Definitions
- the invention relates to a roll which can be set in rotation for applying material to shoe soles or the like, which roll consists of a plurality of ring disks having a porous structure lying flat on top of one another, each ring disk being equipped with an integral skin on the ring disk broad side surfaces.
- a roller of the type in question is known, by means of which existing solution-based adhesives can be applied to flat workpieces such as shoe soles.
- the roller is formed by individual ring disks lying flat against one another and lined up on a spindle. Closed-cell foam made of polyethylene is used as the material for this.
- the washers are cut out of a layer of foam including a central cavity.
- the broad side surfaces of the ring disks are then fused to produce a skin on the broad side surfaces.
- the washers are then lined up on a spindle and clamped between the side limit washers.
- the cylindrical surface of the ring washers is then brought to the same diameter and by the action of heat fused to produce a cylindrical skin of the roller, which due to this design is not subject to shrinkage and is stable even when exposed to heat.
- a roller is known from DE-C-610 353, by means of which flowable adhesive is transferred from a container to a workpiece.
- the regulation of the order quantity takes place via a slide valve.
- the roller has an annular disc made of sponge rubber, the wide surfaces of which are flanked by rubber walls. There is therefore no skin on the wide areas.
- One broad surface is also surmounted by an adjacent thin disc, on the outer circumference of which workpiece feed teeth are provided.
- the opposite wall made of rubber is supported on a collar that is slightly larger than the diameter of the ring washer.
- the object of the invention is therefore to design a roller of the type in question in a technically simple manner so that, in addition to a short-term, high amount of abrasion from the wax bar a large storage capacity is achieved with a good application of the wax on corresponding shoe parts.
- ring disks are made of foam rubber, have a groove between the skin layers and a groove in the thickness direction and that the opposing ring disk broad surfaces with their integral skin provide a solidified zone compared to the other areas of the foam rubber ring disks form and act in the manner of a cutting edge to detach from a wax rod by means of this wax material.
- a generic roller which, on the one hand, although sponge rubber ring disks are used for its production, produces high abrasion and, on the other hand, has a high storage capacity.
- the opposing ring washer wide areas with their integral skin form a solidified zone compared to the other areas of the foam rubber ring washers and act like a cutting edge to detach from the wax rod by means of this wax material.
- the abrasion effect is supported by the fact that the cellular rubber washers between the skin layers have a groove on the surface and in the thickness direction. Accordingly, the opposing skin layers protrude beyond the adjacent area of the foam rubber washers and promote the abrasion effect of the colored wax stick.
- a large storage capacity of the roller is guaranteed due to the pores of the foam rubber washers, into which the wax liquefied by friction enters. After sufficient enrichment of the foam rubber washers with wax, which is very short-term the known designs can be done, the transfer to appropriate shoe parts is ensured in sufficient thickness. Due to the large storage capacity of the roller, larger areas can be treated with a single fill. This leads to a considerable reduction in working hours for shoe repairs.
- Another advantage is the fact that the foam rubber washers ensure a long service life. They can also be produced in a cost-saving manner, for example by punching them out of foam rubber sheets using an appropriate tool. After their wear, the foam rubber washers can be replaced easily.
- a certain interlocking engagement of two foam rubber ring disks lying on top of one another is achieved in that the outer surface of the skin is profiled on the surface. This measure precludes the spinning of a foam rubber washer from the other. Furthermore, the surface profiling leads to increased strength, which in turn has a favorable effect on abrasion.
- a plug-in mandrel 2 is used to hold the roller, which is designated as a whole by 1.
- the latter contains a central bushing 3.
- the one end thereof passes over a longitudinal slot section 4 into a curved slot 5 which crosses thereto.
- the bushing 3 or the plug-on mandrel (2) is pushed onto a rotating shaft of a shoe processing machine and brought to the latter in rotary driving motion.
- the other end of the sleeve 3 continues into a pin 6 of smaller diameter.
- a support ring 7 is slidably arranged on the bush 3.
- a radially directed grub screw 8, which acts on the circumferential surface of the bush 3, is used to fix it.
- the support ring 7 is arranged such that it overlaps the transition zone between the pin 6 and the bush 3.
- the pin 6 is the carrier of two foam rubber ring disks 9 lying flat on one another. Their outer diameter is somewhat smaller than that of the support ring 7. The foam rubber ring disks 9 are compressed to a certain extent. One abutment forms the support ring 7, while the other abutment forms one the end face of the pin 6 is supporting disk 10. The latter is caused by a central screw 11 which engages in an internal thread of the pin 6. The outer diameter of this disc 10 is slightly smaller than that of the foam rubber washers. Furthermore, the washer 10 runs along most of its length in the direction of the screw 11 in the shape of a truncated cone, so that it does not interfere with the processing of shoe parts.
- Each foam rubber washer 9 is provided in the area of its broad washer surfaces 12 with an integral skin with the foam rubber. In this way there are layers of skin that have a greater hardness than the foam rubber material in between. From Fig. 2 it can be seen that the outer skin of the skin is surface profiled. This leads to additional hardening in the skin layers. Furthermore, a certain interlocking engagement of two foam rubber washers 9 lying on top of one another is achieved, which rules out that one of the foam rubber washers rotates relative to the other.
- each foam rubber washer 9 forms a groove 13 on the outer surface side, lying in the thickness direction. In this way, projecting ring zones 14 are produced on the broad washer surfaces 12.
- each foam rubber washer 9 is equipped with a central opening 15. This is smaller in diameter than the outer diameter of the pin 6 and expands to the appropriate size when it is attached to it.
- the clamping force exerted by the support ring 7 and washer 10 on the foam rubber washers 9 is measured so large that on the one hand there is a rotation lock of the washers 9 on the pin 6 and on the other hand the foam rubber washers are not compressed so much that the absorption capacity suffers . In this way, the sufficiently firm cutting edge is always produced by the ring zones 14, which promotes the scraping off of wax from the wax rod.
- the pin 6 could also be longer to accommodate several such foam rubber washers.
- thinner foam rubber material is used for the same length, so that e.g. instead of two three ring disks are provided, which then form two cutting edges.
Abstract
Description
Die Erfindung betrifft eine in Rotation versetzbare Walze zum Auftragen von Material auf Schuhsohlen oder dergleichen, welche Walze aus aus mehreren flächig aufeinanderliegenden Ringscheiben poriger Struktur besteht, wobei jede Ringscheibe auf den Ringscheiben-Breitseitenflächen mit einer integralen Verhautung ausgestattet ist.The invention relates to a roll which can be set in rotation for applying material to shoe soles or the like, which roll consists of a plurality of ring disks having a porous structure lying flat on top of one another, each ring disk being equipped with an integral skin on the ring disk broad side surfaces.
Aus der GB-A-2 061 455 ist eine Walze der in Rede stehenden Art bekannt, mittels welcher auf Lösungsbasis bestehende Kleber auf flache Werkstücke wie Schuhsohlen aufgebracht werden können. Gebildet ist die Walze von einzelnen flächig aneinanderliegenden, auf einer Spindel aufgereihten Ringscheiben. Als Material für diese ist geschlossenzelliger, aus Polyäthylen bestehender Schaumstoff verwendet. Die Ringscheiben werden aus einer Schaumstofflage herausgeschnitten einschließlich einer zentralen Höhlung. Danach werden die Breitseitenflächen der Ringscheiben verschmolzen unter Erzeugung einer Verhautung auf den Breitseitenflächen. Anschließend werden die Ringscheiben auf einer Spindel aufgereiht und zwischen seitlichen Begrenzungsscheiben verspannt. Die zylindrische Fläche der Ringscheiben wird danach auf gleichen Durchmesser gebracht und durch Hitzeeinwirkung verschmolzen unter Erzeugung einer zylindrischen Verhautung der Walze, welche aufgrund dieser Ausbildung keiner Schrumpfung unterliegt und auch bei Wärme stabil ist.From GB-A-2 061 455 a roller of the type in question is known, by means of which existing solution-based adhesives can be applied to flat workpieces such as shoe soles. The roller is formed by individual ring disks lying flat against one another and lined up on a spindle. Closed-cell foam made of polyethylene is used as the material for this. The washers are cut out of a layer of foam including a central cavity. The broad side surfaces of the ring disks are then fused to produce a skin on the broad side surfaces. The washers are then lined up on a spindle and clamped between the side limit washers. The cylindrical surface of the ring washers is then brought to the same diameter and by the action of heat fused to produce a cylindrical skin of the roller, which due to this design is not subject to shrinkage and is stable even when exposed to heat.
Ferner ist aus der DE-C-610 353 eine Walze bekannt, mittels der fließfähiger Kleber aus einem Behälter auf ein Werkstück übertragen wird. Die Regelung der Auftragsmenge erfolgt dabei über einen Verschlußschieber. Im einzelnen besitzt die Walze eine aus Schwammgummi bestehende Ringscheibe, deren Breitflächen von Wandungen aus Gummi flankiert sind. Eine Verhautung der Breitflächen liegt also nicht vor. Die eine Breitfläche wird ferner von einer anliegenden dünnen Scheibe überragt, an deren Außenumfang Werkstück-Vorschubzähne vorgesehen sind. Die gegenüberliegende, aus Gummi bestehende Wandung findet Abstützung an einem Kragen, der etwas durchmessergrößer ist als der Ringscheiben-Durchmesser.Furthermore, a roller is known from DE-C-610 353, by means of which flowable adhesive is transferred from a container to a workpiece. The regulation of the order quantity takes place via a slide valve. In particular, the roller has an annular disc made of sponge rubber, the wide surfaces of which are flanked by rubber walls. There is therefore no skin on the wide areas. One broad surface is also surmounted by an adjacent thin disc, on the outer circumference of which workpiece feed teeth are provided. The opposite wall made of rubber is supported on a collar that is slightly larger than the diameter of the ring washer.
Des weiteren ist es auf dem Gebiet der Schuhreparatur bekannt, Gummischuhsohlen zwecks Anpassung an das Schuhleder einzufärben. Hierzu bedient man sich entsprechend farbiger Wachsstangen, von welchen mittels einer rotierenden Walze zufolge Reibung Wachs abgetragen wird. Der von der Walze aufgenommene Wachsabrieb wird dann mittels der Walze auf die Schuhsohlen, Absatzplatte etc. übertragen. Es ist bekannt, zur Herstellung der Walze, Borsten oder Textilmaterial zu verwenden. Einerseits soll das Walzenmaterial die genügende Reibung erzeugen. Andererseits ist jedoch ein entsprechendes Aufnahmevermögen erwünscht, um die Zeit für das Abtragen und Auftragen von Wachs relativ gering zu halten.Furthermore, it is known in the field of shoe repair to color rubber shoe soles for adaptation to the shoe leather. To do this, use appropriately colored wax sticks, from which wax is removed by means of a rotating roller due to friction. The wax abrasion picked up by the roller is then transferred to the shoe soles, heel plate, etc. by means of the roller. It is known to use to manufacture the roller, bristles or textile material. On the one hand, the roller material should generate sufficient friction. On the other hand, however, a corresponding absorption capacity is desirable in order to keep the time for the removal and application of wax relatively short.
Die Erfindung hat sich daher die Aufgabe gestellt, eine Walze der in Rede stehenden Art in herstellungstechnisch einfacher Weise so auszugestalten, daß neben einem kurzfristigen, mengenmäßig hohen Abrieb von der Wachsstange ein großes Speichervermögen erzielt ist bei einem guten Auftragen des Wachses auf entsprechende Schuhteile.The object of the invention is therefore to design a roller of the type in question in a technically simple manner so that, in addition to a short-term, high amount of abrasion from the wax bar a large storage capacity is achieved with a good application of the wax on corresponding shoe parts.
Gelöst ist diese Aufgabe bei einer gattungsgemäßen Walze dadurch, daß die Ringscheiben aus Moosgummi bestehen, zwischen den Verhautungsebenen eine mantelflächenseitige und in Dickenrichtung liegende Auskehlung besitzen und daß die gegeneinandertretenden Ringscheiben-Breitflächen mit ihrer integralen Verhautung eine gegenüber den übrigen Bereichen der Moosgummi-Ringscheiben verfestigte Zone bilden und in Art einer Schneide wirken, um mittels dieser Wachsmaterial von einer Wachsstange abzulösen.This object is achieved in a generic roller in that the ring disks are made of foam rubber, have a groove between the skin layers and a groove in the thickness direction and that the opposing ring disk broad surfaces with their integral skin provide a solidified zone compared to the other areas of the foam rubber ring disks form and act in the manner of a cutting edge to detach from a wax rod by means of this wax material.
Zufolge derartiger Ausgestaltung ist eine gattungsgemäße Walze angegeben, die einerseits, obwohl zu ihrer Herstellung Moosgummi-Ringscheiben verwendet werden, einen hohen Abrieb erzeugt und andererseits ein hohes Speichervermögen besitzt. Die gegeneinandertretenden Ringscheiben-Breitflächen bilden mit ihrer integralen Verhautung eine gegenüber den übrigen Bereichen der Moosgummi-Ringscheiben verfestigte Zone und wirken in Art einer Schneide, um mittels dieser Wachsmaterial von der Wachsstange abzulösen. Unterstützt wird der Abriebeffekt noch dadurch, daß die Moosgummi-Ringscheiben zwischen den Verhautungsebenen eine mantelflächenseitige und in Dickenrichtung liegende Auskehlung besitzen. Demgemäß stehen die gegeneinandertretendenden Verhautungsebenen über den angrenzenden Bereich der Moosgummi-Ringscheiben vor und begünstigen den Abriebeffekt von der eingefärbten Wachsstange. Zudem ist ein großes Speichervermögen der Walze gewährleistet bedingt durch die Poren der Moosgummi-Ringscheiben, in die das durch Reibung verflüssigte Wachs eintritt. Nach einem genügenden Anreichern der Moosgummi-Ringscheiben mit Wachs, was sehr kurzfristig gegenüber den bekannten Bauformen geschehen kann, ist das Übertragen auf entsprechende Schuhteile in ausreichender Dicke gewährleistet. Zufolge des großen Speichervermögens der Walze können bereits mit einer einzigen Füllung größere Bereiche farbbehandelt werden. Dies führt zu erheblicher Arbeitszeitverkürzung bei der Schuhreparatur. Ein weiterer Vorteil ist darin zu sehen, daß die Moosgummi-Ringscheiben eine hohe Standzeit gewährleisten. Außerdem lassen sie sich kostensparend erzeugen, indem sie beispielsweise aus Moosgummi-Platten durch ein entsprechendes Werkzeug herausgestanzt werden. Nach ihrer Abnutzung sind die Moosgummi-Ringscheiben in einfacher Weise auswechselbar.As a result of such an embodiment, a generic roller is specified which, on the one hand, although sponge rubber ring disks are used for its production, produces high abrasion and, on the other hand, has a high storage capacity. The opposing ring washer wide areas with their integral skin form a solidified zone compared to the other areas of the foam rubber ring washers and act like a cutting edge to detach from the wax rod by means of this wax material. The abrasion effect is supported by the fact that the cellular rubber washers between the skin layers have a groove on the surface and in the thickness direction. Accordingly, the opposing skin layers protrude beyond the adjacent area of the foam rubber washers and promote the abrasion effect of the colored wax stick. In addition, a large storage capacity of the roller is guaranteed due to the pores of the foam rubber washers, into which the wax liquefied by friction enters. After sufficient enrichment of the foam rubber washers with wax, which is very short-term the known designs can be done, the transfer to appropriate shoe parts is ensured in sufficient thickness. Due to the large storage capacity of the roller, larger areas can be treated with a single fill. This leads to a considerable reduction in working hours for shoe repairs. Another advantage is the fact that the foam rubber washers ensure a long service life. They can also be produced in a cost-saving manner, for example by punching them out of foam rubber sheets using an appropriate tool. After their wear, the foam rubber washers can be replaced easily.
Ein gewisser Verbundeingriff zweier aufeinanderliegender Moosgummi-Ringscheiben wird dadurch erzielt, daß die Verhautungs-Außenfläche oberflächenprofiliert ist. Diese Maßnahme schließt es aus, daß die eine Moosgummi-Ringscheibe sich zur anderen verdreht. Ferner führt die Oberflächenprofilierung zu einer erhöhten Festigkeit, die ihrerseits sich günstig auf den Abrieb auswirkt.A certain interlocking engagement of two foam rubber ring disks lying on top of one another is achieved in that the outer surface of the skin is profiled on the surface. This measure precludes the spinning of a foam rubber washer from the other. Furthermore, the surface profiling leads to increased strength, which in turn has a favorable effect on abrasion.
Sodann erweist es sich beim Arbeiten mit der Walze als vorteilhaft, daß außenseitig der letzten Ringscheibe eine etwa flächengleiche Scheibe aus starrem Material sitzt, die einen sich zu einer Umfangskante hin verjüngenden Querschnitt besitzt. Diese Maßnahme wirkt sich in einer guten Zugänglichkeit zu behandelnden Schuhteilen aus.Then, when working with the roller, it proves to be advantageous that on the outside of the last ring disk there is an approximately flat disk made of rigid material, which has a cross section tapering towards a peripheral edge. This measure results in good accessibility to the shoe parts to be treated.
Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Figuren 1 bis 3 erläutert. Es zeigt:
- Fig. 1
- eine Ansicht einer zwei Moosgummi-Ringscheiben aufweisenden Walze,
- Fig. 2
- in perspektivischer Darstellung eine einzelne Moosgummi-Ringscheibe und
- Fig. 3
- in größerem Maßstab einen Längsschnitt durch die von einem Aufsteckdorn getragene Walze.
- Fig. 1
- a view of a roller having two foam rubber washers,
- Fig. 2
- in perspective a single foam rubber washer and
- Fig. 3
- on a larger scale a longitudinal section through the roller carried by a mandrel.
Zur Aufnahme der als Ganzes mit 1 bezeichneten Walze dient ein Aufsteckdorn 2. Letzterer beinhaltet eine zentrale Büchse 3. Deren eines Ende geht über einen Längsschlitzabschnitt 4 in einen kreuzend dazu verlaufenden Kurvenschlitz 5 über. Mit diesem Ende wird die Büchse 3 bzw. der Aufsteckdorn (2) auf eine rotierende Welle einer Schuhbearbeitungsmaschine aufgesteckt und in Drehmitnahme zu dieser gebracht. Das andere Ende der Büchse 3 setzt sich in einen durchmesserkleineren Zapfen 6 fort. Auf der Büchse 3 ist verschiebbar ein Stützring 7 angeordnet. Zu seiner Festlegung dient eine radial gerichtete, die Umfangsfläche der Büchse 3 beaufschlagende Madenschraube 8. Der Stützring 7 wird so angeordnet, daß er die Übergangszone zwischen Zapfen 6 und Büchse 3 überlappt.A plug-in
Der Zapfen 6 ist beim Ausführungsbeispiel Träger zweier flächig aufeinanderliegender Moosgummi-Ringscheiben 9. Deren Außendurchmesser ist etwas kleiner als derjenige des Stützringes 7. Die Moosgummi-Ringscheiben 9 sind um ein gewisses Maß zusammengedrückt. Das eine Widerlager bildet der Stützring 7, während das andere Widerlager eine sich an der Stirnseite des Zapfens 6 abstützende Scheibe 10 ist. Letztere wird von einer zentralen Schraube 11 dursetzt, die in ein Innengewinde des Zapfens 6 eingreift. Der Außendurchmesser dieser Scheibe 10 ist etwas kleiner als derjenige der Moosgummi-Ringscheiben. Ferner verläuft die Scheibe 10 auf dem größten Teil ihrer Länge in Richtung der Schraube 11 kegelstumpfförmig zu, so daß sie bei der Bearbeitung von Schuhteilen nicht stört.In the exemplary embodiment, the
Jede Moosgummi-Ringscheibe 9 ist im Bereich ihrer Ringscheiben-Breitflächen 12 mit einer mit dem Moosgummi integraler Verhautung versehen. Auf diese Weise ergeben sich Verhautungsebenen, die gegenüber dem dazwischen liegenden Moosgummi-Material eine größere Härte besitzen. Aus Fig. 2 geht hervor, daß die Verhautungs-Außenfläche oberflächenprofiliert ist. Dies führt zu einer zusätzlichen Verhärtung in den Verhautungsebenen. Ferner wird ein gewisser Verbundeingriff zweier aufeinanderliegender Moosgummi-Ringscheiben 9 erzielt, was es ausschließt, daß die eine Moosgummi-Ringscheibe sich zur anderen verdreht.Each
Zwischen den Verhautungsebenen bzw. den Ringscheiben-Breitflächen 12 formt jede Moosgummi-Ringscheibe 9 eine mantelflächenseitige, in Dickenrichtung liegende Auskehlung 13. Auf diese Weise werden vorstehende Ringzonen 14 an den Ringscheiben-Breitflächen 12 erzeugt.Between the skin layers or the washer
Um die Moosgummi-Ringscheiben 9 dem Zapfen 6 zuordnen zu können, ist jede Moosgummi-Ringscheibe 9 mit einer zentralen Öffnung 15 ausgestattet. Diese ist durchmesserkleiner als der Außendurchmesser des Zapfens 6 und weitet sich bei dem Aufstecken auf diesen auf das entsprechende Maß.In order to be able to assign the
Nach dem Aufsetzen der Moosgummi-Ringscheiben 9 auf den Zapfen 6 und dem Einklemmen zwischen dem Stützring 7 und der Scheibe 10 ergibt sich, im Querschnitt gesehen, ein wellenförmig verlaufender Mantelbereich. Den Wellenberg W bilden die Endzonen 14 der gegeneinander tretenden Ringscheiben-Breitflächen 12. Hierdurch wird eine mittlere, gegenüber dem Moosgummi-Material härtere Zone geschaffen, so daß beim Andrücken einer eingefärbten Wachsstange zufolge vergrößerter Reibung Wachs von dieser abgetragen wird, welches seinerseits von dem Moosgummi aufgenommen wird. Letzteres zeichnet sich durch ein großes Speichervermögen aus, so daß anschließend zu behandelnde Schuhteile, wie z.B. helle Schuhsohlen, gut eingefärbt werden können.After placing the
Die von dem Stützring 7 und Scheibe 10 auf die Moosgummi-Ringscheiben 9 ausgeübte Spannkraft ist so groß gemessen, daß einerseits eine Drehsicherung der Ringscheiben 9 auf dem Zapfen 6 vorliegt und andererseits die Moosgummi-Ringscheiben nicht so sehr verdichtet werden, daß darunter das Aufnahmevermögen leidet. Auf diese Weise wird stets die genügend feste Schneide von den Ringzonen 14 erzeugt, die das Abschaben von Wachs von der Wachsstange begünstigt.The clamping force exerted by the
Anstatt wie dargestellt ist, könnte der Zapfen 6 auch länger ausgebildet sein, um mehrere solcher Moosgummi-Ringscheiben aufnehmen. Eine weitere Variation besteht darin, daß bei gleicher Länge dünneres Moosgummimaterial verwendet wird, so daß dann z.B. statt zwei drei Ringscheiben vorgesehen sind, die dann zwei Abtragsschneiden bilden. Die besondere, sich im Querschnitt zum Umfang hin zu einer Kante verjüngende Form der Scheibe 10 gewährleistet, daß selbst bei optimaler Wachsanreicherung dieses nicht auf das Oberleder eines Schuhes gelangt.Instead of as shown, the
