Description

Technical Field

[0001] The present invention relates to the technical field of assembled building block packaging production, and more specifically, to a double-annular divided and parallel lane switching circular conveying and packaging production line for multiple pieces. Background Art

[0002] Building block toys are popular with consumers due to their high degree of combination flexibility, diverse molding effects, and intellectual development potential. Each building block toy requires a variety of small building block components of varying sizes and types, mixed in predetermined quantities before packaging. During the production process, the required small building block components must be individually sourced and precisely matched in size and quantity, then mixed and packaged using packaging equipment.

[0003] In the packaging production of building block toys, the traditional production method is to manually classify the small building block parts, select the corresponding parts, count them, and then put them into packaging bags for packaging. The traditional production method is not only inefficient, but also has a high error rate in manual ingredient counting, which directly affects the quality of the finished products. In addition, it requires a lot of manpower, resulting in a significant increase in production costs. Moreover, due to the slow production speed, it cannot be applied to large-scale order production.

[0004] In order to improve the production efficiency and reduce the production cost of building block toys, the current production method mainly adopts a mechanical counting and packaging production line composed of multiple counting machines, a separate conveyor and a single packaging machine. Although the current mechanical counting and packaging production line has improved the production efficiency and the quality of the products to a certain extent compared with the traditional manual production method, the existing mechanical technology packaging production still has many disadvantages:

[0005] During the production process, the existing mechanical counting and packaging production line can only produce one product at a time. When the product model needs to be adjusted or replaced, the entire production line needs to be shut down, the production parts need to be cleaned, and then re-debugged and set up before production can resume. The replacement process consumes a lot of time and manpower, and the product adaptability is too low to meet the production needs of large quantities and multiple models. In addition, when there is a problem with the conveying equipment or packaging equipment on the production line or the packaging film material needs to be replaced, the entire production line will be shut down, and production and processing cannot be carried out smoothly. In serious cases, it will also affect the delivery deadline of the order. Failure to supply in time will also cause serious economic losses to the company. Moreover, during the production and packaging process, manpower is still required to monitor and operate the equipment, which still makes it difficult to reduce production costs.

[0006] In view of the many problems existing in the production and processing of existing building block toys, there is an urgent need to develop a technical solution for a new building block toy production line that can not only further improve the counting and packaging production efficiency of building block toys, but also realize the simultaneous processing of multiple types of products and achieve non-stop production for material change and maintenance, and have a high degree of automation to meet the production and processing needs of building block toy companies.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] The present invention adopts a compact double-ring conveying structure design, which effectively reduces the space occupied by the production line. The floor area is only equivalent to the area of a traditional production line. Combined with the circulating lifting mechanism, a complete circulating material receiving and conveying production line is formed. The production energy consumption can be reduced by 45% compared with two independent production lines, further reducing the power loss of the production line and the required production personnel configuration, which can greatly reduce the production and processing costs of the enterprise.

[0031] The present invention adopts a double-ring divided and merged circulating lifting and conveying device, which realizes uninterrupted material receiving, feeding and unloading processing through a circulating conveying design. The conveying process does not require human intervention, realizing closed-loop rapid material receiving and feeding production, and combined with a divided and merged switching mechanism, it plays a role in quickly adjusting the allocation and access of the processing production line according to real-time processing needs. It can also respond quickly when the production line needs to be replaced or a failure occurs, merge the normal processing production line into production, and quickly free up the equipment that needs to be repaired for operators to debug, while maintaining the original production efficiency and ensuring that the delivery period is not affected, to achieve rapid repair and maintenance. After the equipment debugging of the production line is completed, the production line is switched immediately through the divided and merged switching mechanism, and the original double-ring production line processing mode is quickly restored, realizing the function of non-stopping due to failure.

[0032] The present invention adopts a newly designed dual-channel automatic counting and blanking device, which can accurately measure parts and quickly transport the whole material, screen the material and mix it. During the metering process, it can also accurately identify the miscellaneous materials accidentally mixed into the material during the production process and immediately remove the miscellaneous materials, and quickly separate them from the material, ensuring that the assembled building block toys leaving the factory will not have missing or wrong parts in their packaging. The removed miscellaneous materials can be collected centrally to effectively keep the processing and production environment clean.

[0033] The present invention cooperates with a double-ring feeding mechanism and a dual-channel automatic counting and blanking device to realize the mixed synchronous production of multiple product numbers, has diverse production modes, and is easy to switch. It can meet the rapid production, metering and packaging needs of different types of assembled toys, and at the same time can realize the function of changing materials without stopping the machine, effectively solving the problem of time waste in changing materials in the existing production process, and can realize the mixed production function of multiple product numbers, greatly enhancing the flexibility of enterprises in the production and processing of different types of products.

[0034] The present invention mainly solves the problem that the existing similar production lines on the market are prone to jamming and failures during the metering and conveying processing, which requires the entire production line to be shut down for maintenance. At the same time, it can more effectively improve the productivity per unit time and save production energy, thereby achieving the purpose of increasing efficiency, reducing emissions and protecting the environment. Compared with existing production lines, the present invention has the advantages of high production efficiency, low production cost and failure maintenance rate, wide range of applications, rapid part model matching, accurate and timely screening and picking of materials, convenient debugging and maintenance operations, small production line space occupation, automated production, and low production labor input costs.

The processing parameters are set by the operation control unit 32 of the receiving and packaging control device 3, completing the installation of the double-ring divided and merged switching circulating conveying and packaging production line.

[0069] Example 1:

[0070] In this embodiment, a double-ring split-lane switching circular conveying system is arranged to simultaneously produce products of the same article number.

[0071] During production, the dual-channel automatic counting and blanking device 2 is first set to feed and batch count according to production needs, and then the parts of corresponding models are placed in the storage part and placed under the particle lifting mechanism 21. The parts are lifted and sent to the dual-channel whole material feeding mechanism 23 by the particle lifting mechanism 21, and the first vibrating feeding part 25 and the second vibrating feeding part 26 of the dual-channel automatic counting and blanking device 2 are screened, fed and counted for the parts of corresponding models. According to the preset counting parameters, the parts of corresponding models are dropped into the receiving mechanism 6 that arrives at the receiving station below in sequence. After the blanking is completed, the stop motor 72 of the receiving stop mechanism 7 rotates, and the stop control connecting rod 77 on the stop rotating block 76 can slide in the sliding groove 75 to drive the stop rocker rod 73 to rotate, so that the stop part 74 disengages from the locking groove 64, allowing the first conveyor belt 41 and the second conveyor belt 44 to continue to drive the receiving mechanism 6 that has completed one receiving process to move to the dual-channel automatic counting and blanking device 2 for the next receiving process. On the other hand, after the positioning groove 64 of the receiving mechanism 6 contacts the stop portion 74, the dual-channel automatic counting and dropping device 2 drops the counted parts into the receiving mechanism 6. After completing the receiving process of the corresponding parts of the product, the double-annular feeding mechanism 4 sends the receiving mechanism 6 to the arc-shaped guide portion 48 through the first connecting roller 43 and the second connecting roller 46. The clamping portion of the induction stop and discharge control mechanism is clamped in the positioning groove 64 below the receiving mechanism 6, and the receiving mechanism 6 is temporarily stopped in the arc-shaped guide portion 48. When the sensor below the first connecting roller and the second connecting roller detects that the material receiving clamping part 8 moves to the preset material receiving position, the sensor controls the clamping part to open, and the first connecting roller 43 and the second connecting roller 46 rotate to drive the material receiving mechanism 6 to continue to transport forward. The material receiving mechanism 6 is squeezed through the elastic stop part and then connected to the material receiving clamping part 83. After the material receiving mechanism 6 passes through the elastic stop part, the elastic stop part resets, and at the same time, the feedback signal controls the clamping part to reset and close to clamp the next material receiving mechanism 6. When the material receiving mechanism 6 is installed in the material receiving clamping part 83, the clamping groove 86 of the material receiving clamping part 83 is clamped into the clamping groove 64 below the material receiving mechanism 6, and the material receiving mechanism 6 is smoothly sent from the material receiving circulation part 82 to the lifting part 81, until the material receiving clamping part 83 is sent to the material unloading station of the lifting part 81. The material receiving mechanism 6 tilts downward to pour all models of parts in the material receiving groove through the inner wall of the unloading baffle along the inverted cone-shaped unloading port to the corresponding material receiving and packaging control device 3 below. The parts fall from the material receiving port 31 into the vertical packaging machine for independent packaging processing, and are discharged and stored after completion.

[0072] The production mode of this embodiment has the highest productivity per unit time and is suitable for production scheduling and processing of large quantities of goods.

[0073] In this embodiment, when the parts fall from the feeding ports of the first vibration feeding part 25 and the second vibration feeding part 26 into the corresponding first storage and removal towers 27 and the second storage and removal towers 28, the induction counting part 29 counts and detects the parts at the same time. The induction counting part 29 detects and records the time from the falling parts entering the induction counting part 29 to leaving the induction counting part 29, and then quickly compares it with the effective time period of the falling of the processed parts that has been learned and recorded in advance.

[0074] When the inductive counting part 29 detects that the time elapsed from the falling parts entering the inductive counting part 29 to the leaving thereof is within the effective time period of the falling of the processed parts that has been learned and recorded in advance, the inductive counting part 29 will accumulate the number of fallen parts and add one until the number of parts stored in the first material storage and picking tower 27 and the second material storage and picking tower 28 meets the number of parts to be packaged, and the first material storage and picking tower 27 and the second material storage and picking tower 28 rotate to the blanking gear position to carry out part blanking.

[0075] When the inductive counting part 29 detects that the time elapsed from the falling part entering the inductive counting part 29 to the leaving thereof is greater than or less than the effective falling time period of the processing part that has been learned and recorded in advance, the inductive counting part 29 judges the part as a part that does not meet the processing requirements, and controls the first material storage and removal tower 27 and the second material storage and removal tower 28 to rotate to the removal gear position, so that the parts that do not meet the processing requirements are removed from the removal outlet 20, and then quickly controls the first material storage and removal tower 27 and the second material storage and removal tower 28 to reset and rotate to the storage gear position, and the inductive counting part 29 resets the accumulated count to zero and counts again.

[0076] Example 2:

[0077] When there are many orders received, and the product numbers required in the orders are different, and the types of parts required for the corresponding numbers are small and the batch size is small, a double-ring divided and switched circular conveying multi-granule packaging production line can be arranged to produce two products with different numbers at the same time.

[0078] During production, first, according to production needs, the feeding and batching counting settings are made for the dual-channel automatic counting and blanking device 2 that needs to be connected to the production line, and then the part models required for the two types of goods are respectively placed in the storage part of the dual-channel automatic counting and blanking device 2, and the dual-channel automatic counting and blanking device 2 for accessing and processing the first type of goods is set, and the counting and blanking parameters of the first vibration feeding part 25, the first whole material screening part 251 and the first storage and blanking tower 27 are set. The vibrating feeding part 26 and the second material storage and removal tower 28 are set to be inactive, and the part model of the first type of item number corresponding to the processing is dropped into the material receiving mechanism 6 transported in the first conveying part through the first material storage and removal tower 27 according to the processing requirements. After the part model required for the first type of item number is received, the material receiving mechanism 6 is sent to the corresponding connected circulating lifting mechanism 8 through the arc guide part 48 and the induction material stopping and discharging control mechanism, and then the parts of the first type of item number are poured into the material receiving and packaging control device 3 from the discharge port of the circulating lifting mechanism 8 for packaging and discharging.

[0079] At the same time, the dual-channel automatic counting and blanking device 2 for accessing and processing the second type of goods is set, and the second vibration feeding part 26, the second whole material screening part 261 and the counting and blanking parameters of the second storage and removal tower 28 are adjusted. The first vibration feeding part 25 of the dual-channel automatic counting and blanking device for accessing and processing keeps working and the first storage and removal tower 27 is set to counting and hitting the return gear. The first storage and removal tower 27 is used as the feeding part to feed the second vibration feeding part 26. The second vibration feeding part 26 is used to feed the second material. The feeding end of the dynamic feeding part 26 falls to the second material storage and removal tower 28, and the part model of the corresponding second item number is dropped into the material receiving mechanism 6 transported in the second conveying part according to the processing requirements through the second material storage and removal tower 28. After completing the reception of the part model required for the second item number, the material receiving mechanism 6 is sent to the corresponding connected circulating lifting mechanism 8 through the arc-shaped guide part 48 and the induction material stopping and discharging control mechanism, and then the parts of the second item number are poured into the material receiving and packaging control device 3 from the discharge port of the circulating lifting mechanism 8 for packaging and discharging.

[0080] In this embodiment, the first conveying part and the second conveying part are respectively used as two independent processing production lines, and two products with different article numbers are counted, fed and packaged for processing at the same time, so that two small batch component orders can be produced and processed at the same time, which can improve the production efficiency of the double-ring divided and parallel lane switching circular conveying counting and packaging production line of the present invention.

[0081] Example 3:

[0082] When the double-annular divided and parallel lane switching circular conveying and packaging production line of the present invention is applied to the case where two products with different product numbers need to be produced but the two product numbers contain multiple parts of the same model with only a few parts having different models.

[0083] First, according to the total number of parts styles of the models that need to be processed, set up and start the corresponding number of dual-channel automatic counting and blanking devices 2, and put the parts of the same model required for the two product numbers directly into the storage part of the front-end dual-channel automatic counting and blanking device 2, set the screening parameters of the dual-channel whole material feeding mechanism 23 and the picking parameters of the counting storage blanking and picking mechanism 24 of the dual-channel automatic counting and blanking device 2 for placing the parts of the same model, and then set the counting quantity on the induction counting part 29 of the first storage and picking tower 27 according to the number of model parts required for the first product number, and then set the counting quantity on the induction counting part 29 on the second storage and picking tower 28 according to the number of model parts required for the second product number.

[0084] Then, the parts of different models contained in the two article numbers are placed independently into the storage part of the rear-end dual-channel automatic counting and blanking device 2.

[0085] According to the different types of parts required for processing the first type of article number, the screening parameters of the dual-channel whole material feeding mechanism 23 and the picking parameters of the counting storage blanking and picking mechanism 24 of the dual-channel automatic counting and blanking device 2 corresponding to the different types of parts are set. The dual-channel automatic counting and blanking device 2 used to process the different types of parts required for the first type of article number only starts the first vibrating feeding part 25 and the first storage and picking tower 27, and sets the counting quantity on the induction counting part 29 of the first storage and picking tower 27 according to the number of types of parts required for the first type of article number.

[0086] According to the different types of parts required for processing the second type of article number, the screening parameters of the dual-channel whole-material feeding mechanism 23 and the picking parameters of the counting storage blanking and picking mechanism 24 of the dual-channel automatic counting and blanking device 2 corresponding to the different types of parts are set, and the second vibration feeding part 26 and the second storage and picking tower 28 of the dual-channel automatic counting and blanking device 2 used to process the different types of parts required for the second type of article number are started, and the first vibration feeding part 25 is started at the same time. The first storage and picking tower 27 does not participate in the processing and is adjusted to the return gear. The first vibration feeding part 25 serves as a feeding device for the second vibration feeding part 26, and then the counting quantity of the induction counting part 29 on the second storage and picking tower 28 is set according to the number of parts of the model required for the second type of article number.

[0087] After the production setup is completed, the double-ring divided and switched circular conveying and counting packaging production line of the present invention is started to carry out double-item counting, conveying and packaging processing. The part model and quantity required for the first item number are dropped into the material receiving mechanism 6 in the first conveying section through the set first vibrating feeding section 25 and the first material storage and removal tower 27. After the material is received, the parts required for the first item number are poured into the material receiving and packaging control device 3 through the circulating lifting mechanism 8 for packaging and discharging of the first item number product; at the same time, the part model and quantity required for the second item number are dropped into the material receiving mechanism 6 in the second conveying section through the set second vibrating feeding section 26 and the second material storage and removal tower 28. After the material is received, the parts required for the second item number are poured into the material receiving and packaging control device 3 through the circulating lifting mechanism 8 for packaging and discharging of the second item number product.

[0088] The first conveying part is used as a counting, conveying and packaging production line for the first type of goods, and the second conveying part is used as a counting, conveying and packaging production line. Through this embodiment, the functional application of mixed packaging of multiple goods can be realized. The operation is simple and the production efficiency of the double-ring divided and parallel lane switching circular conveying counting and packaging production line of the present invention can be maximized, bringing better economic benefits to the enterprise.

[0089] Example 4:

[0090] In this embodiment, when it is necessary to carry out replacement counting and packaging production of new product numbers, there is no need to stop the entire production line. When the production volume of any one channel of the connected dual-channel automatic counting and blanking device 2 can meet the supply demand of the original product number, the channel splitting and merging switching mechanism 5 can be started to control the material receiving mechanism 6 to enter only the processing and blanking channel, and at the same time stop the counting and blanking processing of the other channel. After the channel switching is completed, the counting and screening parameter setting of the zero model of the new product number is directly carried out on the dual-channel whole material feeding mechanism 23 and the counting storage blanking and picking mechanism 24 of the vacant dual-channel automatic counting and blanking device 2. After the blanking and picking mechanism 24 completes the learning of the counting and screening parameter settings for the zero model of the new article number and the remaining parts of the original article number product are used for processing, the unloading and clearing processing is started, and the dual-channel automatic counting and blanking device 2 used for processing the original article number parts is unloaded, and the counting storage, blanking and picking mechanism 24 is controlled to be moved to the return gear position, and the dual-channel whole material feeding mechanism 23 continues to move, and the remaining parts are poured back into the return hopper 22, and the unloading cylinder 91 contracts to control the unloading movable door 92 to open, driving the movable door curtain 93 to lift and separate from the particle lifting mechanism 21, and the particle lifting mechanism 21 rotates in the opposite direction, and quickly drops the remaining parts directly from the return gap back into the discharge part, completing the clearing processing of the part model of the original article number product.

[0091] While starting the unloading and clearing processing, the material receiving mechanism 6 that has completed the material unloading is switched back to dual-channel transportation through the channel dividing and merging switching mechanism 5, and the spare dual-channel automatic counting and blanking device 2 that has learned and set the new article number part model parameters is used to process the new article number parts and is directly put into operation and production, thereby completing the purpose of switching the processing of the new article number parts and realizing the application of the function of changing materials without stopping the machine.

[0092] The application of this embodiment can solve the problem that all production lines in the existing market must stop after the production of a product number is completed, clean up the remaining materials, and then replace the products with new product numbers. Only after completing the debugging can the new product number be produced. The process requires a lot of time for cleaning and debugging, which greatly reduces the impact of material replacement operations on the production efficiency of the enterprise.

[0093] Embodiment 5:

[0094] In this embodiment, when one of the receiving and packaging control devices 3 in the dual-ring split-and-merge switching circular conveying and packaging production line of the present invention needs to replace the packaging film or malfunctions, the control unit only needs to control the merging and splitting units to operate. The merging adjustment cylinder 56 is used to telescopically rotate and fix the merging guide plate 55 to the discharge end of the conveying section corresponding to the receiving and packaging control device 3 that needs to be operated, blocking the discharge end of the conveying section corresponding to the receiving and packaging control device 3 that needs to be operated, so that the receiving mechanism 6 on the conveying section corresponding to the receiving and packaging control device 3 that needs to be operated can be sent along the merging guide plate 55 through the circulating lifting mechanism 8 corresponding to the normally functioning receiving and packaging control device 3 to the receiving and packaging control device 3 for packaging. When the merging and switching is completed, the operator can then perform the corresponding operations on the receiving and packaging control device 3 that needs to replace the packaging film or perform maintenance.

[0095] When the material receiving mechanism 6 completes the material guiding process and returns to the double-ring feeding mechanism 4 along the arc-shaped guide part 48 through the material receiving circulation part 82, the lane regulating cylinder 53 is used to extend and retract the lane guide plate 52 to rotate back and forth in an orderly manner at the feeding ends of the first conveying part and the second conveying part according to the preset swing amplitude, so that the material receiving mechanism 6 can enter the first conveying part and the second conveying part under the guidance of the lane guide plate 52, and continue to carry out synchronous conveying and material receiving processing under the conveyance of the first conveying part and the second conveying part.

[0096] In this embodiment, when it is necessary to replace the packaging film or perform maintenance on one of the material receiving and packaging control devices 3 of the double-ring divided and parallel channel switching circular conveying and counting packaging production line of the present invention, there is no need to shut down the machine and keep the double-ring feeding mechanism 4 operating normally. The material receiving mechanism 6 can be quickly guided to the normally operating material receiving and packaging control device 3, ensuring that the normal transportation and packaging processing of the production line will not be affected, maintaining the production efficiency of the double-ring divided and parallel channel switching circular conveying and counting packaging production line of the present invention, and meeting the normal production needs of the enterprise.
