Description

TECHNICAL FIELD The present invention relates to a wood barker carry-in device and a carry-in method. More specifically, the present invention relates to a device and a method for loading timber with a wire collapse preventing wire loaded on a truck onto a chain conveyor with the wire attached, removing the wire, and then carrying the wire into a barker.

[Prior Art] Conventionally, wood transported by a truck is temporarily unloaded on a soil site, loaded and stored, and then a log loader or a forklift truck is used to convey a barker, for example, a belt conveyor or a chain conveyor. Or it is transferred onto a cable conveyor. In addition, it may be directly loaded into the barker by a log loader or the like.

However, in the conventional method, since the wood is once lowered to the soil, a place for unloading the wood and a temporary storage place for the stock are required. Further, it is necessary to have a log loader or the like to transfer to a carry-in conveyor, a passage therefor, and a work place. In addition, it is necessary to unload the transported timber to the ground and remove the wire collapse prevention wire. Further, depending on the operation rate of the log loader or the like, the amount of wood that is put into the barker may vary, and the barker operation efficiency may be reduced.

[Problems to be Solved by the Invention] The present invention prevents an increase in the soil area by temporarily unloading wood to the soil, eliminates the need for transportation costs from the soil to the barker, and allows the wood to be delivered to the barker. An object of the present invention is to provide a wood carrying-in device and a carrying-in method capable of improving the operation rate of barkers by uniformly feeding.

[Means for Solving the Problems] A wood carrying-in device of the present invention comprises a slantable track damper, a live deck disposed at a slanted lower end portion of the track damper and slanted upward in the wood transporting direction, and the live performance. At least two rows of chain conveyors in which the deck is divided into at least two groups by drive means and continuous in the wood conveying direction, and means for making the deck movable between upstream and downstream in the wood conveying direction are provided between the frame conveyors. An apparatus for carrying in a barker of wood, comprising: at least one attachment having the attachment; and the attachment having at least one timber collapse preventing column fitting inlet on the upstream side of the attachment in the wood conveying direction.

In the method for carrying in a wood barker of the present invention, the wood loaded with the wood collapse prevention wire loaded on the truck is divided into at least two groups by the driving means by the tilt of the truck damper, and tilts upward in the wood transport direction. Dropped on the chain conveyor, the operation of the chain conveyor to move the wood on the chain conveyor grouped downstream in the wood transport direction, remove the wire on the group of chain conveyors downstream in the transport direction, By operating the chain conveyor, the wood was dropped to the hopper for carrying in the barker, but when removing the wire of the wood on the chain conveyor of the downstream side group, the wire was hooked on the chain conveyor of the group upstream of the group. Wood loaded with wood, or wood hung or unwired A Barker carrying method of the wood, characterized in that the advance upstream by fitting the strut to the inlet fitting strut for timber collapse prevention of attachment can be moved up and down stream side among the chain conveyor frame.

The track damper is composed of a board base whose one end is movably held by shaft attachment, etc., a transmission means such as a hydraulic cylinder or an elevated hoist for lifting the board base to the other end of the board base, and the board base. The lower end of the slope is equipped with a stopper for preventing the track from slipping. Means for preventing tracks from slipping, such as a chain, may be installed at the upper end of the slope of the board. The material of the board is not particularly limited as long as it has a strength capable of withstanding the weight of a truck loaded with wood such as an iron plate.

A live deck tilted upward in the wood transport direction will be installed at the lower end of the track damper. The live deck may be installed near horizontal in some cases. In the live deck, at least two rows of chain conveyors, preferably two rows of chain conveyors, are divided into at least two groups, preferably three or more groups, by driving means, and are installed at both end portions of the live deck. A chain conveyor may be installed in the center. The chain conveyor is endlessly rotated by a drive motor for each group. It is preferable that the chain conveyors are continuously installed in the wood conveying direction, and that a wood swinging part by a chain conveyor stand is provided between the successive chain conveyors so that the wood slides thereon. The number of groups can be arbitrarily set in consideration of the peeling ability of the barker, variations in the time when the wood is brought in by the truck, and the like.

Two chain conveyors are installed on each side of the live deck.
You may install in rows. Also, any chain such as a single chain or a double chain can be selected. Keys may be provided on the chain to prevent slipping of the wood. The length of each grouped chain conveyor on the wood transport side is preferably such that one truck's worth of wood can be loaded. When dropped, the wire that bundles the timber loosens to prevent the collapse of timber when the truck is loaded, and the length of the wire is about 6 to 7 m on the live deck. Therefore, the length is preferably 6 to 7 m. It is preferable that the length between the chain conveyors installed at both ends of the live deck is slightly shorter than the length of the wood to be conveyed.
The length of the live deck, the angle of inclination, and the transport speed can be arbitrarily set in consideration of the peeling ability of the barker, variations in arrival times of trucks loaded with wood, and the like.

Between the racks of the chain conveyor, recesses formed by the racks and pedestals of the chain conveyor are provided, and the attachments, which are movable upstream and downstream in the wood transport direction, are installed on the recesses. The attachment may be moved by fixing a pulling means such as a wire or a link to the attachment and moving the attachment or the like. Further, a driving means may be installed on the attachment itself and the attachment may be moved by the driving means. In this case, it is preferable to install a rack gear in the recess and the attachment to prevent the attachment from moving backward. If the live deck is close to horizontal, the attachment does not have to be installed.

On the upstream side of the attachment in the wood conveying direction, at least one fitting opening into which the wood collapse preventing pillar can be fitted is provided. When the chain conveyor is installed only at both ends of the live deck, only one attachment may be installed, and in this case, it is preferable that two fitting inlets are provided at both ends of the attachment. The fitting port may be provided on the attachment itself, or a member having the fitting port may be provided on the upstream side of the attachment in the wood conveying direction. As the support columns, any of logs, square members, iron rods, and the like can be used as long as they have a strength capable of preventing the load collapse of wood. In order to prevent the attachment from obstructing the movement of the attachment due to the bark peeled off from the wood, it is preferable to form the front part of the attachment in the wood transport direction into a single-edged shape. Further, in order to make the movement of the attachment smooth, it is preferable to install wheels or the like on the attachment.

A hopper for receiving the wood dropped from the live deck is installed on the downstream side of the live deck in the wood conveying direction, and the wood is supplied to the barker via the hopper.

[Operation] After the truck loaded with the timber tied with wires is stopped on the board, the board is tilted and the wood on the truck is dropped on the chain conveyor with the wire attached. Then, the chain conveyor is operated to convey the wood.
When the wood reaches the grouped chain conveyor on the most downstream side in the wood conveying direction, or before that, the wire that bundles the wood is removed. Since the wood is supported by the chain conveyor and there is no contact with the part where the wires are bundled, it is extremely easy to remove the wires.

When removing the wire, if there is no subsequent timber on which the wire is hooked, the attachment is moved to the upstream side in the conveying direction of the timber from which the wire is removed, and the pillar is fitted into the pillar fitting port to prevent the wood from slipping off.

Since the chain conveyor can be operated for each group,
The wood dropped from the truck can be successively moved onto the chain conveyor of the upstream group of the wood dropped first. For this reason, timber can always be loaded on the chain conveyors in the downstream group in the timber conveying direction, preventing discontinuity of timber input into the barker and wood input due to variations in truck arrival time. can do. In addition, by setting the operation switch of each chain conveyor group near the truck damper,
The truck driver can also operate the truck damper and the chain conveyor of each group, which is also effective in saving labor cost.
