Description
Technical Field
The present invention relates to a roller cap attached to an end of a ceramic roller of a continuous firing furnace provided with a roller conveyor, and a roller conveyor and a continuous firing furnace provided with the roller cap.
Background
A continuous firing furnace such as a roller kiln used as an industrial furnace includes a large number of ceramic rollers arranged in parallel along a conveying direction of a material to be fired, and the material to be fired is conveyed and fired by rotation of the rollers.
In such a roller kiln, a joint structure between a roller and a drive shaft capable of transmitting rotational drive even if the roller and the drive shaft of the drive device are eccentric is required. Further, the roll may be warped or broken due to high temperature during use or load of the material to be fired, and in this case, the roll needs to be replaced during operation. Further, since glaze or the like applied to the body to be fired adheres to the roller and causes troubles such as meandering of the body to be fired or lifting of the platen to the front, the roller needs to be periodically removed and cleaned. Therefore, the joint structure between the roller and the drive shaft is required to be a structure that is easy to assemble.
In such a joint structure, a member for connection is required at an end portion of the ceramic roller, but the following functions are required for such a member. That is, it is required to align the core of the ceramic roll with the external driving center, to prevent the ceramic roll from being damaged, to prevent the roll from being processed excessively, to transmit the driving force without looseness due to thermal expansion or the like, to reduce the processing cost, and to facilitate the attachment and detachment of the roll.

Detailed Description
The embodiments of the present invention are described in detail below. The present invention is not limited to the illustrated embodiments, and design changes can be made arbitrarily without departing from the technical scope described in each claim. The roller cap 1 according to the present embodiment is a metal member attached to an end portion of the ceramic roller 2 in a roller conveying device of the continuous burning furnace. The roller cap 1 is attached to the ceramic roller 2 so that rotation of a driving device (not shown) is transmitted to the ceramic roller 2 via a drive transmission mechanism (joint structure) 3.
The roller cap 1 includes: a cylindrical portion 10 having one end 10a into which an end of the ceramic roller 2 is inserted and fitted; a slit 11 extending from one end 10a of the cylindrical portion 10 toward the other end 10b to a middle of the cylindrical portion 10 in the longitudinal direction; a slit hole 12 formed at the closed end 11a of the slit 11 and having a diameter d longer than the width w of the slit; and a pressing member 5 disposed between the closed end 11a and the open end 11b of the slit 11 in the longitudinal direction of the cylindrical portion 10, for pressing the cylindrical portion 10 in the radial direction of the cylindrical portion 10.
Since the roller cap 1 includes the slits 11 and the notch holes 12 in the cylindrical portion 10, when the end portions of the ceramic rollers 2 are inserted into the roller cap 1, the slits 11 are spread around the notch holes 12 as fulcrums, so that the ceramic rollers 2 are not damaged, and the mounting can be performed easily and reliably. Further, since the pressing member 5 that presses the cylindrical portion 10 in the radial direction of the cylindrical portion 10 is provided, the driving force can be reliably transmitted to the ceramic roller 2 without being loosened by thermal expansion or the like.
As shown in fig. 4, a pair of slits 11 is preferably provided, and the pair of slits 11 are disposed at positions facing each other in the front view of the roller cap 1. By forming such a structure, when the roller cap 1 is inserted and fitted to the end of the ceramic roller 2, the roller cap can be more easily attached without displacement or skew.
As shown in fig. 1, the thickness T1 of the one end 10a of the cylindrical portion 10 is preferably smaller than the thickness T2 of the other end 10b of the cylindrical portion 10. Such a structure can be realized by cutting the inner surface of the metal pipe. By forming such a configuration, the one end portion 10a side is more easily expanded than the other end portion 10b side, and when the roller cap 1 is inserted into the end portion of the ceramic roller 2, a more effective spring function can be achieved.
In the present embodiment, the pressing member 5 is a male screw that is screwed into a female screw hole 19 formed in the cylindrical portion 10 and extending in the radial direction. By using the female screw hole 19 and the male screw, the processing cost is low, the roller can be easily attached and detached, and the looseness caused by thermal expansion and the like can be more reliably prevented. It is preferable to provide a recess 13 formed on the outer circumferential surface of the cylindrical portion 10 for receiving a screw head of the male screw. By providing such a recess 13, when the ceramic roller 2 rotates, the screw head of the male screw can be prevented from interfering with other members, and the appearance of the mounting structure of the roller cap 1 can be improved.
As shown in fig. 4 and 5, when the inner diameter of one end 10a of the cylindrical portion 10 is D1 and the outer diameter of the end of the ceramic roller 2 is D2, D1-D2 are preferably 0mm to 0.8 mm. If D1-D2 is less than 0mm, the roller cap 1 is difficult to insert into the end of the ceramic roller 2, and the ceramic roller 2 may be easily damaged. When D1 to D2 exceed 0.8mm, the roll caps 1 are easily loosened when inserted into the end portions of the ceramic rolls 2.
The roller cap 1 further includes a first through-hole 17 communicating with the through-hole 21 provided in the ceramic roller 2 on the side of the one end portion 10a of the cylindrical portion 10, and the ceramic roller 2 and the roller cap 1 are locked by inserting the locking pin 41 through the through-hole 21 provided in the ceramic roller 2 and the first through-hole 17. The roller cap 1 further includes a second through-hole 18 communicating with a through-hole provided in the drive transmission mechanism 3 for rotating the ceramic roller 2 on the other end portion 10b side of the cylindrical portion 10, and the drive transmission mechanism 3 and the roller cap 1 are locked by inserting the locking pin 42 through the through-hole provided in the drive transmission mechanism 3 and the second through-hole 18. For example, R-clips can be used as the locking pins 41 and 42. In fig. 1, only the shaft of the drive transmission mechanism is shown.
The roller cap 1 of the present embodiment is manufactured simply and at a reduced cost because the concave portion 13 is cut by cutting or the like only the inner surfaces of the metal pipe on the one end portion 10a side and the other end portion 10b side, and the first through hole 17, the second through hole 18, and the female screw hole 19 are penetrated in the radial direction of the metal pipe. Further, since the through-holes 21 are formed only in the ceramic roller 2, the risk of damage to the ceramic roller during processing can be suppressed.
