Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a yarn tube insertion device in an automatic tube changer of a spinning machine.

There have been various types of the above-mentioned thread tube insertion devices, but the device according to the present invention is disclosed in Japanese Patent No. 214711 (Japanese Patent Publication No.
This is an improved version of the wood tube insertion device (No. 2174).

That is, the device according to the above patent No. 214711 is shown in Fig. 1B.
As shown in FIG. 1A, a packet 4 of a carrier 3 is dropped from a back hopper 2 containing a large number of yarn tubes 1 into another front hopper 5', which is integrated with this hopper 2, and is then fed into the back hopper 2 as shown in FIG. 1A. The falling yarn tube 1 is held in an inclined state between both side walls of the hopper 5', and a slit 7 through which the tip of the spindle 9 enters is provided in the bottom plate 6 on which the lower end of the inclined yarn tube is placed, and the front and rear hoppers are moved along the spindle row. let,
This allows the tip of the spindle to reach the front hopper 5'.
The lower end of the lowermost yarn tube 1a is plunged into the large hole 8, and as the hopper moves, the yarn tube 1a is brought into a vertical position, and the weight of the yarn tube 1a causes it to fall into the spindle 9. This is what I did.

Therefore, in the case of this conventional device, the fitting of the thread tube onto the spindle is due to the natural fall of the thread tube itself due to its own weight, so it is difficult to allow the thread tube to reach the tip of the spindle, which has been conventionally used in similar devices. It is a device with a much simpler mechanism than the device that did all of this mechanically, and when comparing the two in actual use, the time required to insert and insert the thread tube is that the spinning machine has 200 spindles per side and the latter is much simpler. The former mechanical device required 180 to 200 seconds, whereas the former device using the yarn tube's own weight took about 60 to 70 seconds, which was approximately 1/3 of the time.

However, the former device still has the following drawbacks:
Due to this drawback, even the pipe changing speed is 60% as mentioned above.
~70 seconds was the maximum.

In other words, in the case of this device, since the insertion of the yarn tube into the spindle is ultimately due to the weight of the lowest yarn tube itself, the inclined shape is designed so that this weight acts normally directly above or near the spindle. It is necessary to ensure vertical transition of the lowest thread tube.

For this reason, it is extremely important to set the timing of the lowermost thread tube when it comes to rest, the speed of movement of the hopper corresponding to the rest position, and the timing of the tip of the spindle entering and locking into the large hole of the thread tube to be appropriate. If it is inaccurate, not only will the thread tube not be inserted smoothly (the spindle or thread tube may break or bend).

Therefore, in order to prevent this, it is necessary to always ensure that the tip of the spindle enters and locks into the large hole of the yarn tube so that the vertical transition of the lowest yarn tube that is sequentially dropped and fed is performed for each spindle. Therefore, it was inevitable that the transfer speed of the hopper would be limited to some extent.

That is, if the moving speed of the hopper is faster than the time from when the lower part of the yarn tube is locked to the tip of the spindle until it is dropped and inserted into the spindle, the yarn tube etc. will be damaged as described above.

In view of the above-mentioned drawbacks of the conventional ones, the present invention has been developed to improve and eliminate them, and to change the hopper by speeding up the transfer speed of the hopper and changing the tube based on a simplified mechanism without causing damage to the yarn tube, spindle, etc. It is an object of the present invention to provide a device that can perform pipe changes efficiently and without mistakes, and facilitates reliable and quick pipe changes, which is desired as an automatic pipe change machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below based on embodiments shown in the drawings.

The back hopper 2 has the same structure as the conventional example, as shown in FIG. 1B.

As shown in FIG. 2, the front hopper 5 has a cylinder box-like form that is almost the same as the conventional one, but it has three new guides for guiding the yarn tube 1 supplied from the back hopper 2 to the discharge port 10. Plates 11, 12 and 13 are provided.

The first guide plate 11 is arranged so that a thread tube discharge gap 15 is provided between the distal end edge of the first guide plate 11 and the side edge of the discharge port side wall 14.
and its base is attached to the other side wall 14'.

This guide plate 11 is connected to the lowest yarn tube 1 in the front yarn tube 5.
It is formed into a curved plate and is provided as the lowest guiding plate.

The second guiding plate 12 has its proximal end fixed to the outer surface of the other side wall of the front hopper which forms the yarn tube discharge gap 15 between it and the distal edge of the first guiding plate 11. 15 and protrudes upward.

Further, the third guide plate 13 is attached to the inner surface of the end wall 16 forming the upper front edge of the yarn tube outlet 10 in a pasted manner.

Then, the yarn tubes 1 supplied from the back hopper 2 into the hopper 5 from the upper receiving port of the front hopper 5 are sequentially dropped and stored in a line in an inclined manner with the lower end large hole 8 facing downward. As shown in FIG. The next upper yarn tube 1b is made to closely contact and overlap the lowest yarn tube 1a over its entire length.

Note that the lowermost yarn tube 1a supported by the first guide plate 11 tends to jump out laterally toward the yarn tube release gap 15 due to its own weight and the weight of the upper yarn tube 1b stacked on top of it. Form into a curved plate like this.

The second guide plate 12
This prevents a from jumping out of the hopper 5.

In this way, the yarn tubes supplied successively to the lowest yarn tube 1a and its upper yarn tube 1b, for example, as shown in the drawing, the three yarn tubes l c , 1 d, and 1e are integrated into one body and stacked diagonally. The lowermost yarn tube 1C and the previous yarn tube 1b are housed in such a manner that a gap 17 is created between them.

The third guiding plate 13 is for this purpose, and among the plurality of yarn tubes, at least the lower two yarn tubes 1c.

The third guide plate is moved so that the heads of the yarn tubes 1d are aligned and in contact with the third guide plate 13, and the lower ends of all the thread tubes 1c, 1d, le are in contact with the opposite side wall 16' and stand still in an inclined manner. For installation 13, set the height, plate thickness, size, etc.

As described above, the pipes in the front hopper 5 are being replaced.
A predetermined number of multiple yarn tubes are always accommodated by the feeding path and discharge of the yarn tubes, and each yarn tube is stacked with a gap in the middle by the first, second, and third guiding plates. Take a tilted posture.

At the time of tube change, the front hopper 5 accommodates a plurality of yarn tubes 1 as described above, and moves them along with the back hopper 2 from one end of the spindle row to the other end as in the past.

With this hopper transfer, as shown in FIG. 3, the tip of the spindle 9, which has entered the slit 7 of the hopper bottom plate 6, enters the lower end large hole 8 of the lowest yarn tube 1a and locks on the rim of the lower end of the hole 8. push it outside.

The lowermost thread tube 1a becomes slightly upright due to the extrusion of the spindle 9, and the head is pushed up accordingly, as shown in the figure (the heads of each thread tube come into close contact with each other at the same time, and the second and third from the bottom The gap 17 formed between the yarn tubes 1b, Ic disappears, and the plurality of yarn tubes 1b, Ic, Id, and 1e from the lowest yarn tube 1a to the uppermost yarn tubes are all closely stacked over the entire length.

As a result, the total weight of the upper multiple thread tubes is reduced to the lowest thread tube 1a.
The yarn tube 1a is pushed out along the curved surface of the first guiding plate 11 supporting it, and tilts toward the discharge gap 15, and as shown in FIG. It passes through the gap 15 away from the restraint, becomes almost vertical on the spindle 9 that is locked in the large hole 8, falls under its own weight, and is inserted into the spindle 9.

Since the lowermost yarn tube 1a receives the entire weight of the upper yarn tube, it is pushed out positively and vigorously, and with the addition of the horizontal and vertical transitions, its vertical transition is quickly carried out.

In this way, the lowest yarn tube 1a is inserted into the spindle 9, but in the meantime, a new yarn tube is supplied from the back hopper to the front hopper, and when the hopper moves to the next spindle, the stored yarn The same number of tubes are placed in the stacked position, and the lowest thread tube is inserted in the same manner as before.
This is repeated for each spindle during the hopper transfer, and the thread tube insertion of the spindle on one side of the machine is completed.

As explained above, in the present invention, the yarn tubes that are dropped and supplied from the back hopper for yarn tube storage to the front hopper, which is integrated with the yarn tubes, are held in an inclined state between the both side walls of the front hopper, and the yarn tubes are held in an inclined state between the both side walls of the front hopper, and are fed along the spindle rows of the hopper. In an automatic pipe changer for a spinning machine, the lowermost inclined thread pipe is locked with the spindle to bring it into a multiplier state, and the thread pipe is dropped and inserted into the spindle by its own weight. The system guides the inside of the hopper so that the multiple yarn tubes that are sequentially dropped and fed are piled up simultaneously on the lowest yarn tube that is moving vertically, so that when the lowest yarn tube is discharged, the upper yarn tubes are Since the entire weight is applied to the lowest yarn tube, the vertical movement of the yarn tube is actively and quickly carried out, and the yarn tube insertion is performed in a much shorter time than in the conventional case where only the dead weight of the lowest yarn tube is utilized. In addition, since the falling supply system tube is always maintained in a normal position by each guide plate, it is impossible for the spindle to enter the large hole of the yarn tube (this is done reliably and increases the efficiency of insertion of the yarn tube into the spindle). can.

Since the present invention makes use of the dead weight of the yarn tube, the structure is not mechanically complicated, and maintenance and maintenance are not troublesome, and the functions of the automatic tube changer are greatly improved.
