Description

Counter ejector for a box cutter and ejection method using the same

[0001] The present invention relates to a counter ejector for a box forming machine, and more specifically, to a counter ejector for a box forming machine capable of counting folded box cardboard in a predetermined number and stacking and aligning them before ejecting them, and an ejection method using the same, in a box forming machine for manufacturing boxes.

[0002] In general, a corrugated cardboard machine is a device that mainly manufactures packaging boxes, boxes, etc. using corrugated cardboard. It folds sheets of corrugated cardboard manufactured by a separate device, applies glue to them, makes several sheets into bundles, and then uses these to manufacture each sheet into a box, etc.

[0003] This box-making machine is composed of a feeding device that supplies sheets of overlapping corrugated cardboard individually, a printing device that prints on each sheet fed, a creaser slotter device that draws lines on each printed sheet, cuts grooves, and forms a seam, a folding gluer device that folds and joins along the lines while supplying and applying glue to the seam, and a counter ejector that counts a set number of folded box sheets, stacks and aligns them, and then discharges and transports them.

[0004] As disclosed in Korean Patent Publication No. 29277, 2010 (published on March 16, 2010), a conventional counter ejector for a box forming machine has a technology developed that comprises a register that moves toward the inside of the hopper to receive boxes in the hopper when the number of boxes accumulated in the hopper reaches a predetermined number, a press bar that is formed to be able to move up and down relative to the register and pressurizes a batch on an elevator by moving downward relative to the register, and an elevator that is formed to be able to ascend and descend below the hopper and ascend to receive boxes accumulated in the hopper and descend to place the batch of boxes on a lower conveyor, thereby accumulating and discharging a predetermined number of folded boxes.

[0005] In addition, as disclosed in Korean Patent Publication No. 2013-86229 (published on July 31, 2013) or Korean Patent Publication No. 2018-16548 (published on February 14, 2018), the main ledge and the press bar that rises and falls from the ledge are commonly configured on the upper side of the hopper, in which an auxiliary ledge is installed to open and close horizontally at the bottom, and the auxiliary ledge supports the boxes supplied from the bottom of the hopper so that several boxes are stacked, and after being aligned by the hopper, the press bar presses downward on the upper part of the elevator so that the stacked boxes are lowered and then placed on the lower conveyor to be discharged. At this time, in order for the supply of folded boxes to not stop and to be continuously supplied, the upper ledge supports instead of the auxiliary ledge at the bottom of the hopper, and then as it falls forward from the hopper, the boxes partially stacked are delivered to the auxiliary ledge, and after counting a predetermined number, the ledge is put back into the hopper, and the stacked boxes are pressed by the press bar that is also put in. Therefore, conventional counter ejectors such as this have a register, which occupies the largest part of the device, and a press bar that rises and falls to pressurize the upper part of the boxes stacked on the register, and are inserted into the hopper, and then move forward while the press bar is lowered, and then the press bar rises again, and the register and press bar as a whole rise and then move backward to the upper part of the hopper, so the volume of the counter ejector increases and its structure becomes complicated, and the operation of the counter ejector to stack, align, and eject boxes becomes cumbersome, so it takes a lot of time to eject, and so on, and there are many problems.

[0029] The present invention provides a counter ejector for a box making machine and an ejection method using the same, which can count folded box cardboards in a predetermined number and stack and align them for ejection in a box making machine for manufacturing boxes. The present invention will be described in more detail below with reference to the drawings. However, the attached drawings are only examples for easily explaining the content and scope of the technical idea of ​​the present invention and are not limited thereto. The terms used are also only for specifically explaining embodiments and should not be interpreted as being limited to the terms.

[0030] In the counter ejector (1) for a box forming machine of the present invention and the ejection method using the same, the counter ejector (1) for a box forming machine of the present invention is configured so that boxes (B) supplied from a supply roller (2) are aligned and stacked in a stacking hopper (4), as shown in FIGS. 1 and 2 to 12, and an opening / closing means (5) and an elevation / transport means (6) and a discharge / transport means (7) are provided at the bottom of the stacking hopper (4) for transporting the stacked boxes (Bp1, Bp2) when opened, and a stacking guidance means (8) is provided for smoothly guiding the alignment and stacking of boxes (B) supplied from the front upper side of the stacking hopper (4) and boxes (Bp1, Bp2) stacked by descending from the upper part of the stacking hopper (4) to the lower part.

[0031] The configuration of the present invention will be described in detail as shown in Fig. 1.

[0032] The above supply roller (2) is configured to individually supply folded boxes (B) discharged from a folding gluer device that supplies and prints in a sheet state, applies glue to the seam portion of a corrugated cardboard sheet that has formed a line and groove, and folds along the line, toward the front horizontally.

[0033] A blocking plate (3) having a cushioning force is installed in front of the above-mentioned supply roller (2). This blocking plate (3) is positioned in front of the supply roller (2) so that the boxes (B) supplied individually by the supply roller (2) are blocked in front without damage and fall downwards. Since it has a cushioning force, damage to the supplied boxes (B) can be minimized.

[0034] The above-mentioned stacking hopper (4) is located in front of the supply roller (2) so that the supply box (B) blocked by the blocking plate (3) can be dropped and arranged and stacked in order.

[0035] Among the components installed at the bottom of the above-mentioned stacking hopper (4), the opening and closing means (5) is installed to be horizontally introduced and withdrawn into and out of the bottom of the stacking hopper (4) so ​​that the bottom of the stacking hopper (4) is closed and opened so that when the box (B) is introduced and closed, the box (B) is placed and placed, and when the box is withdrawn and opened, the placed boxes (Bp1, Bp2) are discharged downward from the stacking hopper (4), and when the stacking guidance means (8) is transported downward together with the lifting and lowering means (6) and then transported upward from the front, the opening and closing means (5) at the front and rear lower portions of the stacking hopper (4) are installed to be horizontally introduced and withdrawn into and out of the stacking hopper (4) by the respective horizontal driving means (51), and the vertical transport plate (52) is transported downward by the vertical driving means (53) composed of a cylinder and a piston rod or a solenoid valve and a core or a driving motor and a driving gear and a driven gear, respectively, to remove some of the placed boxes (B). It is configured to increase the number of boxes (B) stacked inside the stacking hopper (4) while the stacking guidance means (8) is introduced between the blocking plates (3) by being transported downward from the inside of the stacking hopper (4).

[0036] In this way, the opening / closing means (5) is configured to open and close the lower part of the loading hopper (4) by being introduced into and withdrawn from the loading hopper (4) by a horizontal driving means (51) similar to some of the conventional technologies, and is configured to be installed on a vertical transport plate (52) and to vertically raise and lower the vertical transport plate (52) by a vertical driving means (53) to be differentiated from the conventional technologies.

[0037] And the lifting and transporting means (6) located at the bottom of the above-mentioned stacking hopper (4) is installed to be lifted from the bottom of the stacking hopper (4) so ​​that when the lower part of the stacking hopper (4) is opened by the opening and closing means (5), the stacked boxes (Bp1, Bp2) are placed therein and transported downward, and the discharge and transporting means (7) is configured as a conveyor so that the stacked boxes (Bp1, Bp2) transported downward from the stacking hopper (4) by the lifting and transporting means (6) are placed therein and transported forward.

[0038] In the present invention, the stacking guidance means (8) is configured to simplify the ledge, which is a shelf for receiving boxes supplied in the prior art, and the press bar, which presses the stacked boxes downward, into a single component, while eliminating the drive device of the press bar and the like, and to operate in a different order from the elevating opening / closing means (5).

[0039] Such a stacking guidance means (8) is fed into the stacking hopper (4) between the front blocking plates (3) and is raised and lowered so that when a set number of boxes (B) are counted and placed in the stacking hopper (4), the boxes (B) supplied to the upper portion are placed. When the boxes (Bp1, Bp2) placed inside the stacking hopper (4) are placed on the lifting transport means (6), the upper portions of the placed boxes (Bp1, Bp2) are pressed downwards so that the boxes (Bp1, Bp2) placed on the lifting transport means (6) are fixed and pressurized. When the lifting transport means (6) is transported downward, the placed boxes (Bp1, Bp2) are lowered together in a pressurized state so that the placed boxes (Bp1, Bp2) are maintained in an aligned state, and the boxes (B) placed on the upper portion are closed inside the stacking hopper (4). It is configured to be transmitted to the opening / closing means (5), and while a set number of boxes (Bp1, Bp2) are supplied inside the storage hopper (4), they rise from the front and then flow into the inside of the storage hopper (4) between the blocking plates (3).

[0040] The ejection method using the counter ejector (1) for the present invention configured as described above is performed by counting the entire number of ejectors using the counter ejector (1) of the present invention as shown in FIGS. 2 to 12, and this will be described in more detail step by step.

[0041] 1. Counting supply stage (S1)

[0042] In the present invention, a folded box (B) discharged from a folding gluer device that applies glue to the seam portion of a corrugated cardboard sheet that is supplied in a sheet state as shown in FIG. 2 and has a line and groove formed therein and is joined along the line while being printed, is counted individually by a supply roller (2) and continuously supplied forward.

[0043] 2. Hopper stacking stage (S2)

[0044] As shown in Fig. 2, the individual boxes (B) supplied in the counting supply step (S1) are blocked by the blocking plate (3) and fall into the inside of the stacking hopper (4) so ​​that they are aligned and stacked and stacked on the closed opening / closing means (5) at the bottom.

[0045] 3. Hopper discharge stage (S3)

[0046] And as shown in Fig. 3, when a predetermined number of boxes (Bp1) (=8 in the drawing) are aligned and stacked inside the stacking hopper (4) in the hopper stacking step (S2), the opening / closing means (5) is opened and the boxes (Bp1) are placed on the top of the elevated transport means (6), and the top of the stacked boxes (Bp1) is pressurized by the stacking guidance means (8).

[0047] 4. Storage compartment stage (S4)

[0048] In the above hopper discharge step (S3), when the upper part of the stacked box (Bp1) is pressurized by the stacking guidance means (8), the box (B) continuously supplied by the counting supply step (S1) to the upper part of the stacking guidance means (8) is blocked by the blocking plate (3) and falls and is placed, and several boxes are stacked, and in this way, the box (B) continuously supplied by the supply roller (2) is divided into the stacked box (Bp1) inside the stacking hopper (4) which is pressed downward by the stacking guidance means (8) and the box (B) which is supplied upward by the stacking guidance means (8) and begins to be aligned and stacked, and the stacking guidance means (8) plays the role of a conventional press bar that pressurizes the box (Bp1) stacked downward and simultaneously plays the role of a ledge that supports the box continuously supplied upward and divides it into upper and lower parts, and as a result, the action is reduced, and the work process and the configuration of the device are simplified. In order for the operation to be performed continuously with this advantage, a lowering step (S7-1) in which the opening / closing means (5) is lowered along with the transfer step (S7) described below is required, and thereby a returning step (S5-2-1) in which the opening / closing means (5) is raised is required.

[0049] 5. Descending transfer stage (S5)

[0050] As shown in Fig. 4, in the hopper discharge step (S3), the material is transferred from the loading hopper (4) to the lifting and transporting means (6) and lowered together with the lifting and transporting means (6) supported at the bottom and the loading guidance means (8) pressurized at the top.

[0051] 6. Partial delivery stage (S6)

[0052] At this time, when the lifting and lowering means (6) and the stacking guidance means (8) descend in the above-mentioned downward transport step (S5), the upper part of the stacking hopper (4) is closed by the opening and closing means (5) when the upper part of the stacked box (Bp1) passes by, and the box (B) placed or partially placed on the upper part of the stacking guidance means (8) in the stacking compartment step (S4) is transferred to the opening and closing means (5) as shown in Fig. 5, and after being placed and placed, the box (B) continuously supplied from the supply roller (2) is sequentially aligned and placed on the upper part.

[0053] 7. Transfer stage (S7)

[0054] Thereafter, in the present invention, as shown in Fig. 6, the box (Bp1) placed by the lower lifting transport means (6) and the upper loading guidance means (8) through the lowering transport step (S5) is transferred so that it is stably placed on the upper rear of the discharge transport means (7) formed of a conveyor without being disturbed.

[0055] 7-1. Lowering stage of opening / closing means (S7-1) (= lowering action of opening / closing means (5))

[0056] At this time, as seen in FIG. 6, in the present invention, the opening / closing means (5) installed to open / close at the bottom of the stacking hopper (4) is configured to be raised / lowered, and as the opening / closing means (5) at the bottom of the stacking hopper (4) is lowered to a lower position without leaving the stacking hopper (4) through the above-mentioned transfer step (S7), the supply of boxes (B) is continuously provided to the upper portion of the stacking hopper (4), so that a greater number of boxes (Bp2) can be stacked on the stacking hopper (4) than in the hopper stacking step (S2).

[0057] 8. Discharge transfer stage (S8)

[0058] As shown in Fig. 7, in the above-described transfer step (S7), the box (Bp1) placed is transferred to the forward position by the discharge transfer means (7) in which the box (Bp1) is placed.

[0059] 9. Induction cycle stage (S9)

[0060] In the above discharge transfer step (S8), the stacking guidance means (8) that is transferred forward and then transferred upward together with the stacked box (Bp1) that is transferred forward is introduced between the blocking plates (3) so that the stacking guidance means (8) that is positioned so as not to interfere with the supply of the box (B) to the upper portion of the stacking hopper (4) is circulated to the original position, and accordingly, as shown in FIG. 7, the stacking guidance means (8) is circulated to the upper portion of the stacking hopper (4) as in the counting supply step (S1) and the hopper stacking step (S2) of FIG. 2, but the opening / closing means (5) is supplied to the stacking hopper (4) in the lowered position so that the stacked box (Bp1) is supported and closed at the lower portion of the stacking hopper (4).

[0061] 10. Elevator return stage (S10)

[0062] At this time, as in FIG. 7, the lifting and transporting means (6) is raised together with the above-mentioned induction means circulation step (S9) to be positioned below the opening and closing means (5) at the bottom of the stacking hopper (4), but since the opening and closing means (5) is closed at the lowered position of the stacking hopper (4), the upper part of the lifting and transporting means (6) detects the opening and closing means (5) so that the lifting and transporting means (6) does not rise to the position of the raised opening and closing means (5) as in the hopper stacking step (S2) of FIG. 2, but only rises to the position of the lowered opening and closing means (5) by the opening and closing means lowering step (S7-1).

[0063] 11. Secondary Hopper Stacking Stage (S2-2)

[0064] In Fig. 7, the stacking guidance means (8) and the lifting and transporting means (6) are circulated and returned to their original positions, and the individual boxes (B) supplied in the counting supply step (S1) are blocked by the blocking plate (3) by the opening and closing means (5) lowered in the opening and closing means lowering step (S7-1) and fall into the inside of the stacking hopper (4) to be aligned and stacked, and are stacked on the closed opening and closing means (5) at the bottom.

[0075] 16. Secondary transmission stage (S7-2)

[0076] As shown in Fig. 11, the box (Bp2) stacked by the lower lifting transport means (6) and the upper loading guidance means (8) through the second lowering transport step (S5-2) is transferred to the upper rear of the discharge transport means (7) formed of a conveyor without being disturbed.

[0077] 17. Secondary Emission Transport Stage (S8-2)

[0078] In the present invention, as shown in Fig. 12, the box (Bp2) placed in the secondary transport step (S7-2) is transported forward by the discharge transport means (7) in which the box (Bp2) placed is placed.

[0079] 18. Secondary Induction Means Circulation Stage (S9-2)

[0080] In Fig. 12, the stacking guidance means (8) that is moved forward and then moved upward together with the stacked box (Bp2) that is moved forward in the secondary discharge transfer step (S8-2) is introduced between the blocking plates (3) so that the stacking guidance means (8) that is positioned so as not to interfere with the supply of the box (B) to the upper portion of the stacking hopper (4) is circulated to the original position, and according to this, as in Fig. 2, the stacking guidance means (8) is circulated to the upper portion of the stacking hopper (4) as in the counting supply step (S1) and the hopper stacking step (S2), but the opening / closing means (5) is closed at the lower portion of the stacking hopper (4) so ​​that the stacked box (Bp2) is supported by being supplied to the stacking hopper (4) in the lowered position.

[0081] 19. Second lift return stage (S10-2)

[0082] In FIG. 12, together with the secondary induction means circulation step (S9-2), the lifting and transporting means (6) is raised to be positioned below the opening and closing means (5) at the bottom of the stacking hopper (4), and a sensor or the like capable of detecting the opening and closing means (5) is provided on the upper side of the lifting and transporting means (6), so that when the opening and closing means (5) is raised as in FIG. 2 and positioned at a certain height from the bottom of the stacking hopper (4), the lifting and transporting means (6) is also raised to a position just below it, and when the opening and closing means (5) is lowered as in FIG. 7 or FIG. 12 and positioned at the bottom of the stacking hopper (4), the lifting and transporting means (6) is also raised to a position just below the opening and closing means (5) located below it.

[0083] In the present invention, when the above steps are continuously repeated, from the first cycle, the counting-counting supply step (S1) to the lifting means return step (S10), the boxes (Bp1) stacked in a predetermined quantity of 8 as shown in the drawing are aligned and stacked during the counting supply and then discharged and transported, and from the next process, the second hopper stacking step (S2-2) to the second lifting means return step, the boxes (Bp2) stacked in a quantity greater than the predetermined quantity of 11 as shown in the drawing are aligned and stacked during the counting supply and then discharged and transported, and from the subsequent processes, as the opening and closing means (5) is raised and lowered, the boxes (Bp2) stacked in a quantity greater than the predetermined quantity of 11 as shown in the drawing inside the stacking hopper (4) are aligned and stacked during the counting supply and then discharged and transported, which allows additional boxes (B) to be stacked by the opening and closing means lowering step (S7-1) in which the opening and closing means (5) is lowered. The opening / closing means (5) rises through the opening / closing means return step (S5-2-1) and then descends again to additionally supply boxes (B), thereby enabling a larger quantity of stacked boxes (Bp2) to be discharged and transported, thereby significantly improving the efficiency of counting ejection, and thereby enabling a larger amount of boxes (B) to be discharged compared to the prior art. In addition, the stacking guidance means (8) simplifies the configuration of the ledge and the press bar into one device in the prior art, thereby simplifying the operation, and thereby significantly reducing the manufacturing cost and the maintenance and repair costs.
