Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for attaching a cutting blade to a carton in which a band-shaped material is cut into saw blades at predetermined intervals to form a linear cutting blade and the cutting blade is attached to the carton. The present invention relates to a defective carton discharging device that discharges a defective carton with a cutting blade attached incorrectly from a manufacturing line.

[0002]

2. Description of the Related Art Conventionally, there are various types of devices for attaching a cutting blade to a carton, and in recent years, there are cutting blades other than metal, such as paper, synthetic resin, etc. The thing which can be incinerated has also appeared.

The cutting blade is formed by rolling a long strip-shaped material into a roll, feeding the strip into a die set and cutting it to a predetermined length to form a cutting blade. It is attached to a predetermined position of the carton transferred to the set place.

[0004]

In attaching the cutting blade to the carton, the cutting blade must be accurately attached to a predetermined position of the carton. It may not be stuck in the correct position, and a carton may be manufactured with the cutting blade attached in an incorrect position.

However, if a carton having the above-mentioned cutting blade attached at an inappropriate position is put on the market if it is moved along the production line, the defective carton is eliminated from the production line. I have to
If the production line is stopped to remove this defective carton, the production efficiency will be significantly reduced.

[0006]

Therefore, as a result of earnest studies by the inventor to solve the above problems, the present invention arranges the upper guide rod and the lower guide rod up and down, and the upper guide rod At the lower part, a guide part whose upper side is flat,
A movable guide consisting of a discharge guide portion whose lower side is inclined is provided, the guide portion is always on the substantially same plane as the lower guide rod, and the tip end portion of the movable guide is appropriately moved in the vertical direction. By using a defective carton discharge device,
The structure of the entire apparatus can be simplified and defective cartons can be efficiently eliminated, and the above problems are solved.

An upper delivery roller R1 and a lower delivery roller R2 are provided at the tip of the upper guide rod 6 in the vertical direction, and the upper delivery roller R1 and the lower delivery roller R2 rotate to cause the upper guide rod 6 to rotate. The carton a is fed between the lower guide rod 7 and the lower guide rod 7.

As shown in FIG. 2, the upper guide rods 6 are arranged in parallel at predetermined intervals, and similarly, the lower guide rods 7 are also arranged in parallel at predetermined intervals, and further, FIG. As shown in FIG. 4, the upper guide rod 6 and the lower guide rod 7 are arranged at an interval such that the carton a can slide in the vertical direction.

In front of the discharging device A, as shown in FIGS. 2 and 5, an upper feeding roller R1 and a lower feeding roller R2 are vertically arranged, and a carton a to which a cutting blade d is attached is attached. The upper delivery roller R1 and the lower delivery roller R
It is vigorously discharged between the upper guide rod 6 and the lower guide rod 7 due to 2.

The carton a, which is vigorously discharged by the upper delivery roller R1 and the lower delivery roller R2, passes between the upper guide rod 6 and the lower guide rod 7, and the movable guide A1.
When the carton a, which has been properly manufactured and has been transferred, is transferred to the movable guide A1 as shown in FIGS. The heights of the guide portion 1a and the lower guide rod 7 are substantially equal to each other, and the carton a flows over the guide portion 1a of the movable guide A1 and moves to the subsequent process.

Next, when the improperly formed carton a is vigorously discharged by the upper feeding roller R1 and the lower feeding roller R2, this is sensed, and FIGS.
As shown in FIG. 4, the tip of the movable guide A1 is raised by the driving body 3, the discharge guide portion 1b is positioned higher than the lower guide rod 7, and the improperly formed carton a is discharged to the discharge guide portion 1b of the movable guide A1. Along the outside of the production line.

The carton feeding section B, as shown in FIG.
The carton a is sent out in the die die set C direction, and as shown in FIG. 10, an adhesive application device 9 is attached to a predetermined part of the carton sending part B, and a cutting blade d is attached to the carton a. Adhesive attachment for wearing is performed.

A cutting blade mounting body C is provided subsequent to the carton feeding section B. In the cutting blade mounting body C, as shown in FIG.
As shown in FIG. 12, it comprises a mold die set C1 and a mold die set transfer section C2 for transferring the carton a to the position of the mold die set C1.

First, as shown in FIG. 10, the carton feeding section B is provided with two carton feeding driving sections 8 for feeding the carton a to the die set C1 of the die, specifically, a chain. , A belt or other endless flexible body 8a and a transmission wheel 8b such as a sprocket or a belt wheel. The carton a is placed on the carton feed drive unit 8 and is transferred by the rotational movement of the endless flexible body 8a. , The die set D1 is transferred in the direction of C1.

At an appropriate place of the carton feeding section B,
As shown in FIG. 10, an adhesive agent applying device 9 is mounted, and the adhesive agent applying device 9 accommodates the adhesive agent p inside and is transported on the carton feeding drive unit 8 of the carton feeding unit B. When the cutting blade d of the carton a is attached, the adhesive p
Is to be applied.

Next, as shown in FIG. 12, the die set C1 has a cutting blade forming cutter 11, 11 on the die body 10.
The cutting blade forming cutters 11 and 11 are cut by the cutting blade forming cutters 11 and 11 to cut the strip-shaped material D fed from the introducing portion 10a of the mold body 10 by the cutting blade forming cutters 11 and 11. The band-shaped material D is cut, and the cut side has a sawtooth shape.

The die set C1 is arranged so that the longitudinal direction of the cutting blade d formed thereby coincides with the transfer direction of the carton a, and is formed by the cutting blade forming cutters 11, 11 as shown in FIG. The cut blade d is cut from the upper side as it is to cut the carton a by the cutting blade forming cutter 11.
