Description

Technical Field

[0001] The invention relates to the technical field of food processing equipment, in particular to a cake embryo engraving machine. Background Art

[0002] Cake base preparation is a basic step in cake making. For example, cheesecake base is the basis for making cheesecake. Cake base is usually formed in a rectangular mold. In mass production, the whole cake base needs to be transported to the corresponding stamping mechanism, which is punched into multiple small cake base bodies, such as a cake engraving machine disclosed in patent announcement number: CN217695105U.

[0003] In the traditional cake embryo carving process, after the whole cake embryo is punched into multiple small cake embryos by a punching mechanism, multiple small cake embryos need to be adsorbed by multiple suction nozzles on the suction and discharge conveying mechanism and placed on the engraved mold cavities of the cake engraved mold (the number of suction nozzles corresponds to the number of engraved mold cavities); then the pushing mechanism pushes each cake embryo into each engraved mold cavity of the cake engraved mold, and finally the pushing mechanism continues to push the cake embryo in the engraved mold cavity to complete the engraving of the cake embryo. When each cake embryo is engraved through each engraved mold cavity of the cake engraved mold, it falls onto the conveyor belt below the cake engraved mold and is output by the conveyor belt. Finally, the suction and discharge conveying mechanism adsorbs each cake embryo output by the conveyor belt and places it into the cake embryo tray. However, there are the following defects in the cake embryo carving process:

[0004] First, in the process of the conveyor belt outputting the cake embryos after each engraving, the cake embryos will be offset on the conveyor belt due to the transmission of the conveyor belt, that is, the cake embryos will not be output along a straight line on the conveyor belt. This will make it difficult for the suction nozzles on the suction and discharge conveying mechanism to align with each cake embryo, thereby making it difficult for the suction and discharge conveying mechanism to absorb and grab each cake embryo output by the conveyor belt at one time and place it in the cake embryo tray, affecting production efficiency.

[0005] Secondly, placing the cake embryo body after engraving by the suction and discharge conveying mechanism in the cake embryo tray will also cause the cake embryo body to deform, affecting the molding effect of the cake embryo body.

[0006] Third, in the process that the multiple suction nozzles of the suction and discharge conveying mechanism suck and move the multiple cake embryos punched out by the punching mechanism to the cake embryo mold, the cake embryos are easily thrown off due to the movement of the suction nozzles.

[0007] One of the purposes of the present invention is to provide a cake embryo engraving machine, which can effectively prevent the suction and discharge conveying mechanism from adsorbing and grabbing the cake embryos output by the conveyor belt after the engraving is completed and placing them in the cake embryo tray, thereby preventing the suction and discharge conveying mechanism from having difficulty in adsorbing and grabbing each cake embryo output by the conveyor belt and placing it in the cake embryo tray at one time, and at the same time preventing the cake embryo from being deformed after engraving.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] When the cake embryo engraving machine of the present invention is in use, the adsorption and feeding unit is driven by the mechanical arm to move to the top of the cake embryo to be processed, and then the lifting unit is used to drive each suction nozzle to extend out of the forming mold cavity to adsorb and grab a piece of cake embryo to be processed; then, the adsorption and feeding unit is driven by the mechanical arm to move to the top of the cake embryo mold plate, and each forming mold cavity is aligned with each mold hole on the cake embryo mold plate one by one, and the cake embryo to be processed adsorbed by the suction nozzle is placed on the upper surface of the cake embryo mold plate, and the mechanical arm presses the lower surface of each forming mold cavity on the upper surface of the cake embryo, and at this time, the lifting unit drives each suction nozzle to rise to the top of each forming mold cavity; then, the lifting mechanism drives each forming convex mold to rise into each forming mold cavity to punch and cut the whole cake embryo placed on the cake embryo mold plate into multiple small cake embryo bodies, and at this time, the lifting unit drives each suction nozzle to descend and adsorb the cake embryo bodies in each forming mold cavity; then, the machine The mechanical arm drives the adsorption and feeding unit to move above the cake engraved mold, and aligns each engraved mold cavity on the cake engraved mold with each forming mold cavity one by one, at which time the lower surface of each forming mold cavity is pressed against the upper surface of the cake engraved mold; then, the lifting unit drives each suction nozzle to descend, and pushes each cake embryo adsorbed on each suction nozzle into each engraved mold cavity. At this time, the cake embryo tray is directly below the cake engraved mold, and each embryo receiving sleeve on the cake embryo tray is aligned with the engraved mold cavity on the cake engraved mold one by one, and the upper port of the embryo receiving sleeve is connected and communicated with the lower port of the engraved mold cavity; since the embryo receiving sleeve has the same shape as the engraved mold cavity, and the outer diameter of the suction nozzle is smaller than the inner diameter of the engraved mold cavity, the lifting unit is continued to drive each suction nozzle to descend, so that the cake embryo in each engraved mold cavity can be pushed into each embryo receiving sleeve on the cake embryo tray, so that the engraving of the cake embryo can be completed; finally, the driving unit drives the conveying chain to output the cake embryo tray.

Finally, the driving unit drives the conveyor chain to output the cake embryo tray, which effectively avoids the suction and discharge conveying mechanism from sucking and grabbing the cake embryo body after the engraving is completed and placing it in the cake embryo tray, thereby avoiding the cake embryo body from being offset on the conveyor belt due to the transmission of the conveyor belt, and then effectively avoiding the suction and discharge conveying mechanism from being difficult to suck and grab each cake embryo body output by the conveyor belt at one time and place it in the cake embryo tray, and at the same time avoiding the deformation of the cake embryo body after engraving.

[0027] 2. The present invention provides a cake embryo tray with a embryo receiving sleeve that can be connected with and communicated with the lower end of the embryo engraving mold cavity, so that the cake embryo body after the embryo engraving is completed will not be damaged during the process of entering the cake embryo tray from the embryo engraving mold cavity, thereby improving the molding effect of the cake embryo body after the embryo engraving is completed.

[0028] 3.

[0029] 4. In the process of the suction nozzle sucking and moving the multiple cake embryos that have been punched out to the cake engraved mold, since each cake embryo is located in each forming cavity on the suction and discharge conveying mechanism, the forming cavity plays the role of limiting the cake embryo, preventing the cake embryo from being easily thrown off due to the movement of the suction nozzle, thereby improving the stability of the suction nozzle in conveying the cake embryo.

The cake embryo mold plate 33 is fixed on the fixed seat 30 through a connecting column, and the cake embryo mold plate 33 is located above the plurality of forming convex molds. Of course, the cake embryo mold plate 33 is provided with a plurality of mold holes 330 that penetrate the relative surface of itself, and the plurality of mold holes 330 are aligned one by one with the plurality of forming convex molds 32. Under the driving force of the lifting mechanism 34, each forming convex mold 32 slides through each mold hole 330.

[0050] Reference Figure 1 , Figure 2 and Figure 4The cake engraving mold 4 is fixed on the frame 1 and is located above the conveying chain 21 . The cake engraving mold 4 is provided with a plurality of engraving mold cavities 421 for engraving, and the number of the plurality of engraving mold cavities 421 is the same as the number of the plurality of mold holes 330 .

[0051] Reference Figure 1 and Figure 2 , the cake embryo tray 5 is placed on two conveyor chains 21 on both sides along the width direction of the frame 1, and a guide structure (not shown) is arranged between the cake embryo tray 5 and the frame 1, and the guide structure can be a guide groove arranged on the frame 1 along the length direction of the frame 1 and a slide bar arranged on both sides of the cake embryo tray 5 along the width direction of the frame 1. Wherein, under the transmission of the conveyor chain 21, the guide structure makes the cake embryo tray 5 be transported in a straight line along the length direction of the frame 1. In addition, a plurality of embryo sleeves 50 are arranged in the cake embryo tray 5, and the embryo sleeves 50 are detachably connected to the cake embryo tray 5, so that different embryo sleeves 50 can be easily replaced. Of course, the plurality of embryo sleeves 50 correspond to the plurality of embryo engraving mold cavities 421 one by one and can be aligned, the embryo sleeve 50 has the same shape as the embryo engraving mold cavity 421, and the upper end of the embryo sleeve 50 can be connected and communicated with the lower end of the embryo engraving mold cavity 421.

[0052] Reference Figure 1 , Figure 2 and Figure 8 - Fig.11The suction and discharge conveying mechanism 6 includes a mechanical arm 60 and an adsorption and feeding unit 61. The adsorption and feeding unit 61 is arranged on the mechanical arm 60. The adsorption and feeding unit 61 includes a connecting seat 611, a lifting unit 612, a plurality of gas delivery columns 613, a plurality of molding cavities 614, a pressing plate 615 and a plurality of suction nozzles 619. The lifting unit 612 is arranged on the mechanical arm 60 and is used to drive the plurality of suction nozzles 619 to rise and fall synchronously. Specifically, the connecting seat 611 is fixed to the free end of the mechanical arm 60 (referring to the end effector of the mechanical arm 60), the lifting unit 612 uses a lifting cylinder, and the lifting unit 612 is fixed to the connecting seat 611 in the vertical direction. The lifting end of the lifting unit 612 is driven and connected with a sealing cover 620, and the lower end of the sealing cover 620 is sealed and connected with a cover shell 621, that is, the sealing cover 620 plate covers the upper end of the cover shell 621, so that a sealing cavity 622 is formed between the sealing cover 620 and the cover shell 621. Multiple gas delivery columns 613 correspond to multiple suction nozzles 619 one by one, and the gas delivery columns 613 extend vertically. One end of each gas delivery column 613 is sealed and connected to each suction nozzle 619, and the other end of each gas delivery column 613 is connected to the above-mentioned sealed cavity 622. The sealed cavity 622 is provided with an air inlet 623 and an air outlet 624. The air inlet 623 and the air outlet 624 are sealed and connected to an air inlet bellows (not shown) and an air outlet bellows (not shown). It can be seen that the use of a sealed cavity 622 and multiple gas delivery columns 613 in sealed communication can save the number of air pipes, and at the same time facilitate the control of multiple suction nozzles 619 to rise and fall synchronously. If the above-mentioned sealed cavity 622 is not designed, then each gas delivery column 613 needs to be connected to an air inlet pipe and an air outlet pipe, thereby increasing the number of air pipes.

[0053] Of course, multiple suction nozzles 619 correspond one-to-one to multiple molding cavities 614, each molding cavity 614 is fixed on the connecting seat 611, and each suction nozzle 619 is arranged in each molding cavity 614, so that each suction nozzle 619 can descend from each molding cavity 614 or rise to the outside of each molding cavity 614 under the driving force of the lifting unit 612.

[0054] In addition, the pressing plate 615 is fixed to the connection seat 611 through the fixing column 616. The pressing plate 615 is provided with a plurality of first connection holes 6150 penetrating the opposite surface thereof. The plurality of first connection holes 6150 correspond to the plurality of molding cavities 614 one by one. The shape of the first connection holes 6150 is the same as the shape of the molding cavities 614. The outer diameter of the first connection holes 6150 is larger than the outer diameter of the molding cavities 614. The lower end outer wall of each molding cavity 614 is fitted and fixed to the inner wall of each first connection hole 6150, and the lower end surface of the molding cavity 614 is flush with the lower end surface of the first connection hole 6150. In order to enhance the molding effect of the cake embryo in the molding cavity 614, a transition plate 617 is also fixed between the connection seat 611 and the pressing plate 615. The thickness of the transition plate 617 is larger than the thickness of the pressing plate 615. Of course, the transition plate 617 is provided with a plurality of second connection holes 618 penetrating through its upper and lower surfaces. The plurality of second connection holes 618 correspond one-to-one to the plurality of molding cavities 614. The shape of the second connection holes 618 is the same as that of the molding cavities 614. The upper outer wall of each molding cavity 614 is fitted and fixed to the inner wall of each second connection hole 618.

[0055] Of course, the multiple forming cavities 614 correspond to the multiple forming convex molds 32 one by one and can communicate with each other. The forming cavities 614 are adapted to the forming convex molds 32 so that the whole cake embryo placed on the cake embryo mold plate 33 can be punched into multiple small cake embryos. The multiple suction nozzles 619 correspond to the multiple mold holes 330 one by one. The outer diameter of the suction nozzles 619 is smaller than the inner diameter of the engraved embryo cavity 421. The robot arm 60 can align the multiple suction nozzles 619 with the multiple mold holes 330 one by one. The robot arm 60 can also align the multiple suction nozzles 619 with the multiple engraved embryo cavity 421 one by one. Each suction nozzle 619 is used to absorb and grasp each cake embryo body and move it to the top of the cake engraved embryo mold 4. At the same time, each suction nozzle 619 pushes the absorbed cake embryo body into each engraved embryo cavity 421, so that each cake embryo body can pass through each engraved embryo cavity 421 into each embryo sleeve 50 to complete the engraving.

[0056] When the cake embryo engraving machine of the present invention is in use, the mechanical arm 60 is controlled by the electric control box 92 to drive the adsorption feeding unit 61 to move to the top of the cake embryo to be processed, and then the lifting unit 612 drives each suction nozzle 619 to extend out of the forming mold cavity 614 to adsorb and grab a piece of cake embryo to be processed; the cake embryo to be processed can be placed on a table, and the table is located outside the frame 1; then, the mechanical arm 60 drives the adsorption feeding unit 61 to move to the top of the cake embryo mold plate 33, and each forming mold cavity 614 is aligned with each mold hole 330 on the cake embryo mold plate 33. The cake embryo to be processed adsorbed by the suction nozzle 619 is aligned, and the cake embryo to be processed is placed on the upper surface of the cake embryo mold plate 33. At the same time, the robot arm 60 presses the pressing plate 615 on the upper surface of the cake embryo. At this time, the lifting unit 612 drives each suction nozzle 619 to rise above each forming cavity 614; then, the lifting mechanism 34 drives each forming convex mold 32 to rise into each forming cavity 614 to punch the whole cake embryo placed on the cake embryo mold plate 33 into multiple small cake embryo bodies. At this time, the lifting unit 612 drives each suction nozzle 619 to descend and adsorb on each forming cavity 614. 14; then, the adsorption feeding unit 61 is driven by the robot arm 60 to move to the top of the cake engraved mold 4, and the engraved mold cavities 421 on the cake engraved mold 4 are aligned one by one with the forming mold cavities 614. At this time, the pressing plate 615 is pressed against the upper surface of the cake engraved mold 4; then, the lifting unit 612 drives each suction nozzle 619 to descend, and pushes each cake embryo adsorbed on each suction nozzle 619 into each engraved mold cavity 421. At this time, the cake embryo tray 5 is directly below the cake engraved mold 4, and each embryo sleeve 50 on the cake embryo tray is aligned with the cake engraved mold The engraved mold cavities 421 on the mold 4 are aligned one by one, and the upper end of the embryo receiving sleeve 50 is connected to the lower end of the engraved mold cavity 421; since the embryo receiving sleeve 50 has the same shape as the engraved mold cavity 421, and the outer diameter of the suction nozzle 619 is smaller than the inner diameter of the engraved mold cavity 421, the lifting unit 612 is continued to drive each suction nozzle 619 to descend, so that the cake embryo in each engraved mold cavity 421 can be pushed into each embryo receiving sleeve 50 on the cake embryo tray 5, so that the engraving of the cake embryo can be completed; finally, the driving unit 20 drives the conveying chain 21 to output the cake embryo tray 5.

[0057] In summary, it can be seen that: 1. In the present invention, the cake embryo body sucked by the suction nozzle 619 is pushed into the engraved embryo mold cavity 421 and then directly pushed into the embryo receiving sleeve 50 in the cake embryo tray 5, and finally the driving unit 20 drives the conveying chain 21 to output the cake embryo tray 5, effectively avoiding the suction and discharge conveying mechanism 6 to absorb and grab the cake embryo body after the embryo engraving is completed and place it in the cake embryo tray 5, thereby avoiding the cake embryo body from being offset on the conveyor belt due to the transmission of the conveyor belt, and then effectively avoiding the suction and discharge conveying mechanism 6 from being difficult to absorb and grab each cake embryo body output by the conveyor belt and place it in the cake embryo tray 5 at one time, and at the same time avoiding the deformation of the cake embryo body after engraving.

[0058] 2. The present invention provides a cake embryo tray 5 with a embryo receiving sleeve 50 that can be connected with and communicated with the lower end of the embryo engraving mold cavity 421, so that the cake embryo after the embryo engraving is completed will not be damaged during the process of entering the cake embryo tray 5 from the embryo engraving mold cavity 421, thereby improving the molding effect of the cake embryo after the embryo engraving is completed.

[0059] 3. During use of the present invention, the cake embryo is only adsorbed and grabbed once before carving, which can avoid adsorbing and grabbing the cake embryo after carving, thereby effectively avoiding the suction and discharge conveying mechanism 6 from adsorbing and grabbing the cake embryo after carving for the second time and placing it into the cake embryo tray 5, thereby effectively avoiding deformation of the cake embryo after carving.

[0060] 4. In the process of the suction nozzle 619 sucking and moving the multiple cake embryos that have been punched out to the cake engraved mold 4, since each cake embryo is located in each forming cavity 614 on the suction and discharge conveying mechanism 6, the forming cavity 614 plays a role in limiting the cake embryo, preventing the cake embryo from being easily thrown off due to the movement of the suction nozzle 619, thereby improving the stability of the suction nozzle 619 in conveying the cake embryo.

[0061] It should be noted that the robot arm 60 is a six-axis robot arm 60. The robot arm 60 is a high-precision, multi-input and multi-output, highly nonlinear, and strongly coupled complex system. It is widely used in many fields due to its unique operational flexibility. Since the robot arm 60 is a relatively mature technology in the mechanical field, it will not be described here.

[0062] Of course, a position sensor (not shown) is also provided on the frame 1 , and the position sensor is controlled by the electric control box 92 . The position sensor is used to detect whether the cake embryo tray 5 is directly below the cake embryo mold 4 .

[0063] In one embodiment, referring to Figure 1 , Figure 2 and Figure 4 - Figure 7The cake engraving mold 4 includes an upper template 40, a lower template 41 and an engraving mold sleeve 42. The lower template 41 is arranged on the frame 1, and the upper template 40 is arranged on the upper surface of the lower template 41. The upper template 40 and the lower template 41 can move relative to each other along the length direction of the frame 1. The upper template 40 and the lower template 41 are both provided with through holes penetrating their respective upper and lower surfaces. The through holes of the upper template 40 (defined as the first through holes 401) and the through holes of the lower template 41 (defined as the second through holes 410) are connected in a one-to-one correspondence. The engraving mold sleeve 42 corresponds to the through holes of the upper template 40 or the lower template 41 one-to-one. The engraving mold sleeve 42 is penetrated through the through holes of the upper template 40 and the lower template 41. The engraved mold sleeve 42 is composed of two half mold sleeves 420, one half mold sleeve 420 is connected and fixed to the inner wall of the through hole of the upper mold plate 40, and the other half mold sleeve 420 is connected and fixed to the inner wall of the through hole of the lower mold plate 41, so that the two half mold sleeves 420 can be closed along the length direction of the frame 1, and the above-mentioned engraved mold cavity 421 is formed when the two half mold sleeves 420 are closed. When the robot arm 60 drives each cake embryo adsorbed by each suction nozzle 619 to move to the top of the cake engraved mold 4, the two half mold sleeves 420 are in an open state; when each suction nozzle 619 pushes each cake embryo into each engraved mold sleeve 42 vertically, the upper mold plate 40 and the lower mold plate 41 are driven to move relative to each other along the length direction of the frame 1, so that the two half mold sleeves 420 of the engraved mold sleeve 42 are closed to form the engraved mold cavity 421. In this way, it can be avoided that each cake embryo enters each engraved mold cavity 421 to produce too much scraps and avoid waste of materials.

[0064] In one embodiment, the upper template 40 and the lower template 41 are automatically moved relative to each other along the length direction of the frame 1. Figure 2 and Figure 4 A fixing plate 44 is fixed above the frame 1, and the lower template 41 is fixed to the frame 1 through the fixing plate 44. A plurality of avoidance holes 440 are provided on the fixing plate 44. The plurality of avoidance holes 440 are in correspondence with the plurality of engraved mold sleeves 42. Each avoidance hole 440 is used to avoid each engraved mold sleeve 42, that is, each engraved mold sleeve 42 is slidably arranged in each avoidance hole 440. Among them, telescopic devices 43 are provided on both sides of the fixing plate 44 along the length direction of the frame 1. The telescopic devices 43 are selected from structures such as cylinders or electric push rods. The telescopic end of one telescopic device 43 is drivingly connected to the lower template 41, and the telescopic end of the other telescopic device 43 is drivingly connected to the upper template 40. It can be seen from this that when it is necessary to drive the upper template 40 and the lower template 41 to move relative to each other along the length direction of the frame 1 so that the two half mold sleeves 420 of the engraving mold sleeve 42 are opened, the telescopic ends of the two telescopic devices 43 move back to back along the length direction of the frame 1; when it is necessary to drive the upper template 40 and the lower template 41 to move relative to each other along the length direction of the frame 1 so that the two half mold sleeves 420 of the engraving mold sleeve 42 are closed, the telescopic ends of the two telescopic devices 43 move toward each other along the length direction of the frame 1.

[0065] It should be noted that the cross section of the engraved mold cavity 421 is elliptical or circular, and the cross section refers to the plane parallel to the upper surface of the upper template 40, that is, it can be understood that the engraved cake embryo can be elliptical or circular, which is not limited here. Of course, when the cross section of the engraved mold cavity 421 is elliptical, the cross section of the forming punch 32, the forming mold cavity 614, the avoidance hole 440, and the embryo sleeve 50 in the width direction of the frame 1 is also elliptical; when the cross section of the engraved mold cavity 421 is circular, the cross section of the forming punch 32, the forming mold cavity 614, the avoidance hole 440, and the embryo sleeve 50 in the width direction of the frame 1 is also circular. In short, those skilled in the art can make reasonable changes according to the actual situation, and are not limited here.

[0066] In one embodiment, referring to Figure 1 , Figure 2 and Figure 4 - Figure 7 , the upper template 40 and the lower template 41 are provided with waist-shaped grooves 7 penetrating the upper and lower surfaces thereof on both sides along the width direction of the frame 1. The waist-shaped grooves 7 on the upper template 40 correspond to and communicate with the waist-shaped grooves 7 on the lower template 41. The waist-shaped grooves 7 extend along the length direction of the frame 1. The fixing plate 44 is fixed with a limiting column 70 penetrating the waist-shaped grooves 7. Of course, when the two half mold sleeves 420 of the engraving mold sleeve 42 are in a closed state, the limiting column 70 is located at the center of the waist-shaped groove 7. It can be seen that the length of the waist-shaped groove 7 limits the relative movement of the upper template 40 and the lower template 41. At the same time, the cooperation of the waist-shaped groove 7 and the limiting column 70 can play a guiding role, avoiding the deviation of the upper template 40 and the lower template 41 during the relative movement along the length direction of the frame 1, thereby affecting the engraving effect of the engraving mold cavity 421.

[0067] On the basis of the above structure, the cake embryo engraving machine of the present invention further comprises a residual material pushing device 9 arranged on the frame 1, and the residual material pushing device 9 is used to push out the residual material on the cake embryo mold plate 33. That is to say, it can be understood that when the lifting mechanism 34 drives each forming convex mold 32 to rise into each forming mold cavity 614 to punch and cut the whole cake embryo placed on the cake embryo mold plate 33 into multiple small cake embryo bodies, the cake embryo will produce residual material on the upper surface of the cake embryo mold plate 33; when the mechanical arm 60 drives each suction nozzle 619 to move each small cake embryo body to the top of the cake engraving mold 4, the residual material pushing device 9 pushes out the residual material remaining on the cake embryo mold plate 33.

[0068] Specifically, refer to Figure 1 , Figure 2 and Figure 3The residual material pushing device 9 includes a linear drive module 90 and a pushing plate 91. The linear drive module 90 is arranged on the frame 1. The linear drive module 90 extends along the width direction of the frame 1. The linear drive module 90 is located on one side of the cake mold plate 33. The linear drive module 90 is drivingly connected to the pushing plate 91, and is used to drive the pushing plate 91 to push the residual material on the cake mold plate 33. In addition, in order to be able to guide the residual material out of the frame 1, a material guide mechanism 8 is also arranged on the frame 1. The material guide mechanism 8 is located below the other side of the cake mold plate 33, and the residual material pushed out of the push plate 91 is guided out of the frame 1 by the material guide mechanism 8.

[0069] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
