Definitions

  • the present invention relates to a machine for preparing discrete queues of stacked products, in particular food products, such as rolls, buns, etc.
  • each line of products includes six stacks of product and each stack includes two products on top of each other, but the invention is not limited to this provision.
  • a disadvantage of this installation is the manual positioning of the rolls, first at the exit of the first conveyor, then at the geometric shaping of the pile. Indeed, the rolls come out of the oven with a relatively high flow rate of the order of 20,000 per hour, and selecting a predetermined number of buns from a pile and shaping the pile can, by fatigue, cause random positioning of the products on the second conveyor, which is detrimental to the operation of the entire installation.
  • An object of the present invention is to provide a machine for preparing lines discrete stacked products which does not suffer from the above mentioned drawbacks.

  • the level of the arrival end of the outward conveyor is higher than the level of the end of the return conveyor, the difference in levels being the order of the thickness of the base of a tank.
  • a first intermediate fixed plate is placed between the arrival end of the outward conveyor and the departure end of the return conveyor, the first plate possibly oblique.
  • the evacuation conveyor consists of a band conveyor located in the extension of the direction from the end of the conveyor go to the departure end of the return conveyor, with a level lower than that of the departure end of the return conveyor, the conveyor belt being provided with projecting lugs, the conveyor outlet supplying the bagging machine.
  • each pusher of the linear transfer conveyor is consisting of a plate with two V-shaped notches while each lug of the discharge conveyor consists of two distant parallel fingers, the fingers of a lug being able, in movement, to pass in the V-notches of a pusher.
  • a second intermediate fixed plate is placed between the departure end of the return conveyor and the departure of the evacuation conveyor.
  • the second plate is notched to allow the passage of the finger of a lug.
  • FIG. 4 comprises the downstream end of a chute 1 for supplying products which in the example shown are rolls, a conveyor to go step by step transport 2 on which aligned trays are filled and translated, a return transport conveyor step by step 3 which brings the empty tanks back to their starting point, a linear transfer device 4 from a full container from the conveyor going 2 to the return conveyor 3 and unloading the container, as well transferred, contained products, an evacuation conveyor 5 transporting the products contained in a bagging machine (not shown) and a pivoting transfer member 6 transporting products from chute 1 to the bins located at the start of the outward conveyor 2.
  • Trough 1 transports, as shown by the arrows F1, the products from the outlet of the oven (not shown) at the installation proper.
  • Trough 1 is made up of six lanes in which the products are manually oriented lengthwise next to each other, without empty between them at least at the downstream end of the chute 1.

  • the hanger 20 To the hanger 20, thirty-six pneumatic suction cups 23 are hung, distributed in six rows of six suction cups symbolically represented by small crosses in FIG. 4.
  • Fig. 5 shows the six suction cups 23 in a row hanging from the stem 20. Under the stem 21, there are thirty-six suction cups distributed in the same way.
  • Each suction cup 23 is associated with a hose flexible, not shown, in which a vacuum is created when the suction cup must hold by suction a product or restores atmospheric pressure when the suction cup must release the product.
  • the pivoting member 6 pivots alternately, around axis 7, 180 ° in one direction and 180 ° in the other direction.
  • each suction cup 23 is, on the left when looking at the drawing, in the center of a box occupied by a product in a of the six corridors of the chute 1.
  • the operation of loading a gallows consists in making it take the low position, then make the vacuum in the associated suction cups and, finally, make him take the high position, before making a half-turn.
  • the operation of unloading a gallows consists of making it take the lower position again, then releasing the products that settle and, finally, to make him take the high position.
