Description

Operating procedure of an automatic sliding door installation.

The invention concerns a method of operating an automatic sliding door installation according to the preamble of claim 1.

5 Document DE 196 53 026 A1 is known for an operation procedure of an automatic sliding door installation with at least one sliding leaf that is operable by means of a drive device activated by an electronic control device. A surveillance zone which, when opening the sliding leaf, is exceeded by a vertical secondary closing edge of the sliding leaf, is monitored by a sensor device, for which purpose the sensor device, when an obstacle occurs in this surveillance zone, send a signal from

10 indicating obstacle of this state to the control device, which causes immediate braking and stopping or an immediate reversal of the sliding blade during normal operation. The sliding door installation can be installed on an escape and rescue route because the drive device is designed so that, in case of emergency operation, the escape and rescue route can be released, after activation of the control device with an emergency signal, such that the blade

15 slider be moved by the control device from its closed position towards its open position. The obstacle signal is of a higher range than the emergency signal, that is, the immediate braking of the sliding blade also occurs when the emergency signal occurs. However, this may mean that the achievement of a minimum required opening width of the door within a predetermined maximum time is not guaranteed in all cases.

20 Document DE 10 2004 031 897 A1 is known, which represents the closest state of the art, another operating procedure of an automatic sliding door installation. When a signal indicating an obstacle appears in the surveillance zone which, when the sliding leaf is opened, is passed by a vertical secondary closing edge of the sliding leaf, the sliding leaf is braked by the control device in a braking phase , after passing through the acceleration phase and a shortened high speed phase, until a low

25 smaller speed and said sliding blade moves with this low speed to its fully open position. These procedures certainly guarantee the achievement of a minimum required opening width of the door within a predetermined maximum time, but there is a residual risk that obstacles are reached and eventually caught by the secondary closing edge of the sheet Door that moves with low speed.

The invention is based on the problem of creating an operating procedure of an automatic sliding door installation that guarantees both a reliable release of the escape route and a minimization of the danger from the sliding leaf being opened.

The problem is solved with the features of claim 1. The dependent claims form advantageous embodiments of the invention.

35 When the obstacle signal is produced while the emergency signal is present, the sliding leaf is deliberately braked until it is stopped at a stop point, the stop point being authorized only in 80% of a predetermined minimum opening width for an installation of Sliding door usable in an escape and rescue route or between 80% of the minimum opening width and the fully open position. The sliding door is not braked immediately when the obstacle signal occurs, but continues to operate at

40 principle in the opening direction until one of the above criteria is met.

In this way, a reliable release of the escape route is guaranteed as well as a minimization of the danger from the secondary closing edge of the sliding leaf that is being opened, since, despite an obstacle signal that eventually arises, the opening movement is continued, that is, the release of the escape route, preventing the stopping at the point of detention from trapping the obstacle and enabling

45 clearing of the danger zone of the secondary closing edge. The stop point is reached until the end of a maximum time that is set in a sliding door installation that can be used in an escape and rescue route and in which the sliding leaf must have reached at least the minimum opening width.

To enable the clearing of the area to be exceeded by the secondary closing edge, the sliding door leaf moves with a smaller low speed to its fully open position only

50 after a preset stop time has elapsed, for example after a 15-second stop.

In case the stop point is already located between the predetermined minimum opening width and the fully open position, this final full opening can eventually be dispensed with.

In the event that the sliding blade stops at a stop point between 80% and 100% of the preset minimum opening width, the sliding sheet must move at least to its minimum opening width 55 after the end of the downtime, but you can stay here, meaning you don't have to move to

Your position completely open.

In the following, examples of embodiment are explained in more detail with the aid of the figures in the drawing.

They show in these:

10 Figure 5, the velocity curve as a function of time when opening the sliding leaf in an emergency operating state.

Figure 1 shows an automatic sliding door installation 1 with two sliding leaves 2 and two fixed fields

3. The sliding blades 2 are operable by a drive device 4 arranged on the sliding blades 2 and the fixed fields 3, for example activated by a sensor (not shown) that captures the approach 15 of a person. The sliding leaves 2 have approximately the same width as the adjacent fixed fields 3. The sliding door installation 1 is suitable for use in an escape and rescue path, for which purpose the actuator 4 is designed so that, after activate the control device with an emergency signal that can be generated, for example, by a smoke or fire alarm or by a manually maneuvering emergency button, the sliding leaves 2 are opened such that these leaves

20 slides 2 reach within a predetermined maximum time (for example, 3 seconds) a predetermined minimum opening width XM (for example, 80% of the full opening width).

In figures 2 to 5 the speed V of the sliding blades 2 is shown as a function of the opening width X of these (figures 2 to 4) and as a function of time t (figure 4) for the opening movement thereof in the case of an emergency opening of the sliding door installation 1. The closed position of the sliding doors 2

25 has been designated with the opening width X0 and the fully open position of the sliding blades 2 has been denoted with the opening width X2. The maximum speed of the sliding blades 2 has been denoted with v2. In the first embodiment according to Figure 2 the minimum opening width XM of the sliding sheets 2 is equal to the full opening width X2, while in the second embodiment according to Figures 3 and 4 the minimum opening width XM is smaller than the full opening width X2.

30 In the event that no obstacle is found in the surveillance zone of the sensor device 5 that monitors the secondary closing edges of the sliding blades 2, said sliding blades 2 travel the designated speed curve with the reference symbol 7, that is to say that in the acceleration phase s1 the sliding blades 2 are accelerated within the acceleration time t1 up to the instant T1 passing from the stopped state to the high speed v2, which is retained by them in the high speed phase s2 during the High speed time t2 until instant T2. Follow

35 a braking phase s3 in which the sliding blades 2 are braked within the braking time t3 up to the instant T3 passing from its maximum speed v2 to the stopped state and have then reached the maximum opening width X2. In this way, the fastest possible opening of the sliding leaves 2 is guaranteed in the case of an emergency opening of the sliding door installation 1, safely complying with the slogan that the sliding leaves 2 reach the minimum opening width required XM within a while

40 preset maximum.

However, in the event that an obstacle is found, especially a person, in the surveillance zone of the sensor device 5 which monitors the secondary closing edges of the sliding blades 2, the sensor device 5 generates an obstacle signal and the Sliding blades 2, while the emergency signal is present, travel the speed curve designated with the reference symbol 8. This curve corresponds to the speed curve 7 of the speed curve 7 of the unimpeded movement. However, the phase traveled with the maximum speed v2 is limited to a shortened high speed phase s4 which is traveled in the shortened high speed time t4 to the instant T4 and to which it joins - rather than with the speed curve 7 of unhindered movement - the braking phase s5 traveled within the braking time t5 up to the instant T5. After passing through the braking phase s5, the speed of the sliding blades 2 at a stop point X1 is reduced to zero. The position of the stop point X1 must be at least 80% of the minimum opening width XM. It is essential in this regard that the acceleration phase s1, the shortened high-speed phase s4 and the braking phase s5 are traveled within the predetermined maximum time, for example 3 seconds, so that at least the width is then safely reached Minimum opening required XM of the sliding blades 2. The sliding blades 2 remain at stop point X1 for a preset stop time t6. Within this time it is possible

clear the area that must be exceeded by the secondary closing edge of the sliding leaf 2.

In the exemplary embodiment according to Figure 2 the minimum opening width XM corresponds to the fully open position X2, that is to say that the stop point X1 is located at 80% of the minimum opening width XM. Following the described stop, the sliding leaves 2 must continue moving, then

5 after the stop time t6 has elapsed, until its fully open position X2 to reach the minimum opening width XM. This movement can be performed with the low speed v1 in a low speed phase s6 within the low speed time t7. Shortly before reaching the fully open position X2, braking is carried out starting from the low speed v1 along the velocity curve 7 of the unimpeded movement, whereby, upon reaching the maximum opening width X2, the leaves are braked sliding to stop them.

10 In the exemplary embodiment according to Figures 3 and 4 the minimum opening width XM is smaller than the fully open position X2.

In the movement curve according to figure 3 the braking of the sliding blades 2 is carried out so that the stop point X1 is at 80% of the minimum opening width XM, that is, after the stop time has elapsed t6, the sliding blades 2, once the stop time t6 has elapsed, must continue moving at least

15 to its minimum opening width XM. Sliding blades can be stopped here again to lessen the danger of obstacle entrapment, but, as an alternative, they can also be brought to their fully open position X2 along the 8 ’speed curve represented by dashed lines.

In the different movement curve according to figure 4, the braking of the sliding blades 2 is carried out so that the stop point X1 is presented with the full minimum opening width XM, that is to say that after 20 the stop time has elapsed t6, the sliding blades 2 do not have to continue moving at least to their fully open position X2, that is they can be moved during the low speed time in the figure

5. However, as an alternative, the sliding blades 2 can also be brought here to their fully open position X2 along the velocity curve 8 'represented by dashed lines.

During normal operation, the opening movement of the sensor device 5 can also be monitored

25 the sliding leaves 2 of the sliding door installation 1, that is, during the opening of the door leaves activated by the approach of a person, and said opening movement can be carried out with the same speeds as previously shown.
