Description

This invention is a device for laying pads when rebuilding dense packages of sawn wood into drying bags (stacks) on pads with and without pliers for natural and artificial drying at sawmills and woodworking enterprises.

A device for laying gaskets when forming piles of boards is known, which includes a feeder with a pusher, a feed conveyor, a piece delivery mechanism for gaskets, and a distribution conveyor located on horizontal guides with stops on chains. However, well-known gas stackers have several cassettes, which makes them difficult to maintain and complicates reconfiguring when changing the laying position of gaskets on the bag and the width of the bag to be assembled.

In the proposed device, the horizontal guides are rotatably mounted, and the stops are made removable.

FIG. 1 shows a device for laying gaskets, side view; in fig. 2 - the same, top view; Fig. 3 shows a folding mechanism with tilting stops and a transient tongue mechanism; in fig. 4 — universal tapeless chain palletizer with rotary guides and portable stops; in fig. 5 is a diagram of the operation of the gasket stacker.

The laying stacker consists of a roller conveyor of dense packages 1, an inclined cable elevator .2, a frame of the device 3, a parsing mechanism and piece delivery of boards having an inclined multisection multi-speed conveyor 4, a screw leveling roller 5 and a piece delivery mechanism of boards 6. The stacker also includes leveling conveyor 7 with unequal chains, leveling role of action 8, a lay-up mechanism having a lay-up conveyor 9 with tilting lugs / O and a stepper conveyor 11 with a lamellar tape / 2, an emphasis / 5 and limit switches 14, 15, 16, a tongue mechanism 17 of a universal tapeless chain palletizer with rotary guides and portable stops, having a receiving part 18 with a movable wall 19, a folding conveyor 20, a pusher 21 and an overhead stop 22, a feed conveyor 25 and a piecewise dispensing mechanism 24, a distribution conveyor 25 with movable stops 26, swiveling guides 27, a shaft 28 with cams 29 and a vertical cable lift 30 of the unloading roller conveyor 3 one.

Dense lumber packages are delivered by motor vehicle trucks (forklifts, cranes with telpher or bridge tower cranes) and are placed on a roller conveyor of dense packages 1, which installs them over the pickups of a cable inclined lift 2.

The lift tilts the bag and lifts it up to the beginning of the sliding of the upper row of boards to the first section of the inclined conveyor 4 of the mechanism for parsing and single-piece dispensing of boards installed on the frame of the unit 3.

Boards, arriving in a pack on the first section of the inclined conveyor 4, are transferred to the second section, located below the first one and have a higher speed. When the boards move from the first section to the second, they are separated from the pack, i.e. "spread out into the carpet."

From the inclined conveyor, the boards are transmitted to a screw roller conveyor 5, where they are aligned with screw rollers on one end and fed to stops, the position of which is adjusted depending on the width of the boards. The reel, piece-by-piece mechanisms 6, vras, and together with the shaft, remove the extreme board from the screw roller table and drop it onto a chain to align it, conveyor 7. The board-release mechanisms and the leveling conveyor work simultaneously, ensuring that only one board is laid before with each abutment leveling his transporter -as: .e

The chain sections (between the stops) of this transorter 7 have different heights, and therefore the neighboring boards are transported at different heights. The boards lying on the low sections of the chains slide on the rollers of the leveling roller 8 and are aligned on the second end, and the boards lying on the high sections of the chains pass over the rollers and remain aligned on the first end.

The leveling board by the stops of the conveyor 7 is moved to the pick-up by the tilting stops 10 of the conveyor 5 of the folding mechanism operating synchronously with the leveling conveyor 7 from one drive.

Board, picked up by tilting supports 10, moves to the place of laying on the package. At the transition point of the board from the guide to the package, it moves along the tongue mechanism 17, which covers the ends of the laid gaskets from the side of the two boards and slides them onto the package gaskets.

The board moves along the gaskets until the tilting shank of the tilting stop 1Q passes the plate strip 12 of the stepping (wrapping) conveyor 14, which fixes the tilting stop in the working position.

on its axis, the shank presses the lever of the limit switch 14. A stepping (driving) conveyor drive is activated, which rotates the drive shaft through the overrunning clutch, and the lamellar tape 12 moves towards the boards by one turn equal to the width with the spine. The magnitude of the schaga is controlled by changing the angle of rotation of the drive shaft.

After the passage of the next stop with the plate of the plate, the tape again moves one step, and so on until a completely horizontal row (shield) of the boards is reached.

Before laying the last board into the shield, the stop 13 acts on the switch 16, and after laying this board from the limit switch 14 connected in series with the switch 16, the drive shaft coupling of the schagovy (dumping) conveyor turns on, the shaft receives rotation in the opposite direction, and the tape 12 begins to move in the opposite direction synchronously with the folding conveyor 9. At this time, the stepping movement drive is disconnected.

The movement of the lamellar tape takes place until the tape reaches the place where the first board is being laid.

The lamellar tape is stopped by switching off the coupling at the moment when the stop 13 acts on the switch 15. After that, another row (shield) of the boards can be laid.

Layer pads works as follows.

Gaskets with an unorganized pack are inserted into the receiving part 18, the ends of the gaskets are aligned along the side walls, the distance between which is adjusted depending on the length of the gaskets by moving the movable slug 19. The gaskets of the folding (leveling) conveyor 20 are selected from the pack. The upper gaskets, on the gaskets seized by the stops, roll down from the latter as they rise and are gripped by the following free stops. Gaskets that lie non-perpendicularly to the axis of the conveyor and do not roll down are discharged by the impact of the push rod 21. The second gasket is also reset if there are two gaskets between the lugs at the same time. The pusher 21 resets after the passage of each stop collapsible (leveling) conveyor. The pusher is raised by the cam.

The gaskets lying in front of the stops on the edge, when moving upward, meet the suspension stop 22 and fall downwards, since the installation height of the stop above the rails exceeds the thickness of the gasket, but is smaller than its width.

there is a formation of a dense shield pads. When the feed conveyor 23 is filled up, the collapsible (leveling) conveyor 20 is turned off. The conveyor 20 is automatically turned on after the predetermined length of the feeding conveyor is released from the gaskets.

When the distribution conveyor 25 is turned on, the movable stops 26, moving together with the chain, alternately press the limit switch, through which the command is issued to activate the mechanism for issuing the discharge 24, the shaft of which makes only one turn, since the further stop 26 moves limit switch and drive clutch off. The reel, rotating with the shaft, removes the outer gasket from the feeding conveyor 23 and passes it along the inclined guides to the pivoting guides 27 of the distribution conveyor 25.

After the next row (shield) of the boards is laid, a command is given for laying the gaskets. Shaft 28 makes one revolution, and its cams 29 alternately through rollers and levers turn back and forth swiveling rails 27. The pa package fits first one end of the gaskets, and then the others, which provides for more accurate laying and prevents them from being placed on edge.

After turning the guides 27 to the initial position, a command is issued to turn on the distribution conveyor 23.

When changing the width of the stackable package and the length of the gaskets to be laid, the retuning is performed by moving along the guides of the movable wall 19 in the receiving part 18, as well as by moving the rotary guide 27 mounted on special guides by clamping bushes. After the last row (shield) of the boards is laid on the package, laying of the gaskets is not performed.

At the end of the formation of the package (stack) of the set height, the vertical lift of the automatic slider goes down to the level of rolling out the package, a signal is given to the control panel and the forming mechanisms of the unit are turned off.

After the bag has been rolled out, the unloading roller conveyor 31 turns on a vertical lift.

An auto-lorry, crane or other lifting mechanism removes the ready-made packages from the bag forming unit. The formation of lumber can be carried out without transferring them to the drying tracks. In this case, a rail track is installed on the vertical lift, and on the installed

Direct tracks are formed on his tracks.

All mechanisms of the package forming unit are controlled from the operator control panel.

Operator Assistant lays gaskets and refills.
