Description

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

The German patent specification 1142 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, moreover, 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 reducing the transport performance of the conveying system and especially that of the circulating elevator. This problem is solved according to the invention in such a way that in each floor for storing a predetermined number of conveying containers Storage spaces are arranged, each of which has a floor distribution control assigned to a floor and a central distribution control are linked to the central memory, and that on request of a conveying container in one of the floors, the central distribution control by the associated floor distribution control can be influenced in such a way that the central distribution control in the presence of at least one empty conveying container in the central memory, the introduction of such a conveying container causes the central storage in the circulating elevator and in the floor distribution control of the relevant

ίο floor switching measures that either the Removal of the conveying container from the central store into the circulating elevator 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.

It is to be regarded as essential for the invention that

the actual storage of empty conveying containers is carried out for each floor and that, in addition, Acting as a regulative, as it were, a central storage unit is assigned to all storey-specific storage units is. The functional connection of the storey-specific storage spaces with the central storage facility takes place via the floor distribution controls, which are also designed for each floor, with the central distribution controller are linked in such a way that a bilateral flow of information is possible. It will after removing a conveying container from a storage location on one of the floors, the corresponding one Floor distribution control automatically influences the transfer via the central distribution control a conveying container from the central store or from the circulating elevator to the relevant floor caused. It is also to be regarded as essential that the empty conveying containers that are not required in the floors be smuggled into the circulating elevator and if there are no requirements from conveying containers on the other floors without prior setting of a corresponding destination identifier in the central one Storage to be transferred. If there are requests from conveying containers, remain in the individual floors the unneeded conveying containers in the circulating elevator so long in the circulating elevator, until the switching measures for channeling the conveying containers into the relevant floors have been carried out. After the request for a conveying container in one of the floors, the conveying container is then placed in the same smuggled in, which is closest to the floor, as seen in the direction of travel of the circulating elevator.

With the additional use of the circulating elevator as a store for a certain number of empty conveying containers only the otherwise occurring discharge of the conveying container from the circulating elevator prevented in the central memory. This enables even better utilization of the in the conveyor system Allows existing conveying container.

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

The deflector flaps 15, 15 α, 15 6 and 15 c have driver rollers 16, 16 a, 166 and 16 c.

The floor distribution controls EVS1, EVS2 and EVS3 have according to FIG. 4 mechanically operated contacts 12vk5, Ivk5 of the storage location WS, 13vk9, 2vk9 of the storage location W9, 14vA; 15 and 3vä: 15 of the storage location W15 . Scanning contacts 141621, 142611 of the contact element B1, 144622, 145612 of the contact element 52, 147623, 148613 of the contact element 53, which can be actuated by the empty boxes, are connected to storage means 51 to 55. Latch relays are used as storage means. Switching means £ 1 to E3 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 71 to / 3 provided for the individual floors, which cause empty boxes to be discharged from the circulating elevator, are influenced by control devices 0 1 to Q 3. Relays are used as scanning devices and control devices. The mechanically actuatable contacts 12 vk5, Ivk5 of the storage space WS, 13vk9, 2vk9 of the storage space W9, lAvklS, 3vklS of the storage space WlS are connected to request means K2 to KA and ANl to AN3 . The above-mentioned mechanically operated contacts are shown in the working position, ie the storage locations WS, W9 and W15 are occupied by empty boxes.

The central memory ZSP according to FIG. 5 shows the memory locations Wl to WA with the magnets AMl to AMA and the mechanically actuatable contacts 4 vk4 to 11 vkl shown in the working position and a central distribution control ZVS with a chain ZAK that counts up and down and is influenced by the control means PL and M. . 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 ΖΕΙ / Π, ZZljll, ZKl [II] . 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, ZH2, 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 influenced frame contact 176 / 7c. 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 ETl shows the storage locations W5 to WS with the lift-off

magnets AM5 to AMS. The memory locations are connected to one another via the mechanically operated contacts 219V & 5, 220v / c6, 212Wc6, 221vkl, 213v / c7, 222v / c8. The memory locations W9 to W12, W15 to W18 of the floors ET2 and ET3 are corresponding to FIG. 6 built.
In the following three states are considered:

1. The storage spaces Wl to WA of the central memory ZSP of the floor ET3, the storage spaces WS to W8 of the floor ETl, the storage spaces W9 to WlA of the floor ET2 and the storage spaces W15 to WlS of the floor ET3 are occupied with empty boxes. An empty box is removed from the storage space WS on the floor ET1, the storage spaces W12 and W13 on the floor ET2 and the storage space W18 on the floor ET3. The removal of an empty box from storage space WS or W12 or WIS automatically results in a request for an empty box in each case from the central memory ZSP for storage space W5 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 T1 and T2 and is independent of whether there are empty boxes in these storage locations or not. Before and during the removal of the empty boxes from the storage locations WS, W12, W13 and W18 there is no empty box in the circulating elevator.

2. The storage locations W1 to WA of the central storage facility ZSP are not occupied by empty boxes. The storage spaces WS to WIS on the floors ET1 to ET3, however, are filled with empty bins. In the circulation elevator 14 empty boxes from the floor ET1 are smuggled, of which ten empty boxes are stored in the circulation elevator, while the other four empty boxes are to be transported to the central storage ZSP on the 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 circulation elevator. While the fifth empty box is being counted, an empty box is removed from the storage location WS on the floor ET1.
