Description

Technical Field

[0001] This invention relates to the field of book packing technology, and in particular to a book packing machine bottom support mechanism and its usage method, and a book packing machine. Background Technology

[0002] With increasingly fierce competition in the book printing market and rising labor costs, the requirements for book binding workshops that need to pack and transport books are becoming more stringent. Currently, the main process for book packing in China is as follows: Books are manually stacked neatly, the stack size depending on the box dimensions. Empty cartons are then opened and placed on top of the stacks, ensuring the inner and outer flaps of the cartons are flush with the bottom of the stacks. The entire stack is then pushed into the case packing machine, which automatically performs the packing operations (sealing the bottom and top flaps, corner folding, and automatic strapping). In practice, the main technical challenges lie in reliably and automatically folding the inner and outer flaps of the cartons after they are pushed into the case packing machine, as well as adjusting for changes in box dimensions. Therefore, there is still room for improvement in the structural design of this part. Although similar case packing machines exist abroad, they are more limited in variety and have fixed specifications, making them unsuitable for the domestic market. In contrast, domestic products have a wider range of specifications, resulting in numerous and frequently changing packing requirements for different sizes and types of books. This invention is proposed based on the above research background, and aims to provide a book packing machine bottom support mechanism to meet the actual needs of book printing and binding. Summary of the Invention

[0003] In view of the above-mentioned defects of existing book packing machines, the purpose of this invention is to provide a book packing machine bottom support mechanism and its usage method, and a book packing machine with reasonable structural design and convenient use. It can be adapted to bottom support mechanisms of packing machines of different specifications and lengths. It can not only flexibly adjust the length of the box, but also ensure the stability of the stack of books during the packing process and prevent damage to the cover appearance of the books.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] A book packing machine bottom support mechanism includes a folding slide 1, a carton folding mechanism 2, a carton sealing mechanism for both sides of the carton end caps 3, and a carton moving push rod mechanism 5 for driving the carton 4 to move from right to left. The folding slide includes a first linear drive mechanism and a first guide rail 6. The carton folding mechanism includes a first folding assembly 7 for folding the left inner flap L of the carton and a second folding assembly 8 for folding the right inner flap R of the carton. The first and second folding assemblies are located on the same straight line, and the second folding assembly reciprocates linearly on the first guide rail via the first linear drive mechanism, moving away from or closer to the first folding assembly. Both the first and second folding assemblies include several parallel and spaced components located on the same base. The first folding assembly also includes a baffle mechanism 10 rotatably mounted on the vertical plate and a baffle cylinder 11 for driving the baffle mechanism to rotate. When the baffle cylinder drives the baffle mechanism to rotate to a vertical position, it can block the carton from moving to the left when folding the inner flap on the left side of the carton. When the baffle cylinder drives the baffle mechanism to rotate to a horizontal position and is located below the extension plate, the carton can continue to move to the left under the drive of the carton moving push rod mechanism. An extension plate 12 is also fixedly connected to the top left side of the first folding assembly, and an auxiliary plate 13 is also provided below the extension plate. The extension plate can slide back and forth relative to the auxiliary plate. The end cap mechanism on both sides of the carton is located at the bottom of the auxiliary plate for folding the outer flaps F and B on the front and rear sides of the carton.

[0006] As a further optimization of the above solution, the first linear drive mechanism includes a servo motor, a lead screw that drives the servo motor, and a lead screw nut that drives the lead screw. The lead screw nut is fixedly connected to the base of the folding carton mechanism. The sealing carton end cap mechanism includes inclined extension rods symmetrically arranged on the front and rear sides of the extension plate. The left end of the inclined extension rod is higher than the right end. The left end of the inclined extension rod is fixedly arranged below the auxiliary plate. The horizontal distance between the left ends of the front and rear inclined extension rods is smaller than the horizontal distance between the right ends, and the distance between the right ends is greater than the distance between the outer flaps on the front and rear sides of the carton.

[0007] As a further optimization of the above solution, the second folding assembly also includes a top folding mechanism on the vertical plate at the middle position. The top folding mechanism includes a folding plate 14 hinged to the vertical plate at the middle position, and a telescopic cylinder 15 with one end hinged to the bottom of the folding plate and the other end hinged to the vertical plate at the middle position. The telescopic cylinder drives the folding plate to reciprocate to fold the inner flap on the right side of the carton.

[0008] As a further optimization of the above solution, the bottom support mechanism of the book packing machine also includes a carton length adjustment mechanism 16. The carton length adjustment mechanism includes a second guide rail 17 disposed below the first folding assembly and a second linear drive mechanism for driving the first folding assembly to slide linearly back and forth on the second guide rail. The first linear drive mechanism includes a servo motor, a lead screw that drives the servo motor, and a lead screw nut that drives the lead screw. The lead screw nut is fixedly connected to the base of the second folding assembly.

[0009] As a further optimization of the above scheme, the folding slide, the first guide rail and the second folding assembly are all located on aluminum plate 18; the second guide rail and the first folding assembly are both located on aluminum plate 19; the second linear drive mechanism and the sealing box end cap mechanism are both located on aluminum plate 20.

[0010] As a further optimization of the above solution, each vertical plate of the first folding assembly and the second folding assembly is also provided with a pulley 21 on its top to prevent scratching the book.

[0011] As a further optimization of the above solution, the carton moving push rod mechanism includes: a push rod 22, a ring drive chain 23, a drive servo motor 24, a ring transmission chain 25, and a transmission shaft 26. The two ends of the push rod are fixed on the ring drive chain. A drive sprocket is provided on the output shaft of the drive servo motor. The output shaft is drivenly connected to the transmission shaft. A transmission sprocket is provided on the transmission shaft. The ring transmission chain is wound around the drive sprocket and the transmission sprocket. The carton is placed on the push rod. The ring drive chain is moved by the drive servo motor, which in turn moves the carton on the push rod from right to left.

[0012] The method of using the book packing machine bottom support mechanism of the present invention includes the following steps:

[0013] 1) When the carton and the stack of books inside the carton enter the carton packing machine, the carton and books move from right to left under the push of the push rod 14 of the carton moving push rod mechanism. The stack of books inside the carton moves to the pulley of the mechanism, which carries the contents of the carton while ensuring that the bottom surface of the books is not damaged.

[0014] 2) Then, the folding plate is driven by the telescopic cylinder to rotate from the initial state to the horizontal state, and the inner flap on the right side of the carton is lifted and folded. After folding, the folding plate rotates to the initial state under the drive of the telescopic cylinder. At the same time, the first linear drive mechanism drives the carton and the books inside to move forward. The baffle mechanism is retracted under the drive of the baffle cylinder. The carton and the books continue to move forward, and the inner flap on the left side of the bottom of the carton is folded over. As the whole mechanism moves, the inner flap on the rear side of the carton is completely folded over.

[0015] 3) The carton, along with the books it carries, continues to move forward and onto the extension plate. The outer flaps on both sides of the carton begin to contact the fixed end cap mechanisms on both sides of the carton, thus folding the outer flaps on the front and back sides of the carton until the bottom of the carton is completely folded. The carton then enters the exit and enters the operation steps of the folding and sealing machine.

[0016] As a further optimization of the above scheme, the folding of the front and rear outer flaps of the carton in step 3) includes: the carton moves to the left under the push of the push rod, and the front ends of the outer flaps on both sides of the carton enter the interior between the front and rear inclined extension rods in the end cap mechanism of the carton. As it moves to the left, they gradually close together. The carton and the books inside are under the extension plate and the auxiliary plate. The extension plate also moves to the left synchronously under the drive of the push rod. Since the horizontal distance between the left ends of the front and rear inclined extension rods is smaller than the horizontal distance between the right ends, and the distance between the right ends is greater than the distance between the front and rear outer flaps of the carton, this allows the carton to fold the front and rear outer flaps inward during the process of moving to the left. The method of use also includes step 4): when the carton specifications change and the length of the bottom support mechanism of the book packing machine needs to be changed, the first folding mechanism can move back and forth under the drive of the second linear drive mechanism to adapt to different carton length requirements.

[0017] A book packing machine includes the aforementioned book packing machine bottom support mechanism and a carton pressing mechanism; wherein the carton pressing mechanism includes a pressing plate 27, a pressing cylinder 28, a transmission screw 29, a lifting motor 30, and a pressing cylinder mounting base 31. The pressing plate and the pressing cylinder are connected, and the lifting motor is driven by the transmission screw. The pressing cylinder is fixedly mounted on the pressing cylinder mounting base, and the pressing cylinder mounting base is connected to the transmission screw. The lifting motor drives the transmission screw to move, thereby driving the pressing cylinder mounting base to perform a linear lifting motion.

[0018] The beneficial effects of using the book packing machine bottom support mechanism of the present invention are as follows: it can be adapted to packing machine bottom support mechanisms of different specifications and lengths, not only can the length of the box be flexibly adjusted, but it can also ensure the stability of the stack of books during the packing process and prevent damage to the cover appearance of the books.

Specifically, the baffle mechanism rotates via a rotating shaft. The piston rod of the baffle cylinder is hinged to the bottom of the baffle mechanism in the vertical plate of the first folding assembly.

In this embodiment, the baffle mechanism is a strip plate, and the top of the strip plate can also be provided with an arc transition. When the baffle cylinder drives the baffle mechanism to rotate to the vertical state, it can block the carton from moving to the left when folding the inner flap on the left side of the carton. When the baffle cylinder drives the baffle mechanism to rotate to the horizontal state and is located below the extension plate, the carton can continue to move to the left under the drive of the carton moving push rod mechanism. An extension plate 12 is also fixedly connected to the top left side of the first folding assembly. An auxiliary plate 13 is also provided below the extension plate, and the extension plate can slide back and forth relative to the auxiliary plate. The sealing end cap mechanism on both sides of the carton is provided at the bottom of the auxiliary plate for folding the outer flaps F and B on the front and rear sides of the carton. The first linear drive mechanism includes a servo motor, a lead screw that drives the servo motor, and a lead screw nut that drives the lead screw. The lead screw nut is fixedly connected to the base of the carton folding mechanism. The carton sealing end cap mechanism includes inclined extending rods symmetrically arranged on the front and rear sides of the extension plate. The left end of the inclined extending rod is higher than the right end. The left end of the inclined extending rod is fixedly arranged below the auxiliary plate. The horizontal distance between the left ends of the front and rear inclined extending rods is smaller than the horizontal distance between the right ends, and the distance between the right ends is greater than the distance between the outer flaps on the front and rear sides of the carton. The second folding assembly also includes a top folding mechanism on the vertical plate at the middle position. The top folding mechanism includes a folding plate 14 hinged to the vertical plate at the middle position, and a telescopic cylinder 15 with one end hinged to the bottom of the folding plate and the other end hinged to the vertical plate at the middle position. The telescopic cylinder drives the folding plate to reciprocate to fold the inner flap on the right side of the carton.The book boxing machine's bottom support mechanism also includes a carton length adjustment mechanism 16. This mechanism includes a second guide rail 17 located below the first folding assembly and a second linear drive mechanism for driving the first folding assembly to slide linearly back and forth on the second guide rail. The first linear drive mechanism includes a servo motor, a lead screw that drives the servo motor, and a lead screw nut that drives the lead screw. The lead screw nut is fixedly connected to the base of the second folding assembly.

The carton moving push rod mechanism includes a push rod 22, a ring drive chain 23, a drive servo motor 24, a ring transmission chain 25, and a transmission shaft 26. The two ends of the push rod are fixed on the ring drive chain. A drive sprocket is provided on the output shaft of the drive servo motor. The output shaft is driven and connected to the transmission shaft. A transmission sprocket is provided on the transmission shaft. The ring transmission chain is wound around the drive sprocket and the transmission sprocket. The carton is placed on the push rod. The ring drive chain is moved by the drive servo motor, which in turn moves the carton on the push rod from right to left.

[0028] The method of using the book packing machine bottom support mechanism described above includes the following steps:

[0029] 1) When the carton and the stack of books inside the carton enter the carton packing machine, the carton and books move from right to left under the push of the push rod 14 of the carton moving push rod mechanism. The stack of books inside the carton moves to the pulley of the mechanism, which carries the contents of the carton while ensuring that the bottom surface of the books is not damaged.

[0030] 2) Then, the folding plate is driven by the telescopic cylinder to rotate from the initial state to the horizontal state, and the inner flap on the right side of the carton is lifted and folded. After folding, the folding plate rotates to the initial state under the drive of the telescopic cylinder. At the same time, the first linear drive mechanism drives the carton and the books inside to move forward. The baffle mechanism is retracted under the drive of the baffle cylinder. The carton and the books continue to move forward, and the inner flap on the left side of the bottom of the carton is folded over. As the whole mechanism moves, the inner flap on the rear side of the carton is completely folded over.

[0031] 3) The carton, along with the books it carries, continues to move forward and onto the extension plate. The outer flaps on both sides of the carton begin to contact the fixed end cap mechanisms on both sides of the carton, thus folding the outer flaps on the front and back sides of the carton until the bottom of the carton is completely folded. The carton then enters the exit and enters the operation steps of the folding and sealing machine.

[0032] The folding of the front and rear outer flaps of the carton in step 3) includes: the carton moves to the left under the push of the push rod, and the front ends of the outer flaps on both sides of the carton enter the interior between the front and rear inclined extension rods in the end cover mechanism of the carton. As it moves to the left, they gradually close together. The carton and the books inside are under the extension plate and the auxiliary plate. The extension plate also moves to the left synchronously under the drive of the push rod. Since the horizontal distance between the left ends of the front and rear inclined extension rods is smaller than the horizontal distance between the right ends, and the distance between the right ends is greater than the distance between the front and rear outer flaps of the carton, the carton folds the front and rear outer flaps inward during the process of moving to the left. The method of use also includes step 4): when the carton size changes and the length of the bottom support mechanism of the book packing machine needs to be changed, the first folding mechanism can move back and forth under the drive of the second linear drive mechanism to adapt to different carton length requirements.

[0033] The book packing machine of the present invention includes the aforementioned book packing machine bottom support mechanism, and further includes a carton pressing mechanism; wherein, the carton pressing mechanism includes a pressing plate 27, a pressing cylinder 28, a transmission screw 29, a lifting motor 30, and a pressing cylinder mounting base 31. The pressing plate and the pressing cylinder are connected, and the lifting motor is driven by the transmission screw. The pressing cylinder is fixedly mounted on the pressing cylinder mounting base, and the pressing cylinder mounting base is connected to the transmission screw. The lifting motor drives the transmission screw to move, thereby driving the pressing cylinder mounting base to perform a linear lifting motion.
