The separation plate 52 can be moved by a driving means (not shown), moves upward after moving up from the standby position, moves horizontally after passing through the rear end of the tubular fabric 1, and then moves in the opposite direction. Driven to return to the standby position.

The apparatus of the present invention configured as described above is configured so that the entire apparatus can move in the direction of coming and going with respect to the sewing machine, that is, in the front-rear direction. The whole can be moved in the direction.

Next, the operation of the device of the present invention will be described. First, the apparatus of the present invention and the sewing machine are brought close to each other, and the moving frame 10 is moved to the right to prepare for setting. Next, as shown in FIG. 2, the cylinder rod 13a of the cylinder 13 is advanced. At this time, the plate material 22 of the gripper 20 is kept parallel, and when the needle cloth 21 pierces the flat tubular material 1 placed at the material placement position A, the plate material 22 is spread. Thereby, the upper surface side of the cylindrical fabric 1 located on the uppermost stack is gripped.
Then, the cylinder material 13 is slightly retracted to raise the tubular material 1 to a predetermined height. At this time, the tubular fabric 1 is sprinkled by the gas ejected from the gas ejector 39, particularly the lower surface side is wavy, and the tubular fabric 1 is naturally opened by this operation. In the case where the inner surface of the tubular fabric 1 is made of a material that is easy to separate, gas ejection is not required. Alternatively, the installation of the gas ejector 39 is unnecessary.

Thereafter, as shown in FIG. 3, the upper gripping tool 37 provided in advance so as to match the predetermined height is moved to the left by the cylinders 31 and 33, and is gripped by the gripper 20 to open the mouth. The upper edge of the cylindrical fabric 1 is gripped. Then, the fourth
As shown in the figure, the cylinder 38 is actuated to move the two upper and lower grippers 37 in the direction of separation, that is, the gripping tubular fabric 1 is pulled in the lateral direction, and the lower surface side is tensioned horizontally. State, that is, the height position on the lower surface side is a predetermined height, after that, the lower gripping tool 51 provided in advance at this predetermined height,
It is moved to the left by the cylinders 41 and 43 to grip the lower edge of the tubular fabric 1.

When the lower gripper 51 grips the lower edge, the cylinder
50 is driven to lower the lower gripping tool 51 slightly, and the cylinder 38 is driven to slightly move the two upper gripping tools 37 toward each other. As a result, as shown in FIG. 5, the cylindrical fabric 1 is changed from a state of substantially one horizontal character to a state in which a mouth is opened in a rectangular shape.

When this operation is completed, the upper and lower grippers 37, 51 are moved forward. At this time, the separation plate 52 is raised to a predetermined height slightly lower than the lower gripping tool 51 as shown in FIG. 6, and then leftward from the broken line state to the solid line state (intermediate state). Move horizontally toward. In other words, the operation of the separating plate 52 separates the tubular fabric 1 held by the upper and lower grippers 37 and 51 from the tubular fabric 1 which is the next uppermost product under the tubular fabric 1, and separates the upper and lower tubular fabrics. The lower grippers 37, 51 adhere to the cylindrical fabric 1 moved to the right, thereby preventing the next uppermost tubular fabric 1 from moving.

As a result of the rightward movement, the rotary edge guide 3 and the cylindrical body 4 of the sewing machine as shown in FIG. 7 enter the inside of the cylindrical cloth 1 in a state where the mouth is opened in a rectangular shape. In this state, the plates 37a and 51a of the upper and lower grips 37 and 51 are opened and the tubular fabric 1 is released. As a result, the tubular fabric 1 is set on the rotary edge guide 3 and the tubular body 4 as shown in FIG.

The set tubular material 1 is used as a rotary edge guide 3
Is moved in the front-rear direction by the endless belt 3d of the sewing machine, the cylindrical fabric 1 is positioned below the needle drop 101 of the sewing machine, the position is adjusted, and then the rotary shaft 3a is rotated to rotate the rotary edge guide 3 When the needle is rotated in the circumferential direction, the needle drop 101
, The tubular fabric 1 is sewn.

Then, when the sewing is completed, the sewing machine and the apparatus of the present invention are moved in the separating direction, respectively, and the endless belt 3d of the rotary edge guide 3 is rotated to drop the tubular fabric 1 from the fabric support 2 so that the fabric support 2 is dropped on a belt conveyor (not shown) below.

Thereafter, the sewing machine and the apparatus of the present invention are respectively moved in the approaching direction to prepare for the next set, and the above-described operation is repeated.

In the above embodiment, the upper and lower gripping tools and the fabric support of the sewing machine are brought close to each other to mount the cylindrical fabric, but the present invention is not limited to this, and the fabric support is fixed. So that the upper and lower grips approach the fabric support, or vice versa, fix the upper and lower grips and move the fabric support closer to the upper and lower grips. Of course, it may be possible.

Further, in the above-described embodiment, the case where a plurality of tubular fabrics 1 are stacked and placed at a predetermined position is described as an example,
The present invention is not limited to such a case, and can be applied to a case where the cylindrical dough 1 is placed on a belt conveyor and conveyed one by one. In this case, the separation plate 52 is used. It is possible to eliminate the need for installation.

Further, in the above embodiment, the apparatus of the present invention is applied to the cloth support having the rotary edge guide 3 and the cylindrical body 4, but the apparatus of the present invention applies the cylindrical cloth to another cloth support. The case is also applicable.

In FIG. 1, the moving frame body 10, the frame portion 10b, the support rod 12, the cylinder 13, the cylinder rod 13a, the gripper (20), the plate material (22), and the like are used for the cloth gripper of the present invention. Similarly, a gripping device 30 including a gripper mounting member 35 and an upper gripper 37 and the like, and an upper opening gripper with an upper guide rod 15, sliders 32 and 34, a guide rod 36, a cylinder 38, and the like. Are configured, and further, the grip mounting members 45, 47
And a lower gripping device 40 including a lower gripping tool 51 and the like, and a lower guide rod 15, sliders 42 and 44, guide rods 46 and 49, a cylinder 48,
50 and others constitute a lower opening gripping means.

In the above embodiment, the gas ejector 39 and the separation plate 52 have been described. However, these are not indispensable for the configuration of the present invention.

Effects of the Invention As described in detail above, according to the present invention, only the upper fabric of the tubular fabric stacked at the predetermined fabric placement position is gripped, the mouth is opened, and the mouth is further opened. The upper and lower edges of the opening are respectively gripped with grippers and expanded in the left-right and up-down directions, whereby the mouth of the tubular fabric can be greatly expanded in a rectangular shape, and this state can be achieved. The cylindrical dough can be set on the dough support while maintaining the condition.

Therefore, according to the apparatus of the present invention, the setting to the fabric support can be performed smoothly and reliably, and the type (particularly size and elasticity) of the tubular fabric to be set is changed during the work. Even if there is a problem, it can be dealt with without replacing the parts, and the troublesome work of replacing the parts every time the kind of the tubular material changes is released. That is, according to the present invention, it is possible to provide an automatic dough setting device capable of automatically and more appropriately executing the dough setting operation.

It should be noted that “gripping” in the present specification is used in substantially the same meaning as “sandwich”.
