Definitions

  • the present invention relates to a conveyor system for carrying planar objects by way of a conveyor belt and the like.
  • Corrugated cardboard boxes have been designed with a variety of sizes, shapes and in a variety of multicolor printings these days, and in coping with such designs, there have been presented a variety of functions of the machine for manufacturing the corrugated cardboard boxes, accordingly. Now, referring to the conventional construction of the corrugated cardboard box manufacturing machine with reference to FIGS.
  • a blank board supply station 1 a first printing machine 2, a second printing machine 3, printing cylinders 4, a transfer conveyor 5, a rotary die cutting station 6, a anvil cylinder 7, a die-cut cylinder 8, a die element 9, a board delivery conveyor (a scrap conveyor; a conveyor for a planar object) 10, a sheet of corrugated board 11, a died board 11' (through the single-cutting process), a died board 11" (through the double-cutting process), a stacker-conveyor 12, a counter-stacker 13, a board stopper 14, a spacing 16, a lifter 17, and a counting photoelectric tube 18, wherein a sheet of corrugated cardboard 11 is fed for printing by the board supply station 1 with such a rate of delivery of a sheet per single rotation of the printing cylinders 4 in the printing machines 2, 3, thereafter is delivered outwardly by the transfer conveyor 5 for having the printing ink put in the surface of a carboard 11 dried up, and then is died to a shape of cardboard box by way
  • the die element 9 comprises a cutting knife edge or the like implanted around the circumferential surface of a curved veneer board of a specified thickness, which is to be mounted onto the die-cut cylinder 8 by using bolts, and is adapted to cut and die a sheet of carboard 11 to be fed from the foregoing step into the nip with the anvil cylinder 7, which is wrapped with a layer of urethane rubber or the like for making the cutting easier and preventing the wear of cutting edge, with a predetermined timing of cuting and dieing.
  • the delivery conveyor (scrap conveyor) 10 is formed by a plurality of such carrier members as V-shaped belts or ropes having a circular section in an attempt to promote the dropping of chippings and cuttings from the product at the area where there is provided a specific means such as an air blower or a vibrator, and is constructed in a duplex structure for carrying the died board 11' in a sandwiched relationship over to a stacker-conveyor 12. There is provided a suction equipment in the stacker-conveyor 12.
  • the cardboard stopper 14 is designed shiftable back and forth by way of a hydraulic cylinder or the like in accordance with a given width of the died board 11' as schematically shown in FIGS. 1 and 2.
  • the cardboard box manufacturing machine is of the type that a sheet of cardboard 11 may be set either for one-piece cutting or for longitudinal double-piece cutting according to the size of a box to be died by using the die element 9 of the rotary die cutter 6.
  • FIG. 3(111) shows the case of the single-piece cutting process
  • FIG. 4(111) shows the longitudinal double-piece cutting
  • FIG. 4(IV) shows the four-piece cutting process (double-cuttings in the transversal and longitudinal ways making four pieces of boards), respectively.
  • the die element 9 is to be set in the circumferential surface of the die cut cylinder 8, with a single-piece or double-piece cutting knife element implanted in working position in accordance with the size of a product box to be manufactured, and with a spacing 16.
  • This spacing 16 is provided for the reduction of conveying speed in consideration of a too great shock to be given to the died cardboard 11' when hit against the cardboard stopper 14, which is taken in the following manner; when a series of died cardboards 11' after being died by the die cut cylinder 8 are stacked upon the lifter 17 by using the stacker-conveyor 12, as the carrying speed of the stacker-conveyor 12 will, when the single-piece cutting is conducted (FIG.
  • FIG. 6 Shown in FIG. 6 are an anvil cylinder 7, a die-cut cylinder 8, a die element 9, a sheet delivery conveyor (scrap conveyor) 10, a died sheet (through the double-piece cutting process) 11", a stacker-conveyor 12, a counter-stacker 13, a spacing 16, an photoelectric tube 32, and a sandwiching roll section 31, and shown in FIG. 8 are sandwich (rubber) roll elements 34, 34, a bearing 35, gears 36, and a DC (variable speed) motor 37.
  • FIG. 5 is a schematic diagram showing a series of died sheets 1 through 6 before delvered from the sandwich roll elements 34, 34, in which L depicts the circumferential length of the die-cut cylinder 8. Also in FIG.
  • FIG. 8 there is shown a timing chart showing the changes of rotating speed of the sandwich roll elements 34, 34.
  • the sandwich roll elements 34, 34 shown in FIG. 8 are fixed in operative position on a single roll shaft 33 disposed with a given gap, and are arranged opposedly to respectively form a pair of rolls in the sandwiching roll section 31.
  • Each of these sandwich roll elements 34 is formed with a layer of soft rubber sheet in its circumference so that it may not squeeze and crush the corrugated cardboard sheets while passing therethrough, and also may be worked with slitting.
  • the upper and lower roll shafts 33 are held rotatably by using the bearings 35 and operatively in such a manner that the cardboard sheet may be carried in a sandwiching manner by the engagement of the sandwich roll elements 34, 34, and on one sides of these roll shafts 33 there are fitted the gears 36 meshing with each other at the ratio of 1:1.
  • any change in the rotating speed of the sandwich roll elements 34, 34 may be accomplished by detecting the current edge position of a cardboard sheet to be fed at or near the central portion of the upper and lower sandwich roll elements 34, 34, and by feeding thus-obtained signal into the DC motor 37, and thus changing the rotating speed of the DC motor 37, accordingly.
  • the sheets 1, 2; 3, 4; 5, 6 depicts respectively the state of sheets fed from the blank cardboard supply station 1, or in other words the state that these sheets are disposed in a discrete relationship with each other.
  • the spaces between the sheets 2 and 3, and between @ and 6 represent a difference in the circumferential length of the die cut cylinder 8 and the overall extension of the died sheets 1 and 2.
  • ⁇ l represents a small gap produced between each of the adjacent died sheets.
  • the rotating speed (the circumferential speed of the roll surface) V 3 of the sandwich roll element 34 (or the rotating speed of the DC motor 37), which may be known by detecting the timing that the edge of the died cardboard 11' passes by using the photoelectric tube 32, is changed as shown in the timing chart of FIG. 7.
  • FIG. 7 shows the relationship between the timing of detecting the passage of the died cardboard 11' by the photoelectric tube 32 (that is, the case that the gap between the adjacent sheets is detected is defined to be the light receiving state, while the case that a sheet is detected being defined to be the light blocking state.) and the current rotating speed of the sandwich roll element 34.
  • the driving speed of the upper and lower sandwich roll elements 34, 34 is increased or reduced with the same speed rate in proportion to the rotating speed V 2 of the die cut cylinder 8.
  • FIG. 9 shows another embodiment of the invention wherein the rotating speed of the sandwich roll element 34 is changed by shifting a first electromagnetic clutch 40, etc. incorporated or installed otherwise in a motor 38 and a pulley and a second electromagnetic clutch 41, etc. incorporated or installed otherwise in a second motor 39 and a pulley, with which embodiment there is attainable an equivalent effect and function to that of the previous embodiment.
  • FIG. 10 shows a further embodiment of the invention, wherein the sandwich roll elements and the speed change device are replaced with a conveyor belt 44, a conveyor roll 45 and a motor 42, with which there is also attainable an equivalent effect and function to that of the embodiment described hereinbefore.
