A sheet delivery unit has at least one rear sheet stop. The sheet delivery unit has at least one forward stack limiter. The sheet delivery unit has at least one upper sheet transportation system, designed for hanging transportation of sheets, with at least one imbrication device for the imbricated, hanging transportation of at least two sheets. A sheet processing machine is also disclosed. A method is disclosed for operating a sheet processing machine. Processed substrate in the form of a sequence of sheets spaced apart from one another in a transportation direction, is supplied in this transportation directed to a sheet delivery unit of the sheet processing machine. At least during a sheet braking procedure, at least at times, at least two sheets are guided in a hanging manner by the use of an upper sheet transportation system, configured for the hanging transportation of sheets, of the sheet delivery unit, and are transported in an imbricated arrangement at least also in the transportation direction.
A sheet delivery unit (1000), wherein the sheet delivery unit (1000) has at least one rear sheet stop (03), and wherein the sheet delivery unit (1000) has at least one forward pile limiter (04), and wherein a delivery pile area is delimited at least by the at least one rear sheet stop (03) and the at least one forward pile limiter (04), and wherein the sheet delivery unit (1000) has at least one upper sheet transport system (06) configured for the hanging transport of sheets (02), which has at least one imbricating device (46) and at least one sheet infeed means (08) configured as an upper suction transport means (08), and at least one sheet decelerating means (07) configured as an upper suction transport means (07), and wherein the at least one imbricating device (46) serves to produce imbrication for an imbricated, hanging transport of at least two sheets (02) at at least one point located above the delivery pile area as viewed in the vertical direction (V), characterized in that the sheet delivery unit (1000) has at least one dropping means (32), which can be moved between at least one standby position and at least one dropping position, and in that, in the at least one standby position of the at least one dropping means, the at least one dropping means (32) is positioned fully above a part of a transport surface (22) of the at least one sheet decelerating means (07) that contributes to establishing a transport path provided for the transport of sheets (02), and in that, in the at least one dropping position of the at least one dropping means, the at least one dropping means (32) protrudes at least partially downward to a point below said part of the transport surface (22) of the at least one sheet decelerating means (07).
A sheet delivery unit (1000), wherein the sheet delivery unit (1000) has at least one rear sheet stop (03), and wherein the sheet delivery unit (1000) has at least one forward pile limiter (04), and wherein a direction of transport (T) is a horizontal direction (T) that is oriented from the forward pile limiter (04) toward the rear sheet stop (03), and wherein the sheet delivery unit (1000) has at least one upper sheet transport system (06) configured for the hanging transport of sheets (02), which comprises at least one sheet infeed means (08) configured as an upper suction transport means (08) and at least one sheet decelerating means (07) configured as an upper suction transport means (07), and wherein the at least one sheet infeed means (08) is arranged at least partially upstream of the at least one sheet decelerating means (07) with respect to the direction of transport (T), and wherein at least one downwardly acting, activatable displacement element (12) is arranged such that a displacement region of the at least one downwardly acting, activatable displacement element overlaps at least partially with respect to the direction of transport (T) with a transporting section, determined by the at least one sheet infeed means (08), of a transport path provided for the transport of sheets (02) characterized in that the sheet delivery unit (1000) has at least one dropping means (32), which can be moved between at least one standby position and at least one dropping position, and in that in the at least one standby position of the sheet delivery unit, the at least one dropping means (32) is positioned fully above a part of a transport surface (22) of the at least one sheet decelerating means (07) that contributes to establishing a transport path provided for the transport of sheets (02), and in that, in the at least one dropping position of the at least one dropping means, the at least one dropping means (32) protrudes at least partially downward to a point below said part of the transport surface (22) of the at least one sheet decelerating means (07).
A method for operating a sheet processing machine (01), wherein processed substrate (02) in the form of a sequence of sheets (02) spaced apart from one another in a direction of transport (T) is fed in this direction of transport (T) to a sheet delivery unit (1000) of the sheet processing machine (01), and wherein, at least during a sheet decelerating process, at least two sheets (02) are guided, at least temporarily, in a hanging state by means of an upper sheet transport system (06) of the sheet delivery unit (1000), configured for the hanging transport of sheets (02), and are transported in an imbricated arrangement, at least also in the direction of transport (T), and wherein the sheets (02) are each transported in a hanging state by means of at least one sheet infeed means (08) of the sheet delivery unit (1000), configured as an upper suction transport means (08), and are transferred by said sheet infeed means to at least one sheet decelerating means (07) configured as an upper suction transport means (07), and wherein in a displacement process, a respective trailing end (29) of a respective leading sheet (02) is forced downward away from the at least one sheet infeed means (08) by means of at least one displacement element (12), characterized in that the respective process of decelerating a respective sheet (02) begins before the respective process of displacing said sheet (02) begins.
A method for operating a sheet processing machine (01), wherein processed substrate (02) in the form of a sequence of sheets (02) spaced apart from one another in a direction of transport (T) is fed in this direction of transport (T) to a sheet delivery unit (1000) of the sheet processing machine (01), and wherein the sheets (02) are each transported in a hanging state by means of at least one sheet infeed means (08) of the sheet delivery unit (1000), configured as an upper suction transport means (08), and are each transferred by said sheet infeed means to at least one sheet decelerating means (07) configured as an upper suction transport means (07), and wherein in a displacement process, a respective trailing end (29) of a respective leading sheet (02) is forced downward away from the at least one sheet infeed means (08) by means of at least one displacement element (12), and wherein in a sheet decelerating process, this respective leading sheet (02) is decelerated by means of the at least one sheet decelerating means (07), and wherein in an imbricating process, a respective leading end (31) of a respective succeeding sheet (02) is pushed between the trailing end (29) of the respective leading sheet (02) on the one hand and the at least one sheet infeed means (08) on the other, with respect to a vertical direction (V), while the respective leading sheet (02) is still partially held by the at least one sheet decelerating means (07), and wherein in a detachment process, the respective leading sheet (02) is detached completely from the at least one sheet decelerating means (07), and wherein in a stacking process, the respective sheet (02) that has just been detached is deposited downward from the at least one sheet decelerating means (07) onto a delivery pile (28), characterized in that the respective process of decelerating a respective sheet (02) begins before the respective process of displacing said sheet (02) begins.
