Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vacuum table adjusting device that can open a fabric so that the stitch line of the fabric becomes close to a straight line.

[Prior Art] Conventionally, as this type of vacuum stand, the one shown in FIGS. 3 and 4 has been proposed. In FIG. 3 and FIG. 4, a shuttle 4 is connected to a suction blower 1 having an exhaust duct 2 through a connecting duct 3, a vacuum board 5 is mounted on an upper part of the shuttle 4, and a vacuum board 5 is attached to an upper surface of the vacuum board 5. The punching board 6 provided with a large number of holes 6'is fixed, and the upper surface of the punching board 6 and the vacuum board 5 are configured to be covered by a cover 7. The upper surface of the cover 7 has a small opening 8 '. The plates 8a and 8b are configured to slide.

In the conventional vacuum table thus constructed,
Opening plate 8 being sucked by the suction blower 1 as shown in the figure
Place the respective fabrics 9 and 10 on a and 8b, and fabrics 9 and 1
When the seam line 11 of 0 is placed at the facing end of the opening plates 8a and 8b, that is, the center line 12, and the respective opening plates 8a and 8b are moved in the opposite directions, the respective fabrics 9 and 10 are moved to the opening plate 8a. , 8b, and the seam line 11 of the fabrics 9, 10 can be aligned with the center line 12.

[Problems to be solved by the invention] However, since the cloths 9 and 10 are not actually the same area, when the opening plates 8a and 8b are opened at the same speed in the opposite directions,
When the fabric 10 having a large area is pulled, the seam line 11 is displaced from the center line 12 as shown in FIG.

In order to solve this problem, when the areas of the fabrics 9 and 10 are different, the dimensions of the opening plates 8a and 8b can be changed, or the opening plates 8a and 8a can be changed.
Adjust the moving order of 8b, change the opening speed of the opening plates 8a, 8b, and cover part of the punching board 6, and adjust the seam line 11 of the fabrics 9 and 10. It is made to coincide with the center line 12.

However, even in this configuration, since there are many combinations of different sizes of the fabrics 9 and 10, the above-mentioned adjustment must be performed every time this combination is changed, and there is a problem that the work becomes complicated. It was

According to the present invention, a partition plate that divides the vacuum board into a plurality of areas is provided in the kettle, suction can be adjusted by a damper for each of the plurality of areas partitioned by the partition board, and the seam line of the fabric can be aligned with the center line. It is an object of the present invention to provide an adjusting device for a vacuum table.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a vacuum board provided with a punching plate on the upper surface of a shuttle connected to a suction blower, and covers the vacuum board and the punching plate with a cover. In a vacuum stand in which an opening plate provided with a large number of small holes is slid on the upper surface of the cover to open the cloth on the opening plate, a partition plate for dividing the vacuum board into a plurality of areas is provided in the hook. And a damper is provided for each of the plurality of areas of the vacuum board, and the suction angle of the plurality of areas of the vacuum board is adjusted by adjusting the opening angle of the damper.

[Operation] According to the present invention, by combining the fabrics of different sizes, the dampers provided in the plurality of areas are manually or manually rotated by a cylinder or the like to a desired angle, whereby the fabrics of the plurality of areas are respectively rotated. Can be set to a predetermined value so that the seam line of the fabric can be aligned with the center line at the same opening speed of the opening plate.

[Embodiment] Referring to FIG. 1, in one embodiment of the present invention, 1 is a suction blower, 2 is an exhaust duct, 3 is a connecting duct, 4 is a hook, 5 is a vacuum board, 6 is a punching board, and 7
Is a cover, and the construction thereof is the same as that of the above-mentioned conventional example, so the description thereof will be omitted. Dampers 16, 17 at the bottom of areas 14, 15 respectively
Is rotatably provided. These dampers 16 and 17 may be manually rotated to have a predetermined angle according to a combination of fabrics having different sizes, or may be driven by a cylinder or a motor.

In this embodiment having such a configuration, the openings of the dampers 16 and 17 are set in advance according to the sizes of the fabrics 9 and 10, and the opening plates 8a and 8b of the vacuum board 5 are set as shown in FIG. Place the fabrics 9 and 10 on the top so that the seam line 11 substantially coincides with the center line 12. At this time, the suction force of the fabrics 9 and 10 is the opening plates 8a and 8b.
Since the above is almost the same, when the opening plates 8a and 8b are opened at the same speed, the stitch lines 11 of the fabrics 9 and 10 do not deviate from the center line 12, and the fabrics 9 and 10 are placed on the cover 7 of the vacuum board 5. It can be spread neatly.

In the above embodiment, the partition plate 13 is provided in the shuttle 4,
Although the inside of the vacuum board 5 is divided into two, in order to make the suction of the fabrics 9 and 10 on the vacuum board 5 even, a partition plate that divides into three or more is provided, and a damper is provided in each divided area. May be.

[Advantage of Invention] Since the present invention is configured as described above, different suction can be performed in the divided areas on the vacuum board.
Also, the suction can be modified by different sized combinations of fabrics, so that the fabric placed on the opening board on the vacuum board will be centered on the seam line of the fabric, regardless of the combination. There is an advantage that it can be opened evenly without shifting from the line.
