Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production simulation for cutting and crimping an electric wire having a desired circuit pattern using a cutting and crimping machine and a technique related thereto.

[0002]

2. Description of the Related Art Generally, an electric wire is intermittently fed and cut, and a terminal portion cut off by this cutting is subjected to terminal treatment such as peeling or crimp connection of terminal fittings in order to obtain a desired wire. A cutting and crimping machine is known which is adapted to sequentially manufacture processed products.
In this cutting and crimping machine, the terminal metal fittings to be crimped on both ends and the applicator (mold) for cutting and crimping are different depending on the circuit pattern of the electric wire, so the terminal metal fittings and applicator are replaced every time the circuit pattern is changed. While doing the cutting and crimping work.

Conventionally, a standard man-hour, that is, an average production time required for each electric wire has been used as an index for measuring the production progress of the cutting and crimping machine.

Conventionally, for example, a target number 10 based on standard man-hours is set on a performance display panel 101 as shown in FIG.
2, fill in the actual number 103, and the difference 104 between these,
This was placed near the cutting and crimping machine in an easy-to-see position to manage the progress of production of electric wires. This is to count up one by one for each predetermined number of seconds, and set the goal of the overall volume of these totals.

[0005]

However, the above-mentioned standard man-hour is an average production time required for one electric wire and mainly depends on the cutting length and size of the electric wire. It is not possible to accurately grasp the production volume due to the difference in the parts replacement time at a certain moment of the crimping machine and the applicator replacement time.

[0006] Therefore, by simply predicting the output based on the standard man-hours, for example, in the mass production in a large lot, the output of the electric wire is greatly calculated, while at the same time, exchanging parts or applicators, such as high-mix low-volume production. When the frequency is high, the amount of electric wire produced by the cutting and crimping machine is calculated to be low, and it is difficult to manage the progress in consideration of various production conditions such as lot size.

The above-mentioned volume display panel 101 (FIG. 14)
Counts up one by one every predetermined number of seconds, and has only set the goal of the total volume by totaling these, so the progress of individual tasks such as parts replacement is paced. It wasn't possible.

Due to such circumstances, the production work of the electric wire using the cutting and crimping machine depends largely on the specifications of each cutting and crimping machine and the skill and skill of the operator. Was not reflected.

Moreover, since there is no such thing as pulling the work pace of the operator like the assembly conveyor, it has been desired to properly grasp the target of the output.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cutting and crimping production simulation apparatus and a technique related thereto, which can contribute to the pacemaking of work while grasping an appropriate progress situation including parts replacement and the like. It is in.

Then, in step S5, the calculation result in step S3 or step S4 is displayed on the display device C3. The details will be described below.

<Mechanical tact setting process (step S1)
> Mechanical tact is the processing of one wire of each circuit pattern by the cutting and crimping machine in the state where all the external setup and the internal setup (collectively referred to as “manual switching work time”) are completed. In this case, first, in step S1, when a rubber plug as a seal is crimped together with a terminal fitting in step S1, as shown in FIG. Designation is performed on the model-specific tact setting screen 1. Here, "non-waterproofing machine" 2 that does not crimp rubber plugs on both ends of the wire, "one-end waterproofing machine" 3 that crimps rubber plugs on only one end of the wire, and "crimping rubber plugs on both ends of the wire" There is a distinction between the both-end waterproofing device 4 and any one of them is clicked by using a pointing input device (not shown) such as a mouse of the input device C1 and called a radio button. And specify. In FIG. 3, reference numeral 5 is an input field for inputting a model name, reference numeral 6 is an external output instruction button for instructing to output the machine tact setting result to an external device, and reference numeral 7 is the previous processing. Each shows a return button to return to.

4 to 6 are views showing the tact setting screen 1 for each model in which the tact time corresponding to the cut length of the electric wire is displayed.

Here, the tact time 13 in the case of non-waterproof is displayed when a one-end waterproof machine that can crimp a rubber plug to one end of an electric wire is used as a cutting and crimping machine without using any rubber plug. Is taken into consideration.

Further, FIG. 6 shows a model-specific tact setting screen 1 in the case where “both-end waterproofing machine” 4 is designated on the setting screen of FIG. 3, and the electric wire corresponding to the value of the cutting length 11 of each electric wire.

17 and 17 are displayed side by side. Here, "waterproof both ends"
Not only 17 but also "non-waterproof" 13, "A-end waterproof" 15 and "B-end waterproof" 16 columns are provided, as in the case of the "single-end waterproofer" 3 described above. As a result, it is considered to use a double-end waterproof machine capable of crimping rubber plugs on both ends of the electric wire for the purpose of not crimping any rubber stopper or for crimping the rubber stopper only on one side.

The tact times 12 to 17 shown in FIGS. 4 to 6 do not take into consideration the work time required for parts replacement and the like.

<Step of Setting Machine Switching Operation Time (Step S1)> Next, the setting input of the machine switching operation time in Step S1 is executed using the input device C1. The machine switching operation time is the time required for the switching operation of the cutting / crimping machine at the time of switching the lot of the electric wire circuit pattern, and does not include the manual work such as the outer setup and the inner setup.

FIG. 7 shows a machine switching operation time setting screen 20 for inputting different switching operation times depending on the type (machine) of the cutting and crimping machine. Here, the switching operation time of each cutting and pressing machine is set. That is, for each of the “side multi-head application supply device” 21, the “end application supply device” 22 and the “wire selector” 23,
The operation time for the switching work is entered in the “operation time” field 24.

The "side multi-head application supply device" 21 means a device for automatically exchanging a side type applicator (mold) corresponding to the case where the terminal fittings are supplied in a state where they are connected in a lateral direction. ing. Reference numerals 31a and 31b are input fields for inputting the number of applicators prepared in advance in the side multi-head application supply device, and the upper input field 31a.
The number of applicators prepared for one end (A end) of the electric wire and the number of applicators prepared for the other end (B end) of the electric wire are input to the lower input field 31b. Then, the input field 2 of the "operating time" 24 corresponding to this input field
The takt time required for exchanging one side-type applicator is input to each of 4a and 24b.

The "end application supply device" 22 means a device for automatically exchanging the end type applicator (mold) corresponding to the case where the terminal fittings are supplied in a state where they are vertically arranged. There is. Reference numerals 32a and 32b are input fields in which the number of applicators prepared in advance in this end application supply device is input, and the applicator prepared for one end (A end) of the electric wire in the upper input field 32a. The number of
The number of applicators prepared for the other end (B end) of the electric wire is input to the lower input field 31b. Then, the tact time required for exchanging one end-type applicator is input to the input fields 24c and 24d of the "operating time" 24 corresponding to the input fields 32a and 32b, respectively.

The "wire selector" 23 means a device for automatically changing electric wires. Reference numeral 33 is an input field for inputting the number of different types of wires prepared in advance in this wire selector, and the input field 24e of the "operating time" 24 corresponding to this input field indicates the number of wires per wire. The tact time required for replacement is entered.

<Manual Switching Operation Time Setting Step (Step S1)> Next, the switching operation time setting input in step S1 is executed using the input device C1. Here, the tact time when manually replacing the electric wire, the terminal metal fitting, and the applicator with respect to the above-mentioned “side multi-head application supply device”, “end application supply device” and “wire selector” is shown in FIG. It inputs into each input column in the switching operation time setting screen 40.

Reference numeral 41 is a time required for exchanging electric wire types, and reference numeral 42 is a time required for exchanging electric wires of the same type but different sizes (electric wire lengths).
Reference numerals 43 and 44 are times during which external setup is possible in the time required for replacing the electric wire or its size, and reference numerals 45 and 46 are side type (S) and end type (for terminal fittings and applicators, respectively). E) and none (invalid)
Time required to switch between the case of (J) and 4
Reference numeral 7 indicates the time during which the external setup is possible. In the columns of the terminal fitting and the applicator, (A) and (B) mean the one-side terminal (A terminal) and the other-side terminal (B terminal), respectively. Also, other items include special wire changing work 48 and time 49 required for rubber plug replacement, but description thereof will be omitted.

<Other Setting Steps (Step S1)> On the setting screen 50 shown in FIG.
Input items 51, "outer setup work loss (waiting time)" 52, and "complete outer setup range" 53.

The "number of operators" 51 means the number of persons involved in the cutting and crimping machine per machine. For example, 3
When operating four cutting and crimping machines by person, 0.75 (= 3
/ 4) 1.5 people (= 3 /) when 3 people operate 2 units
2) Entered as person.

The "outer setup work loss" 52 may stop the hand for some purpose during the outer setup, for example. Therefore, as a rule of thumb, how much hand waiting time (work loss) occurs during the outer setup. input.

In the "complete outer setup range" 53, the number of types of circuit patterns which can be set up in advance is input. For example, in the case of the above-mentioned “side multi-head application supply device” (see reference numeral 21 in FIG. 7), since the number of applicators that can be prepared in advance is plural, applicators that can be prepared in this side multi-head application supply device. Therefore, the number of types of circuit patterns that can be externally set up at one time is input in consideration of these matters. In addition, "F" in FIG.
Is indicated as 1 for each circuit pattern in advance.
It means a management instruction sheet that is printed on a sheet and carried to the manufacturing site.At the manufacturing site, when the F number is preselected and the external setup is performed, the preparatory number of the F is set to the “complete external setup range. It is shown that it is sufficient to input in the field of "53".

<Process selection step (step S2)> Returning to FIG. 2, in step S2, it is selected whether the operation time is calculated for the normal process or the complete external setup process. Here, when the number "1" is entered for the item "Complete outer setup range" 53 in the setting screen 50 shown in FIG. 9, "normal processing" is selected,
The process proceeds to the work time calculation process of the complete outer setup process in step S4. Further, when the number "2" or more is input in the item of "complete outer setup range" 53 in the setting screen 50 shown in FIG. 9, "complete outer setup processing" is selected, and the normal step S3 is performed. Proceed to the calculation processing of the processing work time.

<Calculation Process of Working Time of Normal Processing (Step S3)> FIG. 10 is a chart showing the concept of calculating the working time of normal processing. In step S3 in FIG. 2, as shown in FIG. 10, the cutting and pressing machine is operated K1 to K for each lot.
3 and operator's external setup S1 to S3 and internal setup U1
Work hours are calculated by arranging U3 in time series.

The operating time required for the operation K1 to K3 of the cutting and crimping machine is the tact time 12 to 17 entered on the tact setting screen 1 for each machine shown in FIGS. The value is selected according to the cutting length and the mode of waterproofing, and the values of the tact times 12 to 17 are integrated with the value of the number of lots to be manufactured.

Next, for each circuit pattern lot,
Out of the data input on the switching operation time setting screen 40 in FIG. 8, the wire 43, the size, the time for exchanging the terminal fittings and the applicator, and the time 43, 44, 47 at which external setup is possible are accumulated, and as shown in FIG. To the operation K1 to K3 of the cutting and crimping machine previously obtained so as to be parallel and proceed,
This is incorporated as a step of the external setup S1 to S3.

Regarding the lot of each circuit pattern,
Out of the data input on the switching operation time setting screen 40 of FIG. 8, the time 43, 44, 47 at which external setup is possible is subtracted from the wire, its size, the replacement time 41, 42, 45, 46 of the terminal fitting and the applicator. As shown in FIG. 10, when the respective operations K1 to K3 of the cutting and crimping machine obtained previously are completed and the external setups S1 to S3 A schedule is created so that the process continues from the later one of S3 ends and the later one (FIG. 10).

However, regarding the time required for the external setups S1 to S3 and the internal setups U1 to U3 incorporated in the schedule, considering that the work can be shared by a large number of operators, efficient work can be performed. When the value of the "number of operators" input on the setting screen 50 of 9 is N, the time obtained by dividing N from the time required for the outer setups S1 to S3 and the inner setups U1 to U3 is applied.

Furthermore, "outside setup work loss" 5 in FIG.
Let the percentage value entered in item 2 be r, and (1+
The value of r / 100) is calculated, and the value is set as the external setup S1 to S
The schedules shown in FIG. 10 are created by accumulating the required times of No. 3 and No. 3, respectively.

Here, when the time length of the operation K1 shown in FIG. 10 is longer than the time required for the external setup S1,
Further, when it is necessary to perform the mechanical switching operation R1 of the cutting / bonding machine, the switching operation times 24a to 24e input on the machine switching operation time setting screen 20 of FIG. 7 are read out, and these are cumulatively added to the switching operation R1. As a result, a schedule is created by applying it to the process of operation K1 so as to proceed continuously.

In this way, as shown in FIG.
It is possible to obtain a schedule showing the progress of work that reflects the outer setups S1 to S3 and the inner setups U1 to U3.

<Working Time Calculation Process of Complete Outer Setup Process (Step S4)> FIG. 11 is a chart showing the concept of calculating the working time of the complete outer setup process. In step S4 in FIG. 2, as shown in FIG. 11, the external setup work indicated by reference numerals S1 to S5 can be executed while the machine is in operation, and reference numerals U1 to U
The inner setup work of No. 5 is executed while the machine is stopped. As a concrete work example of the outer setup S1 to S5, for example,
In "Side multi-head application supply device", "End application supply device", "Wire selector", etc., the applicator without stopping each operation K1 to K5 of the cutting and crimping machine,
There is a replacement work when the terminal fittings and wires can be replaced. In addition, as specific work examples of the internal setups U1 to U5, for example, in the “side multi-head application supply device”, the “end application supply device”, the “wire selector”, etc., the respective operations K1 to K5 of the cutting and crimping machine are stopped. If you do not do so, or if you perform replacement work at the same time during automatic cutting and crimping, it becomes dangerous. is there. Each of these operations is an external setup S1 to S5
Since it depends on the configuration specifications of each cutting and crimping machine, it is judged and determined for each cutting and crimping machine.

Here, the number of lots of the external setups S1 to S5 to be continuously assembled up to now is the setting screen 50 shown in FIG.
The value input in the item of "Complete outer setup range" 53 in the above is applied. That is, “complete outer setup range” in FIG.
If the value "5" is entered in the item 53,
As shown in 1, the external setup S for five circuit patterns
1 to S5 are sequentially connected to each other, and the schedule is created by incorporating the circuit operations of the lots of the five circuit patterns so as to be superposed in parallel with each other.

At this time, as shown in FIG. 11, when it is necessary to perform mechanical switching operations R1 and R3 of the cutting and pressing machine, FIG.
The switching operation times 24a to 24e input on the machine switching operation time setting screen 20 are read out, and the accumulated operation times are set as the switching operations R1 and R3 so that the steps of the respective operations K1 and K3 are continuously applied. To create a schedule.

Regarding the lot of each circuit pattern,
Out of the data input on the switching operation time setting screen 40 of FIG. 8, the time 43, 44, 47 at which external setup is possible is subtracted from the wire, its size, the replacement time 41, 42, 45, 46 of the terminal fitting and the applicator. As shown in FIG. 11, the accumulated times are set as the steps of the inner setups U1 to U5, and all the previously set operations K1 to K5 of the cutting and crimping machine and the outer setups S1 to S5 are finished. Create a schedule so that it will continue from the later of the time you did it and the time later.

However, the outer setup S1 to S5 and the inner setup U
Regarding the time required for 1 to U5, if the number of operators is large, it is possible to perform the work efficiently by sharing the work, and the value of the “number of operators” input on the setting screen 50 of FIG. In case of, the external setup S1 to S5
And a schedule is created by applying a time obtained by dividing N from the time required for the internal setups U1 to U5.

Furthermore, "outside setup work loss" 5 in FIG.
Let the percentage value entered in item 2 be r, and (1+
The value of r / 100) is calculated, and this is set up as external setup S1-S
5 is added to each required time to create a schedule as shown in FIG.

In this way, if the external setups S1 to S5 of lots of a plurality of circuit patterns are collectively executed, for example, as shown in FIG. 10, the external setup (1) is performed for the time of operation (1) K1. It is possible to cancel out the hand waiting time caused by the short time of S1 and the time loss caused by the long time of the external setup (2) S2 with respect to the time of the operation (2) K2, which is wasteful. It is possible to efficiently execute the external setups S1 to S5 by reducing the waiting time as much as possible.

<Display Step on Display Device (Step S5)> As described above, the simulation result (schedule) at step S3 or S4 is displayed on the display device C3 to notify the operator on site of the actual work. Give feedback on the progress.

Specifically, the time is measured in the computer main body C2, and the next external setup S1-
As the work of S5 and the internal setup U1 to U5, which part needs to be replaced (etc.) and the remaining time until the replacement work time of the part is displayed on the setup display screen 61 of FIG. 12, for example. Display in real time. Reference numerals 62 to 63 in FIG. 12 are display fields in which the names of respective parts of the terminal fitting, the applicator and the rubber plug to be replaced are displayed, and the reference numeral 65 is the remaining time until the replacement of these parts in real time. Reference numeral 66 indicates a display column displayed, and reference numeral 67 indicates a display column displaying the line type of the electric wire to be replaced, and reference numeral 67 indicates a display field displaying the remaining time until the electric wire is replaced in real time.

The types of the parts 62 to 63, 66 displayed on the setup display screen 61 include, for example, a replacement completion button 68 arranged on the right side of each of the parts and a pointing input device (such as a mouse of the input device C1). It is not changed unless a predetermined operation such as clicking (not shown) or pressing a predetermined key (function key) on the keyboard is performed. This is because the case where the actual work deviates from the simulation result (schedule) is taken into consideration.

If the parts are not replaced even if the actual time has passed the scheduled parts replacement time, the remaining time 6
The signs of 5, 67 are displayed with a minus sign, for example. As a result, the operator can
It can be easily recognized that the delay is longer than the simulation result (schedule).

Then, when the operator replaces the part by the actual work, the progress status of the actual work is displayed for the part by a predetermined operation on the input device C1 such as clicking the replacement completion button 68 with a mouse or the like. Transmit to C2. At this time, since the operated part does not need to be displayed on the setup display screen 61, the following parts 62 to 63, 66 are moved up and displayed again.

Further, the time measured in the computer main body C2 is compared with the progress obtained by the simulation result (schedule), and the actual progress is compared with the ideal progress obtained by the simulation result (schedule). Whether it is advanced to some extent is displayed as a percentage as shown in FIG. Thereby, the evaluation of the operator's progress with respect to the simulation result (schedule) can be objectively displayed.

As described above, the contents of the previous switching work and the remaining time can be notified in real time by using the simulation result (schedule) considering the outer setups S1 to S5 and the inner setups U1 to U5. It is possible to give detailed instructions as well as perform accurate pacemaking, and improve work efficiency. Further, since the strict progress management can be performed using the objective simulation result, it is possible to reduce the influence of the skill and skill of the operator.

[0060]

According to the first and sixth aspects of the present invention, the mechanical tact of the cutting and crimping machine, the manual work switching work time and the switching work time that occur when the cutting and crimping machine is switched. Of the switching work time is input in parallel with the operating time of the cutting / crimping machine calculated based on the machine tact by inputting the external setup possible time of the The schedule is created by incorporating the time during which the external setup is not possible in the switching work time after the end of the time during which the external setup is possible and so as not to overlap the operating time of the cutting and crimping machine. , The schedule created here is displayed on the display unit to notify the operator of the site, and the progress status of the actual work for the schedule is displayed on the display unit. Since strict progress management can be carried out with an objective schedule, it is possible to reduce the influence of the operator's skill level and skill, and to perform accurate pacemaking and improve work efficiency. can do.

According to the second and sixth aspects of the present invention, when the cutting and crimping machine switching work is carried out by a plurality of operators, the number of operators per cutting and crimping machine is large. Enter the time, and the time during which the external setup is possible and the time during which the external setup is not possible in the switching work time.
Since the schedule is created by dividing by the number of people, an appropriate schedule can be created.

According to the inventions of claims 3 and 6, the degree of hand waiting time that occurs in the external setup is input,
Since the schedule can be created by correcting the external setup time of the switching work time according to the degree of hand waiting time, a realistic and reasonable schedule can be created.

According to the inventions of claims 4 and 6, the number of lots that can be pre-prepared and externally set up is input in advance, and the external setup of the lot number is continuously performed in parallel with the operating time of the cutting / bonding machine. Incorporation so that it will progress in succession, and of the switching work time, the time when external setup is not possible,
The schedule is created by continuously incorporating lots of lots at a timing after the end of the time when the outer setup is possible and at a timing that does not overlap the operating time of the cutting and crimping machine, so the outer setup of lots with multiple circuit patterns can be summarized. By doing so, the waiting time caused by the short external setup time with respect to the operating time of the cutting and crimping machine, and the time loss due to the long external setup time with respect to the operating time,
It becomes possible to offset each other, and it is possible to reduce wasteful waiting time as much as possible and execute efficient external setup.

According to the fifth and sixth aspects of the present invention, the machine switching operation time associated with the lot switching of the cutting and crimping machine is input, and the machine switching operation time is added to the operating time of the cutting and crimping machine. Since the schedule is created in parallel with the time when the external setup is possible, the schedule can be created by properly considering the machine switching operation time.
