In the above-described conventional method for manufacturing a confectionery bread, the thick bread W is used as described above, and the filling is supplied in an inserted state between the upper bread loaf portion and the lower bread loaf portion formed by the cutting. Therefore, when the filling is supplied, it is necessary to temporarily lift the upper bread, and the amount of the filling cannot be increased, and the filling is supplied in the form of a wide plate. There are inconveniences such as mounting in a state and supply of solid filling is difficult. Moreover, the type of bread cannot be different between the upper bread portion and the lower bread portion of the sweet bread.
The present invention addresses these inconveniences, and the problem is that one sheet-like piece to be conveyed is overlaid with another sheet-like piece, and two sheet-like pieces are used. It aims at providing the stacking apparatus of the sheet-like piece which makes it possible to match | combine pieces reliably.

In order to achieve the above object, the present invention forms a first conveyance line and a second conveyance line, conveys one sheet-like piece at each conveyance line, and is conveyed by the second conveyance line. In the sheet stacking device for stacking one sheet-shaped piece on the sheet-shaped piece for each sheet transported by the first transport line in the middle of transporting the first transport line,
When the leading end side of the second conveying line is viewed from above, the conveying direction of the sheet-like piece of the second conveying line is the same as the conveying direction of the sheet-like piece of the first conveying line, and the side is viewed from the side. The first conveying line is disposed at a specific height position in the middle of the first conveying line so as to be inclined downward with respect to the conveying direction of the sheet-like piece of the first conveying line. A sensor that detects that the sheet-like piece of the conveying line has reached a predetermined position with respect to the tip position of the second conveying line, and a sheet-like piece that is provided in the second conveying line and reaches the leading end are stopped. At the same time, the stop is released at a predetermined timing based on the detection of the sensor so that the leading edge of the sheet-like piece from the second conveying line is aligned with the leading edge of the sheet-like piece conveyed on the first conveying line. On top stopper It was configured with.

In order to achieve the above object, in the sheet-like piece stacking apparatus of the present invention, first, a first conveyance line and a second conveyance line are formed, and one sheet-like piece is conveyed by each conveyance line. Then, one sheet-like piece conveyed by the second conveyance line is placed on each sheet-like piece conveyed by the first conveyance line in the middle of conveyance of the first conveyance line.
Therefore, for example, in a sweet bun that has a filling between two sheet-shaped bread pieces, cut the ear-shaped sheet-like bread pieces on the upper side of the ear-like sheet-like bread portion in a state where one end is attached and is attached vertically The conventional process of lifting from the side and opening for supplying the filling is not necessary, and therefore the conveying speed of the above-mentioned ear-like sheet-shaped bread pieces to which the filling is supplied is such that the sheet-like bread-like portion of the ear-like sheet bread in the vertically arranged state (Sheet bread slices with ears) will be increased compared to the conventional processing, and the filling supply space is secured wider than before, increasing the supply amount of filling, plate-like, and lamination And solidification can be achieved. In addition, the type and thickness dimensions of the top and bottom sheet-like bread pieces can be freely selected. This means that the type and overall thickness dimensions can be easily and freely changed between the two layers. None, it becomes possible to have various varieties of food texture as well as diversification of the filling.
Further, according to the present invention, the upper stopper provided in the second transport line is released from the stop by releasing the upper stopper provided in the second transport line at a predetermined timing based on the detection of the sensor provided in the first transport line. When the upper sheet-like piece is lowered, the timing with the lower sheet-like piece is adjusted so that the sheet-like piece is lowered and overlapped with the lower sheet-like piece conveyed on the first conveying line. Therefore, it is possible to reliably align the tips of the upper and lower sheet-like pieces.

  If necessary, it is effective to provide the upper stopper in front of the tip of the second transport line and provide a space between the tip and the upper stopper. The leading edge of the upper sheet-like piece descends from the state where it is exposed and stopped in the space between the leading edge of the second conveying line and the upper stopper. Since the lowering distance can be shortened, the tips of the upper and lower sheet-like pieces can be more accurately aligned with each other.

  Further, if necessary, when the sheet-like pieces are overlapped with the first conveyance line, the sheet-like pieces are engaged with the leading edge of the first conveying line in front of the leading edge of the second conveying line. A lower stopper for temporarily stopping is provided. Since the lower sheet-like piece is stopped by the lower stopper and the sheet-like piece from the upper side is awaited, the top ends of the upper and lower sheet-like pieces can be aligned more accurately at this point Become.

  Further, one or a plurality of pressing rollers for pressing the sheet-like piece are provided behind the upper stopper as necessary. When the upper stopper stops and moves, etc., or when the sheet-like piece descends, the sheet-like piece is held by one or more pressing rollers, so the tip of the sheet-like piece is raised or lowered. Therefore, alignment with the tip of the lower sheet-shaped piece is performed more reliably.

  Furthermore, it is set as the structure which provided the overlapping position adjustment mechanism which adjusts again the overlapping position of the two said sheet-like piece superimposed as needed. Even if there is a slight deviation between the upper and lower sheet-like pieces, this is corrected and the upper and lower sheet-like pieces are surely matched.

In this case, the overlapping position adjusting mechanism is moved from the lower side to the moving path of the overlapped sheet-like pieces of the first conveyance line, and a plurality of fingers holding the sheet-like pieces from the front and back, and the fingers A finger advancing / retreating part that advances after moving to the moving path and maintains after a predetermined time, and a finger that moves all or part of the fingers that have advanced to the moving path in the front-rear direction to grip the sheet-like piece and retract after holding It is effective to have a holding drive unit. Since it is held and adjusted by a finger, the mechanism becomes easy.
In addition, it is effective to form the fingers in a substantially L-shaped cross section so as to press the four corners of the sheet-like piece and to provide a pair of front and rear. Since the finger presses the four corners of the sheet-like piece, the left and right and front-and-rear pressing is ensured, and the upper and lower sheet-like pieces are more reliably matched.
In the present specification, the front means the same as the downstream in the transport direction, and the rear means the same as the upstream.

  According to the sheet-like piece stacking apparatus of the present invention, first, the first conveyance line and the second conveyance line are formed, and one sheet-like piece is conveyed by each conveyance line, and the second conveyance is performed. Since one sheet-like piece conveyed by the line is placed on one sheet-like piece conveyed by the first conveyance line in the middle of conveyance of the first conveyance line, for example, the sheet-like piece is In a confectionery bread in which a filling is present between two sheet-shaped bread pieces as a sheet-shaped bread piece, the upper ear-shaped sheet shape of the ear-like sheet-like bread portion in a state of being arranged vertically with one end attached The conventional process of lifting the bread pieces from the cut side and opening them for supplying the filling is unnecessary, and therefore the conveying speed of the sheet-like bread pieces with ears supplied with the filling is arranged vertically. Increased compared to the conventional process of separating the sheet-like bread pieces with ears (sheet-like bread pieces with ears) in a separated state, and the filling is supplied in a wide plate shape and placed in a laminated state of a plurality of layers in particular. In addition, the filling supply space is ensured wider than before, and the filling supply amount can be increased and solidification can be achieved. In addition, the type and thickness dimensions of the top and bottom sheet-like bread pieces can be freely selected. This means that the type and overall thickness dimensions can be easily and freely changed between the two layers. None, it becomes possible to have various varieties of food texture as well as diversification of the filling.

  Also, based on the detection of the sensor provided in the first conveying line, the upper stopper provided in the second conveying line is released from stopping at a predetermined timing to lower the upper sheet-like piece from the second conveying line. Since it is overlapped with the lower sheet-like piece conveyed by the first conveying line, the timing with the lower sheet-like piece can be adjusted when the upper sheet-like piece is lowered, so the upper and lower sheets There is an effect that the tips of the pieces can be reliably aligned with each other.

  Hereinafter, a sheet-like piece stacking apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In particular, in the guide rail 82, the portion 82 a corresponding to the upstream sprocket 80 is at the stage where the upper surface of the lower die 19 is as early as possible when the lower die 19 receives the confectionery bread intermediate product from the delivery conveyance unit 17. It is formed in another track that is not a circular track along the sprocket 80 so as to be horizontal. Specifically, as shown in FIG. 11 (a), the lower punching die 19 that has been transported with the guide rail 82 turned upside down at the portion corresponding to the upstream sprocket 80 is the Soon after the center of the sprocket 80 passes and the reversal starts so that the upper surface is on the top, the center point (O1) of the circular orbit drawn by the sprocket 80 is declined 45 degrees obliquely downward. The center point (O2) has a diameter (R2) longer than the radius (R1) of the circular orbit of the projection 81 centered on the center point (O1) of the sprocket 80 and is outward from the center point of the sprocket 80. It forms as a trajectory when a circle is drawn up to an angle of 90 degrees. Accordingly, the lower punching die 19 can be in a posture in which it is easy to receive the confectionery bread intermediate product from the delivery conveyance unit 17 so that the reception is reliably performed.
In addition, the guide rail 82 is inclined at the portion corresponding to the sprocket 80 on the downstream side thereof so that the upper surface of the lower die 19 is inverted to the lowest possible stage when the lower die 19 is handed over the pastry bread. Therefore, it is effective to have another track that is not a circular track along the sprocket 80. Specifically, as shown in FIG. 11 (b), the lower punching die 19 that has been transported horizontally with the upper surface of the guide rail 82 at the site corresponding to the downstream sprocket 80 is shown in FIG. Even after passing through the center of the sprocket 80, the trajectory is as straight as possible, and then formed as a circular trajectory along a circular trajectory drawn by the sprocket 80. As a result, it is possible to avoid that the upper surface of the lower die 19 is horizontal or steeply inclined as late as possible, so that the lower die 19 can be taken out of the confectionery bread to the downstream conveyor conveyor 43. The posture can be easily delivered, and this delivery is facilitated.
In addition to the portions corresponding to both the upstream and downstream sprockets 80, the guide rail 82 has an endless transport chain 18 from which the lower die 19 returns from the downstream sprocket 80 to the upstream sprocket 80. It is provided adjacent to almost the entire length of the path of the underlaying portion 18b, and the return conveyance of the lower die 19 is stabilized. And it does not exist in the path | route of the endless conveyance chain which pinches | interposes and presses pastry bread intermediate goods w2 with a pair of upper and lower cutting dies 19,21.

  Details of each lower die 19 are as follows. As shown in FIGS. 14 to 18, the lower punching die includes a die main body portion 25, a rectangular frame-shaped main portion 26 that is provided in the die main body portion 25 and crimps the periphery of the bread, and the die main body portion 25. An extruding body 27 that can be moved to two positions, i.e., an immersion position that is provided in the mold main part 26, and an extruding position that protrudes from the mold main part 26 and extrudes the bread bread that has been pressed by the mold main part 26; And a spring 31 that constantly urges the extruded body 27 to the immersive position.

  That is, as shown in FIG. 14, it has a mold body 25 and a mold main part 26 fixed to the upper surface of the mold body 25 so as to be replaceable. A guide concave portion 25a and a longitudinal guide hole 26a are formed at the central portion of the mold main body 25 at the central portion of the mold main body 26, and a diametrical deep groove shown in FIG. 16 is formed in the guide hole 26a. The extruded body 27 on which 27a is formed is loosely fitted, and two vertical holes 25b and 25b are formed in the thick part at the lower part of the mold body 25 to slide in each of the vertical holes 25b and 25b. The rods 28, 28 are inserted, the upper ends of the sliding rods 28 are screwed onto the lower surface of the extruded body 27, and the lower ends of the sliding rods 28, 28 are connected by a connecting member 29. In addition, a roller 30 is provided on the lower surface side, and a compression spring 31 is extrapolated to each sliding rod 28 portion located between the connecting member 29 and the lower surface of the mold main body 25.

  On the other hand, as shown in FIG. 16, the mold main part 26 is formed into a rectangular body, and the upper surface thereof has a relatively thin cut surface portion 26b positioned on the outer peripheral edge, and the cut surface portion 26b has an inner side along the same. The pressing surface portion 26c that forms a relatively shallow recessed surface, and the rectangular recessed portion 26d that is positioned relatively deep inside the pressing surface portion 26c are formed. The recess 26d communicates with the guide hole 26a so that the extruded body 27 can be displaced vertically.

  In addition, as shown in FIGS. 2, 9, and 10, the present apparatus is provided with an extruded body moving mechanism 90 that moves the extruded body after completion of crimping of the bread. The pusher moving mechanism 90 engages with the roller 30 as a cam follower provided in each pusher 27 and the roller 30 of the pusher 27 provided at the end of conveyance of the conveying means, and presses the roller 30. And a cam plate 38 for moving the extruded body 27 to the pushing position.

  That is, a vertical cam plate 38 is provided between the sprockets 80 on the downstream side of the transport chains 18, 18. The cam plate 38 has a substantially tear shape when viewed from the side, and has a head shape. The outer peripheral edge of the head engages with the roller 30 of the lower punching die 19 to displace the extruded body 27 up and down with respect to the die body 25. Thus, the rollers are limited to a section from the time when the lower punching die 19 reaches the downstream position p2 of the upper portion 18a of each conveying chain 18, 18 to the time when it passes the arcuate portion 18 of each conveying chain 18, 18. 30 is engaged with the outer peripheral edge of the head of the cam plate 38 and pressed to move the extruded body 27 to the pushing position, and the state where the push-up body 27 is pushed upward toward the upper surface side of the mold main part 26 is maintained.

On the other hand, as shown in FIGS. 2, 9 and 12, the guide support 20 can be reciprocated in the front-rear direction by the reciprocating drive mechanism 100 via a front-rear guide track 32 fixed to the upper part of the stationary table 23. In addition, power drive cylinder devices 33 and 34 for individually moving the upper punching die 21 and the brand mark 22 up and down are installed at the front and rear portions of the guide support 20.
In the present embodiment, two upper punches 21 and branding marks 22 are provided on one guide support 20 in parallel in the width direction.

  By the way, the upper die 21 is configured as follows, that is, as shown in FIGS. 9, 14, and 18, a die main body portion 35 coupled and fixed to the output portion of the power drive cylinder device 33. And a mold main portion 36 fixed to the lower surface of the lower die 19 so as to be replaceable. The mold main portion 36 is formed into a rectangular body in the same manner as the mold main portion 26 of the lower lower die 19. Is symmetrical with the shape of the upper surface of the mold main part 26. Thus, as shown in FIG. 14, the lower surface of the mold main part 36 has a cut surface portion 36a located at the outer peripheral edge thereof, and a press forming a relatively shallow concave surface located along the inner side of the cut surface portion 36a. The surface portion 36b and the recessed portion 36c formed relatively deep inside the pressing surface portion 36b and having a square shape are provided.

On the other hand, the stamp 22 has the marking body 37 coupled and fixed to the output portion of the power drive cylinder device 34 and a heater (not shown) installed inside the marking body 34. A mark portion heated by a heater is formed.
Further, along the track of the upper end portion 18a and the lower end portion 18b of the endless transport chain 18, the lower punching die 19 connected to the endless transport chain 18, particularly around the outer surface of the mold main body 25. A lower punching rail 91 that slides by placing an outer side protruding end 25c formed in a laterally convex shape is parallel to the upper portion 18a and the lower portion 18b of the endless conveying chain 18, respectively. Provided (see FIGS. 10 and 14). As a result, the conveyance of the lower die 19 is further stabilized, and at the upper portion 18a, the upper die 21 is lowered to the lower die 19 to sandwich and press the pastry bread intermediate product w2, An even stronger force can be applied.

  The reciprocating drive mechanism 100 of the guide support 20 is composed of a crank mechanism 101 as shown in FIG. The crank mechanism 101 is provided in the apparatus main body and has a drive motor 103 having a rotation shaft 102 having an axis orthogonal to the moving direction of the guide support 20 and a drive motor 103 provided coaxially with the rotation shaft 102 of the drive motor 103. A disk 104 rotated by a motor 103 and a link 105 having one end pivotally supported by the guide support 20 and the other end pivotally supported at a position eccentric with respect to the axis of the disk 104 are configured. .

  Further, as shown in FIG. 9, a first interference means 39 is provided in the vicinity of the downstream end portion of the upper portion 18a of each conveying chain 18, 18, and the interference means 39 is as shown in FIG. The main body member 40 is fixed to the stationary table 23, and a pair of left and right downward projecting members 41a and 41b fixed thereto. At this time, the pair of downward projecting members 41a and 41b are extended forward and downward so as to be positioned in the vicinity of the left and right outer sides of the track of the lower punching die 19, and the height position and the lateral distance L1 can be changed and adjusted. It has been.

  And the 2nd interference means 42 is being fixed to the stationary base 23 in the lower half range location of the circular-arc-shaped site | part 18c of each conveyance chain 18 and 18. FIG. Similar to the first interference means 39, the second interference means 42 includes a main body member 42a fixed to the lower portion of the stationary table 23, and a pair of left and right upwards projecting forward from the left and right locations of the main body member 42a. The pair of left and right upward projecting members 42b are extended forward and upward so as to be located in the vicinity of the left and right outer sides of the track of the lower punching die 19, as well as the height position and the left and right sides. The direction distance can be changed and adjusted.

  Further, on the front side of the food punching die device 16, a take-out conveyor 43 for taking out the confectionery bread w3 is extended from the vicinity of the front end of the arc-shaped portions 18c, 18c of the conveyor chains 18, 18 to the front, and the conveyor chains 18, 18 are also extended. The take-out conveyer 44 of the bread lobe w4 extends from the lower side of the arc-shaped portions 18c, 18c to the side.

Therefore, for example, when the confectionery bread is manufactured by this confectionery bread manufacturing apparatus, the following process is performed. This will be described with reference to the flowchart shown in FIG.
The filling F is stored in the tanks 10 of the filling supply devices 8a, 8b, 9a, and 9b, and the bread-like bread bread w for three servings is supplied to the bread slice sending devices 1A and 1B. In addition, when the filling F and the stick-shaped bread w are consumed, it supplements suitably.
In this state, the respective parts are put into an operating state, whereby the slicer 2 slices the bar-shaped bread w into the bread slice sending devices 1A and 1B to form a sheet-shaped bread piece w1 with ears of an appropriate thickness. And the 2nd conveyance lines 4a, 4b, 5a, 5b start a continuous feed movement. On each of the first and second transport lines 4a, 4b, 5a, 5b, the feeding mechanism 3 of each bread slice sending device 1A, 1B is a sheet-shaped bread piece w1 with ears formed by a slicer first. Each one is sent out and placed in sequence.

  One sheet-like bread loaf w1 with ears placed on the first conveying lines 4a and 4b sequentially reaches the filling supply position, but one sheet bread loaf w1 with ears reaches this filling supply position. Then, the pumps 11 of the filling supply devices 8a, 8b, 9a, 9b are operated, and the filling F in the tank 10 is placed on the upper surface of the single sheet-like bread loaf w1 on the first conveying line, such as cream or jam. The filling F is supplied in a predetermined amount. This supply is performed for each sheet-like bread loaf w1 with ears placed on the first transport lines 4a and 4b. At this time, at least one of the filling supply devices 8a, 8b, 9a, and 9b is operated for each of the first transport lines 4a and 4b, respectively, 8a and 9a, 8b, and 9b. In addition, when two types of filling are to be supplied for each sheet-like bread piece w1 with ears, two fillings of 8a and 9a, 8b and 9b are supplied for each of the first transport lines 4a and 4b. Activate the device.

  In this way, the sheet-like bread pieces w1 with ears supplied with the filling F are sequentially transported to the positions of the bread stacking devices 13 and 13 by the movement of the first transport lines 4a and 4b.

  In one of the operations of the first transport lines 4a and 4b, the second transport lines 5a and 5b transport the sheet-like bread pieces w1 with the ears placed thereon, whereby each of the sheet-like bread pieces with ears is provided. As described above, w1 reaches the tips of the second transport lines 5a and 5b arranged at specific height positions above the first transport lines 4a and 4b.

  In this transporting process, where there is a right-angle line that is bent at a right angle in the second transport lines 5a and 5b and changes the transport direction of the bread into a right angle, as shown in FIGS. 3 and 4, the actuator 57 of the direction changing mechanism 50 is provided. Actuates to move the rod 53 forward and backward. When the rod 53 advances, the rod 53 protrudes from the upper end of the roller 52 and pushes the bread piece w1 in a direction perpendicular to the traveling direction of the roller conveyor 51. As a result, the bread pieces w1 are delivered to the downstream conveyors whose traveling directions are perpendicular to each other, and the direction is changed. In this case, the rod 53 moves with its trajectory defined by the guide rail 55, but is retracted below the upper end of the roller 51 on the extrusion end side by the guide rail 55. Therefore, the bread piece w1 can be pushed sufficiently without interfering with the downstream conveyor, and the direction change is performed by reliably delivering it. Further, since the rod 53 is provided in a plurality of comb teeth on the holding body 54, it can be pushed over the entire length of the rear end of the bread piece w1 and can be pushed reliably without breaking the posture. Further, since the cylinder 57b of the actuator 57 can be rotated so as to follow the trajectory of the rod 53, the operation is smoothly performed.

  By the way, in the bread laying apparatus 13, 13, the sensor 14 operates as described above, and on the sheet-like bread loaf w1 with the ears being carried on the first conveying lines 4a, 4b based on this detection signal. Since the sheet-like bread pieces w1 with ears that have been conveyed to the front ends of the second conveyance lines 5a and 5b and have been waiting are lowered and transferred in an overlapping manner, two sheet-like bread breads with ears are transferred. The confectionery bread intermediate product w2 supplied with the filling F is formed between the pieces w1 and w1.

Specifically, first, as shown in FIG. 7A, in the second transport lines 5 a and 5 b, the bread piece w <b> 1 reaching the tip 61 is stopped by the upper stopper 60. In this case, the bread loaf w1 is pressed by the press rollers 64 and 65, and the space e exists between the tip 61 of the second transport lines 5a and 5b and the upper stopper 60, so the tip of the bread loaf w1 is exposed to the space. To be stopped.
In this state, when the sensor 14 provided in the first transport lines 4a and 4b detects that the bread loaf w1 has reached a predetermined position with respect to the tip positions of the second transport lines 5a and 5b, the lower stopper 62 is predetermined. The bread piece w1 that is projected at the timing of 1 and conveyed on the first conveying lines 4a and 4b is stopped, and as shown in FIG. 7B, the upper stopper 60 is stopped at a predetermined timing and the second conveying is performed. The bread pieces w1 reaching the tips of the lines 5a and 5b are overlapped with the tips of the bread pieces w1 conveyed on the first transport lines 4a and 4b. Thereafter, the lower stopper 62 is moved backward as shown in FIG.

In this case, the bread loaf w1 from the second transport lines 5a and 5b is lowered, but the upper bread loaf w1 is lowered after being stopped by the upper stopper 60, so the timing with the lower bread loaf w1 is adjusted. Therefore, the tips of the upper and lower bread pieces w1 can be reliably aligned with each other.
Furthermore, since the tip of the upper bread piece w1 descends from the state where it is exposed and stopped in the space e between the tips of the second transport lines 5a and 5b and the upper stopper 60, the upper bread piece w1 The tip position can be located at a position very close to the lower bread piece w1, so that the lowering distance can be shortened, so that the tips of the upper and lower bread pieces w1 can be aligned more accurately. .
Furthermore, since the lower bread piece w1 is stopped by the lower stopper 62 and waits for the bread piece w1 from the upper side, the tips of the upper and lower bread pieces w1 can be aligned more accurately in this respect as well. Will be able to.
In the stacking device 13, as described above, it is desirable to provide two press rollers, an upstream press roller 64 and a downstream press roller 65, as the press rollers provided behind the upper stopper 60. First, the upstream side press roller 64 moves the rear part of the bread piece w1 when the bread piece w1 of the second conveyance lines 5a and 5b passes through the downstream side press roller 65 and falls onto the first conveyance lines 4a and 4b. When the bread piece w1 is lowered and overlapped with the bread pieces on the first transport lines 4a and 4b by bending the tip of the bread piece w1 forwardly tilted by pressing, the upper and lower bread pieces It is possible to prevent as much as possible the occurrence of misalignment in the superposition of the tips.
In addition, the downstream presser roller 65 has the bread stoppers w1 and w1 on which the upper stopper 60 provided in the second transport line reaches the respective leading end portions of the second transport lines 5a and 5b and is prevented from advancing. When the lift is released by stopping the release, by pressing the vicinity of the tip of the bread piece, the tip of the bread piece that has been in contact with the stopper is lifted by a mask or adhesive, and the bread piece is bent. When the timing of the descent is wrong and the bread pieces w1 and w1 are overlapped with the bread pieces on the first transport lines 4a and 4b, it is possible to prevent the top and bottom bread pieces from being misaligned. Will be able to.
The rotation shaft 64a of the upstream side presser roller 64 is pivotally supported in a long hole 67 provided in the bracket 66 so that the upstream side presser roller 64 can swing up and down. By doing so, when the bread piece w1 is pressed or even when the bread piece is thick, stress is not excessively applied to the bread piece.
The presser roller may have a configuration (columnar or cylindrical) in which the outer peripheral surface of the rotating shaft is pressed in direct contact with the bread piece, but the width provided on the rotating shaft is narrow as in this embodiment. It is desirable to have a disc-shaped configuration. By using a narrow presser roller in this way, the area in contact with the bread piece is reduced, and stress is not applied to the bread piece.

  The above is performed successively in succession, and the overlapped sweet bakery intermediate product w2 is further conveyed forward.

Next, the confectionery bread intermediate product w2 reaches the overlapping position adjustment mechanism 70, and the overlapping position of the two overlapping bread pieces is adjusted again. Here, as shown in FIGS. 8 (a) and 8 (b), first, the finger advance / retreat section 72 advances the finger 71 to the moving path of the sweet bun intermediate product w2. In this state, as shown in FIG. 8 (c), the finger gripping drive unit 73 moves the pair of left and right upstream of the finger 71 that has advanced into the moving path forward, and in synchronism with this, the follow drive unit 76. However, the finger advance / retreat part 72 is moved to the downstream side at the same speed as the movement of the bread by the conveyor to hold the sweet bread intermediate product w2.
For this reason, even if there is some deviation between the upper and lower bread pieces w1 in the above-described superposition, this is corrected and the upper and lower bread pieces w1 are surely matched. In this case, as shown in FIG. 1, since the finger 71 presses the four corners of the bread piece w1, the left and right front and rear pressing is ensured, and the upper and lower bread pieces w1 are more reliably matched. .
When the gripping of the fingers 71 is finished, the finger gripping drive unit 73 retracts the pair of left and right upstream of the fingers 71 backward, and the finger advance / retreat unit 72 causes the fingers 71 to retract from the moving path of the bread. Then, the follow driving unit 76 returns the finger advance / retreat unit 72 to the upstream side.

  The above is performed sequentially in succession, and the overlapped pastry bread intermediate product w2 is further conveyed to the front food punching die device 16.

  As shown in FIGS. 1, 2, 9 and 10, the food punching die device 16 is provided with a delivery transport unit 17 on the upstream side thereof, and reaches the tip of the first transport lines 4 a and 4 b. The confectionery bread intermediate product w <b> 2 is sequentially received and transferred to the upper surface of the lower die 19 on the upstream side p <b> 1 of the transport chains 18, 18 rotated in synchronization with the delivery transport unit 17. In the delivery conveyance unit 17, the stopper 79 advances on the upstream side of the lower die 19 and temporarily stops the pastry bread intermediate product w <b> 2 before being transferred to the lower die 19. Therefore, the delivery timing of the sweet bun intermediate product w2 onto the lower punching die 19 is adjusted, and the central portion of the confectionery bread intermediate product w2 is reliably positioned on the center of the lower punching die 19.

  In this case, each lower die 19 is guided by a guide rail 82 whose protrusion 81 defines differently from the track of the transport chain 18. In particular, the guide rail 82 has a portion corresponding to the upstream sprocket 18 at the stage where the upper surface of the lower punching die 19 is as early as possible when the lower punching die 19 receives the confectionery bread intermediate product w2 from the delivery conveyance unit 17. Since it is formed in another track that is not a circular track along the sprocket 18 so as to be horizontal, the lower punching die 19 should be in a posture that makes it easy to receive the confectionery bread intermediate product w2 from the delivery transport unit 17. It is possible to receive it reliably.

Thus, when the lower punching die 19 moves from the p1 to the downstream side by the distance L1 (see FIG. 9) and reaches the first specific position p3, the power drive cylinder device 33 of the guide support 20 is immediately extended to the upper side. As shown in FIG. 18, the punch 21 is lowered, and the lower punch 19 and the upper punch 21 are opposed to each other, and the pastry bread intermediate product w <b> 2 on the lower punch 19 is firmly sandwiched. The pressure when sandwiching bread is 3 to 10 kg / cm ^2, preferably 4 to 6 kg / cm ² . This clamping state is continued during the movement of the transport chains 18 and 18 by the distance L2 (see FIG. 9) again due to the synchronized downstream movement of the transport chains 18 and 18 and the guide support body 20 (specifically). In this embodiment, it is 0.5 to 1.0 second, preferably 0.7 to 1.0 second), and the movement of this distance L2 is completed, and the lower die 19 is the second specified When the position p4 is reached, the power drive cylinder device 33 is shortened and the upper die 21 is raised.

  At this time, the entire lower surface of the upper punching die 21 and the entire upper surface of the lower punching die 19 face each other, and the confectionery bread intermediate product w2 is continuously applied over an arbitrary fixed time on the entire pressing surfaces of the upper and lower punching dies. As shown in FIG. 17, the upper and lower sheet-like bread pieces w1, w1 and w1 of the pastry bread pieces w1 and w1 are securely crimped as shown in FIG. 17, and the cutting target position s1 is reliable. Can be cut. At this time, since the lower die-cutting die 19 is placed on the lower die-cutting die rail 91 at the outer surface protruding end portion 25c of the die main body 25, the lower die-cutting die 19 is stronger when pressed against the confectionery bread intermediate product w2. A force can be applied (see FIGS. 10 and 14). At this time, almost no pressing force is applied to the inner portion of the press-bonding target position s2 of the confectionery bread intermediate product w2 in the recessed portions 26d and 36c, and as a result, a square shape having a plump feeling on the lower die 19 is obtained. The pastry bread w3 is formed, and the bread lobe portion w4 as shown in FIGS. 9, 15 and 18 is left around the side surface of the lower die 19.

  As the upper punching die 21 is raised, the guide support 20 is returned to the upstream original position, and the following operations are repeated. Although only the operation of the power drive cylinder device 33 has been described above, the power drive cylinder device 34 is also extended as necessary to give the marking 22 in the second and subsequent iterations.

  At this time, if the burning mark 22 is kept in a descending state for an excessively long time, the mark display of the sweet bun w3 is darkened so that it is raised at a point earlier than the upper punch 21 as necessary. Thereafter, the above processing by the upper and lower punching dies 19 and 21 and the brand mark 22 is repeated for each pastry bread intermediate product w2 placed on the lower punching die 19.

  In this case, since the reciprocating drive mechanism of the guide support body is constituted by the crank mechanism 101, the reciprocating motion is reliably performed without stagnation. In particular, as shown in FIGS. 9 and 12, the crank mechanism 101 operates the link 105 by means of a disk 104 rotated by a drive motor 103. There is no stagnation in the turn-back, so that the reciprocating motion is performed smoothly. As a result, the upper punching die 21 and the lower punching die 19 are continuously pressed against the pastry bread intermediate product w2 in combination with the descending / raising operation to strongly press the peripheral press-bonding planned portion (crimping target position s2). be able to.

  When one lower die 19 is moved forward from the second specific position p4 and reaches the vicinity of the front end position p2 shown in FIG. 9, the roller 30 of the lower die 19 is moved sideways. When viewed from above, the cam plate 38 is pushed and displaced to the outer periphery of the head of the substantially tear-shaped cam plate 38, and the extruded body 27 protrudes slightly from the upper surface of the lower die 19 through the recess 26d. The lower part of the confectionery bread w3 fitted in the part 26d is pushed out of the recessed part 26d. The extruded body 27 is maintained until it reaches the front end of the lower portion 18b and moves toward the rear side of the lower portion 18b. The extruded body 27 is immersed in the lower portion 26d, and the bottom of the lower portion 26d is reached until the intermediate position of the lower portion 18b is reached. It becomes to be displaced to the deeper position.

In this case, since the extruded body 27 pushes the lower part of the confectionery bread w3 fitted in the recessed portion 26d to the outside of the recessed portion 26d, it can be reliably removed from the lower punching die 19. Further, since the extruded body 27 protrudes when the roller 30 of the lower die 19 is pushed by the cam plate 38, the operation is smoothly and reliably performed by the cam.
In addition, the guide rail 82 is inclined at the portion corresponding to the sprocket 80 on the downstream side thereof so that the upper surface of the lower die 19 is inverted to the lowest possible stage when the lower die 19 is handed over the pastry bread. In order to avoid this, it is formed with another track that is not a circular track along the sprocket 80. As a result, it is possible to avoid that the upper surface of the lower die 19 is horizontal or steeply inclined as late as possible, so that the lower die 19 can be taken out of the confectionery bread to the downstream conveyor conveyor 43. The posture can be easily delivered, and this delivery is facilitated.

  By the way, when the lower punching die 19 reaches the forward downward inclined position in the upper half range of the arc-shaped portion 18c of the transport chain 18, the confectionery bread w3 placed on the upper surface of the lower punching die 19 is taken out by gravity. The bread lobe portion that is dropped or transferred onto the conveyor 43 and the pair of downward projecting members 41a and 41b of the first interference means 39 are externally fitted to the side surface of the lower die 19 W4 is pressed downward so as not to come out of the lower die 19 (see FIGS. 9 and 15).

Then, when the lower punching die 19 reaches the front rising inclination position of the lower half range of the arc-shaped portion 18c of the transport chain 18, the pair of upward projecting members 42b of the second interference means 42 The bread lobe portion w4 externally fitted to the side surface is displaced so as to be extracted from the lower punching die 19, and dropped onto the take-out conveyor 44 (see FIG. 9).
As a result, the confectionery bread w3 is carried out to a specific place by the take-out conveyer 43, and the bread lobe w4 is carried out laterally by the take-out conveyer 44.

In the above-described embodiment, the product forming is described under the configuration in which the product is continuously conveyed. However, the product that is intermittently conveyed can be similarly implemented and is within the scope of the present invention.
Furthermore, in the above-described embodiment, the aspect in which two filling supply devices are provided in each first transfer line has been described. However, in the above-described embodiment, one filling supply device is added for each first transfer line. Then, by providing three filling supply devices (not shown), it is possible to supply three types of fillings to the upper surface of the sheet-like bread loaf w1 with ears on the first conveyance line. In this case, in particular, the tip discharge port of the conduit means of each filling supply device is formed into a flat plate shape, and the filling is pushed out into a wide plate shape. And can be placed in a three-layered state, or a pastry bread intermediate product w2 in which another ear-like sheet-like bread piece w1 is placed on the ear-like sheet-like bread piece w1 is used for the above food. By pressing / separating with a punching die device, a sandwich sandwiched with three different fillings in a laminated state can be easily manufactured.
In addition, if an individual modification is demonstrated with reference to FIG. 19, FIG. 19 is a perspective view which shows the modified lower side cutting die 19. FIG.
In this example, the mold main part 26 is removed, and instead, a separately prepared mold main part 26A is fixed. This die main portion 26A is formed with a bridging portion 26e at the center of the upper surface of the previous die main portion 26, and a cut surface portion 26b 'continuous at the same height as the cut surface portion 26b is formed at the center of the width of the bridging portion 26e. In addition, a pressing surface portion 26c ′ continuous to the pressing surface portion 26c is formed on both sides in the width direction of the cut surface portion 26b ′. Others have the same structure.

In this case, it is assumed that the mold main part 36 of the upper die is also removed and replaced with a mold main part corresponding to the mold main part 26A. The corresponding main part of the mold has a lower surface symmetrical to the upper surface of the main part 26A of the mold, and corresponds to the previous cut surface parts 26b and 26b ′, the pressing surface parts 26c and 26c ′, and the recessed part 26d. Shall be.
Further, the mark 22 is removed, and instead, two relatively small diameter marks are fixed at specific positions on the output portion of each power telescopic cylinder device 34.

In the use of this modification, the filling F is supplied to two specific places on the upper surface of each sheet-like bread piece w1 by the filling supply devices 8a, 8b, 9a, 9b. It operates according to the case of the embodiment. In this operation, when the lower die 19 reaches the second specific position p4, two independent confectionery breads of half size of the confectionery bread w3 manufactured in the previous embodiment are formed on the main part 26A of the mold, Moreover, the mark display by the contact of each baking mark is baked on the upper surface of each of the two confectionery breads. These two confectionery breads are pushed up onto the upper surface of the main part 26 </ b> A by the pressing body 27, and are simultaneously dropped or transferred onto the take-out conveyer 43. At this time, the bridging portion 26e enters the deep groove 27a in the diameter direction of the pressing body 27, and the collision between the pressing body 27 and the bridging portion 26e is avoided. The other points are not substantially different from those of the previous embodiment.
As another modified example, in the modified example, the cut surface portion 26b ′ of the main portion 26A of the lower die 19 and the corresponding cut surface portion of the main portion of the upper die are not provided. Alternatively, these cut surface portions are lower (shorter) than the height of the cut surface portion of the outer peripheral edge, or are not continuously formed at the same height as the cut surface portion of the outer peripheral edge, and are partially formed in a sawtooth shape or an intermittent shape. You may make it do. Thus, the two independent confectionery breads of the half size can be molded so that they can be easily separated in a state where they are combined on one side.

  This modification is merely an example, and various modifications can be made by modifying the main portions 26 and 36 of the upper punching die 21 and the lower punching die 19 of the previous embodiment, as well as the deep groove 27a of the pressing body 27 and the like. It becomes possible to produce a confectionery bread of the form.
