Description

  The present invention relates to a control system in a processing facility with a changer for exchanging a tool holder such as a turret using a tool holder changer for a plate material processing machine such as a punch press or other processing machines.

Conventionally, a turret type is generally used as a punch press capable of replacing a plurality of tools. However, in the turret punch press, the types of punch tools that can be held in the turret are limited, and various processes cannot be performed.
In order to solve such problems, a multi-turret type tool holder has been proposed in which a turret type tool holder equipped with a plurality of punch tools is detachably held at a plurality of circumferential positions of a rotatable tool holder magazine. (For example, Patent Document 1). In this method, a desired tool holder is indexed to a predetermined processing position by turning the tool holder magazine, and the determined tool holder is turned to use the desired punch tool in the tool holder for punching. .

In this type of punch press, the tool holder on which a plurality of punch tools are mounted is replaceable with respect to the tool holder magazine. Therefore, a tool holder is prepared outside the tool holder magazine, and the tool holder is attached to the tool holder magazine. Many punch tools can be used by exchanging the tool holder.
Also, when using a punch tool mounted on the same tool holder that is indexed at the machining position, it is only necessary to rotate a tool holder that is smaller and lighter than the tool holder magazine, etc. Can be shortened and efficient punching can be performed.

The necessary tool holder confirmation command 51 is described at a position immediately before a command 50b that changes the identification number of the tool holder 7 in the tool indexing command 50b among the series of machining commands 50 of the machining program 36.

  In response to the necessary tool holder confirmation command 51, the necessary tool holder confirmation means 38 transmits the exchange inquiry information D1 including the tool holder identification number in the necessary tool holder confirmation command 51 to the changer control device 32, and the tool It is confirmed that the tool holder 7 corresponding to the holder identification number is in the punch press 1, and if there is, the process of proceeding to the next command is performed. Whether or not the tool holder 7 corresponding to the tool holder identification number is in the punch press 1 is confirmed by the stored information of the retained tool holder storage means 40.

  In response to the exchange inquiry information D1 output from the processing machine control device 31, the confirmation exchange means 45 provided in the changer control device 32 indicates that the tool holder 7 corresponding to the tool holder identification number is currently in the changer operation information 44. It is a means for confirming that it corresponds to the loading order, and for causing the tool holder changer 3 to perform the replacement operation of the tool holder 7 in the case where it corresponds. Note that the changer operation information 44 is marked with a flag or the like indicating that the line corresponds to the current loading order. When loading or unloading by the tool holder changer 3 is performed, the mark moves to the next line. By collating with this mark, it can be confirmed that it corresponds to the current loading order. The confirmation exchange means 45 is provided as one instruction in the changer control program 43, for example.

  In this embodiment, the confirmation and exchange means 45 confirms whether or not the tool holder 7 corresponding to the tool holder identification number is in a predetermined exchangeable state, in addition to being in the current loading order. The exchange operation is performed when possible. Further, the confirmation exchange means 45 returns a reply D2 indicating whether the exchange is possible or not to the processing machine control device 31. The definition of the predetermined exchangeable state is set as appropriate. For example, when the tool holder 7 to be loaded is brought to the vicinity of the replacement index position R of the in-machine tool holder magazine 5 by the tool holder changer 3, it is set to be replaceable.

  The necessary tool holder confirmation means 38 of the processing machine control device 31 proceeds to the next command after the exchange operation of the tool holder 7 of the tool holder changer 3 when the exchangeable reply D2 is exchangeable content. It is supposed to be If the exchange possible / impossible response D2 is a non-replaceable content, the next command is advanced without performing the exchange operation.

  Operations of the processing machine control device 31 and the changer control device 32 using the changer operation information 44 will be described together with specific examples. Now, as shown in FIG. 4, in the in-machine tool holder magazine 5 of the punch press 1, the tool holders 7 are held in all (eight) tool holder holding portions 5a, and each identification number is assigned.

It is assumed that the tool holder 7 having the identification numbers T03 and T05 is held in two of the eight tool holder holding portions 6a in the external tool holder magazine 6.

  The machining program 36 with the file name “001” has a content in which “T01”, “T03”, and “T05” are sequentially used as the tool holder 7 in the example of FIG. In this machining program 36, a necessary tool holder confirmation command 51 is described immediately before each machining command 50 in which the tool holder 7 to be used is changed, and the identification number of the tool holder 7 after the change is included in this confirmation command. is described. For example, the necessary tool holder confirmation command 51 immediately before the machining command 50 having “XY-T0101” is indicated as “M ○ Δ01” including the tool holder identification number “T01” in the machining command 50. Yes. Note that the initial letter “T” is omitted because it is not necessary for identification.

  In the example shown in the figure, the changer operation information 44 is such that the tool holder 7 of T09 is first unloaded and the tool holder 7 of T03 is loaded first, and then the tool holder 7 of T10 is unloaded and T05 The tool holder 7 is carried in.

Now, it is assumed that the machining program 36 with the file name “001” is executed and the first necessary tool holder confirmation command 51 (M ○ Δ01) is read by the calculation control unit 37. At this time, the necessary tool holder confirmation means 38 of the arithmetic control unit 37 transmits the exchange inquiry information D1 including the tool holder identification number (T01) in the necessary tool holder confirmation instruction 51 to the changer control device 32.
The confirmation exchange means 45 of the changer control device 32 confirms that the tool holder 7 corresponding to the tool holder identification number (T01) corresponds to the current loading order in the changer operation information 44 in response to the exchange inquiry information D1. If applicable, it is checked whether or not the tool holder 7 is in a replaceable state.
In this example, since the tool holder 7 with the identification number (T01) does not correspond to the current carry-in order, a non-replaceable response D2 is returned to the processing machine control device 31.

  When there is this reply D2, the necessary tool holder confirmation means 38 confirms that the tool holder 7 corresponding to the tool holder identification number (T01) is in the punch press 1 regardless of whether the exchange is possible or not. In the example of the figure, the tool holder 7 corresponding to the identification number (T01) is in the punch press 1. Therefore, the necessary tool holder confirmation unit 38 performs a process of proceeding to the next command. Whether or not the tool holder 7 corresponding to the tool holder identification number (T01) is in the punch press 1 is confirmed by the stored information of the retained tool holder storage means 40.

  Thus, after confirming that the necessary tool holder 7 is in the machine by the necessary tool holder confirmation instruction 51, the next machining instruction 50 (XY-T0101) using the tool holder 7 (T01) is executed. Is done.

When the machining program 36 is executed and comes immediately before the machining command 50 using another tool holder 7 (T03), the necessary tool holder confirmation command 51 (MＭΔ03) is read.
At this time, the necessary tool holder confirmation means 38 transmits the exchange inquiry information D1 including the tool holder identification number (T03) in the necessary tool holder confirmation instruction 51 to the changer control device 32.
The confirmation exchange means 45 of the changer control device 32 confirms that the tool holder 7 corresponding to the tool holder identification number (T03) corresponds to the current loading order in the changer operation information 44 in response to the exchange inquiry information D1. If applicable, it is checked whether or not the tool holder 7 is in a replaceable state.

In the example shown in the figure, since the tool holder 7 at T03 corresponds to the current loading order, it is subsequently confirmed whether or not the tool holder 7 is in a replaceable state. Whether or not it is in a replaceable state is determined by setting an appropriate standard. For example, when the tool holder 7 to be carried in is prepared by the tool holder changer 3 up to the vicinity of the replacement index position R of the in-machine tool holder magazine 5 as described above, a reference is determined to be in a replaceable state. Keep it.
By determining whether or not it is in the replaceable state, the tool holder 7 to be loaded is far from the replacement index position R of the in-machine tool holder magazine 5, and the operation by the tool holder changer 3 takes time. In such a case, a measure not to carry in can be taken.

Here, it is assumed that the state is exchangeable. In this case, the confirmation exchange means 45 causes the tool holder changer 3 to carry out the tool holder 7 of T09, carry in the tool holder 7 of T03, and return a replaceable reply D2 to the processing machine control device 31. .
The necessary tool holder confirmation means 38 of the processing machine control device 31 responds to the response D2 and waits for completion of the replacement by the tool holder changer 3, and the tool holder 7 corresponding to the tool holder identification number (T03) is punch-pressed. Confirm that it is within 1. In the example of the figure, the tool holder 7 corresponding to the identification number (T03) is not initially in the punch press 1, but the tool holder 7 corresponding to the identification number (T03) is replaced by the tool holder changer 3 described above. Since it exists in the punch press 1, it is determined that the corresponding tool holder 7 (T03) is in the punch press 1.

  Therefore, the necessary tool holder confirmation unit 38 performs a process of proceeding to the next command. Thus, after confirming that the necessary tool holder 7 is in the machine by the necessary tool holder confirmation instruction 51, the next machining instruction 50 (XY-T0301) using the tool holder 7 (T03) is executed. Is done.

  If it is not in the exchangeable state at the time of confirmation by the confirmation exchange means 45, the reply D2 sent from the confirmation exchange means 45 to the processing machine control device 31 is a non-replaceable content. In this case, the necessary tool holder confirmation means 38 of the processing machine control device 31 determines that the tool holder 7 (T03) is not in the machine when checking whether the tool holder 7 (T03) is in the machine. The program 36 waits without proceeding to the next instruction. In such a standby state, the necessary tool holder confirmation means 38 may be made to output the replacement inquiry information D1 again, or an alarm signal may be generated.

The changer control device 32 is operated by a changer control program 43 that is different from the processing program 41 of the processing machine control device 31. Since the changer operation information 44 is set, punching by executing the processing program 36 is performed. During the operation, the operation of the tool holder changer 3 can be advanced.
Therefore, in the above example, normally, the execution of the machining program 36 has progressed and the tool holder 7 of T03 is required, so that it can be exchanged at the time of confirmation by the confirmation exchange means 45. It should be noted that the machining program 36 in the figure is shown with a reduced number of instructions for the sake of simplicity of explanation, and the tool holder 7 needs to be replaced at the initial stage of machining. It is possible to perform a large amount of machining in the tool holder knitting state of the in-machine tool holder magazine 5 when the machining program 36 is started.

As described above, the changer-equipped machining facility control system has the changer operation information 44 in which the changer control device 32 sets the identification numbers of the tool holders 7 that are carried into and out of the punch press 1 from the tool holder changer 3 in the necessary order. Therefore, the tool holder changer 3 can be operated in advance according to the changer operation information 44 before the tool holder 7 of the external tool holder magazine 6 is actually required by the punch press 1. For example, it is possible to take measures such as moving the tool holder 7 necessary for the punch press 1 next to the replacement index position R of the punch press 1. Therefore, the replacement time of the tool holder 7 can be shortened.
In addition, since independent changer operation information 44 is set, for example, unlike the control method described in the conventional machining program including the control command of the tool holder changer, the execution order of the plurality of machining programs 36 can be freely set in the field. Even when the change is made, it can be dealt with by creating the changer operation information 44, and a complicated procedure for rewriting the changer control command in the machining program 36 is not required.

The creation of the changer operation information 44 and the addition of the necessary tool holder confirmation command 51 in the machining program 36 will be described with reference to FIG.
The automatic programming device 35 is means for creating a machining program 36A that is a base before adding the necessary tool holder confirmation command 51 to the machining program 36. The created machining program 36A is assigned a file name (displayed as “001” or the like in the figure). The automatic programming device 35 creates a machining program 36A according to setting criteria (not shown) by inputting dimension information of the plate material W as a material and graphic data indicating the shape of the plate material W after punching. To do.

The used tool holder information 55 is information that determines which identification number of the tool holder 7 is used in each machining program 36A. For example, the identification number (T10) of the tool holder 7 to be used for each file name of the machining program 36A. , T02,...)).
The original machining program 36A created by the automatic programming device 35 can be transmitted to the schedule creation device 34 via a network or a storage medium.

  The schedule creation device 34 can store a plurality of machining programs 36 </ b> A sent from the automatic programming device 35. The schedule creation device 34 has processing schedule creation means 57 for determining the order in which the machining programs 36A are executed and the number of machining by an operator input, and the execution order of the machining programs 36A thus determined is stored in the program storage means 56. The information on the number of processed pieces is stored together with the file name of the processing program 36A. The execution order information may be the order in which the machining programs 36A are arranged, or may be order information given to the file name of the machining program 36A or the address of its storage area.

  The used tool holder information 55 is stored in a predetermined storage area in the schedule creation device 34.

  The schedule creation device 34 includes changer operation information creation means 58, command addition means 59, and machining program transfer means 60.

The changer operation information creating means 58 is a means for creating the changer operation information 44 described above with reference to FIG. 4 by the transfer request F3 and sending it to the changer control device 32. The changer operation information 44 is generated by the changer operation information generating means 58 using the tool holder information 55 in accordance with the setting criteria.
The changer operation information creating means 58 creates the changer operation information 44 and sends it to the changer control device 32 every time a machining program is requested from the changer control device 32. As described above, the changer control device 32 controls tool change according to the sent changer operation information 44.

  The command addition means 59 is a command for confirming the necessary tool holder, which is a command for inquiring the changer operation information 44 and confirming the necessary tool holder 7 in the original machining program 36A created by the automatic programming device 35. It is a means to add. The command adding means 59 adds the necessary tool holder confirmation command 51 in accordance with the setting standard. For example, when the machining command 50 is a command using the tool holder 7 having an identification number (T01 or the like) different from that of the previous machining command 50 in the original machining program 36A, one line of the setting standard is set. It is assumed that the necessary tool holder confirmation command 51 is added before.

  The machining program transfer means 60 is a means for sending a machining program to the machine control device 31 in response to a transfer request F3 from the changer control device 32. The machining program 36 to which the necessary tool holder confirmation command 51 is added by the command addition means 59. Send.

When the power supply is started, the power supply is started from this higher order.
The loader control device 33 includes a manually operated start switch 61, data requesting means 63, and preparation completion notifying means 62. When the start switch 61 is operated, the data requesting means 63 sends data to the schedule creation device 34. Send a request signal F1. In response to the response signal F2, the preparation completion notification means 62 starts the changer control device 32 when the loader 4 enters a predetermined preparation completion state.

The changer control device 32 includes a start switch 64, a data request unit 66, and a preparation completion notification unit 65. The start switch 64 is activated by a preparation completion signal transmitted from the preparation completion notification unit 62 of the loader control device 33. Can be turned on. If the loader control device 33 is not provided, the start switch 64 of the changer control device 32 is for manual operation.
The data request means 66 of the changer control device 32 sends a data request signal F3 to the schedule creation device 34 at the start, and responds to the response signal F4. The preparation completion notification means 62 indicates that the tool holder changer 3 is in a predetermined ready state. Then, the processing machine control device 31 is started.
The start switch 67 of the processing machine control device 31 is turned on by a preparation completion signal transmitted from the preparation completion notification means 65 of the changer control device 32.

  The creation of the changer operation information 44 and the creation of the necessary tool holder confirmation command 51 in the machining program 36 from the start of the power supply of the control system will be specifically described. When starting up this processing equipment, the operator turns on the start switch 61 of the loader control device 33. By this ON operation, the data request unit 63 transmits a predetermined data request signal F1 to the schedule creation unit 34. The schedule creation means 34 responds to the data request signal F1, and uses the file name (for example, “001”) of the machining program 36 of the corresponding execution order stored in the program storage means 56 as the response signal F2 as the response signal F2. Send to 33. The contents of the machining program 36 may be sent together with the file name. In addition to this, the response signal F2 includes information on the material and dimensions of the plate material W as a material, a shelf number of the storage location, and the like. The information on the material, dimensions, and storage location is described as attribute information when the machining program 36A is created.

  The loader control device 33 responds to the response signal F <b> 2 and operates the loader 4 to carry the material plate material W into the punch press 1. When this loading is completed, the preparation completion notification means 62 turns on the start switch 64 of the changer control device 32.

In the changer control device 32, when the start switch 64 is turned on, the data request unit 66 sends a predetermined data request signal F3 to the schedule creation unit 34.
In response to the data request signal F3, the schedule creation unit 34 adds the necessary tool holder confirmation command 51 to the machining program 36A by the command addition unit 59, and creates the changer operation information 44 by the changer operation information creation unit 58. I do. The schedule creation means 34 sends the file name of the machining program 36 corresponding to the execution order and the created changer operation information 44 to the changer control device 32 as a response signal F4 to the data request signal F3.
In addition, in the schedule creation means 34, in response to the data request signal F3, the command addition means 59 adds the necessary tool holder confirmation command 51 to the original machining program 36A, and the added machining program 36 is controlled by the machine tool.
