Description

The The invention relates to a device for conveying and packaging wooden blocks with the features specified in the preamble of claim 1.

Of the Application of such a device is in the field of optimization the quality of Wooden blocks, z. B. of boards and squared timbers. These become damaged Places such as B. branches or cracks with chop saws capped in Optimierungkappanlagen. The remaining thereafter, qualitatively good but shortened by capping pieces of wood in a finger-jointing plant back to a long pole, a long one Brett, a long squared timber or the like put together. To they are provided at their ends with a tine profile and with Glue put together. To achieve a rational way of working, the wood cuboid the finger jointing not individually, but fed as a package. The Package consists of several adjacent wooden blocks of same cross section, whose one end faces in a common flight aligned and together, in a single operation, with the Zinkenprofil be provided.

The present device for conveying and Packing serves to come from the chop saw, different long, good pieces of wood to put together to a package and to a conveyor to hand over, with the help of which they are fed to a Paketkeilzinkenanlage can.

The cuboid pieces of wood have typical lengths from about 150 mm to about 3,000 mm and cross sections of about 15 mm × 40 mm up to about 150 mm × 300 mm. Put together to a package become cuboidal Pieces of wood, that match in cross section, their length but can vary greatly. The device for conveying and packaging must be in the Be able to package for Wood cuboid with different cross sections, as stated above, perform.

The Wood cuboid, coming from the crosscut system, promoted on a feed conveyor, on which they are conveyed lying on their broad side transversely to their longitudinal extent. The feeder will therefore also as cross conveyor designated.

Of the Paketkeilzinkenanlage the timber cuboid but edgewise, so standing on its narrow side, assembled in a package in the longitudinal direction fed to the wood cube. The wooden cuboids are therefore so to a transversely to the feed conveyor discharge conveyor to hand over, that they are on the conveyor stand upright and always several of them alongside each other to one Package to be put together.

The from a device for conveying and packing wooden blocks demanded work performance depending on the performance of the cross-cut system or after the work the Paketkeilzinkenanlage, with which the device for conveying and Packing wood blocks must work together. At the current state The technique requires a device for conveying and packaging of wooden blocks a performance of up to 100 wooden blocks per minute. Known devices are unable to do so, which is why Packaging is usually done by hand. typically, three people are needed with a feeder to take off transported wooden blocks from the feeder, upright along side by side on a conveyor to put them together in a package and preferably also to be aligned with one end in one lying together.

Through use of known is a device whose principle of operation schematically in 7 is shown.

7 shows a trained as a horizontal conveyor feeder 101 , on whose upper strand wood cuboid 102 be encouraged across. At the end of the feeder is a swivel arm 103 provided, which about a horizontal axis 104 is pivotable, whose position coincides with the axis of rotation of pulleys 105 a second horizontal conveyor 106 , which is designed as a chain conveyor, that is, it has a plurality of spaced juxtaposed endless chains, which are stretched over pulleys, one of which is driven in each case.

By swinging up the swivel arm 103 every wood block comes 102 upright on the upper run of the horizontal conveyor 106 , A counterholder 107 secures the wood cuboid 102 pointing at the horizontal conveyor 106 were swung up, against falling over. The counterpart 107 is on the chains of the horizontal conveyor 106 attached and is moved with these to on the horizontal conveyor 106 Make room for the next wood block 102 , Has the package of wood squares 10 reaches the desired size, it is carried away. Since the packages are carried away in the longitudinal direction of the wood cuboid, is in the horizontal conveyor 106 a roller conveyor 108 integrated, whose axes of rotation 109 in the conveying direction of the horizontal conveyor 106 run. The roller conveyor 108 lies in the packaging under the upper strand of the chains of the horizontal conveyor 106 , To convey the package is the roller conveyor 108 if raised or the horizontal conveyor lowered so far that the rollers on the upper run of the horizontal conveyor 106 protrude so that the roller conveyor 108 the package from the wooden blocks 102 from the chains of the horizontal conveyor 106 lifts and by driving the rollers transverse to the conveying direction of the horizontal conveyor 106 transported to the finger jointing plant.

A disadvantage of the known device is that with the reciprocating arm 104 not more than 40 wood blocks per minute can be implemented. Another disadvantage is that roller conveyors are unfavorable for the conveyance of short wooden blocks because they can tip into the gaps between two adjacent rollers, sometimes with their front end forward, sometimes with their rear end to the rear.

The principle of operation of another known device for conveying and packaging wooden blocks is shown schematically in FIG 8th shown. A feeder designed as a horizontal conveyor 111 promotes the different lengths of wood cuboid coming from a crossbeam 112 lying across on its broadside. At the end of the horizontal conveyor 111 is at a lower level a discharge 113 provided, which is also a horizontal conveyor, but one transverse to the conveying direction of the feed conveyor 111 has a running conveying direction. The cuboid pieces of wood 112 fall at the end of the horizontal conveyor 111 via a drop level on the discharge conveyor 113 , For this purpose is through the end of the feeder 111 and a vertical guide means spaced therefrom 114 a chute limited. Under the feeder 111 is a cross slide 115 provided, which consists of a in 2 shown retracted position in one above the discharge conveyor 113 lying position can be advanced, in which he with the guide device 114 Aligned, which of the upper strand of the conveyor 113 so much distance has that the wood cuboid 112 Standing upright under the guide device 114 can be pushed through.

The known machine is clocked so that the wood cuboid from the feed conveyor 111 fall off when the cross slide 115 is in its advanced position. The cross slide 115 is then withdrawn so that the wood cuboid fallen on him 112 continues down to the discharge conveyor 113 , At the next feed of the cross slide 115 becomes the wood cuboid 112 under the leadership facility 114 pushed through against a pneumatically receding anvil 116 which the falling of the wood cuboid 112 prevent and allow the formation of packages. Given the cross-sectional dimensions of the wood cubes up to 150 mm × 300 mm, the fall path of the wood cuboid is at least 300 mm. This has the consequence that in particular shorter and smaller in cross-section wood cubes tend to jump uncontrollably and break out to the side. This results in disturbances in the operation of the known device, so that despite a possible rapid movement of the cross slide 115 The performance of the machine is much smaller than would theoretically be possible if the wood cuboid would not jump and break out. Another disadvantage of the known device is that the cross slide has to apply relatively large forces in order to move the package already in formation by overcoming the pneumatic counterforce of the counter-holder transversely. The result of this is that the packages tend to collapse more or less when there are one or more short wooden blocks between two longer wooden blocks. In addition, it is disadvantageous that always the entire package already formed must be moved so that the required thrust from time to time is greater.

Of the present invention is based on the object, a device of the type mentioned above to improve that both fast as well as reliable packetized.

These Task is solved by a device having the features specified in claim 1. Advantageous developments of the invention are the subject of the dependent claims.

The inventive device has a feeder, on which the wooden cuboid on its broadside lying across to their longitudinal extent promoted be and a pickup, which is arranged lower than the feeder and on which the wood cuboid edgewise lying on its narrow side and put together in packages in their longitudinal direction transverse to the conveying direction of the feeder carried away become. For the passing the wood cuboid from the feeder on the conveyor is a transfer facility provided, which conveyed lying on its broadside Erecting wooden cuboid and transferring it upright to the discharge conveyor.

In departure from the known prior art, the invention provides that the discharge conveyor transversely to itself, ie in the conveying direction of the feed conveyor, is displaceable. This has the advantage that the wood blocks are parked by the transfer device on the discharge conveyor from the outset in a place that they occupy in the stack to be formed. The discharge conveyor is therefore moved during the formation of a stack of wood squares transversely to himself in such a way that each wood cube is placed next to the previously parked wood cuboid, the discharge so from parking a wooden cube until the next wood cuboid by the thickness of the wood cube is moved further, preferably synchronously with the drive of the transfer device. The cross Movement may be in cycles, but is preferably done as a smooth, continuous motion. A preferably provided slide is only used to close a possible gap between the two last parked cuboids. For this he has to move only the last wood cube slightly. The required effort is low and does not increase with increasing package.

To the Support of the first parked on the conveyor Holzquaders is provided on this preferably a counter-holder, which is at the, the transfer device remote edge of the discharge conveyor located and preferably provided with a safety shutdown is. This counter-holder is preferably cushioned to the movement if necessary, to be able to avoid the slide. Of the Suspension travel for that made available can be, can be low. Preferably, the counter-holder is through one or two pneumatic short-stroke cylinders cushioned.

In a particularly advantageous embodiment of the invention has the transfer device one the feeder continuing, downwards curved Trajectory and synchronous with the feeder drivable supports, which are along the curved Trajectory downhill move and on which the wood cuboid during the downward movement lie with one of their narrow sides. In addition, the transfer device a supporting device arranged at an angle to the supports on which the wood cubes rest and are supported, when they are on the supports along the curved trajectory move down to the conveyor.

• • Die Holzquader gelangen nicht im freien Fall auf den Abförderer, sondern kontrolliert mit einer Geschwindigkeit, die von den Auflagern vorgegeben ist.
• • Während sich die Holzquader mit kontrollierter Geschwindigkeit an der gekrümmten Bewegungsbahn entlangbewegen, werden sie allmählich aufgerichtet. Auch dieser Vorgang erfolgt nicht abrupt, sondern kontrolliert.
• • Sowohl der Aufrichtvorgang als auch der Absenkvorgang erfolgen fließend und schonend.
• • Ein Hüpfen, Springen, seitliches Ausbrechen, Hochstellen und Umfallen der Holzquader sind ausgeschlossen. Unerwünschte Betriebsunterbrechungen durch solche Fehler sind deshalb ebenfalls ausgeschlossen.
• • Die Vorrichtung arbeitet für alle möglichen Formate der Holzquader gleich gut, für kurze wie für lange Quader, für im Querschnitt rechteckige, wie im Querschnitt quadratische Quader, für Bretter ebenso wie für Kanthölzer.
• • Die kontrollierte, kombinierte Aufricht- und Abwärtsbewegung kann synchron mit der Bewegung des Zuförderers problemlos in der gewünschten Geschwindigkeit erfolgen, so dass das bisher überwiegend manuell vorgenommene Aufrichten und Paketieren der Holzquader nunmehr zuverlässig vollautomatisch erfolgen kann. Dadurch wird zugleich die Arbeitssicherheit erhöht.

This has significant advantages:

• • The wood blocks do not reach the outfeed conveyor in free fall, but controlled at a speed specified by the supports.
• • As the wood cubes move along the curved trajectory at a controlled speed, they are gradually raised. This process is not abrupt, but controlled.
• • Both the erection process and the lowering process are smooth and gentle.
• • Bouncing, jumping, sideways breaking, raising and falling over of the wood blocks are excluded. Unwanted business interruptions due to such errors are therefore also excluded.
• • The device works equally well for all sorts of wood cubes, for both short and long cuboids, for rectangular in cross-section, as in the square cross-section cuboid, for boards as well as squared timbers.
• • The controlled, combined up and down movement can be carried out synchronously with the movement of the feed conveyor at the desired speed without any problems, so that the predominantly manual erection and packing of the wood blocks can now be reliably fully automatic. As a result, at the same time the safety at work is increased.

Of the feeder and the conveyor are expediently Horizontal conveyor. The discharge conveyor preferably has an endless conveyor link in the form of a conveyor belt, which is especially good for it suitable to merge several wooden cubes to a package and this then in the longitudinal direction to remove the wood block. The feeder could also with an endless conveyor belt work, but preferably several at a distance parallel to each other continuous endless conveyor links, which are bands can act. Preferably, however, they are conveyor chains or belts, in particular toothed belts, with which a slip-free Transport is guaranteed. This is important so that the wood cubes align their orientation at right angles to the conveying direction on the feeder maintained.

The Supports on which the wooden cuboid moves in a controlled manner downwards can, can at the conveyor links of the feeder be provided. In this case you would get the funding links of the feeder at the end, which is the discharge conveyor is adjacent, about such a big one Radius redirect that at the intended conveying speed upright the wood cube does not take place too quickly, reflecting the location of the wood cube could destabilize. Besides that is It is recommended to use the wood cubes to attach to the supports before moving down at the end of the feeder.

Preferably the device is designed so that the supports while synchronous with the feeder, but separated from the conveyor links of the feeder who moves the. For this purpose, the transfer device preferably a separate transfer conveyor, which a plurality of spaced apart parallel conveyor elements having overlapping with the feeder, by conveying links of the transfer conveyor in interspaces between the conveyor links of the feeder protrude and vice versa, where it matters that this each for the Upper strand of the conveyor links true.

The feed conveyor is preferably drivable faster than the transfer conveyor with its supports. This has the advantage that the wood cubes promoted in the overlap region of the feed conveyor and the transfer conveyor forcibly from the faster feed conveyor to the slower support who the. This ensures that the wood cubes are already at their supports when they begin to move down.

The Slow down the different speeds of the feed conveyor and the transfer conveyor the device as a whole, but merely result in that the wood cuboid on the feeder lie in greater distances as on the transfer conveyor, as far as they are not on the feeder jammed at a stop and then isolated and handed over to the transfer conveyor be sure to always have only one on its supports only wooden block is located.

The transfer conveyor has as endless conveyor links preferably chains or timing belts, both a slip-free Enable transport. The Supports can Cams attached to chain links or the timing belt molded, vulcanized or riveted. Especially when using of chains as conveying links the favorable results Possibility, at the conveyor links Claws to be used as an abutment, which is that they themselves dig a little into the wood cube, this one especially good Stop.

Between the feeder and the conveyor is preferably a parallel to the upper strand of the discharge conveyor provided back and forth movable slide. He is part of the transfer facility and serves the wood cuboid, which is about the curved trajectory down moved and parked on the conveyor have been moved individually on this to move them individually successively to the plant at the previously parked on the discharge conveyor Wood cuboid can be brought.

Preferably the pusher is comb-like and has tines in the interspaces between the conveyor links of the transfer conveyor intervention. This has the advantage that the slider no hindrance is, the transfer conveyor so to arrange that the supports are only on the top strand of the conveyor or just above the upper run of the discharge conveyor from the wood squares to solve, so that they are placed gently on the upper run of the discharge conveyor.

Of the Slider is preferably driven by a crank. That has the advantage that he does not in his reversal points (dead center) strikes hard but by the crank characteristic to zero speed is braked without requiring braking or damping devices would. The crank drive optimally accelerates the wood blocks and delayed. Another advantage is that the slide by a Motor with rotating drive shaft can be driven steadily. Preferably, the engine is the same engine, which also drives the transfer conveyor and preferably also the device for separating the jammed Wooden cuboid, so that the movement of the slide forcibly mechanical with the movement of the transfer conveyor and preferably also with the device for separating the wood cuboid is coupled. For synchronizing these three components of the device therefore no control effort required.

1 shows a feeder 1 formed as a horizontal conveyor with a plurality of mutually parallel endless conveyor links, which via deflecting wheels 14 are curious, of which a group is driven. The conveyor links may be chains or belts, in particular toothed belts.

A transfer conveyor 2 also has a number of endless conveyor links, which are arranged at a distance parallel to each other and around diverting wheels 15 and 16 are curious of which the pulleys 15 are driven. At the conveyor links of the transfer conveyor 2 they may also be chains or belts, in particular toothed belts. The transfer conveyor 2 and the feeder 1 are arranged overlapping each other by conveying members of the transfer conveyor 2 in intervals of the conveyor links of the feed conveyor 1 lie and vice versa.

At the conveyor links of the transfer conveyor 2 are regular supports 3 , z. B. cams arranged.

Below the feeder 1 is a conveyor 10 arranged, which is designed as a horizontal conveyor and has a conveying direction which is perpendicular to the conveying direction of the feed conveyor 1 and the transfer conveyor 2 runs. The discharge conveyor 10 is transversely displaceable on a reciprocating drivable shifting device 13 stored, which parallel to the conveying direction of the feed conveyor 1 is shiftable back and forth.

The discharge conveyor 10 has a wide conveyor belt, which is stretched over two guide rollers, one of which is driven. At that edge of the conveyor belt of the discharge conveyor 10 , which is the greater distance from the feeder 1 has, is in the conveying direction of the conveyor 10 extending counterholder 11 arranged, which by one or more pneumatic Kurzhubzylinder 12 is cushioned.

Above the discharge conveyor 10 is at a distance from the end of the transfer conveyor 2 a vertical guide device 17 intended. The distance of the guide device 17 from the end of the transfer conveyor 2 is chosen so that cuboid pieces of wood 18 having the largest thickness occurring through the gap between the guide means 17 and the end of the transfer conveyor 2 fit through.

A slider 6 , which in the conveying direction of the feed conveyor 1 is drivable back and forth between the transfer conveyor 2 and the conveyor 10 arranged, with at most a small distance to the upper run of the discharge conveyor 10 , The slider 6 is comb-like and has tines, which in the space between the conveyor members of the transfer conveyor 2 intervene, leaving the slider 6 and the conveyor members of the transfer conveyor 2 overlap each other. The slider 6 is by means of a crank mechanism 8th driven. The drive is made by a motor 7 , which not only the crank mechanism 8th drives, but also the transfer conveyor 2 so that they are forcibly synchronized with each other.

The conveyor links of the transfer conveyor 2 run in the overlap area with the feed conveyor 1 and still a bit beyond horizontally and then describe a bent over an angle of 90 ° down trajectory with a relatively large radius of curvature, for example, 30 cm to 60 cm. The lowest point of the conveyor links is located at the pulleys 16 that have a small radius (ie compared with the radius of curvature of the trajectory) small radius. From the pulleys 16 the lower run of the conveyor links of the transfer conveyor rises 2 on to the driven pulleys 15 ,

The device works as follows:
At the beginning of a packaging process is the discharge conveyor 10 on the displacement device 13 in its one end position, in which the guide device 17 over the counterpart 11 stands, as in 2 shown. wooden block 18 be from the feeder 1 promoted, which moves faster than the transfer conveyor 2 , This will get the wood cuboid 18 in the overlapping area of the feeder 1 and the transfer conveyor 2 in any case for attachment to a number of supports 3 , Such a wood cube 18 will be at the camps 3 and the conveyor links down along the curved trajectory down and thereby gradually erected. If the supports 3 in the area of the front pulley 16 they are redirected, causing the wood cube 18 from the support 3 dissolves and in the gap between the supports 3 and the guide device 17 the last short pieces except for the upper run of the conveyor 10 slides down, see 1 , The first wood block 18 a parcel lands in the position that is in 2 is shown, close to the anvil 11 on which he passes through the gate 6 subsequently brought to the plant.

Until the next wood block 18 in the same way on the conveyor 10 passes, this is through the displacement device 13 about the thickness of a wood cube 18 in the sense of the 1 moved to the right, leaving the second wood block 18 close to the first wooden block 18 on the conveyor 10 is discontinued. In this way, a packet is gradually formed, see 1 until finally the discharger 10 over almost its entire width with wooden blocks 18 is filled, as in 3 shown. In this condition, this is made of the wood squares 18 formed package and the empty discharge conveyor 10 in its initial position, 2 , moved back.

The in the 1 to 3 shown essential elements of the device according to the invention are also in the in the 4 to 6 illustrated embodiment include:
The device has a frame 19 which is the feed conveyor 1 , the transfer conveyor 2 and the conveyor 10 wearing. The feeder 1 has as endless conveyor links 20 a plurality of parallel spaced apart juxtaposed chains, which via gears 14 and 21 are strained and deflected, of which the gears 14 by a motor 22 are driven.

The transfer conveyor 2 also has several parallel juxtaposed endless conveyor links 23 in the form of chains, which over gears 15 and 16 are curious, of which the location of the gears 16 hidden and therefore shown only by dashed lines. The group of gears 15 is through a chain 24 powered, which in turn by a chain 25 from an electric motor 26 is driven.

The curved trajectory 27 of the transfer conveyor 2 is through curved vanes 28 given on which the chains 23 slide. At the chains 23 are regular supports 3 provided in the form of claws, to which the wood cubes to be packaged 18 get to the plant.

The between the transfer conveyor 2 and the conveyor 10 provided slide 6 is by means of a crank mechanism 8th with crank 29 and connecting rod 30 through the electric motor 26 driven so that the movements of the transfer conveyor 2 and the slider 6 are mechanically synchronized. The crank 29 is as a disk with holes 29a formed, which have different distances from the crank axis. At one of the holes 29a is the connecting rod 30 attached, whose stroke from the distance of the selected hole 29 depends on the crank axle. Which deals with the transfer conveyor 2 overlapping tines of the slider 6 have heads 31 on the top of the conveyor 10 escort.

The discharge conveyor 10 has as an endless conveyor link 32 a wide conveyor belt, which has two guide rollers 33 and 34 is curious, of which the guide roller 33 from an electric motor 35 by means of a chain 36 is driven.

The discharge conveyor 10 is on two rails 37 stored, which on the frame 19 are attached and in the conveying direction of the feed conveyor 1 close to the crank 29 extend. On these rails 37 is the discharger 10 displaceable transversely to its conveying direction. For this purpose is a chain 38 provided, which via gears 39 and 40 is curious, of which the gear 40 by a motor 41 is drivable. The ends of the chain 38 are on a sled 42 attached, which on the rails 37 slides and the discharge conveyor 10 wearing.

On the rails 37 and on other tracks lying in their flight 45 are also the feeders 1 and the associated transfer conveyor 2 stored. The rails 37 and 45 allow the position of the feeder 1 and the transfer conveyor 2 in their direction of conveyance for adaptation purposes. That's why the gear is 15 , which are the conveyor links 20 of the feeder 2 does not drive a short way from the electric motor 26 powered, but over the low gear 44 and the long chain 24 , The rails 37 also wear the slider 6 ,

As in the example of 1 to 3 is the feeder 1 faster drivable than the transfer conveyor 2 , So that from the feeder 1 brought wood block 18 matching the grid in which the supports 3 are provided to the transfer conveyor 2 to be handed over is between the sponsoring members 20 of the feeder 1 a series of attacks 46 provided, on which the wood cuboid 18 First of all stopped and dammed up. lift cam 47 that between the attacks 46 are arranged, are synchronous with the transfer conveyor 2 drivable. For this purpose drives a chain 48 , which from the engine 26 over the chains 25 and 24 is driven, a gear 49 , which by means of an eccentric the lifting cams 47 in one with the drive of the transfer conveyor 2 synchronized clock raises. This will be the immediate next to the attacks 46 lying wooden cuboid 18 from the conveyor members 20 of the feeder 1 individually lifted and over the stops 46 raised. He comes in contact with rubber wheels 50 which - preferably uninterruptedly - by a motor 51 are driven. The rubber wheels 50 carry the wood cuboid 18 about the attacks 46 time. In this way, the wood cubes are individually and in time to the gear 15 emerging support 3 to the transfer conveyor 2 to hand over. This ensures that on the supports 3 in each case only a single wood block 18 comes to the plant, even if the feeder 1 constantly running and the transfer conveyor 2 temporarily shut down, z. B. while a package of wooden blocks 18 from the conveyor 10 carried away, see 3 , and the forwarder 10 into its starting position, see 2 , is moved back.

wooden block 18 By lifting over the stops 46 be singulated and then individually to plant on supports 3 of the transfer conveyor 2 get along the downward curved trajectory 27 on the conveyor belt 32 of the conveyor 10 discontinued. A falling over of the wood cuboid 18 This prevents the wooden blocks 18 between the slider 6 and one to the transfer conveyor 2 opposite guide device 17 land, which z. B. may consist of two mutually parallel bars, rails or flat iron, which are at a distance from each other. The management device 17 is at a traverse 52 of the frame 19 suspended and can be adapted to different height wood cubes 18 be adjusted in height so that the wood cuboid 18 standing upright on the discharge conveyor 10 were turned off, by means of the slider 6 under the leadership facility 17 can be pushed through.

So that the wood cuboid 18 not by the Gap between the guide device 17 and the conveyor belt 32 of the conveyor 10 through is near the lower edge of the guide means 17 a latch 53 provided, which about a horizontal axis 54 from her in 4 drawn position in which it depends vertically down, can be swung up in an inclined position when the slide 6 a wood block 18 against the latch 53 pushes. The axis 54 is located on a lever 55 , which is on a sledge 56 is articulated, which height adjustable on the crossbar 52 attached and also the management device 17 wearing. The axis about which the lever 55 is pivotable with is 57 designated.

Becomes a wood cuboid 18 through the slider 6 against the latch 53 pushed, then this is pivoted in a fixed predetermined angle. About the inclined surface, which the pawl to be moved wood cuboid 18 the latch and with it the lever becomes 55 on which it is located, by pivoting the lever 55 and its axis 57 raised until the wood cube 18 the handle 53 happened. Then fall the latch 53 and the lever 55 back to their starting position. The initial position of the lever 55 is thereby ensured that the lever 55 through a chain 58 with the sledge 56 connected is. The initial position of the lever 55 is - as in 4 shown - horizontal.

Should be a wood cube 18 between the transfer conveyor 2 and the guide device 17 and / or the latch 53 wedging, then the sled can 56 against a pneumatic spring 59 flinch. The pneumatic spring 59 is coupled to a switch, which then shuts off the drive of the machine for safety.

Has the on the conveyor 10 formed stack of wooden blocks 18 reaches a predetermined width, the transfer conveyor 2 temporarily shut down and the pile of wood squares 18 by driving the conveyor belt 32 conveyed away. Thereafter, the discharge conveyor 10 by driving the chain 38 moved back in its initial position, in which the counter-holder 11 in the immediate vicinity of the management facility 17 located.

If the feeder 1 the transfer conveyor 2 steady with wooden blocks 18 Charged, the engine can 41 , which is the transverse displacement of the discharge conveyor 10 causes to be controlled so that it can move steadily until the intended stack width is reached.

4 shows the device in a phase in which a package 43 made of wooden blocks 18 on the conveyor 10 is almost complete.
