Description

[Detailed Description of the Invention] Object of the Invention (Field of Industrial Application) The present invention relates to a positioning device for a conveyor peg in a spinning machine, and more specifically, a device for positioning a conveyor peg in a spinning machine, and more specifically, a device for positioning a conveyor peg in a spinning machine. This relates to a conveyor peg positioning device for a conveyor peg of a conhair device that carries bobbins (shell feeding) using a sliding body with a P/knob protruding from the top surface (prior technology). For such spinning machines, in order to facilitate the automatic pipe change operation by the doffing machine, a conveying device is required to supply empty bobbins to the front of the spinning machine in a state that corresponds to the spindle pitch, and to discharge the doffed full bobbins. Become.

As this conveyance device, a conhair device is used, in which pegs are protruded from an endless conhair belt corresponding to the spindle pinoch. However, the conveyor device has the disadvantage that the conveyor belt elongates due to long-term use, and the elongation increases, causing deviations in the set peg intervals and hindering the automatic tube change operation of the doffing machine. .

In order to solve this problem, in Japanese Patent Application Laid-Open No. 57-161133 published on October 4, 1988, a guide rail 72 is arranged around the spinning frame 71, as shown in Fig. 8-9.
A peg 73a is provided on the upper surface of the guide rail 72, and a locking recess 73b is formed on the lower surface. A feeding device is provided in which a rod 76 is installed so as to be slidable in contact with each other and is equipped with a plurality of engaging members 75 at predetermined intervals below the guide rail 72 and reciprocally operated by a cylinder 77. A conveyor device has been proposed in which the sliding body 73 is sequentially moved along the guide rail 72 by the feeding device.

(Problem to be Solved by the Invention) In the apparatus for transporting bobbins using the sliding bodies, the length and diameter of the sliding bodies are formed to be the same as the spindle pitch, and the sliding bodies are brought into contact with each other. By moving and arranging the pegs along the spindle row in this state, the pitch of the pegs corresponds to the spindle pitch. However,
The spindle pitch is not constant in all spinning machines, and several different gauge widths are currently in use, generally ranging from 63.5 to 8C1+m. In many cases, the same factory is equipped with machines with different spindle pitches, and in that case, it is necessary to prepare a large number of sliding bodies with different diameters, resulting in high manufacturing costs (and
There is a problem that storage and sorting become complicated.

Furthermore, although currently spinning machines generally have about 200 spindles on each side, 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 sliding body is 0°1 fin, the cumulative error will result in an error of 20 degrees in the arrangement of the sliding body peg and spindle, which will interfere with doffing work using a doffing machine. Come. In order to eliminate the inconvenience caused by the accumulation of manufacturing errors, in the conveyor device, a plurality of engaging members that engage with the locking recesses of the sliding body are provided at predetermined intervals, and each engaging member is connected to the sliding body on the guide rail. Since a plurality of spindles are pressed and moved in groups, the structure is complicated and the cost is high, and as the number of spindles increases, the nuclear problem becomes more prominent. In addition, this device also has the problem that all the sliding bodies must be transferred at the same time, resulting in high power consumption.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, in this invention, a sliding body with a peg protruding from its upper surface and a short length equal to the spindle pitch is installed along the spindle rail. A conveyor device that can slide on an extended guide rail was installed on the spinning machine stand. The working machine moving along the conveyor device is driven in synchronization with the movement of the working machine, and is sequentially placed in a predetermined position with the pegs of the sliding bodies arranged in a row on the guide rail in contact with each other. A time-engageable positioning member is provided.

(Function) In this invention, before the work machine is operated, the sliding body in which the empty bobbin is inserted into the peg is placed in a row on the guide rail in a state that they are in contact with each other from a position that approximately corresponds to one end of the spindle row. ) lit person. In this state, the working machine moves at a constant speed along the conveyor device, ie, the spindle rail. As the working machine moves, a positioning member provided on the working machine is driven in synchronization with the movement of the working machine and sequentially engages with the pegs of the sliding body arranged on the guide rail for a predetermined period of time. The positioning member engages with the peg for a predetermined period of time, thereby sliding the sliding body on which the peg protrudes and the sliding body located ahead of the peg in the direction of movement of the working machine by a certain amount;
The sliding body moves while being positioned sequentially from the front side in the direction of movement of the working machine to the position corresponding to the spindle. Although the same number of sliding bodies as the number of spindles are arranged on the guide rail, the number of sliding bodies pushed by the positioning member gradually decreases as the work machine moves.

(Example Work) Hereinafter, an example in which the apparatus of the present invention is installed on a continuous moving type doffing machine as a working machine will be described with reference to FIGS. 1 to 6. As shown in FIG. 1, the doffing machine 1 runs along the spinning frame frame 2 via rails 3 fixed to the spinning frame frame 2 and guide rollers 5.6 that engage with guide rails 4.

A belt conveyor is provided to convey the sliding body.

The guide rail 9 is equipped with disk-shaped sliding bodies 13 having a diameter shorter than the pitch of the spindles 12 of the spindle rail 10 so as to be slidable on the belt 11 in the same number of rows as the spindles 12. A peg 13b having a pedestal part 13a is protruded from the center of the upper surface of the sliding body 13, and the lower end of the bobbin is supported by the pedestal part 13a while the bobbin is fitted onto the peg 13b.

At the upper part of the doffing machine 1, a full bobbin lifting device 15 is provided which functions to pull out the full bobbins 14 one by one from the spindle 12. Below the full bobbin lifting device 15, there is a full bobbin pulling device I5 for inserting the full bobbin 14 pulled out from the spindle 12 into the peg 13b of the sliding body 13 supported on the guide rail 9. A bobbin shooter 17 that guides the bobbin insertion device 16 is provided. A shutter 18 is provided at the lower end of the bobbin shooter 17, and after the full bobbin 14 doffed from the spindle 12 and sent to the bobbin shooter 17 is temporarily held in the bobbin shooter 17, the shutter 18 is opened. It is designed to be fed into a bobbin insertion device 55m16.

In the full bobbin insertion device 16, a support bracket 21 whose upper part is bent into a U-shape is fixed to the tip of a swinging lever 20 whose base end is rotatably supported by a support shaft 19. grip members 23a, 23b via hinges 22a, 22b.

a.

27b is provided. An engagement lever 28 is fitted to the other end of one support shaft 24a so as to be integrally rotatable, and a latch member 29 is fitted to the other end of the other support shaft 24b so as to be integrally rotatable. The gripping member 23b is biased to rotate toward the closed position (clockwise in FIG. 2) by a torsion spring 30 (shown in FIG. 3) interposed between the stop member 29 and the hinge 22b. Above the base end of the swing lever 20, a swing lever 31 formed in a substantially L-shape is rotatably supported by a support shaft 32 at its bent portion. One end of the swinging lever 31 is connected to the swinging lever 20 by a link 33, and a cam is fitted on the other end of the swinging lever 31 so that it can rotate integrally with a rotating shaft 34 that is driven to rotate in synchronization with the screw roller 8. A cam follower 36 is attached which engages 35. The swing lever 31 is always urged to rotate in the direction in which the cam follower 36 comes into contact with the cam 35 by a spring 37.

Furthermore, an engagement pin 38 is fixedly provided below the engagement lever 28.

Next, a positioning device 3 positions the sliding bodies 13 disposed on the guide rail 9 so as to be in contact with each other so that the interval between each peg 13b corresponds to the spindle pitch.
9 will be explained. A support shaft 41 is vertically supported at the tip of a support bracket 40 disposed below the full bobbin insertion device 16 and on the side opposite to the moving direction of the doffing machine 1. An impeller 43 serving as a positioning member is rotatably supported in which four engaging grooves 42 that can be engaged with the base portion 13a of the peg 13b are formed at equal pitches. The impeller 43 has a size such that the circumferential pitch at the center of the engagement groove 42 is the same as the spindle pitch, that is, the diameter of a circle passing through the center of the engagement groove 42 is D=((spindle pitch) )/π (where n is the number of engagement grooves).

Behind the support bracket 40 (on the left in FIG. 2), a driven shaft 44 is supported by a bracket 45 (shown in FIG. 3) in parallel with the rotating shaft 34, and one end of the driven shaft 44 has a A pulley 46 and a bevel gear 47 are fitted to the other end of the pulley 46 so as to be rotatable together. The driven shaft 44 is rotated at half the speed of the rotating shaft 34 via a belt 49 that is wound between the pulley 46 and a pulley 48 fitted on the rotating shaft 34. A rotating shaft 50 is vertically supported by a bracket 51 below the bevel gear 47, and a bevel gear 5 that meshes with the bevel gear 47 is attached to the upper end of the rotating shaft 50.
2, a pulley 53 is fitted to the lower end thereof so as to be rotatable together. A belt 55 is wound between the pulley 53 and a pulley 54 formed integrally with the impeller 43, so that the impeller 43 is driven to rotate in synchronization with the rotating shaft 50. The bevel gear 52 is formed to have twice the number of teeth as the bevel gear 47, so that the rotational speed of the driven shaft 44 is reduced to 1/2 and transmitted to the rotating shaft 50. That is, the impeller 43 rotates 1/4 while the rotating shaft 34 rotates once. Further, the impeller 43 is connected to the engagement 14
The rotational speed on the pitch circle of No. 2 is the same as the moving speed of the doffing machine 1.

Next, the operation of the doffing machine constructed as described above will be explained.

During the spinning operation of the spinning machine, as shown in Figure 4, an empty bobbin (
The slider 13 (not shown) fitted into the peg 13b comes into contact with the spindle 12 on the entry side of the doffing machine 1 (right side in FIG. 4) from a position that almost corresponds to the guide rail 9.
Supply is arranged within. When the spinning machine stops in response to a full tube command, the doffing machine 1, which is carried by a carrier (not shown) to a position corresponding to the full tube stand, starts moving along the rail 3, that is, the guide rail 9. The doffing machine 1 doffs the full bobbin 14 from the spindle 12 using the full bobbin lifting device 15, then pulls out the empty bobbin from above the peg 13b using the empty bobbin lifting device (not shown), and transfers the full bobbin 14 to the spindle. Insert an empty bobbin into 12, and transfer the doffed full bobbin 14 to peg 1, where the empty bobbin is pulled.
3b is inserted by the full bobbin insertion device 16.

When the doffing machine 1 approaches the first spindle 12, the rotating shaft 34 is driven to rotate, and the pulley 48, belt 49,
The impeller 43 is rotationally driven in the clockwise direction in FIG. 3.5 integrally with the IJ 54 via the IJ 46, driven shaft 44, bevel gear 47, 52, rotating shaft 50, pulley 53, and heald 55. The impeller 43 is at position A shown by the chain line in FIG. As the doffing machine 1 moves, the impeller 43 moves in parallel along the guide rail 9 together with its support shaft 41 while rotating clockwise in FIG. 5(a). While moving from position 1 shown as A to position B in FIG. It moves I+ in the direction of movement (to the left in FIG. 5(a)).

In this state, the engagement groove 42 comes into contact with the advancing side peripheral surface of the doffing tal of the pedestal portion 13a of the sliding body 13. The impeller 43 further rotates from this state, that is, the position shown by B in FIGS.
), the spindle 41 of the impeller 43 moves from the position shown at B to the position shown at C in FIG. 5(b). On the other hand, the sliding body 13
In the meantime, the doffing machine 1 moves from the position indicated by b to the position indicated by C.
It is moved 12 times in the direction opposite to the direction of travel. In this state, the impeller 43 has a positional relationship with respect to the next sliding body 13 as shown by the chain line in FIG. 5(a). Furthermore, the impeller 43 is translated and rotated from the position shown by C in FIG. 5(b), whereby the engagement between the engagement groove 42 and the pedestal portion 13a of the sliding body 13 is released. Therefore, the impeller 43 moves from A to C (π
While moving in parallel by a distance of D)/4, the sliding body 13 moves from a to C by a distance of <i+-12). Thereafter, similarly to the above, each time the impeller 43 rotates 1/4 rotation, the sliding body 13 moves <1+-7! z), and the intervals between the pegs 13b are positioned at the same pitch as the spindle pitch.

On the other hand, the full bobbin 14 sent to the bobbin shooter 17 and placed on the shutter 18 is sent out to the full bobbin insertion device 16 by the opening operation of the shutter 18. The full bobbin 14 sent out from the bobbin shooter 17 is gripped by the re-gripping members 23a and 23b waiting at the upper movement position 1. Then, from this state, the cam 35 is rotated, the swing lever 20 is rotated clockwise in FIG. The re-gripping members 23a and 23b are rotated and moved downward together with the support bracket 21 while gripping the fully loaded bobbin 14. During the downward movement when the lower part of the fully loaded bobbin 14 is partially inserted into the peg 13b, the engagement lever 28 is engaged with the engagement pin 38, and the engagement lever 28 is rotated clockwise together with the support shaft 24a.Then, the lever 25a is rotated clockwise together with the support shaft 24a, and the link 2
6, the lever 25b is rotated counterclockwise. As a result, the re-gripping members 23a and 23b are rotated outward to release the gripping state of the fully loaded bin 14, and the fully loaded bin 14 is inserted into the peg 13b as shown in FIG. The full bobbin 14 is inserted into the peg 13b when the impeller 43 is in the position shown by B in FIG. 5(a).

(Embodiment 2) Next, a second embodiment of the present invention will be described with reference to FIG. In the embodiment, the impeller 43 is used as the positioning member.
Although a device equipped with one impeller 43 has been described, if the difference between the diameter of the sliding body 13 and the spindle pitch is large, if you try to increase the feed amount of the sliding body 13 with one impeller 43, the adjacent sliding body 13, which causes some inconvenience. This embodiment differs greatly from the previous embodiment in that in addition to the impeller 43, an auxiliary positioning lever 56 is provided as a positioning member on the front side of the impeller 43 in the direction of movement of the doffing machine 1. The positioning lever 56 is rotatably supported by a support bracket 57 and connected via a link 60 to the tip of a swing lever 59 rotatably supported by a support shaft 58 . The swing lever 59 is equipped with a cam follower 59a that comes into contact with a cam 63 that rotates integrally with a rotating shaft 62 that is rotated via a timing belt 61 that is wound between the pulleys 53 and 54. By the action of a cam 63 that rotates in conjunction with the cam 63, it swings between a retracted position shown by a chain line and an active position shown by a solid line. The boo IJ 64 fitted on the rotating shaft 62 is formed to have a diameter of 1/2 of the pulley 54 of the impeller 43, and the diameter of the impeller 43 is 1/2.
During the /4 rotation, the cam 63 rotates 1/2, and the positioning lever 56 reciprocates once to perform the primary adjustment of the arrangement interval of the sliders 13, and then the impeller 43 moves the sliders 13 to a position corresponding to a predetermined spindle pitch. Positioned. Note that the timing belt 61 is tensioned in an optimal state by a tension boob IJ65.

Note that this invention is not limited to the above embodiments, and the number of engagements a42 of the impeller 43 may be changed or all spindles may be changed.
It may be applied to a spinning machine equipped with a Qi type doffing machine and a single-heat type machine. In that case, before operating the doffing machine, a working machine equipped with a positioning device 39 is run along the guide rail 9, and the position of the sliding body 13 is adjusted to a position corresponding to the spindle 12. Moreover, the shape of the sliding body 13 may be made into a shape other than circular, and a plurality of impellers 43 may be provided as a positioning member.

Effects of the Invention As detailed above, according to the present invention, it is possible to use the same type of sliding body even for spinning frame frames with different spindle pitches, and the manufacturing cost of the sliding body is reduced.

In addition, the structure of the positioning device for the sliding body is simplified, and since the positioning device positions the sliding body sequentially from the end while moving, the number of slides pushed by the positioning device gradually decreases, resulting in overall power consumption. This has the excellent effect of reducing the amount of
