Description

DESCRIPTION

LASER MACHINE WITH FOUR SLIDING TABLES AND METHOD OF LOADING

PRODUCT

Making patterns and marking with laser beam over confection or similar products with four independently working tabled machine and the method of marking,

This invention is about, making patterns and marking with laser beam over confection or similar products with four independently working tabled machine and the method of marking.

In some conventional laser machines, the table where the products to be marked are placed is a fixed table. It does not move. Operator locates the product over the table and marks it. After that operator takes it back and locate the new product. The¹ machines which are using this fixed table method have very low efficiency in production. During operator is locating the product, laser marking is stopped and waits for the operator. On the other hand, the operator's health is under risk since he is working over the laser active zone.

In other conventional laser machines, table is moving to right and left. These machines have three zones. Right and left zone are the product locating zones. The middle zone is the laser marking zone. These machines' efficiency is higher than the fixed tabled machines but the size of the machine is big. The operator has to walk to the right or to the left every time to locate the products. This makes operator to get tired.

In other conventional laser machines, the table is designed like a moving band conveyor. The products are located over the band and the products to be marked are moved over this conveyor system. In these systems, the conveyor band moves very slowly so the efficiency is low. Additionally after marking process, the products folding shape is changed. If the product will be marked again, the operator has to fold the product again. In these systems, at least two operators have to operate the machine. These causes additional labor and time loss.

In other conventional laser machines, there are two sliding tables. These tables are located vertical or horizontal. Whe one table is in marking zone, the other table is in loading zone. When the tables start moving to change their locations, the laser marking stops and time loss occurs.

In all conventional laser machines, the laser tube(s) is/are located outside area of the machines. These causes to increase the size of the machines. So the machines will cover big area in the factories and it is a big disadvantage for the factories.

In the new invention, the laser machine has four independently working tables. These four tables are located vertically and horizontally. Two of them slide in the top rail, two of them slide in the bottom rail. At least one table is in marking zone every time. Laser marking never stops. Two operators can also work together with the new invention.

In the new invention, the laser tube(s) is/are located inside the marking zone. This design makes the machine more compact in dimensions. The machine covers less place than other laser machines in the factories.

In the new invention, the operator health and safety is also protected every time.

To finalize the invention, the machine is designed like attached figures. These are;

This machine consists of marking zone, laser source (3), mirrors which are directing the laser beam (33, 34), power box which is used to change the laser beam diameter (32) and the table which is used to locate the products on to be marked (35). This machine's marking zone is not bigger than the marking area (20). When the laser beam comes out from the laser source (3) first it turns right 90° with the mirror (33) and then it turns again 90° with another mirror (34) and get inside the power box (31). 3^rd axis(2) and two axis laser pointer (32) are located near the laser source. So efficient design is done to save from the space. In conventional laser machines, these components are located in linear position. This makes the a long marking unit design. By using mirrors (33, 34) the new machine's marking unit length is shortened and fit inside the marking area. In this new marking system, 3^rd axis scanner (2) is located in the middle of the marking zone (20). All components of the marking unit (3, 33, 34, 31, 2, 32) are fixed to laser source connection table (35). Linear movement mechanisms (25) have sufficient bearings (27) to move easily. Linear movement mechanisms are moving up and down over the rail by the help of bearings (27). This movement is done by servo motor (28) and the screwed shaft (29). When servo motor turns (28), it turns the trigger belt (30). Trigger belt moves the screwed shaft (29). The linear movement mechanisms are moved over the rails up and down because they are connected to the screwed shaft. With this method, the marking unit is moved over marking zone (20) up and down. The operator can easily set the height of the marking process. The all electronical parts of the laser machine are located inside the electronical cabinet (24). With the help of additional placed two axis laser pointer (32), if the operator does not want to use the moving tables (4, 5, 36, 37), he can send them to the marking zone (20) and use the machine like a fixed table laser machine. Two axis pointer (32) helps operator where to locate the new products over the tables (4, 36) during laser marking the other products.

In this new laser machine, the loading unit consists of FOUR sliding tables (4, 5, 36, 37), helis gear rails (9, 17, 38, 39), rail systems (8), movement arms (12), movement arm connection shafts (19), bottom table chassis (11), servo motors (16, 18, 10, 40, 41, 42) and the gears (14, 15).

In this new machine system, top tables (4, 36) move over the rail (6) by the help of linear movement mechanisms (8). The top tables (4, 36) move from marking zone (20) to locating zone (21) with the help of servo motors (10, 40). Over the locating zone (21) two axis laser pointer (1) is located. This pointer (1) shows where the new products will be located. Operator locates the product over the table (4, 36) and sends it to the marking zone (20). When it reaches the marking zone (20), marking process starts. The top tables (4, 36) move from the locating zone to the marking zone, the bottom tables (5, 37) move from the marking zone to the locating zone. One operator loads products to left side (4, 5) tables of the laser machine. The other operator loads products to right side (36, 37) tables of the laser machine. So laser machine works continuously without any stopage of laser marking with two operators. In this four tabled (4, 5, 36, 37) system, one or two tables are always in the marking zone. When the laser is marking products over left top table (4), the operator loads products over right top table (36) and sends it to marking zone. When the laser marking finishes over the left top table (4), marking starts over right top table (36). The finished products over the left top table (4) moves to loading zone and the operator loads new products to this table. When the laser marking finishes over the right top table (36), marking starts over left bottom table (5). When the laser marking finishes over the left bottom table (5), marking starts over right bottom table (37). This process goes on in this order without loss of time in laser marking and loading product timing. The laser marking never stops.

The bottom tables (5, 37) and the top tables (4, 36) are continously moves between marking zone (20) and loading zone (21). All four tables (4, 5, 36, 37) are always coming in front of the operator. The operator does not have to walk to load the new products.

The top tables (4, 36) and the bottom tables (5, 37) do not move in the same level. The bottom tables (5, 37) are below the marking level (22) and locating zone (23). This is a big problem for the perfect marking process. During laser marking, 3 axis laser must have the same distance to moving tables (4, 5, 36, 37). But these four moving tables (4, 5, 36, 37) are not moving in the same level. Otherwise there will be marking power differences between the products. In the new laser machine, this level (22, 23) problem is solved by moving up and down the bottom tables (5, 37). This movement is also needed when there is products over the bottom table. Those products may touch the top table and their locations can be changed. The movement arms (12) connected to bottom table and bottom table chassis (11). The arms are connected through bottom table movement arms' power transfer shaft (13). These arms tranfer the movement with the help of servo motor (16, 42) and the gears (14, 15).. The bottom tables (5, 27) moves to up from the marking zone (Figure 5 & 9) and the bottom table reaches to the marking level (22). In this point, both top (4, 36) and bottom (5, 37) tables are in the same level (22, 23). When the bottom tables (5, 37) move to the locating zone, first the arms (12) lifts down the bottom table (5, 37). When the bottom table (5, 37) is in the bottom level, they move to the locating zone with the help of bottom table chassis (11), linear movement mechanisms(8) and linear rails (7). This movement is done by servo motors (18, 41). Servo motors (18, 41) move them over helis gear rail (17, 38). When bottom tables move to locating zone (21), the top tables (4, 36) move with the help of servo motor (10, 40) by going over rails (6) to the marking zone. When the bottom tables reach to the locating zone, the movement arms lifts us the bottom tables (5, 37) to the marking level. In this position both bottom table (5, 37) and the top tables (4, 36) are in the same level. So the operator can easily locate products. All four tables (4, 5, 36, 37) can move independantly.
