Definitions
- the present invention relates to a sorting device for systems designed to sort objects, particularly covers and the like, in which the device, loaded with the object to be sorted, is moved over a pre-established path along which a succession of collecting containers are arranged to receive the carried object which, upon command, is dropped into one of them.
- Sorting systems of the above mentioned type are used in various fields and particularly in the field of bulky postal correspondence, to select and forward correspondence.
- sorting systems of this kind consist essentially of a guide in the form of a monorail along which sorting mobile units are moved, each of said units having its motorization and control system and being capable to carry the objects to be sorted to an area where containers or bags are arranged to receive the sorted objects.
- Each of said mobile units consists generally of a carriage constituted by a succession of vertical containing compartments each for housing a single object to be sorted.
- Each of these compartments is in the form of an upperly open pigeon hole for charging the objects and is closed lowerly by a base wall openable on command for discharging the objects into underlying containers.
- the objects to be sorted are coded at codification stations and then forwarded to a loading station where, following to a command from a programmed control unit, the objects are loaded each into a respective compartment.
- Each compartment having reached the sorting area, passes above all containers arranged along its path and, when it arrives above the one corresponding to the desired destination for the carried object, the control unit operates the opening of the bottom wall and the object falls into the container.
- the main object of this invention is to overcome the above mentioned drawbacks by providing a sorting device of the type referred at the beginning which allows to sort in an orderly manner covers and the like still maintaining their leading edge orientation.
- a further object of the present invention is to provide a device of the above mentioned type so as to be simple in construction, inexpensive to manufacture, and free from jamming.
- fig.4, 2 stands for a bracket, movable horizontally in a direction 10, to which a supporting flat member 1 is rigidly connected at its upper end in a reading-desk fashion i.e. inclined towards the direction of motion, so that its surface of maximum size has its normal vector inclined downwards and making an acute angle with the velocity vector, said angle being preferrably of 20° to 45°.
- the supporting member 1 has a lower portion 8 bent backwards, substantially at right angle, so as to form a support for the object to be sorted.
- bent portion 8 is curved concave upward.
- the flat parts are made of, or coated with, antistatic, low friction material in order to help the sliding of sorted objects.
- the object 9 to be sorted is slided on the ejector 3 and finds its support on the bent end 8 (see fig.3).
- the hinge and the connection between the flat member and the bracket 2 are embodied in such a way as not to hamper the fitting in of the objects during loading phase, as can be seen in fig.1.
- the ejector through actuating means 4,5, can be rotated, in a direction opposite to the motion, by an angle ⁇ , about the hinge 7 (see fig.2).
- said actuating means consist of a lag 4 arranged at least on one of the ejector side edges, close to its lower end and of an actuator 5 rigidly connected to the fixed frame of the plant and, therefore, in a-condition of relative motion with respect to the lag 4.
- the actuator 5 which can be, for istance, electromagnetically or hydropneumatically driven, actuates a stop element 6 which moves from a backward rest position A to a forward position A′ in which latter it opposes the lag 4 in such a way to rotate backwards the ejector 3 through an angle ⁇ about the hinge 7.
- the lag is sized and arranged in such a way that the angle ⁇ is so large as to make the sorting object to overcome the border of the support 8.
- the actuator can be monostable (i.e. the stop-element 6, by means of a return spring, comes back automatically in its backwards position) or bistable (i.e. the element 6 comes back upon a command).
- the coded object is inserted in the respective sorting device by sliding it on the ejector.
- the control unit When the device arrives above the container corresponding to the desired destination for the carried object, the control unit operates the actuator 5 which moves forwards the stop element 6 which, in turn, opposes the lag 4 hence rotating the ejector 3 backwards by an angle ⁇ , the object is driven out of the support edge 8, and the longitudinal component of force of gravity makes it to slide into container (fig.2) where it lands with a certain inclination and falls down so maintaining the desired orientation of the leading edge.
- the restoring of the ejector occurs automatically because of the normal component of the force of gravity as soon as the engagement between the lag and the stop element ceases either because the lag overcomes the stop element or because the stop element moves backwards, according to what is programmed for next incoming device.
- the sorting device according to the invention is very simple both in its structure and in its operation and, hence, reliable.
- the restoring occurs automatically due to gravity and therefore the return springs are eliminated along with any possibility of jamming.
- the support bent end 8 may be, if necessary, provided with a silencer in order to further lower the noisiness level).
- the slope of the flat member allows to transfer the object on further inclined surfaces in order to reach container or bag rows located at different levels.
- systems built up of devices according to this invention are actuated by external means only and do not require independent motorization and control means.
- the ejector 3 may be provided with curved extentions 11 at its sides in order to provide support for objects in the form of papers or floppy objects (see fig.4)
- bracket 2 a plurality of devices can be mounted on bracket 2 thus increasing the compactness of the system.
