JPS606184A - Apparatus for cutting fruit stem and removing bag from covered fruit - Google Patents

Abstract

PURPOSE:To improve the yield of bag removal from covered fruits, by holding a fruit bag at the part binding the fruit stem in a manner to flatten and collapse the bag, cutting the bag, and tearing the remaining bag to the equator of the fruit. CONSTITUTION:The fruit bag is held at the part binding the fruit stem in a manner to flatten and collapse the bag, and the bound part is cut to the extent to cut the stem but leave a part of the bag without cutting. The remaining part of the bag is utilized to tear the bag to the part of largest diameter, i.e. equatorial part of the fruit. Even a large fruit grown tightly in the bag can be released easily from the bag because the bag is torn and loosened.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that fully automatically cuts the stem and removes the paper bag in the pre-process of sorting fruits such as 20th century pears and apples grown with paper bags over them.

Conventionally, as a device for removing the fruit and the wrapping (paper bag) from a packaged fruit in which a paper bag is wrapped around the fruit and the bag opening is tied at the stem part,
Special Publication No. 50-580, and Special Publication No. 52-27052
The HEI system shown in the publication is mainly used and has been used after repeated improvements, but the purpose of cutting off the binding part between the fruit stem and the package is to remove the package even though it has been formed. This method had the disadvantage that only a bag removal rate of 10% could be obtained, and the remaining 70 bags had to be removed manually.

In addition, Special Publication No. 55-9187, Special Publication No. 9188, Special Publication No. 55-25831, Special Publication No. 55-25832.
No., Special Publication No. 5-25833, and Utility Model Publication No. 57
- The one in Publication No. 56498 has been proposed, but there are few examples of it, and bag removal devices with high bag removal rates +t and u have not been developed, and bag removal is done manually by assigning a large number of people to the bag removal work. The current situation is that

In all of these known bag removal methods and devices, after cutting off the binding part between the fruit stem and the bag, air is blown into the cut opening, the bag is sucked with air, or the bag is grasped. This method involves removing the fruit from the fruit.

However, with these methods, the fruit is small in size and there is room for the bag, and while it is easy to remove the bag, the disadvantage is that the fruit fills the inside of the bag and cannot be removed. was there.

In general, if the paper bag is too large for the diameter of the fruit, it will be 11ω2.
Paper bags are made to be full and not too large for the size of the fruit, as the damage causes bag scratches on the surface of the fruit.

Therefore, the average size of the fruit and the larger ones (for example, LL, 3L, etc.) are in a state where the equatorial part of the fruit is stretched out as if it is being pushed out from inside the loan. The above-mentioned known technical means had the disadvantage that it was not possible to increase the bag removal rate.

The present invention is an apparatus for eliminating these drawbacks and improving the bag removal rate, and its operating method is summarized as follows.

(b) The center of the bundle in the stem of the packaged fruit (axis or stem)
Make a cut that exceeds the size, but do not cut it off, and cut off the stem.
The paper bag should be cut so that about 100cm or more of it is cut and the remaining part is left uncut. (Refer to Figure 2 (A) → 0p) (Refer to Figure 2 (A) → 0p) )→←
) e9 Grasp the paper bag (packaging) that has been torn open to the equator and remove it from the fruit. (See Figure 2 (-U → (・)) As mentioned above, after cutting the package (paper bag) of the packaged fruit at the binding part, tear it to the equator of the fruit and open it wide. The bag can be easily removed by releasing the bag.

In the above operating method, (in step (a), the fruit stem is cut, and in step (b), the cut bundle is pulled in the equator direction of the packaged fruit while keeping the posture of the packaged fruit as it is;
In some cases, the cut bundle is grasped and held as it is, and the packaged fruit is torn up to the equator by rotating the packaged fruit in a horizontal direction. The bag can be removed from the fruit by picking it up, or the bag can be removed by blowing air into the incision, and it is also possible to remove the bag by using both methods in combination.

To explain in more detail, the supply conveyor that places the packaged fruit with the fruit bundles aligned in a certain direction is the first conveyor that has its own mechanism that moves the supplied packaged fruit while holding it in a certain posture. use Next, the second means is a mechanism that grasps and pulls the bundled part of the package during conveyance on the first conveyor, and this second means is incorporated into the packaged fruit holding part of the first conveyor, and as it progresses, it is installed with a cam, rail, etc. In some cases, a device that acts as if to pull the gripped portion is used, and in other cases, a device that rotates in synchronization with the first conveyor, grips the binding portion, and uses a cam, rail, etc. to act as if to pull as it moves forward. This binding portion gripping mechanism preferably uses a gripping method in which the binding portion is gripped from the front and rear directions, rather than a gripping method in which the binding portion is gripped from left and right in the direction of travel, or from above and below. In other words, the dK wrapping part to be cut in the center of the fruit stem is not completely cut off, and the wrapping part is not completely cut off. Some parts can be cut off and left behind.

A cutting knife is placed between the bundle gripped and pulled by the second means and the packaged fruit to an extent that extends beyond the center of the gripping width (centered on the fruit stem) (to cut into the fruit stem), A third means is a cutting device in which one part 7r and B of the package are cut and the gold film is removed.

Parallel to the ray ♀ which grabs and pulls the p binding part metal and then cuts it using the second means, the packaged fruit on the first conveyor is grabbed and held on the fruit gripping machine, and the fruit is moved synchronously and further transported to the destination. In the middle of the transfer process by the conveyor of the fourth means, that is, after passing through the cutting process of the third means, the packaged fruit is caught by the conveyor of the fourth + stage and the bundle part which is caught by the second means and partially torn. and a fifth means of a mechanism that acts to pull the packaging in the equator direction of the fruit,
After tearing the bundle i≦IS at the equator 1 so that all the fruits in the package can be easily removed, the second means returns and the first conveyor also returns. A conveyor is provided ahead of the first conveyor to convey the fruit to the sorting machine for the first step.

On the other hand, the conveyor of the fourth means, which grasps and holds the torn packaged fruit and moves forward, reaches the conveyor, further extends and translates, and is about to return, that is, when it reaches the conveyor ±, it conveys the packaged fruit. After lowering it to the top of the conveyor, I temporarily loosen the gripping mechanism and change the gripping position to a position that allows the fruit to slide off, pick up only the packaging, leave the fruit on the conveyor, and wrap it! A sixth means is provided for separating the fruit from the fruit, and the conveyor of the fourth means, which grips the packaging picked and peeled off from the fruit, returns after passing through the crumbling means. The sixth means is
The fourth means is a gripping mechanism provided on the conveyor, which is composed of a cam, a rail, etc. that opens and closes and moves up and down. Wrapping using air at the top
Sometimes it can be taken off. The package $J removed by the former method is discharged from the apparatus by releasing the gripping mechanism as part of the return process.

On the other hand, the naked fruits are placed on a conveyor and are conveyed as they are to the sorter by the conveyor.

As described above, the present invention cuts the packaged part of the packaged fruit to the peduncle, but leaves a part of the package and uses the uncut part to tear the packaged fruit to the maximum diameter part, that is, to the equator part. Since the packaging is opened with a loud sound, even if a large fruit is stuck inside the packaging, the packaging is torn and loosened, so the packaging can be separated from the fruit very easily and the bag can be removed with high efficiency.

In addition, the present invention provides that, after all packaged fruit is supplied to the first conveyor at the start, the fruit is transferred from outside the package while being hung until it is placed on the conveyor to the sorting machine in the final process, and the fruit is transferred from the outside of the package. Cutting, tearing, and bag removal are performed during the process, and the fruit is not transferred even once. This eliminates damage such as scratches, bruises, etc. that previously occurred when all the fruit was transferred between processes. It has the effect of not reducing the product value.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 3 is a flowchart using the apparatus of the present invention, and the fourth south section shows the cylinder making process.

1 is a first conveyor, which is a pedestal binding basket 52a for packaged fruits 2;
It has a receiving part 3 on which the objects are placed in a fixed direction and runs horizontally. This first conveyor may be a conveyor similar to a conventionally known conveyor.

Reference numeral 4 denotes a second means of a mechanism for firmly pulling the fruit bundle 2ai of the packaged fruit 2 conveyed by the first conveyor 1, and it rotates in synchronization with the first conveyor 1.

The second means 4 includes a gripping mechanism 5 mounted at the same interval as the receiving part 3 of the first conveyor 1, and the gripping mechanism 5 of the reed is moved close to, stuck to, and separated from the receiving part 3 by means of a guide rail 6. The piece 7 opens and closes on the cam rail 8. As shown in FIGS. 5 and 6, this gripping piece 7ti is formed so as to be gripped flatly in a direction perpendicular to the traveling direction (arrow) of the conveyor, and this point is different from the conventional method. different from that of In other words, a portion of the packaging at the binding portion is left uncut. The gripping mechanism 5 grips the stem binding part 2a and then pulls the core part to a certain distance.

Reference numeral 9 denotes a cutting device as a third means, and a rotary cutter similar to a conventional one may be used, or another chain type cutting mechanism or the like may be used.

10 is a fourth means for grasping and holding the packaged fruit 2 placed in a fixed direction on the receiving portion 3 of the first conveyor 1;
It has a mechanism for lifting, transporting, and lowering it onto two transport conveyors, and runs and rotates in synchronization with the first conveyor 1.

The fourth means 10 has a fruit gripping mechanism 11 installed at the same interval as the receiving part 3 of the first conveyor J, and this fruit gripping mechanism 11 can be moved close to the receiving part 3 by a guide rail 12 or 1i.
i(I got it.

The fruit gripping mechanism J] has fingers 13 for gripping the packaged fruit 2 softly and firmly, and the fingers 13 are opened and closed by an opening/closing cam rail 14 and held by a spring 15. The fruit grasping mechanism 11 is connected to the second means 4.
The packaged fruit 2 is grasped at approximately the same time as the grasping machine tPt5 of the fruit stem binding part 2a is activated, and the binding part is pulled and the cutting device f'
Hold in a fixed position until cut with J9.

After passing through the cutting device 9 of the third means, the gripping mechanism 5 (l-1: g-id rail 6) of the second means approaches the receiving part 3 again, loosens the tension on the binding part, and moves forward while holding the binding part. At the same time, the fruit grasping mechanism 11 of the fourth means moves forward by slightly lifting the fruit from the receiving part through the idle rail 12.

A fifth means 16 is provided in this advancing step.

The fifth means 16id is configured in conjunction with the fruit grasping mechanism 11 of the fourth means 10, and in this embodiment, the fifth means 16id is the fifth means 16id.
As shown in Figures 9 and 10, the gripped packaged fruit 2 is tilted sideways in a swinging manner to remove the cut residue, and the package is torn in the equator direction of the fruit from the package binding part, and then the package is torn in the equator direction. It is operated by a cam rail 17. That is, the fruit grasping mechanism 11 is built into the holder 18 of the conveyor of the fourth means 10 in a sliding manner so that it can slide when approaching the first conveyor 1 or away from the first conveyor 1, and has a finger 13 and an opening/closing rod 19 at its core. A mechanism that swings and tilts the head, and a tilting movement of 20 t, 1↓ constitutes a fruit grasping machine); dll. Therefore, when this motion is guided by the cam rail 17 for full swing of the rod 20, the fingers 13 that gripped the packaged fruit are tilted as shown in FIG. The force causes the package to tear to the equator of the fruit.

When the tearing process is completed, the fingers 13 return to their original positions, and at the same time, the gripping mechanism 5 of the second means 4 releases the binding portion and returns to the starting side. On the other hand, the fruit gripping mechanism 11 of the fourth means 10 gradually moves away from the receiving part 3 by the guide rail 12 while gripping the packaged fruit, and advances with the torn bundle hanging down. When the fruit is lifted from the receiving part 3, the first conveyor 1 comes to the end and returns to the starting side.

A conveyor 21 is provided at the end of the first conveyor 1 to convey the fruit to a sorting machine for the next process. The fruit grasping mechanism 11 of the fourth means for lifting and transferring the packaged fruit approaches the starting end of the conveyor 21 so that the packaged fruit gripped by the fingers 13 is lowered onto the conveyor 21 by the guide rail 12, and then
The fingers '13 of the opening/closing rod 19 of the fruit gripping mechanism 11 are temporarily opened by the cam rail 22 of the sixth means, the grip is loosened, and the fruit gripping mechanism 11 is slightly shifted in the direction away from the conveyor 21 by the guide rail. That is, the tip of the finger 13 is placed shallower than the equator of the fruit, and the fruit is grasped so that it is partially detached from the finger 13; Fin 1f with changed grip position
-13 is closed again, and the idle rail 12 causes the fruit grasping mechanism 11 to proceed one step from the Ia conveyor 2 to the I1.

Therefore, although the tips of the fingers 13 are grasping a part of the spherical surface of the torn packaged fruit, they are grasping shallowly from the equator, so the fruit is not lifted up and instead slides down from the torn part of the package onto the conveyor 21. Only the packaging with the fruit Vcia on top is picked up by the fingers 13, and the packaging is peeled off from the fruit and the fruit is removed.

Peel the packaging from the fruit and get J-1! V-shaped fruit grasping mechanism 11
grabs only the empty package and returns to the starting side, but as part of the return process, the fin force 13 opens and releases the empty package it was holding. This is released! Packaging is air JWi 3. It is carried out of the apparatus by means such as ``f, i9 to -jγ or t to baking 7.:j furnace.

On the other hand, peel off the packaging, /ko (9th conveyor 21)
The divine fruit above (looks down at the next stage of fruition).

For the sixth method, packaging stripper 4+j1, air is supplied once a month.
In some cases, the packaging may be removed.

In the fifth means of unwrapping and transporting, the wrapped fruit is tied ↑6B
The torn pieces of the binding part are torn to the equator and further torn by the second means of gripping machine 11? As part of the return process in step 5, the grasper may be released in 5 clutches (, 7).

In this embodiment, the inside of the first means (lower B10 is provided with the second means, ε1\1 means is placed between the VCC12 means, and the first means 4 is placed; ![-Although a device is shown in which the devices are extended and arranged in series to feed the stem-tied portion of the packaged fruit downward, in addition to this, +1' of each device is formed and the arrangement tJ- f: Alternatively, the device may be configured to feed the packaged fruit with the stem-tied portion facing upward or sideways.

The present invention involves gripping the fruit stem bundle of the above-mentioned through-packed fruit so as to crush it flat, cutting the fruit stem to the extent that the fruit stem is cut and leaving the paper bag uncut, and using the remaining 7911 minutes to cut the fruit into a fruit. Since the package is torn open at the maximum diameter of the fruit's equator, even if the fruit grows inside the package and becomes taut, the package can be peeled off very easily, making it easier to work with reusable bags. It is possible to automate the process and reduce the number of workers, which has a large economic effect.

In addition, when using the apparatus of the present invention, it is difficult to wrap the fruit.
/ j9 Always grasp the fruit from outside the package until it is taken out, without touching the fruit directly, and without rolling the fruit during transfer in each process [H], so it is possible to transfer the fruit without touching it directly. It does not cause scratches or transfer bruises, maintains the original value of the fruit, and has the effect of gaining high praise in the market.
