Description

A WHEELED DRIVE MECHANISM PROVIDING MOTION OF FABRIC SPREADING

MACHINE

Technical Field

The present disclosure is related to the fabric spreading machines used for laying fabric in cutting department in the sewn-goods sector.

The present disclosure is particularly related to the drive mechanism which enables the fabric spreading machine to move in a horizontal manner on the table and takes its power directly from the motor.

State of the Art

Today, fabric spreading and cutting machines are used to cut the fabrics in the sewn-goods field in a proper manner automatically. The fabric spreading machines act for laying the fabrics in layers and in the same alignment by means of moving forward and backward on long tables called marker tables. For this process rolls of fabric are placed in the fabric spreading machines. Subsequently the fabric spreading machine moves forward and backward on the table in a horizontal manner and during this motion, it lays the fabric within itself on the table.

A drive mechanism is used for said horizontal motion of the fabric spreading machines.

The horizontal motion of the spreading machine on the cutting table in the prior art, is enabled by means of transferring the drive received from the motor by timing belt or chain gear mechanism. These systems fail frequently during operation and affect the productivity in a negative manner by decreasing the operating period. The service expense after failure is also among the disadvantages.

The transfer mechanism used in the prior art consists of the parts as the roller bearing, the motion transfer shaft, the timing belt, the timing gear, the belt-tension apparatus. Thus, this will increase the material cost used for the assembly and also the production costs.

In the prior art, as it is mentioned in the above paragraph, because the transfer mechanism consists of many elements, the period of assembly extends. Thus this will cause more labor for assembly and disassembly. In the prior art, each said transfer mechanism element causes loss in productivity due to frictions and flexion. The energy which is lost due to friction is gained by using a more powerful motor. This will also result in using more energy consumption.

In the patent research made according to the prior art the file No US3922765A is found. In this application a chain gear system is used for laying the fabric on the table. In the invention, using gear systems in the drive mechanism increases the labor and number of failures during assembly-disassembly processes.

As a result; the fabric spreading machines are developed parallel to the developing technology, for this reason new configurations are required in order to eliminate above mentioned disadvantages and bring solutions to the current systems.

Aim of the Invention

The invention is related to the fabric spreading machines that are different from the embodiments within the prior art, that are developed for solving said disadvantages and that bring some additional advantages.

The aim of the invention is to eliminate the mechanism elements used in the prior art such as the roller bearing, timing belt, timing gear, belt-tension apparatus by means of the developed wheeled system for moving the machine. Therefore the production cost decreases.

Another aim of the invention is to decrease the number of failures of the drive mechanism which is assembled by means of a simple assembly and less number of parts. Therefore the production loss due to downtime are decreased. Also it is not required to continuously call for service.

Another aim of the invention is to facilitate assembly and disassembly processes by means of a simple structured drive mechanism. Therefore labor processes will be decreased.

Another aim of the invention is to eliminate power losses occurred due to friction and flexion by means of taking the drive directly from the motor.

Another aim of the invention is to save energy in the business by means of eliminating power losses.

In order to fulfill the above mentioned aims; a motion mechanism is developed that has a drive element, which is fixed to the machine side body, and that moves the fabric spreading machine, which lays the fabric by forward and backward motion horizontally on the marker table in the sewn-goods sector. The motion of said fabric spreading machine in a horizontal manner by sliding is enabled by means of the motion wheel. Said motion wheel is engaged to drive element with the wheel drive shaft. It comprises a reducer which is attached to said drive element and transfers the motion coming from drive element to the motion wheel directly by means of the wheel drive shaft.

The structural and characteristic features of the present invention will be understood clearly by figures and detailed description which is written by referring figures therefore the evaluation shall be made by taking the detailed description into consideration.

Detailed Description of One Example of the Invention

Structure principle; Said drive mechanism (1 10) consists of the drive element (1 1 1 ), the reducer (1 12), the motion wheel (1 13), the wheel drive shaft (1 14), and the motion support roller bearing (1 15). Figure 2 and 3 shows perspective views of the drive mechanism (1 10).

As the drive element (1 1 1 ), two motors are used. 0,37 kW powered motor is used in the invention, but this can vary according to the size of the machine. The drive elements (1 1 1 ) which are moved in a coordinated manner by the control system of the fabric spreading machine (100) moves the fabric spreading machine (100) in a steady manner.

The reducer (1 12) was used only as a cycle reducer in the prior art. The reducer (1 12) used in the invention functions also as a wheel housing.

The motion wheel (1 13) is the element which enables the fabric spreading machine (100) to move forward and backward on the table (200).

The wheel drive shaft (1 14) is the element which receives the forward and backward functional motion of the fabric spreading machine (100) directly from the drive element (1 1 1 ) and at the same time acts as a wheel shaft.

The motion support roller bearing (1 15) is the element which supports the fabric spreading machine (100) for not imposing its whole weight on the reducer (1 12).

Said drive mechanism (1 10) is engaged with the machine side body (101 ). The machine side body (101 ) is the plates that carry all parts of the drive mechanism (1 10). The sheet thickness was 5 mm in the prior art but it is decreased to 3 mm with this invention.

Assembly principle:

Figure 1 is a perspective view of the fabric spreading machine (100) on which the invented drive mechanism (1 10) is applied. As it can be seen in the figure, the fabric spreading machine (100) is positioned on the marker table (200) on which the fabrics to be cut will be laid and cut. The fabric spreading machine (100) acts for laying said fabrics. For this process it makes horizontal forward and backward motion in X and Y directions on the table (200).

The drive mechanism (1 10), which is the subject matter of the invention is mounted on the opposite side bodies (101 ) of the fabric spreading machine (100) for said forward backward motion.

Initially, the drive element (1 1 1 ) is fixed to the machine side body (101 ). The reducer (1 12) is engaged to the drive element shaft (1 1 1 1 ) located on the end portion of the drive element (1 1 1 ). The wheel drive shaft (1 14) is fitted in a vertical manner to the drive element shaft (1 1 1 1 ) in the middle section of the reducer (1 12). The wheel drive shaft (1 14) passthrough the opened hole on the machine side body (101 ) and is engaged with the motion wheel (1 13). Before this engagement, the motion support roller bearing (1 15) is positioned between the reducer (1 12) and the machine side body (101 ) so that imposing all weight of the fabric spreading machine (100) onto the reducer (1 12) is prevented.

This assembly system is made on both of the opposite side bodies (101 ) of the fabric spreading machine (100). As a result, two drive mechanisms (1 10) are assembled.

As it is described, the detailed views of the assembled drive mechanism (1 10) on the machine side body (101 ) are seen in Figure 2 and 3.

Operation principle;

The fabric spreading machine (100), which holds the subject matter of the invention; is the automatic fabric spreading machine which is used in the cutting department in sewn-goods sector. The fabric spreading machine (100) lays the fabric on a purpose-built table (200) with a desired tension. During this laying process the drive mechanism (1 10) whose assembly is described above moves the fabric spreading machine (100) in X and Y directions horizontally.

The motion wheels (1 13) are seated on the wheel rail (210) attached to the sides of the marker table (200) after assembly. The said motion in X and Y directions is performed by sliding of the motion wheels (1 13) on this wheel rail (210).
