DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A tire storage system according to an embodiment of the present disclosure will be described below. Fig. 1 is a diagram showing an overview of a tire storage system 1 according to the present embodiment.

[0010] The tire storage system 1 includes a storage unit 2, an RFID reader 50 serving as a tire identification information acquisition means, and a control unit 100. The tire storage system 1 further includes a monitor 300 serving as a display unit.

[0011] The storage section 2 has a plurality of storage spaces capable of accommodating a plurality of tires. In this embodiment, the storage section 2 has a first rack 10 and a second rack 20. The first rack 10 has a first rack lower stage 11 as a first storage space and a first rack upper stage 12 as a second storage space. The second rack 20 has a second rack lower stage 21 as a third storage space and a second rack upper stage 22 as a fourth storage space. In this manner, the storage section 2 has a plurality of storage spaces capable of accommodating tires. In this embodiment, four storage spaces 11, 12, 21, and 22 are shown. Note that the number of storage spaces is not limited to this. For example, it may be ten or more. Note that it is possible to accommodate a plurality of tires in one storage space.

[0012] The tires stored in the storage unit 2 are provided with an RFID tag R as an identification information holding medium. The RFID tag R holds tire identification information. The tire identification information held in the RFID tag R may be any information capable of identifying an individual tire or its type, and may be, for example, a serial number associated with tire information such as the type of tire and tire dimension information. Alternatively, the tire identification information may be information indicating the type of tire.

[0013] The RFID reader 50 as a tire identification information acquiring means acquires tire identification information from an RFID tag R attached to a tire stored in the storage unit 2. The RFID reader 50 is preferably a handheld RFID reader that is provided so as to be able to approach the tire. However, this is not limited thereto. The RFID reader 50 is connected to the control unit 100.

[0014] The control unit 100 performs control for generating storage guide information when storing tires in the storage unit 2. The processing contents by the control unit 100 will be described later.

[0015] The monitor 300 as a display unit displays guide images such as the entrance guide information generated by the control unit 100.

[0016] The storage unit 2 stores tires of various sizes. FIG. 2 is a diagram showing an example of a tire stored in the storage unit 2.

[0017] The storage section 2 stores tires of various sizes, such as tire A, tire B, tire C, tire D, and tire E. For example, tire A has a width dimension W1 and a diameter dimension D1. Tire B has a width dimension W2 and a diameter dimension D2. Tire C has a width dimension W3 and a diameter dimension D3. Tire D has a width dimension W4 and a diameter dimension D4. Tire E has a width dimension W5 and a diameter dimension D5.

[0018] By way of example, the dimensions for the tire mentioned above may be: W1=155mm, D1=520mm, W2=155mm, D2=630mm, W3=205mm, D3=670mm, W4=305mm, D4=670mm, W5=235mm, D5=810mm.

[0019] As shown in Fig. 1, the width dimension of the storage space of the first rack 10 is WR1. The width dimension of the storage space of the second rack 20 is WR2. That is, the width dimension of the first storage space 11 and the second storage space 12 is WR1. In addition, the width dimension of the third storage space 21 and the fourth storage space 22 is WR2.

[0020] As an example, the dimensions of the above-mentioned storage space may be WR1=680 mm, WR2=920 mm.

[0021] In this embodiment, a storage height is set for each of the storage spaces 11, 12, 21, and 22. For example, the storage height of the first storage space 11, the second storage space 12, and the third storage space 21 is 700 mm, and the storage height of the fourth storage space is 850 mm. In this case, the first storage space 11, the second storage space 12, and the third storage space 21 cannot store tires whose diameter exceeds 700 mm. The fourth storage space 22 cannot store tires whose diameter exceeds 850 mm.

[0022] In this embodiment, a load capacity indicating the limit of the weight that can be placed in each of the storage spaces 11, 12, 21, and 22 is set.

[0023] Fig. 3 is a diagram showing an example of tire storage. Fig. 3 shows a state in which a plurality of tires of various sizes shown in Fig. 2 are efficiently arranged and stored in the storage section 2. Specifically, Fig. 3 shows a state in which one tire A, four tires B, two tires C, four tires D, and three tires E are all efficiently arranged and stored in the storage section 2. According to this embodiment, an operator performs storage work based on storage guide information displayed on the monitor 300, which will be described later, and thus, even if there are a plurality of tires of various sizes, the tires can be efficiently stored in this way by using a plurality of storage spaces.

[0024] FIG. 4 is a block diagram of the control unit 100 of the present embodiment.

[0025] As shown in FIG. 4, the control unit 100 has a tire identification information acquisition unit 110, a tire information acquisition unit 120, an entrance guide information generation unit 130, an entrance guide information output unit 140, a tire storage information management unit 150, a tire storage information output unit 160, an exit tire instruction information acquisition unit 170, an exit guide information generation unit 180, an exit guide information output unit 190, and a memory unit 200.

[0026] The tire identification information acquisition unit 110 acquires tire identification information. More specifically, the tire identification information acquisition unit 110 acquires the tire identification information stored in the RFID tag R of the tire that is read by the RFID reader 50.

[0027] The tire information acquisition unit 120 acquires tire information such as tire dimension information based on the acquired tire identification information. The tire dimension information includes tire width dimension information. The tire dimension information may also include tire allowable compression amount information. The tire dimension information may also include tire diameter dimension information. The tire information may also include tire weight information. The tire information may also include wheel mounting information indicating whether or not a wheel is mounted on the tire.

[0028] The tire information acquisition unit 120 acquires tire information such as tire dimension information by, for example, comparing the tire identification information acquired by the tire identification information acquisition unit 110 with a database. The tire identification information may be information capable of identifying an individual tire or a type of tire, and may be, for example, a serial number associated with tire information such as tire dimension information. A database that associates tire identification information such as serial numbers with tire information such as tire dimension information may be stored in the storage unit 200 described later. In this case, the tire information acquisition unit 120 acquires tire information such as tire dimension information based on the tire identification information by comparing the acquired tire identification information such as serial numbers with information in the database. The database may include various information such as tire type information associated with the tire identification information, tire manufacturing date, and wheel mounting information. When a wheel is attached or detached from a tire, the wheel mounting information in the database may be rewritten.

[0029] In addition, tire information such as tire dimension information may be stored in the user memory of the RFID tag as part of the tire identification information. In this case, since the tire identification information includes tire information such as tire dimension information, the tire information acquisition unit 120 can acquire tire information such as tire dimension information based on the tire identification information without performing a comparison operation with information in a database. In addition, various information such as tire type information, tire manufacturing date, and wheel mounting information may be stored in the user memory of the RFID tag R. In addition, when a wheel is attached or detached from a tire, the wheel mounting information in the user memory of the RFID tag R may be rewritten.

[0030] The tire storage guide information generating unit 130 generates tire storage guide information based on tire dimension information based on the acquired tire information. The tire storage guide information generating unit 130 calculates a tire arrangement state that allows the most efficient use of space when storing tires of various sizes in multiple storage spaces, and generates a tire storage guide.

[0031] More specifically, the tire entry guide information generating unit 130 generates tire entry guide information based on the dimensional information of each of the storage spaces 11, 12, 21, and 22, the tire inventory information of each of the storage spaces 11, 12, 21, and 22, and the dimensional information of one or more tires to be stored. Here, the tire inventory information is tire information about tires that have already been stored in the storage unit 2, and includes, for example, the dimensional information of tires that have already been stored in the storage unit 2.

[0032] Here, the tire dimension information includes tire width dimension information. The dimension information of each storage space 11, 12, 21, 22 includes width dimension information of each storage space. For example, the storage guide information generating unit 130 calculates current free space information in each storage space 11, 12, 21, 22 based on the width dimension information of each storage space 11, 12, 21, 22 and the width dimension information of tires already stored in each storage space 11, 12, 21, 22. Then, the storage guide information generating unit 130 generates tire storage guide information indicating in which storage space the tires to be stored should be stored, based on the current free space information in each storage space 11, 12, 21, 22 and the width dimension information of the tires to be stored.

[0033] The tire dimension information may include information on the allowable compression amount of the tire. The storage guide information generating unit 130 generates tire storage guide information indicating which storage space the tires to be stored should be stored in, based on the current free space information in each of the storage spaces 11, 12, 21, and 22 and the allowable compression amount information of the tires to be stored. The storage guide information generating unit 130 may generate tire storage guide information indicating which storage space the tires to be stored should be stored in, based on the current free space information in each of the storage spaces 11, 12, 21, and 22, the allowable compression amount information of the tires to be stored, and the allowable compression amount information of the tires already stored in the storage unit 2. The allowable compression amount information of the tire may be expressed by the allowable value of the width dimension of the tire in a compressed state, or may be expressed by the allowable value of the compression ratio of the tire in a compressed state. Here, the compression ratio is a ratio indicating how much the width dimension of the tire in a compressed state has become smaller than the width dimension of the tire in a normal state.

[0034] The tire dimension information may include tire diameter dimension information. The dimension information of each storage space 11, 12, 21, 22 may include storage height information of each storage space. The storage guide information generating unit 130 may generate tire storage guide information based on the storage height information of each storage space 11, 12, 21, 22 and the diameter dimension information of the tire to be stored.

[0035] The tire information may include tire weight information. For example, the storage guide information generating unit 130 calculates an additional load allowance weight indicating how much more tires can be loaded in each of the storage spaces 11, 12, 21, 22 based on the load capacity information of each of the storage spaces 11, 12, 21, 22 and the weight information of the tires already loaded in each of the storage spaces 11, 12, 21, 22. The storage guide information generating unit 130 may then generate tire storage guide information indicating in which storage space the tires to be stored should be loaded based on the additional load allowance weight in each of the storage spaces 11, 12, 21, 22 and the weight information of the tires to be stored.

[0036] The entrance guide information output unit 140 outputs the entrance guide information generated by the entrance guide information generating unit 130 to the monitor 300.

[0037] The tire storage information management unit 150 manages information indicating the storage state of tires. For example, the tire storage information management unit 150 generates tire storage information including information indicating the compression state of tires based on information indicating the compression state of stored tires and tire storage period information.

[0038] The tire storage information output unit 160 outputs the tire storage information generated by the tire storage information management unit 150 to the monitor 300 in response to a request from an operator or the like.

[0039] The outgoing tire instruction information acquisition unit 170 acquires instruction information for tires to be shipped out. For example, outgoing tire instruction information, which is information indicating the type of tires to be shipped out, input by an operator, is acquired.

[0040] The outgoing guide information generating unit 180 identifies a storage space in which the tires to be outgoing are stored from among a plurality of storage spaces based on the outgoing tire instruction information, and generates outgoing guide information for the tires to be outgoing.

[0041] The leaving guide information output unit 190 outputs the leaving guide information generated by the leaving guide information generating unit 180 to the monitor 300.

[0042] The storage unit 200 stores various types of information. For example, a database that associates tire identification information with tire information such as tire dimension information is stored. The storage unit 200 also stores dimension information of each storage space and tire inventory information of each storage space. The tire inventory information of each storage space is rewritten every time a tire is stored or removed. The storage unit 200 also stores information managed by the tire storage information management unit 150 while updating it as necessary.

[0043] 5A to 16 are diagrams for explaining examples of tire storage and unstorage operations performed by the tire storage system 1 of this embodiment.

[0044] 5A and 5B are diagrams for explaining a first example of the storage operation. As shown in Fig. 5A, a plurality of tires are already stored in each storage space of the storage unit 2. In this state, a case where a tire D is brought in to be stored in the storage unit 2 will be considered.

[0045] The operator acquires tire identification information of the tire that has been brought in using the RFID reader 50. The control unit 100 acquires the type of the tire that has been brought in and its dimensional information, etc., based on the acquired tire identification information. In this example, the control unit 100 determines that the tire that has been brought in is tire D (width dimension W4=305 mm).

[0046] The control unit 100 calculates current free space information in each of the storage spaces 11, 12, 21, 22 based on the width dimension information of each of the storage spaces 11, 12, 21, 22 and the tire inventory information of each of the storage spaces 11, 12, 21, 22, i.e., the width dimension information of tires already stored in each of the storage spaces 11, 12, 21, 22. In this example, the control unit 100 determines that there is almost no free space in the first storage space 11, the second storage space 12, and the fourth storage space 22 based on the calculation result of the free space information. On the other hand, the control unit 100 determines that the third storage space 21 (width dimension WR2=920 mm) contains two tires D (width dimension W4=305 mm), but has a free space (310 mm) large enough to store one tire D (width dimension W4=305 mm).

[0047] Therefore, the control unit 100 determines that the brought-in tire D can be stored in the third storage space 21, and generates storage guide information. The display unit 300 displays storage guide information instructing the operator to store the brought-in tire D in the third storage space 21 (second rack lower level 21) as shown in Fig. 5B.

[0048] The available space information may be calculated at the timing of past tire entry and exit, and the calculated information may be stored in the storage unit 200.

[0049] 6A and 6B are diagrams for explaining a second example of the storage operation. As shown in Fig. 6A, a plurality of tires are already stored in each storage space of the storage unit 2. In this state, a case will be considered in which a plurality of tires, here tires A and D, are brought in to be stored in the storage unit 2.

[0050] The operator uses the RFID reader 50 to acquire tire identification information of the multiple tires that have been brought in. The control unit 100 acquires the type and dimension information of each of the multiple tires that have been brought in based on the acquired tire identification information. In this example, the control unit 100 determines that the tires that have been brought in are tire A (W1=155 mm) and tire D (width dimension W4=305 mm). At this time, the control unit 100 may recognize the number of tires that are being stocked at the same time based on the number of pieces of tire identification information acquired consecutively.

[0051] Based on the width dimension information of each storage space and the calculation result of the free space based on the tire inventory information of each storage space, the control unit 100 determines that there is almost no free space in the first storage space 11 and the fourth storage space 22. On the other hand, the control unit 100 determines that the second storage space 12 (width dimension WR1 = 680 mm) contains three tires B (width dimension W2 = 155 mm) but has free space (215 mm). The control unit 100 also determines that the third storage space 21 (width dimension WR2 = 920 mm) contains two tires D (width dimension W4 = 305 mm) but has free space (310 mm).

[0052] Based on information on the free space in these storage spaces and information on the width dimensions of the brought-in tires, the control unit 100 judges whether the brought-in tires can be stored in the storage unit 2. In this example, the control unit 100 judges that the second storage space 12 has a free space (215 mm) large enough to accommodate one tire A (width dimension W1 = 155 mm), and the third storage space 21 has a free space (310 mm) large enough to accommodate one tire D (width dimension W4 = 305 mm).

[0053] Therefore, the control unit 100 determines that the multiple tires (tire A, tire D) that have been brought in can be received in the storage unit 2, and generates storage guide information. The display unit 300 displays storage guide information that instructs the operator to store tire A in the second storage space 12 (upper level 12 of the first rack) and tire D in the third storage space 21 (lower level 21 of the second rack), as shown in Fig. 6B.

[0054] In this manner, tire identification information of multiple tires of different sizes that are stored simultaneously is acquired by the RFID reader 50. The control unit 100 acquires tire dimension information of multiple tires of different sizes that are stored simultaneously based on the tire identification information. Then, the control unit 100 generates tire storage guide information for storing multiple tires of different sizes simultaneously.

[0055] 7A to 7C are diagrams for explaining a third example of the storage operation. As shown in Fig. 7A, a plurality of tires are already stored in each storage space of the storage unit 2. In this state, a case will be considered in which a tire D is brought in to be stored in the storage unit 2.

[0056] The operator acquires tire identification information of the brought-in tire using the RFID reader 50. The control unit 100 acquires the type of the brought-in tire and its dimensional information, etc. based on the acquired tire identification information. In this example, the control unit 100 determines that the brought-in tire is tire D (width dimension W4=305 mm, allowable compression rate CR=5%).

[0057] Based on the width dimension information of each storage space and the calculation result of the free space based on the tire inventory information of each storage space, the control unit 100 determines that there is almost no free space in the second storage space 12, the third storage space 21, and the fourth storage space 22. On the other hand, the control unit 100 determines that the first storage space 11 (width dimension WR1 = 680 mm) contains two tires C (width dimension W3 = 205 mm, allowable compression rate CR = 5%), but there is free space (270 mm).

[0058] The control unit 100 determines that the first storage space 11 has the largest free space among the multiple storage spaces 11, 12, 21, and 22. However, the control unit 100 determines that the free space (270 mm) of the first storage space 11 cannot accommodate the tire D (width dimension W4=305 mm) as it is.

[0059] Here, the control unit 100 also acquires allowable compression amount information of the brought-in tire based on the acquired tire identification information. In addition, the control unit 100 also stores allowable compression amount information of tires that have already been stored in the storage unit 2 as tire inventory information.

[0060] FIG. 7C is a diagram for explaining the allowable compression amount information of a tire. As shown in the left diagram of FIG. 7C, when a wheel rim is attached, it is difficult to compress the tire in the width direction of the tire so that the width dimension Wa becomes smaller. On the other hand, as shown in the right diagram of FIG. 7C, when a wheel rim is not attached, it is possible to compress the tire in the width direction so that the width dimension Wa becomes the width dimension Wb. Here, the allowable compression amount information of a tire may be expressed by the width dimension Wb itself of the tire in the compressed state, or may be expressed by the compression ratio of the tire in the compressed state. The compression ratio of the tire in the compressed state, that is, the allowable compression ratio CR, is a ratio indicating how small the allowable width dimension Wb of the tire in the compressed state is relative to the width dimension Wa of the tire in the normal state, and is expressed as the allowable compression ratio CR=(Wa-Wb) / Wa. Note that the allowable compression ratio CR of a tire in the state where a rim is not attached is set to a value greater than 0%, and the value of the allowable compression ratio CR is stored, for example, in the storage unit 200. Then, this allowable compression ratio CR is used in calculations for arranging the tire according to the situation such as the available space. The allowable compression rate CR may be set for each type of tire. On the other hand, the allowable compression rate of a tire with a rim mounted is set to 0%. That is, in the case of a tire with a rim mounted, the tire width dimension Wa is assumed to be uncompressed and is used in calculations for arranging the tire. The storage guide information generating unit 130 determines candidates for tire placement positions in the storage space based on tire dimension information including tire width dimension information and tire allowable compression information, and generates tire storage guide information.

[0061] The control unit 100 generates storage guide information in a case where the one tire D brought in and the two tires C already stored in the storage unit 2 can be received in the storage unit 2 if they are all compressed at a compression rate equal to or lower than the allowable compression rate CR. In this example, it is assumed that the allowable compression rate CR of both the brought in tire D and the tire C already stored in the storage unit 2 is 5%. The control unit 100 determines that the one tire D brought in and the two tires C already stored in the storage unit 2 can be received in the storage unit 2 if they are all compressed at a compression rate of 5%, and generates storage guide information.

[0062] The display unit 300 displays storage guide information instructing the operator to store the brought-in tire D in the first storage space 11 (lower level 11 of the first rack) as shown in Fig. 7B. In this manner, the control unit 100 may generate storage guide information based on tire inventory information, i.e., allowable compression amount information of tires already stored in the storage unit 2, in addition to allowable compression amount information of the tire to be stored. Note that it is preferable to include information indicating that the tire needs to be compressed before storage in the storage guide information.

[0063] If there are multiple storage spaces in which tires can be stored if they are compressed, the control unit 100 selects the storage space in which the tire compression rate is minimized as the storage space for storing the brought-in tire.

[0064] 8A and 8B are diagrams for explaining a fourth example of the storage operation. As shown in Fig. 8A, a plurality of tires are already stored in each storage space of the storage unit 2. In this state, a case where a tire D is brought in to be stored in the storage unit 2 will be considered.

[0065] The operator acquires tire identification information of the tire that has been brought in using the RFID reader 50. The control unit 100 acquires the type of the tire that has been brought in and its dimensional information, etc., based on the acquired tire identification information. In this example, the control unit 100 determines that the tire that has been brought in is tire D (width dimension W4=305 mm).

[0066] Based on the width dimension information of each storage space and the calculation result of the free space based on the tire inventory information of each storage space, the control unit 100 determines that there is almost no free space in the first storage space 11, the second storage space 12, and the third storage space 21. On the other hand, the control unit 100 determines that although three tires E (width dimension W5 = 235 mm) are stored in the fourth storage space 22 (width dimension WR2 = 920 mm), there is free space (215 mm).

[0067] The control unit 100 determines that the fourth storage space 22 has the largest free space among the multiple storage spaces 11, 12, 21, and 22. However, the control unit 100 determines that tire D (width dimension W4=305 mm) cannot be accommodated in the free space (215 mm) of the fourth storage space 22 as it is. Therefore, the control unit 100 further determines whether all tires, including the tire that has been brought in, can be accommodated in the storage unit 2 by changing the storage position of the tires that have already been stored, that is, by performing a rearrangement operation of the stock tires.

[0068] In this example, the control unit 100 determines that one tire B (W=155 mm) stored in the third storage space 21 as an already-stored tire can be moved to the free space (215 mm) of the fourth storage space 22. Then, although two tires D (width W4=305 mm) remain in the third storage space 21 (width WR2=920 mm), it determines that a free space (310 mm) can be created to store one more tire D (width W4=305 mm).

[0069] Therefore, the control unit 100 determines that the brought-in tire D can also be stored by changing the storage position of the stored tires, and generates storage guide information. The display unit 300 displays storage guide information as shown in Fig. 8B, which instructs the operator to move the storage position of the stored tire B from the third storage space 21 (lower level 21 of the second rack) to the fourth storage space 22 (upper level 22 of the second rack) and to store the brought-in tire D in the third storage space 21 (lower level 21 of the second rack). It is preferable that information regarding the order of work to be performed by the operator is included in the storage guide information.

[0070] 9A and 9B are diagrams for explaining a fifth example of the storage operation. As shown in Fig. 9A, a plurality of tires are already stored in each storage space of the storage unit 2. Consider the case where a tire D is brought in to be stored in the storage unit 2 in this state.

[0071] The operator acquires tire identification information of the tire that has been brought in using the RFID reader 50. The control unit 100 acquires the type of the tire that has been brought in and its dimensional information, etc., based on the acquired tire identification information. In this example, the control unit 100 determines that the tire that has been brought in is tire D (width dimension W4=305 mm).

[0072] Based on the width dimension information of each storage space and the calculation result of the free space based on the tire inventory information of each storage space, the control unit 100 determines that there is almost no free space in the first storage space 11, the third storage space 21, and the fourth storage space 22. On the other hand, the control unit 100 determines that although three tires B (width dimension W5 = 155 mm) are stored in the second storage space 12 (width dimension WR1 = 680 mm), there is free space (215 mm).

[0073] The control unit 100 determines that the second storage space 12 has the largest free space among the multiple storage spaces 11, 12, 21, and 22. However, the control unit 100 determines that the free space (215 mm) of the second storage space 12 cannot accommodate the tire D (width dimension W4=305 mm) as it is. Therefore, the control unit 100 further determines whether all the tires, including the tire that has been brought in, can be accommodated in the storage unit 2 by changing the storage position of the tires that have already been stored, that is, by performing a rearrangement operation of the stock tires.

[0074] In this example, the control unit 100 determines that one tire A (W=155 mm) stored in the first storage space 11 as an already-stored tire can be moved to the free space (215 mm) of the second storage space 12. Then, it determines that a free space (270 mm) can be created, although two tires C (width W4=205 mm) remain in the first storage space 11 (width WR1=680 mm).

[0075] In this example, the control unit 100 judges that the tire D (width W4=305 mm) cannot be accommodated in the free space (270 mm) of the first storage space 11 as it is.

[0076] However, as described in the third example of the storage operation, the control unit 100 determines that the tire D that has been brought in and the two tires C that have already been stored in the storage unit 2 can be received in the storage unit 2 if they are all compressed to the allowable compression rate CR, and generates storage guide information. The display unit 300 displays storage guide information that instructs the operator to move the storage position of the stored tire A from the first storage space 11 (lower level of the first rack 11) to the second storage space 12 (upper level of the first rack 12) and to store the carried-in tire D in the first storage space 11 (lower level of the first rack 11), as shown in FIG. 9B. At this time, it is preferable to include in the storage guide information information indicating that the tire needs to be compressed before being stored when the carried-in tire D is stored in the first storage space 11 (lower level of the first rack 11).

[0077] 10A to 10C are diagrams for explaining a sixth example of the storage operation. As shown in Fig. 10A, a plurality of tires are already stored in each storage space of the storage unit 2. In this state, a case will be considered in which a tire E is brought in to be stored in the storage unit 2.

[0078] The operator acquires tire identification information of the tire that has been brought in using the RFID reader 50. The control unit 100 acquires the type of the tire that has been brought in and its dimensional information, etc., based on the acquired tire identification information. In this example, the control unit 100 determines that the tire that has been brought in is tire E (diameter dimension D5=810 mm, width dimension W5=235 mm).

[0079] The control unit 100 determines that there is almost no free space in the first storage space 11 and the fourth storage space 22 based on the width dimension information of each storage space and the calculation result of the free space based on the tire inventory information of each storage space. On the other hand, the control unit 100 determines that there is a free space (215 mm) in the second storage space 12 (width dimension WR1 = 680 mm), even though two tires B (width dimension W2 = 155 mm) and one tire A (width dimension W1 = 155 mm) are stored therein. Also, the control unit 100 determines that there is a free space (310 mm) in the third storage space 21 (width dimension WR2 = 920 mm), even though two tires D (width dimension W4 = 305 mm) are stored therein.

[0080] The control unit 100 also stores information on the storage height of each storage space as the dimensional information of each storage space 11, 12, 21, 22. For example, the storage height of the first storage space 11, the second storage space 12, and the third storage space 21 is 700 mm or less, and the storage height of the fourth storage space is 850 mm or less. Therefore, the control unit 100 determines that the tire E (diameter dimension D5 = 810 mm) cannot be stored in the first storage space 11, the second storage space 12, and the third storage space 21 (storage height = 700 mm).

[0081] The control unit 100 judges whether or not the tire B already stored in the first storage space 11 can be moved to another storage space. In this example, the control unit 100 judges that one tire B (width dimension W2=155 mm) stored in the fourth storage space 22 as an already-stored tire can be moved to the empty space (310 mm) of the third storage space 21 or the empty space (215 mm) of the second storage space 12.

[0082] As a result, two tires E (width dimension W5 = 235 mm) and one tire B (width dimension W2 = 155 mm) will remain in the fourth storage space 22 (width dimension WR2 = 920 mm), but it is determined that an empty space (295 mm) can be created to accommodate one more tire E (width dimension W5 = 235 mm).

[0083] Therefore, the control unit 100 determines that the brought-in tire D can also be stored by changing the storage position of the stored tires, and generates storage guide information.

[0084] FIG. 10B is an example in which the control unit 100 generates storage guide information under conditions that reduce the burden of moving stored tires. In this case, the display unit 300 displays storage guide information that instructs the operator to move the storage position of stored tire B from the fourth storage space 22 (second rack upper level 22) to the third storage space 21 (second rack lower level 21) and to store the carried-in tire E in the fourth storage space 22 (second rack upper level 22). This makes it easier to rearrange the tire positions of stored tires. The conditions that reduce the burden of moving stored tires are determined by taking into consideration the number of stored tires to be rearranged and the amount of movement.

[0085] 10C is an example in which the control unit 100 generates storage guide information under conditions that reduce dead space. In this case, the display unit 300 displays storage guide information that instructs the operator to move the storage position of the stored tire B from the fourth storage space 22 (second rack upper level 22) to the second storage space 12 (first rack upper level 12) and to store the carried-in tire E in the fourth storage space 22 (second rack upper level 22). This increases the possibility that additional tires can be stored without changing the tire positions of the stored tires when they are carried in.

[0086] It is preferable that the above-mentioned conditions to be prioritized in generating the storage guide information can be selected by the operator.

[0087] 11A and 11B are diagrams for explaining a seventh example of the storage operation. As shown in Fig. 11A, a plurality of tires are already stored in each storage space of the storage unit 2. In this state, a case where a tire B is brought in to be stored in the storage unit 2 will be considered.

[0088] The operator uses the RFID reader 50 to obtain tire identification information of the tire that has been brought in. The control unit 100 obtains the type of the tire that has been brought in and its dimensional information, etc., based on the obtained tire identification information. In this example, the control unit 100 determines that the tire that has been brought in is tire B (width dimension W2=155 mm). The control unit 100 also obtains weight information of the tire B that has been brought in based on the obtained tire identification information. The control unit 100 stores load capacity information for each of the storage spaces 11, 12, 21, and 22.

[0089] Based on the width dimension information of each storage space and the calculation result of the free space based on the tire inventory information of each storage space, the control unit 100 determines that there is almost no free space in the first storage space 11, the third storage space 21, and the fourth storage space 22. On the other hand, the control unit 100 determines that although three tires B (width dimension W2 = 155 mm) are stored in the second storage space 12 (width dimension WR1 = 680 mm), there is free space (215 mm).

[0090] The control unit 100 calculates the additional load allowance weight indicating how much more tires can be loaded in each of the storage spaces 11, 12, 21, 22 based on the load capacity information of each of the storage spaces 11, 12, 21, 22 and the weight information of the tires already stored in each of the storage spaces 11, 12, 21, 22. Then, the storage guide information generating unit 130 generates tire storage guide information indicating in which storage space the tires to be stored should be stored based on the additional load allowance weight in each of the storage spaces 11, 12, 21, 22 and the weight information of the tires to be stored. For example, the control unit 100 compares the weight information of tire B with the additional load allowance weight of the second storage space 12 and determines that if tire B is additionally stored in the second storage space 12, the load capacity will be exceeded. In this case, the control unit 100 moves a tire (tire A) that is lighter than tire B to the second storage space 12, and determines whether or not the space vacated by the movement can be used to move the carried-in tire B.

[0091] In this example, the control unit 100 determines that one tire A (width dimension W2=155 mm) stored in the fourth storage space 22 as an already-stored tire can be moved to the empty space (215 mm) of the second storage space 12. In other words, the control unit 100 determines that storing three tires B and one tire A in the second storage space 12 will not exceed the load capacity of the second storage space 12.

[0092] The control unit 100 determines that if the one tire A stored in the fourth storage space 22 is moved to the empty space in the second storage space 12, three tires E (width dimension W5 = 235 mm) will remain in the fourth storage space 22 (width dimension WR2 = 920 mm), but empty space (215 mm) can be created to store one more tire B (width dimension W2 = 155 mm).

[0093] Therefore, the control unit 100 determines that the tire B that has been brought in can also be stored by changing the storage position of the stored tire, and generates storage guide information. The display unit 300 displays storage guide information that instructs the operator to move the storage position of the stored tire A from the fourth storage space 22 (second rack upper stage 22) to the second storage space 12 (first rack upper stage 12) and to store the carried tire B in the fourth storage space 22 (second rack upper stage 22), as shown in FIG. 11B. At this time, it is preferable that the storage guide information includes warning information regarding whether or not the tire can be stored. The carried tire B can be stored in the storage space 12 in terms of size. Therefore, it is preferable that the storage guide information includes information indicating that storing the tire B in the second storage space 12 will exceed the load capacity of the storage space.

[0094] 12A and 12B are diagrams for explaining an eighth example of the storage operation. As shown in Fig. 12A, a plurality of tires are already stored in each storage space of the storage unit 2. In this state, a case where a tire D is brought in to be stored in the storage unit 2 will be considered.

[0095] The operator acquires tire identification information of the tire that has been brought in using the RFID reader 50. The control unit 100 acquires the type of the tire that has been brought in and its dimensional information, etc., based on the acquired tire identification information. In this example, the control unit 100 determines that the tire that has been brought in is tire D (width dimension W4=305 mm).

[0096] Based on the width dimension information of each storage space and the calculation result of the free space based on the tire inventory information of each storage space, the control unit 100 determines that there is almost no free space in the second storage space 12, the third storage space 21, and the fourth storage space 22. Furthermore, the control unit 100 determines that even in the first storage space 11 (width dimension WR1 = 680 mm) which has the widest free space, one tire C (width dimension W3 = 205 mm) and one tire D (width dimension W2 = 305 mm) are stored therein, so that the free space (170 mm) is not sufficient to store tire D.

[0097] In this case, the control unit 100 generates information indicating that entry is impossible as the entry guide information. The display unit 300 displays information for notifying the operator that entry is impossible, as shown in Fig. 12B.

[0098] 13A and 13B are diagrams for explaining a ninth example of a warehousing operation. As shown in FIG. 13A, a plurality of tires are already stored in each storage space of the storage unit 2. In this state, a case will be considered in which a tire Dh, which is a tire D with a wheel attached, is carried in to be stored in the storage unit 2. Here, as described above, it is difficult to compress a tire with a wheel rim attached in the width direction of the tire so as to reduce the width dimension.

[0099] The operator acquires tire identification information of the tire that has been brought in using the RFID reader 50. The control unit 100 acquires the type of the tire that has been brought in and its dimensional information, etc., based on the acquired tire identification information. In this example, the control unit 100 determines that the tire that has been brought in is a tire Dh (width dimension W4=305 mm) with a wheel.

[0100] Based on the width dimension information of each storage space and the calculation result of the free space based on the tire inventory information of each storage space, the control unit 100 determines that there is almost no free space in the second storage space 12, the third storage space 21, and the fourth storage space 22. Furthermore, the control unit 100 determines that even in the first storage space 11 (width dimension WR1 = 680 mm) which has the widest free space, the free space (270 mm) is insufficient to store the tire Dh with wheels because two tires Ch (width dimension W3 = 205 mm), which are tire C with wheels attached, are stored therein.

[0101] In this case, the control unit 100 generates information indicating that entry is impossible as the entry guide information. The display unit 300 displays information for notifying the operator that entry is impossible, as shown in Fig. 13B.

[0102] FIG. 14 shows an example of tire storage information displayed on the monitor 300.

[0103] The control unit 100 generates tire storage information including information indicating the compression state of the tire based on information indicating the compression state of the stored tire and tire storage period information. Then, the control unit 100 outputs the tire storage information including information indicating the compression state of the tire to the monitor 300 in response to an external request or the like.

[0104] For example, if any tire is stored in a compressed state among the tires stored in the storage unit 2, the control unit 100 outputs tire storage information including information indicating the tire compression state to the monitor 300 when the compressed state has continued for a predetermined time. Alternatively, in response to an inquiry operation by an operator, the control unit 100 outputs tire storage information including information indicating the tire compression state to the monitor 300.

[0105] The information indicating the compression state of the tire can be calculated based on the width dimension information of each storage space and the width dimension information of the tires stored in each storage space. Here, the information indicating the compression state of the tire may be the compression rate of the tire.

[0106] As shown in the display example of Fig. 14, the tire storage information may include information indicating the location of the storage space in which the compressed tires are stored. Also, the tire storage information may include information on the elapsed time during which the compressed state is maintained.

[0107] It may not be desirable to store tires in a compressed state for a long period of time. With the configuration of this embodiment, the condition of the tires stored in the storage unit 2 can be appropriately managed.

[0108] FIG. 15 is an example of the leaving guide information displayed on the monitor 300.

[0109] The control unit 100 identifies, from among a plurality of storage spaces, a storage space in which the tires to be outputted are stored, based on the output tire instruction information, and generates output guide information for the tires to be outputted.

[0110] For example, when an input instructing to take out tire C is input to an input unit (not shown) connected to the control unit 100, the control unit 100 identifies the storage space in which tire C is stored and generates take-out guide information for tire C. Then, the control unit 100 outputs the generated take-out guide information to the monitor 300.

[0111] 15, the delivery guide information includes information indicating the location of the storage space for the tire that has been instructed to be delivered. The delivery guide information may include various types of notification information, such as information on the number of tires in stock that have been instructed to be delivered, information indicating that the tires are stored in a compressed state, and information indicating that other types of tires are also stored in the same storage space.

[0112] This allows the operator to efficiently remove tires from the warehouse, since the storage space in which to search for the tires to be removed is identified even if multiple different types of tires are stored in multiple storage spaces.

[0113] Fig. 16 is a diagram for explaining a tenth example of storage work. As shown in Fig. 16, there is no limit to the number of tires stored in the storage unit 2 at one time, and it may be, for example, about 10 to 30. Furthermore, the number of storage spaces may be even greater.

[0114] In such a case, the RFID reader 50 acquires tire identification information of multiple tires of different sizes that are stored at the same time. The control unit 100 acquires tire dimension information of multiple tires of different sizes that are stored at the same time based on the tire identification information. Then, the control unit 100 generates tire storage guide information for storing multiple tires of different sizes at the same time.

[0115] For example, the control unit 100 calculates free space information for each storage space based on the dimension information for each storage space and tire inventory information for each storage space, and generates tire storage guide information indicating which tire to be stored should be stored in which storage space based on the calculated free space information for each storage space and width dimension information for multiple tires of different sizes stored at the same time. In this way, the control unit 100 can generate tire storage guide information based on tire information such as tire dimension information based on tire identification information. The control unit 100 may further generate tire storage guide information using various information related to tires and storage spaces described above.

[0116] FIG. 17 is a diagram showing a modified example of the tire storage system 1. In FIG.

[0117] In this modification, the tire storage system 1 includes a printer 400 connected to the control unit 100.

[0118] When the RFID reader 50 acquires tire information from the RFID tag R attached to the tire to be stored in the storage unit 2, the printer 400 outputs a printed matter M, such as a sticker or paper on which the tire information is printed, which serves as a marker. The printed tire information preferably includes information indicating the type of tire, such as "Tire D." Note that the printed matter M may also have information printed thereon indicating the location of the storage space in which the tire to be stored should be stored. The information on the location of the storage space may be textual information, such as "lower level of the second rack," or may be illustrated information.

[0119] When a tire is brought into storage, the operator attaches this printed matter M to the tire to be stored. In this way, when the tire is to be removed from storage, the operator can specify the storage space in which to look for the tire to be removed based on the removal guide information shown in Fig. 15, and then visually check the printed matter M attached to the tire, thereby enabling the tire to be removed more efficiently.

[0120] When changing tires in stock, the printer 400 may print out a printed matter M on which tire information and new storage space information are printed. The operator attaches the newly printed matter M to the tire to be changed.

[0121] FIG. 18 is a flowchart showing the flow of main processes in the tire storage system 1 of this embodiment.

[0122] In step S11, the RFID reader 50 serving as a tire identification information acquiring means acquires the tire identification information of the tire to be stored in the storage unit 2.

[0123] In step S12, the control unit 100 generates tire storage guide information based on tire dimension information based on the acquired tire identification information.

[0124] FIG. 19 is a flowchart showing the details of the process flow of the tire storage system 1 of this embodiment.

[0125] In step S21, the RFID reader 50 as a tire identification information acquiring means acquires tire identification information of tires to be stored in the storage unit 2. The process of step S21 corresponds to the tire identification information acquiring process of step S11 in the flowchart of Fig. 18. At this time, the control unit 100 may recognize the number of tires to be stored at the same time based on the number of pieces of tire identification information acquired consecutively.

[0126] In step S22, the control unit 100 acquires tire information such as tire dimension information based on the tire identification information. In this embodiment, the tire dimension information includes tire width dimension information and tire allowable compression amount information.

[0127] In step S23, the control unit 100 calculates free space information for each storage space based on the width dimension information for each storage space and the tire inventory information for each storage space. This step may be performed when updating the tire inventory information at the previous tire entry / exit.

[0128] In step S24, the control unit 100 performs a tire storage guide information generating process for generating tire storage guide information based on the calculated free space information in each storage space and width dimension information of the tires to be stored.

[0129] In step S25, the control unit 100 outputs the generated tire entrance guide information to the monitor 300. The monitor 300 displays the generated tire entrance guide information.

[0130] In step S26, the control unit 100 updates the tire inventory information. If the tire is stored in a compressed state, the control unit 100 updates the tire inventory information including the information on the compression rate of the tire.

[0131] FIG. 20 is a flowchart showing an example of a tire storage guide information generating process in the processing of the tire storage system 1 of this embodiment.

[0132] In step S31, the control unit 100 determines whether or not the tires can be stored without changing the positions of the stock tires based on the dimensional information of the tires to be stored. More specifically, the control unit 100 determines whether or not the new tires to be stored can be stored without changing the storage positions of the tires already stored based on the dimensional information of the tires based on the acquired tire identification information, the dimensional information of each storage space, and the tire inventory information in each storage space. At this point, it is determined whether or not the tires can be stored without compressing them.

[0133] In step S31, if the control unit 100 determines that the tires can be stored without changing the positions of the stock tires, the process proceeds to step S32.

[0134] On the other hand, in step S31, if the control unit 100 determines that the tires cannot be stored without changing the positions of the stock tires, the process proceeds to step S .

[0135] In step S34, the control unit 100 judges whether the tire can be stored if it is compressed. More specifically, the control unit 100 judges whether the new tire can be stored without changing the storage position of the tire already stored, based on the allowable compression amount information of the tire based on the acquired tire identification information, the dimension information of each storage space, and the tire inventory information in each storage space. Note that the tire inventory information may include the allowable compression amount information of the tires already stored in the storage unit 2.

[0136] In step S34, if the control unit 100 determines that the tire can be stored if it is compressed, the process proceeds to step S35.

[0137] In step S35, if there are multiple storage spaces in which the tire can be stored if it is compressed, the control unit 100 determines the storage space that will result in the smallest compression rate of the tire. The control unit 100 determines the storage space that will result in the smallest compression rate of the tire as the storage space in which to store the tire, and proceeds to step S32.

[0138] In step S34, if the control unit 100 determines that the tire cannot be stored even if the tire is compressed, the process proceeds to step S36.

[0139] In step S36, the control unit 100 judges whether the tire can be stored by rearranging the positions of the stock tires. At this point, it is judged whether the tire can be stored without compressing the tire.

[0140] In step S36, if the control unit 100 determines that the tires can be stored by rearranging the positions of the stock tires, the process proceeds to step S37.

[0141] In step S37, the control unit 100 determines an appropriate tire movement procedure. For example, the control unit 100 determines a movement procedure that reduces the burden of moving stock tires, and proceeds to step S32. Alternatively, the control unit 100 determines a movement procedure that reduces dead space in the storage space, and proceeds to step S32. In this way, when the control unit 100 determines that it is necessary to change the storage position of the stored tires to make it possible to store newly stored tires, it generates tire storage guide information including an instruction to change the storage position of the stored tires.

[0142] In step S36, if the control unit 100 determines that the tires cannot be stored even if the positions of the stock tires are rearranged, the process proceeds to step S38.

[0143] In step S38, the control unit 100 determines whether the tire can be stored if the positions of the stock tires are rearranged and the tire is compressed.

[0144] In step S38, if the control unit 100 determines that the tires can be stored by rearranging the positions of the stock tires and compressing the tires, the process proceeds to step S37 and determines an appropriate movement procedure.

[0145] In step S38, if the control unit 100 determines that the tire cannot be stored even after rearranging the positions of the stock tires and compressing the tire, the control unit 100 proceeds to step S39 and determines that the tire cannot be stored. In this case, information for notifying that the tire cannot be stored is output.

[0146] In step S32, the control unit 100 determines whether or not there is a problem with the load-bearing capacity of the storage space in which the tires are stored, based on the weight information of the tires to be stored.

[0147] In step S32, if the control unit 100 determines that there is a problem with the load-bearing capacity of the storage space, the process proceeds to step S36, where it determines whether or not the tires can be stored by rearranging the positions of the stock tires.

[0148] In step S32, when the control unit 100 determines that there is no problem with the load-bearing capacity of the storage space, the process proceeds to step S33, and generates tire storage guide information.

[0149] With the above-described configuration, even when storing tires of various sizes in multiple storage spaces, the tires can be stored by efficiently utilizing the space while taking into consideration the tire dimensions, etc.

[0150] The tire information acquisition means is not limited to an RFID reader. For example, the tire identification information acquisition unit 110 may acquire information manually input by a user as the tire identification information. In this case, for example, the user inputs information for identifying the tire to an input unit (not shown) connected to the control unit 100. The tire identification information acquisition unit 110 acquires the input information as the tire identification information. The tire identification information acquisition unit 110 may also acquire information acquired by an optical reading means as the tire identification information. For example, the tire identification information acquisition unit 110 may acquire image information of the tire captured by a camera of a mobile terminal such as a smartphone or a tablet as the tire identification information.
