Description

Technical Field

[0001] This invention relates to the field of rubber roller technology, and in particular to a rubber roller core removal device. Background Technology

[0002] Rubber rollers are roller-shaped products made of metal or other materials as the core and covered with rubber through vulcanization. They are mainly used in papermaking, dyeing and printing, grain processing, metallurgy, and plastics processing.

[0003] The rubber roller consists of a roller, a mandrel, and a nut or bolt that fixes the mandrel inside the roller. One end of the mandrel has a stepped surface, and the other end has threads. The threaded end passes through one end of the roller and exits through the other end. After the threaded end exits, a nut is screwed on, thus achieving the purpose of fixing the mandrel inside the roller.

[0004] However, in the existing technology, the removal of the core from the rubber roller often requires manual removal, which is inefficient and has high labor costs. Therefore, there is an urgent need for a new type of equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a rubber roller core removal device to solve the problems existing in the prior art, which has high core removal efficiency and high degree of mechanization.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] This invention provides a core-removing device for a rubber roller, comprising a fixing mechanism, a nut-removing mechanism, and a core-lifting mechanism. The fixing mechanism is equipped with a support station for supporting the rubber roller. The head end of the support station corresponds to the end of the mandrel with a nut, and the tail end of the support station corresponds to the other end of the mandrel. The nut-removing mechanism and the core-lifting mechanism can both be located at the head end of the support station. The nut-removing mechanism is used to unscrew the nut from one end of the mandrel, and before unscrewing the nut, the fixing mechanism fixes the mandrel. The core-lifting mechanism can at least partially eject the mandrel from the end of the roller. Before the mandrel is ejected, the fixing mechanism loosens the mandrel and fixes the roller.

[0008] Preferably, it also includes a fork-taking mechanism and a mandrel turnover trolley. The mandrel turnover trolley is located at the end of the support station. When the core-topping mechanism can only push the portion of the mandrel near the step out from the end of the roller, the fork of the fork-taking mechanism can hold the mandrel between the step and the roller and drag it toward the mandrel turnover trolley until the mandrel falls into the mandrel turnover trolley.

[0009] Preferably, the fixing mechanism includes a lower support member, an upper clamping member, and an upper clamping member driving device. The lower support member is fixedly installed, the support station is located on the lower support member, the upper clamping member is located above the lower support member, and the upper clamping member driving device can drive the upper clamping member to move downward until the roller and / or the mandrel are pressed against the lower support member.

The nut sleeve has a hole or groove that matches the outer circumference of the nut. The nut sleeve is fitted onto the nut under the drive of the linear feed drive device. The rotary drive device and the linear feed drive device work together to drive the nut sleeve to rotate and cause the nut to rotate outward from the mandrel.

[0011] Preferably, it also includes a receiving funnel, which is located below the head end of the support station.

[0012] Preferably, the nut sleeve is slidably mounted on a slide rail, the slide rail is fixedly mounted on the drive end of the rotary drive device, and an elastic element is provided on the side of the nut sleeve facing away from the nut, the elastic element being able to resist the nut from moving away from the nut.

[0013] Preferably, the core-lifting mechanism includes a core-lifting cylinder. The core-lifting cylinder and the nut-removing mechanism are both fixedly mounted on a lifting mechanism and are distributed vertically. The lifting mechanism drives the core-lifting cylinder and the nut-removing mechanism to move up and down so that the nut-removing mechanism and the core-lifting cylinder are aligned with the mandrel sequentially.

[0014] Preferably, it further includes a nut-removing mechanism, which includes a nut-removing fork plate, a fork plate lifting mechanism, and a fork plate linear movement mechanism. The nut-removing fork plate is disposed at the drive end of the fork plate lifting mechanism, and the fork plate lifting mechanism is disposed at the drive end of the fork plate linear movement mechanism. After the nut is removed from the threads on the mandrel, it remains attached to the end of the mandrel. After the fork plate lifting mechanism drives the nut-removing fork plate to insert into the inside of the nut, the fork plate linear movement mechanism drives the nut-removing fork plate to move outward and cause the nut to be removed from the mandrel.

[0015] Preferably, it also includes a stop pin and a pin driving mechanism, wherein the stop pin can be driven by the pin driving mechanism to the end of the support station and abut against the end of the mandrel that is provided with a stepped surface.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The purpose of this invention is to provide a rubber roller core removal device to solve the problems existing in the prior art, which has high core removal efficiency and high degree of mechanization.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] The nut in this invention can also be replaced by a screw nut.

[0029] This invention provides a core-removing device for rubber rollers, such as... Figures 1-3 As shown, it includes a fixing mechanism, a nut-removing mechanism 1, and a core-lifting mechanism 2. The fixing mechanism is equipped with a support station for supporting the rubber roller. The head end of the support station corresponds to the end of the mandrel with a nut, and the tail end of the support station corresponds to the other end of the mandrel. Both the nut-removing mechanism 1 and the core-lifting mechanism 2 can be set at the head end of the support station. The nut-removing mechanism 1 is used to unscrew the nut at one end of the mandrel from the mandrel. Before unscrewing the nut, the fixing mechanism fixes the mandrel. The core-lifting mechanism 2 can at least push a portion of the mandrel out from the end of the roller. Before the mandrel is pushed out, the fixing mechanism loosens the mandrel and fixes the roller.

[0030] The fixing mechanism in this invention can be used to fix the axial position of the mandrel so that the nut release mechanism 1 can drive the nut to rotate around the fixed axis of the mandrel. It can also fix the roller so that the subsequent core-ejecting mechanism 2 can eject the mandrel from the stationary roller.

[0031] In this embodiment of the invention, the mandrel and / or roller can be fixed by left-right clamping or top-bottom clamping. In order to facilitate the placement of the rubber roller, one component of the clamping assembly is often fixedly set and a support station is provided. After the workpiece is placed on the support station, the other clamping assembly is driven to move towards the fixed assembly to achieve clamping. Specifically, in this embodiment of the invention, the fixing mechanism includes a lower support member 4, an upper pressing member 5, and an upper pressing member driving device 6. The lower support member 4 is fixedly set, and the support station is set on the lower support member 4. The upper pressing member 5 is located above the lower support member 4. The upper pressing member driving device 6 can drive the upper pressing member 5 to move downward until the roller and / or mandrel is pressed against the lower support member 4.

[0032] The lower support 4 and the upper clamping member 5 can be V-shaped blocks.

[0033] The nut removal mechanism 1 in this invention is used to loosen the nut from the mandrel. The nut removal mechanism 1 needs to have a power source that outputs torque and an actuator that transmits torque. The actuator needs to establish a connection with the nut and the two cannot rotate relative to each other so that when the power source drives the actuator to rotate, it can drive the nut to rotate and thus unscrew the nut from the mandrel. However, since the nut will generate axial displacement when it is unscrewed, a linear feed drive device 14 is also needed to drive the actuator to move backward during the rotation process, so as to better realize the unscrewing of the nut.

[0034] Specifically, in this embodiment of the invention, the nut removal mechanism 1 includes a linear feed drive device 14, a rotary drive device 13, and a nut sleeve. The nut sleeve is connected to the drive end of the rotary drive device 13, and the rotary drive device 13 is disposed at the drive end of the linear feed drive device 14. The nut sleeve has a hole or groove that is adapted to the outer periphery of the nut. The nut sleeve is fitted onto the nut under the drive of the linear feed drive device 14. The rotary drive device 13 and the linear feed drive device 14 cooperate to drive the nut sleeve to rotate and drive the nut to rotate outward from the mandrel.

[0035] In the above embodiments, the rotary drive device 13 is preferably a rotary motor; the linear feed drive device 14 can be a linear motor, a cylinder or a hydraulic cylinder; when the cross-section of the nut is polygonal, the hole or groove in the nut sleeve is a polygon that matches its shape; when the cross-section of the nut is circular, a plane needs to be pre-machined on the outer wall of the nut, and a plane is also set at the relative position of the hole or groove in the nut sleeve, so as to achieve the purpose of transmitting torque.

[0036] In some other embodiments of the present invention, the nut sleeve is slidably disposed on a slide rail, the slide rail is fixedly disposed on the drive end of the rotary drive device 13, and an elastic element is disposed on the side of the nut sleeve facing away from the nut, the elastic element being able to resist the nut from moving away from the nut.

[0037] This embodiment enables the nut to have a certain degree of elasticity in the axial direction, thereby compensating for the defect that the speed of the linear feed drive device 14 is not matched with the speed of the nut unscrewing when driving linear movement, and improving the stability of operation.

[0038] In a specific embodiment of the present invention, the slide rail can be a guide post, a sliding hole is provided on one side of the nut sleeve, the nut sleeve is slidably disposed on the guide post, the elastic element is a spring, the spring is sleeved on the guide post, a limiting step is provided at the end of the guide post away from the nut sleeve, the limiting step and the nut sleeve limit the spring to the guide post, and in order to prevent the nut sleeve from slipping off the guide post, a limiting structure is also required at the end of the guide post.

[0039] In a specific embodiment of the present invention, as described in the above embodiments, when the nut sleeve is slidably arranged and an elastic element is provided on one side, the linear feed drive device 14 in the above embodiments can be omitted, and only the rotary drive device 13 is retained. In use, the nut sleeve is subjected to the axial extrusion force of the unscrewing nut and the compressed spring is shortened, which can also achieve the purpose of unscrewing the nut.

[0040] In the above embodiment, when the nut is unscrewed, it will be placed in the nut sleeve. To solve this problem, an elastic pin is also provided on the inside of the nut sleeve. That is, during the process of unscrewing the nut, the pin retracts under the pressure of the nut. When the nut is loosened, the elastic pin will push the nut out of the nut sleeve.

[0041] In addition to the above embodiments, in this embodiment of the invention, the end of the mandrel connected to the nut can be sequentially set as the optical shaft part and the threaded part, with the threaded part located inside the optical shaft part. The rubber roller core removal device in this embodiment also includes a nut removal mechanism, which includes a nut removal fork plate 9, a fork plate lifting mechanism 10, and a fork plate linear movement mechanism 11. The nut removal fork plate 9 is located at the driving end of the fork plate lifting mechanism 10, and the fork plate lifting mechanism 10 is located at the driving end of the fork plate linear movement mechanism 11. After the nut is removed from the thread on the mandrel, it is still hanging on the end of the mandrel. After the fork plate lifting mechanism 10 drives the nut removal fork plate 9 to be inserted into the inside of the nut, the fork plate linear movement mechanism 11 drives the nut removal fork plate 9 to move outward and cause the nut to be removed from the mandrel.

[0042] In this embodiment of the invention, in order to further prevent the spindle from rotating, a stop pin and a pin driving mechanism are also included. The stop pin can be driven by the pin driving mechanism to the end of the support station and abut against the end of the spindle that is provided with a stepped surface.

[0043] In use, the nut sleeve is driven by the linear feed drive device 14 to be sleeved on the nut and to give the mandrel an axial force, thereby making the end of the mandrel abut against the stop pin. The friction between the stop pin and the end face of the mandrel can resist the rotation of the mandrel.

[0044] The above embodiments do not include a receiving structure to receive the unscrewed nuts. Therefore, in this embodiment of the invention, the roller core removal device further includes a receiving funnel located below the head end of the support station. A receiving bucket is provided below the receiving funnel. In other embodiments, the receiving funnel can be omitted when space allows for a larger receiving bucket.

[0045] In this embodiment of the invention, when the length of the mandrel is short, less than 0.3m, the core-lifting mechanism 2 adopts a cylinder core-lifting mechanism. The cylinder can directly push the mandrel out of the roller, and a receiving mechanism, such as a receiving trolley, is provided below the support station or the end of the roller.

[0046] However, when the length of the mandrel exceeds 0.3m, such as the commonly used 1.2m mandrel, an extremely high impact force is required to eject the entire mandrel directly. This not only places extremely high demands on the cylinder but is also unsuitable for workshop applications, resulting in significant noise. Therefore, if... Figure 4 As shown, in this embodiment of the invention, the rubber roller core removal device further includes a fork-taking mechanism 7 and a core shaft turnover trolley 8. The core shaft turnover trolley 8 is located at the end of the support station. When the core-topping mechanism 2 can only push out the part of the core shaft near the step from the end of the roller, the fork of the fork-taking mechanism 7 can hold the core shaft between the step and the roller and drag it toward the core shaft turnover trolley 8 until the core shaft falls into the core shaft turnover trolley 8.

[0047] The fork-taking mechanism 7 includes a fork and a fork-taking drive device. The fork-taking drive device can drive the fork to move toward the mandrel and take the mandrel. After taking the mandrel, the fork-taking drive device can drive the fork to move away from the roller, thereby causing the mandrel to come out of the roller and thus achieving mandrel removal.

[0048] The mandrel turnover trolley 8 is equipped with a gentle descent ramp 16 on the side near the support station. After the end of the mandrel with threads comes out of the roller, it will fall onto the gentle descent ramp 16 and slide down the gentle descent ramp 16 to the bottom of the mandrel turnover trolley 8.

[0049] In this embodiment of the invention, the core mechanism 2 includes a core cylinder. The core cylinder and the nut removal mechanism 1 are both fixedly mounted on a lifting mechanism 12 and are distributed vertically. The lifting mechanism 12 drives the core cylinder and the nut removal mechanism 1 to move up and down so that the nut removal mechanism 1 and the core cylinder are aligned with the mandrel in sequence.

[0050] Of course, the top core cylinder and the nut release mechanism 1 can also be driven by a corresponding lifting mechanism 12. However, this not only increases the cost, but also the two lifting mechanisms 12 have the same path, which is very easy to cause motion interference. Therefore, the present invention preferably uses a lifting mechanism 12 to drive the top core cylinder and the nut release mechanism 1 to lift at the same time.

[0051] In this embodiment of the invention, each component is integrated on one rack 3 or can be separately installed on multiple racks 3.

[0052] In this embodiment of the invention, the fork-taking mechanism 7 includes a vertical fork 20, an autonomous moving platform, a vertical fork lifting drive device, a horizontal fork 21, and a horizontal fork lateral moving drive device. The autonomous moving platform is movably mounted on a support structure in directions away from and towards the support station. The vertical fork lifting drive device is fixedly mounted on the autonomous moving platform. The vertical fork 20 is fixedly mounted on the drive end of the vertical fork lifting drive device. The horizontal fork lateral moving drive device is fixedly mounted on the autonomous moving platform. The horizontal fork 21 is fixedly mounted on the drive end of the horizontal fork lateral moving drive device. The horizontal fork lateral moving drive device can drive the horizontal fork 21 to move along the horizontal direction, perpendicular to the axis of the spindle, and fork onto the spindle along the horizontal direction.

[0053] The above embodiment solves the defects of the top core mechanism 2 being unable to push the core shaft a long distance due to the rubber roller sticking to the core shaft, and the gap between the step at the end of the core shaft and the V-block being too small, making it difficult for the shift fork to be inserted horizontally and from below due to the obstruction of the V-block. Therefore, in use, the vertical shift fork 20 of the fork-taking mechanism 7 picks up the core shaft from the top of the core shaft. However, after the core shaft has moved a certain distance, there is no structure on the vertical shift fork 20 to resist the weight of the core shaft. Therefore, it is necessary to replace the horizontal shift fork 21 to pick up the core shaft. Therefore, a liftable core shaft support roller 15 is also provided on the back side of the descent ramp 16, that is, on the side facing the support station. The core shaft support roller 15 is driven by a cylinder to move up and down. After the core shaft has moved a certain distance from the roller, the core shaft support roller 15 rises to abut the bottom surface of the core shaft, and then the shift fork of the fork-taking mechanism 7 is replaced.

[0054] The workflow of this invention embodiment is as follows:

[0055] Step 1: Place the rubber roller on the support station;

[0056] Step 2: The fixing mechanism secures the rollers and mandrel;

[0057] Step 3: The drive device drives the nut sleeve in the nut release mechanism 1 to align with the nut;

[0058] Before step four, drive the stop pin down to abut one end of the spindle;

[0059] Step 4: The nut release mechanism 1 releases the nut until it is hooked onto the optical shaft at one end of the spindle;

[0060] Step 5: The nut removal mechanism 1 moves to a position away from the nut, and the nut removal mechanism removes the nut from the mandrel, causing the nut to fall into the receiving funnel below.

[0061] Step 6: The top core mechanism 2 moves to align with the mandrel;

[0062] Before step seven, drive the stop pin upwards to move it away from the spindle;

[0063] Step 7: The core-lifting mechanism 2 pushes the core outward;

[0064] Step 8: The forklift mechanism 7 picks up the mandrel and drags it outward until the mandrel is completely removed from the roller.

[0065] The devices for lifting and horizontal movement described in the above embodiments of the present invention can all be accomplished using cylinders or linear motor modules.

[0066] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
