Description

Technical Field

[0001] The invention relates to the technical field of equipment for preparing plastic cups, bowls, dishes, covers and the like, and in particular to a cup-making mould of a plastic cup-making machine. Background Art

[0002] Disposable plastic tableware for daily use, such as disposable cups, bowls, plates, lids, boxes and other products, there are two main ways to produce such disposable plastic tableware in the prior art. The first is to adopt the injection molding method. Although the raw materials have no corners and can be fully utilized, injection molding production has problems such as expensive molds, long mold processing and debugging cycles, and easy loss of market opportunities. Moreover, the number and speed of each mold in injection molding production cannot be compared with sheet air pressure thermoforming cup making machines. The second method is to use a sheet thermoforming machine to punch out the mold. The product prepared by this method has a pure color and no pattern on the appearance, and the product grade is low. Even if the product is printed on a curved surface, the clarity and texture of the product's graphics cannot be compared with injection molding or in-mold labeling. Therefore, the applicant of the present invention develops an in-mold labeling production line to achieve the affixing of rich graphic labels while producing and preparing products, which can greatly improve the aesthetics of the product and increase the added value of the product. However, the in-mold labeling production line of the prior art requires eleven actions for each mold, and an in-mold labeling robot needs to be added to the production line during in-mold labeling. The cup-making and stacking conveying robot alone needs to perform several actions for each mold. For example, the in-mold labeling robot must first wait for the unloading robot to descend and vacate a position before the in-mold labeling robot can complete the four actions of translational entry, descending to place labels, ascending and translational exit. That is, the in-mold labeling robot connected to the traditional flip mold requires nine actions to complete the production of one mold product, and the connection to the upper and lower pressing thermoforming cup making machine requires eleven actions to complete. Whether it is connecting the flip mold or the upper and lower pressing for in-mold labeling, the traditional in-mold labeling technology still has many actions and low efficiency.

[0003] Therefore, in view of the existing problems in the prior art, there is an urgent need to provide a cup-making mold technology that can utilize the existing cup-making machine to ensure low investment cost, low mold modification cost and short mold making cycle, which is conducive to seizing the initiative, increasing product added value and streamlining production line operations and high work efficiency.

[0020] Beneficial effects of the present invention:

[0021] The cup-making lifting built-in unloading device of the present invention is installed on the upper mold of the cup-making machine, and the upper mold is provided with a plurality of lifting molds corresponding to the molding cavity of the lower mold. The cup-making mold involved in the present invention is improved based on the traditional preparation mold of the prior art. The interior of the lifting mold is hollow and a lifting rod is installed on the upper part. The lifting rod has a lifting airway rod inside. The lower end of the lifting airway rod is installed with a suction cup, which is connected to the airway and connected to the positive and negative pressure generating device through the air nozzle. Compared with the prior art, it has the following advantages:

[0022] (1) The cup-making mold mechanism using the cup-making lifting and built-in unloading device of the present invention can realize multi-stage lifting and unloading. The lifting drive device drives the lifting rod, the lifting airway rod and the lifting drive device to lift and lower together. When the cup-making mold is opened, the lifting drive device makes the lifting airway rod extend out of the lifting mold alone and contact the product generated by the lower mold to suck and take the material. When taking the material, the push rod of the lower mold needs to cooperate to slightly lift the product in the molding cavity to realize the material taking and transmission in the cup-making mold.

[0023] (2) When the mold is closed and the air pressure is used to complete the forming and exhausting in normal action, the pull-up drive device and the built-in unloading device of the pull-up complete their lifting action according to the programming and cool the bottom of the product with cold air at the same time. When the lower mold descends, the bottom of the product is cooled to the appropriate temperature and the negative pressure is converted. The air and action of the lower mold on the bottom of the product pushes the product to the suction cup to complete the material removal under the cooperation of the suction cup negative pressure, and the lower mold continues to descend into place without stopping. In this way, the time of its descent is reduced, which has the beneficial effect of reducing the time of the two actions of the material removal robot moving horizontally into the mold body and descending to take the material. The air nozzle on the lifting airway cools the bottom of the product with cold air, which creates precious time for ensuring the quality and high-speed transmission.

[0024] (3) When the lower mold is lowered into place, the in-mold labeling robot moves horizontally into place, and unloads the material while the lower mold rises to receive the label. When the lower mold is lowered after receiving the label, the lifting and lifting airway rods of the device are also reset and standby at the same time, thereby reducing the two actions of the white cup special robot descending to take the material and rising after taking the material.

[0025] (4) The lifting structure of the lifting airway rod connecting plate of the cup making, lifting and unloading device of the present invention is characterized in that the bearing seat is fixed to the support frame, the transmission shaft is installed on the bearing seat, and the bearing controls the fixed gear and the rack to mesh with each other, thereby realizing high-precision lifting at the meshing point, and the lifting airway rod connecting plate is fixed at the rack and the lower end of the rail to drive the synchronous lifting movement of all the lifting airway rods on the lifting airway rod connecting plate, which has high precision and can move repeatedly.

[0026] (5) The support frame of the cup-making lifting and unloading device is fixed to the lifting cross arm, and the slider is provided with a rail to fix the toothed bar and the bearing seat to install the transmission shaft and the gear shaft to connect the motor so that the whole device can also drive the lifting cross arm to rise and fall with the lifting drive during the lifting movement, so that the independent lifting of each device is not affected.

[0027] (6) The motor fixes the suction cup airway rod connecting plate through the lower end of the lifting rack on the outer side of the lifting cross arm, driving multiple lifting airway rods fixed to the suction cup airway rod connecting plate, so that the lifting cross arm drives the lifting connecting plate to move up and down while also driving the suction cup airway rod connecting plate to carry the suction cup to move up and down. While all the mechanical and transmission components of the driving device are configured and the motor is lifted and lowered synchronously, it affects the independent drive of the suction cup lifting motor fixed. The rack and rail located on the outer side of the lifting cross arm are fixed as a whole and slide on the slider on the support frame to achieve fixed-point limiting, forming a precise vertical lifting movement route. At the same time, the bearing-mounted rotating shaft fixed gear meshing lifting rack installed on the support frame is installed with one static and one dynamic installation to ensure the transmission accuracy of the gear meshing lifting rack, so as to achieve the beneficial effect of the motor connecting the rotating shaft and the gear rotating shaft, and the gear meshing lifting rack driving the suction cup lifting connecting plate to move independently.

[0028] (6) The unique structure of this device makes it easy for the controller to give instructions so that other devices can cooperate with this device to add the in-mold labeling function, without reducing the six actions of traditional technology to complete the molding, picking up and conveying. When the in-mold labeling robot completes the label transmission and material picking and resets to the receiving and unloading station, the lower mold rises and falls according to the programming of this device, and the multifunctional material picking and conveying robot and the label conveying robot also use the rise and fall of the lower mold to complete the product molding and the device completes various actions according to the programming. During the time period, the label is transferred to the labeling mold of the in-mold labeling robot and descends, and the multifunctional material picking and conveying robot and the label transfer conveying device also complete the material receiving and conveying in the same time period, including the product completion before the lower mold falls into place and the suction cup completes the material picking and rising to the programmed specified position, and completes the contraction of the labeling row spacing to align with the ten lines of the mold cavity. At this point, the space for the in-mold labeling robot to move is reduced, and the space for the in-mold labeling robot to move is reduced by five actions in total, so that the white cup production robot is connected to the cup making machine in six actions to complete a limited number of stacking and conveying, and the in-mold labeling conveying and packing are increased on the basis of ensuring that the six actions of one mold are not increased in the traditional technology. The application of this device with the above-mentioned device and robot subverts the traditional technology and has achieved a breakthrough beneficial effect. Compared with the prior art, the present invention does not need to set up a separate unloading robot, and the in-mold labeling robot does not need to wait for the unloading robot to take out the material before taking action, which saves the action of using an additional robot to transport the product, and the action process is simpler and the production efficiency is higher.

The air source or the positive and negative pressure generating device introduces high-pressure gas into the air nozzle according to the preset programming so that the high-pressure gas enters the airway and airway connecting piece 1-11 of the lifting airway rod 1-4 and the corresponding suction cup 1-5. The PLC controller controls the opening and closing of the functional electromagnetic valve so that the cold air cools the bottom of the product, the negative pressure sucks the product to take the material or converts the positive pressure air to blow and unload. Due to the subversion of the original structure control mode and action, especially the independent coordination of each functional solenoid valve to switch the functional air pressure, the prerequisite for high speed and high quality is created, so that the suction cup can quickly take the material without leaving any marks and ensure the quality.At the same time, the lower tail end of the lifting airway rod 1-4 is fixed with an airway connecting piece 1-11, and the number of suction cups 1-5 installed on the airway connecting piece 1-11 is set according to the molding cavity 2-1 of the lower mold 2 of the cup making machine. When the airway connecting piece needs to be fixed in direction and angle, the airway connecting piece 1-11 becomes a lifting limiter, and the lifting mold 1-1 is provided with a hollow lifting slide cavity 1-21 corresponding to the airway connecting piece 1-11. In this embodiment, the suction cup airway rod connecting plate 4 is located above the lifting connecting plate 3, and the lifting connecting rod 6-3 passes through the suction cup airway rod connecting plate 4 and is fixedly connected to the lifting rod cross arm 6-2, and the lifting airway rod 1-4 and the lifting rod 1-2 move independently.

[0060] When the cup making machine closes the mold, the pulling mold descends, and the molding solenoid valve is opened synchronously to let in high-pressure gas to complete the shaping and then exhaust. At the same time, the pulling mold 1-1 and the suction cup 1-5 rise or fall in opposite directions, and the air nozzle 1-7 lets in cold air to cool the bottom of the product. While the lower mold 2 descends, the pulling mold 1-1 and the suction cup 1-5 are synchronously lowered to the bottom of the product to cool to a suitable temperature; the other air nozzle 1-7 is connected to the positive and negative pressure generating device through the solenoid valve and the air pipe to realize the positive and negative pressure conversion. At the same time, the lower mold 2 of the cup making machine is synchronously lowered to the preset programming position, and the bottom mold cylinder 2-5 of the product is actuated to push the product to the suction cup 1-5. After the suction cup 1-5 completes the product suction, it rises to the position specified by the PLC, and the lower mold 2 continues to descend without stopping to the specified position preset by the PLC controller. This position can be set according to the actual situation of the production line.

[0061] Among them, it cooperates with the in-mold labeling material collection and conveying robot B of the production line. The in-mold labeling material collection and conveying robot B is continuously translated to the outside of the gantry column 2-6 of the cup making machine. The sliding parts of the longitudinal sliding pair B3 and the transverse sliding pair B4 of the in-mold labeling material collection and conveying robot B are driven by the driving source, and the sliding parts carry the labeling mold B1 according to the spacing of the molding cavity 2-1 and translate into the mold 2. The lower mold 2 is driven by the multi-tonnage large-scale lifting device 9 of the lever push-pull structure to rise and receive the label. At the same time, the making The lifting airway rod 1-4 of the built-in unloading device of the cup lifting device is synchronously lowered, and the suction cup 1-5 is unloaded by turning the negative pressure into positive pressure. The unloading component B2 of the in-mold labeling material taking and conveying robot B cooperates to receive the material from the suction cup 1-5. When the lower mold 2 completes the label taking and descends to the right position, the lifting mold 1-1 and the suction cup 1-5 of the lifting airway rod 1-4 are all raised and reset after unloading; then the film feeding motor 2-7 drives the film feeding and in-mold labeling material taking and conveying robot B to move and reset with the product to the unloading station. The multi-tonnage large-scale lifting device 9 with a lever push-pull structure is also another lifting drive device that can realize the raising or lowering of the lower mold.

[0062] Among them, when the in-mold labeling material taking and conveying robot B moves horizontally with the product to the outside of the gantry column 2-6, the labeling mold B1 of the in-mold labeling material taking and conveying robot B slides to the label row placement position C1 of the corresponding label transfer conveyor C to open the distance to meet the action needs of the labeling mold B1 receiving the label and the label transfer conveyor transferring the label function. When the lower mold 2 rises to the upper mold 1-12 to close the mold, the air pressure and the lifting mold are lowered to complete the punching and shearing. At the same time, the device completes all the actions and pre-programmed needs to be completed according to the PLC in the process of forming the closed mold product. The lower mold 2 descends to the specified position according to the pre-programmed method, the multifunctional material receiving and conveying robot F completes the material picking and conveying, the label transfer conveying device C descends after synchronously conveying the label, and the in-mold labeling material picking and conveying robot B cooperates with the built-in unloading device of the cup making and lifting under the control of the PLC, as well as the lower mold 2 to complete the unloading, label picking and labeling. The mold B1 aligns with the shrinkage standby of the forming cavity 2-1 to complete all the actions of one mold; such repeated continuous cycle actions are used to increase the in-mold labeling conveying function, while ensuring the beneficial effect of six actions in one mold production according to the original white cup production.

[0063] The technical solution of the present invention utilizes the heating temperature control system and sheet feeding device of the original thermoforming machine and utilizes the original mold, with low modification cost and high speed. At the same time, the cup-making mold mechanism of the present invention can realize multi-level lifting and unloading. The lifting drive of the cup-making pulling mold and the lifting drive device of the suction cup can be lifted and lowered independently, and the lifting drive device can make the lifting airway rod drop down alone when the cup-making mold is opened to extend the pulling mold and contact the product in the molding cavity of the lower mold and suck and take the material. When taking the material, the cup bottom lifting device of the lower mold cooperates to slightly lift the product in the molding cavity. The lower mold and its cup bottom lifting device and other components of the cup-making machine are all existing equipment, so their specific structure and working principle are not repeated here. Compared with the prior art, the present invention does not need to set up a separate unloading robot, and can use the lifting airway rod and the suction cup to pick up materials while the lower mold is descending. Therefore, the in-mold labeling robot does not need to wait for the lower mold to fully descend and the traditional unloading robot to enter between the upper mold and the lower mold to pick up materials. The lower mold is raised and lowered. The device completes the action time period according to the programming. After the in-mold labeling material picking and conveying robot is translated and reset, the upper multifunctional material picking and conveying robot and the in-mold labeling material picking and conveying robot and the lower label transfer conveying robot simultaneously move to complete the material picking and conveying, and then descend after the label is conveyed, thereby reducing the action, simplifying the process and saving time.

[0064] The in-mold labeling robot at this time can adopt the technical solution recorded in the patent document with publication number CN110217455A, but it is necessary to provide a pick-up and unloading suction cup on the upper part of the single-row and multi-row sliding support plate of the in-mold labeling robot. The pick-up and unloading suction cup is connected to the positive and negative pressure generating device and cooperates with the cup-making lifting built-in pick-up and unloading device of the present invention to work together, thereby achieving the purpose of reducing actions and improving work efficiency, so that the suction cup can quickly pick up materials without leaving marks and ensure the quality, so that the in-mold labeling robot not only ensures that the original in-mold labeling robot completes the label transmission function but also replaces all the actions of the original white cup pick-up and unloading robot, that is, after the in-mold labeling robot enters, the lower mold rises to receive the label, and the in-mold labeling robot unloads the label. At the same time, the suction cups 1-5 of this device independently descend under the action of the lifting drive device and transfer the product to the pick-up and unloading suction cup of the in-mold labeling robot, eliminating the additional use of the pick-up and unloading robot transmission step, the action process is simpler, and the production efficiency is higher.

[0065] The cup-making lifting built-in unloading device of this embodiment is suitable for a one-mold six-action thermoforming in-mold labeling conveying and packing production line.

The stacking conveying and packing unit includes an alternating stacking conveying device G, a transfer conveying robot H, two single-row whole-line stacking lateral pushing devices I, a limited-position material receiving and flipping transverse quantitative conveying device J, a layer-by-layer material receiving and conveying device L, and a multi-specification and shape packing conveying device M. The multi-functional material taking and unloading conveying robot takes the material from the cup making machine A and stacks the material on one of the receiving trays of the alternating stacking conveying device G. The transfer conveying robot H takes the material from the receiving tray of the alternating stacking conveying device G and transfers it to the single-row whole-line stacking lateral pushing device I for stacking into a whole The single-row whole-strip overlapping lateral pushing device I conveys multiple strips of materials to the limited material receiving and flipping transverse quantitative conveying device J, and the limited material receiving and flipping transverse quantitative conveying device J pushes the materials to the layer receiving and conveying device L, and the layer receiving and conveying device L pushes the materials layer by layer to the cartons of the multi-specification and shape packing conveying device M. The multi-specification and shape packing conveying device M is loaded with cartons. When the materials are fed into the cartons, the multi-specification and shape packing conveying device M does not need to be lifted or lowered, and the layer receiving and conveying device L can be lifted or lowered to push the materials into the carton layer by layer. It should be noted that a material receiving and quantitative conveying platform K can also be provided between the limited material receiving and flipping transverse quantitative conveying device J and the layer receiving and conveying device L, and the material receiving and quantitative conveying platform K is used to convey the materials on the limited material receiving and flipping transverse quantitative conveying device J to the layer receiving and conveying device L.
