Description

Technical Field

[0001] The invention relates to the technical field of high-speed labeling, in particular to a single-station high-speed labeling machine using an intermittent action component. Background Art

[0002] High-speed labeling machines usually consist of a label supply device, a label taking device, a glue coating device, an attachment device and an overall control system. The label supply device is responsible for supplying label paper according to certain process requirements, and is usually composed of a label bin and a label pushing device. The label taking device accurately takes out the label from the label supply device through mechanical or pneumatic means and transfers it to the labeling position. For paste labeling machines and hot melt adhesive labeling machines, the glue coating device is the key part, which evenly coats the glue or hot melt adhesive on the label so that the label can be firmly attached to the product surface;

[0003] When the product arrives at the designated location, the attaching device will quickly and accurately attach the label with glue or the peeled backing paper to the surface of the product, and make the label fit the product closely by rolling, pressing, etc. to ensure the quality of the labeling. Usually, the labeling system uses control components such as PLC and touch screen to accurately control and coordinate each action of the labeling machine;

[0004] For example, the patent publication number CN119389570A mentions the use of vacuum sponge suction cups for label adsorption and pressing, emphasizing that the suction cup cannot make the label fit completely with the product surface. At the same time, the sponge suction cup itself will collapse after long-term use, affecting the overall labeling effect. Therefore, the problem is solved by adding a lightweight spring. However, it is only improved on the fitting suction cup and the spring is installed for fitting buffering. It is easy to cause uneven force on the label on the product due to the distribution of the spring. When the product surface is soft, the pressure of the label area contacted by the spring is greater than that of the area around the spring, which is easy to cause the label to curl and deform at the edge of the product. For this reason, we propose a single-station high-speed labeling machine with intermittent action components. Summary of the invention

[0005] The object of the present invention is to provide a single-station high-speed labeling machine using an intermittent motion component to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a single-station high-speed labeling machine using an intermittent action component, comprising a labeling table, a material storage reel, an adjustment roller and a guide roller are installed on one side of the labeling table, a transmission box is also installed on one side of the labeling table, and a circulating material taking mechanism is slidably connected to the transmission box;

[0007] The output end of the motor in the transmission box is fixedly connected with a turntable, and an electric push rod 2 is fixed to the back side of the labeling platform by bolts. The end of the electric push rod 2 is fixedly connected with the labeling platform, and the top of the labeling platform is movably connected with a transmission platform. The bottom belt side of the transmission platform is also movably connected with a transmission roller, and the transmission roller is in contact with the belt installed on the transmission platform.

[0008] Furthermore, the circulating material-feeding mechanism includes a cross frame and a lifting rod. The cross frame is installed on the top of the transmission box, and the cross frame is slidingly connected to the extended side of the transmission box. The cross frame and the extended side of the transmission box are sleeved with springs. The top side of the cross frame is movably connected to the lifting rod, and the end of the lifting rod is fixed to the placement frame by bolts.

[0009] Furthermore, the circulating material picking mechanism also includes a suction table and a pressing roller. The bottom of the placement rack is rotatably connected to the suction table, the suction table side is movably connected to the pressing roller through a bearing, the placement rack side is movably connected to an electric push rod 1 through a bearing, and one end of the electric push rod 1 is movably connected to the extended side of the suction table.

[0010] Furthermore, a stop block is installed on the side of the horizontal frame to abut against one side of the turntable, and a ball bearing is installed on the bottom of the lifting rod to abut against the other side of the turntable.

[0011] Furthermore, a tilting rod is rotatably connected in the through slot on the labeling platform, one end of the tilting rod is in contact with the side slot of the lifting rod, and one end of the tilting rod is movably connected to a pulling rod.

[0012] Furthermore, a transmission tooth is fixedly sleeved on the transmission roller on the labeling station side, the transmission tooth sleeve is movably connected with a transmission rod, and the end of the transmission rod is movably connected to one end of the pull rod.

[0013] Furthermore, the inner wall of the transmission rod is rotatably connected with a pawl 1 through a bearing, one side of the pawl 1 abuts against the transmission tooth, and the back side of the labeling platform is movably connected with a pawl 2, and the bottom of the pawl 2 abuts against the transmission tooth.

[0014] The single-station high-speed labeling method using intermittent action components is:

[0015] The rotary driven downward pressing labeling is performed on the labeling table. As the turntable on the transmission box side rotates, the suction table on the placement rack absorbs the label pushed out by the electric push rod 2. Then the turntable pushes the lifting rod to tilt up and pushes the entire horizontal frame to slide again under the continuous rotation of the turntable. Then the rotation of the lifting rod causes the suction table on the placement rack to press the label on the box surface, and the entire horizontal frame is reset under the push of the spring. As the horizontal frame moves, the electric push rod 1 pushes the entire suction table to rotate, causing the transmission roller on one side to contact the label on the box surface, completing the label rolling after bonding.

[0016] Intermittent drive feeding and laminating, with the lifting rod moving downward, the label is delivered to the box surface. At this time, the lifting rod is located at the back side of the labeling table and is lifted up, and the entire transmission rod is driven to rotate through the pull rod. At this time, the ratchet on the transmission rod does not drive the transmission roller to rotate, and the entire transmission platform is stationary, which is convenient for the precise docking of the box material and the label. With the upward movement of the entire lifting rod, the label is being picked up at this time, and the downward transmission rod pushes the entire transmission roller to rotate through the ratchet, and the rotation of the transmission roller is used to realize the rotation of the entire transmission platform, and the new box material is moved to the bottom of the suction table for cyclic laminating.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, a special structure turntable installed on the side of the transmission box is used as a medium, and the turntable itself is used to rotate to realize the combined movement of the horizontal frame and the lifting rod, and the suction table installed on the side of the placement frame is controlled to adsorb a single label on the side of the label pushing table, and the label on the side of the suction table is automatically attached to the top of the box material under the movement of the lifting rod. The overall label attachment efficiency is high, and the subsequent placement frame movement is coordinated with the suction table attachment angle control by the electric push rod, so that the pressing roller contacts the attached label during the movement, and the roller pressure improves the overall label attachment effect;

[0019] 2. In the present invention, the lifting rod is used to control the label on the suction table side, and the pull rod connected to the tilting rod on the other side can also control the rotation angle of the transmission rod on the transmission roller side. The opposite motion trajectories of the lifting rod and the pull rod are used to adjust the rotation of the transmission teeth, and the ratchet one and the ratchet two are abutted to realize the fixed distance rotation of the transmission table connected to the transmission roller, which is convenient for the synchronous control of the bonding of the box material and the label, further improving the overall bonding efficiency. At the same time, there is no need to set up an independent feeding drive mechanism for box material control, so that the overall power consumption of the single-station high-speed labeling machine is reduced.

DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figure 1-7 , the present invention provides a technical solution:

[0030] Example 1: Figures 1 to 7 As shown, the present invention is a single-station high-speed labeling machine using an intermittent action component, including a labeling table 11, a transmission box 55, a circulating material taking mechanism 77 and a transmission system. The circulating material taking mechanism 77 is used to synchronously drive the transmission system, and a re-pressing operation after label bonding can also be performed, thereby improving the entire labeling rate and label bonding effect;

[0031] The labeling platform 11 is a metal frame structure with through grooves and mounting positions on the surface. A material storage reel 22, an adjusting roller 33 and a guide roller 44 are installed on one side for stable conveying of the label tape. The adjusting roller 33 adjusts the tightness through a screw to ensure that the label tape does not deviate during the transmission process. The guide roller 44 is made of rubber with anti-skid patterns on the surface to further enhance the positioning accuracy of the label tape.

[0032] Fix the label roll placed on the material storage reel 2, wind the label along the adjacent side adjustment roller 3, and then extend it to the label pushing platform 9 on the side of the labeling platform 1 through the guide roller 4. Figure 1 and Figure 5As shown, the front end of the label pushing platform 9 is relatively thin, and limit blocks are installed on both sides of the top to prevent the label roll from deviating when it moves. By installing the label pushing platform 9, the release paper at the rear side can be separated from the label, and the label is pushed to the side of the circulating material taking mechanism 7, which is convenient for the subsequent suction platform 704 to adsorb the label;

[0033] like Figure 2 and Figure 4 As shown, the main body of the entire circulating material-taking mechanism 7 is installed on both sides of the transmission box 5, wherein one side of the cross frame 701 is sleeved on the outer column of the transmission box 5, and a spring 706 is sleeved and installed between the two, and a lifting rod 702 is rotatably connected to the cross frame 701 on the top of the transmission box 5, and a placement frame 703 is fixed to both sides of the end of the lifting rod 702 by bolts, and a suction table 704 for label adsorption is installed on the inner side of the placement frame 703 and is rotatably connected to the placement frame 703. Similarly, an electric push rod 707 is movably connected to the extended side of the suction table 704, and the suction table 704 can be driven to adjust the angle of the pressing surface by the extension of the electric push rod 707, and a pressing roller 705 is also movably connected to the side of the suction table 704. When the angle of the suction table 704 is adjusted, the pressing roller 705 connected to the other side rotates in the opposite direction;

[0034] For driving the entire circulating material taking mechanism 7, a turntable 6 is installed on the side of the transmission box 5. The turntable 6 is an eccentric disk structure as a whole, and a convex arc surface is also arranged on the outer side thereof. The inner side of the cross frame 701 abuts against the convex end surface of the turntable 6 through a column, and the bottom ball of the lifting rod 702 installed on the cross frame 701 also abuts against the outer rolling surface of the turntable 6.

[0035] The entire motion trajectory of the suction table 704 is described. The turntable 6 of the eccentric disk structure gradually pushes the entire top abutting lifting rod 702 to move upward. At this time, the electric push rod 28 pushes the label pushing table 9 to move toward the suction table 704. When the suction table 704 is located at the top of the label pushing table 9, as shown in FIG. Figure 7 As shown in the middle mark material taking, the suction table 704 obtains the label by suction, and as the turntable 6 continues to rotate, the end surface of the turntable 6 also starts to push the entire horizontal frame 701 to move to the right, and the lifting rod 702 moves to the highest point. Then the lifting rod 702 moves downward due to the change of the rolling surface, pressing the label adsorbed by the suction table 704 on the box surface, and then the entire end surface is limited and the crossbar side spring 706 pushes, causing the entire cross frame 701 to start sliding to the left;

[0036] During the sliding process, the electric push rod 707 on the placement frame 703 pushes the suction table 704 to rotate, so that the pressing roller 705 on the other side begins to contact the surface of the label just attached, and the label and the box body are fully in contact while rolling. Compared with direct pressing and attaching, it is easy to cause the label to warp due to uneven force or instantaneous deformation of the box body, and in serious cases, the attached label will fall off;

[0037] Repeat as Figure 7 The suction table 704 shown in the figure moves, and the electric push rod 2 8 is also required to carry the label pushing table 9 to slide telescopically to achieve rapid loading and stable laminating of the entire label.

[0038] Embodiment 2: Since the entire single-station high-speed labeling machine is also equipped with a box material conveying control system, compared with the independently controlled feeding mechanism, the overall cost of the equipment is reduced and the adjustment is more convenient, such as Figure 2 and Figure 3 As shown, a transmission platform 12 is also provided at the bottom of the entire labeling platform 1, and a conveyor belt is covered on the transmission platform 12. The box material is moved to the bottom of the suction platform 704 by the rotation of the conveyor belt to complete the work of laminating the label with the box surface;

[0039] In order to control the rotation of the transmission belt on the transmission platform 12, a transmission roller 13 is movably connected to the bottom of the transmission platform 12. The transmission roller 13 is used to fit the bottom of the transmission belt on one side. The friction generated by the rotation of the transmission roller 13 drives the entire transmission belt to rotate, and at the same time facilitates the precise fitting of the label and the box surface. The movement distance of the box body on the top of the transmission platform 12 must be consistent each time;

[0040] A transmission gear 14 is installed on the transmission roller 13 side at the bottom of the transmission platform 12, and a transmission rod 15 is movably connected to the transmission gear 14 side. Figure 5 It can be understood that a tilting rod 10 is rotatably connected to the labeling platform 1, and a movable roller at one end of the tilting rod 10 abuts against the outer groove of the lifting rod 702. As the lifting rod 702 performs a lifting and lowering movement when the turntable 6 rotates, the abutting end of the tilting rod 10 moves synchronously, and the tilting rod 10 will not be affected when the lifting rod 702 moves;

[0041] The tilting rod 10 is located on the back side of the labeling platform 1 and is also movably connected to the pull rod 11. One end of the pull rod 11 is slidably abutted against the transmission rod 15, and the movement path of the entire pull rod 11 is opposite to the lifting rod 702. When the entire lifting rod 702 rotates upward, the pull rod 11 moves downward and pushes the transmission tooth 14 connected to the entire transmission rod 15 to rotate clockwise. A ratchet 16 is rotatably connected to the inner side of the transmission rod 15. The ratchet 16 abuts against the transmission tooth 14 through an elastic element, and a ratchet 2 17 is also installed on the inner side of the labeling platform 1. The ratchet 2 17 also abuts against the transmission tooth 14 to limit the rotation of the transmission tooth 14 and prevent the box material on the transmission platform 12 from shifting.

[0042] On the contrary, when the pull rod 11 moves upward, under the limit of the second pawl 17, the first pawl 16 cannot drive the entire transmission tooth 14 to rotate, causing the transmission rod 15 to idle at this time. Through the movement adjustment of the transmission rod 15 that is lifted and then pressed down once, the transmission roller 13 connected to the transmission tooth 14 can rotate at a fixed angle, which is convenient for the subsequent pushing of the box material on the transmission platform 12 to move at a fixed distance;

[0043] Combined with the movement trajectory of the suction table 704, when the lifting rod 702 rises to pick up materials, the pull rod 11 at this time pushes the ratchet 16 on the transmission rod 15 to move, pushing the entire transmission platform 12 to rotate and pushing the box material to move, and then the suction table 704 slides downward, and the pull rod 11 at this time moves upward for idling, to avoid displacement during the vacuum adsorption label pressing process at the bottom of the suction table 704, affecting the label bonding accuracy, and the entire circulating material picking mechanism 7 can be controlled by rotating the turntable 6 to perform label adsorption and bonding, and complete the rolling of the transmission roller 13 during the label bonding process to improve the overall bonding effect, and the intermittent movement of the box material can also be controlled synchronously, and the seesaw structure of the tilting rod 10 connects the lifting rod 702 and the pull rod 11, and drives the transmission gear 14 on the side of the transmission platform 12 to rotate at a fixed angle while the lifting rod 702 moves, so that the entire box material can move intermittently on the transmission platform 12, and the label and the box material can be accurately bonded.

[0044] The working principle of the present invention is as follows: the material storage reel 2 is threaded on the labeling table 1, and the label tape extending from the material storage reel 2 passes through the single-side adjustment roller 3 and multiple guide rollers 4 in turn to the label pushing table 9, and as the turntable 6 on the side of the transmission box 5 rotates, the side suction table 704 of the placement frame 703 absorbs the label pushed out by the electric push rod 2 8, and then the turntable 6 pushes the lifting rod 702 to tilt up and pushes the entire horizontal frame 701 to slide again under the continuous rotation of the turntable 6, and then the rotation of the lifting rod 702 causes the suction table 704 on the placement frame 703 to press the label on the box surface, and the entire horizontal frame 701 is reset under the push of the spring 706, and as the horizontal frame 701 moves, the electric push rod 1 707 pushes the entire suction table 704 to rotate, causing the transmission roller 13 on one side to contact the label on the box surface, completing the label rolling after bonding;

[0045] As the lifting rod 702 moves downward, the label is delivered to the box surface. At this time, the lifting rod 10 is lifted at the back side of the labeling platform 1, and the entire transmission rod 15 is driven to rotate through the pull rod 11. At this time, the ratchet 16 on the transmission rod 15 does not drive the transmission roller 13 to rotate, and the entire transmission platform 12 is stationary, which is convenient for the precise docking of the box material and the label. As the entire lifting rod 702 moves upward, the label picking work is being carried out at this time, and the downward transmission rod 15 pushes the entire transmission roller 13 to rotate through the ratchet 16, and the rotation of the transmission roller 13 is used to realize the rotation of the entire transmission platform 12, and the new box material is moved to the bottom of the suction table 704, and the material is circulated.
