Description

Technical Field

[0001] This utility model relates to the field of bulk food packaging, specifically to an automatic weighing and dispensing device for bulk food. Background Technology

[0002] With advancements in the food processing industry, an increasing number of individually packaged bulk foods are being sold in the market. Some packages contain multiple bulk foods (such as mushroom soup packets for easy soup making), while others contain only one bulk food (such as braised duck wings or necks, or pastries like sachima or small bread rolls). When packaging these bulk foods, they are often first individually packaged into small, independent units, and then weighed and repackaged into larger bags for sale.

[0003] Currently, when packaging bulk food into individual packages, operators typically weigh a certain number of individual packages. If the weight is within the standard weight range, the package is then packaged. However, due to the weight differences among the raw materials of the food, the weighing often does not conform to the standard weight range. In this case, operators need to replace or adjust one or more individual packages until the total weight meets the standard weight range before packaging. This process requires a lot of manpower and time, resulting in low packaging efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic weighing and dispensing device for bulk food, which can automatically weigh and dispense bulk food, thereby improving packaging efficiency.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] An automatic weighing and dispensing device for bulk food includes a control unit, a weighing unit, a dispensing unit, and a conveying unit connecting the weighing unit and the dispensing unit. The weighing unit includes a vibrating feeder, an electronic weighing device, a weighing pan, and a chute. A vibrating motor is installed at the lower end of the vibrating feeder, and a vibrating plate is installed at the upper end of the vibrating feeder. One end of the vibrating plate has a discharge port, which connects to the opening of the weighing pan. The weighing pan is rotatably mounted on the electronic weighing device. One end of the chute is a feeding port. The other end of the chute is the discharge port. The chute is inclined such that the inlet of the chute is higher than the outlet. The weighing pan is located above and to one side of the inlet of the chute. The conveying unit includes a conveyor belt and a conveyor motor for driving the conveyor belt. The conveyor belt has multiple hoppers arranged along the conveying direction. One end of the conveyor belt is connected to the outlet of the chute. A photoelectric sensor is installed on the conveyor belt corresponding to the outlet of the chute. The dispensing unit includes a dispensing funnel, a dispensing guide chute, a discharge hopper, and multiple accumulation pans. The conveyor belt... The other end is connected to the inlet of the dispensing funnel. One end of the dispensing guide groove is the inlet, and the other end is the outlet. The outlet of the dispensing funnel is connected to the inlet of the dispensing guide groove. Multiple accumulation trays are arranged on the same horizontal plane around the inlet of the discharge hopper, with each accumulation tray located below the dispensing funnel. The dispensing guide groove is inclined, and the outlet of the dispensing guide groove extends above the opening of the accumulation tray. The bottom of the dispensing guide groove is provided with a mechanism for driving the dispensing funnel. A first rotating servo motor that rotates horizontally in the guide groove; a first tilting servo motor that drives the opening of the corresponding accumulation plate to tilt downwards at the bottom of each accumulation plate; a rotatable output guide groove connected to the discharge port of the hopper; a recycling output groove and a dispensing output groove provided below the discharge port of the output guide groove; a control unit including a controller and a display connected to the controller; and the vibration motor, the electronic weighing device, the conveying motor, the photoelectric sensor, the first rotating servo motor, and the first tilting servo motor being respectively controlled and connected to the controller.

[0007] The weighing unit is mounted on the first frame, and the vibrating feeder is located above the weighing pan. The vibrating feeder is connected to the weighing pan through a weighing guide groove. One end of the weighing guide groove is the inlet, and the other end is the outlet. The weighing guide groove is inclined such that the inlet of the weighing guide groove is higher than the outlet of the weighing guide groove. The inlet of the weighing guide groove is located below the outlet of the vibrating pan, and the outlet of the weighing guide groove is located above the weighing pan.

[0008] The bottom of the weighing pan is provided with a second tilting servo for driving the open end of the weighing pan to tilt downwards, and the second tilting servo is connected to the controller.

[0009] The end of the conveyor belt that connects to the discharge port of the chute is the feed end, and the end of the conveyor belt that connects to the inlet of the dispensing funnel is the discharge end. The conveyor belt is inclined so that the discharge end is higher than the feed end. The conveyor belt is mounted on a conveyor belt support frame and has two opposite conveying surfaces. The two conveying surfaces are respectively provided with hoppers. The hoppers are right-angled triangular hoppers, and the right-angled surfaces of the hoppers are fixed to the corresponding conveying surfaces.

[0010] The dispensing funnel is installed on one end of the conveyor belt, and the side of the dispensing funnel near the conveyor belt has a notch for the hopper to pass through.

[0011] The accumulator is mounted on the second frame, which is provided with an L-shaped support rod for fixing the first rotating servo. The second frame is also provided with a recovery disc, which is on the same horizontal plane as each of the accumulators. The accumulators and the recovery disc are evenly arranged around the bottom of the dispensing guide groove.

[0012] The angle of a single rotation of the first rotating servo motor is consistent with the angle formed by the center symmetry lines of the two adjacent accumulation disks.

[0013] A second rotating servo motor for driving the output guide groove is installed at the bottom of the output guide groove. The second frame is provided with a mounting rod for mounting the second rotating servo motor at the position corresponding to the output guide groove. The second rotating servo motor is controlled and connected to the controller.

[0014] The controller is a controller with an MCU control unit.

[0015] With the above structure, this utility model provides an automatic weighing and dispensing device for bulk food. After powering on, the parameters are first set on the display, such as the total weight of the food to be dispensed, the minimum food weight, the number of hoppers, and the number of accumulation trays. Then, the bulk food is placed in the vibrating plate of the vibrating feeder, and the automatic weighing and dispensing operation is started.

[0016] Under the control of the controller, the vibratory feeder shakes the bulk food into the weighing pan of the electronic weighing device in sequence. The electronic weighing device weighs the food in the weighing pan. The electronic weighing device has a communication function. After the weighed food weight is read and saved by the controller, it controls the weighing pan to flip and output the weighed bulk food through the chute to the hopper of the conveyor belt. After the food has completely fallen into the hopper, the controller starts to control the conveyor motor to work at a timer. The conveyor belt moves forward to put the next empty hopper in place. While the conveyor belt is moving, the controller continues to control the weighing of the next bulk food. The end of the conveyor belt near the electronic weighing device is equipped with a photoelectric sensor. When the photoelectric sensor detects that the next empty hopper is in place, the controller controls the conveyor belt to stop and outputs the next food to the next hopper on the conveyor belt. This cycle repeats. The electronic weighing device weighs the food one by one and outputs it to the hopper of the conveyor belt in sequence. The controller records the order of the food weights.

[0017] The hoppers, fed sequentially by the conveyor belt, return from the other end of the belt, emptying the food into the dispensing funnel. The controller then controls the rotation of the dispensing guide chute, directing its outlet towards a specific accumulation tray. Bulk food is temporarily stored in this tray. When the accumulated food weight in a tray reaches a preset total weight, all food in that tray is output. Thus, food output from the conveyor belt and entering the dispensing guide chute flows into the accumulation tray along the direction of the guide chute. When the accumulated food weight in a tray meets the output requirements, the first tilting motor at the bottom of the tray, controlled by the controller, rotates, causing the corresponding tray to tilt and release the contents. Food is poured into the hopper. In this case, the output guide trough points to the dispensing output trough. The food falling into the hopper is output to the next packaging process along the output guide trough and the dispensing output trough. Food in a certain accumulation tray may not be matched and output for a long time, which will affect the overall dispensing efficiency. At this time, the controller can also control the accumulation tray to flip and the output guide to point to the recycling output trough, so that the food in the accumulation tray is output from the recycling output trough. After the recycled food output from the recycling output trough is temporarily stored in the material frame, it can be poured back into the vibrating plate of the vibrating feeder, or it can be directly sent back to the vibrating plate of the vibrating feeder using traditional industrial transmission equipment, re-weighed, and then enter the dispensing process.

[0018] Furthermore, when the food about to enter the dispensing funnel does not meet the weight requirement of any accumulation tray, the controller controls the dispensing guide chute to point towards the recovery tray and controls the output guide chute to point towards the recovery output chute. The food will then be output along the path consisting of the dispensing guide chute, recovery tray, dropping hopper, output guide chute, and recovery output chute.

[0019] Therefore, this utility model provides an automatic weighing and dispensing device for bulk food, which can automatically weigh and dispense bulk food, thereby improving packaging efficiency. Attached Figure Description

[0040] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0041] An automatic weighing and dispensing device for bulk food, such as Figures 1-4 As shown, it includes a control unit, a weighing unit, a dispensing unit, and a conveying unit connected between the weighing unit and the dispensing unit.

[0042] The weighing unit is mounted on the first frame 1. The weighing unit includes a vibrating feeder 21, an electronic weighing device 22, a weighing pan 23, and a chute 24. A vibrating motor is installed at the lower end of the vibrating feeder 21, and a vibrating plate 211 is installed at the upper end of the vibrating feeder 21. One end of the vibrating plate 211 extends to form a vibrating channel, and a discharge port is provided at the end of the vibrating channel. The vibrating feeder 21 is located above the weighing pan 23, which has an open upper end. The discharge port of the vibrating plate 211 is connected to... The weighing pan 23 is connected to the vibrating feeder 21 via a weighing guide groove 25. One end of the weighing guide groove 25 is the inlet, and the other end is the outlet. The weighing guide groove 25 is inclined so that the inlet is higher than the outlet. The inlet is below the outlet of the vibrating pan 211, and the outlet is above the weighing pan 23. In the weighing unit, after food is placed in the vibrating feeder 21, it passes through the vibrating channel and the weighing guide groove 25 into the weighing pan 23. Preferably, triangular baffles are provided on opposite sides of the weighing pan 23, and a square baffle connected to the two triangular baffles is provided at the end of the weighing pan 23 away from the weighing guide groove 25 to prevent food from falling out of the weighing pan 23.

[0043] The bottom of the weighing pan 23 is provided with a second tilting servo for driving the open part of the weighing pan 23 to tilt downward. The second tilting servo is fixed on the electronic weighing device 22. The drive arm of the second tilting servo is connected to the weighing pan 23, so that the weighing pan 23 can be tilted on the electronic weighing device 22.

[0044] One end of the chute 24 is the inlet, and the other end is the outlet. The chute 24 is inclined so that the inlet is higher than the outlet. The weighing pan 23 is located above the inlet of the chute 24. Overall, the vibrating plate 211, the weighing guide groove 25, the weighing pan 23, and the chute 24 are connected and fixed to the first frame 1 from top to bottom. When the opening of the weighing pan 23 is flipped downwards, the food in the weighing pan 23 can fall into the chute 24.

[0045] The conveying unit includes a conveyor belt 31 and a conveyor motor 32 for driving the conveyor belt 31. The conveyor belt 31 is mounted on a conveyor belt support frame 33 and has two oppositely arranged conveying surfaces. Multiple hoppers 34 are respectively arranged on the two conveying surfaces of the conveyor belt 31. The hoppers 34 are right-angled triangular hoppers, and the right-angled surfaces of the hoppers 34 are fixed to the corresponding conveying surfaces. The transmission method between the conveyor belt 31 and the conveyor motor 32 is a transmission method known in the art, such as using a belt drive 35.

[0046] The dispensing unit includes a dispensing funnel 41, a dispensing guide trough 42, a discharge hopper 43, and multiple accumulation trays 44. One end of the conveyor belt 31 is connected to the discharge port of the chute 24, and the end of the conveyor belt 31 connected to the discharge port of the chute 24 is the inlet end. A photoelectric sensor 36 is installed on one side of the conveyor belt 31 corresponding to the discharge port of the chute 24.

[0047] The other end of the conveyor belt 31 is connected to the inlet of the dispensing funnel 41. The end of the conveyor belt 31 connected to the inlet of the dispensing funnel 41 is the outlet end. The conveyor belt 31 is inclined so that its outlet end is higher than its inlet end. The dispensing funnel 41 is installed on one end of the conveyor belt 31, and a notch is opened on the side of the dispensing funnel 41 closest to the conveyor belt 31 for the material hopper 34 to pass through. The inclined conveying method occupies a small area and saves space.

[0048] One end of the dispensing guide channel 42 is the inlet, and the other end is the outlet. The outlet of the dispensing funnel 41 is connected to the inlet of the dispensing guide channel 42. In order to prevent food from falling, the inlet of the dispensing guide channel 42 is funnel-shaped.

[0049] Accumulating discs 44 are mounted on the second frame 5. The shape of the accumulating discs 44 is similar to that of the weighing disc 23. Multiple accumulating discs 44 are arranged around the feed inlet of the feed hopper 43 on the same horizontal plane of the second frame 5, with each accumulating disc 44 located below the dispensing funnel 41. The dispensing guide groove 42 is inclined, and its outlet extends above the opening of the accumulating disc 44. A first rotating servo motor 45 is mounted at the bottom of the dispensing guide groove 42 to drive its horizontal rotation. An L-shaped support rod 51 is mounted on the second frame 5 to fix the first rotating servo motor 45. The rotating shaft of the first rotating servo motor 45 is connected to the dispensing guide groove 42. The angle of a single rotation of the first rotating servo motor 45 coincides with the angle formed by the central symmetry lines of two adjacent accumulating discs 44, ensuring that each time the first rotating servo motor 45 operates, the outlet of the dispensing guide groove 42 points to the next accumulating disc 44.

[0050] Each accumulation disk 44 has a first tilting servo 46 at its bottom for driving the opening of the corresponding accumulation disk 44 to tilt downward. Each first tilting servo 46 is fixed on the second frame 5, and the drive arm of each first tilting servo 46 is connected to the corresponding accumulation disk 44.

[0051] The hopper 43 is fixed below the accumulation plate 44. A rotatable output guide groove 47 is connected to the outlet of the hopper 43. A second rotating servo motor 48 for driving the output guide groove 47 is installed at the bottom of the output guide groove 47. A mounting rod 52 for mounting the second rotating servo motor 48 is provided on the second frame 5 at the position corresponding to the output guide groove 47. The rotating shaft of the second rotating servo motor 48 is connected to the bottom of the output guide groove 47. An inclined recycling output groove 491 and a dispensing output groove 492 are connected below the outlet of the output guide groove 47.

[0052] The control unit includes a controller 61 and a display 62 connected to the controller 61. The controller 61 is a controller with an MCU control unit. For ease of operation, the control unit is also mounted on the first frame 1. The vibration motor, electronic weighing device 22, conveyor motor 32, photoelectric sensor 36, first rotation servo motor 45, first tilt servo motor 46, second rotation servo motor 48, and second tilt servo motor are respectively connected to the controller 61 for control.

[0053] In this utility model, the controller 61, vibrating feeder 21, electronic weigher 22, conveyor motor 32, photoelectric sensor 36, first rotating servo motor 45, first tilting servo motor 46, second rotating servo motor 48, and second tilting servo motor are all known components in the art.

[0054] This utility model discloses an automatic weighing and dispensing device for bulk food. After powering on, the parameters are first set on the display 62, such as the total weight of the food to be dispensed, the minimum food weight, the number of hoppers 34, and the number of accumulation trays 44. Then, the bulk food is placed in the vibrating plate 211 of the vibrating feeder 21, and the automatic weighing and dispensing operation is started.

[0055] Under the control of the controller 61, the vibratory feeder 211 sequentially shakes the bulk food into the weighing pan 23 of the electronic weigher 22. The electronic weigher 22 weighs the food in the weighing pan 23. The electronic weigher 22 has a communication function. After the weighed food weight is read and saved by the controller 61, it controls the second flipping servo motor at the bottom of the weighing pan 23 to flip the weighing pan 23, outputting the weighed bulk food through the chute 24 onto the hopper 34 of the conveyor belt 31. In practical applications, because the weighing process takes a little time, two to three electronic weighers 22 can be set up around the weighing guide chute 25, and the weighing guide chute 25 can be rotated to allow each electronic weigher 22 to weigh the product in turn, thereby improving weighing efficiency.

[0056] After the food has completely fallen into the hopper 34, the controller starts to control the conveyor motor 32 to work at a set time. The conveyor belt 31 moves forward to put the next empty hopper 34 into place. While the conveyor belt 31 is transmitting, the controller 61 continues to control the weighing of the next bulk food. When the weighing is completed and the conveyor belt 31 stops, that is, the next hopper 34 has been put into place, the next food is output to the next hopper 34 of the conveyor belt 31. This cycle repeats. The electronic weigher 22 weighs the food one by one and outputs it to the hopper 34 of the conveyor belt 31 in sequence. The controller 61 records the order of the food weights.

[0057] The conveyor belt 31 transports the weighed food in each hopper 34 forward in sequence. When the electronic weighing device 22 receives newly weighed food and it enters the empty hopper 34 at the end (feeding end) of the conveyor belt 31, the controller 61 controls the conveyor belt 31 to transport the hopper 34 forward. A photoelectric sensor 36 is installed at the end of the conveyor belt 31 closest to the electronic weighing device 22. When the photoelectric sensor 36 detects that the next empty hopper 34 is in place, the controller 61 controls the conveyor belt 31 to stop. This process is repeated, and new weighed food is continuously added to the hopper 34 at the end (feeding end) of the conveyor belt 31. Eventually, the weight of all the food in the hoppers 34 on the conveyor belt 31 is recorded in sequence in the memory of the controller 61 during the weighing process, forming a "selectable food sequence". Depending on the size of the food and other considerations in the actual application, the conveyor belt 31 can also use a ring or chain industrial conveyor, and the hoppers 34 can also be replaced by trays.

[0058] The hoppers 34, fed sequentially by the conveyor belt 31, return from the other end (discharge end) of the conveyor belt 31, emptying the food from the hoppers 34 into the dispensing funnel 41. The controller 61 then controls the dispensing guide trough 42 to rotate, directing its outlet towards a specific accumulation tray 44, temporarily storing the bulk food. When the accumulated food weight in a specific accumulation tray 44 reaches a preset total weight, all food in that tray will be discharged. Thus, food discharged from the conveyor belt 31 and entering the dispensing guide trough 42 will follow the direction of the guide trough 42 into the accumulation tray 44. When the accumulated food weight in a specific accumulation tray 44 meets the output requirements, the first tilting motor 46 at the bottom of the accumulation tray 44 operates under the control of the controller 61, causing the corresponding accumulation tray 44 to tilt and empty the food into the dropping hopper 43. In this case, the output guide trough 47 points towards the dispensing funnel 41. Food that falls into the hopper 43 after exiting the trough 492 is output along the output guide trough 47 and the dispensing output trough 492 to the next packaging process. Specifically, the controller 61 determines which accumulation tray 44 the food output from the conveyor belt 31 is matched with based on the weight of each accumulation tray 44, the weight of each food on the conveyor belt 31, and the preset total weight. Food in a certain accumulation tray 44 may not be matched for a long time, affecting the overall dispensing efficiency. In this case, the controller 61 can also control the accumulation tray 44 to flip and the output guide trough 47 to point to the recycling output trough 491, so that the food in the accumulation tray 44 is output from the recycling output trough 491. The recycled food output from the recycling output trough 491 is temporarily stored in the material frame and can be poured back into the vibrating plate 211 of the vibrating feeder 21, or it can be directly sent back to the vibrating plate 11 of the vibrating feeder 21 using traditional industrial transmission equipment, re-weighed, and then enter the dispensing process.

[0059] Furthermore, a recovery tray 7 is also provided on the second frame 5. The recovery tray 7 is on the same horizontal plane as each accumulation tray 44, and the accumulation trays 44 and the recovery tray 7 are evenly arranged around the top of the discharge hopper 43. When the food about to enter the dispensing funnel 41 does not meet the weight requirement of any accumulation tray 44, the controller 61 controls the dispensing guide trough 42 to point towards the recovery tray 7 and controls the output guide trough 47 to point towards the recovery output trough 491. The food will be output along the path of dispensing funnel 41, dispensing guide trough 42, recovery tray 7, discharge hopper 43, output guide trough 47 and recovery output trough 491.

[0060] This utility model discloses an automatic weighing and dispensing device for bulk food, which is suitable for weighing and dispensing bulk food of various sizes and densities, whether uniform or non-uniform. It has a high degree of automation, high efficiency, is easy to maintain, and has low cost.

[0061] The above embodiments and figures are not intended to limit the food form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
