There has been provided a device that shrinks the material and tension-wrappes the object to be packaged. Such tension packaging has the advantage that the packaged items, such as fruits and vegetables, are less likely to be damaged during the distribution process, but heat-shrinkable films tend to harden due to heat shrinkage, and the volume of the packaged items also increases. Once the bag is opened, it is impossible to reseal the opened part, since the bag has been shrunk to its maximum extent in response to the above. Therefore, after dispensing a portion of the packaged items such as vegetables, the bag is unsuitable for storing the remaining vegetables in the same bag.

体を形成することができる。(Function) The bag-making device described above continuously pulls out the film supported on the shaft by a tension conveyor and forms it into a tube by a tube-making mechanism. Further, the objects to be packaged are successively fed into the tube by the supply means, and the objects to be packaged are arranged at equal intervals in the tube. Furthermore, a cutter having a heater element only on the rear side of the blade cuts and seals the tube between each packaged object to form bags with one end open one after another, and inserts each bag in a column at the end of the bag making device. Carry it out. A conveyor provided at the rear of the bag-making device receives bags one after another as they are carried out from the device, and acts to convert the conveyance direction of each bag into rows.
After wrapping a binding band around the mouth of each bag using a binding device provided in the middle of this conveyor, each bag is guided into a box equipped with a hot air device to heat-shrink the bag. In this case, since the opening of the bag is configured to protrude outside the box through the gap, the bag maintains its flexibility at the opening, and the binding band can be untied to form a package that can be opened and closed freely. can.

るので収縮しない。 In FIG. 1, when the heat-shrinkable film F supported in the form of a roll on the shaft 26 is pulled and unraveled by the tension conveyor 6, the film F is formed into a tube by the tube-making mechanism 5, and then sent to the cutter 7 to form a predetermined shape. cut to length. Since the cutter 7 is equipped with a heater element only on the rear side 9 of the blade 8, the bag is welded only at the rear side cut by the blade 8, that is, from the tube side, only the front end 27 of the tube is welded. A is mass-produced one after another. When the film F is formed into a tube by the tube-making mechanism 5, by sequentially supplying the objects to be packaged into the tube, the objects to be packaged are stored in each bag A, A... be done. Then, each bag A formed by the bag making apparatus 1 is transferred to the conveyor 2 at the rear thereof and receives the conveyance function of the conveyor 2. The conveyor 2 has the function of transporting each bag A laterally, but during the transport process, each bag A is subjected to the action of a binding device 3 as described below. That is, in FIG. 2, the upper chain 12 moves counterclockwise at a higher speed than the conveyor 2, and the lower chain 13 moves counterclockwise at a higher speed than the conveyor 2.
Because each rotates clockwise at a slower speed than the
two pieces 14 provided on both chains 12, 13;
In the process of moving from left to right in the drawing, 15 relatively approaches due to the speed difference and squeezes the opening of bag A slightly. A pair of cutters 18 and 19 provided near the rear ends of the chains 12 and 13 are connected to binding bands supported on the shafts 16 and 17, respectively, with pressure-sensitive adhesive tapes B and B, such as Sellotape (trademark). They are arranged so that they are sandwiched and rotated intermittently so that the two tapes B,
When it reaches between B, it rotates by a predetermined angle, cuts the tapes B, and stops. This result bag A
The opening is bound between the adhesive surfaces of two adhesive tapes B and B. After that, the bag A is transferred to the hot air device 4.
is carried into the box 21 from the entrance of the box 21.
Hot air circulates inside the box 21 through a duct 22, and therefore, as shown in FIG.
Since the upper part protrudes from the side hole 25, it does not shrink.
なお結束用帯Bとしては、例えば被覆金属線で
袋口を結束することも可能なので、結束装置3と
しては図示以外の公知の構造のものを使用しても
よいのは勿論である。 Note that as the binding band B, it is also possible to bind the bag opening with a coated metal wire, for example, and therefore, as the binding device 3, it is of course possible to use a device having a known structure other than that shown in the drawings.

ある。(Effects) As mentioned above, the present invention is constructed by installing a conveyor after the bag making device 1, and installing a binding device 3 and a hot air device 4 along the conveyor 2. Since a hole 25 is formed on the side surface to allow the opening of the bag A to protrude outside, the bag is heat-shrinked in the area below the binding band B, as shown in Figure 4, thereby preventing damage to the packaged items. In addition to being able to shrink-wrap without wrapping, the area above the binding band B retains its flexibility without being heat-treated and has a flexible lip, so it is possible to untie the binding band B and make a small part of the packaged item. After taking it out,
This has the effect of mass producing a packaged product in which the bag can be resealed as it is and the remaining packaged items can be stored.
