Abstract

ABSTRACT OF THE DISCLOSURE

The present disclosure describes a self-driven carriage for conveying and discharging items. The car-riage comprises a frame equipped with idle wheels and capable of moving along a path consisting of a monorail;
a device for discharging the items at either side of the path; and, onboard the carriage, first and second inde-pendent motors for respectively activating the discharge device and activating motion of the carriage.

Description

3~

The present invention provides for a self-driven carriage for conveying and discharging items to be sorted, wherein the items are placed, after codifying operations, on carriages or conveying planes that move along a fixed path, from which they are then automatically discharged when passing before the respective collecting zones.
There are known selecting and sorting apparatus wherein the items are laid on carriages or trans port planes connected to one another and forced to move along a fixed path by means of chains or other similar systems.
~ he discharge of the items, controlled by cams, rails or the like set all along the path, takes place either by tilting of the conveyor plane or by action lS f a pusher element that runs along the plane on which the item has been laid.
These systems, however, involve building complications and require, whenever changes to the path need to be made, too expensive interventions, and also the shut of the plant even over long periods of time.
There are also known carriages wherein the conveyor plane consist of a revolving belt actuated by a motor that moves along with the carriage, so that mechanical means set along the path need not be used, to effect the discharge~
More recently, there was a provision for a plant equipped with self-driven carriages. A plant wherein some at least of the carriages are provided with inde-pendent motors, which allows to spare the dragging devices and to obtain a considerable simplification in the entire structure, which is very flexible as well.
The carriage of the present invention is meant to be used in connection with the plants such as the ones just mentioned.

~2~8~

~ t stands out ~rom the previous ones due to a simpler building (particularly as concerns the means for making the carriage move forward) and more practically (consisting essentially in the upkeep operations and repair interventions being simpler).
Furthermore, unlike other known carriages, requiring guide-rails and separate rails on which act the driving wheels, the carriaye acc:ording to the invention has only one simple mono~rail for both func-tions.
According to the present invention, there is provided a sel~-driven carriage Eor conveying and discharging items to be sorted, comprising:
a frame equipped with i.dle wheels and capable of moving along a path consisting of a monorail:
means Eor discharging said items at either side of the path; and first and second independent motors onboard the carriage, for respectively activating said discharge means and activating motion of said carriage, wherein said second motor controls forward motion of said carriage and comprises a motor-transmission gear unit hinged onto said frame and capable of actuating a pair of driving wheels that act on said monorail from opposite sides thereof, and wherein resilient means are provided to act on said motor-transmission gear unit in order to keep the driving wheels in constant close contact with said monorail.
Thus, the carriage according to the invention is provided with independent motor means for controlling the motion thereof, and with further motor means, independent from the first ones, for controlling the discharge of the conveyed items; the carriage is meant to move along a path consisting of a monorail, and is equipped j~ .

- 3a -with hinged coupling means for the connection with analogous carriages.
The present invention will be now described in detail, with special reference to the enclosed figures, i.n which:
- Figure 1 shows a section of a carriage ac-cording to the invention;
- Figure 2 shows a ~;ection of the carriage ac-cording to the line I-I of fi.gure l;
- Figure 3 shows the partially sec-tioned view according to the arrow A of a carriage according to the invention;
- Figure 4 is the par-tially sectioned view o~
a carriage according to the invention, seen from above.
The carriage (see figure 1) consis-ts essentially of a support .. .~

;' /
/

', ,, ¦structure 1, that runs along a Monorail 2, of a motor unit 13 and of a conveying and discharging unit indicated as a ¦whole by No. 4.
¦The support structure 1 comprises a frame 5 leaning on the upper edge 6 o~ the monorail by means of a pair of idle wheels (front and rear) 7, and being provided with R pair of uprights 8, set at both sides of the monorail, on which there are mounted opposite idle wheels with vertical axis 9, that run on the walls of the monorail itself to avoid ¦side shiftings of the carriage.
¦In the lower part of uprights 8 there are idle wheels 10 ¦with horizontal axis, that run in contact with the under-¦side of a pair of flanges 11 of the monorail.
¦The carriage that moves in the direction of arrow V can ¦therefore run along the monorail by means of wheels 7; the ¦idle wheels 9 keep the front part of the carriage exactly ¦positioned on the monorail, while the positioning of the ¦rear part is carried out by the driving wheels, as will be ¦ hereinafter described.
¦ To frame 5 there is fixed a substantially vertical shaft 12 at which is hinged the support 13 of an electric motor 14.
To the shaft of motor 14 is keyed a pinion 15, which engages a crown 16 secured to a toothed wheel 17 which, in l its turn, gives a rotary motion to an analogous wheel 18.
¦ Wheels 17 and 18 are keyed on vertical shafts 19 that are ¦ mounted on support 13 by means of bearings; at the lower end of said shafts there are secured a pair of driving wheels 20 engaging, from opposite sides, the monorail 2.
Motor 14 makes the driving wheels 20 rotate, through crown 16 and the toothed wheels 17, 18. Wheels 20, moreover, keep 1 ~2~

¦ the front part of the carriage properly positioned on the ¦monorail itself.
¦ With a view to allowing, when necessary, the coupling Or a ¦number of carriages (one thereof drawing the others), frame l 5 comprises as well a pair of hinges 21, to which are ¦secured dragging bars, besides one or more absorbers, not ¦shown in the drawings.
¦There is also present a spring 25 or the like, linking ¦motor 14 to frame 5, exerting a tractive force tending to Irotate the motor unit anti-clockwise, as shown by arrow C
¦in Fig. ~. This is for keeping the adhesion between the ¦drivi~g wheels and the mono-rail constant. In particular, ¦when the carriage has to run along very curved stretches, ¦the spring 25 holds the motor unit (as well as the driving wheels) in such a position that the wheels 20 are compress-ed against rail 2.
In the upper part there are the means for conveying and discharging the items to be sorted, that may consist either f tiltable plates (that can be actuated mechanically or, ¦preferably, each by an electric motor mounted on the rele-¦ vant carriage) or, as illustrated in the drawing, of a ¦ rotating belt 24 mounted on a pair of rollers 22 parallel ¦ to the direction of feed of the carriage and mounted in their turn on the frame of said carriage.
¦ The rollers 22 of the rotating belt are actuated by a motor 23 preferably of the permanent magnet direct current type, l as its acceleration characteristics allow the same to be ¦ controlled very quickly: among other things, it is possible to adapt its speed almost instantaneously to the sizes of the discharge stations, and to make said speed fit at any .

. . .

~ 33~393 time to the plant requirements.
Either motor 23, 14 are fed, by sliding contacts 26, from feed rods set along the path and not shown in the drawings.
During working, the carriage is forced by motor 14 to move along the monorail 2.
The items to be sorted, after codifying, are placed each upon a carriage. As the car-riages pass before the collect-ing areas, a central control unit of known kind sends tension to the feed rods to which motor ~3 is linked; then belt 24 will be set in motion and, while rotating, will discharge the item at one side or the other of the path.
The particular shaping and arrangement of the parts permits to obtain several advantages in respect of the known appara-tus.
First of all, the structure of the monorail is very simple and unexpensive, and the carriages can be mounted thereupon in a very quick and easy way.
Due to the fact that each carriage is provided with an independent motor, it is possible to vary at will the capacity of the whole apparatus, by increasing or decreas-ing the amount of carriages, according to the requirements.
The carriage, thus devised, can even move along twisted and/or sloping paths, and the apparatus can be fitted without problems to the existing rooms.
In plants such as the one herein described, the tension of the employed current should be very low, for safety rea-sons; this, however, does not permit to fully exploit the characteristics of the permanent magnet motors.
For this motive, to the end of better exploiting the acceleration characteristics of such motors without detri-~1 ~ 31~3 ment to the operators' safety, in the carriages according to the invention motors 23 are fed with impulses the voltage of which is higher than the nominal one, but has a duration of few milliseconds.
In fact these motors have, at the starting, a considerable pick-up, of very short duration. It is then possible to use motors intended for 48 volt. working and to feed them, whenever belts 24 should be rotated to make them discarge the conveyed items, with vo:Ltage impulses of around 60~70 volts, of few milliseconds' duration.
In this case, the characteristics of the motor are exploit-ed at the most while the operations are carried out in safety conditions, without the need to resort to more powerful (and therefore heavier and more costly) motors.
Thus the discharge operations take a shorther time, and it is therefore possible either to increase the forward speed of the carriages or to employ, for the discharge, contain-ers with a mouth of lesser size.
Of course the sizes, as well the employed materials, can vary as a function of the requirements of use.
