DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing foods such as buns and ohagi, and more particularly to an apparatus for encapsulating and cutting food materials supplied in a continuous rod-shaped food body.

[0002]

2. Description of the Related Art Conventional wrapping and cutting techniques relating to these are described below.
The applicant has already filed various applications, for example, Patent No. 160
No. 7849, No. 1563179, Japanese Patent Publication No. 4-61
2. Patent application publications 4-121138 and 4-144
630 and the like, and production is facilitated by these devices. In these cutting techniques, plastic is generally used to prevent sticking of food materials during cutting, so the fitting of these parts becomes tight due to the thermal expansion of the cutting part due to long operation. In this case, the applicant of the present invention gives a play (gap) to the sliding surface of the cutting section in advance to prevent the cutting operation from becoming too tight, and a shim according to the change in the gap. Adjustment and clearance adjustment device (1385
No. 83).

[0003]

As described above, in the prior art, the sliding surface of the cut portion is provided with a gap so that the fitting is not tight, and the fitting is adjusted according to the change in the clearance. This adjustment has to be performed visually by the operator each time, and the operation must be stopped, which is a complicated operation that requires constant attention. In addition, when this work is performed or the fitting of the sliding surfaces becomes tight, burning of the sliding surfaces occurs immediately and the operation must be stopped. Also gap (play)
When the product was too thick, a good product could not be manufactured because the product to be cut was damaged due to the gap.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is a means for continuously supplying a bar-shaped food body. The annular assembly 8 is formed by combining three or more block pieces having two adjacent side surfaces as sliding surfaces and repeating the transition from the open state to the closed disappearance state of the space 7 with the sliding surfaces in contact with each other. Means for simultaneously sliding the block pieces in a housing for accommodating the annular assembly 8, wherein the slide face of the at least one block piece facing the surrounding space 7 is provided on the sliding surface. The conventional problem can be solved by providing a slider independent of the main body and providing a means for pressing the slider toward the tip of the block piece. This eliminates the need for adjustment of the gap, and achieves an appropriate fit of the sliding surfaces to enable continuous operation without any problem. Can be done with

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below. FIG. 1 is a plan view of a first embodiment of an envelope cutting apparatus to which a block piece according to the present invention is mounted, and FIG. 2 is a side view thereof. FIG. 3 is a plan view of the second embodiment. Reference numeral 1 shown in FIG. 2 is a means for continuously supplying the bar-shaped food body 2. An annular assembly 8 is provided coaxially at the lower portion of the continuous supply means 1 and repeats the transition from the open state to the closed state of the surrounding space 7 at the center. The annular assembly 8 is provided with five block pieces 3 and two drive block pieces 31 each having two adjacent side surfaces as sliding surfaces, assembled in an annular shape, and loaded into the housing 4.

The opening and closing of the enclosing space 7 is performed by driving the driving block piece 31 accommodated in the housing 4 by the driving pin 5 which is moved by a known cam mechanism.
As shown in FIG. 4, the drive block piece 31 includes a block piece main body 32 and a slider 33, and is provided with a protruding pin 34 on the block piece body 32. The pin 34 is inserted into the slider 33. A hole 35 and a spring 36 are provided in the hole 35. Since the slider 33 fits into the groove 37 (FIG. 5) provided in the block piece main body 32, the sliding direction is only the direction of the cutting edge 38 of the slider 33 (arrow).
Is regulated. The annular assembly 8 is accommodated in the housing 4 by the drive block piece 31 and the other block pieces 3, and the slider 33 of the drive block piece 31 is constantly pressed by the spring 36, and the cutting edge 38 is adjacent. Is pressed into contact with the block piece 3 of FIG. The block pieces 3 are sequentially and interlocked and pressed by the pressure contact of the slider 33, so that the gap between the block pieces disappears. 3 and 6 show an embodiment in which the wrapping and cutting devices are provided in multiple rows. In this case, one annular assembly 8 is provided with two drive block pieces 61 corresponding to the drive mechanism. Also in this case, the slider 63 of the drive block piece 61 presses the adjacent block piece under pressure, and the backlash (gap 64) is absorbed by the slider 63 of the two drive block pieces, and the opening and closing becomes smooth. . Opening and closing of the surrounding space 7 can be performed with an appropriate force by adjusting the strength of the spring 65 of the slider 63, so that burning of the plastic does not occur.

Normally, when a drive block piece 61 whose positional relationship is restricted moves, a gap 64 is formed between the drive block piece 61 and a block piece behind the drive block piece 61. Since it is possible, the slider 63 may be prepared in the drive block piece. Further, the block piece 3 and the sliders 33 and 63 of the present invention are one embodiment, and are not limited to this shape. The present invention may be applied to the shape of the block piece of the cutting device shown in the above-described conventional technology. It is possible.

[0008]

As described above, according to the present invention, it is possible to omit the adjustment of the clearance between the sliding surfaces of the block pieces of the cutting device during operation, to eliminate complicated operations, and to enable continuous operation. Was. In addition, since the block pieces are appropriately pressed against each other, there is no gap at the time of opening and closing, and it is possible to eliminate defects in the conventional product molding such as generation of scratches and folds due to the gap in the cutting of the bar-shaped food body.
