With regard to the state of the art of the present invention, reference is made to the applicant's FI patent No. 42 188, which discloses a transfer device for lumber handling, stapling and bundling devices, which transfers a layer formed of adjacent pieces of lumber as a whole. This transfer takes place in such a way that the relative position of the sawn timber pieces does not change during the transfer. This device comprises parallel, spaced-apart transfer brackets that are movable along their length. The transfer brackets are rotatable in an oblique position about an axis parallel to their length. The operation of the transfer supports is arranged periodically so that when they receive the sawn timber layer transverse to their support, they rotate about an axis along their longitudinal axis to a certain angle of inclination and then move the sawn timber layer in the direction of their longitudinal axis to a certain distance. The transfer carriers are then turned back to the original inclination position and retracted to the starting position, at the same time releasing the sawn timber layer from the transfer carriers, after which the transfer carriers return to the starting position for moving the next sawn timber layer.

In the arrangement according to said FI patent No. 42 188, the transfer bracket is mounted for rotation in a pivot center and the transfer bracket is rotated between the desired positions by means of a lifting lever on the side (Figures I and II of the patent). However, this known method of rotation has made the equipment complicated and expensive, since each lifting rod must have its own lifting cylinder which has moved in its base with the transfer supports.

In a known application, the lifting rods are attached to a transverse heavy beam structure which moves with the transfer supports with its lifting rods. This is also an unfavorable solution.

It is an object of the present invention to provide a new, simple and safe drive device for rotating and moving transfer carriers.

In order to achieve the above and later objects, the invention is mainly characterized in that said guides further act as actuators for rotating about the longitudinal axis of the transfer carriers.

The invention will now be described in detail with reference to some embodiments of the invention shown in the figures of the accompanying drawing, to the details of which the invention is in no way narrowly limited.

Figure 1 schematically shows a first embodiment of the invention seen from the side.

Figure 2 shows section II-II in Figure 1.

Fig. 3 shows a second embodiment of the invention in a manner similar to Fig. 1.

Figure 4 is a section IV-IV in Figure 3.

Figure 5 shows an embodiment of the invention using two alternating sets of transfer carriers.

Figure 6 shows a section VI-VI in Figure 5.

Figures 7a, b, c, d and e show some alternative arrangements between the transfer carrier carriage and its slide.

The transfer devices shown in the figures transfer layers K 1 from the timber mat to a package P, which is formed on elevator supports 10, which descend as is known per se as the timber package P grows. The layers K 1 are taken from the incoming conveyor, the chains of which in Fig. 2 are denoted by reference numeral 11.

Figures 1-4 show three parallel slirt carriers 12. The transfer carriers 12 are attached at their rear ends to carriages 14 which reciprocate by elongate, horizontal guides 20. The reciprocating movement of the carriage 14 is effected by transfer chains 17 arranged between the swivel wheels 18 resting on the frames 19. The chains 17 are driven back and forth by the shaft 22 of the second swivel wheels 18 by the motor 23.

According to the invention, the guides 20 are connected at both ends by bearings 21 to the body 19 so that the guides 20 can be rotated about their longitudinal axis Γ 4 67346 for the purpose of turning the transfer translators 20 between their positions 12a and 12b shown in Figures 2 and 4. In position 12b, the transfer carriers 12 move the timber layer onto the package P and then turn to position 12a on their flaps, in which position the transfer carriers 12a can be pulled to the rear position, leaving the timber mat K 1 on the package P in order.

The transfer brackets 12 have a conveying surface 12 'at their narrower upper edge and their wider sides have smooth sliding surfaces. If necessary, the transfer supports 20 have a protrusion 13 to prevent the movement of the timber layer.

The other ends of the slides 20 are attached to the pivot sleeves 28 near the second bearing 21, with pivot members 27 connected by articulated pins to the arm 24. The other end of the arm 24 is connected to an actuator 25, e.g. a hydraulic or pneumatic cylinder, one end fixed to the body 26. 25, the guides 20 can be pivoted to pivot the transfer brackets 12 between positions 12a and 12b. For this purpose, the carriages 14 are connected to the slide guides 20 by an arrangement which transmits torque. Examples of these arrangements are shown in Figures 7, the details of which are described below.

According to Figures 1 and 2, each carriage 14 has its own transmission chain 17, to which the carriages 14 are connected by an annular part 15 and a fastening part 16, which allow the carriages 14 to turn under the action of the actuator 25. Contrary to the above, according to Figures 3 and 4, said ring parts 15 of the carriages 14 are connected to a connecting rod 30, which in turn is connected to the transmission chain 17 in the vicinity of both ends. Thus, for carriages 14, which may be very numerous, e.g. pair 17.

The embodiment of the invention shown in Figures 5 and 6 differs from that shown above in that, instead of one set of transfer carriers, this embodiment has two sets of transfer carriers, namely sets 120 and 121, which operate alternately. As shown in Figure 5, the timber layer is supported by the carrier set 120a, while the timber layer is transferred onto the timber package P and turned from the transfer arm assembly 121b to its flap, in which position the transfer arm assembly 121 is ready to retract to its starting position. The sets of transfer arms 120 and 121 are attached to their guides 20a and 20b as described above, on which the slides 14a and 14b described above slide. In order to reciprocate the two sets of carriages 14a and 14b, a special drive device is provided, comprising two sets of chains, namely sets of chains 17a and 17b, of which the set of chains 17a is arranged to run around the swivel wheels 18a. The latter Swivel wheels 18a are fixedly connected to a shaft 22a which is driven by a motor 23a as described above. The pivot wheels of the chain set 17a on the second shaft 22b are freewheels and the pivot wheels 18b of the chain set 17b on the shaft 22a are freewheels, respectively. Attached to the shaft 22b is a second drive motor 23b (not shown) corresponding to the motor 23a, which drives the swivel wheels of the chain set 17b. To pivot the two sets of transfer carriers 120 and 121 between their above-mentioned positions a and b, both sets of slide guides 20a and 20b are connected to the transfer rods 24a. The transfer rods 24a are driven by transfer devices 125 and 126 connected to the body portions 26.

According to Figures 7, the torque-transmitting arrangement between the carriage 14 and the guides 20 can be implemented in several different ways. According to Fig. 7a, the guide 20a 'is provided with a longitudinal groove 31 thereof with one or more rollers 32 to be fastened to the carriage 14. In addition, there are sets of balls 33 between the guide 20a' and the carriage 14.

As shown in Figures 7b, the guide 20b has three symmetrically spaced cantilever portions 34 with sets of balls 33 that transmit torque between the portions 20b and 14.

According to Fig. 7c, two opposite grooves 35 are made in the guide 20c, in connection with which ball rings 36 are arranged, which transmit torque between the parts 20c and 14.

According to Fig. 7d, the guide 20d has a hexagonal cross-section on flat sides and rollers 38 on the shafts 39 are mounted on the carriage 14 by means of flanges 40.

According to Fig. 7e, the guides 20e have three symmetrically spaced ball grooves fitted with sets of balls 33 which transmit torque between the parts 14 and 20e.
