Description

Technical Field

[0001] This application belongs to the technical field of double-twisting machines, and particularly relates to a steel cord external pay-off broken wire monitoring device. Background Art

[0002] During the processing of wire products such as steel cords, due to the influence of factors such as raw materials, different structures, and manufacturing process control during the twisting process of wire products such as steel cords, different defects exist on the twisting surface of wire products such as steel cords.

[0003] However, during the production process of the steel cord external pay-off double-twisting machine tool, due to the poor twisting of the steel wire, it is easy to cause wire breakage. After the wire breaks, it may get stuck at the horizontal guide rod and will not touch the wire break protection device under the external traction wheel. At this time, if the machine tool does not stop in time, it will cause quality hazards in the produced cord. Summary of the Invention

[0004] In view of the above problems existing in the prior art, this application provides a steel cord external pay-off broken wire monitoring device, which can monitor the wire breakage situation during the pay-off process of cord production and stop the machine in time to improve product quality.

[0005] To achieve the above object, the technical solutions provided by this application are as follows:

[0006] This application provides a steel cord external pay-off broken wire monitoring device, including:

[0007] A pay-off wheel and a pay-off seat, with the steel wire wound around the pay-off wheel, and the pay-off wheel rotates around the pay-off seat for wire pay-off;

[0008] A pay-off wire distributing disc, on which there are wire passing holes, and the steel wire passes through the wire passing holes and then enters the double-twisting machine through a wire pressing die for processing;

[0009] A wire passing pulley, arranged on the pay-off wire distributing disc, for guiding the wire and avoiding the steel wire from contacting the wire passing holes;

[0010] A controller, used to control the machine tool to stop. A detection device for detecting the contact state between the steel wire and the wire passing hole is arranged on the wire passing hole, and the detection device is connected to the controller.

[0018] Compared with the prior art, the present application has at least the following beneficial effects:

[0019] In the present application, by providing a wire-passing pulley, the steel wire can smoothly pass through the wire-passing holes on the wire-releasing and wire-splitting disc under normal circumstances without contacting the hole walls of the wire-passing holes. Once wire breakage occurs due to poor wire twisting, the steel wire will become loose from the tightened state and slide down, contacting the contact sensor. The controller receives the signal transmitted by the sensor and can thus give an alarm and stop the machine in time, improving the production efficiency and product quality of the steel cord.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. The description of at least one exemplary embodiment is actually only illustrative and in no way limits the present application and its application or use.

[0025] Embodiment 1

[0026] As Figure 1As shown in the figure, a steel cord external wire pay-off broken wire monitoring device includes a wire pay-off wheel 1, a wire pay-off base 2, a wire pay-off and distribution disc 3, a wire pressing die 4 and a controller. The steel wire 7 is wound around the wire pay-off wheel 1, and the wire pay-off wheel 1 rotates around the wire pay-off base 2 for wire pay-off. Then the steel wire 7 passes through the wire pay-off and distribution disc 3; there are wire passing holes on the wire pay-off and distribution disc 3, and after the steel wire 7 passes through the wire passing holes, it enters the double-twisting machine 5 through the wire pressing die 4 for processing; there are wire passing pulleys 6 on the wire pay-off and distribution disc 3, and the wire passing pulleys 6 can conduct the wire and at the same time avoid the steel wire 7 contacting the wire passing holes; a controller, in this embodiment, the controller is a PLC controller, which is used to control the machine tool to stop. There is a detection device for detecting the contact state between the steel wire and the wire passing hole on the wire passing hole, and the detection device is connected to the controller.

[0027] The detection device and the controller can be connected by wire or wirelessly, such as Bluetooth, Wi-Fi, etc., as long as the signal transmission between different components can be achieved. In this embodiment, the detection device and the controller are connected by wire.

[0028] The detection device includes a contact sensor. The contact head of the contact sensor usually works when two objects contact and press each other. When the steel wire breaks, the steel wire touches the contact sensor, and the force or vibration at the contact point is detected, and then the contact signal is transmitted to the controller.

[0029] Normally, the steel wire 7 passes through the wire passing hole on the wire pay-off and distribution disc 3 smoothly through the wire passing pulley 6 without contacting the hole wall of the wire passing hole. When a wire break occurs, the steel wire 7 will become loose from the tightened state and slide down, contacting the contact sensor. The controller receives the signal from the sensor and can stop the machine in time, improving the production efficiency and product quality of the steel cord.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that: there is a traction wheel 8 between the wire pay-off wheel 1 and the wire pay-off and distribution disc 3, and horizontal guide rods 9 are provided on both the incoming wire side and the outgoing wire side of the traction wheel 8 to ensure the smooth wire passing of the steel wire 7.

[0032] Due to the quality of the steel wire 7 itself or the phenomenon that the guide wheel, guide rod or wire passing pulley 6 is not installed easily by the operator during the operation of the machine tool, it will also cause quality problems such as the steel wire being hard ground and scratched and getting fuzz. The contact sensor is arranged on the inner peripheral side of the wire passing hole. Thus, when problems such as wire break or fuzz of the steel wire occur, they will all contact the contact sensor on the wire passing hole and the double-twisting machine tool will stop in time.

[0033] Multiple groups of wire pay-off wheels 1 are provided, and the wire pay-off and distribution disc 3 is disc-shaped, and a plurality of wire passing holes and wire passing pulleys 6 are correspondingly arranged thereon.

[0034] It further includes an alarm. The detection device is connected to the alarm. Generally, the alarm reminds people to take response measures in the form of sound and light. In this embodiment, the alarm is an audible and visual alarm, which can give alarms such as sound and flashing warning lights at the same time. Under normal circumstances, the steel wire 7 passes through the wire passing hole on the wire laying and distributing disc 3 smoothly through the wire pulley 6 without contacting the hole wall of the wire passing hole. When there are problems such as broken wires or fraying, the contact sensor will be touched. The contact sensor detects the contact signal, so as to timely control the wire rolling and twisting machine tool to stop. At the same time, the alarm outputs an alarm, which can be timely fed back to the staff for inspection, improving the production efficiency and product quality of the steel cord.

[0035] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0036] The above are only the preferred embodiments of the present application. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present application, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present application.
