The device for expanding and changing the direction of a piece of fabric according to the present invention has the above-mentioned configuration (a), and to further explain the operation of the bag according to the present invention based on this configuration, it is as shown in Figure 2F1. Form the dough pieces 2 from the dough sheet 1 by the cutters 4, 4 as follows, and form two groups a of m pieces 2,
b is separated in the process of being transferred from the conveyor 3 to the conveyor 5.

A piece of dough is conveyed by a conveyor 5 and held by a holding device 3.
When reaching the lower part of the conveyor 5, the vertically movable device 10 is activated and the piece of fabric is raised together with the belt of the conveyor 5 by the plate 17. Then, the fabric/fabric piece 2 is locked to each of the holding devices G'i 32, and the holding device 32 is held in place by the fabric because the pantograph device 27 that supports it is expanded laterally by the expanding device 20. Pieces 2 are spaced apart laterally of the conveyor. Next, the rotating device 40 is activated and its shaft 4
6 moves in the longitudinal direction of the conveyor, the rack member 49 is moved, and the holding device 32 is rotated 900 times by the shaft 33.

Therefore, isosceles triangular pieces of fabric 2 that are sent with their bases facing sideways are expanded and aligned by rotation of the holding device 32 with their bases facing the direction of travel of the conveyor. conduct. Then, when the belt of the conveyor 5 is lowered, the piece of fabric 2 held on the holding device 320 and the needle 36
is released from its lock and placed on the belt because the fabric holding plate 37 is pressed by the spring 38. Thereafter, the rotation device 40 and the expansion device 20 are further operated to return the holding device 32 to the temperature shown in FIG. 3.2 (a).

One rotation of the cam 43 of the rotating device 40 changes the direction of group a of the fabric pieces 2 and then changes the direction of group b. Furthermore, the needles 36 formed on the lower surface of the flange 350 , a plurality of pieces are arranged so that both groups of fabric pieces can be properly locked.

This means that the groups of fabric pieces 2 cut from the fabric sheet 1 are divided into two groups, group a and group b, as shown in Figure 1.
This is because the fabric pieces of each group are sent to the point where they are expanded and rotated alternately, so it is necessary to alternately rotate them in different directions and align them. .

In the examples of the present invention, the pieces of fabric are shown as being cut into isosceles rectangular shapes, but the pieces of fabric are not limited to this shape; for example, they may be cut into pentagonal shapes with parallel parts on both sides It can also be applied to objects and other shapes.

In addition, the bank graph device can easily increase or decrease the number of holding devices by changing the number of links introduced, and furthermore, the length of the stroke of the rod 26 can be changed by rotating the rod 26 in a circular motion. Since the distance between the fabric pieces can be changed by the above method, it is possible to easily adapt to changes in the size of the fabric pieces and increases or decreases in the number of fabric pieces.

(Effects) As described above, the present invention uses an interlocking device with a relatively simple mechanism to expand and rotate a piece of dough in a predetermined direction B, and rotate a specific side of the piece of dough in the conveying direction. It is designed so that it can be lined up and sent facing forward.

Even if the size of the fabric pieces, the number of rows, etc. change, it can be easily adapted by adding links to the pantograph mechanism or changing its range of motion.

Furthermore, according to the device U of the present invention, the dough pieces are cut from the dough sheet in the state most suitable for the forming process, so they can be supplied to the automatic forming process such as croissants in the most suitable state, resulting in high quality. It becomes possible to obtain a product with a high quality.

Agent Postal code: 105 Toranomon-chome, Minato-ku, Tokyo No. 29 Toranomon Industrial Pill 5th floor #! Name of the invention column I of specification A #Claims column I Am-6 Contents of amendment The description of the detailed description of the invention is amended as follows. (1) Amend the scope of claims on a separate sheet. (2) The title of the invention is amended to "Device for expanding and changing the direction of a piece of croissant dough." (3) Make the following corrections from line 5 on page 2 to line 8 on page 3. [(Prior Art) As a conventional device for aligning pieces of dough for a croissant-like body,
Such as is disclosed in US Pat. No. 4,575,548. In this process, a continuously conveyed strip of fabric is cut so that the bottom piece of each triangular piece of fabric is parallel to the direction of travel. After that, a fabric holding member for aligning the fabric pieces holds the fabric pieces and pulls them away from the strip of fabric in the direction of movement, and transfers the fabric to a second conveyor that is faster than the conveyor that conveys the strip of fabric. , is characterized in that the distance between each piece of dough is widened in the width direction, and the orientation of the triangular dough piece is rotated 90 degrees so that the bottom side faces perpendicular to the direction of travel. However, in this device, the distance between the dough piece holding members for holding the dough pieces is fixed, so for example, the size of the dough pieces changes and the widthwise pitch of each dough piece changes. If the fabric pieces change, the fabric piece holding member cannot hold the fabric pieces, and as a result, there is a drawback that the fabric pieces cannot be aligned. In addition, in this device, when the dough piece holding member holds the dough piece and transfers it from the first conveyor to the second conveyor, if the dough piece cannot be held securely, the dough pieces are transferred between the first conveyor and the second conveyor. A problem arises in that a piece of fabric falls into the gap between the joints between the two, resulting in loss of the piece of fabric. ”Appendix Claims
