[Operation of transport support device]
In explaining this operation, first, the inventory storage place assumed in the present embodiment will be described.

FIG. 2 is a diagram showing an example of such an inventory storage place. As shown in the figure, there are 12 frames W11 to W43 in which steel pieces can be dispersedly placed in the inventory storage area, and each frame has three steel pieces stacked in three stages. Is possible. Then, in the present embodiment, it is assumed that it is necessary to transport three steel pieces of two lots from this inventory storage place. For example, it is assumed that a crane carries three steel pieces of lot A and three steel pieces of lot B from the inventory storage place and loads them on a trolley.

In the figure, the steel pieces of lot A and the steel pieces of lot B are distinguished by different hatching. Specifically, the steel pieces K1 to K3 and K5 to K7 are shown as the steel pieces of Lot A, and the steel pieces K4, K8 and K9 are shown as the steel pieces of Lot B, respectively. The lot A is an example of the first material group, and the steel pieces K1 to K3 and K5 to K7 are examples of the materials belonging to the first material group. Further, lot B is an example of a second material group, and steel pieces K4, K8, and K9 are examples of materials belonging to the second material group.

Further, in the figure, X and Y coordinates are assigned to each of the frames W11 to W43. Specifically, the next numerical value of W in the frames W11 to W43 is assigned to be the X coordinate, and the next numerical value is assigned to be the Y coordinate. Further, in addition to the X and Y coordinates of the frame in which the steel pieces are placed, Z coordinates are also assigned to the stacked steel pieces. Specifically, 1, 2, and 3 are assigned in order from the top row to the bottom row. When the X, Y, and Z coordinates are assigned in this way, the coordinates of the steel piece K8 become (1,1,3) and the coordinates of the steel piece K9 become (3,1,1) as shown in the figure.

On the other hand, the dolly is prepared in front of the frame W31. The X, Y, and Z coordinates are assigned to this bogie in the same way as in the case of steel pieces. When the X, Y, and Z coordinates are assigned in this way, the coordinates of the dolly become (3,0,3) as shown in the figure.

FIG. 3 is a flowchart showing an operation example of the conveyed steel piece determination unit 14 in the present embodiment. Prior to this operation, information that three steel pieces of lot A and three steel pieces of lot B should be conveyed and information about the steel pieces contained in each lot are sent to the transferred steel piece determination unit 14. It shall be given.

As shown in the figure, the transport steel piece determination unit 14 first selects a steel piece in one stage of one frame from the steel pieces that have not been selected so far from the steel pieces of the selection candidates. Is a representative steel piece (step 101). In the example shown in FIG. 2, since the selection candidate steel pieces are the steel pieces of lot A or the steel pieces of lot B, the conveyed steel piece determination unit 14 selects any of the steel pieces K1 to K9.

Next, the transport steel piece determination unit 14 determines one frame from the steel pieces that have not been selected for the representative steel piece among the selection candidate steel pieces for the representative steel piece selected in step 101. A steel piece in one stage is selected and used as the selected steel piece (step 102). Assuming that the steel piece of lot A is selected in step 101, the steel piece of the selection candidate for the representative steel piece is the steel piece of lot B, so that the conveyed steel piece determination unit 14 is any of steel pieces K4, K8, and K9. If the steel piece of lot B is selected in step 101, the steel piece of the selection candidate for the representative steel piece is the steel piece of lot A, so that the conveyed steel piece determination unit 14 is the steel piece K1 to Select any of K3, K5 to K7.

Next, the conveyed steel piece determination unit 14 determines whether or not the combination of the representative steel piece selected in step 101 and the selected steel piece selected in step 102 has been evaluated (step 103).

As a result, if it is determined that this combination has not been evaluated, the conveyed steel piece determination unit 14 calculates the crane load C (step 104). The method of calculating the crane load C will be described later. Then, it is determined whether or not the condition that it is the first time of the loop or that the crane load C is below the minimum value of the crane load at this time is satisfied (step 105). If it is determined that this condition is satisfied, the crane load C updates the minimum crane load value (step 106), and the process proceeds to step 107. That is, in the case of the first time of the loop, since the value is not set for the crane load minimum value at this time, the crane load C calculated this time is set as the crane load minimum value. If the crane load C is lower than the minimum crane load value at this point, the crane load C calculated this time is the minimum value of the crane load calculated so far, so it is set to the minimum crane load value. The value that had been used is replaced with the crane load C calculated this time.

On the other hand, when it is determined in step 103 that this combination has been evaluated, and in step 105, it is the first time of the loop, or the crane load C is below the minimum crane load value at this time. If it is determined that the conditions are not satisfied, the transport steel piece determination unit 14 proceeds to step 107 as it is.

As a result, the conveyed steel piece determination unit 14 determines whether or not all the steel pieces among the selection candidate steel pieces for the representative steel piece selected in step 101 have been selected (step 107). If it is determined that not all the steel pieces have been selected, that is, there is a steel piece that has not been selected, the conveyed steel piece determination unit 14 returns to step 102 to select another steel piece, and steps 103 to 103 to step. Execute 106. If it is determined that all the steel pieces have been selected, the conveyed steel piece determination unit 14 proceeds to step 108.

After that, the conveyed steel piece determination unit 14 determines whether or not all the steel pieces among the steel pieces of the selection candidates have been selected as the representative steel pieces (step 108). If it is determined that not all the steel pieces have been selected as the representative steel piece, that is, there is a steel piece that has not been selected as the representative steel piece, the conveyed steel piece determination unit 14 returns to step 101 and another steel piece. Is selected as the representative steel piece, and steps 102 to 106 are executed. If it is determined that all the steel pieces have been selected as the representative steel pieces, the conveyed steel piece determination unit 14 ends the process.

Here, a method of calculating the crane load C in step 104 will be described. In this embodiment, the crane load C is calculated by the following formula.

In the above calculation formula, Σ means the sum of the steel pieces selected in step 101 and the steel pieces selected in step 102.

Ax is a weight with respect to the amount of movement of the steel piece in the X-axis direction. Further, Pdx is the X coordinate of the trolley, Px is the X coordinate of the steel piece selected in step 101 or the steel piece selected in step 102, and Σ | Pdx-Px | is selected in step 101. It is the amount of movement of the steel piece and the steel piece selected in step 102 in the X-axis direction.

Ay is a weight with respect to the amount of movement of the steel piece in the Y-axis direction. Further, Pdy is the Y coordinate of the carriage, Py is the Y coordinate of the steel piece selected in step 101 or the steel piece selected in step 102, and Σ | Pdy-Py | is selected in step 101. It is the amount of movement of the steel piece and the steel piece selected in step 102 in the Y-axis direction.

Az is a weight with respect to the amount of movement of the steel piece in the Z-axis direction. Further, Pz is the Z coordinate of the steel piece selected in step 101 or the steel piece selected in step 102. However, if there is a steel piece selected in step 102 on the steel piece selected in step 101, "the number of stages of the steel piece selected in step 102" is obtained from the Z coordinate of the steel piece selected in step 101. If there is a steel piece selected in step 101 on the steel piece selected in step 102, the value is obtained by subtracting "+0.5", and from the Z coordinate of the steel piece selected in step 102, "step 101". The value is obtained by subtracting "the number of stages of steel pieces selected in step + 0.5".

In the above calculation formula, Ax × Σ | Pdx-Px | + Ay × Σ | Pdy-Py | is a moving load when moving each material in a substantially horizontal direction, and when moving each material in a substantially horizontal direction. This is an example of a moving load calculated using the moving distance of. Further, Az × ΣPz is an example of a take-out load calculated by using a take-out load when taking out each material in a substantially vertical direction and a moving distance when taking out each material in a substantially vertical direction.

Further, here, the steel pieces are lifted and moved in the substantially vertical direction from the upper side by a crane, but the steel pieces may be taken out and moved in the substantially vertical direction from the lower side. Therefore, the fact that the steel piece selected in step 102 is on the steel piece selected in step 101 is an example of the presence of other materials taken out together with the specific material on the side from which the specific material is taken out. The Z coordinate of the steel piece selected in step 101 is an example of the moving distance when taking out a specific material in the substantially vertical direction, and "the number of steps of the steel piece selected in step 102 + 0.5" is , It is an example of the value according to the amount of other materials. Further, the fact that the steel piece selected in step 101 is on the steel piece selected in step 102 is an example of the existence of another material to be taken out together with the specific material on the side where the specific material is taken out. The Z coordinate of the steel piece selected in step 102 is an example of the moving distance when taking out a specific material in the substantially vertical direction, and "the number of stages of the steel piece selected in step 101 + 0.5" is , It is an example of the value according to the amount of other materials.

In step 104, the conveyed steel piece determination unit 14 acquires the X coordinate Px, Y coordinate Py, and Z coordinate Pz of the steel piece from the steel piece position storage unit 11, and the X coordinate Pdx of the trolley from the trolley position storage unit 12. , Y coordinate Pdy may be acquired, weights Ax, Ay, and Az may be acquired from the parameter storage unit 13, and the minimum value of the crane load may be calculated.

As a result of the transfer steel piece determination unit 14 executing the process of the flowchart of FIG. 3, the minimum value of the crane load C is set as the minimum value of the crane load. Therefore, the transport steel piece determination unit 14 uses the representative steel piece and the selected steel piece corresponding to the minimum crane load value, that is, the representative steel piece and the selected steel piece having the minimum crane load C as the steel piece to be transported. decide.

Next, a case where the processing of the flowchart of FIG. 3 is executed will be described with reference to the example shown in FIG.

FIG. 4 is a diagram showing the coordinates of the steel pieces K1 to K9 stored in the steel piece position storage unit 11 in this case. In the case of the example shown in FIG. 2, the steel piece position storage unit 11 has, for example, (1,1,3) as the coordinates of the steel piece K8 and (3,1,1) as the coordinates of the steel piece K9, respectively. I remember.

FIG. 5 is a diagram showing the coordinates of the bogie stored in the bogie position storage unit 12 in this case. In the case of the example shown in FIG. 2, the dolly position storage unit 12 stores (3,0,3) as the coordinates of the dolly.

FIG. 6 is a diagram showing the values of the weights Ax, Ay, and Az stored in the parameter storage unit 13 in this case. Here, the parameter storage unit 13 stores, for example, "10" as the weight Ax, "10" as the weight Ay, and "100" as the weight Az.

FIG. 7 is a diagram showing an example of the result of executing the process of the flowchart of FIG. 3 in this case.

First, a case where the conveyed steel piece determination unit 14 selects the steel piece K1 as the representative steel piece in step 101 will be described.

In this case, if the conveyed steel piece determination unit 14 selects the steel piece K4 as the selected steel piece in step 102, the crane load C is set to “10 × (| 3-2 | + | 3-1 |” in step 104. ) + 10 × (| 0-3 | + | 0-2 |) + 100 × (1 + 1) ”is calculated to calculate“ 280 ”. Then, since it is determined in step 105 that the loop is the first time, the crane load "280" is used as it is as the minimum crane load value.

Further, if the conveyed steel piece determination unit 14 selects the steel piece K8 as the selected steel piece in step 102, the crane load C is set to “10 × (| 3-2 | + | 3-1 |) in step 104. "470" is calculated by calculating "+10 x (| 0-3 | + | 0-1 |) + 100 x (1 + 3)". Then, since it is determined in step 105 that the calculated crane load C is not smaller than the crane load minimum value "280" at that time, the crane load minimum value is left at "280".

Further, if the conveyed steel piece determination unit 14 selects the steel piece K9 as the selected steel piece in step 102, the crane load C is set to “10 × (| 3-2 | + | 3-3 |) in step 104. "250" is calculated by calculating "+10 x (| 0-3 | + | 0-1 |) + 100 x (1 + 1)". Then, since it is determined in step 105 that the calculated crane load C is smaller than the crane load minimum value "280" at that time, the crane load minimum value is rewritten from "280" to "250".

Next, a case where the conveyed steel piece determination unit 14 selects the steel pieces K2 and K3 as the representative steel pieces in step 101 will be described. In this case, regardless of which steel piece is selected as the selected steel piece in step 102, the transport steel piece determination unit 14 determines that the crane load C calculated in step 104 is the minimum crane load value at that time in step 105. Since it is determined that it is not smaller than "250", the minimum crane load value is left as "250".

Next, a case where the conveyed steel piece determination unit 14 selects the steel piece K4 as the representative steel piece in step 101 will be described.

In this case, if the conveyed steel piece determination unit 14 selects the steel pieces K1, K2, and K3 as the selected steel pieces in step 102, it is determined in step 103 that the combination of the representative steel pieces and the selected steel pieces has been evaluated. Therefore, the minimum crane load is left at "250".

Further, if the conveyed steel piece determination unit 14 selects the steel piece K5 as the selected steel piece in step 102, the crane load C is set to “10 × (| 3-1 | + | 3-1 |) in step 104. "230" is calculated by calculating +10 × (| 0-2 | + | 0-2 |) + 100 × (1 + (2- (1 + 0.5))) ”. Then, since it is determined in step 105 that the calculated crane load C is smaller than the crane load minimum value "250" at that time, the crane load minimum value is rewritten from "250" to "230".

Further, regardless of which of the steel pieces K6 and K7 is selected as the selected steel piece in step 102, the transport steel piece determination unit 14 determines that the crane load C calculated in step 104 is the minimum crane load at that time in step 105. Since it is determined that the value is not smaller than the value, the minimum crane load value is left as "230".

Hereinafter, similarly, even if the case where the conveyed steel piece determination unit 14 selects any of the steel pieces K5 to K9 as the representative steel piece in step 101, the crane load C calculated in step 104 is the crane in step 105. Since it is not determined to be smaller than the minimum load value, the transport steel piece determination unit 14 sets the final minimum crane load value to "230", and sets the representative steel piece K4 and selection corresponding to this minimum crane load value. Let the steel piece K5 be a piece of steel to be conveyed. That is, K4 and K5, which are steel pieces that are close to the position of the bogie and can be taken out together from the same frame and have no steel pieces other than the steel pieces to be transported together, have the smallest crane load C. , The combination of steel pieces to be selected (indicated by a thick line in FIG. 7).

As a result, the determination result output unit 15 outputs the information for specifying the steel piece determined by the conveyed steel piece determination unit 14 to the terminal device 20.
