Description

[Detailed Description of the Invention] The present invention provides a method for coiling wires such as wires and electric wires supplied from a coiler into wire receivers such as packets and stems, by cutting the wires at the end of coiling. This invention relates to a coiler device equipped with an automatic cutter 20.

In a coiler system, when the wire receiver under the coiler becomes full, it is necessary to replace it with an empty wire receiver.
Conventionally, this type of wire holder replacement work involves closing the shutter 25 of the coiler when the wire holder is full, manually moving the full line holder, cutting the wire with scissors, etc., and removing the empty wire holder. This is done by placing the coil in a fixed position under the coiler, opening the shutter, and restarting coiling. The reason why wire receivers have to be replaced in such a way is due to the lack of development of automatic cutters for cutting wires.

In order to automatically cut the wire hanging down from the coiler, the position where the wire will fall cannot be determined, so this needs to be addressed. In order to cut the wire most reliably automatically, it is preferable to use a scissor-like automatic cutter with a blade length 35 slightly longer than the diameter of the coiler, since it can cover the entire area where the wire falls. However, automatic cutters with such long blades have the disadvantage of being very costly. SUMMARY OF THE INVENTION An object of the present invention is to provide a coiler device with an automatic cutter that can reliably cut wire even with a small blade and has a simple structure. Hereinafter, specific examples of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the automatic cutter and coiler device of this embodiment has a rotating body 2 that is rotatably supported by a bearing 1 with the axis of rotation oriented vertically. death,
The rotating drum 2 is rotatably driven by a motor 6 via a pulley 3, a belt 4, and a pulley 5. A wire 7 is supplied from above to the axis of the hollow rotating body 2, and a turn sheep 8 supported midway through the rotating body 2 connects this line 7.
Its direction is bent by 90 degrees so that it is led out from the rotary cylinder 2 in the radial direction. Ring-shaped forming tubes 9 are concentrically arranged at predetermined intervals around the outer periphery of the rotary drum 2 and are supported by a fixed support (not shown). The rotary cylinder 2 has a forming roller 1 that is in contact with the inner circumferential surface of the forming cylinder 9 and revolves while rotating.
0 is rotatably supported, and the wire 7 led out through the turn sheep 8 is sequentially pressed against the inner circumferential surface of the forming cylinder 9 to be formed into a coil shape. A guide pipe 11 is supported on the rotary cylinder 2 through a bracket 12 adjacent to the forming roller 10, and guides the formed line 7 downward. These bearings 1 to motor 6,
The components of the turn sheave 8 to the bracket 12 form a coiler main body 13. Wire 7 formed into a coil shape
slides down the outer periphery of rotating body 2 and is installed on the lower side.
．． -The coil is picked up by a wire receiver such as a bucket. Molding tube 9
A plurality of shutter shafts 14 are disposed at regular intervals in the circumferential direction on the outer periphery of the shutter shaft 14 via brackets 14, and are rotatably supported vertically.

A line stop 15 is fixed to the lower end of each shutter shaft 14 in a horizontal direction so as to be able to rotate five times under the rotary drum 2, and is driven by a drive source (not shown). The shutter shaft 14, wire stopper 15, drive source, etc. constitute an automatic shutter 16. When the automatic shutter 16 is closed by protruding each wire stop 15 toward the lower position of the coiled drop 4 of the wire 7, the wire 7 is accumulated in a coil shape on each wire stop 15, and the wire 7 is prevented from falling. When the wire stopper 15 is moved back from the coiled fall position of the wire 7 and the automatic shutter 16 is opened, the accumulated wire 7 will be coiled in a bucket or the like below.

A hook-shaped hook portion 1 is provided at one location on the outer circumference of the rotating body 2.
A movable blade 17 having a diameter of 7A is disposed so as to be movable in the radial direction of the rotary barrel 2 with its hook portion 17A facing upward (including diagonally upward), and is reciprocated by a reciprocating drive means 18 consisting of an air cylinder. It is becoming more and more popular. A fixed blade 19 is installed at a position where the movable blade 17 engages when the movable blade 17 retreats from the coiled wire dropping position, and cuts the wire 7 hooked by the movable blade 1r. Reciprocating drive means 1
8 and the fixed blade 19 are both supported by a fixed support body 20. In order to detect the operation timing of the reciprocating drive means 18, the line 7
A full winding sensor 21 detects that a wire receiver such as a bucket is fully wound by measuring the length or weight of the wire, and a wire falling position sensor 22 detects the falling position of the coiled wire 7. is provided. The detection signals of the sensors 21 and 22 are applied to an AND circuit 23, and the AND circuit 23 is configured to issue an operation command to the reciprocating drive means 18 and the like when both input signals are received. The line fall position sensor 22 is connected to a proximity switch 22A supported by a fixed support (not shown).
and a reaction plate 22B attached to the rotating body 2, and the reaction plate 22B is adjusted to a position related to the installation position of the movable blade 17 and the position of the guide pipe 11 (the position is determined by experiment). After installed. These movable blades 1
The automatic cutter 24 is composed of the components consisting of the AND circuit 23. Next, the operation of the automatic cutter 24, which forms the essential part of the present invention, will be explained.

The coiled wire 7 accumulates in a wire receiver such as a bucket,
The full volume sensor 21 continuously outputs a detection signal. In this state, when the reaction plate 22B rotates to the position of the proximity switch 22A as the rotating drum 2 rotates, the line falling position sensor 22 outputs a detection signal, and both input signals of the AND circuit 23 are aligned, so the AND circuit 23 issues operation commands. In response to this operation command, the automatic shutter 16 is closed, and at the same time, the movable blade 17 of the automatic cutter 24 is projected to the position where the coiled wire falls. Then, the wire 7 is caught on the wire stop 15 at the fixed position of the automatic shutter 16 (near the S position in FIG.
Since the position of B has been adjusted, the wire 7 caught on the wire stopper 15 rides on the movable blade 17. While the line 7 goes around once from this position (approximately 0.4 seconds), the movable blade 17 retreats under the control of a timer (not shown), and at this time, the movable blade 17 is pulled by the hook portion 17A of the movable blade 17. The wire 7 that is hung and carried together is cut by meshing with the movable blade 17 at the position of the fixed blade 19. The lower part of the cut wire 7 falls onto the full wire receiver directly below. When cutting and folding, the line 7 passes near the S position according to the line fall position sensor 22, so it is likely to fall. If there were no sensor 22, the automatic shutter 16 would randomly capture line 7, and if line 7 was passing near the T position at that time, the automatic shutter 16 and the automatic cutter 24 would operate almost simultaneously. Therefore, the wire 7 will ride on the automatic shutter 16 more than once before being cut. For this reason, even if wire 7 is cut, its lower end will not fall onto the full winding receiver, and in worse cases it will fall onto the blank wire receiver, causing wire 7 to straddle between both wire receivers, resulting in poor winding condition. This will lead to The fully wound wire receiver is moved by a conveyor (not shown), and while the automatic shutter 16 is closed, an empty wire receiver is transferred by the conveyor and positioned directly below the coiler body 13. In this state, the automatic shutter 16 opens and the coiled wire 7 that has been accumulated thereon begins to fall, and the coiling begins to take place in the empty wire receiver. In addition, automatic shutter 16 and automatic shutter 2
Although the operation timing with 4 is described as simultaneous in the above embodiment, it is possible that multiple wires 7 are overlapped and are not cut, and the cut lower wire 7 is accumulated in the automatic shutter 16. If not, the operation timing may be shifted as appropriate.

In the present invention, the term "full winding" includes not only the time when the wire receiver is literally full, but also the time when the required wire length or amount has been reached, although it is not literally full winding.

As explained above, in the coiler with one cutter device according to the present invention, the full winding sensor outputs a detection signal, and the line falling position sensor detects the falling position of the line along the circumferential direction of the forming cylinder when the movable blade is installed. Since the automatic cutter operates only when it detects that it is near the position and issues a detection signal, it waits at a specific position for the falling line while rotating along the inner circumference of the molding cylinder. It can be reliably captured and cut on the movable blade.

Further, in the present invention, the means for guiding the wire onto the movable blade is performed by the forming cylinder and forming roller of the coiler device, so there is no need to provide any special guiding means, and the structure can be simplified. Moreover, when the forming tube and forming roller guide the wire in this manner, the wire can be sufficiently captured and cut even if the movable blade and the fixed blade as the cutting means are downsized. Therefore, it is possible to reduce costs by simplifying and downsizing the device. Moreover, since the movable blade has an upwardly directed line hooking portion, the line placed on the movable blade will not come off before cutting, and the line can be cut reliably. Furthermore, in the present invention, since the coiler body is of a type in which the wire is formed into a coil shape using a forming tube and a forming roller and then dropped, the falling position of the wire can be easily detected with a wire falling position sensor. can.
