できるようになっている。(Prior Art) In this type of tape winding device, a plurality of core holders are provided on a common rotating shaft, and a tape is wound around a core held by each core holder. Each core holder is connected to the rotating shaft via a frictional connection. This friction connection part is designed to prevent rotational force of 1 or more from being transmitted from the rotating shaft to the core holder, and if a strong low resistance force in the counter-rotational direction is applied to a specific core from the tape during winding. , slippage occurs in the friction connection of the core,
This prevents the winding force (tension) applied to the tube from increasing.

By applying force, each collar and core holder are brought into pressure contact.

る。(Problem to be Solved by the Invention) However, in the structure of Utility Model Application No. 55-172247M, since the axial force is applied to the entire holder part from one end, the axial direction of each part is Due to variations in frictional force, etc., there is a difference in the frictional force in the rotational direction between the core holder located at the end and the core holder located at the middle, and there is a possibility that the tape cannot be wound with uniform force.

ことが用難であり、空気の漏れが生じやすい。Moreover, it is necessary to attach not only the core holder but also the collar so that it can move freely in the axial direction with respect to the rotating shaft.
The overall structure becomes complicated. In addition, the mechanism for holding the core is driven by air pressure, but as mentioned above, the overall cross-path is complicated, so it is difficult to sufficiently improve the airtightness of the sealing part, and air leaks are likely to occur. .

。Furthermore, since the entire core holder and collar are in pressure contact with each other, if the rotating shaft is bent, the end face of the core holder and the end face of the collar will come into pressure contact with each other in an inclined state, and as a result, the pressure contact force will be distorted. If this occurs, there is a possibility that the winding force cannot be made uniform.

できる。On the other hand, in the structure of JP-A-56-108648, each core holder has an independent air cylinder mechanism built in, so that it can be pressed against the collar without being affected by other core holders, etc. It has become. Therefore, as compared to the case where a common force is applied to the entire part of the core holder as described above, variations in the pressure contact force of each part of the core holder can be controlled.

In other words, since the core holder is in pressure contact with each collar from both sides, if the pressure contact surface of the core holder or the pressure contact φ (of the collar) becomes relatively inclined due to the deflection of the rotating shaft, the pressure contact force will be distorted, and the winding There is a possibility that the force cannot be equalized.

込んだことを特徴としている。(Means for Solving the Problems) In order to solve the above problems, the present invention forms a rotating shaft assembly by fixing a plurality of collars to the outer periphery of a rotating shaft at intervals in the axial direction, and An annular friction block is provided between the collars, and the friction block is provided with a cylindrical outer peripheral wall and first and second annular end walls protruding radially inward from both ends of the outer peripheral wall. , the first @ wall part and the collar slide in pressure contact with each other by the opening surfaces of the collar [to form a frictional connection part that can be connected in such a state that the inner part of both end wall parts)
is slidably fitted to the outer periphery of the rotating shaft assembly in an airtight manner,
An air chamber is formed between both end walls and inside the outer peripheral wall, an air pressure supply control passage is connected to the air chamber, and the pressure receiving area of the first end wall facing the air pressure chamber is equal to the pressure receiving area of the second end wall. The friction block is set larger than the area of the block, and is characterized by incorporating a lug around the friction block to hold an annular Arp winding core.

。(Function) According to the above configuration, the force applied from the pressurized air in the air chamber is greater on the first end wall than on the second end wall, so each friction 10 is applied with the first end wall at the top. The first end wall is moved in the axial direction and is connected to the collar in pressure contact. That is, each of the seven hydraulic blocks presses against the collar on only one side. Further, this pressure contact state is not substantially influenced by the pressure contact state of other frictions or collars.

An axial force is applied to the pressure receiving surface. Then the first end wall portion 21
has an inner diameter smaller than that of the second end wall portion 22 and the inner diameter of the first end wall portion 21
Since the pressure receiving area of is wider than the pressure receiving area of the second @ wall portion 22, the force applied to the first end wall portion 21 is larger than that to the second end wall portion 22.

Since slippage occurs in the friction connecting portion 10, a force corresponding to the above-mentioned resistance force (abnormally large rotational force) is not transmitted from the fixed collar 2 to the screw 3. Therefore, a tension exceeding a predetermined value is not applied to the tape, and no abnormal elongation or the like occurs in the tape.

きる。(Effects of the Invention) As explained above, according to Kihatsuro, each friction block 3 has an independent air cylinder mechanism 7.
is built in, so that it can be brought into pressure contact with the fixed collar 2 without being affected by other friction blocks 3, etc. Therefore, it is possible to prevent variations in the pressure contact force of each friction block 3, and to equalize the winding force.
Because of the difference in the pressure-receiving areas, an axial pressing force is generated on each of the 7 rickshaw blocks 3, so each 7 rickshaw block 3 can be constructed from a single component. Therefore, the structure of the friction block 3 and the seal structure can be simplified, and air leakage can be sufficiently prevented.

きる。Moreover, each friction block 3 has one first end wall portion 2.
1 is in pressure contact with the fixed collar 2, so the rotating shaft 1
Even if the fixed collar 2 is tilted relative to another fixed collar 2 due to deflection, the effect of this is absorbed by the friction coupling part 1.
0 will never be received. Therefore, it is possible to always maintain the pressure contact force of each frictional connection part 10 at a predetermined value and to equalize the winding force.

込んだことを特徴とするテープ巻取装置。A plurality of collars are fixed to the outer periphery of a rotating shaft at intervals in the axial direction to form a rotating shaft assembly, an annular friction block is provided between adjacent collars, and a cylindrical outer circumferential wall portion and a circular friction block are provided between adjacent collars. , first and second annular end walls protruding radially inward from both ends of the outer circumferential wall are provided, and the first end wall and the end surface of the collar are connected to each other so as to be able to press against each other and slide. The inner periphery of the end walls is slidably fitted in an airtight manner to the outer periphery of the rotating shaft assembly, forming an air chamber between the end walls and inside the outer peripheral wall. death,
An air pressure supply control passage is connected to the air chamber, the pressure receiving area of the first end wall facing the air pressure chamber is set larger than the pressure receiving area of the second end wall, and an annular tape is attached to the friction block around the block. A tape winding device characterized by incorporating a lug for holding a winding core.
