Definitions
- the invention relates to a recording medium for holding individual workpieces for their processing and transport according to the preamble of claim 1.
- a recording medium is for example from the patent document EP-A-1 413 242 known.
- a carrier plate made of stainless steel in which a plurality of holes are incorporated with one or more radially extending grooves.
- a round Anformung is provided at the bottom of the receiving carrier, on the opposite side, on which a web spaced and parallel to the bottom.
- the Anformung can be screwed into the bore of the support plate in the manner of a bayonet catch or undercut.
- one of the receiving carriers can be fixed in each bore, so that a large number of receiving carriers can be arranged on a common carrier plate.
- the carrier plate can then be supplied together with the receiving carriers and the workpieces inserted therein a cleaning station or a coating center.
- the cleaning agent or the particles forming the coating pass through the intermediate spaces which are present between two adjacent holding fingers and the open end face opposite the bottom, into the interior and thus in the direction of the workpiece.
- the plastic material of the holding fingers and the bottom is resistant to the often aggressive cleaning and coating agents and therefore has a long service life.
- a receiving body which consists of a plurality of retaining fingers, between which circumferential support ribs are formed.
- the receiving body disclosed by this prior art has no bottom, so that this is disadvantageously unsuitable to be snapped onto support plates, because it lacks the necessary holding elements to lock the receiving body to the support plate can.
- the holding fingers lose their stability and leach after a certain period of use.
- the cleaning and coating agents acting on the workpiece often exert a considerable pressure on the holding fingers, which causes them to be bent out of their initial position.
- the individual recording media are to be encompassed. This is done for example by means of robots which exert a corresponding force on the retaining fingers, so that the dimensional stability of the retaining fingers is also reduced by these processing and treatment forces.
- the holding fingers no longer assume their original position, then the workpiece wobbles inside the receiving carrier and is not held reliably by this. This can lead to damage or improper coating and cleaning of the workpiece.
- a recording medium is to be made available, which can be arranged as close as possible to other recording media on a support plate, so that no unnecessary space between the adjacent recording media. Furthermore, it is an object of the invention to develop a recording medium of the type mentioned in such a way that the space enclosed by the holding fingers and the bottom space for receiving the workpiece on the outer contour is adjustable in order to adjust the volume of the space optimally to the volume of the workpiece can and to facilitate the insertion of the workpiece.
- the recording medium is thus configured in the form of a cage.
- the support ribs can be arranged in a common or in mutually different height levels. It is particularly advantageous if a plurality of support ribs are arranged at a common height level concentrically about the longitudinal axis of the receiving carrier and if several such levels of support ribs spaced from each other on the retaining fingers are mounted to stabilize them at several positions in their predetermined position.
- the receiving media can be positioned adjacent to other receiving media adjacent to one another on a carrier plate. Thus, no space is created between the adjacent recording media and the positioning surface provided by the carrier plate is optimally utilized.
- a rail-shaped Anformung is provided in the corner regions of the receiving carrier, which reduces the volume of the retaining fingers and the ground formed space, so that the volume of the space is optimally adapted to the workpiece inserted into this.
- the recording media can be engaged in a recess which is incorporated in the support plate in the manner of an undercut, because the locking device consists of two or more holding pillars, between each an air gap is present.
- the air gap in this case has a V-shaped or U-shaped inner contour through which the retaining fingers are pushed radially, ie in the direction of the longitudinal axis of the receiving carrier to adjust the outer periphery of the retaining pillars to the inner diameter of the recess of the support plate, so that the retaining pillars the recess in a simple way fürdrückbar and are reliably held in the recess after Verrastungsvorgang.
- the retaining pillars have a thickening from outside to inside outer contour, so that upon insertion of the receiving pillars in the recess of the support plate, the retaining pillars are compressed in the direction of the center of the bottom and as soon as the retaining pillars leave the recess, spring back outwards a reliable attachment of the recording medium is secured to the support plate. Accordingly, the retaining pillars can be inserted vertically from above into the recess of the carrier plate, so that the bottom can have a rectangular outer contour, since twisting of the receiving carrier is no longer necessary. Consequently, the outer surfaces of the retaining fingers come into contact with the outer surfaces of retaining fingers of the adjacent receiving carrier, so that there is no gap between them.
- FIG. 1 is a support plate 9 for holding rectangular recording media 1 and round recording media 1 'shown by the cleaned or coated to be cleaned workpieces 5 are isolated.
- the recording media 1 and 1 ' consist of a bottom 2 and of four perpendicular and parallel to each other holding fingers 3.
- the longitudinal axis of the respective recording medium 1 and 1' is marked by the reference numeral 3 'and corresponds substantially perpendicular to the Floor 2 protruding normals 6.
- the bottom 2 and the holding fingers 3 define a space 4, in which the workpiece 5 is inserted. Since between two adjacent retaining fingers 3, a gap 24 is provided and the bottom 2 opposite end face of the receiving carrier 1 is designed to be open, cleaning or coating agent can penetrate in the direction of the workpiece 5 through these openings.
- the workpiece 5 facing the top of the bottom 2 is provided with the reference numeral 7 and the opposite bottom of the bottom 2 by the reference numeral 8.
- a locking device 14 is mounted on the underside 8 of the bottom 2, which is explained in more detail below.
- a support rib 11 is provided between two adjacent retaining fingers 3, which run concentrically around and perpendicular to the longitudinal axis 3 'of the receiving carrier 1. It is particularly advantageous if the support ribs 11 are arranged in the region of the externally accessible openings between the retaining fingers 3, ie in the region of the free ends of the retaining fingers 3, and if the support ribs 11 extend at a common height level, because this ensures that the free ends of the retaining fingers 3 are mutually supported. In order to further increase the stability of the retaining fingers 3, further support ribs 11 extending parallel to one another are provided between two adjacent retaining fingers 3. Between the support ribs 11 and the retaining fingers 3, the intermediate spaces 24 are present through which a sufficient amount of cleaning and / or coating agent enters the space 4 in the direction of the workpieces 5.
- a recess 10 is incorporated in this, in which two radially outwardly projecting grooves 12 are provided.
- the locking device 14 of the rectangular recording medium 1 consists essentially of four retaining pillars 16, which are arranged in an equally large distance from the center 15 of the bottom 2. Between the holding pillars 16, an air gap 25 is provided crosswise in each case.
- the retaining pillars 16 have a thickening from outside to inside outer contour, so that between the underside of the bottom 2 and the largest cross section of the retaining pillar 16, a contact surface 17 is created, which rests on the underside of the support plate 9 in the locked state.
- the design of the retaining pillars 16 and their operation can be seen. Namely, when the four retaining pillars 16 is pressed through the recess 10 of the support plate 9, they are thus radially compressed in the direction of the center 15, so that they slip through the recess 10. The existing air gap 25 thus allows this movement. As soon as the retaining pillars 16 with the contact surface 17 are pressed through the recess 10, the retaining pillars 16 snap back into their starting position, whereby the contact surface 17 on the underside of the support plate 9 and thereby the receiving carrier 1 is fixed to the support plate 9. The distance between the contact surface 17 and the bottom 8 of the bottom 2 is dimensioned such that the thickness of the support plate 9 coincides with this distance. To remove the recording medium 1 from the respective recess 10, a certain, vertically upward force is required, through which the retaining pillars 16 are compressed by the recess 10.
- the outer contour of the bottom 2 is configured rectangular and the side lengths of the recording medium 1 are adapted to the distances of the recesses 10, a plurality of recording media 1 can be fixed without abutting each other on the support plate 9. In addition, the recording medium 1 can be latched vertically from above into the respective recess 10.
- the round receiving carrier 1 ' is provided with a locking device 14, which is in the manner of a bayonet lock in the recess 10 of the support plate 9 is used.
- a locking device 14 namely a Anformung 22 is attached to a web 19 which is parallel to the bottom 8 of the bottom 2 and spaced from this.
- the Anformung 22 and the web 19 are inserted into the recess 10 and the radially projecting grooves 12 and as soon as the web 19 is arranged on the underside of the support plate 9, the recording medium 1 'can be rotated to the aligned coincidence of the web 19 with the Groove 12 dissolve so that the web 19 comes to rest on the underside of the support plate 9 and thereby the respective recording medium 1 'is reliably fixed to the support plate 9.
- FIGS. 2b and 2c The structural design of the locking device 14 of the round receiving carrier 1 'is the FIGS. 2b and 2c refer to.
- a rail-shaped projection 13 is provided in the corner regions of the receiving carrier 1.
- the rail-shaped Anformung 13 can be injection molded in the injection molding process directly in the production of the recording medium 1 to the respective inner side of the retaining fingers 3.
- the diameter of this Anformung 13 may be configured differently sized to reduce the volume of the space 4. It is also conceivable to use the Anformung 13 as a support rail for a hopefulschiebende rail 23.
- This rail 23 may be dimensioned to be different in size to adapt the space 4 to the outer contour of the workpiece 5 to be used.
- the retaining fingers 3 are bent inwards and adapted to the outer edges of the bottom 2.
- the retaining fingers 3 can also be configured rectangular.
- the slip planes 26 are inclined at an angle of 20 ° to 45 ° from the horizontal.
- the number of retaining fingers 3 is adapted to the pitch of the polygonal profile 27 of the workpiece 5, in such a way that the number of spaces 24 corresponds to the number of corners of the polygonal profile 27 or adapted thereto multiples. This means that if a hexagonal profile 27 is formed on the workpiece 5, the number of intermediate spaces 24 must be limited to six or twelve.
- FIG. 5a is a round recording medium 1'dar hire, on which only a support rib 3 is integrally formed perpendicular to the bottom 2.
- a support rib 3 is integrally formed perpendicular to the bottom 2.
- two support ribs 11 are provided, whose contour are aligned exactly aligned with the outer periphery of the bottom 2, so that the bottom 2, the retaining fingers 3 and the two attached to the retaining fingers 3 support ribs 11 include the space 4, in which the workpiece 5 - as already described - is used from above.
- one of the support ribs 11 is provided with an air gap 28, so that this support rib 11 is divided into two parts. It is understood that the support ribs 11 may optionally be completely closed or provided with one of the air gaps 28.
- the air gap 28 causes the aligned facing free ends of the two-part support rib 11 have a resilient property. For example, if a slightly larger sized workpiece 5 or a very soft and thus sensitive workpiece 5 is inserted into the space 4, or if the workpiece 5 is not aligned exactly aligned with the space 4, the support ribs 11 yield without damaging the workpiece 5 while ensuring that the workpiece 5 enters the room 4.
- FIG. 5b is the recording medium 1 'provided with a rectangular, preferably square bottom 2 and integrally formed on the retaining finger 3 supporting ribs 11 are the outer contours of the bottom 2 modeled so that the support ribs 11 form a rectangular, preferably square outer and inner contour. Also, the rectangular support ribs 11 may be provided with the air gap 28, which extends both in the embodiment of Figure 6a and in Figure 6b aligned opposite to the one holding finger 3.

Abstract
Description
Die Erfindung bezieht sich auf einen Aufnahmeträger zur Halterung von vereinzelten Werkstücken zu deren Bearbeitung und Transport nach dem Oberbegriff des Patentanspruches 1. Ein solcher Aufnahmeträger ist z.B. aus dem Patentdokument
Es ist bekannt, diverse Werkstücke, beispielsweise Schrauben, rotations- oder nichtrotationsymmetrische Wellen, Rohre, Zapfen oder dgl., zu vereinzeln, um diese nach der spanabhebenden Bearbeitung zu reinigen, zu beschichten oder zu transportieren. Zu diesem Zweck werden insbesondere von der Kunststoffindustrie runde Körbe zur Verfügung gestellt, in die das jeweilige Werkstück einlegbar ist. Diese Körbe, die als Aufnahmeträger dienen, weisen einen geschlossenen Boden auf, an dem drei oder mehrere Haltefinger senkrecht abstehen. Üblicherweise ist der Boden rund ausgestaltet und die Haltefinger sind in einem gleich groß bemessenen Abstand zueinander an dem Boden angeformt.It is known to separate a variety of workpieces, such as screws, rotationally or non-rotationally symmetrical shafts, tubes, pins or the like., To clean them after machining, to coat or to transport. For this purpose round baskets are made available in particular by the plastics industry, in which the respective workpiece can be inserted. These baskets, which serve as receiving media, have a closed bottom, on which three or more retaining fingers project vertically. Usually, the bottom is designed around and the holding fingers are integrally formed in a same sized distance from each other on the ground.
Um den Transportvorgang der einzelnen Aufnahmeträger zu vereinfachen, ist eine aus Edelstahl gefertigte Trägerplatte vorgesehen, in die eine Vielzahl von Bohrungen mit einer oder mehreren radial verlaufenden Nuten eingearbeitet sind. An dem Boden des Aufnahmeträgers ist auf der gegenüberliegenden Seite eine runde Anformung vorgesehen, an der ein Steg beabstandet und parallel zu dem Boden verläuft. Somit kann die Anformung in die Bohrung der Trägerplatte nach Art eines Bajonettverschlusses oder Hinterschneidung eingedreht werden. In jeder Bohrung ist somit einer der Aufnahmeträger fixierbar, so dass eine Vielzahl von Aufnahmeträgern auf einer gemeinsamen Trägerplatte angeordnet werden können.In order to simplify the transport process of the individual recording media, a carrier plate made of stainless steel is provided, in which a plurality of holes are incorporated with one or more radially extending grooves. At the bottom of the receiving carrier, a round Anformung is provided on the opposite side, on which a web spaced and parallel to the bottom. Thus, the Anformung can be screwed into the bore of the support plate in the manner of a bayonet catch or undercut. Thus, one of the receiving carriers can be fixed in each bore, so that a large number of receiving carriers can be arranged on a common carrier plate.
Die Trägerplatte kann dann zusammen mit den Aufnahmeträgern und den darin eingesetzten Werkstücken einer Reinigungsstation oder einem Beschichtungszentrum zugeführt werden. Das Reinigungsmittel bzw. die die Beschichtung bildenden Partikel gelangen durch die Zwischenräume, die zwischen zwei benachbarten Haltefingern und der geöffneten dem Boden gegenüberliegenden Stirnseite vorhanden sind, in das Innere und somit in Richtung des Werkstückes. Das Kunststoffmaterial der Haltefinger und des Bodens ist gegenüber den oftmals aggressiven Reinigungs- und Beschichtungsmitteln resistent und weist daher eine hohe Lebensdauer auf.The carrier plate can then be supplied together with the receiving carriers and the workpieces inserted therein a cleaning station or a coating center. The cleaning agent or the particles forming the coating pass through the intermediate spaces which are present between two adjacent holding fingers and the open end face opposite the bottom, into the interior and thus in the direction of the workpiece. The plastic material of the holding fingers and the bottom is resistant to the often aggressive cleaning and coating agents and therefore has a long service life.
Durch die
Als nachteilig hat sich zunächst herausgestellt, dass die runde Kontur des Bodens dazu führt, dass die auf der Trägerplatte vorhandenen Platzangebote nicht ausreichend und optimal ausgenützt sind, denn da die Aufnahmeträger durch Verdrehen in die Trägerplatte nach Art des Bajonettverschlusses einzurasten sind, können benachbarte Aufnahmeträger nicht unmittelbar aneinander anliegen. Folglich entsteht zwischen den benachbarten Aufnahmeträgern ein Zwischenraum.A disadvantage has initially been found that the round contour of the floor causes the space available on the support plate are not sufficiently and optimally utilized, because as the recording media are to be engaged by twisting in the carrier plate on the type of bayonet lock, adjacent recording media not lie directly against each other. As a result, a space is created between the adjacent recording media.
Darüber hinaus hat sich herausgestellt, dass die Haltefinger nach einer bestimmten Verwendungsdauer ihre Stabilität verlieren und ausleiern. Die auf das Werkstück einwirkenden Reinigungs- und Beschichtungsmittel üben nämlich oftmals einen erheblichen Druck auf die Haltefinger aus, der dazu führt, dass diese aus ihrer Ausgangslage verbogen sind. Des Weiteren sind die einzelnen Aufnahmeträger zu umgreifen. Dies erfolgt beispielsweise mittels Robotern, die eine entsprechende Kraft auf die Haltefinger ausüben, so dass auch durch diese Bearbeitungs- und Behandlungskräfte die Formstabilität der Haltefinger reduziert ist. Wenn jedoch die Haltefinger ihre ursprüngliche Position nicht länger einnehmen, dann wackelt das Werkstück im Inneren des Aufnahmeträgers und wird durch dieses nicht zuverlässig gehalten. Dies kann zu Beschädigungen oder zu einer unsachgemäßen Beschichtung und Reinigung des Werkstückes führen.In addition, it has been found that the holding fingers lose their stability and leach after a certain period of use. The cleaning and coating agents acting on the workpiece often exert a considerable pressure on the holding fingers, which causes them to be bent out of their initial position. Furthermore, the individual recording media are to be encompassed. This is done for example by means of robots which exert a corresponding force on the retaining fingers, so that the dimensional stability of the retaining fingers is also reduced by these processing and treatment forces. However, if the holding fingers no longer assume their original position, then the workpiece wobbles inside the receiving carrier and is not held reliably by this. This can lead to damage or improper coating and cleaning of the workpiece.
Es ist daher Aufgabe der Erfindung, einen Aufnahmeträger der eingangs genannten Gattung bereitzustellen, der zum einen als Massenartikel auf einfache und kostengünstige Weise herstellbar ist und der zum anderen eine lange Lebensdauer sowie eine hohe Formstabilität, insbesondere für die Haltefinger, aufweist.It is therefore an object of the invention to provide a recording medium of the type mentioned, on the one hand as a mass-produced in a simple and cost-effective manner and on the other a long life and high dimensional stability, especially for the holding fingers having.
Darüber hinaus soll ein Aufnahmeträger zur Verfügung gestellt werden, der möglichst unmittelbar benachbart zu anderen Aufnahmeträgern auf einer Trägerplatte angeordnet werden kann, so dass zwischen den benachbarten Aufnahmeträgern kein unnötiger Zwischenraum entsteht. Ferner ist es Aufgabe der Erfindung, einen Aufnahmeträger der eingangs genannten Gattung derart weiterzubilden, dass der von den Haltefingern und dem Boden eingeschlossene Raum zur Aufnahme des Werkstückes an dessen Außenkontur anpassbar ist, um das Volumen des Raumes optimal auf das Volumen des Werkstückes einstellen zu können und um das Einführen des Werkstückes zu erleichtern.In addition, a recording medium is to be made available, which can be arranged as close as possible to other recording media on a support plate, so that no unnecessary space between the adjacent recording media. Furthermore, it is an object of the invention to develop a recording medium of the type mentioned in such a way that the space enclosed by the holding fingers and the bottom space for receiving the workpiece on the outer contour is adjustable in order to adjust the volume of the space optimally to the volume of the workpiece can and to facilitate the insertion of the workpiece.
Diese Aufgaben sind erfindungsgemäß durch die Merkmale des kennzeichnenden Teils von Patentanspruch 1 gelöst.These objects are achieved by the features of the characterizing part of
Weitere vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous developments of the invention will become apparent from the dependent claims.
Es ist besonders zweckmäßig, die Formstabilität von zwei benachbarten Haltefingern durch die Anbringung einer oder mehrer voneinander beabstandeten Stützrippen zu erhöhen, die senkrecht zu der Längsachse des Aufnahmeträgers verlaufen, denn dadurch ist gewährleistet, dass die Haltefinger mittels der Stützrippen auch dann in ihrer Position fixiert sind, wenn Kräfte auf die Haltefinger, beispielsweise durch Reinigungs- und Beschichtungsmittel oder durch Betätigungskräfte von Roboterhänden, einwirken. Wenn dabei die Stützrippen im Bereich der geöffneten Stirnseite des Aufnahmeträgers angeordnet sind, werden die Haltefinger im Bereich dieser Stirnseite gegenseitig abgestützt, so dass ein Ausknicken einzelner Haltefinger vermieden werden kann, da die Formstabilität aller Haltefinger wesentlich größer ist als die Formstabilität eines einzelnen auskragenden Haltefingers. Der Aufnahmeträger ist folglich in Form eines Käfigs ausgestaltet.It is particularly useful to increase the dimensional stability of two adjacent retaining fingers by the attachment of one or more spaced apart support ribs, which are perpendicular to the longitudinal axis of the receiving carrier, because this ensures that the holding fingers are then fixed by the support ribs in position when forces act on the holding fingers, for example by cleaning and coating agents or by actuating forces of robot hands. If in this case the support ribs are arranged in the region of the open front side of the receiving carrier, the holding fingers are mutually supported in the region of this end face, so that buckling of individual holding fingers can be avoided since the dimensional stability of all holding fingers is substantially greater than that Dimensional stability of a single projecting retaining finger. The recording medium is thus configured in the form of a cage.
Die Stützrippen können in einem gemeinsamen oder in unterschiedlich zueinander verlaufenden Höhenniveaus angeordnet sein. Es ist besonders vorteilhaft, wenn mehrere Stützrippen auf einem gemeinsamen Höhenniveau konzentrisch um die Längsachse des Aufnahmeträgers angeordnet sind und wenn mehrere solcher Ebenen von Stützrippen zueinander beabstandet an den Haltefingern angebracht sind, um diese an mehreren Positionen in ihrer vorgegebenen Lage zu stabilisieren.The support ribs can be arranged in a common or in mutually different height levels. It is particularly advantageous if a plurality of support ribs are arranged at a common height level concentrically about the longitudinal axis of the receiving carrier and if several such levels of support ribs spaced from each other on the retaining fingers are mounted to stabilize them at several positions in their predetermined position.
Die Herstellungskosten solcher in Massenproduktion gefertigten Aufnahmeträger können im Kunststoff-Spritzgußverfahren erheblich reduziert werden, denn dann ist der Boden, die Haltefinger und die Stützrippen aus einem gemeinsamen Werkstoff gefertigt. Zudem können unterschiedlich große Aufnahmeträger mit entsprechenden Bodenabmessungen bzw. Längen von Haltefingern an unterschiedlich groß bemessene Werkstücke bereits im Herstellungsverfahren angepasst werden, so dass in Abhängigkeit von der Größe des aufzunehmenden Werkstückes der entsprechende Aufnahmeträger einsetzbar ist.The cost of producing such mass-produced recording media can be significantly reduced in the plastic injection molding process, because then the bottom, the retaining fingers and the support ribs made of a common material. In addition, differently sized recording media with corresponding bottom dimensions or lengths of holding fingers can be adapted to differently sized workpieces already in the manufacturing process, so that depending on the size of the male workpiece the corresponding recording medium can be used.
Dadurch, dass die Böden der Aufnahmeträger eine rechteckförmige, vorzugsweise quadratische, Kontur aufweisen, können die Aufnahmeträger zu anderen Aufnahmeträgern unmittelbar benachbart aneinanderliegend auf einer Trägerplatte positioniert werden. Somit entsteht zwischen den benachbarten Aufnahmeträgern kein Zwischenraum und die von der Trägerplatte zur Verfügung gestellte Positionierungsfläche ist optimal ausgenutzt.Due to the fact that the bottoms of the receiving carrier have a rectangular, preferably square, contour, the receiving media can be positioned adjacent to other receiving media adjacent to one another on a carrier plate. Thus, no space is created between the adjacent recording media and the positioning surface provided by the carrier plate is optimally utilized.
Darüber hinaus ist es besonders vorteilhaft, wenn in den Eckbereichen des Aufnahmeträgers eine schienenförmige Anformung vorgesehen ist, die das Volumen von den Haltefingern und dem Boden gebildeten Raumes reduziert, so dass das Volumen des Raumes optimal an das in dieses eingesetzte Werkstück anpassbar ist.Moreover, it is particularly advantageous if a rail-shaped Anformung is provided in the corner regions of the receiving carrier, which reduces the volume of the retaining fingers and the ground formed space, so that the volume of the space is optimally adapted to the workpiece inserted into this.
Gleichzeitig ist ein ausreichend groß bemessener Zwischenraum sowohl zwischen den Haltefingern als auch zwischen den parallel zueinander verlaufenden Stützrippen vorgesehen, durch den Reinigungs- oder Beschichtungsmittel in das Innere des Raumes und damit in Richtung des Werkstückes gelangen.At the same time, a sufficiently large space between the retaining fingers and between the mutually parallel support ribs intended to pass through the cleaning or coating agent into the interior of the room and thus in the direction of the workpiece.
Mittels der Arretierungseinrichtung, die auf der dem Innenraum abgewandten Stirnseite des Bodens angebracht ist, können die Aufnahmeträger in eine Aussparung, die in der Trägerplatte eingearbeitet ist, nach Art einer Hinterschneidung eingerastet werden, denn die Arretierungseinrichtung besteht aus zwei oder mehreren Haltepfeilern, zwischen denen jeweils ein Luftspalt vorhanden ist.By means of the locking device, which is mounted on the side facing away from the interior of the bottom, the recording media can be engaged in a recess which is incorporated in the support plate in the manner of an undercut, because the locking device consists of two or more holding pillars, between each an air gap is present.
Der Luftspalt weist dabei eine V-förmige oder U-förmige Innenkontur auf, durch die die Haltefinger radial, also in Richtung der Längsachse des Aufnahmeträgers weggedrückt sind, um den Außenumfang der Haltepfeiler an den Innendurchmesser der Aussparung der Trägerplatte anzupassen, so dass die Haltepfeiler durch die Aussparung auf einfache Art durchdrückbar und nach dem Verrastungsvorgang zuverlässig in der Aussparung gehalten sind.The air gap in this case has a V-shaped or U-shaped inner contour through which the retaining fingers are pushed radially, ie in the direction of the longitudinal axis of the receiving carrier to adjust the outer periphery of the retaining pillars to the inner diameter of the recess of the support plate, so that the retaining pillars the recess in a simple way durchdrückbar and are reliably held in the recess after Verrastungsvorgang.
Des Weiteren weisen die Haltepfeiler eine von außen nach innen sich verdickende Außenkontur auf, so dass beim Einführen der Aufnahmepfeiler in die Aussparung der Trägerplatte die Haltepfeiler in Richtung des Zentrum des Bodens zusammengedrückt sind und sobald die Haltepfeiler die Aussparung verlassen, wieder nach außen federn, wodurch eine zuverlässige Befestigung der Aufnahmeträger an der Trägerplatte sichergestellt ist. Die Haltepfeiler können demnach senkrecht von oben in die Aussparung der Trägerplatte eingesetzt werden, so dass der Boden eine rechteckförmige Außenkontur aufweisen kann, denn ein Verdrehen der Aufnahmeträger ist nicht länger erforderlich. Folglich gelangen die Außenflächen der Haltefinger in Anlage mit den Außenflächen von Haltefingern der benachbarten Aufnahmeträger, so dass zwischen diesen kein Zwischenraum entsteht.Furthermore, the retaining pillars have a thickening from outside to inside outer contour, so that upon insertion of the receiving pillars in the recess of the support plate, the retaining pillars are compressed in the direction of the center of the bottom and as soon as the retaining pillars leave the recess, spring back outwards a reliable attachment of the recording medium is secured to the support plate. Accordingly, the retaining pillars can be inserted vertically from above into the recess of the carrier plate, so that the bottom can have a rectangular outer contour, since twisting of the receiving carrier is no longer necessary. Consequently, the outer surfaces of the retaining fingers come into contact with the outer surfaces of retaining fingers of the adjacent receiving carrier, so that there is no gap between them.

Der Boden 2 und die Haltefinger 3 begrenzen einen Raum 4, in dem das Werkstück 5 eingesetzt ist. Da zwischen zwei benachbarten Haltefingern 3 ein Zwischenraum 24 vorgesehen ist und die dem Boden 2 gegenüberliegende Stirnseite des Aufnahmeträgers 1 offen ausgestaltet ist, kann durch diese Öffnungen Reinigungs- oder Beschichtungsmittel in Richtung des Werkstückes 5 eindringen.The

Um die Stabilität der Haltefinger 3, insbesondere durch auf diese einwirkenden Kräfte zu erhöhen, ist zwischen zwei benachbarten Haltefingern 3 jeweils eine Stützrippe 11 vorgesehen, die konzentrisch um und senkrecht zu der Längsachse 3' des Aufnahmeträgers 1 verlaufen. Es ist besonders vorteilhaft, wenn die Stützrippen 11 im Bereich der von außen zugänglichen Öffnungen zwischen den Haltefingern 3, also im Bereich der freien Enden der Haltefinger 3, angeordnet sind und wenn die Stützrippen 11 auf einem gemeinsamen Höhenniveau verlaufen, denn dadurch ist gewährleistet, dass die freien Enden der Haltefinger 3 gegenseitig abgestützt sind. Um die Stabilität der Haltefinger 3 weiter zu erhöhen, sind weitere parallel zueinander verlaufende Stützrippen 11 zwischen zwei benachbarten Haltefingern 3 vorgesehen. Zwischen den Stützrippen 11 und den Haltefingern 3 sind die Zwischenräume 24 vorhanden, durch die eine ausreichende Menge von Reinigungs- und/oder Beschichtungsmittel in den Raum 4 in Richtung der Werkstücke 5 gelangt.In order to increase the stability of the retaining

Die Arretiereinrichtung 14 des rechteckförmigen Aufnahmeträgers 1 besteht nämlich im Wesentlichen aus vier Haltepfeilern 16, die in einem gleich groß bemessenen Abstand zu dem Zentrum 15 des Bodens 2 angeordnet sind. Zwischen den Haltepfeilern 16 ist kreuzweise jeweils ein Luftspalt 25 vorhanden. Die Haltepfeiler 16 weisen eine von außen nach innen sich verdickende Außenkontur auf, so dass zwischen der Unterseite des Bodens 2 und dem größten Querschnitt des Haltepfeilers 16 eine Anlagefläche 17 geschaffen ist, die auf der Unterseite der Trageplatte 9 im eingerasteten Zustand anliegt.The locking

Da die Außenkontur des Bodens 2 rechteckförmig ausgestaltet ist und die Seitenlängen der Aufnahmeträger 1 an die Abstände der Aussparungen 10 angepasst sind, können mehrere der Aufnahmeträger 1 ohne Zwischenraum aneinander anliegend auf der Trägerplatte 9 fixiert werden. Zudem sind die Aufnahmeträger 1 senkrecht von oben in die jeweilige Aussparung 10 einrastbar.Since the outer contour of the
Im Gegensatz dazu ist der runde Aufnahmeträger 1' mit einer Arretiereinrichtung 14 versehen, die nach Art eines Bajonettverschlusses in die Aussparung 10 der Trägerplatte 9 einsetzbar ist. An der Arretiereinrichtung 14 ist nämlich eine Anformung 22 mit einem Steg 19 angebracht, der parallel zu der Unterseite 8 des Bodens 2 und beabstandet zu diesem verläuft. Die Anformung 22 und der Steg 19 werden in die Aussparung 10 und den radial abstehenden Nuten 12 eingeführt und sobald der Steg 19 auf der Unterseite der Trägerplatte 9 angeordnet ist, kann der Aufnahmeträger 1' verdreht werden, um die fluchtende Übereinstimmung des Steges 19 mit der Nut 12 aufzulösen, so dass der Steg 19 auf der Unterseite der Trägerplatte 9 zur Anlage gelangt und dadurch der jeweilige Aufnahmeträger 1' zuverlässig mit der Trägerplatte 9 fixiert ist.In contrast, the round receiving carrier 1 'is provided with a

Um zu verhindern, dass das in den Raum 4 des Aufnahmeträgers 1 eingesetzte Werkstück 5 während des Reinigungs- oder Beschichtungsvorganges zwischen den Haltefingern 3 hin und her schlägt, ist in den Eckbereichen des Aufnahmeträgers 1 eine schienenförmige Anformung 13 vorgesehen. Die schienenförmige Anformung 13 kann dabei im Spritzgußverfahren unmittelbar bei der Herstellung des Aufnahmeträgers 1 an die jeweilige Innenseite der Haltefinger 3 angespritzt sein. Es ist jedoch auch möglich, wie dies in

An den Aufnahmeträger 1 " können auch die Stützrippen 11 angeformt sein, die zwischen zwei benachbarten Haltefingern 3 verlaufen. Es ist jedoch darauf zu achten, dass der Abstand der Stützrippen 11 von der Längsachse 3' einen derart groß bemessenen Abstand einnimmt, dass dadurch die Rutschbewegung des Werkstückes 5 in dem Zwischenraum 24 nicht behindert ist. Wenn demnach die Stützrippen 11 auf den Außenseiten der Haltefinger 3 angeordnet sind, ist ein solcher Abstand gewährleistet, dass das Werkstück 5 in den Aufnahmeträger 1 " ein- und ausschiebbar ist. Dies ist mit Hilfe eines Bewegungspfeils in
Die Gleitebenen 26 sind in einem Winkel von 20° bis 45° aus der Horizontalen geneigt. Darüberhinaus ist die Anzahl der Haltefinger 3 an die Teilung des Mehrkantprofiles 27 des Werkstückes 5 angepasst, und zwar derart, dass die Anzahl der Zwischenräume 24 der Anzahl der Ecken des Mehrkantprofiles 27 oder einem daran angepassten Vielfachen entspricht. Dies bedeutet, wenn an dem Werkstück 5 ein Sechskantprofil 27 angeformt ist, dann ist die Anzahl der Zwischenräume 24 auf sechs oder zwölf zu begrenzen.The slip planes 26 are inclined at an angle of 20 ° to 45 ° from the horizontal.

Desweiteren ist einer der Stützrippen 11 mit einem Luftspalt 28 ausgestattet, so dass diese Stützrippe 11 zweigeteilt ist. Es versteht sich, dass die Stützrippen 11 wahlweise vollständig geschlossen oder mit einem der Luftspalte 28 versehen sein können. Der Luftspalt 28 bewirkt, dass die sich fluchtend gegenüberstehenden freien Enden der zweigeteilten Stützrippe 11 eine federnde Eigenschaft aufweisen. Wenn beispielsweise ein etwas größer bemessenes Werkstück 5 oder ein sehr weiches und damit empfindliches Werkstück 5 in den Raum 4 eingesetzt wird, bzw. wenn das Werkstück 5 nicht exakt fluchtend zu dem Raum 4 ausgerichtet ist, können die Stützrippen 11 nachgeben, ohne dabei das Werkstück 5 zu beschädigen und gleichzeitig ist gewährleistet, dass das Werkstück 5 in den Raum 4 gelangt.Furthermore, one of the
