Definitions
- the present invention relates to an accumulating and delivering apparatus which stacks folded cardboard sheets being fed from a box making machine, collects them as an individual group of a predetermined number of the cardboard sheets, and delivers them therefrom.
- Japanese Patent Document 2000-127262(A1) discloses an accumulating and delivering apparatus which collects folded cardboard sheets being fed from a box making machine, stacks them up until a predetermined number is reached, and delivers them to.
- This accumulating and delivering apparatus includes an elevator for stacking sheets thereon which elevator is reciprocally moveable in the vertical direction between an upper transferring level at which an auxiliary ledge is disposed and a lower delivering level at which a delivering conveyer is disposed; a ledge which is reciprocally moveable in the vertical direction between an upper waiting level at which it does not receive the sheets being fed and a lower transferring level at which auxiliary ledge is disposed, and which ledge protrudes in the direction upstream of the sheet feeding direction in order to obstruct the sheet vertical path area; and an auxiliary ledge for obstructing the sheet vertical path area by protruding it in the direction lateral to the sheet feeding direction during a period of time from when the elevator starts moving downwardly from its upper transferring level to when the
- the cardboard sheets being fed are stacked on the elevator at the upper transferring level. Thereafter, when the stacked sheets reaches a predetermined number, the elevator is moved downwardly to the lower delivering level in order to deliver the group of sheets stacked on the elevator using a delivering conveyer, while the ledge is moved downwardly with the cardboard sheets being fed stacked thereon by using the ledge protruded in a direction upstream of the sheet feeding direction. Then, when the ledge has been moved downwardly to the lower transferring level, the group of sheets stacked on the ledge is transferred onto the auxiliary ledge and the ledge is moved to the upper waiting level. Next, when the elevator has been moved to the upper transferring level at which the auxiliary ledge is disposed, the group of sheets stacked on the auxiliary ledge is transferred onto the elevator.
- One object of the present invention is to provide an apparatus for accumulating and delivering groups of sheets which can be reduced in cost and improved in reliability thereof due to a simplified construction of the apparatus and facilitated control of the movement of the ledge.
- Another object of the present invention is to provide an apparatus for accumulating and delivering groups of sheets which can effectively prevent the spring-back of the group of sheets stacked on the stacking base even when the sheets are supported on the ledge.

- the sheets being fed are stacked one by one on the stacking base in its stacking position, forming a group of the sheets including a predetermined number of the sheets, and when the first sheet in the next group of the sheets is being fed based on the information of the number of the sheets stacked on the stacking base, the ledge positioned between the sheet feeding level and the stacking position level is protruded from its waiting position to its sheet receiving position located in a direction downstream of the sheet feeding direction while the stacking base is vertically moved from its stacking position to its delivering position, whereby it becomes possible to stack the sheets on the ledge until the stacking base returns back again to its stacking position without any risk of errors in receiving the first sheet being made.
- the group of the sheets stacked on the ledge can be transferred onto the stacking base by retracting the ledge from its sheet receiving position to its waiting position.
- Transferring the group of the sheets from the stacking base to the ledge is accomplished just by protruding the ledge from its waiting position to its sheet receiving position in a direction downstream of the sheet feeding direction, while transferring the group of the sheets from the ledge to the stacking base is accomplished just by retracting the ledge from its sheet receiving position to its waiting position in a direction upstream of the sheet feeding direction, whereby the movement control of the ledge and construction of the apparatus can be simplified, and thus the cost there is reduced and reliability is improved.

Abstract
Description
- The present invention relates to an accumulating and delivering apparatus which stacks folded cardboard sheets being fed from a box making machine, collects them as an individual group of a predetermined number of the cardboard sheets, and delivers them therefrom.
- Japanese Patent Document 2000-127262(A1), for example, conventionally, discloses an accumulating and delivering apparatus which collects folded cardboard sheets being fed from a box making machine, stacks them up until a predetermined number is reached, and delivers them to. This accumulating and delivering apparatus includes an elevator for stacking sheets thereon which elevator is reciprocally moveable in the vertical direction between an upper transferring level at which an auxiliary ledge is disposed and a lower delivering level at which a delivering conveyer is disposed; a ledge which is reciprocally moveable in the vertical direction between an upper waiting level at which it does not receive the sheets being fed and a lower transferring level at which auxiliary ledge is disposed, and which ledge protrudes in the direction upstream of the sheet feeding direction in order to obstruct the sheet vertical path area; and an auxiliary ledge for obstructing the sheet vertical path area by protruding it in the direction lateral to the sheet feeding direction during a period of time from when the elevator starts moving downwardly from its upper transferring level to when the ledge reaches the lower transferring level.
- In accordance with this construction, the cardboard sheets being fed are stacked on the elevator at the upper transferring level. Thereafter, when the stacked sheets reaches a predetermined number, the elevator is moved downwardly to the lower delivering level in order to deliver the group of sheets stacked on the elevator using a delivering conveyer, while the ledge is moved downwardly with the cardboard sheets being fed stacked thereon by using the ledge protruded in a direction upstream of the sheet feeding direction. Then, when the ledge has been moved downwardly to the lower transferring level, the group of sheets stacked on the ledge is transferred onto the auxiliary ledge and the ledge is moved to the upper waiting level. Next, when the elevator has been moved to the upper transferring level at which the auxiliary ledge is disposed, the group of sheets stacked on the auxiliary ledge is transferred onto the elevator.
- By repeating these cycles, it is possible to collect the folded cardboard sheets being continuously fed from a box making machine, stack them up until a predetermined number is reached, and deliver them therefrom as an individual group of the sheets.
- However, these accumulating and delivering apparatus have several technical disadvantages as follows:
- Firstly, it is difficult to control the movement of the ledge. More particularly, when the ledge is in the upper waiting level, the ledge is maintained in a position protruding toward the upstream of the sheet feeding direction, and at the moment when a predetermined number of sheets is stacked on the elevator, during the time the next sheet is passing through the sheet vertical path area, the next sheet is received on the upper surface of the ledge by moving it downwardly by a desired distance. Thus, during the time period from when the last sheet in the predetermined number has been passed below the ledge to when the next sheet passes through the sheet vertical path area and drops on the upper surface of the group of the sheets located in the delivering position, it is necessary for the ledge to pass this sheet and receive this sheet on its upper surface, which makes it difficult to control the ledge with respect to the vertical movement of the sheet.
- Secondly, the construction of the accumulating and delivering apparatus in relation to the ledge is complicated, thereby the cost is increased and the reliability of the accumulating and delivering apparatus is decreased. More particularly, since the group of the sheets is delivered to the delivering conveyer in the lower delivering level, the next group of sheets being stacked on the ledge must be kept there during the period of time from when the group of sheets has been delivered by the delivering conveyer to when the elevator is moved to the upper transferring level. Furthermore, the ledge must be moved to the upper waiting level in order to receive the next group of sheets. Therefore, it is necessary to provide an auxiliary conveyer in order to hold the group of the sheets during the time the group of the sheets is being transferred from the ledge onto the elevator.
- Thirdly, the spring-back of the sheet stacked as a group of the sheets cannot be effectively prevented. More particularly, a blower is disposed above the elevator, and the air blown from this blower is directed through the sheet vertical path area onto the upper surface of the elevator, and thus the spring-back of the group of the sheets stacked on the upper surface of the elevator can be prevented. However, when the ledge is being protruded, since the ledge blocks the air from the blower, it is difficult to prevent the spring-back of the group of the sheets located below the ledge.

- One object of the present invention is to provide an apparatus for accumulating and delivering groups of sheets which can be reduced in cost and improved in reliability thereof due to a simplified construction of the apparatus and facilitated control of the movement of the ledge.
- Another object of the present invention is to provide an apparatus for accumulating and delivering groups of sheets which can effectively prevent the spring-back of the group of sheets stacked on the stacking base even when the sheets are supported on the ledge.
- According to one aspect of the present invention, there is provided an accumulating and delivering apparatus for a group of sheets being fed one by one comprising a stacking base for stacking said sheets on its stacking surface, a stacking base driving means for moving said stacking base in a vertical direction between a stacking position for stacking said sheets on said stacking base as a group and a delivering position for delivering said group of said sheets, a ledge for supporting said sheets being fed from below when said stacking base is moved out from its stacking position, and a ledge controlling means for controlling the movement of said ledge, wherein: said ledge is a single ledge positioned at a desired level located between a level corresponding to said stacking position and a sheet feeding level; further comprising a ledge reciprocating driving means for moving said single ledge reciprocally in the sheet feeding direction between a sheet receiving position for receiving said sheets to be stacked on said stacking base above said stacking position and a waiting position which is located upstream in the sheet feeding direction from said sheet supporting position; and said ledge controlling means controlling said ledge reciprocating driving means so as to start moving said single ledge from said waiting position to said sheet receiving position, based on the information of the number of said sheets stacked on said stacking base.
- In accordance with the above mentioned construction, the sheets being fed are stacked one by one on the stacking base in its stacking position, forming a group of the sheets including a predetermined number of the sheets, and when the first sheet in the next group of the sheets is being fed based on the information of the number of the sheets stacked on the stacking base, the ledge positioned between the sheet feeding level and the stacking position level is protruded from its waiting position to its sheet receiving position located in a direction downstream of the sheet feeding direction while the stacking base is vertically moved from its stacking position to its delivering position, whereby it becomes possible to stack the sheets on the ledge until the stacking base returns back again to its stacking position without any risk of errors in receiving the first sheet being made. When the stacking base returns back again to its stacking position, the group of the sheets stacked on the ledge can be transferred onto the stacking base by retracting the ledge from its sheet receiving position to its waiting position.
- Transferring the group of the sheets from the stacking base to the ledge is accomplished just by protruding the ledge from its waiting position to its sheet receiving position in a direction downstream of the sheet feeding direction, while transferring the group of the sheets from the ledge to the stacking base is accomplished just by retracting the ledge from its sheet receiving position to its waiting position in a direction upstream of the sheet feeding direction, whereby the movement control of the ledge and construction of the apparatus can be simplified, and thus the cost there is reduced and reliability is improved.
- In one embodiment of the present invention, said ledge has a press lever on the lower surface thereof for pressing said sheets stacked on said stacking surface.
- In another embodiment of the present invention, said ledge has a groove on the lower surface thereof for containing said press lever therein; said press lever being attached on said lower surface of said ledge to be pivotable between an accommodated position in which said press lever is contained in said groove and a pressing position.

- As can be seen in Figure 1,
reference numeral 1 indicates a machine frame, whichmachine frame 1 includes a pair ofinlet rollers cardboard sheets 6 being fed one by one between theinlet rollers feeding conveyer 8 is disposed at a downstream side of theinlet rollers feeding roller 10 is disposed at the front end of thefeeding conveyer 8. A guidingplate 12 is disposed in a direction of feeding of thecardboard sheets 6 from thefeeding conveyer 8 andfeeding roller 10 in such a manner that the front end of thecardboard sheet 6 comes into contact with the guidingplate 12. - The guiding
plate 12 is mounted on asliding plate 14 moveably supported along a rail 16 which is mounted on themachine frame 1. The rail 16 is mounted to be parallel to thecardboard sheet 6 which is to be stacked on either one ofstacking bases sliding plate 14 can be moved along the rail 16 by rotating a threaded shaft 17b which is driven by a motor 17a mounted on themachine frame 1. - An
air blower 18 is mounted at the top of themachine frame 1, and the air blown therefrom is directed toward thecardboard sheet 6 being fed by thefeeding conveyer 8 and thefeeding roller 10. An aligningplate 20 is disposed adjacent to the front end of thefeeding conveyer 8 opposite to the guidingplate 12 in such a manner that thecardboard sheet 6 fed by thefeeding conveyer 8 will drop in between the guidingplate 12 and thealigning plate 20. A ledge 22 is disposed below thefeeding conveyer 8, which ledge 22 can be projected toward the guidingplate 12 through a window formed on the aligningplate 20. When the ledge 22 is projected, thecardboard sheets 6 can be stacked thereon.
In this embodiment, four sets ofstacking bases stacking bases cardboard sheet 6. As shown in Fig.9, two sets ofstacking bases stacking bases stacking bases corresponding driving mechanisms 28, respectively, while the two sets ofstacking bases corresponding driving mechanisms 30, respectively.
The height of each of thestacking bases cardboard sheets 6 will not be dislocated or damaged when thecardboard sheets 6 supported on theledge 90 are dropped and/or transferred onto the upper surface of each of thestacking bases - In this embodiment, the four sets of
stacking bases plate 12 and thealigning plate 20, and support thecardboard sheets 6 from below in order to stack a predetermined number of them, whereby a group of sheet is collected.
Since four sets ofstacking bases driving mechanisms - As can be seen in Figures 5 and 7, the
stacking bases 24 in thestacking bases stage 36 via a pair ofrails stage 36 is moveably supported on arail 38 disposed in a frontward/rearward direction of themachine frame 1. As can be seen in Figure 8, thestacking bases 26 are mounted on a moving stage 46 via a pair of rails 42 (only one is shown) which are disposed in an upward/downward moving direction. The moving stage 46 is moveably supported on a rail 48 disposed in a frontward/rearward direction of themachine frame 1. - A
spline shaft 50 is rotationally mounted on themachine frame 1 to be a parallel to therails 38 and 48, as shown in Figure 5, and a pair ofpulleys spline shaft 50 in such a manner that they can be slidably moveable along thespline shaft 50, whereas they are fixed as to the rotational movement of thespline shaft 50, as shown in Figures 7 and 8. One of thepulleys 52 is rotationally mounted on the movingstage 36, while the other one of thepulleys 54 is rotationally mounted on the moving stage 46. - Pulleys 56 and 58 are rotationally mounted below a pair of moving
stages 36 and 46, respectively. As can be seen in Figure 7, atiming belt 60 is wound around the pulley 56 and thepulley 52, both of which are mounted on the movingstage 36. A portion of thetiming belt 60 is affixed on the stackingbase 24 via a mounting member 61. As can be seen in Figure 8, a timing belt 64 is wound around the pulley 58 and thepulley 54, both of which are mounted on the moving stage 46. A portion of the timing belt 64 is affixed on the stackingbase 26 via a mounting member 63. - As can be seen in Figure 5, the
spline shaft 50 is rotationally driven via a belt transmission device 66 and a servo motor 64 mounted on themachine frame 1. When thespline shaft 50 is rotated in one direction, the stackingbase 24 is moved upwardly while the stackingbase 26 is moved downwardly. On the contrary, when thespline shaft 50 is rotated in the direction opposite to said one direction, the stackingbase 24 is moved downwardly while the stackingbase 26 is moved upwardly. In this way, each of the stackingbases bases bases spline shaft 50. - As can be seen in Figures 5 and 6, pairs of
pulleys 68 and 70 are mounted on themachine frame 1 in a spaced apart relationship along the longitudinal direction thereof, andtiming belts 72 are wound around each pair of thepulleys 68 and 70, respectively. A pair of the movingstages 36 and 46 are affixed on each one of thetiming belts 72 by mounting members 73a and 73b. - A
large pulley 74 is fixedly attached on each of the pulleys 68, and atiming belt 80 is wound around each of thelarge pulleys 74 and each drivingpulley 78 mounted on a servo motor 76 which is mounted on themachine frame 1. When thetiming belt 80 is rotationally driven in one direction, the movingstage 36 is moved frontward while the moving stage 46 is moved rearward. On the contrary, when thetiming belt 80 is rotationally driven in the direction opposite to said one direction, the movingstage 36 is moved rearwards while the moving stage 46 is moved frontward. In this way, the movingstages 36 and 46 are moved by the rotation of thetiming belt 80 in frontward or in rearward directions along the feeding direction of thecardboard sheets 6, as shown in Figure 6, between their first position in the feeding direction and their second position in the feeding direction located to the rearward of the first position with respect to the feeding direction of thecardboard sheets 6. - In this embodiment, two of the driving
mechanisms 28 are driven by the commonly used servo motors 64 and 76 in such a manner that two of thespline shafts 50 are driven by only one servo motor 64, while twotiming belts 72 are driven by only one servo motor 76. The servo motors 64 and 76 are connected to a controlling device 81, as shown in Figure 5, and the servo motors 64 and 76 are driven while their rotating speed is being controlled in accordance with the signal supplied from the controlling device 81. - The
driving mechanism 28 enables each of the stackingbases base 24 is moved frontward toward its first position in the feeding direction as well as upwardly toward its first upper level, it moves toward the stacking position for stacking thecardboard sheets 6 thereon, as shown in Figure 1. When the stackingbase 24 is moved downwardly from this stacking position to its second lower level, it moves toward the delivering position, as shown in Figure 2, and when the stackingbase 24 is moved rearward from the delivering position to its second position in the feeding direction, it moves toward the resting position, as shown in Figure 3. Furthermore, when the stackingbase 24 is moved upwardly from the resting position to its first upper level, it moves toward the ejecting position, as shown in Figure 4, and when the stackingbase 24 is moved frontward from the ejecting position to its first position in the feeding direction, again it moves toward the stacking position, as shown in Figure 1. In this way, the stackingbase 24 can be moved along a rectangular-shaped loop which connects the stacking position, the delivering position, the resting position and ejecting position, the stackingbase 24 being indexed at each of these positions. The stackingbase 26 is moved in the same manner, but the movement thereof is 180 degrees different from that of the stackingbase 24. In this way, the pair of stackingbases bases bases bases bases bases cardboard sheets 6 in order to obtain stable stacking of thecardboard sheets 6, and the number of the stacking bases may be increased as well. - As can be seen in Figures 7 and 8,
roller conveyers 82 are disposed along both sides of thedriving mechanism 28 in such a manner that the top surface of theroller conveyers 82 is positioned above the top surface of the stackingbases conveyer 84 and a transport conveyer 86 are disposed along with theroller conveyers 82. Apress conveyer 88 is disposed above the ejectingconveyer 84, which pressconveyer 88 is adjustable as regards its distance from the ejectingconveyer 84. - As can be seen in Figure 1, a
ledge 90 is disposed below the feedingconveyer 8, whichledge 90 is reciprocally moveable along the feeding direction of thecardboard sheets 6 via aledge driving mechanism 92, as shown in Figure 10. More particularly, theledge 90 is reciprocally moveable along the feeding direction of the cardboard sheets between its sheet receiving position in which the ledge protrudes through a window 20a formed in the aligningplate 20 toward the guiding plate 12 (see Figure 10) and its waiting position located in a direction downstream of the sheet feeding direction (see Figure 1). The ledge has an upper surface which is large enough to receive and stack thereon the cardboard sheets being fed when it is in its sheet receiving position, and the ledge may be divided, for example, into four parts across the width direction of the cardboard sheet to form a fork-like shape. - The
ledge 90 has apress lever 98 on the lower surface thereof for pressing the cardboard sheets stacked on the stacking surface. As can be seen in Figure 11, thepress lever 98 is formed in a L-shaped manner, and one end of thepress lever 98 is connected to the rod of acylinder 102 while the other end thereof includes aflat spring 104 which presses the upper surface of a group of sheets being stacked. Thecylinder 102 is, for example, a trunion cylinder which is supported integrally together with theledge 90. As can be seen in Figure 11, theledge 90 has a longitudinal groove 96 the opening of which faces in a downward direction, and the length of the groove 96 is adapted to contain thepress lever 98 therein. Thus, thepress lever 98 is pivotable between an accommodated position in which the press lever is contained in the groove 96 and a pressing position for pressing the upper surface of the group of sheets being stacked in the delivering position (see Figure 2). - As can be seen in Figure 10, the
ledge driving mechanism 92 includes astraight rail 94 mounted on themachine frame 1, and therail 94 is mounted along the feeding direction of thecardboard sheets 6 by the feedingconveyer 8 in such a manner that it is slightly angled upwardly toward a direction downstream of the feeding, and theledge 90 is supported moveably along therail 94. This angle can be selected to facilitate the receiving of thecardboard sheets 6 when theledge 90 is protruded. Theledge driving mechanism 92 has a driving source (not shown) which moves theledge 90 reciprocally along therail 94 between its sheet receiving position and its waiting position. - The number of the cardboard sheets stacked on the stacking
bases - The operation of the accumulating and delivering apparatus of the embodiment described above will now be explained below.
- When a folded
cardboard sheet 6 is fed from a box making machine (not shown) to this apparatus, thecardboard sheet 6 is received by theinlet rollers cardboard sheet 6 is then carried by the feedingconveyer 8 and the feedingroller 10, to be transferred toward the guidingplate 12. When the front end of thecardboard sheet 6 comes into contact with the guidingplate 12, thecardboard sheet 6 will drop in between the guidingplate 12 and the aligningplate 20 along inner faces of the guidingplate 12 and the aligningplate 20. - At this time, an air flow supplied by the
air blower 18 prevents the foldedcardboard sheet 6 from being unfolded and pushes thecardboard sheet 6 against the top surface of the stackingbase 24. Air outlets of theblower 18, as shown in Figure 9, extend across the width of thecardboard sheets 6, although the location and/or number of the air outlets of theblower 18 may vary depending on the width of thecardboard sheets 6. The position of the guidingplate 12 is adjusted by moving the slidingplate 14 which is driven by the motor 17a in such a manner that the distance between the guidingplate 12 and the aligningplate 20 is generally made to correspond to the length of thecardboard sheet 6. - In this way, the
cardboard sheet 6 is stacked on the stacking bases 24. As can be seen in Figure 1, thecardboard sheets 6 being successively fed are stacked on the stackingbases 24 one by one, and the number of thecardboard sheets 6 is detected by a sensor (not shown). When the number of thecardboard sheets 6 reaches a predetermined number, thecardboard sheets 6 form a group stacked on the stackingbases 24, and the ledge 22 is projected through the aligningplate 20, whereby thecardboard sheets 6 are temporarily supported on the ledge 22. - More particularly, when the sensor detects a predetermined number of
cardboard sheets 6 has been stacked on the stackingbase 24, the detection signal is then transmitted to theledge driving mechanism 92, whereby theledge 90 starts protruding from its waiting position to its sheet receiving position. As long as the protruding speed of theledge 90 is selected properly, there is no risk of making an error in receiving thenext cardboard sheet 6 on the upper surface of theledge 90, because theledge 90 is protruded in a direction downstream of the sheet feeding direction. - Thereafter, the stacking
bases corresponding driving mechanisms bases 24 with the cardboard sheets stacked thereon (Figures 6 and 9 show a group of the sheets stacked on the stacking bases 24) are moved from its stacking position to its delivering position. The stackingbases 26 are moved upwardly from its resting position to its ejecting position. When the stackingbases 24 are moved downwardly toward its delivering position, thestacked sheets 6 are supported on theroller conveyer 82. - Next, as can be seen in Figure 2, the
cardboard sheets 6 stacked on theledge 6 are prevented from causing spring-back by theblower 18, while the air from theblower 18 is interrupted by theledge 6 because theledge 6 is in its protruded position, as to the group of the sheets located below theledge 6, since thepress lever 98 is pivoted from its waiting position to its pressing position and the pressing force of theflat spring 104 keeps pressing down the upper surface of the group of the sheets on the stackingbases 24, the foldedcardboard sheets 6 are prevented to cause spring-back or to be dislocated. - Thereafter, as can be seen in Figure 3, the stacking
bases 24 are moved back from its delivering position to its resting position located in a direction opposite to the sheet feeding direction by driving thedriving mechanism 28. At the same time, the stackingbases 26 are moved forwardly from its ejecting position to its stacking position located in a direction forward of the sheet feeding direction. At this time, thesheets 6 on theroller conveyer 82 are pushed out in a direction upstream of the sheet feeding direction by the front end of the stackingbases 26, whereby thesheets 6 are transferred onto the ejectingconveyer 84. Thestacked sheets 6 on the ejectingconveyer 84 are held with apress conveyer 88, transferred onto the transport conveyer 86, and then delivered from the transport conveyer 86. - Next, after the stacking
bases 26 are moved to its stacking position, the ledge 22 is retracted from its sheet receiving position to its waiting position in a direction upstream of the sheet feeding direction, whereby the group of sheets on the ledge 22 is dropped to be transferred on the upper surface of the stackingbase 26 in its stacking position. At this time, the height of the stacking base may be adjusted to prevent an adverse effect on the group of the sheets upon their being drop. Next, thecardboard sheets 6 continuously fed are stacked on the stackingbases 26, and when a predetermined number of sheets has been stacked thereon, the ledge 22 is again, protruded from its waiting position to its sheet receiving position in a direction downstream of the sheet feeding direction, whereby thesheets 6 are stacked on the ledge 22. Although in this embodiment the ledge 22 starts retracting after the stackingbases 26 are moved to its stacking position, retracting of the ledge 22 may be started while the stackingbases 26 are still moving toward its stacking position. - Thereafter, as can be seen in Figure 4, the stacking
bases 26 are moved from its stacking position to its delivering position, whereby thecardboard sheets 6 stacked thereon are supported on theroller conveyer 82. At the same time, the stackingbases 24 are moved upwardly from its resting position to its ejecting position. Next, the stackingbases 26 are moved back to its resting position, while the stackingbases 24 are moved frontward from its ejecting position to its stacking position, whereby thecardboard sheets 6 supported on theroller conveyer 82 are pushed out by the front ends of the stackingbases 24, and transferred onto the ejectingconveyer 84. By repeating these operations, thecardboard sheets 6 being continuously fed can be delivered out from this apparatus in the form of separated units each consisting of a predetermined number of thecardboard sheets 6. - Although this invention has been disclosed with respect to a specific embodiment which is an example thereof, those skilled in the art will be able to realize the invention in different embodiments without departing from the spirit and scope of the invention.
