2. Description of the Related Art Conventionally, a cheese or cone of a rolling creel for supplying a yarn to be wound on a beam machine or the like without giving a twist such as carbon fiber, monofilament, flat yarn, etc. is rotated when winding the yarn. For this reason, a support shaft is provided vertically on a horizontally rotatable disk-shaped plate that is rotatable, and a cheese or cone bobbin is inserted into the support shaft via a wooden tube to be mounted and supported in a vertical state. .

[0003] However, the replacement of cheese or cone must be performed directly above the support shaft, and the replacement operation is extremely troublesome, and the bobbin of cheese or cone is often made of paper. The dimensional accuracy of the inner diameter of the bobbin is extremely poor, and due to the difference in dimensional accuracy with the wooden pipe, it becomes a shrinking state and the replacement workability deteriorates remarkably. It has a drawback that it cannot be rotated stably due to blurring.

Further, a large number of cheeses or cones are vertically mounted, and the interval between the upper and lower stages must be reduced in order to reduce the size of the creel body. Even if the bobbin inner diameter and the outer diameter of the wooden tube are in a preferable state, the length of the bobbin is shorter than the length of the bobbin of cheese or cone, and is usually about half. There was a drawback that the portion was blurred and could not be rotated stably, and thus could not be evenly wound around the beam machine.

[0005]

SUMMARY OF THE INVENTION The present invention greatly improves the workability of replacing a cheese or a cone, and at the same time, maximizes the braking force to quickly stop the rotation of the cheese or the cone. An object of the present invention is to provide a rolling creel that can handle irregularly-shaped or different-sized cheeses or cones, and that stably retains by elastic restoring force to reduce blur during rotation.

Numeral 7 is a support for supporting a large number of cheeses or cones W arranged at predetermined intervals in the axial direction of the horizontal rods 3, 3a. The vertically extending support shaft 9 is inserted from above into bearings 10, 10a, ... arranged at predetermined intervals in the axial direction of the horizontal rods 3, 3a ... so as to be rotatable in a horizontal state.

In the center of the surface of the plate 8, a spindle
A disc-shaped bobbin holder 12 made of an elastic member such as rubber is provided detachably above the spindle 11, and a lower end surface of a winding thread of a cheese or cone W is provided on other surface portions. Is provided.

On the outer peripheral side of the bobbin holding body 12, notches 14 and 14a, such as appropriately shaped slits and notches, are formed to improve the deformability on the outer peripheral side.

Numeral 15 is a brake mechanism for braking the rotation of each plate 8. The brake mechanism 15 projects a projection 16 outwardly from the outer surface of the bearings 10, 10a,. A horizontal shaft 17 is fixed to 16 in parallel with the horizontal rods 3, 3a... A horizontal lever 17 is provided with a thread guide 18 at one end and a brake pad 19 at the other end. The brake pad 19 on the other end is brought into contact with a friction body 22 provided on the back surface of the plate 8 by the weight moment of the guide post 21 from the swing fulcrum to the thread guide 18 in the free state of the lever 20 when the lever is mounted. The guide post 21 of the lever 20 is in a substantially horizontal state in order to apply a braking force and maximize the braking force.

Reference numeral 23 denotes an intermediate yarn guide.

A pair of thread rings 25, 25a is mounted on a fixed bar 24 which extends laterally in the front-rear direction of the creel body 1 on the outside front side.

Reference numeral 26 denotes a yarn guide.
A large number of reference numerals 26 correspond to the number of cheeses or cones W on the left and right of the front side of the creel main body 1.

Next, the operation of the rolling creel according to the present invention will be described. In the state where the warp is supplied to a beam machine or the like (not shown), the cheese or the corn W is placed in the upper part of the bobbin W1. Since the bobbin holding body 12 is fitted by its elastic restoring force, the shaft runout during rotation is reduced, and the brake mechanism 15 during winding is used as the lever 20 by the tension applied to the warp. Since the guide post 21 is maintained in a state of being inclined upward from substantially horizontal, the brake pad 19 at the other end of the lever 20 is released from the friction body 22 and the braking force is released.

When the tension is lost due to the warp cutting or the like, when the guide post 21 becomes horizontal due to the weight moment of the guide post 21 of the lever 20, the brake pad 19 at the other end is brought into contact with the friction body 22. The plate 8 comes into contact with the brake pad 19 and the frictional member 21 to apply a braking force to the plate 8 to stop the rotation.

With respect to the braking force, the guide post 21
, The braking force is maximized.

Next, regarding the replacement work of the cheese or cone W, first, the cylinder 5 connected to the horizontal rods 3, 3a... By rotating the rods 3, 3a... By a predetermined angle, the attitude of the plate 8, which has been in the horizontal state, is changed to the inclined state, and in this attitude, the cheese or cone W on which the warp is wound is pulled out obliquely upward, and then the warp is The bobbin holding body 12 to be mounted on the spindle 11 is fitted to the bobbin W1 of the wound cheese or cone W.

For such a mounted state, the bobbin holder
12 has elasticity, so that it can absorb the dimensional difference of the inner diameter of the bobbin W1, stably holds the cheese or cone W by the elastic restoring force, and the length of the spindle 11 makes the plate 8 inclined. As a result, the length of the bobbin W1 can be made substantially the same as the length of the bobbin W1, so that the portion supported by the bobbin holder 12 can be an upper portion in the bobbin W1.

[0022]

According to the present invention, the horizontal rods 3, 3a... Are rotatably suspended at predetermined intervals in the vertical direction of the creel main body 1, and the cheese or the cheese is disposed at predetermined intervals in the axial direction of the horizontal rods 3, 3a. A plate 8 for supporting the cone W is disposed so as to be horizontally rotatable, and a guide post 21 for mounting a thread guide 18 at one end on a horizontal rod 3, 3a... Below the plate 8, and a brake pad at the other end. Attach the lever 20 that is provided with 19 to swing freely,
When the lever 20 is free and the guide post 21 is in a substantially horizontal state, the brake pad 19 is brought into contact with a friction member 22 provided on the back surface of the plate 8, and the horizontal rods 3, 3a are connected to the cylinder 5. Since the plate 8 is tilted by the operation of the cylinder 5, it is possible to change the posture of the plate 8 to the inclined state and mount the cheese or the cone W, thereby greatly improving the replacement workability. In addition, the levers 20 constituting the brake mechanism are provided on the horizontal rods 3, 3a... To provide the maximum braking force when the plate 8 is in the horizontal state, and the rotation of the cheese or cone W is stopped promptly when the thread breaks. I can do it.

Further, since the disk-shaped bobbin holding member 12 made of an elastic member such as rubber is provided above the spindle 11 erected at the center of the surface of the plate 8, the dimensional difference of the inner diameter of the bobbin W1 is absorbed by elastic deformation. Bobbin W
1 It is possible to cope with irregularities in the inner diameter and cheeses or cones W of different sizes, and to stably hold the cheeses or cones W by the elastic restoring force. The defect can be eliminated, and the length of the spindle 11 can be changed by making the plate 8 in an inclined state, so that the bobbin W1 can be replaced.
, And the portion supported by the bobbin holder 12 can be formed as an upper portion in the bobbin W1. Thus, the bobbin W1 can be stably held so as to further reduce shake during rotation. Its practical effect is as great as possible.
