Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing paper cutter stacker device, and more particularly to a printing paper cutter stacker device that sequentially receives and stacks printing papers cut and discharged by a cutter unit mounted on a printer.

A conventional printing paper cutter stacker device sequentially receives and stacks labels, tags, and other printing papers that have been printed and cut into a single-leaf form.
In particular, when printing and stacking on a printing sheet in a predetermined order, the stacking order differs depending on the configuration of the cutter stacker device.
For example, FIG. 4 is a schematic side view of a descending stacker 1, and the stacker table 2 descends downward as the cut single-sheet printing paper 3 is supplied. The printing paper 3 is sequentially laminated.
There is a printing surface 4 (represented by dots in the figure) on the surface of the printing paper 3, and the order of printing and stacking is represented by numbers with parentheses beside the printing surface 4.

In the descending order type stacker 1 having such a configuration, the stacker table 2 is sequentially lowered downward when the printing paper 3 is stacked on the stacker 1, so that even a large printing paper 3 or a large amount of printing paper 3 is used. Even in the case of stacking, since only the weight of the printing paper 3 to be stacked is passively received, the driving load of the stacker 1 itself is small, and the structure is relatively simple and simple. be able to.
However, for example, when performing printing of contents requiring serial number printing or other serial number management, the printing paper 3 on which a lower number is printed is located on the lower layer side and increases upward in the order of the numbers. Therefore, in the state where the stacking is completed, the stacking state of the printing paper 3 taken out from the stacker 1 is in reverse order from the top to the bottom (descending order, that is, from a higher number to a lower number). There is a problem that handling after taking out from the stacker 1 is inconvenient.

FIG. 5 is a schematic side view of an ascending order type stacker 5. This stacker 5 has its stacker table 6 fixed at a predetermined level position, and the cut single-sheet printing paper 3 is supplied. At the same time, the next printing paper 3 is pushed into the lower layer side of the printing paper 3 previously laminated, the whole is pushed upward, and the paper is sequentially laminated.
As in FIG. 4, there is a printing surface 4 (represented by dots in the figure) on the surface of the printing paper 3, and the order of printing and stacking is represented by numbers in parentheses beside the printing surface 4. ing.

In the ascending order stacker 5 having such a configuration, the printing paper 3 on which a lower number is printed is positioned on the upper layer side and increases in the order of the numbers upward. The stacked state of the printed paper 3 taken out is in the normal order from the top to the bottom (ascending order, that is, from a smaller number to a larger number). However, when stacking the printing paper 3 on the ascending stacker 5, it is necessary to positively push up the weight of the entire printing paper 3 to be stacked while the stacker table 6 remains fixed. For this reason, the stacker 5 itself has a large driving load. In particular, when a large number of printing papers 3 or a large amount of printing papers 3 are stacked, the structure is relatively heavy. There is a problem of quantification or complexity.
Furthermore, in order to perform ascending stacking, it is necessary to synchronize the printing unit with the cutting unit and the stacking unit, and therefore it is necessary to integrate an electrical control system between them. There is also a problem of lack of versatility.

    It should be noted that both the descending descending stacker 1 and the ascending ascending stacker 5 are arranged in a straight line from the printing part to the cutting part and the laminated part, and therefore have a particularly large width or pitch. When the printing sheets 3 are to be stacked, there is a problem that a large installation space is required.

JP 2003-40509 A

    The present invention has been considered in view of the above problems, and it is an object of the present invention to provide a printing paper cutter stacker device capable of stacking printing papers with a small driving load without increasing the weight or complexity of the structure. Let it be an issue.

    In addition, the present invention provides a printing paper cutter stacker device that can obtain stacked printing papers in ascending order of numbers even when the stacker table is sequentially lowered downward like a descending order stacker. Is an issue.

    In addition, the present invention is for printing paper that enables large-capacity stacking that can reduce the driving load and realize an ascending stacking state even when the printing paper is large or when a large amount of printing paper is stacked. It is an object to provide a cutter stacker device.

    Another object of the present invention is to provide a printing paper cutter stacker device that can stack a large amount of large printing paper even if the installation space of the stacker itself is reduced.

    That is, the present invention provides a three-dimensional arrangement of the cutting section and the stacking section from the printing section, flips the printed printing paper upside down, stacks it in this inverted state, and turns the stacked printing paper that has been taken out upside down. If the paper is turned upside down, the printing paper in the state of being printed in order from the top can be obtained sequentially. The belt-like printing paper printed in the printing section is cut at a predetermined pitch by the cutting section, and this cutting is performed. A printing paper cutter stacker device for laminating single-sheet printing paper, provided between the printing unit and the cutting unit, and a reversing unit capable of turning the printing paper upside down, and downstream of the cutting unit A printing paper cutter stacker apparatus, comprising: a stacking unit that is provided on a side and stacks the cut printing paper.

    The reversing unit can have a buffer arm that can swing around a rotation shaft and can bypass the printing paper from the printing unit to the cutting unit.

    The reversing part may have a guide plate having an arcuate cross section that allows the printing paper to be detoured from the printing part to the cutting part.

    The stacking unit may have a stacker table that can be lowered downward as the printing sheets are stacked.

    The laminated portion can be provided on the lower layer side than the printing portion.

In the printing paper cutter stacker device according to the present invention, the printing paper printed by the printing unit is turned upside down by the reversing unit before reaching the cutting unit, so that the stacking unit such as a stacker table is turned upside down. Therefore, the stacked printing sheets have a lower number printed on the lower layer side, and a larger number is printed on the upper layer.
Therefore, when the printing paper is taken out from the stacking portion in the stacked state, and the entire printing paper in the stacked state is turned upside down, the lowest numbered printing paper is positioned on the uppermost layer, and the numbers are sequentially assigned downward. It is possible to handle printing paper in an increased state, that is, in an ascending order.
Thus, the cut printing paper can be received in sequence while the stacker table or the like in the stacking part descends and can be easily stacked, and only the next printing paper is placed on the stacked printing paper. Unlike the configuration in which the next printing paper is pushed into the lowermost layer of the stacked printing paper, the driving load can be reduced and the configuration can be simplified.
In particular, it is possible to save the entire installation space by adopting a three-dimensional structure in which the laminated portion is provided on the lower layer side from the printing portion.

    In the present invention, the belt-shaped printing paper is reversed and turned upside down in the reversing section and cut and stacked, so that the printing paper that can be printed in order can be obtained in order. A cutter stacker device was realized.

Next, a printer 10 equipped with a printing paper cutter stacker device according to a first embodiment of the present invention will be described with reference to FIGS. However, the same parts as those in FIGS. 4 and 5 are denoted by the same reference numerals, and detailed description thereof will be omitted.
FIG. 1 is a side view of the printer 10. The printer 10 includes a three-layer frame portion (a first frame portion 11, a second frame portion 12, a third frame portion 13), and a caster roller 14. And a paper supply unit 15, a printing unit 16, a printing paper cutter stacker device 17, and a front door 18 that can be opened and closed for taking out printing paper.
The printing paper cutter stacker device 17 according to the present invention includes a reversing unit 19, a cutting unit 20, and a stacking unit 21.

    The first frame portion 11 is provided with a caster roller 14, a front door 18, and a laminated portion 21.

    The second frame portion 12 is provided with a cutting portion 20 and can be provided with a placement and supply portion 22 for fan-hold type printing paper 3. The printing paper 3 can be supplied to the printing unit 16 from the placement supply unit 22.

    The third frame unit 13 is provided with a paper supply unit 15, a printing unit 16, and a reversing unit 19, and from the third frame unit 13 to the second frame unit 12, the left side in FIG. The reversing unit 19 and the cutting unit 20 are configured to be positioned in the forward and downward direction of the sheet transport direction.

    The paper supply unit 15 holds the belt-like print paper 3 in a roll shape, and can feed the print paper 3 in a belt shape toward the print unit 16.

    The printing unit 16 is a printer unit of an arbitrary printing method for printing predetermined information on the surface of the printing paper 3 (printing surface 4, upper side in the drawing in the drawing 16). Any other printing method can be used. In the illustrated example, the printer unit is a thermal transfer printing method.

The reversing unit 19 is provided between the printing unit 16 and the cutting unit 20 and is capable of reversing the printing paper 3 from front to back, and has a buffer arm 23 that contacts the back surface of the printing paper 3.
The buffer arm 23 can swing around the rotation shaft 24, and a spring 25 is provided at a portion of the rotation shaft 24 to urge the buffer arm 23 around the rotation shaft 24 in the clockwise direction in the figure. The buffer arm 23 urges the printing paper 3 in a direction that greatly sags, so that the printing paper 3 can be detoured from the printing unit 16 to the cutting unit 20 through a substantially semicircular or triangular detour 26.
By the slack over the predetermined length in the transfer direction of the printing paper 3 by the buffer arm 23 in the forward direction and the downward direction (hanging down from the third frame portion 13 toward the second frame portion 12), the cutting portion 20 and the printing portion 16 are separated. Although the difference in operating speed (generally, the processing speed in the cutting unit 20 is faster) can be absorbed, the operation control or adjustment system between the printing unit 16 and the cutting unit 20 is arbitrary. For example, it can be controlled to stop the transfer of the printing paper 3 each time the printing paper 3 is cut by the cutting unit 20, or the cutting unit 20 can cut the printing paper 3 while transferring the printing paper 3. When the buffer arm 23 rotates counterclockwise around the rotation shaft 24 as the processing of the printing paper 3 proceeds, the cutting at the cutting unit 20 is temporarily stopped and the printing paper from the printing unit 16 is printed. It is also possible to control so that the cutting process is resumed after waiting for the printing process 3, that is, after the buffer arm 23 is returned to the limit in the clockwise direction by the biasing force of the spring 25.

The cutting unit 20 cuts the strip-shaped printing paper 3 printed by the printing unit 16 at a predetermined pitch in the width direction to form a single-leaf printing paper 3, together with a plurality of transfer rollers 27 and sensors 28, a cutter 29, the single-sheet printing paper 3 cut from the discharge roller 30 can be supplied to the stacking unit 21.
In addition, the method of the cutter 29 is arbitrary, such as a rotary method. A type that cuts the printing paper 3 along with the transfer of the printing paper 3 or a type that stops the transfer of the printing paper 3 at the time of cutting can be adopted. is there.

The stacking unit 21 is provided on the downstream side of the reversing unit 19 and sequentially stacks the cut single-leaf printing paper 3. The stacking unit 21 is provided on the lower layer side of the printing unit 16, the reversing unit 19, and the cutting unit 20. It is.
The stacked unit 21 includes a stacker table 31, a lifting endless wire 33 wound around a pair of pulleys 32, a lifting drive motor 34, and a pitch regulating mechanism 35.

    The stacker table 31 is one in which the printing paper 3 guided from the pair of discharge rollers 30 to the inside of the stacking unit 31 is sequentially stacked on the stacking surface 31A from above, and is fixed to the lifting endless wire 33 at the mounting unit 31B. As the elevating endless wire 33 is driven by the elevating drive motor 34, the elevating endless wire 33 moves up and down in the drawing (refer to the one-dot chain line, solid line, and virtual line in FIG. 1). That is, the stacker table 31 can be lowered downward as the printing paper 3 is stacked.

The pitch regulating mechanism 35 is capable of adjusting the position in the pitch direction independently of the stacker table 31 according to the pitch dimension of the printing paper 3 (the dimension in the left-right direction in FIG. 1). A position adjusting dial knob 37, a wire 38 and a spring 39, a guide shaft 40, and a pair of pulleys 41 are provided.
The print sheets 3 are sequentially stacked in a stack space 42 formed by the stack surface 31A of the stacker table 31, the control surface 36A of the pitch control plate 36, and the inner wall surface 18A of the front door 18.
The pitch regulating plate 36 regulates the leading end portion of the printing paper 3 fed from the discharge roller 30 by its regulating surface 36A, and can be moved in the pitch direction of the printing paper 3 so that the pitch regulating plate 36 is independent of the stacker table 31. The position can be adjusted in the direction.
That is, the wire 38 is stretched around the base portion 36B of the pitch restricting plate 36 and the pair of pulleys 41 with a predetermined tension by the spring 39, and the position adjusting dial knob 37 is rotated in the forward and reverse directions to thereby rotate the pulley. The pitch regulating plate 36 (base portion 36B) can be moved and adjusted along the pair of left and right guide shafts 40 by rotating 41 and moving the wire 38 in the forward and reverse directions.

In the printer 10 and the printing paper cutter stacker device 17 configured as described above, the belt-shaped printing paper 3 supplied from the paper supply unit 15 or the placement supply unit 22 is predetermined on the surface (printing surface 4) side of the printing unit 16. The information is printed, and the reversing unit 19 bypasses the detour 26 and reaches the cutting unit 20 to be cut at a predetermined pitch.
The print surface 4 (front surface) of the printing paper 3 is reversed from the upper side to the lower side in the drawing and cut at the cutting unit 20 during the detouring in the detour circuit 26, that is, in a state where the front and back sides are completely reversed, that is, printing With the surface 4 facing the stacking surface 31A of the stacker table 31 (with the back surface of the printing paper 3 facing upward), the stacking space 42 of the stacking unit 21 is sequentially stacked on the stacking surface 31A of the stacker table 31 from above. Go.

    FIG. 2 is a schematic side view of the lamination space 42 showing the lamination state of the printing paper 3. In the lamination space 42, the printing paper 3 starts from a young number with its printing surface 4 facing down in the drawing. The layers are sequentially stacked. Similar to FIGS. 4 and 5, the order of printing and stacking is indicated by numbers with parentheses beside the printing surface 4.

Thus, when the stacking in the stacking portion 21 is finished, the front door 18 is opened, the stacked printing paper 3 is taken out from the stacking space 42, and the entire printing paper 3 is turned upside down as it is, the upper side is young. The stacking state of the printing sheets 3 can be obtained in the order in which the numbers are located and the numbers are sequentially increased downward, and the handling thereof can be made convenient.
Moreover, since the stacker table 31 only receives the printing paper 3 that naturally falls by its own weight from the upper side thereof onto the laminated surface 31A, it only needs to be lowered by the lifting drive motor 34, the pulley 32, and the lifting endless wire 33. The driving load of the entire printing paper cutter stacker device 17 can be kept small, the overall configuration can be simplified, and the paper supply unit 15, the printing unit 16, the reversing unit 19, the cutting unit 20 and the stacking unit can be simplified. Since each part such as 21 is incorporated as a three-dimensional structure by the first frame part 11, the second frame part 12, the third frame part 13, and the like, a large planar installation space is not required.

In the present invention, any configuration other than the buffer arm 23 can be adopted as a configuration for bypassing the printing paper 3.
For example, FIG. 3 is a schematic side view of a main part of a printer 50 equipped with a printing paper cutter stacker device according to a second embodiment of the present invention. As the inversion part 52, a guide plate 53 having an arc cross section is provided.

    The guide plate 53 can bypass the printing paper 3 from the printing unit 16 to the cutting unit 20 to the bypass 54, and the printing paper 3 passes through the bypass 54 and is cut by the cutting unit 20. The front and back surfaces of the laminated space 42 are reversed and are laminated in the same manner as in the case of the printing paper cutter stacker device 17 (FIGS. 1 and 2) described above.

    As an operation control or adjustment system between the printing unit 16 and the cutting unit 20, it is desirable to control so that the transfer of the printing paper 3 is stopped every time the printing paper 3 is cut by the cutting unit 20.

Also in the printer 50 and the printing paper cutter stacker device 51 configured as described above, the printing paper 3 is guided in an arc shape by the guide plate 53 of the reversing unit 52 so that the front and back thereof can be reversed, and the cutting unit 20 and the stacking unit 21. Therefore, if the printing paper 3 is taken out from the laminated space 42 and turned upside down, a laminate of the printing paper 3 printed in the order of young numbers can be obtained, and the subsequent handling can be facilitated. .
