Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a doffing device for doffing a fully wound bobbin formed on a bobbin holder of a winder or the like.

Many types of doffing devices have been proposed that automatically doff a fully wound bobbin from the bobbin holder of the winder in sequence by moving the doffing cart, but most of these doffing devices send a signal from the dotting cart to the winder. Thereafter, the winder automatically stops the rotation of the bobbin holder, unwinds the bobbin, and moves on to the next full bobbin transfer operation.

Although such an automatic dotting device is very convenient, it has the disadvantage that the equipment cost is extremely high, and it requires major modification of existing winding machines, so it is not applicable except for newly installed winding machines. The current situation is that it is difficult to

In view of the current situation, it is an object of the present invention to provide a dotting device that can be easily and inexpensively implemented on an existing winding machine, and is a spindle winding machine in which a plurality of winding machines are arranged side by side in the spindle row direction. A dotting carriage movable in the spindle row direction is disposed along the front surface, and an engagement tool for holding an operating lever of a winding machine that rotates and stops a bobbin holder, unwinds the bobbin, etc. on the dotting carriage. and a moving member for moving the engaging tool in a direction parallel to the spindle row direction, in a direction perpendicular to the parallel direction to advance and retreat from the spinning take-up device, and in an up and down direction. It is in.

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention.

In the figure, reference numeral 1 denotes a two-piece winding machine that simultaneously forms two packages on one bobbin holder 2, and is equipped with a friction roller 3, a traverse box 4, etc. A plurality of units are arranged side by side to form a spinning take-up device.

The bobbin holder 2 of the winding machine 1 is cantilevered in the horizontal direction at right angles to a machine stand 1' disposed along the direction of the spindle row.

When the control lever is moved laterally, the bobbin holder 2 moves away from the friction roller 3. When the bobbin holder 2 moves further, a brake is applied to the bobbin holder 2 to stop it, and when the bobbin holder 2 is moved above the brake activation position, the bobbin support is loosened. It is.

6 is a bobbin 8 inserted into the machine base 1' and the bobbin holder 2.
The auxiliary guide 6 is a plate-shaped auxiliary guide that is located between the machine base 1' and moves back and forth with respect to the machine base 1'.
It is attached to the tips of two rods 7 which are slidably supported in the bobbin holder 2 and can be moved back and forth in the axial direction of the bobbin holder 2.

As described above, this auxiliary guide 6 is located between the machine base 1' and the bobbin 8, and as described later, when the fully wound bobbin is taken out, it moves back and forth and engages with the end surface of the bobbin 8 on the machine base 1' side. After being pushed out from the bobbin holder 2, it returns to its original position.

Reference numeral 10 denotes a doffing truck that runs on a rail along the front surface of the winder 1, and the truck 10 is provided with an operating device 11 for the operating lever 5 according to the present invention.

The operating device 11 moves the winder frame 1' by means of a fluid cylinder 14 on two rails 12 and 13 fixed on the frame.
A slide plate 1 provided to reciprocate in a direction perpendicular to the
5. Two rice cookers fixed to the slide plate 15 '16.
17 and reciprocated in parallel with the machine base 1' by means of a fluid cylinder 18; a lever 21 supported vertically rotatably on a support frame 20 protruding from the moving plate 19; At the tip of the lever 21, an engaging tool 22' consisting of two bands 22 that are opened and closed by an electromagnet or a compressed air cylinder, etc. is provided, and at the rear end, the lever 2 is attached.
1 is connected to a fluid cylinder 23 that rotates it in the vertical direction.

Further, the dotting cart 10 is provided with a moving device 30 for reciprocating the auxiliary guide.

This moving device 30 consists of a fluid cylinder 31.32 attached to a frame (not shown), a puller 33 and a pusher 3 attached to the cylinder 31.32 so as to be movable back and forth.
4, and a fluid cylinder 31 is rotatably attached to rotate the puller 33 in the vertical direction.

35 is a fluid cylinder provided for this purpose.

40 is a peg that receives the fully wound bobbin 8 and transfers it to a peg of a bobbin cart that descends and waits.

In order to stop the bobbin holder 2 of the winder 1 and take out the fully wound bobbin 8 using the device consisting of the above, first, the dotting cart 10 moves to a predetermined position and stops, and then a thread guide and a cutter (not shown) are moved to a predetermined position and stopped. , the preventive yarn is taken up by an aspirator or the like.

Next, the fluid cylinder 14 is activated, the slide plate 15 moves forward on the rail 12.13 toward the machine base 1', and when the band 22 of the lever 21 reaches just above the operating lever 5 of the winding machine 1, a limit (not shown) is reached. The slide plate 15 stops when it comes into contact with the switch.

Next, the fluid cylinder 23 acts to rotate the lever 21 downward.

Due to this rotation, the band 22 comes into contact with the operating lever 5 and grips the operating lever 5 by the operation of an electromagnet or the like (the band 22 may be in a closed state without necessarily having to grip it).

After this, the fluid cylinder 18 operates and the movable plate 19 moves the machine 1
When the bobbin holder 2 moves to the left along the line 22, the operating lever 5 held by the band 22 moves along the L-shaped guide groove 5', and the bobbin holder 2 moves away from the friction roller 3.

When the bobbin holder 2 is further moved to the left, the brake device is activated and the bobbin holder 2 completely stops rotating.

Next, the fluid cylinder 23 moves freely and moves the operating lever 5 together with the band 22 upward along the guide groove 5'.

By this operation, the bobbin holder 2 loosens its grip on the fully wound bobbin 8.

When it is confirmed that this operation is completed, a signal is issued, the fluid cylinder 31 is activated, and the puller 33 is projected to the rear of the auxiliary guide 6.

Next, due to the operation of the fluid cylinder 35, the fluid cylinder 3
When the puller 1 rotates, the puller 33 attached thereto also rotates and moves to a position where it mutually overlaps the auxiliary guide 6.

Thereafter, the puller 33 retreats and the auxiliary guide 6 is pulled out, so that the fully wound bobbin 8 is pushed out and held by the peg 40 waiting in front of it.

Next, the peg 40 descends and tilts downward to transfer the fully wound bobbin 8 to the upwardly protruding peg of the bobbin cart, and the pusher 34 protrudes to return the auxiliary guide 6 to its original position.

After that, when an empty bobbin is inserted into the bobbin holder 2 by the empty bobbin insertion means, the band 22 is rotated downward by the operation of the fluid cylinder 23, and the operating lever 5 is lowered to remove the empty bobbin inserted into the bobbin holder 2. Tightly attach.

Next, as the movable plate 19 moves to the right by the action of the fluid cylinder 18, the operating lever 5 together with the band 22 moves into the guide groove 5'.
After the brake is released, the empty bobbin comes into contact with the friction roller 3 and stops at a position where it starts rotating.

After this, the fluid cylinders 23, 14 are activated in sequence, the band 22 moves upward, and the slide plate 15 returns to its original position.

Next, when the spun yarn is threaded onto the bobbin and the yarn begins to be wound up, the dotting cart moves toward the next winding unit to be dotted, and the same operation as described above is repeated.

As described above, the present invention provides a dotting cart with a movable member that reciprocates in a direction parallel to and at right angles to the winding machine base, and a band that moves up and down on the member. Since the operating lever of the winding machine that protrudes from the side can be operated from the dotting cart side, there is almost no need for additional equipment on the winding machine side, and there is no special design to match the dotting cart, and the equipment cost is high. Much cheaper.

In particular, there is a great advantage in that conventional equipment or existing equipment (winding machine) requires almost no modification, and only the dotting cart side needs to be manufactured.

It should be noted that the engaging tool according to the present invention can be of any shape, in addition to the one that can be opened and closed as shown in the embodiments, and that can be engaged with or fitted with the operating lever of the winding machine.
