The operation of the present invention as described above will be described.

First, the forklift 2 of the lifter 1 is lowered to the floor, and the empty forklift 7 is placed on the forklift 2 and the forklift 2 is raised. When the sensor is raised to a predetermined position, a detection sensor for detecting the signal sends a signal to the control device 5 to stop the driving of the brake motor 4. In this state, the empty box 8a is moved to the empty box loader 6. In turn, the piston of the upper cylinder 64 of the empty box loader 6 is immersed so that the upper pressure zone 641 is moved to both sides, while the lower cylinder 65 of the lower cylinder 65 The piston is in a state in which the lower support port 651 supports the bottom of the empty box 8a as it is in a state of appearance, and the plurality of empty boxes 8a are stacked in multiple stages, and then the upper cylinder 64 The upper pressure zone 641 by popping up the piston So just hold the bottommost empty boxes stacked on top. The above operation is performed by the operator operating the function selection button of the control device (5).

When the start button of the control device 5 is operated on in the above state, the lower cylinder 65 of the empty box stacker 6 operates first to retreat the lower support hole 651 to both sides so that the empty bottom The box 8a is released so that the empty box falls on the transport cart 7, and then when the lower cylinder 65 is operated to its original position, the upper cylinder 64 is operated to move the upper pressure strip 641 to both sides. When the empty box held by the retracting operation is released, the empty boxes 8a put into the empty box stacker 6 are guided by the vertical portion 71 and the angle guide 63 of the transport cart 7. Falling down is supported by the lower support hole 651, when this state is the piston of the upper cylinder 64 is the appearance of the operation of the upper pressure strip 641 to hold the second empty box (8a) from the bottom. .

When the preparatory operation as described above is completed, the single-piece processing machine starts operation and the processed products P which are automatically continuously discharged one by one through the discharge chute S are counted by the count sensor and stored in the empty box 8a. Meanwhile, while the workpiece P is dropped into the empty box 8a as described above, the brake motor 4 of the lifter device 1 responds to the operation signal of the control device 5 as described above. To lower the forklift 2 slowly so that the transport trolley 7 loaded on the forklifter 2 is lowered by one height of the bin box 8a. The space between the box 8a and the discharge chute S is to be secured in advance.

The above-mentioned operation of accommodating the workpiece P while counting a predetermined quantity and the operation of lowering the forklift step by step by the height of the empty box 8a are performed together without stopping the machine processing machine. This is to continue to operate and to be able to increase the output of the workpiece (P) by being able to discharge while processing the workpiece (P) continuously.

As described above, the empty box 8a receiving the processed product P discharged from the discharge chute S is lowered to secure a space for the next empty box, and the predetermined quantity is stored. If the control device 5 that detects the signal of the count sensor operates the lower cylinder 65 of the empty box stacker 6 so that the lower support hole 651 releases the lowermost empty box 8a. Is dropped down to receive the processed product (P) discharged from the discharge chute (S) is stacked on the seal box (8b) in which the processed product (P) is fixedly received, the empty box (6) in the empty box ( 8a) falls within the short time that the workpiece (P) is continuously discharged from the discharge chute (S), so that the workpiece (P) can be continuously received in the empty box, while the empty box loader (6) When the empty box falls, the discharge chute (S) After the retreat to the back, the empty box is placed on the seal box (8b: the fixed amount of the workpiece) that has received the workpiece (P) correctly, and then configured to move forward to its original position. It is comprised so that it may fall safely in the box 8a.

After dropping the lowermost one of the plurality of empty boxes stacked in multiple stages in the empty box stacker 6, the lower cylinder 65 is reactivated to return the lower support hole 651 to its original state. Subsequently, when the upper cylinder 64 is operated to retreat the upper pressure strip 641, all of the empty boxes stacked in multiple stages move downward together, so that the empty boxes in the lowermost layer are placed on the lower support hole 651 again. After that, the upper cylinder 64 is operated again so that the upper pressure strip 641 returns to its original state to hold the empty box located second from the bottom to wait for the next operation.

In this way, the stacking of the forklift (2) is carried out at the same time as the operation to receive a predetermined quantity and the space for receiving a new empty box while being stacked on the transport cart (7) at the same time, the new empty box falls At the moment, the discharge chute (S) retreats backwards and then moves forward again, a series of organic operations are performed in a set order, and such organic operations are carried out in a plurality of empty boxes (loaded into the empty box stacker 6). While the empty box loader 6 becomes empty when the transport cart 7 is lowered to the bottom by the stepwise descending operation of the forklift 2, which is repeatedly made until 8a) is completely exhausted. Since the plurality of seal boxes 8b in which the processed products P are quantitatively stored are stacked in the multi-stage in the transport cart 7, the worker loads the transport cart 7 on the forklift 2. It is a simple means of moving the workpiece, which transfers a large amount of the workpiece to a storage warehouse or a post processing line, thereby simplifying the transfer of the workpiece.

After transporting the transport trolley containing the workpieces by quantity as described above, the empty transport trolley 7 is placed on the forklift 2 again, and the forklift 2 is moved upward to the set position, and a plurality of empty boxes ( After inserting 8a) into the empty box stacker 6 and dropping the empty boxes one by one in the above-described manner, the process of storing the processed product P is repeated so that the box storage of the workpiece can be performed more efficiently. To improve productivity.

On the other hand, each of the upper pressure port 641 and the lower support port 651 attached to the piston of the upper and lower cylinders 64 and 65 of the empty box loader 6 are guide rods 643 attached to both sides thereof. Since 653 are assembled to the ball bush 642 and 652, the forward and backward operations are smoothly sliding, so that the operation of holding and releasing the empty box 8a can be expected to be accurate. The bin box stacker 6 is configured to adjust the installation height of the bin box stacker 6 using the adjustment holes 62 formed on the attachment members 61 on both sides thereof. It is possible to install the empty box loader at the height suitable for the working conditions such as the specifications and the specifications of the machine processing equipment for processing the workpiece.

Next will be described the operation state of the lifter device (1) for lowering step by step operation of the transport cart (7) loaded with the empty box (8a) receiving the workpiece (P) as described above.

The decelerated output of the deceleration sprocket 31 of the reduction gear 3 for decelerating the output to the brake motor 4 whose forward / reverse rotation and the number of rotational operations are controlled by the control device 5 is controlled by the chain 32. Since the drive shaft 13 is decelerated and rotated by being transmitted to the drive sprocket 14, the lifting chain 17 extended to the two interlocking sprockets 15 arranged on the drive shaft 13 is rotated in the forward and reverse directions. The forklift 2 is lifted and operated. In the state in which the forklift 2 is moved upward, the interlock sprocket 15 is rotated clockwise in the drawing. In this state, the lift chain 17 is also clocked. Direction, the lifting roller 21 of the forklift 2 is in a state of descending on the vertical stand 12 of the lifter device 1, and the forklift 2 is moved by a predetermined distance. Control device (5) when it reaches moving state Since the forklift 2 itself stops after only a predetermined distance and stops by controlling the brake motor 4, the carriage cart 7 descends step by step by repeatedly repeating the descending movement. Simultaneous empty box (8a) is to drop and stack one by one, so that the workpiece (P) is stored and stored by a predetermined amount. When the forklift 2 is completely lowered to the bottom, the transport cart 7 pulls the transport cart 7 by stacking the plurality of seal boxes 8b stacked in a state in which the processed products P are quantitatively contained. It is a simple operation to be transported to a desired location, that is, storage warehouse or post-process line, and then the operator places the empty transport cart 7 on the forklift 2 and moves the forklift 2 to a predetermined height. In this case, the storage work of the workpiece P is repeatedly performed.

According to the present invention as described above, the carrier is placed on the forklift of the lifter device and moved up and down to a predetermined height. Then, a plurality of bin boxes are put and stacked on the bin box stacker, and then the operation buttons of the control device are easily operated on. The operation allows the bin boxes to drop onto the trolley one by one to receive the workpieces, and to secure the space for the next bin box where the forklift descends by a certain distance in advance while the workpieces are contained in a fixed quantity.
