Description

  The present invention is a belt conveyor that conveys various items to a high position. More specifically, the belt conveyor can be moved with respect to the use position, and the height of the discharge end can be adjusted by arbitrarily adjusting the inclination angle in the conveyance direction. The present invention relates to a belt conveyor that can be set according to use conditions.

  As shown in FIG. 6, the belt conveyor 1 as described above forms an endless belt 4 by winding an endless belt 4 around a group of rollers 3 mounted side by side on a long frame 2 whose rear end is grounded. A position in the middle of the lower part of the conveyor body 5 is supported by a pair of support legs 6 on both sides. A movable leg member 8 that supports the frame is coupled to each other at the lower end on the ground side via a slide mechanism that is movable in the vertical direction, and a wheel 9 is attached to the lower end coupling portion to open the leg in a V shape. The inclination angle of the supported conveyor body 5 can be changed by changing the open leg angle of the both side support legs 6 by winding or unwinding the wire 11 by the winch 10 fixed to the frame 2. You have me.

  Conventionally, a mechanism for changing the leg angle of the support legs 6 on both sides is that a winch 10 is fixedly arranged near the upper end of the pivot-side leg member 7 in the frame 2 of the conveyor body 5, and the wire drawn from the winch 10 11 is connected to the upper end side of the movable leg member 8, and when the wire 11 is wound by the winch 10, the upper end of the movable leg member 8 approaches the pivoting leg member 7. As a result, the leg opening angle of the support leg 6 is narrowed, and the inclination angle is tightened by raising the middle of the conveyor body 5 so that the discharge end can be raised.

  Further, when the wire 11 is fed out by the winch 10, the upper leg of the movable leg member 8 is separated from the pivoting leg member 7, so that the opening angle of the support leg 6 is widened and the intermediate part of the conveyor body 5 is lowered. The inclination angle becomes loose, and the discharge side end can be lowered.

  By the way, since the support leg 6 in the belt conveyor 1 as described above supports the middle of the conveyor body 5 in a state where the leg is opened in a V shape, a load in the leg opening direction is always applied. Will be supported by the winch 10 through the wire 11, but in addition to the weight of the conveyor body 5, the weight of the conveyed product and the impact at the time of unloading the conveyed item are applied in the direction of the opening with respect to the support leg 6. The winch 10 supporting the load becomes large and a large capacity must be used. Therefore, not only the overall weight of the belt conveyor 1 is increased and the moving operation is inconvenient, but also the belt conveyor. There is a problem that the production cost of the is high.

  Accordingly, an object of the present invention is to fix the upper end of the movable leg member of the support leg so as not to move in the open leg direction with respect to the frame without hindering the adjustment of the opening and closing of the support leg. It is possible to provide a belt conveyor capable of reducing the size of a winch to be used by supporting the load in the opening leg direction with the support legs themselves.

  In order to solve the above problems, the present invention supports a position in the middle of the lower part of the conveyor body that grounds one end of the frame with a pair of support legs on both sides, and the support legs pivot to a fixed position on the frame. A fixed leg and a leg that is movable in the length direction of the frame are joined together at the lower end on the grounding side, and the open leg angle of the supporting legs on both sides is wound by a winch fixed to the frame. In a belt conveyor that can change the inclination angle of the supported conveyor body by changing the take-up or feeding, the length of the groove is placed inside the both-side groove forming the frame of the conveyor body. Set stoppers that can move in the vertical direction and bite into the upper and lower surfaces of the groove shape so that it does not move in the opening direction of the support leg at an arbitrary inclination angle with respect to the groove shape. And a contact piece that presses the stopper so as to bite into the upper and lower surfaces of the groove-shaped member with the moving force of the movable side leg in the direction of the leg of the support leg at the upper end of the movable side leg. Is adopted.

  The stopper has a width that allows a sufficient space in the vertical gap of the frame shape member of the frame and a length longer than the interval between the upper and lower surfaces of the groove shape material. Formed in a parallelogram shape with inclined surfaces abutting the upper and lower surfaces of the groove shape material in the inclined state located in the front of the leg opening direction, and a structure for attaching a pressing screw for fixing to the side surface of the groove shape material to this stopper It can be.

  Moreover, it is good also as a structure which connected the upper end of the movable side leg material of the said stopper and the said both-sides support leg via the connection member so that it might move integrally in the length direction of a channel shape material.

  Here, the conveyor body is mounted with a large number of rollers arranged side by side on a long frame for grounding the tail head provided on the rear end side, and an endless belt is wound around the outside of the roller group and provided in the tail head. The belt is driven by a motor.

  The support leg is made of a metal pipe, and the pivoting leg is attached to the arm plate with its upper end fixed to the groove of the frame by pin connection, and the movable leg is pivoted to the side of the upper arm plate. The lower surface of the channel member is supported by the ridged roller, the upper end is movable in the length direction of the channel member, and the lower end of the pivot side leg member and the movable side leg member are pivoted together by the shaft. A grounding wheel is attached to the coupling shaft.

  The support legs on both sides are connected to each other by the side rails at the pivot side and between the side legs at the movable side, and the tip of the wire drawn from the manual or electric winch It is connected to the top horizontal rail that joins.

  The groove forming material forming the frame of the conveyor body has a cross-sectional shape in which one side surface is opened up and down leaving a wall, and the frame is formed by arranging the open side surface in parallel on both sides. The stopper incorporated in the inside of the channel is not separated from the outside by the upper and lower ribs, and the connecting member that connects the stopper and the upper end of the movable leg member is a spring or a strong wire. Pin or pressing screw projecting on the outer surface of the arm plate provided on the upper end of the movable leg member and a pin projecting or projecting at a position lower than the center on the outer surface of the stopper. It is stretched between the end portions of the contact pieces so that the upper end of the movable side leg member and the stopper can be integrally moved in the length direction of the channel member.

  Further, the abutting piece protrudes at an upper position on the inner surface of the arm plate provided at the upper end of the movable leg member, and presses the position near the lower end of the stopper fixed at an arbitrary position in the leg opening direction. Therefore, the pressing force acts on the stopper so that the upper and lower ends of the stopper bite into the upper and lower surfaces of the channel material, so that the upper end of the movable leg member does not move to the open leg side with the stopper and the abutting piece By fixing to, the support leg itself supports the load.

  According to the present invention, the upper side of the groove shape member is prevented from moving in the opening direction of the support leg at an arbitrary inclination angle with respect to the groove shape member inside the both side groove shape members forming the frame of the conveyor body. A stopper acting so as to bite into the lower surface is incorporated, and the stopper is bited into the upper and lower surfaces of the channel-shaped material at the upper end of the movable side leg member by the moving force of the movable side leg member toward the supporting leg opening leg direction. Since the contact piece that is pressed and inclined is provided, the support leg is opened in a V shape to support the conveyor body, and the contact piece of the movable side leg member is a stopper with a moving force in the opening direction. Can be fixed so that the upper end of the movable leg is not moved in the direction of the opening leg, and the support leg itself can Can support shocks when unloading, and support legs open and close Since not applied high load on the winch operating the, will be able to use a winch of small capacity compact, it is possible to realize the weight reduction and cost reduction of the belt conveyor.

  In addition, the stopper can move the movable leg in the closing leg direction, and if the stopper is moved along the length direction of the channel, the movable leg can be moved in the leg opening direction. The support leg can be opened and closed by operating the winch, and the height of the discharge side end of the conveyor body can be adjusted without hindrance. If they are connected so as to move together in the vertical direction, there is always a stopper in the vicinity of the upper end of the movable leg when adjusting the leg angle of the movable leg, so that the adjustment of the leg angle can be performed efficiently.

  In addition, since a pressing screw for fixing the side surface of the channel is attached to the stopper, it can be fixed so that the stopper does not move to any position on the channel, and it can be moved simply by selecting the fixing position of the stopper. The leg angle of the side legs can be set.

Yes.

  The winch 27 is fixed to the lower surface of the mounting seat fixed between the groove members 33 in the frame 22 of the conveyor main body 23, and is disposed in the vicinity of the upper end pivot stop portion of the pivot leg member 25 of the support leg 24. Yes.

  As shown in FIGS. 2 to 4, it is possible to move in the longitudinal direction of the groove member 33 inside the both-side groove member 33 that forms the frame 22 of the conveyor body 23, and to the groove member 33. A stopper 40 that works to bite into the upper and lower surfaces of the groove-shaped member 33 so as not to move in the opening direction of the support leg 24 at an inclination angle of is attached to the upper end of the movable-side leg member 26. A contact piece 42 is provided to press the stopper 40 into the upper and lower surfaces of the channel member 33 by the moving force of the leg member 26 in the opening leg direction of the support leg 24.

  The stopper 40 has an L-shaped cross section having a width that fits with a sufficient clearance in the vertical direction of the groove member 33 of the frame 22 and a length that is longer than the interval between the upper and lower surfaces of the groove member 33. The stopper 40 is formed as a parallelogram with an inclined surface 40a acting in the direction of biting in contact with the upper and lower surfaces of the groove shape member 33 in an inclined state where the upper end is located in front of the shape member 33 with respect to the shape member 33. Further, a pressing screw 43 for fixing the side surface of the channel member 33 is attached.

  As shown in FIG. 2, the channel member 33 forming the frame 22 of the conveyor body 23 has a square cross-sectional shape in which one side surface is opened up and down leaving the wall 33a, with the open side surface facing outward. The frame 40 is formed by joining in parallel arrangement on both sides, and the stopper 40 incorporated in the inside of the groove member 33 is prevented from being detached to the outside by the upper and lower rib walls 33a in the inclined state. When the fixing pressing screw 43 is screwed into the stopper 40 in the state from the side surface where the groove member 33 is opened, and the tip of the pressing screw 43 is brought into contact with the other side surface of the groove member 33, the stopper 40 is moved up and down the wall 33a. By being pressed against the inner surface of the groove member 33, the groove member 33 is fixed.

As the connecting member 41, the illustrated spring, a strong linear object, a flexible string-like object, or the like is used. In the illustrated example, the connecting member 41 protrudes from the outer surface of the arm plate 34 provided at the upper end of the movable leg member 26. The pin 44 protruding from the outer surface of the stopper 40 at a position lower than the center is connected by a spring so that the stopper 40 is integrated with the upper end of the movable leg member 26 in the length direction of the channel member 33. I try to move.

  The connecting member 41 may connect the pressing screw 43 of the stopper 40 and the abutting piece 42 and omit the pins 44 and 45 described above.

  Further, a contact piece 42 protrudes at an upper position on the inner surface of the arm plate 34 provided at the upper end of the movable leg member 26, and the contact piece 42 opens the position near the lower end portion of the stopper 40. By pressing in the direction, the upper and lower ends of the inclined stopper 40 are caused to bite into the upper and lower surfaces of the groove member 33, and the stopper 40 is fixed so as not to move to the open leg side, thereby supporting legs 24. Supports the load of the conveyor body 23.

  The belt conveyor 21 of the present invention is configured as described above, and the conveyor main body 23 can be arbitrarily set by grounding the wheel 37 of the support leg 24 and the tail wheel 30 of the tail head 29 which are opened in a V shape. The belt 32 is driven in a state where it is supported at an inclination angle and the upper discharge end of the conveyor body 23 faces the unloading position, and the conveyed product supplied from the tail head side is conveyed to the unloading position.

  In the belt conveyor 21, as shown in FIGS. 2 (a) and 2 (b), the stopper 40 is in an inclined state in which the upper end is located in front of the conveying direction with respect to the length direction of the channel member 33, and the pressing screw 43 is A contact piece 42 provided at the upper end of the movable leg member 26 of the support leg 24 that is screwed and fixed to the channel member 33 and that opens is in contact with the stopper 40 and presses the lower part of the stopper 40 in the leg opening direction. 4A, the pressing force acts so that the upper and lower end portions of the stopper 40 bite into the upper and lower surfaces of the groove member 33, whereby the stopper 40 is moved to the movable leg 26. The upper end of the support leg 24 is fixed so as not to move to the open leg side, the V-shaped open leg angle of the support leg 24 is fixed, and the support leg 24 supports the load by itself. Wipe through the wire 28 connected to the upper end. So as not to apply a large load to the switch 27.

  In the belt conveyor 21, in order to change the inclination angle of the conveyor body 23 according to the height condition of the unloading position, the movable leg 26 of the support leg 24 is moved in the closing leg direction as shown in FIG. In some cases, the upper discharge end is raised, and as shown in FIG. 5A, the movable leg 26 of the support leg 24 is moved in the opening direction to lower the upper discharge end.

  In the case of increasing the former upper discharge end, if the winch 27 is operated to wind the wire 28 while the pressing screw 43 of the stopper 40 is loosened, the upper end of the movable leg 26 is pulled and pivoted. The support leg 24 approaches the stop-side leg member 25 and pushes up the conveyor body 23 as the opening leg angle becomes narrow.

  At this time, the stopper 40 connected to the upper end of the movable leg member 26 via the connecting member 41 is along the length direction of the channel member 33, and the lower end side thereof is pulled in the closing leg direction of the support leg 24. Therefore, the upper end of the movable leg member 26 and the stopper 40 move without trouble in the direction of the closed leg, and the upper discharge end of the conveyor body 23 reaches a predetermined height. The winding of the wire 28 by the winch 27 is stopped.

  The stopper 40 is movable when the pressing screw 43 is screwed and fixed to the channel member 33 at the moved position, and the contact piece 42 provided at the upper end of the movable leg member 26 is brought into contact with the lower portion of the stopper 40. The force in the leg opening direction of the side leg member 26 is applied to the stopper 40 via the contact piece 42, and the pressing force of the contact piece 42 causes the upper and lower ends of the stopper 40 to bite into the upper and lower surfaces of the channel member 33. Since the upper end of the movable leg member 26 is fixed in the opening direction with respect to the channel member 33, the adjusted leg angle of the support leg 24 is maintained.

  In order to lower the upper discharge end of the latter, first, as shown in FIG. 4 (b), with the pressing screw 43 of the stopper 40 loosened, the stopper 40 is set along the length direction of the channel member 33. Then, when the winch 27 is operated and the wire 28 is drawn out, the upper end of the movable leg member 26 extends in the leg-opening direction by the leg-opening action of the load applied to the support leg 24 that opens in a V-shape. If the upper discharge end of the conveyor body 23 is lowered and reaches a predetermined height due to the movement and the opening leg angle of the support leg 24 is widened, the feeding of the wire 28 by the winch 27 is stopped.

  In this state, the stopper 40 is inclined with respect to the length direction of the groove member 33, the position near the lower end thereof is brought into contact with the contact piece 42, and the pressing screw 43 is screwed in, as shown in FIG. If it returns to the state, the force in the leg opening direction of the movable leg member 26 is applied to the stopper 40 via the contact piece 42, and this stopper 40 acts so that the upper and lower ends bite into the upper and lower surfaces of the channel member 33. Since the upper end of the movable leg member 26 is fixed in the leg opening direction, the leg opening angle of the support leg 24 after adjustment is maintained.

  Thus, after adjusting the leg opening angle of the conveyor body 23, the upper end of the movable leg member 26 is fixed to the groove member 33 via the stopper 40 so as not to move in the leg opening direction. The conveyor body 23 and the weight of the conveyed product and the impact when the conveyed product is unloaded can be supported by itself, and a large load is not applied to the winch 27 for operating the opening leg and the closing leg of the supporting leg 24 via the wire 28. Therefore, the winch 27 to be used can be reduced in size and capacity.
