[0010] The transfer and turning mechanism includes a linear transfer mechanism and a first label suction mechanism turning control guide rail. The first label suction mechanism is transferred by the linear transfer mechanism and is guided to turn by the turning control guide rail. In the transfer direction from the label outlet to the position where it intersects with the second label suction mechanism of the second label transfer mechanism, the first label suction mechanism turns from facing the label outlet to facing away from it, and turns from facing away from the label outlet to facing the label outlet when returning.

[0011] The first label suction mechanism is provided with a first suction structure for the label portion attached to the bottom of the cup and a second suction structure for the label portion attached to the side of the cup.

[0013] The label placing device is provided with a label transfer suction structure for transferring the label part attached to the side of the cup adsorbed by the first label suction mechanism to the fourth suction structure adsorbed by the second label suction mechanism. The label transfer suction structures correspond to the first label suction mechanisms one by one.

[0018] The movable frame can be connected to the lifting mechanism and the guide mechanism for controlling its rotation, so that it can rotate during the vertical lifting process. The transfer direction from the position intersecting with the first label suction mechanism to the position intersecting with the third label suction mechanism of the third label transfer mechanism is to turn the second label suction mechanism from an inclined position to a horizontal upward position during the ascending process, and in the return process, to turn the second label suction mechanism from a horizontal upward position to an inclined state that can intersect with the first label suction mechanism during the descending process; a spacing scaling mechanism is set in the movable frame, and the second label suction mechanism is connected to the spacing scaling mechanism. Alternatively, the movable frame can be driven to rotate and lift by a rotating arm.

[0019] The multiple second label suction mechanisms are arranged in multiple rows and columns; the spacing scaling mechanism includes an X-axis and a Y-axis, and the second label suction mechanisms in each row that need to be adjusted in the multiple second label transfer mechanisms are movably connected to the same X-axis, and the second label suction mechanisms in each column that need to be adjusted in the position are movably connected to the same Y-axis.

[0020] Furthermore, a first guide rail for the X-axis to move in the Y-axis and a second guide rail for the Y-axis to move in the X-axis are also provided on the movable frame.

[0022] Further, the driving mechanism in the pitch scaling mechanism adopts a synchronous belt conveying mechanism, and a guide groove inclined to the X-direction is provided for the second label sucking mechanism at the corner; the driving mechanism is also provided with a limiting structure; the second label sucking mechanism at the corner is provided with a guide member slidably connected to its guide groove; when the number of X-axes is two, they are symmetrically connected to the upper synchronous belt and the lower synchronous belt of this synchronous belt in the Y-direction; when the number of X-axes is three, the two X-axes that need to be adjusted in position are symmetrically connected to the upper synchronous belt and the lower synchronous belt of this synchronous belt in the Y-direction; when the number of X-axes is more than three, the X-axes at the frontmost and rearmost sides in the Y-direction are symmetrically connected to the upper synchronous belt and the lower synchronous belt of this synchronous belt in the Y-direction, and the remaining X-axes that need to be adjusted in position are moved and spaced by the cooperation of the Y-direction limiting mechanism; when the number of Y-axes is two or three, the Y-axes that need to be adjusted in position are moved and spaced by the movement of the X-axis and the cooperation of the guide groove and the guide member; when the number of Y-axes is more than four, the Y-axes at the frontmost and rearmost sides in the X-direction are moved by the movement of the X-axis and the cooperation of the guide groove and the guide member; the remaining Y-axes that need to be adjusted in position are moved and spaced by the cooperation of the X-direction limiting mechanism.

[0023] Further, the driving mechanism in the spacing scaling mechanism adopts an X-direction synchronous belt conveying mechanism and a Y-direction synchronous belt conveying mechanism, and the driving mechanism is also provided with a limiting structure; when there are two X-direction sliding shafts, they are symmetrically connected in the Y direction to the upper synchronous belt and the lower synchronous belt of the Y-direction synchronous belt; when there are three X-direction shafts, the two X-direction shafts that need to be adjusted in position are symmetrically connected in the Y direction to the upper synchronous belt and the lower synchronous belt of the Y-direction synchronous belt; when there are more than three X-direction shafts, the X-direction sliding shafts at the frontmost and rearmost sides in the Y direction are symmetrically connected in the Y direction to the upper synchronous belt and the lower synchronous belt of the Y-direction synchronous belt, and the remaining X-direction shafts that need to be adjusted in position are moved and spaced by the cooperation of the Y-direction limiting mechanism; when there are two Y-direction shafts, they are symmetrically connected in the X direction to the upper synchronous belt and the lower synchronous belt of the X-direction synchronous belt; when there are three Y-direction shafts, the two Y-direction shafts that need to be adjusted in position are symmetrically connected in the X direction to the synchronous belt on one side and the synchronous belt on the other side of the X-direction synchronous belt; when there are more than three Y-direction shafts, the Y-direction shafts at the frontmost and rearmost sides in the X direction are symmetrically connected in the X direction to the synchronous belt on one side and the synchronous belt on the other side of the X-direction synchronous belt, and the remaining Y-direction shafts that need to be adjusted in position are moved and spaced by the cooperation of the X-direction limiting mechanism.

Still further, the distance reduction limiting structure includes a top member and a blocking member respectively connected to adjacent shafts; the distance increase limiting mechanism includes a tube respectively connected to adjacent shafts and a hole sleeved outside the tube, and the hole sleeved outside the tube limits the pulling-out length of the tube.

[0025] The top air suction structure of the convex configuration of the third label suction mechanism or the third air suction structure of the second label suction mechanism is a telescopic elastic air suction structure.

[0026] Another technical problem to be solved by the present invention is to provide a label placing method, which can simplify the corresponding mechanical device, improve efficiency and accuracy, and improve the utilization rate of the plastic film of the formed container. For this purpose, the present invention adopts the following technical solutions:

[0027] A label placing method, characterized in that:

[0028] It places several stacks of labels on several label storage positions respectively;

[0029] A number of first label suction mechanisms, which are actively installed on the moving rack corresponding to the number of label storage positions, respectively suck the forward-facing side of the labels at the front of each label storage position; the moving rack is moved to the first label handover position, and during the movement, the first label suction mechanism turns around under the guidance of the guide rail.

[0030] At the first label handover position, the labels adsorbed by the first label suction mechanism are handed over to be adsorbed by the second label suction mechanism.

[0031] The second label suction mechanism is moved by its transfer and spacing scaling mechanism to the second label handover position. During the transfer process, the arrangement position of the second label suction mechanism changes from corresponding to the first label suction mechanism with a reduced spacing to corresponding to the third label suction mechanism.

[0032] At the second label handover position, the convex configurations of the third label suction mechanisms corresponding one by one to the second label suction mechanisms receive the labels. The arrangement mode of the convex configurations of the third label suction mechanisms is the same as the arrangement mode of the cup molds of the cup-making molds. The labels are adsorbed by the convex configurations with the air suction function and then are moved to the cup-making molds, and the convex configurations match the cup molds.

[0033] The convex configurations are inserted into the cup molds to hand over the labels to the cup molds of the cup-making molds.

[0034] On the basis of adopting the above technical solutions, the present invention can also adopt the following further technical solutions or use a combination of these further technical solutions:

[0035] The first label suction mechanism turns around under the guidance of the guide rail.

[0036] The directions of the label stacking storage positions and the label outlet are obliquely downward, and the direction in which the moving rack is moved to the first label handover position is also obliquely downward with the same slope; the transfer direction of the transfer and spacing scaling mechanism of the second label suction mechanism from the position of handing over with the first label suction mechanism to the position of handing over with the third label suction mechanism of the third label transfer mechanism is: changing the second label mechanism from an inclined state to horizontally upward, and lifting the second label mechanism.

[0037] After the second label mechanism changes from an inclined state to horizontally upward, the second label mechanism is further vertically lifted.

[0038] The label includes a label part attached to the side of the cup and a label part attached to the bottom of the cup, and the label part attached to the side of the cup and the label part attached to the bottom of the cup are connected; when the first label sucking mechanism sucks the label, it sucks the label part attached to the side of the cup, or also sucks the label part attached to the bottom of the cup; when the second label sucking mechanism receives the label, its third air suction structure adsorbs the label part attached to the bottom of the cup, and the fourth air suction structure adsorbs the label part attached to the side of the cup; the top air suction structure on the convex configuration of the third label sucking mechanism adsorbs the label part attached to the bottom of the cup, and the side air suction structure on the convex configuration adsorbs the label part attached to the side of the cup.

[0039] The label includes a label part attached to the side of the cup and a label part attached to the bottom of the cup, and the label part attached to the side of the cup and the label part attached to the bottom of the cup are separate; the first air suction structure of the first label sucking mechanism sucks the label part attached to the bottom of the cup, and the second air suction structure of the first label sucking mechanism sucks the label part attached to the side of the cup; when the first label sucking mechanism transfers the label to the second label sucking mechanism, the third air suction structure of the second label sucking mechanism directly sucks the label part attached to the bottom of the cup, and the label part attached to the side of the cup is transferred by the transfer label sucking structure. The transfer label sucking structure sucks the label part attached to the side of the cup, and then rotates upward or downward to make the label part attached to the side of the cup face upward or downward and be within the adsorption range of the fourth air suction structure of the second label sucking mechanism. The fourth air suction structure sucks the lower part of the label part attached to the side of the cup, and the lower part of the label part attached to the side of the cup surrounds the fourth air suction structure; the top air suction structure of the convex configuration of the third label sucking mechanism is a telescopic air suction structure. When the second label sucking mechanism transfers the label to the third label sucking mechanism, the top air suction structure of the convex configuration in the third label sucking mechanism adsorbs the label part attached to the bottom of the cup, and the side air suction structure on the convex configuration adsorbs the upper part of the label part attached to the side of the cup and is on the same side as the fourth air suction structure that adsorbs the label. The upper part of the label part attached to the side of the cup surrounds the side air suction structure, and, after the third label sucking mechanism and the second label sucking mechanism are separated, the top air suction structure pops out.

[0040] Due to the adoption of the technical solution of the present invention, the entire process action route of the present invention is naturally connected, the overall machine efficiency is high, the speed is fast, and the mold spacing for preparing the container can be minimized, improving the utilization rate of raw materials.

[0060] Referring to the accompanying drawings, a label placing device provided by the present invention comprises a label storage mechanism, a first label transfer mechanism, a second label transfer mechanism and a third label transfer mechanism.

[0061] The label storage mechanism is provided with a plurality of label stacking and storage positions and corresponding label outlets corresponding to the cup molds 501 on the cup-making mold 500, and the label stacking and storage positions correspond to the cup molds 501 of the cup-making mold 500. The label stacking and storage positions can be a channel formed by a rack 11, and the rack 11 is installed on the mounting plate 1 of the label storage mechanism, and the mounting plate 1 has a hole at the end of the channel as a label outlet 12.

[0062] The direction of the label stack storage position formed by the rack 11, which is also the channel direction, and the direction of the label outlet 12 are obliquely downward, and the vertically placed label stack can automatically move toward the label outlet by gravity after the frontmost label is taken away.

[0063] The label 600 includes a label portion 602 attached to the side of the cup or further includes a label portion 601 attached to the bottom of the cup. The label portion 602 attached to the side of the cup and the label portion 601 attached to the bottom of the cup can be connected (for example, Figure 10 As shown), it can also be split (for example, Figure 11 As shown in the figure). For the former, the original unfolded shape may be a cross, the intersection of the cross is the label part 601 attached to the bottom of the cup, and the bifurcation of the cross is the label part 602 attached to the side of the cup. For the latter, the original unfolded shape of the label part 602 attached to the side of the cup may be an arc or other curved shape. The device of the present invention is also applicable to labels with only the label part attached to the side of the cup.

[0064] The first label transfer mechanism is arranged obliquely below the label storage mechanism. If the direction of the label stacking and storage position and the direction of the label outlet 12 are horizontal, the first label transfer mechanism can also be arranged at a height that matches them.

[0065] Figures 1-9An application is shown in which the label portion 602 attached to the side of the cup and the label portion 601 attached to the bottom of the cup are connected (for example, Figure 10 A marking device as shown).

[0066] The first label transfer mechanism is provided with first label suction mechanisms whose number and arrangement positions correspond to the label outlets one by one. The first label suction mechanism is provided with a first suction structure 21 for the label part 601 attached to the bottom of the cup, which can be a retractable suction structure driven by a cylinder. The first label transfer mechanism is also provided with a transfer and turning mechanism of the first label suction mechanism, so that the first label suction mechanism can travel between the label outlet 12 and the position where the second label suction mechanism of the second label transfer mechanism delivers labels. At the position where the labels are delivered, the first suction structure 21 can extend into the second label suction mechanism.

[0067] The label portion 602 attached to the side of the cup is connected to the label portion 601 attached to the bottom of the cup (for example, Figure 10 The first label suction mechanism is also provided with a second suction structure, which includes a suction structure around the first suction structure 21, such as a plurality of suction cups 22. The plurality of suction cups 22 are respectively used to suck the cross-shaped bifurcation.

[0068] Alternatively, if the label is not in the shape of a cross, the second suction structure can suck the label part 602 of other shapes attached to the side of the cup. In addition, if the label part 601 attached to the bottom of the cup and the label part 602 attached to the side of the cup are connected, the first label suction mechanism may not be provided with the first suction structure 21; if only the label part attached to the side of the cup is used, the first label suction mechanism may not be provided with the first suction structure 21.

[0069] The transfer and turning mechanism includes a linear transfer mechanism and a first label suction mechanism turning control guide rail 23. The first label suction mechanism is transported by the linear transfer mechanism, and the linear transfer mechanism includes a motor 241 as a power, a linear guide rail 242, and a moving frame 243. The motor 241 and the linear guide rail 242 are arranged on both sides of the moving frame 243. The motor 241 is connected to the moving frame 243 through a gear rack structure or a ball screw pair and other structures. The moving frame 243 is also slidably connected to the linear guide rail 242, and the moving frame 243 can also be driven by a cylinder. In this way, the above-mentioned linear transfer action can be fully utilized, and the turning and reversing can be completed without separately configuring a power drive during the movement. In addition, the linear transfer action and the corresponding structure also bring greater freedom to the arrangement of the second label transfer mechanism described below.

[0070] When the direction of the label stacking storage position and the label outlet 12 is obliquely downward, the linear guide rail 242 is also inclined with the same slope. The transfer direction of the first label suction mechanism from the label outlet to the position where the label is transferred to the second label suction mechanism of the second label transfer mechanism is also obliquely downward with the same slope, and the return journey is obliquely upward with the same slope.

[0071] When the first label suction mechanism is transferred by the linear transfer mechanism, it is guided by the guide rail 23. In the transfer direction from the label outlet 12 to the position where the label is transferred to the second label suction mechanism of the second label transfer mechanism, the first label suction mechanism turns from facing the label outlet to facing away from it, and turns from facing away from the label outlet to facing the label outlet during the return journey.

[0072] The turning control guide rail 23 controls the label suction mechanism to turn in one turning direction when being linearly conveyed forward, and turn back in the opposite turning direction when being linearly conveyed back. The guide rail 23 is located below the moving frame 243. The guide rail 23 can be symmetrically inclined or symmetrically curved with respect to the midpoint. The first label suction mechanism can be installed on the rotating frame 25, and the rotating frame 25 is then rotationally connected to the moving frame 243 through the bearing 27. A connecting rod 26 is fixedly connected to the bottom of the rotating frame 25, and the connecting rod 26 is slidably connected to the guide rail 23 through the roller 261. Under the control and drive of the guide rail 23, the rotating frame 25 is driven to rotate and the first label suction mechanism turns.

[0073] As another implementation manner, the first label suction mechanism can also be controlled and driven to turn by directly driving the rotating frame 25 to rotate by a motor.

[0074] The rotation axis of the turning is generally perpendicular to the direction of the linear transfer, and can also be inclined at a certain angle.

[0075] When the first label suction mechanism moves to the position where the label is transferred to the second label suction mechanism of the second label transfer mechanism, the retractable first suction structure 21 ejects. For the label with a cross-shaped unfolded shape, it ejects the cross intersection, that is, the label part 601 pasted on the bottom of the cup, so that the label enters the second label suction mechanism in a convex shape with natural transition and is within its suction range.

[0076] The second label transfer mechanism is provided with a second label suction mechanism corresponding to the first label suction mechanism. The second label suction mechanism is provided with a third suction structure 311 for the label part 601 attached to the bottom of the cup and a fourth suction structure 312 for the label part 602 attached to the side of the cup. In the second label suction mechanism, the third suction structure 311 is in the middle, and the reference numeral 315 is its suction port. The fourth suction structure 312 includes a plurality of suction ports 313 around the third suction structure and facing the inside. The third suction structure 311 can be a retractable suction structure supported by a spring 314, which is pressed down when the first suction structure 21 extends into the second label suction mechanism. In this way, it can closely connect the label with the first label suction mechanism and the third label suction mechanism and improve the sensitivity when it is separated from the third label suction mechanism, thereby improving the positioning quality of the label. The spring can also be replaced by a retractable mechanism or other elastic components.

[0077] When the first label suction mechanism and the second label suction mechanism hand over the label, the third air suction structure 311 and the fourth air suction structure 312 suction air to hold the delivered label, wherein the label part 601 is sucked onto the third air suction structure 311, and the label part 602 is sucked onto the fourth air suction structure 312, wherein the third air suction structure 311 is pressed down when the first air suction structure 21 extends into the second label suction mechanism, and pops out again after the first air suction structure 21 leaves.

[0078] When the first label suction mechanism and the second label suction mechanism hand over labels, in addition to the above-mentioned direct handover of labels, the label handover can also be performed with the help of the handover label suction structure.

[0079] The second label transfer mechanism is provided with a transfer and spacing scaling mechanism of the second label suction mechanism, so that the second label suction mechanism can move between a position intersecting with the first label suction mechanism and a position intersecting with the third label suction mechanism of the third label transfer mechanism, and its arrangement position changes from corresponding to the first label suction mechanism to corresponding to the third label suction mechanism; in this way, the various cup molds 501 of the cup making mold 500 can be arranged closely, reducing the waste edges of the cup making membrane.

[0080] The transfer and spacing scaling mechanism of the second label suction mechanism includes a movable frame 32, and the second label suction mechanism is installed in the movable frame 32. The movable frame 32 is connected to the lifting mechanism 33 and is also connected to a guide mechanism that controls its rotation, so that it can also rotate during the vertical lifting process. The transfer direction from the position intersecting with the first label suction mechanism to the position intersecting with the third label suction mechanism of the third label transfer mechanism is to turn the second label suction mechanism from inclined to horizontal upward during the ascending process, and in the return process, the second label suction mechanism is turned from horizontal upward to an inclined state that can be intersected with the first label suction mechanism during the descending process.

[0081] The guiding mechanism, i.e., the following guide rail 34, can be provided with a vertical guiding structure 341 after the second label sucking mechanism turns horizontally upward, so that the second label sucking mechanism can be vertically lifted after turning from the inclined state to the horizontal upward state. In this way, for the third label transferring mechanism, a lifting mechanism may not necessarily be provided, which helps to simplify the structure and improve the overall machine speed. The guiding before this guiding mechanism can be carried out synchronously with rotation and lifting, or step by step with lifting and rotation.

[0082] The lifting mechanism 33 can adopt a chain or synchronous belt conveying structure and be equipped with a lifting guide rail 331, or can also adopt a linear conveying structure driven by a cylinder. The lifting mechanism 33 and the lifting guide rail 331 are both installed on the fixed frame 3 of the second label transferring mechanism. A guide rail 34 for controlling the rotation of the movable frame 32 is also provided on the fixed frame 3 as the guiding mechanism for controlling the rotation of the movable frame (alternatively, the movable frame can be flipped by a cylinder drive or a motor drive). The movable frame 32 is connected to a component 321 connected to the slider substrate 350. The slider 35 is arranged on the slider substrate 350. The slider substrate 350 is connected to a connecting component 332 on the lifting mechanism 33. The slider 35 is slidably connected to the lifting guide rail 331. The movable frame 32 is also fixedly connected to a component 36 connected to the guide rail 34 for controlling the rotation of the movable frame 32. This component 36 can be a connecting rod, and a roller 361 cooperating with the guide rail 34 is arranged at the end of the connecting rod.

[0083] A pitch scaling mechanism is arranged in the movable frame 32. The second label sucking mechanism is connected to the pitch scaling mechanism and is movably installed in the movable frame 32 through the pitch scaling mechanism. From the label receiving position (the position where the label is transferred with the first label sucking mechanism) to the label transferring position (the position where the label is transferred with the third label sucking mechanism), the arrangement pitch of the several label sucking mechanisms is reduced. From the label transferring position to the label receiving position, the arrangement pitch of the several label sucking mechanisms is enlarged.

[0084] The pitch scaling mechanism includes an X-direction axis 372 and a Y-direction axis 373. Each row of the second label sucking mechanisms whose positions need to be adjusted in the several label transferring mechanisms is movably connected to the same X-direction axis 372, and each column of the second label sucking mechanisms whose positions need to be adjusted is movably connected to the same Y-direction axis 373.

[0085] A first guide rail 381 for the X-direction axis 372 to move in the Y direction and a second guide rail 382 for the Y-direction axis 373 to move in the X direction are also arranged on the movable frame. The X-direction axis and the Y-direction axis are connected to corresponding sliders 375, 376 and are slidably connected to the first guide rail 381 and the second guide rail 382. The pitch scaling mechanism is provided with a driving mechanism for moving the position of the label sucking mechanism to scale the pitch.

[0086] In this embodiment, there are a total of 10 label sucking mechanisms, which are arranged in a 2-row and 5-column manner. A second label sucking mechanism is arranged at the intersection position of the X-axis 372 and the Y-axis 373; for the second label sucking mechanism whose position needs to be adjusted, a sliding member 370 is arranged at the intersection position, and the X-axis 372 and the Y-axis 373 respectively pass through the sliding member 370, and the sliding member 370 can slide along the Y-axis or / and the X-axis.

[0087] There are a total of 5 Y-axis 373s. The middle Y-axis is fixed, and the remaining four Y-axis 373s that need to adjust their positions are symmetrically distributed on both sides of the middle Y-axis.

[0088] For this embodiment, the driving mechanism in the pitch scaling mechanism uses a Y-direction synchronous belt conveying mechanism to drive the X-axis and the Y-axis. The driving mechanism is provided with a guide groove 371 inclined to the X-direction for the second label sucking mechanism at the corner of these second label sucking mechanisms arranged in a matrix, and the driving mechanism is also provided with a limiting structure;

[0089] The label sucking mechanism at the corner is provided with a guiding component 374 slidably connected to its guide groove 371, and this guiding component can be arranged on the sliding member 370.

[0090] There are two X-axes, and they are symmetrically connected in the Y-direction to the upper synchronous belt 391 and the lower synchronous belt 392 of this synchronous belt. The reference numeral 390 in the attached drawing is the motor and transmission belt of the synchronous belt mechanism.

[0091] For the 5 Y-axes, the Y-axes at the frontmost and rearmost positions in the X-direction move through the movement of the X-axis and the cooperation of the guide groove 371 and the guiding component 374; the remaining Y-axes that need to adjust their positions move and are spaced by the cooperation of the X-direction limiting mechanism.

[0092] The movable frame 32 has a rectangular frame structure, and the guide groove 371 is arranged on the bottom plate of the movable frame 32.

[0093] For this 2-row and 5-column arrangement in this embodiment, the pitch scaling in the Y-direction can be determined by the synchronous belt mechanism, and the limiting mechanism can be only arranged in the X-direction. The limiting mechanism includes a pitch reduction limiting structure and a pitch increase limiting structure.

[0094] The distance reduction limiting structure includes a top member 3771 and a stop member 3772 respectively connected to adjacent shafts; the distance increase limiting mechanism includes a tube 3781 and a hole 3782 sleeved outside the tube, both of which are respectively connected to adjacent shafts. The length of the tube pulled out by the hole sleeved outside the tube is limited, so that during distance reduction, the top member 3771 on the previous shaft can achieve a fixed distance after contact by moving from a certain distance away to contacting the stop member 3772 on the subsequent shaft, and can push it during subsequent new contacts, and so on; when changing from distance reduction to distance increase, the limiting structure in the hole 3782 pulls the tube 3781 to achieve sequential separation. These limiting structures can be arranged on the slider 376 that is slidably connected to the second guide rail 382 on the sliding shaft 373 in the Y direction.

[0095] Referring to Figure 8a , in this embodiment, another implementation manner of the driving mechanism in the pitch scaling mechanism is provided. The driving mechanism in the pitch scaling mechanism adopts an X-direction synchronous belt conveying mechanism and a Y-direction synchronous belt conveying mechanism, and the driving mechanism is also provided with a limiting structure;

[0096] The Y-direction synchronous belt conveying mechanism is the same as the foregoing, and the same reference numerals are also used in Figure 8a . The implementation manner of the limiting mechanism is also the same as the foregoing.

[0097] When in the Y-direction shafts, the Y-direction shafts at the frontmost and rearmost sides in the X direction are symmetrically connected to the synchronous belt 393 on one side and the synchronous belt 394 on the other side of the X-direction synchronous belt in the X direction, and the remaining Y-direction shafts whose positions need to be adjusted move and are fixed in distance through the cooperation of the X-direction limiting mechanism. The reference numeral 395 is the motor of the X-direction synchronous belt mechanism.

[0098] The third label transfer mechanism is provided with a third label suction mechanism 41. The third label suction mechanism 41 has convex configurations 410 whose quantity and positions correspond one-to-one to the cup molds 501 of the cup-making mold. The third label suction mechanism is located above the second label transfer mechanism.

[0099] The convex configurations 410 can be inserted into the cup molds 501, and can also be inserted into the second label suction mechanism. The convex configurations are provided with a top suction structure 411 for the label part 601 pasted on the bottom of the cup and a side suction structure 412 for the label part 602 pasted on the side of the cup. The reference numeral 413 is the suction port of these suction structures, which can suck the supplied labels. Among them, the label part 601 is sucked on the top of the convex configuration, and the label part 602 is sucked on the surrounding side walls of the convex configuration. The shapes of the convex configurations 410 and the cup molds 501 match. After being transferred to above the cup-making mold 500 by its transfer mechanism, the mold 500 rises, and each convex configuration 410 is inserted into each cup mold 501 one by one to complete the label feeding work.

[0100] The third label transfer mechanism is provided with a transfer mechanism 42 of the third label suction mechanism, so that the third label suction mechanism can travel between the position intersecting with the second label suction mechanism and the position inserted into the cup mold. The mechanism can be a horizontal rotating device, so that the convex configuration of the third label suction mechanism can be aligned with the second label suction mechanism and the cup mold 501, and then the mold 500 rises, and each convex configuration 410 is inserted into each cup mold 501 one by one to complete the label delivery work. In this way, combined with the second label mechanism being vertically lifted after turning from an inclined state to a horizontal upward state, in the case of having multiple molds 500 to receive labels in turn and multiple third label suction mechanisms, not only the third label transfer mechanism can be provided without a lifting device, but also the efficiency of the whole machine is higher.

[0101] According to needs, a lifting device can also be provided on the horizontal rotating device to be able to lift and lower the third label suction mechanism.

[0102] The labeling method using the above labeling device is as follows:

[0103] A plurality of stacks of labels are placed in each label storage position, wherein the labels are placed with their reverse sides facing forward, that is, the reverse sides facing inwards after the labels are attached to the cups.

[0104] The first label suction mechanism movably mounted on the mobile frame suctions the front side of the front label of each label storage position respectively; the mobile frame is moved to the first label handover position, and during the movement, the first label suction mechanism turns around under the guidance of the turning control guide rail 23; at the first label handover position, the label sucked by the first label suction mechanism is transferred to the second label suction mechanism for suction.

[0105] The first label suction mechanism returns, and the second label suction mechanism is transferred and moved to the second label handover position by its transfer and spacing scaling mechanism. During the transfer process, the arrangement position of the second label suction mechanism changes from corresponding to the first label suction mechanism with a reduced spacing to corresponding to the third label suction mechanism. Since the first label suction mechanism returns, in addition to the movement mode of changing the second label suction mechanism from tilted to horizontal upward and the corresponding transfer mechanism during the rising process; the second label suction mechanism can also be lifted by circular motion and changed from tilted to horizontal upward, and after being turned horizontal, it can be lifted vertically for a distance; or the second label suction mechanism can be lifted while being driven by the transmission mechanism and changed from tilted to horizontal upward and other movement modes and corresponding transfer mechanisms, and after being turned horizontal, it can be lifted vertically for a distance, so that the second label suction mechanism and the convex configuration can perform label handover.

[0106] At the position of the second label sucking mechanism, the convex configuration 410 of the third label sucking mechanism corresponding to each second label sucking mechanism receives the label. The label is adsorbed by the convex configuration 410 with the air suction function and then transferred to the cup-making mold. The convex configuration 410 and the cup mold 501 are matched.

[0107] The convex configuration is inserted into the cup mold, and the label is handed over to the cup mold of the cup-making mold.

[0108] During the above process:

[0109] The first label sucking mechanism sucks the reverse side of the label. Among them, the first air suction structure 21 sucks the label part 601 attached to the bottom of the cup, and the second air suction structure 22 of the first label sucking mechanism sucks the label part 602 attached to the side of the cup.

[0110] The second label sucking mechanism adsorbs the front side of the label. The label part adsorbed by the first air suction structure 21 of the first label sucking mechanism is handed over to the third air suction structure 311 of the second label sucking mechanism for adsorption, and the label part adsorbed by the second air suction structure 22 of the first label sucking mechanism is handed over to the fourth air suction structure 312 of the second label sucking mechanism for adsorption.

[0111] The third label sucking mechanism adsorbs the reverse side of the label. The top air suction structure 411 on the convex configuration sucks the label part attached to the bottom of the cup, and the side air suction structure 412 on the convex configuration sucks the label part attached to the side of the cup.

[0112] The process of the convex configuration being inserted into the cup mold and handing over the label to the cup mold of the cup-making mold can be that the cup mold is lifted to make the convex configuration inserted into the cup mold.

[0113] Refer to Figures 11-18 . Figures 12-18 The label placing device shown can be applicable to Figure 11 The label 600 shown is such that it includes a label part 602 attached to the side of the cup and a label part 601 attached to the bottom of the cup, and the two are separated. Or, the label 600 only includes the label part 602 attached to the side of the cup. The label part 602 attached to the side of the cup can surround the side of the cup.

[0114] For this embodiment, each label stacking storage position correspondingly has storage racks forming channels for the label part 602 attached to the side of the cup and the label part 601 attached to the bottom of the cup respectively. The mounting plate 1 also correspondingly has an outlet 12b for the label part 602 attached to the side of the cup and an outlet 12a for the label part 601 attached to the bottom of the cup corresponding to the label outlets of each label stacking storage position. The direction of the label stacking storage position formed by the storage racks, which is also the channel direction, and the directions of the label outlets 12a and 12b are obliquely downward. The vertically placed label stack can automatically move towards the label outlet by gravity after the label at the front end is taken away.

[0115] For the first label transfer device, the first air suction structure 21b of the first label suction mechanism may be a non-retractable air suction structure; the second air suction structure 22b of the first label suction mechanism includes a plurality of suction cups around the side of the first air suction structure, and their distribution is adapted to the curved shape when the label part 602 on the side of the cup is unfolded.

[0116] The structure of the transfer and turning mechanism of the first label suction mechanism is the same as that of the foregoing embodiment, and the same reference numerals are used.

[0117] A fixed frame 250 of a transfer suction label structure 25 for transferring the label part adsorbed by the second air suction mechanism of the first label suction mechanism to the fourth air suction structure for adsorption by the second label suction mechanism is further connected to the moving frame 243. The transfer suction label structure is a rotatable air suction structure, and its rotation axis 251 is perpendicular to the rotation axis of the first label suction mechanism when it turns. The transfer suction label structure 25 can be in the form of a plurality of suction cups.

[0118] As an alternative solution, the transfer suction label structure 25 can also be arranged at the position where the first label suction mechanism and the second label suction mechanism transfer the label. However, the transfer suction label structure 25 is connected to the moving frame 243 and can leave together with the moving frame 243 after the transfer is completed, which helps the equipment layout of the second label transfer device and avoids interfering with the second label transfer device.

[0119] The transfer suction label structure 25 can be driven to rotate through a rack and pinion structure. The rack 253 is connected to a driving mechanism such as a driving motor 252, a driving cylinder or a driving electric cylinder, the gear 254 is connected to the rotation axis 251, the rack 253 and the gear 254 are meshed, and a bearing for the rotation axis 251 is arranged on the fixed frame 250.

[0120] For the second label transfer device, the third air suction structure 311b of the second label suction mechanism may be a non-retractable air suction structure located at its bottom. The third air suction structure 311b is in the middle. The fourth air suction structure 312b includes a plurality of air suction structures around the third air suction structure 311b and facing outward. The reference numeral 313b is the air suction port of these air suction structures. The fourth air suction structure 312b can adsorb the lower half 6021 of the label part on the side of the cup and surround it outside the fourth air suction structure, while the upper half 6022 of the label part on the side of the cup protrudes from the second label suction mechanism.

[0121] In the transfer and pitch scaling mechanism of the second label sucking mechanism, the pitch scaling mechanism is the same as that in the foregoing embodiment and uses the same reference numerals for the drawings. In the transfer part of the transfer and pitch scaling mechanism, the movable frame 32 is connected to the rotating arm 321, and the rotating arm 321 is driven to rotate by the driving mechanism 322. When the movable frame makes a circular motion, the second label sucking mechanism is lifted and rotated from an inclined position to a horizontally upward position. The driving mechanism 322 can be a motor, a hydraulic cylinder, an electric cylinder, etc. A second lifting mechanism 323 is further provided on the rotating arm 321. The movable frame 32 is connected to the rotating arm 321 through the second lifting mechanism 323. The second lifting mechanism may include a cylinder and a lifting guiding structure.

[0122] For the third label transfer mechanism, the side suction structure 412b of the convex configuration 410b can adsorb and surround the upper half 6022 of the label portion attached to the side of the cup on its outer side. The top suction structure 411b of the convex configuration 410b is supported by a spring and is an elastically telescopic suction structure. The transfer mechanism of the third label sucking mechanism is the same as that in the foregoing embodiment. The reference numeral 413b is the suction port of these suction structures.

[0123] The label placing method using the above label placing device is as follows:

[0124] Place several stacks of labels in their respective label storage positions.

[0125] In the label storage position, the label portion 601 attached to the bottom of the cup and the label portion 602 attached to the side of the cup are placed on their respective storage racks. The label portion 601 attached to the bottom of the cup faces forward with its back side, and the label portion 602 attached to the side of the cup also faces forward with its back side.

[0126] A number of first label sucking mechanisms movably mounted on the moving frame corresponding to the number of label storage positions respectively suck the forward-facing side of the frontmost label in each label storage position. The moving frame is moved to the first label handover position. During the movement, the first label sucking mechanism turns under the guidance of the turning control rail 23. At the first label handover position, the label adsorbed by the first label sucking mechanism is handed over to the second label sucking mechanism for adsorption.

[0127] The first label suction mechanism returns. The second label suction mechanism is moved by its transfer and pitch scaling mechanism to the position for the second label handover. During the transfer process, the arrangement position of the second label suction mechanism changes from corresponding to the first label suction mechanism with a reduced pitch to corresponding to the third label suction mechanism. Since the first label suction mechanism returns, in addition to the movement mode in the previous embodiment of changing the second label suction mechanism from an inclined state to a vertically upward state during the rising process, in this embodiment, the position of the second label suction mechanism is lifted by circular motion and changed from an inclined state to a vertically upward state. After being turned horizontal, the lifting mechanism 322 vertically lifts the movable frame 32, enabling the second label suction mechanism and the convex configuration 410b to conduct label handover.

[0128] At the position for the second label handover, the convex configuration 410b of the third label suction mechanism corresponding to each second label suction mechanism receives the label. The label is adsorbed by the convex configuration 410b with the air suction function and then transferred to the cup-making mold. The convex configuration 410b and the cup mold 501 are matched.

[0129] The convex configuration is inserted into the cup mold to hand over the label to the cup mold of the cup-making mold.

[0130] During the above process:

[0131] The first air suction structure 21b of the first label suction mechanism sucks the reverse side of the label part 601 attached to the bottom of the cup, and the second air suction structure 22b of the first label suction mechanism sucks the reverse side of the label part 602 attached to the side of the cup.

[0132] When the first label suction mechanism hands over the label to the second label suction mechanism, the third air suction structure 311b of the second label suction mechanism directly sucks the front side of the label part attached to the bottom of the cup. The label part attached to the side of the cup is transferred by the handover label suction structure 25. The handover label suction structure 25 sucks the front side of the label part 602 attached to the side of the cup, then rotates upward or downward, making the reverse side of the label part 602 attached to the side of the cup face upward or downward and within the adsorption range of the fourth air suction structure 312b of the second label suction mechanism. The fourth air suction structure sucks the lower part 6021 of the reverse side of the label part attached to the side of the cup. The lower part 6021 of the label part attached to the side of the cup surrounds the fourth air suction structure 312b, and the upper part 6022 of the label part attached to the side of the cup protrudes from the second label suction mechanism.

[0133] The top air suction structure 411b of the third label suction mechanism's convex configuration is a retractable air suction structure. When the second label suction mechanism transfers the label to the third label suction mechanism, the top air suction structure 411b of the convex configuration in the third label suction mechanism adsorbs the reverse side of the label part at the bottom of the cup. The side air suction structure 412b on the convex configuration adsorbs the upper part 6022 of the reverse side of the label part on the side of the cup, and the upper part of the label part on the side of the cup surrounds the side air suction structure 412b. Moreover, after the third label suction mechanism and the second label suction mechanism are separated, the top air suction structure 411b pops out, and the overall height of the convex configuration matches the depth of the cup mold cavity.

[0134] The process of inserting the convex configuration into the cup mold and transferring the label to the cup mold of the cup-making mold can be that the convex configuration is inserted into the cup mold by lifting the cup mold.

[0135] The above are only specific embodiments of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the protection scope of the present invention.

The upper part of the label part attached to the side of the cup surrounds the outside of the side air sucking structure. And after the third label sucking mechanism and the second label sucking mechanism are separated, the top air sucking structure pops out.
