DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention discriminates the posture of chopsticks in a machine for automatically attaching chopsticks to the side of a lunch box.

[0002]

2. Description of the Related Art Conventionally, in a lunch box manufacturing plant, chopsticks were manually attached to the side of a lunch box container. Recently, a machine that pastes the work directly into a lunch box using a hot gluer has begun to come out, but another good thing is the rise time of the gluer, temperature control, contamination of the machine and its surroundings, defective rate, etc. Was desired.

[0003]

The ideal conditions for sticking to the side of a lunch box container are that the chopstick packaging material is made of paper and is aesthetically pleasing.
I want to keep the top and bottom, and the front and back, and want to include a toothpick with chopsticks after pasting to remove the same printing on both sides, but do not damage the sticking condition of the container for the toothpick .

In view of the above technical problems, the present invention selectively supplies ordinary chopsticks which are currently diverted, instead of specially wrapped chopsticks which are convenient for machines, so that they can be stably stuck on a lunch box. In addition, we want to reduce the preparation time required for starting and stopping the machine, as the chopsticks can be easily replenished as they are consumed, without damaging the product work. Chopsticks are almost always wrapped in paper, and the chopsticks and the wrapping material are hard and soft and easy to break, but they are incompatible properties. It is in.

[0005]

An object of the present invention is to provide a method of sorting packing chopsticks, wherein the packing chopsticks are separated and arranged from those randomly arranged in a stock hopper (capable of storing 1,000 sets), and one set per lunch box. In this case, it is necessary to select the top and bottom because the inside of the packaging chopsticks is not aesthetically pleasing when the actual chopsticks are in the protruding portion of the lunch box container lid.

[0006]

In order to automatically and unattended the work of putting chopsticks on a lunch box, it is necessary to refill chopsticks automatically or to increase the storage capacity.
However, as described above, in order to maintain the aesthetic value, the packaged disposable chopsticks must be sent out or taken in orderly. A method was proposed in which it was lifted from the inside of the hopper while being temporarily adhered to the body.

In another alternative, the hopper is placed in the upper position, the hopper outlet shooter bottom plate is vibrated and dropped on a conveyor located below the minority outlet shooter bottom plate. When the packaging chopsticks on the conveyor are consumed, they are detected by the photoelectric switch, and the outlet shooter bottom plate is re-vibrated to replenish it.

According to a sixth aspect of the present invention, there is provided a method for separating packaged chopsticks from top to bottom, in order to attain the intended purpose, the suction cup to be pressed into a shape approximate to either the left or right of the solid chopstick. The packaging chopsticks to be used are characterized by top and bottom sorting.

According to a seventh aspect of the present invention, there is provided a method for sorting packing chopsticks vertically, wherein a bottom plate for supporting the packing chopsticks at a predetermined position is tiltable so as to achieve the intended purpose. The bottom plate is tilted left or right according to the left and right of the solid chopsticks, and the top and bottom of the chopsticks is selected by electrically and mechanically responding to the change in the movement of the bottom plate.

In order to achieve the intended purpose, the method for separating packaged chopsticks according to the present invention is characterized in that the suction cup is swingable and the change of the suction cup swing is electrically and mechanically sensed. It is characterized in that the packaging chopsticks to be made are sorted vertically.

[0011]

According to one embodiment of the present invention, the chopsticks which have been packaged are also pulled up from the chopstick stock by the vacuum suction ports provided at regular intervals in the conveying strip. Therefore, the mechanical timing can be accurately measured. Only if a specific portion of the packaged chopsticks is located in the vacuum suction port, it becomes easier to mechanically determine, so that the chopsticks are aligned. Automation of vacuum pressure adjustment and
The use of special phototubes has a posture discrimination function and a shape property discrimination function that skillfully utilizes the characteristics of chopsticks packaged.

According to another embodiment of the present invention, the packing chopsticks flowing from the previous step (hopper) are aligned and separated, and the packing chopsticks are put into the landing one by one, and are lifted by the sucker from the packing chopsticks. The top and bottom can be discriminated and classified within the instantaneous time until moving to the next step.

This means that by setting the driving speed of the transport band to be greater than the consumption speed of the chopsticks, the suction port pitch E provided in the transport band does not necessarily have to have chopsticks.

The scraping roll 5 is provided with an interval corresponding to the thickness of the transporting band 2 and the thickness of the chopsticks, so that when the thickness of the chopsticks exceeds a predetermined amount, the scraping roll 5 cannot pass.

The scraping roll 5 rotates in a direction opposite to the direction of travel of the transport band 2, controls the number of rotations by friction with the surface of the disposable chopstick packaging material, and controls the suction port provided in the transport band. Prevention of the progress of chopsticks packaged by mutual balance based on suction pressure, suction area and suction adhesion, and
The chopsticks can be flipped in the opposite direction.

The scraping roll 5 is provided with a scraping plate 6 which rotates in synchronism with the suction port 13 provided in the transport strip 2, so that when the object to be transported is located at a position other than the suction port 13 and the predetermined position, the transport strip is formed. It can also be flipped in a direction opposite to the traveling direction of the body 2.

When an object to be transported passes through a predetermined position, a detector PH3 for detecting the packaged chopstick itself.
And a position where at least one set of chopsticks packaged by at least two detectors of the detector PH2 for detecting only the wrapping material wrapped (no chopsticks are included) can be detected within a predetermined time range. By reading the right or wrong in the traveling direction of the conveyed object by installing the reverse rotation roller 7 arranged at a predetermined distance from the conveyance belt-shaped body, or by changing the distance, or scraping plate 6,
The protruding pusher 8 can also be used to pass or contaminate the conveyed object and to sort it.

The shape of the sucker 11 is formed so as to match the position and shape of one set of packed chopsticks at a predetermined position. If the packaging is not good, the vacuum degree cannot be maintained and the suction chuck can not be chucked, and if the transfer is impossible, the fixed position stop plate 10 is released and the overflow can be excluded.
