Detailed Description of the Invention

[0001]

The present invention relates to long vegetables such as cucumber (cucumber), loofah (melon), carrot or radish.
The present invention relates to a sorting machine that sorts and sorts by shape and size, and more particularly, to a structure of a supply unit that conveys long vegetables from a vegetable storage unit such as a container to the starting end of a conveyor.

[0002]

2. Description of the Related Art As a sorter for sorting long harvested vegetables into shapes and sizes, there is, for example, a cucumber sorter, in which one cucumber stored in a container is placed at the start end of a conveyor. It depended on human power to supply each by hand.

[0003]

In the above-mentioned prior art, the cucumber is supplied manually, which is labor-intensive, and the manual supply operation must be performed in accordance with the transfer behavior of the transfer conveyor. There is also a face,
There was room for improvement. An object of the present invention is to provide a sorting machine that saves labor by automating the supply means.

[0004]

To achieve the above object, the present invention provides a conveyor for conveying long vegetables, a supply means for supplying long vegetables to the conveyor, and a long conveyor conveyed by the conveyor. Equipped with a selection means for selecting and sorting the vegetables, the supply means is a suction pad capable of adsorbing to the surface of the long vegetables, a suction pump for expressing the suction action of this suction pad, and the suction pad can be driven up and down. A suction device composed of a moving mechanism and a relay body on which long vegetables are placed, a receiving position for receiving and placing the long vegetables adsorbed on the suction pad, and a long vegetable placed on the relay body. Is composed of a supply moving device capable of driving and moving to a supply position capable of supplying to the starting end portion of the conveyor.

In the configuration described above, a plurality of suction pads are arranged side by side in the transport direction of the transport conveyor, and the plurality of suction pads can be moved so that the interval between adjacent suction pads is increased in the transport direction. The mechanism may be provided in the suction device, and a plurality of relay bodies may be arranged at intervals corresponding to the suction pads in the state where the expansion mechanism is moved.

In the above configuration, a plurality of suction pads are arranged side by side in the transport direction of the transport conveyor, and the space between the plurality of suction pads adjacent to each other in the transport direction is set to be suitable for suction of long vegetables. In addition to setting the spacing, the spacing between adjacent ones of the plurality of relays in the transport direction is set to the close spacing corresponding to the suction pads at the suction-adapted spacing at the receiving position and the transport direction from the close spacing at the supply position. The interval changing mechanism that can be changed to a suitable supply interval suitable for supplying to the conveyor
Conveniently, it is equipped with a supply transfer device.

In the above configuration, a boss member is provided that supports the relay body in a reversible manner in a mounting posture in which long vegetables are placed and a releasing posture in which the long vegetables placed are discharged and dropped. A plurality of members are slidably supported on a support shaft along the transport direction, and a driving means for moving the plurality of boss members in the axial direction of the support shaft is provided, and a rotation mechanism for reversing the boss members is provided for supply. It is further advantageous if the mobile device is constructed. In the configuration, multiple suction pads are arranged side by side in the transport direction of the transport conveyor, and the spacing between adjacent suction pads in the transport direction is set to a suction compatibility interval suitable for suction of long vegetables. In addition, the interval between the adjacent ones of the plurality of relays at the receiving position in the transport direction is set to a close interval corresponding to the suction pads at the suction-adapted distance, and the plurality of relays are moved to the supply position. In this state, it is also convenient to provide a time difference supply means for supplying a plurality of long vegetables placed on the relay body to the conveyor in sequence with a time difference. In the configuration, the relay body is provided with a boss member that supports the relay body so as to be capable of reversing between a mounting posture in which long vegetables are placed and a discharging posture in which the long vegetables placed are discharged, and is driven to move in the transport direction. Plural operations in a state in which a plurality of relays are in the supply position so that the movable arms are provided and the operation arms attached to the plurality of boss members arranged in the transport direction are sequentially rotated by the movement of the movable bodies. It is more convenient if the time difference supply means is configured by arranging the arm and the working body relative to each other.

[0008]

According to the first aspect of the present invention, long vegetables are adsorbed and lifted by the adsorbing action of the adsorbing pad, then the adsorbing action is released and the long vegetables are transferred to the relay body, and then the supply moving device is used fully. As a result, long vegetables placed in a container or the like can be carried to the starting end of the conveyor, and the supply operation can be automated. In order to lift long vegetables by suction and carry them to the conveyor, there are two methods: a means for moving the suction pad itself and a means for moving the long vegetables delivered from the suction pad by a dedicated moving mechanism. Conceivable.

[0009] In the means (1), the suction pad itself is moved and the whole apparatus is relatively easy to be integrated, and even after the suction and lifting, the suction must be continued until the end of the conveyor. Is. However, the adsorptive effect on vegetables having a non-uniform surface shape is disadvantageous, and if the suction pump is made too strong, the vegetable surface may be damaged. Therefore, the actual adsorptive power cannot be so strong. Therefore, if a start shock, a stop shock during movement, or other disturbance (for example, strong wind of a blower in another device acts), it may fall relatively easily, and the transport reliability There is room for improvement in this respect (for example, see Japanese Patent Application No. 6-155604 filed earlier).

The means of (1) requires a separate device for the adsorbing device and the feeding moving device, but since long vegetables can be stably transferred from the receiving position to the starting end of the conveyer conveyor while being placed on the relay body, the feeding movement is possible. It prevents the machine from falling during the transfer due to a start shock, a stop shock, or a disturbance when the apparatus is operated. In other words, the time to maintain the unstable support state due to adsorption is greatly reduced,
It is possible to increase the certainty that the conveyance can be performed without a drop mistake on the way. The present application adopts this means.

Since the lifting by suction and the transfer to the transfer conveyor can be performed in separate steps, these steps can be performed in duplicate, and the operation can be performed more efficiently than the means which cannot be performed in duplicate. Like In addition, even if the posture of long vegetables is slightly disturbed when picked up by suction, they can be aligned by being delivered to the relay body, and a posture correction effect that can be supplied to the transport conveyor in a regular posture can be expected. It also becomes like.

By the way, when long vegetables on the conveyor are conveyed without a gap, it is difficult to judge and sort out each element such as shape and size one by one. It is necessary to keep the vegetables apart.

According to the second aspect of the present invention, long vegetables can be separated in advance in the conveying direction by the expanding mechanism to be in a state suitable for the selecting operation of the selecting means, and then can be supplied to the conveyor, so that the subsequent selecting operation can be performed well. Will be able to.
Since the expansion mechanism is provided in the suction device, in the supply moving device, it is sufficient to simply move the plurality of relays in the transfer direction of the transfer conveyor, and the structure of the supply moving device can be simplified.

According to the third aspect of the present invention, the long-range vegetables can be separated in advance in the conveying direction by the interval changing mechanism so as to be in a state suitable for the selecting operation of the selecting means, and can be supplied to the conveying conveyor, and the subsequent selecting operation can be performed well. To be able to Since the interval changing mechanism is provided in the feeding and moving device, the adsorbing device only needs to use the adsorbing means only for lifting long vegetables, and the maintenance time of the unstable supporting state due to the adsorbing is minimized. Can
It is possible to further increase the certainty that the conveyance can be performed without a drop error on the way.

It is necessary to have means for moving the relay to the starting end of the conveyor and then taking out the vegetables placed on the relay and transferring the vegetables onto the conveyor. According to the structure of claim 4, long vegetables are transferred from the receiving position to the starting end of the conveyer conveyor by slidingly moving the boss member that supports the relays separately. Then, the rotation mechanism is operated on the transport conveyor to change the relay body from the mounting posture to the discharging posture, so that the long vegetables placed on the relay body can be transferred to the transport conveyor. That is, with this means, long vegetables can be continuously placed on the relay body from the receiving position to the supplying position, and, for example, it is possible to reduce transport errors as much as possible as compared with the means of reversing moving while transferring. It will be possible.

According to the structure of claim 5, the means for transferring the vegetables of the relay body to the conveyer conveyor is made to appear by the reversing operation of the relay body. It is a means for expanding the interval between adjacent vegetables in a state in which they are transferred onto the conveyor by expanding the interval of the reversing operation of the relay instead of expanding the interval so that the vegetables are suitable for the selection operation. With this time difference supply means, it is possible to appropriately change and set the interval between long vegetables on the conveyor by adjusting the time difference.

In a sixth aspect of the present invention, a plurality of operating arms are arranged side by side in the moving direction of the working body, and the operating arms are sequentially operated as the working body moves. It is configured. Due to the structure of the time difference supply means that acts on the boss member that is constantly moving, for example, damage to the circuit element due to inertial shock is greater than that of electrical means that makes a difference in the reversing operation timing of the relay body by a timer. There is an advantage in that there is no risk of breakdown such as breakage or disconnection.

[0018]

As a result, in any of the sorting machines described in claims 1 to 6, the pick-up of vegetables by adsorption and the picked-up vegetables being placed and carried by the relay body are long on the carrying conveyor. By devising a way to supply vegetables, the possibility of dropping during transportation is excellent, reliability is high, work efficiency is improved, and the feeding means can be automated in a state in which posture is not disturbed during transportation. In addition to the above effects, the sorting machine according to the second and third aspects has an advantage that long vegetables can be supplied to the conveyer conveyor in a state where the sorting operation in the sorting operation can be easily performed, which contributes to ensuring the sorting operation.

In the sorting machine according to claims 3 to 6, there is an advantage that the transfer rate of long vegetables in the adsorbed state can be minimized to minimize the risk of conveyance error due to the adsorption failure.
Further, in the sorting machine according to the fourth aspect, there is an advantage that the risk of vegetables falling during transportation is further reduced and the reliability of transportation is improved. In the sorting machine according to claims 5 and 6,
There are advantages that the supply moving device can be simplified, and that the vegetable transportation interval on the transportation conveyor can be easily adjusted.
Further, in the sorting machine according to the sixth aspect, there is an advantage that the operation of the time difference supply means can be ensured, and in that respect, the operation reliability as a whole can be improved.

And a suction pump 13. The suction pad 10 is configured by fitting and connecting a bellows tube 14 having a suction surface 14A formed at a lower end thereof to a tube rod 10A.
By the function of 4, the suction surface 14A can be vertically displaced and pivotally displaced with respect to the cylindrical rod 10A. The suction pads 10 are arranged in a zigzag pattern in a plan view, and the distance between the adjoining ones in the transport direction is set to a suction-adapted distance suitable for adsorbing cucumber, and the plurality of suction pads are adsorbed. The pad 10 and the fixedly arranged suction pump 13 are connected and connected by a group of suction hoses 18 which are bendable.

The three-dimensional moving mechanism 12 includes a vertically moving mechanism 12A which can vertically move the working body 11 in a predetermined range and a vertically moving mechanism 12A which can move the vertically moving mechanism 12A in a front-back direction (conveying direction of the belt conveyor B) in a predetermined range. Front and rear moving mechanism 12B,
The front-rear moving mechanism 12B includes a left-right moving mechanism 12C that is movable in a left-right direction (direction orthogonal to the conveyance direction of the belt conveyor B) within a predetermined range.

The up-and-down moving mechanism 12A is composed of an up-and-down cylinder (hydraulic cylinder or electric cylinder).
2B is a base 2 of the vertical movement mechanism 12A that is mounted on the screw shaft 17 and the guide shaft 27 that are laid across the front and rear moving bodies 39 and 37.
The gear motor GM is provided so as to support 8 through and to rotate the screw shaft 17 for rotation. The left and right moving mechanism 12C includes drive units (not shown) provided in the front and rear moving bodies 39 and 37, and is provided with front and rear fixed rails 30 for the wheels 29 driven by these drive units.

The support structure of the suction pad 10 will be described in detail. As shown in FIGS. 3 to 6, the plate body 31 to which the plurality of suction pads 10 are attached is attached to the working body 1 via the descending urging mechanism 32.
It is attached to No. 1 and has a flexibility in the contact area between the suction pad 10 and the cucumber by the downward movement by the elevating cylinder 12A, and the cushion effect at the time of contact is obtained. The descending urging mechanism 32 fits the insertion rod 33 fixed to the plate body 31 into the boss portion 11 a of the working body 11 via the winding spring 34, and the guide rod 35 fixed to the plate body 31 to the working body 11. It is configured to pass through the notch 11b at the end.

A limit switch 42 is attached to the lower end of the boss 11a so that the limit switch 42 operates when the amount of rise of the plate 31 with respect to the working body 11 reaches a predetermined value. When 42 is operated, the lowering movement of the elevating cylinder 12A is stopped. That is, as shown in FIGS. 6A and 6B, an elevating cylinder (in an elevating mechanism) capable of driving and elevating a plate body (corresponding to an adsorption frame) 31 on which the suction pad 10 is vertically movable within a predetermined range. Equivalent) 12A is the moving mechanism 12
And a spring 34 capable of urging the suction pad 10 downwardly with respect to the plate body 31 is provided, and as the amount of upward movement of the suction pad 10 with respect to the plate body 31 increases, the downward urging force becomes stronger. The spring 34 is arranged and set in such a state that the limit switch 42 and the elevating mechanism 12 are linked so that the downward movement of the plate 31 is stopped by the operation of the limit switch 42 that operates when the amount of upward movement reaches a predetermined value. Has been done.

As shown in FIG. 3, the suction pump 13 is constituted by a reciprocating piston pump in which a piston 13p reciprocates, and a total of nine suction pumps are provided for each suction pad 10. A drive bar 36 extending over the nine piston rods 13a is provided, and the drive bar 36 is reciprocally driven and moved by a single drive device 37 having a swing arm 38, whereby the linkage transmission mechanism E is formed. It is configured. Limit switches 40 and 41 for determining the front and rear swing limits of the swing arm 38 are provided. When the switch 37 comes into contact with the front switch 40 of the swing arm 38, the drive device 37 reverses to swing the swing arm 38 rearward. Then, when the rear switch 41 is brought into contact with the rear switch 41, the swing arm 38 is linked to swing forward. Therefore, the moving region of the piston pump 13 can be adjusted and set according to the distance between the storage box 1 and the start end of the belt conveyor B, and there is an advantage that waste of reciprocating more than the actually required amount can be eliminated.

Further, as shown in FIG. 3, the parallel pitch L'of the suction pads 10, 10 which are adjacent to each other in the transport direction is smaller than the parallel pitch L of the cucumbers aligned and stored in the storage box 1. , That is, L '<L, and 9
It is arranged that any one of the suction pads 10 sucks on the cucumber without fail.

As shown in FIGS. 7 to 9, the supply moving device A
b is a drive unit 44 capable of reciprocating all the relay bodies 43 in the transport direction at the same time, an interval changing mechanism 45 for expanding and contracting the space in the transport direction between adjacent relay bodies 43, and the relay body 4.
3 and a rotating mechanism 57 capable of reversing. First, the relay 43 has a gutter-shaped tray 43 at the tip of the rotating shaft 43b.
A boss member 46, which is configured by attaching a and rotatably supports the rotating shaft 43b, is externally fitted to the screw shaft 48, and the end of the rotating shaft 43b is slidable on a support rail 47 oriented in the transport direction. It is fitted. An operation arm 49 is attached to a protruding end of the rotating shaft 43b from the boss member 46 so as not to be relatively rotatable, and a link plate 50 is erected and connected between adjacent operation arms 49, 49.

A torsion spring 51 is mounted on the rotary shaft 43b between the tray 43a and the boss member 46, and the relay 43 is fixed to the arm piece 43c and the stopper 4 of the boss member 46.
The bosses 46 are provided with fulcrums 52 standing upright, and a pantograph mechanism 53 having the fulcrums 52 as the connection center is provided. It is configured. By the way, among the plurality of boss members 46, only the main boss member 46 closest to the storage box 1 is screwed into the screw 48, and the others are slidably fitted to the screw shaft 48, and the main boss member 46 is also included. The stopper member 54 acting only on the operation arm 49 and the electric cylinder 55 for expanding and contracting the pantograph mechanism 53 are provided.

More specifically, the stopper member 54 is fixed to the frame 58 of the supply moving device Ab, and the link conveyor 50 on the side of the conveyor B has a long hole 50a for pinning the adjacent operation arm 49. It is connected. The main body 55 a of the electric cylinder 55 is supported by the main boss member 46, and the piston rod 55
b is pivotally connected to the third fulcrum 52 from the main boss member 46. Further, a motor mechanism 56 is provided which is capable of rotating the screw shaft 48 in the forward and reverse directions. In other words, if the motor mechanism 56 is driven, all the relay bodies 43 can be moved in the transport direction while maintaining their mutual intervals, whereby the drive means 44 is configured, and if the electric cylinder 55 is extendedly driven, the pantograph can be obtained. The mechanism 53 extends to increase the mutual distance between the relay bodies 43, and a distance changing mechanism 45 that can reduce the mutual distance by driving the relay bodies 43 is shortened. Further, the stopper member 54, the operation arms 49, and the links. A rotation mechanism 57 is configured by the plate 50.

The rotating mechanism 57 can be operated only when the cucumber is supplied to the conveyer conveyor B when the interval changing mechanism 45 is expanded to the maximum. That is, as shown in FIG. 9, when the electric cylinder 55 is fully extended and driven, the connecting pin 49a of each operation arm 49 provided other than the main boss member 46 causes the rear end of the elongated hole 50a of the link plate 50 (in the carrying direction). When the motor mechanism 56 is driven to approach the supply position in that state, the operation arm 49 of the main boss member 46 contacts the stopper member 54 and is rotated counterclockwise. When the supply position is completely reached, each operating arm 49, that is, all the relay bodies 43 are in the supply posture in which the relay bodies 43 are inverted by 90 degrees, and the cucumber can be dropped and supplied onto the conveyor 8. When the driving means 44 is reversely driven from the above state and the relay body 43 is slightly returned to eliminate the interference with the stopper member 54, the biasing force of the torsion spring 51 causes each relay body 43 to automatically return to the mounting posture. become. Therefore, in the suction-adapted spacing state of the relay body 43 in which the spacing changing mechanism 45 is driven back and the boss members 46 contact each other, the connecting pin 49a is located at the front end of the elongated hole 50a, and even in this state, the screwing is performed. The relay body 43 is maintained in the mounting posture by the urging force of the reed spring 51.

10 to 12 show a series of action principle diagrams of the supply means A. Briefly explaining, FIG. 10 (a) shows the initial state, and the action body 11 is located above the storage box 1. However, the relay body 43 is located outside the front end of the storage box 1. In FIG. 10B, the action body 11 descends and the suction pad 1
When cucumber is adsorbed at 0, Fig. 10 (c)
Shows the state in which the cucumber is picked up and the cucumber is lifted. FIG. 11A shows a state in which the driving means 44 is driven to move the closely spaced relay bodies 43 to the receiving position.
Is a state in which the suction pump 13 is stopped and the suction cucumber drops and is delivered to the relay 43.

FIG. 11C shows a state in which the relay body 43 is moving toward the conveyor B by making full use of the driving means 44 and the gap changing mechanism 45. At this time, the acting body 11 is Begins to move towards the adsorption point.
FIG. 12A shows a state in which the relay body 43 is rotationally driven by the contact between the stopper member 54 and the operation arm 49 of the main boss member 46 at the supply position and the cucumber is supplied to the conveyor B (stopper). The driving means 4 is configured so that the inversion driving by the member 54 is simultaneously performed in all the relay bodies 43.
The expansion action of the interval changing mechanism 45 is completed slightly earlier than that of 4). Lastly, the acting body 11 is moved downward, and the next adsorption operation is started.

Next, in FIG. 12B, the relay 4
3 is in the middle of returning from the supply position, and the action body 11 that has adsorbed the cucumber is moving upward. Then, as shown in FIG. 12C, the position immediately below the adsorbed cucumber is determined. The relay body 43 that has been returned to the receiving position is returned to the close spacing, and is thereafter repeated from the state of FIG. The receiving position of the acting body 11 is changed little by little as it moves back and forth and left and right in the storage box 1.

The belt conveyor B includes the front and rear wheels 15 and 1.
6, a conveyor belt 8 wound around these, and a drive source 26 such as an electric motor. By placing and transferring the cucumber on the conveyor belt 8, the cucumber can be conveyed without dropping the warts on the surface of the cucumber. Further, in order to make it easier to maintain the posture adjusted by the relay body 43, it may be convenient to appropriately form a ridge orthogonal to the belt moving direction on the belt surface.

The image processing means C is constructed by disposing a CCD (charge coupled device) camera 9 on an overhang portion of a support tower 19 provided at an intermediate position in the conveying direction of the belt conveyor B, and on the conveyor. The cucumber is photographed from above and its shape and size are recognized.

The selecting means D is constructed by arranging four selecting actuators (extendable cylinders, etc.) 20 to 23 in parallel in the longitudinal direction of the belt at a position near the side of the belt conveyor B. The first cylinder 20 that extrudes a cucumber that is linear and has a predetermined length or more, the second cylinder 21 that extrudes a cucumber that is linear and has a predetermined length or less, and the curved shape has a predetermined length The third cylinder 22 for extruding the above-mentioned cucumber and the fourth cylinder 23 for extruding a cucumber having a curved shape and having a predetermined length or less are configured.

Then, the supplying means A, the drive source 26 of the belt conveyor B, the image processing means C, and the cylinders 20 to 2 are used.
Each of the control valve groups 24 for 3 is electrically connected to the control device 25. As a result, when the sorter is driven, the cucumbers in the storage box 1 are automatically sorted into four types of collected cucumbers and waste cucumbers without requiring human labor and are collected in the respective collection boxes 3 to 6 and 7. Of.

[Other Embodiments] Instead of the contact structure with the stopper member 54 just before the driving of the driving means 44 is finished, FIG.
As shown in FIG. 3 and FIG. 14, the time difference supply means E may be provided by a cam member (corresponding to an acting body) 59 that slides toward the storage box 1 and a connecting pin 49a of each operation arm 49. That is, when the cam member 59 slides while the relay body 43 is at the supply position, the operation arm 49 on the lower side in the transport direction is sequentially rotated, and the operation arm 49 of the main boss member 46 is the last. Therefore, the time difference causes the gap between the cucumbers on the conveyer conveyor B to be further widened, which can contribute to ensuring the processing in the image processing means C.

For example, the main boss member 46 is provided with a dedicated drive source such as a geared motor that is rod-connected to the operation arm 49 of the main boss member 46, and the relay body 43 is expanded by the interval changing mechanism 45 to a supply compatible interval. Alternatively, the rotating mechanism 57 may be configured to reversely drive. Further, the driving means 44 may be configured by driving a chain or a belt, or a gap changing mechanism 45 for changing the gap between the relay bodies 43 by another mechanism may be used, and various structures can be considered.

Further, immediately after receiving the cucumber at the receiving position shown in FIG.
Alternatively, the feeding means A may be configured so that the spacing between the relay bodies 43 is expanded from the close spacing to the feeding matching spacing by driving the driving means, and then the driving means 44 is used to move to the feeding position. This corresponds to the configuration of claim 2 and the interval changing mechanism 45 constitutes the enlarging mechanism 60.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
