本発明は自動梱包機における梱包バンドの端末
接合方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for joining the ends of packaging bands in an automatic packaging machine.
自動梱包機においては、従来梱包用のバンドと

来行われて来た端末部分の接合方法が厚手のもの
にしか適用できないものであるため、バンドの費
用がより高いものになるという問題点がある。 In automatic packaging machines, thermoplastic plastic bands have conventionally been used as packaging bands. This is because both end portions of the band wrapped around the object to be packed can be joined by thermal welding, which saves the trouble of tying them one by one and can be done quickly. However, with such thermoplastic bands, the thermoplastic plastic itself is expensive, and the conventional method of joining the end portions can only be applied to thick bands, making the band more expensive. The problem is that it is expensive.
然して、従来のバンドの両端末部分の接合方法
は、第１図乃至第４図の工程によつて行われるも
のである。 However, the conventional method of joining both end portions of a band is carried out by the steps shown in FIGS. 1 to 4.

る。 First, both end portions 1 and 2 of the thermoplastic band to be welded are overlapped, and the overlapping portion is pulled from both sides using an appropriate member (not shown). Next, above the overlapped part,
A heating tool 5 having several parallel elongated heating blades 6
The heating blade 6 faces along the tension direction of the band. (Fig. 1) Next, push down the heating tool 5,
Both end portions 1 and 2 of the overlapped band are melted and penetrated by a heating blade 6. (Fig. 2) As a result, several parallel elongated holes 3 are formed in both end portions 1 and 2 of the overlapped band, and both end portions 1 and 2 are melted into the respective peripheral walls of the elongated holes 3. A continuous fusion zone 4 is formed. (FIG. 5) Also, at this time, a slight gap 7 is created between both end portions 1 and 2 of the band. Next, the heating tool 5 is raised and the heating blade 6 is pulled out (Fig. 3), and then the end portion 1 of the band,
The overlapping portions of 2 are sandwiched and pressed from above and below in a sandwich-like manner using pressing bodies 8 and 9 to form a molten portion 4.
Squeeze the protruding parts from the surface of the end parts 1 and 2 of the band, and press both end parts 1 and 2 of the band.
At the same time, the thickness of the melted part 4 is made to be as uniform as possible. (FIG. 4) FIG. 6 is an enlarged view of the elongated hole 3 in this state.

を有するバンドだけしか使用することができなか
つたのである。 However, with this joining method, only thick materials could be welded. When passing through the heating blade, both end portions 1 of the band,
This is due to the fact that 2 are overlapped and the both sides of the overlapped portion are simply stretched. In other words, even if the overlapped parts are pulled together from both sides using appropriate members, this does not mean that the overlapped parts are completely in close contact with each other, so the degree of adhesion in the center will inevitably vary. is weak, so when the heating blade 6 penetrates the end portion 1 of the upper band and attempts to contact and break through the upper surface of the end portion 2 of the lower band, at this time the lower band A gap is created between the end portion 2 and the end portion 1 of the upper band, and unless the band is very strong, the gap becomes too large and the two end portions cannot be welded together. As a result, only bands of considerable thickness could be used.

る。 Furthermore, FIG. 7 shows an explanation for welding a thin band using the conventional joining method, in which a heating blade 6 passing through the end portion 1' of the upper band is used to weld the lower band. When an attempt is made to contact and break through the upper surface of the end portion 2', a large gap is created between the two end portions 1' and 2', which prevents the fused portions of the two end portions from connecting, and eventually the two end portions Indicates that it is not possible to join the parts.

なるものである。 Next, the heating tool 17 is pushed up and several heating blades 16 are used to melt and penetrate the overlapping portions of both end portions 10 and 11 of the packaging band, forming several parallel long holes 12, and at the same time Melted part 13 on the peripheral wall
form. In this case, the heating blade 16 enters into the groove 14 of the stand 15 (11th
figure). In order to penetrate the heating blade 16 into both end portions 10 and 11 of the packing band, as shown in FIG.
The heating blade 16
When inserted through the lower end portion 11 and inserted into the upper end portion 10, the two do not separate. Further, following the step shown in FIG. 11, the heating tool 17 is lowered and the heating blade 16
Pull it out (Figure 12). This completes the entire process, and as shown in FIG. 13, several parallel long holes 12 are formed in both end portions 10 and 11 of the packing band.
Moreover, a melted part 13 is formed on the peripheral wall of the elongated hole 12, in which the parts melted by the heating blades 16 at each end of the packaging band are connected, so that both end parts 10,
11 are joined. FIG. 15 is an enlarged view of the elongated hole 12 in this state, and both end portions 10 and 11 of the packing band are stretched over the entire surface of the combined surface of the base 15 through tension on the curved surface. Because they are maintained so that they do not separate, they do not separate when the heating blade 16 is inserted, and therefore the parts melted by the heating blade 16 on both sides are properly connected, resulting in a thick Both end portions can be joined not only with packing bands but also with extremely thin packing bands, and since there is no gap between both end portions as in the conventional method, the melted portion enters the gap between both end portions. If a part of the molten part becomes thin, no sagging occurs, and therefore there is no need to use a pressing body to press the molten part from above and below to make the thickness uniform, and the heating blade 16 can be pulled out at the same time as the heating blade 16 is pulled out. The state is the same as that shown in FIG. 6, that is, the melted portion has a substantially uniform thickness throughout the top and bottom.
