Description

Technical Field

[0001] The invention relates to the technical field of rapid stacking of metal cans, in particular to a metal can interlayer stacking system with stably arranged felt paper. Background Art

[0002] When metal cans are being stacked and packaged, in order to ensure the stability of each layer of metal cans, it is necessary to isolate them with felt paper before stacking each layer of metal cans, and the presence of felt paper can provide a horizontal placement surface, thereby ensuring the stability of the metal cans after stacking. For stacking efficiency considerations, the existing felt paper layout is generally carried out simultaneously with the stacking and placement of metal cans. When the metal cans are lifted from the top of the conveying mechanism and moved to the top of the pallet and placed, the felt paper can be adsorbed by the felt paper absorber and pulled to the top of the metal can layer during the process of moving the layout mechanism to the conveying mechanism, thereby completing the felt paper placement and realizing automation. However, during the use of the above system, there is an unexpected situation, that is, the felt paper falls from the bottom of the felt paper absorber midway, which will cause the felt paper placement position to be wrong, thereby affecting the packaging of the entire metal can stack, and when the above situation occurs, it cannot be detected. Even if it can be detected at the first time, since the position of the felt paper is not fixed, it is impossible to handle the accident through the above system, so it needs to be solved manually, that is, the felt paper is manually reset or placed, for this purpose, the entire machine needs to be shut down. Summary of the invention

[0003] In order to solve the problem that the above-mentioned system for processing felt paper due to mid-falling is unable to process the felt paper and enable the production line to operate normally, the present invention provides a metal can interlayer stacking system for stably arranging felt paper.

[0004] The technical solution of the present invention is as follows:

[0005] A metal can interlayer stacking system for stably arranging felt paper comprises a conveying mechanism, a lifting mechanism and a felt paper driving mechanism arranged in a straight line direction;

[0006] The lifting mechanism is provided with a horizontal and movable tray, a reciprocating arrangement mechanism is provided above the end of the conveying mechanism, and the reciprocating arrangement mechanism can move to the top of the lifting mechanism and place the metal can on the tray, and a felt paper absorber is provided at one end of the reciprocating arrangement mechanism close to the felt paper driving mechanism, and when the reciprocating arrangement mechanism moves to just above the tray, the felt paper absorber is located above the end of the felt paper driving mechanism close to the lifting mechanism;

[0007] A felt paper feeding mechanism is arranged at one end of the felt paper driving mechanism away from the lifting mechanism, and a limit frame is symmetrically arranged on the felt paper driving mechanism along the moving direction of the felt paper, and a follower type resetter is arranged above the limit frame, and the follower type resetter can move along the direction of the felt paper;

[0008] A compensating placer is arranged above the felt paper driving mechanism, and the compensating placer comprises guide beams symmetrically arranged along the moving direction of the felt paper, and a movable rail beam capable of moving along the moving direction of the felt paper is arranged across the guide beams, and a plurality of placing telescopic members are arranged at intervals along the length direction of the movable rail beam, and the lower end of the placing telescopic member is inclined toward the lifting mechanism;

[0009] The placement telescopic member can be moved to the top of the tray, and the minimum spacing between the placement telescopic member and the felt paper absorber in the horizontal direction is greater than 0;

[0010] The felt paper absorber is also provided with a distance meter, and the distance meter is used to detect the vertical distance between the felt paper absorber and the felt paper.

[0011] On the basis of the existing structure, by adding a rangefinder to sense the felt paper, it can be detected in time if the felt paper falls during the movement process, and by setting a follow-up resetter, the felt paper can be reset, so there is no need to manually handle the felt paper, and there is no need to shut down the entire machine. Moreover, the felt paper can be automatically re-placed by means of a compensating placer.

[0012] The specific structure of the above-mentioned reciprocating arranging mechanism is that the reciprocating arranging mechanism includes a reciprocating moving frame that can move along the length direction of the conveying mechanism, the reciprocating moving frame is provided with two metal can lifters spaced apart along the length direction of the conveying mechanism, and the metal can lifters can be raised and lowered, and the felt paper absorber is not arranged between the two metal can lifters.

[0013] The method for realizing felt paper monitoring is that the felt paper absorber can be raised and lowered relative to the reciprocating moving frame, and the felt paper absorber includes a horizontally arranged cross plate, the cross plate is perpendicular to the moving direction of the felt paper absorber and flexible suction cups for absorbing felt paper are arranged below both ends, the cross plate is also provided with a vertical detection hole, the detection hole is located between the two flexible suction cups and a rangefinder is arranged.

[0014] The specific structure of the above-mentioned follower resetter is that the follower resetter includes a fixed guide frame fixed above the limit frame, and the length direction of the fixed guide frame is the same as the moving direction of the felt paper, and the fixed guide frame is provided with a telescopic member that can move along the length direction, and the telescopic member is located on the side of the fixed guide frame close to the felt paper and is vertically arranged, and the output end of the telescopic member is provided with a follower suction cup. Through the arrangement of the follower suction cup, synchronous follow-up movement can be achieved during the movement of the felt paper, and if the felt paper falls off midway, through the action of the follower suction cup, in conjunction with the horizontal movement of the telescopic member, the felt paper can be reset and facilitated to be placed normally later.

[0015] The method for realizing the movement of the telescopic part is that the fixed guide frame is provided with a long hole along the length direction, and a moving seat is provided in the long hole, and the telescopic part is fixed on one side of the moving seat, and a driver is provided on the other side. The driver is a motor, and a gear is provided at the output end. The fixed guide frame is provided with a rack along the length direction to mesh with the gear.

[0016] In order to quickly reset the felt paper, the telescopic member is configured to move away from the lifting mechanism immediately after the rangefinder exceeds a preset threshold until it is reset. After the reset, the felt paper is equivalent to not moving, and the reciprocating arrangement mechanism is still lifting the metal can normally, so the felt paper can continue to be placed during this period of time.

[0017] The normal operation mode of the telescopic member and the follower suction cup is that the horizontal movement stroke of the telescopic member is smaller than the horizontal movement stroke of the felt paper absorber, and the telescopic member and the follower suction cup are arranged to work after the felt paper absorber moves to the farthest position away from the conveying mechanism and can stop working after the telescopic member reaches the minimum horizontal distance with the lifting mechanism, and the telescopic member can immediately move in the direction away from the lifting mechanism until it is reset after reaching the minimum horizontal distance with the lifting mechanism.

[0018] In order to avoid collisions between devices, the flexible suction cup can be released from the negative pressure state after the rangefinder exceeds the preset threshold, and the reciprocating arrangement mechanism cannot move toward the felt paper driving mechanism before the telescopic member and the follow-up suction cup stop working. When the felt paper falls, the flexible suction cup needs to stop and avoid affecting subsequent operations. During the reset process of the felt paper, the second stacking of metal cans is avoided to ensure that the felt paper can be placed normally.

[0019] In order to lay the felt paper normally, the compensation placement device can be started after the telescopic member and the follower suction cup reach the reset position in the working state. At this time, the telescopic member needs to extend and absorb the felt paper, and then the moving rail beam moves toward the lifting mechanism until the felt paper is placed in the specified position and reset.

[0020] In order to quickly rearrange the felt paper, the speed at which the telescopic member moves away from the lifting mechanism is greater than the moving speed of the reciprocating arranging mechanism.

[0021] The beneficial effects of the present invention are as follows: the present invention is a metal can interlayer stacking system for stably arranging felt paper, and a follower-type resetter and a compensating placer are added on the basis of the existing structure, and the felt paper placement work is monitored by arranging a rangefinder at the felt paper absorber. When the rangefinder exceeds the threshold value, it means that the felt paper falls prematurely before being placed at the specified position. At this time, the felt paper can be reset by the follower-type resetter and the compensating placer can be used to re-place the felt paper without affecting the operation of the reciprocating arranging mechanism, thereby being able to repair unexpected problems occurring in the above-mentioned production line without manpower.

[0033] Example

[0034] like Figure 1-4 The metal can interlayer stacking system with stably arranged felt paper shown in the figure comprises a conveying mechanism 1, a lifting mechanism 3 and a felt paper driving mechanism 4 arranged in a straight line direction, wherein the conveying mechanism 1 is used to transport the metal cans, and the relevant structure is introduced in the documents previously applied for by the company, so it is not repeated here, and the lifting mechanism 3 is used to set the tray, and the tray is continuously lowered as the metal cans are stacked, ensuring that the metal cans are placed in the preset position each time they are stacked, so that the reciprocating stacking operation with a fixed path can be realized, which is very convenient, and finally the felt paper driving mechanism 4, the felt paper driving mechanism The structure 4 is used to move the felt paper to a position convenient for grabbing, and the felt paper driving mechanism 4 includes a horizontal placement plate, and two grooves are symmetrically provided on the placement plate along the moving direction of the felt paper, and a pusher capable of moving along the length direction of the groove is arranged in the groove, and the pusher is driven by a motor and reciprocates along the length direction of the groove, and the top of the pusher is higher than the upper surface of the placement plate, so after the felt paper feeding mechanism moves the felt paper from the felt paper pile to the placement plate, it can push the felt paper forward and move it to a position convenient for grabbing, and in the above manner, automatic layout of the felt paper can be realized.

[0035] Afterwards, the lifting mechanism 3 is provided with a horizontal and movable tray. The horizontal setting ensures that the metal can will not fall over after being placed, and a reciprocating arranging mechanism 2 is arranged above the end of the conveying mechanism 1. The reciprocating arranging mechanism 2 is used to lift the metal can from the end of the conveying mechanism 1 and move it to the top of the lifting mechanism 3 and place the metal can on the tray. At the same time, a felt paper absorber 23 is arranged at one end of the reciprocating arranging mechanism 2 close to the felt paper driving mechanism 4. When the reciprocating arranging mechanism 2 moves to just above the tray, the felt paper absorber 23 is located above the end of the felt paper driving mechanism 4 close to the lifting mechanism 3. At this time, the felt paper absorber 23 can absorb one end of the felt paper and pull the felt paper 7 and place it above the metal can layer as the reciprocating arranging mechanism 2 moves to the conveying mechanism 1.

[0036] like Figure 5As shown, the specific structure of the above-mentioned reciprocating arrangement mechanism 2 is that the reciprocating arrangement mechanism 2 includes a reciprocating frame 21 that can move along the length direction of the conveying mechanism 1, and the reciprocating frame 21 is provided with two metal can lifters 22 at intervals along the length direction of the conveying mechanism 1. The structure of the metal can lifter 22 is a public structure, and its specific principle is not repeated. It should be noted that the metal can lifter 22 can be raised and lowered, and its lifting is independently arranged relative to the reciprocating frame 2, that is, it does not affect other structures. Then, the felt paper absorber 23 is not arranged between the two metal can lifters 22 to avoid interference with the lifting of the metal can, and it can also complete the absorption of the felt paper during the lifting process of the metal can. Figure 5 As shown, the felt paper absorber 23 is arranged near the end, and is arranged near the end of the lifting mechanism.

[0037] Only through the above structure, the original metal can lifting and felt paper laying operations can be realized. In order to monitor the laying of felt paper, the following structure needs to be set up.

[0038] like Figure 5As shown, the way to realize the monitoring of the felt paper 7 is that the felt paper absorber 23 can be raised and lowered relative to the reciprocating frame 21, that is, it can be lowered to absorb the felt paper and then lift it up and move with the reciprocating frame 21, and the felt paper absorber 23 includes a horizontally arranged cross plate, the horizontal cross plate can be used in conjunction with the horizontally arranged felt paper, and the cross plate is perpendicular to the moving direction of the felt paper absorber 23 and flexible suction cups 231 for absorbing the felt paper 7 are arranged below both ends, and the flexible suction cups 231 can absorb the felt paper and then move it under negative pressure, and it should be emphasized that the cross plate is also provided with a vertical detection hole 232, and the detection hole 232 is located between the two flexible suction cups 231 and is arranged A rangefinder is provided, wherein the rangefinder is not shown in the figure, because it can be directly purchased, and the relevant structure and principle are not described in detail. It should be noted that by setting the rangefinder vertically downward and cooperating with the detection hole 232, the felt paper below can be monitored. When the flexible suction cup 231 is under negative pressure, if the reading of the rangefinder changes, it proves that the felt paper has fallen. If the reading of the rangefinder is normal during the entire movement process of the flexible suction cup 231 under negative pressure, it means that the felt paper is moving normally, that is, the equipment is operating normally. At this time, no operation is required, and the equipment can operate normally, and the setting of the rangefinder will not affect the normal use of the equipment. Structurally, the felt paper absorber 23 is also provided with a rangefinder, and the rangefinder is used to detect the vertical distance between the felt paper absorber 23 and the felt paper 7. If the value of the vertical spacing is within the threshold value when the flexible suction cup 231 is under negative pressure, it proves that the equipment is operating normally. Otherwise, it proves that the felt paper has fallen off. Moreover, since multiple rangefinders can be set up, any problem with any one of them can prove that the felt paper has fallen off. Dragging one end of the felt paper may also cause the felt paper to rotate or other problems. Therefore, the best choice is the method of the present invention, in which the felt paper is reset and replaced.

[0039] And, if Figure 3 , 4 As shown, a felt paper feeding mechanism is arranged at one end of the felt paper driving mechanism 4 away from the lifting mechanism 3, which is used to move the felt paper to the position of the felt paper driving mechanism 4. Its structure is a public structure and therefore will not be described in detail. It should be noted that the felt paper driving mechanism 4 is symmetrically provided with limit frames along the moving direction of the felt paper 7. The setting of the limit frames can ensure that the felt paper moves in a straight line, thereby avoiding rotation. However, the felt paper cannot be reset by the above structure alone. For this reason, another important structure of the present invention is that, Figure 6 , 7As shown, a follower resetter 5 is arranged above the limit frame, and the follower resetter 5 can move along the direction of the felt paper 7, and the moving path is reciprocating, and the specific structure of the follower resetter 5 is that the follower resetter 5 includes a fixed guide frame 51 fixed above the limit frame, the fixed guide frame 51 can be regarded as a guide rail structure, and the length direction of the fixed guide frame 51 is the same as the moving direction of the felt paper 7, so its guide path is the same as the moving path of the felt paper 7, then, the fixed guide frame 51 is provided with a telescopic member 55 that can move along the length direction, the telescopic member 55 can be a cylinder or an electric cylinder, and its output direction is vertically arranged to ensure that the output end can be close to or away from the felt paper 7, that is, the telescopic member 55 is located on the side of the fixed guide frame 51 close to the felt paper 7 and is vertically arranged, and then the output end of the telescopic member 55 is provided with a follower suction cup 56. By setting the following suction cup 56, after the telescopic part 55 is extended, the felt paper can be adsorbed by the following suction cup 56, so that the synchronous following movement can be realized during the movement of the felt paper 7. If the felt paper 7 falls off in the middle, since the following suction cup 56 still adsorbs the felt paper, if the following suction cup 56 is moved, the felt paper can be pulled to move. Therefore, through the action of the following suction cup 56 and the horizontal movement of the telescopic part 55, the felt paper 7 can be reset and it is convenient for normal placement later.

[0040] In the above structure, it should be noted that in order to avoid collision between devices, the flexible suction cup 231 can be closed after the rangefinder exceeds the preset threshold, that is, in the process of actively driving the felt paper to move by the following suction cup 56, the above flexible suction cup 231 cannot absorb the felt paper to avoid the phenomenon of tearing of the felt paper due to the driving of the two different structures, and the reciprocating arrangement mechanism 2 cannot move in the direction close to the felt paper driving mechanism 4 before the telescopic member 55 and the following suction cup 56 stop working, that is, the above reciprocating arrangement mechanism 2 only needs to separate the flexible suction cup 231 from the negative pressure state to perform all subsequent actions, including lifting the metal can. The purpose is that when the felt paper 7 falls, the flexible suction cup 231 needs to stop and avoid affecting the subsequent operation, and in the process of resetting the felt paper 7, avoid stacking the metal can for the second time to ensure that the felt paper 7 can be placed normally. Ensure that during the process of re-arranging the felt paper, the equipment is disordered and the metal can cannot be stacked normally.

[0041] Moreover, in the above structure, Figure 7As shown, the method for realizing the movement of the telescopic member 55 is that the fixed guide frame 51 is provided with a long hole along the length direction, and a moving seat 52 is provided in the long hole, and the telescopic member 55 is fixed on one side of the moving seat 52, and a driver 53 is provided on the other side. The driver 53 is a motor, and a gear is provided at the output end. The fixed guide frame 51 is provided with a rack 54 along the length direction to mesh with the gear. By rotating the driver 53, the gear can be moved along the rack 54, thereby providing power to retract the felt paper. In a normal state, the felt paper can drag the moving seat 52 to move, and the gear provided on the driver 53 is passively rotated.

[0042] In order to quickly reset the felt paper 7, the telescopic member 55 can move away from the lifting mechanism 3 immediately after the rangefinder exceeds the preset threshold until it is reset. After the reset, the felt paper 7 is equivalent to not moving, and the reciprocating arrangement mechanism 2 is still lifting the metal can normally. Therefore, during this period of time, the placement of the felt paper 7 can continue. As long as the felt paper is re-arranged within this period of time, the equipment can continue to operate without stopping, and will not cause any negative impact on the stacking efficiency. If it cannot be completed within this period of time, some mechanisms need to be stopped and waited to avoid collision between structures.

[0043] In view of the above two situations, the normal operation mode of the telescopic member 55 and the follower suction cup 56 is that the horizontal movement stroke of the telescopic member 55 is smaller than the horizontal movement stroke of the felt paper absorber 23, that is, before the felt paper 7 is placed, the telescopic member 55 can reach the limit position, at which time the return action can be performed, and the telescopic member 55 and the follower suction cup 56 are arranged to work after the felt paper absorber 23 moves to the farthest position away from the conveying mechanism 1 and can stop working after reaching the minimum horizontal distance from the lifting mechanism 3. First, when the felt paper absorber 23 moves to the farthest position away from the conveying mechanism 1, the telescopic member 55 and the follower suction cup 56 can stop working after reaching the minimum horizontal distance from the lifting mechanism 3. After the appendage 23 moves to the farthest position away from the conveying mechanism 1, it means that the felt paper 7 needs to be adsorbed and placed. At this time, the follower suction cup 56 needs to adsorb the felt paper and move synchronously with it. When the telescopic member 55 reaches the extreme position after reaching the minimum horizontal distance from the lifting mechanism 3, the follower suction cup 56 needs to be released from the negative pressure state, and the telescopic member 55 needs to be retracted and return, that is, after reaching the minimum horizontal distance from the lifting mechanism 3, it immediately moves in the direction away from the lifting mechanism 3 until it is reset, so as to wait for the normal placement of the subsequent felt paper 7.

[0044] Finally, since the reciprocating laying mechanism 2 will not re-lay out the reset felt paper, the last important structure of the present invention is that a structure for laying felt paper needs to be provided, that is, a compensation placer 6 is provided above the felt paper driving mechanism 4, and the compensation placer 6 includes guide beams 61 symmetrically arranged along the moving direction of the felt paper 7, and a movable rail beam 62 that can move along the moving direction of the felt paper 7 is arranged across the guide beams 61, and the movement of the movable rail beam 62 can realize the movement of the felt paper. For this reason, the movable rail beam 62 is provided with a plurality of placement telescopic parts 63 at intervals along the length direction, and the lower end of the placement telescopic part is inclined toward the lifting mechanism 3, wherein the placement telescopic part 63 includes a telescopic cylinder and a suction cup structure provided at its output end, and its working distance is to re-absorb the felt paper through the suction cup mechanism after extending through the telescopic cylinder and move the felt paper until it is placed above the metal tube layer. Moreover, in the above structure, the placement telescopic member can be moved to the top of the tray, and the minimum spacing between the placement telescopic member and the felt paper absorber 23 in the horizontal direction is greater than 0, ensuring that the placement telescopic member will not collide with the felt paper absorber 23. For this reason, the absorption position of the placement telescopic member 63 is arranged relative to the end of the felt paper close to the conveying mechanism 1 and away from the side of the conveying mechanism 1. That is to say, the absorption position of the placement telescopic member 63 and the felt paper is farther away from the conveying mechanism 1 than the absorption position of the felt paper absorber 23 and the felt paper.

[0045] Finally, the above structure can be used to achieve that, on the basis of the existing structure, by adding a rangefinder to sense the felt paper 7, it can be detected in time when the felt paper 7 falls during the movement process, and by setting a follow-up resetter 5, the felt paper 7 can be reset, so there is no need to manually handle the felt paper 7, and there is no need to shut down the entire machine. In addition, the felt paper 7 can be automatically re-placed by means of the compensation placer 6.

[0046] As a preferred embodiment, in order to properly lay out the felt paper 7, the compensating placement device 6 can be started after the telescopic member 55 and the follower suction cup 56 are in the working state and reach the reset position. Since the parameter for the telescopic member 55, that is, the follower suction cup 56 to stop working depends on that after reaching the minimum horizontal distance with the lifting mechanism 3, if the reading of the midway distance meter changes, the telescopic member 55 needs to return immediately, so it cannot continue to move to the position where the minimum horizontal distance with the lifting mechanism 3 is reached. For this reason, it cannot stop normally, which ensures that during the return process of the felt paper, it can be sucked and pulled back to the initial position by the follower suction cup 56. At this time, the placement of the telescopic member 63 requires the extension and absorption of the felt paper 7, and then the moving rail beam 62 moves toward the lifting mechanism 3 until the felt paper 7 is placed in the specified position and reset. Since during this process, the telescopic member 55 can reach the minimum horizontal distance with the lifting mechanism 3, the follower suction cup 56 will be out of the negative pressure state and avoid affecting the normal placement of the felt paper.

[0047] In order to quickly rearrange the felt paper 7, the speed at which the telescopic member 55 moves away from the lifting mechanism 3 is greater than the moving speed of the reciprocating arranging mechanism 2. That is to say, the above process needs to be completed as much as possible before the reciprocating arranging mechanism 2 places the metal can to avoid causing equipment shutdown.
