Abstract

The invention relates to a device which is used to detect the force applied by the drive (2) during the movement of industrial doors (1), wherein a force-detecting component (16) that determines a force curve (15) for each run of the industrial door (1) is associated with the door controller (4) or with the drive (2). Said force curves (15, 22) are stored in a memory (17) and can be used for comparison with the subsequent force curve (18, 23) in order to thus detect possible hazardous situations and to switch the drive accordingly. The force-detecting component (16) then ensures that, in the case of upward movement initiated by the push-button switch (10) and occurring divergences between the force curves (15, 18), the industrial door (1) is stopped, while in the case of downward movement initiated by the push-button switch (11, 25), downward movement can be performed anew from the upper end position, to which the industrial door is automatically reversed. If a divergence of the force curves then occurs again, a new force curve can be determined anew by means of the push-button switch (11, 25), which is then connected in a dead-man's circuit. The new force curve is then the starting point of the further operation of such an industrial door (1).

Description

DESCRIPTION

Force recognition device for industrial doors

The invention relates to a device for detecting the force applied in the process of industrial doors from the drive, consisting of the

Process of industrial gate monitoring and controlling door control. The invention also relates to a method of operating an industrial door with the aid of a door controller associated with the drive moving the industrial door with measurable force.

In known industrial doors, especially sectional, rolling, high-speed, cover folding, side folding doors and sliding doors, a so-called force detection is known, for which complicated spiral cables, tedoses, optical sensors and slack rope switches are necessary. Another disadvantage is that this known force detection, if it is ever used, is very susceptible to failure, because of recognized problems, the industrial door stuck and then a

Craftsman or a maintenance technician must be consulted in order to solve the problems encountered. Since the maintenance technicians are usually specialists, these are not immediately available for such companies and downtimes can not be avoided.

The invention is therefore based on the object in the operation of

To provide industrial doors with effective and safe force detection and associated equipment.

The task is gem. the invention achieved in that the drive a determining a force curve at each trip of the industrial door

Force detection component is assigned, at the same time this force curve with the im Memory stored, comparing previous power curve and the drive is influencing adjustable when detecting a dangerous situation.

Thus, first of all, a device is made available which gives the possibility to get along with the actually available components and to enable a precise determination of the applied force by adding a corresponding software or the corresponding force detection component, which is also new that this to be determined force is recorded in the form of a force curve and stored in a memory, so that it is comparable to the following force curves. If differences then occur and a dangerous situation occurs, the drive is either reversed as before, ie. H. moved to the upper end position or stopped; the latter in the upward journey. How best to recognize one

Danger situation then bypasses, is taught further back. First of all, it is important that the dangerous situation can be properly identified without the need for expensive ancillary equipment. In addition, it is advantageous that not only certain values are determined by determining the force curve, but also the change in the values, which is important for determining the dangerous situation.

In an expedient embodiment of the invention, it is provided that the force detection component is designed to detect the dangerous situation via an impermissible increase in the force or the force curve, wherein this point of impermissible increase of the force curve is adjustable. With such an embodiment, it is advantageously possible to determine a force curve via the force detection component-where a frequency converter or the like is suitably used as the force detection component. It is, not only the

Force curve measurable, but it can also be specified exactly at which limit the door control is "informed" accordingly.

After another appropriate training is

Force detection component adjustable between 1 and 100% increase in force. Either When driving up the gate as well as when driving down the gate is always a certain increase in force recorded, so it would not be advantageous if the door control would be activated even with a small increase in power. As a rule, at 30% or 50% increase in strength, this will be the

Force detection component controlling the gate control form or set.

In order to be able to bridge any strong force increases, the

can occur, for example, in the slight jamming of the industrial gate, it is advantageous if the driving the industrial door drive is equipped with an automatically switchable reserve driving force. Due to such equipment of the drive can be controlled in the short term, such increases in force.

It is optimal if, as proposed by the invention, the

Gate control the upward drive and the downward trip triggering buttons

are assigned, which are assigned to a rule to be reached from the ground control box and wherein the downwards triggering button at

repeatedly recognizing a dangerous situation in Totmannschaltungsbetrieb switching is formed. While at the first recognition of a

Danger point or a dangerous situation, the industrial door is simply brought down again to read a new force curve, the dead man operation gives the possibility, even with then again reversing goal the danger point either accurately identify and identify or the gate by continuous operation the push-button triggering the downward movement to bridge the "small" danger situation, the

determine appropriate force curve and then ensure trouble-free operation of the industrial gate. Only then, if by perpetual

Reversing the industrial door on the descent is made clear that a "special" damage is present, you will turn on a maintenance technician willy-nilly. When driving uphill, problems can be caused by something hooked to the gate, or for example, a child has hung himself and can be pulled up with. To prevent this, the looks

Invention, that the door control when operating the upward trip triggering button when detecting a dangerous situation, the industrial door is executed immediately stopping the software. Thus, a collection security is realized, which meets the legal and regulatory requirements.

The danger determined by the force detection component or

Impairment of the industrial door should also be made clearly recognizable, which is provided that the drive and the

Gate control receiving box and the control box assigned a signal light and control technology connected to the door control or the force detection component. The force detection component thus responds to the gate control and at the same time the signal lights, so that the

User is warned in a timely and accurate manner. Of course, an acoustic signal and a corresponding encoder is possible or the use of both signal devices. The force detection component is adjustable with respect to the increase of the force, as stated earlier. For larger changes in the door behavior, however, the otherwise automatic control algorithm can no longer be influenced, ie. H. the force detection component is executed with respect to the force detection from the outside uninfluenced.

Even with loss of power, the last power curve can be stored in memory and recognized because gem. the invention of the memory itself is designed as a nonvolatile memory. This satisfies the TÜV regulations in an advantageous manner.

An industrial door can gem. the invention are operated to solve the task so that the drive is equipped with a force detection, via which the force applied by the drive is measured at each drive of the industrial door and stored in the form of a force curve in a memory with the following force curve comparably, wherein when comparing the force curves exceeding predetermined limits is recognizable, the force detection the door control when reversing to reversing and, if necessary, repeating the descent and when reaching the limit again

Dead man's circuit is switched, while uphill a stop is performed by the gate control upon reaching the limit. Thus, with respect to the upward movement, the security is given that objects hooked to the door or even a person attached to it are not put in danger because the industrial door is immediately stopped. The impairment can then be remedied and the operation of the industrial gate resumed. In the more critical descent, upon detection of a limit, i. H. if the force curves deviate too much, after the reversing, which is then automatically occurring, ie when the industrial gate is raised again, the descent will be resumed. If reversing occurs again because the corresponding force limit value is reached, it automatically opens

Dead man's circuit switched, d. H. the corresponding button for the downward movement can now lead by continuous pressing that the industrial gate continues to move downwards and crosses the limit, so that at the same time a new force curve results, then the problem-free continued operation of the

Industrial doors ensure. Only if on further downhill

automatically reaches a limit again and the industrial door is reversed, the maintenance service must be turned on.

In order to further optimize the operation, the invention provides that when predetermined limit values are exceeded, this is indicated optically and / or acoustically. As a result, a certain additional warning occurs, which makes it possible for the operator to quickly and reliably recognize the problem that has arisen and then try to remedy or remedy the problem as described. As already mentioned above, it is advantageous if when detecting a problem in the downward drive by the force detection, the existing power curve is re-taught by pressing the deadman, as far as the problem is manageable deadman. Through this procedure, problems that have occurred by burping the industrial door on any objects or on a person can be easily detected and corrected, only if then reversing automatically occurs again, a problem that can not be repaired without repair exists. The invention is characterized in particular by the fact that a

Device and a method are created, with which it is possible to operate large and small industrial doors with an effective force recognition without much effort and in particular costly installations. Above all, the described deadman circuit is given the opportunity to operate such industrial doors with an effective force detection, which is useful and necessary to use in a sectional door or similar gates, since there the springs or the spring force after a certain number of

Opening operations changed or the rollers and hinges

can become difficult. About the force detection gem. The invention continuously determines an adapted force curve and stored in the memory, so that these "creeping" resulting problems are no longer because the corresponding force curve not the occurred impairments

considered in principle. If, on the other hand, an additional problem occurs or a problem occurs, the force recognition or the force detection component comes into action when comparing the force curves in the case of large divergences, and then enables further operation if it is a

correspondingly low problem. When driving over or passing through this small obstacle, the force detection component reads a new force curve that takes this into account so that the industrial door can be operated again. If there are more, because of bigger problems, then a maintenance technician has to be switched on. Thus, the number of problems is much lower than in previous force detectors and above In addition, all safety regulations are fully taken into account and can be effectively observed.

Further details and advantages of the subject invention will become apparent from the following description of the accompanying drawings in which a preferred embodiment with the necessary details and individual parts is shown. Show it:

FIG. 1 shows an opened industrial door,

Figure 2 shows the arrangement of the drive with gate control and

Force sensing component,

Figure 3 shows the control box with the necessary to operate the industrial door and buttons

Figure 4 different force curves for the up and down travel.

FIG. 1 shows an opened industrial door 1 which has been raised to this position via the drive 2 (not visible here). The non-recognizable drive 2, the gate control 4 is assigned. At the upper edge of the door opening a Radarfühler 5 is positioned and at the lower edge 8 of the industrial door 1 sensors 6 are mounted so as to be able to open the industrial door on arriving vehicles in a timely manner.

Above the bottom 7, a control box 9 is mounted on the inside or on the outside of such a door, the various buttons are assigned, which will be explained in more detail with reference to the description of Figure 3.

The industrial door 1 moves within the door opening and guided by Torständer 20th

FIG. 2 shows the arrangement of the drive 2 above the industrial door 1. The drive and the associated door control 4 are in a box. 3 accommodated. In the same housing part in which the door control 4 is fixed, a force detection component 16 is also accommodated, via which the force required for ascending and descending the industrial door 1 is determined and held in the form of a force curve. These force curves 22, which are shown in FIG. 4, are stored in a memory 17 after being determined, so that they can each be compared with the new force curve 23. Due to the occurring values, problems can be identified by the comparison and, as explained further below, can be remedied. On the box 3, a signal light 19 is attached, which occurs as well as the control box 9 associated

Signal lamp 12. This will alert the user or owner that there are any problems.

Figure 3 shows the control box 9 in plan view, wherein it can be seen that a button 10 for the upward movement and a second button 1 1 for the

Downward movement of the industrial door 1 are provided. In addition, the already mentioned signal light 12 is present, which alerts the user that any problems may exist.

When you press the button 10, the industrial door 1 moves to the top

End position, while z. B. the force curve 15, which is shown in Figure 4, is determined. If this is now a certain amount above the previous force curve 18, as shown in Figure 4, this is indicated by turning on the signal lights 12, 19 and causes either the industrial door 1 reversed, that is moved into the upper end position or when driving uphill is stopped. The latter is the case when the force curve 22 is significantly different from the force curve 23.

Occurs when driving further down after pressing the button 1 1 again a situation of the force curves 22 and 23, and the industrial door 1 is driven back to the upper end position, a further operation can only be done via the then deadman circuit located button 1 1, then serves as deadman button 25. Only with continuous pressure, it is then possible, the industrial door 1 again lower and determine a new force curve. Is this possible, ie

reached the industrial door 1, the lower end point of his career, can be driven with the then new force curve 22, as far as no further problems.

Advantages are thus that the industrial door 1 can be restarted without a separate or specialized technician, if

The force detection component 16, ie, for example, a frequency converter, ensures that a new force curve 15, 18, 22, 23 is recorded and stored in the memory 17 on each journey, both up and down Thus, the system can advantageously adapt to changes and ensure continued operation of the industrial door 1. The force curves are stored in the nonvolatile memory 17, so that the safety conditions can be met even if there is a loss of power, which the TÜV regulations require. the automatic control algorithm can not work anymore

corrective intervene, but the gate can still be closed or the problem can be solved, including the Totmannschaltung offered as proposed by the invention. While the industrial door 1 is stopped when driving upwards, which represents a safety catch, the signal light 19 on the box 3 of the door control 4 lights up when reversing to the upper end position after the drive downwards. As a result, the operator sees that the

Force detection has triggered. This can of course also be done by the industrial door 1 by the emergence of a person or a

Reversed the subject. By operating the button 1 1, the industrial door 1 moves automatically down and the indicator or signal light 19 goes out. But there is also the possibility that the industrial door 1 is reversed again in the operation of the key 1 1 and moved back into the upper end position. This means that the force detection has detected a problem that requires that the force curve be re-read. The reading or teaching is done so that the button 1 1 is held on departure, at the same time the signal light 19 at the door control 4 flashes. By the Holding the button 1 1 to the lower end position, the force detection learns in the background a new force curve. If the door reaches the lower end position, then the signal light 19 goes out, so that the industrial door 1 is then able to open and close automatically.

Should be at the next Torabwärtsfahrt but a serious

Problem occur, reverses the industrial door 1 again and remains in the upper end position. The user can then repeat this process again and possibly close only the industrial door 1 and then leave the door system to be maintained by a specialist.

All the above features, including the drawings alone

taken, are considered alone and in combination as essential to the invention.
