The present invention relates to a hoisting device for hoisting, a hoisting fabric shaping device for hoisting a stretched fabric piece while correcting the shape, and a hoisting fabric shaping method.

Conventionally, when manufacturing a croissant, for example, a strip-shaped food dough (laminated dough) conveyed in the longitudinal direction by a belt conveyor as a conveying means is cut into isosceles triangles by a cutting device, and the dough cut into this triangle shape The directionality of the dough piece is made constant so that the bottom side of the piece is on the downstream side. Then, the triangular dough piece is rolled up from the bottom side to the triangular top side by a winding device to form a straight croissant having a thick central portion and narrow both end portions.
However, when the center line of the triangular dough piece is tilted and wound up without being coincident with the conveying direction of the belt conveyor, or when the formed dough piece is bent and does not become an isosceles triangle shape, the top part is There was a problem that the croissant wound up was shifted from the center position toward the end portion, and the shape did not become a symmetrical spindle shape.

There is an apparatus in which a second belt conveyor is provided, a pressure roller is provided above the downstream end of the first belt conveyor and upstream of the upper roller. Furthermore, the upper roller and the pressing roller are provided so as to be movable up and down integrally. The peripheral speed of the pressing roller is substantially the same as the transport speed of the first belt conveyor, and the peripheral speed of the upper and lower extension rollers and the transport speed of the second belt conveyor are set faster than the transport speed of the first belt conveyor. ing.

In addition, a sensor that detects a piece of fabric to be conveyed is provided above the first belt conveyor and upstream of the pressing roller. When the pressing roller and the upper roller are in a state of waiting for the dough to be conveyed in the raised state, the conveyance position of the dough piece is calculated based on the detection signal from the sensor, and the bottom of the triangular dough piece is calculated. After passing through the center position of the upper and lower extension rollers, the pressing roller and the upper roller are lowered to the set height position and press the dough piece.
Then, the dough piece is pulled in the transport direction, and is extended to the top side (see Patent Document 2).

  The dough piece extending device described in Patent Document 1 is said that when the dough piece is extended by the extending roller, the dough piece does not extend evenly due to the air mass that exists unevenly in the dough, and the top side is bent. A technique for solving the problem is disclosed. In other words, the conventional fabric piece extending device prevents the fabric piece from being bent when the fabric piece is extended. When the fabric piece supplied in a bent state is extended, the bending is not corrected. It extends for a long time in the direction of conveyance in a bent state. Therefore, there is a problem that the winding position of the top portion of the wound croissant is shifted from the center position to the end portion side, and the spindle shape is not symmetrical.

In addition, when the center line of the triangular dough piece is inclined and conveyed without matching the conveying direction of the belt conveyor, one corner of the bottom of the dough piece is pressed first against the other corner. There is a problem that the inclination of the dough piece is further promoted because it comes into contact with the roller. In order to solve this problem, the fabric piece extending device described in Patent Document 2 waits the pressing roller and the upper roller upward until the bottom of the fabric piece passes through the centers of the upper and lower extending rollers. Thereby, it is possible to suppress the inclination of the triangular fabric piece, but the inclination cannot be corrected.
Further, even when the formed dough piece is supplied in a bent state without becoming an isosceles triangle shape, the dough piece cannot be corrected to an approximately isosceles triangle shape.
Therefore, there is a problem that the shape of the wound croissant does not become a symmetrical spindle shape.

The dough piece extending device 1 includes a first carrying device 5 for carrying the dough piece 3, a second carrying device 7 connected to the carrying device 5, and a spreading roller 9. Furthermore, the control apparatus 10 which controls each apparatus is provided.

  The dough piece 3 will be described as a croissant dough cut out in a substantially triangular shape from the wide belt-like dough sheet 2. Here, for convenience of explanation, the top of the substantially triangle is referred to as 3A, the left and right oblique sides are referred to as 3B and 3C, and the bottom is referred to as 3D. The substantially triangular fabric is a concept including a substantially trapezoidal fabric piece in which the length of the top 3A is shorter than the length of the base 3D. A cutting device 25 is provided above the belt conveyor 26 on the upstream side of the dough piece extending device 1. The cutting device 25 shown in FIG. 3 includes a rotary blade 29 having a blade 27 for cutting the oblique sides 3B and 3C on the outer periphery of the cylindrical portion 28, and a round blade for cutting the top portion 3A and the bottom side 3D. The circular cutter 31 is provided.

  Both ends of the rotary shaft 30 of the rotary blade 29 are rotatably supported on a conveyor frame 26F of the belt conveyor 26. A round wheel 33 is fixed to the rotary shafts 30 on both sides of the rotary blade 29. The wheel 33 comes into contact with the conveying surface of the conveyor belt 26B, and is rotated by the friction to drive the peripheral speed of the rotary blade 29 to be the same as the conveying speed of the conveyor belt 26B. Further, the circular cutter 31 is fixed to the rotary shaft 32, and both ends of the rotary shaft 32 are rotatably supported on the conveyor frame 26F. In the circular cutter 31, a round wheel 35 fixed to both ends of the rotary shaft 32 comes into contact with the transport surface of the conveyor belt 26B, and is driven to rotate by friction.

  In this embodiment, the cutting device 25 includes four circular cutters 31 at equal intervals, and is configured to cut the three rows of fabric pieces 3 from the fabric sheet 2 in the width direction.

Furthermore, the actuator 19 can control the vertical movement position.

  Above the first conveying device 5, a photoelectric sensor 23 for detecting the cloth piece 3 to be conveyed is attached. When the sensor 23 detects the cloth piece 3, a detection signal is transmitted from the sensor 23 to the control device 10, and the arithmetic processing unit 37 of the control device 10 calculates the transport position of the cloth piece 3 based on this detection signal, and the position information Based on this, the actuator 19 and an actuator 49 described later are controlled.

  The second transport device 7 is a belt conveyor disposed close to the downstream side of the first transport device 5. The rear end portion 7B of the second conveying device 7 has a conveyor belt 47 hung on a conveyor rear end plate 43 that is swingably supported by a support shaft 41 and a rear end roller 45 that is rotatably attached to the rear end portion. It is configured to be turned. In addition, the conveyor rear end plate 43 is connected to a linear motion type actuator 49 attached in the second transport device 7 via a bracket 51. Accordingly, the rear end portion 7B is provided so as to be able to swing up and down around the support shaft 41 by the reciprocating motion of the direct acting actuator 49. Furthermore, the actuator 49 can control the vertical movement position.

  The extension roller 9 is provided above the rear end portion 7B of the second conveying device 7 with a necessary distance from the conveying surface of the second conveying device 7 (the upper surface of the conveyor belt 47). The extension roller 9 has a rotating shaft 9A arranged in the width direction of the second conveying device 7 (horizontal direction orthogonal to the conveying direction R of the second conveying device 7), and one end of the rotating shaft 9A is a timing belt or the like. It is linked to a control motor 59 through a power transmission mechanism 57. The other end of the rotating shaft 9A is rotatably supported on the upper surface of the conveyor frame 8. Further, the extending roller 9 has a plurality of ridges 9B along the circumferential direction and the same shape and is formed at equal intervals in the axial direction. Here, the protrusion 9B has a trapezoidal shape in the horizontal section. Further, the outer shape portion of the extending roller 9 is an outer periphery 9S, and the bottom of the valley portion between the protruding portions 9B is 9BS.

  The peripheral speed of the extension roller 9 is controlled to be substantially the same as or slightly faster than the transport speed of the second transport device 7. Further, the peripheral speed of the extending roller 9 and the transport speed of the second transport device 7 are controlled to be driven faster than the transport speed of the first transport device 5.

  On the downstream side of the dough piece extending apparatus 1, a hoisting device 61 for winding up the dough piece 103 extended by the dough piece extending apparatus 1 is provided. The hoisting device 61 includes a comb-shaped curl net 63. The curl net 63 is detachably hooked on a span shaft 65 supported by a stand 67 erected on the upper surface of the conveyor frame 8 of the second transport device 7.

  Next, operation | movement of the cloth piece extending apparatus 1 which concerns on 1st embodiment is demonstrated. The dough piece 3 is conveyed by the first conveying device 5 and detected by the sensor 23. The sensor 23 transmits the detection signal to the control device 10. The control device 10 drives the actuators 19 and 49 based on the detection signal to lower the front end portion 5F and the rear end portion 7B (see FIG. 4A). The fabric piece 3 is conveyed without being in contact with the spreading roller 9, and after the bottom 3D of the fabric piece 3 passes below the center of the spreading roller 9 (synonymous with the rotation center of the rotation shaft 9A), the leading end 5F and the rear end The part 7B rises, the dough piece 3 is sandwiched between the extending roller 9 and the conveying surface of the conveyor belt 47, and is extended over the entire length (see FIG. 4B).

When the cloth piece 3 formed into a bent shape with a cylindrical extending roller having no conventional protrusion is extended, the bent piece 3 is extended so as to expand the bent shape as a whole. It is not possible to correct the bending. However, by using the extending roller 9 provided with the protrusion 9B, the bending of the dough piece 3 is corrected and can be formed in a substantially isosceles triangle shape (see FIG. 5). Specifically, this will be described below.

  The extending roller 9 has a plurality of ridges 9B along the circumferential direction and the same shape and is formed at equal intervals in the axial direction. When the dough piece 3 is nipped between the extending roller 9 and the conveying surface of the conveyor belt 17, the dough piece 3 is pressed against the protrusion 9B. The fabric piece 3 is extended at the ridge 9B of the extension roller 9 and also at the bottom 9BS.

When T3, T1> T2> T3, and the fabric piece 3 extends from the initial thickness T1 to be thinner than that. On the upper surface of the fabric piece 3, peaks and valleys corresponding to the interval T2 to T3 are formed, but as a whole, it is formed into a fabric piece 103 that is uniform, that is, the heights of the peaks are substantially uniform.

  The dough of the dough piece 3 is restrained from moving in the width direction at the ridge 9B and stays so as to rise to the upstream side of the extending roller 9. The staying dough 3H is pushed back toward the top 3A inside the dough piece 3 as the dough piece 3 is conveyed. The dough piece 3 is deformed according to the extended length of each part, and the extended dough piece 103 is shaped so as to approximate a substantially isosceles triangle shape.

  A mechanism for deforming the dough piece 3 into a substantially isosceles triangle will be schematically described with reference to FIG. Here, an imaginary line passing through the center of the base 3D of the cloth piece 3 and along the transport direction R is defined as a center line CL. The dough piece 3 shown in FIG. 6A has an aspect in which the top 3A is bent to the right side of the conveyance with respect to the center line CL of the dough piece 3. The cloth lengths at equally spaced positions in the width direction with respect to the center line CL are illustrated. The fabric length corresponding to the fabric piece 3 on the center line is C1, the fabric lengths L1, L2, L3 in order from the center line CL to the left side, the fabric lengths R1, R2, in order from the center line CL to the right side, Let R3. Further, the volume of the fabric on the left side of the center line CL is VL, and the volume on the right side is VR.

  When the dough piece 3 is extended from the bottom 3D side by the extending roller 9 having the protrusion 9B, the dough piece 3 is connected to the upstream side of the extending roller 9 in the width direction of the dough piece 3 so that the staying dough 3H Formed and pushed back to the top 3A side. At this time, the volume VR of the dough 3 on the right side of the center line CL is larger than the volume VL on the left side thereof, so that the staying dough 3H is more in the right part than the left part of the center line CL. Push back more dough than the left side.

  This push-back will be described using the above-described fabric length. Comparing the left and right fabric lengths L1 and R1, L2 and R2, and L3 and R3 of the fabric piece 3 before extending, the fabric lengths that are located on the right side of the center line CL are shown long (FIG. 6 (a)). As described above, since the extending roller 9 includes the protruding portion 9B, the extending cloth piece 3 cannot spread in the width direction. Therefore, the length of the dough of each part is extended according to the amount of the staying dough 3H staying in each part.

  In particular, in the case of a viscoelastic material such as bread dough, the staying dough 3H of each part moves to the top 3A side while pressing each other. And since dough moves to the one where the amount of staying dough 3H is large, the dough of each part does not lengthen proportionally along a conveyance direction. That is, the fabric lengths C1, L1 to L3, and R1 to R3 shown by the fabric piece 3 before the extension are extended by the extension, and as shown in FIG. 6B, the top portion 3A has the center line CL. The dough piece 3 that is deformed and bent so as to be close to is extended into a dough piece 103 having a shape approximately similar to an isosceles triangle and a uniform thickness as a whole.

  As can be understood from the above description, the spreading roller 9 arranges the fabric piece 3 in which the right and left fabric amounts are unevenly formed with respect to the center line CL of the fabric piece 3 so that the fabric amount approaches the left and right evenly. effective. Further, by adjusting the distance between the extending roller 9 and the second conveying device 7, the amount of the staying dough 3H varies, and as a result, the total length (length along the conveying direction) of the extending dough piece 103 is reduced. Can be adjusted. Then, the fabric piece 103 is wound up by the winding device 61 to form the wound fabric 203. By positioning the top portion 3 </ b> A of the fabric piece 103 on the center line CL, the top portion 3 </ b> A can be wound up at the center in the longitudinal direction of the wound fabric 203. That is, by providing the dough piece extending device 1 and the hoisting device 61, the hoisting fabric shaping device is configured as a whole. In the above description, the extension roller 9 has been described as being disposed above the rear end portion 7B of the second conveying device 7. However, the present invention is not limited to this. It is also possible to arrange it above one transport device 5.

  Next, the dough piece extending apparatus 101 according to the second embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the structure which has the same function as the fabric piece extending apparatus 1, and detailed description is abbreviate | omitted. The dough piece extending apparatus 101 has a configuration in which an upstream extending roller 73 is added to the dough piece extending apparatus 1.

  The fabric piece extending device 101 includes an upstream fabric piece extending device 71 and a downstream fabric piece extending device 91. The upstream fabric piece extending device 71 includes a first conveying device 5 and an upstream extending roller 73 above the front end portion 5F of the first conveying device 5. The upstream-side extending roller 73 is provided at a necessary interval from the conveying surface of the first conveying device 5 (the upper surface of the conveyor belt 17). The upstream extending roller 73 has a rotating shaft 74 disposed in the width direction of the first conveying device 5, and one end of the rotating shaft 74 is linked to a control motor 77 via a power transmission mechanism 75 such as a timing belt. ing. The other end of the rotating shaft 74 is rotatably supported on the upper surface of the frame 6.

  In the upstream extending roller 73, a plurality of protrusions 73B along the circumferential direction have the same shape and are formed at equal intervals in the axial direction. The shape of the protrusion 73B can be arbitrarily formed. The peripheral speed of the upstream spreading roller 73 is controlled to be substantially the same as or slightly faster than the transport speed of the first transport device 5.

  The downstream fabric piece extending device 91 includes a second conveying device 7 and a downstream extending roller 93 above the rear end portion 7B of the second conveying device 7. The downstream extending roller 93 is equivalent to the extending roller 9 described above, and a detailed description thereof is omitted.

  Next, operation | movement of the fabric piece extending apparatus 101 which concerns on 2nd embodiment is demonstrated. The fabric piece 3 is conveyed by the first conveying device 5 of the upstream fabric piece extending device 71 and detected by the sensor 23. The sensor 23 transmits the detection signal to the control device 10. Based on the detection signal, the control device 10 drives the actuators 19 and 49 to lower the front end portion 5F and the rear end portion 7B (see FIG. 9A). The fabric piece 3 is conveyed without being in contact with the upstream-side extending roller 73 and the downstream-side extending roller 93, and after the bottom 3D of the fabric piece 3 passes below the center of the downstream-side extending roller 93, the front end portion 5F and the rear end The part 7B rises and the dough piece 3 is sandwiched between the upstream spreading roller 73 and the conveying surface of the conveyor belt 17 and between the downstream extending roller 93 and the conveying surface of the conveyor belt 47. (See FIG. 9B).

  Next, the operation of the upstream side extension roller 73 and the downstream side extension roller 93 will be described. In the upstream side fabric piece extending device 71, the upstream side extending roller 73 provided with the ridge 73B is bent approximately in the same manner as the extending roller 9 in the above described fabric piece extending device 1 and is about the upper half of the fabric piece 3 formed. There is an effect of correcting the portion so as to approximate a substantially isosceles triangle shape. Moreover, since the conveyance speed of the 2nd conveyance apparatus 7 of the downstream side fabric piece extending apparatus 91 is controllable and is set larger than the conveyance speed of the 1st conveyance apparatus 5, the upstream side extension roller 73 and the downstream side extension roller The cloth between 93 is stretched along the transport direction R. Further, after the fabric piece 3 has passed below the upstream side extension roller 73, the downstream side extension roller 93 acts to correct the bending of the fabric piece 3.

  The dough piece extending apparatus 101 has an upstream dough piece extending apparatus 71 and a downstream dough piece extending apparatus 91 connected in close proximity to each other in the conveying direction, and the peripheral speed of the downstream extending roller 93 is set to the peripheral speed of the upstream extending roller 73. By controlling faster, the dough piece 3 can be stretched and stretched in the transport direction R, and the bend of the dough piece 3 can be corrected twice, so that the bent dough piece 3 can be efficiently formed into an isosceles triangle shape. It can form so that it may approach. Then, the extended fabric piece 105 is wound up by the winding device 61, and the rolled-up fabric 205 is formed. The wound dough 205 can be wound into the center of the longitudinal direction of the top 3A of the dough piece 3, and the wound shape is formed into a symmetrical spindle shape. In other words, the roll dough shaping device is configured as a whole by including the dough piece extending device 101 and the roll raising device 61.

  Next, the extension roller 111 according to the third embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the structure which has the same function as the fabric piece extending apparatus 1, and detailed description is abbreviate | omitted. The extension roller 111 is different in configuration from the extension roller 9.

  The extension roller 111 is provided so as to be movable on a placing table 121 on which the fabric piece 3 is placed. In the cloth piece extending apparatus 1 described above, the cloth piece 3 has been described as being conveyed by the first conveying apparatus 5 and the second conveying apparatus 7 and extended by the extending roller 9 fixed in the conveying direction R. However, when the dough piece 3 is extended, the dough piece 3 and the extending roller need only move relatively. The mounting table 121 may be a conveyance device such as a belt conveyor that is intermittently conveyed. Furthermore, both the spreading roller 111 and the mounting table 121 may be movable. The mounting table 121 is relatively movable.

  The extending roller 111 is provided so as to rotate by a driving mechanism (not shown) so as to extend the cloth piece 3 and to be movable from the bottom 3D side to the top 3A side of the cloth piece 3. The extension roller 111 may be configured such that the main body portion of the extension roller 111 can rotate with respect to the rotation shaft 111A. The extension roller 111 has a round shape having a diameter larger than the outer periphery 111S of the extension roller 111 at both ends of the main body of the extension roller 111. A flange 111 </ b> F may be provided and rotated by friction with the mounting table 121.

  The extending roller 111 has a shape in which a plurality of substantially semicircular ridges 111B are provided in the width direction (the axial direction of the extending roller 111), and adjacent protrusions 111B are connected by a concave semicircle. That is, the surface shape of the extension roller 111 is formed in a waveform. When the extending roller 111 is moved while rotating from the bottom 3D side to the top 3A side of the fabric piece 3, the fabric piece 3 is extended at the ridge 111B of the extending roller 111 and also at the bottom 111BS. In the dough piece 3, a staying dough 3H is formed on the upstream side in the movement direction of the spreading roller 111 in the width direction of the dough piece 3, and the staying dough 3H is pushed back to the top 3A side. Then, the dough piece 3 that is bent to one side with respect to the center line CL is corrected so as to approach a substantially isosceles triangle.

The lifting device 411 is attached to a first span shaft 415 supported between both stands 413. The elevating device 411 includes a direct-acting actuator 417 such as a fluid pressure cylinder, and a bracket 419 that rotatably supports the extending roller 410 at the tip of a reciprocating rod 417R. Further, a sensor 23 for detecting the dough piece 3 conveyed to the upstream side of the lifting device 411 is attached. Based on the detection signal of the sensor 23, the control device 10 calculates the transport position of the dough piece 3, and controls the driving of the actuator 417 based on the position information.

  The extending roller 410 is arranged with its rotation shaft 410A parallel to the conveying surface of the first conveying device 405 and along the width direction of the first conveying device 405. The extending roller 410 has a drum shape with a central portion in the longitudinal direction being thinner than both end portions. This extending roller 410 is provided with protrusions 410B at both ends, and is provided with a bottom 410BS at a valley portion between them through a slope 410C. The extension roller 410 moves up and down relatively with respect to the transport surface (upper surface) of the first transport device 405 by the reciprocating motion of the actuator 417 and moves toward and away from each other. When the extending roller 410 is lowered, the extending roller 410 is positioned above the front end roller 421 of the first conveying device 405. The descending stop position of the extending roller 410 is provided so that the entire extending roller portion 409 can be adjusted in the vertical direction, or can be adjusted by controlling the stroke of the rod 417R of the actuator 417.

  The winding unit 425 of the winding device 423 includes two rotating wheels 431, a winding sheet 433 made of a deformable flexible member, and a pressing plate 434 that presses the upstream side of the winding sheet 433. The rotating wheel 431 has a gap that allows the dough piece 3 to be pressed against the conveyance surface of the second conveyance device 407, and is provided so as to be movable up and down to adjust the gap. The rotating wheel 431 is attached to a rotating shaft 435 that is rotated by a pair of rotating driving wheels 437 via a pulley and belt rotation transmission mechanism 439, and is substantially the same as or slightly faster than the conveying speed of the second conveying device 407. It is rotated by. The drive wheel 437 contacts the surface of the conveyor belt 407B and is rotated by the friction.

  The roll-up sheet 433 has a substantially strip shape, and a fine uneven surface is formed on the lower surface in contact with the fabric piece 3. A substantially V-shaped notch 433A is formed in the upstream portion of the wound sheet 433 in order to avoid interference with the rotating wheel 431. The wound sheet 433 is formed with a pair of arms 433B at both ends of the notch 433A and a long hole 433C along the transport direction R in the center of the downstream portion of the notch 433A. A substantially U-shaped hooking member 440 is attached to the tip of the arm portion 433B. Further, the second span shaft 441 is supported between the stands 413 and shafts a rectangular parallelepiped hooked member 442. The winding sheet 433 is such that the hooking member 440 is detachably hooked on the hooked member 442, and the second conveying device 407 conveys from the lower end of the arm portion 433B to the downstream side portion of the hoisting sheet 433. It becomes the aspect mounted on the surface.

  The arm portion 433 </ b> B of the winding sheet 433 is pressed from above by a pressing plate 434 attached to the second span shaft 441. The presser plate 434 prevents the hoisting sheet 433 from floating when both side portions of the bottom 3D of the dough piece 3 are in contact with the arm portion 433B of the hoisting sheet 425, thereby ensuring that the dough piece 3 is rolled up. It is. The pressing plate 434 is provided so that the vertical position can be adjusted according to the thickness of the fabric piece 3 to be conveyed. In this embodiment, when the second span shaft 441 is moved up and down, the rotating wheel 431, the upstream portion of the winding sheet 433, and the pressing plate 434 move up and down integrally.

  The winding portion 427 is composed of three deformable flexible members along the transport direction R, and a strip-shaped sheet member 443 having fine irregularities formed on the lower surface is arranged in parallel in the width direction, and above them, respectively. A wrapping sheet 446 formed integrally with a metal strip-like net member 445 is provided. The sheet member 443 and the net member 445 in each row are coupled to each other at a plurality of locations by a ring-shaped coupling member 447, and adjacent rows are coupled together. At the upstream end of each sheet member 443 and net member 445, that is, at the upstream end of the winding sheet 446, a hook member 448 is attached and the hook member 450 of the third span shaft 449 supported by the stand 413. It is detachably hooked on. The sheet member 443 and the net member 445 are not limited to three, and may be a plurality of two or more, and can be formed even if the width of each member is not the same. The winding sheet 446 is desirably formed symmetrically in the width direction.

  The downstream portion of the sheet member 443 and the net member 445 is formed in a bifurcated shape without being connected to the top and bottom, and the downstream portion of the sheet member 443 is placed on the transport surface of the second transport device 407. Further, a latch member 448 is attached to the downstream end portion of each net member 445, and is detachably latched on the latch member 450 of the fourth span shaft 453 supported by the stand 451. The intermediate portion of the winding sheet 443 is placed on the downstream portion of the winding sheet 433 and the transport surface of the second transport device 407, and follows the shape of the roll-up fabric 205 that passes while rolling on the lower surface thereof. It can be deformed. Note that the stand 451 is attached to the side surface of the second transport device 407.

  A guide plate 455 is attached to the third span shaft 449 for guiding both sides from the upstream end portion of the tightening sheet 446 to the intermediate portion thereof. In the present embodiment, the guide plate 455 also sandwiches the downstream portion of the winding sheet 433 from both sides to prevent the winding sheet 446 and the winding sheet 433 from being displaced in the width direction.

  The shaping part 429 is made of a deformable flexible member, and includes a rectangular shaping sheet 457 having fine irregularities formed on the lower surface. The upstream end of the shaping sheet 457 is attached to a latching member 448 attached to the downstream end of the net member 445. Further, a latching member 448 is attached to the downstream end of the shaping sheet 457, and is detachably latched on the latched member 450 of the fifth span shaft 459 supported by the stand 451. The intermediate portion of the shaping sheet 457 is placed on the conveyance surface of the second conveyance device 407.

  In the intermediate portion of the shaping sheet 457, a long hole 461 is formed along the longitudinal direction (left and right direction in FIG. 15, conveyance direction R) at the center in the width direction in plan view. A rectangular pressing plate 463 is attached to the shaping sheet member 457 on both sides of the downstream portion of the long hole 461. Two bar-like members 465 are erected on the upper surface of each pressing plate 463. A plate-like weight 467 can be detachably stacked on the pressing plate 463 via the rod-like member 465.

  Guide plates 469 that guide both sides of the intermediate portion of the shaping sheet 457 are attached to the fourth span shaft 453. The guide plate 469 prevents the shaping sheet 457 from being displaced in the width direction.

  Next, the operation of the wound dough shaping apparatus 401 according to the fourth embodiment will be described. The dough piece 3 is conveyed by the first conveying device 405 and detected by the sensor 23. The sensor 23 transmits the detection signal to the control device 10. Based on the detection signal, the control device 10 drives the actuator 407 of the extension roller unit 409 to lower the extension roller 410 (see FIG. 12). In the present embodiment, the lowering timing of the spreading roller 410 will be described as immediately after the bottom 3D of the dough piece 3 is sandwiched between the rotating wheel 431 and the transport surface of the second transport device 407.

  Next, the operation of the extension roller unit 410 and the winding device 423 will be described. The spreading roller 410 nips the portion on the top 3A side of the dough piece 3 with the conveying surface of the first conveying device 405, and extends the dough toward the top 3A (see FIG. 16). The cloth on the top 3A side portion of the cloth piece 3 is restrained from moving in the width direction at the protrusions 410B at both ends of the extending roller 410 and stays so as to rise upstream of the extending roller 410. Become. The staying dough is pushed back to the top 3 </ b> A side inside the dough piece 3 as the dough piece 3 is conveyed. The fabric piece 3 is subjected to the action of pushing back by the inclined surface 410C of the extending roller 410, and the top portion 3A of the fabric piece 3 is deformed so as to approach the center line CL, and the portion on the top portion 3A side of the bent fabric piece 3 is bent. Is shaped so as to approximate a substantially isosceles triangle shape. By positioning the top portion 3A of the dough piece 3 on the center line CL, the top portion 3A can be wound up at the center in the longitudinal direction of the wound fabric 207 at the time of winding in the subsequent process.

  The dough piece 3 is extended by the extending roller 410 while being pulled in the conveying direction R between the extending roller 410 and the rotating wheel 431 by the speed difference between the first conveying device 405 and the second conveying device 407. Since the dough piece 3 is in contact with the winding sheet 433 of the winding unit 425 while being pressed against the second conveying device by the rotating wheel 431, both sides of the bottom 3D of the dough piece 3 do not slip on the second conveying device. It is wound up toward the upstream side. Since the wound fabric 207 is wound in a state where tensile stress is generated inside the fabric, the wound fabric 207 is formed in a relatively strong state. The length of the stretched fabric piece can be adjusted according to the degree of pressing of the extension roller 410, that is, the distance between the extension roller 410 and the first conveying device 405. Thus, the number of windings of the rolled up fabric 207 can be adjusted.

  The wound up fabric 207 is transported by the second transport device 407 while rolling below the wound sheet 433. The downstream side portion of the winding sheet 433 is covered with the winding sheet 446 and is deformed into a mountain shape in the width direction and the conveyance direction so as to follow the shape of the winding cloth 207. The fabric in the vicinity of the top portion 3 </ b> A of the wound fabric 207 is guided by the long hole 433 </ b> C of the wound sheet 433 and is positioned at the center of the wound fabric 207. Further, the roll-up sheet 433 is provided with the long holes 433C, so that both side portions of the long holes 433C are easily deformed in an inclined shape so as to follow the shape of the roll-up dough 207, and the roll-up dough 207 can be shaped into a symmetrical spindle shape.

  The wound dough 207 is further tightened by an intermediate portion of the tightening sheet 446 to strengthen the winding. The net member 445 of the winding sheet 446 is made of metal and acts as a weight for the rolled up fabric 207. As described above, the winding sheet 446 has the three sheet members and the net member arranged in parallel in the width direction and overlapped with each other by the coupling member 448. It can be flexibly deformed in the conveying direction, and the wound dough 207 can be wound into a symmetrical spindle shape. By changing the weight of the net member 445, the degree of deformation of the winding sheet 446 to a mountain shape with respect to the rolled-up cloth 207 can be adjusted, and the degree of tightening of the rolled-up cloth 207 can be adjusted.

  The rolled-up fabric 207 that has passed through the tightening unit 427 is conveyed to the shaping unit 429. The wound dough 207 is in contact with the intermediate portion of the shaping sheet 457 and is conveyed by the second conveying device 407 while rolling. The shaping sheet 457 can be deformed by providing the long holes 461 so that both sides thereof conform to the surface shape of the rolled-up fabric 207. Further, the shaped sheet 457 guides the fabric in the vicinity of the top 3A of the rolled-up fabric 207 to the center in the longitudinal direction of the rolled-up fabric 207. It can be shaped without crushing.

  In the above description, the guide plate 455 and the guide plate 469 are provided to prevent the winding sheet 433, the winding sheet 446, and the shaping sheet 457 from being displaced in the width direction. Since the roll-up dough 207 can be rolled without these sheets being displaced in the width direction, the roll-up dough 207 can be shaped into a symmetrical spindle shape. Note that in the case where the tightening of the wound dough 207 is relatively weak, it is possible to provide a winding device that does not constitute a part of the winding unit 425, the winding unit 427, or the forming unit 429. For example, in the case where a filling such as jam or cream is placed on the upper surface of the dough piece 3 and a roll-up dough containing the filling is formed inside, if the roll-up dough is tightened too much, the filling may leak to the surface. There is a need to adjust the strength of the tightening.

  Next, an application example of the winding unit will be described with reference to FIG. The above-described winding device 423 is provided in the vicinity of the downstream side of the extending roller unit 409 and has been described so as to wind the fabric piece 3 while pulling it in the transport direction R. The winding unit 471 shown in FIG. 17 can be replaced with the winding unit 425 of the winding device 423. Further, the present invention is not limited to this, and it is also possible to wind up the fabric piece 3 or the fabric piece stretched by another device using only the winding unit 471. The winding portion 471 includes four rolling plates 473 rotatably supported by the second span shaft 441, three rotating wheels 431 supported by the rotating shaft 435, and a deformable flexible member attached to the rolling plate 473. The winding sheet | seat 475 which consists of is provided. The rolling plate 473 is provided in parallel in the width direction, and a rotating wheel 431 is disposed between them.

  The rolling plate 473 is provided with a bent arm member 477, and the arm member 477 is disposed on the conveying surface and an abutting portion 478 that is inclined from the second span shaft 441 toward the conveying surface of the second conveying device 407. On the other hand, a rolling part 479 whose downstream side is oriented slightly upward is provided. On the lower surfaces of the contact part 478 and the rolling part 479, a lattice-shaped uneven surface for increasing the contact resistance with the fabric piece 3 is formed. The compaction plate 473 is disposed on the stopper shaft 485 so that the arm member 477 is slightly spaced from the transport surface of the second transport device 407.

  The roll-up sheet 475 is attached to the tip end portion (downstream end portion) of the rolling pressure portion 479 of the four rolling pressure plates 473. The wound sheet 475 includes an isosceles triangular opening 481 immediately downstream of the tip of the rolling part 479, and arm parts 482 on both sides of the opening 481. Further, deformable rod-shaped weight members 483 are attached to both ends of the winding sheet 475. Further, the wound sheet 475 includes a cut line 484 that penetrates along the transport direction R in the center of the wound sheet 475 on the downstream side of the opening 481.

  Next, a method for winding the dough piece 3 by the winding unit 471 will be described. The dough piece 3 conveyed to the second conveying device 407 is pressed by the rotating wheel 431, and the bottom 3 </ b> D of the dough piece 3 comes into contact with the lower end portion of the contact portion 478 of the compaction plate 473 waiting at the lowest position. The dough piece 3 pushes up the rolling plate 473 while being conveyed, and the base 3D rises upward. The dough piece 3 is wound up by the arm portions 482 at both ends of the opening 481 of the rolled-up sheet 475 on the lower surface of the rolling unit 479. The wound up fabric 207 is wound up relatively lightly at the downstream portion of the wound sheet 475. At this time, the roll-up sheet 475 can be deformed so that both sides thereof conform to the surface shape of the roll-up dough 207 by providing a cut line 484 at the center thereof. Further, in the latter half of the winding, the rolled-up fabric 207 that has passed through the uneven surface on the lower surface of the rolling member 479, which is a rigid body, is rolled up by a lightweight and flexible rolled-up sheet 475, so that the surface can be kept clean.

  As a conventional winding device, there is a winding device described in Patent Document 2. This winding device is a device for winding up the dough piece from both ends of the bottom of the dough piece and for stretching both arms (both sides of the spindle shape) of the rolled up dough in the longitudinal direction of the dough roll. Japanese Utility Model Publication No. 63-37824 discloses a curl net in which a plurality of rod-shaped rods are attached in parallel to two parallel cables. This curl net can swing and bend with respect to the wound fabric to increase the contact area. However, in these conventional techniques, the winding device cannot be brought into contact with the surface shape of both arms of the rolled fabric, and the rolled fabric may not be formed into a symmetrical spindle shape. However, the winding sheet 433, the winding sheet 446, the shaping sheet 457, and the winding sheet 475 of the winding unit 471 that constitute the winding device 423 are all capable of inclining the respective sheets downward toward both ends of the winding fabric 207. Since it is formed, both arms of the roll-up cloth 207 can be pressed symmetrically in the width direction from above, so that the roll-up cloth 207 can be shaped into a symmetrical spindle shape.

  In the present embodiment, the fabric piece spreading device 403 and the hoisting device 423 have been described as including the first conveying device 405 and the second conveying device 407, respectively. It is not limited to such a form, The dough piece extending device 403 and the winding device 423 may be provided with a common conveying device, that is, one conveying device.

The wound dough shaping apparatus 501 includes a dough piece extending device 403 and a winding device 503 on the downstream side thereof. The dough piece extending device 403 includes a first conveying device 405 and an extending roller unit 409 above the first conveying device 405. The winding device 503 includes a second transport device 407 and a rear end side of the second transport device 407 and a winding unit 505 above the second transport device 407. Furthermore, the control apparatus 10 (illustration omitted) which controls each apparatus is provided. Moreover, in this embodiment, a food material such as chocolate, which is a bar-like solid inner material 6, is placed on the upper surface on the bottom 3D side of the dough piece 3 to be conveyed. In the following description, it is assumed that the rolled-up fabric 209 containing the inner material 6 is shaped.

  The extending roller 410 of the extending roller unit 409 can be adjusted in its lower end position by providing a first actuator 417 that moves the extending roller 410 up and down so as to move up and down. Specifically, the actuator 417 is attached to the vertical handle mechanism 514 provided on the stands 413 on both sides via the base bracket 515. The sensor 23 for detecting the passage of the fabric piece 3 is attached to a span shaft 502 fixed between the stands 413 on both sides. The control device 10 calculates the transport position of the dough piece 3 based on the detection signal of the sensor 23, and controls the driving of the first actuator 417, the second actuator 529 described later, and the control motor 543 based on the position information.

  The hoisting unit 505 of the hoisting device 503 includes three rotating wheels 431 arranged in parallel in the width direction at a required interval, a support mechanism 508 that is rotatably attached to the shaft 507, and a rolling mechanism that is detachably supported by the support mechanism 508. A roll-up sheet 511 made of a deformable flexible member attached to the pressure plate 509 and the rolling plate 509 is provided.

  The rotation wheel 431 is driven by a rotation of a control motor 543 via a rotation transmission mechanism 541 such as a V belt and a V pulley so that the rotation speed can be adjusted. Further, the rotating wheel 431 is provided so as to be lifted and lowered by a lifting device 527. The lifting device 527 moves the rotary shaft 435 up and down via a power transmission mechanism 531 such as a link mechanism to a direct acting second actuator 529 using an air cylinder or the like attached to a stand 413. The arm portion 532 of the link mechanism 531 is provided with a plurality of connection holes 532H, and the elevation distance of the rotating wheel 431 can be increased or decreased by changing the connection position of the actuator 529. Further, by connecting the rotation shaft 435 to the up / down handle mechanism 533, an operating position (the rising end position to the falling end position) where the rotating wheel 431 moves up and down is provided.

  The support mechanism 508 includes a mounting bracket 521 that is rotatably attached to the shaft 507 and detachably supports the rolling plate 509, and a bracket 523 that is fixed to the shaft 507 so that the rotational position can be adjusted. A damper 525 for urging the rolling plate 509 toward the second transport device 407 is attached to the bracket 523.

  The rolling plate 509 has a bent shape, and is bent from the arm portion 516 inclined toward the downstream side in the conveying direction R with respect to the conveying surface of the second conveying device 407 from the support mechanism 508 side, and further inclined. The contact part 517 and the rolling part 518 whose downstream side is directed slightly upward with respect to the transport surface are provided. The upper half of the rolled-up sheet 511 is affixed to the lower surfaces of the contact part 517 and the rolling part 518. On the lower surface of the rolled-up sheet 511, a lattice-shaped uneven surface for increasing the contact resistance with the fabric piece 3 is formed. Also, deformable weight members 519 are attached to both ends of the upper surface of the lower half of the rolled-up sheet 511. The rolling plate 509 and the rolled-up sheet 511 are provided with long holes (not shown) through which the rotating wheel 431 can pass in parallel in the width direction. Further, the rolling plate 509 is provided so as to be movable relative to the rotating wheel 431 by adjusting the movement of the shaft 502 supporting the support mechanism 508 along the transport direction R.

  Next, a typical example relating to a method for winding the dough piece 3 on which the inner material 6 is placed by the roll-up dough shaping device 501 will be described. In the first example relating to the method of winding the dough piece 3 on which the inner material 6 is placed, the dough piece 3 is conveyed by the first conveying device 405, and the sensor 23 detects the dough piece 3. Further, the fabric piece 3 is conveyed, and after the inner material 6 passes below the spreading roller 410, the first actuator 417 of the lifting device 411 is actuated to lower the spreading roller 410 and press the fabric piece 3. While the dough piece 3 is being conveyed, the bottom 3D is brought up against the contact portion 517 of the rolling plate 509. At substantially the same time, the inner member 6 contacts the rotating wheel 431 that rotates at the rising end position. The rotating wheel 431 guides the inner material 6 in the conveying direction R while pressing the dough piece 3 against the conveying surface of the second conveying device 407 via the inner material 6. Therefore, the contact portion 517 winds the bottom 3D of the fabric piece 3 around the inner material 6 held by the rotating wheel 431, and the inner material 6 can be prevented from rolling off from the fabric piece 3.

  When the inner material 6 passes through the lower end portion of the rotating wheel 431, the second actuator 529 of the lifting device 527 is actuated to lower the rotating wheel 431 to a position where it contacts the dough piece 3. The upstream side of the dough piece 3 is pulled between the spreading roller 410 and the rotating wheel 431, and the downstream side of the dough piece 3 is wound up by the rolling plate 509. The rolling plate 509 rotates upward according to the outer shape of the fabric piece 3 to be wound up and is urged by the damper 525, so that the rolled up fabric 209 is wound around the inner material 6 without any gaps, and The fabric is rolled up in a state where the fabrics are in close contact. The rolled up fabric 209 passes under the rolled sheet 511 while rolling.

  As described above, since the operation position of the rotating wheel 431 can be adjusted, the rising end position and the falling end position can be appropriately set according to the size of the inner member 6 and the thickness of the fabric piece 3. Further, since the rolling plate 509 is provided so as to be movable in the conveying direction R with respect to the rotating wheel 431, the rolling plate 509 holds the dough piece 3 almost simultaneously with the rotating wheel 431 pressing the inner material 6 against the dough piece 3. Can be adjusted to raise. In this way, by making it possible to individually adjust the rotating wheel 431 and the rolling plate 509, the dough piece 3 on which the inner material 6 is placed can be stably wound up and shaped. The winding device 503 is not limited to the substantially triangular fabric piece 3, and can wind up the wound fabric by winding a rectangular fabric piece around the inner material. Further, in the case where the cloth piece extending devices are provided close to each other, it is more effective to replace the extending roller 410 with a long one such as the extending roller 9 so as to hold down the entire width of the cloth piece.

  Next, the 2nd example regarding the winding-up method of the fabric piece 3 in which the inner material 6 was mounted is demonstrated. In the second example, the speed of the second transport device 407 may be set faster than the speed of the first transport device 405. In the second example, the cloth piece 3 is detected by the sensor 23 as in the first example. When the base 3D of the dough piece 3 is transferred from the first transport device 405 to the second transport device 407, the base 3D is raised, and the inner member 6 contacts the rotating wheel 431.

  Here, by setting the outer peripheral speed of the rotating wheel 431 slower than the conveying speed of the second conveying device, a force for winding the dough piece 3 around the inner material 6 acts, and the dough is wound around the inner material 6. The piece 3 is wound. Then, the fabric piece 3 is further conveyed in the conveyance direction R, and after the inner material 6 passes through the lower end portion of the rotating wheel 431, the extending roller 410 descends and presses the fabric piece 3. Then, the bottom 3D of the dough piece 3 is further wound up in contact with the contact portion 517 of the rolling plate 509. Further, after the inner material 6 passes through the lower end portion of the rotating wheel 431, the rotating wheel 431 descends to a position where it comes into contact with the fabric piece 3. At this time, since the speed of the second transport device 407 is set higher than the speed of the first transport device 405, the dough piece 3 is pulled and stretched.

  Next, the 3rd example regarding the winding-up method of the fabric piece 3 in which the inner material 6 was mounted is demonstrated, referring FIG. FIG. 20 continuously shows the state of each device in the third example relating to the winding method of the dough piece 3 on which the inner material 6 is placed. In the third example, in the wound dough shaping apparatus 501 according to the fifth embodiment, a winding sheet 446 is used instead of the winding sheet 511. In the third example, (a) the transport surface height of the second transport device 407 is made higher than the transport surface height of the first transport device 405, and (b) the second transport device from the speed of the first transport device 405. Settings such as increasing the speed of 407 and (c) reducing the outer peripheral speed of the rotating wheel 431 from the conveying speed of the second conveying device 407 may be performed independently or in combination.

  In the third example, the cloth piece 3 is detected by the sensor 23 as in the first example. As shown in FIG. 20 (a), when the dough piece 3 on which the inner material 6 is placed is transferred from the first transfer device 405 to the second transfer device 407, the bottom 3D side of the dough piece 3 hangs down slightly. Thereafter, the base 3D comes into contact with the shoulder of the rear end roller of the second transport device 407. Then, as shown in FIG. 20 (b), the base 3D side of the dough piece 3 is moved upward due to the difference in the height of the conveyance surface and / or the conveyance speed between the first conveyance device 405 and the second conveyance device 407. Turn towards.

  As shown in FIG. 20C, the fabric piece 3 (the bottom 3D or the lower surface of the fabric piece 3) is in contact with the rotating wheel 431, and the fabric piece 3 and the inner material 6 are between the rotating wheel 431 and the second transport device 407. The dough piece 3 is wound around the inner member 6 in a state of being sandwiched between the inner member 6 and the inner member 6. At this time, the rolling of the dough piece 3 is urged by the speed difference between the second conveying device 407 and the rotating wheel 431. Next, as shown in FIG. 20 (d), the fabric piece 3 wound around the inner material 6 contacts the contact portion 517 of the compaction plate 509, and the fabric piece 3 is conveyed by the compaction plate 509 while being conveyed. Rolled up around.

  Moreover, as shown in FIG.20 (e), the extending roller 410 descends and presses the dough piece 3. FIG. At this time, a pulling force along the transport direction acts on the dough piece 3 due to a transport speed difference between the first transport device 405 and the second transport device 407. Further, the extending roller 410 corrects the cloth piece 3 so as to approach a substantially isosceles triangle. Next, as shown in FIG. 20 (f), the rotating wheel 431 descends and presses the dough piece 3. The rotating wheel 431 prevents the inclination in the horizontal plane with respect to the conveyance direction of the dough piece 3. The downstream side of the dough piece 3 is wound up by a rolling plate 509. Further, as shown in FIG. 20 (g), after the fabric piece 3 is wound up by the tightening sheet 446, the extending roller 410 and the rotating wheel 431 return to the initial positions, and the next fabric piece 3 is conveyed. Wait for.

  As can be understood from the above description, in the third example, the winding process is started between the first transport device 405 and the second transport device 407. And the rotating wheel 431 is arrange | positioned downstream from the starting position of this winding-up process. Therefore, the device for winding up the dough piece 3 and the rotating wheel 431 that contacts the dough piece 3 and presses against the second conveying device are arranged in parallel.

  As a conventional example of a hoisting device that places a solid material on the upper surface of a dough piece and winds it up, there is an apparatus described in No. 3058292 filed by the present applicant. In this conventional apparatus, a plurality of compaction plates are arranged in parallel in the width direction above the conveying surface of the conveyor, and each compaction plate is pivotally supported by a shaft. This conventional apparatus is an apparatus for shaping a rolled dough having a bar-shaped solid as a core material by allowing a bread dough piece on which the bar-shaped solid is placed to pass through a winding space and a conveying surface of the rolling plate. . In this apparatus, before rolling up the bread dough pieces so that they do not roll off from the bread dough, the stick solids are sufficiently pressed and brought into close contact with the bread dough by a known means, and the dough is rolled by the rolling plate with the rolling plate. Roll up a piece. Therefore, there is a problem that the bar-shaped solid material rolls on the dough piece and the dough piece does not roll up.

  Another conventional example is an apparatus described in European Patent No. 1726029. This conventional apparatus is provided with a pressing device that opposes the upper side of the conveyor belt and a winding conveyor on the downstream side thereof, and forms a pressing passage and a winding passage. The pressing device and the hoisting conveyor are belt conveyors in which a plurality of endless belts separated in the width direction are respectively wound around, and are driven by individual drive motors. In this conventional apparatus, since the pressing passage and the winding passage are individually provided, there is a problem that the apparatus is enlarged. Also, in the winding path, the dough piece is rolled up by the hoisting conveyor without rolling the dough piece and the dough piece is wound up, so that the take-up becomes unstable, and when croissant dough is rolled up, it is formed into a symmetrical spindle shape There are problems such as being unable to do so.

  In the winding device 503 in the present embodiment, when the rolling plate 509 winds up the dough piece 3, the rotating wheel 431 presses the dough piece 3 directly through the inner material 6, and the inner material 6 is placed. The dough piece can be wound up stably, and a symmetrical and spindle-shaped dough roll 209 can be shaped. Accordingly, it is possible to wind up the fabric piece 3 on which the inner material 6 is placed by only the winding device 503 without winding up the fabric piece spreading device 403. In addition, the roll-up dough shaping device 501 can roll up the dough piece 3 between the pressing roller 410 and the rotating wheel 431, and therefore adjusts the number of rolls and the strength of the roll of the roll-up dough 209. It is something that can be done.

  In the present embodiment, the dough piece extending device 403 and the winding device 503 have been described as including separate conveying devices of the first conveying device 405 and the second conveying device 407, respectively. It is not limited to such a form, The dough piece spreading device 403 and the winding device 503 may be provided with a common conveying device, that is, one conveying device.

  Further, in this embodiment, when the dough piece 3 on which the inner material 6 is placed is rolled up, the inner material 6 is placed near the bottom 3D side of the dough piece 3 by hand or machine. In order to facilitate positioning of the dough piece 3 and prevent the position of the inner material 6 from being displaced during the roll-up molding of the dough piece 3, as shown in FIG. (Grooves) 3E may be formed in advance, and the inner member 6 may be placed in the recesses 3E.

  Next, a fabric piece spreading device 601 according to a sixth embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the structure which has the same function as the said description, and detailed description is abbreviate | omitted. The dough piece extending apparatus 601 includes a first conveying apparatus 405, a second conveying apparatus 407, an extending roller section 409 as an upstream extending roller section, and a downstream extending roller section 603. Furthermore, the control apparatus 10 which controls each apparatus is provided.

  The extension roller unit 409 is provided above the front end side of the first conveying device 405 in the same manner as the dough piece extending device 401. The extension roller 410 moves toward and away from the transport surface (upper surface) of the first transport device 405 by the reciprocating motion of the actuator 417. Further, the downstream side extension roller section 603 includes an extension roller 9. The extension roller 9 is provided on the rear end side of the second transport device 407 and above it. The extension roller 9 is attached to the transport surface (upper surface) of the second transport device 407 with a predetermined interval.

  The dough piece 3 is conveyed by the first conveying device 405 and detected by the sensor 23. Further, the dough piece 3 is conveyed, passes below the extending roller 410 waiting upward, and is sandwiched between the extending roller 9 and the conveying surface of the second conveying device 407. Thereafter, based on the detection signal from the sensor 23, the control device 10 drives the actuator 417 to lower the extending roller 410 to a required position. The extending roller 410 presses the cloth piece 3 against the conveying surface of the first conveying device 405 and extends the cloth on the top 3 </ b> A side of the cloth piece 3.

  The extending roller 410 has an effect of correcting the approximately upper half of the bent fabric piece 3 so as to approximate a substantially isosceles triangular shape. Further, since the transport speed of the second transport device 407 is set to be larger than the transport speed of the first transport device 405, the cloth between the upstream side extension roller 410 and the downstream side extension roller 9 is in the transport direction R. Is stretched along. Further, after the fabric piece 3 passes below the spreading roller 410, the spreading roller 9 acts to correct the bending of the fabric piece 3. Since the fabric piece 109 extended in this way is formed into a substantially isosceles triangle shape, the top 3A of the fabric piece 109 is wound up to the center in the longitudinal direction of the wound fabric formed by winding up the fabric piece 109. Can be formed into a symmetrical spindle shape.

  In the fabric piece extending apparatus 101, the bottom side 3 </ b> D of the downstream side extension roller 93 is prevented from contacting the bottom side 3 </ b> D of the fabric piece 3 with the downstream side extension roller 93 when the fabric piece 3 is extended by the downstream side extension roller 93. Although it has been described that the downstream side extension roller 93 and the second conveying device 7 are relatively approached after passing below the center to sandwich the dough piece 3, the dough piece extending device 601 approaches in advance and has a predetermined interval. The fabric piece 3 is transported between the extending roller 9 and the second transporting device 407 arranged in the above. For example, when a relatively hard cloth or the like is extended, even if the base 3D of the cloth piece 3 is slightly inclined with respect to the width direction, the inclination does not change greatly even if it contacts the extension roller 9. The dough piece 3 can be formed into a substantially isosceles triangle shape by the action of the protrusion 9B of the roller 9.

  The description of the extension device according to the embodiment of the present invention is generally as described above, but the present invention is not limited to this, and various modifications can be made within the scope of the claims. For example, although it has been described that the upstream extension roller is provided above the first conveyance device and the downstream extension roller is provided above the second conveyance device, both extension rollers are provided above the single conveyance device. It is also possible. Even in this case, the dough piece 3 can be formed into a substantially isosceles triangle shape.

  Further, it is possible to provide a hoisting device 423 and a hoisting device 503 close to or away from the downstream side of the dough piece spreading device 1, 101 or 601, and the hoisting fabric shaping device as a whole can be provided. Is possible.

Further, although the extending roller 410 has been described as a drum shape, three or more protrusions may be provided in the longitudinal direction like the extending roller 9. Moreover, although the some protrusion part of the extending roller was demonstrated so that it might form in the axial direction at equal intervals in the same shape, if it is a shape which has the said effect, it will not restrict to this.
