Description

Technical Field

[0001] The invention relates to the technical field of loading and unloading of blister trays, in particular to a loading and unloading device for blister trays. Background Art

[0002] The parts produced in the workshop are generally evenly placed in blister trays for transportation. Blister trays are packaging products made of plastic sheets with grooves of specific shapes using the blister process. When in use, the products are placed in the grooves.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0025] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0026] Reference Figure 1 This embodiment provides a blister tray loading and unloading device, including a transmission assembly 1, which includes a first driving member 11, a transmission wheel 12 arranged outside the first driving member 11, a transmission belt 121 arranged outside the transmission wheel 12, and a transmission plate 13 arranged outside the transmission belt 121; and The clamping assembly 2 includes a movable plate 21 disposed above the transmission plate 13; and The lifting assembly 3 includes a second driving member 31 disposed between the transmission belts 121 , a driving rod 32 disposed above the second driving member 31 , and a shaft plate disposed outside the driving rod 32 .

[0027] The transmission assembly 1 also includes a tray 14 arranged between the movable plates 21. A transmission member 141 is provided on the inner side of the tray 14. When the tray 14 filled with the transmission member 141 needs to be transported, the first driving member 11 is driven, and the first driving member 11 drives the transmission wheel 12 to rotate. The transmission wheel 12 drives the outer transmission belt 121 to move. The transmission belt 121 drives the outer transmission plate 13 and the tray 14 on the transmission plate 13 to be transported.

[0028] The clamping assembly 2 also includes a first clamping plate 22 arranged above the movable plate 21. A clamping groove 221 is provided on the inner side of the first clamping plate 22, and a second clamping plate 23 is provided on the inner side of the movable plate 21. When the lifting assembly 3 raises the pallet 14 fully loaded with transmission parts 141 to the height of the area to be transported, the upper movable plate 21 is driven by the transmission plate 13 to move to the pallet 14, and the pallet 14 is clamped by the clamping groove 221 below the first clamping plate 22, and the second clamping plate 23 lifts the pallet 14, thereby achieving the clamping of the pallet 14 for stable transportation.

[0029] The lifting assembly 3 also includes a connecting plate 33 provided at one end of the shaft plate, a lifting plate 34 being provided at one end of the connecting plate 33, a carrying plate 35 being provided above the lifting plate 34, and a limit plate 351 being provided at the four ends of the carrying plate 35. When the pallet 14 fully loaded with the transmission member 141 needs to be lifted, the second driving member 31 is driven, and the shaft plate outside the driving rod 32 is driven to rise through the driving rod 32 above the second driving member 31, and then the connecting plate 33 at one end is driven to rise through the shaft plate, and the connecting plate 33 will drive the lifting plate 34 at one end and the carrying plate 35 above the lifting plate 34 to rise, and the carrying plate 35 will drive the pallet 14 placed on the upper end to rise, and the transmission plate 13 is transported by the subsequent transmission assembly 1 and the clamping assembly 2. When the empty pallet 14 needs to be lowered, the second driving member 31 is driven in the reverse direction, thereby driving the empty pallet 14 to be lowered and stacked.

[0030] The buffer assembly 4 includes a fixing plate 42 disposed at one end of the connecting plate 33 and a buffer rod 441 disposed below the fixing plate 42 .

[0031] Usage process: Two sets of lifting assemblies 3 are installed on the left and right sides of the inner side of the transmission assembly 1, and the lifting assemblies 3 on the left and right sides have the same structure and are used to stack pallets 14 and lift them. First, multiple pallets 14 loaded with transmission parts 141 are placed on the left lifting assembly 3. A full pallet 14 rises and is clamped by the clamping assembly 2. After the transmission parts 141 in the pallet 14 are grabbed by the robot arm, it is moved to the rightmost lifting assembly 3 for stacking. On the contrary, multiple empty pallets 14 can be placed through the left lifting assembly 3. When an empty pallet 14 rises and is clamped by the clamping assembly 2, the robot can grab all the transmission parts 141 and put them into the empty pallet 14 to make it full. Then it can be moved to the rightmost side and stacked at the rightmost lifting assembly 3. The device can be designed with the same structure so that the left and right sets of trays 14 can perform the same work, thereby improving work efficiency.

[0032] Example 2, reference Figures 1 to 7 , which is the second embodiment of the present invention. Different from the previous embodiment, it also includes a buffer assembly 4 and an operating plate 41 arranged between the lifting plates 34. A buffer plate 43 is provided above the operating plate 41, and an extrusion rod 44 is provided above the buffer plate 43. The extrusion rod 44 is sleeved on the outside of the buffer rod 441. When the lifting assembly 3 rises to the top quickly and collides with the baffle, the buffer assembly drives the second elastic member 461 to compress through the extrusion rod 44 and the first elastic member 451 to relay the buffering, thereby creating a secondary buffering effect, converting the inertial impact force into elastic potential energy, effectively offsetting the upward inertia of the tray 14, avoiding the scattering of the transmission parts 141 in the tray 14 due to bumps and take-off, and protecting the products in order.

[0033] A first sliding plate 45 is sleeved on the upper outer side of the buffer rod 441, a first elastic member 451 is provided above the first sliding plate 45, a second sliding plate 46 is sleeved on the lower outer side of the buffer rod 441, a second elastic member 461 is provided below the second sliding plate 46, and a limit plate 47 is provided below the buffer rod 441.

[0034] Usage process: The top of the lifting assembly 3 is installed with a baffle to limit its height and prevent it from falling off. At this time, when the lifting assembly 3 rises at a faster speed, the shaft plate will collide with the baffle with greater hardness, causing the tray 14 to take off due to inertia during the rising process, which will then cause the transmission parts 141 in the tray 14 to scatter. At this time, when the shaft plate rises to the top and collides with it, the lifting plate 34 will slide upward in the connecting plate 33 due to inertia. When the connecting plate 33 slides upward, the connecting plate 33 will drive the operating plate 41 to slide, and the sliding operating plate 41 will drive the buffer plate 43 to rise, and the buffer plate 43 will bring The dynamic extrusion rod 44 rises and squeezes the second elastic member 461. The squeezed second elastic member 461 will drive the second sliding plate 46 to rise through elastic potential energy. After the second sliding plate 46 rises a certain distance, the second sliding plate 46 will contact the first sliding plate 45, and the first sliding plate 45 will squeeze the first elastic member 451. The squeezed second elastic member 461 and the first elastic member 451 will be compressed and accumulate elastic potential energy, which will then offset the inertia of the lifting plate 34 when it rises, and without reducing the speed, it slows down the inertial force acting on the tray 14, thereby ensuring the overall working efficiency.

[0035] Example 3, reference Figures 1 to 7 , which is the third embodiment of the present invention. Different from the previous embodiment, it further includes a bearing assembly 5, which includes a first bearing groove 51 opened on the inner side of the lifting plate 34, an extrusion groove 52 opened above the first bearing groove 51, a second bearing groove 53 opened above the extrusion groove 52, and a sliding groove 54 opened at one end of the first bearing groove 51. A first extrusion block 55 is provided at the end of the connecting plate 33, a sliding inclined plate 56 is provided inside the sliding groove 54, an operating rod 57 is provided inside the first bearing groove 51, a receiving groove 571 is provided on the inner side of the operating rod 57, a second extrusion block 572 is provided on the inner side of the receiving groove 571, a reset rod 58 is provided above the operating rod 57, a third elastic member 581 is sleeved on the outer side of the reset rod 58, and a limiting rod 59 is provided above the reset rod 58. The outer diameter of the extrusion groove 52 is smaller than the second bearing groove 53, and the outer diameter of the third elastic member 581 fits the second bearing groove 53. When the limiting rod 59 moves downward, the limiting rod 59 will squeeze the third elastic member 581. The outer diameter of 52 is smaller than that of the third elastic member 581, so that the third elastic member 581 cannot move downward and is compressed. The compressed third elastic member 581 will accumulate elastic potential energy, so that after the supporting plate 35 is reset, under the action of the elastic potential energy of the third elastic member 581, the third elastic member 581 will drive the limit rod 59 to rise and re-engage in the supporting plate 35. When the limit rod 59 rises, the limit rod 59 will drive the reset rod 58 and the operating rod 57 below to reset and rise. After the operating rod 57 rises, the operating rod 57 squeezes the sliding inclined plate 56 through the second squeezing block 572, so that the sliding inclined plate 56 is reset, and the sliding inclined plate 56 squeezes the first squeezing block 55 to reset it.

[0036] It also includes a moving component 6, which includes a first moving groove 61 opened on the inner side of the lifting plate 34 and a second moving groove 62 opened at one end of the first moving groove 61, a first sliding column 63 is provided on the inner side of the second moving groove 62, a first connecting column 631 is provided at one end of the first sliding column 63, a second sliding column 64 is provided on the inner side of the first moving groove 61, a first fixed column 641 is provided at one end of the second sliding column 64, and a shaft 65 is provided between the first connecting column 631 and the first fixed column 641.

[0037] A second connecting column 632 is provided at one end of the first sliding column 63, a mounting plate 6321 is provided above the second connecting column 632, and the mounting plate 6321 is connected to the supporting plate 35. A second fixed column 642 is provided at one end of the second sliding column 64, a mounting block 66 is provided above the operating plate 41, a mounting plate 661 is provided on the inner side of the mounting block 66, and a transmission plate 662 is provided between the mounting plate 661 and the second fixed column 642.

[0038] When the lifting plate 34 is lifted by the force of inertia, the first extrusion block 55 at the top of the connecting plate 33 pushes the sliding inclined plate 56 toward the second extrusion block 572 through its inclined surface and squeezes the second extrusion block 572. When the second extrusion block 572 is squeezed, the second extrusion block 572 moves down through the contact and extrusion between the second extrusion block 572 and the inclined surface of the sliding inclined plate 56. The second extrusion block 572 drives the operating rod 57 to move down. When the operating rod 57 moves down, the operating rod 57 drives the upper reset rod 58 and the limit rod 59 to move down. After the limit rod 59 moves down, the limit rod 59 is separated from the carrier plate 35. At this time, the limit of the carrier plate 35 is released. When the carrier plate 35 is released from the limit, the rising operating plate 41 will rise by driving the mounting block 66. The mounting block 66 drives the second fixing column 642 to rise through the mounting plate 661. The second fixing column 642 The second sliding post 64 is driven to rise, and the rising second sliding post 64 will squeeze the first connecting post 631 through the shaft 65, and drive the first connecting post 631 to slide to the left. The sliding first connecting post 631 will drive the first sliding post 63 to slide to the left. After the first sliding post 63 slides to the left, the first sliding post 63 drives the released supporting plate 35 to slide to the left through the second connecting post 632 and the mounting plate 6321. At this time, the sliding supporting plate 35 will drive the fully loaded pallet 14 to slide, so that when the pallet 14 is lifted by inertia, the pallet 14 will also move to the left at the same time. In the process of the pallet 14 moving to the left, the transmission member 141 will also be close to the inner wall of the right side of the pallet 14 due to the inertia of the left side. After the transmission member 141 is close to the inner wall of the pallet 14, the friction force generated between the pallet 14 and the transmission member 141 prevents the transmission member 141 from being scattered due to inertia.

[0039] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
