  • the present invention relates to an automatic container filling machine, in particular with food products, preferably globular or short oblong, such as, for example, tomatoes, peas, pears, cherries, blackcurrants or strawberries.
  • Filling machines are already known comprising a vibrating feed hopper bringing the products to be packaged in containers passing over a conveyor arranged below said hopper.
  • known fillers in particular that described in document FR-A-2 011 265, comprise a lower belt located under the first conveyor and which drives the products thus recovered towards an elevating mechanism which brings back or recycles said products to containers being filled.
  • the means collecting the fraction of the product in particles which overflowed during the filling of the containers comprise a conveyor belt 86 receiving this fraction of the product and bringing it towards a belt 94 which makes it fall the fraction of particles in a rotary elevator 110 which brings this fraction back into the empty containers located upstream of the hopper 50.
  • the material having overflowed from the containers is collected on a tray supply and transported upstream, to a compartment for filling to be executed with the material having overflowed, said material falling in a rotating cylindrical envelope and collected in pockets formed by flanges.
  • An object of the present invention is to provide an automatic filling machine ensuring perfect recovery and without loss of time of overflowed products. containers to fill.
  • Another object of the invention is to provide a filling machine which makes it possible, moreover, to effectively control the filling of said containers.
  • the automatic container filler of the invention is of the type comprising a vibrating feed hopper, disposed above a first conveyor of a first series of containers, for bringing said products into said containers and it is characterized in that in order to collect the products that may fall outside of said.
  • first containers it comprises a second conveyor from a second series of receptacles arranged at a lower level of the filler with respect to said first conveyor and a guide chute disposed between said first and second conveyors, and conveying said products to said second receptacles.
  • the first and second aforementioned conveyors are connected together and form a single, endless conveyor, bringing the containers from their point of entry into the machine and from the aforementioned lower level, where they undergo a pre-filling, by the products conveyed by the aforementioned chute, at a higher level, under the feed hopper, for additional filling and towards their point of exit from the machine.
  • the filler also comprises a container filling control system comprising at least one weighing device comprising a weighing member connected to the movable element of the carriers which ensures the movement of the containers , said member reacting to predetermined weights, respectively maximum and minimum, of the containers being filled said device further comprising two switches, actuated selectively by said member during its reaction, to the first of which is controlled a stop command of the carriers and / or acceleration of the vibratory movement of the hopper and to the second of which is controlled a command to slow down said movement of the hopper.
  • a container filling control system comprising at least one weighing device comprising a weighing member connected to the movable element of the carriers which ensures the movement of the containers , said member reacting to predetermined weights, respectively maximum and minimum, of the containers being filled said device further comprising two switches, actuated selectively by said member during its reaction, to the first of which is controlled a stop command of the carriers and / or acceleration of the vibratory movement of the hopper and to the second of which
  • the part of the upper level of the conveyor extending under said feed hopper and up to the point of exit of the containers from the machine and that located at the aforementioned lower level and bringing said containers from their point of entry into the machine are arranged one above the other in the same vertical plane.
  • the machine of the invention eliminates any unnecessary recycling of the product in the filler since the overflow from the upper part of the conveyor is entirely recovered in the containers circulating at the lower level of this conveyor.
  • the device for controlling the filling of the containers of the invention makes it possible to increase the precision of this filling, which is thus done in a fully automatic manner without human intervention.
  • This device also makes it possible to avoid excess or lack of product in the containers to be filled.
  • the filler of the invention firstly comprises a vibrating feed hopper 1, preferably adjustable in height and driven by a motor assembly 2 advantageously provided with 'a variable speed drive.
  • the filler according to the invention further comprises one or more conveyors located at two different levels of the machine, at an upper level A below the level of the hopper 1 and at a level B lower than at level A.
  • the conveyor (s) are of the type constituted by a mobile element 4, carrying and ensuring the movement of the containers 5, this mobile element possibly being a cable or a belt moving in a sliding path 6.
  • the conveyor further comprises guides 7 , normally fixed, constituted by horizontal bars 8, integral with supports 9 which can possibly be connected to the sliding path 6.
  • a guide chute 10 Between the two levels A and B of the conveyors is disposed a guide chute 10.
  • the spacing of the lower edges of this chute can advantageously be selectively adjustable as a function of the size of the products passing through the filler. This adjustment will be made by a mechanism known per se.
  • the conveyor used is of the endless type.
  • the two conveyor levels A and B are connected together by means of a ramp 11, of a type known per se and comprising a set of pulleys P l , P Z , P 3 guiding the belt or the cable 4 which, of course, is endless and which is brought back from the upper level A to the lower level B of the conveyor by a driving pulley P driven by a motor element 30.
  • the guides 7 will extend only over the part of the conveyor conveying said containers, that is to say between the point of entry C of the containers into the machine and their point of exit D.
  • the part of the upper level A of the conveyor which extends under the feed hopper 1 and up to the exit point D of the containers and that located at the lower level B and bringing the containers from their point of entry C into the machine, are arranged one above the other in the same vertical plane.
  • the guides, and more precisely the supports are fixed on an oscillating support 12 mounted on a drive axis 13, extending under the sliding path 4.
  • This axis is carried by bearings 14, integral with the frame of the filler.
  • the drive of the shaft 13, and therefore of the support 12, the supports 9 and the corresponding guide parts is carried out by means of a set of connecting rods.
  • This set of connecting rods comprises a first connecting rod 15 rigidly connected to the axis 13.
  • the connecting rod set is completed by a second connecting rod 16 articulated to the connecting rod 15.
  • This connecting rod 16 is connected to an eccentric 17.
  • This eccentric 17 is driven in rotation by a driving element 18.
  • the eccentric 17 communicates to the connecting rod 16 a rectilinear sinusoidal movement which is transformed into a rotary movement of the axis 13 by means of the connecting rod 15.
  • the horizontal bars 8 of the movable part E of the guides 7 will be connected to the other horizontal bars of the fixed part of the rest of the carriers by any known means, in particular by means of flexible connectors.
  • the oscillating part E of the conveyor can also be mounted according to a second embodiment, the principle of which is moreover similar to that of the embodiment which has just been described.
  • the supports 9 can be connected to the support 12 by means of plates 19. These plates have a notch 20 making it possible to slide them relative to the support 12 and thus to orient the guides 7 in an oblique plane with respect to the vertical plane of the filler.
  • the plates 1 9 will be blocked relative to the support 12 by any known means.
  • the aforementioned oblique plane is materialized by the inclined axis of FIG. 2.
  • the container pressing device of the invention comprises a weighing member 21 connected to the mobile element 4 of the conveyor.
  • this weighing member is constituted by a lever articulated to an axis 22.
  • This lever is placed under the movable element of the conveyor, for example a belt and it is held, by means of a means return 23, such as a spring, in contact with the element 4 and movable between a high position and a low position.
  • the spring 23 may be calibrated so that the lever reacts to predetermined, respectively maximum and minimum weights of the containers being filled passing over it with the movable element 4. For example if the containers 5 are insufficiently loaded, and have a weight less than the minimum acceptable weight, the lever 21 will move to a high position. On the contrary, if the containers 5 are overloaded and have a weight greater than the maximum acceptable weight, the lever will move to a low position.
  • the weighing device comprises for each weighing member, two switches 24 and 25.
  • the switch 24 is controlled by a command 26 acting on the motor element 30 for stopping the conveyor and / or on the motor element 2 for the acceleration of the vibratory movements of the hopper.
  • the second switch 25 is controlled by another control 27 which also acts on the motor element 2 to slow down said movement of the hopper.
  • the lever 21 will be provided with any contact element 28 so that in its high position, the lever 21 actuates the switch 24 and in its low position the switch 25.
  • Figure 4 shows the case where the control system includes two weighing devices located respectively at the upper and lower levels of the carrier.
  • control systems 26 and 27 any suitable type of control, in particular electromechanical or electronic control systems.
  • the containers 1 to be filled are brought, by known means, to the point of entry C into the machine. They are juxtaposed joined on the conveyor which, as a result of the starting of the driving element 30 makes them pass from the lower level B to the upper level A.
  • the containers then circulate under the feed hopper 1 and they are then filled , preferably at reflux of the product to be packaged.
  • the containers of the upper level A which have just passed under the hopper 1 then pass into the oscillating part E of the conveyor, that is to say that where the guides are mounted on the oscillating support 12.
  • the containers then undergo transverse oscillations which allow either a compaction or an evacuation of the product overflow.
  • the containers are then brought to the exit point D where they are removed from the machine by any known means.
  • the weighing devices of the container filling control system can operate at any time separately or jointly.
  • the detection of a weight lower than the minimum permitted weight either at the upper level for boxes being final filled or at the lower level for boxes whose pre-filling level is insufficient may cause the boxes not sufficiently filled with product and / or product feed acceleration.
  • the detection of a weight greater than the maximum permissible weight for the cans being final filled at the upper level and for the cans already partially overfilled at the lower level causes the supply of product to slow down.
  • the conveyor could be provided, at an appropriate location, in particular after the hopper, with a compacting piston, ensuring a movement of the containers from bottom to top and vice versa in a plane substantially vertical, with a view, of course, to improving the compaction of the product in the containers.
