Problems solved by technology

[0006] In all cases, increasing the speed of the machine results in faster mechanical movement of the suction cups
However, the current problem is that when the system is set to operate at very low and very high speeds, it can cause the suction cups to advance too late or return to position too early

Embodiment Construction

[0054] For the sake of clarity, the same elements are denoted by the same reference numerals. At the same time, only elements essential for understanding the invention are shown, which are not shown to scale in a schematic manner.

[0055] portrait, vertical and landscape orientations in Figure 4 is represented by an orthogonal space system (L, V, T).

[0056] figure 1 A sheet material processing machine 100 is shown, such as a printing press, die cutter or foil stamping machine.

[0057] The board processing machine 100 allows converting board elements into packaging, for example cardboard packaging. The stamping machine 100, typically comprising a plurality of workstations 110, 120, 130, 140, 150, are arranged side by side to form a monolithic assembly capable of processing a series of flat elements. Therefore, it is necessary to provide an infeed 110 to supply the sheets individually to the machine 100, an infeed table 120 for placing the sheets in layers before precis...

Abstract

The invention relates to a board working machine comprising a gas and / or vacuum distribution device. The gas and / or vacuum distribution device comprises: -at least one controllable pilot valve, -a stationary body comprising: -at least one main gas inlet connected to a gas or vacuum source, -at least one main gas outlet connected to at least one suction cup and / or at least one nozzle, - at least one first and one second control gas opening, at least one of which is connected to a controllable pilot valve, at least one housing comprising a first chamber and a second chamber , -at least one movable piston is movable between the following positions: a closed position, in which the movable piston blocks the gas passage, and an open position, in which the movable piston releases the gas passage, the first and second The two chambers are isolated from each other. The invention also relates to a method of guiding a gas and / or vacuum distribution device of a board working machine.

Description

technical field [0001] The invention relates to a gas and / or vacuum distribution device for a board processing machine. The invention also relates to a suction unit and a feeder comprising such a gas and / or vacuum distribution device. The invention also relates to a board processing machine comprising the feeder or the gas and / or vacuum distribution device, and a method of guiding the gas and / or vacuum distribution device. Background technique [0002] Board processing machines allow converting boards (e.g. cardboard) into packaging. This operation involves applying decorative or informational printing to the paperboard and cutting it to form the packaging. For this, cardboard is cut into short boards. The boards are stackable and easy to handle, and can be fed into the board processing machine one by one. Sheet processing machines typically consist of a pair of tools, such as cutting or printing rolls or platens, operating at extremely high speeds, with sheets being fed...
