[0037] Example 1

[0038] This embodiment provides a material transfer tool, such as Figure 1-Figure 12 As shown, the material transfer tooling includes a frame 1, a supporting component 2, a driving component 3 and a conveying component 4. The supporting component 2 is arranged in the frame 1, the driving component 3 is connected to one end of the conveying component 4, and the other end of the conveying component 4 returns to the driving component 3 after passing through the frame 1 and the supporting component 2; the driving component 3 can drive the supporting component 2 to move up and down in the frame 1 through the conveying component 4.

[0039] Specifically, the frame 1 has a certain height, and its general outline is a rectangular parallelepiped structure, and there is a space inside, in which the supporting assembly 2 is arranged. The driving assembly 3 is arranged on one side of the frame 1, and is used to provide driving force for the movement of the supporting assembly 2. One end of the transmission assembly 4 is connected to the driving assembly 3, and the other end is also fixed to the driving assembly 3 after being reciprocatedly wound around the top of the frame 1 and the bottom of the supporting assembly 2, and is used to transfer the force of the driving assembly 3 to the supporting assembly 2. After adopting the above structure, the material to be transported is placed on the supporting assembly 2, and the driving assembly 3 works, which can drive the transmission assembly 4 to move. Since the transmission assembly 4 bypasses the bottom of the supporting assembly 2 when it is set, the transmission assembly 4 can drive the supporting assembly 2 to move up and down in the frame 1, thereby driving the material to rise.

[0040] This embodiment uses material transfer tooling to replace traditional manual handling, thereby reducing the labor intensity of the staff and avoiding safety hazards that exist during the handling process.

[0041] In a specific embodiment, Figure 4 , Figure 5 as well as Figure 6 As shown, the material transfer tooling also includes a blocking component 5 arranged in the frame 1, and the blocking component 5 is arranged at one end of the supporting component 2 and connected to the supporting component 2; when the blocking component 5 follows the supporting component 2 to rise to a certain height, the blocking component 5 is blocked by the frame 1, so that when the supporting component 2 rises to the target height, the top of the blocking component 5 is not higher than the supporting component 2.

[0042] The blocking component 5 is mainly used to prevent the material from falling during the rising process. For a clearer explanation below, it is assumed that in a certain embodiment, the supporting component 2 has four sides. After the height of the supporting component 2 reaches the required level, the side of the supporting component 2 from which the material is lifted is called one end of the supporting component 2, the other side opposite to the end is called the other end, and the remaining two sides are called the two sides of the supporting component 2. In this embodiment, the blocking component 5 is arranged at one end of the supporting component 2 and is connected to the supporting component 2.

[0043] During the process of the support assembly 2 rising, since the blocking assembly 5 is connected to the support assembly 2, the blocking assembly 5 will also rise synchronously to prevent the material from falling through one end of the support assembly 2 during the rising process. As the support assembly 2 rises, when it is about to rise to the target position, a blocking member is provided on the frame 1, which can make the blocking assembly 5 stay at this position and not continue to rise. In the process of the blocking assembly 5 not moving and the support assembly 2 continuing to rise, since the part of the blocking assembly 5 that is higher than the support assembly 2 still exists, but the height of this part is gradually decreasing, that is, in this process, the height difference between the blocking assembly 5 and the support assembly 2 is shrinking. Since there is a height difference, the blocking assembly 5 still has a blocking effect, and the material will not fall at this time. As the support assembly 2 continues to rise, when it is flush with the top of the blocking assembly 5 or slightly lower than the top of the blocking assembly 5, the support assembly 2 has risen to the target height. At this time, the blocking assembly 5 set at one end of the support assembly 2 does not have a blocking function, and the material can be transferred to the next process at this end.

[0044] In a specific embodiment, Figure 2 As shown, the supporting component 2 includes a supporting bracket 21 and a smooth strip 22, wherein the smooth strip 22 is arranged on the supporting bracket 21, and both sides of the supporting bracket 21 are higher than the smooth strip 22 to prevent the material on the smooth strip 22 from falling from both sides; the height of the smooth strip 22 gradually increases from one end to the other end; the blocking component 5 is arranged on the side of the smooth strip 22 where the height is lower.

[0045] The supporting bracket 21 includes multiple transverse lean tubes and vertical lean tubes. More specifically, the supporting bracket 21 has two layers, the bottom layer includes at least two transverse lean tubes, and the top layer includes at least two transverse lean tubes, and the lean tubes on the top layer gradually rise from one end of the supporting component 2 to the other end; the vertical lean tubes are arranged on both sides, on the one hand, they are used to connect the bottom layer and the top layer to provide support points for the transverse lean tubes on the bottom layer and the top layer, and on the other hand, the vertical lean tubes are higher than the smooth strips 22 on the lean tubes on the top layer to prevent the material on the smooth strips 22 from falling from both sides.

[0046] Among them, the smooth strip 22 in this embodiment is the abbreviation of the aluminum alloy slide rail. The supporting bracket 21 is composed of a lean tube. The lean tube (also called a wire rod) is a steel-plastic composite tube with an outer plastic layer, a middle metal layer and an inner rust-proof layer. The current process is that the plastic layer is directly attached to the metal layer. The wire rod product is a modular system composed of pipe fittings and wire rod connectors, which can convert any creative idea into a personalized and practical structure, and is extremely simple, quick and low-cost to manufacture. In addition, in this embodiment, due to the inclined setting of the smooth strip 22, the material can slide directly from one side of the handover to the next process without the need for additional power.

[0047] In a specific embodiment, Figure 5 As shown, the blocking assembly 5 includes a fixed rod arranged in the frame 1, a limiting rod 52 located below the fixed rod and a blocking rod 53 vertically connected to the limiting rod 52; a spring 54 is sleeved on the blocking rod 53, and above the spring 54, the blocking rod 53 has a step 51; below the spring 54, one end of the supporting bracket 21 extends a sleeve 23, and the sleeve 23 is sleeved on the blocking rod 53; when the limiting rod 52 and the blocking rod 53 rise to a certain height following the supporting bracket 21, the limiting rod 52 is blocked by the fixed rod, and the supporting assembly 2 continues to rise until the top of the blocking rod 53 is no higher than the lower side of the smooth strip 22.

[0048] More specifically, the blocking component 5 provided in this embodiment mainly has the following three states:

[0049] The first one is: the spring 54 is located between the step 51 of the blocking rod 53 and the sleeve 23 of the supporting bracket 21, and is basically not compressed. The entire blocking assembly 5 moves upward together with the supporting bracket 21. At this time, the blocking rod 53 is higher than the smooth strip 22, and can block the material.

[0050] The second type is: as the blocking assembly 5 of the supporting bracket 21 rises, the limiting rod 52 is stuck by the fixing rod, and the limiting rod 52 cannot move further, so the blocking rod 53 connected to the limiting rod 52 cannot move either; but at this time, since the supporting bracket 21 continues to move upward, the sleeve 23 connected to the supporting bracket 21 also continues to move. During the movement of the sleeve 23, the spring 54 is squeezed, and the distance difference between the smooth strip 22 and the top of the blocking rod 53 is shrinking.

[0051] The third type is: when the supporting bracket 21 rises to the target position, the spring 54 is also squeezed to the limit position by the sleeve 23. At this time, the distance difference between the smooth strip 22 and the top of the blocking rod 53 is zero, and the smooth strip 22 is even higher than the top of the blocking rod 53. At this time, the blocking rod 53 loses its blocking effect, and the material can slide from this end to the next process.

[0052] In a specific embodiment, Figure 2 and Fig. 9 As shown, the driving assembly 3 includes a rocking arm 31, a ratchet 32 ​​and a pawl, wherein the ratchet 32 ​​is mounted on the rocking arm 31, and the pawl is located on the frame 1. The pawl has a first state in which it cooperates with the ratchet 32 ​​to prevent the rocking arm 31 from rotating, and a second state in which it does not contact the ratchet 32 ​​so that the rocking arm 31 can rotate.

[0053] The rotating member with the ratchet 32 ​​is the rocker 31. When the rocker 31 rotates in the positive direction, the supporting assembly 2 can drive the material to rise. Conversely, when the rocker 31 rotates in the reverse direction, the supporting assembly 2 can be lowered. In one embodiment, the driving assembly 3 also includes a switch. When the switch is turned off, the ratchet can play a role to prevent the return. When the switch is turned on, the rocker can be rotated in the reverse direction to lower the supporting device.

[0054] More specifically, the pawl is designed to extend from the connection to both sides, one side interacts with the ratchet 32, and the other side is exposed outside the structure so that the operator can turn it, that is, switch. When closed, the pawl and the ratchet 32 ​​are in contact with each other, which can play a non-return effect; when opened, the pawl and the ratchet 32 ​​are not in contact, and the ratchet 32 ​​can rotate clockwise or counterclockwise as the rocker 31.

[0055] In a specific embodiment, Figure 7 As shown, the transmission component 4 includes a first pull rope 41, a first fixed pulley 42 and a second fixed pulley 43, the first fixed pulley 42 has a plurality and all are arranged on the top of the frame 1, the second fixed pulley 43 has a plurality and all are arranged on the bottom of the supporting component 2, one end of the first pull rope 41 is fixed on the rocker 31, and the other end of the first pull rope 41 is reciprocated up and down and passes through the first fixed pulley 42 and the second fixed pulley 43 and then is fixed on the rocker 31.

[0056] In this embodiment, the frame 1, the rocker 31 and the supporting assembly 2 are linked together by the first pull rope 41, so that the operating rocker 31 can drive the supporting assembly 2 to move up and down. In addition, the first fixed pulley 42 and the second fixed pulley 43 in this embodiment are used to change the direction.

[0057] In a specific embodiment, the transmission component 4 also includes a second pull rope 44, a counterweight block 45 and a movable pulley 46, the counterweight block 45 is connected to the movable pulley 46, one end of the second pull rope 44 is fixed to one side of the top of the frame 1, and the other end of the second pull rope 44 passes downward through the second fixed pulley 43 at the bottom of the supporting component 2, then passes upward through the movable pulley 46 and is fixed to the other side of the top of the frame 1.

[0058] The second pull rope 44, the counterweight 45 and the movable pulley 46 enable the supporting assembly 2 to automatically descend, and the movable pulley 46 and the counterweight 45 utilize gravity to achieve a labor-saving effect.

[0059] In a specific embodiment, the material transfer tool further includes a universal wheel 6, which is disposed at the bottom of the frame 1. By installing the universal wheel 6, the material transfer tool can be moved in all directions. The universal wheel 6 is a so-called movable caster, and its structure allows horizontal 360-degree rotation. The universal wheel 6 can make the material transfer tool provided in this embodiment move conveniently, so that it can be used in different equipment and docked with different processes.

[0060] In another embodiment, the material transfer tooling is also designed with a foot brake to improve the stability of the supporting assembly during lifting.

[0061] In a specific embodiment, the frame 1 includes a plurality of lean tubes, and the plurality of lean tubes are interconnected to form the frame 1 .

[0062] The material transfer tooling provided in the present embodiment can control the lifting and lowering of the supporting component 2 by using the first fixed pulley 42, the second fixed pulley 43 and the rocker 31; the movable pulley 46 is used to achieve the effect of saving effort when the supporting component 2 is lifted and lowered; and by designing the ratchet pawl, the rocker can be locked to prevent the supporting component from falling due to gravity after it is lifted up, and at the same time, a switch is added to the ratchet to control the state of the ratchet, which can be locked when closed and can be lowered by shaking the rocker in the opposite direction when opened; in addition, the material transfer tooling provided in the present embodiment is also provided with a blocking component 5, which can control the material to prevent it from falling during the rising process and will not affect its automatic sliding to the next process.
