Description

Technical Field

[0001] The present invention relates to the technical field of food and drug packaging machinery and equipment, and particularly relates to an automatic scheduling method for packaging material logistics and a packaging material logistics scheduling system. Background Art

[0002] In an automatic packaging material conveying system, since the unboxing machine has a fast beat, when the conveying line system conveys packaging materials to meet the working beat of the palletizing machine, there should be no blockage or non-conveyance of packaging materials. However, in traditional conveying line control methods, generally, goods are conveyed singly, and it is very difficult to allocate the destination of goods on the conveying line in real time. Therefore, it is impossible to ensure that the conveying line does not get blocked or there is no non-conveyance of packaging materials. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an automatic scheduling method for packaging material logistics and a packaging material logistics scheduling system that can achieve real-time allocation of packaging materials, prevent blockage of the conveying line, and improve production efficiency.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0005] An automatic scheduling method for packaging material logistics, comprising the following steps:

[0006] Judge the status of the unboxing machine: Starting from the feeding port of the conveying line, cyclically judge whether there is any packaging material on each unboxing machine from far to near. If not, replenish the material. If so, prepare the material, and the replenishment priority is higher than the preparation of materials;

[0007] The replenishment is as follows: The position section corresponding to the conveying line and the unboxing machine is set as the conveying decision section. Judge whether the packaging materials on the conveying decision section meet the conditions of having packaging materials and the packaging materials not being locked. If they meet, lock the packaging materials and send them to the unboxing machine without packaging materials. If they do not meet, cyclically obtain the status of the packaging materials on each conveying decision section from far to near until packaging materials that meet the conditions are obtained;

[0008] The preparation of materials is as follows: Judge whether the quantity of packaging materials on each unboxing machine reaches the predetermined quantity. If it does not reach the predetermined quantity, send the unlocked packaging materials on the conveying line to this unboxing machine.

[0009] As a further improvement of the above technical solution:

[0010] For the unlocked packaging materials on the conveying line in the preparation of materials, they are obtained by adopting a cyclical method from far to near, starting from the feeding port of the conveying line and ending at the conveying decision section corresponding to the unboxing machine that has not reached the predetermined quantity.

[0011] In the judgment of the status of the unboxing machine, only the status of one unboxing machine is judged at a time to judge whether there is any packaging material on this unboxing machine.

[0012] The state of whether there is packaging material on the decartoning machine is detected by a sensor.

[0013] Sensors are installed on each conveying decision section, and the destination of the packaging materials is determined by sensing signals from two sensors on adjacent conveying line sections.

[0014] The predetermined number of packaging materials on the decartoning machine is set to three.

[0015] A packaging material logistics dispatching system comprises a conveyor line and a plurality of carton removers arranged at intervals along the conveyor line. The position sections corresponding to the conveyor line and the carton removers are set as conveying decision sections. Each of the conveying decision sections is provided with a separate driving device. A packaging material detection part is provided on the conveying decision section.

[0016] As a further improvement of the above technical solution:

[0017] The packaging material detection component is a sensor.

[0018] The number of the depackaging machines is eight.

[0019] Compared with the prior art, the advantages of the present invention are:

[0027] The present invention will be further described in detail below in conjunction with the specification drawings and specific embodiments.

[0028] Embodiment 1:

[0029] Figure 1 An embodiment of the automatic scheduling method for packaging material logistics of the present invention is shown. The automatic scheduling method for packaging material logistics includes the following steps:

[0030] Judge the state of the unboxing machine 2: Starting from the feeding port of the conveyor line 1, judge whether there is any packaging material on each unboxing machine 2 in a cycle from far to near. If there is none, replenish the material. If there is any, prepare the material, and the replenishment priority is higher than the preparation of materials (replenish the material first and then prepare the material);

[0031] Replenishment of materials: The position section corresponding to the conveyor line 1 and the unboxing machine 2 is set as the conveyor decision section 11. Judge whether the packaging material on the conveyor decision section 11 meets the conditions that there is packaging material and the packaging material is not locked. If it meets the conditions, lock the packaging material and send it to the unboxing machine 2 without packaging material. If it does not meet the conditions, obtain the status of the packaging material on each conveyor decision section 11 in a cycle from far to near until the packaging material that meets the conditions is obtained;

[0032] Preparation of materials: Judge whether the quantity of the packaging material on each unboxing machine 2 reaches the predetermined quantity. If it does not reach the predetermined quantity, send the unlocked packaging material on the conveyor line 1 to the unboxing machine 2.

[0033] If the packaging material is locked, it means that the destination of the packaging material has been determined and cannot be changed. If the packaging material is not locked, it means that the destination (direction) of the packaging material can be changed and can be used for replenishing materials and preparing materials.

[0034] Automatic dispatch and allocation of carton unpacking machine 2 when it is short of materials: put the packaging materials into the feeding port of conveyor line 1, and set the position section of conveyor line 1 corresponding to carton unpacking machine 2 as conveying decision section 11. Each conveying decision section 11 is numbered B1, B2, B3...BN in the conveying direction of conveyor line 1. The carton unpacking machines 2 corresponding to the conveying decision sections 11 are numbered C1, C2, C3...CN in sequence. When the packaging materials are conveyed to conveying decision section 11 No. B1, the destination is allocated. At this time, the information on whether there are packaging materials for all carton unpacking machines 2 is obtained in real time from far to near in a loop, such as When there is no packaging material (lack of material) on the CN carton decartoning machine 2, obtain the BN conveying decision segment 11 corresponding to the CN carton decartoning machine 2, and circulate the status information of the packaging materials from the BN conveying decision segment 11 to the B1 conveying decision segment 11. When it is found that there is unlocked packaging material on the conveying decision segment 11, change the destination of the packaging material to the CN carton decartoning machine 2, and lock the packaging material so that its destination cannot be changed, replenish the CN carton decartoning machine 2, and so on, circulate and evenly dispatch packaging materials to each carton decartoning machine 2.

[0035] Automatic scheduling and allocation of material preparation for carton decartoner 2: When the carton decartoner 2 equipment is turned on and there is no shortage of materials, the number of packaging materials on each carton decartoner 2 and the locking status of the packaging materials on the conveyor line 1 are obtained in a circular manner from far to near. If CN carton decartoner 2 is enabled and the number of packaging materials on CN carton decartoner 2 is less than the predetermined number, find the unlocked packaging material closest to the BN conveying decision section 11 corresponding to CN carton decartoner 2 on conveyor line 1, change the destination of the packaging material to CN carton decartoner 2, prepare materials for CN carton decartoner 2, and so on, prepare materials for each carton decartoner 2.

[0036] The automatic scheduling method for packaging material logistics of the present invention can solve the single-destination transportation problem of the traditional conveyor line 1. According to the real-time acquisition of the operating status of the unpacking machine 2, the transportation destination of the packaging material on the conveyor line 1 can be changed in real time, thereby avoiding the problem of the unpacking machine 2 stopping due to lack of materials due to the blockage of the conveyor line 1.

[0037] The packaging material logistics automatic dispatching method of the present invention distributes materials to the unpacking machine 2 according to the principle of "from far to near", ensuring that the unpacking machine 2 is replenished with packaging materials in the shortest time when the materials are insufficient, thereby solving the problem of equipment shutdown of the unpacking machine 2 due to insufficient packaging material supply; greatly saving the conveying beat of the conveyor line 1, ensuring that the unpacking machine 2 will not be shut down due to lack of materials or blockage; and realizing the real-time allocation of the destination of the packaging materials on the conveyor line 1, preventing the conveyor line 1 from being blocked. The packaging material logistics automatic dispatching method can realize the real-time allocation of packaging materials, prevent the conveyor line from being blocked, and improve production efficiency.

[0038] In this embodiment, the packaging materials that are not locked on the conveyor line 1 during material preparation are obtained by taking the feed port of the conveyor line 1 as the starting point and the conveying decision section 11 corresponding to the decartoning machine 2 that has not reached the predetermined number as the end point, using a far-to-near circulation method.

[0039] Automatic scheduling and allocation of material preparation for the unpacking machine 2: When the unpacking machine 2 is turned on and there is no shortage of materials, the number of packaging materials on each unpacking machine 2 and the locked status of the packaging materials on the conveyor line 1 are cyclically obtained from far to near. If the unpacking machine 2 with the CN number is enabled and the number of packaging materials on the unpacking machine 2 with the CN number is less than the predetermined number, the BN number conveying decision section 11 corresponding to the unpacking machine 2 with the CN number is obtained. Starting from the BN number conveying decision section 11, the status information of the packaging materials is cyclically obtained in sequence to the B1 number conveying decision section 11. When an unpacked packaging material is found on the conveying decision section 11, the destination of the packaging material is changed to the unpacking machine 2 with the CN number (the destination of the packaging material is not locked, so that its destination can be changed again to meet the requirement of replenishing materials first), and the unpacking machine 2 with the CN number is prepared with materials. And so on, the packaging materials are evenly scheduled for each unpacking machine 2 in a cycle.

[0040] In this embodiment, when judging the status of the unpacking machine 2, only the status of one unpacking machine 2 is judged at a time to determine whether there are packaging materials on the unpacking machine 2. Specifically, first, only the status of the unpacking machine 2 farthest from the feeding port of the conveyor line 1 is obtained to determine whether there are packaging materials on the farthest unpacking machine 2, and then the status of other unpacking machines 2 is cyclically obtained from far to near. Ensure that the unpacking machine 2 receives packaging material replenishment within the shortest time of material shortage.

[0041] In this embodiment, the status of whether there are packaging materials on the unpacking machine 2 is detected by sensors. Specifically, sensors are provided on each conveying decision section 11 to sense whether there are packaging materials through the sensors on the conveying decision section 11, and the direction of the packaging materials is judged by the induction signals of the two sensors on the adjacent conveying decision sections 11.

[0042] In this embodiment, the predetermined number of packaging materials on the unpacking machine 2 is set to three.

[0043] Embodiment 2:

The packaging material logistics scheduling system includes a conveyor line 1, and a plurality of decartoning machines 2 arranged at intervals along the conveyor line 1. The position section corresponding to the conveyor line 1 and the decartoning machine is set as a conveying decision section 11. The conveying decision section 11 is provided with a separate driving device, and a packaging material detection part 3 is provided on the conveying decision section 11. When in use, starting from the feed port of the conveyor line 1, a cycle is made from far to near to determine whether there are packaging materials on each decartoning machine 2. If not, refill the material. If so, prepare the material, and the priority of refilling the material is higher than that of preparing the material. Refilling process: The position section corresponding to the conveyor line 1 and the decartoning machine 2 is set as the conveying decision section 11, and it is determined whether the packaging material on the conveying decision section 11 meets the conditions that there is packaging material and the packaging material is not locked. If it meets the conditions, the packaging material is locked and sent to the decartoning machine 2 without packaging material. If it does not meet the conditions, the status of the packaging material on each conveying decision section 11 is obtained from far to near until the packaging material that meets the conditions is obtained. Material preparation process: determine whether the quantity of packaging materials on each decartoning machine 2 has reached a predetermined quantity. If it has not reached the predetermined quantity, the packaging materials that are not locked on the conveyor line 1 are sent to the decartoning machine 2.

[0045] The packaging material logistics dispatching system of the present invention can distribute materials to the unpacking machine 2 according to the principle of "from far to near", ensuring that the unpacking machine 2 is replenished with packaging materials in the shortest time when the materials are insufficient, thus solving the problem of equipment shutdown of the unpacking machine 2 due to insufficient packaging material supply; it greatly saves the conveying beat of the conveyor line 1, ensuring that the unpacking machine 2 will not be shut down due to lack of materials or blockage. The packaging material logistics dispatching system can realize real-time distribution of packaging materials, prevent blockage of the conveyor line, and improve production efficiency.

[0046] In this embodiment, the packaging material detection element 3 is a sensor. The sensor on the conveying decision section 11 senses whether there is packaging material, and the sensing signals of two sensors on adjacent conveying decision sections 11 are used to determine the destination of the packaging material.

[0047] In this embodiment, the number of the unpacking machines 2 is eight.
