Description

The invention relates to a punching machine with a transport system designed as a chain gripper system and a method for opening at least one holding element according to the preamble of claim 1 or according to the preamble of claim 9.

Materials in the form of webs or sheets are used in the manufacture of packaging. In several processing steps, sheets are printed, embossed, creased, perforated, punched, cut, stapled, glued and folded into packaging, for example. For optimal utilization of the area of a sheet, several identical or different copies, e.g. B. a poster, a folding box or packaging, printed on a common sheet and then punched. These specimens are referred to as panels.

A sheet processing machine can include various processing steps such as printing, cutting, embossing, creasing, punching, perforating, gluing and/or stapling. Such sheet processing machines often also have inspection devices. Sheets are usually processed and trimmed in processing machines with form-bound punching and cutting devices.

Such a processing machine is designed, for example, as a punching, cutting, perforating, embossing and/or creasing machine. If such a processing machine is referred to below as a punch and/or punching machine, this also means in particular a cutting, perforating, embossing and/or creasing machine. In the case of form-bound systems, there are also rotary punches Flat dies, in particular flat bed dies. In these, several sheets are processed one after the other by means of a cyclically repeating movement. The sheets are preferably moved largely horizontally through the processing machine using a transport system, preferably a chain gripper system. In addition to a punching unit, such a machine usually also has other units such as B. a sheet feeding unit, a sheet delivery unit, a stripping unit, a sheet insert unit, a blank separation unit and a remnant delivery unit.

Such a sheet processing machine usually has a unit in which a sheet and/or remnant is released and/or detached from the chain gripper carriage. In particular, a chain gripper carriage has at least one holding element for this purpose. The at least one holding element releases the sheets and/or the remnants when interacting with a chain gripper opener.

through the DE 693 07 840 T2 a sheet-fed printing press with a transport system designed as a chain gripper system is known. The sheet-fed printing press has two delivery piles for depositing the processed sheets. The time at which the sheet is released can be adjusted by adjusting a chain gripper opener. In particular, the position of the chain gripper opener is arranged to be adjustable on a straight guide path.

through the EP 1 867 449 A1 a punching machine with a chain gripper transport system is known. In particular, the punching machine has a chain gripper opener for releasing a sheet and/or a remnant. In particular, the chain gripper opener in the ejection station and/or the remnant removal unit can be laboriously adjusted by unscrewing and screwing on.

The DE 42 09 354 A1 discloses a sheet-fed printing machine with a transport system designed as a chain gripper system for the sheets through the machine. The Chain gripper system has chain gripper carriages and multiple holding elements for holding a sheet. The document also discloses a chain gripper opener (curve segment) with a contact surface designed as a run-up area. A control roller is moved to an open position by the chain gripper opener. The chain gripper opener (cam segment) can be adjusted by an adjustment element.

The WO 2018/197046 A1 discloses the preamble of claims 1 and 9 and relates to a device for ejecting sample sheets from a gripper bar of a transport device (chain gripper system) of a processing machine. The processing machine can be designed as a punch. The ejection device comprises an actuating element which has a surface for opening the gripper bar. The profile of the actuating element is curved for this purpose and the rotary drive element ensures that the gripper bar opens upon contact. The actuator is moved from an inactive position to an active position to remove a sample sheet. In production, the actuator is in an active position. The angle of the profile of the actuator can be changed to conform to the substrate. An actuator (drive) interacts with the actuating element via a displacement guide means (linear guide).

The DE 11 41 296 B relates to a gripper control on chain extensions of printing presses. The position of the gripper opening in the horizontal direction is controlled by machine speed, for example. The adjustment is made by means of an electric motor.

The U.S. 5,415,392 A discloses a device for controlling the grippers in a sheet-fed printing press. The sheets are deposited at different locations depending on various parameters (e.g. substrate properties or machine speed). There are areas where the guideway is not horizontal. There the gripper opener can be adjusted on a guide that is attached to the guide path for the Chain gripper is adapted. This means that mechanical loads, noise and impacts on the gripper carriage are reduced.

The US 4,420,998A discloses a punching machine with chain gripper openers with opening sections. The opening angle can be changed (adjustable angle). The invention is based on the object of creating a punching machine with a transport system designed as a chain gripper system and a method for opening at least one holding element.

The object is achieved according to the invention by the features of claim 1 and the features of claim 9 .

An advantage that can be achieved with the invention consists in particular in the fact that an improved and easily adjustable chain gripper opener is created. Preferably, by adjusting the chain gripper opener, the sheet and/or remnant release position can be adjusted in a simple manner along a guide path and the point in time at which the sheet is released during machine operation can thus be changed.

Another advantage that can be achieved with the invention is that the chain gripper opener can be adjusted in a special way. The chain gripper opener can be adjusted along a guide path. In addition, the chain gripper opener can also be easily adjusted on a curved guide path. An opening area of a chain gripper opener is adjusted equidistantly to the guide path, so that no tension and/or loads arise in the machine. Furthermore, the equidistant adjustment prevents vibrations and reduces the maintenance effort. In particular, increased productivity can be achieved with higher machine speeds. For example, due to the increased productivity, the number of chain gripper carriages in of the machine, for example, from nine chain gripper carriages to eight chain gripper carriages.

Another advantage that can be achieved with the invention is that a chain gripper opener can be adapted to different machine speeds and/or different substrate properties and/or different substrate formats and/or different offcut formats. For example, the chain gripper opener can be adjusted so that it opens earlier at a high machine speed and opens later at a lower machine speed. In particular, an accumulation and/or jamming of remnants and/or sheets in the remnant output unit can be prevented in this way.

Furthermore, the at least one chain gripper opener can be adjusted as a function of the substrate format and/or the remnant format. In particular, the sheet and/or the remnant has different formats when it is released from the chain gripper carriage, for example depending on the preceding processing steps and/or the number of blanks. For example, by adjusting the position of the chain gripper opener, the space available and the capacity for transporting away the sheets and/or the remnants can be changed and/or increased and/or improved. In particular, a paper jam and/or an accumulation of sheets and/or remnants can be avoided in this way. In particular, different settings can be stored in a memory and called up automatically, for example, when changing over the sheet processing machine. Based on this, the position of the chain gripper opener can be adjusted automatically.

The at least one chain gripper opener can be adjusted in a simple manner with a structurally simple solution. The at least one chain gripper opener can be adjusted along a guide. In addition, the chain gripper opener is equipped with a Linear guide and a drive adjustable. In addition, the mobility of the chain gripper opener is ensured by a joint and another linear guide.

Exemplary embodiments of the invention are shown in the drawings and are described in more detail below.
