Description

  The present invention is a roller-type conveyance device provided with a plurality of conveyance rollers for conveying a workpiece, and detects the amount of deformation of each conveyance roller and manages the state of each conveyance roller. It is about the system. In particular, in a roller-type conveyance device provided with a plurality of conveyance rollers, the deformation amount in each conveyance roller is detected, the deformation state in each conveyance roller is determined, the state of each conveyance roller is appropriately managed, and the conveyance roller It is characterized in that it is possible to easily replace a deteriorated transport roller at an appropriate time before it becomes unusable due to deformation.

  In processing in a heat treatment furnace or the like while transporting a work, conventionally, a plurality of transport rollers are arranged in the transport direction of the work through a required interval, and the work is placed by the transport rollers arranged in this way. 2. Description of the Related Art Roller type transport devices that are transported are widely used.

  Here, when a plurality of transport rollers are transported in a heat treatment furnace or the like by a roller-type transport device in which a plurality of transport rollers are arranged in the transport direction of the workpiece as described above, the transport rollers are gradually heated by heat or the like. There is a problem in that it deteriorates and the transport roller is broken or deformed, making it difficult to properly transport the workpiece by the roller-type transport device.

  And conventionally, as shown in Patent Document 1, an electrode portion is formed on a part of the outer peripheral surface on one end side of each roller, and the electrode portion is formed on the outer periphery on the forming side for each roller. While a contactor that contacts the surface is arranged, each contactor is connected to an electrode part associated with the rotation of each transport roller and a detection means that detects electrical continuity and non-conduction through the contactor. A device in which breakage of a roller is detected by a detection means has been proposed.

  However, when detecting that each roller is broken by the detection means in this way, in a heat treatment furnace or the like, it is necessary to stop the work of conveying the workpiece by the roller when the roller breaks. , Because productivity is greatly reduced and the roller cannot be predicted to break, it is impossible to predict how much of the replacement roller should be prepared, There was a problem that became difficult.

  Further, in Patent Document 2, when a workpiece is transported by a roller-type transport device provided with a plurality of transport rollers in a heat treatment furnace or the like, the transport rollers are gradually deformed by heat or the like, so the transport rollers are rotated. A control means for controlling the rotation of the motor to be driven is provided, and this control means is provided with a center-of-gravity positioning means for aligning the center of gravity of the transport roller and a bend correction means for the transport roller forcing the bend of the transport roller. Things have been proposed.

  And in the thing of this patent document 2, when a conveyance roller deform | transforms with heat in the heat processing furnace etc., rotation of the motor which rotates a conveyance roller by the said control means is controlled, and a gravity center position shifts | deviates. It has been proposed that the deformed transport roller is maintained in a predetermined state for an appropriate time to correct the deformed transport roller.

  However, in order to correct the deformed transport roller by controlling the rotation of the motor that rotates the transport roller to correct the state of the transport roller deformed by heat in this way, the control is very troublesome and time-consuming. There is a problem that productivity is greatly reduced. In addition, it may be difficult to appropriately correct the deformed transport roller as described above. In this case, it is necessary to replace the deformed transport roller. Similarly, it is impossible to predict how much the transport roller for replacement should be prepared, and there is a problem that preparation for replacing the transport roller becomes difficult.

  In the transport roller state management system according to the present invention, the deformation amount of the roller shaft in the transport roller is detected by the deformation amount detection sensor as described above, and the deformation amount of the roller shaft in the transport roller detected by the deformation amount detection sensor. Based on the above, the determination device determines the deformation state of the transport roller, and the management device manages the state of each transport roller based on the determination result by the determination device. At this stage, it becomes possible to easily confirm the deformation state, the number and position of the transport rollers to be replaced.

  As a result, in the present invention, the deteriorated conveying roller in the roller type conveying apparatus can be replaced at an appropriate time, and the productivity in the heat treatment furnace or the like can be prevented from decreasing.

In embodiment of this invention, it is a schematic sectional drawing of the vertical direction along the longitudinal direction which showed the state which conveys a workpiece | work with the roller-type conveying apparatus in a heat processing furnace, and heat-processes. In the above-described embodiment, a plurality of transport rollers are arranged in the transport direction in which the workpiece is transported through a required interval, and the deformation amount of the roller shaft in each transport roller is composed of a bending amount measurement sensor and an elongation amount measurement sensor. A configuration in which a deformation amount detection sensor detects the deformation state of the transport roller based on the detected deformation amount of the roller shaft, and the determination device determines the deformation state and communicates the determination result to a management device that manages the state of each transport roller. It is a partial cross-section explanatory drawing of the horizontal direction along the shown longitudinal direction. In the above-described embodiment, taking one conveyance roller in the roller-type conveyance device as an example, the deformation amount of the roller shaft in the conveyance roller is detected by a deformation amount detection sensor including a bending amount measurement sensor and an elongation amount measurement sensor. The direction intersecting the conveyance direction showing a configuration in which the determination device determines the deformation state of the conveyance roller based on the detected deformation amount of the roller shaft, and communicates the determination result to the management device that manages the state of the conveyance roller. FIG. It is a schematic sectional drawing of the vertical direction which shows the roller type conveying apparatus which winds and conveys a strip | belt-shaped workpiece | work.

  Hereinafter, the state management system of the conveyance roller which concerns on embodiment of this invention is demonstrated concretely based on an accompanying drawing. The transport roller state management system according to the present invention is not limited to the one shown in the following embodiment, and can be implemented with appropriate modifications within the scope not changing the gist of the invention.

  Here, in FIG. 1, when the work W is transported from the carry-in port 11 toward the carry-out port 12 on both sides in the longitudinal direction of the heat treatment furnace 10, a plurality of transport rollers 21 are transported as the roller-type transport device 20. They are arranged in the direction with a required interval. The workpiece W is described here as a strip-shaped steel strip (metal strip), but any workpiece can be used as long as it can be conveyed by a roller.

  And in the said roller-type conveyance apparatus 20, as shown in FIG.2 and FIG.3, the both ends along the conveyance direction of the workpiece | work W of the heat processing furnace 10 are shown for the edge part of the both sides of the roller shaft 21a in each conveyance roller 21. The bearing members 22 and 23 provided outside the side walls 13 are rotatably held through the side walls 13.

  Here, at one end side of the roller shaft 21a in each of the transport rollers 21, the end of the roller shaft 21a is held by a commercially available bearing member 22 that is rotatably held so as not to be displaced in the vertical direction and the axial direction. I try to let them. On the other hand, on the other end side of the roller shaft 21a in each transport roller 21, a commercially available bearing member 23 is rotatably held so that the end of the roller shaft 21a can extend in the axial direction or bend in the vertical direction. I try to keep it.

  Further, in this embodiment, as described above, each of the transport rollers 21 rotatably held by the bearing member 23 so that the end of the roller shaft 21a can extend in the axial direction or bend in the vertical direction. As the deformation amount detection sensor 30 for detecting the deformation amount in each transport roller 21 on the other end side of the roller shaft 21a, the roller shaft 21a rotatably held on the bearing member 23 through the side wall 13 as described above. At the end, a bending amount measuring sensor 31 that measures the amount of bending in the vertical direction of the roller shaft 21a and an elongation amount measuring sensor 32 that measures the elongation amount of the roller shaft 21a are provided.

  In this embodiment, the amount of bending in the vertical direction of the roller shaft 21a in each conveyance roller 21 measured by each bending amount measurement sensor 31 and each conveyance roller 21 measured by each elongation amount measurement sensor 32 are described. The axial extension amount of the roller shaft 21a at each is output to the discriminating device 40, and the vertical bending amount of the roller shaft 21a at the transport roller 21 and the axial extension amount of the roller shaft 21a at the transport roller 21 are Based on the above, the determination device 40 determines the deformation state of each transport roller 21.

  Next, the amount of bending in the vertical direction of the roller shaft 21 a in each conveyance roller 21 measured by each bending amount measurement sensor 31 in this way, and the axial direction of the roller shaft 21 a in each conveyance roller 21 measured by each elongation amount measurement sensor 32. The result of the deformation state of each transport roller 21 determined by the determination device 40 based on the amount of elongation of the image is output to the management device 50 by the communication means 60 such as the Internet, and the result output from the determination device 40 is Based on this, the management device 50 manages the result of the deformation state of each transport roller 21 and manages the replacement time in each transport roller 21.

  Thus, based on the deformation amount in each conveyance roller 21 measured by the deformation amount detection sensor 30 using each bending amount measurement sensor 31 or each elongation amount measurement sensor 32, the determination device 40 determines the amount in each conveyance roller 21. If the deformed state is determined and the result of the deformed state of each transport roller 21 is managed by the management device 50 based on the determination result by the determining device 40, each transport roller 21 is deformed and cannot be used. In the previous stage, it becomes possible to easily check the replacement time of each transport roller 21 and the number and position of the transport rollers 21 to be replaced.

  Here, when the determination result by the determination device 40 is communicated to the management device 50 by the communication means 60 as described above, the management device 50 is installed in a manufacturer or the like that manages the maintenance of the transfer roller 21, so Before the rollers 21 are deformed and cannot be used, the deformation state and the number and position of the transport rollers 21 can be easily confirmed, and the number of transport rollers 21 to be replaced is prepared in advance. In the type conveying device 20, the deteriorated conveying roller 21 is appropriately detected, and an appropriate number of conveying rollers 21 can be immediately replaced at an appropriate time.

  The “appropriate time” referred to here corresponds to a maintenance date in which it is predetermined to stop the operation in the operation of the facility using the roller type conveying device 20. Since the user of the facility plans the production amount including the maintenance date, the production amount does not decrease if the facility user can exchange the maintenance date using the present invention.

  Further, the communication means 60 for communicating the determination result may be any means such as wired communication, wireless communication, and the Internet, and the determination device 40 and the management device 50 may be in a remote place. Similarly, the deformation amount detection sensor 30 and the discriminating device 40 may be connected by communication means and arranged at a remote place.

  In addition, the management device 50 may be installed in a parts manufacturer or the like that manufactures the transport roller 21, and the transport roller 21 to be replaced in advance is manufactured in a necessary number, and delivered to the user of the facility by the maintenance date. Good. By doing so, it is possible to prevent the facility user from forgetting to place an order and not replacing it, thereby preventing the facility from causing trouble.

  Further, in the present embodiment, the mode of transporting the workpiece W on the transport roller 21 has been described, but “transport” transports the strip-shaped workpiece W ′ as shown in FIG. 4 in addition to such a configuration. Any form may be used, such as a form of carrying while being wound around the roller 21 ′.

  As a result, in this embodiment, only the transport roller 21 deteriorated in the roller-type transport device 20 provided in the heat treatment furnace 10 can be easily replaced at an appropriate time, and the productivity in the heat treatment furnace 10 is reduced. Can be prevented.

  Moreover, although the heat processing furnace 10 was taken as an example here, it is needless to say that the heat treatment furnace 10 can also be adopted as a transport roller for other facilities.
