Description

Circuit arrangement for small conveyor systems, in particular for electric mail and Cable post systems The invention relates to a circuit arrangement for small conveyor systems, especially for cable mail and electric mail systems, in which the conveyed goods with the help the trolley can be sent to any receiving point. The control the wagon takes place depending on a tax effect given by the sending office, which are stored in switching means outside the conveyor system and in accordance with the Movement of the trolley through the individual stations from the one assigned to each station Switching memory is transferred to the switching memory of the next station.

It has already become known for electric mail and cable mail systems to use circulating wagons in a track ring, which can be loaded and unloaded as required will. For such systems with a plurality of operating points are already Facilities become known through which an optional control of the transmission and Receiving facilities is made possible. As a control means are known in the Special switching means are provided on the individual carriages, depending on the arrangements their setting influence the sending and receiving points. The invention avoids special switching devices on the car. It solves the task of one completely automatic optional control of the transmitting and receiving devices of the individual Operational units using the concept of passing on the Target identification with the help of step switches, which the individual route sections are assigned and through their setting the target identifier is given.

According to the invention, the selective traffic is achieved in that the operating station is assigned switching devices for selecting the receiving station in this way are that when you operate these switching devices (button contacts) in a Shipment preparing operating point that identifies an unloaded carrier, The feature passed on in sections is suppressed and the one set in the transmitting station Destination is passed on to the next section of the route.

The additional loading of a carrier is achieved by that when you press the each operating point to choose from the receiving office assigned switching devices (button contacts) a circuit is established, become effective in the switching means that prevent the unloading of the conveyed material. 'In the drawing, an embodiment of the invention is shown.

The operating points with the order numbers 3 and 4 are shown in the circuit. There are as many voters provided in each route section as conveyors can drive in the section, in the example 3 voters are provided with the magnets S31, S ", Sag and S41, S42, S4 ,. It is now to the condition of the optional To meet traffic, the operating point selector of the route section immediately behind the transmitting operating point is forced not to check the operating point selector of the previous route section, but to check the destination set in the transmitting point and to take it over the operating point selector, e.g. S "" , is used to load onto already loaded carriers if the conveyed goods on the carrier are intended for the same receiving point. A specific step, namely o of the operating point selector, is provided for identifying an unloaded carrier , the branch number he corresponding step, e.g. B. Step 3 in the operating point 3, identifies the loaded car for the operating point in question.

Furthermore, buttons are assigned to each operating point, each with two working contacts own and serve to select the receiving point, z. B. owns that of the operating center 3 assigned button that selects operating point 4, the two working contacts t314 and t324 etc. In addition, three button contacts are assigned to each operating point tsl, t32, tsg and t41, t42, tos, which are closed every time a destination key the operating point is operated.

The following operations are now possible, which are based on the Circuit are described individually in the following.

a) An unloaded carrier arriving at an operating location should not be loaded.

b) An unloaded carrier arriving at an operating location should be loaded.

c) A loaded carrier arriving at an operating location should unload.

d) A loaded carrier arriving at an operating location should continue without unloading. e) One arriving at an operating point loaded carrier should be unloaded and reloaded at the same time.

f) A loaded carrier arriving at an operating location should be loaded additionally.

a) When an unloaded carrier is passing through the operating point selector, as will be explained under c), in position zero, accordingly is therefore when an unloaded carrier arrives in the Operating point 3 of the selector S21, not shown, assigned to operating point z with his arm S213 shown in the drawing in position zero. In a certain Distances in front of the operating point 3 are those actuated by the passing car Contacts f2a, f31 and f, 2. If the carrier activates the contact f2 " the output control switch solenoid A2 energizes: i. Earth, travel contact f2 ", magnet A2, Battery, earth.

The output control switch A2 switches its arm A21 to the first Step. The travel contacts f31 and f32 are then closed, but without any effect, since the operation selector arm S213 is at zero and no key has been pressed. Of the The conveyed goods carrier drives through station 3 and activates the Fahrlcöntakt f33. Of the Input control switch solenoid E3 is energized: e.g. Earth, travel contact f, 3, magnet Es, Battery, earth.

The input control switch E3 switches its arms E31 and Egg forward one step. Which step he is currently on is irrelevant in and of itself. It is therefore assumed that when f33 is actuated, it comes to step i. Now the travel contacts f3 and f35 are closed. A test circuit is prepared by contact f34, while contact f35 connects an interrupter U3 to the operating solenoid S, which is on any step: 3rd earth, interrupter U3, break contact p3E, travel contact f35, input control switch arm E32 step i, operating point selector magnet Ssl, battery, earth.

The magnet S31 switches its arms S, 311, S312 and S313 on until until the arms are at zero, then the following test circuit is established: 4. Earth, Battery, test relay F ", travel contact f34, input control switch arm E31 step i, selector arm S "1, selector arm S213, output control switch arm A21 Step i, normally closed contact n31, earth.

The test relay P responds and opens the circuit with contact p " for the magnet S ". Now the used voter has the operating point 3 the target o, that is, the indicator: "unloaded carrier" from the previous one Track section added. If the input control switch solenoid E3 is activated of contact f33 is set to step 2, for example, the test circuit 4 closed via the arm S321 of the operating point selector S32. When entering further The same processes take place, however, with the help of the control switch each time the next operating point selector to accept or pass on the Target number initiated. As soon as the considered carrier is the operating point 4 approaches and actuates the travel contact f38, the output control switch A3 is switched to moved one step further. It must now be done before the conveyor system is put into operation the condition must be met that the output control switch and the input control switch of a route section stand on the same step, then check when entering of the goods carrier in the following section and actuation of the travel contacts, z. B. f43 to f45 whose operating point selector, z. B. S41, the destination of the operating point selector of the previous section. The same processes are repeated for all of them following sections of the route and for each car.

b) In operation point S, operation point 4 the button contacts t314 and t324 are closed. As soon as an arriving unloaded Conveyor carrier actuates contacts f28 and f31, the following test circuit comes on conditions: @. Earth, normally closed contact iz ", output control switch arm A21 step i, arm S213 step o, button contact t31, relay R3 winding I, travel contact f31, battery, Earth.

Relay R3 connects: 6th earth, normally closed contact pgg, normally open contact r33, Relay R3 winding 1I, battery, earth. Relay N3 responds: 7. Earth, normally closed contact ", Normally open contact r32, button contact t33, delay relay N3, battery, earth.

Relay N3 binds: B. Earth, Rühekontaktp ", NO contact? Z33, Relay N3, battery, earth.

The starter relay B3, which switches on the elevator motor, responds: 9. Earth, elevator contact m31, normally open contact r34, relay B3, battery, earth.

The distance from contact f31 to the unloading point for the conveyed goods is so large that the elevator is in the driving position when the load carrier reached the operating site. The elevator separates as soon as it is in which he unloads or loads or does both at the same time by opening the Carriage position contact in "the circuit for relay B3. The elevator locks in this position with the help of a pawl, not shown. As soon as the unloaded When the goods carrier drives through the operation point, it takes the load off the elevator away. When the travel contact f34 is actuated, since relay N3 is energized, the Check via arm S213 of the previous company position selector prevented and directed via the buttons.

fo. E, rde, battery, relay P3, travel contact f34, input control switch arm E31 step i, operating point selector arm S311, key contact "4, normally open contact iz32, earth.

The operating point selector S31 in the section of the route at point 3 checks So on the pressed button, he has recorded the destination of the broadcast. When relay P3 responds during testing, relays R3 and N3 drop out. To opening of contact f34 also releases P3. The moving goods carrier is uncoupled the elevator, which automatically returns to its rest position.

c) The carrier is to unload in the operating station 4. As soon the contact f41 of the conveyed goods carrier is closed, relay R4 responds.

i i. Earth, battery, travel contact f41, relay R4 winding I, operating point selector arm S313 Step 4, output control switch A31 Step i, normally closed contact n41, earth.

The normally open contact r44 switches on the elevator motor Relay B4 energized. When contacts f44 and f45 close, the operating point step is activated via r41 4 connected to step o, the selector S41 is forced to zero in the following Check circuit: 12. Earth, normally closed contact z41, output control switch arm A31 Step i, operating point selector arm S313 step 4., normally open contact r41, core zero, Operating point selector arm S421 step o (if the input control switch E4 at Closing of f43 was set to step 2), input control switch arm E41 step 2, travel contact f44, relayP4, battery, earth.

As a result, the unloading carrier is marked as unloaded. The labeling is now from section to section until the next load transfer.

d) If a loaded carrier enters an operating site without unloading, drives through, then the destination of section is via the electoral field of the operating point passed to section. The processes are the same as described under a, only that the operating point selector is not on o, but on the destination number of the car. Sends z. B. position 3 after position 5, then in position 4 the following Test circuit come about: 13- earth, normally closed contact u4 ,, output control switch arm A31 step 2, operation selector arm S323 step 5, arm S431 step 5, input control switch arm E41 step 3, travel contact f44, relay P4, battery, earth.

e) If a program is being prepared in the operating point 3, then by the incoming goods carrier, whose conveyed goods for the operating point 3 is determined, relay N3 is also energized via normally open contact y32, since the button contact t33 is closed. Relay N3 switches the test circuit with contacts n31 and n32 for the relay P3 to the buttons, so that the operating point selector of the section position 3 takes over the target corresponding to the key pressed.

f) Additional loading.

The requirement that one and the same conveyed goods support the conveyed goods from several operating points that have set the same target, is tapped by the additional effort of a third arm of the operating point selector, z. B. S312, S322 S332 and a second arm of the output control switch, e.g. B. A32 allows. As soon as an operating point selector stands on the step, that of a depressed one Button corresponds, the relay Z is energized, z. B. for position 3 in the following circuit diagram: 14- Earth, battery, travel contact f32, relay Z3 winding I, button contact t324, arm S3,2, step i from control switch arm A32, 'Earth.

Relay Z3 binds and closes a circuit for relay Ra.

i5. Earth, normally closed contact ", normally open contact z3i, relay Z3 winding II and relay R3 winding III, battery, earth.

Via the passenger position contact ina2, which is closed when the elevator is in the take-along position, and via the working contact zag an unloading prevention magnet V3 is excited, for example, the gripper of the elevator so that it moves the goods on the carrier cannot tap (not shown).

In the case of systems with points, it is now preferred to branch off the line or sidings for which points are required is activated by energizing the relay R not an elevator switched on, but the turnout by a turnout magnet is provided, or z. B. prepared the switch setting for trailing switches.
