Technical Field

The invention relates to the technical field of textile processing, in particular to a sheet fixing method.

Background

Work operations are usually performed on multilayer sheet-like work materials, for example, in the mass production of garments, the pattern sheet is usually cut from a multilayer fabric which spreads the surface one after the other on a support; to facilitate clean precision cutting, a layer of working material (often called layup) must be adequately held in place on the support surface during the cutting operation; failure to do so can cause the fabric layers to move relative to each other, thereby adversely affecting the performance of the cutting operation;

typically, the blocks are cut from the cut using a so-called cutting table, which generally comprises a permeable, typically conveyor belt, cutting surface and a movable cutting head passing through the support surface, cutting the pattern pieces from the layer of material in response to commands issued from the controller; to eliminate any undesired movement of the layer of working material during the working operation, a vacuum is sometimes used in an effort to pull the working material onto the support surface; in prior art cutting tables, this is typically accomplished by a single centrally located vacuum manifold located below the permeable support surface and defining one or more inlets through which a vacuum is drawn;

a difficulty sometimes encountered when using a single centrally located vacuum manifold is that the portion of the working material located away from the manifold is often not adequately maintained by the vacuum; such insufficient retention can result in movement of the work material during the work operation, as well as producing an inaccurately cut pattern piece; this problem is further exacerbated as the width of the cutting station increases, for which a sheet fixing method is proposed.

Disclosure of Invention

The present invention is directed to a sheet fixing method to solve the above problems of the background art.

In order to achieve the purpose, the invention provides the following technical scheme: a sheet fixing method includes the following steps:

s100, providing a device having a permeable support surface connected to a frame, a controller in communication with the device for storing data in a machine readable format corresponding to a work operation to be performed on a work material, at least two vacuum manifolds connected to the frame and spaced relative to each other, each manifold defining at least one vacuum inlet, and means for drawing a vacuum through the inlets and the permeable support surface;

s200, providing at least one layer of sheet-shaped working materials on a supporting surface;

s300, according to a command sent by a controller, vacuumizing is performed through an inlet and a manifold so as to keep the sheet-shaped working material on the supporting surface;

s500, in response to a command issued from the controller, the intensity of the vacuum is scaled relative to the inlet and each manifold such that the intensity of the vacuum is maximized in the adjacent area during performance of the work operation.

Compared with the prior art, the invention has the beneficial effects that:

1. each vacuum manifold defines at least one vacuum inlet through which a vacuum device draws a vacuum through the permeable support surface to hold the work material thereon. This prevents any undesired movement of the work material relative to the support surface during the performance of the work operation;

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b):

the invention provides a sheet fixing method as shown in fig. 1, which comprises the following steps:

s100, providing a device having a permeable support surface connected to a frame, a controller in communication with the device for storing data in a machine readable format corresponding to a work operation to be performed on a work material, at least two vacuum manifolds connected to the frame and spaced relative to each other, each manifold defining at least one vacuum inlet, and means for drawing a vacuum through the inlets and the permeable support surface;

s200, providing at least one layer of sheet-shaped working materials on a supporting surface;

s300, according to a command sent by a controller, vacuumizing is performed through an inlet and a manifold so as to keep the sheet-shaped working material on the supporting surface;

s400, responding to a command sent from a controller, and executing work operation on a work material;

s500, in response to a command issued from the controller, the intensity of the vacuum is scaled relative to the inlet and each manifold such that the intensity of the vacuum is maximized in the adjacent area during performance of the work operation.

In this embodiment, specifically: further comprising a plurality of vacuum conduits, each vacuum conduit connected to one of the manifolds adjacent to one of the inlets, a plurality of butterfly valves, each butterfly valve located within and pivotably connected to one of the conduits for movement between open positions, wherein vacuum can be drawn freely through the conduits and prevented from drawing vacuum through the conduits, and a plurality of pneumatic cylinders, each cylinder pivotably connected at one end to the frame and connected at an opposite end to one of the ratios.

In this embodiment, specifically: the step of proportionally adjusting the vacuum intensity further comprises selectively actuating the pneumatic cylinder to move at least one of the butterfly valves between the open position and the closed position to adjust the vacuum intensity at the manifold and the inlet in response to commands issued from the controller.

In this embodiment, specifically: the permeable support surface is defined by a plurality of slats arranged in series and connected together, the slats overlying and being supported by each of the manifold sections. The permeable support surface includes a plurality of slats, each slat overlying and supported by the vacuum manifold and extending transversely across the frame. The slats are movable in the longitudinal direction of the frame in response to commands issued from the controller by means of a suitable drive, for example an electric motor. A plurality of bristle blocks are connected to each slat, each slat defining a plurality of upstanding bristles for supporting a working material thereon.

In this embodiment, specifically: moving the plurality of slats in a longitudinal direction of the frame such that the plurality of slats convey the work material onto or off of the support surface in response to commands issued from the controller.

In this embodiment, specifically: the means for drawing a vacuum from the inlet and the permeable support surface comprise a vacuum pump.

In this embodiment, specifically: the means for drawing a vacuum amount from the inlet comprises a plurality of proportional control valves, each of said inlets connected to one of said inlets being movable in response to commands issued from said controller such that each inlet is between an open position in which vacuum can be drawn freely through said inlet and a closed position in which vacuum is prevented from being drawn through said inlet.

The working principle is as follows: in use, during operation, one or more layers of working material are positioned on the permeable support surface. By energizing the vacuum pump and selectively actuating the pneumatic cylinders, a vacuum is drawn through the inlet defined by the manifold. The butterfly valve is moved between an open position and a closed position in response to a command from the controller. The vacuum pulls the work material toward the support surface, preventing any undesired movement of the workpiece. The support and tool tip are then moved over the work piece material to cut the pattern. The controller issues commands to the pneumatic cylinder when the pattern piece is being cut.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
