Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lumber inverting device, which is used when inverting lumber such as timber around an axis.

[0002]

[Prior art]

 Conventionally, inverting lumber such as timber around the axis has been done by the work of multiple workers.

[0003]

[Problems to be solved by the device]

 However, since the timber and the like are extremely heavy, such conventional reversing work is time-consuming and requires great care, and as a result, it is difficult to improve the work efficiency.

An object of this invention is to eliminate such inconvenience.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in a square bar reversing device according to the present invention, a pair of rotating shafts are installed in parallel to a frame, and a plurality of mounting members are installed on these rotating shafts. A pair of mounting levers projecting in a substantially vertical state, the adjacent mounting levers of the rotating shafts are arranged in a staggered manner, and these mounting levers are made substantially equal to the distance between the pair of rotating shafts. By rotating the rotary shaft by an appropriate means, the mounting member is alternately swung at an angle of about 90 °.

[0006]

[Action]

 Since the square bar reversing device according to the present invention is configured as described above, the lever on the front side of the mounting member is set in the horizontal state and the lever on the other side is set in the vertical state on the first and second rotating shafts. To do. Then, a square member is placed on the first placing member, and the first rotating shaft is swung 90 degrees away. At this time, the timber is turned 90 degrees and placed on the lever on the front side of the second placing member. In this state, the second rotary shaft is rotated to swing the second mounting member 90 degrees away, and the square bar is further inverted 90 degrees. As a result, the square bar is rotated around the 180 degree axis.

【Example】

 In FIGS. 1 and 2, A is a square bar reversing device and F is its frame.

Reference numeral 1 denotes a first rotating shaft, which is rotatably installed at the right end portion (in the figure) of the frame F via bearings 11, 11. Reference numerals 12 and 12 are sprockets installed on the first rotary shaft 1.

Reference numeral 13 denotes a first swing shaft, which is installed below the first rotary shaft 1 in the frame F. The first swing shaft 13 is rotated by the retracting movement of the piston / cylinder mechanism 132 via the first swing lever 131. Reference numeral 133 is a sprocket installed on the first swing shaft 13.

Reference numeral 14 denotes a chain, which is hung between a sprocket 12 of the first rotary shaft 1 and a sprocket 133 of the first swing shaft 13. Therefore, the first rotary shaft 1 rotates with the rotation of the first swing shaft 13. The range of rotation of the first rotary shaft 1 is approximately 90 degrees.

A mounting member 15 is fixed to both ends of the first rotating shaft 1. The mounting member 15 has a pair of mounting levers 151 and 152 protruding in a substantially vertical state. The mounting member 15 supports the timber W by a pair of mounting levers 151 and 152 and rotates it by 90 degrees.

Next, 2 is a second rotary shaft, which is rotatably installed on the left side (in the drawing) of the first rotary shaft 1 via bearings 21 and 21. Reference numerals 22 and 22 are sprockets installed on the second rotary shaft 2.

Reference numeral 23 denotes a second swing shaft, which is installed below the second rotary shaft 2 in the frame F. The second swing shaft 23 is rotated by the retracting movement of the piston / cylinder mechanism 232 via the second swing lever 231. Incidentally, 233 is a sprocket installed on the second swing shaft 23.

Reference numeral 24 denotes a chain, which is hung between a sprocket 22 of the second rotary shaft 2 and a sprocket 233 of the second swing shaft 23. Therefore, the second rotary shaft 2 rotates with the rotation of the second swing shaft 23. The range of rotation of the second rotary shaft 2 is approximately 90 degrees, like the first rotary shaft 1.

25 is a mounting member and is fixed to both ends of the second rotating shaft 2. The mounting member 25 is formed by a pair of mounting levers 251 and 252 protruding in a substantially vertical state. The placing member 25 supports the timber W by a pair of placing levers 251, 252 and rotates it by 90 degrees.

The mounting member 15 of the first rotating shaft 1 and the mounting member 25 of the second rotating shaft 2 are arranged so as to be offset from each other. The distance between the first rotary shaft 1 and the second rotary shaft 2 is slightly shorter than the length of each of the mounting levers 152 and 251.

Next, 3 is a guide rod, which is installed on the left side (in the drawing) of the second rotary shaft 2 in the frame F. A slide member 5 is installed on the guide rod 3 so as to be retractable. The slide member 5 is operated by a piston / cylinder mechanism 51 installed on the frame F.

Reference numeral 6 denotes an extruding tool, which is fixed to the slide member 5 and projects to the upper surface of the frame F. The pushing tool 6 pushes the lumber W to the left by the operation of the piston / cylinder mechanism 51.

Reference numeral 7 is an outer frame of the frame F.

Next, the operation of this timber reversing device will be described.

In the first rotary shaft 1 and the second rotary shaft 2, the mounting levers 151, 251 of the respective mounting members 15, 25 are arranged in a horizontal state, and the push-out tool 6 is in a state of imaginary line. So that

Then, the square member W is placed on the placing member 15 of the first rotating shaft 1 and is swung in a counterclockwise direction by 90 degrees. At this time, the square bar W is inverted by 90 degrees and placed on the placing lever 251 of the placing member 25 on the second rotating shaft 2. In this state, the second rotary shaft 2 is rotated to swing the mounting member 25 counterclockwise by 90 degrees, and the square bar is further reversed by 90 degrees. As a result, the square bar W is rotated about the axis of 180 degrees, and is placed in front of the pushing tool (imaginary line) 6. When the piston / cylinder mechanism 51 is operated in this state, the lumber W is pushed to the left.

[Effect of device]

 In the square bar reversing device according to the present invention, a pair of rotating shafts are installed in parallel with each other on a frame, a plurality of mounting members are installed on these rotating shafts, and a pair of mounting levers are placed substantially vertically on the mounting members. The mounting levers are provided so as to project, and the mounting levers adjacent to each other of the rotating shafts are displaced and arranged, and the mounting levers are made substantially equal to the interval between the pair of rotating shafts, and the rotating shafts are rotated by appropriate means. As a result, since the mounting member is alternately rocked at an angle of approximately 90 °,

On the first and second rotary shafts, the lever on the front side of the mounting member is set in the horizontal state and the lever on the other side is set in the vertical state. Then, a square member is placed on the first placing member, and the first rotating shaft is swung 90 degrees away. At this time, the timber is turned 90 degrees and placed on the lever on the front side of the second placing member. In this state, the second rotary shaft is rotated to swing the second mounting member to the other side by 90 degrees, and the square bar is further inverted by 90 degrees. As a result, the square bar is rotated around the 180 degree axis.

[0025] Therefore, by using this square bar reversing device, the square bar can be reversed to the circumference of its axial center by mechanical operation, so that any person can easily perform the operation of reversing the square bar, resulting in an improvement in work efficiency. Can be made.
