Abstract: Printed products arriving in an imbricated formation are coiled or wound on edge, i.e., with an edge standing upright, onto a revolvingly driven hollow winding cylinder or core. The axis of rotation of this winding core is vertical or is inclined from the vertical. On the underside or bottom side of the winding core there is positioned a co-rotating discoidal support element or plate. The printed products rest or bear with their lowermost edges on this co-rotating support plate. These lowermost edges of the printed products extend substantially transverse relative to the axis of rotation of the support plate. A support strap or element is coiled or wound conjointly with and on the outer side of the imbricated formation of printed products. This support strap or element supports the printed products of the outermost winding or layer of the wound product package or storage coil.
Abstract: Underneath a support table for a cover element or sheet there are positioned a number of receiving or storage bins for additional or supplementary sheets. Between the receiving or storage bins and the support table there is placed a conveyor belt. One run of the conveyor belt is pressed against the underside of the support table. A thrust element for advancing the cover element is coupled with the conveyor belt. A piston-cylinder unit displaces the conveyor belt and the thrust element in a direction of movement towards a deposit device. During this displacement the one run of the conveyor belt rolls at the support table, whereby the conveyor belt is circulatingly driven. A first or active-conveying run of the conveyor belt withdraws additional or supplementary sheets, which have been pushed into the movement path or working range of the conveyor belt, from the receiving or storage bins and transports them towards the deposit device.
Abstract: The cover sheet which is to be placed, is brought into a waiting position above a predetermined conveying path of the stacks of flat articles. The cover sheet is displaced from this waiting position onto one stack by means of a placing element arranged at the end of a piston rod of a piston cylinder unit. The piston-cylinder unit is pivotably mounted about an axis which extends at right angles to a predetermined travel or movement direction of the stack. In its rest position the piston-cylinder unit lies against a pad or buffer which keeps the piston-cylinder unit in an inclined position. By extending the piston rod, the cover sheet is placed onto a stack. The placing element which presses on the stack, is entrained by the further moving stack. Thus the piston-cylinder unit is deflected from its rest position. As soon as a detector detects such a deflecting movement, the detector generates a signal which triggers retraction of the piston rod.
Abstract: An imbricated product subformation is formed from one half of the printed products delivered in an imbricated product formation by a conveyor or transporter. This subformation is guided through a deflection or turning device. The printed products are accelerated and separated or singled as they run through this deflection or turning device and are simultaneously inverted. After leaving the deflection or turning device, the printed products are conveyed against a fixed stop member and are then deposited upon a belt conveyor to form a new imbricated product subformation. A second subformation is formed from the other half of the arriving printed products and is deposited upon the first altered subformation and is then conjointly wound up with this first altered subformation to form a coil or wound product package.
Abstract: Printed products delivered in imbricated product formation by a conveyor having individually releasable grippers are deposited upon a belt conveyor also in imbricated product formation. This imbricated product formation is delivered to a turning device in which the printed products are singled by acceleration and are also inverted. After leaving this turning device, the printed products are conveyed against a fixed stop. After impinging upon this stop, the printed products fall upon a belt conveyor, respectively upon an already formed imbricated product formation. In this imbricated product formation the leading edges are exposed, just as they are in the arriving imbricated product formation. However, the now leading edges are formed by those edges of the printed product which formed the trailing edges in the arriving imbricated product formation. Furthermore, in the newly formed imbricated product formation the originally upper side of the printed products now lies on the underside.
Abstract: The winding station comprises two support wheels rotatably journalled in a frame and which are constructed as friction wheels of a friction wheel drive arrangement. These support wheels are driven by a drive motor through a winding transmission in a common sense of rotation. These support wheels are in inner contact with an annular friction wheel which performs the function of a winding core. This friction wheel comprises a cylindrical rim whose exposed inner surface is constructed as a traction surface by means of which the winding core rests upon the support wheels. Side flanges protrude from the cylindrical rim to laterally delimit the traction surface and serve for lateral guiding. A guide wheel which can be advanced into engagement with the traction surface of the winding core and retracted therefrom is arranged beneath the support wheels.
Abstract: The printed products leaving the product coil or wound package are delivered to an inlet of a conveying channel adjacent to a product transfer or release location of the wound package. A conveying channel is formed by two effectively conveying runs of two belt conveyors. In a section of this conveying channel following this inlet the unwound imbricated formation is inverted. The imbricated formation is subsequently conveyed toward an outlet of the conveying channel where it is transferred to a discharge conveyor. Both belt conveyors are arranged in a pivotable frame construction which is held in contact or coacting relationship with the product coil or wound package by a contact or pressing mechanism. The design of the conveyor arrangement formed by the two belt conveyors permits a compact construction and a free choice of the route of the conveying channel.
Abstract: A first subformation of an arriving imbricated product formation is sub-divided into an initial section, an intermediate section and a terminal section. There is also subsequently formed from the arriving imbricated product formation a second subformation adjunct to the first subformation. These subformations are formed by releasing the grippers of a delivery device at one release point or another. The intermediate section is wound up to form an intermediate coil or wound package, while the initial and terminal sections are first conducted into a branch conveying path. The initial and terminal sections are then adjoined to the front and rear ends of the intermediate section wound off the intermediate coil to complete the first subformation. The initial, intermediate and terminal sections of the first subformation are wound up together with the second subformation to form a storage coil or wound package upon a winding mandrel or core.
Abstract: The printed products unwound from a storage coil or wound package in imbricated product formation are conveyed over two belt conveyors against a stop. According to one embodiment the printed products are separated from the imbricated product formation before reaching the end of the first conveyor device formed by the two belt conveyors by an acceleration imposed by the second of the two belt conveyors, i.e. they are singled. According to another embodiment the imbrication of the printed products is inverted before the products reach the end of the first conveyor device. The individual printed products fall downward after impinging the stop and are deposited upon the preceding printed product in an imbricated formation. The imbricated product formation is conveyed away by a belt conveyor of a second conveyor device in a conveying direction opposite to the conveying direction of the first conveyor device.
Abstract: The winding mandrel comprises a cylindrical winding drum or body which has two circumferential web members on its inner side. Each web member lies substantially in a plane which lies outside the center of gravity of the winding mandrel together with the coil or wound package. The winding mandrel bears upon two driven and tandemly arranged support wheels with one of its web members. A support roll is arranged beneath these support wheels. A lateral support surface of the web member bears against this support roll. The support wheels are constructed as friction drive wheels and, in addition to supporting the winding mandrel, serve to drive the winding mandrel. Due to the overturning or tipping moment induced by the eccentricity of the bearing points of the winding mandrel upon the support wheels in relation to the center of gravity, the winding mandrel is pressed against the support roll. This has the effect that the winding mandrel maintains the desired position during its rotation.
Abstract: The printed products to be wound up are delivered by one belt conveyor of a conveying arrangement. The latter comprises two belt conveyors which conjointly form a conveying channel with a defined inlet and outlet. Conveyor belts of both of these two belt conveyors are guided such that the conveying channel has a curved path directed toward a rotatable winding mandrel. The conveying arrangement is pivotable about an axis of rotation of a drive drum of the innermost conveyor belt of the two conveyor belts and is pressed against the winding mandrel, respectively against the product coil or wound package forming on the winding mandrel, by a winding strap capable of being placed under tension and which is withdrawn from a winding strap supply roll and runs through a portion of the conveying channel and is connected with the winding mandrel. A separate contact or pressing mechanism can be forgone.
Abstract: At a moveable frame there is rotatably mounted a driveable winding core. The one end of a tension-resistant winding band is connected with this winding core, and such winding band is wound-up upon a band spool. This band spool is rotatably mounted in arm members of the frame. Acting upon the shaft of the winding core is a jaw brake. The shaft of the band spool is likewise brakeable and blockable by means of a jaw brake. The frame together with the winding core, band spool and the therebetween traveling winding band can be transported. For winding-up flat products or the like the shaft of the winding core is driven, and the jaw brake effective upon such shaft is opened or retracted. The band spool is slightly braked by the jaw brake associated with the shaft of the band spool. The flat products are infed to a winding gap and together with the winding band which is under tension wound-up upon the winding core.
Abstract: A transport apparatus is arranged downstream of a delivery belt of a rotary printing press. Controlled clamps of the transport apparatus individually entrain the printed products. Three conveyor devices are arranged in sequence in the transport path of the clamps, each of which leads to a driven winding mandrel or arbor. The clamps are opened by suitable control means such that printed products are deposited on each conveyor device in imbricated product formation such that they overlap at their edge regions. The printed products are then wound up to a compact coil or product package on the winding mandrel or arbor in such imbricated product formation.
Abstract: Firstly, a leading first portion of the continuously arriving stream of printed products is stored in the form of an intermediate package present on a winding core journaled for rotation. Subsequently the printed products are again unwound from the intermediate package and joined with a successive second portion of the stream of printed products. In so doing the products in the second portion come to lie in superimposed fashion upon the printed products withdrawn from the intermediate package. Both of the superimposed imbricated product streams are conjointly wound-up upon a rotationally driven winding core to form a primary product package. During exchange of the completed primary product package against a further winding core, the printed products arriving within the period of time needed for this exchange operation are again fed to the intermediate winding core which has now been emptied. These printed products are then wound-up to form an intermediate product package.
Abstract: The two product formations lying in superimposed fashion at a lateral offset are conveyed by a transport device towards a separation or detaching element. The printed products of the first product formation lying at the top marginally protrude at one side thereof past the printed products of the second product formation lying at the bottom. A deflecting part or element of the separation element is arranged in the travel path of the protruding marginal portions of the printed products of the first product formation. The deflecting part or element extends transversely with respect to the travel path. The printed products of the second product formation lying at the bottom run past the deflecting part or element without being acted upon by the latter and are outfed by a first outfeed conveyor.
Abstract: A stack support rotating about an upright axis is arranged beneath a discharge station of a delivery conveyor for the imbricated formation. The stack support and at least the discharge station of the delivery conveyor are adjustable in height in relation to one another. In order to increase the storage capacity of the spiral-layered coiled stack being formed, respectively in order to reduce its height for the same content, a drive mechanism is provided to periodically displace the discharge station of the delivery conveyor and the axis of rotation of the stack support relative to one another periodically and alternatingly toward and away from one another. A spiral-layered coiled stack thus forms in which each layer of the coil consists of a flat spiral preferably comprising a plurality of spiral windings progressing from the interior to the exterior and from the exterior to the interior in alternate layers.
Abstract: A stacking device having at least two stacking wells supplied from above is arranged subsequent to a delivery conveyor for printed products. A deposition apparatus for depositing one cover sheet on each completed stack is also provided. In order not to have to deposit this cover sheet upon the stack just as it leaves the stacking device, a device for preparing individual pre-printed cover sheets is provided. The deposition apparatus includes a cover sheet conveyor arranged subsequent to this cover sheet preparing device. The cover sheet conveyor is provided with a controllable outlet for each stacking well and opens into its associated stacking well.
Abstract: A sensor element and a counter-element are arranged opposite one another on opposite sides of a stream of printed products or the like. The sensor element is a deflecting feeler element. In order to detect multiple occupied positions and still be able to transport the stream of printed products practically without permanent contact by the sensor element in the absence of multiple occupied positions, the counter-element is intermittently advanced toward the side of the product stream opposite the sensor element at the tempo of the sequential or successive continuously transported printed products. The least distance between the undeflected sensor element and the counter-element in its advanced position corresponds to the thickness of one of the printed products or to an integer multiple thereof. A signal generator is associated with the sensor element and responds to its deflection.
Abstract: Printed products arriving in an imbricated product formation are fed to spaced gripper units of a transport device by a belt conveyor. The conveying direction of the belt conveyor forms an acute angle with the transport direction of the transport device. The transporting rate or velocity of the belt conveyor is greater than the transporting rate or velocity by the transport device. Each gripper unit comprises a stationary clamping jaw, a pivotable clamping jaw, and a plate-shaped stop. The pivotable clamping jaw is pivoted against the action of a closing spring by a cam structure or the like. The printed products are first accelerated and then pushed into the open gripper mouth until abutting the stop in order to thereby align the printed products at the region of their leading edges. At the region of their trailing edges, the printed products remain under the conveying action of the belt conveyor at least until the gripper units are closed.
Abstract: A product counter apparatus is disclosed comprising a support element which bears against the products, typically printed products, which are to be counted. A holder device is mounted at the support element. Secured to such holder device is a substantially L-shaped spring or resilient element containing two leg members. The one leg member of such resilient or spring element extends substantially transversely with respect to a predetermined conveying direction of the printed products and protrudes by means of its free end past the holder device. The other leg member of the resilient or spring element is clamped at its end, and thus, can be elastically deflected transversely to a plane containing the printed products. Retained in the holder device is an inductive proximity switch. The printed products moving past the counter apparatus impact at their leading edge at the end of the one leg member which serves as a feeler or sensor and deflect the latter in their product conveying direction.
