The present invention particularly relates to a suspension cylindrical conveyor apparatus in which a conveyed object such as granular material or powdery material is wrapped inside and circulated in a state in which a fully sealed cylindrical belt is suspended on a wire rope. .

Belt conveyor devices for conveying goods by flat belts traveling on carrier rollers are well known in the art, but these flat belt conveyors cannot escape the transported objects, especially when transporting granular materials and the like. For example, it is extremely inappropriate for transporting long distances or transporting slopes. The development of cylindrical belt conveyors has been desired in order to alleviate various drawbacks of such flat belt conveyors.

This cylindrical belt conveyor installs a wire rope in connection with the conveying stroke of the belt, and suspends the belt on the rope to circulate at a constant speed so that the conveyor belt is kept in a cylindrical shape, and the transported object is cylindrical. It is transported in the state enclosed in the belt. In this way, the transported object can be completely prevented from being scattered during transportation. Also, by installing a wire rope like the ski lift of the ski lift, the belt can be transported over a long distance even in the ups and downs. .

In such a rope suspension cylindrical belt conveyor, it is necessary to maintain a high stability by running the rope and the belt in a balanced manner for reliable and favorable operation and for the operation of the belt with little damage, and to reduce the fluctuation of the belt as much as possible. And it is extremely important to reliably perform the belt detachment action for removing the belt from the belt or clamping the belt narrowing zone for suspending the belt in the rope before and after the object loading portion and the lowering portion.

In particular, with respect to the belt running, when driving only the suspension rope and following the belt to the running of the rope as seen in such a belt conveyor, it is mechanically horizontal to the rope (progression direction). And the load in the vertical direction to support the belt is loaded, which requires a large rope driving force, and the fatigue of the rope is large, which not only causes the short life, but also the starting, running, There is a tendency that the following belt responds to the stop and responds, and in particular, the difference in load between the load side carrying the transported object and the return side traveling without load, and the load by the ubiquity of the conveyed object on the belt also on the load side. The inertia of driving is extremely unbalanced due to the difference of At the same time, it is partially changed to cause the belt to swing and bend, and this may cause the belt clamping zone and the belt to fall off or slip off, and cause the belt conveyance speed to be hindered.

An object of the present invention is to increase the running stability of the belt and the rope in the suspension cylindrical conveyor apparatus, and to satisfy the driving force as little as possible.

Another object of the present invention is to provide a conveyor device with a long life and economical efficiency by reducing damage to the belt.

Another object of the present invention is to provide a novel belt detachment device which ensures the detachment action of the belt and the belt clamping zone.

Another object of the present invention is to provide a belt clamping zone which is secured by a belt and which is easily removable.

The feature of the present invention is that both ends of the cylindrical belt are also installed in the pulleys of the cylindrical belt in the same way as the wire ropes installed on the fleece, and both the wire ropes and the conveyor belt are driven in synchronism with each other. In this way, by synchronously interlocking the conveyor belt and the wire rope suspending the belt, the load weighted in the horizontal direction (progression direction) is equally distributed to both of them. The driving efficiency is remarkably improved, which makes it possible to operate at a sufficient speed with low driving force. In addition, the running position of the belt and the rope does not shift, and the impact due to the inertia caused at the start or the stop can be minimized, and the belt is free from swinging and torsion.

In addition, a feature of the present invention is that the belt hanger for suspending the conveyor belt from the rope is composed of a N-shaped suspension rod and a pair of bell-crank-shaped members that are received by the rope, The upper part is rotatably supported between the suspensions, and the two legs located at the inner side and intersecting with each other become the belt clamping intervals, and the two legs located at the outer side are the opening and closing operations. The press-fitting operation is pushed inward from both sides to simply open and close the clamping gripping, and the edge of the conveyor belt is clamped and the belt being held is separated.

Another feature of the present invention is that the belt opening and closing operation of the belt narrowing zone is completely automatic by a belt detacher composed of a pair of narrowing belts which are arranged on both sides of the conveyor belt traveling path and synchronously driven with the conveyor belt. To do it. The belt detacher is arranged at least before and after the transported portion and the lower portion of the transport belt of the conveyor belt, and the belt clamping zone passes between a pair of detachable belts. It is press-fitted and completely detaches the conveyor belt and the narrowing zone.

This invention is described in more detail with reference to the accompanying drawings showing the embodiment as follows.

The endless conveyor belt 4 is suspended and conveyed by the hanger 5 suspended from the rope 1 in the furnace substantially softly. The conveyor belt 4 is made of a flexible material such as rubber or elastic synthetic resin, and is explained in accordance with FIG. 7 shown in a state in which the structure is cylindrical, and is expanded on both sides of the belt 4. One ear 6, 7 is formed, and the inner wall of the ear 6, 7 is engaged with a hook in the cylindrical state of the belt 4, and the projection 8 for suppressing the opening of the belt to some extent. And the request 9 is formed. The belt 4 strongly suspends and suspends the neck 10 of the lower ear 6 and the lower port 7 by the clamping region 11.

This conveyor belt 4 is flat in the supply part 12 and the discharge part 13 of a conveyed material, and the linear conveyance part and drive of the return side 15 of the load side 14-load-free side in which the conveyed object was loaded are unloaded. In the turning parts 16 and 17 on the apparatus 2 side and the tension apparatus 3 side, it is bent cylindrically. In addition, immediately after the supply part 12 of the load side 14 and immediately before the discharge part 13 and also the return side 15 in connection with the conveyance direction X of the belt 4 (or the rope 1). Immediately after the driving turn 16 and immediately before the tension turn 17, a belt detachment has a function of picking up the belt 4 from the belt hanger 5 and a function of clamping the belt to the hanger 5, on the contrary. The apparatuses 18A, 18B, 18C, and 18D are respectively disposed. Therefore, the portion where the belt 4 is suspended by the hanger 5 is between the belt detaching devices 18A and 18B and between 18C and 18D, and the discharge part 13 and the driving turn part. The belt 4 and the belt hanger 5 between 18B and 18C via (16) and between the tension column 17 and 18D and 18A via the supply 12. And are completely separated.

At an appropriate location of the runway 1 of the rope 1, a support 19 provided with a guide wheel 65 for supporting the rope 1 at the upper end is disposed.

Since the outline of the configuration of the conveyor according to the present invention has been described above, the details of the individual constituent devices will be described below.

Referring to Fig. 2, the feed section 12 of the conveyed material and the tension column of the belt 4 and the rope 1 are U-shaped pulleys, which are recommended for the cable rope 1, and 21 are the belts. It is the recommended wheel of (4), and both are connected by the rotating shaft 92 and rotate interlock | linked.

As shown in the cross section in Fig. 5, the belt wheel 21 has a relatively wide width and is formed on the upper side with a request 23 engaged with the bulging ear 6 of the belt. 32 is a box-shaped slide frame which supports the pulley 20 and the wheel 21, and is hold | maintained so that sliding movement is possible to the fixed frame 33 formed as channel steel materials. 24 is a tension counterweight, which is a rope pulley 20 via a rope 27 installed between a wheel 26 disposed on a sliding frame 32 and a wheel 25 disposed on a fixed tower. And a tension force of appropriate strength is applied to the belt wheel 21.

The hopper 28 is installed in the feed supply part 12. The shape and structure of the hopper 28 are normally determined according to the kind of conveyed material like the chute 40 mentioned later. A plurality of carrier rollers 29 are arranged at appropriate angles in the frame object below the hopper 28.

The belt 4 removed from the belt hanger 5 by the belt detacher 18D on the belt return side 15 is turned by the turn wheel 21 in a cylindrical state to guide the roller at the inlet side of the supply part 12. The expanded ear parts 6 and 7 which are engaged by the 30 and the carrier rollers 29A and 29B are isolated, and are gradually discharged into a U-shape or a flat state in a cylindrical state, and are immediately provided to the feed hopper 28. Pass below At this time, a conveyance such as powder is supplied onto the belt, and the belt 4 is gradually bent again in a cylindrical shape by the carrier rollers 29C and 29D on the outlet side, and is guided by the guide roller 31. Engage the expanded ear parts 6 and 7, suspend the belt again with the hanger 5 by the belt detacher 18A on the load side 14, store the conveyed material inside the cylindrical belt, and discharge the 13).

Referring to Fig. 3, the discharge portion 13 and the drive turbine portion 16 of the conveyed material are represented by reference numeral 35, which is a drive pulley of the wire rope 1, and 36, which is a drive wheel of the conveyor belt 4. Both are connected by the drive shaft 37 and rotate interlockedly.

38 is a drive device, such as an electric motor, for example, The rotation drive force is transmitted to the drive side 37 through the electric belt or the gear 39, etc., and the wire rope 1 and the belt 4 are transmitted. The transfer jaw is synchronized to both of and. In addition, the rope drive pulley 35 and the belt drive wheel 36 form the same shape as the pulley 20 and the wheel 21 of the above-mentioned tension turbine. Both diameters are set so that the running speeds of the rope and the belt become the same. 40 is a chute disposed in the discharge part 13 and is provided on an appropriate frame stand 41. The discharge roller 42 located in the chute 40 and the tension roller 43 and the flow roller 44 located below the frame are respectively disposed in the frame stand 41. 46 is a flat weight. The cylindrical belt, which is released from the hanger 5 by the belt detacher 18B at the end of the lower expansion 14, is gradually opened and completely flattened and caught by the discharge roller 42. Release into). After that, the belt 4 in a flat state is installed in a Z shape while being properly tensioned in the tension roller 43 and the flow roller 44, and is gradually cylindrical again by the guide roller 45 through the discharge part 13. And the belt (8) of the expanded ear (6), (7) and the request (9) are engaged with each other, and are transferred to the return side via the above-described driving wheel (36) in a cylindrical state, and the belt is installed at the return start position It is clamped by the belt hanger 5 again by the machine 18C, and it is conveyed in a suspended state.

As shown in FIG. 6, the belt detacher 18 is a cylindrical belt provided with a pair of pinch belts 51 and the pinch belts 51 disposed to be symmetrically opposed along the conveying direction of the cylindrical belt 4. And a synchronous drive mechanism 68 for circulating driving synchronously with the feed speed of (4).

The pinching belts 51 are mounted on the plurality of V pulleys 50 as traveling materials, and are substantially parallel between the opposing surface portions 51A of the respective pinching belts 51 to be the passages of the belt pincers 11. A gap 52 is formed, the width of which is narrower than the outer width dimension between the left and right operating sections 73 of the sandwich strip 11 in the belt sandwiching state. In addition, a wide open entry guideway 53 is formed on the entry side of the hanger 5.

Each mounting pulley 54 of the pinching belt 51 is a driving pulley of the belt 51, which is a synchronous drive mechanism provided at the top by a drive shaft 56 having a material coefficient 55. (68).

Reference numeral 57 is a guide pulley of the wire rope 1, in which the tooth 58 is coaxially fixed, and a chain 60 is provided between the tooth 58 and the gear box 59. In addition, the gear 61 is fixedly installed at the upper end of the drive shaft 56, and a chain 62 is installed between the gear 61 and the gear box 59. Thus, the driving force of the rope 1 is transmitted to the chains 60 and 62, and finally to the pinching belt 51 via the shaft 56, and the rope 1 and the pinching belt 51 The registration is made at the feed rate. Therefore, the transmission ratios of the gears 58 and 61 and the drive pulley 54 are set such that both the rope 1 and the detachable belt 51 are at a constant speed. The detachable belt 51 is passed a chain 61, a tension disposed a rotation direction of its opposite respective drive pulley (54 ^A) to the conveying in the same direction of the surface portion (51A), (54 ^B) so that the opposite It is. Here, 66 and 67 are guide gears, and 65 is a guide pulley for wires.

When the effect of the belt detacher 18 is taken in the case where the belt clamping zone 11 is taken from the cylindrical belt 4 based on FIG. 6, the belt hanger 5 which suspended and supported the cylindrical belt 4 will be described. Is gradually entered from the introduction passage 53 and passes through the parallel passage 52, the left and right operating sections 73 are sandwiched between a set of detachable belts, pressed inward, and rotated back (in chain lines in FIG. 7). ), The blood stem 74 is opened to take the cylindrical belt 4.

At this time, since the detachable belt 51 is conveyed at the same speed as the hanger 5, the relative speed with the hanger 5 becomes zero, and the operation period 73 of the hanger over the parallel road 52 in the access road 53 is removed. Since it can hold | maintain firmly and can apply a pressing force in the direction orthogonal to the traveling direction Y, the most ideal desorption effect | action can be performed without torsion to a cylindrical belt or a hanger. In addition, the hanger 5, which is blood pressured due to the synchronous transfer between the hanger and the detachable belt 51, is hardly squeezed and twisted between the detachable belt 51 due to the self-propulsion force, Instead, the detachable belt 51 may be a V belt having wavy, sawtooth or square wave irregularities formed on the surface instead of the flat V belt on the surface.

The hanger 5 in which the pinching spaces 74 are opened is gradually inclined upward with respect to the surface of the cylindrical belt 4, and is completely separated from the cylindrical belt 4 to open it. Therefore, when the detachable belt 51 is inspected and disposed along the feed inclination of the hanger (that is, the wire rope), the cylindrical belt can be taken out or trapped by the hanger. In addition, the cylindrical belt 4 opened in the hanger is held by the guide roller 64 and conveyed to the work place of the next stage.

When the cylindrical belt 4 is pulled out by the hanger 5, the running direction of the wire rope 1 conveyor belt 4 and the detachable pinching belt 51 is opposite to that in FIG. 6, and the introduction path ( 53 is formed on the entry side of the hanger 5. Then, the hanger 5 has its belt interstices 74 opened by the pinching belt 51 to gradually approach the cylindrical belt 4 to insert the bulging portion 7 of the belt into the interstices 73 and the pinned belt ( At the rear end of 51), the neck portion 10 is pinched and supported by the belt between the pinching portions 74 at the moment when the operating portion 73 is released from the pinching belt 51.

As shown in FIG. 7, the belt hanger 5 includes a fixture 70 attached to the wire rope 1, an L-shaped suspension rod 71 in contact with the fixture, and the suspension rod 71. It is comprised as the belt clamping zone 11 arrange | positioned at the lower horizontal arm 72 of ().

The interstitial zone 11 is constituted by a pair of bell-crank-shaped members 75 which serve as the operating interposer 73 and the interposer interposer 74, and the interposer interposer 73 is outward and Interposed between the pincers 74 so as to be inward, they are arranged symmetrically, and the right angle portion 76 of the bell-crank-shaped member is attached to the horizontal arm 72 between the suspensions with a rotating material via the bracket 77. It is. The twist spring 79 is recommended for the rotation weight side 78, which gives the clamping force 74 in the conveyor belt pinching direction.

Denoted at 80 is a spring step retaining pin. The vicinity of the distal end of the interstitial trunk portion 74 is curved, and a belt narrowing plate 81 is installed at the distal end. The neck 10 of the belt is pinched and supported between the opposing pinching plates 81. When the left and right operating sections 73 are press-fitted inward, the pinching section 74 is rotated as indicated by the broken line in the figure, and the tip of the sandwiching section 74 is greatly opened, and the connector member fixed to the upper end of the suspension section 71 is fixed. In the 82, the twist spring 83 is incorporated so as to absorb the fluctuation in the moving direction of the hanger 5, so that the belt clamping action in the belt detacher can be reliably performed. Where 84 is the equilibrium weight. Such belt hangers are arranged on the rope 1 at appropriate equal intervals.

As described above, the conveyor apparatus of the present invention is driven by synchronously driving both the cylindrical belt 4 and the wire rope 1 supporting the belt. Therefore, the conveyor apparatus in the horizontal direction (moving direction) weighted only to the conventional rope is driven. The load is shared between the rope and the belt, respectively, and the driving efficiency is remarkably improved, and therefore, even a small driving force can be sufficiently driven.

In addition, as the load on the wire rope is reduced, the fatigue of the rope is reduced and the life is long. In addition, since the rope and the conveyor belt are driven at the same speed in synchronism, there is no deviation in the running position between the rope and the belt, and the impact on the rope is minimized due to the belt inertia at start and stop. As a result, the belt can be almost free from swinging and twisting. In addition, since the return side of the conveyor belt is also conveyed in a cylindrical shape, it is also possible to use the return belt for transporting a separate conveyed material. Of course, the reciprocating belt travel path is not necessarily parallel, and can be freely set economically on demand.

As shown in FIG. 5, when the conveyor belt 4 is recommended for the turning wheels 21 and 36 with the cylindrical state in the turning portions 16 and 17, the bent portion 90 of the belt 4 ) Is strongly crushed and crushed, and depending on the material of the belt, there is a risk of rupture damage due to the fragile habit of folding.

In order to avoid such an undesired phenomenon, as shown in FIG. 8, the belt 4 is recommended to be flat on the turbine circle 91. That is, the belt 4 close to each of the turrets of the turrets 16 and 17 is flat, and is recommended to the wheel 91 by vertically twisting the belt surface 92 by twisting approximately 90 degrees in the horizontal state of the belt surface. After passing through the turbine, the belt surface is returned to the horizontal state again. To change the belt surface from the horizontal state to the vertical state and from the vertical state to the horizontal state, an auxiliary guide roller or the like may be disposed. The turbine fins 91 used in this improvement device are attached as shown in FIG. 5 except that the far side width is widened.

In this way, by recommending the belt 4 in a flat state, damage to the belt due to the bending of the belt is completely eliminated, and the contact surface between the belt and the wheel is widened, so that the transmission efficiency of the belt driving force is increased, which is extremely effective and reliable belt operation To make it possible.
