Definitions
- the invention relates to a control for an industrial machine with a motor control arranged in or on the sewing machine head and a sewing sequence control accommodated in a special operating part, wherein the operating part and the motor control are connected via a bidirectional interface, and wherein solenoids and digital switching inputs include actuators such as thread wipers and thread cutters and the like are controlled by the controller.
- a control of the generic type is known from DE 40 00 765 C2. According to this publication, both the engine running control and the control of the actuators are accomplished via a serial interface.
- the object of the invention is to design such a control so that the wiring can be carried out in a simple and clear manner in a cost-effective manner in the manufacturer's plant and the control is hardware-independent of the specific sewing machine types.
- the motor control is used to control the run-up and run-down and the speed of the motor, and the actuation of the actuators is carried out separately via a serial bus
- the serial bus being BBOBI (Bit Bit Out Bit In) - Bus
- the bus is designed as a 3-wire bus, comprising a data line and two supply lines. The bus is looped through every node. The respective node taps the three lines.
- the sewing control operates the data line, the transmission protocol advantageously consists of a start bit and eight data bits.
- the sequence control recognizes from this that the respective node circuit arrangement has responded.
- the configuration according to the invention achieves simple and clear wiring in and on the machine while avoiding cable clutter, with expansion options being possible at any time and the wiring already being able to be implemented inexpensively in the manufacturing plant.
- the sequence control is also free of control elements for actuators and the associated power supply unit and is therefore considerably smaller, whereby the power supply unit for the actuators can be accommodated decentrally.
- L The complete control system only has the actually required number of control elements. Since the bus nodes and the actuators form a unit and these are already installed in the manufacturer's sewing machine manufacturer, it is known at the time of assembly whether power electromagnets or solenoid valves for operating the actuators are provided. Depending on this, power supplies of different sizes can be used. Power supplies for solenoid valves are much smaller and therefore cause significantly lower costs.
- the bus distinguishes between a "write” and a “read” state. With “Write” two bits can be output per address. In the "Read” state, the switching level of an on / off switch that can be connected to the node is placed on the data line for a short time instead of the "OK" mentioned above.
- the input switches can be connected to the closest node circuit arrangement, and the assignment can be implemented in software.
- the converter and the motor control as well as the motor are arranged in or on the nafon machine, the control being carried out via a digital signal processor (DSB), for example ADMC328.
- DSP digital signal processor
- the converter and motor control control the acceleration, turning, braking and positioning of the needle completely independently.
- This part of the overall control system is written down in a ROM, for example.
- the sewing program is included in the sequence control. This control is located outside of the sewing machine in or on the control panel.
- the sewing program can be modular and can be created by the user.
- the operating software for the sewing process is in the sequence control and is only added if new modules have to be introduced.
- the bus according to the invention serves such a module. If the user expands the bus, he must also do this in his user program, the times of the Activation or deactivation and the reactions to the switching states of the input signals must be determined.
- each node circuit arrangement comprises a node circuit element (IC), output switching elements, such as switching transistors, relays or the like, setting elements, such as DIP switches, rotary coding switches or the like, as well as connection elements.
- IC node circuit element
- output switching elements such as switching transistors, relays or the like
- setting elements such as DIP switches, rotary coding switches or the like
- the node circuit arrangements are arranged on a printed circuit board accommodated in a housing.
- a particularly compact design is achieved in that the node circuit arrangements are mounted directly on the actuators or are integrated into them.
- the node circuit arrangements are connected to one another in such a way that the output of a node circuit arrangement is connected to the input of a subsequent node circuit arrangement.
- the output of the last node circuit arrangement can be connected to the sequential control system to enable self-diagnosis.
- FIG. 1 is a plan view of a circuit board with the node circuit arrangement for a solenoid with adjustable timing
- FIG. 2 is a plan view of a circuit board of the node circuit arrangement for a solenoid valve
- Fig. 4 is a block diagram of the node switching part (IC) and
- FIG. 5 shows a time diagram to illustrate the timing of a BBOBI bus according to the invention.
- Essential components of a control according to the invention are the node circuit arrangements 1 and 2 shown in FIGS. 1 and 2.
- the node circuit arrangement 1 is arranged on a printed circuit board 3. It comprises a switching input 4, an output 5 for a clocked solenoid and an output 6 for a display in the form of an LED.
- a programmable address circuit 11 is used to address the respective node circuit arrangement 1 or 2.
- the node circuit arrangement 1, 2 have inputs 12 and outputs 13 for looping through the BBOBI bus according to the invention. For this purpose, three-pole plugs are provided, the output 13 of a previous node circuit arrangement 1, 2 being connected to the input 12 of a subsequent node circuit arrangement 1, 2.
- FIG. 3 schematically shows a controller according to the invention, which is constructed using node circuit arrangements 1, 2 shown in FIGS. 1 and 2.
- a sequence control 14 with an associated pedal 15 is arranged separately from a sewing machine 16 in a manner known per se.
- a motor controller 17, a converter 18 and a motor 19 are arranged on the Nälimascbine 16 itself.
- a 24 V DC voltage is fed to the input 12 of the first node circuit arrangement 1 a.
- the output 20 of the sequence control 14 is also present there.
- the output 13 of the first node circuit arrangement la is connected to the input 12 of the second node circuit arrangement 1b, the output 13 of which is connected to the input 12 of the third node circuit arrangement 1c.
- These first three node circuit arrangements la, lb, lc are used for the clocked activation of a solenoid (EL.MAG1, EL.MAG2, EL.MAG3).
- the subsequent fourth, fifth and sixth node circuit arrangements 2a, 2b, 2c are connected to one another in the same way. They are used to control solenoid valves MV1, MV2.
- This circuit element comprises as essential components a data shift register 21 and a data storage register 22 as well as a comparator 23 and three subordinate hold flip-flops 24. Furthermore, an oscillator 25, a data block generator 26, a time-out counter 27, data end Counter 28, a full magnetic control 29 and a magnetic clocking 30 are provided.
- the transmission protocol consists of a start bit, eight data bits and a return bit.
- the eight data bits are divided as follows:
- the sequence controller 14 drives the D-bus as a master controller, with all node circuit arrangements 1, 2 listening to the D-bus.
- the address 11 of the node circuit arrangement 1, 2 on the respective printed circuit board 3 is set on a switch in the form of a 5-bit DP switch.
- each node circuit arrangement 1, 2 has its own address, 31 different addresses accordingly being able to be implemented.
- the sequence controller 14 addresses one of these node circuit arrangements 1, 2, the 5-bit comparator 23 in the node circuit element 7 detects this. Depending on the level R / WB, a write or read operation takes place. The transmission speed is fixed and is set as high as possible. Depending on the priority, the connected switching inputs 4 are addressed more or less often by the sequence controller 14 and their switching status is queried. Outputs 4, 5 are switched as required.
- the states of bits DO and Dl are assigned to outputs Out 1 and Out 2.
- Out 2 is the direct image of DO.
- Out 1 is treated differently depending on the node circuit arrangement 1, 2.
- the hardware 10 for clocking is also accommodated on the printed circuit board 3.
- Rotary coding switches are used to set the timing, one for setting the initial duration of the full activation and one for setting the timing ratio. The switching of the freewheeling current takes place in a manner known per se via the TRIAC 9.
- Out 1 is the direct image of DI.
- the sequential control system 14 After the transmission, the sequential control system 14 also switches to the "listening" state, since the node circuit arrangement 1, 2 addressed takes over control of the D-bus within a subsequent time window and issues an OK corresponding to the low state to the D-bus , The sequence controller 14 recognizes from this that the addressed node circuit arrangement 1, 2 has responded.
- Power transistors 8 for driving solenoids EL.MAG are provided as output switching elements.
- the second output 6 serves e.g. to control an LED.
