Abstract

PURPOSE:To increase the detection precision, by connecting right/left paired conveyance chains to each other by a continuous-connection member, and providing support bases for supporting fruit-receivers or the like on the right/left side portions of the continuous-connection member. CONSTITUTION:L-shaped outer plates 11, 11 are provided to paired right/left conveyance chains 1, 1, respectively, and a connection member 2 is disposed, at its opposite ends, on right/left opposing bent portions thereof to be bridged therebetween and mounted by being fastened by, for example, a bolt/nut fastener, thereby connecting the paired right/left chains 1, 1 together. And support bases 4, 4 are removably mounted on the bent portions of the continuous- connection member 2, respectively. On these support bases, hollow cushion members 12 are disposed, respectively, at a substantially central parts thereof in a state wherein they are continuously connected to the support bases 4. In addition, fruit receivers 3 are provided turnably by support arms 13. This construction prevents twisting of the conveyance chains 1, 1 and also prevents erroneous detection.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a conveying device for fruits, etc.

(Prior Art) Conventionally, in a conveying device consisting of two rows on both the left and right sides, receivers are individually provided in the transfer chains on both the left and right sides to load fruits, transport them to a predetermined position, and then discharge the fruits. Met.

(Problem to be Solved by the Invention) Fruits loaded on a receiver such as a saucer supported by supports attached to the left and right transfer chains are transported by the rotational drive of the transfer chain, and during the transfer, for example, By passing through the detection device section, the objects are sorted by grade or class by this detection device.

The fruit is transported to a predetermined classification position, the tray is rotated, and the fruit is discharged.

During this transfer operation, the transfer chain may be twisted due to the load of the fruit, and this twist may cause the tray or other receiver to be tilted, causing the loaded fruit to be transferred in an inclined state, for example. Detection by size becomes inaccurate, or
It had drawbacks such as rolling.

(Means for Solving the Problems) The present invention connects the transfer chains 1, 1, which move at the same speed at appropriate intervals on both the left and right sides, with a connecting member 2, and the connecting member 2 has A saucer for loading fruits (A), etc., transporting them to a predetermined position, and discharging the fruits (A) 3.
Alternatively, the structure of the apparatus for conveying fruits, etc. is characterized in that a support stand 4 for supporting a receiver such as a receiving plate is provided.

(Function of the invention) A connecting member 2 connects the left and right transfer channels 21 and 1. Fruits (i.e. ) are being transferred by the rotational drive of the transfer chains 1, 1, and during the transfer, for example, they pass through a detection device, where they are sorted by size and grade, and transferred to a predetermined classification position. Then, the saucer 3 rotates and the fruit (a) is evacuated.

(Effects of the Invention) According to the present invention, by connecting the left and right transfer chains 21, 1 with the connecting member 2, twisting of the transfer chains 1, 1 caused by the loading load of fruit (A) can be prevented. As a result, the third tray and other receivers are no longer tilted, and as a result, the fruit (A) is no longer transferred in an inclined state, which reduces the number of false detections a by the detection device and improves sorting. Performance has been improved.

(Example) Hereinafter, one embodiment of the present invention will be described based on the drawings.

Turning indicates the conveying device 5 that sorts the fruits (A) according to size while conveying them.

The transition part of this conveying device 5 includes a front end drive shaft 7 of the frame body 6,
A rear-end driven shaft 9, a drive sprocket 8°8 of the same diameter disposed on the drive shaft 7 at an appropriate interval, a driven sprocket 10 similarly disposed on the driven shaft 9 at an appropriate interval,
10. The drive sprockets 8, 8 and the driven sprockets 10, 10 are connected by a transfer chain 1, 1, etc., which is connected to a pulley provided on the drive shaft 7 and the frame 6. The boot I and the hook provided on the upper motor 10' are configured to be rotationally driven via a belt passed therethrough.

The transfer chains 1, 1 are provided with outer plates 11.11 bent in an L-shape at predetermined intervals, and the connecting members 2 are tightened with bolts and nuts so that the left and right opposing bent portions are connected in a bridge shape. Fixed. Further, on the bent portion of the connecting member 2, a support base 4.4 is constructed so as to be freely attachable and detachable using the bolts and nuts.

A hollow cushion member 12 is provided on each of the left and right support stands 4, 4 at approximately the center in the vertical direction so as to connect the support stands 4, 4. A saucer 3 is provided on the top of the fruit (A) as a receiver for receiving the fruit (A). That is, on the back side of this saucer 3, support arms 13, 13 projecting downward are rotatably supported by a rotation shaft 14.

Further, the support arm 13 is connected to the support arm 13 by a fixing pin 15 protruding from the end thereof, and when the saucer 3 maintains a horizontal position, the lower end is in contact with the cushion member 12, and the support arm 13 The lower end of 13° is configured to bounce.

Locking hooks 16 are provided on the left and right support stands 4, 4.
is rotatably supported by a lock shaft 17, and when the saucer 3 is held in the horizontal position, the central locking portion 16' on the upper surface of the locking hook 16 engages with the fixing pin 15.
The saucer 3 is in the hooked state and the lower surface is in contact with the cushion member 12 as described above.
can maintain a horizontal position.

When the end of the locking hook 16 is pushed by the excitation of a solenoid (not shown), the hooked state is released and the locking hook 16 rotates (phantom line in FIG. 3).

This rotation allows the saucer 3 to rotate about the rotation shaft 14 as a rotation center.

The upper surface of the saucer 3 on which the fruits (A) are loaded has a planar shape, and is formed by covering the upper surface with a saucer cover 19, which is made of a predetermined material such as rubber or resin. The hardness of the protrusions 18 is gradually softened at predetermined intervals from the outer side toward the center. The structure is such that the fruit (A) is supplied from a container (not shown).

Instead of the receiving plate 3, narrow slat-shaped receiving plates 23.23 may be arranged in a continuous manner to form a series of conveyor surfaces (FIG. 4).

A sorting device 20 is provided at a predetermined position of the frame 6 of the conveyance device 5 to sort the fruits (A) loaded onto the tray 3 and being transferred into grades according to size. The sorting device 20 is configured to use an upper light emitting element 21 and a lower light receiving element 22 to output a signal for sorting fruits (A) into L class, ordinary M class, and small 8 class according to size, and outputs a signal based on the detection results. Accordingly, the solenoids are energized to discharge to predetermined positions according to the L class, M class, and S class.

Hereinafter, the operation of the above embodiment will be explained.

By rotating the two rows of transfer chains 1.1 connected by the connecting member 2, the fruit (A) is transferred from the feeding device onto each saucer 3 attached to the transfer chains 1, 1 via each support stand 4. The fruits (A) supplied and loaded onto each saucer 3 are transferred and passed through the sorting device 20 section, and are sorted by size by the light emitting element 21 and light receiving element 22 of this sorting device 20, When the tray 3 is moved to the predetermined position for each grade, the corresponding solenoid is energized, the locking hook 16 is pushed, the hooked state to the fixing pin 15 is released, and the saucer 3 is moved downward around the rotating shaft 14. By rotating, the fruit (A) on this receiving surface is discharged at a predetermined discharge position.
