Description

[Detailed description of the invention] and industrial application fields. The present invention relates to eight consecutive edge folds of work cloth.

[Prior Art] Conventionally, this type of device has a template that determines the folding position of the work cloth, and folding blades that are arranged opposite each side of the template and extend along each side. However, the folding blades were configured to fold the edges of the work cloth by moving forward or backward, respectively.

[Problems to be Solved by the Invention] In actual sewing work, it is necessary to fold work cloth of various shapes, and each time the shape of work cloth changes, the worker creates a pattern based on the shape. The plate and the folding blade must be manufactured, which is uneconomical and requires a long manufacturing time.

[Object of the Invention] The present invention was made in order to eliminate the conventional drawbacks, and its purpose is to provide a work cloth that can fold the edges of the work cloth regardless of changes in the shape of the work cloth. An object of the present invention is to provide a continuous edge folding device.

[Means for Solving the Problems] The present invention includes a guide member in which a regulating portion for folding the edge of a work cloth is formed on one side, and a guide member that is reciprocated with respect to the guide member by a driving means, It is comprised of an actuating member for folding the edge of the work cloth with reference to the regulating part, and a feeding means for transporting the work cloth folded by the guide member and the actuating member along the fold line thereof. .

[Operation 1] In the present invention, the feeding means transports the folded work cloth along the fold line by cooperation of the guide member and the operating member.

[Example] The details of an embodiment of the present invention will be described below with reference to the drawings.

In the figure, a machine frame 1 is paired with a work table 3 on which a work surface 2 is formed and spaced apart from the work surface 2.

It is composed of an overhanging portion 4 facing toward the front.

A first base 10 is installed on this overhang 4, and a drive shaft 11 extending in the cloth feeding direction F is rotatably supported on this base 10, parallel to the drive shaft 11. A support shaft 12 is fixed to. A pulse motor 13 is fixed to the base 10, and this pulse motor 13 is connected to the drive shaft 11. Further, a movable table 14 is installed on the drive shaft 11 and the support shaft 12, and the movable table 14 is configured to reciprocate along the drive shaft 11 as the drive shaft 11 rotates.

A solenoid 15 is fixed to this moving table 14,
This solenoid 15 has a guide member 1 attached to a prismatic operating shaft 16.
7 is fixed. The solenoid 15 is configured to urge the guide member 17 in a direction perpendicular to the work surface 2 and in a direction toward or away from the work surface 2, respectively. The guide member 17 has a protruding guide plate 18 extending perpendicular to the cloth feeding direction F and parallel to the working surface 2 at its lower end, and a regulating portion 1 extending parallel to the cloth feeding direction F at its tip. is formed. The guide member drive unit is configured as described above.

On the other hand, a second base 20 is installed on the work table 3, and a drive shaft 21 extending perpendicular to the cloth feeding direction F is rotatably supported on this base 2o. A support shaft 22 is fixed parallel to the shaft 21. A pulse motor 23 is fixed to the base 20, and this pulse motor 23 is connected to the drive shaft 21. Further, a movable table 24 is installed on the drive shaft 21 and the support shaft 22, and the movable table 24 is configured to reciprocate along the drive shaft 21 as the drive shaft 21 rotates.

An operating member 25 is installed on the movable table 24 so as to be movable up and down in a direction perpendicular to the work surface 2, and a rack gear 26 is fixed to the operating member 25. Further, a pulse motor 27 is fixed to the movable table 24, and a pinion gear 28 that meshes with the rack gear 26 is fixed to the pulse motor 27.

The operating member 25 has an operating plate 29 formed at its upper end, and these two operating plates are parallel to the working surface 2 and are formed to protrude toward the guide plate 18 of the guide member 17. There is. Further, a hole 5 is formed in the work table 3, and the actuating plate 29 is moved from the position where it enters the hole 5 to the left side as seen in FIG. It is reciprocated between a position where it contacts the work surface 2 of the table 3. The operating member drive unit is configured as described above.

Further, a third base 30 is installed on the overhang 4, and a movable base 30 is mounted on this base 30 by a pulse motor 32.
1 is installed along the cloth feeding direction F so that it can reciprocate. A solenoid 33 is fixed to the moving table 31, and a feed leg 35 of the solenoid 33 is fixed to an operating shaft 34.

The feed leg 35 is arranged on a straight line passing through one regulating portion of the guide plate 18 of the guide member 17, and is biased by the solenoid 33 in the direction of contacting or separating from the work surface 2, respectively. As described above, a feed foot drive unit is constructed, and the feed foot 35 presses the work cloth against the work surface 2, transports it in the cloth feed direction F, and returns to the original position after leaving the work cloth.
Second, its effect will be explained.

First, the operator determines the position at which the edge of the work cloth is to be folded, and sets the work cloth so that the regulating part 19 of the guide plate 18 of the guide member 17 is located there. At this time, the guide member 17 and the feed leg 35 are located above the workpiece cloth, and the operating plate 29 of the operating member 25 is located within the hole 5.

Next, the operator urges the guide member 17 toward the workpiece cloth to start the apparatus. At this time, the guide plate 18 is in light contact with the work cloth.

First, the actuating member 25 is raised by the drive of the pulse motor 27, and its actuating plate 29 lifts up the edge of the work cloth.

Next, the pulse motor 23 is driven to move the moving table 24 to the left in FIG.
8, the edges are folded in. Next, the feed foot 35 is urged toward the work cloth and presses the folded work cloth.

Next, the moving table 14 is moved to the cloth feeding side by the drive of the pulse motor 13, and the guide plate 18 is removed from below the two actuating plates. At this time, the work cloth is pressed by the feed foot 35 and therefore does not move. The actuating member 25 is then lowered by the pulse motor 27 and presses the work cloth against the work surface 2 to form a crease.

Next, the moving table 24 is moved to the right in FIG. 1 by the drive of the pulse motor 23, and the two actuating plates are removed from the work surface 2. Next, the actuating member 25 is lowered by the pulse motor 27, and the two actuating plates enter the hole 5, and the guide member 17 is separated from the work cloth and moved in the cloth feeding direction F, so as to lightly contact the work cloth again. Return to the starting position.

After entering the hole 5 of the actuating plate 29, the feed leg 35 transports the work cloth in the cloth feeding direction F by driving the pulse motor 32, leaves the work cloth, and returns to the initial position again. By repeating the above operations, the edges of the work cloth are folded continuously, and the creases are formed in the direction.In the present invention, by transporting the work cloth according to a predetermined pattern, the edges of the work cloth are folded. Creases can be formed along the line, making it possible to handle fabrics of various shapes.

[Effects of the Invention] Since the present invention is configured as described above, the edges of the work cloth are folded in continuously, so that changes in the shape of the work cloth can be accommodated.
