Abstract

PURPOSE:To enable various kinds of packages to be transported to the next process in a fixed order by driving a transport conveyer along a take-up zone after roping up a set number of packages from each take-up zone. CONSTITUTION:When a winding unit UAi receiving roping-up command is detected while a roping-up truck 4 is travelling in a zone ZA, the truck 4 is stopped in that position and a wound-up package PA is delivered to a conveyer 1 by the roping-up operation. And the truck 4 again travels and reversed at a traverse end 14. In this reversal the truck passes through a zone A even in receiving the roping-up command and travels in a zone ZB to be reversed at an end 15. The truck 4 receives the roping-up command in the zone ZB to carry out the roping-up operation with the unit UBr. And various kinds of packages PB are mounted on the conveyer 1 at the downstream side of package PA and the conveyer 1 is driven toward the next process.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for doffing and conveying packages in an automatic winder.

[Conventional technology]

The package produced by the automatic winder is fed to a double twisting machine to impart twist to the yarn. Further, as the above-mentioned double yarn twisting machine, there is a type in which two packages arranged in upper and lower stages (hereinafter simply referred to as a yarn feeding package) are used as the yarn feeder, and two yarns are combined and twisted.

In such a double twisting machine, the tension of the yarn unraveled from the lower package of the yarn supply packages is higher, and the yarn is elongated. For this reason, if the amount of yarn in the yarn feeding packages is the same on the top and bottom, yarn will remain in the lower package even after the upper package is unraveled.

Therefore, in order to reduce the amount of yarn remaining in the lower package, it is common practice to supply the lower package as a package with a slightly smaller amount of yarn than the upper package.

[Problem that the invention seeks to solve]

A double yarn twisting machine using the above yarn feeding package is connected to an automatic winder in the previous process, and a preparation station is installed between the winder and the double yarn twisting machine, where the packages produced by the winder are stacked in two stages to form a yarn feeding package. When the winder is arranged in the winder, the packages with the above two types of yarn amounts need to be delivered in order.

An object of the present invention is to provide a winder doffing and conveying method that is particularly suitable for a system that connects such a winder and a double twisting machine.

[Means for solving problems]

The winder is essentially divided into two winding zones, the first
In the second winding zone, a package with a small amount of yarn is wound, and in the second winding zone, a package with a large amount of yarn is wound.
One package doffed in the first winding zone and one package doffed in the second winding zone are grouped into one group and transported in a fixed order.

〔Example〕

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

An example of an automatic winder is shown in FIGS. 5 and 6. The automatic winder (W) has many winding units (Ui
) are arranged in parallel, and along one side of the winding unit there is a conveyor belt for conveying full packages (1
) has been installed. Furthermore, the doffing cart (4
) is suspended and supported via wheels (3) (3) and moves in the directions of arrows (DA) (DB) in Fig. 5, and the trolley (4) stops at a unit position having a full package (P). An automatic doffing operation is performed to discharge the full package on the unit onto the conveyor belt (1).

In each of the above-mentioned winding units (Ui), the yarn (Y) unwound from the spinning pobbin (5) passes through a known yarn clearer (6) and is rotated by a traversing drum (7) as shown in Fig. 6. The package (P) is traversed and wound up.

When the set amount of yarn is wound by the fixed length winding mechanism installed in each unit or the winder stand, a full wind signal is emitted from the fixed length winding mechanism and the full wind lamp (8) lights up, which will be explained later. The doffing truck (4) is actuated to perform doffing according to a command from the control device.

Furthermore, in this embodiment, the automatic winder is connected to a two-stage yarn feeding type double twisting machine (10) as shown in the first figure, so that the winding unit is substantially divided into two winding zones (ZA ), (ZB), the units (Ul) to (In) constitute the zone (ZA), produce a package (PA) with a small amount of winding, and the unit (Um
) to (Ux) constitute a zone (ZB), and produce a package (PB) with a larger amount of winding than the above package (PA).

Between the weaving machine (W) and the double twisting machine (10), the zone (ZA) package (PA) and the zone (ZB) package (PB) are transported on the conveyor (1).
) is assembled into a two-stage yarn feeding package (PM) shown in FIG. 4, and a yarn feeding package changing device (11) is installed to replace the empty feeding yarn sent from the double twisting machine side.

Furthermore, a control device (12) is installed on the automatic winder side to control the operation timing of the doffing truck (4), the operation timing of the conveyor, etc., and operates in conjunction with the fixed length winding device. In addition, the automatic winder zone (
At the boundary between ZA) and zone (ZB), a boundary signal magnet (13) is installed on the travel path of the doffing truck (4), and the truck (4) detects the magnet (13). A boundary signal detection means such as a reed switch (RS) is provided.

Next, the operations of the doffing truck (4) and the conveyor (1) will be explained. In Fig. 1, while the doffing truck (4) is traveling in the direction of the arrow (DA) in the zone (ZA), the doffing truck (4) is traveling in the direction of the arrow (DA) and the winding uni-nod (U) where the doffing command is being issued.
Ai) is detected, the trolley (4
) stops, performs normal doffing motion, and completes the full package (
PA) is paid out to Conhair (1). Unit (L
After completing the doffing operation at IAi), the cart (4) again starts traveling in the direction of the arrow (DA) and reaches the traverse end (1
When the vehicle is reversed in step 4), it then starts running in the direction of the arrow (DB). While traveling in the direction of the arrow (DB) and within the zone (ZA), even if there is a winding unit with a doffing request command, it will pass without stopping, that is, without performing a doffing operation. and the boundary position (13
). Then arrow (DB) inside the zone (ZB)
Or, while the winding unit (tlB) is inverted at the end (15) and traveling in the direction of the arrow (DA), there is a doffing request.
When r) is detected, the unit stops and doffs at the relevant unit position.

When the doffing operation of the above UNISO) (UBr) is completed, there are two packages (PA) and (UBr) on the conveyor (1).
PB) is placed, and the rotating direction (1) of the con hair (1) is
A zone (ZA) package (P) is placed on the upstream side in 6).
A) Package (PB) with zone (ZB) on the downstream side
are lined up in order. By rotating the conveyor (1) in this state, a pair of packages (PA) (PB
) is conveyed on the conveyance path (1) (17) toward the package exchange device (11) on the double twisting machine side. Therefore, in the exchanging device (11), the packages transferred on the conveyors (1) and (17) are placed in the holder (1) shown in Fig. 4 in the order in which they arrive.
If you insert a package into 8), there will always be a zone (
The package (PA) for ZA) is on the top shelf, and the zone (ZB) is on the top.
) packages (PB) are located, and a desired two-stage yarn feeding package (WP) is assembled.

A pair of packages (PA) on the above Conhair (1) (
While the package (PB) is being transported, the doffing operation by the doffing truck (4) is suspended, and when the transportation of the package (PA) (PB) is completed, the next doffing operation becomes possible.

That is, the cart (4) is in the zone (ZB), the package conveyance is completed, and the cart (4) is in the zone (ZB) again.
If there is a doffing request in the zone (ZB) while traveling towards the arrow (DA) in the unit, the unit will stop at the unit concerned,
Do a doffing motion. Further, move inside the zone (ZB) with an arrow (DA).
), the doffing motion is now blocked within the zone (ZB), and when driving across the boundary (13) to the zone (
The block of doffing operation is released from the moment it enters the zone (ZA), and the doffing operation is performed in the winding unit that requests doffing within the zone (ZA). Rotation in the direction of arrow (16) of 1) is started. Therefore, in this case as well, the pair of packages (PA) and (PB) are transported while maintaining the same order as described above, and are transported toward the package exchange device (11).

An example of a control circuit for controlling the above operations is shown in FIG. In the above circuit diagram, the upper side from the dashed-dot line (19) is the control circuit (12) on the main body side of the wine ring, and the lower side is the control circuit (20) provided on the trolley (4), and the control circuit (20) installed on the main body (W) and the trolley (4). The slider cable (21) is used to send and receive signals between
).

In Figure 1.3, the contact (RA2) is closed while the truck is running, and the contact (RA2) is closed while the truck is traveling in the direction of the arrow (DA').
RAS) is located on the white circle (22) side, and when the cart crosses the boundary (13), a boundary signal is generated and the reed switch (R
3) is temporarily closed and the keep relay (KRI) is sent.

In other words, the keep relay (
KRI) is on. When the cart is reversed at the right end (14) of the zone (ZA), the contact point (12A5) becomes the black circle (2
3), but the reed switch (R3) is open, so the keep relay (KRI) remains on. Furthermore, the trolley travels in the direction of the arrow (DB>), and the border (
13), the reed switch (R3) closes temporarily and the keep relay (KRI) is turned off. Therefore, in the above circuit, the truck (4) is in the zone (ZA
), the keep relay (KRI) is on, and when it is within the zone (ZB), it is off. That is, the first keep relay (KRI) is a relay for storing the position of the truck.

Also, the second keep relay (KH2) is zone (ZA)
Doffing memory relay, 3rd keep relay (KH2)
is a zone (ZB) doffing memory relay. That is, when a doffing operation is performed in the zone (ZA), the two contact points (KRI~1) (KRI-2) both become white circles (2
4) The contact (17A9), which is switched to the (25) side and turns on only while doffing is being performed, closes, the second keep relay (KH2) is turned on, and the doffing command circuit contact ( KH2-1) opens, and the transfer command circuit contact (KH
2-2) closes.

Therefore, even if the doffing command is received from the winding unit throat side while the cart is running in the zone (ZA), the contacts (KRI-2) (KH2-1) are open and the doffing device is activated. The drive command relay (R^6) remains off, and two packages are not dispensed in the zone (ZA).

Next, when the trolley (4) crosses the boundary and enters the zone (ZB), the keep relay (KRI) is sent,
The contacts (Kl?1-1) (KRI-2) all switch to the black circle side. In this state, doffing is 1 in the zone (ZB)
When this is repeated, the keep relay (KH2) is turned on, so that the contact (KH2-1) is opened and the contact (KH2-2) is closed. Therefore, the contact of the keep relay (KH2-2) (KH
2-2) and the relay contact (PA9-2) during doffing, that is, the zone (ZA) (Z
When the doffing operation is performed once in B), the transfer command relay (PA25) is turned on. When the relay (RΔ25) is turned on, the contact (PA25-1) switches to the white circle side,
The relay (RAloo) on the main body side is turned on via the line 11) (*2) from the cart side to the main body side, a conveyance command signal is issued, and the conveyor drive motor is driven incorrectly for several seconds. That is, by interposing a delay relay between the relay (RAloo) and the conveyor drive motor, the conveyor rotates after the second doffing operation is completed.

Next, when a conveyance completion signal is issued, the relay (RA) is activated.
IOI) is turned on, the contact (RAIOI-1) switches to the white circle side, and at this time, the contact (PA25-1) has already completed the doffing operation, that is, the relay (17A9-1) is turned off, so the contact (RAIOI-1) switches to the black circle side. Therefore, the keep relay (K
The reset side of H2) (KH2) is energized, the keep relay (KH2) (KH2) is turned off, and the doffing memory is reset.

Zone (ZA) is controlled by the control circuits (12) and (20).
