[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanger system used for transporting parts of sewing products.

[0002]

[Prior art]

【Example】

 An embodiment of the present invention will be described below based on the embodiment shown in the drawings.

FIG. 1 is a schematic top view of an embodiment of the hanger unit of the present invention. In the figure, 2 is an outer rail, 4 is an inner rail, and a hanger unit (not shown) can grip the part and travel on these rails 2, 4 in the direction of the arrow. A plurality of sewing stations 6 are arranged below each of the rails 2 and 4. A scramble device 8 is provided corresponding to each sewing station 6. The scramble device 8 has a scramble rail that can move between the rails 2 and 4, and by placing the hanger unit on the scramble rail, the destination of the hanger unit on the rails 2 and 4 can be changed. The scramble rail is connected to either the outer rail 2 or the inner rail 4 when not operating.

During normal production, the outer rail 2 functions as a rail (main line) of the production line, and a hanger unit that cannot be processed at any sewing station 6 is conveyed to the inner rail 4 by the scramble device 8, After passing through the sewing station 6, it is returned to the outer rail 2 before the next sewing station 6. Therefore, in this case, the inner rail 4 functions as a sub line.

When it becomes necessary to produce an express item, the functions of the outer rail 2 and the inner rail 4 are reversed, the outer rail 2 functions as a subline, and the inner rail 4 functions as a mainline. At the same time, prevent the express goods from flowing to the outer rail 2.

FIG. 2 is a block diagram of an example of a control device for realizing such function switching, and a similar control device is provided for each sewing station 6. Each scrambler 8 is provided with an outer rail sensor 10 and an inner rail sensor 12. The outer rail sensor 10 is for detecting whether or not the scramble rail of the scramble device 8 is connected to the outer rail 2. The inner rail sensor 12 has the scramble rail connected to the inner rail 4. It is for detecting whether or not it is present.

An outer rail passage sensor 14 and an inner rail passage sensor 16 are provided on the outer rail 2 and the inner rail 4 downstream of the scramble device 8, respectively. The outer rail passage sensor 14 and the inner rail passage sensor 16 detect whether or not the hanger unit passes on the outer rail 2 or the inner rail 4 on the downstream side of the scramble device 8, and at the same time, the rails 2, 4 Is for detecting whether the hanger unit is full. In the present invention, it is used to detect whether the hanger unit is full.

Each sewing station 6 includes an outer rail station control circuit 24, a hand push switch 25 connected to the outer rail station control circuit 24, an inner rail station control circuit 26, and an express switching circuit 20. A limited express closing switch 22 connected to the limited express switching circuit 20 is provided. The outer rail station control circuit 24 and the inner rail station control circuit 26 are for performing known control for raising the hanger from the sewing position in each of the rails 2 and 4, respectively.

During normal production, as shown in the figure, the express closing switch 22 is OFF, and the outer rail sensor 10, the outer rail passage sensor 14, and the outer rail station control circuit 24 related to the outer rail 2 are scrambled respectively. The circuit 28 is connected to the main rail sensor input terminal 10A, the main rail passage sensor input terminal 14A, and the main station control circuit input / output terminal 24A.

On the other hand, the inner rail sensor 12, the inner rail passage sensor 16 and the inner rail station control circuit 26 related to the inner rail 4 respectively include a sub-rail sensor input terminal 12 A and a sub-rail passage sensor input terminal 16 of a scramble control circuit 28. A and the sub-rail station control circuit input / output terminal 26A. The scramble control circuit 28 further has a scramble solenoid operation signal output terminal 30A, and the scramble solenoid 30 is connected to the scramble solenoid operation signal output terminal 30A. The scramble solenoid 30 is for moving the scramble rail of the scramble device 8 between the outer rail 2 and the inner rail 4.

When the sewing stations 6 that perform the same sewing process are continuous, it is not necessary for the operator to transfer the sewn product that has been sewn in the previous sewing station 6 to the next sewing station 6, By pressing the hand push switch 25, the hanger unit is moved from the outer rail 2 to the inner rail 4 by the scramble device 8 and jumps over the next sewing station 6 and is further scrambled by the scramble device 8 at the next sewing station 6. Returned to 2. At this time, the outer rail sensor 10 and the inner rail sensor 12 detect the state of the scramble device 8 (whether the scramble rail is connected to the outer rail 2 or the inner rail 4), and the scramble control circuit 28 detects it. It is determined whether to activate the scramble solenoid 30.

When the limited express closing switch 22 is turned on, due to the action of the relay, the main rail sensor input terminal 10A, the main rail passage sensor input terminal 14A, the main station control circuit input / output terminal 24A, the inner rail sensor 12, the inner rail sensor 12, The rail passage sensor 16 and the inner rail station control circuit 26 are connected. On the other hand, the outer rail sensor 10 and the outer rail station control circuit 24 are connected to the sub-rail sensor input terminal 12A and the sub-rail station control circuit input / output terminal 26A, respectively. It should be noted that the sub-rail passage sensor input terminal 16A is grounded and receives a signal that is always ON. Further, the signal transmitted from the scramble control circuit 28 to the scramble solenoid 30 is inverted by the inverter.

At the sewing station 6 where the express item held by the hanger unit arrives when the express item is loaded, the express entry switch 22 is turned on to turn on the sub-rail of the scramble control circuit 28 as described above. The sensors and circuits of the inner rail 4 and the sensors and circuits of the outer rail 2 are interchangeably connected to the respective input terminals except the passage sensor input terminal 16A. Further, since a signal that is always ON is input to the sub-rail passage sensor input terminal 16A, the outer rail 2 is determined to be full, and the running of the hanger unit on the outer rail 2 is stopped by a publicly known method. Therefore, only the inner rail 4 can be operated, and the express goods can flow through the inner rail 4. Therefore, the operator who is in charge of the sewing station 6 can receive the sewn product conveyed by the inner rail 4 from the hanger unit and sew on the sewing station 6.

By sequentially performing the same switching at each sewing station 6, it is possible to finish the express goods while leaving the sewn goods in process on the outer rail 2, so that the express goods can be produced more quickly than before. Becomes

The hanger system of the present invention has been described above based on an embodiment, but the present invention is not limited to this embodiment, and switching between normal work and express work is performed based on a command of a soft computer or the like. You may do it. It is also possible to replace the limited express switching circuit 20 with a CPU or the like.
