Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is for automatically crisscrossing items to be packed using plastic bands.

Conventionally, after the --shaped binding, the items to be packed were rotated 90 degrees on the ceiling plate of the packing machine, and the single-shaped binding was performed again. Alternatively, two tying machines were used to make a 10-shaped knot at the - joint, and while moving to the second joint, the direction was turned 90 degrees and a --shaped knot was made again.

The present invention is characterized in that it is possible to perform criss-cross binding at the same time using two bands of one packing machine, thereby eliminating wasted time.

The present invention is mainly made of metal, and one inner arch of two arches (2) and (3) standing on the main body of a packaging machine that wraps, welds, and cuts the packaged items by making the band into an arc shape. (?
) is fixed and erected on the center line of the main body parallel to the front of the main body q), and the other outer arch (3) stands at right angles to the inner arch (?) at the left side edge.

The legs of the inner arch (≦) move parallel to the center and cross in the middle, and the legs of the outer arch (≦) move parallel to the main body (but are slightly separated from the outer arch (9).
Arms (4) are connected to both vertical arms of the machine so that they form an L-shape at right angles, parallel to the front of the main body, and the arms (4) have two protruding heads at both ends. .

This protruding head (B) fits into the slot (8) parallel to the arm (4) on both upper sides of the front and back sides of the main body (1).

It supports the outer arch (3) vertically, and the end of the protrusion at the end of the arm (4) is connected to the air cylinder (5) fixed to the main body, allowing the outer arch to move. The air cylinder is connected to a compressor (not shown).

On the other hand, the two sets of welding packaging devices built into the main body are arranged at right angles to the center of the main body from the center of the front side and the center of the right side, and the packing device from the right side is connected to the inside arch. (?) It is used for one body and a band reel α1.
is installed.Secondly, there is a band introduction drive roller (g) α0 inside the main body, and secondly there is a band pool box aQ, and above it there is a drawer tightening drive roller (11 (to)). There is a certain front tarpaulin rod α1, and the secondary press rod (to) is ant.

Next are the rear clan blond υ aashi, all arranged in a row. The front side for the outer arch (3) is arranged in the same way, but only the band reel (9) is installed side by side on the outside of the right side. Both drive rollers are connected to a drive motor, not shown. The band αη from the right side that is fed out from the packaging device has a fixed inner arch (a band guide (1) is arranged to pass through the inside of the box), while the band from the front (22 is centered Moving outer arch (band guide (26
a) is provided. Each band intersects in a cross shape at the center of two arches (?) (≦) above the object to be packed (G), and the bands also intersect in a cross pattern. The band passage groove (G) 3 that passes through the center of the ceiling plate (to) below also intersects in a cross at the center, and the passage band also intersects in a cross. The band αη from the right side is the band from the front side (221 has a band passage mechanism so that it is wound at an inner position closer to the object to be packed than the band 221, and all band guides are connected to a pair of L facing each other.
A template plate is attached to the board 4 from both sides by hinges and springs, and the L-shaped plate opens on both sides when facing the object to be packed (G) and returns to its original position. The fixed inner arch (2) has a band guide (1), and above the center of the upper part of the inner arch (2) there is a protruding mechanism, and inside it there is a short and small band guide (20). Band guide ■ is the band guide (to) inside the inner arch (♀)
A short band guide with the width of the arch is placed at right angles to the arch. The band that falls from the short and small band guide (with) on the center side of the inner arch (actual band guide (1)) below it (the gap O by the width of 22
The band guide (26 &) in the outer arch (2) where the blade moves is cut at the center to form a gap, and the upper center of the outer arch (3) is connected to the left and right sides. It is reinforced with a protruding bridge at the top that connects the arch. When both arches (2) and (3) are combined in a cross shape in the middle, the center upper protruding mechanism of the inner arch (2) fits into the gap αυ of the outer arch.

Both cut band guides (26a) (26a)
In the gap @η, there is a short and small band guide ■ installed on the inner arch (ri) upper protrusion mechanism 9, so that the band passes through it.

Band guide (2) installed inside the outer arch (3)
6a) and the short and small band guide ■ are double-opened and the band @
Flat plate sliding guides 4 are installed on both sides so that when the band is separated and falls, it can pass through the gap O0 of the lower inner arch (small band guide).

The legs of the vertical arm of the unilateral arch (≦) are slightly apart from the main body, and when the arch moves to the center, the band passes through the band of the ceiling board of the main body. #(3
3 and the band guide (26&) of the vertical arm of the outer arch (≦) on the back side, and the band @ is the outer arch (≦). Pass through the upper band guide (26a) inside, cross the short and small band guide ■ of the protruding mechanism ■, and reach the front arm. The band guide (toward) and the main body (the band guide at the end are band of) can pass through the gap 01 at the center of the upper part of the body.

Now, when the present invention is operated to achieve the purpose of automatically transporting a large amount of box-shaped items to a conveyor, packing them in cross-tie on the way, and transporting them again to the conveyor, the items to be packed are placed at regular intervals. At this time, the outer arch of movement (trowel) is placed at the left end of the main body (the trowel) so that it does not get in the way, so that the items to be packed are When the machine enters the main body, it is carried to the center by the main body's belt conveyor (7).At this time, a sensor (not shown) senses this and the belt conveyor (7) stops. In this case, the air nongoo (5) moves to the center and interlocks with the fixed inner arch (?) in a cross shape at the center.

The protruding mechanism ■ of the inner arch (?) and the gap 0υ of the outer arch ('') will fit together, and the protruding mechanism of the inner arch (?) will fit between the band guide (26a) of the outer arch (''). The short and small band guides inside will allow insects to enter.

This band guide (26a) and the short and small band guides 4 become threaded so that the band can go around inside the outer arch (≦). Immediately, the switch is turned on and the band (2) goes around the outside arch (≦) and intersects with the band α force in the inside arch (?) that has gone around earlier, above and below the object to be packed.

And the band α that goes around inside the inner arch (A) first
The force is circulated on the inside near the object to be packed, and there is a step between the band αη passage groove (B) and another band (2nd steepest passage groove (To)) at the bottom, so that it does not get in the way. Also, at the upper intersection, one band αη passes through a low inner arch (?), and the other band (2) passes through a high outer arch (ramie), so there is no interference. In other words, the band t23 goes around the outside far from the object to be packed.

Next, it is turned on and the machine finishes binding, welding, and cutting just like a conventional packaging machine. At this time, there is a built-in 2
If two packers are switched on at the same time, the drawer drive roller α07211 rotates in the opposite direction to tighten the bands, but the band αη in the inner arch (?) is on the inside, and the band (′) in the outer arch (9) is 23 is on the outside, so the outer band (the two are longer).Therefore, there is a time difference in tightening, and the inner band αη is tied momentarily first.

Immediately after that, the outer bands @ are bound, and the bands no longer get in the way of each other, completing the binding and packaging of the cross.

In addition, the moment the object to be packed /3Q'' enters and stops under the inner arch (?), it is packed using the band αη of the inner arch (?), and as soon as the movement of the outer arch (pregnant) stops, it is immediately placed outside. You can also wrap it with an arch (≦) band and complete the packing with a cross.

Immediately after the cross-tied packing is completed, the outer arch (?) moves to the left end and the belt conveyor (force is applied, and the packaged item 0Q is moved onto the rear roller bearing αρ and transported to a predetermined position. It is set to repeat automatically,
All of them are activated instantly by sensors, so they operate quickly one after another.

Furthermore, if the device starts the next operation while the previous operation is in progress, the time will be reduced accordingly.

Furthermore, by attaching a passing band guide (3Qb) to the intermediate gap (40) above the inner arch as shown in FIG. 14, the inner band αη can be easily passed through.

When this passing band guide (30b) is hit by the outer band (22) falling from above, it rotates around the connecting bin 03, passes the outer band (22), and springs again. It has a structure that allows it to return to its original position. That is, the inner buff guide board (62a) and the board (32b) (!) of the band guide (30b) are connected by pins (!) on the lower side, and the band guides (30a) and (30b) are connected to each other in the form of covers on the outside. The inner band αη can be opened on both sides so that the inner band αη can fall.

In addition, when using the present invention, the packaged items are suitable for bulk packaging such as cardboard boxes and other newspapers, and in this case, a press that is operated up and down by an air cylinder is installed on the upper right side of the fixed inner arch (?). Install. This press consists of four presses, and the pressing surfaces are located above the inner and outer arches, and the four presses from the top of the arches intersecting each other descend through each of the crosses of the arches to press the paper. At the same time as pressing, it is packed with cross ties. Such a method is also possible.

The movement of the outer arch ('') may be electrically operated. The positions of both arches do not have to be centered with respect to the main body. In addition, the mouth of the next band guide of all the band guides arranged in succession is slightly flared.

It is designed to easily accept bands. Further, the band guide may be of a double-opening type or a single-opening type, or may be of a U-shape and a device that allows the band to fall when it is shifted laterally from the U-shape. It is also possible to fix the outer arch and move the inner arch.

Since the present invention is capable of simultaneous criss-cross binding, if this is applied, it becomes possible to quickly pack items to be packed in cross-shaped binding and square-shaped binding.
