Definitions
- the present invention relates to a closure system for cold stores; which, of the type that includes an insulating access door that establishes a closure when acting against a perimeter frame mounted at the entrance of the chamber, and a rapid opening door designed to minimize temperature changes while the door remains open camera access isolator; it presents some constructive peculiarities that allow the quick opening door to be integrated into the frame of the insulating door by closing the chamber together with it; being, however, its actuation means outside the chamber.
- the cold rooms have a perimeter frame in the entrance holes on which an insulated access door closes.
- Some of the most used solutions to solve this problem are based on the use of slat curtains formed by a plurality of sheets of material plastic, in the automation of the insulating door, which does not have a high opening or closing speed, or in the use of fast opening doors, which facilitate access to the chamber and at the same time reduce the exposure time of the chamber at the external temperature due to its high opening-closing speed.
- the sheet curtains are placed in the chamber's entrance opening, forming a barrier behind the insulating access door; These curtains when pushed by people, wheelbarrows or any other element, allow entry or exit of the camera.
- the quick-opening doors are composed of a sheet, flexible or rigid, which when moved by means of actuation produces the opening or closing of the access hole.
- Patent FR-A-2,747,182 concerns an exclusive cold storage chamber in which the use of a rapid door consisting of a laminar element with reinforcement cross-members, such as those explained, placed in front of or behind the rear is provided. insulating door for access to the sluice or cold chamber, operated by a maneuvering system that can be picked up on a drum, said system and drum being installed outside the sluice and the cold chamber to which it gives access.
- the closing system for cameras has been devised that, taking advantage of the automatic fast-opening doors, allows the assembly of the actuation means thereof, outside the chamber, with the sheet being closing between the insulating access door and the chamber or vice versa and being able to take advantage of the insulating door frame for quick door guidance.
- this closure system is of the type comprising: a perimeter frame mounted on the entrance of the chamber, an insulating access door that acts on the outer side of the frame forming the closure of the chamber and a sheet that, conveniently actuated, effects the opening or closing of the chamber access opening, the sheet assembly and its motorization forming a quick opening door designed to minimize the variation of temperature inside the chamber while the chamber remains open insulated access door to it.
- the system of the invention has the peculiarity that the perimeter frame From the entrance to the chamber there is an anterior and a posterior portion protruding from the wall of the chamber, the sheet of the rapidly opening door sliding through one or more grooves located at any point of the threshold of the frame.
- the sheet collection system is conveniently mounted by means of a support structure on the outside of the cold room, and arranged parallel to that side of the frame provided with the slot for the passage of the sheet
- the system includes a sealing device for closing it.
- Said sealing device may be composed of profiles integral to the sheet, a device operable by the insulating access door or the sheet itself, an automatic device actuated by external elements or flexible profiles mounted on the slot itself and which Act permanently on the sides of the sheet without preventing its displacement.
- the system may include heating means intended to prevent the formation of ice both in the mentioned groove and in the guides of the sheet, since this could prevent the correct operation of the fast opening door.
- FIG. 1 shows a front view of a refrigeration chamber provided with the closure system object of the invention and in which the sliding guide of the insulating access door has been partially shown.
- two sections have been made on the frame to allow the observation of the heating means of the groove and of the lateral guides.
- FIG. 2 shows a profile view of the closure system sectioned by a vertical plane that passes through the middle area of the entrance to the chamber
- FIG. 3 shows a schematic view of the bars of the sealing device disposed one on each side of the flexible sheet and slightly spaced vertically from the frame.
- FIG. 4 shows a detail of an embodiment variant of the sealing device of the groove for the passage of the sheet.
- FIG. 5 shows a detail of another variant embodiment of the sealing device of the groove for the passage of the sheet.
- the closure system object of the invention has a frame (1) mounted on the inlet opening (2) defined in the wall (3) of a cold store, whose interior is indicated by the reference (4).
- An anterior portion of the frame (1) protrudes, towards the outside of the chamber (4), of the plane defined by the wall (3), being fixed to said frame a guide (5) on which an insulating access door (6) moves, responsible for establishing the closure of the chamber (4) when facing the frame (one).
- the frame (1) has, in the upper portion of the wall (3), a longitudinal groove (7) for the passage of a flexible sheet (8) that is associated with a rotating drum (9) on which It is wound or unwound depending on the direction of rotation of an engine (10) acting on it.
- the sheet (8), the drum (9) and the motor (10) form a quick opening door whose purpose is to minimize the variation of temperature inside the chamber (4) for as long as the door remains open access isolator (5).
- the motor (10), in charge of winding the sheet (8) in the drum (9), can be driven by different systems, which have not been represented because they do not consider its description of interest.
- This slot (7) is It may contain inside heating elements (71) that prevent the formation of ice due to the difference in temperature between the inside and outside of the chamber.
- the slot sealing device (7) is schematically represented by two parallel bars (14) that are arranged on the upper side of the frame (1), one on each side of the groove (7) and, therefore, one on each side of the sheet (8). At least one of these bars (14) can be displaced by the action of a drive mechanism (15) that causes the approach of both bars (14) and the closing of the groove (7).
- the groove sealing device (7) is represented by two profiles (12) fixed on the sides of the sheet (8).
- the sealing device is formed by flexible profiles (13) fixed to the sides of the groove and acting permanently on the sheet (8) without preventing its displacement.
- guides (16) for guiding the sheet (8) in its displacement towards the opening or closing position are defined. These guides may have heating means (161) to prevent, if necessary, the formation of ice thereon.
