The cylinder 17A and the second cylinder 17B of the skin material supply unit 7 are detachably mounted. That is, by providing the left and right walls 15A and 15B (see FIG. 3) and the center wall 15C on the upper surface of the cylinder support base 15, the first wall is provided between the walls 15A, 15B and 15C. , The second cylinders 17A, 17B are formed as cylinder recesses 16A, 16B. Grooves 15G connected to the bottoms of the cylinder housings 16A and 16B are formed in the left and right walls 15A and 15B, respectively. An appropriate gap 18 (see FIG. 1) is provided between the lowermost portions of the first and second cylinders 17A and 17B stored in the cylinder storage portions 16A and 16B and the bottoms of the cylinder storage portions 16A and 16B. Is formed.

  The polymerization nozzle device 9 is detachably mounted on the front side of the cylinder support base 15. That is, a central rising portion continuous with the central wall portion 15C is provided at the left and right central portion (the vertical center portion in FIG. 3) of the upper surface of the front side (the left side in FIGS. 1 and 3) of the cylinder support base 15. 19 are provided, and left and right rising portions 21L and 21R are provided on both left and right sides of the front upper surface. The central portion and the front surfaces (left end surfaces in FIGS. 1 and 3) of the right and left rising portions 19, 21L, and 21R are formed flush with each other, so that the polymerization nozzle device 9 can be detachably mounted. Make up the surface.

  The polymerization nozzle device 9 includes a flange portion 23 having a joining surface joined to the mounting surface. U-shaped engagement grooves 25A, 25B are provided at the upper center and on both left and right sides of the flange portion 23, respectively. , 25C (see FIG. 2). Tightening handles 27A, 27B, 27C which can be disengaged from the engaging grooves 25A, 25B, 25C and can tighten the flange portion 23 are provided at the center rising portion 19 and the left and right rising portions 21L, 21R.

That is, the central tightening handle 27A is provided so as to be able to swing up and down, and the left and right tightening handles 27B and 27C are provided so as to be able to swing right and left.

  Therefore, the fastening nozzles 27A, 27B, and 27C are engaged with the respective engagement grooves 25A, 25B, and 25C of the flange portion 23 of the overlapping nozzle device 9 to fasten the overlapping nozzle device 9 to the front surface of the cylinder support base 15. On the contrary, by separating the fastening handles 27A, 27B, 27C from the engagement grooves 25A, 25B, 25C, the polymerization nozzle device 9 can be removed from the cylinder support base 15. .

  On the back surface (rear surface) of the flange portion 23 in the polymerization nozzle device 9, fitting holes 31A and 31B are formed, respectively, which can be fitted to the front end portions of the first and second cylinders 17A and 17B, respectively. The fitting of the fitting holes 31A, 31B and the cylinders 17A, 17B is performed densely via O-rings (not shown), and is integrally removed when the polymerization nozzle device 9 is removed from the cylinder support base 15. Is a relatively tight fit so that

  The polymerization nozzle device 9 has a double structure in which a cylindrical internal nozzle 35 is integrally fixed to a central portion of a hollow external nozzle 33, and a rotating body 39 having a gear 37 is provided at a lower portion. It is rotatable. The inner nozzle 35 and the fitting hole 31A communicate with each other through a communication hole 41A, and an annular passage 43 between the outer peripheral surface of the internal nozzle 35 and the outer nozzle 33 communicates with each other through a communication hole 41B. I have.

  As is understood from FIG. 3, the communication holes 41A and 41B are pressing surfaces of the first and second pistons 45A and 45B movably fitted in the first and second cylinders 17A and 17B. It is formed in a concave portion corresponding to the tapered surface 45T. In other words, the communication holes 41A and 41B are formed such that the side surfaces corresponding to the cylinders 17A and 17B in the overlapping nozzle device 9 are formed into tapered concave portions corresponding to the tapered surfaces 45T of the pistons 45A and 45B in the cylinders 17A and 17B. It is an embodiment formed.

  Therefore, the food material in each of the cylinders 17A and 17B is pushed out to the polymerization nozzle device 9 by the pistons 45A and 45B, and the tapered surfaces 45T of the pistons 45A and 45B engage with the tapered recesses of the communication holes 41A and 41B. This can reduce the amount of food material that remains and is wasted.

  In order to support the rear ends of the cylinders 17A and 17B in opposition to the fitting holes 31A and 31B in the overlapping nozzle device 9, a rear rising portion 47 is formed at the rear of the upper surface of the cylinder support base 15. The rear rising portion 47 has fitting support holes 49A and 49B for fitting and supporting the rear ends of the cylinders 17A and 17B.

  Further, there is provided a piston moving means for pressing and moving the pistons 45A and 45B in order to push out the food material in the cylinders 17A and 17B. That is, the nut members 51A and 51B are provided horizontally and rotatably on the rear surface of the rear rising portion 47 corresponding to the fitting support holes 49A and 49B, and the nut members 51A and 51B are provided with the rear portion. The threaded rods 53A and 53B as push operation members which penetrate the rising portion 47 in the front-rear direction and come into contact with the pistons 45A and 45B and can be pressed in the front direction (left direction in FIGS. 1 and 3) are movable in the front-rear direction. It is screwed into.

  In order to prevent the screw rods 53A and 53B from rotating, key holes 55A and 55B are formed in the screw rods 53A and 53B in the longitudinal direction. Lower ends of stoppers 57A and 57B supported by the portion 47 so as to be vertically movable are detachably engaged.

  To rotate the nut members 51A and 51B, gears 59A and 59B are formed on the outer peripheral surfaces of the nut members 51A and 51B, and the gears 59A and 59B are provided with endless belts such as chains and timing belts. The endless belts 61A, 61B are further wound around drive gears 65A, 65B provided in supply motors 63A, 63B (see FIG. 4) provided inside the frame main body 3. It is.

  With the above-described configuration, the nut members 51A and 51B are rotated forward and reverse by rotating the motors 63A and 63B in the forward and reverse directions, and the screw members 53A and 53B as the pressing operation members are moved in the front-rear direction (the left-right direction in FIGS. 1 and 3). ), The distal ends of the screw rods 53A, 53B abut against the pistons 45A, 45B in the cylinders 17A, 17B and move forward in the forward direction. During the backward movement, the distal ends of the screw rods 53A and 53B are separated from the pistons 45A and 45B, and only the screw rods 53A and 53B are retracted.

  By the way, as described above, the threaded rods 53A and 53B move forward, and the pistons 45A and 45B in the cylinders 17A and 17B reach the stroke ends and engage with the communication holes 41A and 41B, respectively. The food materials in 17A and 17B are pushed to the polymerization nozzle device 9 without waste. There is no problem if the pistons 45A and 45B in the cylinders 17A and 17B reach the stroke end almost simultaneously, however, depending on the difference in consumption of the food material, the food material remains in one cylinder, and the food material remains in the other cylinder. The other cylinder may need to be refilled with food material.

  Therefore, a sensor is provided for detecting that each piston 45A, 45B in each of the cylinders 17A, 17B has reached the stroke end. That is, in this example, as shown in FIGS. 1 and 3, a photoelectric sensor for detecting the passage of the rear ends of the screw rods 53A and 53B in the forward direction is provided at a position close to the nut members 51A and 51B. Appropriate sensors SA and SB such as switches, limit switches and proximity switches are provided.

  The sensors SA and SB detect the presence or absence of the screw rods 53A and 53B. As described above, the pistons 45A and 45B reach the stroke ends of the forward ends, and the rear ends of the screw rods 53A and 53B. Detects the rear end of the screw rod when passing through the position corresponding to each of the sensors SA and SB. Then, when at least one of the sensors SA, SB detects the rear end of the screw rod 53A, 53B, the driving of each of the motors 63A, 63B is stopped. Therefore, when each of the motors 63A and 63B stops, the missing cylinder is filled with food material.

  By the way, as a configuration for detecting that each piston 45A, 45B in each cylinder 17A, 17B has reached the stroke end, when each piston 45A, 45B reaches the stroke end and engages with each communication hole 41A, 41B, Since the load on each of the motors 63A and 63B suddenly increases, a configuration for detecting that the load on each of the motors 63A and 63B suddenly increases may be adopted.

  A motor base 67 is attached to the lower surface of the cylinder support base 15 via a bracket in order to rotate the rotating body 39 in the polymerization nozzle device 9, and an output shaft of a drive motor 69 supported by the motor base 67 is attached to the motor base 67. The mounted drive gear 71 is engaged with an intermediate gear 73 rotatably supported by a motor base 67. The intermediate gear 75 rotatably supported by the frame main body 3 and meshed with the gear 37 of the polymerization nozzle device 9 so as to be able to be disengaged from the intermediate gear 73 via a gear train 77 in which a plurality of gears mesh. Linked and linked.

  Therefore, by driving the drive motor 69, the gear 37 is rotated via the drive gear 71, the intermediate gear 73, and the gear train, and the rotating body 39 provided in the polymerization nozzle device 9 is rotated.

  As shown in FIG. 4, the wrapping cutting device 11 wraps and cuts the bar-shaped food 79 continuously discharged downward from the polymerization nozzle device 9 in a state where the inner wrapping material 79A is covered with the outer skin material 79B. For this purpose, a shutter mechanism is provided that is vertically movable and that is capable of opening and closing the passage of the bar-shaped food 79.

  More specifically, the envelope cutting device 11 is supported by upper ends of a pair of left and right lifting rods 83 guided vertically by a vertical guide member 81 (see FIG. 6) provided on the front surface of the frame body 3. The lower ends of the left and right lifting rods 83 are connected by a yoke member 85 as shown in FIG. The center of the yoke member 85 is pivotally connected to the distal end of a connecting plate 87 via a pivot 89. The base of the connecting plate 87 has an eccentric plate as a vertically moving cam fixed to a rotating shaft 91. 93 is rotatably fitted.

  As shown in FIG. 1, the rotating shaft 91 is horizontally and rotatably supported by the frame body 3. A bevel gear 95 attached to the base end of the rotating shaft 91 is driven by a motor 97 to reduce the speed. It is engaged with a bevel gear 101 attached to one end of the output shaft of the mechanism 99. Therefore, when the rotation shaft 91 is rotated by the motor 97, the envelop cutting device 11 is moved up and down via the eccentric disk 93 and the connecting plate 87.

  Further, as shown in FIG. 4, the shutter mechanism in the envelope cutting device 11 has a polygonal shape that is movable along each inner surface of a regular polygonal (a regular hexagonal in this example) opening formed in the casing 103. The shutter 105 is provided. As is well known, each shutter piece 105 opens and closes the shutter mechanism by moving each shutter piece 105 along each inner surface of the opening. A connecting pin 107 movably penetrating the casing 103 is fixed to the shutter piece 105.

  The head of the connecting pin 107 is integrally fixed to a slide shaft 109 orthogonal to the connecting pin 107. As shown in FIG. 4, the slide shaft 109 is supported by a guide portion 111 provided in the casing 103 in a front-rear direction so as to be movable back and forth. As shown in FIG. 5, a rear end of the slide shaft 109 is connected to a guide member 113 provided on the frame main body 3 at substantially the same height so as to be movable back and forth. 117 is connected to be movable up and down relatively.

  More specifically, the connecting member 117 has a U-shape or an annular shape, and a vertical slit 117S is formed on the front surface, and the rear end of the slide shaft 109 is relatively formed in the slit 117S. , But are engaged so as to move integrally in the front-rear direction. Note that the connection member 117 may be connected to one of the slide shafts 109 and 115 as appropriate, since it is relative.

  In order to open and close the shutter mechanism by moving the slide shaft 115 back and forth, a shutter opening / closing cam 119 is provided to be horizontally rotatable, as shown in FIG. A cam follower engaged with a cam groove 119G formed in the cam 119 is provided at an intermediate portion of a swing lever 123 whose base end is pivotally supported by the frame body 3 via a hinge pin 121 and is swingable in the front-rear direction. 125 are provided. Further, one end of a link 129 is pivotally connected to the tip of the swing lever 123 via a pin 127, and the other end of the link 129 is connected to the rear end of the slide shaft 115 via a pin 131. It is pivotally connected to the department. The cam 119 is integrally mounted on the other end of the output shaft of the speed reducer 99, and rotates integrally with the bevel gear 101.

  With the above configuration, the cam 119 is rotated by driving the motor 97, and the rotation of the cam 119 causes the swing lever 123 to swing in the front-rear direction, thereby moving the slide shaft 115 back and forth. Then, the slide shaft 109 is moved back and forth via the connecting member 117, the shutter piece 105 of the shutter mechanism is moved, and the opening and closing operation of the shutter mechanism is performed. The wrapping of the bar-shaped food is cut by opening and closing the shutter mechanism.

  As already understood, the opening and closing operation of the shutter mechanism in the envelope cutting device 11 and the vertical movement of the envelope cutting device 11 are operated in association with each other, and a slide shaft 109 and a slide shaft for opening and closing the shutter mechanism are operated. Reference numeral 115 denotes a configuration that moves in the same direction at substantially the same height, and is arranged in a range in which the up-and-down movement of the envelope cutting device 11 is allowed. It can be held with a small size, and there is no delay in the opening and closing operation of the shutter mechanism. Cutting can be performed.

  As shown in FIGS. 1 and 2, the food receiving member 13 that receives the wrapped food cut and wrapped by the wrapping and cutting device 11 is vertically movable to a position below the wrapping and cutting device 11 and forward. It is arranged to be free to tilt.

  More specifically, a pair of left and right upper and lower guide members 133 is provided at a lower portion on the front side of the frame body 3, and an upper and lower slider 135 is provided between the upper and lower guide members 133 so as to be vertically movable. A swing member 141 is supported on the upper part of a bracket 137 provided on the front surface of the vertical slider 135 via a pin 139 in the left-right direction so as to be vertically rotatable. 1 is urged clockwise in FIG. 1 via a spring (not shown), and the rear end side of the swing member 141 contacts the upper surface of the upper and lower slider 135 to be held substantially horizontally.

  The food receiving member 13 is supported by a rising flange 141F formed on one side of the swing member 141 so as to be vertically adjustable. That is, a vertical plate 143 vertically extending from the food receiving member 13 is formed with a vertical slit 145, and a fixing member 147 such as a bolt or a nut penetrating the slit 145 allows the vertical member 143 to be fixed to the swing member 141. The food receiving member 13 is supported so as to be vertically adjustable.

  In order to move the vertical slider 135 up and down, a cam groove 149 of an appropriate shape is formed in the vertical slider 135, and the cam groove 149 has a tip end of a lever 151 attached to a tip end of the rotary shaft 91. Are engaged.

  With the above configuration, when the rotation shaft 91 rotates counterclockwise in FIG. 2, the cam follower 153 rotates counterclockwise from the top dead center position, and initially rotates along the cam groove 149. The slider 135 has a state in which the upper surface of the cam groove 149 is supported by the cam follower 153, and the upper and lower sliders 135 are in a state of being held at the highest position.

  When the rotation shaft 91 rotates counterclockwise by about 90 ° and the cam follower 153 contacts the lower end of the cam groove 149, the upper and lower sliders 135 are gradually lowered. When the vertical slider 135 descends, the rear end side of the swing member 141 comes into contact with the upper portions of the left and right vertical guide members 133, and then the vertical slider 135 further descends, and the swing member 141 moves about the pin 139 in FIG. Then, it turns counterclockwise against the urging force of the torsion spring and tilts so that the front side becomes lower. Therefore, the food receiving member 13 also inclines so that the front side becomes lower, and the wrapped food (not shown) received on the upper surface falls to the front side.

  Thereafter, when the cam follower 153 gradually rises after passing through the bottom dead center, the cam follower 153 gradually moves from the lower end side of the cam groove 149 to the upper end side, and gradually raises the vertical slider 135. Therefore, the swinging member 141 gradually returns to the original state by the action of the torsion spring, and returns to the original state as shown in FIGS. 1 and 2 when the cam follower 153 returns to the top dead center.

  As already understood, since the lever 151 for vertically moving the food receiving member 13 is attached to the rotating shaft 91 to which the eccentric disk 93 is attached, the lever 151 operates in association with the vertical movement of the envelope cutting device 11. It will move up and down and tilt forward. Therefore, it is possible to receive the wrapped food cut and wrapped by the wrapping and cutting device 11 and discharge the wrapped food to the front side with good timing.

  Depending on the properties of the food material, as shown by the imaginary line in FIG. 1, the food receiving member 13 is provided with a box-shaped attachment AT having an appropriate structure containing appropriate powder such as hand flour, and It is desirable to adopt a configuration that prevents adhesion or adhesion to the receiving member 13.

  As can be understood from the above description, when removing the polymerization nozzle device 9, the cylinders 17A and 17B can also be removed integrally from the cylinder storage portions 16A and 16B with the pistons 45A and 45B installed. The food material does not leak out from between the cylinders 17A and 17B and the polymerization nozzle device 9, and does not stain the surroundings. Further, as described above, since the polymerization nozzle device 9 and the cylinders 17A and 17B can be detached, the polymerization nozzle device 9, each of the cylinders 17A and 17B, and the pistons 45A and 45B can be easily cleaned, and the cleaning can be performed. Later, after the pistons 45A, 45B are fitted into the cylinders 17A, 17B, food materials can be filled into the cylinders 17A, 17B in a detached state, and the filling operation can be easily performed.

  Furthermore, after removing the polymerization nozzle device 9 and the cylinders 17A and 17B, for example, it is also possible to mount a separate polymerization nozzle device and a cylinder previously filled with food material, and to set an inner packaging material and an outer skin material of different food materials. Can be performed quickly, and high-mix low-volume production can be performed efficiently.

  After the cylinder 17A, 17B is filled with food material and stored in each of the cylinder storage sections 16A, 16B and attached, the pistons 45A, 45B in the cylinders 17A, 17B are pressed by the pressing operation members 53A, 53B. Since the food material is extruded, kneading and stirring of the food material are suppressed. Finally, the food material is pushed out such that the tapered surfaces 45T of the pistons 45A and 45B are aligned with the communication holes 41A and 41B of the polymerization nozzle 9, so that the remaining amount of the food material can be reduced. .

  When the cylinders 17A and 17B are attached and detached as described above, since the grooves 15G are formed in the left and right walls 15A and 15B of the cylinder housings 16A and 16B, when the respective cylinder housings 16A and 16B are cleaned. It is easy to drain and can be cleaned efficiently.
