Description

[Detailed Description of the Invention] The present invention relates to a multi-head sewing device that uses a multi-head sewing machine to sew futons and other large sewing objects.

In conventional multi-head sewing machines, the horizontal mounting frame on which multiple sewing machines are attached is fixed, so when you insert or remove a frame on which a workpiece such as a futon is stretched, which is placed below the sewing machine, the sewing machine needle does not touch the frame. To do this, the individual sewing machines were moved up and down or rotated to raise the sewing machine needle high above the frame and pass it through the frame. Therefore, it is necessary to move a plurality of sewing machines up and down and rotate each time the frame is put in and taken out, which takes time and labor and obstructs the flow of sewing work. The present invention aims to provide a multi-head sewing device that solves these problems.

This invention relates to a multi-head sewing device in which a plurality of sewing machines are attached to a sewing machine mounting frame, and a frame on which the workpiece is stretched is movably mounted below the sewing machines, in which one end of the sewing machine mounting frame is pivotally supported and the other end is provided with a lifting device, which allows the sewing machine mounting frame to be tilted freely. An embodiment will be described below with reference to the drawings.

In the figure, 1 is the horizontal frame for attaching the sewing machine, 2, 2', etc. are the sewing machine machines, 3 is the power shaft, 4 is the motor, 5 is the flexible joint, 6 is the trolley, and 7 is the frame for stretching objects to be sewn such as futons. , 8 is a hydraulic cylinder that is a lifting device that lifts the other end of the sewing machine mounting horizontal frame 1;
Reference numeral 9 indicates a pivot shaft of the sewing machine mounting horizontal frame 1; 10 and 10' indicate support stands provided on the left and right sides of the sewing machine mounting horizontal frame 1;
1 and 11' are guide plates provided at the left end of the sewing machine mounting horizontal frame 1, and 12 is a guide plate that accurately moves the sewing machine mounting horizontal frame 1 up and down,
Centering recess for left and right positioning,
Reference numeral 13 denotes a fitting protrusion vertically provided at the lower left end of the sewing machine mounting horizontal frame 1 to be fitted into the fitting recess. In this embodiment, the futon is pasted on the frame 7 and the sewing machine 2,
2'... When the hydraulic cylinder 8 is operated when moving the frame 7 downward and when pulling out the frame 7 after sewing is completed, the sewing machine mounting horizontal frame 1 is rotated around the right end pivot 9 and is attached to the sewing machine mounting horizontal frame 1. The plurality of sewing machines 2, 2', . When sewing, the horizontal frame 1 for mounting the sewing machine is lowered to the horizontal position, and the sewing machines 2, 2', etc. are operated to perform sewing. Even if you lift the sewing machine mounting horizontal frame 1, the sewing machines 2, 2'
Since the operation shaft and power shaft of ... are connected by a flexible joint 5 at their base end sides, there is no problem in tilting the sewing machine mounting horizontal frame 1. Furthermore, since the right end of the horizontal sewing machine mounting frame 1 is pivoted, tilting of the horizontal sewing machine mounting frame 1 can be done more smoothly than raising and lowering the entire sewing machine mounting horizontal frame, and it is also possible to set the vertical and horizontal positions when it is returned to the horizontal position. can be done accurately. The sewing machines 2, 2', etc. will not be able to operate unless the needle of the sewing machine matches the hook of the lower shaft with a high degree of accuracy, so the setting of the horizontal operating position of the sewing machine mounting horizontal frame 1 must be performed with a high degree of precision. is required. In this respect, if one end is pivoted as in the present invention and the pivot point is constant, it can be returned to the set position accurately and easily.

As described above, according to the present invention, by pivoting one end of the sewing machine mounting horizontal frame and tilting the sewing machine mounting horizontal frame by raising and lowering the other end, multiple sewing machines can be simultaneously lifted and the workpieces to be sewn can be stretched. The suspended frame can be taken in and out easily and quickly. Furthermore, the sewing machine mounting horizontal frame can be accurately and easily set up and down, left and right, and front and back to a horizontal position where the sewing machine can be operated.
