Description

Hand wrapping tool equipped with a rotating holder

The present invention relates to a wrapping machine, and more specifically, to a hand wrapping machine equipped with a rotating holder that can be held by hand and wrap an object.

In general, the film used in hand wrapping machines is a thin film made of polyethylene. The thickness of the wrap used in industrial sites is approximately 18 to 40㎛, but films that are thinner or thicker than this are sometimes used.

Figure 1 shows corrugated cardboard loaded on a pallet. In order to transport such corrugated cardboard, it must be wrapped with a film in a laminated state and fixed so that the laminated state is maintained even if shaken during transportation. In addition, the stacked state of the corrugated cardboard can be maintained stably when lifting a pallet with a forklift, etc., the stacked state can be maintained stably during transportation, and the stacked state can be maintained stably even when unloading or storing after unloading.

To maintain the laminated state, a relatively thick film is wound when wrapping corrugated cardboard with a film. This is to prevent tearing, as the film often tears during winding.

If a relatively thin film does not tear, there is no need to use a thick film.

Film is sold by weight, and the thinner it is, the longer it is for the same weight. Using a thin film can save you money and provide economic benefits, but the more important reason to use a thinner film is that polyethylene film is an environmental pollutant. Because.

The smaller the amount of film used, the less film, an environmental pollutant, is emitted, and less waste is generated after use, which plays a significant role in reducing environmental pollution.

However, when a thin film was used, the film was torn during the winding process, making it impossible to stably fix the fixing object. In other words, it could not function properly as a wrapping film.

Republic of Korea Public Utility Model No. 20-2017-0000830 Republic of Korea Patent Publication No. 10-2012-0105874 Republic of Korea Patent No. 20-300189 Republic of Korea Patent No. 20-46797

The present invention is intended to solve the problems described above. Even if a thin film is used, it prevents it from tearing during the winding process, reduces the amount of film used, reduces film winding costs, and reduces the emission of environmental pollutants. To prevent the film from rattling when released from the fixed holder or from poor rotation due to the inner surface of the paper tube rubbing against the surface of the fixed holder, a rotating holder that rotates along the outer circumference of the fixed holder is provided to ensure that the film is released smoothly. We would like to provide a hand wrapping machine equipped with a rotating holder.

In order to achieve the above object, the present invention is a hand wrapping machine that is equipped with a paper tube wrapped with a film and fixes the fixative body by wrapping it with a film. The present invention is provided with a gap that allows both ends of the paper tube to be inserted, and a rail groove is formed on the outer circumference. A pair of left and right fixing holders; Left and right rotating holders are inserted into and rotated on the outer surfaces of the left and right fixing holders, and are formed with ring protrusions that engage with the rail grooves and rotate along the rail grooves to prevent vibration while rotating; A left holder bracket coupled to the outer surface of the left fixing holder and having both ends protruding outside the left fixing holder; A right holder bracket coupled to the outer surface of the right fixing holder so that both ends protrude to the outside of the right fixing holder and each of the protruding portions has two holes formed therein; a rear guide rod, one end of which is coupled to the left holder bracket and the other end of which is inserted and extended into a hole of the right holder bracket; two front guide rods, one end of which is coupled to the left holder bracket and the other end of which is inserted and extended into a hole of the right holder bracket; A handle inserted into the hole of the right holder bracket and coupled between the ends of the extended rear guide rod and the front guide rod; A spring is inserted into the rear guide rod and the front guide rod between the handle and the right holder bracket, the front end is coupled to the right holder bracket, and the rear end is coupled to the handle to elastically support the right holder bracket; A hand wrapping machine equipped with a rotating holder is provided.

When the hand wrapping machine according to the present invention is used, both ends of the film unwound from the paper pipe can be overlapped in the form of wrinkles, thereby preventing both ends of the film from being torn while wrapping a fixed body such as corrugated cardboard.

Due to this function of preventing both ends of the film from being easily torn, a relatively thin film can be used when wrapping cargo such as laminated corrugated cardboard with film and fixing it so that it does not fall apart during transportation, thereby reducing the film purchase cost by reducing the amount of film used. In particular, the amount of film used is reduced, which can greatly reduce the emissions of environmental pollutants generated when discarded after use.

In addition, since the paper tube is inserted into a rotating rotary holder rather than a fixed holder, the film is prevented from shaking when unwound, and unwinding is smooth because there is no rotational friction between the paper tube and the rotating holder. Therefore, the work is convenient and faster when winding the fixed body, and worker fatigue is greatly reduced.

In addition, the paper pipe can be more easily mounted on the hand wrapping machine, and it is easy to handle, so anyone can easily use the hand wrapping machine.

Figure 8 is another embodiment of the hand wrapping machine according to the present invention.

The present invention will be described with reference to the attached drawings as follows.

As shown in Figures 1 to 8, a cylindrical paper tube on which a film is wound is provided. Cylindrical branch tubes with film wound on them are standardized according to the length of the film and are sold in various ways on the market.

A left fixing holder (110a) and a right fixing holder (110b) are provided that are inserted into both ends of the branch pipe and hold the branch pipe. The left and right fixing holders 110a and 110b are formed of a cylindrical bar 112 and a flange 114, and a rail groove 116 is formed along the circumference of the cylindrical bar 112.

The left and right fixing holders (110a, 110b) have a ring that rotates along the rail groove (116) while engaging with the rail groove (116) to prevent vibration (vibration) in the longitudinal direction along the cylindrical rod (112) while rotating. Left and right rotating holders (210a, 210b) formed with protrusions (220) are assembled. The left and right rotating holders (210a, 210) are composed of a cylindrical rod 212 and a flange 214, and a ring protrusion 220 is formed on the inner circumference of the cylindrical rod 212 by protruding to correspond to the rail groove 116. .

The ring protrusion 220 uses a hard yet elastic member so that the cylindrical rod 212 of the left and right rotating holders 210a and 210b can be inserted into the cylindrical rod 112 of the left and right fixed holders 110a and 110b. Even if there is interference, it is compressed, and when it meets the rail groove 116, it protrudes and engages strongly, so that if an external force of more than a certain size is not applied in the longitudinal direction while the ring projection 220 rotates in the rail groove 116, the ring projection 220 The ring protrusion 220 continues to rotate along the rail groove 116 while preventing it from leaving the rail groove 116. Therefore, if there is no rail groove 116 and ring protrusion 220, the left and right rotating holders (210a, 210b) may vibrate in the longitudinal direction when rotated while assembled to the left and right fixed holders (110a, 110b). This phenomenon This is prevented.

A cushion member ring groove 230 is formed on the outer periphery of the cylindrical rod 212 of the left and rear rotating holders 210a and 210b. The cushion member ring 240 is inserted into the cushion member ring groove 230. The lower part is inserted into the cushion member ring groove 230, and the upper part has the cushion member ring groove 230 protruding outward, so that the left and right rotation holders 210a, Even if a branch pipe having a relatively larger inner diameter than the outer diameter of the cylindrical rod 212 of 210b) is inserted, the left and right rotating holders 210a and 210b are rotated by elastically supporting the cushion member ring 240 while compressing the gap difference. When doing this, make sure that the branch pipes rotate together instead of slipping and turning. In addition, a plurality of elastic metal bars 250 in the form of narrow bands with excellent restoring force are embedded in the cushion member ring 240 at regular intervals. The elastic metal bar 250 is a thin metal plate, and when pressure is applied to the cushion member ring 240, it is compressed elastically and an elastic repulsion force is formed, so that when the branch pipe is inserted, only the cushion member ring 240 is left on the inner surface of the branch pipe. It adheres more strongly to the inside of the paper pipe than before, preventing the paper pipe from turning around. The elastic metal bar 250 may be made of a synthetic resin sheet with excellent elasticity.

In another embodiment, there are at least two locations at intervals on the inner circumference of the right and left rotating holders (210a and 210b) corresponding to the rail grooves (116) formed in the cylindrical rods (112) of the left and right fixing holders (110a and 110b). A ball hole 270 is formed. A ball 280 elastically supported by a spring 290 is inserted into the ball ball 270, and the left and right rotating holders (210a, 210b) are inserted into the right fixed holders (110a, 110b) with a portion of the ball 280 protruding. ) When inserted and assembled, the spring 270 is compressed and the ball 280 enters the ball ball 270. When the ball 280 meets the rail groove 116, the ball 280 protrudes by the elastic force of the spring 290. When (280) engages with the rail groove (116) and the left and right rotating holders (210a, 210b) rotate along the left and right fixed holders (110a, 110b), the ball (280) rotates along the rail groove (116) to the left. , Ensure that the right turn holders (210a, 210b) do not deviate from their designated positions.

A left holder bracket 120a is formed on the outer surface of the left fixing holder 110a, with both ends protruding outward from the left fixing holder 110a in the radial direction.

On the outer surface of the right fixing holder (110b), a right holder bracket (120b) is formed with both ends protruding outward from the left fixing holder (110a) in the radial direction. The right holder bracket 120b has two holes formed on protruding portions on both sides.

A pair of rear guide rods 130 are formed in parallel at the rear between the left holder bracket 120a and the right holder bracket 120b. One end of the rear guide rod 130 is coupled to a protruding portion of the left holder bracket 120a, and the other end is inserted into and extends into a hole of the right holder bracket 120b. The rear guide rod 130 is formed in two pieces at regular intervals, but only one can be formed.

A pair of front guide rods 140 are formed in parallel on the front side between the left holder bracket 120a and the right holder bracket 120b. One end of the front guide rod 140 is coupled to a protruding portion of the left holder bracket 120a, and the other end is inserted into and extends into a hole of the right holder bracket 120b. The pair of front guide rods 140 are formed in two parallel rows at regular intervals. In this way, the right holder bracket 120b can slide up and down along the rear guide rod 130 and the front guide rod 140 through the hole.

A handle 150 is formed that connects the ends of the rear guide rod 130 and the front guide rod 140 to each other. The handle 150 can be held when carrying a hand wrapping machine or wrapping it with a hand wrapping machine.

A spring 160 is inserted between the rear guide rod 130 and the front guide rod 140 between the right holder bracket 120b and the handle 150. The front end of the spring 160 is coupled to the right holder bracket (120b), and the rear end is coupled to the handle 150, and the right fixing holder (110b) is integrally coupled with the right holder bracket (120b) while hanging from the handle (150). ) is holding. When the hand wrapping machine is set up with the handle 150 facing upward, the spring 160 is suspended from the handle 150 and the forward and backward guide rods are moved to the point where the load of the left fixing holder (110a) and the tension of the spring (160) are balanced. It is in a state of being stretched along, and when the right fixing holder (110b) is pushed up, the spring (160) is compressed and has an elastic support force.

A film guide 170 is formed on the bottom of the right holder bracket 120b into which the front guide rod 140 is inserted and the upper surface of the left holder bracket 120a. In the film guide 170, two rod holes are formed at an interval equal to the distance between the two front guide rods 140 so that the front guide rod 140 can be inserted, so that the front guide rod 140 is inserted into the front guide rod 140. It is possible to slide up and down along the rod 140.

A rotating roller is formed at the longitudinal end of the film guide 170 to prevent damage to the film being released from the paper tube as it rotates. When the rotating roller does not rotate, the film makes sliding contact with the surface of the rotating roller, but when the rotating roller rotates, it makes rolling contact, preventing damage from friction during the film unwinding process and unwinding it more smoothly.

At the lower part of the film guide 170 formed on the bottom of the right holder bracket 120b, a stopper 180 is installed on the front guide bar 140 to prevent the film guide 170 from descending more than a certain distance along the front guide bar 140. ) and insert it. That is, the film guide 170 tries to go down along the front guide rod 140 by the spring 160, but the stopper 180 blocks it, so it cannot go down any further and is fixed in contact with the stopper 180.

The film guide 170 is in contact with the upper surface of the left holder bracket 120a and is inserted into the front guide rod 140. However, when using a hand wrapping machine, the handle 150 is used with the handle 150 facing upward, so when using it, the front guide rod 140 is always used. ) It goes down to the bottom.

A short spring 190 is inserted into the front guide rod 140 between the film guide 170 and the left holder bracket 120a, which is in contact with the left holder bracket 120a, so that the film guide 170 is elastically supported.

The length of both the film guide 170 in contact with the left holder bracket 120a and the film guide 170 in contact with the right holder bracket 120b is approximately 20 to 30 mm longer than the flange thickness of the left and right fixing holders 110b. This means that when the paper tube with the film wrapped around it is inserted between the left and right fixing holders (110b), both ends of the film are in close contact with the flange, and the rotating roller of the film guide (170) is located about 20 to 30 mm toward the center rather than the both ends of the film. The gap between the upper and lower film guides 170 is 40 to 60 mm shorter than the width of the film.

The operation of the hand wrapping machine according to the present invention configured as described above will be described as follows.

Insert one side of the film-wrapped paper tube into the cylindrical rod of the right-turn holder (210b). When the right turn holder (210b) is raised from bottom to top, the front and rear guide rods (130) slide and rise along the spring (160), compressing the spring (160) and expanding the space below it. When one side of the branch pipe is inserted into the cylindrical rod of the right rotating holder (210b), the upper end of the branch pipe is in close contact with the flange of the right rotating holder (210b), and the other lower end of the branch pipe is aligned with the cylindrical rod of the left rotating holder (210a). Since the right fixing holder (110b) of the branch pipe inserted between the left rotating holder (210a) and the right rotating holder (210b) is elastically supported by the spring (160), the branch pipe is also elastically supported by the spring (160).

In addition, the left and right rotating holders (210a, 210b) are rotated by engaging the ring protrusions (220) and the ring grooves (116) while being inserted into the left and right fixed holders (110a, 110b), so the branch pipes are also rotated in the left and right rotating holders (210a, 210b). are rotated together along 210b). In addition, since the ring protrusion 220 is rotated along the ring groove 116 while engaged with the ring groove 116, the left and right rotating holders 210a and 210b rotate along the cylindrical rod 212 without vibrating up and down.

While holding the handle 150 with one hand and the left holder bracket 120a with the other hand, pull and attach the film to the corrugated cardboard laminated on the pallet as shown in FIG. 1, and release the film while pulling to release the corrugated cardboard. wraps around.

Since the film unwound from the paper tube is passed between the two front guide rods 140, the front guide rod 140 functions to unwind the film stably.

When the film is unwound from the paper tube, both ends of the film first pass through the rotating roller of the film guide 170. Since the rotating roller is located about 2 to 3 cm inside the side end of the film, both ends of the film are is pushed inward by about 2 to 3 cm and overlaps to form a wrinkle area. As the films overlap, they form wrinkles like a folding fan, and since polyethylene films have the property of sticking when overlapped, the overlapped parts become multiple layers and the film becomes thicker. In other words, as the width of the film decreases by (T1 - T2), both sides of the film overlap, becoming thicker and tougher, so it does not tear during the wrapping process.

In this way, if both ends of the film become thicker, the both ends of the film will not be torn when wound on corrugated cardboard. So, by reducing the thickness of the film wound on corrugated cardboard, we wanted to reduce the capacity of the film and reduce the emission of environmental pollutants by reducing the thickness of the film wound on corrugated cardboard. The thickness, which could not be reduced because both ends of the film were torn during the winding process, was solved through a film guide 170 that forms wrinkles at both ends of the film. In other words, a relatively thinner film can be used, which greatly reduces the amount of film used.

When the film wound around the paper tube is used up, the right fixing holder (110b), which is elastically supported by the spring 160, can be pushed upward to separate the paper tube and then be replaced.
