Description

[Detailed Description of the Invention] (Object of the Invention) The present invention is capable of processing long pieces of wood that protrude from the surface plate, once placed on the surface plate, without having to change the placement. This paper relates to an automatically traveling silver plate whose purpose is to improve processing efficiency.

(Prior art) In the conventional automatic traveling silver plate, the entire silver plate ran parallel to the surface plate to process the workpiece wood placed on the surface plate, so the surface plate was longer than the length of the surface plate. In the case of a long piece of wood that protrudes from the wood, it is first processed within the processable range, then the direction of the piece of wood is reversed and the unprocessed portion is processed.

Therefore, as the heavy wood to be processed is changed from being placed on the surface plate during processing, the fatigue of the worker increases, and since continuous processing cannot be performed, a decrease in processing efficiency is unavoidable.

(Structure of the Invention) The basic structure of the present invention is to provide a silver plate body which has a surface plate on which the wood to be processed is placed and can freely move back and forth in the length direction of the surface plate, and which can be moved up and down on the silver plate body. In an automatic running silver plate, which is equipped with a cutter rest, and a rotary cutter driven by an electric motor on the cutter rest, both lengthwise ends of the surface plate are opened,
A fixing device is provided on the surface plate to clamp and fix the wood to be processed placed on the surface plate from both sides while the silver disk body is running, and to release the fixation after the silver disk body has stopped running, and an electric motor installed on the tool rest. A feed roller is provided on the tool post in parallel with the rotary cutter, and the feed roller is capable of intermittent power transmission and to which the power is transmitted after the silver plate body stops running, and the feed roller is attached to the workpiece wood placed on the surface plate. It is provided so that it can be pressed.

Then, when the wood to be processed is placed on the surface plate, the wood to be processed is fixed on the surface plate with a fixing device, and the silver disk body is run while the rotary cutter is rotated, while the silver disk body is running, The wood to be processed is cut.

When the main body of the silver plate travels at a predetermined position and stops, the fixing of the wood to be processed by the fixing device is released, power is further transmitted to the feed roller, which starts rotating, and the wood to be processed, pressed by the feed roller, is transferred to the surface plate. The top is moved in the opposite direction to the running direction of the silver disc body.

By continuing to cut with the rotary knife during the movement, it is possible to cut long pieces of wood that would otherwise be impossible to cut within the travel range of the silver disc body.

Embodiments of the present invention will be described below based on the drawings.

In addition, a gate-shaped or cantilever-shaped well-known mortise cutter or corner milling machine is installed on both left and right ends of the surface plate 1, and the planed workpiece wood W is sent in the longitudinal direction on the surface plate 1. It may also be possible to perform continuous operations such as tenon removal and square hole spacing.

(Operation of the Invention) To explain the present invention in detail, the silver plate main body 5 is placed on the surface plate 1 in advance.
, and place the wood W to be processed on the surface plate 1.

When the workpiece wood W is long and protrudes from the surface plate 1, the right end W
' is positioned so as to protrude from the surface plate 1, and the button air cylinder 4 is operated to clamp and fix the wood W to be processed between it and the stopper 3.

In this state, position the tool rest 8 at the required height and
8 at high speed in the direction of arrow P, and the exhaust fan 42
is activated to collect the planer chips, and furthermore, the electric motor 32 is started to move the silver plate main body 5 to the right at a constant speed by driving the wire rope 30, and processing is performed using the rotary blade 18.

At this time, since the electromagnetic clutch 23 is not magnetically attached, it rotates idly while pressing the wood W to be processed.

When the silver disc main body 5 finishes moving to the right on the guide rail 7.7, it stops moving at that position, is immediately released from being fixed by the air cylinder 4, and at the same time the electromagnetic clutch 23 of the tool rest 8 is released.
operates, and the feed roller 20 and chain wheel 24 are connected together, and the electric motor 25 is started, and the feed rollers 20, 20, which had been idling in the past, begin to rotate in the direction of arrow Q, and rotate in a pressed state. This moves the wood W to be processed to the left.

The workpiece wood W is placed on the surface plate 1 with rollers 2, 2, etc.
Since it is placed on ..., it is easily moved to the left, and processing is continued by the continuously rotating rotary cutter 18, with the left end W〃' of the wood to be processed protruding from the surface plate 1. 1, and the processing of the upper surface of the wood W to be processed is completed.

If you want to continue processing the lower surface and both left and right sides of the wood W to be processed, move the silver plate body 5 to the left again and position it at the starting point, and turn over the wood W to be processed so that the other processing surfaces face upward. Processing is performed.

Even if the silver disk main body 5 is equipped with a saw or a super-finishing silver disk, the workpiece wood W can be fixed on the surface plate 1 and the silver disk main body 5 is moved to the right when cutting the workable wood W. Processing is performed, and at the end of the movement of the silver disc main body 5, the fixation of the wood W to be processed is released, and the feed rollers 20, 20 are activated, and the wood W to be processed is moved to the left by the feed rollers 20, 20, and the wood W to be processed is split. Or perform super finishing plane processing.

When processing with a tenon cutter or a corner chisel installed on both ends of the surface plate 1, move the wood W to be processed on the surface plate 1 to the required position using feed rollers 20° 20 or by hand. processing.

Since the overhead wire 35 is stretched between the support column 34 and the right end of the surface plate 1, it is always stretched with a constant tension even while the silver disc main body 5 is running, and does not loosen.

(Effects of the Invention) The present invention opens both left and right ends of the surface plate, provides a large number of rollers on the surface plate, and provides a feed roller on the main body of the silver plate, which has a surface plate and can move freely from side to side. Since the wood to be processed is pressed and moved freely from side to side, the wood that is long enough to rest on the surface plate can be moved, and even the wood that is long enough to protrude from the top of the surface plate can be easily moved. Continuous processing is possible without having to reload processed wood on the surface plate, improving processing efficiency, and eliminating the need to reload heavy processed wood reduces worker fatigue, streamlining work and saving labor. becomes possible.

In addition, in the case of long pieces of wood to be processed, unlike conventional machines that only move the wood to be processed, a large factory space is not required, and there is a slight margin at both ends of the surface plate for the wood to be processed to protrude. Factory space can be used effectively.

In the case of ordinary short pieces of wood to be processed, processing by moving the wood to be processed and processing by fixing the wood to be processed can be conveniently selected depending on the material of the wood to be processed, the accuracy of processing dimensions, etc.

Furthermore, by providing a tenon cutter or a corner chisel at both ends of the surface plate, processing can be performed in a line, and processing efficiency is improved regardless of whether the wood to be processed is long or short.
