DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Reference Figure 1-15 An embodiment of the present invention provides a wrapping machine, including a main body 1, on which a bottom plate lifting mechanism, a paper pressing plate 2 and a paper picking mechanism are arranged, the bottom plate lifting mechanism is used to place a tray and raise the height of the tray; the paper pressing plate 2 is movably arranged on the main body 1, and the paper pressing plate 2 has a first position that contacts the top of the packaging paper and a second position that moves away from the top of the packaging paper; when the paper pressing plate 2 is in the second position, the paper picking mechanism takes out the topmost layer of packaging paper, and when the paper pressing plate 2 is reset to the first position, the paper picking mechanism places the packaging paper on the paper pressing plate 2.

[0041] Specifically, the wrapping machine generally includes a paper feeding module, a material feeding module (for arranging books to be packaged), a packaging module and a labeling circulation module; in the paper feeding module, the packaging paper is unfolded and stacked on a pallet, and the paper feeding module needs to take out the top layer of packaging paper on the pallet to a designated position, so that the clamping structure in the packaging module can directly clamp it to the packaging module. In the process of clamping the packaging paper, the unfolded packaging paper can be folded by the folding mechanism in the wrapping machine to form a carton and package the sorted books, and then the carton is moved to the labeling circulation module for labeling and transfer operations; the above are all existing technologies and will not be repeated here. The main body 1 in the embodiment of the present invention is a part of the paper feeding module, which is constructed as an outer cover shell structure. The main body 1 has a certain space inside and an opening on one side. The innovation of the embodiment of the present invention is that a bottom plate lifting mechanism, a paper pressing board 2 and a paper picking mechanism are arranged in the main body 1. The bottom plate lifting mechanism can use a lifting structure in the prior art (such as an electric slide rail) to raise the height of the tray. The paper pressing board 2 is a plate structure, and its bottom is constructed as a plane to contact the uppermost layer of packaging paper on the tray. The main body 1 can be provided with a mechanical arm in the prior art to drive the paper pressing board 2 to move in the main body 1. The paper picking mechanism can use a combination of a mechanical arm and a vacuum suction cup 3 in the prior art to move the vacuum suction cup 3 to the uppermost layer of packaging paper through the mechanical arm, so that after the vacuum suction cup 3 absorbs the packaging paper, the packaging paper is moved by the mechanical arm, and then the packaging paper is placed on the paper pressing board 2 in the first position, such as Figure 2 As shown (during the process, the paperboard 2 moves to the second position to avoid, as shown in Figure 3 As shown), the uppermost layer of wrapping paper on the pallet can be separated by the paper pressing plate 2; the advantage is that the paper pressing plate 2 can squeeze the wrapping paper stacked on the pallet, so as to limit the height of the wrapping paper on the pallet; when in use, the paper picking mechanism and the paper pressing plate 2 cooperate to move the uppermost layer of wrapping paper from the bottom of the paper pressing plate 2 to the top of the paper pressing plate 2, so as to separate the uppermost layer of wrapping paper by the paper pressing plate 2, so as to facilitate the gripper structure in the packaging module to take it; after the uppermost layer of wrapping paper moves to the top of the paper pressing plate 2, the height of the pallet can be raised by the bottom plate lifting mechanism, so that the wrapping paper on the pallet fits to the bottom of the paper pressing plate 2, in preparation for taking the wrapping paper next time, so as to adapt to the continuous operation of the wrapping machine.

[0042] A wrapping machine provided by an embodiment of the present invention can lift the height of a tray and the wrapping paper on the tray by setting a bottom plate lifting mechanism. When the tray is lifted to a certain height, the uppermost layer of wrapping paper will contact the bottom of a paper pressing board 2, thereby limiting the position of the wrapping paper on the tray. When the wrapping machine needs to take paper, the paper pressing board 2 moves to the second position, and at the same time, the paper taking mechanism takes out the uppermost layer of wrapping paper, and then the paper pressing board 2 is reset to the first position, and the paper taking mechanism places the wrapping paper on the paper pressing board 2, thereby placing the uppermost layer of wrapping paper at a designated position (that is, on the paper pressing board 2 in the first position) to wait for other structures of the wrapping machine to take it for wrapping books.

[0043] In another embodiment provided by the present invention, further, the two ends of the paperboard 2 are constructed in an arc shape. Specifically, a pressure sensor is provided at the bottom of the paperboard 2. When the bottom plate lifting mechanism lifts the height of the tray and the packaging paper, the top layer of packaging paper on the tray will press the pressure sensor. When the pressure sensor detects that the pressure reaches the set value, the electric signal fed back by the pressure sensor can control the bottom plate lifting mechanism to stop running. At this time, the pressure on the packaging paper on the tray is relatively appropriate, so that the height of the packaging paper on the tray is limited by the bottom of the paperboard 2, and the packaging paper on the tray is prevented from moving upward under the action of tension as much as possible; the arc structures at both ends of the paperboard 2 face the top, that is, the arc structures will not affect the restriction of the paperboard 2 on the packaging paper on the tray. When the top layer of packaging paper is taken out to the top of the paperboard 2 by the paper taking mechanism, the taken out packaging paper can be supported by the arc structure, and the taken out packaging paper and the packaging paper on the tray can be separated by a certain height by the arc structure, thereby increasing the operating space of the clamping structure in the packaging module, and facilitating the packaging module to take the packaging paper at a designated position.

[0044] Furthermore, the base plate lifting mechanism includes a support plate 4 slidably arranged in the main body 1, two transmission disks 5 are rotatably connected in the main body 1, a transmission belt 6 is arranged between the two transmission disks 5, and the support plate 4 is fixed on the transmission belt 6. Specifically, two guide columns 7 are vertically fixed in the main body 1, and the pallet 4 is slidably connected to the two guide columns 7. The pallet 4 is adapted to the space in the main body 1, and the pallet can be placed on the pallet 4 to adjust the height of the pallet when the pallet 4 is lifted or lowered along the guide columns 7, thereby stably lifting the height of the pallet; a limit plate 8 can be slidably set on the pallet 4 to limit the position of the pallet, which is not repeated here; the transmission belt 6 is mounted on the two transmission disks 5 to drive the two transmission disks 5 to rotate synchronously and in the same direction through the transmission belt 6 (the transmission belt 6 and the transmission disk 5 can also be replaced by a gear and chain structure), the pallet 4 is fixed on the transmission belt 6 (on the vertical part between the two transmission disks 5), and during the rotation of the two transmission disks 5 (the transmission disk 5 can be driven by the motor structure in the prior art), the transmission belt 6 is transmitted synchronously, and then the transmission belt 6 drives the pallet 4 to be lifted or lowered along the guide columns 7, thereby increasing the height of the pallet and the packaging paper thereon.

[0045] Furthermore, a first gear 9 is coaxially fixed on the transmission disc 5, a second gear 10 meshing with the first gear 9 is rotatably connected on the main body 1, and a third gear 11 is coaxially fixed on the second gear 10. Specifically, the first gear 9 is fixed on a transmission disc 5 located above, and since the first gear 9 is meshing with the second gear 10, and the second gear 10 is coaxially fixed with the third gear 11, when the third gear 11 rotates, it can drive the transmission disc 5 located above to rotate through the first gear 9 and the second gear 10 (an additional motor structure can be provided on the main body 1 to drive the third gear 11 to rotate). The diameter of the second gear 10 is smaller than the diameter of the first gear 9, so that the transmission ratio of the third gear 11 in the process of driving the first gear 9 to rotate is greater than 1, that is, the third gear 11 rotates several times to drive the first gear 9 to rotate one circle; the advantage is that, in this embodiment, the transmission disc 5 located above can not only be directly driven by the motor structure to rotate, but also driven by the third gear 11 to reduce the speed of rotation. During the process of the bottom plate lifting mechanism driving the pallet to rise until the pressure sensor reaches the set pressure value and during the process of the bottom plate lifting mechanism driving the pallet to descend, the transmission plate 5 located above can be directly driven by the motor structure to achieve the effect of quickly adjusting the position of the pallet, thereby improving the efficiency of the wrapping machine in replacing the pallet; when the cardboard press 2 and the paper picking mechanism are running, the top layer of packaging paper on the pallet moves to the top of the cardboard press 2. During the process, the bottom plate lifting mechanism is slowly lifted to continuously push the packaging paper on the pallet against the bottom of the cardboard press 2 (the height to which the bottom plate lifting mechanism drives the pallet to rise is approximately equal to the thickness of one packaging paper). At this time, the transmission plate 5 located above can be driven by the third gear 11 to rotate at a reduced speed, thereby improving the transmission accuracy while slowing down the rising speed of the pallet, and trying to avoid the pressure detected by the pressure sensor being too large or too small.

[0046] As an alternative to the motor structure in the above embodiment that directly drives the transmission disk 5 to rotate, preferably, a driving motor 12 is slidably arranged on the main body 1, a driving shaft 13 is fixed to the output end of the driving motor 12, a fourth gear 14 is fixed to the driving shaft 13, and a driving groove 15 adapted to the fourth gear 14 is constructed on the transmission disk 5. Specifically, a slide groove 16 is constructed on the main body 1, and the slide groove 16 is arranged along the axial direction of the driving shaft 13. A slider 17 is slidably connected in the slide groove 16. The driving motor 12 is fixed on the slider 17. A linear driving mechanism is arranged on the main body 1 to drive the slider 17 to slide along the slide groove 16 (the linear driving mechanism is not in the prior art, not shown in the figure, and will not be described here), thereby driving the driving shaft 13 (and the driving motor 12) to move along its axis; the driving groove 15 is constructed along the axial direction of the transmission disk 5 (the driving groove 15 is constructed at the rotating shaft position of the transmission disk 5), and when the slider 17 moves to its At one end of the stroke, the fourth gear 14 enters the driving groove 15, so that the driving shaft 13, the fourth gear 14, the driving groove 15 and the transmission plate 5 can rotate synchronously, that is, the driving motor 12 can directly drive the transmission plate 5 to rotate; when the slider 17 moves to the other end of its stroke, the fourth gear 14 moves out of the driving groove 15. At this time, only the driving shaft 13 is in the driving groove 15, and the two cannot transmit, so that the driving motor 12 cannot drive the transmission plate 5 to rotate when it is running, and then the transmission plate 5 can be driven by the third gear 11 to reduce the rotation speed.

[0047] As an alternative to the above-mentioned motor structure driving the third gear 11 to rotate, preferably, the fourth gear 14 is meshed with the third gear 11. Specifically, the diameter of the fourth gear 14 is smaller than that of the third gear 11. When the slider 17 moves to one end of its stroke, the fourth gear 14 enters the driving groove 15, at which time the third gear 11 and the fourth gear 14 are disengaged, and the transmission plate 5 can be directly driven to rotate through the transmission of the fourth gear 14 and the driving groove 15. When the slider 17 moves to the other end of its stroke, the fourth gear 14 moves out of the driving groove 15, at which time the third gear 11 and the fourth gear 14 are meshed, and the transmission of the fourth gear 14, the third gear 11, the second gear 10 and the first gear 9 can drive the transmission plate 5 to rotate at a reduced speed; the advantage of such a setting is that when the driving motor 12 drives the driving shaft 13 to rotate, the linear driving mechanism can drive the slider 17 to move along the sliding groove 16, and then the driving mode of the transmission plate 5 is switched to adapt to different working states of the bottom plate lifting mechanism.

[0048] It should be noted that the fourth gear 14 has a certain thickness. When the fourth gear 14 moves out of the driving groove 15, the fourth gear 14 first engages with the third gear 11 and then completely moves out of the driving groove 15 (when the fourth gear 14 is in the driving groove 15 and engages with the third gear 11, the driving shaft 13 does not rotate), that is, the driving shaft 13 always maintains transmission to the transmission disk 5, and tries to avoid angular deviation of the transmission disk 5, which will cause the position of the support plate 4 to change.

[0049] In another embodiment provided by the present invention, further, an inclined portion 18 is fixed in the main body 1, and a slide bar 19 is slidably connected to the inclined portion 18, and the slide bar 19 is fixed to the paperboard 2. Specifically, the inclined portion 18 is fixed in the main body 1 (the inclined portion 18 is located on the side of the paperboard 2 away from the center of the main body 1, and is suspended in the main body 1. For this purpose, a connecting rod 20 can be fixed on the inner wall of the main body 1, and the connecting rod 20 is fixed to the inclined portion 18 to limit the position of the inclined portion 18 through the connecting rod 20); an inclined groove is constructed in the inclined portion 18, and the slide bar 19 is inclined and slidably connected in the inclined groove (the end of the slide bar 19 and the inclined groove close to the center of the support plate 4 is lower), and in the process of the slide bar 19 sliding along the inclined groove, the paperboard 2 is tilted and moved along with the slide bar 19, and the driving force for the slide bar 19 to move along the inclined groove can be selected from the electric push rod and other structures in the prior art; the advantage of such a setting is that when the slide bar 19 drives the paperboard 2 away from the packaging paper along the inclined groove, the paperboard 2 moves upward. The paper pressing plate 2 moves in a direction away from the center of the tray while moving, until the paper pressing plate 2 moves to the second position, and the paper pressing plate 2 is on the side of the packaging paper (that is, the paper pressing plate 2 is not in the space directly above the packaging paper), so that the paper picking mechanism can adsorb the uppermost layer of packaging paper through the vacuum suction cup 3, so as to drive the uppermost layer of packaging paper to move vertically to a position higher than the paper pressing plate 2, and then the slide bar 19 drives the paper pressing plate 2 to return to the first position, and then the adsorbed packaging paper is placed on the paper pressing plate 2 by the paper picking mechanism, so that the preparation of the packaging paper is completed; in this embodiment, the reciprocating movement of the slide bar 19 can drive the paper pressing plate 2 to reciprocate between the first position and the second position, and then cooperate with the bottom plate lifting mechanism and the paper picking mechanism to move the uppermost layer of packaging paper onto the paper pressing plate 2.

[0050] As an alternative solution for the above-mentioned electric push rod structure to drive the slide bar 19 to move back and forth along the inclined groove, preferably, a turntable 21 is rotatably connected to the main body 1, and a hinged rod 22 is hinged on the turntable 21. One end of the hinged rod 22 is hinged to the turntable 21, and the other end is hinged to the slide bar 19. A first bevel gear 23 is fixed to the turntable 21, and a second bevel gear 24 is fixed to the drive shaft 13. Specifically, the turntable 21 and the first bevel gear 23 are coaxially fixed, and the first bevel gear 23 is located on the side of the turntable 21 away from the hinged rod 22. The turntable 21 and the hinged rod 22 are both tilted with the slide bar 19 (such as Fig.10As shown in the figure, the hinge point of the turntable 21 and the hinge rod 22 is at a position far away from the center of the turntable 21. During the rotation of the turntable 21, the hinge point of the turntable 21 and the hinge rod 22 reciprocates close to or away from the slide bar 19, so that when the turntable 21 rotates, the slide bar 19 is driven to reciprocate along the inclined groove through the hinge rod 22, thereby driving the paperboard 2 to reciprocate between the first position and the second position; the second bevel gear 24 is fixed to the end of the drive shaft 13 away from the drive motor 12. When the slide plate moves to the other end of the slide groove 16, the drive shaft 13 moves synchronously to drive the fourth gear 14 to mesh with the third gear 11. At this time, the first bevel gear 23 moves with the drive shaft 13 and meshes with the second bevel gear 24, that is, the drive shaft 13 can synchronously drive the turntable 21 to rotate when driving the upper transmission plate 5 to rotate at a reduced speed, thereby driving the paperboard 2 to reciprocate between the first position and the second position. The advantage of such an arrangement is that when the driving shaft 13 drives the transmission disk 5 above to decelerate and rotate, the paper pressing board 2 moves from the first position to the second position, which can release the restriction of the paper pressing board 2 on the packaging paper on the tray, so that the support plate 4 slowly rises under the drive of the transmission disk 5 and the transmission belt 6, thereby driving the packaging paper on the tray to slowly rise. During the rising process of the support plate 4, the paper picking mechanism moves the uppermost packaging paper to the top of the paper pressing board 2, and then the paper pressing board 2 is reset to the first position, and the paper picking mechanism places the packaging paper it has absorbed onto the paper pressing board 2. During the resetting process of the paper pressing board 2, its bottom can contact the remaining packaging paper on the tray again, that is, the driving shaft 13 is driven When the movable press board 2 completes a reciprocating movement (i.e., drives the press board 2 to move from the first position to the second position, and then resets from the second position to the first position), the paper picking mechanism operates adaptively to move the top layer of packaging paper onto the press board 2. At the same time, the bottom plate lifting mechanism operates adaptively to lift the tray to a certain height (the height of the tray 4 and the tray is lifted is approximately equal to the thickness of one packaging paper). In this way, the tray 4 and the press board 2 can be driven to operate adaptively through the continuous rotation of the drive shaft 13, and then the top layer of packaging paper on the tray is repeatedly placed on the press board 2 in the first position, so that the clamping structure of the packaging module can be used to package books.

[0051] In another embodiment provided by the present invention, further, a limiting mechanism for limiting the movement of the driving shaft 13 is included. The limiting mechanism includes an annular enclosure 25 fixed on the rotating disk 21, and an arc groove 26 is configured on the annular enclosure 25. Specifically, the annular enclosure 25 is fixed to one side of the turntable 21 close to the first bevel gear 23. When the first bevel gear 23 and the second bevel gear 24 are meshed, the first bevel gear 23 and the second bevel gear 24 are both located in the annular enclosure 25; in the above embodiment, when the first bevel gear 23 and the second bevel gear 24 are meshed, the driving shaft 13 rotates several times to drive the second bevel gear 24 and the turntable 21 to rotate one circle. During this process, the transmission plate 5 located above rotates a certain angle to drive the support plate 4 to lift a certain height. Before and after the above transmission is completed, the fourth gear 14 on the driving shaft 13 corresponds to the driving groove 15, so as to drive the fourth gear 14 to move into the driving groove 15 when the slide plate drives the driving motor 12 to move; based on the above movement process, the slide plate is preferably moved when the paperboard 2 is in the first position, so that the misalignment of the fourth gear 14 and the driving groove 15 can be avoided as much as possible. , and at the same time, it can drive the paperboard 2 to run stably after the slide plate switches its position. For this purpose, an annular enclosure 25 and an arc groove 26 are provided; when the first bevel gear 23 drives the paperboard 2 to move to the first position, the arc groove 26 of the annular enclosure 25 corresponds to the position of the second bevel gear 24 (the diameter of the arc groove 26 is substantially the same as the diameter of the second bevel gear 24. When the positions of the two correspond, the second bevel gear 24 moves with the drive shaft 13 and can pass through the arc groove 26 to enter the annular enclosure 25 or move out of the annular enclosure 25). At this time, the second bevel gear 24 can move with the drive shaft 13 to enter the annular enclosure 25 and mesh with the first bevel gear 23, or disengage from the first bevel gear 23 and move out of the annular enclosure 25; conversely, when the paperboard 2 has not moved to the first position, the arc groove 26 does not correspond to the second bevel gear. If the second bevel gear 24 moves with the drive shaft 13, it will conflict with the annular enclosure 25.The advantage is that, by setting a limiting mechanism, the movement of the drive shaft 13 can be limited when the paperboard 2 is not in the first position. When the slider 17 moves to one end of the slide groove 16, the fourth gear 14 enters the drive groove 15, and the second bevel gear 24 disengages from the first bevel gear 23 and moves out of the annular enclosure 25. At this time, the drive motor 12 drives the drive shaft 13 to rotate, which can directly drive the transmission plate 5 to rotate (after the second bevel gear 24 moves out of the annular enclosure 25, the positions of the two will not interfere with each other); when the slider 17 moves to the other end of the slide groove 16, the fourth gear 14 moves out of the drive groove 15 and meshes with the third gear 11. At the same time, the second bevel gear 24 enters the annular enclosure 25 through the arc groove 26 and meshes with the first bevel gear 23. When the drive shaft 13 rotates, the transmission disk 5 is driven to slow down and synchronously drive the paperboard 2 to reciprocate; in the above process, the second bevel gear 24 does not interfere with the annular enclosure 25, that is, the limiting mechanism is not running, which means that the device runs smoothly, and the position of the slide plate is adjusted when the paperboard 2 is in the first position; if during the movement of the slide plate, the second bevel gear 24 does not pass through the arc groove 26 and conflicts with other parts of the annular enclosure 25, it means that the first bevel gear 23 has not rotated to the specified angle, that is, the paperboard 2 is not in the first position, which will have a serious impact on the subsequent operation of the device. Based on this, the limiting mechanism can avoid the slide plate from running at the wrong time as much as possible, and the stability of the device operation can be improved as much as possible.

[0052] In the embodiment of the present invention, Figure 13-15 As shown, the packaging module consists of a feeding and book dropping mechanism ( Fig.14 )、Lifting mechanism、Book pushing mechanism( Fig.15 )、Side paper insertion mechanism 39、Upper and lower ear paper insertion mechanism ( Fig.13), a book-pulling mechanism and an outer cover shell. The packaging module drives the paper-pulling clamp 31 through the paper-pulling servo 34 to clamp the packaging paper (the packaging paper on the paperboard 2 in the above embodiments) lifted by the paper feeding module and transport it to the set position (the blanking baffle 35 has been adjusted to the corresponding paper receiving position by the servo motor), and the lifting mechanism is lifted; at the same time, the transport mechanism 30 transfers the books pre-shaped by the feeding module to the secondary shaping station, and the width adjustment mechanism (the width adjustment servo 32 is controlled by the system) and the length adjustment mechanism (the length adjustment servo 33 is controlled by the system) perform the second shaping on the books. After the shaping is completed, the blanking baffle 35 is released, and the books fall to the lifting mechanism. The lifting mechanism is lowered to the bottom surface, and the paper inserting mechanism (pushing module) inserts the packaging paper flat to fit the book (the upper paper inserting mechanism 37 and the upper paper inserting adjustment servo 38, the side paper inserting mechanism 39 and the side paper inserting adjustment servo 40 need to be set to the corresponding product specification position by their servos in advance to save equipment operation time and avoid damage to the product by misoperation). After completion, the book pushing mechanism (servo system control) of this module pushes the book to the book turning mechanism, which moves the book to the upper and lower ear paper inserting station and pushes the book to flow in this station. , the upper and lower ear packaging papers are flattened (the paper pressing mechanism 36 and the side paper inserting mechanism 39 of this station have been driven by the servo system to the size position of the corresponding product specifications), and the upper and lower ear paper inserting mechanisms (the upper ear paper inserting 27, the lower ear paper inserting 28 and the upper and lower ear paper inserting width adjustment servo 29 that drives them to operate) are driven by the cylinder to flatten the raised packaging paper and fit the book. At this point, the packaging paper book wrapping process is completed, and the book shifting servo system returns to the starting point; the discharging book shifting mechanism is driven by the cylinder to push the books and transfer them to the labeling and packaging circulation module.
