Object of the invention

It is an object of the invention to provide a conveyor for conveyable, which has a large capacity recording *, waiting times by the resulting ümladevorgänge to a minimum and by large shipping units, the resulting shipping costs low «

Explanation of the essence of the invention

The object of the invention is to provide a conveying device, which are used for quick compilation address equal conveyable to a shipping unit all stored on multiple storage and transfer devices conveyable one and the same address as possible gleichzei "tig loaded onto trolleys and itab3tänden in shortest possible Z _e transported to the collecting * Des Furthermore, by means of simply constructed memory and transfer devices, stored conveyed goods carriers should be able to be transferred in groups to a support bar of the trolleys, which run continuously.

According to the invention, this object is achieved in that a first circular conveyor is arranged for unoccupied trolleys, the rails start along delivery ends of the receiving elements and said circular conveyor is connected by switches with a second K _r eisförderer whose rails arranged along the secondary lines of the collection point are*

Since in the region of the delivery ends of the receiving elements extending first circular conveyor are only unloaded and therefore always receptive trams, the transfer of stored on a receiving element ^ on

According to a further proposal of the invention, the recording elements of the storage and transfer devices are formed by worm shafts in whose helically extending hat the suspension members of the conveyable goods carriers are arranged.

Another proposal of the invention is that each switch is associated with a Hebenforderer, which is designed as a circular conveyor with known switchable as Mitnahnievorrichtungen formed couplings for the tram »A discharged by means of a Y / oak from the first circular conveyor loaded trolley is thus initially taken from the secondary conveyor and stored at its discharge end with uncoupled driving device (clutch) until it can be passed to a free driving device of the second circular conveyor »Conveniently set up for the simultaneous recording of several trolleys secondary conveyor forms in this way a buffer line between the first and second circular conveyor of the conveyor ", The secondary conveyor therefore allows the discharge of several trolleys from the first circular conveyor even then an undisturbed circulation of the remaining in this circular conveyor Tram if the second circular conveyor can not immediately take over all the trolleys that have been removed. «

For re-entraining unladen tram from the second in the first circular conveyor is another Ue- "benförderer, which is also designed as a circular conveyor with known switchable designed as driving devices clutches" This second secondary conveyor is also suitably for receiving several,

The collection point 50 consists of several, for receiving trolleys 25 serving drive-free sexes 68, which are connected by means not shown switchable points with the Latifschiene 24 'of the circular conveyor 72.

The conveyor works as follows:

At a loading point A of the circulating hanger conveyor 1 hanging on a hangers 4, provided with a customer address Fördergutstücke successively passed to the steadily driven circulating hanger conveyor 1, in each case only a hanger 4 is mounted in a holding device 10, When hanging a hanger 4 in the holding device 10th a combination of target identifiers corresponding to the customer address is set at the destination identifier carrier arranged on the holding device 10 *

The holding device 10 loaded with a clothes hanger 4 now runs through the discharge station 20 of the circulating hanger conveyor 1 # As soon as the holding device 10 approaches a discharge station 20 whose drawing control device responds to the target recognition oak stored on the target identification carrier of the holding device 10, the switching strip 21 is in the working position emotional.

associated worm shaft 13 · The hook 5 of the hanger 4 is thereby received in the worm groove 17 ·

After receiving the hanger 4 in the worm groove 17, the brake motor 16 performs a full revolution of the worm shaft 13, whereby the hanger 4 is moved by the amount of the pitch of the worm groove 17 away from the task end 18 in the direction of the discharge end 19. As a result, the section of the screw groove 17 lying below the end of the slide rod 22 is free for receiving a further coat hanger 4.

The target control device of each discharge station 20 causes only hangers 4 are conveyed with Fördergutstücken the same address on a certain worm shaft 13. Therefore serve the worm shafts 13 of the bearing 2 for address sorting of conveyed in any order to the TJmIaufhängeförderer 1 Fördergutstücke. Since each worm shaft 13 performs a full rotation after receiving a hanger 4 while transporting the clothes hanger 4 located on the worm shaft 13 by a pitch corresponding to the pitch of the worm groove 17 in the direction of the discharge end 19, a larger number of hangers 4, each equal large mutual distance on the worm shafts 13

The length of the worm shaft / ?. 13, for example, be dimensioned such that the storage capacity of hangers 4 of the worm shaft 13 and the support rod 27 of the trolley 25 is the same »as shown in Figure 3, but» can also longer worm shafts. 13 are used, where «

due to the storage capacity of the worm shaft 13, the holding capacity of the support rod 27 exceeds twice or several times.

As soon as the foremost coat hanger 4 has reached the discharge end 19 and thus the worm shaft 13 is fully loaded, it is prevented by known and therefore unspecified circuit measures that further hangers 4 are dropped on the affected worm shaft 13. The clothes hangers 4 which can no longer be released to the fully loaded worm shaft 13 are now delivered to the next still unoccupied worm shaft 13 of the bearing 2. In this way, it is possible that at a storage capacity of a screw shaft 13 exceeding number of Fördergutstücken same address two or more screw shafts 13 are loaded with Fördergutstücken one and the same address.

If now all conveyed items stored on different screw shafts 13 are to be transported to the collecting point 50 in order to combine them there to form a shipping unit, then the hangers 4 carrying the items to be conveyed must first move from the screw shafts 13 to the trolleys circulating in the conveyor loops 51 f 52 25 reloaded.

Before starting the reloading or transfer process, the loading state of the trolleys 25 passing the respective auger shafts 13 must first be checked by means of known and therefore unspecified, for example mechanically or optically operating detection devices.
