Description
CA 022~4446 1998-11-19 Apparatus for feeding bunches into a strander or the like The present invention relates to an apparatus for feeding untied bunches, 5 consisting of a number of roundwood logs or the like, while maintaining a sub-stantially bunched-up condition, in the direction of the longitudinal axis of the bunch, intermittently into a strander or the like.
There are mechanisms in the prior art, wherein a pusher, equipped with a push 10 plate and applying a force to the end of a bunch, or a conveyor present under-neath a bunch is used for carrying the bunch into a strander. Hence, a problem with the prior known mechanisms is that the bunch does not retain its wholeness or intactness but the logs present therein move relative to each other, the bunch breaking up in its lateral or longitudinal direction. This, in turn, has a conse-15 quence that the capacity of a strander cannot be exploited to full extent.
An object of the invention is to provide an apparatus, whereby a bunch or to befed into a strander or the like is maintained intact and compact as well as possi-ble in order to provide the strander with a degree of loading as high as possible, 20 in other words, the apparatus is supplied with as much timber as possible and as little air as possible.
According to the invention, this object is achieved and an apparatus of the invention is characterized in that said apparatus includes at least one intermittent 25 feeder, mounted on the supply line of the apparatus and adapted to grab a bunch present on the supply line for carrying the same through a fixed distance in the feeding direction of said supply line, and said intermittent feeder beingprovided with at least one gripper element, applying the actual feeding move-ment to the bunch and compressing the bunch for the duration of its passage 30 crosswise relative to the lengthwise direction of the bunch, for eliminating relative movement between roundwood logs or the like present in the bunch during the course of a passage.
CA 022~4446 1998-11-19 In one preferred embodiment of the inventionj the arrangement is such that the apparatus additionally includes a feeding device for feeding a bunch into the range of one or more intermittent feeders.
5 In one preferred embodiment of the invention, the arrangement is such that theapparatus includes at least two intermittent feeders, mounted successively on the supply line of the apparatus. Thus, the arrangement is preferably such that at least the intermittent feeder furthest away from a strander is adapted to be set, independently of other intermittent feeders, for a desired period in a position in 10 which the gripper element or elements of the intermittent feeder remain in anopen position. This is important, especially when there is no continuing flow ofbunches of wood towards a feeding device which carries the bunch further into the operating range of one or more intermittent feeders and, thus, whereby the feeding device does not always contain a bunch ready for feeding. When the 15 intermittent feeder furthest away from a strander is in an open position and there is no bunch in line therewith, a high-speed action can be used to supply this intermittent feeder with a fresh bunch following the preceding one, while at thesame time, the other intermittent feeder or feeders continue the intermittently proceeding feeding action. This makes it possible to have bunches of wood 20 available for feeding into a strander without down-times.
Other preferred evolutions of the invention are set forth in the non-independentclaims.
25 The invention will now be described in more detail by way of an example with reference made to the accompanying drawing, in which:
fig. 1 shows an apparatus according to one embodiment of the invention in a schematic lateral view.

Fig. 4 shows an apparatus according to a second embodiment of the invention in a section similar to fig. 2.
Fig. 5 shows a section similar to fig. 4, with the gripper elements of an intermittent feeder in a clamping position thereof.
Fig. 6 shows the apparatus of figs. 4 and 5 in a lateral view.
Fig. 1 of the drawing depicts in a schematic lateral view an apparatus accordingto one embodiment of the invention for feeding untied bunches 1, consisting of anumber of roundwood logs or the like, while maintaining a bunched-up condition 15 as compact as possible, in the direction of the longitudinal axis of the bunch, intermittently into a strander 2 or the like.
In the exemplary embodiment shown in fig. 1, the apparatus includes two inter-mittent feeders 3, 4, mounted on a common frame structure 12 successively 20 along the apparatus supply line. The feeders 3, 4 are adapted, optionally either one or both together, to grab the bunch 1 present on the supply line for carrying the same through a fixed distance a in the feeding direction of the supply line.The distance a is preferably selected to match a length that can be fed into thestrander 2 at one time. The feeders 3, 4 are shown in a basic position thereof 25 with solid lines. In addition, the left-hand end of the feeders 3, 4 is shown with dashed lines in one of the end positions thereof.
Each of the intermittent feeders 3, 4 is provided with at least one, in fig. 1 with two gripper elements 5, applying the actual feeding movement to the bunch 1 30 and compressing the bunch for the duration of its passge, for eliminating relative movement between roundwood logs or the like present in the bunch 1 during the course of a passage.
.. . . .
CA 022~4446 1998-11-19 In fig. 1, to the right of the intermittent feeders 3, 4 is a loading trough 11, which is supplied with the bunches of wood 1 one bunch at a time and from which trough a feeding device 17 delivers the bunch 1 into the operating range of one or more intermittent feeders 3, 4. By means of the intermittent feeders 3, 4, the 5 bunches 1 proceed forward into the strander 2, shown schematically in the left-hand portion of fig. 1, as required by its operation.
The intermittent feeder 3 furthest away from the strander 2 can be set, independ-ently of the intermittent feeder 4, for a desired period of time in a position, 10 wherein the gripper element 5 remains in an open position. Thus, the pusher 17 can be used for quickly moving a fresh bunch to the back of a preceding bunch present only within the operating range of the intermittent feeder 4, whereafterboth intermittent feeders 3, 4 may continue their action concurrently and together in a controlled manner. It should be appreciated, however, that the intermittent15 feeders 3, 4 can be adapted to be controlled for operating independently of each other, whereby e.g. the upstream intermittent feeder 3 can be controlled in sucha manner that the bunches 1 are set closely one after the other in good order.
In order to secure a continuing wholeness and precise guidance for the bunches, 20 each intermittent feeder 3, 4 is provided with at least two gripper elements 5. The gripper elements 5 are adapted to travel back and forth through the distance a along guides 16 mounted on the frame structure 12. Said feeding movement is achieved by means of hydraulic cylinders 15, one end of the hydraulic cylinder being secured to the solid frame structure 12 of the intermittent feeder 3, 4 and 25 the other end to a frame portion of the gripper element 5.
With the intermittent feeders 3, 4 in a basic position thereof, as depicted withsolid lines in fig. 1, the gripper elements 5 grab the bunch 1, present on the supply line and resting on fixed supports 10, 20 attached to the frame structure30 12 of the apparatus, and lift the bunch 1 and carry it through the distance atowards the strander 2. At the end of a feeding movement, the gripper elements 5 release the bunch 1 back on the fixed supports 10, 20, whereafter the gripper elements 5 return back to the initial position thereof.

CA 022~4446 1998-11-19 The frame portion of a gripper element 5 comprises a lattice structure, which isadapted to travel back and forth through the distance a and which lattice struc-ture includes side beams 6, 7, a lower beam 22, and an upper beam 23. In the embodiment shown in figs. 2 and 3, the gripper element 5 is provided with an 5 upper jaw 8 and a lower jaw 9, said jaws being adapted to travel in a substan- tially vertical direction relative to the lattice structure.
In the exemplary embodiment of figs. 2 and 3, the upper jaw 8 and the lower jaw 9 are constituted by beams, which are movably journalled at the ends thereof to 10 the side beams 6, 7. Furthermore, the lower jaw 9 includes a u-shaped bearing surface 28 for the bunch 1.
In view of operating the upper jaw 8, there is arranged a hydraulic cylinder 13,one end of which is attached to the upper beam 23 and the other end to the 15 upper jaw 8. respectively, in view of operating the lower jaw, there is arranged a hydraulic cylinder 14, one end of which is attached to the lower beam 22 and theother end to the lower jaw 9.
In the exemplary embodiment of figs. 4 and 5, the gripper element 5 is provided 20 with side jaws 18, 19, said jaws being adapted to travel in a substantially horizon-tal direction relative to the lattice structure making up the frame portion of the gripper element 5. Thus, the side jaws 18, 19 are journalled in a per se known fashion to travel within slots made in the upper beam 23 and the lower beam 22.
Both jaws 18, 19 are provided with a u-shaped bearing surface 29 open towards 25 each other for pressing the bunch 1 between said jaws. A schematic lateral view, corresponding to figs. 4 and 5, is depicted in fig. 6.
In view of operating the side jaw 18, there is arranged a hydraulic cylinder 24,one end of which is attached to the side beam 6 and the other end to the side jaw 30 18. Respectively, in view of operating the other side jaw 19, there is arranged a hydraulic cylinder 25, one end of which is attached to the side beam 7 and the other end to the side jaw 19.
CA 022~4446 1998-11-19 The apparatus further includes a number of fixed supports 10, 20, on which the bunch 1 is adapted to be rested for the duration of a return action performed bythe intermittent feeder 3, 4. The fixed supports 10, 20 are constituted by plate-like elements, mounted crosswise along the supply line of the intermittent 5 feeders 3, 4 on the fixed frame structure 12 common to the apparatus. In the solution of figs. 2 and 3, the support plate 10 is designed to include a u-shaped bearing surface 26 and in the solution of figs. 4 and 5, respectively, the support plate 20 is designed to include an oblong bearing surface 27.
10 The gripper elements 5 are adapted to bring the bunch 1 off the fixed supports 10, 20 for the duration of a feeding movement performed by the intermittent feeder 3, 4. Therefore, the u-shaped bearing surface 28 of the lower jaw 9 (figs.

CA 022~4446 1998-11-19 In fig. 1, to the right of the intermittent feeders 3, 4 is a loading trough 11, which is supplied with the bunches of wood 1 one bunch at a time and from which trough a feeding device 17 delivers the bunch 1 into the operating range of one or more intermittent feeders 3, 4. By means of the intermittent feeders 3, 4, the 5 bunches 1 proceed forward into the strander 2, shown schematically in the left-hand portion of fig. 1, as required by its operation.

The gripper elements 5 are adapted to travel back and forth through the distance a along guides 16 mounted on the frame structure 12. Said feeding movement is achieved by means of hydraulic cylinders 15, one end of the hydraulic cylinder being secured to the solid frame structure 12 of the intermittent feeder 3, 4 and 25 the other end to a frame portion of the gripper element 5.
With the intermittent feeders 3, 4 in a basic position thereof, as depicted withsolid lines in fig. 1, the gripper elements 5 grab the bunch 1, present on the supply line and resting on fixed supports 10, 20 attached to the frame structure30 12 of the apparatus, and lift the bunch 1 and carry it through the distance atowards the strander 2. At the end of a feeding movement, the gripper elements 5 release the bunch 1 back on the fixed supports 10, 20, whereafter the gripper elements 5 return back to the initial position thereof.

CA 022~4446 1998-11-19 The frame portion of a gripper element 5 comprises a lattice structure, which isadapted to travel back and forth through the distance a and which lattice struc-ture includes side beams 6, 7, a lower beam 22, and an upper beam 23. In the embodiment shown in figs. 2 and 3, the gripper element 5 is provided with an 5 upper jaw 8 and a lower jaw 9, said jaws being adapted to travel in a substan- tially vertical direction relative to the lattice structure.
In the exemplary embodiment of figs. 2 and 3, the upper jaw 8 and the lower jaw 9 are constituted by beams, which are movably journalled at the ends thereof to 10 the side beams 6, 7. Furthermore, the lower jaw 9 includes a u-shaped bearing surface 28 for the bunch 1.
In view of operating the upper jaw 8, there is arranged a hydraulic cylinder 13,one end of which is attached to the upper beam 23 and the other end to the 15 upper jaw 8. respectively, in view of operating the lower jaw, there is arranged a hydraulic cylinder 14, one end of which is attached to the lower beam 22 and theother end to the lower jaw 9.
In the exemplary embodiment of figs. 4 and 5, the gripper element 5 is provided 20 with side jaws 18, 19, said jaws being adapted to travel in a substantially horizon-tal direction relative to the lattice structure making up the frame portion of the gripper element 5. Thus, the side jaws 18, 19 are journalled in a per se known fashion to travel within slots made in the upper beam 23 and the lower beam 22.
Both jaws 18, 19 are provided with a u-shaped bearing surface 29 open towards 25 each other for pressing the bunch 1 between said jaws. A schematic lateral view, corresponding to figs. 4 and 5, is depicted in fig. 6.
