Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a fruit packaging device, which can be used in fruit sorting and packaging plants.

Conventional technology includes items that are packed in boxes by arranging the items in advance in the manner in which the items would be arranged when packed in a box to accommodate them, and then suctioning and transporting them integrally with a carrier equipped with suction cups that match the arrangement of the items; There was one in which the objects were picked up and transported one by one, and each object was arranged and packed in a box one by one.

Problems that the invention aims to solve In a sorting plant that sorts fruits by size, the number of classifications by size is at most four.

The most items are in the 12Wf class, and they must be lined up in boxes of the same size and have a certain weight (for example, 5 kg), so the more classification classes there are, the lower the number of items to be packed in each class. On the other hand, since there are many types of standard packing patterns and they are complicated, it is difficult to arrange them in advance in a standard form using automated equipment, and arranging them manually requires a lot of labor. Also,
If the process of picking up, transporting, stuffing, and returning each fruit is repeated, it takes time to move the fruit back to green, so if you shorten the time of the - process, the transfer and packing speed will be faster and the fruit will be placed adjacent to each other in the box. Damage occurs when the fruit collides with the fruit to be packed, and when packing in a complicated arrangement, it is difficult to control the packing position of the suction cup of the device.

Means for Solving the Problems The present invention provides a multi-strip adsorption unit in which a plurality of adsorption bodies (1) capable of adsorbing and holding individual fruits (44) are arranged in tandem and the vertical spacing thereof can be changed freely. (2), the lateral spacing between the adsorption units (2) can be changed freely, and
The structure of the fruit packaging device is characterized in that the relative phase in the vertical direction between the suction units (2) can be freely changed, and the fruits (44) are arranged in a staggered manner and packed in boxes.

Functions and Effects of the Invention The suction bodies (1) of the packaging device are arranged vertically in a suction unit (2) so that the spacing can be changed freely, and the suction units (2) are arranged in plurality so that the spacing can be changed in the horizontal direction. Therefore, the adsorbent (1) attached to the packing device changes the vertical and horizontal spacing to match the orientation of the fruit (44) at the position where it is placed to adsorb the fruit (44). Each adsorbent (
1) are arranged and held together by suction, and while being transferred to a box at a predetermined position, the adsorbents (1) are moved in a staggered manner by changing the relative phase in the vertical direction between each suction unit (2). The fruit (4) is adsorbed and held with the adsorbent (1) arranged in a different manner.
4) can be packed closely together or in a staggered manner with a predetermined spacing between the fruits.

Therefore, the fruits (44) can be packed in staggered boxes easily and quickly without colliding with each other and causing damage.

When the air cylinder (27) is linearly moved, the adsorbed fruits (44) change the relative phase in the vertical direction between the adsorption units (2) and become staggered. At the same time or subsequently, the air cylinder (

As shown in the figure, it is possible to perform staggered packing with a fixed packing pattern, so it is possible to pack fruits that have been sorted by a fruit sorting machine into, for example, 4 to 12 classes, into empty boxes (17) of the same size and pack them by the same weight. When a staggered arrangement is required depending on the number of boxes loaded,
The packaging device with this configuration can be conveniently used.

The air cylinder (27) of the suction unit (2) and the air cylinder (35) for changing the spacing between these multiple strips may be of a stroke adjustable type, and Each mounting leg (31) is attached to the case (

Furthermore, the air cylinder may be a hydraulic cylinder to which pressure oil from a hydraulic pump is piped and moved.

What is shown in FIG. 10 to FIG. 12 is another embodiment diagram.
As shown in Fig. 0 (a), the air cylinder is equipped with four suction units (2), and as shown in Fig. 0 (b), a pair of air cylinders (40) (40) are placed back to back and extend and contract in both directions in the front and rear directions. The rods (41) (41) are provided in the longitudinal center of the adsorption unit (2) in a protruding state, and air pressure is applied to either one of the air cylinders (40) (40) only in the case of fibrillation. In addition, the air cylinder (40) (
A three-boat electromagnetic switching valve (42) is provided in piping to expand the gap between the adsorbents (1) by the elastic force of the spring (25) in a free state in which no pressure is applied to any of the four. The air cylinder (35) for changing the mutual spacing between the two adsorption units (2) is provided with a two-boat switching valve (43) in the same form as the example in Fig. 1, and when installed in this form, By alternately changing the linear movement direction (d) of the adsorbing body spacing of the four suction units (2) to opposite directions, aligning them in the same direction, or switching, as shown in Fig. 11, (a) and ( C) Staggered packing posture with different phases as shown in the figure,
(b) It is convenient to be able to obtain a cramming posture in which the items are aligned vertically and horizontally as shown in the figure. In addition, when packing boxes continuously, if you control the packing so that they are sequentially and alternately packed in the packing positions shown in Fig. 11 (a) and (C), they can be stacked in multiple tiers and placed in separate boxes. When packing, the fruits (40) in each of the plurality of tiers do not overlap in the same position, but the fruits (44) in the upper or lower tier are positioned between the fruit (44) and the fruit (44) to ensure stability. This is good because the fruits (44) can be stacked in the same state, and the height of the stack is low, making it difficult for the fruits (44) to be damaged.

Incidentally, when the number of fruits (44) to be packed is different, a standard packing pattern as shown in FIG. 12 can be made.
