For example, in the blank sheet take-out device disclosed in Patent Document 1, the lower end side of the leading blank sheet accumulated in the magazine is adsorbed by the sub-adsorption mechanism and separated from the subsequent blank sheet, and then the main adsorption The mechanism is configured to adsorb a portion near the lower end of the leading blank sheet and take it out of the magazine.
No. 7-445

  However, in the conventional apparatus, since both suction mechanisms suck the same end side (lower end side) of the blank sheet, if the separation distance of the sheet separation by the secondary suction mechanism is increased, the main suction mechanism is attached to the leading blank sheet. When the sheet comes into contact, the amount of the sheet that escapes to the magazine increases, so the sheet suction by the main suction mechanism becomes unstable, the separation amount cannot be increased so much, and the reliable sheet separation by the sub suction mechanism is not performed. There is a fear.

  That is, the present invention has been proposed in order to solve the above-mentioned problems inherent in the above-described conventional technology, and is a blank sheet auxiliary separation device that can satisfactorily separate a blank sheet. The purpose is to provide.

In order to overcome the above-mentioned problems and achieve the intended purpose suitably, the auxiliary separation device for blank sheets according to the present invention comprises:
A sheet assist that pre-separates the blank sheet from the subsequent blank sheet before the first blank sheet is picked up and taken out by the suction part of the sheet transfer means from the take-out port of the sheet magazine in which the blank sheets are stacked in an upright position. A separation device,
The take-out port is provided with a lower end supporting member that supports the lower end of the leading blank sheet and an upper end supporting member that supports the upper end,
The upper and lower ends are supported by the both support members, and auxiliary suction means including an adsorption member that adsorbs the lower side than the support position by the upper end support member on the upper end side of the leading blank sheet facing the take-out port,
The adsorption member of the auxiliary suction means, is separated while supporting the upper and lower end portions by adsorbing the upper end portion of the blank sheet by the both supporting members from the rear connection of the blank sheet the head of the blank sheet of the beginning, the The lower end portion of the blank sheet that is on the different upper and lower end sides with respect to the adsorption position of the adsorption member is adsorbed by the adsorption portion of the sheet transfer means, and the upper end portion of the blank sheet is pulled downward from the upper end support member. It is characterized in that the blank sheet is taken out by the sheet transfer means so as to be pulled out .

  According to the blank sheet auxiliary separating apparatus of the first aspect of the present invention, the upper end side of the blank sheet to which the lower end side is adsorbed by the sheet transfer means when being taken out from the sheet magazine is adsorbed in advance by the auxiliary adsorbing means. Since it is configured to separate from the subsequent blank sheet, the separation amount of the sheet separation by the auxiliary suction means can be increased, air can easily enter the gap formed between the sheets, and the leading blank sheet can be favorably separated. . In addition, since the upper end side of the blank sheets stacked in a standing posture is a free end, the upper end side of the attracted leading blank sheet is easy to move, and a good gap is formed between subsequent blank sheets. The separation operation is good. Furthermore, since the lower end portion of the leading blank sheet is not separated from the succeeding blank sheet, the separation interval of the leading blank sheet with respect to the succeeding blank sheet at the suction position for the blank sheet of the sheet transfer means is small, Even when the blank sheet is taken out at a high speed, it is possible to satisfactorily hold and hold the blank sheet by the sheet transfer means, and the sheet is not broken even when the sheet transfer means hits the blank sheet.

  According to the blank sheet auxiliary separating apparatus of the second aspect, since the auxiliary suction means is disposed at a position where it does not come into contact with the blank sheet to be taken out, the auxiliary suction means is placed before the blank sheet is taken out by the sheet transfer means. It is only necessary to perform the pre-separation operation performed in (1), the apparatus configuration is simplified, and high-speed operation is possible.

  According to the blank sheet auxiliary separating apparatus according to claim 3, since the adsorption member is brought into contact with and separated from the blank sheet by the motor, the synchronization operation with the sheet conveying means is easy, and the blank by the sheet conveying means is provided. Correspondence between taking out of the sheet and preliminary separation by the auxiliary suction means is improved.

  According to the blank sheet auxiliary separating apparatus according to claim 4, by rotating the motor at a non-uniform speed, the operation when the adsorption member adsorbs the leading blank sheet is slowed to improve the adsorption. Can do. Further, the operation of the suction member when the sheet transfer means sucks the leading blank sheet can be delayed, and the leading blank sheet can be favorably attracted by the suction portion of the sheet transporting means.

  According to the blank sheet auxiliary separating apparatus of the fifth aspect, it is possible to cope with the size change of the blank sheet.

  Next, a preferred embodiment of the blank sheet auxiliary separating apparatus according to the present invention will be described below with reference to the accompanying drawings. For convenience of explanation, “left and right” refers to a direction that intersects the conveyance direction of the blank sheet in the sheet magazine.

  As shown in FIG. 1, a wraparound type caser 10 (hereinafter referred to as a caser) employing a blank sheet auxiliary separating apparatus according to an embodiment includes a sheet magazine 12 that stacks a plurality of blank sheets 11 in an upright posture. Prepare. The sheet magazine 12 is provided with a sheet feeding means 14 provided with two conveying shafts 13 and 13 (only one of which is shown) on which the blank sheet 11 is placed, spaced in parallel in the left-right direction. The shafts 13 and 13 are continuously rotated in one direction by corresponding drive motors 15 and 15 (only one is shown). Each transport shaft 13 is disposed so as to be inclined downward toward the take-out port 12a of the sheet magazine 12 with respect to the horizontal plane, and the transport shaft 13 is provided with a take-out port for the blank sheet 11 placed by the rotation thereof. A spiral groove is formed in a direction to be propelled toward 12a, and the blank sheet group is conveyed by rotation of both conveying shafts 13 and 13, and the leading blank sheet 11 is taken out to the take-out port 12a. The blank sheet 11 is accumulated in the sheet magazine 12 in such a posture that the inner surface when the box is made (hereinafter referred to as the inner side during box making) faces the downstream side (the extraction port 12a) in the sheet conveying direction. The inner side surface during the box making is sucked and held by a sheet transfer means 33 described later and is taken out from the take-out port 12a.

  A shutter 16 as a lower end support member for separating the leading blank sheet 11 taken out from the take-out port 12a and the subsequent blank sheet 11 at the front end facing the take-out port 12a in each of the transport shafts 13, Each of them is arranged to rotate integrally. Each shutter 16 is formed in a disk shape having a diameter larger than that of the conveying shaft 13, and left and right corners (lower ends) of the lower end side of the leading blank sheet 11 facing the takeout port 12 a at a portion protruding in the radial direction from the shaft 13. Part) are configured to support each. Each shutter 16 has a notch (not shown). When the notch arrives at a separation position corresponding to the lower edge of the blank sheet 11, the sheet 11 is allowed to pass (take out). Configured to allow. Both the shutters 16 and 16 are set to rotate once corresponding to the operation of taking out one blank sheet 11 by the sheet transfer means 33.

  Auxiliary suction means 17 for separating the upper end side of the leading blank sheet 11 from the succeeding blank sheet 11 is disposed on the outer upper side of the take-out opening 12 a in the sheet magazine 12. As shown in FIG. 2, the auxiliary suction means 17 includes first suction cups 18 and 18 as suction members for sucking the upper end of the inner side of the blank sheet 11 at the time of boxing, and the suction cup 18. , 18 is basically composed of a rotating crank mechanism 19 as a moving mechanism for moving the crank mechanism 19 toward and away from the blank sheet 11 and a variable speed motor (motor) 20 such as a servo motor for operating the crank mechanism 19. That is, the auxiliary suction means 17 is pivotally supported by a base 22 disposed on the machine casing 21 of the caser 10 so that a pivot 23 extending in the left-right direction is rotatably supported as shown in FIG. A pair of actuating members 24 and 24 (only one is shown) are fixed apart from each other in the left-right direction, and the actuating members 24 and 24 are configured to be swingable about the pivot 23. A first suction cup 18 is provided at the lower end of each actuating member 24 and faces the inner side of the leading blank sheet 11 facing the take-out port 12a. Not connected to the suction means.

The base 22 is provided with the variable speed motor 20 and the rotating crank mechanism 19 that is operated by the motor 20 and is connected to one operating member 24. 2 and 3, the rotary crank mechanism 19 is connected to the variable speed motor 20 via a transmission means 25 such as a pulley or a belt and rotated in a predetermined direction, and the eccentricity of the disk 26. One end is connected to the position and the other end is connected to the vicinity of the lower end of the actuating member 24. Then, by rotating the crank disk 26 in a predetermined direction by the variable speed motor 20, the pair of operating members 24, 24 swing around the pivot 23 via the linkage 27, and thereby the pair of first suctions. The cups 18 and 18 are configured to move between a forward position where the cups 18 and 18 are in contact with the upper end side of the leading blank sheet 11 and a backward position where the cups 18 and 18 are separated outward. Incidentally, based on the timing signal from the Timing in g setting means not shown, suction means connected to the first suction cups 18 and 18, ON while the adsorption cup 18 is moved to the advanced position from the retracted position It is actuated to allow the blanking sheet 11 to be sucked by the suction cups 18 and 18 at the forward position, and is turned OFF while moving from the forward position to the vicinity of the reverse position, and the first suction cup 18 near the reverse position. , 18 is set to cancel the suction of the blank sheet 11.

  The auxiliary suction means 17 is provided with a synchronization means 28 for synchronizing the operation of the first suction cups 18, 18 and the operation of the sheet transfer means 33. As a result, the variable speed motor 20 is rotated at a constant speed in synchronism with the removal of one blank sheet 11 by the sheet transfer means 33 in the embodiment. During this time, the first suction cups 18 and 18 reciprocate once, and the suction cups 18 and 18 are in the vicinity of the retreat position where the suction cups 18 and 18 are most retracted from the outlet 12a (the crank disk 26 is rotating but the first suction cups are rotating). The sheet transfer means 33 is set so as to adsorb the leading blank sheet 11 when the movement of 18 is in a small movement range.

  A bracket 29 extending toward the take-out port 12 a is disposed on the base 22, and a support bar 30 extending in the left-right direction is disposed at the extending end of the bracket 29. At the left and right ends of the support bar 30, rollers 31 (only one is shown) as upper end support members are rotatably disposed, and the rollers 31 in the leading blank sheet 11 facing the take-out port 12a. The auxiliary suction means 17 is configured to support the upper end portion above the suction position by the first suction cups 18, 18. The leading blank sheet 11 facing the take-out port 12 a is supported at the lower end by the shutters 16 and 16 and supported by the rollers 31 and 31 at the upper end. The rollers 31, 31 are arranged in such a position that the leading blank sheet 11 is placed in a posture substantially orthogonal to the transport shafts 13, 13. Therefore, the direction in which the blank sheets 11 stacked in the sheet magazine 12 are arranged (the sheet conveyance direction of the conveyance shaft 13) is inclined with respect to the horizontal plane, and the upper end portion of the blank sheet 11 in the sheet magazine 12 is inclined forward. (See Figure 1).

  A guide 32 extending toward the take-out port 12a is provided in the support rod 30 in the vicinity of the position where each roller 31 is provided, and the guide 32 guides the upper end of the blank sheet 11. Configured (see FIG. 2). The base 22 is disposed so as to be movable in the vertical direction with respect to the machine casing 21. The first base 22 is operated manually or by a driving means such as a motor by operating an adjusting mechanism such as a screw shaft (not shown). The suction position of the blank sheet 11 by the suction cups 18, 18 can be adjusted.

  Outside the take-out port 12a in the sheet magazine 12, below the auxiliary suction means 17, there is a sheet transfer means 33 for taking out the blank sheets 11 one by one from the sheet magazine 12 and delivering them to the case conveying conveyor 36 described later. It is arranged. As shown in FIG. 1, the sheet transfer means 33 includes a plurality of second suction cups (suction portions) 34, and a plurality of sets of take-out portions 35 to which a required operation is given by a rotation mechanism (not shown). In the example, there are two sets, but there may be three or more sets), and each takeout unit 35 is configured to take out the blank sheets 11 from the sheet magazine 12 one by one. Each second suction cup 34 is connected to a suction means (not shown), and the suction means is ON / OFF controlled at an appropriate timing, so that the suction holding and blanking of the blank sheet 11 by each second suction cup 34 are performed. Is set to do. Each take-out portion 35 is close to the lower end side of the inner side surface during the box making of the leading blank sheet 11 facing the take-out opening 12a of the sheet magazine 12 and then is slightly separated from the take-out opening 12a when the sheet is taken out. It is configured to move upward and follow a trajectory that moves downward thereafter. As a result, the blank sheet 11 that is sucked and held by the take-out portion 35 and taken out from the sheet magazine 12 is taken away from the lower end portion of the subsequent blank sheet 11 so that the lower end side is lifted upward. After being taken out from the mouth 12a, the posture is changed so that the inner side (the suction surface by the second suction cup 34) at the time of box making faces upward and is moved downward. When the lower end portion of the leading blank sheet 11 is taken out from the take-out opening 12a, the notches of the left and right shutters 16 arrive at separation positions corresponding to the left and right corner portions of the lower end side, respectively. The sheet is set to be allowed to be taken out.

  The movement trajectory of the blank sheet 11 with the lower end side adsorbed by the sheet transfer means 33 and taken out downward is set so as not to interfere with the auxiliary adsorbing means 17 as shown in FIG. That is, the auxiliary suction means 17 is arranged outside the movement trajectory of the blank sheet 11 taken out from the sheet magazine 12 so that it does not have to be moved to a position where it does not interfere with the blank sheet 11 taken out by the sheet transfer means 33. It is.

  Below the sheet transfer means 33, a case transporting conveyor 36 having a transport direction opposite to the sheet transport direction in the sheet magazine 12 is disposed, and between the conveyor 36 and the sheet magazine 12 is disposed. A bending guide 37 is provided. The blank sheet 11 taken out from the sheet magazine 12 by the sheet transfer means 33 is folded in two by a bending guide 37 when delivered to the case transport conveyor 36. Further, the blank sheet 11 delivered to the case transporting conveyor 36 is provided on the conveyor 36 and is separated from the front and rear in the transporting direction in a state where the blank sheet 11 is folded so that the front side in the transporting direction stands upright. It is sandwiched by 36a, bent into a U-shape that opens upward, and is conveyed downstream in that state.

(Effects of Example)
Next, operation of the blank sheet auxiliary separating apparatus according to the above-described embodiment will be described.

  A plurality of blank sheets 11 are stacked on the sheet magazine 12 in such a manner that the lower ends are placed on the conveying shafts 13 and 13, and the upper end portion of the leading blank sheet 11 facing the take-out port 12a is placed on the roller. The blank sheet group is in a state where the upper end portion thereof is tilted forward by supporting the lower end portion with the shutters 16 and 16 while supporting the lower end portion with the shutters 16 and 31.

  When the take-out of the sheet by the sheet transfer means 33 is started, the auxiliary suction means 17 is moved before the take-out portion (second suction cup 34) 35 of the transfer means 33 sucks and holds the lower end side of the leading blank sheet 11. Operate. In other words, the rotary crank mechanism 19 is operated by the variable speed motor 20, and the first suction cups 18 and 18 facing the retreat position are advanced to the advance position, and are supported by the rollers 31 and 31 in the leading blank sheet 11. The first suction cups 18 and 18 come into contact with the upper end side below the position where the first suction cups 18 and 18 are held, and hold them by suction. Subsequently, the first suction cups 18, 18 are retracted from the advance position to the retreat position (away from the take-out port 12 a), whereby the blank sheet 11 sucked and held by the first suction cups 18, 18. Is separated from the upper end of the subsequent blank sheet 11 (the state of the two-dot chain line in FIG. 2). At this time, since the lower end portion of the leading blank sheet 11 is supported by the shutters 16 and 16, the lower portion (lower end side) of the blank sheet 11 is the lower portion (lower end side) of the subsequent blank sheet 11. Not far away from. Since the blank sheets 11 are stacked in a standing posture, the upper end side sucked by the first suction cup 18 is a free end that is easy to move, and the leading blank sheet is moved backward by the suction cup 18. A good gap is formed between 11 and the subsequent blank sheet 11. Further, since the roller 31 is employed as the upper end support member that supports the upper end of the leading blank sheet 11, the upper end of the sheet 11 is pulled out between the roller 31 and the subsequent blank sheet 11. There is little resistance, and it is well separated.

  When the first suction cups 18, 18 of the auxiliary suction means 17 approach the retracted position, the take-out portion 35 of the sheet transfer means 33 is close to the lower end side of the leading blank sheet 11 in the sheet magazine 12, The second suction cup 34 abuts against and holds the blank sheet 11 and the suction by the first suction cups 18 and 18 is released. At this time, the suction position for the blank sheet 11 by the second suction cup 34 of the sheet transfer means 33 is greatly separated vertically from the suction position for the blank sheet 11 by the first suction cup 18 of the auxiliary suction means 17. The separation interval of the leading blank sheet 11 from the succeeding blank sheet 11 at the suction position by the second suction cup 34 arranged corresponding to the lower part (lower end side) of the blank sheet 11 is as described above. It is getting smaller. Therefore, when the second suction cup 34 comes into contact, the blank sheet 11 is not greatly bent, and satisfactory suction is achieved and breakage of the sheet 11 is also prevented. Further, since the first suction cups 18 and 18 are moved back and forth by the variable speed motor 20, it is easy to synchronize with the operation of the sheet transfer means 33, and the sheet transfer means 33 takes out the blank sheet 11. And the preliminary separation of the blank sheet 11 by the auxiliary suction means 17 can be accurately matched, and the sheet can be taken out well.

  The variable speed motor 20 of the auxiliary suction means 17 is continuously rotated at a constant speed corresponding to the continuous operation of the sheet transfer means 33. The motor 20 is connected to the blank sheet with the first suction cup 18 at the head. By rotating at a non-uniform speed so that the operation when adsorbing 11 is delayed, sheet adsorption by the adsorption cup 18 can be performed satisfactorily. Further, by rotating the variable speed motor 20 at a non-uniform speed so that the operation of the first suction cup 18 when the second suction cup 34 of the sheet transfer means 33 sucks the leading blank sheet 11 is delayed, The leading blank sheet 11 can be favorably attracted by the second suction cup 34. The variable speed motor 20 may be intermittently rotated in correspondence with the removal of the blank sheet 11.

  The take-out portion 35 that sucks and holds the lower end side of the leading blank sheet 11 moves upward while being separated from the take-out port 12a, so that the lower end portion of the leading blank sheet 11 is rolled upward. It is separated from the lower end of the blank sheet 11. At this time, the notches of the shutters 16 and 16 rotated corresponding to the operation of the sheet transfer means 33 arrive at the separation position corresponding to the lower edge of the leading blank sheet 11, and the blank sheet 11 is acceptable. In addition, the lower end side corner portion of the subsequent blank sheet 11 is supported by the shutters 16 and 16 that continue to rotate, and the leading blank sheet 11 is reliably separated from the subsequent blank sheet 11.

  The take-out portion 35 of the sheet transfer means 33 moves downward, and accordingly, the blank sheet 11 taken out from the sheet magazine 12 is transferred downward. At this time, since the upper end side of the leading blank sheet 11 is already separated from the upper end side of the succeeding blank sheet 11 by the auxiliary suction means 17, the leading blank sheet 11 is smoothly taken out. Further, since the movement trajectory of the blank sheet 11 taken out by the sheet transfer means 33 does not interfere with the auxiliary suction means 17, it is not necessary to move the auxiliary suction means 17 to a position where it does not interfere with the sheet 11 when taking out the sheet. The configuration can be simplified.

  When the take-out portion 35 of the sheet transfer means 33 arrives at a predetermined position, the blank sheet 11 is transferred to the case transport conveyor 36 by releasing the suction of the blank sheet 11 by the second suction cup 34. The blank sheet 11 delivered to the case transporting conveyor 36 is transported to the downstream side in a state of being folded into a U-shape that opens upward.

  That is, in the auxiliary separating apparatus of the embodiment, the suction position of the second suction cup 34 with respect to the blank sheet 11 in the sheet transfer means 33 for taking out the blank sheet 11 from the sheet magazine 12, and the blank sheet 11 as a subsequent blank sheet 11 in advance. Since the suction position of the first suction cup 18 with respect to the blank sheet 11 in the auxiliary suction means 17 separated from the upper and lower ends is different from the upper and lower ends, breakage of the blank sheet 11 by the second suction cup 34 is prevented. The separation amount of the sheet separation by the auxiliary adsorption means 17 can be increased while enabling good adsorption and holding, and air can easily enter the gap formed between the sheets, so that the leading blank sheet 11 is separated. It can be performed well.

  When the size of the blank sheet 11 is changed, the base 22 is moved up and down with respect to the machine frame 21 (see FIG. 1), and the first suction cup 18, This can be accommodated by adjusting the height position of 18 to a position suitable for the sheet size.
