Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of glass production equipment, especially relates to loading device and glass production line. BACKGROUND

[0002] In the process of batch production of glass sheet, glass sheet needs to be stacked up for batch transfer between different production processes, or stacked up for temporary storage. In the prior art, glass sheet is usually stacked on an L-shaped frame. However, when glass sheet is stacked on the L-shaped frame, the front side of the L-shaped frame is in an open state. Once the forklift truck avoids personnel or malfunctions due to emergency braking, the glass on the L-shaped frame will move to the front side due to inertia, which will eventually cause the glass to fall and break, and even cause safety accidents of personal injury. Especially during the transfer process, the vibration generated when passing through a bumpy ground is more likely to cause the glass sheet to fall.

[0003] In order to prevent the glass from falling, the glass and the L-shaped frame are usually bundled with adhesive tape. However, since the number of glass loaded on the L-shaped frame is not fixed, when the number of glass is small, the space occupied by the glass is small, which cannot ensure the firmness of the adhesive tape and the complete adhesion between the adhesive tape and the glass. Therefore, the glass may still fall during the transfer, causing the glass to break. SUMMARY

[0004] The purpose of the embodiments of the present application is to provide a loading device, which aims to solve the problem of how to improve the universality of the loading device.

[0026] Please refer to Figures 1 to 3 The embodiment of the application provides a loading device for loading a plate material 200, the loading device comprises a placing rack 10 and a limiting piece 30, the placing rack 10 has a first supporting surface 11 supporting the plate material 200 along a first direction a and a second supporting surface 12 supporting the plate material 200 along a second direction b, the first direction a and the second direction b are arranged at an angle, a placing area 400 of the plate material 200 is formed between the first supporting surface 11 and the second supporting surface 12, the limiting piece 30 is slidingly arranged in the placing area 400 and the limiting piece 30 is arranged at an interval from the second supporting surface 12, the plate material 200 is limited between the limiting piece 30 and the second supporting surface 12, and the limiting piece 30 can slide in the direction close to or away from the second supporting surface 12, so as to adjust the interval between the limiting piece 30 and the second supporting surface 12.

[0027] It can be understood that the plate material 200 can be a glass plate. Of course, in other possible embodiments, the plate material 200 can also be a wooden plate, a stainless steel plate, or a plastic plate, and the like plate-shaped material, and the specific structure of the plate material 200 is not uniquely limited in the embodiments of the present application.

[0028] In addition, a plurality of plate materials 200 can be placed on the rack 10, and the plurality of plate materials 200 are vertically arranged and closely attached to each other. The plate material 200 can be placed obliquely or vertically. In some embodiments, the first direction a is a vertical direction, the first support surface 11 supports the bottom of the plate material 200, and the second support surface 12 supports one side of the plate material 200, that is, the second support surface 12 can be used for the plate material 200 to abut, at this time, when the number of plate materials 200 is different, the space occupied by the plate material 200 as a whole is different. Of course, a plurality of plate materials 200 can also be stacked on the first support surface 11, at this time, for plate materials 200 of different sizes, the space occupied by the plate material 200 as a whole is different.

[0029] In the embodiments of the present application, the first support surface 11 is used to support the bottom of the plate material 200, and the second support surface 12 is used to support one side of the plate material 200, so that the state of the plate material 200 is stable, and the second support surface 12 can be vertically arranged or inclined at an angle relative to the vertical surface, as long as it can abut one side of the plate material 200. Optionally, the first direction a and the second direction b are perpendicular to each other.

[0030] The limiting piece 30 and the second support surface 12 of the embodiments of the present application jointly limit the plate material 200, when the forklift performs forklift operation from the rear side of the rack 10, if the plate material 200 moves forward due to emergency braking to avoid personnel or failure objects, under the limitation of the limiting piece 30, the plate material 200 will not fall, thereby avoiding safety accidents.

[0031] The position of the limiting piece 30 can be adjusted in the embodiments of the present application, so that the distance between the limiting piece 30 and the second support surface 12 can be flexibly adjusted according to the space occupied by the plate material 200, that is, the limiting area of the plate material 200 between the limiting piece 30 and the second support surface 12 is adjusted, thereby improving the versatility of the loading device, so that it can adapt to different plate material 200 loading conditions.

[0032] In some embodiments, the loading device further comprises a connecting rod 20, one end of the connecting rod 20 is connected to the second support surface 12, the other end of the connecting rod 20 extends away from the second support surface 12, and the limiting piece 30 is slidingly connected to the connecting rod 20, so that the limiting piece 30 can slide along the length direction of the connecting rod 20. By slidingly connecting the limiting piece 30 to the connecting rod 20, the limiting piece 30 can be driven to slide by external force, and the structure is simple, which can improve the adjustment efficiency. Optionally, the connecting rod 20 and the second support surface 12 are perpendicular to each other, that is, the connecting rod 20 extends along the second direction b.

[0033] In the embodiments of the present application, one end of the connecting rod 20 is connected to one side edge of the second support surface 12. Specifically, the one end of the connecting rod 20 can be connected to the top of the second support surface 12, or can be connected to the left and right sides of the second support surface 12. When the one end of the connecting rod 20 is connected to the top of the second support surface 12, the limiting piece 30 extends towards the first support surface 11. Specifically, when the one end of the connecting rod 20 is connected to the top of the second support surface 12, the limiting piece 30 extends along the first direction a.

[0034] In some embodiments, as shown in Figure 2 The limiting piece 30 includes a telescopic rod 31 and an abutting piece 32. One end of the telescopic rod 31 is in sliding connection with the connecting rod 20, and the other end of the telescopic rod 31 extends towards the placement area 400. The abutting piece 32 is connected to the end of the telescopic rod 31 away from the connecting rod 20. The length of the telescopic rod 31 is adjustable. By adjusting the length of the telescopic rod 31, the extension length of the limiting piece 30 can be adjusted, and thus the limiting range of the limiting piece 30 can be adjusted. The size of the sheet material 200 can be adjusted flexibly. For example, when the size of the sheet material 200 is large, the telescopic rod 31 can be lengthened, so that the abutting piece can be deep into the placement area 400 and can abut against the center of the sheet material 200, to ensure the limiting effect of the limiting piece 30. When the size of the sheet material 200 is small, the telescopic rod 31 can be retracted. In addition, when the sheet material 200 needs to be taken off from the loading device, the telescopic rod 31 can be retracted to avoid interference of the telescopic rod 31 with the sheet material 200, thereby improving the convenience and safety of unloading. Optionally, the extension direction of the telescopic rod 31 is parallel to the second support surface 12.

[0035] In use, the telescopic rod 31 is retracted first, and then the sheet material 200 is stacked in the placement area 400. After the sheet material 200 is placed, the telescopic rod 31 is lengthened, so that the abutting piece is deep into the placement area 400 and abuts against the center of the outermost sheet material 200, to avoid the sheet material 200 from falling. When the sheet material 200 needs to be taken off from the placement rack 10, the telescopic rod 31 is retracted, which is simple and convenient to operate.

[0036] In some embodiments, as shown in Figure 2 The telescopic rod 31 includes a first rod segment 311 and a second rod segment 312 in sliding connection with the first rod segment 311. The second rod segment 312 can move telescopically relative to the first rod segment 311 along the length direction of the first rod segment 311. The first rod segment 311 is connected with the connecting rod 20, and the second rod segment 312 is connected with the abutting piece 32. Through the telescopic movement of the first rod segment 311 and the second rod segment 312, the structure is simple, the adjustment mode is simple, and the adjustment efficiency is improved.

[0037] Specifically, the second rod segment 312 is sleeved on the first rod segment 311, and when the second rod segment 312 moves along the length direction of the first rod segment 311, the first rod segment 311 can limit the movement of the second rod segment 312, thereby ensuring the straightness of the movement of the first rod segment 311 and avoiding the deviation of the first rod segment 311.

[0038] In some embodiments, the first rod segment 311 and the second rod segment 312 can be circular steel pipes, which are easy to obtain and have simple structure, thereby reducing the cost and manufacturing difficulty. In this case, the cross sections of the first rod segment 311 and the second rod segment 312 are circular, which facilitates the relative rotation of the first rod segment 311 and the second rod segment 312, thereby facilitating the adjustment of the relative positions of the first rod segment 311 and the second rod segment 312. In other possible implementations, the first rod segment 311 and the second rod segment 312 can also be square tubes, which have strong structural strength and can improve the stability of the limiting piece 30, thereby ensuring the limiting effect.

[0039] In some embodiments, the telescopic rod 31 further comprises a limiting pin 313, the first rod segment 311 is provided with a plurality of first fixing holes 3111 arranged at intervals along the length direction of the first rod segment 311, the second rod segment 312 is provided with a plurality of second fixing holes 3121 arranged at intervals along the length direction of the second rod segment 312, and the limiting pin 313 is selectively arranged in one of the first fixing holes 3111 and one of the second fixing holes 3121, so as to limit the second rod segment 312 on the first rod segment 311. Thus, the first rod segment 311 and the second rod segment 312 can be locked after the telescopic rod 31 is adjusted to the preset length, thereby ensuring the stability of the telescopic rod 31 during use, avoiding loosening, falling off or skewing due to external force, and improving the stability of the limiting piece 30.

[0040] In some embodiments, the distance between two adjacent first fixing holes 3111 on the first rod segment 311 along the length direction of the first rod segment 311 is equal, and the distance between two adjacent second fixing holes 3121 on the second rod segment 312 along the length direction of the second rod segment 312 is equal, thereby ensuring the consistency of each length adjustment. Of course, in other possible implementations, the distances between two adjacent first fixing holes 3111 on the first rod segment 311 along the length direction of the first rod segment 311 are arranged in an arithmetic sequence or a geometric sequence in turn, and the distances between two adjacent second fixing holes 3121 on the second rod segment 312 along the length direction of the second rod segment 312 are arranged in an arithmetic sequence or a geometric sequence in turn, thereby enabling quick adjustment for different sizes of the sheet material 200 and improving the adaptability and flexibility of the limiting piece 30.

[0041] In some embodiments, the loading device further comprises a locking member 40 connected between the connecting rod 20 and the sleeve 33, the locking member 40 has a first state and a second state, when the locking member 40 is in the first state, the locking member 40 limits the sliding of the telescopic rod 31 along the length direction of the connecting rod 20; when the locking member 40 is in the second state, the locking member 40 removes the limitation on the sliding of the telescopic rod 31. By arranging the locking member 40, when the locking member 40 is in the first state, the telescopic rod 31 and the connecting rod 20 cannot slide relative to each other, so that the distance between the limiting member 30 and the second support surface 12 is stable, the size of the limiting area between the limiting member 30 and the second support surface 12 is stable, and the safety of placing the plate material 200 is improved.

[0042] In some embodiments, as shown in Figure 2 The telescopic rod 31 is connected with the sleeve 33 at an end away from the abutting member 32, and the sleeve 33 is slidably sleeved on the connecting rod 20. The sleeve 33 is slidably sleeved on the connecting rod 20, and the connecting rod 20 can limit the movement range of the sleeve 33, so that when the sleeve 33 slides, the connecting rod 20 can guide the sliding of the sleeve 33 to some extent, avoiding the movement of the sleeve 33 and the telescopic rod 31 from deviating.

[0043] Optionally, the connecting rod 20 and the sleeve 33 can be square tubes, which have high structural strength, can improve the stability of the connecting rod 20 and the sleeve 33, are easy to obtain, have simple structure, and can reduce cost and manufacturing difficulty.

[0044] Further, the sleeve 33 is provided with a through hole penetrating the inner cavity of the sleeve 33, and the locking member 40 is movably arranged in the through hole, when the locking member 40 is in the first state, the locking member 40 abuts against the connecting rod 20 to limit the sliding of the sleeve 33; when the locking member 40 is in the second state, the locking member 40 is separated from the connecting rod 20. It can be understood that when the locking member 40 is in the first state, the locking member 40 abuts against the connecting rod 20, thereby clamping the sleeve 33, and the sleeve 33 cannot slide relative to the connecting rod 20; when the locking member 40 is in the second state, the locking member 40 is separated from the connecting rod 20, and the sliding of the sleeve 33 is not blocked. Optionally, the locking member 40 is a limiting bolt, a fixed pin or an elastic protruding column, etc.

[0045] In some embodiments, the abutting member 32 is provided with a protective pad 34 for contacting the plate material 200, and the protective pad 34 is a flexible member. By arranging the protective pad 34 and the protective pad 34 being a flexible member, the abutting member 32 can avoid hard contact with the plate material 200 and realize flexible contact, thereby achieving a certain buffering effect and avoiding scratching the glass. Optionally, the material of the protective pad 34 can be foam, sponge, rubber or silicone, etc.

[0046] In some embodiments, as shown in Figure 3As shown, the placing rack 10 is provided with a connecting structure 50 for attaching the external component 300 to the placing rack 10, so that the loading device can carry the external component 300, which helps to expand the function of the loading device. For example, when the plate material 200 of the embodiment of the application is a glass plate, the door plate and cover plate of a wooden box for packaging the glass plate can be attached to the connecting structure 50, and the size of the wooden box corresponds to the size of the glass plate, so that the wooden box corresponding to the glass plate can be quickly found according to the door plate and cover plate during subsequent packaging of the glass plate.

[0047] Optionally, the connecting structure 50 is a hook, and the external component 300 can be hung on the hook. Of course, in other possible embodiments, the connecting structure 50 is an adhesive pad or a suction cup, etc., for attaching or adsorbing the external component 300, and the specific structure of the connecting structure 50 is not uniquely limited in the embodiment of the application, as long as the external component 300 can be attached to the placing rack 10.

[0048] In some embodiments, the second supporting surface 12 is also provided with a buffer pad 60 made of flexible material, which can avoid hard contact between the second supporting surface 12 and the plate material 200, and has a certain buffering effect to avoid scratching the plate material 200.

[0049] The utility model also proposes a glass production line, the glass production line includes loading device, the specific structure of loading device refers to the above-embodiment, because the glass production line adopts all technical schemes of the above-mentioned all embodiments, therefore also has all beneficial effects brought by the technical scheme of the above-mentioned embodiment, here will not repeat again.

[0050] In summary, the position of the limiting piece 30 can be adjusted according to the occupied space of the plate material 200, so that the distance between the limiting piece 30 and the second supporting surface 12 can be flexibly adjusted, that is, the limiting area of the plate material 200 between the limiting piece 30 and the second supporting surface 12 is adjusted, so as to improve the versatility of the loading device, so that it can adapt to different plate material 200 loading conditions.

[0051] The above is only an optional embodiment of the application and is not intended to limit the application. The application can have various changes and modifications for those skilled in the art.
