Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wrapping method in the manufacturing technology of sweet breads such as red bean paste, and to improvements in a wrapping device used directly to carry out this method.

Conventionally, in the production of sweet breads such as red bean paste bread, the process of manufacturing sweet breads such as red bean paste bread relies exclusively on human hands, placing a bead on top of a sheet of bread dough by hand or using a depositor, stretching the edges of the bread dough with fingers and pinching them together to wrap the bead. The procedure used was to press the seam down and place it on a baking iron plate, and then bake it after fermentation.

For this reason, it requires an extremely large amount of manpower, and the quality of the product varies greatly depending on the level of skill of the person tasked with the above-mentioned picking work, making it impossible to always expect products of stable quality. There was a problem.

To deal with this, attempts have been made to apply the wrapping technology that has been successful for Japanese sweets such as Daifuku mochi, which is suitable for automatic mass production. The gluten structure of the dough is destroyed through processes such as extrusion through the gaps, so no matter how the dough's raw materials are mixed and how it is made using current technology, the baked product will lose its internal phase. The connections between the tissues are weak, especially one to three days after baking, and these connections rapidly weaken, giving the meat a crumbly, low-quality texture. Since the product is about to reach the customer's hands and eat it, this is a definite drawback as a product.

In order to solve the above-mentioned difficulties in the prior art, the present applicant has spent many years researching and developing a method that can mass-produce sweet bread such as red bean paste bread in a fully automatic manner at a high production speed, and a wrapping machine for the same.

The results of this work have already been reported in 1986-3008 and 1983
5-3197, and in the new method disclosed therein, a rolled plate-shaped bread dough is placed on a dowel stop that is stationary on a conveyor surface or the like during transfer, and then the skirt portion of this plate-shaped dough is The present invention embodies a method for automatically compressing and compressing the edges so that their edges come into close contact with each other, and a unique enveloping device for this purpose.

While this is suitable for mass production of homogeneous, high-quality sweets and breads, when placing a plate-shaped piece of dough on top of the confectioner's bead or on top of the confectioner's bead that has been combined with an oblate, it is difficult to It is difficult to align the centers of the balls, so unless you press the dough pieces to a large extent, the skirts of the dough pieces will hang down evenly and contact the conveyor surface.
It becomes difficult to smoothly press and compress the skirt portion with the finger rod, and as a result of compressing this piece of dough to a large extent, the dough at the top of sweet bread such as red bean paste becomes thin and the dough at the bottom becomes thick. , the texture is poor, the volume is small, and it is easy to produce a product that is not good enough.

In addition, in the method of depositing the bead on a conveyor or covering the bottom surface with an oblate and placing the pressed plate-shaped dough piece on top of the deposit, the supply of the plate-shaped dough piece is transferred to the deposited bead. The rows must be synchronized, but in the equipment used before the shaping machine that presses the dough balls in the current bread making process, that is, the dough ball dividing machine, the rounding machine, and the intermediate aging device (which is allowed to stand for about 15 minutes). Providing a synchronizer requires significant expense and additional equipment.

In order to solve these problems, the present invention, as described in detail below, moves a plate-shaped fabric piece pressed by a shaping machine to a fixed position on a conveyor consisting of a set of two plates on which a large number of underwear can be placed. Place a bead, etc. on this single core, cover the bead with an oblate, and turn the three parts upside down without changing their relative positions to form a finger rod. The purpose of this invention is to provide a technique that enables wrapping by compressing the skirt portion of a piece of fabric.

In addition, a piece of plate-shaped fabric is placed between two plates for underwear, and jam, cream, etc. are deposited on it.
By reversing a single plate, it became possible to make jam bread, cream bread, etc.

A method of placing a plate-shaped piece of dough at a fixed position on a conveyor plate is described in Japanese Patent Application No. 55-28489 filed by the present applicant.

As will be described below with reference to the accompanying drawings showing embodiments of the present invention, in the present invention, bread dough and sweet bean balls are fed onto a plate forming a main conveyor for wrapping, and the underwear is reversible with respect to the other. The plate is constructed so that a set of two plates can be operated, and furthermore, in this case, the plate can be operated with an wafer piece attached to the surface of the conduit or the like.

The overall wrapping apparatus 1 shown in FIG. 1 is viewed in the order of flow of the workpieces: first, a leveling machine 10 rolls and levels bread dough to a predetermined size and shape; is sent to the wrapping process, that is, main conveyor 3
An inclined conveyor-type dough feeding section 11 that feeds the dough on three sides of the main conveyor, a depositor 12 that intermittently supplies a fixed amount of bean paste, etc. from a nozzle 13 to the dough moving on three sides of the main conveyor, and a depositor 12 that intermittently supplies a quantity of bean paste etc. to the dough moving on the three sides of the main conveyor. A wafer supply section 14 that supplies small pieces of wafer; an inversion section 15 that inverts a plate, which will be described later, which is a component of the main conveyor 3 installed on the frame 2 of the wrapping device 1; and forming and wrapping of jam bread, cream bread, etc. Stamping part 16 used for
, an auxiliary conveyor 5 that transfers bread dough such as wrapped apricot jam bread or cream bread from the main conveyor 3 to the shuttle conveyor 6 in response to the operation of the stamping section 16; A vertically movable wrapping part 171 that grips and wraps the bread dough with the gripping member 18 further transfers the wrapped bread dough to the device 1.
It is possible to provide a shell conveyor 6 for sending the product from the container to the next step.

In the apparatus 1, the main conveyor 3 can be driven intermittently by a main conveyor drive motor 4 and by a Geneva mechanism (not shown), and the auxiliary conveyor 5 can also be driven via a suitable transmission mechanism.

The shuttle conveyor 6 moves forward and backward with respect to the running direction of the main conveyor 3, and this is controlled by the shuttle conveyor operating motor 8.
The belt on the shuttle conveyor surface can be moved intermittently and endlessly by a shuttle conveyor belt drive motor.

The gripping member 18 of the packaging section operates on the top surface of the main conveyor 3 when the shuttle conveyor 6 retreats to the right, and operates on the top surface of the shuttle conveyor belt when the shuttle conveyor 6 enters the packaging section 17. It can be done.

2 and 3 show details of the reversing section 15 incorporated in the wrapping device 1 according to the present invention.

As is clear from FIG. 3, the main conveyor 3 consists of rectangular flat plates 37 arranged in series.

The plates 37 are made of metal such as aluminum or plastic, and a set of two adjacent plates constitutes an operating unit in the reversing section 15.
The undergarment piece 40 is in the form of a thin strip made of plastic material, a leaf spring, a rigid woven fabric, etc., and the undergarment piece 40 is fixedly connected with a suitable undergarment piece fastener 41.

This connection has a margin d so that the dough 27 and the conduit 28 can be sandwiched between the parallel plates 37 upon inversion (FIG. 3).

In FIG. 2, the main conveyor 3 is intermittently moved in the direction of arrow A, but the first reversing drive device R1, A second reversing drive device R2 and a third reversing drive device R3 are provided.

At both ends of the plate 37 are arms 24, 24, one end of which is rotatably attached to the pin 23 of the block 22 fixed to the chino 21, and an arm 38, which also serves as a guide.
38 are installed in opposite directions.

The first reversing drive device R1 has a rack 33 extending through a turnbuckle 31 to a rond end extending from an actuator 30 so as to extend and retract, and a rack pinion housing The rotating arm 25 is provided with a pinion 34 that meshes with a rack 33 within the pinion 32 and a pivot arm 25 that is fixed to the pinion 34 and whose tip enters into the guide portion of the arm 38 when the plate 37 is stopped.

Thus, plate 3 attached to arm 24.38
7 can rotate around the pin 23.

That is, bread dough 21 is supplied from a leveling machine 10, and is supplied from a depositor 12 which detects the presence or absence of a piece of dough using a sensor such as a micro switch or phototube (not shown) and deposits a bead or the like onto the piece of dough 2T. When the dotted ball 28 and the oblate small piece 29 supplied from the oblate supply unit are placed on the plate 37 in a stacked state and reach the reversing drive device R1, the actuator 3
0 is actuated, and the rotation arm 25 is actuated by the engagement of the rack 33 and pinion 34, which are assembled into the rack and pinion housing 32 via the turnbuckle 31.

The operating distance of the actuator 30 is set by the stopper 36 as described above.

The pivot arm 25 is attached to a guide 38 attached to a plate 37.
can be lifted and the plate 37 can be rotated about the pin 23 and placed over the adjacent plate 37.

This corresponds to the movement of the arrow f along the travel direction A of the main conveyor 3 in FIG.

Next, a plate 37 sandwiching the bread dough 27, the sweet bead 28, and the wafer 29.

37 is sent to the second reversing drive device R2 by the chino 21 for driving the conveyor 3.

The swing arm 25 of the reversing drive device R2 simultaneously reverses the two plates 37 and 37 by the actuation of the actuator 30, with the plates 37 and 37 overlapping each other, thus sandwiching the dough and the dowel therebetween.

This reversing movement is opposite to the direction of movement of the plate at the location of the first reversing drive (this corresponds to the pivoting of arrow g in FIG. 3).

In this way, the combined object, which had been stacked on the surface of the plate 37 in the order of the dough 27, the bead 28, and the oblate 29, is turned upside down in the order of the oblate 29, the bead 28, and the dough 27, without any deviation in their relative positions. be done.

Next, when this reversed state is sent to the third reversing drive device R3, the arm 25 is activated by the actuator 30 to reverse only the upper plate 37, that is, to arrange it on the main conveyor 3 surface (this is the third reversing drive device R3). (corresponds to the arrow in the figure).

On plate 37, this time from the top, add 271 pieces of dough and 28 pieces of sweet bean paste.
, the oblate 29, and the combined object determined in this order is sent to the wrapping section 17 as it is.

The gripping member 18 acts on the peripheral edge of the skirt portion of the fabric 27 fed into the wrapping section 17 in the manner described above, and grips the peripheral edge of the skirt portion to wrap the envelope 28 and wrap it. As mentioned above, the dough ball that has been wrapped is lifted to the top end while being held by the gripping member, and waits for the tip of the shuttle conveyor to complete its forward movement (movement to the left II+ in the figure). It descends to the top of the front of the shuttle comper, releases its grip, and rises again.

The shuttle conveyor is driven and sends the ball of dough to the right, and its tip retreats to the right.

When the shuttle conveyor reaches the retreat end and, for example, four pieces of dough, a dowel, and an wafer are placed below the gripping member 18, the gripping member 18 descends to the plate surface and compresses the peripheral edge of the dough piece to perform wrapping. .

Regarding the movement of the gripping member 18, Japanese Patent Publication No. 56-3008
It is described in Japanese Patent Application No. 55-3197.

In the example shown in FIGS. 2 and 3 above, it is suitable for the type of sweet bread represented by sweet bean paste, and the bead 28 is attached to the bread dough 2.
The reversing unit 15 operates as shown in FIGS. 4 and 5 for flat, palm-shaped sweet breads such as jam bread and cream bread.

That is, the first reversing drive device R1 is not used for wrapping jam, cream, or the like.

Furthermore, there is no need for small oblate pieces, and the dough feeding section 11 (
In FIG. 1), bread dough 27 is placed on adjacent plates 37.
The dough 27 is positioned so as to be placed on the main conveyor 3 across 37 degrees, and the dough is eccentrically measured (see Figures 4 and 5).In short, the dough 27 is placed between two plates 37. It is folded to enclose jam or cream etc. 42 which is a bead.

In this case, the flexible underwear piece 40 acts as a leaning wall that connects the two plates 37, 37 to help fold the fabric 2T (indicated in the direction of arrow j in FIG. 37 It works to prevent protrusion from the gap.

Immediately after the fabric is folded between the plates by the second reversing drive device R2, the edge of the fabric is not completely joined and is in a half-open state.

Then, after the upper plate 3T is reversed by the actuator 30 in the direction of the arrow in FIG. The parts are pressed and stamped as appropriate to complete the enveloping of the bean ball.

As described above, in the wrapping device of the present invention, the reversing section is made by attaching two plates to each other and performing a reversing operation according to the object to be wrapped between these plates.
It is possible to reliably and quickly continuously process various types of packaged products such as red bean paste, jam, and cream with the same device by simply changing the operation of the reversing section as appropriate, without causing the paste to adhere to the conveyor surface. Since it can be operated and maintained with a small amount of manpower and is hygienic, it is of great benefit to the bread making industry.
