DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a frame member for doors and closets by processing an end of a workpiece such as wood.

[0002]

2. Description of the Related Art Generally, doors and closets are attached to a building via a frame. These frames are formed by assembling a vertical frame and a horizontal frame, which are frame members, into a rectangular or gate shape. FIG. 4 shows an example of the horizontal frame 5. In general, the frame members, including the vertical members, are provided with predetermined processing (such as unevenness 5a and holes 5b) at both ends like the horizontal frame 5. In order to produce a frame member by performing such processing on both ends of wood, a processing machine such as a kiguchi boring machine, a kiguchi chipping cutter machine, or a kiguchi router boring machine controlled by NC is usually used.

The frame member has a width of about 200 mm.
mm or less, but the length is significantly different for, for example, doors and closets. That is, the short one for the door is 600
mm, whereas a long one for a closet is about 3800 mm.

Therefore, in order to fabricate a frame member by processing both ends of the above-mentioned wood, conventionally, two types of different processing apparatuses have been used according to the length thereof. That is, for wood for doors whose length is relatively short and the range is almost constant, a processing machine having a plurality of processing machines such as a router machine arranged at both ends thereof is used. The parts were processed at the same time, and the wood was conveyed laterally by a belt conveyor or the like, so that different processing was performed one after another by another processing machine.

On the other hand, for extremely long wood for a closet, such a processing device cannot be used because the length is too long. Therefore, a processing device that transports wood in a vertical direction by a conveyor and processes both ends is used. That is, a processing machine such as a router machine is arranged at each of the front and rear ends of the conveyor, and the rear end processing machine first processes the rear end of the wood, and when this is completed, the wood is transported to the front end side and the front end processing machine is processed. After aligning the front end of the wood, the front end was processed.

[0006]

However, in the above-mentioned conventional processing apparatus, a clamp for fixing the wood on a conveyor when processing the end of the wood is provided at the rear side of the processing machine. Had been attached to the pole. Here, the support is installed on the rear side of the processing machine in order to prevent an obstacle when the wood is transported in the lateral direction of the processing machine. As a result, a long arm was provided from the column to the place where the timber was fixed. For this reason, the clamp became large as a whole and hindered the work.

The present invention has been made in view of such circumstances, and an object of the present invention is to reduce the size of a clamp for fixing a workpiece such as wood as a whole so that the clamp does not hinder the work. An object of the present invention is to provide an apparatus for manufacturing a frame member.

[0008]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an apparatus for manufacturing a frame member for manufacturing a frame member by processing an end of the workpiece. A processing machine for processing the end is disposed on one side of the conveyor to be conveyed, and a clamp for fixing the workpiece on the conveyor is supported on a column of the processing machine. With this configuration, the clamp can be downsized as a whole.

According to a second aspect of the present invention, in addition to the first aspect, the clamp is provided with an arm portion and a pressing portion, and the arm portion is fixed to the column and the pressing portion is provided on the column. The pressing portion is provided with a contact member that moves downward.

[0010] Here, the arm portion is composed of two parallel vertical members and two orthogonal vertical members.
And a horizontal member on the rear side of the horizontal member is fixed to the column, a pressing portion is provided on the front horizontal member, and the pressing portion extends along the front horizontal member. Preferably, the horizontal member on the front side is movable along the vertical member.

With this configuration, the workpiece is pressed onto the conveyor by the contact member, and is thereby fixed. In addition, since the pressing portion can move back and forth and left and right with respect to the column, when the workpiece is fixed on the conveyor by the abutting member, it does not move with respect to the conveyor even if the column moves forward and backward and left and right. Becomes

Then, the sheet P is conveyed in the horizontal direction by the conveyance pins 41 and reaches the front surface of a second processing machine (for example, a cutting machine having a cut-off edge) 32. And clamp 6
Is fixed on the conveyor 11.

Then, the end 21 is processed by the second processing machine 32 in the same manner as in the case of the first processing machine 31. Thereafter, the above steps are repeated for the third processing machine (for example, a kiguchi router boring machine) 33.

When the processing by the third processing machine 33 is completed in this way, the two pieces of wood 2 are transported onto the third conveyor 13 by the transport pins 41 while maintaining a constant interval. Then, after being transferred in the vertical direction, it is transferred onto the second conveyor 12.

Then, similarly to the case of the first conveyer 11, the conveyer is conveyed in the lateral direction by the convey pins, stoppers and pushers provided on the second conveyer 12, and further,
It is transported vertically by a vertical transport device. Then, it is fixed on the conveyor 12 by the clamp, and the front end is processed by the fourth, fifth, and sixth processing machines 34, 35, 36.

Therefore, according to the manufacturing apparatus 1, the clamps 6 are supported by the columns 3c of the processing machines 31, 32, 33, 34, 35, and 36, respectively. When transporting 2 in the horizontal direction, the clamp 6 does not become an obstacle.

Further, since the pressing portion 64 can be moved back and forth and left and right with respect to the column 3c, even if the column 3c is moved back and forth and left and right when processing the wood 2, the contact member 64a is immovable with respect to the conveyor 11. can do.

Further, while the timber 2 is fixed on the conveyor 11, the arm 60 moves together with the column 3c of the processing machine 31, so that the fixing position of the timber 2 by the contact member 64a is always optimal for the processing shape. Position.

That is, when the processing location at the end portion 21 is slightly closer to the center of the wood 2, the processing machine 31 is advanced to perform the processing, so that the position slightly closer to the center can be fixed. In addition, when the processing location at the end 21 is limited to the vicinity of the opening, the processing is performed by retracting the processing machine 31, so that a position close to the opening can be fixed. Therefore, the fixed position of the wood 2 is always at the optimum distance from the processing place, so that stable processing can be performed.

The present invention is not limited to the above embodiment. For example, in addition to wood,
A material similar to wood, such as MDF made by hardening sawdust, or plastic may be used.
