A card inserter for inserting post cards in a series of bound volumes in motion in a production line which includes a pair of horizontally reciprocated feed plates and associated hoppers arranged on opposite sides of a substantially vertical feed plane. A conveyor is provided in the form of a pair of flat endless belts positioned face to face, the belts being trained about a pair of driven pulleys at the inlet end to define a nip at the feed plane as well as pulleys for maintaining the belts in face to face relation along an angular conveyance path. A V-shaped diverter extends downwardly into the nip. The feed plates are reciprocated inwardly and outwardly in synchronism and have one-way frictional driving connection for simultaneous feeding of the lowermost cards against the diverter and thence into the nip so that the cards are delivered to the volume in register with one another. In the preferred form of the invention the feed plates are provided with vacuum ports to which vacuum is applied during the inward motion, and the feed plates are arcuately surfaced to facilitate separation of the lowermost card, with each feed plate having, in addition, a recessed one-way friction roller. Idler rollers on the inlet pulleys provide auxiliary driving nips enabling a shortened stroke of reciprocation. In one embodiment of the invention provision is made for feeding a third card along the feed plane for sandwiching between the first two cards.

Magazine signatures which are manually loaded as a stack into a product hopper are stripped therefrom by conveyor belts and are conveyed as a running shingle having a relatively large setback and a relatively thin vertical cross-section. To assist in establishing such a shingle, lifters periodically raise an upper group of signatures of the stack in the hopper from the lower signatures to reduce the weight on the latter signatures and prevent the lowermost signature from pulling along the immediately overlying signature as the lowermost signature is stripped from the hopper.

Magazines are re-oriented by turning each magazine through ninety degrees in a horizontal plane while the magazine is advanced continuously along a generally straight path. The re-orientation is effected by kicking each magazine laterally while switching control of the magazine from a first continuously moving conveyor to a second continuously moving conveyor which runs alongside the first conveyor.

A presser assembly for a turning conveyor comprises multiple presser rollers that are mounted with the axis of rotation of each roller generally parallel to a radius of the turn and at sufficiently close spacings that each article is pressed against the conveyor by at least one of the presser rollers at all times during its traverse of the conveyance path around the turn. Positive turn-gripping of each article is attained by use of resiliently compressible presser rollers having significant width and which are tapered, sized and canted such that the presser-contact segment of its periphery is parallel to the underlying conveyance surface and moves in the same direction and at the same velocity as the underlying segment of the conveyor, across the full width of the roller, whereby each article is maintained in the same orientation relative to the underlying conveyor throughout the turn. Each of the rollers is mounted for free floating action toward and away from the conveyor surface, and all of the presser rollers are mounted on one vertically adjustable support whereby all are simultaneously adjustable vertically to accommodate articles of significantly different thicknesses.

Magazine signatures which are manually loaded as a stack into a product hopper are stripped therefrom and are conveyed as a rough and non-uniform shingle to an accumulating hopper while being elevated from a low level to a substantially higher level. The signatures are stripped from the accumulating hopper and are formed into a thin and uniform running shingle with a comparatively large setback for transport along a horizontal path to a receiver hopper which is located at a relatively high elevation to feed the collating conveyor of a binding machine. The shingles are fed on an on-demand basis both to the accumulating hopper and to the receiver hopper in order to keep stacks of consistently low height and weight in the hoppers and thereby promote consistent stripping of shingle signatures from the hoppers.

A rotary drum with angularly spaced grippers delivers magazine signatures to the collating conveyor of a saddle stitch binding machine. The signatures are supplied to the drum in the form of a running shingle with successive leading signatures being pulled out of the shingle by successive grippers as the latter rotate through a transfer station.
摘要:
A machine for feeding cards one by one from a vertical stack including a platform for supporting the trailing edge of the stack and a stripper type support for the leading edge corner portion of the stack in the form of a needle having a downwardly angled tip portion extending inwardly under the corner of the stack so that the leading edge of the bottom card rests against the tip portion of the needle. A suction cup is mounted for vertical movement between an upper position in which the cup is in engagement with the bottom card of the stack adjacent the needle and a downwardly retracted position which is below the tip portion of the needle so that the leading edge of the bottom card flicks past the tip of the needle as the card is drawn downwardly. The needle is of hollow construction having a source of pressurized air and the tip of the needle has a longitudinally extending discharge orifice which faces upwardly and which extends both above and below the corner of the stack dividing the orifice into an upper portion and a lower portion. The source of air is at a sufficiently high pressure so that the air from the upper portion of the orifice is forced between the lowermost cards in the region above the suction cup thereby breaking any suction which may exist between the cards and serving as a lubricant for the bottom card facilitating its prompt release from the stack.

A jogger for aligning signatures fed in shingled relation on a delivery belt. The delivery belt is straddled by a pair of upstanding guide belts presenting opposed faces to the edges of the signatures. Each guide belt has an upstream sheave and a downstream sheave mounted on vertical shafts and which are driven in unison with one another and at the same speed as the delivery belt. The guide belts are convergently arranged, with the downstream sheaves being spaced to define between them a discharge opening having the width of the stream in the aligned state. The upstream sheaves are spread apart with respect to the downstream sheaves by substantially the same amount of offset to define a funnel-like entryway adequate to accommodate entry of the stream in non-aligned condition with individual signatures irregularly displaced from the stream. A pulsating shifter is provided behind the presented faces of the belts and coupled to the driving means for repetitively moving the faces from a reference position to a thrown position in which the belts are angularly bowed mutually inwardly toward the stream, dividing each face into an upstream portion and a downstream portion. The throw of the shifter means is such that the downstream portion in its thrown position is substantially parallel to the direction of movement of the stream.
摘要:
An assembling and addressing machine for magazines which are differently assembled in a number of different versions for sending to individuals falling into different demographic categories based upon interest, occupation or the like. A plurality of signatures are produced which are capable, upon selection in predetermined combinations, of accommodating all of the different versions. A gathering device gathers the selected signatures to form a book. Books in various versions are stored in temporary storage stations. The device operates under the control of address labels which include the address and indication of the demographic category. Means are provided for reading the category and for triggering release of a book from the corresponding storage station and to which the label is then applied. It is one of the features of the invention that means are provided in each storage station for sensing depletion and for signaling the gathering device to produce a group of books to replenish the depleted station. The temporary storage stations are in the form of conveyor belts arranged side by side and having hoppers at the output with individual dispensing means. Delay devices, preferably including memory, are interposed between a point where a given book is acted upon and a point of upstream release so that books may flow in unbroken series. Means are provided for calipering each book immediately following gathering of signatures with means for readjusting the caliper depending upon the version of book being measured. Automatic means are provided for insertion of cards into the book at the order of the address label.
