[0002] Bread and cake are common pastries. The traditional production method is usually to bake a large piece and then cut it into several small pieces by hand. Since cake is loose and porous, has a high water content and a soft texture, it is very easy to cause local collapse and damage when the blade is cut and squeezed, and there is also a phenomenon of sticking to the knife.

[0003] With the development of technology, more and more food production equipment adopts production line cutting to improve the efficiency of cake production. For example, the patent with application number 201720723437.7 records an ultrasonic automatic longitudinal and transverse cutting food cutting production line. In the production line of this patent, the cake pieces are cut by fixing the longitudinal cutting combination knife and the transverse cutting combination knife on the conveyor. This cutting method has relatively large restrictions on the cutting shape of the cake.

[0031] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0032] As attached Figure 2 As shown, a multi-axis linkage ultrasonic cutting machine includes a conveyor 1, a gantry 13 fixed on the conveyor 1, and an ultrasonic cutter 21 located on the conveyor 1. The gantry 13 spans across both ends of the conveyor 1 in the width direction, and both ends of the gantry 13 are respectively fixed to the main beams 12 on both sides of the conveyor belt 11 of the conveyor 1.

[0033] Please refer to the attached Figure 6 As shown, the ultrasonic cutter 21 is fixedly connected to the ultrasonic transducer 22, and the ultrasonic transducer 22 is electrically connected to the ultrasonic generator (not shown in the figure). The ultrasonic generator can be fixed at the bottom of the conveyor 1. When working, the ultrasonic generator converts the mains electricity into a high-frequency and high-voltage alternating current and transmits it to the ultrasonic transducer 22. The ultrasonic transducer 22 outputs the amplitude to the ultrasonic cutter 21. The ultrasonic cutter 21 further amplifies the amplitude, focuses the ultrasonic wave and outputs the ultrasonic wave. The ultrasonic cutter 21 is used to concentrate the ultrasonic energy into the cutting part of the cake block 9, so that the ultrasonic generator drives the ultrasonic cutter 21 to achieve cutting. This method of ultrasonic cutting has a faster cutting speed, and the cutting process does not stick to the knife. At the same time, the cake block 9 can be easily cut without any pressure during cutting, which can avoid the occurrence of missing corners at the cutting position. It can be seen that the method of cutting the cake block 9 with the ultrasonic cutter 21 can improve the cutting efficiency of the cake block 9, and at the same time, the appearance of the cake after cutting and forming can be more complete.

[0034] As attached Figure 3 and 4 As shown, the front of the gantry 13 is connected to a transverse plate 31, and the front of the transverse plate 31 is connected to a lifting seat, and the ultrasonic transducer is connected to the lifting seat. Guide rails 35 are fixed to the upper and lower ends of the front of the gantry 13, and the length direction of the guide rails 35 is parallel to the width direction of the conveyor 1. Slide blocks 36 are fixed to the upper and lower ends of the back of the transverse plate 31, and the two slide blocks 36 are respectively adapted to be connected to the two guide rails 35 on the front of the gantry 13. Through this structure, the transverse plate 31 can only move horizontally along the width direction of the conveyor 1.

[0035] Continue to refer to the attached Figure 3 and 4, the gantry 13 is also connected to a rotating shaft 33 at one end along the width direction of the conveyor 1, and the connection of the rotating shaft 33 can be fixed to the upper and lower ends of the front of the gantry 13. The two ends of the rotating shaft 33 are respectively fixed to the two bearing seats, so as to limit the rotating shaft 33 to only rotate relative to the gantry 13. A transverse motor 32 is fixed to the other end of the gantry 13 along the width direction of the conveyor 1. Synchronous wheels are fixed to the transverse motor 32 and the rotating shaft 33, and the synchronous wheels of the transverse motor 32 and the rotating shaft 33 are simultaneously meshed and connected with a synchronous belt 34. The synchronous belt 34 is fixedly connected to the transverse plate 31, and the fixing method thereof can be to fix a pressure plate 37 on the transverse plate 31 by bolts, and press the pressure plate 37 against the synchronous belt 34, so that the synchronous belt 34 is fixed between the pressure plate 37 and the transverse plate 31 in a compressed manner. During operation, the transverse motor 32 drives the synchronous belt 34 to rotate, thereby pulling the transverse plate 34 to move along the width direction of the conveyor 1.

[0036] As attached Figures 3 to 5 As shown, vertical guide rails 45 are fixed on both sides of the front of the transverse plate 31, and sliders (not shown) are fixed on both sides of the back of the lifting seat 41, and the sliders on both sides of the lifting seat 41 are respectively adapted to be connected to the guide rails 45 on both sides of the transverse plate 31. Through this structure, the lifting seat 41 can only move vertically up and down relative to the transverse plate 31. A lifting motor 42 is fixedly connected to the top of the transverse plate 31, and the output shaft of the lifting motor 42 is fixedly connected to a screw rod 43, and the screw rod 43 is spirally connected to a nut support 44, and the nut support 44 is fixedly connected to the lifting seat 41. During operation, the lifting motor 42 drives the screw rod 43 to rotate, thereby driving the lifting and lowering of the lifting seat 41 relative to the conveying plane of the conveyor belt 11 by driving the nut support 44 to move vertically up and down. In addition, in combination with the attached Figure 1 and 2 As shown, the conveyor 1 is fixed with a protective cover 19, which surrounds the gantry 13 on all sides. The structure of the protective cover can prevent the cake pieces 9 being cut and processed from being contaminated by dust, and at the same time can protect the gantry 13 and the structure connected to the gantry 13.

[0037] Please refer to the attached Figures 3 to 5The lifting seat 41 is viewed from the side as an L-shaped bracket, specifically including a flat plate 411 parallel to the conveying plane of the conveyor belt 11 and a vertical plate 412 perpendicular to the conveying plane of the conveyor belt 11. A bearing seat (not shown) is fixed on the flat plate 411, and the ultrasonic transducer 22 passes through the bearing seat and is fixed. The fixed connection method can be achieved by assembling retaining springs at both ends of the ultrasonic transducer 22 located at the upper and lower ends of the bearing seat, and the ultrasonic cutter 21 is located below the flat plate 411. In addition, a rotating motor 23 is also fixed on the flat plate 411, and synchronous wheels are fixed on the output shaft of the rotating motor 23 and the ultrasonic transducer 22, and the synchronous wheels of the acoustic wave transducer 22 and the output shaft of the rotating motor 23 are simultaneously meshed and connected with a synchronous belt 24. When working, the rotating motor 23 drives the ultrasonic transducer 22 to rotate through the synchronous belt 24, thereby realizing the rotation of the ultrasonic cutter 21.

[0038] As attached Figure 6 and 13 As shown, the conveyor 1 is connected to the first transmission roller 15 and the second transmission roller 16 at both ends of the conveyor belt 11. Specifically, bearing seats 17 can be fixed under the main beams 12 on both sides of the conveyor 1. The first transmission roller 15 and the second transmission roller 16 are respectively fixedly connected to the bearing seats 17 of the main beams 12 on both sides, so that the first transmission roller 15 and the second transmission roller 16 can rotate, thereby driving the conveyor belt 11 to run, so as to realize the transportation and cutting of the first cake piece 9. Both ends of the conveyor 1 are connected to the drive motor 14, and the drive motor 14 is also equipped with a control system, which is a programmable PLC controller. A sensor 18 is also fixed on one side of the conveyor 1, and the sensor 18 can be a detection device such as a light sensor or an infrared sensor. The sensor 18 is fixed as shown in the attached Figure 6 The position close to the gantry 13 shown is used to sense the position of the cake piece 9, that is, when the sensor 18 senses the cake piece 9, the optical signal is converted into an electrical signal and output to the control system, and then the control system receives the signal and controls the drive motor 14 connected to the first transmission roller 15 to suspend operation or the drive motor 14 connected to the second transmission roller 16 to suspend operation. Specifically, the first transmission roller 15 is located at the front end of the conveying direction of the conveyor belt 11, and the second transmission roller 15 is located at the rear end of the conveying direction of the conveyor belt 11. The control system receives the signal from the sensor 18 to control the drive motor 14 connected to the first transmission roller 15 to suspend operation. This method is equivalent to positioning the cake piece 9 in the Y-axis coordinate direction. Further, the drive motor 14 can be controlled to resume operation after pausing for a specified time by writing a program, and the time is the time it takes to complete the cutting of a piece of cake 9.

[0039] As attached Figures 5 to 7As shown, the output shaft 141 of the driving motor 14 is fixed with a driving sleeve 7, and one end of the first transmission roller 15 and the second transmission roller 16 are both provided with a transmission sleeve 6, and the center of the transmission sleeve 6 is a through hole 62, and the through hole 62 is used to pass through the end of the first transmission roller 15 or the second transmission roller 16, and the inner wall of the through hole 62 is provided with a recessed guide groove 63, and at the same time, one end of the first transmission roller 15 and the second transmission roller 16 extends out of the bearing seat 17 and is fixed with a key bar 151, and the key bar 151 is embedded in the guide groove 63, and the size of the guide groove 63 is slightly larger than the size of the key bar 151. The transmission sleeve 6 can only slide relative to the axis of the first transmission roller 15 or the second transmission roller 16 through the restriction of the guide groove 63 and the key bar 151, and the first transmission roller 15 or the second transmission roller 16 can be restricted to rotate synchronously and in the same direction with the transmission sleeve 6 when rotating. Both ends of the conveyor 1 are also connected to a driving cylinder 8. When the control system controls the piston rod 81 of one of the driving cylinders 8 to extend, the piston rod 81 of the other driving cylinder 8 to retract. The specific control method is the control method of the cylinder by the pneumatic control system commonly used in the prior art, which will not be described in detail here. A chuck 82 is fixed at the end of the piston rod 81 of the driving cylinder 8, and the chuck 82 is provided with a slot 821. A card 64 is fixed on the transmission sleeve 6, and the card 64 is embedded in the slot 821 of the chuck 82. Preferably, the card 64 can be disc-shaped, so that it is always embedded in the slot 821 regardless of whether it is rotating or stopped, so that when the driving cylinder is working, the transmission sleeve 6 is driven to move relative to the first transmission roller 15 or the second transmission roller 16 by the telescopic movement of the driving piston rod 81.

[0040] As attached Figures 8 to 11 As shown, the end surface of the drive sleeve 7 is provided with a plurality of limit grooves 71 in an annular distribution, that is, the distribution of the array is arranged around the axis of the drive sleeve 7. Correspondingly, the annular surface of the transmission sleeve 6 is provided with a plurality of limit protrusions 61 in an annular distribution, that is, the distribution of the array is arranged around the axis of the transmission sleeve 6. Each of the limit protrusions 61 can be respectively embedded in the limit grooves 71. Furthermore, each of the limit protrusions 61 is inclined toward the middle on both sides facing one end of the drive sleeve 7, forming a plurality of limit protrusions 61 in an annular distribution, that is, the distribution of the array is arranged around the axis of the transmission sleeve 6. Fig. 9 The pointed angle structure shown in the figure, and both sides of the notch of the limiting groove 71 are also provided with inclined slopes 72, and the slopes 72 of two adjacent limiting grooves 71 are connected to each other to form a Figure 8 The pointed structure of the limiting protrusion 61 and the structure of the notch slope 72 of the limiting groove 71 can play a guiding role, so that no matter what angle the transmission sleeve 6 is rotated to, when it moves to the driving sleeve, each limiting protrusion 61 can be correspondingly embedded in each limiting groove 71, so that the driving motor 14 can drive the first transmission roller 15 or the second transmission roller 16 to rotate through the driving sleeve 7 and the transmission sleeve 6, thereby driving the conveyor belt 11 of the conveyor 1 to run.

[0041] Please refer to the attached Fig.10 and 11 , since when the piston rod 81 of one of the driving cylinders 8 extends, the piston rod 81 of the other driving cylinder 8 retracts, when the limiting protrusion 61 at the first transmission roller 15 is embedded in the limiting groove 71 of the driving sleeve 7, the limiting protrusion 61 at the second transmission roller 16 leaves the limiting groove 71 of the driving sleeve 7, or when the limiting protrusion 61 at the second transmission roller 16 is embedded in the limiting groove 71 of the driving sleeve 7, the limiting protrusion 61 at the first transmission roller 15 leaves the limiting groove 71 of the driving sleeve 7. This structure is equivalent to one of the driving motors 14 driving the transmission roller of the conveyor 1 to rotate, and the driving roller can be regarded as the driving roller driving the conveyor belt 11 to run, while the other transmission roller does not form a transmission connection with the driving motor 14 through the driving sleeve 7 and the transmission sleeve 6 at this time, and rotates driven by the running of the conveyor belt 11, so it can be regarded as a driven roller.

[0042] After adopting the above structure, the ultrasonic cutting machine of the present invention can be connected to a set of numerical control systems, which can be connected to a touch screen or a PC. The program is written into the numerical control system through the touch screen or the PC to control the ultrasonic cutter 21 to move in multiple axes according to the program. When working, the first transmission roller 15 is responsible for conveying the cake piece 9, and the second transmission roller 16 can be controlled by the numerical control system of the equipment to form the Y-axis moving coordinate in the numerical control system. When the numerical control system is working, the drive motor 14 connected to the second transmission roller 16 is controlled to rotate, so that the cake piece 9 on the conveyor belt 11 moves forward and backward relative to the ultrasonic cutter 21 along the running direction of the conveyor belt 11. Specifically, the CNC system is electrically connected to the transverse motor 32, the drive motor 14 connected to the second transmission roller 16, the lifting motor 42 and the rotating motor 23, so that the CNC system controls the lateral movement of the ultrasonic cutter 21 relative to the cake block 9 (equivalent to movement in the X-axis coordinate direction), drives the cake block 9 to move through the conveyor belt 11 (equivalent to movement in the Y-axis coordinate direction), drives the ultrasonic cutter 21 to move up and down through the lifting seat 41 (equivalent to movement in the Z-axis coordinate direction), and drives the ultrasonic cutter 21 to rotate on the lifting seat 41 through the rotating motor 23 (equivalent to rotation relative to the cake block 9). It can be seen that the structure of the present invention can perfectly match the CNC system to perform multi-axis linkage cake block 9 cutting work.

[0043] See attached Figure 1 , 2As shown in Figure 6, baffles 5 are fixed on both sides of the rear end of the conveying direction of the conveyor 1 (i.e., the end where the cake block 9 is placed in the conveyor belt 11), and the sides of the two baffles 5 have an inclined surface inclined toward the middle of the conveyor belt 11 and a plane parallel to the conveying direction, and the plane is located at the front end of the conveying direction relative to the inclined surface. When the cake block 9 is conveyed, the blocking of the baffles 5 on both sides can form a guiding effect, so that the cake block 9 moves closer to the middle of the conveyor belt 11 along the inclined surface of the baffles, so that when the cake block 9 is conveyed to the bottom of the gantry 13, it can be directly opposite to the middle position of the gantry 13, which is equivalent to the center point of the moving stroke of the transverse plate 31. This method is equivalent to positioning the X-axis coordinate direction of the cake block 9. In addition, the positioning of the Z-axis coordinate direction of the cake block 9 can be directly determined according to the thickness of the cake block 9. Specifically, the ultrasonic cutter 21 can be lowered until the tip touches the upper surface of the cake block 9, and then the Z-axis coordinate can be set to zero.

[0044] The working process of the present invention is as follows:

[0045] When the cake piece 9 is transported to the position of the gantry 13 on the conveyor 1, after the sensor 18 senses the cake piece 9, the control system controls the drive motor 14 connected to the first transmission roller 15 to stop running, and controls the piston rod 81 of the drive cylinder 8 to extend to drive the drive sleeve 6 to move away from the drive sleeve 7, so that the drive motor 14 and the first transmission roller 15 lose transmission; at the same time, the control system controls the piston rod 81 of the drive cylinder 8 located at the second transmission roller 16 to retract, so as to drive the drive sleeve 6 to move so that each limiting protrusion 61 is respectively embedded in each limiting groove 71 of the drive sleeve 7, so that the drive motor 14 and the second transmission roller 16 form a transmission connection.

[0046] After that, the control system sends a signal to the numerical control system to start the operation of the numerical control system, and controls the linkage of multiple axes of the ultrasonic cutter 21, and at the same time, the ultrasonic cutter 21 starts to move and cut relative to the cake block 9. When working, the numerical control system controls the traverse motor 32, the drive motor 14 connected to the second transmission roller 16, the lifting motor 42 and the rotating motor 23 according to the program to attach Figure 6 For example, when cutting a heart-shaped cake, the ultrasonic cutter 21 descends to insert into the cake piece 9, and the CNC system controls the transverse movement motor 32, the drive motor 14 connected to the second transmission roller 16, and the rotation motor 23 to operate to achieve cutting of the cake piece 9. After cutting a heart-shaped cake, the CNC system controls the lifting motor 42 to drive the ultrasonic cutter 21 to rise, and then controls the ultrasonic cutter 21 to move to the next cutting position through the transverse movement motor 32 and descend again for cutting, and repeats this process until the ultrasonic cutter 212 is reset after the cutting of a cake piece 9 is completed.

[0047] After the cake piece 9 is cut, the ultrasonic cutter 21 moves to the initial position, that is, above the middle of the conveyor 1, and the lateral movement motor 32, the lifting motor 42 and the rotating motor 23 as well as the drive motor 14 connected to the second transmission roller 16 are all suspended; at this time, the control system controls the piston rod 81 of the drive cylinder 8 located at the second transmission roller 16 to extend, so as to drive the drive shaft sleeve 6 to move away from the drive shaft sleeve 7, so that the drive motor 14 and the second transmission roller 16 lose transmission; at the same time, the piston rod 81 of the drive cylinder 8 located at the first transmission roller 15 is retracted, so as to drive the drive shaft sleeve 6 to move so that each limiting protrusion 61 is respectively embedded in each limiting groove 71 of the drive shaft sleeve 7, so that the drive motor 14 and the first transmission roller 15 form a transmission connection, so that the drive motor 14 can drive the conveyor belt 11 to run again through the first transmission roller 15, so as to realize the continued transportation of the cake piece 9, that is, the cake piece 9 that has been cut is output, and the cake piece 9 to be cut is transported toward the gantry 13.

[0048] During the above working process, the control system only receives the signal of the sensor 18 and controls the two driving cylinders 8 and the driving motor 14 connected to the first transmission roller 15. At the same time, the control system can also output signals to the numerical control system to make the numerical control system run. It can be seen that the control system is another set of control devices independent of the numerical control system. It can be seen that the finishing control mode of the present invention is the same as that of the existing numerical control machine tools, that is, the digital control of the geometric motion law of the tool (i.e., ultrasonic cutter 21) relative to the workpiece (i.e., cake block 9) is completed by NC (i.e., numerical control system), and the control of the machine tool auxiliary equipment is completed by PLC (i.e., control system).

[0049] In summary, the present invention drives the ultrasonic cutter 21 to move horizontally (equivalent to the axial movement of the X-axis) through the transverse plate 31, drives the cake block 9 to move longitudinally (equivalent to the axial movement of the Y-axis) through the conveyor belt 11, drives the ultrasonic cutter 21 to move up and down (equivalent to the axial movement of the Z-axis) through the lifting seat 41, and drives the ultrasonic cutter 21 to rotate on the lifting seat 41 through the rotating motor 23. It can be seen that the ultrasonic cutting machine of the present invention can make the ultrasonic cutter 21 relative to the cake block 9 to achieve multiple axial relative movements, so that it is convenient to use the CNC system to write a program to control the cutting machine, so that the ultrasonic cutter 21 can cut according to the path specified by the program, so that the ultrasonic cutting machine of the present invention can cut cakes of various shapes.

[0050] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
