Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting apparatus for fruits and the like, and can be used in a fruit transfer sorting line such as a fruit sorting machine or a fruit sorting facility.

[0002]

2. Description of the Related Art As disclosed in Japanese Patent Laid-Open No. 55-114378, a weighing tray provided on a mounting frame is overturned,
In the equipment to be restored, the shaft support of the weighing pan is selectively pivotally supported by the pivot on either the left or right side of the support on the side of the mounting frame. A configuration that can be used in common is known.

[0003]

However, in the above configuration, it is necessary to selectively switch the pivots,
It is very troublesome.

[0004]

The present invention has been proposed to solve the above-mentioned drawbacks, and has taken the following technical means. That is, the attachment member 9 is fixed to the pair of left and right endless chains 8 provided along the transfer direction, and the attachment members 9 are pivotally supported by the front ends of the links 10 and 10. An elevating member 12 for supporting the fruit tray 2 is attached to the rear end, and when the elevating member 12 descends, the lower surface of the fruit tray 2 comes into contact with the convex portion 19 provided on the mounting member 9 to rotate the fruit tray 2. A support shaft switching body 5 that is configured to tilt in either the left or right direction around the support shaft 3 or 4 and selects the rotation support shaft 3 or 4 of the fruit tray 2 to select the rotation direction. Is provided, and the support shaft switching body 5 is configured so as to be switched by sliding contact with the guide members 6 and 7 provided in the transfer path.

[0005]

The saucer 2 for fruits or the like can be selectively tilted from the left side to the right side based on the switching movement of the support shaft switching body 5, and when the saucer 2 is installed, like the conventional device, the falling direction It is not necessary to decide and assemble the product, which facilitates the work.

[0006]

Embodiments of the present invention will be described with reference to the drawings.
Endless chains 8 and 8 are arranged on both the left and right sides along the transfer path 1, and mounting members 9 are fixedly connected between the chains 8 and 8 at regular front and rear intervals. Up and down parallel links 10 and 10 are connected to both sides via pivots 11 and 11 so as to be vertically rotatable toward the rear.

At the rear ends of the parallel links 10 and 10, an elevating member 12 for supporting a tray 2 which will be described later is rotatably attached via pivotal support portions 13 and 13. The fruit tray 2 is provided on the upper end of the elevating member 12 via the spindle switching body 5, and the sliding contact pin 14 is provided on the lower end toward one side in the left-right direction.
Is protruding. Front and rear L-shaped support shaft guide grooves 15 and 16 having open upper ends are symmetrically provided on both left and right sides of the support shaft switching body 5, and these guide grooves 15 and 16 guide the left and right side parts of the elevating member 12. Between the surfaces 17 and 17, the opening of the guide groove 15 is closed by the guide surface 17 at the position where the support shaft switching body 5 is moved to the left side, and the guide groove 17 closes the left side of the fruit tray 2 in the guide groove 15. The support shaft 3 is configured to be rotatable, and at the same time, the opening is opened in the guide groove 16 on the right side, and the support shaft 4 on the right side fitted to this is ready to be removed upward.

On the contrary, when the support shaft switching body 5 is moved to the right side, the guide groove 16 on the right side is closed and the guide groove 15 on the left side is opened. The fruit saucer 2 has a recessed central portion on the upper surface for facilitating the placing of fruits, and the left and right side portions are slightly recessed to facilitate the discharge of the fruits to the left and right sides. At the bottom of the fruit tray 2 is an annular control ring 1
8 is provided, and a regulating projection 19 projecting from the mounting member 9 is fitted therein.

At the transfer end of the transfer path 1, there is provided a supply part for supplying fruit onto the fruit tray 2, and at the intermediate part of the transfer, there are arranged fruit selection receivers on both left and right sides. Is equipped with a weighing device according to the selection. In this measuring device, the measuring operation rod is seen in the middle of the sliding rail of the sliding contact pin 14 provided along the transfer path 1, and the measuring operation rod receives the sliding contact pin 14 to obtain this measured value. When the excess weight is detected, the weighing rod at this position is lowered, the sliding contact pin 14 is lowered, and the fruit tray 2 is turned over.

20 is a rail of the chain 8, 21 is a side frame,
A guide roller 6 and a guide body 7 are provided along the transfer path 1 and located on the side of the starting end of the sorting receiving portion and on the side opposite to the sorting receiving portion which is to be overturned. It is projected to the transfer path 1 side. Further, on the opposite side of the guide rollers 6 and the like, a guide body 23 for slidingly guiding the other end of the spindle switching body 5 guided by these is provided.

The guide roller 6 is located at the start end side of the transfer direction D and is rotatable. A guide body 7 is continuously provided on the transfer direction side, and the guide surface of the guide body 7 is the outside. It is configured to incline inward from the transfer path 1 in sequence.
The guide roller 6 and the guide body 7 are connected to the transfer path 1
On the other hand, when necessary, the fruit tray 2 may be provided so as to be retractable while keeping the transfer timing, and the fruit is fed at the starting end of the transfer path 1 and then weighed by the weighing device, and the guide roller 6 of each sorting unit is used by this weighing. This is convenient when switching and interlocking, etc.

Next, the operation of the above example will be described. By the rotation interlocking of the chain 8, the support shaft switching body 5, the fruit tray 2, the sliding contact pin 14 and the like are transferred in the arrow D direction in FIG. When the fruit is supplied to the upper surface of the fruit tray 2 at the end of the transfer, the sliding contact pin 14 slides on the upper portion of each measuring device during the transfer of the fruit tray 2, but when the corresponding weight to be selected is detected, this position is detected. Then, the support shaft switching body 5 is pushed by the corresponding guide roller 6 to start the switching operation.

Further, it is pushed by the guide member 7 to close the supporting shaft 3 or 4 of the fruit receiving tray 2 on the tipping side in the guide groove 15 or 16, and the sliding contact pin 14 is lowered from the upper surface of the rail. For this reason, the link 10 that has lost this support is lowered with the pivotal support portion 11 as a fulcrum, and the fruit tray 2 is lowered together with the elevating member 12. The lower surface of the tray 2 is pushed up as the descending member 12 descends while coming into contact with the convex portion 19, and the tray 2 uses the support shaft 3 or 4 on the side closed by the guide groove 15 or 16 as a fulcrum. The spindle 4 or 3 on the other side is separated upward from the guide groove 16 or 15, and the fruit tray 2 is tumbled to the side sorting section to discharge the fruit.

After this fall, when the sliding contact pin 14 returns to the rail again, the elevating member 12 and the fruit tray 2 return to their original positions.
