Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a V-groove cutting device for a foamed resin plate for cutting a V-shaped groove for bending in a foamed resin plate used for a folding box, for example.

[0002]

[Prior art]

 A foamed resin plate made of styrene resin or the like is often used as a material for folding boxes, etc. When used as such a box material, a V-shaped groove is cut from the back side leaving a little front side for bending. . The formation of the V groove has conventionally been performed by a method using a cutting blade in which the tips of two thin blades are arranged close to each other in a V shape.

[0003]

[Problems to be solved by the device]

 In the case of using the above-mentioned two conventional V-shaped cutting blades, a slight flat portion (S) is often formed at the bottom of the V groove as shown in FIG. 4 in order to obtain a good bending state. However, since this flat surface (S) has an extremely short width, it is difficult to make a blade, so the flat surface (S) will be cut when the string-shaped chips with a substantially triangular cross section are removed. is there.

In this case, the flat portion (S) may remain in the V groove without being torn, or even if the flat portion (S) is torn, chips may remain attached to the V groove due to static electricity. However, there was a problem that it was often necessary to manually remove it later, resulting in cost increase due to personnel costs.

In addition, string-like chips may not be guided to a predetermined waste collection place and may be caught in various parts of the machine, resulting in a failure.

An object of the present invention is to completely remove the string-shaped chips and guide them to the waste collection place in order to solve the above-mentioned conventional problems.

[0007]

[Means for Solving the Problems]

 This invention for achieving the above-mentioned object is to make a thin plate and make a V-shaped cross section and a non-linear line behind a grooving main body in which the tips of two elongated plate-shaped grooving blades are brought close to each other and attached in a substantially V shape. A chip removing member of appropriate length having a ridge line is made to approach one end of the ridge line to the rear end of the tip of the two groove cutting blades, and the chips removed along the inside of the ridge line of the chip removing member are removed. It is a V-grooving device for foamed resin plates, which is attached so as to face a predetermined chip storage portion.

[0008]

[Action]

 By removing the string-like chips generated by the V-groove cutting along the chip removing member, the flat surface (S) of the groove bottom is forcibly cut off, and further, the adhesion due to static electricity is prevented and the V-groove is cut into the V-groove. It will not be left and will be guided to the specified chip reservoir.

【Example】

 The present invention will be described in detail below with reference to the exemplary drawings. FIG. 1 is a side view showing a use state of a V-grooving device for a foamed resin plate according to the present invention, FIG. 2 is a plan view of the device, and FIG. 3 is a front view of the same. Is.

(1) is a foamed resin plate, a cosmetic film is laminated on the upper surface in the state shown in the figure, and by a pair of upper and lower feed rolls (2), (2) provided at several places in the traveling direction. F Move in the direction indicated by the arrow.

(3) is a grooving main body, which is composed of a substantially vertically long rectangular block body, and the range of a triangle from the upper end to the side surface on either side of the front surface (3a) is parallel to the front surface (3a). A stepped-down surface (3b) that is cut off is formed, and a trapezoidal chip removing member attachment portion (4) is formed at the center of the upper end of the back surface as seen from the back surface.

(5) and (6) are blade mounting grooves, which are formed on the front surface (3a) and the step-down surface (3b) of the grooving main body (3) when viewed from the front side from the upper end to the side surface. It is dug into a pair of left and right in a letter shape to a depth almost the same as the width of the groove cutting blades (7), (8).

The grooving blades (7) and (8) are formed by cutting a long and narrow steel plate into a knife shape. When viewed from the front, the tips are slightly protruded from the upper end of the grooving body (3). With the clearance of, they fit close to the tool mounting grooves (5) and (6), and the captive screws (9) and (9) set up on the front surface (3a) and step-down surface (3b) are used to attach the seat Fixed through.

Therefore, the pair of left and right groove cutting blades (7), (8) are staggered forward and backward with respect to the traveling direction indicated by the arrow F of the foamed resin plate (1) as shown in FIGS. Attaching the groove cutting blades (7) and (8) at the disagreement is a conventional means for reducing the groove cutting resistance.

Reference numeral (10) is a chip removing member, which is bent to have a V-shaped cross section, and a ridgeline (10a) of the bend is formed in a substantially arc shape, and the ridgeline (10a) has a length of about 1 / l. 2 has a thinned portion (10b) with the thickness cut off from both sides to make the tip thin so that it can be easily inserted into the cut V groove. As shown in FIG. 4, the end of the ridge line (10a) on the side of the carved portion (10b) is covered with the chip removing member mounting portion (4) so as to approach the rear of the groove cutting blade (6) and the mounting screw (11) is attached. It is installed by.

Reference numeral (12) is a foamed resin plate support, and a steel wire is laid above the grooving body (3) between the two grooving blades (7) and (8) in the front-rear direction to groov the steel wire. The foamed resin plate (1) comes into contact with the lower surface (back surface) of the foamed resin plate (1) to support the foamed resin plate (1), and the front (3a) side of the grooved body (3) is bent downward to the front (3a). It is fitted in a foamed resin plate support mounting groove (13) provided in the upper and lower direction at the center of the width direction of the and is fixed by means of a cap screw (14) via a seat.

A pressing roll (15) is located above the two groove cutting blades (7) and (8) and is in contact with the upper surface (surface) of the foamed resin plate (1) to support the foamed resin plate support ( 12), which prevents the foamed resin plate (1) from rising due to grooving resistance.

(16) is a mounting long hole, which penetrates from the front side (3 a) to the back side in the center of the lower portion of the groove cutting body (3) in the width direction, for mounting on a part of the machine (not shown) belongs to.

In the grooved device for foamed resin having the above structure, the grooved blades (7), (8) are provided on the back side of the foamed resin plate (1) with the surface facing upward as shown in FIG. (1). The V groove (1a) is formed by placing the foamed resin plate (1) in the direction of the arrow F with the feed roll (2) at a position where a V groove having a predetermined depth is cut, and a string-shaped chip ( 1b) forcibly separates the flat surface portion (S) by the chip removing member (10) and prevents attachment due to static electricity, and the G arrow along the ridgeline (10a) of the chip removing member (10). It is guided in the direction and is removed by a chip reservoir (not shown).

[0020]

[Effect of device]

 According to the V-grooving device for a foamed resin plate according to the present invention, since the chip removing member is provided behind the groove cutting blade, the string-shaped chips are reliably removed from the V groove, and the inside of the V groove is surely removed. Since it does not remain in the chip removing work, there is no need for post-processing chip removal work.In addition, the chips are reliably guided to the chip reservoir along the inside of the ridge of the chip removing member and pinched by other moving parts. It can be resolved.
