Description

Technical Field

[0001] The invention relates to the field of parts conveying, in particular to a parts conveying device used in the production of engineering machinery. Background Art

[0002] Conveyor belts are composite products of rubber, fiber, metal, or plastic and fabric used in conveyor belts to carry and transport materials. Conveyor belts are widely used in cement, coking, metallurgy, chemical, steel and other industries where the conveying distance is short and the conveying volume is small.

[0003] After existing medium-sized mechanical parts are processed by machine tools, they need to be transferred to the next processing line through a conveyor belt. Usually, the overall mass is hundreds of pounds and the parts are hollow, so a crane and a sling are needed to place the parts on the conveyor belt, pass the sling through the hollow part of the part, and then pass one end of the sling through the other end of the sling, so that the sling can lock the inner and outer walls of the part, lock the two sides of the part through two slings, and then use the two slings to connect the crane, and place the parts on the conveyor belt through the crane. Since the parts are heavy, the slings that lock the parts will be locked, as shown in the knot. The more they are pulled, the tighter they are, so it is a waste of time to remove the slings, and since the edges of the initially processed parts are relatively sharp, when the crane pulls the parts on the sling to move, the parts will cut the slings, which will cause the crane to move the parts and the parts to fall off from the air, posing a safety hazard.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] See also Figure 1-Figure 3 A parts conveying device for engineering machinery production includes a transmission frame 1 and a plurality of electric rollers 2 installed on the upper end surface of the transmission frame 1. An adjustment device 3 is also installed on the upper end of the transmission frame 1. The adjustment device 3 is used to lift and rotate the parts. A stripping device 4 is also installed on the upper end of the transmission frame 1. The stripping device 4 includes a square frame 42 arranged on the upper end of the transmission frame 1. A convex thorn 46 is installed at one end of the square frame 42. The convex thorn 46 is used to tear the sling on the part;

[0044] Marking devices 5 are also installed at the upper and lower ends of the transmission frame 1. The two marking devices 5 are symmetrically arranged. The upper marking device 5 includes a through sleeve 53 arranged at the upper end of the transmission frame 1. A storage bin 54 is installed at the lower end of the through sleeve 53. A plurality of anti-cut sheets 55 are arranged inside the storage bin 54. A push plate 56 is also installed inside the storage bin 54. One end of the push plate 56 is connected to the inner wall of the storage bin 54 through a fourth spring 57. A push column 50 is slidably connected to the inside of the through sleeve 53. The push column 50 passes through the through sleeve 53 and the storage bin 54.

[0045] After existing medium-sized mechanical parts are processed by machine tools, they need to be transferred to the next processing line through a conveyor belt. Usually, the overall mass is hundreds of pounds and the parts are hollow, so a crane and a sling are required to cooperate to place the parts on the conveyor belt, pass the sling through the hollow part of the part, and then pass one end of the sling through the other end of the sling, so that the sling can lock the inner and outer walls of the part, and lock the two sides of the part through two slings, and then use the two slings to connect with the crane, and place the parts on the conveyor belt through the crane. Because the parts are heavy, the slings of the locked parts will be locked, and the more you pull, the tighter it will be, so it is a waste of time to remove the slings. In addition, because the edges of the initially processed parts are sharp, when the crane pulls the parts on the sling to move, the parts will cut the slings, which will cause the crane to move the parts, and the parts will fall off from the air, which poses a safety hazard.

[0046] according to Figure 1 As shown, the operator places the parts on the motorized roller 2 by means of a crane, and uses the motorized roller 2 to transfer the parts to the stripping device 4. Figure 2 As shown, the thorn 46 is used to abut against the part, and the part is lifted up and driven to rotate by the adjusting device 3, so that the thorn 46 will abut against the sling, and the sling is pulled by the thorn 46, so that the sling falls off the part, and then refer to Figure 3 When the sling falls off the part, the adjusting device 3 descends, and the part is transferred to the marking device 5 by the electric roller 2. The part is covered by the anti-cutting sheets 55 of the upper and lower marking devices 5. In this way, during the next process, the sling will contact the anti-cutting sheet 55, so that the sling avoids the edge of the part, thereby improving safety;

[0047] Specifically, according to Figure 3 As shown, when the part moves to the lower end of the storage bin 54, the push column 50 slides downward, and the push column 50 is used to press the anti-cut sheet 55 downward, and the anti-cut sheet 55 is in an inverted L shape, so that the anti-cut sheet 55 fits the edge of the part. Then, when the push column 50 is reset, the fourth spring 57 pushes the push plate 56 to squeeze the remaining anti-cut sheet 55 close to the lower end of the push column 50, so as to facilitate the subsequent anti-cut sheet 55 to fit on the part;

[0048] The anti-cutting sheet 55 includes a magnet and a protective sheet. A magnet is installed at one end of the protective sheet so that the anti-cutting sheet 55 can be firmly attached to the part.

[0049] Subsequently, after the anti-cutting sheet 55 is attached to the part, the part is continuously transferred by the motorized roller 2, thereby moving the part to the next processing location.

[0050] Embodiment 2:

[0051] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 6 The adjusting device 3 includes a rotating disk 32 rotatably connected to the upper end surface of the transmission frame 1, and the upper end surface of the rotating disk 32 is flush with the upper end of the electric roller 2;

[0052] A telescopic square sleeve is installed at the lower end of the rotating disk 32, and a motor 31 is installed at the lower end of the telescopic square sleeve. The lower end of the motor 31 is connected to one side of the transmission frame 1;

[0053] Two support columns 33 are disposed at the lower end of the rotating disk 32 . The support columns 33 penetrate the rotating disk 32 . A first trapezoidal plate 34 is also mounted on the outer surface of the motor 31 . The support columns 33 are used to abut against the first trapezoidal plate 34 .

[0054] See also Figure 6 , the telescopic square sleeve includes a square sleeve column and a sliding column;

[0055] See also Figure 2 When the part moves to the upper end surface of the rotating disk 32, the motor 31 drives the square sleeve column and the sliding column to rotate, the square sleeve column drives the rotating disk 32 to rotate, and the rotating disk 32 drives the supporting column 33 to rotate. The supporting column 33 will abut against the first trapezoidal plate 34, and the first trapezoidal plate 34 is trapezoidal, so that the first trapezoidal plate 34 is gradually squeezed to slide the supporting column 33 upward, so that the supporting column 33 drives the rotating disk 32 to slide upward, and the rotating disk 32 moves the part upward, so that the part can first move to the top of the rotating disk 32, and then the rotating disk 32 drives the part to rotate.

[0056] Embodiment 3:

[0057] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 6 The lower end of the rotating disk 32 is rotatably connected with a ring, the lower end of the ring is installed with a connecting frame 35, one end of the connecting frame 35 is slidably connected with a slide plate 36, the upper end of the slide plate 36 is installed with a cylinder 37, the inner wall of the cylinder 37 is installed with a protrusion 39, the inside of the cylinder 37 is slidably connected with a force rod 44, and the outer surface of the force rod 44 is provided with a plurality of rubber rings 38;

[0058] A connecting plate 43 is slidably connected inside the square frame 42 . The lower end of the connecting plate 43 is connected to the upper end of the force-bearing rod 44 . The upper end of the connecting plate 43 is connected to the inner wall of the square frame 42 via a first spring 45 .

[0059] according to Figure 2 and Figure 4 As shown, when the rotating disk 32 slides upward, the rotating disk 32 will also drive the connecting frame 35 to slide upward, and the connecting frame 35 drives the cylinder 37 to slide upward, and the cylinder 37 drives the protrusion 39 to slide upward, and the protrusion 39 contacts the rubber ring 38, thereby squeezing the first rubber ring 38 to slide upward through the protrusion 39, and the first rubber ring 38 drives the force rod 44 to slide upward, and the force rod 44 drives the connecting plate 43, the first spring 45 and the thorn 46 to slide upward, so that the thorn 46 can move the sling upward, and then when the protrusion 39 continues to slide upward, the protrusion 39 squeezes the first rubber ring 38 to deform, so that the protrusion 39 passes over the first rubber ring 38, so that the connecting frame 35 releases elastic potential energy, so that the first spring 45 pushes the connecting plate 43, the thorn 46 and the force rod 44 to reset, so that the sling is moved downward by the thorn 46, and so on and so forth, so that the node connecting the two ends of the sling is loosened;

[0060] It should be noted that, since the first spring 45 is always inserted in the auxiliary belt, when the motor 31 drives the rotating disk 32 to rotate multiple times, the rotating disk 32 also drives the sling on the part and the thorns 46 to tear each other, so that the sling falls off the part, thus realizing automatic stripping of the sling, thereby improving the processing efficiency of the operator;

[0061] A second telescopic column 41 is also installed at the upper end of the transmission frame 1, one end of the second telescopic column 41 is connected to one end of the square frame 42, and a fourth tube 47 is installed on one side of the second telescopic column 41;

[0062] A storage groove 48 is also provided on one side of the transmission frame 1, and the storage groove 48 is used to store the sling.

[0063] Since each part has a different size, a second telescopic column 41 is provided to push the square frame 42 to slide, so that the thorns 46 can contact parts of different sizes.

[0064] Embodiment 4:

[0065] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-Figure 6 A first telescopic column 12 is also installed at the upper end of the transmission frame 1, a third tube 15 is installed on one side of the first telescopic column 12, a second frame 11 is installed at the lower end of the first telescopic column 12, an eighth telescopic column 52 is installed at both ends of the second frame 11, and a seventh telescopic column 51 is installed at the lower end of the eighth telescopic column 52;

[0066] One of the marking devices 5 has four through sleeves 53, and the four through sleeves 53 are respectively connected to the eighth telescopic column 52 and the seventh telescopic column 51;

[0067] The first frame 10 is also installed on one side of the second frame 11 . The third electric push rod 59 is installed on one side of the first frame 10 . A horizontal bar 58 is installed on the lower end of the third electric push rod 59 . The upper end of the push column 50 is connected to the lower end of the horizontal bar 58 .

[0068] Two marking devices 5 are installed at the upper and lower ends of the transmission frame 1. One marking device 5 includes four through sleeves 53. Therefore, the outer diameter and inner diameter of the part are adapted through the eight through sleeves 53. Eight anti-cutting sheets 55 are slid out from the eight through sleeves 53 to fit the outer diameter and inner diameter of the upper and lower ends of the part. Therefore, during the next process, the sling will contact the anti-cutting sheet 55, so that the sling can avoid the edge of the part, thereby improving safety.

[0069] Since the parts are of different heights, the first telescopic column 12 drives the second frame 11 to adjust its position, and the second frame 11 drives the eighth telescopic column 52 and the seventh telescopic column 51 to move their positions, so that the through sleeve 53 is close to the parts, so that the anti-cutting sheet 55 can be accurately attached to the parts;

[0070] When the anti-cutting sheet 55 needs to fit the part, the third electric push rod 59 pushes the horizontal bar 58 to slide downward, and the horizontal bar 58 drives the push column 50 to slide downward, so that the push column 50 squeezes the anti-cutting sheet 55 through the through sleeve 53 to fit on the part;

[0071] It should be noted that the four eighth telescopic columns 52 and the through sleeves 53 connected to one side of the four eighth telescopic columns 52 are used to apply anti-cutting sheets 55 to the inner diameter of the parts;

[0072] It should be particularly noted that the four seventh telescopic columns 51 and the through sleeves 53 connected to one side of the four seventh telescopic columns 51 are used to provide anti-cutting sheets 55 on the outer diameter of the parts.

[0073] Embodiment 5:

[0074] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-Figure 7 A second inner diameter measuring device 7 is provided inside the rotating disk 32. The second inner diameter measuring device 7 includes a strip groove 72 provided inside the rotating disk 32. A vertical rod 76 is slidably connected inside the strip groove 72. The lower end of the vertical rod 76 penetrates the rotating disk 32. A second trapezoidal plate 40 is installed at one end of the first trapezoidal plate 34. The height of the second trapezoidal plate 40 is higher than that of the first trapezoidal plate 34. The vertical rod 76 is used to abut against the second trapezoidal plate 40.

[0075] The first trapezoidal block 71 is slidably connected inside the strip groove 72, and a plurality of first liquid storage chambers 74 are arranged on both sides of the first trapezoidal block 71. The plurality of first liquid storage chambers 74 are arranged in sequence, and the sizes of the plurality of first liquid storage chambers 74 gradually increase. The first extension plates 73 are slidably connected inside the plurality of first liquid storage chambers 74, and the lengths of the plurality of first extension plates 73 gradually increase. The first extension plates 73 are connected to the first trapezoidal block 71 through a second spring 75.

[0076] A second tube 14 is installed at one end of the first trapezoidal block 71 , the first liquid storage chamber 74 is connected to the second tube 14 , and the other end of the second tube 14 is connected to the eighth telescopic column 52 of one of the marking devices 5 .

[0077] according to Figure 2 As shown, when the rotating disk 32 rotates, the rotating disk 32 will also drive the vertical rod 76 to rotate, and the lower end of the vertical rod 76 will abut against the second trapezoidal plate 40, and the second trapezoidal plate 40 will squeeze the vertical rod 76 to slide upward. Since the height of the second trapezoidal plate 40 is higher than the height of the first trapezoidal plate 34, when the first trapezoidal plate 34 squeezes the support column 33 and the rotating disk 32 slides upward to the limit, the second trapezoidal plate 40 will squeeze the vertical rod 76 to continue to slide upward, so that the vertical rod 76 pushes the first trapezoidal block 71 to slide out of the interior of the strip groove 72, so that the first trapezoidal block 71 is inserted into the interior of the part. Figure 6 As shown, the length of the first extension plate 73 increases step by step, and the size of the first liquid storage cavity 74 increases gradually. The first extension plate 73 is provided with an inclined surface, so that several first liquid storage cavities 74 are trapezoidal. When the hole of the part touches any first extension plate 73, the first extension plate 73 slides to the inside of the first liquid storage cavity 74, and the first extension plate 73 is used to squeeze the liquid inside the first liquid storage cavity 74 to the second tube 14, and the liquid is transmitted to the inside of the eighth telescopic column 52 of the marking device 5 at the upper end of the transmission frame 1 through the second tube 14, so that the eighth telescopic column 52 pushes the through sleeve 53 on one side of the eighth telescopic column 52 to adjust the position, thereby realizing automatic detection of the inner diameter of the lower end of the part and automatically adjusting the position of the through sleeve 53 on one side of the eighth telescopic column 52;

[0078] It should be noted that, since the size of the first liquid storage chamber 74 is gradually increased, the amount of liquid squeezed out of each first extension plate 73 after being squeezed by the parts is different, so as to adapt to different inner diameters;

[0079] A first inner diameter measuring device 6 is also installed at the lower end of the second frame 11. The first inner diameter measuring device 6 includes a second trapezoidal block 61 connected to the lower end of the second frame 11. A plurality of second liquid storage chambers 63 are arranged inside the second trapezoidal block 61. A second extension plate 62 is slidably connected inside the second liquid storage chamber 63. The lengths of the plurality of second extension plates 62 are gradually shortened. The second extension plate 62 is connected to the second trapezoidal block 61 by a third spring 64. A first tube 13 is installed at one end of the second trapezoidal block 61. The first tube 13 is connected to the second liquid storage chamber 63. One end of the first tube 13 is connected to the seventh telescopic column 51 of another marking device 5.

[0080] according to Figure 2 As shown, since the first telescopic column 12 drives the second frame 11 to adjust its position, the first inner diameter measuring device 6 will be close to the upper end of the part. Figure 7 As shown, when the rotating disk 32 drives the part to slide upward, the first inner diameter measuring device 6 will be inserted into the upper end of the inner diameter of the part, so that the second trapezoidal block 61 is inserted into the interior of the part. Figure 7 As shown, the length of the second extending plate 62 increases step by step, and the size of the second liquid storage chamber 63 gradually increases. The lower end surface of the second extending plate 62 is provided with an inclined surface, so that several second extending plates 62 are trapezoidal. When the part hole touches any second extending plate 62, the second extending plate 62 slides to the inside of the second liquid storage chamber 63, and the second extending plate 62 is used to squeeze the liquid inside the second liquid storage chamber 63 to the first tube 13, and the liquid is transmitted to the inside of the eighth telescopic column 52 of the marking device 5 at the lower end of the transmission frame 1 through the first tube 13, so that the eighth telescopic column 52 pushes the through sleeve 53 on one side of the eighth telescopic column 52 to adjust the position, thereby realizing automatic detection of the inner diameter of the upper end of the part. In this way, in conjunction with Example 4, the inner diameter dimensions of the upper and lower ends of the part can be automatically detected, and the positions of the through sleeve 53 on one side of the eighth telescopic column 52 at the upper and lower ends can be adjusted, so that the four anti-cut sheets 55 can fit the parts with different inner diameter dimensions at the upper and lower ends.

[0081] Embodiment 6:

[0082] This embodiment is an improvement made on the basis of embodiment 5. For details, please refer to Figure 1-Figure 8 A detection device 8 is also installed at the upper end of the transmission frame 1. The detection device 8 includes a frame 80 installed at the upper end of the transmission frame 1. A force-bearing plate 81 is hinged on one side of the frame 80. A third telescopic column 82 and a sixth telescopic column 83 are installed on the other side of the frame 80. One side of the third telescopic column 82 and the sixth telescopic column 83 are both hinged to one side of the force-bearing plate 81.

[0083] An adjusting frame 85 is also installed at the upper end of the transmission frame 1, and a second electric push rod 90 is installed at one end of the adjusting frame 85. A slider 86 is slidably connected inside the adjusting frame 85, and a first electric push rod 87 is installed at one end of the slider 86. One end of the first electric push rod 87 and one end of the second electric push rod 90 are both connected to a fifth telescopic column 89. A fourth telescopic column 84 is installed at the upper end of the adjusting frame 85, and the upper end of the slider 86 is connected to the fourth telescopic column 84. A fourth tube 47 is connected to one side of the fifth telescopic column 89, and one end of the fourth tube 47 is connected to the inside of the second telescopic column 41. A connecting strip 88 is also installed at one side of the first electric push rod 87, and the second telescopic column 41 and the first electric push rod 87 are connected by the connecting strip 88.

[0084] One end of the third telescopic column 82 is connected to the transmission tube 16, and one end of the transmission tube 16 is connected to the inside of the fourth telescopic column 84;

[0085] One end of the sixth telescopic column 83 is connected to the third tube 15, and one end of the third tube 15 is connected to the inside of the first telescopic column 12;

[0086] One end of the fifth telescopic column 89 at one end of the first electric push rod 87 is also connected to a fifth tube, and the fifth tube is connected to the seventh telescopic column 51 of one of the marking devices 5;

[0087] One end of the fifth telescopic column 89 at one end of the second electric push rod 90 is connected to a sixth tube, and the sixth tube is connected to the seventh telescopic column 51 of another marking device 5 .

[0088] according to Figure 8 As shown, the operator places the parts on one side of the frame 80 by means of a crane and a sling, and then drives the parts to contact the force plate 81 by means of the electric roller 2. The force plate 81 rotates by squeezing the parts, and the force plate 81 squeezes the third telescopic column 82 and the sixth telescopic column 83, so that the liquid inside the third telescopic column 82 flows to the transmission pipe 16, and the liquid inside the sixth telescopic column 83 flows to the third pipe 15. Due to the different heights of the parts, the angles at which the parts squeeze the force plate 81 to rotate are also different, so parts of different heights squeeze different amounts of liquid;

[0089] according to Figure 8As shown, the liquid is squeezed to the fourth telescopic column 84 through the transmission pipe 16, and the slider 86 is driven to slide upward by the fourth telescopic column 84, and the slider 86 drives the first electric push rod 87 to slide upward, so that the first electric push rod 87 slides to the highest end of the part, and then the fifth telescopic column 89 is relatively pushed by the first electric push rod 87 and the second electric push rod 90, and the part is squeezed by the fifth telescopic column 89, so that the part is located at the center line of the electric roller 2, so that the part can slide to the upper end of the rotating disk 32 later, and then because the fifth telescopic column 89 can be extended and retracted, when the first electric push rod 87 slides to the limit, the part will squeeze the fifth telescopic column 89 on one side of the first electric push rod 87, so that the liquid inside the fifth telescopic column 89 is transmitted to the second telescopic column 41, thereby squeezing the inside of the second telescopic column 41, so that the second telescopic column 41 can push the square frame 42 to adjust its position, so that the outer diameter of the part is detected by the fifth telescopic column 89, and the position of the square frame 42 is adjusted, so that the convex thorn 46 can accurately contact the sling;

[0090] It should be noted that, since the sling node is at the upper end of the part, and the thorn 46 is located at the upper end surface of the motorized roller 2, the force of the thorn 46 pulling the sling will be damaged, affecting the effect of the sling being separated from the part. Therefore, when the first electric push rod 87 slides upward, the first electric push rod 87 will also drive the connecting strip 88 and the second telescopic column 41 to slide upward, so that the thorn 46 moves to the high point of the part, so that the thorn 46 can better tear the sling node, further improving the efficiency of the sling being separated from the part.

[0091] The liquid is transferred to the fifth tube and the sixth tube through the four fifth telescopic columns 89, and the fifth tube and the sixth tube are used to squeeze the liquid to the seventh telescopic column 51, so as to adjust the position of the through sleeve 53 on one side of the seventh telescopic column 51, thereby automatically detecting the diameters of the upper and lower ends of the part and adjusting the position of the through sleeve 53. In this way, in conjunction with Example 5, the eight through sleeves 53 can accurately slide out the anti-cut sheet 55 to fit the upper and lower outer diameters and inner diameters of the part;

[0092] The third telescopic column 82, the sixth telescopic column 83, the fourth telescopic column 84, the fifth telescopic column 89, the second electric push rod 90, the second telescopic column 41 and the first telescopic column 12 all include a piston cylinder, a piston rod and a return spring, the piston cylinder is provided with a piston rod, and the piston rod is connected to the piston cylinder via a return spring;

[0093] Electromagnetic one-way valves are provided inside the third telescopic column 82, the sixth telescopic column 83, the fourth telescopic column 84, the fifth telescopic column 89, the second telescopic column 41, the seventh telescopic column 51, the eighth telescopic column 52 and the first telescopic column 12. A button 17 is also installed at the upper end of the transmission frame 1, and the button 17 is electrically connected to a plurality of electric valves.

[0094] When the liquid enters the third telescopic column 82, the sixth telescopic column 83, the fourth telescopic column 84, the fifth telescopic column 89, the second telescopic column 41, the seventh telescopic column 51, the eighth telescopic column 52 and the first telescopic column 12, the electric valves are closed to ensure that the third telescopic column 82, the sixth telescopic column 83, the fourth telescopic column 84, the fifth telescopic column 89, the second telescopic column 41, the seventh telescopic column 51, the eighth telescopic column 52 and the first telescopic column 12 will not reset. Subsequently, when the anti-cut sheet 55 is fitted to the parts, the parts are transmitted through the electric roller 2. When the parts hit the button 17, all the electromagnetic one-way valves are energized, so that the liquid inside the third telescopic column 82, the sixth telescopic column 83, the fourth telescopic column 84, the fifth telescopic column 89, the second telescopic column 41, the seventh telescopic column 51, the eighth telescopic column 52 and the first telescopic column 12 is pulled to reset by the reset spring.

[0096] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
