する。Description: (a) Field of Industrial Application The present invention relates to a rocking prevention mechanism of a fruit and vegetable packing device that adsorbs and packs large fruit and vegetables such as watermelon and pumpkin.

下して各西瓜を箱詰する箱詰装置がある。(B) Conventional technology Conventionally, as a packaging device for automatically packaging watermelons and the like as described above, for example, a suction unit is lowered, and each suction unit vertically arranged on the suction unit is aligned at an alignment position. After adsorbing a predetermined number of watermelons packed in a box, each adsorber is moved horizontally to focus each watermelon at a boxing interval corresponding to the box,
There is a packaging device that moves the suction unit to the boxing position in this focused state and lowers the suction unit inside the box body supplied to the boxing position to box each watermelon.

題点があった。(C) Problems to be solved by the invention However, since the large fruit vegetables such as watermelon as described above are much heavier than persimmons, each watermelon adsorbed by each adsorbent is focused and moved to the packing interval. , Or when the suction unit is horizontally moved from the aligned position to the boxing position, the inertia of the movement causes the watermelons to oscillate significantly in the front, rear, left, and right directions, and the suction unit is lowered in this swingable state. Then, the picked watermelon abuts the outer circumference of the box and interferes with the boxing operation, and sometimes the watermelon may fall off due to the impact of the contact, and the boxing work is performed with the swinging of the adsorbent suppressed. However, there is a problem in that the moving speed of the adsorption unit is naturally limited and the work efficiency is deteriorated.

する。On the other hand, as described in Japanese Utility Model Laid-Open No. 61-119903, the present applicant, in an adsorption unit provided with a plurality of adsorbents, has a rectangular frame-shaped regulation frame on the outside of the adsorbents of the constant invariant type. I have already invented an adsorption unit that was constructed to prevent elastic displacement of the fruit that was adsorbed by the adsorbents located on the outer periphery of the array of adsorbents. After adsorbing a small weight of fruit aligned in the adsorbent with the adsorbent, the adsorbent and the fruit in the aligned position are packed in the box without changing the mutual interval of the plurality of adsorbents. And the distance between the adsorbent and the fruit when packed in a box are constant, and since the above-mentioned regulation frame has a non-expandable structure, the same problem as described above occurs even if such means is used.

する。An object of the present invention is to allow a predetermined number of adsorbed fruits and vegetables to be boxed smoothly without abutting the outer peripheral portion of the box body, and to prevent rocking of the adsorbed fruits and vegetables due to inertia, An object of the present invention is to provide a rocking prevention mechanism for a fruit and vegetable boxing device that can speed up packing work and improve efficiency.

を特徴とする。(D) Means for Solving the Problems The present invention is directed to lowering the adsorption unit in which a plurality of adsorbents are vertically installed, and adsorbing each of the fruits and vegetables aligned in the alignment position by each adsorbent that has moved to the adsorption interval. After adsorbing the substance, the adsorption unit is moved to the packaging position, each adsorbent is moved to a packaging interval different from the adsorption interval, and each of the focused fruit and vegetables is put into the box body supplied to the packaging position. In a box-packing apparatus for fruit and vegetables, the outer circumference of each of the adsorbents expands and contracts the distance between them according to the movement of the adsorbents when the interval is changed, and the fruit and vegetables are focused at the boxing interval. Is a rocking preventive mechanism of a fruit and vegetable packing device, in which each restricting body for restricting a position inside the outer peripheral portion of the box is suspended.

Change the spacing of each adsorber to the packing interval that corresponds to the body, and at the same time, narrow the spacing of each regulation body to follow the movement when changing the spacing of each adsorbent, and combine each fruit and vegetable that is focused on the packing interval. The respective regulation bodies are made to follow and contact the outer peripheral surface of the object. Next, move the suction unit to the boxing position, and lower the suction unit inside the box supplied to the boxing position while keeping the vertical position of each fruit inside the outer periphery of the box. Then package each fruit and vegetables.

きる。(F) Effect of the Invention As described above, according to the present invention, each regulating body is brought into contact with the outer peripheral surface of each fruit and vegetable adsorbed by each adsorbent, and each regulating unit is moved by the inertia during movement of the adsorbing unit and each adsorbent. Since the fruit and vegetables are prevented from oscillating and displacing outward, in the boxing operation, the position of each fruit and vegetable focused on the packing interval is positively regulated to the inside of the outer periphery of the box, and the boxing is performed. It is possible to smoothly pack a predetermined number of fruits and vegetables, which are packed at intervals, into the inside of the box.

との両立とを図ることができる効果がある。Moreover, each of the above-mentioned regulation bodies follows the interval movement when changing the interval from the adsorption interval of each adsorbent to the packing interval,
Since the regulation bodies always move so as to maintain contact with the outer peripheral surface of each fruit and vegetable, the outward swing generated during the movement is absorbed by each regulation body, and the fall of the fruit and vegetables due to the swinging action is prevented. As a result, there is an effect that the movement and lowering speed of the adsorption unit can be made faster, and both high-speed packaging work and increased efficiency can be achieved.

きる効果がある。Moreover, the above-mentioned regulation bodies 27 ... Follow the gap movement when changing the gap from the suction gap of each adsorber 8 ... to the packing gap, and each regulation body is always provided on the upper outer peripheral surface of each watermelon S. Since 27 ... move so as to maintain contact with each other, the outward swinging that occurs during movement is absorbed by each regulating body 27 ..., and it is possible to prevent each watermelon S ... from falling off due to the swinging action. As a result, there is an effect that the movement and lowering speed of the suction unit 7 can be made faster to achieve both the speeding up of the boxing work and the improvement of efficiency.

る。In this mechanism, each U-shaped restricting body 27 is vertically installed at an outer peripheral position of each adsorber 8 that is vertically installed on the suction unit 7, and is installed between each end of each restricting body 27. By driving each of the small air cylinders 29 ... In synchronization with the packing operation, and following the pair of left and right restrictors 27, 27 in contact with the semi-peripheral surface of each watermelon S. Similarly to the above-described embodiment, the positions of the watermelons S adsorbed by the respective adsorbents 8 ... Are vertically regulated, and the watermelons S ... Adsorbed are swingingly displaced outward from the outer peripheral portion of the box 24. The effect of preventing is obtained.

箱詰装置の揺動防止機構。1. Fruits aligned in an alignment position by the adsorbents (8) moved down the adsorbing unit (7) in which a plurality of adsorbents (8) are vertically installed and moved to the adsorption interval. After adsorbing the object (S), the adsorbing unit (7) is moved to the boxing position, and the adsorbents (8) are moved to a boxing interval different from the adsorbing interval to focus each fruit (S). In a fruit and vegetable box packing device for packing boxes into a box body (24) supplied to a boxing position, the adsorbents (8) are moved to the outer periphery of each of the adsorbents (8) when the interval is changed. Following the above, the distance between the fruits and vegetables is expanded and contracted, and the fruits and vegetables with the regulators (27) installed to regulate the position of the fruits and vegetables (S) focused on the packing interval inside the outer periphery of the box (24). Swing prevention mechanism for the object packing device.
