Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier device for carrying a carrier carrying an article such as a work cloth along a carrier rail.

[0002]

2. Description of the Related Art In a sewing factory or the like, various devices have been proposed for automatically carrying a carrier holding an article such as a sewn product to a work station arranged along a carrier rail.

For example, as shown in Japanese Patent Application No. 3-212462, some items such as a design code for distinguishing a product to be sewn by its design, a color code for distinguishing by color, etc. There has also been proposed a transfer device capable of presetting a transfer route or the like, which is the order of work stations corresponding to the order of the work processes, in accordance with the work processes performed on the sewn product or the like as a transfer plan.

In the case of this carrying device, at the time of loading, the carrying route of the workpiece to be sewn based on the carrying plan is associated with the number of the carrier holding the workpiece to be sewn. And
For each work station, read the carrier number attached to the carrier that is being transported, and follow the carrier route corresponding to that carrier number to sequentially transfer the carrier from the completed work station to the next work station. It is being transported.

In this method, when a transport plan is newly set, the operator considers the type of the workpiece to be sewn such as the above-mentioned design and color, and the function of each work station in order to appropriately construct the transport route. It is necessary to take into consideration the skills of the workers who work at the work station.

Therefore, it may be possible to store the previously used transport route and reuse it when a new transport plan is set. In this method, the transport route is searched from the set transport plan based on the design code. It is possible.

[0007]

In an actual conveying device, the sewing products to be sewn are usually put into the conveying device in consideration of the efficiency of the work such as sewing, so that the sewn products having the same design, color and size are continuously formed. And throw it in. Further, since the processed products having the same design, color, and size are generally manufactured in the same working process, they pass through the same conveying route.

Furthermore, the number of carriers that can be loaded at one time is limited due to the physical size of the loading station of the transport device. Since the number of lots of one design is generally several tens to several thousands, it is impossible to throw all lots by one loading operation, and multiple loading operations are required.

For the above reasons, it is more practical to set the transport plan as "set a design to 5 sets and set 20 sets" rather than setting "100 designs to be set". This is convenient in terms of the control of the transfer device as well as the input operation.

However, in order to create the transportation plan in this way, the same operation needs to be repeated 20 times, which requires a lot of time and effort for the creation work.

The present invention has been made to solve the above-mentioned problems, and when a transfer plan is newly created, the transfer plan is automatically created by the number of lots of the workpieces to be transferred. An object of the present invention is to provide a transfer device with a transfer plan table preparation device capable of creating data.

[0012]

In order to achieve this object, a carrying device with a carrying plan creating device of the present invention is a total production number input means for inputting the total number of products to be produced for which a carrying plan is to be established. And the number of inputting means for inputting the number of the objects to be transferred in one inputting operation, the total production number inputting means and the information input by the inputting quantity inputting means And a transportation plan setting means for automatically setting a plan.

[0013]

In the carrying device with the carrying plan preparing device of the present invention having the above-mentioned configuration, the total production quantity input means inputs the total production quantity of the conveyed objects for which the carrying plan is to be established.

The input number input means inputs the number of the objects to be conveyed to be inserted in one inserting operation.

Then, the transfer plan setting means automatically sets the transfer plan of the transfer device based on the information input by the total production number input means and the input number input means.

When an execution key (not shown) is pressed, a search process is executed based on the design code and the search result is displayed (S120). A search result display screen P4 in this embodiment is shown in FIG. From a large number of past data shown in FIG. 11, the design code “A
Only data that is "0101" are displayed.

In the present embodiment, as shown in the search result display screen P4 of FIG. 12, the design code is "A0101" and the route numbers are "1", "2", "5" and "7", respectively. Data is displayed as a search result. And
The optimum route is selected from the data narrowed down to four, and the route number "7" is set to the transport plan setting screen P2 in FIG.
You can enter it in the path number field at the bottom.

Next, in S50, the design code "A0101", the size code "11", which is to be put in, is to be input in the total production quantity input field at the bottom of the transfer plan setting screen P2 in FIG.
Enter the total number of products to be sewn with the color code "50" and the route number "7". Subsequently, in S60, the number of lines to be input in one input operation is input in the column of the number of input lines at the bottom of the transfer plan setting screen P2 in FIG. The number of loading units is limited depending on how many transfer bodies 36 can be loaded at one time from the loading station STa.

In S70, the host computer 100 sets S5.
The transport plan data necessary to transport the total number of transporters 36 input with 0 is newly generated. That is, based on the input total production number “40” and input number “5”, the number of times to be input (total production number ÷ one input number) is calculated, and the transportation plan data is created.

Next, in S80, the host computer 100 displays a table of transportation plans based on the transportation plan data generated in S70. That is, the design code “A0
FIG. 8 shows a transportation plan table set when "101", size "11", color code "60", route number "7", total production number "40", and input number "5" are input. This screen allows the operator to create and confirm a transport plan for the sewn workpiece.

The transfer plan can be easily set by the above procedure.

In addition, when the transport plan is created in the unit of the number that can be input at a time in this way, for example, the transport plan of each row in the table of the transport plan is color-coded as not input, during work, and completed. Displaying it is convenient because it can be used to manage the progress of work.

The embodiment of the present invention has been described above.
The present invention is not limited to these examples, and it goes without saying that the present invention can be implemented in various modes without departing from the spirit of the present invention.

For example, the maximum number that the loading station STa can carry out in one loading operation, which is stored in the host computer 100 that controls the transporting device instead of inputting the one loading number, is defined as one loading number. You can also do it. In this case, it is possible to further save the operator's labor for inputting by the operator.
