However, when performing large-scale processing, multiple workpieces are usually processed at a time, which results in a lot of time spent on loading and unloading operations before each processing.

[0003] To this end, a Chinese patent with authorization announcement number CN203544984U discloses a track-changing mobile platform vehicle, which can load and unload materials through centralized transportation of trolleys.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 3 : A workpiece translation transport device for a sandblasting processing line is used to transport workpieces to a sandblasting machine. The translation transport device includes a feed conveying device arranged at the feed end of the sandblasting machine and a discharge conveying device arranged at the discharge end of the sandblasting machine. The feed conveying device and the discharge conveying device both include a translation conveyor 1, a double-trolley translation machine 2 and a material transfer platform 3 for carrying workpieces; the translation conveyor 1 is provided with three groups for moving the material transfer platform 3 into or out of the sandblasting machine; the double-trolley translation machine 2 is used to control the material transfer platform 3 to move into or out of the translation conveyor 1, the double-trolley translation machine 2 includes two material transfer carts 21 and a linear drive assembly 24 for controlling the movement of the material transfer cart 21, each material transfer cart 21 is provided with a lifting platform 22 that can move in a vertical direction, and there is a gap between two adjacent groups of translation conveyors 1 for the material transfer cart 21 to move; each material transfer cart 21 is provided with a lifting control mechanism 4 for driving the lifting platform 22 to rise and fall.

[0033] The present invention realizes the function of 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, and can load materials while unloading materials, so as to 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 the traditional equipment still needs manual assistance in material transfer after completing the material transportation. A slide rail for guiding the movement of the material transfer vehicle 21 is arranged 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 driver 241 and a screw 242. The first rotary driver 241 is preferably a servo motor with self-locking capability. The first rotary driver 241 is used to drive the screw 242 to rotate. The screw 242 is threadedly connected to the material transfer vehicle 21. 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, and then moves a plurality of workpieces of different volumes to the material transfer platform 3, and controls the lifting platform 22 to rise through the lifting control mechanism 4. 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 control mechanism 4 controls the lifting platform 22 to move downward, sets up the material transfer platform 3 on the translation conveyor 1, and then moves the material transfer platform 3 into the sandblasting machine through the translation conveyor 1 for sandblasting. 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 discharging end, and the material transfer platform 3 is moved out of the translation conveyor 1 through the two material transfer vehicles 21.

[0034] Reference Figure 1-Figure 4 : The lifting control mechanism 4 includes a linear drive 41 and a support assembly 42; the linear drive 41 and the support assembly 42 are both arranged on the material transfer vehicle 21, and the linear drive 41 is used to push the lifting platform 22 to move upward; when the lifting platform 22 is in an ascending state, the support assembly 42 provides support for the lifting platform 22.

[0035] The present invention realizes the function of controlling the lifting and lowering of the lifting platform 22 through the linear drive 41 and the support assembly 42, and by controlling the support assembly 42, it can provide sufficient support force for the material transfer platform 3. The linear drive 41 is preferably a linear cylinder or an electric push rod. Before transferring the material transfer platform 3 to the translation conveyor 1, the operator first pushes the lifting platform 22 upward through the linear drive 41. When the lifting platform 22 is in the rising state, the support assembly 42 props up the lifting platform 22 and provides continuous support force. At this time, the linear drive 41 is reset and no longer pushes the lifting platform 22. The linear drive assembly 24 controls the movement of the material transfer vehicle 21. After the material transfer platform 3 is moved into the translation conveyor 1, the support of the support assembly 42 to the lifting platform 22 is cancelled, and the lifting platform 22 moves down under the action of gravity, and then the material transfer platform 3 is placed on the translation conveyor 1.

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

[0037] The present invention realizes the function of providing support force to the lifting platform 22 when the lifting platform 22 is in the upward state through the support platform 421, the slide 422, the support rod 423, the guide rod 424 and the auxiliary control mechanism 5, and the diagonal bracing design of the support rod 423 can effectively transfer and disperse the load, enhance the overall stability of the structure, and optimize the load distribution. When the pressure distribution of the workpiece on the material transfer platform 3 is uneven, the shear force and bending moment of the guide rod 424 are reduced. When the lifting platform 22 moves upward under the driving action of the linear drive 41, the lifting platform 22 drives the support platform 421 to move, and the support platform 421 will pull 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. When the lifting platform 22 is in the ascending state, the movement of the slide 422 is limited by the auxiliary control mechanism 5, and then the support rod 423 is used for oblique support. In addition, two support rods 423 and two slide seats 422 are provided on both sides of the support platform 421, so as to further improve the comprehensiveness of the support and avoid structural damage caused by pressure concentration.

[0038] Reference Figure 4-Figure 7 The auxiliary control mechanism 5 includes a transmission assembly 51 and a fixed assembly 52; the transmission assembly 51 is provided with two groups, and the two groups of transmission assemblies 51 are respectively arranged on both sides of the support platform 421, and the transmission assembly 51 includes a slider 511, a first rotating shaft 512, a transmission plate 513, a connecting rod 514 and a rotating gear 515; a second guide rail 212 is provided on the material transfer vehicle 21, and the slider 511 is slidably installed on the second guide rail 212, and a push rod 213 is movably provided on the material transfer vehicle 21, and the push rod 213 is connected to the slide seat 422, and the slider 511 is connected to the push rod 213 through a rod, and a first fixed assembly 514 is provided on the slider 511. Fixed shaft 5111; the first rotating shaft 512 is rotatably set on the material transfer vehicle 21, the transmission disk 513 is sleeved on the first rotating shaft 512, and a second fixed shaft 5131 is provided on the transmission disk 513, and the axis of the second fixed shaft 5131 deviates from the axis of the transmission disk 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 fixed component 52 is set on the material transfer vehicle 21, and the fixed component 52 is used to limit the rotation of one of the transmission disks 513.

[0039] The present invention realizes the function of limiting the movement of the slide 422 through the transmission component 51 and the fixing component 52. At the same time, through the setting of the transmission component 51, when one of the slides 422 moves, the slide 422 on the other side can be controlled to move toward each other, thereby reducing the shear force on the guide rod 424. The push rod 213 is connected to the two slides 422 on the same side. When the material transfer platform 3 is locally over-pressed due to the different sizes and masses of the workpieces, the support of the support rods 423 on both sides can prevent the guide rod 424 from deforming and causing the material transfer platform 3 to be skewed. When the slide 422 moves, it drives the push rod 213 The sliding block 511 is moved synchronously by the pulling force transmitted by the rod, and the sliding block 511 is driven to move synchronously by the sliding block 511, and the sliding block 511 pulls the transmission plate 513 to rotate around its axis through the connecting rod 514, and the transmission plate 513 drives the first rotating shaft 512 and the rotating gear 515 to rotate, and then the engagement of the two rotating gears 515 drives the transmission plate 513 on the other side to rotate in the opposite direction, and the transmission plate 513 on the other side pulls the sliding seat 422 and the sliding block 511 on the same side through the connecting rod 514, thereby keeping the sliding seats 422 on both sides moving towards or in the opposite direction when moving, and keeping the force on both sides of the support platform 421 balanced.

[0040] Reference Figure 7-Figure 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.

[0043] The present invention realizes the function of driving the material transfer platform 3 to translate through the bracket 11, the bearing seat 111, the second rotating shaft 12, the material transfer roller 13 and the rotating drive assembly 14, so as to achieve the effect of moving the material transfer platform 3 out of or into the sandblasting machine. The number of the second rotating shaft 12 and the material transfer roller 13 is at least two. After the material transfer platform 3 is moved to the top of the material transfer roller 13 by the double-trolley translation machine 2, the lifting control mechanism 4 is used to control the lifting platform 22 to move downward. After the material transfer platform 3 contacts the material transfer roller 13, the material transfer platform 3 is supported by the material transfer roller 13. Then, the rotating drive assembly 14 is used to drive the multiple second rotating shafts 12 to rotate, and the second rotating shafts 12 drive the material transfer roller 13 to rotate, so that the material transfer platform 3 is pushed into the sandblasting machine for sandblasting.

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

[0045] The present invention realizes the function of driving multiple second rotating shafts 12 to rotate synchronously through the second rotary driver 141, the sprocket 142 and the chain 143. The second rotary driver 141 is preferably a servo motor. The driving end of the second rotary driver 141 is coaxially connected to one of the second rotating shafts 12. In the working state, when the material transfer platform 3 is on the material transfer roller 13, the operator drives the second rotating shaft 12 connected to its driving end to rotate through the second rotary driver 141, and then the second rotating shaft 12 controls the second rotating shaft 12 adjacent to it to rotate synchronously through the sprocket 142 and the chain 143, and then controls the multiple second rotating shafts 12 and the material transfer roller 13 to rotate synchronously through the second rotary driver 141, and then promotes the translation of the material transfer platform 3 located thereon.

[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, so as to achieve the effect of releasing the rotation restriction of the fixed component 52 on the transmission disk 513. When the material transfer platform 3 is moved to the top of the material transfer roller 13, the operator applies a thrust to the push plate 531, and the push plate 531 transmits the thrust to the second elastic member 533, and the second elastic member 533 contracts under pressure. At this time, the push plate 531 moves and pushes the limit block 522 to move in a direction away from the third fixed shaft 5231, so that the limit block 522 is separated from the third fixed shaft 5231. After the limit block 522 releases the movement restriction on the third fixed shaft 5231, the movement of the slide 422 is no longer restricted, and the lifting platform 22 moves downward under the action of gravity.

[0048] Reference Figure 4 and Figure 5 A buffer assembly 25 is provided at one end of the material transfer vehicle 21 close to the translation conveyor 1.

Both ends of the third elastic member 252 are connected to the material transfer vehicle 21 and the baffle 251, respectively.

[0049] The present invention realizes the function of buffering when the material transfer vehicle 21 contacts other objects through the baffle plate 251 and the third elastic member 252. The end of the slide rail on the ground is provided with a limit pile for limiting the movement of the material transfer vehicle 21. When the baffle plate 251 at the end of the material transfer vehicle 21 contacts the limit pile, the movement is limited, and the baffle plate 251 is squeezed, the third elastic member 252 contracts under the pressure transmitted by the baffle plate 251, and the elastic force generated by the deformation of the third elastic member 252 is used to buffer the impact caused by the collision. After the material transfer vehicle 21 moves into place, the first rotary driver 241 stops driving, and the material transfer vehicle 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] Reference Figure 4 and Figure 5 : The baffle 251 is connected to an extension rod 253, and the extension rod 253 slides with the material transfer vehicle 21; in the working state, when the baffle 251 moves toward the direction close to the material transfer vehicle 21, the extension rod 253 on the baffle 251 contacts the push plate 531 and 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 only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
