Description

Technical Field

[0001] The utility model relates to the technical field of automation mechanisms, in particular to a material pushing mechanism with a card material detection function. Background Art

[0002] The conveying mechanism of the prior art usually relies on the friction between the conveyor belt and the material to drive the material into the next process. During the material conveying process, the material and the conveyor belt are prone to relative sliding due to insufficient friction. The control of the material position can usually only be achieved by relying on the baffle plate, and the position of the baffle plate needs to be readjusted each time the material of different specifications is replaced, which makes the material operation efficiency relatively low. Especially when the material is at the two end positions of the conveyor belt, only a part of the material is in contact with the conveyor belt, so that the friction between the material and the conveyor belt is small, which easily causes the conveyor belt to fail to drive the material forward, that is, the material is easily stuck at the two ends of the conveyor belt. When the material is stuck, the system cannot timely know that the material is in an abnormal state of being stuck. It is necessary to wait until the sensor in the next process still does not receive the material within the preset time before the system will send an alarm signal of material being stuck. Therefore, the prior art cannot timely determine whether the material is in an abnormal state of being stuck, which has a great impact on the continuous operation of the material. Moreover, due to the width restrictions of the drive motor, the synchronous wheel and the conveyor belt, the existing conveyor belt cannot transport materials with extremely small width. Utility Model Content

[0003] The utility model aims to provide a material pushing mechanism with a material jam detection function, which mainly solves the technical problem of how to reliably convey materials and timely know whether the materials are jammed in a low-cost manner during the conveying process.

[0004] To achieve this purpose, the utility model adopts the following technical solutions:

[0005] A material pushing mechanism with a card material detection function comprises a first driving module, a second driving module and a material pushing assembly which are connected in sequence;

[0006] The first driving module is used to drive the second driving module and the material pushing assembly to move together in a first horizontal direction, and the second driving module is used to drive the material pushing assembly to rise or fall in a vertical direction;

[0007] The pusher assembly includes a connected mounting base, a push block, a sensor and a first elastic member. The mounting base is connected to the second driving module. The push block is slidably connected to the mounting base along the first direction. The first elastic member applies an elastic force to the push block along the positive direction of the first direction. The sensor is used to sense whether the sliding distance of the push block relative to the mounting base on a straight line in the first direction exceeds a preset range.

[0008] In one of the technical solutions, the pusher assembly further includes a second elastic member, and the second elastic member applies an elastic force to the push block in a direction opposite to the first direction.

[0009] In one of the technical solutions, the sensor is used to emit detection light, and a notch is provided on the push block. When the distance that the push block slides relative to the mounting seat on a straight line in the first direction does not exceed a preset range, the notch is located on the emission path of the detection light; when the distance that the push block slides relative to the mounting seat on a straight line in the first direction exceeds a preset range, the notch is not on the emission path of the detection light.

[0010] In one technical solution, both the first elastic member and the second elastic member are compression springs.

[0011] In one of the technical solutions, the first driving module includes a base, a motor, a driving wheel, a driven wheel, a transmission belt and a first guide rail;

[0012] The motor and the first guide rail are both fixed on the base, the length direction of the first guide rail is parallel to the first direction, the driving wheel is connected to the output shaft of the motor, the driven wheel is rotatably connected to the base, the transmission belt is respectively wound around the driving wheel and the driven wheel, and the second driving module is fixed on the transmission belt and slidably connected to the first guide rail along the first direction.

[0013] In one of the technical solutions, the first driving module further includes a tensioning wheel, which is rotatably connected to the base and abuts against the transmission belt.

[0014] In one of the technical solutions, the first driving module also includes a drag chain, one end of which is fixed to the base, and the other end of the drag chain is connected to the second driving module. Wire components are extended from the sensor and the second driving module, and the wire components are cables or air pipes. Part of the wire components is accommodated inside the drag chain.

[0015] In one of the technical solutions, the second driving module includes a slide, a cylinder, a lifting block and a second guide rail;

[0016] The slide seat is slidably connected to the first guide rail along the first direction, the cylinder and the second guide rail are both fixed on the slide seat, the length direction of the second guide rail is parallel to the vertical direction, the lifting block is slidably connected to the second guide rail in the vertical direction, the cylinder is connected to the lifting block and is used to drive the lifting block to slide reciprocatingly in the vertical direction, and the lifting block is fixedly connected to the mounting seat.

[0017] Compared with the prior art, the material pushing mechanism with the function of collecting card material detection provided by the utility model has at least the following beneficial effects:

[0018] When the present scheme is working, the second driving module drives the pushing assembly to descend, so that the pushing block in the pushing assembly descends to the adjacent position of the material, and then the first driving module drives the second driving module and the pushing assembly to move along the first direction together, so that the material is conveyed to the designated position along the first direction under the push of the pushing block. When the material is in place, the second driving module drives the pushing assembly to rise, and at the same time, the first driving module drives the second driving module and the pushing assembly to make a reset movement in the opposite direction of the first direction. The push block in the risen pushing assembly will not collide with the next material to be conveyed when making a reset movement in the opposite direction of the first direction. Finally, the second driving module drives the pushing assembly to descend again, so that the push block in the pushing assembly descends to the adjacent position of the next material to be conveyed. The above cycle is repeated in sequence, and the materials can be automatically conveyed to the designated position one by one. When the material is in a jamming state, the push block will be subjected to the reaction force of the material and will drive the first elastic member to deform and will slide in a straight line in the first direction relative to the mounting seat. When the sensor senses that the sliding distance of the push block relative to the mounting seat exceeds the preset range, it can be promptly determined that the material is in a jamming state. When the material jamming problem is solved, the push block in the push assembly is automatically reset by the elastic force of the first elastic member, so that the push assembly has the function of automatically detecting jams again.

[0019] In summary, this technical solution can not only reliably and stably realize the basic function of automatically pushing materials, but also promptly detect whether the material is in a stuck state. It is relatively simple in structure, so its implementation cost is low. This solution can also be compatible with the transmission needs of materials with extremely small widths.

In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Please also read Figures 1 to 6 This embodiment provides a material pushing mechanism with a card material detection function, which includes a first driving module 1, a second driving module 2 and a material pushing assembly 3 connected in sequence.

[0037] The first driving module 1 is used to drive the second driving module 2 and the material pushing assembly 3 to move along the horizontal first direction (i.e., the Y axis), the second driving module 2 is used to drive the material pushing assembly 3 to rise or fall along the vertical direction, and the material pushing assembly 3 is used to push the material to a specified position when moving along the Y axis. The first driving module 1 and the second driving module 2 can select one of the screw module, synchronous belt module, gear rack structure, linear motor or cylinder module according to the moving accuracy.

[0038] Among them, the pushing assembly 3 specifically includes a connected mounting seat 31, a pushing block 32, a sensor 33 and a first elastic member 34, the sensor 33 is fixed on the mounting seat 31, the mounting seat 31 is connected to the above-mentioned second driving module 2, the pushing block 32 is slidably connected with the mounting seat 31 along the Y-axis, the first elastic member 34 is preferably a compression spring, one end of the first elastic member 34 abuts on the mounting seat 31, and the other end of the first elastic member 34 abuts on the pushing block 32 and applies an elastic force to the pushing block 32 along the positive direction of the Y-axis, and the sensor 33 is used to sense whether the sliding distance of the push block 32 relative to the mounting seat 31 on the straight line of the Y-axis exceeds a preset range.

[0039] Specifically, during operation, the second driving module 2 drives the pushing assembly 3 to descend, so that the pushing block 32 in the pushing assembly 3 descends to the adjacent position of the material, and then the first driving module 1 drives the second driving module 2 and the pushing assembly 3 to move along the positive direction of the Y-axis, so that the material is conveyed to the designated position along the positive direction of the Y-axis under the push of the pushing block 32. When the material is in place, the second driving module 2 drives the pushing assembly 3 to rise, and at the same time, the first driving module 1 drives the second driving module 2 and the pushing assembly 3 to perform a reset movement along the opposite direction of the Y-axis. The pushing block 32 in the risen pushing assembly 3 will not collide with the next material to be conveyed when performing a reset movement along the opposite direction of the Y-axis. Finally, the second driving module 2 drives the pushing assembly 3 to descend again, so that the pushing block 32 in the pushing assembly 3 descends to the adjacent position of the next material to be conveyed. The above cycle is repeated in sequence, and the materials can be automatically conveyed to the designated positions one by one. When the material is in a stuck state, the push block 32 is subjected to the reaction force of the material and will drive the first elastic member 34 to deform in the opposite direction of the Y-axis and will slide on the straight line of the Y-axis relative to the mounting seat 31. When the sensor 33 senses that the sliding distance of the push block 32 relative to the mounting seat 31 exceeds the preset range, it can be promptly determined that the material is in a stuck state. Otherwise, the material is accurately pushed to the specified position by the push block 32. When the material jam problem is solved, the push block 32 in the push assembly 3 is automatically reset by the elastic force of the first elastic member 34, so that the push assembly 3 has the function of automatically detecting jams again.

[0040] In this embodiment, the pushing assembly 3 also includes a second elastic member 35, which is preferably also a compression spring. One end of the second elastic member 35 abuts against the mounting seat 31, and the other end of the second elastic member 35 abuts against the pushing block 32 and applies an elastic force to the pushing block 32 in the opposite direction of the Y-axis. The pushing block 32 is in an initial position under the elastic force of the first elastic member 34 and the elastic force of the second elastic member 35 at the same time. By setting the second elastic member 35, the pushing block 32 in the pushing assembly 3 can slide relative to the mounting seat 31 in the positive direction of the Y-axis when pushing the material in the opposite direction of the Y-axis, that is, the pushing assembly 3 not only has the function of detecting material jams when pushing the material in the positive direction of the Y-axis, but also has the function of detecting material jams when pushing the material in the opposite direction of the Y-axis.

[0041] In this embodiment, the sensor 33 can emit detection light, and the push block 32 is provided with a notch 321. When the sliding distance of the push block 32 relative to the mounting seat 31 on the straight line along the Y axis does not exceed the preset range, the notch 321 is located on the emission path of the detection light. When the sliding distance of the push block 32 relative to the mounting seat 31 on the straight line along the Y axis exceeds the preset range, the notch 321 is not on the emission path of the detection light. The maximum value of the above-mentioned preset range can be understood as half of the width of the notch 321.

[0042] In this embodiment, the first driving module 1 specifically includes a base 11, a motor 12, a driving wheel 13, a driven wheel 14, a transmission belt 15, a first guide rail 16 and at least one tensioning wheel 17, wherein the motor 12 and the first guide rail 16 are both fixed on the base 11, the length direction of the first guide rail 16 is parallel to the Y-axis, the driving wheel 13 is fixed on the output shaft of the motor 12, there are at least two driven wheels 14, and the two driven wheels 14 are both rotatably connected to the base 11, the transmission belt 15 is respectively wound around the driving wheel 13 and each driven wheel 14, and the above-mentioned second driving module 2 is clamped on the transmission belt 15 and is slidably connected to the first guide rail 16 on the Y-axis through a slider. During operation, the motor 12 drives the driving wheel 13 to rotate, and the driving wheel 13 drives the transmission belt 15 to transmit, thereby driving the second driving module 2 and the pushing assembly 3 to move along the Y-axis, and the tensioning wheel 17 is rotatably connected to the base 11 and abuts against the transmission belt 15 to tension the transmission belt 15 so that the transmission belt 15 will not slip with the driving wheel 13 during transmission, thereby ensuring the reliability and stability of the driving wheel 13 driving the transmission belt 15 to move.

[0043] In this embodiment, the first drive module 1 also includes a drag chain 18, one end of the drag chain 18 is fixed on the base 11, and the other end of the drag chain 18 is connected to the second drive module 2. The above-mentioned sensor 33 and the second drive module 2 are both extended with wire components (not shown in the figure). The wire component can be a conductive cable or a ventilation air pipe. Part of the wire component is accommodated inside the drag chain 18, so that when the second drive module 2 and the pushing assembly 3 move a long stroke along the Y-axis together, the wire component will not collide with other external components, so as to avoid the wire component from being torn off, thereby improving the working stability of the pushing mechanism.

[0044] In this embodiment, the second driving module 2 specifically includes a slide 21, a cylinder 22, a lifting block 23 and a second guide rail 24, wherein the slide 21 is slidably connected to the above-mentioned first guide rail 16 along the Y-axis through a slider, the cylinder 22 and the second guide rail 24 are both fixed on the slide 21, the length direction of the second guide rail 24 is parallel to the vertical direction, the lifting block 23 is slidably connected to the second guide rail 24 in the vertical direction through the slider, the output end of the cylinder 22 is connected to the lifting block 23 and is used to drive the lifting block 23 to slide back and forth in the vertical direction, the lifting block 23 is fixedly connected to the mounting seat 31 in the above-mentioned pushing assembly 3, so that when the cylinder 22 drives the lifting block 23 to rise or fall in the vertical direction, the pushing assembly 3 can rise or fall synchronously with the lifting block 23.

[0045] To sum up, this technical solution can not only reliably and stably realize the basic function of automatically pushing materials, but also detect whether the material is in a stuck state in a timely manner. It has a relatively simple structure, so its implementation cost is low. This solution can also be compatible with the transmission needs of materials with extremely small widths.

[0046] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
