Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a coiler device for a spinning machine such as a card, a drawing machine, and a comber.

A conventional coiler device has a coiler disc having a sliver outlet, which is eccentrically disposed above a candish plate and is rotatably disposed so that the sliver is accommodated while being coiled in a can placed on the candish plate. When the sliver is housed, the coiler disk rotates while pressingly contacting the upper surface of the sliver housed in the can, causing fuzz on the sliver. Therefore, in the conventional coiler device, the lower surface of the coiler disk is smoothly finished by surface treatment or the like to reduce the friction coefficient, and the sliver disturbance due to the pressure contact with the coiler disk is minimized.

In the conventional coiler device, as is well known, the lower surface of the coiler disk is formed flat over the entire surface, and the lower surface of the coiler disk covers the wide area of the upper surface of the sliver in the can. As a result, the sliver is disturbed (fluffing) due to the pressure contact with the lower surface of the coiler disk. In particular, the sliver in the vicinity of the center of the can has many overlapping portions, and the bulkiness in the up-down direction becomes large. Therefore, there is a problem that the sliver is disturbed in this portion. An object of the present invention is to solve this problem.

Means for Solving the Problems In order to solve the above problems, the present invention rotatably disposes a coiler disk having a sliver outlet at its periphery,
In a coiler device for a spinning machine adapted to house a sliver in a can while coiling, the lower surface of the coiler disk is formed by forming a circular concave portion in which a central portion excluding the peripheral portion is recessed upward, and an annular lower surface of the peripheral portion. Is a contact surface that is in sliding contact with the upper surface of the sliver, and the inside of the recess is an escape space for the sliver in the can facing the recess during coiling.

Action When a can is placed on the candish plate and the coiler device is operated, the candish plate and the coiler disk rotate to accommodate the sliver sent out from the sliver outlet while coiling. In that case, a circular recess is formed in the central part of the lower surface of the coiler disk except the peripheral part, and the sliver in the can in the part facing the recess of the coiler disk enters the escape space in this recess. There is no pressure contact with the bottom surface of the disc, and as a result, the sliver has less fuzz.

Embodiment In the coiler device 1 shown in FIGS. 1 and 2, 2 is a well-known coiler plate, 3 is a coiler disk rotatably supported by a support (not shown), and a sliver outlet 4 is provided near the periphery. is there. Reference numeral 5 is a known candish plate rotatably provided, and reference numeral 7 is a can for accommodating the sliver S mounted thereon. In such a coiler device 1, the sliver S spun from the spinning machine is sequentially coiled into a can 7 rotating at a predetermined position in the figure via a sliver outlet 4 of a rotating coiler disk 3. The lower surface of the coiler disk 3 is formed with a circular recess 3b in which the central portion except the peripheral portion having the same radius as the sliver outlet 4 portion is recessed upward so as not to temporarily contact the sliver upper surface. 3b
The inside is an escape space where the sliver S in the can 7 facing the recess 3b can escape during coiling. The lower surface of the annular peripheral portion where the sliver outlet 4 is located is formed in the same plane as in the conventional case, and serves as a contact surface 1a that contacts the sliver of the can 7. As the can 7, as is well known, a spring can in which a coil spring 8 is interposed between the sliver tray 9 and the inner bottom surface 7a is used.

In the coiler device 1 configured as described above, when the sliver S is housed in the can 7 by rotating the candish plate 5 and the coiler disk 3, the sliver S in the can 7 has the force of the coil spring 8 and the sliver itself. Upper surface of the sliver coil 3 due to the descending force of
The sliver S1 that is pressed into contact with the lower surface of the
The number of turns overlaps and the repulsive force becomes larger. However,
Since the lower surface of the coiler disc 3 is formed with a recess 3b in the central portion, the sliver S in the portion facing the recess 3b escapes into the escape space in the recess 3b and loses pressure contact with the coiler disc 3. The sliver top is
The degree of contact with the coiler disk 3 during coiling is reduced, and a high quality sliver with less fluff can be obtained. The same effect can be obtained even if the present invention is applied to a spin-and-revolve type coiler.

As described above, in the present invention, in the coiler device of the spinning machine, the coiler disk having the sliver outlet is rotatably arranged in the peripheral portion and the sliver is housed in the can while coiling. The lower surface of the coiler disc is formed in a circular recessed portion in which the central portion excluding the peripheral portion is recessed upward to form a ring-shaped peripheral portion as a contact surface in sliding contact with the upper surface of the sliver, and inside the recessed portion during coiling. Since the sliver in the can facing the recess is used as an escape space, the sliver in the can facing the recess escapes into the escape space formed by the recess during coiling, and the upper surface of the sliver is not pressed by the coiler disk. Since the upper surface of the inner sliver is pressure-contacted only by the contact surface of the annular peripheral portion, coiling is performed in such a pressure-contact state. As a result, the degree of contact of the upper surface of the sliver with the coiler disk can be reduced, and a high-quality sliver with less fluff can be obtained. In addition, since the simple structure is such that only the concave portion of the coiler disk is formed, there is an effect that it can be implemented at low cost.
