Definitions

  • the invention is based on a method and a device according to the preambles of claims 1 and 8.
  • controllable screwdrivers have means, in particular torque sensors and / or rotation angle sensors, by means of which the measured values are recorded and fed to a control circuit. Depending on the measured parameters, the screwing process is automatically ended when the specified values are reached.
  • Shut-off screwdrivers are also known which are shut off by a mechanical clutch.
  • Such screwdrivers are used on a large scale in industrial production. Since several screw connections often have to be carried out in many production steps in production, screw connections can be accidentally omitted.
  • the correct screw connections can be monitored by counting the correct screw connections per screw cycle, for example per production cycle or per component, for which the screwing processes must be recorded. Accordingly, a distinction must be made between proper screw connections and an empty screw connection in which the operator actuates the start lever of the screwdriver without inserting a screw. turn.
  • Such an empty screw connection can occur, for example, between two screwing-in processes if the operator tests the functionality of the screwdriver or accidentally actuates the start lever. On the other hand, an empty screw connection can occur if the screwing process is interrupted prematurely.
  • the invention is based on a method for producing a screw connection by means of a shut-off screwdriver, which ends a screwing process of a screw connection when a predetermined torque is reached.
  • shut-off screwdriver data relating to an operation in the shut-off screwdriver be determined and transmitted to an external monitoring unit.
  • Operating data are preferably obtained internally in the shut-off screwdriver and transmitted to the external monitoring unit. This is expediently carried out by radio transmission. However, transmission via a cable is also conceivable. If data is outside a tolerance range, an error message can be output, in particular the shut-off screwdriver can be shut down.
  • a reliable quality control of the shut-off screwdriver can be carried out in particular a production process on an assembly line.
  • the error message is preferably to lock the shut-off screwdriver.
  • Data relating to the work process, in particular with regard to the proper and non-performed screw connections, is preferably determined and blocked if the number of screw connections is outside a tolerance range of the shut-off screwdriver. This has the advantage that the operator cannot continue his work by locking the shut-off screwdriver. The error in the tightening cycle must first be remedied.
  • the data are preferably recorded by means of an evaluation circuit and transmitted to a monitoring unit, in particular an external monitoring unit located at a distance from the shut-off screwdriver. It is preferably recognized and evaluated in the evaluation circuit whether a screw connection has been carried out successfully or not. For example, the evaluation circuit sends a signal "screw connection correct" or "screw connection not OK" to the monitoring unit. The monitoring unit records the data and evaluates it on the basis of predetermined limit values. If the data is outside the tolerance range, a corresponding signal is transmitted to the shut-off screwdriver.
  • further data which appear sensible to a person skilled in the art, in particular operating data of the shut-off screwdriver can be transmitted from the shut-off screwdriver to the monitoring unit, such as whether a screw connection has taken place, whether a screw connection was correct or incorrect, and / or Time and / or a date when a screw connection was carried out and / or a duration of the screw connection process and / or a duration of an overall cycle, For example, a certain number of screw connections per screw cycle, and / or limit values for a current consumption and / or a voltage drop during the screw connection as a measure of the quality of the screw connection and / or information about loosening or tightening a screw, ie about actuating right-hand o- the counterclockwise rotation of the shut-off screwdriver.
  • shut-off screwdriver is expediently registered with the monitoring unit in the form of a transmitted signal.
  • the data By capturing the data in an external monitoring unit, which is coupled, for example, to a computer, the data can be captured and evaluated online.
  • the quality of the screw connections is checked, for example, by comparison with certain limit value criteria, and a correction of the screw connections is necessary if the limit value criteria are not met.
  • the number of screw connections per screw cycle is expediently recorded in the evaluation circuit.
  • the duration of the screw connection is recorded in the evaluation circuit.
  • the current consumption and the voltage drop of the shut-off screwdriver can be recorded in the evaluation circuit when screwed on. This data is particularly preferably not only recorded, but also evaluated as correct or incorrect.
  • the determined and evaluated data of the evaluation circuit are preferably transmitted to the external monitoring unit by means of a transmitter.
  • An advantage of an external monitoring unit is that a plurality of shut-off screwdrivers, in particular battery-operated shut-off screwdrivers, can be monitored with a single monitoring unit, which is advantageous, for example, in a production line.
  • each of the majority of the monitored shut-off screwdrivers can have a corresponding coding for unambiguous identification, which is known to the monitoring unit.
  • the shut-off screwdriver is connected to the monitoring unit via a cable and data between the shut-off screwdriver and the monitoring unit are transmitted via the cable. If necessary, the shut-off screwdriver can also be supplied with power via the cable.
  • Limit values for the data transmitted from the evaluation circuit are preferably stored in the monitoring unit and are compared and evaluated with the transmitted data. If the limit value criteria are not met, the monitoring unit sends a signal to the shut-off screwdriver with which the shut-off screwdriver is locked.
  • a device for carrying out a method in which a shut-off screwdriver is connected to an evaluation circuit, which is coupled to an external monitoring unit via a transmitter.
  • the shut-off screwdriver preferably has a receiver with which the power supply to the shut-off screwdriver is interrupted via a transmitted signal.
  • the monitoring unit preferably has a transmitter / receiver system with which the data transmitted from the evaluation circuit is received and a blocking signal is sent to the shut-off screwdriver.
  • the transmitter / receiver system of the monitoring unit can communicate with a transmitter / receiver system of the shut-off screwdriver.
  • the monitoring unit has an evaluation unit, in which the data transmitted from the evaluation circuit are stored and compared and evaluated with limit values for the transmitted data. If the limit value criteria are not met, the evaluation unit sends a signal to the shut-off screwdriver, which is used to interrupt the power supply in the shut-off screwdriver via a control device.
  • the evaluation unit is preferably a computer that processes the data online.
  • the invention is particularly suitable for battery-operated shut-off screwdrivers, particularly advantageously for industrial cordless screwdrivers.
  • Fig. 1 shows the schematic structure of an embodiment of a device according to the invention.
  • FIG. 1 shows a device in which a shut-off screwdriver 10 is designed as a battery-operated shutoff screwdriver.
  • the shut-off screwdriver 10 has a torque sensor 12 for detecting the torque of the motor 14.
  • the shut-off screwdriver 10 has a control device 16 which switches the motor 14 on or off and causes the motor 14 to run clockwise or counterclockwise.
  • the control device controls the motor 14 in terms of its output and speed.
  • Torque sensor 12 and control device 16 are connected to an evaluation circuit 18 which is only indicated here, in particular the evaluation circuit 18 can be integrated in the shut-off screwdriver 10.
  • the evaluation circuit 18 recognizes and decides whether a screw connection has been carried out correctly or not and delivers a corresponding signal to an external monitoring unit 20. If necessary, the evaluation circuit 18 can recognize and decide whether other operating data of the shut-off screwdriver 10 are correct or not.
  • the torque increases with the screwing progress, such that the moment the screw touches the parts to be connected with its screwing head, the torque increases.
  • the torque increases up to a target torque at which the shut-off screwdriver 10 is to shut off.
  • the current data “screw connection in order” and “screw connection not in order” are recorded and evaluated or evaluated by means of the evaluation circuit 18.
  • shut-off screwdriver 10 works in idle, a certain idle torque that is less than the target torque is assigned to idle.
  • the screw connection is empty, which is counted in the evaluation circuit 18 and is assessed as incorrect. If the target torque is reached, there is a proper screw connection, which is also recorded in the evaluation circuit 18 and is evaluated as a correct screw connection. In addition, the duration of the screw connection as well as the current consumption and the voltage drop during the screw connection are recorded in the evaluation circuit 18.
  • the ascertained or evaluated data are transmitted to an external monitoring unit 20 by means of a transmitter in the evaluation circuit 18.
  • the monitoring unit 20 has an evaluation unit 22 with a transmitter / receiver system, with which the data transmitted from the evaluation circuit 18 are received and, if appropriate, a blocking signal is sent to the shut-off screwdriver 10.
  • the evaluation unit 22 is, for example, a computer that processes the data online.
  • the evaluation unit 22 of the monitoring unit 20 stores the data transmitted from the evaluation circuit 18.
  • the transmitted data are compared and evaluated with limit values which are stored in the evaluation unit 22.
  • the evaluation unit 22 sends a signal to the shut-off screwdriver 10, with which the power supply in the shut-off screwdriver 10 is interrupted via the control device 16.
  • shut-off screwdriver 10 is blocked. If the limit values of current consumption to voltage drop during the screw connection, which represent a measure of the quality of the screw connection, are not reached, the shut-off screwdriver 10 is blocked and the work process is interrupted. The operator can continue the screwing process via the control device 16, can only carry out the tightening cycle successfully if the errors have been eliminated. If the source of the error is not eliminated, the shut-off screwdriver 10 is blocked again via the monitoring unit 20.
  • shut-off screwdriver 10 can be blocked if it is removed from the area of action of the monitoring unit 20 and can be activated if it is brought into the area of action of the monitoring unit 20.
