Definitions

  • the present invention relates to a printing media pile board on which the printing media such as printing paper fed to a sheet-fed type printing press are piled up; particularly relates to a pile board for a printing press suitable for a non-stop-type feeder feeding printing media non-stop to a sheet-fed type printing press.
  • a sheet-fed type printing press which prints on each of printing media such as printing paper, ledger paper and films, it is required to feed one sheet each of printing media sequentially to the printing press.
  • the printing media fed to the sheet-fed type printing press are piled up on a piling platform called a pile board, and fed to the printing press by a feeder one sheet each (e.g. Japanese Unexamined Patent Publication H6-135578 ).
  • the board used for piling up printing media in the non-stop-type feeder is in general a platform formed in a flat plate shape with forming grooves, to insert a comb-like supporting portion of a fork for supporting the printing media, on a surface for piling printing media, for example.
  • a weight of the printing media are fairly large.
  • fairly heavy printing media are desired to be piled up on the board for feeding to the sheet-fed type printing press.
  • the board is formed with wood such as plywood to endure the weight of the printing media piled thereon.
  • the conventional pile board is formed with wood
  • the comb-like supporting portion, or a wheeled platform and a conveyer delivering the pile board repeatedly contact, slide or collide against the pile board, resulting in wood waste from the wood, a base material of the pile board. If the wood waste is delivered to the inside of the printing press via the printing media piled up on the pile board, it may enter a transferring portion wherein an ink is transferred to the printing media, and cause a defect in printing. In this case, a problem arises that productivity is reduced due to cleaning the printing press to remove this wood waste.
  • the above problem may be overcome by forming the entire pile board with metal, but it is impractical since the metallic pile board is fairly heavy, which results in difficulties in handling by an operator or processing in a feeder of a sheet-fed type printing press.
  • the present invention reflecting this situation, has a purpose to provide a pile board for a printing press, waste-free and easy to handle.
  • a pile board for a printing press on which printing media fed to the printing press are piled up, comprising a base formed with a resin having a piling face on which said printing media are piled up, and grooves formed on said piling face allowing insertion of a supporting member to support said printing media and there being a metallic reinforcing member provided in said base.
  • said metallic reinforcing member is two or more metallic rod-shaped members.
  • said metallic rod-shaped members are arranged so as to set its longitudinal direction in the direction perpendicular to the grooves formed on said base.
  • said metallic rod-shaped members are bearing bars formed to have a hollow shape.
  • said metallic reinforcing member is fixed in an opposite face to the piling face in which said printing media are piled up.
  • the present printing press is a printing press using a pile board for a printing press comprising a base formed with a resin having a piling face on which printing media fed to the printing press is piled up, and grooves formed on said piling face and insertable of a supporting member to support said printing media, and a metallic reinforcing member provided in said base.
  • a pile board for a printing press not generating waste from the pile board and easy to handle.
  • a sheet pile board, the pile board for a printing press of the present embodiment, is a member on which printing media such as large-sized paper and films fed to a large-scale sheet-fed type printing press are piled up.
  • this is a sheet pile board suitable for a non-stop-type feeder providing the printing media sequentially and continuously to the printing press without interrupting printing due to a lack of printing media.
  • FIG. 1 is a perspective view of a sheet pile board 1 of the present embodiment
  • FIG. 2A is a side view of the sheet pile board 1 from a direction A of FIG. 1
  • FIG. 2B is a side view of the sheet pile board 1 from a direction B of FIG. 1
  • FIG. 3 is a partial cross-sectional view of the sheet pile board 1 obtained by enlarging a portion C of FIG. 2B .
  • the sheet pile board 1 comprises a base 10 and metallic pipes 20.
  • the base 10 is, as shown in FIG. 1 , a rectangle in plane shape, and a flat plate-shaped platform as a whole, on which printing media are piled up to be fed.
  • the plane shape and plane size of the base 10 may depend on the size of the printing media and specification of a transfer system of a sheet feeder of the sheet-fed type printing press; and normally, the shape is often rectangular as shown in FIG. 1 .
  • the grooves 11 are grooves for inserting a comb-like (rod-like) supporting portion (specifically, for example, an ironcore such as a square pipe) of a fork to support printing media piled up on the base 10 (sheet pile board 1) when decreasing the printing media piled up on the base 10 to a predetermined quantity.
  • a comb-like (rod-like) supporting portion specifically, for example, an ironcore such as a square pipe
  • the base 10 sheet pile board 1
  • the comb-like supporting portion of the fork is inserted into the grooves 11 of the base 10.
  • the base 10 is removed from the sheet feeder, and a new base 10 with a full of printing media is placed below the comb-like supporting portion of the fork which supports the printing media.
  • the arrangement and shape of the grooves 11 formed on the upper face 12 of the base 10 may be determined based on those of the comb-like supporting portion (concretely, an iron core) of an apparatus such as the above mentioned fork for piling up the printing media and taking the printing media out.
  • the base 10 is formed with a norbornene-based resin and has a smooth surface, which does not cause waste even when the comb-like supporting portion of the fork, a wheeled platform and conveyer delivering the board, and the like repeatedly contact, slide or collide against the board. Therefore, no waste is carried into the printing press by the printing media, so that productivity is improved without failure in printing. Also, due to forming the base 10 with resin, the base itself can be reduced in weight and in production cost.
  • an opposite face of the piling face 12 of the sheet pile board 1 four metallic (e.g. stainless-steel) pipes (hollow pipes) 20 (bearing bars) having a circular cross section are fixed as the metallic reinforcing member.
  • metallic circular pipes 20 are respectively placed at approximately even intervals with its axial direction facing to a direction perpendicular to that of the grooves 11.
  • a concave portion 13 with an approximate size able to contain at least the metallic circular pipes 20, are formed as shown in FIG. 2A and FIG. 2B .
  • Four metallic circular pipes 20 are contained in the concave portion, and fixed to the rear face of the sheet pile board 1 at both ends by a screw 30 as shown in FIG. 3 .
  • a first hole 21 and a second hole 22 are formed respectively.
  • the first hole 21 is a large opening that the screw 30 can pass through in whole including its head
  • the second hole 22 is a small opening enough for only the thread portion (axial portion) of the screw 30 to pass through.
  • These first hole 21 and second hole 22 are formed in a same direction in several spots of the metallic pipe 20.
  • the screw 30 is moved from the first hole 21 to the inside of the metallic pipe 20; the thread portion of the screw 30 is projected from the second hole 22 to screw into the rear face of the base 10 to fix; and the metallic pipe 20 is pressed to fix to the rear face of the base 10 by the head of the screw 30, so that the metallic pipe 20 can be fixed in the rear face of the base 10.
  • the sheet pile board 1 When applying the sheet pile board 1 having such a constitution to a non-stop-type sheet feeder of a sheet-fed type printing press for printing on one sheet each of large-sized printing media, the sheet pile board 1 is required to sequentially support a large quantity of, i.e. heavy, printing media.
  • the base 10 In the sheet pile board 1 of the present embodiment, the base 10 is lowered in its own strength compared with a wooden base, since the base 10 is formed with resin.
  • the sheet pile board 1 is, however, significantly strengthened, since four metallic pipes 20 are buried in the rear face. Therefore, even when feeding a large quantity of heavy printing media, the sheet pile board 1 is properly piled with the printing media and supports them without bending.
  • the sheet pile board 1 on which the printing media are piled up is put in a printing system including the printing press, by a transfer system such as a conveyer of the sheet feeder of the sheet-fed type printing press. In this step, rigidity of the sheet pile board 1 is properly maintained as well, so that the printing media are properly piled up on the sheet pile board 1 and fed to the printing press with a suitable posture without bending or heaving.
  • the comb-like supporting portion of the fork is inserted into the grooves 11 of the base 10, and by moving downward of the base 10 or moving upward of the comb-like supporting portion of the fork, the printing media piled up on the base 10 are supported by the comb-like supporting portion of the fork. Then, the base 10 is removed from the sheet feeder, and a new base 10 with a full of another printing media is placed below the comb-like supporting portion of the fork supporting the printing media.
  • the sheet pile board 1 of the present embodiment although the base 10 is formed with resin, the strength is significantly increased due to four metallic pipes 20 buried in the rear face of the base 10, and even if fairly heavy printing media are piled up on the sheet pile board 1, the sheet pile board 1 can always and precisely feed the printing media without bending to the printing system.
  • the use of the hollow metallic pipe 20 can result in not only increasing strength of the sheet pile board 1 but also reducing the weight of the sheet pile board 1, so that the sheet pile board 1 becomes easy to handle.
  • the base 10 of the sheet pile board 1 by forming the base 10 of the sheet pile board 1 with resin, it is possible to prevent a generation of waste, etc., from the sheet pile board 1. Consequently, it is possible to prevent a generation of defect in printing caused by such a waste, etc., so that the sheet pile board 1 can be used with high performance for a long time.
  • the pile board for a printing press of the present invention is not limited to the above-mentioned embodiment, and may be variously modified.
  • the metallic pipe is arranged with its axial direction facing to a direction perpendicular to the grooves of the sheet pile board, but any arrangement may be fine.
  • the axial direction of the metallic pipe 20b may be arranged in parallel with the grooves 11 of the sheet pile board 1b.
  • the metallic pipe placed in the rear face of the sheet pile board is not necessarily a circular pipe, and may be a square pipe 40 as shown in FIG. 5 .
  • circular pipe or square pipe is not limited to a hollow pipe, and a solid-core rod may be used in either case.
  • the metallic rod-shaped member is shown as a non-limited example of the metallic reinforcing member, and a metallic plate-like member may be fixed to the rear face of the base 10.
  • the constitution is exemplified that the metallic reinforcing member is fixed to the rear face of the base 10, but the resin base 10 may be moulded to embed or to integrate the metallic reinforcing member therein.
  • the number of the metallic pipes placed to the rear face of the sheet pile board is four in the example shown in FIG. 1 and two in the example shown in FIG. 4 , but it is not limited to those in the examples and may be three, or five or more.
  • each pipe may be arranged in parallel, or some or all of the pipes may be arranged at angle to each other.
  • the position in the rear face of the base wherein the pipes are placed may be arbitrary as well.
  • FIG. 6 is an entire external view showing a frame format of the constitution of a sheet-fed type printing press using the pile board for a printing press.
  • the sheet-fed type printing press 100 is generally comprised of a sheet feeding portion 102, a printing portion 103 and a sheet ejection portion 104.
  • the sheet pile board 1 on which the sheets 6 are piled up as printing media is arranged.
  • the sheet pile board 1 is mounted on a sheet stacking platform (not shown in the figure) which is hung by a hoisting chain (not shown in the figure) and automatically elevated as the sheets 6 are fed to the printing portion 103 to decrease the quantity of the sheets 6 on the sheet pile board 1, so that it has a constitution to maintain the upper face of the piled sheets at a certain height.
  • a guide rail 114 is horizontally built, and a fork platform 115 is movable in a horizontal direction in the figure, i.e. in the direction that it approaches or leaves the sheet pile board 1, on the guide rail 114 by a motor not shown in the figure as a drive source.
  • a plurality of forks 116 are provided in a protruding condition as a supporting member with an identical pitch to those of the grooves 11 on the upper face of the sheet pile board 1.
  • a successive sheet pile board (spare sheet pile board) 2 on which sheets 7 to be fed next as printing media are piled up, is arranged movably by a lorry 119.
  • the fork platform 115 is moved leftward in FIG. 6 to insert the fork 116 into the grooves 11 of the sheet pile board 1.
  • the sheet pile board 1 is lowered to support the sheets 6 in the upper face of the fork 116.
  • the spare sheet pile board 2 is moved by the lorry 119 so that the spare sheets 7 are positioned below the sheets 6, and the spare sheet pile board 2 is elevated so as to put the upper face of the spare sheets 7 toward the undersurface of the fork 116.
  • the fork 116 is extracted to put the sheets 6 on the spare sheets 7, which enables continuous sheet feeding without stopping the press.
  • a coloured sheet 8 which is an easy-to detect sheet with a different colour from that of the sheets 7, is piled.
  • One sheet each from top of thus-fed sheets 6 is suckomed by a sucking device not shown in the figure; sent onto a feeder board 122; then sent to a register device 124 of a register portion 123 to adjust a width direction register and a vertical register; and sent to the printing portion 103.
