DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for transferring a transfer object such as a bobbin on a carrier.

[0002]

2. Description of the Related Art In order to transport a bobbin in a suspended state, a commercially available bobbin holder is mounted on a carrier of a transporting device with screws protruding from several carriers corresponding to the number of bobbins to be transported, and the bobbin is mounted on the bobbin holder. Suspension is conventionally known. The bobbin is attached to the pins projecting downward from these bobbin holders together with the hollow core. During the work of attaching the bobbin to the bobbin holder, the bobbin core is pushed up excessively, whereby the expanding means is operated, and the bobbin core is fixed to the pin.

[0003]

In such a conventional configuration, each transfer device needs to be provided with a separate bobbin holder for each bobbin, and the bobbin holder remains in the transfer device even after the transfer is completed. In addition, it is necessary to provide a bobbin holder at the transfer destination. However, since known bobbin holders are relatively expensive, it is desirable to minimize the number of bobbin holders used. In the state of the art, the coupling member provided on the carrier is formed integrally with the carrier or attached to the carrier using expensive connecting means.

The present invention has been made in view of the above-mentioned current state of conventional transporting devices, and aims to provide an inexpensive connecting device for transporting devices having a simple configuration.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a transfer apparatus according to a preferred embodiment of the present invention.

FIG. 1 schematically shows a transport device according to an embodiment of the present invention. The transport device 1 is provided with two elongated strip-shaped carriers 2 and 2 ′. A roller shaft 3 is attached to both ends of each carrier 2, 2 ',
The transport device 1 is movably suspended by a roller provided on the roller shaft on a transport rail suspended from a ceiling or the like. Commercially available bobbin holders 5 are arranged below the carriers 2 and 2 'so as to be separated from each other. One bobbin 6 is attached to each bobbin holder 5.
In the illustrated embodiment, three bobbins 6 are attached to each of the carriers 2 and 2 '. However, the number of bobbins attached to the carriers 2, 2 'is not limited to this, and may be increased or decreased as needed.

As shown in FIG. 2, each carrier 2, 2 '
Is formed with a cylindrical through hole 7 at a position where the bobbin 6 is suspended. The through-hole 7 extends in the longitudinal direction of the carriers 2 and 2 ′, and has a large-diameter end 7a opened above the carriers 2 and 2 ′. The large-diameter end portion 7a is connected to an intermediate portion via a tapered portion. Elastic locking member 8 formed by a hollow cylindrical synthetic resin tubular sleeve
Are housed in the through holes 7. At one end of the elastic locking member 8, a locking ridge 9 protruding outward is formed. The lower surface of the locking ridge 9 is formed in a tapered surface 9a, and slots 10 are formed at four diagonal positions of the elastic locking member 8. The slot 10 is formed parallel to the axis from one end of the elastic locking member to an intermediate portion thereof to form an elastic tongue 11 (see FIG. 3).

A rectangular or square flange 12 is formed at the end of the elastic locking member 8 opposite to the end where the locking ridge 9 is provided. The flange 12 is formed so as to protrude outward, and has a size corresponding to the rectangular or square expanded end portion 7b of the through hole 7 formed at the lower portion of the carrier 2, 2 '. The distance between the downward tapered surface 9 a of the locking ridge 9 and the upward surface 12 a of the flange 12 is substantially equal to the length of the intermediate portion of the through hole 7. Therefore, the tapered surface 9a of the locking ridge 9 is joined to the tapered surface connecting the large-diameter end 7a of the through hole 7 and the intermediate portion to form a support surface. on the other hand,
When the elastic locking member 8 is inserted into the through hole 7 from below the carriers 2 and 2 ′, the upward surface 12 a of the flange 12
Joined to the step between the middle part of the through hole 7 and the expanded end 7b,
It functions as a stopper surface for restricting the movement of the elastic locking member 8.

A screw member 13 such as a nut is attached to the inner surface of the elastic locking member 8 at a position corresponding to the position where the flange 12 is formed. A screw 15 provided on the bobbin holder 5 is engaged with the screw member 13, and a lock nut 14 is screwed into an end of the screw 15 protruding from the screw member 13.

A fixing member 16 is provided for fixing the elastic locking member 8 to the through hole 7. This fixing member 16
Is formed in a belt-like shape having the expanding member 17 protruding therefrom.
The expanding member 17 is formed of a synthetic resin into a short cylindrical shape, and has a diameter at least when the expanding member 17 is press-fitted into the inner hole of the elastic locking member 8. The ridge forming portion is slightly displaced outward so as to bring the elastic locking member 8 into close contact with the through hole 7. As shown in FIG. 4, the fixing member 16 is fitted in a groove formed at the upper end of the through hole 7 over the entire length of the carriers 2 and 2 ′. In the configuration shown in the figure, the expanding member 17 is used.
Are arranged so that each fits into the through hole 7.

In order to lock the bobbin holder 5 on which the bobbin 6 is mounted, the elastic locking member 8 may simply be pushed into the corresponding through hole 7 from below. At this time, the elastic tongue 11 is easily pressed and deformed by the upper tapered surface of the locking ridge, thereby allowing the elastic locking member 8 to be pressed into the through hole 7. As shown in the drawing, when the locking ridge 9a enters the large-diameter end 7a, the pressing force on the elastic tongue 11 is released, and the tapered surface 9a of the locking ridge 9 becomes large in diameter as described above. At least the bobbin 6 and the bobbin holder 5 are joined to the tapered surface of the end 7a.
To prevent the elastic locking member 8 from falling off due to its weight. On the other hand, the upward surface 12a of the flange 12 is
Regulates the amount of upward pushing in the through hole 7. When the mounting to all the elastic locking members 8 and the through holes 7 to which the bobbin 6 and the bobbin holder 5 are mounted is completed, the fixing member 16 is mounted to the carriers 2 and 2 ', and the expanding member 17 is mounted.
Is pressed into each elastic locking member 8. Since the elastic tongue piece 11 is pressed outward by the press-fitting of the expanding member 17, the attachment of the elastic locking member 8 to the through hole 7 is further ensured, and the elastic locking member 8 is more careless than the through hole 7. To prevent it from falling off. On the other hand, when the elastic locking member 8 is removed from the carriers 2 and 2 ′ together with the bobbin 6 and the bobbin holder 5, first, the fixing member 16 is removed and the expanding member 1 is removed.
7 is released from the pressing of the elastic tongue. Next, when the bobbin holder 5 is pulled downward strongly, the elastic tongue 11 is elastically deformed inward by the action of the tapered surface 9a of the locking ridge of the elastic locking member 8, and the elastic locking member 8 is moved through the through hole. 7 can be separated.

FIGS. 4 to 6 show two carriers 2, 2 '.

The elastic locking member 8 'is formed in substantially the same shape as the elastic locking member 8 of FIG. In this case, the function of the flange 12 is obtained by the fixed webs 19a and 20a.
The slot 10 'extends to the stationary web 19a.
The elastic locking member 8 'is formed integrally with each of the fixed webs 19a, 20a, and is configured to be locked in the through hole 7 formed in the fixed webs 2a, 2a'. A fixing member 16 having an expanding member 17 'is provided. The length of the expanding member 17 ′ is shorter than that of the expanding member 17 because the length of the elastic locking member 8 ′ is shorter than that of the elastic locking member 8.

The connecting members 19 and 20 are further provided with connecting portions 19b and 20b, respectively. Joint 1
9b has a substantially hemispherical upward outer surface 21;
A substantially hemispherical downward inner surface 22 formed on the coupling portion 20b from above is fitted to the outer surface 21. Outer surface 2
1 and the inner surface 22 have substantially the same dimensions, so that the coupling members 19, 20 can slide relative to each other without play.

A pin 23 is provided through the outer surface 21 and the inner surface 22.
2 'is fixedly attached to a roller shaft 3 common to 2'. A flange 24 whose outer surface is substantially hemispherical is fixed to the pin 23 at a position separated from the roller shaft 3. Pin 23
It is inserted into a through-hole 25 formed in the coupling portion 20b of the coupling member 20. The diameter of the through hole 25 is at least twice the diameter of the pin 23 and twice the width of the flange 24. The pin 23 is further connected to the connecting portion 1 of the connecting member 19.
9b extends to the through hole 26 formed in the through hole 9b. The diameter of the through hole 26 is substantially the same as the diameter of the through hole 25. A projection 27 is formed on the coupling portion 19b. The protrusion 27 is provided in the through hole 26 in a radially inward direction.
It protrudes in the angle range up to °. The protrusion 27 is axially disposed and has a width sufficient to engage the hemispherical flange 24. The projection 27 restricts the movement of the pin 23 in at least one direction in the axial direction.

A sleeve 8 "is used to regulate the downward axial displacement of the pin 23. For this purpose, the through-hole 26 has an enlarged end with a taper when viewed downward in the coupling means. 7a, and is connected to a rectangular or square expanding end 7b through an intermediate portion of the through hole 7.

The coupling member 20 has spherical portions 28a, 28b
Is provided. The spherical portions 28a and 28b are arranged outside the coupling portion 20b and are joined to the spherical portions 29a and 29b formed at the corresponding positions of the fixed webs 2a and 2a '. All spherical surfaces 21, 22, 28a, 28b, 29
a and 29b are configured as spherical surfaces having a common center point. The end of the coupling portion 20b facing the carrier 2 and forming part of the spherical shell fits into a slot 30 in the shape of a spherical shell and extends along a downward inclination angle. The slot 30 is formed between the outer surface 21 and the spherical portion 2.
9a. The spherical portion 29a of the fixed web 2a engages with the coupling member 20 from above to restrict the vertical movement of the coupling member 20. The length of the slot 30 and the dimensions of the coupling portion 20b are set such that a gap is formed below the coupling portion 20b when the carriers 2, 2 'have a positional relationship such that their center lines are aligned. Have been. This gap allows a relative upward and downward displacement of the carriers 2, 2 '. That is, the carriers 2, 2 'can be relatively displaced so that the upper side surfaces form an acute angle. The displacement angle at this time is determined by the size of the gap and the size of the through hole 25. Vertical relative downward displacement in which the upper surfaces of the carriers 2 and 2 ′ form an obtuse angle is allowed by the wedge-shaped space 31. This space 31
The coupling members 19 and 20 are formed by surfaces opposite to the surfaces facing the slots 30. The space 31 is formed around a hemispherical vertical pivot 32. This space 31 is open when the carriers 2, 2 'are arranged in a straight line. The range of angular displacement of the carriers 2, 2 'in the vertical direction is at least 10 ° in both the vertical direction. FIG.
As shown in (2), the carriers 2, 2 'can be angularly displaced in both horizontal directions around the vertical pivot 32 passing through the pin 23 in an angle range of up to 90 degrees. Coupling members 19, 20
The cross-sectional dimensions of the joint 18 formed by this are set such that there are no outward projections at the joint 18 relative to the dimensions of the carriers 2, 2 '.

When the joint 18 is mounted, the two connecting members 19 and 20 are firstly connected to the inner and outer spherical surfaces 21 and 20, respectively.
22 are arranged in a mutually connected state. In this state, the elastic locking member 8 'of the coupling member 20 has already been fitted to the carrier 2'. Next, the elastic locking member 8 ′ of the coupling member 19 is fitted to the carrier 2. As a result, detachment of the two connecting members 19 and 20 is prevented. The roller shaft 3 formed integrally with the pin 23
Before or after joining 2 ′, the joint 18 is disposed along the vertical axis 32 of the joint 18. For this reason, the semicircular flange 24 passes through the through holes 25 and 26 and is fitted from below into the protruding portion 27 in a state of being displaced by 180 ° from the state of FIG. Thereafter, the sleeve 8 "is attached from below. The locking ridge 9 of the sleeve 8" abuts on the lower surface of the semi-circular flange 24 and frictionally engages with the lower surface to dispose the flange 24. Hold in position. The end of the pin 23 located on the other side of the flange 24 is the elastic tongue 1 of the sleeve 8 ″.
The rectangular flange 12 "can be formed as a continuous plate to completely close the opening, as shown in FIG.

FIG. 4 shows a modification of the sleeve 8 "for mounting the bobbin holder 5 of the bobbin 6. This sleeve 8" has a different length from the elastic locking member 8 in the slot formed. In this variant, the slot 10 "extends to the flange 12. The mounting nut 13" is movably received and prevented from being displaced in the rotational direction by suitable means. The nut 13 "is used to fix the screw shaft 15 of the bobbin holder 5. In this example, a through hole 12b is formed in the flange 12", and the screw shaft 15 is inserted through the through hole 12b. Is done.

According to the above modification, the elastic locking member can be used only for connecting the connecting member, can be used for mounting the roller shaft of the carrier, and can be used for mounting the object to be transported to the carrier. You can do it.
It should be noted that a commercially available coupling device can be used instead of the coupling member having the above configuration. In addition, the above-mentioned bonding structure,
It is also possible to apply to a carrier having another configuration. Furthermore, the elastic locking member having the above configuration can be easily applied to the conveyance of a conveyance object other than the bobbin. In addition, it is also possible to provide a through hole in a conveyed article while providing an elastic locking member on the carrier as necessary.
Alternatively, the hole formed in the carrier may be formed as a hole shorter than the thickness of the carrier instead of the through hole, and the elastic locking member may be provided inside the carrier. In the above embodiment, the example in which the expanding member is formed integrally with the belt-shaped fixing member has been described, but each expanding member may be formed independently.

[0026]

As described above, according to the present invention, the holder for holding the article to be conveyed, such as a bobbin holder, can be easily attached to and detached from the carrier, and the holder can be used repeatedly.
The transportation cost can be reduced.
