Abstract

PURPOSE:To automatically pack fruits in cases, improve the efficiency and save man-hour for case-packing work by a method wherein fruits are placed on a partition material to be conveyed by a partition material conveyer, and the partition material is moved up and down at the terminal of the conveyer to put the fruits into a corrugated board case in two or more layers. CONSTITUTION:Fruits F sorted out by a sorter 8 are supplied to a drawing-out conveyer 7. The fruits F after passing through a vibration conveyer 15 and a line-up conveyer 12 are taken out one by one by a take-out conveyer 10 and lined up on a partition material 2 to be conveyed by a partition material conveyer 12. Then, the partition material 2 is transferred to the specified position (a) at the terminal of the partition material conveyer 12. On the other hand, the first one of corrugated board cases 5 on a case supply conveyer 14 is supplied to the specified position (b). A sucking box 44 of a carrier 1 is lowered to suck the fruits F by a fruit sucker 3 and the partition material 2 by a partition material sucker 4. After that, the sucking box 44 is lifted above the corrugated board case 5 and then lowered to put the partition material 2 into the corrugated board case 5.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned drawbacks, and the partition members 2 and 2 at the transfer start end portion.
Partitioning material conveyor 12 that receives ...
In the middle part of the transfer, the end side of the pull-out conveyor 7 to be transferred to the partition material 2 on standby on the partition material conveyor 12 is looked into, and the partition material conveyor 12 concerned.
The fruit F on the partition 2 and the partition 2
And a carrier 1 for packing in a corrugated cardboard case 5 which is integrally lifted and stands by in the vicinity thereof.

[0004]

Effect of the Invention In the transfer intermediate portion of the partition material conveyor 12 which receives and transfers the partition materials 2, 2, the selected fruits F should be transferred onto the partition material 2 waiting on the partition material conveyor 12. The end side of the pull-out conveyor 7 is looked into, and at the transfer end portion of this partition material conveyor 12, each fruit F on the partition material 2 is shown.
Since the carrier 1 for packaging the cardboard case 5 that integrally lifts and the partition material 2 and stands by in the vicinity is provided, the fruit F is placed on the partition material 2 that is transferred by the partition material conveyor, and is kept as it is. It is transferred, and at the terminal end thereof, it is lifted up in the state where the partitioning material is placed and housed in the corrugated cardboard case 5 in the vicinity thereof, and is housed in a plurality of stages in this corrugated cardboard case, which is advantageous in terms of labor saving Is.

Further, since the partition material conveyor 2 can be constructed along the drawing conveyor 7 and can be arranged below it,
In a sorting device that requires a plurality of drawer conveyors to be provided in parallel, the space for the partitioning material conveyor 2 is not increased.

It is configured to move between a or b.

The partition member 2 is made of corrugated cardboard and is provided in conformity with the shape of the bottom surface of the corrugated cardboard case 5. The fruit F is arranged on the upper side of the partition member 2 so that the partition member adsorbing member 4 alone does not bend and hold it. Is molded into. The fruit adsorbent 3 has an adsorption port 49 to be adsorbed by bringing the lower opening into contact with the surface of the fruit F. An attachment portion 50 having a hole to be fitted to the air pipe 43 protruding downward from the lower surface of the suction box body 44 in a continuous manner with the upper small diameter portion is formed, and is attached to the air pipe 43.

Similar to the fruit adsorbent 3, the partition adsorbent 4 has a size smaller than that of the fruit adsorbent 3, and two partition adsorbents are provided in the left and right spaces of the fruit adsorbent 3 arranged in a staggered manner. Set up. The corrugated cardboard case 5 has a flap portion 51 that serves as a lid on the upper side of the cube. Fruit etc. on the outer surface
The class is printed.

The case conveyor 14 is a chain conveyor stretched between a pair of left and right chains 52 along the transfer direction C, and the chains 52 are provided with receiving portions 53 for receiving the corrugated cardboard cases 5 at their respective links. Further, at the position B of the case 5, the vertical air cylinder mechanism 54 and the upper and lower guide rods 5 are provided in the space between the chains 52 on the left and right sides.
5, a lift device 57 including a receiving member 56 and the like located above these and receiving the bottom of the case 5 is provided.

Reference numeral 25 is a color sensor on the transfer side of the fruit reversing device 24 for recognizing the loose portion. The edge detection information is used as a drive system signal for the air cylinder mechanism 22.

The operation of the above example will be described. Sorting device 8
The fruits F sorted according to size are dropped on the pulling conveyor 7 of the size class due to the fall of the receiver 6. The fruits F aligned through the vibrating conveyor 15 and the aligning device 9 are adsorbed by the three adsorbing devices 32 of the extracting device 10 one by one, and are arranged in a zigzag manner on the partition material 2 transferred by the partition material conveyor 12. ..

The partition material 2 on which the fruits F are arranged is transferred to the end portion of the partition material conveyor 12, that is, a predetermined position a.
On the other hand, of the cardboard case 5 on the distribution conveyor 14,
When the leading corrugated cardboard case 5 reaches the predetermined position (b), the controlled lift device 57 raises the corrugated cardboard case 5, and at the same time, the stopper device 58 operates to stop the transfer of the subsequent cardboard case 5.

When the fruit F is placed at the position a and the cardboard case 5 is placed at the position b, the suction box body 44 of the carrier 1 is lowered so that each fruit suction body 3 presses the fruit F from above and sucks the partition material. The body 4 presses the partition member 2 and applies suction negative pressure to adsorb it. Next, the air cylinder mechanism 40 is contracted and floated to a predetermined height. Further, the air cylinder mechanism 48 is extended and moved, and when it reaches the position b, it stops. The lift device 57 holding the corrugated board case 5 on the receiving body 56 rises to the highest position and stops by the extension of the air cylinder mechanism 54, and the air cylinder mechanism 40 of the carrier 1 extends to move to the suction box body 44. When the sheet is lowered, the partition material 2 that has been adsorbed and transferred reaches the inner bottom surface of the cardboard case 5.

The suction of the adsorbents 3 and 4 is released, and the air cylinder mechanism 40 is contracted and raised, and at the same time, the corrugated cardboard case 5 is contracted and lowered by the air cylinder mechanism 54. Carrier 1 returns to position a and the next partition 2 and fruit F
When and are sucked, floated, moved laterally and stopped at the position B, the lift device 57 moves up to a position where the second stage in the case 5 should be packed and the carrier 1 is packed with the partition material 2 and the fruit F. Similarly, at the third time, when the lifting device 57 rises to the height at which it can be packed in the uppermost stage of the three-stage stack in the case 5 and finishes the packing, the next descending descends to the bottom of the five stages, so packing in the box. The bottom surface of the corrugated cardboard case 5 is received by the receiving portion 53 of the chain 52 of the box conveyor 14 and the transfer is started in the transfer direction C, and at the same time, the stop plate 60 of the stopper device is started.
Moves down to feed the next corrugated board case 5 onto the lift device 57, and the stopper device 58 completes the feeding of each case.
