Description

  The present invention is a soft cover that polishes the book's booklet's small edge, top and bottom, etc. in a so-called soft cover book that can bend together with the book's main body so that the book / book's front and back cover can be bent with the book's main body. The present invention relates to a polishing machine for books.

  Traditionally, many of the various books displayed and sold at bookstores have been distributed in a consignment sales format. Books that have not been sold even after the consignment period has passed are sold at brokerage stores. They are picked up and distributed to other bookstores that need them, or they are stored in preparation for reshipment. However, when redistributing, if the book, especially its mouthpiece, top and bottom, etc. is damaged by sunburn, fine dust adhesion, etc. at the time of sale / storage, etc. In some cases, it is evaluated as a secondhand book without being handled, and it is not preferable for both a seller and a buyer that a new book is evaluated as a secondhand book.

  In addition, due to the peculiarity of books, it is a common practice for subscribers to sell what has been read as secondhand books to so-called secondhand bookstores and sell them again as secondhand or secondhand books at secondhand bookstores. When selling again as secondhand books etc., the book paper, especially the small edge on the opposite side of the back cover, the top and bottom top and bottom parts, etc., may be overlapped with the book paper, and it will be in a state of light dirt with fine dust attached There are many.

  For this reason, when these new books are shipped again or when secondhand books are sold, the edge and top of the book are polished and cleaned to restore the fresh state at the time of publication, thereby improving the unit price of the product. This polishing operation is performed by, for example, rubbing and rubbing a paper file on each of the front end and the top of the book, which is very troublesome to perform manually.

  In view of these points, a book polishing apparatus shown in Patent Documents 1 and 2 and a book polishing apparatus shown in Patent Document 3 have been proposed. In Patent Document 1, polishing is performed by sliding each small edge, heaven, and ground of a book sandwiched with a small edge, a heaven, and a ground with an abrasive that is a group of randomly cut sandpapers arranged in a wing shape. It is made to do. In Patent Document 2, a book holder with both sides and the bottom opened is set on a mounting table in which upper and lower through-holes are formed, and endless ones corresponding to both sides of the window hole and the book holder are set. The book in the book holder is polished by the sandpaper belt. In Patent Document 3, a book fixing mechanism that presses and holds or releases a plurality of paper cover books is provided, and the book is released by pressing and holding the book as the elevating table that moves up and down below the book fixing mechanism rises. The lower surface of the paper table is aligned and sandwiched again, and then the lifting table is lowered, and the polishing roller rotates and slides against the lower surface of the paper cover book to polish it. By repeating the release and polishing by the polishing roller while rotating the paper cover book by 90 degrees, the edge, top and ground of the paper cover book are polished.

Registered Utility Model No. 3029551 Registered Utility Model No. 3064545 Japanese Patent No. 3530131

  However, in the polishing apparatuses shown in these conventional patent documents and the like, in Patent Document 1, the troublesome hand that has to be reset so that the surface to be polished such as the fore, top, and ground of the book to be polished must be replaced each time. Requires work. In Patent Document 2, not only the book mouth, top, ground, etc. must be aligned and stored in the book holder on the opening hole on both sides, but also on the book located at the end of the window hole and opening. On the other hand, the edge of the window hole or the edge of the opening where the step is generated may become an obstacle, and the sandpaper belt may not reach the surface to be polished sufficiently and may not be rubbed. In Patent Document 3, it is necessary to accurately control the pressing and clamping movement of the book in the book fixing mechanism, the lifting movement of the lifting table, the reciprocating movement of the polishing roller, and the like. If the pressing and clamping force is too strong, the small book may not fall on the lifting table surface and the lower surface may not be aligned when it is released, making reliable polishing difficult. It can happen.

  Therefore, the present invention was created in view of various circumstances that existed in the past, and its purpose is to be able to reliably process a large amount of each of the fore edge and top and bottom portions of a soft cover book, and there is no variation.

And a pressing means 55 for pressing the book B pushed into the book storage chamber 53 from above and below, and an elevating means 57 for lifting and lowering the book storage chamber 53 along the guide frame 51. .
The book return mechanism 60 moves forward and backward in a direction orthogonal to the transport direction in the transport mechanism 20 and advances to the entrance / exit transport unit 24 side of the transport mechanism 20 and presses against the book B in the polishing book lift mechanism 50. A return pressing plate 63 connected to the slide rod 62 can be used.
The book turning mechanism 70 includes a support rod (76, 77) that is provided in a standing shape below each of the entrance / exit conveyance units 24 in the conveyance mechanism 20, and that raises / lowers the book B from below and turns the book B above the entry / exit conveyance unit 24. The up-and-down turning part (75, 78) and the pressing part that moves up and down to oppose the upper end of the support rod (76, 77) in the vertical direction above the support rod (76, 77) so as to press the book B from above. (79, 81).
The discharge mechanism 90 is a discharge conveyor 91 that circulates and drives on the inside and outside of the discharge side (5), and a discharge board that moves up and down vertically and moves back and forth so that the book B on the transport mechanism 20 is moved and discharged onto the discharge conveyor 91. 92.

In the soft cover book polishing machine according to the present invention configured as described above, while the book B is intermittently transferred by the transfer mechanism 20 that intermittently advances and retreats at the front position of the adjacently arranged polishing mechanism 30, the transfer mechanism 20 At the time of intermittent stop, the book B on the transport mechanism 20 is sequentially fed toward the polishing mechanism 30 with the unpolished portion thereof, and is scraped by the polishing band 37. Meanwhile, the transport mechanism 20 is moved backward, the polished book B is returned to the transport mechanism 20 in the retracted position, the book B is turned during the transport in which the transport mechanism 20 is advanced again, and the book B is turned after the turn. Is repeatedly sent to the polishing mechanism 30 on the next stage, and the fore edge, top, and ground of Book B are sequentially polished.
The books B to be polished are intermittently conveyed from the input port 2 on the input side to the discharge port 5 on the discharge side as a single processing group that is flat and collected in a predetermined number of books, and is polished for each processing group. By moving a series of processes that are fed and polished from the transport mechanism 20 to each mechanism 30 and then returned to the transport mechanism 20 after polishing so that the next process is performed collectively in a plurality of processing groups, A large amount is processed for each processing group.
The conveyance mechanism 20 is intermittently stopped at the front position of each polishing mechanism 30, and the book moving support mechanism 40 feeds the polishing book lifting mechanism 50 from the conveyance mechanism 20 to the polishing book lifting mechanism 50 on the entrance / exit conveyance section 24 at the time of the stop. 50 is moved up and down by rubbing against the polishing band 37 of the book B in a state of being pressed up and down, the book B is returned to the transport mechanism 20 after the retraction by the book return mechanism 60 after rubbing, and the subsequent polishing of the next stage is performed thereafter. The unpolished portion of each of the polishing mechanisms 30 is changed while the direction of the unpolished portion of the book B is changed with respect to each of the polishing mechanisms 30 by turning the direction of the book B with respect to the polishing mechanism 30 on the next stage during conveyance to the mechanism 30. Are successively and sequentially polished.
In the intermittent advance / retreat of the transport mechanism 20, the book B is sequentially transported from the input mechanism 10 to the discharge mechanism 90 side through the next-stage polishing mechanism 30 during the forward movement, and the book B after polishing is discharged by the discharge mechanism 90. Let At the time of retreat, a new unpolished book B is loaded and held by the loading mechanism 10, and the loading / unloading transport located on the next-stage side that is empty due to the book B being fed into each polishing mechanism 30. The part 24 is positioned in front of the preceding polishing mechanism 30, prepared for transporting the book B to the polishing mechanism 30 on the next stage, and placed on standby.
Further, when the transport mechanism 20 moves forward, the book B is transported, and when the book B is fed into the polishing mechanism 30 side, that is, the polishing book lift mechanism 50 by the book movement support mechanism 40 when the transport mechanism 20 stops, the subsequent polishing book When the book B is polished by the polishing mechanism 30 as the elevating mechanism 50 moves up and down, the transport mechanism 20 is in the backward operation and prepares for a new book B to be inserted. Further, when the transport mechanism 20 moves forward, the book B on the front-entry entrance / exit transport unit 24 in the transport mechanism 20 reaches the discharge mechanism 90 position, and the book B is inserted, polished, and discharged by being discharged. Process smoothly.
Vertical movement, advance / retreat of the input board 12 in the input mechanism 10, advance / retreat of the press plate 43 in the book movement support mechanism 40, advance / retreat of the return press plate 63 in the book return mechanism 60, advance / retreat of the discharge board 92 in the discharge mechanism 90. Etc., the movement for the next stage processing of the book B of the one processing group of the flat stack is made smooth, and the unpolished portions that are overlapped are aligned and sent to the polishing mechanism 30 side.
The pressing means 55 in the polishing book lifting / lowering mechanism 50 presses the book B from above and below when the polishing book lifting / lowering mechanism 50 moves up and down in a state where the unpolished portion of the book B is scraped against the surface of the polishing band 37 of the polishing mechanism 30. This prevents the book B from being displaced, returned or retracted by the rubbing action, and reliably polishes the unpolished portion.
In the book turning mechanism 70, the pressing and clamping from the top and bottom of the book B by the support rod (76, 77) and the pressing portion (79, 81) are performed when the direction of the book B is turned by the up-and-down turning portion (75, 78). The positional deviation between the books B is prevented, and the unpolished portions of the books B of one processing group are turned to be aligned and sent to the polishing mechanism 30 side.

  Since the present invention is configured as described above, the front and back papers are smooth with the book body when polishing the fore edge and top and bottom of the soft cover book. A large amount of processing can be performed collectively, and the polishing processing has no variation and can be processed uniformly. In addition, a predetermined number of books in a flat stack can be processed together for each processing group, and a series of processing for each processing is processed continuously and in parallel, so there is no time loss and the work efficiency is dramatically improved. Can be improved.

  In other words, in the present invention, the loading mechanism 10 that loads the book B, the polishing mechanism 30 that is adjacently disposed so as to polish the fore edge, top, and ground of the book B by the polishing band 37, and the polishing mechanism 30 The book is disposed at the front position of each of the transport mechanism 20 that intermittently transports the book B at the front position, the book movement support mechanism 40 that moves the transported book B to the polishing mechanism 30 side, and the polishing mechanism 30. A polishing book lift mechanism 50 that sandwiches B from above and below and rubs it up and down on the surface of the polishing band 37; a book return mechanism 60 that returns the book B after polishing to the transport mechanism 20; This is because it includes a book turning mechanism 70 that turns the polishing unit so as to turn to the next polishing mechanism 30 side during conveyance, and a discharge mechanism 90 that discharges the book B after polishing. Input In the process leading to the discharge, small portions of the books B, top part, each land unit automatically in large quantities, can be reliably polished.

  In addition, since the polishing process is performed for each book B of one processing group gathered in a predetermined number of books in a flat stack, and the polishing is processed in parallel at each stage, it can be processed continuously in large quantities without time loss, Work efficiency can be dramatically improved.

  Since the conveyance mechanism 20 is provided with an entrance / exit conveyance section 24 that is partitioned and formed in correspondence with the interval between the adjacent polishing mechanisms 30 on the conveyance table 22 that is intermittently advanced and retracted, each of the polishing mechanisms 30 when the conveyance mechanism 20 moves forward. The book B can be transported and positioned at the front position of the front, and the next-stage entrance / exit transport section 24 when the previous-stage book B to be transported to the next-stage polishing mechanism 30 is returned during the backward operation can be prepared for standby in front of the polishing mechanism 30. In addition, it can be continuously processed by conveyance by intermittent advance and retreat of the conveyance mechanism 20.

  Since the polishing mechanism 30 includes a circulating polishing band 37, the polishing book lifting / lowering mechanism 50 causes the book B to be polished by the polishing book lifting / lowering mechanism 50 in any portion of the book B that is abutted against the polishing band 37. As B is raised and lowered, it can be rubbed and continuously polished.

  In the book movement support mechanism 40, the pressing plate 43 that advances and retreats in a direction orthogonal to the conveyance direction by the conveyance mechanism 20 presses the book B on the conveyance mechanism 20 and moves it to the polishing mechanism 30 side. Can be smoothly stored in the book storage chamber 53 of the polishing book lifting / lowering mechanism 50 disposed at the position, and can be positioned at the polishing position by the polishing band 37 of the polishing mechanism 30.

  The polishing book lifting mechanism 50 is provided with pressing means 55 that presses the book B from the vertical direction in the book storage chamber 53, so that the polishing book lifting mechanism 50 is lifted and lowered by the lifting means 57. Is pressed against the polishing band 37, the portions to be polished of the book B are not displaced from each other or retreated, and the portion to be polished can be reliably applied to the surface of the polishing band 37 and rubbed.

  In the book return mechanism 60, the return pressing plate 63 that advances and retreats in a direction orthogonal to the transport direction by the transport mechanism 20 reliably returns the book B in the book storage chamber 53 onto the transport mechanism 20, and during polishing. Since the transport mechanism 20 is in the retracted position, the returned book B is returned onto the empty entrance / exit transport unit 24 corresponding to the position of the next polishing mechanism 30 in the transport mechanism 20. Once the book B is returned, it can be transported to the front position of the next polishing mechanism 30 and can be kept waiting at that position.

  Since the book turning mechanism 70 is provided at the position of the entrance / exit transport unit 24 of the transport mechanism 20, the book B is oriented while the transport mechanism 20 is transported so that the unpolished part is directed to the polishing mechanism 30 side of the next stage. When the position reaches the front position of the next polishing mechanism 30, the unpolished portion can be reliably polished by the book movement support mechanism 40 and the polishing book lifting mechanism 50.

  In the discharge mechanism 90, since the book B after polishing on the input / output transport unit 24 at the final stage position of the transport mechanism 20 is pressed by the discharge plate 92 and moved onto the discharge conveyor 91, a series of polishing work is completed. It is only necessary to sort out the books B discharged in this manner, and the work efficiency can be greatly improved.

  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the figure is a main frame constructed of a predetermined hollow square steel material or the like, and front and rear sides of the main frame 1 The left and right side surfaces and the ceiling surface are covered with, for example, a transparent panel so that paper dust and paper waste are not scattered around. On the front surface of the main frame 1, a soft cover book B to be polished through a slot 2 formed at one end of the main frame 1 is loaded and set for each processing group having a predetermined number of books. A discharge area through which the polished book B is discharged is formed through the discharge opening 5 formed at the end of the paper, and a loading mechanism 10, a conveyance mechanism 20, and a polishing mechanism 30 (30 </ b> A, 30 </ b> B, 30C), the booklet B support mechanism 40, the polishing book lifting mechanism 50, the book return mechanism 60, the book turning mechanism 70, the discharge mechanism 90, etc., polish each of the small edge part and the top part of the book B so as to adjust the appearance. ing. In the description of the present embodiment, the reference numerals 30A, 30B, and 30C are used to distinguish the polishing mechanism 30 itself, but the reference numeral 30 is used when they are not distinguished.

  As shown in the figure, at the front part of the main frame 1, there are three first, first, and third parts that polish the fore edge, top, or ground part of the book B between the input mechanism 10 and the discharge mechanism 90, respectively. 2. The third polishing mechanism 30 (30A, 30B, 30C) is adjacently arranged at equal intervals, and on the front surface of these polishing mechanisms 30, a book B to be polished by each of the polishing mechanisms 30, that is, A polishing book raising / lowering mechanism 50 for raising and lowering the books B of the three treatment groups in a lump so as to be rubbed against the polishing band 37 of the polishing mechanism 30 is provided. Further, the book B, that is, the books B of the three processing groups are collectively moved from the loading position to the position of the first polishing mechanism 30A in parallel with the polishing book lifting / lowering mechanism 50 that is in front of the polishing mechanism 30. Intermittent conveyance from the polishing mechanism 30A position to the second polishing mechanism 30B position, from the second polishing mechanism 30B position to the third polishing mechanism 30C position, and further from the third polishing mechanism 30C position to the discharge mechanism 90 position side, respectively. A transport mechanism 20 is disposed.

  Further, the transport mechanism 20 incorporates a book movement support mechanism 40 that moves the book B of one processing group on the transport mechanism 20 to the polishing mechanism 30 side and to the discharge mechanism 90 side. The book B after being transported to the front position of the adjacent next-stage polishing mechanism 30 is moved from the transport mechanism 20 to the polishing mechanism 30 side. Further, the book turning mechanism 70 is also incorporated, and the book turning mechanism 70 is activated during the batch conveyance by the conveyance mechanism 20 of the book B that has been returned from the polished book lifting / lowering mechanism 50 onto the conveyance mechanism 20 after the polishing is completed. In order to polish the top part or the ground part after the polishing of the fore edge by the book turning mechanism 70, and the ground part or the top part after the finishing of the top part, The direction of the book B in the treatment group is turned by a predetermined angle, and after finishing the polishing of the fore edge portion, the top or the ground portion which is an unpolished polishing portion is set to the second and third polishing mechanisms 30B on the next stage side, It is directed to the 30C side.

  That is, as shown in FIGS. 3 and 4, the first, second, and third polishing mechanisms 30A, 30B, and 30C that are sequentially arranged adjacent to each other at the front portion in the main frame 1 The book B is intermittently transported to the front position of each polishing mechanism 30 by the transport mechanism 20 in order to polish each of the fore edge, top, and ground of the book B in one processing group, and the book moving support is supported for each polishing mechanism 30. The book B on the transport mechanism 20 is moved into the polishing book lifting mechanism 50 by the mechanism 40 and polished by the lifting and lowering movement by the polishing book lifting mechanism 50 so as to be rubbed against the polishing band 37 of each polishing mechanism 30. After polishing, the book B is returned from the polished book lifting mechanism 50 to the transport mechanism 20 by the book return mechanism 60, and the unpolished portion of the book B is moved to the polishing mechanism 30 side by the book turning mechanism 70 while being transported by the transport mechanism 20. When the direction is changed and the transport mechanism 20 transports the second and third polishing mechanisms 30B and 30C adjacent to each other to the front position, the book movement support mechanism 40 moves the book B into the next polishing book lifting mechanism 50 again. Let After the movement, the top part and the ground part of the book B are similarly polished, and when the book B is returned onto the transport mechanism 20, the polishing returned from the third polishing mechanism 30 </ b> C by the transport operation of the transport mechanism 20. The finished book B is carried out onto the discharge mechanism 90.

  Therefore, the input mechanism 10, the three polishing mechanisms 30, and the discharge mechanism 90 are arranged adjacent to each other with an equal interval between them, and are arranged on the front surfaces of the polishing mechanisms 30 corresponding to these adjacent arrangements. A total of three polishing book lifting / lowering mechanisms 50 are arranged, and the conveyance mechanism 20 that intermittently moves back and forth between the loading position and the discharging position similarly corresponds to the adjacent arrangement interval of the polishing mechanism 30 and the discharging mechanism 90. Four book movement support mechanisms 40 and three book turning mechanisms 70 are installed and arranged (see FIG. 1).

  Next, each of these mechanisms will be described sequentially. The input mechanism 10 in the input area is circulated and driven inside and outside the input port 2 of the main frame 1 and separates a predetermined number of books B stacked in a single processing group to be polished for each book B in one processing group. And a loading conveyor 11 that carries in and a loading board 12 that moves up and down to move and move on the conveying mechanism 20 and moves forward and backward.

  A set stand 3 on which books B to be polished are set in a flat stack by an operator is provided at the input port 2 in front of the input conveyor 11 in the input mechanism 10. When the front end of the input conveyor 11 is continuous with the rear end of the set table 3 and the book B for each processing group on the set table 3 is pushed out onto the input conveyor 11 so that the input conveyor 11 is transported. It is designed to be fed to the 20 side.

  The input board 12 is an input base provided on the upper part of the main frame 1 so that the book B fed by the input conveyor 11 moves forward and backward by the operation of an advance / retreat cylinder such as an air cylinder at a position near the rear end side portion of the transport mechanism 20. Similarly, an up / down cylinder such as an air cylinder is provided and connected to a cylinder rod of the up / down cylinder. A stack of books B in one processing group is pushed onto the transport mechanism 20 from the rear side.

  In addition, the book B set flat on the set stand 3 is assumed to be positioned by an operator so that the input conveyor 11 side becomes a back cover. In this way, when the input conveyor 11 and the input board 12 are pushed onto the transport mechanism 20, the spine cover of the book B is directed to the opposite side of the polishing mechanism 30 disposed on the side of the transport mechanism 20. In other words, the fore-edge portion of the book B is directed to the rear side in the insertion direction.

  The transport mechanism 20 moves forward so as to transport the small edge, top, or ground of the book B for each processing group to be polished to the next polishing mechanism 30 side, and retreats during polishing. Then, the apparatus waits to accept each of the books B retracted and returned from the polishing mechanism 30 after the polishing is completed at the front-side portion of the empty position, and the discharging position by the loading mechanism 10 and the discharging position by the discharging mechanism 90 after the polishing is completed. The book B for each processing group is intermittently conveyed at once.

  That is, the transport mechanism 20 itself is a front part of the polishing mechanism 30, and a transport base 22 that intermittently advances and retracts between the loading position of the book B from the loading mechanism 10 and the discharging position of the book B after the polishing is completed, and this transport. An entrance / exit transport unit 24 is provided on the top surface of the transport table 22 so as to roll with respect to the polishing mechanism 30 side in a direction orthogonal to the transport direction on the top surface of the base 22 (see FIG. 6).

  3 and 6, the book movement support mechanism 40 is transported when the book B having an unpolished portion for each processing group transported by the transport mechanism 20 is positioned in front of each of the polishing mechanisms 30. It is assumed that the book B on the loading / unloading conveyance unit 24 of the conveyance table 22 in the mechanism 20 is sent into the polishing book lifting / lowering mechanism 50 with the unpolished part side facing the polishing mechanism 30. Therefore, the slide which advances / retreats along the guide rail 41 mounted between the support columns 25 along the front-rear direction of the support columns 25 at the four sides of the entrance / exit conveyance unit 24 (along the direction orthogonal to the conveyance direction in the conveyance mechanism 20). It consists of a rod 42 and a pressing plate 43 connected to the slide rod 42 so as to be pressed against the book B on the entrance / exit transport unit 24 along the vertical direction. The slide rod 42 is moved back and forth by, for example, an air cylinder, and when the book B to be polished is positioned in front of each of the polishing mechanisms 30, the book B on the entrance / exit transport unit 24 is polished by the slide rod 42 via the pressing plate 43. It is pushed into a polishing book lifting / lowering mechanism 50 arranged in front of the mechanism 30.

  1, 2, and 8, the polishing book lifting / lowering mechanism 50 is disposed immediately before each of the polishing mechanisms 30, and is a small edge portion that is an unpolished portion of the book B pushed in by the book movement support mechanism 40. The side, the top, or the ground side is lifted and lowered while being in contact with the polishing band 37 of the polishing mechanism 30. That is, polishing is performed by moving up and down with the outer edge of the polishing band 37 to be circulated pressed against the outer edge of the book B to be polished, the top or the ground, and rubbing with the polishing band 37. The polishing book lifting mechanism 50 itself is supported in the main frame 1 so as to be vertically movable along the guide frame 51 and accommodates the books B for each processing group. A book storage chamber 53, a pressing means 55 for pressing one processing group of books B pushed into the book storage chamber 53 from above and below, and an elevating means 57 for moving the book storage chamber 53 up and down along the guide frame 51. Is provided.

  The guide frame 51 is erected in, for example, a pair in the polishing mechanism 30 along the vertical direction immediately before the polishing mechanism 30 in the main frame 1 and meshes with a guide rail 52 provided on the front surface thereof. In this way, the book storage room 53 is arranged.

  The book storage chamber 53 is formed by connecting the four corners of upper and lower side plates 54A and 54B, which are substantially rectangular in a plane arranged vertically, with upright support columns, and the book in front of the polishing mechanism 30 through the opened front and rear sides. B is put in and out and the accommodated book B is directed to the polishing band 37 so that the unpolished part is rubbed.

  In the illustrated example, the pressing means 55 is an air cylinder located on the polishing plate 30 side of the upper plate 54A of the book storage chamber 53, and the pressing piece 56 connected to the lower end of the cylinder rod is lowered to 1 The upper surface of the book B in the processing group is pressed to prevent misalignment of the book B during rubbing.

  Similarly, in the illustrated example, the elevating means 57 is an air cylinder erected on the bottom of the main frame 1, and the lower plate 54B of the book storage chamber 53 is connected to the upper end of the cylinder rod so that the cylinder rod can be moved up and down. The book storage chamber 53 is moved up and down. By raising and lowering the book storage chamber 53 in this way, the book B of one processing group pressed and sandwiched from above and below by the pressing means 55 is brought into contact with the surface of the polishing band 37 of the polishing mechanism 30 to polish a predetermined unpolished portion. The band 37 is used for rubbing.

  The book B after the polishing process is returned by the book return mechanism 60 from the polished book lifting / lowering mechanism 50 onto the entrance / exit transport unit 24 of the transport mechanism 20. That is, the book return mechanism 60 is disposed in the front portion of the main frame 1 below the polishing mechanism 30 as shown in FIG. 2 and is mounted on the main frame 1 so as to be orthogonal to the transport direction in the transport mechanism 20. The slide rod 62 that advances and retreats along the guide rail 61 and the book B in the book storage chamber 53 in the polishing book lifting mechanism 50 are pressed against the slide rod 62 so as to advance toward the entrance / exit transport unit 24 side of the transport mechanism 20. And a return pressing plate 63 connected so as to extend along the line. The slide rod 62 is moved back and forth by, for example, an air cylinder. When the polished book B is lowered to the lower side of the polishing band 37 of the polishing mechanism 30, the slide rod 62 causes the inside of the book storage chamber 53 to pass through the return pressing plate 63. The book B is pushed back onto the entrance / exit transport unit 24 of the transport mechanism 20.

  In the return pressing plate 63 of the book push-back mechanism 60, the standby position before the push-back operation is set immediately below the polishing position for the book B by the polishing band 37 of the polishing mechanism 30. By doing so, when the book B is pushed into the polishing book lifting mechanism 50 by the book movement support mechanism 40, the polishing book lifting mechanism 50 can be lifted and stopped corresponding to the position to be polished. The rubbing operation of the polishing band 37 against the surface to be polished can be made smooth and reliable.

  The book B of one processing group returned to the entrance / exit transport unit 24 by the book return mechanism 60 is incorporated in the entrance / exit transport unit 24 while being transported to the adjacent next-stage polishing mechanism 30 by the transport mechanism 20. The book turning mechanism 70 is turned along the horizontal direction so that the unpolished portion of the book B is directed to the polishing mechanism 30 side. In other words, the book B whose fore edge has been polished by the first polishing mechanism 30A is turned to the left at 90 degrees so that, for example, the top is directed to the second polishing mechanism 30B, and the second polishing mechanism 30B The book B whose part has been polished is turned to the left or right at 180 degrees so that, for example, the ground part is directed to the third polishing mechanism 30C side. In addition, since the fore edge, top, and ground of the book B need only be sequentially polished by the three polishing mechanisms 30, the turning direction, the turning angle, and the like are appropriately selected depending on the polishing order. The polishing order is not limited to the above.

  That is, as shown in FIG. 9, the book turning mechanism 70 includes a turning mechanism chamber 71 formed by sectioning with a shape steel or the like below each of the entrance / exit transporting sections 24 in the transport mechanism 20, and the turning mechanism chamber 71. The up-and-down turning part (75, 78) provided with a support rod (76, 77) that is provided in a stand-like shape and raises and lowers the book B from below and turns around the entrance / exit transport part 24, and the support rod (76, 77). ) And the upper end of the support rod (76, 77) opposite to each other in the vertical direction, and a pressing portion (79, 81) that moves up and down to press the book B from above.

The upper pressing plate 79 that holds the book B from the upper and lower sides together with the lower pressing plate 77 is provided.

  The support frame column 72 is suspended from the support plate 26 itself below the support plate 26, and has a size and a width sufficient to accommodate the drive portion of the turning means 75 together with the support base 73.

  The turning means 75 shown in the figure is a turning motor provided on the support base 73, and is formed by connecting a turning board 76 to the output shaft of this turning motor. The turning board 76 is predetermined by the rotation of the turning motor. For example, it turns around 90 degrees or 180 degrees to the left or right. The turntable 76 has a turning surface that extends along the horizontal direction, and is supported from the periphery by an appropriate support so that it can be smoothly turned without rattling during the turning operation.

  The lower pressing plate 77 is, for example, arranged at the upper end of a cylinder rod of an elevating cylinder 78 provided on the turntable 76, and the entrance / exit conveyance unit through the entrance / exit 27 formed in the central portion of the entrance / exit conveyance unit 24. 24 is moved up and down by a lifting cylinder 78 so as to be positioned on or below the upper surface. By this up-and-down movement, the book B is lifted to the upper surface of the entrance / exit transport unit 24, and after the turn, the book B is lowered and is placed on the entrance / exit transport unit 24 so as to be immersed below the entrance / exit transport unit 24.

  The upper pressing plate 79 is disposed at the lower end of the cylinder rod of the pressing cylinder 81 disposed on the support plate 26, and the operation of the pressing cylinder 81 in response to the lower pressing plate 77 lifting the book B by the elevating cylinder 78. Thus, the book B is pressed from above, and the book B is held together with the lower pressing plate 77.

  Further, when the turning plate 75 is rotated by the turning means 75 while the book B is held between the lower pressing plate 77 and the upper pressing plate 79, the lower pressing plate 77 or the upper pressing plate 79 is at least one of the books B The abutting portions that abut on the upper and lower surfaces rotate freely so that they follow the rotation direction.

  In the book turning mechanism 70, a lower pressing plate 77 that moves up and down is provided on the turning table 76 that rotates, and a turning mechanism that rotates on the lifting mechanism that moves up and down can be arranged. In short, it is only necessary that the book B of one processing group returned by the book return mechanism 60 from the polishing book lifting / lowering mechanism 50 is turned on the entrance / exit transport unit 24 and the unpolished part is directed to the polishing mechanism 30 side.

  The turning of the book B by the book turning mechanism 70 is performed while the book B is transported to the front position of the next polishing mechanism 30 by the transport mechanism 20, and the unpolished portion side of the book B becomes the next polishing mechanism 30. When it is directed, it is fed into the polishing book lift mechanism 50 by the book movement support mechanism 40 and is polished by the polishing mechanism 30 as it moves up and down. When the polishing of the fore edge, top, and ground of the book B is finished by the third polishing mechanism 30C at the final stage, the book is returned onto the entrance / exit transport unit 24 at the final stage part of the transport mechanism 20 by the book return mechanism 60. B is returned. The book B returned to the transport mechanism 20 is discharged to the outside by the discharge mechanism 90 through the discharge port 5 of the main frame 1.

  The discharge mechanism 90 is arranged and configured to correspond to the entrance / exit transfer portion 24 portion of the final stage portion of the transfer mechanism 20 when the transfer mechanism 20 is at the foremost position in the transfer direction. As shown in FIG. , A discharge conveyor 91 that is provided from the side position of the transport mechanism 20 to the outside of the main frame 1 through the discharge port 5 and circulates and drives inside and outside the discharge port 5, and one processing group on the transport mechanism 20. In order to move and discharge the book B onto the discharge conveyor 91, a discharge board 92 that moves up and down and moves back and forth is provided. A discharge table 93 is interposed between the rear end of the discharge conveyor 91 and the side of the transport mechanism 20.

  The discharge plate 92 is provided at the rear position of the discharge port 5 in the main frame 1 with a vertically moving cylinder, such as an air cylinder, on a discharge base provided at the upper part of the main frame so as to advance and retreat by the operation of an advance / retreat cylinder such as an air cylinder. It is provided by being linked to the cylinder rod of this vertical movement cylinder, and moves forward while descending by the operation of these advance and retreat cylinders and vertical movement cylinders, and a book B of one processing group on the discharge table 93 is provided. It is sent out onto the discharge conveyor 91.

  When the transport mechanism 20 is in the forward position and the entrance / exit transport unit 24 of the final stage portion reaches the rear position of the discharge conveyor 91, the book moving mechanism 40 is operated. The polished book B on the transport unit 24 is pushed onto the discharge table 93. Then, the vertically moving cylinder and the advancing / retreating cylinder are operated to push the polished book B on the discharge table 93 onto the discharge conveyor 91 and place it on the discharge conveyor 91. Is discharged out of the main frame 1.

  Further, in the main frame 1, a dust collecting device is arranged in the vicinity of the polishing operation region by the polishing mechanism 30, and for example, a duct-shaped dust collecting port in this dust collecting device faces the polishing operation region. In addition, consideration is given so that paper dust or the like generated during polishing is not scattered around.

  Next, the operation of the polishing machine for soft cover books according to the present invention when polishing the fore edge, top, and ground of book B, which is a so-called soft cover book, will be described. First, a predetermined number of books B to be polished are stacked into one processing group, and each processing group is set on the setting table 3 in front of the input port 2 and the input mechanism 10 is input via the input conveyor 11. As the board 12 moves forward / backward / upward / downward, it is inserted and pushed into the entrance / exit transport section 24 of the last stage part of the transport mechanism 20 that is retracted to the rear position for each book B in one processing group. Then, the transport mechanism 20 moves forward and transports the book B to the front position of the first polishing mechanism 30A that is polished in the first stage (see FIG. 10A). The transported book B is positioned in front of the first polishing mechanism 30A by the pressing plate 43 of the book movement support mechanism 40 positioned in front of the polishing mechanism 30 together with the book B by being incorporated in the transport mechanism 20. It is pushed into the book storage chamber 53 of the polishing book lifting mechanism 50 (see FIG. 10B). The book B pushed into the book storage chamber 53 is pressed from above and below by the pressing means 55, and the unpolished surface, for example, the small edge of the book B is polished by the first polishing mechanism 30A. Polishing is performed by being lifted and lowered by the lifting means 57 while being pressed against the band 37 (see FIG. 10C).

  During the polishing operation by the polishing mechanism 30, the transport mechanism 20 is retracted to the rear position, and the entrance / exit transport section 24 at the next stage is positioned in front of the first polishing mechanism 30A and stands by. At the same time, the entry / exit transport unit 24 at the last stage is positioned in front of the input mechanism 10, and the next book B of the next processing group to be polished is input and pushed onto the input / output transport unit 24.

  After the polishing, the book B in the book storage chamber 53 is returned onto the entrance / exit transport unit 24 of the second stage in the transport mechanism 20 at the retracted position by the release of the pressing means 55 and the operation of the book return mechanism 60. (See FIG. 10D). When returning, the transport mechanism 20 is positioned on the entrance / exit transport section 24 of the next stage because the transport mechanism 20 is in the retracted position, unlike the entrance / exit transport section 24 section of the previous stage when being pressed and moved to the polishing mechanism 30 side. The

  When the transport mechanism 20 moves forward again, during the forward transport operation, the book turning mechanism 70 lifts the book B slightly from the upper surface of the loading / unloading transport section 24 and at the same time by the upper and lower pressing plates 77 and 79. The book B is rotated at a predetermined angle in a predetermined direction as being sandwiched from above and below, and the top portion or the ground portion of the book B, which is an unpolished portion, is directed toward the polishing mechanism 30 (see FIG. 10E).

  When the transport mechanism 20 advances (see FIG. 10F) and the book B is transported to the front position of the second polishing mechanism 30B on the next stage side, the book movement support mechanism 40 similarly enters the polishing book lift mechanism 50. With the book B pushed in and pressed from above and below, the top portion or the ground portion is polished by the polishing band 37 of the polishing mechanism 30 together with the lifting operation of the polishing book lifting mechanism 50. After the polishing is completed, the book return mechanism 60 is actuated, and the book B is then placed on the third-stage entrance / exit transport unit 24 by the retracting operation of the transport mechanism 20. When the book is transported, the book turning mechanism 70 is rotated at a predetermined angle in a predetermined direction so that the unpolished part is directed to the third polishing mechanism 30C side of the next stage by the operation of the book turning mechanism 70, and the book which is the unpolished part The ground part or the top part of B is directed to the polishing mechanism 30 side.

  When the book B is transported to the front position of the third polishing mechanism 30C by the forward operation of the transport mechanism 20, the ground portion or the top portion is similarly polished by the book movement support mechanism 40 and the polishing book lifting mechanism 50, and after polishing, The book is returned to the transport mechanism 20 by the book return mechanism 60. At this time, the book B is placed on the entrance / exit transport unit 24 in the fourth stage (final stage) by the backward operation of the transport mechanism 20.

  When the transport mechanism 20 further moves forward, the fourth-stage entrance / exit transport unit 24 reaches the discharge table 93 of the discharge mechanism 90 and the rear position of the discharge conveyor 91, and the book movement support mechanism 40 and the discharge board 92 are moved forward and backward. Thus, the polished book B is pushed out onto the discharge conveyor 91 through the discharge table 93, and is moved out of the main frame 1 through the discharge port 5 by the operation of the discharge conveyor 91.

  That is, by the transport mechanism 20 that intermittently advances and retracts between the input port 2 in the input area where the unpolished book B is input for each processing group and the discharge port 5 part of the output area where the polished book B is discharged. In the process of transporting the book B of one processing group, the fore edge, top, and ground of the book B are each polished by the three adjacently arranged polishing mechanisms 30. At this time, when the transport mechanism 20 is in the retracted position, each of the books B having an unpolished portion is loaded on the entrance / exit transport unit 24 of the transport mechanism 20 and the book B being polished is returned. Yes, when the transport mechanism 20 transports the book B to the front side, the book B is turned during the transport, and the unpolished part is directed to the next polishing mechanism 30 side. When the transport mechanism 20 is in the forward position, the book B inserted or returned in the retracted position is transported to the front position of the next-stage polishing mechanism 30, where the book movement support mechanism 40, the polishing book lifting mechanism The book B to be polished by 50 is sent to the polishing mechanism 30 side of the next stage and polished by moving up and down. Further, the book B transported to the discharge mechanism 90 by being on the entrance / exit transport unit 24 at the foremost stage position is discharged through the discharge port 5 by the discharge mechanism 90. Such a series of processing of loading, conveying, polishing, and discharging of the book B is performed for each of the three polishing mechanisms 30 in the process of loading the unpolished book B and discharging the polished book B. It is performed by processing these simultaneously and in parallel while exchanging the books B to be sent.
