The present invention relates to a stretch film wrapping apparatus, and more particularly, by improving the stretch film wrapping apparatus used for the packaging of export goods or the production packaging of products, thereby preventing waste of packaging materials and reducing packaging time. It can be, and relates to a stretch film wrapping apparatus that can reduce the packaging cost.

1 and 2 are schematic diagrams for explaining the operation of the conventional stretch film wrapping apparatus. 1 is a state in which the lap head attached to the master portion is raised to the upper portion of the master portion, Figure 2 shows a state in which the lap head portion is lowered. The stretch film wrapping device 10 is a device for wrapping, i.e., wrapping an export or product 60 using the wrap 17.

1 and 2, the conventional stretch film wrapping apparatus is a form in which the wrap head portion 12 and the cutting and sealing portion 13 are attached to the fixed master portion 11, respectively. The wrap head portion 12 is a portion of the wrap unrolled so that the wrap 17 wound in a roll form can be placed therein to wrap the product in a wrap. As the turntable 15 rotates, the product 60 located above the turntable 15 rotates. As the product rotates, the wrap 17 wound around the roll is released to wrap the product in a wrap. The wrap head portion 12 is attached to the master portion 11 and moves up and down to wrap the product in a wrap.

The cutting and sealing portion 13 is a portion that serves to cut the wrap and attach the end of the wrap after wrapping the product in the wrap by the wrap head portion 12. Since the conventional cutting and sealing portion 13 is fixedly attached to the master portion 11, it is driven by the cylinder 14 only when the lap head portion 12 is lowered again in one up and down reciprocation movement. Go to the product, cut the wrap and attach the end of the wrap.

As such, in the conventional stretch film wrapping apparatus 10, as illustrated in FIGS. 1 and 2, the wrap head portion 12 and the cutting and sealing portions 13 are separately attached to the master portion 11. It is. The lap head part 12 can reciprocate up and down, but the cutting and sealing part 13 is fixedly attached to the lower end of the master part 11. Therefore, the wrapping of the product is completed only when the wrap head 12 is reciprocated once by the vertical movement. In other words, the packaging process of one cycle is completed only when the wrap head 12 is raised to the top and then lowered to the bottom again. Accordingly, the conventional stretch film wrapping apparatus has a disadvantage in that the packaging material is wasted due to the overlapping packaging by the reciprocating motion of the wrap head, regardless of the type and weight of the package, and the packaging time takes a lot.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a stretch film wrapping apparatus that can wrap a product without double wrapping the product by the reciprocating motion of the wrap head unit once.

Another object of the present invention is to provide a stretch film wrapping apparatus that can reduce the packaging material (wrap) is excellent in economic efficiency, and can reduce the packaging time.

Still another object of the present invention is to provide a stretch film wrapping apparatus capable of packaging one or two or more layers of a product in a wrap at the user's option.

In order to achieve the above object, the stretch film wrapping apparatus according to an embodiment of the present invention, the wrap head portion and the wrapping of the product is wrapped by attaching the master part and moving up and down along the master part In the stretch film wrapping apparatus for wrapping the product in a wrap having a cutting and sealing portion for cutting and attaching the wrap after finishing,

The cutting and sealing parts are not fixedly attached to the master part but fixedly attached to the lap head part so that the lapping process can be completed even after the lap head part moves from the lower part to the upper part without performing one reciprocating motion along the master part. It moves up and down together along the shanghai-dong of the lap head part.

Hereinafter, the stretch film wrapping apparatus of the present invention will be described in detail with reference to the accompanying drawings.

3 is a plan view of a stretch film wrapping apparatus, in accordance with a preferred embodiment of the present invention.

Referring to FIG. 3, a lap head portion 22 attached to the master portion 21 and a cutting and sealing portion 23 attached to the lap head portion are included.

The wrap head portion 22 is a portion for wrapping the product by reciprocating up and down along the master portion 21. The wrap head portion 22 of the present invention is a wrap scratch head for stretching the wrap to reduce packaging costs and improve the binding force of the wrap. Wrap head portion 22 is attached to the mast portion as in the prior art to wrap (wrapp wrapping) the product located on the turntable while moving up and down.

The cutting and sealing portion 23 is not attached to the master portion 21, but is fixedly attached to the lap head portion 22 that can be reciprocated up and down unlike the prior art. Therefore, as the wrap head portion 22 moves up and down, it moves together.

The lap head portion 22 is connected to the cutting and sealing portion 23 by a cylinder 30, a rack gear 32, a pinion 34, and a shaft portion 36.

The rack gear 32 is moved left and right by driving the cylinder 30 provided in the lap head part 22. The pinion 34 rotates in response to the movement of the lag gear 32 while meshing with the lag gear 32. Since the shaft portion 36 is fixed to the pinion 34, the shaft portion 36 also rotates by the rotation of the pinion 34. As the shaft portion rotates, the entire cutting and sealing portion 23 rotates.

After the lapping process of the product by the wrap head, the cylinder is driven to cut and seal the cutting and sealing portion in the direction of the arrow to cut the wrap, sealing the end of the wrap.

Accordingly, the stretch film wrapping apparatus of the present invention does not perform one reciprocating movement from the bottom to the top and back to the bottom because the cutting and sealing parts are attached to the wrap head and move up and down with the movement of the wrap head. Without moving, it is possible to cut and cut the wrap directly from the top after moving from the bottom to the top. Accordingly, it is possible to reduce the packaging material (wrap) has excellent economic efficiency, there is an advantage that can reduce the packaging time.

 Of course, depending on the selection, the control box can be operated to cut and cut the lap after one reciprocation of the lap head. Accordingly, there is an advantage that the thickness of the wrap to be wrapped in the product can vary depending on the type or weight of the package.

After the lapping process of the product by the wrap head portion, the cutting and sealing portion is rotated to cut and seal the wrap.

The cutting and sealing parts are rotated to abut on the lap, and then the rod-shaped clamp bar 40 located at the top is rotated by the driving of the rotating cylinder 38 to be seated on the lower clamp bar seating part 41 (Fig. 4). Accordingly, the clamp bar 40 and the clamp bar seating portion 41 catch the wrap. The clamp bar 40 is preferably coated with leather so as not to scratch the wrap.

The wrap must be kept at a constant distance from the heating cutter 42 before it is cut. Since the heating cutter 42 has heat to cut the lap, the lap must be spaced apart before being cut. Guide bar 44 surrounding the heating cutter on both sides serves to protect the heating cutter while at the same time spacing the wrap so that the wrap does not adhere to the heating cutter.

After the lapping process is finished, the wrap is still wrapped in the product and the other end is connected to the wrap head, so the wrap is kept taut. The wrap is connected to the product 60 along the end of the guide bar 44.

After holding the lap using the clamp bar 40 in this state, the guide bar 44 is moved backward using the cylinder 46. Accordingly, the wrap is cut by the heating cutter 42. The heating cutter 42 has a Teflon coating to prevent foreign matter from being attached to the wrap.

After cutting the wrap with the heating cutter, the product is discharged out of the turntable along the discharge conveyor. Heater adhesive portion 50, which is a part of attaching the cut wrap to the product, the heater is built-in, the end is a brush form. That is, the sole primarily serves to sweep the end of the cut wrap, and secondly, the adhesive is treated by the heat of the heater so that the end of the wrap is firmly attached to the product. The movement of the heater bonding part 50 is made by the cylinder 48.

When the product is discharged, the wrap head portion 22 moves to the lower portion of the master portion 21 while the clamp bar 40 holds the wrap. When the lap head portion 22 moves to the lower end of the master portion 21, the clamp portion 26 formed on one side of the turn table is to hold the lap again. When the clamp portion 26 catches the wrap, the cutting and sealing portion 23 rotates halfway again to its original position.

In this state, the new product is placed on the turntable and the lapping process for the new product is started again. The clamp unit 26 continues to hold the wrap until the product turns around the turntable, and then the end of the wrap is released when the product turns once. At the same time the clamp unit 26 releases the wrap, the wind is blown through the blower located at the bottom of the clamp unit 26 toward the product. This is to prevent the end of the wrap from protruding out and pinching the drive device on the conveyor or the like. Continuously, the lapping process shown in FIG. 3 is performed by the rotation of the turntable.

The operation of the system of the present invention and the adjustment of each part are controlled by operation on the control box.

4 is a front view of a wrap head portion and a cutting and sealing portion of a wrapping apparatus according to a preferred embodiment of the present invention.

Referring to FIG. 4, the cutting and sealing portion 23 is attached to the wrap head portion 22. The dotted line mark of the cutting and sealing part 23 shows the clamp bar 40 being rotated halfway and seated on the seating part 41. Heater adhesive portion 50 can be seen that the end is formed in the form of a brush.

As described above, the stretch film wrapping apparatus of the present invention is a packaging device for preventing the adhesion of foreign matters, such as lightweight packaging or dust, is a device designed to enable the packaging only 1/2 stroke without the up and down reciprocating packaging. The packaging speed is twice as fast as the conventional packaging apparatus, and there is an advantage that the consumption of packaging materials can be reduced in half. When packing heavy materials, the packing speed can also be doubled since thick wraps than usual packaging can be used without reciprocating operation.

The foregoing has outlined rather broadly the features and technical advantages of the present invention in order to better understand the claims of the invention which will be described later. Additional features and advantages constituting the claims of the present invention will be described below. It should be appreciated by those skilled in the art that the conception and specific embodiments of the invention disclosed may be readily used as a basis for designing or modifying other structures for carrying out similar purposes to the invention.

In addition, the inventive concepts and embodiments disclosed herein may be used by those skilled in the art as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. In addition, such modifications or altered equivalent structures by those skilled in the art may be variously changed, substituted and changed without departing from the spirit or scope of the invention described in the claims.

As described above, in the present invention, since the cutting and sealing portions are attached to the lap head portion and move up and down with the movement of the lap head portion, the present invention does not necessarily cut the lap after the reciprocating movement of the lap head portion as before. Since the product can be wrapped in only one layer, the packaging material (wrap) can be reduced and the packaging time can be shortened.

According to the user's choice, the control box can be cut and cut after lapping one or two or more wraps by the operation of the control box, and there is an advantage that the thickness of the wrapped wrap can be varied according to the type or weight of the package.
