[0002] Commonly used in non-load-bearing parts, the hole rate is not less than 40%, the size of the empty is large and the number is small. The brick is called hollow brick, and the hollow brick is divided into cement hollow brick, clay hollow brick and shale hollow brick. After the production process of hollow brick, it needs to be transferred to baking or clamped and stacked, etc. After the production of hollow brick, the hole is generally vertical, and when clamping with a mechanical hand, it is often necessary to turn the blank to make the inner hole horizontal, so as to facilitate clamping.

[0007] Preferably, a stabilizing shaft is slidably connected to the upper left corner of the inner side of the frame and located outside the egg-shaped track groove, and a rubber sleeve is fitted on the surface of the stabilizing shaft.

[0013] Beneficial effects

[0014] This invention provides an automated turning structure for hollow brick production. Compared with the prior art, it has the following advantages:

[0015] (1) The automated brick-turning structure for hollow brick production uses a cross-shaped flip plate. When rotating, the brick blank on the right flip plate can be flipped to the left and made upright, which facilitates the subsequent gripping and removal of the brick blank by the robot arm. By setting the flip plate as a telescopic structure and using an egg-shaped track groove in conjunction with rollers, the flip plate can automatically complete the extension and retraction during rotation. When the flip plate is on the right side, the extension is the largest, which can completely support the brick blank and ensure that the brick blank will not fall off during the flipping process. When it is upright, it retracts, which exposes the top of the brick blank, so that the flip plate will not obstruct the gripping of the robot arm. The automated operation saves manpower.

[0016] (2) The automated turning structure for hollow brick production has a stabilizing shaft set elastically in the upper left corner. When the brick blank is turned to the left and stood upright, the stabilizing shaft can press on the surface of the brick blank to stabilize it, preventing it from tipping over due to inertia. The stabilizing shaft can also slide elastically, thus adapting to brick blanks of different thicknesses and improving versatility and self-adaptability.

[0017] (3) The automated turning structure for hollow brick production, by setting an intermittent linkage mechanism to link the conveying mechanism and the turning mechanism, can use the rotational power of the conveying mechanism to intermittently drive the turning mechanism to perform the turning operation, making the equipment operation more continuous, saving the need to use and control an additional set of motor drive structure, thus saving costs.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides three technical solutions:

[0026] Figures 1-3 The first embodiment is shown: an automated turning structure for hollow brick production, including a conveying mechanism 1 and a turning mechanism 2 connected to its left side. The turning mechanism 2 turns the hollow brick blanks conveyed by the conveying mechanism to stand upright. The turning mechanism 2 includes a frame 21 and a turntable 22 rotatably connected to its front and rear inner surfaces. Four sets of mutually perpendicular turning plates 23 are fixedly connected between the two turntables 22. Support sleeves 24 are fixedly connected to the left and right sides of the inner side of the frame 21.

[0027] The flip plate 23 includes a sleeve plate 231 fixedly connected to the turntable 22, and a slide plate 232 is slidably connected inside the sleeve plate 231. A stop bar 233 is fixedly connected to one end of the slide plate 232 outside the sleeve plate 231, and rollers 234 are rotatably connected to both ends of the stop bar 233. A support rib 235 flush with the outer surface of the sleeve plate 231 is fixedly connected to one side of the slide plate 232, and a groove 236 adapted to the support rib 235 is opened on this side of the sleeve plate 231. Egg-shaped track grooves 25 are stamped outward on both the front and rear sides of the frame 21, and the rollers 234 are rotatably connected to the inner surface of the egg-shaped track groove 25. The egg-shaped track groove 25 is composed of a semi-circular left half and an elliptical right half, so that the slide plate 232 extends out of the sleeve plate 231 when it is in the right half and retracts into the sleeve plate 231 when it is in the left half.

[0028] By setting the flip plate 23 in a cross layout, the brick blank on the right flip plate 23 can be flipped to the left and made upright when rotating, which facilitates the subsequent gripping and removal of the brick blank by the robot arm. By setting the flip plate 23 as a telescopic structure and using the egg-shaped track groove 25 in conjunction with the roller 234, the flip plate 23 can automatically complete the extension and retraction during rotation. When the flip plate 23 is on the right side, the extension is the largest, which can completely support the brick blank and ensure that the brick blank will not fall off during the flipping process. When it is upright, it retracts, which exposes the top of the brick blank, so that the flip plate 23 will not obstruct the gripping of the robot arm. The automated operation saves manpower.

[0029] Figures 1-2The second embodiment is shown. The main difference from the first embodiment is that a stabilizing shaft 26 is slidably connected to the upper left corner of the inner side of the frame 21 and outside the egg-shaped track groove 25. The surface of the stabilizing shaft 26 is covered with a rubber sleeve. Both ends of the stabilizing shaft 26 extend to the outside of the frame 21. Limiting grooves 27 adapted to the stabilizing shaft 26 are opened on both the front and rear sides of the frame 21. An elastic band 28 is sleeved between the outer side of the frame 21 and the end of the stabilizing shaft 26, located on the right side of the limiting groove 27.

[0030] By elastically setting a stabilizing shaft 26 in the upper left corner, when the brick blank is flipped to the left and stood upright, the stabilizing shaft 26 can press against the surface of the brick blank to stabilize it, preventing it from tipping over due to inertia. Furthermore, the stabilizing shaft 26 can slide elastically, thus adapting to brick blanks of different thicknesses and improving versatility and self-adaptability.

[0031] Figures 1-2 Figures 4-5 show the third embodiment, which differs from the second embodiment in that: the conveying mechanism 1 includes a conveying frame 11 and a transmission roller 12 rotatably connected to both ends inside it, and a conveyor belt 13 is connected between the two transmission rollers 12. Several support rollers 14 are rotatably connected to the bottom surface of the inner side of the conveying frame 11 and the upper half of the conveyor belt 13. A positioning sleeve 29 is fixedly connected to the right side of the inner side of the frame 21, and a positioning block 15 that engages with the positioning sleeve 29 is fixedly connected to the left side of the inner side of the conveying frame 11. The positioning sleeve 29, the positioning block 15 and the top of the right-side flip plate 23 are flush. By setting the cooperation between the positioning sleeve 29 and the positioning block 15, the brick blanks on the conveyor belt 13 can be pushed onto the flip plate 23 more smoothly, and the mutual engagement between the positioning sleeve 29 and the positioning block 15 can ensure the matching of heights.

[0032] The outer side of the turntable 22 is fixedly connected to a central shaft that passes through the frame 21, and the outer end of the central shaft is linked to the end of the left transmission roller 12 through an intermittent linkage mechanism 3. The outer surface of the frame 21 is fixedly connected to a protective shell 4 that covers the intermittent linkage mechanism 3.

[0033] The intermittent linkage mechanism 3 includes a one-way ratchet 31 fixedly connected to the end of the central shaft, a missing gear 32 meshing and rotatingly connected to the surface of the frame 21 and located to the right of the one-way ratchet 31, a sliding sleeve 33 fixedly connected to the surface of the frame 21 and located to the top of the one-way ratchet 31, and a toothed plate 34 longitudinally slidingly connected inside the sliding sleeve 33. A ratchet 35 that engages with the one-way ratchet 31 is fixedly connected to the bottom of the toothed plate 34 to restrict the one-way ratchet 31 to rotate only counterclockwise. Synchronous pulleys 36 are fixedly connected to the surface of the frame 21 and located to the right of the missing gear 32 and at the end of the left transmission roller 12. The two synchronous pulleys 36 are connected by a synchronous belt 37. A pair of meshing gears 38 are fixedly connected to the surface of the missing gear 32 and the left synchronous pulley 36.

[0034] By setting up an intermittent linkage mechanism 3 to link the conveying mechanism 1 and the billet turning mechanism 2, the rotational power of the conveying mechanism 1 can be used to intermittently drive the billet turning mechanism 2 to perform the turning operation. The equipment operates more smoothly, eliminating the need to use and control an additional set of motor drive structures, thus saving costs.

[0035] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0036] In use, hollow brick blanks are placed orderly on the conveyor belt 13 for conveying. After the hollow brick blanks are conveyed to the right flip plate 23, subsequent hollow brick blanks cannot continue to move forward. Then, the left transmission roller 12 drives the right gear 38 to rotate through the synchronous wheel 36 and the synchronous belt 37. The left meshing gear 38 drives the missing gear 32 to rotate, which in turn drives the one-way ratchet 31 to rotate intermittently. That is, it drives the turntable 22 and the flip plate 23 to rotate intermittently, flipping the hollow brick blank to the left and making it stand up. During this process, the roller 234 of the flip plate 23 is guided by the egg-shaped track groove 25, so that the slide plate 232 gradually retracts into the sleeve plate 231. When it moves to the top, the top is lower than the hollow brick blank. Then, the robot arm is controlled to clamp the hollow brick blank and move it away.
