Description

[Detailed Description of the Invention] <Industrial Application Field> This invention collects peeled skin by receiving it in a skin collection gutter, and uses the rotation of a peeling blade to forcefully place the skin on the side. This relates to a wood peeling barker with a bark recovery device which is moved to a discharge conveyor and discharged, the height of the wood bark barker is lowered, the installation is simple, and the wood can be easily loaded.

<Prior art> As shown in Fig. 2, the wood peeling barker that has been commonly used in the past has open parts b and c at the top and bottom of a wood peeling tank a, with the lower open part c facing the open part c. It is constructed by disposing a rotating body e provided with a peeling blade d in the longitudinal direction, and in order to collect the skin, a collection plate f is disposed below the rotating body e, and a collecting plate f is disposed below the rotating body e. The skins are collected and moved by a conveyor g installed for discharging the skins. An example of a structure similar to this is shown in Japanese Patent Laid-Open No. 151301/1983.

In addition, as shown in Japanese Patent Application Laid-Open No. 57-96804, there is also a type in which a rotary body with a rotatable peeling body is provided at the bottom of the cylinder body, and a skin collection gutter is disposed below it. .

<Problems to be Solved by the Invention> However, in such a collection method, in order to ensure that the skins that have fallen onto the collection plate f fall smoothly onto the skin discharge conveyor g, the angle of the collection plate f must be adjusted to a certain degree. Since the slope must be steep and the peeling conveyor g must be installed below it, a considerable height is required at the bottom of the rotating body e, resulting in a reduction in the installation height of the wood peeling barker. This has the disadvantage that the height has to be increased, which makes the installation troublesome, and the wood loading section is also high, making loading work troublesome. Conventionally, in order to prevent the installation height of the wood peeling barker from becoming too high, a concave groove was constructed in the ground, and the peeling conveyor g was installed inside this groove. However, this was accompanied by the inconvenience of having to carry out the construction, which of course increased the construction costs.

Furthermore, what is shown in JP-A No. 57-96804 is a modification of the conventional so-called drum barker, in which instead of rotating the drum, the wood inside the drum is debarked by the impact force of the debarking body. Since it is necessary for the peeling body to hammer the wood, the peeling body is rotatably disposed on the rotary body and has a considerable size in order to increase the inertial force. Therefore, there is a fairly large gap between the rotating body and the skin collection gutter, and the peeling body is also rotatably arranged, so in reality, the skins that have fallen onto the skin collection gutter smoothly flow into the skin discharge port. It will not be scraped out.

<Means for Solving the Problems> Therefore, in order to solve the above-mentioned problems, the wood peeling barker with a bark recovery device according to the present invention has the following features:
Openings are formed at the top and bottom of the wood peeling tank, and a cylindrical rotating body is placed below facing the opening at the bottom, and the total height of the cylindrical rotating body is sufficiently low relative to the diameter of the cylindrical rotating body. While fixing the peeling blade to the rotating body,
A curved shape is formed below the rotating body so as to be slightly spaced from the peeling blade, and
A skin collection gutter is installed so that the skin discharge side is higher than the bottom of the rotating body, and the skin collection gutter is placed parallel to the skin discharge side so that the skin that falls into the skin collection gutter is moved and discharged. A discharging conveyor is installed, and the skin that falls into the skin collection gutter is forcibly scraped out by a peeling blade using the rotation of the rotating body, and the skin is dropped onto the skin discharging conveyor. It is designed to be moved and discharged.

<Example> Next, an embodiment of the wood peeling barker with a bark recovery device according to the present invention will be described based on the drawings. Reference numeral 1 is a wood peeling tank having upper and lower openings, and 2 is a wood peeling tank. 1 is a long cylindrical rotating body disposed in the downward longitudinal direction. That is, the rotating body 2 serves as the bottom of the wood peeling tank 1. 3 is a peeling blade fixed to the rotating body 2, and the peeling blade 3 can be of any desired shape such as a saw blade or a chip blade;
The height of the peeling blade 3 is sufficiently lower than the diameter of the rotating body 2. Since the entire rotary body 2 serving as the bottom of the wood peeling tank 1 rotates, even if the height of the peeling blade 3 is low, the wood can be sufficiently oscillated and peeled. Then, the rotating body 2 is moved by the arrow a by the motor M which is decelerated in two stages via the chain C and the V-belt V.
It is configured to rotate in the direction of

4 is a fixed side plate in which elongated holes 5, 5' are vertically bored at intervals in the longitudinal direction;
This is an openable/closable side plate that is rotatably arranged in the direction of arrow b. 8 is a chain connected to the upper part of this openable side plate 6, and this chain 8 is connected to a lower sprocket 10' via a sprocket 10 of a bearing 9.
The upper chain block 11 is connected to the upper chain block 11 by bypassing the upper chain block 11. The openable/closable side plate 6 is designed to rotate in a range from a substantially vertical position to a horizontal position.

Reference numerals 12 and 12' designate rotating shafts that are rotatably disposed on support rods 13 and 13', respectively, outside the wood peeling tank 1. The support rods 13, 13' are arranged so as to be biased toward the stationary side plate 4 by a spring 14. As a result, the rotating shafts 12, 12' are also urged toward the stationary side plate 4. 15,1
Reference numeral 5' denotes an auxiliary peeling blade disposed on the rotating shafts 12, 12', and the auxiliary peeling blades 15, 15' are composed of, for example, a wire brush or a chip blade. In the illustrated example, a wire brush is used. As shown in the figure, a portion of the auxiliary peeling blades 15, 15' faces into the wood peeling tank 1 through the elongated holes 5, 5'. On the other hand, driven sprockets 16 and 16' are provided at one end of each of the rotating shafts 12 and 12'. In addition, each support rod 13, 1
Drive shafts 17, 17' are inserted through 3', and drive sprockets 18, 18' are respectively disposed at positions corresponding to the driven sprockets 16, 16'. The driven sprockets 16, 16' and the driving sprockets 18, 18' are connected by chains 19, 19', respectively. A large pulley P is attached to one end of the drive shaft 17, 17'.
P' is arranged and connected to motors M', M'' by V-belts V', V''.

Reference numeral 20 denotes a skin collection gutter which is arranged in a curved manner below the rotary body 2 and along the rotary body 2, and this skin collection gutter 20 is arranged so that there is a slight gap between it and the peeling blade 3. It is set up. Since the height of the peeling blade 3 is low, the space between the rotary body 2 and the skin collection gutter 20 is also
It won't be that big. Reference numeral 21 denotes a skin discharge conveyor disposed at the lower side of the rotary body 2 on the side of the openable side plate 6, and is provided at a higher position than the lower side of the rotary body 2. The skins that fall from the skin discharge section provided at a higher position than the lowest part of the rotating body 2 fall onto the skin discharge conveyor 21.

<Function> Thus, the motor M is driven to rotate the V-belt V and the chain C to rotate the rotating body 2, and the motors M', M'' rotate the V-belts V',
The large pulleys P, P' rotate through the drive shafts 17, 17', the respective drive sprockets 18, 18' rotate, and the chains 19, 1
9', each driven sprocket 16, 16' is rotated, and the respective auxiliary peeling blades 15, 1
5' will rotate. At this stage, the wood is put into the wood peeling tank 1. Then, the wood is swung and danced wildly from below to above by the rotating body 2.
The peeling blade 3 of the rotating body 2 acts as a peeling blade. When the roughly peeled wood comes into contact with the auxiliary peeling blades 15, 15', the last thin skin of the wood is removed by the wire brush so as to be polished cleanly. In addition, if the wood collides strongly with the auxiliary debarking blades 15, 15',
Since the rotating shafts 12, 12' can be rotated by the spring 14, the auxiliary peeling blades 15, 15'
moves out of the fixed side plate 4 through the elongated holes 5, 5', thereby preventing unnecessary damage to the wood. Further, each rotating shaft 12, 12' is connected to an independent support rod 13,
The auxiliary skinning blades 15, 15'
It is also possible to move individually, and those with strong collisions can release the force of the collision.

The skin peeled by the skinning blade 3 of the rotary body 2 falls into the skin collection gutter 20 from between the rotary body 2 and the wood peeling tank 1. Then, the skin on the skin collection gutter 20 is scraped out by the peeling blade 3 by the rotation of the rotating body 2, and falls onto the skin discharge conveyor 21, and is moved and discharged to the outside of the wood peeling barker.
Since the peeling blade 3 is fixed to the rotating body 2, it can forcibly scrape off the skin on the skin collecting gutter 20, and since the distance between the rotating body 2 and the skin collecting gutter 20 is not so large, the peeling blade 3 is fixed to the rotating body 2. The skin collection gutter 20 is also opened by the rotation of 2.
The upper skin will also be scraped off directly. Therefore, peeled skins do not stay between the rotary body 2 and the skin collection gutter 20, and the gutter does not become clogged.

When the peeling is completed, all operations are stopped, the retractable side plate 6 is rotated to a horizontal position, and the wood is removed using a forklift or the like. In this case, the chain 8 is driven in the extending direction by the chain block 11, and the opening/closing type side plate 6 is rotated so as to be horizontal. Then, since the retractable side plate 6 is located at a lower position than the top of the rotating body 2, the wood in the wood peeling tank 1 automatically falls onto the retractable side plate 6. Once the wood has been removed, the chain 7 is pulled up, the retractable side plate 6 is erected, new wood is introduced, and the barking process is performed.

<Effects of the Invention> As described above, according to the wood peeling barker with a peel recovery device according to the present invention, openings are formed at the top and bottom of the wood peeling tank, and a cylindrical cylinder is formed downward facing the lower opening. A cylindrical rotating body is provided, and a peeling blade whose total height is sufficiently low relative to the diameter of the cylindrical rotating body is fixed to the rotating body, and a peeling blade is placed below the rotating body with a slight distance between the peeling blade and the peeling blade. A skin collection gutter is formed in a curved shape along the rotating body so that it is free, and the skin discharge side is located at a higher position than the bottom of the rotating body, and the skins that have fallen into the skin collection gutter are moved. Since the skin discharge conveyor is installed parallel to the skin discharge side of the skin collection gutter, the skins that have fallen onto the skin collection gutter can be reliably scraped to the skin discharge conveyor side, and the skin can be removed from the machine. Since the entire structure can be made smaller, installation and construction of the wood peeling barker becomes easier, and the work of inserting wood becomes easier.
