Description

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for automatically welding textile synthetic materials along the periphery of a garment.

In the manufacture of garments having a synthetic thermal insert, the top synthetic material of the garment is associated with the insert by pinning, auxiliary sewing on the periphery of the garment, gluing, welding, and the like.

With pins, the materials to be joined are fixed on the whole flat garment and after assembly sewing the pins need to be removed.

Auxiliary sewing materials are welded along the periphery of the part a few mm from the periphery of the periphery. This has the disadvantage that it consumes thread and is laborious because it ties production capacity,

When bonding the materials to be bonded, they are glued to each other by means of an adhesive to the periphery or to the entire flat garment. This is unsatisfactory in terms of product quality.

In spot welding, the materials to be joined are heated to the plasticity temperature and formed together at the joint. The welds are placed intermittently, a few mm from the edge of the part circumference. Spot welding has so far been carried out by shifting the material relative to the welding tool, or vice versa, the welding tool has been applied to the parts to be joined. Such a procedure was very laborious, costly and inefficient.

This drawback is overcome by an automatic welding device for textile synthetic materials along the perimeter of the garment of the invention.

It is based on the fact that there are vertically movable welding tools in the gaps between the moving strips of the outer and inner conveyors, in front of which there are control sensors, each of which operates independently of the other sensors. Such a device enables automatic welding of garments made of textile synthetic materials, which significantly increases work productivity.

An example of the device is schematically shown in the attached drawing, where FIG. 1 shows a front view of the device and FIG. 2 in a sub-plan with an indication of moving garments. The support consists of an inner conveyor 1 and an outer conveyor 2. The support surface of the two conveyors 1, 2 is formed by a system of endless belts with gaps so that the strips of the inner conveyor 1 and the outer conveyor 2 aa coincide with each other, so that they are in the same position. In the interstices between the strips, vertically movable welding tools 5, e.g. thermocontact, in which the functional parts of each welding tool are heated to the desired temperature and set against each other from both sides of the welding gap. Similarly, ultrasonic or high frequency welding tools may be placed. In front of each welding tool 5 in a given gap, a control sensor 7, e.g. The photocell serves to independently control the associated welding tool 5. The strips of the inner conveyor 1 and the outer conveyor 2 have the same speed and move in accordance with the arrows indicated in FIG. 1. On the moving strips of the inner conveyor 1, the bonded materials of the garments 2, 4 are deposited so that their shapes coincide. The garment portions 3, 4 are further carried on the strips 3 into a slot formed by the strips of the inner conveyor 1 and the outer conveyor 2 where the parts 3 »4 are welded. When the front edge of the circuit reaches the position of the control sensor 7 5i, which makes a quick weld on the respective point of FIG. 2. The distance of the control sensor 7 from the welding tool p. ^e j subject to the rate of movement of the strips of the two conveyors 1, 2 and switching speed. The control sensor 7 reacts to the periphery of the garment circumference so that a pulse is generated when both the front and none of the circumferences of the garment part 3, 4 pass in the respective gap between the strips, resulting in unevenly spaced spot welds all over the garment circumference 2 ». the garment parts 3, 4 are clogged between the strips of the two conveyors 1, 2 to sleep to the operator's station, thereby closing the duty cycle.

The device according to the invention, with some modification of its process, can be advantageously used in connection with the corresponding device.

Claims (1)

201 054 this drawback removes an automatic welding machine for textile synthetic materials around the garment of the invention. The essence of this is that in the gaps between the movable strips of the outer and inner conveyor there are vertically movable welding tools, in front of which there are control sensors, each operating independently of the other sensors. The varnished equipment enables automatic welding of garments made of textile synthetic materials, thereby significantly increasing labor productivity. An example of an apparatus is shown schematically in the accompanying drawing, wherein Fig. 1 is a front elevational view and Fig. 2 is an elevational view showing moving garment die. The device consists of an inner conveyor 1 and an outer conveyor 2. The support surfaces of the conveyors 1, 2 are formed by an array of endless strips with gaps so that the strips of the conveyor 1 and the outer conveyor 2 coincide with each other, the boots being in the same position. In the gaps between the strips, vertically movable welding tools 5, e.g., thermo-contact, in which the functional contact parts of each welding tool are heated to the desired temperature and set against each other of the welding gap, are located in the inner conveyor-metal pristors. Similarly, ultrasonic or high frequency welding tools may be provided. In front of each welding tool 5, a control sensor 7 is disposed at a certain distance, e.g., a photocell, which operates independently of the associated welding tool 5. The belts of the inner conveyor 1 and the outer conveyor 2 have the same speed and move in the direction of the arrows indicated in FIG. 1. On the moving strip of the inner conveyor 1, the bonded materials of the metal parts 24 are deposited so that their shapes coincide. The garment portions 3, 4 are slipped on the strips into a slot formed by the strips of the inner conveyor 1 and the outer conveyor 2, where the parts 3, 4 are welded. The distance of the control sensor 7 from the welding tool p is conditioned by the speed of movement of the belts of the two conveyors 1, 2 and the switching speed. The control sensor 7 reacts to the periphery of the garment, so that the pulse is generated when the front or any edge of the periphery of the portion 3, 4 is in a corresponding gap between the tapes, thereby creating unevenly distributed spot welds over the entire garment 2 portion. the garments 3, 4 are sandwiched between the strips of the two conveyors 1, 2 to the operator station, thereby closing the duty cycle. The device according to the invention can be advantageously used in connection with a tapping device in a certain modification of its process.
