Niputuslaitejärjestely. - Anordning vid buntningsaggregat.

The present invention relates to a bundling device arrangement for bundling small timber, such as woodpecker, wood waste and the like, in connection with clearing, thinning, road clearing, fire clearing, fields, streams, lakes, streams, rivers and roadside clearing. an inlet opening through which the small timber is fed into the compression chamber.

Such known devices have been shown to have drawbacks which cause a time-consuming feed of the pressing device itself, whereby the efficiency deteriorates.

It is therefore an object of the present invention to provide an apparatus for improving the efficiency of bundling of small timber.

This task is solved in such a way that a shutter and press member can be placed in front of the inlet opening to close the opening and press the small timber into a pressing space which, when said member is in front of the inlet opening, decreases to compress the small timber fed into it. The front of the closure and compression member can pivot into and out of the inlet. A break portion is provided in the front of the closure and press member. The pivoting part extends obliquely from the surface facing the inlet opening towards the cutting part, whereby the pressing and bundling member tapers towards the cutting part. The shape of the compression space is, as it were, part of an elongate cylinder sector, the arcuate walls of which pivot about an axis in the middle of the cylinder to open and close the inlet opening, the compression and bundling member being axially displaceable into and out of the inlet opening. The surface of said member facing the inlet opening has essentially the same curvature as the cylinder.

The present invention provides a device which greatly enhances the supply of small timber to a bundling device. After the pressing space has been filled in a conventional manner, e.g. by means of a feed table and one or more rotating feed rollers, a closing and pressing member is pushed in front of the inlet opening in place in front of the inlet.

The features of the invention appear from the claims.

The invention will now be explained in more detail with reference to the accompanying drawing, in which:

Figure 1 schematically shows a cross-section of a bundling arrangement provided with a device according to an embodiment of the invention, and

Figure 2 is a top plan view of parts of the devices shown in Figure 1.

The bundling arrangement shown in Fig. 1 may be as shown in Swedish patent application 7907879-6 and comprises an elongate cylinder 1 and a circumferential groove 2 extending along the cylinder and forming an inlet opening in the compression space 3 formed by two mutually pivotable parts 5 and 6. The cylinder 1 may be well provided with a similar feed opening and a corresponding compression space on the opposite side of the cylinder 1. The cylinder 1 can be rotated so that the compressed and bundled small wood product can be fed out of the compression space 3 from a different place than the feed opening 2, and during the discharge from the compression space 3, ties or straps can be attached to hold the compressed bundle together. In one case, it may be suitable for the casing 3 74192 to be fed out after the cylinder 1 has rotated half a turn, in which position the pressed bundle is pushed out of the pressing chamber 3 by a piston or similar device projecting in from one end, a binding device when feeding it out of the compression chamber. Fig. 1 shows, in broken lines, at the feed opening 2, how the opening closes when the parts 5 and 6 turn against each other during the pressing of the small timber fed into the pressing space 3. In order to facilitate the feeding of small timber into the pressing space 3 through the opening 2, the pressing and pushing part 7 is pushed by a suitable device into a position in which the entire inlet opening 2 is free. In this position, the device 7 is located further to the left than in the position shown in Fig. 2. The device 7 can be controlled by sliding and guide rails (not shown) and the device 7 can also be provided with rollers for guiding it on the rails. The transfer of the device 7 can take place by means of conventional operating means, such as chains or a piston and cylinder device.

As can be seen from Fig. 1, the pressing space 3 is filled by placing small timber on a table 8, which may be provided with conventional feeding means for feeding small goods to the table and pressing space 3. A feed roller can be arranged above the table 8 to rotate and turn against the table 8. away, as illustrated by the dashed lines. Both the feed table 8 and the feed roller or feed roller are conventional. When the roll is turned towards its compression space 3 during its rotation, the small timber is compressed into that space through the feed opening 2. When the space 3 is full, the parts 5 and 6 are turned against each other, but before that the feed opening 2 and the compression space 3 must be closed and the small timber fed into the space 3 must be separated from the small timber still on the table 8. This is done by pushing the pressing and closing member 7 from its rest position in front of the feed opening 2. The side of the part 7 facing the opening 2 is curved in the same way as the cylinder 1 and at the front the device or member comprises a cutting part 9, which may be knife blade, but a chain saw with a saw chain arranged perpendicularly proven to be particularly effective. 7 to separate the small timber already fed into the pressing space 3 from the small timber stacked on the table 8.

In addition, the pressing member 7 is provided with a pivoting front part 10 so that the member 7 becomes sharp and wedge-shaped, in which case the extra small timber is pressed into the space 3 during insertion of the device 7 when the device 7 is inserted and covers almost the entire feed opening 2. so that the pivoting part 10 pivots away from the position shown in Fig. 2 to the position shown in broken lines, whereby all the separated small timber is compressed into the space 3, after which the parts 5 and 6 can be pivoted to compress the fed timber. The turning of parts 5 and 6 can take place in different ways, but hydraulically driven piston and cylinder braces have proven to be effective. After the parts 5 and 6 have been turned against each other and the small timber has been pressed in the space 3, the cylinder 1 can be turned half a turn to the outlet point, and in this case the cylinder 1 can be provided with additional fastening parts 5, 6 so that the new pressing space 3 can be filled while the full compression space is emptied and the compressed bundle is tied. The pivoting part 10 may be spring-loaded, but as soon as the device 7 has reached its rest position, said part pivots to the position shown in solid lines in Fig. 2.
