Description

  The present invention relates to a production command issued from a molding line to a bead member production apparatus for producing a bead member to be supplied to a molding line having a plurality of molding machines. The present invention relates to a bead member production command method in a tire molding system including a plurality of bead member production apparatuses that supply bead members to a line.

In the tire molding process, members such as carcass ply, bead, bead filler, side tread, belt, and top tread, which are produced in separate member production processes, are sequentially attached to a molding drum, and this is used as one tire. The raw tires summarized in the above are molded. As such a molding system, as shown in FIG. 3, work stations S1 to S5 for assembling them for each tire component are provided, and a plurality of molding machines equipped with molding drums are provided between these work stations S1 to S5. A molding line L for manufacturing a plurality of green tires by moving D1, D2,..., D8 and sequentially assembling each tire component on each molding drum is known (for example, Patent Document 1, Patent Document 1). 2).
In the molding line L, when the tire component is a ribbon-like member continuously supplied from an extrusion device or a rubber coating device, such as a tread or a ply, the ribbon is sent to the work stations S2 to S5. The tire component manufacturing apparatus K2 to K5 for manufacturing the member can be installed, and the continuous ribbon member can be directly wound around the tire in the middle of molding, but the tire component is like a bead or a bead filler. In the case of a bead member, since this is placed at the end of the carcass ply and then the carcass ply is folded to narrow down the bead member, the bead member is different from the above tread or ply. A plurality of bead members produced by the production apparatus N are stored in the cartridge A, and this is assembled to the bead member assembly station by the carriage B. The molding machine D1, D2 carry the S1, ......, had to be supplied to D8.

By the way, in the conventional molding system, for example, as shown in FIG. 4, the bead members are connected to the molding lines Lij from a smaller number of bead member production apparatuses N1 to N4 with respect to a plurality of molding lines L11 to L44. When supplying to (i = 1 to 4, j = 1 to 4), one bead member production apparatus Ni is allocated to each of a plurality (four in this case) of molding lines Lij, and a plurality of lines are allocated. The group Gi (i = 1 to 4) is configured. That is, the molding lines L11 to L14 of the first line group G1 are sent from the production command issuing means P1j (j = 1 to 4) provided in the molding line L1j (j = 1 to 4) to the first line group G1. A production command is issued to the first bead member production apparatus N1 assigned to the first bead member production apparatus N1, and supply of necessary bead members is received from the first bead member production apparatus N1, and the molding lines L21 to L21 of the second line group G2 are received. Is produced from the production command issuing means P2j (j = 1 to 4) provided in the molding line L2j (j = 1 to 4) to the second bead member production apparatus N2 assigned to the second line group G2. A molding line Lkj (j = 1 to 4) of each line group Gk (k = 1 to 4), such as issuing a command and receiving supply of a necessary bead member from the second bead member production apparatus N2. The production command issuing means Pkj provided in Issue a production instruction to the bead member production apparatus Nk assigned to down group Gk, it was as get to supply bead members necessary.
That is, the conventional production command issuing means Pij sends a production command including necessary data such as the rim diameter and rubber type in addition to the number of supplies to the bead member production apparatus Ni of the same line group Gi, and the bead member production apparatus Ni produces the bead member based on the sent production command, stores it in the cartridge Ai, and sends it to the bead member assembling station S1 of the molding line Lij that issued the production command by the carriage Bi. It was.

In the conventional molding system described above, each of the bead member production apparatuses N1 to N4 produces, for example, a bead member that the bead member production apparatus N1 is for tires having a rim diameter of 16-19 and the preferred rubber type is b. The bead member production apparatus N2 produces a bead member for a tire having a rim diameter of 15-18 and a preferred rubber type a. The range of bead members that can be produced is bead member production apparatuses N1 to N4. Each is different.
In this way, when the bead member production apparatus Ni for which the molding line Lij issues a production command is assigned (fixed) in advance, it is not necessary to designate the bead member production apparatus one by one, and the required number of supplies. Since it is only necessary to specify the rim diameter and rubber type, there is an advantage that the production command is simple. However, in such a production command, even if the bead member production apparatus Ni of the same line group has not produced the required rim diameter and rubber type bead member, the production command issuing means Pij of the molding line Lij Since the necessary production command for the bead member is issued to the bead member production apparatus Ni in the same line group, there is a problem that an invalid production command is issued. In addition, when only the rubber type is different, the bead member production apparatus Ni can be adapted to the above production command. However, since operations such as changing production conditions are required, the supply of the bead member is delayed. There is a problem such as.

  The present invention has been made in view of conventional problems, and when there are a plurality of molding lines equipped with a plurality of molding machines for molding a raw tire, a bead member is efficiently supplied to these molding lines. An object of the present invention is to provide a production command method for a bead member that can be used.

The invention according to claim 1 of the present application includes a plurality of molding lines including a plurality of molding machines that circulate a plurality of work stations, and a plurality of tire constituent member manufacturing apparatuses provided at each work station, In a tire molding system including a plurality of sets of bead member production apparatuses that produce tire bead members to be supplied to a molding line, the bead members that are provided in each molding line and that produce the bead members to be supplied to the molding line A production command allocating method performed by a production command issuing means for issuing a production command to a production apparatus, wherein the production command issuing means stores information on a bead member produced by a set of bead member production apparatuses to which the molding line belongs. Providing first storage means and second storage means for storing information on bead members produced by another set of bead member production apparatuses, When the bead member required type lines can not be produced a set of bead member production apparatus belongs the molding line, the production instruction to allocate the supply of bead members required by the upper Symbol the molding line, the second storage Based on the information of the other set of bead member production apparatuses stored in the means, it is issued to the other set of bead member production apparatuses .
According to a second aspect of the present invention, in the bead member production command method according to the first aspect, the bead member is supplied to each molding line by a return carriage attached to the bead member production apparatus, and the supply is performed. When surplus occurs in the bead member, the surplus bead member is returned to the bead member production apparatus that produced the bead member, the surplus storage means is provided in the production command issuing means, When the bead member production apparatus to which the bead member is returned and the information for the surplus are stored, and when the bead member production apparatus to which the bead member has been returned issues a production command for the same bead member as the surplus bead member. Issues a production command of an amount obtained by subtracting the amount of surplus bead members taken out from the surplus storage means to the bead member production apparatus to which the surplus is returned. The features.

According to the present invention, since it is possible to minimize the change in the production conditions of the bead member production apparatus without performing an invalid production command, the bead member can be efficiently supplied to the molding line, Production efficiency in the molding process can be improved.
In addition, since the surplus can be managed, the loss of disposal can be reduced.

Hereinafter, the best mode of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an outline of a production finger method for a bead member in a molding system according to the best mode. In the figure, Lij (L11 to L14, L21 to L24, L31 to L34, L41 to L44) are obtained by sticking members such as a carcass ply, a bead, a bead filler, a side tread, a belt and a top tread in order to the molding drum. A molding line having a plurality of molding machines for molding a raw tire in which the tires are combined into one tire, and these molding lines Lij have the same configuration as the molding line L shown in FIG. N1 to N4 are bead member production apparatuses that produce bead members such as beads and bead fillers supplied to the plurality of molding lines Lij. In the molding system of this example, like the conventional molding system shown in FIG. 4, four molding lines Lij are grouped, and each of these molding lines Lij and the bead member production apparatus Ni is a line group Gi. (I = 1 to 4). Usually, in the molding lines Li1 to Li4 of the i-th line group Gi, the bead members produced by the bead member production apparatus Ni of the i-th line group Gi are stored in the cartridge Ai, and each molding line is formed by the carriage Bi. Lij (j = 1 to 4).
Each molding line Lij specifies the bead member specifications (rim diameter, rubber type, etc.) and amount used for molding, and assigns a bead member production device Nk for producing the bead member to produce the bead member. Production command issuing means Pij for issuing a production command for instructing the production and supply of the bead member to the apparatus Nk is provided. As shown in FIG. 2, the production command issuing means Pij includes an input unit 1 for inputting a required bead member specification (rim diameter, rubber type, etc.) and a usage amount, and a line group Gi to which the molding line Lij belongs. The bead member production apparatus Nj of the first storage unit m1 that stores information (the rim diameter, the rubber type, etc.) of the bead member produced by the bead member production apparatus Ni and the bead member production apparatus Nj of another line group Gj (j ≠ i) A storage unit Mij having a second storage unit m2 for storing bead member information, and a bead member production device Nk for producing and supplying the bead member based on the information stored in the storage unit Mij are allocated. A production command assigning unit 2 and an output unit 3 for issuing a production command for instructing production and supply of the bead member to the assigned bead member production apparatus Ni are provided.

  The major difference between the production command of this example and the conventional production command is that the bead member production device Nk that produces and supplies the bead member can be specified in addition to the line group Gi. That is, information (rim diameter, rubber type, etc.) of the bead member production apparatus Ni of the set Gi is stored in the first storage unit m1 of the storage unit Mij, and other lines are stored in the second storage unit m2. Since the information of the bead members produced by the bead member production device Nj of the group Gj (j ≠ i) is stored, the bead member production device Ni of the same line group Gi has the required rim diameter and rubber type bead member. If the bead member production apparatus Nj of the other line group Gj is producing the requested bead member even if it is not produced, the production command issuing means Pij of the molding line Lij is required as described above. A bead member production command can be issued to the bead member production apparatus Nj of the other line group Gj.

  For example, as shown in FIG. 1, the bead member production device N1 produces bead members for tires having a rim diameter of 16-19 and the preferred rubber type is b, and the bead member production device N2 has a rim diameter. A bead member for a tire of 15-18 and having a priority rubber type a is produced, and the bead member production apparatus N3 is a bead for a tire having a rim diameter of 16-19 and a priority rubber type of a. The bead member production apparatus N4 produces bead members for tires having a rim diameter of 15-18 and a preferred rubber type b, and the molding line L11 is a tire having a rim diameter of 19. Suppose that a bead member whose rubber type is b is required. When the rim diameter (19) and the rubber type (b) are input to the input unit 1 of the production command issuing means P11 by the worker of the molding line L11, the production command allocating unit 2 stores The specification of the bead member produced by the bead member production apparatus N1 of the group G1 is called from one storage unit m1, and it is checked whether the production and supply of the bead member can be assigned to the bead member production apparatus N1. . As a result, when the bead member production apparatus N1 can be assigned, the production and supply of the bead member is assigned to the bead member production apparatus N1. The output unit 3 issues a production command for commanding production and supply of the bead member to the allocated bead member production apparatus N1. The bead member production apparatus N1 that has received the production command produces a bead member having the specification specified in the production command by the designated amount, stores it in the cartridge A1, and sends it to the molding line L11 by the carriage B1.

When the molding line L11 requires a bead member for a tire having a rim diameter of 15 and the rubber type is b, the input part 1 of the production command issuing means P11 includes the rim diameter (15) and The rubber type (b) is input by the worker on the molding line L11. The production command assigning unit 2 calls the specifications of the bead members produced by the bead member production device N1 of the line group G1 from the first storage unit m1 of the storage unit M11, and beads the production and supply of the bead members. It is checked whether it can be allocated to the member production apparatus N1. Since the bead member production device N1 produces bead members for tires having a rim diameter of 16-19 and the preferred rubber type is b, the bead member production device N1 cannot be assigned to the bead member production device N1. Therefore, the production command allocating unit 2 calls the specification of the bead member produced by the bead member production device N2 of the next line group G2 from the second storage unit m2 of the storage unit M11, It is checked whether the supply can be allocated to the bead member production apparatus N2. Such an operation is repeated until a bead member production apparatus N that can be assigned is found.
In this example, the bead member production apparatus N4 produces bead members for tires having a rim diameter of 15-18 and the preferred rubber type is b. Therefore, the bead member production apparatus N4 assigned in the fourth survey is used. Can be found.
When the bead member production apparatus N4 to be allocated is found, the production and supply of the bead member is allocated to the bead member production apparatus N4. The output unit 3 issues a production command for commanding the production and supply of the bead member to the allocated bead member production apparatus N4. The bead member production apparatus N4 that has received the production command produces a bead member having the specification specified in the production command by the designated amount, stores it in the cartridge A4, and sends it to the molding line L11 by the carriage B4.
In addition, in the molding line Lij, a bead member that can be produced by any of the bead member production apparatuses N1 to N4 is used. Therefore, if the allocation is impossible, the operator is prompted to re-enter the specification as an input error.

  When the molding line L11 requires a bead member for a tire having a rim diameter of 17 and the rubber type is a, in the conventional molding system, the rubber type produced by the bead member production apparatus N1 is changed from b. The required bead member is produced by changing to a, but in the molding system of this example, the bead member production device to be assigned can be designated as the bead member production device N2 in the same manner as described above. Therefore, since it is not necessary to change the production conditions of the bead member production apparatus, the production and supply of the bead member can be performed smoothly.

By the way, in the molding line Lij, there are eight molding machines D1 to D8, each of which makes four rounds of the work stations S1 to S5 to produce 32 raw tires. In the bead member production apparatus Ni, The number of bead members supplied at one time is a bead member for 32 tires (the number of bead portions is 64 on the left and right).
However, there are cases where only seven molding machines D move due to the number of tires to be produced. At this time, the bead members for four tires remain. The surplus bead members are stored again in the cartridge A and returned to the bead member production apparatus N by the carriage B.
Conventionally, in the bead member production apparatus N, the returned bead member is stored, and when a production command for the same bead member is issued next, an operator of the bead member production apparatus N issues the issued production command. Was instructed to produce a quantity obtained by subtracting the surplus bead member from the production quantity specified by the company, but the management was difficult. In addition, when the management is insufficient, the surplus is discarded, so that a loss of destruction occurs.
Accordingly, in this example, the input part 1 of the production command issuing means Pij inputs the specifications of the surplus bead members, the surplus number, and information on the bead member production apparatus Nk that produced the bead members, and stores them. The specification of the bead member produced by the bead member production device Ni of the line group Gi is called from the first storage unit m1 or the second storage unit m2 of the part Mij, and the first storage unit m1 or second The above specifications and the surplus number are added to the information of the bead member production apparatus Ni stored in the storage unit m2. When the production command assigning unit 2 assigns the production of the bead member having the same specifications as the surplus bead member to the bead member production apparatus Ni, the production amount is calculated from the production amount input from the input unit 1. The amount is rewritten to the amount obtained by subtracting the amount of the excess bead member. The output unit 3 issues the production command for the rewritten production amount to the bead member production apparatus Ni to which the surplus has been returned.
As a result, it is possible to sufficiently manage the surplus portion, thereby reducing the loss of disposal.

In this best mode, a plurality of molding lines Lij (i = 1 to 4, j = 1 to 4) and bead member production apparatuses N1 to N4 for producing and supplying bead members to these molding lines Lij are provided. In the molding system in which the bead member production apparatus Ni and the molding lines Li1 to Li4 constitute a plurality of line groups Gi (i = 1 to 4), the bead member production of the line group Gi is included in each molding line Lij. A first storage unit m1 that stores information on the apparatus Ni (rim diameter, rubber type, etc.), and a second storage unit m2 that stores information on bead members produced by the bead member production device Nj of another line group Gj; When the production command issuing means Pij having the storage unit Mij is provided and the bead member production device Ni of the same line group Gi is not producing the required rim diameter and rubber type bead member, the molding line Lij's production fingers The command issuing means Pij can issue the necessary bead member production command to the bead member production device Nj of the other line group Gj, so that an invalid production command can be issued. The change in the production conditions of the bead member production apparatus can be minimized. Therefore, the bead member can be efficiently supplied to the molding line Lij, and the production efficiency in the molding process can be improved.
In addition, for the convenience of the expected production number of tires, when surplus bead members are generated, the surplus bead members are returned to the bead member production apparatus, and the specifications of the surplus bead members, the surplus number, and the bead Information on the bead member production device Nk that produced the member is added to the information on the bead member production device Nk stored in the first storage unit m1 or the second storage unit m2 of the storage unit Mij, and the production command assigning unit When the production of the bead member having the same specifications as the surplus bead member 2 is allocated to the bead member production apparatus Nk, the production amount is rewritten to the amount obtained by subtracting the surplus portion from the necessary production amount. Therefore, it is possible to sufficiently manage the surplus and to reduce the loss of disposal.

In the best mode described above, the number of molding machines D, molding lines, line groups G, and bead member production apparatuses is 8 units, 4 lines, 4 groups, 4 units, respectively. It is not limited.
Further, in the above example, the information on the bead member produced by the bead member production device Nj of the other line group Gj is stored in the storage unit Mij second storage unit m2 of the production command issuing means Pij. A storage unit may be provided for each bead member production apparatus Nj.
In the above example, the bead member production apparatus can change the type of rubber to be produced, but may be a bead member production apparatus in which the rubber type is fixed.
In the above example, the specification of the surplus bead member, the surplus number, and the information of the bead member production apparatus Nk that produced the bead member are stored in the first storage unit m1 or the second storage unit of the storage unit Mij. In addition to the information of the bead member production apparatus Nk stored in m2, the storage unit Mij is provided with a surplus storage means for storing information on the surplus bead member, and the bead member is returned to the bead member You may make it memorize | store the information for a production apparatus and the said surplus.
