carrier plate, so that the welding rod bristle bundle can be connected with at least one small Carrier board connection. The small carrier plate to be processed is a small carrier plate according to any one of patent claims 1 to 12, and the at least one welding rod can be used for melting the material protrusion of the small bearing plate and the material protrusion for compressing the melting. Lift into the bundle fixing surface of each small bearing plate. In the meantime, the at least one welding rod contacts a rear side of one of the small carrier plates at the welding position.

In one embodiment of the present invention, the at least one welding rod can be heated to a temperature of about 500 ° C., and the bristle bundles are welded to the small bearing plates.

It should be pointed out again here that the use of a small carrier plate according to any of the claims 1-12 of the invention, together with the device described above, can greatly simplify the production of bristle bundles, especially if the foregoing description is also used Method.

If the bristled filaments used are chemically sharpened bristles, so-called chemical tapered filaments CTF's, the advantages of this device for making tufts of bristles can be particularly huge, because these particularly fine bristles are When the gas stream or air stream is conveyed through the conveying device, it may be significantly affected by electrostatic charging, so that the feeding of such chemically sharpened bristle filaments has so far been completed with a disproportionately large cost.

Advantageously, the device has a removal sleeve station placed in front of the material box for removing the bristle filaments which are bundled in the wire tray by a bundle. The sleeve removal station may have at least one cutting device having at least one cutting tool for cutting the sleeve of the wire reel, and at least one clamping mechanism for removing the opened sleeve. In addition, it is advantageous that the debarking station is connected to the material box behind it. The bristles of the de-sleeve are fed into the material box. For this purpose, in one embodiment of the device, the sleeve removal station may have a clamping jaw and / or at least one slider for feeding the bristle bundle after the sleeve removal to the material box, preferably in an automated manner.

In this way, an automatic feed from the wire reel to the de-jacketing station is achieved.

In the meantime, for example, one of the aforementioned transfer stations, such as at least one of the aforementioned, the suction claw has a suction plate, and the suction plate preferably has a densely-bristled mesh structure, especially a Tressen ) Net tissue, the suction plate can hold at least one wire tray, and it can be sucked away from the bearing surface through the wire tray and without the front end side of the sleeve.

It can be easier to suck at least one suction claw of the transfer station and then handle and handle at least one reel. The method is to keep the bundle of the reels in a concentrated way. The bristle wire gathered in the wire tray is tightened radially at the longitudinal side of the use position, so that the upper side of the front end of the wire tray is free of the sheath.

Advantageously, the sleeve is designed as an infinitely long belt, that is, as a tape roll, as an overlapping tube segment of disc-shaped bristle filaments, or as an overlapping sleeve. An advantageous method is that the height of the sleeve corresponds to the length of the bristle filaments of the wire reel.

The use of a suction claw, such as the one mentioned above, to grip the wire reel being tightened by the cover can be easier, in that the wire reel's cover is made of an elastic and / or air-impermeable material. The material suitable for the harness must be elastic and impermeable, such as polyethylene, preferably PE-LD.

In addition, the device may have one and one, such as the aforementioned, a feeding station connected to a transfer station, which contains at least one, in particular a bearing surface designed as a conveyor belt. The wire reel can be fed to the transfer station and / or to at least one suction claw of the transfer station on the at least one bearing surface. In order to reliably pick up the individual reels from the bearing surface, for example with the aid of suction claws, it is advantageous to maintain the distance between the reels on at least one of the loading surfaces of a feeding station which is preferably designed as a conveyor belt. In order to maintain the distance between the reel on the bearing surface, the bearing surface may have a plurality of accommodating pits, especially in the conveying direction, each of which is placed in the individual reel, and the reel can continue to be conveyed in the reel .

If the feeding station has at least one of its longitudinal sides, especially one of the longitudinal sides of at least one bearing surface, it has at least one fixed storage surface adjacent to the at least one bearing surface for individual preparation of the reel in advance. And / or at least For the use of the delivery container of the divided loading reel, the bearing surface, especially the receiving recesses of the bearing surface designed to keep a distance from each other, can load the reel very quickly and efficiently when needed. For this purpose, the reel can be placed on the bearing surface, or taken out from the adjacent storage surface, or directly from the prepared delivery container. The delivery container can also be kept on the adjacent storage surface, as long as it is on the bearing surface. There is space on the reel for feeding at least one suction claw to the transfer station and / or to the transfer station.
