Description

  The present invention ensures that a part of the wood chips jumps out of the dust collector when the wood is cut by the dust collector for the wood precut equipment, in particular, the precut equipment provided with the wood dust collector. The present invention relates to a dust collector for wood precut equipment that can be prevented.

  FIG. 5 shows an example of a wood precut device that automatically cuts wood used in a wooden frame construction method for a house based on preset processing data. This precut device is provided with a length cutting machine 2, an intermediate processing machine 3, a first end processing machine 5A and a second end processing machine 5B, and is set in advance as follows. Based on the data, the wood (W1) is automatically cut.

  The wood (W1) carried into the processing line (L) from the carry-in machine 1 is cut into a predetermined length by the length cutting machine 2 and then transported to the intermediate processing machine 3, where vertical machining, Processing such as horizontal processing and grooving is performed. The wood (W1) whose intermediate portion has been processed by the intermediate portion processing machine 3 is carried into the first end portion processing machine 5A by the intermediate transfer device 4, where one end portion is subjected to a kerf processing, and then Then, it is carried into the second end processing machine 5B, where the other end is subjected to a butt end processing. In this way, the processed wood (W2) for which all processing has been completed is carried out of the processing line (L) by the unloader 6.

  According to the pre-cut device, the wood (W1) is cut by the blade that rotates at a high speed, so that a large amount of wood chips scatters in all directions. The scattering of wood chips is dangerous and soils the surroundings. Therefore, in order to prevent the scattering of wood chips, a wood dust collecting device is installed in the cutting part of the wood (W1).

  Hereinafter, a conventional dust collector that collects wood chips generated during the cutting of wood (W1) will be described with reference to the drawings.

  As shown in FIG. 6, this conventional dust collector is composed of a rectangular parallelepiped box 7 and a plate cover 8 that cover the end of the wood (W1). The box 7 is fixed vertically at a fixed position, and the upstream surface (S1) is formed with a rectangular wood opening 7B through which the end of the wood (W1) is inserted, and the downstream surface (S2) is The wood dust discharge duct 7A is provided at the bottom. The discharge duct 7A is connected to a suction blower (not shown). The cover 8 has a plurality of circular blade openings 11 through which cutting cutters 10 rotated by a motor 9 enter and exit, that is, four in this example, one vertical row for every four different cutters 10. Are formed at intervals. The cover 8 closes the open downstream surface (S2) of the box 7 and matches the processed shape of the lip in the Z-axis direction (vertical direction) and Y-axis direction (front-rear direction) as shown in the figure together with the motor 9 and the cutter 10. And move in close contact with the downstream surface (S2). Each blade 10 moves with the motor 9 that drives the blade 10 independently in the illustrated X-axis direction (left-right direction), and is selected according to the shape of the cut end.

  When the blade is selected, the selected blade 10A is moved to the position facing the wood mouth (M) in the box 7 to the cover 8, the motor 9A for driving the blade 10A, the other blade 10 and the motor 9 thereof. Move with. Thereafter, the selected blade 10A moves together with the motor 9A toward the wooden mouth (M) in the box 7 through the opening 11A in the X-axis direction. In this way, when the blade 10A moves to a predetermined position, the selected blade 10A is selected from the cover 8, the motor 9A for driving the blade 10A, the other blade 10 and the scraper based on the preset machining shape data. The motor 9 moves in the Y and Z axis directions. Thereby, a desired end processing is performed on the end (M) of the wood (W1). All of these operations are automatically performed by commands from a controller (not shown).

  According to the conventional dust collector, the wood chips generated during the cutting of the mouth (M) of the wood (W1) are accumulated in the box 7 and are not scattered around. Wood chips in the box 7 are discharged out of the box 7 by suction from the exhaust duct 7A.

  According to the conventional dust collector, as described above, since the end of the wood (W1) is covered with the box 7 and the cover 8, most of the wood chips generated at the time of cutting the mouth end are boxed. However, some wood chips jump out of the box 7. That is, in the opening 11 formed in the cover 8, the rotation shaft of the cutting tool 10 that is cutting is inserted into the opening 11 </ b> A that directly faces the mouth, so that wood chips are outside the box 7 from the opening 11 </ b> A. However, since the other openings 11 are opened as they are, there is a problem in that wood chips easily jump out of the box 7 from here.

  Therefore, the object of the present invention is to reliably prevent a part of the wood chips from jumping out of the dust collector when the wood is cut by the pre-cut equipment equipped with the wood dust collector. An object of the present invention is to provide a dust collector for precut equipment.

  The inventor of the present application has intensively studied to solve the above-mentioned problems. As a result, if a cylinder is attached to each of a plurality of openings formed in the cover that closes the box, and a cutting tool is inserted into the cylinder of the opening that does not face the machined part during cutting, these openings are closed. As a result, it is possible to prevent some wood chips from jumping out of the box from the opening that is not directly facing the machined part, and a seal in which slits are radially formed in each cylinder or each opening. The knowledge that it was possible to more reliably prevent the wood chips from popping out by attaching the material was obtained.

  The present invention has been made on the basis of the above findings, and is characterized by the following.

The invention according to claim 1 includes a box body that covers a processed portion of wood, at least one surface being an open surface, and a plate-like cover that closes the open surface of the box body.
