Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of logistics conveying line, more specifically, relate to a blocking and turning device. BACKGROUND

[0002] In industrial production and warehousing logistics, the power roller line as the core equipment of material transmission, through the synchronous rotation of multiple parallel rollers, realizes the continuous and efficient conveying of materials. Its simple structure and reliable operation make it widely used in the handling of materials such as cartons and pallets. However, with the increasing demand for industrial automation and the complexity of process flow, the existing power roller line gradually exposes the following technical bottlenecks in actual application:

[0003] 1. Insufficient material direction adjustment capability

[0004] The current power roller line mainly relies on the one-way rotation of the roller to realize the straight-line transmission of the material, but when facing the transportation demand of adjusting the direction of the material such as labeling and boxing, it lacks active control capability. For example, when the initial placement angle of the carton deviates from the transmission direction, or the material needs to be rotated horizontally by 0°~±90°, 0°~180°, the existing roller line cannot adjust the angle through its own structure and needs to rely on manual intervention, resulting in reduced efficiency and increased cost.

[0005] 2. Lack of dynamic blocking and flow coordination mechanism

[0006] In the multi-station collaborative operation scene, if the current station needs to temporarily block the upstream material flow due to incomplete processing, the traditional roller line usually uses fixed baffles or independent sensors for passive interception, which has the problems of response lag and poor compatibility. It cannot dynamically adjust the blocking position and release timing according to the real-time working condition, which easily leads to material accumulation or imbalance between stations, affecting the overall line efficiency.

[0007] 3. Control system complexity and cost surge

[0008] On some roller lines, blocking pieces are added for blocking. To adapt to roller lines of different widths, multiple blocking pieces need to be densely arranged along the width direction, and each blocking piece needs to be configured with an independent cylinder, a supporting solenoid valve, a sensor, and a control circuit. When the roller line is wide or needs to integrate multiple sets of blocking pieces, the number of cylinders, air path pipes, and I / O ports of PLC (Programmable Logic Controller) increases linearly, resulting in a significant increase in hardware cost. In addition, the cooperative control of multiple cylinders requires complex program logic support, which not only increases the development and debugging difficulty, but also may be forced to use a multi-PLC cascade scheme due to insufficient I / O resources, further aggravating system redundancy and compatibility risks.

[0009] It is worth mentioning that the intensive deployment of a large number of cylinders and auxiliary elements also significantly increases the equipment failure rate, and problems such as air leakage of air path joints, electromagnetic valve jamming, and aging of cylinder seals frequently occur, forcing maintenance personnel to frequently overhaul and replace parts, causing the production line downtime to be extended. At the same time, multiple cylinder independent speed regulation needs to manually adjust the throttle valve one by one, which is difficult to ensure the consistency of the action timing, and is easy to cause material turning angle deviation or transmission jamming, affecting the overall production line stability.

[0010] Secondly, the instantaneous gas consumption increases dramatically when multiple cylinders act synchronously, and if the air compressor power is insufficient, it will lead to air pressure fluctuation or even system paralysis; if the air compressor power is blindly increased to ensure the stability of the gas supply, it will cause energy waste and noise pollution.

[0039] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention by way of example, but should not be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments.

[0040] To better understand this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further illustrate the present utility model:

[0041] See Figure 1As shown in the utility model embodiment, the blocking and turning device is installed below, and the blocking and turning device can select the number of additional devices according to actual production needs, and when a plurality of blocking and turning devices are arranged, the plurality of blocking and turning devices are arranged along the length direction of the cylinder line 9.

[0042] In the embodiment, the blocking and turning device comprises a mounting base 1, an executing mechanism 2, a linkage driving mechanism 3 and a reset mechanism 4.

[0043] Referring to Figure 2 and Figure 4 As shown in the utility model embodiment, the executing mechanism 2 comprises a plurality of lifting blocking units 21, the plurality of lifting blocking units 21 are sequentially arranged along the length direction of the mounting base 1, and the executing mechanism 2 has a blocking station for protruding the plurality of lifting blocking units 21 above a conveying surface and a release station for retracting the plurality of lifting blocking units 21 below the conveying surface.

[0044] In the embodiment, the initial state of the executing mechanism 2 is in the blocking station, and the upper ends of the plurality of lifting blocking units 21 protrude above the conveying surface to block the movement of the material on the cylinder line 9, and when the release is needed, the plurality of lifting blocking units 21 are sequentially lowered to retract below the conveying surface, thereby allowing the material to advance on the cylinder line 9.

[0045] Referring to Figure 2 The linkage driving mechanism 3 comprises at least one linear motion assembly 31, and the linear motion assembly 31 is used for sequentially lowering the plurality of lifting blocking units 21 according to a preset time sequence to make the executing mechanism 2 in the release station. In the embodiment, the linkage driving mechanism 3 comprises two linear motion assemblies 31, and the two linear motion assemblies 31 are arranged on the two sides of the executing mechanism 2 respectively, one linear motion assembly 31 is used for controlling the plurality of lifting blocking units 21 to sequentially lower from left to right to the release station, and the other linear motion assembly 31 is used for controlling the plurality of lifting blocking units 21 to sequentially lower from right to left to the release station, and the two linear motion assemblies 31 are independently controlled, and in actual application, which linear motion assembly 31 is selected according to the required rotation direction (counterclockwise or clockwise) of the material, thereby making the material rotate towards the required direction.

[0046] In the embodiment, the reset mechanism 4 is configured to trigger the plurality of lifting blocking units 21 to rise to reset to the blocking station under the driving of the linkage driving mechanism 3.

[0047] Referring to Figure 7 and Figure 8As shown, the blocking and turning device further comprises a plurality of hook assemblies 5, the plurality of hook assemblies 5 are installed on the mounting base 1, the plurality of hook assemblies 5 and the plurality of lifting blocking units 21 are one-to-one correspondingly arranged, when the actuator 2 is in the release station, each lifting blocking unit 21 is clamped with the hook assembly 5 arranged correspondingly, the hook assembly 5 is in contact with the reset mechanism 4, and the hook assembly 5 can be driven by the reset mechanism 4 to release the position locking of the lifting blocking unit 21.

[0048] As shown in Figures 3-4 As shown, the lifting blocking unit 21 comprises a blocking piece 211 arranged along the Z-axis direction, a first follow-up assembly 212, a first clamping block 213 and an elastic element 214 arranged along the Z-axis direction.

[0049] Specifically, the blocking piece 211 is used for physically intercepting or releasing the material (such as a carton, a packaging box and the like) located on the drum line 9 in the Z-axis direction (vertical direction), the blocking piece 211 can vertically move up and down to change the blocking state, for example, intercepting when rising and releasing when falling.

[0050] The first follow-up assembly 212 is installed on the blocking piece 211, and at least a part of the first follow-up assembly 212 is located on the running path of the linear motion assembly 31, when the linear motion assembly 31 runs and contacts the first follow-up assembly 212, as the linear motion assembly 31 continues to run along the running direction, the linear motion assembly 31 exerts a force on the first follow-up assembly 212 to drive the first follow-up assembly 212 to move downward along the Z-axis direction, the blocking piece 211 connected with the first follow-up assembly 212 moves downward along the Z-axis direction, and the horizontal motion of the linear motion assembly 31 is converted into the vertical motion of the blocking piece 211, so that the blocking piece 211 can be switched from the blocking station to the release station.

[0051] The first clamping block 213 is installed at the lower end of the blocking piece 211, the upper end of the elastic element 214 abuts against the first clamping block 213, and the lower end of the elastic element 214 abuts against the mounting base 1.

[0052] Specifically, the elastic element 214 is a kind of mechanical component capable of storing and releasing energy under the action of force or deformation, and the elastic element 214 includes but is not limited to a metal spring and a rubber elastic body. In the embodiment, the elastic element 214 is preferably a metal spring.

[0053] As shown in Figure 2 , Figure 3 and Figure 6 As shown, the linear motion assembly 31 comprises a guide rod 311 and a first sliding block 312 movably installed on the guide rod 311.

[0054] Specifically, the guide rod 311 provides a movement path constraint for the first slider 312, ensuring that the first slider 312 can move linearly along the length direction (X-axis direction) of the guide rod 311. The first slider 312 is provided with a first guide inclined surface 3121 at the lower end, which is in abutment with the first follower assembly 212 when the first slider 312 moves along the length direction of the guide rod 311 from left to right or from right to left.

[0055] When the first slider 312 moves along the X-axis to the right or to the left, the first guide inclined surface 3121 is in contact with the first follower assembly 212, and the first guide inclined surface 3121 pushes the first follower assembly 212 to move downward along the Z-axis. This design can convert the horizontal movement (X-axis) of the first slider 312 into the vertical movement (Z-axis) of the first follower assembly 212, so as to drive the first follower assembly 212 to move downward in the Z-axis direction, thereby causing the blocking piece 211 connected with the first follower assembly 212 to descend below the conveying surface.

[0056] In this embodiment, the first follower assembly 212 is a cam follower.

[0057] The reset mechanism 4 includes a swing assembly 41 and a rotating assembly 42, which are in contact. When the first slider 312 moves from right to left to a predetermined position, the swing assembly 41 is triggered to swing to drive the rotating assembly 42 to rotate by a predetermined angle, and the rotating assembly 42 drives the hook assembly 5 to act, so as to release the position locking of the lifting blocking unit 21.

[0058] Specifically, when the first slider 312 moves to a predetermined position, the first slider 312 collides or slides with the swing assembly 41, so that the swing assembly 41 is triggered to swing, and then drives the rotating assembly 42 to act, and the rotating assembly 42 drives the hook assembly 5 to act, so as to release the position locking of the lifting blocking unit 21.

[0059] Referring to Figure 3 As shown, the swing assembly 41 includes a first swing rod 411, a second swing rod 412, and a cross rod 413. The lower end of the first swing rod 411 is hinged to the mounting base 1, the first swing rod 411 is hinged to the cross rod 413, the upper end of the first swing rod 411 is provided with a second follower assembly 414 for cooperating with the linear motion assembly 31, and the first swing rod 411 is connected to the mounting base 1 through a first tension spring 415. The lower end of the second swing rod 412 is hinged to the mounting base 1, the upper end of the second swing rod 412 is hinged to the cross rod 413, and the second swing rod 412 is connected to the mounting base 1 through a second tension spring 416.

[0060] Referring to Figures 7-8As shown, the hook assembly 5 comprises a fixed seat 51, a second clamping block 52 and a limiting rod 53, the lower end of the second clamping block 52 is connected with the fixed seat 51 through a rotating shaft, one end of the limiting rod 53 is fixedly installed on the fixed seat 51, the other end of the limiting rod 53 is arranged in a hole of the second clamping block 52, and the limiting rod 53 and the hole are in clearance fit, and the upper end of the second clamping block 52 is provided with a second guide inclined surface 521.

[0061] The rotating assembly 42 comprises a third follower assembly 421, a fixed block 422 and a driving rod 423 installed on the fixed block 422, the third follower assembly 421 is fixedly connected with the fixed block 422, the fixed block 422 is movably installed on the fixed rod of the installation base 1, the fixed block 422 is provided with an avoiding groove 4221, the driving rod 423 is arranged in the avoiding groove 4221, and at least a part of the upper end of the second clamping block 52 is arranged in the avoiding groove 4221, and the driving rod 423 abuts against the second guide inclined surface 521.

[0062] In the embodiment, the second follower assembly 414 and the third follower assembly 421 are both cam followers.

[0063] Referring to Figure 3 As shown, the cross rod 413 is horizontally placed, and the plurality of third follower assemblies 421 abut against the upper end surface of the cross rod 413, when the first swing rod 411 is hit by the first sliding block 312 to rotate counterclockwise, the second swing rod 412 swings, and at the same time, the cross rod 413 with two ends hinged on the first swing rod 411 and the second swing rod 412 is lifted to lift the plurality of third follower assemblies 421, so as to drive the fixed block 422 to rotate by a certain angle around the fixed rod, so that the driving rod 423 at the lower end of the fixed block 422 presses the second clamping block 52 backward, and the second clamping block 52 rotates around the rotating shaft to release the position locking of the lifting blocking unit 21.

[0064] It is worth mentioning that only a small part of the first clamping block 213 and the second clamping block 52 are clamped in the embodiment, the limiting rod 53 and the hole are in clearance fit, that is, the diameter of the limiting rod 53 is smaller than the hole diameter of the hole, and the design can on the one hand allow the second clamping block 52 to rotate by a certain angle, so that the first clamping block 213 can be lifted in the Z-axis direction under the action of the elastic element 214, so that the blocking piece 211 rises to the blocking position; on the other hand, it prevents the second clamping block 52 from rotating too large, and ensures that the second clamping block 52 can return to the vertical placement state under the action of its own gravity without external force.

[0065] Referring to Figure 8As shown, the rotating assembly 42 comprises a third follower assembly 421, a fixed block 422 and a driving rod 423 mounted on the fixed block 422, the third follower assembly 421 and the fixed block 422 are fixedly connected, the fixed block 422 is movably mounted on the fixed rod of the mounting base 1, the fixed block 422 is provided with an avoiding slot 4221, the driving rod 423 is arranged in the avoiding slot 4221, and at least a part of the upper end of the second clamping block 52 is arranged in the avoiding slot 4221, and the driving rod 423 abuts on the second guide inclined surface 521.

[0066] Preferably, the lower end of the first clamping block 213 is provided with a third guide inclined surface 2131, and the third guide inclined surface 2131 corresponds to the second guide inclined surface 521.

[0067] Referring to Figure 2 and Figure 4 As shown, the blocking piece 211 comprises a second sliding block 2111 and a blocking column 2112, the mounting base 1 is provided with a sliding rail 6, the second sliding block 2111 is connected with the sliding rail 6 in a matched mode, and the blocking column 2112 is mounted on the second sliding block 2111, so that the movement stability of the blocking piece 211 can be ensured.

[0068] In the embodiment, the outer wall of the blocking column 2112 is sleeved with a pipe sleeve 7, and the pipe sleeve 7 and the blocking column 2112 are connected through a deep groove ball bearing 8, so that the pipe sleeve 7 can rotate relative to the blocking column 2112.

[0069] When the material moves on the cylinder line 9 along with the cylinder, the bottom part is in contact with the cylinder to generate a friction force, the force serves as an initial power to drive the material to move, the pipe sleeve 7 rotates through the deep groove ball bearing 8 with low resistance, so that the pipe sleeve 7 can avoid causing a pressure mark on the surface of the material and reduce the breakage rate of the material.

[0070] When the material is in contact with the pipe sleeve 7, under the combined action of the cylinder friction force and the self-rotation of the pipe sleeve 7, the material can be rotated by a predetermined angle, and then the material can be quickly rotated by multiple angles.

[0071] In order to further explain and illustrate, the utility model embodiment further provides the working principle of the blocking and turning device, and the working principle is as follows:

[0072] Step 1: initial state (blocking position)

[0073] The actuator 2 is in the initial blocking position, the blocking piece 211 of all the lifting blocking units 21 is kept in the upper top state under the action of the elastic element 214 (metal spring), the top end of the blocking piece 211 protrudes from the transmission surface of the cylinder line 9, physical interception is formed on the material (such as a carton and a packaging box), and the material is prevented from moving along the cylinder line 9.

[0074] Step 2: trigger release signal and direction selection

[0075] According to the production requirements (such as the material needs to be flipped clockwise or counterclockwise), select the corresponding linear motion assembly 31 (left or right), for example: if the material needs to be flipped counterclockwise, use the left linear motion assembly 31; if it needs to be flipped clockwise, use the right linear motion assembly 31.

[0076] Start the linear motion assembly 31 in the selected direction, and the first slider 312 starts to move from left to right or from right to left along the length direction (X-axis direction) of the guide rod 311.

[0077] Step 3: The linear motion assembly 31 drives the plurality of lifting blocking units 21 to descend in turn

[0078] When the first slider 312 moves, the first guide slope 3121 at the lower part thereof contacts the first follower assembly 212 of the lifting blocking unit 21, and as the slider continues to move, the slope pushes the first follower assembly 212 to move downward along the Z-axis, thereby driving the blocking piece 211 connected thereto to descend synchronously.

[0079] The plurality of lifting blocking units 21 descend in turn (for example, from left to right) according to the preset timing, so that the blocking pieces 211 are retracted one by one below the conveying surface. When the material contacts the pipe sleeve 7 of the blocking column 2112, the material is flipped by a certain angle in the preset direction (clockwise or counterclockwise) under the combined action of the friction force of the drum line 9 and the rotation of the pipe sleeve 7, thereby completing the turning requirement.

[0080] Specifically, when contacting the material, the pipe sleeve 7 rotates with low resistance through the deep groove ball bearing 8, which can avoid causing indentations or damage to the surface of the material.

[0081] When the first clamping block 213 of each lifting blocking unit 21 descends to the predetermined position, it is partially clamped with the second clamping block 52 of the corresponding hook assembly 5, thereby ensuring that the actuator 2 is in the release position.

[0082] Step 4: The hook assembly 5 releases the position locking

[0083] When the material passes smoothly, the first slider 312 moves back and hits the second follower assembly 414 at the upper end of the first swing lever 411, causing the first swing lever 411 to swing counterclockwise around the hinge point.

[0084] The first swing lever 411 drives the second swing lever 412 to swing synchronously through the cross bar 413, which lifts and lifts the plurality of third follower assemblies 421, thereby driving the fixed block 422 to rotate around the fixed rod;

[0085] Since the driving rod 423 on the fixed block 422 abuts against the second guide slope 521 of the second clamping block 52, when the fixed block 422 rotates, it forces the second clamping block 52 to rotate around the rotating shaft, so that the second clamping block 52 and the first clamping block 213 are disengaged from the clamped state, thereby releasing the position locking of the lifting blocking unit 21.

[0086] Step 5: the reset mechanism 4 is started (the blocking station is restored)

[0087] The elastic element 214 (metal spring) releases the stored elastic potential energy, pushes the first clamping block 213, the first follower assembly 212 and the blocking piece 211 to move upward along the Z axis, so that the blocking piece 211 protrudes above the conveying surface again;

[0088] When the linear motion assembly 31 stops driving, the first tension spring 415 and the second tension spring 416 pull the first swing rod 411 and the second swing rod 412 back to the initial position, the cross rod 413 descends, and the third follower assembly 421 and the fixed block 422 are reset, and at the same time, the second clamping block 52 returns to the vertical state under the action of its own gravity.

[0089] The blocking steering device has the following technical effects:

[0090] Only two horizontally arranged air cylinders are needed to drive the first sliding block 312 to move, a plurality of lifting blocking units 21 are driven to move downward in the vertical direction in turn through the linkage of the first sliding block 312, the horizontal movement of the air cylinder driving the first sliding block 312 is converted into the vertical lifting movement of the plurality of lifting blocking units 21, and "one-to-many" driving is realized. No matter how the width of the drum line 9 increases or the number of the blocking pieces 211 increases, new air cylinders are not needed, so that the production cost is reduced, and air cylinders, solenoid valves and other components do not need to be additionally purchased. Secondly, the PLC control logic only needs to manage the actions of two air cylinders, and the program does not need to be modified due to the change in the number of the blocking pieces 211. Moreover, the input and output points of the PLC are constant, and the cost of modifying and upgrading the production line can be saved. When the production line needs to be widened or adjusted, only the lifting blocking units 21 and other components matched therewith need to be added to the mechanical structure, and the control circuit does not need to be redesigned or the program does not need to be updated, so that the reform period is significantly shortened.

[0091] The lifting actions of the plurality of blocking pieces 211 are only driven in cooperation with two air cylinders and two first sliding blocks 312, the control circuit is simple and standardized, even if the number of the blocking pieces 211 increases, the electrical wiring does not need to be changed, only the mechanical expansion is needed, so that subsequent production line maintenance is simple, and the time consumption for replacing the air cylinders is less.

[0092] When the material needs to be continuously turned in the same direction (clockwise or counterclockwise), only one side air cylinder needs to be operated to realize the continuous turning of the material, and the air cylinder on the other side remains stationary, so that the air consumption is reduced. Compared with the simultaneous action of multiple air cylinders, the single air cylinder operation can significantly reduce the amount of compressed air, which not only reduces the energy cost, but also makes the air cylinder speed regulation simple and fast.
