Abstract

The invention relates to a stacking device for flat postal items standing on edge. Said stacking device comprises guide means for guiding the postal items (11, 12) supplied to it to a stacking position on a stacking base (1) against a support wall (2) on which the postal items (11, 12) are slowed down. The stacking device is further provided with a stacker plate (5) that can be displaced in the direction of stacking along a linear guide (3, 4). Said stacker plate cooperates with a spring element to produce a pressure force that is approximately constant across the zone of displacement and that is directed against the forming stack. The movable part of a damper element is fastened on the movable part of the spring element, said damper element being only active when a displacement directed away from the stacking position is exerted. If the spring element is configured as a constant-force spring (9) wound up on a coil (8), a rotation damper (6) is fastened on the coil (8) that is effective only in the case of an unwinding movement in such a manner that the rotating parts and the stationary parts are interlinked.

Description

Die Erfindung betrifft eine Stapelvorrichtung für flache, auf ihren Schmalseiten stehende Sendungen. Sie enthält Führungsmittel zum leiten der zugeführten Sendungen auf eine Stapelunterlage gegen eine Stützwand, an der die Sendungen abgebremst werden. Sie enthält weiterhin eine in Stapelrichtung an einer Linearführung verschiebbare Stapelplatte, an die eine auf einer Spule aufgewickelte Rollfeder zur Erzeugung einer über den Verschiebebereich annähernd gleichen, zum sich aufbauenden Stapel gerichteten Andruckkraft angreift.The invention relates to a stacking device for flat, on programs standing on their narrow sides. It contains management tools for routing the consignments to a stacking pad against a supporting wall on which the shipments slowed down become. It also contains one in the stacking direction on a linear guide slidable stacking plate to which one Roll spring wound on a spool to produce a approximately the same over the range of displacement to themselves building stack attacks directed pressure force.

Die Rollfeder ist so ausgelegt, dass bei Sendungen mit geringer kinetischer Energie aufgrund des durch die jeweilige einlaufende Sendung auf die Stapelplatte ausgeübte Kraft die Stapelplatte von der Einstapelstelle weg verschoben wird.The roller spring is designed so that for shipments with less kinetic energy due to the incoming through the Consignment exerted force on the stacking plate Stacking plate is moved away from the stacking point.

Werden Sendungen mit einer relativ hohen kinetischen Energie (v=4m/s, m>30g) eingestapelt, wird durch den Impuls, der durch das Auftreffen der Sendungen auf die Stapelplatte bzw. den sich aufbauenden Stapel entsteht, die Stapelplatte entgegen der Kraft der Rollfeder von der Sendung bzw. vom Stapel impulsartig wegbewegt. Dadurch verliert die Stapelplatte kurzzeitig den Kontakt zu den Sendungen und die einzustapelnde Sendung prallt von der Stützwand ab.Are shipments with a relatively high kinetic energy (v = 4m / s, m> 30g) is stacked by the momentum by the impact of the mail items on the stacking plate or the stack that builds up, counter the stacking plate the force of the roller spring from the shipment or from the stack moved away impulsively. As a result, the stacking plate loses short-term contact with the shipments and the items to be stacked Consignment bounces off the retaining wall.

Um diesen Effekt zu verhindern, wurde eine Lösung bekannt (EP 0 626 927 B1) die dem Oberbegriff des Anspruchs 1 entspricht und bei der an der Stapelplatte zusätzlich zur von der Rollfeder erzeugten Kraft im Anfangsbereich des Bewegungsbereiches der Stapelplatte nahe der Einstapelstelle eine weitere Kraft durch eine mit der Stapelplatte zusammenwirkende Keilprofilplatte erzeugt wird. Wird eine relativ schwere Sendung eingestapelt, so wird die zum sicheren Halten benötigte, über der Federkraft liegende Kraft an der Stapelplatte durch Kontakt mit den Rampenflächen der Keilprofilplatte erzeugt. Diese Kraft kann sich nur diskontinuierlich verändern und kann nur im ersten Teil des Sendungsstapels erzeugt werden. Obwohl der Stapel mit zunehmender Dicke elastischer wird, und damit ein Wegspringen vom Stapel häufig verhindert wird, kann es vorkommen, dass auch bei einem schon eingestapelten Stapel (z.B. bei mehreren eingestapelten, dicken und harten Sendungen) mit größerer Stapeldicke ein impulsartiges Wegbewegen der Stapelplatte von der Sendung auftritt.A solution has been found to prevent this effect (EP 0 626 927 B1) which corresponds to the preamble of claim 1 and in which in addition to the stacking plate force generated by the roller spring in the initial area of the range of motion the stacking plate near the stacking point further force by interacting with the stacking plate Wedge profile plate is generated. Will be a relatively heavy one Consignment stacked, so that is needed for safe holding Force above the spring force on the stacking plate generated by contact with the ramp surfaces of the spline plate. This force can only change discontinuously and can only be created in the first part of the batch. Although the stack becomes more elastic with increasing thickness is often prevented from jumping off the stack , it can happen that even with a stacked Stack (e.g. with several stacked, thick and hard shipments) with a larger stack thickness an impulse-like Moving the stacking plate away from the shipment occurs.

Der im Anspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Stapelvorrichtung mit einer Stapelplatte, die durch ein Federelement gegen den Stapel gedrückt wird, zu schaffen, mit der über den gesamten Stapelbereich unabhängig von der Höhe der kinetischen Energie von in die Einstapelstelle einlaufende Sendungen ein impulsartiges Entfernen der Stapelplatte vom Stapel verhindert wird, wobei die erhöhte Gegenkraft stets proportional zur kinetischen Energie erzeugt wird.The invention specified in claim 1 is the object based on a generic stacking device with a Stacking plate pressed against the stack by a spring element is going to create, with over the entire stacking area regardless of the level of kinetic energy of in the incoming batches a pulse-like Removing the stacking plate from the stack is prevented, whereby the increased counterforce is always proportional to the kinetic Energy is generated.

Die Dämpfung der Bewegung der Stapelplatte über dem gesamten Bewegungsbereich durch den kurzzeitigen Abbau der zu hohen Energie bei schweren Sendungen wirkt umso mehr, je höher die kinetische Energie der einzustapelnden Sendung ist. Je höher die kinetische Energie der einlaufenden Sendung ist, desto höher ist das Bremsmoment des Dämpfungselementes, hervorgerufen durch die höhere Geschwindigkeit, mit der sich die Stapelplatte vom Sendungsstapel entfernen will.Damping the movement of the stacking plate over the whole Movement area due to the short-term reduction of the too high The higher the energy, the greater the impact on heavy shipments is kinetic energy of the shipment to be stacked. The higher the kinetic energy of the incoming shipment is the more the braking torque of the damping element is higher by the higher speed at which the stacking plate wants to remove from the shipment stack.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen dargestellt.Advantageous embodiments of the invention are in the subclaims shown.

Vorteilhaft ist es, bei einer Ausbildung des Federelementes als Rollfeder an die Spule der Rollfeder einen nur bei der Abwickelbewegung wirkenden Rotationsdämpfer so zu befestigen, dass die sich drehenden Teile und die feststehenden Teile miteinander verbunden sind. Dabei ist es vorteilhaft, den Rotationsdämpfer mit einem Freilauf auszustatten.It is advantageous if the spring element is designed as a scroll spring to the coil of the scroll spring only at the To fix the unwinding rotary damper in such a way that the rotating parts and the fixed parts are interconnected. It is advantageous to use the rotary damper to be equipped with a freewheel.

Zum Ausgleich von Toleranzen ist es vorteilhaft, den Rotationsdämpfer über eine Lageabweichungen ausgleichende Kupplung mit der Spule zu verbinden.To compensate for tolerances, it is advantageous to use the rotary damper via a coupling compensating for deviations to connect with the coil.

Anschließend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnung näher erläutert.

Wie in FIG 1 zu erkennen, besitzt die Unterlage 1 zwei Gleitschienen, auf denen die Sendungen bei wachsendem Stapel mit möglichst geringem Reibungswiderstand rutschen. Annähernd senkrecht dazu befindet sich eine Stützwand 2, an der eine runde Führungsschiene 3 einer Linearführung befestigt ist. Auf der Führungsschiene 3 läuft eine Kugelbuchse 4, an der eine schwenkbare Stapelplatte 5 angebracht ist. Die Sendungen gelangen vom Betrachter rechts über den rechten Gang einer Stapelspindel 7 schräg auf die Stapelplatte 5 bzw. später auf die vorderste Sendung des Stapels und üben auf die Stapelplatte 5 einen Impuls aus, so dass sie von der Einstapelstelle weg verschoben wird. Die sich drehende Stapelspindel 5 sorgt dafür, dass der hintere Teil der Sendungen schnell nach links bewegt wird. Damit wird sichergestellt, dass die im kurzen Abstand folgende nächste Sendung nicht auf die Hinterkante der vorangehenden Sendung stößt. Zu sehen ist auch noch der Rotationsdämpfer 6, dessen Funktion im folgenden anhand der FIG 2 näher erläutert wird.As can be seen in FIG. 1, the base 1 has two slide rails, on which the shipments with a growing stack slip as little friction resistance as possible. Nearly perpendicular to it is a support wall 2 on which one round guide rail 3 is attached to a linear guide. On the guide rail 3, a ball bushing 4 runs on the a pivotable stacking plate 5 is attached. The broadcasts get from the viewer to the right via the right aisle Stacking spindle 7 at an angle on the stacking plate 5 or later the foremost shipment of the stack and practice on the stacking plate 5 an impulse so that it is from the stacking point is moved away. The rotating stacking spindle 5 ensures that the rear part of the shipments quickly after is moved to the left. This ensures that the im short distance following next shipment not on the rear edge of the previous broadcast. You can still see it the rotary damper 6, the function of which is described below 2 is explained in more detail.

An der verschiebbaren Kugelbuchse 4 ist ein Ende einer bandförmigen Rollfeder 9 befestigt, die auf einer drehbar gelagerten Spule 8 aufgewickelt ist. Das andere Ende der Rollfeder 9 kann mit der Spule 8 verbunden werden oder wird nur durch die Reibung auf der Spule 8 gehalten. Durch die Rollfeder 9 wird infolge ihrer flachen Federkennlinie über den gesamten Verschiebebereich die Stapelplatte 5 mit annähernd konstanter Kraft gegen den sich aufbauenden Sendungsstapel gedrückt. Die Spule 8 ist über eine Kupplung 10, die für Ausgleich von Verschiebungen und Ungenauigkeiten sorgt mit einem nur in einer Drehrichtung wirkenden Rotationsdämpfer 6 verbunden, wobei die beweglichen Teile miteinander und die unbeweglichen Teile miteinander verbunden sind. Der Rotationsdämpfer 6 besitzt einen Freilauf und wirkt nur beim Abwickeln der Rollfeder 9, so dass das Aufwickeln der Rollfeder 9 dämpfungsfrei und somit schnell erfolgt. Bei Einstapeln von Sendungen 11,12 mit einer Masse > ca. 30g und einer Einstapelgeschwindigkeit von ca. 4m/s wird die kinetische Energie über den Rotationsdämpfer 6 abgebaut, indem die Stapelplatte 5 versucht, sich impulsartig mit einer Geschwindigkeit, die durch das Aufprallen der Sendung 11,12 gegen die Stützwand 2 und die Stapelplatte 5 oder den Sendungsstapel hervorgerufen wird, entlang der Linearführung zu bewegen. Da die Energie durch den Rotationsdämpfer 6 kurzzeitig abgebaut wird, verliert die Stapelplatte 5 nie den Kontakt zum Briefstapel. Sendungen 11,12 mit einer Masse < ca. 30g haben bei der Einstapelgeschwindigkeit von 4m/s nur eine geringe kinetische Energie, so dass die Stapelplatte 5 nicht versucht, den Briefstapel entgegen der Federkraft impulsartig zu verlassen. At the sliding ball bushing 4 is one end of a band-shaped Scroll spring 9 attached to a rotatably mounted Coil 8 is wound. The other end of the roller spring 9 can be connected to the coil 8 or will only held by the friction on the coil 8. By the roller spring 9 is due to its flat spring characteristic over the entire Sliding area of the stacking plate 5 with approximately constant force against the stack of mail building up pressed. The coil 8 is via a clutch 10, which is used for compensation of shifts and inaccuracies ensures with one only connected in one direction of rotation damper 6, the moving parts together and the immovable Parts are interconnected. The rotation damper 6 has a freewheel and only works when unwinding the roller spring 9, so that the winding of the roller spring 9 is damping-free and thus takes place quickly. When items are stacked 11.12 with a mass> approx. 30g and a stacking speed The kinetic energy is about 4m / s dismantled the rotary damper 6 by the stacking plate 5 tries to get impulsive at a speed that by the impact of the consignment 11, 12 against the supporting wall 2 and the stacking plate 5 or the stack of mail items will move along the linear guide. Because the energy is briefly degraded by the rotary damper 6, loses the stacking plate 5 never makes contact with the stack of letters. Consignments 11, 12 with a mass <approx. 30 g have the stacking speed of 4m / s only a low kinetic Energy so that the stacking plate 5 does not attempt the Leaving stack of letters against the spring force in an impulsive manner.

In den FIG 3 und 4 ist die Stapelvorrichtung mit sich aufbauenden Sendungsstapel, beginnend mit der ersten Sendung 11 und mit der zweiten Sendung 12 dargestellt.3 and 4, the stacking device is built up Mail batch, starting with the first mail 11 and shown with the second shipment 12.
