The flowchart of a Web sales method.

  In FIG. 1, a product sales server 18 is connected to a large number of PCs 12 on the Internet 11, and the PCs 12 and the product sales server 18 can exchange data via the Internet 11. Each Web visitor 13 can access the product sales server 18 from his / her PC 12 to obtain information about a product desired to be purchased from the product sales server 18 or purchase a product.

  The product sales server 18 is equipped with a database 19 that covers information (eg, size, data, type, weight, etc.) related to the sales product and its parts. The Web sales system is implemented as a program in the product sales server 18 and includes an input screen presentation unit 20, a narrowing unit 21, a calculation unit 22, a combination presentation unit 23, and a sales procedure unit 24.

In FIG. 2, product sales in the Web sales system are performed in the following order.
S40: Selection method selection S41: Application selection S42: Axis configuration selection S43: Mechanical step 1 selection S44: Actuator selection S45: Mechanical step 2 selection S46: Mechanical step 2.5 selection S47: Mechanical step 3 selection

After S47, the process may proceed to S60 or S61, or may proceed to S70 immediately depending on the instruction of the Web visitor 13.
S60: System configuration selection. The system configuration selection is a single selection of RS and LX (KU). RS, LX, and KU are names given by the seller to the actuators by type, and KU is an alias for LX. Since one axis is composed of one actuator, the three-axis actuator is composed of three actuators. In that case, each actuator corresponding to one axis becomes a part of a three-axis actuator as a product.
S61: System configuration selection. The system configuration selection is a composite selection of RS and LX (KU).
S62: Motor selection S63: Display at SKU (model number) level. In this example, the model number of the seller's product is SKU + number.

After S63, it is possible to proceed to S70 depending on the desire of the Web visitor 13, or to proceed to S64.

S70: eCatalog (electronic catalog) cart

  3 to 22 are screens sequentially displayed on the display of his / her PC 12 when the Web visitor 13 accesses the Web sales system of the product sales server 18 and purchases a product.

  On the corresponding screen in S40 of FIG. 3, the Web visitor 13 selects either “select from the application” or “select from the axis configuration” for the purchased product.

  The corresponding screen in S41 of FIG. 4 is a screen displayed when the Web visitor 13 selects “Select purchased product from application” in S40. Here, the application is used as an ordinary name of the product (eg, dispenser, welding head, nut runner,...). In this screen, a plurality of products are grouped for the convenience of selection by the Web visitor 13, and each product is displayed in a group for each group to which the product belongs.

  The correspondence screen of S42 in FIG. 5 is a screen that is displayed next when the Web visitor 13 selects “select from axis configuration” in S40 or when a predetermined product is selected in the screen of S41 in FIG. is there. In the screen, the vertical column at the left end is the specification item of the actuator, and the Web visitor 13 selects one of the options arranged in a horizontal row for each specification item.

  From FIG. 5 to FIG. 10, the narrowing-down means 21 presents the Web visitor 13 on the PC 12 as a Web input screen. The design specification input by the Web visitor 13 includes input of each numerical value, selection of a numerical value, and selection of a type. In the screen of FIG. 5, the Web visitor 13 can select “1 axis”, “2 axes”, or “3 axes” regarding the axis configuration. “1-axis”, “2-axis” and “3-axis” mean a 1-axis actuator, 2-axis actuator and 3-axis actuator, respectively. Hereinafter, the embodiment will be described on the assumption that the web visitor 13 has selected the three-axis actuator.

  For example, the actuator as a product corresponds to a ball screw integrated linear motion guide bearing disclosed in Utility Model Registration No. 3138342. When the screw shaft of the ball screw is rotated by the motor, the slider moves in the axial direction.

  In FIG. 5 and the like, the first, second, and third axes of the three-axis actuator mean the x-axis, y-axis, and z-axis of the xyz coordinate system perpendicular to each other. In the three-axis actuator, the x-axis supports the y-axis so that it can be displaced in the extending direction of the x-axis, and the y-axis supports the z-axis so that it can displace in the extending direction of the y-axis.

  6 and 7 are screens corresponding to S43, and the Web visitor 13 is to input design specifications for the use conditions of the three-axis actuator on the screen. The image of the speed diagram in FIG. 7 shows that the web visitor 13 has “speed”, “stroke”, “acceleration time”, “deceleration time”, and “stop time” in the patterns 1, 2, 3, and 4 in FIG. When design specifications are input to each specification item, their definitions are displayed so that they can be visually understood. A workpiece is an object to be processed using a three-axis actuator.

  On the corresponding screen in S44 of FIG. 8, the Web visitor 13 selects the presence / absence of a motor in the actuator and the type of actuator as specification items. Depending on the presence or absence of a motor, one of the broken line frames (in the upper broken line frame for the motorless type, in the lower broken line frame for the motor equipped type) is displayed. In addition, the presence or absence of a motor and the selection of a motor do not require special electrical knowledge, and are within the range of general knowledge of a machine designer.

  9 and 10, the Web visitor 13 inputs an axis selection condition as a specification item.

  The corresponding screen in S46 of FIG. 11 is a screen that the combination presentation means 23 presents to the Web visitor 13. The screen displays a combination of three axes as three machine parts, and a safety factor and a running life for rails, ball screws, and bearings that are sub-machine parts of each axis. The combinations of the three axes on the screen are obtained by the narrowing-down means 21 using the predetermined narrowing-down method based on the design specifications input by the Web visitor 13 on the Web input screen up to FIG. The safety factor and the running life are calculated by the calculation means 22 based on the design specifications input by the Web visitor 13 on the Web input screen up to FIG. This is a purchase index when deciding whether to purchase a 3-axis actuator. In the screen, the axis in each combination is identified by a model number (part name) as a name. In addition to the purchase index, the price of each combination can be presented as appropriate to the web visitor 13.

  The calculation means 22 does not calculate the safety factor and the travel life as the purchase index of the Web visitor 13 for all combinations, but calculates the purchase index for only the combinations narrowed down by the narrowing means 21 using a predetermined calculation formula. be able to. Further, the narrowing-down means 21 gives the information on the combination appropriately narrowed down in the intermediate narrowing stage to the narrowing-down means 21 and returns the purchase index calculated by the calculating means 22 for those combinations from the calculating means 22 and returned. Further, the combination may be further narrowed down based on the purchase index information, and the combination may be finally narrowed down. Note that the number of intermediate narrowing steps is not limited to one, and a plurality of intermediate narrowing steps are used. That is, the narrowing means 21 and the computing unit 22 exchange information appropriately in a plurality of intermediate narrowing steps, and the narrowing means 21 finally narrows down. It is also possible to adopt a narrowing-down method that outputs combinations. Further, the calculation value output to the narrowing-down means 21 by the calculation means 22 in the intermediate narrowing-down stage can be an intermediate calculation value or an index different from the purchase index that is finally output to the combination presentation means 23.

  The safety factor is defined as load capacity / allowable load. The load capacity is the maximum load that the 3-axis actuator can withstand without being damaged by design, and the allowable load is calculated as the load actually applied to the 3-axis actuator from the design specifications input by the Web visitor 13 A predetermined amount is added to the applied load. The safety factor is calculated based on the input design specifications from the data of each part of each combination and the Web visitor 13 using an arithmetic expression that takes into account the sales or technical experience of the seller of the three-axis actuator.

  The sales or technical experience of the seller is the knowledge and knowledge acquired by the seller through the sales or technical experience. The seller has not only disclosed it to other companies but also conceals it. (Example: business or technical know-how). Adopting a narrowing method or index calculation that incorporates the sales or technical experience of the seller's concealment makes it possible to differentiate against similar websites of competitors or enhance originality. It becomes possible to provide useful combination information to the visitor 13.

  The sales or technical experience of the seller of the three-axis actuator to the calculation formula for the safety factor and the running life is specifically determined by adding a predetermined term to the calculation formula or selecting a predetermined coefficient value. It is taken into account.

  The Web visitor 13 inputs the usage conditions (for example, the weight and dimensions of the workpiece) of the triaxial actuator on the screen of FIG. 6 and the like, but the combination narrowed down by the narrowing means 21 needs to satisfy the usage conditions. Whether or not the combination of the three axes satisfies the use condition is calculated based on the data of each axis by calculating the operation amount (displacement amount) of the three-axis actuator and whether or not the use condition is satisfied. Determined by examining.

  The movement amount of the third axis is calculated by first calculating the movement amount of the third axis (z axis) with respect to the workpiece, and then calculating the movement amount of the second axis (y axis) by incorporating the calculation result. Then, the movement amount of the first axis (x axis) is calculated by incorporating the calculation result. As the final movement amount of the first axis (x-axis), all the movement amounts of the x-axis, y-axis, and z-axis are calculated, and it is examined whether these satisfy the use conditions.

  The Web visitor 13 selects a desired combination on the screen of FIG. At that time, the Web visitor 13 determines which combination is desired by referring to an index (eg, safety factor and running life) of each combination. The screen shown in FIG. 11 is presented to the web visitor 13 by the combination presentation means 23.

  On the corresponding screen in S47 of FIG. 12, the Web visitor 13 inputs text for additional machining for each axis for the combination selected from the screen of FIG. When the Web visitor 13 clicks the “Next” button on the screen of FIG. 12, the process proceeds to S60 (FIG. 13) or S61 (FIG. 14), and when the “Add Cart” button is clicked, the process proceeds to S70.

  Although a specific screen corresponding to S70 is not shown, the screen is generated by the sales procedure means 24 and presented to the Web visitor 13. The Web visitor 13 inputs a purchase intention display, a purchase price payment method, a transport destination and a transport date of the purchased product on the screen.

  The corresponding screen in S60 of FIG. 13 is a screen when the axis of the actuator has a single configuration, and the corresponding screen of S61 in FIG. 14 is a screen when the axis of the actuator has a composite configuration. 13 (S60), FIG. 14 (S61), and FIG. 17 (S62) are web input screens presented by the narrowing means 21 to the web visitors 13. As described above, the narrowing down means 21 appropriately presents the corresponding Web input screens to the Web visitors 13 in a plurality of stages. Corresponding to each stage of the narrowing-down means 21, the narrowing-down means 21 performs narrowing as appropriate in a plurality of stages, the calculating means 22 also calculates indices appropriately in multiple stages, and the combination presentation means 23 also in multiple stages. Present combinations as appropriate.

  The single structure (FIG. 13) means that all three axes of the actuator are of the same type, and the composite structure (FIG. 14) means that the three axes of the actuator are composed of a plurality of types. In the screen of FIG. 11 described above, LX and KU of the shaft model number represent types. The rectangular blocks in the control system selection column of FIGS. 13 and 14 are blank, but actually, the images illustrated in FIGS. 15 and 16 are displayed.

  The web visitor 13 selects a desired control system, manufacturer, compatible control, and connection method between the controller and the servo amplifier on the screen of FIG. 13 or FIG. The Web visitor 13 can select the same manufacturer or a different manufacturer for the controller and the motor. The column “Connection between controller and servo amplifier” is displayed only when the AC servo is used, and can be selected only at that time. In STEP 1 (FIGS. 13 and 14) in the selection, the Web visitor 13 selects one of the motion network and the general-purpose interface, and in STEP 2 (FIGS. 13 and 14), (a) MECHALINK- II, MECHATROLINK-III, SSCNET III, EtherCAT, MVLINK, and CANopen, (b) Select pulse train or analog.

  The selection screens of FIGS. 13 and 14 show, in addition to the selection of the control system, if the product that the Web visitor 13 desires to provide information or purchase is a three-axis actuator, the corresponding control and controller If the connection of the servo amplifier is not selected, the Web visitor 13 is requested to select (input of the selected item) based on the knowledge that a product that cannot be established is produced. Specifically, the request for selection is made by a web input screen presented to the web visitor 13 by the input screen presentation means 20, and the web visitor 13 inputs the selection to the web input screen.

  In the control system, there are an AC servo motor, a stepping motor, and an RS as a drive source of the actuator. In the case of an AC servo motor, selection is made regarding compatible control and connection between the control and the controller-servo amplifier. In the case of stepping motors, selection is added regarding the control that can be supported. In the case of RS, it is not necessary to select both the control that can be handled and the connection between the control and the servo amplifier.

  FIG. 15 about the options displayed on the PC 12 of the Web visitor 13 when the control system uses an AC servo motor illustrates three options for the control system. In the case of the control system, the triaxial actuator is driven by an AC servo motor. The servo amplifier functions as a drive unit that generates a drive signal to be driven by the drive method of the 3-axis actuator from the control signal from the controller and outputs the drive signal to the 3-axis actuator. The servo amplifier as the drive unit is simply received from the controller. It only amplifies the analog control signal. In the option described at the bottom of FIG. 15, a PC (personal computer) plays the role of a controller. In the three options, the Web visitor 13 selects a controller type in the control system.

  In FIG. 16 about options displayed on the PC 12 of the Web visitor 13 when the control system uses a stepping motor, three options for the control system are illustrated. In the case of the control system, the triaxial actuator is driven by a stepping motor. The driver, the driver with built-in positioning function, and the CC-Link compatible driver function as a drive unit that generates a drive signal to be driven by the drive method of the 3-axis actuator from the control signal and outputs it to the 3-axis actuator. The pulse train control signal is input, the positioning function built-in driver is connected to the I / O port of the controller, and the CC-Link compatible driver is connected to the controller via CC-Link. In the three options, the Web visitor 13 selects the type of connection method between the controller and the drive unit in the control system.

  The corresponding screen of S62 in FIG. 17 is displayed on the PC 12 when the Web visitor 13 clicks “motor” in FIG. 13 or FIG. 14, and the Web visitor 13 is used in the control system on the screen. Select the motor manufacturer.

In the example of the screen, it is assumed that the Web visitor 13 has selected “select information system interface” in the selection of the communication unit on the screen of FIG. The Web visitor 13 selects a desired communication method on the screen of FIG.

  The corresponding screen of S66 in FIGS. 22 and 23 is different from the corresponding screen of S63 in FIGS. 18 and 19 in that the buttons “Return”, “Next” and “Print screen display” at the end (FIG. 19) are removed. It is the same except that. This screen is also a screen for the sales procedure means 24 to allow the Web visitor 13 to confirm the purchased product in the course of the purchase procedure. When the Web visitor 13 clicks the “Add Cart” button in FIG. 23, the process proceeds to S70.

  With reference to FIG. 24, the narrowing method performed by the narrowing means 21 will be described while describing the number of combinations of the three axes of the three-axis actuator. As an example, a combination in which all three axes are LX types will be described. In FIG. 24, the small turtle, the middle turtle, and the parent turtle mean the z-axis, the y-axis, and the x-axis, respectively. In the three-axis actuator, as described above, the x-axis (parent turtle, the first axis described above) is fixed to the base, and the y-axis (center turtle, the second axis described above) is relative to the x-axis. The z axis (Kogame, the third axis described above) is assembled to the y axis so as to be movable relative to the y axis.

  The axes are LX15, LX20, LX26, LX30, and LX45 from the smallest size. The combinations extracted by the narrowing-down method of the narrowing means 21 are limited to (a1) combinations in which the shaft size on the support side is equal to or larger than the shaft size on the supported side. The limitation (a1) is based on the sales or technical experience of the seller of the 3-axis actuator. In the three-axis actuator sold by this seller, there are 28 possible combinations from the number 1 to 28 by the limitation (a1). As will be described later, the number of possible combinations increases if the classification is further made based on the presence or absence of a cover, the difference in leads, or the difference in blocks.

  The items "Cover", "Lead", and "Block" described next to FIG. 24 are the types of "Cover", "Lead", and "Block" for the little turtle, middle turtle, and parent turtle in each combination. Numbers are shown. The cover is a member that covers the shaft so that dust does not enter the shaft. The lead is an axial position amount that changes as the ball makes one rotation. In FIG. 24, all the axes are provided with a cover, and the mixture of the axes with and without the cover is excluded in this example.

  For example, in No. 5 (No. 5), there is only one kind of the tortoise (LX15), the middle tortoise (LX20), and the parent tortoise (LX26) with a cover. As for the lead, there is only one type for the small turtle (LX15), but there are two types for the medium turtle (LX20) and the parent turtle (LX26). Regarding the block, there is only one type for the small turtle (LX15), but there are two types for each of the medium turtle (LX20) and the parent turtle (LX26).

  Therefore, the number of combinations of No. 5 is 1 × 1 × 1 × 1 × 2 × 2 × 1 × 2 × 2 = 16. The 16 is entered in the total column at the right end of the 5th row. Thus, the total number of combinations with a cover is described at the bottom of the rightmost column as the sum of the rightmost numbers 1, 4, 4, 16, 16, 32,. 4441. Therefore, if the combination without a cover is included, there are 4882 × 2 8882 combinations of the axes of the seller's three-axis actuator.

  That is, although the narrowing-down means 21 has been described as narrowing down the combinations by the limitation (a1), the narrowing-down is still insufficient with the limitation (a1) alone. A narrowing method by the narrowing means 21 will be specifically described. This narrowing-down algorithm has been devised by the present inventor based on sales or technical experience of the seller of the three-axis actuator.

  For convenience of explanation, ranks (grades) 1, 2, 3,... Are assigned in order from the smallest to the small turtle, the middle turtle, and the parent turtle. For example, in FIG. 24, the ranks of LX15, LX20, LX26, LX30, and LX45 are 1, 2, 3, 4, and 5, respectively. In addition, U, V, and W are ranks of small turtle, middle turtle, and parent turtle, respectively.

  The numbers in FIG. 24 are arranged in order of ascending order of rank (smallest size) with the priority order set to U, V, and W (supported side axis priority). Therefore, the greater the combination, the greater the strength and the safety factor. As the number increases, the possibility of satisfying the above condition increases. In general, the higher the number, the higher the price.

  First, the narrowing-down means 21 calculates the safety coefficient of the tortoise alone in the ascending order of U (smallest order) only for the tortoise, and determines whether or not the condition is greater than a predetermined value (for example, 10). Then, as soon as a turtle satisfying the condition is found, the condition determination for the turtle alone is stopped. The found turtle U is U1. From the combinations in FIG. 24, only the turtles with U = U1 and U = U1 + 1 are left as the subsequent determination targets, and combinations of other ranks (U <U1 and U> U1 + 1) are excluded from the subsequent determination targets. For example, if U1 = 2 (LX20 rank), combinations of numbers 10 to 24 are left.

  The reason why the combination of U = U1 and U = U1 + 1 is left as a determination target is as follows. For the combination of small turtle and medium turtle, fixed to U = U1 following the condition determination of single turtle. In addition, the condition determination for the combination of small turtle + middle turtle + parent turtle is performed to narrow down the combinations. However, there is a possibility that the combination that satisfies the condition becomes 0 on the way. It is. The combination of U = U1 + 1 can be dealt with by leaving it as a determination target.

  Next, for the combination of U and V (small tortoise + medium tortoise), U = U1 is fixed, and V (however, V ≧ U1. The size of the heel support side is equal to or larger than the size of the supported side) in ascending order. The condition is determined, and the first combination V found is V1. Then, only the combination of V = V1 or V1 + 1 is left as a subsequent determination target among the combinations of U and V of U = U1.

  The same processing is performed for U = U1 + 1. In that case, V of the combination found first is set to V2. Then, only the combination of V = V2 or V2 + 1 is left as a subsequent determination target from the combination of U and V of U = U1.

  In this way, the process is advanced to the combination of U, V, and W (small tortoise + middle tortoise + parent tortoise), and the final remaining combination of U, V, and W becomes the output of the narrowing-down means 21. When the remaining number is large, it is preferable to narrow down to a predetermined number from the younger number. The reason is that the younger number is cheaper and meets the needs of Web visitors 13.

  In the product sales method using the Web shown in FIG. 25, in S80, the Web visitor 13 inputs a design specification for a plurality of specification items of the product (eg, 3-axis actuator) to the Web visitor 13 (example). : FIG. 5 to FIG. 10) are presented.

  In S81, a combination of a plurality of parts (for example, x-axis related parts, y-axis related parts, and z-axis related parts) constituting a product satisfying the design specifications is taken into account in the sales or technical experience of the product seller. We narrow down by narrowing down method.

  In S82, the Web visitor 13 takes into account the sales or technical experience of the seller as an index (eg, safety factor and travel life) when selecting a desired combination from the narrowed down combinations. Calculation is performed based on the data and design specifications of each component of each combination using an index calculation formula.

  In S83, a Web screen including a plurality of combinations narrowed down by the narrowing-down method and an index for each combination is presented to the Web visitor 13.

  Steps S80, S81, S82, and S83 implement processes corresponding to the functions of the input screen presenting means 20, the narrowing means 21, the calculating means 22, and the combination presenting means 23 in FIG. Therefore, the specific functions described above with respect to the input screen presenting means 20, the narrowing means 21, the calculating means 22, and the combination presenting means 23 in FIG. 1 can be directly applied as the specific processes of S80, S81, S82, and S83. .
