Description

Detailed Description of the Invention "Field of Industrial Application" The present invention is an automatic processing method that simultaneously performs drilling at any position on the end surface of a wooden member for furniture and mounting of joint parts while continuing to move the member. It is related to the device.

``Prior Art'' Conventionally, as shown in Fig. 6, machines for drilling holes and attaching parts to the end surface of wooden furniture members include a drilling station (a) and an adhesive application station. (b) and a joining parts insertion station (C) are provided, and when processing one member, the feeding of the member is stopped after each processing step.

[Problems to be solved by the invention] As mentioned above, in the past, three steps were required to process a single piece of furniture, which resulted in long processing times, poor productivity, and damage to the furniture itself. When processing wide parts such as the side panels and top plates of a machine, it is necessary to build a very long machine, and conventional machines have the problem that they can only process narrow parts such as parts of extraction boxes. Ta.

The present invention combines the drilling process and the joining part insertion process with a reciprocating mechanism without stopping the conveyance of the part, thereby improving productivity regardless of the width of the part. The purpose of this is to make it possible to respond to high-mix, low-volume production in response to users' individualization preferences by making it possible to freely adjust processing dimensions.

"Means for Solving the Problem" In the present invention, the three tool axes for drilling holes, applying adhesive cloth, and inserting parts to be joined are made movable as one unit, and reciprocate without stopping the feeding of the parts. These three processes are performed at the same time.

That is, to explain with the drawings, the automatic processing apparatus according to the present invention is as shown in FIGS. 1 and 2.

They are disposed opposite to each other on both sides of the conveyance mechanism, and (2) is a caterpillar with dogs provided at appropriate locations, and is driven by a servo motor 2. 3 is a gear hook having a cone shaft 3a, and air rings 4, 4 for cone shaft selection, and a cone shaft 3 in parallel thereto.
A spindle motor 5 is connected to drive the gearbox a, and an advance cylinder 6 for advancing the gear box is provided at the rear to constitute a pilot hole drilling unit I. Further, a sliding cylinder 10 is connected to a dowel insertion head 9 of a joining component which has an insertion hammer shaft 7 and a hammer cylinder 8 in parallel with this pilot hole processing unit to constitute a component insertion processing unit. Then, both of them are placed on a sliding table 12 that is moved by a servo motor 11. Do 1.

The slide table 12 is further slidably mounted on a slide table 13 and is screwed onto a pawl screw 16 which is rotated by a servo motor 14 via a transmission 15. The drive of each servo motor 11, 14 is automatically operated by numerical control.

"Function" Wooden processing parts such as furniture carried in and placed on the caterpillar l are positioned according to the width size, and then driven by the servo motor 2 and transported, and moved without stopping. Continue. During this time, the processing unit also moves the slide table 121z by the servo motor 11 in synchronization with the movement of the member.

This moving machining member is drilled in the end surface by a drilling drill at the position of the machining unit that moves synchronously. The drilling awl is formed or attached to the tip of a conical shaft 3a that is rotated by a spindle motor 5 in a gear box 3, and the forward movement of the conical shaft 3a is performed by a forward cylinder 6. Further, several cone shafts 3a are provided, and a desired cone can be selected and machined using a cone shaft selection cylinder 4 connected to each cone shaft 3a.

When the drilling process is completed, the drilled workpiece continues to be fed and moved, but the conical shaft 3a is moved in the opposite direction on the slide table 12 by the servo motor 11, and the part insertion processing unit meets the drilled part. Then, while moving in synchronization with the feed movement of the member again, insert the redapo into the slide cylinder 10 S! Put jli9 on the hole,
The insertion hammer shaft 7 is actuated by the hammer cylinder 8 to insert and process the fed dowel.

Each time a member is fed into the processing unit, the above operations are repeated to automatically perform processing. Incidentally, the processing units on both sides are positioned and adjusted by sliding the sliding body 12 on the sliding body 13 by a pole screw 16 which is rotated by a servo motor 14.

Further, the distance between the prepared hole machining unit and the component insertion unit may be changed as appropriate on the sliding body 12, so that the ff& material can be made to correspond to the machining position.

It goes without saying that the insertion hammer shaft 7 for inserting one component can also be selected as a plurality of shafts according to the required dimensions, and that it can be made to correspond to the dimensions of the member along with the selection of the drilling shaft.
