[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for attaching and detaching a roving bobbin placed on a bobbin peg to a bobbin hanger at an upper position.

[0002]

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) and a spinning machine for spinning creels (Japanese Patent Laid-Open Nos. 62-53425 and 64). −
No. 20335), 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 while the bobbin B is 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. Thereafter, the peg support 30 is lowered by a signal generated by the engagement of the rising end limit switch LS fixed to the frame 18 and the dog 51 of the peg support 30. Since the actuator 12 is urged downward, an axial force that opposes the urging force is generated downward when the claw piece 14 is projected and stored, and this force causes the bobbin peg 31 to urge the spring 37 upward. It is designed to be lowered by a predetermined amount with respect to the bobbin support 30 against the spring force of.

[0003]

According to the above, since the rising end limit switch LS is fixed to the frame 18, the up / down switching position of the peg support 30 is constantly constant from the floor surface. If the height positions of the bobbins are not the same from the floor surface, the bobbin cannot be smoothly attached to and detached from the bobbin hanger 10. However, a large number of bobbin hangers 10 are suspended in the longitudinal direction, for example, for one roving machine or one spinning creel, for example, on the carriage bar 5. Therefore, all these bobbin hangers 1
It is quite troublesome to make the height of 0 the same from the floor, and the carriage bar 5
The height of the guide rail 6 may change. Therefore, the height of the bobbin hanger 10 is likely to vary,
For example, when it is too high, there is a problem that a mistake in attachment and detachment occurs.

[0004]

In order to solve the above-mentioned problems, a roving bobbin attaching / detaching device of the present invention moves a peg support having a bobbin peg up and down by forward and reverse rotations of a lifting motor.
A roving bobbin attaching / detaching device configured to attach / detach a roving bobbin placed on a bobbin peg to / from a bobbin hanger in an upper position by a pushing force of a peg support, and in the lifting motor, when the peg support is raised. Control to connect a load detection device that detects the lifting motor load, and based on the load signal from this load detection device, rotate the lifting motor in the reverse direction when the lifting motor load reaches the specified load for attaching and detaching the roving bobbin to the bobbin hanger. It is characterized by having a device.

[0005]

Operation: The peg support having the bobbin peg is moved up and down by forward and backward rotation motors, and the roving bobbin on the bobbin peg is attached to and removed from the bobbin hanger by the pushing force of the peg support.
At this time, the load detecting device detects the lifting motor load when the peg support is raised, and when the lifting motor load reaches a predetermined load when the bobbin hanger is attached to or detached from the roving bobbin, the controller reverses the lifting motor. Rotate. Thus, the predetermined load of the lifting motor when the roving bobbin is attached to or detached from the bobbin hanger is detected, so that the bobbin attachment / detachment operation is reliably performed even if the height position of the bobbin hanger varies.

[0006]

[Embodiment] This invention is applied to a spinning machine 1 in a spinning creel.
The description will be given by applying it to No. 5. In FIG. 3, 1 is a front row of the creel, 2 is a rear row of the creel, 3 is a spare rail (similar to the guide rail 6), 4 is a bobbin carriage guided by the spare rail 3, and the carriage bar 5 has the above-mentioned publicly known wire. The bobbin hangers 10 are mounted at the bobbin pitch in the longitudinal direction of the spinning creels. The converting machine 15 is disclosed in Japanese Unexamined Patent Publication No. 62-53425, and has a plurality of bobbin pegs 31 in the longitudinal direction at the bobbin pitch of the spinning creels.
Up and down of a pair of peg support pairs 29, 30 each having
Back and forth movement, Shino end exit nozzle 16 and Shino joint head 17
The small bobbin S located in the front row 1 of the creel is replaced with the full bobbin F, then the small bobbin S is taken out, and the full bobbin F of the spare rail 3 is taken out from the small bobbin S. The bobbin hanger 10 is suspended.

FIG. 1 shows an elevating / retracting device for a peg support 30 for a full bobbin. A lower part 20a of the lifting body is guided up and down by a guide rod 19 standing upright 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 the rocking motor 24 by a gear train 22 and a rocking lever 23 in the lift 20. By these operations, the bobbin peg 31 of the peg support 30 moves to a position directly below the spare rail 3 and the creel. It is arranged so as to move between positions immediately below the front row 1. Sprockets 25 above and below the frame 18
The chain 26 wound between them is connected to the lower portion 20a of the lifting body 20, and the lifting motor 27 moves the peg support 30 into the lower portion of FIG.
Remove the bobbin B from the lower end shown in Fig.
Further, it is designed so that it can be raised and lowered with respect to a rising position for hanging (it 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. 2, the 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. Flange member 36 sandwiched between peg shaft 32 and bearing 35
A spring 37 is interposed between the bobbin peg 31 and the bobbin peg 31 to urge the bobbin peg 31 upward, and a cap-shaped head portion 32 a of the peg shaft 32 prevents the bobbin peg 31 from coming off. A belt pulley 38 is key-connected to the lower end of the peg shaft 32. The belt pulley 38 is rotated via a belt 39 by a rotation motor (not shown), and after the lead-out nozzle 16 and the connecting head 17 connect the small bobbin S with the full bobbin F on the bobbin peg 31. The bobbin F is sent out and rewound, but this peg rotation structure is not an essential requirement of this invention.

Next, the control of the lifting motor 27 will be described. In FIG. 4, the lifting motor 27 has a three-phase power supply line RST.
The phases are connected via the contacts of the forward rotation and reverse rotation relays MSF and MSR, and the load detection device 60 is attached to the power supply lines R phase and T phase. The load detection device 60 is a well-known current converter, and the built-in Hall elements CTR and CTT detect the load current of the lifting motor 27 flowing in the power supply lines R phase and T phase, and have a built-in voltage proportional to the detected current. It is amplified by a amplifier and output. An A / D converter 61 that converts an output voltage (load signal) from the load detection device 60 into a digital signal is connected to the load detection device 60, and the converter 61 is further connected to a control device 62 so that a digitized load is generated. It is designed to transmit signals.

The control device 62 is, for example, a sequencer, and the load of the lifting motor 27 when the full bobbin F on the peg support 30 is attached to and detached from the bobbin hanger 10 is set and stored as a predetermined load. When the digital signal corresponding to the motor load that is input when the peg support 30 is raised reaches this predetermined load, the forward rotation relay MSF connected to the output side is demagnetized, and the reverse rotation relay MSR is excited to lift and lower the motor 27. Is programmed to reverse and rotate the peg support 30 down.

When the small bobbin S of the fine spinning creel is positioned in the front row 1 of the creel, the elevating motor 27 is driven to rotate and the peg support 30 is raised from the lower end. The bobbin peg 31 of the peg support 30 mounts the full bobbin F hung on the bobbin hanger 10 of the spare rail 3 and further rises. Then, the top portion of the full bobbin F engages with the heavy bobbin 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. 52), and the claw piece 14 to the cylinder shaft 13.
Then, the full bobbin F is removed from the bobbin hanger 10. Further, the peg support 30 rises, the heavy sledge 11 contacts the bobbin hanger body 10a and tries to push it up, and the load of the lifting motor 27 increases. The load increase of the lifting motor 27 is detected by the load detection device 60, and this load is detected by the A / D converter 6
It is digitized by 1, and the control device 62 is input.

In the controller 62, when the load of the lifting motor 27 reaches the predetermined load, the forward / reverse relay MSF,
The MSR is switched to rotate the elevating motor 27 in the reverse direction, and the elevating direction is switched to the descending direction with the full bobbin F mounted on the peg support 30. In this way, the lifting / lowering switching is performed when the load of the lifting motor 27 reaches a predetermined load for loading / unloading the full bobbin F when the bobbin is attached / detached. The bobbin can be attached to and detached from the bobbin. Subsequently, Shinotsugi is carried out, and then the Shinobetsu full bobbin F and the small bobbin S are exchanged.

In the above embodiment, the removal of the full bobbin from the bobbin hanger has been described, but the same applies when the bobbin hanger is attached to and detached from the bobbin hanger. Further, the present invention is not limited to the above-described embodiment. For example, instead of the current converter that detects the load current of the lifting motor, a rotation detector is provided on the motor shaft or a rotating object that is interlocked with this, and the roving bobbin is provided. When a detected rotation speed (load signal) reaches the predetermined rotation speed by storing in the control device a predetermined rotation speed corresponding to a predetermined load when the bobbin hanger is attached or detached, the lifting motor is driven by the output signal of the control device. May be reversed.

[0014]

As described above, according to the device of the present invention, when the bobbin is attached / detached, the load detection device detects that the load of the lifting motor has reached a predetermined load for attaching / detaching the roving bobbin. By switching the raising / lowering direction of the body to the lowering direction, the peg support can be raised to a position where the bobbin hanger and the roving bobbin can be reliably attached / detached, and therefore the height position from the floor surface to the bobbin hanger varies. The bobbin can be securely attached to and detached from the bobbin hanger.
