Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a fruit and vegetable aligning device for aligning fruits and vegetables, and more particularly to a fruit and vegetable aligning device capable of aligning head and tail fruits and vegetables according to a predetermined setting.

[0002]

[Prior art]

 The fruits and vegetables that are harvested, such as carrots and eggplants, are often sorted by size and then packed in groups of several at retail stores. The packing work is carried out manually or by machines, but carrots etc. are transported by conveers one by one to this workshop. If they are not transported one by one in this way, the efficiency of manual packing work will deteriorate. In addition, it is assumed that they will be transported one by one when using machines. Therefore, it is necessary to have a device that feeds out many fruits and vegetables one by one and places them on the conveyor.

In recent years, in retail stores, in order to improve the appearance and improve the transportability, the fruits and vegetables such as carrots are packaged by staggering the heads of fruits and vegetables. There is more to do. In the case of packaging in this way, the packaging is done manually, or the fruits and vegetables are manually prepared and sent to the packaging machine.

[0004]

[Problems to be solved by the device]

 At present, it is difficult to increase the packaging mechanization rate because the direction of the head and tail of fruits and vegetables sent to the packaging process is not specified. An object of the present invention is to provide a fruit and vegetable aligning device for aligning the head and tail of fruits and vegetables and sending out the fruits and vegetables one by one.

[0005]

[Means for Solving the Problems]

 The vegetable and fruit arranging device according to the first aspect includes a sending-out unit, a gap adjusting unit, and a direction changing unit. The sending-out means sends out a large number of fruits and vegetables one by one. The interval adjusting means adjusts the distance between the continuous fruits and vegetables sent by the sending means. The direction changing means changes the direction of the head and tail of the fruits and vegetables that are sent with the distance adjusted by the distance adjusting means.

When fruits and vegetables are conveyed to the apparatus according to the present invention, these fruits and vegetables are delivered one by one to the interval adjusting means by the delivery means. The interval adjusting means adjusts the interval between fruits and vegetables that may be continuous to a predetermined distance. Then, the direction-changing means changes the direction of each fruit or vegetable to the determined head-to-tail direction. Here, since the interval between fruits and vegetables is adjusted by the interval adjusting means, it is possible to turn each of the fruits and vegetables into a predetermined direction by the direction changing means.

In this way, since the fruits and vegetables sent out from the device according to the present invention have head-to-tail directions determined one by one, the fruits and vegetables may be aligned in the packaging in the subsequent process. , You can alternate the heads of fruits and vegetables. According to a second aspect of the invention, in the apparatus according to the first aspect, the feeding means is a means including a main body, a rotary drum, a bottom plate, and a drive unit. The rotary drum is rotatably supported by the main body in a state where the rotary shaft is inclined with respect to a horizontal ground surface, and has a cylindrical portion and at least one projecting portion. The projecting portion projects inward from the inner peripheral surface of the cylindrical portion. The bottom plate is disposed substantially perpendicular to the rotation axis of the rotary drum, and is fixed to the main body so as to close one end of the lower side of the rotary drum. The bottom plate has an opening through which fruits and vegetables can pass. The drive unit rotates the rotary drum.

When the feeding means of the present invention is operated, the drive unit rotates the rotary drum, and the rotary drum rotates with respect to the main body and the bottom plate. Many fruits and vegetables are carried in from the upper side of the rotating drum. Many fruits and vegetables are temporarily stored here. The fruits and vegetables in the rotating drum rotate according to the rotation of the rotating drum, and one of them is caught by the protrusion protruding inside the cylindrical portion and is carried to the opening of the bottom plate. Then, the fruits and vegetables scratched on the protruding part are discharged from the opening of the bottom plate and conveyed to the subsequent process by a conveyor or the like installed under this opening.

Conventionally, fruits and vegetables are arranged on the conveyor by combining a plurality of conveyors, but here, fruits and vegetables are stored in the internal space of the rotating drum. Therefore, the space occupied by the device is reduced. Even if the fruits and vegetables caught in the protrusion are not discharged from the opening, the fruits and vegetables return to the inside of the rotating drum and do not go out of the rotating drum. This prevents the fruits and vegetables from spilling from the delivery means, and reduces the need to provide a separate means for returning the spilled fruits and vegetables, and even when providing them, they are small.

Further, here, it is possible to store fruits and vegetables in the rotary drum to some extent, and since the sending-out means functions as a buffer, a line such as a step of a distance adjusting means or a direction changing means which is a pre-process or a post-process. Easy to respond to stop and deceleration. According to a third aspect of the invention, in the apparatus according to the first or second aspect, the direction changing means includes a head-tail recognition mechanism and a reversing mechanism. The head-to-tail recognition mechanism is a mechanism that recognizes the direction of the head and tail of fruits and vegetables. The reversing mechanism is a mechanism provided on the downstream side of the head-to-tail recognition mechanism and can reverse the direction of fruits and vegetables.

The fruits and vegetables that are sent one by one at a predetermined interval by the sending-out means and the interval adjusting means are first recognized by the head-tail recognition mechanism of the direction changing means. Examples of the head-to-tail recognition mechanism include a mechanism that measures the height of fruits and vegetables being conveyed in time series by a sensor, a mechanism that determines the head and tail by imaging the fruits and vegetables with a camera and processing the shadows, and a load cell. Based on this, a mechanism that determines the head and tail by measuring the weight of the front and back of fruits and vegetables can be considered. Next, based on the result of this head-to-tail determination, the reversing mechanism reverses the direction of the fruits and vegetables, or the fruits and vegetables are sent out without activating the reversing mechanism.

Here, for example, when it is desired to align the heads of fruits and vegetables, it is sufficient to control the reversing mechanism so that the fruits and vegetables always have a fixed orientation, and when it is desired to alternate the heads and tails of fruits and vegetables with every other head. Control may be performed so as to determine whether or not the inversion mechanism is required to be operated based on the result of the tail recognition mechanism determination and the direction of the head and tail of the fruit or vegetable one before. In this way, fruits and vegetables are delivered in the direction of the fruits and vegetables according to the packaging needs.

According to a fourth aspect of the present invention, in the apparatus for aligning fruits and vegetables according to any one of the first to third aspects, the gap adjusting means operates at a first conveyor and at a speed higher than that of the first conveyor. It has two conveyors. The fruits and vegetables sent out one by one from the delivery means are first placed on the first conveyor and conveyed, and then the fruits and vegetables are transferred from the first conveyor to the second conveyor and conveyed.

Here, the fruits and vegetables sent from the sending means are first placed on the first conveyor having a slow speed. Therefore, the phenomenon of repelling fruits and vegetables as seen at high speeds can be suppressed. Moreover, since the second conveyor is faster than the first conveyor, even if the gap between fruits and vegetables is small on the first conveyor, the gap is large on the second conveyor. It is also possible to set an arbitrary interval by adjusting the speed of the second conveyor. In this way, fruits and vegetables are sent out with a predetermined interval.

According to a fifth aspect of the present invention, there is provided an apparatus for aligning fruits and vegetables according to any one of the first to fourth aspects, further comprising packaging means. The packaging means packs a plurality of fruits and vegetables sent in a predetermined head-to-tail direction by the direction changing means. Here, a packaging means is included in the fruit and vegetable aligning device to automate the process of packaging a large number of fruits and vegetables conveyed by the fruit and vegetable aligning device in an arbitrarily set direction.

[0016]

[Embodiment of the invention]

 FIG. 1 shows a fruit and vegetable alignment system (a fruit and vegetable aligning device) 1 according to an embodiment of the present invention. The fruit and vegetable alignment system 1 has a large number of carrots 8 carried by the belt conveyor 90 from the previous process, one by one in the longitudinal direction of the carrots 8 and the head and tail directions are reversed every other one. In this system, the package is sent to the conveyor 82 of the packaging device 80 in the subsequent process. The fruit and vegetable alignment system 1 is mainly composed of a feeding device (feeding means) 101 for feeding a large number of carrots 8 one by one, and an interval adjusting device for further spacing the carrots 8 with the carrots 8 oriented in the longitudinal direction ( An interval adjusting means) 20 and a direction changing device (direction changing means) 40 that recognizes the head and tail of the carrot 8 and changes the direction so that the head and tail of the carrot 8 can be set as desired. It

The delivery device 101 will be described in detail later. The gap adjusting device 20 is operated by a motor 33 and a first V-shaped conveyor (first conveyor) 21 in which two belt conveyors 22 operated by a motor 23 are inclined as shown in FIG. As shown in FIG. 2, the two belt conveyors 32 are configured to be inclined and the second V-type conveyors (second conveyors) 31 whose lower ends are brought close to each other. The speed of the belt conveyor 32 of the second V-shaped conveyor 31 is set to be higher than the speed of the belt conveyor 22 of the first V-shaped conveyor 21. The upstream end of the first V-type conveyor 21 is arranged below the lower end of the delivery chute 106 of the delivery device 101 described later, and the upstream end of the second V-type conveyor 31 is below the downstream end of the first V-type conveyor 21. Placed on the side. Both V-type conveyors 21 and 31 are horizontally fixed to a frame 10 installed on a horizontal grounding surface 9 of a factory or the like.

The direction changing device 40 includes a belt conveyor 61, a head-to-tail recognition mechanism 41, and a reversing mechanism 51. The belt conveyor 61 is operated by a motor 63, the upstream end of which is arranged below the downstream end of the second V-shaped conveyor 31 and is horizontally fixed to the frame 10. The belt conveyor 61 has a horizontal upper surface on which the carrot 8 is placed.

The head-to-tail recognition mechanism 41 mainly includes a light emitting side sensor 42a to 42d and a light receiving side sensor 43a to 43d which face each other across the belt conveyor 61 as shown in FIG. 2, and a recognition unit (not shown). Consists of. The recognizing unit is provided in the control box 70, and provides information on whether or not the light receiving side sensors 43a to 43d receive light from the light projecting side sensors 42a to 42d in time series, that is, for a predetermined time (for example, 0. Enter every 05 seconds) to recognize whether the carrot 8 is being transported head-first or caudally. This information recognized by the recognition unit is sent to the control unit (not shown) in the control box 70. An operation panel is attached to one surface of the control box 70 so that the operator can input a delivery pattern of the carrot 8 in response to a package request. The control unit sends an operation command to the reversing mechanism 51 according to the input sending pattern and the information from the recognition unit.

The reversing mechanism 51 is a mechanism capable of reversing the head-to-tail direction of the carrot 8, and operates in response to a command from the control unit in the control box 70. The reversing mechanism 51 mainly comprises a fruit and vegetable side holder 52 and a motor 53 with a brake. The fruit and vegetable side part holder 52 extends upward from the central part of the connecting plate 52b, two side plates 52a provided with a size slightly larger than the width of the carrot 8, a connecting plate 52b connecting the upper parts of both side plates. The rotary shaft 52c. The length of the side plate 52a in the carrying direction is substantially equal to the length of the carrot 8. The rotating shaft 52c is fixed to the shaft of the motor 53. In this reversing mechanism 51, the motor 53 stops half-rotation in response to a command from the control unit. Note that this half rotation stop is performed via a control unit by a rotation amount detection mechanism (not shown).

The packaging device 80 is installed such that the upstream end of the conveyor 82 is arranged below the downstream end of the belt conveyor 61 of the direction changing device 40. Next, the operation of the fruit and vegetable alignment system 1 will be described. When a large number of carrots 8 are conveyed to the feeding device 101 by the belt conveyor 90 from the previous step, the carrots 8 are fed one by one to the interval adjusting device 20 by the feeding device 101 described later.

In the interval adjusting device 20, the carrots 8 sent out one by one are first placed on the first V-shaped conveyor 21 and conveyed, and then the carrot 8 is transferred from the first V-shaped conveyor 21 to the second V-shaped conveyor 31. Transferred and transported. Here, since the carrot 8 delivered from the delivery device 101 is first placed on the first V-shaped conveyor 21 having a low speed, the phenomenon of repelling the carrot 8 as seen when the speed is high is suppressed. Further, since the second V-type conveyor 31 is faster than the first V-type conveyor 21, even if the gap between the carrots 8 on the first V-type conveyor 21 is small, the gap on the second V-type conveyor 31 is large.

Then, the carrots 8 sent one by one with a predetermined interval are transferred from the second V-shaped conveyor 31 to the belt conveyor 61 of the direction changing device 40. Next, when the carrot 8 passes through the head-to-tail recognition mechanism 41, it blocks the light emitted from the light emitting side sensors 42a to 42d to the light receiving side sensors 43a to 43d. The recognition unit of the head-and-tail recognition mechanism 41 inputs and analyzes this blocking state at every minute time, and thus the carrot 8 also recognizes the head-to-tail direction. When this head-to-tail direction information is sent to the control unit in the control box 70, the control unit, based on the set sending pattern of the carrot 8, sets the head of the carrot 8 sent one before. In consideration of the direction of the tail, the rotation command is issued to the reversing mechanism 51 in time. The carrot 8 can be sent out in a pattern in which, for example, when the heads of the carrot 8 are to be aligned, the carrot 8 always has a fixed orientation, and when the heads and tails of the carrot 8 are to be alternated, the patterns of the carrots 8 are alternated. The turn etc. is set.

In the reversing mechanism 51, in response to a command from the control section, the fruit and vegetable side holder 52, which is positioned so as to surround the shaft of the motor 53 and both sides of the carrot 8 fixed thereto, rotates half a turn. As a result, the carrot 8 that has passed through the head-to-tail recognition mechanism 41 is inverted when it passes through the inversion mechanism 51 when the orientation is opposite to the set head-to-tail orientation. Since the space between the carrots 8 is opened by the space adjusting device 20, it is easy for each carrot 8 to be reversed by the reversing mechanism 51 in a predetermined direction.

Then, the carrots 8 that have passed through the reversing mechanism 51 and have been sent out one by one according to the set-out sending pattern are transferred to the conveyor 82 of the packaging device 80. In the packaging device 80, the carrots 8 sent out from the fruit and vegetable alignment system 1 have head-to-tail directions determined one by one, so that the packaging can be easily performed by a machine.

Next, the structure of the delivery device 101 will be described in detail. As shown in FIGS. 3 and 4, the feeding device 101 mainly includes a main body 102, a rotating drum 103, a bottom plate 104, a driving unit (driving means) 105, and a feeding chute 106. . The main body 102 includes a lower main body 121 installed on the ground plane 9 and an upper main body 120 whose one end is attached to the lower main body 121 via a hinge 122 so as to be rotatable and inclined. The upper body 120 can adjust the inclination with respect to the lower body 121 within a predetermined range by changing the tightening of an adjusting bolt 120a provided on the other end side.

The drive unit 105 is fixed to the upper main body 120 and rotates the rotary drum 103, and mainly includes an inverter-controlled motor 105a, a sprocket 105b, a roller chain 105c (see FIG. 4), and a shaft 105d. , A roller 105e, and a bearing 105f. The motor 105a and the four bearings 105f are fixed to the upper body 120. Each of the two shafts 105d is supported by two bearings 105f, and a sprocket 105b is fixed to the lower end thereof. As shown in FIG. 4, the sprocket 105b fixed to the shaft 105d and the sprocket 105b fixed to the shaft of the motor 105a are connected by a roller chain 105c. Two rollers 105e are fixed to each shaft 105d.

As shown in FIGS. 6 and 7, the rotary drum 103 is composed of a drum body 103a, a lower end supporting member 103b, and a belt-shaped disc 103c. The drum body 103a is formed by adhering a resin material such as vinyl chloride inside a thin steel plate formed into a hollow cylindrical shape. At the lower end of the drum body 103a, a metal mounting protrusion 103d (protruding portion) that protrudes from the inner peripheral surface toward the inner peripheral side is provided. Eight mounting protrusions 103d are provided at equal intervals in the circumferential direction, and the intervals are longer than the length of the carrot 8 (see FIG. 5). Then, a cushioning ball 130 (protruding portion) is attached so as to cover the mounting projection 103d. The buffer ball 130 is a spherical member made of resin, has a hole that fits in the mounting projection 103d, and is attachable to and detachable from the mounting projection 103d. The diameter of the buffer ball 130 is smaller than the width dimension of the carrot 8. The lower end support member 103b has a pipe flange shape in which the diameter of the outer peripheral surface of the drum body 103a is the diameter of the inner peripheral surface, and the flange portion directly intersects the surface of the drum body 103a. The belt-shaped disc 103c is a member arranged corresponding to the position of the roller 105e and abutting on the roller 105e. The diameter of the inner peripheral surface is the diameter of the outer peripheral surface of the drum body 103a, and the outer peripheral surface of the drum body 103a. Fixed to. The belt-shaped disc 103c is a strength member of the drum body 103a, and has a thickness larger than that of the drum body 103a. In this rotating drum 103, the strip-shaped disc 103c is placed on the four rollers 105e, and the flange portion of the lower end support member 103b is supported by the wheels of the four casters 125 fixed to the upper main body 120. , Is supported by the upper main body 120. The rotating drum 103 rotates with respect to the upper main body 120 by the rotation of the roller 105e. The rotation axis is O-O in FIG. 3 and is inclined with respect to the ground contact surface 9.

As shown in FIG. 8, the bottom plate 104 has a substantially octagonal shape, and a notch 104 d is provided in the upper portion thereof. As shown in FIG. 8, the bottom plate 104 is arranged inside the wheels of the three casters 125 on the lower and side parts, and the wheels of the upper casters 125 are located in the cutouts 104d. Note that, in FIG. 8, the outer peripheral end of the flange portion of the rotary drum 103 is indicated by a two-dot chain line. The flange portion of the rotary drum 103 is supported by the caster 125 on the upper main body 120 while sandwiching the bottom plate 104. A gap smaller than the width of the carrot 8 is provided between the rotary drum 103 and the bottom plate 104. Further, as shown in FIGS. 5 and 8, the bottom plate 104 is located above the central portion of the portion of the bottom plate 104 surrounded by the intersection line when the drum main body 103a is projected on the bottom plate 104 and along the intersection line, The opening 104a is opened. The length of the opening 104a in the circumferential direction is longer than the length of the carrot 8 and the width in the radial direction thereof is larger than the width of the carrot 8. An introduction guide 104b is attached to the bottom plate 104 in a slanting downward direction from a portion near the inner periphery of the lower end of the opening 104a. The introduction guide 104b projects vertically from the bottom plate 104 by a length slightly shorter than the width of the carrot 8. The bottom plate 104 is fixed to the upper main body 120 by bolts 104f (see FIG. 3) inserted through bolt holes 104c provided at four places.

The delivery chute 106 is a cylindrical member fixed to the back surface (lower surface) of the bottom plate 104, and is attached to the position of the opening 104a. Next, the operation and advantageous effects of the delivery device 101 will be described in detail. When the motor 105a is operated, the rotation is transmitted to the shaft 105d by the sprocket 105b and the roller chain 105c, and the roller 105e rotates. Then, the roller 105e rotates the rotary drum 103 via the belt-shaped disc 103b. Since the rotating drum 103 is rotatably supported by the upper body 120 by the casters 125, the rotating drum 103 rotates about the rotation axis OO with respect to the upper body 120.

The large number of carrots 8 carried by the conveyor 90 is carried into the rotary drum 103 from the upper end of the rotary drum 103. A large number of carrots 8 will be temporarily stored here. The carrot 8 in the rotary drum 103 rotates according to the rotation of the rotary drum 103, and one of them is caught by the buffer ball 130 and is carried to the opening 104a. Then, the carrot 8 passes through the opening 104a, is discharged by the delivery chute 106, is placed on the first V-shaped conveyor 21 of the interval adjusting device 20 installed below the lower end of the delivery chute 106, and is conveyed.

Here, first, since the size and shape of the opening 104a and the buffer ball 130 are set according to the shape and size of the carrot 8, the carrot 8 is reliably delivered one by one. Secondly, in the prior art, a plurality of conveyors were combined to arrange the carrots on the conveyors, but in this feeding device 101, the carrots 8 are stored inside the rotary drum 103. Therefore, the space occupied by the delivery device 101 is small.

Thirdly, even when the carrot 8 caught on the buffer ball 130 is not discharged from the opening 104a, the carrot 8 returns to the inside of the rotary drum 103 and does not go out of the rotary drum 103. Fourth, the feeding device 101 can store the carrot 8 in the rotating drum 103 to some extent, and when the line stop or the deceleration occurs in the pre-process or the post-process, the sending device 101 functions as a buffer. Absorb some deviations.

Fifth, eight buffer balls 130 are provided in the circumferential direction, and eight carrots 8 can be sent out while the rotating drum 103 makes one rotation. Therefore, it is possible to send out the carrots 8 one at a time. Further, by controlling the number of rotations of the motor 105a by an inverter, it is possible to respond to the time pitch of the feeding required in the subsequent process.

Sixth, since the buffer balls 130 are arranged at the lower end of the rotating drum 103 near the bottom plate 104, the carrot 8 is easily caught, and when the number of the carrot 8 in the rotating drum 103 is small. The carrot 8 is surely caught on the buffer ball 130. Seventh, since the diameter of the buffer balls 130 is equal to or smaller than the width dimension of the carrots 8, when the buffer balls 130 hook the carrots 8, two or more carrots 8 are not caught. This prevents two or more carrots 8 from being discharged from the opening 104a at one time. Further, it is possible to prevent the carrot 8 from being caught in the side of the opening 104a because the carrot 8 does not fit in the right direction because the side part of the carrot 8 is caught.

Eighth, the introduction guide 104b reduces the degree to which another carrot 8 falling from the upper part of the one carrot 8 collides with the one carrot 8. Therefore, it is possible to reduce the possibility that another carrot 8 collides with the one carrot 8 hooked on the buffer ball 130 to release the one carrot 8 from being caught, and the one carrot 8 is opened. It is suppressed to change so that it is hard to be discharged from the.

Ninth, by changing the inclination of the upper main body 120, that is, the rotary drum 103 according to the type of the carrot 8 and the surface condition, it is possible to adjust the feeding smoothly. is there. Tenth, if the buffer ball 130 is damaged, only the buffer ball 130 can be replaced, so that it is not necessary to replace or repair the entire rotary drum 103. Further, since the buffer ball 130 is made of resin, it is possible to prevent the carrot 8 from being damaged. Since the mounting projection 103 is made of metal and fixed to the steel plate portion of the drum body 103a, it has sufficient strength against repeated load from the carrot 8. Further, a resin material, which is a cushioning material, is also attached to the inner peripheral surface of the drum body 103a that rubs against the carrot 8, so that the carrot 8 is also protected from scratches and the like.
