Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a base fabric tensioning device for an automatic seven drag loom or the like.

Conventional technology Generally speaking, in manufacturing hook woven carpets,
It is necessary to stretch the base fabric that forms the basis of the frame onto the frame, and the four sides of the base fabric are hooked to a number of pins planted at intervals in the frame. It's line processing.

By the way, conventionally, when tensioning the base fabric onto the frame, the base fabric was simply pulled manually and then sequentially secured to pins on the sides of the frame.

Problems to be Solved by the Invention However, there are two to three problems in line processing using a hook machine.
Since a considerable amount of pressing force is applied to the base fabric, it is desirable to stretch the base fabric strongly against this pressing force so as to prevent the phenomenon of dropping as much as possible. There were limitations and there was a risk of problems in wire processing.

Means for Solving the Problems Therefore, the present invention aims to provide a device that can easily and reliably tension the base fabric, and in which the rail material 7 installed on two opposing sides and the rail material 7 Locking material 8.8
' to form a tension frame 5, the locking material 8.8' has a large number of pins 11 planted at intervals, and the rail material 7 has a large number of pins 10 planted throughout its entire area. The runner 9 is fitted in such a way that it can be slid slightly, and at least one of the locking members 8' is configured to be able to move forward and backward along the rail member 7.

Therefore, when tensioning the base fabric 6, the movable locking member 8' is pushed inward of the tensioning frame 5 along the rail member 7, and the runner 9 is also locked at the same time. The runners 9 are slid in the same direction as the runners 8', so that no gaps are created between the runners 9. Then, in this state, the three side edges of the base fabric 6 are inserted into the locking material 8 and the pins 10.11 of the rail material 7 to lock them, and the line to be cut is inserted into the locking material 8' which can move forward and backward to lock them. . Then, the locking material 8' is stretched along the rail material 7 on the tension frame 5.
The base fabric 6 is pulled outward. At this time, the runner 9, which is slidably fitted into the rail material 7, also slides slightly in accordance with the elongation of the base fabric 6 as it is pulled, so that the entire area of the base fabric 6 is stretched uniformly. Kneading is carried out in this state, and upon completion, the locking material 8' is pushed inward of the tensioning frame 5 to loosen the tension in the base fabric 6.

Example Hereinafter, one example of the present invention will be explained with reference to the drawings.
is a main frame assembled in a rectangular shape, and a support frame 2 is attached to one side of the main frame in the longitudinal direction (X-ray direction). Jin's support frame 2
In this case, the end frame 2' is an independent frame, and the motor 3 provided in the main frame 1 is
The main frame 1 can be moved back and forth at a fixed distance in the X-ray direction by a threaded rod 4 rotated by the main frame 1. Reference numeral 5 designates a tensioning frame on which a base fabric 6 is stretched, in which two opposing sides along the X-ray direction of the main frame 1 are made of a channel-shaped rail material 7 with a lip in cross section with a groove arranged above, and the other opposing sides are Two sides are provided with locking members 8 and 8', which are attached to the support frame 2, and one of the locking members 8' is attached to the end frame 21 so that it can move forward and backward. 9Fi
The runner is a runner in which pins 10 are implanted one tree apart, and a large number of pins 10 are fitted in the entire area of the rail material 7 so as to be able to slide slightly. Numerous pins 11 are installed at intervals on the locking member 8.8'.
A guide F rail 2 guides both ends of the locking member 8'' and is attached to the inner surface of the rail member 7.As the 13Fi locking member 8' is pushed inward, the runner 9 is moved in the same direction. A sliding arm is attached to both ends of the locking member 82,
It extends over the upper surface of the rail material 7. 14 is the X in main frame 1
The frame is passed and stretched in the Y-line direction perpendicular to the line direction, and is movable in the X-ray direction 1 above the nine base cloth 6, with nine frames. A movable workbench 1
5 is installed.

Reference numeral 16 denotes a hook machine installed on the workbench 15 so as to be able to freely turn and move up and down.

In the embodiment shown in the drawings, the locking member 8' is moved forward and backward by the rotational force of the motor 3, but various methods are possible, such as using manual rotational force or hydraulic pressure.

Further, both of the locking members 8, 8' may be configured to advance and retreat in opposite directions.

Effects of the Invention As described above, the present invention comprises a tensioning frame 5 on which a base fabric 6 is stretched, a rail material 7 on two opposing sides, and a large number of runners 9 with pins 10 implanted over the entire area thereof. are fitted in a slightly slidable manner, and the two sides sandwiched by the rail material 7 are used as locking members 8.8' with a large number of pins 11 planted at intervals, and at least one of the locking members 8 Since the base fabric 6' is configured to move forward and backward along the rail material 7, the base fabric 6 can be stretched while pushing the locking member 8' inward of the tensioning frame 5.
The edge can be inserted into the pin 10.11 with a moderate degree of tension, and this operation can be easily carried out without requiring great force. Then, the base fabric 6 is a locking material 8
By retracting ' to the outside of the tensioning frame 5, the entire area is pulled, and the optimum tensioning condition for kneading can be easily obtained.

Furthermore, if arms 13 for pushing the runner 9 are provided at both ends of the locking member 8', the work of pushing the runner 9 when attaching and detaching the base fabric 6 to and from the tensioning frame 5 can be done by moving the locking member 8' forward. At the same time, this can be done automatically, improving overall work efficiency.
