Description

DETAILED DESCRIPTION OF THE INVENTION The present invention appropriately feeds wood into a sawmill, automatically moves the wood to a position above the center of the sawmill's sawmill, and places the center of the wood on the sawmill's sawmill. This invention relates to a device for setting the center position of a piece of wood that accurately matches the center chuck.

Traditionally, the wood that has been transferred onto the transport vehicle of the lumber machine by a chain life deck or by an appropriate method is manually adjusted so that the center of the timber matches the center of the transport vehicle. However, since the lumber is not easily attached to the lumber transport vehicle, there are disadvantages such as dangerous inspections and inefficiency.

The present invention has been devised in view of the above-mentioned deficiencies in the setting of timber for this type of conventional lumber transport vehicle.

An example of the implementation of the present invention will be described in detail with reference to the drawings.The present invention will be described in detail with reference to the drawings. hand,
A first fixing machine frame 5 and a second fixing machine frame 6, which can have an upper surface 4 at a higher level than the material transport vehicle 3, are provided facing each other.

A first support shaft 8 and a second support shaft 9 are horizontally parallel to the rail 2 on the upper surfaces of the opposing inner sides 7 and 7 of the first fixed machine frame 5 and the second fixed machine frame 6, respectively. The base ends 11 of the first receive arms 10, 10 are mounted near both ends of the first support shaft 8.

The stopper arm 48 is raised and lowered by the extension and contraction operation of the piston rod 51, and each time the stopper arm 48 is raised and lowered, the wood a that has reached the tip of the chain live deck 45 is transferred onto the liep roller 20 one by one. There is.

Note that the reference numeral 52 in the drawings is a band saw placed in a fixed position.

Next, the operation of the present invention will be explained in detail with reference to the drawings.
The piston rods 16 and 19 of the working cylinders 15 and 18 are retracted to separate the first receiving arm 10 and the second receiving arm 12 into a hanging state, and the working cylinder 23
The piston rod 24 of the actuating cylinder 43 is retracted to incline the flipper 21 to a lower position than the upper peripheral surface of the lie roller 20, and the piston rod 44 of the actuating cylinder 43 is retracted to move the movable plate 40 to an upward position. The first movable positioning plate 29 and the second movable positioning plate 30, which are connected to the elevating movable plate 40 via a chain 41, are retracted and placed in a separated state, and the piston rod 51 of the operating cylinder 50 is retracted. Then, the stopper arm 48 is erected, and with the stopper arm 48 locking the wood a transferred to the tip of the chain live deck 45, the piston rod 51 of the operating cylinder 50 is first extended, and the stopper arm When the lumber 48 is inverted, the unlocked wood a is transferred onto the liep roller 20.

The wood a placed on the liep roller 20 is adjusted slightly back and forth as necessary, and then the piston rods 16, 19 of the actuating cylinders 15, 18 are extended, and the first receiving arm 10 and the second receiving arm are moved. 12 are actuated in a downwardly inclined manner so as to face each other inwardly, and their tips intersect with each other in a staggered manner to form a V-shaped receiving part, and then the piston rod 24 of the actuating cylinder 23 is actuated to extend, thereby ripping the flipper 21. A piece of wood a placed on a flipper 21 which is tilted upward from the upper peripheral surface of the roller 20 is formed by intersecting the tips of the receiving arms 10 and 12 from above the flipper 21. Transfer it to the receiving part as shown in Fig. 3.

Next, the piston rod 44 of the operating cylinder 43 is extended and the movable plate 40 is lowered, and the first movable positioning plate 29 and the second movable positioning plate 30 are connected to the movable plate 40 via the chain 41.

Branch inclined lower piece 3
3 and cross each other in a staggered manner, and place wood a on the staggered intersection.
are transferred and further mutually advanced, and the branching inclined upper piece 34 of the right-angle branching support part 32 of the first movable positioning plate 29 and the branching inclined upper piece 34 of the right-angle branching support part 32 of the second movable positioning plate 30 As shown in FIG.
2 and the right angle branch support part 32 of the second movable positioning plate 30, the wood a is held between the center chuck 3 and the center of the wood a.
6. Then the working cylinder 15
, 18 are retracted, the receiving arms 10, 12 are operated to hang down and separated, and at the same time, the center chucks 36, 36 at both ends of the material conveying vehicle 3 are operated to release the center chucks 36, 36. Stick the tip into the center of the wood a, engage it, and place the center chuck 3 on the material transport vehicle 3.
6, 36 to firmly grasp the wood a, then retract the piston rod 44 of the actuating cylinder 43, and retract the first movable positioning plate 29 and the second movable positioning plate 30. The right angle branch support part 32 of the first movable positioning plate 29 and the right angle branch support part 32 of the second movable positioning plate 30 are removed from the wood a as shown in FIG. 5 after returning to the normal position. let

In this way, the center chucks 36, 36 at both ends of the material conveying car 3
The lumber a with both ends held in the center is transferred toward the band saw 52 as the lumber transport vehicle 3 moves, and is turned into desired sawn lumber.

Thus, the sequential operation of the stopper arm 48 starting with the inverted position of the wood a onto the liep roller 20 and the mutual inward movement of the receiving arms 10 and 12 form a V-shaped receiving section. , the flipper 21 is tilted up into the receiving portion and transferred from above the liep roller 20, and the right-angled branch support portion 32 and the second movable positioning plate 29 are moved inwardly toward each other. movable positioning plate 30
The center chuck center is held in alignment with the center of the wood a by holding the wood a with the right-angled branch support part 32 of the lumber a, the receive arms 10 and 12 are operated to hang down and separate, and the center chucks 36 and 36 installed at both ends of the material transport vehicle 3 The backward return operation of the first movable positioning plate 29 and the second movable positioning plate 30 after holding the wood a is carried out by the respective operating cylinders 15, 18,
23, 43 via a timer (not shown) or by activating the receiving arms 10, 12 at different times.
, limit switches (not shown) are attached to the operating parts of the flipper 21, movable positioning plates 29, 30, and stopper arm 48, and a fluid supply/discharge device (not shown) electrically connected to these limit switches By differentially operating each of the operating cylinders 15, 18, 23, and 43, each part can be automatically and sequentially operated to set the wood a at a position that fits the center chuck 36 of the material transport vehicle 3.

However, the present invention provides that each working cylinder 15, 18, 23, 4
This purpose can be sufficiently achieved by individually differentially moving the three.

In short, the present invention provides the fixing machine frames 5 and 6 facing each other on both sides of the rail 2 of the material conveying vehicle 3, and the opposing inner sides 7 and 6 of the fixing machine frames 5 and 6.
