Definitions
- the present invention relates to a device for the detection of a obstacle preventing the proper functioning of a material handling door flexible apron.
- detection devices which are designed to actuate lifting the door when it encounters an obstacle during its descent.
- the devices are housed under the threshold bar which is made of metal.
- the devices consist of a probe system pressure applied continuously across the width of the bar threshold.
- the elongated envelope has a channel over its entire length which contains at its opposite ends a transmitter and receiver for a ray which runs parallel to the edge free from the flexible curtain. As soon as the envelope undergoes a slight deformation, the beam is interrupted, triggering the stopping of the movement of La door.
- the obstacle cannot be detected by the detection devices such as the pressure sensor located on the threshold bar.
- Patent CH-A-548,523 discloses a device for detecting a obstacle in which two switches are arranged respectively above and below the winding shaft of a roller shutter. Each switch is associated with an operating finger and a spring, hence a complexity of the device. In addition, this device is not suitable for react to the formation of a loop only opposite the operating fingers a switch, i.e. above or below the shaft winding. Indeed, the fingers are sensitive over a small range angular with respect to the winding axis of the shutter. If a loop or a soft strand forms in an area away from the fingers, the device does not reacts only when the loop has grown in such a way that it reaches one of the fingers, this can happen well after training of the loop. The security function sought with the device is therefore not fully achieved.
- the invention relates to a device for detecting an obstacle preventing the smooth operation of the flexible deck of a handling door, comprising detection means arranged at proximity to the horizontal tree around which the apron winds flexible, said detection means being connected to a position controlling the rotation of the horizontal shaft, characterized in that the detection means consist of at least one strap which has a substantially curved profile and arranged perpendicular to the horizontal shaft, said strap being connected on the one hand to the position switch and on the other hand to a fixed blade or to one face of a cover secured to side uprights.
- the device can react effectively to a obstacle on the path of the roller shutter by the detection of the formation of a loop over a wide angular range with respect to the axis of the door winding shaft.
- the use of a strap guarantees that the formation of a loop does not deform by the articulated lever of the switch because the strap absorbs variations in the volume of the apron.
- the fixed blade and the switch of positioning are fixed perpendicular to each other to inside a hood. So the strap extends over a higher angle at 90 °, which makes the device effective over an angular range.
- the strap has a substantially curved profile. Thanks to this aspect of the invention, the strap is shaped to receive a loop formed by the shutter deck when relaxed.
- the switch position has a lever that swings under the effect of the tension of the strap.
- the lever which controls the switch is not at contact of a soft strand formed by the apron and not likely to be deformed by an effort due to such a soft strand.
- a handling door 1 comprising a flexible curtain or apron 1 a windable around a horizontal shaft 1 b which is rotated by means of a not shown gear motor.
- the handling door 1 is made up of lateral uprights 1 c comprising a vertical slide 1 d in which the flexible apron 1 a slides.
- the latter comprises at its lower end a threshold bar 1 e known per se.
- the handling door 1 has in its upper part a cover 1 f integral with the uprights 1 c and which can be provided over the entire width of the shaft 1 b .
- each upright 1 c is provided a fixed blade 1 g directed in the direction of the horizontal shaft 1 b .
- the fixed blade 1 g is arranged below the shaft 1 b and close to it.
- the cover 1 f comprises on one of its internal faces and more particularly on those located perpendicular to the fixed blade 1 g a position switch 1 h which is electrically connected to the gear motor driving in rotation the horizontal shaft 1 b .
- the position switch 1 h comprises an articulated lever 1 i which is secured to a flexible strap 1 i , the opposite end of which is fixed to the extreme end of the blade 1 g , that is to say below of the horizontal tree.
- the strap 1 j affects a slightly curved profile passing below and near the horizontal shaft 1 b .
- another strap 1 j can be mounted at the other end of the shaft 1 b of the handling door 1.
- a variant of a detection device according to the present invention has been shown, which consists in that the positioning switch 1 h receiving one of the ends of the flexible strap 1 i is fixed on the lower face 1 k of the cover 1 f.
- the other end of the flexible strap 1 i is directly secured to the upper side 1 l f of the cover 1 so that said strap is perpendicular and adjacent to the horizontal shaft 1b of the handling door 1.
- the flexible deck 1 a encounters an obstacle either under the threshold bar 1 e , or laterally as represented by the arrows F1 and F2 in FIG. 3, it can be seen that the unwinding of the shaft 1b forms a soft strand 1 ' a which bears against the strap 1j of the safety device.
- the movement of the safety strap 1 j causes the lever 1 i to tilt, actuating the positioning switch 1 h .
- the strap 1 j is capable of receiving the soft strand 1 ′ a , as shown in FIG. 3, over a wide angular sector and therefore to activate the switch 1 h via the lever 1 i
- the position switch 1 h controls the geared motor so that it immediately drives in opposite direction.
- the shaft 1 b for reassembling the flexible deck 1 a .
- the slack side 1 During the ascent of the flexible apron 1a, it is found that the slack side 1 'disappears and allows the strap 1 j to return to its initial position.
- the return to the initial position of the strap 1 j releases the lever 1 i which is loaded elastically to return to its original position.
- the gear motor again changes direction of rotation so that the deck 1 a can descend without encountering an obstacle.
