Description

Technical Field

[0001] The utility model relates to the technical field of glass storage equipment, in particular to a new gantry storage equipment. Background Technique

[0002] Glass is an amorphous inorganic non-metallic material, generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added additionally. Its main components are silicon dioxide and other oxides.

[0003] In the existing technology, at present, for glass warehouses, traveling cranes are mainly used in cooperation with tooling fixtures to manually operate the warehousing, outbound and sorting of whole packages or single pieces of glass. Since the glass size in glass warehouses is generally 6 meters long * 3.3 meters wide, and the weight of each package of glass is about 3 - 4 tons, this manual operation method has low safety, low efficiency, and high technical requirements for operators.

[0004] Under this current situation, how to liberate workers from the dangerous operation environment, the market has always called for the development of gantry storage equipment with automatic operation capabilities. Some enterprises in the market have also tried to conduct research and development. However, due to factors such as the large moving distance of the hoisting equipment for handling glass raw material packages in the glass raw material warehouse, the large weight of the spreader + the whole package of glass raw materials (a large weight means a large inertia), and the different varieties and specifications of glass in the warehouse, it is extremely difficult to fully automate a series of operation processes such as the automatic positioning, automatic grasping, automatic handling, and automatic placement of the gantry spreader. It not only requires complete hardware facilities but also the synchronous improvement of management software and control software.

[0005] In the existing technology, such as the Chinese patent with the publication number CN 117262569 A, it discloses a gantry storage equipment, including a double-girder traveling crane, a glass rack, and a gantry spreader. The double-girder traveling crane moves horizontally and longitudinally above the glass rack, and the gantry spreader is installed below the double-girder traveling crane for transporting whole packages of glass or single pieces of glass. A traveling trolley connected to the gantry spreader is arranged on the double-girder traveling crane, and the gantry spreader includes a slewing bearing, a fixing component, a lifting component, a flipping component, a flipping fork component, a backrest support component, a hook component, an electric push rod component, and a lift component.

[0006] The above-mentioned existing technical solutions have the following defects: First, its flipping fork component cannot adjust the extending length according to the thickness of the glass. In this way, when glass packages with different thicknesses are placed on the glass rack, when grasping the outer glass package, interference with the glass plates placed inside will occur, which will cause danger.

[0007] Second, when the gantry spreader grabs the glass, only the tipping of the upper part of the glass is restricted. However, the lateral dimension of the glass is very large, and there is no restraint during the overall handling process. High-speed handling of the glass will also pose risks.

[0008] Third, spacer bars are placed between the glass packages for convenient grasping and placement. These spacer bars need to remain in place during handling. If the spacer bars cannot be kept in the placement position during handling, manual entry into the site is required for placement, which is time-consuming, laborious, and unsafe.

[0009] Fourth, the backrest support assembly is used to support the grabbed glass. If the backrest support assembly cannot ensure a necessary parallel relationship with the glass plate surface, the support effect of the backrest support assembly on the glass will be greatly reduced. Thus, it is very important to detect whether there is a roughly parallel relationship between them and how to adjust when there is a non-parallel relationship.

[0010] Fifth, during the process of the gantry spreader performing the operations of grabbing and placing the glass, a series of actions need to be completed. The execution of this series of actions requires a certain sequence logic relationship. Only by executing according to the correct logic sequence relationship can the equipment exert its due efficacy.

[0011] In summary, the problems of how to achieve precise grasping, rapid and precise positioning, and precise placement of the glass during the process of the gantry spreader performing the operations of grabbing and placing the glass urgently need to be solved. Summary of the Invention

When the backrest support assembly 3-11 moves towards the glass package on the glass rack 2, it can real-time feedback the mutual position relationship between the backrest support assembly 3-11 and the glass package, and determine the adjustment method of the mutual position relationship between the backrest support assembly 3-11 and the glass package according to the actual measurement data of the four sets of linear displacement sensor assemblies 3-12.

[0072] Operation process:

[0073] Refer to Figure 3 And Figure 4 , first, the double-beam crane 1 is positioned at the specified safe position on the rack where the glass package needs to be transported according to the system instructions. The lifting assembly 3-04 descends to a safe height, making the upper surface of the fork of the bottom fork assembly 3-06 lower than the bottom surface of the glass.

[0074] By extending the electric push rods of the top backrest servo electric cylinder flipping assemblies 3-05 arranged on the left and right sides at the top of the backrest support assembly, the glass package support surface of the backrest support assembly 3-11 is adjusted, that is, the backrest support longitudinal beam is in a position state approximately parallel to the glass package placed on the glass rack.

[0075] The bottom fork assembly 3-06 extends a corresponding length according to the thickness dimension of the glass sheet package to be carried.

[0076] The left and right hook assemblies 3-08 at the top move downward along the backrest support assembly 3-11 to a specified height according to the height of the glass package.

[0077] The clamping mechanism assemblies 3-07 on both sides extend the spacer support assemblies 3-10 installed on the left and right respectively to a predetermined position according to the width of the glass to be carried through the servo-driven guiding mechanism installed on the clamping mechanism assemblies 3-07 on both sides.

[0078] The left and right hook assemblies 3-09 at the waist installed at the ends of the clamping mechanism assemblies 3-07 on both sides extend to a predetermined position according to the thickness of the glass package through the servo electric cylinders installed on the left and right hook assemblies 3-09 at the waist.

[0079] The traveling trolley 1-01 moves to gradually approach the glass package with the gantry spreader. At this time, the four linear displacement sensor assemblies 3-12 on both sides of the left and right backrest support longitudinal beams installed on the backrest support assembly 3-11, when the backrest support assembly 3-11 moves towards the glass package on the glass rack, will real-time feedback the relative position relationship between the backrest support assembly 3-11 and the glass package. When the actual measurement data of any one of the linear displacement sensor assemblies 3-12 reaches a certain set value, the traveling trolley 1-01 stops running.

[0080] After the traveling trolley 1-01 stops running, the electrical control system will determine the adjustment method of the relative position relationship between the backrest support assembly 3-11 and the glass package according to the actual measurement data of the four linear displacement sensor assemblies 3-12.

[0081] According to the actual measurement data of the four linear displacement sensor assemblies 3-12 when the backrest support assembly 3-11 moves towards the glass package on the glass rack, when the values on the left and right sides differ greatly, the large gear ring installed on the hoisting assembly 3-03 is reversely driven by the driving pinion installed on the fixed assembly 3-01, driving the entire gantry spreader to rotate in the reverse direction by a suitable angle until the measured values of the linear displacement sensor assemblies 3-12 on both sides are roughly equal. When the value difference is less than a certain set value, it is considered that the backrest support assembly 3-11 is roughly parallel to the glass package in the horizontal direction.

[0082] According to the actual measurement data of the four sets of linear displacement sensor assemblies 3-12 when the backrest support assembly 3-11 moves towards the glass package on the glass rack, when the values of the upper and lower groups differ significantly, the telescopic length of the electric push rod of the servo electric cylinder flipping assembly 3-05 for the backrest installed at the top of the backrest support assembly 3-11 is adjusted, driving the backrest support assembly 3-11 to rotate reversely by an appropriate angle around the hinge axis connected to the bottom of the lifting assembly 3-04, so that the measured values of the upper and lower groups of linear displacement sensor assemblies 3-12 are approximately equal. When the value difference is less than a certain set value, it is considered that the backrest support assembly 3-11 is approximately parallel to the glass package longitudinally.

[0083] The four sets of linear displacement sensors are used to measure whether the backrest support assembly 3-11 is parallel to the glass in the vertical and horizontal directions and the corresponding adjustment methods are described in detail as follows:

[0084] Four sets of linear displacement sensor assemblies 3-12 are installed at appropriate heights and widths on both sides of the left and right backrest support longitudinal beams of the backrest support assembly 3-11, forming four measurement points in the vertical and horizontal directions. When the backrest support assembly 3-11 moves towards the glass package on the glass rack 2, it can real-time feedback the relative position relationship between the backrest support assembly 3-11 and the glass package, and judge the relative position relationship between the backrest support assembly 3-11 and the glass package according to the actual measurement data of the four sets of linear displacement sensor assemblies 3-12, and decide what adjustment method to take.

[0085] Refer to Figure 5 , points A, B, C, and D are the layout positions of the four linear displacement sensors, Figure 5 shows the dimensional position relationship between the four linear displacement sensors and the original glass sheet when the gantry crane 3 approaches the glass package.

[0086] Refer to Figure 6 , when the backrest support assembly 3-11 of the gantry crane 3 has the position relationship shown in the figure with the glass plate, that is, when point A is slightly farther from the glass than point B, we let the large gear ring installed on the lifting assembly 3-03 rotate clockwise by a certain angle driven by the driving small gear, so that the readings of the linear displacement sensors at points A and B are approximately close, that is, it is considered that the horizontal adjustment is in place. It is also possible to compare the sensor values of points C and D. All of this is completed instantaneously by the computer control system.

[0087] Refer to Figure 7, when the backrest support assembly 3-11 of the gantry spreader 3 has the positional relationship shown in the figure with the glass plate, that is, when point B is slightly farther from the glass than point A, we let the large gear ring installed on the lifting assembly 3-03 rotate counterclockwise by a certain angle driven by the driving pinion, so that the readings of the linear displacement sensors at points A and B are approximately close, that is, it is considered that the lateral adjustment is in place. We can also compare the sensor values at points C and D. All of this is completed instantaneously by the computer control system.

[0088] Refer to Figure 8 , when looking from the side of the glass package, the ideal relationship between the gantry spreader 3 and the glass should be the state shown in this figure. However, due to the change in the positional relationship during the glass placement, it is very difficult for the gantry spreader 3 to have equal vertical distances from the glass surface at points A and C or points B and D, and the following two states will occur:

[0089] Refer to Figure 9 , when there is a large gap at the upper part and a small gap at the lower part longitudinally between the backrest support longitudinal beam in the backrest support assembly 3-11 and the glass, we can make the backrest support assembly 3-11 rotate counterclockwise around point O by making the extended length of the upper electric push rod longer. The specific rotation angle can be realized by the electric push rod extending an appropriate length under the control of the computer control system.

[0090] Refer to Figure 10 , when there is a small gap at the upper part and a large gap at the lower part longitudinally between the backrest support longitudinal beam in the backrest support assembly 3-11 and the glass, we can make the backrest support assembly 3-11 rotate clockwise around point O by making the extended length of the upper electric push rod shorter. The specific rotation angle can be realized by the electric push rod retracting an appropriate length under the control of the computer control system.

[0091] After the above adjustment actions are completed under the control of the electrical system, the lifting assembly 3-04 makes a lifting action upward until the forks in the bottom fork assembly 3-06 touch the bottom of the glass package. At this time, the sensor installed on the bottom fork assembly 3-06 sends out a signal indicating that the lifting is in place, and the lifting assembly 3-04 stops the lifting action.

[0092] Then, the fork extension in-place action of the bottom fork assembly 3-06 in the gantry spreader 3, the two-side clamping mechanism assembly 3-07 reaching the final extended position from the predetermined extended position, the hook extension in-place actions of the top left and right hook assemblies 3-08, and the hook extension in-place actions of the waist left and right hook assemblies 3-09 are all implemented with the help of the sensors they carry.

[0093] For the bottom fork assembly in the gantry spreader, the forks reaching the final extended position from the predetermined extended position, the clamping mechanism assemblies on both sides reaching the final extended position from the predetermined extended position, the hook assemblies on the left and right sides at the top reaching the final extended position from the predetermined extended position, and the hook assemblies on the left and right sides at the waist reaching the final extended position from the predetermined extended position are all implemented when the backrest support assembly is adjusted to be roughly parallel to the glass package both longitudinally and horizontally.

[0094] After the fork extension in place action of the bottom fork assembly 3-06 in the gantry spreader 3, the clamping mechanism assemblies 3-07 on both sides reaching the final extended position from the predetermined extended position, the extension in place action of the hook assemblies 3-08 on the left and right sides at the top, and the extension in place action of the hook assemblies 3-09 on the left and right sides at the waist are all completed, the hooks of the hook assemblies on the left and right sides at the top, driven by the electric cylinders, pull back the top hooks to fix the top of the glass package on the backrest longitudinal beam. The hooks of the hook assemblies 3-09 on the left and right sides at the waist, driven by the electric cylinders, pull back the waist hooks to clamp the waist of the glass package.

[0095] At this time, the backrest support assembly 3-11 has already abutted against the back of the glass. Next, the electric push rod connecting the top of the backrest support assembly 3-11 and the lifting assembly 3-04 starts to retract, driving the entire backrest support assembly 3-11 to rotate around the bottom rotation axis of the lifting assembly 3-04 until the backrest support assembly 3-11 changes from the forward inclination state to the backward inclination state of 3° with respect to the vertical plane, and the glass sheet package disengages from the glass rack, completing the sheet picking action of grasping the entire glass sheet package. Next, the lifting assembly 3-04 of the gantry spreader 3 completes the upward lifting action of the entire glass package. Then, the traveling trolley moves the gantry spreader to a designated safe position at a certain distance from the glass rack.

[0096] Then, the double-girder overhead crane 1 starts to move rapidly as a whole from this safe position until it reaches the designated safe position of the next glass rack where the glass raw material packages need to be placed. The overhead crane trolley continues to move with the gantry lifting tool until the sensors on the forklift assembly start to detect the working position. The lifting assembly 3-04 drives the glass package to start descending to the predetermined position. The electric push rod connecting the top of the backrest support assembly 3-11 to the lifting assembly 3-04 starts to slowly extend to adjust the glass package on the gantry lifting tool 3 to be parallel to the glass rack. At this time, the back of the glass is already supported on the glass rack. Next, the hooks of the hook assemblies 3-08 on the left and right sides at the top first extend a certain distance and then start to rise to disengage from the top of the glass package. The hooks of the hook assemblies 3-09 on the left and right sides at the waist also first extend a certain distance and then start to open. After opening, they retract to the home position of the electric cylinder. Then, the hook assemblies 3-09 on the left and right sides at the waist are driven by the clamping mechanism assemblies 3-07 on both sides to retract to the original position. Then, the entire lifting assembly 3-04 descends, and the entire gantry lifting tool 3 starts to disengage from the glass package, completing the glass sheet placing operation for the entire package of glass. Next, the overhead crane trolley moves the gantry lifting tool without load to the designated safe position at a certain distance from the glass rack or returns to the designated starting origin in the original glass storage warehouse to wait for the next handling operation instruction.

[0097] The gantry lifting tool 3 is equipped with suction cups and / or vacuum pumping equipment. Since the handling of the entire package of glass raw material packages can be completed automatically or manually from one glass rack 2 to another glass rack 2, any person with similar work experience can, on this basis, transform it into a lifting tool for single-pane glass by adding suction cups and vacuum pumping equipment. Therefore, any work on transforming it into a lifting tool for single-pane glass based on this falls within the protection scope of this patent.

[0098] The new gantry storage equipment is used to handle single-package boxed glass raw material packages, two or more boxed glass raw material packages. Through appropriate transformation, it can not only handle single-package boxed glass raw material packages but also be used for the handling of two or more boxed glass raw material packages. Therefore, any work on transforming it for the handling of two or more boxed glass raw material packages based on this will fall within the protection scope of this patent.

[0099] The guide rails for the longitudinal movement of the double-beam crane 1 can be laid on the ground or on the columns on both sides of the factory building, and can be erected through the supporting mechanism close to the top of the factory building columns. The steel rails laid on the ground (commonly known as ground rails), the gantry crane with support legs moves longitudinally along the steel rails (ground rails) through the traveling mechanism; the steel rails laid on the supporting mechanism of the factory building columns (commonly known as overhead rails), the traveling mechanisms set at both ends of the double crossbeams of the overhead crane are directly connected across them, and move longitudinally along the steel rails (overhead rails). Alternatively, the longitudinal movement of the storage equipment can be accomplished through a truss structure. Therefore, any simple labor to circumvent the claims of this patent by changing the longitudinal movement mode of the storage equipment on this basis will fall within the scope of protection of this patent.

[0100] The implementation principle of the utility model is as follows: the utility model discloses a novel gantry storage equipment, which, on the basis of the prior art, realizes the adjustable function of the fork extension length by adding a fork extension length adjustment mechanism on the bottom fork assembly 3-06, and adds corresponding sensor equipment on the head and side of the fork, so that the extension length can be automatically adjusted according to the result of on-site detection; by adding clamping mechanism components on both sides of the backrest support component 3-11 to realize the clamping action on the glass waist with a large lateral dimension, so as to ensure the lateral stability of the glass during the transportation process; by arranging a spacer bar component on the clamping mechanism, which is synchronously extended with the clamping mechanism component, the glass spacer bar is kept in place.

[0101] By setting up a linear displacement sensor component 3-12, it is possible to detect whether the backrest support component 3-11 maintains the necessary parallel relationship with the glass plate surface, and the control system makes corresponding adjustments through corresponding adjustment methods according to the detection results to ensure that there is a rough parallel relationship between the two, and to ensure that the glass is reliably supported on the backrest support component 3-11.

[0102] In the process of the gantry crane 3 grabbing and placing the glass, the above series of actions need to be completed. The execution of this series of actions requires a certain logical relationship. Through the careful design of the control system, the gantry storage equipment can accurately complete this series of actions according to the set logical relationship, thereby realizing the precise grabbing, fast and accurate positioning, and precise placement of the glass.

[0103] The purpose of setting the above series of components and actions is to achieve a fully fixed state after the glass package is grabbed by the gantry crane 3, with a load on the bottom (the bottom fork assembly 3-06 bears the full weight of the glass), a backrest (leaning on the backrest support longitudinal beam of the backrest support assembly 3-11), a hook on the top to pull it inward, and hooks on both sides to clamp it around the waist, so as to fix the glass package and the gantry crane 3 tightly together, thereby ensuring the safety of the glass during the transportation process.

[0104] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
