Abstract

PURPOSE:To dispense with an extremely large automatic thread end leading unit and respond to change in shapes and forms of thread feed packages as well as frequent change of lots by providing a continuously-arranged thread end leading unit at a suction blower actuated by manually, at a proper position of a transfer conveyor at the rear of a machine base. CONSTITUTION:When a thread end is wound at an upper end of a peg tray T three or four times and left in a hole to finish preparation of package, an operator descends a handle 19 to open a cover 17 at the upper part of a suction pipe 14 and to make the iron piece 20 of a lever 16 come close to a proximity switch 21 to energize it. Then a suction blower communicated with a suction pipe 13 starts to rotate and the thread end on the peg tray T is sucked in a core. After the termination of the thread end leading work, the operator raises the handle 19 to stop the suction blower and descends manually the stopper 224 of a swing arm 23 energized counterclockwise by a spring 25 to move a thread feed package E to a position D.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention [Field of Industrial Application] The present invention relates to a device for conveying a yarn supply package to a yarn doubling machine.

[Conventional technology]

Conventionally, the yarn feeding package has been fed to the yarn doubling machine by hand by an operator, and there has been no device that can do this automatically.

Therefore, Ganjin Toyama separately developed an automatic transport device as shown in Figure 1. In addition, the symbols A, B, C, D, E in the figure
each represents the position on each conveyor of the yarn doubling machine, and also represents the yarn feeding loose cane existing at that position.

The device is equipped with a carry-out conveyor 3 and a supply conveyor 4 along the front and rear surfaces of the machine, respectively, and two conveyors 1 and 2 lined up on the left and right on the side of each weight, divided into front and back.
A series of conveyors from the supply conveyor 4 to the discharge conveyor 3 are tilted toward the front of the machine base, and the conveyor 1 in front of each spindle side is set as the winding position, and the yarn feeding package B is placed there.
When received, they are tilted with their centers facing down.

Each yarn pulled out from the two yarn supply packages B at position B passes through the tensor part 5 and reaches the winding part 6.
The rolled package, which was wound up there and became a full tube,
It is discharged onto the conveyor 7.

When the yarn supply package B is fully wound, it is discharged to the end of the machine by the discharge conveyor 3 in the state of an empty tray A. Yarn supply packages C and D are on standby, and yarn supply package E is conveyed from the end of the machine by the supply conveyor 4 and enters position D when there are no more packages at position D. It is something. The yarn end of this yarn feeding package E has already been pulled out by the automatic pulling out device, and the yarn end has already been pulled out from the peg tray T.
The yarn is delivered wrapped several times around a hollow tube with the end of the yarn hanging inside.

The receiving and discharging of the yarn feeding packages from each of these conveyors is performed by a swing arm (not shown) whose front end is lowered by the weight of the tray and whose rear end is raised to the path of the subsequent tray.

In addition, 8 is a control box of the yarn doubling machine, and 9 is a fluff collecting device.

[Problem to be solved by the invention]

In the above-mentioned apparatus, as described above, the yarn supply package E is conveyed by the supply conveyor 4 with the yarn end pulled out by the automatic pickup device.

However, in the following cases, there is not much merit in installing an automatic pick-out device.

There is not enough space to install an automatic pick-out device that is 3 to 4 meters long.

■Lots of cotton yarn, woolen yarn, polyester/cotton blend yarn, filament yarn, etc. change frequently.

■There are various forms of yarn feeding packages, such as 3°30' and 5°57' paper tube cones, 5 inch woodwind cheeses, etc.

In such a case, rather than using an automatic feeding device, when the yarn feeding packages at positions C and D run out, the operator manually feeds the yarn feeding packages at position E and supplies them to the CSD position. Sometimes it's better to do something.

Furthermore, this operation is not necessary frequently and can be carried out when the yarn supply package runs out or when the operator has time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a yarn feeding package conveyance device for a yarn doubling machine that does not require an automatic pick-up device.

Structure of the Invention [Means for Solving the Problem] In order to achieve the above object, the yarn feeding package conveying device in the yarn doubling machine of the present invention includes a conveyor for conveying around the machine base, and a conveyor for each spindle. It has weight side conveyors lined up in two rows on the left and right on the side, and a yarn end pulling device connected to a manually operated suction blower is installed at an appropriate location on the conveyor at the rear of the machine. .

[For production]

In the yarn feeding package conveying device of the yarn doubling machine configured as described above, when an operator discovers that there is no yarn feeding package at the standby position of each spindle side conveyor, the yarn feeding package is carried by the conveyor. In the tray that comes with
The yarn supply package is inserted by the operator, and the suction blower is manually activated to take out the yarn end.

〔Example〕

The embodiment will be explained with reference to FIGS. 2 and 3.

In the one shown in FIG. 2, the supply conveyor 4 shown in FIG. 1 is not present, and instead, an empty peg tray conveyor 3 is circulated around the machine.

The symbols ASB, C, D, and E used in each figure are
As in FIG. 1, each position on the conveyor of the yarn doubling machine is shown, and the yarn supply package existing at that position is also shown.

In the depth direction of the drawing, a plurality of doubling parts are arranged in parallel, and a weight side front conveyor 1 and a weight side rear conveyor 2 are installed on the sides of each weight, which are inclined 5 inches with respect to the floor surface. has been done.

In addition, as mentioned above, there is a conveyor 3 around the machine base.
is patrolling.

On the weight side front conveyor 1 and the weight side rear conveyor 2, yarn feeding packages B, C, and D are placed in two rows, respectively.

Winding is performed at position B. Two yarn feeding packages B
Each of the threads pulled out passes through a tensor part 5 and reaches a winding section 6, where the winding package, which has been wound into a full tube, is discharged onto a conveyor 7.

The tray that is completely wound up at position B, becomes empty, and is ejected to position A, travels around the machine base and arrives at position E.

Yarn supply packages C and D are on standby.

Since the conveyors 1.2.3 of this device are tilted at the same angle toward the front of the machine, the peg trays of the yarn feeding packages A to E have the same inclination and flow smoothly.

The weight side front conveyor 1 is separated from the weight side rear conveyor 2, and the weight side front conveyor 1 is such that the two rows of conveyors for each weight can each be tilted downward toward the center.

The receiving and discharging of the yarn feeding packages from each of these conveyors is performed by a swing arm (not shown) whose front end is lowered by the weight of the tray and whose rear end is raised to the path of the subsequent tray. In this invention, since the swing arm is not made of wood, detailed explanation will be omitted.

In addition, 8 is a control box of the yarn doubling machine, and 9 is a fluff collecting device.

The operator goes around the machine stand, removes the bobbin from the empty tray at position E, and inserts a new yarn supply package into the tray. Then, take out the yarn end of the yarn feeding package, wrap it around the upper end of the peg tray 3 to 4 times, and insert the yarn end into the hole therein. Continuing, weight side conveyor 1,
The picking operation is performed by a manual picking device provided at the lower part of the conveyor 3 at the rear of the conveyor 2.

Here, the manual pick-out device will be explained with reference to FIG.

A guide plate 11 that constitutes a part of the transport conveyor 3 is attached to the boss lO of the machine base. A round belt 12 that runs endlessly is disposed at a position close to the weight side conveyors 1 and 2 from the center of the guide plate 11. Also, boss 10
A suction vibe 1 has an opening at the top and communicates with a suction pipe 13 through which air is drawn by a suction blower.
4, and a lever 16 that swings about a support shaft 15 when a handle 19 is operated, and has a cover 17 on its upper part that opens and closes the opening of the suction vibrator I4. A spring 18 is attached to the lever 16, and the cover 17 normally closes the opening of the suction vibrator 14.

Further, an iron piece 20 is fixed to the lower end of the lever 16, and a proximity switch 21 for the power supply of the driving device of the saxilan blower is arranged on the boss 10 near the iron piece 20.

When the yarn end is wrapped around the upper end of the peg tray 3 to 4 times and placed in the hole to prepare the yarn supply package, the operator lowers the handle 19 and performs the threading operation.

When the handle 19 is lowered, the cover 17 on the top of the suction vibrator 14 opens, and the iron piece 20 of the lever 16 approaches the proximity switch 21 and is energized, causing the suction pipe 13 to close.
The suction blower connected to starts rotating.

Suction vibe 1 is created by the suction blower.
Air is sucked from 4 and the yarn end placed on the peg tray T is sucked into the core. And the suction thread length is
Determined by the operator's judgment.

When the thread end pulling operation is finished, the operator raises the handle 19 to stop the suction blower. The time the suction blower must be operated is 1/2 of the total time.
Since it is approximately 0, driving the suction blower only when necessary results in a very large energy saving.

After stopping the suction blower, move the yarn supply package E to position D.

However, between the transport conveyor 3 and the weight side rear conveyor 2, there is a swing arm 23 that is fixed to one end of a swing arm 23 that is swingably supported by a support shaft 22 and biased counterclockwise by a spring 25. A stopper 24 is interposed.

The operator manually lowers the stopper 24 and moves the yarn supply package E to the D position.

This manual extraction device may be provided with 2 sets per 1 spindle, or 1 set per 1 spindle, 1 set per 2 spindles.
A set may also be provided.

Note that 26 is a free roller for smooth movement of the tray T.

C.9 Effects of the invention Since this invention is configured as explained above,
This produces the effects described below.

That is, since it is not necessary to provide a very large automatic yarn end pulling device, installation space can be saved. Furthermore, it is possible to cope with frequent changes in lots and changes in the form of yarn supply packages.

Furthermore, the suction blower for taking out the yarn end is operated only when necessary, resulting in significant energy savings.
