Description

Technical Field

[0001] The present invention relates to the technical field of cigarette stacking of cigarette forming parts, and more specifically, to a single-channel to multi-station stacking system and method. Background Art

[0002] In the process of stacking finished cigarettes into warehouses, the finished product warehouses in the past mostly used conveyor lines to transport the pallets of palletized cigarettes. The conveyor line is like a continuous "conveyor belt" that can continuously transport the pallets along a predetermined route. In recent years, in order to reduce the number of conveying equipment in the finished product warehouse and make the on-site environment more concise and orderly, some cigarette factories have begun to explore new ways of warehouse handling, that is, using AGV (Automated Guided Vehicle) to replace traditional conveyor lines. AGV has many different forms, such as fork-type AGV, lurking AGV with shelves on the back, and lurking AGV with retractable fork arms. Among them, the lurking AGV with retractable fork arms has become a new development direction due to its small size, ability to complete the picking and placing of goods and handling work without any assistance, 360-degree rotation in place, and small operating channel. However, this type of lurking AGV has the disadvantage that the fork arm takes a long time to extend and retract when performing the picking and placing task.

[0003] In the finished product automatic storage area, whether the latent AGV can timely perform tasks such as taking away the palletized cigarette pieces and storing them, replenishing empty pallets at the palletizing station, and replenishing empty pallet groups at the palletizing station has become a key factor affecting the efficiency of the automatic storage of finished cigarette pieces. Especially in high-flow operation scenarios that require frequent pick-up and release of goods, this time delay will continue to accumulate, reducing the number of pallets that can be transported and stored in a unit time, slowing down the rhythm of the entire finished cigarette piece storage, and is not conducive to achieving efficient and fast storage operations. Summary of the invention

[0004] One object of the present invention is to provide a single-channel multi-station palletizing system and method to solve the problem that the fork arm has a long time to extend and retract when performing the task of picking and releasing goods, which slows down the rhythm of the entire finished product cigarette warehousing and is not conducive to achieving efficient and fast warehousing operations.

[0005] According to a first aspect of the present invention, a single-channel to multi-station palletizing system is provided, characterized in that it comprises:

[0006] Two palletizing robots, palletizing robot No. 1 and palletizing robot No. 2;

[0007] Conveying and caching channels: three conditioned smoke conveying and caching channels are respectively configured for the No. 1 palletizing robot and the No. 2 palletizing robot, and one conditioned smoke reflux channel is additionally configured for the No. 1 palletizing robot;

[0008] Multiple palletizing stations: the No. 1 palletizing robot corresponds to 4 palletizing stations, which are respectively set as A1, A2, B1, and C1. The 4 palletizing stations A1, A2, B1, and C1 are spaced around the No. 1 palletizing robot; the No. 2 palletizing robot corresponds to 4 palletizing stations, which are respectively set as A3, B2, B3, and C2. The 4 palletizing stations A3, B2, B3, and C2 are spaced around the No. 2 palletizing robot.

[0009] Optionally, the three conditional smoke conveying buffer channels corresponding to the No. 1 palletizing robot include a first conditional smoke conveying buffer channel a1, a second conditional smoke conveying buffer channel b1 and a third conditional smoke conveying buffer channel c1;

[0010] The four palletizing stations corresponding to the No. 1 palletizing robot include A1, A2, B1, and C1, and a1 corresponds to the A1 and A2 palletizing stations, b1 corresponds to the B1 palletizing station, and c1 corresponds to the C1 palletizing station;

[0011] The three-condition smoke conveying cache channels corresponding to the No. 2 palletizing robot include a first condition smoke conveying cache channel b2, a second condition smoke conveying cache channel a2 and a third condition smoke conveying cache channel c2. The four palletizing stations corresponding to the No. 2 palletizing robot include A3, B2, B3 and C2, and b2 corresponds to B2 and B3 palletizing stations, a2 corresponds to A3 palletizing station, and c2 corresponds to C2 palletizing station.

[0012] Optionally, the single-channel to multi-station palletizing system also includes a warehouse management system, which allocates finished cigarette pieces of different brands to different cigarette piece conveying cache channels according to the production quantities of different brands, wherein brand a is allocated to cigarette piece conveying cache channels a1 and a2, brand b is allocated to cigarette piece conveying cache channels b1 and b2, and brand c is allocated to cigarette piece conveying cache channels c1 and c2, wherein the production quantity of brand a is greater than the production quantity of brand b, and the production quantity of brand b is greater than the production quantity of brand c.

[0013] Optionally, the warehouse management system sends the production task information to the electronic control system, and the electronic control system controls the finished cigarette pieces to flow into corresponding cigarette piece conveying buffer channels.

[0014] According to a second aspect of the present invention, a single-channel to multi-station palletizing method is provided, comprising the following steps:

[0015] Production plan allocation step: allocate finished cigarette pieces of different brands to different cigarette piece conveying and buffering channels according to the production quantity of different brands, wherein brand a is allocated to cigarette piece conveying and buffering channels a1 and a2, brand b is allocated to cigarette piece conveying and buffering channels b1 and b2, and brand c is allocated to cigarette piece conveying and buffering channels c1 and c2;

[0016] Different brands of cigarettes are stacked in different steps. When stacking cigarettes of different brands, different conveying buffer channels will give priority to corresponding parts of the stacking stations, and temporary allocation and priority stacking will be carried out according to the throughput of cigarettes in each channel and the shortage of stations.

[0017] Optionally, the steps of stacking cigarettes of different brands specifically include:

[0018] When stacking brand a cigarettes, channel a1 corresponds to A1 and A2 stations first. When A1 station is completed, channel a2 starts to receive and detect the number of cigarettes at A3 station. If channel a1 is overloaded, channel a2 will be transferred to A3 station for stacking. If A3 station is short of less than 10 cigarettes, it will be stacked first. At the same time, if channel a2 is overloaded, channel a1 will be transferred to A2 station for stacking. Channel a1 corresponds to A1 and A2 stations first, and channel a2 is used as a backup channel to receive cigarettes after channel a1 is full.

[0019] When palletizing brand b cigarettes, channel b2 corresponds to stations B2 and B3 first. After station B2 is completed, channel b1 starts to receive and detect the number of cigarettes at station B1. If channel b2 is overloaded, channel b1 will be transferred to station B1 for palletizing. If station B1 is short of less than 10 cigarettes, palletizing will be prioritized. At the same time, if channel b1 is overloaded, channel b2 will be transferred to station B2 for palletizing. Channel b2 corresponds to stations B2 and B3 first, and channel b1 is used as a backup channel to receive cigarettes after b2 is full.

[0020] When palletizing c brand cigarettes, channel c1 corresponds to station c1. After c1 is completed, it will be transferred to station c2. Station c1 and c2 will perform palletizing operations alternately.

[0021] The single-channel to multi-station palletizing system and method disclosed in the present invention has the following technical effects:

[0022] The present invention is equipped with two stacking robots, and a corresponding number of cigarette conveying buffer channels and stacking stations are allocated to each robot, so that each stacking robot can perform its duties and process cigarettes from different sources in an orderly manner, thus avoiding confusion in task allocation, optimizing the resource allocation of the system as a whole, and improving equipment utilization;

[0023] For the three brands of a, b, and c with different production volumes in normal production, different cigarette delivery buffer channels are allocated to them according to their production volumes, and the priority of each channel is set. The delivery resources can be reasonably allocated according to the brand production volume, and the brand cigarettes with large production volumes are given priority to have more efficient delivery paths, thus avoiding the possible delivery congestion caused by the shared channels of various brands and improving the overall cigarette delivery efficiency;

[0024] Reasonable arrangement of the stacking sequence can avoid long-term idleness of the stacking station or excessive accumulation and congestion at a certain station. For example, in the process of stacking brand A, when A1 is full, the situation of A3 is promptly checked to decide whether to stack A2 or A3 first, so that the number of cigarettes at each station can be kept relatively balanced.

[0025] Further features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the present invention with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0031] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0033] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0034] The present invention proposes an embodiment of a single-channel to multi-station palletizing system. Specifically, Figure 1 shown, including:

[0035] There are two palletizing robots, namely palletizing robot No. 1 and palletizing robot No. 2; the two robots can carry out palletizing work at the same time. Compared with a single robot operation, they can handle palletizing tasks in parallel, greatly improving the efficiency of the overall palletizing operation.

[0036] Conveying buffer channel: Three conditioned smoke conveying buffer channels are respectively configured for the No. 1 palletizing robot and the No. 2 palletizing robot, and one conditioned smoke reflux channel is additionally configured for the No. 1 palletizing robot; when there is a need for fallback processing, the conditioned smoke can be returned through the reflux channel, effectively avoiding material waste.

[0037] Multiple palletizing stations: The No. 1 palletizing robot corresponds to 4 palletizing stations, which are set as A1, A2, B1, and C1 respectively. The 4 palletizing stations A1, A2, B1, and C1 are set around the No. 1 palletizing robot; the No. 2 palletizing robot corresponds to 4 palletizing stations, which are set as A3, B2, B3, and C2 respectively. The 4 palletizing stations A3, B2, B3, and C2 are set around the No. 2 palletizing robot. This interval station layout around the robot makes full use of the space around the robot, so that the palletizing operation can be carried out in an orderly manner in multiple directions, which is convenient for the robot's mechanical arm and other components to operate each station and reduce unnecessary movement paths.

[0038] The system of this embodiment can flexibly allocate materials transported by each conveying buffer channel to the corresponding palletizing station according to different production plans, product types, order requirements, etc. The setting of multiple stations and multiple conveying buffer channels is equivalent to building a redundancy mechanism for the entire palletizing system, which improves the efficiency of palletizing operations from multiple dimensions.

[0039] In the embodiment of the present invention, the three conditional smoke conveying buffer channels corresponding to the No. 1 palletizing robot include a first conditional smoke conveying buffer channel a1, a second conditional smoke conveying buffer channel b1 and a third conditional smoke conveying buffer channel c1;

[0040] The four palletizing stations corresponding to the No. 1 palletizing robot include A1, A2, B1, and C1, and a1 corresponds to the A1 and A2 palletizing stations, b1 corresponds to the B1 palletizing station, and c1 corresponds to the C1 palletizing station;

[0041] The three conditional smoke conveying and buffering channels corresponding to the No. 2 palletizing robot include the first conditional smoke conveying and buffering channel b2, the second conditional smoke conveying and buffering channel a2 and the third conditional smoke conveying and buffering channel c2. The four palletizing stations corresponding to the No. 2 palletizing robot include A3, B2, B3 and C2, and b2 corresponds to B2 and B3 palletizing stations, a2 corresponds to A3 palletizing station, and c2 corresponds to C2 palletizing station. The clear correspondence enables the operator or warehouse management system to accurately know which specific palletizing station the smoke in each conveying and buffering channel should flow to during the entire smoke conveying, buffering and subsequent palletizing process, so as to facilitate the orderly and accurate control of the material flow. The entire palletizing process can be carried out in parallel, which improves the overall work efficiency.

[0042] In an embodiment of the present invention, the single-channel to multi-station stacking system also includes a warehouse management system, which allocates finished cigarette pieces of different brands to different cigarette conveying and buffering channels according to the production quantities of different brands, thereby realizing accurate diversion of cigarette pieces of different brands in the conveying link. Among them, brand a is allocated to the cigarette conveying and buffering channels a1 and a2, brand b is allocated to the cigarette conveying and buffering channels b1 and b2, and brand c is allocated to the cigarette conveying and buffering channels c1 and c2, wherein the production quantity of brand a is greater than the production quantity of brand b, and the production quantity of brand b is greater than the production quantity of brand c. Considering the differences in the production quantities of different brands, resources can be effectively optimized through such an allocation method. Brands with large production quantities correspond to more conveying and buffering channels, which can better carry and convey larger batches of finished cigarette pieces, and prevent problems such as backlog and poor conveying of cigarettes of this brand on the production line due to insufficient number of channels.

[0043] In an embodiment of the present invention, the warehouse management system sends the production task information to the electronic control system, and the electronic control system controls the finished cigarette pieces to flow into the corresponding cigarette piece conveying and caching channels. The production task information includes but is not limited to the type, quantity, and destination of the finished cigarette pieces. The electronic control system can know how to operate based on the production task information, ensuring that the subsequent finished cigarette piece conveying and caching work is strictly carried out in accordance with the established production tasks, thereby improving the accuracy and standardization of the entire operation process.

[0044] The present invention also provides an embodiment of a single-channel to multi-station palletizing method, comprising the following steps:

[0045] Production plan allocation steps: allocate different brands of finished cigarettes to different cigarette conveying buffer channels according to the production quantity of different brands, among which brand a is allocated to a1 and a2 cigarette conveying buffer channels, brand b is allocated to b1 and b2 cigarette conveying buffer channels, and brand c is allocated to c1 and c2 cigarette conveying buffer channels. The method of allocating conveying buffer channels by brand makes it easier to control the quantity of different brands of cigarettes, track their flow, monitor production progress and other management tasks during the production process.

[0046] Different brands of cigarette palletizing steps, different conveying buffer channels give priority to corresponding parts of the palletizing stations when palletizing different brands of cigarette pallets, and temporary allocation and priority palletizing are performed according to the throughput of cigarette pallets in each channel and the shortage of stations. If the throughput of cigarette pallets in a conveying buffer channel suddenly increases, and the corresponding priority palletizing station is close to full capacity, etc., some cigarette pallets can be temporarily allocated to other relatively idle palletizing stations in time, avoiding the problem of cigarette pallet accumulation and palletizing stagnation due to local station shortage, and making full use of all available palletizing station resources to ensure the continuity and efficiency of palletizing work.

[0047] In the embodiment of the present invention, the steps of stacking cigarettes of different brands specifically include:

[0048] When stacking brand a cigarettes, channel a1 corresponds to A1 and A2 stations first. When A1 station is completed, channel a2 starts to receive and detect the number of cigarettes at A3 station. If channel a1 is overloaded, channel a2 will be transferred to A3 station for stacking. If A3 station is short of less than 10 cigarettes, it will be stacked first. At the same time, if channel a2 is overloaded, channel a1 will be transferred to A2 station for stacking. Channel a1 corresponds to A1 and A2 stations first, and channel a2 is used as a backup channel to receive cigarettes after channel a1 is full.

[0049] When palletizing b-brand cigarettes, channel b2 corresponds to B2 and B3 stations first. After B2 station is completed, channel b1 starts to receive and detect the number of cigarettes at B1 station. If channel b2 has excess, it will be transferred to channel b1 for palletizing at B1 station. If B1 station is short of less than 10 cigarettes, it will be given priority for palletizing. At the same time, if channel b1 has excess, it will be transferred to channel b2 for palletizing at B2 station. Channel b2 corresponds to B2 and B3 stations first. b1 is used as a backup channel to receive cigarettes after b2 is full.

[0050] When stacking brand c cigarettes, channel c1 corresponds to station c1, and after c1 is stacked, it will be transferred to station c2, and stations c1 and c2 will perform stacking operations alternately. It should be noted that in actual production, a small amount of cigarette shortages may occur from time to time. Through the strategy of priority stacking, the number of cigarettes on the station can be replenished as soon as possible, the continuity of stacking can be maintained, the idle time of the station caused by cigarette shortage can be reduced, and the stacking efficiency can be improved.

[0051] In another embodiment of the present invention, Figure 1 The single-channel to multi-station palletizing method includes the following processes, specifically:

[0052] Step 1: After receiving the production schedule for the day, the operator allocates different brands of finished cigarettes to different cigarette conveying buffer channels in the management system according to the production quantity of different brands. Brand a with the largest output is allocated to cigarette conveying buffer channels a1 and a2, brand b with moderate output is allocated to cigarette conveying buffer channels b1 and b2, and brand c with the smallest output is allocated to cigarette conveying buffer channels c1 and c2. The management system sends the task information to the electronic control system, which controls the flow of finished cigarettes into different cigarette conveying buffer channels.

[0053] Step 2: When producing brand a cigarettes, the a1 cigarette conveyor buffer channel gives priority to receiving brand a cigarettes, which corresponds to palletizing stations A1 and A2. After the palletizing of station A1 is completed, the a2 cigarette conveyor buffer channel receives brand a cigarettes and detects the number of cigarettes on the actual pallet of station A3 cigarettes at the same time (the a1 cigarette conveyor buffer channel inputs an excessive amount of brand a cigarettes, which are temporarily allocated to the a2 cigarette conveyor buffer channel and palletized at station A3). If the number of cigarettes on the actual pallet of station A3 cigarettes is less than 10 pieces, it is given priority. Palletize the A3 station first (the a brand cigarettes input into the a2 cigarette conveyor buffer channel are excessive, so they are temporarily allocated to the a1 cigarette conveyor buffer channel, and palletize the A2 station); after the A3 station is palletized, the A2 station is palletized. After the A2 station is palletized, the a2 cigarette conveyor buffer channel receives the a brand cigarettes, and at the same time detects the number of cigarettes on the A3 station cigarette pallet. If the number of cigarettes on the A3 station cigarette pallet is less than 10, the A3 station is palletized first, and the A1 station is palletized at the same time. The a1 cigarette conveyor buffer channel corresponds to the palletizing stations A1 and A2 first, and the a2 cigarette conveyor buffer channel is a backup channel. After the a1 cigarette conveyor buffer channel is full of cigarettes, cigarettes are input into the a2 cigarette conveyor buffer channel.

[0054] When producing brand b cigarettes, the b2 cigarette conveyor buffer channel gives priority to receiving brand b cigarettes, which corresponds to palletizing stations B2 and B3. After palletizing at station B2 is completed, the b1 cigarette conveyor buffer channel receives brand b cigarettes and detects the number of cigarettes on the pallet at station B1 at the same time (the b2 cigarette conveyor buffer channel inputs an excess of brand b cigarettes, which are temporarily allocated to the b1 cigarette conveyor buffer channel and palletized at station B1). If the number of cigarettes on the pallet at station B1 is less than 10, it will be given priority. Palletizing at B1 station (the b brand cigarettes input into the b1 cigarette conveying buffer channel are excessive, and are temporarily allocated to the b2 cigarette conveying buffer channel, and palletizing is performed at B2 station); after palletizing at B1 station, palletizing is performed at B3 station. After palletizing at B3 station, the b1 cigarette conveying buffer channel receives the b brand cigarettes, and at the same time detects the number of cigarettes on the actual pallet of the cigarettes at B1 station. If the number of cigarettes on the actual pallet of the cigarettes at B1 station is less than 10 pieces, palletizing at B1 station is prioritized, and palletizing is performed at B2 station at the same time. The b2 cigarette conveying buffer channel corresponds to palletizing stations B2 and B3 first, and the b1 cigarette conveying buffer channel is a backup channel. After the b2 cigarette conveying channel is full of cigarettes, cigarettes are input into the b1 cigarette conveying buffer channel, and the b1 cigarette conveying channel is mostly empty.

[0055] When producing c brand cigarettes, the c1 cigarette conveying channel corresponds to the palletizing station C1, and the c2 cigarette conveying channel corresponds to the palletizing station C2; after the C1 station palletizing is completed, the C2 station palletizing is carried out, and C1 and C2 are palletized alternately.

[0056] In general, the palletizing steps of different brands are set, so that the entire palletizing system can flexibly respond to various situations faced by different brands of cigarettes in actual production, such as flow changes in different channels, lack of cigarettes at workstations, and different palletizing rhythm requirements. Whether it is the complementarity and flow control of multiple channels of brand A, the similar channel collaboration of brand B, or the alternating operation of brand C workstations, it can adapt to a variety of complex production scenarios and ensure that all brands of cigarettes can be palletized efficiently and orderly. Even if there are local fluctuations or changes in the production process, the system can quickly adjust to maintain the stable operation of the overall production.

[0057] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the present invention is not limited to the scope of implementation shown in the drawings, and all changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the specification and drawings, should be within the protection scope of the present invention.
