Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel container uncapping device that automatically removes container caps during transportation.

Conventionally, when storing edible oil, etc. in containers such as square iron, it is necessary to remove the cap, but this work is done manually, which not only requires a great deal of labor but also has poor work efficiency. There is a problem.

The present invention has been developed in view of these problems, and involves disposing a decapping member having a hook at the lower end while the container is being transported, and making this decapping member slide into contact with the top surface of the container being transported. However, the present invention provides a decapping device configured such that its hook portion is engaged with the cap of a container, and the cap is raised up as the container advances and is automatically removed.

Embodiments of the present invention will be described based on the drawings. In the figure, reference numeral 1 denotes a metal square-shaped container having a cinched peripheral edge 1a of an appropriate height on the periphery of the upper surface.
A cap 4 as shown in the figure is fitted. This cap 4 is required to have a flange 5 on its upper surface.

5 and 6 show an auto-out capper, that is, a decapping device for the cap 4 fitted to the container 1. Reference numerals 11 and 11 indicate a pair of side head; Back top. Container mounting conveyors 12 and 13 such as conveyors are arranged. The side belt 1
After the cap 4 of the container 1 is removed by a cap removal mechanism (described later) located above the cap 1 and 1, the container 1 is conveyed onto a carrier 12.

Reference numeral 15 designates a frame disposed above between the side belts 11, 11, and a horizontal guide 16 that hangs downward and whose rear end is deflected upward is provided at the rear of the frame, and a decapping member 17 is provided at the front. It's hanging down.

This cap removal member 17 is rotatably supported by a mini-bearing 18 provided on the frame 15, and is supported by a spring 19 at its cap hooking lower end 1.
7a is pulled so as to rotate rearward, and the stopper 20 prevents the rotation from rotating rearward beyond the hanging state.

Further, the decapping member 17 is formed into a U-shape using piano wire as shown in FIG. It is installed. Instead of this wire type, a thin iron plate 17c may be used as shown in FIG.
d is formed, and a resin is further applied to prevent the container 1 from being scratched. Further, the hook piece 17d may be made of resin.

Since the configuration is as described above, the operation state diagram shown in FIG. 9 will be explained.
The container 1 gripped by the caps 1 and 11 is conveyed forward (see figure a), and the container 1 is conveyed to the front by the decapping member 17 at the rear.
crosses over the front edge 6 of the container 1 and places the rings or rollers 1 on both ends of the lower horizontal hook on the upper surface 2 of the container 1.
While sliding contact with cap 7b, approach cap 4 (same b
When the cap 4 is reached, the lower end 17a of the cap removal member 17 hooks and raises the collar 5 of the cap 4 as the container 1 advances (see figure c), and the raised cap 4 is It is turned over and falls downward (see figure d). The front decapping member 17 is for things that cannot be removed by the rear member 17, and is intended to improve the probability of decapping.For example, as shown in FIGS. 7 and 8, there are It is desirable to install something.

By the above operation, the cap 4 made of synthetic resin for preventing the inclusion of foreign matter can be removed and simultaneously collected from the container 1 having the cap 4 without causing any damage to the container 1 or the opening 3, unmanned and automatically.

Although the material of the cap 4 is not limited, it is limited to a cap with a flange so that it can be pulled up and removed. Although the material and shape of the container 1 are not critical, it is necessary that the opening 3 be located upward, and that the container 1 can be transported using a top chain and side belts.

The above-mentioned decap member 17 and both side belts 1
1 and 11 can be adjusted to match the shape of the container 1.

Further, although the decapping member 17 is installed in two places, it may be installed in one place, and when it is installed in two places, its shape is changed.

Furthermore, by making the speed of both side belts 11, 11 slightly faster than that of the top conveyors 12, 13, the space between the array containers 1, 1 becomes wider, so that the fall of the caps 4 is constant, and the caps can be collected below. It becomes easier.

As described above, according to the decapping device of the present invention, it is possible to automatically remove the caps of containers held and conveyed by a pair of side belts one after another at the cap hooking lower end of the decapping member, and furthermore, this decapping device It is possible to smoothly and reliably lock the member to the cap by using the advancing force of the container while slidingly contacting the upper surface of the container, and then immediately remove the cap. Therefore, this work can be done efficiently. At the same time, it is possible to continuously automate the next process such as the content storage process.
