Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention relates to a bobbin conveying device in a spinning machine, and more specifically to a spinning machine such as a ring spinning machine, a ring twisting machine, etc. that is connected to a winder step. This invention relates to a bobbin conveying device that supplies empty bobbins to the front surface in accordance with the spindle pitch prior to doffing work by an automatic doffing device.

(Prior Art) Conventionally, a full bobbin after spinning is stored in a -H magazine box, and then the required number of bobbins are taken out from the magazine box and transported to a winder. Therefore, a magazine box is required to temporarily store full bobbins, and
During storage and transfer, the surface of the full bobbin may become fluffy.
The disadvantage is that the yarn layer collapses or the ends of the yarn become tangled, making it difficult to pull out the yarn. In order to solve this problem, a spinning machine has been proposed and implemented in which a spinning machine and a wine goo are connected, and the doffed full bobbin is sent directly to the wine goo for rewinding.

Unexamined Japanese Patent Publication No. 50-13644 released on October 29, 1975
Publication No. 0 states that this type of spinning wine goo is equipped with a bobbin conveyor on the spinning machine side that is equipped with a large number of pegs corresponding to the spindles in order to convey full bobbins, and on the wine goo side, a bobbin transport conveyor is installed to transport full bobbins. A conveying means is provided for conveying the full bobbins doffed by the spinning machine and the empty bobbins after winding. Disclosed is a device that moves a bobbin conveyor one pitch at a time, sequentially extracts full bobbins on the conveyor, and supplies them to the wine goo via a yarn replenishing device disposed between the bobbin conveyor and the conveying means. has been done. However,
In this spinning wine goo, when transporting full bobbins from the spinning process to the wine first process, the full bobbins doffed onto the pegs of the bobbin transport conveyor are handled and delivered to the transport means in the wine first process, so the equipment is complicated. There is a problem with becoming.

In order to solve this problem, for example, in Japanese Utility Model Application Publication No. 60-50665 published on April 9, 1985, a peg protruding on the top surface was introduced to transport full bobbins and empty bobbins in the spinning process and the winemaking process. A device has been proposed in which the material is conveyed via a sliding body that is installed and slidably supported on a guide rail and conveyed by a belt conveyor, cylinder, or the like. In this device, the full bobbin doffed by the spinning machine is inserted into the peg of the moving body and transferred to the first winding process, and the empty bobbin after the yarn is wound in the winding unit is placed on the peg of the sliding body. It is then inserted into the spinning process and returned to the spinning process.

(Problems to be Solved by the Invention) In the apparatus for transporting bobbins using the sliding body, the sliding body into which the empty bobbins to be returned from the first winding process to the spinning process is inserted is placed on the belt conveyor. Since the sliding bodies are placed randomly on the spinning machine, it is necessary to transport the sliding bodies returned from the wind ticking stage to the front of the spinning machine with the peg interval corresponding to the spindle pitch of the spinning machine. Conventionally, as a method of arranging the peg spacing of the active body in a state corresponding to the spindle pitch of the spinning machine, the diameter of the sliding body is formed to be the same as that of the sliding body, and each active body is placed in contact with each other along the spindle row. The device was then transported to a predetermined position. However, the pitch of the spindle is not constant in all spinning machines, and at present, spindles with different gauge widths are generally used in the range of 63 to 80 mm. In many cases, the same factory is equipped with a plurality of machines with different spindle pitches, and in this case, it is necessary to prepare a large number of active bodies with different diameters, resulting in an increase in manufacturing costs. Also, currently spinning 8! + The number of spindles is generally around 200 spindles on each side, but there is also a trend toward multiple spindles. Even in the case of 200 spindles on one side, for example, if the manufacturing error of the active body is 0.1111111, the cumulative error will cause as much as 20ml1 of misalignment between the peg and spindle on the sliding body, which will interfere with doffing work using the doffing machine. will come.

As a means to eliminate the inconvenience caused by the accumulation of manufacturing errors, we developed the Japanese Patent Application Laid-open No. 57-16113 published on October 4, 1981.
As shown in FIG. 8, Publication No. 3 discloses that an engagement recess 31a formed on the lower surface of the slider 31 on the guide rail 32 is provided below the guide rail 32 that supports and guides the slider 31. A rod 34 equipped with a plurality of members 33 at predetermined intervals
A feeding device has been proposed that reciprocates with an air cylinder 35 and presses and moves a large number of sliding bodies placed on a guide rail 32 so as to be in contact with each other. When using this device, even if there is a manufacturing error in the diameter of the sliding body 31, since the sliding bodies 31 are compressed and moved in groups by each engaging member 33, the manufacturing error will be reduced by the number of sliding bodies 31 in each group. By staying within the corresponding cumulative error and adjusting the number of sliding bodies 31 in each group, that is, the number of engaging members 33, it is possible to arrange the doffing in a state that does not interfere with doffing. However, this device has a problem in that it has a complicated structure and is expensive. Furthermore, since the sliding body 31 is transferred intermittently by this device, there is also the problem that it takes a long time to complete the supply of empty bobbins to the front of the spinning frame frame.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a guide rail having a peg protruding from its upper surface and guiding a sliding body having a length shorter than the spindle pitch; A conveyor device consisting of an endless belt conveyor for conveying the sliding body was installed along the spindle row of the spinning machine stand. Further, a regulating member that is driven in synchronization with the belt conveyor so as to engage with the sliding body that is continuously supplied onto the continuously driven belt conveyor for a predetermined time is installed at the sliding body entry side end of the conveyor device. It was placed in the department.

(Function) In this invention, a sliding body having a length shorter than the spindle pitch is continuously supplied onto an endless belt conveyor while being supported by a guide rail, and the sliding body is placed on the belt conveyor and placed on a spinning machine. It is transported to the front of the table. and,
When placed on the belt conveyor, the pegs of each sliding body are engaged with a regulating member disposed at the end of the sliding body entry side of the conveyor device for a predetermined period of time, and the movement of the pegs is restricted, thereby maintaining a predetermined interval between the pegs of each sliding body. It is transported sequentially under the condition that the value is regulated. By adjusting the engagement time between the regulating member and the sliding body, the iil! The interval between the first and second bodies is regulated to a predetermined value corresponding to the spindle pitch.

(Example 1) An example embodying the present invention will be described below with reference to FIGS. 1 to 6. As shown in Fig. 2, a plurality of spinning machines 1 and wine goos 2, each of which is installed in parallel, are connected by a conveyance path 3, and full bobbins doffed by the spinning machine 1 are conveyed to the wine goos 2 through the conveyance path 3. Furthermore, the empty bobbin after the thread has been wound by the wine goo 2 is returned to the spinning frame 1 via a conveyance path 3.

On both left and right sides of the frame of the spinning machine 1, a conveyor device 5 is extended in four rows of spindles. The conveyor device 5 is composed of an idle rail 7 having an opening in cross section that guides a sliding body 6 having a peg 6a projecting from its upper surface, and an endless belt conveyor 8 that conveys the sliding body 6. As shown in FIG. 1, the belt 9 of the belt conveyor 8 has a large number of sliding bodies 6.
The guide rail 7 is arranged to be driven on the guide rail 7 in order to prevent the guide rail 7 from being bent when placed on the upper surface thereof.

A rotating shaft 10 is vertically supported near the end of the conveyor device 5 on the sliding body 6 entrance side. A guide rail 7 is placed on the belt conveyor 8 at the upper end of the rotating shaft 10.
A regulating member 11 is fitted so as to be integrally rotatable, and engages with the sliding body 6 that is transported along the driving body and regulates the pitch between the pegs on each driving body to a value equal to the spindle pitch. The regulating member 11 is formed into a disk shape, and has a plurality of (4 circumferences in this embodiment) engagement members on its outer circumference that can engage with the base portion 6b that supports the lower end of the bobbin 12 fitted into the peg 6a. Grooves 13 are formed at equal intervals with the same pitch as the spindle pitch and at positions where they can be engaged with two sliding bodies at the same time. At the lower end of the rotating shaft 10 is a drive shaft 16 of a drive pulley 15 which is rotationally driven by a motor 14 in order to drive the regulating member 11 in synchronization with the belt conveyor 8.
A driven tooth width 18 that meshes with the driving gear 17 that is fitted and fixed to the
is fitted and fixed. The tooth ratio between the driving gear 17 and the driven gear 18 is set to a value such that the moving speed of the belt 9 and the circumferential speed of the engagement groove 13 of the regulating member 11 are the same speed.

Further, a regulating member 11 is provided at the sliding body entry end of the conveyor device 5.
A detection switch P detects the presence or absence of the sliding body 6 to be engaged with the
H1R, Pl-111 are installed, PHIR, PH11
When is in the OFF state, the motor 14 is driven only when there is a signal for reverse rotation (to carry out the yarn from the spinning machine).
In the state where PH1R, PHI Lh<ON, when a signal for normal rotation (supplying empty bobbins to the spinning machine) is input, the motor 14 is rotated in the normal direction, and the leading sliding body 6 is activated by the detection switch PH2R, which is placed at the end of the conveyor device 5. When detected by the PH 21, the motor 14 stops. Note that, as shown in FIG. 5, the conveyance path 3 has an oblique connection portion with the guide rail 7, so that the sliding body 6 slides down onto the belt 9 under its own weight.

Further, when the conveyance path 3 is made horizontal, it is also possible to move the first moving object 6 to the conveyor device 5 by driving the conveyor belt.

Next, the operation of the apparatus configured as described above will be explained. The sliding body 6 with the empty bobbin 12 of the bond wound by the winder 2 fitted into the peg 6a passes through the conveyance path 3 to the end on the entrance side of the conveyor device 5 of the spinning frame frame 1. When the motor 14 is driven while being supplied sequentially, the drive pulley 15
is driven, and the regulating member 11 is rotated clockwise in FIG. 1 together with the rotating shaft 10 via the driving gear 17 and the driven gear 18. When the pedestal portion 6b engages with the outer circumferential portion of the regulating member 11, the movement of the sliding body 6 held on the belt 9 is regulated at the position shown by the chain line in FIG. 6(a). After the pedestal part 6b engages with the engagement groove 13 as shown by the solid line in FIG. from the point where the straight line connecting the engagement groove 13 engaged with the pedestal portion 6b and the center of rotation of the regulating member 11 crosses the guide rail 7 perpendicularly, the pedestal moves in the direction indicated by the arrow. The portion 6b moves in the direction of the arrow along the guide rail 7 while moving toward the outside of the engagement groove 13, so that the straight line connecting the engagement groove 13 and the rotating shaft 10 makes an angle of 45° with the guide rail 7. After moving to this position, the engagement groove 13
It is disengaged and moves in the direction of the arrow. In this state, the pedestal portion 6b of the next sliding body 6 is engaged with the next engagement groove 13. Since the regulating member 11 is rotationally driven at the circumferential speed of its outer peripheral portion at the same speed as the belt moving speed of the belt conveyor 8, the sliding body 6 receives a pressing force when the engagement with the engagement groove 13 is released. It moves at the same speed as the moving speed of the belt 9.

Thereafter, in the same manner, the pedestals 6b of the sliding bodies 6 are sequentially engaged with the engagement groove 13 of the regulating member 11 and sent out one by one. In the case of this device, the spacing between the pegs 6a of each sliding body 6 sent out through the regulating member 11 is the same again as the regulating member 11 rotates 90' from the state shown in FIG. 6(b). This is the distance that the belt 9 of the belt conveyor 8 moves in between. In this embodiment, the moving speed of the belt 9 and the regulating member 11 are
Since the circumferential speeds of the outer peripheries are set to be the same, the distance is 1/4 of the outer periphery of the regulating member 11.

Therefore, by making the length of 1/4 of the outer circumference of the regulating member 11 the same as the spindle pitch, the sliding body 6 is placed on the belt 9 with the distance between the pegs 6a corresponding to the spindle pitch. It is supplied to the front of the spinning frame 1.

(Embodiment 2) Next, a second embodiment of the present invention will be described with reference to FIG. In the embodiment described above, a plurality of engagement grooves 1 are used as regulating members that engage with the sliding body for a predetermined period of time to restrict the movement of the sliding body.
3 and which continuously rotates in synchronization with the belt conveyor 8. In this embodiment, the regulating member 11 has an operating position that prevents the movement of the sliding body 6 on the belt conveyor 8;
This embodiment differs greatly from the previous embodiment in that a rotary lever 19, which is intermittently moved to and from a retracted position that limits the movement of the sliding body 6 by h'F, is provided as a regulating member. The rotating lever 19 is the support shaft 2
0, and is equipped with a cam follower 21 at its base end. cam follower 21
meshes with a drive gear (not shown) fitted to the drive shaft 16 of the drive pulley 15, as in the previous embodiment. l! ! The direction in which the cam 23 comes into contact (
(counterclockwise in FIG. 7) via a spring 24, and is placed in an operating position perpendicular to the guide rail 7 while in contact with the small diameter portion of the cam 23, and when in contact with the large diameter portion of the cam 23. From this state, it is rotated clockwise and placed in a retracted position that allows the sliding body 6 to move. Therefore,
In this device as well, after the engagement between the rotary lever 19 and the sliding body 6 is released, the belt 9 of the belt conveyor 8
By setting the moving distance to be the same as the spindle pitch, it becomes possible to sequentially feed the sliding bodies 6 onto the belt 9 of the belt conveyor 8 in a state corresponding to the spindle pitch.

Note that the present invention is not limited to the above-mentioned embodiments. For example, the belt conveyor 8 and the regulating member 11 disposed on both the left and right sides of the spinning machine 1 may be configured to be driven by one motor. , the size of the regulating member 11 and the engagement groove 13
The number of rotating levers 1 in the second embodiment can be changed.
It is also possible to arbitrarily change the shape, structure, etc. of each part of the sheath without departing from the spirit of the present invention, such as by providing a regulating member driven by a solenoid in place of 9.

Effects of the Invention As detailed above, according to the present invention, there is no need to prepare various sizes of sliding bodies having pegs into which the bobbin is inserted in accordance with the spindle pitch, and it is possible to use sliding bodies of the same size. The sliding body can be conveyed to the front of the spinning machine table in accordance with the spindle pitch, and the structure of the device is simple, reducing costs, and the pegs can be conveyed continuously instead of intermittently. This has the excellent effect of shortening the feeding time to the front of the spinning machine stand.
