Description

[Detailed description of the invention] Technical field The present invention relates to a carpenter tufting machine.

Prior Art FIG. 1 shows a conventional carpet tufting machine.

In this tufting machine, the rotation speed of the feed roller 1 that sends out the yarn 4 for the pile 5 is always constant.
The guide bar 2 was provided immovably. In contrast to the guide bar 2, a needle bar 3 is provided so as to be movable in the width direction (left and right) of the carpet, and various patterns are woven into the base fabric 6 of the carpet during tufting. This made it possible to prevent linear weaving from occurring on the base fabric 6.

However, with this tufting machine, the needle par 3
When the thread moves in either the left or right direction, the thread is pulled between the feed roller 1 and the guide bar 2 and between the guide bar 2 and the needle parr 3, and a large tension is temporarily applied to the thread 4. . After the needle 9 tufts the thread 4 into the carpent base fabric 6, the tension of the thread increases and the height of the pile decreases, and when the guide bar 2 returns from the moved position to the original position, K is Since the yarn 4 is in a relaxed state with no tension applied at all, the height of the pile 5 becomes high after tufting.The height of the pile 5 on the surface of the garment becomes uneven, and the carpent surface becomes rough. There was a flaw in the condition.

Purpose The purpose of the present invention is to provide a carpent tufting machine that eliminates the above-mentioned defects and is capable of forming piles so that the surface of the carpent base fabric is smooth without creating unevenness on the surface. .

Embodiment An embodiment embodying the present invention will be described below with reference to FIGS. 2-3.

The feed roller 1 sends out a plurality of yarns 4 for the piles 5 released from the cone through the guide bar 2VC while actively rotating, and guides them to the guide bar 1j: yarn 4 = -dolper 3. The guide bar 2 and the needle par 3 are both movable laterally, and the needle par 3 is connected to an interlocking device 7 for interlocking the guide bar 2 with the needle par 3.

The interlocking device 1 is connected to a rotational speed adjusting device 8 that adjusts the rotational speed of the feed roller rough so that a constant tension is always applied to the yarn 4.

The needle parr 3 has a plurality of needles 9 installed at equal intervals on its lower surface, and the needles 9 tuft the yarn 4 onto the base fabric 6 to form the pile 5. It is something.

The operation of the tufting machine configured as described above will be explained below.

The interlocking device T has a function of interlocking the guide bar 2 and the needle par 3 in the same direction and electrically sensing the movement of both 2 and 3. And the interlocking device T is
As both bars 2 and 3 move, an electrical signal is sent to a rotational speed adjustment device 8, and the rotational speed adjustment device 8 determines the rotational speed of the feed roller 1 in accordance with the electrical signal. That is, the rotational speed of the feed roller 10 increases with the movement of both bars 2.3, and the amount of yarn stylus also increases. The rotational speed decreases when both bars 2.degree. 3 return from the moved position to the original position, and the amount of yarn fed out also decreases.

As shown in FIG. 3, when the guide bar 2 and needle par 3 move in either the left or right direction during tufting, the guide bar 2 pulls the thread 4 in the moving direction. At this time, the movement of the guide bar 2 is sensed by the interlocking device 7,
Since the rotational speed of the feed roller rough is increased by the signal from the interlocking device 7 via the rotational speed adjusting device 8, the length of the yarn 4 fed by the feed roller 1 to the guide bar 2 is also increased. Therefore, no large tension is applied to the yarn 4 between the feed roller 1 and the guide bar 2. In addition, as mentioned above, the guide bar 2 and needle par 3 are
Since they work in synchronization in the same direction, no unnecessarily large tension is applied to the thread 4 between the two 2 and 73.

Furthermore, when the guide bar 2 and the needle par 3 return from the moving position to their original positions, the amount of yarn 4 fed out decreases as described above. It is not too long to loosen, and the thread 4 is under appropriate tension. Since both bars 2 and 3 are interlocked, the tension applied to the thread 4 does not change between them.

In this way, the yarn 4 is tufted onto the base fabric 6 of the carpet by the needle 9 under constant and appropriate tension, so that the height of the pile 5 varies after tufting, resulting in The heights will not be uneven.

Effects As described in detail above, the present invention includes a feed roller 1 which is rotatably provided for sending out yarn for the pile 5, and a horizontal movement mechanism by which the yarn 4 is fed from the feed roller 1 via a guide bar 2. Possible needle par 3 and same needle par 3
and a plurality of needles 9 for tufting the thread 4 onto the base fabric 6 of the carpent to form the pile 5.
The tufting machine has an interlocking device 7 that moves the guide bar 2 in synchronization with the movement of the needle par 3 in the same direction, and is connected to the interlocking device 7 and moves the feed roller 1 according to the interlocking device 7. The rotational speed adjusting device 8 and - for controlling the rotation provides an excellent effect in that the pile can be formed so as to have a smooth surface on the base fabric of the carpet.
