The invention relates to a method and an apparatus for consumption-dependent, continuous Allocation of goods to several processing and processing points, in particular for loading Cigarette machines with cut tobacco.

In a known method for forming a continuous stream of material from portions supplied material, the system is designed so that the incoming material flow over in the direction of travel Conveyor belts overlapping each other like scales are delivered to distribution devices that carry the material Evenly distribute them to special feed conveyors, with these feed conveyors being those downstream of them Supply finishing machines. The even distribution of the goods can be seen in the known methods can only be achieved by temporarily changing the conveying direction of the conveyor belts, namely through periodic changes in the conveying direction of these belts. This not only has the consequence that the incoming goods can only be delivered to a specific processing point, when the direction of rotation of a conveyor belt has been changed. but it occurs at the same time that the processing point receives a good delivery from two points. Furthermore, in the known Process provided that the belts should temporarily rotate at different speeds, depending on the needs, d. H. on the number of working processing machines. By changing the speed of rotation of the belts, funding gaps are compensated.

The invention has a further embodiment of the method and a device for consumption-dependent Distribution of the goods to any number of processing points related to the object. she draws is characterized by the fact that the successive delivery of the goods to the individual loading and processing points thereby predetermined time intervals with constant conveying direction be observed that the goods are not fully accepted at a processing point during the for the position remaining time is promoted to a common storage device and after expiration the rest of the time, the next processing point is supplied on time. When filled Storage, the delivery of the storage containers is interrupted and the goods from that Memory fed to the processing and processing points until the memory is emptied.

In this way it is achieved that the once defined work cycle for the individual

work stations can be precisely timed. What is not needed at a point of need is automatically transferred to the intermediate storage unit via the subsequent belts or transport devices and only until there is time to cover the demand at the next processing point has come up. The fact that, as soon as the buffer is filled, a switchover takes place in the system, so that only the memory is emptied, from the storage tank no new good is supplied, the result is that the good located in the intermediate storage does not last too long stored, but is completely delivered to the processing machines in a short time. the As a result, there is a risk of the condition of the goods located on the temporary storage deteriorating switched off.

The device according to the invention is characterized in that the at the branch points used to bridge the conveyor belts for the goods to be delivered to the processing points Intermediate members are designed as flaps that remove the material from the higher end of the preceding Conveyor belt in one position to the lower beginning of the downstream conveyor belt and lead in the other position to the processing or processing stations, and that in the feed of the goods to the processing point serving flap position the following conveying devices are stopped. At least one can be attached to the successive conveyor belts

Connect another conveyor belt serving as a memory, which is directly or indirectly to the first Feed conveyor leads.

The method according to the invention is explained with reference to the embodiment shown in the drawing.

Fig. 3 illustrates a section along the line 3-3 of Fig. 1 on a larger scale.

From a storage depot, which is embodied in the present case by the three containers 1, 2 and 3, the bottom of which is designed as a conveyor belt, conveyor belts 4, S and 6 lead to a feed device, which consists of several conveyor belts 7, 8, 9, 1 © exists. Flaps 11, 12, 13 are provided between these individual conveyor belts. In one position of the flaps, they bridge the distance between the adjacent conveyor belts. In the other position of the flaps, the goods can fall onto the conveyor belts 14, IS, IS, which lead to the consumption points, which are shown in the exemplary embodiment as loading tables 17, 18, 19. To ensure that the material is fed to the belts 14, 15, 16 in a uniform thickness, a swiveling funnel 20 can be provided in the space below the flaps 11, 12, 13, which constantly moves back while the belt 14, 15, 16 is being loaded. and is moved. The last belt of the feed system, for example the belt 1 ©, is followed by a further conveyor belt 21, which can be supplemented by a further conveyor belt 22, which returns the goods to one of the first conveyor belts 4, 5 or 6. In the present case, it is returned to the conveyor belt 6. The conveyor belts 21, 22 serving to return excess quantities also represent storage devices for any excess quantities that have not been removed at the delivery points, namely at the removal belts M, 15, 16. With a photo cell 23 is referred to, which controls the filling of the storage tape 22, which temporarily absorbs excess quantities. The illustrated embodiment deals with the loading of cigarette machines with cut tobacco, but can also be used in other areas. The system according to the invention is designed in such a way that each loading table 17, 18, 19 is fed exactly the amount of cut tobacco corresponding to the actual consumption at all times. This means that the amount withdrawn from the storage containers 1, 2, 3 must correspond to the maximum possible amount in order to be able to meet every need that may arise.

Normally an oversupply is to be expected, which is not taken up by the loading tables becomes and remains unused. This excess amount is for a new supply to the To keep loading tables ready or to bring them back to the store. The storage container 1, 2, 3 are designed in the present case so that they are either filled or emptied. A simultaneous Filling and emptying is not provided. For this reason, according to the invention Excess quantities stored independently and returned to the work process at a given time fed.

This results in the solution to the following partial problems:

a) Formation of tobacco portions according to the actual consumption at the point of consumption,

d. H. of the loading table.

b) Forming the portions into continuous streams of tobacco for non-stop feeding of the Tables.

c) Intermediate storage of the excess quantities.

When solving sub-problem a) relating to portion formation, it is assumed that each cigarette machine in operation a constant quantity of cut tobacco per minute in the running time needed. It is therefore only necessary to determine the number of running machines for each loading table in relation to the total number of connected machines. One with a relay combination Equipped counter provides exactly this information.

Table IS 6 machines

Table 19 6 machines

A total of 18 machines installed

4 machines are running at table 17

6 machines are running at table 18

5 machines are running at table 19

So there are currently 15 machines running

be given the total tobacco Quantum, and _^3/18 is stored in the cache. It is assumed for this example that the dispensing cycle is 1 minute = 60 seconds, ie that after this cycle the portion dispensing starts again at table 17:

With all 18 machines running at full capacity, 45

Table 17 from the 61st to 80th second Table 18 from the 81st to 100th second Table 19 from the 101st to 120th second, etc.

But now that machines have failed, we will

charged and the excess amounts in the 14th to 20th second and in the 58th to 60th second

saved.

This method, which is proportional to the number of pieces, with the time d. H. quantity-dependent loading is each table is supplied with a quantity of tobacco that corresponds exactly to its consumption.

With regard to the transformation of the portions into continuous streams according to sub-problem b), the according to the method described above, portions formed as a function of consumption are continuously fed to the loading tables. The solution provides an intermediate belt 14, 15, 16 which carries out this reshaping.

The tobacco quantities delivered by a conveyor belt 7, 8, 9 via a switchover flap 11, 12, 13 are evenly distributed by a swivel funnel 20 on an intermediate belt 14, 15, 16. The feed speed of the intermediate belt is constant. So the thickness of the layer formed is since the length and width of the shift remain constant, it is directly proportional to the duration of the allocation (constant Supply quantity assumed). The transfer to the loading table takes place continuously. Because the layer thickness corresponds to the loading time and this depends on the number of consuming machines the tobacco allocation in each case exactly to the consumption amount.

With regard to the intermediate storage of the excess quantities according to sub-problem c), this is in practice to be expected that excess quantities, which with regard to a secured under all circumstances Supplies are necessary, must be stored.

The memory 21, 22 provided for receiving these quantities is made up of the partial quantities produced filled evenly until its capacity is exhausted. He then interrupts the other Tobacco supply from the storage containers 1, 2, 3 and takes over at the same moment as long Supply of the loading tables until its content is used up. Then he switches back to the depot, and the game starts all over again.

The system works as follows:

From the storage containers 1 or 2 or 3, the tobacco reaches the conveyor belts 4, 5, 6 Volume 7. The flaps 1.1, 12, 13 are in the rest position, so that the further path of the tobacco is given via the bands 8, 9, 10 to the memory 21, 22. All bands 8, 9, 10 and 21 are even filled with tobacco. The tape 22 as storage is ready to receive; H. empty.

The loading cycle begins with the flap 11 pivoting back, i.e. H. Pivots to the left in the plane of the drawing, causing the tobacco to appear the intermediate belt 14 arrives. The belts 8, 9, ίΟ and 21 remain laden with tobacco. Also the Memory 22 is standing. After the loading time has elapsed, the flap 11 swivels into the starting position back and tapes 8, 9, 10 and 21 are running again. When switching the flap 11 before If the maximum possible time has expired, tobacco is first stored in the store 22. if the maximum has been reached, it switches with a return movement the flap 11, the next following flap 12 on the loading of the table 18. Remain here the belts 9, 10 and 21 stand until the return of the flap 12 takes place. This game repeats itself with the next following flaps 13, etc. After the complete cycle has expired, the first one follows again Flap 11 with the loading table 17 and so on.

The result is that tobacco only gets into the 6g storage tank 22 when excess quantities are available due to failure to utilize the maximum charging time provided for a charging tray, which cannot be immediately supplied to one of the consumption points 17, 18, 19, etc. When the memory 22 is full, which is monitored by a photocell 23 or the like, which also gives the message for emptying, the storage containers 1, 2, 3 and the conveyor belts 4, 5 are stopped. The storage belt 22 with the belts 6 and 7 takes over the supply of the consumption points 17, 18, 19.

When tobacco is delivered from the store 22, the tobacco delivery of which, in contrast to the delivery from the storage containers 1, 2, 3 suddenly stops at a standstill, only that amount is delivered that is consumed at the consumption points 17, 18, 19, so that a repeated There is no storage of excess quantities. This has the consequence that the following conveyor belts stop in the starting position of the flaps and only run in the working position. When the storage tape 22 is emptied, the forward movement on this tape ceases. For this, the transport from the storage containers 1, 2, 3 and the movement of the belts 4, 5 are switched on again, so that the process is carried out again as normal. By stopping the belts 8, 9, 1 ©, and 22 during the transfer to the previous consumption point 17 when loading from the depot or by stopping the belts 4, S and 8, 9, 10 and 21 when loading the memory 22 ensures that the tobacco flow on these belts is not interrupted and that the full quantity is immediately available at any time when a request is made by the consumption points 17, 18.
