Description

  The present invention relates to an automatic cutting / transferring apparatus that reliably cuts a long object such as a conveyed film at a cutting position and transfers the cut piece to another place using a vacuum mechanism. It is.

Conventionally, for example, a cutting means has been presented in Japanese Patent Application Laid-Open No. 2-237794, but the tape-like material protruding from the cutting edge on the side not having the vacuum suction hole into the air is cut down by the cutting edge on the vacuum suction side. Therefore, the tape-like material to be cut is in an unstable state that is only floating in the air, and other fixing means for fixing the tape-like material protruding in the air are necessary for accurate cutting. However, in Japanese Patent Application Laid-Open No. 2-237794, the fixing means is not touched, and the cutting edge having a vacuum suction hole is subjected to R at the tip of the blade, and the other cutting edge is made sharper. Thus, only a device has been shown in which the cut piece after cutting is easily adsorbed to the cutting edge having the vacuum suction hole. Therefore, the tape-shaped material to be cut is in an unstable state in which it is likely to cause a positional deviation that is just floating in the air, and the cut piece that has been thrown into the air also has a vacuum suction hole at an accurate position during cutting. The question remains as to whether or not it can be adsorbed to the cutting edge, and it is speculated that if the cutting edge is dulled by use, the probability of occurrence of the problem increases.
In addition, the technique shown in Japanese Patent Application No. 4-37744 is a technique in which the cut pieces are transported by fluid ejection, and this requires a process of organizing the cut pieces that are skipped when moving to the next process. A problem is expected that the machine configuration and the work process become complicated and the work is not quick.
Furthermore, the technique shown in Japanese Patent Application No. 58-190379 shows a transfer means for adsorbing the cut pieces after cutting. However, since the cut pieces are adsorbed in an unstable state, the cut pieces are scattered and adsorbed. It is easy to guess the disadvantage that it fails to be absorbed or cannot be adsorbed at an accurate position.
As described above, the conventional means can surely cut a long object such as a conveyed film at a cutting position, and can transfer the cut piece to another place without causing any damage. In addition, the present situation is that there is still no satisfactory apparatus that can withstand the automatic continuous operation process.

  The present invention has been made in view of the above-described actual situation, and provides an automatic cutting transfer device that can cut a cutting piece reliably at a cutting position and can transfer a cut piece to another place without damage using a vacuum mechanism. It is the purpose.

The automatic cutting / transferring device according to the present invention includes a conveying device that conveys a long object such as a film to a cutting position, and a longitudinally moving lower blade portion that includes a vacuum mechanism that sucks and holds the leading end of the long object conveyed at the cutting position. And a vertically moving upper blade portion for cutting a long object with the lower blade portion and a transfer hand equipped with a suction mechanism, and the upper and lower moving upper blade portion lowers at the time of cutting, and is held by suction at the lower blade portion at the cutting position. When one end of the long object is cut with the lower blade part, and the cutting blade moves forward and backward with the cutting piece adsorbed after cutting, the transfer hand descends and abuts against the cutting piece. is there.

The automatic cutting / transferring device according to the present invention includes a conveying device that conveys a long object such as a film to a cutting position, and a longitudinally moving lower blade portion that includes a vacuum mechanism that sucks and holds the leading end of the long object conveyed at the cutting position. And a vertically moving upper blade portion for cutting a long object with the lower blade portion and a transfer hand equipped with a suction mechanism, and the upper and lower moving upper blade portion lowers at the time of cutting, and is held by suction at the lower blade portion at the cutting position. When one end of the long object made is cut with the lower blade part, and the cutting blade moves forward and backward with the cutting piece adsorbed after cutting, the transfer hand descends and comes into contact with and adsorbs the cutting piece. Since the cutting piece is transferred through the mutual vacuum means that it is abutted and adsorbed to the transfer hand while it is adsorbed and held by the lower blade part, it is accurate and sure without causing misalignment or scattering and without causing damage. Safe transfer and quick transition to the next process Kill.

According to the automatic cutting and transferring apparatus according to the present invention, when a long length such as a film is conveyed by the conveying device and the leading end reaches a predetermined cutting position, the vacuum mechanism is activated and the leading end of the long object is placed on the lower blade portion. Adsorbed. In this state, the up and down moving upper blade portion is cut and cut, so that it can be cut accurately and reliably without positional deviation or scattering, and there is no positional deviation or scattering after cutting.
After the cutting, when the forward / backward moving lower blade part moves while adhering the cut pieces, the transfer hand descends and abuts and adsorbs to the cut pieces. Therefore, it can be transferred accurately and surely without any displacement or scattering, and it can be safely and quickly transferred to the next process without damaging it. Automatic continuous cutting and transfer of long objects such as film can be performed without stopping the flow.

Hereinafter, the automatic cutting and transferring apparatus of the present invention will be described based on the embodiments shown in the drawings.
In FIG. 1, an automatic cutting / transferring device 1 according to the present invention includes a film 3 conveyed by a conveying device 2 and a lower blade portion 6 having a vacuum mechanism 5 in which a vacuum hole 4 is arranged. When the leading edge 3 a of the film 3 reaches the lower blade portion 6, the vacuum mechanism 5 is activated and the leading edge 3 a of the film 3 is adsorbed to the lower blade portion 6 through the vacuum hole 4. In this state, the upper blade portion 7 that moves up and down is lowered, and one end 3a of the film 3 on the lower blade portion 6 is cut. Thereafter, when a transfer device (not shown) for moving the lower blade 6 forward and backward is activated and the lower blade 6 moves in a state where the piece cut by the vacuum mechanism 5 is sucked, the suction mechanism (not shown) is moved. The transfer hand 8 provided is lowered and brought into contact with the cut piece and lowered to a predetermined position.
In addition, although it applied to the film in the said Example, as long as a vacuum adsorption | suction is possible, what kind of elongate thing may be sufficient.

  The automatic cutting and transferring apparatus of the present invention reliably cuts a long object such as a conveyed film at a cutting position using a vacuum mechanism, and transfers a cut piece to another place using a vacuum mechanism. It is possible to continuously cut a long object such as a film reliably and easily without causing damage, and is suitable for automation of a continuous process.
