  The guide plate 47 prevents the tofu dough 11 in the water 13 from detaching from the inversion frame 41 when the tofu dough 11 is reversed. As will be described later, the return mechanism 46 receives the tofu dough 11 to the carry-out device 60 and reverses the reversing frame 41 that has become empty from below the sprocket 43 to accommodate the tofu dough 11. Return to.

  Below the conveyor 40, a conveyor-type transport device 51 having an endless conveyor 53 that is wound around a pair of sprockets 52 a and 52 b and circulates in a clockwise direction is arranged in parallel with the conveyor 40. The endless conveyor 53 travels at substantially the same speed as the endless conveyor 44, and supports or sandwiches the tofu dough 11 between the endless conveyor 44 and the endless conveyor 53. The endless conveyor 53 is not particularly limited as long as it is a material that does not easily damage the tofu dough, such as a smooth resin belt for food, a metal belt such as stainless steel, and a bar conveyor constituted by a large number of round bars. The lower endless conveyor 53 may be a simple and inexpensive structure by using a smooth, low friction plate or the like.

  The carry-out device 60 includes a carry-out conveyor 61, a second cutter device 65, and a third cutter device 71. The carry-out conveyor 61 is disposed on the downstream side of the conveyor 40, and includes an endless conveyor 63 that wraps around a pair of sprockets 62 a and 62 b and circulates in a clockwise direction. Transport. The carry-out conveyor 61 may be a transfer device including a smooth plate and a push-feed mechanism.

  The second cutter device 65 is driven by a cylinder 66a up and down, a second cutter plate 68 driven up and down by a cylinder 66b, a cylinder 66c driven up and down, and a cylinder 66d driven downstream. A feeding plate 69.

  The second cutter device 65 lowers the stopper plate 67 with the cylinder 66a and stops the conveyance of the tofu dough 11 conveyed by the carry-out conveyor 61, then lowers the feeding plate 69 with the cylinder 66c, and further with the cylinder 66d. Driving in the downstream direction, the front and rear of the tofu dough 11 are sandwiched between the stopper plate 67 and the feeding plate 69. Thereby, the tofu dough 11 is positioned in the front-back direction. Next, the second cutter plate 68 is lowered by the cylinder 66b, and the second cut is made on the tofu dough 11, and is divided into M equal parts (in the embodiment shown in the figure, two equal parts), and the length corresponding to one in the row direction. The tofu dough 11B is cut.

  The third cutter device 71 includes a third cutter plate 73 that is driven up and down by a cylinder 72. The third cutter plate 73 has a plurality of cutters arranged in a direction (row direction) perpendicular to the paper surface, for example, nine cutters (11 if the fabric ears at both ends are removed). A third cut is made on the tofu dough 11B that has been cut to a length of minutes, and the tofu dough 11C has a width equal to one in the row direction by dividing it into N equal parts (10 equal parts in the embodiment shown in the figure). The product size to be packaged. The tofu dough 11 becomes M × N (for example, 20) final tofu products 11C by the second and third cuts. Then, it is packed in the packaging pack 75 on the downstream side of the third cutter device 71.

  Next, the operation of this embodiment will be described. The sheet-like tofu dough 11A conveyed onto the mounting table 22 by the conveyor 21 performs the first cutting by lowering the first cutter plate 25, for example, the length of two final tofu products 11C ( It is cut into a substantially rectangular parallelepiped-shaped tofu dough 11 having a width in the conveying direction and a row direction) and a width corresponding to 10 (a direction perpendicular to the conveying direction and a length in the row direction). The 1st cutter plate 25 which performed the 1st cutting | disconnection moves further to the right direction, and pushes out the tofu dough 11 from the mounting base 22 to the right direction in the figure.

  The first cutter plate 25 that has pushed out the tofu dough 11 from the mounting table 22 is driven and lifted by the cylinder device 26 and the drive device 27, and then moves upstream to return to the original position, and the next cutting is performed. Make preparations.

  The tofu dough 11 pushed rightward by the first cutter plate 25 is accommodated in a reversal frame 41 that travels from the sprocket 43 toward the sprocket 42. Since the side plate 41b is disposed behind the endless conveyor 44 in the running direction, the tofu dough 11 is placed on the bottom plate 41a of the reversal frame 41, and the front cut surface 11c of the tofu dough 11 abuts on the side plate 41b. Is contained. Since the first cutting of the sheet-like tofu dough 11A, the extrusion of the tofu dough 11 and the accommodation in the reversal frame 41 are performed in the water 13 or near the surface of the water 13, the soft tofu dough 11 is damaged. It can accommodate in the inversion frame 41, without receiving.

  The tofu dough 11 accommodated in the reversal frame 41 is rotated by approximately 180 ° so as to wrap around from the upper side of the sprocket 42 by the reversing mechanism 45 to be turned upside down. Since this reversal is performed in the water 13, the tofu dough 11 may be separated from the reversal frame 41 due to buoyancy or water flow, but the tofu dough 11 is arranged along the outer periphery of the reversal trajectory of the reversal frame 41. Since it is guided by the guide plate 47 having an arcuate cross section, it is not separated from the upper end of the reversal frame 41, particularly the side plate 41b, and therefore the tofu dough 11 is reliably reversed without being damaged. At the time of reversal, it is preferable that the conveyor 40 is not transported so fast that a strong centrifugal force is applied, but rather the radius of the sprocket 42 is increased and the conveyor 40 is transported slowly.

  The tofu dough 11 that is turned upside down by the reversing mechanism 45 is enclosed between the endless conveyor 53 of the conveyor-type transport device 51 that travels at substantially the same speed while being accommodated in the reversing frame 41 and the reversing frame 41 of the conveyor 40. In this way, the water 13 is transported to the land from the water 13 and transferred to the transport conveyor 61 of the carry-out device 60.

  The reversal frame 41 that has been emptied after the tofu dough 11 is transferred to the conveyor 61 is reversed by the return mechanism 46 so as to wrap around from the lower side of the sprocket 43 and is conveyed in the direction of the mounting table 22 to transfer the next tofu dough 11. Accommodate.

  The tofu dough 11 conveyed by the carry-out conveyor 61 is positioned by sandwiching the front and back of the tofu dough 11 between the stopper plate 67 and the feeding plate 69 and then divided into M equal parts by the second cutting by the second cutter plate 68 ( In the embodiment shown in the figure, it is divided into two equal parts) to form a tofu dough 11B having a length of one in the row direction. Next, a plurality of cutters are divided into N equal parts (10 equal parts in the embodiment shown in the figure) by the third cutting by the third cutter plate 73 arranged in parallel in the width direction (row direction) of the tofu dough 11B. The tofu dough 11C is one width wide in the row direction. Thereby, the tofu dough 11 is cut into the size of the final tofu product 11 </ b> C and packed in the packaging pack 75. When the sheet-like tofu dough 11A conveyed by the conveyer 21 becomes the tofu dough 11 (M = 1, N ≧ 2) tofu dough 11 (horizontally long rectangular parallelepiped) in one row, the second cutter device In this form, 65 is omitted. In the present application, the form of cutting from the sheet-like tofu dough to the final tofu product 11C in multiple stages, and the form of packing in the next process are cut forms that pass through the tofu dough 11 (horizontally long rectangular parallelepiped). There is no particular limitation. Although the reversing mechanism of the present application can be applied to the final tofu product 11C, it is possible to reduce the damage to the tofu dough by reversing it as a large lump as in the present application with a horizontally long belt-like substantially rectangular parallelepiped. preferable.

  As described above, according to the tofu dough reversing device 10 of the present embodiment, the plurality of reversing frames 41 that can each accommodate the tofu dough 11 having a size including the final tofu product 11C in a plurality of rows and a plurality of columns. A conveyor 40 having an endless conveyor 44 that is disposed at predetermined intervals and circulates, a loading device 20 that is disposed on the upstream side of the conveyor 40, conveys the tofu dough 11 and stores it in the reversal frame 41, and the conveyor 40, and a carry-out device 60 for feeding the tofu dough 11 taken out from the reversal frame 41. The conveyor 40 is disposed at the upstream end portion, and is disposed at the downstream end portion and the reversing mechanism 45 for reversing the vertical direction of the reversing frame 41 that accommodates the tofu fabric 11, and the tofu dough 11 is unloaded and becomes empty. And a return mechanism 46 that further reverses the inverted frame 41 that is turned upside down and returns the tofu dough 11 to a state in which the tofu dough 11 can be accommodated, so that the final tofu product 11C has a size that includes a plurality of rows or a plurality of rows. The tofu dough 11 can be inverted. Therefore, the tofu dough 11 corresponding to a large amount of the final tofu product 11C can be inverted at a time and slowed down without damaging the tofu dough 11 as compared with the case where it is inverted after cutting into one final tofu product. Even in operation, the processing capability can be increased. As a result, the final tofu product can be efficiently produced and the commercial value can be improved. If the tofu dough is hard, the conveyor type transport device 51 may be a smooth and low friction plate and a simple and inexpensive form.

  Further, since the reversing mechanism 45 includes the guide plate 47 having a circular arc cross section disposed along the outer periphery of the reversing locus of the reversing frame 41, the tofu dough 11 is guided by the guide plate 47 during reversal, and the tofu dough is guided. 11 is not separated from the reversal frame 41, and thus can be reliably reversed without damaging the tofu dough 11.

  Moreover, since the storage position which accommodates the tofu dough 11 in the inversion frame 41 from the carrying-in apparatus 20 is arrange | positioned in the water 13, it does not damage the tofu dough 11, and a quick operation | movement is unnecessary and it is high also in the slow operation | movement. Inversion processing can be performed with the processing capability.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a schematic configuration diagram of a tofu dough reversing device according to a second embodiment of the present invention. The tofu dough reversing device of the present embodiment includes a pressing mechanism that accommodates the tofu dough in a reversing frame. The other parts are the same as those of the tofu dough reversing device according to the first embodiment of the present invention. Therefore, the same parts are denoted by the same or corresponding reference numerals, and the description thereof will be simplified or omitted.

In the tofu dough reversing device 10 of this embodiment, a pressing mechanism 30 that presses the tofu dough 11 from above is disposed at a delivery position where the tofu dough 11 is accommodated from the mounting table 22 to the reversing frame 41. The pressing mechanism 30 is driven by a driving device (not shown) so as to rotate up and down, left and right, or circulate, and includes four pressing portions 31 that rotate or rotate counterclockwise along a substantially square shape. Have. The pressing portion 31 causes the lower surface 31 a to press the tofu dough 11 pushed out from the mounting table 22 from the upper side to the lower side so as to be accommodated in the reversal frame 41. In particular, since the tofu dough 11 in the water is easily distorted due to the flow of water or the like, the pressing portion 31 has an effect of further speeding settling due to its own weight and storing it in the reversing frame 41 while pressing it so as not to be distorted. There is. The pressing portion 31 is sufficiently heavy to push down the tofu dough in the water, and is preferably connected to the drive device at a position above the center of gravity so as to hang in a gondola manner. In order not to be distorted by the water flow, a configuration in which a guide that supports the tofu dough 11 from two to four directions is provided at the lower end of the pressing portion 31 and a configuration in which the lower section of the pressing portion 31 has a downward U-shape is preferable. Moreover, the form provided with opening parts, such as a water drain hole, in the side surface and upper surface of the press part 31 is preferable. The form of these pressing parts 31 will not be specifically limited if it is a form which fulfill | performs the same function. The guide is opened downward so as not to damage the tofu dough 11 so as not to interfere with the reversal frame 41 and its side plate 41b.
In addition, there is an effect that the operating time loss due to the reciprocating operation can be reduced by the pressing portion moving mechanism that rotates or rotates around the pressing portion 31, and the disturbance of the water flow during underwater storage can be reduced.

  The conveyor 40 is guided by an idler 48 disposed on the downstream side of the sprocket 42, and the upstream end facing the mounting table 22 travels in the horizontal direction. The reversing mechanism 45 is spaced downward from the mounting table 22, and the first guide plate 32 is provided in the vertical direction between the downstream end of the mounting table 22 and the upper end of the guide plate 47 having an arcuate cross section. It has been. Further, on the downstream side of the mounting table 22, a second guide plate 33 is provided in the vertical direction at a distance substantially the same as the length of the tofu dough 11. The first guide plate 32 and the second guide plate 33 guide the tofu dough 11 pushed into the water 13 from the mounting table 22 and perform positioning in the front-rear direction. The first guide plate 32 and the second guide plate 33 may be made of flexible rubber or resin so as to contact and interfere with the pressing portion 31 or the side plate 41b of the reversal frame 41.

  The operation of this embodiment will be described. The first cutter plate 25 pushes the tofu dough 11 having a predetermined size by first cutting the sheet-like tofu dough 11 </ b> A from the mounting table 22 in the right direction in the figure. At this time, the front-side cut surface 11c of the tofu dough 11 comes into contact with the second guide plate 33, so that the position of the tofu dough 11 in the front-rear direction is positioned. In the step of extruding the tofu dough 11 from the mounting table 22 into the water 13, when the tofu dough 11 is in a semi-submersible state in the vicinity of the water surface of the water 13, particularly a part of the tofu dough 11 is in the air, the second The guide plate 33 may be omitted, and the guide plate 33 may be positioned in contact with the side plate 41b of the reversal frame 41.

  Here, when the pressing mechanism 30 is operated and the four pressing portions 31 are rotated counterclockwise, the pressing portion 31 located above the tofu dough 11 pushed into the water 13 by the first cutter plate 25. Descends and pushes down the tofu dough 11 and sandwiches it between the lower surface 31 a of the pressing portion 31 and the bottom plate 41 a of the reversal frame 41. Thereby, the tofu dough 11 whose posture is unstable due to buoyancy in the water 13 is reliably and quickly accommodated in the reversal frame 41. When the plurality of pressing portions 31 are provided and rotated, the mechanical operation is smoother than the reciprocating operation, the water flow is less disturbed, the posture of the tofu dough in the water is stabilized, and the return time is saved and the processing capacity is reduced.
