Description

[Detailed description of the invention] Industrial application field This invention relates to a fruit sorting conveyor that arranges fruits such as potatoes and mandarin oranges while transporting them, and can be used in fruit sorting facilities.

Problems that the invention aims to solve: In order to transfer a large amount of fruit and feed them to a sorting device, etc., a pair of left and right brush rolls are rotated, and the brush rolls are transferred along the axial direction. However, some of the fruits being transported are lined up close to each other in the left and right direction, and when they are transferred onto a belt conveyor, it is difficult to maintain accurate front-to-back spacing due to rolling of the fruits. , are unstable and difficult to align.

Means for solving the problem This invention sequentially increases the rotational speed from the starting end to the ending end, and along the upper side of a plurality of transfer transfer belts 1, 2, 3, which transfer fruits with fruits placed on their upper surfaces,
On the starting end side of this transfer belt, there is a V-shaped conveyance guide surface 4 with a wider left-right interval on the upper end side than on the lower end at the center of the left and right width, and as it reaches the end side, each vertical The fruit arranging conveyor is provided with guide belts 6, 6 which rotate while sequentially displacing the guide surface 5 in a twisted state.

Function and effect of the invention Inheritance transfer belts 1, 2, 3 and guide belt 6,
6 is rotated and the fruit to be transferred and fed is fed to the starting end of the guide belts 6, 6, and while being pinched and guided between the V-shaped conveyance guide surfaces 4, 4, , 4, the fruit is sequentially placed in the center of the transfer belt 1, and while being guided on both left and right sides by the transfer guide surfaces 4 to 5, the bottom surface is sequentially placed on the transfer belts 1, 2, and 3. This transfer belt 1, 2, 3
Since the rotational speed of each of these is high, a gap is maintained between the fruits before and after each fruit inheritance, and the fruits supplied from the end of the final transfer belt 3 to the sorting device etc. are one piece and one piece. When placed in an aligned state, accurate alignment can be performed.

Furthermore, the guide belts 6, 6 are used to sequentially displace the V-shaped conveyance guide surface 4 to the vertical guide surface 5, but in this case, the axis directions of the support pulleys on both ends are set to be different. The configuration is simple and easy.

However, when the fruit is transferred from the guide surface 4 whose left and right spacing gradually widens to the upper surface of the transfer transfer belts 1, 2, and 3, the fruit that falls to either side of the upper surface of the transfer transfer belt is Due to the difference in transfer speed between the transfer transfer belt and the guide belts 6, 6 that are in sliding contact with the side surfaces of the transfer belt, the transfer belt tries to be transferred to the normal central position while rotating. As the fruits grow larger, the front and back spacing with other fruits is increased to avoid collisions between fruits due to their rotation, and together with the formation of continuous guide surfaces by the above-mentioned guide belts 6, 6 form, damage to the fruit surface can be quickly eliminated. can be moved to its regular position.

Embodiment In the illustrated example, 7 is a machine base, and the transfer belts 1, 2, 3 and the guide belt 6 are each provided on this machine base 7. The transfer belts 1, 2, and 3 are stretched along substantially the same plane, and are configured to interlock with each other by appropriately setting high speeds in that order, and 8 is the drive motor shaft thereof. Reference numeral 9 denotes a roll between the transfer belts 1 and 2, which is rotatably mounted on a shaft. The pair of left and right guide belts 6, 6 are connected to these transfer belts 1,
The pulley 10 at the starting end is provided to be rotated around a V-shaped axis when viewed from the front, and the pulley 11 at the end is stretched symmetrically with respect to the center line of the transport belt 3 in the transport direction. These pulleys 10 are located on both the left and right sides and are rotatable around vertical axes.
By tensioning the flat guide belts 6, 6 over the length of 11, the guide surface 5 is twisted so that the guide surface 4 at the starting end is in a V-shape and the end surface is in a horizontally perpendicular parallel shape. , 5. Reference numeral 12 denotes a hole formed along the center of the transfer belt 3, into which the bottom of the fruit fits and prevents it from rolling laterally.

A feeding device for feeding fruits one by one is shown above the starting ends of the guide belts 6, 6 having such a structure, and the terminal end of the transfer belt 3 is shown above the conveyor of the sorting device.

The transfer belts 1, 2, and 3 are rotated in the same direction,
When the guide belts 6, 6 are rotated in a direction in which the guide surfaces 5, 5 are synchronized with the transport direction of each belt 1, etc., and the fruit is supplied onto the guide surface 4 at the starting end of the guide belt 6, The fruit received between the guide surfaces 4, 4 is transferred to the guide belts 6, 6, and the gap between the guide surfaces 4, 4 is gradually widened. Transfer belt 1
Large-diameter objects that can be received on the upper surface will be received on the upper surface of the transfer belt 1 more slowly, and will be guided along the center portion of the transfer belt 1 while being guided by the guide surface 4, which rotates at a speed that is approximately in synchronization with the transfer belt 1. Then, they are placed and aligned.

While the fruit is being guided by the guiding surfaces 4 to 5, when it is transferred to the transfer belts 1, 2, 3, rolls 9, etc., the posture of the fruit is stabilized by the swinging of these joints. The transfer belt 3 has a hole 1 along the center.
2, the most stable posture can be maintained when the bottom part is fitted into the hole 12, and the belt 3 can be prevented from slipping out to the side. At the same time, since the rotational speed of each belt 1, 2, and 3 is gradually increasing in this order, each belt 1, 2, and
At the 2nd and 3rd transition areas, the front and back spacing between the fruits is maintained large.
