Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a method of controlling a side bonding apparatus of a vinyl wrapping machine,

The present invention relates to a method of controlling a side joining apparatus of a textile vinyl wrapping machine, and more particularly, to a method of controlling a side joining apparatus that ensures reliable lateral joining regardless of the diameter of a fabric to be wrapped.

In general, the fabric means a fabric that can be cut immediately after being left the textile factory and subjected to a dyeing process and a special processing process (if necessary), or a product rolled up in a rolled shape.

The roll-type fabric that has been subjected to the dyeing process and the like is finally subjected to a vinyl wrapping process before shipment. The outline of the wrapping operation will be described with reference to FIG. 1, which is a plan view of the vinyl wrapping machine.

(Hereinafter referred to as "fabric") W entered into the fabric vinyl packing machine 10 along the horizontal conveyor line L is placed on a fabric reception table 11 on which a vertical wide- The lower end of the vinyl film V is wrapped around the fabric W by the action of the pneumatic cylinder C located on the backside of the vinyl film V as the fabric W is rolled forward.

Next, a thermal bonding apparatus (not shown) provided at the distal end of the far-end reception table 11 is operated to perform high-frequency thermal bonding across the left and right ends of the vinyl film surrounding the fabric, and a cutting edge (not shown) Cut the end of the region.

On the other hand, two kinds of sensors (not shown) are mounted at a point just before the cloth W is lifted out of the horizontal conveyor line L and placed on the far-end reception desk 11, That is, the width (length) and the diameter (thickness), respectively, and transmits them to the control unit 16.

In other words, each time the packed fabric enters the far-end reception desk 11, each far-end characteristic is input to the computer device in the controller 16. [

As the pneumatic cylinder (not shown) below the far-end reception table 11 is operated simultaneously with the cutting of the end portion of the joint portion, the fabric W is wound on the vinyl film removing stand 12 having a V- .

At the moment of release, as shown in the drawing, the extra vinyl film is horizontally connected to the left and right ends of the fabric surrounded by the long vinyl film cylinder V '. (a: extra vinyl film portion)

Subsequently, a separate thermal bonding apparatus, that is, a side joining apparatus 13 disposed on both sides of the left and right sides of the vinyl film removing stand 12 is advanced to both left and right ends of the fabric (see arrow) to grasp the extra vinyl film portion (a) (Not shown) cuts and removes the outer side of the bonded portion, the operation of wrapping the fabric vinyl wrapping operation, that is, the wrapping of the fabric into plastic is substantially completed. (E: end of vinyl film after cutting and removal)

The operation start of the side joining device 13 is based on the output signal from the control unit 16, that is, the device driving signal, with respect to the input signal from the sensor that senses the entrance of the fabric on the vinyl film removing stand 12.

The sensor for detecting the entrance of the fabric is a weight sensor located under the vinyl film removing table 12, but it is not necessary to understand the position or shape of the sensor.

The waste vinyl collecting box 14 is constituted by a take-out stand 15 composed of a take-out roller 15-1 and a take-out guide plate 15-2, a corrugated pipe 17, a closed suction motor 18 But there is no direct connection with the contents of the present invention, and a detailed description thereof will be omitted.

The side joining apparatuses 13 on the left and right sides of the vinyl film removing stand 12 are structured so as to be able to move along the width of the fabric, that is, the length thereof. In other words, when the fabric width is wide, When the width is narrow, the space is narrowed.

The side joining principle will be briefly described. A heat generating cartridge H (i.e., a heating element) provided in a horizontally movable structure, that is, a heating element is moved in the direction in which the right and left ends of the side joining apparatuses 13 face each other ) As the mutual contact state is maintained for a predetermined time, the portions of the vinyl film between them are pressed and bonded.

Horizontal movement of the left and right heat generating cartridges H is performed by a double acting type air cylinder (hereinafter referred to as a " cartridge cylinder ") as a cartridge driving cylinder to which the mutual contact and separation of the left and right heat generating cartridges H are performed, Operation of the timer device for circuit switching.

The operation of the timer device, that is, the cartridge cylinder timer device is also performed in accordance with a control signal from the computer device in the control unit 16, and the position of the cartridge cylinder timer device may be other than inside the side joining device 13 .

However, as shown in FIG. 2, in the case of the side joining apparatus according to the conventional structure, side joining defects often occur when the diameter of the raw fabric is considerably large or small.

Reference numeral 'W1' designates a large diameter fabric, and 'V1' designates a vinyl film portion to be removed after side bonding in a large diameter fabric, and the vinyl film portion between the two arrows in the drawing is a region to be thermally bonded. (&Quot; W2 ", " V2 " indicates a case of a small diameter fabric)

Specifically, in the case where the diameter of the packaging target fabric is large and the amount of the vinyl film to be thermally bonded is large (in case of Fig. 2 (a)), since the heat bonding at the part is weak due to the insufficient amount of heat at the heat generating cartridge part, In the case where the diameter of the packaging target fabric is small and the amount of the vinyl film to be thermally bonded is small (in case of FIG. 2 (b)), the amount of heat in the heating cartridge portion is excessive, It also causes damage to the fabric as well as burning.

In either of these cases of heat deficit or overheating, work delay or fabric damage at the time of side joining failure usually leads to a significant level of economic loss.

According to the conventional method of controlling the side joining device, although the mutual contact holding time (hereinafter, referred to as 'cartridge contact time') of the left and right heat generating cartridges is uniformly applied to the medium size of the medium diameter in approximately 6 seconds, It has been impossible to surely carry out side-bonding processing for various fabrics having a large diameter and a small diameter.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a side joining device control method capable of surely performing side joining processing on various fabrics of large and small diameters irrespective of the diameter of a fabric to be wrapped .

The above-described object of the present invention is achieved by controlling the side joining device of the fabric vinyl wrapping machine by changing the contact time of the cartridge according to the diameter of the packaging target fabric.

Specifically, according to the method of controlling a side joining device of the present invention, the side joining is not progressed in accordance with the uniform cartridge contact time mentioned above simultaneously with the entry of the packaging target fabric on the vinyl film removal target, Determining the diameter of the fabric, determining the cartridge contact time corresponding to the diameter of the fabric, and setting the cartridge cylinder timer device at the cartridge contact time.

As described above, according to the method for controlling the side end joining device of the fabric vinyl wrapping machine of the present invention, it is possible to surely perform side joining processing on various fabrics of large and small diameters irrespective of the diameter of the fabric to be wrapped.

It is considered that the productivity improvement and the economic value of the present invention are considerably large considering that the delay in work or the damage to the fabric due to the occurrence of the side joint failure is considerable.
