- Such a feeding device may be broken like a transport system or a reciprocating device.
- the belt conveyor type feeding device is suitable for long-distance conveyance at a low price, but the conveyance speed is slow compared to others where the positioning accuracy of the conveyed object is low.
- the belt conveyor requires a large installation space that is proportional to the transport distance.
- the screw-type feeding device uses a ground ball screw to improve the conveyance accuracy, and also enables conveyance at medium and high speeds.
- the force becomes a cost push factor, and the device becomes expensive.
- the screw-type feeder is not space-saving, it will be difficult to carry long distances like a belt conveyor because of its short force and short conveying distance.
- the cylinder-type feeding device has the problems of long-distance conveyance and high cost, and the compactness that can be said to be a space-saving type has not been achieved.
- the cylinder-type feeder has a practical difficulty in that it is difficult to arbitrarily change the transport stroke.
- the timing belt type feeding device is less expensive than the screw type feeding device using an abrasive ball screw, but it is considerably more expensive than a belt conveyor when using a high precision product for high positioning accuracy.
- the timing belt can be set to a longer transport distance than the screw feeder and the cylinder-type feeder. However, there are restrictions on manufacturing and the belt may be loosened, so the transport distance of the belt conveyor is secured. It is difficult.
- the timing belt type feeding device is not as long as the belt conveyor, but the conveyance distance is shortened accordingly.

Therefore, from this point of view, the dimension between the bearings of the rotating body should not be shortened! As long as it is not possible to achieve more precise and high precision feeding.
- the one that shifts the drum for the front and the reverse winder in the axial direction simultaneously with the rotation corresponds to the shift amount. This makes it more difficult to solve this problem because the dimensions between the bearings must be increased accordingly. Therefore, the above proposed example This type of feeder also requires new technical improvements from the viewpoint of suppressing this type of increase in dimensions as much as possible.

- the winding linear bodies adjacent to each other on the drum peripheral surface are rubbed or overlapped, and an excessive twisting force is applied, causing the linear bodies to fatigue early.
- the proposed example does not disclose a technique for avoiding such a problem.

Therefore, the reciprocating operation body 71 is fed in the direction opposite to the arrow R 1 direction, and the reciprocating operation body 71 moves to the left in FIGS. 1 and 2 while being guided by the guide means 82.
- the drum 37 of the forward / reverse winder 31 when feeding the reciprocating body 71 as shown in FIGS. 1 to 3 is controlled by the leads of the female screw 39 and the male screw 43.

- the guide pulleys 83 and 85 located near the drum 37 will give good results when both linear bodies 51 and 61 are wound or unwound by rotation of the forward / reverse winder 31. Become. This is because the winding linear body part S1 of the two linear bodies 51 and 61 wound around the drum 37 and the guide linear body part S2 extending over the pulleys 83 and 85 maintain a parallel relationship. This is because the pulleys 83 and 85 are arranged so that the parallel relationship can be maintained. As a result, both linear bodies 51 and 61 are precisely wound around the drum circumferential surface of the forward / reverse winder 31 at a uniform pitch and are rewound.
- the two linear bodies 51 and 61 that maintain the parallel relationship also prevent the adjacent winding linear body portions from rubbing and overlapping with each other on the drum circumferential surface of the forward / reverse winder 31 and excessive twisting force. Therefore, the fatigue life of both the linear bodies 51 and 61 can be avoided and the life of the linear bodies 51 and 61 can be increased. In particular, the prevention of rubbing between the winding wire bodies also contributes to dust generation prevention measures.
- the wire body 51 for normal winding and the wire body 61 for reverse winding in the embodiment of FIGS. 1 to 3 are term names simply given in a relative relationship. Therefore, even if the terms are changed such as “straight wire 61” or “reverse winding wire 51”, the substantial content does not change.
- both linear bodies 51 and 61 are excessively displayed and the reciprocating body 71 is excessively displayed. I can understand that it works.
- the horizontal structure is as shown in the figure, but when the reciprocating body 71 is fed in the vertical direction.
- the guide means 82 may be given a gradient when the reciprocating body 71 is fed in an inclined direction.
