DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the production of foods in which the inner packaging material is wrapped in an outer packaging material such as anpan, bun, hamburger, cookie, etc. The present invention relates to a bar-shaped cloth wrapping and cutting apparatus provided with a drive mechanism capable of easily responding to changes in size and material.

[0002]

2. Description of the Related Art As a prior art relating to the present invention, there is one shown in FIGS. In this method, square pieces C are assembled on an opening B provided in a housing A so as to form a box, and the box is opened and closed by moving each of the square pieces C in synchronism, thereby enclosing the rod-shaped cloth passing therethrough. This is for cutting. One end of the square piece C is pivotally supported by an action pin D provided on the housing A, and a drive pin G protruding from a drive ring F is engaged with an elongated hole E provided at a lower portion near the center of the square piece C. Therefore, when the drive ring F reciprocates in a predetermined range, the opening and closing of the enclosure is repeated around the action pin D as the rotation center. In this case, FIG. 11 shows a drive transmission method for rotating the drive ring F within a predetermined range. A pin H protrudes from a lower portion of the drive ring F, and the pin H is fitted into a slot-shaped guide portion K of an arm J that reciprocates together with the drive transmission arm I. Since the drive ring F is rotatably supported by the housing A, the drive ring F reciprocates via the pin H by the reciprocation of the drive transmission arm I. The reciprocating motion of the drive transmission arm I has a cam follower O that engages with a cam groove N of a cam plate M provided at one end of a drive shaft L as shown in FIG. This is realized by supporting a drive transmission arm at the other end of the moving arm P.

[0003] In the case of producing a product using this conventional apparatus, it is necessary to select an optimal square piece according to the type of bun, daifuku, anpan, french bread or fish meat product. For example, in order to obtain properties such as viscoelasticity of a rod-shaped dough and a desired product shape, a dough pressing surface is a flat surface, and Japanese Patent Publication No. Sho 63-29979 or Japanese Patent Publication No. 5-9051, or a dough pressing surface is provided in a convex shape. Japanese Patent Publication No. 5-53453 and Japanese Patent Application Laid-Open No. 4-1844 can be selected. When the above selection is made, the shape of the box through which the bar-shaped dough passes changes due to the change in the shape of the dough pressing surface, so that when the same bar-shaped dough is used, the sliding or swinging range of the wrapped cut piece is changed. Needs to be increased or decreased. In the past, this square piece or the housing in which the square piece was stored was replaced, and even the cam plate, which determines the sliding or swing range of the square piece, was replaced. It is a cause to lower the sex.

[0004] A similar problem has arisen when the size of the supplied bar-shaped dough is changed. For example, when changing the diameter of the bar-shaped cloth to a larger diameter, it is necessary to replace the rectangular piece with a large opening / closing stroke with a cam plate for opening and closing. Further, when changing the diameter of the rod-shaped cloth to a smaller diameter, the use of the same cam plate increases the gap between the rod-shaped cloth and the rod-shaped cloth. Further, when the productivity is increased, the frictional heat generated by the sliding with the adjacent rectangular pieces becomes unnecessarily large, which hinders the smooth opening / closing operation. From the above, conventionally, when changing a product from a large one to a small one or from a small one to a large one, the cam plate must be replaced in advance to change the opening diameter.

[0005]
