Definitions
- references Ci d multi-bag packaging section includes two laterally but UNn-ED STATES PATENTS oppositely disposed collection boxes between which is located a mechanical diverter.
- the present invention relates to an improved, high speed bag-folding and packaging machine particularly designed to handle sheet or flat plastic materials, although other equivalent sheet materials may be processed, such as are used for plastic bags.
- the function of the machine is to receive the discharged bags from a bag-making machine at any given rate and to automatically process, fold and package the bags so that they are ready for commercial distribution.
- the present invention is directed to an improved high speed version of the bag folding machine and method disclosed in my prior, copending application entitled Machine And Method For Folding Plastic Bags And The Like, Ser. No. 92,087, filed Nov. 23, 1970, being issued as U.S. Pat. No. 3,671,033, June 20, 1972, and in particular is directed to an improved means of removing the bag from the roller section of the bag folding machine.
- my prior, copending application entitled Machine And Method For Folding Plastic Bags And The Like, Ser. No. 92,087, filed Nov. 23, 1970, being issued as U.S. Pat. No. 3,671,033, June 20, 1972, and in particular is directed to an improved means of removing the bag from the roller section of the bag folding machine.
- the present invention does this by, broadly speaking, substituting for the moving pin a centrally located air jet ejecting means, which by a jet or blast of air blows the bag out of the rolling section. It thus can operate much more rapidly.
- the present invention utilizes a different, improved multi-bag packaging section which includes two separate bag collection sections with a mechanical diverter which allows the final packaging to be carried on independently of the collection function, further enhancing the speed handling capability of the machine.
- the present invention is particularly useful when folding small bags which are relatively easily blown out of the rolling section, and is inherently simpler in structure and correspondingly more reliable and cheaper to build.
- FIG. 1 is a right, side view of the major working portion of the complete machine of the present invention, showing a part of the conveyor belt assembly and the rolling, folding and multi-bag packaging sections;
- FIG. 2 is an end view, partially in cross-section (along section lines 22 of FIG. 1), of the rolling, folding, and multi-bag packaging sections, showing a bag being blown out of the rolling section into the folding section;
- FIG. 3 is a perspective view of the diverter system used to guide the folded bags to one of the two collection boxes in the multi-bag packaging section;
- FIG. 4 is a cross-sectional view (along section iines 44 of FIG. 2) of the air jet ejector which blows the bag out of the rolling section into the folding section.
- the preferred embodiment of the present invention is a high speed machine for taking plastic bags, ultimately folding them flat, and packaging a certain number of the folded bags into boxes in a positive, continuous and automatic manner.
- a discharged bag from a bag-making machine is fed into an upper 101 and lower 102 set of continuous or endless conveyor belts running in contact with each other at the same surface speed, each set consisting of eight twoinch-wide belts.
- the bag is held firmly between these belts and conveyed tothe rolling section of the machine.
- the belts 101, 102 are driven by drive rolls 105, 106, respectively.
- conveyor belts 101 and 102 and rollers 105 and 106 hereof are functionally and structurally the same as elements 1, 2, 5 and 6, respectively, of the prior application.
- the belts 101, 102 are supported by suitable idler rollers conveniently placed along the belt path as desired and are driven by a suitable sprocket drive system. Belt tension is maintained on the belts 101, 102 by spring loaded tensioners, each belt having independent tensioners.
- the belt sections 101, 102 feed the flat, unfolded bag into a group of intermeshing or interdigitating, driven rollers 112 whose surface interaction with the bag cause it by a positive driving action to be wound into a roll 100.
- the axes of the rollers 112 are disposed about 270 of a circle, leaving an opening into the bag rolling section into which the belt sections 101, 102 feed the bag.
- the peripheries of the rollers 112 facing inwardly into the circle thus define a generally circular, moving surface which drives the bag around into a roll.
- Driving force is transmitted to the bag by friction between the rubber surface of the rollers 112 and the bag itself. Also the belts 101, 102 push the bag into the rollers 112.
- rollers 112 Although the axes of the rollers 112 are shown disposed in a precise circle, merely a curved disposition is satisfactory. Moreover, although approximately two hundred and seventy degrees of the curved rolling section formed by rollers 112 has been illustrated, it is possible to get a rolling section with much less coverage. It is only necessary to supply sufficient coverage so that the bag would have a tendency to roll back upon itself and form a roll as it proceeds into the rolling section. As a normal rule it will usually require at least 180 of coverage to properly form a roll.
- the rollers 112 thus form in effect a laterally and horizontally disposed cul-de-sac having an inner moving surface for driving the bag into a roll.
- a laterally and horizontally disposed cul-de-sac having an inner moving surface for driving the bag into a roll.
- the rolling section could be formed of a continuous curved belt system.
- Centrifugal force, bag material stiffness and the increase in the bag diameter as it is being rolled contribute to the normal force which holds the bag against the drive rollers 112 surface and positively guide it to its rolled condition.
- the surface speed of rollers 112 is usually designed to be twenty-to-thirty per cent greater.
- the rollers 112 have alternating protruding sections which interdigitate or intermesh with the adjacent rollers, as best shown in FIG. 2. This can be achieved by placing alternating rubber sleeves on the roll shafts as shown. The degree of interdigitation or intermeshing can be controlled by varying the sleeve width, diameter, spacing and thereby the amount of overlap or intermesh. Friction characteristics of the system can of course be varied by changing the sleeve material and hence its properties.
- rollers 112 are driven at the same speed, their speed could be different. Particularly each roller 112 could be run at a higher speed than its immediate neighbor so that the last roller to touch the bag will be running at a higher speed than the initial roller. 7
- the rollers 112 do not extend the full width of the machine but rather are centrally gaped, that is, they are divided into two equal, separate but interconnected side sections.
- the central region between the central supports of the side sections of the rollers 112 is thus basically open.
- the rolled bag 100 in the present invention is blown out by means of a horizontally disposed, downwardly directed air jet ejector which includes an extended or elongated nozzle 113 fed by air line 114.
- a horizontally disposed, downwardly directed air jet ejector which includes an extended or elongated nozzle 113 fed by air line 114.
- compressed air is supplied through line 114 to nozzle 113.
- Flow from the nozzle 113 is directed down at the bag 100, driving the bag 100 down into the initial rollers 115 (note FIG. 2).
- the nozzle 1 13 is constructed to produce a thin eIon-. gated line of air which has a knifing effect as the air im- I pinges on the bag 100 and extends substantially across the width of the rolling section. As shown in FIG. 4, this is accomplished by discharging the air from the nozzle 113 through an extended line of small orifices 129, or alternatively through a continuous thin slot (notillus trated). Internally to the nozzle 113 the orifices-129 are joined together by a lateral chamber 128 which through central line 127 and coupling 126 is connected to air line 114.
- the diverter 121 is generally speaking triangular in cross-section but has curved sides. As best shown in FIGS. 2 and 3, the selected di 7 version is accomplished by swinging or pivoting the diverter 121 about shaft 122. Force to move the diverter 121 is provided by air cylinder 125 which pushes or pullslink 124 which is connected to arm 123 as shown. Nips 116 and 117 or 116 and 117 further crease the bag and drive the bag into collection box 120 or 120",
- rollers 115, 115', 116, 116', 117 and ll7" are all driven in the directions indicated (note arrows in FIG. 2) by means of a gearbox 118.
- Motor 119 drives the gearbox 118 at the desired speed.
- the surface speed of rollers 116 and 116 is equal to or greater than the SUI? face speed of rollers 115 and 115'.
- the I relatively rigid type of material such as paper could be driven into a system of static circular guides to thereby form a roll.
- plastic bag or sheet material having practically no rigidity, does not consistently wor with such prior art machines.
- the present invention provides, not a static guide
- the two particular embodiments disclosed ofthe present invention for the rolling section namely, a set of driver rollers circularly disposed and a continuous driven belt having a circular section, provide a positive, dynamic carrying and driving of the bag into a tubular roll.
