DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention This invention is for updating printed matter such as newspapers that are printed in large quantities by a rotary printing press, folded, and conveyed with a certain pitch. The present invention relates to an apparatus that counts, sorts, and stacks based on transport information to create a required number of printed material stacks.

BACKGROUND ART The applicant has publicly known the device disclosed in Japanese Patent Laid-Open No. 63-82278 as this type of device, and this prior art has a lot in common with the embodiment of the present invention shown in the drawings. Therefore, the conventional technique will be described with reference to this embodiment.

A stacking unit 3 having a stacking member that counts printed materials P that are folded by a rotary printing press and is conveyed in a misaligned state by a counting member 5 and stacks them into a set number of small bundles, and then transports them to a falling position below. And a creating unit 4 for creating a stack of bundles from the small bundle printed matter transferred by the stacking member, said stacking member comprising a pair of roller chains 34, 34 'which constantly circulate between the vertical turning units, and a spring. A plurality of holding members 61 that have a pair of holding pieces 36 and 37 that engage with each roller chain 34 ′ by the force of 40, thereby moving together with the roller chain 34 ′, and swinging on the holding members 61. Held possible,
A fork 46 that moves along a moving path that includes the carry-in section 2 and the creating section 4, a partition position that passes through at least the upper turning section in the moving path, and a drop position to the creating section near the lower turning section. And a position where the holding member 61 is engaged with the roller chain 34 'against the force of the spring 40, and a position where the holding member 61 is stopped without accompanying the roller chain 34'. And a stop arm 49 that is displaceable between the holding member 61 and the position where the roller chain is associated with the roller chain.

In such a structure, when the fork 46 reaches the upper division position by the movement of the roller chains 34, 34 ',
The blocking arm 49 engages with the holding member 61 to stop the downward movement of the holding member 61, that is, the fork 46 against the clamping force of the holding pieces 36, 37 by the spring 40, while the roller chains 34, 34 'remain unchanged. Continue to move.

Then, when the stop arm 49 is separated from the holding member 61, the holding member 61 again moves together with the roller chains 34, 34 ', and in this way, the printed matter in the upper carry-in section 2 becomes a set number of small bundles. Lower part 4 created by fork 46
And the printed matter stack bundle is created.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention By the way, in such a conventional device, as described above, the rollers 36, 37 constituting the holding member 61 and the roller chain 43 'are pressed by the frictional force of only the spring 40 to cause the roller to rotate. Since it holds the chain 43 'and accompanies it, its holding force is not always sufficient.For example, when the weight of the printed matter becomes larger than expected, its gravity exceeds the holding force. The fork 46 on which the printed material is placed drops together with the holding member 61, which causes an unexpected impact on each part of the apparatus.

And as a method to solve such problems, springs are
It is sufficient to increase the pressing force of 40, but holding piece 3
Since the size of 6,37 is limited, the size of the spring is also limited and a large pressing force cannot be obtained.

Therefore, an object of the present invention is to solve the problems in the above-described conventional stacking bundle creating apparatus, to accurately create stacking bundles with various numbers of copies, and to prevent the holding member from separating from the roller chain and dropping when unexpectedly during that time. It is an object of the present invention to provide an integrated bundle producing apparatus that does not have such a problem, and has a structure that is extremely simple and small, and that does not increase the installation volume of the holding member.

In order to achieve the above-mentioned object, the present invention is an improvement of a part including a holding member of the conventional stacking bundle forming apparatus, and the stacking bundle according to claim 1. In the producing apparatus, magnetic force applying members are provided on the roller chain side of both holding pieces of the holding member, and in the integrated bundle producing apparatus according to claim 2, the roller chain of either one of the holding members. A ball plunge biased by a spring is provided on the surface facing the roller bundle, and in the stack bundle forming apparatus according to claim 3, the roller chain is engaged when the holding member is moved downward, and is stopped when the holding member is stopped. The stacking bundle producing apparatus according to claim 4, further comprising: a ratchet member that is disengaged with the ratchet member to allow only the roller chain to move downward.
In the stack bundle creating device of item 3, the claw member engaging with the roller portion when the roller chain passes through the swivel portion is provided on the holding piece located inside the swivel portion, and the stack bundle creating device according to claim 5. Accordingly, in the integrated bundle producing device according to claim 1, 2, 3 or 4, the pitch of the roller chains on one side of the pair of roller chains is shifted by a half pitch from the pitch of the roller chains on the other side. ing.

Action In the above-mentioned stack bundle producing apparatus, in the apparatus of claim 1, the magnetic force applying members attract each other, and the attraction force increases the frictional force between the holding pieces and the rollers to increase the holding force. In the apparatus according to the second aspect, the ball plunge is biased by the spring to engage the roller of the roller chain, and the holding force is increased by the frictional force. According to the apparatus of claim 3, when the holding member moves downward together with the roller chain, the ratchet member is prevented from engaging with the link of the roller chain to move the holding member downwardly away from the roller chain. However, the ratchet member moves to a position that does not hinder the downward movement of the roller chain when the holding member is stopped by the blocking member. According to the apparatus of claim 4, when the roller chain passes through the swivel portion, the roller chain naturally bends, but since the surface of the holding piece facing this is a flat surface, the contact surface between the two is reduced. However, the claw member of the holding piece prevents the smooth engagement from being hindered by the engagement with the roller. The device according to claim 5 may stop independently of the movement of the roller chain, and when the pitches of the pair of roller chains are the same, vibration is excited in the holding member. However, the pitch is shifted by half to prevent excitation of this vibration.

By stopping at W4 and automatically performing the steps of sorting, stacking, creating a small bundle, dropping a small bundle, and evacuating during this period, a small bundle S1 consisting of a set number of sheets is placed on the mounting plate 11 of the preparing unit 4. It falls one after another. This mounting plate 11 is rotated by 180 ° for each drop of the small bundle S1 by an indexing mechanism 20 for performing indexing rotation by 180 ° through a reduction gear 19 equipped with an electromagnetic clutch and a brake from a motor 18. A stack B1 is formed, and is sequentially moved by the carry-out device C2 toward the next packaging and bundling process.

The above is exactly the same as the above-mentioned conventional stack forming apparatus, and the present invention is an improvement of the holding member 61 and the roller chains 34, 34 'in the above as follows.

As shown in FIG. 7, the roller chain 34 'of the holding pieces 36, 37
Magnet plates 65 and 66 having different polarities are provided on the opposing surfaces sandwiching each other. As shown in FIGS. 8 and 9, a pawl plate 67 is attached to one side of one of the holding pieces 36 along the longitudinal direction, and the upper and lower parts of the holding pieces 36 are provided along the upper and lower surfaces of the holding piece 36 so that the roller chain 34 ′. The claw portion 68 at the tip thereof extends forward from the upper and lower surfaces of the holding piece 36. Further, a sleeve 69 is horizontally provided substantially at the center of both side lines of the holding piece 36, a ball plunge 70 is attached to the distal end opening portion of the sleeve 69, and a spring 71 for pressing the back surface is housed in the sleeve 69. The pressing force of the spring 71 is adjusted by rotating an adjusting screw 72 screwed into the rear end of the sleeve 69.

As shown in FIGS. 7 and 10, a ratchet member 74 is pivotally supported on the holding shaft 41 at one side of one holding piece 37 at an eccentric position. In this case, the center of gravity of the ratchet member 74 is the holding shaft.
In the lower right of FIG. 10 from the vertical line passing through the center of 41, the lower end projection 77 of the ratchet member 74 tends to rotate clockwise so as to constantly contact the edges of the links of the roller chains 43, 43 '. Is given. A stopper pin 75 is provided parallel to the side portion near the holding shaft 41, and lateral movement is restrained by snap rings 76 wound around the holding shaft 41 on both sides of the ratchet member 74. ing.

Further, the roller chains 34, 34 'on one side and the roller chains 34, 34' on the other side have their pitches deviated from each other by a half pitch, and therefore, as a matter of course, the one side sprocket 32, 33 The teeth of the sprockets 32, 33 on the other side are shifted by a half pitch.

In the above-mentioned one, the magnet plates 65 and 66 attract each other, and the attraction force enhances the holding force of the holding chains 36 and 37 to the roller of the roller chain 34 ', and this holding force is exerted by the spring 40 of the holding member 61. Added to holding power.

Next, the ball plunge 70 projects outward from the surface of the magnet plate 65 and is engaged with the roller of the roller chain 34 'by the pressing force of the spring 71 as shown in FIG. Like 66, 66, the holding force of the holding member 61 is increased, and the engaging force is adjusted by the rotation of the adjusting screw 72.

Next, the ratchet member 74 is shown in FIG.
Roller chain 34,3 when the vehicle stops at the stop arm 49.
When 4 ′ moves downward, the ratchet member 74 rotates counterclockwise about the holding shaft 41, so that the protrusion 77 is separated from the link of the roller chains 34, 34 ′, and the roller chains 34, 34 ′ are free. When the holding member 61 moves downward together with the roller chains 34, 34 ', the projection 77 engages with the recess of the link of the roller chains 34, 34', and this engagement causes the holding member 61 to move. Prevents the roller chains 34, 34 'from being separated from the roller chains 34, 34' when they are entrained and falling. When the stopper pin 75 moves upward, the stopper pin 75 is locked to the rear surface of the holding piece 37 to prevent it from turning.

Next, regarding the point that the holding piece 36 is provided with the claw plate 67, when the roller chains 34, 34 'pass through the vertical turning portion,
It naturally bends as shown in FIG. On the other hand, since the portions of the holding pieces 36, 37 facing each other are flat, the frictional force due to the contact surface between the roller chains 34, 34 'and the holding pieces 36, 37 is reduced, and the holding member 61 The holding power of the may decrease and the entrainment may not be performed smoothly. At this time, the claw portion 68 of the claw plate 67 is engaged with the roll of the roller chain 34, 34 ', whereby the holding member 61 of the roller chain 34, 34' is surely accompanied.

Next, regarding the deviation of the pitch between the roller chains 34, 34 ', if the pitches match each other, when the holding member 61 stops and only the roller chain 34' moves,
The holding member 61 vibrates and adversely affects the entire apparatus. However, the half pitch shift prevents the occurrence of the vibration.

In the above-mentioned embodiment, the holding member includes all of the magnetic force applying member, the ball plunge, the ratchet member and the claw member, and the roller chains are shifted by a half pitch, but this is not done. In addition, any one of the members or some members may be provided in combination in the conventional apparatus, and such a thing can be appropriately selected according to need at the time of implementation.

Advantageous Effects of Invention The invention is as described above, and in the conventional stacking apparatus, a magnetic force applying member is provided on both holding pieces of the holding member,
Provide a spring-biased ball plunge on either holding piece,
Alternatively, by providing the holding member with a ratchet member that engages and disengages the roller chain, the holding force of the roller chain by the holding member is increased. The fork does not drop and does not give a harmful impact to each part, and by attaching a claw member to the holding member, the holding member is surely associated with the roller chain even in the vertical turning part, Further, by shifting the mutual pitches of the roller chains by half a pitch, there is an effect that it is possible to prevent the holding member from moving, and further, the structure of each part that brings about such an effect is simple and small. The effect is that no special volume is required for installation.
