According to the present invention, while having a small volume of gas, various components may be organically disposed and packed at a high speed.

According to the present invention, while achieving a robust packaging, the accuracy is high, there is an advantage that can improve the quality of the packaged products.

The present invention relates to a wrap wrapper. Therefore, the configuration and operation of the present invention will be described in detail with reference to FIGS. 1 to 15.

As shown in Figures 1 to 3, the present invention has an elevator unit 100 that can be raised and lowered the packaging tray (3) inside the frame (2) of a large square, unpacking the wrap (1) tray for packaging ( 3) and the wrap packaging unit 200 for wrapping the contents (4) therein is formed. Therefore, these are combined to wrap the wrap (1) through the wrap packaging unit 200 in the upper portion of the tray (3) down the elevator unit 100 to automatically wrap.

In other words, the structural operation of the present invention is to form the elevator unit 100 to move up and down from the center portion of the gas, and to wrap automatically by the wrap packaging unit 200 forming the gas. The elevator unit 100 assists the packaging operation while lifting and lowering as needed in a state where a plurality of contents 4 are loaded into the tray 3. Looking at the packaging sequence, when the operator puts the tray 3 containing the contents 40 on the upper portion of the elevator unit 100, the tray 3 is lowered by riding the elevator unit 100 to the correct position Will catch. And the wrap 1 is moved to maintain the unfolded state on the upper portion of the tray 3, after which the tray 3 is lifted by the elevator unit 100 to the top of the contents 4 and the wrap (1) ) To be in close contact. And the edge portion of the wrap (1) is folded into the bottom of the tray (3) to achieve a complete wrap (1) packaging.

Then, a more specific embodiment of the wrap (1) packaging machine of the present invention will be described in detail with the drawings shown.

The wrap packaging unit 200 already described in the present invention, there is a wrap cutter device 250 for unwinding and cutting the appropriate amount of wrap (1), adjusting the center of the wrapping tray (3) and wrap (1) There is a wrap packaging device 290 which covers the wrap cover from the top of the packing tray 3 and folds the edge of the wrap 1 on the back of the tray 3. That is, the wrap packing machine is formed with a wrap cutter device 290 for cutting the wrap 1 for packaging to a suitable size, wrap wrap to roll the edge of the wrap (1) to the bottom of the tray (3) Device 290 is provided separately. Depending on the size of the tray 3 and the volume of the contents (4) is required a wrap (1) of various sizes, in the present invention by adjusting the size of the wrap (1) first cut to the size for packaging, wrap packaging Packaging is done using the device. A wrap 1 cut to a too large size can increase packaging costs, and a wrap 1 cut too small cannot carry out packaging completely, which in effect can lead to loss of packaging work. Therefore, in order to solve this problem, it is necessary to cut the wrap 1 by setting the correct size first, and to achieve the packaging using the wrap 1. In the present invention, for this purpose, the size of the wrap 1 for cutting is first set by operating the gas, and the data is controlled through a controller.

In any case, the suitably cut wrap 1 is tightly packed so that the front and rear of the tray 3 are not in communication with each other through the wrapping device.

The tray 3 containing the packaged contents is structured in a more tightly adhered state through a separate forming unit 300 located in the upper front of the gas. That is, the tray 3 wrapped in the wrap packaging device 290 is to fix the packaging form through the hot wire forming unit 300 formed on one side of the gas frame (2).

The wrap 1 is made of a thin film of PE material, which is a soft synthetic resin. Therefore, it has a certain elastic force, the surface is in close contact with each other there is a material characteristic that can stick to the contents 4 or the tray 3 without a separate adhesive. By the way, in order to make such a packaging more reliably, when the wrap | lapping 1 overlaps and wraps the package | package part through heat, more reliable packaging is achieved. When the wrap 1 is pressurized to a high temperature so as not to melt, it is deformed according to the temperature, and is firmly bonded to each other and packed. Therefore, the present invention forms a separate hot wire forming unit 300 in front of the hot wire of the gas, the operator moves the packed tray (3) to achieve a perfect packaging only by a slight pressure operation.

Then look at the specific, detailed embodiments that can more easily achieve the above operations in the present invention.

First, the elevator unit for raising and lowering the tray 3 in the vertical direction will be described with reference to FIGS. 1 to 6. The elevator unit 100 has a vertically interlocking hole 111 formed in the support plate 110, which is the upper surface of the base frame 2, and vertically interlocking hole 111 to penetrate the vertically interlocking hole 111 and move up and down. There is a lifting panel 112 is manufactured in the same form as), and there is a lifting cylinder 113 which is fixed to both ends of the lifting panel 112 and the gas frame (2). In addition, the elevating guide rail 114 is formed to penetrate the elevating panel 112 to guide the vertical interlocking of the panel. Therefore, they are coupled to the elevating panel 112 is vertically interlocked with the upper and lower portions of the vertical linking hole 111 through the shaft interlocking of the elevating cylinder 113.

The elevator unit 100 of the present invention operates for the following purposes. First, since the packaging 3 cannot be achieved in the fixed state of the tray 3, the tray 3 is moved downward in the vertical direction to induce the wrap 1 to be unfolded thereon. Then, when the wrap 1 is laid on the upper part, the tray 3 is raised again toward the wrap 1, and the center of the wrap 1 and the contents 4 placed on the tray 3 and It is to perform a close operation. As a result, the elevator unit 100 of the present invention is composed of components that can be vertically interlocked with the upper and lower portions of the vertical linking hole 111 formed in the support plate 110. In the most preferred embodiment, as shown in Figs. 4 to 6, the elevating panel 112 for achieving the elevating is formed, a separate elevating cylinder for elevating the elevating panel 112 ( 113 is mounted.

When the elevating cylinder 113 extends its axis, the elevating panel 112 fixed to the end of the elevating cylinder 113 moves downward along the axis interlocking direction of the elevating cylinder 113. It is coming down. At this time, the important point is interlocked with the guide rail 114 installed in the vertical direction through the elevating panel 112. The guide rail 114 guides the lifting panel 112, which should be raised and lowered through repeated work, to be interlocked in a more vertical direction and improves durability thereof. Two to four guide rails 114 may be installed as necessary, and two lifting cylinders 113 may be formed to have the same shaft interlock.

Eventually, the elevator unit 100 of the present invention, when the elevating cylinder 113 extends the axis, when the elevating panel 112 descends to the lower end of the vertical linking hole 111, and again shrinks the axis, Perform the operation to rise to the top of the vertical link hole (111). Of course, unlike the illustrated figure, if the lifting cylinder 113 is attached to the bottom of the body or a separate lifting means is used, work in the reverse direction is also possible.

By the way, in the present invention, after the elevator unit 100 lowers the elevating panel 112, the wrap 1 is laid on the lower end of the vertical interlocking hole 111. And the elevator unit 100 is operated again toward the lap (1) is thus raised. When the elevating cylinder 113 shrinks its axis in the state where the wrap 1 is laid, the elevating panel 112 fixed to the end of the shaft is lifted by the guide rail 114 to move the vertically interlocking hole 111. It comes up. At this time, a plurality of support bars 130 are fastened to the upper portion of the elevating panel 112, the role of the support bar 130 is to position the tray 3 in the correct position, as a post-work To help the operation of the wrapping device 290 to be followed. Since it will be described later, the link arm portion 270 of the wrapping device 290 pushes the edge of the wrap 1 cut to the lower end of the raised tray 3 so that the end of the wrap and the tray 3 It is glued to achieve a robust packaging. Accordingly, the first and second sealing plates 271 and 272 and the left and right interlocking arms 276 and 277 of the link arm unit 270 to be described later interlock with each other in a horizontal direction, and may be easily bent when the bottom of the tray 3 is hit. It must be manufactured.

That is, the upper portion of the elevating panel 112 in the present invention, the head 120 through the elastic force allows the left and right interlocked, a plurality of support bars 130 to facilitate the wrap (1) is wrapped It is preferable to install. When the left and right interlocking arms 276 and 277 and the first and second sealing plates 271 and 272 are pushed in the horizontal direction, the head 120 of the support bar 130 is bent or bent to allow the linkage. It must be a structure that can

Therefore, an embodiment of a more detailed support bar 130 for this purpose will be described in conjunction with Figures 4-6.

As shown in FIG. 6, the support bar 130 having the head 120 according to the present invention forms a through hole therein, and has an inner diameter at the lower end of the head 120 and the upper end of the support bar 130. There is a tapered surface (121, 131) to narrow the, there is an elastic spring 135 inserted into the inner through hole, each fastening hinge 122 penetrating the body of the head 120 and the support bar 130 , 132 is formed. Therefore, they are coupled, but the upper and lower portions of the elastic spring 135 is fitted into the fastening hinges 122 and 132 penetrating the through holes, so that the head 120 is interlocked in the front, rear, left and right directions through the elastic force of the elastic spring 135. I would have to.

The head 120 is erected through the elastic spring 135 on the top of the support bar 130. In addition, the elastic spring 135 maintains a state embedded in the through hole formed in the inner side of the head 120 and the support bar 130, and is pulled up with each other by using the elastic force. However, when the head 120 is pressurized to the side, as shown in FIG. 15, the head 120 is bent to the other side and bows to the head. 271, the second sealing plate 272 and the left and right interlocking arms 276, 277 are allowed. The reason why this action is important is that when the link arm portion 270 which will be described later wraps the wrap 1 on the tray 3, the corner of the wrap 1 should be folded at all times, because it facilitates this action. . As will be described later, in a state where the upper end of the tray 3 and the contents are covered with the wrap 1, the first and second sealing plates 271 and 272 approach each other in close contact with each other from the front and rear sides of the tray 3. Done. The close contact position is a lower end of the tray 3, and the tray 3 is mounted on the upper head 120 of the support bar 130, so that the head 120 does not interlock. The plate 271 and the second plate 272 will be limited to the linkage. However, since the head 120 of the present invention can be interlocked in the left and right directions by the operation of the elastic spring 135 as shown, when the plate is pushed in, the head plate folds the wrap 1 and the tray 3 is folded. Help fold to the bottom of Similarly, the left linkage arm 276 and the right linkage arm 277 are interlocked with each other when the first hinge 275 is axially secured in order to secure a position adjacent to each other in the left and right directions of the tray 3. Head 120 leans its head and does not limit their operation. According to this action, the tray 3 of the present invention maintains a tightly packed state in which both the upper and lower portions are wrapped with the wrap 1.

In addition, after packaging the tray 3 using the wrap 1, the first contact plate 271, the second contact plate 272, and the left and right interlocking arms 276 and 277 return to their initial positions. Accordingly, no force acts on the head 120 of the upper support bar. In this state, a restoring force acts on the elastic spring 135 so that the head 120 is kept upright on the top of the support bar 130. To this end, at the upper end of the support bar 130 and the lower end of the head 120, tapered surfaces 121 and 131 are formed to decrease the diameter toward the center where the through hole is formed, so that the head 120 is in the left-right direction. It is easy to interlock, but also facilitates the function of restoring and standing up again.

The above described the elevator unit 100 that can be used in the present invention. Therefore, the back of the wrap packaging unit 200 will be described in detail. The wrap packaging unit 200 is composed of a wrap cutter device 250 and a wrap packaging device 290 again.

In the present invention, the elevator unit 100 and the wrap packaging unit 200, the wrap cutter device 250 and the wrap packaging device 290 both achieve a series of operations simultaneously or sequentially to achieve the packaging, the main operation Explain again the way.

First, when the tray 3 for packaging moves to the lower end of the vertical linking hole 111 through the elevator unit 100, the wrap 1 blocking the vertical linking hole 111 is moved. In other words, the tray 3 is moved in a state of being cut into an appropriate size so as to pack the tray 3. Then, the vertical linking hole 111 is blocked through the cut wrap 1, and in this state, the elevator unit 100 rises to raise the tray 3 to the upper portion of the vertical linking hole 111. will be. Since the wrap 1 is already cut in the vertical interlocking hole 111, when the tray 3 rises and penetrates the vertical interlocking hole 111, the tray 3 or the upper portion of the tray 3. The content (4) placed on the ascends while pushing the wrap (1). In other words, the wrap 1 is in close contact with the upper portion of the tray 3 to primarily package. At this time, since all the edges of the wrap 1 are in an unfolded state and only a central portion thereof is raised by the tray 3, the edges of the wrap 1 are folded and closely adhered to the bottom of the tray 3, thereby completing the packing operation. Therefore, in the present invention, the elevator part 100 and the wrap cutter device 250 must all operate organically.

Then, the wrap cutter device 250 for this purpose will be described with reference to FIGS. 7 to 9.

In the wrap cutter apparatus of the present invention, as shown in Figs. 7 and 8, there are a plurality of guide rolls 202 for guiding the movement of the roll 1 and the rotating roll 201 on which the roll-type wrap 1 is placed, and the wrap 1 There is a towing unit 220 for releasing through the towing belt 210 wound around the roll to rotate the left and right both ends of the), there is a power transmission unit 230 for transmitting a rotational force to the towing unit (220). In addition, the cutting portion 240 for cutting the end of the unwrapped wrap (1) is formed. Thus, these are combined to supply a certain amount of wrap 1 to the top of the tray 3.

That is, the wrap 1 is rolled in the form of a roll in the packaging machine of the present invention is coupled to the state that can be released while rotating at the top of the rear. The roll of the wrap 1 is wound on the upper part of the rotation roll 201. Precisely it is located inside the interlocking prevention panel 202-1 formed at regular intervals on the outer circumferential surface of the rotation roll 201. This is to prevent the wrap 1 from falling outside of the interlocking pulley 202-1 when the wrap 1 is rotated and released. And the end of the wrap 1 is released to enter the lower end of the support plate 110 on the outer circumferential surface of the plurality of guide rolls 202, the power is transmitted through the power 230. In addition, since the wrap 1 is in a thin film form, the present invention uses a traction belt 210 to move and unwind the wrap 1. In the state in which the tow belt 210 is interviewed, the surfaces of the wrap 1 and the tow belt 210 are maintained as if the tow belt 210 rotates to maintain the state of being in close contact as if adhered with an adhesive. The interviewed lap 1 of the belt 210 follows the same distance. Therefore, the wrap 1 is pulled by the towing belt 210, and is released while moving on the guide roll 202.

When the wrap 1 wound on the roll is unwound in an appropriate amount, the end thereof needs to be cut. For this purpose, in the present invention, a separate cutting part 240 is formed (shown in FIGS. 7 and 8).

Then look at a more specific embodiment of the wrap cutter device 250.

First, a power transmission unit 230 which is a power for releasing the aforementioned wrap 1 will be described in detail with reference to FIGS. 7 and 8.

In the present invention, the power transmission unit 230, there is a rotary roll 232 is installed in the horizontal direction at regular intervals with the motor 231, the wrap (1) is wound in response to the rotary roll 232 There is a towing roll 233 mounted on the lower end of the rotation roll 201, there is a towing belt 210 is wound in pairs on both the left and right of the rotary roll 232 and the pulling roll 233. In addition, a timing belt 235 is formed to connect the timing pulley 234 formed at the end of the rotary roll 232 and the timing pulley 234-1 formed in the motor 231. Therefore, these are combined to rotate the rotary roll 232 through the rotation of the motor 231, the rotation of the rotary roll 232 rotates the towing roll 233, and the towing belt 210 wound around its outer peripheral surface and The lap belt 1 to be interviewed is horizontally moved to the lower end of the vertical linking hole 111 by the towing belt 210.

That is, looking specifically at the connection structure of the towing belt 210 in the present invention, it is wound on the outer peripheral surface of the towing roll 233 and the rotary roll 232 shown. The rotary roll 232 and the pull roll 233 are coupled to the front and rear of the vertical linking hole 111 formed on the support plate 110 to the base, respectively. A tow roll 233 is formed at the rear at which the movement of the wrap 1 moved to the lower end of the vertical linking hole 111 is formed, and the rotary roll 232 is formed at the front thereof. And the tow roll 210 is shown on the outer circumferential surface of the tow roll 233 and the rotary roll 232 is fastened in a state separated by a distance by the left and right width of the wrap (1). Therefore, when the rotary roll 232 and the pull roll 233 rotates, the pull belt 210 wound around its outer circumferential surface also rotates. In addition, the wrap 1 interviewed with the towing belt 210 also moves forward from the rear of the vertical linking hole 111 while moving by the same distance, thereby preventing the vertical linking hole 111 from the bottom. Figure 9a is a view showing a process of cutting and moving the wrap forward unwrapped, Figure 9b shows a state in which the moved wrap is in close contact with the support plate through the cutting means cut.

At this time, the rotation force of the motor 231 was used in the present invention for the rotation of the traction roll 233 and the rotary roll 232. That is, when the motor 231 rotates, the timing pulley 234-1 fastened to the shaft end of the motor 231 rotates, and the timing pulley 234-1 is fastened to the end of the rotation roll 232. The timing pulley 234 and the timing belt 235 are connected. When the motor 231 rotates, the rotation roll 232 is rotated by the timing pulleys 234 and 234-1 and the timing belt 235.

Eventually, the power transmission unit 230 of the present invention rotates the rotary roll 232 by using the rotational force of the motor, the rotation roll 232 and the corresponding tow roll 233 is rotated, surrounding the outer peripheral surface It works by rotating the towing belt 210.

However, in the ball invention, as shown in FIGS. 7 and 8, the traction belt 233 is equipped with a separate traction pulley 237 for controlling the left and right linkage on the traction roll 233 and the rotation roll 232. It is preferable to wound to the inside of the pulley 237.

That is, a separate pull pulley 237 so that the tow belt 210 to be wound on the rotary roll 232 and the tow roll 233 is interlocked in the left and right direction to hold the left and right edges of the wrap 1 and to be towed. To fix it. Then the towing belt 210 can continue the peristaltic movement without moving in the horizontal direction by the pull pulley 237 fixed to the pull roll 233 and the rotary roll 232. By this pull pulley 237, the pull belt 210 of the present invention can perform a more effective operation.

Next, the towing unit 220 of the power transmission unit 230 of the present invention, the auxiliary rotary roll 222 and the auxiliary towing roll for rotating the additional auxiliary towing belt 221 to the lower end of the towing belt 237. 223 is installed, the auxiliary rotary roll 222 and the rotary roll 232 is preferably engaged through a separate gear 225 fastened to the end.
