Description

[Detailed Description of the Invention] Industrial Field of the Invention The present invention relates to a roving bobbin mounted on a bobbin peg,
The present invention relates to a device that is attached to and detached from a bobbin hanger in an upper position.

2. Description of the Related Art A detaching device as described above is used as a tube changing machine in a roving machine (Japanese Patent Laid-Open No. 62-57944) or a spinning machine for spinning creels (Japanese Patent Laid-open No. 62-5).
3425, JP-A-64-20335, etc.), and its basic structure is shown in FIG. In FIG. 6, when the roving bobbin (hereinafter, bobbin) B is attached to and detached from the bobbin hanger 10, the peg support 30 is raised along the guide rod 19 by the chain drive with the bobbin B placed on the bobbin peg 31. .
A heavy bobbin 11 of a known bobbin hanger 10 shown in FIG. 5 is pushed up by a bobbin top portion to push up an actuator 12, and a claw piece 14 is projected from the inside of the cylinder shaft 13 or is housed in the cylinder shaft 13. After that, the rising end limit switch LS fixed to the frame 18
And the signal generated by the engagement of the dog 51 of the peg support 30 lowers the peg support 30. Since the actuator 12 is biased downward, an axial force that opposes the biasing force is generated downwards when the claw piece 14 is projected and stored, and this force causes the bobbin peg 31 to bias upward. It is designed to descend a predetermined amount with respect to the bobbin support 30 against the spring force of the.

According to the above, the ascending end limit switch LS is attached to the frame 18
Since the up / down switching position of the peg support 30 is constantly constant from the floor surface because it is fixed to the bobbin hanger 10, the bobbin hanger 10 can be smoothly attached to and detached from the bobbin hanger 10 unless the height position of the bobbin hanger 10 is also the same from the floor surface. I can't. But Bobbin Hanga
A large number of 10 are suspended in the longitudinal direction, for example, for one roving frame or one spinning creel, for example. Therefore, making the heights of all of these bobbin hangers 10 the same from the floor surface is considerably troublesome work, and the height of the guide rail 6 of the carriage bar 5 may change due to long-term use. Therefore, the height of the bobbin hanger 10 is likely to vary, and there is a problem that, for example, when the bobbin hanger 10 is too high, an attachment / detachment error occurs.

Means for Solving the Problems The present invention is directed to a detector for detecting a predetermined amount of lowering of a bobbin peg in a case where a bobbin peg is lowered by a predetermined amount by an operation of attaching and detaching a roving bobbin on a bobbin peg to a bobbin hanger by lifting and lowering a peg support. Is provided on the peg support.

Action The attachment / detachment operation of the roving bobbin to / from the bobbin hanger, that is, the protrusion of the claw piece of the bobbin hanger and the lowering of the bobbin peg that moves due to the axial force during the storage switching operation are detected by the detector provided on the peg support, and this signal is used. Switch the up / down direction of the peg support to down. Since the switching operation of the claw pieces of the bobbin hanger is detected, the bobbin attaching / detaching operation is reliably performed even if the height position of the bobbin hanger varies.

Embodiments This invention will be described by applying it to the Shinasing machine 15 in the spinning creels. In FIG. 3, 1 is the front row of the creel,
2 is a creel rear row, 3 is a spare rail (the guide rail 6
4) is a bobbin carriage guided by the spare rail 3, and the above-mentioned known bobbin hanger 10 is mounted on the carriage bar 5 at a bobbin pitch in the longitudinal direction of the spinning creels. Shino exchange machine 15 is disclosed in JP-A-62-53425, and a pair of peg support pairs 29, 30 having a plurality of bobbin pegs 31 on the upper surface in the longitudinal direction at the bobbin pitch of a spinning creel are lifted, moved back and forth, and , Shino end exit nozzle 16 and Shinotsu head 17 connect the Shinbo of bobbin F to Shino of small bobbin S located in front row 1 of the creel, then take out small bobbin S and take full bobbin F of spare rail 3. The small bobbin S is suspended from the bobbin hanger 10 in the front row 1 of the creel after the small bobbin S is taken out.

FIG. 2 shows a lifting and lowering device for the peg support 30 for a full bobbin and a front and rear device. A lower part 20a of the lifting body is guided up and down by a guide rod 19 erected from the frame 18. The peg support 30 is connected to the tip ends of the pair of link levers 21 of the lifting body 20. The link lever 21 is connected to a swing motor 24 by a gear train 22 and a swing lever 23 in the lifting body 20, and the bobbin peg of the peg support 30 is operated by these operations.
31 moves between the position directly below the spare rail 3 and the position directly below the creel front row 1. A chain 26 wound between upper and lower sprockets 25 of the frame 18 is connected to the lower portion 20a of the lifting body 20, and the lifting motor 27 removes the lower end of the peg support 30 shown in FIG. 3 and the bobbin B from the spare rail 3. ,
Further, it is configured to be lifted and lowered with respect to a lifted position (which varies depending on the height position of the bobbin hanger 10).

Since each bobbin peg 31 of the peg support 30 has the same structure, only one of them will be shown. In FIG. 1, a bobbin peg 31 is vertically slidably inserted through a key 33 and a key groove 34 on a peg shaft 32 rotatably supported by a peg support 30. A spring 37 is interposed between the bobbin peg 31 and the flange member 36 sandwiched between the peg shaft 32 and the bearing 35, and urges the bobbin peg 31 upward.
A cap-shaped head 32a is provided to prevent the cap from coming off. The spring 3
In the state where the full bobbin F is placed on the flange portion 31a in addition to the self weight of the bobbin peg 31 and the self weight of the full bobbin F is applied, the bobbin peg 31 does not descend from the mounting position shown by the solid line in FIG. The spring force is set so as to be lowered by a predetermined amount L when a slight additional load is applied to the axial force at the time of projecting or retracting the claw pieces 14 of 10. A belt pulley 38 is key-connected to the lower end of the peg shaft 32. Belt pulley
38 is rotated by a rotation motor (not shown) via a belt 39, and after the full nozzle bobbin F on the bobbin peg 31 is succeeded by the full nozzle bobbin S by the outlet nozzle 16 and the continuous head 17, the small bobbin S is connected to the full bobbin F. The peg rotation structure is not an essential requirement of the present invention, although it is designed to send out and rewind.

A bracket 40 is attached to the peg support 30 so as to correspond to each bobbin peg 31, and a reflection type photoelectric switch (detector) 41 is provided at the tip of the bracket 40 and a lower collar of the bobbin B mounted on the flange portion 31a. It is fixed so as to face the portion 42. An annular reflecting plate 43 is integrally attached to the lower brim portion 42 of the bobbin B, and when the claw piece 14 of the bobbin hanger 10 is opened or closed, that is, when the bobbin peg 31 is lowered by the predetermined amount L, the photoelectric switch. The reflector 41 does not detect the reflector 43. All the contacts of each photoelectric switch 41 of the peg support 30 are connected in series, and when all the photoelectric switches 41 are turned off, the rotation direction of the elevating motor 27 is switched, and the elevating direction of the peg support 30 is changed from upward to downward. It is electrically connected so that it can be switched to.

Now, when the small bobbin S of the spinning creel is positioned in the front row 1 of the creel, the peg support 30 rises from the lower end.
The bobbin peg 31 of the peg support 30 mounts the lower collar portion 42 of the full bobbin F suspended from the bobbin hanger 10 of the spare rail 3 and further rises. Then, the top portion of the full bobbin B engages with the heavy body 11 of the bobbin hanger 10 shown in FIG. 5 to push up the actuator 12 against the downward biasing force (dotted line in FIG. 5), and the claw piece 14
Is stored in the cylinder shaft 13, and the full bobbin F is removed from the bobbin hanger 10. When the peg support 30 further rises and the heavy horn 11 abuts the bobbin hanger body 10a and the additional load is applied, the bobbin peg 31 is lowered by a predetermined amount L against the force of the spring 37, and the bobbin peg 31 is fully loaded. The reflector 43 of the bobbin F is out of the detection range of the photoelectric switch 41 and outputs an OFF signal. When the OFF signals are output from all photoelectric switches 41 of the peg support 30, a reverse rotation command is output to the lifting motor 27, and the peg support
As for 30, the ascending / descending direction is switched to descending while the full bobbin F is placed. In this way, switching the up and down can be done by using the tab of the bobbin hanger 10.
Since the state change of 14 is detected and performed, the bobbin can be surely attached to and detached from the bobbin hanger 10 even if the height of the bobbin hanger 10 from the floor surface varies. Subsequently, Shinotsugi is carried out, and thereafter, the Shinobatsu full bobbin F and the small bobbin S are exchanged. It should be noted that the photoelectric switches 41 of the peg support 30 do not all output the OFF signal at the same time, and may be delayed. At that time, since the reverse rotation command is not output to the lifting motor 27, the peg support 30 continues to rise,
The bobbin peg 31 already outputting the OFF signal only causes the spring 37 to bend further downward.

Next, another example of the bobbin peg 31 is shown in FIG. In FIG. 4, a limit switch 45 as a detector is arranged in the peg support 30. A peg shaft 32 integral with the bobbin peg 31 is vertically slidably inserted in a hollow shaft 46 rotatably supported by the peg support body 30, and a spring 37 is interposed between the hollow shaft 46 and the bobbin peg 31. A limit dog 47 is integrally fixed to the lower end of the peg shaft 32.

In the above embodiment, the removal from the bobbin hanger with a full bobbin has been described, but the same applies when the bobbin hanger is mounted and when the empty bobbin is mounted on and removed from the bobbin hanger.

As described above, according to the device of the present invention, the detector for detecting that the bobbin peg is lowered by the predetermined axial force applied to the bobbin peg when the claw piece of the bobbin hanger is projected from the cylinder shaft or stored. Since it is provided on the peg support, by switching the ascending / descending direction of the peg support to descending by this detection signal, the height position where the signal from the detector is output, that is, the distance between the bobbin hanger and the peg support is always constant. The peg support can be raised to the height position, and therefore, even if the height position of the bobbin hanger from the floor surface varies, the bobbin can be reliably attached to and detached from the bobbin hanger.
