Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for moving a pair of support shafts from both ends of a roll body toward a center side to support the roll body while sandwiching the roll body.

[0002]

2. Description of the Related Art For example, when a warp is pre-dyed in a warp preparation process and then set on a sizing apparatus, a hollow cylindrical beam having no support shaft as a center is used as a warp beam. This is because by forming a large number of through holes in the yarn winding surface of the beam, when the dye is immersed in the dye with the beam in the state where the warp is wound around the beginning of blooming, the dye is
This is to allow the warp to permeate not only from the outside of the beam but also from the inside.

When the hollow cylindrical warp beam as described above is used, the roll support device of the beam stand in the gluing device does not support the pouring shaft,
A type that supports the warp beam while sandwiching it from both sides is used. As described above, a supporting device that supports a hollow cylindrical roll body generally includes a support shaft and a holder supported at the tip of the support shaft, moves the holder from both axial sides of the roll body, and places the roll body in a holder. A type which is supported by being sandwiched between support shafts via a shaft (for example, Japanese Patent Application Laid-Open No. 1-162658).

[0004] The operation of mounting the roll body on the above-described support device is performed as follows.

[0005] First, the roll body is transported upward between the support shafts by a suitable transport elevating device such as an electric hoist or a manual chain block (transport step).

Next, the roll body is moved up and down so that the axis of the roll body coincides with the axis of the left and right support shafts (elevating step).

Then, one support shaft is moved to the roll body, the holder is fitted to the roll body and fixed, and the other support shaft is moved to the roll body to fit the holder to the roll body and fixed ( Mounting process).

[0008]

However, in the above-mentioned conventional supporting device, the work of mounting the roll body is complicated, and requires a long time and a large amount of labor for the following reasons.

Since the axes of the roll body and the support shaft must be aligned for mounting, a delicate position adjustment is required in the process of lifting and lowering the roll body.

In the transportation process, it is difficult to make the roll body completely horizontal, so that the roll body is carried in an inclined state in which one of the right and left sides is downward. For this reason, in the mounting process, the height position of one end of the roll body is aligned with the one support shaft, and one support shaft is fitted to one end of the roll body. After adjusting the height position of the other end of the body to the other support shaft, it is necessary to perform an operation of fitting the other support shaft to the other end of the roll body.

[0011] In particular, the above-mentioned problem becomes more conspicuous as the weight of the roll body increases, as in a warp beam wound with a warp.

Therefore, in a device that supports the roll body while holding the roll body by moving the pair of support shafts, it is important to facilitate the work of mounting the roll body.

[0013]

A roll support device according to the present invention includes a pair of support members each supported by one end of a support shaft and provided so as to be able to advance and retreat between a standby position and a support position. The roll body is lowered between the support members and the support member is moved from the standby position to the support position, and the roll body is supported while being sandwiched by the support shaft in a state where the roll body and the support member are fitted.

Such a supporting device includes a guide portion formed so as to protrude from one of the support shaft and the roll body, the guide portion having a guide surface facing the other of the support shaft and the roll body in the vertical direction. Including. The guide surface abuts on the other side at a position where the axis of the support shaft and the roll body coincide with each other in a state where the support member is at the standby position, and the contact state is changed by the movement of the support member. Are maintained until they are fitted.

When the roll is lowered between the two support members, the guide formed on one of the support member and the roll comes into contact with the other of the support shaft and the roll. Are supported by the support member and the support shaft via the guide portion in a state where the axes are aligned. In this state, the support shaft is moved with respect to the roll body, and the support shaft and the roll body are in a fitted state, and the roll body is supported while being sandwiched between the two support shafts.

Therefore, according to the present invention, since the positioning of the roll body with respect to the support shaft is performed only by lowering the roll body, the positioning of the roll body with respect to the support body is facilitated. Further, since the roll body is supported in a positioned state by the guide portion, the work of mounting the roll body can be performed easily and in a short time.

In a preferred embodiment, the support member is a holder which is fitted in a state where the supported portion of the roll body is surrounded, and the guide portion projects a part of a portion of the holder surrounding the roll body. It is formed.

In the present invention, the term "standby position" refers to a state in which a pair of support members are separated from each other so as to receive a roll member therebetween, and the term "support position" refers to a support position in which the roll member is in a support state. Refers to the position of the member.

Referring to FIG. 10, a plurality of supporting devices 1 provided on a beam stand 20 in a warp gluing device.
0 supports the warp beam 12 as a roll body on which the warp 22 is wound, and the corresponding warp beam 1
From 2, the warp yarn 22 is drawn out in a sheet shape. The drawn out warp yarn 22 is first guided by a sizing machine 24 to be pasted, passes through a drying device 26, and is then wound up by a rewinding machine 28 onto a loom beam 30.

As shown in FIGS. 1 and 2, the beam stand 20 has a plurality of wheels 36 mounted on a base formed by a pair of base members 32 and a plurality of cross beams 34 to form a bogie. The support devices 10 are arranged at intervals in the longitudinal direction of the base member 32, and the cart is movably mounted on a plurality of rails 38.

In the example shown in FIGS. 1 to 3, the warp beam (roll body) 12 has a ring-shaped auxiliary member 14 provided on the outer periphery of both ends of a hollow cylindrical main body portion 16, and a support shaft described later. The end which functions as a supported part which is supported while being fitted into and sandwiched by 40 (or 42) is
It is reinforced by.

As shown in FIG. 3, one of the auxiliary tools 14 has a short cylindrical portion 14a fitted to the outer periphery of the end of the main body portion 16, and an outer portion integrated with the cylindrical portion 14a. It has an L-shaped cross-sectional shape by the orientation flange portion 14b.

Referring again to FIG. 1 to FIG.
Reference numeral 0 includes a pair of support shafts 40 and 42 that are opposed to each other at an interval in the longitudinal direction of the cross beam 34. Support shafts 40 and 42
Each of the pillars 4 extends upward from the base member 32.
4 is movably received in the axial direction by a boss portion 46 provided at the upper end.

The support shaft 40 located on the left side is hand-weave movably and non-rotatably received by the corresponding boss 46, and the front end (the end on the support shaft 42 side) of the support shaft 40 has a support shaft. A holder (supporting member) 50 is provided rotatably mounted around a shaft 40 by a bearing. The support shaft 40 is moved in the axial direction with respect to the boss portion 46 by pushing and pulling the rear end portion by hand, and the holder 50 is also moved accordingly.

The support shaft 40 in the axial direction of the boss portion 46
Is locked by the locking means 52 so as to be releasable. The locking means 52 includes a female screw member provided on the corresponding boss portion 46, a lock screw that is screwed into a screw hole of the female screw member and that removably prevents the movement of the support shaft 40,
And a handle for manually rotating the lock screw.

The support shaft 42 located on the right side is movably and non-rotatably received by the corresponding boss portion 46, and has a tip (an end on the support shaft 40 side) of the support shaft 42. A holder (support member) 56 is provided. Support shaft 4
2 is a screw rod 58 which is screwed into a screw hole formed at the rear end.
Is rotated by the handle 60, thereby being manually moved in the axial direction.

The support shaft 42 in the axial direction of the boss portion 46
Is releasably locked by the locking means 62. As shown in FIG. 3, the locking means 62 is provided with a female screw member 64 provided on the corresponding boss portion 46 and a lock screwed into the screw hole of the female screw member 64 so as to releasably prevent the rotation of the screw rod 58. A screw 66 and a knob 68 for rotating the lock screw 66 are provided. The movement of the support shaft 42 with respect to the boss portion 46 is performed by blocking the rotation of the screw rod 58 with the lock screw 66 in the illustrated example.

One of the holders 50 and 56 is shown in FIG.
As shown in FIG. 3, a disk-shaped base 70 and a short peripheral wall 72 projecting from the outer periphery of the base 70 in the longitudinal direction of the corresponding support shaft 40 (or 42) are integrally formed. A part of 72 is further protruded in the longitudinal direction of the corresponding support shaft 40 (or 42) to form a tongue-shaped guide portion 74 curved in an arc shape.

The warp beam 12 is lowered from above between the support shafts 40 and 42 and is held by the holders 50 and 56.
When gripping the warp beam 12, each peripheral wall 72 receives the end (supported portion) of the warp beam 12 and the guide portion 7.
The inner surface of 4 acts as a guide surface 76 for guiding the outer periphery of the end of the warp beam 12 into the peripheral wall 72.

The peripheral wall 72 has a pair of notches 80 for receiving a projection 78 formed on the outer periphery of the end of the warp beam 12. When the projection 78 is received in the notch 80, the relative rotation between the warp beam 12 and the support shafts 40 and 42 is prevented.

The holder 50 includes a peripheral wall 72 and a guide portion 74.
Is extended toward the front end side (the side of the support shaft 42).
It is mounted concentrically by a bearing at the leading end of the "0" so as to be rotatable around its axis.

The holder 56 includes a peripheral wall 72 and a guide portion 74.
Is extended to the front end side (the side of the support shaft 40).
2 are concentrically assembled with a plurality of screw members. The drum 82 is concentrically mounted on the distal end of the support shaft 40 by a bearing so as to be rotatable around its axis. Thus, the holder 56 is rotatable about the axis of the support shaft 42.

The support shafts 40 and 42 are supported by the corresponding bosses 46 in such a state that their axes coincide with each other and the peripheral wall 72 and the guide surface 76 face each other. The radius of curvature between the inner surface of the peripheral wall 72 and the guide surface 76 is such that the end (supported portion) of the warp beam 12 to be gripped is received in the peripheral wall 72 in a fitted state. In particular, it is the same as the radius of curvature of the outer periphery of the cylindrical portion 14a.

For this reason, the warp beam 12 is connected to both guide portions 7
4, the center axis of the warp beam 12 is
Even if the axes are slightly shifted from the axes 0 and 42, the supported portion of the warp beam 12 naturally moves along the guide surface 76, and the axes of the warp beam 12 and the two support shafts 40 and 42 coincide.

Here, "coincidence" and "same" mean not only a design error but also the warp beam 12 or the holder 50,
The edges of the 56 are chamfered so that even if their axes are shifted to some extent, the end of the warp beam 12 is guided by the chamfered surface and the holder can be fitted into the peripheral wall 72. In such a case, such a deviation range is included.

The projecting length of the guide portion 74 depends on the warp beam 1.
The second end is set to a value that does not interfere with the flange portion 14b of the warp beam 12 in a state where the end portion is in contact with the base 70 of the holder. The circumferential length of the guide portion 74 is equal to the warp beam 1.
The end of the warp beam 12 is set to a value equal to or less than half the circumference of the end of the warp beam 12 so that the end of the warp beam 12 can be received from the side facing the guide surface 76.

The drum 82 is a drum of a brake device for applying a braking force to the warp beam 12. The brake device adjusts the tightening force of the band 84 wound around the drum 82 by the cylinder mechanism 86. The cylinder mechanism 86 includes a bracket 90 mounted on the support shaft 42.
Attached to. The band 84 has one end connected to the piston of the cylinder mechanism 88 and the other end connected to the bracket 90.

Next, the operation of mounting the warp beam 12 on the support device 10 will be described with reference to FIG.

As shown in FIG. 5A, the warp beam 12
Is firstly moved upward between the support shafts 40 and 42 by a suitable lifting device such as an electric hoist or a manual chain block, and then lowered toward the space between the support shafts 40 and 42.

At this point, the support shaft 40 has already been set so that the distance between the tips of the guide portions 74 is smaller than the length of the warp beam 12 and the distance between the ends of the peripheral wall 72 is larger than the length of the warp beam 12. , 42 are maintained in the standby position. The holders 50 and 56 have a heavier portion on the side having the guide portion 74 than the other portions.
Is the lower side. Therefore, when the warp beam 12 is mounted, the guide surface 76 faces the end of the descending warp beam 12, that is, the supported portion.

In the descending process, the warp beam 12 is received by the guide portion 74 with the cylindrical portion 14a abutting on the guide portion 74 of the holder as shown in FIG. Thereby, the positioning of the warp beam 12 with respect to the holders 50 and 56 is automatically performed. When the warp beam 12 is received by the guide portion 74, the axes of the warp beam 12 and the support shafts 40 and 42 coincide with each other as described above.

Next, as shown in FIG. 5C, the support shafts 40, 42 are advanced to a support position where the base 70 of the holders 50, 56 abuts on the end of the warp beam 12. Since the radius of curvature between the inner surface of the peripheral wall 72 and the guide surface 76 of the guide portion 74 is the same, and the inner surface of the peripheral wall 72 and the guide surface 76 of the guide portion 74 are continuous without interposing a step, the support shafts 40 and 42 are provided. When the arm moves with respect to the warp beam 12, the support shafts 40 and 42 move smoothly with respect to the warp beam 12. The guide surface 76 keeps the warp beam 12 until the support shafts 40 and 42 and the warp beam 12 are fitted.
And supports the warp beam 12.

To remove the warp beam 12 from the support shafts 40, 42, the above operation may be performed in reverse. In both cases of attaching and releasing the warp beam 12 to and from the support device 10, the support shafts 40 and 42 can be manually moved in a state where the lock functions of the lock means 52 and 62 are released, respectively.

In the embodiment shown in FIG. 1, the support shafts 40, 4
2. The left and right structures of the support device, such as the mechanisms and means related thereto, are different, but the left and right structures may be the same.

In the embodiment shown in FIG. 1, as shown in FIGS. 6A and 6B, the guide portions 7 are provided on the holders 50 and 56 side.
4, but the present invention is not limited to this.

For example, as shown in FIGS. 7A and 7B, a guide portion 92 protruding toward the support shafts 40 and 42 may be formed on the warp beam 12 side. The radius of curvature of the inner surface of the guide portion 92 is the same as the radius of curvature of the outer peripheral surface of the peripheral wall 72, and the inner surface of the guide portion 92 continues from the front end to the rear end without a step. The end of the warp beam 12, that is, the supported portion is fitted into the peripheral wall 72 of the holder 50, 56, while the guide portion 92 is in contact with the outer peripheral surface of the peripheral wall 72.

In the above embodiment, the end (supported portion) of the warp beam, which is a roll, is fitted into the holder. However, the present invention is not limited to this. It may be of a type fitted into a hollow part.

For example, as shown in FIGS. 8A and 8B, a guide portion 94 protruding toward the holders 50 and 56 is formed at the end of the warp beam 12, and a central portion 96 of the holders 50 and 56 is formed. May be fitted into the hollow portion of the roll body 12. The radius of curvature of the inner surface of the guide portion 94 is the same as the radius of curvature of the inner peripheral surface of the end portion of the warp beam 12 and the outer peripheral surface of the central portion 96 of the holder, and the inner surface of the guide portion 94 has a stepped portion on the inner surface of the warp beam 12. Continue without intervention.

As shown in FIGS. 9A and 9B, guide portions 98 projecting toward the warp beam 12 are formed on the support shafts 40, 42, and the center portions 9 of the holders 40, 42 are formed.
4 may be fitted into the end of the warp beam 12. The radius of curvature of the outer surface of the guide portion 98 is the same as the radius of curvature of the outer peripheral surface of the end portion of the warp beam 12, and the inner surface of the guide portion 98 is continuous from the front end to the rear end without a step.

In any of FIGS. 7, 8 and 9, the inner surfaces of the guide portions 92, 94 and 98 function as guide surfaces. In the case of the embodiment shown in FIGS. 7 and 8, when the roll body is moved up and down with respect to the support shaft, the guide portions 92 and 94 are maintained upward. Further, in the case of the embodiment of FIG. 8, the guide portion 94 may be fitted into a part of the holder to prevent the relative rotation between the roll body and the support shaft.

The present invention can be applied not only to a warp beam but also to an apparatus for supporting another roll body such as a cloth-wound roll, a roll for winding a sheet-like member such as paper or film.

The present invention is not limited to the above embodiment. The present invention can be variously modified without departing from the gist thereof.
