Description

[Detailed Description of the Invention] The present invention relates to a fruit sorting machine that sorts as many spherical and oval fruits and vegetables as possible within a unit time by accurately measuring the outside diameter.

The purpose of this invention is to hold a rectangular saucer horizontally in the grading supply section and tilt it at an angle of approximately 30' in the grade sorting process, while an external tray is attached to the top of the tray mount to which the tray is attached so that it can be tilted upward. A frame is attached, an vertical fruit sorting plate is attached inside the tip, and a roller is attached to the outer edge of the frame, and the outer frame is always open upwards because the mounting shaft is covered with a torsion coil spring. Although it is elastically loaded so that it is in the state of It is an object of the present invention to provide a shaped fruit sorting machine in which guide grooves are provided in the saucer and the fruit sorting plate so that the fruit sorter can linearly roll and slide.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 in the figure represents an endless conveyor chain, on which a large number of tray mounting stands 2a are attached at equal intervals.

Reference numeral 2 denotes two upper and lower hinges provided on a portion rising up on one side of the saucer mount and extending upward.

3 is a rectangular saucer attached to the lower hinge, on which spherical fruit selections are placed side by side according to the input.

Reference numeral 4 denotes a protective film made of urethane rubber or the like pasted on the inside of the saucer 3, and is shaped into a concave surface to prevent damage to the item and at the same time to facilitate positioning of the object to be measured on the center line.

Reference numeral 5 denotes a running wheel attached to the lower part of the saucer 3. The saucer 3 is held horizontally by the running rail 6 and runs.If the rail tilts diagonally downward while traveling, the saucer 3 is centered around the hinge part of the saucer mounting base 2a. It can be tilted approximately 30 degrees.

Further, the outer frame 7 is attached to a hinge above the hinge to which the saucer 3 is attached, and can be tilted back and forth by 30 degrees around the hinge.

Reference numeral 8 denotes a roller attached to the outer side of the tip of the outer frame 7, and another guide rail 12 that presses the roller 8 moves up and down to raise and lower the fruit sorting plate 9, which has an elevated surface on the inner side of the tip of the outer frame.

Reference numeral 10 denotes a cushioning material adhered to the inner surface of the fruit sorting board 9, which forms a transfer groove and serves to prevent damage when the products roll and slide.

Reference numeral 11 denotes a torsion coil spring, which is attached to the rotating hinge pin of the outer frame 7 and has the function of constantly rotating the outer frame 7 upward.

Reference numeral 12 denotes a guide rail for adjusting the opening/closing degree of the outer frame, which is divided into sections at regular intervals, and is adjusted by a minute adjustment screw 16 on the mounting portion.

13 is a guide rail mounting bracket, 14 is a chain rail, 1
5 indicates the main frame.

Reference numeral 16 is a fine adjustment screw that gradually opens the fruit sorting plate, and adjusts the position (height) of the guide rail 12 so that the selected fruits discharged from the tray have an appropriate size at each stage.

Compared to conventional machines of the same type, the shaped fruit sorting machine according to the present invention has a saucer and a fruit sorting plate attached to a chain attachment using the same saucer mounting base, so the fruit sorting plate is attached to a separate traveling chain. It produces far less vibration than a machine, has far superior accuracy in measuring outer diameter dimensions, has a simple structure, and is inexpensive to manufacture.

The fruits and vegetables roll almost along the center line and slide against the cushioning material lining the saucer and the cushioning material sorting board, so that the spherical fruits and vegetables can be placed in various positions (
Compared to conventional machines that measure by position (posture), the measurement dimensions are significantly more accurate, the beads are well aligned, and the product value is high.In addition, it saves labor when manually inserting into packs, etc., and allows packaging work with less damage to the goods. There are advantages to doing so.

Claims (1)

[Scope of utility model registration request] A one- or two-strand conveyor chain that runs and rotates endlessly is provided with saucer mounts at regular intervals, and two upper and lower hinges are provided on the part that stands up on one side of the tray mount and extends upward. The upper hinge is equipped with a saucer that can be tilted downward from horizontal to the other side and has its tip side open, and the upper hinge is equipped with an outer frame that surrounds the outer periphery of the saucer and can be tilted from horizontal to upward. A running wheel is provided at the bottom of the saucer to support the saucer horizontally and slopingly while running on a running rail, and an elevation is formed on the inside of the tip of the outer frame so as to close the open tip of the saucer, and the tray is placed on the outside. The shape is such that rollers are attached and guide rails support the horizontal and inclined outer frame, or the tip of the saucer and the vertical position of the outer frame are adjusted by gradually tilting the outer frame upward during the process of the saucer moving downwardly. The feature is that the gap formed between the bottom side of the face and the bottom side is enlarged stepwise or steplessly, and the selected fruits of a size corresponding to the gap are rolled onto the receiving box and discharged from the gap.
