Abstract
Description
- This invention relates to business forms handling equipment suitable for business offices, and more particularly, to an apparatus for conveying and sealing collated form sheets into form sets.
- Continuous business form assemblies have long been considered desirable for mass mailings and the like. High speed printers have been used for both custom and non- variable printing of such assemblies. However, certain desirable high speed printers print with toners which are set or fixed by heat. Such printers are incompatible with form assembly constructions having heat sealable adhesives. The assembly webs having the heat sealable adhesives cannot be fed through the printers or other heat generating equipment because otherwise the webs would prematurely, undesirably, adhere to the equipment mechanisms. As a result, the webs of such assemblies having adhesive must be assembled or collated with the printed webs after printing.
- Yet with this sequence of assembly, sheet length differentials occur between the sheets of the adhesive coated webs, and the printed webs. The heating of the printed webs during the setting of toners dries the sheets of the printed webs, compounding a sheet length mismatch. Further, standard sealing equipment cannot accommodate a two ply collated form.
- An object of the inventors which led to the making of this invention was to provide business form sealing equipment capable of consistently, continuously collating and sealing form sheets of matched and mismatched form sheet lengths.
- Another object was to provide such equipment of a compactness, reliability and ease of use suitable for typical business offices and personnel.
- The invention provides such sealing equipment, and proceeds, in part, with a reversal of sealing and detaching functions of standard sealing equipment. Form sheets are collated first, which allows sheet length differences to be accommodated, then detached from their webs, and then sealed. The invention also incorporates the conveying of the sets of sheets being sealed in an overlapped or shingled manner.
- The present invention is an apparatus for conveying and sealing collated form sheets into form sets, at least one of the form sheets for each set having heat sealable adhesive and wherein the apparatus comprises a base, heating means and conveying means on the base. The heating means constitutes means for heating the heat sealable adhesive to seal form sheets of the group together. The conveyor means constitutes means for conveying the groups of form sheets through the heating means. The conveyor means includes means for aligning the form sheets of the groups before the groups enter the heating means.
- The preferred embodiment of the invention will be described by way of example in relation to the accompanying drawing, which consists of four views, or figures, wherein:
- FIG. 1 is a perspective view of the preferred embodiment with the infeed portion to the upper left;
- FIG. 2 is a side elevation view of the preferred embodiment, with the frame partially cut away to reveal internal detail;
- FIG. 3 is a top or plan view of the preferred embodiment, with the partial cover shown in FIGS. 1 and 2 removed to reveal internal detail; and
- FIG. 4 is a cross-section view taken along line 4-4 of FIG. 3.
- Referring to FIG. 1, the preferred embodiment of the present invention is a sealer/conveyor 10 adapted to operate on 110 Volt current and rest atop feet such as
foot 11 on amobile stand 12, for general office use. The sealer/ conveyor 10 includes a base orframe 14,heating structure 16, infeedconveyor structure 18,output conveyor structure 20, andstacking rack 22. Form sheets are fed in groups on the infeedconveyor 18 through theheating structure 16, where they are sealed into form sets, then fed onto theoutfeed conveyor 20, and stacked against therack 22. - As shovn only in FIG. 1, the infeed
conveyor structure 18 includes an infeed conveyor of a plurality of conveyor belts such as belt 24 stretched about pulleys such aspulley 26 on pulley shafts such asshaft 28. - Also as shown only in FIG. 1, a plurality of alignment or
nip rollers 30 are mounted to thebase 14, above theconveyor structure 18. Therollers 30 are adapted to be friction driven by the infeed conveyor belts.Pivotable links 32 provide for rotation of therollers 30 about their central axes, and pivoting of therollers 30 about a shaft 34. The shaft 34 slides within slotted support brackets 36, for adjustment of the distance of therollers 30 to the outermost end 38 of the infeed conveyor structure. - The sealer/conveyor 10 is usable with a detacher, a collator, or similar machines, for receiving form sheets from such equipment on the conveyor belts of the infeed conveyor. The infeed conveyor belts are driven to provide a form speed substantially less than that of an associated detacher or the like. The sealer/conveyor is attached by
frame hooks 35 to the associated equipment. Form sheets, whether matched or mismatched, are deposited on the infeed conveyor belts 24. Where mismatching is expected, therollers 30 are adjusted to be sufficiently close to the infeed end 38 that the distance from the end rollers of the detacher or the like to therollers 30 is less than one form length. - As a result of the conveyor speed and position of the
rollers 30, form sheets of a form set arriving mismatched at therollers 30 are jogged or slid relative to each other into alignment. - In more detail, where a plurality of mismatched form sheets are driven onto the conveyor belts 24, the leading edge of the form sheet which is first to arrive at the
rollers 30 will be slowed to the speed of the belts 24 androllers 30, at the nip of the belts 24 androllers 30. Remaining form sheets, the leading edges of which have not arrived at therollers 30, continue to be driven at higher speed to therollers 30. As the leading edge of each remaining form sheet arrives at the nip of the belts 24 androllers 30, the leading portion of each form sheet is slowed, and each leading edge is substantially aligned or matched with the leading edge of the first arriving sheet. - The aligned form sheets continue to move, at the reduced speed of the belts 24 and
rollers 30, into theheating structure 16. As form sheets of further form sets arrive at therollers 30, these further form sheets overlap the trailing portions of the form sheets of preceding form sets. The sealer/conveyor 10 accommodates such overlapped or shingled form sets, which remain shingled until racked. - The overlapped form sets move at the speed established by the infeed
conveyor structure 18 into theheater structure 16. As shown in FIGS. 2-4, theheater structure 16 includes vertically spaced upper andlower heating platens roller 44 include roller segments such as 46 on shafts such as 48. The roller segments extend through cut-outs in the platens, to drive the shingled form sets through theheating structure 16, between theplatens - As shown in FIG. 2, the platen rollers include idler rollers in the
cover 52 of theheating structure 16, and driving rollers driven by achain drive 50 from amotor 54. Themotor 54 drives ashaft 56 of theoutput conveyor structure 20, which drives sprockets such assprocket 58 mounted along the shafts of the driving platen rollers. Theshaft 56 andsprocket 58 are portions of thedrive 50. - The
platens heating structure 16 is equal to the speed of the infeedconveyor 18, while the number of form sets through the heating structure per unit time is determined by the speed of the detacher or other associated equipment. As an example, each form may travel through theheating structure 16 at an infeed conveyor speed of thirty feet per minute, while the form sets may accumulate on the sealer/conveyor at a detacher speed of up to sixty feet per minute. The length and temperature of theplatens platens - As most preferred, the
platens platens - The resulting sealed form seta exit the
heating structure 16 onto an output conveyor of a plurality of output conveyor belts such as 60 stretched about pulleys such as 62, as shown in FIG. 1. The output conveyor belts are driven at the same speed as the input conveyor belts. At the terminal end of theoutput conveyor structure 20, the form sets are driven onto therack 22. Since the form sets remain shingled on the output conveyor belts, each form set acts as a guide for movement of following form sets onto therack 22. The form sets remain stacked upon therack 22, in condition for use, until manually removed.
