Abstract

PURPOSE:To certainly stop a shaft and a winding core at the position forming a concentric circle by allowing the outside diameter dimension of the shaft to be spread and contracted and stopping the rise of an elevator board by detecting the difference between the spread diameter and contracted diameter. CONSTITUTION:A transfer frame 24 is lowered for a winding core 10 or a coil installed onto a feeding shaft 8 whose diameter is spread, and a detecting pin 25 is pushed onto the winding core 10. Then, a detecting dog 25b is raised, and when it reaches the position corresponding to a detector for the constant position of the coil, lowering of the transfer frame 24 is suspended. When the diameter of the shaft 8 is contracted, the winding core 10 lowers by that portion, and also the detecting pin 25 and the dog 25b lower by the equal quantity. Then a coil car 11 for the winding core 10 or coil is raised, and when the dog 25b reaches the position of the detector for the constant position again, the rise of the coil car 11 is suspended. Therefore, the shaft 8 and the winding core 10 are certainly stopped at the position of concentric circle. Therefore, the winding core can be taken out certainly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for taking out a shaft attachment such as a coil or a winding core set in a cantilever type feeder or winder from the shaft.

[Conventional technology]

Conventionally, a structure shown in Fig. 8 has been known as a mounting for taking out a shaft-mounted object such as a coil or a winding core from a cantilever type feed-out shaft (Utility Model Application No. 57-74323).
Publication No.). That is, this take-out device detects the weight of the coil 2 on the pallet 1 with a pressure switch 3, and in response to a predetermined signal from the pressure switch 3, the lifting of the coil car 4 by the coil car lifting cylinder 5 is stopped. In this take-out device, as shown in FIG. 9, the coil car 4 is raised to a state where the contracted delivery shaft 6, the coil 2, and the winding core 7 form concentric circles, and in this state, the coil car 4 is moved vertically toward the front in the plane of the paper. The remaining coil 2 and winding core 7 are removed from the feed shaft 6 by running the coil.

[Problem that the invention seeks to solve]

By the way, in the conventional pressure detection type take-out device configured as described above, the change in the weight of the coil 2 when the coil car is raised is detected by the pressure switch 3, and the rise of the coil car 4 is stopped based on the detection signal. It looks like this. However, for example, when only the winding core 7 remains on the delivery shaft 6, there is almost no weight change when the coil car rises, and therefore no pressure rise occurs, so the pressure switch 3 does not operate and this occurs. The pressure switch 3 does not issue a signal to stop the coil car 4 from rising. Therefore, the coil car 4 continues to rise as it is, and there are drawbacks such as the fact that the feed ratio shaft 6 ends up being pushed up, or the precision with which the coil car 4 stops rising is disrupted.

The object of the present invention has been made in view of the above-mentioned drawbacks.
Regardless of changes in the weight of the shaft-mounted object (coil, winding core, etc.), the coil car can be stopped at a position where the gap between the shaft and the winding core is the same on the circumference for shaft-mounted objects of any weight. The present invention provides a device for taking out objects mounted on a shaft such as coils.

[Means for solving problems]

The device for taking out objects attached to a shaft such as a coil of the present invention has a structure in which the outer diameter of a cantilever-supported shaft on which a shaft attachment such as a coil is attached can be expanded or reduced, and the enlarged diameter of this shaft is The purpose is to detect the difference between the reduced diameter and the reduced diameter and stop the lifting platform, thereby achieving the above-mentioned purpose.

[Effect]

In the present invention, the shaft is first made to have an enlarged diameter, and in this state, the upper surface of a shaft-mounted object such as a coil is detected by a detector, and then the shaft is deformed to a reduced diameter. Thereafter, the platform is raised, and when the coil or other shaft attachment comes into contact with the detector again, a stop signal is issued to stop the platform.

[Example] Hereinafter, the present invention will be described in detail using examples shown in the accompanying drawings.

1 to 4 are diagrams showing a device for taking out shaft-mounted objects such as coils according to the present invention. The take-out device of this embodiment includes a coil 9 attached to a sending shaft 8 of a cantilever type sending machine,
A device is shown in which a shaft-mounted object such as a winding core 10 is automatically taken out from a feeding shaft 8. As shown in FIG. 1, the coil 9 is placed on a pallet 12 disposed on the upper end side of the coil car 11, and
1 is configured to be able to be raised and lowered by a coil car lifting cylinder 13. Further, the coil car 11 can run on guide rails 14 arranged along the direction perpendicular to the plane of the drawing. Furthermore, the sending shaft 8 is
Its outer diameter can be enlarged or reduced, and one end is supported in a cantilever manner by a support means (not shown). Note that since the above structure is already known, further detailed explanation will be omitted.

As shown in FIG. 1, a fixed frame 15 is disposed above the coil 9, and a lock-up cylinder 16 is attached to the fixed frame 15. A lifting frame 18 is fixed to the lower end side of the rod 17 of this lock-up cylinder 16, and this lifting frame 18 has a structure in which it is constantly pressed downward by a spring 19, and when the coil car is pushed up, the lifting frame 18 is It is designed to be able to rise against the elastic force of 19. As shown in FIG. 2, a rising frame guide shaft 20 is fixed to the left and right positions of the rising frame 18 centering on the position of the lock-up cylinder 16, and this guide shaft 20 is held by a spring 20H. It has a structure that is always pressed downward.

Further, a magnetic bar fixing shaft 21 for measuring tape passes through the rising frame 18, and a movable frame guide shaft 22 is supported therethrough, and the upper ends of the magnetic bar fixing shaft 21 for measuring tape and the moving frame guide shaft 22 are supported. The parts are connected to each other by brackets 23. Furthermore, these shafts 21.22
A moving frame 24 is fixed to the lower end of the frame.

A coil detection pin 25 is attached to the movable frame 24 so as to be able to move up and down with the coil detection pin 25 projecting downward.
As is clear from FIG. 2, a coil (18! pad 26) is fixed to the lower surface of the moving frame 24 at the upper end of the shaft 25a supporting the coil detection bin 25. As is clear from FIG. 4, the coil fixed position detector 27 is fixed to the movable frame 24 via a support 28, a bracket 29, etc., so as to be located around the coil detection bin 25. Further, around this coil detection bin 25, in addition to the coil fixed position detector 27, a coil detection bin origin position detector 30 and a coil car push-up detector 31 are installed on pillars 32, 33 and brackets 34, 35. The coil car push-up detector 31 is disposed above the coil fixed position detector 27.

Next, the operation of the device configured as above will be described. First, the means for extracting the coil 9 from the delivery shaft 8 will be explained with reference to FIGS. 5 to 7. During coil feeding, the moving frame 24 waits upward.

After the coil is sent out, the moving frame 24 is lowered,
The coil detection bottle 25 is pressed against the upper surface of the coil 9. Then, the detection dog 25b rises, and the detection dog 2
5b comes to a position corresponding to the coil localization lid detector 27, the movement frame 24 is stopped from lowering. Note that during the above operation, the outer diameter of the delivery shaft 8 is in an expanded state as shown in FIG.

Next, the outer diameter of the delivery shaft 8 is changed from an expanded state to a reduced state.

Then, as shown in FIG. 6, the coil 9 is lowered by the difference H between the enlarged diameter and the reduced diameter of the delivery shaft 8, and the coil detection bin 25 and the detection dog 25b are also lowered by the same amount. After that, when the coil car 11 on which the pallet 12 is placed is raised, the coil 9 resurfaces, and the coil detection bin 2
5 and the detection dog 25b are lifted again. Then, when the detection dog 25b reaches the position of the coil fixed position detector 27, a stop signal is issued to stop the coil car 11 from rising. As a result, the coil 9 and the winding core 10 stop at a position concentric with the feed-out shaft 8, as shown in FIG. 7, and the circumferential gap between the winding core 10 and the feed-out shaft 8 is uniform becomes.

Thereafter, in FIG. 7, the coil car 11 is run perpendicularly to the front of the page, and the coil 9 and winding core 10 are fed out to the feeding shaft 8.
extract it from

Next, a procedure for removing the winding core 10 from the delivery shaft 8 when only the winding core 10 remains on the delivery shaft 8 will be described. During coil feeding, the moving frame 24 waits upward, as described above. After the coil has been fed out, the movable frame 24 is lowered and the coil detection bin 25 is pressed against the winding core 10 as indicated by the two-dot chain line 25° in FIG. Then, as the movable frame 24 descends, the detection dog 25b rises, and when the detection dog 25b rises to the position of the coil fixed position detector 27, the movable frame 24 stops descending. let

Note that during the above operation, the outer diameter of the delivery shaft 8 is in an expanded state.

Next, the outer diameter of the delivery shaft 8 is changed from an expanded state to a reduced state.

Then, in the winding core 10, only the difference between the inner diameter of the winding core 10 (that is, the enlarged diameter of the feeding shaft 8) and the reduced diameter of the feeding shaft 8 decreases, and accordingly, the coil detection bin 25 and the detection dog 25b also decrease by the same amount. Then, when the coil car 11 with the pallet 12 placed thereon is raised, the winding core 10 resurfaces, and the coil detection bin 25 and detection dog 25b are lifted again. Then, when the detection dog 25b reaches the position of the coil fixed position detector 27, a stop signal is issued to stop the coil car 11 from rising. As a result, the winding core 10 stops at a position concentric with the delivery shaft 8, and the gap between the delivery shaft 8 and the circumference of the winding core 100 is maintained uniform. After this,
If the coil car 11 is run perpendicularly to the front in FIG.

Incidentally, in the above-described operation, when the coil fixed position detector 27 fails to detect the detection dog 25b, the coil car 11 continues to rise. At this time, the coil car installed above the coil fixed position detector 27 detects the detector dog 25b by the push-up detector 31, stops the coil car 11 from rising, and moves the moving frame 24 up and away. I have to. If the coil car 11 does not stop rising even with this coil car push-up detector 31, the winding core 10 (if only the winding core 10 remains on the feeding shaft 8) hits the coil protection pad 26, and the spring 19.20a The lifting frame 18 is lifted by overcoming the elasticity of the lifting frame 18. As a result, the rising frame detector 36 is activated when the coil car is pushed up.
The raising of the coil car 11 is stopped and the moving frame 24 is raised and retreated. As described above, the delivery shaft 8 is doubly prevented from being damaged or deformed due to excessive rise of the coil car 11, and safety is ensured.

In addition, in the above-mentioned embodiment, a case was described in which the coil and winding core attached to the feed-out shaft of a cantilever type feed-out machine were taken out, but the invention is not limited to this. Needless to say, the present invention can also be applied to the case of taking out a coil or winding core attached to a machine.

〔Effect of the invention〕

As explained above, according to the present invention, the outer diameter of the shaft can be expanded or contracted, and the difference between the expanded diameter and the contracted diameter is detected to stop the lifting platform. So,
Even if only the winding core remains on the shaft, it is possible to reliably stop the platform at a position where the shaft and winding core are concentric circles (a position where the gap between the shaft and the winding core is the same on the circumference). It has become possible.

In addition, when removing shaft-attached items such as coils and winding cores from the shaft, conventionally the operator manually raised the lifting platform while visually checking that the gap between the shaft and the winding core was even around the circumference. Previously, the equipment had been stopped, but with this device it is now possible to automatically remove the shaft attachments from the shaft, making it unmanned.
