Description

Technical Field

[0002] During the processing, controlling the loading and unloading of workpieces manually in cooperation with a crane is not only time-consuming and laborious, but also only one workpiece can be transported each time. However, during large-scale processing, multiple workpieces are usually processed at a time, which results in a large amount of time being consumed for loading and unloading operations before each processing.

[0003] For this reason, Chinese Patent No. CN203544984U with the authorization announcement number discloses a variable-rail mobile platform vehicle, which can perform loading and unloading through the centralized transportation of the trolley. Through the self-movement and variable rail of the variable-rail mobile platform vehicle, the interference problem between the opening of the high-pressure autoclave sealing end cover and the glass transportation workshop for entering the autoclave is effectively solved, and the structural gap problem between the track in the high-pressure autoclave cabin and the sealing end cover is effectively solved by its articulated track.

[0004] However, when using the trolley for loading and unloading, the workpiece on the trolley still needs to be transferred into the processing device, and the existing sandblasting processing line usually performs loading and unloading operations at the feeding end of the sandblasting machine. Before each loading, the unloading operation needs to be carried out first, resulting in frequent material accumulation at the feeding end of the sandblasting machine, causing the sandblasting machine to stop and wait.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention realizes the function of simultaneously loading and unloading multiple workpieces at the feeding end and the discharging end of the sandblasting machine through a translation conveyor, a double-trolley translation machine and a lifting control mechanism. It can load materials while unloading materials, achieve the effect of synchronous transfer and synchronous processing of multiple workpieces, improve the operation time of the sandblasting machine, reduce the operation consumption of the sandblasting machine, and solve the problem that traditional equipment still needs manual assistance in material transfer after completing material transportation.

Detailed implementation mode

[0031] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation modes.

[0032] Refer to Figures 1 - 3 : A workpiece translation and transportation device for a sandblasting processing line, which is used to transport workpieces to a sandblasting machine. The translation and transportation device includes a feeding conveyor device arranged at the feeding end of the sandblasting machine and a discharging conveyor device arranged at the discharging end of the sandblasting machine. Both the feeding conveyor device and the discharging conveyor device include a translation conveyor 1, a double trolley translation machine 2 and a material transfer table 3 for carrying workpieces; there are three groups of translation conveyors 1, which are used to move the material transfer table 3 into or out of the sandblasting machine; the double trolley translation machine 2 is used to control the material transfer table 3 to move into or out of the translation conveyor 1. The double trolley translation machine 2 includes two material transfer trolleys 21 and a linear drive assembly 24 for controlling the movement of the material transfer trolleys 21. Each material transfer trolley 21 is provided with a lifting platform 22 that can move in the vertical direction. There is a gap for the material transfer trolleys 21 to move between two adjacent groups of translation conveyors 1; each material transfer trolley 21 is provided with a lifting control mechanism 4 for driving the lifting of the lifting platform 22.

[0033] The present invention realizes the functions of simultaneously loading and unloading multiple workpieces at the feeding end and the discharging end of the sandblasting machine through the translation conveyor 1, the double trolley translation machine 2 and the lifting control mechanism 4. It can load while unloading, achieving the effects of synchronous transfer and synchronous processing of multiple workpieces, improving the operating time of the sandblasting machine and reducing the operating consumption of the sandblasting machine. It solves the problem that traditional equipment still requires manual assistance for material transfer after completing material transportation. A slide rail for guiding the movement of the material transfer vehicle 21 is provided on the ground of the working area, and the slide rail extends to the gap between adjacent translation conveyors 1. The linear drive assembly 24 includes a first rotary drive 241 and a screw 242. The first rotary drive 241 is preferably a servo motor with self-locking ability. The first rotary drive 241 is used to drive the screw 242 to rotate, and the screw 242 is threadedly connected to the material transfer vehicle 21. In the working state, the operator first erects the transfer table 3 on the lifting platform 22 of the double trolley translation machine 2 with the assistance of a crane or other tools. Then, workpieces of different volumes are moved onto the transfer table 3, and the lifting platform 22 is lifted by controlling the lifting control mechanism 4. Then, the screw 242 is rotated by driving the rotary drive, and the screw 242 drives the material transfer vehicle 21 connected to it by thread to move along the slide rail. The material transfer vehicle 21 drives the lifting platform 22 to move, and the transfer table 3 is moved onto the translation conveyor 1 through the two lifting platforms 22. Then, the lifting platform 22 is lowered by controlling the lifting control mechanism 4 to erect the transfer table 3 on the translation conveyor 1. Then, the transfer table 3 is moved into the sandblasting machine through the translation conveyor 1 for sandblasting processing. After processing, the transfer table 3 is moved onto the lifting platform 22 of the material transfer vehicle 21 through the translation conveyor 1 at the discharging end, and the transfer table 3 is moved out of the translation conveyor 1 by the two material transfer vehicles 21.

[0034] Refer to Figures 1 - 4 : The lifting control mechanism 4 includes a linear drive 41 and a support assembly 42. Both the linear drive 41 and the support assembly 42 are provided on the material transfer vehicle 21. The linear drive 41 is used to push the lifting platform 22 upward. When the lifting platform 22 is in the rising state, the support assembly 42 provides support for the lifting platform 22.

[0035] The present invention realizes the function of controlling the lifting of the lifting platform 22 through the linear driver 41 and the support assembly 42, and can provide sufficient supporting force for the material transfer table 3 by controlling the support assembly 42. The linear driver 41 is preferably a linear cylinder or an electric push rod. Before transferring the material transfer table 3 to the horizontal conveyor 1, the operator first pushes the lifting platform 22 upward through the linear driver 41. When the lifting platform 22 is in the rising state, the support assembly 42 holds up the lifting platform 22 to provide continuous supporting force. At this time, the linear driver 41 resets and no longer pushes the lifting platform 22. The linear drive assembly 24 controls the movement of the material transfer cart 21. After moving the material transfer table 3 into the horizontal conveyor 1, the support of the support assembly 42 for the lifting platform 22 is cancelled, and the lifting platform 22 moves under the action of gravity, and then places the material transfer table 3 on the horizontal conveyor 1.

[0036] Refer to Figure 4 and Figure 5 : The support assembly 42 includes a support table 421, a sliding seat 422, a support rod 423 and a guide rod 424; the support table 421 is movably arranged on the material transfer cart 21, and the support table 421 is connected to the lifting platform 22; a first guide rail 211 is provided on the material transfer cart 21, and the sliding seat 422 is slidably installed on the first guide rail 211; the number of the support rods 423 and the sliding seats 422 is at least two. The two support rods 423 are respectively located on both sides of the support table 421, and both ends of the support rod 423 are hinged to the sliding seat 422 and the support table 421 respectively; the guide rod 424 is arranged at the bottom of the support table 421, the guide rod 424 extends in the vertical direction, and the guide rod 424 is slidably matched with the material transfer cart 21; an auxiliary control mechanism 5 for restricting the movement of the sliding seat 422 is further provided on the material transfer cart 21.

[0037] The present invention realizes the function of providing supporting force for the lifting platform 22 when the lifting platform 22 is in the upward movement state through the support table 421, the sliding seat 422, the support rod 423, the guide rod 424 and the auxiliary control mechanism 5. And through the inclined support design of the support rod 423, the load can be effectively transmitted and dispersed, the overall stability of the structure can be enhanced, and the load distribution can be optimized. When the pressure distribution of the workpiece on the material transfer table 3 is uneven, the shear force and bending moment borne by the guide rod 424 can be reduced. When the lifting platform 22 moves upward under the pushing action of the linear driver 41, the lifting platform 22 drives the support table 421 to move, and when the support table 421 moves, it will pull the support rod 423, and the support rod 423 transmits the pulling force to pull the sliding seat 422 to move along the first guide rail 211. When the lifting platform 22 is in the rising state, the movement of the sliding seat 422 is restricted by the auxiliary control mechanism 5, and then the inclined support is carried out by using the support rod 423. And two support rods 423 and two sliding seats 422 are provided on both sides of the support table 421, further improving the comprehensiveness of the support and avoiding structural damage caused by pressure concentration.

[0038] Refer toFigures 4 - 7 : The auxiliary control mechanism 5 includes a transmission component 51 and a fixing component 52; there are two groups of the transmission components 51, and the two groups of transmission components 51 are respectively arranged on both sides of the support table 421. The transmission component 51 includes a slider 511, a first rotating shaft 512, a transmission disc 513, a connecting rod 514 and a rotating gear 515; a second guide rail 212 is provided on the material transfer cart 21, the slider 511 is slidably installed on the second guide rail 212, a push rod 213 is movably arranged on the material transfer cart 21, the push rod 213 is connected to the sliding seat 422, and the slider 511 and the push rod 213 are connected by a rod member. A first fixed shaft 5111 is provided on the slider 511; the first rotating shaft 512 is rotatably arranged on the material transfer cart 21, the transmission disc 513 is sleeved on the first rotating shaft 512, a second fixed shaft 5131 is provided on the transmission disc 513, and the axis of the second fixed shaft 5131 deviates from the axis of the transmission disc 513; the two ends of the connecting rod 514 are respectively hinged to the first fixed shaft 5111 and the second fixed shaft 5131; the rotating gear 515 is sleeved on the first rotating shaft 512, and the rotating gears 515 of the two groups of transmission components 51 are meshed and connected; the fixing component 52 is arranged on the material transfer cart 21, and the fixing component 52 is used to limit the rotation of one of the transmission discs 513.

[0039] Through the transmission component 51 and the fixing component 52 of the present invention, the function of restricting the movement of the sliding seat 422 is realized. At the same time, through the setting of the transmission component 51, when one of the sliding seats 422 moves, it can control the other sliding seat 422 to move in the opposite direction, thereby reducing the shear force on the guide rod 424. The push rod 213 is connected to the two sliding seats 422 on the same side. When the material transfer table 3 is locally over-pressed due to different sizes and masses of the workpieces, through the support of the two side support rods 423, the deformation of the guide rod 424 can be avoided, and the situation that the material transfer table 3 is skewed can be avoided. When the sliding seat 422 moves, it drives the push rod 213 to move, and then the pulling force transmitted through the rod member can drive the slider 511 to move synchronously. The slider 511 pulls the transmission disc 513 to rotate around its axis through the connecting rod 514. The transmission disc 513 drives the first rotating shaft 512 and the rotating gear 515 to rotate, and then drives the other transmission disc 513 to rotate in the opposite direction through the meshing of the two rotating gears 515. The other transmission disc 513 pulls the sliding seat 422 and the slider 511 on the same side through the connecting rod 514 to move, so as to keep the two sliding seats 422 move in the opposite direction or in the reverse direction when moving, and keep the force on both sides of the support table 421 balanced.

[0040] Refer to Figures 7 - 9: The fixing assembly 52 includes a mounting seat 521, a limit block 522 and a connecting disk 523; the mounting seat 521 is arranged on the material moving platform 3, and a base 5211 connected to the material moving platform 3 is provided at the bottom of the mounting seat 521; the limit block 522 is slidably installed on the mounting seat 521, and a first elastic member 5221 is provided on the limit block 522, and the two ends of the first elastic member 5221 are respectively connected to the limit block 522 and the mounting seat 521; the connecting disk 523 is coaxially connected to the first rotating shaft 512, and a third fixed shaft 5231 is eccentrically arranged on the connecting disk 523; when the third fixed shaft 5231 is between the limit block 522 and the base 5211, the rotation of the connecting disk 523 is restricted.

[0041] The present invention realizes the function of limiting the rotation of the transmission disk 513 through the mounting seat 521, the limit block 522 and the connecting disk 523. Since the two transmission disks 513 are connected by two rotating gears 515, when the rotation of one of the transmission disks 513 is limited, the movement of the slides 422 on both sides of the support platform 421 can be limited. As the lifting platform 22 moves upward, the transmission disk 513 also rotates under the tensile force transmitted by each part, thereby driving the first rotating shaft 512 and the connecting disk 523 to rotate. The limit block 522 has an arc surface on one side away from the base 5211. When the third fixed shaft 5231 on the connecting disk 523 contacts the limit block 522, the arc surface of the limit block 522 is squeezed, and the first elastic member 5221 contracts under the pressure, and the limit block 522 moves accordingly, and the third fixed shaft 5231 passes through the limit block 522 smoothly. At this time, the lifting platform 22 is in an ascending state, and the third fixed axis 5231 on the connecting plate 523 is located between the limit block 522 and the base 5211. The limit block 522 and the base 5211 are both in contact with the third fixed axis 5231, respectively limiting the movement of the third fixed axis 5231 in two directions.

[0042] Reference Figure 1 , Figure 2 and Figure 10 The translation conveyor 1 comprises a bracket 11, a second rotating shaft 12, a material transfer roller 13 and a rotation drive assembly 14; a bearing seat 111 is provided on the bracket 11, and the second rotating shaft 12 is rotatably arranged on the bearing seat 111; the material transfer roller 13 is sleeved on the second rotating shaft 12; the rotation drive assembly 14 is arranged on the bracket 11, and the rotation drive assembly 14 is used to drive the second rotating shaft 12 to rotate.

[0043] The present invention realizes the function of driving the transfer table 3 to translate through the support 11, the bearing seat 111, the second rotating shaft 12, the transfer roller 13 and the rotation driving assembly 14, achieving the effect of moving the transfer table 3 out of or into the sandblasting machine. The number of the second rotating shaft 12 and the transfer roller 13 is at least two. After the transfer table 3 is moved above the transfer roller 13 by the double trolley translation machine 2, the lifting control mechanism 4 is used to control the lowering of the lifting platform 22. After the transfer table 3 contacts the transfer roller 13, the transfer roller 13 supports the transfer table 3. Then, the rotation driving assembly 14 is used to drive the plurality of second rotating shafts 12 to rotate. The second rotating shaft 12 drives the transfer roller 13 to rotate, and the transfer table 3 is pushed into the sandblasting machine for sandblasting processing.

[0044] Refer to Figure 2 and Figure 10 : The rotation driving assembly 14 includes a second rotation driver 141; the second rotation driver 141 is used to drive the second rotating shaft 12 to rotate; a sprocket 142 is sleeved on each second rotating shaft 12, a chain 143 is sleeved on the sprocket 142, and the sprockets 142 on the adjacent second rotating shafts 12 are connected by the chain 143.

[0045] The present invention realizes the function of driving the plurality of second rotating shafts 12 to rotate synchronously through the second rotation driver 141, the sprocket 142 and the chain 143. The second rotation driver 141 is preferably a servo motor. The driving end of the second rotation driver 141 is coaxially connected to one of the second rotating shafts 12. In the working state, when the transfer table 3 is on the transfer roller 13, the operator drives the second rotating shaft 12 connected to its driving end to rotate through the second rotation driver 141. Then, the second rotating shaft 12 controls the adjacent second rotating shaft 12 to rotate synchronously through the sprocket 142 and the chain 143. Furthermore, the plurality of second rotating shafts 12 and the transfer roller 13 are controlled to rotate synchronously through the second rotation driver 141, and then the transfer table 3 located thereon is pushed to translate.

[0046] Refer to Figure 7 and Figure 8 : The transfer table 3 is provided with a control assembly 53 for releasing the rotation restriction of the transmission disc 513 by the fixing assembly 52. The control assembly 53 includes a push plate 531, a vertical plate 532 and a second elastic member 533; the push plate 531 is slidably arranged on the mounting seat 521, the vertical plate 532 is connected to the mounting seat 521, and the two ends of the second elastic member 533 are respectively connected to the push plate 531 and the vertical plate 532; when the push plate 531 is subjected to a thrust force, the second elastic member 533 contracts, and the push plate 531 pushes the limiting block 522 to move away from the third fixed shaft 5231.

[0047] The present invention realizes the function of controlling the movement of the limit block 522 through the push plate 531, the vertical plate 532 and the second elastic member 533, achieving the effect of releasing the rotation restriction of the fixing assembly 52 on the transmission disc 513. When the material transfer table 3 is moved directly above the material transfer roller 13, an operator applies a thrust to the push plate 531. The push plate 531 transmits the thrust to the second elastic member 533. The second elastic member 533 is compressed and contracts. At this time, the push plate 531 moves and pushes the limit block 522 to move away from the third fixed shaft 5231, causing the limit block 522 to separate from the third fixed shaft 5231. After the movement restriction of the limit block 522 on the third fixed shaft 5231 is released, the movement of the sliding seat 422 is no longer restricted, and the lifting platform 22 moves downward under the action of gravity.

[0048] Refer to Figure 4 and Figure 5 : One end of the material transfer cart 21 close to the horizontal conveyor 1 is provided with a buffer assembly 25. The buffer assembly 25 includes a baffle 251 and a third elastic member 252; both ends of the third elastic member 252 are respectively connected to the material transfer cart 21 and the baffle 251.

[0049] The present invention realizes the function of buffering when the material transfer cart 21 contacts other objects through the baffle 251 and the third elastic member 252. The end of the ground slide rail is provided with a limit pile for restricting the movement of the material transfer cart 21. When the baffle 251 at the end of the material transfer cart 21 contacts the limit pile, the movement is restricted, and the baffle 251 is subjected to an extrusion effect. The third elastic member 252 contracts under the pressure transmitted by the baffle 251, and the impact generated by the collision is buffered by the elastic force generated by the deformation of the third elastic member 252. After the material transfer cart 21 moves into place, the first rotary driver 241 stops driving, and the material transfer cart 21 is fixed by the self-locking of the first rotary driver 241. At this time, the third elastic member 252 is in a contracted state.

[0050] Refer to Figure 4 and Figure 5 : An extension rod 253 is connected to the baffle 251. The extension rod 253 is slidably matched with the material transfer cart 21; in the working state, during the process of the baffle 251 moving towards the material transfer cart 21, the extension rod 253 on the baffle 251 contacts the push plate 531 and then pushes the push plate 531.

[0051] The present invention realizes the function of pushing the push plate 531 when the material transfer vehicle 21 moves to the position of the limit pile by setting the extension rod 253. When the material transfer vehicle 21 moves to the position of the limit pile, the baffle plate 251 moves under the squeezing action of the limit pile, thereby pushing the extension rod 253 to move. After the extension rod 253 contacts the push plate 531, it pushes the push plate 531. The second elastic member 533 contracts under the thrust, thereby pushing the limit block 522 to move through the push plate 531, so that the limit block 522 is separated from the third fixed shaft 5231, and the rotation restriction of the fixed component 52 on the transmission plate 513 is released.

[0052] Workflow: In the working state, the operator first sets up the material transfer platform 3 on the lifting platform 22 of the double-trolley translation machine 2 with the assistance of a crane or other tools, then moves multiple workpieces of different volumes onto the material transfer platform 3, and controls the lifting platform 22 to rise through the lifting control mechanism 4. When the lifting platform 22 moves upward under the push of the linear drive 41, the lifting platform 22 drives the support platform 421 to move, and the support platform 421 pulls the support rod 423 when moving, and the support rod 423 transmits the pulling force to pull the slide 422 to move along the first guide rail 211. As the lifting platform 22 moves upward, the transmission disk 513 also rotates under the pulling force transmitted by each part, thereby driving the first rotating shaft 512 and the connecting disk 523 to rotate. When the third fixed shaft 5231 on the connecting plate 523 contacts the limit block 522 and squeezes the arc surface of the limit block 522, the first elastic member 5221 contracts under the pressure, the limit block 522 moves accordingly, and the third fixed shaft 5231 passes through the limit block 522 smoothly. At this time, the lifting platform 22 is in an ascending state, the third fixed shaft 5231 on the connecting plate 523 is located between the limit block 522 and the base 5211, the limit block 522 and the base 5211 are in contact with the third fixed shaft 5231, and the movement of the third fixed shaft 5231 in two directions is restricted respectively, thereby restricting the movement of the slide 422, and then the support rod 423 is used for oblique support. Then the screw 242 is driven to rotate by the rotary driver, and the screw 242 drives the material transfer vehicle 21 threadedly connected thereto to move along the slide rail, and the material transfer vehicle 21 drives the lifting platform 22 to move, and the material transfer platform 3 is moved to the translation conveyor 1 through the two lifting platforms 22. Then, the lifting platform 22 is controlled to move downward by the lifting control mechanism 4, and the material transfer platform 3 is set up on the translation conveyor 1, and then the material transfer platform 3 is moved into the sandblasting machine for sandblasting through the translation conveyor 1. After the processing is completed, the material transfer platform 3 is moved to the lifting platform 22 of the material transfer vehicle 21 through the translation conveyor 1 at the material discharge end, and the material transfer platform 3 is moved out of the translation conveyor 1 through the two material transfer vehicles 21.

[0053] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
