Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chocolate packaging, in particular to a packaging device for spherical chocolate and a method thereof. BACKGROUND

[0002] Chocolate is a solid or semi-solid food made from cocoa products, sugar, dairy products, food additives, etc. as auxiliary raw materials, through a specific process. It contains various amino acids, proteins, B vitamins, vitamin E, calcium, magnesium, phosphorus and other nutrients. Eating high-purity chocolate in moderation not only does not induce cardiovascular disease, but also reduces the risk of disease and provides quick energy to the human body, reducing anxiety. With the development of the leisure food industry, the market demand for spherical chocolate has been growing year by year due to its smooth appearance and rich taste. Its production scale is shifting from small and medium-sized workshops to large-scale factories, which puts higher demands on the efficiency, accuracy and product protection of the packaging process.

[0003] Currently, the packaging of spherical chocolate mainly relies on traditional mechanical packaging or semi-manual packaging methods, which have certain shortcomings in actual use. For example, the feeding channel and the material distribution components such as the scoop and the distribution disc of the traditional mechanical packaging equipment have fixed sizes. When different diameters of spherical chocolate need to be packaged, the distribution funnel, the conveying pipeline and even the entire distribution mechanism need to be disassembled and replaced, which takes a long time to change production. It cannot meet the demand for rapid change of multiple varieties. At the same time, traditional equipment relies on fixed volume distribution, such as pre-set scoop volume or manual counting. However, spherical chocolate is prone to rolling and stacking due to its smooth surface, which can cause large deviations in the number of single packaging and has certain limitations. SUMMARY

[0030] The lower end of the feeding pipe 2 is communicated with a distribution pipe 35, the lower end of the distribution pipe 35 is communicated with the middle part of the upper end of the fixed shell 41 of the sub-packaging assembly 4 The middle part of the machine tool 1 is provided with a conveying belt 11, the two sides of the middle part of the conveying belt 11 are provided with limiting plates 12, the middle part of the limiting plate 12 is connected with a sub-packaging container 13, one side of one end of the machine tool 1 is fixedly installed with a visual sensor 14, and the visual sensor 14 is located on one side of the lower end of the discharging pipe 51.

[0031] The side of the U-shaped support 15 is fixedly installed with a controller 16, the motor 46, the emitter 52 of the reflection type photoelectric sensor, the receiver 53 of the reflection type photoelectric sensor and the visual sensor 14 are electrically connected with the controller 16.

[0032] The specific working principle and use method of the application will be explained in detail as follows: before sub-packaging, pre-adjustment is carried out, the size of the variable diameter hole 34 can be adjusted according to the size of the spherical chocolate to be sub-packaged, so that the variable diameter hole 34 can only pass one spherical chocolate at a time, which can effectively control the falling speed and prevent stacking; when adjusting, the plurality of adjusting plates 33 connected with the adjusting rod 32 are opened and closed, so that the diameter of the variable diameter hole 34 formed by the end part of the adjusting plate 33 changes. The diameter of the finally adjusted variable diameter hole 34 needs to be slightly larger than the diameter of the spherical chocolate to be sub-packaged, so that the chocolate can smoothly pass through one by one, and multiple chocolates can also be prevented from falling and stacking at the same time. Meanwhile, the lower end of the guide ring 21 in the feeding pipe 2 is provided with an inclined groove, which can guide the subsequent chocolate feeding and further prevent the variable diameter hole 34 from being blocked at the entrance.

[0033] Subsequently, the rotating ring 48 can be replaced to match the distribution cavity. First, unscrew the screws 44 around the positioning plate 43 of the fixed shell 41 and the detachable plate 42, then take off the detachable plate 42 through the pull rod 45, expose the rotating ring 48 inside the fixed shell 41, the distribution groove 49 around the rotating ring 48 and the fixed shell 41 form a cavity to accommodate chocolate, the rotating ring 48 with the size of the distribution groove 49 matched with the variable diameter hole 34 needs to be replaced, to ensure that the single chocolate falling from the variable diameter hole 34 can fall into the groove accurately, and after installing the new rotating ring 48 through the embedded handle 482, the rotating ring 48 and the cross plate 47 at the output end of the motor 46 need to be accurately connected through the cross slot 481 to avoid rotation deviation, and the surface of each distribution groove 49 on the surface of each rotating ring 48 is pasted with a soft pad 50, which can buffer the impact force when subsequent chocolate is received, preventing chocolate surface damage or deformation. At this time, the pre-adjustment of the device is completed, and the subsequent distribution link can be entered.

[0034] When dispensing, the spherical chocolate to be dispensed is conveyed to the inlet of the feeding pipe 2 through a pipeline, and the chocolate moves downward under the action of its own gravity, first guided by the inclined circular groove of the guide ring 21 to avoid accumulation on the inner wall of the feeding pipe 2, and then successively passes through the through hole 28 connecting the fixed disc 25 and the central part of the rotating disc 26, the variable diameter hole 34 with a size adjusted, and finally falls vertically through the dispensing pipe 35. Only a single chocolate passes through the variable diameter hole 34 at a time, ensuring stable dispensing rhythm; the user starts the motor 46 through the controller 16, the output end of the motor 46 drives the cross plate 47 to rotate, the cross plate 47 drives the rotating ring 48 to rotate synchronously in the fixed shell 41 through the cross slot 481, and when a certain dispensing groove 49 rotates to the position directly below the dispensing pipe 35, a single chocolate falling from the dispensing pipe 35 falls accurately onto the soft pad 50 in the groove; the rotating ring 48 continues to rotate, bringing the groove containing the chocolate to the position directly above the discharge pipe 51, and the chocolate falls from the groove into the discharge pipe 51 under the action of gravity, completing single quantitative conveying. The dispensing container 13 moves with the conveying belt 11 on the bed 1, and the visual sensor 14 installed on one side of the lower end of the discharge pipe 51 identifies the container position in real time. When the container is detected to move to the position directly below the discharge pipe 51, the visual sensor 14 sends a positioning signal to the controller 16, and the controller 16 immediately instructs the conveying belt 11 to stop running to avoid chocolate spilling due to container deviation; the visual sensor 14 adopts the working principle of the patent No. CN202410018085.X, which can effectively identify the position of the container. During the falling process of the chocolate from the discharge pipe 51, the light rays between the emitter 52 and the receiver of the symmetrically installed opposite type photoelectric sensor on both sides of the lower end of the discharge pipe 51 are blocked, and the sensor sends a counting signal to the controller 16 once it is blocked. When the count reaches the preset single dispensing quantity, the controller 16 instructs the motor 46 to stop rotating, and the dispensing action is paused. The weight of the spherical chocolate in the same batch is basically consistent during large-scale production, so the same weight dispensing can be realized by counting. When a single container completes the dispensing of the preset number of chocolates, the controller 16 instructs the conveying belt 11 to restart, conveying the container filled with chocolates to the next process, while the empty dispensing container 13 moves to the position directly below the discharge pipe 51 with the conveying belt 11, and is positioned again through the visual sensor 14. The conveying belt 11 stops, the motor 46 restarts dispensing, and enters the next round of dispensing cycle.

[0035] Throughout the entire workflow, the controller 16 acts as the core hub, receiving positioning signals from the vision sensor 14 and counting signals from the through-beam photoelectric sensor. It synchronously outputs commands to control the motor 46 to drive the rotating ring 48 to rotate or stop, and to start and stop the conveyor belt 11, achieving closed-loop control of container positioning, material dispensing initiation, counting completion, material dispensing stoppage, and conveyor belt 11 continuation. This process can be implemented through programming, the core being the input / output logic programming of the controller 16, establishing linkage rules between sensor signals and the actions of the actuators to achieve automated closed-loop control. Simultaneously, the size adaptation of the variable diameter hole 34 and the rotating ring 48, along with the anti-breakage design of the soft pad 50, ensures both the versatility, accuracy, and product integrity of the dispensing process.

[0036] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

During the process of the chocolate falling from the feeding pipe (51), it will block the light between the transmitter (52) and receiver of the through-beam photoelectric sensor symmetrically installed on both sides of the lower end of the feeding pipe (51). Each time the sensor is blocked, it sends a counting signal to the controller (16). When the count reaches the preset single dispensing quantity, the controller (16) instructs the motor (46) to stop rotating and the dispensing action is paused. The spherical chocolates of the same batch are basically the same in weight and size during the large-scale production process, so the same weight can be dispensed by counting. S4. When a single container has completed the pre-set number of chocolates, the controller (16) instructs the conveyor belt (11) to restart and transport the container full of chocolates to the next process. At the same time, the empty dispensing container (13) moves with the conveyor belt (11) to the bottom of the feeding pipe (51). The position is detected again by the vision sensor (14). The conveyor belt (11) stops, the motor (46) restarts dispensing, and the next round of dispensing cycle begins.
