and a bobbin stripper 400 for stripping off the remaining yarn from the empty bobbin B pulled out by the bobbin mover 200.

The circulation conveyance path L1 extends endlessly in front of the bobbin mover 200, between the bobbin mover 200 and the package loader 300, and in front of the package lifter 100, and several trays T circulate there. These trays T are stopped at predetermined positions for each predetermined operation.

The package P rolled up by the wine goo is steam-treated and set by a steam setter (not shown). From there, the package P is inserted into the tray T and sent to the conveyance path of the stocker conveyor 4, where it is on standby. Then, the package P is sent out to the conveyance path L2 every time it is necessary, and
When the thread reaches position , the end of the thread is taken out. This alignment device 1 uses one that has been commonly used in the past.

If the picking fails, the package P is sent to the return conveyance path and sent to the picking device 1 again.

Next, the package and empty bobbin delivery device of the present invention will be described with reference to FIGS. 2 to 4.

In this device, a package lifter 100 and an overhead conveyor 2 work together to pick up the two-tiered empty bobbin insertion spindle S from the overhead conveyor 2 and pass the two-tiered package insertion spindle S to the overhead conveyor 2. It is something.

The package lifter 100 is provided beside the annular transport path Ll, and the spindle S is placed on the tray T in the annular transport path L1.
The receiver has a transfer position, a standby position above the transfer position, and a hanger 101 that can be stopped at a position approximately 5 mm from the standby position.

As shown in FIG. 3, an empty bobbin hook 101a and a package hook 101b are formed on both sides of the hanger 101, respectively. Note that the hanger 101 is controlled to stop by a sensor inside the package lifter 100.

A bracket 10 is attached to the upper end of the package lifter 100.

When the hanger 3 moves to the 0 position, the roller 103 contacts the support plate 2a to prevent the hanger 3 from wobbling.

As shown in FIG. 4, the hanger 3 is cut into two parts, and the cut 3a extends to the rear wall. Further, raised portions 3b are formed at the front and back along the notch 3a to prevent the upper flange of the spindle S received in the notch 3a from shifting. 2
As shown in FIG. 3, the hanger 3 of the overhead conveyor 2 holding the stacked empty bobbin insertion spindles S is as shown in FIG.
Package lifter 00 moves from the empty bobbin hanger 101a side of the hanger 101 in the direction of the arrow.

We will explain how to transfer the package and empty bobbin from this state.

The hanger 101 holds the package insertion spindle S on the package hook 101b and is raised to a standby position by 1" and is waiting.

The hanger 3 of the overhead conveyor 2 has a hook 10
When it reaches position 1a, it stops, and the held two-stage empty bobbin insertion spindle S is pushed into the hook 101a. At the same time, the hanger 101 rises by about 5 mm and holds the lower flange of the two-tier empty bobbin insertion spindle S.
Geru. In this state, the hanger 3 advances to the position of the hook 10]1) of the hanger 101, and stops with the package insertion spindle S held there sandwiched therein.

Due to this series of movements, the two-tiered empty bin insertion spindle S prevents the lower end of the upper tier collar from colliding with the protruding portion 3b, and the head portion of the two-tier empty bin insertion spindle S does not collide with the raised portion 3b.
a and is transferred to the hook 101a.

At the same time as the hanger 3 advances to the position of the hook 101b,
The hanger 101 is lowered by about 5 mm. As a result, the upper flange portion of the package insertion spindle S is lowered between the raised portions 3b. When the package insertion spindle S is thus removed, the hanger 3 moves forward, while the hanger 10
1 descends and lowers the two-stage empty bin insertion spindle S, which was picked up earlier, onto the tray T waiting in the circulating conveyance path Ll.

Next, referring to FIG. 5, a transfer device including a bobbin mover 200 and a package loader 300 will be described.

The bobbin mover 200 is equipped with a chuck 203 at the tip and can be moved up and down by 1" along a vertical axis 201. The bobbin mover 200 is centered on the empty bobbin extraction position A, and has a transfer position C on the left and a stripper on the right. It has a chuck support arm 202 that can rotate toward the 400 side.

The chuck 203 normally has an opening larger than the diameter of the spindle S, and is designed to clamp the spindle S by supplying air. In addition, the chuck support arm 202 is normally placed on standby above the empty hobbin extraction position I. The package loader 300 is equipped with a package loading section 303 at the tip and can ascend and descend along the vertical axis 301. It also has a package support arm 302 that can rotate from the package receiving position to the transfer position.

A notch 304 is formed in the package placement section 303 to prevent the pegs of the tray T from colliding with each other when the package P is scooped up at the package receiving position opening. Also, a guard wall 30 is provided around the package placement section 303 to prevent the scooped out package P from falling.
5 is set.

The package support arm 302 is normally lowered and waiting at the package receiving position opening. When the package insertion tray T comes there by moving along the conveyance path extending from the pick-up device 1, the package P is placed on the package placement section 303.
Climb up on top of.

Also, bobbin mover 200 and package rotor 30
At the transfer position C between 0 and 0, a tray rotation device 5 and a yarn end suction device (not shown) are provided in the circulation conveyance path I71, and a yarn end suction device 6 for sucking and gripping the yarn ends upward is provided. .

On the other hand, as shown in FIG. 2, a release tension adjustment guide G is held between the two stacked packages P inserted into the spindle S. This also applies when inserting the empty bobbin B.

When the two-stage stacked empty bobbin insertion spindle S advances through the circulation conveyance path and reaches the bobbin extraction position A and stops, the chuck support arm 202 is slightly lowered and the chuck 20
3 holds the empty bobbin B in the upper stage. In this state, the chuck support arm 202 rises and rotates toward the stripper, whereupon the chuck 203 releases the empty bobbin B and returns to its old position.

On the other hand, at the transfer position C, a tray T, in which a spindle S from which an empty bobbin B has been removed by the bobbin mover 200, is already inserted is waiting.

The package loader 300 inserts the package P into the spindle S waiting at the transfer position C while the hobbin mover 200 is extracting the two-stage empty bobbin B. First, the package support arm 302 rises from the standby position opening while holding the package P, and then rotates to the transfer position C. At this time, the yarn end suction device 6 acts to suction and grip the exposed yarn end of the package P. The package support arm 302 descends slightly to untie the yarn end from the package P, and rises again to collect the unraveled yarn end into the yarn end suction device 6.
Suction it into the thread, secure the specified length of the thread end, and hold it. Next, the package support arm 302 descends to insert the package P into the spindle S, and rises again to return to the standby position.

The tray T from which the package P has been removed is sent out from the conveyance path I-i to the tray ejection conveyance path 1-6.

At the top of the spindle S at the empty bobbin removal position A from which the upper empty bobbin B has been removed, there is a release tension adjustment guide G.
There is. The package support arm 202 is lowered and the chuck 2
03 holds the tension adjustment guide l'G. Thereafter, the package support arm 202 rises, rotates to the transfer position C, and descends, and the loosening tension adjustment guide G is inserted into the spindle S at the transfer position C into which one package is inserted. The package support arm 202 then rises and returns to the standby position A.

Next, the package support arm 302 rises from the standby position opening while holding the next package P, and rotates to the transfer position C. At this time, the yarn end suction device 6 operates to suction and grip the exposed yarn end of the package P. The package support arm 302 descends slightly to untie the yarn end from the package P, rises again, and sucks the unraveled yarn end into the yarn end suction device 6 to ensure a predetermined yarn end length and hold it. .

Next, the package support arm 302 descends, inserts the package P into the spindle S, and returns to the standby position.

At the same time, the tray rotation device 5 rotates, working in cooperation with a movable yarn guide (not shown) to transfer the two yarn ends sucked into the yarn end suction device 6 to one end of the spindle S. The yarn is wound in the same direction as the winding direction, and the remaining yarn end is sucked into the spindle S by a yarn end suction device (not shown) located below the transfer position C.

In this way, the spindle S located at the bobbin extraction position A becomes empty, and the stoppage by the stopper is released, and the circulation conveyance path L
1 to transfer position C and stop. Further, the spindle S at the transfer position has the packages P piled up in two tiers, is released from being stopped by the stopper, advances through the circulation conveyance path L to the position of the package lifter 100, and stops there.

Next, the bobbin stripper 400 will be explained with reference to FIGS. 5 to 7.

The package support arm 202 of the bobbin mover 200 extracts the empty bobbin B from the spindle S which is in the empty bobbin extraction position A, and the chuck 401 of the bobbin stripper 400 opens to the position where it rotates 90 degrees in the direction of the arrow shown by the dotted line in FIG. The machine is waiting in the waiting state.

Although the upper and lower positions of the chucks 401 remain unchanged, the chucks 401 are moved toward and away from each other by an air cylinder 402, and at the same time they receive the empty bobbin B, they approach and grip the empty bobbin B.

Above the chuck 401, there is a thread suction pipe 403 that communicates with the duct and is slidably supported within the pipe and is biased upward by a spring (not shown). A moving pusher 404 is provided.

Further, below the chuck 401, an empty bobbin storage container 4 is provided.
06 is the setting.

Chuck 401 is chuck 2 of package support arm 202
When the empty bobbin B is picked up and held using the holder 03, the air cylinder 405 is activated, the pusher 404 is lowered, and the empty bobbin B is pushed down. As the empty bobbin B descends, the chuck 401 gradually approaches the conical outer diameter of the empty bobbin B. If there is any remaining yarn in the empty hobbin B, the yarn is squeezed by the edge of the chuck 401 and stripped off from the empty hobbin B. When the pusher 404 has completely lowered the empty hobbin B in this manner, the pusher 404 is slightly raised, and the stripped remaining yarn is sucked into the yarn suction pipe 403 and discharged. Further, the empty bobbin B falls into the empty bobbin storage container 406.

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

That is, it has become possible to automate the receiving and receiving of the empty bobbin insertion spindle from the overhead conveyor and the delivery of the package insertion spindle to the overhead conveyor without requiring any human labor.

Therefore, it has become possible to completely automate the operation of replacing the empty bobbin and the package and supplying the yarn to the two-stage yarn feeding type double twister.
