Description

Technical Field

[0001] This utility model relates to the field of automated labeling equipment technology, and in particular to a labeling machine. Background Technology

[0002] During the product manufacturing process, various labels are affixed to the product or its packaging. These labels serve functions such as identification, item tracking, and information collection.

[0003] In the application of flat labels, existing labeling machines feed a stack of flat label sheets one by one into the label holder for a brief period of time. At this time, a flat label sheet includes a release liner and multiple flat labels pasted on the release liner. Then, the rotation of the first adhesive roller pushes and moves the flat label sheet horizontally, thus feeding the sheet. Finally, the suction of the label suction head peels the flat labels off the release liner and pastes them onto the product or product packaging.

[0004] Because flat label sheets are inherently flexible, and when their size is large, existing labeling machines lack a guiding structure between the limiting frame and the first adhesive roller. This causes the flat label sheet inside the limiting frame to align poorly with the discharge port of the limiting frame during the feeding process of the first adhesive roller. Consequently, the flat label sheet is blocked by the end face of the limiting frame, resulting in wrinkles and reducing the feeding accuracy and stability of the flat label sheet. Furthermore, the existing labeling machines do not position the flat release paper securely enough. During the process of the label suction head peeling the flat label off the flat release paper, the release paper is prone to loosening, leading to longer peeling time and reduced production efficiency. Utility Model Content

[0005] In order to achieve the main objective of this utility model, this utility model provides a labeling machine with high efficiency, automation in label feeding, peeling, and labeling operations, high precision and good stability, thereby improving the accuracy, stability and reliability of the operation, and thus improving the quality of operation and production efficiency.

[0006] To achieve the main objective of this utility model, a labeling machine is provided, comprising a feeding device, a positioning device, and an adsorption device. The feeding device includes a material base, a feeding mechanism, multiple first rubber rollers, second rubber rollers, a suction cup, and a lifting mechanism. The material base has a material cavity with an opening at the bottom of one side. Multiple first rubber rollers are arranged side-by-side in the X-axis direction and rotatably supported at the bottom of the material cavity. The feeding mechanism controls the rotation of multiple first rubber rollers near the opening. The positioning device includes a support plate, a movable seat, a moving mechanism, a first clamping plate, a first mechanism, a second clamping plate, and a second mechanism. The feeding end of the support plate is inserted into the opening to form a feeding port. The peeling end of the support plate has an outlet, and a guide rail is provided above the peeling end of the support plate. The lower end face of the guide rail is curved downwards and extends in an arc shape to form a downwardly curved and extended discharge channel with the discharge port. The movable seat is located below the discharge channel. The moving mechanism controls the movable seat to move in the Z-axis direction. The first mechanism is set on the movable seat and controls the first clamping plate to move toward or away from the second clamping plate. The second mechanism is set on the movable seat and controls the second clamping plate to move toward or away from the first clamping plate. The adsorption device includes a transfer mechanism and an adsorption plate. The transfer mechanism controls the adsorption plate to move. The lower end face of the adsorption plate is provided with multiple suction nozzles. The suction cup is located at the bottom of the material cavity and is set near the feeding port. The lifting mechanism controls the suction cup to move in the Z-axis direction. The second rubber roller is located above the support plate and rotates and is supported on the material seat. The second rubber roller moves toward the support plate.

[0007] As can be seen from the above scheme, during the operation of the labeling machine of this utility model, a stack of flat label sheets is placed in the material cavity of the material seat of the feeding device, so that multiple first rubber rollers located at the bottom of the material cavity and arranged side by side in the X-axis direction stably support the stack of flat label sheets in the material cavity. When it is necessary to feed and label the bottom flat label sheet of the stack of flat label sheets, the lifting mechanism of the feeding device controls the suction cup to move upward in the Z-axis direction towards the bottom flat label sheet to adsorb the end of the bottom flat label sheet near the feeding port. Then, the lifting mechanism controls the suction cup to move downward in the Z-axis direction towards the end of the bottom flat label sheet near the feeding port until it is flush with the feeding port. The new type of feeding port is formed by inserting the feed end of the support plate into the through-hole and forming a gap between them. Then, the feeding mechanism controls the rotation of multiple first rubber rollers near the feeding port. At the same time, the suction cup releases the bottom flat label sheet near the feeding port, and the lifting mechanism controls the suction cup to move away from the bottom flat label sheet in the Z-axis direction. This allows the bottom flat label sheet near the feeding port to be accurately fed into the feeding port in the X-axis direction, avoiding misalignment between the bottom flat label sheet and the feeding port, which would cause the bottom flat label sheet to be blocked and wrinkled. This ensures that the bottom flat label sheet in the material cavity is accurately and stably fed into the feeding port and the support plate of the positioning device.

[0008] As the feeding mechanism controls the rotation of multiple first rubber rollers near the feeding port, the flat label sheet at the bottom of the material cavity continues to move towards the peeling end of the support plate in the X-axis direction. Since the peeling end of the support plate has a discharge port, and the support plate has a guide rail above its peeling end, with the lower end of the guide rail curved downwards in an arc shape to form a downward-curved arc-shaped discharge channel with the discharge port, one end of the flat label sheet moving to the peeling end of the support plate smoothly passes through the discharge channel under the guidance of the downward-curved arc-shaped discharge channel. As the material moves downwards, the moving mechanism controls the moving seat to move the first clamping plate, the first mechanism, the second clamping plate, and the second mechanism upwards towards the discharge channel in the Z-axis direction. Then, the first mechanism controls the first clamping plate to move towards the second clamping plate, and the second mechanism controls the second clamping plate to move towards the first clamping plate. This causes the first and second clamping plates to clamp one end of the flat label plate moving downwards through the discharge channel. Since the second rubber roller is located above the support plate and rotatably supported on the material base, and the second rubber roller moves towards the support plate, the outer circumferential surface of the second rubber roller presses against the flat label plate on the support plate. At the other end of the label plate, the first and second clamping plates hold one end of the flat label plate on the support plate, and the outer circumferential surface of the second adhesive roller presses against the other end of the flat label plate on the support plate, so that the release paper of the flat label plate is firmly supported on the support plate, thereby preventing the release paper from loosening during the peeling of the flat label from the release paper. Then, the transfer mechanism of the adsorption device controls the adsorption plate to move directly above the support plate, so that the multiple suction nozzles of the adsorption plate adsorb the multiple flat labels of the flat label plate supported on the support plate, and then, along with the transfer... The carrier mechanism controls the adsorption plate to move multiple flat labels away from the release paper supported on the support plate. Simultaneously, the moving mechanism controls the moving seat to move the first clamping plate, the first mechanism, the second clamping plate, the second mechanism, and one end of the release paper downward in the Z-axis direction away from the discharge channel. The feeding mechanism controls the rotation of multiple first rubber rollers near the discharge port, and the second rubber roller rotates on its own. This allows multiple flat labels to be smoothly and quickly peeled off from the release paper firmly fixed on the support plate. Then, the transfer mechanism of the adsorption device controls the adsorption plate to move multiple flat labels onto the product or product packaging for automated labeling.

[0009] Therefore, the labeling machine of this invention can efficiently and automatically complete the label feeding, peeling and labeling operations with high precision and good stability, thereby improving the accuracy, stability and reliability of the operation, and thus improving the quality of operation and production efficiency.

[0010] A further embodiment includes a third rubber roller and a rotating mechanism. The third rubber roller is located directly below the second rubber roller and is rotatably supported on the material seat. The rotating mechanism controls the rotation of the third rubber roller. The outer circumferential surface of the third rubber roller has multiple third annular grooves at equal intervals in the Y-axis direction. The outer circumferential surface of the second rubber roller has multiple second annular grooves at equal intervals in the Y-axis direction. One second annular groove and one third annular groove are correspondingly arranged in the Z-axis direction. The feed end of the support plate has multiple clearance grooves at equal intervals in the Y-axis direction. A support arm is formed between two adjacent clearance grooves. One support arm and one third annular groove are correspondingly arranged in the Z-axis direction, so that a clamping channel is formed between the outer circumferential surface of the third rubber roller and the outer circumferential surface of the second rubber roller.

[0011] A further embodiment is that the feeding device also includes a sliding seat and a spring. The material seat is provided with a groove that extends in the Z-axis direction. The sliding seat is slidably disposed in the groove in the Z-axis direction. The second rubber roller is rotatably supported on the sliding seat. The two ends of the spring press against the upper end plate of the material seat and the sliding seat.

[0012] A further option is that the positioning device includes multiple rubber wheels and a rotating mechanism. The multiple rubber wheels are divided into two groups of positioning components and rotate in the Y-axis direction, supporting both sides of the support plate. A material passage is formed between the outer circumferential surface of the rubber wheels and the support plate. The rotating mechanism controls the multiple rubber wheels to rotate synchronously.

[0013] A further embodiment is that the rotating mechanism includes a first motor, a synchronizing rod, two first driving wheels, two transmission wheels, multiple first driven wheels, two first synchronous belts, and two second synchronous belts. The synchronizing rod is rotatably supported on a support plate. The two first driving wheels are sleeved on both ends of the synchronizing rod in the Y-axis direction. The drive shaft of the first motor is connected to one end of the synchronizing rod. Each rubber wheel has a support rod protruding from its shaft center. The support rod is rotatably supported on the support plate. One first driven wheel is sleeved on a support rod. One first synchronous belt is sleeved between multiple first driven wheels of a set of positioning components. One transmission wheel is sleeved on a support rod located directly above the synchronizing rod. One second synchronous belt is sleeved between a transmission wheel and a first driving wheel.

[0014] A further embodiment is that the rotating mechanism also includes multiple first tensioning pulleys, one of which is located between two adjacent first driven pulleys and is rotatably supported on the support plate, and the first tensioning pulley is located on one side of the first synchronous belt in the Z-axis direction and presses against the first synchronous belt.

[0015] A further option is to set the upper end of the discharge port on the side away from the feed port in the X-axis direction as an inclined surface.

[0016] A further approach is to have multiple first annular grooves evenly spaced on the outer circumferential surface of the first rubber roller in the Y-axis direction.

[0017] A further embodiment is that the feeding mechanism includes a second motor, a second driving wheel, multiple second driven wheels, and a third synchronous belt. The second driving wheel is sleeved on a first rubber roller, and a second driven wheel is sleeved on a first rubber roller. The third synchronous belt is sleeved between the second driving wheel and the multiple second driven wheels. The drive shaft of the second motor is connected to the first rubber roller on which the second driving wheel is sleeved.

[0018] A further embodiment is that the feeding mechanism also includes multiple second tensioning rollers, one of which is located between two adjacent second driven rollers and is rotatably supported on the material seat, and the second tensioning roller is located on one side of the third synchronous belt in the Z-axis direction and presses against the third synchronous belt.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0037] See Figures 1 to 17 This embodiment discloses a labeling machine 10, including a feeding device 11, a positioning device 12, and an adsorption device 13. Specifically, in this embodiment, the Z-axis direction is a vertical direction perpendicular to the horizontal direction, and the X-axis direction and Y-axis direction are perpendicular to each other and are two of the horizontal directions.

[0038] In this embodiment, the feeding device 11 includes a material base 111, a feeding mechanism, and a plurality of first rubber rollers 112. The material base 111 is provided with a material cavity 1111. The material cavity 1111 has an opening (not shown) at the bottom of one side in the X-axis direction. The plurality of first rubber rollers 112 are arranged side by side in the X-axis direction and are rotatably supported on the bottom of the material cavity 1111. The feeding mechanism controls the rotation of the plurality of first rubber rollers 112 near the opening.

[0039] Furthermore, in this embodiment, the positioning device 12 is located on one side of the opening of the material cavity 1111 in the X-axis direction, and the positioning device 12 includes a support plate 121, a movable seat 1241, a moving mechanism 1242, a first clamping plate 1243, a first mechanism 1244, a second clamping plate 1245, and a second mechanism 1246. The feeding end 1211 of the support plate 121 is inserted into the opening and forms a feeding port 1113 with the opening. The peeling end of the support plate 121 has a discharge port (not shown), and the support plate 121 has a guide rail 123 above its peeling end. The lower end face 1231 of the guide rail 123 is bent downwards in an arc shape and extends with the discharge port to form an arc shape. The discharge channel 122 extends downward in an arc shape. The movable seat 1241 is located below the discharge channel 122. The moving mechanism 1242 controls the movable seat 1241 to move in the Z-axis direction. The first mechanism 1244 is set on the movable seat 1241 and controls the first clamping plate 1243 to move toward or away from the second clamping plate 1245. The second mechanism 1246 is set on the movable seat 1241 and controls the second clamping plate 1245 to move toward or away from the first clamping plate 1243. The adsorption device 13 includes a transfer mechanism 132 and an adsorption plate 131. The transfer mechanism 132 controls the adsorption plate 131 to move. The lower end face of the adsorption plate 131 is provided with multiple suction nozzles 1311.

[0040] Furthermore, the feeding device 11 in this embodiment also includes a second rubber roller 114, a suction cup 116, and a lifting mechanism 1161. The suction cup 116 is located at the bottom of the material cavity 1111 and is arranged near the feeding port 1113. The lifting mechanism 1161 controls the suction cup 116 to move in the Z-axis direction. The second rubber roller 114 is located above the support plate 121 and is rotatably supported on the material seat 111. The second rubber roller 114 moves toward the support plate 121.

[0041] Therefore, in this embodiment, during operation, the labeling machine 10 places a stack of flat label sheets 20 into the material cavity 1111 of the material seat 111 of the feeding device 11. Multiple first adhesive rollers 112, located at the bottom of the material cavity 1111 and arranged side-by-side in the X-axis direction, stably support the stack of flat label sheets 20 within the material cavity 1111. When it is necessary to feed and label the bottommost flat label sheet 20 of the stack, the lifting mechanism 1161 of the feeding device 11 controls the suction cup 116 to move upwards in the Z-axis direction towards the bottommost flat label sheet 20 to adsorb the end of the bottommost flat label sheet 20 near the feeding port 1113. Then, the lifting mechanism 1161 controls the suction cup 116 to move downwards in the Z-axis direction towards the end of the bottommost flat label sheet 20 near the feeding port 1113 until it is flush with the feeding port 1113. In this embodiment, the feeding port 1113... 113 is the feeding end 1211 of the support plate 121, which is inserted into the opening and forms a gap with the opening. Then, the feeding mechanism controls the rotation of multiple first rubber rollers 112 near the feeding port 1113. At the same time, the suction cup 116 releases the bottom flat label 20 near the feeding port 1113, and the lifting mechanism 1161 controls the suction cup 116 to move away from the bottom flat label 20 in the Z-axis direction. This allows the bottom flat label 20 to be accurately fed into the feeding port 1113 in the X-axis direction, avoiding misalignment between the bottom flat label 20 and the feeding port 1113, which would cause the bottom flat label 20 to be blocked and wrinkled. This ensures that the bottom flat label 20 in the material cavity 1111 is accurately and stably fed to the feeding port 1113 and the support plate 121 of the positioning device 12.

[0042] As the feeding mechanism controls the rotation of multiple first rubber rollers 112 near the feeding port 1113, the flat label plate 20 at the bottom of the material cavity 1111 continues to move toward the peeling end of the support plate 121 in the X-axis direction. Since the peeling end of the support plate 121 in this embodiment has a discharge port, and the support plate 121 has a guide rail 123 above its peeling end, with the lower end face 1231 of the guide rail 123 curving downwards in an arc shape to form a downwardly curved discharge channel 122 with the discharge port, one end of the flat label plate 20 moving to the peeling end of the support plate 121 smoothly passes through the discharge channel 122 and moves downwards under the guidance of the downwardly curved discharge channel 122. The moving mechanism 1242 controls the moving seat 1241 to drive the first clamping plate 1243, the first mechanism 1244, the second clamping plate 1245, and the second mechanism 1246 to move upward toward the discharge channel 122 in the Z-axis direction. Subsequently, the first mechanism 1244 controls the first clamping plate 1243 to move toward the second clamping plate 1245, and the second mechanism 1246 controls the second clamping plate 1245 to move toward the first clamping plate 1243, so that the first clamping plate 1243 and the second clamping plate 1245 clamp one end of the flat label plate 20 moving downward through the discharge channel 122. Since in this embodiment the second glue roller 114 is located above the support plate 121 and is rotatably supported on the material seat 111, and the second glue roller 114 moves toward the support plate 121, The outer peripheral surface of the second roller 114 presses against the other end of the flat label plate 20 on the support plate 121. The first clamping plate 1243 and the second clamping plate 1245 clamp one end of the flat label plate 20 on the support plate 121, while the outer peripheral surface of the second roller 114 presses against the other end of the flat label plate 20 on the support plate 121. This ensures that the release paper 21 of the flat label plate 20 is firmly supported on the support plate 121, preventing the release paper 21 from loosening during the peeling of the flat label 22 from the release paper 21. Then, the transfer mechanism 132 of the adsorption device 13 controls the adsorption plate 131 to move directly above the support plate 121, so that the multiple suction nozzles 1311 of the adsorption plate 131... Multiple flat labels 22 supported on the flat label plate 20 are adsorbed. Then, the transfer mechanism 132 controls the adsorption plate 131 to move the multiple flat labels 22 away from the release paper 21 supported on the support plate 121. Simultaneously, the moving mechanism 1242 controls the moving seat 1241 to move the first clamping plate 1243, the first mechanism 1244, the second clamping plate 1245, the second mechanism 1246, and one end of the release paper 21 downward in the Z-axis direction away from the discharge channel 122. At the same time, the feeding mechanism controls the multiple first rubber rollers 112 near the discharge port to rotate, and the second rubber roller 114 rotates, so that the multiple flat labels 22 can be smoothly and quickly peeled off from the release paper 21 firmly supported on the support plate 121.Then, the transfer mechanism 132 of the adsorption device 13 controls the adsorption plate 131 to move multiple flat labels 22 onto the product or product packaging for automated labeling.

[0043] Therefore, the labeling machine 10 in this embodiment can efficiently and automatically complete the label feeding, peeling, and labeling operations with high precision and good stability, thereby improving the accuracy, stability, and reliability of the operation, and thus improving the quality of operation and production efficiency.

[0044] Combination Figures 3 to 9 In this embodiment, the feeding device 11 further includes a third rubber roller 115 and a rotating mechanism 1152. The third rubber roller 115 is located directly below the second rubber roller 114 and is rotatably supported on the material base 111. The rotating mechanism 1152 controls the rotation of the third rubber roller 115. Furthermore, the outer circumferential surface of the third rubber roller 115 has multiple third annular grooves 1151 evenly spaced in the Y-axis direction. The outer circumferential surface of the second rubber roller 114 has multiple second annular grooves 1141 evenly spaced in the Y-axis direction. One second annular groove 1141 corresponds to one third annular groove 1151 in the Z-axis direction. The feeding end 1211 of the support plate 121 has multiple third annular grooves 1151 evenly spaced in the Y-axis direction. Multiple clearance grooves 1212 are provided, and a support arm (not shown) is formed between two adjacent clearance grooves 1212. One support arm and a third annular groove 1151 are correspondingly arranged in the Z-axis direction, so that a clamping channel is formed between the outer peripheral surface of the third rubber roller 115 and the outer peripheral surface of the second rubber roller 114. Thus, the flat label plate 20 passing through the feed port 1113 is elastically clamped by the clamping channel formed between the outer peripheral surface of the third rubber roller 115 and the outer peripheral surface of the second rubber roller 114, further improving the stability of the flat label plate 20 on the support plate 121 to achieve stable feeding, and further improving the accuracy, stability and reliability of labeling. Furthermore, in this embodiment, the outer peripheral surface of the third rubber roller 115 is provided with a plurality of third annular grooves 1151 at equal intervals in the Y-axis direction, and the outer peripheral surface of the second rubber roller 114 is provided with a plurality of second annular grooves 1141 at equal intervals in the Y-axis direction. One second annular groove 1141 and one third annular groove 1151 are correspondingly arranged in the Z-axis direction, thereby reducing the area of ​​the clamping channel formed between the outer peripheral surface of the third rubber roller 115 and the outer peripheral surface of the second rubber roller 114 for elastic clamping of the flat label plate 20, thereby reducing the elastic clamping friction of the clamping channel formed between the outer peripheral surface of the third rubber roller 115 and the outer peripheral surface of the second rubber roller 114 for the flat label plate 20, and avoiding excessive friction that would affect the smooth and stable feeding of the flat label plate 20.

[0045] In order to further improve the smoothness and stability of feeding the flat label plate 20, in this embodiment, the outer peripheral surface of the first rubber roller 112 is provided with a plurality of first annular grooves 1121 at equal intervals in the Y-axis direction to reduce feeding friction.

[0046] To improve the stability and reliability of the feeding control, the feeding mechanism in this embodiment includes a second motor 1131, a second drive wheel 1132, a plurality of second driven wheels 1133, and a third synchronous belt 1134. The second drive wheel 1132 is sleeved on a first rubber roller 112, and a second driven wheel 1133 is sleeved on a first rubber roller 112. The third synchronous belt 1134 is sleeved between the second drive wheel 1132 and the plurality of second driven wheels 1133. The drive shaft of the second motor 1131 is connected to the first rubber roller 112 on which the second drive wheel 1132 is sleeved. Specifically, the feeding mechanism in this embodiment also includes a plurality of second tensioning rollers 1135. One second tensioning roller 1135 is located between two adjacent second driven rollers 1133 and is rotatably supported on the material seat 111. The second tensioning roller 1135 is located on one side of the third synchronous belt 1134 in the Z-axis direction and presses against the third synchronous belt 1134 to adjust the tension of the third synchronous belt 1134, thereby improving the working reliability and stability of the third synchronous belt 1134.

[0047] Specifically, the feeding device 11 in this embodiment further includes a sliding seat 1143 and a spring 1142. The material seat 111 is provided with a groove 1114, which extends in the Z-axis direction. The sliding seat 1143 is slidably disposed in the groove 1114 in the Z-axis direction. The second rubber roller 114 is rotatably supported on the sliding seat 1143. The two ends of the spring 1142 press against the upper end plate 1112 of the material seat 111 and the sliding seat 1143, thereby elastically forcing the second rubber roller 114 to move toward the support plate 121.

[0048] Combination Figures 10 to 15 In this embodiment, the positioning device 12 includes multiple rubber wheels 125 and a rotating mechanism. The multiple rubber wheels 125 are divided into two groups of positioning components and are rotatably supported on both sides of the support plate 121 in the Y-axis direction. A material passage is formed between the outer peripheral surface of the rubber wheels 125 and the support plate 121. The rotating mechanism controls the multiple rubber wheels 125 to rotate synchronously, so that the two ends of the release paper 21 of the flat label plate 20 in the Y-axis direction pass through the material passage formed between the outer peripheral surface of the rubber wheels 125 and the support plate 121. This ensures that the two ends of the release paper 21 of the flat label plate 20 in the Y-axis direction are firmly restricted to the support plate 121 by the rubber wheels 125, thereby preventing the release paper 21 from loosening during the peeling of the flat label 22 from the release paper 21.

[0049] To improve the working stability and reliability of the rubber wheel 125, the rotating mechanism in this embodiment includes a first motor 1261, a synchronizing rod 1262, two first driving wheels 1263, two transmission wheels 1264, multiple first driven wheels 1266, two first synchronous belts 1267, and two second synchronous belts 1265. The synchronizing rod 1262 is rotatably supported on the support plate 121. The two first driving wheels 1263 are sleeved on both ends of the synchronizing rod 1262 in the Y-axis direction. The drive shaft of the first motor 1261 is aligned with one end of the synchronizing rod 1262. Each rubber wheel 125 has a support rod 1251 protruding from its shaft. The support rod 1251 is rotatably supported on the support plate 121. A first driven wheel 1266 is sleeved on a support rod 1251. A first synchronous belt 1267 is sleeved between multiple first driven wheels 1266 of a set of positioning components. A transmission wheel 1264 is sleeved on a support rod 1251 located directly above the synchronous rod 1262. A second synchronous belt 1265 is sleeved between a transmission wheel 1264 and a first driving wheel 1263.
