Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an agricultural product packaging apparatus, and more particularly, to an agricultural product packaging apparatus suitable for aligning long agricultural products such as carrots, radishes and the like and packaging them without damaging them.
[0002]
[Prior art]
Traditionally, ginseng and other long agricultural products such as carrots that are sorted from a sorting conveyor and transported by a drawer conveyor in a packaging facility such as carrots are simply put into a box and packed in a box like a mandarin orange. Or may fall apart vertically and horizontally, resulting in a poor fit in the box and an empty space. In particular, when the box is a deep cardboard box or the like, the tendency is strong, and there is a risk of damaging long agricultural products. Therefore, techniques for solving such inconveniences are disclosed in, for example, Japanese Patent Publication No. 7-76010, Japanese Patent Publication No. 7-23144, and Japanese Patent Publication No. 7-23143.
[0003]
Among these, the boxing method for long items such as carrots (referred to as boxing device A) disclosed in Japanese Patent Publication No. 7-76010 discloses that a partition plate body is detachably attached to a partition plate body lifting mechanism. By inserting the body lifting mechanism into the box, a plurality of compartments are formed in the box and packed. In addition, a method for packaging ginseng and other long objects (referred to as a packaging device B) using an automatic packaging device disclosed in Japanese Patent Publication No. 7-23144 is a partition plate that forms a plurality of compartments in a box. Are inserted and provided, and the box is inclined and packed. Furthermore, a partition plate with a movable flap for boxing of carrots and the like (referred to as a boxing device C) disclosed in Japanese Patent Publication No. 7-23143 is formed by a plurality of partition plates inserted into the box body. When a compartment is formed and a long object is boxed in the compartment, the drop impact is mitigated by a movable flap that can be rotated by an impact.
[0004]
[Problems to be solved by the invention]
However, in the packaging apparatus A, the provision of the partition plate body slightly improves the collapse of the posture of the long object at the time of boxing compared to the case without the partition plate body, but it is merely a compartment. This is a method of throwing a long object from above, so the drop distance of the long object in the box becomes long when the box is particularly deep, and the posture of the long object may change at the time of loading, The attitude (packing) is inferior and the commercial value is likely to be reduced. In addition, since the falling distance of a long object at the initial stage is relatively long, the next long object is dropped from a high position and collides with a long object that has already been charged. There are problems such as easy damage.
[0005]
Moreover, in the boxing apparatus B, since the long object itself is expected to roll when the long object is packed by the inclined box, the shape of the long object is constant, such as carrots. If it is not, the way of rolling is not constant, especially carrots with a bend are difficult to roll, it is difficult to obtain a good rolling state, and in the case of tapered long objects such as carrots, along the inclined surface There is a tendency that the thick end tends to face downward due to rolling, and the long object cannot be neatly arranged in the box, and it is difficult to obtain a good boxing posture. Moreover, since it is a system in which a long object is simply thrown into the compartment from above, similarly to the boxing apparatus A, there is a problem that the long object is easily damaged.
[0006]
Further, in the case of the packaging device C, since the impact due to the dropping is mitigated by the movable flap provided in a part of the compartment, the rebound of the long object is suppressed, so the base side and the tip of the movable flap On the side, the action of the movable flap is different even for the same long object, and depending on where the movable flap comes into contact, the rebound action by the movable flap is not constant depending on the orientation, size, shape, etc. of the long object, There is a problem that a stable package cannot be obtained because the posture is not fixed. Further, in the case of the boxing device C, the movable flap is rotated every time the long object is dropped. Therefore, when the movable flap is rotated, the long object is placed between the lower side of the movable flap and the vertical partition plate. There is a risk of pinching, the surface of a long object previously packed with the tip of the movable flap, or the long object at the initial stage of dropping that does not contact the movable flap partially provided in the compartment There is also a problem that long objects are easily damaged at the time of packing, such as the impact is not relieved.
[0007]
  The present invention has been made in view of such circumstances, and its purpose is to improve the boxing posture to increase the commercial value and to reliably prevent damage to agricultural products during boxing.AndAgricultural products can be thrown into the compartments and dropped in the compartments reliably and smoothly, improving the workability of the boxing work, and simplifying the configuration of the equipment itself to make it cheaper.obtainIt is to provide a boxing device for agricultural products.
[0008]
[Means for Solving the Problems]
  In order to achieve this object, the invention according to claim 1 of the present invention is provided so that it can be inserted into and retracted from a box waiting on the lower end side of a supply conveyor for conveying agricultural products, and the space in the box. Is a boxing device for agricultural products having boxing auxiliary means for sequentially packing boxes of agricultural products supplied by a supply conveyor for each section divided into a plurality of sections,AboveBoxing auxiliary meansA plurality of stages are provided in the middle of the box in the vertical direction, and can be rotated between a substantially horizontal state for receiving agricultural products supplied from the supply conveyor and a substantially vertical state for guiding the agricultural products downward step by step. And the shutter forms a wall surface for the compartment in the substantially vertical state.It is characterized by that.
[0009]
  By configuring in this way, the agricultural products conveyed by the supply conveyor are sent and dropped downward from the end side of the supply conveyor for each section in which the space in the box is divided into a plurality of sections, and the boxing assisting means It is put (supplied) into a box waiting at the lower end side of the supply conveyor. In this state, when the amount of agricultural products put into each section reaches a predetermined amount,A shutter that guides agricultural products step by step downwardBecause it has, produce to be put into each sectionshutterThen, once a predetermined amount is received, it can be packed while being guided downward. This makes it possible to shorten the natural fall distance in each section of agricultural products that are sent and dropped from the terminal side of the supply conveyor, so that the boxing posture of the agricultural products is stably aligned, and the agricultural products at the time of input into each section The impact can be mitigated and the damage is surely prevented.
[0010]
  Also,ShutterSince a predetermined amount of agricultural products can be received once on the shutter by the closing operation, and this agricultural product can be dropped downward by the opening operation of the shutter, the guide (moving) downward in the section of the agricultural products is simple configuration Can be done reliably and smoothly. In addition, the shutters provided in multiple stages in the vertical direction can guide the agricultural products to be input by a predetermined amount with a shorter drop distance, and even when the box is deep, the boxing posture is more stable and the agricultural products are damaged. Is more reliably prevented.
[0017]
  Also,Claim 2The described invention is characterized in that the agricultural product is a long product, and is transported horizontally and packed in a box at least at the terminal end side of the supply conveyor. By configuring in this way, even if it is an agricultural product that has a thick end and a narrow end such as carrots and the shape of which is not stable, by setting the direction alternately, for example, a more stable boxing posture Can be obtained, and the empty space in the box can be reduced to increase the storage rate of agricultural products.
[0018]

[0026]
Further, a fixed partition plate 22 and an upper shutter 23 and a lower shutter 24 as guide means are disposed in the elevating frame 21. As shown in FIG. 4, the fixed partition plate 22, the upper shutter 23, and the lower shutter 24 are provided along the transport direction e of the advancing / retreating conveyor 9, so that the lifting frame 21 is positioned in the cardboard box 11. At the boxing position, the inside of the cardboard box 11 is partitioned into four partition chambers 25a to 25d along the transport direction e.
[0027]
Further, as shown in FIGS. 3 and 4, an upper shutter opening / closing cylinder 27 and a lower shutter opening / closing cylinder 28 are arranged outside both side walls of the elevating frame 21 along the conveying direction e of the advance / retreat conveyor 9. Yes. For example, four upper shutter opening / closing cylinders 27 are provided along the conveying direction e. The base end side of the upper shutter opening / closing cylinder 27 is fixed to the upper end of the elevating frame 21 via a fixing rod 29 and the front end side thereof is connected to the upper stage via a link 30. It is connected to the shutter 23. Further, four lower shutter opening / closing cylinders 28 are provided outside the side wall opposite to the upper shutter opening / closing cylinder 27 of the lifting frame 21, and the base end side thereof is fixed to the upper end of the lifting frame 21 via a fixing rod 31. At the same time, the tip side is connected to the lower shutter 24 via a link 32.
[0028]
The upper shutter opening / closing cylinder 27 and the lower shutter opening / closing cylinder 28 operate, for example, in the following manner in response to control signals from a control device (not shown) to which the weighing machine 10 is connected. That is, the total weight of the frame 17, the lifting frame 21, the cardboard box 11, and the long agricultural product boxed in the cardboard box 11 placed on the weighing machine 10 is measured by the weighing machine 10, and the measured value is set in advance. When the predetermined value is reached, an opening signal is output from the control device to a predetermined upper shutter opening / closing cylinder 27, the corresponding upper shutter 23 is opened, and the subsequent measurement value exceeds the predetermined value by a predetermined amount. When the predetermined value is reached, an opening signal is output to a predetermined lower shutter opening / closing cylinder 28, and the corresponding lower shutter 24 is opened.
[0029]
Note that each of the four upper shutter opening / closing cylinders 27 and the lower shutter opening / closing cylinders 28 operates in sequence from the downstream side (the front side of the compartment 25a side) of the forward / backward conveyor 9 in the conveying direction E by the release signal. Is set to The upper shutter 23 opening / closing link 30 and the lower shutter 24 opening / closing link 32 are set to have different lengths.
[0030]
Then, one end in the width direction of the upper shutter 23 and the lower shutter 24 is fixed to a rotation pin 33 (see FIG. 3) fixed to the tip (lower end in the figure) of each of the links 30 and 32. The other ends of the shutters 23 and 24 are rotatably supported on the side wall of the elevating frame 21 via a rotation pin 34 (see FIG. 3). As a result, the upper shutter opening / closing cylinder 27 is actuated and the shaft advances downward, so that the upper shutter 23 rotates in the direction of the arrow in FIG. 4 to be substantially vertical, and the shaft is retracted upward. As a result, the upper shutter 23 rotates in the direction opposite to the arrow direction and becomes substantially horizontal. This operation is exactly the same for the lower shutter 24.
[0031]
In the above example, the upper shutter 23 and the lower shutter 24 of each of the compartments 25a to 25d are configured as a single opening type. However, as shown in FIG. 14, for example, the shutters 23 and 24 are configured as a double-opening type. Of course, it is also possible to configure.
[0032]
As shown in FIG. 2, the empty box supply unit 13 includes an empty box transfer conveyor 36 that transfers an empty cardboard box 11 and an extrusion cylinder device 37 that sets the empty cardboard box 11 at a boxing position. . Then, when the extrusion cylinder device 37 is operated and the shaft advances, the empty cardboard box 11 on the supply position of the empty box transport conveyor 36 is supplied and set to the boxing position (on the weighing machine 10), and the box packing is performed. The corrugated cardboard box 11 containing the long agricultural products after the boxing of the long agricultural products at the position is sent out on the delivery conveyor 14 from the boxing position.
[0033]
Next, an example of operation | movement of the said boxing apparatus 1 is demonstrated based on FIGS. First, an empty cardboard box 11 is set on the weighing machine 10, the shaft 18a of the elevating cylinder 18 is retracted, and the elevating frame 21 is set to the boxing position, and each compartment 25a-25d is set in the control device. For example, eight predetermined weight values for opening the upper shutter 23 and the lower shutter 24 are set.
[0034]
In this state, as shown in FIGS. 1 and 2, the carrot W conveyed by the keyboard conveyor 4 is on the chutes 5a and 5b whose front end side is inclined downward at a predetermined sorting position according to the equal class. Are discharged onto the belt conveyors 6a and 6b. At this time, since the chutes 5a and 5b are inclined at a predetermined angle, the heavy-weight end portion is directed downward while the carrot W descends along the inclined surface, and the direction of each carrot W is approximately Aligned in the same direction and sent out on the belt conveyors 6a and 6b.
[0035]
The carrots W are conveyed to the end side by the belt conveyors 6a and 6b, sent to the V-shaped belt conveyors 7a and 7b, and conveyed while being aligned at the deepest portion of the V shape by the V-shaped belt conveyors 7a and 7b. And sent to the belt conveyor 8. At this time, the two V-shaped belt conveyors 7a and 7b and the belt conveyor 8 are operated in synchronization as described above, so that the direction of the carrots W alternates between the bars 8a on the belt conveyor 8. Are placed in line.
[0036]
The carrot W thus supplied onto the belt conveyor 8 is sent downward from the end side of the belt conveyor 8 and falls, and the advance / retreat conveyor that moves forward in synchronization with the belt conveyor 8 is moving forward. 9 are sent and placed in the same direction as the direction on the belt conveyor 8. Then, the advancing / retreating conveyor 9 to which the carrot W is supplied between the crosspieces 9a moves forward and enters the elevating frame 21 through the opening 21a of the elevating frame 21 set at the boxing position, for example, as shown in FIG. Stop at position.
[0037]
The carrots W between the rails 9a of the advancing / retreating conveyor 9 that is transporting at this stop position are sent one by one downward from the end side 9b of the advancing / retreating conveyor 9 and fall down one by one, in the compartment 25a of the cardboard box 11 They are sequentially put on and stacked on the upper shutter 23 in the horizontal state (closed state). At this time, the fixed partition plate 22 is fixedly arranged at the upper part of the compartment 25a, and the fixed partition plate 22 is located above the upper surface lid portion of the cardboard box 11, and the terminal side 9b of the advancing and retracting conveyor 9 and the cardboard box. 11 is partitioned from the upper end, so that the carrot W sent from the end side 9b of the advance / retreat conveyor 9 is reliably guided into the compartment 25a.
[0038]
When a predetermined amount of carrot W is put into the compartment 25a, a weight (weight increase) corresponding to the number of carrots W is measured by the weighing machine 10, and the measured value is set in the control device in advance. When the minimum predetermined value of the eight predetermined values is reached, the upper shutter opening / closing cylinder 27 is activated by the opening signal from the control device, as shown by the two-dot chain line in FIG. The upper shutter 23 is opened in the direction of the arrow and becomes vertical. As a result, as shown in FIG. 6, a predetermined number of carrots W on the upper shutter 23 of the compartment 25a falls (moves) downward and is placed on the lower shutter 24 of the compartment 25a.
[0039]
In this state, the next predetermined number of carrots W are input from the advancing / retreating conveyor 9 as shown in FIG. 7, and when the weight is measured by the weighing machine 10 to become the second predetermined value, the lower shutter of the compartment 25a The opening / closing cylinder 28 is actuated to open the lower shutter 24. When the lower shutter 24 is opened, the lower shutter 24 is in a vertical state as shown in FIG. 8, and a predetermined amount of carrot W on the lower shutter 24 moves downward and is accommodated in a stacked state on the bottom surface 11 a of the cardboard box 11. (Boxed). As a result, a predetermined amount of carrot W is packed in the compartment 25a of the cardboard box 11, and at this time, the carrot W has an upper shutter 23 and a lower shutter 24 that form a wall surface of the compartment 25a in a vertical state, and a lifting frame 21. The state where movement in the front-rear direction and the like is regulated by the rear wall and the side wall is maintained.
[0040]
When a predetermined amount of carrot W is packed in the compartment 25a of the cardboard box 11, the advance / retreat conveyor 9 is then moved backward by one step and stopped at the position shown in FIGS. At this position, the carrot W is sent and dropped from the end side 9b downward by the transport operation of the advancing / retreating conveyor 9, so that a predetermined amount of carrot W is thrown on the upper shutter 23 of the compartment 25b of the cardboard box 11. Similarly to the compartment 25a, the upper shutter 23 is opened (moving the carrot W downward), the carrot W is thrown in, and the lower shutter 24 is opened (moving the carrot W downward) in the compartment 25b. A predetermined amount of carrot W is boxed. By performing this operation in the same manner for the compartment 25c and the compartment 25d sequentially, a predetermined amount of carrot W is boxed in all of the four compartments 25a to 25d as shown in FIG.
[0041]
In this state, the advancing / retreating conveyor 9 is retracted to the retracted position shown in FIG. 10 and the elevating cylinder 18 is actuated to raise the elevating frame 21 as indicated by an arrow to fix the fixed partition plate 22 from the cardboard box 11. The elevating frame 21 in which the upper shutter 23 and the lower shutter 24 are integrated is set at the retracted position shown in FIG. At this time, the lifting frame 21 can be easily removed from the cardboard box 11 by forming the upper shutter 23 and the lower shutter 24 with thin plates and appropriately setting the amount of carrot W packed in the cardboard box 11. Can be extracted.
[0042]
When a predetermined amount of carrot W is packed in the cardboard box 11 by raising (extracting) the elevating frame 21, the cardboard box 11 containing the carrot W operates the extrusion cylinder device 37 of the empty box supply unit 13 shown in FIG. As shown in FIG. 2, the empty cardboard box 11 is extruded onto the delivery conveyor 14 and conveyed to the end side by the conveyor 14. At the same time, the next empty cardboard box 11 is pushed and set at the boxing position as shown by the arrow in FIG. 2, and the carton W-containing cardboard box 11 sent to the delivery conveyor 14 is set in this empty cardboard box 11. A predetermined amount of carrot W is boxed.
[0043]
As described above, in the boxing device 1 of the above embodiment, the lifting frame 21 is lowered and inserted into the empty cardboard box 11 set at the boxing position by the operation of the lifting cylinder 18. The four compartments 25a-25d along the transport direction e of the advancing / retreating conveyor 9 are formed, and the upper shutter 23 and the lower shutter 24 are disposed in the compartments 25a-25d so that they can be opened and closed. Once the carrot W reaches a predetermined amount, the carrot W can be boxed while being guided stepwise downward by opening the shutters 23 and 24.
[0044]
As a result, the distance of the natural fall of the carrot W in the cardboard box 11 is shortened, the posture change of the carrot W at the time of the fall is prevented, and the carton can be packed in a stable posture in which the orientation is aligned. Value can be increased. Moreover, since the fall distance of the carrot W in the cardboard box 11 at the time of packing is short, even if the depth of the cardboard box 11 is deep, for example, the impact received by the carrot W at the time of dropping can be reduced. In addition, it is possible to reliably prevent carrot W from being damaged during packaging.
[0045]
In particular, the upper and lower shutters 23, 24 are provided as guide means, and each guides a predetermined amount of carrot W in a stepwise manner, so that the carrot W fall distance can be shortened. The boxing posture can be made more stable, and the carrot W can be more reliably prevented from being damaged. In addition, since the shutters 23 and 24 are horizontally arranged in substantially the entire areas of the compartments 25a to 25d and receive all the predetermined amount of carrot W, the carrots W are damaged at the tips of the shutters 23 and 24, or the shutters 23 and 24 are used. It is possible to more reliably prevent the carrot W from being damaged without causing a difference in the impact force on the carrot W at the contact position.
[0046]
Further, since the fixed partition plate 22 is provided above the upper shutter 23 in the elevating frame 21, the upper portion of the cardboard box 11 (the portion with the top cover raised) and the end side 9 b of the advancing and retracting conveyor 9 by the fixed partition plate 22. The carrot W sent and dropped from the advancing / retreating conveyor 9 can be reliably guided into the respective compartments 25a to 25d. Further, since the lifting frame 21, the various cylinders 18, 27, and 28 and the cardboard box 11 are arranged on the weighing machine 10 via the frame 17, and the weight thereof is measured, the carrot W put into the cardboard box 11 is used. The weight increase due to can be accurately measured.
[0047]
In addition, when the measurement values measured by the weighing machine 10 are set to, for example, eight predetermined values set in advance, the shutters 23 and 24 corresponding to the predetermined values are opened. While being accommodated on each of the shutters 23 and 24, it can be reliably guided downward. Accordingly, it is possible to smoothly move the carrot W from the compartments 25a to 25d to the bottom surface 11a of the cardboard box 11 in each of the compartments 25a to 25d (that is, boxing).
[0048]
Furthermore, since the supply conveyor 2 has a pair of inclined chutes 5a and 5b and V-shaped belt conveyors 7a and 7b, the direction of the carrot W supplied from the keyboard conveyor 4 is aligned in a predetermined direction. It can supply to the belt conveyor 8 with the crosspiece 8a. Further, since the conveying direction C of the pair of V-shaped belt conveyors 7a and 7b is directed to the belt conveyor 8, respectively, the carrots W that are reversed in the respective V-shaped belt conveyors 7a and 7b are alternately arranged. The carrots W on the belt conveyor 8 and the advancing / retreating conveyor 9 can be easily set in a reverse direction by simply sending them to the belt conveyor 8.
[0049]
Further, the advancing and retreating conveyor 9 moves forward and retreats stepwise from the front side (compartment chamber 25a side) to the rear side (compartment chamber 25d side) of the plurality of compartments 25a to 25d, while the carrot W on the advancing and retreating conveyor 9 Is dropped into the compartments 25a to 25d of the cardboard box 11, so that the carrot W can be boxed substantially continuously into the plurality of compartments 25a to 25d. Thus, the boxing operation can be performed mechanically, the manual operation can be rationalized, the boxing operation efficiency can be increased, and the cardboard box 11 can be set by setting the direction of the carrot W in the reverse direction. It becomes possible to increase the boxing rate of the carrot W inside.
[0050]
In addition, the shutters 23 and 24 that once receive a predetermined amount of carrot W are formed in a simple single-opening type (or double-spreading type), and the shutters 23 and 24 that are in a substantially vertical state when opened are a plurality of sections. Since it serves as a partition plate (wall surface) for the chambers 25a to 25d, a vertical partition plate dedicated to each of the compartments 25a to 25d is not required, and the configuration of the elevating frame 21 can be simplified. Further, since the cylinders 18, 27, 28, etc. are used for the raising / lowering operation of the lifting frame 21 and the opening / closing operation of the upper shutter 23 and the lower shutter 24, the operation mechanism can be simplified, and thereby, the packaging device 1 itself can be operated. It becomes possible to simplify the configuration and to form it at low cost.
[0051]
11, 12 and 13 show other embodiments of the boxing device according to the present invention. In the following description, the same parts as those in the above embodiment are denoted by the same reference numerals. First, the embodiment shown in FIG. 11 is characterized in that in the above embodiment, four compartments 25a to 25d are formed by the upper shutter 23 and the lower shutter 24 in a state where the fixed partition plate 22 is opened in the elevating frame 21. On the other hand, the four fixed partition plates 38 are fixed in the vertical state in advance in the elevating frame 21, and the upper shutter 23 and the lower shutter 24 are disposed at predetermined positions above and below the fixed partition plate 38 so as to be opened and closed. .
[0052]
Also in this embodiment, when a predetermined amount of carrot W is supplied onto the closed upper shutter 23, the upper shutter 23 is opened by the operation of the upper shutter opening / closing cylinder 27 and guided to the lower shutter 24. Further, when a predetermined amount of carrot W is supplied onto the lower shutter 24, the lower shutter 24 is opened by the operation of the lower shutter opening / closing cylinder 28, and the carrot W can be packed in the bottom surface 11a of the cardboard box 11, etc. The same effect as the above embodiment can be obtained.
[0053]
12 and 13 is characterized in that a chute 39 branched in two directions is arranged on the end side of the belt conveyor 41 in place of the keyboard conveyor 4 and the chutes 5a and 5b of the supply conveyor 2. At the same time, two belt conveyors 40a and 40b as posture correcting means having an upward inclination on the end side of the chute 39 are connected. According to this embodiment, the belt conveyors 40a and 40b having an uphill inclination are aligned (posture correction) so that the thick end of the carrot W is downward (upstream in the conveying direction h).
