That is, the driving roller 51 is driven to move the moving rollers 52a and 52b, so that the base 49 connected and fixed to the endless belt 53 stretched around the moving rollers 52a and 52b is held between the holding mechanism traveling rails 50. It will move along.

  The peeling of the bark S of the plant P by the peeling apparatus 10 of the present embodiment having the above configuration will be described in detail based on the drawings. In each drawing, parts other than the main components are omitted. First, the state before introducing the plant P is a state in which the right chuck member 33 and the left chuck member 34 according to the separation mechanism 31 of the bark separation means 30 cross each other as shown in FIGS. 1 and 3A. In the closed state, the separation mechanism 31 is arranged at the uppermost position by the separation moving means 32. Further, the clamping mechanism 41 related to the bark peeling means 40 is fixed by the locking member 55 by the link mechanism in a state where the expansion / contraction mechanism 45 is contracted, as in the state shown in FIG. Is maintained in an open state and is waiting in the vicinity of the bark separating means 30.

  When the plant P to be peeled is input to the raw material input unit 20 by the raw material input guide 21, a pair of upper and lower guide rollers 23a in which the tip of the plant P is disposed in the raw material input unit 20, as shown in FIG. 23b is pulled into the apparatus main body X. And since the raw material injection | throwing-in part 20 which concerns on this embodiment is equipped with the bark cleaving blade 24 adjacent to the induction | guidance | derivation rollers 23a and 23b, in the process in which the plant P is drawn in by the induction | guidance | derivation rollers 23a and 23b, A cut C can be formed in the bark S along the longitudinal direction of the plant P (see FIGS. 3B and 4B).

  The tip of the plant P input from the raw material input unit 20 has passed between the right chuck member 33 and the left chuck member 34 constituting the separation mechanism 31 related to the bark separation means 30 by a sensor (not shown) or the like. If detected, the driving of the guide rollers 23a and 23b is stopped, the air cylinder 38 of the separating moving means 32 related to the bark separating means 30 is activated, and the separating mechanism 31 starts moving downward. Then, the right chuck member 33 and the left chuck member 34 that have been urged in a state where the tip portions intersect (closed state) are moved downward while rubbing the surface of the plant P with a saw blade at the stage of contacting the plant P. In the process of continuing the movement, the bark S of the plant P is separated from the plant P (see FIGS. 3C and 3D), and finally the right chuck member 33 and the left chuck member 34 according to the separation mechanism 31 are used. Then, the bark S at the tip portion separated from the plant P is sandwiched (see FIG. 3 (e)).

  At this time, the fixed state of the expansion / contraction mechanism 45 constituting the clamping mechanism 41 related to the bark peeling means 40 fixed by the locking member 55 of the link mechanism is fixed by the release arm 39 included in the support arm 36 related to the separation mechanism 31. When the telescopic mechanism 45 is released and the pair of left and right sandwiching members 43 and 44 related to the sandwiching mechanism 41 is closed (see FIG. 2A), the bark S is sandwiched. (See FIGS. 3 (e) and 4 (c)).

  When the separation mechanism 31 with the bark S of the plant P sandwiched by the separation moving means 32 related to the bark separation means 30 reaches the lower end, the right chuck member 33 and the left chuck member 34 related to the separation mechanism 31 are opposite to each other. When the side abuts against the stopper 26 provided on the apparatus main body X, the right chuck member 33 and the left chuck member 34 rotate about the pin 35, and the state in which the bark S is held by the separation mechanism 31 is released. (See FIG. 3 (f) and FIG. 4 (c)).

  When the bark S is pinched by the pinching mechanism 41, it is approximately the direction in which the pinching mechanism 41 is moved away from the plant P by the peeling moving means 42 associated with the bark peeling means 40, in this embodiment, the direction in which the plant P is charged. It is moved in the reverse direction (see FIG. 4D). At this time, the bark S is folded back by the bark folding roller 25 disposed in the raw material charging unit 20, and in this state, the clamping mechanism 41 that clamps the bark S is moved by the peeling moving means 42. The bark S can be peeled off from the plant P, and the plant P from which the bark S has been peeled is discharged out of the device main body X from the discharge portion 60 formed on the side surface of the device main body X (FIG. 5 (a) (b)).

  When the peeling of the bark S from the plant P is completed and the pinching mechanism 41 reaches the end of the pinching mechanism running rail 50 by the peeling moving means 42, the opposite side of the pinching members 43 and 44 related to the telescopic mechanism 45 is the device main body X. The expansion / contraction mechanism 45 is contracted by abutting on the stopper 56 provided on the clamp member 50 to open the clamping members 43 and 44 (see FIG. 2B), and the bark S clamped by the clamping members 43 and 44 is moved to the apparatus main body X. The pinching members 43 and 44 that have fallen into the interior and that have been contracted and opened by the telescopic mechanism 45 are fixed by the locking member 55 in this state (see FIG. 5C).

  Then, the separation mechanism 31 is returned to the initial position by the separation moving means 32 related to the bark separation means 30, and the holding mechanism 41 is returned to the initial position by the peeling movement means 42 related to the bark peeling means 40. The preparation of the bark S of the plant P is prepared (FIG. 5 (d)).

  As described above, according to the peeling apparatus 10 of the present embodiment, the bark S of the plant P can be easily and efficiently peeled without requiring manual labor. In particular, according to the configuration of the peeling apparatus 10 of the present embodiment, bark of bark that is steamed from Japanese paper raw material can be peeled off very efficiently and easily.

  Moreover, since the raw material input part 20 which concerns on the peeling apparatus 10 of this embodiment is equipped with the bark cleaving blade 24 for forming the cut | interruption C in the bark S along the longitudinal direction of the plant P, it is the further of a peeling operation | work. Efficiency can be improved.

  Furthermore, by providing the raw material input unit 20 according to the skinning apparatus 10 of the present embodiment with a pair of guide rollers 23a and 23b for guiding the plant P to the bark separating means 30, it is possible to further improve the efficiency of the skinning operation. Also, mechanization of the work of introducing the plant P into the apparatus main body X is possible.

  As mentioned above, although embodiment of this invention was explained in full detail, it should not be understood that the technical idea of this invention is limited substantially. For example, in the skinning apparatus of the present invention, the raw material charging unit does not necessarily have a guide roller, and a plant as a raw material may be manually introduced into the skin separation means.

  In addition, the guide rollers 23a and 23b according to the peeling apparatus 10 of one embodiment of the present invention are arranged in a pair of upper and lower sides, but the arrangement mode of the guide rollers is not limited to a pair of upper and lower sides, and a pair of left and right or one drive The guide roller may be configured by only the roller.

  Furthermore, in the peeling apparatus 10 according to an embodiment of the present invention, the bark cleaving blade 24 is disposed in advance in the raw material charging unit 20, but it is not always necessary to dispose the bark cleaving blade 24, and a cut is made in advance. If this is the case, it is not necessary to arrange a bark cutting blade on the device itself. Further, the bark may be cut simultaneously when the bark is separated by the bark separating means. Further, the arrangement position of the bark cutting blade is not particularly limited, and may be arranged at any position as long as a cut can be formed as a pre-process of the separation work by the bark separation means.

  Further, in the peeling apparatus 10 according to one embodiment of the present invention, in the separation mechanism 31 related to the bark separation means 30, a plurality of right chuck members 33 and a plurality of left chuck members 34 alternate their tip portions. However, the configuration of the separation mechanism 31 is not limited to this, and it may be composed of only a pair of the right chuck member 33 and the left chuck member 34, and the present invention provides the gist thereof. In the range which does not deviate from this, it can implement, improving, changing or adding suitably according to the ingenuity and the idea of those skilled in the art.
