The whole switching process is time-consuming and labor-consuming and can greatly affect the working efficiency of the barrel conveyor.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and provides a stepping type barrel bidirectional conveyor which can realize bidirectional conveying of barrels fully automatically and greatly improve the working efficiency.

The invention aims at realizing the following technical scheme:

the stepping barrel bidirectional conveyor comprises a conveying platform, a driving platform, a linear driving mechanism, a pull rod and a push hook, wherein the conveying platform and the driving platform are connected end to end, the linear driving mechanism is arranged on the driving platform, the pull rod is connected with the output end of the linear driving mechanism and extends into the conveying platform, the pull rod is provided with a first pull rod and a second pull rod, the push hook is provided with two adjacent push edges, and a rotary shaft is connected between one end, connected with the center of the push hook and the two push edges, of the push hook and the two pull rods respectively; the two pull rods are respectively connected with a first movable bracket and a second movable bracket at the driving platform, and a dislocation driving mechanism for enabling the two pull rods to move relatively in the length direction is arranged between the two movable brackets; the output end of the linear driving mechanism is connected with one of the movable brackets.

The working principle of the invention is as follows: firstly, it should be noted that, the push hook capable of realizing bidirectional switching generally adopts an isosceles triangle push hook as disclosed in the background art, and the two isosceles sides of the isosceles triangle can be oriented to opposite sides in a vertical state through rotation of the isosceles triangle at the same angle, namely, the push hook orientation is switched, so that the push hook is not exceptional in the invention.

Specifically, the two pull rods are relatively moved in the length direction through the dislocation driving mechanism, so that the rotary shaft at the center of the push hook is used as the axis, the rotary shaft at the end part toggles the push hook to rotate around the center of the push hook, and the push hook is respectively switched to a state that the first push edge is vertical, the bottom edges connecting the two push edges are upward and the second push edge is vertical according to the required conveying direction and conveying action. For example, the first pushing edge is in a vertical state and props against the inner side wall of the barrel, and the linear driving mechanism drives the pull rod and the pushing hook to move so as to pull the barrel to move; then the bottom edge is switched to be in an upward horizontal state, and then the linear driving mechanism drives the pull rod and the pushing hooks to return, namely all the pushing hooks are moved to the lower part of the next barrel, and then the first pushing edge is made to be vertical, and the barrel is pulled to move again. If the reverse conveying is required, the second pushing edge is switched between the vertical state and the bottom edge is in the horizontal state according to the actions.

It is also to be noted that, because the dislocation driving mechanism is arranged between the two moving brackets, and the two moving brackets are respectively connected with the two pull rods, namely, the two pull rods are always connected with each other, the linear driving mechanism only needs to pull one of the moving brackets, and can simultaneously pull the two pull rods to synchronously move, so that the state of pushing the hook is not influenced.

Preferably, the dislocation driving mechanism comprises a first motor arranged on a first movable bracket, an eccentric wheel arranged at the output end of the first motor and an eccentric wheel pushing groove arranged on a second movable bracket; the eccentric wheel extends into the eccentric wheel pushing groove. The dislocation driving mechanism is simple, stable and efficient in action, and realizes the relative movement of the two movable brackets and the two pull rods by utilizing the reciprocating displacement generated when the eccentric wheel rotates to match with the eccentric wheel pushing groove, so that the state switching of pushing hooks is realized.

As the invention is preferable, the side surface of the eccentric wheel pushing groove facing the axial end surface of the eccentric wheel is provided with two redirecting proximity switches and one avoiding proximity switch, and the axial end surface of the eccentric wheel is provided with a trigger piece so as to automatically and accurately control the action range of the eccentric wheel and ensure the accurate control of the three states of the pushing hook.

Preferably, the trigger piece is a bolt with the head size matched with the redirecting proximity switch and the avoiding proximity switch, so that the trigger piece is convenient to install on one hand, and the positioning accuracy is ensured on the other hand.

As the invention is preferable, the push hook is arranged at the joint of the two push edges, and the two pull rods are provided with the mounting grooves matched with the rotating shafts, and the mounting sequence of each part of the whole conveying platform is higher if the rotating shafts are inserted from the side surface because the width of the whole conveying platform is larger; the structure of the mounting groove simplifies the mounting process, and the rotating shaft can be placed from the upper side surface and the lower side surface of the conveying platform, and then the opening of the mounting groove is closed.

As the invention, the circumference of the eccentric wheel is provided with the bearing so as to avoid jamming and improve the fluency of the rotation of the eccentric wheel relative to the pushing groove of the eccentric wheel, thereby improving the positioning accuracy.

Preferably, the linear driving mechanism comprises a linear bracket, two chain wheels and chains arranged on the side surface of the linear bracket, and a second motor in transmission connection with the chain wheels far away from the conveying platform; the chain is connected with the second movable bracket. The chain wheel and the chain are driven to rotate by the second motor, the chain pulls the second movable support, the second movable support drives the first movable support, and the two movable supports synchronously drive the two pull rods and the push hook to move so as to realize the linear movement of the push hook; meanwhile, reverse conveying can be performed only by reversing the second motor.

As the invention is preferable, limit proximity switches are arranged at the front end and the rear end of the linear support, and a proximity trigger plate is arranged on the second movable support so as to control the movement range and ensure the stable operation of the equipment.

Preferably, in the present invention, a micro switch is disposed on the linear support at an end near the second motor, and a micro trigger plate is disposed on the second movable support, and since the second motor is disposed at the end, the movable support is further ensured to be stably stopped at the end by the micro switch.

In addition, in order to avoid interference between the slider 16 and the push hook 71 caused by back and forth movement of the slider 16 along the pull rods, the slider 16 is fixedly connected with the first pull rod 51 through screws, so that the relative movement of the two pull rods is not affected. A lower liner 15 is provided between the side members 13 and the slide 16 and the bottom plate 11, and an upper platen 14 is provided above the slide 16, the side members 13 and the support flap 12. The supporting strip 17 is arranged on the upper side of the supporting flap 12 for reducing the friction resistance between the strip drum 4 and the conveying platform 1.

The driving platform 2 mainly comprises a bottom plate, a linear bracket 21, a wire slot plate 22 and a drag chain slot plate 23; the bottom plate is consistent with the bottom plate of the conveying platform 1, the linear bracket 21 is arranged in the middle of the bottom plate, and the wire slot plate 22 and the drag chain slot plate 23 are respectively arranged on two sides of the bottom plate and used for arranging cables and drag chains. The linear support 21 is provided with two guide rails 24, the two guide rails 24 are respectively provided with a first movable support 25 and a second movable support 26 through sliding blocks, and the two movable supports are respectively connected with a first pull rod 51 and a second pull rod 52 through strip-shaped notches formed in the upper side face of the linear support 21 along the conveying direction. Because the length of the pull rod is longer, in order to facilitate production and installation, the pull rod improves the moving fluency simultaneously, and the pull rod adopts a multistage structure, and adjacent sections of pull rods are rotationally connected through chain links 53.

The first moving bracket 25 is provided with a first motor 61, the output end of the first motor 61 faces the second moving bracket 26, the output end of the first motor is provided with an eccentric wheel 62, the eccentric wheel 62 is circumferentially provided with a bearing, the second moving bracket 26 is surrounded by a plate body to form an eccentric wheel pushing groove 63 facing the first moving bracket 25, and the eccentric wheel 62 extends into the eccentric wheel pushing groove 63; and the diameter of the eccentric 62 is equal to the width of the eccentric pushing groove 63 to ensure stability of the motion. Meanwhile, the parts of the first pull rod 51 and the second pull rod 52, which are positioned on the conveying platform 1, are provided with a plurality of pushing hooks 71 distributed along the conveying direction, and the distance between the adjacent pushing hooks 71 is matched with the diameter of the barrel 4; the pushing hook 71 is in the shape of an isosceles triangle, two isosceles sides are pushing sides, a first rotating shaft 72 is arranged between the center of the pushing hook and the first pull rod 51, a second rotating shaft 73 is arranged between the connecting ends of the two isosceles sides and the second pull rod 52, and of course, in order to adapt to the height change of the connecting ends of the two isosceles sides when the pushing hook rotates around the center, the holes of the pushing hook 71 and/or the second pull rod 52, which are provided with the rotating shafts, are bar-shaped holes or grooves. In this way, the reciprocating displacement generated when the eccentric wheel 62 rotates is utilized to cooperate with the eccentric wheel pushing groove 63 to realize the relative movement of the two moving brackets and the two pull rods, so that the pushing hook 71 is driven by the second rotating shaft 73 to rotate around the center of the pushing hook by taking the first rotating shaft 72 as the axis, and the pushing hook is respectively switched to the three states of pushing the barrel towards the first side, resetting the pushing hook and pushing the barrel towards the second side according to the required conveying direction and conveying action when the first pushing edge 711 is in the vertical state, the bottom edge 712 is in the upward horizontal state and the second pushing edge 713 is in the vertical state.

Two chain wheels 81 and a chain 82 along the conveying direction are arranged on the side surface, close to the second movable support 26, of the linear support 21, a second motor 83 is arranged on one side, far away from the conveying platform 1, of the driving platform 2, the output end of the second motor 83 is in transmission connection with the chain wheel at the end, and the chain 82 is connected with the second movable support 26. That is, the second moving bracket 26 is driven to linearly move along the guide rail 24 by the rotation of the chain 82, and the second moving bracket 26 and the first moving bracket 25 keep synchronously moving by the matching relationship of the eccentric wheel 62 and the eccentric wheel pushing groove 63, so that the two pull rods respectively connected with the two moving brackets keep synchronously moving, and finally the push hook 71 is driven to keep moving in a switched state.

In summary, the working principle of the bidirectional conveyor is as follows: first, the first barrel 4 is placed on one end of the conveying platform 1 by other conveying devices, the push hook 71 may be just under the barrel 4 in advance, or the push hook 71 may be in a state that the bottom edge 712 is upward, and may be moved under the barrel 4 under the driving of the second motor 83. The pushing hook 71 is then driven by the first motor 61 to switch to the first pushing edge 711 in the vertical state, i.e. the pushing hook 71 extends into the groove at the lower end of the barrel 4. The push hook 71 is then moved by the second motor 83, the push hook 71 pushing the barrel 4 a distance of one stroke, the length of one stroke being related to the length of the chain 82. Then, the pushing hook 71 is in a state that the bottom edge 712 is upward, and the pushing hook 71 returns to a stroke distance, and a second barrel is placed at one end on the conveying platform 1; then, the pushing hooks 71 are switched to a state that the first pushing edge 711 is vertical, and at the moment, pushing hooks 71 are arranged at the bottoms of two cans on the conveying platform, and a stroke is conveyed again; the circulation can realize the barrel conveying in one direction. If the barrel is to be reversely conveyed, the push hook 71 is only required to be switched between the second push edge 713 in the vertical state and the bottom edge 712 in the upward state, and the linear conveying mechanism is matched, which is not described herein.

Specifically, in order to precisely control the state switching action of the push hook 71, two redirecting proximity switches 64 and one avoiding proximity switch 65 are disposed on the side surface of the eccentric wheel pushing groove 63 facing the axial end surface of the eccentric wheel 62, and a trigger piece 66 is disposed on the axial end surface of the eccentric wheel 62, that is, three position states of the push hook 71 are positioned by cooperation of the trigger piece 66 and the three proximity switches. Further, in order to make the position control simpler and more accurate, the two redirecting proximity switches 64 respectively correspond to the positions when the eccentric wheel 62 reaches the maximum distance in the left-right directions, and because the pushing hooks 71 are symmetrical structures, the avoiding proximity switch 65 can only be located above or below the middle of the two redirecting proximity switches 64, at this time, the two redirecting proximity switches 64 are both 90 ° away from the avoiding proximity switch, that is, the pushing hooks 71 are isosceles right triangles. The trigger member 66 is preferably a bolt with a head size adapted to the redirecting proximity switch 64 and the avoiding proximity switch 65, which is convenient for installation on the one hand and ensures positioning accuracy on the other hand.

In order to precisely control the movement stroke of the push hook 71, limit proximity switches 84 are disposed on the front and rear ends of the linear bracket 21, and a proximity trigger plate 85 is disposed on the second movable bracket 26. The linear support 21 is provided with a micro switch 86 at one end close to the second motor 83, and the second movable support 26 is provided with a micro trigger plate 87, and since the second motor is provided at the one end, the micro switch further ensures that the movable support can stop stably at the one end, and collision with the second motor is avoided.

In addition, in order to simplify the installation process of the conveying platform 1, the push hook 71 is arranged at the joint of the two push edges, and the two pull rods are provided with installation grooves matched with the rotating shafts, so that the installation sequence of each part of the whole conveying platform has higher requirements if the rotating shafts are inserted from the side surface due to the larger width of the whole conveying platform 1; the structure of the above-mentioned mounting groove simplifies the mounting process, i.e. the rotating shafts can be placed from the upper and lower sides of the conveying platform, for example, one rotating shaft is inserted into the central hole of the push hook 71, then the rotating shaft is aligned with the mounting groove on the first pull rod 51, the push hook 71 is placed between the two pull rods, the angle of the push hook 71 is adjusted, the mounting grooves on the push hook 71 and the second pull rod 52 are aligned, then the other rotating shaft is placed from the lower side, and finally the opening of the mounting groove is closed by using the lower lining plate 15 and the upper pressing plate 14.

The foregoing is merely a preferred embodiment of the present invention, which is based on one implementation of the overall concept of the present invention, and the scope of the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the technical scope of the present invention should be covered by the scope of the present invention.
