Description

Detailed Description of the Invention {Industrial Field of Application} The present invention relates to a synthetic fiber melt-spinning device, and more specifically, when a spinning pack having polymer introduction holes on the side is attached to a spinning block. A spinning pack mounting body is provided with a mechanism for attaching the spinning pack while protecting the polymer introduction hole packing, and also enables easy disassembly and cleaning of all channels from the melter to the spinning pack, which can be freely attached to and detached from the heating box. The present invention relates to a melt spinning device that is housed in a machine and can handle a wide range of spinning from single-component to multi-component spinning.

{Prior Art} Generally, a spinning device for spinning synthetic fibers,
For example, in a chip melt spinning device, there is a melter that melts and extrudes raw material chips, a polymer pipe that distributes the polymer extruded from the melter to a metering pump, a pump block that attaches the metering pump, and a pump block that attaches the metering pump to the polymer metered by the metering pump. The spinning block consists of a polymer conduit that leads to the spinning pack, and a heating box that houses and heats these.In particular, the items stored in the heating box are enclosed in a heating medium storage box inside the box. It is directly or indirectly heated by the heating liquid of the heated liquid heating medium or the vapor of the heated heating medium.

By the way, recently, with the diversification of market needs,
In terms of variety and quantity, there is an increasing trend toward high-mix production in small quantities, and the current situation is that special yarns with special properties, such as mixed yarns of different polymers or composite yarns, are being produced. Therefore, at production sites that respond to these changes in market needs,
The frequency of switching the product type and the frequency of switching the polymer used increases, and depending on the polymer used, unless the polymer flow path is completely cleaned, it may have a negative effect on yarn reeling performance and quality.

However, in the conventional spinning block, in particular, the polymer flow path component that receives the polymer from the melter and leads to the spinning pack is constructed integrally with the heating box, or alternatively, the component Even if all or part of the flow path can be disassembled, cleaning of the flow path is difficult because the parts are locked across multiple parts and disassembling and reassembling them on the machine is complicated. The main method used has been to flush out a switching polymer or an alternative polymer for a long time and clean the flow path with the polymer.

{Problems to be Solved by the Invention} However, as described above, it takes a considerable amount of time to completely clean the flow path using this method, so a decrease in operational efficiency is unavoidable.

Furthermore, the structure in which the spinning pack is attached to the heat medium-filled heating box from above or below the heating box is, for example,
−27772 Publication, Special Publication No. 17727, Special Publication No. 17727, Special Publication No. 17727
-17129, etc., and has been widely adopted.

However, in recent years, so-called multi-filament processing, in which many yarns are spun and taken from one spinning pack, has been implemented, and the spinning packs used have become larger or longer. As for the pack, it is no longer possible to attach it to the heating box manually, and it has become impossible to attach it by some mechanical means.

In addition, multi-component composite spinning packs for forming threads with multi-component polymers, for example, Japanese Patent Publication No. 44-22526
In the case of the spinning pack disclosed in the above publication, the height of the pack is inevitably high, and similar to the above, it is necessary to rely on some kind of mechanical means.

Furthermore, considering the social trend of people working in industry getting older, and the work environment for replacing spinning packs, it is important to note that even if spinning packs can be handled manually, mechanical It is expected that dependence on means will increase.

Furthermore, when installing the spinning pack,
Generally, the spinning pack is heated in advance with a heater or the like to a temperature slightly higher than the spinning temperature, and immediately before use, it is taken out from the heater or the like and placed in a predetermined spinning device.

However, this installation operation is performed at the same time as the installation is completed.
Alternatively, if spinning is not started within as short a time as possible, the temperature of the heated spinning pack will drop,
Promptness is required as this can cause problems.

Under these circumstances, in order to satisfactorily attach the spinning pack using mechanical means, it is necessary to insert the packing attached to the polymer introduction hole of the spinning pack into the specified position while protecting it, and to make sure that it is fully inserted. The important point is to ensure that the seal is pressed with a sufficient sealing force.

In particular, when installing a spinning pack having a polymer introduction hole on the side surface of the spinning pack in a direction perpendicular to the direction of insertion and ejection of the spinning pack, the packing attached to the polymer introduction hole is prevented from detaching, shifting, or being damaged. The gasket can be quickly and reliably inserted into a predetermined position without causing any damage to the gasket, and the gasket can be pressed with sufficient pressure from the side corresponding to the polymer introduction hole at the predetermined position. What is needed is a means for protecting the polymer introduction hole packing when the spinning pack is attached, and which does not cause any obstruction when the spinning pack is discharged.

Furthermore, in a spinning pack that can be handled manually, especially when installing a spinning pack having the polymer introduction hole on the side, it has conventionally been done manually, and the above-mentioned removal of the polymer introduction hole pack,
In order to avoid misalignment, the spinning pack is artificially shifted in the direction opposite to the direction in which the polymer is introduced, and the introduction hole pack is inserted with great care so as not to come into contact with the spinning device. I was being forced to do it. However, in the conventional method that relies on such human considerations, since the above-mentioned speed is required, it depends on the physical condition and skill of the operator, and in some cases, the above-mentioned gasket may be damaged or detached. , there is a risk of problems such as misalignment. Therefore, there is a need for a protection means for the above-mentioned gasket that can be installed quickly and reliably without requiring careful human consideration even when the device is installed manually.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to provide protection means for the packing attached to the polymer introduction hole of the spinning pack when the spinning pack is installed from below, and to provide protection for the packing from the melter to the spinning pack. It is an object of the present invention to provide a new melt spinning device that enables disassembly and cleaning of all channels and can also handle a wide range of spinning from single-component spinning to multi-component spinning.

{Means and actions for solving the problems} A melt spinning apparatus according to the present invention for achieving the above object has the following configuration. That is, (a) a heating box having an opening on the lower surface and a space connected to the opening formed inside; and (b) a heating box mounted adjacent to the inner wall of the heating box in the heating box space. , a spinning pack mounting body having a recessed part on the lower surface and a molten polymer outlet hole opened in the side wall surface of the recessed part; (c) detachably mounted in the recessed part of the spinning pack mounting body from below; and when the spinning pack is installed in a predetermined position of the recess of the spinning pack mounting body,

These matters will be explained in more detail using FIG. 10.

FIG. 10 is a diagram illustrating an embodiment of a channel configuration and polymer distribution configured to introduce a plurality of polymers into each of a plurality of spinning packs using three melters; Shows the direction of polymer flow.

That is, in FIG. 10, polymers derived from melters 6a, 6b, and 6c that melt and extrude raw material chips flow through channels 7a, 7b, and 7c, respectively, and reach branch points 33, 33', 49, 49', 50, 50', the metering pumps 11a, 11b, 11c,
11a', 11b', and 11c', and are measured by these metering pumps, and then introduced into the spinning packs 16, 16a, 16b, and 16c through the outlet hole 20 bored in the spinning pack mounting body 10. The flow path is configured as required.

Can be used for yarn spinning.

In addition, in FIG. 10, one metering pump is provided with two metering pumps, but the pump is not necessarily limited to this type of pump, and one metering pump is one metering pump, or one pump is four metering pumps.

a, 26b and hole 4 for inserting the spinning pack suspension device.
6a and 46b are provided with the same structure as the spinning pack mounting body 10 shown in FIG. 3 above.

Furthermore, even in this divided spinning pack attachment body, there is a flow path leading to the metering pump, and the polymer discharged from the metering pump is transferred to the spinning pack, similar to what is shown in FIGS. 3 and 4. It is also formed with the above-mentioned configurations such as guiding channels and guide blocks.

Since the split-type spinning pack mounting body configured in this manner can be washed in sections, there are additional effects such as the need for a relatively small washing tank.

The width W ₄ between the left and right protrusions is narrower than the width W ₅ of the main body of the spinning pack 16, so that it does not cause any obstruction when the spinning block is inserted.

Furthermore, the width W ₃ of the protrusion shown in FIG. 14 is
It is formed to match the slit 22 formed in the guide block 21 which is inserted and locked into the groove 38 on the lower surface of the spinning pack mounting body 10.

Furthermore, a hole 4 is provided in the spinning pack head 51.

Next, the spinning pack 1 constructed in this way is
6 to the spinning pack mounting body 10 will be explained with reference to FIGS. 15 and 16.

FIG. 15 shows that the spinning pack is inserted into the spinning pack mounting body 10 constituting the spinning block according to the present invention while protecting the packing provided in the polymer introduction hole of the spinning pack, and is locked in a predetermined position. Fig. 16 is a diagram of the state in which the spinning pack is installed.
It is a sectional view taken along the line QQ in the figure.

In FIGS. 15 and 16, the spinning pack 16 is first input into a spinning pack storage space 45 formed on the lower surface of the heating medium storage box 2 in the direction of the arrow from below, and is inserted into the spinning pack 16 or into a machine (for example, It is inserted using the device shown in Japanese Patent Publication No. 42-9490). Then, the protrusions 39, 39' provided at the upper end of the spinning pack head 51 are inserted into the grooves 38 on the lower surface of the spinning pack mounting body 10 and are locked into the slits 2 of the guide blocks 21, 21a.
2, 22a. At this point, as described above, the guide blocks 21 and 21a are positioned so as to maintain a certain gap between the polymer introduction hole packing of the spinning pack and the opposing wall surface of the spinning pack mounting body, so that the spinning Pack 16
A gap e is maintained between the packing 40 provided in the polymer introduction hole and the wall surface of the spinning pack mounting body 10 in which the polymer outlet hole 20 is formed, and the spinning The head 51 of the spinning pack 16 is guided to bring it to the end of the slit, that is, to a predetermined position for attaching the spinning pack.

Next, the above-described spinning pack suspension device 23 is inserted through the hole 25 provided in the spinning pack mounting body 10 into the hole 41 provided in the above-described spinning pack head into which the above-described suspension device 23 is inserted. The pack is suspended.

Next, the push bolt 24, which had been previously screwed into the threaded hole 26 of the spinning pack mounting body 10 and was waiting without protruding into the groove 38 of the spinning pack mounting body, is further screwed in using input or power to attach the spinning pack. 16 to press the packing 40 provided in the polymer introduction hole of the spinning pack against the wall surface 47 in which the polymer introduction hole 20 is provided with a predetermined pressing force.

Note that the wall surface side of the slit 22 facing the polymer outlet hole 20 of the spinning pack attached body is widened upward at its tip, and the width W ₂ near the top end is wider than that. Since the width is greater than the sum of the lower width W ₁ and at least the sum of the above-mentioned gap e and the collapsing allowance due to the pressure of the packing of the polymer introduction hole,
The spinning pack can be moved toward the wall surface of the spinning pack mounting body where the polymer outlet hole 20 is provided by an amount necessary and sufficient to press the polymer introduction hole packing 40 of the spinning pack.

Furthermore, as described above, since the tip of the spinning pack head 51 is tapered and the lower end of the slit 22 is formed to widen downward, the spinning pack can be stored in a heating medium. At the initial stage of inserting the spinning pack into the spinning pack storage space 45 of the box 2, even if the protrusion provided at the upper end of the spinning pack head and the slit that meets the protrusion are misaligned, the spinning pack head 51 is The inclined surface conforms to the slit 22 to control the attitude of the spinning pack 16 and easily spin the spinning pack 1.
6 can be fitted into the slit 22.

In addition, when removing the spinning pack, the lower part of the spinning pack is supported in advance (for example, using the device shown in Japanese Patent Publication No. 42-9490 mentioned above), and the push bolt 24 is inserted before the spinning pack is inserted. When the spinning pack is loosened to the previous state, the spinning pack suspension device 23 is removed, and the support at the bottom of the spinning pack is lowered, the spinning pack is caused by its own weight to cause the protrusion 39 at the upper end of the spinning pack to move to the upper end of the slit 22. It is possible to descend along the slit while sliding on the nearby slope 36 and remove the spinning pack using its own weight.

In addition, in this embodiment, the spinning pack is not only pressed and locked with the push bolt, but also suspended using the suspension device 23, which is a more preferable embodiment in terms of preventing the spinning pack from falling.

It is possible to freely select whether or not to use this suspension device, and if the suspension device is not used, it is sufficient to support the spinning pack at all times until the spinning pack attaching/detaching operation is completed.

By using the above-mentioned packing protection means, a) when inserting the spinning pack, the packing provided in the polymer introduction hole of the spinning pack does not come into contact with any part of the spinning pack mounting body until it reaches a predetermined position for installing the spinning pack, and b At a predetermined position where the polymer introduction hole provided in the spinning pack matches the polymer outlet hole provided on the wall of the groove on the lower surface of the spinning pack mounting body, the packing provided in the polymer introduction hole of the spinning pack can be press-sealed. (c) When the spinning pack is inserted, it is guided so that the polymer introduction hole of the spinning pack is easily aligned with the polymer outlet hole on the wall surface of the spinning pack attachment body, and (d) A concave groove on the lower surface of the spinning pack attachment body is formed. The guide member on the wall side where the polymer outlet hole is provided does not allow the polymer that would flow down (drip down) from the polymer outlet hole to come into contact with it, and when removing the spinning pack, it is easily removed by gravity. Since the spinning pack has a removable shape, the packing provided in the polymer introduction hole of the spinning pack can be installed in a predetermined position accurately and quickly without being damaged, misaligned, or detached. Therefore, the spinning pack can be easily, quickly and safely installed in a predetermined position using mechanical or manual force, and the spinning pack can also be easily removed.

When a suspension device is used as in this embodiment, as described above, the spinning pack is already suspended from the suspension device when the push bolt is operated, so there is no need to support the spinning pack. Furthermore, if the suspension device and the polymer introduction hole of the spinning pack are precisely positioned with respect to the polymer outlet hole provided on the wall of the concave groove on the lower surface of the spinning pack mounting body, the push bolt can be operated. Therefore, the head of the spinning pack can slide along the suspension device and smoothly move to the wall surface of the groove, and the head of the spinning pack can slide along the suspension device and smoothly move to the wall surface of the groove, and the polymer introduction hole provided in the spinning pack can be connected to the wall surface of the spinning pack mounting body. The position can be easily and safely aligned with the polymer lead-out hole provided in the.

The above-mentioned suspension device may have any form as long as it has the following functions. That is, A. The spinning pack can be suspended, B. The spinning pack can be smoothly moved along the suspension tool, C. The spinning pack can be quickly attached and detached, and D. In the state where the spinning pack is suspended, The positions of the polymer introduction hole provided in the spinning pack and the polymer lead-out hole provided in the wall surface of the concave groove on the lower surface of the spinning pack mounting body are aligned, and the polymer flows down (drops down) from the polymer lead-out hole. The suspension device must be installed in a position where it will not touch any polymer (for example, above the polymer outlet hole).

Furthermore, the above-mentioned function allows the spinning pack to be suspended in a predetermined position while protecting the packing provided in the polymer introduction hole of the spinning pack, or to be easily removed using gravity, and
