Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bobbin transfer device, and particularly to a bobbin transfer device that transfers a real bobbin produced by a spinning machine onto a conveyance path of a winder.

[Prior Art] Among bobbin transfer devices, a device that does not damage the yarn layer of the actual bobbin and saves space is the “Bobbin Transfer System” (Japanese Patent Application Laid-Open No. 60-31478), which was previously proposed by the applicant. Publication No.).

As shown in FIGS. 6 and 7, this bobbin transfer device a is capable of transferring the real bobbin B transported from the spinning machine S side to the winder W side directly connected to the spinning machine S. It is located in a suitable position.

The spinning machine S has two conveyance paths b along its longitudinal direction, and for example, the spinning machine S has two conveyance paths b along its longitudinal direction.
It is designed to alternately transport every 500 pieces. Therefore, the transfer device a also has two
A table is provided. The produced actual bobbin B is inserted into a peg on a transport band forming a transport path b, and is transported in the direction of arrow c in the figure to a predetermined bobbin payout position d.

On the other hand, the winder W is formed with a conveyance path f for supplying the actual bobbin B to the winding unit e arranged in parallel and for transporting the bobbin after being wound up. That is, the real bobbin B newly inserted into the tray T is prepared for winding by the yarn end pick-up device g, and then is supplied to each winding unit e along the real bobbin supply path h.

The bobbin i or the bobbin j with residual yarn that has been wound up by the winding unit e and is now empty is conveyed along the bobbin return path k in the direction of the arrow l. Among the bobbins j with residual yarn, those that can be wound again are circulated to the actual bobbin supply path h, and the bobbins with very little residual yarn are taken out from the tray T together with the winding tube and processed separately. Further, the empty bobbin i is extracted in the same manner, and is then introduced into the chute n of the spinning frame S via the empty bobbin transport path m, and inserted into the empty peg on the transport band.

The real bobbin supply path h and the bobbin return path k are connected in a closed loop at the end facing the spinning machine S, and an empty tray standby position o for receiving the real bobbin B is provided along the way. Therefore, in addition to the empty tray from which the bobbin has been removed, the tray in which the bobbin j with residual yarn is inserted is also conveyed to the empty tray standby position o.

As shown in FIGS. 8 and 9, the bobbin transfer device a includes a guide shaft p, a lifting body q,
A bobbin chuck device r is provided. After the bobbin chuck device r extracts the real bobbin B from the peg at the bobbin discharging position d, it rotates as the elevating body q rises and rotates along the guide shaft p, and moves the real bobbin B to the empty tray standby position o. It will be transferred.

[Problems to be Solved by the Invention] By the way, the inventors of the present invention were in the process of developing a bobbin transfer device to improve the above-mentioned device a and realize smooth transfer.

That is, by forming a rotating arm having a length that allows the actual bobbin B to be delivered from either of the two conveyance paths b of the spinning machine S, and by rotating and raising and lowering it as appropriate, the The real bobbin held by the holding means is transferred. With this configuration, one transfer device can handle one
The real bobbin B is transferred to the empty tray standby position o, which facilitates interlocking with the spinning machine S, and by adjusting the rotation speed, etc., the transfer efficiency can be improved.

However, the empty tray T is moved to the empty tray standby position.
There was a problem in having them lined up one after another and waiting when they were being transported.

As shown in FIG. 10, when the swing arm intersects the conveyance path f on the upstream side while swinging to the empty tray standby position o, there is a problem if the tray T at the crossing position s is an empty tray. However, if the tray T has a bobbin j with residual yarn, the real bobbin B that is being transferred will come into contact with it, and there is a risk that the bobbin or the transfer device will be damaged.

To prevent this, the empty tray standby position
A tray detection sensor t is provided on the upstream side of the conveyance at a predetermined distance from It is conceivable to control so that the tray T does not exist at the crossing position s by stopping the tray T. However, in this case, after the transfer is completed, the conveyance stop will be canceled and the next tray will be conveyed from the upstream side of the intersection position s.
This will cause a delay in the transfer.

In addition, if you try to relocate the standby position o to a position that does not intersect with the rotation, or if you try to circulate the bobbin j with residual thread to the actual bobbin supply path h using another conveyance path, the conventional bobbin conveyance path There is no choice but to make a major design change to f.

Therefore, the present invention was devised to provide a bobbin transfer device in which the actual bobbin during transfer does not come into contact with the bobbin with residual yarn, and in addition, there is no transfer stagnation or change in the design of the conveyance path. be.

[Means for Solving the Problems] The present invention includes a gripping means for gripping the head of the real bobbin in order to transfer the real bobbin from the spinning machine to the empty tray waiting on the bobbin transport path of the winder;
The bobbin transfer device has a swing arm that swings the gripping means across the bobbin transport path upstream of the standby position, and the bobbin transfer device is provided on the swing axis of the swing arm and swings in synchronization with the swing arm. The cover member engages with the bobbin with residual yarn that is conveyed through the bobbin conveyance path while being inserted in the tray, and pushes it away from the position where it intersects with the orbit of the gripping means.

[Operation] With the above configuration, the gripping means that grips the actual bobbin pivots to the position where the empty tray waits according to the pivot arm. The cover member moves in synchronization with this turning, and when a bobbin with residual thread crosses the turning trajectory, it is pushed away from the intersecting position and prevents it from coming into contact with the actual bobbin.

[Example] An example of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show an embodiment of the bobbin transfer device according to the present invention, in which a real bobbin B is installed between a winder W and a spinning frame S so that a real bobbin B can be transferred. It shows.

This device includes a vertical shaft 2 which is provided in a housing 1 so as to be rotatable around the axis, an elevating body 3 which is provided on the vertical shaft 2 so as to be movable up and down, and a radially outer side of the elevating body 3. a rotating arm 4 provided on the side;
A gripping means 5 provided on the swivel arm 4 for gripping the head of the real bobbin B, and a gripping means 5 provided on the swivel arm 4 for gripping the head of the real bobbin B, and a gripping means 5 for gripping the head of the real bobbin B, and a gripping means 5 for rotating the swivel arm 4 as appropriate
and a cover member 7 which is a feature of the present invention.
is provided so as to cover the gripping means 5.

The gripping means 5 is formed to grip and release the real bobbin by supplying or discharging compressed air, and is activated when it is appropriately lowered at the real bobbin payout position 8 and the empty tray standby position 9. It's becoming like that.

The elevating body 3 is rotated integrally with the vertical shaft 2, and has a vertical arm 1 suspended in parallel with the vertical shaft 2.
0, and a swing arm 4 is connected to this lower end. Therefore, the pivot arm 4 is pivoted about the vertical axis 2 as the pivot axis.

The drive means 6 includes a main drive shaft 12 rotated by a motor 11 serving as a drive source, a swing drive unit 15 that sequentially transmits driving force from two cams 13 and 14 fixed to the main drive shaft 12, and an elevation drive system. It consists of 16.

A crank mechanism is formed in the swing drive system 15, and the vertical shaft 2 is rotated by a predetermined angle α by a lever (not shown) provided by a cam 13. Therefore, this rotation causes the elevating body 3 and the vertical arm 1 to
0, and is transmitted as a rotation drawing a trajectory A connecting the actual bobbin payout position 8 of the rotation arm 4 and the gripping means 5 and the empty tray standby position 9.

A link mechanism is formed in the elevating drive system 16, and the elevating body 3 is moved up and down within a predetermined range by means of another lever (not shown) that is swung by the cam 14. Therefore, this lifting and lowering is performed by the gripping means 5.
Then, the actual bobbin B is gripped/released, extracted from the transport band 17, and inserted into the empty tray T.

Further, the vertical shaft 2 is equipped with a rotation switching means 18, which corresponds to the switching of the conveyance path of the spinning machine S.
The rotation range of the vertical axis 2 is changed.
With this, for example, the swing arm 4 can switch from swinging from one bobbin discharging position 8 to the empty bobbin waiting position 9 in FIG. 1 to pivoting from the other bobbin discharging position 19. .

The cover member 7 is provided at a position radially outward of the real bobbin B to be gripped, covers approximately 1/4 of the side of the entire circumference, and is configured so that the outer wall 20 draws an appropriate curved surface. It is formed in the shape of a vertically divided cylinder. The upper end thereof is connected to the vertical arm 10 via a mounting arm 21 arranged above and in parallel with the swing arm 4. That is, like the pivot arm 4, it is adapted to be moved around the vertical axis 2 and along the axial direction. In this example,
In terms of turning when the winder W crosses the bobbin transport path 22, it is located in front of the gripping means 5 in the turning direction. In other words, the intersecting position 23 is reached before the gripping means 5 and the real bobbin B.

Therefore, the cover member 7 engages with the bobbin 24 with residual yarn that is conveyed through the bobbin conveyance path 22 while being inserted into the tray T, and pushes it away from the position 23 where it intersects with the orbit A of the gripping means 5. It's becoming like that.

Note that a bobbin sensor 25 is provided at the empty tray standby position 9 of the winder W to determine whether or not the waiting tray T has a bobbin 24 with residual thread. In some cases, a signal is sent to a transport control means (not shown) to allow the transport to pass through.

Next, the operation of this embodiment will be explained.

The real bobbin B is placed at the real bobbin payout position 8 of the spinning machine S.
When there is an empty tray T in the empty tray standby position 9 of the winder W, the bobbin transfer device is activated and the real bobbin B is transferred.

The pivoting arm 4 has a predetermined angle α, for example approximately 116
The robot is rotated by a certain degree, and is raised and lowered at a predetermined timing along with this rotation. When the gripping means 5 is lowered at the actual bobbin discharging position 8, the gripping means 5 holds the actual bobbin B.
Grasp the head of. After that, it rises and turns to reach above the empty tray standby position 9, and then is lowered to be inserted into the tray T and released from the grip.

As shown in FIG. 1, when the bobbin 24 with residual yarn that has been conveyed together with the empty tray T to the intersection position 23 is inserted into the tray, the cover member 20 will cause the remaining yarn to remain on its curved outer wall 20. The threaded bobbin 24 is pushed to the upstream side of the conveyance to avoid contact with the real bobbin B which is gripped and rotated.

When the empty tray T exists at the intersection position 23, the cover member 7 and the real bobbin B pass above it. Furthermore, when turning from the other actual bobbin cut-out position 19, since it does not intersect with the conveyance path 22, the transfer is the same as in the conventional case.

In this way, since the actual bobbin B which is being rotated is cut off from the bobbin 24 with residual yarn, the gripping means 5 and the like of the transfer device are not damaged due to contact. Further, even if the tray T is located at the intersection position 23, there is no problem with transfer, so complicated conveyance control is not required, and the efficiency of supplying actual bobbins is improved. Furthermore, since the structure is simple and can be easily applied to conventional transfer devices without changing the bobbin transport path 22, it is highly versatile.

In the present embodiment, the cover member 7 is illustrated as covering the side portion of the real bobbin B almost entirely over its longitudinal direction, but the bobbin 24 with residual thread can be inserted therein. It may be partially covered as long as it is done so. and mounting arm 2
1 may be located below the pivot arm 4. Furthermore, it is also possible to attach the cover member 20 directly to the swing arm 4 or the gripping means 5 without using the mounting arm 21;
It is necessary to devise a configuration that does not affect the turning movement of the machine. Naturally, the outer wall 20 needs to be made of a smooth material that will not damage the yarn layer of the bobbin 24 with residual yarn during insertion.

Next, another embodiment will be described.

3 to 5 show that after the gripping means 5 inserts the real bobbin B into the waiting empty tray T and returns to the spinning machine S side, the bobbin 24 with residual yarn is placed at the crossing position 23. It is configured assuming that such a problem exists, and countermeasures have been added. For example, this case corresponds to the case where the bobbin 24 with remaining yarn is transported immediately after the actual bobbin B has passed through the rotation.

The cover member 26 shown in FIG. 3 is formed to cover the outer radial direction of the gripping means 5 over almost the entire circumference, and similarly to when gripping the real bobbin B, Even when the rotation returns, the bobbin 24 with remaining yarn is inserted to the upstream side of the conveyance.

The cover member 27 shown in FIG. 4 is connected to the mounting arm 21 by a hinge 28, and is driven so that the gripping means 5 passes above the bobbin 24 with residual thread when turning back (descending). At the same time, the inner wall 32 of the cover member 27 is pushed by the bobbin 24 with residual yarn and is expanded outward. In this case, it is desirable to attach a spring 29 so that after passing the crossing position 23, the spring 29 is quickly returned to the original position.

The cover member 30 in FIG. 5 is formed with a portion 31 extending along the radial direction of the orbit A, and the gripping means 5 is located at the empty tray standby position rather than at the intersection position 23. When it is on the 9 side, the bobbin 24 with remaining thread is not allowed to enter the crossing position 23. In this case, the extending portion 31 may have any shape as long as it can block the bobbin 24 with residual yarn.

[Effects of the Invention] In summary, the present invention provides the following excellent effects.

(1) A cover member is provided that moves in synchronization with the rotating arm and pushes the bobbin with remaining thread away from the position where it intersects with the rotation trajectory of the gripping means, so that movement caused by the actual bobbin coming into contact with the bobbin with remaining thread is prevented. Damage to the mounting device, bobbin, etc. is prevented.

(2) Since it is possible to transfer regardless of the presence or absence of trays at the intersecting position, there is no need for complicated tray conveyance control and the transfer efficiency can be improved.
