[0022] In this embodiment of the invention, an automatic ingredient dispensing device and method for stir-frying are provided. Please refer to [link / reference]. Figures 1 to 17 As shown.
[0023] An automatic food dispensing device for stir-frying includes a frame 1, a clamping and conveying unit 2, a bag cutting unit 3, a bag opening unit 4, and a waste bag recycling unit 5.
[0024] The clamping and conveying unit 2 extends along the front and rear directions of the frame 1 to clamp and convey the connected food bags 6a, clamping both ends of the food bags 6a. The food bags 6a are connected in series by connecting strips 6b at least at one end of several food bags 6a. In this embodiment, the left and right ends of adjacent food bags 6a are connected in series by connecting strips 6b.
[0025] A clamping and conveying unit 2 is provided on both the left and right sides of the frame 1. The clamping and conveying unit 2 is used to clamp the opposite ends of the food bag 6a, and can drive the food bag to move along the front and back directions of the frame 1. Specifically, the clamping and conveying unit 2 on the left clamps the left end of the food bag 6a, and the clamping and conveying unit 2 on the right clamps the right end of the food bag 6a.
[0026] Specifically, the clamping and conveying unit 2 includes an upper clamping conveyor belt 2-1, a lower clamping conveyor belt 2-2, a tensioning roller 2-3, and a conveyor belt drive mechanism. The belt surfaces of the upper clamping conveyor belt 2-1 and the lower clamping conveyor belt 2-2 are used to clamp the food bag 6a. Furthermore, the tensioning roller 2-3 is mounted on the frame 1, contacting both the upper clamping conveyor belt 2-1 and the lower clamping conveyor belt 2-2, and tensioning the upper and lower clamping conveyor belts 2-1 and 2-2. This ensures that the upper and lower clamping conveyor belts 2-1 and 2-2 can firmly clamp the food bag 6a.
[0027] The conveyor belt drive mechanism includes a belt motor 2-4, a lower belt drive pulley 2-51, a lower belt driven pulley 2-52, an upper belt drive pulley 2-61, an upper belt driven pulley 2-62, and a transmission gear set 2-7. The lower belt drive pulley 2-51 is rotatably connected to the rear end of the frame 1, and the lower belt driven pulley 2-52 is rotatably connected to the front end of the frame 1. The lower clamping conveyor belt 2-2 is connected between the lower belt drive pulley 2-51 and the lower belt driven pulley 2-52. The upper belt drive pulley 2-61 is rotatably connected to the rear end of the frame 1, and the upper belt driven pulley 2-62 is rotatably connected to the front end of the frame 1. The upper clamping conveyor belt 2-1 is connected between the upper belt drive pulley 2-61 and the upper belt driven pulley 2-62. The output shaft of the belt motor 2-4 is connected to the input end of the transmission gear set 2-7, and the output end of the transmission gear set 2-7 is powered to the lower belt drive pulley 2-51 and the upper belt drive pulley 2-61.
[0028] The output shaft of the belt motor 2-4 rotates, which drives the lower belt drive wheel 2-51 and the upper belt drive wheel 2-61 to rotate synchronously via the transmission gear set 2-7, thereby driving the upper clamping conveyor belt 2-1 and the lower clamping conveyor belt 2-2 to run synchronously. During the synchronous operation of the upper clamping conveyor belt 2-1 and the lower clamping conveyor belt 2-2, the food bag 6a and the clamping conveyor belt do not undergo relative displacement.
[0029] Guide members 2-8 (first guide member and second guide member) are provided on both sides of the front end of the frame 1 in the horizontal and vertical directions. The inside of the guide member is a hollow cavity 2-81. The two ends of the guide member are connected and the inner side of the guide member has a slit 2-82. The end of the food bag 6a and the connecting strip 6b are embedded into the hollow cavity 2-81 from one end of the guide member. The connecting strip 6b cannot pass through the slit 2-82.
[0030] The frame 1 has a first guide member installed vertically on both sides of the front end, with the two ends of the first guide member being vertically positioned. The frame 1 also has a second guide member installed horizontally on both sides of the front end, with the two ends of the second guide member being horizontally positioned.
[0031] Lifting wheels 2-9 are rotatably connected to both sides of the front end of the frame 1. The lifting wheels 2-9 are located between the first guide member and the second guide member, and are driven to rotate by the output shaft of the belt motor 2-4. Specifically, the lower belt driven pulley 2-52 is connected to a first transition drive shaft, with a first transition pulley 2-91 at its end. The lifting wheel 2-9 is connected to a second transition drive shaft, with a second transition pulley 2-92 at its end. A transition drive belt 2-93 connects the first transition pulley 2-91 and the second transition pulley 2-92. The lower belt driven pulley 2-52 rotates to drive the lifting wheel 2-9 to rotate synchronously.
[0032] The food bag 6a and the connecting strip 6b can abut against the lifting wheel 2-9. As the lifting wheel 2-9 rotates, the food bag 6a and the connecting strip 6b are lifted upward.
[0033] An annular groove 2-90 is provided on the circumferential side of the lifting wheel 2-9, and the connecting strip 6b can be embedded in the groove 2-90 so that the groove 2-90 guides and limits the connected food bag 6a.
[0034] The outer diameter of the circumference of the lifting wheel 2-9 gradually decreases from the middle position to the inner end, so that when the food bag 6a comes into contact with the lifting wheel 2-9, the lifting wheel 2-9 exerts an inward force on the food bag 6a, preventing the food bag 6a from slipping off the frame 1.
[0035] The bag cutting unit 3 is set on the frame 1 and performs bag cutting operation on the food bags 6a conveyed by the clamping and conveying unit 2 one by one. The bag cutting operation is to cut open one end of the food bag 6a.
[0036] A support frame 3-1 is mounted on the machine frame 1. A blade shaft is connected to the center of the circular blade 3-2, and the blade shaft is rotatably connected to the support frame 3-1 via a bearing. A drive motor 3-3 is mounted on the support frame 3-1, and the output shaft of the drive motor 3-3 is connected to the blade shaft. When the output shaft of the drive motor 3-3 rotates, it drives the blade shaft to rotate, which in turn drives the circular blade 3-2 to rotate.
[0037] The output shaft of the drive motor 3-3 is connected to the drive pulley 3-41, and one end of the blade shaft is connected to the driven pulley 3-42. A transmission belt 3-43 connects the drive pulley 3-41 and the driven pulley 3-42. The output shaft of the drive motor 3-3 drives the drive pulley 3-41 to rotate, and the drive pulley 3-41 drives the driven pulley 3-42 to rotate via the transmission belt 3-43, which in turn drives the blade shaft to rotate.
[0038] A protective cover 3-11 is installed on the support frame 3-1, and the protective cover 3-11 is located above the circular blade 3-2. In this way, the protective cover 3-11 covers the circular blade 3-2, preventing operators from accidentally contacting the circular blade 3-2 and improving the safety of equipment operation.
[0039] The blade base 3-5 is mounted on the frame 1 and is located below the circular blade 3-2. The blade base 3-5 has a through-groove 3-51, in which the circular blade 3-2 can be partially embedded.
[0040] The front end of the blade base 3-5 is bent downward to form an inclined portion 3-52, so that the food bag 6a can be guided along the inclined portion 3-52 between the blade base 3-5 and the circular blade 3-2. The design of the inclined portion 3-52 at the front end of the blade base 3-5 effectively guides the food bag 6a smoothly into the cutting position, ensuring the accuracy of the cutting point and further improving the success rate of cutting and the precision of food dispensing.
[0041] The clamping and conveying unit 2 can move the food bag 6a toward the circular blade 3-2.
[0042] The swing mechanism drives the support frame 3-1 to swing relative to the frame 1, so that the circular blade 3-2 can be inserted into or disengaged from the blade groove 3-51. Specifically, the swing mechanism drives the support frame 3-1 to swing downwards to insert the circular blade 3-2 into the blade groove 3-51, and the swing mechanism drives the support frame 3-1 to swing upwards to disengage the circular blade 3-2 from the blade groove 3-51. When the bag cutting unit 3 is in the working state, the circular blade 3-2 is inserted into the blade groove 3-51; when the bag cutting unit 3 is not in the working state, the circular blade 3-2 is disengaged from the blade groove 3-51 to facilitate cleaning and replacement of the circular blade 3-2.
[0043] Specifically, the swing mechanism includes a support shaft 3-61, a swing arm 3-62, and a telescopic cylinder 3-63. A support base 1-1 is provided on each of the left and right sides of the frame 1. Both ends of the support shaft 3-61 are rotatably connected to the support base 1-1 on the same side via bearings. The support frame 3-1 is mounted on the support shaft 3-61, and one end of the swing arm 3-62 is connected to one end of the support shaft 3-61. One end of the telescopic cylinder 3-63 is hinged to the frame 1, and the other end of the telescopic cylinder 3-63 is hinged to the other end of the swing arm 3-62. The telescopic end of the telescopic cylinder 3-63 extends and retracts relative to the cylinder body end, thereby causing the swing arm 3-62 to swing, which in turn causes the support shaft 3-61 to rotate. The rotation of the support shaft 3-61 causes the support frame 3-1 to swing relative to the frame 1.
[0044] Photoelectric sensors 1-3 are installed at the feeding position of frame 1. Photoelectric sensors 1-3 are connected to the controller via signal cables. The food bag 6a is sprayed with an identification code. When photoelectric sensors 1-3 detect the identification code, they upload a signal to the controller, which then triggers the bag cutting unit 3 and the subsequent bag opening unit 4.
[0045] The bag-cutting unit 3 in this embodiment operates as follows: The swing mechanism drives the support frame 3-1 to swing downwards, causing the circular blade 3-2 to embed into the blade groove 3-51. The output shaft of the drive motor 3-3 rotates, driving the circular blade 3-2 to rotate. The clamping and conveying unit 2 clamps the opposite ends of the food bag 6a and moves the food bag 6a toward the circular blade 3-2. When the food bag 6a approaches the circular blade 3-2, the food bag 6a is guided by the inclined part 3-52 between the blade base 3-5 and the circular blade 3-2, and one end of the food bag 6a is cut off by the rotating circular blade 3-2, causing one end of the food bag 6a to tilt downwards. In the non-working state, the swing mechanism drives the support frame 3-1 to swing upwards, causing the circular blade 3-2 to disengage from the blade groove 3-51, facilitating the cleaning and replacement of the circular blade 3-2.
[0046] The bag opening unit 4 is set on the frame 1 and located behind the bag cutting unit 3. It opens the food bag 6a, which is conveyed by the clamping and conveying unit 2 and has one end cut open, to the opposite sides, and the food inside the food bag 6a falls and is put in.
[0047] The food bag opening device includes a first support arm 4-11, a first suction cup 4-21, a second support arm 4-12, a second suction cup 4-22, an action drive mechanism, and a vibration drive mechanism.
[0048] The first support arm 4-11 is located on one side of the frame 1, and the first suction cup 4-21 is located on the inner side of the first support arm 4-11. The inner side of the first support arm 4-11 is provided with two first suction cups 4-21 from top to bottom.
[0049] The second suction cup 4-22 is located on the inner side of the second support arm 4-12, wherein two second suction cups 4-22 are arranged from top to bottom on the inner side of the second support arm 4-12.
[0050] The motion drive mechanism is used to change the position of the first support arm 4-11 and / or the second support arm 4-12, so that the second suction cup 4-22 moves closer to or further away from the first suction cup 4-21. In this embodiment, the motion drive mechanism changes the position of the second support arm 4-12, so that the second suction cup 4-22 moves closer to or further away from the first suction cup 4-21.
[0051] The upper end of the second support arm 4-12 is hinged to the upper end of the first support arm 4-11. An actuation drive mechanism is used to swing the second support arm 4-12 relative to the first support arm 4-11, causing the second suction cup 4-22 to move closer to or further away from the first suction cup 4-21. Specifically, the second support arm 4-12 swings towards the first support arm 4-11 to bring the second suction cup 4-22 closer to the first suction cup 4-21; the second support arm 4-12 swings away from the first support arm 4-11 to move the second suction cup 4-22 away from the first suction cup 4-21.
[0052] The motion drive mechanism includes a first rotating shaft 4-31, a first motor 4-32, a first drive pulley 4-33, a first driven pulley 4-34, and a first synchronous belt 4-35. The upper end of the second support arm 4-12 is connected to the first rotating shaft 4-31, which is rotatably connected to the upper end of the first support arm 4-11. The axis of the first rotating shaft 4-31 coincides with the axis of the hinge. The output shaft of the first motor 4-32 is powered by the first rotating shaft 4-31. The first drive pulley 4-33 is connected to the output shaft of the first motor 4-32, the first driven pulley 4-34 is connected to the first rotating shaft 4-31, and the first synchronous belt 4-35 connects the first drive pulley 4-33 and the first driven pulley 4-34.
[0053] The output shaft of the first motor 4-32 rotates, causing the first drive pulley 4-33 to rotate by a set angle. The first drive pulley 4-33 drives the first passive pulley 4-34 to rotate by a set angle via the first synchronous belt 4-35, which in turn drives the first shaft 4-31 to rotate by a set angle, and finally causes the second support arm 4-12 to swing relative to the first support arm 4-11 by a set angle.
[0054] A support base 4-13 is provided at the upper end of the first support arm 4-11. Two limit switches 4-4 are provided on the support base 4-13 to monitor the relative positional changes between the first support arm 4-11 and the second support arm 4-12. The controller is connected to the limit switches 4-4 and the control terminal of the first motor 4-32 via signal cables.
[0055] A limit switch 4-4 is installed at one end of the support base 4-13. When the second support arm 4-12 swings toward the first support arm 4-11 to a set position, and the second suction cup 4-22 moves closer to the first suction cup 4-21 to a set position, so that the first suction cup 4-21 and the second suction cup 4-22 can abut against the food bag 6a, the limit switch 4-4 detects the second support arm 4-12. The limit switch 4-4 sends a signal to the controller, and the controller triggers the first motor 4-32 to stop rotating.
[0056] A limit switch 4-4 is installed at the other end of the support base 4-13. When the second support arm 4-12 swings away from the first support arm 4-11 to a set position, the second suction cup 4-22 moves away from the first suction cup 4-21 to a set position, causing the second suction cup 4-22 and the first suction cup 4-21 to open the food bag 6a, which has been cut open on one side by the bag-cutting unit 3, to the set maximum opening. The limit switch 4-4 detects the second support arm 4-12. The limit switch 4-4 sends a signal to the controller, and the controller triggers the first motor 4-32 to stop rotating.
[0057] When the second suction cup 4-22 approaches the first suction cup 4-21, the first suction cup 4-21 and the second suction cup 4-22 respectively adhere to the opposite sides of the food bag 6a. When the second suction cup 4-22 moves away from the first suction cup 4-21, the first suction cup 4-21 and the second suction cup 4-22 open up the food bag 6a, which has been cut open on one side, so that the food inside the food bag 6a falls into the automatic cooking machine under its own weight.
[0058] The shaking drive mechanism is used to drive the first support arm 4-11 and / or the second support arm 4-12 to shake. In this embodiment, the shaking drive mechanism drives the second support arm 4-12 to shake. In this way, as much food as possible in the food bag 6a is shaken into the automatic cooking machine, reducing the amount of food remaining in the bag.
[0059] The second support arm 4-12 includes a main arm 4-121 and a shaking arm 4-122. The middle position of the shaking arm 4-122 is hinged to the lower end of the main arm 4-121 via a hinge shaft 4-123. A second suction cup 4-22 is disposed on the inner side of the shaking arm 4-122. The shaking drive mechanism is used to drive the shaking arm 4-122 to swing relative to the main arm 4-121, so that the shaking arm 4-122 wobbles relative to the main arm 4-121.
[0060] The vibration drive mechanism includes a cam 4-51, a second motor 4-52, a return spring 4-53, a second drive pulley 4-54, a second driven pulley 4-55, a second rotating shaft 4-56, and a second synchronous belt 4-57.
[0061] A cam seat 4-124 is provided at the lower end of the main arm 4-121. The cam 4-51 is rotatably connected to the cam seat 4-124. The output shaft of the second motor 4-52 is powered to the cam 4-51. The cam 4-51 is set as a disc cam, and the edge of the cam 4-51 can abut against one end of the shaking arm 4-122.
[0062] A first connecting post 4-531 is provided at one end of the shaking arm 4-122, and a second connecting post 4-532 is provided on the cam seat 4-124. The two ends of the return spring 4-53 are respectively connected to the first connecting post 4-531 and the second connecting post 4-532.
[0063] The second drive pulley 4-54 is connected to the output shaft of the second motor 4-52, the second driven pulley 4-55 is connected to the cam 4-51 via the second shaft 4-56, and the second synchronous belt 4-57 is connected between the second drive pulley 4-54 and the second driven pulley 4-55.
[0064] The output shaft of the second motor 4-52 rotates, driving the second drive pulley 4-54 to rotate. The second drive pulley 4-54, via the second synchronous belt 4-57, drives the second driven pulley 4-55 to rotate. The second driven pulley 4-55, via the second shaft 4-56, drives the cam 4-51 to rotate. The cam 4-51 causes the shaking arm 4-122 to swing back and forth relative to the main arm 4-121, causing the shaking arm 4-122 to wobble relative to the main arm 4-121. Under the elastic force of the return spring 4-53, one end of the shaking arm 4-122 is kept in contact with the edge of the cam 4-51. The wobbling of the shaking arm 4-122 relative to the main arm 4-121 causes one side of the food bag 6a held by the second suction cup 4-22 to vibrate at a high frequency and with small amplitude, so as to shake off as much food as possible, especially the food attached to the inner wall of the bag, into the automatic cooking machine, reducing the amount of food residue in the bag.
[0065] The bag-opening unit in this embodiment operates as follows: The clamping and conveying unit 2 moves the food bag 6a along the frame 1 from front to back. At the cutting station, one end of the food bag 6a is cut open, while the other end remains clamped by the clamping and conveying unit 2. One end of the food bag 6a is tilted downwards, and the food bag 6a is positioned between the first support arm 4-11 and the second support arm 4-12. The first motor 4-32 drives the second support arm 4-12 to swing towards the first support arm 4-11, so that the second suction cup 4-22 approaches the first suction cup 4-21. When the second suction cup 4-22 approaches the first suction cup 4-21, the first suction cup 4-21 and the second suction cup 4-22 respectively adhere to the opposite sides of one end of the food bag 6a.
[0066] The first motor 4-32 drives the second support arm 4-12 to swing away from the first support arm 4-11, so that the second suction cup 4-22 moves away from the first suction cup 4-21. When the second suction cup 4-22 moves away from the first suction cup 4-21, the first suction cup 4-21 and the second suction cup 4-22 open the food bag 6a, which has been cut open at one end, so that the food inside the food bag 6a falls into the automatic cooking machine under its own weight.
[0067] The second motor 4-52 drives the shaking arm 4-122 to shake relative to the main arm 4-121, causing one side of the food bag 6a held by the second suction cup 4-22 to shake off as much food as possible from the food bag 6a into the automatic cooking machine, reducing the amount of food remaining in the bag.
[0068] A waste bag guide plate 1-2 is installed on the frame 1 and located behind the bag opening unit 4. The waste bag guide plate 1-2 extends from the uncut end of the food bag 6a to the cut end, and gradually curves upward from front to back. In this way, as the clamping and conveying unit 2 moves the food bag 6a along the frame 1 from front to back, the waste bag guide plate 1-2 lifts the empty food bag 6a so that it can easily enter the waste bag recycling unit 5.
[0069] The waste bag recycling unit 5 is mounted on the frame 1 and located behind the waste bag guide plate 1-2. It collects empty food bags 6a that are conveyed by the clamping and conveying unit 2. Specifically, the waste bag recycling unit 5 is equipped with a waste bag guide groove to transfer the empty food bags 6a, which are moved by the clamping and conveying unit 2 and lifted by the waste bag guide plate 1-2, to the waste bag storage container.
[0070] An automatic ingredient dispensing method for stir-frying, using the automatic ingredient dispensing device for stir-frying described in this embodiment, comprises the following steps: S1. The connected food bags 6a are clamped by the clamping and conveying unit 2 and conveyed along the front and rear directions of the frame 1.
[0071] Specifically, the output shaft of the belt motor 2-4 rotates, driving the lower belt drive wheel 2-51 and the upper belt drive wheel 2-61 to rotate synchronously via the transmission gear set 2-7, which in turn drives the upper clamping conveyor belt 2-1 and the lower clamping conveyor belt 2-2 to run synchronously. During the synchronous operation of the upper clamping conveyor belt 2-1 and the lower clamping conveyor belt 2-2, the upper clamping conveyor belt 2-1 and the lower clamping conveyor belt 2-2 clamp the opposite ends of the food bag 6a, driving the food bag 6a to move along the front and rear directions of the frame 1.
[0072] S2, the bag cutting unit 3 performs a bag cutting operation on each of the food bags 6a conveyed by the clamping and conveying unit 2. The bag cutting operation is to cut one end of the food bag 6a.
[0073] Specifically, the swing mechanism drives the support frame 3-1 to swing downwards, causing the circular blade 3-2 to embed into the blade groove 3-51. The output shaft of the drive motor 3-3 rotates, causing the circular blade 3-2 to rotate. The clamping and conveying unit 2 clamps the opposite ends of the food bag 6a and moves the food bag 6a toward the circular blade 3-2. When the food bag 6a approaches the circular blade 3-2, the food bag 6a is guided by the inclined part 3-52 between the blade base 3-5 and the circular blade 3-2, and one end of the food bag 6a is cut off by the rotating circular blade 3-2, causing one end of the food bag 6a to tilt downwards. In the non-working state, the swing mechanism drives the support frame 3-1 to swing upwards, causing the circular blade 3-2 to disengage from the blade groove 3-51, facilitating the cleaning and replacement of the circular blade 3-2.
[0074] S3, the bag opening unit 4 opens the food bag 6a, which is conveyed by the clamping and conveying unit 2 and has one end cut open, to the opposite sides, and the food inside the food bag 6a falls and is put in.
[0075] Specifically, the clamping and conveying unit 2 moves the food bag 6a along the frame 1 from front to back. At the cutting station, one end of the food bag 6a is cut open, while the other end remains clamped by the clamping and conveying unit 2. One end of the food bag 6a is tilted downwards, and the food bag 6a is positioned between the first support arm 4-11 and the second support arm 4-12. The first motor 4-32 drives the second support arm 4-12 to swing towards the first support arm 4-11, so that the second suction cup 4-22 approaches the first suction cup 4-21. When the second suction cup 4-22 approaches the first suction cup 4-21, the first suction cup 4-21 and the second suction cup 4-22 respectively adhere to the opposite sides of one end of the food bag 6a.
[0076] The first motor 4-32 drives the second support arm 4-12 to swing away from the first support arm 4-11, so that the second suction cup 4-22 moves away from the first suction cup 4-21. When the second suction cup 4-22 moves away from the first suction cup 4-21, the first suction cup 4-21 and the second suction cup 4-22 open the food bag 6a, which has been cut open at one end, so that the food inside the food bag 6a falls into the automatic cooking machine under its own weight.
[0077] The second motor 4-52 drives the shaking arm 4-122 to shake relative to the main arm 4-121, causing one side of the food bag 6a held by the second suction cup 4-22 to shake off as much food as possible from the food bag 6a into the automatic cooking machine, reducing the amount of food remaining in the bag.
[0078] S4, the waste bag recycling unit 5 recycles the empty food bag 6a that is conveyed by the clamping and conveying unit 2.
[0079] Specifically, as the clamping and conveying unit 2 moves the food bag 6a along the frame 1 from front to back, the empty food bag 6a is lifted by the waste bag guide plate 1-2 and transferred to the waste bag storage container by the waste bag recycling unit 5.
