Description

  The present invention provides a folder gluer which forms a flat box by folding and bonding panels on both sides while conveying a blank made of corrugated cardboard sheets having four panels divided by vertical ruled lines in one direction. It is about.

As a blank made of a corrugated cardboard sheet for forming a box, the one shown in FIG. 6 is known. The blank B includes first panels P _{1 to} P ₄ divided by first vertical ruled lines a _{1 to} fourth vertical ruled lines a ₄ , and joining margins P ₅ , and includes first panels P _{1 to} P _1. A lid flap F ₁ is connected to _one end edge of the fourth panel P ₄ via a horizontal ruled line b ₁ , and a bottom flap F ₂ is connected to the other end edge via a horizontal ruled line b _2. Yes.

The blank B as described above is supplied to the folder gluer, and the first panel P ₁ and the fourth panel P ₄ on both sides are bent by 180 ° by the folder gluer, and the joining margin P ₅ and the first panel P ₁ are connected. A flat box A as shown in FIG. 7 is formed by bonding to each other.

The flat box A is opened in a rectangular cylinder, the bottom is formed by folding the bottom flap F ₂ , and the lid is formed by folding the lid flap F ₁ to form a packaging box. Before the lid flap F ₁ is folded, the product is packed inside.

Here, the blank B forming the packaging box is subjected to the first vertical ruled line a _{1 to} the fourth vertical ruled line a ₄ and the horizontal ruled lines b ₁ and b _{2 on} a rectangular cardboard sheet, and the first vertical ruled line a _{1 is formed.} to be formed by performing punching for grooving the respective both ends of the third vertical lines a _3, paper dust generated during the punching. Further, at the time of punching, the corrugated cardboard sheet is crushed, and punching is performed in a state where the corrugated center provided between the front and back liners is deformed into an S-shape, so that whisker-like punching waste is generated at the punching and cutting portion. There are many cases.

  If the above paper dust or punched waste (hereinafter collectively referred to as “paper dust”) adheres to the blank B and remains on the product packaged by the packaging box, the product value is lowered. In particular, when the product is a food, the paper powder gives an unsanitary feeling, and the value of the product is significantly reduced.

  In order to solve such a problem, paper dust adhering to a flat box is removed before the packaging box is formed.

  As a method for removing paper dust adhering to a flat box, a method for removing by suction and a method for removing it by contact with a brush are conventionally known.

  Here, when removing paper dust by suction, paper dust collection efficiency is low, and therefore, paper dust is removed by contact with a brush.

  By the way, in the conventional paper dust removing device that removes paper dust by contact with the brush, a set number of flat boxes discharged from the folder gluer are stacked and bundled, and the outer circumference of the bundled flat boxes is bundled. Since the paper dust is removed by contacting the brush that is driven to rotate, only the paper dust adhering to the outer periphery of the flat box can be removed, and the outer periphery of the abutting surface of the flat box The paper dust adhering to the part cannot be removed, and there remains a disadvantage that a flat box body with low paper dust removal efficiency and low paper dust adhesion cannot be obtained.

  An object of the present invention is to provide a folder gluer that can form a good flat box with very little adhesion of paper dust.

  In order to solve the above problems, in the present invention, a blank made of a corrugated cardboard sheet having four panels divided by vertical ruled lines is conveyed in one direction, and the panels on both sides are rotated in the same direction during the conveyance. In a folder gluer that forms a flat box by bending and joining the joint margin continuously provided on the side edge of one side panel and the overlapping part of the other side panel, the panels on both sides of the blank are A suction cover that has openings on both sides of the 180 ° folded position and a suction force inside is provided so that the opening faces the bent portions on both sides of the blank, In this suction cover, a configuration is adopted in which brush rolls that are rotationally driven in contact with both side edges of the blank are provided.

  As described above, by providing a brush roll that rotates in a state in which the panels on both sides of the blank are bent by approximately 180 ° in contact with both side edges of the blank, both sides of the blank are brought into contact with the brush roll. Since the paper dust adhering to the part can be removed and the blanks are processed one by one continuously, the contact between the brush roll and the blank is good, and the paper dust adhering to both side edges of the blank is extremely It can be effectively removed, and a good box with very little adhesion of paper dust can be obtained.

  Further, since the removed paper dust can be sucked into the suction cover, it is possible to prevent the paper dust from being scattered around and to prevent the working environment from deteriorating.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the folder gluer has a lower conveying belt 2 shorter than the upper conveying belt 1 below the two upper conveying belts 1 arranged substantially in parallel, and a carry-in end at the upper side. The punching and ruling shown in FIG. 6 is provided with a carrier-side belt 1a below the upper conveyor belt 1 and a carrier-side belt 2a located above the lower conveyor belt 2 so as to substantially coincide with the carry-in end of the conveyor belt 1. The blank B, which has been subjected to insertion processing, is gripped from above and below and conveyed in the direction of the arrow in FIG. 1, and the first panels P _{1 on} both sides of the blank B are provided by first folding bars 3 provided on both sides of the conveyance path. The fourth panel P ₄ is bent downward along the first vertical ruled line a ₁ and the third vertical ruled line a ₃ inside thereof.

Although omitted in the figure, folding guides are provided on the outer side of the lower conveyor belt 2 corresponding to the first vertical ruled lines a ₁ and third vertical ruled lines a ₃ of the blank B, and along the bent guides. Thus, the first panel P ₁ and the fourth panel P ₄ are further bent downward.

The bending guide (not shown) is configured so that the first panel P ₁ and the fourth panel P ₄ gradually move from the position where the blank B is horizontally supported to the second panel P ₂ and the third panel P ₃ by about 90 °. It has a length that reaches the position where it can be bent.

In addition, one end of a folding belt 4 for panel folding is disposed on each outer side of the carry-out end of each lower conveying belt 2, and the carrier side belt 4a of the folding belt 4 is connected to a plurality of belt guide rollers. 5, torsion is applied and the other end of the carrier side belt 4 a is vertically opposed to the carry-out end of the carrier side belt 1 a in the upper conveyance belt 1, and the carrier side belt of each of the folding belts 4. The first panel P ₁ and the fourth panel P ₄ of the blank B are further bent inward by 90 ° by 4a and the second folding rod 6 provided along the carry-out end of each carrier side belt 4a. To be horizontal.

Furthermore, a plurality of grooved forming rolls 7 are provided on both sides of the conveyance path of the blank B, in which the first panel P ₁ and the fourth panel P _{4 are} bent by approximately 180 °, and spaced apart in the conveyance direction of the blank B. The bent portions on both sides of the blank B are formed by the attached forming roll 7 and the first panel P ₁ and the fourth panel P ₄ of the blank B are held in a 180 ° folded state to form the fourth panel P ₄ . The joining margin P ₅ provided continuously and the side edge portion of the first panel P ₁ that overlaps the joining margin P ₅ are joined to each other via the adhesive previously applied to the joining margin P ₅ , and a flat box A is formed. Try to form.
