Abstract

PURPOSE:To reduce labor and improve the efficiency of work, by providing an automatic feeder, which functions so that every appropriately divided quantity of sheets automatically stacked from a pallet are transferred to an automatic true-up machine in which the sheets are trued up to a normal state before they are sent out to a next process. CONSTITUTION:When a sheet feeder is started after stacked sheets A are put together with a pallet P on a vertically movable table 31, the table is elevated by the height of stacking for one time of division and sending-out. After that, a movable member 16 supporting a clamp is moved forward by the action of a cylinder 17 so that a scooping member 22 is inserted to the prescribed part of the stacked sheets A while the member is lifted and moved forward. Subsequently, a hold-down member 25 is moved down so that the end of the stack of the sheets A is pinched between the hold-down member and the scooping member 22. After the table 31 is moved down, a roller conveyor 4 is driven so that carrying rollers 48 are moved in under the divided stack A' of the sheets and support them. After that, the conveyor 4 is moved backward and a transfer mechanism 10 is moved rightward so that the divided stack A' of the sheets are transferred onto a sheet true-up machine 50.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) This is a defect regarding a sheet feeding device for paper or the like.

The construction of the apparatus of the present invention constructed in this way
First, before starting work, place the table (3I) in the elevating mechanism (3) between the main frame +2 + +21 at the lowest position, and stack printed sheets, for example, on the table (3I). Place it together with object (A) and baren) (p). Next, the stacking size for one divisional feeding is set by the detection section, and the driving section of the lifting mechanism (3) is operated according to this. Thus, a signal to start operation is given to the control unit of the supply bag @(1), tJl,
First, the drive motor Qω of the lifting mechanism (3) operates,
Due to the action of the drive mechanism, the J-axis rotates, so the chain wheel opening 31 f33) on the axis d is hung on the endless chain 3, The stack of sheets (A) mounted on the table top is raised to the required height.

This one seedling clamp a structure) is a carrier frame UL! is the central space r of the frame (11) at the general position 17f.
s (s 1131 is in the retracted position and the roller conveyor +4) l-1: The four support rollers are in the retracted position ω (see Fig. 6).

Next, when the clamp supporting moving body J (operating air cylinder F17 of 3) Jη is activated and moving the moving body (3) forward, the cam 4 attached to the 11th side in the narrow part of the carrier frame (1) is exposed to air. The clamp operation plate is lifted up via the cam roller 6, and during this operation, the tip of the scooping ring of the clamp mechanism is shaped like an air gun with a sharp tip. Ki
While injecting Ia from the co-supplied pressure dividing nozzle b, the pressure is inserted into the predetermined position of the treated sheet layer stack 8 (4) (or, at the same time as it is inserted, re-air is injected), and this air gun 0,
In other words, as the scooping piece (2) moves forward, it moves diagonally upward, causing the air gun nozzle! The insertion part is expanded by the air blown out from 2b, and the layer above it is separated, and the upper layer is lifted up by the scooping piece Q as shown in FIG. At the same time, the presser piece operating air cylinder □□□ operates to lower the presser piece %r and scoop the scooping piece Q.
At step 4, lift up the divided sheet layer and clamp the local end (see Figure 8).

After clamping the divided sheet Mω in this way, the clamp supporting moving body is operated backward by its operation ring Uη, and the separated sheet layer ω clamped at the center of the end is pulled. Both sides of the lamp part are recessed into the lower part of the carrier frame (11).
(see Figure 9).

After that, the driving part of the lifting mechanism (3) is reversely operated to lower the table @0 by a certain distance, and as shown in FIG. (4) A large gap will be created between the top surface and the supporting roller part by driving the roller conveyor (4) with respect to this gap 0 part, and The separated sheet layers are operated so as to be supported on the lawns of the conveyor (see FIG. 11).

When the required amount of sheet layers ω is divided in this way, the carrier frame (11) is caused to move back to the guide rails (5) (5), and in synchronization with this, the roller conveyor (
4) also retreats the support roller decoy part. Then, the divided sheet layer ω, whose one end is clamped by the clamping mechanism yaw, is supported by the roller conveyor (4) and conveyed to the front part between the main body frames +21 and +21, and the clamped portion is conveyed to the front part of the carrier frame (11). As the conveyor (4) part, which supports the other parts on the entire surface, moves to the middle position of the supporting roller 11, it gradually retreats downward (see Fig. 12), and eventually the carrier frame lli When the rear end of the divided sheet layer (A) moves away from the support roller 14111 of the roller conveyor (4), it first moves onto the table extension 0 of the automatic paper alignment machine located at the lower front of the machine. The trailing edge between the sheet layers is received.

At this time, the table system of the paper aligning machine is raised and pulled out so that the divided sheet layer ω is received with an appropriate height, and when the carrier frame (11) is finally retracted and reaches the home position, the presser plate When the clamping operation is released by raising the opening, the sheet layer ω is supported on the table 00 by its own weight (see FIG. 13). Therefore, the divided sheet layer ω
The paper aligning machine that receives the sheet operates to correctly align each sheet of the divided sheet layer ω that has been misaligned. If the above-mentioned receiving operation is performed while the paper aligning machine is activated from the beginning in a fixed position, the sheet layer ω will be vibrated at the same time as it is spread and placed on the table when it falls. Therefore, the alignment operation can be performed quickly.

Then, the divided sheet layer, which was divided into the required amount and pulled out in the above manner, was transferred to the paper aligning machine, and then the carrier frame (11
) and the attached clamp structure move forward to the initial position and wait, and the sheet stack to be processed (A
t is increased by the required amount by the operation of the elevating mechanism (3), and thereafter, the operations of dividing the sheet into the required amount in the above-mentioned order, pulling it out, moving it to the sheet alignment machine, and processing it are repeated in sequence.

In addition, when stacking the divided sheet layers one after another on the table 05 of the paper aligning machine Shoshu, in order to prevent the previously aligned sheet layers from shifting, the table value l is set to the sheet layer presser roller. The operating mechanism may be provided as an accessory, and the operation mechanism may be used to hold down the previous sheet layer until the divided sheet layer is received on the table.

In addition, when dividing the sheet laminate (4) to be processed by inserting the air gun
Lifting and lowering mechanism (3) between 21 and 21, a paper presser having a presser rad (8') at the lower end which applies a downward thrust with a spring mechanism interposed in the middle part as shown in Fig. The paper presser (8) automatically presses the upper half of the sheet stack with a moderate thrust when the sheet stack (gradient) is lifted, and prevents misalignment due to split insertion using air gun 0. There are seven things you can do to prevent this from happening.

Furthermore, if necessary, a vertically movable or fixed sheet layer edge correction plate can be provided at the upper rear position of the lifting mechanism to prevent the sheet from shifting due to the thrust when the air gun is inserted. It will be useful.

When bringing a stack of sheets to be processed onto the table of the lifting mechanism, lower the table to the lowest position and place the palletized material from the rear of the main frame using a transporter such as a forklift. Bye. In addition to the engine drive, it is also possible to use a bell seat drive to drive the clamp transfer mechanism. Furthermore, each operating cylinder in the clamp transfer mechanism may employ an actuator such as a hydraulic cylinder or an electric cylinder in addition to the air cylinder.

(Effects of the Invention) As described above, according to the present invention, if the amount of divided sheet layers for one time is set in advance, the stack of sheets to be processed can be made by simply performing the operation start command -8- of the apparatus. The sheets are automatically divided and taken out one after another, and by combining this with an automatic sheet aligning machine, the required amount of sheets can be correctly aligned and fed to the next work process, all by 4a machine operation. In particular, when handling sheets whose surfaces have been processed such as printing, the first step is to move the sheet layer horizontally after dividing and place it on the table of the paper aligner, and then to move the sheet layer in the opposite direction while clamping one end of the required sheet layer. Drop it onto the table from the side free end so that each sheet is spread out.
They were moved onto a table so that alignment operations could be easily performed. Then, when dividing the required amount of JETNOZU 4 and moving it to the paper alignment machine, the center end is clamped almost simultaneously with the division using an air gun, and both ends on the clamp side are supported to keep it in a stable state. The roller conveyor is used to support the divided sheet layers until just before they are transferred to the paper leveling machine, which simplifies the sheet layer feeding work that previously required manpower, reducing labor and improving efficiency. We were able to make it possible to implement it.

It goes without saying that the feeding device of the present invention can also be used for feeding operations that do not require paper alignment operations, and in this case, instead of the paper alignment machine, a conveyor whose table can move up and down, or an intermittent Combined with a conveyor with a traverse function,
It is possible to supply the required amount of stacked sheets to the desired location.

Further, the work order in the above-described embodiment is merely an example, and it goes without saying that the work order can be changed as necessary.
