Hereinafter, an implementation example of the present disclosure will be described in detail with reference to the attached drawings.

FIG. 1 is a diagram illustrating a process of loading and using material 120 in a magazine 130 according to an embodiment.

In this specification, the material 120 may include elements for manufacturing secondary battery cells. The material 120 may have a thin thickness and a large area, such as an electrode, separator, or pouch film. The material 120 is supplied wound on a reel 120, and can be cut to a desired length (L) and loaded into the magazine 130. In Process 1 (P1), the material 120 wound on the reel 110 can be cut and loaded into the magazine 130. Process 1 (P1) can be said to be a process for producing the material 120. Process 1 (P1) may include an electrode production process, a separator production process, and a pouch film production process. For example, Process 1 (P1) is an electrode production process in which a metal plate is unwinded on the reel 110 (see arrow A), and an electrode is produced through notching, cutting, defect inspection, number counting, and loading. It can be loaded into the magazine 130. A predetermined number of produced electrodes can be loaded into the magazine 130.

The material 120 loaded in the magazine 130 can be used in Process 2 (P2). Process 2 (P2) may include a process of unloading the material 120 loaded in the magazine 130 and processing or assembling the material 120. Process 2 (P2) can be said to be a process that uses the material 120 loaded in the magazine 130. Process 2 (P2) may be a vacuum dry process for processing electrodes. The magazine 130 may be used to load the material 120 produced in process 1 (P1) and transfer it to process 2 (P2). In the process of removing the magazine 130, which has exhausted the material 120, from Process 2 (P2) and combining the magazine 130 loaded with the material 120 to Process 2 (P2), non-operation of Process 2 (P2) occurs. It can happen. If only a very small amount of material 120 is loaded in the magazine 130 that supplies material 120 to process 2 (P2), the magazine 130 must be replaced frequently, so the down time of process 2 (P2) is increased. It can increase.

In process 1 (P1), when the material 120 is loaded into the magazine 130 in a set quantity, when the material 120 wound on the reel 110 is exhausted, a small amount is loaded into the last magazine 130. Only material 120 can be loaded. Since the length of the material 120 wound on the reel 110 may vary for each reel 110, and the length (L) for cutting the material 120 may also vary for each product, the magazine ( When only one set quantity is loaded into 130), only a small amount of material 120 can be loaded into the last magazine 130.

On the other hand, the device 10 for determining the loading capacity of a magazine according to an embodiment of the present disclosure can appropriately distribute a plurality of materials 120 produced from one reel 110 to a plurality of magazines 130. Since the loading capacity (C) of the magazine can be determined, it is possible to prevent the magazine 130 in which only a very small amount of material 120 is loaded. Therefore, in process 1 (P1), if the material 120 is loaded into the magazine 130 as much as the loading capacity (C) of the magazine determined according to an embodiment of the present disclosure, the magazine 130 in which only a small amount of material 120 is loaded. Since this does not occur, the magazine 130 does not need to be replaced frequently in process 2 (P2), and the non-operation time of process 2 (P2) can be minimized.

Figure 3 is a diagram illustrating a method of determining the loading capacity of a magazine according to an embodiment. Please also refer to Figure 2.

A method of determining the loading capacity of a magazine according to an embodiment includes a prediction step (S10) of obtaining the predicted number (X) of the material 120 to be produced, and the predicted number (X) of the magazine 130 (n ) to calculate the expected capacity (Cp) per magazine (S20), and a judgment step (S30) to determine whether the expected capacity (Cp) per magazine is included between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax). ), if the expected capacity (Cp) per magazine is greater than the maximum loading capacity (Cmax), the number of magazines (n) is increased by one and the calculation step (S20) is performed again (S40), and If the expected capacity per magazine (Cp) is included between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax), a decision step (S50) is performed to determine the loading capacity (C) of the magazine as the expected capacity per magazine (Cp). It can be included.

The prediction step (S10) is a process of predicting the number of materials 120 produced by cutting the continuous material 120 unwinded from the reel 110. The prediction step (S10) is observation data generated by the reel observation unit 16 observing the state of the material 120 wound on the reel 110 in order to calculate the predicted number (X) of the material 120 to be produced. A reel observation step of providing to the processor 11, and the processor 11 detects the reel 110 based on the observation data received from the reel observation unit 16 and information on the material 120 loaded in the magazine 130. It may include an acquisition step of obtaining the predicted number (X) of the producible material 120 from.

The reel observation step is a process in which the reel observation unit 16 installed in the device that produces the material 120 observes the reel 110, generates data, and provides it to the processor 11. In the reel observation step, the reel observation unit 16 measures the distance D1 between the outermost material wound on the reel 110 and the reel observation unit 16, generates observation data, and provides it to the processor 11. You can. In the reel observation step, the reel observation unit 16 can measure the weight of the reel 110 at a portion supporting the reel 110, generate observation data, and provide it to the processor 11. In the reel observation stage, the reel observation unit 16 can measure the rotation angle of the reel 110 in real time, generate observation data, and provide it to the processor 11. The observation data provided by the reel observation unit 16 to the processor 11 includes the weight of the reel 110, the distance (D1) between the outermost material wound on the reel 110 and the reel observation unit 16, and the reel observation unit 16. It may include the angle at which the reel 110 rotates and other information generated by the reel observation unit 16 observing the reel 110.

The acquisition step is a process in which the processor 11 acquires the number of materials 120 that can be produced in the reel 110 using observation data. Please refer also to Figure 1. In the acquisition step, the processor 11 determines the preset thickness of the material 120, the distance D1 between the outermost material of the reel 110 and the reel observation unit 16, the reel observation unit 16 and the reel ( 110), the length of the material 120 wound on the reel 110 is predicted using the distance (D2), and the length of the material 120 wound on the reel 110 is predicted by dividing it by the cutting length (L). You can obtain the number (X). In the acquisition step, the processor 11 calculates the distance D1 between the outermost material of the reel 110 included in the observation data and the reel observation unit 16 by using the reel observation unit (D1) stored in advance in the storage unit 12. 16) and the thickness (T1) of the reel 110 can be obtained by subtracting it from the distance (D2) between the reel 110 and the reel 110. The thickness T1 of the reel 110 is the entire thickness of the plurality of layers of the material 120 wound on the reel 110. The processor 11 may obtain the length of the material 120 wound on the reel 110 using the thickness T1 of the reel 110 and the thickness T2 of the material 120. The processor 11 divides the length of the material 120 wound on the reel 110 by the cutting length (L) of the material 120, and calculates the predicted number (X) of the material 120 that can be produced on the reel 110. It can be obtained. The length of the material 120 wound on the reel 110 may have an error for each reel 110, and a gap may be formed in the process of winding the material 120 on the reel 110, so the reel 110 The number of materials 120 that can be produced each time may be different. Therefore, one embodiment predicts how many materials 120 will be produced in the reel 110 through the prediction step (S10) and then performs a process of calculating the appropriate number to load in the magazine 130. The existence of the magazine 130, in which only a small amount is loaded, can be minimized.

The calculation step (S20) is a process in which the processor 11 calculates the expected capacity per magazine (Cp, Cp=X/n) by dividing the predicted number (X) by the number (n) of magazines 130. The expected capacity per magazine (Cp) is a value temporarily calculated to determine the loading capacity (C) of an appropriate magazine. The processor 11 may initially set the number (n) of magazines 130 to 1 and calculate the expected capacity (Cp) per magazine. When the processor 11 calculates the expected capacity (Cp) per magazine, a determination step (S30) may be performed to determine whether the expected capacity (Cp) per magazine is appropriate.

The determination step (S30) is a process in which the processor 11 determines whether the expected capacity (Cp) per magazine is included between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax). If the expected capacity (Cp) per magazine is included between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax), the processor 11 may perform the decision step (S50). If the expected capacity per magazine (Cp) is not included between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax), the processor 11 may perform the step of increasing the number of magazines (S40).

The magazine number increasing step (S40) is a process of increasing the number (n) of magazines 130 by 1. Initially, the number (n) of magazines 130 is set to 1, so in most cases, the expected capacity (Cp) per magazine exceeds the maximum loading capacity (Cmax). Therefore, the number (n) of magazines 130 is increased by 1 to increase the number (n) of magazines 130 to load the expected number of materials 120. In the magazine number increase step (S40), the processor 11 increases the number (n) of magazines 130 by 1 and performs the calculation step (S20) again.

The processor 11 may obtain an appropriate expected capacity (Cp) per magazine by repeatedly performing the calculation step (S20), the decision step (S30), and the magazine number increase step (S40). For example, if the predicted number ( If the minimum loading capacity (Cmin) is 1,200 and the maximum loading capacity (Cmax) is 1,900, in the judgment step (S30), the processor 11 determines that the estimated capacity per magazine (Cp) exceeds the maximum loading capacity (Cmax), so the magazine Perform the number increase step (S40). In the magazine number increase step (S40), the number (n) of magazines 130 is increased by 1, so the number (n) of magazines 130 becomes 2, and when the calculation step (S20) is performed, the expected capacity per magazine (Cp) becomes 8137. In the determination step (S30), the processor 11 performs the magazine number increase step (S40) again because the estimated capacity (Cp) per magazine exceeds the maximum loading capacity (Cmax). By repeating this process, the number (n) of magazines 130 becomes 9, and when the calculation step (S20) is performed, the estimated capacity of magazines 130 can be 1808. In the decision step (S30), the processor 11 can perform the decision step (S50) because the expected capacity of the magazine 130 is included between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax).

The processor 11 determines the loading capacity (C) of the magazine as the expected capacity (Cp) of the magazine when it is included between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax) of the expected capacity per magazine (Cp). The decision step (S50) can be performed. If the material 120 is loaded into the magazine 130 as much as the expected capacity (Cp) per magazine, a uniform number of materials 120 may be loaded into the plurality of magazines 130. Therefore, the magazine 130 in which only a small amount is loaded may not exist. And, even if there is some variation in the number of materials 120 that can be produced on the reel 110, the loading capacity (C) of the magazine is determined between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax), so the last magazine (130 ), there is no problem even if a slightly larger amount of material 120 or a slightly smaller amount of material 120 is loaded. Therefore, even if there is a difference between the predicted number (X) and the actual number of materials 120 actually produced, the number (n) of magazines 130 loading the materials 120 may not change.

The processor 11 may determine the loading capacity (C) of the magazine and provide the determined loading capacity (C) of the magazine to the device that produces the material 120. The device for producing the material 120 may start production to load the magazine 130 with the material 120 equal to the loading capacity (C) of the magazine.

The method of determining the loading capacity of the magazine includes, after the prediction step (S10), a step (S11) of comparing the predicted number (X) with the minimum loading capacity (Cmin) of the magazine 130, and the predicted number (X) If it is less than the minimum loading capacity of the magazine 130 (Y), a step (S12) of determining to load all the materials 120 to be produced into one magazine 130 may be further included. The processor may perform the calculation step (S20) when the predicted number (X) exceeds the minimum loading capacity (Cmin) (N).

The processor 11 may perform a step (S11) of comparing the minimum loading capacity (Cmin) of the magazine 130 and the predicted number (X). If the predicted number (X) is less than the minimum loading capacity (Cmin) of the magazine 130 (Y), the processor 11 loads all of the materials 120 as much as the predicted number (X) into one magazine 130. Therefore, it is possible to determine (S12) to load the material 120 into one magazine 130 without separately calculating the loading capacity (C) of the magazine. When the processor 11 determines to load all the materials 120 to be produced into one magazine 130 (S12), the content is transmitted to the material production device, and the material production device can start production.

The method of determining the loading capacity of the magazine is to determine whether the number (n) of magazines 130 exceeds a set number after the magazine increasing step (S40), and if the number (n) of magazines 130 is less than or equal to a set number. In the case where the repetitive inspection step (S41) of performing the calculation step (S20), and the number (n) of magazines (130) exceeds the set number, the loading capacity (C) of the magazine is equal to the maximum loading capacity (Cmax) It may include a repetition exit step (S42) of escaping repetition by making a decision.

The processor 11 may perform the repetitive check step (S41) after the magazine number increase step (S40) to determine whether the increased number (n) of magazines 130 exceeds a predetermined number. If the increased number (n) of magazines 130 is less than or equal to a predetermined number (Y), the processor 11 may repeatedly calculate the expected capacity (Cp) per magazine by performing the calculation step (S20).

When the increased number (n) of magazines 130 exceeds the predetermined number (N), the processor 11 may determine the loading capacity (C) of the magazine as the maximum loading capacity (Cmax) (S42). The iteration exit step (S42) is to escape from the iteration of calculating the expected capacity (Cp) per magazine.

The minimum load capacity (Cmin) and maximum load capacity (Cmax) are values pre-stored in the storage unit 12, and can be set to various values because they are values input by the user. The predicted number (X) may be predicted differently for each reel 110. The reason why the magazine's loading capacity (C) is determined by the maximum loading capacity (Cmax) is that the predicted number (X) is different each time and the difference between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax) is small, The capacity (Cp) may be calculated to be smaller than the minimum loading capacity (Cmin), and in this case, there is a risk that the number (n) of magazines 130 will continue to increase. Therefore, when the number (n) of magazines 130 exceeds the predetermined number, the processor 11 stops the repetitive process of calculating the expected capacity (Cp) per magazine and sets the loading capacity (C) of the magazine to the maximum loading capacity. (Cmax) or can be determined as a preset value. When the loading capacity (C) of the magazine is determined, the processor 11 may provide information to the material production device and start producing the material 120.

The method of determining the loading capacity of the magazine as described may be written as an algorithm, stored in the storage unit 12, and executed by the processor 11. An algorithm can be implemented as a set of instructions written in program code.

The algorithm according to one implementation calculates the predicted capacity per magazine (Cp) by dividing the predicted number (X) of the material 120 to be produced by the number (n) of magazines 130, and calculates the predicted capacity per magazine (Cp). ) exceeds the maximum loading capacity (Cmax), the process of recalculating the predicted capacity (Cp) per magazine is repeated by increasing the number (n) of magazines 130 one by one, and the predicted capacity (Cp) per magazine is set to the minimum loading capacity. When included between the capacity (Cmin) and the maximum loading capacity (Cmax), the loading capacity of the magazine (C) can be determined as the predicted capacity per magazine (Cp).

When the number (n) of magazines 130 exceeds a predetermined number, the algorithm can determine the loading capacity (C) of the magazine to be equal to the maximum loading capacity (Cmax), and the algorithm determines the predicted number (X) of the magazine ( If it is less than the minimum loading capacity (Cmin) of 130), it may be decided to load all of the materials 120 to be produced into one magazine 130.

The algorithm calculates the predicted number ( You can. Specifically, the algorithm determines the thickness of the preset material 120, the distance between the outermost material of the reel 110 and the reel observation unit 16, and the distance between the reel observation unit 16 and the reel 110. Using the distance, the length of the material 120 wound on the reel 110 can be predicted, and the predicted number (X) can be obtained by dividing the length of the material 120 wound on the reel 110 by the cutting length. there is.

The algorithm created in this way is executed by the processor 11 to determine the loading capacity of the magazine.

FIG. 4 is a diagram illustrating information displayed on the display unit 14 according to one implementation.

The method of determining the loading capacity of the magazine is to use at least one of the maximum loading capacity (Cmax), minimum loading capacity (Cmin), thickness of the material 120, predicted number (X), and loading capacity of the magazine (C). It may further include a display step of displaying to. Since the display unit 14 may include a display, the loading capacity (C) of the magazine determined to the user may be displayed to the user through the display. The user can check the information displayed on the display unit 14, and when producing a different type of material 120 or using a different type of reel 110, the maximum loading capacity (Cmax) that must be entered in the storage unit 12 ), the minimum loading capacity (Cmin), the thickness of the material 120, etc. can be modified.

The display unit 14 shown by way of example in FIG. 4 has a minimum loading capacity (Cmin) of 1,900 pieces, a maximum loading capacity (Cmax) of 1,200 pieces, a thickness of the material 120 of 0.105 mm, and a predicted number (X) of 16,274 pieces. , it indicates that the determined loading capacity (C) of the magazine is 1808 and the number (n) of magazines 130 is 9. The algorithm according to one implementation is that when there are multiple expected capacities (Cp) per magazine included between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax), the number (n) of magazines 130 is the smallest. It was written to determine the expected capacity (Cp) from the loading capacity (C) of the magazine. When the predicted number (X) is 16,274, when the number (n) of magazines 130 is 10, the expected capacity (Cp) per magazine is 1627, and when the number (n) of magazines 130 is 11, The expected capacity (Cp) per magazine is 1479, and even if the number (n) of magazines 130 is 12 or 13, the expected capacity (Cp) per magazine is between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax). It can be a value. The algorithm of one implementation calculates the expected capacity per magazine (Cp) while increasing the magazine 130 by 1, and the calculated expected capacity per magazine (Cp) is between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax). If included, the decision step (S50) is performed, so the magazine's loading capacity (C) is naturally included between the minimum loading capacity (Cmin) and the maximum loading capacity (Cmax) and the number (n) of the magazine 130 is the smallest. can be decided. By minimizing the number (n) of magazines 130 in this way, non-operation of process 2 (P2) depending on the time for replacing the magazine 130 in process 2 (P2) can be minimized.
