Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a bag reversing device.

(Prior art and its problems) For example, a bag filled with powder such as cement or granules such as wheat (hereinafter referred to as a filling bag) is widely handled in each industry.
These filling materials are automatically filled and sealed in the bag during the flow work process, and the quality, weight, etc. are stamped on the front and back of the bag.

It is often necessary to turn over during these operations, during storage in a warehouse, or for other processing operations. However, since the filling bag is heavy, it is difficult to automatically turn over many filling bags without affecting the filled material and without damaging the bag itself. Due to this reversing work, equipment having an expensive and complicated mechanism has been conventionally required.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a reversing device for a filling bag having a simple structure that can continuously and automatically turn over a heavy filling bag smoothly. is there.

(Means for Solving the Problems) In order to achieve the above object, the present invention relates to a cylindrical surface member 2 having an upward convex cylindrical surface and fixed by inclining the ridge line downward as it goes downstream. A first gutter-shaped member 3 arranged on the upstream side of the cylindrical surface member 2 for guiding and sliding the filling bag 1 on the cylindrical surface member 2, and on the substantially same plane from the first gutter-shaped member 3. And a first gutter extension 3'provided toward the downstream side and provided only on one of the left and right sides of the upstream ridge, and a vertical plane including the ridge, which is arranged below the cylindrical surface member 2. On the side opposite to the 1-gutter extension 3 ', there is an inclined surface inclined so as to approach the vertical surface as it goes downstream, and the filling bag falling while rotating from the cylindrical surface member 2 is further rotated on the inclined surface. A filling bag having a second gutter-shaped member 4 It is a reversing device.

(Embodiment) FIG. 1 shows a filling bag reversing device of the present invention. Cylindrical surface member 2
Is attached in a slanted shape in the drawing such that the front is low and the rear is high. A second gutter-shaped member 4 is mounted substantially parallel to the cylindrical surface member 2, and a gap is provided between the cylindrical surface member 2 and the second gutter-shaped member 4 so that the filling bag 1 can freely pass therethrough. The cylindrical surface member 2 is fixed to the second gutter-shaped member 4 by a support rod 6 so as not to move. The bottom of the second gutter-shaped member 4 has a width that allows the filling bag 1 to slide in the longitudinal direction.

A first gutter-shaped member 3 having a width capable of guiding and sliding the filling bag 1 is fixed to the top of the cylindrical surface member 2 by a welding portion 7 or the like. As shown in FIG. 1, the bottom portion of the first gutter-shaped member 3 is notched in parallel with the axis of the cylindrical surface member 2 to leave the first gutter extension portion 3 which is a part of the bottom portion, and An edge 5 is formed at the bottom in a direction crossing the gutter extension 3 '. The center of gravity of the filling bag 1 sliding on the first gutter-shaped member 3 is dimensioned so as to pass over the edge portion 5.

The operation of the device of the present invention having the above structure will be described. In FIG. 1, the filling bag (indicated by 1a) placed on the end portion of the first gutter-shaped member 3 slides on the first gutter-shaped member 3 in the direction of arrow A by its own weight, and the end edge portion 5 is pass.
After passing, one portion of the filling bag (the portion on the left side in FIG. 1) slides on the first gutter extension 3 ′ of the first gutter-shaped member 3 for a while, and the remaining portion of the filling bag 1 (FIG. 1). The part on the right side in) hangs by its own weight.

When the filling bag slides further, it is rotated by its own weight along the outer circumferential surface of the cylindrical surface member 2 in the direction of the arrow 13 and the inner surface of the second gutter-shaped member (Figs. 1 and 2), and is turned inside out. 2 Drop on the gutter-shaped member 4 (this state is shown by 1b). Further, it is slid in the direction indicated by the arrow by its own weight and discharged from the second gutter-shaped member 4 (this state is indicated by 1c).

In this way, the first gutter-shaped member and the second gutter-shaped member are provided above and below one cylindrical surface member, and the entire device is inclined forward, so that the filling bag can slide, invert, and slide by its own weight. You can go and smoothly flip the inside out.

(Effect of the Invention) Since the filling bag descends while being turned around around the cylindrical surface member by its own weight, the bag can be smoothly turned over without giving an impact to the bag itself. Also, the structure of the device is simple, and no special power is required for reversing.
