Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer conveyor in a fruit sorting facility.

[0002]

2. Description of the Related Art Japanese Unexamined Utility Model Publication No. 7-948 discloses an arrangement for extracting long vegetables such as cucumbers from a sorting conveyor. This configuration,
By turning the direction of long vegetables by 90 degrees using a 90-degree curve conveyor, the boxing operation in the storage device at the end of the conveyor is facilitated.

However, the sorting conveyor usually has a plurality of unit series arranged in a plurality of series, and in the above-described embodiment, there is a disadvantage that the interval between the series is increased. In addition, workers who carry out work such as packing at the end of the draw-out conveyor are assigned to each of them, but it is not easy to support in the adjacent lateral direction. In other words, since the drawer conveyor is laid down for a long time, it is possible to support when working from back to back, but it is not easy to support beyond the conveyor.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above problems, and has the following technical means. That is, long vegetables are placed horizontally on the bucket of the sorting conveyor with respect to the transfer direction and are sorted and sorted into grades or grades while being transported. In a fruit sorting facility that is dropped and transported to a predetermined vegetable unloading position,
The drawer conveyor in the fruit sorting facility is configured such that the transfer direction of the drawer conveyor is oblique to the transfer direction of the sorting conveyor (Claim 1).

[0005] Further, the transfer direction of the drawer conveyor is set to be opposite to the transfer direction of the selection conveyor.
A curve conveyor for changing the direction is inserted (claim 4), and a pair of 45-degree curve conveyors are inserted so that the transfer direction of the drawer is the same as the transfer direction of the sorting conveyor (claim 4). 5). In addition, the drawing conveyor is divided into a plurality of parts, and the angle of the sorting conveyor with respect to the transfer direction is gradually increased (claim 2), or the drawing conveyor is formed into a belt conveyor and divided into a plurality of parts. In the direction in which the vegetable longitudinal direction does not coincide with the belt pulley axis.

[0006] Further, a box packing process is performed at the vegetable unloading position, and an empty box supply conveyor is disposed so as to pass near each vegetable unloading position.

[0007]

According to the first, fourth or fifth aspect of the present invention, the draw-out conveyors 7 can be installed substantially along the sorting conveyor 1, so that the intervals between the series can be set small when a plurality of series are provided. Can be narrowed. In addition, it is necessary to go back and forth between the vegetable take-out positions to support and carry on different drawer conveyors.However, the work efficiency is reduced because it is possible to go back and forth at the shortest distance without having to go around the end of the drawer conveyor each time. Do not let.

If the draw-out conveyor is divided into a plurality of parts and is provided in a direction which does not coincide with the belt pulley axis at the transfer part, the long vegetables are less likely to stagnate and roll, so that the transfer is smooth. . Further, when the empty box supply conveyor passes in the vicinity of each vegetable unloading position, the removal of empty boxes by the worker is smooth.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. The figure shows a part of a sorting facility for long vegetables such as cucumbers. Cucumbers containing containers are appropriately conveyed to the upper side of the sorting conveyor 1, and in the supply unit 2, the grade workers classify them as excellent or excellent and determine them. Are placed on the buckets 3, 3,.... Sorting conveyors are provided in two sections, one of which
Articles are composed of excellent lines and others are composed of excellent lines.

The cucumbers placed on the buckets 3, 3,... The length and thickness are detected by a known optical sensor 4, and the control unit 5 determines which of the predetermined classes belongs to. In the middle of the sorting conveyor 1, a plurality of sorting units 6, 6,... In the sorting section 6, when a discharge signal is output from the control section 5, a sorting operation section such as a rotary solenoid (not shown) operates to release the bucket 3 from maintaining its horizontal attitude, and to rotate around the horizontal axis by its own weight. The cucumber is moved and dropped on the lower draw-out conveyor 7, 7,... Plane. At this time, the pull-out conveyor 7 may be disposed so as to be gradually inclined downward at the transfer start end side so that the cucumber is taken over by the pull-out conveyor 7 in a substantially transporting posture so as not to roll.

The draw-out conveyor 7 is composed of a plurality of belt conveyors, and the downwardly sloping first conveyor 7a is set so that its transfer direction is obliquely about 10 degrees with respect to the transfer direction of the sorting conveyor 1 in plan view. are doing. Reference numeral 8 denotes a relay conveyor, which connects the subsequent second conveyor 7b. The transfer direction of the second conveyor 7b is the first conveyor 7
a, that is, about 20 degrees with respect to the sorting conveyor 1. That is, the relay conveyor 8
Is configured as a 10-degree curve conveyor.

The drawing conveyors 7, 7 of the same form are constituted respectively for the two sorting conveyors 1, 1 and these two forming one line, and in the example shown, two lines are provided. I have. At the end side of each of the draw-out conveyors 7, 7,..., An up-and-down type filling stand 9, 9,. In this case, the empty cardboard box is maintained at an appropriate height, and the worker packs the manually packed cucumbers into a box. The lifting table 9, 9,... Can move up and down the box mounting surface by a switch operation, can be maintained at a height that is easy for an operator to handle, and can be lowered after the cucumber is stored.

.. And the sorting conveyor 1, the space between the lifting conveyors 9, 9...
0 is set. FIG. 2 shows the intermediate conveyors 8, 8,.
The drawer conveyor 7 includes a first conveyor 7c and a second conveyor 7d, respectively, and each of the transfer direction angles is set to 20 degrees with respect to the transfer direction of the sorting conveyor 1. The first and second conveyors are in the form of a belt conveyor. At the transfer portion, the rear end pulley 11 of the first conveyor 7c and the front end pulley 12 of the second conveyor 7d are provided.
Is moved to the first conveyor 7c of the draw-out conveyor 7 in a posture where the draw-out conveyor 7 is dropped from the sorting conveyor 1 as much as possible. The pulley shaft or the parallel reference line at the transfer portion is crossed (FIG. 4).

FIG. 6 shows still another embodiment, in which a 180-degree curved conveyor 13 is connected to a first conveyor 7e inclined downward and connected to a second conveyor 7f. Therefore, the transfer direction of the draw-out conveyor 7 is opposite to the transfer direction of the sorting conveyor 1. FIG. 7 shows a 45-degree curve conveyor 1 instead of the 180-degree curve conveyor 13 in FIG.
By combining 4 and 15, 7g of the first conveyor
And the second conveyor 7h are in the same direction as the sorting conveyor 1.

The operation of the above example will be described. While visually classifying the cucumber contained and transferred in the container to excellent or excellent grades, the grade worker puts the individual cucumber into the bucket 3 of the near-side superior grade line or the superior grade line attached thereto in the direction of transport. One by one. The sorting conveyor 1 transfers the cucumbers of the buckets 3, 3,... To the lower side, and is sorted in the middle. The control unit 5 stores the discrimination data and sends a sorting signal when the buckets 3, 3,. Output to change the bucket 3 to the cucumber discharging posture.

At each sorting position, the cucumbers fall onto the upper surface of the draw-out conveyor 7 in a horizontal position. First down the first
It reaches the surface of the conveyor 7a, and is gradually shifted by about 10 degrees from the transfer direction of the sorting conveyor 1. And relay conveyor 8
Then, it is further shifted by 10 degrees and taken over by the second conveyor 7b and transferred. The cucumbers are transported side by side in a horizontal position, and when they reach the vicinity of the elevating and lowering table 9 serving as a vegetable unloading position, workers on standby wait for manual packing in cardboard boxes. At this time, since they are transferred side by side as described above, even if the transfer speed of the draw-out conveyor 7 is reduced, it is possible to secure a sufficient number of transferred items, and the manual packing operation is easy.

It is to be noted that an operator is required at each position of the elevating table, but depending on the number of items to be sorted and drawn out, assistance may be required, or a plurality of positions may be assigned by holding. By the way, in the above embodiment, the draw-out conveyors 7, 7,... Are provided substantially along the sorting conveyor 1, that is, the lifting / lowering type filling tables 9, 9,. When going back and forth between different drawer conveyors 7, it can be moved in the shortest distance without bypassing the end of the drawer conveyor 7, and the efficiency at the time of cheering and holding is not reduced.

When the cucumbers are packed in the cardboard box, they are transferred to the product carrying conveyor 10 by the operator. The product unloading conveyor 10 is transported to a predetermined unloading position. In the case of a plurality of conveyors shown in FIGS. 1 and 2, the cucumber on the surface of the first conveyor 7a, 7c of the draw-out conveyor 7 is 10 degrees or 2 degrees with respect to the transfer direction of the conveyors 7a, 7c.
It is lined up at an angle of 0 degrees, and the relay conveyor 8 and the second
It is taken over by conveyors 7b and 7d. At the transfer portion, the longitudinal direction of the cucumber is shifted by the angle of 10 degrees or 20 degrees with respect to the axis of the pulleys 11 and 12 for tightening the conveyor belt. The transfer of the cucumber causes a time lag in the longitudinal direction of the cucumber, and as a result, compared with the conventional technology (FIG. 5) in which the cucumber stays between the front and rear conveyor belts, the work efficiency is reduced while the cucumber is less damaged. Is being measured.

In the case of FIGS. 1 and 2 described above, the draw-out conveyors 7, 7,... Can be formed substantially along the transfer direction of the sorting conveyor 1, and the interval between each series can be set small in the case of a plurality of series. The area can be reduced. In addition, since the second conveyors 7b and 7d are configured to have an angle, the second conveyors 7b and 7d can be appropriately extended, and the installation length of the draw-out conveyor 7 is not limited.

In FIGS. 6 and 7, since the draw-out conveyor 7 is configured in parallel with the sorting conveyor 1, there is an advantage that the interval between streams can be reduced in the same manner as described above.
