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, they used two tying machines to make a -shape tie with the whites of the eyes, and while moving to the second stop, they turned 90 degrees and tied it again in a 10-shape.

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 2 hours.

The present invention is mainly made of metal, and the inside of one of two arches (? arch(
? ) is fixed and erected on the center line of the main body parallel to the front, and the other outer arch ('') stands at right angles to the inner arch (?) on the left side edge.

The foot of the outer arch (?) moves parallel to the center so that it crosses the inner arch (?) in the middle, and the outer arch (?) is slightly separated from the main body (2) so that the legs of the outer arch (?) can move.

- The two sets of welding packing devices built into the blade body are arranged from the center of the front side and the center of the right side at right angles to the center of the main body, and the packing device from the right side is placed inside. It is for arch (?) and has two main bodies and a band reel αQ.
is installed, and secondly there is a band introducing drive roller (1υα) in the main body, and secondly there is a band box α0, and above it there is a drawer tightening drive roller α barrel a groan, and firstly there is a front with a window. There is a clamp pro, do(l!l), and there is a press rod 1201 as the primary.

Next, there is the rear cluster/plot circle, all of which are arranged in a line. 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 coarse motor (not shown). A band guide (1) is arranged so that the band αη from the right side that is fed out from the packaging device passes through the fixed inner arch (2), while the band from the front (22 is centered Insert the band guide (2) so that it passes through the moving outer arch (outer).
6a) is provided. Each band consists of an item to be packaged (30
The two arches (3) above the top plate (3) intersect crosswise at the center, and the band also intersects crosswise at the center. The band passage grooves 0104 that pass through also intersect in a cross at the center, and the passing band also intersects in a cross.The band αη from the right side is the band from the front side (from 23 to the object to be packed). The band passing mechanism is such that the band is wound at an inside position close to the
The template is attached to the board (marked 2) from both sides with hinges and springs, and is an L-shaped plate facing the item to be packaged.
Above the center of the upper part of the inner arch (2) is a protruding mechanism α→, and on the inside thereof there is a short and small band guide 4, and the short and small band guide (A) is connected to the band guide (trigger) inside the inner arch (2). ) is arranged as a short band guide with the width of the arch (2). There is a gap (41) by the width of the band (23) that falls on the center side of the inner arch (band guide (toward)) below it, and the outer arch (to which the blade moves) The band guide (26a) in ) is cut at the center to form a gap (41), and the upper center of the outer arch (≦) is a bridge 03 that protrudes upward to connect the left and right arches. Reinforced. When both arches (♀) (children) are combined in a cross shape in the middle, the center upper part of the inner arch (♀) and the extension mechanism area fit into the gap α◇ of the outer arch (≦).

The band is inserted between the cut band guides (26a) and (26a) so that the band passes through the cut guides (26a).

Band guide (2) installed inside the outer arch ('')
6a) and the short and small band guide ■ are opened on both sides and the band (
Flat sliding guides 4 are installed on both sides so that when the band guide (22) falls apart, it can pass through the gap between the band guide (1) of the lower inner arch (?).

On the other hand, the legs of the vertical arms of the outer arch (role) are slightly apart from the body (ri), and when the arch (3) moves to the center, the band f2'IJ is
A passage groove (to) and a band guide (26a) are arranged so as to pass through the band guide (26a) of the vertical arm of the outer arch ('') on the back side of the passage. Pass through the upper band guide (26a) in the arch (3), cross the short and small band guide [with] of the protruding mechanism ■, reach the arm on the front side, and cross the space 0'I) between the arm and the ceiling plate country. The band guide is arranged so as to pass through the band guide (26b) inside the lower body.

Also, the band passage groove (b) on the upper ceiling plate of the main body, the gap in the upper center between the band guide (to) and the inner arch (?) 0
1, the band guide (to) and the band guide on the side of the main body (on the other side) are made to pass through so that the band α can pass through.

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. The material to be packed is then flowed onto the front roller conveyor α and moved in the direction of the packing machine. When it enters the main body of the packing machine, it is carried to the center by the belt conveyor (7) of the main body.At this time, a sensor (not shown) senses it and the belt conveyor (7) stops.At the same time, the outer arch of movement (@) moves to the center by the action of the air cylinder (5), and the fixed inner part @p fits, and the outer arch (book)
The short and small band guide [with] inside the protruding mechanism (■) of the inner arch will be inserted in the middle of the band guide (26a).

This band guide (26&) and short and small band guide [available]
The band becomes a loop and the band (22 can go around inside the outside arch (''). Immediately, the switch is turned on and the band @ goes around the outside arch (9) and goes around the inside arch (22) which is going around first.
? ) will cross the band α force above and below the packaged object.

And the band α that goes around inside the inner arch (?) first
η goes around the inner side close to the item to be packed, and the lower part has a passage groove for the band α force (B) and another band (passing groove 0 for 221).
There is a step from 3 so that it does not get in the way. Also, regarding the upper intersection, one band passes through a low inner arch (?), and another band (2 passes through a high outer arch (?), so if it gets in the way, switch next. 9. Binding, welding, force, and tightening are completed in the same way as with conventional packaging machines. At this time, if the two sets of packaging devices built into the main body are turned on at the same time, the drawer drive roller α barrel Cυ
rotates in the opposite direction to tighten the band, but the band α force in the inner arch (?) is on the inside, and the band (22) in the outer arch (9) is on the outside, so the outer band @ is longer.

As a result, there is a time lag in tightening, and the inner band αη binds momentarily first.

Immediately after that, the outer bands (22) are bound together, and the bands no longer get in the way of each other, completing the cross binding and packaging.

Also, at the moment when the object to be packed 0→ enters under the inner arch (3) and stops, it is packed by the band α force of the inner arch (ri).

Next, as soon as the movement of the outer arch (trowel) stops, the outer arch (3) can be packed with two bands (2) to complete the cross-cross packing.

Immediately after cross-tied packing is completed, the outer arch (≦) moves to the left end, and the belt conveyor (7) works to unpack the packaged items (g).
is moved onto the rear roller bearing α force and transported to a predetermined position. The above operations are automatically repeated, and 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 (30b) to the intermediate gap 00 above the inner arch as shown in FIG. 14, the inner band αη can be easily passed through.

This passing band guide (30b) is designed so that when it is hit by the outer band (2z) falling from above, it rotates around the connecting pin (/43) and passes the outer band (22) through it. In other words, the inner band guide board (62a) and the board (32b) of the passing band guide (30b) are connected at the bottom by a bottle (c), and the outside Band guides (30a) and (30b) are respectively attached to the cover-like grooves so that both sides can be opened to allow the inner band αη to fall.

In addition, when using the present invention, the packaged items are suitable for bulk packing of newspapers, etc., as well as cardboard boxes, and in this case, there is a press that operates up and down with an air 7 cylinder on the upper right side of the fixed inner arch (?). Set up. This press is a combination of four presses, and the press surfaces are located above the inner and outer arches, and the four presses descend from the top of the arches, which intersect with each other, passing through each of the crosses of the arches. Newspapers are pressed and packed in cross-ties at the same time. Such a method is also possible.

The movement of the outer arch (≦) may be electrically driven. The positions of both arches do not have to be centered with respect to the main body. In addition, the opening of the next band guide of all the band guides arranged in succession is slightly widened into a pa-shape.

It is designed to easily accept bands. Further, the band guide may be a double-opening type or a single-opening type, or may be a device that allows the band to fall by shifting laterally in a U-shape and an open-shape. In addition, there is a method in which the outer arch is fixed and the inner arch is moved.The present invention allows for simultaneous cross-shaped binding, so if this is applied, it is possible to quickly pack items to be packed in a square shape or a square shape. become.
