Description

  The present invention relates to a return roller in a belt conveyor.

  As is well known, the belt conveyor spans an endless belt between a head pulley and a tail pulley, the carrier-side back surface of the belt is supported by a carrier roller, and the return-side surface of the belt is supported by a return roller. .

  The carrier roller and the return roller are replaced each time a failure occurs that hinders smooth rotation.

  Thus, for example, Patent Literatures 1, 2, and 3 have been proposed on the carrier side as methods that can be easily replaced, but Patent Literature 4 exists on the return side.

  By the way, the method of patent document 1, 2, and 3 is the structure of a carrier side roller, Comprising: It cannot apply to a return side roller.

  The configuration of Patent Document 4 is a system in which two return rollers are arranged on the upper and lower sides and the upper and lower return rollers are switched.

  However, since the lower return roller until it is replaced (due to a failure, etc.) is in a standby state, the fallen particles adhering to the surface of the belt during the standby fall and adhere to the surface of the return roller. To do.

Since this fallen adhering material is only on the upper peripheral surface of the return roller, the belt traveling by the adhering material adhering to only a part of the peripheral surface of the return roller will wave, and the bearing portion of the support shaft of the return roller accompanying this wave motion A shock occurs in the bearing and a failure occurs in the bearing.
Therefore, the present invention is to provide a return roller that solves the above-mentioned problems.

  In order to solve the above-described problems, the present invention provides a guide rail provided below a return side belt in a belt conveyor so as to cross at right angles to the traveling direction of the belt, and the belt using the guide rail as a guide. A slider provided so as to slide in the width direction, a return stand provided upright from both ends of the slider, and a return roller horizontally mounted by engaging both ends of the support shaft with the upper ends of both return stands. A holding means provided at one end of the guide rail so that one end of the slider at the time of completion of pushing back is engaged, and a restraint provided to prevent the slider from being pushed back to the other end of the slider. The structure which consists of a means is employ | adopted.

  As described above, according to the return roller of the belt conveyor of the present invention, the return roller can be pulled out together by releasing the restraint and pulling out the slider, so that the return roller can be replaced very easily. When the slider is pushed back after replacement of the return roller and the slider is prevented from being pulled out by the restraining means, the holding means and one end of the slider are engaged with each other. Therefore, the slider is stably placed on the guide rail. Can be stationary.

It is a front view which shows embodiment of this invention. It is a side view same as the above. It is the same part notch front view. It is the same part notch side view. It is the longitudinal section side view. It is a partially notched front view which shows the state pulled out.

Embodiments of the present invention will be described with reference to the accompanying drawings.
A shown in FIGS. 1 to 5 is a belt conveyor.

  As is well known, the belt conveyor A is constructed by spanning an endless belt 1 between a head pulley and a tail pulley (not shown), and the carrier side rear surface (lower side surface in the drawing) of the belt 1 is arranged in front and rear. It is supported by the carrier roller 2 arranged as described above.

  Further, a guide rail 3 is provided on the return side surface (the lower side surface in the drawing) of the belt 1 so as to cross the belt 1 at right angles to the traveling direction of the belt 1 and to be arranged in parallel at a predetermined interval.

  Furthermore, a slider 4 that slides in the width direction of the belt 1 using the guide rail 3 as a guide is provided.

  The guide rail 3 uses an angle material in the case shown in the drawing, and both ends are attached to the lower end of the support bracket 6 with the upper ends attached to both side frames 5 of the conveyor A so that the ridge line is on the upper side (upward) (by welding bolts or the like) The slider 4 is fixed and mounted using an angle material so as to overlap the upper side of the guide rail 3, but is not limited, and a hard synthetic resin or the like other than the steel material may be used. In short, the slider 4 can be slid using the guide rail 3 as a guide.

  4, 5, and 6, an inclusion B such as a mat having excellent sliding property is attached between the guide rail 3 and the slider 4 (attached to either the guide rail 3 or the slider 4 with an adhesive or the like. ) Is provided, it is possible to ensure smooth sliding of the slider 4.

  The slider 4 is provided with a return roller 7 that can be replaced (replaced).

  As described above, the exchangeable support system of the return roller 7 is, as is well known, the outer periphery of both ends of the support shaft 10 of the return roller 7 in the notch 9 facing downward from the upper end surface of the return stand 8 rising from both ends of the slider 4. The groove 11 provided at the surface facing position is engaged with the groove 11 in a meshing manner, thereby supporting the spindle 10 in a fixed position and in a non-rotating state.

  One end of the guide rail 3 is provided with a holding means C that stops the longitudinal movement of the belt 1 and the vertical movement of the belt 1 by engaging one end of the slider 4 at the end of pushing back.

  In the illustrated case, the holding means C is constructed by attaching an embedding piece 12 made of an angle or a plate piece to the upper side of one end of the guide rail 3 with a gap into which the one end side of the slider 4 is fitted. It may be adopted.

  Further, the other end side of the slider 4 is provided with a restraining means D that prevents the slider 4 from being pulled out under the state of engagement between the end of the pushed back slider 4 and the holding means C.

  In the case shown in the figure, the restraining means D is provided with a window 13 through which the slider 4 and the return roller 7 pass when the support metal fitting 6 is pulled out. Although the lid 14 is provided and the lid 14 is fixed to the support fitting 6 via the screw 15 after the slider 4 is pushed back, the slider 4 is prevented from sliding in the pulling direction. May be adopted. In short, the restraining means D prevents the slider 4 from being pulled out.

  If the handle 16 is provided on the lid 14 as shown in the figure, the drawer 4 can be easily pulled out and pushed back.

  Further, in the illustrated case, one return roller is supported by the slider 4, but a plurality of sliders can be arranged in parallel, for example.

  In the figure, reference numeral 21 denotes a support stand for the carrier roller 2, and this stand 21 is raised on a bar member 22 installed on the frame 5. Reference numeral 23 denotes a screw into which the screw 15 is screwed.

With the above configuration, when the restraint by the restraining means is released and the slider 4 is pulled out using the guide rail 3 as a guide, the return roller 7 on the slider 4 is also pulled out to the side of the belt conveyor A together with the slider 4, so that it is pulled out. It is very easy to recover when the return roller 7 is removed and replace a new return roller, and can be performed safely without any danger.
Moreover, the replacement work can be smoothly performed in a short time with a small number of people.

  Of course, a large-scale scaffolding is not necessary and can be exchanged by a small number of people, so that costs can be reduced and operation can be resumed in a short time. Can be eliminated.

  Further, after the replacement, the return roller 7 is pushed back together with the slider 4, and the holding means C and one end side of the slider 4 are engaged with each other and the movement of the slider 4 with respect to the guide rail 3 is stopped by the restraining means D. It is also possible to ensure the rotation of the roller 7 at a stable fixed position.
