Description

Technical Field

[0001] The invention relates to the technical field of soft candy production, and in particular to a soft candy automatic packaging machine and a packaging method based on gravity detection monomer feeding. Background Art

[0002] Soft candy is a soft and slightly elastic candy, usually transparent or translucent. It has a high water content, generally between 10% and 20%, which gives the soft candy a unique chewing taste. According to the different flavors, soft candy is mainly divided into fruit flavors (such as strawberry, orange, grape, etc.), milk flavors (such as milk, yogurt flavors) and refreshing flavors (such as mint, spearmint, etc.). In addition, the appearance of soft candy varies due to different molding processes. Common ones are regular rectangles or irregular shapes (such as animal shapes, geometric cuts, etc.) to meet different consumer needs.

[0003] In the traditional soft candy production process, weighing and filling usually rely on manual operation, that is, workers manually sort, weigh and pack into packaging bottles or bags. This method is not only inefficient, but also easily affected by human factors, resulting in large weight deviations, slow filling speeds, high labor costs and other problems. In addition, long-term manual work may also bring health risks, making it difficult to meet the high standards of modern food production.

[0004] Patent document announcement number CN116062216B discloses a soft candy weighing filling machine, which belongs to the field of soft candy production technology. Its technical points are: including a filling component, a reciprocating component and an adjusting component. When filling the soft candy, the soft candy is introduced into the feed barrel, and the filling bottle is placed on the transmission component. The adjusting component is turned on, and the adjusting component can drive the reciprocating component to slide back and forth through the connection with the reciprocating component. When the reciprocating component slides, the feed barrel can drive the support to rotate intermittently on the frame through the connection with the rotating component. When the discharge port at the bottom of the feed barrel rotates to connect with the discharge pipe on the surface of the fixed frame, the soft candy in the feed barrel can be discharged from the discharge pipe through the discharge port. The soft candy can enter the filling bottle on the surface of the transmission component, so that the soft candy can be filled in sequence.

[0005] The main function of the filling machine is to accurately weigh the soft candies in the filling bottle. However, in actual operation, when the weight of the soft candies in the filling bottle is lower than or higher than the standard value, a replenishment and return mechanism is required to adjust the soft candies. This process usually takes a certain amount of time to replenish or return the excess soft candies to ensure that the weight of each bottle of soft candies meets the predetermined standard. Since this replenishment and return process requires manual intervention or multiple steps of operation, the filling efficiency is relatively low, and there may be some operational uncertainties, which affects production efficiency and quality control. Summary of the invention

Subsequently, the material receiving trough accurately delivers the qualified soft candies to the packaging bottles on the conveyor line, and the automatic lidding mechanism completes the sealing, which effectively solves the problems of large weight deviation and low efficiency in the existing packaging.

DETAILED DESCRIPTION

[0021] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, the automatic soft candy packaging machine based on gravity detection monomer feeding includes a turntable 1 and a large-dose feeding mechanism 2 and a packaging bottle conveying mechanism 5 distributed in sequence along the circumference of the turntable 1, and also includes a weighing mechanism 3 and a small-dose compensation mechanism 4. The turntable 1 is provided with a material receiving trough 11 distributed along its circumference, and the bottom of the material receiving trough 11 is provided with an openable movable plate 12 and a weighing plate 13 located at the top of the movable plate 12 and capable of moving upward. When the weighing plate 13 moves to the weighing mechanism 3, it contacts with the weighing mechanism 3 and lifts the soft candy on the top thereof upward for weighing; if the weighing value does not reach the standard weight, the small-dose compensation mechanism 4 adds soft candy of the same weight as the weighing difference into the material receiving trough 11 according to the weighing difference to ensure that the standard weight is reached.

[0023] When the material receiving trough 11 moves to the top of the packaging bottle conveying mechanism 5, the bottom end of the material receiving trough 11 is opened; the packaging bottle conveying mechanism 5 is used to convey the packaging bottles to the bottom of the material receiving trough 11, and a cover mechanism 6 is also provided on the top of the packaging bottle conveying mechanism 5, and the cover mechanism 6 is used to cover the packaging cover on the top of the packaging bottle loaded with candy.

[0024] The large-dose feeding mechanism 2 includes a hopper and a valve arranged at the discharge port of the hopper, and the discharge port of the hopper is located at the top of the receiving trough 11.

[0025] The bottle conveying mechanism 5 includes a conveying platform 51, a positioning ring 52 and a rotating disk 53. The positioning ring 52 is provided with a first opening and a second opening. The rotating disk 53 is rotatably arranged on the conveying platform 51 and is coaxial with the positioning ring 52. An annular conveying channel is formed between the circumferential surface of the rotating disk 53 and the circumferential surface of the positioning ring 52. The width of the conveying channel is smaller than the diameter of the bottle. The circumferential surface of the rotating disk 53 is provided with arc-shaped grooves 531 distributed along its circumference. A first conveyor belt 54 is provided at the first opening. The first conveyor belt 54 is used to convey empty bottles to the conveying channel. A second conveyor belt 55 is provided at the second opening. The second conveyor belt 55 is used to send packaged bottles from the conveying channel.

[0026] The automatic soft candy packaging machine is mainly composed of a turntable 1, a large-dose feeding mechanism 2, a weighing mechanism 3, a small-dose compensation mechanism 4 and a packaging bottle conveying mechanism 5. The turntable 1 has multiple material receiving troughs 11 evenly distributed around the circumference, and a movable plate 12 that can be opened and closed and a weighing plate 13 that can be raised and lowered are provided at the bottom. When the material receiving trough 11 rotates to the weighing station, the weighing plate 13 rises and contacts with the weighing mechanism 3 to achieve accurate measurement of the soft candy; when it moves to the packaging station, the movable plate 12 automatically opens, allowing the soft candy of standard weight to fall into the packaging bottle below. The packaging bottle conveying mechanism 5 adopts a ring-shaped conveying design to ensure that the empty bottles are accurately positioned and connected to the materials, and the automatic capping is completed through the cover mechanism 6, realizing unmanned operation of the entire process.

[0027] The large-dose feeding mechanism 2 adopts a combination of a hopper and a controllable valve, and realizes rapid and rough feeding of soft candies by adjusting the valve opening to ensure that the initial weight is close to the standard value. The weighing mechanism 3 adopts a high-precision sensor to detect the quality of the soft candies in the receiving tank 11, and feeds back the data to the small-dose compensation mechanism 4. The small-dose compensation mechanism 4 performs micro-feeding according to the weighing difference, and finally controls the error of each soft candy within ±0.5g. In addition, the weighing plate 13 of the receiving tank 11 adopts a floating design, which not only avoids weighing interference, but also ensures the smooth transfer of soft candies.

[0028] The bottle conveying mechanism 5 is composed of a conveying platform 51, a positioning ring 52 and a rotating disk 53, wherein the rotating disk 53 is provided with an arc-shaped slot 531 in the circumference, and forms a circular conveying channel with the positioning ring 52. The empty bottle enters the channel from the first opening via the first conveyor belt 54, and passes through the filling station in sequence under the drive of the rotating disk 53; after the filling is completed, the finished bottle is sent out by the second conveyor belt 55 through the second opening. The cover mechanism 6 adopts a manipulator or a vacuum cover suction device, which automatically completes the capping or screwing after the bottle body is in place to ensure the sealing of the package. This design not only improves the conveying efficiency, but also avoids the problem of missing filling caused by the deviation of the bottle body, and is suitable for the production of packaging bottles of different specifications.

[0029] like Figure 4~Figure 5As shown, the bottom end of the weighing plate 13 is provided with a top column 131 extending downward, the top column 131 passes through the movable plate 12 and slides with it, the weighing mechanism 3 includes a pressure sensor 31, and the detection end of the pressure sensor 31 is arranged upward at the bottom of the turntable 1, when the bottom end of the top column 131 passes through the pressure sensor 31, the top column 131 slides upward and abuts against the detection end of the pressure sensor 31.

[0030] The bottom end of the weighing plate 13 is designed with a top column 131 extending downward, and the top column 131 is connected to the movable plate 12 and can slide smoothly with the movable plate 12 to ensure that the top column 131 can move stably and accurately during operation. The weighing mechanism 3 includes a pressure sensor 31, and the detection end of the sensor is installed at the bottom of the turntable 1 with the detection end facing upward. When the bottom end of the top column 131 passes through the pressure sensor 31, the top column 131 will slide upward and precisely contact the detection end of the pressure sensor 31. At this time, the sensor can sense the tiny pressure changes caused by the top column 131 in real time, and convert the pressure signal into electronic data to transmit to the control system.

[0031] At the same time, as the top column 131 slides upward, the weighing plate 13 will also synchronously lift the soft candies in the material receiving trough 11 upward. In this way, the pressure sensor 31 can not only accurately monitor the sliding pressure of the top column 131, but also accurately calculate the weight of the soft candies in the trough by contacting the soft candies in the material receiving trough 11. This data will be fed back to the system in real time and compared with the preset standard weight to make necessary compensation adjustments. If the weight of the soft candies is lower or higher than the standard value, the system will automatically add or remove excess soft candies by adjusting the feeding mechanism to ensure that the filling amount of each soft candy meets strict standards.

[0032] like Figure 5 , Figure 6 and Figure 7 As shown, the weighing mechanism 3 also includes an arc plate 32, which is arranged at the bottom of the turntable 1, the arc plate 32 is coaxial with the turntable 1, both ends of the arc plate 32 are chamfered and a groove 321 is arranged at its center position, and the pressure sensor 31 is arranged in the groove 321. When the bottom end of the top column 131 moves from the chamfer of the arc plate 32 to the top end of the pressure sensor 31, the top column 131 moves upward relative to the movable plate 12.

[0033] A ball or roller that can rotate relative to the top column 131 is disposed at the bottom end thereof, and a rolling fit can be formed between the top column 131 and the arc plate 32 , thereby reducing the friction between the top column 131 and the arc plate 32 .

[0034] The arc plate 32 is arranged at the bottom of the turntable 1 and is coaxially aligned with the turntable 1. Both ends of the arc plate 32 are chamfered to optimize the smoothness of the contact between the top column 131 and the pressure sensor 31, and reduce friction and wear. At the same time, a precise groove 321 is arranged at the center of the arc plate 32, which is specifically used to accommodate the pressure sensor 31.

[0035] The chamfer design of the arc plate 32 allows the top column 131 to smoothly contact the pressure sensor 31, and the pressure sensor 31 in the groove 321 can be firmly fixed to ensure the accuracy and stability of its position. When the bottom end of the top column 131 passes through the top of the pressure sensor 31 from the chamfer, it will move upward relative to the movable plate 12. During this process, the output signal of the pressure sensor 31 can reflect the weight change of the soft candy in real time. The system will compare this data with the standard weight and automatically adjust the compensation mechanism to ensure that the weight of each bottle of soft candy always meets the predetermined standard.

[0036] like Figure 6 As shown, the movable plate 12 is arranged at the bottom of the material receiving trough 11 in a radially sliding manner along the rotating plate. When the turntable 1 drives the movable plate 12 to move to the top of the packaging bottle conveying mechanism 5, the movable plate 12 drives the weighing plate 13 to move away from the bottom end of the material receiving trough 11 along the radial direction of the turntable 1.

[0037] As the weighing plate 13 moves radially along the turntable 1, the bottom of the material receiving trough 11 is effectively opened, providing sufficient space for the soft candies to fall. In this process, the synergistic effect of the movable plate 12 and the turntable 1 ensures the precise control of the weighing plate 13, avoiding overflow or deviation of the soft candies due to errors or improper movement. The action of opening the bottom of the material receiving trough 11 allows the soft candies to fall naturally and smoothly into the packaging bottles without hindrance, ensuring the efficiency and consistency of the filling process.

[0038] like Figure 6 As shown, a fixed ring 14 is provided at the bottom of the turntable 1, a notch 141 is provided on the circumferential surface of the fixed ring 14, and a guide column 121 is provided at the bottom end of the movable plate 12. The guide column 121 extends downward and abuts against the side surface of the fixed ring 14 along the radial direction of the turntable 1. When the guide column 121 slides from the outer circumferential surface of the fixed ring 14 to the notch 141, the movable plate 12 moves along the radial direction of the turntable 1 to move away from the bottom of the receiving trough 11.

[0039] The turntable 1 rotates in opposite directions to the rotating disk 53. When the movable plate 12 gradually moves away from the bottom of the material receiving trough 11, the bottom end of the material receiving trough 11 gradually forms a coaxial connection with the empty bottle so that the soft candies in the material receiving trough 11 can fall into the packaging bottle.

[0040] When the guide column 121 slides from the outer circumferential surface of the fixed ring 14 to the notch 141, the movable plate 12 moves along the radial direction of the turntable 1 and gradually moves away from the bottom of the receiving groove 11. This design not only ensures the smooth movement of the movable plate 12, but also stabilizes the entire weighing process through the combination of the guide column 121 and the fixed ring 14, avoiding deviations caused by external interference or equipment wear.

[0041] In addition, the turntable 1 and the rotating disk 53 rotate in opposite directions. This design can ensure that when the movable plate 12 gradually moves away from the bottom of the material receiving trough 11, the bottom end of the material receiving trough 11 gradually forms a coaxial docking with the empty bottle. This opposite rotational movement, combined with precise guidance and position adjustment of the movable plate 12, allows the soft candies to fall from the material receiving trough 11 into the packaging bottles more accurately. During this process, the bottom end of the material receiving trough 11 gradually docks with the empty bottle, avoiding possible overflow or blockage of the soft candies during the falling process, thereby ensuring that the amount of soft candies in each packaging bottle is accurate.

[0042] like Figure 8 , Fig. 9 and Fig.10 As shown, a connecting seat 15 is provided at the bottom end of the turntable 1 , and the connecting seat 15 is located on the side of the movable plate 12 facing the axis of the turntable 1 , and a tension spring 16 is provided between the connecting seat 15 and the movable plate 12 .

[0043] The tension spring 16 provided between the connecting seat 15 and the movable plate 12 plays a key role, so that the guide column 121 can always elastically abut against the side of the fixed ring 14, ensuring the stable movement of the movable plate 12. When the turntable 1 starts to rotate, the elastic effect of the tension spring 16 ensures that the guide column 121 of the movable plate 12 is always in the correct position, and can quickly slide to the notch 141 when passing through the notch 141 on the fixed ring 14. This design allows the movable plate 12 to move smoothly in the radial direction with minimal resistance, thereby quickly opening the bottom end of the receiving trough 11 and providing enough space for the filling of soft candies.

[0044] The tension spring 16 not only provides stable support for the movable plate 12, but also automatically adjusts the position of the movable plate 12 to ensure that it remains stable during the rotation of the turntable 1. Whenever the movable plate 12 and the guide column 121 of the fixed ring 14 slide to the notch 141, the elastic force of the tension spring 16 can ensure that the movable plate 12 moves quickly with appropriate speed and force, thereby achieving accurate opening of the bottom end of the receiving trough 11.

[0045] like Fig. 9 and Fig.10As shown, the material receiving trough 11 is provided with a material receiving cylinder 17 which is coaxially slidably matched therewith, a limiting ring 171 is provided at the top of the material receiving cylinder 17, and the diameter of the weighing plate 13 is larger than the outer diameter of the material receiving cylinder 17. When the weighing plate 13 moves out from the bottom end of the material receiving trough 11, the material receiving cylinder 17 moves downward in the material receiving trough 11.

[0046] When the movable plate 12 drives the weighing plate 13 to move radially along the turntable 1 to open the bottom end of the receiving trough 11, the receiving cylinder 17 in the receiving trough 11 can drop rapidly under the action of its own weight. Since the diameter of the weighing plate 13 is larger than the outer diameter of the receiving cylinder 17, the weighing plate 13 provides enough space for the receiving cylinder 17 when it moves out from the bottom end of the receiving trough 11, so that the receiving cylinder 17 can move downward. At this time, the limiting ring 171 abuts against the top edge of the receiving trough 11 to prevent the receiving cylinder 17 from moving further downward and control its position.

[0047] In order to make the soft candies fall smoothly and quickly, the rapid descent of the material receiving barrel 17 and the docking of the limiting ring 171 produce a certain vibration effect. The vibration effect can effectively prevent the soft candies from being retained or stuck in the material receiving barrel 17 by increasing the dynamic changes in the material receiving barrel 17. Due to the contact between the outer wall of the material receiving barrel 17 and the limiting ring 171, a certain mechanical impact will be generated, which can make the soft candies in the material receiving barrel 17 discharged more evenly and quickly.

[0048] like Fig.10 As shown, a slope 172 is provided on the side of the bottom end of the material receiving cylinder 17 facing the axis of the turntable 1. When the weighing plate 13 moves to the bottom of the material receiving trough 11, the edge of the weighing plate 13 slides from the slope 172 to the bottom end of the material receiving cylinder 17.

[0049] A fixing cylinder 18 is disposed in the material receiving groove 11 , and the material receiving cylinder 17 is slidably disposed in the fixing cylinder 18 and forms a spline fit therewith.

[0050] An opening is provided at the bottom end of the fixed cylinder 18 on one side facing the axis of the turntable 1 , and two rails 181 radially parallel to the turntable 1 are provided on both sides of the opening, and the movable plate 12 is slidably provided between the two rails.

[0051] When the movable plate 12 drives the weighing plate 13 to reset, the edge of the weighing plate 13 slides along the inclined surface 172 to the bottom end of the material receiving barrel 17. This design makes the movement path of the weighing plate 13 smoother and avoids hard collision or uneven contact. The inclined surface 172 is set to one side of the axis of the turntable 1, and the weighing plate 13 can easily contact the bottom end of the material receiving barrel 17 during the movement. This design ensures that the material receiving barrel 17 can be accurately lifted during each reset process to facilitate the next soft candy feeding.

[0052] A fixed cylinder 18 is provided in the receiving groove 11, and the receiving cylinder 17 is slidably provided in the fixed cylinder 18 and is precisely connected with the fixed cylinder 18 through spline matching. This spline connection ensures that the receiving cylinder 17 does not rotate relative to the fixed cylinder 18 during the resetting process, and ensures that the inclined surface 172 is on the moving path of the weighing plate 13, so as to facilitate the resetting of the receiving cylinder 17 and the weighing plate 13.

[0053] The method for automatically packaging soft candies based on gravity detection of monomer feeding is applied to an automatic soft candy packaging machine based on gravity detection of monomer feeding, and comprises the following steps: Step 1: Start the turntable 1, move one of the material receiving troughs 11 on the turntable 1 to below the large-dose feeding mechanism 2, and quickly put soft candies below the standard weight into the material receiving trough 11; Step 2: The material receiving trough 11 with the soft candies rotates to the top of the weighing mechanism 3, and the weighing mechanism 3 measures the soft candies in the trough; Step 3: The material receiving trough 11 continues to rotate to the bottom of the small-dose compensation mechanism 4, and the small-dose compensation mechanism 4 replenishes the material receiving trough 11 with the same weight of soft candies as the weighing difference according to the weighing difference to ensure that the standard weight is reached; Step 4: The material receiving trough 11 carrying the standard weight soft candies is moved to the top of the packaging bottle, and at the same time, the movable plate 12 slides to open the bottom of the material receiving trough 11, so that the soft candies fall into the bottle, and then the packaging bottle is capped by the upper cover mechanism 6.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
