Description

TECHNICAL FIELD

[0001] The present application relates to the field of transportation equipment, in particular to an AGV material transfer device. BACKGROUND

[0002] AGV (Automated Guided Vehicle) refers to a transportation vehicle equipped with an automatic guiding device such as an electromagnetic or optical device, capable of traveling along a specified guiding path and having safety protection and various transfer functions. AGV is widely used in the fields of factory logistics automation and automatic assembly line, for example, in the processing and production of paper industry, workers place raw paper on the AGV device, and use the AGV device to transport the raw paper to the processing production line to make finished paper through processes such as crushing, screening and concentrating, and then use the AGV device to realize automatic unloading and storage of the finished paper.

[0003] With the gradual improvement of environmental protection requirements and the continuous enhancement of national environmental protection consciousness, now paper processing plants use more recycled waste paper, shredded paper and other raw materials for paper production and processing; these raw materials are light, thin and fine, and when transported by AGV devices and transported to the processing production line, the raw materials are easy to scatter from the AGV device to the external environment such as the factory floor, making the surrounding environment messy, affecting the work experience of personnel and easily breeding bacteria affecting people's health. SUMMARY

[0004] In order to improve the scattering of raw materials to the surrounding environment during raw material transfer and improve the cleanliness of the surrounding environment, the present application provides an AGV material transfer device.

[0005] The AGV material transfer device provided by the present application adopts the following technical scheme:

[0006] An AGV material transfer device, comprising a box body and an AGV trolley, the box body comprising a base frame and a turnover frame hingedly connected to the top edge of the base frame on one side, the top of the turnover frame being provided with a storage space for storing raw materials, and the bottom of the base frame being provided with a bottom space for the AGV trolley to enter;

[0007] The AGV trolley comprises a trolley body and a lifting and turnover mechanism mounted on the trolley body, the lifting and turnover mechanism being used to stepwise drive the box body to rise and the turnover frame to turn over; the lifting and turnover mechanism comprises a jacking seat arranged on the trolley body in a lifting manner, the top of the jacking seat being provided with a negative pressure insertion pipe, and the negative pressure insertion pipe being connected with a negative pressure mechanism for providing negative pressure;

[0008] The inner wall of the storage space is embedded with a cover, and the cover is located at the port position of the storage space; the side of the cover away from the storage space is connected with an extension pipe, and the end of the extension pipe away from the cover extends to the bottom space; in the transfer state, the negative pressure insertion pipe is matched and inserted into the extension pipe.

[0009] By adopting the technical scheme, the AGV device can be used to store raw materials such as waste paper and shredded paper. After the AGV car automatically moves to the bottom space below the base frame, the lifting and overturning mechanism can first lift the box. At this time, the negative pressure nozzle on the AGV car can be matched and inserted into the extension pipe. Then, the negative pressure mechanism provides negative pressure for the extension pipe, so that the cover at the end of the extension pipe also has negative pressure suction. By setting the cover at the port position of the storage space, when the AGV car lifts and moves the box, the floating raw materials can be adsorbed on the grid at the open part of the cover under the action of negative pressure suction, thereby reducing the possibility of raw materials floating to the surrounding environment, keeping the factory environment clean, improving the comfort of personnel work, and reducing the occurrence of personnel illness caused by bacterial growth.

[0010] Optionally, the overturning frame includes a bottom plate and a plurality of barrier wall mechanisms arranged at the side edges of the bottom plate. The barrier wall mechanism includes a main wall plate and a sliding plate, and the cover is embedded in the side wall of the main wall plate. The main wall plate has a hollow chamber inside, and the base frame is provided with a positive pressure mechanism for providing positive pressure to the inside of the hollow chamber.

[0011] The sliding plate is slidingly arranged inside the hollow chamber and abuts against the inner wall of the hollow chamber near the storage space. The side of the main wall plate near the storage space is provided with a plurality of first perforations in communication with the hollow chamber, and the sliding plate is provided with a plurality of second perforations. In the transfer state, each first perforation is arranged in a staggered manner with each second perforation, and in the unloading state, each first perforation is arranged in a directly opposite manner with each second perforation.

[0012] By adopting the above technical scheme, in the transfer state, the AGV car lifts and moves the box, and the positive pressure mechanism is in working state and continuously blows positive pressure air into the hollow chamber. However, at this time, the second perforations of the sliding plate are arranged in a staggered manner with the first perforations of the main wall plate, i.e. the sliding plate closes the first perforations to make it difficult for the positive pressure air to blow out from the first perforations, which is beneficial to the normal transfer of raw materials. When the AGV car carries the box to the feeding station, the AGV car drives the overturning frame to rotate around the hinge between the overturning frame and the base frame through the lifting and overturning mechanism. At this time, the sliding plate can be moved to a position where each second perforation is in communication with each first perforation, and the positive pressure air generated by the positive pressure mechanism can be blown into the storage space through the second perforation and the first perforation, so as to blow out the raw materials in the storage space during unloading, thereby improving the convenience of subsequent cleaning of the overturning frame.

[0013] Optionally, the positive pressure mechanism comprises a blower one fixed to the base frame and an arc-shaped hard pipe fixed to the outflow side of the blower one, the bottom of the main wall plate is provided with a clearance hole, the inner diameter of the clearance hole is larger than the outer diameter of the arc-shaped hard pipe, the arc-shaped hard pipe passes through the clearance hole and is partially located inside the hollow chamber, the side of the arc-shaped hard pipe away from the blower one is provided with a blocking ring, the outer diameter of the blocking ring is larger than the inner diameter of the clearance hole, and in the unloading state, the blocking ring abuts against the inner bottom wall of the hollow chamber and covers the clearance hole.

[0014] By adopting the above technical scheme, in the transfer state, the blower one of the positive pressure mechanism operates to blow positive pressure air into the arc-shaped hard pipe, and the positive pressure air is finally blown into the hollow chamber from the end of the arc-shaped hard pipe located inside the hollow chamber. Since the sliding plate blocks the first perforation at this time, and the outer diameter of the arc-shaped hard pipe is smaller than the inner diameter of the clearance hole, the positive pressure air inside the hollow chamber can be blown out through the clearance hole, so that the dust and foreign matter on the ground can be blown and cleaned when the AGV trolley moves, the stability of the AGV trolley moving is improved, and the possibility of the raw materials drifting away from the raw materials and scattering to the surrounding environment due to shaking is reduced.

[0015] In the unloading state, the lifting and overturning mechanism lifts and overturns the overturning frame upward, the blocking ring of the arc-shaped hard pipe can abut against the inner bottom wall of the hollow chamber and cover the clearance hole, and at this time, the sliding plate moves to make the first perforation communicate with the hollow chamber, so that the positive pressure air inside the hollow chamber can be blown into the storage space to smoothly blow out the raw materials, and the convenience of subsequent cleaning of the overturning frame is improved.

[0016] Optionally, the bottom of the base frame is provided with a mounting hole one for mounting the blower one, the hole diameter of the mounting hole one is matched with the hole diameter of the clearance hole, the inside of the mounting hole one is provided with a sleeve mechanism, the sleeve mechanism comprises a plurality of pipe barrel pieces which are sequentially movably sleeved, sliding limiting structures for limiting the mutual disengagement of the pipe barrel pieces are arranged between adjacent two pipe barrel pieces, each pipe barrel piece is provided with air-permeable mesh holes on the outer circumferential side, the innermost pipe barrel piece is connected to the inner wall of the mounting hole one through a connecting rod, and the blower one is fixed to the inside of the innermost pipe barrel piece.

[0017] By adopting the above technical scheme, the blower one is controlled to operate to blow positive pressure air into the hollow chamber, at this time, negative pressure is formed right below the blower one, and after the positive pressure air is blown out through the clearance hole and the mounting hole one, positive pressure is formed on the outside of the blower one, at this time, the foreign matter on the ground is easily rolled into the hollow chamber by the blower one when the AGV trolley transfers the box body. By arranging a plurality of pipe barrel pieces which are sequentially sleeved on the outside of the blower one, each pipe barrel piece can naturally sag under the action of gravity in the natural state, thereby playing a role in intercepting foreign matter and reducing the possibility of foreign matter entering the hollow chamber and being blocked inside the cover shell. The arrangement of the air-permeable mesh holes can keep the air on the inside and outside of the pipe barrel piece normally flowing.

[0018] Optionally, the sliding limiting structure comprises a sliding groove arranged on the outer wall of one pipe cylinder and a limiting block arranged on the inner wall of another adjacent pipe cylinder, the limiting block is inserted into the sliding groove and is arranged to slide in the sliding groove.

[0019] By adopting the above technical scheme, after the limiting block is inserted into the sliding groove, the adjacent pipe cylinders can be connected with each other, and the limiting block can move in the sliding groove, so that the adjacent pipe cylinders can be relatively displaced, and then the pipe cylinders can be unfolded in sequence.

[0020] Optionally, the positive pressure mechanism comprises a second air blower fixed to the base frame and a flexible connecting pipe connected to the air outlet side of the second air blower, and the end of the flexible connecting pipe away from the second air blower is communicated with the hollow chamber.

[0021] By adopting the above technical scheme, the arrangement of the flexible connecting pipe can ensure that the air outlet side of the second air blower is always communicated with the hollow chamber, so that the second air blower can deliver positive pressure air to the hollow chamber in the transfer state or the unloading state, and the positive pressure air can be smoothly blown into the storage space through the first perforation in the unloading state, so as to blow out the raw materials in the storage space.

[0022] Optionally, the bottom of the main wall plate is provided with a movable groove communicated with the hollow chamber, the bottom of the sliding plate is provided with a wedge-shaped extension, the wedge-shaped extension is arranged to pass through the movable groove and is movably arranged in the movable groove, the top of the base frame is provided with a positioning groove matched with the wedge-shaped extension, in the carrying state, the wedge-shaped extension is matched and arranged in the positioning groove, and the blocking wall mechanism further comprises an elastic member arranged between the sliding plate and the inner wall of the hollow chamber, in the unloading state, the elastic member forces the sliding plate to move and makes the first perforation and the second perforation be arranged opposite to each other.

[0023] By adopting the above technical scheme, when the wedge-shaped extension of the sliding plate is matched and arranged in the positioning groove of the base frame, the sliding plate can be kept at the position where the second perforation is misaligned with the first perforation, so as to seal the first perforation, when the turnover frame is lifted by the lifting and overturning mechanism and is turned upward, the wedge-shaped extension gradually separates from the positioning groove, at this time, the elastic force of the elastic member can drive the sliding plate to move outward, and finally the sliding plate moves to the position where the second perforation is opposite to the first perforation, so that the positive pressure air can smoothly blow out the raw materials in the storage space.

[0024] Optionally, the outer side of the main wall plate is fixed with a mounting seat, the mounting seat is provided with a lead screw and a rotary driving member for driving the lead screw to rotate, a threaded segment of the lead screw is threadedly connected with a sliding seat, the side of the sliding seat close to the main wall plate is fixed with a jacking rod, and the jacking rod passes through the main wall plate and abuts against the side of the sliding plate away from the elastic member.

[0025] By adopting the technical scheme, in the unloading state, after the raw materials in the storage space gradually pour out, the rotation of the rotating driving part is controlled to drive the rotation of the lead screw, the sliding seat on the lead screw can gradually move towards the sliding plate, and finally the ejector rod can abut against the sliding plate and push the sliding plate to move inward to extrude the elastic member, which can adjust the width of the area where the first perforation and the second perforation are opposite, thereby increasing the wind pressure blown out of the first perforation, and better blowing the raw materials out of the storage space, further reducing the possibility of raw materials remaining in the storage space.

[0026] Optionally, the bottom space is internally provided with a connection socket for controlling the start and stop of the positive pressure mechanism, and the AGV trolley is provided with a connection plug matched with the connection socket, in the transfer state, the connection plug is inserted into the connection socket and electrically connected to the connection socket.

[0027] By adopting the technical scheme, in the transfer state, the lifting and overturning mechanism lifts up and lifts the box body, at this time the connection plug of the AGV trolley can be inserted into the connection socket of the base frame, so that the positive pressure mechanism is powered on and normally operates, which is convenient to use; and in the case that the box body is not used, the positive pressure mechanism is in a non-powered stop state, which can reduce energy consumption and is beneficial to maintaining good service life of the positive pressure mechanism.

[0028] Optionally, the outer diameter of the negative pressure insertion tube is smaller than the inner diameter of the extension pipe; the outer periphery of the negative pressure insertion tube is bonded with a sealing felt ring, and in the transfer state, the sealing felt ring is matched and abuts against the inner peripheral wall of the extension pipe.
