Description

  The present invention relates to an apparatus used for producing noodles (raw noodles) such as buckwheat noodles, udon, ramen, etc., and in particular, an extrusion noodle making machine for producing elongated linear noodles from previously made lump dough About.

  Generally, noodles such as buckwheat noodles, noodles, ramen, etc. are mixed with raw flour such as buckwheat flour and wheat flour, kneaded to make a lump noodle dough, then stretch the lump noodle dough flatly and cut it into elongated pieces Made by

  Noodles obtained by performing the above process by hand are called hand-made noodles, but noodle making machines that can efficiently produce large quantities of noodles by automating such processes have been widely used in the past. ing.

  As such a noodle making machine, there are known ones that can consistently carry out the process from the production of noodle dough to cutting, and the one that performs the noodle dough production process and the subsequent processes separately.

  However, many of the conventional apparatuses have a problem that the structure of the apparatus becomes complicated because the rolling part is provided in the previous stage of the cutting part in connection with the final cutting of the noodle dough.

  In addition, when the rolled noodle dough is cut into a long and narrow shape, there are problems that a large amount of chips are generated and it is difficult to manufacture a cutting blade.

  Thus, there is known an extrusion type noodle making machine in which an noodle dough obtained by an automatic machine or a manual work is not rolled and cut, but is extruded to obtain a linear noodle (raw noodle).

  As such an apparatus, a mounting table for mounting a receiving container for receiving the noodles to be extruded, a main housing part arranged at a predetermined distance above the mounting table, and the main housing A molding die member that is detachably mounted on the side of the part facing the mounting table, and a molding actuating member that is attached to a side opposite to the side on which the molding member of the main housing part is mounted. The mold member is provided with a molding cylinder having an opening on the side of the main housing portion and having a bottom portion having a number of thin through holes on the side of the mounting table. A molding piston that is inserted into and removed from the opening in the molding cylinder of the molding die member, and a drive unit for driving the insertion and removal of the molding piston are provided, and a predetermined amount is kneaded into the molding cylinder. The molding die member containing the material is put in the inserted state, the driving unit is operated to insert the molding piston into the molding cylinder, and the raw material is pressed to the bottom, thereby allowing the mounting table to pass through a large number of thin through holes. A noodle extruding machine has been proposed in which noodles extruded to the end are served (Patent Document 1).

JP-A-8-294350

  However, according to the extrusion-type conventional apparatus as disclosed in Patent Document 1, the barrel (molding cylinder) can be continuously formed into a linear shape without rolling and cutting the massive noodle dough. Since the cylinder has the same inner diameter over its entire length, when a single-action cylinder is used to drive the piston and the return operation is performed by a spring force, the noodle dough is pushed out by the piston that descends in the barrel. After that, the piston sometimes stopped halfway during the return to ascending.

  In other words, when the noodle dough is pushed out, the piston smoothly moves down the barrel while pushing out the noodle dough. Therefore, if it is attempted to raise the piston in this state, a large negative pressure is generated in the barrel, and a downward force opposite to the upward force acts on the piston.

  In order to ensure that the piston is lifted and returned reliably, a large lifting return force may be applied to the piston using a double-acting fluid pressure cylinder or the like, but this requires an increase in the size of the drive unit. In addition, there is a problem that energy consumption increases and noodle making costs increase.

  The present invention has been made in view of the circumstances as described above, and its purpose is an extrusion-type noodle making machine capable of efficiently producing noodles from a lump-shaped noodle dough without the phenomenon that the piston does not return to the upper side. Is to provide.

  In order to achieve the above-mentioned object, the present invention provides a nozzle plate having a plurality of extrusion holes, a cylindrical barrel having the nozzle plate at the bottom and an upper end opening serving as an inlet for noodle dough, And a piston for extruding noodle dough supplied into the barrel from the inlet through each extrusion hole of the nozzle plate, and the barrel is on the nozzle plate side A main pressurizing chamber in which the inner diameter of the arbitrary cross section is the same, and a pressure adjusting chamber in which the inner diameter gradually increases toward the charging port side of the noodle dough continuously above the main pressurizing chamber. An air gap is formed around the piston in the pressure adjusting chamber, and the piston moves up and down while sliding on the entire inner wall of the main pressurizing chamber.

  Further, in the extrusion type noodle making machine as described above, the piston has a conical shape in which the bottom surface facing the nozzle plate has a larger area than the top surface, and the bottom periphery of the piston is the main pressurizing chamber when the noodle dough is extruded. It is characterized by being in sliding contact with the entire inner wall of the.

  According to the extrusion-type noodle making machine according to the present invention, the barrel is on the nozzle plate side and forms a main pressurizing chamber having the same inner diameter of an arbitrary cross section, and a piston is provided around the inner wall of the main pressurizing chamber. Since it moves up and down while sliding, the noodle dough in the barrel can be favorably pushed out from each extrusion hole of the nozzle plate without flowing back upward when the piston is lowered.

  In particular, in the upper part of the main pressurizing chamber, a pressure adjusting chamber whose inner diameter is gradually set larger toward the noodle dough inlet side is formed in the barrel, and a void is formed around the piston in the pressure adjusting chamber. For this reason, when the piston reaches the pressure adjusting chamber from the main pressurizing chamber after the noodle dough has been extruded, the outside air can be allowed to flow from the pressure adjusting chamber into the main pressurizing chamber through a gap formed around the piston.

  For this reason, the pressure difference between the main pressurizing chamber and the pressure adjusting chamber is eliminated at an early stage. Therefore, even if a single-action cylinder is used for the lowering operation of the piston and the piston is raised and returned by a spring force, the piston is not in the middle of the upward movement. Even when the piston is moved up and down by a double-acting cylinder or the like without falling into an operating state, the driving force required for returning and raising the piston can be reduced to reduce the size and energy of the drive unit.

  In addition, since the piston has a conical shape having a bottom area larger than the top surface, the piston can be smoothly moved up and down in the main pressurizing chamber.

  Hereinafter, an extrusion noodle making machine according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic side view showing the noodle making machine, and FIG. 2 is a schematic front view showing the noodle making machine. 1 and 2, 1 is a main body of the noodle making machine, 2 is an operation part provided at the upper front of the main body of the noodle making machine. An extrusion part 3 for obtaining is provided.

  The extrusion molding unit 3 includes a seat plate 32 that is supported horizontally via a support shaft 31 that hangs down below the operation unit 2, a cylindrical barrel 33 that is fixed to the seat plate 32, and a barrel 33 And a corresponding piston 34 that can be moved up and down, and the piston 34 is moved up and down by the drive unit 4.

  The drive unit 4 is composed of a hydraulic device including a hydraulic pump 41 built in the noodle making machine body 1 and a hydraulic cylinder 42 driven by hydraulic oil fed from the hydraulic pump 41. The piston 34 is fixed to the tip of the rod 42A. In this example, the hydraulic cylinder 42 is a single acting type in which the cylinder body 42B is fixed in the operation section 2 with the rod 42A facing downward, and the contraction operation of the rod 42A (the upward movement of the piston 34) is performed by the hydraulic cylinder 42. This is performed by a spring (not shown) provided in the cylinder body 42B.

  Further, operation switches such as a push button and a main power switch for operating the hydraulic cylinder 42 are provided on the front surface of the operation unit 2.

  Next, the structure of the extrusion molding portion will be described with reference to FIG. 3. The seat plate 32 is a plate material that forms a U-shaped cutout portion 32 </ b> A that receives the barrel 33. Connected one by one. A pair of left and right side guides 35 are fixed to the upper surface of the seat plate 32 with the notch 32A interposed therebetween. In particular, the pair of side guides 35 cuts out opposite inner corner portions to form a U-shaped guide groove 35 </ b> A between the pair of side guides 35 and the seat plate 32.

  On the other hand, the barrel 33 has an upper end opened as a noodle dough inlet 33A, and a ring-shaped flange 36 is integrally formed at the upper end. In FIG. 3, reference numeral 37 denotes a slide plate to which the barrel 33 is assembled. The slide plate 37 is formed with a circular opening 37 </ b> A that supports the flange 36 integral with the barrel 33. The slide plate 37 is a plate that is slidable along the guide groove 35A. When the slide plate 37 is fitted into the guide groove 35A, both side edges of the slide plate are sandwiched between the seat plate 32 and the side guide 35, and a flange 36 is provided. The vertical movement of the barrel 33 is regulated by the side edges of the lens 33 entering the guide groove 36A.

  In particular, the barrel 33 and the piston 34 face each other at a position where the barrel 33 reaches the rearmost portion of the cutout portion 32A, and the lowering movement of the piston 34 into the barrel 33 is allowed. The slide plate 37 is fixed by a fixing screw 38 so that the barrel 33 and the piston 34 can be kept opposite to each other.

  Reference numeral 37B denotes a handle fixed to the front end surface of the slide plate so that the slide plate 37 can slide along the guide groove 35A. A lump of noodle dough can be introduced and supplied into the barrel 33.

  Next, FIG. 4 shows a longitudinal section of the barrel. As is apparent from this figure, a nozzle plate 39 is provided at the bottom of the barrel 33, and this nozzle plate 39 (die) is screwed to the barrel 33. As shown in FIG. 5, the nozzle plate 39 is a circular plate having a plurality of extrusion holes 39A formed in the thickness direction, and the lump noodle dough is continuously formed as linear noodles through each of the extrusion holes 39A. Extruded. In this example, the nozzle plate 39 is detachable from the barrel 33 as a replacement part. However, it may be formed integrally with the barrel 33.

  Further, as is apparent from FIG. 4, the barrel 33 forms a main pressurizing chamber R1 and a pressure adjusting chamber R2 in the inside thereof continuously in the vertical direction. The main pressurizing chamber R <b> 1 is a cylindrical hollow region whose inner diameter of an arbitrary cross section is the same (74 mm in this example) on the nozzle plate 39 side, and its height is about half of the total height of the barrel 33.

  On the other hand, the pressure adjusting chamber R2 is a tapered hollow region whose inner diameter is set continuously larger toward the noodle dough inlet 33A side (upper end opening) continuously from the upper portion of the main pressurizing chamber R1. The small diameter matches the inner diameter of the main pressurizing chamber R1, and the maximum diameter is the noodle dough inlet 33A (76 mm in this example). The inside of the flange 36 formed integrally with the upper end of the barrel 33 is a tapered hole having a taper larger than that of the pressure adjusting chamber R2.

  According to the present invention, when the piston 34 is moved up and down in the barrel 33, the pressure adjustment chamber R2 is located around the piston 34 (between the inner wall of the pressure adjustment chamber R2 and the piston 34) in the pressure adjustment chamber R2. Is formed between the main pressurizing chamber R1 and the main pressurizing chamber R1, and the piston 34 is in sliding contact with the entire inner wall of the main pressurizing chamber R1.

  Therefore, when the noodle dough in the barrel 33 is pushed out from the respective extrusion holes 39A of the nozzle plate 39 by the piston 34, the noodle dough in the main pressurizing chamber R1 is not allowed to flow back into the pressure adjusting chamber R2, and the nozzle plate 39 Each extrusion hole 39A can be pushed out, and after extrusion of the noodle dough, the bottom 34A reaches the pressure adjusting chamber R2 and the outside air flows into the main pressurizing chamber R2 from the periphery of the piston 34 so that the piston 34 has a small external force. Can be returned to the ascending end.

  4 and 6, the piston 34 has a bottom surface 34A (head surface) facing the nozzle plate 39 having a conical shape having a larger area than the upper surface 34B, and the peripheral edge of the bottom surface 34A having the maximum area. Only is in sliding contact with the entire inner wall of the main pressurizing chamber R1. Therefore, the piston 34 in the main pressurizing chamber R1 can be smoothly raised and lowered under a small frictional resistance.

  Here, the operation of the noodle making machine configured as described above will be described. In order to produce linear noodles using such a noodle making machine, first, the slide plate 37 is withdrawn to the front, and a lump of noodle dough that has been kneaded in advance is supplied into the barrel 33 from the inlet 33A. Next, after the slide plate 37 with the barrel 33 is returned to the original position, the operation unit 2 is operated to supply hydraulic oil to the bottom side of the hydraulic cylinder 42.

  Then, the rod 42A of the hydraulic cylinder extends, and the piston 34 fixed to the lower end thereof enters the barrel 33 and descends in the barrel 33 while compressing the noodle dough. When the piston 34 reaches the main pressurizing chamber R1 from the pressure adjusting chamber R2, the noodle dough is pushed out from each extrusion hole 39A of the nozzle plate as a linear noodle m. When the piston 34 reaches the position of the nozzle plate 39, this is detected by a sensor (not shown), and the supply of hydraulic oil to the hydraulic cylinder 42 is thereby stopped.

  As a result, the hydraulic oil is pushed out from the hydraulic cylinder 42 while the rod 42A of the hydraulic cylinder is moved upward by the elasticity of the spring (not shown), and the movement of the piston 34 is converted to the upward movement along with this, but the piston 34 Although the restoring force of the spring is large at the initial stage when the increase of the pressure starts, the spring force gradually decreases, and the negative pressure in the main pressurizing chamber R1 gradually increases.

  Here, before the negative pressure in the main pressurizing chamber R1 to lower the piston 34 exceeds the lifting force of the piston 34 by the spring, the piston 34 leaves the main pressurizing chamber R1 and is in the pressure adjusting chamber R2. It is supposed to reach up to.

  For this reason, when the piston 34 reaches the pressure adjusting chamber R2, the outside air flows into the main pressurizing chamber R1 from the periphery, and the pressure difference between the main pressurizing chamber R1 and the pressure adjusting chamber R2 disappears, and the piston 34 is stopped halfway. It will return to the initial rising edge without doing.

  Although the present invention has been described above, the drive unit 4 is not limited to a hydraulic device, and a pneumatic cylinder or an electromagnetic solenoid can be used as an actuator instead of the hydraulic cylinder 42, and a rotary actuator such as an electric motor can be used. It is also possible to convert the rotational driving force into a lifting / lowering motion of the piston 34 by a link mechanism.
