Description

Technical Field

[0001] The invention relates to the technical field of glass production and manufacturing, and in particular to a material unloading system for glass processing. Background Art

[0002] In the process of glass production, it is often necessary to transfer between various processes. How to transfer the glass pieces to the next production line smoothly and quickly is one of the issues that glass producers need to focus on. Since the glass blanks used to make optical glass are often large and heavy, and the edges of the glass are brittle, the glass is easily vibrated or desorbed during processing and transportation, causing edge breakage, shedding or shattering, which seriously affects the normal operation of the glass production line.

[0003] In addition, the surface of glass products is easily affected by the environment and debris is attached during processing and transportation. When glass products are stacked in batches for transportation, they usually need to be wrapped and tightened to prevent the glass products from falling off. However, when optical glass with debris attached to the surface is subjected to a certain stress, its surface is often affected by friction and worn, and even difficult to use. For this reason, we have proposed a feeding system for glass processing. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a material feeding system for glass processing.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: The present invention provides a material unloading system for glass processing, comprising: a base with a square opening in the middle; a material bin fixedly connected to the top of the base for centrally placing glass to be processed; a material fork mechanism fixed to the top of the base, the material fork mechanism comprising two sets of fork arm assemblies arranged opposite to each other, a first working position is arranged above the fork arm assemblies along the inner side of the material bin; a guide mechanism having two sets of guide seats arranged in parallel, the guide seats are fixed to the top of the base by locking members and are used for guiding the glass during movement, a second working position is arranged above the guide mechanism along the inner side of the material bin, and a third working position and a material unloading position are arranged in sequence and in parallel with the second working position above the guide seats; a material pushing mechanism fixed to the bottom surface of the base for moving the glass from the first working position downward to the second working position; and a translation mechanism fixed to the top of the base for translationally moving the glass from the second working position to the third working position and the material unloading position.

[0006] As a preferred technical solution of the present invention, the silo includes four symmetrically arranged support rods, and guide plates for limiting the side edges of the glass are fixedly installed on both sides of the support rods.

[0008] As a preferred technical solution of the present invention, the guide seat includes a square bottom plate fixedly connected to the upper surface of the base and an L-shaped baffle fixedly connected to the upper part of the square bottom plate.

[0009] As a preferred technical solution of the present invention, the pushing mechanism includes a pushing cylinder, two side plates for fixing the pushing cylinder, a support plate fixed to the top of the pushing cylinder, and four symmetrically arranged guide rods fixed to the upper surface of the support plate. The ends of the two guide rods are fixed with brackets for supporting the glass to move down to the second working position.

[0010] As a preferred technical solution of the present invention, the translation mechanism includes a linear slide rail fixed to the top of the base, a linear motor and a pushing assembly for pushing the glass to move horizontally.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The glass at the first working position is transported to the second working position by the pushing mechanism, and the glass at the second working position is transported to the unloading position by the translation mechanism. When the transport mechanism transports the empty tray to the second working position, the pushing mechanism moves the glass above the first working position in the silo down to the first working position. The above actions are repeated to transport the stacked glass in the silo to the unloading position in order for subsequent processing and use, thus realizing the orderly and automatic unloading of glass and improving the unloading efficiency and practicality. 2.

DETAILED DESCRIPTION

[0014] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0015] In the drawings, the same reference numerals all refer to the same components.

[0016] like Figure 1-13 As shown, the present invention provides a material unloading system for glass processing, comprising: a base 1, a silo 2, a fork mechanism 3, a guide mechanism 4, a push mechanism 6 and a translation mechanism 7. The present invention transports the glass products to be processed stacked in the silo 2 to the set unloading position one by one in an orderly manner, so as to facilitate the subsequent processing and use: In this embodiment, the base 1 is a square flat plate, and a square opening is provided in the middle of the base 1 for avoiding the movement trajectory of the lifting cylinder 57 on the translation mechanism 7. A silo 2 for centrally stacking and placing the glass to be processed is provided at one end of the base 1. The silo 2 is fastened to the upper surface of the base 1 by threaded connection. The silo 2 is arranged perpendicular to the base 1 and plays a guiding role when the glass moves downward. like Figure 2-6 As shown, the fork mechanism 3 is fixed on the upper surface of the base 1, and the fork mechanism 3 includes two sets of fork arm assemblies 21 arranged opposite to each other, and the two sets of fork arm assemblies are respectively arranged on both sides of the silo 2. When the glass is lowered, the upper push plate 28 and the lower push plate 29 of the fork arm assembly 21 can be retracted from the silo, and a first working position for initial positioning of the glass is provided above the fork arm assembly 21 along the inner side of the silo 2. In the initial state, the upper push plate 28 and the lower push plate 29 of the fork arm assembly 21 extend into the silo and contact the lower surface of the glass, so as to support and fix the glass at the first working position; like Figure 3 As shown, the guide mechanism 4 has two sets of parallel guide seats 5, which are fixed to the upper surface of the base 1 by threaded fasteners, and the inner side of the guide seat 5 is slidably connected with the two side surfaces of the glass, which is used for guiding the glass during horizontal movement, and the upper surface of the guide seat 5 is in contact with the lower surface of the glass, which is used for carrying the glass moving in parallel. A second working position is provided at the bottom layer along the inner side of the silo 2 above the guide mechanism 4, and a third working position and a material discharge position are provided in sequence on the surface of the guide seat 5 parallel to the second working position. When the glass is translated, it will pass through the second working position, the third working position, and the material discharge position in sequence; like Figure 4 As shown, the pushing mechanism 6 is fixed to the bottom surface of the base 1 by threaded connection, and the pushing mechanism 6 is vertically arranged directly below the silo 2. When the glass needs to be unloaded, the pushing mechanism 6 moves vertically downward to support the glass to move downward from the first working position to the second working position; like Figure 1 As shown, the bottom of the translation mechanism 7 is fixed on the top of the base 1 by threaded connection. The translation mechanism 7 is arranged parallel to the guide mechanism 4 and is used to push the glass to translate from the second working position to the third working position and the unloading position in sequence.

[0017] The use of the present invention is as follows: 1. If Figure 1 As shown, the glass stack is placed in the silo 2. When unloading is required, the pushing cylinder 41 in the pushing mechanism 6 drives the bracket 45 to move upward and contact the bottom surface of the glass at the bottom of the silo; then the push rod of the fork arm cylinder 23 in the fork arm assembly 21 contracts, driving the upper push plate 28 and the lower push plate 29 to move toward the outside of the silo, when the upper push plate 28 and the lower push plate 29 are completely pulled out from the bottom of the glass; the push rod of the pushing cylinder 41 contracts, driving the first piece of glass at the first working position to move down to the second working position, at which time the first piece of glass is on the square bottom plate 31 of the guide seat 5; then the push rod of the fork arm cylinder 23 extends out, driving the upper push plate 28 and the lower push plate 29 to extend into the silo, carrying the second piece of glass above the first piece of glass to fall to the first working position.

[0018] 2. The push rod of the lifting cylinder 56 in the translation mechanism 7 rises, driving the blocking plate 57 and the second push plate 58 to rise. At this time, the first piece of glass is located between the first push plate 54 and the blocking plate 57. Then the linear motor 52 starts to move, driving the slider on the linear slide rail 51 to start moving, thereby driving the first push plate 54 and the blocking plate 57 connected thereto to move horizontally, thereby transporting the glass at the second working position to the third working position.

[0019] 3. Repeat the above actions. Under the action of the translation mechanism 7, the second push plate 58 in the translation mechanism 7 pushes the glass in the third working position to the unloading position on the rightmost side of the guide seat 5. This cycle is repeated to realize the orderly transportation of the stacked glasses in the silo 2 to the unloading position. The materials can be unloaded automatically and orderly, thereby improving the unloading efficiency.

[0020] Further, such as Figure 1-3 As shown, the silo 2 includes four symmetrically arranged support rods 11, the bottom ends of the four support rods 11 are vertically fixed to the upper surface of the base 1 by welding, and guide plates 12 for limiting the edge of the glass are fixedly installed on both sides of the support rods 11. In the present embodiment, the guide plate 12 is composed of two parallel sheet metal parts, one of which is a flat plate in contact with the long side of the glass, and the other sheet metal part is L-shaped in contact with the short side of the glass. The guide plate 12 forms a quadrilateral, which completely limits the four sides of the glass and plays a limiting function when the glass moves down.

[0021] Further, such as Figure 4-7As shown, in this embodiment, the fork arm assembly 21 includes a gate-shaped bracket 22, the vertical rod of the gate-shaped bracket 22 is fixed to the top of the base 1 by threaded connection, and the cross bar of the gate-shaped bracket 22 is connected to the vertical rod by threaded connection; two fork arm cylinders 23 are fixedly arranged in the middle of the gate-shaped bracket 22, and the two fork arm cylinders 23 are symmetrically arranged along the cross bar of the gate-shaped bracket 22; four guide shaft supports 24 are arranged on the side of the gate-shaped bracket 22 through its cross bar; an upper connecting plate 25 and a lower connecting plate 26 are movably connected to the fork arm cylinder 23, wherein a semicircular notch is provided in the middle of the upper connecting plate 25 and is movably connected to the protruding end of the upper fork arm cylinder by a floating ball head, and a semicircular notch is provided in the middle of the lower connecting plate 26 and is movably connected to the protruding end of the lower fork arm cylinder by a floating ball head. The head is movably connected; two guide shafts 27 are respectively threadedly fixedly connected at both ends of the upper connecting plate 25 and the lower connecting plate 26, and the guide shaft 27 is slidably connected to the guide shaft support 24 to transmit the thrust of the fork arm cylinder 23. An upper push plate 28 and a lower push plate 29 are threadedly connected at the other end of the guide shaft 27. The upper push plate 28 and the lower push plate 29 are both L-shaped structures. The L-shaped structure is used to support the bottom and side surfaces of the stacked glass. When the glass is stacked, the upper push plates 28 and the lower push plates 29 on both sides of the silo are driven by the fork arm cylinder 23 to fully extend into the silo to support and position all the stacked glass. When unloading is required, the push rod of the fork arm cylinder 23 is retracted, and the upper push plates 28 and the lower push plates 29 are withdrawn from the silo to facilitate the glass to descend to the second working position.

[0022] Further, such as Figure 1-3 As shown, the guide seat 5 includes a square bottom plate 31 and an L-shaped baffle 32, wherein the bottom surface of the square bottom plate 31 is fixedly connected to the upper surface of the base 1 by threaded connection, and the L-shaped baffle 32 is fixedly connected to the upper part of the square bottom plate 31 by threaded connection, and the side of the L-shaped baffle 32 is connected to the short side of the glass, which is used for side limiting when the glass is translated.

[0023] Further, such as Figure 8-9 As shown, in this embodiment, the pushing mechanism 6 includes a pushing cylinder 41 arranged along the vertical direction. When the glass needs to be moved down from the first working position to the second working position, the push rod of the pushing cylinder 41 changes from an extended state to a contracted state; the side panels 42 are symmetrically arranged on both sides of the pushing cylinder 41, and the top of the side panels 42 are fixedly connected to the bottom of the base 1 by threads; the support plate 43 is fastened to the upper surface of the push plate of the pushing cylinder 41 by threaded connection, and four symmetrically arranged guide rods 44 are fixedly connected to the upper surface of the support plate 43 by threaded connection; the upper ends of the two guide rods 44 on the same side are fixedly connected with a bracket 45 by threaded connection, and the pushing mechanism 6 is used to support the glass to move down from the first working position to the second working position.

[0024] Further, such as Figure 10-13As shown, the translation mechanism 7 includes a linear slide 51, a linear motor 52 and a pushing assembly 53 for pushing the glass to move horizontally. In the present embodiment, the bottom surfaces of the linear slide 51 and the linear motor 52 are both fixedly connected to the top of the base 1 by threaded connection; the linear slide 51 and the linear motor 52 are arranged in parallel, and a connecting plate 55 is provided between the linear motor 52 and the linear slide 51, wherein the connecting plate 55 is rectangular, and the two ends of the rectangle are respectively threadedly connected to the two sliders above the linear slide 51, and the middle part of the connecting plate 55 is fixedly connected to the slide seat on the linear motor 52, and when the linear motor 52 reciprocates in the horizontal direction, it drives the pushing assembly 53 on the linear slide 51 to move in the horizontal direction.

[0025] Furthermore, the push assembly 53 includes: a first push plate 54, a lifting cylinder 56, a blocking plate 57, and a second push plate 58. In this embodiment, the bottom end of the first push plate 54 is fixed to the slider at the end of the linear slide 51 by threaded connection; the lifting cylinder 56 is fixedly connected to the top of the slider in the middle of the linear slide 51 through an L-shaped fixing plate; the blocking plate 57 is threadedly connected to the push block at the top of the lifting cylinder 56; the bottom of the second push plate 58 is also fixed to the push block at the top of the lifting cylinder 56, and the spacing between the first push plate 54 and the blocking plate 57 is fixed to accommodate the width of a glass, which is used to drive the glass to move in a horizontal square, and the spacing between the blocking plate 57 and the second push plate 58 is fixed, so that the interval between the glass at the second working position and the third working position is always fixed, and orderly unloading is achieved.
