Abstract

Bei einem Verfahren zum Herstellen von Kerzen mit Docht durch Eingießen von flüssigem Wachs in eine oben offene Gießform wird zunächst der Docht von oben durch die Gießform gespannt, festgeklemmt und abgeschnitten und hierauf das flüssige Wachs eingefüllt, worauf der erstarrte Kerzenkörper nach Freigabe des eingespannten Dochtes nach oben ausgestoßen wird. Die Vorrichtung zur Durchführung dieses Verfahrens sieht ein von oben in die Gießform (5) eintauchendes Dochtrohr (12) zum Einbringen eines von einer Dochtspule abziehbaren Dochtes (10) vor. Zum Festklemmen des unteren Dochtendes ist im Gießformboden (14) ein Klemmstift verschiebbar, während zum Festhalten und Spannen des Dochtes oberhalb der Gießform eine einschwenkbare Klemmzange (50) vorgesehen ist.In a method for manufacturing candles with a wick by pouring liquid wax into a casting mold open at the top, the wick is first stretched, clamped and cut from above through the casting mold, and then the liquid wax is poured in, after which the solidified candle body after releasing the clamped wick is ejected above. The device for carrying out this method provides a wick tube (12), which dips into the casting mold (5) from above, for introducing a wick (10) which can be pulled off a wick spool. To clamp the lower end of the wick, a clamping pin can be displaced in the casting mold base (14), while a swiveling clamp (50) is provided above the casting mold to hold and tension the wick.

durch einen nachträglichen Vorschub des Dochtes geschehen, um diesen über den Rohrfortsatz hinausstehen zu lassen. Dazu kann ein einfaches Vorschubwerkzeug (nicht sichtbar) oberhalb des Dochtrohres am Docht angreifen, z. B. mittels Greifern, Mitnehmerwalzen od. dgl. Andererseits besteht bei insbesondere ungewachsten Dochten auch die Möglichkeit, den Rohrfortsatz 17 auf einer Seite von unten her bei 25 aufzuschlitzen, damit der Docht an dieser Stelle für ein Klemmorgan frei zugänglich ist und dieses ihn festklemmen kann. In diesem Fall kann auf einen nachträglichen Dochtvorschub verzichtet werden.done by a subsequent advance of the wick to make it protrude beyond the tubular extension allow. A simple feed tool (not visible) can be used above the wick tube on the wick attack, e.g. B. od by means of grippers, driver rollers Wicks also have the option of slitting the tubular extension 17 on one side from below at 25, so that the wick is freely accessible at this point for a clamping member and this can clamp it. In this case, a subsequent wick advance can be dispensed with.

Eine vorteilhafte Klemmeinrichtung ist in F i g. 2 dargestellt. Diese ist sowohl für vorgeschobenen Docht als auch in Verbindung mit geschlitztem Rohrfortsatz 17 brauchbar. Dabei ist ein Klcmmstift 30 im Gießformboden 14 horizontal verschiebbar gelagert. Er durchsetzt das Hubrohr 16. das einen Längsschlitz 31 aufweist, und ist an das freie Dochtende 32 ansetzbar, das von ihm bei geschlitztem Rohrfortsatz (linke Gießform, Fig. 2) gegen dessen Innenwand gedrückt wird, bis das Dochtrohr hochgefahren wird, worauf der Klemmstift das Dochtende gegen die Innenwand des Hubrohres 16 anpreßt (rechte Gießform, Fig.2). Damit das Dochtende auch während des Anhebens des Dochtrohres sicher festgehalten wird, ist es wichtig, daß die Reibung zwischen Dochtende und Rohrfortsatz meFldichjjeringer ist als zwischen Dochtende und Klemmstift. ^ ~~—-—_An advantageous clamping device is shown in FIG. 2 shown. This is for both advanced wick and can also be used in conjunction with a slotted tubular extension 17. There is a clamping pin 30 in the bottom of the casting mold 14 mounted horizontally displaceable. It penetrates the lifting tube 16, which has a longitudinal slot 31, and can be attached to the free end of the wick 32, which by it with a slotted tubular extension (left casting mold, Fig. 2) against the inner wall of which is pressed until the wick tube is raised, whereupon the clamping pin pushes the wick end presses against the inner wall of the lifting tube 16 (right casting mold, FIG. 2). So that the end of the wick too is held securely while lifting the wick tube, it is important that the friction between Wick end and tubular process meFldichjjeringer is as between the end of the wick and the clamping pin. ^ ~~ —-—_

Ist ein über den Rohrfortsatz hianusgeschobenes Dochtende vorhanden, dann drückt der Klemmstift sogleich dieses Ende gegen das Hubrohr.If there is a wick end pushed over the tubular extension, the clamping pin presses immediately this end against the lifting tube.

Zum Betätigen der Klemmorgane ist eine unter die jeweils in der Bedochtungsstation C befindliche Gießform einfahrbare Betätigungseinrichtung vorgesehen. Beim Ausführungsbeispiel ist diese für einen Formenkasten mit zwei Formenzeilen ausgelegt. Die zum Klemmen der Dochtenden 32 dienenden Klemmstifte sind in Richtung Klemmstellung federbelastet, so daß der Klemmvorgang selbsttätig erwirkt wird. Dazu sind zwischen den hintereinanderliegenden Gießformen jedes Formenkastens die Klemmstifte 30, 30' an Klemmleisten 34, 34' so befestigt, daß die Klemmstifte voneinander abgekehrt und eine Druckfeder 35 die beiden Klemmleisten verbindet, derart, daß diese Druckfeder die Leisten mit den Klemmstiften in die Klemmstellungen auseinanderdrückt. Um diese Kiemmstellung, beispielsweise zum Einführen eines Dochtes, zu lösen, ist ein Öffnungsaggregat 36 vorgesehen. Aus Zweckmäßigkeitsgründen ist dieses Aggregat in Doppelbauweise ausgeführt und wirV*. mit den beiden Formenzeilen des jeweils eingeschobenen Formenkastens zusammen. Im wesentlichen besteht das Aggregat aus einem Kipphebel 38 bzw. 38', der auf einem Querlager 39 kippbar gelagert ist. Mit dem einen Ende 40 bzw. 40' steht dieser Kipphebel mit einem Druckkolben 41 bzw. 41' eines Druckzylinders 42 bzw. 42' in Verbindung. Beim Doppelaggregat sind diese beiden Druckzylinder mittels eines Querstückes 43, an dem auch ein Hubzylinder 33 angreift, miteinander verbunden. Das obere Ende 45 bzw. 45' des Kipphebels reicht bis zur Höhe des Klemmstiftes bzw. der zugehörigen Klemmleiste 34 bzw. 34'. Zur Verbindung mit dem Kipphebel ist ein von der Leiste abstehender Druckstift 46 bzw. 46' vorgesehen.To actuate the clamping members, an actuating device that can be retracted under the casting mold located in the wicking station C is provided. In the exemplary embodiment, this is designed for a mold box with two rows of molds. The clamping pins used to clamp the wick ends 32 are spring-loaded in the direction of the clamping position, so that the clamping process is effected automatically. For this purpose, the clamping pins 30, 30 'are attached to clamping strips 34, 34' between the casting molds lying one behind the other in each mold box so that the clamping pins face away from each other and a compression spring 35 connects the two clamping strips, in such a way that this compression spring moves the strips with the clamping pins into the clamping positions pushes apart. In order to solve this clamping position, for example for inserting a wick, an opening unit 36 is provided. For reasons of convenience, this unit is designed in double construction and wirV *. with the two rows of molds in the respective inserted mold box. The unit essentially consists of a rocker arm 38 or 38 ', which is tiltably mounted on a transverse bearing 39. At one end 40 or 40 ', this rocker arm is connected to a pressure piston 41 or 41' of a pressure cylinder 42 or 42 '. In the case of the double unit, these two pressure cylinders are connected to one another by means of a crosspiece 43, on which a lifting cylinder 33 also engages. The upper end 45 or 45 'of the rocker arm extends to the level of the clamping pin or the associated terminal strip 34 or 34'. A pressure pin 46 or 46 'protruding from the bar is provided for connection to the rocker arm.

Da in der Bedochtungsstation der Klemmstift 30 zum Einbringen des Dochtes zurückgestellt sein muß (linke Gießform, F i g. 2), wird der Durckkolben 41 ausgefahren und der Kipphebel mit seinem oberen Ende 45 auf den Druckstift 46 aufgedrückt, um die Klemmleiste 34 mit dem Klemmstift entgegen der Druckfeder zurückzuschieben. Ist der Docht in die jetzt freie Pistonrohrbohrung eingebracht, wird zum Festklemmen des Dochtendes 32 der Druckzylinder 42 entlastet bzw. der Druckkolben 41 zurückbewegt, worauf die Druckfeder 35 den Klemmstift 30 wieder in die Klemmstellung schieben kann. Ist das Dochtendc festgeklemmt, kann das Dochtrohr hochgefahren werden. Hat es die obere Endstellung erreicht, fällt eine zugehörige Klemmzange 50 ein, die auf der Seitenwand 8 der Füllrinne 9 schwenkbar gelagert ist. Diese Klemmzange erfaßt den Docht und hält ihn an seinem oberen Ende fest, worauf ein Trennmesser 51, das beispielsweise mittels eines Schwenkarmes 52 am Führungsstück 19 gelagert ist, einschwenkt und den Docht dicht unterhalb des Dochtrohrfortsatzes 17 abtrennt. Der abgeschnittene Docht ist jetzt frei und zentriert in der Gießform gehalten, die nunmehr in Richtung Füllstation weitertransportiert werden kann (rechte Gießform des Formkastens Γ, F i g. 1 oder F i g. 2). Da jede Gießform mit einem in die Klemmstellung federbelasteten Klemmstift ausgerüstet ist, bleibt der Docht an seinem unteren Ende auch weiterhin festgeklemmt.
Sind die beiden Formenzeilen 3, 5 eines Formenkastens, wie Γ, auf diese Weise mit Dochten bespannt, dann wird zu seinem weiteren Vorrücken das Doppclöffnungs??gregat 36 mittels des Hubzylinders 33 aus ._ der Betriebsstellung ausgefahren und um einen Takt Zurückgesetzt, worauf dann das Aggregat mit dem Kipphebel 40' die inzwischen in die Station C nachgerückte Gießform des folgenden Formenkastens zum öffnen des Klemmstiftes 30' übernimmt. Ist diese Gießform bedochtet und der Docht festgeklemmt, rückt das Aggregat mit dem Formenkasten einen Takt vor, so daß jetzt die hintere Gießform die Bedochtungsstelle erreicht und ihr Klemmstift 30 mit dem Kipphebe! 38 in Wechselwirkung treten kann. Das Einfüllen des flüssigen Wachses in die Gießformen erfolgt erst dann, wenn sich ein ganzer Formenkasten 1" mit seiner Füllrinne in der Füllstation D befindet.Since the clamping pin 30 must be reset in the wicking station to insert the wick (left mold, Fig. 2), the pressure piston 41 is extended and the rocker arm is pressed with its upper end 45 on the pressure pin 46 to connect the terminal strip 34 with the Push back the clamping pin against the compression spring. If the wick is inserted into the now free piston tube bore, the pressure cylinder 42 is relieved or the pressure piston 41 is moved back to clamp the wick end 32, whereupon the pressure spring 35 can push the clamping pin 30 back into the clamping position. Once the wick end is clamped, the wick tube can be raised. Once it has reached the upper end position, an associated clamping tong 50 falls in, which is pivotably mounted on the side wall 8 of the filling channel 9. These clamping pliers grasp the wick and hold it at its upper end, whereupon a cutting knife 51, which is mounted for example by means of a swivel arm 52 on the guide piece 19, swivels in and cuts off the wick just below the wick tube extension 17. The cut wick is now held free and centered in the casting mold, which can now be transported further in the direction of the filling station (right casting mold of the molding box Γ, FIG. 1 or FIG. 2). Since each casting mold is equipped with a clamping pin spring-loaded into the clamping position, the wick remains clamped at its lower end.
If the two rows of molds 3, 5 of a mold box, such as, are covered with wicks in this way, then the double opening unit 36 is extended from the operating position by means of the lifting cylinder 33 by means of the lifting cylinder 33 and is set back by one cycle the unit with the rocker arm 40 'takes over the casting mold, which has meanwhile moved into station C, of the following mold box to open the clamping pin 30'. Once this casting mold has been wicked and the wick is clamped in place, the unit with the mold box advances one cycle so that the rear mold now reaches the perforated area and its pin 30 with the tilting lever! 38 can interact. The filling of the liquid wax into the casting molds only takes place when a complete mold box 1 ″ with its filling channel is in the filling station D.

Die gefüllten Gießformen werden sodann aus der Füllstation entfernt und zum Abkühlen des Kerzenwachses abgesetzt oder zweckmäßig durch eine unter dem Einfluß von Kühlluft- oder -wasser stehende Kühlstrecke transportiert. Nach dem Erstarren des Wachses werden die Gießformen in die Ausstoßstation E(F i g. 3) gebracht, in der eine Ausstoßeinrichtung 60 in Tätigkeil ist Ein Hubzylinder 61 erfaßt hier mit seiner Hubplatte 62 das bzw. die Hubrohre 16 der Gießformen und drückt über den bzw. die Pistonköpfe 15 die Ke. .-en nach oben, bis die Hubplatte am Gießformboden 14 zum Anschlag kommt Gleichzeitig sind Vorkehrungen getroffen, daß die noch festgeklemmten Dochtenden 32 rechtzeitig gelöst werden. Ein einfache Möglichkeit be-The filled casting molds are then removed from the filling station and set down to cool the candle wax or expediently transported through a cooling section under the influence of cooling air or water. After the wax has solidified, the casting molds are brought into the ejection station E ( FIG. 3), in which an ejector 60 is in action or the piston heads 15 the Ke. . -en upwards until the lifting plate comes to a stop on the casting mold bottom 14. At the same time, precautions have been taken to ensure that the still clamped wick ends 32 are released in good time. An easy way to

Damit die Klemmstifte während des Anhebens der Hubplatte den Anhub der Hubrohre der Pistonköpfe nicht behindern, sind in den Hubrohren die Längsschlitze 31 vorgesehen.is that the lifting plate 62 is equipped with opening wedges 64 when the lifting plate is raised Reach behind the terminal strips and thus also push back the terminal pins. So that the clamping pins during when lifting the lifting plate do not hinder the lifting of the lifting tubes of the piston heads, are in the lifting tubes the longitudinal slots 31 are provided.

Sofern sich in der Füllrinne ein überstehender Wachskuchen befinden sollte, wird dieser vor dem Anheben der Kerzen in üblicher Weise entfernt. Die angehobenen Kerzen werden oben von Greifern erfaßt und ausgetragen, nachdem vorher zweckmäßig gleichzeitig mit dem Abscheren des Wachskuchens auch die oberen Dochtenden abgetrennt worden sind. Ebenfalls werdenIf there is a protruding wax cake in the filling channel, this is done before lifting the candles removed in the usual way. The raised candles are picked up by grippers at the top and discharged, after previously, it is also practical to shear off the wax cake at the same time as the upper ones Wick ends have been severed. Also be

Falls die Pistonköpfe 15 mit ihren Hubrohren 16 nicht selbsttätig unter dem Einfluß ihres Eigengewichtes in die Ausgangsstellung zurückkehren, besorgen diese Rückstellung aie Dochtrohre.the clamping tongs 50 released. After the candles have been ejected, the ejector device is moved back into the starting position and the casting molds are brought back into the wicking station. If the piston heads 15 with their lifting tubes 16 do not automatically return to the starting position under the influence of their own weight, the wick tubes take care of this reset.

Die Erfindung ist nicht nur zum Gießen von langen Spindelkerzen, sondern auch zur Herstellung Stumpenförmiger und großkalibriger Kerzen besonders geeignet. Das beschriebene Bedochten von Gießformen läßt sich auch in Verbindung mit größeren Blockformen, die von Hand oder mittels automatisch arbeitenden Transportmitteln bewegt werden, gut einsetzen. Anstelle der beschriebenen Klemm- und Öffnungsmechanik für das untere Dochtende kann jeder Gießform auch ein Klemmstift mit einer eigenen, unabhängigen Druckfeder zugeordnet sein, der durch ein einfaches Rückstellorgan, beispielsweise einen einfahrenden Öffnungskeil, ähnlich dem Öffnungskeil 64 der F i g. 3, aus der Klemmstellung gelöst werden kann. Sind die Gießformen zeilenweise angeordnet, dann werden die einzelnen Betätigungsorgane soweit als möglich zusammengefaßt und durch einen gemeinsamen Antrieb in Gang gesetzt. Die gezeigte einzeilige Bedochtungsvorrichtung läßt sich auch als Zwillings- oder Mehrzeilenvorrichtung ausbilden. Arbeiten die Dochtrohre mehrerer Zeilen gleichzeitig, so umfaßt auch der Vorschubtakt diese Zeilenanzahl, »'odurch eine Erhöhung der Durchsatzleistung erreicht werden kann.The invention is not only for casting long spindle candles, but also for making pillar-shaped candles and large-caliber candles are particularly suitable. The described drenching of casting molds can can also be used in conjunction with larger block molds that are made by hand or by means of automatically operating means of transport be moved, use them well. Instead of the described clamping and opening mechanism for the lower end of the wick, each mold can also have a clamping pin with its own independent compression spring be assigned, which by a simple return element, for example a retracting opening wedge, similar to the opening wedge 64 of FIG. 3, out of the clamped position can be solved. If the molds are arranged in rows, then the individual actuators as far as possible combined and set in motion by a common drive. the The single-line wicking device shown can also be designed as a twin or multi-line device. If the wick tubes work on several lines at the same time, the feed rate also includes this number of lines, »'O can be achieved by increasing the throughput.

The invention relates to a method for producing candles with wicks, in particular spindle candles, by casting in a casting mold that is open at the top according to the preamble of claim 1.

In the case of a device of this type known here (DE-PS 23 11 699), the wick inserted into the casting mold from below through a piston piston is ejected before the wick The candle is pulled up and held under tension in the center of the mold before the liquid wax is poured into the mold. In addition the wick coils must be accommodated below the casting mold, which is the case with larger mold boxes Difficulties is connected The candle itself must be raised far above the mold, including a long piston piston with corresponding Hu'iFeinrichlung and a candle clamping device are required. If the latter does not work exactly, it becomes the desired one Wick tension not reached. In another device for pouring candles (DE-PS 23 11 700) the casting molds are combined in a small number line by line to form molding boxes, which are continuously or in cycles one after the other to a filling station, a refilling station and after cooling and solidification the candles are fed to an ejection station. However, this known casting plant is only for production Stem-shaped candles, into which the wick is added afterwards is threaded, suitable

The invention is therefore based on the object of a method and a device for producing Specify candles, with the wick, especially also for long spindle candles, precisely centered before pouring Position and can be introduced into the mold under full tension.

According to a further task, the device is designed so that it is particularly suitable for wetting of arranged in lines and moving cyclically or continuously from one station to the other Casting molds are suitable.

According to the invention, this object is achieved by a method solved with the characterizing features according to claim 1.

The device for carrying out this method is characterized by the features according to patent claim 3.

Further features of the invention are claimed in the remaining subclaims

The method according to the invention makes it possible to use a casting mold in a simple and rapid manner to insert and tension a precisely centered wick reliably and in sufficient length, and completely independent of the process of pouring and ejecting the candles. Introducing the wick from above into the Casting mold, expediently by means of a wick tube, facilitates the work process and its monitoring. By moving the wick coils upwards, the space conditions are better solved and it can be done Relatively larger wick coils are used, as on the other hand the lower space for means of transport and improved water cooling can be used. The invention proves to be particularly advantageous Solution in connection with intermittently moving casting mold lines, whereby the wick insertion and clamping devices for each one casting mold line summarized and the casting station directly are connected upstream.

The invention is explained below with reference to exemplary embodiments which are also schematized in the drawing are shown, described in more detail. It shows

F i g. 1 shows a vertical section through a device with arranged in lines and moving step by step Casting molds,

2 shows a vertical section through casting mold bases with wick clamping devices and

3 shows a vertical section through casting mold bases with a candle ejector device.

1 shows three casting mold boxes 1, Γ, 1 "which can be transported on longitudinal bearings 2 (dashed) in the direction of arrow A. Each molding box shown has two lines 3 and 4 of casting molds 5 arranged next to one another, for example for slightly conical, relatively long spindle candles vjf. These casting molds are connected to one another at the top of a pouring opening 6 and by a pouring plate 7, which is connected to one another laterally by pouring plate 7, which is laterally supplemented by the side walls 8 to form a filling channel 9. While the mold box 1 is still in providing B is, the molding box Y is inserted in the observation station C and the molding box 1 'has the filling station D in which the liquid wax is poured achieved the advance of the mold boxes takes place for example in cycles each to a Gießformenzeile.

Instead of the two lines of casting molds 3, 4, a mold box can also have only one, three or more lines of molds include.

In the wicking station C , a wick 10 is introduced from above into the casting mold 5 by means of a wick tube 12 from a wick coil (not shown) until a stop ball 13 provided at the lower end of the wick tube strikes a piston head 15 closing off the casting mold base 14, this piston head is m: . its lifting tube 16 in the casting mold bottom for lifting the solidified candle displaceable and sealed accordingly. The wick tube 12 also has a tube extension 17 protruding beyond the stop ball 13 (FIG. 2). While the actual wick tube 12 is calibrated so that a wick waxed or unwaxed therein can be easily guided, the tube extension 17 is suitably narrowed to the diameter of the wick so that the wick is held therein by frictional engagement and is dragged along with it. The wicking tube (not shown) in a stationary guide piece 19, for example by means of a pressure cylinder, a slide bush 20 de upper acts on the wick tube, correspondingly far movable up and down. A shock spring 23 arranged between this sliding bush 20 and a collar 21 fixed on the wick tube enables a stop compensation when the stop ball 13 hits the piston head 15.

During its dipping movement into the casting mold, the wick tube takes with it the wick that is being unwound from the wick reel, for which purpose it is generally sufficient that the wick is held in the tube extension 17 with frictional engagement. Since the wick should not protrude beyond the pipe extension Yt for trouble-free insertion into the piston head 15 and the lifting tube 16, it is necessary to clamp the wick after this insertion process to release it from a clamping member. In the case of waxed wicks in particular, this can be the case
