Description

  The present invention relates to a collator that automatically collates a plurality of types of paper, and more particularly, to a collator that can prevent dust from diffusing due to collation.

  2. Description of the Related Art In recent years, collators (collating machines) that automatically stack a plurality of types of sheets one by one into a single bundle have become widespread. In particular, in a newspaper insert advertising collator, in addition to the ability to reliably collate a large number of 20 or more types of leaflets of different thickness and paper quality one by one, the bundle of leaflets is discharged at a rate of 2 or more copies per second. Now, it has high-speed performance that can process more than 10,000 copies a day.

  Such a newspaper advertisement collator is similar to the collator 1I described in Japanese Patent Laid-Open No. 2002-3075 and shown in the longitudinal sectional view of FIG. In this state, a plurality of stages are stacked in the vertical direction. This collator 1I sends leaflets from the sheet feed tray 20 of the sheet feeder 2C one by one by the sheet feed roller 22 to the downstream side, and a set of leaflets sent in order from the sheet feeders 2C, 2C,. Are bundled by a leaflet sent from the lowermost sheet feeding device 2D to form a bundle, which is sent to the paper discharge tray 41 by a conveyor or the like and stacked.

  However, in the recently increasing color printing flyers, starch and other powders are sprayed on the surface to prevent the surface ink printed on the paper from sticking to the next paper. Makes it easier to scatter around. In addition, because of the high-speed collation as described above, the lint of the leaflet itself is easily separated and released into the air, and the generation of dust associated with the collation work is a cause of the deterioration of the work environment. As a big problem.

  Dust from such leaflets falls along the leaflet flow to the collator's internal space and accumulates in the middle of the shelf and the lower part of the machine, but part of it is rolled up in the air by the leaflet's movement and released outside the collator. And may cause health damage because it reaches the front of the worker. In addition, the leaflet bundle after collation is discharged at a relatively high speed from the lower part of the machine, but the dust accumulated at the lower part of the machine is attracted to the movement and discharged to the outside. Will lead to accumulation.

Therefore, it is conceivable to use a ventilator as a countermeasure against dust trouble by the collator. However, a ventilator with general performance cannot generate an air current over the entire room, so a sufficient dust removal effect cannot be expected. In addition, when a plurality of powerful ventilation fans are used, the indoor air conditioning effect is greatly impaired. On the other hand, it is conceivable to install a stationary air cleaner or dust collector. However, a large-scale device is required to purify the entire room, which causes an increase in installation cost and maintenance cost. Further, no matter how high-performance equipment is installed, if dust is collected after the dust is discharged from the collator, it cannot be prevented that an operator existing in the meantime sucks the dust.
JP 2002-3075 A

  An object of the present invention is to solve the above-described problems, and an object of the present invention is to enable the collator to effectively prevent dust from being diffused by collating work without using a large-scale device.

  Therefore, the present invention has a plurality of types of paper feeding means provided in the main body casing in the vertical direction, and a paper bundle discharge port for discharging the paper bundle after collation is provided below the lowermost paper feeding means. In the collator that automatically performs the collating operation of, in order to open the suction port of the intake passage extended from the dust collecting means for sucking the air containing dust and capturing the dust with the filter in the internal space of the main body casing It has a structure, and by opening the suction port at a predetermined position in the internal space and driving the dust collecting means, dust collected in the internal space by collating work is collected before being released to the outside. did.

  In this way, the suction port of the intake passage that extends from the dust collecting means is opened inside the collator to enable suction, so even relatively small and small output dust collecting means are generated inside the device. It is possible to efficiently capture the dust before it is released to the outside.

  In this collator, the inner space below the lowermost sheet feeding device is a substantially closed space except for the sheet bundle discharge port, and the suction port is opened in the substantially closed space. Thus, the dust falling to the lower part of the apparatus can be efficiently captured, and the dust can be easily prevented from being discharged to the outside of the apparatus with the discharge of the sheet bundle.

  Further, the above-described collator is a dust collector in which the dust collecting means for connecting with the intake passage is arranged outside the main body casing, and the structure for opening the suction port in the internal space is an intake passage extended from the dust collector. If it is a connecting means to connect the interior to the interior space, the present invention can be easily implemented by simply modifying a general collator and using a general-purpose dust collector that can be fitted with an intake passage such as an intake pipe. It will be possible.

  In this case, the exhaust port is opened at a position and in a direction substantially opposite to the suction port opened in the internal space, in order to exhaust the clean air after the dust collector captures the air containing dust with the filter. In order to provide a connection structure that is connected from the outside, an approximately closed circuit in which most of the sucked air circulates by connecting the intake passage and the exhaust passage and driving the dust collector is used. Or a support structure for supporting the exhaust passage extending from the dust collector at a position where the exhaust port opens downwardly above the opening where the sheet feeding means of the main body casing is inserted. As a result, it is easy to always supply clean air to nearby workers, and most of the exhaust is sucked from the opening in which the paper feeding means of the main body casing is inserted. To substantially circular form an air flow directed from top to bottom in a single, becomes dust generated in the casing is effectively dust collection without leaking out.

  On the other hand, unlike the case of using a dust collector separate from the main body as described above, if the dust collecting means is attached to and integrated with the main body casing, it is advantageous in securing the arrangement space. The collator shall separate the dust collecting means into a suction part having a motor and a fan and a dust trapping part having a filter, and the suction part is arranged on the upper side of the main casing and the dust trapping part is arranged on the lower side of the main casing. If it is installed and connected to each other through the intake passage, it is easy to make the dust collecting means on the side provided with the suction part thinner, and the amount of protrusion on the top plate can be reduced to reduce the overall height of the device. It becomes easy to keep it low.

  Furthermore, in the collator in which the dust collecting means is integrally provided, the dust collecting means is disposed at the lowermost part of the apparatus, and a motor for driving the suction unit is provided in a state of protruding outward from the side surface of the main body casing. If the fan is driven by the driving force transmitting means, the thickness of the dust collecting means inside the apparatus can be further reduced.

  In addition, in the above-described collator, the intake passage is extended to a predetermined height position in the internal space, and a plurality of branch pipes are branched from the intake passage so that at least a plurality of paper feeding means in the vicinity below the sheet flow-out position If the suction ports are opened, the dust can be captured more efficiently.

  In this case, a sheet guide member that guides the sheet fed from the sheet feeding unit downward in the substantially central portion of the internal space is sucked to the side surface with an intake passage formed inside and a branch pipe of the intake pipe connected to the base end side. If the mouth is open, extremely efficient dust collection is possible by capturing dust at a position closest to the place where dust is generated, or an intake passage is formed inside and a branch pipe is formed on the base end side. The suction member connected to the sheet is provided so as to open the suction port below the sheet to be fed in the lateral direction between the base on which the paper feeding unit separating unit is placed and the transport roller on the downstream side. It is the same.

  According to the present invention in which the suction port of the intake passage extending from the dust collecting means is opened in the interior space of the collator, dust is released into the indoor space by collating work using the collator without using a large-scale device. Can be effectively prevented.

  The best mode for carrying out the present invention will be described below with reference to the drawings. The basic configuration and basic operation of the collator itself according to the present invention are almost the same as those of the conventional collator and are well-known techniques, and therefore detailed description thereof is omitted.

  FIG. 1 shows a partial longitudinal sectional view of a collator 1A according to a first embodiment of the present invention. In the present embodiment, a general-purpose dust collector 30A that is separate from the collator 1A is used as the dust collecting means, and the intake pipe 33a at the front end side of the intake hose 31 extended as an intake passage is connected to the side surface of the main body casing. It is characterized in that the suction port 31a is opened in the internal space of the apparatus by being connected to the intake pipe connecting portion 12 made of an annular member provided therethrough.

  Further, in the conventional collator 1I shown in FIG. 10, the internal space of the main body casing is relatively open to the outside including the lower portion, whereas the collator 1A has the lowermost sheet feed. Below the apparatus 2D is a substantially closed space except for the sheet bundle discharge port 11 portion, and the suction port 31a is also opened at a position opposite to the sheet bundle discharge port 11 in the substantially closed space. It has become.

  As a result, most of the dust generated by separation from the paper in the collating operation descends to the lower side of the internal space of the device due to the attraction of the paper feeding operation and the weight of the device itself. Since the suction port 31a of the dust collector 30A is opened there, the dust that has come down can be efficiently sucked and collected. In addition, an air flow is generated between the sheet bundle discharge port 11 and the suction port 31a by opening the sheet bundle at a position opposite to the sheet bundle discharge port 11 where the sheet bundle is discharged at a high speed and a large amount of dust is easily discharged. Therefore, even if the dust collector 30A has a relatively small output, dust existing in the lower side of the internal space can be efficiently sucked and dust can be effectively prevented from being discharged from the sheet bundle discharge port 11.

  FIG. 2 shows a side view of a collator 1B according to a second embodiment of the present invention. In the present embodiment, the collator 1A and the dust collector 30A in the first embodiment are separate from each other, but as a dust collecting means portion 21B formed by installing the dust collecting means on the top plate of the collator, It is characterized by being integrated with the main casing. Then, from the dust collecting means portion 21B, an intake hose 32 as an intake passage having elbows on the proximal end side and the distal end side is extended downward, and is similar to the above in the lowermost sheet feeding device 2D. The lower part is connected to the lower part of the apparatus, which is a substantially closed space.

  By doing in this way, compared with 1st Embodiment, the place which arrange | positions the dust collector 30A becomes unnecessary, and it becomes advantageous in the point which can reduce an installation area. In addition to integrating the dust collecting means portion 21B with the collator 1B as described above, a dust collector having a structure that can be placed on the top plate only when necessary can be provided separately.

  FIG. 3 shows a longitudinal sectional view of a collator 1C as an application example of the collator 1B of FIG. The collator 1C is a further improvement of the above-described collator 1B, and the dust capturing part 210 provided with the filter 211 of the dust collecting means part 21B arranged on the top plate is separated, and the main body casing is formed at the front end side of the intake hose 32. It is characterized by being disposed below the interior space. Thereby, the dust collecting means part 21C from which the dust trapping part 210 is separated can be made thinner, and the overall height of the apparatus can be easily kept lower than that of the collator 1B of FIG.

  Further, the dust catching part 210 has a unit type casing structure provided with a filter 211 inside, which makes it easy to arrange in the lower part of the apparatus, and the lower part can be pulled out from the outside of the apparatus. A dust receiving box 214 is provided to facilitate the processing of dust deposited by the dust captured by the filter 211 falling. In common with the above-described collators 1B and 1C, the intake hose 32 is vertically inserted inside the main body casing of the apparatus, or the wall of the main body casing is a double wall, and the intake hose 32 is formed with the inside as an intake passage. By omitting, it is possible to eliminate the occupation of the space due to the presence of the intake hose 32 and to make the appearance clean.

  FIG. 4 shows a partial longitudinal sectional view of a collator 1D according to a third embodiment of the present invention. The collator 1D is an embodiment in which the dust collecting means portion 21B on the top plate in the collator 1B of FIG. 2 is moved to the lowermost portion of the apparatus as a dust collecting means portion 21D, and the intake pipe 33b is substantially the lower portion of the apparatus. It is characterized by the fact that it opens directly in a closed space and eliminates the need for an intake hose.

  Further, in order to keep the height of the dust collecting means portion 21D low, a plane in which the motor 240 is moved to the side of the fan 230 by transmitting the rotational force to the fan 230 via a power transmission means such as a belt. It has a typical structure. Further, the external drawer type dust receiving box 215 and the lower part of the casing housing the dust receiving box 215 protrude downward into the lower space of the apparatus formed between the casters 60, 60, 60, 60 protruding from the lower surface of the apparatus. Therefore, it is easy to keep the height of the entire apparatus low by keeping the height of the dust collecting means 21D at the lower part of the apparatus low.

  FIGS. 5A and 5B are application examples of the collator 1D of FIG. 4. The motor 240 at the lower part of the collator 1D protrudes outward from the side surface of the main body casing, and the filter 213 is vertically placed along the side surface. The collator 1E is shown as the dust collecting means portion 21E of the embodiment in which the height in the internal space is further reduced. Also in this case, the dust collecting means portion 21E is a unit housed in a single L-shaped casing and is easy to dispose at the time of assembly, and the air passage that has passed through the filter 213. The motor 240 is housed in a casing portion protruding sideways from the side surface of the main body. The sucked air flows downward on the left and right sides of the motor and is discharged from the side of the fan 230.

  In addition, the fan 230 connected by a driving force transmission means such as a belt, together with a lower casing for housing the fan 230, has a structure that protrudes downward into a device lower space formed between the casters 60, 60, 60, 60. Thus, the height of the dust collecting means 21E at the lower part of the apparatus is further reduced. As shown in FIG. 5B, which is a partial sectional view taken along line XX in FIG. 5A, two filters 213 erected along the side surface of the main body casing are provided on both the left and right sides of the motor. A pair of left and right dust receiving boxes 216a and 216b are also provided so that they can be pulled out from the outside.

  FIG. 6 is an application example of the collator 1A of FIG. 1, and an exhaust hose 34 as an exhaust passage is connected to the exhaust port of the dust collector 30B, and the exhaust port 34a is opened in a substantially closed space below the main body casing. The collator 1F is characterized in that a substantially closed circuit in which most of the sucked air circulates is formed as having a structure to be connected. In this case, as shown in the figure, the exhaust port 34a of the exhaust hose 34 is arranged at a position and orientation facing the suction port 31a of the intake hose 31, so that most of the sucked air circulates to form a substantially closed circuit. Thus, dust existing at the lower part of the apparatus can be efficiently sucked, and exhaust to the outside can be hardly discharged. In addition, by providing the valve 340 for adjusting the air flow rate on the base end side of the exhaust hose 34, the circulating air amount can be easily adjusted.

  FIG. 7 shows another application example of the collator 1A of FIG. 1, in which an exhaust hose 35 is connected to the exhaust port of the dust collector 30B, and this is extended above the top plate of the apparatus so that each sheet feeding device of the main body casing is provided. A collator 1G is characterized in that it is supported by a support member 44 so that its exhaust port opens downwardly above the opening where 2C is inserted. As a result, the exhaust gas descends along the side surface of the casing having the opening of each sheet feeding device 2C, and the exhaust gas is sucked through each opening, and the airflow from the top to the bottom reaching the suction port 31a in the main body casing. Therefore, dust generated in the main body casing is efficiently collected without leaking to the outside, and a large dust collecting effect can be expected even if the dust collector 30B has a low output. it can. Further, exhaust air is exhausted near the front of the worker working around the apparatus, and clean air from which dust has been removed can be supplied to the worker to provide a good working environment. In this case, if the exhaust pipe 39 provided on the distal end side of the exhaust hose 35 has a T-shape as shown in the figure and exhausts in two directions across the device, almost all openings of the main casing are opened. The exhaust gas is supplied to the unit, and can be applied to two workers at the same time.

  FIG. 8 shows a longitudinal sectional view of a collator 1H according to the fourth embodiment of the present invention. The collator 1H has a connection structure that is connected to a dust collector 30C in which two suction portions are provided in parallel by an intake passage, and the intake hose 36 extending from the first suction portion is connected to the collator 1A in FIG. Similarly, the suction hose 37c is opened in the substantially closed space at the lower part of the apparatus, and the intake hose 37 extending from the second suction part is connected to an intake pipe 38 extending substantially upward at the substantially central part of the main body casing. Each intake passage is formed.

  Further, the intake pipe 38 has a plurality of branch pipes 380 that open a suction port below the pair of rollers 70 and 70 that feed the paper between the paper feeding devices 2C and 2C downward. It is characterized in that it can be sucked before the dust generated when the paper is delivered from 2C is diffused.

  By doing in this way, it becomes possible to effectively prevent dust from leaking out from the middle / upper part of the main body casing, which is a relatively open space for disposing each paper feeding device 2C, and discharging dust. The prevention effect is further improved. In this case, it is also effective to provide the branch pipes 380 for every stage of all the paper feeding apparatuses 2C, or to provide them for every other stage.

  Further, as an application example of the branch pipe 380 arrangement method, as shown in the enlarged partial perspective view of FIG. 9A, rollers 70, 70 for feeding the sheet sent from the sheet feeding device 2C downward in the center of the apparatus. The paper guides are arranged in parallel to the roller shafts below to guide the paper downward, and have a tubular structure with an intake passage inside, and a branch pipe 380 is connected to the base end side to close the terminal side. As one example, if the paper guides 50a and 50b are provided with suction ports 51, 52, 53,... At predetermined intervals in the length direction on one side surface, dust can be reliably suctioned across the width direction of the paper. It will be a thing. In this case, if the suction ports 51, 52, 53,... Are gradually provided with increasing distance from the connection position of the branch pipe 380, the suction force of the suction ports can be easily aligned.

  Alternatively, as shown in the enlarged partial longitudinal cross-sectional view of FIG. 9B, a base is placed between the shelf-like base 40 on which the separating unit of the paper feeding unit 2C is placed and the conveying roller 75 on the downstream side. A suction member 55 formed by connecting a branch pipe 380 to the end side and forming an intake passage parallel to the roller axis of the transport roller 75 is formed so as to open a suction port 56 below the sheet fed in the lateral direction. It is the same even if provided.

  In this case, it is possible to make the suction port 56 slightly downward from the horizontal direction instead of upward as shown in the figure, but by doing so, it is possible to avoid the trouble of the dropped paper piece falling and blocking the suction port 56. It will be easy. The same effect as described above can be expected by providing a plurality of suction ports 56 at predetermined intervals in the width direction of the sheet or by gradually increasing the distance from the connection position of the branch pipe 380. 8 and 9 can be applied to all the embodiments described above, and the same effects can be exhibited in addition to the effects of the respective embodiments. Is.

  As described above, due to the present invention that can be implemented with a relatively simple configuration with minimal increase in arrangement space and cost increase, dust is discharged into the indoor space by collator collation work. It is now possible to effectively prevent troubles.
