Description

[Detailed description of the invention] The present invention provides a rotating body which acts on the tip side of the tied stem culm in a constantly driven state, and when the stem culm converges, the rotating body is put in a non-acting state and the stem culm is released. A receiving member is swingably provided in a non-working position where the rotary body is in a working state, and the receiving member is swingably biased to the non-working position when the stem culm is released, and when the stem culm converges. The present invention relates to a stem culm binding device which is provided with a spring mechanism for maintaining the receiving member in an operating position using a revolving door for a tied stem culm discharge port as a stopper.

The above-mentioned stem culm binding device applies a release action to the tip side of the tied stem culm using a rotating body, thereby achieving the following:
Consideration has been given to prevent the problem of the tip side remaining on the machine when the stem culm is released, which would occur when applying only to the stock side.
Furthermore, by placing the rotating body into a non-operating state using a stem culm receiver when the stem culm converges, the rotating body can be constantly driven, and the transmission structure thereof can be simplified. It is. However, conventionally, in order to quickly move the stem culm receiver to the non-operating position when the stem culm is released, the spring mechanism moves the stem culm receiver to the operating position. Even if there is, the structure is such that it is biased towards the non-acting position. As a result, as the revolving door and its abutting members wear out, the working position of the stem culm retainer shifts to the non-working position compared to the original position, causing the inconvenience that the rotating body acts when the stem culm converges. The disadvantage was that it occurred early.

The present invention enables the spring mechanism to quickly retire the stem culm retainer to the non-operating position, and even when the revolving door and the abutting member thereof are worn out, the stem culm converges when the stem culm converges. It is an object of the present invention to solve the above-mentioned drawbacks by modifying the culm holder into one that can reliably hold the culm holder in its working position.

According to the present invention, in the above-mentioned stem culm binding device, the spring mechanism 20 includes a first spring 21 that swings and biases the receiving member 17.
The receiving member 17 is provided so as to be swingable between a first state in which the receiving member 17 is biased to the working position and a second state in which the receiving member 17 is biased in the non-working position, and the first spring 21 is set in both the states. A second spring 28 is provided that urges the switching swinging member 24 to a position where the first spring 21 is in the second state, and the swinging member 24 is biased so that the first spring 21 is in the second state when the stem culm converges. It is characterized in that it is configured so that it is kept in contact with the revolving door 10 at the position where it is in the 1 state.

That is, when the stem culm is released, the first spring 21 switches to the second state, and the stem culm receiving member 17 is biased to the non-operating position, so that the stem culm receiving member 17 is displaced to the non-acting position. The first spring 21 urges the stem culm receiving member 17 to the operating position when the stem culm converges, while allowing the tied stem culm to be released without the tip side getting caught by the machine body. By being in the first state,
In addition, since the first spring 21 is of a type in which the biasing direction can be switched, even if the revolving door 10 and the swinging member 24 in contact with it are slightly worn out, the stem culm receiving member 24 will remain intact. It has become possible to prevent the stem from being displaced to the side of the non-operating position, and it has become possible to prevent the function of the stem culm receiving member 17 from being impaired at an early stage.

Next, embodiments of the present invention will be described based on the drawings.
