Description

[Detailed explanation of the idea]

(Industrial field of application) This invention relates to a recording device for the wire coating process.The wire coated by the wire coating equipment is rolled up one after another to a certain length. To provide a device having a printer that accurately calculates and records the wire length from the tip of an already wound electric wire to that position when the electric wire is wound. (Prior art) This type of conventional recording device places a detector for defective parts such as wire end connections, coating bumps, and poor insulation at a location near the winding machine at the rear end of the process, and detects defects at the moment when they are detected. The current winding length of the winder is recorded as the detection position. Only the outer diameter measuring device must be installed immediately after the coating device to control the coating thickness, but since there is a wire storage section (accumulator) between the measuring device and the winder, it is possible that defects in the outer diameter will not be recorded. In many cases, when recording, the winding length at the time of detection is recorded as the detection position. (Problem that the invention aims to solve) Conventionally, the length of the wire wound by the winding machine up to that point was recorded (printed) by sending signals from the various detectors mentioned above.
Therefore, the printed winding length value, which should indicate the location of the defective portion, deviates from the actual location. The distance traveled from the detector to the winder is recorded as short. In the case of detecting a defective outer diameter using the aforementioned outer diameter measuring device, the distance traveled within the wire storage area is also added, and the actual defective point and
The error from the recorded winding length is several tens of meters. In order to reduce the above error, conventionally there has been a restriction in the installation position that various detectors must be installed as close to the winding machine as possible. The wire end connections (in order to continue the coating work, wires of a fixed length are connected in advance to make the wire longer) are intentionally detected in a coated state that is difficult to notice for the above-mentioned reasons. Generally, when a defective part is detected, winding is stopped, the wire is cut, and a new winding is started, but winding machines have high inertia and are difficult to stop suddenly. For this reason, there was an efficiency constraint in that the winding machine had to be constantly wound at a speed that could be stopped without too much delay when the detector immediately before the winding machine sent a signal. (Means for solving the problem) This invention includes a wire supply section, a coating device, a take-off machine, a wire storage section, a cutting machine, a winding machine, and the above-mentioned take-off machine.
In a wire coating equipment having a measuring device attached to a winding machine, a wire end connection detector and a coating defect detector are provided in the wire supply section and the running path between the wire take-off machines, the take-up machine, The above electric wire storage section between the winding machines is
A storage wire length measuring device is provided, and the line lengths from each of the detectors to the entrance of the wire storage section and from the exit to the end of the wire at the winding start position are given, and the detection signal of the detector is given. The present invention is characterized by comprising a printer with a calculation mechanism that calculates and records the detected position as the wire length from the tip of the wire based on the take-up length, winding length, and storage length data from the measuring device and the measuring device. This is a recording device for the wire coating process. (Function) In this device, various detectors that were conventionally installed centrally in front of the winding machine are installed at arbitrary positions between the strand supply section and the take-up machine, and detect the strands and coated wires. Monitor. The printer that receives the detection signal has a calculation function, and has a pre-given line length from the detector to the wire storage entrance and from the exit to the end of the wire at the winding start position, a take-up machine, and a winding machine attached. The detection position of the transmitting detector is calculated and recorded as the wire length from the tip of the wire, based on the take-up length and winding length from the measuring machine, and the storage length data from the storage wire length measuring device. Needless to say, if there is no strand connection or defective coating in the middle of the wire, the winding length indicated by the measuring device attached to the winding machine is recorded as the total length of the wound wire. (Example) The figure is an explanatory view of one embodiment of this invention, in which C is an electric wire, 1 is a wire supply section, and 2 is a coating device, in which case a plastic extruder is used. 3 is a collection machine,
Reference numeral 4 denotes a wire storage section for storing wire when switching winding, 5 a wire cutting machine, 6 a winding machine, and 7 a wire storage section for switching a wire supply section which is not directly related to this invention. be. A measuring device 8 is attached to the take-up machine 3, and a measuring device 9 is attached to the winding machine 6. The above is no different from before. Among the detectors, the outer diameter measuring device 10 is located in the conventional position in order to check the outer diameter of the covered wire coming out of the covering device 2. Acts as a diameter defect detector. The wire connection detector 11, the bump detector 12, and the insulation tester 13 have conventionally been concentrated near the winder 6. The bump detector 12 detects a portion where the coating has become lumpy. The insulation tester 13 is called a spark tester, and emits sparks when a defective insulation part of the coating is detected. Since this wire coating equipment uses a plastic extruder to coat the wires, the coating device 2 cannot be stopped. While the winding machine 6 is stopped after each winding, the opposing movable pulley groups 4a and 4b of the storage section 4 between the winding machine 3 and the winding machine 6 are
Connect electric wire C between them and store them. When the winding machine 6 resumes winding, the winding speed is increased by about 20% from the normal speed (take-up speed), and after the accumulated amount is consumed, the winding speed is returned to the normal speed. The printer 15 of this embodiment is not just a printing machine, but also has the following functions. (A) The winding length of the winding machine 6 is calculated based on the signal from the measuring machine 9. (B) From the moment a defective part is detected until the defective part reaches the winding start position of the winder, the moving length is counted using the signal from the measuring device 9. (C) Measuring device 14 that indicates the position of the pulley 4a of the storage section 4
The electric wire storage length from the entrance to the exit of the storage section 4 is calculated from the signal from the storage section 4. Note that if you try to always calculate the pooled wire length at the moment of detection of a defective part using only the signal from the stored wire length measuring device 14, it will be difficult to obtain high accuracy due to the A/D resolution and linearity of the sensor. , Within a certain range, the amount of movement of the pulley 4a is measured with an error of about 1 mm, and based on that, the storage line length is calculated by taking into account data such as the number of turns of the electric wire and the dimensions of the pulley. Every time the area is passed, the storage line length data is reset. (D) Always add the signal from measuring device 8 and subtract the signal from measuring device 9 to the value of the wire storage length determined in advance as described above to find the current true storage wire length. Calculate it so that it can be used immediately when a defective part is detected. (E) When a signal is received from detectors 11, 12, 13, etc., the fixed line length from each detector to the storage section 4 entrance and from the same exit to the winder is determined by the above true storage line. The travel distance until the defective part reaches the winding start point is calculated by adding the length to the length. When the defective part has traveled that long distance, the printing mechanism is activated to print the amount of winding at that moment, which shows the distance from the tip of the wire to the defective part. The printer 15 always performs the operations (A) and (D) described above, and constantly calculates the winding length and the storage line length. When the signal from the detector 11 is input to the printer 15, the following calculation is performed. {Length of wire from the detector 11 (defective part) to the tip of the wire at the start of winding of the winder 6} = (Length of the wire from the detector 11 to the inlet of the reservoir 4) + (Length of wire from the outlet of the reservoir 4 to the winding (wire length to the tip of the electric wire at the starting position) + (storage wire length) However, if the detector is located downstream of the storage section 4, the storage wire length is not included and becomes simple. The above calculations are performed at the moment the detection signal is input. After this, winding is continued, and when the measuring machine has counted the amount calculated above, the defective part reaches the winding start position and the winding length at that moment is printed. This winding length is equal to the wire length from the tip of the wound wire to the defective part. Printer 1
5 also includes the date and time of occurrence, lot number, size number,
The signal (defect content) name is also printed. It goes without saying that each detector functions similarly. This ensures that no recording is omitted even if several signals occur in a short period of time. The conventional take-up measuring machine 8 was equipped with only a counter for totaling up the total, but in this embodiment, it is possible to count up by lot and by day. is also recorded. In the above embodiment, even if a defective part is detected, it is not immediately printed, but the defective part is run to the winding start position and the winding length is printed there. This uses a conventional winding length printing device, but it is also possible to calculate the position of the defective portion at the moment of detection and print the numerical value immediately. (distance from the tip of the wire to the defective part) = (winding length)
+ (Line length from defective part detector to reservoir inlet) +
It is determined as (Length of wire from the outlet of the reservoir to the end of the wire at the winding start position of the winder) = (Wind length) + (Storage wire length) + (Constant line length). In addition, if the accumulated wire length measuring device does not measure every moment, but instead indicates the accumulated wire length at the start of winding one turn of wire, the above equation (winding length) can be converted to (take-up length). Just change it. Detector at the start of winding,
The taking-off machine 3 then adds the taken-off length to the line length between the ends of the wire. Next, we will show examples of prints made by the printer based on this invention.

Although one embodiment has been described above, it is natural that this invention can be modified and applied as appropriate depending on the implementation conditions and the well-known technology of the person in charge.For example, all detectors may be installed in front of the collecting machine. First, place a part of the wire near the winder as before, use a model other than the one shown in the drawing for the electric wire storage section, install a separate printer and calculation mechanism, or install a measuring device attached to the winder and take-off machine. You are free to set up a vehicle on a road a little far away. (Effect of the invention) This invention corrects the conventional wisdom that it is unavoidable that the record at the time of finding a defective part in the wire coating deviates from the actual position of the defective part.
We demonstrated that it is possible to reduce the error to about 10 cm. This invention frees up the arrangement of detectors, which conventionally had to be gathered near the winder, so that the space around the winder can be used effectively for rewinding operations and other purposes. Along with this, a wire storage section intervened between the detector and the winding machine, causing difficulties in that the line length changed from moment to moment.
Make good use of the measuring device of the winding machine to maintain a constant line length +
The detection position can be accurately obtained with a simple calculation of storage wire length + winding (or take-up) length. In addition, this idea allows the detector to be installed away from the winding machine, so even if the wire take-up and winding speeds up, there is no problem with stopping mid-way, increasing productivity.
