Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a supporting device for a base fabric in an automatic hook-drag machine.

Conventional technology In the past, hook-weaving carpets were woven using a hand-held hook machine following patterns drawn on the base fabric, but this required considerable skill and
Due to the heavy labor, the production efficiency was inefficient.

For this reason, an automatic weaving method has been developed in which a hook machine is movably arranged above a horizontally stretched base cloth to weave a pattern input in advance onto the base cloth.

Problems to be Solved by the Invention However, automatic weaving type hook machines cannot adjust the pressing force against the base fabric unlike hand-held type hook machines, so the base fabric tends to sink, especially when the base fabric is stretched. The sinking angle of the base fabric becomes large near the frame, and as a result, the design pattern, which is set on the basis of the horizontal state, is woven into the base fabric in a shifted state, resulting in an inconvenience that the finished weaving becomes rough.

Therefore, a net was stretched below the horizontally stretched base fabric, and the tension prevented the base fabric from sinking, making it possible to more accurately weave the design.However, due to the vertical movement of the needle of the hook machine, This causes the inconvenience of the net being cut, which necessitates frequent replacement of the net in order to maintain the tension of the net, and the yarn woven by the hook machine may become pinched at the intersection of the nets, resulting in a loss of completion. When removing the item, the threads sometimes fell out.

Means for Solving the Problems The present invention eliminates the inconveniences and drawbacks of the conventional art, and makes it possible to weave the intended pattern without any hindrance. The underframe 8 is movable in the linear direction, and the underframe 8 is
In an automatic hook drag loom equipped with a workbench 9 movably attached to the Y-line direction perpendicular to the X-rays and a hook machine 10 attached to the workbench 9 so as to be pivotable about a needle 11, two rotatable A support frame 12 consisting of rollers 14 arranged parallel to the Y-line direction is placed below the base fabric 5, and the needle 11 of the hook machine 10 is positioned between the two rollers 14, It is arranged so that it can be moved freely according to the movement.

Function: Therefore, the support frame 12 moves in synchronization with the movement of the underframe 8 in the X-ray direction, and the needle 11 of the hook machine 10 always works while being located between the two rollers 14. During the weaving process, the support frame 12 supports the base fabric 5 to keep it at a constant depression in the X-ray direction,
This corresponds to the hook machine 10 moving in the Y-line direction.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a rectangular main frame, which is installed on the floor by legs 2 at the four corners. 3 is a support frame detachably attached to the main frame 1 in the space 4 at one end of the main frame 1 in the longitudinal direction (X-ray direction);
A wooden frame 7 with a large number of nails 6 installed thereon is removably placed thereon. 8 spans in the short direction (Y-line direction) perpendicular to the longitudinal direction of the main frame 1, and is movable above the stretched base fabric 5 along the longitudinal direction (X-ray direction) of the main frame 1. With the attached frame,
A workbench 9 is attached to the underframe 8 and is movable in the short direction (Y-line direction) of the main frame 1.
Reference numeral 10 denotes a hook machine, which is attached to the workbench 9 so as to be able to rotate around the needle 11 and to be able to move up and down. Reference numeral 12 denotes a support frame which is movably attached below the stretched base fabric 5 along the longitudinal direction (X-ray direction) of the main frame 1, and includes two support frames with a large number of flanges 13 provided at intervals. rollers 14 are arranged in parallel, and both ends of the rollers 14 are rotatably attached to a connecting body 15. Reference numeral 16 denotes a wheel attached to the outer side of the connecting body 15, and is engaged with a rail 17 formed inside the main frame 1, and this rail 17 bends slightly downward 18 when passing under the support frame 3. and reaches the space 4. 19 is an arm that connects the underframe 8 and the support frame 12, and it connects the needle 11 of the hook machine 10 to 2.
The support frame 12 is located in the middle of the book roller 14 and connected, and the support frame 12 also moves in synchronization with the movement of the underframe 8 in the longitudinal direction (X-ray direction). A connecting rod 20 hangs down from the connecting body 15 and is connected to the arm 19 so as to be movable up and down. 21 is a pole screw that moves the underframe 8 and the support frame 12 in the longitudinal direction (X-ray direction);
The power of the servo motor 22 is transferred to the gear box 23,
It is transmitted via the connecting shaft 24. A ball screw 25 moves the workbench 9 in the short direction (Y-line direction) with respect to the underframe 8, and is driven by a servo motor 26. Reference numeral 27 denotes a rotary disk for rotating the hook machine 10 around the needle 11, which is driven by a servo motor 28. Reference numeral 29 denotes a column that supports the hook machine 10 so that it can be raised and lowered, and is equipped with a cylinder 30 for raising and lowering.

Effects of the Invention As described above, the present invention provides a support frame 12 that moves in the X-ray direction in synchronization with the underframe 8 that is provided to be movable in the X-ray direction of the main frame 1, and a base fabric 5 that is stretched. Since it is provided below, it minimizes the sinking of the base fabric 5 during the weaving process, and evens out the sinking over the entire surface of the base fabric 5, making it possible to accurately weave the planned design and create a beautiful appearance. Therefore, maintenance and inspection of the support frame 12 is extremely easy.

In addition, two rollers 1 constituting the support frame 12
When a large number of flanges 13 are provided at intervals on the base fabric 5, the contact area of the base fabric 5 becomes small, and the friction during movement of the support frame 12 is reduced. It does not cause any damage.
