Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention uses a packaging film obtained by winding a cylindrical film in a roll shape, and is suspended from a package, that is, a product-processed suit, coat, shirt, skirt, or the like. The present invention relates to a fully automatic packaging machine for clothes and the like, in which the upper part is covered with a film and the upper part is sealed.

[Conventional technology]

Conventionally, this kind of fully automatic packaging machine for clothes etc. chucks the lower edge of the packaging film guided to the upper part of the guide frame with a gripping body that moves up and down along the guide frame, and lowers the gripping body to pack the packaging film. The film is forcibly pulled down, and after the package is wrapped, the film is sealed along the shoulder line of the package, and the top 5 mm is cut with a cutting blade along the seal line. There was no means to prevent it from getting caught in the package, and the cut pieces that were torn off and dropped on the floor were left as they were. Also, after this seal cutting, the gripping body is lowered again to tear off the uncut film part and when the sealed part is aligned with the shoulder of the package, stop so that the film above the cut surface does not slip off, etc. A special brake mechanism was installed to control the film feed. In addition, the hanging hook that suspends the package during encapsulation is axially supported in a fixed state with rotation restrained by springs on the support rod clamped by the side rollers that perform support correction together with the film. The package was delivered by a scooping mechanism that was provided separately from the hook and rocked by an extrusion block.

[Problems to be solved by the invention]

In the conventional fully automatic packaging machine for clothes, etc., the transport of the packaging film is done by the forced lowering of the gripper as described above.
Other than that, it did not have a positive feeding force mechanism to assist the film feeding. As a result, a strong force is applied to the lower end grip and reversal part of the film, and there is a problem that the film will be torn if it is not sent slowly at the time of feeding, which affects the efficiency of the packaging work and a special brake This causes waste such as the necessity of providing a mechanism. In addition, the work efficiency is significantly reduced by the film catching on the package when the gripping body grips the film and pulls it down.

An even bigger problem is that cutting is done with a cutting blade along the seal line of the film, so like a skirt and a suit,
If the seal lines are different, such as a straight line on one side and a V shape on the other side, it means that packaging cannot be done unless the seal cut mechanism itself is replaced.

Further, since the supporting position of the package support is straightened and maintained by the side rollers from both sides, an excessive force is applied to the film, but an extra space for the side rollers is required. Furthermore, since the hanging hook that is pivotally supported by the package support is fixed, and the scooping mechanism swings to transfer the package, the shape and positional relationship between the hook of the scooping mechanism and the hanging hook. Became extremely delicate and the adjustment mechanism for it became unnecessary.

[Means for solving problems]

In order to solve the above problems, the present invention is provided with a film feed roller that rotates in conjunction with the lowering operation of the gripping body that pulls and lowers the lower end of the film on the upper part of the guide frame, and positively feeds the film, A clutch is interposed in the interlocking mechanism, and while the film transfer is regulated by the switching operation, the film roll is fastened to speed up the film transfer, and the seal cut on the upper edge of the packaging film is fused by a nichrome wire wiring. Sealing and fusing cutting were performed at the same time, and a cutting blade provided on top of them cuts and arranges irregular parts due to fusing, and multiple nichrome wirings make it possible to select a sealing line depending on the package.

Further, by providing an air injection hole in the fusing plate and opening the molten fragment recovery pipe at a position corresponding to the insulating receiving plate, a seal,
Melting, cutting, and air injection were performed at the same time, and the molten fragments were instantaneously collected at a predetermined place through the collection pipe. Both the fusing plate and the insulating receiving plate move forward and backward, and are joined at approximately the center position of the frame, which is displaced by the width of the cutting blade, so that the film is easy and wrinkles are prevented.

The package support does not use side rollers, but the position is corrected by intermittently pinching it with the correction blocks that appear from both sides of the guide frame, and the hanging hook is rotatably supported and installed before and after it. The intruder bar was swayed by itself to transfer the package.

[Work]

When the gripping body that holds both lower end edges of the film pulls the film and descends, the film delivery roller provided on the upper part of the guide frame rotates in conjunction with this to deliver the packaging film in accordance with the descending speed. A movable plate 47 and a shield plate 49 whose lower end is curved outward are attached to the package M in the grip body.
To prevent the film from being caught. When the gripper descends and passes the lower edge of the package,
The photoelectric tube beam that was blocked by the package communicates,
The electromagnetic clutch by the solenoid works to stop the lowering of the gripping body. At the same time, the drive motor is switched to the reverse rotation motor to reverse the film roll, and the loosened roll is tightened in the feeding direction.

Next, the fusing plate and the insulation receiving plate advance from the front and back of the package and join at the center position, which is shifted by the width of the cutting blade, and when the film is pinched, the film is sealed by the sealing wire along the selected nichrome wire wiring. It is blown off at the same time. At the same time, the upper part of the film is cut by the cutting blade, and the molten fragments of the film are sucked by the air blown from the air jet holes of the fusing plate into the collecting pipe opening to the insulating receiving plate and collected at a predetermined place.

When the seal cut ends, the retractable bar advances from the front of the hanging hook that hangs the package, pushes the hanging hook, and rocks the hanging hook to the top of the discharge rail to tilt it. The hanger for the package is disengaged from the hanging hook, falls on the discharge rail, and the package is discharged from the packaging machine. The hanging hook with the package removed is now pushed by the retractable bar that advances from the rear and swings to the top of the supply rail, and when the newly supplied package hanger is hooked, the retractable bar retracts, The hanging hook returns to its original position due to the gravity of the package.

During that time, the gripper lifted to the fixed position by disconnecting from the film feed roller by the electromagnetic clutch, when the package reaches the fixed position, the solenoid actuates to grip the lower edge of the film again and starts descending. The packaging process is started again.
