2. Description of the Prior Art Accurate hooking work performed at sawmills and woodworks is performed by a carpenter who is an excellent technician until a long time ago, and is extremely efficient and finishes a smooth surface with a wonderful finish. It was possible to recruit as many workers as possible, but nowadays, not only the number of technicians with such highly skilled hooking techniques is extremely small, but also the hooking technique is learned. Since almost no one is willing to try it, an automatic plane-hanging device that can efficiently hang a large number of timber at the same time was introduced at some time, and due to its convenience, it is now available. Not only is it used in specialized manufacturing industries such as sawmills and woodworks, but it is also being installed in work corners of home centers.

As a result, as in the past, only skilled workers do not always operate this automatic plane, and the number of scenes in which relatively inexperienced workers operate due to a chronic shortage of workers begins to increase. However, in extreme cases, it is more likely that it will be operated by people who are almost amateurs who have little opportunity to touch machines, and safety measures in response to changes in employment conditions. At the same time, the product liability law, the so-called PL law, has been enforced since last year, and it is now the time when more thorough safety measures for machinery are required than ever before. I am also facing the reality.

In this conventional automatic plane, as long as a horizontal shaft type rotary blade is adopted as a basic structure, even a highly skilled worker may be inadvertently inadvertently at a certain time and rotate laterally at high speed. Not only is there an accident that a finger touches the shaft-type rotary blade to cause serious injuries, and it is impossible to assume that an accident will accidentally occur in the current situation where the circumstances of workers have changed. There are circumstances, and even if it does not lead to a personal injury due to its basic structure,
There has also been a situation in which it is difficult to change the structure that may cause the expensive horizontal shaft type rotary blade to be damaged by inadvertently touching the object with the horizontal shaft type rotary blade, to another structure.

That is, as shown in the rear view of FIG. 6, the automatic plane device 1 is provided with a second surface plate 2 on which the wood to be processed is placed and slid forward and moved.
A guide bar 3 with a ruler for guiding the sliding movement of the wood is attached to the upper part of the so that its fixed position can be adjusted. Further, an elongated hole (not shown) for attaching the ruler 3 is formed in the second surface plate 2 so as to vertically penetrate therethrough, and the rear side of the guide bar 3 can be freely rotated in the elongated hole. The tip side of the bolt 32 inserted vertically through the holding base 31 having an L-shaped cross section is inserted and tightened with a nut (not shown) provided at the bottom of the second surface plate 2. It has a fixed structure.

On a part of the back surface of the guide bar 3, two fixed flanges 33 held by the moving base 31 are erected in parallel, and bolts 34 are inserted into these fixed flanges 33, 33 to insert the moving base 31. It is connected to
The lower back surface of the guide bar 3 is cut at a predetermined angle to form an acute-angled cross section. By loosening the bolt 34 for fixing, changing the angle, and tightening again,
As shown in the rear view of FIG. 7, the ruler surface 35 of the guide bar
It has a structure that can change the support angle of.

Further, the second surface plate 2 is an automatic plane device 1 shown in FIG.
As shown in the perspective view showing the schematic configuration of
It has a divided structure, a blade opening window 21 extending in the left-right direction is formed in the central portion, and a horizontal axis type rotary blade 4 having a rotation axis in the left-right direction is a part of the blade. Are laid out from the blade opening window 21 so as to be exposed on the surface of the surface plate 2 by a ratio corresponding to the cutting allowance, and the horizontal axis type rotary blade 4 is rotated at a high speed to slide. The back surface side of the moving wood W can be hooked with a predetermined hook.

Further, on the horizontal axis type rotary blade 4, the wood W is pressed against the guide bar 3 at the longitudinal side edge of the second surface plate 2 opposite to the side where the guide bar 3 is incorporated, and An elliptical horizontal shaft type rotary blade cover 5 for covering the upper part of the horizontal shaft type rotary blade 4 exposed on the surface plate 2 has a rotating shaft 51 standing on the side of the surface plate 2 as a rotating shaft, The guide bar 3 is pivotally mounted so that it can be eccentrically rotated in a horizontal plane, and is moved forward and backward in the left-right direction to adjust the position and the thickness of the wood W guided by the guide bar 3. Is done.

In the automatic plane device 1, a horizontal axis type rotary blade 4 is extended also on the back side of the guide bar 3, and the extended horizontal axis type rotary blade 4 part has a plurality of wide surfaces of wood W or wood boards. A first surface plate (not shown) for hooking is attached to the blade opening window 21 in a desired state. Then, above the horizontal axis type rotary blade 4 extended to the side of the first surface plate, the exposed horizontal axis type rotary blade 4 is protected, and a wood board to be hooked from above is provided. It is provided in a state in which a division type weight swinging (not shown) for pressing is covered, and the horizontal axis type rotary blade 4 is configured so as not to be left exposed on the surface side of the first surface plate. ing.

In the conventional automatic hoisting device 1 constructed as described above, the guide bar 3 is protected when the edge of the thin wood W is hooked or when it is hooked on a narrow timber. Adjustment is performed so that the wood W is pressed by the cover 5 to the position where the wood W is pressed, and the work of hanging the same member is repeatedly performed. In the case of such work, the guide bar 3 is largely fixed to the side of the protective cover 5 and is temporarily fixed. It is unavoidable that a part of the shaft type rotary blade 4 is left exposed. If the work is carried out in this state, a part of the exposed horizontal axis type rotary blade 4 is touched and bounced off, or if the object is a hard object such as a tool, an expensive horizontal axis type rotary blade The blade 4 may be damaged, and in the worst case, the operator's hand may touch it, resulting in serious injury.

Therefore, the inventor of the present invention, who is involved in the manufacture of an automatic plane device, has proposed to provide a rear surface protective cover 6 on the rear surface of the guide bar 3 which is located on the horizontal shaft type rotary blade 4, and has already manufactured the product. It has succeeded in becoming. The provided rear side protective cover 6 is provided with a hinge 61 at the base portion, is attached to the back surface of the guide bar 3 through the hinge 61 in a vertically rotatable manner, and at a plurality of positions from the base portion to the tip end. Hinged connecting parts 62, 62, ...
It was connected by ... so that it could be flexibly deformed by adapting appropriately to the uneven shape.

The back side protective cover 6 is made of, for example, a material such as a hard synthetic resin or a lightweight metal such as aluminum, and is usually provided on the upper side of the horizontal shaft type rotary blade 4 and is not shown. When the guide bar 3 is placed on the weight swinging rod and is moved to the protective cover 5 side, the guide bar 3 is moved together with the protective cover 5 to move between the split type weight swinging rod and the guide bar 3. Horizontal type rotary blade 4 exposed from the blade opening window 21
The horizontal axis type rotary blade 4 was prevented from being exposed. When the horizontal shaft type rotary blade 4 is to be maintained, it is necessary to move the split type weight swinging rod to expose the horizontal shaft type rotary blade 4 upward. In this case, the back side protective cover 6 is lifted up and inverted to the state shown by the chain line in FIG. 8 to prevent contact with the horizontal axis type rotary blade 4.

However, since the back side protective cover 6 by the inventor of the present application has a structure capable of contacting the horizontal shaft type rotary blade 4, a split type weighting swing rod (not shown) is used during maintenance work. When the back side protective cover 6 is inadvertently returned to the original closed state by forgetting to move it to the horizontal axis type rotary blade 4, the back side protective cover 6 is removed as shown by the solid line in the figure. There is a risk that the horizontal shaft type rotary blade 4 hangs down directly and the split type weight swing rod is closed on the horizontal shaft type rotary blade 4, resulting in a work error, and as a result, the horizontal type rotary blade 4 is damaged. There was

The inventor of the present application repeats trial manufacture and experiments to further improve such a defect, and the back side protective cover 6 itself is rotated by the horizontal axis type regardless of whether it is a skilled person or an unskilled person. The blade 4 is not in contact with the blade 4, and the back side protection cover 6 is closed before the split type weight swing rod, and thereafter, the split type weight swing rod is closed in the detour. In this case, the weight swing rod itself will be in an incompletely closed state and it will be easy to recognize that it has not been set to a normal state, making it easier and safer to perform maintenance work. The present invention has succeeded in developing and putting into practical use a rear side protective cover for an automatic plane device having an improved structure, and the configuration thereof will be described in detail below together with an example representing the present invention shown in the drawings. I will.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As will be clearly understood from the embodiments of the present invention shown in the drawings, the automatic plane device of the present invention basically has the following configuration. That is, the first horizontally arranged orthogonally to the horizontal axis rotary blade.
On the back side of the guide bar, which is built into the automatic plane having the surface plate and the second surface plate so that it can be moved and adjusted on the second surface plate,
A single plate-shaped cover body having a rectangular flat surface capable of roughly covering an appropriate range on the horizontal axis type rotary blade exposed by the movement and adjustment of the guide bar is a virtual vertical axis orthogonal to the axis of the guide bar. A protective cover for an automatic plane device, which is rotatable in a plane and is attached to a back surface of a guide bar by using a position corresponding to a horizontal position of a horizontal shaft type rotary blade as an attachment portion.

More specifically, with respect to a horizontal shaft type rotary blade which is horizontally installed at a high speed by using a transmission motor as a driving source, it is arranged in parallel in a direction orthogonal to the horizontal shaft type rotary blade and one of the first The surface plate is horizontally arranged below the horizontal axis type rotary blade,
The first surface plate and the second surface plate are combined so that the other second surface plate has a horizontal arrangement in which the blade exit window extends over the horizontal axis type rotary blade, while the first surface plate is combined. In the board part,
A plurality of weight oscillating rods are arranged in a keyboard-like arrangement that allows them to be in close contact with each other and to be independently oscillated vertically, and crosses over the horizontal axis type rotary blade in a transverse manner.
In addition, it is installed so that its posture is open, and in the second surface plate, parallel movement from the same place in the short side direction is performed on the longitudinal side edge that is the boundary with the first surface plate side. Adjustable,
A guide bar having the second smoothing plate main smooth surface side as a ruler surface and the opposite side edge as a supporting portion are rotated on the smooth surface around the vertical axis to expose the horizontal axis rotary blade. On the opposite side of the ruler surface (to the side of the ruler surface) with respect to the automatic plane device, which is constructed so as to straddle over the second surface plate portion and which has a structure that allows wood to be pressed against the guide bar ruler surface side. On the rear surface of the guide bar, which is the side facing the first surface plate), the position corresponding to the horizontal installation position of the horizontal shaft type rotary blade should be the attachment part, and the appropriate range on the horizontal shaft type rotary blade should be roughly covered. An automatic plane which is attached to the guide bar so that the cover body in the shape of a rectangular flat plate that can be rotated is rotatable in a virtual vertical plane orthogonal to the axis of the guide bar. It can be shown as a protective cover for the device.

Most of the automatic planes are those of companies that have already been commercialized and put into practical use, and most of them are in the work line, that is, the direction from the material feeding side to the material drawing side. In order to mainly finish a square wood such as a pillar wood, a rafter wood, a joist wood, etc. in a plane, the target wood W is placed and moved, and the surface of the wide wood is mainly used. Alternatively, a second surface plate for narrow side surface finishing or side surface inclination finishing is provided adjacent to and in parallel with each other, at a position common to the first surface plate and the second surface plate orthogonal to the work line. The horizontal axis rotary blade is installed so as to rotate at a high speed using an electric motor as a power source, and the first surface plate described above has its surface smooth surface horizontal below the horizontal axis rotary blade. Placed and in the size of wood W On the other hand, the second surface plate has a surface smooth surface of the horizontal axis type rotary blade of which the distance between the horizontal axis type rotary blade and the horizontal axis type rotary blade is adjustable. It is arranged so as to be horizontal above, and has a blade opening window in the laterally installed portion of the horizontal shaft type rotary blade, and a part of the horizontal shaft type rotary blade becomes exposed from the same place, No. 2 so that the exposed condition (cutting allowance) of the blade can be adjusted
The surface plate itself is also structured to be vertically adjustable.

A guide bar for positioning the target wood W is provided on the side edge of the second surface plate along the working line, which is the side surface of the first surface plate, on the side of the ruler surface. With the side facing the other side edge, the second surface plate is mounted so as to be movable in parallel in a direction orthogonal to the work line on the smooth surface,
The angle of inclination with respect to the smooth surface is 90 degrees toward the first surface plate side.
While the angle can be freely changed from ° to an appropriate angle,
On the other side edge in the direction along the work line, the horizontal shaft type rotary blade is rotated around the vertical axis on the same smooth surface with the horizontal shaft type rotary blade horizontal position (near the blade exit window) as the pivoting position. Most of them are formed in a structure in which a partially elliptical protection plate is incorporated, which straddles over the exposed second surface plate portion and allows the wood to be pressed to the guide bar ruler surface side. .

The rear side protective cover basically moves on the smooth surface of the second surface plate with the guide bar which is positionally adjustable in the direction of its short side, and as a result, the rear side of the guide bar has the second side surface. A member that functions to safely protect the top of the horizontal axis type rotary blade that is exposed from the blade exit window of the bottom plate, and that has the strength and shape necessary to fulfill the protective function. For example, it is a single plate made of a light synthetic metal plate such as a hard synthetic resin plate or aluminum, and has a length of at least the moving width for adjusting the position of the guide bar, and a blade It is formed as a rectangular shape or other planar shape having a width required to safely protect the upper portion of the horizontal axis type rotary blade exposed from the window. In addition, the cover body of the rear side protective cover has a structure in which it is prevented in advance that the split type weight swing rod will come into contact with each other, or the wood W itself, a tool or the like will be damaged. If it is necessary, a cushioning member made of an appropriate material such as urethane foam or sponge may be attached to at least the side facing the horizontal axis type rotary blade side.

The mounting structure for the guide bar is as follows.
Connecting by screwing by directly processing a screw hole on the back of the guide bar, connecting a bolt and screw by forming a through hole, or attaching a bracket to the back of the guide bar by appropriate means and inserting it from above. It is possible to employ a fitting structure, or a bonding structure in which welding is performed directly, or other suitable connecting means. In addition, the guide bar is generally manufactured by cutting cast iron etc., and the one that has reinforcing ribs on the back for flesh stealing is currently mainstream, and the back side protective cover is When attaching, it becomes necessary to match the attaching portion with the height of the reinforcing rib, so there may be a case where it is necessary to attach via a spacer or the like for forming an attaching surface with screws or the like.

Further, the rear side protective cover is assumed to be simply attached to the rear side of the guide bar so that its base end side is butt-shaped, and is bent in the rotating direction near the base end portion. When the free end side of the back side protection cover is turned upward, the center of gravity moves to the ruler surface side protection cover side of the guide bar from the turning pivot, The cover body may be held in an upright posture. Furthermore, it is assumed that a support piece is formed by projecting on the back side of the base of the cover body, and when the back side protective cover covers the horizontal shaft type rotary blade, the tip of the support piece is a guide bar. The cover body is configured so as to be in contact with the back surface or its reinforcing ribs so that the cover body can be securely held in a non-contact horizontal posture by the horizontal shaft type rotary blade, or a bolt or the like is attached to the back surface of the guide bar. As a result, the height of the portion for receiving the supporting piece can be appropriately set as needed, and when the rear side protective cover is in the upright state, the supporting piece projects to the side of the swing rod with the split mold. The amount can be reduced so that the supporting piece and the split type weight do not come into contact with the swing rod. Detailed description will be made below regarding the embodiments shown in the drawings so that the configuration of the automatic plane device included in the present invention can be grasped more specifically and clearly.

It has an excellent feature that it is possible to reliably prevent the occurrence of unexpected accidents such as harm.

Further, since the rear side protective cover of the present invention is itself supported on the rear side of the guide bar so as to be supported in a substantially horizontal shape, the rear side protective cover is divided into the rear side protective cover. Even if the weight swing rod is accidentally rotated, these split-type weight swing rods will not fit into their proper posture and will stop in an abnormal state. However, there is a risk that the abnormal posture can be recognized and the automatic plane device will malfunction, causing both the horizontal shaft type rotary blade and the rear side protective cover to come into contact with each other, scratching or damaging them. It can be said that not only will it be completely eliminated, it will not only greatly contribute to ensuring safety, but will also greatly contribute to improving work efficiency.

In particular, the rear side protective cover 13 of the first embodiment shown as a constitution representative of the present invention has an extremely simple attachment structure to the rear surface of the guide bar 12 in addition to the above-mentioned characteristics, and also has an upper portion. Even when the cover body is turned to the upright state, the center of gravity of the free end side of the cover body is located on the ruler surface side of the guide bar 12, and a stable state can be maintained.
This has the advantage of eliminating the inconvenience of inadvertently falling over and disturbing the work during maintenance. Further, the rear side protective cover 13 taken up in the second embodiment has the guide bar 12.
Even if the structure of the mounting portion on the back surface is a portion without the reinforcing ribs 12c, the mounting can be performed without any trouble. It is possible to exhibit the convenience of enabling attachment to an automatic plane or retrofitting.

As described above, the protective cover of the automatic plane device of the present invention is easy to manufacture and can be provided at a relatively low cost because of its structure, and it is easy to install and can be used in almost any type. In addition to being able to be adopted in automatic planes, it is possible to reliably guarantee the safety of work, and especially when the product liability guarantee system is enforced In addition, it is possible to correctly respond to the recent social demands, and it is expected that it will be highly evaluated by various parties including timber processors.
