The roller 321 is installed on the support frame 322 so as to be rotatable in the take-in direction of the take-up package. Therefore, the winding package carried into the lifter 1 with inertia by the conveying means C is stopped by the stopper 34 or the winding package carried in first without losing the inertia due to the rotation of many rollers 321. Until the roller 321 is reached. As a result, the work efficiency of carrying the winding package into the lifter 1 is improved.

Further, a roller R (see FIG. 5) may be provided on the inclined plate 311 between the opposing winding package holding means 32 in order to easily carry the winding package into the lifter 1. In this case, since the take-up package is held on the roller R, the take-up package holding means 32 does not necessarily hold the take-up package directly, and the take-up package does not come out of the take-up package holding unit 3. You can just do it. Therefore, in this case, the winding package holding means 32 may be provided at a position where both of the opposing winding package holding means 32 are not in contact with the winding package.

Thus, the distance between the winding package holding means 32 which opposes can be adjusted by adjusting the said fixed angle.

In FIG. 1, a stopper 34 is provided at the end of the take-up package holder main body 31 in the take-up package carry-in direction in order to prevent the carry-in take-up package from rolling off from the take-up package holder 3.

The stopper 34 may be fixed to the inclined plate 311 with screws, or may be installed so as to be removable. When the take-up package holding unit 32 is inclined when the stopper 34 is removed from the take-up package holding unit 3 after the rise of the take-up package holding unit 3 holding the take-up package, the take-up package holding means 32 is inclined. Will be carried out of the lifter 1 by its own weight. As a result, it is easy to carry out the take-up package.

From the above, it can be seen that the winding package is held in three directions by the pair of winding package holding means 32, the stopper 34, or another winding package in the winding package holding unit 3 (FIGS. 1, 2 and 3). (See FIG. 4). Therefore, the winding package holding unit 3 can reliably hold the winding package having an unstable shape such as a truncated cone.

FIG. 4 is a side view showing a state in which the winding package holding means 32 holds the winding package. The winding package holding means 32 holds the winding packages of various diameters by adjusting the fixing angle of the winding package holding means 32 to the inclined plate 311 and adjusting the distance between the winding package holding means 32. You will be able to do that.

Next, the raising / lowering part 4 is demonstrated using FIG. The elevating unit 4 includes an air cylinder 41, a sprocket 42 and a silent chain 43. The silent chain 43 is described in FIGS. 2, 3, 5, and 8.

A sprocket 42 (see FIG. 2) that meshes with the silent chain 43 is rotatably provided at the upper end of the piston rod 411 of the air cylinder 41.

The silent chain 43 is engaged with the sprocket 42, one end thereof is fixed to the lifter body 1 with a screw, and the other end is fixed to the winding package holding unit 3 with a screw. Therefore, when the sprocket 42 is lifted by the piston rod 411 of the air cylinder 41, the silent chain 43 is guided by the sprocket 42 and lifts the winding package holding part 3.

The mutual relationship among the lifter main body 2, the winding package holding unit 3, and the elevating unit 4 will be described with reference to FIGS.

The guide portion 22 (see FIGS. 1 and 3) of the lifter main body 2 that guides the take-up package holding portion 3 when ascending / descending is provided so that the take-up package holding portion 3 can be reliably guided in the vertical direction. Is provided in a vertical direction. As the guide part 22, a slit provided in the lifter body 2 may be used, or a vertical plate may be used. In the present embodiment, the guide portion 22 includes a slit 221 and a vertical plate 222.

A plurality of wheels 33 are installed in the take-up package holding unit 3 so as to be guided by the guide units 22 (221, 222) of the lifter body 2 when moving up and down. 1 and 3, the wheel 33 includes a central wheel 331 and left and right wheels 332. When moving up and down, the wheel 331 travels along the side wall of the slit 221, and the wheel 332 travels along the vertical plate 222. As a result, the stability of the take-up package holding unit 3 during elevation is improved.

The guide rail 23 of the lifter main body 2 that guides the lift unit 4 when moving up and down is installed in a direction perpendicular to the lifter main body 2. The guide rail 23 is fixed to the lifter body 2 with screws or the like.

The sprocket 42 of the elevating part 4 is engaged with the guide rail 23 via the silent chain 43 so that it is guided by the guide rail 23 of the lifter main body 2 when ascending and descending (see FIG. 3). As a result, the silent chain 43 is guided by the guide rail 23 with the guide rail 23 sandwiched between the left and right links of the silent chain 43, so that the sprocket 42 moves up and down along the guide rail 23 in the vertical direction. The stability of 42 is increased.

The relationship between the conveying means C and the lifter 1 will be described with reference to FIG. In the spinning machine S, a sensor S6 is installed at the end of the conveying means C. Therefore, if the sensor S6 detects the winding package while the winding package holding unit 3 is raised, it can be controlled to stop the conveying means C. As a result, a failure of carrying the take-up package into the lifter 1 when the take-up package holding unit 3 is raised does not occur.

As shown in the lower left of FIG. 1, which is a front view of the lifter 1, a fitting portion E that fits with a wheel M provided on the conveying means C side of the lifter 1 is provided at the end of the conveying means C on the lifter 1 side. The lifter 1 is fixed to the spinning machine S by fitting the wheel M into the fitting portion E from above. Therefore, the lifter 1 can be easily detached from the spinning machine S by removing the wheel M from the fitting portion E. The lifter 1 and the spinning machine S may be integrated by fixing with screws or the like.

The operation of the lifter 1 according to the present invention will be described with reference to FIG.

Since the first sensor 211 is installed in the lower part and the second sensor 212 is installed in the upper part of the lifter 1, when the take-up package is carried into the lifter 1, the first sensor 211 causes the take-up package to be installed. It detects and raises the winding package holding part 3 automatically. Then, by removing the winding package at the raised position, the lifting / lowering unit 4 is controlled so that the winding package holding unit 3 is automatically lowered when the second sensor 212 does not detect the winding package. The

As an example of the control method of the lifting unit 4, when a plurality of sensors 211, 212 are installed on the upper and lower parts of the lifter body as in this embodiment, all the sensors 211 on the lower side detect the winding package. Sometimes, the winding package holding unit 3 is raised, and when all the sensors 212 on the upper part do not detect the winding package, the winding package holding unit 3 is lowered. By controlling in this way, the lifter 1 can be operated efficiently.

Without using a detection means such as a sensor or a limit switch, visually check the position of the winding package and manually operate the lifting unit 4 to lift the winding package or lower the winding package holding unit 3 May be.

In the present embodiment, since the winding package holding unit 3 is lifted and lowered using the air cylinder 41 and the silent chain 43, the winding is carried by the double stroke mechanism by a distance twice the lifting distance of the sprocket 42. The package holding unit 3 can be raised and lowered.

Next, how the spinning machine S according to the present invention is specifically used will be described using examples.

In FIG. 6, the spun yarn S7 discharged from the spinning device S12 of the spinning machine S is sent downward by the yarn feeding device S13, and a clearer S15 that detects a yarn defect and performs yarn cutting to remove the yarn defect portion. After that, it is wound up by the winding device S14 to form a winding package P.

The formed winding package P is removed from the winding device S14 and falls on the conveyor C while being kept sideways. The conveyor C is moving from left to right in FIG.

Next, the function of the lifter 1 will be described with reference to FIGS. 1 and 2.

The take-up package P conveyed by the conveyor C is carried onto the lifter 1 installed at the end of the conveyer C onto the roller 321 of the take-up package holding means 32 by inertia due to the convey of the conveyer C.

The take-up package P carried on the roller 321 is formed by the take-up package P carried in first when the stopper 34 or the take-up package holding means 32 can hold two or more take-up packages. Be stopped. Since the inclined plate 311 and the take-up package holding means 32 are inclined downward with respect to the take-in direction of the take-up package P, it is easy to carry the take-up package P into the take-up package holding unit 3.

Since the lower both sides of the winding package P are held along the loading direction by the pair of winding package holding means 32 arranged in a direction parallel to the loading direction of the winding package P, there is no wobble. The winding package P is reliably held in the winding package holding unit 3.

When the winding package P is held by the winding package holding unit 3, the sensor 211 installed at the lower part of the lifter body 2 detects the winding package P, thereby operating the air cylinder 41, and The piston rod 411 is extended to push up the sprocket 42.

When the sprocket 42 is pushed up, the sprocket 42 is guided and raised while meshing with the guide rail 23 via the silent chain 43. Then, the silent chain 43 is guided by the sprocket 42 and the winding package holding unit 3 side is pushed up. As a result, the winding package holder 3 is lifted by the silent chain 43.

When the take-up package holding unit 3 is raised by the silent chain 43, the take-up package P held by the take-up package holding means 32 is also raised, for example, to the waist level of the operator. As a result, the operator can easily take out the take-up package P from the lifter 1 after the take-up package holding unit 3 is lifted.

When the take-up package P is lifted from the lifter 1 by the operator after the take-up package holding unit 3 is lifted, the sensor 212 installed on the upper part of the lifter body 2 detects the absence of the take-up package P. When the absence of the winding package P is detected, the piston rod 411 of the air cylinder 41 starts to descend.

As the piston rod 411 is lowered, the sprocket 42 is lowered, and the winding chain holding portion 3 supported by the silent chain 43 and the silent chain 43 is also lowered.

When the winding package holding part 3 reaches the lower end of the lifter body 2, the winding package P can be carried into the lifter 1 again, and the above lifting operation is repeated.

The object to which the lifter 1 is used is not limited to the spinning machine S, and the lifter 1 may be used for other textile machines.

From the above description, since the lifter is provided separately from the conveyance in the horizontal direction and thereby conveyed in the vertical direction, the textile machine can be saved in space. In addition, the vertical elevating speed can be independently controlled regardless of the horizontal conveying speed.

Further, even with a truncated cone-shaped winding package that is difficult to lift while being securely held, if the textile machine according to the present invention is used, it is lifted up to a waist level that makes it easy for an operator to work while holding it securely. be able to. As a result, the burden on the worker can be greatly reduced.

In addition, since the winding package is lifted and lowered while being securely held, if the textile machine according to the present invention is used, the winding package is not damaged at the time of lifting. Furthermore, if two or more take-up packages can be held by the take-up package holding unit, the conveyance in the vertical direction can be efficiently performed.
