The present invention relates to a panel processing apparatus, and more particularly to a side processing apparatus of a wood panel.

Panels of various shapes and widths are provided for furniture or doors. Conventional panels are subjected to post-processing to smooth the surface after pre-processing joining or assembling various woods such as solid wood, synthetic wood, and the like. This may optionally be followed by painting, coating or film attachment.

The present invention relates to a side processing apparatus for smoothly and precisely cutting the sides of a panel, in particular. The processing apparatus may be one of several apparatuses installed on one transfer line. In other words, the side processing apparatus of the present invention may be combined with other devices for bonding the edge tape or cutting the bonded edge tape to the width of the panel.

1 is a schematic perspective view showing the configuration of a conventional wood panel side processing apparatus.

The wood panel side processing apparatus basically includes a conveyor 100 for continuously feeding the injected wood panel (P, hereinafter referred to simply as panel) in the direction of the arrow A1. The conveyor 100 needs a means for fixing the panel P from being flowed during conveying and processing. Usually, a plurality of pressing rollers 102 for pressing the upper surface of the panel perform its function. On the side of the conveyor 100, a motor 104 (hereinafter referred to as a “cutting part”) in which a cutter is built to cut the side surface F1 of the panel is installed so as to be movable forward and backward. The cutting unit 104 is configured to linearly reciprocate in the direction of the arrow A2 by a hydraulic or pneumatic cylinder.

2 is a plan view illustrating the interaction between the cutter and the panel.

The panel is conveyed in the direction of arrow A2, and the cutting part 104 of the panel side processing apparatus approaches the panel side while making a linear movement in a direction A2 perpendicular to the conveying direction of the panel. However, the conventional apparatus in which the cutting unit makes a linear motion has the following problems. The heavy motor has a linear reciprocating motion along the arrow direction A2 by a pneumatic or hydraulic cylinder as described above, and it is difficult to precisely and precisely start the cutting section 104 by inertia by its own weight. . That is, an error was inevitable in activating the cutting unit 104. This caused a problem of non-uniformity of the cutting surface, that is, cutting of the cutting surface at the entry point of the cutter 106.

An object of the present invention for the above problems is to provide a panel side processing apparatus capable of smoothing and smoothing the side surface (F1) of the panel, which is the processing surface. Specifically, it is an object of the present invention to provide a wood panel side processing apparatus capable of uniformly cutting the surface by preventing the edges of the front and rear ends of the panel from being eaten by the cutter.

The above object is a conveyor means for transporting the wood panel; Panel fixing means for preventing the wooden panel from flowing while being transported; In the side processing apparatus of the wood panel comprising a cutting unit and a control unit for cutting the side of the panel supplied by being installed on the side of the conveyor means;

For individually moving the first and second motors; First and second shafts installed on the fixed frame in a direction perpendicular to the moving plane by the conveyor; The first and second cutters are installed between the first and second shafts and the first and second motors so as to approach or move away from the side surfaces of the wood panel while rotating the first and second axes about the shaft center. First and second rotating frames for installing the first and second shafts in parallel with the first and second shafts; Including first and second pneumatic cylinders operated by the control unit for rotating the first and second rotating frames; The first and second motors are achieved by the side processing apparatus of the wood panel, characterized in that it comprises a first and second motor starting means for accessing the side of the wood panel while rotating during processing.

Here, the control unit, the front end of the wood panel and a predetermined section therefrom is cut by a cutter that rotates in the direction opposite to the transport direction of the wood panel, the remaining section including the rear end in the same direction as the transport direction of the wood panel And controlling the first and second motor starting means to cut by the rotating cutter.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. 3 is a partial perspective view of a side processing apparatus of a wood panel according to an embodiment of the present invention. Fig. 4 shows a state where it is not processed as part of the plan view. 5 is a plan view showing a machining state. 6 is an assembly view of the cutting unit of the side processing apparatus of the wooden panel according to an embodiment of the present invention.

The side processing apparatus of the wood panel, the conveyor means for conveying the wood panel (P) (2); Panel fixing means for preventing the wooden panel from flowing while being transported; And a cutting unit 4 and a control unit for cutting the side surface of the panel supplied by being installed on the side of the conveyor means.

Conveyor means (hereinafter, referred to as 'conveyor') is a concept for including a drive unit for passing the wood panel through the processing unit (cutting unit). The difference from the conventional conveyor apparatus is that it further includes panel fixing means for preventing the wooden panels (hereinafter referred to as panels) from flowing during transportation. The panel fixing means is known and includes a plurality of pressing rollers 6 for pressing the upper surface of the panel. Since the conveyor means 2 is well known in its entirety, a detailed description thereof will be omitted.

The cutting part 4 is for cutting the side surface F1 of the panel P to be conveyed to a constant depth like a milling machine, and is fixedly installed at the midpoint side of the conveyor 2. The cutting unit 4 includes a fixed frame 8, first and second motors 10 and 12, first and second cutters 14 and 16, and first and second motor starting means 18 and 20. The fixed frame 8 is fixed to the side of the conveyor 2 to woven the cutting portion 4 into one body, in which several components are three-dimensionally assembled.

The first and second motors 10 and 12 are installed upright on both left and right sides of the fixing frame 8 so as to be movable back and forth in a direction perpendicular to the side surface F1 of the wood panel. In the first and second motors 10 and 12, the respective rotary shafts 22 and 24 are installed perpendicularly to the moving plane M by the conveyor 2. The capacity of the first and second motors 10 and 12 is set according to the thickness of the panel P. FIG. Therefore, in order to process the thick panel (P), a large motor must be used. The first and second motors 10 and 12 are different from each other in the rotational direction, and the first motor 10 rotates in the clockwise direction and the second motor 12 rotates in the counterclockwise direction. First and second cutters 14 and 16 are arranged on the rotation shafts 22 and 24 of the first and second motors, respectively. Thus, the first and second cutters 14 and 16 also rotate in different directions.

First and second motor starting means 18, 20 for separately moving the first and second motors 10, 12 are provided. According to an embodiment of the present invention, the first and second motor starting means 18 and 20 approach or move from the side surface F1 of the wood panel while the first and second motors 10 and 12 rotate in opposite directions, respectively. To be spaced apart.

To this end, the first and second shafts 26 and 28 are installed on the fixed frame 8 in a direction perpendicular to the moving plane M by the conveyor 2. The first and second pivot frames 30 and 32 approach the side surfaces F1 of the wood panel while allowing the first and second cutters 14 and 16 to pivot the first and second shafts 26 and 28 in the axial center. It is installed between the first and second shafts 26 and 28 and the first and second motors 10 and 12 so as to move away from or away from it.

 The first and second pneumatic cylinders 34, 36, or hydraulic cylinders, hereinafter simply referred to as 'cylinders', are operated by the control unit to rotate the first and second pivoting frames 30 and 32. One side of the first and second cylinders 34 and 36 is rotatably fixed to one side of the fixed frame 8 or a non-illustrated fixed portion, and the other side is perpendicular to the first and second rotating frames 30 and 32. Supported. The first and second cylinders 34 and 36 may rotate the first and second pivot frames 30 and 32 by varying their lengths in the installed state as shown.

The fixing frame 8 is composed of an upper plate 38, a lower plate 40, and a side plate 42. The first and second shafts 26 and 28 are fixed at both ends between the upper plate 38 and the lower plate 40. . The upper plate 38 and the lower plate 40 are fixed in a state spaced apart by a predetermined height by the first and second shafts 26 and 28 and the central rod 46 arranged in parallel in a planar triangular sphere. Bearing members 48 and 50 are slidably fitted to the outer circumference of the first and second shafts 26 and 28, and the bearing members 48 and 50 are mounted on the first and second pivot frames 30 and 32, respectively. It is fixed. The intermediate plate 52 is further interposed between the upper plate 38 and the lower plate 40. The intermediate plate 52 is fixed to the bearing members 48 and 50, and is installed to be slidably movable through the bearing member which is different from the center rod 46. As a result, the intermediate plate 52, the first and second pivot frames 30 and 32, and the first and second motors 10 and 12 are integrated to be able to be started up and down with respect to the fixed frame.

Meanwhile, the intermediate plate 52 is connected to the height adjusting bolt 54 installed to penetrate the upper plate 38 in the vertical direction. The user is able to adjust the height of the intermediate plate 52 using the height adjustment bolt (54). As a result, the first and second pivot frames 30 and 32 connected to the bearing members 48 and 50 and the first and second motors 10 and 12 connected thereto are also adjusted by the height adjusting bolt 54 in the vertical direction. I can do it.

The side plate 42 connected to the upper plate 38 is provided with a flat plate-shaped bracket 56 horizontally. The bracket 56 is provided with limit means for limiting the rotation angles of the first and second rotation frames 30 and 32. This limit means can be satisfied with the rotation angle adjusting screw 60 penetrating vertically through both blades 58 of the bracket 56. That is, by adjusting the fastening depth of the rotation angle adjusting screw 60, it is possible to limit the rotation angle by selectively touching the rotation frame (30, 32).

Operation according to the configuration of the present invention will be described with reference to FIG.

FIG. 5A is for explaining a step in which the front end portion P1 of the panel is cut by the first cutter 14. When the panel P enters the cutting unit 4 along the conveyor 2, the control unit detects this and operates the first cylinder 34 to operate the first rotating frame 30 and the first motor connected thereto. Rotate 10). The first motor 10 then rotates the first shaft 26 in an axial center with an arc, thereby adjoining the first cutter 14 to the side surface F1 of the tip portion P1 of the panel. The rotation angle will be set here according to the required cutting amount.

At this time, since the conveyance (entry) direction of the panel P and the rotation direction of the first cutter 14 are opposite, the front end portion P1 of the panel can be smoothly cut. The 1st cutter 14 processes the side surface F1 of a panel independently of the front-end | tip of a panel, and continuous continuous from it. Here, the second cutter 16 is in the air spaced apart from the panel in a state of being stopped or rotated.

At some point in time, the controller operates the second cylinder 36 to rotate the second rotating frame 32 and the second motor 12 connected thereto as shown in FIG. 5B. Then, the second motor 12 rotates the second shaft 28 to the center of the shaft, thereby causing the second cutter 16 to be adjacent to the side surface F1 of the panel. The second cutter 16 is moved to the position necessary to cut the side of the panel simultaneously or alternately with the first cutter 14. However, at least the rear end portion P2 of the panel is cut by the second cutter 16 alone or at the front. The second cutter 16 rotates in the same direction as the conveying direction of the panel and cuts the rear end portion P2 of the panel. Therefore, the edge of the rear end portion P2 is pushed away by the second cutter 16 so as not to fall off.

In some cases, the first cutter 14 and the second cutter 16 may be in the machining position at the same time. In this case, the second cutter 16 is processed and the first cutter 14 is to be idling. That is, since the second cutter 16 first touches the side surface of the panel and the first and second cutters 14 and 16 have the same depths of cut.

The operation time of the second cylinder 36 may be set in advance by the operator according to the length of the panel P, or may be automatically determined by detecting the length of the panel in the device itself by the sensing means.

In conclusion, at least the point in time when the second cylinder 36 moves the second pivot frame 32 and the second cutter 16 is the rear end portion after the front end portion P1 of the panel passes through the first cutter 14. It will have to be set before P2 passes through the second cutter 16. And the point of releasing its operation (separating from the panel) should be before the subsequent panel P 'enters the second cutter 16.

In an embodiment of the present invention, the first and second cylinders 34 and 36 allow the first and second pivot frames 30 and 32 to be 5 ° to 10 ° about the first and second axes 26 and 28. Rotate in range. The first and second cutters 14 and 16 rotate in an arc shape in the section thereof and are in contact with the side surface F1 of the panel. Since the operating direction of the first and second cylinders 34 and 36 and the moving direction of the first and second motors 10 and 12 are different from each other as described above, the inertia force due to the start of the heavy first and second motors 10 and 12 This will work less. That is, since the weights of the first and second motors 10 and 12 do not act on the first and second cylinders 34 and 36, the first and second cylinders 34 and 36 have a very small force. 10, 12) can be activated. Therefore, precise movement of the first and second motors 10 and 12 is possible.

According to the above configuration, in the side processing of the wooden panel for furniture or doors, the edges of the front and rear ends are pushed by the cutter so that they do not partially fall off, and the cutting surface is made uniform by making the cutting part approach the side of the panel. A side processing apparatus for the wood panel is provided. That is, there is almost no impact when entering the cutting position of the second cutter 16, so that the cutting surface becomes uniform.
