Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a roller conveyor that conveys a transported product such as a fruit or vegetable having a round outer shape, such as oranges, oranges, tomatoes, potatoes, etc., and more specifically, sequentially distributed during transport from a state in which transported products are supplied together, The present invention relates to a roller conveyor that carries out in a line-up state.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there are roller conveyors for transporting transported objects having a relatively round outer shape such as oranges, oranges, oranges, etc. (Japanese Patent Laid-Open Nos. 11-199033, 11-343024, 2000-177831).
[0003]
These roller conveyors form a conveyance path by arranging rollers in parallel along the left and right sides of the conveyor body, and facing the front ends of the rollers at the approximate center of the conveyance path. Then, by driving and rotating the left and right rollers respectively, the conveyed items collectively supplied to the starting end of the conveying path are moved toward the center of the conveying path, and are vibrated and oscillated during conveyance. In this configuration, the transported articles in the state are arranged in a line at the center of the transport path while being dispersed back and forth, and then transported one by one from the end of the transport path to a line such as a sorting step.
[0004]
The conventional roller conveyor described above forms a conveyance path by rotatably supporting a plurality of relatively small-diameter rollers arranged in parallel, and pulleys are provided on the base end sides of the rollers arranged in parallel on the left and right sides. The endless round belt is bridged between the pulley and the drive shaft provided along the lower part of the roller row, so that all the rollers on the left and right sides are driven and rotated.
[0005]
[Problems to be solved by the invention]
However, as described above, in the case where each of the left and right rollers is driven via an endless drive belt, the driving rotational force is generated by the contact between the numerous pulleys and belts of each roller and the drive shaft. Therefore, belt wear, dust generation and contact noise are generated, and frictional resistance due to belt contact inevitably occurs. Also, when many rollers are driven and rotated at the same time, a failure of one roller affects other roller driving, and may cause problems such as belt cutting and running.
[0006]
In addition, the above-described conventional roller conveyor requires two drive shafts on the left and right, pulleys provided on each roller, and a belt spanning between the pulleys and the drive shaft. The maintenance to keep up was also difficult. Furthermore, since a relatively large space is required to accommodate the drive mechanism, there is a problem that the apparatus becomes large.
[0007]
The roller conveyor according to the present invention supplies the rounded outer shapes such as oranges, oranges, potatoes and the like to the starting end of the conveyance path, distributes the articles in the middle of the conveyance, and arranges them in a line. While having the function of carrying out each one, the drive mechanism that causes wear, dust generation, contact noise, etc. is rationally simplified, downsizing of the device, reduction of manufacturing costs, and improvement of maintainability. Let it be an issue.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, the roller conveyor of the present invention has transport rollers arranged in parallel on one side and the other side of the conveyor body. These transport rollers are rotatably supported in a state in which the adjacent ends of the one and other transport rollers are alternately arranged in the transport direction at the approximate center of the transport path.
In addition, each of the conveying rollers on one side and the other side crosses the adjacent axial cores at the approximate center of the conveying path width in front view, thereby conveying from one side and the other side of the conveyor body. A substantially V-shaped conveyance path in front view that is inclined downward toward the approximate center of the path width is formed.
[0009]
On the other hand, a driven magnetic wheel is mounted and fixed in the vicinity of the intersecting portion of both the one side and the other side conveying rollers, and a long-axis driving magnetic wheel is disposed along the lower portion of each roller intersecting portion. And it is pivotally supported.
The drive magnetic wheels are supported in a state where the driven magnetic wheels are arranged in a line in the longitudinal direction in the vicinity of the roller intersection, and in a state where the shaft cores intersect substantially at right angles in a plan view. It is brought close to the outer peripheral surface, and the driven magnetic wheel is driven and rotated by the magnetic force of the driving magnetic wheel, so that the conveying rollers on one side and the other side constituting the conveying path are rotated in a predetermined direction.
[0010]
The driving magnetic wheel and the driven magnetic wheel used in the roller conveyor of the present application are configured in the same manner as those disclosed in JP-A-7-177724, JP-A-7-177725, JP-A-8-9625, and the like. To do. That is, in the driven magnetic wheel, NS bipolar zones are alternately arranged at a predetermined pitch or spirally along the outer peripheral surface thereof. Further, the driving magnetic wheel has NS bipolar zones spiraled along the outer peripheral surface thereof, and the helical pitch of this polar zone corresponds to the pitch of the NS bipolar zone of each driven magnetic wheel. As a result, the N pole band and the S pole band between the two magnetic wheels always try to maintain a state of attracting each other in the closest state. Therefore, when the drive magnetic wheel is driven and rotated, each driven magnetic wheel is driven and rotated by the above-described attractive force of the NS bipolar band.
[0011]
The one-side and other-side conveyance rollers constituting the conveyance path of the roller conveyor are rotated in a predetermined direction by driving and rotating in a state where each driven magnetic wheel is synchronized with the driving rotation of the driving magnetic wheel.
When transported objects such as mandarin oranges are fed together at the start end of the transport path in a state where both the one side and other side transport rollers are driven and rotated, these transported objects are made to have uneven road surfaces by the rotating transport rollers. It is conveyed while being vibrated appropriately as it moves.
As a result, the transported objects that have been gathered are dispersed back and forth due to vibration, and each transported object always tries to roll down toward the center of the transport path width, which is the lowest part, by the road surface inclined in a substantially V shape in front view. While colliding each other with matching objects, they are arranged in a line at the approximate center of the conveyance path that is the lowest part. And at the terminal of a conveyance path, a conveyance thing is carried out one by one to lines, such as a sorting process.
The description of claim 2 will be described together with the description of the embodiment.

[0014]
As described above, each shaft support 3 installed separately on the left and right sides has a bearing portion 3a that supports the support shaft 11 of the transport rollers 1a and 1b. The bearing portion 3a is formed in a hollow shape, and the support shafts 11 of the transport rollers 1a and 1b are inserted therein and are rotatably supported via a bearing 12. Also, the right support shafts 11 that are supported are extended toward the upper portion of the left frame a1, and conversely, the left support shafts 11 are extended toward the upper portion of the right frame a1. Put out. Note that the inclination angles of the two support shafts 11 are the inclination angles of one half and the other half of the transport rollers 1a and 1b. In the present embodiment, the inclination angles are set to approximately 15 degrees with respect to the horizontal. It is. In addition, you may change this inclination-angle as needed.
[0015]
The left and right frames a1 of the conveyor body a are each provided with a guide support material 9a, and a guide plate 9 is attached and supported at the tip end portion that is bent into a substantially rectangular shape. The guide plate 9 is a member that covers the left and right sides of the conveyance path b over its entire length, and is attached and supported at an angle somewhat larger than the inclination of the conveyance rollers 1a and 1b on both the left and right sides. The upper end sides of the conveyance rollers 1a and 1b on both the left and right sides are configured to enter under the side edge. During the operation, the left and right guide plates 9 installed as described above receive a conveyed product to be protruded outward from the conveying rollers 1a and 1b on the left and right sides, and roll down toward the center of the conveying path b. Function to return to the home position.
[0016]
The driven magnetic wheel 4 is inserted into the support shaft 11 via a collar 13, and is further press-fitted from one end of a roller body 14 having a hollow end, and the support shaft 11, the rollers 1a and 1b, and the driven magnetic wheel. 4 is configured to rotate integrally. Further, the roller body 14 of this embodiment is formed so that the diameter on the frame a1 side is somewhat larger.
The conveyance roller 1a arranged side by side on the right half of the conveyance path b and the conveyance roller 1b arranged side by side on the left side are arranged in the conveyance direction of the conveyance path b in the vicinity where the driven magnetic wheel 4 is provided in plan view. The crossing part of the right conveyance roller 1a and the left conveyance roller 1b is close to each other and rotates in a non-contact state (FIGS. 3 and 6).
[0017]
The left and right transport rollers 1a and 1b arranged as described above are crossed at the center of the transport path width in the front view (FIG. 2). A substantially V-shaped conveyance path b is formed that is inclined from the right side and the left side of the sheet toward the approximate center of the width of the conveyance path b.
In addition, a substantially long drive magnetic wheel 50 is pivotally supported immediately below the intersection in the front view of the transport rollers 1a and 1b.
In the drive magnetic wheel 50, the magnetic wheel 5 formed in a substantially cylindrical shape is sequentially fitted on the outer periphery of the core shaft 5a, and is attached and fixed at regular intervals along the shaft core of the core shaft 5a. Further, the driving magnetic wheel 50 is rotatably supported by a bearing body 6 provided at an appropriate interval along the lower portion of the core shaft 5a, and the outer periphery of each magnetic wheel 5 is a driven magnetic wheel 4 on both the left and right sides. It is comprised so that the state close | similar to the outer periphery may be maintained (FIG. 2, FIG. 3).
[0018]
As described above, each driven magnetic wheel 4 provided on the right conveyance roller 1a is fixed at a position shifted slightly downward from the center of the intersection of the conveyance rollers 1a and 1b (left side in FIG. 2) and magnetically. The vehicle 5 is held in a state of being applied to one half of the axial direction of the vehicle 5. (FIGS. 3 and 6). On the other hand, each driven magnetic vehicle body 4 provided on the left conveyance roller 1b is fixed at a position slightly inclined downward (right side in FIG. 2) from the intersection center of the conveyance rollers 1a and 1b, and the magnetic vehicle 5 It is hold | maintained in the state concerning one half part of the axial direction (FIG. 4-a). That is, the pair of left and right transport rollers 1a and 1b are driven and rotated by the magnetic force of one magnetic wheel 5. In the state described above, the axis of the magnetic wheel 5 and the axes of the left and right transport rollers 1a and 1b are orthogonal to each other in plan view.
[0019]
By the way, each magnetic wheel 5 constituting the drive magnetic wheel 50 is made of a permanent magnet such as an Mn-Al magnet, and an N-pole band 5n and an S-pole band 5s are spirally attached to a circumferential surface formed in a cylindrical shape. It is configured by magnetizing. On the other hand, the driven magnetic wheel 4 mounted on the left and right conveying rollers 1a and 1b, like the magnetic wheel 5 described above, spirals an N-pole band 4n and an S-pole band 4s on a cylindrical peripheral surface. Is magnetized.
In addition, each magnetic wheel 5 provided in the drive magnetic wheel 50 has NS bipolar poles 5n and 5S having a pitch, that is, a helical pitch, of the NS bipolar bodies 4n and 4s of the driven magnetic wheel 4 provided on the transport rollers 1a and 1b. It is made to correspond to both spiral pitches.
[0020]
Therefore, in the drive mechanism using the magnetic wheel as described above, the N pole band and the S pole bands 5n and 5s of each magnetic wheel 5 of the drive magnetic wheel 50, and the driven magnets of the left and right transport rollers 1a and 1b. The NS bipolar bodies 4n and 4s of the vehicle 4 always try to maintain the closest state by the attractive force due to the magnetic field.
That is, when the drive magnetic wheel 50 is driven and rotated, the range of the NS bipolar zones 5n and 5s formed in a spiral shape of each magnetic wheel 5 continuously moves in the axial direction of the magnetic wheel 5 as it rotates. To do.
[0021]
On the other hand, each driven magnetic wheel 4 is substantially perpendicular to the driving magnetic wheel 50 and has the NS bipolar zones 4n and 4s arranged alternately along the circumferential surface. The vehicle 5 sequentially moves and rotates following the spiral movement of the NS bipolar zones 5n and 5s.
As a result, the magnetic force of the drive magnetic wheel 50 acts on each driven magnetic wheel 4 to give a rotational force, and the left and right transport rollers 1a and 1b including the driven magnetic wheel 4 are driven to rotate in the same direction. Incidentally, when the drive magnetic wheel 50 is rotated in the reverse direction, each driven magnetic wheel 4 and the left and right transport rollers 1a and 1b are also rotated in the reverse direction.
[0022]
In the above-described embodiment, the drive magnetic wheel 50 is configured to have a substantially long shaft shape by disposing the cylindrical magnetic wheel 5 on the outer periphery of the core shaft 5a at a predetermined interval. The driving magnetic wheel may be configured by magnetizing the N pole band and the S pole band of a permanent magnet at a predetermined helical pitch on the peripheral surface of the driving magnetic wheel formed in one long axis.
Further, along the peripheral surface of each driven magnetic wheel, the N pole band and the S pole band of the permanent magnet are alternately provided. Each driven magnetic wheel is pivotally supported with its axis intersecting the drive magnetic wheel at a right angle or obliquely and its peripheral surfaces are close to each other in a non-contact state.
[0023]
Moreover, you may comprise the driven magnetic wheel which rotates a conveyance roller as shown in FIG. 4-b. This driven magnetic wheel 4 ′ is obtained by alternately magnetizing N poles 4n and S poles 4s along the peripheral surface of the driven magnetic wheel. The driven magnetic wheel 4 ′ provided on the transport roller is driven and rotated in the same manner as the driven magnetic wheel 4 described above even if the N pole and the S pole are arranged as described above.
A pulley 7a is attached to one end of the core shaft 5a of the drive magnetic wheel 50 described above, and the pulley 7a and a pulley 7b attached to the output shaft 8a of the drive motor 8 installed on the bottom plate a2 of the conveyor body a. An endless belt 7c is installed between them. Thus, the drive magnetic wheel 50 is configured to be driven to rotate by driving the drive motor 8.
[0024]
FIG. 7A shows the difference in rotational speed between the conveyance rollers 1a and 1b on the left and right sides constituting the conveyance path b. The roller conveyor A described above is set so that the rotation speeds of the left and right transport rollers 1a and 1b are the same in the range of the starting end. The left transport roller 1b is set so that the rotational speed in the range b2 from the start end to the end end is somewhat faster than the transport rollers 1a and 1b in the range b1 at the start end of the transport path b. Further, the range b3 at the end of the transport path b is set so that the rotational speeds of both the left and right transport rollers 1a and 1b are the same as the above-described range b2. In addition, increase / decrease in the rotational speed of the conveyance rollers 1a and 1b is performed by changing the pole number of a driven magnetic wheel or a drive magnetic wheel.
[0025]
As described above, when the round conveyance objects such as oranges and oranges are collectively supplied to the start end b1 of the conveyance path b by making a difference in rotational speed between the left and right conveyance rollers 1a and 1b, the conveyance object Shifts to the next range b2 in a substantially unchanged state. In the range b2, since the rotation speed of the conveyance roller 1b in the left half is fast, an urging force that swings in the width direction of the conveyance path b is applied to the moving conveyance object. Thereby, the conveyed product supplied in a collective state can be reliably dispersed within the range b2 in the conveyance path b. Further, in the range b3 of the end portion of the transport path b, the speeds of the left and right transport rollers 1a and 1b are maintained at a high speed, so that the transported objects that have reached the end portion can be reliably transported one by one.
[0026]
The difference between the rotation speeds applied to the left and right transport rollers 1a and 1b and the range thereof are not limited to those described above, and may be set arbitrarily. For example, as in the roller conveyor A ′ shown in FIG. 7B, the ranges b1 to b6 having a high rotation speed are alternately arranged on the left and right on the conveyance path b, thereby carrying out the dispersion of the conveyed product in a meandering manner. It is also possible to increase the value.
[0027]
Next, the operation of the roller conveyor A configured as described above will be described.
As shown in FIG. 5, a supply conveyor d <b> 1 that conveys oranges and oranges is installed at the beginning of the roller conveyor A. Further, a sorting conveyor d2 for sorting the transported items is connected to the end of the transport path b.
Then, when the conveyance rollers 1a and 1b on both the left and right sides are driven and rotated by the drive rotation of the drive magnetic wheel 50, when a transported object such as a mandarin orange is supplied to the start end of the transport path b, These transported materials move to the intermediate portion of the transport path while being appropriately vibrated so as to move on the uneven road surface by driving rotation of the rotating transport rollers 1a and 1b.
[0028]
At this time, the transported objects that are gathered are dispersed back and forth due to vibrations when moving on the transport rollers 1a and 1b, and each transported object becomes the lowest part due to the road surface of the transport path inclined in a substantially V shape in front view. It always tries to roll down toward the center of the width of the conveyance path b. Further, as described above, a dispersion force due to a speed difference between the left and right transport rollers 1a and 1b also acts on the transported object.
The transported objects are arranged in a line along the center of the transport path b serving as the lowest part while colliding with adjacent objects. At the end of the transport path, the transported articles are reliably supplied one by one toward the start end of the sorting conveyor d2 that communicates with the sorting process and the like.
[0029]
Next, a description will be given roller conveyor A '' shown boiled FIG.
This roller conveyor A ″ is configured in the same manner as the roller conveyor A described above, but is made of aluminum that is extruded into a predetermined cross-sectional shape on the bottom surface of a frame a3 bent into a substantially U-shaped cross section. The support substrate e is attached and fixed. The support base e is configured by screwing the shaft support 3 'of the left and right transport rollers 1a and 1b so as to be slidable.
The roller conveyor A ″ configured as described above uses the support substrate e formed by extruding aluminum as an attachment member for each shaft support 3 ′ and the drive magnetic wheel 50. The vehicle mounting structure can be integrated into a simple structure, and there are advantages that the manufacturing cost can be reduced and that disassembly and assembly operations can be easily performed.
[0030]
Next, the roller conveyor A2 shown in FIG. 9 will be described.
The roller conveyor A2 is configured in the same manner as the roller conveyor A ″ described above, but the driven magnetic wheel 4 provided on the left and right conveying rollers 1a and 1b is connected to the lower end side of the support shaft 11 of the conveying rollers 1a and 1b. It extends and is fitted and fixed here. The drive magnetic wheels 50 are arranged directly below the driven magnetic wheels 4 so that the axis of each driven magnetic wheel 4 and the axis of the drive magnetic wheels 50 are orthogonal to each other.
A pulley 7 a is disposed at the end of the drive magnetic wheel 50, and a tension pulley 7 d is disposed at the lower center of the drive magnetic wheel 50. Further, a drive pulley 7b is attached to the output shaft 8a of the drive motor 8, and an endless belt 7c is wound around these pulleys 7a, 7b and 7d.
[0031]
The roller conveyor A2 configured as described above is driven and rotated by the drive motor 8 being driven to synchronize both drive magnetic wheels 50. Both drive magnetic wheels 50 drive and rotate the conveyance rollers 1a and 1b on the left and right sides. The roller conveyor A2 configured as described above has an advantage that the torque of each of the transport rollers 1a and 1b can be increased, and the mutual magnetic interference generated between the adjacent driven magnetic wheels 4 can be reduced.
[0032]
【The invention's effect】
Since the roller conveyor of the present invention is configured as described above, a round conveyance object such as a mandarin orange, orange, potato or the like is supplied to one end of the conveyance path in a state of being collected at the start end of the conveyance path. At this time, these conveyed items are conveyed while being appropriately vibrated by the conveying rollers on one side and the other side of the conveying path.
Further, the conveyance path constituted by both the one-side and other-side conveyance rollers is inclined in a substantially V shape when viewed from the front so that the approximate center of the conveyance path width is the lowest part. The transported objects supplied to the unit are gradually dispersed in the front-rear direction while adjacent objects collide with each other. At the same time when the conveyed product is dispersed, it is displaced toward the lowest part, and as the conveyance progresses, it is naturally settled and aligned in a line at the approximate center of the conveyance path that is the lowest part. Then, at the end of the transport path, the transported articles are supplied one by one to a line such as a sorting process to be connected next. That is, the roller conveyor of the present application can smoothly and surely distribute and align round conveyed objects such as oranges, oranges, and potatoes as described above with a simple structure.
[0033]
The roller conveyor according to the present invention is driven in a non-contact manner using a magnetic force generated between the driving magnetic wheel and a driving magnetic wheel transmitted from one driving magnetic wheel to a driven magnetic wheel provided on each transport roller. Because it is carried out in the state, there is no belt wear, dust generation, contact noise, or contact resistance as in the case of conventional conveyors that are driven and rotated using pulleys and round belts. The drive torque can be transmitted smoothly. That is, since one drive magnetic wheel can drive and rotate each of the conveyance rollers on one side and the other side, the structure can be simplified, the manufacturing cost can be reduced, and the space for installing the drive mechanism can be reduced. The roller conveyor can be reduced in size, and further, it is free from maintenance and is not cut or scraped like a conventional round belt.
In addition, because a difference in rotational speed is provided between the transport rollers on one side of the transport path and the other side of the transport path within a predetermined range in the transport path, round objects such as oranges and oranges are transported. By supplying the urging force that swings in the width direction of the conveyance path to the moving conveyance object due to the speed difference of the conveyance rollers in the middle of the conveyance of the conveyance object when being supplied collectively to the path, It is possible to more reliably disperse the conveyed objects conveyed in a collective state within a predetermined range.
[0034]
The roller conveyor according to claim 2 is the same as the roller conveyor according to claim 1 described above, and smoothly distributes and aligns round conveyed objects such as oranges and oranges with a simple structure, and is connected to the next line. The conveyed items can be supplied one by one toward the vehicle.
In addition, since each driven magnetic wheel is mounted in the vicinity of the end portion on the adjacent side where the one side and the other side conveying rollers intersect with each other, and the respective driving magnetic wheels are disposed along the lower part of the both driven magnetic trains, A larger torque can be secured, and the rotational speed can be set widely and easily when a difference in rotational speed is made between the conveying rollers on the one side and the other side.
In addition, because a difference in rotational speed is provided between the transport rollers on one side of the transport path and the other side of the transport path within a predetermined range in the transport path, round objects such as oranges and oranges are transported. By supplying the urging force that swings in the width direction of the conveyance path to the moving conveyance object due to the speed difference of the conveyance rollers in the middle of the conveyance of the conveyance object when being supplied collectively to the path, It is possible to more reliably disperse the conveyed objects conveyed in a collective state within a predetermined range.
