Abstract

In a process to manufacture heavy-duty paper sacks for e.g. cement powder, the paper web is cut to lengths that are folded and glued into open-ended essentially tubular units, then folded flat and placed on a stack. A rotary pick-up (3) assembly lifts the top sack from the pile and transfers it sideways to a conveyer to e.g. the bag bottom-closing stage. The speed of the rotary pick-up is adjustable to the speed of the conveyer.

Description

Die Erfindung betrifft eine Bodenlegevorrichtung nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren nach dem Oberbegriff des Anspruchs 5.The invention relates to a Bodenlegevorrichtung according to the preamble of claim 1 and a method according to the preamble of claim. 5

Diese Vorrichtungen sind bekannt und beispielsweise in der Druckschrift DE 103 06 615.2 (Offenlegungstag 02.09.2004) dargestellt. Oft werden mit ihnen Papiersäcke, beispielsweise Zementsäcke, hergestellt. Zu diesem Zweck werden vorzugsweise Kreuzbodenventilsäcke verwendet.These devices are known and for example in the document DE 103 06 615.2 (Disclosure Day 02.09.2004). Often with them paper sacks, such as cement bags made. For this purpose, preferably cross bottom valve bags are used.

Bei der Herstellung dieser Säcke finden Schlauchstücke, die in der Regel zuvor von einer Schlauchmaschine gebildet wurden, Verwendung. Die Schlauchstücke werden vorzugsweise in Stapelform gespeichert und anschließend einer vorwiegend translatorischen Fördervorrichtung zugeführt. Diese Fördervorrichtung ist oder bildet einen Teil der Fördervorrichtungen, mit denen das Schlauchstück durch die verschiedenen Bearbeitungsstationen des Bodenlegers transportiert wird.In the production of these bags hose pieces, which were previously formed by a hose machine usually find use. The pieces of tubing are preferably stored in stack form and then fed to a predominantly translatory conveying device. This conveyor device is or forms part of the conveying devices with which the hose section is transported through the different processing stations of the bottom layer.

Bei der Zuführung der Schlauchstücke zu den Fördervorrichtungen spielen sogenannte Rotationsanleger eine entscheidende Rolle. Sie entnehmen die Schlauchstücke dem Schlauchstückstapel und führen ihn der translatorischen Fördervorrichtung zu. Das zentrale Bauteil des Rotationsanlegers ist ein Rotor der in unmittelbarer Nähe des Schlauchstückstapels angebracht ist und der über Aufnahmevorrichtungen für die Schlauchstücke verfügt. Ein solcher Rotationsanleger ist für den Anwendungsfall des Anlegens von einfachen Papierbögen in der EP 0 405 107 A1 gezeigt.When supplying the hose pieces to the conveyors so-called rotary feeder play a crucial role. They take the pieces of hose the hose piece stack and lead him to the translatory conveyor. The central component of the rotary feeder is a rotor which is mounted in the immediate vicinity of the hose piece stack and which has receiving devices for the hose pieces. Such a rotary feeder is for the application of the application of simple paper sheets in the EP 0 405 107 A1 shown.

Die Fördervorrichtungen weisen oft genau definierte Stellen zur Aufnahme der Schlauchstücke auf. Auf diese Weise wird gewährleistet, dass die Schlauchstücke an den richtigen Stellen der Fördervorrichtung zum Liegen kommen. Tun sie das nicht, werden sie von den Werkzeugen der Bearbeitungsstationen an der falschen Stelle bearbeitet, so dass Qualitätsmängel der Säcke wie Undichtigkeiten zu beklagen sind. Oft sind ganz verschiedene Förderbandsysteme Bestandteil der vorgenannten Fördervorrichtungen. So ist es außerordentlich vorteilhaft, zunächst ein separates Förderbandsystem vorzusehen, dessen Aufgabe lediglich in der Übernahme der Schlauchstücke vom Rotationsanleger und in der Weitergabe an eine Ausrichtungsvorrichtung besteht. In der Ausrichtungsvorrichtung werden die Schlauchstücke an den für die Ausrichtung der Schlauchstücke vorgesehenen Stellen positioniert. Die Ausrichtungsvorrichtung übergibt dann die Schlauchstücke an weitere Förderbandsysteme, welche die Schlauchstücke den Bearbeitungsstationen zuführen.The conveyors often have well-defined locations for receiving the hose pieces. In this way, it is ensured that the hose pieces come to rest at the right places of the conveyor. If they do not do so, they will be processed by the tools of the processing stations in the wrong place, so that quality defects of the bags such as leaks are to be lamented. Often quite different conveyor belt systems are part of the aforementioned conveying devices. Thus, it is extremely advantageous initially to provide a separate conveyor belt system, whose task consists only in the acquisition of the hose pieces from the rotary feeder and in passing to an alignment device. In the alignment device, the pieces of tubing are positioned at the locations provided for the alignment of the tubing pieces. The alignment device then passes the pieces of tubing to other conveyor belt systems which supply the tubing pieces to the processing stations.

Auch beim Betrieb der gattungsgemäßen Bodenlegeeinrichtungen ist der Trend zu höheren Bearbeitungsgeschwindigkeiten ungebrochen. Bei höheren Bearbeitungsgeschwindigkeiten müssen natürlich auch die Transportgeschwindigkeiten der Schlauchstücke in dem Rotationsanleger und in der Fördervorrichtung steigen. Bei Bodenlegern des Standes der Technik werden beide vorgenannte Funktionsgruppen von einem Antrieb mit Drehmoment versorgt, so dass sich die Transportgeschwindigkeiten in beiden Funktionsgruppen gleichmäßig erhöht. Trotz dieser Tatsache hat es sich gezeigt, dass die zum Erreichen einer hohen Produktionsgeschwindigkeit nötigen Änderungen der Produktionsgeschwindigkeit dazu führen, dass die Schlauchstücke von dem Rotationsanleger mit zunehmender Ungenauigkeit an die Stellen zur Aufnahme der Schlauchstücke übergeben werden. Diesem Nachteil hoher bzw. in hohem Maße geänderter Produktionsgeschwindigkeit ist man bisher beispielsweise begegnet, indem man aufwändigere Ausrichter vorgesehen hat.Also in the operation of the generic Bodenlegeeinrichtungen the trend to higher processing speeds is unbroken. At higher processing speeds, of course, the transport speeds of the hose pieces in the rotary feeder and in the conveyor must rise. In floor levelers of the prior art, both aforementioned functional groups are supplied with torque by a drive, so that the transport speeds increase uniformly in both functional groups. Despite this fact, it has been found that the changes in the production speed necessary to achieve a high production speed lead to the hose pieces being transferred from the rotary feeder with increasing inaccuracy to the places for receiving the hose pieces. This disadvantage of high or greatly changed production speed has hitherto been met, for example, by providing more complex aligners.

Die DE 1 910 733 zeigt eine Bogenanlegevorrichtung, die nicht nach dem Funktionsprinzip des Rotationsanlegers arbeitet. Dennoch ist dieser Anleger antriebstechnisch mit der Welle des Hauptantriebs gekoppelt. Um nun die nötigen Änderungen auch während des Betriebs der Maschine durchführen zu können, ist zwischen dem Hauptantrieb und dem Bogenanleger eine getriebliche Verbindung vorgesehen, die sich auch während des Betriebs der Maschine einstellen lässt.The DE 1 910 733 shows a sheet feeding device that does not operate on the principle of operation of the rotary feeder. Nevertheless, this feeder is drivingly coupled with the shaft of the main drive. Order now the necessary To be able to make changes during operation of the machine, a geared connection is provided between the main drive and the sheet feeder, which can also be adjusted during operation of the machine.

Die Aufgabe der Erfindung besteht daher darin, die Genauigkeit der Übergabe der Schlauchstücke von dem Rotationsanleger an die Stellen zur Aufnahme der Fördereinrichtung bei unterschiedlichen Geschwindigkeiten zu verbessern.The object of the invention is therefore to improve the accuracy of the transfer of the hose pieces from the rotary feeder to the locations for receiving the conveyor at different speeds.

Die Aufgabe wird gelöst durch eine Bodenlegevorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 und durch ein Verfahren mit den kennzeichnenden Merkmalen des Anspruchs 5.The object is achieved by a Bodenlegevorrichtung with the characterizing features of claim 1 and by a method with the characterizing features of claim 5.

Die Aufgabe wird demnach dadurch gelöst, dass
eine Steuervorrichtung vorgesehen ist, die die Phasenlage der Aufnahmevorrichtungen (6) des Rotors (3) zu den Stellen (19) zur Aufnahme der Schlauchstücke der translatorischen Fördervorrichtungen (14,18) bei Betrieb des Bodenlegers (1) in Abhängigkeit zu der Fördergeschwindigkeit der translatorischen Fördervorrichtungen (14,18) verändert.The problem is solved by the fact that
a control device is provided, the phase position of the receiving devices (6) of the rotor (3) to the points (19) for receiving the pieces of tubing of the translatory conveying devices (14,18) during operation of the bottom layer (1) in dependence on the conveying speed of the translatory Conveyors (14,18) changed.

Mit der Phasenlage ist die Relativposition gemeint, welche die Aufnahmevorrichtungen des Rotors zu den Stellen zur Aufnahme der Schlauchstücke der translatorischen Fördervorrichtungen zu einem Zeitpunkt einnehmen. Bodenleger des Standes der Technik haben bestenfalls die Möglichkeit, diese Phasenlage durch getriebliche Verstellmöglichkeiten an den Drehmomentabzweigen der Königswelle für den Rotationsanleger oder die Fördervorrichtung zu beeinflussen, wenn der Bodenleger sich außer Betrieb befindet. Der Einfluss einer Änderung der Phasenlage auf die Genauigkeit der Übergabe bei wechselnder Bearbeitungsgeschwindigkeit ist hingegen bisher nicht erkannt und daher nicht in der hier vorgestellten Form genutzt worden. Um dieses zu ermöglichen, umfasst die Erfindung
eine Steuervorrichtung, welche den zeitlichen Vorlauf, mit dem die Aufnahmevorrichtungen des Rotors den Übergabepunkt gegenüber den Stellen zur Aufnahme der Schlauchstücke in den Fördervorrichtungen erreichen als Funktion der Geschwindigkeit ändert. In der Regel wird eine Erhöhung des Vorlaufs bei steigender Geschwindigkeit vorteilhaft sein.With the phase position is meant the relative position, which occupy the receiving devices of the rotor to the points for receiving the pieces of hose of the translatory conveying devices at a time. Grounders of the prior art have at best the possibility of influencing this phase position by means of gear adjustment on the torque branches of the vertical shaft for the rotary feeder or the conveyor when the floor conveyor is out of operation. The influence of a change in the phase position on the accuracy of the transfer at changing processing speed, however, has not been recognized and therefore not used in the form presented here. To make this possible, the invention includes
a control device which the time lead, with which the receiving devices of the rotor reach the transfer point opposite to the points for receiving the hose pieces in the conveying devices as a function of Speed changes. In general, an increase in the flow will be advantageous as the speed increases.

Im Folgenden wird der in den Figuren dargestellte Bodenleger 1 in der Reihenfolge der Bearbeitung der Schlauchstücke dargestellt. Über der Rotorscheibe 3 des Rotationsanlegers 4 ist der Schlauchstapel 2 so angeordnet, dass die Schläuche von den Aufnahmevorrichtungen 6 des Rotationsanlegers 4 aufgenommen werden können.
Diese Aufnahmevorrichtungen 6 sind oft als Trommeln 6 ausgeprägt, welche um ihre Achse 24, die der Achse des Rotors 25 parallel ist, rotierbar sind. Die Trommeln 6 sind mit nicht dargestellten Saugvorrichtungen ausgestattet, welche die Schlauchstücke ansaugen und auf diese Weise von dem Schlauchstapel 2 abheben und auf der Umfangsfläche der Trommeln 6 festlegen. Die Trommeln 6 rotieren entgegen dem Drehsinn des Rotors 8 in Richtung des Pfeiles 7, so dass sich die Bewegung der beiden vorgenannten Elemente 3,6 zu bestimmten Zeitpunkten an bestimmten Stellen aufhebt. Diese Stellen sind die Berührungspunkte 9 zwischen der Asteroide 10, welche die Bewegung des Saugers skizziert und dem Umfang 12 der Rotorscheibe 3. An einer dieser Stellen 9 befindet sich ein Übergabepunkt 13, an dem das für kurze Zeit stillstehende Schlauchstück einer Entnahmevorrichtung 14, welche aus einem speziellen Doppelbandförderer besteht, übergeben wird. Dieser Doppelbandförderer ist in Figur 3 noch einmal dargestellt. Er besteht aus den Rollen 15, der großen Rolle 52 sowie den Bändern 16 und 17 und ist lediglich in Figur 1 und 3 dargestellt. Das Band 16 wird von den Walzen 15b geführt. Es definiert zusammen mit dem Band 17 den Transportspalt 33, in welchem die Schlauchstücke in Richtung des Pfeiles 55 transportiert werden. Das Band 17 wird von den Rollen 15a und der großen Rolle 52 geführt. Das Drehmoment wird von dem Antriebszahnrad 35 des Rotationsanlegers 4 auf das Zahnrad 44 und anschließend auf das Zahnrad 43 übertragen. Das Zahnrad 43 hat eine gemeinsame Welle 47 mit der Walze 52 und gibt ihr so Drehmoment weiter. Die Entnahmevorrichtung 14 übernimmt einzelne Schlauchstücke und wirft sie auf ein weiteres Bandsystem, das als Ausrichter 18 dient, aus.
Insbesondere bei einem solchen Ausrichter 18 sind bestimmte Stellen zur Übernahme der Schlauchstücke vorgesehen. Diese Stellen werden durch Anschläge 19 definiert, welche auf einer ersten Gruppe langsamer laufender Bänder 20 angebracht sind. Diese erste Gruppe von Bändern 20 sind die unteren Bänder des als Ausrichter 18 dienenden Doppelbandförderers. Die obere Gruppe von Bändern 21 ist, wie Figur 2 zeigt, leicht schräg zur Transportrichtung y der Schlauchstücke und den ersten Bändern 20 angebracht. Die zweite Gruppe von Bändern 21 bewegt sich bei Betrieb des Bodenlegers schneller als die erste und bewegt auf diese Weise die Schlauchstücke gegen die Anschläge 19 und das seitliche Anschlagsband 22 und bringt die Schlauchstücke auf diese Weise an die für ihre Aufnahme vorgesehenen Stellen. Dieses Band 22 läuft auf den Rollen 23. Das Anschlagsband 20 ist ebenfalls nur in Figur 2 dargestellt.In the following, the bottom layer 1 shown in the figures will be shown in the order of processing the pieces of hose. Above the rotor disk 3 of the rotary feeder 4, the hose stack 2 is arranged so that the hoses can be received by the receiving devices 6 of the rotary feeder 4.
These recording devices 6 are often pronounced as drums 6, which are about its axis 24, which is parallel to the axis of the rotor 25, rotatable. The drums 6 are equipped with suction devices, not shown, which suck the hose pieces and in this way lift off from the tube stack 2 and set on the peripheral surface of the drums 6. The drums 6 rotate against the direction of rotation of the rotor 8 in the direction of the arrow 7, so that the movement of the two aforementioned elements 3,6 picks up at certain times at certain points. These points are the points of contact 9 between the asteroid 10, which outlines the movement of the nipple and the circumference 12 of the rotor disk 3. At one of these points 9 there is a transfer point 13, at which the piece of hose, which is stationary for a short time, of a removal device 14, which consists of a special double belt conveyor is passed. This double belt conveyor is in FIG. 3 shown again. It consists of the rollers 15, the large roller 52 and the belts 16 and 17 and is only in FIG. 1 and 3 shown. The belt 16 is guided by the rollers 15b. It defines, together with the belt 17, the transport nip 33, in which the hose pieces are transported in the direction of the arrow 55. The belt 17 is guided by the rollers 15a and the large roller 52. The torque is transmitted from the drive gear 35 of the rotary feeder 4 to the gear 44 and then to the gear 43. The gear 43 has a common shaft 47 with the roller 52 and so gives her torque on. The removal device 14 takes over individual pieces of hose and throws them onto a further belt system which serves as an aligner 18.
In particular, in such an aligner 18 certain places for taking over the hose pieces are provided. These locations are defined by stops 19 mounted on a first group of slow moving belts 20. This first group of bands 20 are the lower bands of the double belt conveyor serving as the aligner 18. The upper group of bands 21 is how FIG. 2 shows, slightly obliquely to the transport direction y of the tube pieces and the first bands 20 attached. The second group of bands 21 move faster than the first during operation of the bottom layer and in this way move the pieces of hose against the stops 19 and the lateral stop band 22 and bring the pieces of tubing in this way to the places provided for their inclusion. This tape 22 runs on the rollers 23. The stop band 20 is also only in FIG. 2 shown.

Wie bereits erwähnt ist der dargestellte Positionierungsvorgang von entscheidender Wichtigkeit für die Qualität der vom Bodenleger hergestellten Schläuche. Er kann auch auf andere als die dargestellte Weise erfolgen. Entscheidend für die vorliegende Erfindung ist jedoch die Phasenlage zwischen den wie auch immer gearteten Aufnahmevorrichtungen des Rotors und den ebenfalls unterschiedlich ausprägbaren Stellen zur Aufnahme der Schlauchstücke in den Fördervorrichtungen.
Beim vorliegenden Ausführungsbeispiel eines Bodenlegers übergibt der Ausrichter 18 die Schlauchstücke an ein weiteres nicht dargestelltes Doppelbandsystem, das die Schlauchstücke durch eine Reihe von Bearbeitungsstationen des Bodenlegers führt. In diesem und den gegebenenfalls folgenden Bandsystemen behalten die Schlauchstücke ihren von dem Ausrichter definierten Abstand und ihre Ausrichtung bei. Die genannten Bandsysteme von der Entnahmevorrichtung 14 über den Ausrichter 18 und die sich anschließenden Transportbandsysteme bilden bei diesem Ausführungsbeispiel die Fördervorrichtung 14, 18 im Sinne der Anmeldung.
Anhand der Figur 2 ist gut zu erkennen, dass die Trommeln 6 zwischen den Rotorscheiben 3 flache Scheiben sind, welche an den Achsen 24 zwischen den Scheiben 3 des Rotors 50 aufgehängt sind. Im vorgestellten Ausführungsbeispiel umfasst der Rotor 50 die Rotorscheiben 3, die Stützrollen 49, die Trommeln 6 und die Achsen 24 und 25. Die Art, in der die Trommeln mit Drehmoment versorgt werden, ist dem Fachmann ebenfalls bekannt, so dass auf die Darstellung weiterer Details von Rotor 50 bzw. Rotationsanleger 4 an dieser Stelle verzichtet werden kann.
Der Rotor 50 ist an Wellen 25 am Maschinengestell aufgehängt, von dem nur die Wände 26 auf beiden Seiten des Rotors 50 dargestellt sind. Das zum Antrieb nötige Drehmoment wird von dem lediglich in Figur 1 dargestellten Motor 27 über die Scheibe 28 und den Riemen 29 auf die Scheibe 30 übertragen. Diese Scheibe ist über die Welle 31, dem ersten Winkelgetriebe 51, dem Differential 32 und der Welle 33, welche das Maschinengestell 26 durchgreift, mit dem Zahnrad 34 verbunden. Dieses Zahnrad überträgt das ihm übermittelte Drehmoment auf das Antriebszahnrad des Rotationsanlegers 35, welches über die Welle 25, welche ebenfalls das Maschinengestell 26 durchgreift und das für die Drehung der Rotorscheiben 3 und der Trommeln 6 bestimmte Drehmoment in den Rotationsanleger 4 überträgt.
Das von dem Motor 27 erzeugte und in der beschriebenen Weise auf die Welle 31 übertragene Drehmoment dient auch zum Antrieb weiterer Teile des Bodenlegers. Der Motor ruht auf dem Podest 60.
Über das bereits erwähnte Winkelgetriebe 51 und das zweite Winkelgetriebe 36 erhalten die Kardanwellen 37 und 38 Drehmoment. Das mit der Kardanwelle 38 übertragene Drehmoment dient ausschließlich zum Antrieb nicht dargestellter Komponenten des Bodenlegers 1.
Von der Kardanwelle 38 wird durch das dritte Winkelgetriebe 39 Drehmoment zum Betrieb des Ausrichters 18 abgezweigt. Dieses Drehmoment wird durch nicht näher zu beschreibende getriebliche Mittel 40 auf die Rolle 23a sowie die Achsen 41 und 42 übertragen. Die Rolle 23a treibt das seitliche Anschlagsband 22, die Achse 41 die erste Gruppe von Bändern 20 und die Achse 42 die zweite Gruppe von Bändern 21 an.
Aus den Figuren und der dargestellten Drehmomentübertragung wird deutlich, dass die erfindungsgemäße Veränderung der Phasenlage zwischen den Aufnahmevorrichtungen 6 des Rotationsanlegers 4 und den Stellen der Fördervorrichtung während des Betriebes über das Differential 32 erfolgt. Die Verstellung kann manuell vonstatten gehen, jedoch ist es auch möglich, die entsprechende Stellvorrichtung des Differentials mit einem Stellglied zu verbinden, welches automatisch von einer Steuervorrichtung betätigbar ist. Solche Steuervorrichtungen können die Steuerung aufgrund empirischer Werte (Kalibriertabelle) oder eines funktionalen Zusammenhangs zwischen Phasenverschiebung und Fördergeschwindigkeit vornehmen.
Mit Blick auf die beschriebenen Zeichnungen sind lediglich noch die Stützen 45 und 46, welche im wesentlichen den Ausrichter 18 tragen sowie der Tritt 48 zu erwähnen. Aus darstellerischen Gründen wurde auf das Zeigen der Schlauchstücke verzichtet.As already mentioned, the illustrated positioning operation is of crucial importance to the quality of the tubing produced by the floor layer. It can also be done in ways other than those shown. Decisive for the However, the present invention is the phase angle between the whatever recording devices of the rotor and the also differently expressible locations for receiving the hose pieces in the conveyors.
In the present embodiment of a bottom layer, the aligner 18 transfers the pieces of tubing to another unillustrated double belt system which guides the lengths of tubing through a series of work stations of the bottom layer. In this and any subsequent belt systems, the lengths of tubing retain their spacing and orientation as defined by the organizer. The band systems mentioned by the removal device 14 via the aligner 18 and the subsequent conveyor belt systems form in this embodiment, the conveyor device 14, 18 in the sense of the application.
Based on FIG. 2 It can be clearly seen that the drums 6 between the rotor disks 3 are flat disks which are suspended on the axles 24 between the disks 3 of the rotor 50. In the illustrated embodiment, the rotor 50 comprises the rotor disks 3, the support rollers 49, the drums 6 and the axles 24 and 25. The manner in which the drums are supplied with torque is also known to those skilled in the art, so that the illustration of further details Rotor 50 or rotary feeder 4 can be dispensed with at this point.
The rotor 50 is suspended on shafts 25 on the machine frame, of which only the walls 26 are shown on both sides of the rotor 50. The torque required for the drive is of only in FIG. 1 engine 27 transmitted via the disc 28 and the belt 29 to the disc 30. This disc is connected via the shaft 31, the first angle gear 51, the differential 32 and the shaft 33, which passes through the machine frame 26, with the gear 34. This gear transmits the transmitted torque to the drive gear of the rotary feeder 35, which transmits via the shaft 25, which also passes through the machine frame 26 and transmits the certain for the rotation of the rotor disks 3 and the drums 6 torque in the rotary feeder 4.
The torque generated by the motor 27 and transmitted in the manner described to the shaft 31 also serves to drive other parts of the bottom layer. The engine rests on the pedestal 60.
About the already mentioned bevel gear 51 and the second angle gear 36 receive the propeller shafts 37 and 38 torque. That with the cardan shaft 38 transmitted torque is used exclusively for driving not shown components of the bottom layer. 1
From the propeller shaft 38 is branched off by the third angular gear 39 torque to operate the aligner 18. This torque is transmitted to the roller 23a and the axles 41 and 42 by gear means 40, not further described. The roller 23a drives the lateral stop belt 22, the axle 41 drives the first group of belts 20 and the axle 42 drives the second group of belts 21.
From the figures and the torque transmission shown, it is clear that the change in the phase angle according to the invention between the receiving devices 6 of the rotary feeder 4 and the locations of the conveying device takes place during operation via the differential 32. The adjustment can be done manually, but it is also possible to connect the corresponding adjusting device of the differential with an actuator, which is automatically actuated by a control device. Such control devices may perform control based on empirical values (calibration table) or a functional relationship between phase shift and conveying speed.
With regard to the drawings described are only the supports 45 and 46, which essentially carry the aligner 18 and the step 48 to mention. For illustrative reasons has been dispensed with showing the hose pieces.
