[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an apparatus for removing excess portions of paperboard for packaging containers, which removes the excess portions around the paperboard for packaging containers with high efficiency. be.

Ω- (Prior art) When making a paper packaging container from a flat paperboard such as corrugated paper or cardboard, a press or the like is used to cut the outer circumferential cut line such as a perforation on a quadrilateral paperboard, and a fold line inside the cut line. and form
Remove the excess portion outside the cutting line, bend the fold line, and assemble the bottom and sides - fasten with adhesive or staples. When pressing paperboard to form cut lines or fold lines, the cut lines must not coincide with the edges of the paperboard. Therefore, on the four sides of the paperboard, there will be excess portions extending outside the cutting line.

In the past, this surplus part was manually removed one by one,
Paperboard is stacked and removed using a power tool with a rotating claw at the tip.

(Problem to be Solved by the Invention) However, manually removing the excess portion of paperboard is extremely inefficient, and it is impossible to remove a large number of sheets of paperboard even if it takes a long time.

Further, even if a power tool is used, the four sides of the stacked paperboard must be removed individually, and while removing the negative side, the inside of the cutting line may be damaged.

(Means for solving the problem) The present invention has been proposed in view of the above, and includes a plurality of actuation mechanisms each having a claw member at the tip on the table surface of a base that can be raised and lowered as a support. The claw members of the actuating member are adjustable in the horizontal direction along the length of the table surface, the vertical direction, and the front-rear direction, and the claw members of each of the above-mentioned operating mechanisms are made to face the side edge of the paperboard stack. The present invention provides an apparatus for removing surplus portions of paperboard for packaging containers, which is characterized in that surplus portions on four sides of the paperboard are simultaneously removed.

(Function) According to the present invention, by simply lowering the base onto the paperboard laminate, the excess portions on the four sides of the paperboard can be removed at the same time.
Can be removed quickly.

(Example) The present invention will be explained below with reference to embodiments of the drawings.

/ is a frame consisting of a bottom part, pillars 3 standing upright at the four corners of the bottom part, and an upper part provided at the upper end of the pillars 3, and a paperboard laminate α is placed inside this frame /. Entry and exit is possible on the left side of the running trolley.

A cutting line C, such as a perforation, is located near the outer peripheral edge of the paperboard laminate α, and the area outside this cutting line is an excess portion d, which must be removed before being assembled into a paper packaging container.

The above-mentioned upper part is equipped with an oil or air cylinder, and when this cylinder is operated, the paperboard laminate α is
A press plate t, 1 that presses the frame from above is positioned above the inside of the frame. Then, male screw rods are attached to the inside of the pillars 3 at the four corners of the frame, and a driving mechanism for each male screw rod 7 is provided on the upper surface of the upper part. This drive mechanism g consists of a motor drive capable of forward and reverse rotation, a first rotation transmission mechanism l/ on the low speed side and a second rotation transmission mechanism l/ on the high speed side, which transmit the rotation of the motor drive to the gear box lO, and a gear box 1
0 is hung on the wheel 13 provided at the top of each male threaded rod 7. Pass the drive chain 17 in series, and hang the tension wheel /1 in the middle of this drive chain /7.

There is an electric clutch (not shown) b'' inside the gear box 10, and the rotation of the motor 9 is transferred to the first rotation transmission mechanism.
The rotation transmission mechanism D is transmitted to the gear box 10 by the second rotation transmission mechanism D, and the drive of one of the rotation transmission mechanisms D is transmitted to each male threaded rod 7 via the chain L by the operation of the electric clutch. In this case, if the rotation of the motor 9 is transmitted to each male screw lever by the first rotation transmission mechanism /, the rotation of the motor 9 is transmitted to each male screw rod by low-speed forward rotation, and the rotation of the motor 9 is transmitted to each male screw rod by the second rotation transmission mechanism /. If it is transmitted to , it is high-speed reverse rotation.

A base /9 that is raised and lowered by each of the male screw rods 7 is installed inside the frame /. This base/9 is a quadrilateral frame-like frame consisting of four horizontally long tables 9 located between adjacent columns 3, 3, and the ends of the adjacent tables m are connected with a connecting member, 2/. The connecting member 21 is provided with a female thread (not shown) that is screwed into the male threaded rod 7, and is also provided with two wheels that slide on the surface of the support column 3. Therefore, when each male screw rod rotates forward at a low speed, the base 9 moves down at a low speed, and when each male screw rod 7 rotates at a high speed in a reverse direction, the base 9 moves up at a high speed.

A drive machine 23 consisting of a motor and a speed reducer is installed at one end of the table 20 of the base/9 described above, and the table 20
Rotation is transmitted between the drive shaft 23 extending in the length direction of the drive shaft 21 and supported by a bearing 21I, and when the drive machine n is driven, the drive shaft rotates. The driving shaft mystery is a shaft with a polygonal cross section, a shaft with a groove, a spline shaft, etc., and FIG. 6 shows the shaft with a groove.

A groove-shaped guide 2 is formed at the front end of each table 20 in parallel with the drive shaft 2S, and each drive shaft S is guided by the guide 2 and can move in the left-right direction along the length of the table. An actuation mechanism core is provided.

This operating mechanism 27 consists of two parallel first arms 2g, 2g.
and two second arms 29, 29 which are articulated to the first arm 2g, 2g.

Then, the key 1 of the sleeve 30 passed through the drive shaft 2S?
/ is placed in the groove of the drive shaft 2♂ to rotate the sleeve 30 together with the drive shaft 30 and support it so that it can move along the drive shaft 30, and the three first sprockets are fixed at the center of the sleeve 3θ. Install it in a shape.

Further, on the left and right sides of the sleeve 30, there are brackets l provided at one end of the first arm Jff via a bearing mechanism 33.
-31I is produced. Therefore, when the drive shaft rotates, the first three sprockets also rotate, but the first arm no.
does not rotate. Further, the sleeve 30 can move freely in the axial direction of the drive shaft 25, and the first arm M can rotate about the bracket 31I.

The tip of the 17th arm M, 2g described above and the base end of the second arm 29.29 described above are pivotally connected by the shaft 35, so the second arm 2q can rotate about the shaft 3j as a fulcrum. A second sprocket 36 and a third sprocket 3 integral with the second sprocket 36 are freely mounted on the shaft 3S,

A fourth sprocket llo and a pawl member lI/ are loosely mounted on a shaft 39 provided at the tip of the sprocket, and the second chain is connected to the third sprocket 37 and the fourth sprocket tog θ.

Therefore, when the first drive shaft 25 rotates, the first chain 3
g and the second chain rotation causes the claw member lIl to rotate.

101 The apparatus for removing excess portions of paperboard for packaging containers according to the present invention includes a plurality of the above-mentioned operating mechanisms 27 arranged in parallel on each table,
Each operating mechanism of each table J, 2? is inserted through one drive shaft 2S.

Surplus parts d on the four sides of the paperboard due to the above-mentioned removal device
In order to remove this, each male threaded lever is rotated in reverse at high speed by the drive mechanism g to position the base/9 above the frame/.
The left side of the running cart loaded with the paperboard laminate α is moved to the center inside the frame. Then, by the operation of the cylinder O, the press plate t' presses the paperboard stack α from above, and the drive mechanism rotates each male threaded rod 7 forward at low speed to gradually lower the base/9, and the base/9 is gradually lowered. When the claw member 9/ at the tip of the actuation mechanism 27 comes close to the top surface of the paperboard stack α, the drive mechanism g is stopped to stop the lowering of the base/9. Next is the individual operating mechanism, 2? Adjust the claw member to the most appropriate position. Actuation mechanism, 2? The adjustment operation is to tighten the tightening bolt lI? Loosen the , move the actuating mechanism core along the guide 2, and when the claw member f/ is at the most appropriate position on the paperboard, tighten the tightening pole +9. As a result, the position of the claw member lI/ in the left-right direction along the length direction of the table is set. Next, when the screw 3.2 and the first nut sy are loosened and the first male screw is rotated, the first receiving plate aS, which is screwed onto the first male screw qB, moves up and down, so that the first arm bar is driven. It rotates around axis J as a fulcrum, and the claw member D/ mainly moves up and down.

When the claw member lI/ is at the proper height position, the screw and the first nut 3g are tightened to fix the first arm 2g.

Next, when the second male screw (N) AI is loosened and the second male screw S7 is rotated, since the second male screw N is screwed into the second receiving plate, it moves in the axial direction, and the second arm 29 is rotated. It rotates about the shaft 35 as a fulcrum, and the claw member moves mainly in the front-back direction. When the claw member D/ is in the proper front and back position, the second nut 6/ is tightened to press the second collar 10 onto the second receiving plate and fix the second arm 29.

Each adjustment operation of the operating mechanism described above is performed depending on the state of the surplus portion d of the paperboard. That is, the inside of the paperboard from the cutting line G becomes a part of the container, and therefore cannot be brought into contact with the claw member IIl. Also, if the claw member / is brought into contact at the position closest to the cutting line C of the surplus portion d, the surplus portion d
can be scraped off most effectively from cutting line C. Therefore, in the area where the surplus portion d is wide, the first angle adjustment mechanism and the second angle adjustment mechanism 33 are operated so that the claw member lI/ is located forward, and the first arm and second arm 29 are adjusted as shown in FIG. It is extended as shown by the solid line, and the lower surface of the claw member 4// is brought into contact with the lower surface of the surplus portion d. Also, if the cutting line C approaches the edge of the paperboard and the surplus portion d is narrow, the first
Using the angle adjustment mechanism and the second angle adjustment mechanism, the first arm 2g and the second arm 9 are folded into a dogleg shape as shown by the chain line in FIG. 4, and the claw member lll is positioned at the rear near the table. Further, the vertical position of the claw member 1I/ is set so that the lower side surface of the claw member 11/ is in contact with the edge of the paperboard.

In this way, each actuating mechanism core is adjusted individually, and when each claw member d/ is in the most appropriate position, the driving mechanism 3 of each table 9 is driven to rotate the driving shaft, and at the same time, the driving mechanism g , each male threaded rod 7 is rotated forward at low speed to lower the base/9 at low speed. As a result, the claw member 4 (/
rotates at a high speed to scrape off the excess portion d of the paperboard from the cutting line C and sweep it out to the outside of the frame 9, and the lower portion of the paperboard is sequentially removed by lowering the base 9 at a low speed.

When the base/9 has been lowered to its lowest point, all the excess paperboard on the cart j has been removed, so the drive mechanism 3 of each table 20 is stopped, and the drive mechanism g is used to rotate each male screw rod 7 at high speed in reverse. When the base 19 is raised to the highest level, the drive mechanism is stopped and the trolley 3 is pulled out from the frame 1.

The operation of the removal device described above is just one example, and various operations can be automated as appropriate.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and may be modified as appropriate without changing the gist.

(Effects of the Invention) In summary, according to the present invention, as long as the dimensions of the paperboard are not changed to a large width, the excess portions on the four sides of the paperboard of any size can be removed extremely quickly and reliably. can do. In addition, no matter what shape the surplus part outside the cutting line of the paperboard has, it can be reliably removed by adjusting the position of the claw member, so it can be used regardless of the shape of the container, and is of high practical value. becomes.
