It is characterized in that a roller for guiding to the curved portion is provided.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. 1 and 2, 1 is a pair of right and left first guide rail, the first guide rail 2 to the side
Le 1 and provided in parallel, a second guide rail pair with the curved portion 2a. Sprockets 3 and 4 are provided at both upper and lower ends of the first guide rail 1, and a lifting chain 6 driven by a motor 5 is stretched between these sprockets 3 and 4.

Reference numeral 7 is a container holder. The container holder 7 includes a frame-shaped holding portion 7a for holding the container C conveyed by the conveyor 8 and an arm 7b on the side thereof.
This arm 7b consists of a horizontal arm and a horizontal arm as shown in FIG.
It has a T-shape with a vertical arm. And sideways
Rollers 10 at both ends of a first horizontal shaft 9 provided at the tip of the arm are fitted to the first guide rails 1 and 1, respectively. Also, as shown in FIG. 2, the first guide rail 1,
A second horizontal shaft 11 is provided between the two and is connected to a part of the lifting chain 6 so that it can be moved up and down. The upper ends of a pair of lifting rods 12 are pivotally attached to the second horizontal shaft 11, and rollers provided at both ends of the third horizontal shaft 13 at the lower ends of the lifting rods 12 are mounted.
14 is fitted in the second guide rail 2. Further, the lower ends of these lifting rods 12 are vertically aligned with the container holder 7.
It is pivotally attached to the lower end of the boom.

Therefore, when the elevating chain 6 is driven to elevate the elevating rod 12, the container holder 7 is pulled up through the elevating rod 12, but at this time, the tip of the lateral arm of the container holder 7 is pulled up. Part roller 10 is first
Of the container holder 7
The roller 14 at the lower end of the vertical arm moves up while being guided by the second guide rail 2. Moreover, since the second guide rail 2 is formed with the curved portion 2a as shown in the figure, when the roller 14 enters the curved portion 2a, the container holder 7 gradually begins to incline as shown in FIG.

An arcuate cam 15 is fixed to the first horizontal shaft 9 at the tip of the lateral arm of the container holder 7. This arcuate cam 15 is approximately as shown in the enlarged view of FIG.
A circular arc with a central angle of 120 degrees, with a collar 1 on its circumference.
It has 5a. This arcuate cam 15 is used for the container holder 7.
Tilts about the first horizontal axis 9, the angle changes accordingly.

On the other hand, on the first guide rail 1,
Near the center point of the curved portion 2a of the second guide rail 2,
The roller 16 is fixed. The roller 16 comes into the inside of the flange 15a of the arcuate cam 15 when the container holder 7 moves up, and its operation will be described in detail in the next section. Reference numeral 17 is a hopper, 18 is a chute fixed between the hopper 17 and the first guide rail 1, and 19 is an auxiliary hopper pivotally mounted on the container holder 7 about a shaft 20.

[0010]

Next, the operation of the container reversing device of the present invention will be described. First, in the state shown in FIGS. 1 and 2, the container C in which the products and the like are stored is conveyed by the conveyor 8 and enters the frame-shaped holding portion 7 a of the container holder 7. When the lifting chain 6 is driven upward from this state, the container holder 7 is pulled up via the lifting rod 12, but as described above, the roller 10 at the tip of the lateral arm of the container holder 7 has the first guide rail. 1 and also container holder 7
The roller 14 on the lower part of the vertical arm is the first guide rail.
It is guided by a second guide rail 2 provided parallel to the side of (1) .

However, when the container holder 7 moves up to the position shown in FIG. 3, the first end of the arm 7a of the container holder 7 is moved to the first position.
The arc-shaped cam 15 fixed to the horizontal shaft 9 of the roller hits the roller 16 fixed to the first guide rail 1. When the raising / lowering rod 12 further tries to pull up the container holder 7 from this state, the roller 16 enters the inside of the flange 15a of the arcuate cam 15. Therefore, even if the lifting chain 6 is driven upward from the state shown in FIG. 3, the roller 16 and the flange 15a of the arcuate cam 15 are engaged with each other, so that the first horizontal shaft 9 is further raised. Roller 14 as shown in FIG.
Since it enters the curved portion 2a of the second guide rail 2 and the container holder 7 rises while gradually inclining, only the container holder 7 rotates to reverse the container C, and the contents are hoppered.
17 Discharge up.

Thereafter, when the lifting chain 6 is driven to the lower side, the container holder 7 returns from the state of FIG. 4 to the state of FIG. 3, and the roller 16 may be pulled upward from the inside of the flange 15a of the arcuate cam 15. become able to. Therefore, by further driving the elevating chain 6 to the lower side, the container holder 7 can be returned to the state shown in FIGS.

[0013]

As described above, in the container reversing device of the present invention, the container C held by the container holder 7 is surely reversed at a predetermined position by simply moving the lifting chain 6 up and down, and then again. It can be returned to its original position. Moreover, the present invention does not require a complicated link mechanism for inverting the container C, which is advantageous in that there is no fear of failure and the manufacturing cost is low. Therefore, the present invention has an extremely great practical value as a container reversing device that solves the conventional problems.
