The feeding device 11 includes anendless conveying belt 111, anair suction device 112 disposed below theendless conveying belt 111 to generate a suction force in a downward direction (B), and ablocking piece 113 disposed at a level above theendless conveying belt 111. The blockingpiece 113 has a bottom side which cooperates with theendless conveying belt 111 to confine a slit (C) for passage of thepaper material 2 therethrough. Theconveying device 12 includes twocylindrical rollers 121 that are vertically spaced apart from each other. The distance (D) between therollers 121 is slightly smaller than the width of the slit (C). - In use, a stack of the
paper material 2 is loaded on theendless conveying belt 111 of the feeding device 11. Theair suction device 112 generates a suction force in the downward direction (B), so as to enable the bottommost sheet of thepaper material 2 to stick onto theendless conveying belt 111 since the width of thepaper material 2 is larger than the width of theendless conveying belt 111. Theendless conveying belt 111 is operable to convey the bottommost sheet of thepaper material 2 along the conveying direction (A) through the slit (C) toward theconveying device 12 while the remaining sheets of thepaper material 2 on theendless conveying belt 111 are blocked by the blockingpiece 113. - The
rollers 121 rotate in opposite directions to guide the sheet of thepaper material 2, which passes through the slit (C), to enter therebetween. Since the thickness of each sheet of thepaper material 2 is slightly larger than the distance (D), the tworollers 121 may respectively press against the top and bottom surfaces of the sheet of thepaper material 2 upon entrance, and in the meantime generate a friction force to the top and bottom surfaces of the sheet of thepaper material 2, so that the sheet of thepaper material 2 can be conveyed along the conveying direction (A) and to a follow-up processing station. - However, when the conventional conveying apparatus 1 is used to convey the
paper material 2 having a larger thickness and exhibiting shock-absorbing capability, such as paperboards, cardboards, corrugated boards, etc., the aforementioned pressing by therollers 121 may cause damage to the structure of thepaper material 2, thereby affecting the shock-absorbing capability of thepaper material 2. - Therefore, an object of the present invention is to provide a conveying apparatus for conveying paper material that can overcome the aforesaid drawback of the prior art.
- According to the present invention, a conveying apparatus for conveying paper material includes a feeding device, a belt-type conveying device, and an air suction device. The feeding device is for loading the paper material thereon, and for conveying the paper material along a conveying direction. The belt-type conveying device is disposed adjacent to the feeding device for receiving the paper material conveyed by the feeding device and for conveying the paper material along a conveying path. The belt-type conveying device has a supporting side to support the paper material and is formed with air vents through the supporting side.

- Referring to
FIGS. 2 to 4 , the first embodiment of a conveying apparatus according to the present invention is shown for conveyingpaper material 3 along a conveying direction (E). The conveying apparatus includes afeeding device 5, a belt-type conveying device 6, anair suction device 7, and ahousing 4 that houses thefeeding device 5, the belt-type conveying device 6, and theair suction device 7 therein. - The
feeding device 5 is loaded with a stack of thepaper material 3 thereon and is operable to convey thepaper material 3 along the conveying direction (E). Thefeeding device 5 includes anendless conveying belt 51, and ablocking piece 52 that is disposed at a level above theendless conveying belt 51, and that has a bottom side which cooperates with theendless conveying belt 51 to confine a slit (F) for passage of a sheet of thepaper material 3 therethrough. - The belt-
type conveying device 6 is disposed adjacent to thefeeding device 5, and is operable to receive thepaper material 3 conveyed by thefeeding device 5 and to convey thepaper material 3 along a conveying path. The belt-type conveying device 6 has a supporting side to support thepaper material 3 and is formed withair vents 611 through the supporting side. The belt-type conveying device 6 is configured so as not to press a top surface of thepaper material 3 conveyed thereby. - As shown in
FIGS. 3 and4 , the belt-type conveying device 6 of this embodiment includes a plurality ofendless conveying belts 61, a plurality ofslide units 62, and a plurality ofrails 63. Theendless conveying belts 61 extend in the conveying direction (E), are disposed side by side with respect to each other, and are spaced apart from one another in a transverse direction (G) that is transverse to the conveying direction (E). Therails 63 are spaced apart from one another and extend along the conveying direction (E). In this embodiment, theendless conveying belts 61 cooperatively form the supporting side of the belt-type conveying device 6, and each of theair vents 611 is defined by two adjacent ones of theendless conveying belts 61 and by two adjacent ones of therails 63 corresponding in position to the two adjacent ones of theendless conveying belts 61. Each of theslide units 62 is disposed in a respective one of theair vents 611 and has a plurality ofrolling members 621 that are mounted rollingly in the respective one of theair vents 611. Adjacent ones of therolling members 621 in each of theslide units 62 are spaced apart from each other in the conveying direction (E), and cooperatively form a plurality ofspacings 622 therebetween. Therolling members 621 respectively have top edges that are disposed lower than top surfaces of theconveying belts 61. - In this embodiment, each of the
rolling members 621 is a rolling pin having a central axis extending along the transverse direction (G), and two opposite ends mounted rotatably and respectively to two corresponding ones of therails 63. - As shown in
Figure 2 , in this embodiment, theair suction device 7 is disposed below both thefeeding device 5 and the belt-type conveying device 6, and is operable to generate a suction force substantially along a downward direction (H). - The
air suction device 7 includes anair suction unit 71 disposed below both thefeeding device 5 and the belt-type conveying device 6 for generating the suction force that enables thepaper material 3 to stick to both thefeeding device 5 and the belt-type conveying device 6. - The
air suction unit 71 has acasing 711 surrounding both thefeeding device 5 and the belt-type conveying device 6 , and a negativeair pressure generator 712 which is connected to thecasing 711 and which is operable to generate the suction force by creating negative air pressure in thecasing 711. Since the structure of the negativeair pressure generator 712 is not a feature of the present invention, and the mechanism of the negativeair pressure generator 712 is conventional, such as by using a vacuum pump, further details of the same are omitted herein for the sake of brevity. - When in operation, the
conveying belt 51 of thefeeding device 5 is loaded with thepaper material 3. The suction force generated by the negativeair pressure generator 712 of theair suction unit 71 along the downward direction (H) enables the bottommost sheet of thepaper material 3 to stick to theconveying belt 51 since the width of thepaper material 3 is larger than the width of the endless conveying belt 51 (not shown). Theconveying belt 51 of thefeeding device 5 then conveys the bottommost sheet of thepaper material 3 along the conveying direction (E) toward theconveying device 6 through the slit (F). In the meanwhile, the remaining sheets of thepaper material 3 loaded on thefeeding device 5 are blocked by theblocking piece 52 and stay on theconveying belt 51 of thefeeding device 5. Thereafter, as shown inFIGS. 2 and3 , the bottommost sheet of thepaper material 3 conveyed by thefeeding device 5 is further conveyed onto theendless conveying belts 61 of the belt-type conveying device 6. The suction force generated by theair suction unit 71 of theair suction device 7 enables the sheet of thepaper material 3 conveyed by thefeeding device 5 to stick to theendless conveying belts 61 via thespacings 622 formed among therolling members 621. Afterwards, the sheet of thepaper material 3 is conveyed outwardly of thehousing 4 by theconveying belts 61 to complete the conveying process. - It is worth noting that since the negative air pressure generated by the negative
air pressure generator 712 of theair suction unit 71 enables the sheet of thepaper material 3 to stick to theendless conveying belts 61 via thespacings 622 formed among therolling members 621, and since the top edges of therolling members 621 are disposed lower than the top surfaces of theendless conveying belts 61, the sheet of thepaper material 3 conveyed onto theendless conveying belts 61 is usually not in contact with therolling members 621. However, when the suction force generated by theair suction device 7 is too large, the sheet of thepaper material 3 on theconveying belts 61 may deform to contact therolling members 621, but in a rolling-contact manner such that thepaper material 3 can be prevented from sticking too tightly onto theendless conveying belts 61 and may still be conveyed along the conveying direction (E) . In addition, thepaper material 3 is less susceptible to permanent deformation owing to this rolling-contact manner with therolling members 621. - Referring to
FIG. 5 , the second embodiment of the conveying apparatus according to the present invention is shown to be similar to that of the first embodiment. The difference between the first and second embodiments resides in that theair suction device 7 of the second embodiment includes a firstair suction unit 72 disposed below thefeeding device 5, and a secondair suction unit 73 disposed below the belt-type conveying device 6. - The first
air suction unit 72 has acasing 721 surrounding thefeeding device 5, and a negativeair pressure generator 722 connected to thecasing 721. The secondair suction unit 73 has acasing 731 surrounding the belt-type conveying device 6, and a negativeair pressure generator 732 connected to thecasing 731. - Each of the negative
air pressure generators casings paper material 3 to stick to a respective one of thefeeding device 5 and the belt-type conveying device 6. This configuration allows the negative air pressure in thecasings feeding device 5 and the belt-type conveying device 6 can be therefore adjusted according to different demands and result in a relatively wide range of applications. - As shown in
FIG. 2 and further referring toFIG. 6 , it is worth noting that in other embodiments, thefeeding device 5 may be configured similarly as the belt-type conveying device 6 of the first embodiment to further include a plurality of the endless conveying belts 51 (seeFIG. 6 ), a plurality ofslide units 53, and a plurality of rails (not shown). As shown inFIG. 6 , theendless conveying belts 51 extend in the conveying direction (E), are disposed side by side with respect to each other, and are spaced apart from one another in the transverse direction (G). Theendless conveying belts 51 cooperatively form a supporting side of thefeeding device 5. Thefeeding device 5 is formed withair vents 511 through the supporting side, and each of theair vents 511 is defined by two adjacent ones of theendless conveying belts 51 and by two adjacent ones of the rails corresponding in position to the two adjacent ones of theendless conveying belts 51. Each of theslide units 53 is disposed in a respective one of theair vents 511 and has a plurality of rollingmembers 531 that are mounted rollingly in the respective one of the air vents 511. Adjacent ones of the rollingmembers 531 in each of theslide units 53 are spaced apart from each other in the conveying direction (E), and cooperatively form a plurality ofspacings 532 therebetween. The rollingmembers 531 respectively have top edges that are disposed lower than top surfaces of the conveyingbelts 51. - To sum up, the suction force generated by the
air suction device 7 enables the sheet of thepaper material 3 to stick to the endless conveyingbelts 61 via thespacings 622 upon conveyance on the belt-type conveying device 6, so that the drawback of deformation of thepaper material 3 due to pressing upon conveyance by using the aforementioned conventional conveying apparatus can be avoided. Moreover, the rollingmembers 621 can prevent damage to the surface of thepaper material 3 when the suction force is too large while thepaper material 3 is being conveyed by the conveyingbelts 61.
