It carries a hydraulic cylinder 28 which extends vertically and whose piston moves a console 29 secured to a rod tray 25 support. This console is guided by a fixed vertical column 30 provided at its upper end of a stop plate 31.
  • Des drive means (not shown) can be mounted either directly on the frame 26 of the carriage, either on the transport route.
  • fig. 5 shows the relative positions of a processing element, such as that element 9 for example, and an oven, such as the oven 2, these elements also being visible at fig. 6.
  • the oven 2 comprises, conventionally, an insulating enclosure 32, heating bodies 33, an upper base provided with a fan 34 driven by a motor 35, a bell 36 and, at its lower opening, a plug 37 which is mounted on a support plate 38, itself articulated at the rear wall of the oven 2, and maneuverable by means of a jack 39 (fig. 6).
  • bell 36 will be fitted with internal elements protruding (361) and mounted on a movable support of so that it can be moved up and down rotating in an arrangement which is described in application EP 295 207 by the same applicant.
  • a space of height H (eg 100 mm) can be held between the oven and the tray.
  • Elements 7, 8, 9 and 91 (fig. 3) of the second together can be of different types.
  • the element 9, for example, is visible in Figures 3 and 5. It is a bin provided with insulating and waterproof walls 40. Its upper wall 49 has a square opening in which a cover 48. The interior space of this container is divided by partitions 41 into different zones to guide the circulation of the liquid contained in the bin. This circulation is controlled by pumps 50 (fig. 3).
  • a lift 42 (fig. 6), provided with a plate 43 of the same type that the plate 25, is led by a sleeve 44 on a fixed column 45 housed inside the enclosure.
  • This elevator is controlled by a cylinder 46 which is mounted vertically to the part back of bin 9, so that you can pass behind the group of ovens and upper elements 1 to 4.
  • the overall dimensions of these elements are shown in Figure 3.
  • the tray 9 is mounted by means of rollers 47 on the rails 5, so that it can be moved longitudinally on the transportation route. He can also commit under the upper transport track 10.
  • Element 9 is scheduled to run typically for a water or water quench tank oil.
  • the enclosure can still be fitted with heaters, so that maintain this oil at the desired temperature, by example 100 ° C or 200 ° C. If applicable, above of the liquid level, we can maintain a nitrogen atmosphere, so as to avoid oxidation parts and oil oxidation.
  • Element 91 is also provided with pumps 50.
  • the column guide 44 instead of being immersed in the enclosure, is separated from this enclosure and provided outside.
  • the actuating cylinder 46 is here arranged at the same height as the tank. It's about in this case a salt quenching tank allowing isothermal quenching.
  • Element 8 is, as shown in Figure 3, of the same construction as element 9, with however this difference that the pumps 50 are here absent. Although it is not shown in the drawing, the closing cover will be fitted insulation. On the other hand, the walls of the enclosure also have insulation thicker than that of tanks 9 and 91.
  • the element 8 thus constitutes a mobile furnace under controlled atmosphere and it is designed for example so that you can heat and maintain a charge at a temperature, for example of 1100 ° C.
  • element 7 the layout of which is practically identical to that of element 8, although that its dimension in the sense of the way of transport 5 is lower, this reduction in dimensions comes from the fact that the insulation of the walls of the speaker is reduced.
  • This item can work as a mobile handling bin under controlled atmosphere. It allows for example to transport a load between one of the furnaces of the top line and, for example, a processing element fixed such as those which will be described below.
  • FIGS 7-10 show two types fixed or mobile processing elements located in the bottom line, beyond the lane transport 5 and likely to be unloaded at of the handling equipment 11.
  • the upper transport track 10 which from the end of the line, i.e. from oven 1, and can be extended, if necessary, up to an unloading station or otherwise in depending on the number of fixed processing elements provided on the bottom line.
  • Element 17 is a high pressure gas tank. It is closed to its part upper by a cover 51. It includes interior partitions 52 intended to guide circulation gas inside the outer walls 53 of the bac. This circulation of gas is caused by a fan 54 actuated by a motor 55. Arrows 56 show the path of traffic some gas.
  • a mobile guidance system 69 allows reversing the gas flow to avoid deformation on the parts.
  • an elevator 57 which is of the same type as elevator 42 and is controlled by a jack 58.
  • the console of the elevator 57 is guided by a column 59 (fig. 8).
  • FIGs 9 and 10 show another construction of gas tank which can be housed either side of bin 17, in place of this element.
  • Bac 60 represents a construction of low pressure tanks also allowing ensure the progressive cooling of the gas and, therefore, a controlled variation in the charge temperature maintained within the item.
  • the cooling elements located inside the tank. This last one is closed at the top with a square cover 62 and it includes an elevator 63 likewise construction as the elevator 57 but whose console is oriented slightly obliquely.
  • the guide column 64 is located at an angle of the enclosure and the actuator actuator 65 of the elevator is located on the upper side of the tank.
  • the gas circulation is ensured by a fan 66 with vertical axis, located in the bottom of the tank and driven via a belt 67 from a motor 68 which, as seen in Figure 10, is housed in the rectangular bulk of the walls outside of bin 60.
  • a charge taken by the tray 25 of the industrial truck on one of forks 23 integral with the carousel 20, can be moved on transport track 5, so that bring it below one of the ovens 1, 2, 3 or 4.
  • the oven having been opened beforehand by tilting from its cap 37, the charge can be introduced, for example, into the bell 36 of the oven 2 (fig. 5) which, by a lowering maneuver and rotation, brings the projections it presents on its periphery in positions below of the angles of the frame 24. It is therefore sufficient lower the elevator console 29 so that the plate 25 releases the frame 24 from the load and keep the latter subject to the bell 36.
  • the oven can be closed and the desired heat treatment started.
  • all operations transfer and displacement are relatively time-consuming operations very short compared to treatment times proper. So after you set up a load in an oven such as 2, the cart can easily come and look for another charge in the entry station, to bring it for example in the washing station or in another of the ovens.
  • the fork of the handling 11 can be inserted under the load and thus take up the latter, which frees the trolley 6. From there the load can be transported either in an unloading station (not shown), located at the end of track 10, i.e. transferred to one of elements 17 or 60. Then it can be picked up by machine 11 and transferred back to cart 6 which will take it back to the entry station 20.
  • unloading station not shown
  • machine 11 can be picked up by machine 11 and transferred back to cart 6 which will take it back to the entry station 20.
  • the installation described allows all possible variants of handling, transfer and transport of loads, and this with a space requirement minimized and the possibility extend the installation by adding elements additional, either in fixed locations next to the bin 17, either on the transport track 5, also in the upper line of the ovens.
