Referring to fig. 1 and 2, the brick transferring device for a brick paving machine comprises a brick clamping mechanism 500 and a grabbing trigger switch 600, wherein in the clamping and transferring process of a single row of brick groups 800 on a material table 700, the grabbing trigger switch 600 can be utilized to trigger the clamping action, and the false triggering problem of the grabbing trigger switch 600 in the transferring process of the clamping mechanism 500 can be avoided.
The brick clamping mechanism 500 comprises a first horizontal moving mechanism 501, two groups of vertical moving mechanisms 502, two groups of second horizontal moving mechanisms 503 and two clamping grippers 504; wherein the first horizontal moving mechanism 501 is horizontally spanned above the material table 700 and the first brick conveying belt 900 by a supporting beam fixed on the movable chassis; the two groups of vertical moving mechanisms 502 are symmetrically arranged in the conveying direction of the first brick conveying belt 900, and the top ends of the two groups of vertical moving mechanisms are respectively fixed at two sides of the bottom of the moving slide block of the first horizontal moving mechanism 501, so that the two groups of vertical moving mechanisms 502 can horizontally and synchronously move from the upper part of the first brick conveying belt 900 to the upper part of the material table 700; a connecting beam 505 is horizontally connected and fixed between the movable sliders of the two groups of vertical moving mechanisms 502, and the two groups of second horizontal moving mechanisms 503 are symmetrically fixed at the bottom of the connecting beam 505, so that the two groups of second horizontal moving mechanisms 503 can synchronously lift and lower in the vertical direction through the two groups of vertical moving mechanisms 502; the two clamping claws 504 are two vertical plates which are symmetrically arranged in a parallel mode and are respectively fixed on the bottom surfaces of the movable sliding blocks of the two groups of second horizontal moving mechanisms 503, so that the distance between the two clamping claws 504 can be adjusted by controlling the movable blocks on the two groups of second horizontal moving mechanisms 503 to synchronously move in opposite directions or synchronously move in opposite directions.
In this embodiment, the first horizontal moving mechanism 501, the vertical moving mechanism 502, and the second horizontal moving mechanism 503 may be assembled by using the existing devices with corresponding action functions, such as an electric control moving sliding table; as another implementation of the present embodiment, the second horizontal movement mechanism 503 and the two gripping grippers 504 may be replaced by parallel mechanical gripping jaws.
The brick clamping mechanism 500 further comprises a controller, which is respectively connected with the first horizontal moving mechanism 501, the vertical moving mechanism 502 and the second horizontal moving mechanism 503, so as to control the brick clamping mechanism 500 to grab and transport the multi-row brick groups 800 piled on the material table 700 one by one; specifically, since the table top height of the material table 700 is fixed, and the plurality of rows of brick groups on the material table 700 can be arranged along the conveying direction of the first brick conveying belt 900, that is, the height of each layer of bricks can be determined, but the distance between each layer of bricks and the brick clamping mechanism 500 is not determined; therefore, the brick clamping mechanism 500 can firstly adjust the vertical movement distance of the moving slide blocks on the vertical movement mechanism 502 through the controller in the vertical direction, and the horizontal movement distance of the moving slide blocks on the first horizontal movement mechanism 501 in the horizontal direction needs to be achieved through the grabbing trigger switch 600, that is, the grabbing trigger switch 600 is utilized to detect that the brick clamping mechanism 500 arrives at the single row of brick groups 800 and send grabbing signals, at this time, the controller controls the moving slide blocks on the first horizontal movement mechanism 501 to stop moving, and simultaneously controls the moving slide blocks on the two second horizontal movement mechanisms 503 to synchronously move towards each other, so that the two clamping grippers 504 clamp the side walls of the two end side bricks of the single row of brick groups, thereby achieving the integral clamping of the single row of brick groups 800; the controller controls the moving slide blocks on the first horizontal moving mechanism 501 to reversely move to the position above the first brick conveying belt 900, so that the clamped single-row brick groups 800 are lowered onto the first brick conveying belt 900 by controlling the moving slide blocks of the vertical moving mechanisms 502 to descend and controlling the moving slide blocks on the two second horizontal moving mechanisms 503 to synchronously reversely move, and then the conveying of the single-row brick groups from the material table 700 side to the first brick conveying belt 900 side is completed; by analogy, the brick clamping mechanism 500 finally completes transferring of the multi-layered single-row brick groups 800 stacked on the material table according to the sequence from top to bottom and the sequence from the near to the far of the single-row brick groups 800 of each layer.
Referring to fig. 5, the grip trigger switch 600 includes a switching device body and a trigger mechanism; the switch device body includes a limit switch 104 disposed in the protective housing 100, where a contact of the limit switch 104 extends out of the protective housing 100 through a window formed on the protective housing 100, so that the contact of the limit switch 104 is collided by a trigger mechanism, so that the limit switch 104 emits a grabbing signal to a controller connected with the limit switch 104, and the controller executes the grabbing and transferring actions on the single row brick group 800 based on the grabbing signal.
The triggering mechanism comprises a base bracket 300 and a triggering bracket which are connected from top to bottom; wherein,
The base bracket 300 is a vertically arranged bracket body, on which the mounting block 200 is fixed, and the mounting block 200 is provided with a through hole which is perpendicular to the protective housing 100 and is internally provided with a bearing along the horizontal direction; correspondingly, a connecting shaft 103 is vertically fixed on the protective housing 100 below the window, and penetrates through and is fixed in the bearing center hole of the mounting block 200, so that the base bracket 300 is rotationally connected to the switchgear body, namely, the base bracket 300 is rotated clockwise or counterclockwise around the connecting shaft 103; the setting position of the base bracket 300 on the switchgear body is adapted to the setting position of the limit switch 104 on the switchgear body, so that when the base bracket 300 rotates anticlockwise, the top end of the base bracket collides with the contact of the limit switch 104 and emits a grabbing signal, and when the base bracket 300 rotates clockwise, the limit switch 104 is not triggered.
As a preferable technical solution of this embodiment, a vertical mounting through hole 302 is formed in the base bracket 300 along the length direction thereof, so that the mounting block 200 can be fixed at any position in the length direction of the base bracket 300, thereby realizing adjustment of the length of the base bracket 300 extending below the protective housing 100. In this embodiment, a strip-shaped mounting through hole 302 is formed in the base bracket 300 along the length direction thereof; the mounting block 200 is composed of two fixing plates which are arranged in parallel and symmetrically arranged at the front side and the rear side of the base bracket 300, the upper sides of the two fixing plates are provided with mounting through holes for assembling bearings, the lower sides of the two fixing plates are provided with screw holes for arranging bolts, so that the two fixing plates are clamped and fixed at the front side and the rear side of the base bracket 300 through the bolts so as to be connected and fixed with the base bracket 300 into a whole; the mounting block 200 is matched with the mounting through hole 302, so that the fixing position of the mounting block 200 on the base bracket 300 can be adjusted, and meanwhile, the mounting difficulty is reduced, and the adjustment is convenient.
The protection plate 101 and the limit switch 104 are respectively arranged at two sides of the top end of the base bracket 300 to limit the base bracket 300 to rotate towards the side not provided with the limit switch 104; in this embodiment, since the contact of the limit switch 104 is disposed on the left side of the base bracket 300, the counterclockwise rotation of the base bracket 300 around the rotation shaft 103 belongs to the switch triggering action, that is, the counterclockwise rotation direction of the base bracket 300 is the triggering direction; conversely, the clockwise rotation of the base bracket 300 around the rotation shaft 103 belongs to the false triggering action of the switch, that is, the clockwise rotation direction of the base bracket 300 is the false triggering direction; therefore, in order to limit the false triggering operation, the shielding plate 101 is provided on the outer wall of the shielding case 100 located at the right side of the base bracket 300; specifically, the protection plate 101 is vertically disposed on the adjacent side of the base support 300 and is vertically fixed on the outer wall of the protection casing, so that when the base support 300 rotates clockwise around the rotation shaft 103 due to an external force, the protection plate 101 limits the base support 300, and the base support 300 is prevented from rotating in a false triggering direction due to the external force.
The grab trigger switch 600 further includes a reset mechanism including a tension spring 102 and a fixed block 105; specifically, the fixing block 105 is fixed on the right protection housing 100 of the base bracket 300 and is spaced apart from the base bracket 300; the front end surface of the fixing block 105 is preferably flush with the front end surface of the base bracket 300, and both ends of the tension spring 102 are fixed to the front end surfaces of the base bracket 300 and the fixing block 105, respectively. In the initial state, the tension spring 102 is arranged in a free state; in practical application, when the base bracket 300 rotates anticlockwise to trigger the limit switch 104, the tension spring 102 stretches synchronously; further, after the swing is completed, the base bracket 300 can be rotated clockwise in synchronization with the restoration of the initial state of the tension spring 102, and reset to the initial vertical state, so as to wait for the next trigger action to be performed.
The trigger bracket is arranged below the base bracket 300, and the top end of the trigger bracket is rotatably connected to the bottom end of the base bracket 300, so that the trigger bracket can rotate clockwise or anticlockwise relative to the base bracket 300; a synchronizing plate 301 capable of limiting the trigger bracket to rotate clockwise is arranged at the rotation connection part of the trigger bracket and the base bracket 300, so that the trigger bracket can only rotate clockwise relative to the base bracket 300 in practice; the clockwise rotation direction of the trigger support is the false trigger action direction, and the anticlockwise rotation direction of the trigger support is the trigger action direction.
In this embodiment, the synchronization plate 301 is composed of two vertical plates connected vertically, one vertical plate is fixed on the back side of the bottom end of the base bracket 300, and the other vertical plate is limited on the right side of the top end of the trigger bracket, so that when the trigger bracket rotates anticlockwise, the top end of the trigger bracket can not rotate due to abutting against the limited vertical plate; the arrangement of the synchronization plate 301 does not affect the rotational arrangement relationship between the trigger mount and the base mount 300. Based on this, in practical application, when the bottom end of the trigger support is subjected to an external force to rotate clockwise, the base support 300 does not rotate; when the bottom end of the trigger support is subject to the external force and is about to rotate counterclockwise, the trigger support can only rotate counterclockwise with the base support 300 by utilizing the rotation setting relationship between the base support 300 and the protection housing 100 under the limit action of the synchronizing plate 301, i.e. perform a trigger action.

Preferably, the triggering portion 404 includes two rollers symmetrically disposed at two sides of the bottom end of the movable frame 402, and can freely roll in the swinging direction of the movable frame 402, so as to realize sliding contact with objects such as the brick 500, thereby improving the structural flexibility of the triggering bracket and reducing false triggering.
In the present embodiment, the fixing frame 401 is constituted by an upper connection plate and a lower connection plate; the upper connecting plate is a right angle plate and is formed by connecting a vertical plate with a transverse plate vertically fixed at the bottom end of the vertical plate; wherein, the vertical plate of the upper connecting plate is parallel to one vertical plate of the synchronizing plate 301 and is respectively provided with a front side and a rear side of the foundation bracket 300, the vertical plate of the upper connecting plate is vertically provided with a through hole with a built-in bearing along the horizontal direction, a rotating shaft is penetrated and fixed in the shaft sleeve, the rear end of the rotating shaft is vertically penetrated and fixed on the vertical plate through the strip-shaped mounting through hole 302, so that the fixing frame 401 is rotationally connected with the foundation bracket 300; the lower connecting plate is a vertical plate, the movable frame 402 is formed by integrally connecting the vertical plate and the inclined plate from top to bottom, and the length of the movable frame is longer than that of the lower connecting plate; the vertical plates and the lower connecting plates of the movable frame 402 are arranged in parallel and symmetrically arranged at the left side and the right side of the bottom surface of the transverse plate of the upper connecting plate, wherein a hinge 405 is arranged on the top surface of the left side of the transverse plate, one end of the hinge 405 is horizontally fixed on the transverse plate through a screw, and the other end of the hinge 405 is fixed on the top plate wall of the vertical plate of the movable frame 402, so that the vertical plate of the movable frame 402 is hinged on the transverse plate through the hinge 405 and can swing left and right relative to the fixed frame 401; a bar-shaped through hole is formed in the vertical direction on a vertical plate of the movable frame 402, and a screw hole is formed in the lower connecting plate; the adjusting rod 403 is a cylindrical rod body, external threads are machined on the rod walls at two ends of the adjusting rod, and a limit cap is arranged at one end of the rod body; one end of the adjusting rod 403 provided with a limiting cap is vertically penetrated and fixed in a screw hole of the lower connecting plate in a threaded manner, the other end of the adjusting rod 403 is penetrated and arranged in a strip-shaped through hole on the movable frame 402, and the movable frame 402 is movably limited on the adjusting rod 403 through two limiting blocks 406 sleeved on the end side of the adjusting rod 403 and positioned on two sides of the movable frame 402; the swing range of the limiting movable frame 402 is adjustable by adjusting the positions and the intervals of the two limiting blocks 406 on the adjusting rod 403, so that the flexibility of the trigger support structure is improved, and the sensitivity of the trigger part 404 to trigger action is adjusted; the inclined plate of the movable frame 402 and the vertical plate thereof form an obtuse angle, and the inclined plate is arranged in a manner of inclining to trigger the outer side of the bracket (namely the left side of the vertical plate of the movable frame 402); the distance between the bottom end of the triggering portion 404 and the clamping claw 504 is adapted to the size of the brick, so that when the triggering portion 404 abuts against the side wall of the brick, the clamping claw 504 should be centrally disposed at two end sides of the single row of brick group 800, so as to ensure the clamping stability.
Referring to fig. 1, the grabbing trigger switch 600 is fixed to the brick clamping mechanism 500 through a switch device body, specifically, fixed to a side of a connecting beam 505 of the brick clamping mechanism 500, which is far from the material table 700; in the process that the grabbing trigger switch 600 synchronously approaches the material table 700 along with the brick clamping mechanism 500, the trigger part 404 is abutted against the single-row brick group 800 to trigger the grabbing trigger switch 600 to send a grabbing signal to the controller, so that the controller is used for controlling the brick clamping mechanism 500 to stop and grab the single-row brick group 800, and then the single-row brick group is conveyed onto the first brick conveying belt 900.
In practical application, the grabbing trigger switch 600 may perform the action of triggering the limit switch, or may perform the action of avoiding false triggering of the limit switch, so as to effectively ensure the safety of the trigger mechanism, specifically:
Referring to fig. 5, in the process that the grabbing trigger switch 600 moves along with the brick clamping mechanism 500 to the material platform 700, when the trigger part 404 abuts against the side wall of the single row of brick groups 800 and continues to move along with the brick clamping mechanism 500, the single row of brick groups 800 push the trigger part 404 to drive the trigger bracket to rotate anticlockwise, at this time, because the synchronous plate 301 is limited at the rotation connection position of the trigger bracket and the base bracket 300, the trigger bracket synchronously drives the base bracket 300 to rotate anticlockwise until the base bracket 300 collides with the contact of the limit switch 104; the limit switch 104 sends a grabbing signal to the controller, the controller randomly controls the brick clamping mechanism 500 to stop moving and controls the two clamping jaws to move oppositely to clamp two ends of the single-row brick group 800, and then the controller controls the brick clamping mechanism 500 to move reversely to the position above the first brick conveyer belt 900 and lowers the single-row brick group 800; in the process of reversely moving the brick clamping mechanism 500, the foundation bracket 300 drives the trigger bracket to restore to the initial vertical setting state under the action of the tension spring 102, and reduces the reset swing condition of the foundation bracket 300 under the limit action of the protection plate 101;
Referring to fig. 6, in the process of moving the grabbing trigger switch 600 along with the brick clamping mechanism 500 to the first brick conveyor 900 or in the process of lowering the single-row brick group 800, when the trigger portion 404 abuts against the top surface of a brick or the top side of another object (such as a conveyor belt), the trigger portion 404 will drive the trigger bracket to rotate clockwise, at this time, since the trigger bracket is rotationally connected with the base bracket 300, the base bracket 300 does not rotate synchronously with the trigger bracket, and still keeps a vertical setting state, so as to effectively avoid the occurrence of false triggering rotation action of the base bracket 300, and also prevent the occurrence of damage of the limit switch due to false triggering action.
The above is only a preferred embodiment of the present invention, and the technical solution for achieving the object of the present invention by substantially the same means is within the scope of the present invention.
