A roller follower 73 is rotatably attached to the upper end of the roller shaft 71, and the pressing roller 75 is rotatably attached to the lower end of the roller shaft 71. A tension spring 77 is attached to the end of the cylinder portion of the fluid pressure cylinder 67 that is not the fulcrum side from the inside of the stand member 21.

  In the initial position of the fluid pressure cylinder 67 shown in FIG. 4, the moving direction of the cylinder rod 69 (the longitudinal direction of the cylinder rod 69) is shifted from the center of the core member 23. In other words, the moving direction of the cylinder rod 69 at the initial position and the radial direction of the core member 23 with respect to the axial center are arranged at positions that intersect. When the cylinder rod 69 is extended, the roller follower 73 and the pressing roller 75 approach toward a position displaced from the axis of the core member 23. The outer surface of the roller follower 73 is in contact with the outer surface of the guide plate 39, and the upper part of the outer surface of the pressing roller 75 is in contact with the outer surface of the guide plate 41. Further, when the cylinder rod 69 is extended, the roller follower 73 at a position shifted from the axis of the guide plate 39 rolls on the outer peripheral surface of the guide plate 39 without being locked when the roller follower 73 comes into contact with the guide plate 39. Further, the pressing roller 75 rolls on the outer peripheral surface of the guide plate 41 and moves around the core member 23 in a state where the core member 23 is spaced a predetermined distance. At this time, the end of the fluid pressure cylinder 67 is pulled by the tension spring 77, and the roller follower 73 and the pressing roller 75 are urged by the guide plate 39 and the guide plate 41, respectively.

  Further, the annular forming apparatus 1 is provided with a detecting means 57 such as a photoelectric switch for detecting the presence or absence of the bar-shaped food dough 3 conveyed on the conveyor 5 on the side of the conveyor 5. The annular forming apparatus 1 is provided with a control device 59 (not shown). The control device 59 is composed of a computer, and the sensing means 57 senses the presence or absence of the food dough 3 at a predetermined position of the transport conveyor 5 and also detects a detection signal for sensing the passage of the food dough 3 and the transport conveyor 5. This has a function of calculating the length of the food dough 3 and the transport position of one end portion (tip in the transport direction) 3A located on the downstream side of the food dough 3 based on the transport distance. Further, the control device 59 includes a lifting / lowering operation device 22 that moves the core member 23 up and down, a reciprocating rotation device 48 that rotates the rounding forming portion 9, a reciprocating device using a fluid pressure cylinder 46 that reciprocates the clamping member 47, and a pressure roller. The operation of the moving device 62 that moves 75 is controlled.

  In the above-described configuration, a process of forming the rod-shaped (long shape) food dough 3 in an annular shape will be described with reference to FIGS. As an initial position of the annular forming portion 9, the core member 23 is waiting at a lowered position that protrudes downward from the lower surface of the guide plate 41 by the lifting / lowering operation device 22 and approaches the transport surface of the transport conveyor 5. Further, the clamping member 47 is in a state separated from the core member 23 by the fixing device 44. Further, the clamping member 47 is disposed by the reciprocating rotation device 48 at a position where the cylinder rod 45 is directed in the width direction of the transport conveyor 5 on the stand member 21 side (upper side in FIG. 4) with respect to the core member 23. . The pressing roller 75 stands by at a position away from the core member 23 by the moving device 62 (see FIGS. 4 and 5).

  The rod-shaped food dough 3 is conveyed from the upstream side to the downstream side of the conveyor 5 and moved in the width direction of the conveyor 5 (horizontal direction orthogonal to the conveying direction) by the guide roller 19 of the guide unit 11. The position of the side surface (lower side in FIG. 5) of the food dough 3 is matched with the position of the peripheral surface (upper side in FIG. 5) of the core member 23. When one end portion 3A located on the downstream side of the food dough 3 is detected by the sensing means 57, the transfer position of the food dough 3 in the transfer direction is calculated by the calculation processing function of the control device 59. When the one end portion 3A of the food dough 3 is conveyed between the core member 23 that waits at a position in which the food dough 3 is lowered in advance and the pinching member 47 that waits at a position previously separated from the core member 23, the sandwiching member The cylinder rod 45 of the fluid pressure cylinder 46 that supports 47 is retracted, and the end portion 3A is pressed toward the core member 23 so as to be sandwiched and fixed between the outer peripheral surface of the core member 23 (see FIG. 6). ).

  Next, FIG. 7 shows a case where the rotary actuator 53 of the reciprocating rotation device 48 is operated to rotate the annular forming portion 9 270 degrees counterclockwise. This operation is performed by rotating the food dough 3 together with the core member 23 around the axis of the core member 23 in a state where the one end 3A of the food dough 3 is fixed to the sandwiching member 47. The one end portion 3A and the other end portion 3B come close to each other and are formed into a C shape (see FIG. 7). It should be noted that the rotation angle of the reciprocating rotation device 48 is not limited to 270 degrees. For example, the reciprocating rotation device 48 rotates more greatly to increase the one end 3A and the other end 3B of the food dough 3. Moreover, it can also be made to contact | connect strongly and can be wound in cyclic | annular form, and can be set suitably. Further, the binding amounts (overlapping degree) of the both end portions 3 </ b> A and 3 </ b> B of the food dough 3 change depending on the relationship between the length of the food dough 3 and the surrounding length of the core member 23. Therefore, when the core member 23 is always made with a constant thickness, the length of the food dough 3 is adjusted. When the length of the rod-shaped food dough 3 is constant, the core member 23 is set to the surrounding length. The amount of binding can be adjusted by replacing the parts with different ones.

  Then, by operating the fluid pressure cylinder 46 of the fixing device 44 and extending the cylinder rod 45, the clamping member 47 is separated from the core member 23 and the fixing of the end portion 3A is released. Then, by operating the fluid pressure cylinder 67 of the moving device 62 and extending the cylinder rod 69, the pressing roller 75 approaches the core member 23 and comes into contact with the guide plate 41. At this time, the pressing roller 75 presses a part of the other end 3B of the food dough 3 toward the core member 23 and the one end 3A and overlaps the end 3A (see FIG. 8).

  Further, the extension operation of the cylinder rod 69 is continued, and the pressing roller 61 is guided by the outer peripheral surface of the guide plate 41 and moves around the core member 23, so that the other end extends outside the one end 3A. While overlapping the part 3B, the outer peripheral part of the food dough 3 is gently formed from the other end part 3B to the one end part 3A. Then, both end portions 3A and 3B of the food dough 3 are bound, and the rod-shaped food dough 3 is formed in an annular shape along the outer peripheral surface of the core member 23 (see FIG. 9).

  As described above, when the inner peripheral surface of the annularly shaped food dough 3 is wound around the core member 23, the fluid pressure cylinder 35 of the lifting / lowering operation device 22 is operated to retract the cylinder rod 33. By operating, the core member 23 is lifted away from the transport surface of the transport conveyor 5 and moved upward from the lower surface of the guide plate 41. At this time, the annularly formed food dough 3 is lifted upward as the core member 23 is raised, but is pressed against the lower surface of the guide plate 41, so that the core member 43 can be removed from the food dough 3. . Thus, the guide plate 41 has a function as a pulling member that scrapes off the food dough 3 formed in an annular shape from the core member 23. Further, the annular molding portion 9 returns to the initial position and waits until the next food dough 3 is conveyed.

  The annular food dough 3 placed on the transport surface of the transport conveyor 5 is transported downstream (left side in FIG. 1) by endless rotation of the conveyor belt. And it accommodates in the type | mold top plate provided with the cyclic | annular recessed part, and performs appropriate heat processing, such as a proof and baking, and shape | molds in a final product. The final product is a baked donut whose inner material is covered with a cake donut dough. As another example, bread products such as confectionery bread and bagels can be molded.

  As will be understood from the above description, when the long-shaped food dough 3 is formed into an annular shape, one end 3A of the food dough 3 is fixed to the core member 23, and the core member 23 is set within a required angular range. , The food dough 3 is wrapped around the core member 23, and can be formed into a C shape or an annular shape so that one end 3A and the other end 3B of the food dough 3 approach or contact each other. Since both ends 3A and 3B of the food dough 3 can be connected to each other by pressing the end portion 3B of the food dough 3 with a pressing roller 75 as a pressing member, the annular formation of the rod-shaped food dough 3 is performed. It can be done efficiently.

By the way, the present invention is not limited to the above-described embodiments, and can be implemented in other modes by making appropriate changes. For example, the pressing member provided in the pressing device 61 has been described as the pressing roller 75 that rolls around the core member 23, but as shown in FIG. A pressing device 79 including a plate 81 may be used. A reciprocating device 83 for reciprocating the pressing plate 81 is provided on the side of the conveyor 5 located on the stand member 21 side. The reciprocating device 83 is provided with a fluid pressure cylinder 85 in a state where the operating direction of the cylinder rod 87 is directed in the width direction W of the conveyor 5, and the pressing plate 81 is attached to the tip of the cylinder rod 87. ing.

  The pressing surface 81A facing the core member 23 of the pressing plate 81 is disposed in a direction inclined with respect to the transport direction R and the width direction W orthogonal thereto. By bringing the pressing surface 81A closer to the core member 23, the other end portion 3B of the food dough 23 wound around the core member 23 is pressed toward the core member 23 side and the one end portion 3A side. Then, the other end portion 3B is overlapped on the outside of the one end portion 3A to bind both end portions 3A and 3B, and the outer periphery of the food dough 3 is gently formed. The shape of the pressing surface 81A is not limited to a flat surface, and may be a concave curved surface corresponding to the outer peripheral surface of the core member 23. The outer peripheral portion of the annularly formed food dough 3 can be formed into a curved surface. It is.

  In FIG. 4, the cylinder rod 69 extends and the pressing roller 75 located at a position deviated from the center of the core member 23 approaches the core member 23. The amount of misalignment of the core of the core member 23 can be arbitrarily set in order to adjust the binding amount of the food dough 3 as a design matter. In the present embodiment, the cylinder rod 69 extends along the width direction W of the conveyor 5 and contacts the core member 23. However, in order to make the outer peripheral surface of the pressure roller 75 guide plate 1 easy to roll. For example, the input direction of the cylinder rod 69 may be arranged obliquely with respect to the width direction W.

  Further, as a configuration of a fixing device for fixing one end side 3A of the rod-shaped food dough 3 to the outer peripheral surface of the core member 23, the cylinder rod 33 is a hollow tube member, and the tube member has a negative load. It is also possible to generate a pressure to generate a suction action on a part or all of the outer peripheral surface of the core member 23, and to fix one end side 3A of the food dough 3 by this suction action. An aspect provided with a plurality of slits or a sintered alloy can be used for the suction portion.

  When the food dough 3 is wound around the core member 23 and the core member 23 is pulled out of the food dough 3, if compressed air is supplied to the tubular cylinder rod 33 core member 23, air is radially emitted from the outer peripheral surface of the core member 23. , And an air layer (air film) can be formed between the outer peripheral surface of the core member 23 and the inner peripheral surface of the food dough 3 in a wound state. In other words, by providing the air jetting means for forming the air layer, the adhesion (adhesion) of the food dough 3 to the core member 23 can be suppressed, and the extraction can be performed efficiently.

  By the way, the cross-sectional shape of the core member 23 is not limited to a circular shape, and may be a regular polygonal shape or a configuration in which a plane (common name: D surface) is formed at a plurality of locations on a circular outer peripheral surface. Thus, by setting it as the structure provided with the regular polygon shape and the flat part in the outer peripheral surface, the hook at the time of the winding action of the food dough 3 around the core member 23 is good, and the winding of the food dough 3 can be performed efficiently. is there. In addition, each said member touching the food dough 3 is highly non-adhesive, for example, adopts resin materials, such as high molecular weight polyethylene, polyacetal, a fluororesin, and well-known surface treatment, and is used to each member of the food dough 3 Adhesion can be suppressed, and stable molding becomes possible.
