[Description of endless belt path]

  FIG. 2 is a right side view of the rolling device 1 as viewed from the direction of the right side plate 3 of the casing 9 (the direction of arrow A in FIG. 1A). FIG. 2 shows a state in which the right side plate 3 is removed so that the internal structure of the rolling device 1 can be understood.

  As shown in FIG. 2, the endless belt 36 is stretched around a plurality of guide rollers 42, 43, 44.

  Among these, the guide roller 42 is disposed in the vicinity of the work table 4. The puff pastry 100 is put on the endless belt from this position. The worktable 4 is provided substantially horizontally, and the path of the endless belt 36 is set in the vicinity of the worktable 4 so that the extended surface of the worktable 4 and the path of the endless belt 36 are substantially in the same plane. .

  The endless belt 36 extending in a substantially horizontal direction passes between a pair of rolling rollers 52 (a rolling roller 52a and a thickness adjusting roller 52b) sandwiching the endless belt 36.

  The endless belt 36 that has passed through the pair of rolling rollers 52 is detached upward from the rolling roller 52a. At this time, the path of the endless belt 36 is set so that the direction in which the endless belt 36 contacts the rolling roller 52a and the direction in which the endless belt 36 separates from the rolling roller 52a (angle θ in FIG. 2) form an acute angle. .

  The endless belt 36 separated upward from the rolling roller 52 a is stretched around the guide roller 43. The path of the endless belt 36 is set downward by the guide roller 43.

  The endless belt 36 that has been stretched downward in this manner is then stretched across the guide roller 44. The guide roller 44 is connected to a tension arm 45, and the tension of the endless belt 36 is adjusted by the elastic force of a tension spring 46 that is locked to the tension arm 45.

The endless belt stretched around the guide roller 44 returns to the position of the guide roller 42 again. In this way, the path of the endless belt 36 is set.
[Description of drive force transmission mechanism]

  The endless belt 36 moves with a driving force applied by the rotational force generated by the motor 20 shown in FIG. First, the rotational force of the motor 20 is output as the rotational force of the sprocket 22 and is transmitted by the chain 28 a constituting the driving force transmission unit 28 spanned over the sprocket 22.

  The chain 28 a is spanned from the sprocket 22 in the order of the tensioner 24, the main drive sprocket 26, the rolling roller 52 a, the drive shaft sprocket 30, and the idle sprocket 32. The chain 28a moves in the direction of the arrow D0. The main drive sprocket 26 is engaged with the thickness adjusting roller 52b via a gear sprocket (not shown in FIG. 2).

  For this reason, as the chain 28a moves in the direction of the arrow D0, the rolling roller 52a on which the chain is bridged rotates. Then, the endless belt 36 in contact with the rolling roller 52a moves in the direction of the arrow D1. Further, the thickness adjusting roller 52b rotates at the same peripheral speed as the rolling roller 52a in the rotation direction opposite to the rolling roller 52a.

Here, a driving belt 28 b constituting the driving force transmission unit 28 is stretched over the driving shaft sprocket 30. The drive belt 28b is stretched around take-up rollers 72 and 74 (food dough delivery section), and the take-up rollers 72 and 74 rotate as the drive shaft sprocket 30 rotates.
[Description of internal structure of rolling roller]

  As shown in FIG. 4, a rotary joint 56 is connected to one shaft end of the rolling roller 52a.

  The rotary joint 56 is used when supplying or discharging a pressurized fluid from a fixed pipe to a rotary part without leaking, and is also called a rotary joint.

  The rotary joint 56 shown in the present embodiment has both a refrigerant inlet 58 through which refrigerant flows from the outside and a refrigerant outlet 59 through which refrigerant flows out. And while sending a refrigerant | coolant inside the rotating rolling roller 52a, the refrigerant | coolant discharged from the rotating rolling roller 52a is discharged | emitted outside.

  Inside the rolling roller 52a, a refrigerant channel 55 is formed by a refrigerant pipe 53 and a roller internal space 54. The rotary joint 56 having such a structure is called a double inner pipe fixed type, and supplies water, steam, or oil into a rotating roller, drum, cylinder, or the like from the same side as the supply side. It is used in the scene where it is discharged.

  The refrigerant that has flowed from the refrigerant inlet 58 flows into the roller internal space 54 through the refrigerant pipe 53. Since the refrigerant flows into the refrigerant pipe 53 one after another through the refrigerant inflow port 58, the refrigerant flowing into the roller internal space 54 moves toward the refrigerant discharge port 57 due to the pressure of the refrigerant. Due to the movement of the refrigerant, the surface of the rolling roller 52a is evenly cooled.

  The refrigerant discharged from the refrigerant discharge port 57 passes through the rotary joint 56 again and flows out from the refrigerant outlet 59 to the outside.

  That is, the refrigerant circulates inside the rolling roller 52a along the arrows I1, I2, I3, and I4 shown in FIG.

A heat exchanging unit (not shown in FIG. 4) is provided outside the rolling roller 52a, and the warmed refrigerant that has flowed out of the rolling roller 52a is cooled by the heat exchanging unit, and again enters the refrigerant inlet 58. Supplied.
[Description of structure of roller interval adjusting mechanism]

  FIG. 3 is a left side view of the rolling device 1 as viewed from the direction of the left side plate 2 of the housing 9 (the direction of arrow B in FIG. 1A). In addition, FIG. 3 has shown the state which removed the left side plate 2 so that the internal structure of the rolling device 1 could be understood.

  In FIG. 3, a roller shaft 10i, which is a rotation shaft of the thickness adjusting roller 52b, is engaged with a roller driving plate 10g.

  The roller driving plate 10g is locked to a frame (not shown) of the rolling device 1 so as to rotate clockwise or counterclockwise on the paper surface of FIG. 3 around the position of the roller support pin 10h.

  One end of a rod end bar 10e is rotatably locked by a roller drive pin 10f on the upper portion of the roller drive plate 10g.

  The other end of the rod end bar 10e is rotatably locked to the lever fitting 10a by a lever fitting pin 10d.

  A lower portion of the lever fitting 10a is rotatably locked to a frame (not shown) of the rolling device 1 by a cam shaft 10b. A thickness adjusting handle 7 is connected to the upper portion of the lever fitting 10a. It is installed.

  When the thickness adjusting handle 7 is rotated clockwise or counterclockwise on the paper surface of FIG. 3 with the cam shaft 10b as a fulcrum, the position of the lever metal fitting pin 10d is moved, and the rod end bar 10e is interlocked with it. The position of the roller drive pin 10f moves.

  Then, since the roller drive plate 10g that is rotatably engaged with the rod end bar 10e by the roller drive pin 10f rotates around the roller support pin 10h, the roller that is rotatably engaged with the roller drive plate 10g. The position of the shaft 10i moves, and the position of the thickness adjustment roller 52b moves.

  Thus, by moving the thickness adjusting handle 7, the distance between the rolling roller 52a and the thickness adjusting roller 52b can be adjusted.

  In the rolling apparatus 1, the same mechanism as described above is also provided on the right side plate 3 (see FIG. 1A) side of the rolling apparatus 1 in order to reliably adjust the distance between the rolling roller 52 a and the thickness adjusting roller 52 b. Is incorporated.

  That is, the cam shaft 10b penetrates from the left side surface side to the right side surface side of the rolling device, and the movement amount of the thickness adjusting handle 7 becomes the rotation angle of the cam shaft 10b and moves to the right side surface side of the rolling device 1. Is also communicated.

  The rotation of the cam shaft 10b rotates the lever fitting 10c in FIG. 2, and moves the position of the rod end bar 10k that is rotatably locked to the lever fitting 10c by the lever fitting pin 10j.

  Further, the position of the roller drive plate 10m that is rotatably locked to the rod end bar 10k is moved by the roller drive pin 101.

  Since this roller drive plate 10m is rotatably locked around the roller support pin 10n, the position of the roller shaft 10i locked to the roller drive plate 10m, that is, the position of the thickness adjusting roller 52b is moved. Let

  Thus, the movement amount of the thickness adjusting handle 7 is given to both ends of the thickness adjusting roller 52b. Thereby, the space | interval of the rolling roller 52a and the thickness adjustment roller 52b can be adjusted stably and reliably.

The lever fitting 10a (10c), the cam shaft 10b, the lever fitting pin 10d (10j), the rod end bar 10e (10k), the roller driving pin 10f (10l), the roller driving plate 10g (10m), and the roller supporting pin 10h. (10n), the roller shaft 10i constitutes the roller interval adjusting unit 10.
[Description of structure of thickness adjustment handle]

  As shown in FIGS. 5 and 6, the thickness adjusting handle 7 includes a lever fitting pipe 65, a handle 64, a coil spring 66, a first holding lever 68, and a second holding lever 69.

  The lever fitting pipe 65 is connected to the upper side of the lever fitting 10a and has a hollow cylindrical shape.

  The handle 64 is a rod-like member included in the lever fitting pipe 65 and slides inside the lever fitting pipe 65. An elastic member such as a coil spring 66 is provided between the end of the handle 64 between the end inserted into the lever fitting pipe 65 and the inner end of the lever fitting pipe 65. Due to the urging force of the coil spring 66, a force in a direction protruding from the lever fitting pipe 65 is received.

  The first holding lever 68 is fastened to the side surface of the lever fitting pipe 65 at a right angle.

  The second holding lever 69 passes through a slit hole 70 provided on the side surface of the lever fitting pipe 65 and is fastened to the side surface of the handle 64 at a right angle.

  The position of the handle 64 can be moved within the lever fitting pipe 65 within a range in which the second holding lever 69 moves in the slit hole 70.

  As the handle 64 moves, the amount of protrusion of the claw 63 provided at one end of the handle 64 from the lever fitting pipe 65 changes.

  The claw portion 63 normally protrudes from the lever metal fitting pipe 65 by the urging force of the coil spring 66. The protruding claw portion 63 is engaged with a latch claw 61 provided on a latch plate 62 fixed to a frame (not shown) of the rolling device 1 so that the position of the thickness adjusting handle 7 is maintained. ing.

  When the operator of the thickness adjusting handle 7 grips the first holding lever 68 and the second holding lever 69 and applies a force, the handle 64 fastened to the second holding lever 69 causes the biasing force of the coil spring 66 to be applied. Against this, the claw portion 63 moves in the direction of retraction from the tip of the lever fitting pipe 65 in order to move upward in the drawing of FIG. 5 or FIG.

  Then, the engagement between the claw portion 63 and the latch claw 61 is released, and the lever fitting 10a connected to the thickness adjusting handle 7 can be rotated around the cam shaft 10b.

  In this way, the operator moves the thickness adjustment handle 7 back and forth to adjust the distance between the rolling roller 52a and the thickness adjustment roller 52b.

  In FIG. 5, when the thickness adjustment handle 7 is moved counterclockwise (forward), the distance between the rolling roller 52a and the thickness adjustment roller 52b is reduced. On the other hand, in FIG. 5, when the thickness adjustment handle 7 is moved clockwise (rearward), the distance between the rolling roller 52a and the thickness adjustment roller 52b is increased.

When the holding of the second holding lever 69 is loosened when the rolling roller 52a and the thickness adjusting roller 52b are at a predetermined interval, the claw portion 63 protrudes from the tip of the lever fitting pipe 65 by the urging force of the coil spring 66. Move in the direction. Then, the position of the thickness adjustment handle 7 is held by engaging the claw portion 63 and the latch claw 61, and thus the set interval between the rolling roller 52a and the thickness adjustment roller 52b is held. The
[Description of Operation of Example 1]

  Next, the effect | action of the rolling apparatus 1 is demonstrated using FIGS. 7-12.

  FIG. 7 is a cross-sectional view of the rolling device 1 cut along the cutting line CC in FIG. 1B, and shows a conveyance path of the pie dough 100 (food dough) introduced from the work table 4. . 8 to 12 show the flow of the rolling operation of the pie dough 100 using the same cross-sectional view as FIG.

(Description of pie dough charging operation (first operation))
FIG. 8 shows the state of the first operation of putting the pie dough 100 a on the work table 4 into the endless belt 36. The operator of the rolling apparatus 1 operates the foot switch 6 (see FIG. 1) to start the movement of the endless belt 36.

  At this time, as described above, the rolling roller 52a is rotated in the direction of the arrow A1 by receiving the rotational driving force from the chain 28a (FIG. 2). And since the endless belt 36 is spanned over the rolling roller 52a, it moves to the direction of arrow D1 with rotation of the rolling roller 52a.

  The guide roller 42 around which the endless belt 36 is stretched rotates in the direction of arrow A2, the guide roller 43 rotates in the direction of arrow A3, and the guide roller 44 rotates in the direction of arrow A4.

  Thickness adjusting roller 52b receives a rotational driving force via chain 28a (FIG. 2) and main drive sprocket 26 (FIG. 2), and rotates in the direction of arrow A5 at the same peripheral speed as rolling roller 52a.

  As described above, each of the winding rollers 72 and 74 is rotated in the direction of the arrow A6 by receiving a rotational driving force from the driving belt 28b (FIG. 2).

  Then, the puff pastry 100b put on the endless belt 36 is conveyed in the direction of the arrow D1 as the endless belt 36 moves.

(Description of pie dough rolling operation (second operation))
FIG. 9 shows a state of the second operation in which the pie dough 100c is rolled by the rolling device 1 so as to pass through the state of the pie dough 100d to the state of the pie dough 100e.

  The puff pastry 100c placed and conveyed on the endless belt 36 is sandwiched between the rolling roller 52a and the thickness adjusting roller 52b and has a thickness defined by the interval between the rolling roller 52a and the thickness adjusting roller 52b. And rolled into a puff pastry 100d state.

  At this time, when the pie dough 100d is sandwiched between the rolling roller 52a and the endless belt 36, the pie dough 100d receives forces in the direction of being crushed in the thickness direction from the rolling roller 52a and the thickness adjusting roller 52b, respectively. Rolled.

  Thereafter, the pie dough 100d moves upward as the rolling roller 52a rotates. Here, the endless belt 36 is spanned so that an angle θ formed by the contact direction with the rolling roller 52a and the detaching direction from the rolling roller 52a forms an acute angle, and constitutes the food dough detaching portion 8. Accordingly, the pie dough 100d is separated from the rolling roller 52a, and is reversed and separated from the endless belt 36 by the action of gravity.

  When the pie dough 100d is conveyed while attached to the endless belt 36, the pie dough 100 is peeled off by contacting the scraper 60 provided at a position facing the guide roller 43, It reverses from the endless belt 36 and leaves.

  Thereafter, the pie dough 100d that is reversed from the endless belt 36 and is separated is conveyed in the direction of the arrow D2 by the rotation of the rolling roller 52a, and is passed over the transfer plate 50 that guides the pie dough 100 in the direction of the work table 4. , Moving from left to right in FIG.

  Then, the pie dough 100d passes over the take-up rollers 72 and 74 (food dough delivery section) rotating in the direction of the arrow A6, and is sent out in the direction of the work table 4 as pie dough 100e.

  The rotation speed (circumferential speed) of the take-up rollers 72 and 74 (food dough delivery section) is set so as to move the pie dough 100e at a higher speed than the speed at which the pie dough 100e passes through the rolling roller 52a. . Therefore, the puff pastry 100e that has passed through the rolling roller 52a is fed in the direction of the work table 4 without being loosened at the positions of the winding rollers 72 and 74.

  The operator of the rolling device 1 guides the tip of the puff pastry 100e that has been fed upside down on the work table 4 with a hand. Then, dust is sprinkled on the surface of the puff pastry 100e spread on the work table 4. This dusting is sprinkled to prevent the pie dough 100e from adhering to the endless belt 36 or the rolling roller 52a. For example, wheat flour or starch powder is used.

  Then, the pie dough 100e is again put into the endless belt 36 from the work table 4 while being turned upside down.

  Thereafter, the second operation is repeated until the puff pastry 100e has a desired thickness while gradually adjusting the distance between the rolling roller 52a and the thickness adjusting roller 52b.

(Description of pie dough rolling operation (third operation))
When the second operation is repeated, the thickness of the pie dough 100e gradually decreases, and eventually the thickness of the pie dough 100e falls below the first predetermined value. At this time, the pie dough 100e fed to the work table 4 becomes thin and increases in area, so that the dough is easily torn and the work to put into the endless belt 36 becomes difficult. Moreover, since the area of the pie dough 100e increases, it cannot fit on the work table 4.

  When this happens, the operator of the rolling apparatus 1 performs the third operation shown in FIG.

  That is, the movement of the endless belt 36 is stopped by operating the foot switch 6 (see FIG. 1). The state of the puff pastry 100e at this time is referred to as a first rolling state. The operator of the rolling device 1 determines that the first rolling state has been reached when the thickness of the pie dough 100 has reached an appropriate thickness for winding onto the winding rod 80 (82).
