Description

  The present invention relates to a semi-automatic pizza sauce coating machine and a pizza pie manufacturing system incorporating this machine, in which a pizza sauce dropped on the top surface of a pizza crust conveyed by a belt conveyor is applied to the top surface of a circular pizza crust.

  When pizza pie is continuously manufactured by the flow operation of a belt conveyor, it is difficult to apply a viscous pizza sauce on the top surface of the pizza crust, and the surface of the pizza crust may be uneven. For example, use a spoon or a spatula. I went by work. Therefore, it takes 6 to 10 seconds to apply one sheet, and a method for improving this speed has been demanded. To solve this, there is a method to stretch the pizza sauce by pressing the rotating body against the pizza crust.

However, when holding the rotating body including the motor and pressing it on the top of the pizza crust, if the force is strong, the pizza sauce gathers around the pizza crust, and if the force is weak, the difficulty that the pizza sauce does not spread around the pizza crust is there. It is also difficult to support the weight of the rotating body including the motor and follow the movement of the pizza crust moving at a predetermined speed on the belt conveyor.
There is an example in which a belt conveyor is run at a constant speed and pizza sauce is jetted all at once from long nozzles provided across the belt conveyor. In this example, since the pizza sauce is dripped at a place other than the pizza crust, the pizza sauce receiver is provided at the lower part of the belt conveyor and returned.

  The present invention was created to solve the above-mentioned problems, and the object of the present invention is to quickly stretch and apply a pizza sauce dropped on the upper surface of a pizza crust flowing on a belt conveyor with a simple mechanism. An object is to provide a semi-automatic pizza sauce coater and a pizza pie manufacturing system incorporating this machine.

  A pizza sauce coating machine according to the present invention includes a rotation drive source driven by a switch operation, an application plate connected to the rotation shaft of the rotation drive source and revolving around the rotation shaft, and applying the pizza sauce on the upper surface of the pizza crust by the revolution, A ring-shaped frame that abuts the upper surface of the pizza crust when applying the pizza sauce and surrounds the revolution region of the application plate; and a biasing means that urges the rotation drive source, the application plate, and the entire frame in a direction away from the pizza crust; It has a left and right handle for moving the rotation drive source, the coating plate, and the entire frame in the contact / separation direction with the pizza crust and the conveyance direction of the pizza crust.

  It is preferable that a plurality of groove portions provided to be orthogonal to each other are formed on the pizza crust facing surface of the coating plate.

  It is preferable that the said application | coating board is attached to the connection link attached to the said rotating shaft so that rotation is possible.

  The coating plate is preferably inclined with respect to the center of the top surface of the pizza crust.

  A pizza pie manufacturing system according to the present invention includes a pizza crust forming unit for forming a pizza crust from pizza dough, a pizza crust drawing unit, a heating unit for baking the pizza crust, a pizza sauce supply unit for supplying pizza sauce to the upper surface of the pizza crust, and 4. A pizza sauce coating unit in which the pizza sauce coating machine according to any one of 4 is disposed, a topping unit that performs topping on the pizza crust, and a packaging unit that wraps the topped pizza crust on a conveyance path that is moved by a belt conveyor at a predetermined speed. It is arranged.

  Since the pizza sauce coating machine according to the present invention is installed by suspending by a biasing means, that is, a spring, from a support member provided above the belt conveyor, when the apparatus is pressed against the upper surface of the pizza crust by the force of a human arm, The spring can be selected so as to have a strong pressing force. Then, when the arm is pulled out, the device can be immediately separated from the pizza crust. In addition, since there are left and right handles, the pizza crust can be easily moved in the transport direction. That is, the apparatus can follow the movement of the pizza crust. A coating plate with half the pizza crust diameter is attached to the rotating shaft of the motor, which is the rotation drive source, and the coating plate rotates slowly so that it revolves around the top surface of the pizza crust, so the pizza sauce is immediately stretched and painted on the top surface of the pizza crust. be able to. Since the ring-shaped frame is smaller than the diameter of the pizza crust and surrounds the moving area of the coating plate, the pizza sauce can be prevented from protruding outside the pizza crust.

  In addition, a plurality of grooves perpendicular to each other are formed in a circular area surrounded by a diameter about half the diameter of the coating plate at the center of the bottom surface of the coating plate, so that the bottom of the coating plate is flat and the pizza sauce Compared with surface contact with the pizza sauce, the pizza sauce can be stretched reliably and applied evenly.

  Furthermore, since the coating plate is rotatably attached to a connecting link attached to the motor rotation shaft, it can be rotated counterclockwise by contact resistance with the pizza crust if the revolution is clockwise. Therefore, the pizza sauce can be uniformly applied by both the rotation and revolution.

  In addition to this, since the coating plate is attached in an inclined state with respect to the center portion of the pizza crust, if the revolution is clockwise by the contact resistance between the peripheral portion of the pizza crust and the coating plate, the coating plate rotates counterclockwise. be able to. The pizza sauce piled up near the center of the pizza crust is caught by a gap provided on the outer peripheral portion of the bottom surface of the coating plate by revolution, and is stretched to the peripheral portion of the top surface of the pizza crust by rotation. Since the coating plate is attached at an inclination, the thickness of the pizza sauce along the circumferential direction is uniform, and the central portion of the pizza crust is thick. According to this coating method, when the pizza pie is divided into sectors, there is no bias in the amount of pizza sauce in each piece.

  The pizza pie manufacturing system according to the fifth aspect of the present invention is a medium-scale pizza pie manufacturing system constructed by incorporating the pizza sauce coating machine into a production line conveyed by a belt conveyor. The time it takes to apply the pizza sauce can be improved by about twice or more compared to the case where all work is done manually. For example, when the speed of the belt conveyor is operated at about 15 sheets / minute, which is about 1 sheet per 4 seconds with an allowance for work, the performance after baking of pizza pie is about 900 sheets / minute without the pizza sauce coating becoming a neck. It can be time.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an external view showing a use state of a pizza sauce coating machine according to the present invention. As shown in FIG. 1, the pizza sauce coating machine 1 includes a main body 2 in which a rotational drive source 10 is housed, a power on / off switch 3 that rotates the rotational drive source 10, a rotary shaft 4 of the rotational drive source 10, and coating. The plate 5, the ring-shaped frame body 6, the handles 7 provided on the left and right sides, and the urging means 8 provided so as to be suspended from the support member 19 provided above the belt conveyor 11. The rotary drive source 10 is supplied by a 100 V power cord 9.

  The pizza crust 12, which is a pizza pie dough, is baked and placed on the belt conveyor 11 and conveyed. In the middle, a predetermined amount of pizza sauce 13 is dropped at the pizza sauce topping unit. Since the pizza sauce 13 is viscous, it is a lump in the center of the pizza crust. The conveying speed of the belt conveyor 11 is a constant speed of 4 seconds / sheet in this embodiment. When the conveyance speed is slower than 5 seconds / sheet, it is not necessary to manually apply pizza sauce and introduce a pizza sauce coating machine. If the conveyance speed is increased to 2 seconds / sheet due to production capacity, the sauce coating time of this pizza sauce coater will be about 1 second. In addition, it is difficult to cover the moving pizza crust 12 with the frame 6 of the pizza sauce coating machine. In addition, it can also be made to stop conveyance during pizza sauce coating and to move the belt conveyor 11 intermittently. In that case, the production capacity becomes a value considering the stop time.

  The operator of the pizza sauce coating machine 1 holds the left and right handles 7 and lowers the suspended body body 2 downward so as to surround the area where the pizza sauce is applied on the upper surface of the pizza crust 12 conveyed by the belt conveyor 11 with the frame body 6. Push. As a result, the spring of the urging means 8 extends and the main body 2 can be landed on the upper surface of the pizza crust 12. At the same time, since the coating plate 5 rotates so as to revolve around the rotation axis 4, it can be applied so as to come into contact with the pizza sauce 13 and to uniformly stretch the pizza sauce in the upper surface circumferential direction of the pizza crust. The force for pressing the main body 2 against the pizza crust does not require a large force because the restoring force of the biasing means 8 is balanced with the main body 2, but depends on the skill of the operator.

  The time for applying the pizza sauce 13 by pressing the main body 2 against the top surface of the pizza crust was about 2 seconds / sheet at half the conveyance speed of 4 seconds / sheet. During this 2 seconds, the pizza crust 12 moves from the left side to the right side in FIG. 1, and the urging means 8 can also move to the right following this movement. The remaining 2 seconds can be set as the positioning time or return time of the pizza sauce coating machine 1. If the time for applying the pizza sauce 13 is 3 seconds, the positioning and returning time is 1 second, and the operator is burdened. The support member 19 may be rotatable in order to shorten the return time. The rotational speed of the rotational drive source 10 was such that the top surface of the pizza crust was applied in 2 seconds. During this time, the application plate was rotated twice, and a low-speed gear motor of 60 rpm was used. When the pizza sauce is applied to the surface of the pizza crust 12, when the force pushing downward of the handle 7 is loosened, the main body 2 is lifted upward by the restoring force of the urging means 8.

  FIG. 2 is a plan view showing the movement of the application plate. As shown in FIG. 2, the coating plate 5 has a diameter slightly larger than the radius of the frame body 6. The application plate 5 is connected to the rotating shaft 4 by the connecting link 14 and revolves around the center of the pizza crust 12 in the same manner when the rotating shaft 4 is rotated in the clockwise direction. The application plate 5 is pivotally supported by a shaft 15 at one end of the connection link 14. And since the side close | similar to the frame 6 of the bottom face of the application | coating board 5 is contacted with the pizza crust 12 more strongly than the side of the rotating shaft 4, it rotates in the counterclockwise direction by the resistance. Such a self-rotating method can simplify the mechanism because no special pulley or belt is required. In addition, when the viscosity of the pizza sauce is quite high, a mechanism for positive rotation can be provided.

  FIG. 3 is a cross-sectional view showing the internal structure of the main body 2. As shown in FIG. 3, a rotation drive source 10 is accommodated in the main body 2. A gear that reduces the rotation speed to a specified ratio is mounted below the rotation drive source 10. The frame 6 is provided with a ring-shaped cover 16 on the inner upper part so that the pizza sauce does not jump out of the upper part of the frame 6. The connecting link 14 is inclined toward the application plate 5, and this inclination creates an inclination of the application plate 5. Several types of link links 14 with different inclination angles are prepared and can be exchanged as necessary. In addition, the main body 2 can be separated into upper and lower parts by removing a screw at a part AB. The lower part can be cleaned when the pizza sauce application is finished, so the machine can be kept clean at all times.

  As shown in FIG. 3, the coating plate 5 is attached to the lower side of the frame body 6 and inclined to the rotary shaft 4 side. Thereby, rotation becomes possible and the pizza sauce 13 in the shape of rising at the central portion dripped at the pizza sauce topping portion can be applied so as to be lowered around the pizza crust 12. Here, since the diameter of the frame 6 is 20 cm, the diameter of the coating plate 5 is 10 cm, which is half of the diameter. The diameter of the frame is determined by the diameter of the pizza crust. The diameter of the coating plate 5 should just be 1/2 or more of the diameter of a frame, and 3/4 or less is desirable. The inclination of the coating plate 5 was set to be approximately 2 cm higher than the horizontal direction of 10 cm. If there is no inclination, the direction of rotation is determined by the contact resistance between the coating plate 5 and the pizza crust. When the coating plate 5 is greatly inclined, the central pizza sauce is not stretched to the peripheral side. The length of the shaft 15 is fixed so that the bottom surface of the coating plate 5 does not protrude downward from the bottom surface of the frame body 6. Since the ring-shaped frame 6 is brought into contact with the pizza crust, the pizza sauce 13 does not scatter from the bottom to the outside.

FIG. 4 is a side view of the application plate 5. As shown in FIG. 4, three vertical and horizontal grooves 17 are formed in the center of the bottom surface of the coating plate 5 so as to be orthogonal to each other within a circular range surrounded by a diameter of about ½ of the coating plate diameter. . A longer groove extending to the outer peripheral edge of the coating plate may be formed. In addition, the outer peripheral portion on the bottom surface side of the coating plate 5 is inclined rather than at a right angle so that a gap is formed when it comes into contact with the pizza sauce 13. The pizza sauce 13 can be caught here.
The material of the coating plate 5 was polyacetal, which is one of engineering plastics. Polyacetal has a good balance of mechanical properties and is excellent in chemical resistance and heat resistance. In addition, the coefficient of friction is small and pizza sauce is difficult to adhere.

  FIG. 5 is a front view of the bottom surface of the coating plate 5. As shown in FIG. 5, the groove 17 of the coating plate 5 is provided so as to be orthogonal to the vertical direction and the horizontal direction. This groove 17 is in contact with the pizza sauce and acts to stir the pizza sauce. In addition, since the coating plate 5 is inclined toward the rotating shaft 4, the pizza sauce caught in the groove 17 is stretched toward the frame body 6 by centrifugal force due to rotation.

  FIG. 6 is a plan view of a pizza pie manufacturing system according to the present invention. As shown in FIG. 6, the pizza pie production line is configured as an integrated line connected to a belt conveyor from the formation of dough to packaging. The pizza crust molding unit 20 is composed of pizza crust molding equipment from pizza dough. Pizza dough is produced by mixing raw materials, mixing, kneading, and rolling into balls.

  The pizza crust stretcher 21 is a place where the ball-shaped dough is stretched by the rollers 30 disposed on the belt conveyor 11. The heating unit 22 is configured by an oven, and bakes the pizza crust at a temperature of about 400 ° C. for about 1 minute, for example. In the pizza sauce topping unit 23, a predetermined amount of pizza sauce is dropped onto the upper surface of the pizza crust.

  The pizza sauce coating unit 24 includes the pizza sauce coating machine 1 and is operated by an operator so that the dropped pizza sauce is stretched to the top surface of the pizza crust. In the topping unit 25, cheese topping is performed. Cheese is prepared on the cooking table 31. The packaging unit includes an interior packaging machine 26 for wrapping the pizza crust, a weighing machine 27, and an exterior packaging machine 29 for storing in a bag. Note that when the packed pizza is immediately frozen and transported, for example, a spiral freezer 28 may be provided. The spiral freezer 28 can freeze or cool (chill) the pizza crust while being placed on the belt conveyor.

  The pizza sauce coating machine according to the present invention can apply the pizza sauce on the top surface of the pizza crust quickly and uniformly by the operation of the operator. Also, the quality of pizza sauce coating can be stabilized. Furthermore, it can be used by being incorporated in a production line for conveying a belt conveyor, and is suitable for a medium-scale pizza pie manufacturing system.
