Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention involves loading a predetermined amount of long, slender, rod-shaped products to be packaged, such as dried noodles, into an automatic packaging machine or the like.
This invention relates to a device that transfers the rear end surfaces at predetermined pitches while aligning the rear end surfaces flush. ≪Prior Art≫ In an automatic packaging machine that continuously performs packaging using a strip-shaped film, when a predetermined amount of long, slender rod-shaped items to be packaged, such as dried noodles, are transferred to the automatic packaging machine in one batch, If the front and rear edges of the packaged items are not aligned flush before being sent to the automatic packaging machine, troubles such as jamming of the packaged items in the top seal/cut device of the automatic packaging machine may occur. However, it had the disadvantage that it could not be packaged securely. Therefore, in order to eliminate the above-mentioned drawbacks,
The applicant has already developed a method such as that disclosed in Japanese Patent Application No. <<Problems to be Solved by the Invention>> However, what is disclosed in the above-mentioned publication is that an opening/closing plate with a balance weight is provided with an upper rotating shaft rotatably attached to the top of the tip of the article transfer gutter, and the opening/closing plate is After pressing the leading end of the packaged object being pushed by the article pushing plate and aligning the front and rear ends of the packaged object flush with the resistance of the opening/closing plate, the opening plate is rotated. The pusher is rotated upward by the operation of the pusher to remove the blocking force of the opening/closing plate against the packaged item, and then the packaged item is fed into the automatic packaging machine. Therefore, it is mechanically very difficult to adjust the timing to open the opening/closing plate when the end faces of the packaged items are properly aligned, and as a result, it is difficult to adjust the timing to open the opening/closing plate when the end faces of the packaged items are properly aligned. I couldn't do it. That is, if the opening timing of the opening/closing plate is delayed, there is a risk that the front and rear end surfaces of the packaged object may be broken due to the pressing force between the opening/closing plate and the article pushing plate, and the opening timing of the opening/closing plate may be delayed. When the speed is increased, there is a drawback that alignment of the leading and trailing ends of the article to be packaged is insufficient. There is also an alignment conveyance device disclosed in, for example, Japanese Utility Model Publication No. 45-31209. In this device, articles are placed at a predetermined position above a conveyor with a pushing finger that conveys articles at a constant speed (at a lower speed than this conveyor). In this method, an article front restraining plate that moves at a constant speed is arranged, and by adjusting the ratio of both speeds, the articles are aligned by being held between the article front restraining plate and the pushing finger. However, in this device, since the pushing finger and the article front holding plate move at a constant speed,
Adjusting the speed ratio between the two becomes extremely difficult.
If the adjustment is incorrect, problems similar to those described above will occur. Furthermore, it cannot be applied to cases where the lengths of articles are different, resulting in poor versatility. This invention was made in view of the above-mentioned problems, and its purpose is to feed a predetermined amount of easy-to-break, elongated rod-shaped items to be packaged into an automatic packaging machine, etc. at predetermined pitches. When carrying out packaging, it is possible to ensure alignment of the leading and trailing ends without breaking the packaged item, and also to accurately feed the packaged item at predetermined pitches into an automatic packaging machine, etc. without destroying the alignment. An object of the present invention is to provide a device for aligning and transferring packaged items. <<Means for Solving the Problems>> In order to achieve the above-mentioned object, the packaged object alignment and transfer device according to the present invention has a front surface of the packaged objects in the packaged object transfer gutter and an article pushing plate in front of the packaged object transfer gutter. disposing an article front restraining plate that enters at a predetermined position between them, and bringing the article front restraining plate into contact with the front surface of the packaged object by sequentially slowing down the transport speed of the article front restraining plate than the transport speed of the article pushing plate; A mechanism is provided for shifting to a constant velocity when the distance between the article front holding plate and the rear article pushing plate becomes approximately equal to the length of the article to be packaged, and then moving the article away from the article transfer gutter at high speed. . <<Operation>> The article front holding plate enters a predetermined position between the front surface of the packaged article in the packaged article transfer gutter and the article pushing plate in front of it. Since the speed of the article front restraining plate at this time is slower than that of the article pushing plate located at the rear, the distance between the two gradually decreases, and the article front restraining plate comes into contact with the front surface of the article to be packaged. Thereafter, as the distance between the two is further reduced, the front and rear ends of the packaged object are held, and the protruding parts at the front and rear ends are pressed forward and backward, respectively, so that the front and rear ends of the packaged object are pressed. Align the end faces flush. Next, when the distance between the article pushing plate and the article front restraining plate substantially matches the length of the article to be packaged, the velocity becomes constant, and during this constant velocity transition, the alignment state is maintained. Thereafter, the speed of the article front restraining plate becomes higher than the moving speed of the article pushing plate, that is, the moving speed of the object to be packaged, and the article front restraining plate is smoothly separated from the front surface of the object to be packaged. By doing this, it is possible to reliably align the object to be packaged, and furthermore, the adjustment in this device is performed when the distance between the article pushing plate and the article front holding plate approximately matches the length of the object to be packaged. It is sufficient to maintain the same speed (there is no need to adjust the separation timing, etc.), and the adjustment work is easy. <<Embodiment>> FIGS. 1 to 9 show a first embodiment of the present invention.

A front article restraining plate is provided that moves the article to be packaged in the transfer gutter at slow, constant, and high speeds, and when the article front restraining plate moves at a slow speed, the article is moved by utilizing the difference in speed between the article and the article pushing plate. While conveying at a constant speed, the front and rear ends of the packaged object are held between the front and rear sides by the article pushing plate and the article front restraining plate to continuously transfer the protruding portions of the front and rear ends of the packaged object, respectively. While pressing in the front and rear directions, the front and rear end surfaces of the packaged items are aligned flush with each other, and during constant speed transfer, the above-mentioned aligned state is maintained while transferring, and furthermore, the above-mentioned article front presser plate is pressed during high speed transfer. By quickly separating from the front surface of the object to be packaged, the end faces of the object to be packaged can be easily and reliably and sufficiently aligned in a stable state. Furthermore, it has the advantage of being able to accurately feed each predetermined pitch into an automatic packaging machine without disrupting the alignment state.
