Description

  The present invention relates to a method for removing paper dust, thread-like waste, paper pieces, and the like, which are generated when punched shapes and holes of various shapes are punched and formed on corrugated cardboard, paperboard, and the like, and an apparatus for removing the same.

An assembly box made of corrugated cardboard or paperboard is formed by punching out a developed shape of a product from rectangular corrugated cardboard or paperboard.
The punching is performed by a flat punching die in which a punching blade (straight blade, wave blade) is implanted in a base plate, or a cylindrical punching die in which a punching blade (straight blade, wave blade) is implanted in a semi-cylindrical plywood. However, if the same operation is repeated, the cutting edge of the punching blade implanted and fixed in the punching die is worn and becomes a flat surface. When punching with the worn punching blade, the product is punched by surface cutting, and paper dust and paper thread scraps are generated on the cut surface. Then, paper dust and paper thread scraps adhere to the outer peripheral edge of the product to be punched out (outside edge, hole edge, groove edge, etc. of the product) due to static electricity. In addition, even if the paper dust and paper thread-like waste are separated into the product and surrounding waste by a stripping device (dropping waste dropping) in the next step of the punching process, it remains attached to the outer peripheral edge of the product sheet. Become.

  By the way, paper dust and paper thread scraps adhering to the outer peripheral edge of the punched product significantly reduce the product value, and when the punched product is put on an automatic box making machine, paper dust and paper thread scraps are driven. There is a problem that a trouble occurs due to entering a department or the like. In particular, recently, mixing of paper dust, filamentous waste, paper pieces, and the like in cardboard cases has become a problem.

  Therefore, in the past, product sheets to be carried out after stripping (for example, 1 batch: 25 sheets or 50 sheets laminated) are manually sandwiched between product sheets while being manually pulled apart one by one. Paper dust, thread waste, and paper pieces are dropped and stacked on a pallet, and the outer periphery of the stacked product is rubbed with a brush or mop to adhere to the outer periphery of the product sheet, paper thread Debris is removed.

However, only the outer peripheral edge of the stacked product sheets can be rubbed by the above-mentioned brush or manual work with a mop, and it adheres to the hole formed inside the product sheet or the groove extending from the outer peripheral edge to the inside. Paper dust and paper thread debris cannot be removed even by pulling and tapping in the previous stage. In addition to the manual work described above, there is a means for removing paper dust and thread waste by a brush between two roll brushes that are mechanically driven. Paper dust and filamentous waste adhering to the surface cannot be removed.
In addition, the existence of the technical literature related to the above-described prior art is unknown.

  The present invention has been made in view of the problems of the above-described conventional technology, and the object of the present invention is paper dust, thread-like waste adhering to a product sheet batch-delivered from a punching machine or stripping machine, It is an object of the present invention to provide a method and a removing apparatus that can remove a piece of paper reliably and efficiently.

  In order to achieve the above-mentioned object, the paper dust / paper piece removing method taken by the present invention is to put a horizontally stacked paper punched product sheet, which is carried out in a batch, into a standing state before transporting it in a standing state. By brushing the lower peripheral surface (front end surface along the conveyance direction) and then changing the posture to the upright state, the sheet is released one by one by releasing the close contact lamination state. Paper dust removal means consisting of a brush that performs linear motion and rotational motion, and air spraying is used to remove paper dust, thread-like debris, or paper pieces intervening between product sheets by pulling them apart and blowing air. Paper dust and thread-like debris adhering to the three outer peripheral surfaces (upper end surface and left and right end surfaces) excluding the lower side of the product sheet are removed, and the posture is changed from the standing state to the horizontal state and then carried out. The outer peripheral surface of the product sheet It was to be over.

In particular,

And the process is performed continuously (Claim 1).
By the above method, not only paper dust and thread-like waste adhering to the outer peripheral surface of the batch-delivered product sheets, but also paper dust, thread-like waste, paper pieces and the like sandwiched between the product sheets stacked and stacked, It can be reliably removed while continuously conveying in batch form.

  In the spraying of air in the above method, -air may be mixed and sprayed. -When air containing ions is blown onto the product sheet, static electricity can be removed, and paper dust that is removed by brushing and suspended in the air can be prevented from reattaching to the product sheet. Further, it is possible to prevent dust and dust from adhering.

  In addition, the outer peripheral edge paper dust removing step is configured by arranging unit bodies that protrude and retract independently so that the contact pressure of the brush rubbing the end face of the product sheet does not change depending on the location. The juxtaposed brush unit (paper dust removing unit) moves in and out in accordance with the outer shape of the product sheet. And the unit body which comprises the brush is comprised with two types of brushes from which a motion differs, and the effect of paper dust removal is heightened (Claim 2).

An apparatus for carrying out the above method is:
(A) a front end paper dust removing means for aligning the front end face of a batch-form punched product sheet carried in a horizontally stacked state and brushing to remove paper dust;
(B) Standing conveyance means for converting the punched product sheet in the form of a batch that has completed the removal of the paper dust on the front end surface into a standing state for each batch and conveying the batch,

(F) The batch-unit product sheet from which the paper dust has been removed is again converted into a horizontally laminated state and carried out. During the carrying out process, the left and right side surfaces of the product sheet are fixed brushes, and the front and rear end surfaces are moved with a movable brush. A final makeup means to remove,
And from the horizontal carry-in of the product sheet to the horizontal carry-out after the paper dust is removed (Claim 3).

  Standing transport means that transports product sheets that are carried in a horizontally stacked state (batch form) with the posture changed to a standing state, and accommodates a batch of side U-shaped batches on the outer peripheral surface of a plurality of endless belts that endlessly rotate in parallel. The frame is configured to stand up and fix at equal intervals in the circumferential direction of the endless band with the open side facing outward (Claim 4). With this configuration, punched product sheets conveyed by the carry-in conveyor are pushed into and accommodated in each batch storage frame at the transfer section from the carry-in conveyor arranged on the upstream side. Be done

The separating means separates the product sheets in close contact, which are accommodated and supported in the batch accommodating frame of the upright conveying means, one by one, and adhering to the paper dust and thread waste adhering to the front and back surfaces of the sheets, and between the sheets This is performed to remove a piece of paper sandwiched between the two.
This separation means mechanically moves up and down the product sheet stored in the batch storage frame of the upright conveying means with the lower end surface flush with the endless belt. An endless belt comprising: a driving and rotating conveyor belt arranged in a predetermined length along the belt conveyance direction; and an eccentric cam that moves the conveyance surface at the center of the conveyance belt in the length direction upward and downward from the bottom surface of the batch. The punched product sheets that are conveyed in batch by the rotation of the punched product are moved up and down in the batch receiving frame, and the punched product sheets that are in close contact with each other are separated and separated one by one (claim 5). The separation means is not limited to the vertical vibration method using the eccentric cam, and other methods may be used.

  Further, the paper dust removing means comprises a side surface removing means arranged opposite to a position sandwiching the conveying path of the standing conveying means, and an upper surface removing means arranged above the conveying path, and each removing means is a product sheet. A large number of paper dust removal units (brush units) that are configured by sequentially arranging guide plates, linear reciprocating brushes, and rotating brushes from the front side along the conveyance direction are arranged in parallel with the product sheet conveyance direction. Further, each paper dust removing unit is configured so that the linear reciprocating brush and the rotating brush can move in and out to a position where they slide on the end surface of the product when the moving product sheet comes into contact with the guide plate.

The paper dust removing unit that constitutes the paper dust removing means attaches a linear reciprocating brush and a rotating brush to the mounting board to which the guide plate is attached, and the linear reciprocating brush converts the rotation of the rotating brush into a linear motion via linkage. The mounting board supports the fixing member so as to be elastically slidable, and the rotating brush fixes the pinion gear to the shaft of the brush, and the pinion gear is slidable with respect to the fixing member. It is set as the structure meshed with the attached rack (Claim 7).
The rotation range (rotation angle) of the rotary brush is determined by the rotation angle of the pinion gear that is rotated by sliding the rack, and the moving distance of the linear reciprocating brush that is linearly reciprocated by the rotation angle is also determined.

  Moreover, although the above-mentioned paper dust removal apparatus may be used independently, it can also be used by docking with another apparatus. For example, on the downstream side of the transfer means in the paper dust removing device, the stationary waste / paper dust removing device that punches out the waste remaining in the product sheet by the upper and lower molds and removes the paper dust at the time of punching with a blower From the loading of the punched product sheet into the upright conveying means to the unloading from the stationary debris / paper dust removing device may be performed automatically and continuously. In this case, the quality of the product can be improved efficiently.

The method for removing paper dust / paper pieces from a paper punched product according to the present invention is stacked according to the structure of claim 1 as well as paper dust and filamentous waste adhering to the outer peripheral surface of a product sheet that has been batched. Paper dust, filamentous waste, paper pieces, etc. that are sandwiched and adhered between product sheets can be reliably removed while being continuously conveyed in batch form.
And when it is set as the structure of Claim 2, even if the shape of an outer periphery has an unevenness | corrugation, a brush can be made to contact uniformly according to the uneven | corrugated shape, and also the brush which rubs the end surface of a sheet | seat also differs in a motion. Since it rubs with two types of brushes, it is possible to reliably remove paper dust and thread waste.

  Furthermore, the paper dust / paper piece removing device is configured as claimed in claim 3 to ensure that the paper dust and thread scraps adhering to the outer periphery of the product sheet and the paper dust and paper pieces sandwiched between the sheets are continuously conveyed. Can be removed.

Further, according to the configuration of the fourth aspect, a batch-type product sheet carried in a horizontally stacked state can be automatically converted into a standing state optimal for paper dust removal and conveyed.
Furthermore, the structure according to claim 5 can reliably separate the product sheets conveyed in a close-stacked state one by one, and thus effectively eliminates paper dust, thread waste and paper pieces sandwiched between the product sheets. Can be removed.

Further, according to the configuration of the sixth aspect, it is possible to surely remove the paper dust and the thread-like waste adhering to the left and right end surfaces and the upper end surface of the product sheet.
When the paper dust removing unit is configured as described in claim 7, the linear reciprocating brush and the rotating brush for effectively removing the paper dust and the filamentous waste can be driven by a single driving source, and it is inexpensive. Can be configured.

Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
An assembly box such as a cardboard case is formed by punching a developed shape of a target assembly box from a material such as cardboard or cardboard, and assembling the punched product sheet. The punching of the product sheet is performed by punching the paperboard of the material with a flat plate punching machine or a rotary die cutter, and after the punching, the scraps on the outside of the product part and various shapes of holes and grooves processed inside the product are removed. To be completed.
By the way, paper dust and thread-like waste are generated in the outer peripheral edge of the product sheet and various shapes of holes and grooves formed in the product by the punching. We propose a method for automatically and efficiently removing paper dust and filamentous waste by mechanical force.

  In that method, a predetermined number of sheets (generally 25 sheets or 50 sheets) are stacked (horizontally stacked) and transferred into a batch after the punching is completed and the waste on the outer periphery and the waste inside the product are dropped. However, while conveying the punched product sheet that is batch-loaded in the horizontal state, the paper sheet and thread scraps adhered to the front and back surfaces of the product sheet, the outer peripheral edge, the hole or groove inside the product, and the product Removes paper dust, filamentous waste, paper pieces, etc. sandwiched between sheets.

Specifically, the punched product sheets carried in batch are processed by passing the following steps continuously.
(A) a front end paper dust removing step of brushing the front end face of a punched product sheet carried in a batch form in a horizontally laminated state to remove paper dust;
(B) an upright conveying step of converting the punched product sheet in a batch form that has completed the removal of the paper dust on the front end surface into an upright state and conveying it;
(C) a separation step of separating the punched product sheets that are in close contact in batch units one by one during the standing conveyance step;
(D) A sheet front / back surface paper dust removing step for removing paper dust / paper pieces adhering to the front / back surface of the product sheet by blowing air to the separated punched product sheet;
(E) The separated punched product sheets are arranged in batch units, and in that state, the paper dust adhering to the left and right end surfaces and the upper end surface of the product sheet is removed by brush and / or air blowing;
(F) The final makeup process in which the batch unit product sheet from which the paper dust has been removed is again converted into a horizontally laminated state and carried out, and the outer peripheral surface of the batch unit product sheet is brushed during the carrying out process;
It consists of

  Then, the product sheet that is carried out after the removal of paper dust, paper pieces, etc. is carried out so that the printing surface applied to the product sheet is directed upward in relation to the processing in the next step. Therefore, when the delivery form of the product sheet carried into the standing conveyance process is different from the normal form (printing surface is downward: bottom printing), it is necessary to reverse the product sheet during the transition to the standing conveyance process. That is, when the product sheet is carried in (top printing) with the printing surface facing upward, it is reversed before moving to the standing conveyance process.

The air that is erected in the upright conveying process and separated and separated in the separation process and sprayed onto the product sheet may be air alone, but the air may be sprayed with ions contained therein to take antistatic measures. The air blowing may be performed not only from the upper direction but also from the left and right directions on the product sheet that is erected and conveyed.
Further, after the separated and separated product sheets are aligned, paper dust is removed (brush rubbing and air blowing) on the left and right side end surfaces and the upper end surface of the product sheet, but the order is not limited. For example, the processing is performed in the order of paper dust removal on the left and right end faces → paper dust removal on the upper end face.

In (a), the sheet moves up and down by the rotation of the belt while swinging up and down, and the sheets are separated one by one.

  Further, on the downstream side of the separating means A3 between the chains 16 and 16 'of the upright conveying means A2, a conveying conveyor 55 comprising a plurality of belt conveyors has its conveying surface slightly above the bottom surface of the batch receiving frames 17 and 17'. And the rotation speed of the conveyor 55 is controlled to rotate at the same speed as the rotation speed of the upright conveying means A2. The drive rotation of the conveyor 55 is not limited to the method of rotating using the rotational force of the separating means A3, and other methods may be used.

Above the separating means A3, air blowing means A4 is disposed for blowing air to the separated punched product sheet to remove paper dust, paper pieces and the like adhering to the front and back surfaces of the product sheet.
This air blowing means A4 is a moving means such as a ball screw mechanism (illustrated) so that air can be blown from an optimum position according to the size of the product sheet a to which the nozzle 21 for blowing air is supplied. Omitted) is supported so that it can be adjusted up and down, and negative ions are included in the air to be blown, so that an effect of removing static electricity is imparted and dust and the like are prevented from adhering to the static electricity.

  Therefore, the paper dust adhered to the front and back surfaces of the product sheet a and the paper pieces sandwiched between the product sheets a by the action of the air blowing means A4 and the separating means A3 are located below the upright conveying means A2. It is dropped and removed.

On the downstream side of the separating means A3, on the side of the upright conveying means A2, paper for removing paper dust adhering to the left and right end faces and the upper end face of the product sheet a accommodated and conveyed in the batch accommodating frames 17 and 17 ′. Powder removing means A5 is arranged.
The paper dust removing means A5 is disposed opposite to a position sandwiching the conveying path of the upright conveying means A2, and the side surface removing means A5-1 for removing the paper dust adhering to the left and right end surfaces of the product sheet, and the conveying of the standing conveying means A2. The upper surface portion removing means A5-2 is disposed above the path and removes paper dust adhering to the upper end surface of the product sheet a. They are arranged in the order of the side surface removing means A5-1 and the top surface removing means A5-2 in the transport direction.

  The side surface removing means A5-1 and the upper surface removing means A5-2 are arranged in the order of the guide plate 23, the linear reciprocating brush 24, and the rotating brush 25 from the near side toward the conveying direction of the standing conveying means A2. A large number of paper dust removing units 22 configured as described above are arranged in a horizontal row so as to be orthogonal to the conveying direction of the product sheet. That is, in the case of the side surface removing means A5-1, the paper dust removing unit 22 is arranged in a multi-stage straight line from the position where the bottom surface portions of the batch receiving frames 17, 17 'of the upright conveying means A2 are positioned in the vertical direction. In the case of the removing means A5-2, the paper dust removing units 22 are arranged in parallel in a horizontal horizontal line above the batch receiving frames 17 and 17 'on the forward path side of the standing conveying means A2. Then, the side surface removing means A5-1 opens and closes in the width direction according to the size (horizontal width) of the product sheet a (see FIG. 7), and the top surface removing means A5-2 is the size of the product sheet a (in the conveying direction). It is configured to move up and down in accordance with (length) (see FIG. 8) and to move and adjust to the optimum position.

The paper dust removing unit 22 attaches a guide plate 23 to one side in the longitudinal direction of a rectangular mounting board 26, and linearly reciprocates the linear reciprocating brush 24 at a position forward of the guide plate 23 (moving direction of the product sheet). The rotary brush 25 is rotatably attached to a position forward of the linear reciprocating brush so that the linear reciprocating brush 24 is driven by converting the rotary motion of the rotary brush 25 into a linear motion by a linkage 27. Yes.
The mounting substrate 26 is supported so as to be elastically slidable with respect to a fixing member 28 that can be adjusted in the width direction or the vertical direction, and the left and right end surfaces and the upper end surface of the product sheet a conveyed thereby are mounted. The mounting substrate 26 that supports the linear reciprocating brush 24 and the rotating brush 25 by moving while abutting on the guide plate 23 fixed to the substrate 26 moves in and out with respect to the fixing member 28, and the end surface of the product sheet a and the brush Ensure optimal contact relationship. Each unit of the paper dust removing unit 22 appears and disappears corresponding to the outer shape (uneven shape) of the product sheet a, and the outer peripheral end surface of the product sheet a can be reliably rubbed with a brush.

The rotational force of the rotary brush 25 serving as a drive source for the linear reciprocating brush 24 is such that the pinion gear 29 is fixed to the shaft 25a of the rotary brush 25 rotatably supported on the mounting substrate 26, and the rack 30 meshes with the pinion gear. Is slidably attached to the fixing member 28, and the pinion gear 29 is rotated by sliding the rack 30, and the brush fixed to the opposite side of the shaft 25a is rotated. The driving force for sliding the rack 30 attaches the rotating plate 32 to the output shaft of the motor 31, attaches one end of the linkage 33 to the rotating plate 32, and fixes the rack 30 to the other end of the linkage 33. The rack 30 is connected to the base plate 30 ′ so that the rack 30 is reciprocated by a predetermined distance by the rotation of the motor 31. (See Figs. 7 and 8)
As an example of driving, when the rack 30 reciprocates 53 mm by the rotation of the motor 31, the rotating brush 29 reciprocates in an angle range of 135 ° via the pinion gear 29 meshing with the rack 30 to linearly reciprocate. The brush 24 slides back and forth 29 mm.
The rack 30 is configured so that the engagement between the pinion gear 29 and the rack 30 is maintained within the range in which the mounting substrate 26 supporting the rotating brush 25 moves in parallel with respect to the fixed member 28. Therefore, it has a predetermined width.

The rotating brush 25 may be attached with the center (O) of the base plate on which the brush is planted being aligned with the center (O ') of the shaft 25a, but the center of the base plate is the center of the shaft 25a as shown in the figure. May be attached eccentrically (L). In this case, since the rubbing range by the brush moves in the radial direction due to the eccentric mounting of the brush base plate, the gap between the rotating brushes generated when the paper dust removing units 22 are arranged side by side can be covered by the eccentric rotation.
