Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reeling tank in a direct reeling machine, and its object is to separate the pupae that have fallen into the reeling water during reeling from the thin-skinned cocoons and take them out.

In a direct reeling machine, new cocoons are put into the reeling tank, and while the new cocoons are boiled, grains are added to the cocoons one by one from the boiled cocoons, and thin-skinned cocoons or part of the pupae that cannot be reeled are removed. What is floating in the reeling bath is drained out from the reeling tank, but the pupae or pupa sink to the bottom of the tank, so a scooping net is used to collect them. However, this posed a problem in terms of work efficiency as it was necessary to find and contain the pupae scattered over a wide area of the reeling tank one by one.

The device of the present invention has been developed in view of this point.
The pupae that have fallen to the bottom of the reeling tank during reeling are separated from the thin-skinned cocoons and concentrated in one place outside the reeling tank, where they can be taken out.

Next, an example of implementation of the device of the present invention will be described with reference to the drawings.

5, a plurality of support arms 48 extend radially, and a cord member 50 is suspended from the tips thereof. The cord member 50 is constructed by attaching a plurality of cord brooms 53 downward to a cord broom base 52 provided at the lower end of a cord rod 51, and the cord rod 51 is attached to a support arm 48 by a pin 54. It hangs down so that it can swing freely. A guide bar 56 of the cord member 50 is supported by a support 55 fixed to the peripheral wall 11 of the reeling tank 1. The guide bar 56 is located at the upper part of the reeling tank 1 and is connected to the cord rod 5 hanging down inside the reeling tank 1.
1, the cord broom 53 at the tip of the cord rod 51 is brought close to the cocoon thread 71 pulled out from the cocoon 70 being reeled to perform a pinning operation.
It is provided in an arc shape over approximately half the circumference of the support arm 48, and the radius of the arc is smaller than the length of the support arm 48.

The thread threading tube 60 is inserted into the hollow shaft 43 of the strapping device 40. The thread passing tube 60 is suspended from the tip of a swinging arm 62 that is swingably supported by a support arm 61 fixed to the frame 41 . The other end of the swinging arm 62 is pivotally supported by a connecting rod 65 that is pivotally connected to a pulley 64 that is integral with the motor shaft of a motor 63 supported by the frame 41, and as the motor 63 rotates, the threading tube 60 vibrates up and down. do.

Next, the operation of the device of the present invention will be explained.

In the device of the present invention, the reeling water is circulated between the reeling tank 1 and the pupae collecting tank 30 by the pump 21, and when the amount of hot water decreases, water is poured into the pupae collecting tank 30 from the water tap 34. ing. The reeling water in the pupa collection tank 30 is heated to a predetermined temperature by a heating tube 31. The pump 21 constantly rotates, passes through the hollow rotating shaft 5 from the delivery side conduit 22, enters the reeling cocoon separator 17 from the top thereof, and flows out into the reeling tank 1 from the reeling bath outlet 18. At this time, the reeling bath outlet 18
Since the reeling water is opened at a position where the reeling water is spouted below the cocoon 72 which is floating on the surface of the reeling water during reeling or is capable of reeling, the reeling water flows out from the reeling water outlet 18 into the reeling tank. The reeling water hits the pupa 31, which is located slightly lower than the cocoon 70 being reeled, and
1 to the outer periphery of the reeling tank 1, and the pupa 31 advances along the peripheral wall 11 of the reeling tank 1 due to the stirring action of the cord broom accompanying the rotation of the cord member 50. At the same time, the cocoon 70 being reeled is also pushed toward the outer periphery of the tank, increasing the diameter of the circle formed by the grained cocoons at the center of the reeling tank. Furthermore, there is a reeling tank 1 and a pupa removal tank 2.
Since the lower edge 28 of the blocking plate 26 is located at a lower position than the cocoon 70 that is being reeled, the selective outlet 24 located at the border between The pupa 31 that is present flows into the pupa removal tank 2 together with the reeling water that flows out from the reeling tank 1 to the pupa removal tank 2, and further flows out from the pupa outflow port 23 to the pupa collection tank 30, and is collected in the pupa collection tank 30. are collected on the screen 32 of. The reeling water in the pupa collecting tank 30 is heated to a predetermined temperature by the heating pipe 33, and then reaches the pump 21 via the discharge side conduit 29 again and is circulated to the reeling tank 1.

Inside the reeling tank 1, the hollow rotating shaft 5 is rotated by the rotation of the pulley 20 which receives rotation from a prime mover (not shown).
is rotating, and the rotating bottom 8 is rotating slowly. At the same time, the rotation of the drive shaft 46 is transmitted to the bevel gears 47, 44, the hollow shaft 43, and the rotary disk 45, and the support arm 48 integrated with the rotary disk 45 circulates and rotates the cord member 50 within the reeling tank 1.

The cord member 50 rotates around a hollow shaft 43, and when it is in the half circumference of the reeling tank, the cord broom 53 is immersed in hot water and brought into contact with the floating reelable cocoons 72 to extract the cord. When the cord rod 51 comes into contact with the guide bar 56 as the support arm 48 rotates, the cord rod 5
1 is bent at an acute angle with respect to the support arm 48, and the rope broom 53
The cocoon thread that has been taken out is converged at the lower end of the thread threading tube 60 and attached to the cocoon thread 71 that is being hoisted up.
The string is attached to the cocoon thread 71.

The braided thread passes through the thread threading tube 60 and is wound up through a kennel device (not shown). The yarn threading tube 60 is swung up and down by a swiveling arm 62 that oscillates in response to the rotation of a motor 63, giving a minute impact to the cocoon 70 being reeled to help unravel it.

The cocoon that has been unwound and has become a pupa 31 is cocoon 7 during reeling.
It will be located below 1. Then, as described above, the particles pass through the pupa discharge tank 2 from the selective outlet 24, fall from the pupa outlet 23 into the screen 32 of the pupa collection tank 30, and are collected.

During the silk reeling, the cocoon and pupa 10, which are unwound to the pupa and are mainly composed of pupae, fall onto the rotating bottom 8. The rotating bottom 8 constantly rotates during reeling, and if the rotating bottom 8 has blades 9, it is further affected by the blades 9, and a water flow is also generated toward the peripheral wall of the reeling tank, so that water falls onto the rotating bottom 8. The pupa 10 reaches the outer periphery of the rotating bottom 8 as the rotating bottom 8 rotates, and the pupa 10 reaches the outer periphery of the rotating bottom 8 and the surrounding wall 11.
It falls to the bottom 6 of the reeling tank through the gap 12 between the yarn and the reeling tank. Since the tank bottom 6 is inclined toward the pupa removal tank 2 as shown, the pupae 10 sink to the deepest part according to the slope, pass through the gap 7 from the reeling tank 1, and gather at the bottom of the pupa removal tank 2. This pupa 10 is removed as appropriate.

As described above, the apparatus of the present invention has a silk reeling tank having a circular planar shape and a pupa removal tank adjacent to each other, and connects both tanks in series through a gap provided at the bottom of the peripheral wall of the silk reeling tank. The reeling tank is tilted toward the gap, and the rotary bottom is pivoted with a gap between the reeling tank circumferential wall and the rotary bottom. The pupae can be introduced onto the bottom of the tank and collected in one place on the bottom of the tank through a gap provided in the peripheral wall following the slope of the tank bottom, and the pupae can be easily taken out from that part. There is no need to soak the pupae in the reeling bath, which is effective in maintaining the reeling bath.
