Description

Method and apparatus for producing Langue de confectionery

Technical field

[0001] The present invention relates to a method and an apparatus for producing a confectionery obtained by folding a langudosha dough into two pieces.

. In particular, the present invention relates to a manufacturing method and an apparatus capable of mass-producing such a confectionery with a good appearance.

Background art

[0002] In order to make use of the texture and flavor of Langdosha dough, confectionery in which baked Langdosha dough is folded into two is actually sold. This confectionery is a confectionery having a substantially square appearance in which a rectangular Languedocas dough is folded in the middle after firing and then overlaid. Almond slices and the like can also be topped on the surface of the stacked dough.

[0003] At present, when such a confectionery is manufactured, the baked Langdosha dough is folded in half by hand. Langudosha dough has a very short time of about 4 seconds from baking to hardening. The hardened dough has the property of being brittle and fragile. For this reason, if you try to fold by hand within a short time until it hardens, part of the fabric may be missing or it may not be possible to fold it exactly in two. For this reason, the edges of the stacked confections often shift to produce unsightly ones.

[0004] FIG. 10 is an example of a defective two-fold Langue de confectionery product.

In addition, since the fold line F is not in the middle of the dough in the longitudinal direction of the dough, the lengths of the folded pieces Cr, are different, and the pieces Cr, do not overlap exactly.

In the confectionery C ~ shown in Fig. 10 (B), since the fold line F is not perpendicular to the long side of the dough, the shape of the folded pieces Cr C2 ~ is different, and each piece Cr is displaced in the horizontal direction and overlaps exactly. Not.

As described above, when the sheet is folded by hand, the position and angle of the fold line F are not accurate, so that the rate of defective products is high.

Disclosure of the invention

Problems the invention is trying to solve [0005] The present invention has been made in view of the above-described problems, and has as its object to provide an apparatus and a method for correctly folding a langudosha cloth into two.

Means for solving the problem

[0006] The method for producing a langudosha confectionery of the present invention includes: a step of rubbing the langudosha dough into a sheet; a step of firing the rubbed langdosha dough; A method for producing a Langue de confectionery, the method comprising: in the folding step, stopping the rung sheet at a fixed position and in a fixed posture, and setting a leading end of the forming plate to a fold line (fold line) of the rung sheet. The pressing and pressing force S is used to fold the rung sheet into two, and then the folded rung sheet is folded by being conveyed by a conveyor while being sandwiched. Here, a projection is provided at the tip of the forming plate. In addition, the plate and the rung sheet are prevented from being displaced from each other.

[0007] According to the present invention, a projection is provided at the tip portion of the forming plate when the forming plate is folded in two while pressing the tip of the forming plate against the folding line of the rung sheet that is stationary at a fixed position and in a fixed posture. Since the gap between the plate and the rung sheet is prevented, the position and angle of the folding line can be kept constant. For this reason, Langduscha confections with good appearance can be mass-produced.

[0008] The apparatus for producing a Langudoscha confectionery of the present invention is characterized in that:

A confectionery manufacturing apparatus for folding a rung sheet, comprising: positioning means for stopping the rung sheet at a fixed position and in a fixed posture; and folding the stationary rung sheet in two along a fold line (fold line). A folding means, and a pinch-feeding means for feeding the rung sheet folded in half while sandwiching the rung sheet, wherein the bi-fold means has a leading end applied to a fold line of the rung sheet and presses the fold line while pressing the fold line. It has a forming plate for folding the rung sheet in two, and a protrusion for preventing a deviation between the plate and the rung sheet is provided at a tip end of the forming plate.

[0009] In the present invention, the positioning means includes: a charging conveyor inclined downward, a receiving bar extending so as to be connected to a tip of the conveyor, and a stopper disposed downstream of the receiving bar. It is preferable that a forming plate is disposed on the side of the conveyor from the stopper, and is driven in a direction orthogonal to the receiving bar. [0010] When the rung sheet is conveyed by the feeding conveyor inclined downward, the sheet is subjected to inertia force toward the front of the track and gravity corresponding to the inclination. Then, the rung sheet is brought into contact with the stove by these forces, so that the sheet can be stopped at a fixed position and in a fixed posture in a short time.

In addition, by disposing the forming plate at a position separated from the stove surface by a fold length (for example, half of the length of the land sheet) on the conveyor side, the tip of the forming plate can be securely aligned with the fold line of the rung sheet. Can be used.

The invention's effect

[0011] As is clear from the above description, according to the present invention, the position and angle of the fold line of the Langudosya fabric can be made constant and correct. In addition, Langdosha fabric can be folded in two in a short time. Therefore, it is possible to provide an apparatus and a method capable of mass-producing a good-looking Langue Dessert.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, a confectionery manufactured by the confectionery manufacturing apparatus of the present invention will be described.

FIG. 9 is a diagram showing the shape of a confectionery manufactured by the confectionery manufacturing apparatus of the present invention, wherein FIG. 9 (A) is a plan view of a confectionery dough, FIG. 9 (B) is a side view of the completed confectionery, FIG. (C) is a perspective view of the whole confectionery.

The confectionery is produced by baking a sheet of Langudosha dough (Lang sheet). As shown in Fig. 9 (A), the planar shape of the rung sheet D is rectangular, and as an example, the length (length of the long side) of the fabric D is about 80 mm, the width (length of the short piece) is about 40 mm, The thickness is about 2mm.

[0013] This rung sheet D is folded back in two along a folding line F that is a half in the longitudinal direction. Fold line F is perpendicular to the long side of Lang sheet D. When folded, the surface that was in contact with the surface of the baking sheet of the band oven (continuous baking device) of Lang Sheet D is the inside, and the opposite surface is the outside. When the dough is baked in a band oven, the surface in contact with the oven surface has a rough, rough feel. On the other hand, the surface that is not in contact with the surface has a relatively smooth feel, and the outer periphery is baked and has a delicious appearance. Therefore, by folding the rung sheet in half with the side not in contact with the band oven on the outside, the surface that looks delicious Can be on the outside surface of the confectionery.

[0014] The completed confectionery C has a substantially square shape, and the folded pieces Cl and C2 overlap almost exactly as shown in Fig. 9 (B). The outer surface of the dough D (the surface that was not in contact with the band oven) is the outer surface of the confectionery C. The sides of the outer surface of the confectionery C other than the fold line are outlined in baked color.

Next, an apparatus for producing the confectionery C will be described.

First, the overall configuration of the confectionery production line will be described.

FIG. 1 is a block diagram showing the overall configuration of a confectionery production line.

The confectionery production line is located from upstream to downstream (from left to right in the figure), with a rubbing device (rubbing process), a band oven (firing process), and a confectionery device 1 (folding process). The cooling unit 130 is mainly composed of a packaging machine.

In the rubbing device, the langudosha cloth is rubbed into a rectangular sheet shape as shown in FIG. 9 (A). A commonly used device can be used as the sliding device. Then, the rubbed sheet-shaped Langue dougha material is fired in a band oven. The band oven can also use a commonly used apparatus.

[0016] An example of the composition and baking conditions of the Langdosha dough is as follows.

Lower temperature 130 ° C (4 minutes 5 seconds) 130 ° C (2 minutes 35 seconds)

[0018] The dough baked in the band oven is transferred to the confectionery manufacturing apparatus 1 of the present invention. This confectionery manufacturing apparatus includes a positioning means (positioning unit) for stopping the baked dough in a fixed position in a fixed position, a folding means (folding unit) for folding the stationary dough in half, and It has a pinch feeding means (pinch feeding section) 100 for feeding the folded dough while pinching it.

The dough that has been folded and formed is transferred to a cooling conveyor 130, cooled, and then packed by a packaging machine.

Next, the structure of the confectionery manufacturing apparatus 1 according to the embodiment of the present invention will be described in detail.

First, the positioning means 10 will be described.

The positioning means 10 conveys the baked Langdosha cloth (lang sheet) to which the band oven force has been transferred to a fixed position, and stops at the same position in a fixed posture.

FIG. 2 is a side view showing the configuration of the positioning means.

FIG. 3 is a front view of the positioning unit.

As shown in FIG. 2, the surface force of the band oven 13 of the rung sheet D is also transferred to the positioning unit 10 of the confectionery manufacturing device 1 by the transfer device 11. As the transfer device 11, a general device can be used. With this transfer device 11, the rung sheet D is transferred to the positioning section 10 in a state of extending in the longitudinal direction, with the surface in contact with the band oven 13 as the lower side and the unstressed surface as the upper side.

[0021] The positioning section 10 has a charging conveyor 15 shown at substantially the center of the figure, a stopper 35 and a receiving bar 37 shown at the right side of the figure. As shown in FIG. 3, the loading conveyor 15 is a conveyor composed of two parallel rows of endless plastic chains 16A and 16B. As shown in FIG. 2, each plastic chain 16 is wound between an upstream sprocket 17 and a downstream sprocket 19 and circulates clockwise in the figure on an annular orbit. The upstream sprocket 17 is located above the downstream sprocket 19, and each chain 16 is inclined downward from the upstream sprocket 17 toward the downstream sprocket 19. Further, a guide roller 21 is interposed between the two rollers to divide the two rollers into two parts having different inclinations. The slope between the upstream sprocket 17 and the guide roller 21 is relatively gentle, forming a gentle slope 25. ing. In this example, the angle of the gentle slope 25 to the plane is 10 °. Between the guide roller 21 and the downstream sprocket 19 is a steeply inclined portion 27 whose inclination is relatively steep. In this example, the angle of the steeply inclined portion 27 with respect to the plane is 18 °. The upper surface of the chain 16 in the steeply inclined portion 27 is defined as a transfer surface P1.

[0022] A drive gear 29 is interposed between the downstream sprocket 19 and the upstream sprocket 17 of the chain 16 at a portion facing the upstream sprocket 17. When the drive gear 29 is driven by the motor, the plastic chain 16 circulates clockwise in the figure on an annular orbit.

As shown in FIG. 3, side guides 31 are provided on both sides of the plastic chain 16 between the most upstream sprocket 17 and the most downstream sprocket 19. The width between the side guides 31 is 43 mm, which is a dimension having a clearance of about 3 mm on both sides in the width direction of the rung sheet D (about 1.5 mm on each side).

[0024] As shown on the right side of Fig. 2, at a position away from the most downstream portion of the conveyor 15 (the turn portion at the downstream sprocket 19 of the plastic chain 16) on the extension of the steeply inclined portion 27 of the conveyor 15, A stopper 35 is provided. The stopper 35 has an L-shape. One surface (stopper surface) 35a extends at a right angle to the transfer surface P1, and the other surface 35b is fixed to the apparatus main body so as to be movable in the transfer surface P1 direction. I have. That is, the position of the stopper surface 35a can be changed on the transport surface P1.

[0025] A gap W1 is opened between the most downstream portion of the conveyor chain 16 and the stopper surface 35a. The length of the gap W1 with respect to the transport surface P1 is 44 mm in this example. Then, the stopper surface 35a and the four receiving bars 37 are set upright in the direction perpendicular to the stopper surface 35a and in the direction extending on the transport surface P1 so as to be continuous with the steeply inclined portion 27 of the conveyor 15. ! / Puru.

The angle of each part of the conveyor 15, the angle of the receiving bar 37, and the conveyor feed speed are set to appropriate values so that the sent rung sheet D does not stop on the way or bounce off the stopper surface 35a.

FIG. 4 is a diagram showing a configuration of a main portion of the positioning portion and the two-fold portion. FIG. 4 (A) is a plan view, and FIG. 4 (B) is a side view. In these drawings, the transport surface P1 is drawn as being horizontal.

As shown in FIG. 4B, each receiving bar 37 extends on the transport surface P1 of the conveyor 15. As shown in FIG. 4 (A), each bar 37 extends in parallel at equal intervals (in this example, 10 mm), and out of the four receiving bars 37, the length of the outer two receiving bars 37A is longer. The length is shorter than the length of the two inner receiving bars 37B. In this example, the diameter of each receiving bar 37 is 3 mm, the length of each outer receiving bar 37A is 38 mm, and the length of each inner receiving bar 37B is 60 mm. As shown in FIG. 4 (A), the inner receiving bar 37B extends from the stopper surface 35a between the two chains 16A and 16B of the conveyor 15, and the chain 16 and the tip of the inner receiving bar 37B are connected. They overlap on the transport plane P1. On the other hand, the outer receiving bar 37A does not reach the chain 16, and a gap W2 is opened between the tip of the outer receiving bar 37A and the conveyor chain 16. The length of the gap W2 is 6 mm in this example.

An auxiliary side guide 32 extending from one side guide 31 (lower side in FIG. 4A) extends between the downstream sprocket 19 and the stopper 35 of the conveyor 15.

With reference to FIG. 2, the movement of the rung sheet in the positioning section 10 will be described.

The rung sheet D transferred to the positioning section 10 is conveyed from the gentle slope section 25 of the conveyor 15 to the steep slope section 27 in the left direction to the right in the figure, and reaches the downward turn section of the most downstream sprocket 19. . In this turn, as shown in FIG. 4 (A), since the chain 16 and the tip of the inner receiving bar 37B overlap on the force transfer surface P1, the rung sheet D also receives the force on the chain 16 on the receiving bar 37. Can be transferred. Then, the rung sheet D is conveyed until the front end hits the stopper surface 35a of the stopper 35. The conveyor 15 is not present between the turn portion of the conveyor 15 and the stopper surface 35a (gap W1), but even if the front end of the rung sheet D moves onto the receiving bar 37, the rear portion of the sheet D Since it is still on the conveyor 15, a force (inertial force) for sending the rung sheet D forward is acting. Also, due to the inclination of the steeply inclined portion 27, gravity corresponding to the inclination acts on the rung sheet D conveyed through the same. With these forces, the rung sheet D is transferred from the conveyor 15 to the receiving bar 37 until the front end hits the stopper surface 35a.

As described above, the rung sheet D is positioned in the longitudinal direction with the front end abutting on the stopper surface 35a. In addition, the auxiliary sheet guide 32 having a width close to the width of the rung sheet D is positioned in the width direction. Therefore, the rung sheet D is always conveyed to the receiving bar 37 without shifting in the longitudinal direction and the width direction. Further, since the sheet D stops immediately without hitting the stopper surface 35a, it is possible to perform high-speed production without having to wait until the sheet D stops at a fixed position. As an example, the time from when Langsheet D is loaded into the loading conveyor 15 to when it is transported onto the receiving bar 37 is about 2.5-3 seconds.

Next, the folding section 50 will be described with reference to FIGS.

FIG. 5 is a diagram for explaining the folded part.

In the half-folding section 50, the rung sheet D is folded in two while standing on the receiving bar 37. The part 50 includes a forming plate 51 disposed below the receiving bar 37 and upper and lower forming conveyors 70 and 80 disposed above the plate 51. As shown in detail in FIGS. 4 (A) and (B), the forming plate 51 is about half the length of the rung sheet D W3 (in this example, 41 mm) in the direction from the stopper surface 35a toward the conveyor 15. It is located at a distance only and extends to a plane P2 perpendicular to the transport plane P1. Then, it is driven up and down in a plane P2 orthogonal to the transport plane P1.

FIG. 6 is a diagram showing the positional relationship between the shape of the forming plate and the receiving bar, where FIG. 6 (A) is a plan view and FIG. 6 (B) is a front view.

The forming plate 51 is a comb-shaped plate as shown in FIG. 6 (B). In this example, the length of the plate 51 is 130 mm, and the width is 40 mm, which is almost equal to the width of the rung sheet D. Two slits 53 are formed at the distal end of the plate 51 so that the distal force of the plate 51 is also cut in the length direction. The width of each slit 53 is 4.5 mm in this example, which is slightly larger than the diameter of the receiving bar 37. The interval between the slits 53 is 10 mm. The slit 53 divides the plate tip into three pieces, left and right pieces 51a and 51b and a center piece 51c. Projections 55 are provided upright on the tip surfaces of the pieces 51a, 51b, 51c. Each projection 55 has a columnar shape, and the tip surface is flat. The diameter of the projection 55 is 1 mm and the length is 2 mm. Spacing between projections 55 [Up to 15mm.

As shown in FIG. 6 (A), when viewed from a direction orthogonal to the transport surface P1, the forming plate 51 is provided with a gap W2 between the tip of the outer short receiving bar 37A and the turn portion of the chain 16. It is located in. In the gap W2, the forming plate 51 crosses the lower side of the inner receiving bar 37B in the width direction. The central piece 51c of the forming plate 51 is B, each slit 53 is located directly below the inner receiving bar 37B. With such an arrangement, when the forming plate 51 is moved upward on the plane P2 perpendicular to the conveying plane P1 in the gap W2, the left and right pieces 51a and 5 lb of the plate pass through the gap W2. Then, the inner receiving bar 37B enters into each slit 53, and the force between the center piece 51c and the inner receiving bar 37B also passes through the gap W2. Thereby, the forming plate 51 moves upward beyond the receiving bar 37.

As shown in FIG. 5, the forming plate 51 has a projection 55 at the tip located at a lower position where the projection 55 is located below the transfer surface P 1, and an upper surface protruding from the receiving bar 37 into a surface P 2 orthogonal to the transfer surface P 1. The position is moved up and down by the lifting mechanism 60.

The elevating mechanism 60 is provided at the lower end of the forming plate 51. By this elevating mechanism 60, the forming plate 51 is moved up and down in the same direction by a linear guide 61 extending in a direction perpendicular to the transport plane P1. The elevating mechanism 60 has a turnbuckle 63 to which the lower end of the forming plate 51 is connected to one end 63 a, and a servomotor 67 connected to the other end 63 b of the turnbuckle 63 via a crank 65. The turn buckle 63 can change the length between the connecting position 63a with the forming plate 51 and the connecting position 63b with the crank 65, and adjusts the position (height) of the forming plate 51. When the motor 67 is driven, the forming plate 51 moves along the linear guide 61 via the crank 65 and the turnbuckle 63.

In this example, the moving distance of the forming plate 51 is 60 mm, and the position moved to the highest position is a position 60 mm above the transport surface P1.

A proximity switch 69 is provided below the turnbuckle 63. The switch 69 detects the movement of the turnbuckle 63 and controls the position of the forming plate 51.

After the rung sheet D is conveyed from the charging conveyor 15 onto the receiving bar 37 and stops, the forming plate 51 is raised by the lifting mechanism 60. At this time, as described above, the forming plate 51 passes through the inner receiving bar 37B at the portion of the slit 53 and rises. Then, the stationary rung sheet D is lifted on the end surface force receiving bar 37 of the forming plate 51. Looking at the force in the direction perpendicular to the conveying surface P1, the forming plate 51 is located at a position W3 that is half the length of the rung sheet D from the stopper surface 35a. Is lifted by the forming plate 51. Lang sheet D In contact with the band oven 11! / ヽ The face is on the top! /, So the face is on the outside! / ヽ

[0038] At this point, the rung sheet D is shortly after firing, and is then folded in two along the forming plate 51, which is still soft. The width of the forming plate 51 is almost the same as the width of the rung sheet D. The tip of the forming plate 51 is divided into three pieces with two slits 53 interposed as described above.1 The width of the slit 53 is possible. Because it is as narrow as possible, the rung sheet D can be lifted over almost the entire width direction. Therefore, the fold line of the rung sheet D can be straightened. Further, the projections 55 formed on the distal end surface of each piece of the forming plate 51 can hold the rung D on the distal end surface of the plate 51 without slipping. The protrusion 55 does not penetrate deep into the rung sheet D, but lifts the rung sheet D with the tip slightly immersed in the surface of the rung sheet, so that the sheet D is not easily slipped from the protrusion 55. For this reason, the forming plate 51 can surely lift the middle part of the sheet D. After the rung sheet D is removed from the forming plate 51, almost no trace of the projection 55 remains on the sheet D.

Next, the upper and lower forming conveyors 70 and 80 will be described with reference to FIG.

The upper and lower molding conveyors 70 and 80 are arranged above the conveying surface P1, and the upper molding conveyor 70 is arranged on one side (the left side in the figure) of the surface P2 orthogonal to the conveying surface P1. 80 is located on the other side (right side in the figure) of the same plane P2. The upper and lower forming conveyors 70 and 80 convey the rung sheet D folded in two along the forming plate 51 to the next sandwiching feed unit 100 while removing the forming plate 51 force. The rung sheet D that has been folded in two is sandwiched from both sides by the upper and lower forming conveyors 70 and 80, and is conveyed with the fold first in the same direction as the moving direction of the forming plate 51, that is, in the direction orthogonal to the conveying surface P1. Is done.

[0040] The upper forming conveyor 70 is a sheet conveyor. The sheet 71 is wound between the upstream roller 73 and the downstream roller 75, and circulates in a circular orbit in a counterclockwise direction in the drawing. A press roller 77 is disposed between the upstream roller 73 and the downstream roller 75.

The lower forming conveyor 80 is also a sheet conveyor, and the sheet 81 is wound between the upstream roller 83 and the downstream roller 85 (see FIG. 7) and circulates on an annular track in the counterclockwise direction in the figure. . In addition, between the upstream roller 81 and the downstream roller 85 of the lower forming conveyor 80, An idler 87 is disposed. A press roller 89 is disposed between the upstream roller 81 and the guide roller 87.

The moving speed of each conveyor is equal.

[0041] The sheet 71 of the upper forming conveyor 70 is directed toward the downstream roller 75 from the upstream roller 73, and the sheet 81 of the lower forming conveyor 80 is directed toward the guide roller 87 from the upstream roller 83, and is orthogonal to the transport surface P1. Are arranged symmetrically with respect to the plane P2. The interval between the upstream rollers 73 and 83 is wider than the interval between the pressing rollers 77 and 89. The interval between the downstream roller 75 and the guide roller 87 is equal to the interval between the pressing rollers 77 and 89. By arranging the rollers in this way, the space between the sheets 71 and 81 of the upper and lower forming conveyors 70 and 80 is narrowed by the force between the upstream rollers 73 and 83 and the force between the press rollers 77 and 89. The distance between the rollers 77 and 89 is constant between the downstream rollers 75 and the guide rollers 87. This interval is 9 mm in this example, which is about twice the thickness of the rung sheet D plus the thickness of the forming plate 51. That is, in this portion, the rung sheet D that has been folded is only held between the two sheets by contacting the sheets 71 and 81 with both-side forces.

As shown in FIG. 5, the forming plate 51 rises between the sheets 71 and 81 of the upper and lower forming conveyors 70 and 80 to an upper position where the tip thereof slightly exceeds the space between the pressing rollers 77 and 89. When the forming plate 51 is raised to the upper position, the rung sheet D folded along the end of the forming plate 51 is moved to both sides at 77 and 89 by the pressing rollers via the sheets 71 and 81 of the respective conveyors 70 and 80. Between. At this time, as described above, the distance between the sheets 71 and 81 is such that the thickness of the rung sheet D folded in half along the thickness of the forming plate 51 is approximately equal to the thickness of the rung sheet D. Is not pressed on both sides. Thereafter, the forming plate 51 is moved downward. The folded rung sheet D is held between the sheets 71 and 81 by friction.

A guide roller 79 is interposed between the downstream roller 75 and the upstream roller 73 of the upper molding conveyor 70 in a portion facing the upper roller 73. The guide roller 79 adjusts the tension of the sheet 71 of the conveyor 70.

Next, the sandwiching feed unit 100 will be described with reference to FIG.

FIG. 7 is a side view showing the sandwiching feed section. The pinch feeding section 100 has a holding conveyor 110 and a lower forming conveyor 80. The two-folded rung sheet D is sandwiched between both sides by the holding conveyor 110 and the lower forming conveyor 80, and is conveyed from the half-folded portion 50 to the right in the left direction as shown in the figure, with the fold first. As a result, the folded rung sheet D is sandwiched between both sides, and the folded pieces are overlapped.

The press conveyor 110 is a sheet conveyor, and the sheet 111 is wound between the upstream roller 113 and the downstream roller 115 and circulates counterclockwise in the drawing. The sheet 111 is pressed downward by a pressing plate 117 between the upstream roller 113 and the downstream roller 115. The holding plate 117 extends over substantially the entire length between the upstream roller 113 and the downstream roller 115. The upstream end 117a and the downstream end 117b of the holding plate 117 are curved upward.

The lower forming conveyor 80 is also a sheet conveyor as described above, and the sheet 81 is wound between the upstream roller 83 and the downstream roller 85 and circulates clockwise in the drawing.

The moving speed of each conveyor is equal.

The folded rung sheet D is placed on a sheet 81 extending substantially horizontally from the guide roller 87 of the lower forming conveyor 80 to the downstream roller 85. Then, the rung sheet D is pushed downward from above by a sheet 111 which is directed toward the downstream P-la 115 from the upstream P-la 113 force of the push-pull = 3, and the two sheets 81, 111 are pushed downward. And transported.

More specifically, the rung sheet D that has passed between the downstream roller 75 of the upper forming conveyor 70 and the guide roller 87 of the lower forming conveyor 80 of the half-folding section 50 is placed on the sheet 81 of the lower forming conveyor 80. It moves to the pinch feeding section 100.

At this time, since the folded-down rung sheet D has already begun to solidify, it is necessary to shift from the inclined surface P2 to a horizontal surface (on the sheet 81) while keeping the folded-down plate-like state. Further, on the sheet 81 along the guide roller 87, the rung sheet D is completely sandwiched between the sheet 71 of the upper forming conveyor 70 and the sheet 111 of the presser conveyor 110, and slides down on the sheet 81 because it is in a state. It is possible.

[0048] For this reason, the diameter of the guide roller 87 is made as large as possible so as to smoothly transition from the inclined portion to the horizontal portion. Further, the distance between the guide roller 87 and the upstream roller 113 of the upper forming conveyor 110 is widened, and the space between the sheets 81, 111 is narrowed by the pressing plate 117 in the upstream direction. [0049] With such a configuration, when the front end of the two-folded rung sheet D protrudes from between the rollers 75 and 87, the sheet 111 of the upper forming conveyor 110 does not contact the same end, When the rung sheet D is directed in the horizontal direction along the guide roller 87, the end is brought into contact with the sheet 111 so as to be bent.

The lower surface of the rung sheet D is conveyed on one lower forming conveyor 80. The upper surface is conveyed by the upper forming conveyor 70 and the pressing conveyor 110. Therefore, the distance between the downstream roller 75 of the upper molding conveyor 70 and the upstream roller 113 of the presser conveyor 110 is made as small as possible so that the upper surface of the rung sheet D can be smoothly conveyed.

The rung sheet D is pushed down by the pressing plate 117 on the upper surface while being transported on the sheet 81, and the sheet 111 of the presser conveyer 110 is abutted. In the portion where the holding plate 117 is arranged, the distance between the sheet 111 of the holding conveyor 110 and the sheet 81 of the lower forming conveyor 80 is 7 mm. This interval is slightly narrower than the interval between the sheets 71 and 81 in the two-folded section 50. For this reason, the two-sided rung sheet D is held down by the sheets 71 and 81 with the double-sided force. In other words, the double-sided force of the rung sheet D is also suppressed, and the inner surface of the rung sheet D is surely brought into close contact.

[0052] The time required for the rung sheet D to be folded from the stationary state on the receiving bar 37 of the half-folding section 50 to being formed into two pieces (until being carried out from the pinch feeding section 100) is about 1.2 seconds. Is

A guide roller 119 is disposed at a portion of the pressing conveyor 110 facing the downstream roller 115 to the upstream roller 113. The guide roller 119 adjusts the tension of the sheet 111 of the conveyor 110.

A guide roller 91 is disposed at a portion of the lower forming conveyor 80 which is directed from the downstream roller 85 to the upstream roller 83. The guide roller 91 adjusts the tension of the sheet 81 of the conveyor 80.

The downstream roller 85 of the lower forming conveyor 80 is fixed to a gear 86 that rotates on a concentric circle. The gear 86 meshes with a drive gear 122 fixed to an output shaft of the motor 121 via a transmission gear 123. A gear 86 to which the downstream roller 85 is fixed is in mesh with a gear 116 that rotates concentrically with the downstream roller 115 of the presser conveyor 110. When the drive gear 122 of the motor 121 rotates clockwise in the figure, the gear 86 rotates clockwise in the figure via the transmission gear 123. Thus, the downstream roller 85 fixed to the gear 86 rotates clockwise in the drawing, and the lower forming conveyor 80 circulates clockwise in the drawing. When the gear 86 rotates clockwise in the figure, the gear 116 meshing with the gear 86 rotates counterclockwise in the figure. Then, the downstream roller 115 of the presser conveyor 110 fixed to the gear 86 rotates counterclockwise in the drawing. Thus, the presser conveyor 110 circulates in the counterclockwise direction in the drawing.

A gear 125 is arranged between the upstream roller 113 of the holding conveyor 110 and the downstream roller 75 of the upper forming conveyor 70. The gear to which the upstream roller 113 of the holding conveyor 110 is fixed and the gear to which the downstream roller 75 of the upper forming conveyor 70 are fixed via the gear 125. When the presser conveyor 110 circulates in the counterclockwise direction in the figure, the gear 125 is driven by the upstream roller 113 of the presser conveyor 110, and rotates in the opposite direction to the presser conveyor 110, ie, clockwise. When the gear 125 rotates, the downstream roller 75 of the upper forming conveyor 70 circulates in a direction opposite to the gear 125, that is, in a counterclockwise direction.

A cooling unit (cooling conveyor) 130 is arranged downstream of the sandwiching feed unit 100.

FIG. 8 is a side view showing the cooling conveyor.

The cooling unit conveyor 130 cools and aligns the formed two-fold rung sheet D while conveying it. The conveyor 130 is a sheet conveyor, and the sheet 131 is wound between an upstream roller 133 and a downstream roller 135 and circulates in a circular orbit in a clockwise direction in the drawing. The rung sheet D is conveyed from the upstream roller 133 to the downstream roller 135 on the force sheet 131 from left to right in the drawing.

[0058] At a portion between the upstream roller 133 and the downstream roller 135, guides 139 are provided on both sides of the sheet 131. At the upstream end of the guide 139, a chute plate 141 extending to the sandwiching feed portion 100 is provided. The chute plate 141 is inclined slightly downward from the sheet 81 of the lower forming conveyor 80 to the sheet 131 of the cooling conveyor 130. The rung sheet D is sent out from the pinch feeding section 100 onto the cooling conveyor 130 through the chute plate 141.

[0059] Above the portion between the upstream roller 133 and the downstream roller 135, an alignment device 143 is disposed. The rung sheet D is between the upstream roller 133 and the downstream roller 135. Are guided straight by the guide 139. Also, a predetermined space can be opened in the transport direction by the alignment device 143.

[0060] A guide roller 137 is disposed at a portion where the downstream roller 135 faces the upstream roller 133 to adjust the tension of the sheet 131. Further, the downstream roller 135 is connected to the drive roller 143, and is driven by the drive roller 143 to rotate clockwise in the drawing.

[0061] The langue de confectionery cooled and aligned by the cooling conveyor 130 is conveyed to a packing machine (not shown) arranged downstream of the cooling conveyor 130, and is individually packed by the same machine.

[0062] By providing a plurality of sets (for example, 10 sets) of such a confectionery manufacturing apparatus 1 as one apparatus, Langduscha confectionery C can be mass-produced at high speed (an apparatus having 10 sets of the confectionery manufacturing apparatus 1!). /, 24,000 pieces Z time).
