Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a method and apparatus for continuously manufacturing sandwich-like confectionery, and more specifically, to a method for continuously manufacturing sandwich-like confectionery such as chocolate sandwich and cream sandwich from confectionery dough to finished product. The present invention relates to a method and an apparatus for automatically and continuously producing the same.

Conventional technology Traditionally, sandwich-like confectionery has been produced by baking confectionery dough whose main ingredient is small V flour or the like into a plate shape, and sandwiching a filling such as chocolate or cream between the plate-shaped confectionery pieces. , has been popularized. In this sandwich-like confectionery, the taste of the contents such as chocolate and cream is softened by the taste of the confectionery pieces on both sides, resulting in an excellent flavor and taste. It is also said that because the contents of chocolate, etc. are not exposed to the outside, it is easy to eat and handle.

However, the problem with sandwich-like sweets is that the pieces are made of flour, etc., and the filling is made of chocolate, etc., so even if the filling is sandwiched between the pieces,
It is difficult to integrate the confectionery pieces and the contents on both sides.

In this regard, it is possible to interpose an edible binder between the confectionery pieces and the filling, but for example, there is no edible binder that does not impair the flavor and taste of the chocolate filling, so if it is interposed, the flavor will be affected by the edible binder. Destroyed by a large cloth.

From this point of view, it has become necessary to directly integrate the confectionery pieces and the contents without intervening an edible binder, and various improvements have been made. However, these improvements have been proposed on the premise that the sandwich-like confectionery will be manufactured manually. Therefore, these improvements cannot be directly adopted for automation and continuity in order to reduce product costs and improve workability. Furthermore, in order to achieve automation and continuity, it is necessary to review the integration technology accordingly.

That is, Japanese Patent Publication No. 56-28495 discloses one technique for integrating confectionery pieces and chocolate filling. This technique involves first cooling the chocolate to 0°C and heating the confectionery pieces to about 200°C, then
Welding is achieved by instantaneously melting the cooled chocolate on the heated confectionery piece by the heat of the confectionery piece. However, although this method can be carried out manually, the work of placing chocolate cooled to 0°C on top of confectionery heated to 200°C is cumbersome and requires a lot of work for workers. This will require harsh labor.

Furthermore, in order to achieve automatic continuity, a heating device that heats the confectionery pieces to 200°C and a cooling device that cools the chocolate to 0°C are required. Furthermore, these devices themselves are large and complex, and it is extremely difficult to incorporate them into a line from baking the confectionery dough to inserting the filling. An automated line for consistently producing sandwich-like confectionery has not yet been proposed.

Problems to be Solved by the Invention The present invention aims to solve the above-mentioned drawbacks, and specifically, it aims to solve the above-mentioned drawbacks, and specifically, it aims at solving the above-mentioned drawbacks. Heat, especially the residual heat remaining on the back side of the confectionery pieces, is used to integrate them with the chocolate inside.Furthermore, in a continuous line, the aligned confectionery pieces are partly turned inside out using a reversing device. We propose a method and an apparatus for continuously and automatically manufacturing sandwich-like confectionery by passing through the other parts without inverting them.

Means for solving the problem and its operation, namely, the method of the present invention consists of arranging and baking plate-shaped confectionery pieces on an endless baking plate, and then inverting a part of the confectionery pieces every other row, Then, among these confectionery pieces, the contents are placed on the inverted confectionery pieces that have been turned inside out, and then the uninverted confectionery pieces are placed on top of the contents, and then the method is further cooled. The best equipment to use when performing this is
At the tip of a confectionery piece baking device that automatically bakes plate-shaped confectionery pieces, a reversing device is placed at the tip of the confectionery piece baking device that inverts some of the confectionery pieces and allows other confectionery pieces to pass through without being reversed. A conveyor and a cooling conveyor are connected to the conveyor, and the contents are placed on the back side of the inverted confectionery piece on this conveyor! ! The present invention is characterized in that a confectionery piece stacking device and a confectionery piece stacking device for stacking other confectionery pieces that have passed without inversion on top of the contents are sequentially provided toward the downstream side.

The operation of these means will be explained in more detail with reference to the drawings as follows.

Note that FIG. 1 is a layout diagram of an example of an apparatus for carrying out the present invention, FIG. ), (b) and 1, -(C) are explanatory views when a part of the confectionery piece is inverted in the inverting device and the other part passes through.

First, in FIG. 1, reference numeral 1 denotes a confectionery piece baking apparatus that automatically and continuously bakes confectionery pieces from confectionery dough, and this confectionery piece baking apparatus 1 is constructed as usual. That is, the grilling plate 11 is wound around the roller 13 in an endless manner, and while the grilling plate 11 moves continuously or intermittently, it passes through a firing stage (not shown) and is heated by an electric or gas heating source. Confectionery dough is baked and plate-shaped confectionery pieces 2 are continuously or intermittently discharged. A transfer conveyor 3 is provided at the tip of the confectionery piece baking device W1 as desired, and the plate-shaped confectionery pieces 2 are transferred onto this transfer conveyor 3. Piece of sweets like a mouth 2
When baking the confectionery pieces 2, the confectionery dough is arranged on the confectionery piece baking device 1 and then on the endless baking plate 11 at a certain interval, and baked in this state to form the confectionery pieces 2. Transfer onto transfer conveyor 3.

Next, a reversing device 4 is provided at the tip of the transfer conveyor 3 (or if the conveyor 3 is not provided, the tip of the confectionery piece baking device @1). As will be explained in detail later, this reversing device 4 is used to invert some of the confectionery pieces 2 arranged in sequence and allow other parts to pass through as they are. Let it pass as is.

That is, the reversing device 4 does not reverse all of the confectionery pieces 2 sent from the transfer conveyor 3. That is, some pieces of sweets are turned over and turned over, and other pieces are passed through as is.

To configure this, as shown in part in FIG. 2, the reversing device H4 includes a rotating shaft 41 that rotates intermittently or continuously, and a rotating shaft 41 that extends in one direction around the rotating shaft 41. A holding part 42 that holds some pieces of confectionery and a sliding part 43 that extends in the other direction and allows other pieces of confectionery to slide and pass through without being turned over are provided. To explain in more detail, the rotating shaft 41 is arranged in the width direction of the transfer conveyor 3, and the holding part 42 extending in one side direction of the rotating shaft 41 is a bifurcated rod-shaped member 42a as shown in FIG. 3(a). , 42b. Further, the sliding portion 43 extending in the other direction of the rotating shaft 41 is constructed by arranging bar-shaped members 438 in a slatted shape, and one surface of the holding portion 42, for example, a surface formed by the rod-shaped member 42a, and the sliding portion 43
The sliding surface of the rod-shaped member 43a and one surface formed by the rod-shaped member 43a are arranged so as to form the same plane. Furthermore, a part of the rotating shaft 41,
In other words, the portion 41a located on the same plane is partially cut out to be flat.

With this structure, when the holding part 42 is in the position shown in FIG. 3(a) with respect to the transfer conveyor 3, the confectionery piece 2 slides from the transfer conveyor 3 and enters the holding part 42. At this time, when the rotating shaft 41 rotates in the direction of the hour hand, the 2° confectionery piece in the holding part 42 is lifted, reversed, and turned inside out.
The turned over confectionery piece 2 passes through a receiver 5 as desired,
It is transferred onto a conveyor 6, which will be described later. In response, the rotating shaft 41 rotates further, and one surface of the holding part 42 and the sliding part 4
When the confectionery pieces 2 reach the state where they form the same plane with the sliding surfaces of the transfer conveyor 3 (see Fig. 3 (C)), the confectionery pieces 2 sent from the transfer conveyor 3 slide on these surfaces and remain as they are, that is, front and back. passes through without being reversed and reaches a conveyor 6, which will be described later.

The conveyor 6 is configured as a conveyor capable of conveying the confectionery pieces 2 as in the conventional example, but the confectionery pieces 2 are arranged in a reversed state in every other row on the conveyor 6 and are sent sequentially. A content placement device 7 is provided approximately in the center of the conveyor 6 across its width. The intermediate loading device 7 includes a moving conveyor 71 provided in the width direction and this moving conveyor 7.
1 and a contents suction device 72 provided in connection with the contents suction device 72. The contents suction device 72 sucks and lifts the contents 8 such as chocolate and cream that are sent in the width direction by the moving conveyor 71 using air pressure, and transfers them onto the inverted confectionery piece 2a as shown by the arrow in FIG. In other words, it is placed on the back side. Also, adjacent to the contents placement device 7, there is a confectionery piece stacking device on the downstream side thereof! 9 will be provided. Similar to the contents suction device 72, this stacking device t9 is a device that uses air pressure to suction and lift the confectionery pieces 2b that have passed through without being turned over, and places them on top of the contents 8. This device can be constructed as conventional. In this way, the uninverted confectionery piece 2b and the inverted confectionery piece 2a are sequentially placed on the filling device! 7 and the confectionery piece stacking device 9, the filling 8 is sandwiched between the confectionery pieces 2a and 2b, forming a sandwich-like confectionery 10. When this sandwich-like confectionery 10 reaches the cooling conveyor 12 on the downstream side, it is cooled and integrated.

Although it is preferable that the cooling conveyor 12 cools the parts as instantaneously as possible, in the present invention, the parts can be integrated even if they are cooled by natural cooling or air cooling.

In addition, as described above, when manufacturing a sandwich-like confectionery, the confectionery piece is placed on the inverted confectionery piece 2a within 15 seconds at most, preferably within 12 seconds after baking.
In other words, it is preferable to put the filling 8 such as chocolate on the back side.

Further, after placing the filling, it is preferable to place the confectionery piece 2a as it is on top of the filling within about 8 seconds.

In other words, in order to integrate the confectionery pieces and the contents,
As mentioned earlier, in the conventional example, the contents such as chocolate are cooled to 0°C, the confectionery pieces are heated to around 200°C,
Due to the temperature difference between the two, the chocolate inside is instantly melted to create a separation between the confectionery pieces and the inside. In contrast, in the present invention, the confectionery pieces are neither heated nor the contents cooled, and the baked confectionery pieces are simply turned over and the chocolate or other contents are placed on top to integrate them. Measure. That is, in the present invention, when confectionery pieces are baked on an endless baking board, the confectionery pieces are cooled after passing through the baking chamber, and the temperature of the confectionery pieces does not decrease to 200° C. even in the baking chamber. However, the degree of cooling after passing through the baking chamber is small because the surface that is exposed to the outside air is thick (and the back side is not exposed to the outside air), so the degree of cooling is small. For example, the back side of the piece is 7
It has been found that if the temperature is maintained at around 0°C to 40°C, and the contents of chocolate or the like are at room temperature, good welding can be achieved. Therefore, if the time when the filling is placed from the outlet of the confectionery piece baking device is about 15 seconds or less, even if the back side of the inverted confectionery piece is exposed to the outside air, the temperature of the back side will be maintained at 40°C or higher. It is sagging,
Simply placing the chocolate or other filling on top of this will be sufficient for welding, and (in addition, the melting of the filling will be limited to the area where it comes into contact with the confectionery wrapper), so the shape of the filling will not be damaged and the melting will be good. In addition, the back side of the uninverted confectionery pieces comes in contact with the outside air for a short time when passing through the inverting device and is cooled, but the extent of this is extremely small, and even on the conveyor, the back side is completely exposed to the outside air (outside air). For this reason,
There is almost no temperature drop on the back side of the confectionery piece that is not inverted compared to the back side of the confectionery piece that has been inverted (as it passes through the filling placement device).
i8 seconds to around 5 seconds, the back surface is maintained in the range of 40°C to 50°C. Therefore, by simply placing it on top of the filling, the back side of the confectionery piece that does not turn over allows the filling to be placed in the vicinity of the contact area, and a sandwich-like confectionery can be obtained as a single piece.

Furthermore, for subsequent cooling on the cooling conveyor, it is sufficient to allow the material to cool while passing on the conveyor. The reason for this is that, as mentioned above, the cooling by the back sides of both confectionery pieces is limited to the area where the contents contact, so the welded area is extremely small.
This is because the product quality can be maintained without damaging the shape of the contents even when left to cool. This is one of the features of the present invention, and if there is a large temperature difference between the confectionery pieces and the contents as in the conventional example, the contents will melt more than necessary during welding.
The product shape is severely damaged. However, depending on the type of chocolate or cream in the contents, the degree of melting during welding may be extremely large. In this case, forced cooling during the passage of the cooling conveyor
Even if the melted contents are small, they will not sag and will not lose their shape.

The contents above are mainly chocolate,
Although the explanation has focused on cream, any other material can be used as long as it can be melted at a temperature of 40° C. or higher.

<Effects of the Invention> As explained above, the present invention provides a method and apparatus for continuously manufacturing sandwich-like confectionery, in which plate-shaped confectionery pieces are arranged and baked on an endless baking plate, and then the confectionery pieces are baked. Flip every other row, then out of these candy pieces,
It is characterized in that the filling is placed on the inverted confectionery piece that has been turned over, and then the uninverted confectionery piece is placed on top of the inside out, and then the confectionery piece is cooled. Therefore, sandwich-like confectionery can be produced consistently from confectionery dough, and in particular, after baking the plate-shaped confectionery pieces on an endless baking board, the filling can be placed on the inverted confectionery pieces within a maximum of 15 seconds. The contents may not only melt when they come into contact with the confectionery pieces, but may also weld together, and are then left to cool.
Sandwich-like confectionery of excellent quality can be continuously produced with high yield.
