Definitions

  • the present invention relates to a method and apparatus for manufacturing paper cushioning members, and more particularly, to a method and apparatus for cutting a single sheet or plural sheets of work paper to be processed, such as unused paper or old paper like advertisement paper inserted in newspaper or the like, old newspaper, used copying paper, paper printed by an OA (Office Automation) equipment or used corrugated cardboard, to plural rows of thin intermittently-cut bands, forcibly putting the cuts-made work paper through a narrow passage to make the whole thin bands wavy and finely crumpling the thin bands unit by unit, so that the work paper can be used directly without any other processing as various cushions or packings for transporting objects and even work paper to be processed larger than the specified size can be processed with a predetermined width while the unnecessary portions are cut away.
  • work paper to be processed such as unused paper or old paper like advertisement paper inserted in newspaper or the like, old newspaper, used copying paper, paper printed by an OA (Office Automation) equipment or used corrugated cardboard
  • Another known cushion is a strong kraft paper processed to have short cuts and link portions by press working and then stretched to yield a fine almost beehive-like net.
  • the first type namely balls made of newspaper
  • the second type are soft to serve as good cushions, they are independent piece by piece and are easy to scatter, resulting in a lower working efficiency.
  • it is difficult to use the torn and crumpled pieces of paper directly they are normally placed in a paper bag or a poly bag when in use. If the bag is torn or broken, however, the crumpled pieces of paper undesirably come out of the bag through the torn section.
  • the material should be a thin sheet of paper and the net should be formed sheet by sheet.
  • Work paper to be processed larger than the specified size cannot be processed by processing rollers, so that such work paper should be cut by a separate cutter every time it is to be processed.
  • a method of manufacturing paper cushioning members which comprises the steps of inserting a sheet or sheets of work paper between a pair of intermittent cutting roller members (1, 2) to provide multiple rows of thin bands with link portions (7 1 -7 n ); causing processed paper to be put in cutaway portions (6) each formed in a part of projections (4) of the roller members (1, 2) to form creases; causing claws of waste-collecting members (17), provided on a discharge side, to scrape the processed paper off the cutaway portions and feeding the processed paper to a wave-forming guide (16) while forming crumples; forcibly putting the processed paper through the wave-forming guide (16) to make fine crumples on each unit of thin bands; and discharging the processed paper while the thin bands are entirely made wavy.
  • an apparatus for manufacturing paper cushioning members which comprises a pair of elongated roller members (1, 2) having circumferential recesses (3) and projections (4) each of a given width formed thereon and therearound; cutting blades (1', 2') formed at peripheral edges of surfaces (R) of the circumferential projections (4) of the roller members (1, 2); cutaway portions (6) each formed in a part of a circumferential surface of each of the projections (4) along an entire width (W) of that projection (4), work paper (P) being put into the cutaway portions (6), the recesses (3) and projections (4) of one of the roller members (1, 2) being engaged with the projections (4) and recesses (3) of the other roller member respectively; an upper pressing member (16 1 ) and a lower receiving member (16 2 ) arranged on a discharge side of the roller members (1, 2); a wave-forming guide (16) with a passage (5) having a height (h) about half of a circumferential length of the roller
  • reference numerals "1" and “2” denote a pair of elongated steel roller members whose shaft portions 1 1 and 2 1 at both ends supported on a frame F by means of bearings.
  • Reference numerals "3" and “4" respectively denote rectangular, circumferential recesses and projections with a given width (allowed to be about 3 to 5 mm), which are formed on each of the roller members 1 and 2 that have diameters of 42 mm.
  • the circumferential recesses 3 of one roller member engage with the circumferential projections 4 of the other roller member, while the circumferential projections 4 of the former roller member engage with the circumferential recesses 3 of the latter roller member.
  • Cutting blades 1' and 2' are formed at the peripheral edges of the circumferential surfaces R of the circumferential projections formed on the roller members 1 and 2.
  • Each projection 4 of each roller member has cutaway portions 6 each formed in a part of its circumferential surface in the width direction w of that projection.
  • the circumferential length of each projection 4 and the length G of each cutaway portion 6 can be set arbitrarily.
  • the diameter of the projections is 42 mm
  • the entire circumferential length of the projections is set to about 132 mm
  • the recesses 3 and projections 4 are to be engaged in such a way that the lengths of one unit of cuts respectively become about 99 mm and 33 mm
  • the length G of a single cutaway portion 6 of each projection is set to about 6 mm.
  • Fig. 1 illustrates the cutaway portions 6 formed in and across the circumferential projections 4.
  • Reference numeral “7” denotes cuts formed in work paper P at a given width W (about 5 mm in the illustrated example) by the pair of roller members 1 and 2.
  • Reference numerals “7 1 ,” “7 2 ,” “7 3 ,” ... “7 n” denote link portions which link the associated cuts 7 together.
  • the cuts 7 and the link portions 7 1 to 7 n are set by the intermittent recesses of the circumferential recesses 3 and projections 4 of the roller members 1 and 2 and the lengths between the intermittent recesses. In the example of Fig.
  • Reference numerals "8" and “9” are gears, which are attached to the shafts 1 1 and 2 1 of the roller members 1 and 2 and are engaged with each other to transmit power. Power from a motor (not shown) is transmitted to one of the gears, 8, through a belt or a chain.
  • Reference numeral “16” is a wave-forming guide for processed work paper, which is located on the discharge side of the elongated steel roller members 1 and 2 in the lead-in direction thereof.
  • the wave-forming guide 16 comprises an upper pressing member 16 1 and a lower receiving member 16 2 , and defines waste-collecting members 17, which have claws and recesses formed on the roller-member side edge portions thereof that match with the recesses and projections of the roller members 1 and 2.
  • Formed in the wave-forming guide 16 is a passage 5 of a predetermined height h which has a certain relation with the circumferential length of the roller members 1 and 2.
  • one unit cut length L'' is set to 99 mm
  • the other unit cut length L' is set to 33 mm
  • the lengths G of the cutaway portions 6 are set to 6 mm
  • the height h of the passage 5 of the wave-forming guide 16 is set to about 33 mm.
  • the upper pressing member 16 1 has its base attached to be rotatable by a hinge 19, with a weight 18 provided at the outlet portion of the upper pressing member 16 1 .
  • the passage 5 is narrowed by the distal end portion of the upper pressing member 16 1 .
  • the paper moves against the weight 18 while being compressed by the narrowed passage 5, gradually widening the passage 5, and is discharged while forming waves a having the height h of that passage 5, and those portions of the processed paper in the recesses 3 are scraped off by claws 17 1 and 17 1 ' of the waste-collecting members 17, thus forming crumples b.
  • the recesses and projections of the roller members 1 and 2 form waves (i.e., when the paper on the lower roller member side waves upward, the adjacent portion of the paper on the upper roller member side waves downward), and each unit of thin bands are fitted in the recesses 3.
  • those thin bands are scraped off by the waste-collecting members 17, those portions fitted in the cutaway portions 6 are also scraped off, thus forming creases c.
  • Reference numeral "20" denotes a casing for covering the roller members 1 and 2.
  • the casing 20 receives the outer-positioned shafts 2 1 ' and 2 2 ' of the roller members 1 and 2.
  • Formed in the shaft-receiving portion of the casing 20 is an opening 21 through which work paper to be processed can pass.
  • Reference numerals "23" and “24” denote projections which are formed, without the cutaway portions 6, on the lengthwise outer periphery portions of the recesses 3 and projections 4 of the roller members 1 and 2.
  • Reference numeral “25” is a reinforcement member provided on the work-paper discharge side of the opening-side casing.
  • the reinforcement member 25 stabilizes the mouth portion of a cantilever type opening 21.
  • the cutting blades 1' and 2' of a given width are formed on the roller member pair 1 and 2, the cutaway portions 6 are formed in the circumferential surface R of each projection 4 in the same direction, and the recesses 3 and projections 4 of one roller member are engaged with the projections 4 and recesses 3 of the other roller member respectively.
  • the waves a are formed and the crumples b are formed on the waves.
  • the processed paper is also inserted in the wave-forming guide 16 continuous to the waste-collecting members 17.
  • the processed paper in the recesses 3 of the lower roller member 1 when separated by the claw 17 1 of the lower waste-collecting member 17, moves upward while forming crumples
  • the processed paper in the recesses 3 of the upper roller member 2 when separated by the claw 17 1 ' of the upper waste-collecting member 17, moves downward while forming crumples.
  • the paper moves toward the front of the guide passage 5 that is narrowed by the weight 18 at the distal end of the upper pressing member 16 1 , it is compressed, forming the entire thin bands into waves a in the guide passage 5 within the height h and making fine crumples b of each unit of thin bands.
  • the upper pressing member 16 1 moves upward via the hinge 19 against the weight 18, the paper is discharged from the outlet of the wave-forming guide 16 while stretching the passage 5 (see Fig. 7).
  • the cuts 7 and link portions 7 1 , 7 2 , ..., 7 n are alternately formed on the processed paper P by the roller members 1 and 2 along the cutting blades 1', so that three two of cuts 7 and two link portions 7 1 and 7 1 , 7 2 and 7 2 , ..., 7 n and 7 n are formed for three rows of thin bands 11, 12 and 13.
  • a net 7' of the size as shown in Fig. 6 is formed.
  • the creases c are formed by the cutaway portions 6 on the processed paper, fitted in the cutaway portions 6 across the thin bands that form the net, and the waves a are formed with the fine crumples b on the processed paper by the wave-forming guide 16.
  • the reinforcement member 25 is provided on the work-paper discharge side of the casing 20. Because the unnecessary portions of the work paper are cut by the projections 23 and 24, which have no cutaway portions and are located on the lengthwise outer periphery portions of roller members 1 and 2, before reaching this reinforcement member 25, however, the processed paper P and the unnecessary portions thereof do not hit against the reinforcement member 25 so that the reinforcement member 25 does not interfere with the discharge of the processed paper.
  • the thin bands located in the recesses in the roller members tend to stick around the roller members without the waste-collecting members which having claws. According to this invention, however, fine crumples can be formed while separating the thin bands by means of the waste-collecting members. It is therefore possible to form relatively large waves on processed paper and form fine crumples on the wavy thin bands to thereby provide softer cushioning members accompanied with a larger amount of air.
  • the processed paper with intermittent cuts when the processed paper with intermittent cuts is put through the wave-forming guide to make the entire thin bands wavy and finely crumple each unit of thin bands, the processed paper can have a significant height in the direction of the thickness of the paper.
  • the resultant paper even without being processed any further, can serve as effective cushioning members.
