Description

The present invention relates to a paper transfer device that takes out stacked sheets for each sheet and transfers them to a predetermined position.

In recent years, for example, there is a business of enclosing paper such as pamphlets and contracts in an envelope, and there is also an automatic device, but for lots where the total number of sheets is extremely small, the device setting time for the device operating time increases and the cost increases. The reality is that it is done manually because it is not worth it. Since such work requires mistakes and education, automation is desired, and it is necessary to reliably take out only the paper at the highest position of the stacked papers at that time.

Conventionally, various techniques for taking out stacked papers and the like for each sheet have been known. For example, in Patent Document 1, two suction heads are used to suck two places on the top sheet, and then the two places are brought closer to each other while being sucked to make the sucked sheet convex. A technique is described in which only the top sheet is adsorbed by returning the second and subsequent sheets to their original state due to the force of returning to.

Japanese Unexamined Patent Publication No. 2010-407334

However, the technique described in Patent Document 1 is that the paper is breathable and the suction head sucks the two or three sheets of paper stacked together with the paper at the highest position, so that the paper at the highest position is sucked. There is a problem that it is difficult to adsorb only the paper, and for that reason it is considered to blow air to make a sheet, but there is a problem that the device becomes large-scale due to the additional configuration for that purpose. ..

Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a paper transfer device for reliably transferring stacked sheets as sheets without using adsorption for paper holding.

In order to solve the above problem, the invention of claim 1 is a paper transfer device that holds the stacked papers for each sheet and moves them to a predetermined position, and is used as the topmost paper of the stacked papers. On the other hand, a paper upper surface pressing mechanism provided with a predetermined number of upper surface abutting bodies for pressing and holding the upper surface, and a paper upper surface pressing mechanism for reciprocating the paper upper surface pressing portion to the paper side, and an edge of the uppermost paper. It is provided with a paper-turning rotating body that is turned up from the local area to the inner center side by rotation, and is turned up by a paper-turning mechanism that moves the paper-turning rotating body with respect to the paper and the paper-turning rotating body. A lower surface abutting body is provided that is positioned by moving to the lower surface side of the paper, and the paper upper surface pressing portion is moved together with the paper onto the lower surface abutting body by the paper upper surface pressing mechanism, so that the paper upper surface pressing portion is together with the paper upper surface pressing portion. The paper lower surface pressing mechanism for holding the paper, and at least the paper upper surface pressing mechanism and the paper lower surface pressing mechanism for holding the uppermost paper by the upper surface contact body and the lower surface contact body are moved to a predetermined position. It is configured to have a transfer mechanism.

According to the invention of claim 1, a paper upper surface pressing portion provided with a predetermined number of upper surface abutting bodies in which the upper surface of the paper is reciprocated to the paper side of the paper upper surface pressing mechanism with respect to the uppermost paper of the stacked paper. The paper-turning rotating body of the paper-turning mechanism is turned up from the end region of the top-level paper to the inner center side by holding the presser, and the paper lower-side pressing mechanism moves the lower-side contact body to the lower surface of the paper. By moving the paper upper surface pressing portion together with the paper on the lower surface contact body by the paper upper surface pressing mechanism, the paper is held together with the paper upper surface pressing portion, and the held paper is moved to a predetermined position. By adopting the transfer configuration, the stacked sheets can be reliably held and transferred for each sheet without using a suction mechanism.

FIG. 1 shows a configuration explanatory view of the paper bottom pressing mechanism of FIG.

In FIG. 1, the paper transfer device 11 is roughly classified into a paper top pressing mechanism 12 described in detail in FIG. 2, a paper turning mechanism 13 detailed in FIG. 3, and a paper bottom pressing mechanism 14 detailed in FIG. The drive unit is fixed to the drive unit fixing plate 15. Then, the paper upper surface pressing mechanism 12, the paper turning mechanism 13 and the paper lower surface pressing mechanism 14 are integrally moved in the vertical direction H and the horizontal direction Y by a transfer mechanism (not shown). As the transfer mechanism, a three-dimensional work movement mechanism that has been known conventionally is sufficient.

The paper top surface pressing mechanism 12 is composed of a paper top surface pressing unit 21, a slide mechanism unit 22, and a slide drive unit 23. The paper upper surface pressing portion 21 is for abutting and holding the upper surface of the top-level paper of the stacked paper, which will be described later, and for moving the abutted paper onto the lower surface contact body 61, which will be described later. Is.

Specifically, as shown in FIG. 2A, for example, two upper surface contact bodies 31 and 32 are arranged at predetermined intervals, and a paper holding auxiliary portion 33 is arranged between the upper surface contact bodies 31 and 32. Will be done. For the upper surface contact bodies 31 and 32, for example, smooth silicone rubber is used. The lower surface of the paper holding auxiliary portion 33 is composed of a recess 33A, and the tip surface on the bank side thereof is located equal to or above the lower surface (paper contact surface) of the upper surface contact bodies 31 and 32.

The upper surface contact bodies 31 and 32 are fixed to the upper surface contact body fixing portions 31A and 32A, respectively, and the upper surface contact body fixing portions 31A and 32A are fixed to the connecting body 34 together with the paper holding auxiliary portion 33. A slide rod sliding portion 35 having through holes corresponding to the slide rods 43A and 43B, which will be described later, is mounted on the connecting body 34, and a belt engaging body fixing portion in which the belt engaging body 36 is located above the slide rod sliding portion 35. 36A is attached to the slide rod sliding portion 35. The belt engaging body 36 is formed with an uneven portion that engages with an uneven portion formed inside the drive belt 46, which will be described later.

The slide mechanism portion 22 of the paper upper surface pressing mechanism 12 reciprocates the paper upper surface pressing portion 21 toward the paper side (the horizontal direction X in FIG. 2C and the direction perpendicular to the horizontal direction Y in FIG. 1). It is something to make. Specifically, as shown in FIG. 2B, upper plate end portions 42A and 42B are provided below both end portions of the upper plate 41 according to the lengths of the slide rods 43A and 43B, and the upper plate ends Slide rods 43A and 43B are provided between the portions 42A and 42B. The slide rods 43A and 43B penetrate the through hole of the slide rod sliding portion 35 of the paper holding portion 21 and serve as a sliding guide. Further, the upper plate 41 is formed with an opening for engaging the belt engaging body 36 of the paper upper surface pressing portion 21 with the drive belt 46 described later and sliding the belt engaging body 36.

The slide drive unit 23 of the paper upper surface pressing mechanism 12 has a belt drive pulley 44A mounted on the shaft of the rotation drive unit 44 provided on the drive unit fixing plate 15, and the upper plate end portion of the upper plate 41. It is located above the 42B side. The belt drive pulley 44A is formed with an uneven portion that engages with an uneven portion formed inside the drive belt 46.

On the other hand, a rotary pulley fixing portion 45 is provided on the upper plate end portion 42A side of the upper plate 41, and the rotary pulley 45A is mounted on the shaft of the rotary pulley 45. The rotary pulley 45A is formed with an uneven portion that engages with an uneven portion formed inside the drive belt 46. A drive belt 46 having an uneven portion engaged with the belt drive pulley 44A and the rotary pulley 45A is suspended.

Then, as shown in FIG. 2 (C), the slide rods 43A and 43B of the slide mechanism portion 23 are placed in the through holes of the slide rod sliding portion 35 in the paper upper surface pressing portion 21 of the slide mechanism portion 22 of FIG. 2 (B). The belt engaging body 36 in the paper upper surface pressing portion 21 is penetrated and engaged with the inside of the drive belt 46 by matching the uneven portion, and the belt drive pulley 44A is rotated in the forward and reverse directions of the rotary drive portion 44. 21 rotates, and the paper upper surface pressing portion 21 slides on the slide rods 43A and 43B and is reciprocated in the above-mentioned horizontal direction X.

The paper-turning mechanism 13 of the paper transfer device 11 includes a paper-turning rotating body 51 that turns from the end region of the top-level paper to the inner center side by rotation, and the paper-turning rotating body 51 is attached to the paper. It is for moving against. Specifically, as shown in FIG. 3, the rotation drive unit 52 is fixed to the drive unit fixing plate 15, and a rotation transmission unit 53 having a predetermined length is attached to the rotation drive shaft 52A. A rotation drive unit 54 is attached to the other end of the rotation transmission unit 53. A paper-turning rotating body 51 is mounted on the rotating shaft of the rotating driving unit 54.

The paper-turning rotating body 51 is reciprocated in an arc shape between the initial position and the lowermost end via the rotation transmission portion 53 by the forward and reverse rotation A of the rotation driving unit 52, and is positioned at the lowermost end. Then, the position is adjusted so as to be substantially the same as the contact surface (lower surface) of the upper surface contact bodies 31 and 32 of the paper upper surface pressing portion 21. Further, the paper turning rotating body 51 is positioned so as to be tangential to the inner center side from the edge region of the paper with respect to the paper described later (see D in FIG. 6A), and the inner center is adjusted. It is rotated in the direction B that transmits the rotational force to the side.

The paper bottom surface pressing mechanism 14 of the paper transfer device 11 includes a bottom surface contact body 61 that is moved and positioned toward the bottom surface side of the paper that has been turned up by the paper turning rotating body 51. Specifically, as shown in FIG. 4A, the lower surface contact body rotation drive unit 62 is fixed to the drive unit fixing plate 15, and the rotation drive shaft 62A extends below the drive unit fixing plate 15. One end of a long plate-shaped lower surface contact body 61 is attached to the tip end portion thereof. In this case, the lower surface contact body 61 rotates in the horizontal direction due to the forward and reverse rotation C of the lower surface contact body rotation drive unit 62, and the direction D when positioned on the paper side to be held is the upper surface of the paper. The pressing portion 21 is rotated so as to coincide with the horizontal direction X, which is the moving direction of the pressing portion 21.

That is, when the lower surface contact body 61 is at a position corresponding to the horizontal direction X, which is the moving direction of the paper upper surface pressing portion 21, the paper upper surface pressing mechanism 12 is used to press the paper upper surface as shown in FIG. 4 (B). When the portion 21 is moved together with the paper abutting on the lower surface abutting body 61, the other end side of the lower surface abutting body 61 is allowed to enter the recess 33A of the paper holding auxiliary portion 33 of the paper upper surface pressing portion 21. Therefore, the paper is held together with the paper upper surface pressing portion 21.

Therefore, FIGS. 5 to 8 show explanatory views of paper transfer by the paper transfer device of the present invention. In addition, in FIG. 5A and FIGS. 6 to 8, the drawing is simplified, and the paper holding portion 21 (top contact body 31, 32, paper holding auxiliary portion 33), the paper turning rotating body 51, and the bottom surface contact are simplified. The operation will be described by showing only the contact body 61.

In FIG. 5A, with respect to the stacked paper 71, the paper top pressing mechanism 12 of the paper transfer device 11 aligns the moving direction X of the paper top pressing portion 21 with the pulling direction of the top paper 71A, and slides. The tip of the mechanical portion 22 is arranged so as to be positioned slightly above the inner side of the paper 71A. In the figure, the initial position of the paper upper surface pressing portion 21 is shown as a position that does not overlap with the paper 71A, but it may be located on the tip side of the slide mechanism portion 22 above the paper 71A.

Therefore, as shown in FIG. 5 (B), the paper top pressing portion 21 is slid upward (in the X direction) inside the paper 71A, and after the movement, the paper top pressing mechanism 12 (actually, the paper turning mechanism 13 and the paper) The lower surface pressing mechanism 14 (although omitted below) is moved downward (in the H direction) to bring the upper surface contact bodies 31 and 32 into contact with the upper surface of the paper 71A.

Subsequently, as shown in FIG. 6A, the paper turning rotating body 51 is rotated (B), and the rotating driving unit 52 of the paper turning mechanism 13 is driven to rotate the paper turning rotating body 51. (A) is brought into contact with the edge region of the paper 71A. At this time, the rotational force of the paper turning-up rotating body 51 is applied to the direction D on the inner center side of the paper 71A, and as shown in FIG. 6B, the edge region of the paper 71A begins to be turned. That is, by setting the direction of the rotational force of the paper-turning rotating body 51 to the direction D on the inner center side of the paper 71A, the paper-turning rotating body 51 can be turned up more reliably.

As shown in FIG. 7A, when the end region of the paper 71A is turned up, the end region becomes above the paper turning rotating body 51 due to the recovery reaction thereof, and the paper turning rotating body 51 Is in a state of entering the lower surface of the paper. Subsequently, as shown in FIG. 7 (B), the paper turning rotating body 51 is rotated (A) so as to return to the initial position and raised from the paper surface to secure a passage space for the lower surface contact body 61. At this time, the rotation of the lower surface contact body rotation drive unit 62 rotates the lower surface contact body 61 to the lower surface of the paper so that the position coincides with the horizontal direction X which is the movement direction of the paper upper surface pressing portion 21. ..

At this time, as shown in FIG. 7C, the end portion of the paper 71A turned up by the above-mentioned rotation of the paper-turning rotating body 51 returns to the lower side of the paper-turning rotating body 51. The paper-turning rotating body 51 is rotated (A) in the opposite direction to return to the initial position.

Subsequently, as shown in FIG. 8 (A), by sliding the paper upper surface pressing portion 21 together with the abutted paper 71A onto the lower surface contact body 61, the lower surface is as shown in FIG. 8 (B). By inserting the abutting body 61 into the recess 33A of the paper holding auxiliary portion 33 of the paper top pressing portion 21, the paper is held together with the paper top pressing portion 21.

That is, as shown in FIG. 8C, the upper surface of the paper 71A is in contact with the upper surface contact bodies 31 and 32 and the lower portion of the paper holding assisting portion 33, and the lower surface is between the upper surface contact bodies 31 and 32. It is brought into a holding state by being brought into contact with the lower surface abutting body 61, and in this state, it is transferred to a predetermined position by the above-mentioned moving mechanism (not shown).

As described above, the paper transfer device 11 of the present invention realizes that the upper surface contact bodies 31 and 32 correspond to the index finger and the middle finger of the human hand, and the lower surface contact body 61 corresponds to the thumb. That is, the upper surface of the uppermost paper 71A is pressed by the index finger and the middle finger (upper surface abutting bodies 31, 32), turned up by the paper turning rotating body 51, and the thumb (lower surface abutting body 61) is positioned on the lower surface of the paper. The structure is such that the thumb (bottom contact body 61) on the lower surface of the paper and the index finger and middle finger (top contact bodies 31, 32) on the upper surface of the paper hold the paper, so that the paper can be stacked without using a suction mechanism. The paper 71A can be reliably held and transferred for each sheet.

The paper transfer device of the present invention can be used in the industrial fields of taking out stacked papers, transferring them to the next process, and processing them, and using and selling the devices.
