JP, 2009-113942, A

In addition to the first and second endless lines, the vertical transfer machine as described above requires a third endless line and connection parts to keep the transfer base and the connection parts always horizontal. . For this reason, there is a problem that the structure of the transfer machine becomes complicated.

The present invention has been made in view of the problems existing in such prior art. The object is to provide a transport device having a simple structure.

Hereinafter, the means for solving the above-mentioned subject and its operation effect are described.
The conveying device which solves the above-mentioned subject is provided with a pair of 1st ring bodies, a pair of 2nd ring bodies, a pair of endless line objects, and a conveyance member. The pair of first ring bodies rotate about the same axis disposed at the first position. The pair of second ring bodies rotate about the same axis disposed at a second position higher than the first position. The endless strips are respectively wound on the corresponding first and second corresponding ring bodies so as to mesh with the corresponding one of the first and second corresponding ring bodies. It is done. The transport member is mounted so as to be cantilevered on the pair of endless strips, and can support a transport.

According to this configuration, by rotating any one of the first and second ring bodies, the transport member circulates and moves around the first and second ring bodies together with the endless strip. In this case, the transport member is cantilevered by the pair of endless strips. For this reason, the transport member is reversed in the process of passing the first and second ring bodies. Therefore, extra parts such as chains are not required to keep the transport member horizontal at all times. Thus, the structure of the transfer device can be simplified.

In the above-mentioned conveyance device, it is preferable that a pair of the above-mentioned endless bars are arranged inside the movement path of the above-mentioned conveyance member.
According to this configuration, the length of the pair of endless strips can be shortened as compared with the case where the pair of endless strips are disposed outside the movement path of the transfer member.

The first pusher 21 pushes the empty case 15 in the transfer device 14 onto the corresponding first recovery conveyor 20 via the operation outlet 57 located in the second area 102 by the operation of the power source 52.

On the first floor 12, a second transfer conveyor 22 and a second collection conveyor 23 are disposed on the side opposite to the one side of the transfer device 14. The second transport conveyor 22 is a delivery position of the harvest S on the first floor 12, which is a shipping floor, from the middle position slightly lower than the second floor 16 in the transport device 14, the case 15 in which the harvest S is stored. (Not shown). The second recovery conveyor 23 transports the empty case 15 from the shipping location to the midway position of the transport device 14.

The second conveyer 22 is connected to the conveyer 14 via a shipping outlet 55 located in the first area 101 at the halfway position of the conveyer 14. The second recovery conveyor 23 is connected to the transport device 14 via a shipping port 54 located in the second area 102 at the halfway position of the transport device 14. The transport device 14 includes a second pusher 24 and a pressing mechanism 51 at a height position where the second transport conveyor 22 and the second recovery conveyor 23 are disposed in the vertical direction Z. The second pusher 24 is disposed in the first area 101 of the transfer device 14. The pressing mechanism 51 is disposed in the second area 102 of the transport device 14. A power source 53 for driving the second pusher 24 is connected to the second pusher 24. The second pusher 24 receives the harvest S from the inside of the transfer device 14 onto the second transfer conveyor 22 via the shipping outlet 55 located in the first area 101 by the operation of the power source 53. Push out. The pressing mechanism 51 pushes the empty case 15 from above the second recovery conveyor 23 into the transfer device 14 through the shipping entrance 54 located in the second area 102.

Next, the configuration of the transfer device 14 will be described in detail.
As shown in FIGS. 2 and 3, the transport device 14 includes a frame 25. The frame 25 is assembled in a substantially rectangular shape so as to form the entire apparatus. A pair of first ring bodies 26 is disposed at a first position which is a lower end portion in a central portion in the width direction X in the frame 25. The pair of first ring bodies 26 are disposed to be apart from each other and to face each other in the depth direction Y orthogonal to both the width direction X and the vertical direction Z. The pair of first ring bodies 26 rotate about the same axis extending along the depth direction Y.

A pair of second ring bodies 27 is disposed at a second position which is an upper end portion in a central portion in the width direction X in the frame 25. The pair of second ring bodies 27 are arranged to be apart from each other and to face each other in the depth direction Y. The pair of second ring bodies 27 rotate about the same axis extending along the depth direction Y. The pair of second ring bodies 27 is disposed at a second position higher than the first position at which the pair of first ring bodies 26 is disposed. Positions in the vertical direction Z correspond to the pair of first ring bodies 26 and the pair of second ring bodies 27.

The pair of second ring bodies 27 are connected by a shaft 28. The shaft 28 extends in the depth direction Y through the centers of the pair of second ring bodies 27. The pair of second ring bodies 27 integrally rotate with the shaft 28. The shaft 28 passes through the central portions of the pair of second ring bodies 27, and one end of the shaft 28 is connected to the drive unit 29. The drive unit 29 is configured by, for example, a motor. The drive unit 29 is fixed to the frame 25. Therefore, the drive of the drive unit 29 rotationally drives the pair of second ring bodies 27 together with the shaft 28. The drive unit 29 is drive-controlled by a control unit (not shown).

A pair of endless strips 30 are wound around the pair of first ring bodies 26 and the pair of second ring bodies 27 so as to mesh with each other. That is, one endless strip 30 is wound around one first wheel 26 and one second wheel 27, and the other endless rod is fixed to the other first wheel 26 and the other second wheel 27. 30 are wound.

In the present embodiment, the first and second

annular members

26 and 27 are embodied as sprockets, and the endless wire 30 is embodied as a chain.
As shown in FIGS. 3 and 4, a plurality of rectangular plate-shaped transport members 31 capable of supporting the case 15 are attached to the outside of the pair of endless strips 30. The transport member 31 has a first placement surface 58 and a second placement surface 59 located on the back surface of the first placement surface 58. Further, the conveying member 31 is attached to the endless wire 30 via a pair of attaching members 32. The transport members 31 are attached to the pair of endless strips 30 at substantially equal intervals in the longitudinal direction of the endless strips 30. That is, the transport member 31 is attached to the pair of endless strips 30 via the pair of attachment members 32 so as to straddle the pair of endless strips 30.

In this case, the transport member 31 is attached to the pair of endless strips 30 via the pair of attachment members 32 so as to be cantilevered in a substantially perpendicular manner to the pair of endless strips 30. . That is, the conveyance member 31 is attached to the pair of endless strips 30 via the pair of attachment members 32 so that only one side thereof is supported. Therefore, when the pair of endless rods 30 are circularly moved around the pair of first ring bodies 26 and the pair of second ring members 27 by the drive of the drive unit 29, the pair of endless rod bodies 30 is the conveying member 31. Placed inside the moving path of

As shown in FIGS. 4 and 5, a guide member 33 is provided in the frame 25 so as to extend in the vertical direction Z. The guide member 33 guides a straight portion of the endless wire 30 which does not mesh with the first and

second wheels

26 and 27. Each of the guide members 33 is provided with a recessed groove 34 which extends in the vertical direction Z and which accommodates the corresponding straight portion of the endless strip 30.

As shown in FIGS. 5 and 6, each endless strip 30 has a pair of substantially rectangular inner link plates 35, a pair of substantially rectangular outer link plates 36, a cylindrical bushing 37, and a cylindrical shape. And the roller 38 of FIG. The pair of inner link plates 35 face each other apart from each other. The pair of outer link plates 36 are arranged to sandwich the pair of inner link plates 35 from the outer side. The bush 37 alternately connects the pair of inner link plates 35 and the pair of outer link plates 36 rotatably at their ends. The roller 38 is rotatably supported by the bushing 37.

The bush 37 passes through the pair of inner link plates 35 and the pair of outer link plates 36. Both ends of the bushing 37 protrude outward beyond the pair of outer link plates 36. The bush 37 is rotatably supported by the pair of inner link plates 35 and is non-rotatably supported by the pair of outer link plates 36. A part of the roller 38 protrudes from both sides in the lateral direction of the pair of inner link plates 35 and the pair of outer link plates 36. Therefore, the straight portion of the endless wire 30 is accommodated in the groove 34 so that the roller 38 can contact both sides in the groove 34.

The mounting member 32 has an L-shaped plate shape. The mounting member 32 includes a fixing portion 40 and a mounting portion 41. The fixing unit 40 is fixed to the transport member 31. The attachment portion 41 is attached to the endless wire 30. The fixing portion 40 has a rectangular plate shape extending along the side surface extending in the width direction X of the transport member 31. The fixing portion 40 is fixed to the end portion of the conveyance member 31 in the depth direction Y by a plurality of (four in this example) bolts 42 in a state of being inserted into the inside of the conveyance member 31.

The attachment portion 41 has a substantially rectangular plate shape extending in the longitudinal direction of the endless wire 30. The mounting portion 41 has a circular hole 43 at one end in the longitudinal direction, and has an elongated hole 44 extending in the longitudinal direction at the other end in the longitudinal direction. That is, the attachment portion 41 has a hole 43 and a long hole 44 which are disposed apart from each other in the longitudinal direction. Headed pins 45 inserted into the corresponding bushings 37 of the endless wire 30 are slidably inserted into the holes 43 and the long holes 44 of the mounting portion 41, respectively.

A nut 47 is tightened to the tip of the pin 45 inserted into the hole 43 in a state where the washer 46 is screwed. In this case, the pin 45 inserted into the hole 43 is rotatable relative to the hole 43. A nut 47 is tightened to the end of the pin 45 inserted into the long hole 44 in a state where the washer 46 is screwed. A cylindrical sliding roller 48 is rotatably interposed between the pin 45 inserted into the long hole 44 and the long hole 44. In this case, the pin 45 inserted into the long hole 44 can slide along the long hole 44 via the sliding roller 48.

Therefore, the attachment portion 41 of the attachment member 32 is attached to the endless wire 30 through the pin 43 slidably inserted into the hole 43 and the long hole 44 in the hole 43 and the long hole 44. That is, the attachment members 32 are attached to the endless wire 30 at two different places in the longitudinal direction of the endless wire 30.

Next, the operation of the transport device 14 will be described.
When vertically transporting the empty case 15 and the case 15 containing the crop S by the transport device 14, first, the drive unit 29 is intermittently driven. Then, the pair of second wheel bodies 27 is intermittently rotated by the driving force of the driving unit 29. As a result, the pair of endless bars 30 intermittently circulate around the pair of second ring bodies 27 and the pair of first ring bodies 26 and the pair of first ring bodies 26 is intermittently rotated. .

As a result, as shown in FIG. 3, the transport member 31 located in the first area 101 is intermittently lowered, and the transport member 31 located in the second area 102 is intermittently raised. At this time, the transport member 31 located in the first area 101 is reversed in the process of moving so as to make a U-turn along the first ring body 26. The transport member 31 located in the second region 102 is reversed in the process of moving to make a U-turn along the second ring body 27.

Further, at this time, the attachment member 32 for attaching the conveying member 31 to the endless wire 30 also moves along with the endless wire 30 so as to make a U-turn along the first ring 26 and the second ring 27. In this case, as shown in FIGS. 4 and 5, the curvature of the endless wire 30 changes the distance between the two pins 45 for attaching the mounting member 32 to the endless wire 30. However, one of the two pins 45 can move within the slot 44. For this reason, the attachment member 32 can be smoothly moved along the first wheel body 26 and the second wheel body 27.

In addition, the case 15 is put in and out of the transport device 14 at the time of stopping when the pair of endless linear members 30 are moving intermittently. As shown in FIGS. 1 and 3, on the transport member 31 positioned in the first area 101, the case 15 containing the crop S is pressed from the top of the first transport conveyor 19 through the work loading opening 56. It is pushed in and put on. At this time, as shown in FIG. 3 and FIG. 5, the load of the case 15 containing the crop S is received by the roller 38 of the endless wire 30. However, the roller 38 rolls on the side surface of the recessed groove 34 of the guide member 33. For this reason, it is suppressed that the circulation movement of the endless linear body 30 is prevented by the load of case 15 which accommodated the crop S.

As shown in FIG. 1 and FIG. 3, the case 15 containing the harvest S on the transport member 31 is lowered to the shipping floor and onto the second transport conveyor 22 via the shipping outlet 55 by the second pusher 24. It is pushed out. On the transport member 31 positioned in the second area 102, the empty case 15 is pushed and loaded by the pressing mechanism 51 from above the second recovery conveyor 23 via the shipping / loading port 54. In this case, the transport member 31 supporting the case 15 containing the crop S in the first area 101 is reversed in the process of passing through the first ring 26 and moving to the second area 102.

For this reason, the conveyance member 31 sets the empty case 15 on the second placement surface 59 (see FIG. 3) located on the back surface of the first placement surface 58 supporting the case 15 containing the crop S. To support. The empty case 15 on the transport member 31 is raised from the shipping floor to the work floor and pushed out by the first pusher 21 onto the first collection conveyor 20 via the work outlet 57. Thereafter, the transport member 31 supporting the empty case 15 in the second area 102 is reversed in the process of passing through the second sprocket 27 and moving to the first area 101.

Next, the operation of the transfer device 14 will be described in detail from the viewpoint of the flow of transferring the case 15 containing the harvested material S from the work place to the shipping place.
In the second floor 16, the third floor 17, and the fourth floor 18, which are work floors, a case in which the harvest S on the first transfer conveyor 19 enters via the work loading port 56 located in the first area 101 15 are transported to the transport device 14. The case 15 is placed on the first placement surface 58 of the transport member 31 in the transport device 14. Thereafter, the case 15 is lowered to the position of the first floor 12, which is the shipping floor, in the first area 101 of the transfer device 14. On the first floor 12, the case 15 containing the harvested material S placed on the first placement surface 58 of the transport member 31 via the shipping outlet 55 located in the first area 101 is the second transport It is transported to the conveyor 22. In this way, the case 15 containing the harvested material S is transported from the work area on the work floor to the shipping area on the shipping floor.

Next, the flow of transporting the empty case 15 from the shipping location to the work location will be described.
On the first floor 12, which is a shipping floor, the empty case 15 on the second recovery conveyor 23 is transported to the transport device 14 via the shipping port 54 located in the second area 102. The case 15 is placed on the second placement surface 59 of the transport member 31 in the transport device 14. Thereafter, the case 15 ascends in the second area 102 of the transfer device 14 to any one of the second floor 16, the third floor 17, and the fourth floor 18, which are working floors. On any one of the work floors, the empty case 15 placed on the second placement surface 59 of the transport member 31 via the work outlet 57 located in the second area 102 is attached to the first recovery conveyor 20. It is transported. In this way, the empty case 15 is transported from the shipping location on the shipping floor to the work location on the work floor.

As described above, in the transport device 14 of the present embodiment, in the region (first region 101) on one side in the width direction X, the case 15 containing the crop S using the first placement surface 58 of the transport member 31 In the area on the other side in the width direction X (the second area 102), the empty case is conveyed using the second placement surface 59 of the conveyance device 31. Then, in the transfer device 14 of the present embodiment, the case 15 is transferred to the transfer device 14 via the work loading opening 56 or the shipping exit 55 provided in the region (first region 101) on one side in the width direction X By inserting and removing the case 15 with respect to the transfer device 14 via the work outlet 57 or the shipping inlet 54 provided in the other region (the second region 102) in the width direction X. We are trying to use space effectively.

According to the embodiment described above, the following effects are exhibited.
(1) The conveying device 14 is attached so as to be supported in a cantilever manner by the pair of endless strips 30, and includes the conveying member 31 capable of supporting the case 15. For this reason, the conveyance member 31 is reversed in the process of passing the 1st ring body 26 and the 2nd ring body 27. As shown in FIG. Therefore, it is not necessary to use extra parts such as a chain to keep the transport member 31 always horizontal without inverting it. Thereby, the structure of the conveyance apparatus 14 can be simplified. Further, in the transport member 31, the second placement surface 59 supporting the case 15 when rising is different from the first placement surface 58 supporting the case 15 when falling. Therefore, both mounting

surfaces

58 and 59 can be used properly. For example, one of the two mounting

surfaces

58 and 59 of the transport member 31 can support a wet product in water and, on the other hand, can transport a non-wet product.

(2) In the transport device 14, the pair of endless strips 30 are disposed inside the movement path of the transport member 31. For this reason, compared with the case where the pair of endless strips 30 are disposed outside the moving path of the transport member 31, the length of the pair of endless strips 30 can be shortened. In addition, since the pair of endless bars 30 is disposed inside the movement path of the conveyance member 31, the conveyance member 31 can be accessed from the outside of the movement path of the conveyance member 31.

(3) In the conveyance device 14, the conveyance member 31 is attached to the pair of endless strips 30 via the attachment member 32. The attachment members 32 are attached to the endless wire 30 at two different places in the longitudinal direction of the endless wire 30. For this reason, the conveyance member 31 can be stably attached to the endless wire 30.

(4) In the transport device 14, the mounting member 32 has the hole 43 and the elongated hole 44 extending in the longitudinal direction. The holes 43 and the long holes 44 are disposed apart from each other in the longitudinal direction of the endless strip 30. The attachment member 32 is attached to the endless wire 30 via a pin 45 slidably inserted into the hole 43 and the long hole 44 in the hole 43 and the long hole 44. For this reason, when the mounting member 32 is moved to make a U-turn along the first annular body 26 and the second annular body 27 together with the endless wire body 30, the pin 45 inserted in the hole 43 and the long hole 44 The pin 45 inserted into the long hole 44 can move within the long hole 44 even if the distance to the inserted pin 45 changes. Therefore, the mounting member 32 can be moved smoothly.

(5) The second wheel body 27 is at a higher position than the first wheel body 26. For this reason, the second wheel body 27 usually receives a larger load from the endless wire body 30 than the first wheel body 26. The conveyance device 14 of the present embodiment includes a drive unit 29 that rotationally drives the pair of second ring bodies 27. The second wheel body 27 is rotationally driven by the drive unit 29. For this reason, the driving force of the drive part 29 can be efficiently transmitted to the endless linear body 30 via the second wheel body 27.

(Modification example)
The above embodiment may be modified as follows.
The drive unit 29 may be disposed at the lower end portion of the frame 25 and the drive unit 29 may rotationally drive the first wheel body 26.

The mounting member 32 does not necessarily have to be attached to the endless strip 30 via the pin 45 slidably inserted into the hole 43 and the long hole 44 in the hole 43 and the long hole 44. For example, the mounting member 32 may be welded to the endless wire 30.

The mounting members 32 do not necessarily have to be attached to the endless wire 30 at two different places in the longitudinal direction of the endless wire 30. For example, the attachment member 32 may be attached at one place to the endless wire 30.

The conveying member 31 does not have to be attached to the endless wire 30 via the mounting member 32. That is, the mounting member 32 may be omitted and the conveying member 31 may be directly attached to the endless wire 30.

The endless wire 30 does not have to be disposed inside the movement path of the transport member 31. For example, the endless wire 30 may be disposed outside the movement path of the transfer member 31. In this case, the transport member 31 is attached to the inside of the endless wire 30 via the attachment member 32.

The transported object does not necessarily have to be the case 15.
The articles contained in the case 15 do not necessarily have to be the crop S.
The positions of the pair of first ring bodies 26 and the pair of second ring bodies 27 in the vertical direction Z may be shifted.

The pair of first ring bodies 26 and the pair of second ring bodies 27 may be any as long as they rotate the pair of endless strips 30 by rotation. In the present embodiment, the first wheel body 26 and the second wheel body 27 are embodied as sprockets, and the endless wire body 30 is embodied as a chain. For example, the first wheel body 26 and the second wheel body 27 may be pulleys. The striated body 30 may be a belt.

In the above embodiment, the floor connected to the shipping place is the first floor 12, and the floors connected to the work place are the second floor 16, the third floor 17, and the fourth floor 18.
