Description

  The present invention relates to a molded product take-out machine configured to automatically perform setup change when shifting to taking out a molded product different from a current molded product.

  The molded product take-out machine is a machine tool for taking out a product (hereinafter referred to as “molded product”) molded by a molding machine such as injection molding or extrusion molding. When taking out a wide variety of molded products with a single molded product take-out machine, it is necessary to replace the chuck part corresponding to each molded product or adjust the molding machine.

Conventionally, an example of a technique has been disclosed in which various data relating to a take-out operation are stored and corresponding data can be set when an operator displays a menu screen and selects an operation mode (see, for example, Patent Document 1). . When this technology is applied to setup change, a data file with a unique code is stored for each setup change, and an operator can select and set a data file corresponding to the code from the menu screen. It becomes possible.
JP 2003-256498 A

However, there is a problem that even if the operator does not know how to call the menu screen or knows how to call the menu screen, the code is erroneously set.
The present invention has been made in view of these points, and an object of the present invention is to provide a molded product take-out machine that can be set even by an inexperienced operator and that can reduce setting errors as compared with the prior art.

(1) Means for solving the problem (hereinafter, simply referred to as “solution means”) 1 is specific to each set-up with respect to the set-up to be performed when shifting to taking out a molded product different from the current molded product. A molded product take-out machine comprising a storage means for storing a data file with a reference numeral and a control means for controlling the changeover according to the changeover data described in the set data file. Information reading means for reading code information recorded on a medium, code acquisition means for acquiring a code based on the code information read by the information reading means, and a data file to which the code acquired by the code acquisition means is attached And a data setting means for loading and setting from the storage means.

  Recording media include card members (cards with codes and characters, cards capable of magnetic recording, cards with ICs, etc.), transfer members (chuck units, hands, etc.), recording disks (magnetic disks and optical disks). Magnetic disk), portable storage devices (memory stick, SD card, etc.). Code information includes graphics (including patterns), characters, symbols, and the like. The form of the code information recorded on the recording medium is arbitrary as long as it can be read by the information reading means, and includes, for example, description, printing, sticking, magnetic recording (including magneto-optical recording), engraving, unevenness, and perforation. The information reading means corresponds to a code reader, an imaging device, a magnetic head (including a magneto-optical head), and the like. A character, a symbol, etc. correspond to a code | symbol.

  According to the solving means 1, the operator only needs to read the recording medium by the information reading means, the code obtaining means obtains the code, and the data setting means sets the data file corresponding to the code. Therefore, even an inexperienced operator can make a setting with certainty, and setting errors can be reduced as compared with the conventional case.

(2) The solution means 2 is the molded product take-out machine described in the solution means 1 and includes a code reader as information reading means, and the code acquisition means acquires a code based on the barcode read by the code reader. The gist is that it is configured.

  According to the solution means 2, the operator only needs to read the barcode with a code reader, the code acquisition means acquires the code, and the data setting means sets the data file corresponding to the code. Since the code reader is inexpensive and the cost of recording a barcode is low, the overall cost can be kept low.

(3) The solution means 3 is a molded product take-out machine described in the solution means 1, and includes a card member as a recording medium and an imaging device as an information reading means, and the code acquisition means includes the card member. The gist is that a code or a character included in an image signal captured by the imaging device is recognized, and a code is acquired based on the recognized code or character.

  According to the solution means 3, the operator only needs to image the card member with an imaging device (for example, a CCD camera), the code acquisition means acquires the code, and the data setting means sets the data file corresponding to the code. . The card member can be used as a single unit, or can be provided in a chuck portion, a mold, or the like. A data file can be set by capturing an image of a card member provided in a chuck portion, a mold, or the like to be transferred by setup change. Therefore, since the relationship between the chuck portion, the mold, and the like and the card member is clear, setting errors can be further reduced as compared with the related art.

(4) The solution means 4 is the molded product take-out machine described in the solution means 1, and includes a chuck portion as a recording medium, a detector for detecting the position of the chuck portion, and an imaging device as an information reading means. The code acquisition means, when the position of the chuck portion detected by the detector is within a predetermined range, extracts code information included in the image signal of the chuck portion imaged by the imaging device; The gist is that the code is obtained by recognizing the extracted code information.

  According to the solution means 4, it is necessary to replace the chuck portion at the time of setup change, and a code or a character is recorded in the chuck portion in advance. When the detector detects that the position of the chuck portion is within a predetermined range, the imaging device images the chuck portion, the code acquisition means extracts and recognizes the code information to acquire the code, and the data corresponding to the code The data setting means sets the file. Since the operator only needs to replace the target chuck portion, the data file can be set reliably, and setting errors can be reduced as compared with the conventional case.

(5) The solution means 5 is the molded article take-out machine described in any one of the solution means 1 to 4, and when the data file that matches the code acquired by the code acquisition means is not stored in the storage means A data search means for searching for a data file with a code that partially matches the code, and a code attached to the data file searched by the data search means is displayed on the display, Code selection means for selecting one of the displayed codes, and the data setting means loads and sets a data file to which the code selected by the code selection means is attached from the storage means The gist is that it is configured.

  The recording medium is not always perfect, and part of the code information may be damaged (for example, soiled or missing) as it is used. In such a case, even if the code is acquired by the code acquisition unit, the data file cannot be set because it does not match the code of the data file stored in the storage unit. According to the solution means 5, the data file with the code partially matching the code acquired by the code acquisition means is searched, and the searched code is displayed on the display unit. What is necessary is just to select a code | symbol. Therefore, even if the code information is incomplete, a data file can be set without requiring a new recording medium.

(6) The solution means 6 is the molded product take-out machine described in any one of the solution means 1 to 5, and the storage device has a setup change corresponding to the unique code assigned to each data file. A first display form for storing a name and displaying a setup change name corresponding to the data file set by the data setting means on the display, and a setup change name corresponding to the data file selected by the code selection means The gist of the present invention is to have name display means for performing one or both of the second display forms displayed on the screen.

  According to the solution 6, since the code corresponds to the setup change name, the operator can determine the suitability by the setup change name even when the contents of the code are not completely remembered. As described above, since the suitability can be determined based on the setup change name displayed in the first display form or the second display form, the setting error can be further reduced as compared with the conventional case.

  According to the present invention, even an inexperienced operator can make a setting reliably, and setting errors can be reduced as compared with the prior art.

  The best mode for carrying out the present invention will be described with reference to the drawings.

  The drive devices 42, 44, and 46 operate according to the control signal, and the chuck portion 48 moves as indicated by an arrow D4 indicated by a broken line, for example. By this operation, the molded product P remaining in the movable mold 35 after the mold opening can be gripped and taken out by the chuck portion 48 and transferred to the storage box 51 placed on the transport device 50 for storage.

  2 includes a storage unit M, a code acquisition unit 23, a data setting unit 24, a control unit 25, a data search unit 26, a code selection unit 27, a name display unit 28, a display 29, and the like. Have. Specifically, for example, a CPU, a ROM, a RAM, an input / output circuit, and the like are included. Among these means, the code acquisition means 23, the data setting means 24, the data search means 26, the code selection means 27, and the name display means 28 are realized by executing a setup change process described later. For example, a liquid crystal display is applied to the display 29, but a plasma display, an LED display, a CRT, or the like may be applied.

  The storage means M corresponds to the ROM, RAM, disk device or the like, and stores a data file F to which a unique code is added for each setup change, other data or a working file. The code acquisition unit 23 acquires a code based on the barcode (corresponding to code information) read by the code reader 22a (corresponding to the information reading unit 22). The data setting unit 24 loads and sets the data file F with the code acquired by the code acquisition unit 23 from the storage unit M. The control means 25 controls the various operations by transmitting control signals to the setup change mechanism 10, the injection molding mechanism 30, the molded product removal mechanism 40, and the like.

  When the data file F that matches the code acquired by the code acquisition unit 23 is not stored in the storage unit M, the data search unit 26 selects the data file F with the code partially matching the acquired code. Search from storage means M. The code selection means 27 displays the code attached to the data file F searched by the data search means 26 on the display 29, and the operator selects one code from the codes displayed on the display 29. . The name display means 28 performs one or both of the first display form and the second display form for displaying the setup change name on the display device 29. In the first display form, the name of the setup change corresponding to the data file F set by the data setting means 24 is displayed. In the second display form, the setup change name corresponding to the data file F selected by the code selection means 27 is displayed.

  The control device 20 configured as described above executes a setup change process when the setup change is performed. A procedure example of the setup change process will be described with reference to FIG. This setup change process is repeatedly performed as long as the control device 20 is powered on.

  First, the barcode reader 22a attempts to read the barcode [Step S11]. If the code reader 22a cannot read the bar code because it is not used or the like (NO in step S12), the process is terminated without changing the setup. On the other hand, when the operator reads a barcode recorded on the card member 21 as shown in FIG. 4 using the code reader 22a (YES in step S12), steps S13 to S20 are performed. Run until. The card member 21 corresponds to a recording medium, and for example, a paper card is applied.

  In the recording example of the card member 21 shown in FIG. 4, a setup change number 21a, a setup change name 21b, and a barcode 21c are recorded. In this example, “1234-5670” is recorded as the setup change number 21a, “A company plastic bottle body” is recorded as the setup change name 21b, and “1234-5670” of the setup change number 21a is recorded on the barcode 21c. A graphic (striped pattern) corresponding to is recorded. It should be noted that characters such as “setup number” and “setup name” may be recorded or not. The setup change number 21a and the setup change name 21b are used when the operator selects the card member 21, and the bar code 21c is used for reading by the code reader 22a. Such a card member 21 is prepared for each setup change, and the contents of the setup change number 21a, the setup change name 21b, and the barcode 21c corresponding to the type of setup change are recorded and stored in the storage means M.

  Returning to FIG. 3, the code is acquired from the barcode read in step S11 [step S13], and the data file F to which the code matching the code acquired in step S13 is attached is searched from the storage means M [step S14. ].

  In the structure example of the data file F shown in FIG. 5, the setup change number Fa, the setup change name Fb, the mold number Fc, the chuck part number Fd, the molding material number Fe, the mold operation number Ff, the removal operation number Fg, and others. It is composed of data. The contents recorded in the data file F in this way correspond to “setup data”.

  In this example, “1234-5678” is stored in the setup change number Fa used for the code search, and “A company plastic bottle body” is stored in the setup change name Fb used in the list display. “A123” is stored in the mold number Fc specifying the mold to be performed, “B45” is stored in the chuck part number Fd specifying the chuck part to be replaced, and the molding material number specifying the raw material of the molded product P “66-789” is stored in Fe, “C-321” is stored in the mold operation number Ff for specifying the operation of the mold at the time of molding, and the operation number for extracting the molded product P is specified. “D87654” is stored in Fg. Such a data file F is also prepared for each setup change, and the contents of the setup change number 21a, the setup change name 21b, and the barcode 21c corresponding to the type of setup change are recorded and stored in the storage means M. . Furthermore, operation data specified by the mold operation number Ff and the removal operation number Fg is also stored in the storage means M.

  Returning again to FIG. 3, if the target data file F is found (YES in step S15), the retrieved data file F is loaded from the storage means M and set [step S19]. In order to notify what kind of content has been set, for example, it is displayed in the first display form as shown in FIG. In the example of FIG. 6, a setup change number 29a, a setup table 29b, and the like are displayed. The setup change number 29a is the code acquired in step S13. The setup table 29b is the contents of the set data file F. In this example, the data of the setup change number Fa, the setup change name Fb, the mold number Fc, the chuck part number Fd, the molding material number Fe, the mold operation number Ff, and the removal operation number Fg shown in FIG. It is displayed. Therefore, the operator can grasp the data contents of the setup change.

Then, according to the contents of the data file F set in step S19, a control signal is transmitted to the setup change mechanism 10, the molded product take-out mechanism 40, etc. to perform setup change [step S20]. In this setup change, molds are exchanged and molding conditions are set. For example, the robot apparatus 12 stores the currently installed movable mold 35, immovable mold 34, chuck portion 48, etc. in the storage 11, and according to the contents of the data file F, the movable mold 35 corresponding to the next molding, The stationary mold 34, the chuck portion 48, etc. are attached to the corresponding parts (see FIG. 1).
After the setup change, the control means 25 transmits control signals to the injection molding mechanism 30 and the molded product take-out mechanism 40 to produce and carry out the molded product.

  On the other hand, if the target data file F is not found (NO in step S15), a data file F partially matching the code acquired in step S13 is searched from the storage means M [step S16]. Then, the information of the retrieved data file F is displayed on the display 29, and the operator is made to select one data file [step S17]. When the operator selects one data file (YES in step S18), the control signal is transmitted to the setup change mechanism 10, the molded product take-out mechanism 40, etc. according to the contents of the selected data file F, and the setup change is performed. Perform [Step S20]. If the target data file F is not found in step S16, or if there is no data file F that can be selected by the operator in step S17 (NO in step S18), the setup is changed. Finish the process without

  Here, a case where the target data file F is not found by the search in step S14 will be described. For example, like the card member 21 shown in FIG. 7, it is a case which has the fouling part 21d for some reason (for example, adhesion of oil, secular change, etc.). Even if the card member 21 of FIG. 7 is read by the code reader 22a with the barcode 21c, only the code “1234-56” can be obtained. Therefore, in step S16, the data file F having a part of the code “1234-56” is searched from the storage means M, and the result is displayed on the display 29 in the second display form.

  An example of the second display form displayed on the display 29 is shown in FIG. In the example of FIG. 8, a reading number 29c, a list 29d, a selection button 29e, a cancel button 29f, and the like are displayed. The reading number 29c is a code that can be acquired in step S13, and a portion that cannot be acquired is indicated by “*”. The list 29d displays information related to the data file F that can be searched in step S16. In this example, the part change information Fa shown in FIG. 5 is displayed in the left column and part of the information related to the four data files F having the code “1234-56” in part, and the middle column in FIG. The represented changeover name Fb is displayed.

The right column of the list 29d is a check column for selection, and the operator can specify one data file F with a check “re” using a selection member (eg, button, mouse, keyboard, etc.). When the selection button 29e is operated, the selection of the data file F checked in the right column (check column) of the list 29d is confirmed. When the cancel button 29f is operated, the check in the right column of the list 29d is ignored and the non-selection of the data file F is confirmed. Step S18 is determined by such selection / non-selection of the data file F.
On the other hand, when there is no data file F including the corresponding code in the search in step S16, no information is displayed in the list 29d. Therefore, the non-selection of the data file F is confirmed regardless of which of the selection button 29e and the cancel button 29f is operated.

In the example described above, the card member 21 has the fouling part 21d (see FIG. 7), but the same processing is performed when there is other damage (steps S16 and S17 in FIG. 3). Other damages include, for example, loss, breakage, burnout, loss, breakage, wear, bruise, laceration, and the like, and a case where a part of the barcode 21c cannot be read due to any damage.
In the above-described example of the search in step S16, the data file F is found by the forward match search in which the codes match from the front. However, other search methods (for example, the backward match search in which the codes match from the rear, The data file F may be found by an intermediate match search or the like that matches.

According to Embodiment 1 described above, the following effects can be obtained.
(A1) Storage means M for storing a data file F with a unique code for each setup change, and control means 25 for controlling the setup change according to the setup change data described in the set data file F. And a code reader 22a for reading the barcode 21c recorded on the card member 21 (see FIG. 2). Then, a code is acquired based on the barcode 21c read by the code reader 22a (code acquisition means 23; step S13 in FIG. 3), and the data file F to which the acquired code is attached is loaded from the storage means M. Setting (data setting means 24; step S19 in FIG. 3). The operator only needs to read the card member 21 shown in FIG. 4 by the code reader 22a. The code acquisition unit 23 acquires the code, and the data setting unit 24 sets the data file F corresponding to the code. Therefore, even an inexperienced operator can make a setting reliably, and setting errors can be reduced as compared with the conventional case.

(A2) The operator only needs to read the barcode 21c with the code reader 22a, the code acquisition means 23 acquires the code, and the data setting means 24 sets the data file F corresponding to the code. Since the code reader 22a is inexpensive and the cost for recording the barcode 21c is low, the overall cost can be kept low.

(A3) When the data file F that matches the code acquired by the code acquisition means 23 is not stored in the storage means M, the data file F with the code partially matching the code is searched (data search means 26; Steps S15 and S16 in FIG. 3), the code attached to the retrieved data file F is displayed on the display 29, and one code is selected from the codes displayed on the display 29 (code selection). Means 27; Step S17 in FIG. 3) The data file F to which the selected code is attached is loaded from the storage means M and set (data setting means 24; Step S19 in FIG. 3). Even if a part of the barcode 21c is damaged because the card member 21 has the fouling part 21d, a code that partially coincides with the code acquired from the barcode 21c applied to the part that was not damaged is attached. Since the data file F is automatically retrieved and displayed on the display device 29, the operator may select one code. Therefore, even if the barcode 21c is incomplete, the data file F can be set without requiring a new recording medium.

(A4) The storage means M stores a setup change name Fb corresponding to the setup change number Fa (corresponding to a unique code) assigned to each data file F (see FIG. 5). Further, the name display means 28 displays the setup change name Fb corresponding to the set data file F on the display 29 (first display form; step S19 in FIG. 3), and the stage corresponding to the selected data file F. The replacement name Fb is displayed on the display 29 (second display mode; step S17 in FIG. 3). Since the code and the setup change name Fb correspond to each other, the operator can determine the suitability by the setup change name Fb even if the contents of the code are not completely remembered. Therefore, the operator can determine the suitability based on the setup change name Fb displayed on the display device 29, so that setting errors can be further reduced as compared with the prior art.

[Embodiment 2]
The second embodiment is an example in which the code information recorded on the chuck portion is read to realize the setup change, and will be described with reference to FIGS. FIG. 9 shows a configuration example of the production system. FIG. 10 is a schematic diagram illustrating a configuration example of the control device. FIG. 11 is a flowchart showing a procedure example of the setup change process. In addition, the same code | symbol is attached | subjected to the element same as the element used in Embodiment 1, and description is abbreviate | omitted.

  The configuration example shown in FIG. 9 is an alternative to the configuration example shown in FIG. The difference from the configuration example of FIG. 1 is that an imaging device 22b is provided instead of the code reader 22a, and detectors 42a, 44a, and 46a are newly provided. The imaging device 22b corresponds to the information reading unit 22, and for example, a CCD camera is applied. The detectors 42a, 44a, 46a detect the three-dimensional position of the chuck portion 48 and apply, for example, an encoder. In this example, the detector 42 a is provided in the drive device 42, the detector 44 a is provided in the drive device 44, and the detector 46 a is provided in the drive device 46. As shown in FIG. 10, each of the detectors 42a, 44a, and 46a transmits position information to the control device 20 as a signal. The code acquisition means 23 is configured to recognize a code or character included in the image signal captured by the imaging device 22b and acquire a code based on the recognized code or character.

  A procedure example of the replacement process executed by the control device 20 configured as described above will be described with reference to FIG. The setup change process in FIG. 11 replaces FIG. 3 and is repeatedly executed in the same manner as in the first embodiment.

  Hereinafter, processing contents different from those in FIG. 3 will be described. First, position information signals output from the detectors 42a, 44a, and 46a are input, and the three-dimensional position of the chuck portion 48 is specified [step S30]. If the three-dimensional position of the chuck portion 48 specified in step S30 is not within a predetermined range (for example, within a predetermined range from the position of the chuck portion 48 shown in FIG. 9) (NO in step S31), the setup change is performed. Finish the process without doing it. By specifying the three-dimensional position of the chuck portion 48 in this way, it is possible to prevent wasteful imaging when the imaging device 22b is in a position where the chuck portion 48 cannot be imaged.

  On the other hand, if the three-dimensional position of the chuck portion 48 is within a predetermined range (YES in step S31), the image of the chuck portion 48 is picked up by the imaging device 22b [step S32]. As shown in FIG. 12, a bar code 48a is recorded in advance on each chuck portion 48 at a predetermined portion (lower right corner in this example). Therefore, the chuck portion 48 of this example corresponds to a recording medium.

  Returning to FIG. 11, when the image signal output from the imaging device 22b is received (YES in step S33), the barcode 48a included in the image signal is extracted and the code is recognized [step S34]. The processing after the code is recognized and acquired is the same as in the first embodiment (steps S14 to S20).

According to the second embodiment described above, the following effects can be obtained.
(B1) Detectors 42a, 44a, 46a for detecting the position of the chuck portion 48 and an imaging device 22b as the information reading means 22 are provided (see FIGS. 9 and 10). When the position of the chuck unit 48 detected by the detectors 42a, 44a, 46a is within a predetermined range (step S31 in FIG. 11), the code acquisition unit 23 captures the image signal of the chuck unit 48 imaged by the imaging device 22b. The bar code 48a included in is extracted, and a code is acquired based on the extracted bar code 48a (step S34 in FIG. 11). At the time of setup change, it is necessary to replace the chuck portion 48, but the imaging device 22b images the chuck portion 48 at a predetermined position, and the code acquisition means 23 recognizes the code and automatically sets the data file F. . Therefore, since the operator only needs to replace the target chuck portion 48, the data file F can be set reliably, and setting errors can be reduced as compared with the conventional case.

(B2) Regarding other requirements, configurations, operations, etc., the imaging device 22b images the chuck portion 48 at a predetermined position, and the code acquisition means 23 extracts the barcode 48a of the image signal and recognizes the code. Since it is the same as that of Embodiment 1 except for replacing, the same effect as that of Embodiment 1 can be obtained {see the above-mentioned items (a1) to (a4)}.

[Other Embodiments]
Although the best mode for carrying out the present invention has been described in accordance with the first and second embodiments, the present invention is not limited to the embodiment. In other words, the present invention can be implemented in various forms without departing from the gist of the present invention. For example, the following forms may be realized.

(C1) As the recording medium, the card member 21 is used in the first embodiment, and the chuck portion 48 is used in the second embodiment. As the information reading unit 22, the code reader 22a is used in the first embodiment, and the imaging device 22b is used in the second embodiment. The combination of the recording medium and the information reading means 22 may be implemented by a combination other than these.

  For example, a card member 21 is used as a recording medium, and an imaging device 22b (for example, a CCD camera) is used as the information reading unit 22. In this combination, when the imaging device 22b images the card member 21, the code acquisition unit 23 extracts the barcode 21c included in the image signal of the captured card member 21, recognizes the extracted barcode 21c, and encodes it. To get. Therefore, the operator only needs to image the card member 21 with the imaging device 22b, and the code acquisition means 23 recognizes the code and automatically sets the data file F. Although the card member 21 can be used as a single unit as in the first embodiment, it is provided for each member to be replaced at the time of setup change (for example, any one of the chuck portion 48, the stationary die 34, the movable die 35, etc.). It is also possible. In this way, the data file F can be set by capturing an image of the card member 21 provided in the chuck portion 48, the immovable mold 34, the movable mold 35 and the like to be transferred by the setup change. Therefore, since the relationship between the chuck part 48, the immovable mold 34, the movable mold 35, etc. and the card member 21 is clear, setting errors can be further reduced as compared with the related art.

  Further, the chuck unit 48 is used as a recording medium, and the code reader 22 a is used as the information reading unit 22. In this combination, when the code reader 22a reads the barcode 48a recorded in a predetermined part of the chuck portion 48, the code is acquired from the read barcode 48a. Therefore, the operator only needs to cause the code reader 22a to read a predetermined portion (the lower right corner in this example) of the chuck portion 48 shown in FIG. 12, and the code acquisition means 23 acquires the code and the data corresponding to the code. The data setting unit 24 sets the file F. Therefore, even an inexperienced operator can make a setting reliably, and setting errors can be reduced as compared with the conventional case.

(C2) In Embodiment 1, a paper card is applied to the card member 21. However, a card formed of another material (resin, wood, metal, etc.), a card capable of magnetic recording, or a card equipped with an IC. Etc. may be applied. Further, as a recording medium in place of the card member 21, a recording disk (such as a magnetic disk or a magneto-optical disk), a portable storage device (such as a memory stick or an SD card) may be applied. These recording media may be used as a single unit as in the first embodiment, and each member to be replaced at the time of setup change (for example, any one of the chuck portion 48, the stationary die 34, the movable die 35, etc.). You may prepare.

(C3) In Embodiments 1 and 2, barcodes 21c and 48a (that is, one-dimensional codes) are applied as code information, but two-dimensional codes such as QR code, PDF417, and data matrix (Data Matrix) are applied. May be. In the case of a two-dimensional code, since the amount of information that can be recorded increases, for example, the structure itself of the data file F shown in FIG. 5 or a part thereof can be recorded. Therefore, the storage amount of the storage unit M can be reduced. In addition, OCR characters (for example, characters standardized by JIS-X9001, X9003, X9005, X9006, X9008, X9009, etc.), symbols, etc. may be applied.

(C4) In Embodiment 2, the barcode 48a is read using the imaging device 22b. However, other code information may be read. The code acquisition means 23 is configured so that characters can be recognized, and one or both of the changeover number 21a and the changeover name 21b shown in FIG. 4 are recorded in the chuck portion 48 together with the barcode 48a. If it carries out like this, the code | symbol acquisition means 23 can acquire a code | symbol, after recognizing the character recorded as the setup change number 21a or the setup change name 21b. In particular, as shown in FIG. 7, even if a part of the barcode 21c is damaged and cannot be read, it is possible to recognize the setup change number 21a and obtain the code instead. Therefore, the data file F can be set more reliably.

(C5) In Embodiments 1 and 2, the chuck portion 48 is provided in the drive device 46 via the support shaft 47 (see FIGS. 1 and 9), but the drive device 46 is provided in another manner. It is good. For example, a rotating shaft is used in place of the support shaft 47, and the connecting portion between the chuck portion 48 and the support shaft 47 is configured by a vertical or horizontal swing mechanism. In this way, the degree of freedom increases in the movement of the chuck portion 48, and the imaging device 22b can also take an image from the front of the chuck portion 48 regardless of the installation position. Accordingly, the code information such as the captured barcode 48a can be reduced in distortion, so that the recognition accuracy by the code acquisition means 23 is improved.

(C6) In the second embodiment, the imaging device 22b is installed at a predetermined position (see FIG. 9), but the chuck portion 48 may be installed at a position where it can follow (for example, the driving device 46). This eliminates the need for grasping the position of the chuck portion 48, so that the detectors 42a, 44a and 46a are not required. Therefore, the cost can be reduced and the steps S30 and S31 in the setup change process shown in FIG. 10 can be eliminated.

(C7) In the first embodiment, the code reader 22a is always operated to read the barcode 21c (see steps S11 and S12 in FIG. 3), but the operator presses a read-only button. The bar code 21c may be read by operating the code reader 22a on condition that a predetermined operation is performed as described above (see step S10 in FIG. 3 represented by a two-dot chain line). According to this configuration, it is not necessary to determine whether or not the barcode 21c can be read (step S12 in FIG. 3), and it is possible to prevent malfunction due to the constant operation of the code reader 22a.

(C8) In the first and second embodiments, when searching the storage unit M for the data file F with the code that matches the acquired code, the setup change number Fa in the data file F is referred to (see FIG. 3 and step S14 of FIG. 11). If the code (that is, the setup change number Fa) is used as the file name of the data file F instead of this form, the search becomes easy and quick. Further, if all the data files F prepared corresponding to each setup change are made into a database, not only the search becomes easy and quick, but also the data management becomes easy.

(C9) In the first and second embodiments, the setup change mechanism 10 includes the robot device 12 for performing the setup change, and the molded product removal mechanism 40 provides the drive devices 42, 44, and 46 for taking out the molded product P. And rails 41, 43, 45 and the like (see FIGS. 1 and 9). Instead of this form, the setup change mechanism 10 may be provided with drive devices 42, 44, 46, rails 41, 43, 45, and the like, and the molded product removal mechanism 40 may be provided with the robot device 12. Further, both the setup change mechanism 10 and the molded product take-out mechanism 40 may include the robot device 12. Alternatively, both the setup change mechanism 10 and the molded product take-out mechanism 40 may include driving devices 42, 44, 46, rails 41, 43, 45, and the like.
In the first and second embodiments, the injection molding mechanism 30 is provided to produce (mold) the molded product P. However, other molding machines capable of producing the molded product P such as extrusion molding may be provided. Good.
Further, in Embodiments 1 and 2, a conveyor device is applied as the transport device 50, but a pallet or the like transported by a transport vehicle (for example, a forklift) may be applied.
