Description

[Detailed explanation of the idea]

In the present invention, for example, the sheet is unwound from a long sheet roll while being measured and wound onto a cassette-type winding shaft, and the amount of winding is adjusted to a preset desired length. When the detected value of the actual operating amount corresponds to the set value, the predetermined value is The present invention relates to a device for displaying set values during manual setting, set values after setting is completed, and detected values associated with operation in a batch-type operating machine configured to automatically stop operation. This type of batch-type operating machine stops the set values at various times, so in order to improve work accuracy and efficiency, it is important to check whether the set values during manual setting match the actually set values. There is a strong need to check each time, and while a predetermined operation is in progress, there is also a need to judge how far the predetermined operation has progressed, or how far it will end. In other words, while the machine is not operating, it is necessary to display the set value during manual setting, and while the machine is running, it is necessary to display the set value and detected value after the setting is completed. Therefore, conventionally, a display section for displaying set values during manual setting and after completion of setting, and a display section for displaying detected values are separately provided, and these display sections can be used both during operation and when the operation is stopped. Both displays were kept active. By the way, it is absolutely necessary to display the set value during manual setting while the operation is stopped, and while it is highly necessary to display the detected value during operation, it is necessary to display the set value after the setting is completed. It is not necessarily necessary for the entire time, but it is sufficient if it can be displayed as needed. However, conventional methods display various information by providing two display sections that are always activated, which not only wastes display energy but also has the disadvantage that the display section occupies a considerable area of the control panel. Not only that, but the display section and its driving circuit are relatively expensive, and providing two display sections has the disadvantage that the entire structure becomes expensive, so there is room for improvement. The present invention has been developed in view of the above-mentioned circumstances, and its purpose is to enable various types of information to be appropriately displayed while using one display section. The characteristic configuration of the display device in the batch-type operating machine according to the present invention includes a setting value storage unit comprising a setting storage means for storing setting values during manual setting and a setting value storage means for storing setting values after the setting is completed. In addition, an output unit for the detected value is provided, and information from the setting storage means is displayed while the operation is stopped based on information from the operation state detection means for detecting whether or not the operation is in progress. A common display section is provided to display information from the output section during operation, and a switching section is provided for display content switching operation to switch to a state where information from the set value storage means is displayed during operation. and its action,
The effects are as follows. That is, one common display section can display manually set values when the vehicle is stopped, and display detected values when the vehicle is running, without requiring any special operations. Furthermore, during operation, the set value after setting can be displayed on the shared display section by operating the switching section. Therefore, by selectively displaying various types of information using one common display section, it is possible to save display energy and reduce the cost of the overall structure, and moreover, it is possible to save display energy and reduce the cost of the overall structure. By making it possible to display the two major displays, that is, the display of the set value during manual setting when the operation is stopped, and the display of the detected value during operation, without performing any special operations, Even though various information is displayed using one common display section, it is possible to improve usability, and as a result, we have achieved a display device for batch-type operating machines that has great practical advantages. Tsutsuta. Hereinafter, embodiments of the present invention will be described based on the drawings. In the circuit configuration shown in FIG. 1, which shows an example of a display device, 2 is an in-operation check circuit for detecting whether or not the batch-type operating machine 1 is in operation, and 3 is a circuit for switching display contents using a manual switch. switching section,
4 is a setting value storage unit, and a setting register 4A serves as a setting storage means for storing setting values during manual setting.
A two-stage register of the setting value register 4B is used as a setting storage means for storing the setting value after the setting is completed. 5' is the output part of the detected value of the actual operating amount,
A detected value register 5' is used. 6 is a detector. 7 is a display register, each register 4A, 4
B, 5' via normally open contacts r ₁ , r ₂ , r ₃ . 9 is a common display section for setting values and detected values;
is a display drive circuit. R ₁ , R ₂ , and R ₃ are relays for the normally closed contacts r ₁ , r ₂ , and r ₃ and are provided in the register selection signal circuit 10 . Of this circuit 10, 11
is an AND element, 12 is a NOT element, and 13 is an OR element. The functions of this display device are shown in the table below.

[Table] In other words, if a set value is set before starting operation (while stopped) with switching section 3 off, that value will be entered in setting register 4A, and on the other hand, relay _R1 will operate and contact _R1 will close. The contents of the setting register 4A are transferred to the display register 7, and the setting value is displayed on the display section 9. When switching unit 3 is turned on before starting operation (while stopped), relay R ₃ is activated and contact R ₃ is closed, so that the value detected in the previous work cycle is stored in the detected value register 5'.
The final detected value stored in is transferred to the display register 7 and displayed on the display section 9. When the operation starts, the check circuit 2 outputs an output, and the contents of the setting register 4A are transferred to the setting value register 4B. Further, the actual work amount of this work cycle is inputted to the detected value register 5' via the detector 6. This value changes sequentially (increasing or decreasing)
do. When switching section 3 is in the OFF state, relay R ₃
operates and the contact _r3 closes, so the contents of the detected value register 5' are transferred to the display register 7 and displayed on the display section 9. If you want to check the set value of this cycle while driving, switch section 3 is turned on. Relay R ₂
is activated and the contact _r2 closes, so the contents of the set value register 4B are transferred to the display register 7 and displayed on the display section 9. The circuit configuration shown in FIG. 1 is one preferred embodiment, and the present invention is of course not limited to this, and generally any circuit having the functions shown in the flowchart of FIG. Bye. Further, a failure detection circuit (not shown) may detect that a failure has occurred in the machine or the control circuit during operation, and the display unit 9 may be triggered by this detection signal, thereby providing a failure display function. . Note that the detected value register 5 may be omitted and the contact _r3 may be directly connected to the detector 6. Next, an example of the batch type operating machine 1 will be explained using a sheet measuring and winding machine shown in FIG. Reference numeral 22 denotes a mounting portion for the original fabric roll 21 on which the long sheet 20 is wound, and 23 represents a winding shaft for winding up the sheet 20, which is constructed in the form of a cassette that can be attached to and detached from the holder 24. 25 is the mounting part 2
The pulse encoder 2 is pressed so that the sheet 20 is pressed against the rotary shaft 25 by the sheet feeding rotary shaft 25.

An automatic operation command push button 32, an emergency stop command button 33, an automatic operation possible display lamp 34, and the like are provided.
It is preferable that the switching unit 3 automatically returns to the OFF state when the pushing force is removed. The end of the sheet 20 is manually moved onto the winding shaft 28.
Wrap it around. Due to the air suction described above, the end portion of the sheet is suctioned and held on the winding shaft. When the operation command push button 31 is turned on, the operation of each part is driven, and the sheet 20 of the original fabric roll 21 is
It is wound up in 3. During this time, the measurement values obtained by the pulse encoder 26 up to that moment are displayed one by one on the digital display section 9. Further, when the push-button type switching section 3 is pressed, the setting value is displayed on the display section 9, and it is possible to reconfirm how many meters of winding the current cycle is for, if necessary. The drive unit 35 is controlled to decelerate when the control panel 36 detects winding up to a point slightly short of the set sheet length (for example, 1 m), and is stopped when the set sheet length is detected exactly. Next, the cylinder 37 is extended and the cutter 28
The sheet 20 is cut at. The cutter 28 returns to its home position after cutting. The cut end of the sheet 20 is manually attached to the winding shaft 23.
Wrap it around. Next, the holder 24 is sent out, and the sheet is wound up from the winding shaft 2 from the holder 24.
Take out 3. Return the holder 24 and proceed to the next cycle. When winding the same length as the previous time, setting the set value can be omitted. In this case, by pressing the push-button switching section 3, the previous final winding shaft will be displayed on the display section 9, so that it can be reconfirmed. When winding different lengths, the clear key is pressed in the setting section 30, and the set value is set while checking the numerical value appearing on the display section 9 using the numeric keys.
