Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a doffing package processing device in an automatic winder.

[0002]

[Prior Art]

 In an automatic winder in which a large number of winding units are arranged side by side, the full package wound by each winding unit is removed from the unit and delivered onto a package conveyor laid along the winding unit.

The above-mentioned package conveyor is driven at a certain time interval in relation to the time when one package is fully wound, and at the end of the conveyor, an operator packs the transferred package in a box. The doffed full-roll package is being transported by being transferred to a carrier or automatically transferred to a subsequent automatic carrier line.

[0004]

[Problems to be solved by the device]

 In the above system, the driving of the package conveyer is set so that it is performed at an interval approximately equal to the winding time of one package. Therefore, for example, in a winder equipped with winding units of 60 weights, Ne40 If the time for winding the cotton thread to the set length is about one hour, the number of packages produced in one hour is not necessarily 60, but 60 or less. However, since the package transfer conveyor is driven every set time, the amount of packages transferred on the conveyor is irregular. Therefore, it may cause irregular changes in the packaging process in the later process.

Further, it is necessary to set the drive time of the package transfer conveyor again according to the type of yarn to be rewound, the amount of wound yarn, the efficiency of the winder, and the like.

The present invention solves the above problems and provides an apparatus capable of efficiently performing package processing.

[0007]

[Means for Solving the Problems]

 In the present invention, a winder having a large number of winding units arranged in parallel is provided with means for detecting the number of full winding packages produced by each winding unit, and the number of full winding packages produced by the winder reaches a set number. In some cases, the doffed full-package transfer conveyor is driven.

【Example】

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

In FIG. 3, (W) is an automatic winder composed of a plurality of winding units (U) arranged in a direction perpendicular to the plane of the drawing, and each unit (U) is drawn from a supply bobbin (B). Various mechanisms such as a slab catcher, a yarn splicing device, and a traverse drum (1) for winding a predetermined amount of a predetermined amount of the yarn into a package (P) having a predetermined shape are provided.

On one side of the winding unit, a conveyor belt (2) for conveying a full-wrapped package is laid along the unit.

An inclined guide plate (4) for guiding a package removed from the cradle (3) onto the conveyor is provided between the cradle part (3) of each unit and the conveyor (2). Further, a stock device (5) for temporarily stopping the package rolling on the guide plate is provided. The stock device (5) extends along the whole unit, and a stock lever (6) and a support lever (supporting the stock bar (6) and swivelable around a shaft (8) by a fluid cylinder (7) ( 9) etc.

Therefore, when the stock bar (6) is in the position indicated by the solid line, the doffed packages in each unit come into contact with the stock bar (6) and are stopped and stocked in the middle of the guide plate (4). When the (6) moves to the position indicated by the chain double-dashed line (6a), the stocked package (P1) is rotatably transferred onto the conveyor (2) and the conveyor (2) is rotated to winder. It is designed to be transported toward the end of the. The stock bar (6) prevents the doffed package from colliding with the package being conveyed while the conveyor is being driven.

Incidentally, (10) of FIG. 3 is a dolly having an automatic doffing device, which travels via wheels (12) on a ceiling rail (11) laid in the longitudinal direction along the winding unit (U). At the same time, it stops at the unit position that issues a full winding signal and a series of doffing operations are performed. Further, (13) is a magazine that stores spinning bobbins, and when a plurality of bobbins (B) at the rewinding position are dispensed while one bobbin in the magazine is dispensed, one bobbin in the magazine is wound on the unit. It is supplied to the return position. The present invention is also applicable to a winder of the type that directly supplies a bobbin from the bobbin transport path to the rewind position of each unit without having the magazine.

In such a winder, a constant length winding device for making the yarn length and the yarn amount of a package to be produced constant is constituted by a device as shown in FIG. 2, for example. That is, the traverse drum (1) installed in each winding unit is directly driven by the motor (14) installed in each unit, and the motor (14) is driven by the drive switch (16) from the power supply (15). Drive power is supplied through the drive. The drive switch (16) is closed during normal winding to drive the motor, but if yarn breakage occurs, the switch (16) opens due to the yarn absence signal of the yarn detecting means provided in the yarn path of the unit, The program (1) stops immediately and the winding of the yarn is stopped.

A magnet (17) is embedded in an end portion of the traverse drum (1), and a sensor (18) provided close to the magnet (17) is provided for each rotation of the drum (1). , Detects a magnet and generates a pulse signal. The pulse signal (L1) generated by the sensor (18) is input to the constant length winding device (19). In the constant length winding device (19), the pulse signal (L1) input (20) is counted (24), and the count number, that is, the set yarn length, that has been input (25) to the memory (21) in advance is reached. Then, the full winding signal (23) is output through the output interface (22). The relay (26) is excited by the signal (23), the switch (16) is turned off, the drum drive motor (14) is stopped, and the full-winding indicator lamp (27) provided in the unit lights up. It is designed to display the lift command.

Further, in FIG. 1, the full winding signal (23) output from the constant length winding device (19) is input to the doffing counter (28). The doffing counter (28) inputs the full winding signal (23) generated from the constant length winding device (19) through the line (29), accumulates the count, and when the count is preset, It outputs signals (31) (32) for driving the fluid cylinder (7) for operating the stock bar (6) and the motor (30) for driving the package conveyor (2). The count value set in the doffing counter (28) is preferably set to a value smaller than the number of winding units that make up the winder. That is, when the value is set to be larger than the number of units, two or more full packages in one unit may be accumulated on the guide plate (4) in Fig. 3, and the yarn layer surfaces of the packages contact each other. This is because if the length of the guide plate (4) is suitable for one package, the doffing operation in the unit may be disabled. However, if the length and space between the stock bar (6) and the cradle part (3) are sufficient, the set value of the counter (28) is not limited to the range of the number of winding units. .

The operation of the above device will be described below.

FIG. 4 and FIG. 5 are schematic diagrams showing a doffing process for a full-roll package.

Normal winding is performed in each winding unit (Ul) to (Un), and when the constant length winding device (19) detects full winding in, for example, the unit (Ul), as shown in FIG. The drum (1) is stopped by the full winding signal and the full winding display lamp (27) is turned on. Further, the full winding signal (23) is input to the doffing counter (28) in FIG. 1 and the count "1" is stored in memory.

When the doffing trolley (10) of FIG. 3 is running and the lamp (27) is detected by turning on the full-winding indicator lamp (27), the unit is stopped and the doffing operation is performed. Each full-wrapped package is removed from the cradle (3), discharged onto the guide plate (4) in FIG. 3, and temporarily stopped and stocked at the position where it abuts on the stopper (6).

In this way, as shown in FIG. 4, the full roll packages (P1) to (Pn) are successively stocked at the position of the stock bar (6), and in the meantime, the counter (28) is continuously loaded with full rolls. When the number of packages is stored in the coefficient memory and the count number matches the set number, the package transfer command signals (31) (32) in Fig. 1 are output, and at the same time, the working fluid cylinder (7) of the stock bar (6) is output. ) Works. Therefore, as shown in FIG. 5, a predetermined number of packages (Pl) to (Pn) at the stock bar position are simultaneously delivered onto the conveyor (2) and driven by the conveyor in the direction of the arrow (33) in FIG. That is, it is conveyed toward the end of the winder. At one end of the winder, an operator loads the packages that are being transported one after another onto a trolley, or a transfer operation for automatic transportation to another processing station is performed.

When the processing of the predetermined number of packages on the conveyor (2) is completed in this way, the rotation of the conveyor (2) is stopped and the package is ready for the next package conveyance.

The counter (28) is reset at the same timing as the operation of the stock bar (6) or the operation of the conveyor drive motor (30).

In this way, the amount of packages transferred and processed by one operation of the package transfer conveyor (2) becomes constant. That is, even if the winding time varies depending on the type of yarn to be processed, the amount of package transferred by one operation of the conveyor is constant.

In the above embodiment, an example in which the number of full-roll packages is counted by the full-roll signal output from the constant length winding device (19) has been described, but another method, for example, one winder can be used. The number of doffing operations of the automatic doffing trolley (10), that is, if doffing is completed by one rotation of the cam shaft of the doffing mechanism provided in the trolley, for example, once every one rotation of the cam shaft. The number of full-wrapped packages can also be counted by providing a limit switch that operates once and counting the signal generated by turning on the switch.

[Effect of the device]

 As described above, in the present invention, the number of packages conveyed by one conveying operation of the full-winding package conveyer laid along the winder is always constant, and even when the type of yarn in progress is changed. Since a fixed number of packages can always be transferred for each conveyor operation, subsequent box packing or package supply to the loom, warper, etc. is quantified by group, and package management becomes easy.
