Description
Technical Field
The present invention relates to a system connected to a glass forming machine that receives a flat glass sheet, forms the glass sheet into a three-dimensional shape, and then takes out the glass sheet and a mold to transfer the glass sheet and the mold.
Background
The three-dimensional glass is glass having a curved surface portion, and is recently mainly used for portable terminals such as smartphones and smartwatches.
Glass having a three-dimensional shape can be produced by a grinding method or a press molding method, but the grinding method has a problem that it is not suitable for mass production and has a lower quality than the press molding method. Therefore, in recent years, press molding methods have been widely used in which a flat plate-shaped (two-dimensional) glass blank is loaded into a mold, and the three-dimensional glass blank is molded by sequentially subjecting the mold to a high-temperature heating step, a molding step, and a cooling step.
For example, in prior registered patent No. 10-1775333 (registered on 31/08/2017) of the present applicant, there is disclosed a glass molding machine which takes out a flat plate-like glass after it is molded into a three-dimensional shape.
In order to automatically realize the process of feeding a flat plate-shaped glass semi-finished product into a glass forming machine and taking out a formed three-dimensional glass finished product, a system for transferring glass and a mold is connected to the glass forming machine.
For example, in the applicant's prior registered patent No. 10-1914436 (registered by 29/10/2018), a system for transferring glass and molds connected to a glass molding machine is disclosed.
A glass forming machine, a glass and mould transfer system connected with the glass forming machine, and a glass forming system for producing glass with three-dimensional shape. In order to arrange as many glass forming systems as possible in a limited space, it is necessary to reduce the size of the glass and mold transfer system.
However, in the conventional glass and mold transfer system, a plurality of robots and related devices are individually provided to perform a specific function, which causes an increase in the size of the glass and mold transfer system. Therefore, to reduce the size of the glass and mold transfer system, it is necessary to reduce the number of robots and associated equipment.
Meanwhile, in the glass and mold transfer system, the speed at which the glass and mold are transferred affects the overall cycle time of the automated process for forming the flat glass semi-finished product into a three-dimensional shaped glass finished product. Therefore, there is a need for research into a method of rapidly transferring glass and molds in a more efficient movement path, and a transfer system for implementing the same.
If new ways of moving the glass and the mold can be developed through such studies, the glass production method of the three-dimensional shape will be redefined.
Disclosure of Invention
The invention provides a transfer system capable of further simplifying the conventional glass and mold transfer process, and a glass and mold transfer process. Meanwhile, the present invention is for providing a glass production method of a three-dimensional shape which is further simplified using the above-mentioned processes.
Specifically, a first object of the present invention is to provide a glass and mold transfer system capable of reducing the size of the entire facility by integrating a plurality of robots and some of the related devices, each of which is provided separately to perform a specific function.
A second object of the present invention is to provide a glass and mold transfer system, a glass and mold transfer process, and a glass production method using the three-dimensional shape of the above process, which can simultaneously perform at least a part of the processes of processing a glass semi-finished product, a glass finished product, a lower mold, and an upper mold while minimizing delay.
To achieve the first object of the present invention, the present invention discloses a glass and mold transfer system, comprising: a first robot which takes out the glass semi-finished product from the first cassette and puts it into a glass cleaning machine, and places the glass semi-finished product, which has been aligned and cleaned in the glass cleaning machine, on the lower mold located at a first position; a second robot that grips the lower mold taken out of the glass molding machine at a second position and moves to the first position; and a third robot that grips and lifts the upper mold at the second position, and that is loaded on the second chuck by sucking the glass product, and that moves the upper mold to the first position.
The glass and mold transfer system includes a single mold cleaning machine that sequentially cleans the lower mold and the upper mold while the lower mold and the upper mold are moved to the first position.
The first and second robots are configured to sequentially transfer the lower mold and the upper mold to the mold cleaning machine, respectively.
Above-mentioned glass cleaning machine includes: a glass cleaning machine main body which is provided with an opening part opened to the upper side and is connected with a dust collecting device which collects dust or foreign matters falling to the inside; a cover configured to open and close the opening; a glass aligning unit for aligning the glass semi-finished product stored in the glass cleaning machine main body; and an ion blower which is provided inside the glass washer body and ejects ionized air to the opening.
Meanwhile, in order to achieve the first object of the present invention, the present invention discloses a glass and mold transfer system comprising: a plurality of robots that take out and clean a plate-shaped glass semi-finished product from a first cassette, place the plate-shaped glass semi-finished product in a lower mold and an upper mold, and put the plate-shaped glass semi-finished product into a glass molding machine, and load a molded three-dimensional glass finished product on a second cassette by separating the lower mold and the upper mold taken out of the glass molding machine, and restore the lower mold and the upper mold taken out of the glass molding machine to predetermined positions so as to reuse the plate-shaped glass semi-finished product in the putting; and a single mold cleaning machine for sequentially cleaning the lower mold and the upper mold while the lower mold and the upper mold are returned to the preset positions, wherein some of the plurality of robots are configured to sequentially transfer the lower mold and the upper mold to the mold cleaning machine.
In order to achieve the second object of the present invention, the step of taking out the glass semi-finished product from the first cassette and putting it into the glass washer is performed during the step of taking out the glass finished product from the glass forming machine and separating the lower mold and the upper mold from each other.
Further, the step of transferring the lower mold to the mold cleaning machine is performed during a period of performing the step of cleaning the glass semi-finished product by the glass cleaning machine and simultaneously performing the step of attaching the glass finished product to the second chuck by suction. In the process, the lower die can be cleaned through the die cleaning machine.
And a step of transferring the upper mold to the mold cleaning machine while the step of attaching the cleaned glass intermediate product to the cleaned lower mold by suction is performed. In the process, the upper die can be cleaned through the die cleaning machine.
In addition, in order to achieve the second object of the present invention, the present invention discloses a method for producing a three-dimensional shaped glass, comprising: taking out the plate-type glass semi-finished product from the first clamping seat, cleaning the plate-type glass semi-finished product by using a glass cleaning machine, and putting the plate-type glass semi-finished product into a glass forming machine; taking out the formed three-dimensional glass product from the glass forming machine and loading the glass product on a second clamping seat; and a step of transferring the lower mold and the upper mold taken out of the glass molding machine to be reused in the charging step; in the step of transferring for the reuse, the lower mold and the upper mold are moved to be separated from each other, and are sequentially cleaned by a single mold cleaning machine in the process of the movement.
The effects of the present invention obtained by the above-described solution are as follows:
first, since the glass preform is processed by the first robot, the lower mold is processed by the second robot, and the glass preform and the upper mold are processed by the third robot, the number of robots separately provided to perform a specific function can be reduced compared to the conventional one.
Further, since the lower die and the upper die are sequentially cleaned by the single die cleaning machine in the process of sequentially transferring the lower die and the upper die to the preset positions, the number of devices can be reduced compared to the case where the lower die cleaning unit and the upper die cleaning unit are separately provided in the related art.
Meanwhile, since it is formed that not only the cleaning of the glass semi-finished product but also the alignment is performed in the glass cleaning machine, the number of equipment can be reduced compared to the related art in which the cleaning unit of the glass semi-finished product and the position adjusting unit of the glass semi-finished product are separately provided.
Thus, according to the present invention, the glass and mold transfer process and the transfer system for realizing the process can be further simplified. By simplifying the process and shortening the transfer route, the accuracy of the process can be improved, the input-output ratio can be improved, and the failure rate of the entire facility can be reduced by simplifying the facility.
Second, since the first robot is configured to perform the process of taking out the glass semi-finished product and putting it into the glass washer while the process of taking out the glass finished product from the glass forming machine and separating the lower mold and the upper mold from each other by the second robot and the third robot is performed, the speed of the process can be increased. It should be noted that the meaning of "performing a process" described above and to be described later is not limited to the case where the process is necessarily completed, but includes the case where a part of the process is performed.
Further, since the second robot is configured to perform the step of transferring the lower mold to the mold cleaning machine while the step of cleaning the glass semi-finished product by the glass cleaning machine, sucking the glass finished product by the third robot, and loading the glass finished product on the second cassette is performed, the speed of the step can be increased.
At the same time, the third robot is configured to perform the step of transferring the upper mold to the mold cleaning machine while the first robot sucks the glass semi-finished product to set the glass semi-finished product on the lower mold in a state where the lower mold is transferred by the second robot and returned to the preset position, so that the speed of the step can be increased.
As described above, at least a part of the processes for processing the glass semi-finished product, the glass finished product, the lower mold, and the upper mold are simultaneously performed in a state where the delay is minimized, so that the production speed of the glass having a three-dimensional shape can be increased.

Detailed Description
Next, a glass and mold transfer system and a method for producing a three-dimensional glass will be described in further detail with reference to the drawings.
In describing the embodiments disclosed herein, when it is judged that the detailed description of the related well-known technology may obscure the gist of the embodiments disclosed herein, a detailed description thereof will be omitted.
The drawings are only for the purpose of assisting understanding of the embodiments disclosed in the present specification and are not intended to limit the technical ideas disclosed in the present specification by the drawings, and should be understood to include all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.
In the following description, the singular expressions include the plural expressions unless the context clearly dictates otherwise.
In the present application, it should be understood that terms such as "including" or "having" are intended to indicate the presence of the features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and do not preclude the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.
Fig. 1 and 2 are a perspective view and a plan view showing a state in which a glass and mold transfer system 100 according to an embodiment of the present invention is butted against a glass molding machine 200.
As shown in fig. 1 and 2, the glass forming machine 200 is a device that forms and discharges a glass that is put into a predetermined shape. Glass as a molding object is put into the glass molding machine 200 in a state of being accommodated inside the mold M, and is discharged from the glass molding machine 200 after passing through a molding process.
For example, if a flat plate-shaped (two-dimensional shape) glass preform G1 is placed inside a mold M and the mold M is put into a glass molding machine 200, the mold M including a three-dimensional shaped glass preform G2 is discharged from the glass molding machine 200 after passing through a high-temperature heating step, a molding step, and a cooling step.
In order to continuously perform the above steps, a glass and mold transfer system 100 is connected to the glass molding machine 200.
That is, the glass and mold transfer system 100 is configured to load a glass into the glass molding machine 200 after the glass is placed in the mold M, and to load the molded glass after the mold M is removed from the glass molding machine 200, and to transfer the mold M so as to reuse the mold M in the loading.
The present invention is intended to provide a glass and mold transfer system 100 and a glass and mold M transfer process, which can further simplify the conventional glass and mold M transfer process, and will be described in detail below.
For reference, the directions shown in fig. 5 to 15 described later and the directions referred to in the description of the respective drawings are based on fig. 3. It is therefore apparent that the arrangement and movement principles of the various structures shown in fig. 5-15, and the principles of the glass and mold transfer system 100, can be readily understood if reference is made to fig. 3.
Fig. 3 is a plan view of the glass and mold transfer system 100 shown in fig. 2, and fig. 4 is an exploded perspective view of an example of a mold M used in the glass and mold transfer system 100 shown in fig. 3.
First, as shown in fig. 3, the glass and mold transfer system 100 includes a mold input unit 110, a mold discharge unit 120, a first cassette 181, a second cassette 182, a first robot 130, a second robot 140, a third robot 150, a glass washer 160, and a mold washer 170.
The mold loading unit 110 is a device for loading a mold M containing glass therein into the glass molding machine 200, and is connected to an inlet of the glass molding machine 200. Since the glass is glass before being molded by the glass molding machine 200, it can be understood as a glass semi-finished product G1.
The mold ejection unit 120 is a device that takes out the mold M ejected from the glass molding machine 200, and is connected to an outlet of the glass molding machine 200. Here, since the glass located inside the mold M is glass whose molding is completed by the glass molding machine 200, it can be understood as a glass product G2.
The first cassette 181 is a device for loading glass semi-finished products G1, and the second cassette 182 is a device for loading glass finished products G2. That is, the glass semi-finished product G1 taken out of the first cassette 181 is put into the glass forming machine 200, and the glass finished product G2 discharged from the glass forming machine 200 is loaded on the second cassette 182.
The glass semi-finished product G1 is processed by the first robot 130, the lower mold M1 is processed by the second robot 140, and the glass finished product G2 and the upper mold M2 are processed by the third robot 150. The specific functions of each robot 130, 140, 150 will be described below.
The glass washer 160 is a device formed in such a manner as to align and wash the glass semi-finished product G1, and is formed such that the glass semi-finished product G1 taken out of the first cassette 181 passes through the glass washer 160 before being set in the mold M.
The mold cleaning machine 170 is a device configured to clean the mold M discharged from the glass molding machine 200, and is configured such that the mold M passes through the mold cleaning machine 170 while being transferred to be loaded into the glass molding machine 200 again after the glass product G2 is taken out.
As shown in fig. 4, the mold M used in the glass and mold transfer system 100 shown in fig. 3 may be generally divided into two portions.
For example, the mold M may include a lower mold M1 for seating glass, and an upper mold M2 combined with the lower mold M1 in a manner of covering glass.
As shown, the lower mold M1 and the upper mold M2 may be respectively formed as a single mold M.
In addition, at least one of the lower mold M1 or the upper mold M2 may also be separated into a plurality of parts. For example, the lower mold M1 may include a bottom mold forming the bottom of the mold section, and a guide mold forming a side portion of the mold section and guiding the insertion of the upper mold M2. The bottom die and the guide die can be coupled to each other by a fastening member.
For reference, a mold for glass molding of the above-described structure is disclosed in the prior registered patent No. 10-1433072 (registered on 18 th 08/2014) of the present applicant.
Fig. 5 is a conceptual diagram illustrating an example of the mold inserting unit 110 shown in fig. 3.
As shown in fig. 5, the mold loading unit 110 is configured to horizontally transfer the mold M containing the glass therein and load the mold M into the glass molding machine 200. In order to realize the above transfer, a mode of pushing the mold M or a mode of moving a structure in which the mold M is placed may be adopted.
The mold loading unit 110 may include a plurality of mold loading units 111 and 112 for transferring the mold M in different directions. In the present drawing, there is shown a mold input unit 110 in which a first mold input portion 111 that transfers a mold M in a first direction in such a manner as to push the mold M and a second mold input portion 112 that transfers the mold M in a second direction perpendicular to the first direction in such a manner as to move a structure in which the mold M is placed are combined.
Specifically, the first mold input portion 111 includes a guide member 111a, a guide rail 111b, a moving member 111c, and a pushing member 111 d.
The guide member 111a is disposed at a position spaced apart from the table 101 to the upper side, and is elongated in a first direction (Y-axis direction in the drawing) to enable the set mold M to slidably move.
The guide member 111a is provided with protruding portions 111a 'on both sides thereof, and the protruding portions 111 a' extend in the first direction. By disposing the mold M between the two protrusions 111a ', the movement in the first direction is guided, and the separation to the outside of the protrusions 111 a' is prevented.
The guide rail 111b is arranged parallel to the guide member 111a, and is elongated in the first direction. The guide rail 111b may be disposed below the guide member 111a, and may be provided on the table 101, for example.
The moving member 111c is slidably provided on the guide rail 111 b. The moving member 111c is formed to be movable along a first direction which is an extending direction of the guide rail 111 b.
The moving member 111c may include a portion that is extended toward the guide member 111 a. In the present drawing, it is shown that a part of the moving member 111c is formed in such a manner as to be elongated in a second direction (Z-axis direction in the drawing) perpendicular to the first direction.
The pushing member 111d moves together with the moving member 111c by being provided on the moving member 111 c. The pushing member 111d is formed in such a manner as to perform a sliding movement in the first direction on the upper side of the guide member 111a, and is formed to push out the side surface of the mold M in the first direction when the mold M is set on the guide member 111 a.
In the present drawing, it is shown that the pushing member 111d is formed to be elongated in a third direction (X-axis direction in the drawing) perpendicular to both the first direction and the second direction so as to be movable in the first direction in a state of being overlapped with the guide member 111 a.
For reference, the pushing member 111d is moved in the first direction from the rear of the rotating unit 143, thereby pushing out the mold M seated on the seating portion 143a of the rotating unit 143 located at the first position P1. In other words, the pushing member 111d is formed to move onto the guide member 111a by pushing out the mold M set on the setting portion 143 a. Therefore, before the pushing member 111d pushes out the mold, the mold M is located on the seating portion 143a of the rotating unit 143 disposed at the first position P1 between the pushing member 111d and the guide member 111 a.
The second mold input portion 112 includes a guide rail 112a, a moving member 112b, a pushing piston 112c, and a pushing member 112 e.

The pushing member 112e is constituted in such a manner as to be capable of relative movement with respect to the mounting portion 112d by a change in length of the pushing piston 112c by being coupled at an end portion of the pushing piston 112 c. When the mold M is placed on the moving member 112b, it is formed in such a manner that if the length of the pushing piston 112c is extended, the pushing member 112e pushes out the mold M. Therefore, the mold M will be slidingly moved on the seating surface of the moving member 112 b. The above-described operation can be used when the mold M is finally put into the entrance of the glass forming machine 200.
The second mold input portion 112 may be provided with a mold detection sensor 112f for detecting whether or not the mold M is set on the moving member 112 b. As the mold detection sensor 112f, a proximity sensor, an illuminance sensor, or the like may be used.

The pushing member 121b moves together with the moving member 121c by being coupled to the moving member 121 c. The pushing member 121b is provided at an upper side of the guide member 121a in such a manner as to slidably move in the first direction, and is configured to push out a side of the mold M in the first direction when the mold M is seated on the guide member 121 a.
In the present drawing, it is shown that the pushing member 121b is formed to extend in a third direction (X-axis direction in the drawing) perpendicular to both the first direction and the second direction so as to be movable in the first direction in a state of being overlapped with the guide member 121 a.
For reference, the pushing member 121b is formed to push out the mold M until the mold M is seated to the seating portion 143a of the rotating unit 143 located at the second position P2. The rotation unit 143 moves in the first direction from the rear. In other words, the pushing member 121b is formed to push out the mold M set on the guide member 121a and move to the setting portion 143 a.

The cover 162 is configured to open the opening 161a only when the glass semi-finished product G1 is put into the glass washer body 161 or taken out from the glass washer body 161, and to cover the opening 161a otherwise.
In the drawing, a cover 162 is configured to open and close the opening 161a so as to slide on the upper surface of the glass washer body 161.
Therefore, a slide rail 165 is provided on the upper surface of the glass washer body 161. The slide rail 165 includes a guide member 165a and a connecting member 165 b.
The guide member 165a is formed to be elongated along the sliding direction of the cover 162. For example, the guide member 165a may be disposed parallel to one side of the opening 161 a.
The connecting member 165b is coupled to the guide member 165a so as to be movable in the extending direction of the guide member 165 a. Further, the cover 162 is coupled to the connecting member 165b, so that the cover 162 can be moved together when the connecting member 165b moves.

The support 163a is provided so as to face the opening 161a inside the glass washer body 161, and is formed to support one surface of the set glass semi-finished product G1.
In the drawing, the glass washer body 161 is provided with at least three or more support rods at the bottom thereof to support one surface of the glass semi-finished product G1. When the support portion 163a is formed as a rounded support rod as described above, there is an advantage that the contact area can be reduced by bringing the support rod into point contact with one surface of the glass semi-finished product G1.
The glass washer 160 may include a fiber sensor (not shown) for detecting whether or not the glass semi-finished product G1 is set on the support 163 a. The second alignment portion 163b ″ described later moves when the seating of the glass semi-finished product G1 is detected by the above-described fiber sensor.
The first alignment portion 163 b' is provided in a state of being fixed to a position provided in advance, and is formed to support a side edge of the glass semi-finished product G1 placed on the support portion 163 a.
In the drawing, at least one first alignment portion 163b 'is provided at each of positions corresponding to the first and second sides so that the first alignment portion 163 b' supports the first side and the second side of the glass intermediate product G1, which intersect each other.
The second alignment portion 163b ″ is in contact with the other side of the glass preform G1, and is formed so as to be movable closer to the first alignment portion 163 b' via the glass preform G1.

In this process, the second alignment portions 163b ″ come into contact with the third and fourth sides of the glass semi-finished product G1, respectively. Thereafter, the second alignment portion 163b ″ is moved to be close to the first alignment portion 163b 'while pushing the glass semi-finished product G1, and when the glass semi-finished product G1 comes into contact with the first alignment portion 163 b', the movement of the second alignment portion 163b ″ is stopped.
The movement and stop of the second alignment portion 163b ″ can be controlled based on the detection value detected by the sensor.
For example, a pressure detection sensor (not shown) for detecting the applied pressure may be provided in the first alignment portion 163 b' or the second alignment portion 163b ″. When the alignment of the glass semi-finished product G1 is completed, the pressure applied to the first alignment portion 163 b' or the second alignment portion 163b ″ may exceed a predetermined pressure. The second alignment portion 163b ″ may be formed to stop moving when the pressure detected by the pressure detection sensor exceeds a predetermined pressure.
The ion blower 164 is formed to inject ionized air into the glass washer body 161. The dust of the glass intermediate product G1 can be removed by ejecting the ionized air, and the dust can be prevented from being adsorbed by removing the static electricity of the glass intermediate product G1.
In this figure, it is shown that an ion blower 164 is provided on at least one side surface of the glass washer body 161.
As described above, the glass washer 160 is formed to align and wash the glass semi-finished product G1. The alignment and the cleaning of the glass semi-finished product G1 may be performed simultaneously, or the alignment may be performed first and then the cleaning may be performed.

Therefore, the mold M ejected from the glass molding machine 200 can be placed on the transfer unit 192.
The transfer unit 192 may be formed to move downward at a predetermined pitch every time the mold M is loaded.
The guide bars 193 are formed outside the transfer unit 192 so as to be extended in the vertical direction at a plurality of positions. That is, the guide bars 193 are formed so as to prevent the separation of the molds M by being disposed at the outer side of the molds M loaded on the transfer unit 192.

Thereby, the production speed of the glass having a three-dimensional shape can be increased.
First, while the process of taking out the glass product G2 from the glass molding machine 200 by the mold discharge unit 120 and separating the lower mold M1 and the upper mold M2 from each other by the second robot 140 and the third robot 150 is performed, the process of taking out the glass semi-product G1 by the first robot 130 and putting it into the glass cleaning machine 160 is performed.
It should be noted that the meaning of "performing a process" described above and to be described later is not limited to the case where the process is necessarily completed, but includes the case where a part of the process is performed.
Next, while the process of cleaning the glass semi-finished product G1 by the glass cleaning machine 160, adsorbing the glass finished product G2 by the third robot 150 and loading the glass finished product on the second cassette 182 is performed, the process of transferring the lower mold M1 to the mold cleaning machine 170 by the second robot 140 is performed.
Thereafter, while the process of placing the glass intermediate product G1 on the lower mold M1 by causing the first robot 130 to suck the glass intermediate product G1 is performed in a state where the lower mold M1 is transferred by the second robot 140 and returned to the preset position (i.e., the first position P1), the process of transferring the upper mold M2 to the mold cleaning machine 170 by the third robot 150 is performed.
Next, while the process in which the third robot 150 places the upper mold M2 so as to cover the lower mold M1 (i.e., moves to the first position P1) is being performed, the process in which the first robot 130 moves to a preset position (initial position) is performed.
Thereafter, while the step of inputting the glass semi-finished product G1 into the glass molding machine 200 by the mold input unit 110 is being performed, the step of moving the second robot 140 to a predetermined position (initial position) after the third robot 150 has moved to a predetermined position (initial position) is performed.
From the viewpoint of the processing of the glass semi-finished product G1 and the glass finished product G2 and the processing of the mold M, the above-mentioned processes can be arranged as follows:
the glass and mold M transfer step includes a step of taking out the plate-like glass semi-finished product G1 from the first cassette 181, washing the same with the glass washer 160, and then feeding the same to the glass forming machine 200; a step of loading the glass product G2, which has been molded into a three-dimensional shape, on the second cassette 182 by removing it from the glass molding machine 200; and a step of transferring the lower mold M1 and the upper mold M2 taken out of the glass molding machine 200 to be reused in the above-described charging step. By the above transfer, the lower mold M1 and the upper mold M2 are moved from the second position P2 to the first position P1.
The step of removing the second cartridge 182 to load the second cartridge includes: a first step of relatively moving either one of the lower mold M1 and the upper mold M2, and a second step of sucking the glass product G2 set on the lower mold M1 and feeding the glass product G to the second cassette 182.
In the first step, the upper mold M2 may be clamped and moved upward in a state where the lower mold M1 is fixed.
A blower 106 (see fig. 3) for blowing air into a gap between the lower mold M1 and the upper mold M2 may be provided at a position adjacent to the second position P2. The blower 106 ejects air when one of the lower mold M1 and the upper mold M2 moves relatively, so that the glass is separated when it adheres to the upper mold M2.
The blower 106 may be configured so that its position can be arbitrarily adjusted. For this purpose, the blower 106 may have a multi-joint structure that can be adjusted in shape in three dimensions.
The second step includes: a step of lowering the sucked glass product G2 to a predetermined position to be received in the second cassette 182; a step of releasing the adsorption of the glass product G2; and a step of horizontally moving the second chuck 182 at a predetermined pitch (movement in the Y-axis direction in fig. 14). Accordingly, the taking-out unit 154 of the third robot 150 only has to lower the glass product G2 to a specific position, and thus the structure of the third robot 150 can be simplified and the accuracy of the process can be improved.
During the execution of the above second step, the glass semi-finished product G1 is cleaned by the glass cleaner 160, and the lower mold M1 is cleaned by the mold cleaner 170.
In the step of transferring for reuse, the lower mold M1 and the upper mold M2 are moved apart from each other, and are sequentially cleaned by the single mold cleaning machine 170 in the process of the movement.
That is, the step of transferring for reuse includes: a step of cleaning the lower mold M1 using the mold cleaner 170, and a B step of cleaning the upper mold M2 using the mold cleaner 170.
The lower mold M1 is formed to be rotated by 180 degrees before the above-described a step and to be rotated again by 180 degrees after the above-described a step. The rotation direction after the step a may be opposite to the rotation direction before the step a.
The mold part of the lower mold M1 is cleaned in such a manner as to pass over the upper side of the mold cleaner 170 while the lower mold M1 is horizontally moved (moved in the X-axis direction in fig. 8) in a state of being rotated by 180 degrees before the above-described a step.
A foreign matter dust collection unit 105 may be provided between the second position P2 and the mold cleaning machine 170 to collect foreign matters falling from the mold part while the lower mold M1 is rotated before entering the mold cleaning machine 170.
The above-mentioned B step is carried out during the setting on the lower mold M1 at the first position P1 after the glass semi-finished product G1, which has been aligned and cleaned, is sucked to complete the cleaning.
The movement path of the upper mold M2 and the movement path of the lower mold M1 overlap in the vertical direction (Z-axis direction in fig. 3). However, the lower mold M1 and the upper mold M2 are formed to move with a time difference therebetween so as not to affect the moving path therebetween. Therefore, while the lower mold M1 and the upper mold M2 are sequentially transferred to return to the predetermined positions, the lower mold M1 and the upper mold M2 are sequentially cleaned by the single mold cleaner 170.
