Description

[Detailed description of the invention] The present invention relates to a doffing device in an automatic winder.

In an automatic winder consisting of a large number of winding units lined up, a conveyor is installed at the back of the unit that automatically doffs full packages that have reached a set amount or length. The applicant previously proposed a device for transferring onto the surface. That is, Japanese Patent Application Laid-Open No. 56-132269 (as shown in Figure 2, the cage is placed on the cradle arm and placed on the cradle arm pair), and the device car for storing or transporting the cage is used. be.

In such a device, even if the word "two-man roll" is issued, it may not be doffed.

In other words, if a new full package is listed even though a full package has already been placed on the conveyor belt, the new package will be blocked by the package already placed on the conveyor belt. , h, not only could it not be placed on the conveyor, but it also interfered with the next winding.
A place to automatically transport a full volume of Basoguge by rotating the Koni/Bear.

In this case, if a certain take-up unit doffs while the container is rotating, that is, while a fully wound cane is being transported, the doffed full package will collide with the package being transported. Even if the package is transferred unloaded accidentally due to a collision, the posture of the package will collapse and the subsequent process will be hindered. It takes time for the long conveyor that runs along the multiple units to rotate and the packages on the conveyor are ejected from the automatic wine goo, and it is extremely inconvenient for the wine goo's operating efficiency to stop the doffing operation during this time. It is.

The purpose of the present invention is to reduce the above-mentioned various inconveniences by %YR, and it extends beyond each unit of a mechanical winding machine in which a large number of winding units are arranged side by side, and a fully wound package is placed thereon. A guide path for the dead pano boon is arranged between the moving down transport conveyor and the position where the full package leaves the cradle part of each winding unit, and a stock member is provided to temporarily stop the full package at the middle of the guide path. This is installed on the above guide route.

Embodiments of the present invention will now be described with reference to the drawings.

Figure 1 (= where W is an automatic winder with a large number of winding units arranged in parallel in the direction perpendicular to the paper) (each unit (U) i2 supports a winding package (1) It is equipped with a cradle part (2) that rotates the package while traversing the yarn, a traversing drum (3) that contacts and rotates the package while traversing the yarn, or a magazine (4) that stores a plurality of yarns. or will be done.

At the back of the unit, that is, when the yarn running path side is the front side, a full package transport conveyor belt (5) is disposed extending from the unit at 16-), and is arranged at each unit position of the conveyor. A guide path (6) is formed by a bottom plate (7) and a side plate (8) for guiding a full package detached from the cradle part (2) from the detachment position to the conveyor belt.

The guide path (6) is inclined slightly toward the conveyor (5) side, and has an inclination angle U sufficient for the full-volume ζ cage detached from the cradle part (2) to roll under its own weight.

It should be noted that the guide line ('l) fixed along the side of the conveyor belt (5) extends across the whole unit (2') and transfers over the guideway (6) to the conveyor belt (5).
- It has the role of controlling the posture of the nokuso cage placed on the body, and it has the role of controlling the posture of the nokuso cage placed on the body.
When the sobuge collides, the axis of the screw cage is struck by the rebound, and the axis of the screw cage is semi-aligned with the direction of rotation of the conveyor.While the screw cage is being conveyed, the thread layer outer bending of the screw cage is Gaitono<-(9) is in a non-contact position (=installed and fixed.

Furthermore, a stock NS device (10) for temporarily stopping the full package leaving the crater section is installed at the end of the guide path (6). 1υ) supports all units with the stock bar (11) and the stock bar (11) at appropriate intervals by valves (12), and fixes itself to the machine frame (13). a support bar (15) supported by a bearing (14), and a fluid cylinder (16) for rotating the stock bar provided near both longitudinal ends of the soi 2/goo.
) and (2 yo 1) are constructed. That is, in FIGS. 2 and 3, the connecting rod (19) connected to the piston rod (18) of the ηC cylinder (16) which is pivotally supported (17) on the machine frame (13) has a A lever (20) pivotable around a support bar (15) or a support bar (15) is pivotally mounted, and a lever (11) is attached to the tip of the support bar (20).
Therefore, by actuation of the fluid cylinder (16), the tension lever (11) can be positioned between the solid line position in FIG. be.

Further, the stock bar (11) is provided at a position where the circular arc locus (21) centered on the stock bar (11) passes through the IJ inside the package (1b) stopped by the straight lever (11).

That is, the mounting height of the bearing (14) to the machine frame (13) is adjusted according to the size of the full package (11), and the piston rod (two connecting rods (19)) are arranged with different lengths. By replacing the rod with the above stock bar (
11] position adjustment is performed.

In other words, if the contact position between the stock bar (11) and the pack-9 (1bJ) is spaced downward, the length of the lever (20) will become longer, and therefore the turning radius will become larger and there is a risk of hitting the packages on the conveyor (5). Therefore, the guide path (6) must be made longer, which is a waste of space.

Furthermore, if the abutting position between the stock bar (11) and the package (1b) is too high, the bag may get under the stock bar and the surface of the yarn layer of the package may be damaged. ) and the package are conveniently in contact with each other in the above-mentioned position.

Furthermore, the length L) of the system internal path (6) is located between the cradle part release position (1a) of the full package and the conveyor (1a).
5) Pap-i, /(1a>(
Without interfering with IC), both pappuji (1a)
At least one full package can exist between C) and includes a distance sufficient to prevent the stock bar (11) from interfering with the package (1c) on the conveyor (5) when the stock bar (old) rotates. The length is advantageous.

In addition, doffing of each of the above units will be carried out on the 11 running lines shown in Figure 1 (starting from February 1st. In other words, the doffing will be carried out on the 11 lines shown in Figure 1. In other words, the doffing will be carried out on the ceiling rail (23) cut and laid on Uniso 1 above the unit.
) is suspended from the running body (22) or single @ (24) (24), and the full package (1) is suspended from the cradle part (2
), the empty bobbin stored in the traveling body (22) is supplied to the cradle section and winding is performed again.

Next, the operation of the device of the present invention will be explained.

In Figures 4 to 6, each winding 22) (Ul) to (U
When winding is performed in step n) and a certain amount of yarn layer is formed, the full package is separated from the cradle part by the doffing operation described above, and the package dropped onto the guide path (6) is moved to the guide path. Due to the slope of (6), it rolls under its own weight,
It rolls to the stock bar (11) position and stops at that position.

FIG. 4 is a plan view showing the state of the stocked packages after a certain period of time after the start of winding. ) is stocked on top.

In each winding unit, there is a difference in the time required to complete the winding due to various causes such as thread breakage, number of untied threads, etc., and this causes a difference in doffing time, resulting in a situation as shown in FIG. 4.

Now, for example, if the time required to form a full package (one is 60 minutes on average), the opening time interval of the stock bar (
1) is set in the relationship t<, T (for example, t = 50 minutes), and using a timer, the fluid cylinder (16) in Fig. 2 is set.
is set to run every 50 minutes.

Figure 5 shows the bag stocked in the state shown in Figure 4 - i)
(Pi) to (Pn) are discharged all at once onto the conveyor (5) by opening the stock bar (11),
The fluid cylinder (16) shown in the second figure operates, and the stock bar (11) pivots to the two-dot chain line position (11a), thereby causing the stocked packages (PI) to (J
'n) further rolls on the inclined guide path (6) and is discharged onto the conveyor (5), collides with the guide bar (9), rebounds, and changes the direction of rotation of the conveyor (5) and the axis of the package.
They are placed on the conveyor (5) so that they are parallel to each other.

Incidentally, the guide plate (25) supporting the conveyor (5) is formed with inclined surfaces (26) (27) extending from both side edges toward the center, so that the pan cage can be positioned at the center of the conveyor.

Therefore, the doffed packages do not roll all at once from the release position from the cradle onto the conveyor, but are temporarily stopped and stocked by the intermediate stock bar (11), causing the packages to collide with the stock bar (9). In the case of a cone package, which tends to meander more easily than the nut's package shown in the figure, the posture of the cone package can be controlled using the stock bar (11), allowing smooth discharge of the cone package into the guide path (6). 〇The packages (P 1 ) to (Pn) that have been systematically delivered onto the conveyor (5) can be conveyed manually or automatically.
・The drive switch of the bear was blown, and the arrow in Figure 5 (28
The conveyor (5) rotates in the direction of the pan cage (Pi).
~(Pn) are transferred, and a worker stores the packages one by one in a box at the end of the conveyor, or if a further package conveyance path is provided, the conveyance is restricted.

While the conveyor (5) is rotating, the stock bar (11) returns to its original position (solid line position in Figure 2) as shown in Figure 6, and the packages (P r
) to stock.

A time chart of the above operation is shown in FIG.

Taking the winding time axis (5) and the opening time axis CB of the stocker (11) as the horizontal axis, each winding unit (Ul) to (U
The solid line (C) in 5) indicates the time during winding, and the doffing operation is performed in the gap (S) between the solid lines, and the doffed full packages are stocked on the guide path (6). The time during which the image is displayed is indicated by a dashed line (r).

For example, in the winding unit (Ul), winding is started, the winding becomes full after a time (T), the doffing operation is performed during the time (S) after the full winding signal is issued, and the winding is started again. will be resumed.

The doffed packages are placed at the stocker on the guideway (1
1), the stock is stocked for a time (r), and at the opening time of the stock bar (IL2/2), the stock is released and discharged onto the conveyor.

The same goes for other units, but since the doffing time differs for each unit, the time (r) for which full packages are stocked on the guideway depends on each unit.
Also, in each unit, although it differs depending on the doffing time and the opening time of the stock bar, two or more full packages are never stocked on the guide path in the same unit. That is, since the opening time interval (1) of the stock par (11) is smaller than the time (T) required for a full roll, more than one doffing will not occur at the time (t) l'E. It is.

Therefore, if the automatic mill winder 11LQ is 60
Assume that the unit is composed of units, and the full winding time (T) is 60.
minutes, the opening time interval (1) of the stock bar (11) is 50
Every 50 minutes, the stocker (11) is opened and 50 to 60 full packages are discharged onto the conveyor (5) and conveyed.

In the above embodiment, the stock member is a stock bar that passes through all the units, but for example, a slit is formed in the middle of the guide road surface, and a plate that appears and retracts onto the guide road surface through the slit is inserted along all the units. It is also possible to operate one device in the same manner as in the previous embodiment using a driving source such as a fluid cylinder.

Furthermore, the above stock bar is cut into multiple units,
By providing a drive source that operates each stocker separately, packages of different types, numbers, colors, etc., can be delivered onto the conveyor without being mixed.

In other words, one automatic winder is divided into sections each having a plurality of units, and in a winder that winds different types of yarn at the valley winder, the above-mentioned stockper is provided and operated independently for each valley section, thereby achieving equal rights. By discharging several packages onto a single conveyor, it is possible to transport different types of packages without mixing them up.

As described above, the present invention includes a transport conveyor that extends along each unit of an automatic twinter in which a large number of winding units are arranged side by side, and that carries a full package and moves it, and a transport conveyor that carries a full package from the cradle of each winding unit. A guide path for the pan cage is provided between the positions where the rolled package leaves the package, and a stock member is arranged to temporarily stop the full package at the middle of the guide path, so that the full package doffed from the cradle gls is temporarily filled with the stock pigment. Since it is stocked at the location and discharged onto the conveyor at regular intervals, it is not directly discharged from each unit onto the conveyor.
Therefore, there is no need to collide with packages already placed on the conveyor, or to stop the automatic doffing device while the conveyor is rotating, increasing the operating efficiency of the doffing device and the winder's winding efficiency. It is particularly effective in automatic wine machines with automatic doffing devices, and furthermore, it is necessary to transfer the full package onto the conveyor in contact with the cradle section, so that the remaining packages are not transferred to the cradle section after stopping once again. This has various effects such as being able to prevent damage or deformation of the surface of the softened yarn layer that is transferred along the guide path and onto the conveyor.
