Description: TECHNICAL FIELD The present invention relates to a synthetic fiber spinning device, and more specifically, to a spinning block having a polymer introduction hole on its side from above the spinning device. The present invention relates to a novel spinning device having a mechanism for protecting and packing a packing provided alongside a polymer introduction hole of a spinning pack.

[Conventional technology]

Generally, a melt spinning apparatus for spinning synthetic fibers distributes a melter for extruding a raw material and a polymer extruded from the melter to a metering pump, and the polymer metered by the metering pump is spun through a polymer channel into a spinning pack. It is composed of a polymer feeding means to be introduced, a spinning block consisting of a heating box for housing and heating these polymer feeding means, and a spinneret pack to be attached to this spinning block,
In particular, when mounting the spinning pack on the spinning block, a structure which is made from above the spinning block is described in, for example, Japanese Patent Publication No. 47-
It has been widely used in the past, as disclosed in Japanese Patent No. 17727 and Japanese Patent Publication No. 51-22966. Furthermore, the spin pack is
In general, the polymer delivery hole provided in the spinning block and the polymer introduction hole provided in the spinning pack are mounted by being pressure-bonded and sealed through a seal packing, but particularly in a direction orthogonal to the spinning pack mounting direction. In a spinning block configured such that a spinning pack having a polymer introducing hole on the side surface of the spinning pack is mounted, the seal packing is previously fitted into the polymer introducing hole of the spinning pack at the time of mounting the spinning pack, The packing is inserted into the spinning block mainly by hand, and at the time of the insertion, the spinning pack is artificially polymerized in order to prevent the packing inserted into the polymer introduction hole from being removed or displaced. Is biased in the opposite direction to the direction in which the Had been allowed to insert pays attention. Furthermore, in mounting the spin pack, generally, the spin pack is heated in advance to a temperature slightly higher than the spinning temperature with a heater or the like, taken out from the heater immediately before use, and mounted in a predetermined spinning device. There is. However, this mounting operation is required to be quick because the temperature of the heated spinning pack is lowered unless the spinning is started at the same time as the end of the mounting or within a short time as much as possible, which causes trouble.

[Problems to be solved by the invention]

However, in the conventional method relying on the artificial consideration means as described above, since the above-mentioned quickness is required, it depends on the physical condition and skill of the operator, and in some cases, the packing is damaged or detached. , There is a risk of causing trouble such as misalignment. Therefore, there is a need for a means for protecting the packing that can be quickly and surely installed without giving due consideration to human attention.

Particularly, when a spinning pack having a polymer introduction hole on the side of the spinning pack in a direction orthogonal to the spinning pack insertion / extraction direction is mounted, the packing attached to the polymer introduction hole is prevented from being detached, displaced, or damaged. However, the packing can be quickly and surely inserted to a predetermined position without damaging the packing, and at the predetermined position, the packing can be pressed from a side corresponding to the polymer introducing hole with a sufficient pressing force. In addition, it is necessary to have a protection means for the polymer introduction hole packing when the spinning pack is attached, which does not cause any obstacle when the spinning pack is discharged.

In addition, recently, with the diversification of market needs, in terms of product type and quantity, the tendency of small-quantity and multi-product types has become stronger, and special yarns with special properties, such as mixed yarns of different polymers, or It is currently being used for composite threads. Therefore, at the production site that responds to these changes in market needs, the frequency of changing the type of product and the frequency of changing the polymers used tend to increase, and as a result, the frequency of changing the spinning pack also tends to increase.

Furthermore, in recent years, the so-called multi-thread formation in which a large number of yarns are spun and taken out from one spinning pack, and the composite spinning in which the yarns are formed from a plurality of components have been implemented, and the spinning to be used The size of the pack becomes larger or longer, and the weight of this larger or longer spinning pack becomes considerably heavy and it becomes necessary to mount it by using some kind of assisting means or mechanical mounting means. Is coming.

In such a situation, in order to satisfactorily mount the spinning pack using the assisting means or the mechanical mounting means, the packing attached to the polymer introducing hole of the spinning pack should be placed in a predetermined position while protecting it. It is a particularly important point to insert it and make sure that it is pressed with a sufficient sealing force.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art and to provide a novel spinning device provided with a means for protecting a packing attached to a polymer introduction hole of the spinning pack when mounting the spinning pack from above the spinning device. It is something to do.
