Abstract

PURPOSE:To prevent that blanks are mutually damaged by a cutting blade by taking out the blank from a film cutting blade fixing position one at a time at each time when a film cutting blade is fixed to the predetermined place of the blank of a carton for receiving a film winder to feed the same to a sack bonding box making machine. CONSTITUTION:A stopper 16 rises and a blank 1 having a cutting blade 7 mounted thereto is drawn near toward the second conveyor 19 by driving the first conveyor 12 and a nip roller 20. The second conveyor 19 discharges said blank 1 toward the third conveyor 21 which in turn alters the direction of the blank by about 90 deg. to feed the blank to the next sack bonding box making machine. Therefore, the blank 1 is taken out one at a time from a cutting blade fixing position by the second conveyor 19 at each time when the film cutting blade is fixed to the predetermined place of the blank 1 and fed to the sack bonding box making machine by the third conveyor 21. Therefore, the blank issued from a cutting blade mounting machine is prevented from overlapping with the other blank.

Further, reference numeral 18 indicates a labeler for pasting the seal 5 on the blank 1 temporarily stopped within the mold section 13.

A second conveyor 19 is installed at the location where the blank 1 leaves the first conveyor 12.

Moreover, at the starting end of one of the second conveyors, a mold part 13 is provided.
A nip roller 20 is provided for drawing out the blank 1 to which the cutting blade 7 is fixed.

Further, a third conveyor 21 is provided at the terminal end of the second conveyor 19 and extends in a direction perpendicular thereto.

In addition, what is indicated by the reference numeral 22 is the second conveyor 19.
This is a stopper for stopping the blank 1 discharged from the blank onto the third conveyor 21.

To explain the movement of the machine when installing the cutting blade with the above configuration,
First, the feeder 11 feeds the blank 1 into its loading section 1.
Blanks 1 are taken out one by one onto a first conveyor 12 from 0, and the first conveyor 12 intermittently feeds the blanks 1 one by one into a mold section 13. At this time, the stopper 16 is lowered, and the blank 1 is stopped at an appropriate position within the mold section 13.

Next, the labeler 18 operates to affix the seal 5 to a predetermined location, and the punch 13a of the mold section 13 rises to punch out the thin metal plate 15 and press it to form the cutting blade 7, and at the same time stamps the blank 1 into the blank 1. Attach.

Thereafter, the stopper 16 is raised, and the blank 1 to which the cutting blade 7 is attached is pulled out toward the second conveyor 19 by driving the first conveyor 12 and the nip roller 20. The second conveyor 19 discharges the blank 1 toward the third conveyor 21, and the third conveyor 21 changes the direction of the blank 1 by approximately 90 degrees and conveys it toward the next sack pasting box machine. do.

Therefore, as shown in FIG. 1, each time the film cutting blade 7 is fixed to a predetermined location, the blank 1 is taken out one by one from the cutting blade fixed position by the second conveyor (step I ), and is transported by the third conveyor 21 to the sack pasting box machine (Step 2).

Therefore, when attaching the cutting blade, the blank that comes out of the machine does not overlap with other blanks.

The sack pasting box forming machine shown in FIGS. 3 and 4 performs the process opening to (1).

In the illustrated example, the sack pasting box making machine includes a sorting section 23 for sorting the blanks 1 into good and defective products, and receives and receives good blanks that come out one by one from the sorting section 23, and inverts the blanks to expose the back side of the blanks. a reversing part 24 for turning upward (step ■);

The sorting section 23 includes a conveyor belt 28 continuous to the third conveyor 21, and a rotating plate 29 at the starting end of the conveyor belt 28. The rotary plate 29 is rotated between the frame 32 and the inside of the conveyor belt 28 with the start end of the conveyor belt 28 as a fulcrum by a link machine 1R31 using a solenoid 30 as a driving source. It is designed to move. In addition, the rotating plate 29
A roller 33 is installed slightly above the rotary plate 29 to clamp the blank 1 together when the rotary plate 29 rotates upward.

For this reason, the sensor 34 on the conveyor 21 detects, for example, a blank in which the cutting blade 7 is installed in an abnormal position. 32.

Then, only the non-defective blanks are conveyed to the next reversing section 24 by the conveyor belt 28.

The reversing section 24 includes two sets of conveyors that are twisted and arranged between the sorting section 23 and the next gluing section 25 along the flow direction of the blanks 1.

The conveyor on the upstream side includes two endless belts 35 facing each other, and each endless belt 35 has two rollers 36 arranged horizontally opposite to each other near the end of the conveyor belt 28 of the sorting section 23 and a reversing section. They are stretched between two rollers 37 that are vertically opposed to each other at the center. Moreover, a plurality of rollers 38 are installed between the horizontal roller 36 and the vertical roller 37 so that the inclination gradually changes from horizontal to vertical.

The downstream conveyor includes two endless belts 39 stretched between the center of the reversing section and the starting end of the gluing section 25, and the endless belts 39 are continuous in the twisting direction of the upstream conveyor. As shown in FIG.

Incidentally, reference numeral 43 indicates a motor with a speed reducer which is a driving source of the conveyor of this reversing section 24.

In this reversing section 24, the blank 1 coming from the sorting section 23 is turned over (step III), and the cutting blade 7 r)
-It will be discharged with the back side facing up.

The gluing section 725 includes two upper and lower endless belts 44a and 44b that run adjacent to each other, and the endless belts 44a,
A glue wheel 45 is provided at a position where it can come into contact with the bent piece 3 of the blank 1 protruding from between 44b.

A fixed amount of adhesive is supplied to the glue wheel 45 from an adhesive tank 46. Note that the glue wheel 45 is rotated by obtaining power from a motor 47 with a reduction gear via a line shaft 48 or the like.

This gluing is carried out in the section 25 by the endless belt 44a.

44b, the bent piece 3 of the blank 1 runs between
Adhesive is applied in stripes.

The endless belts 44a, 44b reach a folding portion 26, and the folding portion 26 is provided with a guide member 49 for folding the bent piece 3 of the blank 1 along the fold line.

A large number of bank up rollers 50 are disposed at the contact points between the upper and lower endless belts 44a and 44b so that the direction of the blank 1 will not shift due to the resistance received from the glue wheel 45 and the guide member 49.

Similarly to the bending section 26, the pressing section 27 also has an upper and lower endless belt 51. a, 51b, and other upper and lower endless belts 5 disposed on the extension line of those endless belts.
2a and 52b.

These endless belts 51a, 51b, 52a.

52b is driven by the power of the motor 47. Also, as with the endless belt of the folded portion 26, pressure is applied from behind by a backup roller 50.

Step (2) is completed in this pressurizing section 27, and the blank 1 is discharged from the sack pasting box forming machine. In this step (3), the folded piece 3 is pressure-bonded to the body wall 2e adjacent to it, so that the folded piece 3 has the function of reinforcing the edge of the body wall 2e when the package is opened as described later. do.

The blank 1 is then processed by another part of the sack pasting box machine (not shown), and is discharged in the form of a flat cylinder through steps v and (2).

In this state, the five body walls 2 that make up the body of the blank are
Body walls 2a, 2 on both sides among a, 2b, 2c, 2d, 2e
e are superimposed.

After that, the folded blank is made into a three-dimensional rectangular tube shape, a film roll (not shown) is loaded therein, and the body walls 2a and 2c at both ends are bonded to each other at the circular notch 6. Then, the end wall 4 is closed and the carton containing the contents is shipped.

In order to use such a product, the package is opened by cutting off a portion of the body wall 2a outside the cutting line 8. The opening is
This can be easily done since the circular cut portion 6 causes delamination.

Then, by pulling out the end of the film of the roll by a predetermined length from the unsealing part and pulling it against the serrated cutting blade 7 exposed along the cutting line 8, it can be easily cut.

[Operation and effect of the invention]

As described above, each time a film cutting blade is fixed to a predetermined position of a blank of a carton for storing a film roll body, the blanks are taken out one by one by a conveyor from the position where the film cutting blade is fixed and placed in a sack pasting box. Since this method is characterized by being transported toward the shore, there is no need to pack the blanks with the cutting blades attached into boxes and then transport the boxes to the sack pasting and boxing machine. Furthermore, when assembling blanks, there is no need to take out a stack of blanks from a box and load them into a feeder.

Therefore, the blanks are prevented from coming into contact with each other after the cutting blade is attached, and it is possible to completely prevent the blanks from being damaged by the cutting blade.

Moreover, this has the effect that the application of varnish to the printing surface, which is conventionally required, can be reduced or omitted.
