Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing machine in which an object to be packed is swung on the packing machine for orthogonal banding.

[0002]

2. Description of the Related Art As a device for hanging a band on an object to be packed in a cross shape or a square shape, a device having a turntable installed between two packing machines or a device having a turntable separately provided in the packing machine (Fairy 4-39122), a device for suspending and rotating an object to be packed on a packing machine (Japanese Patent Publication No. 55-469).
28) is known.

[0003]

The above-mentioned hanging and swiveling method requires a strong lifting drive device in addition to breaking the band and damaging the object to be packed. According to the present invention, a pair of pressing pads for pressing both sides of an object to be packed are used to perform 90 ° rotation around the center of the object to be packed on a table of a packing machine for orthogonal banding and the tip of the pressing pad when banding. An object of the present invention is to provide a device which is designed to be opened so as not to interfere with banding, and which can be surely operated with a small amount of power and can be easily attached to an existing packing machine.

[0004]

SUMMARY OF THE INVENTION A packing machine according to the present invention includes a sealer unit on a lower surface of a table on which an object to be packed is placed and an inverted U-shape.
In a packing machine having a circular band arch, a swivel base having a swivel drive device is pivotally supported on the band arch via a swivel axis and is symmetrical on the swivel base with respect to the swivel axis. Is provided with a pair of slide members that are driven interlockingly with each other, and a sandwiching arm is vertically suspended and fixed to the pair of slide members symmetrically with the band arch interposed therebetween. A pressing pad having a pad and a driving device for the pad is fixedly configured. It is preferable to install the above-mentioned device in an existing packing machine, or to support the swivel base pivotally by fixing support frames on both sides of the band arch in order to enhance mechanical strength. An air cylinder is suitable for the turning drive device of the base, the drive device of the slide member, and the tip rotation pad drive device of the pressing pad.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 1 is a packing machine installed on a line for conveying articles to be packed, and 2 is a work table having a sealer unit and a band passage (not shown) on its lower surface. Reference numerals 2a and 2b denote rollers for loading and unloading the articles to be packed. Reference numeral 3 is a band arch, and 4 is an operation panel. Reference numeral 5 is a swivel holding device, which is provided on a band arch or on a support frame 6 which is erected and supported on both sides so as to be detachable so as to sandwich the arch as shown in FIG. Reference numeral 7 is a swivel shaft fixedly mounted on the support frame, 8 is a swivel base, 10 is a drive device such as an air cylinder, and the bottom side 10b is pivotally attached to the corner of the support frame and the rod end 10a.
Is connected to the side portion of the base by a pin to form a turning mechanism. Reference numerals 12a and 12b are slide guide rods arranged in parallel with the longitudinal direction of the base, and slidably support a pair of left and right slide members 14 and 15 in the middle. Reference numeral 16 denotes a slide member driving cylinder, which is supported by a bracket 17 fixedly mounted on a base, and the tip 16a of the rod is connected to one slide member 15. Reference numeral 18 is an endless chain for symmetrically interlocking both slide members 14 and 15, and is a sprocket 20, which is axially attached to both sides of the base.
It is stretched around 21 to connect slide members 14 and 15 to the forward and backward steps of the chain, respectively.
Protrusions 14a and 15a are symmetrically provided on the side edges of the slide member, and a clamping arm 3 made of a pipe material is provided on each protrusion.
0 and 31 are vertically symmetric with the band arch 3 interposed therebetween, and presser pads 33 and 34 are fixed to the lower ends of the holding arms so as to face each other. The structure of each pressing pad is the same, and as shown in FIG. 4, a pivot pad 41 hingedly connected to the tip of a pad body 40 pivotally fixed to the lower end of the arm is provided. Fixed cylinder 4
It is configured to open outward by about 100 ° or more by 2. The pad body 40 is provided so as not to be located in the band passage area on the table.

In the above apparatus, the swivel base 8 is shown in FIGS.
When the article P to be packed is fed onto the table in the standby state of No. 3, the pinching arm driving device 16 is actuated by the signal of the detection switch (not shown), and the holding pad 3 of the pinching arm is pressed.
3, 34 pinch both side surfaces of the article to be packaged to position the article to be packaged at the center (FIG. 4A). Next, the cylinder 42 operates to open the rotating pad 41, and the first band A is tightly packed (FIG. 4B). When the cylinder 42 operates in the opposite direction to close the rotating pad 41, the revolving cylinder 10 operates to revolve the revolving base 8 by 90 °, and the second band B is tightly packed at this position (Fig. Four
(C)). In this state, the revolving cylinder 10 is operated in the opposite direction to return the base 8 to the fixed position (FIG. 4 (d)), and then the holding arm drive cylinder 16 is operated and the pressing pad 33,
34 is made to retreat (FIG.4 (e)), and the to-be-packaged object P is released,
Transfer to the next conveyor. The packing mode and the carrying-in and carrying-out directions of the article P in the above steps are as shown in FIG.
Another packing method is as shown in FIG.
The operation up to pressing and holding (FIG. 6A) and packing of the first band A and the second band B (FIGS. 6B and 6C) is performed by the previous packing method (FIGS. 4A and 4B). , (C)), but
Immediately after the packing of the second band B is completed, the holding arm cylinder 16 operates to retract the pressing pads 33 and 34 to release the object to be packed, and then the swiveling cylinder 10 operates to return the pressing pad to the fixed position ( FIG. 6D). The packing mode and the carrying-in and carrying-out directions of the objects to be packed in this case are as shown in FIG.

[0007]

[Effect] The present invention only rotates 90 ° on the packing table of the object to be packed, and does not require the lifting mechanism. Further, since the swiveling and holding device is fixedly mounted on the band arch and can be mounted on a support frame which can be attached to and detached from a packaged item, it can be easily mounted on an existing packaging machine. In addition to being installed in the packing line, this packing machine can be operated independently and can be applied to small-scale applications. In this case, it goes without saying that the articles to be packed are carried in and out at the same location.

Next, the cylinder 42 operates to open the rotating pad 41, and the first band A is tightly packed (FIG. 5). When the cylinder 42 operates in the opposite direction to close the rotating pad 41, the rotating cylinder 10 operates to rotate the rotating base 8 by 90 °, and the rotating pad 41 holds the object to be packed in the second band. B is tightly packed (FIG. 6). When the packing and bundling work of the second band is completed, the swing cylinder 10 is operated in the opposite direction to return the base 8 to the fixed position (FIG. 7). At the same time, the holding arm drive cylinder 16 operates to retract the pressing pads 33 and 34 to release the article P to be packed (FIG. 8) and transfer it to the next conveyor. The packing mode and the carrying-in and carrying-out directions of the article P in the above steps are as shown in FIG. Other packing methods are as shown in FIGS. 10 to 13, and the operation up to the loading of the object P to be packed, the pressing and holding (FIG. 10) and the packing of the first band A and the second band B (FIGS. 11 and 12). Is the same as the previous packing method (FIGS. 4, 5, and 6), but immediately after the packing of the second band B is completed, the holding arm cylinder 16 is actuated to retract the presser pads 33, 34, and the backing pads 33, 34 are retracted. After releasing the packaged article, the swing cylinder 10 operates to return the presser pad to the home position (FIG. 13). The packing mode and the carrying-in and carrying-out directions of the objects to be packed in this case are as shown in FIG.
