Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bag removal device [l] that removes the bag after cutting off the stalk of a packaged fruit with stalks harvested together with the bag.

For example, when cultivating fruits such as pears and apples, to prevent the fruits from being attacked by pests and disease bacteria, or to prevent them from being exposed to wind, rain, or burning, the growing I+ () is covered with a paper bag, etc. The part is fastened with a metal fitting such as 11-karat gold, and is fixed and supported at the stem part.

When harvesting fruit, the fruit is separated from the fruit tree in its bag as a packaged fruit with stalks, and then the stalk part of the packaged fruit with stalks is cut off again using the stalk cutting and bag removing device, and the bag of the packaged fruit part is removed. It is being removed.

Conventionally, this type of bag removal device has been used, for example, to place a packaged fruit (=1 fruit) on a fruit conveying device with the fruit stem facing downward, and to remove the fruit stem from a conveyor equipped with a ditock disposed below the fruit conveying device. Grasp the fruit stalk and move the bag while pulling it downwards, cut off the fruit stem with a cutter rotating between the fruit conveyor and the J conveyor, and then apply pressure air from the blowing device to the packaged fruit to bag it. The bag is lifted up from the fruit, the bag is held by a bag removal device disposed above the fruit 1117 j'!= device, and the bag is moved upward while being squeezed up to remove the bag.

However, in conventional bag removing devices, the clamping body is made of a rigid body or a metal bullet, which may cause damage to the fruit when clamping and squeezing the bag, or may cause damage to the bag. There is a problem in that bag removal becomes unreliable if the fruit is too large or the bag is wet. In addition, there is another problem in that the clamping body, which cannot be fully opened due to malfunction or the like, collides with other members, such as the blower nozzle that sends air to lift the bag, during the transfer, and damages them.

The present invention was devised in view of the above problems, and its purpose is to provide a bag removal device that can prevent damage to fruits and other objects, and can also effectively remove bags. There is a particular thing.

In order to achieve the above object, the present invention provides a bag removing device having a clamping body 9 that squeezes and clamps the packaging covering the fruit to be transported from both sides of the fruit while transferring the fruit. In this case, the clamping body 9 is composed of a relatively hard elastic body 10 and a relatively soft elastic material 11 covering the elastic body 10.

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

/El is a fruit pressing device, which is arranged above the fruit conveying device 3, and holds the packaged fruit 1 with stalks placed on the placing part 16 of the fruit conveying device 3 from above II [1 pressing (J Shino (Yes, it is structured as follows. /15 is 1
The fruit conveying device 3 is loaded with an endless section 1 of the row.
1111 is placed above the machine frame 14 and can rotate freely once in the machine frame 14.
It is suspended from the front and rear sprockets 46 supported by 11. The endless chain 45 is configured to rotate in the same direction at the same speed as the fruit conveying device 3. The presser cup 47 located at -C is attached.

It is a prime mover that rotationally drives the conveyor 18 and the bag removal device 8 via a transmission mechanism (not shown).

Next, the operation of the above embodiment will be explained.

The rotating parts are driven by the prime movers 23 and 48, and the packaged fruit is placed on the mounting part 16 of the fruit conveying device 3 by inserting the fruit 1, the fruit 2, with the fruit 2 facing down, into the 4-hole 17. The stalked fruit 1 is moved with the stalk part 2 brought out below the placing part 16. When the chuck (=J conveyor 18) comes above, the chuck 2'1, which moves in the same direction at the same speed as the fruit conveying device 3, is forcibly opened by the guide rail 22 and grabs the fruit stem 2. , move while pulling downward J

When reaching the end of the stem 8, the cutter 4 cuts off each part of the stem 2 into a bag.

Next, the packaged fruit 5゜6 with the stem part 2 cut off moves while riding on the placing part 16 of the fruit conveying device 3, and when it reaches the upper part of the CC Kawakaze device, it is removed from the blower device 7. Pressure wind is through hole 1

lifted up from. Then, the clamping body 9 of the bag removing device 'It'i 8, which moves in the same direction at the same speed as the fruit conveying device 3, is forcibly opened by the guide rail 40 at a position above the blower device 7. When the clamping body 9 closes, the bag 6 clamps the floating packaged fruits 5, 6 from the left and right sides, and moves while squeezing the bag 6. Then, the bag 6 is removed from the fruit 5 at the end of the operation of the bag removal device 8, and q! The fruit 5 is taken out of the machine from the terminal end of the fruit conveying device 3, and the bag 6 is transferred while being held by the holding body 9. The clamping body 9 that clamps the bag 6 is forcibly moved by a guide rail 41 installed at an upper position on the action end side.
The bag 6 that has been pinched is blown away by a single wind from the blower 42 and is discharged from the first output tube 43 to the outside of the machine.

FIGS. 7 to 10 show the second embodiment, in which the front and rear clamping bodies 9 are connected by a stretchable soft elastic member 49. By connecting the front and rear clamping bodies 9 with this soft elastic member 49, the squeezing action can be strengthened, thereby improving the bag removal effect.

Note that in FIGS. 7 to 10, the same reference numerals as in FIGS. 3 to 6 indicate the same components.

As is clear from the above explanation, according to the fourth aspect of the present invention, since the clamping body is composed of an elastic body and an elastic material coated thereon, the clamping body cannot fully open due to malfunction etc. When the gripping body is in the middle of moving, it may collide with other members, such as the feeding nozzle that sends air to lift the bag from the fruit. 9. The elastic material bends to prevent damage due to collision. When the bag is squeezed up, since the material that comes into contact with the fruit is a relatively soft elastic material, damage to the fruit can be reduced, and the bag can be squeezed out more easily. Sagging due to elastic deformation of the clamping body is extremely small because the relatively hard elastic body acts as a core.

Note that this invention is not limited to the above-mentioned embodiments, and the invention can be implemented in modes other than the above-mentioned embodiments.
