Station a material requirement is displayed. They are used to separate the substance from the air flow at the point of discharge, in which he is suspended. Of course, more than three pick-up valves or condensation devices or others can be used Types of material separators, such as the devices described in U.S. Patent 3,039,151 mentioned Kind be arranged at a corresponding number of receiving stations on which the conveyed cut in To be distributed depending on a demand signal generated by the station in question. The following is the The mode of operation of the electrical circuit controlling these pick-up valves is explained in more detail with reference to the figure.

By closing a main switch 16, a feed line 18 is connected to voltage, with a pneumatic timer 20 the functioning of the system will only be affected if the sequence of the distribution process is restarted, as explained in more detail below.

Each reception station of the distribution system is usually one open level control switch 26, 28 or 30 assigned, which is only closed when the relevant Station is supplied with the funded (jut.

It is assumed that all level control switches 26, 28 and 30 are open, i.e. all stations have a material

have required, and that the line 18 is connected to voltage when the switch 16 is closed. The assumed open state of the The level control switch 26 indicates that the first switched on line, furthest from the "Vorratsciuelle 32" distant station V .. has a material requirement. Since the line 18 is connected to voltage, the normally closed contact 22 is closed and the switch 26 is open, a circuit is established via a line 34 »a normally closed contact B ^ of a relay 62, a line 36, the consumer valve 10 and a return line 38 closed. At the same time, the line 34 connects via a normally closed contact D. of relay 62 energizes line 42, thereby energizing pull coil 44 of supply timer 46. This circuit is also connected to the return line 38. However, this coil 44 is a time delay coil, so that the Feed timer 46 does not close a switch 48 until after a certain time delay of typically five seconds. This time delay is impressed on the circuit to ensure that what is supplied by the supply source 32 Well actually ready for distribution,

When the switch 48 is closed, the coil 50 of a three-pole motor main switch 52 is energized and a motor 54 is connected Voltage applied, which initiates the conveyance of the goods to be distributed from the supply source 32 to the lines 56 and 58. The opened customer valve 10 is now able to deliver the conveyed goods to its assigned receiving station V *

give, the flow of material from the supply source 32 over lines 56 and 58 by one generated by a fan 60 Negative pressure is effected. The fan 60 can be electrically connected to the main line, so that the switches 22 opening and thereby turning off the system the fan also switches off at the same time; alternatively, as shown, the fan 60 can have a separate power source operated continuously and only switched off when the system is completely opened by opening the main control switch 16 is shut down.

When the first station is filled, the level control switch 26 closes and energizes the pull coil of the relay 62 via the line 64 so that the normally closed contacts Β., And D ^ open and the coil 44 is de-energized, the normally closed contact 48 is opened and the feed motor 54 is stopped. At the same time, the normally open contacts A .. and C. of the relay 62 close. By closing the contact A ^ current can be transferred from the line 34 via a line 66 and via the normally closed contact B ₂ of the relay 76 assigned to the second receiving station V _{2 to a line} 68 flow to which the pick-up valve 12 is connected so that it opens. At the same time, current flows from the line 34 via the line 40, the normally closed contact D ₂ of the relay 76 and a line 70 to line 42, whereby the spool 44 again energized, and a delay factor is introduced into the feed distribution. At the end of this delay

time span closes the normally open contact 48 and thereby closes on the previously in connection with the loading of the Receiving station V- described way the main motor switch 52 with the excitation of the motor 54 'so that the material is conveyed from the supply source 32 to the lines 56 and 72. at As a result of its promotion through the line 72, the property is the result of it of the open pick-up valve 12 is introduced into the assigned receiving station Vp via the latter.

If the receiving station V ₂ has no more material requirements, the level control switch sohließt 28 and thereby closes a circuit through lines 18 and 74 and the pull coil of the relay 76, whereupon the normally closed contacts Dp and Bp open this relay, which closing of the Discharge valve 12 and de-energizing coil 44 has the consequence, so that the main motor switch 52 is opened and the feed motor 54 is switched off. At the same time the working contacts Ap and Op of the relay 76 close. Sa it was assumed that the level control switch 30 is open and a material requirement is connected

excites and thereby the feed motor 54 is put into operation, which conveys the material via the lines 56 and 82 to the receiving station V * controlled by the pick-up valve 14.

From the above explanations it can be seen that the pick-up valves 10, 12 and 14 are actuated when the level control holders 26, 28 and 30 are closed and indicate a material requirement at the receiving stations assigned to them. In the system shown, the material requirements of the individual receiving stations are satisfied in such a way that the receiving station Y \. is charged, whereupon the remaining stations in sequence from the station furthest away in the distribution line to the station closest to the supply source 32 are filled. This sequence is determined so that the lines 58, 72, 82 and 56 can be practically free of any residual material during the operating time of the distribution system. By using this sequence, any material remaining in line 56 during the filling of the first station can be used to meet the material requirements of the second station, thereby reducing the amount of residual material remaining in the lines that is released from the lines during the blow-through process to be discussed must be blown out.

After completion of the loading of the last receiving station V, the level control switch 30 closes and energizes here the coil of the relay 84, whereby deescn normally closed contacts B ~ and D, open and the normally open contacts A, and 0, conclude. By closing relay contact A, the pull coils of all relays 62, 76 and 84 are switched on via the lines 34, 66 and 78 kept under voltage, even if at this point in time a fill level control switch indicating a material requirement is open at the assigned receiving station · Closing the normally open contact A continues to cause the lines 88, 90 and 92 are connected to voltage via the line 86, and there the relay contacts at this point in time CL, Cp and 0, are closed, those with the latter are over the lines 36, 68 and 80 connected consumer valves 10, 12 and 14 are opened.

The opening of all consumer valves 10, 12 and 14 at this point in time ensures that any residual material left in lines 56, 58, 72 and 82 during the dispensing process is removed by placing it in the closest receiving station is sucked in. In this way, the delivery lines are naturally automatic after the distribution process has ended freed from any residual material that was during of the distribution process may have accumulated in them. the The duration of this process is determined by the pneumatic Timer 20 determines whose tension coil 24 is excited via lines 86 and 94, whereby after a predetermined Period of time the normally closed contact 22 opens and thus interrupts the entire power supply to the system »

The opening of the pick-up valves 10, 12 and 14 during of the blow-through process, so that the residual material can be located receiving station can be promoted A safety feature as the fan is constantly sucking in air and creating a negative pressure in lines 56, 58, 82 and 96. If the negative pressure generated by this could act for a long time without relief, it would eventually close lead to a compression of the lines. The feed motor 54 is switched off after completion of the supply and distribution process and not again for loading the stations put into operation until the lines have been blown through and the entire working cycle is initiated again It is during this intermediate period that the lines could be compressed; however, the invention avoids this disadvantageous feature due to the opening of the pick-up valves 10, 12 and 14, so that this not only frees the lines from any residual material, but also compresses them the lines is prevented.

As mentioned, the fan 60 can be electrically connected to the main circuit be connected, so that at the same time the fan is switched off when the normally closed contact 22 of the Timer 20 opens and de-energizes the system. In the illustrated embodiment, the fan 60 is independent illustrated by the main circuit, but this should only

lion as better illustrating the invention and in no way restrictive.

The pneumatic timer 20 can be set to any predetermined period of time can be set. From a functional point of view, this period of time depends on the distribution required in the work cycle away. When the tension coil 24 is excited with a delay, the normally closed contact 22 is opened and then closed again, creating the distribution working cycle is initiated again from the beginning. The illustrated embodiment of the invention is of course not limited to the three receiving stations shown, since there are easily additional ones on each side of the distribution line Stations can be added without departing from the scope of the invention.

The number of receiving stations can be increased by any desired number of stations at each end of the distribution system or be reduced in size. More precisely, further receiving stations can be located at the right-hand end of the arrangement as shown in the figure can be added by simply removing line 86 and adding the desired number of tap valve-relay assemblies is inserted parallel to the existing ones. The line 86 would in this case via the appropriate Connections of the last inserted stations are placed

On the left side according to the figure could also additional stations can be provided by removing the line 94 and paralleling the existing stations any number of additional receiving stations is inserted, the line 94 again via the corresponding Connections of the leftmost station is switched.
