Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a tilting device for a disc-shaped rotary blade of a device used when processing fish such as opening the fish or dropping it into three pieces.

(Prior Art and Problems) Most of the tilting devices for rotary blades that are commercially available in the past are tilted together with the bearing frame that supports the rotating shaft, and the device becomes large and it is difficult to make fine adjustments.

Especially when opening a fish, it is necessary to move not only the tilt angle of the rotary blade but also the cutting position depending on the size and type of the fish. Has dropped. In addition, the manufacturing cost is high, which eventually increases the fish processing cost.

(Problems to be solved) This invention is to simplify the structure, to easily adjust the inclination angle and the cutting position of the rotary blade, to prevent failures, and to reduce the cost. It is intended to be provided to.

(Means for Solving Problems) The present invention has a disc type rotary blade for cutting a fish which is sandwiched and conveyed between belt conveyors of a sandwiching and conveying unit of a pair of left and right sandwiching type belt conveyors, and a mechanism for changing the inclination angle and the cutting position is provided In the device supported by the machine frame via a machine frame, at least one of the rotary blades has a tilt angle and a cutting position changing mechanism that includes the following components a) to d). It is a tilting device of a rotary blade. That is, (a) a horizontal horizontal guide member, which is perpendicular to the conveyor method of the belt conveyor, is fixed to the machine frame, and a movable member slidably fixed to the guide member conveys the belt conveyor. Vertical guides are provided at two locations near and slightly away from the section, respectively, in a direction perpendicular to the transport direction.

(B) Each of these vertical guides is provided with a slide member that can be slidably fixed to the vertical guide independently, and each slide member is equipped with a bearing member for the rotary blade.

C) Of these, the bearing member of one vertical guide portion is immovable in the axial direction with respect to the shaft of the rotary blade, and the bearing member of the other vertical guide portion is relative to the shaft or the sliding member.
It is equipped so that it can move in the axial direction.

D) Further, each bearing member is of a tiltable type with respect to the shaft or the sliding member.

In this device, the axis of the rotary blade is from horizontal to 15
Even if it is provided so as to be inclined by about ± °, or that the structure in which the axis of the rotary blade is originally inclined at 45 ° to 60 ° with respect to the horizontal plane can be changed by ± 15 ° with respect to this, Included in the range.

(Operation) In the present invention configured as described above, when the axis of the rotary blade is a reference angle, for example, when the horizontal is the reference angle, the two slider members are moved so that their heights are the same. Equally, adjust the position of the circumference of the rotary blade to the depth to be cut. Next, the guide member provided on the horizontal guide member at the position perpendicular to the conveying direction between the pair of belt conveyors is guided by the horizontal guide member and slid to the optimum position according to the size of the fish to be cut or incised. Fix it.

When tilting the rotary blade, the shaft generally tilts the mounted end of the rotary blade to the highest position and the other end to the lower position. It should be noted that the reverse may occur in the case of special processing.

That is, the slide member farther from the rotary blade is lowered along the vertical guide portion. In this way, the shaft of the rotary blade is tilted because the slider member closer to the rotary blade is in the original position, and accordingly, the bearing member mounted on each member is tilted (bearing member). When is the self-aligning type, only the inner ring of the bearing member tilts) and the dimension between the two bearing members expands slightly, so the bearing member farther from the rotary blade moves axially and axially again. Since the member and the shaft are equipped so as not to move in the axial direction, the bearing member and the shaft closer to the rotary blade are in the axial direction,
It slides by the variable dimension of the bearing member spacing.

Therefore, if it is determined whether the position of the circumferential edge of the rotary blade is appropriate, and if it is inappropriate, the two bearing members have the same dimension in the same direction when finely adjusting the movable frame or changing the depth of cut. Move up or down, fix them with appropriate clamps, and run.

In the case where the axis of the rotary blade is originally inclined at the reference angle, the same operation as above is performed at an angle near the reference angle.

In such a device having a pair of left and right rotary blades, the same operation is performed for the left and right rotary blades. If there are several sets of rotary blades in one device, the same operation is performed for all rotary blades.

In this way, the fish cutting device with the rotary blade adjusted is operated, and if the target fish of which the fish species and the size are selected in advance are sequentially supplied between the pair of belt conveyors, the inclination angle and the position are adjusted respectively. It is cut or incised by a fish rotary blade.

(Effect) In this invention, which is constructed and acts as above, two bearing members are supported for the cutting angle and position of the rotary blade according to the difference in fish species, size of fish, difference in skeleton, etc. It can be adjusted by the vertical movement of the sliding member and the movement of the movable frame. In particular, one of the two bearing members is fixed to the shaft so as not to move in the axial direction, and the other is slidable, so that the shaft is fixed so as not to move in the axial direction. There is no risk that the position of the rotary blade will change significantly during tilt angle adjustment because it tilts based on the position.Since the other bearing members are slidable in the axial direction with the shaft, there is a gap between the two bearing members due to the tilt of the shaft. It follows the dimensional displacement of and does not give any distortion to the shaft.

In addition, since the structure is simple, there are few failures, the cost of the device is low, and the adjustment work is easy, so the setup time is shortened, the operating efficiency of the device is improved, and the overall fish processing cost is less affected. .

Equipped.

The structure of one embodiment of the tilt angle and cutting position changing mechanism 15 is as follows.

A guide member 17 which is horizontal at a right angle to the conveying direction of the belt conveyor 12 is fixedly provided in a part of the machine frame 16 of the fish cutting device 10.
The horizontal guide member 17 and the movable member 18 which can be slidably fixed have vertical guide portions 19 and 20 at two positions near and slightly apart from the conveyor of the belt conveyor 12 in a direction perpendicular to the conveying direction. They are provided side by side, and the distance between these two vertical guide portions 19 and 20 is set to about 20 to 40 cm, but this numerical value itself has no limiting meaning. A rack 21 extending further in the movable direction is fixed to the movable member 18, meshes with a pinion 22 equipped on the machine frame 16, and is fixed to one end of a shaft 23 of the pinion 22. The movable member 18 can be slid along the horizontal guide member 17 by a horizontal moving handle 24, and can be fixed at an arbitrary position by an appropriate clamp 25 such as a set screw.

Each of these vertical guides 19 and 20 is provided with a slide member 26 or 27 that can move horizontally along the vertical guide portion 19, and a bearing member 28 or 29 for supporting the shaft 14 of the rotary blade 13 is provided. It is equipped on the slide members 26 and 27, and in the example shown,
Each bearing member 28, 29 is tiltably mounted on a corresponding slide member 26, 27 by a horizontal axis 30, 31 diametrically of the shaft 14.

Further, of the two bearing members 28, 29, the bearing member 29 farther from the belt conveyor 12 is provided so as not to move in the axial direction with respect to the shaft 14, and the other bearing member 28 is provided with the shaft 14. On the other hand, it is equipped with a sliding key, a spline, etc. that can slide in the axial direction.

Each of the vertical guide portions 19 and 20 is equipped with a feed screw rod 32 or 33 of the same shape and the same size in parallel with the guide direction, and the feed screw rods 32 and 33 are provided with the slide member 26 or 27 is screwed, and the handle 34 at the upper end of the feed screw rods 32, 33,
The sliding members 26, 27 and the bearing members 28, 29 can be independently moved up and down by 35, and these can also be clamped to the vertical guide portions 19, 20 at arbitrary positions, for example, the respective feed screw rods 32, 33. Female thread 3 screwed onto
It can be positioned and fixed at any height by 7, 38.

The shaft 14 of the rotary blade 13 is an intermediate transmission shaft 40 by a motor 39,
Suitable transmission means, in the example shown, pulley groups 41, 42 and 4
It is rotationally driven through the endless belt groups 45 and 46.

As a mechanism for tiltably supporting the bearing members 28 and 29 with respect to the above-mentioned slide members 26 and 27, if the above-mentioned bearing members 28 and 29 themselves are self-centering type (see FIG. 5), The inner rings 28a and 29a can be tilted together with the shaft 14 within a permissible range, and this invention falls within the concept of a tiltable bearing.

Others have shown that the rotary blade 13 can be tilted at an angle within a range of up to a little (about 15 °) from the place where the rotary surface of the rotary blade 13 is almost vertical, but the tilt angle of the rotary blade 13 is originally a vertical line. On the other hand, when the position inclined by about 45 ° to 60 ° is the reference position, the vertical guide portions 19, 20 and the feed screw rods 32, 33 are provided.
Even if the respective angles are also inclined correspondingly, those guide parts are included in the concept of the vertical guide parts 19, 20.

(Operation of Embodiment) In the embodiment configured as described above, in addition to the operation and effect of the present invention, the axis of each rotary blade 13
14 is supported by the above-mentioned bearing members 28 and 29 at two places where they are slightly separated from each other.
Since 28 and 29 are supported by slide members 26 and 27 that can be fixed to slide vertically, it is possible to change the position up and down while keeping the inclination angle of the shaft 14 as it is. The tilt angle can be adjusted to the optimum position, and this adjustment itself is the feed screw rod 32,
Fine adjustment is possible by 33, and after setting, the clamp consisting of female screws 37, 38 screwed into the screw rods 32, 33 is a movable member.
By tightening to 18, the positions of the bearing members 26, 27 are fixed during the rotation of the rotary blade 13 thereafter.

Although the dimension between the two bearing members 28 and 29 is slightly changed due to the inclination of the shaft 14, one bearing member 28 and the shaft 14 are provided so as to be slidable in the axial direction. Relative axis
Move in 14 axial directions.

On the other hand, since the bearing member 29 is mounted so as not to move in the axial direction, the shaft 14 and the rotary blade 13 incline with respect to the bearing member 29. Therefore, the axial position of the shaft 14 is changed by changing the inclination angle. Does not happen.

Further, by rotating the handle 24 at the upper end of the pinion shaft 23 to the left or right, the pinion 22 fixed to this pinion shaft 23 and supported by the machine frame 16 is rotated and meshed with this. The rack 21 and the movable member 18 integral therewith can be moved and adjusted along the horizontal guide member 17 in the direction perpendicular to the conveying direction of the belt conveyor 12, and the position of the rotary blade 13 can be adjusted to move in the direction orthogonal to the conveying direction. After the adjustment, the movable member 18 is fixed to the machine frame by the clamp screw 25 provided on the machine frame 16.

(Effect of Embodiment) In this embodiment, which can be constructed and used as described above,
In addition to the effect of the present invention, the tilt angle and notch position changing mechanism 15 is as described above. Therefore, in order to change the tilt angle of the rotary blade 13, the handles 34, 35 at the upper ends of the feed screw rods 32, 33 can be changed.
By rotating either one of them, the feed screw rod 32 or 33 is rotated around its axis, and the slide member 26 or 27 equipped with the bearing member 2829 screwed with this is moved up or down. The tilt angle of the rotary blade 13 can be easily adjusted by moving the rotary blade 13 to.

To move only the vertical position without changing the inclination angle of the rotary blade 13, the handles 34 and 35 can be rotated in the same direction by the same rotation angle.

Also, without changing the inclination angle and cutting depth of the rotary blade 13,
In order to move the rotary blade 13 in the direction perpendicular to the carrying direction, the handle 24 at the upper end of the pinion shaft 23 is rotated, the pinion 22 is rotated, and the movable member 18 via the rack 21 meshing with this.
Can be performed by moving the belt conveyor 12 close to or away from the conveyor.

Thus, the fixing after the adjustment can be easily clamped by tightening the push screw 25 and the female screws 37 and 38.

Especially when changing the inclination angle of the shaft 14 and the rotary blade 13, the bearing member 28,
29 is inclined, but the bearing members 28 and 29 are both slidable members 26 and 27.
Pivoting around a horizontal axis 30, 31, or bearing member
28 and 29 themselves are self-aligning type and one bearing member 28
Since only the shaft 14 and the shaft 14 are movable in the axial direction, the inclination angle changing operation can be smoothly performed without any obstacle.

Further, the overall structure is simple, no failure occurs, maintenance is easy, and the manufacturing cost of the device is not increased.
