Description

  The present invention relates to a forming apparatus for forming a small lump of kneaded raw material into a spherical shape, for example, in a manufacturing process of fish meat or livestock meat paste products.

  When mass-producing and manufacturing spherical kneaded products using fish meat, livestock meat, etc. as raw materials, the kneaded raw materials obtained by mixing and adjusting the raw materials are subdivided into raw material chunks corresponding to individual products, and each raw material lump is shaped into a predetermined shape. After the molding, the process of heat treatment to obtain the final form of the product is continuously performed.

  In such a continuous process, a molding apparatus is placed in the middle of a path on which a plurality of raw material lumps obtained by dividing a kneaded raw material into a predetermined amount on a belt conveyor are placed in parallel at predetermined intervals and conveyed to a heat treatment apparatus. The raw material block is formed into a spherical shape for each row.

  As the spherical molding device, a device having a mechanism for lowering a molding die for receiving the raw material chunks sequentially and continuously conveyed by the belt conveyor after being lowered for a certain time on the belt conveyor is proposed (for example, Patent Document 1). In this molding die raising / lowering molding apparatus, each raw material lump received at the contact portion of the molding die is formed into a round shape by being rolled for a certain time by the action of a biasing force in the conveying direction. .

  In addition to such a mold raising / lowering method, for example, a pulley in which a plurality of grooves having a semicircular cross section are formed, and a plurality of circular arc-shaped concave portions that form a hollow tube having a circular cross section in cooperation with the grooves. There has also been proposed a molding apparatus that includes a formed guide member and continuously obtains a spherical raw material by passing a kneaded raw material through a hollow tube while rotating a pulley (see Patent Document 2). However, with such a pulley rotation method, the apparatus itself is large and complicated, and the kneaded material is in contact with the entire area of a narrow portion such as a large number of grooves and recesses, which makes it difficult to clean before and after operation in the manufacturing process. Therefore, it takes time, and the manufacturing process as a whole is low in work efficiency.

  On the other hand, in the above-described mold raising / lowering method, since the kneaded raw material touches only the contact portion of each mold, if only the mold is removable, only the mold can be removed and easily cleaned. As a result, not only is the work burden light, but the drive system can be a mechanism that simply raises and lowers the frame body that holds a plurality of molds in a line, so that the overall size of the apparatus can be avoided, and as a result It can be said that this method is more suitable for efficient spherical molding of kneaded raw material lump.

Japanese Patent No. 2849993 JP 2008-41 A

  In the conventional molding die raising / lowering spherical molding device as described above, the frame body holding the molding die is urged and pulled down by a spring against the belt conveyor, and the raw material block being conveyed Is received by the mold and rolled for a predetermined time, and then the cam projection is pushed down by the cam disk to partially push the end of the pressing plate, so that the frame body moves through the lifting arm continuous with the end. A configuration is adopted that rises against the pulling of the spring.

  However, in this elevating mechanism, the mold remains pressed against the upper surface of the belt conveyor until the cam acts on the pressing plate, and the relatively stopped mold is attached in the conveying direction by the belt conveyor. Since the material lump is rolled and molded only by the force, the mold is pushed down for a time required to obtain a sufficient number of revolutions to be molded into the desired spherical shape at a constant conveying speed. I will keep it. Therefore, it is necessary to provide a sufficient distance between the raw material blocks that are sequentially conveyed.

  However, in order to improve the production efficiency in mass production, the only way to improve the molding process efficiency is to increase the conveyance speed or shorten the pressing time of the mold and reduce the distance between the raw material ingots. However, there is a possibility that a load is applied to the transport drive system and the front and rear processing steps may be affected. In the latter case, the desired spherical shape cannot be formed, and the shape quality of the product may be deteriorated.

  In view of the above problems, the object of the present invention is to form a kneaded product raw material more efficiently than the conventional one without causing a burden on the transport drive system and a reduction in the shape quality of the product in a molding die raw material molding apparatus.

  According to a second aspect of the present invention, there is provided a kneaded product raw material forming apparatus according to the first aspect of the present invention, wherein the kneaded product raw material forming apparatus is lubricated to prevent the kneaded raw material from adhering to a region receiving the raw material lump of the mold.

It is.

And a holding part that holds a plurality of molds in a horizontal direction perpendicular to the conveying direction in the connected state, and a holding position of each mold with respect to the holding part can be adjusted in the horizontal direction. A mold adjusting mechanism for
A holding part adjusting mechanism is further provided to adjust the connecting position of the holding part with respect to the attachment part so as to be changeable back and forth along the transport direction.

It is characterized by being arranged in a plurality of rows.

  The method for forming a kneaded product raw material according to the invention described in claim 7 is a raw material lump in which the kneaded raw material of the kneaded product is distributed at predetermined intervals in a predetermined amount sequentially and placed on the belt conveyor and conveyed. On the other hand, when the raw material lump is received by a molding die when it is conveyed to a predetermined molding position, it is rolled into a spherical shape while being pushed back in the direction opposite to the conveyance direction.

The apparatus for molding a kneaded product raw material according to the present invention lowers the molding unit to a position where the molding die can catch the raw material lump of the kneaded product conveyed on the belt conveyor by the elevating mechanism and the reciprocating mechanism of the drive unit. after in conjunction with the lowered to forward the molding portion in the conveying direction and opposite direction, but to repeat the series of operations that is backward simultaneously retracted position when raising the molded part. This allows the raw material lump to be continuously received by the mold and rolled while being pushed back, so that it can be formed into a spherical shape. Compared with the above rolling, the number of rolling of the raw material lump per unit time at the same conveying speed is increased by the increase of the rolling biasing force due to the addition of the pushing back force by the mold. Therefore, if the number of times of rolling is the same, each molding time, that is, the lowering time of the molding die is shortened. Therefore, the distance between the raw material blocks placed and transported sequentially on the belt conveyor without lowering the transport speed is further increased. As a result, the processing efficiency of the raw material molding is remarkably improved, and there is an effect that mass production can be performed while maintaining the quality of the kneaded product.

It is a schematic perspective view which shows the shaping | molding state of the kneaded product raw material of the shaping | molding apparatus by one Example of this invention. It is a schematic side view of the shaping | molding apparatus of FIG. It is a schematic rear view of the shaping | molding apparatus of FIG. It is a partial schematic diagram which shows the schematic shape of the shaping | molding die with which the shaping | molding apparatus of FIG. 1 was mounted | worn, (a) is the top view seen from the upper direction at the time of shaping | molding, (b) is a side view.

  In the present invention, a kneaded raw material is distributed at predetermined intervals in a predetermined amount in sequence at predetermined intervals and formed into a spherical shape while receiving and rolling on the conveying path of a raw material lump placed on a belt conveyor. A molding unit having one or more molding dies, and the raw material lump is formed into a predetermined shape by driving the lifting mechanism and the reciprocating mechanism of the drive unit based on the signal information of the raw material lump detection from the detection unit. The molding part is lowered to a height position where the molding die receives the raw material lump when it reaches the position, and after the molding part is moved forward in the direction opposite to the conveyance direction, the molding part rises. At the same time, it is moved back to the retreat position where it does not interfere with the conveyance of the raw material lump, and a series of operations from the start of lowering of the molding unit to the return to the retraction position is repeated.

  In the molding apparatus of the present invention having such a configuration, when molding a raw material lump made of a paste material with high viscosity using fish paste or livestock paste into a spherical shape, the mold is lowered to the molding position. Accordingly, the forming die can be formed into a spherical shape by receiving the raw material lump conveyed on the belt conveyor and rolling it while pushing it back.

  Therefore, compared with the conventional rolling of the raw material lump only by the conveying urging force with respect to the mold that is stopped at the lowered position, the rolling urging force is increased by the addition of the pushing back force by the mold, and at the same conveying speed. Since the rolling frequency of the raw material lump per unit time is increased, if the same rolling frequency is set, each molding time, that is, the lowering maintenance time of the mold can be shortened. As a result, it is possible to set a smaller distance between the raw material blocks that are sequentially placed and conveyed on the belt conveyor without lowering the conveying speed, and such a short-time molding process can be performed to lower, forward, and raise the mold. -By repeating a series of operations of backward movement, it is possible to perform high-speed and reliable spherical molding with high efficiency with respect to the raw material lump that is sequentially conveyed.

  As described above, according to the molding apparatus of the present invention, the processing efficiency of raw material molding can be remarkably improved, and the product production efficiency can be increased while mass production can be easily realized while maintaining the quality of the kneaded product. Also, in order to make the molding shape of the raw material lump closer to a true sphere than in the past, the number of rolling can be increased without increasing the molding die lowering maintenance time in one molding process, so that the production efficiency is maintained. It is also possible to improve the shape quality of the product.

  In addition, a nozzle mechanism that injects a lubricating liquid such as water or edible oil to prevent the kneaded material from adhering to the area that receives the raw material lump of the mold is further provided, and the lubricating liquid is injected immediately before the mold is lowered. With this configuration, even when the raw material lump is received by the sprayed lubricating liquid during the molding process after the mold is lowered, the kneaded raw material is prevented from adhering to the area surface, and the raw material lump is transferred. Since the movement can be made smoother and deposits can be avoided, molding failure due to deposits and stoppage in the middle of continuous processing for removing deposits can be avoided. In this case, the control unit may control the nozzle mechanism so as to inject the lubricating liquid for a predetermined short time immediately before the lowering operation in conjunction with the operation with the driving unit.

  As the lifting mechanism and reciprocating mechanism of the drive unit in the present invention, it is simple to employ a cylinder mechanism. Specifically, the first cylinder mechanism that drives the connected molded parts to move up and down and the first cylinder can be mentioned as a simple and preferable configuration for moving the molded parts up and down and reciprocating using the cylinder mechanism. And a second cylinder mechanism that moves the mechanism forward and backward in the transport direction and in the transport direction. In this configuration, the mold can be moved forward and backward in the direction opposite to the transport direction along the transport direction along with the first cylinder mechanism by driving the second cylinder mechanism.

In addition, the drive unit performs a series of operations for rolling and forming by pressing back while receiving the raw material lump by lowering, moving forward, ascending, and retreating the forming unit at the required timing based on the signal information from the raw material lump detection unit In order to drive the lifting mechanism and the reciprocating mechanism while appropriately interlocking and synchronizing with each other, a control unit that controls the driving of the lifting mechanism and the reciprocating mechanism by receiving a signal from the detection unit and instructing the driving unit The configuration may be performed via

  For example, as the working fluid of the above-mentioned cylinder mechanism, an air operation system that has little influence on foods is particularly desirable. In such an air cylinder mechanism, the control unit is provided in the first and second cylinder mechanisms. On the other hand, the start and stop of the air supply and the flow path switching may be instructed in a timely manner based on the position information of the raw material block conveyed on the belt conveyor.

  Specifically, in the manufacturing process of the kneaded product, the work of sequentially placing the mixed and prepared kneaded raw material supplied from the tank in small amounts in parallel on a belt conveyor being driven via a quantitative distributor and the like is sequentially performed. It is carried out continuously at a predetermined interval, and the raw material lump is conveyed in a row at equal intervals, and after being subjected to spherical molding by a molding device for each row in the middle, it is further conveyed to the subsequent heating step. Therefore, in this process, when each raw material lump is subdivided and placed on the belt conveyor in this step, the control unit detects the raw material lump on a predetermined position by the sensor of the detection unit, and the molding device from the detected position Based on the distance to the molding position, the command is sent to the drive unit so that the molding die descends to the molding position in accordance with the molding position arrival time obtained in accordance with the conveying speed from the detection time point. The cylinder mechanism is controlled to be driven in conjunction with each other.

  In addition, the mold provided in the molding apparatus of the present invention may be in any form that can be made spherical by abutting and rolling on the raw material lump, and is not particularly limited. It is desirable to have a substantially U-shape as a form that easily rolls a mass of a highly viscous kneaded raw material mainly composed of a food material such as a spherical shape. In the case of such a substantially U-shaped mold, the raw material lump is received from the open side of the U-shape, is received by the inner surface of the bent portion on the back side, and is rolled along the inner surface of the bent portion while being pushed back. . Accordingly, in order to receive the target raw material lump more reliably, the substantially U-shaped molding die preferably has a gap width that widens from the bent portion toward the open side, and the rear side including the bent portion has a high height. It is preferable that the length dimension be equal to or larger than the maximum diameter of the desired shape.

  Furthermore, in this substantially U-shaped mold, at least the bent inner surface that receives the raw material lump is formed with an inclined inner surface that is continuously increased in thickness from the top toward the bottom. This can promote the rolling of the raw material lump. This is because an upward urging force acts so as to scoop up the raw material lump with which the inclined inner surface abuts, and the rotation rate of the raw material lump is improved.

  In addition, since the raw material lump is formed into a spherical shape corresponding to the curved surface of the bent portion of the substantially U-shaped mold, it is formed by appropriately selecting one having a curved surface and a height corresponding to the actual product diameter. It is desirable that the apparatus is detachably attached to the apparatus.

  Further, one or more raw material lumps are formed at a time at a predetermined forming position on the conveyance path by the forming apparatus, and one or more corresponding forming dies are provided in the forming portion. Therefore, when a plurality of raw material blocks are formed at a time, it is necessary to provide the same number of forming dies. For this reason, as a structure of a shaping | molding part, it is provided with the holding part connected with the attachment part of a 1st cylinder mechanism, and in this holding part, several horizontal direction orthogonal to the conveyance direction on a belt conveyor in the said connection state is provided. It is convenient that the molds are held in parallel.

  That is, when a plurality of raw material chunks are conveyed in parallel, the corresponding number of molding dies in the horizontal direction so that the number of raw material chunks in each row can be molded at a time. Are mounted on the holding portion in parallel, and the holding portion is connected to the mounting portion of the lifting mechanism, which is the first cylinder mechanism, by the lifting mechanism and the reciprocating mechanism of the driving portion, so that all the molds can be lifted and lowered integrally.・ Can be reciprocated. In addition, by forming the holding units in a plurality of rows and arranged at predetermined intervals along the conveying direction, it is possible to perform the forming process of two or more raw material lumps at a time in a single forming process. Further efficiency improvement can be achieved.

  Although the lowering position of the molding portion is uniquely determined by the installation positions of the first cylinder mechanism and the second cylinder mechanism, the holding portion adjustment that enables the connection position of the holding portion to the mounting portion of the first cylinder mechanism to be changed. By providing the mechanism, it is possible to adjust the raw material lump receiving position by the molding die in the transport direction. In addition, in the mounting portion of each molding die with respect to the holding portion, by providing a molding die adjusting mechanism that can be changed in the horizontal direction orthogonal to the conveying direction, each molding die is misaligned with respect to the raw material block to be received. It is possible to perform the forming process with higher accuracy without adjustment. As these adjusting mechanisms, for example, when the connection / mounting of the members is a screwing method of screw holes, it is simple and preferable that the screw hole of one member is a long hole extending in the adjusting direction.

  As one example of the present invention, a spherical molding apparatus for a kneaded product raw material provided with a molding part in which two rows of connecting bars as holding parts on which substantially U-shaped molding dies are mounted in parallel is arranged in FIGS. 4 shows the following. FIG. 1 is a schematic perspective view showing a molding state of the molding apparatus. FIG. 2 is a schematic side view of the molding apparatus, and FIG. 3 is a schematic rear view of the molding apparatus. FIG. 4 is a partial schematic diagram showing a schematic shape of a molding die attached to the molding apparatus, where (a) is a plan view seen from above during molding, and (b) is a side view.

  The forming apparatus 1 according to the present embodiment includes a belt conveyor 2 as a raw material lump 50 that is rounded to some extent while a kneaded raw material mixed and prepared supplied from a tank is subdivided by a fixed amount by a fixed amount distributor 3 such as a ball-type machine. It is installed in the middle of the path | route which is mounted on top and conveyed toward heat processing parts, such as an oil tank.

  The main molding apparatus 1 includes a second cylinder mechanism 20 composed of a pair of reciprocating cylinders installed on the bases 4 on both sides of the belt conveyor 2, and is fixed to the second cylinder mechanism 20, and a piston is formed in the vertical direction. The first cylinder mechanism 10 is composed of a pair of elevating cylinders for driving the rod 12.

Each reciprocating cylinder portion of the second cylinder mechanism 20 includes a casing (second casing) 21 in which a cylinder is provided, and a piston rod 22 penetrating the inside of the cylinder. By fixing the part, the second casing 21 moves forward and backward in the opposite direction to the transport direction along the piston rod 22. In this embodiment, since the movement of the housing to the backward side only returns the forward movement, the state in which the stroke on the forward side is secured is set as the initial state.

  On the other hand, each raising / lowering cylinder part of the 1st cylinder mechanism 10 is comprised from the 1st housing | casing 11 by which the cylinder was provided in the inside, and the piston rod 12 which slides the inside of this cylinder to an up-down direction, Piston rod of both sides is comprised. Both ends of the lifting / lowering operation plate 30 laid over the belt conveyor 2 are attached to the upper part of the belt conveyor 2. Accordingly, the lifting operation plate 30 is moved up and down by the synchronized vertical movement of the piston rod 12 in the pair of lifting cylinders.

  The lifting operation plate 30 is mounted with an inverted L-shaped mounting arm 32 via a mounting bracket 31 suspended from the back surface thereof, and corresponds to the number of juxtapositions of the raw material lump 50 conveyed on the belt conveyor 2. A connecting bar 33 as a holding portion, in which a number of substantially U-shaped forming dies 34 are fixed with screws at a predetermined interval, is connected to the lower end of the mounting arm 32 along a horizontal direction perpendicular to the conveying direction. Therefore, the molding die 34 is determined in advance on the conveying path of the raw material lump 50 by the belt conveyor 2 as the elevating operation plate 30 moves up and down by driving the piston rod 12 of the first cylinder mechanism 10 together with the connecting bar 33. While being lowered to the molding position, it is raised to a retreat position having a height that does not interfere with the conveyance of the raw material lump 50.

  Further, the first casings 11 of the first cylinder mechanisms 10 are fixed to the corresponding second casings 21, whereby the lifting operation plate 30 is driven by the second cylinder mechanism 20 together with the first cylinder portion. It is moved back and forth in the conveyance direction and in the opposite direction. In the present embodiment, the first and second cylinder mechanisms (10, 20) are driven by air supplied from a compressor.

  Therefore, the first and second cylinder mechanisms (10, 20) are driven and controlled by controlling the air supply from the control unit (not shown), so that the mounting bracket 31, the mounting arm 32, and the connection to the lifting operation plate 30 are connected. The plurality of molds 34 mounted via the bar 33 are lowered onto the belt conveyor 2 at an appropriate timing according to the conveying speed of the raw material lump 50 and moved in a direction opposite to the conveying direction by a predetermined distance. After being moved, it can be raised and moved back to the retracted position which is also the initial position in the same direction as the transport direction.

  The main molding apparatus 1 includes a detection unit (not shown) such as a sensor that detects the raw material lump 50 that is subdivided and placed on the belt conveyor 2, and the control unit starts from the detection position based on a detection signal from the detection unit. The first and second cylinder mechanisms (10, 20) are instructed to start a series of driving at a time interval from the detection time determined based on the distance to the molding position and the conveyance speed. That is, the first and second cylinder mechanisms (10, 20) lower the molding die 34 when reaching the molding position after a predetermined time from the detection of the raw material lump 50 in accordance with the control command from the control unit. Is moved forward by a predetermined distance in the direction opposite to the conveying direction, and the raw material block 50 is received and pushed back by the inner surface of the U-shaped bent portion of the molding die 34 to be formed into a spherical shape. Immediately the mold 34 can be raised and moved back to the retracted position.

  Furthermore, in this embodiment, the lubricating liquid injection mechanism 40 for injecting a lubricating liquid such as water or edible oil onto the inner surface of each mold 34 immediately before the mold 34 is lowered is provided. This injection mechanism 40 has an injection nozzle 42 mounted at a predetermined interval on a nozzle mounting base 41 supported at both ends so as to be bridged on the belt conveyor 2 on the upstream side of the installation site of the second cylinder mechanism 20. Is. Each injection nozzle 42 is inclined with respect to the corresponding mold 34 so that its injection axis intersects the inner surface of the bent portion of the mold 34 at the initial position (retracted position). A water / edible oil supply piping frame 43 is installed above the nozzle mounting base 41, and water and edible oil pumped from a supply source are supplied to each injection nozzle 42 via a supply pipe disposed in the frame. Supplied. Each injection nozzle 42 injects water and cooking oil with the air of an air compressor.

  The control unit further instructs the injection operation of the injection nozzle 42 when starting the lowering of the molding die 34 to spray water / edible oil on the inner surface of the molding unit for a short time. In this way, by spraying water or edible oil before the start of the molding process, the raw material lump 50 can be prevented from adhering to the mold 34 and rolling can be made smoother. In addition, as edible oil, vegetable oil which is liquid at normal temperature, for example, cottonseed oil, corn oil, soybean oil, rapeseed oil, etc. can be used.

  Raw materials that are transported in order and at predetermined intervals by repeating the above-mentioned series of actions including lowering, forward movement, ascending, and backward movement including water / edible oil injection at the timing according to the conveying speed of the raw material lump. Spherical molding can be continuously performed in a short time corresponding to the lump row and sent to the previous heating step.

  In the molding apparatus 1 according to the present embodiment, the raw material block 50 is pushed back by advancing the molding die 34 in the direction opposite to the conveying direction during spherical molding, so that the conventional molding die 34 remains stopped at the lowered position. Compared with the rolling of the raw material lump only by the conveying energizing force of the belt conveyor, the number of rolling of the raw material lump per unit time at the same conveying speed is increased by the increase of the rolling energizing force due to the pushing back force applied by the molding die 34. Increase. Accordingly, if the number of rollings is the same, each molding time, that is, the descent maintenance time of the molding die 34 is shortened. Therefore, the interval distance between the raw material blocks that are sequentially placed and conveyed on the belt conveyor without reducing the conveying speed is set. It can be set smaller, and the processing efficiency of raw material molding can be greatly improved.

  In addition, as shown in FIG. 4, the molding die 34 attached to the molding apparatus 1 in this embodiment is spaced from the U-shaped bent portion toward the open side in order to receive the target raw material mass 50 more reliably. The width is widened, and the height dimension of the mold 34 is equal to or larger than the spherical maximum diameter of the raw material lump 50. Further, the bent portion region of the mold 34 continuously increases in thickness inward from the upper portion toward the lower portion, and the inner surface of the bent portion where the raw material lump 50 is received is inclined upward. Since the upward urging force that scoops up by contacting the inclined inner surface 35 is applied to the raw material lump 50, the rolling inside the mold 34 is promoted, which contributes to the aid of spherical molding. .

  In this embodiment, each mold 34 is fixed to the connecting bar 33 with screws, and as a mold adjusting mechanism, the screw hole on the side of the connecting bar 33 is made into a long hole 33H and the mounting position of the mold 34 is fixed. Can be changed in the horizontal direction perpendicular to the conveying direction. Thereby, it can adjust so that the raw material lump receiving position of each shaping | molding die 34 may cancel | displace with respect to an actual raw material lump conveyance position. Further, the connecting bar 33 is also fixed to the mounting arm 32 with a screw, and as a holding portion adjusting mechanism, the screw hole on the mounting arm 32 side is made into a long hole 32H, so that the connecting position of the connecting bar 33 is set in the transport direction. The lowering position on the belt conveyor of the mold 34 attached to the same connecting bar 33 can be adjusted integrally.

  In the molding apparatus according to the present embodiment having the above-described configuration, a raw material lump of 13.0 g per piece made of a kneaded raw material having a viscosity of 5000 to 13000 cP (centipoise) has a speed of 12.8 m / min. The forming process was carried out with the setting of moving back almost 30 mm almost instantaneously as the push-back distance of the forming die 34 that provides a sufficient number of rolling operations for spherical forming. In this case, the distance between the raw material ingots in the conveying direction can be set to 130 mm, and 96 raw material ingots can be formed into a spherical shape for one mold 34 per minute. This was about twice as many treatments as in the conventional spherical molding without pushing back with the same number of rollings under the same conveying conditions. In addition, when the shaping | molding die 34 is provided with the inclined surface which thickness increased toward the lower part from the upper part of the bending part area | region, it is constant thickness from the upper part to the lower part without such an inclined surface in a bending part area | region. Compared with the mold which is, the rotation rate of the raw material lump was improved about 1.3 to 1.5 times.

  In addition, in the shaping | molding apparatus 1 of a present Example, it was set as the structure which attaches the connection bar 33 equipped with the shaping | molding die 34 to two places of the attachment arm 32, and the intermediate position lower part of a front-end | tip lower part and the L-shaped standup. As a result, the two connecting bars 33 each having the molding die 34 attached thereto are attached in parallel to each other, so that the double molding die 34 can be made to repeat the above-described series of lowering / forward / upward / reverse driving. Therefore, the molding process can be performed on the raw material lump 50 for two rows at a time, and the processing efficiency can be further improved. In this case, the injection nozzles 42 of the injection mechanism 40 may be arranged in two rows corresponding to the molding die 34.

  As described above, by using the molding apparatus according to the present embodiment, particularly for a highly viscous kneaded raw material made of fish paste or livestock paste, for example, having a viscosity of 5000 to 13000 cP (centipoise). Thus, since the spherical molding process can be performed more efficiently than in the past, as a result, mass production of spherical products can be easily realized without increasing or incurring the conveyance speed that imposes a burden on the drive system.

  Further, in the molding apparatus 1, each molding die 34 can be attached to and detached from the connecting bar 33. Thereby, after completion of the predetermined work process, only the mold 34 can be removed and cleaned. Since only the mold 34 is in direct contact with the raw material in the molding apparatus, there is no need for the troublesome work of cleaning various complicated shaped members.

  Conventionally, the sphere celestial machine used as a quantitative distributor in the manufacturing process of fish paste products is provided with a rotating blade at the lower end of the pipe to which the kneaded raw material is supplied, and is continuous from the lower end opening of the pipe. The blades are sequentially arranged on a belt conveyor which is moving as a small lump separated by a fixed amount every rotation with respect to the kneaded raw material extruded. A sensor is attached to the blade of this sphere celestial device, and the blade rotates once to place the raw material lump on the belt conveyor, and a signal is sent to the control unit. Therefore, also in the present embodiment, when the spherical weather provided with such a blade is used as a quantitative distributor, in order to command the drive of the first and second cylinder mechanisms (10, 20) in the control unit. It is convenient to use a signal from the blade sensor as a raw material lump detection signal.

  Further, it is desirable to cover the main part of the molding apparatus including the molding region and the water / food oil injection region during the molding process. In this case, installation and removal or a simple frame cover may be provided.
