Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an apparatus for processing a perforation for dividing a packaging container formed of plastic or the like.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, a perforation 2 for dividing a packaging container 1 formed of plastic or the like, which is formed by integrally molding a plurality of pieces, has a processing blade 3 as shown in FIG. Has been processed by a perforation processing apparatus which supports the vertical movement. In such a perforation processing apparatus, the processing blade 3 is provided with slits 3b at predetermined intervals in a horizontally arranged blade portion 3a, and is provided at a predetermined position of the packaging container placed on the table 4. The processing blade 3 is lowered to process a perforation. In this case, the blade portion of the processing blade 3 is configured to contact the table 4. In order to protect the blade portion 3 a, the portion of the table 4 that the processing blade 3 contacts is formed of a relatively soft material such as epoxy resin. It is being done.

[0003]

[Problems to be solved by the invention]

However, in order to machine a perforation using the above-mentioned conventional machining blade having a horizontal blade portion, it is necessary to apply a pressure of, for example, about 200 kgf / cm ^2, and the portion where the machining blade 3 of the base 4 contacts the machining blade 3 is required. No matter how soft the material is, the blade portion 3a is pressed against the table 4 at high pressure, so that the table 4 or the blade portion 3a is significantly worn or damaged, and there is a problem that frequent polishing or replacement is required. .

[0004] Therefore, an object of the present invention is to provide a perforation processing apparatus capable of processing a perforation with a pressure smaller than that of the conventional art, and capable of almost eliminating wear of a blade portion.

[0005]

Means for Solving the Problems The object of the present invention is to provide a support portion for supporting a plurality of packaging containers formed continuously and integrally at a predetermined position; A processing blade for processing a perforation for dividing the packaging container is provided so as to be able to approach and separate from each other, and the processing blade includes a plurality of serial blade portions forming a perforation, and between each adjacent blade portion. It has a notch groove extending in the approaching / separating direction, and each of the plurality of blade portions has a pointed end, and the support portion has a gap through which the processing blade can enter the packaging container support surface. This is achieved by a packaging container perforation apparatus.

The processing blade may be formed in a waveform corresponding to a waveform perforation.

[0007]

[Embodiment of the invention]

 Preferred embodiments of the present invention will be described below with reference to the drawings. Throughout the drawings, including the conventional technology, the same components are denoted by the same reference numerals. FIG. 1 is an enlarged front view showing the processing blade, and FIG. 2 is a side sectional view showing a perforation processing apparatus provided with the processing blade of FIG. FIG. 3 is a front view showing a second embodiment of the processing blade, and FIG. 4 is a perspective view showing a third embodiment of the processing blade.

As shown in FIGS. 1A and 1B, a perforated processing blade 5 used in the present apparatus has a plurality of serial blade portions 5 a formed corresponding to the perforations 2. are doing. In addition, a cut groove 5b for forming a perforated connection portion is formed between the adjacent blade portions 5a. Further, each of the blade portions 5a having the cutting blades has a point 5c. In the drawing, the blade portion 5a is formed obliquely in a straight line, but may be formed obliquely in a curved shape. In the example of FIG. 1A, the blade portion 5a is inclined in the opposite direction at the center in the width direction and is symmetrical. On the other hand, as shown in FIG. 1B, the direction of the inclination of the blade portion 5 a can be the same over the entire processing blade 5. Alternatively, blade portions having different inclination directions may be mixed at an appropriate ratio.

As shown in FIG. 2, such a processing blade 5 is disposed to face a supporting portion 6 that supports a packaging container 1 in which a plurality of continuously formed integrally molded containers are held at a predetermined position. In the example of FIG. 2, the processing blade 5 is supported so as to approach or separate from the support portion 6, and is driven in a vertical direction in the figure by a driving device (not shown).

The support portion 6 has a slit 6 a into which the processing blade 5 can enter when the processing blade 5 moves downward. That is, when the processing blade 5 descends from the raised position and the pointed tip 5c pierces the packaging container and penetrates, the blade portion 5a can enter the narrow gap 6a. The penetration depth of the blade portion 5a into the narrow space 6a is regulated by the groove depth of the cut groove 5b.

Although the tips 5c of the processing blade 5 shown in FIG. 1 are provided so as to be arranged on a horizontal line, as shown in FIG. 3, they may be provided on a straight line in which the tips 5c are inclined. In the processing blade 5 shown in FIG. 3, the cutting groove 5b is gradually deepened in accordance with the inclination of the edge of the blade portion. In addition, the tips 5c can be provided so as to be arranged on a straight line or a curve having an inclination different from the inclination of the edge of the blade portion, or they are arranged at different positions in the direction of approaching to and away from the support portion 6. It can be provided in various forms.

When a plurality of corrugated perforations (not shown) are formed in the integrally formed packaging container 1, the shape of the processing blade 5 is changed according to the corrugated perforations as shown in FIG. On Form a waveform.

[0013] In the perforation processing apparatus having the above-described configuration, the point 5c serves as a starting point of the perforation, and the perforation is cut by a continuous blade (cutting edge) from the starting point of the perforation. Therefore, the perforations can be processed with a smaller pressure than the conventional apparatus. In addition, if the tips 5c of the plurality of blades are provided at different positions in the direction of approaching / separating from the support portion 6 and the resistance received at the start of the tearing of the packaging container is dispersed, the perforation is performed with a smaller pressure. Energy saving of driving measures.

Further, since the slit 6a is formed in the support portion 6 so that the processing blade 5 can enter the slit 6a, the blade does not hit the table unlike the conventional apparatus, and the blade is worn. And damage are greatly reduced.

[0015]

[Effect of the invention]

 As is apparent from the above description, according to the perforation processing apparatus according to the present invention, the processing blade includes a plurality of serial blade portions forming a perforation, and A notch groove extending in the separating direction was formed, and each of the plurality of blades was provided with a sharp point, so that a narrow space through which the processing blade could enter the support for supporting the packaging container was formed. Does not hit the support part, thereby making it possible to almost eliminate the wear of the blade part, form the starting point of the tear by the pointed end, and cut the perforation by the blade part (cutting blade). Perforations can be processed with pressure.

In particular, if the tips of the plurality of blades are provided at different positions in the approaching / separating direction so as to disperse the resistance force received at the start of the tearing of the packaging container, the perforation processing can be performed with a smaller pressure. It can be effective in saving energy of driving measures.
