v11 Claims.

This invention relates to packaging apparatus and more specifically to apparatus for packaging bags which have tags attached.

In general, it is an object of the invention to provide a device of the character described which will efficiently perform the purposes for which it is intended, which is simple and economical of construction, which can be expeditiously, conveniently and safely manipulated, and which can be readily manufactured and assembled.

Another object of the invention is to provide a device which wraps a plurality of bags and tags, each bag with its own tag being enclosed in an outer wrapping, i. e., which prevents a tag which is connected to one bag from being wrapped with another bag; to provide such a device which utilizes the force of gravity to assist in accomplishing the particular result desired.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts, which willbe exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of theinvention, reference should be had to the following detailed description, taken in connection with the accompanying drawings, in

- which:

Figure 1 is a perspective view of a device embodying one form of the invention;

Fig. 2 is a cross-sectional view, in elevation, of a portion of the device shown in Fig. 1;

Fig. 3 is a view of the bag and tag separating elements; and

Fig. 4 is a view of the bag propelling element.

Certain materials such as tea, etc., are often enclosed in small cloth bags with a tag connected by a string or the like to the bag. The tag may have information printed on it regarding the maker, the grade of material, etc. It is sometimes desired, for various reasons, to enclose the bag and tag in a protective wrapping which may be of coated Cellophane or other like sheet material. One general method of wrapping is to introduce, one after another, the bags with their respective connected tags between strips of Cellophane and to seal off the Cellophane around each successive bag with its tag. It has been found that frequently the tag connected to one bag would become positioned near the preceding or succeeding bag with the result that the wrong tag has been sealed in a bag. The shearing means which separate the successive wrapped bags has cut the string leading from the tag in one package to its proper bag in the next package. When the customer opened the packages,

a loose tag would fall out or there might be no tag at all. The present invention contemplates a device for overcoming this and other difliculties heretofore known.

In the drawings, l8 denotes generally means for successively supplying objects such as bags, etc., which are connected to tags. i 2 denotes generally mechanism for spacing each tag from its bag. It indicates mechanism for bringing each bag and tag together again and I6 indicates generally the means for successively wrapping together each bag with its own tag.

The bag-supplying means may be of any convenient form, that shown being an endless conveyor l8 having hoppers 20 attached thereto which each dump a bag and tag into hopper 22.

dimensions that they prevent the passage of a bag but do not prevent the dropping throughthe grille of the tag. Gravity normally pulls the tag through thegrille and thus spaces the bag and 1 tag.

The grille means may take various forms, that shown being a pair of multiple tined forks 24. Each comprises a rotatable rod 26 to which the spaced tines 28 are attached. The rods are horizontally parallel and the tinesextend toward each other, preferably downward. The material may be intercalated, if desired. Means described below are provided for rotating the rods and spacing the ends of the tinesso that a bag may fall therethrough and down through the bottom of the hoppers to be caught between the vertical, spaced, parallel portions of endless belts 30. The distance between these portions is such that a bag does not fall through between those portions but is carried along downward by, and in contact with, them.

As the bag passes downward, it is preceded by its depending tag. A propelling finger 32 is positioned toward the end of the travel of the bag between the belts 30. Mechanical means described below are timed to cause the finger 32 to enter the space between the belts and knock the bag, which is present at that time, downward with increased velocity so that it overtakes its own tag and falls, with it, between the wrapping wheels 34.

The wheels 34 each have two end rims 36 which are separatedirom the two similar rims of the other wheel only by the thickness of two 20 Grille means are provided in the hopper of such These webs. are brought from suitable sources 'oi'supply such as the spools 40 and pass'over and down between the wheels 34. The rims 34, which may be knurled or corrugated, press the edges of oneweb against the edges of the other separate one cavity from the next. The wheels are adjusted so that as they revolve, the surface portions 42 ofone wheelmeet the surface portions 42 of the other wheel. Thus, with the turning of the wheels, successive chambers are presented into which successive bags drop. The bags do not touch the wheels because the webs arepassing over the wheels. The bags are ,accordingly caught between the webs, the longitudinal edges of which are being sealed by the action of the wheelrims. The whee. chambers permit each bag to pass'down between the wheels. Beneath the bag, as it passes down, the webs have been sealed by the pressure of the surfaces 42. As each bag leaves the wheels, the webs are sealed behind the bag and its tag by the next contacting surface 42. Shearing means 44 cut the webs between successive bags which are than free to drop onto a finally disposingconvey'or 46.

The sealing of the webs may be facilitated by heat which can be supplied to the wheels 34. The belts 30 may be driven from a source (not. shown) by the rotation of pulleys H over which the belts pass. I

Any suitable means may be used for coordinat ing and synchronizing the motion of conveyor III, the opening of the forks 24, the motion of the propelling finger 32, the rotation of the wheels 34, and the shearing action of 'the means 44. Thus, a cam H2 on a mutual shaft H4 with pulley H0 may actuate a roller H6 tooperate linkages H8 and H9 which cause the periodic and sudden motion of rotation of the rods 26.

As shown, linkage H9 is pivoted on pivot I attached to hopper 22. One of the rods. 26 is attached to linkage H9. The other rod 26 is attached to a link I2I pivoted about pivot I23 on the hopper. Cam surfaces I25 on linkages H9 and links I23 cause the latter to rotate when the former rotate. This rotation of the bars and their tines about pivots I20 and I23 causes the distal ends of the tines in one set to separate from the distal ends of the tines in the other set. A cam I22 on one of the shafts H4 gives an intermittent motion to roller I24 which is attached to the pivoted arm I26. A link I28 from the end of that arm is pivotally connected to finger 32. The latter is itself pivoted about a horizontal shaft I30. The intermittent motion of the link causes the finger to strike intermittently in between the belts 30 to deliver a bag down against its tag and the webs 38.

The operation of the device has been described in connection with its parts. i

Since certain changes maybe madein the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all the generic and specific features of the invention herein dewebs II of the packaging, or wrapping material.
