2. Description of the Related Art Conventionally, a package formed by an automatic winder has a mixture of defective packages due to various causes. For example, as shown in FIG. 3 , the yarn end Y ₁ falls from the end face of the yarn layer and winds around the paper tube K, or the end face drop package P _{1 in} the yarn layer, unsuitable tension, contact pressure, winding. There are defective packages such as a package P ₂ having an uneven end surface called a chrysanthemum G caused by eccentricity of the tube, or a package P ₃ having a step T in the yarn layer due to tension fluctuation. There is also a defective package due to a mixed number of packages in which different types of threads are mixed in one package.

When inspecting the above-mentioned defective package, a visual inspection by an operator is performed. To prevent a check error, the applicant of the present invention has proposed a package inspection device. In this device, as shown in FIG. 2 , the inspection device uses the surface 3 of the package 31 to be inspected.
A light source 33 for irradiating the light 2 and a light projector 35 such as a lens 34
A lens 36 for receiving the reflected light, a light receiving portion 38 such as an image sensor 37, and an analyzing device 39 for analyzing the received information. The optical signal obtained by the image sensor 37 is converted into an electrical signal, and the noise eliminator 40
And a signal of a magnitude processed by the amplifier 41 via
Further, it is converted into a digital signal via the analog-digital converter 42. Since this signal is a signal suitable for comparison with the set level, it can be input to the normalization circuit 43 and, if necessary, input to the memory 44 and temporarily held. The normalized signal is input to the level comparator 45, and is compared and calculated by the arithmetic unit 46 with a preset level input in advance. As a result of the comparison, an output signal of a defective package or a normal package is output, and a defective package signal is output. If so, for example, turn on the red lamp,
It is output as a signal for driving the transport distribution device to another transport path. It should be noted that the determination as to whether the package is good or bad based on the image sensor output is omitted.

[0004]

In the above-mentioned conventional inspection apparatus, when the package surface is irradiated with light from the light source and the reflected light is received and analyzed, the end surface drop, chrysanthemum winding, or stepping on the package surface is detected. Since the abnormal state is processed by the image processing of the reflected light, the image of the reflected light will be the same as the above-mentioned abnormal state even if dust thread etc. adhere to the package surface, and it will be judged as a defective package. There was a case that it malfunctioned.

Therefore, an object of the present invention is to prevent the malfunction of the package inspection device due to the attachment of thread waste on the surface of the package.

[0006]

In order to solve the above-mentioned drawbacks of the prior art, the present invention analyzes a light projecting portion that illuminates the surface of a package, a light receiving portion that receives light reflected by the surface, and information received. Before the package inspection unit equipped with the analysis device, the package end cleaning device and the package side cleaning device are installed.
The package inspecting device is configured by providing a package cleaning unit provided with the device , thereby preventing the malfunction of the package inspecting device due to the adherence of thread waste on the package surface.

[0007]

Since the present invention is configured as described above, when the lint is attached to the surface of the package, the lint is sucked by the suction mouth, and the lint is attached to the package in the inspection section. Not like.

Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, signals from an image sensor 4 having a light source 2 for irradiating the surface of the yarn layer of the package 1 and a light receiving portion 3 for receiving the light reflected by the surface of the yarn layer are signal processing means (not shown). By inputting in, and comparing with the standard value, the end surface drop on the package surface, chrysanthemum winding or step,
Further, a package quality determination signal indicating whether a mixed number is generated is output. Defective packages are excluded from the normal conveyor 5 system.

On the line of the conveyor 5, a yarn suction device 7 is provided upstream of the package inspection unit 6. The yarn suction device 7 is provided with a moving roller 12 for pressing the tray 8 toward the support rollers 10 and 11 by the cylinder 9 in order to temporarily stop the tray 8 on which the package 1 is inserted upright at a predetermined position. The support roller 11 is rotatable by a motor 13 in both forward and reverse directions, and the tray 8 is provided with these three rollers 10,
In the state where the tray 8 is held by 11, 12, the tray 8 is rotated by the motor 13 in an arbitrary direction.

In the yarn suction device 7, the upper suction mouth 15 is arranged at a portion facing the upper end surface 14 of the package 1 stopped at a predetermined position, and the package end portion is provided.
A side suction mouse 17 is arranged at a portion facing the surface 16 of the package to configure the cleaning device.
By configuring a side cleaning device,
Provide a sweep section. The upper suction mouth 15 is movable vertically with respect to the upper suction duct 18 by a cylinder 20.
Is horizontally movable by a cylinder 22 with respect to the side suction duct 21. The side suction duct 21 is provided with a cutter 23, and by moving the movable blade 26 with the cylinder 25 with respect to the fixed blade 24, the yarn end passing through this portion can be cut.

In the above apparatus, when the tray 8 conveyed on the belt conveyor 5 passes through the position sensor 19, the cylinder 9 is operated by the output signal of the position sensor 19 to move the moving roller 12.
