Description

Bonding and cutting device for wrapping paper {Cutting and Heating Apparatus of Wrapping Paper}

The present invention relates to a bonding and cutting device for a wrapping paper, and more particularly to a bonding and cutting device for a wrapping paper to perform the cutting and bonding function of the wrapping paper in connection with the movement of the wrapping paper.

The object to be packaged may be solid foods such as confectionery and meat, as well as liquid contents, and packaging films of various materials are applied according to the type of the object to be packaged.

Prior art related to a film supply device for supplying a packaging film manufactured as described above to a packaging machine is described in Korean Patent Registration No. 10-1012583 "Film Supply Device and Packaging Device Equipped With It" (Registration Date: 2011.01.26) As shown, the film supply mechanism has a supporting member for holding the first portion of the film on the air side and a bonding sealer for bonding the films, so that the cut film and the film on the air side are bonded and bonded by the bonding sealer. The two films are connected and supplied.

However, the packaging machine side supply device of the existing packaging film needs to be continuously supplied to the packaging machine side, and for this purpose, a bonding mechanism including a separate bonding sealer must be provided, and in this case, a heating means such as a heater is used for thermal bonding. In addition to being built-in, since a driving source such as an air cylinder is required for moving forward and backward of the bonding sealer, there is a disadvantage in that the structure is not only complicated, but also causes a high production cost at a high cost of the supply device.

In addition, since the supply of the packaging film is stopped for the time required for joining, the packaging operation of the packaging machine is not continuous, and thus the workability is lowered.

First, as shown in FIGS. 1 to 7, the wrapping paper 11 is withdrawn from the winding roller (not shown) a plurality of times and is provided as a package cutting and bonding device.

At this time, the wrapping paper 11 is provided in a state where both sides are joined to provide a space therein.

The joining and cutting device for the wrapping paper cuts the wrapping paper 11 according to the volume of the object to be packaged, and bonds the cut portions by instant heat welding.

To this end, the packaging paper cutting and joining apparatus of the present invention comprises a joining portion 100 and an operating portion 200.

The first and second shafts 130 and 130 are installed to face the bonding portion 100 vertically, and the cutting and welding mechanism 110 composed of cutting means 114 and bonding means 115 are installed to face the first shaft 120 and the second shaft 130 to face each other. The reverse rotation of the first axis 120 and the second axis 130 cuts and bonds the wrapping paper 11, which moves while the pair of cutting and welding mechanisms 110 are in close contact with each other.

The operation part interlocks with the reverse rotation motions of the first and second axes, and at the same time, reciprocates the joint to a trajectory having a curvature in connection with the moving speed of the wrapping paper, and continuously cuts and fuses the cutting and welding according to the cutting position of the wrapping paper. Try to place it repeatedly.

First, the junction 100 will be described below.

The first shaft 120 and the second shaft 130 are installed to be spaced apart from each other vertically.

And, the first and second shafts 120 and 130 are cut and fused mechanisms 110 are installed, respectively, and the first and second axes 120 and 130 are rotated by a pair of cut and fused mechanisms 110 interlocking, so that their mutual positions coincide. At the point in time, the wrapping paper 11 is cut and joined.

To perform this operation, the first gear 121 is installed at one end of the first shaft 120, and the second gear 131 meshing with the first gear 121 is installed at the second shaft 130.

Then, the pulley 143 is installed on the first shaft 120 through the transmission means 140 to receive the driving force of the motor 142 to the belt 141 to reversely rotate the first shaft 120 and the second shaft 130.

In addition, a specific configuration for the installation of the cutting and welding mechanism 110 installed on the first shaft 120 and the second shaft 130 is as follows.

The first plane 120 and the second shaft 130 are respectively installed on the first flat portion 125 formed on the outer circumferential edges, but the lower surface of the cutting and welding mechanism 110 is formed with the second flat portion 111 and the first flat portion 125 and the surface. It is in close contact with each other, and a clamp 112 is formed to protrude on both sides of the cutting and welding mechanism 110 to integrally fix the pair of cutting and welding mechanisms 110 through the fixing means 113.

Then, the electric wire provided from the outside is connected to the cutting and welding mechanism 110 through the guide holes formed on the first shaft 120 and the second shaft 130 to heat the cutting means 114 and the bonding means 115 installed on the cutting and welding mechanism 110 through electrical resistance. .

That is, the cutting means 114, the cutting and welding mechanism 110 is connected to the electric wire to generate heat to have a temperature for cutting the wrapping paper 11.

In addition, the joining means 115 are respectively installed on both sides of the cutting means 114 and connected to an electric wire to generate heat to have a temperature for joining the wrapping paper 11.

Here, heat is generated according to the set temperature such as the cutting temperature and the welding temperature of the wrapping paper 11 of the cutting means 114 and the bonding means 115.

The joining means 115 configured as described above is a second gear in which the driving force of the motor 142 having a rotational speed associated with the moving speed of the wrapping paper 11 is input to the first gear 121 of the first shaft 120 through the pulley 143 and the belt 141. 131.

Through this, the first shaft 120 and the second shaft 130 rotate in a mutually reverse rotation, and the first shaft 120 and the second shaft 130 rotate in cooperation with the cutting and welding mechanism 110 composed of the cutting means 114 and the joining means 115.

In addition, the pair of cutting and fusion mechanisms 110 that generate heat through electrical resistance are matched with each other at the time of rotation, so that the wrapping paper 11 is cut at the same time and joined by heat fusion.

At this time, the junction part 100 reciprocates through a moving part 200 in a trajectory having a curvature in connection with the moving speed of the wrapping paper 11.

To enable this, the junction part 100 is disposed and coupled to the first bracket 150 and the second bracket 151 supporting rotation of the first axis 120 and the second axis 130, and the first bracket 150 and the second bracket 151, respectively. The first guide plate 160 and the second guide plate 161, which are spaced through the bar 162, are rotatably coupled to the first guide plate 160 and the second guide plate 161 and fixed to the lower center of the first bracket 150 and the second bracket 151. In the first guide plate 160 and the second guide plate 161, the first bracket 150 and the second bracket 151 are composed of a rotating shaft 165 that reciprocates.

Through this, the first guide plate 160 and the second guide plate 161 are supported on the first bracket 150 and the second bracket 151 around the rotation axis 165 to repeatedly perform the pendulum motion.

In addition, the first axis 120 and the second axis 130 are mounted on the first guide plate 160 and the second guide plate 161 to interlock the pendulum movement.

The junction 100 enables reciprocating movement with a short movement trajectory. That is, the joint portion repeatedly performs a pendulum motion.

Here, the pendulum motion means that the first guide plate 160 and the second guide plate 161 rotate reciprocally at regular intervals around the rotation axis 165.

This shortens the stroke for the movement of the joint 100 by converting the process of the linear reciprocating motion of the joint 100 into a pendulum motion in the invention previously filed by the applicant of the present invention, thereby improving mechanical motion efficiency.

That is, it is possible to improve the accuracy of the bonding and cutting operation of the film by minimizing the shaking of the bonding and cutting device by shortening the moving distance.

In addition, since the moving distance is shortened, it is possible to bond and cut more films faster, thereby improving the efficiency of product production.

In addition, when a sufficient bonding and cutting time is given when bonding and cutting the existing film, a phenomenon in which the film is fused to the surface of the bonding portion occurred.

Through this, a large accident occurred in which all processes of supplying, cutting, and bonding of the film were stopped, thereby shortening the life of the machine, but the present invention prevents the film from being fused by bonding and cutting the film instantaneously. It has the effect of minimizing the load on the machine and enabling smooth performance of the film process.

In addition, the operation unit 200 is connected to the operation of the reverse rotation of the first axis 120 and the second axis 130 in conjunction with the moving speed of the wrapping paper 11 to reciprocate the junction 100 in a pendulum motion manner to continuously supply the wrapping paper 11 The cutting and welding mechanism 110 is repeatedly positioned according to the cutting and joining positions.

The operation unit 200 to enable this is composed of a driving means 210, a rotating plate 220, a link 230 and a crankshaft 240.

The driving means 210 may be a motor 142 or a cylinder, and generates rotational force.

At this time, the rotational force provided by the motor 142 or the cylinder is adjusted through the speed reducer.

The rotating plate 220 is connected to the driving means 210 or the reducer to rotate.

The link 230 is eccentrically coupled to the upper surface of the rotating plate 220, but is rotatably coupled.

Then, the crankshaft 240 is connected to the link 230 and the rotating shaft of the junction 100 to repeat the pendulum motion of the junction 100 through the rotational force of the driving means 210.

That is, when a rotational force is generated by the driving means 210, the number of revolutions is adjusted through a reduction gear, and the reduction gear and the electrically connected rotating plate 220 rotate by interlocking the link 230.

At this time, the link 230 is installed eccentrically on the rotating plate 220, one end of the crankshaft 240 interlocks, and moves up and down.

In addition, the rotating member 155 is repeatedly reciprocated at a constant angle by the connecting member 241, which is connected to the rotating shaft 165, and is connected to the rotating shaft 165 to be angularly deformed on the upper portion of the crank shaft 240.

The bonding unit 100 and the operation unit 200 configured as described above continuously link the moving speed of the wrapping paper 11 with the reciprocating speed of the bonding unit 100.

That is, the time when the joint 100 moves in the pendulum movement direction and speed in the process of moving the wrapping paper 11 and the time when the cutting and welding mechanism 110 installed on the first axis 120 and the second axis 130 rotate and coincide with each other are coincident. .

This is called instantaneous fusion time in the present invention.

In the present invention, the instantaneous fusion point as described above is to perform the cutting and joining function using the heat of the cutting means 114 and the joining means 115 during the time that the wrapping paper 11 and the joining part 100 move the same.

Through the above-described method, the joining portion operates through a pendulum motion in connection with the movement of the wrapping paper, and at the same time, the time when the cutting and welding mechanism rotates counterclockwise is repeated to continuously repeat the joining and cutting.

In addition, the gap between the first axis 120 and the second axis 130 can be freely adjusted according to various thicknesses of the wrapping paper 11.

To this end, the second bracket 130 is fixed to the first bracket 150 and the second bracket 160, and the first shaft 120 is installed to be movable up and down.

This is to adjust the gap between the first axis 120 and the second axis 130 according to the various thicknesses of the wrapping paper 11.

For this, a height adjusting means 300 is provided.

The height adjustment means 300 are respectively installed on both sides of the first axis 120 to adjust the heights of both ends of the first axis 120.

The height adjustment means 300 includes a first fixing block 310, a second fixing block 320, a moving bar 330, a locking block 350 and an elastic member 340.

The first fixing block 310 is fixed to the first bracket 150 and the second bracket 160, respectively.

Then, the second fixing block 320 is fixed to the side of the guide block 155.

In addition, the moving bar 330 vertically penetrates the first fixing block 310 and the second fixing block 320, but is screwed to the first fixing block 310.

Through this, through the rotation of the moving bar 330, the lid moves to the upper or lower side by screwing.

The locking block 350 is fixed to the moving bar 330 between the first fixing block 310 and the second fixing block 320 and fixed to the moving bar 330 exposed under the second fixing block 320.

In this case, the elastic member 340 is installed between the locking block 350 and the second fixing block 320 fixed to the moving bar 330, the locking block 350 interlocking with the moving bar 330 moving in the lead elastically changes the pressing force applied to the elastic member 340. .

Consequently, the operation for lowering the first axis 120 in the downward direction is as follows.

First, when the moving bar 330 is rotated, the moving bar 330 screwed with respect to the first fixing block 310 vertically moves in the downward direction.

At this time, the second fixing block 320 is lowered by the elastic force of the elastic member 340 installed between the second fixing block 320 and the locking block 350, and the first bracket 150 or the second bracket 160 is interlocked to the lower portion to form the first shaft 120. Make it possible to move downward.

Conversely, the operation for raising the first axis 120 in the upper direction is as follows.

When the moving bar 330 is rotated in the opposite direction, the screwed moving bar 330 moves vertically in the upper direction based on the first fixing block 310.

At this time, while the locking block 350 supporting the lower portion of the second fixing block 320 interlocks, the second fixing block 320 is moved upwards and the elastic member 340 is compressed.

Through this, since the position of the first axis 120 can be moved upward or downward, the vertical position of the first axis 120 can be adjusted, so that the distance between the second axis 130 can be freely adjusted to suit the various thicknesses of the wrapping paper 11. Have compatibility to perform cutting and joining functions.

The bonding and cutting device for the wrapping paper of the present invention configured as described above has the following technical features.

First, in the invention previously filed by the applicant of the present invention, a process for linearly reciprocating the joint portion 100 is converted to a pendulum motion to shorten the stroke for the movement of the joint portion 100, thereby improving mechanical motion efficiency.

That is, it is possible to improve the accuracy of the bonding and cutting operation of the film by minimizing the shaking of the bonding and cutting device by shortening the moving distance.

In addition, since the moving distance is shortened, it is possible to join and cut more packaging papers faster, thereby improving the efficiency of product manufacturing.

In addition, when sufficient bonding and cutting time are given when bonding and cutting the existing wrapping paper, a phenomenon of fusion to the surface of the bonding portion of the wrapping paper occurred.

Through this, a large accident occurred in which all processes of supplying, cutting, and bonding of the wrapping paper were stopped, thereby shortening the life of the machine, but the present invention prevents the film from being fused by bonding and cutting the wrapping paper instantaneously. It has the effect of minimizing machine load and enabling smooth performance of the packaging process.
