Description

Technical Field

[0001] This invention relates to the field of food production and processing, and in particular to a device for separating raw materials. Background Technology

[0002] Pastry products are a combination of noodles and desserts. Among pastry products with a concave structure, egg tarts are a common example. The crust of an egg tart is a typical edible product with a concave structure. To achieve this concave structure, it is usually made by stamping with a die. However, the crust obtained by stamping is relatively dense, and after baking, the egg tart crust lacks layering and crispness, resulting in poor taste and quality.

[0003] Therefore, to address the above shortcomings, a separating device is needed to improve the layering of the tart crust and thus enhance the taste. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding device that controls the feeding element to feed the dough in a moving or oscillating manner, and drives the base plate where the feeding element is located or the cup used to place the dough to rotate, thereby completing the fully automatic rotation feeding of the tart crust. The rotation feeding method replaces the existing stamping method, reduces the compactness of the tart crust caused by the stamping method, and improves the layering and crispness of the tart crust after baking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding device includes at least one feeding unit, which includes a feeding element, a feeding mechanism, and a rotating mechanism. The feeding element is a device for feeding material. The feeding mechanism controls the relative movement between the feeding element and the blank, thereby pushing the blank located on the inner side outward by means of the relative movement, so that the middle of the blank forms a concave structure. The rotating mechanism drives the feeding element or a cup for placing the blank to rotate. The feeding mechanism drives the feeding element to perform feeding action. If the rotating mechanism drives the feeding element to rotate, the feeding element can perform both rotation and feeding actions. If the rotating mechanism drives the cup to rotate, the feeding element only performs feeding action, and the rotation action is completed by the cup below.

[0007] Accordingly, an anti-sticking mechanism is provided to prevent the blank from sticking to the feeding element. The anti-sticking mechanism includes at least one of an isolation unit, a heating unit, a wetting unit, and a coating unit. The isolation unit is a device that prevents the feeding element from having continuous contact with the blank during feeding. The heating unit is a device that can raise the surface temperature of the feeding element. The wetting unit is a device that can keep the surface of the feeding element in a wet state. The coating unit is an anti-sticking coating applied to the surface of the feeding element.

[0008] Correspondingly, at least the side and end faces of the feeding element used to contact the blank are arc-shaped; thereby obtaining the tart crust on the inner side of the arc and improving the smoothness of feeding.

[0009] Accordingly, the actuating mechanism includes a first position adjustment mechanism, which includes a three-axis mobile device. The first position adjustment mechanism controls the actuating element to perform a actuating action, so that a concave structure is formed in the middle of the blank.

[0010] Accordingly, the actuating mechanism includes a base plate and a transverse unit. The base plate is fixedly installed, the transverse unit is installed on the base plate, and the material actuating element is installed on the transverse unit. The material actuating element is driven to move relative to the blank through the transverse unit.

[0011] Accordingly, the transverse unit includes a rotary drive source and a conversion unit, the rotary drive source and the conversion unit are drivenly connected, the conversion unit converts the rotary motion of the rotary drive source into linear motion, and the conversion unit includes any one of a gear and rack type conversion mechanism, a crank type conversion mechanism, a cam type conversion mechanism and a screw type conversion mechanism, and the feeding element is provided on the conversion unit;

[0012] Accordingly, the gear and rack conversion mechanism includes a gear and a rack. A rotary drive source is provided on the base plate, and a gear that rotates with the drive shaft of the rotary drive source is provided on the drive shaft of the rotary drive source. The rack is meshed and connected with the gear, and a material-feeding element that moves with the rack is provided on the rack. The gear rotates in both forward and reverse directions under the drive of the rotary drive source, thereby driving the rack to reciprocate linearly, which in turn drives the material-feeding element to move relative to the blank, thus realizing material feeding.

[0013] Correspondingly, the rack is provided with two racks, which are located on opposite sides of the gear. The feeding element that moves with the rack is provided on each of the two racks. The gear rotates in both directions under the drive of the rotary drive source. The racks on both sides move under the meshing transmission with the gear. When the gear rotates in the forward direction, the two racks move towards each other. When the gear rotates in the reverse direction, the two racks move away from each other, thereby driving the two feeding elements to open and close to feed the material.

[0014] Accordingly, the lateral movement unit includes a moving module or a telescopic structure, and the feeding element is fixedly installed on the moving block of the moving module or the telescopic end of the telescopic structure; the lateral movement of the lateral movement unit drives the feeding element to move, thereby realizing the feeding element's movement and feeding.

[0015] Correspondingly, the lateral movement unit includes a telescopic structure and an auxiliary frame. The telescopic structure is movably mounted on the base plate, and the auxiliary frame is fixedly mounted on the base plate. A swing structure is rotatably connected to the telescopic rod on the telescopic structure and the auxiliary frame, respectively. The swing structure swings by means of the telescopic connection point between the telescopic structure and the auxiliary frame. The end of the swing structure is provided with a material feeding element that is separate from or integrated with the swing structure. The integrated configuration is directly installed, while the separate configuration is installed through an intermediate structure such as a connecting rod. The rotational connection point with the auxiliary frame serves as the swing point of the material feeding element, allowing the material feeding element to swing under the drive of the moving module or the telescopic structure, thereby increasing the material feeding range of the material feeding element.

[0016] Accordingly, the feeding unit also includes a guiding structure, which guides the linear motion in the feeding mechanism;

[0017] Correspondingly, the base plate is fixedly mounted on the rotating mechanism, and the rotating mechanism drives the base plate to rotate; the rotating mechanism drives the base plate to rotate, and the rotation of the base plate drives the rotation of the structure on it, that is, drives the rotation of the guide structure and the rack or transverse unit, thereby realizing the rotation of the feeding element. The feeding element can realize both rotation and feeding actions.

[0018] Correspondingly, a second position adjustment mechanism is driven and connected to the feeding unit. The second position adjustment mechanism is used to compensate for the position movement driven by the feeding mechanism. The second position adjustment mechanism includes a three-axis moving device. Under the premise that the feeding element has achieved feeding, the three-axis moving mechanism is used to drive the feeding element to rise and fall, and to optimize the trajectory of the feeding element's lateral feeding.

[0019] Accordingly, multiple feeding units are provided, and the feeding mechanisms among the multiple feeding units are set synchronously.

[0020] The beneficial effects of this invention are as follows:

[0021] By controlling the feeding element to feed the dough in a moving or oscillating manner, and driving the base plate where the feeding element is located or the cup used to place the dough to rotate, the fully automatic rotation feeding of the tart crust is completed. The rotation feeding method replaces the existing stamping method, reducing the problem of the tart crust being too dense caused by the stamping method, and improving the layering and crispness of the tart crust after baking.

[0038] In the description of this invention, it should be understood that the terms used to indicate orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0039] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0040] The feeding device includes at least one feeding unit; in this embodiment, one feeding unit will be used for description. The feeding unit includes a feeding element 1, a feeding mechanism, a rotating mechanism, and a guiding structure.

[0041] The feeding element 1 is a device used for feeding material. Therefore, at least the side and end faces of the feeding element 1 that are in contact with the blank are arc-shaped surfaces. The arc shape of the arc-shaped surfaces is set according to the inner shape of the desired tart crust. Taking the feeding element 1 as a finger structure as an example, if the feeding element 1 is a complete structure, then the feeding element 1 as a whole is a finger structure, that is, it includes a long cylindrical structure and a hemispherical structure located at the lower end of the long cylindrical structure. If the feeding element 1 includes several (e.g., two), then the two feeding elements 1 can form the aforementioned finger structure when they are joined together. An anti-sticking mechanism is used to prevent the blank from sticking to the feeding element 1. The anti-sticking mechanism includes at least one of an isolation unit, a heating unit, a wetting unit, and a coating unit. The isolation unit refers to a device that prevents the feeding element 1 from continuous contact with the blank during feeding. A typical example is the ultrasonic heater 2. When ultrasound acts on the blank, it generates high-frequency vibrations of tens of thousands of times per second. This high-frequency vibration, reaching a certain amplitude, transmits ultrasonic energy to the feeding contact surface. The high acoustic impedance at the contact surface generates localized high temperatures; therefore, the ultrasonic heater also incorporates the performance of the heating unit. The heating unit refers to a device that raises the surface temperature of the feeding element 1. High temperatures melt the oily substances on the blank surface, reducing the blank's stickiness. Besides the aforementioned ultrasonic heater, heating coils are commonly used. The wetting unit refers to a device that ensures the surface of the feeding element 1 remains moist, for example, by wiping the feeding element 1 with a damp sponge. The coating unit refers to the anti-stick coating applied to the surface of the feeding element 1. A common anti-stick coating is the polytetrafluoroethylene coating applied to the inside of the pot.

[0042] The actuating mechanism controls the relative movement between the feeding element and the blank. In this embodiment, the actuating mechanism is used to drive the feeding element to move. Therefore, it can also be understood that the actuating mechanism is used to drive the feeding element to move or swing in the radial direction of the blank. By means of this movement or swing, the blank located on the inner side is pushed to the outer side, so that the middle part of the blank forms a concave structure. The rotating mechanism drives the feeding element 1 or the cup used to place the blank to rotate. The guide structure 42 guides the linear movement in the actuating mechanism. The guide structure 42 can be set according to the guidance requirements.

[0043] Example 1

[0044] like Figure 1As shown, the actuating mechanism includes a first position adjustment mechanism 3, which comprises a three-axis mobile device, such as a three-axis robot. The three-axis robot drives the actuating element 1 to perform a actuating action, causing a concave structure to form in the center of the blank. For example, the three-axis robot controls the actuating element 1 to move radially around the center of the blank's cross-section. After completing one radial movement, it returns to the midpoint position and adjusts its position before performing the next adjacent radial movement, completing at least one full rotation of radial movement. Furthermore, arc trajectory adjustment can be incorporated into the radial movement. Using a three-axis robot for movement trajectory control is a relatively mature technology; only the corresponding parameters need to be entered as needed. Therefore, this embodiment will not provide a detailed description of the three-axis robot's movement trajectory control.

[0045] In this embodiment, the anti-sticking mechanism is set as an ultrasonic heater 2, which is connected to the material feeding element 1 (the transducer on the ultrasonic heater 2 is shown in the figure, used to refer to the ultrasonic heater 2). The rotation mechanism is a geared motor, referred to as the second geared motor 81 (hereinafter the same). Given the presence of the ultrasonic heater 2, in order to make the installation position of the second geared motor 81 and the position of the ultrasonic heater 2 staggered, the second geared motor 81 drives the material feeding element 1 to rotate through a transmission mechanism. For example, a synchronous belt transmission mechanism 82 is used, with a driving wheel installed on the output shaft of the second geared motor 81. The driving wheel and the driven wheel are connected by a synchronous belt transmission. The fixing plate for installing the material feeding element 1 is fixedly installed on the driven wheel. The driven wheel drives the fixing plate to rotate, thereby driving the material feeding element 1 to rotate.

[0046] Example 2

[0047] like Figure 2-5 As shown, the actuating mechanism includes a base plate 41, a transverse unit, and a guide structure 42. The base plate 41 is fixedly mounted on the second reduction motor 81. A transverse unit is mounted on the base plate 41, and a feeding element 1 is mounted on the transverse unit. The transverse unit drives the feeding element 1 to move relative to the blank. Figure 1-3 As shown, both the transverse unit and the second reduction motor 81 are used to drive the feeding element 1, so as to realize the movement and rotation of the feeding element 1.

[0048] The transverse unit includes a rotary drive source and a conversion unit, which are connected in a drive connection. In this embodiment, the rotary drive source is a geared motor, which is referred to as the first geared motor 51 for easy distinction. The conversion unit converts the rotational motion of the first geared motor 51 into linear motion, and a feeding element 1 is provided on the conversion unit.

[0049] There are many conversion units that convert rotary motion into linear motion, which can be divided into four main categories: 1) rack and pinion conversion mechanism; 2) crank conversion mechanism, which includes a crank and a guide rod. The crank is rotated by a first geared motor 51, and the rotation of the crank drives the guide rod to move linearly. The combination of a disc and a connecting rod, and the anti-rotation yoke are typical crank conversion mechanisms; 3) cam conversion mechanism, which includes a cam, a driven rod, and an elastic return element. The cam is rotated by a first geared motor 51, and the elastic return element presses one end of the driven member against the rim of the cam. The driven member moves linearly under the push of the cam; 4) screw conversion mechanism, which includes a screw, a nut, and a slide rod. The screw is rotated by a first geared motor 51, which drives the nut to move linearly on the slide rod.

[0050] In this embodiment, the conversion unit is described using a rack and pinion conversion mechanism as an example. This mechanism includes a gear 52 and a rack 53. A first reduction motor 51 and a guide structure 42 are fixedly mounted on the base plate 41. The gear 52, which rotates with the drive shaft of the first reduction motor 51, is fixedly mounted on the drive shaft. The rack 53 is meshed and connected to the gear 52. The guide structure 42 guides the movement of the rack 53. To improve processing efficiency, the rack 53 is not limited to one; preferably, two racks are used. The two racks 53 reciprocate, moving towards and away from each other. The other conversion mechanisms described above are similar and will not be repeated below.

[0051] In this embodiment, two racks 53 are provided, located on opposite sides of the gear 52. Feeding elements 1, which move with the racks 53, are respectively provided on each rack 53. In this embodiment, the guide structure 42 and the base plate 41 are assembled into a hollow cuboid structure. The guide structure 42 is fixedly mounted on the base plate 41. Guide grooves are provided on the two side walls of the guide structure 42 corresponding to the two racks 53. The racks 53 are slidably disposed within the guide grooves. Furthermore, since the feeding elements 1 are fixedly mounted on the lower side of the racks 53, the lower side of the guide structure 42 is also provided with clearance holes, such as elongated holes, for the lateral movement of the feeding elements 1. Due to the presence of the first reduction motor 51, in order to offset the installation position of the second reduction motor 81 from that of the first reduction motor 51, the second reduction motor 81 drives the base plate 41 to rotate via a transmission mechanism. For example, a synchronous belt drive mechanism 82 is used, with a drive wheel mounted on the output shaft of the second geared motor 81. The drive wheel and the driven wheel are connected by a synchronous belt drive. The base plate 41 is fixedly mounted on the driven wheel, which drives the base plate 41 to rotate. The driven wheel also has a through hole for the drive shaft of the first geared motor 51 to pass through. Thus, the forward and reverse rotation of the first geared motor 51 drives the gear 52 to rotate in the forward and reverse directions. The meshing of the gear 52 and the rack 53 drives the rack 53 to reciprocate, thereby driving the material-feeding element 1 mounted on the rack 53 to open and close, achieving material feeding. Simultaneously, the second geared motor 81 and the synchronous belt drive mechanism 82 drive the base plate 41 to rotate, thereby driving the guide structure 42 and the rack 53 to rotate, and intermittently driving the rotation of the material-feeding element 1 on the rack 53, achieving adjustment of the material feeding position. This realizes the material feeding and rotation actions of the material-feeding element 1.

[0052] It should be noted that this embodiment is based on a single feeding unit. In a testing machine or a small production line, a single feeding unit can be controlled independently. If multiple feeding units are set up, or in a large production line, multiple feeding units can feed materials synchronously. In this case, for ease of setup, the second reduction motor 81 does not drive the rotation of the base plate 41, but instead drives the rotation of the cup body below the feeding element 1 used to place the blank, avoiding interference between synchronous movement and rotation. For example, continuing with the gear and rack conversion mechanism, the racks 53 located on the same row are connected into one rack 53. Whether it is two racks 53 in the same feeding unit or two racks 53 in different feeding units, they are connected by gear 52 meshing transmission. Then, the first reduction motor 51 drives any one of the gears 52, and the second reduction motor 81 drives the cup body to rotate, which is the method of embodiment six.

[0053] Furthermore, since only linear motion can be obtained using the conversion unit, a second position adjustment mechanism 54 can be driven and connected to the mounting plate for mounting the second geared motor 81 to provide arc-shaped trajectory support for the linear motion. For example, a three-axis robot can be used to realize the raising and lowering of the feeding unit and provide arc-shaped trajectory support for the lateral feeding of the feeding element 1. Subsequent embodiments are similar, and a three-axis robot can also be set up, which will not be described in detail below.

[0054] Example 3

[0055] Similar to Embodiment 2, both the actuating mechanism and the rotating mechanism are used to drive the feeding element 1. The difference lies in the lateral movement unit on the actuating mechanism. The lateral movement unit is a moving module or a telescopic structure, with the feeding element 1 fixedly mounted on the moving block of the moving module or the telescopic end of the telescopic structure. In this embodiment, a moving module is used, such as a micro moving motor module 61.

[0056] Following on from the previous text, such as Figure 6 and 7 As shown, the actuating mechanism includes a base plate 41, a micro-moving motor module 61, and a guide structure 42. The base plate 41 is also driven by a second reduction motor 81. Since this embodiment uses a moving module, there is no need to set a first reduction motor 51, and there is no conflict in the installation positions of the second reduction motor 81 and the first reduction motor 51. Therefore, the base plate 41 can be directly and fixedly connected to the output shaft of the second reduction motor 81. To simplify the drawing, this embodiment does not change the installation position of the second reduction motor 81 or the driving method of the base plate 41. A micro-moving motor module 61 and a guide structure 42 for guiding the micro-moving motor module 61 in the lateral direction are set on the base plate 41. A feeding element 1 is fixedly installed on the moving block of the micro-moving motor module 61. The feeding element 1 is moved by the moving block on the micro-moving motor module 61 to realize the movement and feeding of the feeding element 1. Similarly, if two feeding elements 1 need to move in opposite directions or in opposite directions, a bidirectional synchronous moving module or two sets of moving modules can be used. The guide structure 42 is fixedly mounted on the base plate 41 and located on one side of the micro-mobile motor module 61. For example, it serves as an auxiliary guide rail structure to improve the stability of the micro-mobile motor module 61's guidance. Thus, the lateral movement of the micro-mobile motor module 61 drives the feeding element 1 to reciprocate, achieving feeding. Simultaneously, the second reduction motor 81 drives the base plate 41 to rotate, thereby causing the guide structure 42 and the micro-mobile motor module 61 to rotate, and consequently, the feeding element 1 to rotate, adjusting its feeding position. This achieves the feeding and rotational actions of the feeding element 1.

[0057] Example 4

[0058] Similar to Embodiment 3, both use a lateral movement unit and a second reduction motor 81 to move and drive the material-feeding element 1. The difference is that the lateral movement unit is only applicable to telescopic structures, and the movement of the material-feeding element 1 is not a linear movement but a swinging movement. In this embodiment, the lateral movement unit is set as a telescopic structure, such as a telescopic electric cylinder 41.

[0059] Following on from the previous text, such as Figure 8 As shown, a telescopic electric cylinder 71 (which can also be a pneumatic cylinder, hydraulic cylinder, etc.), a guide structure 42, and an auxiliary frame 72 are hingedly mounted on the base plate 41. A connecting block 73 is fixedly mounted on the telescopic end of the telescopic electric cylinder 71. The guide structure 42 is a groove or guide rail set on the base plate 41 for guiding the connecting block 73. The auxiliary frame 72 has a three-sided structure resembling a door frame. Two ends of the three-sided structure are fixedly mounted on the base plate 41, so that the three-sided structure and the base plate 41 form a square. A hinged mounting seat is provided on one side of the three-sided structure parallel to the base plate 41. The material-feeding element 1 is hingedly mounted on the connecting rod 74. The upper end of the connecting rod 74 is hinged to the telescopic end of the telescopic electric cylinder 71, and the middle section of the connecting rod 74 is hinged to the auxiliary frame 72 through the hinged mounting seat. Thus, the hinge point between the material-feeding element 1 and the auxiliary frame 72 serves as the swing point of the material-feeding element 1, causing the material-feeding element 1 to swing under the drive of the telescopic electric cylinder 71, thereby increasing the material-feeding range of the material-feeding element 1. The second reduction motor 81 drives the base plate 41 to rotate, which in turn drives the feeding element 1 to rotate, thereby realizing the feeding and rotation actions of the feeding element 1.

[0060] Example 5

[0061] The difference between this and Embodiment 1 is that the actuating mechanism is used to drive the feeding element 1, that is, the three-axis robot drives the feeding element 1 to perform feeding action, but the rotating mechanism acts on the cup body, that is, the second reduction motor 81 is used to drive the rotation of the cup body, and the driving method is the same as the driving of the base plate 41.

[0062] Example 6

[0063] The difference between this embodiment and embodiment 2 is that the conversion unit is used to drive the feeding element 1, but the rotation mechanism acts on the cup body, that is, the second reduction motor 81 is used to drive the rotation of the cup body, and the driving method is the same as that for the bottom plate 41.

[0064] Example 7

[0065] The difference between this and Embodiment 3 is that the micro-mobile motor module is used to drive the feeding element 1, but the rotating mechanism is used to drive the cup body. That is, the second reduction motor 81 is used to drive the rotation of the cup body, and the driving method is the same as that for the base plate 41.

[0066] Example 8

[0067] The difference between this and embodiment four is that the telescopic electric cylinder 71 is used to drive the feeding element 1, but the rotating mechanism is used to drive the cup body, that is, the second reduction motor 81 is used to drive the rotation of the cup body, and the driving method is the same as that for driving the base plate 41.

[0068] Based on the structure described in Example 2, the following implementation method can be obtained:

[0069] A cylindrical dough is placed vertically in a cup located below the feeding element. A three-axis robot lowers the feeding unit, and the feeding element is inserted into the center of the dough (or a hole can be pre-drilled in the center of the dough). Driven by the forward and reverse rotation of the first reduction motor 51, the two racks 53 reciprocate (moving in opposite directions and towards each other) under the meshing transmission of the gear 52, driving the two feeding elements 1 that are joined together to open and close cyclically, realizing feeding. At the same time, the second reduction motor 81 drives the base plate 41 to rotate through the synchronous belt transmission mechanism 82. The base plate 41 drives the racks 53 on the base plate 41 to rotate, thereby driving the feeding elements 1 set on the racks 53 to rotate. Thus, the rotation and feeding actions are realized at the same time, feeding the dough into the shape of an egg tart crust. After feeding is completed, the first reduction motor 51 and the second reduction motor 81 stop working, and the lifting mechanism drives the feeding unit to rise, which facilitates the removal of the tart crust and the insertion of the next dough.

[0070] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
