Description

Technical Field

[0001] The present invention relates to the technical field of automatic packaging, and particularly to a blanking device and a cartoning machine. Background Art

[0002] Plastic sleeves (including heat shrinkable tubes) are widely used due to their advantages such as insulation protection, environmental friendliness, durability, and special functions such as heat shrinkage and flame retardancy that can be achieved with special materials and processes.

[0003] Cartons are more suitable for customers and occasions with high standard requirements in terms of preventing folding and aesthetics. When cutting plastic sleeves and loading them into cartons, it is not smooth, and they are easily ejected from the cutting place, resulting in chaotic stacking. In addition, when discharging materials, due to the too large discharge port, the materials are discharged outside the packaging box, and there is no corresponding special box cartoning machine, so this process has long been manually operated.

[0004] In order to reduce labor costs and improve work efficiency, this blanking device and cartoning machine are developed. Summary of the Invention

Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts, and other implementation manners can also be obtained.

[0047] For the sake of simplicity of the drawings, only the parts related to the present invention are schematically shown in each drawing, and they do not represent their actual structures as products. In addition, for the sake of simplicity and easy understanding of the drawings, in some drawings, for components with the same structure or function, only one of them is schematically shown, or only one of them is marked. In this article, "one" not only means "only this one", but also means "more than one" situation.

[0048] The following will describe in detail a labeling device and a case packing machine according to an embodiment of the present application with reference to the accompanying drawings. Without conflict, the features in the following embodiments and implementation manners can be mutually supplemented or combined.

[0049] See Figure 1 and Figure 2, a cartoning machine 100 provided by the present invention is described. The cartoning machine provided by the present invention can integrate multiple processes such as automatic box loading, cutting, box covering, calibration and pressing of the box, pre-label pressing, label pressing, and box pushing through the cooperation of multiple processes, realizing automatic tube cutting, automatic box loading, and labeling work, which can improve the efficiency of the process and reduce the labor intensity of workers; it has a certain reference role in the fields of cutting box packaging, box covering packaging, multi-concave-convex platform labeling, and overall automatic box loading.

[0050] Specifically, the cartoning machine 100 includes a blanking device 110, a box covering device 120, a labeling device 130, a sealing device 140, and a box pushing device 150 that are sequentially arranged and installed on an indexing plate 50.

[0051] See Figure 2 , a cartoning machine 100 further includes an electrical box 40, sensors, and a frame 30. The electrical box 40 is electrically connected to the box covering device 120, the labeling device 130, the sensors, and the sealing device 140, and the sensors are electrically connected to the box covering device 120, the labeling device 130, and the sealing device 140.

[0052] See Figure 3 , Figure 4 and Figure 5 , the blanking device 110 is used to receive the strip material 10 at the blanking station and transfer the strip material 10 into the packaging box 20 during the downward movement. The blanking device 110 includes: a cutter 111, a housing 112, a pressing plate 113, a partition plate 114, an inclined plate 115, a first opening 116, and a second opening 117.

[0053] The cutter 111 is installed on the frame 30 and can cut the strip material 10. The housing 112 is installed on the cutter 111 and has a first opening 116 and a second opening 117. The first opening 116 is located on the side of the housing 112 close to the cutter 111 for inputting the strip material 10. The second opening 117 is located at the bottom of the housing 112 for outputting the strip material 10.

[0054] The pressing plate 113 is welded inside the housing 112 and is located above the second opening 117. The partition plate 114 is vertically installed below the pressing plate 113 and the included angle with the pressing plate 113 is an acute angle or a right angle. The inclined plate 115 is arranged at the bottom end of the housing to form a constricted opening.

[0055] It should be noted that the blanking device 110 provided by the present invention adopts a special design. The outer shell 112, the pressing plate 113, and the partition plate 115 surround to form a blanking groove, and the blanking groove has the first opening 116 and the second opening 117. The blanking groove adopts a special design. Since the widths of the multiple cut strip-shaped materials 10 are wider than the width of the packaging box 20, inner guide angles are provided on both sides of the lower part inside the blanking groove. The strip-shaped materials 10 are in the upper non-chamfered area of the blanking groove during cutting, which can prevent the cut strip-shaped materials 10 from having beveled edges. Then, during blanking, the strip-shaped materials 10 enter the packaging box 20 along the inner guide angles on both sides of the lower part inside the blanking groove under the action of gravity and the downward pressure of the pressing plate 13 of the specially designed blanking groove driven by the cutting cylinder.

[0056] The specially designed blanking groove also has the partition plate 114 in the vertical direction. The partition plate 114 can prevent the multiple strip-shaped materials 10 from interfering with each other in the horizontal direction when falling. The partition plate 114 can greatly reduce the situation of poor packaging caused by some of the strip-shaped materials 10 protruding outside the packaging box 20 due to mutual interference when the strip-shaped materials 10 fall, especially when the length of the cut strip-shaped materials 10 is relatively long, such as almost equal to the length of the packaging box 20; or when the number of strip-shaped materials 10 to be cut is relatively large, such as almost filling the entire packaging box 20.

[0057] See Figure 2 and Figure 6 , the box covering device 120 has a box covering preparation station and a box covering station. The box covering preparation station is provided with a box covering preparation device 121, and the box covering preparation device 121 includes: a third conveyor belt 122, a lifting member 123, a radial member 124, and a fastening member 125.

[0058] The third conveyor belt 122 is installed on the frame 30 and is used to convey the packaging box 20 from the blanking station to the box covering station. The box covering device is installed on the frame 30 and is located above the box covering station. The lifting member 123, the radial member 124, and the fastening member 125 are arranged adjacent to the conveying route of the third conveyor belt 122 in sequence along the conveying direction of the third conveyor belt 122. The lifting member 123 is installed on the frame 30, and along the conveying direction of the third conveyor belt, the height of the upper end surface of the lifting member 123 gradually increases. The radial member 124 is installed on the frame 30, and along the driving direction of the third conveyor belt 122, the radial dimension of the radial member 124 gradually increases towards the conveying route of the third conveyor belt 122. The fastening member 125 is installed on the frame 30 and has a gap with the third conveyor belt 122, and the gap between the fastening member 125 and the third conveyor belt 122 gradually decreases. Among them, when the uncovered packaging box 20 is conveyed and sequentially contacts the lifting member 123, the radial member 124, and the fastening member 125, the rotation pre-fastening of the box cover of the packaging box 20 is realized.

[0059] See Figure 7 , and there is a box covering mechanism 126 at the box covering station. The box covering mechanism 126 includes: a box covering block 127, a top piece 128, and a straightening mechanism 129.

[0060] The box covering block 127 is located above the box covering station, is installed on the frame 30 and can move up and down on the frame 30. When moving down, it rotates the box cover to complete the box covering action. The top piece 128 is fixedly connected to the box covering block 127. The top piece 128 has a working surface, and the working surface is an inclined surface or the box cover includes an inclined surface. When the working surface contacts the box cover, it pushes the box cover, and further makes the box cover move away from or close to the rotation axis; the straightening mechanism 129 includes a second twisting mechanism 1291 and a straightening rod 1292. The second twisting mechanism 1291 is installed on the frame 30, and the straightening rod 1292 is rotatably and movably fixed on the frame 30. The second twisting mechanism 1291 is connected to the straightening rod 1292 to make the straightening rod 1292 rotate. When the straightening rod 1292 approaches the box covering station, it contacts and acts on the side wall of the box cover to perform straightening; the first conveyor belt is used to convey the packaging box 20 from the box covering station to the labeling station.

[0061] Through the straightening mechanism 129 and the top piece 128, the left-right straightening and front-back alignment of the packaging box 20 can be realized respectively, and the function of covering the packaging box can be realized by moving the box covering block 127 downward; among them, the top piece 128 can also eject the cutting pieces that have not been removed during the production of the packaging box 20.

[0062] Specifically, the working surface of the top piece 128 is an arc surface. The second twisting mechanism 1291 is a cylinder, a hydraulic cylinder or a motor.

[0063] Specifically, the second twisting mechanism 1291 is a cylinder. One end of the cylinder is rotatably connected to the frame 30, and the other end of the cylinder is rotatably connected to the straightening rod 1292.

[0064] It should be noted that the cover box device 120 includes a middle cover box path plate that cooperates with the cutter 111 and the indexing plate to cover the packaging box 20. When the packaging box 20 rotates with the indexing plate, the upper part of the packaging box 20 sequentially contacts the vertical upper side, horizontal side, and vertical lower side paths of the cover box path plate. With the change of the side path and the relative position change of the upper part of the box cover, the function of closing the upper cover is realized. The box cover straightening cylinder in the cover box part can straighten the side deviation (the upper cover of the packaging box twists during path friction) that appears in the previous step, and then the pressing box cylinder (connected to the pressing box block) closes the packaging box 20. Finally, the cover box cylinder (connected to the covering block) is used to completely press the upper and lower parts of the packaging box 20, and acts on the end of the packaging box 20 for more sufficient pressing. The cover box straightening piece installed on the cover box block can straighten the upper part of the packaging box 20 when it is twisted in the front. And it can eject the redundant cutting pieces that are not removed during the production of the packaging box 20. This cutting piece position is used to hang the hook. The labeling part can convey a label to a fixed position each time and press it on the packaging box 20, and perform pre-pressing on both sides. Further, the label receiving part is wound under the drive of the servo motor. The label induction sensor senses the label gap and transmits it as a control signal to the PLC to control the start and stop of the winding servo motor, thereby controlling the conveyance of a label to a fixed position each time. The label feeding part is linked and stores the roll label. The labeling cylinder moves up and down to attach the label conveyed to the fixed position to the packaging box 20.

[0065] See Figure 2 and Figure 8 , the labeling device 130 for labeling the packaging box 20 at the labeling station includes: a first driving mechanism 131, a label pressing member 132, a labeling member 133, an elastic member 134, a pressing and folding mechanism 135, and a first conveyor belt 136.

[0066] The first conveyor belt 136 is installed on the frame 30, and is used to transfer the packaging box 20 from the cover box station to the labeling station. The first driving mechanism 131 is installed on the frame 30. The label pressing member 132 is located above the labeling station and is fixedly connected to the first driving mechanism 131 for up and down movement. The label pressing member 132 has a first pressing part and a second pressing part, and the first pressing part and the second pressing part are assembled together to form an L-shaped structure. The labeling member 133 is located below the first pressing part and can move on the second pressing part by sliding up and down. The elastic member 134 is located between the first pressing part and the labeling member 133, so that the first pressing part and the labeling member 133 have a distance that can move up and down. The folding mechanism 135 has a torsion spring, a rotating shaft and a pressing sheet. The rotating shaft is fixed on the labeling member 133, the pressing sheet is installed on the rotating shaft and is located below the second pressing part, and a torsion spring is also installed on the rotating shaft. Among them, after the label pressing piece 132 contacts the box cover for labeling, the first driving mechanism 131 drives the label pressing piece 132 to overcome the spring force and press down, so that the second pressing part pushes the pressing piece to rotate and form an indentation; after the label pressing piece 132 is separated from the pressing piece, the torsion spring causes the pressing piece to return to the action range of the second pressing part.

[0067] The labeling device 130 can drive the label pressing member 132 to move downward through the downward movement of the first driving mechanism 131. The label pressing member 132 presses the labeling member 133 downward through the spring to attach the label. The label pressing member 132 continues to press downward under the action of the first driving mechanism 131 to push the pressing sheet to fold the part of the label that exceeds the box cover.

[0068] Preferably, the label pressing member 132 includes two second pressing parts, and the first pressing part and the two second pressing parts are assembled to form a "冂"-shaped structure.

[0069] Specifically, a limiting groove is provided on the second pressing part, and a protruding piece is provided on the labeling piece 133. The limiting groove and the protruding piece match each other to limit the labeling piece 133 to move in the limiting groove.

[0070] Specifically, the folding mechanism 135 is a spring hinge, and the labeling member 133 has a spring hole.

[0071] It should be pointed out that the labeling cylinder of the labeling device 130 is connected and installed with a pre-stressed folding structure, which can control the pre-stressed folding spring hinges (hinge pieces) on both sides to embrace the folded label in the middle by the action of the spring during the downward pressing process. The folded label can provide good assistance for subsequent label pressing and eliminate the effect of poor label pressing. Because during the process of laminating the label with multiple concave and convex platforms, if the folds and shapes are not pre-folded, the flat paper label will not be successfully formed and pasted in one time, resulting in poor labeling such as wrinkles, non-lamination or misalignment.

[0072] See also Figure 2 and Figure 9, The sealing device 140 for sealing the packaging box 20 at the sealing station includes: a second conveyor belt 141, a sealing cylinder 142, a double-sided rack 143, two gears 144, and two sealing members 145.

[0073] The second conveyor belt 141 can move the packaging box 20 from the labeling station to the sealing station. The sealing cylinder 142 is installed on the frame 30. The double-sided rack 143 is mechanically connected to the packaging cylinder 142, and the sealing cylinder 142 is used to drive the double-sided rack 143 to perform a linear reciprocating motion in the vertical direction. The two gears 144 are fixed on the frame 30 through the transmission shaft 146 and are respectively located on both sides of the double-sided rack 143 and meshed with it. The two sealing members 145 are respectively installed on the two transmission shafts 146, and the working surface of the sealing member 145 matches the side wall of the packaging box 20.

[0074] The sealing device 140 can not only realize the functions of the above-mentioned box covering station and labeling station, but also realize the fitting of the label exceeding the box cover part by the sealing members 145 at the sealing station passing through the left and right fitting and squeezing the side wall of the packaging box 20.

[0075] Specifically, the sealing member is Z-shaped.

[0076] The above-mentioned sealing device 140 further includes: a pressing mechanism 147 and a third driving device 148. The pressing mechanism 147 is located between the two sealing members 145 and above the sealing station, and can press the label on the box cover from top to bottom under the drive of the third driving device 148.

[0077] The pressing mechanism 147 and the third driving device 148 can press the label on the upper box cover by driving the pressing mechanism 147 to move downward by the third driving device 148, so as to press the label tightly. Therefore, the third driving device 148 can also be called a label pressing cylinder, and the pressing mechanism 147 can also be called a pressing block.

[0078] It should be noted that the label sealing device 140 can press the label onto the packaging box, and the label stickers on both sides have a good degree of coincidence with the packaging box. Further, the label sealing cylinder 142 moves up and down to drive the double-sided rack to move up and down, driving the left and right gears to rotate synchronously, and then driving the transmission shaft 146 to rotate. The label sealing member 145 rotates with the transmission shaft 146 to press the label sticker. The shape of the label sealing member 145 is designed according to the two side edges of the packaging box 20, and the rear section and the front section of the label sealing member 145 can be adjusted in relative position to achieve a better fitting effect. The label pressing cylinder is connected to the label pressing block. Since the packaging box is elastic, when the label pressing block presses down and the double-sided clamping of the label sealing member 145, the convex platforms and the label are further pressed and fitted together to achieve a better labeling effect on the multi-convex platform. The box pushing part pushes the packaged finished product to the blanking frame. Further, the box pushing cylinder is connected to the box pushing block and horizontally moves to push out the packaged finished product. However, before this step, there is also a box lifting movement. With the rotational movement of the indexing disk, the box lifting rod moves under the action of the path of the box lifting path block to lift up the packaged finished product at the box pushing station. Removing the suction of the suction cup is beneficial to eject the packaged finished product, so that it falls into the finished product area. The box lifting path block is also designed so that during the operation of the rotary indexing disk, there is still a part of the suction force to prevent the packaged finished product from being thrown out due to insufficient suction force during the rotation process, and the suction force is removed until it reaches the box pushing station, which is convenient for box pushing. In addition, the equipment also includes an electrical box part (including electrical appliances such as a PLC controller), a blanking chute part (the box lifting path block is connected to the blanking chute), and an overall bracket, etc. Generally, the lower detection sensor between the box loading part and the cutting part is a proximity sensor, which senses whether the cylinder shaft of the suction cup is in the upward working state. If it is above and not sensed, it means that the suction cup is in the non-adsorbed state, which means that the box loading is stuck (the box is not loaded), and the signal is transmitted to the PLC to control the subsequent cutting part not to perform cutting for this non-box loading situation. Similarly, the lower detection sensor between the box covering part and the labeling part is also a proximity sensor, and no subsequent labeling operation will be performed for the non-box state. The equipment also includes various detection sensors, which can detect and alarm for the presence or absence of tubes and the presence or absence of missing boxes, etc.
