The invention is based on a multiple switch for the optional supply of flat conveyed goods, such as mail, in one of several conveyor channels arranged next to one another, the walls of these conveying channels being attached to and with the switching elements of the switch these pivotable foils are formed.

Multiple switches of this type have already become known. In such a switch are z. B. four Foils are attached to four horizontally arranged bars and form a total of five conveying channels, in which the conveyed item, in this case mail, is distributed through the switch and then its is fed to different destinations. By swiveling one or more of them sideways which in the idle state all bars lying next to each other on one side of the feed conveyor channel a second end position located on the other side of this feed conveyor channel becomes the selected one Conveying channel open for the conveyed goods fed in from above. This sideways moving or Moving the individual rods is done via a pivotable lever on the axis a rotary magnet is arranged. In order to achieve short response times - which means that the Inertia of the masses to be moved is small - are the rods and in this known device Lever built very light. However, this known device has several significant disadvantages. When a mail item entered a conveying channel, the foils forming the side walls Forces exerted on the rods and levers in question, which due to the light construction this Set elements vibrating. Such vibrations, however, increased operational safety the switch is not insignificantly reduced. Furthermore, due to its light construction, the if the levers hit their stops, strong bouncing vibrations in the jacks and rods. and Finally, with this known switch it often happened that mail items with deformed leading edges were not properly shot into the conveyor channel formed from the foils and instead hit one of the bars. This resulted in blockages through which the shipments concerned were badly damaged and in some cases the switch was made unusable.

The object of the invention was to avoid the disadvantages of the known switch and to provide a device to create which with the same or even shorter turnaround time a considerably larger one Has operational reliability. Based on a multiple switch

Multiple points of the type described above, the invention is seen in that, that the films on free end each of a pivotable arm in one of two end positions are attached, the The pivot axis runs parallel to the conveying direction. This training according to the invention takes place a separation of the storage and propulsion of the

as the foil-carrying arms. There Now the storage of the arms can be done a lot easier than before - all arms are around either a single axis of rotation or around several axes of rotation running parallel at a short distance from one another pivoted - and thus the previous levers are omitted, the arms can be designed to be more stable than before without increasing the inertia of the system. Also, this has inventive training the advantage that the arms can absorb much higher forces than the Bars of the well-known multiple switch.

By an advantageous development of the device according to the invention, according to which the arms as Plate-like wings are formed, the arrangement is largely free of bouncing because before the collision of two wings when switching the switch first the air between the wings must escape and the impact is very dampened as a result.

An expedient embodiment of the invention is that the pivot axis of the arms is vertical runs and the foils are attached to the wings hanging vertically, the wings either a downwardly open U-shaped cross section along a sectional plane perpendicular to its longitudinal axis or have a stiffening kink or the like in their longitudinal axis.

In the drawing, an embodiment of the training according to the invention is shown. It shows

1 to 4 denote two pairs of transport rollers which, together with the inlet funnel formed from the plates 5, 6, form the inlet conveyor path for the material 7 to be conveyed. The actual multiple switch is arranged downstream of these transport rollers on the conveying path in the downward direction a bearing block 12 4EmIt are clamped so that they can be swiveled horizontally, in the rest position of the switch, the two outer wings -8 and 10 lie against two plate-like stops 13, 14, while the two inner wings 9 and 11 are flat against the two outer ones Wings S and

10 are present. On each of these wings 8 to 11, namely at the free end, a thin plastic film 15 to 18 hanging down from the wing is attached, with two be-Jaaehbaite JKjansistoJMien: zor formation of a conveyor channel. All four plastic foils are brought together in a common line below the switch at the area of two transport mUsmpaavsn 19 to 22 so that the conveyed goods located in any of the conveying channels are conveyed away by the transport rollers 19 to 22 '. Below these pairs of transport aslias - possibly at a large distance from the latter and therefore no longer shown in the drawing - the plastic foils open into fixed conveying channels in which the conveyed goods are fed to their destination. With 23 to 26 four rotary drives are referred to, which zmm pivoting of the wings 8 to 11 are used. On the axes of JDnehraagneten are arranged üebel 27 to 3Θ, "which are provided at their free ends with rollers 31 until the 34th Each of these grooves cooperates with ije ernenn connector .35 to 38 together, the in each case one of the FJäigel to S

The connecting pieces 35 mad 36 of the two inner wings 9 and 11 protrude through corresponding openings in the outer wings S and 10 to the outside. In order to keep the rollers 31 to 34 with the corresponding Verbmdnngsslüäken frictionally connected to each of the levers is mounted 27 to 30, a tension spring 39,40 - the other two are not visible .Zugfedern - which .ortsfesten at its other end to a Frame piece 41,42 is attached. In order to bring one of its pivoted wing back into its starting position from its one end position (rest position), a tension spring 43 '44 is attached to each of the connecting pieces 35 to 38, which is also fastened at its other end to the frame pieces 41, 42 These last-mentioned springs, which have a stronger tensile force than the first-mentioned, must be dimensioned in such a way that on the one hand they can quickly bring the swung-out wing back into its starting position, but on the other hand do not oppose too much force to the rotary magnet during the swing-out process, otherwise this swing-out process will not is completed in a sufficiently short time.

ίο The operation of the device is briefly as follows: In the rest position of the switch there are two wings on one side and two wings on the other side in their respective end positions. The conveying channel, which is formed by the plastic films 17 and 18, is released for the entry of one or more successive mail items. If, for example, a mail item is to be channeled into the conveying channel formed by the plastic films 16 and 18, then the wing 11 with its plastic film 18 is pivoted into the other end bracket by adjusting the rotary magnet 26, where it comes to rest on the wing 9. If next, for example, a mail item is to be introduced into the conveying channel formed by the plastic films 15 i and 17, the wing 11, after the rotary magnet 26 is no longer excited, is brought back to the starting position and the wing 9 is brought back to the starting position by exciting the rotary magnet 25 pivoted in the direction of the stop 14, where it comes to rest the wing 11. The desired conveying channel is created through these movements. By simultaneously pivoting the wings -8 and 9 or 10 and 11 into the other end position, the conveying ducts are released for the conveyed goods, which are only covered by plastic foils on one side, namely by the plastic foils 15 and 16, respectively. A fixed guide wall forming the second side of the conveyor channel is assigned to these plastic films in an expedient manner after the pairs of transport tubes 19 to 22 - no longer shown in the drawing

The facility makes it possible to use selectively with little effort to create a functionally reliable and fast multiple woe, which, like * the The embodiment described shows that the conveyed goods can be distributed in a total of five directions.
