[0003] It is mainly composed of conveying mechanism, positioning mechanism, pushing mechanism and other parts. The conveying mechanism can transport the cardboard to the designated position, and there is usually a conveyor belt. The positioning mechanism can ensure the accurate position of the cardboard when stacking to prevent deviation. The stacking mechanism is the core part. Through mechanical arms or suction cups, the cardboard is stacked in a certain pattern (such as stacking layer by layer, or staggered stacking) to facilitate subsequent storage and transportation. This device can improve the efficiency and quality of cardboard stacking and reduce labor costs. When stacking, the cardboard is generally transported to the stacking position by a conveyor belt. After the stacking is completed, it is pushed by the pushing mechanism, so that the stacking is completed.

Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0043] See also Figure 1-Figure 14 A cardboard high-speed stacking device comprises a bracket 1 and a conveyor belt 11 arranged on the bracket 1, an upper rotating roller and a lower rotating roller are arranged at one end of the conveyor belt 11, and is characterized in that:

[0044] It also includes a compensation belt 4 arranged below the conveyor belt 11, and the compensation belt 4 can slide along the conveying direction of the conveyor belt 11;

[0045] It also includes a conveyor frame 18 arranged on the bracket 1, and the conveyor frame 18 is arranged in the downstream area of ​​the conveyor belt 11; the bracket 1 is also provided with a sliding push rod 15 for pushing the cardboard; the conveyor frame 18 is also provided with a stacking space;

[0046] When the sliding push rod 15 pushes the cardboard, the compensation belt 4 moves synchronously toward the stacking space to receive the cardboard conveyed by the conveyor belt 11 .

[0047] Specifically, the cardboard conveyed by the conveyor belt 11 is conveyed to the stacking space through the rotation cooperation of the upper rotating roller and the lower rotating roller;

[0048] The present invention cooperates with the compensation belt 4 and the sliding push rod 15 to achieve that during palletizing, when the sliding push rod 15 is pushing the stacked cardboard, the compensation belt 4 can move toward the direction of the stacking space, so as to carry the cardboard conveyed by the conveyor belt 11, that is, it can be achieved that when the sliding push rod 15 is pushing, the conveying can be carried out without stopping the machine, thereby greatly reducing the time waste of stopping and improving the stacking efficiency of the cardboard.

[0049] Specifically, in this embodiment, a fixed stopper 14 is further provided on the bracket 1, and the fixed stopper 14 is below the rotating roller. Specifically, after the compensation belt 4 moves toward the direction of the stacking space to carry the cardboard conveyed by the conveyor belt 11, when the sliding push rod 15 returns to the initial position, the initial position is the position where the sliding push rod 15 is closest to the conveyor belt 11, and the compensation belt 4 also returns to the initial position synchronously, that is, the cardboard carried on the compensation belt 4 is blocked by the fixed stopper 14, so that the cardboard on the compensation belt 4 is blocked in the stacking space, and then the stacking continues.

[0050] Specifically, in this embodiment, a support frame 3 is further provided on the bracket 1, and a barrier assembly is further provided below the support frame 3, and the barrier assembly can slide along the support frame 3, and the barrier assembly is used to block the cardboard conveyed to the stacking space.

[0051] In an embodiment further provided by the present invention, the barrier assembly includes a sliding block 5 slidably arranged on a support frame 3 and an upper partition 21 arranged below the sliding block 5, and a lower partition 22 is also slidably arranged on the sliding block 5, and the lower partition 22 has a first state and a second state in the vertical direction; in the first state, the lower partition 22 blocks the cardboard in the stacking space, and in the second state, the lower partition 22 is used to block the cardboard on the compensation belt 4.

[0052] The present invention, by providing a barrier component with two states, can achieve the purpose of blocking the cardboards being stacked during palletizing, that is, it can ensure the neatness of palletizing, and in the process of pushing the sliding push rod 15, when the compensation belt 4 receives the cardboard, the cardboard on the compensation belt 4 can be blocked by the barrier component, and the barrier component is set to two states, and at the same time, the pushing stroke of the passive sliding push rod 15 can be achieved, thereby greatly improving the functionality of the barrier component.

[0053] In an embodiment further provided by the present invention, the upper partition 21 and the lower partition 22 are locked by a locking piece. When the locking piece is unlocked, the lower partition 22 is driven by the elastic force of the second elastic piece 222 to move from the first state to the second state. One end of the second elastic piece 222 is connected to the sliding column, and the other end is connected to the lower partition 22.

[0054] In an embodiment further provided by the present invention, the locking member includes a first guide column 211 fixedly arranged on the upper partition 21, and a locking column 2111 is elastically slidably connected to the first guide column 211, a guide groove 2203 and a connected first limiting groove 2202 are provided on the lower partition 22, and a locking groove 2201 is provided in the first limiting groove 2202, and the locking column 2111 is inserted into the locking groove 2201 under the elastic force of the internal spring. Specifically, the lower partition 22 is also provided with a second limiting groove 2204 connected with the guide slot 2203, and the lower partition 22 is also provided with a second guide column 212, and the second guide column 212 can move along the guide slot 2203 to the second limiting groove 2204, and the second guide column 212 is elastically slidably provided with the above-mentioned locking column 2111, and the second limiting groove 2204 is also provided with the above-mentioned locking groove 2201, and its locking principle is consistent with the locking principle of the above-mentioned first guide slot 301. In the present application, the cooperation of the first guide column 211 and the second guide column 212 can realize the relative vertical sliding of the lower partition 22 and the upper partition 21, that is, it can ensure the verticality of the lower partition 22 during the blocking and switching states.

[0055] In the embodiment further provided by the present invention, an inclined block 33 is fixedly provided on the vertical plate 32, and an elastic column 221 is slidably provided on the lower partition 22, and a first elastic member 2211 is sleeved on the outer wall of the elastic column 221, and one end of the elastic column 221 can be inserted into the locking groove 2201 under the extrusion of the inclined block 33. Another core innovation of the present invention is that the present invention can achieve the tilted separation of the already stacked cardboard when the lower partition 22 moves up to the second state through the cooperation of the locking member and the first limiting groove 2202 and other structures, that is, the lower partition 22 is prevented from moving vertically directly, so as not to affect the already stacked cardboard, thereby ensuring the passive upward movement of the lower partition 22 to avoid the already stacked cardboard, and in the process of movement, it will not cause friction movement to the cardboard, causing the cardboard to be disordered, and greatly improving the functionality of the device.

[0056] In the embodiment further provided by the present invention, a vertical plate 32 is further provided below the support frame 3, and a passive limiting portion is further provided on the vertical plate 32; the lower rotating roller passes through the passive limiting portion, and during the recovery process of the sliding push rod 15, the lower partition 22 moves from the second state to the first state through the passive limiting portion.

[0057] In the solution further provided by the present invention, the passive limiting portion includes a first guide groove 301, a second guide groove 302 and a third guide groove 303 which are opened on the vertical plate 32, and the first guide groove 301 is respectively connected to the second guide groove 302 and the third guide groove 303, and a guide slide column 223 is also fixedly provided on the lower partition plate 22. During the movement of the partition assembly along the support frame 3, the guide slide column 223 slides into the passive limiting portion.

[0058] In the solution further provided by the present invention, a slider 16 is provided at the bottom of the sliding push rod 15, and the two ends of the slider 16 are respectively connected to the first pull rope 51 and the second pull rope 52, and the other ends of the first pull rope 51 and the second pull rope 52 are respectively connected to the sliding block 5.

[0059] Specifically, the first pull rope 51 is guided by the second guide wheel 511, and the second pull rope 52 is guided by the first guide wheel 521 and the third guide wheel 512. That is, when the sliding push rod 15 is moving, it can drive the sliding block 5 to move synchronously through the first pull rope 51, and then when returning, the sliding block 5 is pulled back through the second pull rope 52, that is, the synchronous movement of the partition assembly and the sliding push rod 15 can be achieved, which not only improves their coordination, but also has low cost and is convenient for later maintenance.

[0060] Specifically, side plates 17 are respectively arranged on both sides of the stacking space, and the side plates 17 are connected to the hydraulic rod on the output shaft. During stacking, the hydraulic rod reciprocates and gradually pushes the side plates 17 to squeeze the cardboard, thereby aligning the stacked cardboard.

[0061] Furthermore, a connecting rod 224 is rotatably provided on the lower partition 22, and a connecting column 2241 is fixedly provided on the upper end of the connecting rod 224, and both ends of the connecting column 2241 are inserted into the guide groove 501 provided on the sliding block 5, and a fixing block 31 is also provided on the support frame 3, and a slope is provided on the fixing block 31. When the connecting column 2241 abuts against the slope, the connecting column 2241 can be passively driven to move upward, that is, the elastic force of the second elastic member 222 can be cooperated to quickly realize the lower partition 22 to move up to the second state, that is, the pushed cardboard board can be passively avoided quickly, and the cardboard on the compensation plate can be blocked more quickly.

[0062] When the present invention is used, firstly, a batch of cardboard is conveyed to between the upper rotating roller and the lower rotating roller by the conveyor belt 11, and then the cardboard is conveyed to the conveying rack 18 piece by piece by the upper rotating roller and the lower rotating roller, that is, conveyed to the stacking space, and the barrier component is in the following state: Figure 1The state shown is used to block the cardboard being transported down to ensure neatness. Then, after being transported for a certain period of time, that is, when the cardboard is stacked to a certain thickness, the sliding push rod 15 drives the cardboard to move toward the support frame 3 and pushes the stacked cardboard to move synchronously. At the same time, the compensation belt 4 also moves synchronously to receive the cardboard continuously transported by the conveyor belt 11, and the cardboard stacked on the compensation belt 4 is in a state of fish scale stacking. During the movement, the sliding push rod 15 drives the slider 16 and the sliding block 5 connected to the slider 16 through the first pull rope 51 to move, so as to drive the connected blocking assembly to move in the direction of the support frame 3. During the movement, the elastic column 221 provided on the lower partition 22 gradually abuts against the inclined block 33 provided on the vertical plate 32, and at this time, the guide slide column 223 provided on the lower partition 22 also moves into the third guide groove 303, and then the elastic column 221 is squeezed by the inclined block 33 and gradually contracts inwardly. During the inward contraction process, the locking column 2111 in the locking groove 2201 is gradually squeezed, as shown in FIG. Figure 7 As shown, the locking column 2111 is finally completely separated from the locking groove 2201, and then the connection provided on the connecting rod 224 is gradually squeezed by the inclined surface 311 on the fixing block 31, and gradually moves upward, and the locking column 2111 is completely separated from the locking groove 2201. Figure 6 as well as Fig.11 , that is, it can drive the connected connecting rod 224 and the lower partition 22 to move upward. Since the upper partition 21 and the connected first guide column 211 and the second guide column 212 are fixed, that is, the first limiting groove 2202 of the lower partition 22 can slide relative to the first guide column 211, and similarly, the second limiting groove 2204 can also slide relative to the second guide column 212, that is, it can be achieved that the lower partition 22 is first tilted away from the stacked cardboard, and when the first guide column 211 and the second guide column 212 are in the guide slide groove 2203, the guide slide column 223 is at the position where the second guide groove 302 and the third guide groove 303 are connected, and then the lower partition 22 is instantly moved upward under the elastic force of the second elastic member 222 The lower partition 22 is in the second state, and the guide slide post 223 is in the notch position of the first guide groove 301 and the second guide groove 302, that is, it can passively avoid the stacked cardboard, so that the stacked cardboard is transported outward, and then the sliding push rod 15 moves in the initial direction. During the movement, the blocking assembly is also driven to move in the opposite direction through the action of the slider 16, the sliding block 5, and the second pull rope 52. During the movement, the guide slide post 223 moves along the direction of the second guide groove 302. Under the limitation of the groove, the guide slide post 223 and the lower partition 22 gradually move downward, and finally move to the third guide groove 303 in the horizontal state. At this time, the lower partition 22 moves to the position of the first state, such as Fig.13 As shown, the guide groove 2203 close to the first limiting groove 2202 is a stepped groove. Fig.13 There is a stepped groove at position a, and the locking column 2111 in the locking groove 2201 in the first limiting groove 2202 is in a rounded state, that is, the locking column 2111 can pass through the stepped groove, and then the locking column 2111 in the second limiting groove 2204 can enter into the locking groove 2201 in the second limiting groove 2204 along the stepped groove, and finally, the locking column 2111 is inserted into the locking groove 2201 under the elastic force of the internal spring, and the lower partition 22 is locked, and the cardboard on the compensation belt 4 finally falls into the stacking space with the cooperation of the fixed stop rod 14, and then the cardboard on the conveyor belt 11 can be normally transported and stacked, and so on, that is, non-stop stacking can be achieved.

[0063] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
