Description

Paper mould belt net transferring method

Technical Field

The invention relates to the field of paper mould (such as, but not limited to, disposable tableware and disposable work packages) forming, in particular to a paper mould belt mesh transferring method.

Background

With the continuous development of economy and the continuous progress of scientific technology, extremely rich substance consumer products are provided for the life of people, and paper molds made of ecological plant fiber pulp are one of a plurality of substance consumer products.

As is well known, paper molds can be classified into tableware (such as, but not limited to, disposable snack boxes), drinking tools (such as, but not limited to, disposable cups), and kits (such as, but not limited to, disposable packaging containers), which are produced without separating from the wet blank forming step, the step of drying the wet blank to form a dry blank, the step of trimming the dry blank to form a product, and the step responsible for wet blank and dry blank transfer.

In the transferring process of the wet blank and the dry blank, the wet blank is taken away from the wet blank forming machine and put into the dry blank forming machine, and meanwhile, the dry blank at the dry blank forming machine is taken away and transferred to the subsequent (for example, a stacking receiving table or an edge cutter) by the vacuum adsorption of the wet blank by the wet blank profiling jig matched with the wet blank in shape and the vacuum adsorption of the dry blank by the dry blank profiling jig matched with the dry blank in shape, which are arranged at the tail end of the transferring manipulator. Because the transfer of wet blank needs to be by means of the vacuum adsorption of wet blank profiling jig to wet blank and the transfer of dry blank needs to be by means of the vacuum adsorption of dry blank profiling jig to dry blank, no matter wet blank or dry blank, gaps exist more or less, and thus the waste of air sources at the wet blank profiling jig and the dry blank profiling jig can be caused.

Therefore, there is a need to provide a paper die belt screen transfer method that ensures a smoother transfer of the screen frame in a narrow space with reduced air source wastage to overcome the above-mentioned drawbacks.

Disclosure of Invention

The invention aims to provide a paper mould belt net transferring method which ensures a net frame to be transferred more smoothly in a narrow space under the condition of reducing air source waste.

In order to achieve the above purpose, the technical scheme of the invention is as follows: the paper mould belt net transferring method includes the following steps: (1) The XZ shaft transferring modules drive the Y shaft transferring modules on the left side and the right side to translate along with the screen frame feeding and discharging mechanisms on the portal frame along the XZ shaft until the screen frame feeding and discharging mechanisms are aligned with the wet blank forming machine along the Y shaft direction; (2) The Y-axis transfer modules on the left side and the right side synchronously drive the net frame feeding and discharging mechanisms to extend into the wet blank forming machine after the mold opening, and the net frame supporting mechanism at the supporting position in the wet blank forming machine supports the empty net frame sucked by the first vacuum suction head in the net frame feeding and discharging mechanisms from below; (3) The XZ shaft transferring modules drive the Y shaft transferring modules on the left side and the right side to downwards translate along the Z shaft direction together with the screen frame feeding and discharging mechanism, so that a second vacuum suction head in the screen frame feeding and discharging mechanism sucks a screen frame with wet blanks on a lower mould of the fishing paddle, and simultaneously, a first vacuum suction head in the screen frame feeding and discharging mechanism is also moved away from an empty screen frame supported by a screen frame supporting mechanism; (4) The Y-axis transfer modules on the left side and the right side synchronously drive the net frame feeding and discharging mechanisms to move away from the wet blank forming machine after the die, and the XZ-axis transfer modules drive the Y-axis transfer modules on the left side and the right side to move to a position aligned with the dry blank forming machine after the die opening together with the net frame feeding and discharging mechanisms; (5) The Y-axis transfer modules on the left side and the right side synchronously drive the net frame feeding and discharging mechanisms to extend into the dried blank forming machine after the die opening along the Y-axis direction, and the XZ-axis transfer modules drive the net frame feeding and discharging mechanisms to translate along the Z-axis direction, so that the second vacuum suction heads in the net frame feeding and discharging mechanisms transfer the net frame with wet blanks into the dried blank forming machine after the die opening, and the first vacuum suction heads in the net frame feeding and discharging mechanisms suck the net frame with the dried blanks at the dried blank forming machine; and (6) synchronously driving the net frame feeding and discharging mechanisms to move away from the die by the Y-axis transferring modules on the left side and the right side, and driving the Y-axis transferring modules on the left side and the right side to move to a dry blank discharging position together with the net frame feeding and discharging mechanisms by the XZ-axis transferring modules so as to completely take away the dry blanks in the net frame with the dry blanks sucked by the first vacuum suction head, thereby completing one period of net frame transferring.

Preferably, the first vacuum suction head and the second vacuum suction head each suck the net frame from the periphery of the net frame, and the first vacuum suction head is used for sucking the net frame upwards, and the second vacuum suction head is used for sucking the net frame downwards.

Preferably, the XZ axis transferring module drives the Y axis transferring module on the left side and the right side to do XZ axis translation on the portal frame together with the net frame feeding and discharging mechanism in a matching mode of the motor, the gear and the linear rack.

Preferably, the Y-axis transferring modules at the left side and the right side drive the left side and the right side of the net frame feeding mechanism to synchronously stretch and translate through the restraint of a synchronous shaft.

Preferably, before the step (3), the pulp dragging lower die is driven by a lifting mechanism in the wet blank forming machine to be matched with a wet blank upper die in the wet blank forming machine in a die clamping mode, so that the wet blank in the wet blank-carrying net frame on the pulp dragging lower die is jointly formed by the pulp dragging lower die and the wet blank upper die and the redundant pulp is squeezed out, and then the lifting mechanism drives the pulp dragging lower die and the wet blank-carrying net frame on the pulp dragging lower die to descend downwards to a position for a second vacuum suction head to suck the wet blank-carrying net frame.

Preferably, in the step (3), when the second vacuum suction head sucks the net frame with the wet blank and the first vacuum suction head moves away from the empty net frame supported by the net frame supporting mechanism, the XZ shaft moving and transferring module and the Y shaft moving and transferring module drive the net frame loading and unloading mechanism to move horizontally towards the dry blank forming machine together, and in the process of moving horizontally towards the dry blank forming machine, the lifting mechanism in the wet blank forming machine drives the pulp dragging lower die to be lifted to a position contacting the empty net frame supported by the net frame supporting mechanism, and the supported empty net frame is placed on the pulp dragging lower die by the net frame supporting mechanism; then, the lifting mechanism drives the pulp dragging lower die to move downwards together with the empty net frame on the pulp dragging lower die to sink into the pulp pool of the wet blank forming machine.

Preferably, in step (5), the dry blank upper die makes the net frame with the dry blank remain on the dry blank upper die through vacuum adsorption in the die opening process of the dry blank forming machine, correspondingly, the net frame feeding and discharging mechanism in the dry blank forming machine extending into the die opening machine makes descending and lifting translation under the driving of the XZ shaft transfer module, so that the second vacuum suction head transfers the sucked net frame with the wet blank to the dry blank lower die in the die opening dry blank forming machine, and the first vacuum suction head sucks the net frame with the dry blank remaining on the dry blank upper die after die opening.

Compared with the prior art, the paper mould belt mesh transfer method disclosed by the invention has the advantages that the mesh frame loading and unloading transfer is carried out in a mesh frame sucking mode by means of the cooperation of the steps (1) to (6), the vacuum adsorption of a profiling jig on a wet blank or a dry blank is not needed, and the waste of air sources is reduced; the telescopic translation of the screen frame feeding and discharging mechanism along the Y-axis direction is synchronously driven by the Y-axis transferring modules beside the left side and the right side, so that clamping caused by asynchronous sliding of the left side and the right side of the screen frame feeding and discharging mechanism is avoided, and the bearing capacity of the Y-axis transferring modules to the screen frame feeding and discharging mechanism is increased, so that smooth reliability of screen frame feeding and discharging transferring can be ensured under the condition of reducing air source waste. In addition, the gantry manipulator is matched with the wet blank forming machine and the dry blank forming machine respectively so as to be suitable for a narrow space.

It can be understood that, according to actual needs, the lifting motor 3612 can use belt transmission, chain transmission or gear transmission to drive the lifting frame 361 to lift in addition to the cooperation of the upper and lower screw rods 363 and the upper and lower nuts 364 to drive the lifting frame 361 to lift, wherein, for the belt transmission, two belt wheels which are positioned beside the upper wet blank mold 32 and are arranged in a top-bottom manner and are sleeved on the two belt wheels are arranged on the wet blank frame 21, and one side of the belt is fixedly connected with the lifting frame 361; for chain transmission, two chain wheels which are positioned beside the upper die 32 of the wet blank and are arranged in a top-to-bottom manner and a chain sleeved on the two chain wheels are arranged on the wet blank frame 21, and one side of the chain is fixedly connected with the lifting frame 361; for gear transmission, an upper straight rack and a lower straight rack which are positioned beside the upper die 32 of the wet blank and a gear meshed with the upper straight rack and the lower straight rack for transmission are fixed on the upper rod 363 and the lower rod 363; the purpose that the lifting motor 362 drives the lifting frame 361 to lift to any position can be achieved in the above mode.

It should be noted that the dry blank in the frame 200 sucked by the first vacuum suction head 22 may be removed by an external material taking robot or a material taking robot. More specifically, the following is:

in step S003, when the second vacuum suction head 23 sucks the wet blank-carrying frame 200 and the first vacuum suction head 22 are moved away from the empty frame 200 supported by the frame support mechanism 33, the XZ-axis transfer module 12 and the Y-axis transfer module 13 drive the frame loading and unloading mechanism 20 to translate toward the dry blank forming machine 40 together, and in the process of translating toward the dry blank forming machine 40, the lifting mechanism 36 in the wet blank forming machine 30 drives the pulp-taking lower mold 35 to be lifted to a contact position with the empty frame 200 supported by the frame support mechanism 33, and the supported empty frame 200 is placed on the pulp-taking lower mold 35 by the frame support mechanism 33; next, the lifting mechanism 36 drives the lower pulp dragging mold 35 and the empty net frame 200 on the lower pulp dragging mold 35 to move downwards to sink into the pulp tank 34 of the wet blank forming machine 30, so as to meet the requirement of redeposition of the empty net frame 200 on the lower pulp dragging mold 35 to form wet blanks, but the invention is not limited thereto.

Specifically, in the process of rotating the first rotating wheels 133 on the left and right sides, the fast one drives the slow one through the synchronizing shaft 135, so that the rotation of the first rotating wheels 133 on the left and right sides is synchronized.

Wherein, the first vacuum suction head 22 and the second vacuum suction head 23 each suck the net frame 200 from the periphery of the net frame 200, and the first vacuum suction head 22 is used for sucking the net frame 200 upwards, and the second vacuum suction head 23 is used for sucking the net frame 200 downwards, so that the purpose of the arrangement is to improve the speed and efficiency of feeding and discharging transfer of the net frame 200. Meanwhile, the XZ axis transferring module 12 drives the Y axis transferring module 13 on the left side and the right side to do XZ axis translation on the portal frame 11 together with the screen frame feeding and discharging mechanism 20 in a matching mode of a motor, a gear and a linear rack so as to ensure the accurate reliability of transferring the screen frame 200; in addition, the Y-axis transferring modules 13 on the left and right sides drive the left and right sides of the frame feeding and discharging mechanism 20 to synchronously stretch and translate under the constraint of a synchronous shaft 135.

Compared with the prior art, the paper mould belt mesh transfer method disclosed by the invention has the advantages that the mesh frame 200 loading and unloading transfer is carried out in a manner of sucking the mesh frame 200 by means of the cooperation of the steps S001 to S006, so that a profiling jig is not required to carry out vacuum adsorption on wet blanks or dry blanks, and the waste of air sources is reduced; the telescopic translation of the screen frame loading and unloading mechanism 20 along the Y-axis direction is synchronously driven by the Y-axis transferring modules 13 beside the left side and the right side, so that clamping caused by asynchronous sliding of the left side and the right side of the screen frame loading and unloading mechanism 20 is avoided, and the bearing capacity of the Y-axis transferring modules 13 to the screen frame loading and unloading mechanism 20 is increased, so that smooth reliability of loading and unloading transferring of the screen frame 20 can be ensured under the condition of reducing air source waste. In addition, the gantry manipulator 10 is matched with the wet blank forming machine 30 and the dry blank forming machine 40 respectively so as to adapt to a narrow space.

Note that, in fig. 2 and 3, the positive direction of the X axis is the left-to-right direction of the gantry 11, the positive direction of the Y axis is the front-to-back direction of the gantry 11, and the positive direction of the Z axis is the bottom-to-top direction of the gantry 11.
