Description

Technical Field

[0001] The invention relates to the technical field of book block cover application, and in particular to a book block cover application device for a cover application machine. Background Art

[0002] In the field of modern printing and binding technology, with the demand of the market, the requirements for book printing and production are getting higher and higher, and many books need to be hardcovered. At present, there is no fully automatic book hardcover system in the field of printing and binding, and it can only be completed by manual or semi-automatic machines. The main disadvantage is that the book core and book cover produced are not accurately positioned, and the surrounding and edge positions are often skewed, resulting in an unsightly appearance of hardcover books. At the same time, it is difficult for manual operation to accurately grasp the size and uniformity of the glue application, so the refinement of the hardcover books produced is greatly weakened, which cannot meet the requirements of hardcover, and the scrap rate is high and is not accepted by customers. At the same time, manual or semi-automatic operation requires a lot of labor, and the efficiency of manual production is low, so it is only suitable for small batch order production, and it is often impossible to complete the slightly larger order requirements in time, so it has to increase the labor force, but a large amount of labor is bound to bring inconvenience to human management and increase production costs.

[0003] The main working process of the semi-automatic machine is to place the book case on top of the machine, so that the book case is in an open state, push the book core onto the book core conveyor plate between the two glue brushing devices, and the two glue brushing devices are close together. The book core conveyor plate rises with the book core under the action of the conveyor plate driving device, and the book core is lifted up and joined with the book case after being glued on both sides by the glue brushing device, completing the book production process. Then the book core conveyor plate moves the book to a flap, and the flap pushes the book down onto the conveyor belt for collection. The book with the book case is then subjected to the forming, flattening and grooving processes to complete the final processing. However, this book core cover device still has the following defects:

[0004] (1) The workbench of the cover loading machine is symmetrically provided with two chains along the conveying direction of the book block. The book block is placed between the two chains, and then the book block is moved to the cover loading position through the synchronous movement of the two chains. The positioning is poor and it is easy to cause indentation on the book block.

[0005] (2) The book core conveying plate is a vertically arranged push plate, which is inserted between two book pages of the book core, thereby driving the book core to move upward. This type of cover loading method is prone to the phenomenon that the book pages are bent by the push plate, causing damage to the book pages; during the process of lifting the book core, the bonding position of the book core is prone to tilt, resulting in inaccurate positioning of the book core and the book cover, reducing the qualified rate of the book.

DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0032] like Figure 1 As shown, the book block cover loading device for the cover loading machine provided in the embodiment of the present application includes a workbench 10, on which a pushing device, a book block conveying device 40 and a book cover conveying device are provided.

[0033] like Figure 2 As shown, the pushing device includes a pushing base 20 and two fire-wire knives 22 relatively arranged on the top of the pushing base 20, and the two fire-wire knives 22 are arranged in a horizontal direction. The relative here means that the top surfaces of the two fire-wire knives 22 are on the same horizontal plane, and the blades of the two fire-wire knives 22 are arranged in parallel. The pushing base 20 is provided with a first driving device for driving the two fire-wire knives 22 to move relative to each other, and a second driving device for driving the two fire-wire knives 22 to move synchronously in a vertical direction. The relative movement here means that the two fire-wire knives 22 are close to or away from each other, and the two fire-wire knives 22 move along a conveying direction perpendicular to the book core. Among them, the fire-wire knife 22 is a relatively common device in the field of book core upper shells, so it will not be described in detail.

[0034] Combination Figure 1 , Figure 3 and Figure 6As shown, the book block conveying device 40 includes a moving device, a first clamping device and a second clamping device. The moving device drives the first clamping device and the second clamping device to move synchronously along the conveying direction of the book block. The first clamping device is used to move the book block to the top of the two firing knives 22, and the second clamping device is used to move the book block above the firing knives 22 to the next working position. For the convenience of description, the initial position of the book block is referred to as the first working position, the position where the book block moves to the top of the firing knives 22 is referred to as the second working position, and the position where the book block moves to the next working position is referred to as the third working position. Specifically, the moving device drives the first clamping device to reciprocate between the first working position and the second working position, and the moving device drives the second clamping device to reciprocate between the second working position and the third working position. Among them, the second clamping device moves the book block with the upper shell in the second working position to the third working position.

[0035] The book cover mainly includes the front cover, back cover, spine and book groove. Among them, the front of the book is the cover of the book cover, the back of the book is the back cover of the book cover, and the spine, also called the back of the book, refers to the turning part of the book, which is used to connect the front cover and the back cover. Generally, the width of the back of the book is equivalent to the thickness of the book core, and the book and the front cover and the back cover are usually connected by the book groove to facilitate the bending of the book cover.

[0036] The book cover conveying device includes a third driving device for conveying the glued book cover to the top of the two firing knives 22. Preferably, the conveying direction of the book cover is the same as that of the book core, but the conveying of the book core and the book cover will not affect each other. The book core and the book cover are both on the same side of the firing knives 22, which reduces the volume of the entire device. The two book grooves of the book cover at the top of the firing knives 22 correspond to the positions of the blades of the two firing knives 22, respectively, so that the firing knives 22 can drive the book cover to move. The axis of the book cover at the top of the firing knives 22 coincides with the symmetry axis of the two firing knives 22, and the spine of the book cover corresponds to the position of the book core above the firing knives 22.

[0037] The present application moves the glue-brushed book cover to the top of the flash knife 22 through the third driving device, and then drives the book core to move above the book cover through the first clamping device. After the book core and book cover are moved into place, the first driving device drives the two flash knives 22 to drive the two sides of the book cover to move upward. At this time, the bottom of the book core is against the top of the spine, the book cover is bent from the book groove, and the flash knife 22 is supported on the side of the book cover. Specifically, the two flash knives 22 are against the book groove position of the book cover, and then the two flash knives 22 are driven to clamp by the second driving device, so that the flash knives 22 clamp the book groove, so that the book groove position of the book cover is bonded to the book core, and then the upper cover of the book core is completed.

[0038] This design method drives the book core to move through the first clamping device, which increases the accuracy of positioning and does not cause indentations on the book core. The book core shelling process is completed by pushing up and clamping the book shell, which avoids the occurrence of book core damage. The book core is positioned by the first clamping device during the shelling process, which avoids the book core from shaking during the shelling process, increases the accuracy of positioning, and improves the qualified rate of books.

[0039] like Figure 2 As shown, a placing platform 21 is provided on the top-pushing base 20, and the placing platform 21 is arranged in the horizontal direction, and the placing platform 21 and the bottom plate 201 of the top-pushing base 20 are arranged at intervals in the vertical direction. Two firing knife bases 221 for placing firing knifes 22 are symmetrically arranged on the top of the placing platform 21, and the blades of the two firing knifes 22 are arranged opposite to each other, and the two firing knife bases 221 are arranged at intervals along the conveying direction perpendicular to the book core, and the two firing knifes 22 are respectively arranged on the top of the two firing knife bases 221. The firing knife base 221 is slidably matched with the placing platform 21, so that the firing knife base 221 can move relative to the placing platform 21 along the conveying direction perpendicular to the book core, thereby driving the two firing knifes 22 to move. The side of the firing knife 22 close to the other firing knife 22 extends out of the firing knife base 221, that is, the blade of the firing knife 22 extends out of the side of the firing knife base 221, so that the two firing knifes 22 can clamp the book shell and complete the book core shelling step.

[0040] The first driving device includes a driving seat arranged on the side of the cross-line knife base 221 away from the blade of the cross-line knife 22, the driving seat is arranged on the top of the supporting platform 21, and the driving seat and the cross-line knife base 221 move synchronously relative to the supporting platform 21. The push base 20 is provided with a first screw 23 extending along the moving direction of the cross-line knife 22, and the driving seat is threadedly matched with the first screw 23. The driving seat is driven to move along the length direction of the first screw 23 through the rotation of the first screw 23, and then the cross-line knife 22 is driven to move along the conveying direction perpendicular to the book block through the cross-line knife base 221. Further optimized, at least two groups of the driving seat and the first screw 23 are arranged to ensure the stability of the movement of the cross-line knife base 221, so that the cross-line knife 22 moves along the conveying direction perpendicular to the book block.

[0041] Further optimized, the push base 20 is provided with a first motor assembly for driving the first screw 23 to rotate. In some embodiments, the first motor assembly is a first motor arranged at the end of the first screw 23, the first screw 23 is connected to the output shaft of the first motor, and the first screw 23 is driven to rotate by the rotation of the first motor. For the arrangement of multiple first screws 23, a first motor can be arranged at the end of each first screw 23, and the rotation speed of each first motor is the same. The synchronous rotation of each first motor drives the first screw 23 to rotate synchronously, thereby driving the firing knife base 221 to move smoothly.

[0042] In other embodiments, when two first screw rods 23 are provided, in order to reduce the driving equipment, the two first screw rods 23 can be driven to move by a transmission wheel group. Specifically, the first motor assembly includes a second motor 24, the output shaft of the second motor 24 is arranged along a direction perpendicular to the transmission direction of the book block, the end of the output shaft of the second motor 24 is provided with a first driving wheel, and the end of the first screw rod 23 is provided with a first driven wheel 26 meshing with the first driving wheel, and the two first driven wheels 26 are driven to rotate by the rotation of the first driving wheel, thereby driving the two first screw rods 23 to rotate, but the rotation directions of the two first screw rods 23 are opposite, so that the two first screw rods 23 can synchronously drive the fire line knife base 221 to move, the threads on the two first screw rods 23 are arranged in opposite directions.

[0043] Further optimized, in order to increase the distance between the two first screws 23 so that the force points of the firing knife base 221 are separated, a first transmission wheel 25 can be arranged between the first driving wheel and the first driven wheel 26. In addition, the rotation speed of the first screw 23 can be controlled by the diameter ratio between the first driving wheel, the first transmission wheel 25 and the first driven wheel 26, thereby increasing the convenience of use.

[0044] Further optimized, in order to reduce the space occupied by the entire device in the conveying direction perpendicular to the book core, the second motor 24 can be arranged along the conveying direction of the book core. Specifically, a first bevel gear is arranged on the output shaft of the second motor 24, and the push base 20 is arranged along the conveying direction perpendicular to the book core, and a steering rod is arranged at one end of the steering rod, and a second bevel gear meshing with the first bevel gear is arranged, and a second conveying wheel is arranged at the other end of the steering rod, and the second conveying wheel is meshed with both the first conveying wheels 25. The steering rod can be driven to rotate by the rotation of the second motor 24, wherein the first bevel gear and the second bevel gear are used to change the rotation direction.

[0045] It can be seen that the arrangement of the first motor assembly is not limited, as long as the rotation of the first motor assembly can drive the first screw 23 to rotate, thereby driving the crosshair knife base 221 to move along a conveying direction perpendicular to the book block.

[0046] like Figure 2 As shown, the second driving device of the present application includes a plurality of first telescopic mechanisms 30 arranged below the placing platform 21, and the placing platform 21 and the pushing base 20 slide and cooperate in the vertical direction. The placing platform 21 is driven to move in the vertical direction by the telescopic movement of the first telescopic mechanism 30, thereby driving the two fire line knives 22 to move in the vertical direction. The first telescopic mechanism 30 is arranged between the placing platform 21 and the bottom plate 201 of the pushing base 20, and the first telescopic mechanism 30 can be an electric push rod, a cylinder or a hydraulic cylinder, etc. As long as it can move in the vertical direction and realize the self-locking function.

[0047] For further optimization, the push base 20 is provided with a plurality of pillars 27 in the vertical direction, and the supporting platform 21 is provided with a sliding block 28 that slidably cooperates with the pillars 27. Specifically, a sliding hole is provided in the middle of the sliding block 28 in the vertical direction, and the pillar 27 slides in the sliding hole.

[0048] A support plate 29 for supporting the spine of the book case is provided between the two firing knives 22. The top of the support plate 29 is flush with the tops of the two firing knives 22. The push base 20 is provided with a bracket 291 in the vertical direction. The bracket 291 is slidably matched with the placing platform 21, and the support plate 29 is arranged on the top of the bracket 291. This design enables the support plate 29 and the two firing knives 22 to move relative to each other in the vertical direction. When the two firing knives 22 drive the two sides of the book case to move vertically upward, the book case is between the support plate 29 and the book core. The support plate 29 provides reverse support force for the book case, increases the accuracy of the bonding between the book case and the book core, and ensures the yield rate.

[0049] Combination Figure 3 and Figure 6 As shown, the first clamping device and the second clamping device of the present application both include two clamping plates 41 arranged opposite to each other, the clamping plates 41 are arranged on a clamping plate base 50, and the clamping plates 41 are arranged on one side of the clamping plate base 50 facing the other clamping plate base 50, so that the two clamping plates 41 are opposite to each other and are used to clamp the book block. The clamping plate base 50 is provided with a fourth driving device for driving the clamping plates 41 to move along a direction perpendicular to the conveying direction of the book block, and a fifth driving device for driving the clamping plates 41 to move in a vertical direction. The movement here refers to the movement of the clamping plates 41 relative to the clamping plate base 50 in the vertical direction and in the conveying direction perpendicular to the book block.

[0050] Combination Figure 1 and Figure 3 As shown, the moving device includes two sliders 60 extending along the conveying direction of the book block, and the slider 60 is provided with a slideway 61 along its length direction. The clamping plate base 50 is provided with a slide plate that slidably cooperates with the slideway 61, that is, the slide plate and the clamping plate base 50 are wrapped around the outer periphery of the slider 60. A second screw is provided inside the slideway 61 for rotation, and the slide plate is threadedly engaged with the second screw. A second motor assembly for driving the second screw to rotate is provided at the end of the second screw. The second motor assembly drives the second screw to rotate, and then the slide plate drives the clamping plate base 50 to move along the length direction of the second screw.

[0051] In some embodiments, the second motor assembly includes two third motors respectively arranged at the ends of the two second screw rods. The two second screw rods are driven to rotate synchronously through the synchronous rotation of the third motors, and the structure is simple.

[0052] In other embodiments, the second motor assembly includes a fourth motor 62, and the output shaft of the fourth motor 62 is extended and arranged perpendicular to the conveying direction of the book core. The outer periphery and end of the output shaft of the fourth motor 62 are provided with a third bevel gear, and the ends of the two second screws are provided with a fourth bevel gear, the two fourth bevel gears and the two third bevel gears are positioned relative to each other, and the two fourth bevel gears are respectively engaged with the two third bevel paper wheels.

This design method can reduce the size of the device in the book core conveying direction, reduce the driving device, and reduce the cost.

[0053] like Figure 6 As shown, the top of the clamping plate base 50 is slidably matched with the mounting plate 51 along the moving direction perpendicular to the book block, and the clamping plate 41 is vertically arranged at the end of the mounting plate 51.

In order to reduce the volume of a single first clamping device and a second clamping device, the fifth motor 54 may be disposed on a side of the vertical mounting plate 53 close to the baffle. Specifically, the output shaft of the fifth motor 54 extends out of the vertical mounting plate 53, and a driving pulley 541 is disposed at the protruding end of the output shaft of the fifth motor 54, the end of the third screw 52 also extends out of the vertical mounting plate 53, a driven pulley 542 is disposed at the protruding end of the third screw 52, ​​and a belt 543 is disposed on the outer periphery of the driving pulley 541 and the driven pulley 542, and the third screw 52 is driven to rotate by the rotation of the fifth motor 54. Further optimized, the diameter of the driving pulley 541 is smaller than the diameter of the driven pulley 542, so that the rotation speed of the third screw 52 is lower than the rotation speed of the output shaft of the fifth motor 54, which is easy to adjust. Among them, the driving pulley 541 and the driven pulley 542 can be replaced by gears, and the belt 543 can be replaced by a chain.

[0056] In other embodiments, a third telescopic mechanism may be provided on the vertical mounting plate 53, wherein the third telescopic mechanism may be an electric push rod, a cylinder or a hydraulic cylinder.

[0059] In other embodiments, the second telescopic mechanism 56 includes a sixth motor arranged in the vertical direction, and a fourth screw is provided at the end of the sixth motor. The fourth screw is threadedly engaged with the connecting plate, and the rotation of the fourth screw drives the connecting plate to move along the length direction of the fourth screw, thereby driving the clamping plate 41 to move in the vertical direction.

[0060] like Figure 3 As shown, in order to facilitate the clamping of the book block by the clamping plate 41 and to prevent the clamping plate 41 from affecting the movement of the book block, a clamping block 411 can be provided at the bottom of the side of each clamping plate 41, and a clamping device is provided on one of the clamping blocks 411 of the two clamping plates 41 arranged opposite to each other, and the clamping device includes a guide column extending along the moving direction of the clamping plate 41, and the clamping block 411 is slidably matched with the guide column, and a spring is provided on the outer periphery of the part of the guide column between the clamping plate 41 and the clamping block 411. Among them, the clamping block 411 has a certain thickness, and the two ends of the spring are respectively connected to the inside of the clamping plate 41 and the clamping block 411. In the non-clamping state, the spring remains in its original state. When the book block is clamped, the spring is compressed, and the guide column slides inside the clamping block 411, but does not extend out of the end of the clamping block 411, so as to prevent the guide column from contacting the book block. When in use, the book core is clamped by two clamping blocks 411, reducing the volume of the contact surface between the clamping plate 41 and the book core, facilitating the installation of the guide device, and one of the clamping blocks 411 can be extended and retracted along a direction perpendicular to the conveying direction of the book core, so that the clamping block 411 is in elastic contact with the book core, avoiding the clamping block 411 from causing indentations on the book core.

[0061] like Figure 1 As shown, the guide device is two limit rods 11 extending along the conveying direction of the book core, the distance between the two limit rods 11 is enough for the book core to pass through, and the two clamps 41 are respectively arranged on the outside of the two limit rods 11, and the two limit rods 11 are both arranged above the clamping block 411, and the two limit rods 11 are arranged opposite to each other in the horizontal direction. The two limit rods 11 guide the movement of the book core and prevent the pages of the book core from spreading. Among them, the thickness of the clamping block 411 should be greater than the thickness of the limit rod 11 in the conveying direction perpendicular to the book core, so that the clamping block 411 can be clamped on the outside of the book core.

[0062] like Figure 4As shown, a book core positioning device is provided on the workbench 10 of the present application. The book core positioning device includes a conveyor belt 70 extending along the conveying direction of the book core. A limit plate 71 is provided at one end of the conveyor belt 70 away from the pushing device. The conveyor belt 70 drives the book core at the top thereof to move toward the limit plate 71, so that the book core contacts the side of the limit plate 71. At this time, the position of the book core is the first working position. The first clamping device moves the book core at the top of the conveyor belt 70, i.e., the first working position, to above the two firing knives 22. By providing a book core positioning device, all book cores placed on the conveyor belt 70 are moved to the first working position, and then the book core at the first working position is moved to the second working position by the first clamping device, so that the position of the book core at the second working position is accurate, which is convenient for the upper shell of the book core and improves the qualified rate of the product.

[0063] Further optimization, such as Figure 5 As shown, two guide plates 72 are provided above the conveyor belt 70 along the length direction of the conveyor belt 70, the bottom of the guide plate 72 is spaced from the top of the conveyor belt 70, and the distance between the bottom of the guide plate 72 and the top of the conveyor belt 70 is less than the height of the book block, the two guide plates 72 are spaced, and the book block is arranged between the two guide plates 72. Two limit rods 11 are respectively connected to the two guide plates 72 to guide the movement of the book block.

[0064] The book case conveying device includes a book case conveying plate and two pushers. The book case conveying plate is arranged along the conveying direction of the book block. The book case conveying plate is connected to the end of the line knife 22. Two pusher slideways 61 arranged along the conveying direction of the book block are arranged on the book case conveying plate. The two pushers move on the pusher slideways 61, and the tops of the pushers extend out of the pusher slideways 61. The book case conveying plate is arranged below the conveyor belt 70. The distance between the book case conveying plate and the conveyor belt 70 is greater than the thickness of the book case, which is convenient for the book case to pass through and avoids mutual influence between the book block conveying and the book case conveying. In order to facilitate the book case to move to the top of the line knife 22, a slope is arranged at the end of the line knife 22.

[0065] The book block conveying direction of the present application indicates the designed conveying direction of the book block, and perpendicular to the conveying direction of the book block means that the direction is perpendicular to the conveying direction of the book block on the horizontal plane.

[0066] Here’s how this application works:

[0067] When the book case moves to a certain position on the book case conveying plate, the glue is applied, and then the book case is pushed to the top of the two firing knives 22 by the pusher. At the same time, the book block is placed between the two guide plates 72, and the book block falls on the conveyor belt 70, which drives the book block to move until the book block contacts the side of the limit plate 71, and the conveyor belt 70 stops rotating. At this time, the book block is in the first working position, the first clamping device is in the first working position, and the second clamping device is in the second working position.

[0068] The two clamping plates 41 on the first clamping device are located on both sides of the book block. The two clamping plates 41 move toward each other and clamp the book block through the two clamping blocks 411. At this time, the two clamping plates 41 drive the book block to move upward, so that the book block is separated from the conveyor belt 70, and the two clamping plates 41 drive the book block to move to the second working position. At the same time, the second clamping device moves from the second working position to the third working position. When the first clamping device moves to the second working position, the two clamping plates 41 drive the book block to move downward, so that the book block contacts the spine of the book case, and the position of the clamping plates 41 remains unchanged.

[0069] When the book core contacts the book case, the two firing knives 22 move vertically upward, thereby driving the two sides of the book case to move upward until the set position. At this time, the firing knives 22 are against the outer side of the book groove of the book case, and the two firing knives 22 move toward each other, thereby clamping the book case and the book core, completing the upper shell of the book core, and the firing knives 22 are reset.

[0070] When the book core is finished with the upper shell, the two clamping plates 41 of the first clamping device move in opposite directions, the two clamping blocks 411 loosen the book core, and the position of the book core is limited by the support plate 29 and the two limit rods 11. The two first clamping devices return to the first working position to prepare for the next movement of the book core. The second clamping device returns from the third working position to the second working position, and the two clamping plates 41 on the second clamping device move toward each other, so that the clamping blocks 411 clamp the book core after the upper shell, and the two clamping plates 41 drive the book core to move upward, so that the book core is separated from the support plate 29, and the second clamping device drives the book core after the upper shell to move to the third working position. A guide curved plate is arranged below the third working position, the guide curved plate is arranged obliquely and bent toward one side of the book, and two baffles are arranged in parallel above the guide curved plate, and the width of the two baffles is greater than the width of the spine of the book shell, so that the book can pass between the two baffles. After the second clamping device releases the book core, the two sides of the book case contact the baffle rods, and the two baffle rods respectively drive the two sides of the book case to move toward the book core, so that the book case fits the side of the book core. After the book falls and contacts the guide curved plate, the book tilts toward the guide curved plate, and the book slides downward on the guide curved plate, and then proceeds to the next step of flattening and grooving process.

[0071] The first clamping device and the second clamping device move synchronously, that is, when the first clamping device clamps the book core at the first working position, the second clamping device simultaneously clamps the book core behind the upper shell at the second working position. The moving device drives the first clamping device and the second clamping device to move synchronously, that is, the first clamping device moves the book core at the first working position to the second working position, and the second clamping device moves the book core at the second working position to the third working position. This design can effectively increase work efficiency and reduce equipment costs.
