Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is provided with an endless rotation band that receives and sends a binding discharge straw that is fed laterally from a binding device and that is fed by this endless rotation band. The present invention relates to a discharge straw bundle three-dimensional discharge device that discharges and discharges discharge straw in a vertical posture in which its stock source is directed downward.

[Conventional technology]

Conventionally, as an exhausted straw bundle three-dimensional discharging device configured as described above, there is one shown in, for example, Japanese Patent Laid-Open No. 57-74018, and in this reference, the endless rotation band is composed of an endless chain and the combine In the rear view of the vehicle body, the endless rotation band is provided by setting the rotation axis of the sprocket around which the endless chain is wound at an angle of about 45 degrees with respect to the horizontal.

[Problems to be Solved by the Invention]

In other words, by setting the attitude of the endless chain as described above, the endless chain receives the binding waste straw in the lateral posture from the binding device at its front part and changes the attitude of the binding waste straw during conveyance. In the rear part, however, the bundled discharge straws are configured to be discharged in a vertical posture.

However, when the posture of the endless chain is set in this manner, the endless chain is bundled in a posture inclined by about 45 degrees with respect to the conveying surface (the surface formed substantially parallel to the axis of the sprocket). Receives the bundle discharge straw from the device, and
Similarly, since the bundled discharge straws are discharged in a posture inclined by about 45 degrees with respect to the transport surface of the endless chain, a transport failure may occur at the front part and the rear part of the transport system including this endless chain. There is room for improvement.

Further, when the endless rotation band is formed of an endless chain as in the above-mentioned reference, the posture of the bundling and discharging straw is changed only by the weight of the bundling and discharging straw, which makes it difficult to smoothly change the posture. There is room for improvement.

It is an object of the present invention to send a bundle discharge straw without causing a force shortage in the entire area of a conveyor system consisting of an endless rotation band by rational modification, and to smoothly change the posture of the bundle discharge straw in the conveyor system. Another point is to obtain an exhaust straw bundle three-dimensional emission device in which these operations are favorably maintained.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the discharged straw bundle three-dimensional discharge device is provided with an endless rotation band for receiving and sending the bundled discharge straw sent in a horizontal position from the binding device. In the discharge straw bundle three-dimensional discharge device for dropping and discharging the bundled discharge straw in a vertical posture in which the root of the stock is directed downward, the endless rotation band is formed in a strip plate shape, and the endless rotation band is wound. The axis of rotation of the wheel body on the upper hand side of conveyance is set substantially laterally, and the axis of rotation of the wheel body on the lower hand side of conveyance is set substantially vertically, and the endless rotation is performed with respect to these two wheels. The band is wound in a state of being twisted by about 90 degrees, and the endless rotation is performed on a strip plate-shaped guide member that faces the back side of the transport surface of this endless rotation band and determines the posture of the transport path side. A guide portion for preventing lateral displacement of the belt is formed so as to project, and this guide member is attached to the endless rotation belt. And along a feeding plane so that others are formed into a shape twisted approximately 90 degrees, its action and effects are as follows.

[Work]

When the above features are configured as shown in, for example, FIG. 1, FIG. 2 and FIG. 4, the endless rotation band (13) is a band plate having a surface in the crucible direction and the carrying direction of the bundle discharging straw to be carried. In addition, since the end face of the endless rotation band (13) faces in the vertical direction at the front part of the transfer system and faces in the left and right direction at the rear part of the transfer system, The bundling / discharging straw (5) sent by 13) runs along the transport surface of the endless swivel belt (13) from the initial horizontal posture to the vertical posture, and thus it is less likely that a defective transport will occur, and the endless rotation will not occur. When the moving belt (13) is transported, the orientation change direction of the transport surface is the binding discharge straw (5)
Since it coincides with the posture change direction of No. 3, it does not take time and effort to adjust the position of the holding rail with respect to the endless rotation band (13) so that the posture can be changed by the weight of the bundle discharge straw (5) as in the conventional case. The posture of the bundle discharge straw (5) can be changed only by disposing the holding rail (14) in a fixed positional relationship with the endless rotation band (13).

Even when the endless rotation band (13) is twisted in this way, since the guide portions (18a) and (18a) are formed on the guy member (18), the endless rotation band (13) is formed. ) Horizontal deviation is prevented.

〔The invention's effect〕

Therefore, the bundle discharging straw is sent without causing a force shortage in the whole area of the conveying system composed of the endless rotating belt, the posture of the bundle discharging straw is smoothly changed by the conveying system, and the endless rotating belt is guided by the guide member. Since the posture of the device is stable, the discharged straw bundle three-dimensional emitting device in which these operations are favorably maintained was obtained.
