Description

  The present invention not only fills the work sheet with a sufficient amount of fluid to increase the pressure, but also facilitates fluid flow from each fluid chamber that forms a completed cushioning material by filling the work sheet with the fluid. In addition to the cushioning material manufacturing apparatus that can prevent it from coming off, it also relates to a multi-processed sheet material that can easily complete a bag-shaped cushioning material that can store an object to be stored between processed sheets. It is suitable for manufacturing a cushioning material for protecting from impact.

  Various types of cushioning materials for packing are known, depending on the shape of the target article, etc., but they are highly versatile without being restricted by the product shape, and have an extremely high impact cushioning effect. An air chamber cushioning material having a large number of cylindrical air chambers in which etc. are enclosed is particularly frequently used.

  This air chamber cushioning material is also called an air cap (registered trademark) or bubble wrap (registered trademark), and has an advantage that an inexpensive polyethylene film can be easily and inexpensively manufactured. However, this type of air chamber cushioning material is very bulky because the air chamber is prefilled with gas in the manufacturing stage. Therefore, a large space is occupied for storage and transportation from the manufacturing factory to the store. For this reason, although it is made disposable for article protection, there is a disadvantage that the space cost is extremely bad.

  Therefore, in view of this problem, a shock absorber manufacturing device for enclosing air at a high speed in a case-like single bag sheet of shock absorber has been commercially available, and this shock absorber manufacturing device buffers air at the work site. It was used to fill the material.

  However, in such a work site, the processed sheet that has been pre-processed is filled with air while being conveyed to the cushioning material manufacturing apparatus at a high speed, so that the processed sheet is not sufficiently filled with air. There was a drawback in that the number of low pressures increased. On the other hand, the conventional shock absorber manufacturing apparatus, for example, integrally fills the horizontal row of spaces with air, so that if there is a flaw in any of the rows, there is a disadvantage that the air will escape from the entire row. It was.

  In addition to this, the demand for producing a cushion-like cushioning material capable of accommodating the article to be stored with this cushioning material manufacturing apparatus has increased in recent years, and the processed sheet subjected to pretreatment has a double structure.

  As a result, as the injection cylinder 12 advances in the passage 6 by the conveyance of the processing sheet 2 by the rotation of the conveyance rollers 26A to 26D shown in FIGS. The fluid blown out from the nozzle hole 14 </ b> A not only flows into the fluid sealing portion 5 from the passage portion 6 through the air introduction portion 7, but thereafter, the processed sheet 2 is further conveyed, thereby The fluid blown out from the secondary nozzle hole 16 </ b> A on the base end side further flows into the fluid sealing portion 5 from the passage portion 6 through the air introducing portion 7, thereby increasing the fluid pressure in the fluid sealing portion 5.

  Furthermore, immediately after this, a welding line 30 which is a welding member constituted by a fluororesin heating tape 34 which is formed in a ring shape and can be rotated and a metal hot plate 32 arranged on the back side of the heating tape 34, The processed sheet 2 is heated via the heating tape 34 to partially fuse the processed sheet 2. As a result, the fluid sealing portion 5 is sealed and partitioned into a plurality of parts, whereby air chambers 5B, which are fluid chambers in which fluids are individually sealed, are formed in the processed sheet 2, respectively. . Then, the rotary cutter 24 cuts the partition wall 6 </ b> A forming the passage portion 6 of the processed sheet 2 at the base end portion of the injection cylinder 12, so that the injection cylinder 12 can be detached from the processed sheet 2.

  From the above, according to the shock absorber manufacturing apparatus 10 according to the present embodiment, not only can the fluid filled portion 5 of the processed sheet 2 be sufficiently filled with air to increase the pressure, but also the individually independent air chambers 5B. Is formed on the processed sheet 2, and a cushioning material that makes it difficult for the fluid sealed in the air chamber 5 </ b> B to come out as a whole can be easily manufactured.

  On the other hand, in the shock absorber manufacturing apparatus 10 according to the present embodiment, not only the pressure sensor 20 that detects the fluid pressure in the passage portion 6 around the injection cylinder 12 is provided at the distal end portion of the injection cylinder 12, As described above, the outer pipe 22 having a larger diameter from the distal end side to the proximal end side of the injection cylinder 12 is provided at the proximal end portion of the injection cylinder 12 and rotates to a position facing the outer pipe 22. Conveying rollers 26A to 26D are provided.

  That is, according to the present embodiment, the fluid pressure around the injection cylinder 12 can be detected by the pressure sensor 20, so that sufficient air can be introduced into the fluid sealing portion 5 of the processed sheet 2 due to some trouble. When the pressure becomes insufficient because the filling cannot be performed, the operation of the entire cushioning material manufacturing apparatus 10 can be stopped by the control of the controller 28.

  Therefore, if the atmospheric pressure in the passage portion 6 does not reach a predetermined constant value, the operation of the cushioning material manufacturing apparatus 10 due to insufficient air pressure can be prevented by the control of the controller 28. If all the parts of the cushioning material manufacturing apparatus 10 are activated only when the atmospheric pressure in 6 reaches a certain pressure, the processed sheet 2 is conveyed at high speed in a state of insufficient pressure, resulting in a defective product. Can be prevented from being produced in large quantities.

  On the other hand, an outer pipe 22 whose diameter increases from the distal end side to the proximal end side of the injection cylinder 12 is provided at the proximal end portion of the injection cylinder 12, and a conveying roller corresponding to the outer pipe 22 By having 26 </ b> A to 26 </ b> D, the partition wall 6 </ b> A that forms the passage portion 6 hits the outer pipe 22 and is in close contact with the outer pipe 22.

  Then, as the processed sheet 2 is conveyed while being pressed by the outer pipe 22 by the conveying rollers 26A to 26D, a part of the partition wall 6A that forms the passage portion 6 of the processed sheet 2 in the outer pipe 22 portion. The portion is continuously cut by the rotary cutter 24, and the injection tube 12 can be detached from the processed sheet 2.

  That is, as the processed sheet 2 is conveyed at a high speed and cut by the rotary cutter 24, air is most easily released from the portion of the processed sheet 2 that hits the rotary cutter 24. It was decided to provide the formed outer pipe 22. Accordingly, the partition wall 6A of the passage portion 6 contacts the outer pipe 22 and the partition wall 6A of the passage portion 6 is pressed against the outer pipe 22 by pressing the partition wall 6A of the passage portion 6 against the outer pipe 22 by the transport rollers 26A to 26D. It will be in close contact.

  For this reason, as the gap between the injection cylinder 12 and the work sheet 2 becomes smaller in the outer pipe 22, the outflow of air from the gap between them can be prevented, and the air pressure around the injection cylinder 12 can be prevented. It is possible to prevent the decrease of the pressure and maintain the atmospheric pressure. As a result, the effect of preventing the production of a large amount of a buffer material in a low pressure state that becomes a defective product is more reliably exhibited.

  On the other hand, in the present embodiment, a welding line 30 which is a welding member is formed by a fluororesin heating tape 34 which is formed in a ring shape and can be rotated, and a metal hot plate 32 disposed on the back side of the heating tape 34. The sheet 2 to be processed is heated via the heating tape 34.

  That is, according to the present embodiment, the spaces 5A arranged along the lateral direction Y of the processed sheet 2 processed in the primary process conveyed at high speed are connected to each other. By heating the work sheet 2 via 34, the vertical wall portion 3 is minimized while rubbing between the heating tape 34 and the work sheet 2 and opening a hole in the work sheet 2. The gap S and the air introduction part 7 are welded by the four welding lines 30 to independently become the continuous air chamber 5B, so that the fluid sealing part 5 of the processed sheet 2 is reliably sealed and Divided into multiple sections.

  As a result, even if one air chamber 5B is damaged due to high-speed processing, a plurality of air chambers 5B in which air is individually enclosed inside are formed in the work sheet 2. If the adjacent air chamber 5B is intact, the safety as the packing material and the role of the cushioning material can be maintained, so that necessary functions can be secured.

  In addition, if the space | interval of the four welding lines 30 of this Embodiment is changed into arbitrary magnitude | sizes, the magnitude | size of the air chamber 5B can be changed. Along with this, if the welding line 30 is excessive, the number of necessary lines can be arbitrarily selected by moving the excess welding line 30 to the outside of the cushioning material manufacturing apparatus 10 to cope with it. . Further, in the present embodiment, the cutter for cutting the partition wall 6A forming the passage portion 6 of the processed sheet 2 is a rotary rotary cutter 24 instead of the fixed blade.

  In other words, if the rotary cutter 24 is employed, the fixed blade will not be cut quickly because it is a single location, while the rotary blade will rotate 360 ° and there will be a 360 ° location where it will hit the films 1A and 1B. This is because the blade life is long and the number of blade replacements is extremely small.

Next, a second embodiment of the cushioning material manufacturing apparatus according to the present invention is shown in FIG. 7, and the present embodiment will be described based on this drawing. Note that the same members as those described in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.
In the present embodiment, the position of the position where the processed sheet 2 is welded is the same as in the first embodiment, but instead of the heating tape 34 and the pressing tape 40 made of fluororesin, each is formed of a metal piece. In addition, there are four welding lines 50 in the form of a pair of crawler crawler portions 53 that are belt-shaped by connecting ends of a plurality of metal hot plates 52 to each other.

  The surface of each of the metal hot plates 52 facing the processed sheet 2 is subjected to a special surface treatment using a fluororesin, and the metal hot plates 52 connected in a belt shape by a crawler method. A heater 54 that is a heat source for temperature control of the metal hot plate 52 is installed on the inner peripheral side. Further, a belt type cleaner 56 for removing dirt adhering to the surface of the metal hot plate 52 is arranged on the upper side in FIG. However, the cleaner 56 moves like a dotted line.

  In the present embodiment, the processed sheet 2 is conveyed while the processed sheet 2 is sandwiched between the metal hot plates 52 of the crawler unit 53. Accordingly, since the processed sheet 2 remains sandwiched, heat is continuously applied to the processed sheet 2 while the processed sheet 2 is sandwiched, so that necessary portions of the processed sheet 2 can be completely welded even at a lower temperature.

  The shock absorbing material manufacturing apparatus 10 that manufactures the shock absorbing material by conveying the work sheet 2 at a high speed tends to cause the air pressure of the shock absorbing material to be relatively low, whereas the metal hot plate 52 connected to the crawler portion 53 is mutually connected. If the sheet to be processed 2 is conveyed at a high speed, as in the first embodiment, an amount of air pressure required as a packing material can be reliably secured. Further, as in the present embodiment, not only is the structure not using the fluororesin heating tape 34 by using the metal hot plate 52 in which the metal material is specially processed, but the cleaner 56 is provided in the upper part. As a result, the maintenance of the apparatus is extremely simple and easy to maintain.

  On the other hand, also in this embodiment, the size of the air chamber can be changed by moving the welding line 50 serving as a welding member. As a result, if the welding line 50 is excessive, the number of necessary lines can be arbitrarily selected by moving the excess welding line 50 to the outside of the cushioning material manufacturing apparatus 10. .
