JPH04159976A - Method for supplying plural linear bodies - Google Patents

Abstract

PURPOSE:To detect feed completion by arranging the cross sections of linear bodies nearly in a straight line on a feed passage for linear body, and disposing projector and receiver type photoelectric sensors on both sides of the straightly arranged part to detect the presence of a linear body. CONSTITUTION:Guides 4, 5 for arranging the cross section of each linear body 1a-1n straight are provided in the feed passage of the linear body 1a-1n, and projector and receiver type photo-electric sensors 2a, 2b are provided between the guides 4, 5. Thus, if even one of the linear bodies 1a-1n is present between the guides 4, 5, it can be detected by the photoelectric sensors 2a, 2b, and the linear body feed completion can be detected.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a method for supplying multiple striatum.

[Prior Art] (1) A photoelectric sensor may be prepared for each striatal body, and it may be confirmed that all the photoelectric sensors are not detecting the striatal body.

(2) Detect each striatal body relatively close to each other using a guide or the like using a wide-spot photoelectric sensor or a line sensor.

(3) If a dancer is used, check the operation results of the dancer's upper and lower limit switches for all cables.

However, if the sent out filamentous bodies are processed and physically in close contact with each other, it can be confirmed with one detector. (Normally, the machine is often stopped if even one striatum is missing, before detecting that all the striatum is missing.

) [Problems to be Solved by the Invention] In the above-mentioned prior art, when a plurality of sent out striatum bodies are processed without coming into close contact with each other or coming close to each other, a plurality of sensors are required to detect the striatum bodies. Otherwise, a sensor with a wide detection area is required, making it expensive.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a method for supplying a plurality of striatum that makes it possible to easily detect whether or not the delivery of all striatum that are separated from each other has been completed. This is the purpose.

[Means for Solving the Problems] The above purpose is to provide a portion in which the cross sections of each striatal body are aligned in a substantially straight line in the feeding path of the filament body, and to install light emitting/receiving types on both sides of this straight line portion. This is achieved by installing a photoelectric sensor and using this sensor to detect the completion of delivery of the striatum.

r Effect] Since the above means is provided, detection can be performed with one photoelectric sensor, and detection becomes easy.

[Example] The present invention will be described below based on the illustrated example. An embodiment of the invention is shown in FIGS. 1 and 2. FIG. In the method of supplying a plurality of striatum 1a, 1b, 1n, which detects the completion of feeding of a plurality of striatum 1a, 1b, 1n, in this embodiment, each striatum 1a, 1b is placed on the feeding path of each striatum 1a, 1b% in.
, 1n are arranged in a substantially straight line, and light emitting/receiving photoelectric sensors 2as2b are installed on both sides of this straight line. The completion of sending is now detected. By doing this, one photoelectric sensor 2a,
2b, it is possible to obtain a method for supplying a plurality of striatum, which facilitates detection and makes it possible to easily detect whether or not the delivery of all the striatum 1a11b11n that are separated from each other has been completed. can.

That is, the linear bodies 1a, lb, and in supplied from the delivery bobbins 3a, 3b, and 3n advance in two directions with the guide 4.5 restricting the variation in position in the X direction. Align the optical axis with the X direction that is perpendicular to both the X direction and the two directions,
Light emitting/receiving type photoelectric sensors 2a and 2b are installed between the guide 4 and the guide 5.

While the striatum 1 as 1 bs 1 n exists between the guide 4 and the guide 5, the photoelectric sensors 2a and 2b detect any one of the striatum 18% 1b% in, and all the striatum 18% 1b% in are detected. When 1a, lb, and in do not exist between the guides 4 and 5, the photoelectric sensors 2a and 2b are not detected.

As described above, according to this embodiment, only one photoelectric sensor is required and the cost efficiency is high. The guide for the filamentary body does not need to be a special one, and can be used also as a rubber roller for pulling.

Note that the lower guide can be omitted if the variation in the position of each filament in the X direction on the exit side of the guide is small and falls within the detection area of the photoelectric sensor. Further, in order to improve the detection accuracy of the photoelectric sensor, it is preferable to attach a slit elongated in the X direction to the photoelectric sensor.

[Effects of the Invention] As described above, the present invention provides a section in which the cross sections of each striate body are arranged in a substantially straight line in the feeding path of the striated body, and a light emitting/receiving type photoelectric sensor is provided on both sides of this straight line section. A sensor was installed to detect the completion of the delivery of the striatum, making it possible to detect with a single photoelectric sensor, making detection easier, and ensuring that all the delivery of the striatum separated from each other was completed. It is possible to obtain a method for feeding multiple striatum that makes it possible to easily detect whether or not the feeding has been completed.
