Description

Technical Field

[0001] The present invention relates to the technical field of article packaging, and particularly relates to a packaging system and a packaging method for the production of granular beverages. Background Art

[0002] A granular beverage refers to a drink in which various fruit particles or other solid microparticles are added. During the production process of such beverages, generally, fruit juice, sugar solution, and other additives are mixed with fruit grains or microparticles, and then through processes such as blending, sterilization, and standing, a beverage with a rich taste and diverse nutrition is finally obtained.

[0003] The difference from conventional beverages is that during the packaging process of granular beverages, excessive shaking, impact, and vibration should be avoided as much as possible. In addition to possibly deforming and damaging the containers of granular beverages, it may also cause the fruit particles or other solid microparticles inside to collide and break with each other, affecting the overall appearance and taste of the beverage.

[0027] On the other hand, a packaging method for the production of granular beverages is provided, which is carried out based on the above-mentioned packaging system for the production of granular beverages, and includes the following steps:

[0028] S1: Arrange the beverage bottles after filling and capping in the first conveying mechanism;

[0029] S2: Place the packaging box for the packaged beverage in the second conveying mechanism;

[0030] S3: The packaging system operates independently, and during the process, the conveying speed of the beverage bottles in the packaging stage is regulated by the speed regulation unit;

[0031] S4: Extract the beverage bottles conveyed to the designated position into the packaging box through the extraction mechanism, and finally seal the packaging box.

[0032] The technical principle of the above solution is as follows:

[0033] In the packaging process of granular beverage production, it mainly involves the transportation and boxing of beverage bottles after filling. During this process, due to the different distances of beverage bottle transmission and the actual operating environment of the equipment, the intensity and duration of the impact vibration received by the beverage bottles are different. For the impact vibration with too high intensity or too long duration, it is easy to cause the beverage bottles to collide with each other and the particles inside the beverage bottles, resulting in the deformation of the beverage bottles or the premature fragmentation of some particles, which affects the overall appearance of the beverage and the taste when drinking. Since the impact vibration frequency received by the beverage bottles on the transmission equipment is usually high and it is difficult to accurately collect, but the change of the impact vibration will cause the particles inside to float. Therefore, the present invention adjusts the speed of the transmission equipment by observing the floating height of the particles in the beverage bottles, so as to avoid excessive or continuous impact vibration on the beverage bottles after filling. In addition, at the end of the beverage bottle transportation, a blocking mechanism is used to assist the beverage bottles to be pushed more smoothly to the stacking area, and then the extraction mechanism extracts the beverage bottles stacked stably into the packaging box to complete the packaging.

[0034] For the transportation of the packaging box, the cover part of the packaging box is restricted by setting a board hitting component and a board deflecting component, and the effectiveness of the board hitting and the effectiveness of the board deflecting are verified during the process to ensure that the cover part of the packaging box is effectively opened, avoid interfering with the beverage bottle packaging process, and ensure that the beverage bottles are stably loaded into the accurate position of the packaging box.

[0035] The above solution has the following beneficial effects:

[0036] 1. In the present invention, the impact vibration situation received by the beverage bottles is obtained based on the floating situation of the particles in the granular beverage bottles. At the same time, multiple transmission devices with independently adjustable speeds are used to transport the beverage bottles in the packaging process according to the impact vibration situation received by the beverage bottles, thereby reducing the impact vibration received in the beverage bottle packaging process. Since the impact vibration received during the transportation process of the beverage bottle packaging link may gradually accumulate or change suddenly after contacting other beverage bottles, compared with detecting the impact vibration received by the beverage bottles through sensors, it is more convenient to collect the floating situation of the particles in the beverage bottles by image, and it can truly reflect the impact of the impact vibration on the particles in the beverage bottles, which is convenient for more accurately protecting the beverage bottles from impact vibration.

[0037] 2. In the conveying stage of the packing box of the present invention, the cover part of the packing box is simultaneously opened, and the opening state is verified by the board hitting assembly and the board deflecting assembly. Compared with the traditional packing box conveying and opening technologies, on the one hand, it can open the cover part of the packing box while conveying, ensuring the efficiency of the packaging process. On the other hand, by verifying the effectiveness of the opening of the cover part of the packing box, it can avoid the impact on the beverage packaging caused by abnormal opening of the packing box cover.

[0038] 3. In the conveying stage of the packaging process of the present invention, the existing one conveying device is changed to multiple independently speed-adjustable conveying devices. Compared with the conveying by one conveying device, through the speed regulation between each conveying device, the impact vibration received by the beverage bottles can be effectively reduced. At the same time, since the beverage bottles in the packaging process usually adopt the grouped conveying method (the number of each group is 3×4, 4×6, etc.), the packaging system of the present invention can effectively reduce the mutual interference between each group of beverage bottles, further improving the stability of each group of beverage packaging processes.

[0039] 4. In the present invention, a horizontal laser emitter is used to monitor the suspension height of the particulate matter in the beverage bottle. Cooperating with the image sensor, the suspension height of the particulate matter can be more accurately collected to determine whether it exceeds the floating height of the particulate matter allowed in the beverage bottle. Moreover, the height of the horizontal laser emitter is adjustable to adapt to the monitoring requirements of the particulate beverage packaging process with different fluctuation allowable values.

[0040] 5. In the stacking process of the particulate beverage packaging of the present invention, a sliding baffle that can slide in two vertical directions is used to receive the beverage bottles being conveyed, so that the beverage bottles in the same group can stay more stably at the corresponding position of the stacking groove temporarily; and the temporarily staying beverages are pushed into the stacking groove to complete the stacking. During this process, the stability of the beverage bottles during the pushing process and the receiving process is monitored by the third pressure sensor and the fourth pressure sensor respectively, and then the pushing speed and the receiving speed are adjusted to improve the stability of the particulate beverage stacking process.

[0055] The following is a further detailed description through specific embodiments:

[0056] Embodiment 1: A packaging system for the production of granular beverages, as shown in combination with Figures 1-4 It includes a first conveying mechanism for conveying beverage bottles. The first conveying mechanism is composed of at least two first conveying devices 1 with adjustable conveying speeds, and the first conveying device 1 is signal-connected to a speed control unit. Specifically, in this embodiment, two first conveying devices 1 are used to form the first conveying mechanism (the user can select the number of first conveying devices 1 and the conveying length of a single first conveying device 1 according to needs. Preferably, it is ensured that there is only one group of beverage bottles being conveyed on one first conveying device 1 to avoid interfering with other normally conveyed beverage bottles). The first conveying device 1 adopts a conventional conveyor belt conveying device, and protective plates 2 for protecting the beverage bottles during conveyance are arranged on its left and right sides. The speed control of the conveyor belt conveying device is related to the driving member driving the conveyor belt. Therefore, in this embodiment, the driving member driving the conveyor belt is signal-connected to the speed control unit, so that the conveying speed of the first conveying device 1 can be adjusted through the speed control unit.

[0057] As shown in combination with Figure 5 and Figure 6As shown in the figure, it further includes a detection track 6 arranged along the conveying direction of the first conveying mechanism. An image acquisition mechanism is slidably connected to the detection track 6. In this embodiment, the detection track 6 is arranged on the protective plates 2 on both the left and right sides of the first conveying device 1, and it is necessary to ensure that the detection tracks 6 on adjacent first conveying devices 1 are accurately docked, so that the image acquisition mechanism can smoothly slide along the detection track 6 between the first conveying devices 1 to realize continuous real-time monitoring of the state of beverage bottles.

[0058] Specifically, the image acquisition mechanism includes a slider 4 slidably connected to the detection track 6. A rack 3 is arranged on the detection track 6 along its length direction. A first detection driving member (a stepping motor is used in this embodiment, not shown in the attached drawings) is arranged inside the slider 4. A gear (located inside the slider 4, not shown in the attached drawings) is coaxially and fixedly connected to the output shaft of the first detection driving member. The gear meshes with the rack 3. An image sensor 5 is arranged on one side of the slider 4 close to the first conveying mechanism. The first detection driving member and the image sensor 5 are in signal connection with the speed regulation unit.

[0059] In addition, several detection boxes 7 are fixedly connected to the side of the detection track 6. A horizontal laser emitter 10 is slidably connected inside the detection box 7. The horizontal laser emitter 10 is in signal connection with the main controller. A lead screw 9 for driving the horizontal laser emitter 10 to lift is arranged inside the detection box 7. A second detection driving member 8 (a stepping motor is used in this embodiment) for driving the lead screw 9 to operate is arranged on the detection box 7. Both the second detection driving member 8 and the horizontal laser emitter 10 are in signal connection with the speed regulation unit.

[0060] The floating height of the particles in the beverage bottle is jointly collected by the image sensor 5 and the horizontal laser emitter 10. The speed regulation unit is used to regulate the conveying speed of each first conveying device 1 based on the floating height of the particles in the beverage bottle. Specifically, the speed regulation unit is used to receive the preset fluctuation allowable value and the conveying speed value set by the user, estimate the allowable floating height of the particles in the beverage bottle based on the fluctuation allowable value. The image acquisition mechanism collects the floating height of the particles in the beverage bottle in real time, and compares the floating height of the particles in the beverage bottle collected in real time with the allowable floating height of the particles in the beverage bottle; when the floating height of the particles in the beverage bottle collected in real time is greater than or equal to the allowable floating height of the particles in the beverage bottle, the speed control unit controls each first conveying device 1 to execute a deceleration strategy; when the floating height of the particles in the beverage bottle collected in real time is less than the allowable floating height of the particles in the beverage bottle, the speed control unit controls each first conveying device 1 to execute an acceleration strategy until the conveying speed of the first conveying device 1 matches the preset conveying speed value. Among them, the allowable floating height of the particles in the beverage bottle is calibrated by the horizontal laser emitter 10. The second detection driving member 8 is controlled to operate through the main controller, so as to adjust the height of the horizontal laser line emitted by the horizontal laser emitter 10 on the beverage bottle body to adapt to the monitoring requirements of the packaging process of granular beverages with different fluctuation allowable values.

[0061] The deceleration strategy described above is to control the first conveyor device 1 where the beverage bottle is located to run at a uniform deceleration, estimate the conveying speed of the beverage bottle when it leaves the first conveyor device 1 based on the position of the beverage bottle when the uniform deceleration starts, and control the running speed of the next first conveyor device 1 to which the beverage bottle is about to be conveyed to match the conveying speed of the beverage bottle when it leaves the first conveyor device 1 where it is located. The acceleration strategy is to control the first conveyor device 1 where the beverage bottle is located to run at a uniform acceleration, and based on the position of the beverage bottle when the uniform acceleration starts, estimate whether the beverage bottle is on the same first conveyor device 1 when it accelerates to the preset conveying speed. When the beverage bottle is on the same first conveyor device 1 when it accelerates to the preset conveying speed, then control the running speed of the next first conveyor device 1 to which the beverage bottle is about to be conveyed to match the preset conveying speed; when the beverage bottle is not on the same first conveyor device 1 when it accelerates to the preset conveying speed, then control the running speed of the next first conveyor device 1 to which the beverage bottle is about to be conveyed to match the conveying speed of the beverage bottle when it leaves the first conveyor device 1 where it is located. Through the above deceleration strategy and acceleration strategy, it is possible to reduce the impact vibration on the granular beverage during the packaging process as much as possible on the premise of ensuring the packaging efficiency.

[0062] It further includes a second conveying mechanism for conveying the packing box. The second conveying mechanism includes a second conveying frame 11. A plurality of rollers 12 are rotatably connected to the middle of the second conveying frame 11. The rollers 12 are synchronously driven and connected (including ways such as using a synchronous belt, a chain 30, etc. to achieve synchronous drive connection). A roller driving member (preferably a reduction motor 29) is arranged at the bottom of the second conveying frame. The roller driving member is used to drive the rollers 12 to rotate synchronously. After the packing box is placed on the surface of the rollers 12, the automatic conveying of the packing box is realized through the synchronous rotation of the rollers 12.

[0063] In addition, a plurality of L-shaped guiding frames 13 are arranged on both sides of the second conveying frame 11. The L-shaped guiding frames 13 extend towards the middle of the second conveying frame 11, and a guiding shaft 14 is fixedly connected to a section of the L-shaped guiding frame 13 close to the middle of the second conveying frame 11. One end of the guiding shaft 14 facing the incoming direction of the packing box has an upward curvature. A plate hitting component is arranged at the front end of the guiding shaft 14. The plate hitting component includes plate hitting brackets 15 fixedly connected to both sides of the second conveying frame 11. A first rotary cylinder 16 is arranged on the plate hitting brackets 15. A plate hitting 17 is fixedly connected to the output shaft of the first rotary cylinder 16. The first rotary cylinder 16 is signal-connected to the main controller, and the roller driving member is signal-connected to the main controller. According to the preset conveying speed of the packing box, the main controller can control the first rotary cylinder 16 to run at a specified frequency. During the running process of the first rotary cylinder 16, the plate hitting 17 can reciprocate, so as to push aside the left and right side covers of the packing box, and then the opened covers are restricted by the guiding shaft 14, so as to keep the left and right side covers of the packing box in an open state.

[0064] The packaging frame 18 above the second conveying frame 11 is provided with a paddle assembly, which includes a paddle bracket 19 fixedly connected to the packaging frame 18, and a second rotary cylinder 20 is provided on the paddle bracket 19. A paddle rod 21 is fixedly connected to the output shaft of the second rotary cylinder 20, and a paddle roller 22 is fixedly connected to the end of the paddle rod 21 away from the output shaft of the second rotary cylinder 20. The second rotary cylinder 20 is connected to the main controller signal. Similarly, according to the preset conveying speed of the packaging box, the second rotary cylinder 20 can be controlled by the main controller to operate at a specified frequency. The operation of the second rotary cylinder 20 can enable the paddle roller 22 to pry open the cover plates on the front and rear sides of the packaging box, so that all the cover plates of the packaging box are fully opened at the specified packing position, which is convenient for the subsequent packaging and packing of beverages.

[0065] In order to verify the opening state of each cover plate of the packaging box, a plurality of first pressure sensors are fixedly connected to the bottom of the hitting plate 17, and the first pressure sensors are connected to the main controller by signal. The main controller is used to obtain the pressure signal collected in real time by the first pressure sensor during the operation of the first rotating cylinder 16, and judge whether the hitting plate 17 is successful based on the pressure signal collected in real time by the first pressure sensor; a plurality of second pressure sensors uniformly distributed circumferentially around the axis of the shifting roller 22 are fixedly connected to the outer wall of the shifting roller 22, and the second pressure sensor is connected to the main controller by signal. The main controller is used to obtain the pressure signal collected in real time by the second pressure sensor during the operation of the second rotating cylinder 20, and judge whether the shifting plate is successful based on the pressure signal collected in real time by the second pressure sensor. Since the hitting plate 17 and the shifting roller 22 are in contact with the first pressure sensor and the second pressure sensor respectively when the cover plate of the packaging box is opened, the opening state of the cover plate can be verified based on whether the first pressure sensor and the second pressure sensor collect pressure signals.

[0066] A packaging frame 18 is arranged between the first conveying mechanism and the second conveying mechanism, and an extracting mechanism is arranged on the packaging frame 18; a blocking mechanism is arranged on the packaging frame 18 above the end of the first conveying mechanism, and the blocking mechanism is used to limit the conveying position of the beverage bottle. Figure 7 As shown, the blocking mechanism includes a first cylinder mounting plate 40, a second cylinder mounting plate 39 and a stacking slot 35. In the initial state, the stacking slot 35 is located directly below the extraction mechanism. The stacking slot 35 is provided with an opening at one end close to the first conveying mechanism. The first cylinder mounting plate 40 is fixedly connected to the packaging frame 18 and faces the direction of the beverage bottles on the first conveying mechanism (i.e., the direction in which the beverage bottles are conveyed by the first conveying device 1). The second cylinder mounting plate 39 is fixedly connected to the packaging frame 18 and faces the stacking slot 35. In this embodiment, the first cylinder mounting plate 40 and the second cylinder mounting plate 39 are arranged at 90 degrees, facing different directions, respectively, to achieve the reception and pushing of beverage bottles.

[0067] A first cylinder mounting plate 40 is fixedly connected with a first cylinder 23. The output shaft of the first cylinder 23 is fixedly connected with a first baffle 25. A sliding baffle 32 is slidably connected to the first baffle 25. A locking assembly for restricting the sliding of the sliding baffle 32 is arranged between the first baffle 25 and the sliding baffle 32. A second cylinder mounting plate 39 is fixedly connected with a second cylinder 24. The output shaft of the second cylinder 24 is fixedly connected with a second baffle 26. One end of the sliding baffle 32 close to the second baffle 26 is slidably connected to the second baffle 26. A locking assembly for restricting the sliding of the sliding baffle 32 is also arranged between the second baffle 26 and the sliding baffle 32. The locking assembly is in signal connection with the main controller.

[0068] Specifically, since the sliding baffle 32 needs to be able to slide along the first baffle 25 and the second baffle 26, in this embodiment, the sliding baffle 32 is set as an L-shaped structure. One side of it remains slidably connected to the first baffle 25, and the other side is slidably connected to the second baffle 26. And to ensure that the sliding baffle 32 can stably slide into the palletizing groove 35 when the second cylinder 24 operates, a sliding groove 38 for the sliding baffle 32 to slide is opened on the side wall of the palletizing groove 35. As the second cylinder 24 operates, when the sliding baffle 32 disengages from the first baffle 25, the sliding baffle 32 can continuously slide stably along the sliding groove 38.

[0069] The locking assembly in this embodiment adopts a combined structure of an electromagnet and a magnet. The electromagnet is fixedly connected to the first baffle 25 and the second baffle 26, and the magnet is fixedly connected to both sides of the L-shaped sliding baffle 32. When the sliding baffle 32 slides to a certain position, the electromagnet is energized to attract the magnet, which can lock the sliding baffle 32 with the first baffle 25 or the second baffle 26. For example, when the first cylinder 23 operates, to ensure that the sliding baffle 32 can stably approach the beverage bottles along with the first baffle 25, when the electromagnet on the first baffle 25 corresponds to the magnet on the sliding baffle 32, the electromagnet on the first baffle 25 is energized to lock the sliding baffle 32 with the first baffle 25, so that the sliding baffle 32 can stably slide along the second baffle 26.

[0070] The extraction mechanism of this embodiment is used to extract the beverage bottles in the first conveying mechanism into the packing boxes on the second conveying mechanism to complete the packing process of the beverage with particles. For the extraction mechanism, the clamping extraction technology and the negative pressure extraction technology in the prior art can be adopted according to the material of the beverage bottles. This embodiment provides a specific structure of the extraction mechanism, combined with Figure 8As shown in the figure, it includes a main sliding plate 28 slidably connected to the packaging frame 18. A support block is fixedly connected to the main sliding plate 28. Chain wheels are rotatably connected to both the upper and lower ends of the support block, and a chain 30 is sleeved on the chain wheels. A reduction motor 29 is fixedly connected to the main sliding plate 28. The output shaft of the reduction motor 29 is coaxially and fixedly connected to the chain wheel at the lower end of the support block. An opening is formed in the main sliding plate 28. A connecting block 31 is slidably fitted in the opening formed in the main sliding plate 28. The connecting block 31 is hinged to the pin shaft of the chain 30. When the reduction motor 29 operates, it drives the chain 30 to rotate, so that the connecting block 31 slides along the opening formed in the main sliding plate 28. The connecting block 31 extends below the opening formed in the main sliding plate 28 and is fixedly connected to a pick-up plate (not shown in the drawings). A number of negative pressure suction cups are provided on the pick-up plate. The negative pressure suction cup is a conventional existing technology, which adsorbs the covered articles through the generated negative pressure. In this embodiment, the cap part of the granular beverage is adsorbed by the negative pressure suction cup, so as to realize the extraction of the granular beverage.

[0071] A third cylinder mounting plate 41 is fixedly connected to the packaging frame 18. A third cylinder 42 is fixedly connected to the third cylinder mounting plate 41. The output shaft of the third cylinder 42 is fixedly connected to the main sliding plate 28. The third cylinder 42 is signal-connected to the main controller. After the granular beverage bottle is successfully picked up, the operation of the third cylinder 42 is controlled by the main controller to push the main sliding plate 28 originally located above the stacking groove 35 to above the packaging box, and then the operation of the reduction motor 29 is controlled by the main controller to be able to load the granular beverage into the packaging box. By running in this way repeatedly, the beverage bottles in the first conveying mechanism are picked up and loaded into the packaging box on the second conveying mechanism to complete the loading of the granular beverage.

[0072] Combined with Figure 9 As shown in the figure, the packaging method based on the packaging system of this embodiment is as follows:

[0073] S1: Arrange the beverage bottles after filling and capping in the first conveying mechanism;

[0074] S2: Place the packaging box for packaging beverages in the second conveying mechanism;

[0075] S3: The packaging system operates independently, and during the process, the conveying speed of the beverage bottles in the packaging stage is regulated by the speed regulation unit;

[0076] S4: Extract the beverage bottles conveyed to the designated position into the packaging box through the extraction mechanism, and finally seal the packaging box.

[0077] Embodiment 2: The difference from Embodiment 1 is that the sliding baffle 32 is fixedly connected to a plurality of partitions 27, the partitions 27 extend along the length direction of the second cylinder mounting plate 39, a plurality of third pressure sensors 33 are fixedly connected to both sides of the partitions 27, and a plurality of fourth pressure sensors 34 are fixedly connected to the surface of the sliding baffle 32 away from the second cylinder 24; the third pressure sensors 33, the fourth pressure sensors 34 and the locking assembly are all connected to the main controller by signal. The main controller determines the acceptance of the beverage with particles based on the pressure signal detected by the fourth pressure sensor 34, ensures that a sufficient amount of beverage with particles is accepted between the predetermined partitions 27, and controls the contraction speed of the first cylinder 23 through the main controller during the acceptance process, so that the pressure signal detected by the fourth pressure sensor 34 during the entire acceptance process tends to be stable, ensuring that the beverage bottle with particles is stably accepted. Secondly, the main controller determines the stability of the process of pushing the beverage with particles to the stacking slot 35 based on the pressure signal detected by the third pressure sensor 33, and controls the extension speed of the second cylinder 24 through the main controller to make the pressure signal detected by the third pressure sensor 33 tend to be stable during the entire pushing process, thereby ensuring that the beverage bottle with particles is stably pushed to the stacking slot 35.

[0078] A fifth pressure sensor 36 is fixedly connected to the bottom surface of one end of the stacking slot 35 close to the first conveying mechanism, and a sixth pressure sensor 37 is fixedly connected to the bottom surface of one end of the stacking slot 35 away from the first conveying mechanism. Both the fifth pressure sensor 36 and the sixth pressure sensor 37 are connected to the main controller by signal, and the main controller is used to control the operation of the second cylinder 24 and the extraction mechanism according to the pressure signals detected by the fifth pressure sensor 36 and the sixth pressure sensor 37. Specifically, the pressure signal detected by the fifth pressure sensor 36 is used to determine whether the beverage with particles begins to be pushed into the stacking slot 35, and the pressure signal detected by the sixth pressure sensor 37 is used to determine whether the beverage with particles is pushed in place, and then the extraction mechanism is controlled to operate to complete the packing of the beverage with particles.

[0079] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
