Definitions

  • the present invention relates to a conveying and stacking apparatus for sheet bodies in which sheet bodies such as corrugated cardboard sheets or the like are conveyed and stacked on a stacking table in a laminated state.
  • GB-A-2 182 645 discloses an apparatus for forming separate batches of flat articles from a stream of such articles comprising conveying means for conveying said stream towards a movable stop, counting means for counting said articles as they approach said stop, and means responsive to said counting means for moving said stop to permit a batch having a given number of articles built up against said stop to be moved by said conveying means beyonds said stop.
  • the stop is movable both in generally vertical plane and in a generally horizontal plane along the direction of movement of the stream.
  • the responsive means causes said stop to rise and move towards said counting means in response to said counting having counted a given number of articles.
  • the conveying means can be driven at a first speed during formation of a batch and at a second higher speed during movement of said batch beyond said stop.
  • said stop is moved gradually away from said counting means under the combined action of said articles and said conveying means.
  • the stop is raised and moved back towards the counting means to permit delivery of said batch following which the stop is lowered again for the formation of the next batch.
  • FIG. 4(I) shows the entire construction of the same conveying and stacking system
  • Fig. 4(II) shows a portion A in Fig. 4(I) in enlarged scale.
  • reference numeral (1) designates a corrugated cardboard sheet
  • numeral (2) designates a stacking table
  • numeral (3) designates a feed roll
  • numeral (14) designates a press roll
  • numeral (15) designates a first conveyor
  • numeral (16) designates a second conveyor
  • numeral (12) designate a conveying surface of the respective conveyors (15) and (16)
  • numeral (17) designates a limit switch
  • numeral (18) designates an intermediate stopper disposed between the first conveyor (15) and the second conveyor (16).
  • the respective pieces are cut into a predetermined length in the widthwise direction by means of a cut-off and thus formed into corrugated cardboard sheets (1), and this corrugated cardboard sheet (1) is conveyed via an outlet side conveyor of the cut-off and enters the feed roll section (3), where it is pinched by the press roll (14) and forcibly ejected onto the first conveyor (15).
  • the first conveyor (15) is operated at a lower speed than the circumferential speed of the above-mentioned feed roll (3) and press roll (14), hence the corrugated cardboard sheets (1) ejected onto the first conveyor (15) are subjected to "shingling" (operation of stacking in a roof tile form), then they are ejected one by one onto the stacking table (2) via the second conveyor (16), and they are stacked on the stacking table (2) in a laminated state.
  • an upper surface level of the corrugated cardboard sheets (1) stacked in a laminated state on the stacking table (2) is detected by means of a photo-electric tube or the like, the detection signal obtained at that time is sent to an elevator driving device for the stacking table (2), so that the same elevator driving device would lower the stacking table (2) in accordance with the stacked amount, and thereby a level difference (5) between the ejecting end of the second conveyor (16) and the upper surface of the corrugated cardboard sheets (1) stacked in a laminated state on the stacking table (2) is maintained nearly constant.
  • the limit switch (17) operates, and thereby the stacking table (2) is lowered.
  • the second conveyor (16) stops, and the stacked corrugated cardboard sheets are delivered jointly with the stacking table (2) from the stacking position to the next step of the process. Also, at this moment, a conveying speed of the first conveyor (15) is switched to a low speed, a new stacking table (2) is brought to the above-mentioned stacking position and set there, and after an initial condition has been set, the second conveyor (16) is started and the corrugated cardboard sheets (1) held in a standby state would begin to be fed to the new stacking table (2).
  • the second conveyor (16) Upon this recommencement of feeding the second conveyor (16) is operated at a somewhat higher speed, so that the corrugated cardboard sheets (1) which are stagnating during the resetting of the stacking table (2) are quickly ejected onto the stacking table (2). Also, when these stagnating corrugated cardboard sheets (1) have been eliminated, the second conveyor (16) returns to a normal speed.
  • the new corrugated cardboard sheet (1a) in the foremost position may possibly mix in the old corrugated cardboard sheets (1b) in the rearmost portion as shown in Fig. 5(II), hence an assorting work for removing this mixed corrugated cardboard sheet in the next step is necessitated, and this lowered a working efficiency and became an obstacle in automation and energy saving of production.
  • ther is provided a novel conveying and stacking apparatus for sheet bodies having a conveying device for continuously conveying sheet bodies and a stacking table on which sheet bodies ejected from an end of the conveying device on the downstream side in the conveying direction are stacked, the sheet bodies being separated at every predetermined number of sheets and then conveyed and stacked, which apparatus includes at least one suction pad disposed at an inlet portion of the conveying device and adapted to selectively suck and stop the sheet body, and a plate disposed on the downstream side of the suction pad so as to be projected into and retracted from a conveying route of the sheet bodies.
  • the conveying and stacking apparatus since the conveying and stacking apparatus according to the present invention is constructed as described above, when the foremost one of the new sheet bodies has been fed as shingled on the rearmost one of the old sheet bodies, the suction pad or pads are actuated to suck the foremost one of the new sheet bodies, and thereby the foremost one of the new sheet bodies can be separated from the rearmost one of the old sheet bodies.
  • the plate disposed on the downstream side of the suction pad projects into the conveying route to stop the succeeding sheet bodies when the old sheet bodies have passed over the plate and thereby assures separation between the foremost one of the new sheet bodies and the rearmost one of the old sheet bodies.
  • reference numeral (1) designates corrugated cardboard sheets
  • numeral (1a) designates new corrugated cardboard sheets
  • numeral (1b) designates old cardboard sheets
  • numeral (2) designates a stacking table
  • numeral (3) designates a feed roll
  • numeral (4) designates a sucking device
  • numeral (5) designates a bracket for the same sucking device (4) and this bracket (5) is adapted to be raised and lowered in the direction of arrows in Fig. 2(I).
  • Reference numeral (6) designates suction pads in the same suction device (4), which are mounted to the bracket (5) in a vertically movable manner, and these suction pads (6) are provided in multiple as arrayed in the widthwise direction of the corrugated cardboard sheets (1), that is, in the direction perpendicular to the conveying direction of the corrugated cardboard sheets (1).
  • Reference numeral (19) designates spring for biasing the respective suction pads (6) upwards to hold them at a predetermined height, so that when the bracket (5) has been raised, the top surfaces of the respective suction pads (6) are raised up to a level slightly higher than a conveying surface (12) of the first conveyor (15).
  • reference numerals (7), (7′) and (7 ⁇ ) respectively designate connecting piped extending from the respective suction pads (6)
  • numerals (8), (8′) and (8 ⁇ ) respectively designate strainers provided in the connecting pipes (7), (7′) and (7 ⁇
  • numerals (9), (9′) and (9 ⁇ ) respectively designate electromagnetic valves provided in the connecting pipes (7), (7′) and (7 ⁇ ) respectively
  • numeral (10) designates a surge tank
  • numeral (11) designates a vacuum pump
  • numeral (9′′′) designates another electromagnetic valve provided in a connecting pipe that communicates the vacuum pump (11) with the above-mentioned surge tank (10), and provision is made such that a corrugated cardboard sheet (1) being conveyed towards the first conveyor (15) may be sucked by sucking the air within the respective suction pads (6) through the route of the connecting pipes (7), (7′) and (7 ⁇ ) ⁇ the strainers (8), (8′) and (8 ⁇ ) ⁇ the electromagnetic valves (9), (9′
  • a new corrugated cardboard web that is fed after the set valued at various portions have been changed, is transformed into new corrugated cardboard sheets (1a) via a cutting step similarly to the old corrugated cardboard web, then these corrugated cardboard sheets (1a) enter the feed roll (3) section through a conveyor on the outlet side of the cut-off, in this section they are forcibly ejected onto the first conveyor (15) as pinched by cooperation of the feed roll (3) and the press roll (14), and then they are subjected to shingling and placed on the old corrugated cardboard sheets (1b).
  • the old corrugated cardboard sheets (1b) are conveyed towards the stacking table (2) by the first and second conveyors (15) and (16) which are then driven at a high speed.
  • the respective suction pads (6) sucking the above-described new corrugated cardboard sheet (1a) releases the suction effect for the new corrugated cardboard sheet (1a), and thereby the new corrugated cardboard sheet (1a) is ejected onto the first conveyor (15).
  • the conveying and stacking apparatus for sheet bodies when the foremost one of new sheet bodies has been fed as shingled onto the rearmost one of old sheet bodies, the respective suction pads are operated to such the foremost one of the new sheet bodies, thereby the foremost one of the new sheet bodies is separated from the rearmost one of the old sheet bodies, and furthermore, the foremost portion of the new sheet bodies is stopped by the plate disposed on the downstream side of the suction pads, so that the new sheet bodies and the old sheet bodies can be surely separated from each other. Therefore, and advantage is obtained that an assorting work for mixed sheet bodies which was necessitated in the next step of the process in the prior art can be dispensed with.
