Description

Technical Field

[0001] This utility model relates to the field of roving frames, specifically to an intelligent roving frame removal status detection device. Background Technology

[0002] The intelligent roving frame removal system relies on the opening and closing of the guide shaft lifting feet and the lower rib plate for removal and insertion operations. After a period of use, some guide shaft lifting feet may fail to descend properly and disengage from the lower rib plate. When removing yarn from the lower rib plate during full yarn unloading or empty tube removal, the removal motor continuously pushes outward, causing inconsistent positioning and asynchronous movement of the lower rib plate. This leads to twisting of the lower rib plate, breakage of the guide shaft support, and bending and deformation of various drive shafts. The escalation of the fault damages the entire removal system, resulting in extremely serious damage to parts and the entire machine. Related technologies involve installing positioning detection devices at the bottom of each lifting foot, but this method is costly. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides an intelligent roving frame removal status detection device. This device uses a remote photoelectric sensor to detect whether the removal position of the lower roving plate is consistent. If an abnormality is detected, the removal motor is stopped promptly via a motor on / off control circuit, thus achieving low-cost removal status detection and fault handling.

[0004] The technical solution of this utility model is: an intelligent roving frame removal status detection device, including a photoelectric transmitter set at the first end of the lower rib plate and a photoelectric receiver set at the second end of the lower rib plate; it also includes a motor on / off control circuit;

[0005] The photoelectric transmitter emits a light signal, and the input of the photoelectric receiver is used to receive the light signal. The output is connected to the control terminal of the motor on / off control circuit. One of the execution terminals of the motor on / off control circuit is connected in series in the power supply circuit of the moving motor, and the other is connected to an abnormal alarm. When the position of the moving rib plate is inconsistent, the input of the photoelectric receiver will not receive a light signal, and its output will output a control signal to the motor on / off control circuit to cut off the power supply of the moving motor, so that the moving motor stops working and the abnormal alarm is activated.

[0008] In an optional implementation, the device further includes a tilt sensor, a comparator, and an OR gate;

[0009] The output of the tilt sensor is connected to the first input of the comparator, the second input of the comparator is connected to the reference voltage, the output of the comparator is connected to the first input of the OR gate, the second input of the OR gate is connected to the output of the photoelectric receiver, and the output of the OR gate is connected to the control terminal of the motor on / off control circuit.

[0010] In one optional implementation, the motor on / off control circuit includes resistor R1, resistor R2, optocoupler U1, transistor Q1, diode D1, relay K1, and NOT gate; optocoupler U1 is a PCI817 model.

[0011] The first end of resistor R1 is connected to the power supply, and the second end is connected to pin 1 of optocoupler U1. The input of the NOT gate is the control terminal of the motor on / off control circuit, and the output of the NOT gate is connected to pin 2 of optocoupler U1. Pin 4 of optocoupler U1 is connected to the power supply, and pin 3 is connected to the base of transistor Q1 via resistor R2. The collector of transistor Q1 is connected to the anode of diode D1, and the cathode of diode D1 is connected to the power supply. The emitter of transistor Q1 is grounded. The coil of relay K1 is connected in parallel with diode D1. The first normally closed contact of relay K1 is connected to the power supply of the moving motor, and the second contact is grounded via the moving motor.

[0012] In one optional implementation, the first terminal of the first normally open contact of relay K1 is connected to the power supply, and the second terminal is grounded via an abnormal alarm.

[0013] In one optional implementation, the first end of the second normally open contact of relay K1 is connected to the power supply, and the second end is connected to the input terminal of the PLC controller.

[0014] In an optional implementation, the motor on / off control circuit further includes resistor R3, resistor R4, capacitor C1, transistor Q2, diode D2, and relay K2;

[0015] Pin 3 of optocoupler U1 is connected to the first terminal of the second normally closed contact of relay K1. The second terminal of the second normally closed contact of relay K1 is connected to the first terminal of resistor R3. The second terminal of resistor R3 is connected to the base of transistor Q2. The first terminal of resistor R4 is connected to the base of transistor Q2, and the second terminal is grounded. Capacitor C1 is connected in parallel with resistor R4. The collector of transistor Q2 is connected to the positive terminal of diode D2, and the negative terminal of diode D2 is connected to the power supply. The emitter of transistor Q2 is grounded. The coil of relay K2 is connected in parallel with diode D2. The first terminal of the normally closed contact of relay K2 is connected to the power supply of the moving motor, and the second terminal is grounded through the moving motor.

[0016] In an optional embodiment, the device further includes a fault alarm, wherein the first terminal of the first normally open contact of the relay K2 is connected to the power supply, and the second terminal is grounded via the fault alarm.

[0017] In one optional implementation, the first end of the second normally open contact of relay K2 is connected to the power supply, and the second end is connected to the input terminal of the PLC controller.

[0018] In one optional implementation, the output of the photoelectric receiver is connected to the input of the PLC controller, and the output of the PLC controller is connected to the control terminal of the motor on / off control circuit. When the position of the lower rib plate is inconsistent, the input of the photoelectric receiver cannot receive the light signal, and its output outputs the first control signal to the PLC controller. The PLC controller outputs the second control signal to the motor on / off control circuit, cuts off the power supply to the moving motor, stops the moving motor from working, and activates the abnormal alarm.

[0019] As can be seen from the above technical solution, this application has the following advantages: Photoelectric transmitters and receivers are set at both ends of the lower rib plate, along with a motor on / off control circuit and an alarm. When the lower rib plate moves out at inconsistent positions, the input of the photoelectric receiver will not receive a light signal. The motor on / off control circuit will then cut off the power supply to the moving motor, stopping it and triggering an alarm. This effectively prevents the lower rib plate from twisting, the guide shaft support from breaking, and the transmission shaft from bending and deforming due to the continuous pushing of the moving motor when the lower rib plate is not in the correct position. This protects the entire moving system, reduces the occurrence of serious component failures and machine breakdowns, lowers equipment maintenance costs and downtime, and ensures the continuity and stability of production. Furthermore, compared to the method of installing a positioning detection device at the bottom of each lifting foot in related technologies, only photoelectric transmitters and receivers need to be set at both ends of the lower rib plate, along with a motor on / off control circuit and an alarm control circuit. This effectively detects and controls the movement of the lower rib plate, greatly reducing the number of detection devices and lowering costs. Attached Figure Description

[0026] To make the purpose, features, and advantages of this application more apparent and understandable, specific embodiments and accompanying drawings will be used to clearly and completely describe the technical solution protected by this application. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] Figure 1 This utility model provides a schematic diagram of the structure of an intelligent roving frame removal status detection device, as shown below. Figure 1 As shown, the device includes a photoelectric transmitter, a photoelectric receiver, and a motor on / off control circuit. The photoelectric transmitter is located at the first end of the lower rib plate, and the photoelectric receiver is located at the second end of the lower rib plate. In some optional embodiments, the photoelectric transmitter is at the head end of the lower rib plate, and the photoelectric receiver is at the tail end of the lower rib plate.

[0029] The photoelectric transmitter emits a light signal, and the input of the photoelectric receiver is used to receive the light signal. The output is connected to the control terminal of the motor on / off control circuit. One of the execution terminals of the motor on / off control circuit is connected in series in the power supply circuit of the moving motor, and the other is connected to an abnormal alarm. When the position of the moving rib plate is inconsistent, the input of the photoelectric receiver will not receive a light signal, and its output will output a control signal to the motor on / off control circuit to cut off the power supply of the moving motor, so that the moving motor stops working and the abnormal alarm is activated.

[0030] Specifically, the execution terminal of the motor on / off control circuit has its first path connected in series with the power supply circuit of the moving motor, and its second path forming a loop with an abnormal alarm. The photoelectric transmitter sends a light signal to the photoelectric receiver. When the moving rib plate is at the same position, the photoelectric receiver receives the light signal and outputs a first control signal to the motor on / off control circuit. The first path of the motor on / off control circuit is normally conducting, while the second path remains open, allowing the moving motor to receive power normally and operate normally. When the moving rib plate is at an inconsistent position, the input terminal of the photoelectric receiver does not receive a light signal, and the output terminal outputs a second control signal to the motor on / off control circuit. The first path of the motor on / off control circuit is disconnected, and the second path is connected, thus cutting off the power supply to the moving motor, stopping the moving motor and activating the abnormal alarm. The first and second control signals can be high or low level signals.

[0031] Figure 2 This is a schematic diagram of a smart roving frame removal status detection device according to a specific embodiment. In this specific embodiment, the detection device includes a motor on / off control circuit, an tilt sensor, a comparator, an AND gate, a photoelectric transmitter disposed at the first end of the lower roving plate, and a photoelectric receiver disposed at the second end of the lower roving plate.

[0032] The photoelectric transmitter emits light signals, the input of the photoelectric receiver is used to receive the light signals, and the output is connected to the second input of an AND gate.

[0033] The tilt sensor is mounted on the lower rib plate. The output of the tilt sensor is connected to the first input of a comparator, the second input of the comparator is connected to a reference voltage, and the output of the comparator is connected to the first input of an AND gate. In some optional embodiments, the tilt sensor is an SCA100T-D01 dual-axis tilt sensor.

[0034] The output of the AND gate is connected to the control terminal of the motor on / off control circuit. One of the execution terminals of the motor on / off control circuit is connected in series in the power supply circuit of the removed motor, and the other terminal forms a loop with an abnormal alarm.

[0035] The photoelectric transmitter continuously emits light signals, which are directed towards the photoelectric receiver located at the second end of the lower rib plate. Simultaneously, a tilt sensor mounted on the lower rib plate monitors its tilt angle in real time and converts the detected angle information into an electrical signal. The photoelectric receiver receives the light signal, converts it into a corresponding electrical signal, and transmits this electrical signal to the second input of the AND gate.

[0036] The electrical signal output by the tilt sensor is transmitted to the first input of a comparator, while a preset reference voltage is connected to the second input of the comparator. The comparator compares these two input signals. After comparing the electrical signal output by the tilt sensor with the reference voltage, if the electrical signal output by the tilt sensor is greater than the reference voltage, it indicates that the tilt angle of the lower rib plate exceeds the preset value, and the comparator outputs a high-level signal; if it is less than the reference voltage, it outputs a low-level signal. The signal output by the comparator is transmitted to the first input of an AND gate.

[0037] An AND gate performs a logical AND operation on the signals at its two input terminals. The AND gate outputs a high-level signal only when both inputs are high; if either input is low, it outputs a low-level signal. The output signal of the AND gate is transmitted to the control terminal of the motor on / off control circuit. When the AND gate outputs a high-level signal, the motor on / off control circuit receives this signal and performs the corresponding action.

[0038] The motor on / off control circuit has two connection points. One connection is connected in series with the power supply circuit of the moving motor. When a high-level signal is received, it will cut off the power supply circuit of the moving motor, causing the moving motor to stop working. The other connection forms a loop with the abnormal alarm. At this time, the abnormal alarm will be triggered, and an alarm signal will be issued to remind the staff that the equipment has malfunctioned.

[0039] This detection device monitors both the position and tilt angle of the lower keel plate, and uses logical operations to control the removal motor and trigger an alarm for any abnormalities. First, a through-beam photoelectric sensor, consisting of a photoelectric transmitter and receiver, monitors the position of the lower keel plate. When the lower keel plate is in a normal position, the photoelectric receiver receives a light signal and outputs a corresponding electrical signal. When the position of the lower keel plate is inconsistent, the photoelectric receiver does not receive a light signal, and its output electrical signal changes, thus determining whether the position of the lower keel plate is abnormal. Second, a tilt sensor monitors the tilt angle of the lower keel plate in real time. The tilt sensor converts the detected angle information into an electrical signal and compares it with a reference voltage. The reference voltage represents the upper limit of the normal tilt angle of the lower keel plate. When the actual tilt angle exceeds this upper limit, the comparator outputs a high-level signal, indicating that the tilt angle of the lower keel plate is abnormal. The AND gate performs a logical AND operation on the results of the position and tilt angle monitoring. The AND gate will only output a high-level signal when both position monitoring and tilt angle monitoring indicate an abnormality in the lower joist plate. This triggers the motor on / off control circuit to cut off the power to the moving motor and activate the abnormal alarm. The dual monitoring and logical AND operation improve the accuracy and reliability of the detection. On the one hand, it avoids equipment malfunctions due to misjudgment caused by a single factor. On the other hand, it only triggers the action when the tilt angle is greater than the preset value, avoiding frequent triggering.

[0040] Figure 3 This is a schematic diagram of a smart roving frame removal status detection device according to a specific embodiment. In this specific embodiment, the detection device includes a motor on / off control circuit, an tilt sensor, a comparator, an OR gate, a photoelectric transmitter disposed at the first end of the lower rib plate, and a photoelectric receiver disposed at the second end of the lower rib plate.

[0041] The photoelectric transmitter emits light signals, the input of the photoelectric receiver is used to receive the light signals, and the output is connected to the second input of an OR gate.

[0042] The tilt sensor is installed on the lower rib plate. The output of the tilt sensor is connected to the first input of the comparator. The second input of the comparator is connected to the reference voltage. The output of the comparator is connected to the first input of the OR gate.

[0043] The output of the OR gate is connected to the control terminal of the motor on / off control circuit. One of the execution terminals of the motor on / off control circuit is connected in series in the power supply circuit of the removed motor, and the other terminal forms a loop with an abnormal alarm.

[0044] A photoelectric transmitter located at the first end of the lower rib plate continuously emits a light signal, which is directed to a photoelectric receiver located at the second end of the lower rib plate. The photoelectric receiver receives the light signal in real time and converts it into an electrical signal. If the lower rib plate is in the correct position, the photoelectric receiver can stably receive the light signal and output the corresponding electrical signal; if the lower rib plate moves out of position inconsistently, the light signal transmission is obstructed, the photoelectric receiver cannot receive the light signal, and its output electrical signal will change accordingly. This electrical signal will be transmitted to the second input of an OR gate.

[0045] An inclination sensor is mounted on the lower rib plate to monitor its tilt angle in real time. The monitored tilt angle is converted into an electrical signal and transmitted to the first input of a comparator. A pre-set reference voltage is connected to the second input of the comparator, representing the voltage value corresponding to the normal tilt angle of the lower rib plate. The comparator compares the electrical signal from the inclination sensor with the reference voltage. If the electrical signal output by the inclination sensor is greater than the reference voltage, it indicates that the tilt angle of the lower rib plate exceeds the normal range, and the comparator outputs a high-level signal; if it is less than the reference voltage, it outputs a low-level signal. The signal output by the comparator is then sent to the first input of an OR gate.

[0046] An OR gate performs a logical OR operation on the signals at its two inputs (from a comparator and a photodetector, respectively). The OR gate outputs a high-level signal as long as either input is high; it outputs a low-level signal only when both inputs are low.

[0047] The output signal of the OR gate is transmitted to the control terminal of the motor on / off control circuit. When the OR gate outputs a high-level signal, the motor on / off control circuit will respond. One path of the actuator of the motor on / off control circuit is connected in series with the power supply circuit of the withdrawing motor. At this time, the circuit will cut off the power supply to the withdrawing motor, causing it to stop working and preventing further damage to the equipment due to the abnormal state of the lower rib plate. The other path of the actuator of the motor on / off control circuit forms a loop with the abnormal alarm. When the OR gate outputs a high-level signal to trigger the motor on / off control circuit, this path will also activate the abnormal alarm, issuing an alarm signal to alert the staff that the equipment has malfunctioned.

[0048] This detection device uses dual monitoring of the position and tilt angle of the lower joist plate, and employs OR gate logic to control the removal motor and abnormal alarm. First, a through-beam photoelectric sensor, consisting of a photoelectric transmitter and receiver, monitors the position of the lower joist plate. Changes in the position of the lower joist plate affect the transmission of the optical signal, thus altering the electrical signal output by the photoelectric receiver. By detecting this change in electrical signal, it can be determined whether the position of the lower joist plate is abnormal. Second, a tilt sensor senses the tilt angle of the lower joist plate and converts it into an electrical signal, which is then compared with a reference voltage. If the actual tilt angle exceeds the normal range, the corresponding electrical signal will be greater than the reference voltage, causing the comparator to output a high level, indicating an abnormal tilt state of the lower joist plate. The OR gate's logic ensures that if either the position monitoring or tilt angle monitoring detects an abnormality, the OR gate will output a high-level signal. This improves the sensitivity of the detection device and provides redundancy, allowing detection even if the through-beam photoelectric sensor fails.

[0049] It should be noted that relevant personnel may select the above options as needed. Figure 2 method or Figure 3 In this way.

[0050] Figure 4 The diagram shows the structure of the motor on / off control circuit in some optional implementations, such as... Figure 4 As shown, the motor on / off control circuit includes resistor R1, resistor R2, optocoupler U1, transistor Q1, diode D1, relay K1, and NOT gate; optocoupler U1 is a PCI817 model.

[0051] The first end of resistor R1 is connected to the power supply, and the second end is connected to pin 1 of optocoupler U1. The input of the NOT gate is the control terminal of the motor on / off control circuit, and the output of the NOT gate is connected to pin 2 of optocoupler U1. Pin 4 of optocoupler U1 is connected to the power supply, and pin 3 is connected to the base of transistor Q1 via resistor R2. The collector of transistor Q1 is connected to the anode of diode D1, and the cathode of diode D1 is connected to the power supply. The emitter of transistor Q1 is grounded. The coil of relay K1 is connected in parallel with diode D1. The first normally closed contact of relay K1 is connected to the power supply of the moving motor, and the second contact is grounded via the moving motor.

[0052] In this configuration, the first normally open contact of relay K1 is connected to the power supply at one end, and the second end is grounded via an alarm. The first normally open contact of relay K1 is connected to the power supply at one end, and the second end is connected to the input terminal of the PLC controller.

[0053] When there is no control signal input, the input of the NOT gate is at a low level, and the output of the NOT gate is at a corresponding high level. The internal LED of the optocoupler U1 is not conducting, and the optocoupler is in a cutoff state. No current flows into the base of transistor Q1, and it is in a cutoff state. There is no current in the coil of relay K1, and its normally closed contact is closed, while its normally open contact is open. At this time, the motor is powered on and running normally, the fault alarm does not work, and the PLC controller does not receive any fault signals.

[0054] When the control terminal (input terminal of the NOT gate) of the motor on / off control circuit receives a valid control signal (high-level signal), the NOT gate performs a logical NOT operation on the input signal and outputs a low-level signal to pin 2 of optocoupler U1. After pin 2 of optocoupler U1 receives the low-level signal, the LED inside optocoupler U1 conducts and emits light, causing the phototransistor inside the optocoupler to also conduct. At this time, a path is formed between pins 3 and 4 of optocoupler U1, and the potential of pin 3 rises. After the potential of pin 3 of optocoupler U1 rises, current is provided to the base of transistor Q1 through resistor R2, causing transistor Q1 to conduct. After transistor Q1 conducts, a current path is formed between its collector and emitter. The current flows from the power supply VCC through the coil of relay K1, the collector and emitter of transistor Q1, to ground, energizing the coil of relay K1. When relay K1 is energized, its first normally closed contact opens, cutting off the power supply to the moving motor and stopping it from working; its first normally open contact closes, making the circuit of the abnormal alarm connected, and the abnormal alarm sounds an alarm; its second normally open contact closes, sending a signal to the input terminal of the PLC controller, notifying the PLC controller that an abnormal situation has occurred in the equipment.

[0055] When the control signal at the control terminal is withdrawn (returns to low level), the NOT gate outputs a high level, the internal LED of optocoupler U1 is turned off, the phototransistor is cut off, there is no current at the base of transistor Q1, transistor Q1 is cut off, the coil of relay K1 is de-energized, and its contacts return to their initial state. Power is restored to the removed motor (if the fault has been resolved), the fault alarm stops, and the input signal to the PLC controller is withdrawn.

[0056] The NOT gate in this circuit performs a logical NOT operation on the input control signal, changing the signal level and acting as a signal converter to provide a suitable level signal for the subsequent conduction and cutoff of the optocoupler. Optocoupler U1 (PCI817) provides electrical isolation. It transmits signals through photoelectric conversion via the internal LED and phototransistor, electrically isolating the control circuit (front-end) from the subsequent drive circuit, enhancing the circuit's anti-interference capability, and protecting the front-end control circuit from interference and influence from the subsequent circuit. When optocoupler U1 is turned on, the output signal current is small and insufficient to directly drive relay K1. A transistor Q1 is connected through resistor R2, utilizing the transistor's current amplification effect to amplify the small current signal output by the optocoupler into a larger current capable of driving the relay K1 coil. When there is a suitable current input to the base of transistor Q1, the collector and emitter conduct, providing operating current for the relay K1 coil. Relay K1 is an electromagnetic switching element. When the coil is energized, it generates a magnetic field that attracts the armature, causing the normally closed contact to open and the normally open contact to close, thus controlling the input signals of the displacement motor, the fault alarm circuit, and the PLC controller. Diode D1 is connected in parallel with the relay K1 coil. When the relay is de-energized, it provides a discharge path for the reverse induced electromotive force generated by the coil, preventing the reverse electromotive force from damaging components such as transistor Q1, thus protecting the circuit.

[0057] Figure 5 The diagram below shows the structure of the motor on / off control circuit in some optional implementations. Figure 4 Based on the structure shown, the circuit also includes resistor R3, resistor R4, capacitor C1, transistor Q2, diode D2, and relay K2.

[0058] Pin 3 of optocoupler U1 is connected to the first terminal of the second normally closed contact of relay K1. The second terminal of the second normally closed contact of relay K1 is connected to the first terminal of resistor R3. The second terminal of resistor R3 is connected to the base of transistor Q2. The first terminal of resistor R4 is connected to the base of transistor Q2, and the second terminal is grounded. Capacitor C1 is connected in parallel with resistor R4. The collector of transistor Q2 is connected to the positive terminal of diode D2, and the negative terminal of diode D2 is connected to the power supply. The emitter of transistor Q2 is grounded. The coil of relay K2 is connected in parallel with diode D2. The normally closed contact of relay K2 is connected in series in the power supply circuit of the moving motor.

[0059] The first normally open contact of relay K2 is connected to the power supply at one end, and the second end is grounded via a fault alarm. The first normally open contact of relay K2 is connected to the power supply at one end, and the second end is connected to the input terminal of the PLC controller.

[0060] Level 1 control and the above Figure 4 The same applies, so I won't repeat it here.

[0061] The second-level control implements relay redundancy control. When the control terminal (input terminal of the NOT gate) of the motor on / off control circuit receives a valid control signal (high-level signal), the potential of pin 3 rises. If relay K1 can conduct normally, its second normally closed contact opens. Before the second normally closed contact of relay K1 opens, the high level of pin 3 is transmitted to capacitor C1, which charges C1. When the second normally closed contact of relay K1 opens, the charging voltage of capacitor C1 is insufficient to turn on transistor Q2, so relay K2 remains inactive, and relay K1 handles the abnormality. If relay K1 malfunctions (such as coil failure or contact sticking), relay K1 will not operate. At this time, the second normally closed contact of relay K1 remains closed. The high level of pin 3 of optocoupler U1 is delayed by the delay circuit composed of resistor R4 and capacitor C1. That is, after capacitor C1 is continuously charged to a certain voltage, transistor Q2 is turned on, which in turn powers relay K2, triggering the de-energization of the motor. At the same time, the fault alarm is triggered, and the fault signal is transmitted to the PLC controller to ensure that the abnormality of the motor can be handled normally even when relay K1 malfunctions.

[0062] In some optional embodiments, the detection device includes a photoelectric transmitter, a photoelectric receiver, a motor on / off control circuit, and a PLC controller. The photoelectric transmitter is located at the first end of the lower rib plate, and the photoelectric receiver is located at the second end of the lower rib plate; specifically, one is at the head end of the lower rib plate, and the other is at the tail end of the lower rib plate.

[0063] The photoelectric transmitter emits a light signal, and the input of the photoelectric receiver receives the light signal. Its output is connected to the input of the PLC controller, and the output of the PLC controller is connected to the control terminal of the motor on / off control circuit. One path of the motor on / off control circuit is connected in series with the power supply circuit of the moving motor, and the other path forms a loop with an alarm. When the moving position of the lower joist plate is inconsistent, the input of the photoelectric receiver does not receive a light signal. Its output sends a first control signal to the PLC controller, which then outputs a second control signal to the motor on / off control circuit, cutting off the power supply to the moving motor, stopping the moving motor, and activating the alarm.
