The object of this invention is to eliminate the drawbacks of the prior art as described above, and to provide a boxing machine that can box heavy items or weak containers filled inside without causing any damage. purpose.

This invention will be explained below based on the drawings.

Figure 1 shows a plan view of the packaging machine based on this invention, and Figure 2 shows a plan view of the packaging machine based on this invention.
Each figure shows a side view, and a boxing machine 2 according to this invention is disposed continuously at the leading end side of a conveyor 1 for conveying the filling. A rotary frame 5 whose one side is pivotally supported by 4 and whose interior is hollowed out in a rectangular shape is swingably provided, and the rectangular space 6 near the other side of the rotary frame 5
Inside, one side portion of a sliding frame 7 is provided so as to be swingable by a driven shaft 8.

Further, two main body guides 9 are provided on both sides of the rotating frame 5 in parallel with each other in the same direction as the traveling direction of the filling conveyor 1, and the tip of the main body guide 9 on the other side of the rotating frame 5 is curved toward the main body guide 9 on one side.

are connected with.

The sprocket I.10 on the rotating shaft side is fixed to the machine frame 3 and is rotatable with respect to the rotating shaft 4, and the sprocket 11 on the driven shaft side is fixed to the driven shaft 8.

A first air cylinder CYL-1 is provided at one end of the rotating shaft 4 via an arm 13, and near the rotating frame 5 on the opposite side to the first air cylinder CYL-1, the filling conveyor 1 is installed. A person-lost collar 14 that projects so as to cross the conveyance surface at right angles in the horizontal direction and a second air cylinder CYL-2 that operates the collar are provided.

A cushion conveyor 16 having a conveyance surface substantially perpendicular to the conveyance surface of the empty box conveyor 15 is provided adjacent to the conveyor 15 for conveying empty boxes, which is provided near one side of the rotating frame 5 and slightly below. A discharge conveyor 17 is provided on the tip side.

In addition, 21 is a side guide, LS is a one-way switch provided on the machine frame 3 and whose operating part protrudes from the rotating frame 5, and LS2 detects when the rotating frame 5 is tilted at a predetermined angle and issues a signal. limit switch, L

A non-contact switch detects when it is transported and issues a signal, S■1 is a solenoid valve that operates the first air cylinder CYL-1, and S■2 is a solenoid that operates the second air cylinder CYL2. The valve CYL-3 is a third air cylinder whose actuating part can protrude horizontally at right angles above the empty box conveyor 15, and CYL-4 is the third air cylinder that can project above the empty box conveyor 15 at right angles.

Reference numeral 5 designates a box raising air cylinder whose operating portion is capable of protruding at right angles in the -L direction from below the conveyance surface of the conveyor 15, and Sv3 represents the third air cylinder CY.
L3 is a solenoid valve that operates the fourth air cylinder CYL-4 and the box-raising air cylinder CYL-5.

Next, the operation of the above-mentioned device will be explained with reference to the circuit diagram shown in FIG.

When the rotating frame 5 is positioned horizontally and the conveyor 1 conveys the cylindrical filling el19, this filling @
19 is guided by both main body guides 9 and sequentially rotates the frame 5.
It is conveyed onto a sliding plate 7 located in a rectangular space 6.

When the filling material 19 at the tip being conveyed activates the limit switch LS, this causes the sliding plate 7,
, , , , lr, it is confirmed that two fillings are aligned.

In addition, since the rotating frame 5 is also in a horizontal state, the limit switch LS3 is also activated, which causes the relay
When solenoid valve SV2 is activated, the second air cylinder CYL-2 is activated to project the inlet stopper 14 onto the conveyor 1 and stop conveyance of the next filling.

Then, when the empty box 18 is conveyed by the empty box conveyor 15, it is confirmed by the non-contact switch PH.

In this case, since the fourth air cylinder CYL-4 is activated and protrudes above the empty box transport conveyor 15, the empty box 1
8 at a predetermined position.

Then, the solenoid valve SV1 starts operating by this contactless switch PH and the relay X1, and the first air cylinder CYL-1 pulls the arm 13 clockwise in FIG. Rotate clockwise.

At this time, the sliding plate 7 also tilts downward at the same time, but the sprocket 10 for the rotating shaft and the sprocket 11 for the driven shaft are connected by a chino 12, and the sprocket 10 for the rotating shaft
is fixed to the machine frame 3, so it rotates counterclockwise relative to the rotating shaft 4, the driven wheel sprocket 11 also rotates counterclockwise, and the sliding plate 7 rotates counterclockwise relative to the rotating shaft 4. It will be rotated counterclockwise around the center.

For example, if the ratio of the number of teeth between the rotating shaft sprocket 10 and the driven shaft sprocket 11 is 3:2,
If the rotating frame 5 is tilted 60° clockwise, the sliding plate 7 will be tilted 90° counterclockwise with respect to the rotating frame 5, and the filling 19 on the sliding plate 7 will be tilted at 30° with respect to the horizontal plane. You will be skiing down the slope at a slope of .

Then, the inclination angle of the empty box conveyor 15 is set to 30', so that when the empty box to be conveyed is tilted, the lower side surface becomes the same plane as the upper surface of the sliding plate 7.
9 slides down into the empty box 18.

When the rotating frame 5 has finished tilting downward, when the limit switch LS2 is activated, the timer TM is activated and the relay X1 is deactivated after a predetermined period of time, for example, 0.5 seconds. The first air cylinder CYL-1 is returned to its original state, and thereby the rotating frame 5 is rotated counterclockwise via the arm 13 to a horizontal state.

When the rotating frame 5 becomes horizontal in this way, the limit switch LS3 is activated and the solenoid valve SV2 is activated.
and ``Input via the second air cylinder CYL-2.''
The stopper 14 is retracted to feed the next filling 19 into the sliding plate 7-hi.

Further, at the same time as the timer TM is activated, the relay −
4 is retracted to carry out the box 20 filled with the filling.

When this box 20 is confirmed by the limit switch LS4, the operation of the limit switch LS4 causes the third air cylinder C to
Retract YL-3 to bring in the next empty box, and move the fourth
The air cylinder CYL-4 is projected to stop the empty box 18 at a predetermined position.

At the same time, the box edging air cylinder CYL-5 is also operated, whereby the box 20 is raised to its normal position and transported to the next process.

Thereafter, by repeating the above-mentioned operations, the fillings are sequentially packed into boxes, and these boxes are transported to the next process.

In addition, in the above embodiment, the sprocket provided on the rotating shaft and the sprocket provided on the driven shaft were connected via a chino, and the rotation was transmitted by the first air cylinder, but the invention is not limited to this. It goes without saying that the same effect can be obtained even if the rotary shaft and the driven shaft are rotated by providing separate air cylinders for each. has the same effect.

With this device configured as described above, the filling material is tilted by the frame member and the support plate member and is allowed to slide down into the empty box. Compared to this, the sliding speed is slower and the impact of the container during packaging can be reduced, preventing damage to the filling, and one side of the frame member can swing against the machine frame by the first rotating shaft. The support plate member is attached to the other side of the frame member so as to be swingable by the second rotation axis, and the frame member is tilted downward about the first rotation axis. Since the support plate member is tilted downward about the second rotation axis, the filling material is transferred downward without being lifted up against the gravity of the filling material. It has the excellent effect of being able to pack even heavy materials such as earthen tanks into boxes with a small amount of power, and because of its extremely simple structure, it can be manufactured at low cost and prevents breakdowns. It also has excellent effects, such as having a small footprint and requiring only a small installation space.
