According to the present invention, the manager or the person in charge can easily grasp the overall situation of the industrial machines in the group.
The above and other objects features and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings in which a preferred embodiment of the present invention is shown by way of illustrative example.
Now, the present invention will be described through embodiments of the invention. The following embodiments will not limit the invention according to the claims. Not all combinations of features described in the embodiments are necessarily essential to the solutions of the invention.
The industrial machine management apparatus 10 is, for example, a personal computer or the like, but may be another type of digital computer. The industrial machine management apparatus 10 includes a control unit 12, an input unit 14, a display unit 16, and a storage unit 18. The industrial machine management apparatus 10 is connected to individual injection molding machines M via a network 26 to exchange information with each other. The network 26 is, for example, a LAN or the like, but may have any configuration, regardless of a wired or wireless network and whether the signal to be communicated is a digital signal or an analog signal, as long as it enables mutual communication between the industrial machine management apparatus 10 and each of the injection molding machines M.
The control unit 12 is, for example, a CPU, but may be another type of processor such as a microprocessor etc. The input unit 14 is, for example, a keyboard, but may include a mouse, a card reader, a touch panel and other kinds of input devices. The display unit 16 is, for example, a liquid crystal display, but may be another type of display such as a CRT (cathode-ray tube) display, an organic EL display and the like. The storage unit 18 stores information on which groups multiple injection molding machines M belong to. As to the groups, description will be detailed later.
The control unit 12 includes a management information calculating unit 20 and a display control unit 22. The control unit 12 may additionally include a group selecting unit 24. The management information calculating unit 20, based on information on the production by each individual injection molding machine M, calculates a statistic of information on the overall production by the injection molding machines M belonging to a group, as management information. The management information will be described in detail later. The display control unit 22 calculates a control signal for displaying the management information calculated by the management information calculating unit 20 and others on the display unit 16 and outputs the control signal to the display unit 16. In the following description, the fact that the display unit 16 is controlled by the display control unit 22 will not be mentioned, but the display unit 16 is always controlled by the display control unit 22 unless otherwise specified. The group selecting unit 24 selects a group designated by the operator operating the input unit 14.
The multiple injection molding machines M in the factory are classified into groups, in advance, according to predetermined criteria. The industrial machine management apparatus 10 of the present embodiment displays overall management information of the injection molding machines M belonging to the group on the display unit 16 for each group. Now, the groups will be illustrated.
The management information calculating unit 20 calculates information on the total production by the injection molding machines M that belong to each of the groups (1) to (3) from the information on the production by each individual machine of the injection molding machines M belonging to each of the groups (1) to (3).
The information on the production by each individual injection molding machine M indicates, for example, the operation status of each injection molding machine M, i.e., automatic operation in progress, manual operation in progress, operation suspended, or the like. The statistic of the information on the overall production by the injection molding machines M in each of the groups (1) to (3) may be, for example, the overall operating rate of the injection molding machines M belonging to each of the groups (1) to (3). In the example shown in
Other examples of individual information may include the power consumption, the quantity of products, the amount of resin consumption and the non-defective rate of molded products as to each individual injection molding machine M and the working time of the operator in charge of each individual injection molding machine M. Other examples of management information may include the total power consumption, the total quantity of products, the total amount of resin consumption, the non-defective rate of molded products and the total working time as to all the injection molding machines M belonging to each group.
In
It should be noted that the group selection buttons 28 are not limited to the display on the display unit 16, but may be mechanical buttons to be pressed by the operator's finger. The group selecting unit 24 may be configured to automatically select a group that the operator is in charge of, from the operator ID input through the input unit 14 when the operator logs in the industrial machine management apparatus 10. Furthermore, the group selecting unit 24 may read the identification information of the operator stored in the IC card carried by each operator through the input unit 14 and automatically select the group which the operator is in charge of.
For example, in order to manage a production line (group), the production line leader, i.e., the person in charge of the line, needs to know information on the total operating rate of the injection molding machines M of the group to be managed, the total power consumption, the total quantity of the products, the amount of resin consumption, the non-defective rate of molded products, the total of the working time and other items. Conventionally, such information has not been presented, while only individual information of each of injection molding machines M belonging to a group has been displayed. Only with the display of individual information on each individual machine, it has been difficult for the line manager to grasp the total status of the injection molding machines M of the group at a glance.
In the present embodiment, the industrial machine management apparatus 10 includes: the management information calculating unit 20 that, based on the information concerning the production by each of multiple injection molding machines M classified into groups according to predetermined criteria, calculates as management information, a statistic of information on the total production by injection molding machines M belonging to each of the groups; and the display unit 16 that displays the management information of the groups. With this configuration, the group manager can grasp the entire status of the injection molding machines M of each of the groups at a glance.
Further, the industrial machine management apparatus 10 has the group selecting unit 24 for selecting one of the groups, and the display unit 16 displays the management information of the group selected by the group selecting unit 24. This makes it possible to display the management information of the injection molding machines M of one group on the display unit 16.
In addition, the group selecting unit 24 selects a group based on the identification information of the operator who operates the industrial machine management apparatus 10. Thereby, the management information of the group managed by the operator can be automatically displayed on the display unit 16.
The management information calculating unit 20 calculates, as management information, at least one of the total operating rate of the industrial machines belonging to the group, the total power consumption of the industrial machines belonging to the group, the total amount of the material used in the industrial machines belonging to the group, the total number of products manufactured by the industrial machines belonging to the group, the non-defective rate or the defective rate of the products manufactured by the industrial machines belonging to the group, and the total work time of workers who operate the industrial machines belonging to the group. Thus, it is possible to calculate the management information corresponding to the injection molding machines M to be managed by the manager.
The industrial machine management apparatus 10 manages the injection molding machines M. Application of the industrial machine management apparatus 10 to the management of a large number of injection molding machines M installed in a factory makes it possible to reduce the labor of the person in charge of the machines.
Many injection molding machines M in a factory are managed differently by qualified persons in charge such as, for example, the factory manager, line leaders, maintenance workers, workers, etc., according to their responsible ranges. For example, the factory manager manages all the injection molding machines M in the entire factory, the line leader manages the injection molding machines M for each line determined according to the type and item of molded products to be formed, the maintenance worker manages injection molding machines M depending on the machine model, and the worker manages each individual injection molding machine M. Therefore, in the industrial machine management apparatus 10 of the present embodiment, in order to classify the injection molding machines M into groups by multiple grouping methods depending on the qualifications of the persons in charge, layers are set up depending on the qualifications of the persons in charge.
In the first layer, injection molding machines M are grouped on the basis of a factory where the injection molding machines M are installed. That is, all the injection molding machines M1 to M10 in the factory are classified into one group A. In the second layer, the injection molding machines M1 to M10 that belong to the single group A in the layer (the first layer), which is one level higher than the second layer, are classified into groups (1) to (3) according the production line to which the injection molding machines M belong. More specifically, the injection molding machines M1 to M3 are classified into group (1), the injection molding machines M4 to M8 are classified into group (2), and the injection molding machines M9 and M10 are classified into group (3).
In the third layer, the injection molding machines M1 to M3 belonging to the group (1), the injection molding machines M4 to M8 belonging to group (2) and the injection molding machines M9 and M10 belonging to group (3) in the layer (the second layer), which is one level higher than the third layer, are classified into groups a to f according to the machine model of the injection molding machines M. In the fourth layer, the machines are classified into groups 1 to 10, or individual injection molding machines M.
In the above description, the injection molding machines M are classified on the basis of the factory, the production line, and the machine models of the injection molding machines M. However, the criteria of classification of the injection molding machines M are not limited to the above, but the injection molding machines M may be classified based on at least one of the specifications of the injection molding machines M (e.g., mold clamping force, injection volume, etc.), the types thereof (horizontal molding machine, vertical molding machine, two-material molding machine, etc.), the types of material used therein (polycarbonate, polypropylene, acrylonitrile-butadiene-styrene, etc.), the types of molded products formed thereby (gears, connectors, lenses, etc.) and the workers, etc., managing the injection molding machines M, or based on any combination thereof.
The storage unit 18 stores groups belonging to each layer and the injection molding machines M belonging to the groups, in association with each other.
The display unit 16 displays information on the layer selected by the layer selecting unit 30.
It should be noted that the layer selection buttons 32 are not limited to the display on the display unit 16 but may be mechanical buttons to be pressed by the operator's finger. Further, the layer selecting unit 30 may be configured to automatically select a layer corresponding to the qualification of the operator, from the operator ID (identification information) input through the input unit 14 when the operator logs in the industrial machine management apparatus 10. Furthermore, the group selecting unit 24 may read the identification information of the operator stored in the IC card carried by the operator through the input unit 14 and automatically select a layer corresponding to the qualification of the operator.
When the first layer is selected in the layer selecting unit 30, as shown in
When the second layer is selected in the layer selecting unit 30, as shown in
When the third layer is selected in the layer selecting unit 30, as shown in
When the fourth layer is selected in the layer selecting unit 30, as shown in
In the first embodiment, the display unit 16 is configured to display information on the injection molding machines M that belong to the group selected by the group selecting unit 24. In the second embodiment, the display unit 16 is configured to display information on the injection molding machines M that belong to each group in the layer selected by the layer selecting unit 30.
Layers or groups may be selected as appropriate by the layer selecting unit 30 or the group selecting unit 24 based on the identification information of the operator who operates the industrial machine management apparatus 10.
For example, when the operator is “Sato”, the layer selecting unit 30 selects the first layer including the injection molding machines M1 to M10 which “Sato” manages as the factory manager. When the operator is “Suzuki”, the group selecting unit 24 selects the groups “a” and “c” which “Suzuki” manages as a maintenance worker. Furthermore, when the operator is “Yamada”, the group selecting unit 24 selects the groups 4, 7, 8 which “Yamada” manages as a worker.
Multiple injection molding machines M are classified into groups based on different criteria for every layer. In the top layer, all the industrial machines belong to one group. In a lower layer than the top layer, the multiple industrial machines belonging to one group in the layer that is one level higher than the lower layer are classified into (or belong to) one group or multiple groups. The management classification of the injection molding machines M is different depending on the qualification of the person in charge. With this configuration, it is possible to classify the machines into groups depending on the management classification of injection molding machines M.
The industrial machine management apparatus 10 includes the storage unit 18 that stores the groups belonging to each layer and the industrial machines belonging to the groups in association with each other. The storage unit 18 stores the information in which groups to which the injection molding machines M belong in each layer are registered, as the attribute of the injection molding machine M. That is, the injection molding machines M that are classified into groups according to criteria that differ depending on the layers can be stored in the storage unit 18.
The industrial machine management apparatus 10 also includes the layer selecting unit 30 for selecting one layer from among the multiple layers, and the display unit 16 displays management information concerning each group in the one layer selected by the layer selecting unit 30. Thereby, it is possible to display on the display unit 16 the management information of the groups into which the machines are classified based on the qualification of the operator.
Further, the layer selecting unit 30 selects one layer based on the identification information of the operator who operates the industrial machine management apparatus 10. This enables automatic display of the management information concerning the group to be managed by the operator on the display unit 16.
The criteria on which classifying of the injection molding machines M is based include one or a combination of the factory where the injection molding machines M are installed, the production line to which the injection molding machine M belongs, the model of the injection molding machine M, the specification of the injection molding machine M, the type of the injection molding machine M, the type of material used in the injection molding machine M, the type of products manufactured by the injection molding machine M, and the person in charge who manages the injection molding machine M. As a result, it is possible to classify the injection molding machines M into groups based on the injection molding machines M to be managed by the person in charge.
One or multiple industrial machine management apparatuses 10 may be installed in a factory.
Each group includes one industrial machine management apparatus 10 for calculating the overall management information of the industrial machines belonging to the group. As a result, it is possible to distribute calculation processing of management information and the like, hence reduce the load on each industrial machine management apparatus 10.
In addition, each group includes one display unit 16. As a result, the person in charge of each group or each of the injection molding machines M1 to M10 can check the information displayed on the display unit 16 in a place close to the injection molding machine M belonging to each group.
Although the present invention has been described based on the first to third embodiments, the specific configuration of the invention is not limited to the above embodiments, but changes in design and the like without departing from the scope of the present invention should also be included in the present invention.
Though the present invention has been described with reference to the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiment. It goes without saying that various modifications or improvements can be added to the above embodiments. It is obvious from the description of the scope of the claims that configurations with such modifications or improvements can be included in the technical scope of the present invention.
