Description

8102359-2 10 15 20 25 30 35 2 The number of label sticks on a connecting rod is about 25-50. Threads 3 with a relatively short length of about 7-20 mm allow proper anchoring of the label sticks. If the wires 3 are longer than 20 mm or more, they have a tendency to deflect, so that the heads 1 change their positions without any resistance, whereby the wires 3 and the heads 1 become entangled in each other. For example, if the needles are made of nylon, they have a relatively stable shape immediately after the forming and stretching processes, but their threads 3 become softer and softer as they gradually absorb the surrounding moisture. As a result, the sets of knitting needles become entangled with each other when they come in contact with each other, or the arrangement of knitting needles in each set becomes irregular. As far as the concrete practice is concerned, after shaping the kits, a number of these kits are usually packed in a box for transport. Tangled heads on the batches A1 and A2 according to Fig. 3 lead to the fact that if you want to take out one batch, several batches are included. Thus, before using a batch, it must be freed from its entangled state.

A similar entanglement occurs when a batch is temporarily stored, during its use, in the box and then taken out for reuse. When using the label sticks, a batch of them is inserted into a labeling machine. The needles deflect when they are to be inserted into the goods and have their heads entangled in each other, making it difficult to distinguish a label stick already inserted in the goods from the rest of the kit.

To eliminate these inconveniences, a method has been proposed in which the heads of adjacent label sticks are connected by means of a connecting string.

This string is stretched and torn off, however, when a stick which has been inserted into the article is to be separated from the set, whereby a "beard" arises on the surface of the head of the stick thus separated. If a nylon knitting connecting strand is stretched until it is torn, the connecting thread will also be stretched, to about 4-5 times its original length, so that a substantially long "beard" "will protrude from the surface of the head of the stick. There are many different items, to which price tags are attached by means of label sticks. Knitted or woven fabrics have their threads captured by the above-mentioned "beard", which threads can then be cut or frayed. It is remarkably difficult to make the connecting string thinner in order to eliminate the defect in the product caused by the "beard". This is due to the fact that the connecting strand has a diameter limited to 0.1-0.15 mm due to the present molding technique. A set of label sticks, the connecting strand of which is partially punctured, is exposed to a more complicated entanglement than the first described set of label sticks, which have no connecting string. Furthermore, sets of connecting string between the stick heads require a more complicated shape. , which thus becomes more expensive and has a shorter service life. Arranging a connecting string thus leads to several problems, independent of string even thickness, so that this use is undesirable.

The present invention has for its object to eliminate the above-mentioned disadvantages of the prior art. A main or first object of the invention is to provide such a set of label sticks which are not subject to entanglement problems and which do not have a connecting strand between the heads of the label sticks. A second object of the invention is to provide such a set of label sticks, which are of the dense type, where a large or increased number of label sticks per unit length of the connecting rod can be created by means of a small mold. A third object of the invention is to provide such a set of label pins which has little deflection of the threads of the label pins, and a set which is compact but still has an attractive appearance and is easy to make. manage. A fourth object of the invention is to provide such a set of label sticks, which has a low production cost per label stick and which allows continuous use of a number of label sticks.

According to the invention, the set end dimensions are achieved with such a characteristic set of label inserts that the thickness of each head amounts to 0.7-1.0 mm and that the distance between adjacent heads of the pieces is from 0.2 mm to less than 0.7 mm, whereby sticks belonging to one batch are prevented from penetrating into the spaces between sticks belonging to another batch and thereby becoming entangled in each other.

The invention is described in more detail in the following with reference to the accompanying drawings. Figs. 1 (A) and 1 (B) are front views of the heads of conventional label sticks.

Fig. 14 is a front view of a label stick with a thread stretched over its entire length.

Figures 4 and 5 show a first embodiment of the invention, where in Figure 4 only three label sticks P1, P2 and P3 are shown for the sake of simplicity. The label stick P1 has a head 1, a transverse rod 2 and one of these parts connecting wire 3. The label stick P1 is fastened to a connecting rod 5 by means of a bracket 4, so that it forms a right angle with the connecting rod 5. The label stick P1 forms together with the needles P2, P3 etc, which are attached in the same way, a set P of label needles. The set P consists, for example, of 25-50 needles P1, P2, P3, etc., and of 100 needles in a set, which has the longest connecting rod 5.

The kit is formed in one piece from a synthetic resin, such as nylon or polypropylene. Prior to the forming process, the wire has substantially the same diameter as the cross bar and is relatively rigid, so that it can be broken during bending.

Especially when the label stick is attached to a product by means of a labeling machine, the cross bar 2 is inserted into the product in a state where the wire is deformed so that it is substantially parallel to the cross bar 2. Since the cross bar 2 has been inserted into the product, the wire 3 has resistance to return from its deformed shape; it is folded in other words by the deformation. For this reason, the wire 3 is stretched after the forming process, so that it is imparted by the orientation of the polymer molecules to such a property that it becomes flexible but is still difficult to fold.

Before it is stretched, the wire 3 can have the tapered shape shown in Fig. 6 (A) or a shape shown in Fig. 6 (B) without taper.

The thickness E of the head 1 is usually 0.7-1.0 mm, which is substantially equal to the diameter of the cross bar 2. Otherwise, the crossbar 2 can have a diameter of about 1.0 mm, so that it cannot be deformed to a V-shape when the label stick is inserted into the product. The distance Å between the head 1 and the adjacent head 1 'is usually from 0.2 mm to less than 0.7 mm, preferably 0.2-0.5 mm, and preferably 0.2-0.3 mm. If the distance 1 falls within one of the above-mentioned areas, the strength of the walls defining the mold space between the heads 1 and 1 'can be kept at a sufficient level so that no problems are created in the molding process. If said distance is from 0.2 mm to less than 0.7 mm, this distance between two adjacent heads is less than the thickness E of the heads, so that the head in a series of label sticks hardly slips into the space between adjacent the heads of each other in the second series of label sticks so much that the series intertwine, even if the series are in mutual contact with each other. Furthermore, even if a label stick moves in the transverse direction, the adjacent label stick simultaneously changes its position corresponding to the displacement of the first-mentioned stick, if the distance l is from 0.2 mm to less than 0.7 mm, so that the series as a whole behaves like a train, whereby displacement of individual label sticks and irregularities in the arrangement can be eliminated.

This in turn is effective in preventing entanglement between the series. If said distance is 0.2-0.5 mm, preferably 0.2-0.3 mm, the head of the label sticks in a series assumes a state in which they, so to speak, adhere to each other and are in a single piece, so that individual label sticks can no longer behave independently of each other, thereby further reducing the risk of entanglement between series.

If a labeling machine is loaded with a series and activated, its gear device is brought into engagement with the bracket 4 for feeding sticks one after the other and for cutting off the brackets 4 one after the other, so that the stick can be inserted into the product. In other words, the bracket 4 has the function of feeding the sticks in after the other and to serve as a passage when a molten resin is injected into a mold. With this in mind, therefore, the bracket 4 must have such a diameter that it does not create problems in the resin injection and can be cut through without difficulty. The connecting rod 5 also forms the guide passage for the resin, when this resin is injected into the mold space for forming label sticks. The connecting rod 5 is therefore suitably round, square, semi-oval or hexagonal: Since in the first embodiment according to Figs. 4 and 5 the distance Ä between the heads of the label sticks P1, P2, P3 etc., forming a series P, is thus less than the thickness E of the heads it is possible to prevent the heads of one series from slipping into the spaces between the heads of another series, even if several such series are kept in contact with each other, thereby preventing entanglement of the heads and / or the wires in each other.

The small space Å between the heads also prevents irregularity in the arrangement of the heads in the series.

Fig. 7 is a plan view of the heads of label sticks in another embodiment of the invention. In this embodiment, the thickness E of the heads is greater than the distance Å between adjacent heads, as was the case in the first embodiment, but the heads 1a are deformed in the middle, so that they have a boomerang shape. The space between adjacent heads 1a and 1a 'thus also has a boomerang shape. Seen from the side, however, the front end E of the head 1a 'is covered by the front end 1 of the adjacent head 1a, so that it cannot be seen from the side. Consequently, the heads are arranged as if they had no space in the side view.

Since in this embodiment the thickness t of the heads of the sticks is greater than the distance & between the heads of adjacent label sticks, and since the heads are arranged as if they had no space in a side view, the heads and / or threads are more reluctant to get entangled in each other even if several series are kept in touch with each other. Since the heads are deformed at their center so that their direction of extension changes, as shown in Fig. 7, the heads in one series can not move as far as to the middle portions of the heads in another series. , even if the heads in the two series come in between each other.

Consequently, it is possible to further prevent entrapment and to easily lift the entrapment, if any. Although the head of a stick in a series, e.g. the head 1a ', is displaced laterally and away from the remaining heads, its front end E comes into contact with the edge y of the other head 1a, so that irregularities in the arrangement' of the heads further can be counteracted. Fig. 8 is a plan view of the heads in a third embodiment. The head 1b has on both its front and its back such oblique surfaces 3 and Q, which slope outwards from the extension of the trees to the side edges of the head, symmetrically with respect to the extension of the wire. Also in this third embodiment, the thickness E of the heads is greater than the distance Å between adjacent heads, and the heads have a parallelogram shape in section.

The consequence of this is that a head cannot move as far as half the distance of the space between the heads, if the former head slips into this space, so that the heads are prevented from completely overlapping each other and can, if they come in between each other, separated without any difficulty.

Furthermore, in this third embodiment, the original thickness E of the heads at the side edges can be reduced by Q-gg molds, the heads are thickened to a corresponding extent, whereby the mechanical strength of the mold is improved. In this embodiment it is further possible to easily remove the mold after the resin has been injected into the mold and. In this way, the walls of the mold space, as molding has taken place.

Fig. 9 shows a fourth embodiment, where the left and right halves of the heads during the shaping are inclined in the same direction from the central areas of the heads, whereby the heads get a V-shape in top view. The heads are thus arranged as if they had no space, seen from the side, in the same way as in the second embodiment according to Fig. 7, whereby the heads can be further prevented from entanglement. between each other. Furthermore, since the gaps between the heads change direction, a head can not move as far as the center of the gap between the other heads, even if such insertion takes place, whereby the inserted heads can be easily separated from each other. In the series according to Fig. 9 it is further the case that even if a label stick moves laterally, out from the space between adjacent heads, its head lc will at the point of inflection g touch the front end f of another head ld, so that Irregularities in the arrangement of label sticks can be prevented and a stable arrangement is always maintained.

The description of the arrangement of label sticks in a series of the 1-4 embodiments has been made with reference to side and top views. However, the shape of the label sticks, seen from the front, is also important for preventing entanglement. This shape can vary as follows. According to Fig. 5, which shows the first embodiment, the head 1 has been designed so that the lower edges g and h gradually move away from the cross bar 2 as they move away from the wire 3. As a result, the entanglement of the heads 1 can be automatically lifted by the inclination of the lower edges g and Q.

Fig. 10 shows a fifth embodiment, in which the head 1 has substantially the same shape as a Braun tube with curved lower edges g and h. Consequently, the entangling effect of this fifth embodiment is more prominent than in the embodiment illustrated in Fig. 5 with straight lower edges 5 and h.

Fig. 11 shows a sixth embodiment, in which the head 1 is shaped so as to tip to the left from its axis.

Consequently, the right lower edge g is steeply inclined. If such label pins become entangled between each other, for example if the head of another label stick is caught by the lower edge g, this entanglement can be easily lifted, since the inclination of the lower edge g is steep. If, on the other hand, the head of another label stick is caught by the other lower edge h, the head 1 is set straight up to the position shown in a dashed line, so that the heads can be released from their tangled positions. The lifting of a entanglement can thus be facilitated by tilting the head either to the right or to the left.

Figs. 12 (A) to 12 (G) show seventh to thirteenth embodiments. In the seventh embodiment according to Fig. 12 (A), the main stick of the label stick is formed into an inverted triangle shape. In the eighth to twelfth embodiments according to Figs. 12 (B) -12 (D), the head of the label stick is formed into a sector shape, a semicircular shape and a heart shape, respectively. In the eleventh to thirteenth embodiments according to Figs. 12 (E) -12 (G), the lower edges g and h of the head are tapered in the direction of the wire 3, as can be seen, for example, in Figs. 12 (E). The head according to any one of Figures 12 (A) -12 (G) may be formed either symmetrically with respect to the center axis of the trees, as shown in Fig. 10, or with a slope to the left or right with respect to the center line of the trees, as shown in FIG. appears in fig ll. Tilting of the head according to Fig. 12 (B) to the left in relation to the center line of the wire is shown in Fig. 13. In this example, the lower edge g of the head 1 lies substantially on the extension of the trees 3. Consequently, the entangling effect of the head is more prominent.

Thus, if the head 1 is caught on the lower edge Q, it is tilted to the right to the position shown in broken line, so that it is released from its caught position.

To return to the first embodiment according to Figs. 4 and 5, an unstretched portion 3 'is left there between the head 1 and the wire 3. This unstretched portion 3', if left, acts as a buffer, whereby the advantage arises that it is possible to arrange different label sticks, the threads 3 of which have different lengths, depending on their different stretches from the state of unstretched label sticks. Since the unstretched portion 3 'serves as a buffer, no abnormal tensile force occurs on the corresponding wire 3, so that this wire can be prevented from breaking depending on the stretching. In Fig. 14, the unstretched portion 3 'is completely stretched so that the wire 3 has a uniform diameter from the cross bar 2 to the head 1. By stretching the wire 3 over its entire length in this way, the strength and flexibility of the wire can be increased despite the thinning. , so that the attachment of the stick by means of the labeling machine can be easily performed. At the same time, the price label can be nicely affixed to a product, although the head 1 has a shape which allows movement in relation to the wire.

As described above, the invention is characterized in that the distance 2 between the heads 1 of the label sticks is smaller than the thickness t of the heads, so that this distance is usually from 0.2 mm to less 0.7 mm, preferably 0.2-0.5 mm. and preferably 0.2-0.3 mm. By fulfilling the expression E> Å, it is possible to effectively prevent the head of a label stick belonging to a series of label sticks from penetrating so into the space between the heads of label sticks, belonging to another set of label sticks, that the sticks become entangled in each other.

For the sake of comparison, kits with 100 label sticks with the gap å = 0.6 mm, in accordance with the first described embodiment, and kits with 100 label sticks with E É Å according to the prior art (respective kits of the two types have thus the same number of label sticks) were placed randomly in different boxes and shaken gently for a predetermined period of time by means of a reciprocating shaker. Then the mean values were calculated from the number of batches which, after removal from each box, were tangled with another series. The result was as follows: 8102339-2 10 15 12 The invention | Prior Art 0.4 I 2.6 From this result it appears that entanglement is substantially prevented by the invention, in contrast to the known sets of label sticks, and can be easily eliminated. Furthermore, since according to the invention the difference E> Ä is fulfilled, as described earlier, a denser set of label sticks can be produced, so that a larger number of label sticks are present on each connecting rod and so that a number of label sticks can be used continuously. Furthermore, since the label sticks are tightly attached to the connecting rod, which has also been described previously, the kit becomes compact and label sticks can be produced without irregularities in the arrangement, so that the kits have a neat appearance and are easy to handle. Since the label sticks in the kit according to the invention can be fastened tightly, the production speed of the label sticks can be increased and the production cost of each label stick reduced.
