残存している。Generally, in an integrated production line for plate-shaped sheets, such as corrugated sheets, the long corrugated pole sheets produced are separated and cut into plate-shaped sheets of a predetermined size using a slitter and rotary cutter near the final process, and then slotted. Others are transported to the next process where they undergo leasing (horizontal purchase line) processing. In this case, the corrugated cardboard sheets cut to a fixed size are carried on a belt conveyor and transported, and are sequentially dropped onto a transport conveyor, generally consisting of a roller conveyor, to be delivered as a predetermined number of stacked sheets. However, when the sheets are dropped and released, their posture may be disturbed due to the influence of air resistance, so it is actually difficult to stack the sheets in an orderly manner. For example, as shown in FIG.
When stacking is performed by dropping onto the transport conveyor 14 located diagonally below the tip of the roller member 1 of the transport conveyor 14, even if the position of the receiver is adjusted by the stopper 16 that slides back and forth, the roller member 1 of the transport conveyor 14
Since there is a considerable drop between the sheet 8 and the open end of the belt conveyor 12, the sheet 10 is affected by the air resistance mentioned above, and the posture of the sheet t1 in the lower layer is disturbed. This means that they cannot be layered in an orderly manner. (In the case of Figure 1,
Of course, the roller member 18 stops rotating when the sheet 10 is dropped and discharged.) Furthermore, as a transport conveyor, a structure shown in FIGS. 2 and 3 has been separately proposed. This is constructed by disposing one elongated crosspiece member 20 between each of the roller members 18 disposed in large numbers on the conveyor 14, and allowing these crosspiece members 20 to be raised and lowered by an appropriate lifting mechanism. As shown in FIG. 3, when the crosspiece member 20 is raised to the level /, it is located above the upper surface level 12 of the roller member 18,
When it is lowered to level j1, it is located below the upper surface level 12. When receiving falling sheets 10, the slatted frame member 20 is raised to level It, and when stacking of sheets 10 is completed, the bar member 20 is lowered to level 13, and the sheet stack is assembled. is carried out laterally by the rotation of the roller member 18. This is different from the transport conveyor shown in FIG. 1, since the roller member 18 can be kept rotating at all times, there is no need for complicated starting and stopping operations of the roller member 18, but the cross member 20 and the belt conveyor Since there is still a considerable drop between the seat 10 and the open end of the seat 12, there remains a concern that the posture of the seat 10 may be disturbed due to air resistance.

た。Therefore, the shadow due to air resistance during the falling release of C) 10′
In order to solve this problem, a conveyor having the structure shown in FIGS. 4 and 5 was separately proposed. This is the conveyor 14
A frame-shaped crosspiece frame member 2 is placed between each rotating roller member 18 of
2 are arranged correspondingly to each other, and the crosspiece frame members 22 are connected to appropriate elevating members 24 as shown in the figure, so that the crosspiece frame member 22 on the stone side close to the open end of the belt conveyor 12 is tilted. It is constructed so that it can be raised and lowered. In this conveyor 14, when the sheet 10 is supplied by falling, the frame member 22
Since the sheet is tilted upward and approaches the open end of the belt conveyor 12, there is almost no head difference, and therefore sheets can be piled up in an orderly manner without being affected by air resistance. . However, in this conveyor 14, the following inconvenience occurs when the stacking of the sheets 10 is finished in an orderly manner and the frame member 22 is tilted and lowered. That is, sheet 1
0 generally refers to a number of rows 22 that are pivotally supported on the side surface of the crosspiece frame member 22.
As shown in FIG. However, since the frame member 22 is tilted about the axis 28, the entire bottom surface of the sheet stack is simultaneously transferred to the upper surface of the roller member 18. Instead of coming into contact with the roller member IB, it comes into contact with the roller member IB from the bottom side of the sheet 10 that is held by the stopper 16. At this time, since the row 2 member 18 is constantly rotating, torsional stress is applied to the bottom edge of the stacked sheets 10, which may cause the posture of the assembled stack to collapse or the stack to be stacked against the direction of transport by the roller member 18. It has been pointed out that the entire body is biased, which has an adverse effect on smooth processing in the next process.

を目的とする。In view of the various drawbacks inherent in the prior art conveyor for conveying plate-like sheets, the present invention has been proposed to eliminate disturbances in the posture of sheets when they are dropped and discharged, and to stack the sheets in an orderly manner. It is an object of the present invention to provide a transport conveyor configured such that the entire bottom surface contacts a rotating roller member at the same time so that a stack of sheets is not biased in the transport direction.

。In order to achieve this object, in the present invention, a large number of roller members are rotatably arranged at predetermined intervals, and crosspiece members are alternately arranged adjacent to the roller members, and the crosspiece members are arranged to rotate around the rollers. In a conveyor configured to move horizontally upward and downward from the upper surface level of a member as a reference level, 1. An auxiliary crosspiece member is disposed adjacent to the crosspiece member so as to be tiltable up and down, and the tilting lowering speed of the auxiliary crosspiece member is set higher than the horizontal descending speed of the crosspiece member. The crosspiece member is tilted upward and downward from the upper surface level of the crosspiece member as a reference. Also, each auxiliary crosspiece member is configured to be rotatably pivoted to each crosspiece member at one end thereof. is suitable.

効果が得られる。Historically, a combination of a link mechanism connected to the crosspiece and the auxiliary crosspiece, and a fluid pressure cylinder connected to this link mechanism was used as a driving means for horizontally raising and lowering the crosspiece and tilting and raising and lowering the auxiliary crosspiece. It is recommended that you do so. In addition, instead of this driving means, bell cranks are connected to the crosspiece member and the auxiliary crosspiece member respectively, so that the descending speed of the fluid pressure cylinder connected to the auxiliary crosspiece member is higher than the descending speed of the fluid pressure cylinder connected to the crosspiece member. Even if the setting is made, the same effect can be obtained.

た周速で回転する送出しロー２を示す。Further, in the present invention, an auxiliary bar member 60 is disposed adjacent to the bar member 32 so as to be tiltable and vertically movable. This auxiliary beam member 60
is composed of a plate-shaped piece having substantially the same standard as the crosspiece member 32 and shorter than this, and is pivoted at one end via a shaft pin 62 on the side of each crosspiece member 32, as shown in FIG. It is pivoted freely. Further, the bell crank 38 has an arm on the side that is pivoted to the connecting rod 44 (this will be referred to as a "drive arm" and will be designated by reference numeral 64) and an arm on the opposite side as shown in the figure. The first arm 66 is bifurcated into a first arm 66 and a second arm 68.
As described above, the supporting tongue piece 34 of the crosspiece member 32 is attached to the shaft pin 40.
At the same time, the tip of the second arm 68 and the other end of the auxiliary beam member 60 are connected via a support rod 70. In this embodiment, the upper end of the support rod 70 is connected to the auxiliary beam member 6.
The lower end of the support rod 68 is jointly connected to the lower end edge of the second arm 68 by, for example, a ball joint, and the lower end of the support rod is inserted into a long hole 72 formed at the tip of the second arm 68 and is in a loose state. In this case, the first
Angles α and β formed by arm 66 and second arm 68, respectively
is set in advance so that α>β and the relationship between the length a of the first arm and the length b of the second arm is a (b) as shown in FIG. With this configuration, the vertical movement speed of the tip of the first arm 66 and the tip of the second arm 68 of the bell crank 38 is such that the tip of the second arm 68 is always greater than the tip of the first arm 66. As a result, the tilting downward speed of the auxiliary crosspiece member 60 is set to be greater than the horizontal downward speed of the crosspiece member 32, as will be described later. Reference numeral 16 indicates a stopper, which is used to stop the plate-like sheet lO falling onto the conveyor 14.
The belt conveyor 12 can be adjusted forward and backward along the roller member 18 according to the length of the belt conveyor 12.
A delivery row 2 is shown spaced apart from the tip of the belt conveyor and rotating at a circumferential speed synchronized with the belt conveyor.

In use, this conveyor 14 is arranged obliquely below the open end of the belt conveyor 12 so that the open end of the auxiliary crosspiece member 60 is directed toward the belt conveyor 12 as shown in FIGS. As shown in FIG. 7, the auxiliary beam member 60 is tilted and raised to wait for the plate-like sheet 10 to be dropped and supplied. That is, by energizing the double-acting pneumatic cylinder 52 to retract the piston rod 56 into the cylinder tube and actuating the linkage comprised of the bell crank 36, 38 and the connecting rod 44, as previously described. The crosspiece member 32 rises horizontally above the upper surface level of the roller member 18, and the crosspiece member 32 is raised horizontally above the level of the upper surface of the roller member 18, and the crosspiece member 32 is raised horizontally to the roller member 18 in a slatted edge shape.
Make it more prominent. At this time, the second arm 68 of the bell crank 38 has a greater upward movement distance than the first arm 66, so the auxiliary crosspiece member 60 tilts upward as well as the upper surface level of the crosspiece member 32, as shown in FIG. It rises and comes into close proximity to the belt conveyor 12 (and in the illustrated embodiment, the delivery rollers 74).

である。In this state, the corrugated cardboard sheets 10 supported in a shimbling manner on the belt conveyor 12 are conveyed one after another, and are dropped and discharged onto the conveyor 14 in a slightly oblique position via the delivery rollers 74. At this time, since the auxiliary crosspiece member 60 is protruding and waiting in an inclined state above the crosspiece member 32 of the conveyor 14, the fallen corrugated cardboard sheet 10 is not affected by the air resistance due to the drop at all, and the auxiliary crosspiece member 60 is in a standby position above the crosspiece member 32 of the conveyor 14. They land on the member 60 and are sequentially and orderly stacked. When a predetermined number of corrugated sheets 10 have been stacked, a signal is sent to a switching pulp (not shown) of the pneumatic cylinder 52 to reverse bias the pneumatic cylinder 52. This causes the piston rod 56 to extend from the cylinder tube, and as a result of reversely operating the link mechanism, the horizontal lowering of the bar member 32 and the tilting lowering of the auxiliary bar member 60 are simultaneously started. At this time, as mentioned earlier, the angle α formed by the first arm 66 with respect to the drive arm 64 of the bell crank
is also larger than the angle β formed by the second arm 68, and
Since the length a of the arm 66 is set smaller than the length b of the 27th arm 68, the tilting downward speed and distance of the auxiliary crosspiece member 60 are greater than the horizontal downward speed and distance of the crosspiece member 32. Therefore, the auxiliary crosspiece member 60 on which the corrugated cardboard sheets 10 are stacked is quickly tilted down relative to the crosspiece member 32. Therefore, the stack of corrugated cardboard sheets 10 is smoothly transferred from the auxiliary crosspiece member 60 to the crosspiece member 32, and since the crosspiece member 32 continues to descend horizontally during this time, the crosspiece member 32 is finally transferred. The upper surface level becomes lower than the upper surface level of the roller member 18, and the sheet stack maintains a horizontal state and is further transferred onto the roller member 18. Since the bottom surface of the roller member 10 lands uniformly on the entire top surface of the roller member 10, the bottom surface of the roller member 10 is twisted and deviates in its posture with respect to the sending direction, as in the conventional conveyor shown in FIGS. 4 and 5. Things completely disappear. In addition,
Since the roller member 18 is constantly rotating, the sheet stack is conveyed in a direction perpendicular to the direction of conveyance by the belt conveyor 12 at the same time as it lands. When this conveyance is completed, the pneumatic cylinder 52 is energized again to provide assistance. The tilting and raising of the crosspiece member 60 and the horizontal rise of the crosspiece member 32 are started, and the next corrugated sheet 10 is awaited to be dropped and supplied, and this cycle is repeated thereafter. In the present invention, in the descending stroke, although the auxiliary crosspiece member 60 starts descending in synchronization with the crosspiece member 32, the former descends faster than the latter and settles below the upper surface level of the crosspiece member 32. The timing at which the rear crosspiece member 32 descends from the upper surface level of the roller member 18 is important, and this timing is set to an optimum value depending on the shape design of the bell crank 38. Further, in this embodiment, one bell crank 38 connected to the crosspiece member 32 and the auxiliary crosspiece member 60 is used in common, but bell cranks with different arm angles and arm dimensions are prepared, and It goes without saying that the member 32 and the auxiliary beam member 60 may be made to share the responsibility exclusively.

得られる。As described above, in the present invention, when receiving falling plate-like sheets, the auxiliary crosspiece member is tilted upward and brought closer to the open end of the belt conveyor, thereby avoiding the influence of air resistance due to the head difference, and delivering a predetermined number of sheets in an orderly manner. In addition to making it possible to stack sheets, the stacked sheets can be transferred horizontally onto the roller member, so the sheet stack will not be biased in the conveying direction, thus facilitating smooth processing in the next process. is achieved. Moreover, since the drive mechanism for carrying out the present invention is relatively simple, it is easy to manufacture, and the manufacturing cost is also low, which is a secondary advantage.
