Description

[Detailed Description of the Invention] The present invention relates to a partition between the bucket trays of a towed sliding type fruit sorter, and a device for buffering the rolling impact of the bucket trays in the driving and driven parts.

Conventionally, this type of fruit sorting machine has a structure in which the bucket is attached to the connecting fitting of the conveyor chain using a holder so that the bucket can rotate freely from a horizontal position to a vertical position. When rolling from the front to the inside out or from the inside out to the front, the turn section rail that receives the protruding piece provided on the side of the bucket or the rotating disk that receives the bottom of the bucket is attached concentrically to the drive driven shaft. However, each time the center of gravity of the bucket with respect to the fulcrum of the holder moves, the bucket hits the guide rail or the connecting fitting side, and the impact generates vibrations. However, there was a drawback that the measurement accuracy was affected. Furthermore, there is a drawback that noise is generated due to the contact between the bucket and the rail or the connecting fittings, which causes discomfort to the operator and reduces work efficiency.

In addition, when the selected fruits are fed and supplied using a bucket conveyor having a plurality of rows of buckets, an arch is provided in a part of the frame in the supply section, and a partition member is inserted between the rows of buckets from this arch. The structure is designed to prevent the fruits to be hung and thrown into the buckets from rolling out between the buckets and the rows of buckets, but since these partition members and arches are fixed to the feeding supply section, The disadvantage was that the arch created a dead space in the working area, making the aircraft longer. Furthermore, since the partition member is fixed as the bucket advances, there is a drawback that the selected fruits that are about to come out of the bucket may be scratched.

The present invention has been made to solve the above-mentioned drawbacks, and includes a connecting member that connects the front and rear connecting fittings above a protruding piece such as a pin or a tongue protruding from the side of the bucket. The lower surface of the connecting member receives the protruding piece and prevents shock and noise caused by the contact of the bucket when the bucket rolls from front to inside out or from inside out to front in the driving part and driven part of the bucket conveyor. Furthermore, the upper surface of this connecting member is extended above the upper surface of the saucer to the side of the saucer so that it doubles as a partition member between the rows of buckets.This design was selected because the impact vibration and noise of the bucket are small, and the loading operation is easy to perform. The purpose is to provide a towed sliding type fruit sorting machine that can sort fruits with high precision without damaging them.

4 to 9 showing embodiments of the present invention will be explained below.

The fruit sorting machine frame 1 is a conveyor chain, and two conveyor chains are endlessly stretched from a driving sprocket 3 to a driven sprocket 4 at a predetermined interval. A chain receiving rail 5 is attached to a part of the frame and allows the chain 1 to run horizontally. Reference numeral 6 denotes a connecting fitting in which two chains 1 are connected in large numbers at equal intervals, and the connecting fitting serves as the attachment part of the bucket belt 7 to the conveyor. (Number of threads) The lengths are set according to the width of each machine. The bucket 7 is attached to the connecting fitting 6 so as to be able to freely rotate downward from a horizontal position to a vertical position using a bucket holder 9 connected with a fulcrum pin 8, and the selected fruits are placed on the tray 7a of the bucket 7. When the bucket cart 7 is carried on the vehicle, a protruding piece 10 such as a pin or a tongue protruding from the side of the bucket cart 7 is received from below by a traveling rail 11 to hold the bucket cart 7 horizontally and convey it. In order to discharge selected fruits from the bucket for each sorting class during a long conveyance process, a discharge switching device is provided on a part of the running rail to switch the running path of the protruding piece 10 and rotate the bucket downward. A semi-circular turn section rail that is connected to the traveling rail and receives the protruding piece 10 in the driving rotation section; Alternatively, it is conventional that the rotary disk 12, which receives the bottom of the bucket, is attached to the drive shaft coaxially with the sprocket 3 and guided.

Reference numeral 13 denotes a connecting member in the traveling direction, which is a main part of the present invention, and includes a protruding piece 1 that protrudes to the side of the bucket bag 7.
0 and on the side of the saucer 7a, the front and rear connecting fittings 6
It is installed so that the parts are connected in the advancing direction (vertical direction), and there is a member that can be expanded, contracted, and bent so that there is no problem even if the pitch (installation length) is different between the straight running part and the rotating part of the sprockets 3 and 4. Various shapes are used, such as a link shape (Fig. 10), a band shape, a belt shape (Fig. 5), or a chain shape, but preferably one made of a material with some elasticity is used. It is highly effective in preventing noise. The lower surface of the traveling direction connecting member 13 is connected to the bucket belt 7 at the rotating part of the conveyor tip sprocket 3.
is turned over from the front side, passes through the turned side, and receives the protruding piece 10 of the bucket belt in the rotating part of the driven sprocket 4 in the driven section until the bucket belt 7 is turned face up. is designed so that it does not swing laterally even when expanded, contracted, or bent. By providing the connecting member 13 in the traveling direction between the connecting fittings as described above, when the bucket cart 7 rotates in the drive section and the driven section, the bucket mounting surface 6a of the connecting fitting 6 is connected to the sprockets 3 and 4 as shown in FIG. The rotatable bucket when the connection line A is oriented with respect to the circle is the bucket holder 9.
When the center of gravity shifts outward with respect to the fulcrum pin 8,
In order to prevent the bucket from protruding outward to a position along the tangent line A, causing flapping and causing vibration to the chain, a straight line B connecting the arcs is formed to restrict the outward protrusion of the bucket, thereby preventing flapping and vibration, and at the same time reducing noise. This was done to prevent this from occurring.

The present invention further provides an upper surface 13a of the connecting member 13 in the traveling direction above the tray 7a of the bucket 7 to serve as a partition between the rows of buckets, that is, to prevent selected fruits from rolling out from the tray 7a when being fed. It was constructed to act like a jetty between the rows of buckets.

As described above, this invention was able to prevent the vibration of the bucket chain conveyor, improving the accuracy of measurement and sorting, which is important for a fruit sorting machine, and also by attaching a partition member between the bucket rows to the conveyor. The performance of the fruit sorting machine could be greatly improved since no scratches were caused to the selected fruits in the input and supply section.

Furthermore, the fluttering noise of the bucket has been significantly reduced, and the arch for suspending the partition in the input and supply section has been removed, making it easier for workers to use.
