2. Description of the Related Art In a creel, a creel frame is horizontally supported along a sliver flowing direction via pillars at a predetermined height position behind a spinning machine, and a plurality of creel rollers are mounted on the creel frame in a flowing direction of the sliver. Is horizontally supported along a direction orthogonal to the creel roller at a predetermined interval, and the rods are arranged at positions lower than the creel rollers so as to be close to and parallel to the creel rollers. Then, a sliver separator and a sliver guide are attached to this rod, and each of the creel rollers is driven to rotate, and each sliver in the supply cans arranged below the sliver is pulled out and guided by the sliver guide to guide the creel roller. Guide it upwards, separate it with the sliver separator without touching it, and spin it It is configured to supply. The sliver separator described above is arranged on the machine base side of the creel roller. Further, the sliver guide described above is also referred to as a snail guide or a ring guide, and is arranged immediately above the center of engagement in which the sliver is accommodated.

In a spinning machine, for example, a drawing machine, usually, 6 to 8 feeding cans are fed to each deliber to transfer the sliver to doubling them. In addition, one or two supply cans are usually arranged below the above-mentioned creel roller, and in order to prevent a large tension from being applied during the transfer of the sliver pulled out from the supply cans, the parts other than above the supply cans are provided. A creel roller is also arranged at the upper part of a certain can exchange passage or just in front of the machine base. Since the sliver separator is provided in order to prevent the sliver drawn from each supply can from contacting each other, it is provided in all the creel rollers. For each creel roller, each sliver drawn from a supply can disposed below the roller and a supply can below each creel roller disposed upstream of the roller. As many sliver separators as necessary to separate each sliver are required.

For this reason, one creel is provided with as many as 100 sliver separators in many cases. Moreover, the sliver separators are fixed by bolts one by one to the rods arranged close to and parallel to the creel roller. For this reason, a lot of labor and time are required for fixing the sliver separator. In addition, the optimum position of the sliver separator and the sliver guide changes every time the diameter of the supply can changes. Therefore, when the size of the supply can is changed, it is necessary to change the fixing positions of the supply cans and fix them again, and a lot of time and labor are spent also on the changing work.

SUMMARY OF THE INVENTION An object of the present invention is to fix a sliver separator and a sliver guide, which are respectively arranged on a large number of creel rollers constituting a creel, to a rod, and to change the fixing position. Is to make it easy.

[0006]

In order to solve this problem, the means adopted by the present invention is that the creel frame is supported horizontally at a predetermined height position behind the spinning machine through a pillar along the flowing direction of the sliver. A plurality of creel rollers are horizontally supported on the creel frame at predetermined intervals along the sliver flowing direction and horizontally along a direction orthogonal to the sliver direction. Are arranged in close proximity to and parallel to the creel roller, a sliver separator and a sliver guide are attached to the rod, and each of the creel rollers is driven to rotate, and inside the supply cans arranged below the creel roller. Pull out each sliver and guide it above the creel roller by the sliver guide. In a creel configured to be supplied to a spinning machine while being separated so as not to come into contact with a separator, an engaging groove is formed along at least one surface of the rod along its length direction, and the engaging groove is provided at an arbitrary position of the engaging groove. The sliver separator and the sliver guide can be engaged and fixed.

[0007]

A rod having a length substantially the same as that of the creel roller is disposed below the creel roller so as to be close to and parallel to the creel roller, and an engaging groove is formed on at least one surface of the rod. Are formed along the length direction. To fix the sliver separator and the sliver guide to the rod, it is only necessary to fix them to the engaging groove of the rod. Therefore, it is possible to easily and quickly fix a large number of sliver separators or as many sliver guides as the supply cans to the rods. Also, if the size of the supply can changes,
Since it is sufficient to move the sliver separator or the like along the engaging groove of the rod and fix the sliver separator at the optimum position, it is easy to change the fixing position.
