Description

Technical Field

[0001] The invention relates to a tube core material sorting mechanism. Background Art

[0002] Paper tube cores are mainly used for spandex winding, tape processing, etc. There are two specifications of paper tube cores, short and long. The height of the long version is twice that of the short version. The height of the long tube core is 115mm and the outer diameter is 84mm. The current material sorting mechanism pushes the paper tube onto the conveyor belt through the oblique pushing component. The height of the conveying channel is only for the vertical short paper tube core to pass through. The horizontal paper tube core is higher than the height of the conveying channel. Therefore, the horizontal paper tube core is eliminated, and the paper tube cores entering the conveying channel are all vertical paper tube cores. However, this material sorting mechanism is only suitable for short tube cores, not long tube cores. The current long tube cores are still sorted manually, which has the problems of low material sorting efficiency and high labor costs. Summary of the Invention

[0003] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide a tube core sorting machine for arranging long tube cores.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: This tube core material sorting mechanism is characterized by comprising a plurality of groups of pusher assemblies, which are divided into a top pusher assembly and a bottom pusher assembly, the pusher assemblies are arranged obliquely, and the pusher assemblies include

[0005] A fixing plate is mounted on the frame and arranged in a stepped manner;

[0006] and push plates, which are mounted on a lifting plate that moves obliquely up and down and are arranged in a stepped manner, with the push plates and fixed plates being alternately arranged;

[0007] When the lifting plate rises to the feeding station, the top of the push plate is not lower than the fixed plate on the same layer; when the lifting plate descends to the receiving station, the top of the push plate is not higher than the fixed plate on the lower layer;

[0008] A screening part is provided on the top of the push plate of the top pusher assembly, and the screening part includes a base and support ribs vertically arranged on the base, and the support ribs are evenly arranged laterally on the base. The fixed plate and the support ribs or the fixed plate and the upper end surface of the base and the support ribs can support the tube core in a horizontal horizontal state, but cannot support the tube core in a vertical state and the tube core in a longitudinal horizontal state.

[0009] The pushing assembly of the present invention pushes the tube cores upward layer by layer. The top-layer pushing assembly adopts a screening piece to make the tube cores in the vertical state and the tube cores in the longitudinal horizontal state placed on the screening piece lose balance and automatically fall down, leaving only the tube cores in the transverse horizontal state. In this way, the tube cores sent out by the top-layer pushing assembly are only the tube cores in the transverse horizontal state, and the state of the tube cores is unified, thereby realizing automatic material sorting and saving labor costs.

[0010] Preferably, the length from the fixing plate of the top pusher assembly to the longitudinal end of the support rib is close to, but not less than, the radius of the tube core; and the distance between the centerlines of adjacent support ribs is less than the height of the tube core. This allows for support of a tube core in a horizontal position. Furthermore, the closer the length from the fixing plate to the longitudinal end of the support rib is to the radius of the tube core, the more likely the tube core in other positions will fall. Conversely, the longer the length from the fixing plate to the longitudinal end of the support rib is, the less likely the tube core will fall.

[0011] Preferably, the spacing between adjacent support ribs is smaller than the outer diameter of the tube core, so that the tube core in the longitudinal horizontal state will not be stuck between the two support ribs, and the fixed plate and the support ribs are not sufficient to support the tube core in the vertical state and the longitudinal horizontal state. Therefore, the tube core in the vertical state or the longitudinal horizontal state will automatically fall off the screening piece due to loss of balance.

[0012] Preferably, the spacing between the center lines of adjacent supporting ribs is not less than the radius of the tube core. If a tube core is supported by only two supporting ribs, the balance of the vertical tube core will inevitably be broken, causing it to automatically fall from the screening element.

[0013] Preferably, the top of the fixed plate and / or the push plate of the lower pushing assembly is provided with a screening piece; adding the screening piece improves the success rate of screening out the tube cores in the horizontal longitudinal state and the vertical state; the support ribs of the screening pieces on adjacent fixed plates and push plates are staggered, and the support position of the tube core changes when it moves from the fixed plate to the push plate or from the push plate to the fixed plate, so the balance of the tube core will also change, and the tube cores in the horizontal longitudinal state and the vertical state will be more easily separated from the screening piece, and the success rate of screening out will be higher.

[0014] Preferably, the upper corners of the longitudinal ends of the support ribs are arc-shaped, which reduces the stress between the tube core and the support ribs, so that the tube core will not be scratched when it slides off the support ribs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following describes the details and working principles of the embodiments and examples of the present invention in conjunction with the accompanying drawings. The X axis is the horizontal direction, also the left-right direction, the Y axis is the longitudinal direction, also the front-back direction, and the Z axis is the vertical direction, also the up-down direction.

[0021] The material handling mechanism of this material handling machine includes several groups of pushing components, which are divided into a top pushing component 10 and a lower pushing component. The lower pushing component can be set as one group or multiple groups. Figure 2 Three groups are set up in it; the pushing assembly includes a fixed plate 4 and a pushing plate 5. The pushing assembly is tilted and tilted in the discharge direction. When pushing the tube core, the tube core is transported obliquely upward. The tube core not only moves upward, but also moves horizontally, so that the tube core can leave the hopper. Moreover, the pushing assembly is tilted so that the angle formed by the upper end faces of the fixed plate 4 and the pushing plate 5 and the vertical plane is less than 90 degrees, so that the tube core is automatically transferred from the pushing plate 5 to the fixed plate 4 or from the fixed plate to the pushing plate during the pushing process. The tilt angle of the pushing assembly is preferably close to 15 degrees. If the angle is too large, the tube core is not easy to screen. If it is too small, the moving range is too small and the tube core cannot be sent out. The fixed plate 4 is mounted on the frame and is arranged in a stepped manner; the push plate 5 is mounted on a lifting plate 12 that moves obliquely up and down and is also arranged in a stepped manner. The angle of oblique movement of the lifting plate 12 is consistent with the angle of inclination of the pusher assembly. The push plate 5 and the fixed plate 4 are alternately arranged, that is, the push plate is arranged between the two fixed plates, and the fixed plate is arranged between the two push plates, and the push plate is arranged on the outside of the fixed plate; the lifting plate moves between the feeding station and the receiving station. The lifting of the lifting plate 12 can be achieved by a cylinder, a screw mechanism, a cam structure, etc. The upper end surfaces of the push plate and the fixed plate have a The lifting plate 12 has a fixed width. When the lifting plate 12 descends to the material receiving station, the top of the push plate is not higher than the lower fixed plate. Since the upper end surfaces of the fixed plate and the push plate are inclined downward, the tube core on the fixed plate automatically enters the upper end surface of the lowered push plate. When the lifting plate rises to the feeding station, the top of the push plate is not lower than the fixed plate on the same layer. In this way, the tube core on the push plate automatically enters the upper end surface of the fixed plate on the same layer. When the push plate 5 pushes the tube core, the tube core rests on the fixed plate 4 and moves up along the fixed plate until the push plate moves up to the feeding station. The lifting plate 12 drives the push plate to move down to pick up materials and moves up to feed materials, so that the tube core moves up layer by layer.

[0022] The upper end surfaces of the push plate and the fixed plate are narrow. During the lifting process, the tube core 3 in the vertical state or the tube core 2 in the longitudinal horizontal state is easy to fall, while the tube core 1 in the transverse horizontal state is not easy to fall. Therefore, the closer to the top layer, the more tube cores 1 in the transverse horizontal state, and the fewer tube cores in other states. The top of the push plate of the top pusher assembly 10 is provided with a screening member 11, which includes a base 7 and support ribs 6 vertically arranged on the base. The support ribs are evenly arranged horizontally on the base. The fixed plate 4 and the support ribs 6 or the fixed plate 4 and the upper end surface 9 of the base and the support ribs 8 can support the tube core 1 in a horizontal position, but cannot support the tube core 3 in a vertical position and the tube core 2 in a vertical position. The screening member 11 breaks the balance of the tube core 3 in a vertical position and the tube core 2 in a vertical position, causing them to automatically fall from the screening member. Therefore, after being screened by the screening member, only the tube core 1 in a horizontal position remains on the screening member. Finally, the push plate 5 of the top pusher assembly 10 pushes out the tube cores in a uniform horizontal position, realizing automatic material sorting. The fixed plate of the top pusher assembly can be connected to the conveyor belt. The push plate 5 of the top pusher assembly moves upward, allowing the tube core to cross the fixed plate 4 and enter the conveyor belt, and the conveyor belt sends the tube core out.

[0023] The base 7 and the support rib 6 can be formed in one piece or can be connected in a separate piece. Figure 4 The upper end surface 9 of the base and the upper end surface 8 of the support rib are on the same horizontal plane. The upper end surface 9 of the base is a narrow side, and the support surface formed by the upper end surface of the base and the support rib is shown in FIG. Figure 5The base 7 and support rib 6 are integrally formed, and the support rib is provided on the upper end surface of the base. The upper end surface 8 of the support rib is the support surface. The factors that affect the balance of the tube core on the screening member 11 are: the length S from the fixed plate to the longitudinal end of the support rib, the spacing L between adjacent support members, the angle ɑ between the fixed plate and the upper end surface of the support rib, the inclination angle of the pusher assembly, the thickness of the tube core, the width D of the support rib, and the thickness of the upper end surface 9 of the base in Example 1. Many factors affect this. For ease of installation, processing, and debugging, the angle ɑ between the fixed plate and the upper end surface of the support rib is generally set to 90 degrees. Therefore, the length S from the fixed plate of the top pusher assembly to the longitudinal end of the support rib should not be less than the radius R of the tube core. Otherwise, the tube core 1 in a horizontally horizontal position will fall. If the angle ɑ between the fixed plate and the upper end surface of the support rib is greater than 90 degrees, the length from the fixed plate to the longitudinal end of the support rib is slightly less than the radius of the tube core, and the tube core in a horizontally horizontal position can also be supported. The following explanations are based on the example of a 90-degree angle ɑ between the fixed plate and the support rib. The radius R of the tube core refers to half of the outer diameter of the tube core. The closer the length S from the fixed plate 4 to the longitudinal end of the support rib 6 is to the radius of the tube core, the easier it is for the tube core in other states to lose balance on the screening piece 11 and the easier it is to fall off. Conversely, the longer the length S from the fixed plate to the longitudinal end of the support rib is, the less likely the tube core will fall off. Therefore, it is best for the length S from the fixed plate to the longitudinal end of the support rib to be close to the radius of the tube core. The distance M between the center lines of adjacent support ribs is smaller than the height H of the tube core, which can ensure that the fixed plate 4 and the support ribs 6 can support the tube core 1 in the horizontal state, but the spacing L between adjacent support ribs will affect the tube core in the longitudinal horizontal state and the vertical state. If the spacing L between adjacent support ribs is larger than the outer diameter of the tube core, the tube core in the longitudinal horizontal state may be stuck between the two support ribs 6, affecting the pushing of the tube core. In order to improve the screening rate, the spacing L between adjacent support ribs is smaller than the outer diameter of the tube core, which not only avoids the above situation, but is also sufficient to support the tube core 1 in the horizontal state. The length S from the fixed plate to the longitudinal end of the support rib cannot support the tube core in the vertical state and the longitudinal horizontal state. Therefore, the tube core in the vertical state or the longitudinal horizontal state will automatically fall off the screening piece 11 due to loss of balance. Because the thickness of the tube core and the width D of the support rib will also affect the balance of the tube core, the wider the support rib 6, the more difficult it is to break the balance of the tube core on the screening piece. Conversely, the narrower the support rib, the easier it is to break the balance of the tube core on the screening piece, and the easier it is to fall from the screening piece 11. However, if the support rib 6 is too thin and the strength is insufficient, the tube core with thickness is heavy, and the support rib will be deformed and broken. Moreover, if the support rib 6 is too thin, its upper surface becomes sharp and it is easy to scratch the tube core. Therefore, the support rib must have a certain thickness, which is both strong and will not cause damage to the tube core. Moreover, the upper corner B of the longitudinal end of the support rib is arc-shaped, which can reduce the stress between the tube core and the support rib 6, and the tube core will not be scratched when it slides off the support rib.If the supporting ribs are wide enough and the spacing L between adjacent supporting ribs is too narrow, a tube core in a vertical state is supported by more than two supporting ribs, then the tube core may maintain balance and will not fall off the screening piece. If the spacing M between the center lines of adjacent supporting ribs is not less than the radius R of the tube core, then a tube core 3 in a vertical state is supported by only two supporting ribs 6, and the length S from the fixed plate to the longitudinal end of the supporting rib is close to the radius of the tube core, then the balance of the vertical tube core will inevitably be broken, causing it to automatically fall off the screening piece.

[0024] Because the tube core moves up layer by layer, it is screened and rejected in the process of moving up. In order to improve the screening rate, in addition to setting the screening piece 11 on the push plate of the top pusher assembly 10, the screening piece 11 can also be set on the fixed plate 4 or / and the push plate 5 of the lower pusher assembly. Adding the screening piece will improve the success rate of screening the tube core in the horizontal longitudinal state and the vertical state. It can be selected according to needs. Figure 2 In the present invention, the screening elements are only provided on the push plate of the top push assembly and the push plate and fixed plate of the second push assembly. The support ribs 6 of the screening elements on the adjacent fixed plates and push plates are staggered, see the attached figure. Figure 3 The support ribs of the screening piece on the fixed plate of the second-layer pusher assembly are between the adjacent support ribs of the screening piece on the push plate of the top-layer pusher assembly. Similarly, between the adjacent support ribs of the screening piece on the push plate of the second-layer pusher assembly, the tube core moves from the fixed plate to the push plate or from the push plate to the fixed plate. The contact surface between different support ribs and the tube core will change, and the balance of the tube core will also change. Then the tube core in the horizontal longitudinal state and the vertical state will be easier to detach from the screening piece, and the success rate of screening will be higher.
