Title: Spring roll making apparatus

Description:
TECHNICAL FIELD 
     The present invention relates to a spring roll making apparatus, and more particularly, to a spring roll making apparatus which allows a large quantity of spring rolls to be rapidly produced through an automated process. 
     BACKGROUND ART 
     Generally, spring rolls are food which is made of wheat flour or rice flour, like a pancake, and stuffed with filling and fried. Such a spring roll is called “Chūn Juăn” in China, “Cha Zio” in Vietnam, and “Harumaki” in Japan. 
     The “Chūn Juăn” is a type of dumpling. Wheat flour, starch powder, eggs, and the like are mixed to look like a pancake, and then the pancake is stuffed with filling that is made by mixing vegetables such as shiitake mushrooms, bean sprouts, and bamboo shoots, minced pork, shrimp, or the like, rolled up, and fried in oil. 
     The “Cha Zio” is a food made by putting minced pork, shrimp meat, and vegetables such as carrots, green peppers, mushrooms, and the like on a Vietnamese spring roll called a rice paper, rolled up, and being fried in oil. To make the “Cha Zio,” the Vietnamese spring roll is placed as a rhombus shape, filling is placed a little below the center of the spring roll, a front part of the spring roll is folded first and both wing parts are folded inward, and the Vietnamese spring roll is rolled and fried in oil. 
     However, conventionally, since it is difficult to automate a process of making spring rolls such as “Cha Zio” so that the spring rolls are manually produced, there is a problem in that the production amount cannot be increased. Therefore, there is a need to solve the above problem. 
     The background technology of the present invention is disclosed in Korean Unexamined Patent Application Publication No. 2004-0028544 (Published on Apr. 3, 2004, Title: SPRING ROLL AND METHOD OF MANUFACTURING THE SAME).

In addition, the softening spray part  31  may be disposed above the second supply part  12  to spray hot water onto the rice paper  100 . 
       FIG. 4  is a schematic view illustrating a softening steam part in the spring roll making apparatus according to the embodiment of the present invention. Referring to  FIG. 4 , the softening part  30  according to the embodiment of the present invention may further include a softening steam part  32  which supplies steam onto the rice paper  100 . That is, moisture may first be supplied to an upper surface of the rice paper  100  by the softening spray part  31 , and the moisture may be supplied to an entire surface of the rice paper  100  through the steam so that the rice paper  100  may be rapidly softened. 
     The softening steam part  32  according to the embodiment of the present invention includes steam stands  321 , a steam tank part  322 , and a steam heating part  323 . The softening steam part  32  may cover a part of the moving part  20  to supply the steam to the rice paper  100  that is moved to the moving part  20 . 
     The plurality of steam stands  321  support the steam tank part  322  in which water is stored. For example, four steam stands  321  may be fixed to the ground and may be moved to a destination by rolling separate wheels thereof. 
     The steam tank part  322  covers the moving part  20 . For example, a belt conveyor of the moving part  20  may pass through an inside of the steam tank part  322 , and water may be stored under the belt of the moving part  20 . 
     The steam heating part  323  is mounted on the steam tank part  322  and heats the stored water. For example, the steam heating part  323  may be a coil that heats water when power is applied.

For example, left and right sides of the rice paper  100  are alternately folded by the third folding part  53  so that the part folded later may protrude to have a length greater than a length of the filling  200 , and the protruding part may be corrected by the fourth folding part  54 . 
       FIG. 6  is a schematic view illustrating the first folding part in the spring roll making apparatus according to the embodiment of the present invention. Referring to  FIG. 6 , the first folding part  51  according to the embodiment of the present invention includes a first spray part  511  and a first engaging part  512 . 
     The first spray part  511  sprays air onto the front end part of the rice paper  100  and allows the rice paper  100  to be wrapped around the filling  200 . For example, the first spray part  511  may be mounted on the moving part  20  and disposed below the belt part  21  that is moved in a caterpillar manner. When the first spray part  511  sprays air, the front end part of the rice paper  100  may be flipped by belt holes  211  formed in the belt part  21 . Accordingly, the front end part of the rice paper  100  may be wrapped around the filling  200 . 
     The first engaging part  512  allows the rice paper  100  that is moved by the moving part  20  to be caught and rotated several times. For example, the first engaging part  512  may include a first engaging support part  5121 , which is fixedly provided on the moving part  20 , and a first engaging contact part  5122  which is rotatably mounted on the first engaging support part  5121  and which is brought into contact with the rice paper  100  that is moved by being wrapped around the filling  200 . Accordingly, even when the rice paper  100  is wrapped around only an upper end part of the filling  200  by the first spray part  511 , the filling  200  may be rotated by the first engaging part  512  so that the rice paper  100  may be stably wrapped around the filling  200 . In this case, a plurality of first engaging contact protrusions  5123  may be formed in a longitudinal direction of the first engaging contact part  5122  to induce smooth contact and friction with the rice paper  100  wrapped around the filling  200 . Meanwhile, the first engaging support part  5121  may be mounted on a movement fixing part  22  fixedly provided on the moving part  20  and disposed above the belt part  2 .

     The second support part  521  is fixedly provided on the movement fixing part  22  and disposed above the belt part  21 . The second rod  522  is rotatably mounted on the second support part  521 . The second rotating plates  523  are provided in a pair to be mounted rotatably on an end part of the second rod  522  and presses the rice paper  100  placed on the both sides of the filling  200 . 
     For example, each of the second rotating plates  523  may be rotatably mounted on one of two sides of the second rod  522 . In this case, a distance between the second rotating plates  523  may be greater than the length of the filling  200 . Accordingly, the second rotating plates  523  may form boundary lines for folding by pressing the rice paper  100  located at the both side end parts of the filling  200 . 
     Meanwhile, a second variable part  524  mounted on the movement fixing part  22  may be coupled to the second rod  522 , and a length thereof may be varied to rotate the second rod  522 . That is, when the sensor part  70  detects the rice paper  100 , the length of the second variable part  524  may be increased and thus the second rotating plates  523  disposed above the belt part  21  may be brought into contact with the belt part  21 .

     Meanwhile, a left variable part  5624  mounted on the movement fixing part  22  may be coupled to the left rod  5621 , and a length thereof may be varied to rotate the left rod  5621 . That is, when the sensor part  70  detects the rice paper  100 , the length of the left variable part  5624  may be increased and thus the left rotating part  5622  disposed above the belt part  21  may be brought into contact with the belt part  21 . 
     The right pressing part  563  is rotatably mounted on the left-and-right support part  561  and presses the right end part of the rice paper  100 . For example, the right pressing part  563  may include a right rod  5631  which is rotatably provided on the left-and-right support part  561 , a right rotating part  5632  which is rotatably mounted on a lower end part of the right rod  5631  and is brought into contact with the belt part  21 , and a right contact part  5633  which extends in the traveling direction of the rice paper  100  from the lower end part of the right rod  5631  and is brought into contact with the rice paper  100 . 
     Meanwhile, a right variable part  5634  mounted on the movement fixing part  22  may be coupled to the right rod  5631 , and a length thereof may be varied to rotate the right rod  5631 . That is, when the sensor part  70  detects the rice paper  100 , the length of the right variable part  5634  may be increased and thus the right rotating part  5632  disposed above the belt part  21  may be brought into contact with the belt part  21 . 
       FIG. 10  is a schematic view illustrating the fourth folding part in the spring roll making apparatus according to the embodiment of the present invention. Referring to  FIG. 10 , the fourth folding part  54  according to the embodiment of the present invention includes a fourth pressing part  541  and a fourth spray part  542 . 
     The fourth pressing part  541  presses the end part of the rice paper  100 . The fourth pressing part  541  may press the rear end part of the rice paper  100  moved by the moving part  20  to restrict the movement of the rice paper  100 . 
     The fourth pressing part  541  according to the embodiment of the present invention may include a fourth pressing support part  5411 , fourth pressing rods  5412 , and a fourth pressing contact part  5413 .

     Meanwhile, a fourth pressing variable part  5414  mounted on the movement fixing part  22  may be coupled to the fourth pressing rod  5412 , and a length thereof may be varied to rotate the fourth pressing rod  5412 . That is, when the sensor part  70  detects the rice paper  100 , the length of the fourth pressing variable part  5414  may be increased and thus the fourth pressing contact part  5413  disposed above the belt part  21  may be brought into contact with the belt part  21 . 
     The fourth spray part  542  sprays air onto the rice paper  100  to fold the side end part of the rice paper  100 . For example, in a state in which the fourth pressing part  541  presses the rear end part of the rice paper  100 , the fourth spray part  542  sprays air onto the rice paper  100  and thus the rice paper  100  may be prevented from protruding greater than the length of the filling  200 .

     The rotation guide part  62  is mounted on the rotation support part  61 , has a length extending in the traveling direction of the rice paper  100 , and allows the moving rice paper  100  to be caught and rolled. For example, the rotation guide part  62  may have one end part mounted on the rotation support part  61  and the other end part in contact with the belt part  21 . In addition, the rice paper  100  in contact with the rotation guide part  62  may be rotated while being moved in the traveling direction of the belt part  21  due to a moving force by the belt part  21 . 
       FIG. 12  is a schematic flowchart illustrating a spring roll making method according to an embodiment of the present invention. The spring roll making method will be described with reference to  FIG. 12  as follows. 
     A supply part  10  supplies rice papers  100  (S 10 ), and a moving part  20  moves the rice papers  100  (S 20 ). That is, the supply part  10  automatically supplies the dried rice papers  100 , and the supplied rice papers  100  having a tetragonal shape is moved by the moving part  20 . In this case, the rice paper  100  may be moved as a rhombus shape so that corners may be formed at front and rear end parts of the rice paper  100 . 
     The rice paper  100  moved by the supply part  10  and the moving part  20  is softened by a softening part  30  (S 30 ). When the softening of the rice paper  100  is completed, a feeding part  40  feeds a filling  200  onto the rice paper  100  (S 40 ). 
     The rice paper  100  on which the filling  200  is placed is continuously moved by the moving part  20  and is folded by a folding part  50  (S 50 ). The rice paper  100  folded by the folding part  50  is wrapped around the filling  200  while being rotated by a rotating part  60  (S 60 ). 
     That is, the rice paper  100  may be wrapped around the filling  200  so as to correspond to a length of the filling  200  while passing through the folding part  50  and the rotating part  60  in sequence by the moving part  20 .

To describe an operation of the folding part  50  with reference to  FIG. 14 , a first folding part  51 , a second folding part  52 , a third folding part  53 , and a fourth folding part  54  are sequentially disposed in a traveling direction of the rice paper  100  moved by the moving part  20  to fold the rice paper  100 . 
     That is, the first folding part  51  allows a front end part of the rice paper  100  to be wrapped around the filling  200  (S 51 ), and the second folding part  52  presses the rice paper  100  placed on both sides of the filling  200  (S 52 ). 
     The third folding part  53  folds the rice paper  100  placed on the both sides of the filling  200  (S 53 ), and the fourth folding part  54  folds a protruding part of the rice paper  100  (S 54 ). 
       FIG. 15  is a schematic flowchart illustrating a process of operating the third folding part in the spring roll making method according to the embodiment of the present invention. To describe an operation of the third folding part  53  with reference to  FIG. 15 , a third central pressing part  55  presses the filling  200  wrapped in the moving rice paper  100  to restrict movement of the filling  200  (S 531 ). 
     While the third central pressing part  55  continuously presses the moving filling  200 , a third left-and-right pressing part  56  presses a left wing of the rice paper  100  (S 532 ), and a third left spray part  57  sprays air onto a left end part of the rice paper  100  so that a left end part of the rice paper  100  overlaps above the filling  200  (S 533 ). 
     When the operation of the third left spray part  57  is completed, the third left-and-right pressing part  56  presses a right wing of the rice paper  100  (S 534 ), and the third right spray part  58  sprays air onto a right end part of the rice paper  100  so that a right end part of the rice paper  100  overlaps above the filling  200  (S 535 ). 
     Meanwhile,  FIG. 16  is a schematic view illustrating another example of the first folding part. Referring to  FIG. 16 , a first engaging part  512  may include a first engaging rod  5125  and a first engaging guide part  5126 . The first engaging rod  5125  may be fixedly provided on the moving part  20 , and the first engaging guide part  5126  may be rotatably mounted on the first engaging rod  5125 . A lower end part of the first engaging guide part  5126  may be brought into contact with the rice paper  100  wrapped around the filling  200 , and an upper end part of the first engaging guide part  5126  may be disposed above the first engaging rod  5125 . The first engaging guide part  5126  may be rotated when being brought into contact with the rice paper  100  and may return to an original position thereof when an external force is removed. In this case, when a separate tension spring is applied, the first engaging guide part  5126  may rapidly return to the original position thereof.

The second motor driver  525  may be mounted on the movement fixing part  22  and disposed above the belt part  21 . When power is applied, the second motor driver  525  may be driven to rotate a motor shaft. The second motor rotating part  526  may be coupled to the motor shaft of the second motor driver  525  and may be rotated when the second motor driver  525  is driven. The second motor rotating part  526  may include a second motor rotation shaft  5261 , which is coupled to the motor shaft of the second motor driver  525 , and second motor rotation contact parts  5262  which are formed on the second motor rotation shaft  5261  and provided in a pair to face each other. The second motor rotation contact parts  5262  may be rotated while being in contact with the belt part  21 , and a distance between the second motor rotation contact parts  5262  may be greater than the length of the filling  200  so that the second motor rotation contact parts  5262  may press the rice paper  100 , and thus boundary lines for folding may be formed. 
       FIG. 18  is a schematic view illustrating another example of the third folding part. Referring to  FIG. 18 , a third left-and-right pressing part  56  may include a third left-and-right operation part  565 , a third left-and-right rod  566 , and third left-and-right pressing parts  567 . The third left-and-right operation part  565  may be mounted on the movement fixing part  22 , and a length of a piston may be changed according to hydraulic pressure or pneumatic pressure so that a height of the third left-and-right rod  566  may be adjusted. A pair of the third left-and-right pressing parts  567  may be mounted on the third left-and-right rod  566 . When the sensor part  70  detects the rice paper  100  in the above state, a length of the third left-and-right operation part  565  may be increased, the third left-and-right pressing part  567  may be moved downward to press each of left-and-right wing parts of the rice paper  100  moved on the belt part  21 , and a third left spray part  57  and a third right spray part  58  sequentially spray air so that the left and right wings of the rice paper  100  may be folded. 
       FIG. 19  is a schematic view illustrating the feeding part in the spring roll making apparatus according to the embodiment of the present invention. Referring to  FIG. 19 , the feeding part  40  includes a feed supply part  41  and a feed cutting part  42  and cuts to subdivide the filling  200 . In addition, the feeding part  40  may further include a feed belt part  43 , a feed stopper  44 , and a feed dropping part  45  and may allow the subdivided fillings  200  to be sequentially dropped onto the moving rice paper  100 . 
     The feed supply part  41  may supply the filling  200 , the feed cutting part  42  may cut the filling  200  provided from the feed supply part  41 , the feed belt part  43  may guide the cut and subdivided fillings  200 , the feed stopper  44  may temporarily stop movement of the filling  200  being moved by the feed belt part  43 , and the feed dropping part  45  may drop the filling  200  of which the movement is stopped by the feed stopper  44  from the feed belt part  43 . 
       FIG. 20  is a schematic view illustrating the feed supply part in the spring roll making apparatus according to the embodiment of the present invention. Referring to  FIG. 20 , the feed supply part  41  according to the embodiment of the present invention includes a supply inlet part  411 , a supply guide part  412 , and a supply operation part  413 . 
     The supply guide part  412  guides the filling  200  introduced into the supply inlet part  411 , and the supply operation part  413  allows the filling  200  introduced into the supply guide part  412  to be provided to an end part of the supply guide part  412 . 
     For example, the supply inlet part  411  may have a hopper shape that communicates with one end part of the supply guide part  412 , and an operator feeds the filling  200  into the supply inlet part  411 . In addition, the supply guide part  412  may have a cylindrical shape, and the supply operation part  413  may be inserted into the supply guide part  412  to move the filling  200 . In this case, the supply operation part  413  may move the filling  200  in one direction while a rod having a spiral shape is rotated or may move the filling  200  through a change in the length of the piston. 
     A guide hole  419  formed in the end part of the supply guide part  412  has an angular shape so that the filling  200  is provided in the angular shape. That is, in order to suppress the rotation of the filling  200  dropped on the rice paper  100 , the filling  200  may pass through the guide hole  419  having the angular shape. In this case, the guide hole  419  may have a triangular or tetragonal hole shape. 
       FIG. 21  is a schematic view illustrating the feed cutting part in the spring roll making apparatus according to the embodiment of the present invention. Referring to  FIG. 21 , the feed cutting part  42  according to the embodiment of the present invention includes a cutting driver  421 , a cutting link part  422 , a cutting blade part  423 , and a cutting rotation part  424 . 
     A vertical length of the cutting driver  421  may be varied. For example, the cutting driver  421  may be fixedly provided on the supply guide part  412  or a separate fixture, and a length of the cutting driver  421  may be adjusted by moving a piston up and down according to hydraulic pressure or pneumatic pressure. 
     The cutting link part  422  is rotatably mounted on the cutting driver  421  and has a height adjusted according to the length of the cutting driver  421 . For example, the cutting link part  422  may include a link horizontal part  4221  having a horizontal length and rotatably mounted on the cutting driver  421  to adjust a height thereof, and a link vertical part  4222  extending downward from one end part of the link horizontal part  4221 . 
     The cutting blade part  423  is formed on the cutting link part  422  and cuts the filling  200 . For example, the cutting blade part  423  may have a plate shape that covers the guide hole  419  and may be mounted on the link vertical part  4222 . 
     The cutting rotation part  424  is connected to the cutting link part  422 , and a length thereof is varied to rotate the cutting link part  422 . For example, the cutting rotation part  424  may be mounted on the supply guide part  412  or a separate fixture, and the length of the cutting rotation part  424  may be adjusted by moving the piston up and down according to hydraulic pressure or pneumatic pressure. The cutting rotation part  424  may be connected to the other end part of the link horizontal part  4221 . 
       FIG. 22  is a schematic view illustrating a process of cutting the filling in the spring roll making apparatus according to the embodiment of the present invention. A schematic description of the process of cutting the filling  200  will be described with reference to  FIG. 22  as follows. 
     When the filling  200  is provided from the feed supply part  41 , the length of the cutting driver  421  is increased so that the cutting link part  422  is moved downward. When the cutting link part  422  is moved downward, the cutting blade part  423  cuts the filling  200  provided continuously. In this case, the length of the cutting rotation part  424  is increased to be the same as the length of the cutting driver  421  so that the cutting link part  422  may be moved linearly downward. 
     Meanwhile, when the cutting blade part  423  cuts the filling  200 , the length of the cutting rotation part  424  is reduced. As a result, while the other end part of the cutting link part  422  is lifted upward, one end part of the cutting link part  422  is rotated. In addition, the cutting blade part  423  mounted on the cutting link part  422  may be moved to take the cut filling  200  out and thus may additionally cut or separate tendons and the like included in the filling  200 . 
       FIG. 23  is a schematic view illustrating the feed stopper in the spring roll making apparatus according to the embodiment of the present invention. Referring to  FIG. 23 , the feed stopper  44  according to the embodiment of the present invention includes a stopper head  441  and a stopper variable part  442 . 
     The stopper head  441  is brought into contact with the filling  200 . For example, the feed belt part  43  that allows the filling  200  to be moved in a belt conveyor method may guide the filling  200  that is cut and dropped by the feed cutting part  42 , and the stopper head  441  may be disposed above the feed belt part  43 . In this case, the feed belt part  43  may cross the moving part  20 , and the movement of the filling  200  may be restricted by the stopper head  441  disposed in the movement path of the filling  200 . The stopper head  441  may be covered with a replaceable sanitary cover. 
     The stopper variable part  442  is connected to the stopper head  441 , and a length is varied to move the stopper head  441 . For example, the stopper variable part  442  may have a length in a longitudinal direction of the feed belt part  43 , and the length of the stopper variable part  442  may be adjusted by pneumatic pressure or hydraulic pressure to move the stopper head  441 . 
     When the feed dropping part  45  pushes the filling  200  stopped by the stopper head  441 , the stopper variable part  442  moves the stopper head  441  so that the stopper head  441  is spaced apart from the filling  200 . 
     That is, when the feed dropping part  45  is operated while the filling  200  is attached to the stopper head  441 , the filling  200  may not be smoothly separated from the stopper head  441  due to the moisture contained in the filling so that the filling  200  may not be dropped in a set state. 
     Therefore, when the feed dropping part  45  pushes the filling  200 , the stopper head  441  may be spaced apart from the filling  200 , and thus the filling  200  may be dropped in the set state and be placed on the rice paper  100  moved by the moving part  20 . 
       FIG. 24  is a schematic view illustrating the feed dropping part in the spring roll making apparatus according to the embodiment of the present invention. Referring to  FIG. 24 , the feed dropping part  45  according to the embodiment of the present invention includes a drop rod  451 , a drop operation part  452 , and a drop plate  453 . 
     The drop rod  451  is disposed above the feed stopper  44 . For example, the drop rod  451  may have a length in a longitudinal direction of the feed belt part  43 , and the drop operation part  452  may be mounted on the drop rod  451 . 
     The drop operation part  452  is mounted on the drop rod  451 , and the drop plate  453  connected to the drop operation part  452  pushes the filling  200  placed on the feed belt part  43  while being rotated by the drop operation part  452 . As a result, the filling  200  dropped from the feed belt part  43  may be placed on the moving part  20 . 
     For example, the drop operation part  452  may be a motor mounted on the drop rod  451 , and the drop plate  453  connected to a rotation shaft of the drop operation part  452  may be rotated by the drop operation part  452  to push the filling  200 . In addition, the drop operation part  452  may be a cylinder having a variable length and mounted on the drop rod  451 , and the drop plate  453  connected to the drop operation part  452  may be rotatably coupled to the drop rod  451  and may rotate according to a change in length of the drop operation part  452  to push the filling  200 . Meanwhile, various driving bodies that rotate the drop plate  453  in one direction and return to an original state may be applied as the drop operation part  452 . 
       FIG. 25  is a schematic view illustrating a process of dropping the filling in the spring roll making apparatus according to the embodiment of the present invention. The process of dropping the filling  200  will be schematically described with reference to  FIG. 25  as follows. 
     When the subdivided filling  200  reaches the feed belt part  43 , the filling  200  is moved in the longitudinal direction of the feed belt part  43 . The filling  200  that is moved in the longitudinal direction of the feed belt part  43  is brought into contact with the stopper head  441  so that the movement of the filling  200  is restricted. 
     When the filling  200  reaches the stopper head  441 , the drop operation part  452  is driven so that the drop plate  453  is rotated. When the drop plate  453  is rotated, the filling  200  placed on the feed belt part  43  is pushed out to be dropped to the moving part  20  disposed below the feed belt part  43 . 
     In this case, the stopper variable part  442  is driven so that the stopper head  441  is spaced apart from the filling  200 , and thus interference between the drop plate  453  and the stopper head  441  may be prevented and deformation of the filling  200  due to a coupling force between the filling  200  and the stopper head  441  may be blocked. The stopper variable part  442  may be driven simultaneously with the drop operation part  452 . 
     While the present invention has been described with reference to the embodiment illustrated in the accompanying drawings, the embodiment should be considered in a descriptive sense only, and it should be understood by those skilled in the art that various alterations and equivalent other embodiments may be made. 
     Therefore, the scope of the present invention should be defined by only the following claims.
