Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic edge processing system for doors such as kitchen cabinets.

[0002]

2. Description of the Related Art In general, doors for kitchen cabinets and other furniture have a decorative sheet attached to their surface,
An edge material is attached to the mouth of the tree, which is what is called a banding process for commercialization. Since the door has a rectangular shape, the wood entrance has four sides, and the edge material is banded individually.

A conventional door edge automatic processing system will be described below with reference to FIG. In the figure, 31 is a roller conveyor, 32 is an automatic feeder, 33 is a tenor, 3
4 is a material turning device, 35 is a tenor, 36 is an edge bander, 37 is a pick-up lifter, 38 is an NC borer, 39 is an NC router, 40 is a roller conveyor, 4
Reference numeral 1 denotes a hot melt adhesive coating machine 42, which is an automatic ornament attachment machine, and these constituent elements are sequentially connected to form one automatic manufacturing line. Then, by mounting a door (not shown) on the roller conveyor 31, the doors are sequentially fed, and the edge bander 36 automatically performs the banding processing of the door end of the door, and thereafter, processing such as decorative attachment is appropriately performed. It is supposed to be given.

[0004]

By the way, in the conventional door edge automatic processing system, since the edge bander 36 performs the banding process on one side of the door, it is necessary to perform the banding process on all four sides of the door. , The worker has to take out the door and set it again on the edge bander 36 each time the banding process on one side is completed, that is, the setting work must be performed at least three times, so the workability is poor, and It cannot be fully automated. Furthermore, the flow stops at the edge bander 36, and efficient processing cannot be performed.

The present invention has been made in consideration of the above-mentioned conventional problems, and an object of the present invention is to provide an automatic processing system capable of continuously and automatically performing edge banding processing on the entrances of four sides of a door.

[0006]

In order to achieve the above object, an automatic door edge processing system of the present invention has an edge bander in an automatic door processing line, and the edge bander is provided in a stage before the edge bander and in a stage before the edge bander. A feedback feed path is provided to reach the feedback feed path, and the feedback feed path has means for changing the direction of the door.

[0007]

In the above structure, the door reaches the edge bander, and the required edge banding process is automatically performed on one side of the entrance, and the direction is changed from the latter stage of the edge bander to the front stage of the edge bander by the feedback route. Then, the edge banding processing of the unprocessed side edge is automatically performed again and is sent out.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In the figure, 1 is a roller conveyor, 2 is an automatic feeder, 3 is a tenor, 4 is a material turning device, 5 is a tenor, 6 is an ejecting device, 7 is a pick-up lifter, and 8
Is a single type edge bander, 9 is a pick-up lifter, 10 is a moving lifter, 11 is a direction changing device, 12 is an NC borer, 13 is an NC router, 14 is a roller conveyor, 15 is a hot melt adhesive applicator, 16 is An automatic pressing press, 17 is a hot melt adhesive coating machine, 18 is an automatic decoration mounting machine, and 19 is a workbench, and these respective components are sequentially connected to form a work line.

The feature of this embodiment lies in the configuration described below.
That is, the movable lifter 20 is provided in front of the edge bander 8.
And a first material turn device 21 is provided at the subsequent stage of the edge bander 8, and a belt conveyor 22, a second material, and a third material connected in series from the first material turn device 21 at the subsequent stage. The feedback path 26 including the turn devices 23 and 24 and the moving lifter 25 is connected to the preceding moving lifter 20.

The first material turning device 21 is provided with a projecting device 27. In the figure, 28 is a decorative attachment machine, and 29 is a round trimming machine. In the above structure, by mounting a door (not shown) on the roller conveyor 1, the doors are sequentially fed, and the edge bander 8 performs edge banding processing on the mouth of the door.
After that, it is the same as the above-mentioned conventional example that processing such as decorative attachment is appropriately performed.

However, the door that has been edge-banded at one side of the edge bander 8 is changed in direction by 90 ° in the first material turn device 21 in the subsequent stage, and the second and third doors in the feedback feed path 26 are changed. The material is sent to the material turning devices 23 and 24 of the edge bander 8 and is also changed in direction there, and is returned to the moving lifter 20 in the preceding stage of the edge bander 8 and again in the edge bander 8. Edge banding processing of. By feeding the door three times through this feedback feed path 26 and processing it by the edge bander 8, the edges of all four sides of the door are edge-banded. In addition,
If the edge banding process for the door requires only three sides, the feedback feed path 26 sends the door twice.

As described above, in this embodiment, by providing the feedback path 26 from the rear stage of the edge bander 8 to the front stage of the edge bander 8, the door is returned to the edge bander 8 a required number of times and each side is returned. Since the edge banding process of the wood mouth can be automatically performed, it is not necessary for the worker to pick up and reset the door as in the conventional case, and the workability is improved.

It is to be noted that the door is connected to the feedback passage 26 described above.
Whether or not to send to the door is determined by a counter or a sensor, and when the banding process for all the door openings of the door is completed, the ejecting device 27 operates and the door is sent to the working unit in the subsequent stage. Further, in the present embodiment, the movable lifter 20 is arranged so that the door is placed at two positions, and the door can be stocked at one position.

The work lines before and after the edge bander 8 are not limited to those in the illustrated embodiment.

[0015]

As is clear from the description of the above embodiment,
The door edge automatic processing system of the present invention can continuously perform the edge automatic processing of each side of the door, and the operator does not need to reset the door for each edge banding process of the mouth of one side of the door. The work can be done very efficiently, which contributes to the reduction of production cost.
