Description of the Related Art Generally, in the process of molding a concrete block, an iron plate pallet, which is a member of a mold, is placed on the lower surface of a mold box of a predetermined molding machine to raise a lifting platform below. No, after the molding process, the pallet is lowered with this molding block placed and discharged in a separate direction. As a pallet supply device for a lift table located directly below a conventional molding machine, for example, as shown in FIG. 13, a plurality of pallet feeders are provided at a standby position of a lift table a and on a feeding rail b installed on one side of the stand. Pallets c are sequentially arranged in abutting arrangement, and a replenishing pallet c ′ that has dropped from the uppermost position and is on standby in the pallet c is moved by a fixed stroke of a single hydraulic cylinder d. A method is adopted in which only the earliest pallet c that is sequentially pressed (for one sheet) is pushed to the set position on the elevating table a by pushing with e.

る。However, as described above, a plurality of pallets c are pressed from the rear by the iron feeding rail b.
In the loading operation in which the top pallet is slid on and the first pallet is loaded on the lift a, it was not possible to reliably position one pallet. That is, the iron plate pallet itself is preliminarily coated with oil in order to improve the separation of the molding block placed on one surface (upper surface). Moreover, the pallet is replenished in the drop replenishment section set on the rear side of the feed rail, and the replenishment pallet is dropped from above by the well-known dropping means at any time to make a standby by stacking a plurality of sheets on the feed rail. Due to the transfer of the oil from the pallet, the oil unavoidably spills on the lower surface of the pallet, and the oil also adheres to the feed rail, making it slippery. For this reason, the rearmost pallet is pressed and the feeding rails are sequentially slid so that only the earliest pallet is placed on the rail part b'which is connected to the lifting table a by the ejecting operation and which is obtained in the preceding step. It was difficult to load the molding-completed pallets in turn while ejecting them, and it was not possible to reliably position the pallets for loading, which often resulted in overruns. Of course, if the pallet is lifted in the misaligned set state, it may inevitably collide with the guide end of the mold box.

Further, the space behind the advanced pallet at the rearmost end is used as a pallet replenishing space for dropping from above, and in order to facilitate the fall of the replenishing pallet, the drop receiving gap h must be set at the front and rear positions of the pallet. The pallet retreating operation that separates from the lifting platform side,
The locking claw g of the connecting rod f, which is separately provided on the pressing carriage e, is moved backward.

ができず、能率向上が図れなかった。As described above, there is a limit to the speedup in the type in which the pallet is fed out by simply sliding (sliding) on the feeding rail (if the pallet sticking out / transporting speed is increased, the sliding movement of the feeding rail due to oil adhesion will occur). Due to this, the loading position on the elevating table shifts more and more, so it is the current situation that feeding is done at a slow speed), and thus the time for the concrete block molding cycle (1 process) cannot be shortened, resulting in efficiency. I couldn't improve it.

な位置決めがなされる。With the above-mentioned structure, the first pallet among the plurality of pallets arranged on the feed rail is brought into contact with the pallet discharging / receiving claw piece at the end of the pallet guide arm portion projecting from the transfer frame. Then, the pushing step portion of the pressing body facing the rear end of the rearmost supply pallet is provided with a drop receiving gap. Here, when the earliest pallet is fed out and carried in to the lift table, the second gap adjusting cylinder mounted on the transfer frame is first operated to advance the pressing body to close the drop receiving gap at the front and rear positions of the supply pallet. . After that, the first cylinder for pallet feeding, which is the main cylinder, is operated to advance the entire transfer frame body by a certain stroke. All of the pallets slide on the feed rail, and only the earliest pallet is fed to the lift. In this case, on the back surface (front surface) of the claw receiving piece that receives the earliest pallet, the molding completed pallet on which the previously descended blocks are placed is pushed out and replaced. That is, since the new pallet to be loaded on the lift table is forcibly guided by the receiving claw piece, reliable positioning can be performed without overrun.

となる。At this point, a new pallet 10 is carried into the lift 16 based on a pallet supply signal corresponding to the concrete block forming process of the block forming machine 17. In this case, first, the pressing body 8 mounted on the rear part of the transfer frame body 3 is mounted.
By operating the second gap adjusting cylinder 9 provided in the pressing body 8 and moving it forward a little by feeding out the rod 9a, and pressing the replenishing pallet 10a by the end face of the pushing step portion 8a of the pressing body 8, the replenishment is performed. The drop receiving gaps h, h at the front and rear positions of the pallet 10a are closed. At this time, the end of the earliest pallet 10 is in contact with the inner surface 12a of the pallet discharging / receiving claw piece 12 at the end of the pallet guide arm 11 and the entire pallet group is transferred to the transfer frame 3
It is in a state of being tightly housed (sandwiched) inside (see FIG. 11). At this time, since the pressing body 8 is slidable on the pair of support shafts 7 and 7 mounted in parallel on the side of the transfer frame body 3 serving as a base, the pressing body 8 obtains a smooth horizontal transition and is a kind of ruler structure. Thus, the pallet 10a for replenishment can be pressed without shaking, and the second cylinder 9 itself can be used as a small cylinder.

12,図9参照)。After that, when the pallet feeding first cylinder 6 is actuated and the rod 6a is fed out by a constant stroke, the transfer frame body 3 integral with the end of the rod 6a rolls on the support rail 4 on the machine side. Go forward through the car 5. The stroke of the rod 6a of the first cylinder 6 is set to the distance that the inner surface 12a of the pallet discharging / receiving claw piece 12 at the end of the pallet guide arm 11 reaches the tip edge of the lift table 16. For this reason, a group of a plurality of pallets 10 is forcibly forcibly fed by the feed rail 1 while being sandwiched between the pallet discharging / receiving claw piece 12 and the pressing body 8.
Slide the surface, and only the earliest pallet 10 is the lifting table 16
The transfer rail 1 is moved to the receiving rail portion 19 on the same surface, and the position at which the transfer frame body 3 is stopped is aligned with the end of the pallet discharging / receiving claw piece 12 and the end of the elevating table 16 so that reliable carry-in positioning is performed. . That is, a new pallet is loaded at speed (see FIGS. 12 and 9).

接衝することなく通過し得る。In this way, the new pallet 10 carried into the lift table 16 is moved to the mold box (block box) of the block molding machine 17 directly above as the separate lifting means 20 provided with the lift table 16 is lifted. A predetermined forming process is performed by facing the (not shown). When the lift table 16 is raised, the pallet guide arm portion 11 that has been fed out retreats along with the transfer frame body 3 by the return movement of the pallet feeding first cylinder 6, but in this case, the pallet guide arm portion 11 pallet is moved. Since it is set to be smaller than the inward constriction formed on the base portion 16b of the lifting / lowering table 16 that can increase the lateral projection amount of the discharging / receiving claw piece 12, when the pallet discharging / receiving claw piece 12 is retracted, the base of the lifting / lowering table 16 is set.

する。As described above, in the pallet feeder of the concrete block molding machine of the present invention, the most advanced pallet among a plurality of iron plate pallets lined up on the feed rail is provided in the pallet guide arm portion of the transfer frame. The pallet discharging and receiving claw piece receives the last pallet by the pressing body mounted on the transfer frame, and the pallet is sandwiched between the transfer frame and the two pressing cylinders. The supply pallet formed on the last pallet is filled with the falling gap and the slide of the pallet group on the feed rail is forcibly moved by gripping the frame body, so regardless of the oil-attached feed rail. In addition to promptly carrying in one piece to the elevator,
Reliable positioning without overrun. That is,
Speedy loading of pallets into the lifting platform is possible,
It is possible to reduce the time required for one step of block molding (for example, in the conventional pallet feeding operation that directly pushes with a single cylinder, it takes more than 2 seconds to avoid overrun on the lifting platform. However, if the forced transfer of the present invention is used, it can be shortened to within 1 second, which means that if one cycle of the block molding processing time is 12 to 3 seconds, it is increased by 10 to 15%. Become). Moreover, since the transfer frame and the pressing body have a simple structure in which they move by a cylinder, they have a robust structure and do not cause failures or damages during use. Since the device is mounted on the body, the entire device can be compactly assembled and can be incorporated in the conventional pallet feeding device section.
