The specific embodiment

In according to example scenario shown in Figure 1, in the incipient stage in operation of equipment cycle, by continuously longitudinally the stacking 1 that forms of the thin plate that obtains from timber section of plane be brought into the operation of equipment zone.At described embodiment, said thin plate is cut into slices from timber, and is dried and piles up with the order of section, and first up-to-standard thin plate is in the bottom.The diameter that depends on said timber is with forming a plurality of such stackings.The quantity of the thin plate sheet in a stacking is predetermined, and for example, 24, this depends on the application that equipment is used to carry out.A kind of method of cutting said thin plate sheet is that said thin plate sheet cutting is the heap layer, at first up to the interlude of said timber, afterwards, continues to form these heap layers through rotation timber at the back at interlude.

Thin plate utilizes the stacking apparatus production of traditional production stacking to obtain after being stacked in drying stage, and in the stacking that traditional stacking apparatus is produced, thin plate relative to each other is positioned at the top of other thin plate with quite random position.Said be stacked in the conveyer 2 that transports said stacking to operation of equipment zone above.

Said equipment comprises clamping limb 7,7 ', and each clamping limb all is connected to their actuator of reduction/lifting 3.The scope of the reduction/lifter motion of said clamping limb is set at the below that extends to stacking from the top of stacking.Said equipment also further comprises and clamping limb 7,7 ' bonded assembly actuator 6 and 6 ', and said actuator can make the clamping limb 7,7 ' that is positioned at the stacking opposite side in transversely operation in pairs of stacking, thereby can relative to each other push ahead respectively and draw back backward.Along with this motion, clamping limb 7,7 ' clamping element can be placed on the below of stacking and extract from the below of said stacking respectively.

Clamping limb 7,7 ' is supported by movable joint ground, and its angle of inclination can receive actuator 10,10 ' influence.

Clamping limb 7,7 ' actuator further comprise the device 5 that is used to make the arm oscillating traverse motion, such as having air pressure or hydraulically operated piston-cylinder unit.

For said hunting motion is provided, also can utilize crank device, make movement conduction to the said clamping limb that causes by eccentric mechanism as direct crank motion, perhaps selectively be to rotatablely move as off-centre.The advantage that selectable off-centre rotatablely moves is that it can stop said motion at the predetermined point of rotation, thereby stacking can be positioned at equipment with different indenting along the grain direction of thin plate.Therefore, single thin plate harness is opened so that the relation that vertically staggers is separated in the stacking that is formed by harness.

Said operation of equipment will describe with reference to accompanying drawing 2-5.

Shown in Figure 2 is the starting stage of said operation of equipment, and wherein conveyer 2 has been carried stacking 1 and come, and this stacking 1 is formed with the sequence stack of cutting into slices by the thin plate of drying.Depend on the structure and the operation of the equipment that piles up said stacking, thin plate relative to each other is positioned at the ccasual position along the thin plate plane in stacking.Clamping limb 7,7 ' has been fallen by actuator 3, thereby its clamping element is lower than the stacking of thin plate.In this step, the clamping limb that is positioned at the stacking opposite side is controllably driven by actuator 6,6 ' toward each other.Clamping limb 7, the 7 ' obliquity with upward opening are mounted, and slightly follow the section process of half wooden side view.

Their motion is toward each other up to the edge that touches the thin plate sheet that protrudes in stacking slightly, and this motion is by opto-electronic pickup 9, the 9 ' control at the edge of the opposite side of monitoring stacking.

After this was near motion, clamping limb will be in a way away from each other, and the thin plate stacking receives laterally back and forth vibrations and the hunting motion that utilizes actuator 5 to produce.Clamping limb moves towards each other, and keeps said shock motion, and monitoring is simultaneously influenced by the extruding that is caused by actuator 6,6 ' of said stacking.Therefore, just produce situation as shown in Figure 3, wherein, the thin plate above each other is aligned with each other.According to clamping limb 7,7 ' predetermined inclination, the part of the thin plate in stacking is arc.Pressure element 8 drops to the top of stacking, and arm 7,7 ' the clamping angle with respect to the stacking side can utilize actuator 10,10 ' to tighten up, and are used to improve the shaping (Fig. 4) of stacking, and after this, clamping limb 7,7 ' as illustrated in fig. 5 away from each other.

In an embodiment, suppose the said thin plate that comes from half wood with the sequence stack of section.Clamping limb 7,7 ' inclination mean the degree of dip of the side view of following said timber.The order of piling up also can be opposite, and this must consider to come in when the direction of tilt of adjustable clamp gripping arm.Yet the side view of following said timber is not necessary for said operation of equipment.Clamping limb also can be in vertical position; In this case, said equipment is applicable to handles the thin plate stacking of section from half wood, need not consider the order of piling up; Perhaps be applicable to processing and the section thin plate sheet stacking from whole timber, this depends on the application that equipment is used to carry out.

Make thin plate with its length direction, in other words, be arranged on the direction of texture that this also is possible in the stacking, the equipment of method that utilizes embodiment of the present invention is to the homogeneous end.Preferably, the upset of alignment timber.This can be through the said thin plate of adjustable support the clamping limb 7,7 ' of upset to realize operating on to low plane than the respective clamp arm on the top of supporting said thin plate.Therefore, the thin plate that is positioned at top of each other can slide along grain direction facing to the hill holder that is installed on the equipment in the upset of thin plate stacking during the initial period of vibrations.
