Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a full bobbin delivery device for a spinning machine.

Conventional technology Recently, as part of rationalization of Rovering machines,
In order to improve operating efficiency, there is a remarkable trend toward higher speeds and larger packages, and with this, streamlining the work of replacing tubes after full tubes and discharging full bobbins has become an urgent issue. In other words, manually handling full bobbins in large packages is not only extremely labor-intensive for workers, but also significantly increases the time required for the work, reducing the operating efficiency of the roving frame. . For this reason, automation of these operations has been desired, and various devices have been devised to achieve automatic discharge of full bobbins and automatic supply of empty bobbins.

However, in the conventional full bobbin discharge device,
The full bobbins discharged from the conveyor means are stored in a transport vehicle in a horizontally stacked state and transported to the next process, which has the disadvantage that the rovings are easily damaged. The work of removing the products from the transport vehicle had to be done manually, which was a factor that hindered the automation of the next process.

In addition, in order to eliminate the above-mentioned drawbacks, a conveyor rail is arranged under the ceiling beam of the factory, and full bobbins discharged from the conveyor means by a full bobbin automatic discharge device are suspended on a conveyance magazine suspended on the conveyor rail. A method has also been proposed in which the material is transported to the next spinning step. However, in spinning factories, the efficient operation of spinning machines plays a large role in improving productivity, so spinning machines are operated 24 hours a day or close to that. Therefore, it is necessary to always keep a stock of full bobbins unloaded from the roving frame, and in addition to the transport route from the conveyor means to the spinning machine, a large number of conveyor rails must be installed to store the full bobbins, which increases equipment costs. It has the disadvantage of being bulky.

Purpose This invention was made to eliminate the above-mentioned conventional defects, and its purpose is to transfer the full bobbin unloaded from the roving frame onto a trolley for transporting the roving to the next process without damaging the roving. It is an object of the present invention to provide a full bobbin unloading device for a spinning machine that can be replaced and easily automated in the next process.

It is placed on the bobbin holder 17 in this state.

After all the full bobbins 40 are placed on the bobbin holder 17 as described above, the cart 37 with empty bobbins 54 inserted into all the pegs 43 is carried into one end of the machine base. The truck 37 moves along the rail 38, and as shown in FIG. The bobbin 54 stops at a position corresponding to the empty bobbin transfer device 58. When the empty bobbin 54 is placed in a position corresponding to the empty bobbin transfer device 58, the phototube PH3 (shown in FIG. 11) detects the empty bobbin 54 and drives the drive gear 27 based on the detection signal. The motor (not shown) is started, and the driving gear 27 is driven so that its rotation is caused by the rotation of the slide key 2.
6, the power is transmitted to the drive sprocket 14 via the clutch body 25, clutch disc 21 and driven shaft 20, and the chain conveyor 16 is driven.
The bobbin holder 17 attached to the chain conveyor 16 moves in the direction of the arrow in FIG. 10 with the full bobbin 40 placed thereon. The motor continues to drive until the pipe replacement of all the spindles is completed unless an abnormal situation occurs.

On the other hand, the empty bobbin transfer device 58 is activated based on the detection signal from the phototube PH3, and the four empty bobbins 54 loaded in the first row of the truck 37 are taken out from the truck 37 and placed in the empty bobbin supply box 55. be transferred to. When the completion of transfer of the empty bobbin 54 to the empty bobbin supply box 55 is confirmed by a phototube (not shown) installed at a predetermined position, the intermittent feeding device 45 is activated in response to the signal. first,
As shown in FIG.
The cylinder 5 is engaged with the cylindrical body 42 of the cylinder 5 and the carriage fixing lever 48 is held in the non-engaging position.
0 is activated, and the truck 37 is moved forward (to the left in FIG. 11) by the interval between the pegs 43 together with the movable body 51. As shown in FIG. 20, the empty bobbins 54 in the second row correspond to the empty bobbin transfer device 58, and the cylindrical body 42 on which the empty bobbins 54 in the first row were placed corresponds to the full bobbin insertion device. The state corresponds to 61. Next, lever 4 for fixing the trolley
The solenoid 47 that was holding 8 in the disengaged position
In the OFF state, the trolley fixing lever 48 rotates to the engagement position with the cylinder 42, and the cylinder 52 for operating the rotation lever 53 operates to move the rotation lever 53 to the non-engagement position. Rotate until. In this state, the cylinder 50 operates again, and the moving body 5
1 only moves to the right in FIG. 20 and returns to the original position shown in FIG. and rotation lever 53
is rotated to the engagement position with the cylindrical body 42 by the operation of the cylinder 52, and the solenoid 47 is turned on, so that the trolley fixing lever 48 is rotated to the non-engagement position and is held at the same position. .

On the other hand, as the cart 37 moves, the empty bobbin 54 in the second row is detected by the empty bobbin detection phototube PH3, and the empty bobbin transfer device 58 is activated based on the detection signal. and empty bobbin transfer device 58
The second row of empty bobbins 54 are extracted from the pegs 43 and held in a suspended state without being transferred to the empty bobbin supply box 55.

Now, as the chain conveyor 16 moves due to the rotation of the drive sprocket 14, the bobbin holder 17 on which the full bobbin 40 is placed moves in the direction of the arrow in FIG. When the bobbin holder 17 moves to the circumferential portion, the axial center of the bobbin support cylinder 17a coincides with the axial center of one of the four mounting holes 28 provided on the drive sprocket 14. When the drive sprocket 14 rotates from this state, the push-up member 30 fitted into the mounting hole 28 starts to protrude from the mounting hole 28 against the elasticity of the coil spring 32 due to the action of the cam surface 35. When the bobbin holder 17 moves to around 10 degrees in FIG. As a result, the flange portion 40 is tilted toward the center of rotation of the drive sprocket 14, as shown in FIGS. 21 to 23.
The external use of b is the vertical part 76 of the guide bars 76, 77.
It is supported in contact with a and 77a at two points.

When the bobbin holder 17 continues to move in the circumferential portion from this state, the flange portion 40b rises along the vertical portions 76a, 77a of the guide bars 76, 77, and then the inclined portion 76 of one of the guide bars 76
b and moves toward the center of both support members 70 and 71 with its upper part engaged with the inclined part 77b of the other guide bar 77,
The inclination of the full bobbin 40 gradually decreases. Flange portion 40b guided between both supporting members 70 and 71
As shown in FIGS. 24 and 25, the first support member 70 is engaged with the cam surface 70c of one of the support members 70
is rotated upward against the spring force of the torsion spring 74, and then engaged with the lower surface of the support portion 71a of the other support member 71 to rotate the support member 71 upward. Then, as the full bobbin 40 further rises, both the support members 70 and 71 are disengaged from the flange portion 40b and returned to their original states by the spring force of the torsion springs 74 and 75. And approximately in Figure 7
At around 45 degrees, the upward movement of the push-up member 30 reaches its maximum point, and the full bobbin 40 becomes almost vertical. When the drive sprocket 14 is further rotated and the push-up member 30 begins to descend, the flange portion 40b moves toward both support members 70. , 71, and the flange portion 4 is supported by the phototube PH1.
0b is detected. At this time, the full bobbin 40 is
As shown by the solid line in Figures 1 and 22, the large diameter portion 40
a is completely removed from the bobbin support cylinder 17a and suspended.

That is, as the bobbin holder 17 moves around the circumferential portion along the arrow in FIG.
The flange portions 40b are A, B,
The flange portion 40b moves in the order of C, D, and E, and the flange portion 40b moves to C.
The full bobbin 40 is most inclined when it is in the E position, and becomes almost vertical at the E position.

When the bobbin holder 17 moves from this state to a position where the push-up member 30 protruding into the large diameter section 40a of the full bobbin 40 descends to the outside of the large diameter section 40a, the outer peripheral surface of the bobbin support cylinder 17a engages with the limit switch LS. . Then, due to the detection signal from the phototube PH1 and the ON signal from the limit switch LS, the clutch of the drive shaft 109a is switched to the motor 10.
Connected to the output shaft of 9. The motor 109 is driven at the same time as the chain conveyor 16, and continues to be driven until all spindles have been replaced unless an abnormal situation occurs. Therefore,
The drive shaft 109a is connected to the motor 10 by the clutch.
9, the drive of the output shaft of the motor 109 is transmitted to the rotation shaft 101 via the drive shaft 109a, pulley 110, belt 111, and pulley 108, and the drive pulley 102 rotates counterclockwise in FIG. The toothed belt 107 moves in the direction of the arrow in the figure. As a result, both the supporting members 7
The full bobbin 40, which had been suspended above 0,71, has its flange portion 40b located between the engaging pieces 112a and 112b, and is pushed by the engaging piece 112a and transferred onto the rail 67 of the full bobbin holding device 60. Ru. When the toothed belt 107 moves by the distance between the engagement pieces 112a, that is, the interval within the column of the cart loading section, the tip of the engagement piece 112a is moved by a phototube (not shown) disposed at a predetermined position. The detection signal releases the connection between the clutch of the drive shaft 109a and the output shaft of the motor 109, and the brake is activated to stop the rotation of the drive shaft 109a and the toothed belt 107 as well. In this way, the full bobbin holding device can receive full bobbins while changing the interval within the row of the bogie loading section. The full bobbin 40 is suspended and supported at the center of the rail 67 of the full bobbin holding device 60, as shown by the solid line in FIG.

Thereafter, the full bobbin 40 placed on the bobbin holder 17 in the same manner as above is suspended above the supporting members 70, 71 by the action of the full bobbin discharge mechanism and the guide bars 76, 77, and the phototube PH1 and Each time the limit switch LS is turned on, the toothed belt 107 is transferred by a predetermined amount and the bobbin 4 is filled.
0 are sequentially transferred onto the rail 94 at the full bobbin insertion position 61. When four full bobbins 40 are suspended on the rail 94 as shown by chain lines in FIG. 26, the phototube PH2 detects the rightmost full bobbin 40, and the cylinder 81 is actuated by the detection signal. .

The piston rod 83 is moved by the operation of the cylinder 81.
is projected downward, and the full bobbin insertion device 61 begins to descend. The full bobbin insertion device 61 descends and the full bobbin 4 is suspended between the support portions 94a of the rail 94.
When the peg 43 of the truck 37 in the large diameter portion 40a of the rail 94 is inserted, the cam 97 protruding from the inner surface of the rail 94 starts to come into contact with the cam roller 100. As a result, both rails 94 are rotated outward against the spring force of the tension spring 96, as shown by chain lines in FIG.
The engagement between the rail 94 and the support portion 94a is released. As shown in FIG.
placed vertically on 2. Next, when it is confirmed by a limit switch (not shown) that the piston rod 83 has protruded to a predetermined position, the piston rod 8
3 is drawn into the cylinder 81, and the full bobbin insertion device 61 rises to its original position. When the engagement between the cam 97 and the cam roller 100 is released due to the rise of the full bobbin insertion device 61, both rails 94
is rotated to its original position by a tension spring 96.

When the return of the piston rod 83 to the predetermined position is confirmed by a limit switch (not shown), the open/close feed device 45 is activated, and the cart 37 is moved in the same manner as described above, and the empty bobbin 54 in the third row is transferred. It comes to a position corresponding to device 58. Then, when the phototube PH3 detects the empty bobbin 54, the empty bobbin transfer device 58 is activated in the same manner as described above, and the empty bobbin 54 in the third row is extracted from the peg 43 and suspended from the empty bobbin transfer device 58. maintained in the state. Note that, before the intermittent transfer device 45 is activated, all the empty bobbins 54 in the second row that had been suspended in the empty bobbin transfer device 58 are supplied with empty bobbins based on the detection signal from the phototube PH2. It is transferred to box 55.

Thereafter, the full bobbins 40 placed on the bobbin holder 17 in the same manner as described above are sequentially transferred onto the cart 37, and the bobbin holder 1 from which the full bobbins 40 have been removed is
Empty bobbins 54 are sequentially supplied and placed on the empty bobbin supply box 55. Then, the pipe replacement work is completed while the chain conveyor 16 moves one round.

In order to efficiently perform pipe changing work in a short time, it is necessary to increase the transfer speed of the chain conveyor 16, but if the transfer is always performed at a high speed, the full bobbin insertion device 61 will move up and down. During this time, the full bobbin 40 is removed from the bobbin holder 17, and the hanging onto the supporting members 70, 71 is completed.
Support part 94 of rail 94 of full bobbin insertion device 61
The full bobbin transfer device 62 operates in a state where the heights of the top surface a and the top surface of the rail 67 of the full bobbin holding device 60 do not match, causing trouble in operation. However, in the apparatus of this embodiment, the chain conveyor 16 moves at two speeds, that is, at low speed when the full bobbin insertion device 61 is moving up and down and during the subsequent movement of the trolley 37, and at high speed at other times. , the pipe replacement work can be carried out efficiently and in a short time without the above-mentioned problems.

Note that the present invention is not limited to the above-mentioned embodiment. For example, if the cart 37 is used only for transporting full bobbins 40 and the empty bobbins 54 are supplied onto the bobbin holder 17, a large number of empty bobbins 54 may be stored. This may be carried out using an empty bobbin supply device equipped with a storage section. Further, as shown in FIG. 30, a conveyor 114 is installed along the machine stand separately from the bobbin rail 6 of the spinning machine, and a doffing device 115 takes out the full bobbin 40 from the bobbin rail 6 and transfers it to the conveyor 114. The present invention may also be applied to a type of device that is delivered above. In this case, it can be easily applied to existing spinning machines.

Effects As detailed above, the full bobbins received from the conveyor are suspended and transferred to the upper part of the trolley by adjusting the interval between them to the loading section of the trolley, and the full bobbins are loaded onto the trolley only by the lowering action of the full bobbins. I started to
In addition to this, by moving the cart intermittently,
The full bobbins are arranged independently and in the same state on the cart.

In this way, full bobbins are smoothly transferred from the conveyor to the cart, so that the roving threads of the full bobbins unloaded from the roving frame are not damaged, and moreover, they are supported on the flat loading section. It makes it easier to take out work in the next process, facilitates automation, and works effectively as a stock means.
