Moreover, since the suction surface of each suction pad elastically deforms in accordance with the peripheral surface shape of each cucumber, even if there is a slight deviation in the suction position between each cucumber and each suction pad, no suction failure will occur, The cucumber with a unique shape can be reliably boxed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a long object adsorber used for mechanically packing long fruits and vegetables such as cucumber, carrot, potato, and eggplant.

[0002]

[Prior art]

 Conventionally, as a method of packing cucumbers like the above-mentioned example, as shown in FIGS. 13 and 14, for example, a soft member such as synthetic rubber is formed on the upper peripheral surface of each cucumber K ... Each suction surface 64a of each suction pad 64 is pressed, and each cucumber K is suction-held by the negative pressure of the suction blower (not shown) connected to each suction pad 64. Next, when the cucumbers K, which are suction-held by the suction pads 64, are stored in the corrugated cardboard box B, the negative pressure of the suction blower (not shown) is shut off or stopped, and the suction pads 64 are suction-held. There is a way to pack all the cucumber K ...

[0003]

[Problems to be solved by the device]

 However, as described above, the suction surface 64a of the suction pad 64 is pressed flat against the upper peripheral surface of the cucumber K, so that the suction surface 64a of the suction pad 64 corresponds to the peripheral shape of the cucumber K without any gap. Since it is difficult to bring them into close contact with each other and the air is sucked through the gap formed on the suction surface 64a side of the suction pad 64, the airtightness cannot be secured during the suction. Moreover, even if the suction position between the cucumber K and the suction pad 64 is slightly displaced, the suction surface 64a of the suction pad 64 does not follow the shape of the peripheral surface of the cucumber K and the suction blower (not shown). Since the negative pressure due to fluctuates, the negative pressure when adsorbing and holding cucumber K becomes unstable, and there is a problem that the cucumber K having a peculiar shape cannot be reliably boxed.

In view of the above problems, the present invention secures airtightness during adsorption by closely adhering the adsorption surface of the long object adsorbent to the upper peripheral surface of the long fruit having a peculiar shape without any gap. It is an object of the present invention to provide a long object adsorber capable of reliably boxing long vegetables and fruits having a unique shape.

[0005]

[Means for Solving the Problems]

[Action]

 In the long object adsorbent according to claim 1, when the adsorption surface of the adsorbent is pressed against the upper peripheral surface of the long fruits and vegetables, the adsorption surface of the adsorbent has gaps corresponding to the upper peripheral surface of the same long fruits and vegetables. Since there is no adhesion, airtightness can be secured during adsorption.

In the long object adsorbent according to claim 2, in addition to the operation according to claim 1, an elliptical annular member formed of a hard member is press-fitted on the adsorbing side inner peripheral surface of the adsorber. By doing so, the adsorption surface of the adsorbent is elastically deformed in the X and Y directions by the long diameter portion and the small diameter portion of the elliptical annular member, and the adsorption surface of the adsorbent is the upper peripheral surface of the long fruits and vegetables. It is transformed into a concave shape corresponding to.

In the long object adsorbent according to claim 3, in addition to the operation according to claim 1 or claim 2, an elastic body is attached to the back surface side of the adsorbing surface constituting the adsorbent. Then, the adsorption surface of the adsorbent is pressed against the upper peripheral surface of the long fruits and vegetables by the elastic body, and the adsorption surface of the adsorbent is forcibly adhered to the upper peripheral surface of the long fruits and vegetables without a gap.

[0011]

[Effect of device]

 According to this invention, since the adsorption surface of the adsorbent is closely attached to the upper peripheral surface of the long fruits and vegetables without any gap, no gap is formed between the long fruits and vegetables and the adsorbent is airtight during adsorption. It is possible to secure the property, and the negative pressure necessary for adsorbing and holding long fruits and vegetables can be stably obtained. Moreover, since the adsorption surface of the adsorbent is elastically deformed according to the peripheral surface shape of the long fruits and vegetables, even if there is a slight deviation in the adsorption position between the long fruits and vegetables, no adsorption failure will occur. The boxing work of long fruits and vegetables having a unique shape can be surely performed.

[0012] Moreover, since a large number of long fruits and vegetables are adsorbed and held and packed in a box, the labor and work of packing one by one by hand can be saved, and an appropriate number of long fruits and vegetables can be collectively packed in a packaging container or the like. The packaging unit price is lower than that of the packaging method, and the time and packaging cost required for the packaging work can be reduced, and the labor and efficiency of the packaging work can be improved.

In addition, by simply press-fitting the elliptical annular member on the suction-side inner peripheral surface of the flexible adsorbent, the adsorbent can be easily formed into a concave shape corresponding to the upper peripheral surface of the long fruits and vegetables. be able to.

Further, when the adsorption surface of the adsorbent is pressed against the upper peripheral surface of the long fruits and vegetables, the adsorption surface of the same adsorbent is deformed by the elastic body so as to conform to the upper peripheral surface of the long fruits and vegetables. Thus, for example, even long fruits and vegetables such as cucumbers having different irregularities and outer diameters can be closely adhered to each other without a gap, and a predetermined negative pressure is applied to the adsorption portion of the long fruits and vegetables. Since, the long fruits and vegetables can be more surely adsorbed and held.

Assuming that the illustrated embodiment is configured as described above, the operation when the cucumber boxing apparatus 1 adsorbs and holds the two groups of cucumber K ... First, as shown in FIG. 1, a large number of cucumbers K ... brought in from the producer side are sequentially transferred to the loading conveyor 3, and each cucumber K ... supplied from the loading conveyor 3 is loaded into each. The cucumbers K are sequentially loaded into the concave mounting portions Tb of the alignment tray T which are transported to the loading position on the orbiting conveyor 2 by being accelerated and transported by the rollers 30 and 31. At the same time, the front end of each cucumber K ... is brought into contact with the aligning plate Tc formed at the front end of the aligning tray T on the longitudinal side and aligned in a horizontal line. When the cucumbers K transferred on the alignment tray T are misaligned or insufficient, the mounting posture and number of the cucumbers K are manually corrected by the operator.

Next, as shown in FIG. 2, the retracting cylinder 22 is caused to project, and the two aligning trays T, T are temporarily stopped by the stopper 21 at the aligning position on the orbiting conveyor 2. At the same time, the retreating cylinder 25 and the pressing cylinder 27 of the aligning machine 23 are operated, and the cucumbers K ... Mounted on the rear row side aligning tray T are collectively retracted by the pressing pad 29. The rear end of each cucumber K ... is brought into contact with the alignment plate Tc formed at the rear end and aligned in a horizontal line. After that, the retracting cylinder 25 and the pressing cylinder 27 are operated to return, and the pressing pad 29 is returned to the initial position. At the same time, the retracting cylinder 22 is retracted and the two aligning trays T 1, T 2 are conveyed in parallel to the aligning position on the circulating conveyor 2.

Next, as shown in FIGS. 7 and 8, the elevating cylinder 35 of the boxing machine 4 is lowered to move the front and rear rows of the two aligning trays T, T. Each cucumber K ... is pressed against each suction pad 42, and at the same time, each suction surface 42a of each suction pad 42 is closely adhered to the upper peripheral surface of each cucumber K. At the same time, the support pads 50 and 51 are brought into contact with the upper peripheral surfaces of the cucumbers K adsorbed and held by the adsorption pads 42, respectively, and the rear end portions of the cucumbers K ... are supported in a posture inclining slightly downward. To do. Since the suction surface 42a of the suction pad 42 is elastically deformed in accordance with the peripheral shape of the cucumber K, even if the suction position between the cucumber K and the suction pad 42 is slightly deviated, a suction failure may occur. The cucumber K having a unique shape is surely adsorbed and held.

After that, the moving cylinder 34 and the lifting cylinder 35 are operated so that the suction pads 42 hung vertically on the lifting frame 36 suck and hold the respective cucumbers K in the front and rear rows from the aligned position. Move to the packing position. As shown in FIG. 3, FIG. 4, and FIG. 5, the forward / backward movement cylinders 43, 43 and the expansion / contraction cylinders 48, 48 are actuated to move the front and rear rows of the cucumbers K adsorbed and held by the adsorption pads 42. While converging at the boxing interval, the opposite end portions of the front row side cucumber K ... and the rear row side cucumber K ... adsorbed and held by the respective suction pads 42 ...

On the other hand, as shown in FIG. 9, the box-carrying conveyor 55 is driven to convey the box-formed corrugated box B to the lower part of the box packing position, and the lifting motor 60 is driven to drive the same. The cardboard box B conveyed to the lower part of the position is vertically raised to a suitable height by the box lift 57. At the same time, the opening cylinder 54 is actuated to slightly open the flaps Ba ... of the corrugated cardboard box B placed on the box lift 57 in four directions by the four open plates 52 ... 10 is performed by lowering the lifting cylinder 35 to collectively store the front and rear rows of the cucumbers K, which are suction-held by the suction pads 42, in the packaging bag P in the cardboard box B and release the suction. As described above, the boxing work for each cucumber K for one step is completed.

In the same manner as described above, the moving cylinder 34 and the lifting cylinder 35 are restored to return the suction pads 42 to their initial positions, and the advancing / retreating cylinders 43, 43 and the expanding / contracting cylinder 48 are returned. , 48 are returned to separate each suction pad 42 at an initial interval, and then each cucumber K placed on each of the next alignment trays T, T is sucked by each suction pad 42. The cucumbers K ... of the two groups that are held and sucked and held by the same suction pads 42 ... Are superposed on top of each other and packed in a corrugated cardboard box B.

After packing a predetermined number of each cucumber K ... in a corrugated cardboard box B, the lifting motor 60 is reversely driven to drive the corrugated cardboard box B mounted on the box lifting platform 57 to the box unloading conveyor 5 6. Then, the box unloading conveyor 56 is driven to transport the boxed corrugated cardboard box B to the next step (for example, bag packaging step, box packaging step).

When the cucumbers K for one stage are packed in a box, the two alignment trays T, T conveyed to the alignment position on the orbiting conveyor 2 are transferred to the next conveyor 2c, A box packing operation of each cucumber K ... brought in from the producer side by sequentially transporting a large number of each of the array trays T ... Mounted on the conveyors 2a, 2b, 2c, 2d from the loading position to the alignment position. To continue.

As described above, when the two groups of cucumbers K placed on the two respective alignment trays T and T are sucked and held by the suction pads 42, the upper peripheral surface of the cucumber K having a peculiar shape. In contrast, since the suction surface 42a of the suction pad 42 is closely attached without any gap, airtightness can be ensured during suction, and the negative pressure necessary for suction holding the cucumber K can be stably obtained. . Moreover, since the suction surface 42a of the suction pad 42 is elastically deformed in accordance with the peripheral shape of the cucumber K, even if there is a slight deviation in the suction position between the cucumber K and the suction pad 42, no suction failure will occur. The boxing work of cucumber K, which has a unique shape, can be performed reliably.

Moreover, since the two groups of cucumbers K ... arranged in parallel are adsorbed and held and packed in a batch, it is possible to save the labor and work of packing a large number of each cucumber K ... one by one by hand. Moreover, the packing unit price is lower than the box packing method in which the two groups of cucumbers K ... are packed in a packing container at the same time, which reduces the time and the packaging cost required for the box packing work, and saves the packing work efficiency and efficiency. Can be planned.

In addition, by simply press-fitting the elliptical deforming ring 42c into the annular portion 42b of the suction pad 42 formed in a bellows shape, the suction surface of the suction pad 42 has a concave shape corresponding to the upper peripheral surface of the cucumber K. 42a can be easily formed.

FIG. 11 shows a suction pad 71 according to another embodiment. This suction pad 71 has a pad main body 72 formed in the same structure as the suction pad 42 described above, and the pad main body 72. The elastic body 73 is attached to the back side of the suction surface 72a. The above-mentioned elastic body 73 is a normal body and maintains a constant shape without a high internal pressure, but when an external pressure is applied, the elastic body 73 is appropriately elastically deformed and dented in accordance with the pressure, for example, urethane rubber or a soft material. It is made of synthetic rubber.

When the cucumber K is adsorbed by the adsorption pad 71 configured as described above, when the adsorption surface 72 a of the adsorption pad 71 is pressed against the upper peripheral surface of the cucumber K, as shown in FIG. Since the suction surface 72a of the cucumber is elastically deformed by the elastic body 73 so as to fit to the upper peripheral surface of the cucumber K, for example, the cucumber K suction part has protrusions or striped irregularities, or the cucumber K suction part is Even with a slightly smaller diameter, the suction pad 71 can be closely attached to the peripheral surface of the cucumber K without any gap.

Therefore, when the air inside the suction pad 71 is sucked, a predetermined negative pressure acts on the suction portion of the cucumber K, and the cucumber K can be more surely sucked and held.

In the correspondence between the configuration of the present invention and the above-described embodiment, the long fruits and vegetables of the present invention correspond to the cucumber K of the embodiment, and the long object adsorbent is the suction pad 42, The annular member corresponds to the deformable ring 42c, but the invention is not limited to the configuration of the above-described embodiment.
