Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a skin knocking device that places a K11 item on a mount and strokes a film over it to seal it.

Generally, a skin knock device has a heating device 2 equipped with a heater above the machine base l, as shown in FIG. The film 3 is fed out one after another and is clamped by a square clamp frame 4 so as to knock the product placed on the work surface 5 of the machine base 1.

As shown in FIG. 2, the film 3 is lifted upward while being held between the Clive frame 4 consisting of an upper frame 4a and a lower frame 4b, approaches the heating device 2&C, is disposed inside the heating device 2, and is placed inside the heating device 2. Heated by E-Yu6, 6...6 [becomes flexible]. During this time, as shown in FIGS. 3 and 4, the mount 7 is placed on the work surface 5 within the A-key frame 8, and the products 9, 9, . . . is placed. K on top of this.

The heated film 3 is guided over the clamp frame 4 and then air is sucked through the vacuum surface 10 to create a vacuum inside the frame frame 8. Therefore, the film 3 clamps the product 9 onto the mount 7. Knock it snugly on top.

However, in such a conventional device, as shown in FIG.
When heating the film 3, a gap is created between the heating device 2 and the two clamp frames 4, so that the heat from the heater 6 can easily escape, and wind can enter the heating device 2 from all sides of the clamp frame 4 and prevent the film from heating. Not only did it take time to heat up, but it also consumed a lot of electricity.

In addition, when transporting a relatively heavy object, a support plate for transportation, which is a plywood board with holes, is placed under the mount 7 shown in Fig. 3.4, and the support plate is taken out after being packed. In this case, since the product to be loaded is heavy, the support plate should be moved to the A cuum frame 8.
If it is inserted inside, it is difficult to extract from the 79 cuum frame 8 after packing, so the support plate is placed on the vacuum frame 8 for vacuum packing. Therefore, the condition of the film 3 in the vicinity of the Paguième frame 8 was not as shown in FIG. 3.4, and the air shutter was insufficient, resulting in skin knock defects at times.

In view of these points, the present invention is capable of heating a film in a short time with less electric power, and even when using a support plate for transportation when knocking a relatively heavy product.
To provide a skin knocking device in which an air shutter in a five-knee frame is perfect and knocking defects do not occur.

Embodiments of the present invention will be described below with reference to FIGS. 5 to 7.

In FIGS. 5 and 7, the heating device 2 has a box-like casing opening at the bottom, and this casing (9
) rod-shaped heaters 6, 6...6 are horizontally suspended.

A mounting frame 4 having a square cross section is fitted onto the upper frame 4a of the square clamp frame 4, and a fixing screw B is attached to an appropriate position on the outer side wall of the mounting frame 4, and by adjusting the fixing screw B, The attachment frame 4 is attached to and detached from the upper frame 4m.

A vertical wall 21J& is integrally formed on the upper surface of the mounting frame (2), and a reflecting plate ρ is obliquely fixed to the upper part of the vertical wall 21m by a hinge h (FIG. 7) K. This reflective plate n is formed of something like an aluminum plate, and is attached to the four circumferences along the clamp frame 4, so that the clamp frame 4 holds the film 3 and approaches the heating device 2. When this happens, the upper part of the reflector plate n is shaped like a trap so that it is inserted into the casing of the heating device 2.

If the reflector plate n is provided so as to be inclined inward, the heat from the heater 6 will be reflected by the reflector plate 22 and will not leak to the outside of the casing, and the wind from the outside will also be blocked by the vertical wall 21aK. The film 3 is heated in a short time because it becomes difficult to enter the film 3.

Therefore, not only work efficiency is improved, but also power consumption is reduced.

In addition, the inner wall 21bK of the mounting frame 4 extends horizontally to the shelf 2.
1c protrudes, and a retainer-shaped presser device is fixed onto this shelf 21c with a fixing screw. This presser par 23
are arranged in a lattice shape within the flange frame 4, and the size of this lattice is set to suit the size of the product to be touched. Since the presser foot device is for pressing the film 3, the presser section 23 has an upper frame 4a and a lower frame 4b.
A heat-resistant cushioning material 3 is attached to the lower side of the shelf 218, and this heat-resistant cushioning material 5 is installed so as to be substantially flush with the joint surface with the shelf 218, as shown in FIGS. 6 and 7. When the clamp frame 4 is placed on the mounting frame 8, the film 3 is pressed around the four circumferences of the mount 7 to prevent outside air from entering when the clamp frame 4 is clamped.

A support plate 26C for transportation, which is a plywood board with holes for suction, is placed on the square frame 8, and the mount 7 is placed on the support plate 26C. Product 27 on this mount 7
, 27--The nails are positioned within the grid of the presser foot.

As shown in FIG. 5, the heated and softened film 3
When the product I is covered with the film 3
Made of! ! 127 on the mount 7, so the film 3
Improves adhesion to products. In this state, when the inside of the Paquième frame 8 is evacuated using a vacuum cleaner, the film 3 is adsorbed onto the product 4 and the mount 7, but at this time, the four circumferences of the film 3 are pressed by the heat-resistant cushion material 5, so the air When the shutter is completed, the unstable film portion 3a between the mount 7 and the clamp frame 4 is attracted to the side of the mount 70 during vacuuming, as shown by the chain line in the figure.
b The seal is complete.

A row of heaters is provided near the outer end of the joint surface of the clamp frame 4, and one side of the film 3 is cut by this heater. When the knocking is completed, the clamp frame 4 is removed and the product is released together with the support plate. It is removed from the vacuum frame 8 and transported to another location.

In this way, if the support plate is placed on the vacuum frame 8, what happens to the support plate? Unlike inserting it into the vacuum frame 8, it is easy to attach and detach it to the vacuum frame 8,
Especially when the product is heavy, the support plate 3 is moved to the vacuum frame 8.
It needs to be placed on top.

Furthermore, as shown in Fig. 5, when the film 3 is first heated, it once sags as shown by the dashed line 5, and as the heating continues, it shrinks and becomes temporarily taut, and eventually sag. Since the clamp frame 4 is lowered at the beginning of this slack, the film portion 3c located at the bottom of the reflective plate n
Heat can also be added to K.

Therefore, the heating range of the film does not become narrower by 50% due to the attachment of the reflector plate n.

As explained above, the present invention provides a reflection plate for reflecting the heat of the heating device on the clamp frame, and a cushion material for pressing the four circumferences of the film onto the mount when vacuuming the inside of the clamp frame. This makes it possible to heat the film in a short time and with less electricity, and when knocking a relatively heavy product, a supporting plate can be provided on the underside of the mount for transporting the product. The shutter is perfect and knocking defects do not occur.Furthermore, by providing a presser on the clamp frame, the film adheres to the product more completely and the distance between the products can be reduced, resulting in a reduction in the amount of packaging film used. play.
