Definitions

  • the present invention relates to a device for supplying a machine with rigid elements in the form of bar segments.
  • the present invention aims to allow the realization of a refueling device in which the various operations are automated, simplified and facilitated to a greater extent than was the case until now in order to better meet the requirements of the technique.
  • the device according to the invention is characterized in that it comprises a hopper, a mobile receptacle intended to receive packages containing the said elements in the form of bar segments, a detector reacting as a function of the height of a stack of said elements in the hopper, and control means controlled by the detector and capable of moving the movable receptacle automatically maintaining a hau - tor predetermined relative to that of the detector.
  • the device according to the invention also lends itself to uses in other very fields of manufacturing cigarettes or similar products.
  • the installation visible in fig. 1 comprises a hopper 1 in the form of a well of rectangular horizontal section which opens at the inlet of an elbow channel 2 by which filter elements 3 are led to the inlet of a machine.
  • This channel comprises, in a manner known per se, two endless bands guided by rollers between which the filter elements 3 are moved.
  • filter elements is a rigid piece of cylindrical shape about 8 cm in length and constituted by the end-to-end assembly of three cigarette filters.
  • these filter elements are sectioned in three, then distributed so as to arrive in the desired order at the location where they are incorporated into the cigarettes.
  • the bent channel 2 is shown fully closed in FIG. 2. This device known per se need not be described.
  • a horizontal initial segment 2a of the bent conduit 2 is located opposite the base of the hopper 1 and the filter elements which are stacked inside this hopper while being arranged parallel to each other, as is will see later, are entrained by a current of air created by means of a fan 5 and move in the direction ie the arrow 6 so as to enter the duct 2.
  • the arrangement of the hopper 1 and its accessory devices is designed to simplify the introduction of the filter elements into the hopper, while maintaining their alignment and without them being subjected to shocks.
  • These filter elements are manufactured in a particular installation and for the needs of the organization of production, they are then packed in cartons 36 in the shape of a parallelepiped whose width corresponds to the length of the filter elements.
  • the device shown in fig. 2 comprises a receptacle generally designated by 7, the main part of which is a plate 8 which is normally disposed in a slightly inclined downward position so that the cartons 36 open on their upper narrow side can be placed conveniently on the receptacle 7 while being retained by the flanges 8a provided for this purpose.
  • the packages are fixed to the plate 8 by a suction cup 37, as will be seen below.
  • the refueling device has arrangements which aim to bring the receptacle 7 to a height which corresponds to that reached by the accumulation of the filter elements already contained in the hopper, to reverse the packaging of so that it is placed upside down inside the hopper itself, and move it upwards gradually so that it empties, the filter elements being distributed over the entire surface of the hopper while remaining parallel to each other.
  • the device comprises means which observe the upper level of the pile of the filter elements in the hopper and fur-to - measure that evacuation down elements in the channel 2 to the base of the hopper and who, when needed, order the operation of the receptacle 7 so that it comes to be placed in the correct position and operates the overturning of the packaging, as indicated above.
  • the hopper 1 does not have a front side wall on its front side. Indeed, it is constituted by a piece of bent U-shaped sheet metal arranged vertically and forming the vertical bottom 9 and the two lateral sides 10 and 11 which are provided with two vertical slots 12 and 13 whose role will be explained below.
  • the hopper 1 On its front front side, the hopper 1 is partially closed by an extendable wall constituted by a screen 14 whose horizontal upper edge is linked to a frame 15 surrounding the entire profile of the hopper 1.
  • This screen is constituted in the example described by a sheet of flexible material which passes at the base of the hopper on a roller 16 and which is wound on a reel 17.
  • This reel can be equipped with a spring device which constantly tends to wind the screen and consequently to move the frame 15 down.
  • this same frame 15 is connected to drive means which control its movements.
  • the vertical upright 18 located behind the hopper and provided with a guide slide 19, constitutes a rail allowing the drive means of the frame 15 to move the latter from top to bottom or from bottom to top. The exact constitution of these drive means is not shown in the drawing.
  • drive means such as a cable forming a closed loop on it - even and hung on pulleys arranged at the top and bottom of the upright 18.
  • the frame 15 carries a detector 20 which consists of a photosensitive cell arranged opposite the slot 13 and a light source (not shown) placed on the other short side of the frame 15 and capable of emitting a horizontal light beam passing through the slots 12 and 13 so as to act on the photosensitive cell.
  • the latter can be a photoresistor, a photoelectric cell or any other type of element sensitive to electromagnetic radiation and capable of emitting an electronic signal under the effect of such radiation.
  • the signals emitted by the detector 20 are led to a control device, certain elements of which are shown in FIG. 1 and which ensures the programming of the automatic operation of the refueling device as will be seen below.
  • the frame 21 of the device described consists of a set of bars forming a rigid structure which keeps the hopper 1 in place as well as the upright 18.
  • This frame 21 also keeps in place two vertical guide uprights 22 and 23 as well as a rod drive thread 24 which is arranged parallel to and in the vicinity of the upright 22 and the lower end of which is linked to a return gear 25 so that this rod 24 can be driven in rotation from a shaft horizontal rotary 26 driven by a motor (not shown).
  • Two guide sleeves 27 mounted, one on the upright 22, and the other on the upright 23, are rigidly connected by a transverse bar 28 which passes behind the hopper 1, which constitutes a mobile assembly. On the bar 28 is fixed a nut 29 which, as seen in FIG.
  • Consoles 30 which extend on either side of the hopper 1 forwards, from the two ends of the bar 28, bear bearings 31 which guide a rotary shaft 32 controlled by a reducer motor 33.
  • the frame of this motor is also integral with the movable assembly (27, 28) which carries the receptacle 7.
  • the shaft 32 carries and controls the receptacle 7, the drive means of which are therefore entirely different from those of the detector 20 , a cell 43 similar to the cell 20 controls the movements of the moving assembly 27, 28.
  • one of the bearings 31 is seen mounted on a console 30.
  • the receptacle 7 is shown simultaneously in its lowered position and in its raised position.
  • the support plate 8 provided with flanges 8a is fixed to a support frame 34 formed by two parallel profiled bars connected by end plates.
  • This frame 34 is itself fixed by means of eyelets 35 to the shaft 32.
  • the packaging 36, placed on the plate 8, can be closed by a shutter 38.
  • This sliding shutter 38 is constituted by a plate plate allon - Gee carried by two slides 39 engaged one and the other of rigid cylindrical rods 40 secured to brackets 41 fixed to the frame 34.
  • the receptacle 7 can pass from the lowered position in which the plate 8 is arranged so that one can easily place on it a package 36 containing filter elements 3 arranged parallel to the thickness of the package, to an elevated position in which the package 36 is completely inverted and is inside the hopper 1.
  • the suction cup 37 holds the package 36 in place.
  • the frame 34 carries at its two ends means for guiding and controlling the sliding shutter 38.
  • a small cylinder is preferably provided (not shown) mounted on one of the stirrups 41 and capable of moving the shutter 38 from the open position in which it is shown in the lower left part of FIG. 2, in the closed position in which it is shown in the upper part of the same figure.
  • the device described can operate automatically while retaining great flexibility in its operating mode.
  • control means controlled by the detector 20 can be adjusted and adjusted so as to operate in different ways.
  • the frame drive means 15 are controlled so as to lower the latter slowly along the hopper.
  • the drive means are controlled so as to raise, for example in stages, the frame 15 along the hopper.
  • the receptacle 7 its operation will be controlled by the detector 43, but differently: Normally, the receptacle is maintained at an average height and in the position of FIG. 1, that is to say the position lowered so that it can be loaded with a package 36 at any convenient time.
  • a stop ⁇ 42 provided on the hopper 1 at a height corresponding to the minimum level that the stacking of the filter elements must reach, will cause the emission signal when the frame 15 reaches this stop.
  • the gear motor 33 will be started so as to rotate the receptacle from the lowered position to the raised position while bringing the shutter 38 to the closed position during this movement.
  • the packaging 36 will then be held by the suction cup 37 and the stacking of the filter elements contained in this packaging will be supported by the shutter 38.
  • the signal given by the arrival of the frame 15 at the height of the lower stop 42 will engage in addition to the tilting of the plate 8, the start-up of the means for driving the receptacle, that is to say the start-up of the motor driving the shaft 26.
  • the receptacle will therefore move downwards which will be stopped when the package 36 is presented with its lower edge immediately above the stack of the filter elements in the hopper.
  • the control means of the shutter 38 will be started so as to release the contents of the packaging 36 which will fall into the hopper without the stack losing its horizontal orientation and perpendicular to the pivot axis of the receptacle.
  • the light beam driving the detector 20 will then be closed, which will have the effect of raising the frame 15 step by step as we have seen previously.
  • the drive means of the receptacle will be coupled to the drive means of the frame 15 so that the movable element 27, 28 moves upwards preceding the movable element 15.
  • the movable receptacle 7 will be then controlled so as to be at all times at a predetermined height relative to the frame 15 and consequently to the detector 20.
