Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parr release device for an automatic parr material feeder.

・The automatic par material supply machine automatically feeds par material one by one into the automatic par material processing machine that automatically processes par material continuously. machine is being developed.

However, the problem with conventional automatic par material feeding machines is that the incoming par is released along the extension of its reciprocating path, so the total length of the automatic par material feeding machine must be increased by the length of the incoming par. This was a very unfortunate situation.

・The length of the feeding par of automatic paring material feeding machines is so long that it occupies a very large proportion compared to the length of the automatic paring material feeding machine itself.
As C control progresses, processing specifications for par materials become more diverse.
Since the movement range of the main axis ft of automatic par material processing machines tends to become longer, the feeding par itself has to be lengthened accordingly. Therefore, if the infeed parr, which is becoming longer, is allowed to escape on the extension of its reciprocating path as in the past, the total length of the automatic parr material feeder will become longer and longer, and the installation This has become a very big problem in terms of space.

Therefore, an object of the present invention is to shorten the total length of the conventional automatic material feeder by the protruding length of the feeding par.
An object of the present invention is to provide a material relief device.

This object of the invention is achieved by causing the infeed par to escape into a position off the reciprocating path rather than in an extension of its reciprocating path.

Therefore, by providing the feeding parr relief device of the present invention, the total length of the automatic lumber material feeder can be shortened to approximately the same length as the parr material to be fed.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Before going into the specific explanation of the feeding par release device of the present invention, in order to further clarify the basic concept of the present invention,
Automatic par material feeding machine (hereinafter simply referred to as "par material feeding machine J") and automatic par material processing machine (hereinafter simply referred to as "par material processing machine")
This section explains the mutual relationship between

FIG. 1 shows a par material feeder 10 equipped with the feeding/gut release device 50 of the present invention (FIGS. 2 and 3), a conventional par material feeder 10', and these par material feeders. FIG. 2 is a schematic diagram showing the relationship between the par material processing machine 12 and the par material processing machine 12 in conjunction with the machine.

However, for convenience of explanation, the par material processing machine 12 is shown enlarged compared to the par material supply machine 10, 10'.

The par material processing machine 12 includes a spindle, that is, a main shaft 14.
,/N- Prevents swinging of the par material during machining, but ID 16
, a stand 18 on which a machining tool is attached, etc. are provided. Of these, the main shaft 14 can move within a certain range/, depending on the specifications of the material to be machined. On the other hand, since it is necessary to feed the par material through the main shaft 14, the feed-in parser 20 needs to have at least the length shown in the figure [h], but in reality it is connected to other auxiliary equipment. From the relationship of I! The length shown in 3 is required.

Although the length of the injected parr 20 is very long as described above, in the conventional parr material feeder 10', the new parr row group 24 to be supplied next (this new parr row group is In order to take in the paring material one by one from the material feeder (which is placed on the supply shelf of the material feeding machine), the tip 2 of the feed nozzle 20 is
6 (to be precise, the tip of the finger chuck 28, as the finger chuck 28 for gripping the par material is attached to the tip of the feeding par 20) at least holds the rear end 30 of the new par row group 24. The reciprocating movement path of the feeder 4-20 had to be reciprocated until it exceeded the position. For this reason, the conventional material feeder 10'
Compared to the par material feeder 10 equipped with the feeding par release device of the present invention, the length of the feeding par 20 is significantly longer! This means that the length will have to be increased by 4.

On the other hand, in the wood supply machine 10 equipped with the feeding parr release device of the present invention, even when seven pieces of wood are taken in from each new par row group 24, the feeding parr 20 is moved to the rear end 32. It is simply moved back to a position where it does not protrude from the rear end 30 of the new par material group 24. However, if this continues, the feed parr 20 will exist at the position where the next new par material to be supplied is to be taken in (i.e., the reciprocating path of the feed par material), and it will not be possible to take in the new /J- material. It becomes impossible.

Therefore, a button is provided to temporarily release the fed parr 20 to a position away from its reciprocating path (for example, a position parallel to the reciprocating path) only while a new par material to be supplied next is taken in. In other words, 9 included, 2-2
A guide rail (this guide rail is indicated by the symbol A in FIG. 3 and has the function of supporting and guiding the par material) is housed so that the feeding par 20 can slide therein. , it is released to a position away from the reciprocating path of the feeding par. However, simply by allowing the feeding par 20 and the idle rail A to escape, it is still not possible to take in a new par material 24. The reason for this is that the idle rail A, which is meant to take in and support the timber, has escaped. Therefore, at the same time that the feeding par 20 and the idle rail A escape, another guide rail B (FIG. 3) is positioned on the original reciprocating path.

However, with this alone, it is impossible to automatically supply the par material to the par material processing machine by supplying the par material. The reason for this is that the rear end 30 of the newly supplied par material is located far behind the tip 34 of the finger chuck 28 of the fed par material 20, which is already a release, so the rear end 30 of the par material is This is because it is impossible to grip it with the chuck 28. For this reason,
A feeding plate 51 is provided that is newly positioned on the original reciprocating path but can slide inside the idle rail B. This feeding plate 51 pushes the rear end 30 of the parr material and removes the escaping feeding parr. The rear end 30 of the paring material is moved forward to be positioned in front of the tip of the finger chuck 28. Therefore, if the escaping feeding parser 20 is returned to its original reciprocating path, the guide rail B and the feed plate 51 therein will escape to a position away from the reciprocating path. ), the par material and the feeding par 20 are lined up in a straight line on the reciprocating path of the feeding par, and the rear end 3o of the par material has a fin positioned in front of the chuck 28, so it is the same as before. When the feeding par 20 is advanced, the rear end 30 of the par material is inserted into the finger chuck 28, and from then on, the par material can be supplied to the wood processing machine 12.

The above is a general description of the feeding par relief device of the present invention, but the feeding par relief device 50 of the present invention will be specifically explained based on the schematic plan view of FIG. 2 and the perspective view of FIG. 3.

FIG. 1 is a schematic plan view showing the process of automatically and continuously supplying par material to the par material processing machine 12 by the par material supplying machine 10 equipped with the feeding and par release device 50 of the present invention. , members that are the same as those shown in FIG. 1 are designated by the same numbers.

FIG. 2 (1) shows that the remaining part (residual material) 40 of the par material that has been completely processed by the par material processing machine 12 is moved back while the fins of the feeding par 20 are held by the chuck 28, and the remaining part 40 is removed. The leftover material 40 is shown falling into a box 41.

The rear end 32 of the infeed nozzle 200 is retracted along the reciprocating path C of the infeed Z-20 to a position where it does not protrude from the rear end 30 of the next new row of bars 24 to be fed. Number 42 is a guide rail fixed to the par material feeder 10.

FIG. 2 (2) shows that in order to newly supply par material, the feeding par release device 5o of the present invention is activated, and the feeding par material is fed in.
-20 and its guide rail A are shown being released to a release position C' which is deviated from the reciprocating path C. At the same time as the feeding par 20 and its guide rail A are released to the release position C', the par material 24' taken in is moved to the original reciprocating path C (Fig. 1 (3)).
The shortcut position D of the par material processing machine 12 (Fig. 2 (
The feed plate 51 for advancing to 4)) and the guide rail B that accommodates the feed plate 51 are positioned integrally.

Since the feed plate 51 is only used to push the rear end of the newly introduced girder 24' forward, its wall thickness may be thin enough to maintain its elongation. There is no need to make it as long as -20. When the idle rail B is positioned on the reciprocating path C, the feed plate 51 is positioned slightly behind the rear end 30 of the bar row group 24, and does not interfere with the intake of the paring material 24' to be supplied next. It's like that.

FIG. 3(3) shows the state in which the new support material 24' has been inserted into the idle rail B and the fixed guide rail 42.

FIG. 1 (4) shows that the feed plate 51 is used to feed the new par material 2.
4' is shown advanced to the shortcut position of the material processing machine 12.

FIG. 2 (5) shows the guide rail A and the feeding par 20, which had been released to the relief position C', returned to the original reciprocating path C, and the feeding par 20 is then moved forward. While gripping the rear end of the pawl material 24' with the finger chuck 28, the pawl material 24' is gradually fed in accordance with the machining process of the processing machine 12.

FIG. 3 is a perspective view showing a state in which the feeding parr relief device 50 of the present invention, which performs the operations described above, is mounted on the parr material supplying machine 10.

The figure shows that the feeding par 20 itself is housed within the guide rail A, so the feeding par 20 itself cannot be seen, but the feeding par 20 is fixed to the feeding arrow 21 provided at the rear end. has been done. The feed arrow 21 can be connected to and disconnected from a chain 23 for reciprocating the feed parr 20, but this is a well-known type that is also used in conventional par material feeders. Detailed explanation will be omitted.

But almost below Idrail A is another Idrail/I/B.
A feed plate 5 is provided in this guide rail B.
1 is accommodated. The feed plate 51 is connected to its drive motor 2.
5 and a chain 27 for reciprocating movement. In reality, a guide plate is provided that allows the feed plate 51 to reciprocate along the par material feeder 10.
This guide plate has been omitted for clarity of illustration.

The drive motor 25 and left sprocket 29 are
It is fixed to a support member 52, which will be described later, via a suitable support bracket, and is configured to move integrally with the support member 52.

The upper and lower guide rails A and B are fixed to left and right/paired crotch arms or support members 52 that are open at a certain angle.

B are arranged at regular intervals.

In the illustrated state, the guide rail B feeds the par 20 along the reciprocating path C (this reciprocating path C is the par material 24'
is the path along which the par material is sent to the par material processing machine, which also coincides with the par material path of the fixed guide rail 42). That is,
This figure shows the guide rail A and the feeder par 20 running away to the release position C'.

A support member 52 that fixes the guide rails A and B is pivotally supported by a support bracket 53 that is fixed to the par material feeder 10&C. The left and right pair of support members 52 are the shafts 5
4 and are integrally fixed to each other. A gear is fixed to the shaft 54, and this gear 55 meshes with a gear 57 attached to the shaft of a drive motor 56. Therefore, by rotating the drive motor 56 in the normal or reverse direction, the support member 52 pivots within a certain range, moving the guide rail A and the feeding par 20 to either the reciprocating path C position or the relief position C'. It is possible to position it in position. When the guide rail A and the feed plate 20 are positioned at the position of the reciprocating path C, the other guide rail B and the feed plate 51 are positioned at another relief position C"
It is natural that they would be forced to flee.

In the embodiment described above, the support member 52 that supports the idle rails A and B is connected to the drive motor 56 and the gear pair 55.
57, but instead of the drive motor 56 and the gear pair 55, 57, a hydraulic cylinder (not shown) may be used to drive the support member 52 up and down. It is clear that it is possible.

It is also possible to reverse the positions of the idle rails A and B so that the guide rail A, on which the feeder 20 runs, is on the bottom, and the idle rail R, on which the feed plate 51 runs, is on the bottom.

Since the guide rail release device of the present invention is configured with more than 50 pieces, the total length can be greatly shortened compared to the conventional par material feeder.
