Description

DESCRIPTION INNOVATION IN PALLET MECHANISM OF ARM SEWING MACHINE TECHNICAL FIELD The invention relates to an innovation in the pallet mechanism of the lever sewing machine.

KNOWN STATE OF THE TECHNIQUE Known technique in arm sewing machines in the state of the art In the pallet mechanism, there are two front rollers and rear rollers. There is a reel. The front roller and rear roller are movable rollers. your technique Piston connecting fork in its known state contact of the tip of the front roller to the pallet belt linearly lets him do it. Then, on the piston connection fork in the state of the art. With the increase in the pressure force, the front roller starts to press the pallet belt. the rear roller can be lifted up. Lifting the rear roller up in the case of the fabric being sewn, since the forces acting on the pallet belt change. the stitch name changes. This is absolutely undesirable by customers.

The operation of the rear roller as it rises and falls upwards to the pallet belt. Due to the variable incoming force, it causes a shorter lifespan.

DESCRIPTION OF THE INVENTION The invention solves the problems described above.

In the pallet mechanism of the arm sewing machine developed in the invention, the front roller on the upper side of the rear roller, which is located on the rear There is an upper roller positioned. pallet with top roller rear roller when the rear pulley operates, because it is positioned between the belt It certainly cannot go up. This ensures that the sewn fabric is not damaged. and ensures that the sewing steps on the fabric are not disturbed.

DESCRIPTION OF THE INVENTION Known technique found in arm sewing machines (1) in the state of the art the piston in the state of the art in the pallet mechanism (10) in the state of the art the connecting yoke (1.2) is attached to the end leg (1.10) also behind the rear roller (1.5) L Male external piston at the junction point of the other part forming a geometry close to with pressure rod screw (1.16) and female outer piston pressure rod screw (1.17) is fixed. The end leg of the piston connecting fork (1.2) in the state of the art In case of positioning this way on the part (1.10), the pressure piston (1.3), pressure by means of the pressure piston rod (1.3.1) moved downwards When applying, first the end part of the front roller (1.4) is linearly attached to the track belt. is in contact. Then the pallet of the front roller (1.4) and the rear roller (1.5) The compression force of the compression piston is increased in order to press the belt (1.18).

With excessive pressure force, the front roller (1.4) and the rear roller (1.5) are attached to the track belt. (1.18) pressure causes the life of the pallet belt (1.18) to be shortened. cause damage to the fabric sewn next to it and the seams on the fabric. is happening.

Known technique found in arm sewing machines (1) in the state of the art front roller (1.4) and rear roller (1.5) in the track mechanism (10) are available. The front roller (1.4) and the rear roller (1.5) are movable rollers.

In the state of the art, the piston connection fork (1.2) is connected to the compression piston rod (1.3.1). with the downward movement of the end of the front roller (1.4) linearly it makes contact with the apricot (1.18). Then in the state of the art The front roller (1.4) pallet with the increase of the pressure force on the piston connection fork (1.2) starts to press the belt (1.18) while the rear roller (1.5) moves up. can get up. In case the rear roller (1.5) lifts up, the pallet because the forces on the apricot (1.18) change, the stitch step in the fabric being sewn changes. This is absolutely undesirable by customers. Back the operation of the roller (1.4) as it rises and falls upwards to the pallet belt. (1.18) due to the variable incoming force causes a shorter life span. is happening.

In the pallet mechanism (20); - the mounting axis of the front roller (1.4) and the rear part of the end leg (1.10) mounting axis in the middle of the reel (1.5) mounting axis as will be - L with the descending part of the end leg (1.10) from top to bottom so that it will be above the other part, which creates a geometry close to There is a piston connection fork (1.1) positioned.

In the pallet mechanism (20) of the arm sewing machine (1) developed in the invention, the end foot (1.10) of the mounting axis of the front roller (1.4) and the rear roller (1.5) With the mounting axis in the middle of the mounting axis and the end leg (1.10) forming a geometry close to L with the part descending from the top to the bottom. that the piston connection fork (1 .1) is installed so that it is above the other part It reduced the force on the pallet belt (1.18). say; pressure piston of the front pulley (1.4) and the rear pulley when the spindle (1.3.1) moves down. (1.5) provides superficial contact with the pallet belt (1.18). Front roller (1.4) and rear roller (1.5) superficially press on track belt (1.18) When it is done, it ensures the pulling of the fabric that is sewn with less force. pallet to apricot (1.18) less force will result in a longer life of the pallet belt (1.18). damage to the fabric being sewn and the seams on the fabric being sewn. makes it impossible to see.

In the pallet mechanism (20) of the arm sewing machine (1) developed in the invention, the front top of the rear pulley (1.5), which is positioned on the back of the pulley (1.4) There is an upper roller (1.6) positioned on the side. Upper roller (1.6) Since it is positioned between the rear roller (1.5) and the track belt (1.18), the rear The pulley (1.5) cannot lift up when the front pulley (1.4) is running. This condition to ensure that the fabric being sewn is not damaged and that the sewing steps on the fabric makes sure it doesn't break.

Piston connecting fork (1.1) developed in the invention, - left pallet pressure fork arm (1.1.1), - right pallet pressure fork arm (1.1.2) - left pallet press fork arm (1.1.1) and right pallet press fork arm (1.1.2) from the connecting yoke joint (1.1.3) is formed.

The piston connecting yoke (1.1) developed in the invention is on the fork connecting rod (1.1.3) with the male thread on the piston rod (1.3.1). is stuck. Front roller (1.4), rear roller (1.5) and Upper roller (1.6) are movable rollers and they act as pulling the sewn fabric.

The pallet of the arm sewing machine (1) developed in the invention in Figure-8 The assembly of the parts of the mechanism (20) is done as follows: A wheel ring (1 .14) is attached to the front roller (1.4).

A wheel ring (1.14) is attached to the rear roller (1.5). A wheel ring (1.14) is attached to the upper roller (1.6).

One wheel ring on pallet end left cover (1.12) and pallet end right cover (1.13) A wheel ring (1.14) is mounted on the front pulley (1.4) fitted (1.14). of the rear pulley (1 .5) and the upper pulley fitted with a wheel ring (1 .14). (1.6) is fixed on both sides with three screws-2 (1.11).

The bearing (1.8) is placed on the end leg (1.10).

The ring (1.9) is attached to the bearing (1.8).

The bearing (1.8) with the ring (1.9) fitted is attached to the left pallet pressure fork arm (1.1.1).

The left pallet pressure fork arm (1 .1.1) obtained in this way, the pallet with the help of screw-1 (1 .7) the end is inserted into the slot on the left cover (1.12).

Other bearing (1.8) fitted with other ring (1.9) to right pallet pressure fork arm (1.1.2) is stuck.

Right pallet pressure fork arm (1.1.2) obtained in this way, via other screw-1 (1.7) with the pallet end is attached to the slot on the right cover (1.13).

Left pallet presser fork arm (1.1.1) is attached to the fork bracket via screw-3 (1.15) (1.1.3) is fixed.

Right pallet pressure fork arm (1.1.2) fork connection via other screw-3 (1.15) log (1.1.3) is fixed.

On the left pallet pressure fork arm (1.1.1) and the right pallet pressure fork arm (1.1.2) female-to-female thrust on the positioned yoke joint (1.1.3) Fork joint stem by screwing the male thread on the piston rod (1.3.1) (1.1.3) is located on the pressure piston (1.3).
