The storage streamline dispatching system is not limited to be applied to the catering industry, the logistics sorting industry and the like, and the following description mainly takes the application to the catering industry as an example. Wherein, the discharging conveying line 100 is used for conveying materials to a specified position, for example, a table position for customers to have meals can be arranged on two sides of the discharging conveying line 100 or at the tail end of the discharging conveying line 100, and the discharging conveying line 100 can be used for conveying meals to the specified table position. The discharging conveying lines 100 include, but are not limited to, belt conveying lines, roller conveying lines, etc., the specific shape of the discharging conveying lines 100 may be set to be linear, curved, or annular, etc. according to the actual site, and the number of the discharging conveying lines 100 may also be set to be one, two, or more as required. The storage warehouse 200 is used for storing materials (e.g. meal), and according to a storage environment actually required by the materials, the storage warehouse 200 includes, but is not limited to, a cold storage warehouse or an incubator, and the material taking mechanism is used for taking out and transferring the materials in the storage warehouse 200 to a preset position of the transfer conveyor line 300, where the preset position may be specifically a connection position between one side of the transfer conveyor line 300 away from the storage warehouse 200 and the corresponding discharge conveyor line 100. The material taking mechanism comprises, but is not limited to, a multi-axis manipulator or a combination of a mechanical clamping jaw and a multi-axis linear module to clamp and release materials in a three-dimensional space. Transfer chain 300 is used for forming the material transfer place between storage silo 200 and the ejection of compact transfer chain 100, and transfer chain 300 is the annular setting for the material can be in the reciprocating transport on transfer chain 300, avoids producing to block up. The controller is used for forming a control center of the warehouse logistics scheduling system to ensure that the storage warehouse 200, the transfer conveying line 300 and the discharge conveying line 100 run orderly, so that the ordered scheduling and conveying of materials are realized. The controller includes but is not limited to a PLC controller or a micro-controller computer, etc.
When the warehouse storage streamline dispatching system works, according to an efficiency priority principle, the screening module preferentially determines the storage warehouse 200 with the closest conveying distance as a target storage warehouse, the control module controls the corresponding material taking mechanism to take out materials (such as dishes) in the target storage warehouse and transfer the materials to a connection position of the transfer conveying line 300, the control module controls the material pushing mechanism to push the materials to the discharging conveying line 100, and then the materials can be conveyed to a specified position (such as a dining table position) through the discharging conveying line 100; when the storage warehouse 200 with the closest conveying distance does not have the required target material, the screening module determines the storage warehouse 200 with the next adjacent conveying distance as the target storage warehouse, the corresponding material taking mechanism calls the material out of the target storage warehouse to the preset position of the transfer conveying line 300, and when the material flows to the connection position with the discharge conveying line 100 through the transfer conveying line 300, the material can be pushed to the discharge conveying line 100 through the material pushing mechanism. The warehouse storage streamline dispatching system can realize the mutual dispatching of the stocks among the storage warehouses 200, thereby effectively improving the utilization rate and the flexibility of the storage warehouses 200, receiving the materials in the storage warehouses 200 by the discharging conveying line 100, and effectively avoiding the problem of material shortage caused by single-line one-to-one dispatching.
In one embodiment, the number of the discharging conveyor lines 100 is the same as that of the storage bins 200, the discharging conveyor lines 100 and the storage bins 200 are correspondingly arranged on two opposite sides of the outer ring of the transfer conveyor line 300, and the transfer conveyor line 300 is provided with a pushing mechanism corresponding to the connection position of each discharging conveyor line 100. Therefore, different discharging conveying lines 100 can receive the materials of the storage warehouses 200, and the utilization rate of the storage warehouses 200 is further improved.
For example, as shown in fig. 2, in the present embodiment, there are four storage warehouses 200, which are respectively marked as a storage warehouse a, a storage warehouse B, a storage warehouse C, and a storage warehouse D, the four storage warehouses 200 are sequentially arranged on the same side of the transfer conveyor line 300, and four discharge conveyor lines 100 are correspondingly arranged on the other side of the transfer conveyor line 300, which are respectively marked as a discharge conveyor line a, a discharge conveyor line B, a discharge conveyor line C, and a discharge conveyor line D. The material taking mechanism on each storage warehouse 200 can take out and convey the materials in the corresponding storage warehouse 200 to the connection position between the transfer conveyor line 300 and the corresponding discharge conveyor line 100, for example, the material taking mechanism on the storage warehouse a can take out and convey the materials in the storage warehouse a to the connection position between the transfer conveyor line 300 and the discharge conveyor line a, the material taking mechanism on the storage warehouse B can take out and convey the materials in the storage warehouse B to the connection position between the transfer conveyor line 300 and the discharge conveyor line B, and so on.
When a customer on the corresponding table position of the discharging conveying line D orders food (for example, the customer can scan a code through a desktop to order food), the warehouse storage streamline dispatching system starts to operate, according to an efficiency priority principle, the screening module preferentially determines the storage warehouse D as a target storage warehouse, the control module controls the material taking mechanism on the storage warehouse D to take out and transfer food in the storage warehouse D to a connection position of the discharging conveying line D and the storage warehouse D, the food is directly pushed to the discharging conveying line D through the material pushing mechanism at the position, and the food is conveyed to the corresponding ordering table position through the discharging conveying line D. If there is no desired target meal in the storage warehouse D, the screening module selects the storage warehouse 200 storing the target meal, and the storage warehouse 200 closest to the conveying direction of the transfer conveyor line 300 is used as the target storage warehouse, it should be noted that the conveying distance here is determined based on the conveying direction of the transfer conveyor line 300, for example, as shown in fig. 2, the transfer conveyor line 300 is conveyed counterclockwise, the conveying distance corresponding to the storage warehouse C is the linear distance from the connection position of the transfer conveyor line 300 and the discharge conveyor line C to the connection position of the transfer conveyor line 300 and the discharge conveyor line D, the conveying distance corresponding to the storage warehouse B is the linear distance from the connection position of the transfer conveyor line 300 and the discharge conveyor line B to the connection position of the transfer conveyor line 300 and the discharge conveyor line D, and the conveying distance corresponding to the storage warehouse a is the linear distance from the connection position of the transfer conveyor line 300 and the connection position of the discharge conveyor line a to the connection position of the transfer conveyor line 300 and the discharge conveyor line D The line distance, because the transfer conveyor line 300 is transported counterclockwise, can determine that the conveying distance between the storage warehouse C and the discharging conveyor line D is the closest. It can be understood that when the transfer conveyor line is conveying clockwise, the conveying distance between the storage warehouse a and the discharge conveyor line D is the closest.
Alternatively, each of the discharging conveyor lines 100 is an elongated annular conveyor line, and each of the discharging conveyor lines 100 is arranged in parallel and at intervals in the extending direction of the transfer conveyor line 300. Thus, a plurality of tables can be sequentially arranged on two sides of the discharging conveying line 100, so that dining service can be provided for more customers at the same time.
Further, an information identification module electrically connected with the controller is further arranged on the transfer conveying line 300, and the information identification module is used for identifying the information of the materials; the warehouse logistics line dispatching system further comprises a recycling mechanism electrically connected with the controller, and the recycling mechanism is used for recycling materials with abnormality on the transfer conveying line 300. The materials on the transfer conveying line 300 are subjected to information identification through the information identification module, and when the information identification module identifies that the number of circles of the same material circularly conveyed on the transfer conveying line 300 exceeds a preset threshold value, the controller can control the recovery mechanism to recover the materials on the transfer conveying line 300. So, can avoid unusual material to pile up on transfer chain 300, lead to transfer chain 300 to take place to block up after long-time. The information identification module can specifically adopt an RFID (radio frequency identification) technology to identify information, and correspondingly, a chip for storing material information is arranged on the material.
Further, the warehouse logistics scheduling system further comprises an alarm module electrically connected with the controller, and the alarm module is used for sending a replenishment signal when each storage warehouse 200 cannot provide target materials. The concrete accessible of alarm module sends prompt tone or signal lamp flashing light and forms and sends the replenishment signal to make the staff can in time supply the material in the storage silo 200, thereby can satisfy customer's dining demand.
Based on the storage streamline dispatching system, the invention also provides a storage streamline dispatching method, which comprises the following steps:
s1, receiving a food ordering instruction, and reading a target food and a food ordering table position contained in the food ordering instruction;
s2, setting the discharge conveyor line 100 corresponding to the ordering table position as a target discharge conveyor line, and determining one of the storage warehouses 200 as a target storage warehouse according to preset conditions; wherein the preset conditions are as follows: the target storage warehouse stores the target meal, and compared with other storage warehouses 200 storing the target meal, the conveying distance between the target storage warehouse and the target discharging conveying line is the shortest;
s3, controlling the material taking mechanism to take out the target meal from the target storage warehouse and transfer the target meal to a preset position of the transfer conveyor line 300;
and S4, when the target meal is located at the connection position of the transfer conveying line 300 and the target discharging conveying line, controlling the material pushing mechanism to push the target meal to the target discharging conveying line.
Specifically, the storage streamline dispatching system shown in fig. 2 is taken as an example for explanation, and for convenience of explanation, the transfer conveyor line 300 is set to be a counterclockwise conveying in this embodiment, but it should not be construed as limiting the scope of the present invention.
When the discharging conveying line D corresponds to a customer on the table for ordering (for example, the customer can scan a code and order through a desktop), the controller receives an ordering instruction to control the warehouse storage streamline dispatching system to start running, the discharging conveying line D is the target discharging conveying line at the moment, and the materials called out from the storage warehouse 200 finally need to be conveyed to the discharging conveying line D.
If the storage warehouse D stores the required target meal, the storage warehouse D is the target storage warehouse, the material taking mechanism takes the meal from the storage warehouse D and transfers the meal to the connection position of the transfer conveyor line 300 and the discharge conveyor line D (the connection position is a preset position), the target meal is directly pushed to the discharge conveyor line D through the material pushing mechanism, and then the target meal is conveyed to the corresponding ordering table through the discharge conveyor line D.
If the storage warehouse D does not have the required target meal, the screening module determines one of the storage warehouse A, the storage warehouse B and the storage warehouse C as a target storage warehouse according to preset conditions. The preset conditions are as follows: the target storage warehouse is stored with the target meal, and compared with other storage warehouses 200 stored with the target meal, the conveying distance between the target storage warehouse and the target discharging conveying line is the shortest. For example, if the target meal is stored in each of the storage warehouse a, the storage warehouse B and the storage warehouse C, and the conveying distance of the storage warehouse C is shortest, the storage warehouse C is determined to be the target storage warehouse; and if only the target food is stored in the storage warehouse A, determining the storage warehouse A as the target storage warehouse. It should be noted that the conveying distance is determined based on the conveying direction of the transfer conveying line 300, and the specific determination method can refer to the foregoing, and is not described herein again.
For example, when there is no required target meal in the storage warehouse D and it is determined that the storage warehouse C is the target storage warehouse, the material taking mechanism takes out the target meal from the storage warehouse C and transfers the target meal to the connection position between the transfer conveyor line 300 and the discharge conveyor line C (the connection position here is a preset position), the target meal is transported to the connection position between the transfer conveyor line 300 and the discharge conveyor line D, the meal is pushed to the discharge conveyor line D by the material pushing mechanism here, and the target meal is transported to the corresponding ordering table position by the discharge conveyor line D.
The warehouse storage streamline scheduling method can realize the mutual scheduling of the stocks among the storage warehouses 200, thereby effectively improving the utilization rate and the flexibility of the storage warehouses 200, receiving the materials in the storage warehouses 200 by the discharging conveying line 100, and effectively avoiding the problem of material shortage caused by single-line one-to-one scheduling; the in-situ conveying can be realized by the storage streamline scheduling method, and the conveying efficiency of materials can be effectively improved; in addition, transfer chain 300 is the annular setting for the material can be in the reciprocating transport on transfer chain 300, avoids producing and blocks up.
Further, the following steps are also included after the step S4:
and S5, controlling the target discharging conveying line to convey the target food to the ordering table.
Optionally, each corresponding table position on the discharging conveying line 100 is provided with a meal outlet, the meal outlet is provided with a meal outlet pushing mechanism, when a target meal product moves to the meal outlet corresponding to the meal ordering table position along the discharging conveying line 100, the target meal product is automatically pushed to the corresponding meal ordering table position through the meal outlet pushing mechanism, and therefore meal outlet efficiency can be further improved, and user experience is improved.
In one embodiment, in step S2, the specific method for determining the target storage library includes: sequencing the conveying distances between the storage warehouses 200 and the target discharging conveying line from near to far; and then sequentially judging whether the target food is stored in each storage warehouse 200 according to the sequence until the storage warehouse 200 storing the target food is determined as the target storage warehouse at first, and stopping judgment after the target storage warehouse is determined.
Specifically, please refer to fig. 2 and 4, after the table position corresponding to the discharge conveyor line D is ordered, the screening module preferentially determines whether the storage bin D has the target food, and if the target food exists, the target food is called from the storage bin D directly; if the storage warehouse D does not have the target food, judging whether the storage warehouse C with the next adjacent conveying distance has the target food, if so, calling the target food from the storage warehouse C, if not, continuously judging whether the storage warehouse B stores the target food, and so on until the target storage warehouse is screened out.
In another embodiment, in the step S2, the specific method for determining the target storage library may further include: judging whether target food products are stored in each storage warehouse 200, and taking the storage warehouse 200 in which the target food products are stored as an alternative storage warehouse; when the number of the alternative storage warehouses is 1, the alternative storage warehouses are target storage warehouses; and when the number of the alternative storage warehouses is more than or equal to 2, sequencing the conveying distances between the alternative storage warehouses and the target discharging conveying line from near to far, wherein the alternative storage warehouse with the closest conveying distance is the target storage warehouse. According to the method, the target storage warehouse can be quickly determined.
In some cases, when the meal on the transfer conveyor line 300 is abnormal and cannot be pushed to the corresponding discharge conveyor line 100 by the pushing mechanism, the abnormal meal will circulate along the transfer conveyor line 300, which will affect the conveying of the normal meal, and after a long time, the abnormal meal will be stacked to block the transfer conveyor line 300. In order to solve the above problems, the storage streamline scheduling method further includes the steps of: and judging whether the food flowing on the transfer conveying line 300 is abnormal or not, and recovering the abnormal food when the abnormality is found. Therefore, the blockage of the transfer conveying line 300 can be effectively avoided, and the normal operation of the whole warehouse logistics line dispatching system is ensured.
Further, the method for determining whether there is an abnormality in the food items flowing on the transfer line 300 includes: detecting the number of turns of the food flowing on the transfer conveying line 300, and determining that the food is abnormal when the number of turns of the food continuously flowing on the transfer conveying line 300 reaches a preset threshold value. For example, the information identification module on the transit conveyor line 300 performs information identification on the meal items on the transit conveyor line 300, and when the information identification module identifies that the number of turns of the same meal item circularly conveyed on the transit conveyor line 300 exceeds a preset threshold (for example, the preset threshold may be set to three turns), the controller may control the recycling mechanism to recycle the meal items on the transit conveyor line 300. The recycling mechanism can specifically adopt a recycling gripper to directly clamp and transfer the materials on the transfer conveying line 300 to a specified recycling position, or can also provide a recycling opening on the transfer conveying line 300, the recycling opening is correspondingly provided with a pushing mechanism, and when abnormal materials move to the recycling opening, the pushing mechanism pushes the materials out of the recycling opening to the recycling mechanism so as to enable the materials to be separated from the transfer conveying line 300.
Further, as shown in fig. 4, in an embodiment, the step S2 further includes: when it is determined that each of the material storages 200 does not store the target meal item, a replenishment signal is issued. Specifically, when the screening module determines that none of the storage warehouses 200 stores the target food, the control module controls the alarm module to send a replenishment signal. The concrete accessible of alarm module sends prompt tone or signal lamp flashing light and forms and sends the replenishment signal to make the staff can in time supply the material in the storage silo 200, in order to satisfy the customer demand of having a dinner.
