Then a fusing board 5 and an insulation receiving board 6 proceed from the front and rear of the object M to be wrapped to joint at an approximate center position differed by width of a cutter 51, and when the film is interposed, the film is sealed and simultaneously fused by a sealing line along selected nichrome wires 55, 56.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention uses a packaging film obtained by winding a cylindrical film into a roll to produce suspended packages, such as processed suits, coats, dress shirts, skirts, etc. This relates to a fully automatic packaging machine for clothing, etc. that wraps clothing by covering it with a film and sealing the top.

[Prior Art] Conventionally, this type of fully automatic packaging machine for clothes, etc. chucks the lower edge of the packaging film guided to the top of the guide frame with a gripper that moves up and down along the guide frame, and then lowers the gripper. After wrapping the package, the packaging film is forcibly pulled down, the film is sealed along the shoulder line of the package, and about 5 mm above it is cut with a cutting blade along the seal line. There was no means to prevent the film from getting caught on the package when it was pulled down, and the cut pieces that were then torn off and fell to the floor were left untouched. In addition, when the gripping body is lowered again after this seal cant to tear off the portion of the film that will not be cut and the sealed portion is aligned with the shoulder of the package, a stop is placed to prevent the film above the cut surface from slipping off. A special brake mechanism was installed to regulate film feed. Furthermore, the hanging hook that suspends the package during wrapping is pivoted in a fixed state with rotation restricted by a spring on a support rod that is pressed by side rollers that support and straighten the film. Packages were delivered by a scooping mechanism that was provided separately from the hook body and oscillated by a push-out block.

[Problems to be Solved by the Invention] As mentioned above, in the conventional fully automatic packaging machine for clothes, etc., the transport of the packaging film is carried out exclusively by forcibly pulling down by lowering the gripper.
It did not have any other active force mechanism to assist film transport. As a result, a strong force is applied to the lower end gripping part and the reversing part of the film, and there is a problem that the film will tear if it is not fed slowly during feeding, which affects the efficiency of packaging work, and furthermore, This results in waste, such as the need to provide a brake mechanism. Further, when the gripping section grips the film and pulls it down, the film gets caught on the packaged object, which significantly reduces work efficiency.

An even bigger problem is that the film is cut with a cutting blade along the seal line, so it can be cut with a cutting blade along the seal line of the film, so
If the seal lines are different, such as one being straight and the other having a V-shape, packaging cannot be completed unless the seal cutting mechanism itself is replaced.

In addition, since the support position of the package support is corrected and maintained by side rollers from both sides, unreasonable force is applied to the film, and extra space is required for the side rollers. Furthermore, the hanging hook that is pivotally supported by the package support is fixed, and the scooping mechanism swings to transfer the package, so the shape and positional relationship between the hook of the scooping mechanism and the hanging hook are important. became extremely delicate, and an adjustment mechanism was required.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention rotates in conjunction with the lowering operation of the gripping section that pulls the lower end of the film to the upper part of the guide frame and lowers the film, thereby actively pulling the film. A film feeding roller is installed to speed up film feeding, and the upper edge of the packaging film is sealed and cut at the same time with a fusing board made of nichrome wire wiring, and a cutting blade installed on the top of the film cuts the seal at the same time. By cutting and arranging irregularly shaped parts, multiple wirings of nichrome wires are used, making it possible to select the sealing wire depending on the packaged item.

In addition, by providing air injection holes in the fusing plate and opening the melted fragment collection pipe at the corresponding position on the insulating receiving plate, sealing,
Fusing, cutting, and air injection were performed simultaneously, and the melted pieces were instantly collected at a predetermined location through a collection pipe. The fusing plate and the insulating receiving plate both move back and forth and are joined at approximately the center of the frame, which is offset by the width of the cutting blade, so the film is not strained and wrinkles are prevented.

The position of the package support is corrected by intermittently pinching it with correction blocks that retract from both sides of the guide frame without using side rollers. The retractable bar swings by itself to deliver and deliver packages.

[Function] When the gripping body that grips both lower edges of the film pulls the film and descends, the film feeding roller provided at the top of the guide frame rotates in conjunction with this, and the packaging is adjusted to match the descending speed. Transports the film. The gripping portion includes a movable plate 47 whose lower end is curved outward and a shielding plate 49 that surrounds the package M to prevent the film from getting caught.

When the grip part descends and passes the lower end of the package, the phototube beam that was blocked by the package is communicated, and the solenoid is activated to stop the grip part from descending.

Next, the fusing plate and the insulating receiving plate advance from the front and back of the package and join at approximately the center position offset by the width of the cutting blade, and when the film is squeezed, the film is sealed by the seal line along the selected nichrome wire wiring. and melted at the same time. At the same time, the upper part of the film is canted by a cutting blade, and the melted pieces of the film are sucked into a collection pipe opening in the insulating receiving plate by air jetted from the air injection hole of the cutting plate, and collected at a predetermined location.

When the seal cut is completed, the retractable bar advances from in front of the hanging hook from which the package is suspended, pushes the hanging hook, and swings and tilts the hanging hook until it reaches the top of the discharge rail. The package hanger detaches from the hanging hook and falls onto the discharge rail, and the package is discharged from the packaging machine. The hanging hook body from which the package has been removed is now pushed by the retractable bar that advances from the rear and swings up to the top of the supply rail, and when it hooks the hanger of the newly supplied package, the retractable bar retreats. The hanging hook returns to its original position due to the gravity of the package.

During this time, the gripping section has been lifted up to the fixed position by disconnecting from the film feed roller by the clutch, and when the packaged item reaches the fixed position, the solenoid is activated to grip the lower edge of the film again, and it starts to descend again. The packaging process begins.

[Example] The present invention will be described in detail below with reference to the drawings.

A is a packaging film that is guided to the upper part of the guide frame 1 by the film meandering prevention guide 11, and is guided to the top of the guide frame 1 by the reversing lever 12.
