Description

[0001]
[Industrial application fields]
TECHNICAL FIELD The present invention relates to a posture aligning device used for aligning the orientation of flattened fruits and vegetables such as strawberries and tomatoes that are easy to roll, and a boxing device equipped with the device.
[0002]
BACKGROUND OF THE INVENTION AND PRIOR ART
In recent years, boxing of fruits and vegetables performed at a fruit selection plant or the like is usually performed by mechanization and automation. For example, fruits and vegetables accumulated by one or a plurality of hanging rods having a suction plate at the lower end. There is known a system in which a predetermined number is suspended and transferred from a stacking unit into a packing container such as a box.
[0003]
By the way, when adhering and hanging fruit and vegetables such as strawberries and tomatoes with a hanging rod, when the fruits and vegetables are suspended by the adsorption plate at the lower end of the hanging rod, if there is a stickiness on the adsorption surface, reliable suspension is achieved. Since there is a case where it cannot be performed, a process is generally performed in which a surface without sticking is directed to the suction surface (the upper side of the suspended fruits and vegetables). The device used for this process is generally called a fruit and vegetable reversing device, and is used as a pre-processing device in the boxing device to ensure reliable suspension by adsorption hanging when packing fruits and vegetables such as strawberries and tomatoes. It is normal to be attached.
[0004]
As such a reversing device used for boxing processing by reliably adsorbing and suspending fruits and vegetables being transported in a state where the sticker surface is not specified as either upper or lower, for example, Known proposals such as Japanese Utility Model Publication No. 61-125903 and Japanese Utility Model Publication No. 6-3774 are known.
[0005]
Of these, the reversing device described in the former Japanese Utility Model Publication No. 61-125903 is based on the fact that straws, tomatoes, etc. are round and have an unstable shape that is relatively easy to rotate. Is brought into contact with a rotating brush or a hanging rubber curtain to facilitate the rotation by catching when there is a stick on the upper surface, and to perform reversal.
[0006]
Further, the reversing device described in the above Japanese Utility Model Publication No. 6-3774 stretches a linear object such as a wire at a predetermined height on the conveyor conveyance surface perpendicular to the conveyance direction, It is something that is hooked on the body and forced to reverse.
[0007]
[Problems to be solved by the invention]
However, each of the proposed methods has a problem in that it is not always possible to reliably reverse all the target fruits and vegetables in actual work.
[0008]
This problem is particularly noticeable in the part where the fruits and vegetables are transported without gaps. In other words, in the transport state with no gap as described above, the fruit and vegetables in the middle of reversal may hit the subsequent fruit and vegetables, and the reversal may be hindered. This is because a reversal failure is caused. Therefore, this problem can be solved by increasing the interval between fruits and vegetables. However, this inevitably causes another problem that the conveyance efficiency is lowered.
[0009]
In addition, these proposed methods promote the rolling of fruits and vegetables, which are relatively easy to roll, by contact with a rubber screen or a linear body, so that no stickers are located on the upper surface-that is, there is no need for inversion- Even in the case of fruits and vegetables, there is a problem that some fruits and vegetables that do not need to be inverted may be inverted due to their rolling promotion effect even if the probability is small.
[0010]
Any of these reversal failures may cause a suspension error during the packaging operation in the reversal process performed as a pre-process for the packaging device. The postures of the boxed fruits and vegetables are not uniform, which is not preferable when the lid is opened and displayed in a secondary market or a store.
[0011]
The present invention solves the problems of the conventional reversing device as described above, and simultaneously satisfies the two requirements that the necessary fruits and vegetables are reliably reversed and that the fruits and vegetables that do not need to be reversed are not reversed at all. The purpose of the present invention is to provide a posture alignment apparatus for fruit and vegetables with a stick that enables a highly reliable reversal process.
[0012]
Another object of the present invention is to provide a posture aligning device for fruit and vegetables that can be conveyed continuously and efficiently without the need to widen the distance between the conveyed fruits and vegetables while realizing such a highly reliable reversal process. is there.
[0013]
In addition, another object of the present invention is to provide a fruit and vegetable packaging apparatus capable of performing automated and mechanized packaging processing with high productivity by utilizing such reversal processing having high reliability and excellent transport efficiency. Is to provide.
[0014]
[Means for Solving the Problems]

The invention of claim 1 is not particularly limited as long as it is fruit and vegetables that have a sticker and are required to align the position of the sticker to the upper side or the bottom side. By providing a reversing means in the second transport path to which the fruits and vegetables where the fruits are located are arranged, the postures of all the fruits and vegetables are aligned so that the stickers are located on the bottom side, and the boxing process is performed satisfactorily. Therefore, tomatoes, strawberries and the like can be mentioned as typical target fruits and vegetables.
[0016]
The 1st-3rd conveyance path in the structure of the said invention can be comprised using the thing of suitable conveyance systems, such as a belt conveyor and a roller conveyor, and is not specifically limited.
[0017]
The above-mentioned distribution means is, for example, a pusher (air cylinder device or the like) that pushes fruits and vegetables to one side in a direction orthogonal to the transport direction ) However, an appropriate configuration can be adopted.
[0018]
In the above configuration, the means for transferring the fruits and vegetables reversed in the conveying path having the reversing means to any one of the first to third conveying paths is generally a normal belt conveyor although it depends on the structure of the reversing means. It can be formed using a roller conveyor or the like. As a transfer destination, when the reversing means is provided in the second conveying path, the third conveying path, when the reversing means is provided in the third conveying path, the second conveying path, It can be cited as a meeting point for fruits and vegetables with a uniform posture. Moreover, the return method which returns the fruit and vegetables reversed to the 1st conveyance path is also employable. In the return method for returning the fruits and vegetables to the first transport path, it is preferable to have a configuration in which the returning means is returned to the upstream side of the posture determining means when the distributing means is provided.
[0019]
For example, A reversing means for vertically reversing the fruits and vegetables is provided in the second transport path to which the fruits and vegetables with the upper side positioned are distributed, and a plurality of third transport paths having no reversing means are arranged in parallel. The distribution means Fruits and vegetables to be transferred to these multiple conveyance paths The average Configured to distribute equally did . This distribution means is, for example, a combination of a swinging sorting gate and a guide rail as described in Japanese Patent Publication No. 58-39729, and the fruits and vegetables are sequentially placed in a plurality of conveyance paths partitioned by the guide rail. A method of distributing, a method of distributing by a conveying path in which the downstream side oscillates with the upstream side as a fulcrum, and a fruit and vegetable on a fruit and vegetable conveying plate that can move in a direction orthogonal to the conveying direction as described in Japanese Patent Publication No. 5-24008 There is no particular limitation such as a method in which the supply positions to the third conveyance path are distributed one by one, and various known ones can be appropriately employed.
[0020]
The reversing means can be used without being limited to the reversing method and the device structure as long as all fruits and vegetables passing through the reversing means can be reliably reversed. Examples include a turn type belt system.
[0021]

According to this configuration, the fruits and vegetables accumulated in a plurality of rows can be sequentially packed by a plurality of hanging hooks, and an efficient and mechanized efficient packaging process can be realized.
[0025]
[Action]
According to the posture aligning apparatus for fruit and vegetables of the present invention, fruits and vegetables that are transported randomly without the position of the head being fixed up and down are always reversed, and those that do not need to be reversed The posture is aligned by an ideal reversal process that is not reversed at all.
[0026]
Therefore, according to the boxing apparatus having such a posture aligning device, the packaging state is in a preferable packing state in which all the postures of the boxed fruits and vegetables are uniform, and when the transfer means for packing of the suction suspension method is used, There will be no mistakes.
[0027]
In addition to the pre-processing for boxing as described above, the posture alignment processing for fruit and vegetables with stickiness measures the selection elements by a technique such as imaging-image processing, and based on this, appearance quality, internal quality, etc. It can also be used when sorting based on the process is automated. In other words, in the recently proposed image processing for quality judgment etc., it is constant whether the fruit and vegetables such as tomatoes are picked up in a state where they are reflected or are not captured Otherwise, the sorting result is extremely inaccurate and results in meaningless evaluation. Therefore, imaging with a constant posture can be realized by aligning the orientation of the stitches at the stage of imaging with the posture alignment device of the present invention.

[0050]
In this example, a cocoon is taken as an example of the target fruit and vegetable, but the same effect can be obtained even with other fruit and vegetable such as tomato.
[0051]
Example 2
The present example shown in FIGS. 5 and 6 is provided in the middle of the reversal conveyance path 51 to which the basket 100a with the head located on the upper side is distributed by the sorting device 4 of the first embodiment. In this example, the reversing device 71 has a different configuration, and the other configurations are the same as those of the first embodiment. Accordingly, the drawing shows only a part of the boxing device, and common members are denoted by the same reference numerals and description thereof is omitted.
[0052]
The feature of this example is that the end portion of the receiving conveyance path 511 of the reverse conveyance path 51 on which the basket 100a with the top located on the upper side from the sorting device 4 is transferred, and a predetermined position (attitude determination) of the first conveyor 1 The starting end portion of the return conveyance path 512 that is returned to the upstream position of the apparatus 3 is configured to have a certain step in the vertical direction, and the forced reversal type using a belt and a roller described below is used for the step portion. The reversing device 71 is provided.
[0053]
Details of the reversing device 71 are shown in FIG. That is, the reverse conveyance path 51 of this example includes an acceptance conveyance path 511 that receives the basket 100a from the sorting conveyor 4, and a return conveyance path that returns the inverted basket 100b to the upstream of the posture determination device 3 of the first conveyor 1. The reversing device 71 is disposed between the receiving conveyance path 511 and the return conveyance path 512. The reversing device 71 is a semicircular orbit that rotates in a substantially semicircular shape from the state in contact with the upper surface of the ridge 100a on the receiving conveyance path 511 to the state in contact with the bottom surface of the ridge 100b transferred to the return conveyance path 512. Including an endless drive type reversing conveyor 711 and a driven roller 712 opposed to each other with a gap enough to hold a ridge inside the semicircular track of the reversing conveyor 711, and from a receiving conveyance path 511 As shown in FIG. 6, the collar 100a entering the gap between the reversing conveyor 711 and the driven roller 712 is rotated by 180 ° in a semicircular shape, so that the collar 100a with the upper side positioned on the upper side is forced to the posture with the lower side positioned on the lower side. Thus, the bag 100b with the posture located on the bottom side is sent back to the return conveyance path 512 and further returned to the predetermined position of the first conveyor 1.
[0054]
According to the posture aligning apparatus of the present example having the above configuration, it is compulsory while being held by the reversing conveyor 711 and the driven roller 712, as compared with the method of reversing the bag 100a by dropping and rotating at the stepped portion of the first embodiment.

It should be noted that the upstream walls of the partition walls of the lanes 601 and 602 of the packing conveyor 6 and the partition walls of the aligned storage section 8 are omitted as shown in the figure, because the amount of soot to be reversed is not necessarily a constant rate. This is because a part of the storage state of the lane 801 in the aligned storage unit 8 can be shifted to the lane 802 independently. Note that in this case, the sorting device 4 distributes the basket 100b with the bottom located on the bottom side in the lanes 602 to 603 of the boxing conveyor 6, and the lane 602 depends on the ratio of the basket to be reversed. In many cases, it is preferable to reduce the distribution ratio to the other lanes 603 and 604.
[0058]
Example 4
In this example shown in FIG. 8, the configuration for the reversal processing, that is, the receiving conveyance path 521, the reversing device 7, and the return conveyance path 522 are the same as those in the third embodiment, but the heel posture (that is, either 100a or 100b). Shows an example of a configuration in which the distribution method according to the necessity of the reversal processing according to the attitude) and the distribution method from the first conveyor 1 to the aligned storage section 8 having four lanes 801 to 804 are different. . Others are the same as Example 3.

The swaying sorter conveyor 41 whose downstream end is oscillated as an upstream fulcrum is used as the first conveyor 1 so that the basket 100b that is transferred and has the bottom located on the bottom side is transferred to the transfer conveyor 411. It is in the place which is connected to the terminal part of the.
[0060]
In addition, another feature of this example is that a swing-type sorting conveyor 42 is provided, which is connected to the transfer terminal end of the transfer conveyor 411 and swings on the downstream end side as an upstream fulcrum similar to the above. Similarly, the basket 100b transported without being reversed is transferred to the lanes 603 and 604 of the boxing conveyor 6 and connected to the transfer terminal end of the transit conveyor 412 connected to the return transport path 522. A swing type sorting conveyor 43 whose downstream end side is swung as an upstream fulcrum is provided, and the basket 100b reversed by the reversing device 7 is transferred to the lanes 601 and 602 of the boxing conveyor 6. There is. In the illustration of this example, the lanes 601 to 604 of the boxing conveyor 6 are provided so as to be inclined so that the intervals in the width direction are slightly close to each other, according to the intervals of the hanging rods 911 during the boxing operation. This is to obtain an aligned state (integrated state).
[0061]
The posture aligning device of the present example configured as described above is configured so that the posture of the basket supplied on the first conveyor 1 is set upward with the configuration of the sorting processing device and the like provided in the previous stage of the present example device. This is preferably applied to the case where the bottom side and the bottom side are approximately the same level. It is distributed to the lanes 603 and 604 of the boxing conveyor 6 without performing at all. Moreover, the basket 100a supplied to the first conveyor 1 with about half of the looseness located on the bottom side is always subjected to a reversal process and distributed to the lanes 601 and 602 of the boxing conveyor 6. Therefore, the ridges 100b having a fixed posture are distributed substantially evenly to the lanes 801 to 804 of the alignment supply unit, and the advantage that the boxing operation can be performed efficiently is obtained.
