目的とするものである。However, in the case of the conventional load lifting device described above, since the placing body is initially lowered to the low position, the rice bag sealing position on the placing body is also low, For this reason, the worker has to bend the waist to perform the sealing work as well, which causes a problem of fatigue of the waist and further deterioration of workability. Further, in the case of the conventional load lifting device described above, since the drive source using the motor, gears and the like is used, the lifting speed of the mounting body is not necessarily rapid,
There was a problem that the work efficiency was poor, the overall configuration was large, and the price was high. Therefore, the present invention has been developed in view of such a conventional situation, good workability without inducing fatigue of the waist of the worker, and quick lifting of a load and good work efficiency, Moreover, it is an object of the present invention to provide a load lifting device that can be downsized and reduced in cost.

A loader mounted in a state in which it can be rotated from the low position shown in FIG. 1 to the horizontal position shown in FIG. 5, a drive means 6 using a cylinder for driving the load carrier 5 from a low position to a horizontal position, and a power supply box 7 attached to the apparatus main body 2. As shown in FIG. 2, the load carrying body 5 is provided with a flat plate-like receiving plate 8, and the supporting shaft 4 is provided on the mounting end (one end) side of the receiving plate 8.
Is provided with a pair of attachment pieces 9a and 9b, and a pair of protrusion pieces (claws) 10a and 10b for placing a rice bag 20 or the like, which will be described later, on the protrusion end (the other end) side in a protruding arrangement. It is provided in. Further, at the end of the receiving plate 8 between the pair of protruding pieces 10a and 10b, the protruding piece 10
a, which uses, for example, a microswitch as a first detecting means for detecting the rice bag 20 or the like placed on a or 10b
The sensor 11 of is arranged. Further, a hole 8b is formed in the receiving plate 8, and a second detecting means, such as a microswitch, is used as a second detecting means for detecting that the rice bag 20 or the like is in contact with the receiving plate 8 in the hole 8b. Two sensors 12 are arranged. The driving means 6 comprises a cylinder (air cylinder or hydraulic cylinder) 13 whose bottom is rotatably supported by a fixing piece 2b provided on the apparatus main body 2, and a cylinder rod 13a of the cylinder 13 is attached to the receiving plate 8a. Is rotatably connected to the receiving piece 8a attached to the back side of the. Further, the driving means 6 is provided with a position regulating mechanism for regulating the lower limit position and the upper limit position of the load carrying body 5. That is, the position regulating mechanism is arranged along the cylinder 13 and is arranged on the cylinder rod 13
a slide body 14 having a contact piece 14a fixed to a;
A support arm 15 attached to the cylinder 13 to support the slide body 14 slidably along the cylinder 13, a lower limit switch 16 and an upper limit switch 17 fixed to the cylinder 13 at predetermined intervals. It is equipped with. The power supply box 7 is provided with an ON switch 21, an OFF switch 22, an ON lamp 23, an OFF lamp 24, etc. on its surface. FIG. 3 shows a control system of the load lifting device 1, which is provided with a control means (CPU) 30 for performing overall control, and this control means 30 includes the first and second sensors 11, 12, Lower limit switch 16, upper limit switch 17, on switch 21, off switch 22, on lamp 23,
The off lamps 24 are respectively connected. Also, the control means 3
0 is connected to a power supply circuit 31 and a timer 32 mounted in the power supply box 7. The power supply circuit 31 includes a commercial power supply (AC
100V or 200V) is supplied. Further, a cylinder controller 33 which constitutes the driving means 6 is connected to the control means 30. Next, the operation of the load lifting device 1 is mainly performed, for example, in the case where the rice bag 20 containing a predetermined amount of harvested fresh rice among the grains is sealed and lifted, and FIGS. Refer also to the explanation. Incidentally, in the initial state, the contact piece 14a of the slide body 14 comes into contact with the lower limit switch 16 of the position regulation mechanism, whereby the load carrying body 5 is moved to the position shown in FIG.
It is assumed to be stopped in the low position shown in. Under this condition, when the opened rice bag 20 containing a predetermined amount of the harvested fresh rice is placed vertically or substantially vertically on the protruding pieces 10a, 10b of the loader 5, the first sensor 1
1 is a control means 30 for detecting a signal indicating the presence of the rice bag 20.
Send to. As a result, the cylinder controller 33 operates under the control of the control means 30, and the cylinder 1
3 is driven to rotate the loading body 5 together with the rice bag 20 to the position shown in FIG. 5 to bring the lower end of the receiving plate 8 to a position of about 20 cm from the floor or the ground, and in this state, stop once. As a result, the rice bag 20 is lifted to a position higher than the original position and easy to seal. As a position where this sealing is easy,
For example, it is preferable that the upper end of the rice bag 20 is located at the waist of the worker and the subsequent sealing work can be performed without bending the waist. In this state, the worker wraps the upper end of the rice bag 20 without bending over and seals it, and further, as shown in FIG. 6, tie it with a tie string 20a to complete the sealing work. And the rice bag 20 after the sealing
Is brought into contact with the inclined surface of the receiving plate 8 of the load carrier 5, as shown in FIG. As a result, the second sensor 12 sends a detection signal indicating the presence of the rice bag 20 to the control means 30. As a result, the cylinder controller 33 operates again under the control of the control means 30, and the cylinder 13
To rapidly rotate the receiving plate 8 of the load carrier 5 together with the rice bag 20 to the horizontal position shown in FIG. In this state, the rice bag 20 after the sealing is also horizontally arranged and lifted to the easy transportation position. The easy-carrying position depends on the height of the operator, but is, for example, 70 degrees from the floor or the ground.
It is preferably about cm to 1 m. Further, when the receiving plate 8 is in the horizontal position shown in FIG. 8, the contact piece 14a of the slide body 14 comes into contact with the upper limit switch 17 of the position regulating mechanism, whereby the load carrying body 5 moves to the position shown in FIG. Stop at the horizontal position shown in. In this way, the rice bag 20 that has been lifted to the easy-to-transport position and has been subjected to the sealing is transported to another place (a warehouse, a truck bed, etc.) by an operator. Further, the horizontally-arranged loader 5 is provided with the rice bag 20.
After the timer 32, which operates with the off signal of the second sensor 12 due to the removal of the time, has finished counting the predetermined time, the cylinder 13 returns to the initial position shown in FIG. Become. As described in detail above, according to the load lifting device 1 according to the present embodiment, the rice bag 2 before being sealed
The sealing work for 0 or the like can be performed at the easy sealing position where the waist is not bent, the waist of the worker is not fatigued, and the workability is improved. Further, the rice bag 20 and the like can be quickly lifted from the low position to the easy sealing position and the rice bag 20 and the like can be quickly moved from the easy sealing position to the easy transportation position, and the work efficiency is good, and the cylinder Since the driving means 6 using 13 is adopted, downsizing,
It is also possible to reduce costs. The present invention is not limited to the above-described embodiments, but various modifications can be made within the scope of the gist thereof. For example, the present invention is applicable not only to the case described above, but also to sealing and lifting a storage bag for storing grains such as wheat and potatoes, vegetables, and the like, and is not limited to agricultural products, and various other products. It can also be applied to lifting.
Further, it goes without saying that the number of projecting pieces (claws) projectingly arranged on the projecting end side of the load carrying body 5 is not limited to that of the embodiment.
