Definitions

  • the invention relates to a sorting conveyor with a number of transport trolleys which have laterally tiltable storage trays for piece goods to be sorted.
  • Such a sorting conveyor is known from German patent DE 40 42 708 C2.
  • a sorting conveyor is described therein, which has a circumferential row of support units for laterally tiltable storage trays, which are moved past a storage station along a conveyor chassis and are loaded there with piece goods to be sorted.
  • the carrying units loaded with piece goods are then moved past a row of unloading or receiving stations in which the storage trays can be selectively tilted by means of actuating arms arranged on both sides in order to unload the piece goods to be sorted.
  • the carrying units are designed as transport carriages or units which have guide parts which engage in the conveying chassis at a greater distance from one another.
  • the transport carriages are provided with elongated drive parts which extend in the direction of advance of the carrying units and are designed to interact with linear motors which are fixed in fixed positions along the conveyor chassis.
  • the problem with the above-mentioned tilting conveyor is fundamentally the fact that the piece goods parts to be tipped can have very different sliding properties due to their external properties, which in particular with comparatively heavy and not particularly slip-resistant piece goods parts in a considerable mechanical stress on the guide link or even moving back Tray can lead to its basic position. In such a case, the result is a new one
  • the invention is therefore based on the object of specifying a sorting conveyor which can be equipped in a particularly needs-based manner and also carries out the sorting of comparatively heavy and not particularly slippery piece goods parts safely and reliably.
  • a sorting conveyor of the type mentioned at the outset in that a) the transport carriages have a support unit for the storage trays which can be pivoted about a tilting axis; b) a lever arm that can be steered into a backdrop and engages on the support unit is provided; c) the transport carriages comprise a base module receiving the carrying unit; and d) the base module has guide means for the tilting movement of the supporting unit and a lifting movement of the lever arm which triggers the tilting movement.
  • the tilting device engages directly on the carrying unit, so that different storage trays can be used and the storage trays can be exchanged easily. Furthermore, the pressure of the part of the piece of goods acting according to gravity will be absorbed particularly well in the transport carriage, because the lever arm is guided in the base module provided with the guides and is also held therein.
  • a particularly simple construction of the transport trolleys is achieved with the creation of the basic module. For example, a two-part basic module is conceivable, which consists of two halves that are mirror-inverted to each other, which have guideways in the form of cavities designed as guide means, and thus also restrict the mobility of the carrying unit and the lever arms in each case in a two-dimensional plane. Different tilt angles can easily can be achieved by choosing an appropriate basic module.
  • lever arm can be guided in a two-dimensionally extending backdrop, because the lever arm only has to perform a linear movement essentially vertically upwards or downwards and tilted in the base module for this purpose is.
  • lever arm acts on the support unit on a sliding fit without bearing, as a result of which an additional bearing and its assembly are not required.
  • a low overall depth of the sorting conveyor is achieved if the storage trays can be tilted on both sides and two mutually independently movable lever arms are provided which engage on the support unit on a sliding fit. In this way, only one of the two lever arms is used for tilting moved up or down, the support unit gliding past the other non-activated lever arm.
  • This embodiment variant has a particularly favorable effect when the lever arm is actively pushing upward, because the other lever arm is not correspondingly pressed downward and therefore there is no space requirement for this lever arm, which is otherwise always passively moved in the prior art.
  • a particular advantage of this construction is that a maximum tilt angle of the support unit can be predetermined by an appropriate design of the guide means. In this way, different tilt angles can be implemented in a simple manner by means of correspondingly different base modules, as a result of which the lever arms and the support unit as such can remain unchanged.
  • lever arm has projecting cup-shaped cams and is guided by means of these cams in a substantially vertical guideway, the base and end positions being realized by a receptacle branching off the side of the guideway is.
  • a feature which increases the operational safety immensely provides, in an embodiment of the invention, that a lever arm tilting the support unit pivots the support unit at the start of the unlocking movement in such a way that an unlocking movement of the other lever arm is blocked.
  • Another particularly reliable system is achieved if an addition to the above-mentioned feature is provided in such a way that the lever arms can be controlled into the link by means of a control element which can be guided in the control position, the control elements - viewed in the conveying direction - being arranged slightly offset from one another.
  • a faulty control attempt both control elements in the control position only destroys the following control element in the conveying direction. Damage to the trolley and / or to the scenery can be avoided in this way.
  • This means that the entire sorting conveyor can continue to be operated except for a destination that can then no longer be operated or can only be operated on one side, thereby contributing to a high availability of the sorting conveyor.
  • An alternative to the above-described embodiment provides for a two-part construction of the lever arm with an enveloping body and a deflecting lever, the enveloping body engaging on the sliding unit on a sliding fit and essentially being movable only in the stroke direction, and the deflecting lever being arranged essentially parallel in the enveloping body and is connected in an articulated manner to the enveloping body with its upper end facing the carrying unit and can be driven into the scenery with its opposite lower end. In this way, only a one-dimensional movement of the lever arm is ensured in the base module.
  • a particularly preferred embodiment of the tilting mechanism then consists in that a tilting and locking movement of the storage tray is achieved in that the lower end of the deflection lever for releasing the locked basic position within the dimensions of the enveloping body in a first pivoting direction, i.e. oriented in a direction substantially perpendicular to the stroke direction, is pivotable, is movable in the stroke direction to achieve the tilting movement and is pivotable for locking the tilted end position in a second pivoting direction, which is oriented antiparallel to the first pivoting direction.
  • the above-mentioned construction enables a construction that is very simple to implement Way also the realization of very different tilt angles with locking of the tilted position when the base module and the deflection lever have mutually corresponding cams and receptacles for the cams, the cams and the receptacles being arranged one behind the other in the stroke direction.
  • a stop for limiting the tilting movement can be provided for the enveloping body and / or the carrying unit.
  • the stop can be designed to be adjustable in height.

  • the support unit 4, 4 ' is held pivotably about an axis 8 running parallel to the conveying direction and is shown in the figure in the position tilted to the right.
  • the support unit 4 with cam-shaped pins 10, 10 ' is only guided with the deflection in an arcuate guideway 12 which is formed in a base module 14.
  • the base module 14 thus also serves to carry the carrying unit 4 and provides a connection to drive elements of the sorting conveyor, not shown here, e.g. Linear motors, and the neighboring transport car.
  • lever arms 16, 16 ' are also guided in the base module 14, in the present exemplary embodiment the lever arm 16' on the left-hand side causing the storage tray 6 to tilt by a stroke movement 18.
  • the lever arm arranged on the other side here the Lever arm 6 'to control a link 28, 28' which, in the present exemplary embodiment, specifies a curve which is only two-dimensionally curved in space and which the lever arm 16 'has to follow.
  • the lever arms 16, 16 ' have a friction-mounted cam follower roller 30, 30' which is driven into the link 28, 28 'by means of a control element (not shown here).
  • the locking consists in that the roller-supported pin 26 ′ is mounted in the park position in a first bulge 32, which is located on the side of the guide track 22 and is part of the guide track 22, and is pivoted in a first pivoting direction 36 by means of a deflection roller 34.
  • the deflection roller 34 would also be dispensable because the function of the deflection roller 34 can also be achieved directly by an attack on the cam follower roller if the control element is designed accordingly.
  • the first pivot direction 36 is oriented essentially perpendicular to the stroke movement 18. The first pivoting movement takes place about the axis of the pin 24 '.
  • the lifting movement 18 then follows with the tilting of the support unit 4 'and the storage tray 6'.
  • the tilting movement shown is in this status.
  • To lock the tilted position there is finally a movement in a second pivoting direction 38 antiparallel to the first pivoting direction 36.
  • the roller-supported pin 26 'then rests in a second bulge 40 laterally at the end of the vertically ascending section of the guideway 22 and can no longer directly down or be pressed at the top. This ensures that the storage tray 6 'remains permanently in the tilted position until the transport carriage 2 passes a reset link, not shown here, and a reverse movement of the lever arm 16' is achieved.
