Reference numeral 7 mainly comprises an endless belt 28 and a pressing member 29. The endless belt 28 is flexible, is arranged parallel to the plane of each belt conveyor 12, and is movably supported by a base (not shown).

The pressing member 29 is arranged inside the endless belt 28 on the side closer to the upper surface of each belt conveyor 12, and is arranged vertically movable inside the lower belt 28a. The vertical movement of the pressing member 29 causes the link lever 31 to be moved by a driving source 32 such as a cylinder.
Done through. The doub of the endless belt that occurs when the pressing member moves up and down is absorbed by the sprinkle 30 interposed between the endless belts. The pressure flattening means 17 configured as described above is intermittently transferred in synchronization with the belt flattening means 17 a, 12 b, 12 c, 12.
It is arranged corresponding to the stop position of the circular melon-side cloth M placed on d.

Belt conveyors 12a, 12b, 12c,
The discharging means OT is connected to the end of 12d on the discharging side in the transfer direction F2, and the tip of this discharging means OT is connected to each annular frame 14 which is the supply position in the next step. The discharging means OT is composed of an opening / closing plate 18 configured to be openable / closable between a dotted line and a solid line by a drive source (not shown), and a plate-shaped chute 19 having a large number of air holes (not shown). Further, the opening / closing plate 18 is normally in a closed state with its tip end connected to the discharge end of each belt conveyor 12a, 12b, 12c, 12d.

When the core material C on the belt conveyor 6 is not positioned immediately below the annular frame 14, this is detected by a sensor (not shown), and the open / close plate 18 is raised to the position shown by the dotted line to open it. . As a result, the melon-side material M that has been transferred by the belt conveyors 12a, 12b, 12c, 12d but cannot be transferred to the shutters 13a, 13b is the belt conveyors 12a, 12b,
It falls on the return conveyor 35 for collecting the melon side dough, which is arranged at the lower stage of 12c and 12d. The dropped melon-side dough M is returned by the return conveyor 35 and is collected in, for example, the hopper 16.

A large number of air holes (not shown) are formed in the plate-shaped chute 19, and the air pressure ejected from the air holes causes the chute 19 to slide down on the upper surface of the chute 19 when the opening / closing plate 18 is closed. It is possible to reduce the sliding resistance between the flat-shaped melon-side material and In addition,
A dusting device 33 is arranged on the upstream side of the hopper 16 of each of the belt conveyors 12a, 12b, 12c, and 12d, and by this, dust is sprinkled on the belt to prevent the melon-side fabric from adhering to the belt. Can be prevented.

Similarly, with respect to the running direction (arrow direction) of the endless belt 28 in the pressing and flattening means 17 described above,
By providing the dust-dispersing device 34 on the upstream side of the pressing position and scattering the dust on the surface of the endless belt 28, it is possible to prevent the melon-side fabric from adhering to the endless belt 28 during the pressing. Thus, the belt conveyors 12a, 12
Each melon side fabric M transferred by b, 12c, 12d
Is slidably dropped on the open / close plate 18 and the chute 19 in the closed state by its own weight and positioned in each annular frame 14 of the mounting means 2a, and at the same time, the shutters 13a, 1 in the closed state.
It reaches and is supported by the upper surface of 3b.

That is, as described above, this position is directly above each core material C on a diagonal line that is offset by one pitch for each row of each core material C that is accurately aligned on the belt conveyor 6. It corresponds. Therefore, the shutter 13a,
When 13b is opened to both sides, the pressing member 15 is simultaneously actuated, and the pressing member 15 pushes the pressing head 15a downward, so that the melon-side material M on the shutters 13a and 13b is moved to the belt conveyor 6. It can be flexibly placed on top of the core fabric C. In this way,
Each core material C covered with the melon-side material M is intermittently transferred by the belt conveyor 6 to the next step, that is, the encapsulation step 3.

Next, the wrapping device 3a for carrying out the wrapping process of wrapping the melon-side cloth M on the upper surface of the core cloth C on the outer circumference of the core cloth C will be described. The encapsulation device 3a is configured such that a plurality of cups 25 having open bottoms are supported by a plurality of crossbars 24 so that the cups 25 can be moved up and down, and the cups 25 are elastically urged downward by springs (not shown). . The plurality of cups 25 of the encapsulation device 3a are placed on the wide belt conveyor 6 on which the melon-side material M is placed in the same manner as in the molding step 1 described above, and are continuously arranged at equal intervals in each of a plurality of rows. The core fabrics C are arranged in correspondence with each other.

The crossbar 24 is fixed at its both ends to a pair of frames 21a, 21b arranged in parallel along both upper sides of the belt conveyor 6 in the transfer direction to form a frame body 20. Frame body 20 configured in this way
Are supported by well-known eccentric movement mechanisms 23a and 23b provided on both upper surfaces in the transfer direction of the belt conveyor 6 of the base B supporting the belt conveyor 6. The eccentric movement mechanisms 23a and 23b can perform the eccentric movement in the horizontal plane in a state where the frame body 20 is lowered and the cup material 25 is placed on the core material C on which the melon-side material M is placed.

The cup 2 supported by the crossbar 24
5 is a crossbar 24 as the belt conveyor 6 advances.
Each of the cups 25 has a different shape. Therefore, the moving core material C on the belt conveyor 6 is sequentially rounded together with the melon-side material M applied on the core material C by the eccentric movement of the plurality of cups 25 applied on the belt conveyor 6. . At the end, almost the entire peripheral surface is wrapped, leaving the bottom surface of the core cloth C, and a beautiful round-shaped wrapped product S
(Melon bread) is obtained.

Although the method for producing the melon bread has been described in the above embodiment, the core dough C can be replaced with bean paste, and the melon-side dough M is formed of a fermentable dough to form the core dough C. It is also possible to manufacture bean jam bread by covering the entire circumference. In addition, in the molding step 1 shown in FIG. 2, the spray nozzle 26 is provided at the bottom of the belt conveyor 5.
a is disposed toward the surface of the belt 5a. By spraying water in the form of spray from the spray nozzle 26a onto the surface of the belt, each core material C placed on the belt 5a is transferred onto the belt 6a of the next belt conveyor 6 when the belt is transferred. 5a can be easily peeled off.

Similarly, on the upper surface of the belt 6a on the inlet side of the belt conveyor 6, a spray nozzle 26b is arranged toward the upper surface of the belt 6a immediately before the next mounting step 2.
By spraying water in the form of spray from the spray nozzles 26b onto the core fabrics C on the belt conveyor 6, the flat melon-side fabrics placed on the core fabrics C can be reliably attached. There is.

Although the present invention has been described above, it is needless to say that the present invention is not limited to the embodiments and various other modifications can be made without departing from the essence thereof. . For example, in the present embodiment, the shutters 13a and 13b of the mounting device 2a for covering the flat cloth C on the belt conveyor 6 with the flat melon-side cloth M are arranged obliquely with respect to the transfer direction of the belt conveyor 6. However, this shutter can be arranged in a direction orthogonal to the transfer direction of the belt conveyor 6.

In this case, the belt conveyor 12 is provided on the conveyor 6 to form a two-story structure. In this case, it is sufficient to provide one common wide belt conveyor without providing a large number of narrow belt conveyors. Further, in the specification, the term melon bread is used, but this is merely an example, and substantially means a product having a core material and an outer material covering the core material.
