BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sizer device used in a process of performing a sizer process on a manufactured wooden panel as an object to be processed when manufacturing the wooden panel.

[0002]

2. Description of the Related Art Generally, a wooden panel used in a prefabricated house or the like is made by attaching face materials to both sides of a frame body assembled into a rectangular contour. The produced wooden panel is sent to a sizer device, where the four end faces are respectively sized and finished to a predetermined size.

As a conventional sizer device, for example, horizontal sizer blades are provided on both sides of a first transport path for transporting a wooden panel, and front and rear portions of a second transport path following the first transport path are provided. There is a configuration in which a vertical sizer blade is provided. In addition, the sizer blade is a circular saw-shaped one that roughly has a disk-shaped blade and a motor for rotating the blade, so that both ends of the wooden panel are sizer processed by the rotation of the blade. It is composed of.

According to such a sizer device, the sizer processing is usually performed as follows. That is, the manufactured wooden panel is sent to the transport path, and the transported wooden panel is size-processed on both side end surfaces by the horizontal sizer blades arranged on both sides of the first transport path while being transported on the first transport path. . Then, it is sent to the second transport path, and here the front and rear end faces of the wooden panel are sizer-processed by the vertical sizer blade.

[0005]

However, in the conventional sizer device, the wooden panel is passed between the rotary blades to perform the sizer processing, and the wooden panel is cut without being fixed. Therefore, the cut surface may be wavy or rough, and it is difficult to obtain a highly accurate finished surface.

When the size of the wooden panel to be processed changes, the rotary blade must be moved to adjust the distance between the rotary blades, and the movement adjustment of the rotary blade takes time. Therefore, there is a drawback that cannot be dealt with promptly.

The present invention has been made in view of the above circumstances. Since the object to be processed can be positioned and fixed in a pre-cutting step with high accuracy, high-precision cutting can be performed.
Moreover, it is an object of the present invention to provide a sizer device that can perform highly accurate cutting processing even when the size of an object to be processed changes.

[0008]

In order to achieve the above object, the present invention provides a table for transporting and fixing an object to be processed, positioning means for positioning the object to be processed at a predetermined position on the table, and A fixing means for fixing the object to be processed positioned by the positioning means at that position; a sizer blade support base arranged near the peripheral side surface of the table and linearly traveling along the peripheral side surface of the table; It is attached to the sizer blade support and is aligned with the sizer blade support.
A sizer for physically cutting and cutting an end surface of the object to be processed fixed by the fixing means , wherein the positioning means includes the sizer blade support base and the table on the side to which the sizer blade support base is attached. each corner portion is provided on the stopper and the table provided and the by pressing transferring the object to be processed both ends of該被treated from the transfer means are brought into contact with the respective stopper <br/> Pas It is characterized by being configured.

[0009]

According to the sizer of the present invention, when a panel-shaped object to be processed is conveyed onto the table, the object to be processed is first positioned at a predetermined position on the table by the positioning means, and then fixed by the fixing means. It will be fixed in that position. The end surface of the object to be processed is cut by the sizer blade attached to the sizer blade support base when the sizer blade support base linearly moves along the circumferential side surface of the table.

As described above, since the object to be processed is fixed and cut on the table once, excellent cutting can be performed.
Highly accurate cutting is possible without the risk of the cut surface becoming wavy or rough.

When the object to be processed is positioned at a predetermined position on the table, the corners of the table are brought into contact with stoppers provided on the sizer blade support base to perform positioning. Since both ends of the portion that serves as a reference for positioning the object are positioned by the stoppers, highly accurate and efficient positioning can be performed.

Further, since the stopper attached to the sizer blade support moves integrally with the sizer blade support along the peripheral side surface of the table, it is easy to deal with various changes in the size of the object to be processed. it can.

The pin 48 for positioning the object to be processed is at the base end side thereof. Is operated by an air cylinder 80 attached thereto, and the stopper 32 is operated by an air cylinder 82 attached thereto and a link mechanism connected thereto. As described above, the processing object positioning pin 48 and the stopper 32 are configured to be movable back and forth, respectively, when the processing object W is cut by the horizontal sizer blade 14 while moving the motor base 66. , The object positioning pin 48 and the stopper 32
Is to prevent the workpiece W from hitting the workpiece W, and to advance the workpiece positioning pin 48 and project the stopper 32 only when necessary.

Further, as shown in FIG. 11, the first horizontal end stopper 31 and the vertical end stopper 46 attached to the corners of the table frame 25 are also individually provided in the air cylinder and continuously provided thereto. The link mechanism (both not shown) is operated so that the stoppers 31 and 46 do not interfere with the horizontal sizer blade 14, the vertical sizer blade 13 and the motor bases 50 and 66 during cutting.

Further, the first sizer 3 is provided with a measuring means 100 for measuring the vertical and horizontal dimensions of the object W to be processed. The measuring means 100 is divided into a vertical dimension measuring means 100a for measuring the vertical dimension of the workpiece W and a lateral dimension measuring means 100b for measuring the horizontal dimension of the workpiece W.

The vertical dimension measuring means 100a includes limit switches 102 at predetermined intervals along the guide rail 68.
... are provided, and the motor base 66 is brought into contact with the operators of the limit switches 102 so that the limit switches 1
A switch operation plate 104 for turning on / off 02 is attached.

In the vertical dimension measuring means 100a, the motor base 66 moves in the Y2 direction when the workpiece W is positioned in the vertical direction in the pre-cutting stage, and the workpiece is positioned in the protruding state. When the workpiece W is pressed by the pin 48 and comes into contact with the vertical end stopper 46, it is determined which limit switch 102 is pressed by the switch operation plate 104, and based on this, the vertical length of the workpiece W is determined. Measure the dimensions.

On the other hand, the lateral dimension measuring means 100b is provided at the front end portion of the table 6 which overlaps with the end portion of the transfer ruler 30 at predetermined intervals along the axial direction of the transport roller 11 by the limit switches 108. ... is provided,
These limit switches 10 are provided at the end of the transfer ruler 30.
A switch operation plate that comes into contact with the operator of No. 8 and turns on / off the limit switch 108 is attached.

In this vertical dimension measuring means 100b, when the transfer ruler 30 moves in the X1 direction to position the object to be processed W before the cutting, the object W to be processed is divided into the first and second lateral directions. When contacting the end stoppers 31, 32, it is determined which limit switch 108 has been pressed, and the lateral dimension of the workpiece W is measured based on this.

Limit switches 114, 116 and 118 are provided at both ends and an intermediate portion of the motor base 50 in the guide rail 60 for guiding the motor base 50 for supporting the vertical sizer blade. ing. The limit switch 114 on the base end side is the motor base 5
0 is for determining whether or not 0 exists at the base end position, and the central limit switch 116 is the motor base 50.
Is moving and is cutting the workpiece W, more specifically, for determining whether or not the motor base 50 has reached the intersection position with another motor base 66. is there. Further, the limit switch 118 is for determining whether or not the motor base 50 has reached the tip in the moving direction, and reverses the moving direction of the motor base 50. Reference numeral 122 is a limit switch for reversing the moving direction of the motor base 66 that supports the horizontal sizer blade 14.

When the side end surface and the rear end surface of the workpiece W are cut by the vertical and horizontal sizer blades 13 and 14 while moving the motor bases 50 and 66, respectively, the motor bases 50 and 66 interfere with each other. However, here, the motor base 50 on the vertical sizer blade 13 side
Is adjusted by giving priority to.

That is, when the limit switch 116 is turned on and it is detected that the motor base 50 has passed the substantially central portion of the guide rail 60 (the position where the motor bases 50 and 66 intersect each other), the horizontal sizer blade is used. Even when the motor base 66 to which 14 is attached is moving in the Y2 direction, the motor base 66 is detected by the stop limit switch 112 provided at the intermediate portion of the guide rail 68, as shown in FIG. The vehicle is stopped at that position (standby position immediately before the crossing position) as shown in. After the cutting by the vertical sizer blade 13 is finished and the motor base 50 moves in the X2 direction and the limit switch 116 is turned on again, the stop of the horizontal sizer blade 14 is released, and the horizontal sizer blade 14 becomes the motor base 66. It moves in the Y2 direction as a unit and cutting is performed. An optical sensor 120 is arranged substantially at the center of the front end of the table 6 so that whether or not the object W to be processed is present on the table 6 can be determined.

On the other hand, the second sizer machine 4 has a so-called point-symmetrical arrangement structure in which it is rotated 180 degrees with respect to the first sizer machine 3 as described above. The second sizer machine 4 has a table 7 for transporting and fixing the workpiece W, a flip-up type transport path 10, and a transport roller 11a provided at the front end of the table 7. Is vertically movable, has a positioning means 26 for positioning the workpiece W at a predetermined position on the table 7, and has a fixing means for fixing the workpiece W fixed at a predetermined position. Most of the components are common to the first sizer machine 3, such as having 28 and having the vertical sizer blade 13 and the horizontal sizer blade 14.

However, the difference is that the movement of the motor bases 50 and 66 is performed based on a command from the computer 130. That is, in the first sizer machine 3, since the vertical and horizontal dimensions of the object to be processed W are measured before the cutting process, the dimension of the object to be processed W at the time of being loaded into the second sizer machine 4 is not. I know in advance. Therefore,
When the motor base 66 moves in the Y1 direction for positioning and cutting, it moves at a high speed until just before the positioning pin 48 contacts the workpiece W, and thereafter at a predetermined speed suitable for cutting and pressing transfer. It is designed to move. In addition, the motor base 5 supporting the vertical sizer blade 13
The same applies to 0, and the motor base 50 is used for disconnection.
When moving in the X2 direction, the sizer blade 13 moves at a high speed until just before the sizer blade 13 comes into contact with the workpiece W, and then moves at a predetermined speed suitable for cutting.

As described above, the sizer device 2 is provided with the computer 130. In addition to the moving speeds of the motor bases 50 and 66 of the second sizer device 4 described above, the machines constituting the sizer device 2 are also provided. Each action is performed by associating physical elements with each other. The specific configuration will be clarified in the operation description below,
Detailed description is omitted here.

Next, the operation of the sizer device will be described. A panel-shaped object W having face materials joined to both surfaces of a core material is transferred by a pressing machine (not shown) on the transport path 1 and is flipped up in a horizontal state in advance to be a flip-up transport path 1.
0, and is transferred to the table 6 of the first sizer machine 3 (see FIG. 5).

On the table 6, the workpiece W is transported in the forward direction by the transport rollers 11, and when the rear end of the workpiece W passes the rear end of the table 6, the fact is provided at the rear end of the table 6. The transport roller 11 is temporarily stopped after being detected by the optical sensor 120, and then reversely rotated for an extremely short time. As a result, the workpiece W is stopped at a position where its rear end substantially coincides with the rear end of the table 6 (see FIG. 4). When the transport roller 11 is rotated in the reverse direction, the roller 11a at the rear end is raised so that the workpiece W is slightly floated.

Then, a motor (not shown) rotates, and the flip-up type conveyance path 10 rotates about the support shaft 18 to be in an upright state (see FIG. 11). Then, the workpiece W is positioned at a predetermined position on the table 6 by the positioning means 26. Specifically, the air cylinder is operated and the table 6
The first lateral end stoppers 31 and the vertical end stoppers 46 provided at the corners of the table 6 are arranged at positions projecting above the upper surface of the table 6 and engaged with the workpiece W on the table 6. It is in the possible position and the cylinder is actuated to bring the positioning pin 48 into the extended state.

At approximately the same time, the pulse motor 70 is driven as shown in FIG. 6, and the motor base 66 supporting the lateral sizer blade 14 is moved in the Y2 direction via a power transmission system such as a chain. The movement of the motor base 66 is performed at high speed in the initial state, but is performed at low speed after the presence of the workpiece W is detected by the optical sensor 72 provided at the side edge portion of the motor base 66. Further, in this way, the motor base 66 is switched to a low speed during the movement, and the cylinder 82 is operated so that the second lateral end stopper 32 projects laterally from the motor base 66.

Along with the movement of the motor base 66, a motor (not shown) is driven to rotate the bolt member 38 in a predetermined direction, and the transfer ruler 30 is moved in the X1 direction in the drawing. At this time, the side end surface 30a of the transfer ruler 30 comes into contact with the side edge of the opposite workpiece W, and the workpiece W is moved in the same direction. The front and rear end surfaces of the workpiece W are first and second
By abutting the lateral end stoppers 31 and 32 of, the lateral positioning is performed. Similarly to the movement of the motor base 66, when the transfer ruler 30 constituting the positioning means is moved in the X1 direction, the transfer ruler 30 is moved at a high speed in the initial stage of the movement and is switched to a low speed immediately before reaching the final positioning position. Good. As the speed switching means, for example,
There is a method in which a sensor is provided in the vicinity of the first lateral stopper 31 and the speed of the transfer ruler 30 is switched to a low speed when the sensor measures an object to be processed.

On the other hand, as described above, the first lateral end stopper 31 in the protruding state and the second lateral end stopper 32 in the overhanging state, and the transfer ruler 3 moving in the X1 direction.
The object to be processed W is generally sandwiched between 0 and 0, and in this state,
Further, the motor base 66 further moves in the Y2 direction.
As a result, the positioning pin 48 in the projecting state pushes and moves the end portion of the workpiece W, and brings the workpiece W into contact with the vertical end stopper 46. As a result, the workpiece W is positioned in the vertical direction (see FIG. 7).

Next, a clamp 40 which is the fixing means 28.
The workpiece W thus positioned is fixed at that position. Specifically, the air cylinders attached to the upper frames 52, 54 are actuated, and the object W to be processed is provided between the engaging portion attached to the tip of the descending piston rod and the end plate of the lower table frame 25. Insert it firmly. At this time, the rear end surface and the side end surface, which are the cut portions of the object to be processed W, project slightly outward from the edge surface of the table frame 25.

At the time when the fixing of the object W to be processed is completed,
After the first horizontal end stopper 31 and the vertical end stopper 46 are lowered, and the motor base 66 is slightly moved in the Y1 direction, the second horizontal end stopper 32 and the workpiece positioning pin 48 are rearward. Retreat to.

Next, the motor base 5 is driven by the driving means.
0 is moved in the X1 direction, the rear end surface of the workpiece W is cut by the vertical sizer blade 13 attached to the upper part thereof, and the motor base 66 on the other side is further moved in the Y2 direction along with it. The lateral sizer blade 14 attached to the upper portion cuts the side end surface of the workpiece W.

The object W to be processed is cut by the vertical sizer blade 13 described above.
When the trailing end is sizer processed, that is, when the limit switch 116 located at the intermediate position of the guide rail 60 detects that the motor base 50 has passed the position, the motor base 66 moving in the Y2 direction is detected.
Is stopped at that position as it passes the limit switch 112. In this way, by moving the vertical sizer blade 13 preferentially, it is possible to avoid the interference between the vertical sizer blade 13 and the horizontal sizer blade 14 (see FIG. 9).

When the cutting by the vertical sizer blade 13 is completed and the motor base 50 reaches the movement limit position in the X2 direction, the limit switch 114 detects that fact, and the interruption of machining by the horizontal sizer blade 14 is released. . That is, the motor base 66 moves again in the Y2 direction, and cutting is performed by the horizontal sizer blade 14 (see FIG. 10).

When the above cutting is completed, both sizers 1
Both 3 and 14 return to their original positions and stop. At the same time, the flip-up type transport path 10 is also tilted to its original horizontal state (see FIG. 3). Then, a motor (not shown) is driven to rotate the bolt member 38 in the opposite direction to the above, and the transfer ruler 30 is moved in the X2 direction. At this time, the workpiece W is gripped by the clamp 40 attached to the transfer ruler 30 in advance, and therefore, the workpiece W is moved in the X2 direction together with the transfer ruler 30 and the table 6 is moved. Is returned to the center position in the width direction of.

Then, the transport roller 11a at the rear end of the table 6 is lifted to move the workpiece W to the table frame 25.
A little above the other transfer roller 11 in this state.
At the same time, the transport rollers 11 rotate in a predetermined direction to transport the workpiece W forward. Here, the reason why the workpiece W is slightly floated from the table frame 25 as described above is to reduce the frictional force at the initial stage of the transport and realize the smooth transport. It should be noted that, after the conveyance by the conveyance roller 11 is started,
Immediately descends to its original position.

Then, the workpiece W processed as described above is transferred to the second sizer machine 4. Here, substantially the same operation as that performed by the first sizer machine is performed, and the front end face, which is the unprocessed portion of the workpiece W, and the other side end face are each cut.

That is, the workpiece W is first positioned by the transport roller 11 so that its front end is substantially aligned with the front end of the table 7, and the workpiece W is further positioned by the positioning means 26 at a predetermined position on the table 7. After being accurately positioned, it is fixed by the fixing means 28 and cut by the vertical sizer blade 13 and the horizontal sizer blade 14, respectively.

Here, in the vertical positioning of the workpiece W in the second sizer 4, the positioning pin 48 that moves integrally with the motor base 66 contacts the workpiece W, and the table 7 is moved. Vertical end stopper 46 provided on
It is performed by pressing and moving the object W until it hits. In addition, the horizontal positioning is performed by the transfer ruler 30.
Moves in the X1 direction and stops on the table 3
It is performed by pressing and moving the object W until it hits the object 1, 32.

At this time, the vertical and horizontal dimensions of the object W to be processed have been measured in advance by the measuring means 100 in the first sizer machine 3, and therefore the object W to be processed is positioned in the second sizer machine 4. The position of the positioning pin 48, that is, the position of the motor base 66 to which the pin 48 is attached is known in advance, and the position of the transfer ruler 30 is also known in advance.

Therefore, by determining whether or not the actual position of the motor base 66 or the position of the transfer ruler 30 at the time of positioning matches the calculated value,
It is possible to judge whether or not the positioning of the workpiece W is performed as desired. If it is determined that the workpiece W is not positioned as desired, it may be indicated by a blinking lamp, a buzzer, or other display means, or the line may be stopped, if necessary. Therefore, it is possible to prevent further wasteful processing of defective products.

When the second sizer 4 is used for cutting, the motor base 50 is moved in the X2 direction and the other motor base 66 is moved in the Y1 direction. Since the dimensions are measured in advance during the processing by the first sizer machine 3, until just before the positioning pin 48 contacts the workpiece W,
Alternatively, the motor bases 50 and 66 are moved at a high speed until just before the vertical sizer blade 13 comes into contact with the workpiece W, and thereafter, the motor bases 50 and 66 are moved at a predetermined speed suitable for cutting or pressing transfer.

As described above, by changing the moving speeds of the motor bases 50 and 66 on the way, it is possible to perform a good cutting process, and it is possible to eliminate the waste of the moving time of the vertical sizer blade 13 and the horizontal sizer blade 14. The cutting efficiency can be improved. And when the above sizer processing is completed,
When the transfer ruler 30 is returned to its original position, the transfer ruler 3
The workpiece to be processed is also returned to the substantially central portion in the width direction of the table 7 by the clamp 40 attached to the front end of the transport roller 1
1a rises to a state in which it slightly floats from the table frame, and the transport roller 11 is driven to feed the processed object forward.

The above operation is a series of steps for performing sizer processing on the object to be processed. Hereinafter, by repeating the above steps, the conveyed object W to be processed can be continuously subjected to sizer processing. It should be noted that even during processing by the second sizer machine 4, simultaneous processing by the first sizer machine 3 can be performed.

The sizer of the present invention is not limited to that shown in the above-mentioned embodiment, but the specific components such as the shape, dimensions, work procedure, etc. of each member can be appropriately changed in practice.

For example, in the above-described embodiment, the transfer ruler 30 is used as the transfer means for laterally transferring the object to be processed, and the ruler 30 is transferred by the screwing means of the bolt member 38 and the nut 36. However, the present invention is not limited to this, and a configuration in which an object to be processed may be directly pressed by an air cylinder or a hydraulic cylinder may be adopted. Further, as the sizer blade, as long as the side end surface of the wooden panel can be sizer processed, it is possible to use other than the circular cono shaped one shown in the above embodiment, and a drive for driving this. The device is not limited to the one shown in the above embodiment.

[0070]

As described above, according to the sizer device of the present invention, the object to be processed is temporarily fixed on the table and cut, so that good cutting can be performed and the cut surface is wavy or rough. High-precision cutting is possible without the risk of being stuck. Moreover, when positioning the object to be processed at a predetermined location on the table, the corners of the table and the stoppers provided on the sizer blade support are brought into contact with each other to perform positioning. Since both ends of the part that becomes the reference of are positioned by stoppers,
Positioning can be performed with high accuracy and efficiency. Further, since the stopper attached to the sizer blade support moves integrally with the sizer blade support along the peripheral side surface of the table, it is possible to easily deal with the case where the size of the object to be processed changes. It has an excellent effect.
