The present invention relates to a method for manufacturing a parser assembly, and more particularly, to a parser assembly dispensed by a machine for attachment of goods to each other and tagging of goods.

Numerous forms of parsers have been used to label products and tags.

One such form is known as the Sweep Teachment, which was introduced in 1963 by the Denison Manufactory Cheering Company.

The original Sweep Teachment Fassner is based on US Pat. No. 3,193,666, which was assigned to Denison and issued on September 17, 1963.

These fasteners were manufactured by molding individual parser assemblies, each of which connected a head and a cross bar with thin filaments, and a common runner as individual fastener necks. bar together.

The Fassner of Sweep Titchment has been used as a Sweep Teacher gun in US Pat. No. 3,103,666.

The variant of Denison Faasner in US Pat. No. 3,103,666 is assigned to Monarch Marking Systems Campani and described in US Pat. No. 3,185,367, issued May 25, 1965, under the name of F. L. Reiger et al.

However, Riger Faasner was not commercially successful, and Monarch used the Denison-type Faasner, as shown in Monarch's US Patents 3,650, 451 and 3,650,452, later patented in 1972 under the names of Bearland and Fink, respectively. Adopted. Denison Faasner was widely adopted in foreign countries as shown in US Pat. No. 3,652,004, which was granted to Batistaro Geo on March 28, 1972, which prioritized Italian applications.

Since the development of the basic 'sweet-teachment' fasteners, the kind of fasteners described in US Pat. No. 3,103,666, Monarch US Pat. No. 3,650,451, and Logio's Pat. No. 3,652, 004 It has been found in Denison that it can extend in the vicinity of the transverse bar and its filament joints and can be unexpectedly greatly improved.

In addition, in order to achieve satisfactory commercial production, it was necessary to simultaneously stretch the individual parsers of the combination.

Although the elongation of the extruded filaments, for example continuous nylon monofilament, is well known, the elongation of the molded part was not known in the invention of Denison.

Moreover, the elongation of the molded part was the middle part.

It was believed at that time that the formed filaments would rupture if they were stretched, for example, near the discontinuities of the connecting rod and the filament.

However, because the strength of the unexpected filaments is at the connection, this is disclosed in U.S. Patent Nos. 3,103,666; 3,650,451; 3,650,451; Filament ruptures caused by the use of the initial 'sweep-tetchment' fasteners of the unextended strains shown in 3,650,452 and 3,652,004 were prevented.

Elongated fasteners in the form of 'sweep tecturement' are now commonplace in the commodity trading industry and are available from virtually many suppliers, including Monarch and Loggio.

Denison has provided a number of methods for producing elongated 'sweep tectures', US Pat. No. 3,380,122, issued April 30, 1968; 3,444,597, May 20, 1969; No. 3,457,589 issued July 29, 1969.

As described in these patents, the assembly of the fastener is generally tapered slightly in the portion of the filament to ensure that it extends to the connection of the transverse bar and the filament.

US Patent No. 3,380,122; Although the manufacturing methods described in Nos. 3,444,597 and 3,457,389 do not provide suitable pasners, this method requires a suitable time interval, i.e. cycle time between kidney completions.

Moreover, while conventional methods are best suited for crystalline materials that can be easily stretched, such as nylon, they are not suitable for relatively rigid crystalline materials such as polypropylene.

It is therefore an object of the present invention to produce an elongated parser assembly for use in attaching goods and attaching tags to goods.

Another object of the present invention is to increase the production rate in producing elongated pasner by shortening the cycle time.

It is a further object of the present invention to achieve a production method which can be generally applied to the preparation of parsers from crystalline plastic materials.

In order to achieve the above and related objects, the present invention is to produce a parser assembly by shaping a set of connected individual parsers, applying controlled heat and simultaneously stretching the respective parsers.

According to one aspect of the invention the assembly is fed into an expander having jaws that grip the fasteners at both ends.

The filament is then subjected to controlled heat and at the same time the jaws are isolated enough to make the filament taut.

The jaws are then sequestered to stretch and then relaxed to dislodge the stretched assembly from the stretcher.

According to another aspect of the present invention, the fastener may be produced while the filament is heated when the mold is separated in a molding machine having a separable portion.

According to another aspect of the invention, it is preferable to use an infrared radiator for heat control, which has an effect of directly applying heat to the connection portion of the filament together with the components at both ends thereof.

According to another aspect of the invention, the filament has a taper over a portion of each length to extend over the joining portion of the transverse bars.

However, the filament can be of another shape, including a cylindrical shape.

According to another aspect of the present invention, the paasner is preferably redirected due to elongation of its molecular structure and is selected from nylon, polystyrene polypropylene, polyester and acetal resin.

Referring to the drawings, FIG. 1a shows the assembly 10 from individual parser 20-1 to 20-n produced in accordance with the present invention.

The individual parser, for example the first parser 20-1, has a transverse bar 20c connected to the head 20h by the filament 20f.

All of the fasteners 20-1 to 20-n are connected to the runner bar 11 by individual neck portions 20n extending from the transverse rod 20c.

Although the filaments 20f from the fasteners 20-1 to 20-n appear cylindrical over most of the length starting at the transverse bar 20c, they are typically slightly tapered.

This is evident in the partially enlarged view of each fastener 20-1 shown in FIG. 1B.

The minimum diameter is about 0.220 inches in the portion A located about 0.660 inches from the connecting rod 20c of the transverse bar 20c and the parser 20-1 in the pasner 20-1 of FIG.

The diameter of the filament 20f is gradually increased to 0.240 inches in B, 0.250 inches in the C portion, and 0.260 inches in the D portion.

Elongation is evident in the partially enlarged view of each fastener 20-1 shown in FIG. 2A.

The device 30 is equipped with an external jaw 31 and an internal jaw 32.

The outer jaw 31 has an interior 31r for receiving one end of the fastener to be stretched; The inner jaw 32, on the other hand, has a similar interior 32r for receiving the other end of the fastener.

In the case of an unextended Paasner assembly, only its first membrane 20-1 'is shown in Figure 2a, the Faasner head 20h' is in the interior 31r of the outer jaw 31, The traveling rod 11 'is in the interior 32r of the inner jaw 32.

The outer jaw 931 has a passage 31c for receiving a portion of the filament 20f near the head 20h 'side.

The inner jaw 32 has a similar passage 32c.

In the specific mass production of FIG. 2A the inner jaws 32 are stationary and the outer jaws 31 are isolated from the inner jaws by, for example, hydraulics.

Only half of the device 30 is shown in FIG. 2A and the other half similar to this is coupled to the set in the jaws 31, 32 with the isolator 22 to simultaneously elongate another set of raw fasteners. You should understand what is used to.

The jaw after the fastener assembly connected by the removable connector 22 is transferred between the jaws 31, 32, for example, the fastener 20-1 ′ shown, is transferred to the device 31. An external jaw, such as 31, acts to tighten the pasner, ie it is moved from the initial position 31a to the intermediate position 31b as shown.

In general, the external jaw 31 is extended by moving it to the position of 31f. A regulated heat source 40 is used to facilitate and facilitate the elongation of crystallized plastic materials having elongation resistance, such as polypropylene.

The regulating heat source 40 has a holder 41 and a quartz infrared lamp 42, which will be described in detail later.

Heat from the lamp 42 is first applied when an external jaw is in its position 31a.

This heating action will continue to be applied until jaw 31 is moved to its last position 31f to produce the pasner shown in FIG. 1a.

After the end of the stretching, the jaws 31 are relaxed so that the extended pausner from the device 30 is released.

The passage 32c of the inner jaw 32 surrounds the pasner neck 20'n, thus allowing the gripping action of the temperature 32 to be on the running rod 11 '.

By wrapping the neck 20'n, the neck is prevented from being inadvertently stretched, while the gripping of the traveling bar 11 'prevents accidental damage to the transverse bar 20c'.

In the aspect of FIG. 2B, the lamp 42 is located in an end mounting 43 that can be adjusted to directly heat the desired portion of the filament 20f.

The end mounting hole 43 is arbitrarily adjustable to adjust the direction of infrared radiation from the lamp 42.

A partial perspective view of the lamp 42 is shown in FIG. 3.

The quartz tube 42q surrounds the resistance coil 42c having the terminals 42t-1 and 42t-2.

Above the coil 42c is an internal reflector 42r which introduces infrared radiation at a right angle.

Lamp 42 is New York 11415, Cuegadon; It is a kind known as an infrared heating lamp available from Hugo, Ann Kanman of Keen Bullbird 125-10.

It has an infrared radiation range of 2 to 5 microns and provides a temperature between 600 and 2000 ° F.

The temperature H of the heat source 42 and the time T at which the Pasner is subjected to the thermal effect are preferably utilized such that the occurrence of the thermal effect and the temperature are lower than the values causing dissolution of the Pasner.

The internal reflector 42r of the heat source 42 applies about 85% of the radiant energy to the product.

Another form of the fastener is shown in jaw 35 of FIG. 4A.

In each of the fasteners 24-1 in FIG. 4, the filament 24f is almost cylindrical throughout its length. Because of the heating effect H, elongation is as shown in Fig. 4B.

Since the filament has a cylindrical cross section, its elongated portion is also almost cylindrical.

However, near the head 24h, there is a slight taper t area.

Although the cylindrical filament 24f is difficult to adjust, the molding cost is not large and the possibility of occurrence of excess thickness portions that cause unexpected rupture during elongation can be avoided.

As shown in FIG. 5, the fastener assembly 50, which is elongated using the cylindrical filament 50f, is coupled to the transverse bars 50c-1, 50c-2 and the respective transverse bars at both ends. It has traveling rods 11-1 and 11-2. One of the traveling rods 11-1 and 11-2 can be used to feed the conveying device according to the above-mentioned patent.

The other running bars 11-1, 11-2 give the assembly 50 strength and are convenient to handle them during the stretching operation while applying controlled heat.

One of the traveling rods can be dislodged by removing it after the stretching operation is finished.

It is evident that an auxiliary running rod can be used in other types of fasteners and devices, which facilitates stretching operations while applying controlled heat.

Another kind of raw fasteners used in the present invention are shown in FIGS. 6A-6C.

The unextended paasner 25 shown in FIG. 6A has its minimum diameter 25d at a short distance from the transverse bar 25c.

In FIG. 6B it has an almost cylindrical filament 26 of minimum diameter at the middle portion 26d of the fastener 26.

In Fig. 6C, the connecting portion between the tapered portion 27t-1 and the front tapered portion 27t-2, starting from the transverse bar 27c, is gradually reduced in diameter.

When constant heat is applied to the filaments 25f, 26f, and 27f from Figs. 6a to 6c, the elongation begins at the minimum diameter portions 25d, 26d, 27d, and then Proceed in the minimum radial direction.

Thus, in the case of FIG. 6C, since the second tapered portion 27t-2 has a stepped portion higher than the first tapered portion 27t-1, the stretching is performed before the expansion occurs in the region of the front tapered portion 27t-2. It happens first at (27j).

Although various aspects of the present invention have been described in the drawings and the specification, the above-described detailed description is for illustration only, and it is to be understood that the various parts shown and described herein may be modified in various forms or replaced with equivalents. It should be understood that there is no escape from the category.
