Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roller attachment/detachment structure in a polishing device for fruits, vegetables, etc.

Conventionally, polishing devices for fruits such as mandarin oranges and tomatoes, vegetables, etc. have been constructed by rotating horsehair rollers arranged in parallel so that mandarin oranges, etc. are polished while rolling on top of the rollers. It is not easy to replace the rollers, and the attachment and detachment of the rollers themselves are complicated and prone to wear.

The present invention aims to provide a structure for attaching and detaching rollers in a polishing device for fruits, vegetables, etc., which allows the rollers to be easily attached and detached by a simple operation.

Embodiments of the present invention will be described in detail below based on the drawings.

1 is a machine frame, and a large number of rollers 2 are rotatably installed on the machine frame 1.

The roller 2 is made of sponge, and is configured so that the roughly rectangular roller pieces 2 are sequentially shifted little by little in a constant rotation direction to form a threaded unevenness.

A core hole 3 is provided in the center of the roller 2, and the core hole 3 is formed in a tapered shape.

A bearing 4 that can freely rotate vertically and horizontally is provided on one side of the machine frame 1 via a pedestal 5, and a core shaft 6 is inserted into the bearing 4. A tapered shaft 7 is loosely fitted, and a spring 9 is interposed between a protrusion 8 provided on the tapered shaft 7 and the ball bearing 4 to urge the tapered shaft 7 inward.

The tip of the tapered shaft 7 is fitted into the core hole 3 of the roller 2.

Further, on the other side of the machine frame 1, a bearing 10 which is also rotatable vertically and horizontally is provided via a pedestal 11, and a roller locking shaft 12 is loosely fitted into the bearing 10. The tip of the coaxial shaft 12 forms a tapered shape 13, and the tip of the coaxial shaft 12 is fitted into the tapered core hole 3 on the other side of the roller 2, and the tip of the coaxial shaft 12 is fitted into the tapered core hole 3 on the other side of the roller 2. Protrusion 1
4 is configured to fit into a locking groove 15 formed at the peripheral edge of the core hole 3 of the roller 2.

In the figure, 16 is a gutter provided at the final end of the roller group;
7 is a motor for rotating each roller 2, 1
8 is a sprocket connected to the outer end of the roller locking core shaft 12, 19 is a chain meshed with the sprocket 18, and the chain is interlockingly connected to the motor 17, and the rotation of the chain causes Each roller 2 rotates in a fixed direction.

This invention is constructed as described above, and when removing the roller 2, first remove the roller 2.
is slid in the direction in which the spring 9 is interposed, the tapered shaft 7 moves along with the roller 2 into the core shaft 6.
As a result, the roller locking core shaft 12 comes off from the core hole 3 at the other end of the roller 2, and the roller 2 moves toward each side that is fitted in the core hole 3. The removal work is completed when the rollers are removed from the core shafts 6 and 12, and when replacing them by removing them, first attach the new roller 2 to the core shaft 6 on the spring-inserted side in the opposite order to the above. The core hole 3 of the roller 2 is fitted, and then the roller locking core shaft 12 is fitted into the core hole 3 on the other side of the roller, and the protrusion 14 and the locking groove 15 are engaged. Due to the tapered shape of the core shaft 6 and the roller locking core shaft 12,
The axes of the left and right core holes 3 of the roller 2 can be accurately aligned with each core axle, and each core shaft 6, 12 is connected to bearings 4, 10 that are rotatable vertically and horizontally on both sides of the machine frame. However, the roller 2 can be installed with the shaft center accurately aligned, and the bearings 4 and 10, which are rotatable up and down and left and right, allow the center shafts 6 and 12 to be easily aligned when the roller 2 is installed. The roller 2 can be operated in any direction, making the installation work of the roller 2 easier.

According to this invention, the roller can be easily removed, and when it is attached to the machine frame after being removed, the roller can be attached and installed with a simple operation while accurately aligning the axis. This has the effect of allowing efficient attachment and detachment work.
