Description

TECHNICAL FIELD

[0001] The utility model belongs to mechanical technical field relates to the elevator. BACKGROUND

[0002] The push plate type elevator is very common feeding equipment, especially for rod workpieces or shaft workpieces, which comprises a rack provided with a hopper and a lifting plate assembly arranged in the hopper, and a batch of workpieces are poured into the hopper, and then the workpieces in the hopper are lifted by the lifting plate assembly in a horizontal state. In order to realize the automatic conveying of the workpieces, a conveying belt is generally arranged on the top back of the rack, and the workpieces are lifted to the top of the rack by the lifting plate assembly and then fall into the conveying belt.

[0003] For conventional long rod or long shaft workpieces, because both ends are of the same size, the mechanical hand grasps either end, so there is no need to pay attention to the sorting problem when feeding. However, for long rod or long shaft workpieces with one large end and one small end, the large end of the workpiece is randomly oriented when it is lifted by the lifting plate assembly in a horizontal state, but the grasping position of the mechanical hand is required according to the processing requirements (such as when the large end needs to be processed, the grasping position of the mechanical hand is the small end; when the small end needs to be processed, the grasping position of the mechanical hand is the large end), so the large end of each such workpiece conveyed to the mechanical hand for grasping must be oriented in the same direction. The current market elevator cannot automatically sort such workpieces, so workers must first arrange such workpieces in the hopper according to the grasping requirements of the mechanical hand to ensure that the workpieces are in the specified direction when lifted onto the conveying belt. SUMMARY

[0004] The utility model aims at the above problems existing in the prior art, and provides an elevator, which solves the problem that long rod or long shaft workpieces with large and small ends cannot be automatically sorted.

[0005] The utility model discloses the purpose can be realized through the following technical scheme:

[0006] The elevator comprises a rack provided with a hopper, a lifting plate assembly arranged in the hopper and a material receiving guide rail fixed to the top back of the rack, the two ends of the material receiving guide rail are an inner end and an outer end respectively, characterized in that the material receiving guide rail is provided with a displacement slot along the length direction thereof, the displacement slot is vertically through and penetrates the two ends of the material receiving guide rail, a long strip type swing arm is arranged in the displacement slot and located at the upper slot opening thereof, the swing arm is hingedly connected with the inner end of the material receiving guide rail, a movable support is slidably connected to the back of the material receiving guide rail along the length direction thereof, the rack or the material receiving guide rail is connected with a first driving piece for driving the swing arm to swing and a second driving piece for driving the movable support to move, the movable support is connected with a material pushing plate, and the material pushing plate is located above the material receiving guide rail.

[0007] The lifting machine is mainly used for workpieces with one end large and one end small and in the shape of a long rod or a long shaft. When in use, the outer end of the material receiving guide rail is connected with the conveying belt. Batch workpieces are poured into the material bin of the rack, and then the lifting plate assembly moves upward and lifts the workpieces upward. The length of the workpieces is relatively long, and the lifting plate assembly only lifts one workpiece in a horizontal state upward each time.

[0008] After the lifting plate assembly lifts the workpieces to the top of the rack, the workpieces in the horizontal state roll downward onto the material receiving guide rail. Since the material receiving guide rail is provided with a clearance groove, when the workpieces fall onto the material receiving guide rail, the small end of the workpieces will fall downward into the clearance groove, and the large end of the workpieces will be clamped at the slot opening of the clearance groove, so that the workpieces will be vertically hung on the material receiving guide rail. It should be noted that in the initial state, the first driving member controls the swing arm to swing to the state that the outer end is in the lower swing position, so that the swing arm is not located in the slot opening of the clearance groove as a whole, and the clearance is provided for the workpieces to change from the horizontal state to the vertically hung state. After the workpieces are in the hung state, the first driving member drives the swing arm to swing around the hinge point of the swing arm and the material receiving guide rail to the state that the swing arm is located in the slot opening of the clearance groove as a whole, and in the process of swinging, the swing arm will abut against and push the small end of the workpieces falling into the clearance groove to move upward. After the swing arm is swung into place, the workpieces are adjusted by the swing arm to the horizontal state with the small end facing the outer end of the material receiving guide rail and the large end facing the inner end of the material receiving guide rail. Then, the second driving member drives the movable support to move towards the outer end of the material receiving guide rail, and in the process, the material receiving plate pushes the workpieces in the horizontally adjusted state towards the outer end of the material receiving guide rail onto the conveying belt for conveying. Through the combination of the clearance groove and the swing arm, the orientation of the large end of each lifted workpiece can be adjusted, so that each workpiece can be fed in the horizontal state with the large end facing the same direction, without the need for manual adjustment of the orientation, greatly improving the production efficiency.

[0009] In the lifting machine described above, the material receiving guide rail includes two vertically arranged and opposite side plates and two horizontally arranged adjusting plates, the two adjusting plates are connected to the upper sides of the two side plates, and the two adjusting plates can move along the width of the material receiving guide rail and can be positioned with the side plates after moving. The gap between the two adjusting plates is the upper slot opening of the clearance groove.

[0010] By moving the two adjusting plates along the width direction of the material receiving guide rail, the size of the upper slot opening of the clearance groove can be adjusted to adapt to workpieces of different sizes, improving the applicability.

[0011] In the lifting machine, the movable support comprises a first sliding base and a second sliding base, the first sliding base is connected with the material receiving rail, the second sliding base is slidingly connected on the top of the first sliding base along the length direction of the material receiving rail, the top of the first sliding base is further connected with a third driving member for driving the second sliding base to slide, the material pushing plate is vertically arranged and connected with the second sliding base, and the second sliding base is connected with a fourth driving member for driving the material pushing plate to move up and down.

[0012] When the workpiece is lifted up by the lifting plate assembly, the orientation of the large end of the workpiece is random, which can be oriented towards the outer end of the material receiving rail or the inner end of the material receiving rail. If the large end of the workpiece is oriented towards the outer end of the material receiving rail, the position of the workpiece is relatively close to the outer end of the material receiving rail after the workpiece is in the hanging state, and the workpiece cannot be adjusted to the horizontal state by directly controlling the swing of the swing arm.

[0013] Therefore, after the workpiece is in the hanging state, the first sliding base is driven by the second driving member to move towards the outer end of the material receiving rail, so that the material pushing plate moves to the front of the large end of the workpiece, and then the material pushing plate is driven by the fourth driving member to move to the lower end opposite to the large end of the workpiece along the length direction of the material receiving rail, and then the first sliding base is driven by the second driving member to move towards the inner end of the material receiving rail, so that the lower end of the material pushing plate abuts against the large end of the workpiece and pulls the workpiece towards the inner end of the material receiving rail. After the workpiece is pulled, the fourth driving member controls the material pushing plate to move upwards to the original position. Then, the swing arm is driven by the first driving member to swing to adjust the workpiece to the horizontal state with the small end oriented towards the outer end of the material receiving rail and the large end oriented towards the inner end of the material receiving rail. Finally, the second sliding base is driven by the third driving member to move towards the inner end of the material receiving rail, so that the material pushing plate moves to the rear of the large end of the workpiece after being adjusted to the horizontal state, and then the material pushing plate is driven by the fourth driving member to move to the lower end opposite to the large end of the workpiece along the length direction of the material receiving rail, and finally the first sliding base is driven by the second driving member to slide, so that the material pushing plate pushes the workpiece to the conveying belt.

[0014] Through the above arrangement, the workpiece can be reliably adjusted regardless of the orientation of the large end when the workpiece is lifted up, and the reliability of the work is ensured.

[0015] In the lifting machine, the second sliding base comprises a seat plate arranged horizontally and a mounting plate arranged vertically, the material pushing plate is located on one side of the mounting plate and the lower end of the material pushing plate extends out of the mounting plate, the seat plate is provided with a strip-shaped first adjusting hole along the width direction of the material receiving rail, and the mounting plate and the seat plate are fixedly connected by a first adjusting screw, the rod portion of the first adjusting screw passes through the first adjusting hole and is threadedly connected in the mounting plate.

[0016] When the first adjusting screw is loosened, the mounting plate can be adjusted along the width direction of the material receiving guide (i.e. the front-to-back direction of the rack) through the cooperation of the first adjusting screw and the first adjusting hole. The material pushing plate is connected to the mounting plate, so adjusting the position of the mounting plate along the width direction of the material receiving guide is equivalent to adjusting the position of the material pushing plate along the width direction of the material receiving guide, thereby ensuring that the position of the material pushing plate can adapt to workpieces of different sizes.

[0017] In the above-described lifting machine, the material pushing plate comprises parallel plate body one and plate body two. Plate body one is driven by the fourth driving member, and the upper end of plate body two is provided with a strip-shaped second adjusting hole in the vertical direction. Plate body one and plate body two are fixedly connected by a second adjusting screw, the rod portion of which passes through the second adjusting hole and is threadedly connected in plate body one.

[0018] When the second adjusting screw is loosened, plate body two can be adjusted along the vertical direction through the cooperation of the second adjusting screw and the second adjusting hole. The material pushing plate is composed of plate body one and plate body two, so adjusting the position of plate body two along the vertical direction is equivalent to adjusting the position of the lower end of the entire material pushing plate to adapt to workpieces of different sizes.

[0019] In the above-described lifting machine, the swing arm is provided with a matching groove, which is arranged along the upper surface of the swing arm, and the groove bottom wall of the matching groove is a circular arc surface.

[0020] When the swing arm contacts the workpiece in the vertical hanging state, the matching groove will play a role in centering the workpiece along the width direction of the material receiving guide, thereby ensuring that the central axis of each workpiece can be basically kept consistent during conveying.

[0021] In the above-described lifting machine, the inner end of the swing arm extends out of the inner end of the material receiving guide. The rack is fixedly connected with a mounting seat on the side corresponding to the inner end of the material receiving guide, and the mounting seat is lower than the material receiving guide. The first driving member is connected to the mounting seat, and the first driving member is a pneumatic / hydraulic cylinder. The piston rod end portion of the first driving member is fixedly connected with a hinge joint, and the inner end of the swing arm is hinged to the hinge joint.

[0022] The inner end of the swing arm extends out of the inner end of the material receiving guide, and then the mounting seat is fixedly connected to the side of the rack corresponding to the inner end of the material receiving guide. The mounting seat is lower than the material receiving guide, and the first driving member is connected to the mounting seat and cooperates with the inner end of the swing arm. In this way, the swing of the swing arm can be controlled, and at the same time, the first driving member does not occupy the internal space of the accommodation groove, thereby not affecting the vertical hanging of the workpiece.

[0023] Compared with the prior art, the elevator can adjust the workpiece horizontally rolling into the receiving guide rail to a vertical hanging state by the accommodation slot and adjust the workpiece in the vertical hanging state to be horizontal and adjust the orientation of the large end of the workpiece by the swing arm, so that each workpiece can be fed in the horizontal state with the large end oriented in the same direction, without manual reversing adjustment, greatly improving the production efficiency.
