The above-mentioned extrusion device is a device that divides viscous materials such as rice cakes and creams, and is suitable for extruding food materials containing fibrous substances cooked from meat or vegetables as an inner packaging material such as Chinese buns. Absent. That is, when the food material is divided by the wire-shaped cutter disclosed in Patent Document 1, meat streaks or the like contained in the food material are caught on the wire, and the amount gradually increases to make the cutter look thicker. Therefore, there is a problem that the extrusion port becomes narrow and the extrusion of the food material is hindered and the divided weight is disturbed.

Further, when the food material is divided by the valve member disclosed in Patent Document 2, the food material is sandwiched between the valve member and the extrusion port, and the divided weight is disturbed, or the food material is crushed. There is. Further, there is a problem that the outer shape of the valve member is substantially spherical and the flow path of the food material formed between the inner wall of the nozzle is narrowed and the flow of the food material is hindered.

According to the present invention, the rotary cutter for dividing the food material as in the prior art is not wire-like, and a plate-like rotary member is provided in the nozzle so that the plate surface is substantially parallel to the flow-down direction of the food material. By forming the frontal shape of the member in a triangle or bell shape, it is possible to prevent the food material from being caught by the rotating member, and it is possible to prevent the flow path from being reduced due to this catching.

In addition, a substantially spherical valve member that opens and closes the extrusion port is not provided in the nozzle as in the prior art, and a space surrounded by the rotating member and the inner wall of the nozzle is formed wide by providing the rotating member having the structure described above. Therefore, even a food material containing solids can be stably extruded without stagnation.

In addition, the food material is not cut and separated using a knife or scissors equipped with a sharp blade as a means for dividing the food material, and the rotating member is provided to be rotatable in the circumferential direction of the nozzle in the nozzle, By rotating the food material in the nozzle in accordance with the rotation of the rotating member, a position shift occurs between the food material in the nozzle and the extruded food material to form a shear surface, and this shear surface is bounded. As the food material is divided, it is possible to divide the food material without damaging it.

Moreover, it becomes possible to suppress disturbance of the divided weight of the food material with the above effect.

Hereinafter, an extrusion device 3 according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front explanatory view showing an outline of the packaging device 1 provided with the extrusion device 3. FIG. 2 is an explanatory front view showing an outline of the extrusion device 3. FIGS. 3A to 3D are explanatory views showing an extrusion process of the inner packaging material B by the extrusion device 3.

The wrapping apparatus 1 is an apparatus that wraps an inner wrapping material B of a Chinese bun tool material with a skin material A of a Chinese bun dough, for example, and forms a food product C that is a Chinese bun. The packaging device 1 includes an extrusion device 3, a pallet conveyor 5, a sealing device 7, and a control device 9.

The extrusion device 3 is a device that is disposed above a pallet conveyor 5 to be described later and supplies the inner packaging material B to the skin material A conveyed by the pallet conveyor 5. The extrusion device 3 includes a supply unit 31 that accommodates and transports the inner packaging material B, and a nozzle unit 35 that is movable in the vertical direction and communicates with the supply unit. The supply unit 31 includes a hopper 32 that contains the inner packaging material B and a pair of screws 33 at the bottom of the hopper so as to be rotatable inside each other. Furthermore, a vane pump 34 is provided in communication with the hopper 32 in the distal direction of the screw 33 (left direction in FIG. 2). The screw 33 and the vane pump 34 are interlocked and coupled to a control motor (not shown) and are driven to rotate intermittently. The supply unit 31 is a known feeding mechanism, and detailed description thereof is omitted. In addition, the supply part 31 should just be a mechanism which can supply the inner packaging material B to the nozzle part 35 stably, and may be supply apparatuses other than a present Example.

The nozzle part 35 is for extruding and dividing the inner packaging material B supplied from the supply part 31. The nozzle part 35 includes a cylinder 36 that communicates with the vane pump 34 via a soft communication pipe 31A, and a nozzle 37 is fastened to the lower surface of the cylinder 36 so as to be detachable and replaceable. The nozzle 37 includes an inclined portion 37A whose inner surface shape is inclined so as to reduce its diameter toward the extrusion port 37D on the lower surface, and a vertical portion 37B continuous below the inclined portion 37A.

A rotating member 38 is rotatably disposed inside the nozzle 37. The rotating member 38 includes a rotating shaft 38A disposed coaxially with the central shaft 37E of the nozzle 37, and a rotating plate 38B integrated therewith by welding or the like below. The rotary shaft 38A is rotatably fitted in a through hole 36A provided in the upper part of the cylinder 36, and is connected to a rotation drive unit 4 described later. A known sealing member such as an O-ring (not shown) is attached to the through hole 36A to prevent the inner packaging material B from flowing out.

The rotating plate 38B is a plate-like member (see FIG. 3C), and the plate surface shown in FIG. 1 is provided vertically so as to follow the direction in which the inner packaging material B flows down. Further, the front view shape is an isosceles triangle as an example, and the side surface 38C is formed in a divergent shape inclined from the top of the head toward the end of the bottom surface 38D. Further, the rotating plate 38B is spaced from the inner wall of the nozzle 37 to provide a gap. By providing the rotating plate 38B in such a shape, even if the inner packaging material B includes a fiber material (for example, meat streaks), the fiber material extends along the inclined side surface 38C of the rotating member 38. It can flow down and pass through the gap. Therefore, it is possible to prevent the fiber from being caught on the rotating plate 38B, and it is possible to prevent the flow path from being reduced due to the catch. Further, the horizontal cross section of the rotating plate 38B is gradually widened as it approaches the extrusion port 37D by providing the side surface 38C so as to be inclined toward the end. Accordingly, the flow path through which the inner packaging material B flows is gradually narrowed as it approaches the extrusion port 37D, and the density of the inner packaging material B flowing through the nozzle 37 can be gradually increased by the change, so that the inner packaging material B falls. There is an effect to suppress. The bottom surface 38D is formed on a substantially horizontal plane.

On the other hand, by making the rotary plate 38B into a plate shape, the flow path of the inner packaging material B in the nozzle 37 can be widely formed, and even the inner packaging material B containing solid matter can be stably extruded without stagnation. It becomes possible.

The rotational drive unit 4 for rotationally driving the rotational member 38 is erected on the upper surface of a support plate 39 that supports the cylinder 36 from its upper surface. The drive mechanism will be described. A mounting bracket 41 is erected on the upper surface of the support plate 39, and a control motor 42 is fixed on the upper surface of the mounting bracket 41 so that the rotation output shaft 42A is directed downward. The rotation output shaft 42A and the rotation shaft 38A of the rotation member 38 that passes through the cylinder 36 and protrudes from above the support plate 39 are connected via a connection member 43 such as a coupling. And the control motor 42 rotates based on the command from the control apparatus 9 mentioned later. The driving source for rotating the rotating member 38 is not limited to the control motor 42, and may be a known rotating device, for example, a rotary actuator that is rotated by a fluid pressure such as air pressure. Further, the rotation member 38 and the drive source may be provided in an interlocking manner through a power transmission mechanism such as a gear.

The support plate 39 is provided with a fabric presser 45 that clamps the peripheral portion of the outer covering material A together with the pallets 55A and 55B when the inner packaging material B is pushed out from the nozzle portion 35 onto the outer covering material A. The fabric presser 45 includes an annular presser member 46 that presses the outer skin material A directly from above, and a round bar-like slide shaft 47 that supports the presser member 46, and a bearing that is erected on the upper surface of the support plate 39. The sliding shaft 47 is fitted into the member 48 so as to be movable up and down, and a coil spring 49 is mounted on the sliding shaft 47 between the support plate 39 and the pressing member 46. Therefore, the pressing member 46 is always biased downward by the restoring force of the coil spring 49.

The support plate 39 is provided so as to be movable up and down intermittently by a vertical mechanism (not shown). The vertical movement mechanism may be, for example, a direct-acting pneumatic cylinder provided on a base (not shown), or a cam mechanism or ball screw mechanism linked to a control motor. Then, as the support plate 36 moves up and down, the nozzle portion 35 and the fabric presser portion 45 move up and down so as to approach and separate from the outer skin material A conveyed below.

The pallet conveyor 5 is a conveying device that intermittently conveys the substantially circular outer shell material A in the horizontal direction (left-right direction shown in FIG. 1). The pallet conveyor 5 is provided with a pair of endless chains 51 wound around a plurality of sprockets (not shown). A plurality of pairs of left and right pallets 55 </ b> A and 55 </ b> B that are held openably and closably by the frame body 54 are provided inside the pair of chains 51. The pair of left and right pallets 55 </ b> A and 55 </ b> B has a semicircular recess formed at a position facing each other so as to have a circular hole 53 at the joint. Further, the hole 53 provided at the joint of the pallets 55A and 55B is formed so as to be inclined so that the lower diameter is larger than the upper diameter.

Inside the pallets 55A and 55B (lower side in FIG. 1), an endless support belt 57 is provided around a plurality of pulleys (not shown). The support belt 57 is for supporting the skin material A supplied to the hole 53 formed by the pair of pallets 55A and 55B from the lower side. The support belt 57 is provided to run intermittently in synchronization with the running of the chain 51.

The outer skin material A is shaped so that the outer shape of the outer skin material A is substantially circular, and is aligned and conveyed so that the center thereof coincides with the center of the hole 53 of the pallets 55A and 55B. The pallet conveyor 5 is driven and controlled by the control device 9 so as to temporarily stop at a position where the center of the hole 53 (here, synonymous with the center of the skin material A) substantially coincides with the center axis 37E of the nozzle 37. ing.

The sealing device 7 is disposed on the downstream side of the extrusion device 3 above the pallet conveyor 5. The sealing device 7 is provided with a sealing piece 73 supported by a plurality of rotating shafts arranged at equal intervals, for example, so as to be swingable, and by opening and closing an opening 71 formed by the sealing piece 73, an outer covering material. It is a covering device that collects the outer peripheral material A around the periphery so as to wrap the inner packaging material B supplied to A and binds the outer skin materials A together. The sealing device 7 includes a vertical mechanism (not shown) and operates based on a command from the control device 9.

The control device 9 is a device that controls the driving of each part, and includes a start switch that inputs start / stop of each part, an operation display part 91 that inputs operation timing, operation time, or operation speed of each part, A control unit 93 is provided that includes an arithmetic processing unit that inputs and sets a pattern and performs arithmetic processing based on numerical values and the like input to the operation panel, and outputs an operation command to each unit.

Next, the extrusion process of the inner packaging material B by the extrusion apparatus 3 shown in FIG. 3 will be described. FIG. 3A shows a process in which the nozzle portion 35 stands by at the raised position, and the outer skin material A is conveyed by the pallet conveyor 5 and temporarily stopped at a position below the nozzle 37. At this time, the fabric pressing member 46 of the fabric pressing portion 45 is positioned farthest downward relative to the support plate 39.

FIG. 3B shows a process in which the nozzle portion 35 descends and the inner packaging material B is pushed out. As the support plate 39 is lowered, the nozzle portion 35 and the fabric presser portion 45 are lowered so as to approach the outer skin material A. First, the presser member 46 provided in the cloth presser portion 45 comes into contact with the peripheral edge portion of the outer skin material A, and the support plate 39 descends to strongly hold the peripheral edge portion between the pallets 55A and 55B. Further, the extrusion port 37D of the nozzle 37 provided in the nozzle part 35 descends to the inside of the hole 53 formed by the pallets 55A and 55B. Then, the screw 33 and the vane pump 34 of the supply unit 11 are rotationally driven for the set rotational speed and operating time to transport the inner packaging material B, and flow down through the communication pipe 31A, the cylinder 36 and the nozzle 37 and from the extrusion port 37D. Extrude the required amount of the inner packaging material B. Further, the nozzle 37 is raised from the middle of the extrusion process, and the elevation is stopped at a position where the extrusion port 37D coincides with the upper surface height of the pallets 55A and 55B (see FIG. 3C). In this step, the skin material A is pressed by the extruded inner packaging material B and deformed into a bag shape, and the central portion of the skin material A hangs down and is placed on the support belt 57.

FIG. 3C shows a process in which the rotating member 38 rotates in the circumferential direction of the nozzle 37. The rotating member 38 rotates about 180 degrees in the circumferential direction of the nozzle 37 in conjunction with the rotation of the control motor 42. At this time, the inner packaging material B surrounded by the rotating plate 38B and the inner wall of the nozzle 37 rotates in the nozzle 37 as the rotating plate 38B rotates. Further, the inner packaging material B extruded into the bag-shaped outer skin material A is held by the outer skin material A. Therefore, a positional shift occurs between the rotating inner packaging material B in the nozzle 37 and the inner packaging material B in the outer skin material A, and the shear surface S is formed, and the inner packaging material B is divided into a fixed amount. Further, the bottom surface 38D of the rotating plate 38B flattens the upper surface of the inner packaging material B pushed out toward the outer skin material A by the rotation of the rotating plate 38B. The rotation angle of the rotating member 38 may be set as appropriate depending on the physical properties of the inner packaging material B as a food material, and it is sufficient that a positional deviation occurs between the inner packaging material B in the nozzle 37 and the extruded inner packaging material B. Since there are, it does not specifically limit.

FIG. 3D shows a process in which the nozzle portion 35 rises to the standby position after the rotation of the rotating member 38 is completed. As the nozzle 37 rises, the inner packaging material B in the nozzle 37 and the inner packaging material B in the outer skin material A are separated from each other with the shear surface S as a boundary. The division of the inner packaging material B by the rotating member 38 does not use a cutting means such as a knife or scissors with a sharp blade, and causes a positional shift between the food material in the nozzle and the extruded food material. Since the food material is divided, the food material can be divided without being damaged. Further, as described above, it is possible to suppress disturbance of the divided weight of the inner packaging material by stable and constant extrusion and reliable division.

Then, the outer skin material A containing the inner packaging material B is transported to a position below the sealing device 7 by the travel of the pallet conveyor 5 and temporarily stops. The sealing device 7 descends with the opening 71 opened, and stops at a position where the lower surface of the sealing piece 73 forms a slight gap with the upper surfaces of the pallets 55A and 55B. Thereafter, the sealing piece 73 moves in the direction of closing the opening 71, so that the peripheral edge portion of the outer skin material A gathers at the center so as to wrap the inner packaging material B and binds to each other (see FIG. 1). And the foodstuff C which covered the inner packaging material B with the outer skin material A is shape | molded (refer FIG. 1). Thereafter, the encapsulated food C is discharged from the pallet conveyor 5 and subjected to post-processing such as final fermentation and steaming.

Next, an extrusion device 3 according to a second embodiment of the present invention will be described with reference to the drawings. 4A and 4B are explanatory views showing an outline of the rotating member 38 provided in the nozzle portion 35 of the extrusion device 3, wherein FIG. 4A is a front view, FIG. 4B is a side view, and FIG. 4C is a bottom view. The same components as those in the first embodiment will be described using the same reference numerals.

The rotating member 38 shown in FIG. 4A is provided with a plate-like rotating plate 38B whose front view shape is a bell shape. The bell shape means that the shape of the left and right side surfaces 38C connecting the top of the head 38A and the bottom surface 38D is formed by a convex curved surface and a vertical plane. Further, the side surface 38C of the rotating plate 38B is spaced apart from the inner wall of the nozzle 37 over its entire length. Even in such a shape, it is possible to prevent the inner packaging material B from being caught on the rotating plate 38B as in the first embodiment, and it is possible to prevent the flow path from being reduced due to this catching.

The side view shape of the rotating plate 38B shown in FIG. 4B is provided with a slight inclination so that the thickness of the rotating plate 38B extends from the top to the bottom 38D. By providing this inclination, as in the first embodiment (see paragraph 19), the flow path of the inner packaging material B gradually decreases as it approaches the extrusion port 37D, and the density of the inner packaging material B flowing down the nozzle 37 is reduced. Since the height can be gradually increased, there is an effect of suppressing the fall of the inner packaging material B.

Further, referring to FIG. 4C, the plate surface is provided with an uneven surface along the vertical direction. The uneven surface has an effect of directing the flow of the inner packaging material B, and has an action of holding the inner packaging material B when the rotating plate 38B rotates, and the inner surface of the inner packaging material B on the front surface of the rotating plate 38B. It has the effect of reliably rotating while suppressing sliding. The bottom surface 38D is formed in a substantially horizontal plane. Note that the shape of the bottom surface 38D is not limited to a flat surface, and may be a curved surface such as a concave arc surface when viewed from the front. When the rotating plate 38B formed as described above is rotated, a substantially spherical shear surface S is formed between the inner packaging material B in the nozzle 37 and the inner packaging material B pushed out to the outer skin material A, and the divided inner packaging material B is divided. Since the head of the head is leveled into a substantially spherical shape, it is possible to suppress inclusion of air when covered with the skin material A.

Since the rotating plate 38B is plate-like as in the first embodiment, it can be stably extruded without hindering the flow of the inner packaging material B. Moreover, it is possible to divide the inner packaging material B as a food material without damaging it. Further, as described above, it is possible to suppress disturbance of the divided weight of the inner packaging material by stable and constant extrusion and reliable division.

Next, an extrusion device 3 according to a third embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a front explanatory view showing an outline of the extrusion device 3. In addition, the same code | symbol is demonstrated about the structure similar to the said Example.

The extruding device 3 in the third embodiment extrudes three layers of food materials in which three types of food materials B are concentrically stacked. The nozzle portion 35 of the extrusion device 3 is fixed to the lower surface of the support plate 39, and the cylinder 36 and the nozzle 37 that form the flow path of the first food material B1 and the flow of the second food material B2 inside thereof. An intermediate cylinder 63 that forms a path, and a rotating member 38 are rotatably provided inside the intermediate cylinder 63. The cylinder 36 is connected to communication pipes 31 </ b> A and 31 </ b> B communicating with first and second food material supply units (not shown) at left and right communication ports, respectively. The intermediate cylinder 63 includes a through hole 63A communicating with the left communication port and a through hole 63B into which the rotary member 38 is rotatably inserted.

The rotary member 38 includes two tubular rotary shafts 38A and two plate-like rotary plates 38B at the lower end thereof, symmetrically with respect to the rotary shaft 38A. The side surface 38C of the rotary plate 38B is formed by the same inclined surface and vertical plane as in the first embodiment. Further, a gap is provided between the rotating plate 38 </ b> B and the inner wall of the nozzle 37. The bottom surface 38D of the rotating plate 38B is formed on a horizontal plane.

The upper portion of the rotation shaft 38A is provided so as to protrude through the through hole 63B of the intermediate cylinder 63 and above the support plate 39. At the upper end of the rotation shaft 38A, there is provided a communication pipe 31C into which the rotation shaft 38A is rotatably fitted. The communication pipe 31C is connected to a third food material supply unit (not shown).

The rotational drive unit 4 for rotationally driving the rotational member 38 has a mounting bracket 41 erected on the upper surface of the support plate 39, and the control motor 42 on the upper surface of the mounting bracket 41 so that the rotation output shaft 42 </ b> A is directed downward. Is fixed. The drive gear 61A is fixed to the rotation output shaft 42A, and the driven gear 61B is fixed to the rotation shaft 38A to connect the gears 61A and 61B. Then, the rotation member 38 is rotatably provided by the control motor 42 rotating based on a command from the control device 9.

A belt conveyor 8 is provided below the extrusion device 3. The belt conveyor 8 is a device that circulates an endless belt 81 around a plurality of rollers (not shown) and rotates intermittently, and conveys a cup 85. The belt conveyor 8 includes a cradle 83 that can move up and down on the lower surface of the belt 81 at a position below the nozzle 37, and moves up and down so that the belt 81 approaches and separates from the nozzle 37 as the cradle 83 moves up and down. To do.

The cup 85 is conveyed to a position below the nozzle 37 by the rotation of the belt 81, approaches the nozzle 37 as the cradle 83 rises, and temporarily stops. The extruding device 3 extrudes each food material B1, B2, B3 by a predetermined amount all at once and stops. At this time, the food material is filled into the cup 85. Thereafter, the rotating member 38 rotates, and a shear surface S is formed between the food material in the nozzle and the food material on the cup 85 side. Then, when the cup 85 is separated from the nozzle 37 as the cradle 83 is lowered, the extruded food material is separated. The lowered cup 85 is conveyed downstream by the belt conveyor 8.

Thus, even food materials that are extruded in a layered manner are effective as in the first embodiment, and stable extrusion and reliable division are possible.

The description of the extrusion device 3 according to the embodiment of the present invention is generally as described above. However, the present invention is not limited to this and can be modified within the scope of the claims. In the above embodiment, the explanation has been made so that the inner packaging material B as a food material is extruded into the bag-shaped outer shell material A, or the food material B is extruded into a cup-shaped container to be divided. It is also possible to divide by extruding on the upper surface of the substrate.

Further, the shape of the rotating plate 38B provided in the rotating member 38 is not limited to a triangle or a bell shape. The shape of the side surface 38C of the rotating plate 38B may be a shape that does not catch the rotating plate 38B when the fiber material contained in the food material B flows down the nozzle 37, and extends from the top to the end of the bottom surface 38D. It may be formed in a flat shape or a convex shape so as to spread.

In the above embodiment, the inner packaging material B in the nozzle 37 is in a state of being divided into two by the rotating plate 38B. However, when the diameter of the extrusion port 37D is increased, the inner packaging material B may fall from the extrusion port 37D in a state of being divided into two. Accordingly, it is possible to prevent the inner packaging material B from falling by forming the rotary plate 38B with three or four plate-like members with respect to the rotation center axis and partitioning the rotary plate 38B into a plurality of three or four.

Further, although the food material has been described as including solid matter such as meat and vegetables, the sheared surface S can be formed and stable extrusion can be performed even with kneaded dough such as fish meat surimi and salmon.
