The invention relates to a stamping device for identifying a piece of timber or the like, in particular to a sorter of timber pieces, which device comprises a plurality of stamping units in which stamps are struck on timber or the like, the stamping device comprising a body part with a plate part the pieces of timber are adapted to pass and in which the plate part has at least two stamping points spaced apart, e.g. a stamping hole, and in which the device has a plurality of stamping arms articulated or respectively adapted to be rotated by actuators to provide a stamping movement.

The ends of the pieces of timber are stamped for several different purposes. Recently, there has been a need to stamp the end of a piece of timber during sorting with a stamp identifying the person who has carried out the sorting, which has proved necessary due to subsequent complaints about the quality of the timber.

With regard to the state of the art related to the invention, reference is made to Fi patent No. 35901, which discloses a wood longitudinal stamping device with a series of separate articulated lever arms provided with numbers or the like.

2 59361

All lever arms perform a stamping motion at the same location based on the stimulus they receive. If a stamping device such as the one described above is used to identify the sorter, then the device becomes quite complicated because a very large number of separate lever arms are needed, each provided with its own identifier for identifying the sorter.

It is an object of the present invention to provide a stamping device for the above use. It is a particular object of the invention to provide a stamping device which is as simple and reliable as possible in structure. Another specific object is to provide a stamping device which provides a sufficiently large number of different stamp combinations at the lowest possible device cost.

The invention is mainly characterized in that the device has at least two sets of stamping units, which sets stamp at different points.

The invention will now be described in detail with reference to an embodiment of the invention shown in the figures of the accompanying drawing, to which the invention is not limited.

Figure 1 schematically shows a device according to the invention as seen from the direction of the length of the pieces of timber to be stamped.

Figure 2 shows section II-II in Figure 1.

The stamping device shown in the figure consists of a body part comprising a top beam 10 and an arcuate beam 11. Attached to the top beam 10 is a plate part 23, past which the pieces of timber in the direction A pass so that their ends flank the outer surface of the part 23. The above-mentioned frame is attached to the body of the sorting conveyor by means of lugs 12. As shown in Figure 1, two sets of stamping units are attached to the body of the device radially with respect to the stamping holes 22A and 22B in the portion 23. The marking holes 22A and 22B are located at a small horizontal distance Δ ^ from each other. The distance Δ 1 is chosen so that, through both holes 22A and 22B, stamping can also be performed on the ends of even the narrowest pieces of timber, e.g. 75 mm wide. According to Figure 1, the units 31A, 32A.33A and 34A stamp through the hole 22A and the units 31B, 32B, 33B and 34B respectively through the hole 22B.

Figure 2 shows an implementation example of the structure of each stamping unit. Units 31-34 include a stamping arm 13 articulated by a shaft 14 in connection with a portion 23. Attached to the arm 13 by an articulation pin 15 is a piston 17 or similar piston

Claims (2)

59361 a nipple arm 16 by means of which the arm 13 can be pivoted at an angle α about its axis 14. The arm 13 is shown in two positions; with a full line in the position where the stamping is performed and with dotted lines in a position 13 'where the arm 13' is turned to a position where the arm 13 'is against a flange 24 fixed to the beams 25. Said flange 24 as well as the inner surface of the part 23 at the marking holes 22A.22B are provided with a flexible part 20 resp. 21 to absorb shocks. The stamping head 18 (18 ') has a stamp 19 (19') which protrudes from the surface of the plate 23 of the gap Δ2, against which the pieces of timber to be stamped pass, e.g. by a cola conveyor. The device described above has two sets of stamping units 31A-34A, 31B-34B as well as two stamping openings 22A and 22B. There are four stamping units in each set, so by providing each stamping head 18 with a different stamping mark 19, a total of 24 different combinations of stamps containing two stamping marks are obtained, which is a sufficient number in many applications. A device with two sets of stamping units and one set of x different stamps and the second set of y different stamps yields x · y + x + y different stamp combinations. Three sets of units give the mentioned combinations x * y * z + x + y + z, respectively. The following are claims within the scope of which the various details of the invention may vary within the scope of the inventive idea. A stamping device for stamping pieces of timber or the like, in particular for identifying a sorter of timber pieces, the device comprising a plurality of stamping units, the stamps of which strike the pieces of wood or the like. the pieces of timber to be stamped are adapted to pass and in which the plate part (23) has at least two marking points (22A, 22B) spaced apart (Δ 2), e.g. a marking hole, and in which the device has a plurality of marking arms (13) articulated or correspondingly adapted to be rotatable by actuators (17) to provide a stamping movement, characterized in that the device has at least two sets of stamping units (31A-34A; 31B-34B), which sets stamp at different points (22A, 22B).
