The unloaded workpiece a is introduced into an endless belt device (1) provided in front of the workpiece and is fed further forward.

The belt device +11 has a pair of upper and lower lobe belts (2
Both bells (2&) (2b) rotate in the direction of the arrow in conjunction with the driving mechanism (3), and the front end of the upper bell (2a) is movable up and down. The cylinder mechanism +41 allows the lower bell (2b) to be moved toward and away from the lower bell (2b) in response to the feeding of the workpiece a, and the workpiece a is introduced between both belts, and then the workpiece is brought into contact with the belts. Make sure to send a forward,
The feeding and hanging speed of both belts is faster than the feeding speed of workpiece a from the bag making machine. Therefore, workpiece a that is introduced sequentially by belt transfer is separated from the following one, and the difference in speed causes the workpiece a to The upper and lower belts for transporting workpieces a in each row are connected to the fixed front plate (5) in the center.
The belt device fZ (
There are guide wall plates (7) (7) on both sides of the upper surface connected to the tip of 11.

9+, and the support stand (6) was moved up and down according to the guide rod α4 in conjunction with the motor az installed on the fixed machine stand. That is, the workpieces a sent from the bag-making machine are counted by an appropriate counter WI mechanism α, such as a photoelectric device, and the shifter a21w is activated by a signal detected every 10 sheets, and the workpieces are transferred to the support stand. (6) is lowered intermittently little by little from the upper limit position of the solid line in Figure 2, and when this lowering operation has been repeated 9 times, the support base (6) is at the lower limit position shown by the chain line in the figure. I made it.

At the rear of the lifting support table (6), a rack and pinion device 1ian interlocked with the cylinder mechanism α1 is provided between the standby position and the upper surface position of the workpiece a loaded in each storage section (91 (9)) of the support table (6). Movable support base plate (I7) that moves the

6), the movable support base plate αη, and the pushing mechanism constitute a constant workpiece loading device, and when the support base (6) is at the lower limit position as described above and 100 workpieces a are stacked, The cylinder mechanism α is moved by the counting signal, and the rack and pinion device (LE9) moves the movable support plate θη from the standby position to the upper surface of the stacked workpieces a in each storage section (9) and the next stacked workpieces. The cylinder mechanism (
11 reciprocates the pushing plate Q81, and by its forward movement, both station capacity parts (91 (91) of the laminated workpiece a in 91
is fed forward, but during this time workpiece a continues to be fed continuously, so the 101st workpiece and subsequent works are loaded on the movable support plate (17), and
It is reliably separated from the 100-sheet stacked workpiece above. The laminated workpiece a sent out from the support table (6) by the pushing device is transferred onto the moving table top (to be described later), but a signal when the movement is finished activates the motor (2) and the workpiece is emptied. The support base (6) is moved upward at the full upper limit att, and in synchronization with this, the cylinder mechanism α4 is operated to return the movable support base plate αη from the advanced position to the standby position.The support base plate (lη is formed to be narrower than the width of workpiece a, and the fixing plate (
In order to advance and retreat by pushing through the inside of the 2D slit, the 101st and subsequent 10Wi works loaded on the support plate (17) during the backward movement are swept away by the slit of the fixing plate at+ and transferred to the support plate (6). ), and the works a are sequentially stacked on the upper surface thereof, and when the number of works a reaches 100, the same operation as above is repeated.

The moving table (a) has guide wall plates (2 (2) It is equipped with a partition wall plate (231), and a support plate (2) for supporting the stack of workpieces to be fed is provided in front, and this is moved along the arrangement direction of the workpieces a by a cylinder mechanism. A pushing mechanism @ using a cylinder device is provided so as to be perpendicular to the direction of movement of the guide rod (c), and the moving platform, the cylinder mechanism (c), and the pushing mechanism (5) move the laminated workpiece a. The entire transfer device was configured.

An automatic binding device @ is provided in connection with the transfer device.

The automatic binding device M (2) is a known device that pulls out a reel of binding tape and wraps it around the object to bind it. Forming a working part Gυ, a pushing mechanism (27) of the transfer device
was placed opposite the binding work section 0υ.

In this way, the two laminated works a are moved from the support table (6) to the transfer table (
b) After being transferred onto the top, the moving table is moved in the direction of the arrow in Fig. 1 by the cylinder mechanism (c), and the laminated workpiece a is transferred to the transporting mechanism (27) and the binding device C. The stacked workpiece a is placed in between and pushed by the pushing mechanism (5) to the binding work part c3υ to perform the binding operation Q', and then the workpiece a is further moved in the same direction by the arrangement pitch on the moving table e2G'. Then, the pushing mechanism (3) sends the υ second laminated work a to the binding work part C31) and bundles it, and then returns the moving table (2G') to the initial position corresponding to the support table (6). and prepare for the next operation.

In this way, the workpieces a, which are sent out from the bag making machine in two rows of one sheet at a time, are sent by the endless belt device (1) to the storage sections (9) (9) on the lifting support stand (6) at the upper limit position. The workpieces are pushed in and loaded, and the support table (6) is fully lowered every predetermined number of sheets, and the workpieces a'z are sequentially loaded, and at the lower limit position, the support table (6
), the movable support plate (tη) advances between the top surface of the laminated workpieces and the 101st workpiece, and the workpieces A that are continuously fed from then on are stacked on the movable support plate. Two of the 100 laminated workpieces a loaded on the support stand +61 are transferred to the top of the moving table by the pushing plate at the lower limit position, and the empty elevating support stand is loaded on αη. (6) is moved upward from the lower limit position to the upper limit position in preparation for the next loading operation, but when it reaches the upper limit position, the movable support base plate α7) retreats from within the support base (6) to the standby position. Since the workpiece a loaded on the upper surface is left on the support table (6), the workpieces a discharged from the belt device (II) are sequentially loaded on the upper surface of the support table (6).
When the movable support platform αη reaches the upper surface of the
00 laminated workpieces a are separated and the above-mentioned operation is repeated.

At the lower limit position of the support table (6), the laminated workpiece a, which has been moved onto the moving table by the end of the pushing plate, is sequentially sent to the automatic bundling device (to) and bound by the movement of the moving table (21). - is returned to the original position to prepare for the next operation, and thus the workpiece a sent out from the bag making machine one by one is 100 pieces in sequence.
The sheets are stacked and separated and bundled.

The automatic cycle from feeding to stacking and bundling of the workpieces a is performed continuously with smooth timing using signals from the counter aa and a limit switch or a proximity switch (not shown) provided at an appropriate location.

The above is an example of the case of the second invention in which the beam beams a are sent out in a plurality of rows, and a transfer device is interposed between the automatic binding device and the fixed number of workpiece loading device mainly consisting of the lifting support table (6). The feature is that it is compatible with the bundling work of laminated workpieces a arranged in multiple rows, but it can be sent in one row! 7. In the first invention, which targets the workpiece a to be taken out, as shown in FIGS. 6 and 7, the transfer device in the second invention is omitted, and an automatic binding device is directly installed on the workpiece loading device. A constant number of laminated work pieces a'z are arranged in series and stacked on the lifting support table (6).
