Description

Panel cutting device for edge banding machine {APPARATUS FOR CUTTING PANEL FOR EDGE BANDING MACHINE}

The present invention is for an edge banding machine for uniformly cutting the edge surface of the panel before attaching the edge band to the edge surface of the panel among the devices of the edge banding machine to transfer and attach the edge band to the edge surface of the panel, and to cut and trim It relates to a panel cutting device.

Panels are formed to have a predetermined area and thickness for use in manufacturing furniture. By cutting and assembling these panels and using them as walls and partitions, furniture having a desired shape is produced.

In view of recent trends, the panel has been widely used as a material, such as artificial wood, for example, medium-density fibreboard (MDF), particle board (PB), etc., due to cost reduction and improvement of processing technology.

These artificial woods are surface treated to form various colors and patterns on the front and rear surfaces. In addition, since the raw material is exposed to the edge surface of the panel, that is, the side surface is not particularly surface treated, the edge band is attached to the edge surface of the panel through an edge banding machine.

In order to finish the decorative border of the panel as described above, the edge band of the finishing treatment, such as PP, PVC, veneer, pattern paper, etc. are attached to the edge surface of the panel with an adhesive. The equipment for attaching the edge band to the edge surface of the panel and cutting the edge band according to the length and thickness of the panel is generally called an edge banding machine.

The edge banding machine is a panel conveying apparatus installed with a conveyor moving in an endless track and a plurality of conveying rollers rotatably installed on the conveyor, and a cutting to uniformly cut the edge surface of the conveyed panel without irregularities. A panel cutting device equipped with a means, an edge band supply device for supplying an edge band to the edge surface of the cut panel, an adhesive applied to the edge surface of the panel, and an edge band fed from the edge band supply device. An edge band attachment device for pressing and attaching to the edge surface of the panel, an edge band cutting device for cutting both ends of the edge band attached to the edge surface of the panel to the length of the panel, and an edge band attached to the panel Edge band trimming device for trimming the edge protruding up and down in accordance with the thickness of the, and the edge band trimming field Removing the adhesive agent adhering to the peripheral edge of the panel through the apparatus consists of a buffing.

Among the devices of the edge banding machine configured as described above, the panel cutting device includes a flat milling cutter or a rotary saw which is rotated by a rotary motor as shown and described in the prior art patent documents 1 and 2, and the edge surface of the panel being conveyed. Before the edge band is attached to the cutting edge, cut it evenly without irregularities.

When the panel is cut by the panel cutting device, there is no problem when the edge bands are not attached to the front and rear ends of the panel, respectively, but as shown in FIG. 1, the front and rear ends of the panel P are shown. In the case where the edge bands B are attached to each other, there is a problem in that the edge bands B of the front end face or the rear end face fall from the panel P regardless of whether they are flat milling cutters or rotary saws. That is, an edge banding machine equipped with a panel cutting device cuts one edge surface of the panel P uniformly without irregularities, attaches an edge band B, and combines the other edge surfaces to process a total slope. do. Therefore, after machining one side or more than one side, when the machining is started on the other side, the cutting process is performed with the edge band B attached to the front or rear or front and rear ends of the panel P being transferred. It is beginning.

In consideration of the processing conditions described above, if the edge bands B and B 'are attached to both front and rear end surfaces of the panel P, in the case of a rotary saw or a flat milling cutter that is simply fixed and rotated, the panel P It is easy to prevent the separation of the edge band (B) attached to the front end surface of the front and rear both ends, but as shown in Figure 1 to prevent the separation of the edge band (B ') attached to the rear end surface of the panel (P) It's hard to do. In order to solve this problem, a panel cutting device for edge banding machines such as Patent Documents 1 and 2 has been applied.

In case of Patent Literature 1, two pairs of flat milling cutters are provided, and the rear flat milling cutter is cut up from the front edge of the panel to the middle with respect to the edge of the panel to be transported forward, and the front flat milling cutter is The edge of the edge is cut down from the middle to the rear edge. However, in case of Patent Literature 1, two pairs of flat milling cutters are provided, so that the length of the overall edge banding machine is considerably lengthened to operate without interference, and the up and down cutting of one side of the edge of the panel is performed. Since the change is performed in the middle, the cut surface of the front and rear parts of the panel is different, so that the edge of the panel is not uniform, and thus the edge band is not properly attached.

Due to the fatal problem of Patent Document 1, in the case of Patent Document 2 filed and registered by the present applicant, the center of rotation of the rotary saw is lifted above and below the edge of the panel to be transferred along the direction of rotation through a single rotary saw. It was configured to. Unlike patent document 1, in case of patent document 2, the fatal problem that the length of the device is increased or the surface texture is different is clearly overcome, but the problem of detachment of the edge band attached to the rear end surface of the panel still being transferred is not completely overcome. That is, regardless of whether the rotary saw is rotated clockwise or counterclockwise, the center of rotation of the saw is in contact with the edge band attaching surface of the rear end of the panel that is transported at any time above or below the edge of the panel. There is a problem that the minimum detachment of the edge band attached to the rear end is inevitable.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the panel cutting device for edge banding machine according to the present invention.

Panel cutting device for an edge banding machine according to the present invention, as shown in Figure 2 comprises a conveyor 100, a transfer roller 200 and a cutting means 300, the cutting means 300 is a flat milling It may be composed of a cutter 310 and the pressing member 330, or as shown in Figure 11 and 12 may be composed of a rotary saw 320 and the pressing member 330. In addition, the cutting means 300 may further include a lifting cylinder 340, forward and backward cylinder 350, a limit switch 360 and a control unit (not shown).

First, the panel cutting device for edge banding machine according to the present invention is the edge band on the edge surface of the panel P among the devices of the edge banding machine to transfer the edge band to the edge surface of the panel P, and then attach and cut and trim. The device is installed to evenly cut the edge surface of the panel (P) before attaching.

The panel cutting device for the edge banding machine as described above is conveyed forward by the conveyor 100 and the plurality of feed rollers 200 rotatably installed on the conveyor 100 as shown in FIG. Cutting means 300 for cutting the surface of the panel P to be uniform without irregularities is provided.

The cutting means 300 will be able to uniformly cut the edge surface of the panel (P) to be transported only when a cutter (rotating) is provided at least. As a cutter of the cutting means 300, the first embodiment of the present invention uses the flat milling cutter 310, and the second and third embodiments of the present invention use the rotary saw 320.

However, when the cutter is used as a flat milling cutter 310 according to the first embodiment of the present invention, the flat milling cutter 310 has a rotary center axis in the vertical direction as shown in FIG. It is installed to face the edge surface of the panel (P) is constantly cut up from the front edge to the rear edge of the panel (P).

The flat milling cutter 310 can be cut up or down with respect to the feed direction of the raw material. Up-cutting refers to a case in which the rotation direction of the cutter blade, that is, the direction of cutting is opposite to the feed direction of the workpiece, and is cut downward. Refers to the case where the rotation of the canal and the conveying direction of the workpiece are in the same direction.

That is, in the first exemplary embodiment of the present invention, as shown in FIG. 2, since the rotation direction of the cutter blade of the flat milling cutter 310 is opposite to the conveying direction of the panel P, the edge surface of the panel P is upward. Will be cut. The reason why the flat milling cutter 310 is upwardly cut with respect to the edge surface of the panel P is to prevent separation of the edge band B attached to the front end surface of the panel P. This is widely used in the art. come.

However, the flat milling cutter 310 according to the first embodiment of the present invention merely finishes the edge surface of the panel P by constantly cutting up from the front end to the rear end. At this time, if the edge surface of the panel P, which is transferred to only one flat milling cutter 310, is completed by upward cutting, a problem of separation of the edge band B 'attached to the rear end surface of the panel P may occur. This can be surely solved through the pressing member 330 to be described later.

Meanwhile, in the second and third exemplary embodiments of the present invention, a cutter for uniformly cutting the edge surface of the panel P may also be used as the rotary saw 320. Of course, unlike the flat milling cutter 310 of the first embodiment, in the case of the rotary saw 320 of the second and third embodiments, the center of rotation of the circular saw blade is horizontally laid so that one surface of the circular saw blade is the edge of the panel P. It is installed to face the surface is constantly cut from the front edge to the rear edge of the panel (P). However, in the case of using the rotary saw 320, the rotation center axis of the rotary saw 320 to prevent the separation of the edge band (B) attached to the front surface of the panel (P) according to the rotation direction of the rotary saw 320 The installation position of (G) may be different.

That is, referring to FIG. 11, in which the second embodiment of the present invention is shown, the center of rotation of the saw blade when the saw blade rotates counterclockwise in the direction in which the rotary saw 320 faces the panel P 320 should be installed to be located below the bottom edge of the panel (P). On the contrary, referring to FIG. 12 where the third embodiment of the present invention is shown, when the saw blade rotates clockwise in the direction in which the rotary saw 320 faces the panel P, the axis of rotation of the saw blade ( 320 should be installed above the upper edge of the edge of the panel (P).

The edge band B attached to the front end surface of the panel P to be conveyed regardless of whether the cutters of the second and third embodiments as well as the flat milling cutter 310 or the rotary saw 320 are the case of the first embodiment described above. It will not be a problem to prevent the departure of the problem, but if a constant cutting to the rear end of the edge of the panel (P) can not solve the problem of separation of the edge band (B ') attached to the rear end of the panel (P). This can be solved simply through the pressing member 330 as described above.

That is, the pressing member 330 is the edge of the panel (P) by the flat milling cutter 310 when the cutter is a flat milling cutter 310 as shown in Figures 3 to 7 which is a first embodiment of the present invention After the front end is cut and before the edge edge of the panel P is cut, the panel P is contacted with the edge of the edge of the panel P to press the rear surface of the panel P, with the transfer of the panel P. Move forward. Of course, even when the cutter is a rotary saw 320 as shown in Figures 11 and 12 of the second and third embodiments of the present invention, the pressing member 330 is the panel (P) by the rotary saw 320 After the front edge of the edge is cut, before the edge edge of the panel P is cut, the back of the panel P is contacted with the rear edge of the panel P, and the conveyance of the panel P is carried out. Move forward with.

When the rear surface of the panel P is pressed by contacting the rear end of the panel P through the pressing member 330, the edge band B ′ attached to the rear end surface of the panel P is pressed by the pressing member ( 330 is pressed and the state is pressed. Therefore, the edge band B attached to the rear end surface of the panel P regardless of whether the cutter for cutting the edge surface of the panel P is the flat milling cutter 310, the rotary saw 320, the up cutting or the down cutting. ') Is pressed against the pressing member 330, so that there is no room for the edge band B' to be separated from the rear end surface of the panel P.

Since the pressing member 330 as described above should be able to continuously operate with respect to the other panel P which is conveyed again and again with the transfer of the panel P, the pressing member 330 is provided with a driving unit for driving the function. Should be.

That is, as illustrated in FIGS. 2 to 12, the elevating cylinder 340 for elevating the pressing member 330 up and down, and the forward and backward cylinder 350 for moving the elevating cylinder 340 forward and backward are further included. Lifting cylinder 340 is directly coupled to the pressing member 330 to move the pressing member 330 up and down as the name, the front and rear cylinders are also installed to move the pressing member 330 back and forth as the name. . However, since the pressing member 330 is directly connected to the lifting cylinder 340, when the lifting cylinder 340 moves forward and backward, the pressing member 330 also moves back and forth, so that the forward and backward cylinder 350 moves the lifting cylinder 340. It is installed to advance back and forth.

When the pressing member 330 is moved up and down by the elevating cylinder 340 and the forward and backward cylinder 350, the control unit for controlling whether to detect and operate the proximity of the panel (P) at what time point (not shown) C) and limit switch 360 are required.

The limit switch 360 is fixed to the front of the lifting cylinder 340, and detects the proximity of the rear end of the panel (P) to be transferred. In more detail, as shown in FIG. 4, the panel P continuously moves while the front end of the initial panel P contacts the limit switch 360, and then the panel P as shown in FIG. 5. When the rear end of is released from the contact of the limit switch 360, the rear end of the panel (P) is detected by the limit switch 360 close. Of course, although the name is referred to as the limit switch 360, it is sufficient if the sensor that can detect the proximity of the rear end of the panel (P) irrespective of any other type of contact sensor or non-contact sensor.

Although not shown separately in the drawings, the control unit is a microcomputer driven by a program preset to receive a signal or transmit an operation signal from each component. The driving of the controller will be described in detail with reference to FIGS. 3 to 9.

In the case of FIG. 3, the panel P is only transferred by the conveyor 100 and the transfer roller 200. In the case of FIG. 4, the front end of the panel P continuously contacts the limit switch 360. Move. In this case, a signal that the front end of the panel P is first detected from the limit switch 360 is transmitted to the controller.

In the case of FIG. 5, as the panel P is continuously transferred forward, the rear end of the panel P is released from the limit switch 360. Accordingly, the limit switch 360 sends a signal to the controller that the rear end of the panel P is close.

As shown in FIG. 6, the control unit receives a signal from the limit switch 360, and when the rear end of the panel P passes the lifting cylinder 340 according to a preset feed rate of the panel P, the lifting cylinder 340. Operate 340 to lower the pressing member 330.

As shown in FIG. 7, when the pressing member 330 is lowered by the lifting cylinder 340, the control unit operates the forward and backward cylinder 350 to move the lifting cylinder 340 to the front, thereby allowing the pressing member to move forward. 330 contacts the rear edge of the panel P and simultaneously presses the rear surface of the panel P to move forward with the transfer of the panel P. At this time, even if there is a certain gap between the pressing member 330 and the rear end of the panel P during the initial lowering of the pressing member 330, the forward movement of the pressing member 330 by the front and rear vibration cylinder 350 is the panel. Since it is faster than the conveyance speed of (P), when the edge end of the panel P is cut by the cutter, the pressing member 330 is in a state of pressing the rear end surface of the panel P.

As described above, in the state where the pressing member 330 presses the rear end surface of the panel P, the edge surface of the panel P is completely cut from the front end to the rear end by the cutter, and then the control unit as shown in FIGS. 8 and 9. As a result, the lifting cylinder 340 and the forward and backward cylinder 350 are operated in turn. That is, the control unit controls to return to the rear by operating the forward and backward cylinder 350 after operating the lifting cylinder 340 to raise the pressing member 330 when the forward movement of the forward and backward cylinder 350 is completed. do.

By repeating the above process continuously while cutting the edge surface of each panel (P) evenly conveyed, the rear end surface of the panel (P) is pressed by the pressing member 330, so the rear end surface of the panel (P) It is possible to reliably prevent the separation of the edge band (B ') attached to the.

On the other hand, the pressing member 330 may be in the form of a square column vertically as shown in Figures 2 to 12 to be pressed in surface contact with the rear end surface of the panel (P), the material is made of wood, such as panel (P) It may be coupled to the lifting cylinder 340 by using the cut-out of the panel P with plywood or the like. At this time, the pressing member 330 is satisfied only the uniformity of the surface in contact with the rear end surface of the panel (P), other side processing is not a problem. For example, even when the front surface of the pressing member 330 is slightly protruded, as shown in FIG. 10, the edge surface of the first panel P is cut while the pressing member 330 is initially installed in the lifting cylinder 340. This is because the front surface of the pressing member 330 is also cut together, and the front surface of the pressing member 330 is already uniformly cut from the cutting of the edge surface of the second panel P. FIG.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
