Definitions
- the present invention relates to a detection device an obstacle for a handling door or a roller shutter and a handling door or a roller shutter fitted with a such device.
- Detection devices which include one or more opto-electronic cells arranged in the door or shutter jambs or rails, these cells being able to inhibit the functioning of the drive system shutter or door when an obstacle is in in front of them.
- this or these cells are not capable of react only when the obstacle is directly in front of them, which results in imprecision of the detection device and in possible maneuvers of the shutter or the door when the obstacle is located below or above the cell.
- switches and operating fingers include moving parts which must be able to move under load, especially under the weight of the soft strands of the roller shutter, so that these are likely to get deform due to the fatigue of the materials used. These parts must therefore be provided robust, which increases their cost price and harms overall economic performance of the device.
- the invention aims to solve these problems and to propose a effective detection device, i.e. capable of reacting regardless of the position of an obstacle under the apron flexible and having no part in contact with the apron, so there is no risk of breakage or deformation of these parts.
- the invention relates to a device for detection of an obstacle preventing the operation of a flexible apron of a handling door or a shutter rolling, characterized in that it comprises a opto-electronic detection arranged near the shaft curtain winding outside the winding area of this apron.
- the invention no part of the detection is not likely to be in contact with the apron, so any risk of breakage or fatigue wear can to be avoided.
- the position of the deck around its winding shaft and, in particular, the possible formation of a strand slack is detected by the opto-electronic cell which is placed out of reach of the deck and therefore does not risk being damaged.
- the cell is oriented to aim in a direction parallel to the winding shaft. Thanks to this aspect of the invention, the unit is able to react as soon as part of the deck interrupts a wave beam oriented parallel to the shaft winding.
- the cell is of the transceiver type and cooperates with a reflecting device located opposite the cell to outside of the deck winding area. Thanks to this aspect of the invention, a single cell located on one side of the apron is sufficient to constitute a device for effective detection.
- the invention also relates to a handling door or a roller shutter equipped with a detection device such as previously described.
- a handling door 1 comprises a flexible curtain or apron 2 which can be wrapped around a substantially horizontal shaft 3, this tree being driven in rotation by an electric motor not shown.
- the door also includes two lateral uprights 5 and 6 each forming a vertical slide of which only one 7 is visible in Figures 2 and 3.
- a load bar 8 is arranged at the lower end apron 2.
- an opto-electronic cell 10 is arranged on the upright 6 near the shaft winding 3, outside the winding area of the apron 2.
- cell 10 is protected against movement of the apron 2.
- the cell is oriented towards a device reflective 11 arranged on the upright 5 opposite the cell 10 and outside the deck winding area 2.
- the reflecting device 11 is also out of reach of the apron 2.
- Cell 10 is of the transmitter-receiver type, so that it emits towards the reflecting device 11 a beam F of light, infrared, ultra-violet rays or of any other suitable type, which it receives back after that it has been returned by device 11.
- the detection device of the invention is effective regardless of the height of the obstacle 13, which is a significant advance over devices with an optoelectronic cell located in or near one of the slides 7. Furthermore, like no other part mechanical is not likely to be moved by the deck 2, it is not necessary to provide a protective cover for insulate such a room from the ambient atmosphere, especially when the door is installed inside a industrial premises. Indeed, cell 10 and the device reflective 11 are able to work in any that it atmosphere and do not see their characteristics altered by a deposit of dust.
- the device comprises several distributed cells around the winding shaft, as it appears with the 10 'and 10 "cells shown in phantom in the figure 3. These 10 'and 10 "cells cooperate with cell 10 to detect the formation of a soft strand equivalent to the soft strand 2a in different angular sectors around the tree 3, of so that the device is able to react as soon as a soft strand and without waiting for it to develop so important to the point of passing in front of a cell arranged in a particular angular sector. This helps improve the response time of the detection device of the invention.
- a handling door or a roller shutter fitted with a detection device according to the invention is therefore safe insofar as he or she comprises a device capable of react regardless of the height of the obstacle 13 and which does not not likely to be damaged by a shock due to the apron in progress winding or wear of the parts in contact with it apron.
