Description

Technical Field

[0001] The present invention relates to the field of chemical fiber production and manufacturing, and particularly to a silk cart conveying device. Background Art

[0002] A silk cart is a transportation device used for loading a large number of silk cakes for handling the silk cakes. However, a fully loaded silk cart is heavy, and it is easy to damage the rollers of the silk cart and the floor of the workshop during use. To solve the above problems, the industry has introduced a silk cart conveying device, as Figure 1 shown. It mainly includes two guide rails 1 laid on the ground and arranged in parallel. Along the length direction of the upper surface of the guide rail 1, a plurality of support wheels 2 for supporting the bottom of the silk cart 37 are arranged, so that the rollers 29 of the silk cart 37 can be lifted off the ground. In this way, during the long-distance transmission of the silk cart 37, it can not only be more labor-saving, but also effectively reduce the damage to the rollers 29 and the workshop floor.

[0003] However, for the above-mentioned silk cart conveying device, due to the large height difference between the support wheels 2 on the guide rail 1 and the ground, it is necessary to use a crane or a forklift to transfer the silk cart 37 from the ground to above the support wheels 2. This is not only cumbersome to operate, but also has a large potential safety hazard, so it still needs to be improved. Summary of the Invention

[0004] Aiming at the shortcomings of the prior art, the present invention provides a silk cart conveying device. Through a driving mechanism and a crawler conveyor, the silk cart on the ground can be transferred to the support wheels of the guide rail, thereby improving the operation efficiency and convenience and ensuring the operation safety.

[0005] To solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A silk cart conveying device includes a guide rail laid on the ground. Along the length direction of the upper surface of the guide rail, a plurality of support wheels are rotatably arranged. At the front end of the guide rail, a base buried in the ground is provided. Above the base, a support member corresponding to the guide rail one by one is provided. A crawler conveyor is arranged on the support member. A driving mechanism for driving the crawler conveyor to lift and lower is arranged in the base and is connected to the support member; a balance detection block is arranged between the crawler conveyor and the guide rail. The balance detection block is matched with a detection mechanism for judging whether the balance detection block is squeezed by the silk cart. An elastic reset mechanism for driving the balance detection block to reset is arranged on the detection mechanism. On the side of the balance detection block close to the crawler conveyor, a detection module for detecting the change of the surface friction coefficient of the conveyor belt of the crawler conveyor is arranged;

[0007] When the silk reeling machine presses against the balance detection block and is determined to be in a balanced state, the driving mechanism drives the crawler conveyor to rise to abut against the bottom of the silk reeling machine and lift the silk reeling machine; when the silk reeling machine is lifted to a height where it is separated from the balance detection block, the elastic reset mechanism drives the balance detection block to reset, so that the detection module closely adheres to one end of the crawler conveyor close to the guide rail, and then the crawler conveyor operates to transfer the silk reeling machine to the support wheel, and the detection module detects the change in the friction coefficient of the conveyor belt.

[0008] With the above solution, through the driving mechanism and the crawler conveyor, the silk reeling machine on the ground can be easily transferred to the support wheel of the guide rail, thereby effectively improving the operation efficiency and convenience, and ensuring the safety of the silk reeling machine handling. The cooperation between the balance detection block and the detection mechanism can effectively determine the balance state of the silk reeling machine in the horizontal direction before it is lifted, so as to prevent the silk reeling machine from having a large position deflection during the transfer process through the crawler conveyor, thereby improving the accuracy of the silk reeling machine transfer. The elastic reset mechanism can not only drive the balance detection block to reset after the silk reeling machine is lifted to wait for the next round of balance detection, but also drive the detection module on the balance detection block to closely adhere to the conveyor belt of the crawler conveyor to obtain the friction coefficient of the conveyor belt, so as to facilitate the staff to replace the conveyor belt in time according to the attenuation of the friction coefficient, and then ensure the conveying efficiency and balance of the crawler conveyor, making the silk reeling machine more stable during the transfer to the support wheel and less likely to have a deflection in the horizontal direction.

[0009] Preferably, the detection mechanism includes a pressing rod arranged on the side of the balance detection block away from the crawler conveyor and a first pressure sensor arranged above the base for the pressing rod to press against.

[0010] With the above solution, the pressure exerted by the silk reeling machine on the balance detection block can be transmitted to the pressing rod. Therefore, by detecting the pressure from the pressing rod through the first pressure sensor, it can effectively determine whether the balance detection block is pressed by the silk reeling machine. Since the pressing rod protrudes relatively from the side of the balance detection block, it can effectively improve the triggering accuracy of the first pressure sensor, thereby improving the triggering sensitivity of the detection mechanism.

[0011] Preferably, a controller is coupled to the first pressure sensor, and both the driving mechanism and the crawler conveyor are coupled to and controlled by the controller. When all the first pressure sensors detect the pressure from the corresponding pressing rods, the controller controls the driving mechanism and the crawler conveyor to operate.

[0012] With the above solution, when the silk reeling machine meets the conditions for balanced transfer before being lifted, it can automatically trigger the driving mechanism and the crawler conveyor to realize the automatic lifting and transfer of the silk reeling machine.

[0013] Preferably, a first bracket located between the first pressure sensor and the balance detection block is arranged on the base, and the pressing rod slides through the first bracket.

[0014] With the above - mentioned solution, the sliding fit between the extrusion rod and the first bracket can effectively improve the stability and smoothness of the extrusion rod during operation, thus ensuring the operation efficiency and accuracy of the detection mechanism.

[0015] Preferably, the elastic reset mechanism includes at least one set of guiding spring assemblies arranged between the first bracket and the balance detection block.

[0016] Preferably, the guiding spring assembly includes a guide rod arranged on the balance detection block and slidably passing through the first bracket, and an elastic member arranged on the guide rod to make the balance detection block tend to move away from the first bracket.

[0017] With the above - mentioned solution, the guiding spring assembly can effectively improve the reset efficiency and accuracy of the balance detection block, and ensure the stability of the balance detection block in the vertical direction, enabling it to effectively assist the detection module in detecting the friction coefficient of the conveyor belt of the crawler conveyor.

[0018] Preferably, a first anti - detachment member for preventing the guide rod from detaching from the first bracket is arranged at the end of the guide rod.

[0019] With the above - mentioned solution, the structure of the guiding spring assembly is more stable and not easily disassembled.

[0020] Preferably, the detection module includes a friction detection block longitudinally slidably arranged on the side of the balance detection block close to the crawler conveyor to abut against the conveyor belt, an extrusion member arranged on the side of the friction detection block close to the balance detection block, and a pressure sensor II arranged on the side of the balance detection block close to the friction detection block for the extrusion member to longitudinally extrude and output the measured pressure value signal. A controller for receiving the pressure value signal is coupled to the pressure sensor II, and a prompting unit is coupled to the controller;

[0021] When the pressure value measured by the pressure sensor II is less than the built - in threshold value of the controller, the controller controls the prompting unit to work; otherwise, the prompting unit does not work.

[0022] With the above - mentioned solution, when the detection module is in close contact with the conveyor belt of the crawler conveyor and the crawler conveyor starts to operate, the conveyor belt can generate a vertical downward relative displacement with the friction detection block, so as to drive the extrusion member on the friction detection block to longitudinally extrude the pressure sensor II on the balance detection block through the sliding friction between the two, and then indirectly judge the change of the friction coefficient of the conveyor belt surface through the change of the pressure value measured by the pressure sensor II. When the pressure value measured by the pressure sensor II is lower than the built - in threshold value of the controller, it indicates that the friction coefficient of the conveyor belt is too low, resulting in insufficient downward pressure applied to the friction detection block. At this time, the controller can control the prompting unit to work to remind the staff to replace the conveyor belt in time, thus ensuring the operation stability of the crawler conveyor.

[0023] Preferably, sliding rods and sliding sleeves are respectively arranged on the opposite surfaces of the balance detection block and the friction detection block. The sliding sleeves are longitudinally sleeved on the sliding rods, and a second anti-disengagement member for preventing the sliding sleeves from disengaging from the sliding rods is arranged at the ends of the sliding rods.

[0024] With the above solution, the sliding fit between the sliding rod and the sliding sleeve can effectively improve the stability and smoothness of the longitudinal micro-movement of the friction detection block, thereby effectively improving the detection efficiency and accuracy of the detection module. The second anti-disengagement member can effectively prevent the sliding sleeve from disengaging from the sliding rod, thereby ensuring the structural stability of the detection module.

[0025] Preferably, a wiping member is arranged on the side of the friction detection block away from the balance detection block. When the balance detection block is closely attached to the crawler conveyor in the running state, relative displacement is generated between the conveyor belt and the wiping member.

[0026] With the above solution, through the relative displacement between the wiping member and the conveyor belt, the dust on the surface of the conveyor belt can be effectively wiped off, thus eliminating the trouble of manual cleaning.

[0027] Preferably, a proximity switch for detecting whether the silk car is approaching to output an approaching signal is arranged on the guide rail. A controller for receiving the approaching signal is coupled to the proximity switch. The driving mechanism and the crawler conveyor are both coupled to and controlled by the controller;

[0028] When the proximity switch detects that the silk car is approaching, the controller controls the crawler conveyor to stop running and drives the crawler conveyor to descend through the driving mechanism.

[0029] With the above solution, after the silk car is transported onto the guide rail, the crawler conveyor can automatically stop and reset, thus facilitating the docking of a new silk car.

[0030] Due to the adoption of the above technical solutions, the present invention has remarkable technical effects: through the driving mechanism and the crawler conveyor, the silk car on the ground can be easily transferred to the support wheels of the guide rail, thereby effectively improving the operation efficiency and convenience and ensuring the safety of the silk car handling. The cooperation between the balance detection block and the detection mechanism can effectively determine the balance state of the silk car in the horizontal direction before being lifted, so as to prevent the silk car from having a large position deflection during the transfer process through the crawler conveyor after being lifted, thereby improving the accuracy of the silk car transfer. The elastic reset mechanism can not only drive the balance detection block to reset after the silk car is lifted to wait for the next round of balance detection, but also drive the detection module on the balance detection block to closely adhere to the conveyor belt of the crawler conveyor to obtain the friction coefficient of the conveyor belt, so as to facilitate the staff to replace the conveyor belt in time according to the attenuation of the friction coefficient, thereby ensuring the conveying efficiency and balance of the crawler conveyor, making the silk car more stable during the transfer to the support wheel and less likely to have a horizontal deflection.

[0045] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0046] As Figures 2 to 13 shown, a silk reel conveying device disclosed in this embodiment includes two guide rails 1 fixedly laid on the ground, and the two guide rails 1 are arranged in parallel. A plurality of support wheels 2 are rotatably arranged on the upper surface of each guide rail 1 along its own length direction to support the bottom of the silk reel 37, so that the rollers 29 at the bottom of the silk reel 37 are off the ground. A base 3 fixedly buried in the ground is arranged at the front end of the guide rail 1. The base 3 is located between the two guide rails 1, and its upper surface is flush with the ground. Above the base 3, there are two support members 4 corresponding to the two guide rails 1 one by one. Each support member 4 is in the shape of a horizontal cross bar and is respectively parallel to the corresponding guide rail 1. Crawler conveyors 5 are arranged on the opposite surfaces of the two support members 4, and the upper surface of the conveyor belt 10 of the crawler conveyor 5 is higher than the upper surface of the support member 4. A driving mechanism for connecting to the support member 4 to drive the crawler conveyor 5 to lift is arranged in the base 3. Specifically, the driving mechanism includes two oil cylinders 30 arranged in the base 3. The push rods 31 of the two oil cylinders 30 longitudinally slide through the upper surface of the base 3 and are respectively fixedly connected to the lower surfaces of the two support members 4. Two guide rods 32 are vertically arranged on the lower surface of each support member 4, and two guide holes 33 for the two guide rods 32 to slide through are opened on the upper surface of the base 3. In this embodiment, when the crawler conveyor 5 descends to the lowest position, the upper surface of its conveyor belt 10 is lower than the bottom of the silk reel 37. When the crawler conveyor 5 rises to the highest position, the upper surface of its conveyor belt 10 is flush with the upper surface of the support wheel 2.

[0047] In order to achieve the automatic operation of the driving mechanism and ensure the balance in the horizontal direction before the wire reel 37 is lifted, a balance detection block 7 is provided between each of the two crawler conveyors 5 and the corresponding guide rail 1. Both of the two balance detection blocks 7 are equipped with a detection mechanism for judging whether the balance detection block 7 is extruded by the wire reel 37. The detection mechanism includes a pressing rod 12 horizontally fixed on the side of the balance detection block 7 away from the crawler conveyor 5 and a first pressure sensor 13 provided above the base 3 for the pressing rod 12 to press against. The first pressure sensor 13 is preferably a pressure strain gauge. A controller 14 is coupled to the first pressure sensor 13. The controller 14 is preferably a single-chip microcomputer or a PLC. The driving mechanism and the crawler conveyor 5 are both coupled to and controlled by the controller 14. In this embodiment, the oil cylinders 30 in the driving mechanism are all coupled to the controller 14 through oil pumps 34 to achieve the precise rising and falling of the driving mechanism. When both of the two first pressure sensors 13 detect the pressure from the corresponding pressing rods 12, the controller 14 controls the driving mechanism to rise and controls the operation of the crawler conveyor 5.

[0048] In order to improve the stability and smoothness of the movement of the pressing rod 12 and ensure the detection height and stability of the first pressure sensor 13, a first bracket 15 is fixed on the base 3 between the first pressure sensor 13 and the balance detection block 7. The pressing rod 12 slidably passes through the first bracket 15. A second bracket 35 for installing the first pressure sensor 13 is also fixed on the base 3. The first pressure sensor 13 is installed on the side of the second bracket 35 close to the crawler conveyor 5.

[0049] In order to achieve the reset of the balance detection block 7, an elastic reset mechanism is provided on the detection mechanism. The elastic reset mechanism includes two sets of guide spring assemblies 16 provided between the first bracket 15 and the balance detection block 7 and located on the upper and lower sides of the pressing rod 12 respectively. Specifically, the guide spring assembly 16 includes a guide rod 17 horizontally fixed on the balance detection block 7 and slidably passing through the first bracket 15 and an elastic member 18 provided on the guide rod 17 to make the balance detection block 7 tend to move away from the first bracket 15. The elastic member 18 is preferably a compression spring sleeved on the guide rod 17. The two ends of the compression spring respectively press against the opposite surfaces of the first bracket 15 and the balance detection block 7. A through hole for the guide rod 17 to slidably pass through is formed in the first bracket 15. A first anti-disengagement member 19 with a width greater than the aperture of the through hole is provided at the end of the guide rod 17, thereby effectively preventing the guide rod 17 from disengaging from the first bracket 15.

[0050] In order to detect the attenuation degree of the friction coefficient on the surface of the conveyor belt 10, a detection module for contacting the conveyor belt 10 of the crawler conveyor 5 is provided on one side of the balance detection block 7 close to the crawler conveyor 5 to detect the change of the friction coefficient on the surface of the conveyor belt 10. Specifically, the detection module includes a friction detection block 20 longitudinally slidably arranged on one side of the balance detection block 7 close to the crawler conveyor 5 to abut against the conveyor belt 10, a pressing member 21 fixedly arranged on one side of the friction detection block 20 close to the balance detection block 7, and a second pressure sensor 22 arranged on one side of the balance detection block 7 close to the friction detection block 20 for the pressing member 21 to longitudinally press and output the measured pressure value signal. The second pressure sensor 22 is also preferably a pressure strain gauge. The controller 14 is coupled to the second pressure sensor 22 to receive the pressure value signal. A prompting unit 23 is coupled to the controller 14. The prompting unit 23 is preferably a buzzer.

[0051] In order to improve the stability and smoothness of the friction detection block 20 during operation, two vertical slide bars 24 are provided on one side of the balance detection block 7 close to the friction detection block 20. The lower ends of the slide bars 24 are fixed to a lower position of the balance detection block 7 through mounting seats 36. A supporting plate 38 for mounting the second pressure sensor 22 is connected between the two mounting seats 36. Correspondingly, two vertical sliding sleeves 25 are fixed on one side of the friction detection block 20 close to the balance detection block 7. The two sliding sleeves 25 are respectively longitudinally slidably sleeved on the two slide bars 24. A second anti-disengagement member 26 for preventing the sliding sleeve 25 from disengaging from the slide bar 24 is arranged at the end of the slide bar 24. The second anti-disengagement member 26 is preferably a screw, which is threadedly connected to the end of the slide bar 24 to play a role in longitudinal anti-disengagement. A space for the longitudinal movement of the pressing member 21 and the sliding sleeve 25 is maintained between the balance detection block 7 and the friction detection block 20.

[0052] The specific use process is as follows:

[0053] When transporting the silk reel 37, first push the silk reel 37 onto the base 3 and position the silk reel 37 between the two support members 4. When the silk reel 37 is pushed to the front end of the guide rail 1, the two fulcrums in the horizontal direction on its front side respectively press the two balance detection blocks 7, so that the two balance detection blocks 7 can overcome the elastic force of the elastic member 18 and retreat, and press against the corresponding first pressure sensors 13 through their respective pressing rods 12. When the two first pressure sensors 13 simultaneously detect the pressure from the corresponding pressing rods 12, it is determined that the silk reel 37 is in a balanced state. At this time, the controller 14 controls the operation of the two oil cylinders 30 through the oil pump 34 to lift the support member 4, thereby driving the crawler conveyor 5 to abut against the bottom of the silk reel 37 and lift the silk reel 37. When the silk reel 37 is lifted to the highest position, the bottom of the silk reel 37 is flush with the support wheels 2 on the guide rail 1, and the silk reel 37 is longitudinally separated from the balance detection blocks 7. In this state, the elastic reset mechanism drives the balance detection blocks 7 to reset, so that the friction detection blocks 20 on the detection module closely adhere to one end of the crawler conveyor 5 close to the guide rail 1, and then the controller 14 controls the operation of the crawler conveyor 5 to transfer the silk reel 37 onto the support wheels 2. During the operation of the crawler conveyor 5, the conveyor belt 10 can generate a longitudinal relative displacement with the corresponding friction detection blocks 20 to press down the friction detection blocks 20 through the sliding friction force, thereby driving the pressing member 21 on the friction detection blocks 20 to press against the second pressure sensor 22 above the supporting plate 38, so as to indirectly judge the change of the friction coefficient on the surface of the conveyor belt 10 through the pressure value measured by the second pressure sensor 22. In this embodiment, when the pressure value measured by the second pressure sensor 22 is less than the built-in threshold of the controller 14, it indicates that the friction coefficient on the surface of the conveyor belt 10 is lower than the normal level, and then the controller 14 controls the prompt unit 23 to work to remind the staff to replace the conveyor belt 10 in time, so as to avoid the transmission efficiency of the two crawler conveyors 5 differing too much and causing the silk reel 37 to deflect horizontally during the transmission process. On the contrary, when the prompt unit 23 does not work, it indicates that the crawler conveyor 5 is operating normally.

[0054] The above-mentioned electric control process can be realized by means of the built-in program of the controller 14, which belongs to the common knowledge in this field and will not be elaborated here.

[0055] In order to generate a more obvious pressing force at the front end of the silk reel 37, two pressing blocks 40 for pressing the two balance detection blocks 7 respectively are arranged in the horizontal direction at the front end of the silk reel 37. A pulley 39 is rotatably arranged on the side of the pressing block 40 away from the silk reel 37, and the rotation plane of the pulley 39 is vertically arranged to reduce the friction force when the pressing block 40 is longitudinally separated from the balance detection block 7, so that the lifting of the silk reel 37 is more smooth.

[0056] To improve the cleaning convenience of the conveyor belt 10, a wiping member 27 is provided on the side of the friction detection block 20 away from the balance detection block 7. The wiping member 27 is preferably a sponge cleaning pad or a brush, and is fixed to the friction detection block 20 by glue. In this embodiment, when the balance detection block 7 is in close contact with the crawler conveyor 5 in the running state, the conveyor belt 10 and the wiping member 27 generate relative displacement to automatically clean the surface of the conveyor belt 10 through the wiping member 27, thus eliminating the trouble of manual wiping.

[0057] If it is necessary to clean or replace the wiping member 27, first remove the two second anti-disengagement members 26 from the slide rod 24 to release the longitudinal locking between the sliding sleeve 25 and the slide rod 24, and then remove the friction detection block 20 together with the wiping member 27 upward. When installing the wiping member 27, respectively slide the two sliding sleeves 25 on the friction detection block 20 onto the two slide rods 24, and then reinstall the second anti-disengagement members 26 to longitudinally lock the sliding sleeve 25 on the slide rod 24, thereby completing the installation of the friction detection block 20 and the wiping member 27.

[0058] To achieve the automatic shutdown of the crawler conveyor 5 and the automatic reset of the drive mechanism, a proximity switch 28 for detecting whether the wire car 37 approaches and outputting a proximity signal to the controller 14 is provided on the guide rail 1. The distance between the proximity switch 28 and the front end of the guide rail 1 is equal to or slightly less than the length of the wire car 37, and it is fixed to the guide rail 1 by the third bracket 41. In this embodiment, when the proximity switch 28 detects that the wire car 37 approaches, it means that the wire car 37 has been transferred onto the guide rail 1, then the controller 14 controls the crawler conveyor 5 to automatically stop running and drives the oil cylinder 30 to descend by controlling the oil pump 34, so that the support member 4 and the crawler conveyor 5 automatically retract to the lowest position, thus facilitating the reception of the next wire car 37.
