Definitions

  • the present invention relates generally to installations for cooking products such as bricks, tiles and the like.
  • the products to be cooked are placed on supports positioned on wagons.
  • the wagons loaded with raw products pass through a tunnel oven at a determined speed so that the products are properly cooked when the wagons come out of the oven.
  • this body of water is not provided above the factory floor level, which would make it possible to keep the rails on a single horizontal plane, but in a pit.
  • Lift tables are very expensive to manufacture when it comes to moving loads as large as the 80 tonnes of a wagon whose surface can reach 40 m2.
  • the present invention aims to propose a new simple device capable of ensuring the passage of a wagon between two upper and lower levels while keeping it always perfectly horizontal.
  • the device making it possible to ensure the passage of a load which must remain horizontal, such as a wagon transporting products requiring cooking, between an upper level and a lower level, according to the invention, is characterized in that it comprises a carriage provided with sections of rails, similar to those on which the wagon travels when it is at one of the upper or lower levels, in order to carry said wagon, said carriage being moved, by any suitable drive means, both vertically and horizontally in a movement during which said rail sections remain horizontal, between the upper level and the lower level.
  • the carriage is of triangular section and is arranged in a pit also having a triangular section so that the wheels of the carriage, carried by its oblique lower side roll along an inclined ramp oblique, the upper part of the carriage remaining horizontal during movement which brings the rail elements carried by the carriage from a higher position where they are in the extension of the rails outside the oven carrying the wagons, to a lower position or they are as an extension of the interior rails placed in the oven and submerged.
  • the trolley is provided with wheels situated on the same horizontal plane, the transition pit comprising as many inclined planes as there are sets of wheels, these inclined planes being parallel to each other so as to what the carriage moves while remaining parallel to itself.
  • the carriage no longer has wheels but is carried by a set of parallel connecting rods forming a deformable parallelogram.
  • FIG. 1 represents the general layout of a factory for manufacturing terracotta products such as brick tiles or the like.
  • a wagon 4 can have an area of around 40m2 and weigh 80 tonnes when loaded.
  • Factory 3 includes an oven 1 which can be of two kinds.
  • the oven 1 can be a drying and baking oven, in which case the products loaded in 32 are not dried before being loaded on the wagons.
  • the oven 1 can also be an oven in which only cooking is carried out, the drying of the products then being carried out in the manufacturing unit 31 before loading at 32.
  • the wagon 4 runs on a track 33 generally parallel to the oven 1. It is then taken over by a ferry 34 which transports it transversely, to one of the auxiliary tracks 35 intended for storage or up to 'to track 36 of the oven 1. When it arrives in the axis of track 36, the ferry stops and the wagon is moved on the rails 30 of this track. The wagon 4 is then driven in the oven 1 on the rails 10 thereof. These rails 10 are immersed in a pit filled with a liquid which can for example be water and are at a level lower than that of the rails 30 of the factory.
  • the wagon 4 At its exit from the oven, the wagon 4 is supported by a second transporter 37 which brings it either in the axis of an auxiliary track 35 or in the axis of the track 33.
  • a second transporter 37 which brings it either in the axis of an auxiliary track 35 or in the axis of the track 33.
  • the wagon When the wagon is back on track 33, it is unloaded at 38 from the cooked products which are conveyed to the shipping area 39 and then brought back empty to the loading area 32.
  • the zones 32 and 38 could be merged into one.
  • the auxiliary tracks 35 make it possible to remove a defective wagon but also to store throughout the week wagons of raw products which will be cooked during the weekend because it is absolutely out of the question to stop a cooking oven.
  • FIGS 2 and 3 show a first embodiment of the invention.
  • a ferry 34 which carries track elements 30a on which are the wheels 4a of a wagon 4.
  • This ferry is shown in the position where it is located opposite an introductory airlock 2 placed at one end of a tunnel oven 1.
  • This tunnel oven 1 comprises a pit F filled with water or other suitable liquid up to level E.
  • immersed rails 10 on which go rolling the wheels 4a of the wagons 4, these wagons being provided with skirts, not shown which plunge into the liquid, below the level E.
  • the pit F is extended at its two ends by a pit F ′, the bottom of which is constituted by an inclined plane 85 and which has a vertical wall 85a at its lowest end and an inclined flange 85b at its highest end.
  • This carriage has a chassis whose cross section is triangular, that is to say that it comprises a horizontal upper part 81, carrying sections of rails 80 intended to receive the wheels 4a of a wagon 4 and an oblique lower part 82, parallel to the bottom 85 of the pit F ′.
  • This oblique lower part 82 carries the wheels 84 of the carriage 8.
  • the carriage 8 is moved from the high position, shown in FIG. 2 to the low position shown in FIG. 3.
  • the rail sections 80 When it is in the high position (FIG. 2), the rail sections 80 are at the same height as the rail sections 30a of the transporter 34 and in their extension. When it is in the low position ( Figure 3), the rail sections 80 are at the same height as the rails 10 of the tunnel 1 and in their extension.
  • Figures 4 and 5 show a second embodiment of the invention.
  • the oven 1 is a tunnel oven in which the wagons circulate 4, charged with 41 batteries products to be cooked, on rails 10 immersed in a pit F filled with water or other suitable liquid.
  • E the level of the liquid in the pit F.
  • the wagons 4 are completely surrounded by a skirt dipping in the liquid at its lower periphery.
  • an airlock 2 which we see at 21 and 23 the locations of the doors. This airlock makes it possible not to put the oven in direct communication with the factory in order to allow the maintenance of the pressure or vacuum regime of the oven when a wagon 4 enters it.
  • the carriage 5 In the position shown in Figure 4, the carriage 5 is in its upper position for which the rails 50 which it carries are at the level of the rails 30 of the factory 3 and located in the extension thereof so that a wagon 4 can pass smoothly from the rails 30 to the rails 50 of the carriage 5.
  • the carriage 5 is formed, in the example shown, in FIGS. 4 to 6, of three beams 51 each supporting a rail 50.
  • the beams 51 are connected together by transverse beams 52 in order to form a frame whose solidity is further improved by beams 53 positioned to triangulate the assembly.
  • the carriage is provided with wheels 54 intended to allow its movement, these wheels being arranged in the same horizontal plane.
  • the numbers of wheels 54 and rails 50 of the carriage may be equal to the numbers of wheels and rails provided for the wagon although this is not essential.
  • Said wheels 54 move on raceways making it possible to bring the carriage 5 from the position shown in FIG. 4 to that shown in FIG. 5.
  • the raceways are formed of inclined planes 55 located in planes parallel to each other connecting at their upper and lower ends to horizontal planes 56, 57 respectively.
  • An inclined plane by axle or an inclined plane by wheel of the carriage can be provided. In any case, it will be necessary to carry out as many parallel planes as there are axles.
  • the carriage 5 thus passes, while remaining horizontal from its high position for which the wheels are on the horizontal planes 56 to its low position (shown in FIG. 5) for which the wheels 54 are on the horizontal planes 57.
  • the rails 50 are in the extension of the rails 10 of the oven 1 so that the wagon 4 can move from the carriage 5 to the oven 1.
  • the carriage 5 passes from one of its positions to the other by the action of at least one jack 6.
  • the jack 6 is hung at a fixed point 60 on the bottom of the airlock 2 at one of its ends and at a fixed point on the carriage 5 in the median plane of the latter at the other end.
  • the carriage 5 When, as shown, the carriage 5 carries three rails 50, it will be preferred to use two jacks 61, 62 whose attachment points are located symmetrically with respect to the median plane occupied by the beam 51.
  • Such a device has a very compact design, which makes it easier to produce a structure capable of supporting very heavy loads.
  • the use of the jack 6 ensures that the movement will be done at low speed and smoothly so as not to risk overturning the stacks 41 of products, this even with very inclined raceways in order to reduce the length of the horizontal displacement.
  • the rails 30 of the factory are in the extension of the rails 10 of the oven 1 while being at a higher level, this is why the carriage 5 moves horizontally in a direction parallel to the rails 30, 10 , 50.
  • An identical device is used in the airlock leaving the oven.
  • L 'assembly of the carriage 7 and connecting rods 71 form, seen in profile, a deformable parallelogram which passes from the high position shown in solid lines to the low position, shown in dotted lines.
