Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mesh core separation and feeding device used for separating and aligning mesh cores sent out from a parts feeder at predetermined intervals. In addition, the sorting and sorting of the block-type cores, which are used to sort into good and defective products based on the dimensions of the block-type cores that are separated at predetermined intervals and fed in alignment, is related to equipment. .

Conventional technology For example, in order to manufacture high-performance electronic components by attaching a coil to a threaded core, it is desirable to use a threaded core with high dimensional accuracy. Usually, this is done artificially by sampling about 10 pieces from each lot.

However, since this is insufficient in number to determine the overall quality of the cores, it is preferable to perform the dimensional inspection of even more string-shaped cores.

However, since there are hundreds of lots of the string-shaped cores, and even if you consider it on a monthly basis, each lot is manufactured in the hundreds of thousands of pieces. It is impossible to test.

Problems to be Solved by the Invention Although the dimensional inspection can be handled automatically, for example, a web winding core (Japanese Patent Laid-Open No. 60-65
If the object is relatively large, such as No. 50), automation can be easily achieved. However, since some of the string-type cores used to assemble electronic components are extremely small, measuring several millimeters in size, the dimensions are measured at a mechanical part that physically contacts the core during transport, such as the web winding core mentioned above. Such measures cannot be applied.

To measure this type of small part, it is possible to apply an image processing method that determines dimensional errors by comparing the image of the chain-shaped core captured by a camera with a predetermined dimension. The problem is how to feed the core so that the image processing means can be applied efficiently or how to accurately capture the image of the threaded core.

As a solution to this problem, the threaded cores sent out from the parts feeder are aligned with a shooter and transferred onto the table surface of a drive table such as a turntable, and an image processing means is installed near the drive table to It is conceivable to measure the dimensions of the mold core. However, in this case, simply transferring the chain-shaped cores directly from the shooter will cause the chain-shaped cores to fall over, be misaligned, or have uneven spacing, making it impossible to perform accurate and reliable dimensional measurements.

As a means to separate and supply the threaded cores from the shooter onto the table surface of the drive table, a shutter type as shown in Fig. 11 can be considered, but this shutter type can separate and supply approximately 5 cores per second. In this case, the two shutters S, S2 must be operated alternately at extremely high speeds, resulting in a lack of stability. In addition, a pinch type rubber roller as shown in Fig. 12 can be considered, but in that case, the entry of the threaded core on the inlet side of the rubber roller 1"l+'2 tends to be uneven, so It is difficult to feed separately.Instead of this pinch type of rubber rollers, a push-feed type using horizontally installed rubber rollers as shown in Fig. 13 can be considered, but in this push-feed type, the rubber roller Similar to the above-mentioned pinch type, it is undesirable because it tends to cause variation in the approach and the grip type core is likely to fall over.Also, as shown in Fig. 14, an arc-shaped baffle plate P is installed at the end of the chute, It is also possible to separate the threaded cores that move along the baffle plate P at predetermined intervals based on the curvature of the baffle plate P. However, in this case, the feed-out condition from the parts feeder directly affects the feed-out interval. cannot be determined, and variations tend to occur when the string-type core is separated.

In the field of art, the present invention provides a separating and feeding device for Tsume-type cores, which can align and transfer Tsume-type cores at predetermined intervals, with flanges positioned vertically and sequentially pushed and fed in series by a shooter. The purpose is to

Another purpose is to identify good or good products based on the dimensions of the Tsume-shaped cores sent out from the above-mentioned shooter.
We provide a device for sorting and sorting the threaded cores to efficiently sort out defective products and the like.

Means for Solving the Problems In the device for separating and feeding the pinch-type cores according to the present invention, the pinch-type cores are placed at the end of the chute which sequentially presses and feeds the pinch-type cores in series by positioning the flanges vertically. A plurality of semicircular notches corresponding to approximately half the diameter of the flange are continuously provided on the circumferential surface, and a pair of rotating rollers are disposed facing each other with the protruding ends of the notches being positioned so that they can be relative to each other. It is constructed by equipping a moving table immediately below the opposing position to transfer at predetermined intervals the pinch-shaped cores that are fed out by holding the upper flange between the notches of the rotary rollers. The separation/feeding device can be constructed using a chute equipped with a guide rail into which the winding shaft of the threaded core is inserted and the upper flange is slidably locked. It can be constructed by including a disk that presses and supports the lower flange of the hazel-shaped core on the circumferential side.

This sorting and sorting of the Tsume-type cores is carried out by placing the collars of the Tsume-type cores at the end of a chute that feeds the Tsume-type cores in series with the upper and lower flanges positioned one after the other. A pair of rotary rollers is provided by providing a plurality of continuous circular notches on the circumferential surface and positioning the protruding ends of the notches so that they can be relative to each other. Equipped with a turntable that transfers the Tsume-shaped cores that are fed out by holding the upper flange at predetermined intervals, the dimensions of each Tsume-shaped core can be measured individually by imaging the Tsume-shaped cores placed on the table surface of the turntable. An image processing mechanism that performs discrimination, and a sorting mechanism that drops each of the thread-type cores from the table surface of the turntable into separate receivers based on the discrimination command from the image processing mechanism, and a mechanism that moves the cores along the direction of rotation of the turntable. It is configured by arranging the The image processing device consists of a projector that emits light, a prism that refracts the light from the projector onto the right side of a chain-shaped core placed on the table surface of the turntable, and a prism that transmits the light through the prism. It is possible to use a device equipped with a camera that images the threaded mold core using light irradiated onto the mold core. Also,
The sorting mechanism can be equipped with multiple units that drop into separate receivers according to the discrimination command for each part of the 2-roll shaft part of the Tsuzumi-type core and the flange part, and the sorting mechanism uses image processing. It is possible to use a device equipped with a solenoid that operates in response to a discrimination command from the mechanism and a knob-shaped core button that is operated by the solenoid.

Function: In this mesh-type core separation and feeding device, the collar of the mesh-type core, which has a pair of rotating rollers arranged opposite to each other at the terminal end of the chute, is provided in series on the circumferential side. By holding the upper flange on the inlet side of the rotary roller in each notch, the threaded cores that are sequentially sent out from the chute are taken in, and as the protruding ends of the notches face each other, The upper flange of the mold core is held in the notch, and as each notch rotates in the direction of separation on the exit side of the rotary roller, the upper flange is released from the notch to create a tsuzu mold. Since the cores are transferred one after another onto the table surface of the 8-motion table, the threaded cores are reliably taken in between the notches of the rotary roller and placed on the 8-motion table at precisely the predetermined intervals depending on the rotation speed. It is possible to transfer the cores one after another onto the table surface, and when transferring the cores onto the movable table, it is possible to reliably prevent the interlocking core from falling over or shifting its position. If this separating/feeding device is equipped with a chute equipped with a guide rail into which the winding shaft of the threaded core is inserted and the upper flange is locked so that it can be slid and fed, the feeder will be forced to feed along the guide rail. The mesh core can be guided and fed so that the upper flange of the mesh core is reliably caught by the notch of the rotary roller. In addition, if a disk is provided on the same axis of each rotary roller that presses and supports the lower flange of the chain-shaped core on the circumferential side, the upper flange of the chain-shaped core can be held on the inlet side of the rotary roller and exit. It becomes possible to stably support the Tsuzumi-type core until it is released from the side.

For sorting and sorting of the Tsuzumi type cores, the equipment is equipped with a turntable as a B-movement table that transfers the Tsuzumi type cores from the above-mentioned separation and supply device, and the neighboring Tsuzumi type cores are sorted along the rotating direction of the turntable. A lattice-type core is equipped with an image processing mechanism that individually determines the dimensions by imaging, and a sorting mechanism that drops each tsume-type core into a separate receiving tube based on a discrimination command from the image processing mechanism. While moving over a short distance, it becomes possible to obtain dimensional information about the sling-shaped cores and to select the sling-shaped cores based on this dimensional information. The image processing device is equipped with a prism to irradiate the light from the projector onto the right side of the string-type core, so it can accurately irradiate the right side of the string-type core and obtain a predetermined refractive index. Not only is it easy to install, but the image captured by the camera can be clearly depicted because it does not cause deterioration of the film compared to when using a mirror. In addition, the classification of the Tsuzumi-type core is as follows: The total length of the Mechanism Hasumi-type core is 1.
If multiple units are installed that drop each part of the winding shaft and flange into separate receivers according to the discrimination command, it will be possible to sort out defective products even when sorting out good or bad solid cores based on dimensions, for example. It is possible to sort out each part with dimensional errors. The sorting mechanism is an extremely simple one-piece mechanism, provided that it is equipped with a solenoid that operates in response to a discrimination command from the image processing mechanism, and a button shear with a chain-shaped core that is operated by this solenoid. It can be configured to drop into the core 2 receiver.

An example will be described below with reference to FIGS. 1 to 10.

The embodiment shown in FIG. 1 shows a device for sorting and sorting string-shaped cores, and the sorting and sorting is carried out by feeding the string-shaped cores from a hopper 1 into a parts ball 2, and at the same time using vibrations of the parts ball 2. A core supply section is equipped with a linear feeder 3 from inside to feed out the spring-shaped cores in series with the flanges positioned above and below. A chute 4 is disposed extending linearly from the linear feeder 3 of the core supply section to feed the pinched cores in series in a sequential manner. The shooter 4 has a shooter base frame 4a as shown in FIG. 2a.
The guide rails 4b and 4c are connected to the chute base frame 4a, and the guide rails 4b and 4c slide and feed the threaded core C by fitting the winding shaft c1 and positioning the collar e2+03 vertically to lock the upper collar c2. It can be configured to be laid on top of the As already shown in Fig. 2, this chute 4 can be connected to the feeder from the linear feeder 3 by overhanging the bottom plate 3a of the linear feeder 3 and the guide rail 4b (4c) on the transfer side to control the flow of the Tsutsumi-type core C. You can do 8 lines smoothly,
In addition, by arranging the entire assembly diagonally with a slight downward slope from the linear feeder 3, it is possible to forcefully feed each of the clutch-type cores C so as to constantly press them against rotating rollers, which will be described later.

Ru.

At the end of the chute 4, as shown in FIG. 3, a pair of rotary rollers 5 and 6 are disposed to face each other, thereby providing a chain-type core separation and feeding device. The rotating rollers 5 and 6 of this separation and supply device have semicircular notches 5a, 5b, 5c, .
It has a plurality of consecutive 6cm b on the circumferential side, and its notches 5a, 5b, 5c..., 1
It is attached so that the upper flange part c2 of the Tsuzumi-type core C can be held between the protruding ends of 6a, 6b, and 6cm facing each other. With respect to each rotating roller 5.6, the terminal end side of the chute 4 is slightly beyond the tangent to each roller shaft 5d, 6d, and the guide rails 4b, 4c are located directly below the lower surface of the roller. It is arranged like this.

Further, the notches 5a, 5b, 5c...6a, 6b, 6c of the rotating rollers 5, 6 are provided directly below the opposing position of the rotating rollers 5, 6.
An 8-movement table 7 is disposed for transferring the threaded core between which the upper flange c2 is held and sent out. The movable table 7 can be equipped with a turntable as shown in FIG. It is preferable to install it at a height position where the lower flange C3 of C contacts.

good.

A guide rail 4b is used in the mesh-type core separation and supply device that includes the rotary roller 5.6.

4c locks the upper flange part c2 and sequentially presses and feeds each of the claw-shaped cores C in series to the terminal end of the chute 4.
As shown in the figure, the notch 5 on the artificial side where the protrusions are spaced apart
a, upper flange c of the Tsutsumi-shaped core C located at the beginning in 6a
2 fits in. The notches 5a and 6a are the rotating rollers 5.6
When the protruding ends are positioned relative to each other according to the rotation of 5 6 , each notch 5a, 5
b, 5cm 6a, 6b, 6c... are continuously formed on the circumferential side in a semicircular shape corresponding to approximately half the collar diameter of the Tsutsumi-type core C, as shown by the notches 5b and 6b. By holding the upper flange portion C2 between the notches, one of the sling-shaped cores C is taken in from the shooter 4. As the rotation of the rotating rollers 5 and 6 progresses, the threaded core C that is taken in between the notches of the rotating rollers 5 and 6 opens into the notches 5c and 6.
As shown in 6c, the interlocking core C is connected to the rotating roller 5.
, 6 so that it is released from between the notches and transferred onto the table surface of the turntable 7 which rotates in synchronism with the rotation rollers 5 and 6.

By repeating this operation, the threaded core C can be successively transferred onto the table surface of the turntable 7 by the rotating roller 5.6, so the notches 5a, 5b, 5 of the rotating roller 5.6
c..., 6a, 6b, 6cm, which grips the upper flange c2, are placed on the turntable at a predetermined interval according to the rotational speed of the rotary rollers 5, 6 without causing any fall or misalignment. 7 on the table surface.

In addition to its rotating roller 5.6, each roller shaft 5d, 6d
If a disk 8.9 that presses and supports the lower flange C3 of the threaded core C on the circumferential side is installed on the same axis at the lower side of each rotary roller 5, 6, the rotary roller 5.6 It is possible to stably take in the Tsuzumi-shaped core C and transfer it onto the table surface of the turntable 7. Furthermore, as shown in FIG. 5, the rotating rollers 5.6 are integrally equipped with gear portions 10.11 that mesh with each other, and each of the gear portions 10.11 is integrally mounted with each rotating roller 5.6.
By using one side of the roller shafts 5d and 6d that support the rollers 11 as drive shafts, the rotating rollers 5.6 can be mounted rotatably in synchronization. Each roller shaft 5d, 6
d is supported by a shaft on a bracket stand 12, 13, and rotary rollers 5, 6 can be equipped to rotate at the end of the chute 4 and above the turntable 7. In addition, one side 13 of the bracket base 12 and 13 is inserted and supported by the slide shaft 14, and a compression spring 15 keyed on the axis of the slide shaft 14 presses the bracket base 13 on one side against the bracket base 12 on the other side. It is preferable to equip the rotary roller 6 so as to be capable of separating and retracting so as to allow the rotary roller 6 to escape as the upper flange of the shoe-like core is sandwiched between the protruding ends of the rotary rollers 5 and 6 by supporting it. With this separation and supply device, the wrapped core C is placed on the table surface of the turntable 7.
When reprinting ..., for example, a device can be configured to sort and sort the string cores into good and defective ones according to the dimensional accuracy of the string cores. As shown in FIG.
An image processing mechanism 16 that individually determines the dimensions of... and a discrimination command from this image processing mechanism 16 separates each of the string-shaped cores C... into good and defective products and separately separates them from the plate surface of the turntable 7. Mechanisms 17.18a to 1 are used to sort the items into the receiving case.
8e are arranged in the vicinity of the turntable 7 along the direction of rotation. As shown in FIG. 6, the image processing mechanism 16 includes a detector 161, such as a fiber sensor, which individually detects the 8 moving spring-shaped cores C placed on the plate surface of the turntable 7; A projector 162 that emits light to irradiate C...; prisms 163 and 164 that refract and irradiate the light from the projector 162 onto the right side of the wrap-shaped core C; It can be constructed by including the above-mentioned camera 160 that images the wrapped core C with the irradiated light.

This image processing mechanism 16 is equipped with prisms 163 and 164 to accurately refract the light emitted from the projector 162, thereby enabling parallel illumination to the true side surface of the tsuzumi-shaped core C, making it possible to clearly depict the image captured by the camera 160. Moreover, it is preferable in terms of durability in use and ease of assembly because it does not require peeling of the mirror film like a mirror or requires time and effort to position and install it at a predetermined angle of refraction. In the image processing mechanism 16, when the detector 161 detects the presence of the Tsuzuru-shaped core C... which is placed on the table surface of the turntable 7 and moves 8 times at predetermined intervals, it is detected as shown in FIG. 99 Transfer the core presence signal from the device 161 to the control box 16
This control box 165 sends an image capture signal to the image processing unit 166, and the light projector 162 and camera 160 operate based on the capture command to capture an image of the stick-type core C. This imaging is manually inputted to the image processing unit 166 as data for measuring the dimensions of the Tsutsumi-shaped core C, which determines whether the Tsutsumi-shaped core C is a good product or a defective product based on the dimensional accuracy, and controls the determination command. With feedback to box 165, the sorting mechanism operates one of the mechanisms 17.18a-18e individually based on whether the item is good or bad. In this sorting, when the mechanisms 17.18a to 18e are in operation, the amount of movement of the block type core C by the turntable 7 from the drive motor 7a of the turntable 7 is measured by the rotary encoder 7b.
Each sorter can control the operation of mechanisms 17.18a-18e by transmitting shift timing to control box 165 based on the measurements. As shown in FIG. 80, this determination of quality can be made based on the dimensions of the winding shaft C1 and the flange C2+03 of the threaded core C. Shaft part c and collar part C

As shown in Figure 9a-□d, this processing procedure recognizes the X and Y coordinates of point a from the black and white boundary of the image, and moves 8 n dots in the +X direction from the X coordinate of point a. The coordinates of points b and c are calculated on line x 1 using this point as the starting point. Furthermore, at each line x2 + x3 + X4 that moves 8 in the +X direction from line x, point d % i

Dimensions can be determined based on these coordinates a to 0, and for example, the total length of the chain-shaped core C can be determined based on point a and point n. Depending on the measurement, not only good products and defective products, but also defective products are sorted based on the dimensions of the diameter and width of the shaft, the thickness of the flange, and the outside diameter.
By operating 8a to 18e separately, defective products can be sorted out. This sorting +-1 device 17.18a
