Description

Technical Field

[0001] The invention relates to the technical field of cardboard palletizing, and in particular to a high-speed cardboard palletizing device. Background Art

[0002] As we all know, a cardboard palletizing device is a device used to stack cardboards neatly.

[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 generally there will be a conveyor belt. The positioning mechanism can ensure the accurate position of the cardboard during 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 palletizing, 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 to complete the palletizing.

[0004] The disadvantage of the prior art is that, in the prior art, when stacking, the cardboard is first transported to the stacking position by a conveyor belt, and after the stacking is completed, it is pushed by a pushing mechanism, so that the palletizing is completed. However, the applicant has found in actual use that in this palletizing mode, when the stacked cardboard is pushed, the conveyor belt needs to stop conveying and wait for the pushing mechanism to push the next time, that is, the machine needs to stop and wait for the pushing mechanism to push each time the stacking is performed, thereby wasting time waiting. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-speed cardboard stacking device to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0014] As a further preferred embodiment of the present invention, the upper partition and the lower partition are locked by a locking member. When the locking member is unlocked, the lower partition is driven by the elastic force of the second elastic member to move from the first state to the second state. One end of the second elastic member is connected to the sliding column, and the other end is linked to the lower partition.

[0042] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. 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 Figures 1-14 A cardboard high-speed palletizing device includes a bracket 1 and a conveyor belt 11 arranged on the bracket 1, and an upper roller and a lower roller are arranged on one end of the conveyor belt 11, 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] The conveyor frame 18 is also provided on the support frame 1, and the conveyor frame 18 is provided in the downstream area of the conveyor belt 11; the support frame 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 transported to the stacking space through the rotation of the upper roller and the lower 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 pushes the stacked cardboard, the compensation belt 4 can move toward the stacking space, thereby being able 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 downtime and improving the stacking efficiency of the cardboard.

[0049] Specifically, in this embodiment, a fixed barrier rod 14 is further provided on the bracket 1, and the fixed barrier rod 14 is below the rotating roller. Specifically, after the compensation belt 4 moves toward the stacking space to carry the cardboard conveyed by the conveyor belt 11, when the sliding push rod 15 returns to its initial position (the initial position is the position where the sliding push rod 15 is closest to the conveyor belt 11), the compensation belt 4 also returns to its initial position synchronously, that is, the cardboard carried by the compensation belt 4 is blocked by the fixed barrier rod 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 transported 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 the 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 is provided with a barrier component with two states, which can achieve the purpose of blocking the cardboard 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 the pushing stroke of the passive sliding push rod 15 can also be controlled, 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 member. When the locking member is unlocked, the lower partition 22 is driven by the elastic force of the second elastic member 222 to move from the first state to the second state. One end of the second elastic member 222 is connected to the sliding column, and the other end is linked 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 further provided with a second limiting groove 2204 that communicates with the guide slot 2203. The lower partition 22 is also provided with a second guide post 212, and the second guide post 212 can move along the guide slot 2203 into the second limiting groove 2204. The second guide post 212 is elastically slidably provided with the aforementioned locking post 2111, and the second limiting groove 2204 is also provided with the aforementioned locking slot 2201. The locking principle of the locking post 2111 is the same as that of the first guide slot 301. In the present application, the cooperation of the first guide post 211 and the second guide post 212 enables the lower partition 22 and the upper partition 21 to slide vertically relative to each other, that is, it can ensure that the lower partition 22 remains vertical during the blocking and switching states.

[0055] In an 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 pressure of the inclined block 33. Another core innovation of the present invention is that, through the cooperation of the provided locking member and the first limiting groove 2202 and other structures, the present invention can achieve that when the lower partition 22 moves upward to the second state, it can tilt away from the already stacked cardboard. That is, the lower partition 22 is prevented from directly moving vertically upward, thereby not affecting the already stacked cardboard. This ensures that the lower partition 22 can passively move upward to avoid the already stacked cardboard, and during the movement, it does not cause friction on the cardboard, causing the cardboard to be disordered, thereby 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 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 223 is also fixedly provided on the lower partition 22. During the movement of the partition assembly along the support frame 3, the guide slide 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 its coordination, but also has low cost and is convenient for later maintenance.

[0060] Specifically, side panels 17 are respectively arranged on both sides of the stacking space, and the side panels 17 are connected to the hydraulic rod on the output shaft. During stacking, the hydraulic rod reciprocates and gradually pushes the side panels 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 one end of the connecting column 2241 is inserted into the guide groove 501 provided on the sliding block 5. 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, it can passively drive the connecting column 2241 to move upward, that is, it can cooperate with the elastic force of the second elastic member 222 to quickly realize the lower partition 22 moving up to the second state, that is, it can quickly passively avoid the pushed cardboard board, and at the same time can more quickly block the cardboard on the compensation plate.

[0062] When the present invention is used, first, a batch of cardboard is conveyed between the upper roller and the lower roller by the conveyor belt 11, and then the cardboard is conveyed piece by piece to the conveyor frame 18, that is, to the stacking space, and the barrier component is in the following position: Figure 1The state shown is used to block the cardboard being transported down to ensure neatness. Then, after 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 fish-scale stacking state. 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, thereby driving the connected barrier assembly to move toward 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. 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 connection Figure 6 as well as Figure 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 post 211 and the second guide post 212 are fixed, that is, the first limiting groove 2202 of the lower partition 22 can slide relative to the first guide post 211, and similarly, the second limiting groove 2204 can also slide relative to the second guide post 212, that is, it can achieve that the lower partition 22 first tilts away from the stacked cardboard. When the first guide post 211 and the second guide post 212 are in the guide slide 2203, the guide slide 223 is at the position where the second guide groove 302 and the third guide groove 303 are connected. Then, the lower partition 22 is instantly moved upward under the elastic force of the second elastic member 222 The guide slide 223 and the lower partition 22 are in the second state at this time, and the guide slide 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 by the action of the slider 16, the sliding block 5, and the second pull rope 52. During the movement, the guide slide 223 moves along the direction of the second guide groove 302. Under the limit of the groove, the guide slide 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, as shown in FIG. Figure 13 As shown, the guide groove 2203 close to the first limiting groove 2202 is a stepped groove. Figure 13 The position a is a stepped groove, and the locking post 2111 in the locking groove 2201 in the first limiting groove 2202 is in a rounded state, that is, the locking post 2111 can pass through the stepped groove, and then the locking post 2111 in the second limiting groove 2204 can enter the locking groove 2201 in the second limiting groove 2204 along the stepped groove, and finally, the locking post 2111 is inserted into the locking groove 2201 under the elastic force of the internal spring, locking the lower partition 22, 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 transported and stacked normally, and so on, that is, palletizing without stopping the machine can be achieved.

[0063] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
