れないと云う欠点を有している。Ostley Patent No. 190,780 discloses that three separate contact devices are used to avoid unauthorized stoppages of the embroidery machine due to thread loosening occurring during each work cycle, and on the other hand to prevent the embroidery thread from being stopped over a number of work cycles. It has been proposed to allow the unique functions of existing machines to be achieved slowly. This device described above has the disadvantage that it only detects and evaluates yarn breaks or abnormally low tensions.
糸基本張力の監視と制御並びに最後には糸切れを招く異
常な過張力の検出は行われない。There is no monitoring and control of the thread base tension and no detection of abnormal overtension, which could ultimately lead to thread breakage.

特別な装置で行わなければならない。In addition to thread monitoring devices based on electromechanical operating systems for embroidery machines, electrical monitoring devices for textile machines are also known. A description of such a kVc arrangement for monitoring yarn groups is given in DD-WP No. 95901. In this case, the signal for shutting down the machine is generated by the blowing of the thread or, for example, in the case of a handle thread group in a Russell machine, by the contact of a metal stirrup-like member or a tension spring on the contact rail. This also makes it impossible to control the thread basic tension. This control must be done with special equipment.

ことに寄与することである。The purpose of the present invention is to reduce the cost of maintaining a constant thread pull-out force and monitoring the thread in an embroidery machine, and to recognize thread breakage and abnormal thread tension at an appropriate time. The goal is to contribute to reducing costs and achieving high quality embroidered products.

張力が発生した際のイニシアタとして働く。This tensioning device for the individual threads can produce various connections between a number of transmitters and receivers depending on the tension of the individual threads and thus depending on the deviation of the thread tensioning device from the rest state. act. These transmitters and receivers are arranged in such a way that the connections are coaxial with each other and the actuating element runs between the connections when the thread tensioning device is deflected. In this case, a number of individual threads are associated with the transmitter-receiver connection, together with thread tensioning devices and actuating elements. The first of these connections serves as an element in the control circuit to maintain a preselected thread tension during normal operation, while the second serves as a component in the event of individual thread breakage or extremely low tension. and the third bond acts as an initiator when extreme overtension of the thread occurs.

出されるように選択されている。The yarn feed roll is driven in a manner known per se by a stepping motor, the field coil of which is not energized during the entire working cycle of the embroidery machine. The time of excitation Fi is given by a periodic plate rotating with the machine spindle, which acts on the synchronization, the coupling between the transmitter and the synchronization receiver. The direction of rotation of the stepping motor is selected such that when the field coil is energized, the yarn is pulled out of the working position via the yarn feed roll.

が相応する位置に存在しているにも拘らず始動しない。In normal operation, the stepper motor is rotated, and together with this stepper motor, the yarn feed roll is rotated to deflect the yarn tensioning device to which the most strongly tensioned yarn of the group of yarns to be strained belongs; This occurs until the actuating member fixed to this thread tensioning device breaks the connection between transmitter and receiver for normal operation. At the same point in time, the field coil of the stepper motor is no longer energized and the motor and the yarn feed roll connected thereto are held in the locked position. This point is variable during the course of the work cycle and depends on various factors such as transmitter and receiver adjustments, mesh size and direction, thread material and spring constant of the thread tensioner. There is. In the extreme case, this point coincides with the point of excitation of the field coil of the stepping motor. This occurs when the thread is already relatively tensioned in the starting state. In this case, the stepping motor does not start, even though the synchronizer plate is in the corresponding position.

な場合糸を作業方向でたるませることが可能となる。In the other extreme case, the thread is present at the beginning of the movement of the stepper motor and the thread is not engaged by the thread tensioner during the course of the working cycle allowed to the thread tensioner. is not brought into a position where the actuating element could interrupt the transmitter-receiver coupling line. that time,
The stepping motor is rendered current-free via a correspondingly designed synchronizer plate. This event occurs at the same time in each work cycle, whether or not the stepper motor was previously blocked. The de-energizing of the stepping motor now makes it possible in the next phase of the working cycle to idle the yarn feed roll and the stepping motor and, if necessary, to slacken the yarn in the working direction.

。If an individual thread breaks or becomes too loose for the embroidery operation - this is caused, for example, by a number of previous erroneous stitches, the thread tensioner jit belonging to this thread will be removed from the thread drawer. In this case, it is not diverted together with other thread tensioning devices, but rather remains in its untensioned state.

。The operating element remains within the range of transmitter-receiver coupling for normal operation during the entire working cycle. As a result, the step motor does not start despite the synchronous plate method. In the course of the next working cycle, the actuating element of the thread tensioning device acts as a link between transmitter and receiver for overtensioning.
したがって機械は遮断される。The machine is therefore shut off.

の９転と共に刺しゅう位憧方向でたるまされる。Corresponding to the tension present in the thread 1, the actuating element 8
A moderate working phase of the thread tensioning device 7 occurs. This means that the different effects induced by the different working positions of the thread tensioning device M7, which can be derived from its rest position by a tension-induced deflection of the thread tensioning device 7, are in each case only in one working phase of the working cycle. That is, the synchronization plate 19 occurs in the working phase, breaking the coupling between the synchronization transmitter 20 and the synchronization receiver 21. Control unit 2 only within this area
A step motor 4 is driven via the motor 2. This stepping motor itself has a movement transmitted via a torque amplifier 3 to the thread supply roll 2, so that it pulls the thread out of the embroidery position and in the process deflects the thread tensioning device 7 with its actuating element 8. In the remaining working phases of the working cycle, the synchronous transmitter 20-synchronous receiver 21 connection is interrupted. Accordingly, the step motor 4 is in a no-current state, and the yarn 1 is transferred to the yarn feeding roll 2.
With the 9th roll, the embroidery position is sagged in the direction of the embroidery position.

より機械主軸１８が停止される。In normal operation, according to the method of the synchronizing plate 19, the stepper motor controlled by the control unit 22 is fixed to the thread tensioning device 7 from the embroidery position via the four-branch torque amplifier 6 and the thread feed roll 2. The activated actuating element 8 is withdrawn until it breaks the connection between the transmitter 9 in normal operation and the receiver 10 in normal operation. Normal operation - via the switching amplifier 15 and the control unit 22 at this point the stepper motor 4 is blocked since the excitation of its field coil is no longer proceeding. In this state, as the work cycle continues, the synchronization plate 19 cuts off the connection between the synchronization transmitter 20 and the synchronization receiver 21, and the rear stem motor 4 becomes completely non-current), and the yarn feeding roll 2 The thread 1 is held in place until it can be slackened if necessary. If the thread 1 becomes abnormally loose or breaks, the thread tensioner 7 and the actuating member 8 will not be biased during the embroidery process. The actuating member 8 breaks the connection between the low-tension transmitter 11 and the low-tension receiver 12 during the entire working cycle. The signal generated by this K is amplified by a low-tension switching amplifier 16 and transmitted to a tamper-retardant coulter and disconnection device 23, which actuates a contactor 24 according to a preadjustable number of such signals. , whereby the machine main shaft 18 is stopped.

よらずに１作動可能である。In the event of an abnormal overtension in the thread 1, the thread tensioning device 7 is significantly biased and the actuating element 8 breaks the connection between the overtension transmitter 13 and the overtension receiver 14. The signal generated in this way is amplified by an overtension-switching amplifier 17, which causes the contactor 24 to act immediately, i.e.
One operation is possible without a pre-adjustable number of working cycles with extreme overtension.
