Definitions
- the invention relates to a device for stacking flat mail items according to the preamble of patent claim 1.
- Asynchronous systems or parts are coupled by the storage devices used for this purpose.
- One storage technique for shipments is to stack the shipments.
- a stacking device usually consists of a stationary separating mechanism and a stacking mechanism that can be moved in the stacking direction, between which the stack of mail items is located. The bottom of the stack of items forms a stacking surface.
- Two endless belts, which rotate on rollers, form a transport route which conveys the individually arriving mail items to the end of the stack. Between the stacking mechanism and the entry point of the mail items, the two belts form a straight section of the transport path on which the belts are free, i.e. not run by rollers, run.
- this section of the transport path depends on the respective position of the stacking mechanism during the stacking process. As the stack of items grows, this section becomes shorter. It reaches its maximum length if there is no batch of mail items and the stacking mechanism is located directly on the separating mechanism.
- the storage capacity that can be achieved with this structure is indeed higher than that which can be achieved with a shed storage with comparable technical effort, in which the mail items are clamped between belts in a scaly manner.
- Problems arise with the device of the type described above when the straight section of the transport route reaches its maximum length. In this case, several shipments can be on the section at the same time.
- a thin consignment that is between two thick consignments is not securely gripped by the straps. If there are several thin consignments between two thick consignments, the thin consignments can slide on one another, with the result of a traffic jam in the transport route and an interruption in the operation of the
- the object of the present invention is to provide a generic stacking device with which larger storage capacities can be achieved.
- the invention is based on the idea of using a curved transport path and a multiple deflection of the belts in order to achieve rollers in the region of the transport path, a secure mounting of the letters between the belts of the transport path, the free movement of the stacking mechanism being ensured in that the belts are arranged in the region of the transport path between the stacking surface and the deflection roller.
- the device according to the invention therefore has a stacking surface which has a horizontal concave curvature with respect to the transport route.
- the belts in the region of the transport path are deflected by a number of deflection rollers which are arranged on a curve adapted to the curvature of the stacking surface in such a way that the transport path has a curvature which is essentially adapted to the curvature of the stacking surface, the belts in the region of the transport path are arranged between the stacking surface and the deflection rollers.
- the stacking surface is essentially ring-shaped.
- the stacking surface consists of a number of segments or is designed as a rigid disk.
- An embodiment of the invention is particularly preferred in which belt bridges are provided on the stacking mechanism and at the entry point, via which the outer belt is guided over or under the transport path.
- the two belts are common over the same pulleys, which also by the Transport route are used, or via additional deflection rollers arranged in the interior of the ring formed by the transport route.
- the device consists of a number of segments of the same type with the exception of the area of the input point and the separating mechanism.
- FIG. 2 shows a detailed view of the transport route 9 from FIG. 1,
- FIG. 3 shows a device according to the invention with a curved stacking surface
- Fig. 7 shows an alternative belt guide in an inventive
- Fig. 8 shows a ring buffer with segments.
- the stacking mechanism 2 can be moved in the stacking direction.
- the bottom of a stack of mail items is formed by a stacking surface 4, preferably designed as a rotating conveyor belt.
- Two endless belts 5, 6 run on rollers. They form a transport path 9 between an input point 100 and the stacking mechanism 2.
- the belts 5, 6 are freely guided between the roller 7 arranged on the stacking mechanism 2 and the stationary roller 8.
- the stacking mechanism 2 also has other rollers over which the belts 5 and 6 are guided in order to ensure that the mail items are securely stacked.
- the stacking mechanism 2 is moved in the direction of the stack 3.
- the length of the transport path 9 depends on the respective position of the stacking chanism 2 It shortens as the batch of items grows. Conversely, it reaches its maximum length when there is no stack of mail items and the stacking mechanism 2 is located directly on the separating mechanism 1. As shown in Fig. 2, in the case that a thin one is contained in the transport path 9 between two thick mail items, the thin mail item is not securely gripped by the belts.
- Fig. 3 shows the basic structure of a device according to the invention with a curved stacking surface 40, which serves as the floor for the stack of letters.
- the stack of letters is located between the separating mechanism 1 and the stacking mechanism 42. The latter can be moved along the stacking surface 40.
- the two belts 5 and 6 are guided over a number of rollers 45 and form a curved transport path 43. In the area of the transport path 43, the belts are deflected several times around the rollers 45. The distance between the roles is chosen so small that the letters are safely grasped.
- the deflection rollers 45 are all arranged on the same side of the pair of belts 5, 6 in the region of the transport path, so that the length of the transport path can be changed continuously when the stacking mechanism 42 moves along the stacking surface 40.
- the entire device of Fig. 3 is curved, i.e. Stacking surface 40 and the curve on which the deflection rollers 45 are arranged are matched to one another.
- the stack 41 and the path of the stacking mechanism 42 follow the curvature of the stacking surface 40.
- Fig. 4 shows an advantageous embodiment of the device, in which it is essentially annular. Due to the annular shape of the arrangement, the endless tracking of the belts 5, 6 is simplified by returning the outer belt 5 and the inner belt 6 in the areas 50 and 51 between the input point 101 and the stacking mechanism 42 in a short way.
- the inner belt 6 is preferably returned via a stationary deflection roller 53 which is arranged in the area of the input point 101 on the concave side of the curved stacking surface 52.
- the outer belt 5 is guided over the belt by two belt bridges.
- Fig. 5 shows a first belt bridge 60, which is preferably rigidly connected to the stacking mechanism 42.
- the belts 5 and 6 are guided over a number of deflection rollers, the outer belt 5 being rotated or turned back by 90 ° in its orientation by two horizontally positioned rollers 63, 64.
- the belt 5 can be guided both above and below the transport path 43.
- FIG. 6 shows a similar belt bridge 61 for crossing the transport route in the area of the entry point 101.
- the belt bridges enable the outer belt 5 to be guided back on the concave side of the stacking surface 52.
- the outer belt can therefore be returned together with the inner belt 6 between points C and D, via the same deflection rollers that also come from the transport path are used, and the deflection roller 53.
- FIG. 7 shows an advantageous embodiment of the invention, in which the belts 5, 6 are returned on additional deflection rollers. These deflection rollers are essentially arranged on a ring 70 which is located within the transport path 43. This arrangement enables the replacement of the endless belts 5, 6 even in the case when the entire device is e.g. B. is set up around a pillar.
- FIG. 8 shows a preferred embodiment of the device which is made up of a number of segments 81 of the same type, with the exception of the area of the input point and the separating mechanism 80.
