Procedure and. Device for distributing goods to a number of receiving stations (addendum to patent 15 88 193.3)

The invention relates to an electrical control for a System for distributing material in a fluid circulation, such as a stream of air, suspended matter to any of several receiving stations at which there is a need this good prevails. More precisely, the invention relates to the conveyance of goods from several stores practically at the same time and in a variable amount to different pick-up stations depending on which one Storage for loading which pick-up station or stations is selected.

The invention can for example be applied to the distribution of materials as they are tet in textile plants processed%, that the distribution of fibrous or fiber-containing materials, such as cotton, rayon and dacron. However, the invention is not limited to the handling of the substances mentioned, but any other substance that is to be distributed by means of the system can also be handled without further ado. Any material that can be conveyed by a fluid flow, such as an air flow, can easily be distributed by means of such a system. Basically, however, the invention is not based on a negative pressure or the like. Fluidizing device limited. «2 -

For example, in textile mills there are often instances where it is deemed necessary to remove fibers from a processing system to convey to another, which is usually done by suspending the fibers in a stream of air he follows. In order to separate the fibers from the air flow at the discharge point, a "fiber condenser" is usually used. designated manifold pick-up valve device is used, for example, as in the United States patent 3 039 1 ^ 9 is described. Condensing apparatus of this type or other material separation or distribution devices can be arranged at the individual receiving stations on which the fibers are dependent of the material requirements of the relevant station are to be distributed. Such a condensation apparatus or distributor / collector valve assigns an air inlet and an air outlet duct in connection with a fiber outlet a hopper or the like provided at the relevant station. as well as a controllable buyer, for example in the form of a valve, for branching off the air and the in this suspended substance from the inlet channel and for dividing it to the air outlet channel or the Fiber outlet when the receiving station in question has a need for material. The inlet and outlet channels all distributors are connected to an air circulation system, the arrangement being such that the substance suspended in the air flow, if the pick-up of a receiving station is not actuated, on arrival sweeps past the relevant customer at this station and is conveyed to the next station. Each receiving station has a facility for plaguing your material requirements' and the individual recording

009883/0888

Stations are connected one after the other to an electrical system which actuates the pick-up valve of the station in question depending on the current demand from the locking device provided at this station or not confirmed. The mode of operation of such a: * Pick-up valve is in connection with Fig. explained.

In all previously known systems of this type, there was always ™

there is only one storage unit for the goods to be distributed, from which the individual receiving stations were fed. The use of only a single source of supply however, was a limitation for the industry.

The invention enables the use of two or more stores for the goods to be distributed, regardless of whether these stores are close together or quite far apart. In each case, supplied by the stores good can to a number of pre-selected, * nen receiving stations are distributed angeschlosse- to the distribution line. The stores are connected in such a way that they are all able to deliver their goods simultaneously to the predetermined receiving stations which have a need, with one receiving station at each point in time. is only fed from one store. According to the invention, the goods can be delivered not only as a function of the needs of each receiving station, but also to receiving stations that have a need for goods supplied by a specific store. This system shows a versatility that the textile industry has not been able to offer up to now.

Fig. 1 illustrates a schematic representation Embodiment of the invention, in which a distribution system all receiving stations of one or two Store or a predetermined number of receiving stations from the one and the remaining receiving stations able to load from the other memory. The system is particularly versatile and adaptable, than the store loading a given receiving station can be changed in such a way that a Multiple switches flipped or a single stopper or "a hand shut-off valve in which the Pasern flowed through Line inserted and another plug removed. In this embodiment of the invention, two are capable Fiber stores A and B in a moving air stream to deliver suspended fibers to multiple receiving stations 65O, 652 and 654. As from the description below the operation of the device according to FIG. 1 even more clearly this embodiment is not limited to a certain number of receiving stations, the manner in which several recording stations are switched on or off will be explained in more detail.

In this embodiment, a main control in the form of a number of relays is assigned to each memory, which the memory for the delivery of fibers in a conveyor line 676 and cause the conveying line to be blown through after all receiving stations at which a fiber demand existed, have been filled. The main controller 656 is assigned to memory B and the main controller 658 is assigned to memory A. Switching on the distribution system for both storage units is carried out by applying an electrical potential of, for example, 110 V alternating current on two lines 66O and 662 *

The receiving stations 65Ο, 652 and 654 are pick-up valves 666, 668 or 67Ο assigned, so that when one of these valves is open, fibrous material from the conveying line 676 removed and the air conveying the fibers is sucked into a conveying line 678 under the action of a fan 68Ο will. The fan 680 can be connected to voltage by applying an electrical potential to lines 68Oa and 68Ob laid or only switched on when the fibers are distributed or the system is blown through. Optional Each receiving station can have its own fan assigned to it. The mode of operation and the structure of the collector valves 666, 668 and 67Ο are explained in more detail in connection with Fig # 2.

The distribution system according to this embodiment of the invention is able to meet the fiber requirements of each of the receiving stations 650, 652 and 65 ¹ I- as often as a level switch 682 or 686 assigned to each of these receiving stations is open and thereby indicates a need for further fibers at this receiving station. The position of each of three multiple switches 69O, 692 and 694, each consisting of five individual switches, determines from which store the assigned receiving station is to be loaded. If, for example, one of the multiple switches is in the "upper" position, in which the multiple switch 69Ο is shown, the relevant receiving station is only fed through the store B. If, on the other hand, one of the multiple switches is in the lower ¹¹ position, in which the multiple switch 694 is shown, the receiving station assigned to it is only loaded through storage B. This choice between the upper and the lower position is of course only arbitrary and only serves This embodiment could of course have more than two memories

009883/0888

have by adding more positions that the multiple switches are able to assume, and additional circuits of the already existing type. When the multiple switches are in the positions shown in FIG. It can be seen that all three receiving stations from each of the two stores or two receiving stations from one and one receiving station from the other store A

can be fed from ". Each of these receiving stations can can of course be switched off from the system so that no Pasern are fed to it by the relevant ON-OFF switches in a manner to be described below be switched.

In the embodiment shown, the receiving stations located closest to a store do not necessarily have to be fed through this highest store. If two or more receiving stations also have a need for pasers from one of the stores, the receiving stations located "to the left" of this store receive the Fibers first. Neither of these states i is necessarily indicative of the actual practical arrangement, since the receiving stations can be located at any point so that, for example, the receiving station part 652 could be arranged as close to the store A as to the store B. It is therefore evident that the schematic representation of the arrangement of the receiving stations according to Pig. 1 is not a limitation.

009883-0888

The operation of the illustrated embodiment is explained below on the assumption that, for example, the multiple switches 690, 692 and 694 are all are in the position shown and the level switches 682, 684 and 686 are all open and one Show fiber requirements. As often as all level switches Receiving stations to be loaded by the store B are closed and therefore no need for fibers indicate one of these receiving stations, current flows through the coil 696 of a timing relay 698 and the coil 700 of a Relay 701 * which releases the fibers from memory B. Distribution system is decommissioned while at the same time the circuit is interrupted, which activates memory B for the delivery of fibers. If the Distribution system is then switched on with the multiple switches (switch positions according to FIG. 1) to the Receiving stations 65Ο and 652 from memory B and the To load receiving station 654 through store A, the circuit for coils 696 and 700 is closed. The current flow goes through lines 660 and 702, one Normally closed contact 704, a line 706, a contact 708 of the Multiple switch 690, lines 710 and 712, the closed level switch 682, lines 714 and 716, one Contact 718 of multiple switch 690, one line 720, a contact 722 of the multiple switch 692, lines and 814, the level switch 684, lines 838 and 840, a contact 726 of the multiple switch 692, a line 728, a Kpntakt 730 of the multiple switch 694, a line 732, a. Contact 734 of multiple switch 694, a line 736, coils 696 and 700 across the line 662 and back to the voltage source,

009883/0888

The flow of current through coil 700 is instantaneous opening of the normally closed contact 737 »whereby the current flow through the coil 738 of a conveyor relay 739 via the lines 660, 740 and 742, the normally closed contact 737 and one Line 744 is switched off. The normally open contact 746 drops out at the same moment and thus prevents the memory B at a supply of fibers to the conveyor line 676. When restarting, the closing of the normally open contact 746 after the start of the current flow through the auxiliary coil 738 However, delayed by a pull-in delay for a short period of time, in order for the system to fully cope with the inclusion of fibers delivered by the store B into the conveying line 676.

The normally closed contact 704 has a pick-up delay of a few seconds on, so that the blowing on is even closer can be done in a descriptive manner. The opening of the normally closed contact 7O4 a certain period of time after the start of the Current flow through the coil 696 interrupts the flow of current via the coils 696 and 700. By interrupting the When the current flows through the coil 700, the normally closed contact closes 737 * while interrupting the flow of current over the coil 696 of the normally closed contact 704 closes again, so that the coils 696 and 700 are energized again. The current flow through the coils 696 and 700 is thus periodically in time with the time periods during which the normally closed contact 704 briefly opens and the normally closed contact 737 briefly closes, interrupted. The normally closed contact 737 however never closes so long that ~ due to the Pull-in delay - the coil 738 the normally open contact can close.

However, if the current flows through the coils 696 and 700 by opening one or both level switches 682 and 684 is interrupted, the normally closed contact 737 drops constantly, whereby constant voltage to the Coil 738 of the conveyor relay 739 is placed so that the Normally open contact 746 after a corresponding pick-up delay and thus the supply source B begins to supply fibers.

Between the times at which a level scarf · m ter opens and the NO contact 746 closes, the buyer valve of the receiving station is opened, which is to be fed first. To explain the exemplary embodiment shown, it is assumed that the fill level switch 682 is opened first and the fill level switch 684 is opened immediately thereafter. Of course, if only one of the two fill level switches 682 or 684 is open, the receiving station assigned to the open fill level switch can be loaded alone.

Since the receiving stations 65O and 652 both from storage B from are loaded, the receiving station 650 receives the fibers from storage B first, as they are ^ ■ development in Fig. 1 is closest to the supply source. if With the level switch 682 open, current flows through a pull coil 750 for a later in connection with FIG Acceptor valve 666, which will be explained in more detail, is too open. Of the The circuit runs over the line 660, the line 702, the normally closed contact 704, the line 706, the contact 708 of the multiple switch 690, lines 710, 712, 752 and 754, a changeover contact 756, a line 758 and an ON-OFF switch 76O to one terminal the pull coil 750 and from the line 662 via lines 762 and 744 to the other connection of the pull coil 750.

009883/0888

The Abnehmerventll 666 remains open for the delivery of fibers to the receiving station 6p0 until the level switch 682 closes and thereby indicates that the receiving station has received a sufficient amount of fiber. By closing the Sehalters 682, the circuit for a relay coil 790 of a relay 792 via the lines 660 and 702, the normally closed contact 704, the line "06, the contact 708 of the multiple switch 690, the lines 710 and 712, the level switch 682, the coil 790 and the lines 762, 744 and 662 closed * dA * by a normally open contact 802 is closed and a Urasehaltkoiitakt "flipped 756 from the line 754 onto a line 8O4 result, the Stromfluö is interrupted again by the pull coil 750, so that the Abnehmervenfeil 6co immediately closes, By closing the normally open contact 802, the fill level switch 682 is bridged, so that the current flows through the pull coil 790 until all stations to be fed through the store B have received fiber material, even if the fill level holder 682 opens again and another fiber requirement should arise.

If the fiber requirement of the receiving station 652 continues to rise |

is covered and the level switch 682 and the working ■ contact 8O2 closes, .Wird the circuit is closed by a pull coil 806, whereby the pick-up valve 668 is opened in the same way as the Aimehmerveritil 666. This circuit running through the pull coil 806 begins on the line 660 and continues via the line 702, the normally closed contact 704, the line 7O6, the contact 708 of the multiple switch 690, the lines 710 and 712, the level switch 682 (or the line 752, the normally open contact 802 and a line 800), lines 714 and 716, the contact 718 of the multiple switch 690, the line

device 720, the contact 722 of the multiple switch 692, lines 812, 814 and 816, a changeover contact 8I8, one Line 820, an ON-OFF switch 822, the pull coil and lines 762 and 744 to line 662 continue. On. the same way as in connection with the Arbeitsswelse Receiving station 652 described, the pick-up valve 668 remains open as long as the level switch is open 684 'indicates a need for further fiber supply. At the When the level switch 684 is closed, the coil 824 of a relay 826 is switched between the lines 814 and 762, which in turn at the potential of the lines 662 and 66O respectively. The one by closing the level switch 684 caused current to flow through coil 824 causes a normally open contact 850 to close and puts the changeover contact 818 from the line 8I6 onto a line 854, whereby the current flow through the pull coil 806 is interrupted and the pickup valve 668 is closed.

Since the receiving station 652 is the last from memory B. is to be loaded, the system is now blown through. By closing the level switch 684 the circuit is completed via the coil 700 and thereby the normally closed contact 737 opened, whereby the circuit via the coil 7.58 of the conveyor relay 739 is interrupted so that the normally open contact 746 opens immediately and memory B is switched off. The current flow through the supply coil 700 runs from the line 660 over the line 702, the normally closed contact 704, the Line 706, the contact 708 of the multiple switch 6 * 90, lines 710, 712 and 752, normally open contact 862, lines 8ÖO, 714 and 7-16, contact 718 of the multiple switch 690, line 720, contact 722 of multiple switch 692, lines 812, 814 and 816, the normally open contact 830, lines 836, 838 and 840, the

Contact 726 of multiple switch 692, a line 728, contact 730 of multiple switch 694, a line 736, coil 700 and line 662. Since coil 696 is connected in parallel with coil 700, it is also connected to voltage. After the predetermined pull-in delay of the timing relay 698, the normally closed contact JOk opens and interrupts the flow of current through the coils 69O and 700. \

By closing the level switch of the last receiving station to be loaded through memory B, in the present case the level switch 684, a circuit is closed via the pick-up valves of the receiving stations loaded from memory B, so that blowing now takes place. When the level switch 684 closes, the pull coils 750 and 806 are switched between the lines 762 and 736, which in turn are at the potential of the lines 66O and 662. The circuit is from the line 762 through the pull coil 750 * the ON-OFF switch 76O, the Umsehaltkontakt 756, a line 804 and the changeover contact 856 to the line 736 and from the line 762 via the pull coil 806, the ON-OFF switch lter, λ 822, the line 820, the switchover contact 818 ₃ the line 8j4 and the switch 868 to the line 736.

The system is blown continuously between the opening times of the normally open contact 746 and the normally closed contact 704. All of the take-off valves assigned to the store B, in the present case the take-off valves 666 and 668, are open, but the store B no longer supplies any further fiber material. When the normally closed contact 7O4 is opened, the circuit is interrupted via the coils 790 and 824, whereby the normally open contacts 802 and 83Ο drop out and the switchover «

contact 756 from line 804 to line 754 and the changeover contact 818 from the line 8 ^ 4 to the line 816 can be turned over. When flipping the switches 756 and the circuits across the pull coils 750 and 806 are interrupted, so that the Abnehraerventile 666 and conclude.

Furthermore, by opening the switch 704 the circuits via the coils 696 and 7OO are interrupted and the normally closed contacts 757 and 704 are closed Closing the normally closed contact 704 puts the circuit over the coils 696 and 700 are restored, so that the normally closed contact 757 immediately and the normally closed contact 704 with a pull-in delay opens, while at the same time the circuit via the coils 790, 824 and the pull coils 750 and 806 is closed again. In this way, as described, the affair blows itself through as often as it can the normally closed contact 704 opens until the level switch opens or 684 opens and a need for further fiber supply indicates. In practice, the number of reception stations to be supplied is usually so large that already one of the level switches will be open again after blowing through it once.

Simultaneously with the loading of the receiving station 650 the receiving station 654 is also carried out independently of this supplies the memory A. In this case, of course, a plug or manual shut-off valve 835 must be inserted into the Conveying line between the receiving stations 652 and 654 must be switched on to ensure that each receiving station is only fed by one storage unit.

The distribution system assigned to storage tank A works in the same way as the distribution system assigned to storage tank B, with the delivery lines in the

- 15 009883/0888

Feed pauses are blown through periodically. Since in the present example only the receiving station 654 is loaded by the store A, a circuit for the coils 860 and 862 is closed by the level switch 686, which is connected via lines όόθ,? 4θ, 864 and 866, a break contact 868, a line 870, a contact 872 of the multiple switch 690, a line 874, a contact 876 of the multiple switch 690, a line 878, the contact 880 of the multiple switch 692, a line 882, a, contact 884 of the multiple switch 692, a line 886, <| the contact 890 of the "bin switch 694, lines 892 and 894, the level switch 686, lines 896 and 898, a contact 900 of the multiple switch 694, lines 902 and 904, the coils 86O and 862 and lines 906, 908, 762, 744 and 662 When the fill level switch 686 is closed, the current also flows via the coil of a relay 912 from the line 16S> , which is at the potential of the line, to the line 902, which is at the potential of the line 662, via lines 914, 896 and 898 and the contact 900 of the Multiple switch 694. As described in connection with the controller 656, the normally closed contact 868 opens periodically, whereby the system is repeatedly blown through until the fill level switch 686 "opens and indicates a further fiber requirement of the receiving station 654-.

When the level holder 686 opens, the current flows interrupted via the coils 862 and 860 and closes the normally closed contact 916, whereby a coil 918 over ejte Line 920 between those at the line potential 662 lying line 762 and at the potential of the Line 66Ο lying line 864 is switched, which causes a closing of the working contact 922, which energizes store A so that it feeds conveyor line 676 with fiber material. ■ "■ ■.

contacts 922 is delayed for a few seconds, however that the pick-up station is in full readiness for fiber pick-up.

When the level switch 686 is opened, a circuit is also closed via a pull coil 924 and thereby a pick-up valve 670 is opened, the circuit from the line 886 at the potential of the line 66O via contact 890 of multiple switch 694, the Lei-SI lines 892, 894 and 926, a changeover contact 928, a Line 934, an ON-OFF switch 932 and the pull coil 924 runs to the line 762 which is at the potential of the line 662. When the level switch 686 closes and thereby indicates that enough fiber material has been fed to the receiving station, a circuit is established Closed via coil 910 from line 894 to line 762 and the changeover contact 928 switches from the line 926 to a line 930.

Since the receiving station 654 is the only station fed by the store A, the system is blown through when the fiber requirements of the receiving station 654 are met. When the level switch 686 closes, a circuit is closed across the coils 860 and 862, so that a normally closed contact 916 opens and the fiber supply from the store A into the conveying line is interrupted line 934 ,. the changeover contact 928, the conduit 930 ", a contact 936 of the multi-switch 694 and a line 938 connected between the lying on the potential of the line 662 line 762 and lying on the potential of the line 660 line 902. FIG.. ■

This embodiment of the invention also has the further advantage that any of the receiving stations

- 17 009 883/0888

can be completely switched off from the distribution system. For example, the receiving station 650 can thereby be shut down that the level switch 682 short-circuited by a switch 9 ^ 0 and thus an open of the collector valve 666 is prevented. This circuit can also be used in any of the other embodiments described use.

In Fig. 2 shows a modified embodiment of the inventions Λ is shown dung, wherein the distribution system comprises two memory and a number of receiving stations that can be charged only by a memory, and a second number of receiving stations, which according to the position one or more multiple switches can be charged from both stores in a manner similar to that described in connection with FIG. 1. In the embodiment shown in Fig. 2, three receiving stations are provided, one of which is always loaded by the store A and the other always through the store B, while a third receiving station can be loaded both from the store A and from the store B, wherein the desired memory * multiple switch, inserting a plug or a hand through the multi Umfegen - control valve and removal of a plug or other opening of another manual valve can be selected.

In this embodiment there is also a special pick-up valve 1000 is provided, which is used according to the invention in each of the embodiments according to FIGS. 1 to 3 can be. This take-off valve 1000 takes the fibers from the moving air stream via a shaft 1002, which feeds the fibers to a processing machine. This doffing valve 1000 is opened so that the fibers through the conveying line 1004 carrying air flow for example

is diverted into a junction IOO6 assigned to a receiving station 1008 as often as that of the receiving station 1008 indicates a fiber requirement by opening a PU level switch 1010. When the fill level switch 1010 is opened, it can still be closed illustrative way voltage can be applied to a tension coil 1012, which actuates a valve 1014, so that compressed air flows into a working cylinder IOI6 and moves a piston ^ 1018, which actuates a control flap 1020 and thus a channel 1022 opens.

As a result of the valve flap 1020 being opened, the Air flow into branch IOO6 and a flap 1024 to the side, which shuts off the branch and prevents leakage when the valve flap 1020 the chamber 1022 blocked. The position of the flap 1024 when the control flap 1020 is open is shown in dashed lines. The air flow moves past the flap 1024 into a tree 1026 in which a rotating Doffer 1028 removes the fibers from the air stream and into the arms of a second circumferential doffer 1OjJO * gives. The consumers 1028 and IO3O can access the same Like a blower IO36 or in any other way are driven. The air stream freed from the fibers flows through a curved, fixed sieve 10 ^ 2 as well d, through channels 1022 and 10} 4 to the blower IO36, which is via lines 1058a and 1038b is fed. The circulating buyer 10 ^ 0 catches the falling fibers and brings them into the shaft 1002 leading to the processing machine. Assigned to the receiving stations 1044 and 1046 Discharge valves 1040 and 1042 work in the same way to separate the fibers from the air stream in the Conveying line 1004, as often as corresponding control flaps 1048 or 1050 are opened by pulling the pull coils 1052 or 1054 to be connected to voltage. - 19 -

The operation of this embodiment of the invention is largely similar to that of the embodiment according to FIG. 1, only with the difference that only the central receiving station can be fed from both stores. Of course, the middle receiving station is not absolutely necessary arranged between the other two stations too be. Rather, it could be anywhere else and could add any number of these switchable pick-up stations without difficulty will. In addition, this embodiment could pit any desired number of "changing stations" be provided.

As with the embodiment according to FIG. 1, the illustrated embodiment is started up by applying an electrical potential to lines 1060 and 1062. As described in connection with FIG. 1, a multiple switch IO63 is designed in such a way that in its "upper" position according to FIG. is "switch charged only by the memory a. in addition, two stop valves 1064 and IO66 provided, one of which can be switched into the feed line 1004, respectively, so that the feed is the ^rt ufnahmestation 1044 ensured only by a Speieher. the check valve 1066 is closed when the "exchange station", as assumed in the example below, is to be fed by memory B.

1066 * For the purpose of description it is assumed that all three level switches 1010, I070 and 1172 are open are. Of course, the distribution system can meet the fiber requirements of each receiving station or any number of To meet stations.

By opening the level switch 1010, a Circuit interrupted via a coil I080 of a relay 1082 and here a normally open contact 1084 is opened and

fe a changeover contact IO86 from a line 1092 to a Line I090 relocated. When opening the level switch 1010 is also the flow of current through a coil 1094 interrupted, so that a normally closed contact IO96 closes. In addition, the opening of the switch 1010 has an interruption of the current flow through the coil IO98 of a relay 1100 result, so that a normally closed contact 1102 can close. When the normally closed contact 1102 is closed, a circuit is then established Closed via coil 1104 of a conveyor relay II06, so that a normally open contact II08 closes and thereby initiates the supply of fiber material from the store B. However, the normally open contact IIO8 closes with a delay, so that the receiving station IOO6 is completely

) would take from fiber material is prepared if the latter is in the Funding line 1004 is funded.

By closing the normally closed contact IO96, which is at the same time occurs with the interruption of the current flow through the pull coil 1094, a circuit is created through the pull coil 1012 via lines IO6O, 1110, the closed idle con-, takt 1096, lines 1112 and 1114, the changeover contact · IO86, a line 1116, the auxiliary coil 1012 and lines 1118, 1120 and 1062 closed. The current flow through The accessory coil 1012 is used to open the control flap 1020 in the manner previously described. The control flap 1020 closes in order to prevent further fiber material from being picked up for the receiving station IOO8 when the filling

stand holder 1010 closes, thereby indicating that the Receiving station 1008 before a sufficient amount of fiber has been taken up.

When the level switch 1010 is closed, current can also flow through the coil 1080 via the lines 1060 and 1110, the normally closed contact 1096, the line 1112, the level switch 1010, a line 1121, the coil 1080 and lines 1118, 1120 and 1062 flow. The current flow over the Coil 1080 causes the normally open contact 1084 to close, which means that current continues to flow through the auxiliary coil 1080 until all of the receiving stations to be fed from the memory B have been loaded, even if the The level switch 1010 opens again and the changeover contact 1086 flips over. When moving the Umsehaltkontakte 1086 from the line 1090 to line 1092 becomes the circuit Interrupted via the pull coil 1012 and the control flap 1020 closed.

When the level switch 1010 is closed, a current « circle via a pull coil 1052, via the lines 1060

As the receiving station 1044 is the last station to be supplied by storage B, closing switch I070 initiates the blowing through of the delivery line 1004 in the same manner as described in connection with FIG. 1. When the switch is closed 1070 circuits are completed by the coils 1094 and 1098 via lines IO6O and 1110, the switch IO96, line 1112, level switch 1010 (or line 1114 and normally open contact 1084), line 1140, the contact 1142 of the multiple switch IO63, the lines 1144, 1146 and 1148, the normally open contact II58, lines II60 and 1162, a contact 1164 of the multiple switch IO63, Lines II66 and II68, the coils 1094 or IO98 and the Line 1062.

As described in connection with FIG. 1, the break contact is due to the current flow through the coil IO98 1102 opened and thereby the further flow of current through the pull coil 1104 is prevented, while at the same time also the normally open contact II08 opens, whereby the fiber inflow from the Storage B in the delivery line 1004 is interrupted. That however, the opening of the normally closed contact IO96 is delayed, whereby a circuit via the pull coil 1012 during this period of time between the line 1118 lying at the potential of the line 1062 and one at the potential of the Line I06O lying line 1168 via line 1116, the changeover contact IO86 and the line 1092 is established. In a similar way, the current flows through the pull coil 1052 from line III8 to line 1168 via line 1154, the changeover contact 1152, the line 1157 and a switch II70. The opening of the normally closed contact IO96 has an interruption of the current flow through the coils IO8O, 1156, 1012 and 1052 and the distribution system goes about this, referring to the in connection with Pig. 1 described Blow through periodically until one of the level switches 1010 or I070 opens the bodice. - 23 -

During the time during which the store B is loading the receiving stations 1008 and 1044, a pulling coil 1054 is activated via the line I060, a line II86, a "break contact 1182, a line 1220, a contact 1218 of the multiple switch IO65" by opening the level switch II72 , a line 1216, a contact 1214 of the multiple switch IO63, a line 1212, a line 1202, a changeover contact 1200, a line 1190, the pull coil 1054 and lines HIS, 1120 and 1062 to open the pick-up valve 142 energized. % level switch 1172 also interrupts the circuit via coils II76 and II78 and closes the normally closed contacts II80 and 1182. Closing the normally closed contact .1180 causes a current to flow through the coil 1184 via the lines 1060, II86 and 1188, the normally closed contact HBO, Coil 1184 as well as the lines III8, 1120 and IO62. Then, after a short delay, a normally open contact 1174 is closed in order to d initiate the flow of fibrous material from the store A from.

If the level switch 1172 closes, indicating that the receiving station 1046 is sufficient Amount of fiber received, a coil II96 is energized, where ™ a normally open contact II98 closes and the changeover contact 1200 transferred from line 1202 to line 1204 will. Since the receiving station 1046 is the last of the memory A from station to be loaded tfc, is closed by closing of the fill level switch II72 to blow through the system initiated the manner described in connection with FIG. Closing switch 11-72 creates a circuit closed over the coils II76 and II78 so that the normally closed contact 1180 opens immediately, what to an opening of the normally open contact 1-174 leads. The normally closed contact 1182 is opened after a period of time during which current the pull coil 1054. via lines 1062, 1120, ■ - 24 -,

An exemplary embodiment of the invention is explained below with reference to FIG. 3 consisting of FIGS. JA, J5B and JC. Several recording stations are fed from three independent stores. At the Embodiment six pick-up stations are shown, but it goes from the following explanation of the operation the distribution system shows how receiving stations are simply added or removed can be. In addition, the receiving stations, as described in connection with FIGS. 1 and 2, are arranged in such a way that that the stations located on the "left" side are always loaded first. This arrangement has of course no physical significance as the recording takes place can easily be rearranged, but is only intended to explain the invention as clearly as possible to serve.

This embodiment of the invention is so far as well particularly adaptable and versatile than the

each feeding a specified receiving station Memory by actuating three hand switches, insertion a plug or a hand shut-off valve and removal of another plug or opening of another hand shut-off valve can be changed. Besides, the Distribution system constructed in such a way that further accumulators can be added without changing the circuit only a corresponding wiring is arranged in the same way as the existing circuit.

The stores A, B and C deliver fiber material via a conveyor line I35OO to receiving stations 1302, 1504, 1306, I308, 1510 and I512. Which of the receiving stations is loaded by the respective store is determined by the respective position of the manual switches assigned to each receiving station. In the manual control switches assigned to the receiving station 1302, for example, a manual switch 1314 is switched to a position which corresponds to the memory from which the receiving station must be loaded with fiber material when it passes through the first one to be loaded, ie the one furthest "left" this store represents the station to be loaded, while the switch is in the OFF position if it is not the first receiving station to be loaded. A switch I3I6 is then set in accordance with the memory from which the receiving station 1302 is to be loaded. A switch I318 is put in its intermediate position if the station in question is not the last station in the row to be loaded with fibers, or in its "end" position if it is the receiving station to be loaded last from the store in question, ie so around the station furthest "to the right" νψι of this memory.

In the following the operation of this modified embodiment of the invention is explained in more detail, If the hand switches are in the position shown in FIG. 3, the receiving stations 1302, 1304 and I306 from Storage A and the receiving stations I3O8 and I310 from Storage B powered off while the receiving station 1312 is being loaded through storage C. Here would a plug or hand shut-off valve I32O between the Stations I308 and I310 and a plug or hand shut-off valve 1322 between the receiving stations I3IO and I312 be switched on. Corresponding to the aforementioned arrangement of the hand switch is a switch unit 1324 of the hand switch 1314 as well as a switch arm I326 of the switch 1316 shown in position A. The switch I3I8 stands on "between".

Since the receiving station 1304 is not the first from the store If it is the turn of the station to be fed, the switch arm 1328 of a switch I33O is manually in the OFF position posed. The switch arm 1332 of a switch 1334 is in position A and a switch 1340 in the "Between" position, since the receiving station 1304 is not the last to be loaded by the store A Station is. The receiving station I3O6 is loaded last from the stations to be loaded through store A, when she has a need for fiber, which is why the switch arm 1342 of a switch 1344 in the "OFF" position and the switch arm 1346 of a switch 1348 is brought into position A. The switch 1350 is set to "end". Since the receiving station I308 is the first from the store B is from the station to be loaded, the switch arm 1352 of a switch I356 becomes the same as the switch arm 1358 of a switch I36O in position B. A

Switch I362 is set to "Between" / Since the receiving station 1510 is the rightmost station to be supplied by the supply source B, a switch 1564 is switched to "End". The switch arm I37O of a switch 1372 is in the "OFF" position and the switch arm I38O of a switch I382 is set to B. Since the receiving station I3I2 in the present example is the only station to be fed by the store C, a switch 1304 is set to "End". The g switch arm I386 of a switch I388 is brought into position C in the same way as the switch arm 1390 of a switch 1392.

In the following, the mode of operation of this embodiment of the invention will now be described, assuming that the manual switches are in the positions shown. It is further assumed that all receiving stations have a fiber requirement. As soon as one of these stations has a demand for fiber, the corresponding store begins of course immediately with the supply, so that not all receiving stations need to have a demand for fiber before the supply begins. i

In the schematic representation of FIG. 3, it is assumed that a current source between terminals L ^ and Lg every main control is switched on. Ice, rightfully so all terminals L ^ and all K terminals L2 could each be parallel be switched so that the potential only needs to be applied to one pair of terminals.

As in the case of those explained in connection with FIGS Embodiments, a main controller 1400, 1402 and 1404, respectively, is assigned to each memory A, B and C. At the Opening a level switch 14O6 opens the circuit

The current flow through the coil i860 opens the normally closed contact 1868 and interrupts the current flow through the coil I870, which further opens the normally open contact 1882 and thus interrupts the supply of fiber material through the store C into the conveyor line I300. The switch I852 delays its opening for a few seconds. During this time, the valve I926 is kept open by a circuit which is driven by the pull coil I900 from the line 1950 at the potential of the terminal L .. via the switch I385, the line 1956, the terminal 6 of the terminal block I9I8, a line I98O, a working contact 1942, the line 1916, the Kleppe 7 of the terminal block 1918, the train; spool I900, the terminal 8 of the terminal block I9I8 and the line 1920 to terminal 2, the terminal block I9I8.
