In order to solve the above-mentioned problems, according to the first aspect of the present invention, the core is mounted on a stocker for stocking the core by a vacuum suction mechanism provided at the tip end. A core suction hand for sucking, a core transport mechanism for freely moving the core suction hand in the X, Y, and Z-axis directions, and a control mechanism for controlling the drive of the vacuum suction mechanism and the core suction hand and the core transport mechanism. A winding core take-out device for a winder in a winder, comprising a vacuum suction mechanism swingably supported through a swing support means, is provided as means for solving the above-mentioned problem.

According to the present invention, after the core is suctioned by the vacuum suction mechanism of the core suction hand, the core can be freely moved to the target position by moving the core suction hand in the X, Y, and Z-axis directions by the core transport mechanism. Transport to Since the vacuum suction mechanism is swingable, the core can be suctioned by roughly positioning it on the center axis of the core, and the positioning accuracy is reduced.

According to a second aspect of the present invention, the core suction hand has a plurality of pad-type suction cups made of a flexible material, and each suction cup is connected to a vacuum source. The present invention provides a core removing device for solving the above-mentioned problem.

According to the present invention, the use of a soft plastic pad-type suction cup (hereinafter, "suction cup") can further reduce the positioning accuracy with respect to the core during suction. As a vacuum source that gives the suction force to the suction cup, for example, a device that generates a vacuum pressure based on Bernoulli's theorem (a device such as an ejector), a vacuum pump, or the like is used. The present invention also includes selecting a suction cup on which a vacuum pressure generated by a vacuum source is applied by a valve. Accordingly, even when a suction cup that cannot generate suction force is generated due to a damaged portion of the core or the like, it is possible to prevent the suction force of another suction cup from being affected, and to reliably transfer the core by suction.

According to the third aspect of the present invention, the core suction hand has a plurality of pad-type suction cups made of a flexible material, and each suction cup is provided with a separate vacuum suction mechanism. A winding core removing device in a winder, wherein the vacuum source and the suction cup provided are connected to each other, is provided as a means for solving the above problem.

According to the present invention, by connecting the vacuum source individually to each suction cup, even if a suction cup that cannot generate suction power due to a damaged portion of the core or the like occurs, the suction power of another suction cup is reduced.

A core extracting device for winding in a winder, comprising: a core length measuring means for detecting the passage of the front end and the rear end of the core and measuring the length of the core and transmitting a measurement signal. And

According to the present invention, it is confirmed whether or not the target core has been taken out by the core length measuring means. The core length measuring means is connected to a control mechanism such as a CPU, for example, so that when the control mechanism receives the measurement signal of the core length measuring means, the core length is compared with the target core length to determine whether the core is actually taken out. Check. If the measurement core length is different from the target core length, an error signal is transmitted.

In the invention according to claim 5, the core insertion mechanism includes an array holding section for holding the array of the cores whose length has been measured in a line, and a set of cores arrayed and held in the array holding section. A winding core removal device in a winder, which is fed into a winder in a lump, is a means for solving the above problem.

According to the present invention, the cores stored in the array holding section are sent to the winder at once when the core can be inserted in accordance with the operating state of the winder. As a result, even if the number of cores is large, it is possible to send the core to the winder in a short time.

7 (hereinafter, “suction cup 27”) is supported. Each suction cup 2
7, a filter 29 and a hose 30 are connected,
By applying a vacuum pressure generated by the vacuum suction mechanism 21 to the suction cup 27 via the filter 29 and the hose 30, suction power is given to the suction cup 27. In addition, other than the flexible hose, a device using an elastically deformable member made of an elastic body such as rubber can be applied as the swing support means 26.

FIG. 5 shows an example of the vacuum suction mechanism 21.
In FIG. 5, reference numeral 31 denotes an ejector as a vacuum source;
Is a manifold, and 33 is a vacuum holding valve.
The vacuum suction mechanism 21 is a unit including a vacuum holding valve 33 and a filter 29 connected to the ejector 31 via a manifold 32. The ejector 31 is connected to a compressed air flow passage 35 to which compressed air is supplied from a compressor 34, and generates a vacuum pressure based on Bernoulli's theorem by a high-speed airflow generated by the supply of compressed air. The core 7 is sucked by applying a vacuum pressure generated by the ejector 31 to the suction cup 27 via each vacuum suction mechanism 21. Further, when an abnormality is detected in the vacuum pressure of the suction cup 27 when the core 7 is adsorbed,
The vacuum holding valve 33 is closed corresponding to the suction cup 27, and the application of the vacuum pressure to the suction cup 27 is stopped. As a result, even if a suction cup 27 that does not generate a suction force occurs due to a broken portion of the core 7 or a suction position error, the suction force of another suction cup 27 is not affected. In addition,

Pressure does not drop. In addition, a small ejector 3
6 can be used, and the manifold 32 and the valve 33 are not required, so that miniaturization is easy and the structure can be simplified.

Hereinafter, the core insertion mechanism 24 will be described with reference to FIG. The core insertion mechanism 24 includes a guide 38 extending in the X-axis direction, and a core 7 supplied to one end (the left side in FIG. 3) by reciprocating the guide 38. (Not shown).

The core 7 is supplied to one end of the guide 38 via an inclined plate 40. As shown in FIG. 1, the inclined plate 40 is inclined so as to become lower from the stocker 20 toward the guide 38, and the core 7 taken out of the stocker 20 reaches the guide 38 while rolling.

As shown in FIG. 3, stoppers 4 are provided at two lower ends of the inclined plate 40 in the rolling direction of the core 7.
1 is provided, and the stopper 41 protrudes and retreats in the movement locus of the core 7 to permit and regulate the falling of the core 7.
The stoppers 41, 41 alternately move up and down under the control of the control mechanism to supply the cores 7 to the guide 38 one by one. The operation of the stoppers 41, 41
The cylinder 39 which has moved the core 7 supplied from the inclined plate 40 to the other end of the guide 38 returns to one end of the guide 38 again, and at the same time, the next core 7 It is being supplied.

At the center in the length direction of the guide 38, the core 7
A core length measuring means 42 for detecting the passage of the core 7 and measuring the length of the core 7 and transmitting a measurement signal is provided. In FIG. 3, the core length measuring means 42
8 is a light sensor comprising a light-emitting unit 43 and a light-receiving unit 44 which are spaced apart from each other on both sides of the light-receiving unit 8 and measures the length of the core 7 based on the light-blocking time generated by passing through the core 7. As the light emitting unit 43, for example, a photoelectric tube or the like is applied.

The measurement signal of the core length is compared with the target core length set by the control mechanism, and if different from the target core length, an error signal is transmitted. Can be prevented. Thus, the desired core 7 can be accurately sent to the winder side. For example, even if the core 7 having a size different from the original size is erroneously accommodated in the stocker 20, this abnormality can be detected. The core length measuring unit 42 is not limited to an optical sensor, and may be applied to various non-contact detecting units using magnetism, sound waves, ultrasonic waves, radio waves, etc., or contact detecting units using switches or the like. It is possible.

The other end (right side in FIG. 3) of the core insertion mechanism 24 from the core length measuring means 42 is the core 7 whose length has been measured.
Are arrayed and held in a line. A set of cores 7 arranged and held in the array holding section 45
When the core of the winder can be inserted, the cylinder 39 moves to the other end of the guide 38, so that the cylinder 39 is sent to the winder altogether.

In FIG. 3, reference numeral 46 denotes a surface treatment mechanism, which is provided between the core insertion mechanism 24 and the winder, and which performs processing such as tape application and gluing on the surface of the core 7 which is being inserted from the core insertion mechanism 24 into the winder. Is applied.

The operation and effect of this embodiment will be described below. According to the winding core removal device in this winder, the core 7 is sucked by the suction cup 27, transported to the inclined plate 40, and inserted into the winder by the core insertion mechanism 24. The removal of the cores 7 from the stocker 20 is performed according to the arrangement order of the cores 7 from the insertion depth side to the entrance side in the winder, and the removed cores 7 are sequentially supplied to the inclined plate 40. The core 7 supplied to the inclined plate 40 moves while rolling toward the core insertion mechanism 24 due to the inclination of the inclined plate 40. At the lower end of the inclined plate 40, the feed is supplied to the core insertion mechanism 24 one by one by the action of the stoppers 41, 41. The core insertion mechanism 24 sends the supplied cores 7 to the array holding unit 45, where they are serially arranged in the order of insertion into the winder,
When the core 7 of the winder can be inserted, the cylinder 39 is closed.
The cores 7 in the array state are sent to the winder at once.

It is to be noted that several cores 7 can be stored on the inclined plate 40.
It is possible to continuously perform the operation regardless of the operation of inserting the core into the winder by the core insertion mechanism 24.

Therefore, in the winding core unloading device of the winder, it is possible to perform the work of removing the core 7 from the stocker 20 and the arrangement of the removed cores 7 until the next operation of inserting the core 7 into the winder. As a result, work efficiency can be greatly improved. Further, since the cores 7 arranged in the order of insertion into the winder are inserted into the winder at a time, the work time for insertion can be greatly reduced.

Since the suction cup 27 sucks the core 7 using the vacuum pressure generated by the vacuum suction mechanism 21, the suction cup 27 may be positioned at a position where the core 7 can be sucked during the suction work. Compared to using a chuck,
Positioning accuracy can be greatly reduced. Thereby, the requirement for the operation accuracy of the core suction hand 22 and the core transport mechanism 23 is relaxed and the cost can be reduced, and the control thereof can be simplified and the transport operation can be speeded up. This reduction in positioning accuracy is particularly effective when taking out a plurality of types of cores 7 having different diameters, and the speed of the transfer operation is remarkably increased as compared with the conventional configuration.

The suction cup 2 in the core suction hand 22
The number of 7 and the like are not limited to the present embodiment,
It can be changed as appropriate.

[0037]

As described above, according to the winding core removing device in the winder according to the first aspect, after the core is sucked by the vacuum suction mechanism of the core suction hand, the core suction hand is moved by the core transport mechanism. Since the core is freely transported to the target position by moving in the X, Y, and Z axis directions, a plurality of types of cores can be efficiently taken out. In addition, since the positioning accuracy with respect to the core at the time of suction is reduced by using the vacuum suction mechanism, the operation accuracy of the core suction hand and the core transfer mechanism is also reduced, thereby enabling cost reduction and speeding up of the transfer operation. It has an excellent effect.

According to the winding core removing device in the winder according to the second aspect, (1) the positioning accuracy of the vacuum suction mechanism with respect to the core can be further relaxed by using the pad-type suction cup made of a flexible material. Therefore, the speed of the core transfer operation can be further increased. (2) By using the suction cup, when transferring a plurality of types of cores having different diameters, it is almost unnecessary to change the control at the time of core suction by the vacuum suction mechanism, and the speed of the transfer operation can be increased. (3) By installing a vacuum suction mechanism for each suction cup, even if a suction cup that cannot generate suction power due to a damaged portion of the core or the like occurs, the suction power of other suction cups is not affected, and The core can be reliably transported by suction. It has an excellent effect.

According to the winding core removing device in the winder according to the third aspect, the core suction hand has a plurality of pad-type suction cups made of a flexible material, and a separate vacuum suction mechanism is provided for each suction cup. By connecting the vacuum source and the suction cup provided for each vacuum suction mechanism, even if a suction cup that cannot generate suction power due to a damaged part of the core occurs, the suction power of other suction cups is reduced. Since there is no influence, there is an excellent effect that the core can be more reliably suction-conveyed.

According to the winding core take-out device in the winder according to the fourth aspect, whether or not the target core is taken out is confirmed by the core length measuring means, so that the target cores are securely arranged in the target order. Thus, there is an excellent effect that inconveniences such as waste of the wound object due to a mistake in taking out the core can be avoided.

According to the winding core removing device in the winder according to the fifth aspect, when the core can be inserted, the cores held in the array holding section are collectively transferred to the winder in accordance with the operation state of the winder. I decided to send it in,
It is possible to feed a plurality of cores into the winder in a short time, and there is an excellent effect that the winding time of the winder due to the core insertion operation is shortened and the efficiency of the winding operation is improved.

According to the winding core take-out device in the winder according to the sixth aspect, a surface treatment mechanism for pre-treating the core surface is provided between the core insertion mechanism and the winder, and the core is transferred from the core insertion mechanism to the winder. Since the surface of the core is subjected to a process such as tape application or gluing by the surface treatment mechanism during the insertion process, there is no need to separately provide a surface treatment step, and an excellent effect of shortening the operation time is achieved.
