Description

  The present invention relates to a counting division conveying apparatus for producing a predetermined number of bundles from a fractional bundle to a standard bundle in a state in which a newspaper or other printed matter supplied from a high-speed rotary printing press is adapted to the printed matter without impeding its flow. In particular, printed fold sorting means for creating a small bundle of printed materials by performing counting classification, a new control means for sorting plates, and the packaging when dropping folds on a receiving plate for creating small bundles The present invention relates to a novel structure of a small bundle stacking table for signatures having a changing means and a packing shape changing means on a half turntable. Note that in this specification, an arbitrary number of newspapers or other printed matter folded is referred to as a “folding”.

Conventionally, for example, in a known counting section conveying apparatus for creating a small bundle of printed materials such as described in Japanese Patent Publication No. 57-28664, an eclectic printed material such as newspaper is sent in a shifted state. It is transported in a state of being sandwiched from both sides by a belt composed of a transport roller group and a spring strip stretched over the transport roller group. Then, by providing a counter in the middle of the transfer path, the number of copies of the folded and folded signature is counted, and according to the set number of copies and the count number of the coefficient unit, the deviation and piled signature is transferred. After driving the section plate that temporarily stops and pulling out the last set of signatures in the meantime, and after receiving the fixed number of signatures on the support plate, for example, binding in the next process It was transferred to the machine. In such a transport apparatus, in order to bundle several ordinary folded small bundles, for example, a bundle with a guide is provided that stores the folded small bundles alternately in a 180 ° direction. A turntable is provided.
Japanese Patent Publication No.57-28664

  However, in such a conventionally used counting section conveying apparatus, firstly, the section plate for temporarily capping the fold is driven independently, so that its position is set to the page or thickness of the fold. It was difficult to combine. Secondly, there are a drawing roller for pulling out the lower signature to enter the small bundle from the bottom of the damped signature, and a drawing roller for pulling out the whole signature on the receiving plate from the end of the transfer section. Since each was provided separately, the number of parts was large. Thirdly, it is difficult to change the packaging according to the thickness of the signature for dropping the signature on the receiving plate.

  Fourth, when a certain number of printed signatures are dropped from the receiving plate into the turntable frame, the end of the small signature bundle comes into contact with the inner surface of the signature plate, The upper and lower folds are shifted to the left and right, so that each time the turntable is turned in half and a small bundle of folds is sequentially inserted, the left and right ends thereof compete along the inner side surface of the enclosure plate, for example, as shown in FIG. The both ends gradually moved greatly from the center, and when they were bound together, the above-displaced portion was bent, and for example, there was a drawback that the commercial value of newspaper or the like was lost. The present invention solves such various problems all at once, smoothly divides and counts the signatures, transports and prevents the auction due to the stacking of the ends of the small bundles of the signatures, a new sorting means, and conveyance Provided is a sorting and conveying apparatus provided with roller means, a turntable and the like.

  The present invention provides a laser sensor that is provided with means for conveying a signature such as a newspaper in a deviated manner, and a step for changing the direction in which the signature is transferred by crossing the transfer direction planes in a conveyance path for carrying the error in a superimposed manner. On the downstream side near the step portion and substantially orthogonal to the downstream transfer surface, and the elongate drawing roller, the section plate, the discharge roller at the downstream transfer surface end portion, and the receiving plate means on the downstream side thereof In the signature sorting and conveying apparatus having a semi-swivel cradle, the drawing roller has a divided structure, and the drawing roller has a structure in which the sorting plate enters a recess in a substantially central portion in the width direction. It is a fold sorting transporting device characterized in that it also serves as a fold pulling roller from the transfer surface.

  The effect of the first characteristic configuration of the present invention is that, when the main arm is driven for transporting the clogged pool after completion of the sorting for each small bundle, the pages of the printed material to be sorted and transported are built. It is possible to achieve a structure in which the position of the end of the claw section from the upper surface of the conveying fold is constant regardless of the state of the paper row. The effect of the second characteristic configuration is that the drawing roller and the drawing roller which are separately required in the conventional apparatus can be used in common, and the number of parts can be reduced and the maintenance can be simplified. The third characteristic configuration automatically changes the loading form on the receiving plate according to the page structure or paper quality of the folds that are conveyed separately, so that the accurate alignment of the folding on the receiving plate is always performed. It is to secure. In addition, the fourth characteristic configuration prevents fold-up folding caused by misalignment of the upper surface crease due to a small number of pages, etc., when a plurality of small bundles of folds are stacked on a semi-rotating cradle (turntable). In addition, it is possible to eliminate a decrease in commercial value due to bending of the edge of the newspaper. Further, in combination with the accurate count sorting operation by the arrangement of the laser sensor and the operation of the air nozzle which is the basic configuration of the present invention, it is possible to obtain a smooth printed material sorting and conveying device without malfunction.

An embodiment of the present invention will be described with respect to a newspaper bunch creation machine.
FIG. 1 shows an outline of a newspaper bundle making machine using the apparatus of the present invention. Newspaper folds, which are printed materials that are printed at high speed and are constructed in arbitrary pages, are sequentially shifted and overlapped, and an introduction drum 1 is shown. Accepted by. In this case, if the eclectic is a newspaper, for example, there may be 32 pages, 16 pages, or a regular evening publication with 8 pages.
Here, the wire cord 2 is wound between the introduction drum 1 and the paper discharge roller 3, and similarly, the wire cord 2 is also wound around the rollers R1, R2 and the main drive roller RM to form the belt portion V1. These two sets of wire cords each constitute a feed belt, and a large number of newspaper signatures are continuously transferred at a high speed while being sandwiched between the pair of belts.

  On the other hand, a belt composed of a group of wire cords 2 is wound between the main drive roller RM and the presser roller 5 to form a belt portion V2, and the belt portion V1 and the belt portion V2 form an obtuse angle. ing. A belt portion V3 comprising a group of wire cords 2 wound around a step roller 4 and a discharge roller 8 as shown in the figure is provided at a position facing the belt portion V2, and the press roller 5 is The belt portion V3 is pressed at the end portion of the belt portion V2 and slightly downstream of the step roller 4 of the belt portion V3.

A pull-out roller 7 is provided at the position of the discharge roller 8 so as to oppose it, and the pair of rollers 7 and 8 are normally pulled out while holding the folded folds with a constant pressure, as will be described later. After the sorting operation, it has the function of forcibly pulling out and transporting the downstream newspaper fold to be entered into the previous bundle from the folds which are stopped, stopped and overlapped.
In this drawing roller portion, in the conventional apparatus, a means for blocking is arranged at a substantially intermediate position of the belt portion V3, and a drawing roller is provided at that portion, so that a separate portion is provided between the discharge roller 8 and the means for blocking. I needed a roller to pull out the eclectic. However, in the present invention, the division claw 9 (the division claw may be a division plate, and the terminology of the division claw is used for such a member in the embodiment) which is a blocking means in the present invention. It is characterized in that the conventional drawing roller and the drawing roller 7 are combined.

  In the drawing, a main receiving plate 13 and a lower receiving plate 14 are sequentially provided on the lower downstream side of the discharge roller 8, and each of them temporarily receives a required number of newspaper folds. Each of the receiving plates 13 and 14 is configured by a pair of receiving plate members (details are omitted) that are opened and closed left and right as they are dropped into a guide opening / closing enclosure plate 18 provided at 40 (details will be described later). . A paper aligning plate indicated by reference numeral 12 is swingably supported in front of the main receiving plate 13, and is divided into an arbitrary number of counts by an arm pivotally supported by the rotating plate, for example, on the main receiving plate. It pushes and aligns the paper ends of the stacked eclectic bundles.

  2 and 3 show a state in which the belt portions V1 and V2 for sequentially transferring the signatures shifted and overlapped at the counting portion intersect each other at an obtuse angle to form a stepped portion 20. FIG. In other words, each of the signatures A1 to An of the newspaper that are sequentially inserted after being shifted and stacked is sandwiched by the introduction drum 1 with respect to the belt portion V1 at the left end portion of FIG. 2, and proceeds in the direction of the main drive roller RM according to the belt portion V1. To do.

On the other hand, the wire cord 2 is wound around the main drive roller RM and the presser roller 5 to form a belt portion V2, and each belt portion V1, V2 forms a step with an angle of about 135 °, for example. Wire cords 2 constituting V1 and V2 are wound around the main drive roller RM, respectively. Therefore, the direction of the tip of each signature An that is transferred in the belt direction by the belt portion V1 is changed by the step portion 20 that intersects the belt portion V2 in the vicinity of the outer periphery of the main drive roller RM. Guided.
Here, in the embodiment, the angle at which the belt portion V1 and the belt portion V2 intersect is about 135 °, but this angle can be selected within a range of about 110 ° to 150 °.

A laser counter (hereinafter referred to as a laser sensor in the specification) 11 is fixed on a bracket attached to a base frame (not shown), and its irradiation position is slightly downstream of the belt crossing position, that is, the step portion 20. It is set.
Further, as is apparent from the figure, the laser sensor 11 is installed in a state substantially orthogonal to the belt portion V2 on the downstream side of the step portion 20. This is set so as to obtain the best reflection surface in relation to the irradiation direction of the laser beam and the reflection surface that intersects with the irradiation direction. For example, the crossing angle of the belt portions V1 and V2 in the stepped portion is changed. Needless to say, it can be arbitrarily changed by the above. The configuration of the laser sensor 11 itself is of a known type, and may be of a type that detects and counts the tip of the signature by irradiating a laser beam and detecting the received light waveform of the reflected light. .

  In addition, the air nozzle 10 is installed with its tip directed near the intersection of the belt portions V1 and V2. Then, the air from the air nozzle 10 facilitates the direction change of the fold tip at the position where the tip end of each fold An is almost equal to the position where the belt portion V2 starts to change the direction, and is further bent. The paper surface of the bag is configured so as to continuously press the surface of the signature so as not to cause vibration or displacement in the laser irradiation direction of the laser sensor 11.

2 and 3 have the same member configuration including the relationship between the drawing roller arm and the segment pawl support arm, which is the first characteristic configuration of the present invention. However, FIG. FIG. 3 similarly shows the state in which the division claw 9 is lowered.
In particular, in FIG. 2, one end of a substantially rectangular main arm 30 that is a drawing roller arm is supported so as to be swingable on the same axis as the rotation support shaft of the main drive roller RM. Two intermediate rollers R3 and R4 are supported at the digging portion, and a drawing roller 7 is supported at the tip of the main arm 30. The drawing roller 7 is driven by being wound around the belt made of the wire cord 2 together with the main drive roller RM via the two intermediate rollers R3 and R4.

  In the damming state shown in FIG. 3, the subsequent signatures that are successively fed are sandwiched between the belt portion V3 and the presser roller 5 and further moved to the side by the kanzashi roller 6. The A support plate 19 is swingably provided on the back surface of the belt portion V3, and a plurality of stacked signatures are supported by the cylinder C3 together with the belt portion V3. Therefore, during the processing of the preceding count-sorted signature bundle on the receiving plate, the subsequent signature is made to wait at this position.

  As shown in FIG. 4 in an enlarged manner, the first and second characteristic configurations of the present invention are the support and drive mechanism for the main arm 30 that supports the drawing roller 7 and the segment claw support arm 31 that supports the segment claw 9. There is in point. That is, in the drawing, the main arm 30 that supports the drawing roller 7 and the segment claw support arm 31 that supports the segment claw 9 are both supported so as to be swingable about the rotation support shaft P of the main drive roller RM. .

  The attachment end of the drawing roller 7 on the main arm 30 is connected to a roller position adjusting cylinder C2 fixed on the support frame, and is folded and conveyed, for example, for newspapers, to the fixed position at the center of the discharge roller 8. When the soot is forcibly conveyed, or when the accumulated portion at the time of sorting passes, a conveyance path is opened by the cylinder C2 to facilitate passage. The drive setting of the cylinder C2 in this case is automatically performed in accordance with the page order command of the signature to be handled.

  The arm 31 for supporting the segment claw 9 and the bracket 32 for connecting them are integrated, and a segment claw operating cylinder C1 is provided at a substantially intermediate portion between the bracket 32 and the main arm 30 via attachment means. It has been. Therefore, when the cylinder C1 is actuated after the small bundle processing at the downstream end to raise the sorting claw 9, the main arm 30 is swung by driving the cylinder C2 in conjunction with the actuation signal of the cylinder C1, for example. The pulling roller 7 is moved, and a conveyance path through which a plurality of creases accumulated during the passage pass is opened. Basically, the main arm 30, the support arm 31, and the bracket 32 are connected to the cylinder C1. Therefore, the distance between the end of the division claw 9 and the upper surface of the newspaper that is the signature is always kept constant regardless of the page structure (that is, the signature thickness).

  Furthermore, in the present invention, the attachment position of the division claw 9 is set slightly upstream of the position where the protruding roller 8 and the drawing roller 7 which are the ends of the conveying belt portion of the signature are opposed. As a result, the position of the folds which are dammed up and temporarily stacked is the position upstream of the section claw 9 and slightly upstream of the drawing roller 7. For this purpose, a roller for pulling out the signature to be put into the previous bundle from the lower portion of the folded and folded signature required in the conventional apparatus, and separately for pulling and dropping the signature from the end of the conveyor belt portion. In the present invention, the roller can be shared by one of the drawing rollers 7.

FIGS. 5 and 6 show the relationship between the discharge roller 8 and the drawing roller 7 and the specific configuration of the discharge roller 8, which is the third characteristic configuration of the present invention.
As is apparent from the drawing, the discharge roller 8 is composed of a central roller portion 8C and left and right roller portions 8L and 8R.
As indicated by the same reference numerals in the drawings, the central roller portion 8C of the discharge roller 8 is rotatably supported by a pair of fixed shaft support plates 39, 39 attached to the frame, and the support position is unchanged. On the other hand, the left and right roller portions 8L and 8R are rotatably supported by cantilever support shafts 36 and 36 that are cantilevered by movable brackets 35 and 35, respectively. Each of the movable brackets 35 has arcuate guide slits 37, 37, and two guide pins 38, 38 are inserted through the guide slits. Therefore, each movable bracket 35 is movable as the guide slit 37 slides along the two guide pins 38, 38.

  The movable brackets 35 and 35 are configured so as to be driven by the load change cylinders C4 and C4 fixed to the frame. Therefore, as is clear from a comparison of FIGS. 5 and 6, the package form at the time of discharge, that is, the degree of curvature of the fold, can be arbitrarily changed by, for example, page building of the folds An that are separately conveyed. Therefore, for example, in the case of a thick signature such as 32 pages, it is discharged in a relatively flat package shape as shown in FIG. 5 and dropped on the receiving plates 13 and 14 on the lower downstream side. It can be dropped while maintaining the package shape at the time of discharge.

  On the other hand, in the case of a thin fold such as 8 pages, for example, if it is ejected in such a flat state, problems such as deformation of the packing shape and change of the dropping direction occur during dropping, as shown in FIG. The load-changing cylinders C4 and C4 are driven to change the inclination of the cantilever shafts 36 and 36 of the left and right rollers 8L and 8R, thereby increasing the degree of curvature of the crease An as shown in FIG. Prevents deformation of the figure and guarantees accurate fall on the support plate.

FIG. 7 is a plan view and a side view showing the structure of the turntable 40 constituting the fourth characteristic portion of the present invention and the horse back member 45 provided thereon.
A horse back member 45 is provided across the center of the turntable 40, and the member is flush with the table surface as shown in FIGS. 8 and 9, which will be described later, or a retracted position below the surface (see FIG. 8) or Any one of the protruding positions (see FIG. 9) can be selectively moved. As shown in the figure, for example, a horse back member 45 constituted by a pair of bars is supported by a main body portion of the turntable 40 so as to be vertically movable by two rods 44, and a lower portion of the rod 44 is fixed to a support disk 46. Yes.

  As is apparent from FIGS. 8 and 9, the support disk 46 is supported by rollers 48 and 48 at the front ends of a pair of levers 47 and 47 that are swung by a pair of cylinders C5 and C5 provided on the frame. When necessary, regardless of the rotational position of the support disk 46, by operating the pair of cylinders C5, C5, the horse back member 45 is moved via the swing levers 47, 47 and the rods 44, 44 to the surface of the turntable. To a projecting position or a retracted position.

  FIG. 8 shows the stacking of small bundles of signatures that are sequentially dropped onto the turntable 40 in a state where the mechanism related to the turntable 40 and the horse back member 45 are in the retracted position. First, the turntable 40 itself is configured to repeat a half turn of 180 degrees simultaneously with the fall of the small bundle of signatures by a drive device schematically indicated by reference numeral 41. By the way, as apparent in the figure, when the arbitrary number of eclectic small bundles B1 to Bn sequentially fall into the guide plate frame of the turntable 40, the end portions of the small bundles contact the guide plate frame, The folds above each small bundle are biased to the left and right of the drawing sheet, and the degree of bias gradually increases each time the turntable is turned halfway.

  For example, as shown in Bn in the drawing, when several bundles in a state where the upper part of the folded small bundle is bent and displaced are bundled as they are in the next process, the folded paper pieces of the small bundles protruding to the left and right are folded as they are to the side. Since they are bundled, a large number of creases are produced at the ends of the signatures. Such a phenomenon is particularly prominent when the thickness of the eclectic small bundle is small and the number of bundles, that is, the number of times the small bundle is dropped and stacked is large.

  Therefore, in the present invention, the back member 45 of the horse is fixed at the protruding position as shown in FIG. That is, in FIG. 9, the pair of cylinders C5 and C5 are actuated as necessary to tilt and move the swing lever 47 and the roller 48 upward. As a result, the support disk 46 moves the back member 45 of the horse to the protruding position as shown in the figure via the rod 44 (see FIG. 7).

  In such a state, the small bundle of eclipses successively dropped is supported by the horse's back member 45 at the center thereof, and is bent lightly in a convex shape, and both end portions of the bundle B1 are illustrated. It is surely placed in the board frame. When the small bundles are gradually stacked in this way, the bundle is just leveled around the intermediate number of parts, and when the small bundles are further stacked, the light curve starts to be concavely lightened. However, as shown in FIG. 8, the stacking accommodation of the specified number of small bundles B1 to Bn is completed before the end of the upper portion of the small bundle is protruded, and further, the horizontal state at the substantially middle position of the bundle number is moved up and down. Coupled with the symmetrical stacking, there are no left and right bent portions even when bound.

It is a principal part schematic of the signature division conveyance apparatus which concerns on this invention. FIG. 2 is an enlarged explanatory view of a counting device portion in FIG. 1. It is explanatory drawing which shows the other operation state of the part similar to FIG. FIG. 3 is a partially enlarged view of FIG. 2 showing the arrangement and operation states of a division claw, a drawing roller, a discharge roller, and the like. It is a front view which shows one operation | movement form of a discharge roller. It is a front view which tightens the other operation form of a discharge roller. It is the top view and front sectional drawing of a turntable. It is explanatory drawing of the stacking state of the small bundle of signatures on a turntable.
