Description

Technical Field

[0001] The invention relates to the technical field of palletizing robots, in particular to a rotary book signature palletizing robot. Background Art

[0002] The rotary press is the most commonly used printing equipment in printing companies. It has a fast printing speed, high efficiency, and can print both the front and back sides at the same time. It is also equipped with an automatic folding and cutting device, which can output book signatures of the same size one by one, and stack multiple folded book signatures into a pile of a certain height. The stacked book signatures are then stacked together by a stacking robot for subsequent handling or other processes.

[0003] For example, Chinese patent CN218707270U discloses a rotary book label clamping mechanism and a rotary book label stacking robot, which clamps stacked book labels by an upper book clamping board and a lower receiving board to perform a stacking process;

[0004] However, after the stacks of book signatures are stacked, the connecting paper is pulled out from under the book signatures by means of horizontal extension. Since the book signatures are not bound after being folded, their paper strength is still relatively low. This method may cause the connecting paper to rub the paper of the book signatures in contact with it when it is pulled out, which may cause creases or even damage to the contact surface between the two stacks of book signatures, thereby causing deep crease marks on the stacked book signatures. Summary of the invention

[0005] The object of the present invention is to provide a rotary signature stacking robot to solve at least one technical problem existing in the above-mentioned prior art.

[0013] Preferably, the outer walls of the two vertical bars are each provided with a second long groove, and the two pin sliders are respectively slidably installed in the two second long grooves, the upper section of the transmission belt is a horizontal section, the lower section is an inclined section, and the inclined section is designed to be inclined downward from the inside to the outside.

[0014] Preferably, a clamping paper is vertically slidably mounted on the bottom of the lower pressing plate via a guide rod, and a plurality of evenly distributed elastic members are connected between the clamping paper and the lower pressing plate.

[0015] Preferably, two side panels are fixed on the top of the horizontal plate, and the opposite surfaces of the two side panels are installed with limiting angles, and a storage chamber for storing partition members is formed between the limiting angles and the horizontal plate. The outer wall of the vertical plate is also provided with a discharge trough for the partition members to extend out, and the top of the horizontal plate is also installed with an electric slide plate that can slide horizontally and push the partition members out of the discharge trough.

[0022] Second, when the receiving rod is separated from the book sheet, the lower pressure plate provides downward pressure on the book sheet, which can not only prevent the book sheet from tilting during stacking, but also, under the action of pressure, the friction between the receiving rod and the book sheet above and below it will be further increased, thereby improving its smoothing effect. In addition, the effect of pressure can further compress the book sheet after stacking, further improving its stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 9 The present invention provides a technical solution: a rotary book signature stacking robot, comprising a clamping member mounted on a robot arm 1 through a mounting frame 3, the clamping member comprising a vertical plate member 2 and a horizontal plate member 4 fixed vertically to each other, and further comprising:

[0035] The paper receiving part installed on the vertical plate 2 includes two sets of receiving parts symmetrically arranged about the vertical center line of the mechanical arm 1, and the two receiving parts can be moved toward or away from each other in the horizontal direction;

[0036] The paper clamping part installed on the vertical plate 2 can be moved and adjusted in the vertical direction, and cooperates with the paper receiving part to clamp and fix the book signature when pressed down.

[0037] When the rotary book signature stacking robot is in use, the mechanical arm 1 is used to control the clamping member on it to move and adjust between the conveyor belt and the stacking position, so as to perform the stacking process on the book signatures that have been stacked on the conveyor belt;

[0038] In the clamping stage, the paper clamping part will first move vertically upward to provide space for the book signatures to be placed. When the stacked book signatures enter the two receiving parts below, Figure 1 and Figure 3As shown, the two receiving parts are in a state of being close to each other at this time, providing a bearing surface for the signature, and then the paper clamping part moves down to clamp and fix the signature, and when the robot arm 1 is used to transport it to the stacking position, the receiving part is made to contact with the stacked signature below, and then the external structure controls them to move away from each other in the horizontal direction until the receiving part is separated from the signature above it, completing the stacking process of the signature;

[0039] It is worth mentioning that since the signature will present a rectangular shape after folding, please refer to Figure 7 As shown, when clamping and transporting it, it will be clamped along its length direction, which can not only facilitate the clamping and fixing of the book signature, but also prevent the folding pages below the book signature from unfolding during the transportation process. Therefore, in this case, the receiving parts are disengaged by moving away from each other horizontally, so that the receiving parts and the folding lines of the book signature can be in a parallel state. Such a disengagement method can not only prevent the folding pages from being opened, but also further indent the folding lines of the folding pages, smoothing the bottom surface of the book signature and the top surface of the book signature below from the inside to the sides, ensuring that the contact surfaces of the book signatures during stacking remain in a complete contact state, avoiding the phenomenon of rubbing and wrinkling between the two, and further improving the stability of stacking.

[0040] In one of the more preferred embodiments, an implementation of a receiving portion is provided;

[0041] The outer wall of the vertical plate 2 is provided with a transverse groove 5, and the receiving part includes a plurality of transverse sliders 6 slidably installed in the transverse groove 5, and the outer wall of each transverse slider 6 is fixed with a paper receiving rod 7, and the outer wall of the vertical plate 2 near the notch of the transverse groove 5 is also fixed with a fixing block 21, and the adjacent two transverse sliders 6 and the adjacent transverse sliders 6 and the fixing block 21 are rotatably connected with a connecting rod structure, and the connecting rod structure includes two connecting rods 20 hinged to each other, and a torsion spring is provided between the two connecting rods 20;

[0042] Vertical bars 16 are fixed on the two horizontal sliding blocks 6 that are close to each other between the two receiving parts, and the two vertical bars 16 can be adjusted to move closer to or farther from each other.

[0043] For details, please refer to Figure 6 and Figure 7 First, in the load-bearing stage, the two vertical bars 16 are driven by the external structure to approach each other, and the adjacent horizontal sliders 6 are evenly pulled apart under the connecting action of the connecting rod 20, so that the paper receiving rods 7 are spaced apart to form a receiving plane, such as Figure 7 Status shown;

[0044] Then, when the receiving rod 7 carries the book to the stacking position, the two vertical bars 16 will be driven away from each other by the external structure, and at the same time, under the connection of the connecting rod 20, the horizontal sliders 6 on both sides will move toward the fixed blocks 21 on both sides, so that the receiving rod 7 moves to both sides until it is out of contact with the bottom surface of the book, completing the stacking process of the book. In this way, the receiving rod 7 can sweep the bottom surface of the book horizontally to smooth the bottom surface, so as to avoid the phenomenon of page bending.

[0045] It is worth mentioning that the length of the paper receiving rod 7 is preferably greater than the width of the book sheet, so that it can be more stable when receiving and more comprehensive when flattening. Even if there are wrinkles underneath, they can be smoothed out and flattened again in the subsequent stacking process.

[0046] It is worth noting that the torsion springs between the connecting rods 20 are provided to enable the two adjacent cross slide blocks 6 to move as synchronously as possible during movement, so as to prevent the spacing difference between the cross slide blocks 6 from being too large. At the same time, the connecting rod 20 can also be replaced by a scissor-type telescopic frame, which can also achieve the same function and effect.

[0047] In one of the more preferred embodiments, an implementation of a paper clamping portion and an adjustment method thereof are provided;

[0048] The paper clamping part includes a vertical groove 8 provided on the outer wall of the vertical plate 2, a vertical slider 9 is vertically slidably installed in the vertical groove 8, a lower pressing plate 10 is fixed to the outer wall of the vertical slider 9 located above the paper receiving rod 7, a horizontal bar 13 is fixed to the outer wall of the vertical slider 9 located above the connecting rod 20, and first long grooves 14 are provided on the outer walls of both sides of the horizontal bar 13;

[0049] The outer walls of the vertical plate members 2 located on both sides of the vertical groove 8 are installed with driving parts, and the two driving parts are symmetrically distributed about the vertical groove 8. The driving parts are composed of multiple transmission wheels 18 rotatably installed on the outer walls of the vertical plate members 2 and transmission belts 19 connected between the transmission wheels 18, and the transmission belts 19 form a quadrilateral structure with two vertical sections. The rotation directions of the transmission wheels 18 located on both sides of the vertical slider 9 are opposite. The inner walls of the two first long grooves 14 are horizontally slidably installed with pin sliders 15, and the two pin sliders 15 are rotationally connected to the side walls of the two transmission belts 19 through pin shafts.

[0050] For details, please refer to Figure 4-6 In the clamping or loosening process, the transmission belt 19 is driven by the rotation of the transmission wheel 18. Since the rotation directions of the transmission wheels 18 on both sides are opposite, the transmission directions of the two transmission belts 19 are also opposite. Figure 5 In the direction indicated by the arrow in the figure, during the transmission process, the two pin sliders 15 will be driven by the pin shaft to slide on the inner walls of the two first long grooves 14. Figure 5When the section a in the drawing moves, the pin slider 15 will drive the horizontal bar 13 to move downward, thereby driving the vertical slider 9 and the lower pressing plate 10 to slide downward to complete the clamping work of the signature;

[0051] Similarly, when the book signature needs to be released from the clamping function, the continued transmission of the transmission belt 19 will drive the pin slider 15 to move from section b to section c, thereby driving the horizontal bar 13 to move upward, and then driving the vertical slider 9 and the lower pressure plate 10 to slide upward to release the clamping of the book signature. In this way, the switching between the two states can be completed by controlling the rotation of the transmission wheel 18, and the transmission wheel 18 can be controlled and driven by an existing motor or motor;

[0052] It is worth mentioning that the reset can be completed by finally transmitting from section c to section d back to section a, and the transmission wheel 18 and the transmission belt 19 are preferably transmitted in the form of sprockets and chains to avoid slipping during the transmission process.

[0053] In one of the more preferred embodiments, the outer walls of the two vertical bars 16 are each provided with a second long groove 17, and the two pin sliders 15 are respectively slidably installed in the two second long grooves 17, the upper section of the transmission belt 19 is a horizontal section, and the lower section is an inclined section, and the inclined section is designed to be inclined downward from the inside to the outside.

[0054] See also Figure 5 From the above content, it can be concluded that when the pin shaft and the pin slider 15 move in the b section and the d section, the pin slider 15 will complete the reciprocating movement in the first long groove 14, that is, the two pin sliders 15 will complete the movement of being relatively close to or away from each other. Therefore, in this process, the two pin sliders 15 will drive the vertical bars 16 to move away from each other, thereby completing the separation process of the paper receiving rod 7 during the stacking of the book signatures. At the same time, the arrangement of the first long groove 14 and the second long groove 17 will not cause the two processes to conflict, and at the same time, their sequence can be maintained;

[0055] When segment b is designed as Figure 5 In the inclined section shown, the pin slider 15 stops when sliding to the connection between section a and section b, thereby achieving a pressing effect on the signature;

[0056] The setting of section b can make the book signatures in the stage of stacking, that is, when the lower paper receiving rod 7 moves to both sides, the transmission belt 19 continues to transmit, and the two pin sliders 15 drive the two vertical bars 16 to move away from each other, while the pin slider 15 also drives the horizontal bar 13 to move downward a small distance. The downward movement can be used to make the lower pressure plate 10 provide downward pressure on the book signatures, which can not only prevent the book signatures from tilting during stacking, but also, under the action of pressure, the friction between the upper and lower book signatures contacted by the paper receiving rod 7 will be further increased, thereby improving its smoothing effect, and the effect of pressure can make the book signatures further compacted after stacking, further improving its stability.

[0057] In one of the more preferred embodiments, a clipboard 11 is vertically slidably mounted on the bottom of the lower pressing plate 10 via a guide rod, and a plurality of evenly distributed elastic members 12 are connected between the clipboard 11 and the lower pressing plate 10 .

[0058] See also Figure 4 The design of the clamping board 11 and the elastic member 12 can prevent the lower pressing plate 10 from exerting excessive pressure on the signature and causing damage during the above process, while providing sufficient pressing force.

[0059] In one of the more preferred embodiments, two side panels 26 are fixed to the top of the horizontal plate 4, and the opposite surfaces of the two side panels 26 are installed with limiting angles, and a storage chamber for storing the partition member 23 is formed between the limiting angles and the horizontal plate 4. The outer wall of the vertical plate 2 is also provided with a discharge trough 25 for the partition member 23 to extend out, and the top of the horizontal plate 4 is also installed with an electric slide plate 22 that can slide horizontally and push the partition member 23 out of the discharge trough 25.

[0060] Due to the strength of the signatures, stacking too high will cause the signatures at the bottom to be severely compressed and deformed. Therefore, a partition 23 can be placed between the signatures to disperse the pressure and protect them from damage as much as possible. For specific forms, please refer to Figure 2 and Fig. 9 , the partition member 23 can be pushed out from the discharge chute 25 by the electric slide 22, so that it can fall on the top surface of the stack below, thereby forming a partition;

[0061] At the same time, the design of the storage chamber can also enable the partition member 23 to complete the function of automatic unloading, which can avoid multiple manual loading. Fig. 9 As shown;

[0062] Moreover, it is worth mentioning that the electric skateboard 22 and the partition member 23 have the same thickness, and when the electric skateboard 22 pushes the partition member 23 out of the discharge chute 25, the electric skateboard 22 can support the partition member 23 in the storage chamber to prevent the partition member 23 from falling prematurely, so that it can fall again after the electric skateboard 22 is reset, providing preparation for the subsequent addition of partitions.

[0063] It is worth noting that the partition member 23 can also play a certain identification role, because the types of book signatures that may be stacked may be different, and the partition member 23 can be used to play the role of isolation and identification. The thickness of the partition member 23 can also be designed to be greater than the diameter of the paper receiving rod 7, and a through hole for the paper receiving rod 7 to penetrate can be opened in the partition member 23. In this way, even if it is necessary to extract book signatures on different partition members 23, the paper receiving rod 7 can be inserted into the through hole on the partition member 23 to extract all the partition members 23 and the book signatures thereon, so as to facilitate the classified extraction of different types of book signatures.

[0064] In one of the more preferred embodiments, the partition member 23 is made of a material that can be magnetically attracted, and a built-in magnetic core 24 is embedded in the interior of each paper receiving rod 7. When the partition member 23 extends from the discharge chute 25, the partition member 23 is in tangential contact with the outer wall of the paper receiving rod 7.

[0065] See also Figure 8 In order to improve the stability of the partition member 23 when it extends from the discharge chute 25, the magnetic attraction of the built-in magnetic core 24 in the paper receiving rod 7 is utilized, which will not cause excessive friction between the partition member 23 and the paper receiving rod 7, and at the same time can play a role of magnetic guidance for the partition member 23.

[0066] In one of the more preferred embodiments, the paper receiving rod 7 is configured to be bent, and the cross section is configured to be circular. The configuration of the circular columnar body can achieve a better smoothing effect.

[0067] In one of the more preferred embodiments, the mounting frame 3 is fixed between the vertical plate member 2 and the horizontal plate member 4 by bolts, and the vertical plate member 2 and the horizontal plate member 4 form an integral structure.

[0068] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
