  PROCESS FOR THE PREPARATION AND AUTOMATIC DISTRIBUTION OF

  FRESH SANDWICHES, AS WELL AS IMPLEMENTATION MACHINE

  The present invention relates to a process for the preparation and automatic distribution of fresh sandwiches, as well as the automatic processing machine. We call fresh sandwich, the sandwich ready to be eaten, in the form of a crusty bread and fillings having kept their freshness, the bread preferably being a baguette-type dough bread

Parisian or equivalent.

  The invention aims to provide the consumer, and this automatically, such a sandwich, sandwich made at the time of the order from a crusty bread and toppings preserved in

optimal conditions.

  Sandwiches are generally prepared in advance in industry or in traditional distribution places: at service stations, self-service stores or sandwich bars. The prior preparation has major drawbacks: - baguette-style bread or equivalent to a duration of freshness and crispness limited in time; - the natural moisture in the filling is absorbed by the bread, which causes the bread to soften and become elastic; - the bread is sensitive to the humidity of the air, in particular in humid weather, which increases its softening; - to be kept in good hygienic conditions, the sandwiches are usually packaged in film, which retains moisture, and are stored in a refrigerated display case, which ends up destroying the organoleptic qualities of the bread; - industrial sandwiches are not made from real baguette or equivalent bread, but of a different composition, in which are added preservatives and emulsifiers which attenuate the phenomena mentioned but to the detriment of the taste qualities of a real crusty bread . In practice, the freshness of the sandwich is therefore currently only compatible with manual preparation on demand or very shortly in advance. However, this type of preparation also has drawbacks: in addition to the aspects of economic and organizational profitability

  and time management, hygienic conditions are also problematic.

  - especially when the preparer also gives change, or uses various means of cutting and displaying the garnishes kept in trays

open to the air.

  Furthermore, it is known from document US Pat. No. 4,202,260 an automatic sandwich-making apparatus. Such an apparatus realizes the assembly between a piece of upper bread, a filling and a piece of lower bread, without describing means making it possible to guarantee the

  freshness of the sandwich thus prepared.

  The invention proposes to remedy the disadvantages lO mentioned above, by carrying out a fully automatic preparation and distribution of fresh sandwiches using the combination of different manufacturing possibilities for various sandwiches, the sandwich being pilot

  between these posses by a lineire displacement.

  More precisely, the subject of the invention is a process for the preparation and automatic distribution of fresh sandwiches, consisting in storing baguette or equivalent dough breads in an area at a hot temperature of substantially between 40 and 60 C, at individually grasp each loaf falling by gravity from the storage area and convey the grabbed bread linearly in order to successively pierce it longitudinally in a blind hole, introduce into the hole thus formed a combination of fillings chosen from among several cold-temperature preserves substantially between -2 and +10 C, then condition the bread by bagging it and receiving it, the automatic preparation and

  distribution being centrally managed.

  According to particular embodiments, it is planned:

  - a lifting of the breads by conveyance out of storage for individual gravity recovery for gripping the breads at an ergonomic height; - an automatic cleaning cycle at the stage of inserting the linings; - optional heating of the sandwich with optimization of the management of cold and hot sandwich orders; - an impression of the bagging bag depending on the order made;

  - a sandwich lift before reception.

  Figures 1a and 1b illustrate an overall schematic view of an example of machine 1 according to the invention, with a facade 10

partially torn off.

  In these views appear, in fa, box 10, at least two access doors, 101, 102, a central command management unit 103 fixed on the internal face of the door 101, access to this unit for maintenance , repairs and installation of the connectors thus facilitated, a digital control panel 104 with ten entries, - four entries of ingredients, four entries of sauce and two entries hot / cold -, associated with an information table or a screen 105, and a payment entry 106 for validation. The management unit 103 includes a microprocessor and memories sized to the needs of the present

  application, in accordance with the skill of the art.

  S The user can thus order the filling of his sandwich chosen from among several possibilities, theoretically sixteen possibilities in the example illustrated: four choices of ingredients (chicken, ham, sausage, cheese) and four choices of sauces (mayonnaise, olive oil 'olive and lemon, tomato eVou madere), although some combinations are not viable (cheese - mayonnaise in the example) with, optionally, the possibility of obtaining a hot or cold sandwich. The digital keypad 104 and the information screen 105 can be replaced by a touch screen, which makes it possible to view the offers available at the time of the order and to order

by contact on this screen.

  l 5 The door 102 integrates a posse 107 for receiving the sandwiches, therefore locally remote from the control zone, composed of the elements 104 to 106. The reception posse 107 is sufficiently distant from the control zone to facilitate access thereto and favor the recovery of the sandwich (s) ordered in a reception orifice 69. A second screen (not shown) can be placed at posse 107, to dialogue with the consumer and indicate, for example, the last

  sandwich re, cu, a malfunction, or a delay.

  The machine 1 comprises a support frame 100 on which wind spreads different bread processing organs, these organs belonging to different possessions grouped together in treatment zones, inside the fa, block 10, baguette breads forming the basic component. fresh sandwiches to be prepared according to the exemplary embodiment, namely: a storage area 110, comprising an air-conditioned enclosure 19 coupled to an elevator conveyor 25, a guide area 111 in which a gripping piece 30 is fixed to an actuator fitted with carriages 31, 32 driven on perpendicular guide rails 33, 34 by drive motors 35, 36, a packing area 112, comprising a piercing position 108 and a filling position 109, and a packaging area 113, consisting of a heating posse 114, a bagging bag for sandwiches and printing of bagging bags 115 as well

  as the final reception posse 107 of the packaged sandwiches.

  The storage area is more precisely illustrated in FIG. 2. In this area, the air-conditioned enclosure 19, at a temperature of around 60 ° C. in the embodiment, thaws the baguette rolls 20 and keeps them warm and crisp. . Air conditioning is provided by electrical resistances, ventilation and hot air diffusers for

distribute heat evenly.

  The bread rolls arranged horizontally and transversely on superimposed and offset trays 21, fitted with conveyors 22. The wind conveyors driven by wheels 23 mounted on pigeons, where the drive being actuated by an electric motor 24, is triggered by

  ['management unit 103 according to user commands.

  By a cascade phenomenon, the loaves descend from tray to tray until transfer to the elevating bucket conveyor 25 which rises them. The breads are then recovered, individually, in a slide 26. The slide has a directional funnel 27 with progressive narrowing, of a shape adapted to vertically erect each loaf and initiate its fall by gravity without blocking. Each bread 20 is successively received vertically by the gripping piece 30 comprising a jaw 30a and a rod operated by an electrically controlled member connected to the management unit 103. The jaw 30a closes on the bread 20. The control of the part is adjusted by the management unit from a signal from an optical sensor (not shown)

  which detects the presence of bread and which is connected to the management unit.

  The path of the part in the guide zone 111 is more particularly illustrated by FIGS. 3a to 3c. Bread check 20 taken by the piece 30 is led from the storage area 110 to the filling area 112 by the base carriage 31, driven by a first gear motor 35 mounted on the horizontal rails 33, then to the packaging area 113, by the

  carriage 32 on which the part 30 is mounted.

  This mounting carriage 32 moves vertically on a rail 34 loaded by the base carriage 31, the drive being effected by a second gear motor 36 on the vertical rail 34. The linear guide zone of the part 30 is thus formed along two axes X and Z. in the same vertical plane. The motor reducers have adjustment codes. Trolleys, geared motors and rails forming a double horizontal and vertical actuator,

command by ['central unit.

  In the filling area 112 of the bread 20, the management unit 103 controls the motor 36 to stop the carriage 31 and the part 30 in line with the longitudinal piercing position 108 of the bread 20, as shown in particular in FIG. 4. The mounting carriage 32 is then driven by the motor S on the vertical rail embarks 34 from its basic position, to

  put the bread 20 into a cylindrical bar 37 with a central hole.

  A central blind hole 38 is formed from the upper end 2a of the

  bread 20, leaving the other end 2b with no holes.

  The cylindrical bar is made of teflon-coated stainless steel and has a sharp point with a diameter of 20 to 24 mm, equipped with a washer 39 in stainless steel, tapped, sliding and limited in its stroke by low and high stops. This washer makes it possible to accompany the bread to help with its undressing after piercing. The race is limited

by the motor encoder.

  lS The bar 37 is advantageously coupled to rotary drive means and electric resistance heating means (not shown). Helical ribs 40 have also been formed on the surface. These means make it possible to facilitate the distribution of the central bread crumb as the wall defining the hole is formed.

longitudinal 38 during drilling.

  At the end of the drilling stroke, the management unit 103 controls the geared motors to cause the mounting carriage 32 to descend to its basic position, and the displacement of the base carriage 31 to the right of one of the flexible packages 41b, according to the command

made by the user.

  The ingredients are contained in packaging

  flexible 41a to 41d, containing the fittings correspond to the orders.

  All the packaging is located in a refrigerated enclosure 42 at a temperature between 0 and +4 C in this example of embodiment, that is to say around +2 C. They are conditioned under vice and under

  modified atmosphere in an approved food processing workshop.

  The packaging includes a sealed 410 base.

  The seal 411 is removed after the packaging has been engaged and placed on a pump. The cover is extended by a tongue 412 out of the base to allow removal of the cover. When installing the packaging, the ingredients are never in contact with

  The operator, the ingredients descending directly by gravity into the pump.

  Once defective, the packaging is disposable.

  Each package is coupled to a vane pump 43a to 43d to push ingredients into a longitudinal cannula 44a to S 44d. The pump is open in its upper part to form a funnel or, by gravity, the ingredients are housed. To help force-feeding the pump, small paddles 430, fixed on arms 431 arranged in the same perpendicular plane, ensure the descent of the packing and a

  devoGtage. The arms 431 are actuated by drive means 432.

  As can be seen in FIGS. 6a and 6b, each cannula 44 has a double wall 440, 441, defining longitudinally a central channel 442, for transferring the ingredients, and three peripheral channels 443 to 445, limited by transverse partitions 446, to transfer a sauce among those compatible with the chosen ingredients. Such a cannula allows a gradual transfer of the chosen fillings in the bread, namely the basic ingredients and the sauce. Wind sauces fed via channels

lateral 448.

  The sauces are stored in disposable original packaging, of the "bag-in-box" type (botier à sac, in English terminology) and the wind is transferred into the cannula by peristaltic pumps or equivalent. These pumps operating in the two sees, suction or discharge, allow during the cleaning cycle, which will be described later,

to suck sauces.

  Each cannula 44 (FIG. 5a) is fitted with a spring-loaded valve 45, mounted on a sliding ring 46 along the cannula, and with a blower 47. Such equipment makes it possible, on the one hand, to keep the refrigerated area of the cannula and, on the other hand, to close the filling orifice 447 of the cane to avoid falls of filling or sauce. The ring 46 ensures at the same time a scraping action from the outside of the cannula and, by its weight, a

  role of bread maker on the cannula.

  The lining posse provides, for each filling package 41a to 41d, a hinged device with two flaps 48a and 48b, alternately driven against the packaging. This articulated device is actuated by a cam 49 controlled by the drive means 432 .. Such a device makes it possible to press alternately on the flexible packaging and thus promotes the descent by gravity of the lining, avoiding the doming phenomena. Voles 48a, located on the ingredient introduction side, is retractable to facilitate placement

conditioning.

  In operation, the vertical ascent of the bread 20 is immediately triggered, as for piercing, and the cannula 44b

  enter the central hole of the bread.

  Arrives at the end of the stroke in the bread, the filling pump 43b is activated to fill the bread with the ordered filling, then the carriage 32 drives the bread down as it is filled, at the speed provided by a variator of frequencies and allowing a regular filling of the bread. The filling can alternatively correspond to a predetermined dose of fillings, defined by the operating time of the

  peristaltic pumps programmed by the central management unit.

  At the end of the carriage 32 stroke, the filling action is stopped and the valve 45 ensures the closure of the end 447 of the cannula 44b

filling.

  The bread filled with its filling, making up a sandwich 200, lowered back to its basic position, is transferred to the

  conditioning 113 by actuation of the basic carriage 31.

  At the level of the conditioning zone 113, the basic carriage stops when it crosses the heating axis Ac or the ejection axis Ae 'depending on whether the command corresponds to that, respectively, of a sandwich

hot or cold.

  When the control sandwich is cold, it rises vertically by entrainment of the mounting carriage 32 on the on-board rail 34, along the ejection axis Ae. The heating device 50, which will be described later, is then released in order to free up the passage of the room. Arrived in the upper position, cited ejection position, the part 30 opens and releases the sandwich 200 which falls by gravity into the first bagging bag 51 of a bag store. The corresponding bagging and printing posse will be

described below.

  As illustrated in FIGS. 7a and 7b, when a hot sandwich is ordered by the user, the corresponding toasted bread is driven by entrainement of the mounting carriage on the vertical rail 34

  along the heating axis Ac to the heating position 114.

  At this posse, the part is engaged directly in a heating rod 50. Such a rod consists of resistances with teflon fins. The rod enters the central part of the sandwich where the filling is located as well as in the crumb. Optionally or alternatively, an external resistance coupled to a reflector (not shown) completes or performs the heating. Once engaged, the piece 30 releases the sandwich 200 which remains on the rod 50. This rod is fixed on a mobile support 52 which pivots on 180 in order to release the heating axis Ac and position itself on the axis d 'ejection Ae at the end of the heating cycle. Support is operated by means

52a.

  The pivoting time is established so that the sandwich uniformly reaches the target temperature, for example 50 to 60 in the example of embodiment. In the ejection position, a teflon stripper 53) is actuated by a plate 53a to push the sandwich, which falls by gravity into the packaging bag 51 and unhooks it. The developer also makes it possible to racier the rod. A lower ramp 54 makes it possible to maintain the

sandwich during its rotation.

  In order to optimize the delivery times of the sandwiches, a cold sandwich can be packaged in masked time between the start and the end of the heating cycle. To do this, the central unit controls the movement of the gripping piece 30 in order to grasp, pierce, garnish and eject a cold sandwich during the heating cycle of a hot sandwich previously ordered. As illustrated by FIGS. 8a and 8b, the order check label is printed, at the bagging and printing poses 115, on the bag

  51 which receives the sandwich correspond to this order.

  Such a posse comprises a bag store 55 and an ink system 56 coupled to a vice pump 57 to open the printed bag by suction. The ink system 56 consists of a carriage 58 mounted on a slide 59 and supporting a turret 60 equipped with 16 ink pads 61 which each print 16 viable combinations including the indications "hot"> and "cold". The turret is surmounted by the vice pump 57 fitted with two suction cups 62. An electric motor 63 ensures the

  movement of the carriage 58 by means of a connecting rod 64.

  Depending on the program provided by the central unit, the turret 60 rotates and positions the ink pad chosen for the reference to

  to print. The carriage 58 advances on the slide and the stamp prints the bag.

  Simultaneously the suction cups 62 come into contact with the bag 51 and, by the effect of the defect, suck up a first face 51a of the bag. When the carriage is recessed, the suction cups separate the vacuumed side of the bag, which allows the bag to be opened, thereby

  that the opposite face 51b of the bag remains gripped by the magazine 55.

  As illustrated in FIG. 9, the opening is maintained by an embosser made up of two movable arms 65, mounted on the spring 65a above the bagging zone. The arms 65 move apart (arrow F) during penetration into the bag of the sandwich which, ejected in free fall along the ejection axis Ae, simultaneously causes the bag to unhook. By moving away, the arms penetrate into the inlet of the bag 51, ensuring its correct opening for a guided transfer of the bagged sandwich up to

  final delivery pos 107, as shown in FIG. 10.

  The guiding is carried out, in the example illustrated, by a conveying elevator 66 which raises the sandwiches before their arrival at the orifice 69 at the final reception posse 107 at an ergonomic height by means of a gutter 67. A flight non-return 68, in the receiving orifice 69, ensures security closure so that users do not

  cannot access the machine parts through the receiving opening.

  The print on each bag 51 allows consumers to identify their

respective orders.

  The machine is equipped with an automatic cleaning block

  which allows for automatic and independent cleaning cycles.

  Such a cycle can be triggered when a filling packaging

is detected as vice.

  The cleaning block is then placed in place of the lining packaging and a waste water evacuation device is placed at the end of the corresponding cannula, then a new packaging is fitted in place of the vice packaging, the others posses of

  filling continues to operate during the cleaning operation.

  Information appears on the communication screen 105 in fa, box 10 indicating to consumers that the trim reference in

  cleaning phase is temporarily unavailable.

  The block has water inlet nozzles and bactericidal detergent. A program ensures the cycle of different phases of cleaning. Another block is fixed at the outlet of the cannula to evacuate the waste water. Before cleaning begins, the sauces are sucked in to free the pipes and to be able to clean them. The cannula feed pumps operate in the direction of the sauces' suction to redirect them to their packaging, before the pipes are cleaned or changed. A set of solenoid valves ensures the circulation either of the sauce or, subsequently, of the cleaning products. The program ensures

  automatically return the sauces to the pipes.

  Cleaning ermines, just uncouple the block

  cleaning and wastewater disposal device.

  The pumps advantageously have a permanent connection to the cleaning circuit which makes it possible to clean the internal organs of these pumps. A solenoid valve closes or

  the opening of this connection to the cleaning circuit.

  The invention is not limited to the embodiments described and shown. It is for example possible to simplify the guidance at the posse of final reception of the sandwiches by dispensing with the elevator of

  conveying by a direct connection through the gutter.

  On the other hand, it is possible to easily adapt the present machine in order to store, distribute and possibly reheat any type of sandwich, such as pizza, "panini", tart, quiche or equivalent, in

  eliminating the intermediate filling step.
