Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic opening/closing method for opening and closing containers containing various fluids such as powder or liquid foods with their openings slanted downward and opening/closing the lids to discharge the fluids. It is related to the device.

In this type of container, the container body is arranged so that its opening is slanted downward, and the lid that closes this opening is pivoted on the edge of the opening of the container body and provided on the inner surface of the lid so that it can be opened by its own weight. Some containers are designed to close a lid by rotating a cam by rotation of a rotating shaft that engages the cam and engaging a latch piece on the container body. In the conventional technology, when opening and closing the rose, a manual rotating shaft was inserted into the cam of the lid and the cam was rotated by hand, which required a large amount of force from the operator and the lid was difficult to reach from the ground. The purpose of the present invention is to eliminate the need for one worker's effort and to allow the worker to stand on a high platform to open and close the work. To provide an automatic container lid opening/closing device capable of safely opening and closing a container without any trouble.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an automatic container lid opening/closing device 10 according to the present invention,
The container 12 has a container body 14 arranged on the upper frame 1 so that the opening 14a is slanted in the r direction, and a pin 16 attached to the edge of the opening 14a of the container body 12 so that the opening 14a opens under its own weight. It consists of a lid 18 which is pivoted at. The opening 14a of the container body 14 disposed on the upper frame 1 is in close contact with a conduit 3 extending from a receiver (not shown) mounted on the lower frame 2, so that the fluid inside the container 12 can enter the receiver via the conduit 3. It is about to be introduced.

? 518 has a cam 20 provided on its inner surface,
This cam 20 is rotatably supported by a bush 22, and its periphery is rotated by the rotation of the cam 20.
The lid 18 is opened and closed by engaging with and disengaging from the lid 4. The cam 20 passes through the bushing 22 and closes the lid 18.
It has a protruding shaft 21 that protrudes to the outside, and this protruding shaft 21 is provided with a cross-shaped engagement portion 21a (see FIGS. 2 and 3).

The automatic lid opening/closing device IO of the present invention, as shown in FIG.
A rotating shaft 28 having a head 26 that engages with the cross-shaped retaining portion 21a of the protruding shaft 21 of the cam 20, a motor 30 for rotating this rotating shaft 28, a rotational drive source 34 including a chain sprocket mechanism 32, and the rotating shaft 28. The rotation drive l! 34, and linear drive source 36 such as an air cylinder that linearly moves forward and backward with respect to the protruding shaft 21- of the cam 20.

As shown in FIG. 4, the linear drive source 36 is connected to a pair of pivots on a mounting frame 42 of a swinging mechanism 43, which is comprised of a mounting frame 42 swingably mounted on a bracket 38 mounted on the lower frame 2 with a central pin 40. It is pivotably supported by a support pin of 44.44 degrees. The inclination adjustment mechanism 46 engages both sides of a protrusion 48 protruding from the lower surface of the linear drive source 36 and is attached to the mounting frame 42 (bracket) 5.
A pair of adjustment screws 52.5 screwed together through 0.50'
2° and therefore these adjusting screws 52 , 52
The inclination of the linear drive source 36 can be adjusted around the pivot pins 44 and 44' by moving them forward and backward in opposite directions.

In addition, on the IJ plane, the reference numeral 54 is attached to the bracket 38 (
It is arranged between the mounting frame 42 and the mounting frame 42 to prevent the mounting frame 42 from slipping (
56.56' indicates the bracket 50.56 to prevent the adjusting screws 52, 52° from loosening.
50' and adjustment screws 52.52' spade 52a, 52
' shows the spring installed between a and a. Furthermore, code 5
Reference numeral 8 denotes a rotating shaft 2 in order to prevent the liquid discharged from the opening 14a from being contaminated by this device when the lid 18 is opened.
8, and reference numeral 60 indicates a backing that maintains fluid tightness between i18 and opening 14a.

As shown in FIG. 1, the sprocket 32A to be connected to the rotating shaft of the chain sprocket mechanism 32 is connected to the rotating shaft so that the rotational drive #i34 is connected to the rotating shaft 28 regardless of whether the rotating shaft 28 advances or retreats. 28 with a spline connection.

In addition, in order to regulate the forward and backward movement of the rotary shaft 28, limit switches 62, 62 are provided on the piston 36a of the cylinder, which is the linear drive source 36, to regulate the forward position and the backward position.
A sprocket 32A connected to the rotating shaft 28 is provided to control the rotation angle of the cam 20 so that the lid 18 is locked or released as shown in FIG. Also provided is an operating member 68 that contacts a limit switch 66.66° that regulates the locked position and the unlocked position.

Next, 1. After the operation of the device of the present invention, 2. Normally, the Schilling piston, which is the linear drive source 36 of the rotating shaft 28, is the first
As shown by the dotted line in the figure, when the linear drive source 36 is driven and the rotary shaft 28 is advanced in order to open [18] of the six containers 12 which have been retracted until the limit switch 62' is closed, the rotation shaft 28 is moved forward. As shown in the figure, the head 26 has nine rotating shafts 28.
engages with the cross-shaped protruding shaft 21 of the cam 20. In this case, the head 26 and the cross-shaped protrusion @121 are secured by swinging the linear drive source 36 around the center pin 40 of the swing mechanism 43, and by using the adjustment screws 52, 52' of the tilt adjustment mechanism 46. This can be done reliably by adjusting the position of the head 26 by adjusting the screws in mutually opposite directions. Next, the one-turn drive source 34 is driven until the limit switch 66'' is closed, and the rotating shaft 28 is rotated until the cam 20 is in the unlocked position, and the cam 20 is released from the latching piece 24 of the container body.After that.

When the linear drive [t36 is driven in the opposite direction until the limit switch RO 2° is closed, the lid 18 will move back due to its own weight as the rotating shaft 28 retreats, so the lid 18 will open and the fluid in the container body 14 will flow into the conduit 3. It is then discharged. After all the fluid has been discharged, the linear drive source 36 is driven in the forward direction.
Next, the rotary drive unit 34 is driven in the locking direction to lock the cam 20 to the latch piece 24, and finally the linear drive source 3
6 in the backward direction to remove the device from the lid 18.

According to the present invention, as described above, since the lid of the container can be automatically opened and closed, there is a practical benefit that work can be performed safely and efficiently.
