Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a yarn supply device that alternately supplies inspection yarns and auxiliary yarns to a yarn inspection machine.

(Prior art and its problems) Generally, when inspecting the physical properties of drawn or drawn false-twisted yarn, for example,
This is carried out by the method described in Japanese Patent Application Laid-open No. 130348 or Japanese Patent Application Laid-Open No. 130388/1983. In the above inspection method, a lead thread (approximately 50 m) is used to set it in the thread inspection machine, a reference thread (approximately 15 m) is used as a standard for measuring physical properties, and multiple test threads (approximately 10 m) and lead yarn (approximately 50 m) are sequentially supplied to an automatic yarn splicing device and connected into a single yarn, and the yarn is sent to a yarn inspection machine for measurement. The yarn inspection machine distinguishes the type of lead yarn, reference yarn, test yarn, etc. based on the joints and lengths of the yarn, and first measures the physical properties of the reference yarn, and then measures the physical properties of each test yarn. Physical properties are measured and compared with standard values, and the results are recorded in the order in which the test yarns were supplied. The spools serving as the test threads are placed on a creel table with protruding pegs in a substantially horizontal state in multiple stages in the vertical direction and in multiple rows in the horizontal direction, and are fed in a predetermined order. , measurement results are also recorded in that order. Therefore, if there is a place where the bobbin body is not placed at a predetermined position, the measurement result of the next test thread is recorded at the recording position of the measurement result of the thread, even though the test thread is not supplied, and the test result is The thread and its measurement results will deviate, making it impossible to obtain accurate measurements. Therefore, if the bobbin body is not placed in the predetermined position, an auxiliary thread (approximately 3 m) of a length different from the test thread is supplied instead of the test thread, and due to the difference in thread length, It is determined that it is an auxiliary thread, and the measurement results are kept consistent with each test thread.

Therefore, if the bobbin body is not placed in a predetermined position, the worker uses a suction device to pull out the thread from a separately prepared bobbin body and supplies it to the automatic splicing device as an auxiliary thread. The operator must perform the operations of suctioning the thread end of the bobbin body into the suction device and supplying it to the automatic thread splicing device, making it impossible to fully automate the process. There was a problem that if the operator overlooked this, the measurement results would be incorrect.

(Objective) The object of the present invention is to perform an operation for detecting whether or not a bobbin body is placed on a predetermined position, and an operation for supplying an auxiliary yarn instead of a test yarn when a bobbin body is not placed on a predetermined position. The goal is to be able to do this automatically.

(Means for Solving the Problems) That is, the present invention includes a yarn feeding section that holds a bobbin body for auxiliary yarn, and a detector that inspects the presence or absence of a bobbin body for inspection mounted at a predetermined position. , a suction device installed in the vicinity of the yarn feeding section, and a suction device installed between the yarn feeding section and the suction device to hold the yarn end sent out from the auxiliary yarn bobbin winder, and as needed. A guide device that delivers the end of the thread to the suction device, and a cutter that is installed near the guide device and cuts the auxiliary thread or the test thread, and there is no thread wound body for testing at a predetermined position. Another object of the present invention is to provide a yarn supply device that supplies an auxiliary yarn to an automatic yarn splicing device instead of a test yarn.

Here, the yarn feeding section is a unit that supplies auxiliary yarn from a spool of thread such as cheese or pirn, and has a holder protruding from an automatic yarn splicing device or a separately placed creel table to place the spool of thread on it. Make it.

In addition, the suction device is a device that suctions the auxiliary yarn sent out from the yarn feeding section and the inspection yarn sent out from the bobbin body mounted on a creel truck, etc., and supplies it to a predetermined position. The movable suction tube has a suction force generator, and a drive device for moving the suction tube. In addition to a cylinder, the drive device can be implemented by a combination of an electric motor and a gear mechanism, or a combination of an electric motor and a screw mechanism. Further, the guiding device is formed of a suction force generator and a guide attached to the entrance and exit of the suction force generator, and is arranged between the above-mentioned yarn feeding section and the suction device. The cutter is a fixed blade, one composed of a fixed blade and a movable blade, or one made of heating wire, etc., and the cutter is moved to the thread cutting position and the standby position by a device similar to the drive device for the movable suction pipe described above. move between.

Pressurized air is supplied to the suction force generator 5 to generate suction force, and the drive device 6 is activated to move the movable suction pipe 3
At the same time, the nozzle 4 is moved to the position of the bobbin. If the bobbin body 40 is not placed at a predetermined position, a signal thereof is sent from the detector 7 to a control device (not shown). Based on the signal, the drive device 6 is activated, and the three movable suction tubes 3 are returned to their original standby positions. The movable suction tube 3 has an auxiliary thread 3 as a missing thread.
In order to supply 0a, the suction force is maintained in the nozzle 4. Next, the compressed air supply piping 1
8 is switched, compressed air is supplied to the suction force generator 14 of the guiding device 12, the compressed air is ejected from the guide 16, and the ejection force of the compressed air causes the thread end 30b hanging down from the guide 16 to be connected to the suction device. The liquid is guided near the nozzle 4 of No. 2 and sucked in. The yarn end 30
When b is suctioned, the supply path of the compressed air supply piping 18 is switched and the supply of compressed air to the suction force generator 14 of the guidance device 12 is stopped. Further, when the auxiliary yarn 30a sucked from the nozzle 4 is sent to a predetermined position, the supply of compressed air to the suction force generator 14 of the suction device 2 is stopped. When a predetermined amount of the auxiliary thread 30a is supplied from the bobbin winder 30, the cylinder 20 is activated, the rod is projected, and the cutter 19 and guide 22
is moved to the cutting position, and the guide 22 and the guide 2
