Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a spinning pack fixing base in a spinning pack assembling / disassembling apparatus.

[0002]

2. Description of the Related Art A filament manufacturing apparatus manufactures a continuous multifilament by heating and melting a raw material chip (a lump of a polymer having a certain shape), filtering the polymer, and extruding the polymer through a fine pore with a lightweight pump. In addition, a component unit of a high-pressure container, which is called a spinning pack and is composed of a polymer filtering portion and pores is used.

Such a spinning pack is exchanged as a unit component when the number of filaments, the cross-sectional shape, the thickness, etc. are changed, and is generally several tens to several hundreds kgf.
Used at high pressure such as / cm ² G.

Therefore, when assembling the spin pack, the polymer inside does not leak even under high pressure.
It is necessary to tighten each part firmly. Generally, a small spinning pack is manually tightened by using a torque wrench, but a large spinning pack having a tightening torque of more than 500 kg · m is assembled and disassembled by an assembling and disassembling device using hydraulic pressure. .

Such a spinning pack assembling / disassembling apparatus generally comprises a driver for tightening the spinning pack, and a fixing base for moving between the assembling / disassembling position and the fixing position of the spinning pack and fixing the spinning pack at the fixing position. Is equipped with.

For example, as a fixing stand for a cylindrical spinning pack in which a rotation preventing flat surface parallel to the outer peripheral surface of the bottom is formed,
As shown in FIG. 7, a base 51 provided with a handle 52 for movement.
8 is provided with a guide plate 53 that engages with the outer peripheral surface of the bottom of the spinning pack A including the rotation prevention flat surface b, or as shown in FIG.
By providing the guide plate 62 that engages with the outer peripheral portion a other than the above, the spinning pack is positioned and the spinning pack A is moved by manual force or hydraulic pressure, pneumatic pressure, etc. from a direction perpendicular to the rotation prevention plane b. There is one in which the spinning pack A is fixed at a predetermined position on the base 61 by providing a fixing means 63 for sandwiching.

[0007]

By the way, in the fixing table 50 shown in FIG. 7, since the guide plate 53 which engages with the parallel rotation preventing plane b is fixedly installed, the spinning pack A is fixed to the fixing table 50. Spin pack A for easy attachment and detachment
The distance between the guide plates 53 engaged with the rotation prevention flat surface b is 1 to 2 mm from the actual distance between the rotation prevention flat surfaces b.
Need to set longer.

However, the tightening torque of the driver is 60
If it exceeds about 0 kgm, the edge portion of the rotation prevention flat surface b pushes the guide plate to bite into when the spinning pack is tightened or disassembled due to the existence of the above-mentioned clearance of 1 to 2 mm, which makes it difficult to remove the spinning pack A. There's a problem.

Further, since the fixing table 60 shown in FIG. 8 itself becomes bulky, it has a drawback that the entire assembly and disassembly device becomes large and the operability is poor, and further, the spinning pack A is tightened with a large torque. Is the fixing means 63
There is a drawback that it is necessary to firmly make the spinning pack and a large force is required to fix the spinning pack A.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a fixing stand for a spinning pack which can easily fix and release the spinning pack with a small force, has good operability, and can be downsized. It is in.

[0011]

In order to solve the above problems, the present invention provides a spinning pack fixing base that moves between a spinning pack assembling / disassembling position and a spinning pack assembling / disassembling device. A guide frame that engages with the outer peripheral surface of the spin pack to position the spin pack,
Fixing means for fixing the spinning pack by abutting on a parallel rotation preventing flat surface formed on the peripheral surface of the spinning pack,
The fixing means comprises a pair of fixing members each having a guide surface provided corresponding to a plane for preventing rotation of the spinning pack, and a pair of taper guides slidably supported by the fixing members along the guide surfaces. And each taper guide has a parallel abutment surface that abuts against the rotation preventing flat surface of the spinning pack, and is in sliding contact with the guide surface of the guide frame on the opposite side of the abutment surface, and The present invention provides a fixed base for a spinning pack having a sliding contact surface inclined with respect to the contact surface.

Further, if one end of each of the tapered guides is connected to the operating member so as to be movable in the direction orthogonal to the contact surface, the operability is improved.

[0013]

In the spinning pack fixing base configured as described above, the spinning pack is installed on the base so as to engage with the guide frame at the assembling and disassembling position of the spinning pack in the assembling and disassembling apparatus, and then the fixing means. When the taper guide of is slid along the guide surface of the fixed member, the contact surface of the taper guide approaches while keeping the parallel state, and comes into contact with the rotation prevention flat surface of the spinning pack, and the spinning pack is placed on the base. Since the spinning pack is fixed at a predetermined position, a large force is not required to fix the spinning pack, and the spinning pack does not shift during tightening and the edge portion of the rotation prevention plane does not bite into the guide plate or the like.

Further, in the case where the end portions of the taper guides are connected by the operating member, the operation member allows the movement of the fixing base itself and the sliding of the taper guide, that is, both the fixing and the releasing of the spinning pack. To do.

As shown in FIG. 5, which is a detailed view of the portion A in FIG. 3, the taper guide 16 has a sliding contact surface 16a which is in sliding contact with the guide surface 15a of the fixing member 15, and this sliding contact surface 16a.
a wedge shape having a contact surface 16b that is non-parallel to a and contacts the rotation prevention plane b of the spinning pack A, and the taper guide 16 extends laterally along the guide surface 15a of the fixing member 15. By sliding the contact surfaces 16b to each other, the contact surfaces 16b move toward and away from each other while maintaining the parallel state.

The taper guide 16 has a sliding contact surface 16a.
Slots 16c penetrating from the contact surface 16b to the contact surface 16b are formed at two locations in the longitudinal direction.

In this embodiment, the fixed base 10 is manually moved, but it may be hydraulically or pneumatically driven.

[0026]

As described above, according to the present invention, the means for fixing the spinning pack is composed of a pair of fixing members having guide surfaces provided corresponding to the rotation preventing plane of the spinning pack, and along the guide surfaces. A pair of taper guides slidably supported by a fixed member, and the abutment surface of the taper guides that come close to and separate from each other by the sliding of the taper guides are brought into contact with the rotation preventing flat surface of the spinning pack, thereby performing spinning. Since the pack is fixed, the edge portion of the rotation preventing flat surface of the spinning pack does not bite into the taper guide due to tightening or the like, and the spinning pack can be easily attached and detached.

Further, since the sliding direction of the guide plate and the approaching / separating direction of the contact surface are different, even when the spinning pack is tightened with a large torque, a large force is not required to fix the spinning pack, and the fixing means itself. Since it is smaller than the conventional one, the fixing base is not bulky and the spinning pack assembling / disassembling apparatus can be downsized. Further, in the case where the operation member is attached, the spinning pack is fixed and released at the same time as the movement of the fixing table, so that the operability is extremely good.
