Description

The invention provides a device for dosing unplasted sawn timber in continuous sawn timber processing in the wood industry without technological concentration for the purpose of storing and sorting into cages.

There is no known device for continuous processing of unplasted timber, ie. from its unification behind the frame saws to its processing for the production of various types of furniture blanks. The sawn timber is always concentrated at a certain geological site for manual sorting, cageing as required and transported by crane or forklift truck to various cage or baler disassembling systems prior to further technological processing.

These drawbacks in the processing of round timber are eliminated by a metering device according to the invention which transports unified and unedged sawn timber behind the frame or band saws horizontally in the transverse direction and consists of several transport sections connected to each other, which mechanically fold the arms overflow to cut-off saws. If the timber is not above the respective cross-cut saw, it is possible to return it by means of a conveying system and to the appropriate overflow.

The main effect of the timber dosing device in the transverse direction is that

2e, a continuous mode of lumber processing is achieved after unifying behind the frame and band saws in centrally controlled operations such as batching of the lumber to the cutters, purpose-class sorting of the lumber for storage, further processing and removal of the lumber in the bundle, resulting in savings production space, labor savings, 6 to 8 workers per shift in the technological node of lumber processing. The effect achieved is that, in theory, the possibility of injury compared to manual material handling is eliminated.

An example of the construction of the device according to the invention is shown in the attached drawing, where FIG. 1 shows a plan view of the whole apparatus and FIG. 2 is a side view of the device.

The device according to the invention is a cross-over conveyor with 6 conveyor chains consisting of a frame 1, four conveyor sections 2 with its own reversible drive 2 ^{and a} separate folding section of the arms 4 operated by pneumatic rollers

The illustrated sawn timber of width, thickness and thickness is fed by a beacon driven drive to the conveyor sections 2 with collapsible arms 4. From the control point a pulse is given over the respective pneumatic cylinders 5, which fold the arms 4 through which the timber is conveyed to the cutter. When the folding arms 4 are returned to the horizontal position, a smooth transition of the timber to the next conveying section 2 to the respective sorting point is ensured,

In case the sawn timber is not above the respective cross-cut saw or above the designated space, the sawn timber can be returned to the respective folding arms 4 by reversing the conveyor system. The device according to the invention can be used as a reloading cage by reloading the cage to one conveying section 2 and with a reduced conveying speed, it is moved to the other conveying section 2, whereby sawn timber appears one by one from the bottom of the cage when the arms 4 are lowered. Reverse feed discusses another series. This is done until the cage is finally disassembled.

Said device can be realized in all sawmills with frame and band saws irrespective of whether it is the processing of coniferous or leafy unplastered or plastered timber.

Claims (1)

214 348 2 that a continuous method of processing the sawn timber after the frame saws and the band saws is achieved in a centrally controlled operation such as dispensing the sawn timber to the sawing saws, purposefully sorting the sawn timber for processing and withdrawing the sawn timber. which results in savings in production space, labor savings, 6 to 8 workers per shift in the timber processing node, the salvage effect achieved, is theoretically eliminated by the possibility of injury versus material handling. An example of the construction of the device according to the invention is shown in the accompanying drawing, where Fig. 1 shows a plan view of the whole device and Fig. 2 shows a side view of the device. The device according to the invention is a transverse chain conveyor with 6 transport chains consisting of a frame 1, four conveying sections 2 with its own reversing mechanism 2 and a separate folding section of arms 4 controlled by pneumatic cylinders Expressed timber with a span, width and thickness it is fed to the conveying sections 2 with the straddle arms 4 by means of the propellant. The actuating point can be pulsed for the respective pneumatic cylinders 5 which fold the arms 4 through which the sawn timber is conveyed. When returning the stagger arms 4 to a horizontal position, a smooth transition of the rust to the next conveying section 2 to the respective sorting location is ensured. The device according to the invention can be used as a cage breaker with overlaps by placing the cage on one conveying section 2 and moving the conveying section 2 to the species with reduced transport speed, with the cage at the lowered arms 4 at the bottom. it looks lumber in one piece. Another shift is broken down by shifting. This is done until the final cage is disassembled. Said device can be realized in all sawmill plants with frame band saws, regardless of whether it is the processing of non-edged or beaded or plastered lumber. BRIEF DESCRIPTION OF THE INVENTION An apparatus for dispensing timber negotiated behind frame or band saws, handling timber horizontally in a transverse direction, characterized in that two or more conveyor sections (2) connected to each other by a frame (1) are provided, wherein each conveying section (2) has its own reversing drive (3) also serving to drive the sliding section (4) which provides the vertical movement with pneumatic or hydraulic cylinders (5). 1 drawing
