Description

Technical Field

[0001] The utility model relates to the technical field of paper shredders, in particular to a blade stacking machine. Background Art

[0002] The shredder is composed of a set of rotating blades, a paper comb and a driving motor. Paper is fed in from the middle of the interlocking blades and is cut into many small pieces of paper to achieve the purpose of confidentiality. The blade of the shredder is assembled by stacking multiple blades and sleeved on the blade shaft, and the blade shaft is also sleeved with a spacer ring between two blades. Usually, when the blade stacking equipment is working, the blade is grabbed by the manipulator to the top of the vertical blade shaft, and then the blade is vertically moved down and sleeved on the blade shaft. The blade shaft passes through the center hole of the blade to complete the stacking. Since the front and back sides of the blades are different, it is necessary to manually screen and distinguish the front and back sides of the blades when assembling the shredder, so as to ensure that all blades are installed on the iron rod as the blade shaft with the same side facing up. The labor consumption is large, and the workers are very easy to fatigue. In addition, there are sharp corners on the blades, which are easy to stab the hands during manual sorting. There are problems such as low assembly efficiency and poor precision of finished products. Therefore, a stacking machine that automatically assembles blades and spacer rings is urgently needed.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0031] In this embodiment, Figure 1 As shown, it includes a mounting frame 1, on which a flexible vibration plate 2, a visual recognition mechanism 12, a manipulator 3, a positioning mechanism 10 and a clamping mechanism 11 are provided.

[0032] The specific structure is that a flexible vibration plate 2 and a manipulator 3 are provided on the mounting frame 1, a shock absorbing platform 4 is provided on the mounting frame 1, the flexible vibration plate 2 includes a base 21, a material tray 22 and a cover plate 24, the base 21 is a box-shaped hollow structure with an opening at the top, of course, the base 21 can also be a rectangular support structure formed by four plate-like structures. In this embodiment, the base 21 is installed on the shock absorbing platform 4, the top opening of the base 21 faces upward, a cover plate 24 is provided at the opening, the material tray 22 is installed on the cover plate 24, a motor seat 25 is provided inside the base 21, and four motor seats 25 are fixed in the base 21 and are located on the cover plate 24, a voice coil motor 26 is provided on the top of the motor seat 25, and a controller is also provided in the base 21. The controller is electrically or pneumatically connected to the voice coil motor 26, and the controller is used to control the operation of the voice coil motor 26. The motor seat 25 is used to fix the voice coil motor 26. The top of the voice coil motor 26 is in contact with the bottom of the cover plate 24. The material tray 22 is fixed on the cover plate 24 by fasteners or limiters, that is, the cover plate 24 is installed on the output end of the voice coil motor 26. The movement of the voice coil motor 26 drives the cover plate 24 to vibrate, and the cover plate 24 drives the material tray 22 to vibrate, so that the stacked blades 23 in the material tray 22 are spread out.

[0033] It should be noted that the motor seat 25 is provided with fixing holes at the four corners extending outward, and fasteners such as bolts or screws are installed in the fixing holes, so that the motor seat 25 can be detachably fixed to the bottom of the base 21.

[0034] It should be noted that the material tray 22 can be made of a flexible material, such as PE, PP, PVC or PU, which has a smooth surface and high toughness to prevent the blade 23 from being damaged when the inner wall of the material tray collides with the blade 23.

[0035] A feeding mechanism 5 is also provided on the shock absorbing platform 4. In the present embodiment, the feeding mechanism 5 is mainly a loading platform on which a large number of blades 23 can be placed. A guide opening is extended from the loading platform above the material tray 22, and the blades 23 fall into the material tray 22 from the guide opening.

[0036] In this embodiment, the shock absorbing platform 4 is a frame structure, which is fixed on the mounting frame 1. The top of the frame structure is a mounting platform, and a rubber pad for shock absorption is provided on the mounting platform, so that the shock absorbing platform 4 can play a certain shock absorbing role on the base 21 and the feeding mechanism 5, and can also adjust the positional relationship between the feeding mechanism 5 and the material tray 22.

[0037] The utility model also includes a manipulator 3, which includes a first host 31 installed on the mounting frame 1, and a connecting arm 32 is rotatably connected to the first host 31. The connecting arm 32 is horizontally placed and one end of the connecting arm 32 is connected to the first host 31 through a vertical rotating shaft. The first host 31 drives the connecting arm 32 to rotate horizontally around the rotating shaft, and the other end of the connecting arm 32 is connected to the second host 33 through another rotating shaft, so that the second host 33 drives itself to rotate around the connecting arm 32, that is, the first host 31 drives the connecting arm 32 to rotate, and the connecting arm 32 can drive the second host 33 to rotate, and at the same time, the second host 33 can rotate along the connecting arm 32, thereby realizing reciprocating movement in the X-axis direction.

[0038] The second host 33 is provided with a lifting shaft 34, and the second host 33 drives the lifting shaft 34 to perform lifting and rotation movements. A gripping portion is provided at the end of the lifting shaft 34, and the gripping portion includes a rotating disk 35, which is fixed to the end of the lifting shaft 34, so that the rotating disk 35 can perform both lifting and rotating movements. A strong magnetic suction cup 36 is provided at the bottom of the rotating disk 35, and the strong magnetic suction cup 36 rotates and lifts with the rotating disk 35. In this embodiment, a groove is provided on the bottom end surface of the strong magnetic suction cup 36, that is, the strong magnetic suction cup 36 is annular in structure, and a hole is provided in the middle of the groove of the strong magnetic suction cup 36, and a pushing column 37 is inserted in the hole, one end of the pushing column 37 is connected to the lifting shaft 34, and the other end passes through the hole. When the strong magnetic suction cup 36 is adsorbed to the upper end surface of the blade 23 in the material tray 22 and the blade 23 is transferred to a predetermined position, the pushing column 37 pushes the central position of the end surface of the blade 23 under the lifting action of the lifting shaft 34, so that the blade 23 is separated from the strong magnetic suction cup 36.

[0039] An elastic element is also provided between the base 21 and the cover plate 24, and the elastic element includes a spring 29, a first limit seat 27 and a second limit seat 28. The first limit seat 27 and the second limit seat 28 are coaxially arranged on the base 21 and the cover plate 24, that is, the first limit seat 27 and the second limit seat 28 are arranged opposite to each other, one end of the spring 29 is sleeved on the first limit seat 27, and the other end is sleeved on the second limit seat 28. It should be noted that there is a certain height difference between the cover plate 24 and the base 21, so that the spring 29 can play a certain buffering and shock-absorbing role after the cover plate 24 is compressed. When the grasping part of the manipulator 3 absorbs the blade 23 in the material tray 22, the strong magnetic suction cup 36 moves to the upward end face of the blade 23 and contacts it. Since the flexible vibration disk 2 is always in a vibrating state, when the strong magnetic suction cup 36 absorbs the blade 23, the vibrating material tray 22 collides with the strong magnetic suction cup 36 at the moment when the strong magnetic suction cup 36 contacts the blade 23, so that high-frequency hard collisions will occur among the strong magnetic suction cup 36, the blade 23 and the bottom of the material tray 22, which may damage the blade 23 in severe cases. Therefore, the strong magnetic suction cup 36 will immediately press down the material tray 22 after absorbing the blade 23, so that the material tray 22 will not have a hard collision with the absorbed blade 23 under the action of the spring 29 during the vibration process, because the spring 29 plays a certain buffering and shock-absorbing role, and then the grasping part is driven by the manipulator 3 and immediately separated from the material tray 22, thereby completing the material removal in the material tray 22.

[0040] In this embodiment, there are two shock absorbing platforms 4, which are symmetrically distributed on both sides of the manipulator 3. Two flexible vibration disks 2 are provided on each shock absorbing platform 4. In this embodiment, two flexible vibration disks 2 are provided on one shock absorbing platform 4. The two flexible vibration disks 2 are arranged side by side, which is very convenient for the manipulator 3 to move left and right to grab under the action of the first main unit 31 and the connecting arm 32. Different types of blades 23 can be placed in different flexible vibration disks 2, which greatly improves the material collection efficiency. The first main unit 31 and the second main unit 33 of the manipulator 3 usually use cylinders or electric cylinders as driving forces, which are centrally controlled by the control center. The above-mentioned controller, the first main unit 31 and the second main unit 33 are all conventional products on the market, and the specific structure and working principle are not repeated here.

[0041] The visual recognition mechanism 12 is arranged in a one-to-one correspondence with the flexible vibration disk 2. The visual recognition mechanism 12 mainly includes a camera, which is connected to the control center of the whole machine. The camera is located directly above each flexible vibration disk 2 to shoot the upper surface of the blade 23 in the flexible vibration disk 2. In this embodiment, a mark is engraved on the front or back of the blade 23. The camera is aimed at the upper surface of the blade 23 to obtain image information of the upper surface of the blade 23, and the obtained image information is fed back to the control center. For example, the marked side of the blade 23 is defined as the front side, and the blade 23 falling from the storage box is in two states: front side facing up or back side facing up. When the control center knows according to the image information that there is no blade 23 facing up in the flexible vibration disk 2, the control center controls the flexible vibration disk 2 to vibrate, and flips the blade 23 from the back side facing up to the front side facing up, so as to perform repeated continuous vibration.

[0042] The positioning mechanism 10 includes two mounting seats 10191 slidably connected to the mounting frame 1, and each mounting seat 10191 is detachably provided with a base 102, and a vertical knife shaft 103 is provided on the base 102. In this embodiment, the base 102 is provided with a plurality of mounting holes 104 that can be used to install knife shafts 103 of different models, and the mounting holes 104 are usually polygonal holes fixedly matched with the knife shaft 103, so that the knife shaft 103 can be detachably connected, and multiple knife shafts 103 can be stacked with blades 23 at the same time.

[0043] A third linear guide rail is provided on the mounting frame 1, and a sliding groove that slides with the third linear guide rail is provided at the bottom of the mounting seat 10191. A lead screw pair is provided between the mounting seat 10191 and the mounting frame 1. The mounting seat 10191 slides back and forth along the third linear guide rail driven by the lead screw pair. Two mounting seats 10191 are provided on the same linear guide rail in sequence. After the blade 23 and the spacer ring 116 are installed on the knife shaft 103 of one of the mounting seats 10191, it moves to one side, and the other mounting seat 10191 moves to the installation position for installation, so that the assembly work of the blade 23 can be carried out continuously and automatically, thereby improving the assembly efficiency.

A through hole 1110 is opened at the central position of the bottom of the first slide groove 113. A vertical limiting column 114 is provided in the through hole 1110. A driving member for driving the limiting column 114 to perform a telescopic action is provided at the bottom of the first slide groove 113. The push rod 117 moves the spacing ring 116 enters the through hole 1110 in the first slide groove 113 from the second slide groove 115, and at this time, the limit column 114 rises and is inserted into the center hole of the spacer ring 116 to position the spacer ring 116. Then, the positioning plate 112 moves from position 1 to position 2 under the push of the telescopic cylinder 119. The positioning seat 111 is slidably connected with a fixed seat at position 2. The sliding mode of the fixed seat is also realized by combining a linear guide rail and a driving member. The fixed seat moves toward the positioning plate 112 at the second position. A claw-shaped chuck 118 is provided on the fixed seat. The chuck 118 moves with the fixed seat to above the first slide groove 113 of the positioning plate 112. At this time, the limit column 114 descends, and the claw-shaped chuck 118 clamps the spacer ring 116 and moves along the first slide groove 113 driven by the fixed seat to grab the spacer ring 116 to above the knife shaft 103. In this embodiment, the positioning mechanism 10 is located exactly between the manipulator 3 and the clamping mechanism 11, so the claw-shaped chuck 118 can translate along the first slide groove 113 to reach above the knife shaft 103, and the spacer ring 116 can be directly mounted on the knife shaft 103.

[0045] The positioning plate 112 is provided with a first slide groove 113, and a vertically retractable limit column 114 is provided at the central position of the first slide groove 113.

The positioning plate 112 is also provided with a pushing rod 117 for pushing the spacer ring 116 in the second slide groove 115 to the first slide groove 113. The positioning seat 111 is provided with a claw chuck 118 for grabbing the spacer ring 116 in the first slide groove 113 and inserting it into the knife shaft 103 above the other side of the positioning plate 112.

[0046] The mounting frame 1 is also provided with a pressing mechanism, which includes a lifting mechanism 8, a horizontal lateral movement mechanism 9 and a pressing portion 6. The lifting mechanism 8 includes a bracket 81 and a first lead screw 82 located on the bracket 81. The first lead screw 82 is vertically arranged. The bracket 81 is provided with a first driving device 83 for driving the first lead screw 82 to rotate. The first lead screw 82 is slidably fitted with a first slider 84. The first slider 84 makes vertical reciprocating motion along the first lead screw 82 relative to the bracket 81.

[0047] The horizontal traverse mechanism 9 includes a mounting seat 10191 fixed on the first slider 84. The mounting seat 10191 moves vertically up and down along the bracket 81 with the first slider 84. The mounting seat 10191 is provided with a left-right screw 92. The left-right screw 92 is arranged vertically relative to the first screw 82. The mounting seat 10191 is provided with a second driving device 93 for driving the left-right screw 92 to rotate. There are two second sliders 94 slidingly matched on the left-right screw 92, so that the second slider 94 can move along the left-right screw 9 2 is horizontally reciprocating and translated, and at the same time, is vertically lifted and lowered by the lifting mechanism 8. Since the two second sliders 94 are sequentially mounted on the same left-right rotating lead screw 92, which is a bidirectional lead screw, the lead screw rotates in one direction, and the two second sliders 94 matched on the lead screw separate or move together at both ends. When the lead screw rotates in the opposite direction, the two second sliders 94 move together or separate. The number of the pressing parts 6 is two, which are respectively mounted on the two second sliders 94, so that the two pressing parts 6 can reciprocate and translate relative to each other.

[0048] The pressing part 6 is located directly above the base 102, that is, above the knife shaft 103.

That is, the two pressing parts 6 are symmetrically close to the sides of the knife shaft 103 on the opposite surfaces of the two pressing parts 6. That is, the pressing part 6 is moved by the lifting mechanism 8 and the horizontal traverse mechanism 9. The horizontal transverse movement mechanism 9 jointly drives the blade 23 to move down to both sides of the top of the blade shaft 103. Before the downward pressure part 6 moves, the blade 23 on the blade shaft 103 is stuck on the shaft body of the blade shaft 103 during the sleeve installation process, and does not smoothly fall to the bottom of the blade shaft 103 to form a stack. The downward pressure part 6 moves from both sides of the blade shaft 103 from top to bottom until the downward pressure part 6 contacts the upper end surface of the blade 23 stuck on the shaft body of the blade shaft 103. The downward pressure part 6 continues to descend, thereby pressing the blade 23 downward, and finally the blade 23 will smoothly fall to the bottom of the blade shaft 103 to form a normal stack.

[0049] In addition, a first linear guide 85 is provided on the bracket 81 along the transmission direction of the first lead screw 82, and a first slide groove 113 is provided on the first slider 84 for sliding cooperation with the first linear guide 85, so that the first slider 84 can move stably; a second linear guide 95 is provided on the mounting seat 10191 along the transmission direction of the left and right rotating lead screw 92, and a second slide groove 115 is provided on the second slider 94 for sliding cooperation with the second linear guide 95, so that the second slider 94 can move stably.
