Japanese Utility Model Registration No. 3080402

In the above-described conventional confectionery bread manufacturing method, the filling is supplied in an inserted state between the upper bread portion and the lower bread portion formed by cutting the thick bread W as described above. Therefore, it is necessary to temporarily lift the upper bread when supplying the filling, and it takes time and effort, and the amount of the filling cannot be increased so much. There are inconveniences, such as mounting in a state and difficulty in supplying a solid filling. Further, the type of bread cannot be different between the upper bread portion and the lower bread portion of the confectionery bread.
The present invention is intended to address these inconveniences, and has as its object the problem that one sheet-like piece to be conveyed is superimposed on another sheet-like piece. It is an object of the present invention to provide an apparatus for stacking sheet-like pieces so that the pieces can be surely fitted together.

In order to achieve the above object, the present invention forms a first transport line and a second transport line, transports one sheet-like piece by each transport line, and is transported by the second transport line. A sheet-like piece stacking device for stacking one sheet-like piece on each sheet-like piece conveyed on the first conveyance line during conveyance on the first conveyance line,
The tip side of the second transport line, the transport direction of the sheet-like pieces of the second transport line is the same as the transport direction of the sheet-like pieces of the first transport line when viewed from above, and when viewed from the side, The first transport line is disposed at a specific height position in the middle of the first transport line so as to be inclined downward with respect to the transport direction of the sheet-like piece of the first transport line, and is provided on the first transport line. A sensor for detecting that the sheet-like piece of the transport line has come to a predetermined position with respect to the leading end position of the second transport line; and a sensor provided on the second transport line to stop the sheet-like piece reaching the leading end. At the same time, the stop is released at a predetermined timing based on the detection of the sensor, and the leading end of the sheet-like piece from the second transport line is aligned with the leading end of the sheet-like piece transported on the first transport line so as to be overlapped. On the 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 transport line and a second transport line are formed, and one sheet-like piece is transported on each transport line. One sheet-like piece transported by the second transport line is superimposed on each sheet-like piece transported by the first transport line during the transport of the first transport line.
Therefore, for example, in a confectionery bread in which a filling is present between two sheet-like bread pieces, the upper side of the sheet-like bread piece with the ear is vertically cut with one end attached, and the upper side of the sheet-like bread piece with the ear is cut. The conventional processing of lifting from the side and opening it for supplying the filling becomes unnecessary, and therefore, the conveying speed of the sheet-like bread with ears to which the filling is supplied is limited to the sheet-like bread with ears arranged vertically. (Sheet bread pieces with ears) will be increased compared to the conventional treatment, and the filling supply space will be wider than before so that the amount of filling to be supplied can be increased, plate-shaped and laminated. And solidification can be achieved. In addition, the type and thickness of the upper and lower eared sheet-shaped bread pieces can be freely selected, which means that the type and the overall thickness can be easily and freely changed between the two layers. None, with the diversification of the above-mentioned fillings, various textures can be provided.
Further, according to the present invention, the upper stopper provided on the second transport line is stopped and released at a predetermined timing based on the detection of the sensor provided on the first transport line, and the upper stopper from the second transport line is released. The lower sheet-shaped piece is lowered so as to overlap the lower sheet-shaped piece conveyed on the first conveyance line, so that when the upper sheet-shaped piece is lowered, the timing with the lower sheet-shaped piece is adjusted. It can be adjusted, so that the top ends of the upper and lower sheet-like pieces can be surely aligned with each other.

  And it is effective to provide the upper stopper ahead of the tip of the second transport line as needed, and to provide a space between the tip and the upper stopper. Since the leading end of the upper sheet-like piece is exposed to the space between the leading end of the second transport line and the upper stopper and descends from the stopped state, the leading end position of the upper sheet-like piece is changed to the lower sheet. Since it can be located at a position very close to the sheet-like piece, and therefore the descending distance can be shortened, the leading ends of the upper and lower sheet-like pieces can be more accurately aligned.

  Further, if necessary, when the sheet-like pieces are superimposed on the first transport line, the sheet-like pieces are engaged with the leading edge of the sheet-like piece of the first transport line ahead of the leading edge of the second transport line. A lower stopper for temporarily stopping is provided. Since the lower sheet-like piece is stopped by the lower stopper and waits for the sheet-like piece from above, the leading ends of the upper and lower sheet-like pieces can be more accurately aligned at this point. Become.

  Further, if necessary, one or more pressing rollers for pressing the sheet-like piece are provided behind the upper stopper. When the sheet-like piece moves down or lifts due to the release of the stop of the upper stopper, or when the sheet-like piece descends, the sheet-like piece is pressed by one or a plurality of pressing rollers. There is no bending, so that the alignment with the tip of the lower sheet-like piece is performed more reliably.

  Furthermore, if necessary, a superposition position adjusting mechanism for adjusting the superposition position of the two superposed sheets is again provided. Any deviation between the upper and lower sheet-like pieces is corrected, and the upper and lower sheet-like pieces are surely matched.

In this case, the stacking position adjusting mechanism includes a plurality of fingers which advance from the lower side of the moving path of the superposed sheet-like pieces of the first transport line and hold the sheet-like pieces from front and rear, and A finger advancing / retracting portion for advancing to the moving path and maintaining the same for a predetermined time and then retreating; and a finger for moving all or a part of the finger advancing to the moving path in the front-rear direction to clamp the sheet-like piece and retract after the clamping. It is effective to provide a holding drive unit. Since the adjustment is performed by holding the finger, the mechanism is simplified.
Further, it is effective that the fingers are formed to have a substantially L-shaped cross section so as to press the four corners of the sheet-like piece, and a pair of the fingers is provided in front and rear. Since the finger presses the four corner portions of the sheet-like piece, the left-right and front-rear pressing is ensured, and the upper and lower sheet-like pieces are more reliably matched.
In this specification, “forward” has the same meaning as “downstream” in the transport direction, and “backward” has the same meaning as “upstream”.

  According to the sheet-like piece stacking device of the present invention, first, a first transport line and a second transport line are formed, and one sheet-like piece is transported on each transport line. Since one sheet-like piece conveyed by the line is superimposed on each sheet-like piece conveyed by the first conveyance line during the 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 assuming a sheet-shaped bread piece, an ear-shaped sheet-shaped bread part having an ear and 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 becomes unnecessary. Therefore, the conveying speed of the sheet-like bread pieces with ears to which the filling is supplied is vertically arranged. To increase the filling compared to the conventional processing of separating the sheet-like bread slices with ears (sheet-like bread slices with ears), to supply the filling in a wide plate shape, and to place the filling in a multi-layered state. In addition, the space for supplying the filling is widely secured as compared with the related art, so that the supply amount of the filling can be increased and the filling can be solidified. In addition, the type and thickness of the upper and lower eared sheet-shaped bread pieces can be freely selected, which means that the type and the overall thickness can be easily and freely changed between the two layers. None, with the diversification of the above-mentioned fillings, various textures can be provided.

  Further, at a predetermined timing based on the detection of the sensor provided on the first transport line, the upper stopper provided on the second transport line is stopped and released to lower the upper sheet-like piece from the second transport line. Since it is made to overlap with the lower sheet-shaped piece conveyed in the first conveyance line, when the upper sheet-shaped piece descends, the timing with the lower sheet-shaped piece can be adjusted. This has the effect that the tips of the pieces can be surely aligned with each other.

  Hereinafter, an apparatus for stacking sheet-like pieces according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Since the apparatus for stacking sheet-like pieces according to the embodiment of the present invention is used, for example, in a confectionery bread manufacturing apparatus, the explanation will be made here on the confectionery bread manufacturing apparatus. The present embodiment shows one of the most suitable embodiments of the present invention, and does not limit the scope of the present invention.

  In the confectionery bread manufacturing apparatus in which the sheet-like piece stacking device according to the embodiment of the present invention is used, as shown in FIG. 1, the first transfer line, the second transfer line, and the bread stacking device are arranged in two rows.

A slicer 2 and a delivery mechanism 3 for continuously delivering the sliced bread slices w1 with ears one by one as described above are provided.

  As shown in FIGS. 1 and 2, the first transport lines 4a and 4b extend linearly and horizontally forward from each of the two bread slice delivery devices 1A and 1A. The second transport lines 5a and 5b extend straight forward and incline from each of the two bread slice delivery devices 1B and 1B, and are guided to a position about several tens cm higher than the first transport lines 4a and 4b. After being extended horizontally, they are bent at right angles toward the first transport lines 4a, 4b, respectively, guided horizontally horizontally, and extended to above the first transport lines 4a, 4b, respectively. Thereafter, one of the second transport lines 5a is bent forward at a right angle above the first transport line 4a, and then extends linearly and downwardly in an inclined manner, and its tip is located above the halfway point of the first transport line 4a. Similarly, the other second transport line 5b is similarly bent forward at a right angle above the first transport line 4b, and then extends linearly and downwardly in an inclined manner. It is arranged at a specific height position above the middle of 4b.

  At this time, the first transport lines 4a, 4b and the second transport lines 5a, 5b are each continuously or intermittently loaded with a single bread sheet w1 having an appropriate thickness and having ears. It is a conveyor that can be transported. The transport conveyor is preferably an endless transport belt conveyor as the first transport line, or a roller conveyor incorporated in a partial section thereof. As the second transport line, a straight line is an endless transport belt conveyor, or a roller conveyor is incorporated in a part thereof, and a roller conveyor is suitable for a line that is bent at a right angle. In the present invention, in the right angle line that is bent at right angles in the first transfer line and the second transfer line to change the transfer direction of the bread to a right angle, at least a roller conveyor is used for a line before the direction change of the right angle line. Although desirable, in the present embodiment, a roller conveyor is used before and after the direction change.

That is, the sheet-like object from the transport unit 17 is stably received or transferred.

More specifically, as shown in FIGS. 9 to 11, a plurality of lower punches 19 are provided at predetermined intervals, and the conveying means of each lower punch 19 is pivotally supported on both left and right sides of each lower punch 19. It comprises a pair of left and right endless transfer chains 18 to be connected, and a pair of sprockets 80 for circulating the transfer chains 18. Protrusions 81 are provided, and guide rails 82 which engage with the projections 81 of each lower punching die 19 and define the trajectory of each lower punching die 19 differently from the trajectory of the transport chain 18 are adjacent to the path of the transport chain 18. Provided. In particular, the guide rail 82 has a portion 82 a corresponding to the sprocket 80 on the upstream side, and 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 from the delivery / transportation unit 17. Is formed on another trajectory other than a circular trajectory along the sprocket 80 so as to be horizontal. Specifically, as shown in FIG. 11 (a), at a portion corresponding to the sprocket 80 on the upstream side, the lower side punching die 19 which has been conveyed with the guide rail 82 turned upside down is transported. Shortly after the center of the sprocket 80 was passed and the reversal was started so that the upper surface was turned upward, the center point (O1) of the circular orbit drawn by the sprocket 80 was eccentrically inclined by 45 degrees 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 located outside the center point of the sprocket 80. The trajectory is formed when a circle is drawn up to an angle of 90 degrees. Thereby, the lower punching die 19 can be set in a posture in which the confectionery bread intermediate product from the delivery / conveyance unit 17 can be easily received, so that the reception can be reliably performed.
Further, the guide rail 82 is inclined at a position corresponding to the sprocket 80 on the downstream side so that the upper surface of the lower die 19 is inverted to a stage as late as possible when the lower die 19 delivers a confectionery bread. In order to avoid this, it is effective to have another trajectory other than the circular trajectory along the sprocket 80. Specifically, as shown in FIG. 11 (b), at a portion corresponding to the sprocket 80 on the downstream side, the lower side punching die 19 which has been conveyed horizontally with the upper surface of the guide rail 82 facing upward. After passing through the center of the sprocket 80, the trajectory is made as linear as possible, and thereafter, it is formed as a circular trajectory along the circular trajectory drawn by the sprocket 80. This makes it possible to prevent the upper surface of the lower punching die 19 from being horizontal or steeply inclined to a stage as late as possible. The posture can be easily delivered, and the delivery becomes easy.
The guide rail 82 includes a portion corresponding to both the upstream and downstream sprockets 80 as well as the endless transport chain 18 from which the lower punch 19 returns from the downstream sprocket 80 to the upstream sprocket 80. Is provided over almost the entire length of the path of the lower lining 18b, and stabilizes the return conveyance of the lower punching die 19. And it is not in the path of the endless transport chain which sandwiches and presses the confectionery bread intermediate product w2 by the pair of upper and lower punching dies 19 and 21.

  The details of each lower punching die 19 are as follows. As shown in FIGS. 14 to 18, the lower punching die includes a mold main body 25, a rectangular frame-shaped main part 26 provided on the mold main body 25 and crimping around the bread, and a mold main body 25. An extruding body 27 that can be moved to two positions: an immersion position that is provided to immerse in the main part 26 of the mold; , And a spring 31 that constantly urges the extruded body 27 to the immersion position.

  That is, as shown in FIG. 14, a mold main body 25 is provided, and a main mold part 26 is fixed on the upper surface of the mold main body 25 so as to be replaceable. A guide recess 25a is formed at the center of the upper part of the mold body 25, and a vertically oriented guide hole 26a is formed at the center of the main part 26 of the mold, and a deep groove in the diameter direction shown in FIG. The extruded body 27 having the formed 27a is loosely fitted, and two vertical holes 25b, 25b are formed in the thick portion at the bottom of the mold body 25, and slide into the vertical holes 25b, 25b, respectively. The upper ends of the sliding bars 28 are screwed to the lower surface of the extruded body 27, and the lower ends of the sliding bars 28, 28 are connected by a connecting member 29. A roller 30 is provided on the lower surface side of each of them, and a compression spring 31 is extrapolated to each sliding rod 28 located between the connecting member 29 and the lower surface of the mold body 25.

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

  Further, as shown in FIGS. 2, 9 and 10, the present apparatus is provided with an extruded body moving mechanism 90 for moving the extruded body after the pressing of the bread is completed. The extruded body moving mechanism 90 engages with the roller 30 as a cam follower provided on each extruded body 27 and the roller 30 of the extruded body 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 extruded position.

  That is, a vertical cam plate 38 is provided between the two sprockets 80 on the downstream side of the transport chains 18, 18, and the cam plate 38 has a substantially tear-like shape (Rakkyo shape) when viewed from the side. The outer periphery of the head is engaged with the roller 30 of the lower punching die 19 to vertically displace the extruded body 27 with respect to the die body 25. The roller is 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 transport chain 18, 18 to the time when it passes the arcuate portion 18 of each transport chain 18, 18. The pusher 30 is engaged with and pressed against the outer peripheral edge of the head of the cam plate 38 to move the extruded body 27 to the pushed-out position, and to maintain the state of being pushed up toward the upper surface side of the main part 26 of the mold.

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 the front-rear guide track 32 fixed to the upper part of the stationary table 23. In addition, power driving cylinder devices 33 and 34 for vertically moving the upper punching die 21 and the branding mark 22 independently are provided at front and rear portions of the guide support 20.
In the present embodiment, two upper punches 21 and two brands 22 are provided on one guide support 20 in parallel in the width direction.

  By the way, the upper punching die 21 is configured as follows, that is, as shown in FIGS. 9, 14 and 18, the die main body 35 fixedly connected to the output portion of the power drive cylinder device 33. And a main part 36 which is fixed to the lower surface of the lower part so as to be exchangeably mountable. The main part 36 is formed in a rectangular shape like the main part 26 of the lower punching die 19 and has a lower surface. Is symmetrical with the shape of the upper surface of the main part 26. Thus, as shown in FIG. 14, the lower surface of the main mold portion 36 has a cut surface portion 36a located on the outer peripheral edge thereof, and a pressing portion forming a relatively shallow concave surface located along the inside of the cut surface portion 36a. A surface portion 36b and a square-shaped concave portion 36c formed relatively deep inside the pressing surface portion 36b are provided.

On the other hand, in the branding 22, the mark main body 37 is fixedly connected to the output portion of the power drive cylinder device 34, and a heater (not shown) is provided inside the mark main body 34, and the lower surface of the mark main body 37 is provided with the heater. A mark portion to be heated by the heater is formed.
Along the trajectory of the upper end portion 18a and the lower end portion 18b of the endless transfer chain 18, the lower punching die 19 connected to the endless transfer chain 18, particularly around the outer surface of the die body 25, is provided. The lower punching rail 91, which slides on the outer surface protruding end 25c formed in a laterally convex shape, is parallel to the upper portion 18a and the lower portion 18b of the endless transport chain 18, respectively. (See FIGS. 10 and 14). Thereby, while the conveyance of the lower punching die 19 is further stabilized, the upper punching die 21 descends on the lower punching die 19 to pinch and press the confectionery bread intermediate w2 in the upper part 18a. Even stronger forces can be applied.

  The reciprocating drive mechanism 100 of the guide support 20 is constituted by a crank mechanism 101 as shown in FIG. The crank mechanism 101 is provided on the main body of the apparatus, 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 provided coaxially with the rotation shaft 102 of the drive motor 103. It is configured to include a disk 104 rotated by a motor 103 and a link 105 whose one end is pivotally supported by the guide support body 20 and whose other end is pivotally supported at a position eccentric to the axis of the disk 104. .

  As shown in FIG. 9, a first interference means 39 is provided near the downstream end of the upper part 18a of each of the transport chains 18, 18, and the interference means 39 is provided as shown in FIG. In addition, a main body member 40 fixed to the stationary table 23 and a pair of left and right downward projecting members 41a and 41b fixed thereto are provided. At this time, the pair of downward projecting members 41a and 41b are extended forward and downward so as to be located near 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 done.

  The second interference means 42 is fixed to the stationary table 23 in the lower half range of the arcuate portion 18c of each of the transport chains 18, 18. Like the first interference unit 39, the second interference unit 42 includes a main body member 42a fixed to a lower portion of the stationary table 23, and a pair of right and left upwardly extending left and right portions of the main body member 42a projecting forward and upward. The pair of left and right upwardly extending members 42b extend forward and upward so as to be located near the left and right outer sides of the track of the lower punching die 19, and have a height position and a right and left position. The direction distance can be changed and adjusted.

  A conveyor 43 for taking out the confectionery bread w3 extends forward from the vicinity of the front ends of the arc-shaped portions 18c, 18c of the transport chains 18, 18, on the front side of the food punching device 16, and the transport chains 18, 18 are provided. The conveyer 44 for taking out the bread ear w4 extends laterally from the lower side of the arc-shaped portions 18c, 18c.

Therefore, when a confectionery bread is manufactured by this confectionery bread manufacturing apparatus, the following operation is performed, for example. This will be described with reference to the flowchart shown in FIG.
The filling F is accommodated in the tank 10 of the filling supply devices 8a, 8b, 9a, and 9b, and three loaves of bread loaf w are supplied to the bread slice delivery devices 1A and 1B. In addition, when the filling F or the bar-shaped bread w is consumed, it is appropriately replenished.
In this state, the respective parts are brought into the operating state, whereby the slicer 2 slices the bar-shaped bread w in the bread slice sending devices 1A and 1B to form a sheet-like bread piece w1 with ears having an appropriate thickness. And the 2nd conveyance line 4a, 4b, 5a, 5b starts a continuous feeding movement. On the first and second transport lines 4a, 4b, 5a and 5b, the delivery mechanism 3 of each of the bread slice delivery devices 1A and 1B is provided with one sheet-shaped bread slice w1 with ears previously formed by a slicer. Are sent out and placed one after another.

  One piece of bread sheet w1 with ears placed on the first transport lines 4a and 4b sequentially reaches the filling supply position, but one piece of bread sheet w1 with ears reaches this filling supply position. Then, the pump 11 of the filling supply device 8a, 8b, 9a, 9b is operated, and the filling F in the tank 10 is placed on the upper surface of one sheet-like bread piece w1 with ears on the first transport line, such as cream or jam. Is supplied by a predetermined amount. This supply is performed for each sheet-like bread slice 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, 9b is operated for each of the first transport lines 4a, 4b, respectively. When two kinds of fillings are to be supplied for each piece of bread sheet 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 slices w1 with the ears supplied with the filling F are sequentially transported to the position of the bread stacking devices 13, 13 by moving the first transport lines 4a, 4b.

  While one of the operations of the first transport lines 4a and 4b, the second transport lines 5a and 5b transport the sheet-like bread slices w1 with ears placed thereon, and thereby each of the sheet-like bread slices with ears. As described above, w1 reaches the tip of each of the second transport lines 5a and 5b arranged at a specific height above each of the first transport lines 4a and 4b.

  In this transport 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 to a right angle, as shown in FIGS. Operates 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 slice w1 in a direction perpendicular to the traveling direction of the roller conveyor 51. As a result, the bread slice w1 is delivered to the downstream conveyor whose traveling directions are different at right angles, and the direction is changed. In this case, the trajectory of the rod 53 is defined by the guide rail 55, and the rod 53 is immersed below the upper end of the roller 51 on the pushing end side by the guide rail 55. Therefore, the bread piece w1 can be sufficiently pushed without interfering with the downstream conveyor, and the direction is changed by reliably transferring the bread piece w1. Further, since the plurality of rods 53 are provided in the holding body 54 in a comb shape, the rods 53 can be pushed over the entire length of the rear end of the bread piece w1, and can be pushed securely without disturbing the posture. Further, since the cylinder 57b of the actuator 57 is rotatable so as to follow the trajectory of the rod 53, the operation is performed smoothly.

  By the way, the sensor 14 is operated in the bread stacking devices 13 and 13 as described above, and based on the detection signal, the sheet-like bread slice w1 with ears is placed and transported on the first transport lines 4a and 4b. The sheet-like bread slice w1 with ears that has been transported to the ends of the second transport lines 5a and 5b and has been waiting is lowered and transferred in an overlaid manner. The confectionery bread intermediate 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 1 reaching the tip 61 is stopped by the upper stopper 60. In this case, the bread piece w1 is pressed by the pressing rollers 64 and 65, and the space e exists between the leading end 61 of the second transport lines 5a and 5b and the upper stopper 60, so that the leading end of the bread piece w1 is exposed to the space. And stopped.
In this state, when the sensor 14 provided on the first transport lines 4a and 4b detects that the bread piece w1 has come to a predetermined position with respect to the tip positions of the second transport lines 5a and 5b, the lower stopper 62 The bread piece w1 that is projected and conveyed on the first conveying lines 4a and 4b is stopped at the timing shown in FIG. 7, and the stop of the upper stopper 60 is released at a predetermined timing as shown in FIG. The bread pieces w1 that have reached the ends of the lines 5a and 5b are overlapped with each other so that the ends match the tips of the bread pieces w1 conveyed on the first transport lines 4a and 4b. Thereafter, the lower stopper 62 is retracted as shown in FIG.

In this case, the loaf of bread w1 from the second transport lines 5a and 5b descends. However, since the loaf of upper bread w1 is stopped after being stopped by the upper stopper 60, the timing with the loaf of lower bread w1 is adjusted. Therefore, it is possible to surely match the tips of the upper and lower bread pieces w1 with each other.
Furthermore, since the tip of the upper bread piece w1 is exposed to the space e between the tips of the second transport lines 5a and 5b and the upper stopper 60 and descends from the stopped state, the tip of the upper bread piece w1 is removed. Since the tip position can be located very close to the lower bread piece w1, the descent distance can be shortened, and accordingly, the tips of the upper and lower bread pieces w1 can be more accurately matched. .
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 more accurately aligned in this point as well. Will be able to
In the stacking device 13, as described above, it is desirable to provide two pressing rollers, an upstream pressing roller 64 and a downstream pressing roller 65, as pressing rollers provided behind the upper stopper 60. First, when the bread piece w1 of the second transport line 5a, 5b passes through the downstream press roller 65 and descends onto the first transport line 4a, 4b, the upstream pressing roller 64 moves the rear portion of the bread piece w1. By pressing down, the tip of the bread piece w1 bends forward and bends, so that the bread piece w1 falls on the bread pieces on the first transport lines 4a and 4b and is overlapped. It is possible to minimize the occurrence of misalignment in the overlapping of the tips.
The downstream pressing roller 65 is arranged such that the upper stopper 60 provided on the second transport line reaches each end of the second transport lines 5a and 5b, and stops the bread pieces w1 and w1 that have been waiting on standby. When the bread piece is lifted by stop 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 up by lashing or sticking, and the bread piece is bent. When the falling of the bread slices w1 and w1 is superimposed on the bread slices on the first transport lines 4a and 4b, the displacement of the top and bottom of the bread slices is prevented from being shifted as much as possible. Will be able to
The rotation shaft 64a of the upstream press roller 64 is vertically supported by a long hole 67 provided in the bracket 66 so that the upstream press roller 64 can swing up and down. In this way, when the bread piece w1 is pressed, and even when the bread piece has a large thickness, the bread piece is not excessively stressed.
The pressing roller may have a configuration (columnar or cylindrical) in which the outer peripheral surface of the rotating shaft comes into direct contact with the bread piece and presses the same. However, as in the present embodiment, the narrow width provided on the rotating shaft is reduced. It is desirable to adopt a disk-like configuration. By using the pressing roller having such a small width, the area in contact with the bread piece is reduced, so that stress is not applied to the bread piece.

  The above operations are sequentially and continuously performed, and the superimposed confectionery bread intermediate product w2 is further transported forward.

Next, the confectionery bread intermediate product w2 reaches the stacking position adjusting mechanism 70, and the stacking position of the two sliced bread pieces is adjusted again. Here, as shown in FIGS. 8A and 8B, first, the finger advance / retreat unit 72 causes the finger 71 to advance into the movement path of the confectionery bread intermediate product w2. In this state, as shown in FIG. 8C, the finger holding drive unit 73 moves the pair of left and right upstream sides of the finger 71 that has advanced to the movement path forward, and synchronizes with the movement of the follower drive unit 76. Moves the finger advancing and retreating part 72 to the downstream side at the same speed as the movement of the bread by the conveyor, and clamps the confectionery bread intermediate product w2.
For this reason, even if there is some deviation between the upper and lower bread pieces w1 in the above-mentioned superposition, this is corrected, and the upper and lower bread pieces w1 are surely matched. In this case, since the finger 71 presses the four corner portions of the bread piece w1 as shown in FIG. 1, the left, right, front and back pressing becomes more reliable, and the upper and lower bread piece w1 more reliably matches. .
When the finger 71 has been clamped, the finger clamping drive unit 73 retracts the pair of left and right upstream sides of the finger 71 backward, and the finger advance / retreat unit 72 retracts the finger 71 from the bread bread moving path. Then, the follower drive unit 76 returns the finger advance / retreat unit 72 to the upstream side.

  The above operations are sequentially and successively performed, and the superimposed confectionery bread intermediate product w2 is further conveyed to the food cutting device 16 located further forward.

  As shown in FIGS. 1, 2, 9, and 10, the food punching device 16 is provided with a delivery / transportation unit 17 on the upstream side, and reaches the leading ends of the first transport lines 4 a and 4 b. The confectionery bread intermediate products w2 are sequentially received, and are transferred onto the upper surface of the lower punching die 19 at the upstream side p1 of the transport chains 18, 18 that are rotated in synchronization with the transfer transport unit 17. In the delivery / transport section 17, the stopper 79 advances upstream of the lower punching die 19, and temporarily stops the confectionery bread intermediate product w2 before being transferred to the lower punching die 19. Therefore, the delivery timing of the confectionery bread intermediate product w2 onto the lower punching die 19 is adjusted, and the center of the confectionery bread intermediate product w2 is reliably positioned on the center of the lower punching die 19.

  In this case, each lower punching die 19 is guided by a guide rail 82 whose projection 81 is defined differently from the trajectory of the transport chain 18. In particular, the guide rail 82 has a portion corresponding to the sprocket 18 on the upstream side, and 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 / transportation unit 17. Is formed not on a circular orbit other than the circular orbit along the sprocket 18 so as to be horizontal, so that the lower punching die 19 can be set in a posture that can easily receive the confectionery bread intermediate product w2 from the delivery / transportation unit 17. Yes, it is possible to receive it.

When the lower punching die 19 moves a distance L1 (see FIG. 9) from p1 to the downstream side 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. When the punching die 21 is lowered, the lower punching die 19 and the upper punching die 21 face each other as shown in FIG. 18 and strongly sandwich the confectionery bread intermediate product w2 on the lower punching die 19. The pressure when sandwiching the bread is 3 to 10 kg / cm ^2, preferably 4 to 6 kg / cm ² . This sandwiching state is continued throughout the movement of the transport chains 18, 18 again by the distance L2 (see FIG. 9) due to the synchronized downstream movement of the transport chains 18, 18 and the guide support 20 (specifically). Is 0.5 to 1.0 second, preferably 0.7 to 1.0 second in the present embodiment), the movement of this distance L2 is completed, and the lower punching die 19 is moved to the second specified position. When reaching the position p4, the power drive cylinder device 33 is shortened and the upper punching die 21 is raised.

  At this time, the entire lower surface of the upper die 21 and the entire upper surface of the lower die 19 face each other, and the confectionery bread intermediate product w2 is continuously drawn over an arbitrary fixed time on the entire pressing surfaces of the upper and lower die. As shown in FIG. 17, the upper and lower ear-shaped sheet-shaped bread pieces w1 and w1 of the confectionery bread intermediate product w2 are securely pressed at the press target position s2 as shown in FIG. Can be cut. At this time, since the lower die releasing die 19 is placed on the lower die releasing die rail 91 at the outer surface protruding end 25c of the die main body 25, the lower pressing die 19 is more strongly 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 inside of the crimping target position s2 of the confectionery bread intermediate product w2 in the recessed portions 26d and 36c, and as a result, a plump rectangular shape on the lower punching die 19 is obtained. Is formed, and a bread ear w4 as shown in FIGS. 9, 15, and 18 is left around the side surface of the lower punching die 19.

  The guide support 20 is returned to the original position on the upstream side in accordance with the raising operation of the upper punching die 21, and the same operation is repeated below. Although only the operation of the power drive cylinder device 33 has been described above, in the second and subsequent repetitions, the power drive cylinder device 34 is also extended as necessary so that the branding 22 is applied.

  At this time, if the lowering state of the branding mark 22 is maintained for an excessively long time, the mark display of the confectionery bread w3 becomes dark, so that the branding mark 22 is raised at a point earlier than the upper punching die 21 as necessary. Thereafter, the above-described processing by the upper and lower punching dies 19, 21 and the branding 22 is repeated for each confectionery bread intermediate product w2 placed on the lower punching die 19.

  In this case, since the reciprocating drive mechanism of the guide support 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 the disk 104 rotated by the drive motor 103. There is no stagnation in the switching, so that the reciprocating motion is performed smoothly. As a result, the upper punching die 21 and the lower punching die 19 continue to press the confectionery bread intermediate product w2 together with the lowering / raising operation, and strongly press the peripheral press-fitting scheduled portion (the press-fitting target position s2). be able to.

  Then, when one lower punching die 19 is further moved forward from the second specific position p4 and reaches near the front end position p2 shown in FIG. 9, the roller 30 of the lower punching die 19 is moved sideways. When viewed from above, the push plate 27 is pushed and displaced by the outer peripheral edge of the head portion of the substantially tear-shaped (raky) shape cam plate 38, and the extruded body 27 slightly protrudes from the upper surface of the lower punching die 19 through the concave portion 26d, and becomes concave The lower part of the extruded body 27 at this time is positioned at the lower punching die 19 by the lower punching die 19 and the lower part of the conveyor chain 18 is pushed out of the lower part of the confectionery bread w3 fitted in the 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 concave portion 26d. 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 recess 26d to the outside of the recess 26d, it can be reliably removed from the lower punching die 19. Since the extruded body 27 is protruded by the roller 30 of the lower punching die 19 being pressed by the cam plate 38, the extruded body 27 is operated by a cam, so that the operation is performed smoothly and reliably.
Further, the guide rail 82 is inclined at a position corresponding to the sprocket 80 on the downstream side so that the upper surface of the lower die 19 is inverted to a stage as late as possible when the lower die 19 delivers a confectionery bread. In order to avoid this, it is formed with another trajectory other than the circular trajectory along the sprocket 80. This makes it possible to prevent the upper surface of the lower punching die 19 from being horizontal or steeply inclined to a stage as late as possible. The posture can be easily delivered, and the delivery becomes easy.

  By the way, when the lower punching die 19 reaches the front lowering inclined position in the upper half range of the arcuate 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. A bread ear portion in a state where the pair of downward projecting members 41a and 41b of the first interference unit 39 is externally fitted to the side surface of the lower punching die 19 while being dropped or transferred onto the transport conveyor 43. Press w4 downward so as not to come out of the lower punching die 19 (see FIGS. 9 and 15).

Then, when the lower punching die 19 reaches the forward rising inclined position in the lower half range of the arcuate portion 18c of the transport chain 18, the pair of upwardly projecting members 42b of the second interference means 42 are connected to the lower punching die 19. The bread ear w4 fitted to the side surface is displaced so as to be pulled out 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 and conveyer 43, and the bread ear w4 is carried out laterally by the take-out and conveyer 44.

In the above-described embodiment, the description has been made on the configuration in which the productization molding is continuously conveyed. However, the present invention can be similarly applied to an intermittently conveyed product, which is within the scope of the present invention.
Furthermore, in the above-described embodiment, two filling supply devices are provided for each first transport line. However, in the above-described embodiment, one filling supply device is added for each first transport line. Then, by providing three filling supply devices (not shown), three types of fillings can be supplied to the upper surface of the sheet-like bread piece w1 with ears on the first transport line. In this case, in particular, by making the distal end outlet of the conduit means of each filling supply device flat and extruding the filling into a wide plate shape, three types of fillings are formed on the upper surface of the sheet-like bread slice w1 with ears. Can be placed in a three-layered state, and a confectionery bread intermediate product w2 in which another sheet-like bread piece w1 with ears is placed on the sheet-like bread piece w1 with ears is used for the above-mentioned food. By pressing and separating with a punching die device, it is possible to easily manufacture a sealed sandwich in which three different fillings are included in a stacked state.
Note that individual modifications will be described with reference to FIG. 19. FIG. 19 is a perspective view showing a modified lower punching die 19.
In this example, the main mold part 26 is removed, and a separately prepared main mold part 26A is fixed instead. In the main part 26A, a bridging part 26e is formed at the center of the upper surface of the former main part 26, and a cutting surface part 26b 'is formed at the center of the width of the bridging part 26e at the same height as the cutting surface part 26b. A pressing surface portion 26c 'is formed on both sides in the width direction of the cutting surface portion 26b' and is continuous with the pressing surface portion 26c. Others have the same structure.

In this case, the main part 36 of the upper blanking die is also removed, and the main part corresponding to the main part 26A is fixed instead. 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 includes a part corresponding to the cutting surface part 26b, 26b ', the pressing surface part 26c, 26c', and the concave part 26d. Shall be done.
Further, the branding 22 is removed, and instead, two relatively small branding brands are fixed to the output portion of each power telescopic cylinder device 34 in a specific position.

In the use of this modified example, the filling F is supplied to two specific locations on the upper surface of each sheet-like bread piece w1 by the filling supply devices 8a, 8b, 9a, and 9b. The operation is performed according to the embodiment of the present invention. In this operation, when the lower punching die 19 reaches the second specific position p4, two independent confectionery breads having a half size of the confectionery bread w3 manufactured in the previous embodiment are formed on the main mold part 26A, In addition, the mark display by the contact of each branding mark is printed on the upper surface of each of the two sweet breads. These two confectionery breads are pushed up to the upper surface of the main part 26A by the pressing body 27, and are simultaneously dropped or transferred onto the take-out conveyor 43. At this time, the bridging portion 26e enters the deep groove 27a in the diameter direction of the pressing body 27, and collision between the pressing body 27 and the bridging portion 26e is avoided. In other respects, there is no substantial difference from the previous embodiment.
Further, as another modified example, in the modified example, the cut surface portion 26b ′ of the main portion 26A of the lower punching die 19 and the corresponding cut surface portion of the main portion of the upper punching die are not provided. Alternatively, these cut surface portions are made lower (short) than the height of the cut surface portion of the outer peripheral edge, or are not continuous at the same height as the cut surface portion of the outer peripheral edge, but are partially formed in a sawtooth shape or intermittent shape. You may make it. Thus, the two independent half-size confectionery breads can be molded in a state of being joined at one side and easily separated.

  This modification is merely an example. In addition to the main parts 26 and 36 of the upper punching die 21 and the lower punching die 19 of the previous embodiment, if the deep groove 27a of the pressing body 27 is deformed, various modifications can be made. Can be manufactured.
