Definitions

  • dispatch vehicles such as driverless tramway cars, hanging; cages of wire tramways, carriers of pneumatic tube plants or of other such systems, are equipped with destinationmarkings by means of which they are able to prepare their route themselves.
  • dispatch containers for pneumatic tube conveyor systems have been provided with an element arranged to cooperate with either one or another of several so-called scanning means located adjacent the track and each serving to set a predetermined routing switch.
  • the marking element of the vehicle may initiate a mechanical operation in order to set the next following routing switch, but it is also possible'for this element to close a contact and thereby to afiect a control circuit for the switch-setting mechanism.
  • a dynamic control action may be provided by means of magnets fixed to the vehicle in order to affect the inductance of an element included in a magnetic circuit which acts on an electric circuit to bring about the desired control action.
  • the latter mode has great advantages over the former as there is no abrasion of cooperating parts.
  • the vehicle can happen to swing laterally, whereby its control element can change position and thus require special precautions to be adopted.
  • the scanning means serving to operate the control mechanism is affected magnetically.
  • the exciting elements preferably consist of permanent magnets but may instead be electromagnets energized by direct current.
  • the scanning means may comprise a choke wound on an iron core having two limbs an air gap between which is adapted to be bridged by the magnet on the vehicle. This choke is connected in an electric circuit and by varying the magnetic circuit of the core the inductance of the choke is afieeted in well-known manner to aifect in turn the electric circuit and initiate the respective control action.
  • the scanning means may be located in two rows extending lengthwise of the dispatch path and on opposite sides thereof. Each such. row has .a displaceable exciting element allocated to it on each of the containers.
  • the number of possible switching operations is in this case the mathematical product of the respective numbers of switching positions on either side of the dispatch container.
  • the non-displaceable additional magnetic element shall be unable to excite a scanning means of the control station intended only to be excited by a displaceable element on a container and in this way to initiate undesirable switching.
  • the/additional magnetic element, and the scanning means for cooperation with it may be arranged outside the paths of the elements provided for destination-marking. Such precaution may be undesirable for reasons of construction, but if adopted, and if the distance of these additional elements from the path of the other elements be somewhat small, then misrouting may occur especially where the plants concerned are somewhat large and the tolerances hence adequately greater than they are in the case of smaller plants.
  • Such misrouting will be initiated by a displaceable element of the dispatch container, which element causes the excitation of the scanning device arranged to actuate the respective control station without any other scanning means .becoming excited.
  • the routing switch will thus not be set although the destination-marking of the dispatch container agrees with the marking peculiar to the respective control station. Conversely, routing switches not to be controlled for the moment may happen to be affected. Misrouting is also possible where a plurality of elements for destination-marking are provided, or if the dispatch containers follow upon each other in such a close succession that the additional scanning means will be operated by an element of a container immediately behind another container that has not yet left the control station.
  • the invention provides that the direction of magnetization of the said new displaceable exciting element be at right angles to that of those elements which are displaceable to permit of destitration-marking.
  • the latter elements are selectively displaceable in a row of notches adapted to hold them in position.
  • These notches are distinguished from each other by reference characters such as numerals, whereby the vehicle shall be easy to adjust as to its destination. Also it will be easy to ascertain the destination of such a vehicle whilst it is being dispatched.
  • thevehicle may have a number of elements invariably fixed to it in a row. For each destination-marks ing a predetermined one of these elements is caused to be magnetized. In this way it will be possible for the des tination-marking to be provided with the aid of purely electric means.
  • FIG. 1 is a diagrammatic plan view of a dispatch vehicle as provided by the invention
  • Fig. 2 is a diagrammatic plan of a part of the dispatch path, this part being adapted to cooperate with this container
  • Fig. 3 is a diagrammatic plan of a part of the dispatch path, this part being adapted to cooperate with this container
  • FIG. 1 shows the circuit arrangement of a control station for a routing switch.
  • a dispatch vehicle A Fig. 1, is provided with permanent magnets V, I, II fitted to its longitudinal sides.
  • magnetization of magnet V is in the direction of travel with scanning meansV, I, II. associated with it in the path of the magnets V, I, II.
  • the scanning means V serves to affect an electric circuit by which the scanning means I, II are rendered effective.
  • the magnet. I excites. the scanning means I. whileby magnet II the scanning means 11 is excited.
  • the control mechanism of the next following routing switch is connected for operation by the scanning means I, II. This routing switch is hence set to determine the route of vehicle, A. If. the magnets I, II are in positions other than those here represented, then the scanning means I, II will not be. excited at the samemoment since the two magnets I, II will-not simultaneously face these scanning means. Consequently the control mechanism will not be actuated andthe respective routing switch will not be set.
  • the magnet V is used to restore the routing switch to normal when the control position is reached and this is still in its operative position but not intended to be set at this time.
  • the distances L1, L2, Figs. 1 and 2 indicate that the magnets V, I, Fig. 1, are spaced apart at the same e distance as are V, I, Fig. 2, and that this also applies for the magnets V, II, Fig. 1, as compared with V, II, Fig. 2.
  • the vehicle A has the magnet II inserted in the notch 40. Magnet I is seated in notch 6.
  • This vehicle may hence be saidto be vehicle 46, intended to be deflected or ejected-by control station 46.
  • the section of the dispatch track B which is shown, comprises a routing switch W for directing a vehicle into the path R.
  • the switch mechanism may be of any known construction depending upon the nature of the track. Wu and Wg are solenoids, electric motors or other motive devices for the switch, Wa being arranged to move the switch from the position G to the position R and Wg being arranged to restore it from position R to position G.
  • Contacts w2 and contacts wl are arranged to be opened and closed respectively when the switch is in posi tion G, whilst when the switch is moved to position R, contacts w2 are closed and contacts wl opened.
  • the scanning circuits V1, I, 11' each comprise iron cored inductive chokes, air-gaps of which are adapted to be bridged by the magnets carried by the vehicle and thereby affect control circuits and energize relays V, RI and RH respectively.
  • control circuits are well known and are described, for example, in U. S. Patents Nos. 2,609,433 and 2,518,865.
  • the relays V, RI, RII, RA and RG will, of course, be located at a convenient place adjacent the control station.
  • An arrangement for the destination control of vehicles comprising a fixed magnet carried by said vehicle and at least one other magnet selectively displaceable with respect to said fixed magnet along the length of the vehicle, the spacing between said magnets adapted to characterize a particular destination for said vehicle, a plurality of fixed scanning means located along the dispatch track of said vehicle, there being one scanning means per magnet, said scanning means being responsive to the fields of said magnets, switch means for said track and a control circuit responsive to said scanning means for controlling said switch means, characterized in that said magnets are so positioned that the direction of magnetization of said fixed magnet is at right-angles to that of said displaceable magnet, and that each of said scanning means are similarly positioned with respect to each other so as to respond to the excitation caused by its associated magnet exclusively.
  • control circuit comprises means responsive to the operation of the scanning means associated with said fixed magnet for restoring said switch means to normal in the event that it has been actuated by a preceding vehicle and the displaceable magnet on the vehicle next preceding is in a position not requiring actuation of said switch means.
