FIG. 6 is a flowchart showing a procedure until a newspaper bundle printed on a rotary press and stacked on a counter stacker is shipped.
The newspaper printed in the printing press S1 of the rotary press is fed into the counter stacker CS through a newspaper carrier. In this counter stacker CS, the number of newspapers is counted in the counting division step S2, and a bundle of newspapers called a batch is created in the next small bundle creating step S3 based on the counting result. The batch created in the small bundle creating step S3 is transferred to the rotating basket in the large bundle creating step S4, where the batches are alternately inverted and overlapped to create a large bundle of newspaper bundles.

  The newspaper bundle is sent out from the counter stacker CS through the sending step S5 and delivered to the underlaying step S6. In this underlaying step S6, in order to prevent the newspaper in the lowermost layer of the newsprint bundle sent out from the counter stacker CS from being soiled during conveyance, a patron-like underlaying paper is placed under the newsprint bundle, and the address is the next step. Delivered to the paper loading step S7. In this address paper loading step S7, an address paper preprinted with the destination and number of copies of the newspaper bundle, the name of the newspaper company, a barcode, etc. is loaded on the newspaper bundle. The newspaper bundle on which the address paper is mounted is packaged and bound in the packaging / binding step S8, and a track on which a predetermined delivery truck stands by based on the shipping destination information read from the address paper in the address paper reading step S9. It is conveyed to the shipping process S10 which is a gate.

FIG. 7A is a side view showing an example of the address paper mounting apparatus provided in the address paper mounting process S7, and FIG. 7B is an enlarged view of the conveyor portion in the address paper mounting apparatus of FIG. 7A. It is a front view.
The address paper loading device 100 is provided on the base 101 arranged along the transport path of the conveyor Sa for transporting the newspaper bundle S, and the delivery destination and number of newspaper bundles S, the name of the newspaper company, and the like. The address sheet supply unit 140 that supplies the address sheet D on which a barcode or the like is printed in advance, and the address sheet D that is provided so as to protrude from the address sheet supply unit 140 to the conveyor Sa side and that is supplied from the address sheet supply unit 140. Is positioned above the newspaper bundle S, and the address paper standby section 120 that holds and waits, and the address paper mounting section 150 that receives the address paper D in the standby state from the address paper standby section 120 and delivers it to the newspaper bundle S. Have.

The address paper supply unit 140 stocks the first address paper table 141 for stocking the address paper D in which the number of copies and the destination are displayed, and the first address paper D for stocking a standard newsprint bundle in which the number of copies and the destination are not displayed. The address sheet D of the first address sheet table 141 is sent to the address sheet standby unit 120 by the conveyor 143, and the address sheet D of the second address sheet table 142 is , And sent to the address paper waiting unit 120 by the conveyor 144.
A reader 145 that reads the number of copies written on the address sheet D is provided in the middle of the conveyor 143.
The address sheet standby unit 120 includes a pair of conveyors 130 and 131 that convey the address sheet D while holding the vicinity of both ends from both the upper and lower sides.
FIG. 7B is a front view of the conveyors 130 and 131. As shown in FIG. 7B, each of the conveyor 130 and the conveyor 131 includes a pair of pulleys 130a and 131a opposed to each other at a width interval narrower than the width of the address sheet D, and the pulleys 130a and 131a. And round belts 130b and 131b wound around the belt.
In the example shown in FIG. 7B, a single round bell 131b is wound around the pulley 131a of the conveyor 131 disposed above, and parallel to the pulley 130a of the conveyor 130 disposed below. Two round belts 130b are wound around the belt.

The address paper mounting unit 150 includes a cylinder 151 having a piston rod 151a that can be moved up and down in the vertical direction, a mounting plate 155 that is attached to the tip of the piston rod 151a and that moves up and down with the lifting and lowering of the piston rod 151a, and the mounting plate 155. And a suction pad 155a for sucking the address paper D and a hollow rod 153 attached to the mounting plate 155 in parallel with the piston rod 151a. The cylinder 151 is connected to and supported by the connecting member 152 on the main body of the address sheet mounting apparatus 100.
The other end (upper end) of the hollow rod 153 is connected to the air supply unit 160 via an air tube 154a and a retractable coiled air tube 154b. Then, when the air supply unit 160 is driven, suction air or jet air is supplied to the suction pad 155a via the rod 153 and the air tubes 154a and 154b.
The air supply unit 160 includes a blower B that can supply both suction air and jet air, and an electromagnetic valve 161 that switches the air supplied to the suction pad 155a between the suction air and the jet air. . The driving and stopping of the blower B and the operation of the electromagnetic valve 161 are performed by a control device (not shown) of the address paper mounting device 100.

FIG. 8 is a diagram showing how the address sheet D is mounted using the address sheet mounting apparatus 100 configured as described above.
As shown in FIG. 8A, the address sheet D is attracted to the suction pad 155a by suction air, and the mounting plate 155 and the suction pad 155a are lowered along with the extension operation of the piston rod 151a by driving the cylinder 151. Thus, the belts 130 b and 131 b of the conveyors 130 and 131 are separated from each other and lowered toward the newspaper bundle S.

  As shown in FIG. 8 (b), when the address sheet D reaches a predetermined position near the upper surface of the newspaper bundle S (about 20 to 30 mm from the upper surface of the newspaper bundle S), FIG. As shown, air is ejected from the suction pad 155a by switching the electromagnetic valve 161, and the address sheet D is delivered to the upper surface of the newspaper bundle S. At the same time, the piston rod 151a is retracted and the mounting plate 155 and the suction pad 155a are raised and returned to their original positions.

As described above, the mounting plate 155 and the suction pad 155a at the tip of the piston rod 151a are not in contact with the upper surface of the newspaper bundle S because the mounting plate 155 and the suction pad 155a are driven by the driving force of the cylinder 151. When pressed against the sheet, the packaging of the newspaper bundle S is damaged, and not only the stain is attached to the newspaper bundle S, but also a large load is applied to the cylinder 151, causing the cylinder 151 to fail or shorten its life. Because.
Therefore, for example, in the illustrated address paper mounting apparatus 100, a position detection unit 170 that detects the height positions of the mounting plate 155 and the suction pad 155a is provided in the vicinity of the mounting unit 150, and the driving of the cylinder 151 is controlled. Yes.

The position detection unit 170 is erected on the mounting plate 155 in parallel with the cylinder 151, and is formed to penetrate with a rod-shaped detection member 171 that moves up and down together with the mounting plate 155 at a predetermined interval in the vertical direction of the detection member 171. It has a plurality of detection holes 171a, a projection unit that is positioned and attached to a fixed part of the address paper mounting apparatus 100, emits a beam light toward the detection hole 171a, and a sensor 172 having a light reception for receiving the beam light. is doing.
The position of the mounting plate 155 and the suction pad 155a is counted by counting the number of times the beam light received through the detection hole 171a and received by the light receiving portion when the detection member 171 moves up and down along with the lifting operation of the mounting plate 155. Can be judged. Then, the thickness information of the newspaper bundle S on which the address paper D is mounted is transmitted in advance from the previous process such as the counter stacker CS, and the loading plate 155 and the suction pad 155a are moved to a height position corresponding to the thickness of the newspaper bundle S. I try to make it reach.

However, in the address paper mounting apparatus 100 described above, the air is supplied to the suction pad 155a, and the mounting plate 155 and the suction pad 155a are set in addition to the air supply unit 160 that switches between suction air and ejection air. Software to control the driving of the cylinder 151 and software to control the switching between air suction and ejection are required to reach the height position of the machine, making the device configuration complicated and large, and the device price is also high There is a problem of raising it.
Further, in order to prevent the address sheet D from being firmly pressed against the newspaper bundle S together with the mounting plate 155 and the suction pad 155a, the mounting plate 155 and the suction pad to a predetermined height according to the thickness of the newspaper bundle S. Further, a means such as the position detection unit 170 for reaching 155a is required, the thickness of the newspaper bundle S is judged from the number of copies and the number of pages, and the mounting plate 155 and the suction pad 155a are close to the upper surface of the newspaper bundle S There is a problem in that a means for reaching is required, which further complicates the apparatus configuration and increases the apparatus price.
Further, in the address paper mounting apparatus 100 shown in FIG. 7, the address paper D is sandwiched by the round belts 130b and 131b of the conveyors 130 and 131 when the address paper D is delivered to the mounting plate 155 and the suction pad 155a. However, when the address sheet D is deflected during the conveyance and the holding balance between the both ends of the address sheet by the round belts 130b and 131b becomes extremely uneven, the mounting plate 155 and the suction pad 155a are brought into contact with the conveyors 130 and 131 in a so-called one-hanging state. The address sheet D is received from the mail, and there is a problem that the address sheet D is damaged or wrinkles and dirt are generated.

  Further, when packaging and bundling newsprint bundles in the subsequent process, or when reading the address paper D before the track gate, it is necessary that the address paper D is accurately mounted at a predetermined position of the newsprint bundle S. However, the curl of the upper surface of the newspaper bundle S, the air flow and the air resistance when the address paper D is delivered from the mounting plate 155 and the suction pad 155a to the upper surface of the newspaper bundle S, the installed address paper D and the newspaper bundle S Accurate positioning is difficult due to an air layer formed between the upper surface and the like. For this reason, there is a problem that the operator must constantly monitor the loading status of the address sheet D and adjust the mounting position of the address sheet D as necessary. Such work not only increases the work burden on the operator, but also makes it difficult to unmanned printing work and is one of the factors that hinder cost reduction.

In addition, after placing the address paper on the newsprint bundle, we proposed a technology that charges the address paper with static electricity and prevents the address paper from falling off the newsprint bundle or being greatly displaced from a predetermined position due to electrostatic attraction. (See Patent Document 2).
According to this technology, the address paper can be stably held on the newsprint bundle by electrostatic attraction, and there is an advantage that it is not necessary to constantly monitor the fall and displacement of the address paper, and the usability is improved. Even in the techniques described in the literature, there is a problem that a mechanism for generating static electricity is required, the apparatus becomes complicated and large, and the apparatus cost increases.
JP-A-7-267217 (see abstract)

  The present invention has been proposed in order to solve such problems, and has a simple and inexpensive apparatus configuration, and can be placed at a predetermined position on the surface of the printed paper bundle regardless of the thickness of the printed paper bundle such as a newspaper bundle. The address sheet can be securely positioned and mounted. Furthermore, when the address sheet is mounted on a printed paper bundle, the address sheet is not damaged, wrinkled or soiled. The purpose of the present invention is to provide an address paper loading device that can save labor in the process from shipping to shipping.

  In order to achieve the above-mentioned object, the invention according to claim 1 is directed to a predetermined set of printing paper bundles such as a destination and the number of copies of the printing paper bundle on an upper surface of the printing paper bundle formed by stacking a plurality of printing papers. In the address paper mounting apparatus for mounting the address paper in which the information is described, a transport means for transporting the address paper to a standby position above the print paper bundle, the address paper is received from the standby position, and the contact paper is in a contact state. An address paper holding member that holds the address paper and lowers it to the upper surface of the printed paper bundle, engages with the address paper holding member, moves the address paper holding member up and down, and the address paper holds the address paper A driving body that lowers the address paper holding member toward the upper surface of the printing paper bundle so as not to be separated from the member; and the driving body and the address when the addressing paper holding member comes into contact with the printing paper bundle. With paper holding member It is constituted and a disengagement means for releasing the engagement.

According to this configuration, the address sheet is held only by contacting the address sheet holding member.
There is no need to adsorb address paper to the suction pad by suction air, and no need to deliver address paper to the printed paper bundle by jetting air, eliminating the need for an air supply unit that switches between air supply and switching, and the configuration of the address paper mounting device It can be made simple and compact, and the apparatus price can be reduced.
In order to hold the address paper in contact with the address paper holding member, for example, the lowering speed of the address paper holding member may be set larger than the free fall speed of the address paper.

Further, when the address sheet holding member comes into contact with the print paper bundle, the engagement member releases the engagement between the driving body and the address sheet holding member, so that the address sheet is driven by the driving force of the driving body. Is not strongly pressed against the printing paper bundle, that is, only the weight of the addressing paper holding member acts on the printing paper bundle, so that the packing state of the printing paper is not damaged or dirt is not adhered.
Further, when the address paper holding member comes into contact with the printed paper bundle, the engagement between the driving body and the address paper holding member is released, so the load acting on the driving body is reduced, It is possible to prevent a decrease in life.
Furthermore, since the address paper holding member is formed of an elastic member, even if the address paper holding member is pressed against the upper surface of the printing paper bundle, the printing paper bundle is not damaged by the address paper holding member.

The portion of the address sheet holding member that contacts the address sheet may be formed of an elastic member that elastically deforms when contacting the print sheet bundle.
By doing so, even if the surface of the printed paper bundle is curved or wavy, the addressable paper holding member can be elastically deformed according to the surface shape of the printed paper bundle, and the addressed paper is in a state where there is no gap In addition, the pressure applied to the address paper can be made uniform and reliably mounted on the surface of the printed paper bundle. Further, when using thermal paper as the address paper, even if the edge portion of the address paper holding member is pressed against the address paper, the pressing force applied to the address paper is reduced by elastically deforming the edge portion. Because there is no danger of smearing the address sheet.
The elastic member may be formed of a porous material such as sponge as described in claim 3.
By forming a part or all of the address paper holding member with such a porous material, the contact area between the address paper and the address paper holding member is reduced, so that the address paper holding member can be removed from the upper surface of the printed paper bundle. When detaching, the releasability between the address paper holding member and the printed paper bundle is improved, and the amount of air flowing between the address paper and the address paper holding member is reduced, so that the address paper is misaligned. It can be effectively prevented.

According to a fourth aspect of the present invention, at least a portion of the address sheet holding member that comes into contact with the address sheet has a circular shape smaller than the address sheet.
Thus, by making the part of the address sheet holding member that contacts the address sheet smaller than the address sheet, it is possible to effectively form an air layer due to air inflow when the address sheet is mounted on a bundle of printed sheets. There is an advantage that the address sheet can be prevented from being lifted by air inflow. In addition, by making the circle smaller than the address paper, even if the surface of the printed paper bundle is curved or wavy, the printing paper is effectively displaced when the address paper is pressed against the printed paper bundle. There is an advantage that it can be prevented.

According to a fifth aspect of the present invention, the transporting unit includes a transporting conveyor that places the address sheet and transports the address sheet to the standby position, and a sandwiching position that sandwiches the address sheet with the transporting conveyor; A pressing member provided so as to be pivotable between a separation position where the address sheet is released from the conveyance conveyor and the holding state of the address sheet is released; and when the address sheet is delivered to the address sheet holding member, the pressing member Driving means for rotating the member from the clamping position to the separation position is further provided.
As described in claim 6, the pressing member may include a roller or a belt that conveys the address sheet to the standby position in cooperation with the conveying conveyor.
According to this configuration, the address sheet is held at a predetermined position while being sandwiched between the transport conveyor and the pressing member until the address sheet is delivered to the address sheet holding member. When the address sheet is transferred to the address sheet holding member, the pressing member rotates with respect to the transport conveyor to release the holding state of the address sheet. Therefore, when the address sheet is transferred to the address sheet holding member, the address There will be no paper delivery mistakes, breakage, wrinkles or dirt.

According to a seventh aspect of the present invention, the disengaging means is provided on the elevating member that protrudes from the driving body and moves up and down by driving the driving body, and the address sheet holding member. And an engaging portion that contacts and engages from above.
According to this configuration, the address sheet holding member normally has the engaging portion in contact with the elevating member of the driving body and moves up and down together with the elevating member. When the address sheet holding member comes into contact with the print sheet bundle, the engagement between the elevating member and the engaging portion is released. Therefore, when the address paper is transferred to the printed paper bundle, the urging force acting on the printed paper bundle is only a light weight including the weight of the address paper holding member. Therefore, the packing form of the printing paper is not damaged or dirt is attached.

Further, according to the above configuration, the address sheet holding member follows the lowering of the elevating member and descends due to free fall. Therefore, even if the thickness of the print sheet bundle delivering the address sheet is different, There is no need to predict or calculate the height position of the upper surface in advance, and it is not necessary to detect and control the height position of the address sheet holding member. Therefore, the apparatus configuration can be made extremely simple and inexpensive.
In the case of the invention described in claim 7, when the elevating member starts to descend, the address sheet holding member can be started to descend following the descending of the elevating member. It is preferable to provide an urging means as described so that when the elevating member starts to descend, the address paper holding member is pushed downward to prompt the start of lowering of the address paper holding member.

According to the present invention, there is no need for an air supply unit for sucking the address paper or delivering the address paper to the printing paper, and the delivery of the address paper to the upper surface of the printing paper bundle is reliably delivered. It is possible.
In addition, there is no inconvenience of damaging the packing form or attaching dirt due to the urging force when delivering the address sheet.
Furthermore, even if the thickness of the printed paper bundle is different, it does not require a means for detecting the height position of the address paper holding member or determining / detecting the thickness of the printed paper bundle. The address paper can be mounted on the upper surface of the printing paper reliably and without causing damage, wrinkles, dirt, and the like.
Therefore, the addressing paper mounting device that is simple and small in apparatus configuration, can reliably load addressing paper at a predetermined position on the upper surface of the newspaper bundle, and can save labor in the process from addressing address loading to shipping. Can be obtained.

DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a side view illustrating a configuration of a main part of an address paper mounting apparatus according to an embodiment of the present invention.

Since the configuration of the address sheet supply unit 4 is the same as that of the conventional address sheet supply unit 140 described with reference to FIG. 7, illustration and detailed description thereof will be omitted.

  The address paper mounting section 5 is attached to a rodless cylinder 51 erected in the vertical vertical direction and a piston 51b (see FIG. 2) that can be moved up and down of the rodless cylinder 51. Elevating member 51a protruding to the left), a guide 54 erected in parallel with the rodless cylinder 51, and holding the address paper that is vertically moved up and down by driving the rodless cylinder 51 while being guided by the guide 54 Member 55.

The address sheet holding member 55 includes a mounting plate 55a attached to the lower end of a rod 53 extending in the vertical vertical direction in parallel with the guide 54, and an elastic member 55b attached to the lower surface of the mounting plate 55a.
In this embodiment, the elastic member 55b is formed in a circular shape smaller than the address paper D, and is formed of a material that is elastically deformed when the address paper D is pressed against a newspaper paper bundle that is a printed paper bundle. As a material for forming the elastic member 55b, a porous material in which air can freely enter and exit, such as a sponge, may be used.

  A plate-like slider 56 that moves up and down while being guided by the guide 54 is attached to the upper end of the rod 53. As shown in FIG. 2A, a guide hole 56a through which the guide 54 is inserted is formed on one side of the slider 56, and two legs extending to both side surfaces of the rodless cylinder 51 are formed on the other side. A portion 56b is formed. The two leg portions 56b restrict the slider 56 from rotating about the guide 54 as an axis.

The upper end of the guide 54 and the upper end of the rodless cylinder 51 are connected by a connecting member 52, and a compression coil spring 6 that urges the slider 56 downward is guided to the guide 54 between the connecting member 52 and the slider 56. (Hereinafter referred to as spring 6) is inserted.
This spring 6 is for assisting the initial movement when the slider 56 starts to descend. That is, in this embodiment, when the rodless cylinder 51 is driven and the elevating member 51a starts to descend, the slider 56, the rod 53, and the address sheet holding member 55 are lowered by their own weight. The friction between the guide 56 and the guide 56 may delay the start of the lowering of the slider 56 or prevent the lowering of the slider 56. Therefore, in this embodiment, when the rodless cylinder 51 is driven and the elevating member 51a starts to descend, a spring 6 is provided as an urging means that pushes the slider 56 downward and prompts the slider 56 to begin to descend. Yes.

  If the slider 56 can be pushed downward to start the lowering when the elevating member 51a starts to descend, the biasing means is not limited to the compression coil spring 6, but is a tension coil spring or a leaf spring. Alternatively, a cylinder such as an air cylinder may be used.

As a pressing member that holds the address sheet D transported up to the waiting position together with the first conveyor 30 and moves it to the waiting position, and holds it so as not to be displaced at the waiting position. And a second conveyor 31.
The first conveyor 30 is a well-known one composed of a pulley disposed oppositely and a belt wound around the pulley. As shown in FIG. 2B, the pair of left and right pulleys and belts constituting the first conveyor 30 are preferably larger than the width of the address sheet D so that the address sheet holding member 55 can be inserted. It is arranged at a slightly narrow width interval.

Since the first conveyor 30 is the same as the conventional conveyor 130 described with reference to FIG. 7, further detailed description is omitted.
In this embodiment, the second conveyor 31 is composed of a plurality of rollers arranged at the same width intervals as the pulleys of the first conveyor 30. This roller is attached to a side surface of a rod-like support member 32 provided in parallel with the conveying direction of the address sheet D by the first conveyor 30. As the second conveyor 31, the address paper D can be conveyed to the standby position in cooperation with the first conveyor 30, and the address paper D can be transferred to and from the first conveyor 30 at the standby position. As long as it can be sandwiched and held, it is not limited to the one constituted by a plurality of rollers as described above, and is constituted by a pulley and a belt, like the first conveyor 30. Also good.
A support member 32 to which the second conveyor 31 is attached is rotatable in a clockwise direction and a counterclockwise direction in FIG. 1 about an axis 36 parallel to a rotation axis of a pulley constituting the first conveyor 30. . Therefore, the second conveyor 31 is centered on the shaft 36 and has a sandwiching position for sandwiching the address sheet D together with the first conveyor 30, and a separation position for separating the address sheet D from the first conveyor 30. Can be rotated between the two.

An arm 32a extending upward is formed at one end on the shaft 36 side of the support member 32, and a cylinder 33 is provided at a position opposite to the upper end of the arm 32a. And the front-end | tip of the piston rod 33a which can move forward / backward of the cylinder 33 is connected with the upper end of the arm 32a. When the cylinder 33 is driven and the piston rod 33a is extended, the arm 32a is pushed to the address paper supply unit 4 side to rotate the support member 32 and the second conveyor 31 in the clockwise direction. The second conveyor 31 is separated. Further, when the piston rod 33a is retracted, the support member 32 and the second conveyor 31 are rotated counterclockwise to return the second conveyor 31 to the clamping position.
The driving of the rodless cylinder 51 and the cylinder 33 is controlled by a control device (not shown).

Next, the operation of the address sheet mounting apparatus having the above configuration will be described with reference to FIGS.
FIG. 3 is a diagram illustrating a process from when the address sheet D is supplied from the address sheet supply unit 4 to the standby position until the address sheet holding member 55 receives the address sheet D from the standby position and lowers it. FIG. 4 is a diagram illustrating a process from the loading of the address paper D to the newspaper bundle S to the ascent of the address paper holding member 55 in the process subsequent to FIG. 3.

  The address sheet D supplied from the address sheet supply unit 4 is introduced into the address sheet standby unit 2 while being conveyed by the first conveyor 30. In the vicinity of the standby position of the address paper standby unit 2, as shown in FIG. 3A, the address paper D is sandwiched between the upper and lower conveyors 30 and 31 and conveyed to the standby position. At the standby position, the address sheet D is positioned and held while being sandwiched between the first conveyor 30 and the second conveyor 31.

  When the newspaper bundle S is conveyed directly below the standby position of the address sheet D, the rodless cylinder 51 is driven to lower the elevating member 51a. Since the slider 56 to which the rod 53 and the address sheet holding member 55 are attached is pressed against the elevating member 51a from above by the spring 6, when the elevating member 51a starts to descend, as shown in FIG. Following this downward movement, the address sheet holding member 55 starts to descend toward the address sheet D.

  At this time, the cylinder 33 is driven to extend the piston rod 33a, push the arm 32a, and rotate the second conveyor 31 together with the support member 32 in the clockwise direction. Thereby, as shown in FIG. 3B, the second conveyor 31 is separated from the first conveyor 30, and the holding of the address sheet D by the first conveyor 30 and the second conveyor 31 is released. The address sheet D becomes free.

The address sheet holding member 55 receives the address sheet D in the free state at the standby position, and lowers it toward the newspaper bundle S as shown in FIG. Thus, the nipping of the address sheet D by the first conveyor 30 and the second conveyor 31 is released, and the address sheet D is transferred to the address sheet holding member 55, so that the address sheet D is deflected during the conveyance. Even if the holding balance of the address sheet D by the first conveyor 30 and the second conveyor 31 becomes extremely uneven, the inconvenience that the address sheet holding member 55 receives the address sheet D in a so-called one-hanging state is Does not occur.
In the present invention, no air suction means for adsorbing and holding the address paper D on the address paper holding member 55 is provided. Therefore, in order to prevent the address paper D from being detached from the address paper holding member 55, the address paper holding member 55 is lowered at a speed higher than the speed at which the address paper D is dropped.

  When the address sheet D comes into contact with the upper surface of the newspaper bundle S, the lowering of the address sheet holding member 55 and the address sheet D is restricted even when the rodless cylinder 51 is driven. As described above, the elevating member 51 a is separated from the slider 56. Therefore, the address paper D and the address paper holding member 55 are pressed against the upper surface of the newspaper bundle S with a small force including the weight of the address paper holding member 55.

FIG. 5 shows a state when the address sheet D comes into contact with the upper surface of the newspaper bundle S.
Since the address sheet holding member 55 has an elastic member 55b formed of a porous elastic material such as a sponge, when the address sheet D comes into contact with the upper surface of the newspaper bundle S, the shape of the upper surface of the newspaper bundle S The elastic member 56b is elastically deformed in accordance with the above, and the address sheet D can be mounted on the upper surface of the newspaper S without a gap. Therefore, even if the surface of the newsprint bundle S is curved or wavy, the elastic member 55b is elastically deformed according to the surface shape of the newsprint bundle S, so that the address paper D can be surely provided with no gap. It can be mounted on the surface of the bundle S.
Further, only a small force including the weight of the address sheet holding member 55, that is, a small force that is the sum of the weights of the address sheet holding member 55, the rod 53, and the slider 56, acts on the upper surface of the newspaper S. It does not impair the package of S or attach dirt.

Further, since the elastic member 55b is formed of a porous material (sponge), the contact area with the address paper D can be reduced, and the address paper is retained after the address paper D is mounted on the upper surface of the newspaper bundle S. Even when the member 55 is raised, the inconvenience that the address sheet D is attracted to the elastic member 55b and lifted from the upper surface of the newspaper bundle S is unlikely to occur. In addition, since a porous material such as a sponge easily circulates air, an air layer is not formed between the address paper D and the elastic member 55b, and this also causes the address paper D to stick to the elastic member 55b and newspaper. The inconvenience of being lifted from the upper surface of the bundle S is unlikely to occur.
Further, since the address paper D does not stick to the elastic member 55b and does not float up, an air layer is not formed between the newspaper bundle S and the address paper D, and misalignment hardly occurs.
After the address paper D is mounted at a predetermined position on the upper surface of the newspaper bundle S, the rodless cylinder 51 is driven to raise the elevating member 51a. Then, as shown in FIG. 4B, the elevating member 51a comes into contact with the slider 56 again to lift the slider 56 and return to the initial state shown in FIG.

Although a preferred embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment.
For example, in the above description, the rodless cylinder 51 has been described as an example of a driving body for moving the address sheet holding member 55 up and down, but a normal cylinder having a telescopic piston rod can also be used. Further, not only a cylinder but also a combination of a ball screw / nut mechanism and a motor, a combination of a belt / pulley mechanism and a motor, a linear motor, or the like can be used.
In the above description, the slider 56 has two leg portions 56b extending to both side surfaces of the rodless cylinder 51, and the rotation of the slider 56 is regulated by the leg portions 56b. It is also possible to effectively restrict the rotation of the slider 56 by providing a plurality of these.

  Furthermore, in the above description, as an example of the pressing member, the second conveyor 31 that conveys the address sheet D to the standby position in cooperation with the first conveyor 30 is described as an example. The address sheet D may not be in the form of a conveyor that conveys the address sheet D. The address sheet D conveyed to the standby position by the first conveyor (conveyor conveyor) 30 is held and held together with the first conveyor 30 at the standby position. Anything to do. For example, the pressing member is composed of a plurality of rollers, and when the address paper D is conveyed to the standby position, the roller 33 is moved to the first conveyor 30 side by driving the cylinder 33 so that the address paper D is When the address sheet D is transferred to the address sheet holding member 55, the rollers are moved away from the first conveyor 30 to release the nipping. May be.

  The present invention is applicable not only to newspapers but also to all types of printing paper as long as printing paper is stacked and addressed paper is mounted.
