Description

Adsorption type positioning device

Technical Field

The invention relates to a positioning device, in particular to an adsorption type positioning device suitable for a cutting machine.

Background

Referring to fig. 1, a conventional cutting machine 1 mainly includes a plane 11 on which a material unit 2 is placed, and a cutting device 12 for cutting the material unit 2. The plane 11 has a plurality of air holes 111 communicating with a negative pressure device (not shown). The air holes 111 are used for generating an adsorption force with respect to the bottom surface of the material unit 2 in a negative pressure state, so that the material unit 2 can be stabilized on the plane 11. The cutting device 12, such as a laser, a cutter, etc., is used to cut the material unit 2 into more than one piece of fabric with a predetermined shape.

Although the cutting machine 1 may generate the suction force for sucking the material unit 2 through the air hole 111, when the material unit 2 includes a plurality of stacked materials 21, only the lowermost material 21 may be sucked and positioned, and particularly when the material 21 is an airtight material, it is easy to affect the cutting accuracy or cause cutting interruption due to floating or throwing away caused by partial disconnection during the cutting process.

In order to reduce the problem of floating and throwing away of the material 21, another manufacturer covers a release paper or an adhesive film above the material unit 2 to construct a space which can cover the whole material unit 2 and is in an airtight state, and it is desired to improve the overall absorption effect, however, when the release paper or the adhesive film is also damaged as the material 21 is cut, the airtight state is immediately released, and there is also a disadvantage that the material 21 floats and is thrown away, and the thrown away portion is wound around the cutting device 12, which causes cutting interruption.

Detailed Description

Referring to fig. 2 and 3, an embodiment of the suction positioning device of the present invention is suitable for being installed on a cutting machine 3. The cutting machine 3 is adapted to cut a material unit 4 and comprises a cutting device 31. In this embodiment, the cutting device 31 performs cutting by laser. The material unit 4 comprises a plurality of materials 41. The material 41 is stacked in a stacking direction Z and extends in an extension direction X and through the cutter 3. The stacking direction Z is at a perpendicular angle to the extension direction X. The adsorption type positioning device comprises a platform 5, a pressure rod unit 6 and two pressure plate units 7.

The platform 5 defines a chamber 50 (fig. 5) and includes a chamber wall 51 surrounding the chamber 50. The chamber 50 (fig. 5) is adapted to communicate with a negative pressure device (e.g., a vacuum pump, not shown). The chamber wall 51 has a mesa 511 and a plurality of air holes 512 formed on a top surface. The table 511 is adapted to carry the material unit 4. The air hole 512 penetrates the table 511 and communicates with the outside and the chamber 50.

The pressing rod unit 6 is disposed on the table 511 of the platform 5, and includes two rails 61 and a pressing rod 62. The rails 61 are spaced apart by a distance in an axial direction Y of the strut 62. The axial direction Y is perpendicular to the extension direction X and the stacking direction Z. The pressing rods 62 are arranged between the rails 61 in a displaceable manner along the stacking direction Z and define a feeding space 620 with the table 511. The feeding space 620 is adapted for passage of the material units 4 along the extension direction X.

In the present embodiment, the pressing rod 62 is locked between the rails 61 by bolts (not shown), and the material units 4 with large thickness variation can smoothly pass through the feeding space 620 by changing the height of the feeding space 620 along the stacking direction Z. It should be noted that the pressing rod 62 is not limited to be locked between the rails 61, and in the modified example of the present embodiment, the rails 61 may be omitted, and the pressing rod 62 is driven to displace along the stacking direction Z by two pressing cylinders disposed on the table top 511, but not limited thereto.

The platen units 7 are spaced apart by a distance along the axial direction Y, and each platen unit 7 includes a slide member 71, a platen 72, and a guide member 73.

The slider 71 is displaceably positioned in the axial direction Y on the plunger 62 and has a first engagement portion 711, a second engagement portion 712, and a plug portion 713. The first engagement portion 711 extends in the extending direction X. The second connecting portion 712 is formed in a reversed-U shape and is disposed across the pressing rod 62. The insertion part 713 is disposed on the first engagement part 711 and extends along the stacking direction Z.

The pressing plate 72 has a first insertion hole 721, a covering portion 722, and a pressing portion 723 formed at one end. The pressing plate 72 is sleeved on the insertion part 713 of the sliding member 71 through the first insertion hole 721. The covering part 722 is adjacent to the pressing part 723 and is formed on two sides of the pressing part 723 along the extending direction X, and one side of the covering part 722, which is far away from the pressing part 723, is attached to the table top 511. The pressing portion 723 is adapted to fit to one side of the material unit 4.

The pressing plate 72 is made of a material having flexibility, resilience, and deformation resistance, such as PVC, paper, etc., and defines a channel 720 (see fig. 6) communicating with the corresponding air hole 512 with the table 511 and the side of the material unit 4.

The guiding member 73 is connected to the second engaging portion 712 of the sliding member 71, and has a supporting portion 731 and a position-limiting portion 732 with an angle. In this embodiment, the supporting portion 731 and the restricting portion 732 form a vertical angle. The support portion 731 is adapted to be supported on the bottom surface of the material unit 4. The position-limiting portion 732 is adapted to face a side surface of the material unit 4, and adapted to allow the side surface of the material unit 4 to abut against.

When the material unit 4 is driven in the direction of the arrow shown in fig. 2 and moves along the extending direction X along the table surface 511 of the platform 5, referring to fig. 4, fig. 5, fig. 6 and fig. 7, the material unit 4 is guided by the position-limiting portion 732 of the guiding member 73 during the moving process, and passes through the feeding space 620 to be located below the cutting device 31.

During the process of cutting the material unit 4 by the cutting device 31, the chamber 50 of the platform 5 sucks air by the negative pressure device (not shown), so that the air flow enters the chamber 50 from the bottom surface of the material unit 4 through the air holes 512 as shown in fig. 7, enters the channel 720 from the side surface between the materials 41 of the material unit 4, and enters the chamber 50 from the channel 720 through the air holes 512, thereby forming a negative pressure state between the chamber 50, the air holes 512, and the channel 720, and generating an adsorption force with respect to the materials 41 of the material unit 4, so that the materials 41 adjacent to the upper and lower sides of the material unit 4 are closely arranged together and adsorbed on the table 511.

When the material 41 is cut and partially broken, the air flow enters the material 41 from the broken portion, then enters the channel 720 from the material 41 through the side surface, and finally enters the cavity 50 from the channel 720 through the air hole 512. Thereby, an adsorption force can be generated with respect to the material 41 of the material unit 4, so that the material 41 adjacent to the material unit 4 is closely arranged and adsorbed on the table 511.

Referring to fig. 6 and 8, it is worth explaining that, since the pressing plate 72 is made of a material having softness, and is fitted over the insertion part 713 of the slider 71 through the insertion hole 721, and therefore, when the thickness of the material unit 4 is slightly changed and the end of the pressing plate 71 passes under the pressing portion 723 along the extending direction X, the pressing plate 72 is pushed by the material unit 4 or, due to its own weight, is displaced in the stacking direction Z following the insertion part 713, the distance and height between the pressing plate 72 and the table 511 are automatically adjusted, and the pressing plate 72 can naturally drop the covering part 722 to be contacted with the table 511 and the pressing part 723 to be pressed on the material unit 4 through the flexibility of the pressing plate 72, while it is equally possible to define with the table 511, the side of the material unit 4, a channel 720 communicating with the corresponding air hole 512.

It should be noted that the covering portion 722 of the pressing plate 72 of each pressing plate unit 7 is not limited to be naturally dropped to contact with the table top 511, and in other variations of the present embodiment, the pressing plate 72 may be a resilient and non-deformable plate material having flexibility and being connected to the table top 511. As shown in fig. 9, each platen unit 7 further includes a seal 70. The seal 70 may be tape, glue, or other configuration that may be used to join the table 511 to the platen 72. Thereby, the covering portion 722 of the pressing plate 72 is fixed on the table 511, and the airtight effect is further improved.

Referring to fig. 10, 11 and 12, a second embodiment of the present invention is substantially the same as the first embodiment, and also includes the platform 5, the pressing rod unit 6, and the pressing plate unit 7. The difference lies in that:

each platen unit 7 further comprises a first plate 74 and a second plate 75 superimposed on each other along the stacking direction Z. The first plate 74 and the second plate 75 are disposed between the pressing plate 72 and the table 511.

The first plate 74 is disposed on the table 511 of the platform 5 and has a plurality of through holes 741 communicating with the corresponding air holes 512. The second plate member 75 has a second receptacle 751 and a plurality of notches 752 formed at one end. The second insertion hole 751 is sleeved on the insertion part 713 of the sliding member 71. The notch 752 is formed on a side facing the material unit 4 and communicates with the corresponding through hole 741 and the channel 720.

A width W1 of the platen 72 in the axial direction Y is greater than a width W2 of the first plate 74 in the axial direction Y, and a width W2 of the first plate 74 in the axial direction Y is greater than a width W3 of the second plate 75 in the axial direction Y. Therefore, the pressing plate 72 can cover the first plate 74 and the second plate 75, and the notch 752 can expose the through hole 741.

The first plate 74 and the second plate 75 overlapped in the stacking direction Z can support the pressing plate 72, and can prevent the pressing plate 72 from being contracted and deformed to block the air hole 512 when a negative pressure state is formed among the chamber 50, the air hole 512 and the channel 720, thereby maintaining the smoothness of the air flow.

From the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. according to the invention, the channel 720 and the air hole 512 in a negative pressure state can generate adsorption force relative to the bottom surface and the side surface of the material unit 4, so that the material unit 4 is stably adsorbed on the table surface 511, and the material unit 4 is convenient to process. Therefore, the stability of the material unit 4 during processing is improved, and the processing quality and smoothness are improved.

2. And the pressing plate 72 can be matched with the thickness of the material unit 4 to automatically adjust the distance between the pressing plate and the table top 511, and matched with the width of the material unit 4 to adjust the distance between the pressing plate unit 7, so that the material unit 4 with different thicknesses or different widths is suitable, and the convenience and the practicability in use are further improved.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
