Description

The invention relates to a conveyor system for conveying containers, in particular a box conveyor system, with a Circulating elevator serving several floors, the one for storage and controlled delivery of empty ones Conveying containers serving central storage is assigned.

The German patent specification 1 142 793 describes an arrangement for supplying the stations as required known in pneumatic tube systems with cans, but which can also be used in box conveyor systems which a central memory is provided to which the cans not directly required by the individual Pneumatic tube stations are fed. Is used at one of the pneumatic tube stations to carry out a The conveying process requires a liner, an incentive must be activated manually via appropriate switching means of the central memory, which then prepares the path to this requesting station and releases a can from memory. From the moment such a rifle is released to their arrival at the requesting pneumatic tube station is the one switched through from the memory to the station Conveying route - taking into account that the memory is connected to a fully automatic pneumatic tube system usual central multiple switch is connected, so that of the pneumatic tube station in question assigned receive line, blocked for any further traffic. Funding processes, the pneumatic tube carriers imply with goals belonging to the relevant reception strand, so must be before the Release of the rifle from the central memory has already ended or has been forcibly interrupted. the Covering the need for empty pneumatic tube carriers of the individual pneumatic tube stations thus affects the in the pneumatic tube system running conveying processes, so that by the arrangement and operation of a such a central memory overall impairment of the traffic performance takes place. Since the Speed of pneumatic tube carriers, especially empty pneumatic tube carriers, is relatively high and in so far waiting times should be short, but also due to the fact that in such fully automatic pneumatic tube systems use the central multiple switch and not any other internal ones If blockages limit traffic performance, this impairment is considered irrelevant in practice to watch.

The situation is different in the case of circulating elevators in conveyor systems, since the speed in these is the same the receiving organs and thus the conveying container significantly smaller than the speed of pneumatic tube carriers and no increase in the speed of empty containers compared to that of loaded containers occurs. Traffic restrictions of the type described are therefore likely when using of circulating elevators in conveyor systems can take on disruptive proportions.

The object on which the invention is based is, if possible, at each sending station to enable quick access to empty conveying containers, without increasing the transport performance of the conveyor system and in particular that of the circulating elevator affect. This object is achieved according to the invention in such a way that in each floor to Storage of a predetermined number of conveying containers storage locations are arranged, which have a Floor distribution control assigned to each floor and a central distribution control with the central one Memory are linked, and that when a conveying container is requested in one of the floors, the central Distribution control can be influenced by the associated floor distribution control in such a way that the central Distribution control when there is at least one empty conveying container in the central memory The introduction of such a conveying container from the central store into the circulating elevator causes j and stimulates switching measures in the floor distribution control of the relevant j floor, which either the Removal of the from the central storage in the; Circulation elevator smuggled conveying container into the the respective floor or, if there are several empty conveying containers in the circulating elevator, the discharge of the conveying container closest to the floor in question to the floor in question.

As essential to the invention that \ the actual storage of empty transport container is carried out individually floor and in that, as it were acting as a regulator, a central store all floor individual memories is additionally assigned is considered. The functional linking of the storey-specific storage spaces with the central memory takes place via the storey-specific storey distribution controls, which are linked to the central distribution control in such a way that a bilateral flow of information is possible. After removing a conveying container from a storage space on one of the floors, the corresponding floor distribution control is automatically influenced, which then initiates the transfer of a conveying container from the central memory or from the circulating elevator to the relevant floor via the central distribution control. It is also essential that the empty conveying containers not required in the floors are channeled into the circulating elevator and, if there are no requirements from conveying containers in the other floors, are transferred to the central memory without prior setting of a corresponding target identifier. If conveyor containers are requested on the individual floors, the conveyor containers that are not needed in the circulating elevator remain in the circulating elevator until the switching measures for introducing the conveyor containers into the respective floors have been carried out. After the request for a conveying container in one of the floors, the conveying container that is closest to the floor, as seen in the direction of travel of the circulating elevator, is channeled into the same. If the circulating elevator is additionally used as a store for a certain number of empty conveying containers, the conveying containers that would otherwise be discharged from the circulating elevator into the central memory are only prevented. This enables even better utilization of the conveying containers present in the conveying system.

An expedient implementation of the actual discharge process takes place through the use of means known in box conveyor systems. In the known box conveyor systems, the conveyor containers carry Target identification, the scanning devices arranged on the floors in the area of the circulating elevator affect, which in turn when the target identifier matches the identifier of the Swivel flaps provided with rollers into the area of the conveying container and thus prevent it from continuing to travel in the circulating elevator. The hinged flaps have

preferably one in the direction of the laxative Belt inclined position so that the conveying container under the action of gravity without an additional Drive the drive into the area of the floor.

Overall, the claimed linking of storey-specific storage spaces with a central storage via floor distribution controllers corresponding to a central distribution controller achieves that when the memory is not completely filled or, if necessary, a larger number of conveying containers than the number of available storage locations, immediate or at least one accelerated access to empty conveying containers is possible without manually initiating any switching measures would have to be.

From the German patent specification 952 338 it is known, depending on the filling level of several receiving memories To distribute letters from a central store to this receiving store. From the German Patent specification 1157 144 is also the automatic filling of storage sections in box conveyor systems in Known as a function of the filling level of the storage sections. However, these arrangements are insofar not comparable with the subject matter of the invention, as with them only one type of conveyed goods, namely to sorting letters or similar conveyor boxes, are transported in the conveyor system while moving in the system according to the invention in addition to loaded conveying containers and empty conveying containers in one Conveyor system are located and constant access to empty conveying containers without affecting the Funding of filled conveying containers can be carried out.

The in the F i g. 1 to 6 illustrated embodiment of a conveyor system according to the invention described below. It is assumed that the conveyors are empty boxes.

Fig. La, Ib, Ic show a schematic representation, partially sectioned, of a rotary elevator serving three floors ET1 to ET3 in three views. Storage spaces Wl to WlS for empty bins are located on the three floors ET1 to ET3. Furthermore, FIG. 1 in the individual floors in block diagrams distribution controls : for the floor ETl the floor distribution controller EVS1, for the floor ETI the floor distribution controller EVS2, for the floor ET3 the floor distribution controller EVS3 and the central distribution controller ZVS as well as the circulation train monitoring UAU. The storage locations Wl to WA together with the central distribution control ZVS form the central storage ZSP.

F i g. 6 shows the circuit diagrams of the storage locations WS to WS of the floor ET1 .

In the exemplary embodiment according to the invention, the central distribution control Z VS with the storage locations Wl to WA and the circulating elevator monitoring UA Ü are located on the floor ET3.

According to FIG. 1, two elevator chains 1 and 2 are arranged in the elevator shaft of the circulating elevator, which are deflected via gears 5, 6, 7, 8, 9, 10, 19 and 20. The two elevator chains 1, 2 are arranged offset. Carrier frames 3 are attached to them at the same distance so that two diagonally opposite corners of the four corners of the carrier frame are connected to the two chain strands of the elevator chains that move up and down. In the elevator shaft, pivot flaps 11,13,15 provided with rollers 12,14,16 are arranged at the level of the individual floors ET1 to ET3 , which are used to divert empty boxes from the circulating train into the individual floors and from the individual floors into the circulating elevator. Two conveyor belts are provided on each floor outside the circulating elevator. One conveyor belt leads to the upward moving carrier frame of the circulating elevator, while the other conveyor belt leads away from the downward moving carrier frame of the circulating elevator. On the conveyor belt of the individual floors leading to the upward moving carrier frame, empty boxes are brought into the circulating elevator in a manner not shown. Storage spaces that store empty bins are shown schematically in the individual floors, namely storage spaces WZ to WS on floor ETl, storage spaces W9 to WlA on floor ETl, storage spaces W15 to WlS and storage spaces Wl to WA of the central one on floor ET3 Memory. The storage locations W5, W9 and W15 have mechanically operated contacts vk5, vk9 and vkl5 , the contact vk 5 being connected to the floor distribution control EVSl, the contact vk9 with the floor distribution control EVSl and the contact vkl5 with the floor distribution control EVS3 . The storage space WA of the central store has a mechanically actuatable contact vkA which is connected to the central distribution control ZVS . The floor distribution controls EVSl and EVSl and EVS3 are connected to the central distribution control ZVS of the floor ET3 . Empty boxes to be brought into the circulating elevator from the individual floors are channeled into the upward moving carrier frame via the pivoting flaps located on the floor concerned. An empty box to be ejected from the circulating elevator in one of the floors is lifted out of the downward moving carrier frame by means of the swivel flaps. In the elevator shaft of the elevator circulating Bl to B3 are disposed so that the downwardly moving empty crates these press during their downward movement above the individual floors ETL to ET3 sensing.

According to FIG. 2 conveyor belt leading to the circulating elevator is not shown further. From the downward moving carrier frame of the circulating elevator , a conveyor belt leads to the storage locations W9 to WIl and another to a destination station ZSTl, at which two storage locations W13 and WlA are arranged. On space W13 a TasteTl and the space WLA Tl key is provided. Both buttons are connected to the floor distribution control EVSl . The scanning element Bl is also connected to the floor distribution control EVSl . A mechanically actuatable contact ekl is provided in front of the fork of the two conveyor belts. The arrangement of the two conveyor belts with the corresponding storage spaces on the ETX floor is the same as in FIG. 2, with the only difference that no storage locations are provided at the destination station ZST1.

The partial section from the circulating elevator according to FIG. 3 at the level of the floor ET3 shows the chain strands 1 and 2 moving up and down. To the side of the chain strands connected by the driver frame 3 there are deflector flaps 15 and 15 a or 156 and 15c. The deflector flaps 5, 15 a, 15 b and 15 c have driver rollers 16, 16 a, 166 and 16c.

The floor distribution controls EVSl, EVSl and EVS3 have according to FIG. 4 mechanically operated contacts 12vk5, IWc 5 of the storage space WS, 13 Wc 9, 2vk9 of the storage space W9, 14v / cl5 and 3 We 15 of the storage space WlS . Scanning contacts 141621, 142611 of the contact element B1, 144622, 145612 of the contact element U2, 147623, 148613 of the contact element 53, which can be actuated by the empty boxes, are connected to storage means S1 to S5. Latch relays are used as storage means. Switching means El to £ 3 form a search chain which is influenced by a test means P arranged in the central distribution control ZVS . Relays are used as switching means. The scanning devices Jl to / 3 provided for the individual floors, which cause empty boxes to be discharged from the circulating elevator, are influenced by control devices β 1 to Q 3. Relays are used as scanning devices and control devices. The mechanically actuatable contacts 12 vk5, Ivk5 of the storage space W 5, 13 Wc 9, 2 Wc 9 of the storage space W9, 14 Wc 15, 3v / cl5 of the storage space W15 are connected to request means Kl to KA and ANl to AN3 . The above-mentioned mechanically operable contacts are shown in the working position, ie the storage locations WS, W9 and WIS are occupied by empty boxes.

The central memory ZSP according to FIG. 5 shows the memory locations Wl to WA with the magnets ^ 4AfI to AM 4 and the mechanically actuatable contacts 4 vk 4 to 11 WcI drawn in the working position and a central distribution control ZVS with a forward and backward counting chain ZAK, which is controlled by the control means PL and M is influenced. A scanning device Jo which can be influenced by the scanning element B3 is provided in the central distribution control ZVS. This scanning device is a relay. The central memory ZSP also has a circulating elevator monitoring UA Ü which contains counting devices ZElfll, ZZlIIl, ZK ψϊ . The counting devices ZE, ZZ and ZK are counting magnets with ten armatures each, which respond one after the other according to the number of pulses they generate. The second windings of the counting magnets cause the armature to drop into its rest position. The counting magnets act on switching devices X, ZHl, ZHl, which influence the control means PL and the response circuit of the scanning device Jo . The counting magnets ZE, ZZ and ZK are z. B. in the floor ETl is affected frame contact 176 rk. If the circulating elevator is used to store the empty boxes, the empty boxes to be stored in the circulating train have to be counted anew with each revolution of the elevator. This is done via the scanning element B3. After one full revolution, the armatures of the counting magnets ZE, ZZ and ZK fall into their rest position.

The circuit diagram according to FIG. 6 of the floor ET1 shows the storage locations WS to WS with the lifting magnets AM5 to AMS. The memory locations are connected to one another via the mechanically operated contacts 119vk5, 220 Wc 6, 212 Wc 6, 221Wc7, 213Wc7, 222v / c8. The memory locations W9 to WIl, WIS to WIS of the floors ET1 and ET3 are corresponding to the FIG. 6 built.
In the following three states are considered:

1. The storage locations Wl to WA of the central memory ZSP of the floor ET3, the storage locations W5 to W8 of the floor ETl, the storage locations W9 to WlA of the floor ET1 and the storage locations WlS to WlS of the floor ET3 are filled with empty boxes. An empty box is removed from the storage space WZ on the floor ET1, the storage spaces WIl and W13 on the floor ET1 and the storage space WlZ on the floor ET3. The removal of an empty box from the storage space WS or WIl or WlS automatically results in a request for an empty box in each case from the central memory ZSP for the storage space WS or W9 or W15 . By pressing a push button T1 of the memory location W13 , a further empty box is requested for this memory location. The request for empty boxes for the storage locations W13 and WlA is made by pressing the keys 7Ί and Tl and is independent of whether there are empty boxes in these storage locations or not. There is no empty box in the circulating elevator before and during the removal of the empty boxes from the storage locations WS, WIl, Wl3una WlS.

2. The storage locations IF1 to WA of the central storage facility ZSP are not occupied by empty bins. The storage spaces WS to WIS on the floors ET1 to ET3, however, are filled with empty bins. 14 empty boxes from the floor ET1 are fed into the circulating elevator , of which ten empty boxes are stored in the circulating elevator, while the remaining four empty boxes are to be transported to the central storage ZSP on floor ET3 .

3. The storage spaces Wl to WA of the central memory ZSP and the storage spaces WS to WIS on the floors ET1 to ET3 are filled with empty bins. Ten empty boxes are stored in the circulating elevator. While the fifth empty box is being counted, an empty box is removed from the storage location WS on the floor ET1.
