[Detailed explanation of the idea]

<Industrial Application Field> The disclosed technology belongs to the field of soft material leakage prevention seal structure technology for a feeding device for a molding machine for forming soft materials such as the contents of foods such as dumplings and shumai. <Summary of the gist> This invention is based on a device that is connected between a feeding device such as a plunger installed at the lower supply port of a hopper for feeding the stuffing of shumai, gyoza, etc., and a molding machine. This invention relates to a food soft material feeding device in which a seal for soft materials such as meat paste is provided between the casing of an interposed embossing piston and a feeding plunger, and in particular, the above seal is This invention relates to a food soft material feeding device consisting of a nozzle facing a bore between a casing and a plunger, and a compressed gas source such as compressed air connected to the nozzle via a passage such as a hose. be. <Prior Art> As is well known, the food industry has improved considerably, and there is a strong need to improve the quality and lower the cost of many products in the distribution market. Among the popular mass-produced food supplies are foods such as gyoza and shyu mai, which are wrapped in noodle strips filled with paste, etc.
These foods consist of two types: noodle strips and soft materials such as paste meat, but noodle strips are pre-mass-produced and molded.
The dough is generally formed through a forming process in which the dough is fed in fixed amounts from a hopper to the noodle strip fed from a pressure feeding device such as a plunger. As shown in FIG. 3, the feeding device for soft materials such as dough into the molding process supplies the soft materials to a hopper 1, and a gear pump device 2 passes the soft materials through a reciprocating pressure feeding device 3 to the mold. After the noodle strips 6, which have been previously formed and fed into the forming device 5 provided at the lower part of the pushing piston 4 and are fed to the pushing piston 4, are primarily formed by the pushing piston 4, the plunger 7 is pushed forward to push the soft material of the dough into the noodle band 6 to form it, and then feed it to the next stage to perform continuous forming. <Problem to be solved by the invention> As shown in FIG. In order for the softwood dough 8 to leave the hopper 1 through the respective supply devices 2 and 3 and be pushed from the embossing piston into the noodle strip 6 by the plunger 7, the reciprocating action of the plunger 7 against the embossing piston 4 in the final feeding process is required. There is a risk of slight flesh leakage. Therefore, to deal with this, as shown in Figure 4,
The plunger 7 connected to the air cylinder 9 or the like with respect to the embossing piston 4 is connected to the plunger 7 and the bore 11 in order to reciprocally slide in a bore 11 formed in the casing 10 of the embossing piston 4.
A rubber seal ring 12 is interposed in the plunger 7 to prevent the paste from leaking from the minute clearance between the casing 1 and the casing 1.
An O-ring is inserted on the 0 side. However, in this type of seal mechanism, if the rubber seal ring is used, it is inevitable that it will wear out over time, and therefore, there is a drawback that leakage basically occurs, and in the case of the O-ring, However, although the length of time may vary, the basic problem of leakage due to wear is unavoidable, and therefore, the embossing piston 4 and plunger 7 are often disassembled. Seal ring 1
2 and O-rings have to be replaced, which is a cumbersome process, and the line has to be stopped during that time, resulting in an unavoidable drop in efficiency. In addition, both the seal ring 12 and the O-ring have the drawback that due to the above-mentioned wear over time, there is a risk that even a very small amount of abrasion powder may be mixed into the soft material. Meat leaks from the feeding cylinder not only contaminates the area around the feeding cylinder, which is not good for food hygiene, but also easily contaminates the working environment, which requires unnecessary labor to clean up. There was a negative point that it also came with. The purpose of this invention is to solve the problem of seals that deal with meat leakage when supplying soft materials such as dough to noodle sheets etc. based on the above-mentioned conventional technology, and to solve the problem of seals that deal with meat leakage when feeding soft materials such as dough to noodle sheets etc. Although it is assumed that there is a small gap between the bore and the plunger, it reliably prevents meat leakage, and also eliminates the need to stop the equipment due to equipment maintenance, inspection, maintenance, and replacement. It is an object of the present invention to provide an excellent soft material feeding device for food that is useful for molding applications in the food industry without causing any problems in terms of food hygiene. <Means/effects for solving the problem> In accordance with the above-mentioned purpose, the structure of this invention, which is summarized in the scope of the above-mentioned utility model registration claim, is to solve the above-mentioned problem. The soft wood is fed through an agitator to an embossing piston facing a forming device from a plunger-type feeding device, etc., and the embossing piston primarily forms noodle strips etc. into a specified shape, and then the plunger for the embossing piston The embossing piston reciprocatingly slides against the bore in the casing, and the soft material such as dough fed by the above-mentioned pressure feeding device is fed in a fixed amount from inside the embossing piston to the noodle strips, etc., and repetitive work is performed. Therefore, air etc. from a compressed gas source is fed to the bore from a nozzle facing the bore of the casing of the feeding cylinder to prevent leakage such as flesh leakage from between the bore and the plunger, and This is a technical measure that reduces the friction in the reciprocating slide between the casing and plunger, creates a kind of fluid bearing action, and prevents wear between the casing and plunger. . <Embodiment - Configuration> Next, one embodiment of this invention will be described below based on FIGS. 1 and 2. Furthermore, 3rd and 4th
Components having the same features as those in the drawings will be described using the same reference numerals. Reference numeral 13 denotes a food soft material feeding device which constitutes the gist of this invention, and in this embodiment, it is used to supply a fixed amount of the paste meat to the skin of dumplings, and inside the hopper 1 there is a device (not shown). A stirring screw type agitator 14 connected to a rotary drive mechanism similar to the conventional one is provided, and the lower part of the agitator 14 faces a gear pump 2 of a fixed quantity feeding device connected to the hopper 1. A lower part of the gear pump 2 is connected to a supply passage 16 provided in a casing 15 of the pressure feeding device 3. A rotary solenoid (not shown) is connected between the front feeding passage 17 and the rear feeding passage 18 provided in the axial direction of the casing 15 of the pressure feeding device 3, and between the feeding passage 16. A three-way switching valve 19 is provided to intermittently cut off the supply of the dough from the gear pump 2 to the embossing piston 4 at the next stage. A plunger 20 is fitted into the rear feeding passage 18 of the pumping device so as to be able to move forward and backward, and is connected to an appropriate reciprocating drive mechanism 21. And the stamped piston 4 is attached to the casing 1
A plunger 7 is provided in a bore 11 formed in the bore 11 so as to be slidable up and down.The plunger 7 can be moved up and down with a predetermined stroke by an air cylinder 9.
lowers the plunger 7 during the initial stroke, and then the ring-shaped bracket 24 fixing the stamped piston 4 to its ram 23 and the base frame.
The gyoza noodle strip 6 is intermittently fed in advance to the forming device 5 formed at the lower end by pressing down a predetermined stroke against the elastic spring 25 interposed between the It is made to be molded. The bore 11 formed inside the ram 23 of the embossing piston 4 and the casing 15 of the pressure feeding device 3
A connecting passage 26 is formed between the feeding passage 17 and the front part of the feeding passage 17 . The above-described structure is substantially the same as the conventional food soft material feeding apparatus shown in FIGS. 3 and 4. Accordingly, in this invention, as shown in FIG.
A seal 12' is formed opposite the bore 11. As shown in FIG. 2, the seal 12' is
A nozzle 27 for the bore 11 is formed, and is connected by a nipple 28 to a compressed air source 31 as a source of compressed gas at a predetermined pressure via a passage 29 such as a hose and an electromagnetic valve 30, and compressed air is supplied from the nozzle 27 into the bore 11. It is designed to be ejected. Therefore, the casing 1 of the stamped piston 4
Even if the plunger 7 relative to 0 slides in a reciprocating manner within the bore 11, high-pressure compressed air is always ejected into the minute clearance formed within the bore 11 and acts as a seal, so that it is not supplied from the passages 17 and 26. There is no risk of the dough leaking from the bore 11 to the outside of the casing 10, that is, to the outside of the embossing piston 4. The operation of the gear pump 2, the three-way valve 19, and the air cylinder 9, as well as the feeding and unloading of the gyoza noodle strips 6 to the forming device 5, are controlled by a control device (not shown) in a set cycle via a set sequence. has been done. 〓Example - Effect〓 In the above-described configuration, when the hopper 1 is supplied with soft wood as the dough of gyoza, and the noodle strip 6 of gyoza skin is intermittently fed to the forming device 5 and taken out, the inside of the hopper 1 is The supplied dough is uniformly stirred and kneaded by the agitator 14, fed from its lower part to the gear pump 2, quantitatively fed intermittently, and fed to the three-way valve 19 from the feed passage 16. As shown in FIG. 1, when the plunger 20 is moved backward by the reciprocating drive mechanism 21 via the control device as described above, the soft material dough 8 kneaded by the gear pump 2 is sent by the three-way valve 19. The three-way valve 19 blocks the feed passage 17 to the embossing piston 4 side (substantially due to the continuous operation, the feed passage 17 is supplied with pressure and suction). The gear pump 2 is stopped via the control device and the three-way valve 19 is rotated 90 degrees to the left in the figure, so that the feed passage 18 is closed to the three-way valve. Feed passage 1 via 19
7, and when the plunger 20 is advanced by the reciprocating drive mechanism 21, the feed passage 1
8. Apply pressure to the three-way valve 19 and the dough 8 in the feed passage 17, and press the mold into the inside thereof via the feed passage 26 of the ram 23 of the embossing piston 4 connected in the illustrated state. The bore 11 is about to become starved as the plunger 7 of the push piston 4 rises.
The paste 8 is pumped and filled into the inside, and all the passages 16, 17, 18, 19, 26 and the bore 11 are filled with pressure.
The plunger 7 is lowered into the bore 11 in the casing 10 of the feed cylinder of the embossing piston 4 via the control device or by retraction of the cylinder 9 when the inside is filled with the dough 8. As a result, the dough 8 filling the feeding passage 26 and the bore 11 is transferred from the tip of the embossing piston 46 to the upper part of the forming device 5 into the primarily formed noodle strip 6 as shown by the arrow. Fall filling. After the drop-filling, the feeding device (not shown) of the forming device 5 feeds the noodle strips 6 filled with the dough 8 to the next forming device via the control device. The noodle strip 6 is carried into the upper part of the forming device 5. At that timing, the upper connecting connector 22 of the air cylinder 9 finishes the stroke of the plunger 7 against the embossing piston 4 and comes into contact with the upper part of the embossing piston 4, pushing the embossing piston 4 further against the elastic spring 25. Molding device 5
The noodle strips 6 being carried in are brought into close proximity to the upper part of the noodle strips 6 as shown in the figure, and then the air cylinder 9 is raised by the double action of the plunger 7 by the control device 2, and the embossing piston 4 is moved by the elastic spring. The plunger 7 rises due to the elastic force of the embossing piston 4 and returns to its initial position, and the plunger 7 further rises to the upper fulcrum relative to the embossing piston 4 and returns to its initial position, returning to the initial position and moving inside the bore 11 in the ram 23 of the embossing piston 4. The paste 8 tends to be missing as described above, but as described above, by rotating the three-way valve 19 to the left in the figure, the three-way valve 19, the feeding passage 17, and the ram 23 are fed through the plunger 20. The dough 8 in the supply passage 26 receives a pressing force, feeds and fills the amount of dough 8 that is about to be missing in the bore 11, returns to the initial position, and thereafter is fed intermittently in the same manner. The soft material of the dough 8 is supplied to the noodle strip 6 in a cyclical manner. In this way, no vacuum is created in any of the passages, and the dough 8 is always kept in a full feeding position. The above-mentioned process is the same as the conventional method shown in FIG. The dough 8 supplied from the feed passage 26 tends to leak during operation, but in this invention, the compressed air from the compressed air source 31 flows into the bore 11 from the nozzle 27 provided facing the inside of the bore 11. Since the dough is constantly sprayed and filled under high pressure, the dough 8 that tends to leak from the inside of the feed passage 26 and the bore 11 to the upper end of the embossing piston 4 comes under pressure and is prevented from leaking. In addition, in the reciprocating process for the bore 11 of the plunger 7, a kind of air floating effect is performed, and a fluid bearing function is achieved, the sliding resistance is reduced, and the O-
Reciprocating slides can be performed smoothly without intervening a ring or the like. It goes without saying that the embodiment of this invention is not limited to the above-mentioned embodiment. For example, compressed air may be used to supply the compressed gas to the seal to prevent meat leakage, but in order to avoid deterioration of the quality of the dough, etc. An inert gas such as nitrogen gas may be supplied, or a mist of edible oil such as salad oil may be mixed to season the paste and lower the sliding resistance of the plunger 7 against the inside of the casing. In that case, the edible oil mist leaking from the bore 11 will not substantially cause any harm to the food. When producing shumai, an experiment was conducted to determine the amount of meat leakage in kilograms per machine between the conventional equipment shown in Fig. 3 and the embodiment of this invention regarding the supply of dough for shumai meat as the filling. The data are shown in Table 1.

[Table] In this way, compared to the case where no reduction rate could be obtained with the conventional device, this invention prevented flesh leakage to a level of 85%, which is essentially a state where there is no actual damage. Further, the compressed air for sealing in precision measurement is as shown in Table 2.

[Table] From the data shown in Table 2, it was found that as the pressure of compressed air was increased, the amount of flesh leakage could be suppressed to the limit. In addition, the soft material of the food to which this invention is applied is not only the stuffed meat of gyoza, but also the filling of shumai, and of course, it can also be applied to the filling of steamed buns, cakes, etc. It is. <Effects of the invention> According to this invention, basically, the most effective method for a molding device is to feed a soft material such as dough to a noodle strip such as gyoza skin through a plunger to an embossing piston. The soft material such as dough, which is fed through the unavoidable minute clearance of the bore formed between the casing of the embossing piston and the plunger, which is located close to each other, is put under pressure by the compressed gas and becomes meat. An excellent effect is achieved in that no leakage occurs, and therefore, leakage of pasted meat etc. does not adhere to the embossing piston etc. and rot, and it can be removed or
Work such as wiping is unnecessary, unnecessary work is omitted, and the work environment is maintained in a normal state, which is an excellent effect. In addition, since compressed gas is supplied to the bore between the embossing piston and the plunger, abrasion particles such as seals and O-rings for soft materials such as pasted meat do not get mixed in, and food It has the excellent effect of achieving perfection in terms of hygiene. Furthermore, since the frictional resistance of the reciprocating slide of the plunger against the casing is reduced by a type of fluid bearing, there is also the advantage that power costs can be reduced. In addition, a design that mixes a mist of salad oil, etc. into the compressed gas has the excellent effect of not only seasoning the soft wood of the meat paste, but also reducing the sliding resistance of the plunger against the casing. be done.
