Conveyor assembly apparatus

Description

[0001] This invention relates generally to conveyor assemblies and particularly to a conveyor apparatus used in the patterned application of dyestuff or other liquids to carpeting that is in preferably the form of tiles.

[0002] One such conveyor assembly is described in FR-A-2,256,982 (equivalent to US-A-4,034,584 and US-A-4,084,615). The conveyor described has an endless flexible element with first and second longitudinal end portions.

[0003] One major problem with current conveyors used for this application is the inability to align the carpet tiles properly on the conveyor to produce precise repeatable results when being sprayed by electronically controlled gun bars in the form of intricate patterns. One reason for this is the use of dual chains on each side of the conveyor that align and position the carpet tiles on the conveyor. These chains can expand and become misaligned, which causes the slats to be no longer perfectly perpendicular with the longitudinal axis of the conveyor thereby patterning either earlier or later than required for repeatable precise patterned carpet tiles.

[0004] The present invention solves the above problem and others in a manner not disclosed in the known prior art.

Summary of the Invention

[0005] A conveyor apparatus used primarily in processing products such as applying liquids such as dyestuff by means of patterned application of a moving stream of dyestuff, having a first planar portion and an endless flexible element adjacent said first planar portion and a second planar portion adjacent said endless flexible element, where said flexible element has a series of slats mounted thereon that precisely coordinate the processed item underneath the processing element that provides patterned application of dyestuff in order to achieve precise repeatable results.

[0006] Thus in one aspect, the present invention provides a conveyor apparatus (10) for transporting material comprising a first endless flexible element having first and second longitudinal axes;
   characterised by:

(a) a first planar portion (90) having a longitudinal axis adjacent said first endless flexible portion and coplanar therewith;

(b) a second planar portion (90) having a longitudinal axis adjacent said first endless flexible element and coplanar therewith;

(c) wherein said first planar portion (90) and said second planar portion (90) are located on the left and right sides respectively of said first endless flexible element; and

(d) at least one slat (402) removedly attached upon said first endless flexible element for movement therewith and extending across said first planar portion (90) and transverse to the longitudinal axis thereof as well as extending across said second planar portion (90) and transverse to the longitudinal axis thereof, for transporting said material which is supported by said first planar portion (90), said first endless flexible element and said second planar portion (90) and which is in direct contact therewith.

[0007] It is an advantage of this invention to be able to maintain processed material, i.e., carpet tiles, in a fixed location perpendicular to the longitudinal axis of the conveyor for repeatable precise processing.

[0008] It is another advantage to remove processed material by means of lifters and a take-off conveyor so that there is no load placed on the alignment slats.

[0009] These and other advantages will be in part obvious and in part pointed out below.

There are eight "U" shaped support brackets 78 that hold the slat support runners in position. The main conveyor mechanism 10 is stabilized by the upper and lower interconnecting stabilizers denoted by numerals 83 and 82, respectively, which are connected by any attachment means such as hex head cap screws and flat and locking washers located at numeral 101. Each opposing longitudinal end of the conveyor mechanism 10 has an upper and lower pin wheel 72 and 73 respectively. Each pin wheel 72, 73 has seven sides and is mounted on a respective shaft 70, 71 that rotates within a respective pillow block linear bearing 60, 61. Pillow block linear bearing 60 is mounted on a mounting bracket assembly 74, while pillow block linear bearing 61 is mounted directly to the front of conveyor mechanism 10. The upper pin wheel 72 is protected from access by a stand-off load station guard 62. The pin wheels 72, 72 guide and rotate the conveyor plates 86 that travel the longitudinal length through the lateral center of the conveyor mechanism 10.

[0018] Referring now to FIGS. 3, 4 and 15, there are panels 90 on each side of the moving conveyor plates 86. These panels 90 are made from a product manufactured by E. I. du Pont de Nemours & Company of Wilmington, Delaware called CORIAN® that is traditionally used as a material for countertops and can be categorized as a type of plastic. However, a wide variety of materials may be used as a conveyor surface as well as a surface may be used underneath such as 6.4 mm (a quarter of one inch) of aluminum. These panels are attached to the top of the conveyor mechanism 10 by means of bolts 92 or other attachment means. The moving conveyor plates 86 have linear pillow block linear bearings 105, 106 mounted underneath the moving conveyor plates 86 that ride on and enclose cylindrical shafts 103, 104, as shown in FIG. 4.

There are two members 167 and 168 that interconnect and are perpendicular to longitudinal support members 56. There are also three support members 170, 171 and 172 that interconnect members 168 and 159 and a horizontal support beam 360 that interconnects and is perpendicular to lateral support members 167 and 158.

[0024] Referring now to FIGS. 9, 10, and 15, the take-off conveyor is shown generally by numeral 174, as well as in FIGS. 1 and 15, is mounted to the end of the conveyor mechanism 10 by mating L-shaped mounting brackets 502. Tiles are sensed by fiber optic sensor 145, as shown in FIGS. 5 and 10, and then placed on the take-off conveyor 174 by mechanical lifter 110 in conjunction with a triangular tile transfer bar 501, with the lifter 110 being actuated by a cylinder 137 that is fixedly attached to the end of the conveyor by mounting bracket 139. The pin wheels 72, 73 guide the endless loop of conveyor plates 86 with linking pin joints 88 around the conveyor mechanism 10. The take-off conveyor 174 is powered by a pulley 175 driven by a one-fourth horsepower, 3-125 r.p.m., 90 volt DC motor (not shown) that is mounted by angle bracket 518 to the front end of the conveyor mechanism. The pulley 175 drives another pulley 177 by means of a continuous belt 176, as shown in FIGS. 9 and 10. Pulley 177 is connected to drive shaft 178 that traverses the width of the take-off conveyor 174 and is held in position by flange bearings 179 and 180 that are held in position by side plates 181 and 182 respectively. There is a flat face idler 184 that is used to maintain pressure on the belt 176 and is connected to a shaft by means of a tightener (not shown). Toward the center of the side plate 181 as well as side plate 182 is an idler shaft 183 that is rotatable held in position by flange bearings 185 and 186 respectively. Positioned on each side of the idler shaft 183 are positioning rods 187 that extends between side plates 181 and 182 and is connected only by bolts and not bearings. At the end of take-off conveyor 174 is a belt tensioning shaft 188 held in position by bearings 189 and 190 that are also mounted on side plates 181 and 182 respectively. There are eight continuous belts 191 that rotate around the take-off conveyor 174 by means of shafts 178 and 188 while rotating shaft 183. There are eight support ribs 192 positioned longitudinally along the width of the take-off conveyor 174. On both the front and back of the take-off conveyor 174 and from left to right, there are belt spacers 202, 193, 194, 195, 196, 197, 198, 199, 200, and 201. This allows the continuous belts 191 to travel in predefined paths.

[0025] Referring now to FIGS. 1, 11, 12, 13, and 14, the conveyor mechanism 10 can be adjusted to process various heights of carpet tile by moving the conveyor mechanism support system 11 to numerous fixed points underneath the slanting gun bar assemblies 44 by means of a locking assembly generally indicated as numeral 461.
