  • the conveyor system thus achieves a largely uniform conveying movement.
  • the rotary damper (71) Due to the large diameter of the rotatable part (104) of the rotary damper (71), it has a large circumference. There are only a few winding layers of the spiral spring (51) along the stroke of the goods pusher (30). The rotary damper (71) with the partially wound spiral spring (51) thus has a largely constant damping behavior along the stroke of the goods pusher (30). The ratio between the tensile force of the spiral spring (51) and the counteracting circumferential force of the rotary damper (71) is thus at least approximately constant over the stroke of the goods pusher (30).
  • the goods experience only a slight acceleration during conveyance.
  • the goods therefore have a low mass inertia, so that the counterforce against the resulting feed force is essentially caused by overcoming the static friction.
  • the goods are shifted slowly and without impact in the conveying direction (11) after a goods have been removed.

Aus der DE 20 2013 101 724 U1 ist ein derartiges Fördersystem bekannt. Hierbei wird die Antriebsvorrichtung über ihre Länge ungleichmäßig belastet. Dies kann einen erhöhten Verschleiß bewirken.From the DE 20 2013 101 724 U1 such a conveyor system is known. Here, the drive device is loaded unevenly over its length. This can cause increased wear.

Aus der GB 2 392 667 A ist aus einem ersten Ausführungsbeispiel eine Fördervorrichtung bekannt, bei der ein Warenschieber mittels einer im Warenschieber gelagerten Spiralfeder entlang einer Führungsbahn verfahrbar ist. Parallel dazu ist an einer separaten Welle im Warenschieber ein Rotationsdämpfer angeordnet, der mittels zweier mit der Führungsbahn kämmenden Zahnräder die Bewegung des Warenschiebers dämpfen soll. Ein zweites Ausführungsbeispiel dieser Druckschrift offenbart einen Führungsschieber, bei dem eine im Warenschieber gelagerte Spiralfeder mit ihrem zweiten Ende um eine Dämpferwelle gewickelt ist. Auf der Dämpferwelle ist ein Zahnrad befestigt, das an der Führungsbahn abwälzt.From the GB 2 392 667 A a conveying device is known from a first exemplary embodiment in which a goods pusher can be moved along a guide track by means of a spiral spring mounted in the goods pusher. In parallel, a rotary damper is arranged on a separate shaft in the goods pusher, which is intended to dampen the movement of the goods pusher by means of two gear wheels meshing with the guide track. A second embodiment of this document discloses a guide slide in which a spiral spring mounted in the goods slide is wound with its second end around a damper shaft. A toothed wheel is attached to the damper shaft and rolls along the guideway.

Aus der DE 10 2013 102 529 U1 ist eine Vorrichtung zum Vorschub von Waren bekannt. In einer Ausführungsform kämmt ein Dämpfungsritzel eines Rotationsdämpfers mit einer Zahnstange. Nach einer anderen Ausführungsform kann ein Rotationsdämpfer an einer drehbaren Achse einer Rollenfeder angeordnet sein.From the DE 10 2013 102 529 U1 a device for advancing goods is known. In one embodiment, a damping pinion of a rotary damper meshes with a toothed rack. According to another embodiment, a rotary damper can be arranged on a rotatable axis of a roller spring.

Der vorliegenden Erfindung liegt daher die Problemstellung zugrunde, ein Fördersystem für Waren zu entwickeln, das die gleichzeitige Entnahme mehrerer Waren erschwert und die Gefahr einer Verletzung minimiert.The present invention is therefore based on the problem of developing a conveyor system for goods that makes it difficult to remove several goods at the same time and minimizes the risk of injury.

Diese Problemstellung wird mit den Merkmalen des Hauptanspruches gelöst. Dazu ist die gesamte Antriebsvorrichtung in Reihe mit der entgegen der Förderrichtung wirkenden Dämpfungsvorrichtung angeordnet. Die Antriebsvorrichtung und die Dämpfungsvorrichtung bilden eine in ein Gehäuse des Warenschiebers einsetzbare vormontierte Einheit. Ein Ende der Spiralfeder ist in einem Frontanker an der Trag- und Führungsschiene befestigt ist.

Die Figuren 1 - 4 zeigen ein Fördersystem (10) für Waren. Derartige Fördersysteme (10) werden beispielsweise in Verkaufsmärkten eingesetzt, um Waren für Kunden zu präsentieren. Hierfür sind die einzelnen Waren im Fördersystem (10) in einer Reihe angeordnet, sodass der Kunde die jeweils erste dargebotene Ware entnehmen kann. Sobald die Ware entnommen ist, fördert das Fördersystem (10) die restlichen Waren nach vorne, so dass die in der Reihe nächstfolgende Ware dem Kunden dargeboten wird.the Figures 1 - 4 show a conveyor system (10) for goods. Such conveyor systems (10) are used, for example, in sales markets to present goods to customers. For this purpose, the individual goods are arranged in a row in the conveyor system (10) so that the customer can remove the first goods presented. As soon as the goods have been removed, the conveyor system (10) conveys the remaining goods to the front so that the next goods in the row are presented to the customer.

Das Fördersystem (10) ist hierfür z.B. in einem Regal angeordnet. Die Förderrichtung (11) kann im Raum waagerecht, schräg oder senkrecht orientiert sein.For this purpose, the conveyor system (10) is arranged, for example, on a shelf. The conveying direction (11) can be oriented horizontally, obliquely or vertically in space.

Das in den Figuren 1 - 4 dargestellte Fördersystem (10) umfasst eine Trag- und Führungsschiene (20) und einen Warenschieber (30). Die Trag- und Führungsschiene (20) ist eine zumindest annähernd U-förmige Schiene, deren obere Randbereiche (21) nach innen gerichtet sind. Die nach oben gerichtete Seiten der Randbereiche (21) bilden Trag- und Gleitflächen (22). Auf diesen Flächen (22) kann die dargebotene Ware aufliegen. Beim Fördern der Waren werden die Waren dann entlang dieser Trag- und Gleitflächen (22) in der parallel zur Längsrichtung der Trag- und Führungsschiene (20) orientierten Förderrichtung (11) in der Darstellung der Figur 1 zum vorderen Ende (12) des Fördersystems (10) hin verschoben.That in the Figures 1 - 4 The conveyor system (10) shown comprises a support and guide rail (20) and a goods pusher (30). The support and guide rail (20) is an at least approximately U-shaped rail, the upper edge regions (21) of which are directed inward. The upwardly directed sides of the edge areas (21) form support and sliding surfaces (22). The presented goods can rest on these surfaces (22). When conveying the goods, the goods are then moved along these support and sliding surfaces (22) in the conveying direction (11) oriented parallel to the longitudinal direction of the support and guide rail (20) in the illustration of Figure 1 moved to the front end (12) of the conveyor system (10).

Die Ebene der Trag- und Gleitflächen (22) begrenzt zusammen mit der Trag- und Führungsschiene (20) einen Führungsraum (23). In diesem zumindest annähernd quaderförmig ausgebildeten Raum (23) ist der Warenschieber (30) geführt. Der Warenschieber (30) hat hierfür Führungsleisten (31), die die Randbereiche (21) der Trag- und Führungsschiene (20) untergreifen. Das Fördersystem (10) kann auch ohne Trag- und Führungsschiene (20) ausgebildet sein.The plane of the support and slide surfaces (22) together with the support and guide rail (20) delimits a guide space (23). The goods pusher (30) is guided in this space (23), which is at least approximately cuboid. The goods pusher (30) has guide strips (31) for this purpose, which engage under the edge areas (21) of the support and guide rail (20). The conveyor system (10) can also be designed without a support and guide rail (20).

Der Warenschieber (30) umfasst ein in die Förderrichtung (11) zeigendes Schubschild (32), an dessen Rückseite (33) ein Gehäuse (34) angeordnet ist. Das z.B. plattenförmig ausgebildete Schubschild (32) hat eine konstante Dicke und ist beispielsweise um einen Winkel von 2 Grad zu einer Normalenebene der Förderrichtung (11) geneigt. Hierbei zeigt das untere Ende (35) des Schubschilds (32) weiter in die Förderrichtung (11) als das obere Ende (36).The goods pusher (30) comprises a pusher plate (32) pointing in the conveying direction (11) and on the rear side (33) of which a housing (34) is arranged. The pusher shield (32), for example designed in the form of a plate, has a constant thickness and is inclined, for example, at an angle of 2 degrees to a normal plane of the conveying direction (11). The lower end (35) of the pusher shield (32) points further in the conveying direction (11) than the upper end (36).

Die den Waren zugewandte Schubfläche (37) des Schubschilds (32) ist im gezeigten Ausführungsbeispiel um 30 % breiter als die Trag- und Führungsschiene (20). Die Höhe der Schubfläche (37) ist in diesen Darstellungen um 40 % größer als ihre Breite. Die kleinsten Abmessungen des Schubschilds (32) entsprechen den Querschnittsabmessungen des Schiebergehäuses (34).The pushing surface (37) of the pushing shield (32) facing the goods is, in the exemplary embodiment shown, 30% wider than the support and guide rail (20). The high of In these representations, the thrust surface (37) is 40% larger than its width. The smallest dimensions of the slide shield (32) correspond to the cross-sectional dimensions of the slide valve housing (34).

An der der Schubfläche (37) abgewandten Seite ist an das Schubschild (32) das Gehäuse (34) angeformt. Dieses ist zumindest annähernd quaderförmig aufgebaut und hat einen seitlichen Ansatz (38). In der in der Figur 2 dargestellten Rückansicht ist dieser Ansatz (38) auf der rechten Seite angeordnet. Oberhalb und unterhalb dieses Aufnahmeansatzes (38) ist im Innenraum (39) des Gehäuses ein Anlageabschnitt (41) angeordnet. Das Gehäuse (34) kann auch einen zumindest annähernd zylindrischen, einen ovalen Querschnitt etc. aufweisen. Auch Mischformen sind denkbar.On the side facing away from the thrust surface (37), the housing (34) is molded onto the thrust shield (32). This is at least approximately cuboid and has a lateral extension (38). In the in the Figure 2 This approach (38) is arranged on the right-hand side shown in the rear view. A contact section (41) is arranged above and below this receiving shoulder (38) in the interior (39) of the housing. The housing (34) can also have an at least approximately cylindrical, oval cross-section, etc. Mixed forms are also conceivable.

Auf der gegenüberliegenden Innenwandseite (42) des Gehäuses (34), vgl. Figur 5, ist eine Aufnahmeeinsenkung (43) ausgebildet. Die Länge dieser nutartig ausgebildeten Aufnahmeeinsenkung (43) beträgt beispielsweise die Hälfte der Länge des Gehäuses (34). In den Darstellungen der Figuren 2, 4 und 5 ist sie auf halber Höhe des Gehäuses (34) angeordnet.On the opposite inner wall side (42) of the housing (34), see. Figure 5 , a receiving recess (43) is formed. The length of this groove-like receiving recess (43) is, for example, half the length of the housing (34). In the representations of the Figures 2 , 4 and 5 it is arranged halfway up the housing (34).

Unterhalb des Schubschilds (32) ist im Warenschieber (30) ein Durchführschlitz (44) ausgebildet. Bei einem in die Trag- und Führungsschiene (20) eingesetzten Warenschieber (30) liegt dieser Durchführschlitz (44) im Führungsraum (23) der Trag- und Führungsschiene (20). Der Durchführschlitz (44) hat eine rechteckige Querschnittsfläche. Seine Breite beträgt beispielsweise 60 % des Abstandes zwischen den Randbereichen (21) und seine Höhe z.B. 10 % dieses Abstands. Oberhalb des Durchführschlitzes (44) sind an der Unterseite des Schubschilds (32) Führungsflächenabschnitte (45, 46) ausgebildet. Diese umfassen in den dargestellten Ausführungsbeispielen einen an den Durchführschlitz (44) angrenzenden waagerechten Führungsflächenabschnitt (45) und einen an diesen angrenzenden, zum Innenraum (39) des Gehäuses (34) hin orientierten Abschnitt (46), der z.B. um einen Winkel von 30 Grad zu erstgenannten Abschnitt (45) geneigt ist.A slot (44) is formed in the product pusher (30) below the push plate (32). In the case of a goods slide (30) inserted into the support and guide rail (20), this feed-through slot (44) is located in the guide space (23) of the support and guide rail (20). The through slot (44) has a rectangular cross-sectional area. Its width is, for example, 60% of the distance between the edge regions (21) and its height, for example, 10% of this distance. Above the feed-through slot (44), guide surface sections (45, 46) are formed on the underside of the thrust shield (32). These include in the illustrated embodiments a horizontal guide surface section (45) adjoining the feed-through slot (44) and a section (46) adjoining this, oriented towards the interior (39) of the housing (34), which is, for example, at an angle of 30 degrees to the first-mentioned section (45) is inclined.

Im Innenraum (39) des Gehäuses (34) sind Verstärkungsrippen (47) angeordnet. Diese befinden sich am Schubschild (32) sowie an den Seitenwänden (42, 48). Die schmalen Rippen (47) führen zu geringen Reibwiderständen für im Gehäuse (34) bewegte Bauteile.Reinforcing ribs (47) are arranged in the interior (39) of the housing (34). These are located on the pusher plate (32) and on the side walls (42, 48). The narrow ribs (47) lead to low frictional resistance for components moving in the housing (34).

Das Fördersystem (10) umfasst eine Antriebsvorrichtung (50). Diese umfasst z.B. ein elastisch verformbares Element (51), das den Warenschieber (30) in der Förderrichtung (11) antreibt. Im Ausführungsbeispiel ist das elastisch verformbare Element (51) als Spiralfeder (51) mit rechteckigem Querschnitt, z.B. als Rollenfeder (51), ausgebildet. Diese ist beispielsweise im Warenschieber (30) und an der Trag- und Führungsschiene (20) befestigt.The conveyor system (10) comprises a drive device (50). This includes, for example, an elastically deformable element (51) which drives the goods pusher (30) in the conveying direction (11). In the exemplary embodiment, the elastically deformable element (51) is designed as a spiral spring (51) with a rectangular cross-section, e.g. as a roller spring (51). This is attached, for example, in the goods pusher (30) and on the support and guide rail (20).

An der Trag- und Führungsschiene (20) ist die Spiralfeder (51) an einem Frontanker (80) befestigt. Dieser Frontanker (80) ist in der Figur 7 als Einzelteil dargestellt. Er hat einen u-förmig ausgebildeten Tragrahmen (81), mit dem er z.B. auf dem Regal aufliegt. Zwei seitlich angeordnete Abstützbalken (82) verhindern ein Verkippen. Im mittleren Bereich hat der Frontanker (80) Führungsleisten (83). Mittels dieser Führungsleisten (83) ist der Frontanker (80) an der Trag- und Führungsschiene (20) z.B. kraftschlüssig befestigt, vgl. Figur 1. Es ist auch denkbar, den Frontanker (80) mittels zusätzlicher Befestigungselemente an der Trag- und Führungsschiene (20) zu befestigen. Auch eine Befestigung des Frontankers (80) direkt am Regal ist denkbar.The spiral spring (51) is attached to a front anchor (80) on the support and guide rail (20). This front anchor (80) is in the Figure 7 shown as a single part. It has a U-shaped support frame (81) with which it rests on the shelf, for example. Two laterally arranged support beams (82) prevent tilting. The front anchor (80) has guide strips (83) in the middle area. By means of these guide strips (83), the front anchor (80) is fastened to the support and guide rail (20), for example in a non-positive manner, cf. Figure 1 . It is also conceivable to fasten the front anchor (80) to the support and guide rail (20) by means of additional fastening elements. Attaching the front anchor (80) directly to the shelf is also conceivable.

Die über die Trag- und Gleitflächen (22) herausstehenden Abschnitte des Frontankers (80) sind keilförmig ausgebildet. Mittels dieser Keilflächen (84, 85) kann beispielsweise die erste Ware erhöht dem Kunden dargeboten werden.The sections of the front anchor (80) protruding beyond the support and sliding surfaces (22) are wedge-shaped. By means of these wedge surfaces (84, 85), for example, the first item can be presented to the customer in an increased manner.

Die Spiralfeder (51) ist in einen Führungsschlitz (86) des Frontankers (80) einschiebbar. Dieser Führungsschlitz (86) liegt in der Darstellung der Figur 1 im Führungsraum (23) der Trag- und Führungsschiene (20). Die Spiralfeder (51) hat an ihrem freien Ende beispielsweise einen Durchbruch. Durch diesen Durchbruch hindurch ist die Spiralfeder (51) dann mittels eines in eine Befestigungsbohrung (87) des Frontankers (80) eingesetzten Stiftes, einer Schraube, etc. oder eines frontankerseitigen Zapfens befestigbar.The spiral spring (51) can be pushed into a guide slot (86) in the front anchor (80). This guide slot (86) is in the illustration of Figure 1 in the guide space (23) of the support and guide rail (20). The spiral spring (51) has, for example, an opening at its free end. The spiral spring (51) can then be fastened through this opening by means of a pin inserted into a fastening hole (87) of the front anchor (80), a screw, etc. or a pin on the front anchor.

Im Warenschieber (30) ist die als Zugfeder ausgebildete Spiralfeder (51) an der drehbaren Nabe (52) einer Federhülse (53) z.B. kraftschlüssig befestigt. Die Federhülse (53) ist im Innenraum (39) des Gehäuses (34) angeordnet. Mittels eines Zapfens (54) sitzt die Federhülse (53) z.B. verdrehsicher in der Aufnahmeeinsenkung (43) des Gehäuses (30). Die Nabe (52) und der Zapfen (54) der Federhülse (53) können auch starr miteinander verbunden sein. Die Feder (51) ist in der Darstellung der Figur 3 an der dem Schubschild (32) abgewandten Seite der Federhülse (53) aus dieser herausgeführt. Die Spiralfeder (51) liegt im Ausführungsbeispiel am Führungsflächenabschnitt (45) an und ist durch den Durchführungsschlitz (44) hindurchgeführt.In the goods pusher (30), the spiral spring (51) designed as a tension spring is attached to the rotatable hub (52) of a spring sleeve (53), for example in a non-positive manner. The spring sleeve (53) is arranged in the interior (39) of the housing (34). By means of a pin (54), the spring sleeve (53) sits, for example, in a non-rotating manner in the receiving recess (43) of the housing (30). The hub (52) and the pin (54) of the spring sleeve (53) can also be rigidly connected to one another. The spring (51) is shown in the Figure 3 led out of the spring sleeve (53) on the side of the spring sleeve (53) facing away from the thrust shield (32). In the exemplary embodiment, the spiral spring (51) rests on the guide surface section (45) and is passed through the feed-through slot (44).

Die Federhülse (53) sitzt auf einer Dämpfungs- und/oder Verzögerungsvorrichtung (70). Erfindungsgemäß umfasst die Dämpfungsvorrichtung (70) einen Rotationsdämpfer (71), der beispielsweise mit hydraulischem Fluid befüllt ist, vgl. Figur 6. Das hydraulische Fluid ist beispielsweise ein Silikonöl. Der Rotationsdämpfer (71) ist in der Darstellung der Figur 3 in das Gehäuse (34) derart eingesetzt, dass seine Befestigungsflansche (72) im Innenraum (39) des Gehäuses (34) am oberen und unteren Anlageabschnitt (41) anliegen. Sie verhindern so ein Verdrehen des Rotationsdämpfers (71) in der Darstellung der Figur 3 entgegen dem Uhrzeigersinn. Gegebenenfalls kann - bei einem Gehäuse (34) mit abnehmbarer Seitenwand - der Rotationsdämpfer (71) mittels zweier Schrauben an den Befestigungsabschnitten (41) des Gehäuses (34) befestigt werden. Die zentrale, aus dem Dämpfergehäuse (73) herausstehende Dämpferwelle (74) ragt in die Federhülse (53). Die Dämpferwelle (74) ist mit der Nabe (52) der Federhülse (53) kraft-, form- und/oder stoffschlüssig verbunden. Im Ausführungsbeispiel ist die Nabe (52) auf die Dämpferwelle (74) aufgepresst. Der eingesetzte Rotationsdämpfer (71) kann die Drehung seiner Dämpferwelle (74) dämpfen, wenn diese in der Darstellung der Figur 3 entgegen dem Uhrzeigersinn gedreht wird. Es ist aber auch denkbar, einen Rotationsdämpfer (71) einzusetzen, der in beide Drehrichtungen der Dämpferwelle (74) deren Rotationsbewegung dämpft.The spring sleeve (53) sits on a damping and / or delay device (70). According to the invention, the damping device (70) comprises a rotary damper (71) which is filled, for example, with hydraulic fluid, cf. Figure 6 . The hydraulic fluid is, for example, a silicone oil. The rotary damper (71) is shown in FIG Figure 3 inserted into the housing (34) in such a way that its fastening flanges (72) in the interior (39) of the housing (34) rest against the upper and lower contact section (41). In this way you prevent the rotary damper (71) from rotating in the illustration in FIG Figure 3 counter clockwise. If necessary, in the case of a housing (34) with a removable side wall, the rotary damper (71) can be fastened to the fastening sections (41) of the housing (34) by means of two screws. The central damper shaft (74) protruding from the damper housing (73) protrudes into the spring sleeve (53). The damper shaft (74) is connected to the hub (52) of the spring sleeve (53) with a force fit, form fit and / or material fit. In the exemplary embodiment, the hub (52) is pressed onto the damper shaft (74). The rotary damper (71) used can dampen the rotation of its damper shaft (74) if this is shown in the illustration of Figure 3 counterclockwise. However, it is also conceivable to use a rotary damper (71) which dampens the rotational movement of the damper shaft (74) in both directions of rotation.

Bei der Montage des Fördersystems (10) wird beispielsweise die vormontierte Einheit aus der Antriebsvorrichtung (50) und der Dämpfungsvorrichtung (70) in das Gehäuse (34) eingesetzt. Der Rotationsdämpfer (71) sitzt hierbei im Gehäuseansatz (38) und der Zapfen (54) der Federhülse (53) in der Aufnahmeeinsenkung (43). Der untere Befestigungsflansch (72) des Rotationsdämpfers (71) zeigt in die Richtung des Schubschilds (32). Die Einheit kann lose im Gehäuse (34) sitzen oder in den Innenraum (39) des Gehäuses (34) eingeklemmt sein. Die Antriebsvorrichtung (50) und die Dämpfungsvorrichtung (70) sind hierbei in Reihe angeordnet. Die Rollenfeder (51) wird durch den Durchführungsschlitz (44) hindurch aus dem Warenschieber (30) herausgeführt. Gegebenenfalls kann das Gehäuse des Warenschiebers (30) nun verschlossen werden. Der Warenschieber (30) wird in die Trag- und Führungsschiene (20) eingesetzt und der Frontanker (80) wird am vorderen Ende (24) der Trag- und Führungsschiene (20) montiert. Das freie Ende der Rollenfeder (51) kann nun im Frontanker (80) befestigt werden.When assembling the conveyor system (10), for example, the preassembled unit consisting of the drive device (50) and the damping device (70) is inserted into the housing (34). The rotary damper (71) is seated in the housing extension (38) and the pin (54) of the spring sleeve (53) is seated in the recess (43). The lower mounting flange (72) of the rotary damper (71) points in the direction of the thrust shield (32). The unit can sit loosely in the housing (34) or be clamped in the interior (39) of the housing (34). The drive device (50) and the damping device (70) are arranged in series. The roller spring (51) is led out of the goods pusher (30) through the feed-through slot (44). If necessary, the housing of the goods slide (30) can now be closed. The goods pusher (30) is inserted into the support and guide rail (20) and the front anchor (80) is mounted on the front end (24) of the support and guide rail (20). The free end of the roller spring (51) can now be attached to the front anchor (80).

Nach dem Einbau in ein Regal verfügt das Fördersystem (10) bespielsweise über einen im Bereich des vorderen Endes (24) der Trag- und Führungsschiene (20) angeordneten, hier nicht dargestellten Frontanschlag, an dem die Waren anliegen. Um die Waren einzusetzen, wird der Warenschieber (30) nach hinten gezogen. Die Feder (51) wird gespannt. Nun können die Waren in den Bereich zwischen dem Schubschild (32) und dem Frontanschlag plaziert werden. Die Waren können hierbei auf den Trag- und Gleitflächen (22) der Trag- und Führungsschiene (20) aufliegen. Es ist aber auch denkbar, die Waren auf separate Schienen aufzulegen, die parallel zur Trag- und Führungsschiene (20) außerhalb des Warenschiebers (30) angeordnet sind. Hiermit können beispielsweise breite Waren mittels des Fördersystems (10) zur Entnahmeposition am Frontanschlag (80) gefördert werden. Gegebenenfalls können die auf dem Fördersystem (10) angeordneten Waren bis auf die erste Ware zusätzlich abgedeckt sein. Hiermit kann verhindert werden, dass Waren entnommen werden, die noch nicht in der Entnahmeposition stehen.After installation in a shelf, the conveyor system (10) has, for example, a front stop, not shown here, which is arranged in the area of the front end (24) of the support and guide rail (20) and against which the goods rest. To insert the goods, the goods pusher (30) is pulled back. The spring (51) is tensioned. The goods can now be placed in the area between the push plate (32) and the front stop. The goods can rest on the support and sliding surfaces (22) of the support and guide rail (20). However, it is also conceivable to place the goods on separate rails which are arranged parallel to the support and guide rail (20) outside the goods pusher (30). In this way, for example, wide goods can be conveyed to the removal position on the front stop (80) by means of the conveyor system (10). If necessary, the goods arranged on the conveyor system (10) can additionally be covered, with the exception of the first goods. This can prevent goods from being removed that are not yet in the removal position.

Sobald eine Ware entnommen ist, schiebt der Warenschieber (30) unter der Vorspannung der Feder (51) die verbliebenen Waren in der Förderrichtung (11) nach vorne, bis die nächste Ware in der Entnahmeposition liegt. Diese Bewegung wird mittels des Rotationsdämpfers (71) verzögert. Die Waren werden langsam und schlagfrei in der Förderrichtung (11) verschoben. Das hierbei verstreichende Zeitintervall verhindert, dass zwei Waren unmittelbar hintereinander entnommen werden können. Ist eine Ware einmal entnommen, kann sie vom Kunden nicht wieder in das Fördersystem (10) eingesetzt werden, da nach der Entnahme bereits die nächste Ware in die Förderrichtung (11) gefördert wird oder sich in der Entnahmeposition befindet. Aufgrund der langsamen Fördergeschwindigkeit besteht keine Verletzungsgefahr des Kunden.As soon as a product has been removed, the product pusher (30) pushes the remaining goods forwards in the conveying direction (11) under the bias of the spring (51) until the next product is in the removal position. This movement is delayed by means of the rotary damper (71). The goods are slow and Shifted without jolts in the conveying direction (11). The time interval that elapses in this case prevents two goods from being removed immediately one after the other. Once a product has been removed, it cannot be reinserted into the conveyor system (10) by the customer, since after removal the next product is already being conveyed in the conveying direction (11) or is in the removal position. Due to the slow conveyor speed, there is no risk of injury to the customer.

Während des Betriebs wird die Feder (51) entlang ihrer gesamten Länge gleichmäßig auf Zug beansprucht. Auch der Rotationsdämpfer (91) ist gleichmäßig belastet. Somit entstehen entlang des Kraftflusses vom Frontanker (80) über die Antriebsvorrichtung (50) und die Dämpfungsvorrichtung (70) zum Warenschieber (30) keine Spannungsspitzen, die zu einem erhöhten Verschleiß führen könnten.During operation, the spring (51) is subjected to even tensile stress along its entire length. The rotary damper (91) is also evenly loaded. Thus, along the power flow from the front anchor (80) via the drive device (50) and the damping device (70) to the goods pusher (30), there are no stress peaks that could lead to increased wear.

Die Vorschubkraft und die Vorschubgeschwindigkeit des Warenschiebers (30) können einstellbar sein. So kann beispielsweise die Vorspannung der Feder (51) einstellbar sein. Auch die Dämpfungsvorrichtung (70) kann beispielsweise mittels Verstellung der Dämpfungsdrossel einstellbar sein. Auch ist es denkbar, die Steifigkeit der Feder (51) z.B. abhängig von der Masse der Ware und ihrer Haftreibung zur Auflagefläche auszuwählen. Auch kann z.B. die Viskosität des Fluids und/oder der Drosselquerschnitt der Dämpfungsvorrichtung (70) warenspezifisch in Abhängigkeit der gewünschten Verzögerung beim Warenvorschub ausgewählt werden. Hierzu kann dann z.B. eine warenspezifische Kombination zwischen Antriebsvorrichtung (50) und Dämpfungsvorrichtung (70) in das Gehäuse (34) eingesetzt werden.The feed force and the feed speed of the goods pusher (30) can be adjustable. For example, the preload of the spring (51) can be adjusted. The damping device (70) can also be adjustable, for example, by adjusting the damping throttle. It is also conceivable to select the stiffness of the spring (51) as a function of the mass of the goods and their static friction with respect to the support surface, for example. For example, the viscosity of the fluid and / or the throttle cross-section of the damping device (70) can also be selected specifically for the goods as a function of the desired delay in the advance of the goods. For this purpose, for example, a product-specific combination between the drive device (50) and the damping device (70) can be inserted into the housing (34).

Der Warenschieber (30) mit der Antriebsvorrichtung (50) und der hiermit kombinierten Dämpfungs- und/oder Verzögerungsvorrichtung (70) ist an ein bestehendes Fördersystem (10) nachrüstbar. So kann ein bestehender Warenschieber mit wenigen Handgriffen gegen den oben beschriebenen Warenschieber (30) ausgetauscht werden. Das Fördersystem (10) ist zudem wartungsfreundlich, da die Montage und Demontage aller Komponenten weitgehend werkzeuglos erfolgen kann.The goods pusher (30) with the drive device (50) and the damping and / or delaying device (70) combined therewith can be retrofitted to an existing conveyor system (10). In this way, an existing goods pusher can be exchanged for the goods pusher (30) described above in just a few simple steps. The conveyor system (10) is also maintenance-friendly, since all components can be assembled and disassembled largely without tools.

Das Fördersystem (10) ist für unterschiedliche Längen der Trag- und Führungsschiene (20) einsetzbar. Wird eine gegenüber der ursprünglichen Auslegung kürzere oder eine längere Trag- und Führungsschiene (20) eingesetzt, kann die Antriebsvorrichtung (50) und/oder die Dämpfungs- und/oder Verzögerungsvorrichtung (70) entsprechend angepasst werden.The conveyor system (10) can be used for different lengths of the support and guide rails (20). If a support and guide rail (20) that is shorter or longer than the original design is used, the drive device (50) and / or the damping and / or deceleration device (70) can be adapted accordingly.

Die Antriebsvorrichtung (50) kann auch eine Zug- oder Druckfeder (51) umfassen. Diese ist dann z.B. parallel oder in Reihe mit einer Verzögerungs- oder einer Dämpfungsvorrichtung (70) angeordnet. Die Dämpfungs- oder Verzögerungsvorrichtung (70) kann hierbei hydraulisch oder pneumatisch arbeiten. Bei einer parallelen Anordnung oder bei einer Reihenanordnung kann sowohl die Antriebsvorrichtung (50) als auch die Dämpfungs- und/oder Verzögerungsvorrichtung (70) im Führungsraum (23) der Trag- und Führungsschiene (20) angeordnet sein.The drive device (50) can also comprise a tension or compression spring (51). This is then arranged, for example, in parallel or in series with a delay or a damping device (70). The damping or delaying device (70) can operate hydraulically or pneumatically. In the case of a parallel arrangement or a series arrangement, both the drive device (50) and the damping and / or deceleration device (70) can be arranged in the guide space (23) of the support and guide rail (20).

Die Dämpfungs- und/oder Verzögerungsvorrichtung (70) kann auch auf die Trag- und Führungsschiene (20) wirken. Bei einer derartigen Ausführung besteht beispielsweise keine Verbindung zwischen der Dämpferwelle (74) und der Nabe (52) der Federhülse (53). Die Dämpferwelle (74) wirkt z.B. auf ein Zahnrad, das mit einer im Führungsraum (23) angeordneten Zahnstange kämmt. Wird der Warenschieber (30) nach hinten verschoben, wälzt das Zahnrad auf der Zahnstange ab. Die Feder (51) wird gespannt. Beim Entspannen der Feder (51) wird der Warenschieber (30) nach vorne gezogen. Das Zahnrad wird mittels des Rotationsdämpfers gebremst und bremst damit den Warenschieber (30) ab. Diese Ausführung der Dämpfungsvorrichtung ist beispielsweise auch mit einer schwerkraftgesteuerten Antriebsvorrichtung kombinierbar.The damping and / or delaying device (70) can also act on the support and guide rail (20). In such an embodiment, there is, for example, no connection between the damper shaft (74) and the hub (52) of the spring sleeve (53). The damper shaft (74) acts, for example, on a toothed wheel which meshes with a toothed rack arranged in the guide space (23). If the goods pusher (30) is moved backwards, rolls the gear on the rack. The spring (51) is tensioned. When the spring (51) is released, the goods pusher (30) is pulled forward. The gear wheel is braked by the rotary damper and thus brakes the goods pusher (30). This embodiment of the damping device can, for example, also be combined with a gravity-controlled drive device.

Die Figuren 8 bis 12 zeigen ein weiteres Fördersystem (10) für Waren in Ansichten, Schnitten und in Einzelteilen. Der Aufbau, die Anordnung und die Funktion dieses Fördersystems (10) entsprechen beispielsweise weitgehend dem Aufbau, der Anordnung und der Funktion des in den Figuren 1 - 7 dargestellten Fördersystems (10). Auch mit diesem Fördersystem (10) wird die jeweils zu entnehmende Ware dem Kunden an der gleichen Position präsentiert. Hierfür kann das Fördersystem (10) an oder in einem Regal befestigt sein.the Figures 8 to 12 show a further conveyor system (10) for goods in views, sections and in individual parts. The structure, arrangement and function of this conveyor system (10) largely correspond to the structure, arrangement and function of the in the Figures 1 - 7 illustrated conveyor system (10). With this conveyor system (10), too, the goods to be removed are presented to the customer in the same position. For this purpose, the conveyor system (10) can be attached to or in a shelf.

Das Fördersystem (10) umfasst einen Warenschieber (30), der in den Darstellungen der Figuren 8 und 9 entlang einer Trag- und Führungsschiene (20) geführt ist. Auch dieses Fördersystem (10) kann ohne eine Trag- und Führungsschiene (20) ausgebildet sein. Mittels einer Antriebsvorrichtung (50) ist der Warenschieber (30) von einer ersten Endlage, in der das Fördersystem (10) mit Waren befüllt ist, in eine zweite Endlage, in der sämtliche Waren aus dem Fördersystem (10) entnommen sind, verfahrbar. Die Richtung von der ersten Endlage in die zweite Endlage wird im Folgenden als Förderrichtung (11) bezeichnet.The conveyor system (10) comprises a goods pusher (30), which in the representations of Figures 8 and 9 is guided along a support and guide rail (20). This conveyor system (10) can also be designed without a support and guide rail (20). The goods pusher (30) can be moved by means of a drive device (50) from a first end position in which the conveyor system (10) is filled with goods to a second end position in which all goods have been removed from the conveyor system (10). The direction from the first end position to the second end position is referred to below as the conveying direction (11).

Der Warenschieber (30), vgl. Figur 10, hat ein Gehäuse (34), dessen in die Förderrichtung (11) orientierte Stirnseite mittels eines Schubschilds (32) begrenzt ist. Das Schubschild (32) ist beispielsweise so ausgebildet wie im Zusammenhang mit dem ersten Ausführungsbeispiel beschrieben. Das Schubschild (32) und/oder die der Ware zugewandte Schubseite (93) können auch ein- oder mehrachsig gebogen oder gewölbt ausgebildet sein. Die Schubseite (93) kann z.B. eine konkave oder konvexe Schubfläche (37) aufweisen. Das Schubschild (32) steht in den Darstellungen der Figuren 8 - 10 seitlich und nach oben hin über das Gehäuse (34) über. Das Schubschild (32) kann jedoch auch bündig zum Gehäuse (34) ausgeführt sein. Auch eine asymmetrische Anordnung ist denkbar. Der Warenschieber (30) hat auch in diesem Ausführungsbeispiel zwei parallel zur Förderrichtung (11) orientierte außenliegende Führungsleisten (31).The goods pusher (30), cf. Figure 10 , has a housing (34), the end face of which, oriented in the conveying direction (11), is delimited by means of a thrust shield (32). The push shield (32) is designed, for example, as in the context described with the first embodiment. The push plate (32) and / or the push side (93) facing the goods can also be curved or arched in one or more axes. The push side (93) can, for example, have a concave or convex push surface (37). The thrust shield (32) is in the representations of the Figures 8-10 laterally and upwards over the housing (34). The thrust shield (32) can, however, also be designed to be flush with the housing (34). An asymmetrical arrangement is also conceivable. The goods pusher (30) in this exemplary embodiment also has two external guide strips (31) oriented parallel to the conveying direction (11).

Das Gehäuse (34), vgl. die Figuren 9 und 10, hat einen Innenraum (39), in dem die Antriebsvorrichtung (50) und ein Leitelement (60) angeordnet sind. Die Antriebsvorrichtung (50) und das Leitelement (60) können auch an einer Außenseite des Warenschiebers (30) angeordnet sein.The housing (34), see Figures 9 and 10 , has an interior space (39) in which the drive device (50) and a guide element (60) are arranged. The drive device (50) and the guide element (60) can also be arranged on an outside of the goods pusher (30).

Die Antriebsvorrichtung (50) umfasst auch in diesem Ausführungsbeispiel eine Spiralfeder (51), die mit einem Rotationsdämpfer (71) gekoppelt ist. Die Spiralfeder (51) hat einen rechteckigen Querschnitt und ist als Rollenfeder ausgebildet. Ein freies Ende der Spiralfeder (51) ist im Ausführungsbeispiel an einem Frontanker (80) befestigt, der z.B. an der in der Förderrichtung (11) orientierten Stirnseite der Trag- und Führungsschiene (20) angeordnet ist. Auch die Anordnung dieses freien Endes an einem Regal ist denkbar. Das andere Ende der Spiralfeder (51) ist am Rotationsdämpfer (71) fixiert. Die Spiralfeder (51) hat im Ausführungsbeispiel eine über ihren Hub konstante Federrate. Die Zugkraft beträgt beispielsweise 10 Newton. Die Zugkraft kann zwischen zwei und z.B. 14 Newton betragen. Auch höhere und/oder niedrigere Kräfte sind denkbar. Es ist aber auch denkbar, eine Spiralfeder (51) mit einer progressiven, einer degressiven oder einer abschnittsweise definierten Federrate einzusetzen. Die Dicke der Spiralfeder (51) beträgt im Ausführungsbeispiel 0,2 Millimeter. Sie hat beispielsweise eine Breite von 14 Millimetern.In this exemplary embodiment, too, the drive device (50) comprises a spiral spring (51) which is coupled to a rotary damper (71). The spiral spring (51) has a rectangular cross section and is designed as a roller spring. In the exemplary embodiment, a free end of the spiral spring (51) is attached to a front anchor (80) which is arranged, for example, on the end face of the support and guide rail (20) oriented in the conveying direction (11). The arrangement of this free end on a shelf is also conceivable. The other end of the spiral spring (51) is fixed to the rotary damper (71). In the exemplary embodiment, the spiral spring (51) has a spring rate that is constant over its stroke. The tensile force is, for example, 10 Newtons. The tensile force can be between two and 14 Newtons, for example. Higher and / or lower forces are also conceivable. But it is also conceivable that a Use a spiral spring (51) with a progressive, a degressive or a partially defined spring rate. The thickness of the spiral spring (51) is 0.2 millimeters in the exemplary embodiment. For example, it is 14 millimeters wide.

Der Rotationsdämpfer (71), vgl. Figur 11, hat einen relativ zum Warenschieber (30) feststehenden Teil (103) und einen in Bezug zum feststehenden Teil (103) rotierbaren Teil (104). Im Ausführungsbeispiel umfasst der feststehende Teil (103) ein Dämpfergehäuse (73), das im Gehäuse (34) des Warenschiebers (30) verdrehsicher gelagert ist. Der feststehende Teil (103) kann auch im oder am Warenschieber (30) befestigt sein. Beispielsweise kann er mittels eines Befestigungsflanschs (72) befestigt sein.The rotary damper (71), cf. Figure 11 , has a part (103) which is fixed relative to the goods pusher (30) and a part (104) which is rotatable with respect to the fixed part (103). In the exemplary embodiment, the stationary part (103) comprises a damper housing (73) which is mounted in the housing (34) of the goods pusher (30) so that it cannot rotate. The fixed part (103) can also be fastened in or on the goods slide (30). For example, it can be fastened by means of a fastening flange (72).

Der rotierbare Teil (104) umfasst im Ausführungsbeispiel die Dämpferwelle (74) des Rotationsdämpfers (71) und einen auf ihr sitzenden Befestigungsadapter (76). Der rotierbare Teil (104) kann auch ohne Befestigungsadapter (76) ausgebildet sein. Der Befestigungsadapter (76) kann beispielsweise kraftschlüssig mit der Dämpferwelle (74) verbunden sein, beispielsweise ist er auf diese aufgepresst. Der Außendurchmesser des rotierbaren Teils (104) beträgt beispielsweise 26 Millimeter. Dieser Durchmesser ist größer oder gleich dem Hundertfachen der Dicke der Spiralfeder (51). Es ist auch denkbar, dass der rotierbare Teil (104) das Dämpfergehäuse (73) aufweist und der feststehende Teil (103) die Dämpferwelle (74) umfasst.In the exemplary embodiment, the rotatable part (104) comprises the damper shaft (74) of the rotary damper (71) and a fastening adapter (76) seated on it. The rotatable part (104) can also be designed without a fastening adapter (76). The fastening adapter (76) can, for example, be non-positively connected to the damper shaft (74), for example it is pressed onto it. The outer diameter of the rotatable part (104) is, for example, 26 millimeters. This diameter is greater than or equal to a hundred times the thickness of the spiral spring (51). It is also conceivable that the rotatable part (104) has the damper housing (73) and the stationary part (103) includes the damper shaft (74).

Die Spiralfeder (51) umschlingt zumindest bereichsweise die Mantelfläche (77) des Befestigungsadapters (76). Beispielsweise ist das warenschieberseitige Ende der Spiralfeder (51) am Befestigungsadapter (76) aufgrund der Federspannung festgelegt oder an diesem befestigt. Bei einer Ausführung ohne Befestigungsadapter (76) ist die Spiralfeder (51) z.B. an der Dämpferwelle (74) befestigt. Der Befestigungsadapter (76) weist auf der dem Dämpfergehäuse (73) abgewandten Seite eine Führungsnase (78) auf. Mit dieser ist er beispielsweise in einer Führungsnut (96) des Gehäuses (34) gelagert. Die Spiralfeder (51) ist im Ausführungsbeispiel durch den Durchführschlitz (44) des Warenschiebers (30) hindurchgeführt und berührt - bei vollständig abgewickelter Spiralfeder (51) - in einer Abhebelinie (55) den rotierbaren Teil (104) des Rotationsdämpfers (71). Zwischen dem Durchführschlitz (44) und der Abhebelinie (55) schließt die Spiralfeder (51) mit einer Normalenebene zur Förderrichtung (11) beispielsweise einen Winkel von 70 Grad ein. Die Lage der Abhebelinie (55) ist im Auführungsbeispiel durch eine den Durchführschlitz (44) unter Berührung des Schubschilds (32) durchdringende Gerade bestimmt, die eine Tangente an den rotierbaren Teil (104) bildet.The spiral spring (51) wraps around the jacket surface (77) of the fastening adapter (76) at least in some areas. For example, the end of the spiral spring (51) on the side of the merchandise slide is fixed or fastened to the fastening adapter (76) due to the spring tension. When running without Fastening adapter (76), the spiral spring (51) is fastened, for example, to the damper shaft (74). The fastening adapter (76) has a guide nose (78) on the side facing away from the damper housing (73). With this it is mounted, for example, in a guide groove (96) in the housing (34). In the exemplary embodiment, the spiral spring (51) is passed through the feed-through slot (44) of the goods slide (30) and, when the spiral spring (51) is completely unwound, touches the rotatable part (104) of the rotary damper (71) in a lever line (55). Between the feed-through slot (44) and the lever line (55), the spiral spring (51) forms an angle of, for example, 70 degrees with a plane normal to the conveying direction (11). In the exemplary embodiment, the position of the lever line (55) is determined by a straight line which penetrates the feed-through slot (44) while touching the thrust shield (32) and which forms a tangent to the rotatable part (104).

Der Rotationsdämpfer (71) hat ein beispielsweise konstantes Drehmoment. Im Ausführungsbeispiel beträgt dieses Moment 0,010 Newton mal Meter. Es ist aber auch denkbar, einen Rotationsdämpfer (71) mit einem höheren oder einem niedrigeren Drehmoment einzusetzen. Beispielsweise liegt das Drehmoment zwischen 0,005 und 0,015 Newton mal Meter. An der Fixierung der Spiralfeder (51) beträgt die Umfangskraft des Rotationsdämpfers (71) somit 85 % der Kraft der Spiralfeder (51). Die Umfangskraft des Rotationsdämpfers (71) an dieser Stelle kann zwischen 70 % und 98 % der Federkraft betragen. Bei einer Spiralfeder (51) mit einer über ihre Länge veränderlichen Federkraft bezieht sich das genannte Verhältnis auf die minimale Federkraft.The rotary damper (71) has a constant torque, for example. In the exemplary embodiment, this moment is 0.010 Newtons times meters. However, it is also conceivable to use a rotary damper (71) with a higher or lower torque. For example, the torque is between 0.005 and 0.015 Newtons times meters. At the fixation of the spiral spring (51), the circumferential force of the rotary damper (71) is thus 85% of the force of the spiral spring (51). The circumferential force of the rotary damper (71) at this point can be between 70% and 98% of the spring force. In the case of a spiral spring (51) with a spring force that can be varied over its length, the ratio mentioned relates to the minimum spring force.

Im Warenschieber (30) ist in dem in der Förderrichtung (11) hinten liegenden Abschnitt das Leitelement (60) angeordnet. Dieses Leitelement (60) ist parallel zur Rotationsachse des rotierbaren Teils (104) angeordnet. Es übergreift den Rotationsdämpfer (71) und die Spiralfeder (51). Im Ausführungsbeispiel ist das Leitelement (60) ein schalenförmiges Bauteil, das den rotierbaren Teil (104) des Rotationsdämpfers (71) und die Spiralfeder (51) in Umfangsrichtung bereichsweise umgibt. Beispielsweise umgreift es den Rotationsdämpfer (71) und die Spiralfeder (51) in einem Sektor von 200 Grad. Es hat eine Einführkante (61), an der in der Darstellung der Figur 9 die Spiralfeder (51) beim Aufwickeln in der Aufwickelrichtung (56) unter das Leitelement (60) geführt wird. Die Einführkante (61) des Leitelements (60) schließt mit einer Normalenebene zur Förderrichtung (11) in der Darstellung der Figur 9 einen Winkel von 38 Grad ein. Das im Ausführungsbeispiel als separates Bauteil ausgeführte Leitelement (60) kann auch im Gehäuse (34) des Warenschiebers (30) integriert sein. Gegebenenfalls ist dann das Leitelement (60) in das Gehäuse (34) eingeformt oder an dieses angeformt. Das Leitelement (60) kann auch am feststehenden Teil (103) des Rotationsdämpfers (71) angeordnet sein oder in dieses integriert sein.In the goods pusher (30), the guide element (60) is arranged in the section lying at the rear in the conveying direction (11). This guide element (60) is arranged parallel to the axis of rotation of the rotatable part (104). It engages over the rotary damper (71) and the spiral spring (51). In the exemplary embodiment, the guide element (60) is a shell-shaped component which partially surrounds the rotatable part (104) of the rotary damper (71) and the spiral spring (51) in the circumferential direction. For example, it encompasses the rotary damper (71) and the spiral spring (51) in a sector of 200 degrees. It has a lead-in edge (61) on which, in the illustration, the Figure 9 the spiral spring (51) is guided under the guide element (60) during winding in the winding direction (56). The lead-in edge (61) of the guide element (60) closes with a plane normal to the conveying direction (11) in the illustration of FIG Figure 9 an angle of 38 degrees. The guide element (60), which is designed as a separate component in the exemplary embodiment, can also be integrated in the housing (34) of the goods pusher (30). If necessary, the guide element (60) is then molded into the housing (34) or molded onto it. The guide element (60) can also be arranged on the stationary part (103) of the rotary damper (71) or integrated into it.

Das Leitelement (60) kann auch stiftartig oder mit drehbaren Rollen ausgeführt sein, wobei jeweils der Stift bzw. die Rotationsachse der Rolle parallel zur Rotationsachse des rotierbaren Teils (104) orientiert ist. Bei einer Ausführung mit Rollen können deren Lagerzapfen z.B. in das Gehäuse (34) eingeclipst sein. Beispielsweise bei einem zylindrischen Stift ist die Einführkante (61) die Berührlinie derjenigen Tangentialebene an das Leitelement (60), die die Rotationsachse durchdringt. Es ist auch denkbar, dass mehrere z.B. drei Stifte das Leitelement (60) bilden. Die Stifte sind dann beispielsweise entlang einer koaxial zur Rotationsachse liegenden gedachten Hüllfläche angeordnet.The guide element (60) can also be designed like a pin or with rotatable rollers, the pin or the axis of rotation of the roller in each case being oriented parallel to the axis of rotation of the rotatable part (104). In an embodiment with rollers, their bearing journals can be clipped into the housing (34), for example. In the case of a cylindrical pin, for example, the lead-in edge (61) is the line of contact of that tangential plane on the guide element (60) which penetrates the axis of rotation. It is also conceivable that several, for example three, pins form the guide element (60). The pins are then arranged, for example, along an imaginary envelope surface lying coaxially to the axis of rotation.

Der Winkel, den eine Radiale durch die Einführkante (61) und die Rotationsachse in einer gemeinsamen Ebene mit einer Radialen durch die Abhebelinie (55) und die Rotationsachse des rotierbaren Teils (104) einschließt, beträgt maximal 30 Grad.The angle enclosed by a radial through the lead-in edge (61) and the axis of rotation in a common plane with a radial through the lever line (55) and the axis of rotation of the rotatable part (104) is a maximum of 30 degrees.

Bei einem schalenförmigen Leitelement (60) liegt der vom Leitelement (60) umgriffene Sektor des rotierbaren Teils (104) zumindest in einem Winkel zwischen 40 Grad und 90 Grad in Bezug auf die genannte Normalenebene zur Förderrichtung (11). Hierbei liegt die Einführkante (61) auf einer Radialen, die den erstgenannten Winkel mit der Normalenebene einschließt.In the case of a bowl-shaped guide element (60), the sector of the rotatable part (104) encompassed by the guide element (60) lies at least at an angle between 40 degrees and 90 degrees with respect to the aforementioned normal plane to the conveying direction (11). Here, the lead-in edge (61) lies on a radial line that encloses the first-mentioned angle with the normal plane.

Das im Ausführungsbeispiel dargestellte Leitelement (60), vgl. die Figuren 9 und 12, hat an seiner Außenseite (63) Verstärkungsrippen (64) und einen Anlageflansch (65). Mit dem Anlageflansch (65) liegt das Leitelement (60) im Gehäuse (34) des Warenschiebers (30) an. Gegebenenfalls ist es dort fixiert oder befestigt, z.B. verklebt.The guide element (60) shown in the exemplary embodiment, see Figures 9 and 12th , has reinforcing ribs (64) and a contact flange (65) on its outside (63). The guide element (60) rests with the contact flange (65) in the housing (34) of the goods pusher (30). If necessary, it is fixed or fastened there, for example glued.

Die Schale (62) hat eine weitgehend konstante Dicke. Diese beträgt beispielsweise das Fünffache der Dicke der Spiralfeder (51). Die Schale (62) hat eine glatte Innenwandung (66), die einen niedrigen Reibungskoeffizienten gegen Federstahl aufweist. Sie ist z.B. koaxial zur Achse des rotierbaren Teils (104) angeordnet. Die Schale (62) hat damit einen konstanten Abstand zum rotierbaren Teil (104). Ihr radialer Abstand zum rotierbaren Teil (104) ist kleiner oder gleich dem Siebenfachen der Dicke der Spiralfeder (51). Die Einführkante (61) ist abgerundet ausgebildet.The shell (62) has a largely constant thickness. This is, for example, five times the thickness of the spiral spring (51). The shell (62) has a smooth inner wall (66) which has a low coefficient of friction against spring steel. For example, it is arranged coaxially with the axis of the rotatable part (104). The shell (62) is thus at a constant distance from the rotatable part (104). Their radial distance from the rotatable part (104) is less than or equal to seven times the thickness of the spiral spring (51). The lead-in edge (61) is rounded.

Die Trag- und Führungsschiene (20) ist beispielsweise so aufgebaut, wie im Zusammenhang mit dem ersten Ausführungsbeispiel beschrieben. Die Führungslänge des Warenschiebers (30) in der Trag- und Führungsschiene ist z.B. größer oder gleich der doppelten Breite der durch die Führungsleisten (31) bestimmten Führungsbreite. Beispielsweise beim Einsatz einer symmetrisch zur Mittenlängsebene des Führungssystems (10) angeordneten Spiralfeder (51) kann die Führungslänge kürzer ausgebildet sein. Beispielsweise beträgt sie dann das 1,5-fache der Führungsbreite.The support and guide rail (20) is constructed, for example, as described in connection with the first exemplary embodiment. The guide length of the goods pusher (30) in the The carrier and guide rail is, for example, greater than or equal to twice the width of the guide width determined by the guide strips (31). For example, when using a spiral spring (51) arranged symmetrically to the central longitudinal plane of the guide system (10), the guide length can be made shorter. For example, it is then 1.5 times the guide width.

Der Frontanker (80) ist beispielsweise in dem in der Förderrichtung (11) vorne liegenden Ende der Trag- und Führungsschiene (20) verrastet oder geklemmt. Er kann außerdem einen vorderen Anschlag für die Waren bilden oder aufweisen und den Hub des Warenschiebers (30) begrenzen.The front anchor (80) is latched or clamped, for example, in the end of the support and guide rail (20) which is at the front in the conveying direction (11). It can also form or have a front stop for the goods and limit the stroke of the goods pusher (30).

Bei der Montage des Fördersystems (10) wird beispielsweise zunächst die Spiralfeder (51) am rotierbaren Teil (104) des Rotationsdämpfers (71) fixiert. Zusammen mit dem aufgesetzten Leitelement (60) wird diese Einheit in das Gehäuse (34) eingesetzt und dort gegebenenfalls fixiert.When assembling the conveyor system (10), for example, the spiral spring (51) is first fixed on the rotatable part (104) of the rotary damper (71). Together with the attached guide element (60), this unit is inserted into the housing (34) and optionally fixed there.

Das freie Ende der Spiralfeder (51) wird durch den Durchführschlitz (44) hindurchgeführt. Nach dem Einsetzen des Warenschiebers (30) in die Trag- und Führungsschiene (20) wird das freie Ende der Spiralfeder (51) z.B. am Frontanker (80) befestigt. Nach der Montage steht der Warenschieber (30) am vorderen Ende der Trag- und Führungsschiene (20). Die Spiralfeder (51) ist auf dem rotierbaren Teil (104) des Rotationsdämpfers (71) aufgerollt.The free end of the spiral spring (51) is passed through the feed-through slot (44). After inserting the pusher (30) into the support and guide rail (20), the free end of the spiral spring (51) is attached to the front anchor (80), for example. After assembly, the goods pusher (30) is at the front end of the support and guide rail (20). The spiral spring (51) is rolled up on the rotatable part (104) of the rotary damper (71).

Zum Einsetzen der Waren wird der Warenschieber (30) entgegen der Förderrichtung (11) entlang der Trag- und Führungsschiene (20) nach hinten verschoben. Die Spiralfeder (51) wird abgewickelt. Beispielsweise liegt die abgewickelte Spiralfeder (51) zwischen dem Warenschieber (30) und dem Frontanker (80) unterhalb der Waren. Nach dem Laden der Waren steht der Warenschieber (30) z.B. in der hinteren Position. Die Antriebsvorrichtung (50) drückt den Warenschieber (30) mit dem Schubschild (32) gegen die Reihe der in das Fördersystem (10) eingesetzten Waren. Auch dieses Fördersystem (10) kann beispielsweise bis auf die erste Ware abgedeckt sein. Damit kann vom Kunden nur die jeweils erste Ware entnommen werden.To insert the goods, the goods pusher (30) is moved backwards against the conveying direction (11) along the support and guide rail (20). The spiral spring (51) is unwound. For example, the unwound spiral spring (51) lies between the goods pusher (30) and the front anchor (80) below the goods. After the goods have been loaded, the goods pusher (30) is in the rear position, for example. The drive device (50) presses the goods pusher (30) with the pusher plate (32) against the row of goods inserted into the conveyor system (10). This conveyor system (10) can also be covered, for example, except for the first item. This means that the customer can only remove the first item in each case.

Sobald eine Ware entnommen ist, entsteht ein Freiraum in der Reihe der Waren. Die sich aufrollende Spiralfeder (51) dreht den rotierbaren Teil (104) des Rotationsdämpfers (71). Hierbei kann der Rotationsdämpfer (71) die Aufrollbewegung der Spiralfeder (51) verzögern. Gleichzeitig wirkt die sich aufrollende Spiralfeder (51) in der Förderrichtung (11) auf den Rotationsdämpfer (71). Der feststehende Teil (103) des Rotationsdämpfers (71) verschiebt den Warenschieber (30) in der Förderrichtung (11). Die im Fördersystem (10) verbliebenen Waren werden mittels des Schubschilds (32) so weit in der Förderrichtung (11) verschoben, bis z.B. ein Anschlag das weitere Fördern der Waren blockiert. Jetzt liegt die nächste Ware in der Entnahmeposition.As soon as a product is removed, there is a free space in the row of products. The coiled coil spring (51) rotates the rotatable part (104) of the rotary damper (71). Here, the rotary damper (71) can delay the rolling-up movement of the spiral spring (51). At the same time, the spiral spring (51) that rolls up acts on the rotary damper (71) in the conveying direction (11). The fixed part (103) of the rotary damper (71) moves the goods pusher (30) in the conveying direction (11). The goods remaining in the conveyor system (10) are pushed by means of the pusher plate (32) in the conveying direction (11) until, for example, a stop blocks the further conveyance of the goods. The next product is now in the removal position.

Beim Fördern wirken die Massenträgheit und die Reibung des Warenschiebers (30) und der Waren sowie das Drehmoment des Rotationsdämpfers (71) der Beschleunigung durch die Spiralfeder (51) entgegen. Schwankungen dieser Kräfte, die z.B. durch eine Änderung der Anzahl der Waren im Fördersystem (10) verursacht sein können, können die Gleichförmigkeit der Vorschubbewegung des Warenschiebers (30) beeinträchtigen.During conveying, the inertia and the friction of the goods pusher (30) and the goods as well as the torque of the rotary damper (71) counteract the acceleration by the spiral spring (51). Fluctuations in these forces, which can be caused, for example, by a change in the number of goods in the conveyor system (10), can impair the uniformity of the feed movement of the goods pusher (30).

Beispielsweise bei derartigen Schwankungen kann die Spiralfeder (51) beim Aufwickeln vom rotierbaren Teil (104) des Rotationsdämpfers (71) abheben. Sie stößt dann gegen die Schale (62) des Leitelements (60) und wird in die Aufwickelrichtung (56) geleitet. Beispielsweise verzögert ein Anlegen der Spiralfeder (51) am Leitelement (60) den Warenschieber (30), sodass die sich weiter aufwickelnde Spiralfeder (51) sich wieder straffen kann. Hierdurch wird beispielsweise die Schwankungsbreite der Geschwindigkeit des Warenschiebers (30) vermindert. Das Fördersystem erreicht damit eine weitgehend gleichförmige Förderbewegung.With such fluctuations, for example, the spiral spring (51) can lift off the rotatable part (104) of the rotary damper (71) when it is being wound up. It then abuts against the shell (62) of the guide element (60) and is in the winding direction (56) headed. For example, applying the spiral spring (51) to the guide element (60) delays the goods pusher (30) so that the spiral spring (51), which continues to wind up, can tighten again. In this way, for example, the range of fluctuation in the speed of the goods pusher (30) is reduced. The conveyor system thus achieves a largely uniform conveying movement.

Aufgrund des großen Durchmessers des rotierbaren Teils (104) des Rotationsdämpfers (71) hat dieser einen großen Umfang. Entlang des Hubs des Warenschiebers (30) entstehen nur wenige Wickellagen der Spiralfeder (51). Der Rotationsdämpfer (71) mit der teilaufgewickelten Spiralfeder (51) hat damit entlang des Hubes des Warenschiebers (30) ein weitgehend gleichbleibendes Dämpfungsverhalten. Das Verhältnis zwischen der Zugkraft der Spiralfeder (51) und der ihr entgegenwirkenden Umfangskraft des Rotationsdämpfers (71) ist damit über den Hub des Warenschiebers (30) zumindest annähernd konstant.Due to the large diameter of the rotatable part (104) of the rotary damper (71), it has a large circumference. There are only a few winding layers of the spiral spring (51) along the stroke of the goods pusher (30). The rotary damper (71) with the partially wound spiral spring (51) thus has a largely constant damping behavior along the stroke of the goods pusher (30). The ratio between the tensile force of the spiral spring (51) and the counteracting circumferential force of the rotary damper (71) is thus at least approximately constant over the stroke of the goods pusher (30).

Bei der genannten Auslegung des Rotationsdämpfers (71) und der Spiralfeder (51) erfahren die Waren beim Fördern nur eine geringe Beschleunigung. Die Waren haben somit eine geringe Massenträgheit, sodass die Gegenkraft gegen die resultierende Vorschubkraft im Wesentlichen durch die Überwindung der Haftreibung verursacht wird.With the stated design of the rotary damper (71) and the spiral spring (51), the goods experience only a slight acceleration during conveyance. The goods therefore have a low mass inertia, so that the counterforce against the resulting feed force is essentially caused by overcoming the static friction.

Die Waren werden auch in diesem Ausführungsbeispiel nach der Entnahme einer Ware langsam und schlagfrei in der Förderrichtung (11) verschoben.In this exemplary embodiment, too, the goods are shifted slowly and without impact in the conveying direction (11) after a goods have been removed.

Auch Kombinationen der verschiedenen Ausführungsbeispiele sind denkbar.Combinations of the various exemplary embodiments are also conceivable.
