Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper receiving device for receiving and collecting papers that are collated and discharged in a collating machine used for collating newspaper inserts. About. 2. Description of the Related Art As a collating machine for gathering several types of leaflets for a newspaper insertion advertisement one by one to form a set, generally, a leaflet on a paper feed table provided in a plurality of upper and lower stages is used as a paper feeder. The sheets are sequentially fed one by one, and are stacked while being conveyed downward by the vertical feeder. The lower part is folded in two, and a set of leaflets is inserted into the leaflet. A vertical collating machine that is integrated by a paper receiving device is used. As shown in FIG. 7, a paper receiving table 3 is provided at the lower side of a paper discharge port 2 of a collating machine 1 as shown in FIG. Three (in general, three) back plates 4a to 4c are fixedly arranged side by side at intervals of 5, and the end portions penetrate through the interval 5 portions and extend to the outside of the back plate 4 (general name of the back plates 4a to 4c). A paper receiving device 9 is used in which the bases of a pair of guides 6, 6 are supported on a frame 7 of the collating machine 1 so as to be swingable around a horizontal axis 8. Guide 6 above
Reference numeral 6 is for guiding the gathering leaflets c discharged at a high speed in the horizontal direction by the unloading conveyor 10 of the gathering machine 1 as shown by the arrow X and collecting them on the paper receiving tray 3. However, in the paper receiving device 9 described above, the discharged leaflet c collides with the guide 6 at high speed at short intervals (for example, every one second), so that the guide 6 jumps up. In order to prevent these from colliding and rebounding, a weight 1
1 is used by attaching it with a screw or the like. However, since the left and right guides 6 and 6 repeatedly bounce (vibrate) separately, the timing of hitting the guide on the left and right sides of the leaflet c is shifted, and the leading edges of the leaflets c in the integrated state are not aligned or shifted left and right. In many cases, the weights 11 are also in an irregular state, and the weight 11 also serves to prevent the backlash c from hitting the back plate 4. However, if the weight 11 is made heavy to suppress the above-mentioned guide 6 from jumping up, If the leaflet c is light, the leaflet c does not reach the back plate 4 due to friction with the lower surface of the tip part of the guide 6 pressed by the weight 11, causing the tip part of the leaflet c to shift forward and backward. I was SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned conventional problems, and it is possible to accumulate collated papers in a state where there is little irregularity due to front-rear or left-right displacement. An object of the present invention is to provide a paper receiving device of a collating machine. In order to achieve the above object, a paper receiving device for a collating machine according to the present invention comprises a front end portion of a paper receiving table disposed at a paper discharge port of the collating machine. A plurality of backboards are arranged side by side and fixed at intervals, and the base ends of a pair of strip-shaped guides whose front ends extend through the gaps to the outside of the backboard,
In a paper receiving device of a collating machine supported on a frame of the collating machine so as to be able to swing around a horizontal axis, a column-shaped weight disposed inside the back plate crosses the spacing section. A support rod rotatably supported around a central axis between the end plates, an upper end of the end plate protruding outside the back plate being connected by a connecting rod, and a lower end of the end plate having an upper surface on the distal end of the guide. And a weight for the paper receiving device, which is provided with a support shaft engaged with the paper receiving device. In the present invention, the term "outside" of the backboard refers to the direction of travel of the paper discharged from the paper discharge port, ie, the front side, and the term "inside" of the backboard refers to the opposite side, ie, the paper. Is referred to as the accumulation unit side. According to this invention, the support shaft presses the distal end of the guide downward by the weight of the connecting rod, the end plate, and the support shaft of the weight for the paper receiving device when the support shaft is mounted on the back plate. In addition, the guide is prevented from jumping up due to the collision of the paper discharged from the paper discharge port, and the left and right support shafts integrally move up and down or vibrate almost in a synchronized state. The paper is guided to the paper tray with little slippage, and this paper collides with the lower part of the weight and is braked and decelerated as it advances toward the back plate while rotating the weight, The rebound of the paper after the collision is suppressed by the braking force due to the inertial rotation of the weight that continues to rotate, so that the paper is kept in a state where there is little front-rear and left-right deviation,
Stacked on a paper tray. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to an example shown in FIGS. First, in FIG. 1, a collating machine 1 includes a sheet feeding table 16, a sheet feeding roller 17 and an auxiliary roller 18 provided near a leading end of the sheet feeding table in a box-shaped casing 15 having front and rear open sides. A sheet feeding device 20 including a piece (separating plate) 19 for preventing double feed;
A vertical feeder having two sets of front and rear, upper and lower sets in parallel, and a leaflet a before collation sent out from each feeder table 16 by a feeder 20 through feed rollers 21 and guide rollers 22. 23, the sheet is fed downward while being sequentially stacked, and in the folding device 24 provided at the lowermost position, the central portion of the folding leaflet b sent from the lowermost sheet feeding device 20 via the feed roller 25 is moved up and down. Folding is performed by the folding blade 26, and a set of leaflets a from above is inserted into the leaflets b by folding rollers 27, and the leaflets (set) c in this collated state are set.
Is discharged from the paper discharge port 2 in the direction of arrow X by the carry-out conveyor 10. Reference numeral 30 denotes a paper receiving device, which has the same configuration as that of FIG. 7 except that a weight 31 for the paper receiving device is used instead of the conventional weight 11 described above. 7 are denoted by the same reference numerals as in FIG. 7, and detailed description thereof is omitted. In this example, as the paper receiving table 3, a tilting paper receiving table is used in which a front portion is supported by a shaft 33 so as to be tiltable and a rear portion is elastically supported by a compression spring 34. Reference numeral 35 denotes a connecting rod for connecting the rear portion of the base 33 and the frame 7 of the collating machine 1 to position the base 33. Reference numeral 3a denotes a cutout portion for when the bundle of the stacks c is pulled out to the side. 3 and 4, illustration of the base 33, the connecting rod 35, and the like is omitted. The weight 31 for the paper receiving device is composed of two end plates 3.
6, 36, the columnar weight 37 is connected to the central axis 3 of the weight.
8 is supported rotatably around the center axis 8 at a position laterally separated from the center axis 38 of the end plates 36, 36.
And the support shafts 39, 39 parallel to the center axis are projected and fixed, and
A connecting rod 40 parallel to the central axis 38
In this example, the weight 37 is made of aluminum, and the others are made of steel. The above-mentioned support shaft 39, connecting rod 40 and end plate 3
6 may be connected by any means such as screwing, caulking, and welding. In this example, a shaft 41 (see FIG. 4) screwed into the weight 37 is rotatably supported by the end plate 36. Instead of this, for example, the weight 37 is penetrated. Weight 37 around the axis
May be rotated. The distance between the end plates 36, 36 is smaller (for example, 2 to 5 mm) than the width of the central back plate 4b, and the weight 31 for the paper receiving device is placed above the back plate 4b on both side edges of the back plate 4b. The weight 37 is lowered at the position inside the back plate 4b by lowering while fitting the end plates 36, 36 to the portion.
Is placed on the paper tray 3 in the horizontal direction, and the back plate 4 (4a to 4a)
4c), the lower support shafts 39, 39 of the end plates 36, 36 projecting to the outside of the back plate 4 across the space 5 are engaged with the upper surfaces of the distal end portions of the guides 6, 6, and the connecting rod 40 is moved upward. Position. As a result, the weight 31 for the paper receiving device is set in a vertically movable manner on the back plate 4b. In the above set state, as shown in FIG. 5, the respective weights W _{1 to} W ₃ of the connecting rod 40, the end plate 36, and the support shaft 39 act as a rotational force around the central axis 38. As a result, the support shaft 39 presses the distal end of the guide 6 downward with the pressing force P. Therefore, when the union c is discharged by the collating machine 1 in the direction of the arrow X (see FIG. 2) and collides with the guide 6, the uplift of the guide 6 is small due to the pressure P of the support shaft 39. Is suppressed. Further, since the two left and right support shafts 39, 39 are integrated by the end plate 36 and the connecting rod 40, the two guides 6, 6 subjected to the continuous collision of the flier c move up and down or vibrate substantially in synchronization. The flyer c flies over the paper receiving tray 3 while being guided by the guides 6 and 6 in a state in which there is little deviation in front and rear or left and right. The lead c guided by the guide 6 as described above advances as shown by an arrow V in FIG. 5 and collides with the lower portion of the weight 37, passes under the weight 37, and passes through the lower plate 4 (4a to 4a).
c), the weight 37 rotates in the direction of the arrow R while braking the flicker c by the pressing force Q due to its own weight, and decelerates the flicker c. The rebound is caused by the friction braking force by the weight 37 that tries to continue rotating in the direction of the arrow R (the direction opposite to the rebound) while applying the pressing force Q, that is, the weight 37.
The flyer c is stopped on the paper receiving table 3 with little rebound while the weight 37 also stops the inertial rotation, and the accumulation of one set of flyers c is completed. Hereinafter, the leaflets c which are successively discharged from the paper discharge port 2 are accumulated in the same manner as described above. FIG. 6 shows a state in which the stacking of the leaflets c has progressed, and the paper receiving tray 3 has become nearly horizontal due to the weight of the leaflets,
Although the guide 6 is also raised, even in this state, the leading end of the flier c is aligned and the right and left misalignment is small due to the guide uplift and the fluttering bounce suppressing action by the paper receiving device weight 31 as described above. The state is obtained. Further, by selecting the size and material weight of each member of the paper receiving device weight 31, the pressing force P, the pressing force Q and the braking force due to the inertial rotation, that is, the guide pop-up suppressing force and the flickering-suppressing force are reduced. , Can be set independently, and the optimum suppressing force according to the weight, the frictional force, etc. of the leaflet c can be obtained. FIG. 4 shows the accumulated c as indicated by an arrow S.
When the hand is pulled out to the side as shown by the arrow, the end plate 36 is engaged with the side edge of the back plate 4b, and the weight 31 for the paper receiving device moves in the arrow S direction together with the leaflet c. And the connecting rod 40 prevents the end plate 36 from falling inside the back plate, and the weight 31 for the paper receiving device drops along the back plate 4b even when the leaflet c is taken out, so that the normal position is maintained. Since the same operation as above is continued, the extraction of the leaflet c is
This can be performed at any time during the continuous discharge and accumulation of the flyer c without any trouble. The present invention is not limited to the above example. For example, the shape of the end plate 36 may be other than the above, and the end plate 3 may be replaced with the two support shafts 39.
6, 36 may be used, and the specific structure and material of each part of the weight 31 for the paper receiving device may be
Other than the above may be used. Further, the collating machine 1 may have a configuration other than the above, such as a configuration in which the sheet feeding devices 20 are arranged in a row. In the above example, the case where three back plates 4a to 4c are arranged side by side on the paper receiving tray 3 has been described.
The present invention can be applied to the case where the number of sheets is two or more, or the like. In any case, the space where the tip of the guide penetrates up and down [Note: In the latter case, for example, when the back plate 4c is missing, As in the case of the plate 4b, the "spacing portion" on the side where there is no adjacent back plate refers to the side of the side edge of the back plate (4b). ], The end plate and the support shaft may be located. Further, in the above-described example, the case where the tilting paper receiving tray 3 is used has been described. However, the present invention is also applicable to a paper receiving device having a fixed paper receiving tray. The present invention can be applied to a paper receiving device of a collating machine for other purposes such as printing and bookbinding, in addition to the above-mentioned collating machine for flyer collating. As described above, according to the present invention,
The pressure applied from the support shaft of the paper receiving device restrains the guide from rising, and the braking force due to the inertial rotation of the weight prevents the paper from colliding against the backboard from rebounding. The collated paper can be accumulated on the paper receiving tray in a state where the irregularity due to the collation is small.
