Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet supplying device for paper, etc., which is combined with an automatic paper alignment machine to efficiently and automatically divide a large number of sheets of paper and supply them to the next processing step. .

Conventionally, in order to use a cutting machine to cut large sheets of paper that have been printed or otherwise processed into the required dimensions, the printed or other processed paper (sheets) are laminated as appropriate and then cut. Before starting this process, each piece of paper must be adjusted so that there are no misalignments before it is sent to a cutting machine and cut to the required dimensions, so it is always necessary to cut large sheets of paper during the process.
It is essential to align the rounding, and this was done manually, but due to the large weight of the paper layers handled, it was hard work, and the work efficiency was also low. A machine has recently been developed and is in practical use. However, even if this automatic paper alignment machine were developed, printed paper would still have to be stacked on pallets to be transported from a printing factory to a cutting or bookbinding factory. Therefore, the weight stacked on this pallet.

It is inconvenient that it takes a lot of labor to transfer the processed paper to the alignment machine, and to divide it into appropriate amounts and place it on the table of the alignment machine also requires a lot of labor. In particular, stacks of paper are quite heavy, so work that involves lifting and lowering them frequently requires considerable physical strength, resulting in severe worker fatigue and the need to do this for long periods of time. People often suffer from lower back pain when engaged in such work, which is unfavorable in terms of occupational safety and health.

The present invention solves certain problems and automatically divides the stacked sheets into appropriate amounts from a pallet, transfers them to an automatic aligner, and after properly aligning them, sends them to the heating process. The purpose is to provide a supply device.

That is, at the beginning of the process, an elevating mechanism is provided at the rear intermediate position between a pair of frames arranged in parallel at appropriate intervals, and the stack of sheets to be processed is placed thereon and raised by the required amount.
At the upper rear part of the elevating mechanism, there is provided a feeding mechanism equipped with an air gun that divides and feeds the laminated material to be exposed when moving forward using guides attached to the frame at both ends, and the front part of the frame faces the feeding mechanism. is provided with a clamp transfer mechanism that is operated by a drive mechanism built into both frames so as to reciprocate from the receiving position of the stack of sheets to be processed forward over a required distance, and a clamp transfer mechanism is provided between the clamp transfer mechanism and the delivery mechanism. The receiver is supported at both ends by the frame so that it can move back and forth over the required distance, and rollers are installed on the frame, and a paper presser mechanism is attached to the lower part of the protruding front of the frame.The end alignment plate is attached to the side, making it possible to move it out of the device. This is a laminated sheet feeding device that can accept a paper aligning machine.

Hereinafter, one embodiment of the apparatus of the present invention will be described in detail with reference to the drawings.

A feeding mechanism tlcI for the divided sheet layer is provided above the rear section between the pair of frames tel+21, and the feeding mechanism tlcI is provided on the inner surface of both frames fil (21) in an appropriate section from the rear to the front. Guide with uphill pressure at inclination angle (+
1), each end is supported by this guide (6) part, and a splitting operation beam 1oj is erected between both frames, and this splitting operation beam (11) is shown in Fig. 1 at the front lower part of the center. It has a tapered outer shape with a pointed tip and a tapered taper from the base to the tip, and a hose I is installed from a separate position inside the hose to supply compressed air, and the pressurized air is discharged through the tip nozzle U6. An air gun U4 is mounted on both sides of the air gun U'4, and one or more divided sheet layer end pushing pieces 041 are attached to each side of the air gun U'4.
It is arranged so that it hangs down so that it touches only the divided sheet layer.
This divided operation beam 1uj is moved back and forth by hydraulic cylinders (which may be electric cylinders or gear-driven linear actuators) at both ends.

The upper part of the 7-frame Ill tel is made horizontal, and the front half is formed to protrude from the leg part (21), and from the forwardly protruding tip part of the frame +!l (21) (→The receiving section is equipped with a clamp transfer mechanism for carrying out the divided sheet layer that is movable in the front and back direction in the section from the receiving end to the vicinity. This clamp transfer mechanism is installed on the inner surface of both 7 frames 121 + 21. A chain chain is wrapped between the chain wheel (26) and the chain wheel (26) arranged at the required position on the upper part, and each end is attached to the chain wheel (2), and the clamp moving frame (2) is attached to both frames. This clamp moving frame (2) is constructed between a support piece (goods) for supporting the end of the divided and fed sheet layer, and a support piece (goods) which is opposed to this and is pressed from above by a fluid pressure actuated cylinder C2IK. The is equipped with a pressing piece to which force is applied, and consists of the following: The drive of the transfer chain (6) is transmitted from the deceleration motor fin to the shaft of the chain wheel at. It is designed to drive in forward and reverse directions.

In addition, between the clamp transfer mechanism and the delivery mechanism, one or multiple wooden holders are equipped with rolls (6) on both frames.

Frame 12) of the feeding device fil thus made (2)
At a lower position of the arm portion protruding forward from the front support fI4112'l, there is a known automatic structure.

This self-excited paper aligning machine has a structure in which a table @0 equipped with an air film forming mechanism is supported at the center of the lower surface and is tiltable, and a vibrator is added to the table so that the table can be moved up and down. And Fi, jI on one side of the table @υ
A sheet layer presser piece with a lever link type and a presser roller at the tip is attached to the X-mounted sheet 4 and operated by a hydraulic cylinder (2).

The relationships are such that they operate sequentially in a predetermined order.

The operation of the device of the present invention constructed as described above begins with the lifting mechanism (3) between the main body frames +21 and +21.
) The amount of processed sheet laminate (4) in which printed sheets are laminated on the table product ball is $11 L, and then the size of 81 layers for one divided feeding is set in the detection unit. Then, if you give a start signal to the control unit of the supply bag @It),
First, the lifting mechanism 1B1 moves the table to a predetermined height (
3') Raise the stack of sheets (4) placed on top. At the same time, the clamp moving frame of the clamp transfer mechanism (7) moves to a position just before the Iffff music of the stack of sheets to be processed (4) and waits. (See Figure 3).

Next, when the fluid pressure actuated cylinders of the sheet layer delivery mechanism +101 operate simultaneously to advance the dividing operation beam (11), the air gun 0'4 supplied at the same time will cause the air gun 0'4 to be applied to the sheet stack to be processed. When inserted into a predetermined position, the sheet layer is divided at the insertion part by the air ejected from the nozzle A4, and the upper layer is divided by the end pushing piece 041 of the division operation beam ill which moves forward together with the air gun O. The receiver of the clamp moving frame (c), which waits the (g) forward from the top of the stack, feeds the front end into the plate (
¥; see figure 4). This clamp moving crocodile frame inner receiver is a sheet layer divided on one side (when the sheet is fed in, the splitting operation beam itH of the feeding mechanism + 101 has both ends guided by If
The more the air gun moves forward while being guided by the
In addition, the upper holding piece on which the sheet m < d end is inserted is lowered by the action of the hydraulic cutoff cylinder (company), and the receiving piece is clamped by the piece e2~ and the presser Kataoka. do. At this point, the receiver roll (6) has just split the sheet layer (
The A receiver is located below the clamp moving frame (2) which is in the insertion position (see figure $3). When the ends of the sheet layer (A) divided by the support piece and the presser piece of the clamp moving frame (2) are clamped, the elevating mechanism (3) is temporarily lowered as appropriate. During this time, the split operation beam (11) with the air gun smell retreats and returns to its original position, and the
) is formed between the descending processed sheet stack (A) and the divided sheet layer ω and is caused to enter the nine gaps. Then, this support supports the rear half of the υ divided sheet layer member by the roll (6) (see Fig. 5). In this state, the clamp transfer mechanism
At this time, the clamped sheet layer (the latter half of I5 is moved while being supported by the roll (6), and the roll (6) also advances to its original position. This allows the divided sheet layer ω to be transported forward from above the sheet stack to be processed (A) without sagging during feeding.

Therefore, just before the clamp moving frame (c) moves forward the most, the rear end of the divided sheet layer ω separates from the receiver roll (61).
Since the paper alignment machine Cheagle@11 is located just below it, the sheet layer (A) is placed on this table 1 first.
The rear end of the holder is stopped. At this time, the table elO of the waste paper aligning machine is raised and pulled out so that the divided sheet layer ω is received with a suitable height, and then the clamps are moved to 1.
When the frame wire moves forward and reaches the fixed position, the suppressing piece is raised and the clamp operation is released.
0 will be paid and paid. Therefore, the paper aligning mechanism that receives between the divided sheet layers operates to correctly align the sheets on the divided sheet layer surfaces that have been misaligned. The vibration operation of this paper alignment machine is activated from the beginning in the fixed position, and if the above-mentioned receiving operation is performed in the repulsion state, when the sheet layer ω falls, it is spread and placed on the table, and at the same time it is vibrated. Therefore, the alignment operation can be performed quickly. And this-
If the paper is to be transferred one by one to the next step, the paper alignment machine may be moved to the required position. In addition, multiple division Ji
When stacking and aligning the layers and transferring to another process, move the clamp moving frame (to) to the original position and remove the workpiece from the table front stop of the lifting mechanism (3), which has been raised by the required amount as described above. The sheet P4ω is divided into a predetermined amount of sheets and separated into the front part in the above order by the operation of the clamp transfer mechanism.
is pulled out, and before this divided sheet layer is transferred onto the paper aligning machine, the sheet layer presser attached to the waste paper aligner i is tilted down by its operating fluid pressure-operated sill.
Hold the stacked sheet layer (A5 edge) first with a roller to hold it in place, and then receive the next divided sheet layer on top of this to prevent the previously aligned sheet from shifting and stack. The second sheet layer is held down until it has finished falling, and then the holding operation is released to ensure that all the sheet layers are properly aligned (see Figure 9).
Then, the operations are repeated in the above order until the required amount is achieved.

In addition, when bringing the stack of sheets to be processed onto the table of the lifting mechanism, the table of the lifting mechanism must be lowered to the lowest position [IC, 7. All you have to do is place it there. Further, the clamp transfer mechanism and the drive IF+ mechanism which follows the movement of the roll can be operated using a belt drive or a wire group, in addition to the chain drive of the above embodiment.

As described above, according to the present invention, if the amount of divided sheet layers for one time is set in advance, the operation of the apparatus can be started easily.

Just by issuing a command, the stack of sheets to be processed will be automatically removed.

), and by combining this with an automatic sheet aligning machine, the required amount of sheets can be correctly aligned and fed to the next process, all by mechanical operation. In particular, when handling sheets whose surfaces have undergone processing such as printing, instead of moving the sheet layers laterally after dividing and placing them on the table of a paper aligner, one end of the required sheet layer is clamped on a pillow seat, and the opposite end is Since it is operated as if it were dropped from the top onto the table, each sheet leaves a tbtt-like trace at this time, and then the clamp is released and the sheet layers are all transferred onto the table, making it easy to align them. This allows work to proceed quickly. Therefore, even when arranging Jiko paper in the past, it required manual labor to align the sheets.
The supply of equipment no longer requires any manpower at all, and the economy and efficiency of the labor force can be improved at the same time.

It goes without saying that the feeding device of the present invention can also be used for feeding work that does not require paper alignment, and in this case, it can be combined with a conveyor whose table can be raised and lowered instead of the paper alignment machine. This makes it possible to supply the required amount of laminated sheets to the desired location.
