Abstract

PURPOSE:To reduce time loss and prevent the generation of defective products by turning each handy switch off upon the termination of each work and providing a control panel with pilot lamps, actuated in succession interlockingly with the corresponding handy switches, for displaying the work plan of each planned part. CONSTITUTION:In case of changing work plans, the plan in operation and the following item are inputted into a control panel 2, and the necessary planned parts and planned work are then operated by a built in arithmetic unit, as well as only the parts requiring the planned work are turned on among the respective handy switches of all planned parts in a device 1 and the respective pilot lamps 3 of the control panel 2. A worker then performs the plan change of the part indicated by the handy switch at each planned part of the device 1 and turns each handy switch off one by one upon the termination of each work. Accompanied by this, the corresponding pilot lamps 3 of the control panel 2 are turned off in succession. The whole necessary plan changing work is terminated when all the handy switches and pilot lamps 3 are put off.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a work setup method for production equipment that requires complicated setup changes at many locations.

(Prior art) For example, in an insulator manufacturing factory, a wide variety of insulators are manufactured using the same equipment, but when changing the insulators manufactured from the current model number to the next model number, requires complicated setup changes at many parts of the equipment. Moreover, setup change work at each location requires a certain procedure for each location.Furthermore, depending on the current product number and the next product number, there may be parts that do not require setup change.

Therefore, in the past, only experienced workers could understand the necessary setup points and work procedures for each product number, and each worker needed to confirm the work with each other after the work was completed. Therefore, it took a lot of time to change setups. However, despite this, there are many problems such as forgetting or omitting setup work, which tends to lead to product defects.

(Problems to be Solved by the Invention) The present invention solves these conventional problems, allows anyone to understand setup change items for each product number, and improves work efficiency. This work was completed in order to provide a work setup method that can prevent product defects by preventing time loss due to verification, and also by eliminating forgetting or omission of setup work.

(Means for Solving the Problems) The present invention for solving the above-mentioned problems requires that, when changing the setup from the current product number to the next product number, the necessary work is calculated by the control panel at each setup point of the device. A hand switch is provided to display the procedure, and the light is turned off one by one at the end of each task, and an indicator light is provided on the control panel to centrally display the work procedure for each setup point. , each indicator light is activated in sequence in conjunction with each hand switch.

The present invention will be explained in more detail below with reference to embodiments shown in the drawings.

Figure 1 shows, for example, an insulator manufacturing equipment with 18 setup points (1) and a control panel for the setup (2).
Each location has a plurality of setup steps, and setup work must be performed in a fixed procedure. However, if, for example, the outer diameter of the insulator of the current part number and the insulator of the next part number are the same, there may be no need to perform setup work for a certain part. Therefore, in the present invention, by incorporating a calculation device into the control panel (2), it is possible to calculate and display the necessary setup locations and setup operations by manually inputting the current product number and the next product number.

Each setup point is equipped with a hand switch with an indicator light that displays the work procedure specific to each setup point, and the necessary work procedure calculated by the control panel (2) lights up these hand switches. This allows the display to be displayed for each setup location.

In addition, as shown in the figure, the panel of the control panel (2) is provided with an indicator light (3) that centrally displays the work procedure for each setup location. They are arranged in 18 rows corresponding to the setup locations, and in each row, a number of indicator lights (3) corresponding to the work procedure at each setup location are arranged in the - column. and device (1)
Each hand switch at each setup location and each indicator light (3) on the panel of the control panel (2) are in one-to-one correspondence.

When changing the setup, first input the current product number and the next product number into the control panel (2). Then the control panel (2)
calculates the necessary setup points and setup work using a built-in calculation device, and also calculates the setup points from each hand switch at each setup point of the device (1) and each indicator light (3) on the panel of the control panel (2). For example, only the parts that require work are turned on. Therefore, at each setup location of the device (1), the operator changes the setup of the part displayed using the hand switch, and at the same time turns off the light of the hand switch one by one at the end of each work. Along with this, the corresponding indicator lights (3) on the panels of the control panel (2) also turn off one after another. When all the hand switches and indicator lights (3) go out, all necessary setup changes have been completed.

(Effects of the Invention) As described above, according to the present invention, the necessary setup locations and setup operations can be automatically calculated and displayed on the control panel by simply inputting the current product number and the next product number. This eliminates the conventional disadvantage that only experienced people can know the necessary setup parts, and anyone can immediately know the necessary setup parts.

Further, according to the present invention, since the work procedure is displayed by the hand switch at each setup point of the device, even an inexperienced worker can follow the necessary work procedure and perform the work without making mistakes or mistakes.

What's more, the corresponding indicator lights on the control panel panel also light up, and at the same time as each hand switch is turned off one by one at the end of each work, the indicator lights on the control panel panel also turn off, so all indicator lights on the control panel panel are turned off. By disappearing, the completion of the setup can be easily confirmed, and there is no need for workers to confirm their work with each other as in the past. Therefore, even if production starts immediately, there is no risk of product defects due to omissions in setup or mistakes.

Although the above explanation has been made using an insulator manufacturing apparatus as an example, the present invention is not limited to this, and can be widely applied to general setup work that requires complicated setup work due to changes in product numbers. Yes, it goes without saying. As described above, the present invention has been able to solve the problems of conventional setup work at once, and has made an extremely large contribution to the development of industry.
