Description

The spool slewing arrangement

Technical field

The present invention relates to a kind of spool slewing arrangement, especially relate to a kind of can be when keeping spool, the spool slewing arrangement that actv. stops spool to damage.

Description of related art

Usually, use a kind of data cell unit winding apparatus, this device is used for chip-type electronic component being installed to the carrier tape auto reeling on the spool and sending.Wind2 has a S. A. that can keep spool, and this device is arranged to spool and is connected with S. A. and rotatable, thereby the carrier tape of sending continuously can be wound up on the spool.At this, for the structure of S. A. and spool, the S. A. of a certain type shown in Fig. 6 and spool are known.

In Fig. 6, S. A. 80 comprises an axial region 81 that forms round bar, this axial region is tapered towards front end, and three fin 82 intervals 120 on the excircle direction of axial region 81, and each fin stretches out the outside face of axial region 81 and can not stretch by an elastic component (not showing).Equally, spool 83 has the receiving portion 85 that 84, three in a cylindrical shape centre of gration hole that can allow axial region 81 therefrom pass is formed on 84 inboards, centre of gration hole, and the concave part that corresponds respectively to fin 82.

In above-mentioned structure, when a stripe shape carrier tape (not show) when being wound up on the spool 83, at first, spool 83 transmits by a predetermined hold-down arm and axial region 81 is inserted in the centre of gration hole 84.At this moment, if the position of the position of fin 82 and receiving portion 85 does not keep consistent with each other, the elastic force of fin 82 opposing elastic components retracts in the axial region 81.In this state, green phase makes the position of fin 82 and receiving portion 85 keep consistent with each other to spinning reel 83 and S. A. 80, accepts thereby make fin 82 get back to initial position and be accepted portion 85.Therefore, S. A. 80 keeps spool 83.After spool 83 was positioned at an angle of being scheduled to, the leading-in end of carrier tape was inserted in the groove 83A that is formed on the spool 83 by a supply arrangement (not having to show), thus the leading-in end of protection spool 83.Then, by rotation S. A. 80, tape is wound up on the spool 83.

Yet, in the structure of above-mentioned S. A. 80, when the working accuracy of spool 83 hangs down, that is to say, when there was any skew in the position that forms receiving portion 85, perhaps when the width of receiving portion 85 was too narrow, the problem that axial region 81 can not be inserted in the centre of gration hole 84 produced.Accordingly, can be by when forming centre of gration hole 84 and receiving portion 85, have enough tolerance clearances and solve this problem textural.Yet in this case, thereby spool 83 can produce the instability that vibration cause spool 83 location, can compare difficulty when causing that like this leading-in end of tape is inserted into groove 83A.

In addition, when spool 83 was installed on the S. A. 80, because in most cases, spool 83 was to be inserted in the hole when fin 82 is being wiped the inside face in centre of gration hole 84, and centre of gration hole 84 is easily damaged.Especially when using spool made of paper, a problem in addition is the generation of breaking in centre of gration hole 84.In addition, for spool 83 being installed on the S. A. 80 with fin 82, need to prepare a special spool 83 corresponding to fin 82 structures, this exists a problem equally, and promptly spool 83 can not be a general-duty.

Patent documentation 1 (Japanese uncensored public announcement of a patent application 9-314968), patent documentation 2 (Japanese uncensored public announcement of a patent application 10-148889), and patent documentation 3 (Japanese uncensored public announcement of a patent application 11-208049) discloses the structure that S. A. is inserted into the centre of gration hole of spool equally.According to these documents, have the projection of stretching out on the S. A., and this axle is arranged to from the outer circumference surface of axle, accept these projectioies on the axle by being formed on channel shaped otch on the spool centre of gration hole, make S. A. can keep spool.

Yet, according to patent documentation 1-3, keeping the function of spool in order to keep S. A., the material of spool has to have such hardness, promptly can bear the power that acts between projection and the otch.Therefore, when spool is made by a kind of relative softer material, such as paper, a bigger rotational force that is applied on the spool may produce a bigger power around otch, thereby causes otch to break.

Summary of the invention

The present invention considers that above-mentioned problem proposes.Therefore, an object of the present invention is to provide a kind of spool slewing arrangement, this device can be by keeping spool in the middle of spool is clamped in, thereby stop the damage of spool, and this device can how failure-free keeps spool regardless of the structure in spool centre of gration hole, thereby the commonality of spool is strengthened.

In order to achieve the above object, the present invention adopts a kind of spool rotary device structure that comprises a maintaining part, and this maintaining part is used to keep reeling or sending the spool of tape, wherein

Maintaining part can be used for the pair of flanges portion that forms spool is clamped in middle, thereby provides a rotational force to spool.Because the above-mentioned structure different with conventional art, feasible need not being inserted into axle in the centre of gration hole of spool just can keep spool to become possibility.Because this structure, therefore stop the vibration of spool become may and spool can realize accurate localization, also be possible even be inserted under the situation in the groove of spool at the leading-in end of tape.In addition, can not use special spool also to become possibility, thereby can obtain a slewing arrangement with commonality.

In the present invention, a kind of like this structure of preferred employing, promptly maintaining part comprises a contacted main drive division in the outside with a flange part, and the contacted follower in the outside with another flange part; Main drive division and follower can leave each other and be close.Because above-mentioned structure, because main drive division and follower contact with the outside of flange part respectively, when spool was installed and rotate, the damage in centre of gration hole can be prevented from.

Next the whole operation process of the foregoing description will be described.

At this, suppose after the cylindrical shape centre of gration hole R1 of spool R is placed on setting circle cylindrical shell 33 from a conveyer (not having to show) bar 33A goes up, as shown in Figure 5, hold-down arm 34 is in stand up position and makes the flange part R4 of spool R in the face of the side of main drive motor 19.In order to make maintaining part 13 keep spool R at above-mentioned state, at first, bar 33A advances to a position (position among Fig. 5 shown in the long and two-short dash line), leaves a very little gap at the front end of this position bar and fix shaft 16.Then, start clamping and keep cylinder 30 that driven rotor 27 is moved to the right, as shown in Figure 1, fix shaft 16 is inserted among the cylindrical shape centre of gration hole R1 of spool R, and flange part R4 contacts with the contact surface 19A of driving rotor 19.Therefore, spool R is clamped between driving rotor 19 and the driven rotor 27.Under this state, the rotation of the driving rotor 19 by main part 20 and driver element, spool R is subjected to a rotational force.Driven rotor 27 rotations when then, present dynasty's driving rotor 19 compresses spool R.

At this, when being wound up on the spool R, at first, spool R should rotate several times a tape (less than showing) in beginning.Sensor 48 detects the position of circular hole R6 on the spool and the rotation of spool R is stopped on the specific anglec of rotation of spool then.The leading-in end that is arranged so that tape of spool is inserted in the recess R 5 of spool R by a supply arrangement (not having to show), and by spinning reel R under above-mentioned state, leading-in end is maintained in the recess R 5.

When spool R finishes the coiling of tape, near fix shaft 16, driven rotor 27 leaves spool R to the bar 33A of setting circle cylindrical shell 33 once more.Then, keep plate 51 is moved to the left in Fig. 1 bar 33A is inserted among the cylindrical shape centre of gration hole R1 of spool R.Then, hold-down arm 34 rotations, spool R is loaded on the above-mentioned conveyer.

Therefore, according to the above embodiments, when spool R was held, because the surface of driving rotor 19 and driven rotor 27 contacts with the outside face of flange part R4, thereby the load that spool R is born minimized and becomes possibility.As a result, effectively stop the damage of spool R to become possibility.Because this set, though when spool R be when being made of paper, what spool also can be no problem is held.Therefore, improved the selection degree of freedom of the material that is used to form spool R.

Although best setting, method and similarly implement in the superincumbent description of method of the present invention openly, the present invention is not limited only to this.

That is to say, though main detailed the illustrating and describing of a specific embodiment, those of skill in the art can be to the structure of the foregoing description, quantity, position, direction or other detailed structure are made many modifications and are not departed from the technical spirit and the scope of the object of the invention.

Therefore, to the restricted description of structure or similarly describe, this is described in above-mentioned to set forth with mode for example in the description that helps understanding the object of the invention, is not meant to limit the present invention at this.Therefore, it should be understood that any description that the present invention includes any parts, the used title of parts can not carried out some or all of restriction to unit architecture and like configurations.

For example, though the convenience in order to describe, spool R has the structure identical with traditional spool, and middle as long as initiative part 11 and follower 12 can be clamped in spool R, different structural changes is possible.Yet, foregoing embodiment, if having recess R 5 and circular hole R6, a kind of can to keep the structure of the leading-in end of tape automatically be favourable.

Equally, in the above-described embodiment, only have only driven rotor 27 to move up in the structure at right and left.Yet, also can adopt and only have only driving rotor 19 to move up at right and left, perhaps driven rotor 27 and driving rotor 19 structure that can move up at right and left simultaneously is so that driving rotor and driven rotor can leave mutually and be close.

In addition, slewing arrangement 10 can be applied to the spool that is used to send tape.

As previously mentioned, according to the present invention, the formation of maintaining part is in the middle of the flange part of spool is clamped in, thereby and makes a rotational force impose on spool.Therefore, different with traditional technology is, spool need not be inserted into axle spare in the centre of gration hole of spool and just can keep by failure-free, and the vibration that reduces spool becomes possibility.In addition, no matter how, obtaining commonality when spool is held, the structure of rotary middle spindle becomes possibility.

Further say, because forming the initiative part and the follower of maintaining part contacts with the outside of flange part respectively, and can leave mutually and close, this makes when spool is held, thereby has reduced to be applied to the load on the spool and made the damage of prevention spool become possibility.

Say that further when forming an anti-skid structure respectively with the contacted part of spool on initiative part and the follower, the confining force that improves spool becomes possibility, thereby and make the spool that sends to that the rotational force of main drive division can be stable.

Say further that again because the maintaining part on the fix shaft can be inserted in the cylindrical shape centre of gration hole of spool, this makes when spool is held, and is easy to realize the location of spool and accurately keeps the position of the centre of gration of spool to become possibility.
