Definitions
- the invention relates to a device for securing a driven movement element against unwanted collisions according to the preamble of claim 1.
- Light barrier arrangement has at least two, preferably at least three or a plurality of staggered in the direction of movement of the gate arranged, preferably parallel light barriers that emit light on one side of the gate and receive or reflect light on the other side of the gate.
- the safety device includes a safety circuit that stops the closing movement of the gate when there is an obstacle in the track of the gate
- the light barrier arrangement is designed in such a way that the surface defined by the light barriers has at least one line in common with the movement surface swept over by the leading edge of the door.
- different activation states can be assigned to the light barriers.
- An activation state is a transition activation state, which is assigned to a control circuit of at least one of the leading gate edge closest, but not yet detecting photocell, such that this at least one light barrier in the subsequent detection of the leading gate edge does not emit the security circuit triggering signal.
- Another activation state is a passive state, the control circuit of each one previously in
- Transition activation state then assigns the light barrier, if this light barrier detects the leading door movement and the allocation of the
- Transition activation state to one of these light barrier in the direction of movement of the door adjacent, previously not yet in the transition activation state located light barrier effected by the control circuit.
- the photoelectric sensors in the passive state do not generate a safety signal that stops the closing movement of the door.
- Object and advantages of the invention is to provide a device of the type described in the introduction for securing a driven movement element against unwanted collisions, which results in an improved safety situation with respect to a movement path of the moving element compared to the prior art.
- This object is solved by the features of claim 1, 7 and 9, respectively.
- the invention relates to a device for securing a driven movement element against unwanted collisions with lying on a predetermined path in the direction of movement of the moving element Obj ect, which comprises a photoelectric barrier arrangement with a plurality of in the direction of movement of the moving element successively arranged light barriers and an electronic unit with which the movement of the movement element as a function of a detected object in a safety mode can be stopped and / or reversed.
- the electronic unit is designed to assign the light barriers different operating states, of which a first operating state is an active state in which the respective object detecting light barrier generates a signal which triggers the safety mode and a second operating state is provided.
- the second operating state is a measuring state in which the respective object detecting light barrier generates a measuring signal which does not trigger the safety mode
- the electronic unit is designed on the basis of a Time difference, which requires the movement element from a first photocell to a lying in the direction of movement of the moving element second light barrier, the time difference on the first and second photocells is determined, and a distance between the first and second photocells a third photocell preferably from the active state to the measurement state to transfer when the moving element is on the way between the second and third photocell and even before the moving element reaches the third light barrier.
- the monitored area can be approximated relatively close to the zoomed motion element. Because the third light barrier can be switched from the active to the measuring state shortly before the arrival of the moving element with appropriate time calculation.
- the electronic unit determines, for example from the time difference from the first to the second light barrier by triggering these light barriers, a time at which the third light barrier would be detected and switches the third light barrier in the measuring state in good time before this event occurs.
- the electronic unit of a light barrier can also assign a passive state, in which neither a measurement signal nor a safety mode is triggered.
- the passive state the j e election photoelectric z. B. be transferred when the moving element in the direction of movement triggers this photocell.
- the corresponding light barrier is then transferred from the measurement state to the passive state.
- the electronic unit assigns the electronic unit two light barriers, which triggers the movement element in a movement in the direction of movement in the light barrier arrangement as the first, the measurement state. If the movement element is located outside the light barrier arrangement before movement, these two light barriers are preferably the first two light barriers of a measuring field of the light barrier arrangement. However, it is also conceivable that the movement element is already in the measuring field of the light barrier arrangement. Then, preferably the two light barriers are assigned the measuring state to which the moving element first encounters a movement in the direction of movement.
- the electronic unit adds a measurement signal of at least one third light barrier to the measurement signals of the first and second light barriers for the calculation of the movement of the movement element.
- a fourth light barrier which lies in the path of movement in front of the moving element, can then be converted into the measuring state.
- the electronic unit is preferably able to determine the speed of the movement element.
- the electronic unit with the addition of at least one third light barrier, is able to determine the acceleration of the moving element.
- the movement of the moving element in the direction of movement can be comparatively predict exactly.
- the switching of operating states of the light barriers can be reduced to a minimum, resulting in a comparatively small gap between the monitored area and the moving element.
- the light barrier arrangement comprises an indicator which indicates which light barrier is in the active state.
- Another essential aspect of the invention resides in a design of the electronics unit such that light barriers which lie in the direction of movement on the path of the movement element are initially held in a passive state and only transferred from the passive state to an active state when the movement element moves in the direction of movement reaches the photocell in a given time.
- the electronics unit with a light barrier arrangement for the control of several, z. B. two in opposite directions Movement elements is designed.
- z. B. the movement of two mutually moving gate elements are hedged.
- two light barriers in measuring mode are preferably each on opposite sides, which are first detected by the respective gate, ie the moving element during a movement in the direction of movement. All other procedures then correspond to what has been described above, with the exception that the safety mode then stops the movement of both gate elements as soon as an object is detected in the movement area.
- the electronic unit is designed so that the light barriers are successively transferred to an active state when moving back a moving element. For this it is necessary that the light barriers are in 'a state of measurement. However, it is also conceivable to bring the light barriers into an active state only when the movement element is outside the monitored area.
- the invention can be used wherever parts of machines or machine arrangements are moved relative to each other. This can be z. B. refer to the monitoring of moving parts on presses or punches.
- FIG. 1 a schematic three-dimensional arrangement of a safety device for monitoring the movement of a gate
- FIG. 2 shows the safety device shown in Figure 1 with gate in a schematic representation
- FIG. 3 shows a section along the section line AA 'in FIG. 2,
- FIG. 4 shows an embodiment corresponding to FIG. 3, but with an alternatively configured gate
- FIGS. 5-1 to 5-V show various representations of a door movement with a detail of a safety device to illustrate the operation of the safety device
- FIG. 6 shows a further embodiment of a safety device in three-dimensional representation in a first position
- FIG. 7 shows that shown in FIG
- 9-1 to 9-III show different representations of gate positions with respect to a schematically illustrated safety device for an embodiment with counter-rotating gate elements in different gate positions.
- Figure 1 shows a gate 1 with a leading edge 4, which is movable in a surface 5.
- a light barrier arrangement 6 of a plurality of staggered in the direction of movement of the door 1 successively arranged light barriers 7-x.
- the x is representative of an integer, z. B. a number 1, 2, 3, etc. and should also make it clear in view of the below that it is an arbitrary number of so designated elements, for. B. photocells (eg 7-1, 7-2, 7-3, ...) can act here.
- the photoelectric sensors can in the visible or invisible light spectrum, z. B. work in the infrared range.
- z. B. work in the infrared range.
- the light barriers 7-x span a surface 11 which lies parallel to the movement surface 5 of the door 1 such that while the door 1 moves downwards along the movement path 2, 3 from the drawn position, the light barriers 7-x are covered successively ,
- Is the door as shown schematically in FIG. 4, mainly from a flexible part Ib, it is not guaranteed that the photocells will be covered or covered when closing the door 1.
- a profile Ib can be formed at the bottom of the door 1 so that it is able to cover the photocells 7-x, which it is currently passing, when closing the door 1.
- the door 1 In the position shown in FIG. 1, the door 1 is located outside the surface 11 spanned by the light barriers 7-x. An obstacle 15 blocks the lowermost three light barriers, which is why the door 1 can not be closed.
- FIG. 2 shows the light barrier arrangement 6 and the door 1 in a frontal view.
- the door 1 is located outside the surface 11 spanned by the light barrier arrangement 6.
- the light barriers 7-x are not interrupted by any obstacle in FIG. 2, which is why the door 1 can be closed.
- a control circuit 13 With a conventional light curtain, the moment the door enters the monitored area, the door would be interpreted as an obstacle, whereupon a control circuit 13 would generate a signal activating a safety circuit 10 and thus stop the door 1.
- the uppermost two light barriers 7-1, 7-2 are in a measuring state.
- a measurement signal is output to the control circuit 13 (FIGS. 5-11 and 5-III) when the light barriers detect an obj ect in the form of the door 1.
- this movement is preferably only interpreted as a door movement when the light barrier signal is emitted within a predetermined time corridor.
- All remaining light barriers 7-x are in the active state, according to the specification of the control circuit 13. Based on the measurement signals of the two located in the measuring state light barriers, the control circuit 13 determines the time in which the light barrier 7-3 would detect the door 1 and switches them in time to the measuring state (see Figure 5-IV). If the door 1 continues to move, then a measurement signal is generated by the light barrier 7-3, which is in the measuring state (see FIG. 5-V), which is used to determine the time at which the light barrier 7-4 of FIG Gate 1 is blocked. This calculation can be based on the last two measurement signals, or on several previous measurement signals. In the latter case, in addition to the speed and the acceleration of the gate can be determined, making a more accurate prediction of the position of the gate 1 is possible. Before the light barrier 7-4 is detected by the gate 1, this is also transferred to the measuring state. This provides another measurement signal when the gate 1 passes the light barrier 7-4.
- a light barrier 7-23, 7-24 is connected in order to be able to monitor the respective area immediately in front of the front edge 4 of the door 1 for obstacles (see FIGS. 7 and 8). If an obstacle 15 z. B. detected by the photocell 7-24 (see Figure 8), a signal activating the safety circuit 10 is generated and the gate stopped and opened.
- each light barrier 7-2x can be provided with an indicator 16-x which indicates whether the light barrier 7-2x is active or not.
- the indicator could z.
- two light-emitting diodes 7-21, 7-22 each shine; 7-22, 7-23; 7-23, 7-24 associated light-emitting diodes 16-1, 16-2; 16-2, 16-3; 16-3, 16-4.
- FIGS. 9-1 to III a gate closing from two sides is shown, as is shown in FIG. B. used in goods lifts.
- This gate consists of two parts Ic, Id, which in opposite directions in z. B. move in the vertical direction. So that neither of the two parts Ic, Id are identified as an obstacle 15, the measuring state must be assigned in good time to the two light barriers 7-lc, 7-2c or 7-ld, 7-2d. This can happen in two ways:
- the light barriers 7-xc determine the speed of the upper half of the door Ic and the measuring state is assigned to the light barriers 7-xc and 7-xd at the same time on the basis of these signals.
- a second possibility is that the light barriers 7-xc determine the speed of the door half Ic and that the measuring state of the light barriers 7-xc is assigned on the basis of this speed.
- the light barriers 7-xd autonomously determine the speed of the door half Id and the measuring state is assigned to the respective light barriers 7-xd on the basis of their measuring signals.
