Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a forming apparatus for forming twisted pleats on the surface of dough such as buns and breads.

<Prior Art> Conventionally, buns with twist-like pleat patterns, such as Chinese buns, have been known, and the present applicant has filed an application as a means for attaching pleat patterns to these buns. (Patent Application No. 61-34771) This pleating process, which is seen in the manufacture of Chinese man-made clothing, cannot be applied simply by pressing the machine, but when it is steamed and made into a final product, the pattern will not change. Since the pattern almost disappears, and the mechanically applied pattern becomes regular and linear, it is not possible to obtain a natural twisting pattern with the spiral shape that can be obtained by hand.

Therefore, in the past, twist pleats were added one by one by hand, which required a great deal of labor.

<Problems to be Solved by the Invention> The present invention solves the above-mentioned problems, and allows the formation of a natural spiral pattern similar to that produced by hand using a simple device, and allows the product to be steamed. It is an object of the present invention to provide a device that can leave a sufficient twist pattern even after being twisted.

<Means and effects for solving the problem> The present invention combines three or more rectangular pieces having two adjacent surfaces as sliding surfaces, by bringing the sliding surfaces into contact with each other, and combining them horizontally into a ring shape. An enclosure is constructed, a cutout is provided on the sliding surface of each square piece, and a small diameter shaft that is movable up and down and rotatable is provided above or downstream of the enclosure, and the square pieces are slid. When the enclosure becomes smaller, the length of the gap in the sliding surface that is created by the missing part gradually increases, and by using this phenomenon, the folds are pulled out in several strips on the surface of the pressed manju dough. At the same time, as the small-diameter shaft rotates, the small-diameter shaft that comes into contact with the pleats exerts a twisting action, causing the pleats to form a natural twisting pattern in the form of a spiral.

<Example> The pleat forming means of the present invention will be described based on an example. 1 is a square piece having a missing portion 2;
and 4 are sliding surfaces on adjacent sides of the square piece 1. The missing portion 2 is provided in a part of the sliding surface 3.

Reference numeral 5 denotes a chamfered portion at one corner of the square piece 1, where the chamfered portion 5, the missing portion 2, and the sliding surfaces 3 and 4 come into contact with the fabric 8.

6 indicates a framework formed by combining a plurality of the above-mentioned square pieces 1.

7 shows the box created in the center by the frame 6.

When a force is applied in the direction of arrow P shown in FIG. 3, square piece 1 moves in the direction of arrow N, box 7 becomes smaller, and eventually box 7 disappears completely as shown in FIG. It ends up.

At this time, the chamfered portions 5 gather at the center to form a hemispherical depression, and at the same time, radial gaps 30 are generated above this depression.

When the square piece 1 is moved in the direction opposite to the arrow P, the box 7 becomes larger and the gap 30 disappears.

In the first step of the present invention, the movements P and N are used to pleat the fabric 8 supplied to the enclosure 7, and also to pleat the skin 10 in the case of a cloth having an inner wrapping material. produce an effect.

This pleating effect is caused by the sliding surface 4 and chamfered portion 5 of the square piece 1 friction-inducing the surface of the skin 10 due to the movement P, as shown in FIG.
As shown in FIG. 10, the skin 10 is pushed into the gap 30 (arrow M) to form pleats 31.

11 to 13 show an embodiment of the present invention, in which an outer sliding surface 11 is provided on one side of a square piece 1, a framework 6 is housed in an outer frame 12, and adjacent The sliding surfaces 3 and 4 of the square piece 1 come into contact and slide, and the outer sliding surface 11 and the outer frame 12 slide, and a pin 13 is screwed into one place of the square piece 1. A cylinder rod 15 of an air cylinder 14 attached to the outer frame 12 is attached to the end of the pin 13.

An outer frame 12 containing this framework 6 is attached to a frame 29 above the conveyor 26 at a predetermined interval.

Attach the air cylinder 16 hanging down from the top of the frame 29, and attach the cylinder rod 17.
is rotatable, and a gear 18 is pivotally attached to the cylinder 17.

A gear 19 that meshes with the gear 18 is attached to a motor 20 attached to the upper part of the outer frame 12.

A small diameter shaft 21 is pivotally attached to the rotatable cylinder rod 17, and when the cylinder rod 17 is lowered, the small diameter shaft 21 enters the enclosure 7 and its tip 22 touches the fabric 8. It's summery.

On the underside of the conveyor 26, a plate 25 is fixed to the cylinder rod 24 of the air cylinder 23 for raising the conveyor belt so that the products 31 traveling on the conveyor 26 are inserted into the box 7.

The conveyor 26 is operated intermittently by a motor 27, and when a sensor 28 (such as a photoelectric switch) detects that the fabric 8 has arrived below the framework 6 after the product is conveyed, the sensor 28
The drive of the motor 27 is stopped in response to a signal from the conveyor 26, and the operation of the conveyor 26 is stopped.

Next, the operating sequence of this embodiment will be described. When the fabric 8 is conveyed on the conveyor 26 and the sensor 28 detects that it has arrived at the lower part of the enclosure 7, the drive of the motor 27 is stopped based on the detection signal.

The air cylinder 23 is actuated to raise the plate 25 and then stop, supplying the dough 8 to the box 7 waiting in the state shown in FIG.

Air cylinder 14 is actuated to close enclosure 7 and then immediately expand enclosure 7.

The air cylinder 16 is operated to lower the small diameter shaft 21.

The motor 20 is driven to rotate the small diameter shaft 21.

The air cylinder 16 is operated to raise the small diameter shaft 21.

Stop driving the motor 20.

Operate the air cylinder 23 to remove the plate 2.
Lower 5.

The motor 27 is driven to operate the conveyor 26.

This operation is just an example, and the purpose can be achieved even if the operations are performed simultaneously in any other order.

By such an operation, the fabric 8 is inserted into the enclosure 7 formed by combining the square pieces 1, and the missing part of the sliding surface that occurs as the square piece 1 slides and the enclosure 7 becomes narrower. Gap 30 formed as a result
The fabric is sandwiched between the two, and after the length of the sandwiched fabric gradually becomes longer and reaches a predetermined shape, the enclosure is opened, and the small diameter shaft 21 comes into contact with the formed pleats and rotates to remove the pleats. The center part of the pleats 31 is twisted to form a twisted pleat part like 31'.

In addition, as another embodiment, as shown in FIG. 19, by having a hole 32 large enough for the small-diameter shaft 21 to pass through even when the box 7 is closed, the above operating procedure can be carried out; 16 to lower the small diameter shaft 21.

● Operate the air cylinder 14 and close box 7.

- Drive the motor 20 to rotate the small diameter shaft 16, and operate the air cylinder 14 to expand the enclosure 7.

By doing this in place of the above, the fabric supplied to the box 7 first comes into contact with the small diameter shaft 21 and its position is determined, so there is no unnecessary movement when forming the pleats when the box 7 closes, and accurate pleat formation is possible. Become.

Moreover, if the opening/closing operation of box 7 and the lowering, rotation, raising, etc. of the small shaft 21 in the operation procedure are performed simultaneously, the molding time is shortened.

<Effects> As described in detail above, the present invention involves combining three or more rectangular pieces having two adjacent surfaces as sliding surfaces with their sliding surfaces in contact with each other horizontally in a ring shape. is supplied by an extremely simple device by providing a cutout and sliding a rectangular piece of fabric inserted into the box to form pleats on the fabric, and then twisting the pleats using a rotating small diameter shaft. This makes it possible to create swirl-like folds on the surface of the product, and unlike conventional creases that are created by pressing, the creases are formed by pulling on the sandwich. Because of the folds, these folds do not disappear even after fermentation and expansion or subsequent steam treatment, making it possible to create the same natural feel as handmade products. This simplifies the twisting and pleating work that was previously done, and allows for hygienic shaping.

Further, in this embodiment, the recess formed by closing the enclosure is shown in a hemispherical shape, but this is not particularly necessary, and the object of the present invention can be achieved even with a rectilinear recess.

Further, although the framework of this embodiment is shown as having six square pieces, making it a hexagon, the number is by no means limited to six.

In addition, in this embodiment, the small diameter shaft is provided above the enclosure and entered into the enclosure, but this is not necessary, and the enclosure and the small diameter shaft are provided separately, and the folds can be folded by opening and closing the enclosure. This effect is achieved even when the small-diameter shaft twists the folds after the product is released from the framework and moved.
