The present invention relates to a roll pack manufacturing apparatus manufactured in a roll form so as to easily cut and use a vinyl packaging for putting goods in various stores such as a large store or a supermarket. The present invention relates to a device for winding a bag initially and a vinyl bag breaking device wrapped in a paper pipe that can break along a perforation line of the plastic bag without cutting the plastic bag wrapped in a predetermined amount with a cutting blade. In order to mass produce twice as fast, a single plastic bag supporter and a welding device for lifting and lowering the welding blade and cutting blade up and down are installed in parallel to the frame of the roll pack manufacturing device, and the vinyl packing stand is installed in the paper pipe. The winding device and the device that separates the paper pipe on which the plastic bag is wound from the subsequent plastic bag also frame To be installed in parallel rolpaek relates to a production apparatus to be driven independently of each other.

In general, various businesses are equipped with a plastic bag for putting and selling goods.

The plastic wrapper is provided in the form of a roll pack so that the plastic wrapper continuously wound on the branch pipe can be cut and used by a perforation line.

The roll pack manufacturing apparatus forms a welding line forming blade, a welding line formed by a cutting line forming blade, a cutting line at regular intervals, and winds the vinyl packaging table on which a welding line and a cutting line are formed while feeding the vinyl packaging base paper.

In order to initially wrap the plastic wrapper on the paper pipe of the roll pack manufacturing apparatus, it is necessary to apply a paste to one surface of the paper pipe or wind the plastic wrap on the paper pipe, thereby causing a problem in the automatic operation of the roll pack manufacturing apparatus.

In addition, the paper pipe mounted on the support pipe is slightly shorter than the width of the vinyl wrap wound around the paper pipe, so that the plastic wrap wrapped around the paper pipe protrudes outward from the paper pipe. Therefore, the plastic bag that protrudes outside the paper pipe and is wound on the paper pipe causes pinching of the paper support arm. When the paper packing bag is completely wound, the paper support arm is separated from the paper pipe. The phenomenon is not made smoothly. Therefore, the roll pack manufacturing apparatus has to be temporarily stopped in order to take out the branch pipe which is not easily separated, which is one cause of the decrease in roll pack productivity.

In addition, the first part (Ai) and the last part of the plastic bag wrapped around the paper pipe were cut off the cutting line and the fusion line of the plastic bag with a cutting edge to wind the plastic bag on the subsequent paper pipe. The first part and the last part, namely the plastic bag part used by the roll pack user for the first time, could not be used normally, and it was inconvenient to use it after removing the perforated part. Therefore, there was a problem that the initial use of the plastic packaging wasted. Likewise, the end part of the paper pipe (when the user uses the roll pack) was also cut because it was cut into a portion that is not a perforated line when the paper roll was initially wound.

The present invention was created to solve the above problems of the prior art, it is possible to simply wind the vinyl wrap wound around the paper pipe of the roll pack manufacturing apparatus without being obstructed by the automation operation can simply wind the plastic wrap around the paper pipe It is to provide a winding device.

Another object of the present invention is to provide a cutting device that can easily cut a cut line portion formed in a plastic bag without cutting the plastic bag wound on the branch pipe.

In addition, the present invention is to operate the vinyl packaging base with one driving means to improve the productivity of the roll pack wound around the plastic wrap, while producing a large number of roll packs of different lengths can be wound around the paper pipe, occupy a lot of installation place To provide a roll pack manufacturing apparatus that does not.

In addition, it is to provide a roll pack manufacturing apparatus is made to smooth the bite release of the support pipe and the support pipe after the winding of the plastic wrap in the paper pipe.

This object of the present invention, in a conventional roll pack manufacturing apparatus, it is possible to wind the plastic bag in the beginning of the branch pipe by a nozzle that can inject the compressed air from the bottom of the paper pipe upward and upward from the front of the paper pipe respectively. Is achieved by configuring the device.

In addition, it is achieved by an elastic pressing plate for pressing the welding line and the front and rear portions of the cut line of the vinyl wrap wound around the branch pipe from the top to the bottom, and the pressing plate for pressing the cut line portion located between the pressed vinyl wrap from the top to the bottom.

In addition, it is achieved by mounting a cylindrical stopper on the outside of the branch support arm to prevent pinching of the branch pipe and the branch support arm during the retraction movement of the branch pipe (when it is released from the branch pipe).

In addition, while the supply means for supplying the plastic bag base paper is operated as a single drive means, the drive device for driving the cutting line and the fusion line, and the paper pipe winding device and the device for separating the wound paper pipe are installed in parallel to each other independently This is achieved by working with

Hereinafter, a preferred embodiment for achieving the above object of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a roll pack manufacturing apparatus for manufacturing a welding line / cutting line at a predetermined interval while feeding and feeding a raw sheet of vinyl wrapping material on a feed roll, and then winding the paper tube in a roll pack to produce a roll pack.

Fixed to initially fix the plastic bag on the paper pipe, which consists of nozzles arranged on the lower side and the front of the paper pipe that is gripped and rotated by the support arms supporting both sides of the paper pipe to rotate and driven, respectively, to spray compressed air to the paper pipe side. The device is featured.

In addition, a pair of elastic press plates for pressing the cut line and the cut line of the vinyl wrap wound around the branch pipe and the cut line of the vinyl wrap placed between the press plates and positioned between the press plates are lifted from the top to the bottom to cut the cut lines. It is characterized by a vinyl bag cutting device composed of a pressing plate.

In addition, the vinyl pack paper feeder on the frame of the roll pack manufacturing device, the elevator and sensor for adjusting the discharge position of the plastic wrapper, the welding device to make the vinyl wrap welding line / cutting line, and the paper pipe wound on the paper pipe Installation place by installing the roll pack in parallel with the winding device and the cutting device separating the plastic bag wound on the paper pipe from the subsequent plastic bag, so that the paper feeder is driven by one drive device and the other devices are driven independently. It also occupies less and doubles production.

In general, a roll pack manufacturing apparatus for manufacturing a roll of vinyl wrap around a paper pipe is a winding means for winding the plastic wrap well on the paper pipe, and a cutting blade (also called a cutting knife or cutting blade) after the winding of the plastic wrap on the paper pipe is completed. It consists of a cutting means for cutting out the plastic bag by the discharge.

However, the roll pack manufacturing apparatus of the present invention sprays compressed air toward the branch pipe (newly supported by the support arm) at the upper and lower portions of the branch pipe supporting and driving the branch pipe to wind the cut plastic wrapper on the new branch pipe. The nozzle is installed.

The role of the nozzle is to allow the plastic wrap to wrap around the branch being rotated. In other words, when the paper pipe located in front of the plastic bag transported forward from the rear of the roll pack manufacturing apparatus is seen from the right side of the roll pack manufacturing apparatus (the paper tube rotates in the clockwise direction), the compressed air is moved from the front lower portion of the paper tube to the upper portion. The tip of the vinyl bag (which is transported to the front of the roll pack manufacturing equipment) in which the cutting line of the vinyl bag is separated by the pressing plate is raised to the front upper part of the paper pipe to be rotated, and from the front upper part of the paper pipe to the rear (roll pack manufacturing). Compressed air is injected from the front of the device to the rear side so that the plastic bag is moved behind the paper pipe so that the plastic bag is wound around the paper pipe. At this time, before the operation of the air nozzle for injecting air, it is preferable that the pressurizing roller which is operated up and down by the cylinder installed below the paper pipe is raised to the paper pipe side to press the vinyl packing bag to the paper pipe. This serves to ensure that when the plastic bag is initially wound on the (newly supplied) paper pipe, the plastic bag transported to the lower part of the paper pipe does not fly but is wound around the paper pipe.

The nozzle for injecting air is preferably composed of at least one pair of nozzles arranged at a predetermined width so that the plastic bag having a predetermined width is wound around the branch pipe. For example, the nozzles installed in the lower part and the front part are constituted by a pair of nozzles each disposed at a predetermined width.

On the other hand, as described above, the plastic wrapper wound around the plastic wrapper is initially wound and wound to a predetermined dimension, and then the plastic wrapper wrapped around the paper pipe must be cut or cut to wind the plastic wrapper into another paper pipe.

To this end, the plastic wrap wound around the paper pipe is released from the paper pipe is moved to the discharge device.

The fixed paper pipe is moved to the discharge position, and the plastic bag on the paper pipe side is cut off by the operation of the pressing plate and the pressure plate of the vinyl bag cutting device and separated from the subsequent plastic bag.

The subsequent plastic bag separated from the plastic bag wound by the plastic bag is newly supported on the support arm at the same time as the plastic bag cutting device, and the paper pipe is forwardly fixed by the support roller (or compression roller) under the paper bag. After being wound on the new branch pipe by the lower and front upper nozzle devices, the above operation continues.

The vinyl packing elastic pressing plate, which is operated up and down by a cylinder installed above, presses the front and back of the welding line and the cutting line formed by welding the vinyl packing, and the spring is fitted to the moving plate which is lifted and lowered by the cylinder. And a pair are installed so as to be spaced apart from each other at predetermined intervals. The pressing plate located between the pair of elastic pressing plates is fixedly installed at the lower portion of the moving plate. The pressure plate is slightly lower than the elastic pressure plate on the outer side, which means that the elastic pressure plate first presses the perforation line between the vinyl packing line and the welding line, and then the moving plate is moved downward so that the pressure plate is positioned between the elastic pressure plates. Pressing the perforation line is to separate the plastic bag wound on the branch side and the subsequent plastic bag.

Alternatively, a springless press plate may be used instead of the elastic press plate. The pressing plate is composed of an inverted "U" shape with the lower side interacting with the pressing plate, which is made up of an inverted "U-shaped space. It may be.

 This method using the elastic pressing plate is a method of pressing the pressure plate from the upper side while pressing the plastic bag downward from the top, while the spring-less press plate presses the vinyl bag from the top downward to the pressing plate and simultaneously presses the pressure plate from the bottom. The direction of action of the mutual forces is different in the manner of raising.

In addition, the lower end of the pressure plate is preferably rounded so that the cutting line is not torn and the press is made so that the continuous vinyl packaging is separated from each other.

The upper vinyl packing pressurizing means is preferably configured in the form of a "U" in which the lower part is inverted so as to press the front and rear of the welding line and the cutting line of the vinyl packing. In other words, it is preferable that the welding line and the cutting line of the plastic bag are located between the inverted "U" shape. This is to make it easy to cut the plastic bag by pressing the cutting line located between the inverted "U" shape downward pressure plate from the lower side at the time of the lifting operation. The upper portion of the pressure plate is preferably rounded to press the cutting line to cut the plastic bag.

The operation and action of the apparatus for winding a vinyl packaging bag in the paper pipe of the present invention configured as described above and the vinyl bag cutting device for separating the plastic bag wrapped around the paper pipe from the subsequent plastic packing bag will be described. .

The roll pack manufacturing apparatus of the present invention is a vinyl packaging base paper supplying unit for supplying the plastic packaging base paper to the welding line / perforation line forming means via a plurality of transfer rolls, the vinyl packaging base paper mounted on the supply roll, and the plastic packaging stand The plastic wrapper supplied from the raw paper feeder unit is formed by a dotted line roll pack molding unit which forms a welding line and a cutting line on the base paper, and cuts the cutting line portion of the vinyl wrapping unit after the predetermined amount of the plastic packaging line having the welding line and the cutting line is wound around the paper pipe. It is composed.

The dotted line roll pack molding unit of the present invention can be used in connection with the existing conventionally used roll pack manufacturing paper packaging unit for roll pack manufacturing.

Hereinafter, the roll pack manufacturing apparatus of the present invention will be described schematically. In the roll pack manufacturing apparatus of the present invention, a vinyl packing form supplied from a vinyl packaging base paper supply unit is guided by a plurality of guide rollers, and a welding line is formed by the welding blade of the dotted roll pack forming unit, and then cut through the first elevator. The cutting line is formed by the blade, and then after passing through the second elevator, passing through the servo roller driven by the servo motor, and guided to the take-out roller, a plastic bag having a weld line and a cut line formed between the servo roller and the take-out roller is formed. After that, the plastic bag that has passed through the take-out roller is guided to a plurality of guide rollers in front of the roll pack manufacturing apparatus and wound around the paper pipe by a rotational operation of the support pipe, and the wound paper pipe is cut out of the cut line by the cutting device. At the same time, a new branch pipe is supplied to the branch support arm so that the close blade is wrapped in plastic under the branch pipe. And a close contact, made to the device and the tube incisor supply with plastic packing units following the initial winding of new paper core by sequential operation of the branch pipe and the branch pipe of the lower front front top nozzle and then elevated.

The vinyl packaging bag is continuously supplied from the branch pipe supply unit to the dotted roll pack molding unit, and the servo motor is stopped when the cutting and separation of the cutting line is carried out by winding a predetermined amount of the welding bag and the cut line formed on the paper tube. The dotted line roll pack forming unit is not supplied with the plastic bag base paper. In other words, the vinyl packing bag in which the welding line and the cutting line are formed is struck down long between the servo motor roller and the take-out roller.

The first elevator serves to adjust the position where the tear line is formed after the welding line is formed on the base of the vinyl wrapping material, and the second elevator is the position of the cutting device after the vinyl wrap having the welding line and the tear line is wound around the branch pipe. The pressure plate serves to adjust the pressure accurately. These 1st and 2nd elevators are used in the normal plastic bag manufacturing apparatus, and when the handle is rotated, the screw vertically spaced on both sides rotates, and the vinyl packing installed in the vertical direction to the screw by the rotation operation of the screw The guide rod is moved up and down to adjust the position of the plastic bag transported.

When the roll pack manufacturing device is turned ON, the roll pack welding device with the welding blade and the cutting blade installed with the vinyl wrapping paper supplied from the supply roll through the driving roll of the welding line / cutting line forming means and the upper and lower press rolls are zigzag. By this, the weld line / cut line is molded at regular intervals.

The welding line and the cutting line formed on the plastic bag are operated by the rotation of a circular roll, which is applied by the present inventors at regular intervals, and the welding line / cutting line, which is a commonly used method, is moved up and down. The welding method of rotating in a roll is a method of manufacturing a roll pack having a predetermined length according to the diameter of the roll, but the welding method of raising and lowering up and down can vary the length, thereby manufacturing roll packs of various lengths.

In this way, as the base sheet of the plastic bag formed by the welding line / cutting line is continuously transported through the guide roller, the winding of the plastic bag is automatically performed on the branch pipe supported by the branch support arm, which is the winding means, and driven to rotate.

At this time, the amount of the plastic wrap wound around the paper pipe can be adjusted by sensing the rotation speed of the paper pipe or the length of the plastic wrap.

In this way, when the winding of the plastic wrapper is completed on the paper pipe, the servomotor is stopped, the drive motor of the winding means is stopped, and the rotation operation of the paper pipe is stopped. Then, when the retraction operation of the support pipe support arm is made by the retraction operation of the paper pipe operation cylinder, the holding of the paper pipe wrapped with a predetermined amount of vinyl wrap is released.

In addition, since the paper tube is manufactured to be smaller than the width of the vinyl wrap that is usually wound, the plastic wrapper is wound larger than the width of the paper pipe supported by the paper support arm. Therefore, since the plastic wrapper is rolled up to the outside of the paper tube, the paper tube is pinched by the support arm, and the paper tube is not easily released. However, the roll pack manufacturing apparatus of the present invention is provided with a cylindrical stopper on the outer side of the support pipe located on both sides of the paper pipe, respectively, when the plastic wrapper is wound around the paper pipe when the retracting operation of the paper pipe support arm (bite with the paper pipe) When released, the cylindrical stopper pushes the plastic bag portion protruding outward from the paper pipe to the outside of the paper pipe). Accordingly, the branch support arm continues to move further outward while the stopper presses the plastic bag protruding out of the branch, thereby easily releasing the bite of the branch tube and the branch support arm.

The branch support arm protrudes past the cylindrical stopper when moving to the branch to support the branch, whereas the branch tube is completely rolled up and moved into the cylindrical stopper when the branch support arm moves backward.

In addition, the branch support arm driving means for forward movement and rear movement of the branch support arm is provided with a driving device such as a gear outside the frame of the roll pack manufacturing apparatus supporting the branch support arm and outward from both sides of the frame. Therefore, the branch support arm of the roll pack manufacturing apparatus cannot be connected to one coaxial axis. Therefore, when the branch supporting device is installed horizontally from the same plane, that is, from side to side in parallel, the branch supporting device is arranged in a staggered position forward and rearward, and the branch supporting member driving devices are installed at both sides thereof.

The roll pack manufacturing apparatus of the present invention is a vinyl wrapping paper feeder on the frame, an elevator and a sensor for adjusting the discharge position of the plastic wrapping, a welding device for making a plastic wrap welding line / cutting line, winding the welded plastic wrap on the paper pipe By installing a paper pipe winding device and a cutting device that separates the plastic bag wound on the paper pipe from a subsequent plastic bag, the paper feeder is driven by a single driving device, and the welding device, the paper pipe winding device, and the cutting device are The independent operation takes up less installation space and allows a single manager to manage the roll pack manufacturing equipment, thus doubling production.

The roll pack manufacturing apparatus of the present invention installed in parallel is the same as the operation method of one roll pack manufacturing apparatus. However, the parallel roll pack manufacturing apparatus of the present invention, which is assembled with each roll pack manufacturing apparatus on the left and right sides of the frame, simultaneously drives the plastic bag base feeding value installed in parallel with a single paper feeding driving device, while passing through an elevator and welding device. The plastic bag with the cutout line and the welding line formed thereafter is wound around the guide pipe through the guide roller.

After the winding is completed in the branch pipe, the branch plastic bag and the subsequent plastic bag are usually cut by the cutting blade by a cutting device to separate the plastic bag from the subsequent plastic bag. Are separated from each other.

However, the vinyl bag cutting apparatus as described above, and the apparatus for winding the vinyl tube initially composed of the nozzle can be applied to the roll pack manufacturing apparatus configured in parallel. In other words, the plastic bag supplied in parallel from the base of the plastic bag is guided to a plurality of guide rollers, passes through an elevator, forms a cutting line and a welding line in the welding device, and winds a predetermined amount in the paper pipe to rotate the paper tube rotating device. It is discharged to the discharge device in a temporarily stopped state. At the same time as the discharge, the cutting line of the vinyl bag may be cut by the operation of the vinyl bag cutting device described above.

In other words, in order to set the cutting line of the plastic bag between the pressing plate of the plastic bag cutting device and to be precisely cut by the pressing plate, the height of the guide roller shaft is adjusted by using an elevator. Can be adjusted to match.

On the other hand, it is preferable that a device for supplying a new branch pipe at the time of the operation of the plastic bag cutting device is simultaneously supplied to the branch support arm side.

After cutting of the plastic bag wound on the branch pipe, the branch pipe newly supported on the branch pipe support arm has the vinyl cut out from the front lower part of the branch pipe to the front upper part and the upper rear part by the interaction of the nozzles installed on the lower part and the upper part described above. The pavement is initially wound around the rotating branch pipe. In this way, the plastic wrap wound around the paper pipe is continuously wound without being released by the rotation of the paper pipe being rotated.

Thereafter, the roll pack may be automatically and smoothly produced according to the cut action of the vinyl wrap wound on the paper pipe and the feeding of the paper pipe, and the initial winding of the vinyl wrap cut on the paper pipe is repeated.

As described above, in the present invention, the vinyl wrap wound around the paper pipe of the roll pack manufacturing apparatus is initially wound on the paper pipe, so that the plastic bag is simply wound around the paper pipe by using a nozzle using compressed air. In order to separate the paper pipe from the subsequent plastic bag, the cutout of the plastic bag wrapped in the paper pipe can be used normally without the user's disposal by pressing the cutting line of the plastic bag by pressing means and the pressure plate to move up and down. It has the effect of preventing waste of resources.

In addition, by the cylindrical stopper installed to surround the branch support arm to facilitate the retreat movement of the branch support arm from the plastic wrap wrapped around the outer branch of the branch pipe to have an effect of smoothly discharge operation of the branch pipe. .

In addition, the roll pack manufacturing apparatus is configured in parallel to operate independently, as well as to manufacture roll packs of different lengths, and is installed in a narrow place to double the yield, and the maintenance management of the manufacturing apparatus is very easy.
