BACKGROUND OF THE INVENTION
The present invention relates to an ascending / reversing and feeding apparatus for a container for raising a cylindrical container such as a drum can and applying a reversing operation so as to put a substance in the container into a hopper provided at a predetermined height.
[0002]
[Prior art]
Conventionally, as this type of apparatus, a cylindrical container such as a drum can is lifted up to a predetermined height and then automatically falls by a link mechanism.
Further, for example, Japanese Utility Model Publication No. 57-23438 discloses a container lifting and tipping device. FIG. 11 shows a front view of the apparatus. This is provided with a main pillar 51 in the vertical direction and a guide pillar 52 parallel thereto, and a semicircular guide portion 53 is formed at the upper end of the guide pillar 52 so as to cover the upper part of the main pillar 51 continuously. In addition, the elevating frame 54 is provided on the main column 51 so as to be able to travel freely, and the tipping frame 58 having a roller 59 that runs on the guide column 52 is provided on the guide column 52, and the container holder 64 is connected to the tipping frame. Further, the guide column 52 is provided with a swing link 56 having a roller 57 in the middle for running on the guide column 52. The tip of the swing link 56 is provided at the rear end of the fall frame 58 and the swing link. 56 is a container lifting and falling device in which the rear end of 56 is rotatably connected to the lifting frame 54.
[0003]
When the drive chain 62 is driven in the direction of arrow A62 in the state shown in FIG. 11, the elevating frame 54 rises along the main column 51 via the coupling fitting 63, and the rollers 59 of the swing link 56 and the fall frame 58 are guided. When reaching the semicircular guide 53 at the upper end of the column 52, the fall frame 58 starts to rotate counterclockwise about the pin 61. At this time, the container holder 64 and the drum can 69 fixed to the fall frame 58 also rotate together and start to fall smoothly. When the elevating frame 54 is further raised and the roller 57 of the swing link 56 reaches the semicircular shape 53, the swing link 56 also starts to swing counterclockwise about the pin 60. Finally, stop in the state indicated by the chain line in the figure. That is, the drum can 69 is turned over and turned upside down like 69a.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional one, when the cylindrical container is raised to a predetermined height and then the reverse charging operation is performed along the semicircular guide portion 53, the increasing speed of the center of gravity height of the container is increased. Since the rollers 59 and 57 increase 3.5 times or more compared to when the rollers 59 and 57 are moving along the straight portion of the guide column 52, the required power is increased. Moreover, the throwing-in operation was performed abruptly, and there was a case where it was inconvenient because the splashes were scattered.

The part 10b is fixed as an end point. A tension wheel 28 is provided so that slip between the planetary gear 7 and the rotation chain 10 does not occur.
[0009]
Reference numeral 9 denotes a holder that can hold the drum-like container 8 in an inverted manner, and is fixed integrally with the planetary gear shaft 7a. The holder 9 is formed in a frame shape, and a bolt-shaped presser fitting 9a is detachably provided on the upper portion. Further, the semicircular upper edge portion 9b of the holder 9 is supported by the support shaft 9c as an opening / closing frame so that the container 8 can be taken in and out while sliding from the front, and is provided to be rotatable in the front-rear direction. ing. Reference numeral 29 denotes a table roller which is arranged so that the container can be smoothly inserted and removed from the front, and is installed with a space open so as not to hinder the vertical passage of the holder 9.
[0010]
FIG. 4 illustrates an operation in which the container 8 according to the first embodiment is given a reversing and charging operation. The sun wheel 3 that has risen to the position of the solid line continues to rise together with the lifting frame main body 2, but the guide roller 5 is lifted obliquely upward by about 45 degrees. For this reason, the bell crank 4 rises while rotating clockwise 4A2, 4A3, 4A4 sequentially from the state of 4A1. At the same time, the planetary gear 7 sequentially rises to 7A2, 7A3, and 7A4 from the state of 7A1, and rotates counterclockwise according to the planetary movement principle of the planetary gear. At the same time, the container 8 held by the holder 9 integrated with the planetary gear 7 is sequentially rotated to 8A2, 8A3, 8A4 from the state of 8A1. This is similar to the operation of holding and lifting the liquid container with both hands and slowly and slowly putting the contents. For this reason, the drum can container can be smoothly raised and reversed.
These operations are calculated numerically as follows.
If the diameter ratio between the sun wheel 3 and the planetary gear 7 is 2.5: 1, the angle at which the bell crank 4 holding the planetary gear 7 changes from 4A1 to 4A4 is θ (90 degrees), and the planetary gear 7 is integrated. When the angle at which the container 8 changes from 8A1 to 8A4 is α, α = 2.5θ−θ = 135 degrees.
[0011]
Next, the overall operation will be described. First, the drum can 8 containing the contents is inserted into the holder 9 in a vertical state from the front using a forklift, and the semicircular upper edge 9b is closed to prevent lateral movement and a bolt-shaped presser. The metal fitting 9a is tightened to prevent the movement in the vertical direction. Next, when the motor 22 is started, the rotation is decelerated and the rotation is transmitted to the sprocket wheel 26 to raise the elevating chain 21, and the elevating frame body 2 connected thereto rolls the elevating guide rail 1. The two rollers 2a are moved up vertically to a certain height. Thereafter, as shown in FIG. 4, the bell crank 4 is raised clockwise together with the elevating frame body 2 and is rotated clockwise, and at the same time, the planetary gear 7 is rotated counterclockwise together with the holder 9. Is given to the container 8 and the reverse charging operation is given. In order to finish the closing operation and return it to the original state, the sprocket wheel 26 is rotated in the reverse direction and returned through the reverse operation.
[0012]
In the first embodiment shown in FIG. 1 to FIG. 4, the reversal charging operation is performed in the rotation axis direction with respect to the container receiving direction, that is, the rotation direction of the table roller 29, and the changing angle α is set to 135 degrees. However, as a second embodiment, as shown in FIGS. 5 to 7, a reverse feeding operation is performed in the back direction with respect to the container receiving direction, that is, the rotation direction of the table roller 29, and the changing angle α is set to 180 degrees. You can also [0013]
The main difference of the second embodiment from the first embodiment is that the container receiving direction, that is, the arrangement direction of the table rollers 29 is different by 90 degrees in the second embodiment and the first embodiment. In the first embodiment, the support of the container and the reverse loading operation of the container are performed by cantilever support, whereas in the second embodiment, the support of the container and the reverse rotation operation of the container are supported on both sides. This is advantageous because it makes the strength stable.
[0014]
FIG. 7 corresponds to FIG. 4. In FIG. 4, the diameter ratio between the sun wheel 3 and the planetary gear 7 is 2.5: 1. In FIG. 7, the diameter ratio between the sun wheel 3 and the planetary gear 7 is 3: By setting it to 1,
α = 3θ−θ = 180 degrees, so that the reverse inversion operation of 180 degrees can be performed.
[0015]
In the above embodiment, the rotating chain 10 is not an endless chain but has terminal portions 10a and 10b. However, it may be an endless chain. Further, the turning chain 10 may be a string or a belt as long as it can prevent slipping.
[0016]

At the same time, the planetary gear 7 is rotated together with the holder 9 so that the container 8 protrudes and reversely throws in, so that the bag holds the liquid container with both hands. As it can be lifted up and charged slowly and gently, it can be lifted up smoothly and reversed, so there is no risk of splashing and it can be reached even if it is not close to the container to be charged. Thus, workability is improved.
In addition, since the change in the increasing speed of the height of the center of gravity of the container in the ascending and reversing operation is small, the power consumption is small and the power cost can be saved.
