Description

  The present invention relates to a production management apparatus for an injection molding machine that is suitable for use when displaying a count value of non-defective / defective products in a produced molded product.

  In general, since mass production is often performed in production operations of plastic products (molded products) using an injection molding machine, production management for accurately grasping the production quantity is important. In particular, in the case of molded products, defective products based on molding defects occur in addition to non-defective products, and the boundary between the non-defective products and the defective products, that is, it is not easy to determine whether the molded product is good or not, and production management for the good / defective products is complicated. Easy to convert. For this reason, in the field of injection molding machines, various production management methods have been proposed from the viewpoint of improving the accuracy or ease of production management.

  Conventionally, as such a production management method, a production management system disclosed in Patent Document 1, a data processing method disclosed in Patent Document 2, and a molding system disclosed in Patent Document 3 are known.

  The production management system disclosed in Patent Document 1 includes a setting unit for inputting the number of shots scheduled to be produced, a subtraction counter for subtracting 1 each time one shot is formed from the number of shots to be produced, and how many shots before production end A production end notice signal output shot number setting unit for determining whether to output an end notice signal, and a comparison unit for comparing the value of the subtraction counter with the value of the number of shots for production end notice signal output. Is configured to output a production end notice signal when it is equal to or smaller than the number of shots for production end notice signal output.

  Further, the data processing method of the molding machine disclosed in Patent Document 2 eliminates unnecessary production, improves productivity and economy, contributes to material saving and energy saving, and efficiently manages data. The purpose is to quickly obtain accurate tabulation data, etc., and specifically, it is attached to the molding machine main body when processing the molding data accompanying molding from the molding machine controller provided in the molding machine main body. The take-out data accompanying the take-out of the molded product obtained from the take-out device controller provided in the molded product take-out device is transmitted to the molding machine controller, and at least the molding data is corrected by the take-out data.

  Furthermore, the molding system disclosed in Patent Document 3 aims to obtain a molding system that performs production management based on the number of molded products collected by a molded product collection device, and that can be managed easily, inexpensively, and with good operability. Specifically, a production management function is incorporated in the PLC of the control device of the injection molding machine, and it is confirmed that the molded product has been normally recovered in the PLC of the molded product recovery device. The product collection completion signal is sent to the injection molding machine controller, and the PLC of the injection molding machine controller counts this molded product collection completion signal with a counter, and sends a conveyor feed signal every time the set container capacity is reached. Then, the container is replaced with a new one, and the molding is stopped when the count value reaches the set total production number.

  However, the conventional production management methods disclosed in Patent Documents 1 to 3 described above also have the following problems to be solved.

  In other words, the good / defective product of the molded product is usually discriminated by a pass / fail discrimination process on the molding machine side, and this discrimination signal is transmitted to the molded product take-out machine, which is a peripheral device. Finally, the operator checks the appearance of the molded product and confirms the non-defective product / defective product.

  On the other hand, as an initial setting item related to production management, it is essential to set the planned number of production. However, if a non-defective product / defective product occurs that is different from the pass / fail judgment process on the molding machine side during production, the final production plan It is necessary to increase the number corresponding to the number of defective products, and the number of defective products is usually reset. However, the number of defective products includes the check results by the above-mentioned operator, so production is scheduled. The number cannot be reset automatically.

  Therefore, the scheduled production number is reset by the operator's manual input. At this time, if an input error occurs by the operator, there is a problem that the molding machine stops operating. That is, when it is determined that the molding machine controller has reached the planned production number with respect to a numerical value erroneously input by the operator, the molding machine stops operating at that time. Eventually, when such a situation occurs, the production must be interrupted unnecessarily, resulting in an adverse effect on the molded product due to the interruption, and a reduction factor that cannot be ignored.

  Moreover, the pass / fail judgment result on the molding machine side is reflected in the non-defective product counter and the defective product counter, and the number of non-defective / defective products is displayed. However, when the final confirmation is made by the operator, the number of good / defective products is changed. In reality, the good product counter and the defective product counter cannot be easily changed from the viewpoint of security or the like.

  Thus, in actual production management in an injection molding machine, the count is likely to fluctuate, and miscounts and input errors are likely to occur. Eventually, production management tends to be complicated, and there is room for further improvement from the viewpoint of ensuring the accuracy and certainty of production management, and further ease.

  An object of the present invention is to provide a production management device for an injection molding machine that solves the problems existing in the background art.

Accurately set and manage the quantity of molded products. Therefore, it is not necessary to reset the planned production quantity set as the initial setting item, so there is a problem that occurs when the planned production quantity is reset by mistake, that is, adverse effects on the molded product due to unnecessary interruption of production and production efficiency. Can be eliminated.

  (2) Correction selection means Rc that can select whether to permit correction of the non-defective product count value Np and / or the defective product count value Nn, and input on the correction input screen Vi is permitted by the selection of correction permission by the correction selection means Rc.

Receive.

  The molding machine controller 3 having such a basic configuration includes the following configuration (means, function) as the production management apparatus 1 according to the present embodiment.

  First, the display 2 has a function of displaying the production management screen Vc shown in FIGS. Note that the production management screen Vc shown in FIG. 3 mainly shows only the part related to the production management apparatus 1 according to the present embodiment.

  In the display elements of the production management screen Vc, Km is a correction selection key, which constitutes the correction selection means Rc. The correction selection key Km is normally in the OFF position, but can be switched to the ON position by touch. At the ON position, correction of a non-defective product count value Np and a defective product count value Nn described later is permitted. In other words, the modification permission can be selected by the modification selection key Km. If the correction selection key Km displayed on the production management screen Vc is used as the correction selection means Rc, the correction selection key Km can be turned on in the state displayed on the production management screen Vc, so that the correction permission can be easily selected. There are advantages.

  When the correction selection key Km is turned ON, the correction input screen Vi shown in FIG. 1 can be displayed on the production management screen Vc (display 2) as a window. That is, input on the correction input screen Vi is permitted, and the non-defective product correction value Npm and the defective product correction value Nnm used for correction can be input. This correction input screen Vi constitutes correction input means Ri. If such a correction input means Ri is provided, the correction input screen Vi displayed as a separate screen can be used, so that the non-defective product correction value Npm and the defective product correction value Nnm are erroneously input on the production management screen Vc. There is an advantage that mistakes can be avoided, reliable and easy input can be realized, and correct correction (resetting) can be performed together with information on the production management screen Vc.

  On this correction input screen Vi, a non-defective product correction value display unit 31 for displaying a non-defective product correction value Npm for correcting a non-defective product count value Np based on a non-defective product counter function Fmp for counting non-defective products, which will be described later, A defective product correction value display unit 32 for displaying a defective product correction value Nnm for correcting the defective product count value Nn based on the non-defective product counter function Fmn, and an increase / decrease for setting the good product correction value Npm and the defective product correction value Nnm A key part Ki is provided. The increase / decrease key part Ki has four keys Kpu..., That is, a “+” key Kpu that increases the non-defective product correction value Npm, a “−” key Kpd that decreases the non-defective product correction value Npm, and an increase of the defective product correction value Nnm. A “+” key Knu and a “−” key Knd for reducing the defective product correction value Nnm are provided.

  The initial screens of the non-defective product correction value display unit 31 and the defective product correction value display unit 32 are in a reset state and “0” is displayed. However, when the non-defective product correction value display unit 31 is touched, the numeric keypad input screen is displayed. Can be displayed. Thus, the non-defective product correction value Npm can be input using this numeric keypad input screen. Further, when the input non-defective product correction value Npm is used in the direction of increasing, the “+” key Kpu is touched, whereby an enter key is displayed. Therefore, the non-defective product correction value to be added by touching the enter key is displayed. The input can be confirmed as Npm. On the other hand, in the case where the input non-defective product correction value Npm is used in the direction of decreasing, the “−” key Kpd is touched. As a result, the enter key is displayed. By touching the enter key, the input can be confirmed as the non-defective product correction value Npm to be subtracted. Although the non-defective product correction value display unit 31 has been described above, the defective product correction value Nnm can be similarly input to the defective product correction value display unit 32.

  On the other hand, if the input of the non-defective product correction value Npm and the defective product correction value Nnm is determined by touching the enter key, the correction processing of the non-defective product count value Np and the defective product count value Nn is performed by the data correction processing means Rm. Specifically, the non-defective product correction value Npm and the defective product correction value Nnm are reflected in the non-defective product counter function Fmp and the defective product counter function Fmn, respectively. The non-defective product count value Nn is corrected. That is, the non-defective product correction value Npm is added to or subtracted from the non-defective product count value Np, and the defective product correction value Nnm is added to or subtracted from the defective product count value Nn.

  As a result, the display of the non-defective product count value Np displayed on the non-defective product number display unit 47 described later is changed to a new non-defective product count value Np corrected by the non-defective product correction value Npm and displayed on the defective product number display unit 48. The displayed defective product count value Nn is changed to a new defective product count value Np corrected by the defective product correction value Nnm.

  The increase / decrease key part Ki can be used in other ways, and can be used as a normal up / down key. That is, a numerical value obtained by adding “1” can be displayed by touching the “+” key Kpu... And a numerical value obtained by subtracting “1” by touching the “−” key Kpd. Display can be made. Then, by touching the close button 33 (or the end key), the correction input screen Vi can be closed and the input can be confirmed.

  Further, the production management screen Vc includes a switching key 42 for switching ON / OFF of the counter function, a scheduled production number setting unit 43 for setting the planned production number, a planned input number setting unit 44 for setting the planned production number, an input A switching key 45 for switching ON / OFF of the number completion alarm is provided, and a count value display unit 46 for displaying a count value is provided. The count value display unit 46 counts the non-defective product number display unit 47 for displaying a non-defective product count value Np based on the non-defective product counter function Fmp for counting the number of non-defective products in the produced molded product. Defective product count display section 48 that displays a defective product count value Nn based on the defective product counter function Fmn, a product quantity display portion 49 that displays the number of products received, and a non-defective product shot number that displays the count value of the number of shots obtained. The display unit 50 includes a defective shot number display unit 51 that displays a count value of the number of shots that have become defective, and a shot number display unit 52 that displays the number of shots received. In addition, a non-defective shot number display unit 53 that displays the number of shots including a non-defective product and a defective product, an image display unit 41 that indicates the production progress in percentage, and a clear that clears (resets) the non-defective product count value Np and the defective product count value Nn. A key 54 and a number clear key 55 for clearing (resetting) the number display are provided.

  Further, the molding machine controller 3 includes at least a quality determination function Fc, a production management function Fm, and a production data display function Fd as shown in FIG. 2 in order to realize the production management apparatus 1 according to the present embodiment. . The example quality determination function Fc is determined based on the magnitude or change state of the physical quantity related to the operation state of the molding process. That is, normally, since the magnitude and change state of the physical quantity related to the operation state of the molding process are monitored as trend data, if each trend data is within the preset discrimination threshold, it is judged as non-defective and the discrimination threshold If it is off, it is judged as a defective product. Since the control signal (discrimination signal) based on the discrimination result is transmitted to the take-out machine controller 61, the molded product take-out machine 60 distributes the molded product to a good product shooter or a defective product shooter according to the discrimination signal. Can do.

  The production management function Fm includes at least a non-defective product counter function Fmp for counting the number of good products and a defective product counter function Fmn for counting the number of defective products in the produced molded product. For the good product counter function Fmp and the defective product counter function Fmn, the determination result of the good / bad determination function Fc described above can be used. That is, the discrimination signal obtained by the pass / fail discrimination function Fc is directly used, and in the case of a non-defective product, counting is performed by the non-defective product counter function Fmp, and in the case of a defective product, counting is performed by the defective product counter function Fmn. In addition, although the example using the discrimination signal of the pass / fail discrimination function Fc was given, other various discrimination functions can be used. Normally, normal or abnormal (non-normal) monitoring is performed in each step of the molding process, and determination is performed based on these monitoring results, and a final determination signal including these determination results is output to the unloader controller. 61 may be sent. Therefore, the final determination signal received from the unloader controller 61 may be used for the non-defective / defective product count.

  The production data display function Fd is a function for displaying the non-defective product count value Np based on the non-defective product counter function Fmp and the defective product count value Nn based on the defective product counter function Fmn on the production management screen Vc of the display 2. In the case of the example, it is displayed on the count value display unit 46 described above. That is, the non-defective product count value Np based on the non-defective product counter function Fmp is displayed on the non-defective product number display unit 47, and the defective product count value Nn based on the defective product counter function Fmn is displayed on the defective product number display unit 48.

  In addition, the molding machine controller 3 is provided with data storage means Rr for storing the non-defective product correction value Npm and the defective product correction value Nnm as history data. The data storage means Rr includes a controller main body 21 and an internal memory 22. Can be used. As described above, if the production management device 1 is provided with the data storage means Rr for storing the non-defective product correction value Npm and the defective product correction value Nnm as history data, the magnitude and the correction timing of the non-defective product correction value Npm and the defective product correction value Nnm. Thus, there is an advantage that it can be effectively used as production information in analyzing the occurrence status of defective products.

  Next, the usage method and function of the production management apparatus 1 according to the present embodiment will be described with reference to FIGS.

  FIG. 4 shows a flowchart for explaining a method of correcting the count value using the production management apparatus 1, and FIG. 5 is a flowchart more specifically showing the processing procedure of the correction processing step in the flowchart shown in FIG. Show. Hereinafter, according to each flowchart, the usage method of the production management apparatus 1 including the correction method of a count value is demonstrated.

  First, a production plan for production is set (step S1). In this case, the display 2 displays the production management screen Vc shown in FIG. First, the production schedule number is set in the production schedule number setting unit 43. In this case, if the production schedule number setting unit 43 is touched, a numeric keypad input screen is displayed. Using this numeric keypad input screen, it is possible to input a target production schedule quantity (illustration is “10000”). . Other necessary settings, for example, ON / OFF switching of the counter function by the switching key 42, setting of the planned number of incoming numbers by the predetermined number setting unit 44, ON / OFF switching of the completion number warning by the switching key 45, etc. Make the necessary settings (selection). The non-defective product number display portion 47 and the defective product number display portion 48 are both displayed with “0” reset.

  When the setting of the production plan is completed, the production is started by turning on a predetermined start button (step S2). Thereby, for example, the production operation in the automatic mode is performed (step S3). In the production operation, a molding cycle (molding process) based on the sequence control of the molding machine controller 3 is executed to produce a molded product, and the molded product is taken out by the molded product take-out machine 60. In addition, during production operation, a quality determination process by the quality determination function Fc is performed on the molded product (step S4). In the example, since the pass / fail judgment function Fc of the molding machine controller 3 is used, a judgment signal (control signal) based on the pass / fail judgment function Fc is transmitted to the unloader controller 61, and the non-defective product or the defective product is sorted at the time of take-out. At the same time, this determination signal is reflected (supplied) in the production management function Fm, particularly in the non-defective product counter function Fmp and the defective product counter function Fmn.

  In this case, if a discrimination signal related to a non-defective product is supplied, “1” is added to the non-defective product count value Np by the non-defective product counter function Fmp (steps S5 and S6). The good product count value Np is displayed on the good product number display section 47 in real time (step S7). On the other hand, if a determination signal related to a defective product is supplied, “1” is added to the defective product count value Nn by the defective product counter function Fmn (steps S5 and S8). The defective product count value Nn is displayed on the defective product display 48 in real time (step S9).

  On the other hand, when a predetermined amount of production is performed, the operator confirms final quality such as an appearance check on the molded product. At this time, even if it is a defective product, it may be changed to a non-defective product, or even if it is a non-defective product, it may be changed to a defective product. Therefore, the operator uses the function of the production management device 1 according to the present embodiment to The count value Np and the defective product count value Nn can be corrected (steps S10 and S11).

  Hereinafter, this correction method will be described with reference to the flowchart shown in FIG. When correcting, first, the correction selection key Km shown in FIG. 3 is touched and switched to ON (step S111). Thereby, the correction input screen Vi shown in FIG. 1 is displayed in a window on the production management screen Vc (step S112). That is, since the input on the correction input screen Vi is permitted, the non-defective product correction value Npm and the defective product correction value Nnm used for the correction can be input. In the initial screen of the correction input screen Vi, both the non-defective product correction value display unit 31 and the defective product correction value display unit 32 are reset to “0”.

  When the good product count value Np is corrected, the good product correction value display unit 31 is touched. As a result, a numeric keypad input screen is displayed, and the non-defective product correction value Npm is input using the numeric keypad input screen. FIG. 1 shows a case where “18” is input. The operator checks whether or not the non-defective product correction value Npm is correct, and touches the “+” key Kpu to increase the non-defective product count value Np. Thus, since the enter key is displayed, the input is confirmed by touching the displayed enter key. On the other hand, in order to reduce the non-defective product count value Np, the “−” key Kpd is touched. Thus, since the enter key is displayed, the input key is touched to confirm the input (steps S113, S114, S115). As a result, the non-defective product correction value Npm is reflected in the non-defective product counter function Fmp. In other words, the non-defective product correction value Npm is added to or subtracted from the non-defective product count value Np by the data correction processing means Rm, thereby correcting the new good product count value Np. Then, the corrected new product count value Np is displayed on the non-defective product display portion 47.

  When the defective product count value Nn is corrected, the defective product correction value display unit 32 is touched. As a result, a numeric keypad input screen is displayed, and the defective product correction value Nnm is input using the numeric keypad input screen. FIG. 1 shows a case where “7” is input. The operator checks whether or not the defective product correction value Nnm is correct, and touches the “+” key Knu to increase the defective product count value Nn. Thus, since the enter key is displayed, the input is confirmed by touching the displayed enter key. On the other hand, in order to reduce the defective product count value Nn, the “−” key Knd is touched. Thus, since the enter key is displayed, the input key is touched to confirm the input (steps S116, S117, S118). As a result, the defective product correction value Nnm is reflected in the defective product counter function Fmn. That is, the defective product correction value Nnm is added to or subtracted from the defective product count value Nn by the data correction processing means Rm, so that the new defective product count value Nn is corrected. Then, the new defective product count value Nn corrected is displayed in the defective product number display section 47. In addition, although the case where both the non-defective product count value Np and the defective product correction value Nnm are corrected is shown, the correction can be performed by only one of them.

  As described above, the correction using the non-defective product correction value Npm and the defective product correction value Nnm is completed, so that the operator touches the close button 33 and closes the correction input screen Vi. Thereby, the correction process ends (step S119). By closing the correction input screen Vi, the non-defective product correction value Npm and the defective product correction value Nnm on the correction input screen Vi are reset. At this time, along with the correction processing of the non-defective product count value Np and the defective product count value Nn by the non-defective product correction value Npm and the defective product correction value Nnm, if there are other related correction portions, the correction is performed simultaneously. However, the planned production number displayed on the production planned number setting unit 43 is not changed. Furthermore, data relating to the non-defective product correction value Npm and the defective product correction value Nnm is stored as history data by the data storage means Rr. On the other hand, if the production operation progresses and the target number of productions is reached, a production end process is performed to end the production (steps S12 and S13). Note that the production end process includes a purge process and the like.

  Therefore, according to the production management apparatus 1 according to the present embodiment, a correction input screen that is a separate screen with respect to the production management screen Vc by selecting correction permission for the non-defective product count value Np and / or the defective product count value Nn. The non-defective product count value Np and / or the non-defective product count value Nn is obtained by adding or subtracting the non-defective product correction value Npm and / or the defective product correction value Nnm that is input to the correction input screen Vi and is confirmed. Since the correction is made, it is possible to accurately set and manage the quantity of molded products that finally become non-defective / defective products. Therefore, it is not necessary to reset the planned production quantity set as the initial setting item, so there is a problem that occurs when the planned production quantity is reset by mistake, that is, adverse effects on the molded product due to unnecessary interruption of production and production efficiency. Can be eliminated.

  In addition, the correction selection means Rc that can select the correction permission of the non-defective product count value Np and / or the defective product count value Nn, and the correction that becomes a separate screen with respect to the production management screen Vc by selecting the correction permission by the correction selection means Rc. The correction input means Ri that allows the input on the input screen Vi and allows the input of the non-defective product correction value Npm and / or the defective product correction value Nnm used for the correction, and the non-defective product correction value that is input to the correction input screen Vi and confirmed. Npm and / or defective product correction value Nnm is reflected in at least the non-defective product counter function Fp and / or defective product counter function Fn, and the non-defective product count value Np and / or defective product is determined by the non-defective product correction value Npm and / or defective product correction value Nnm. Since the data correction processing means Rm for correcting the count value Nn is provided, the operator finally checks the appearance of the molded product, Even if there is a change in the quantity of non-defective / defective products by checking the non-defective product / defective product, use the correction input screen Vi for inputting the non-defective product correction value Npm and the defective product correction value Nnm. The operator can confirm the non-defective product correction value Npm and the defective product correction value Nnm once on the correction input screen Vi before performing the change setting. As a result, it is possible to avoid an input error by the operator, and to contribute to improvement of accuracy, certainty and ease of production management.

  The preferred embodiment has been described in detail above, but the present invention is not limited to such an embodiment, and the detailed configuration, shape, quantity, numerical value, method, and the like do not depart from the gist of the present invention. It can be changed, added, or deleted arbitrarily.

  For example, in the exemplary embodiment, the case where both the non-defective product counter function Fmp and the defective product counter function Fmn are provided has been described. However, the case where the product is applied to only one of the functions is not excluded. In addition, the production management screen Vc in the present invention is not only a screen for comprehensively managing production as illustrated, but also a screen for displaying only the non-defective product number display section 47 and / or the defective product number display section 48 or other display screens. It is a concept including the case where it is displayed on a part of the screen.

  The production management apparatus according to the present invention can be used for various injection molding machines including a display for displaying a non-defective product count value / defective product count value in a produced molded product.
