Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a centering and gripping device for bulbous vegetables, fruits, etc., which is applied to a cutting device for cutting the leaf and root portions of onions, a device for coring apples, and the like.

(Prior Art) Conventional cutting of leaf and root parts, which is done prior to chopping onions, does not have an effective centering device.
First, the centering is performed manually and the material is placed in the gripping device.
Currently, the leaf and root parts are cut using a cutting device.

(Problem to be Solved by the Invention) In other words, in conventional devices of this kind, the cutting section is mechanized to prevent uneven cutting and save labor, but the cutting section does not cut vegetables such as onions or apples. - When feeding fruit, centering is done manually to ensure proper orientation to the knife, and labor-saving efforts in this process have not been achieved.

Therefore, in the work of cutting the seed-leafed part and the rooted part, etc., the centering work limits the processing capacity, so the merits of mechanization are not currently fully utilized.

Therefore, an object of the present invention is to develop an apparatus that can automatically center onions and the like and automatically feed them to a cutting section.

(Means for Solving the Problem) In order to achieve the above object, the present invention provides a rotating member for placing bulbous vegetables, fruits, etc., which has a self-propelled surface such as a cylindrical drum or a belt conveyor, and a self-propelled member for placing the rotary member. A pair of gripping members having opposing gripping surfaces in the shape of an inverted cone, which are disposed at a predetermined distance from the running surface and move toward and away from each other at right angles to the self-running direction. A centering and grasping device for fruits, etc. is adopted as a component.

(Operation) When onions, etc. are transferred on a rotating cylindrical drum or a self-propelled surface such as a belt conveyor, the onions rotate around an axis of rotation that almost coincides with the axis that connects the leaf and netsuke.In this state, the inverted conical grip When a pair of gripping members having surfaces are brought closer to the leaf and netsuke parts, the parts are warped inward along the opposing gripping surfaces, and are finally gripped in a centered state. become.

(Example) Hereinafter, the present invention will be specifically explained using an illustrated example apparatus in which the present invention is applied to an onion cutting apparatus.

The figures all relate to the device of this embodiment; FIG. 1 is a side view of the same device, FIG. 2 is a plan view of the same, and FIG. 3 is a sectional view taken along line A--A shown in FIG. 2.

In these figures, the drum 1 is rotatably mounted on a base 29 via bearings 2 and 3, and the shaft of one of the three bearings is connected to the shaft of an electric motor 5 by a shaft coupling 4.

A pair of brackets 8 and 9 are provided on the upper part of the drum 1 and extend horizontally to both ends of the drum, perpendicular to the drum 1, and the base ends of each bracket 8 and 9 are fixed on a base 29.

A pair of rotating rollers 6 and 7 are attached to the brackets 8 and 9 in parallel to the rotational axis of the drum 1, which are divided into the front and rear with the uppermost surface of the drum 1 in between. Furthermore, one spline shaft 14 is rotatably attached to the opposite end of each bracket 8.9 to the drum.
It is connected to 0. Further, on the spline shaft l4, there are a pair of arm members 31 and 3 whose one end extends above the drum 1.
2 is spline-coupled to the spline shaft 14 via nuts 15 and 16, respectively, and is attached so as to be slidable in the axial direction and rotatable together with the spline shaft 14. These arm members 3l and 32 are connected to one long link 12 via short links 10 and 11.
The long link 12 is connected to the spline shaft l.
It is rotatably supported within a horizontal plane at the center of a block 13 fixed at the center of the block 4. Furthermore, a fixing member 33 is fixed to one end of the spline shaft 14 , and a pneumatic actuator 17 is fixed to this fixing member 33 , and a driving rod of the actuator 17 is fixed to one arm member 32 . Gripping members a and b are attached to opposing ends of the pair of arm members 31 and 32 on the drum side, at the uppermost surface of the drum.

As shown in FIG. 3, this gripping member is rotatably attached to arm members 31, 32 via bearings 22 and 26, respectively, and its gripping surface is shaped like an inverted cone 21, 25.

In addition, 18.19 in the figure is a frame, 23, 24, 27.28
indicates a retaining ring.

Next, the operation will be explained with reference to FIGS. 4 and 5. When the drum 1 is being rotated by the electric motor 5, as shown in FIG. When one onion B is put between a and b, onion B starts to rotate due to the rotation of drum l, and after a certain period of time, as shown in Figure 4, the axis passing through the leaf and netsuke parts will change. It rotates almost parallel to the rotation axis of the drum l.

In this state, when the gripping members a and b, which have approximately conical recesses, move to grasp the onion B, the onion B has its leaf and root parts inside the recesses of the gripping members a and b, respectively. be grasped.

The movement of the arm members 31 and 32 at this time is performed by the operation of the pneumatic actuator l7, and each link 10.11.12
They move in sync to ensure center distribution.

That is, by pushing out the rod of the pneumatic actuator 17, the arm members 31, 32 move closer to each other,
Grasp onion B. At this time, the leaf portion and the root portion fit into the respective recesses of the gripping members a and b, thereby further stabilizing centering.

In this state, the swing drive machine 20 is operated to rotate the spline shaft l.
4, the arm members 31 and 32 are rotated to take out the onion B, the rond of the pneumatic actuator 17 is pulled in to release the grip on the onion B, and the onion B is transferred to the next step (not shown) in that position.

(Effects of the Invention) As described above in detail, according to the present invention, by simply placing bulbous vegetables, fruits, etc. on a self-propelled surface, centering and gripping can be performed automatically. This makes it possible to automate centering, which has been a bottleneck, and enables full automation in this type of cutting machine.
