Description

Technical Field

[0001] This utility model relates to the field of cargo palletizing technology, and in particular to a palletizing device. Background Technology

[0002] Currently, bottled water containers (12L, 15L, 19L, etc.) used in daily life need to be stacked together for transportation. To ensure stability during transportation, multiple bottles on each layer are secured with pallets, such as... Figure 1 As shown, the card plate 1 is provided with multiple slots 11, each slot 11 corresponding to the neck of a bare barrel to fix the bare barrel, and the multiple slots 11 are arranged in multiple rows.

[0003] In related technologies, some palletizing equipment can transport bare drums one by one to a designated location and arrange them according to the arrangement of the slots 11 on the pallet 1, and then clamp the pallet 1 with the arranged bare drums. This type of palletizing equipment has low palletizing efficiency. Other palletizing equipment can first stack the bare drums into transport groups according to the arrangement of the slots 11 on the pallet 1, and then transport the transport groups as a whole to a designated location for clamping with the pallet 1. This type of palletizing equipment improves palletizing efficiency, but it is not compatible with different types of pallets 1, such as when the spacing of the slots 11 in adjacent rows on the pallet 1 is different.

[0004] Therefore, there is an urgent need for a palletizing device to solve the above-mentioned technical problems. Utility Model Content

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] This embodiment provides a palletizing device that can stack and arrange workpieces. Specifically, the workpiece 300 can be a bare drum. The following description uses a pallet 1 with six rows of slots 11 as an example.

[0050] like Figure 2As shown, the palletizing equipment includes a stacking device 100 and a stacking device 200. The stacking device 100 is used to arrange workpieces 300 into at least two rows, each row including multiple workpieces 300, and the multiple workpieces 300 extend along a first direction. Adjacent rows of workpieces 300 are spaced apart along a second direction. The stacking device 200 includes a main body mechanism 210 and at least two rows of gripping mechanisms 220 mounted on the main body mechanism 210. Each row of gripping mechanisms 220 can grip one row of workpieces 300. The gripping mechanisms 220 can move along the second direction to bring the rows of workpieces 300 closer together. The second direction and the first direction are both horizontal and perpendicular to each other.

[0051] In this embodiment of the palletizing equipment, the stacking device 100 can first arrange multiple workpieces 300 into at least two rows. Then, each gripping mechanism 220 on the stacking device 200 grips each row of workpieces 300 and places each row of workpieces 300 into a designated position, ensuring the efficiency of palletizing. Since the rows of workpieces 300 stacked by the stacking device 100 are spaced apart, and each gripping mechanism 220 can move along the second direction, the spacing between adjacent rows of workpieces 300 can be adjusted so that the arrangement of each row of workpieces 300 matches the row of slots 11 on different pallets 1, improving the applicability of the palletizing equipment.

[0052] like Figure 2 As shown, the material stacking device 100 includes a conveying mechanism 110, a sorting mechanism 120, a buffer mechanism 130, a grouping mechanism 140, and a staggered stacking mechanism 150 arranged sequentially along a first direction. The conveying mechanism 110 receives workpieces 300 and conveys them along the first direction to the sorting mechanism 120. The sorting mechanism 120 receives workpieces 300 from the conveying mechanism 110, divides them into at least two tracks, and conveys them to the buffer mechanism 130 in these tracks. The buffer mechanism 130 receives workpieces 300 from the sorting mechanism 120 and can buffer the received workpieces 300 in tracks or convey them to the grouping mechanism 140 in these tracks. The grouping mechanism 140 receives a preset number of workpieces 300 from the buffer mechanism 130 to form a transport group, and conveys the entire transport group to the staggered stacking mechanism 150. The staggered stacking mechanism 150 receives the transport groups from the grouping mechanism 140, and arranges the workpieces 300 of the transport groups in at least two rows with intervals, with some adjacent rows of workpieces 300 staggered. It should be noted that the above-mentioned preset quantity is consistent with the number of bayonets 11 on the pallet 1.

[0053] The general working process of the palletizing equipment in this embodiment is as follows: The conveying mechanism 110 conveys the workpieces 300 sequentially to the sorting mechanism 120. The sorting mechanism 120 divides the workpieces 300 into corresponding number of sorting passes according to the number of rows of slots 11 on the pallet 1. Then, the buffering mechanism 130 buffers the workpieces 300 in each pass. Next, the workpieces 300 in each pass enter the grouping mechanism 140. The grouping mechanism 140 receives the workpieces 300 in each pass according to the number of slots 11 in each row on the pallet 1, thus forming a transport group. The number of workpieces 300 in the transport group is consistent with the number of slots 11 on the pallet 1. Then, the workpieces 300 in the entire transport group are transported together. The workpieces enter the staggered stacking mechanism 150, which adjusts the position of each row of workpieces 300 along the first direction, so that some adjacent rows of workpieces 300 are staggered to correspond to the staggered arrangement of each slot 11 on the pallet 1 (at this time, except for the spacing of each row of workpieces 300 along the second direction, the arrangement of workpieces 300 is completely consistent with the pallet 1); finally, each gripping mechanism 220 of the stacking device 200 grips the corresponding row of workpieces 300 and adjusts the spacing of each row of workpieces 300 along the second direction so that the arrangement of workpieces 300 is completely consistent with the arrangement of slots 11 on the pallet 1. After the stacking device 200 places multiple workpieces 300 in the designated position, the pallet 1 is installed.

[0054] like Figure 2 As shown, the conveying mechanism 110 includes two feeding conveyor belts 111, which are arranged side by side along a second direction, and each feeding conveyor belt 111 extends along a first direction. The two feeding conveyor belts 111 can improve the conveying efficiency of the workpiece 300, thereby improving the overall palletizing efficiency of the palletizing equipment. Optionally, the feeding conveyor belts 111 can be existing belt conveyor structures, which are not specifically limited here.

[0055] like Figure 2 and Figure 3As shown, the channel separating mechanism 120 includes a channel separating conveyor belt 121, a separating component 122, and a separating component. One end of the channel separating conveyor belt 121 is connected to the conveying mechanism 110, and the other end is connected to the buffer mechanism 130. The channel separating conveyor belt 121 can convey workpieces 300 along a first direction. The separating component 122 is disposed on the upper side of the channel separating conveyor belt 121 and forms at least two channels. The channel separating conveyor belt 121 can drive the workpieces 300 in each channel to move. The separating component is disposed on the upper side of the channel separating conveyor belt 121, and its output end can swing between the entrances of adjacent channels, allowing workpieces 300 to selectively enter any one channel. In this embodiment, the dividing conveyor belt 121 is constructed as a belt conveyor structure with a relatively wide dimension along the second direction. The separating component 122 includes multiple partitions, each of which is arranged on the dividing conveyor belt 121 to form multiple channels. This arrangement ensures that the workpiece 300 is not obstructed when it is divided by the separating component along the second direction, avoiding the workpiece 300 from getting stuck or tipping over during the separation process. Moreover, the workpiece 300 is always in a forward conveying state during the separation process, ensuring the overall efficiency of the palletizing equipment.

[0056] like Figure 3 As shown, the sorting assembly includes a primary sorting assembly 124a and a secondary sorting assembly 124b. The channel includes a primary channel 123a and a secondary channel 123b. The secondary channel 123b is located at the outlet end of the primary channel 123a. The primary sorting assembly 124a is used to sort the workpiece 300 into two adjacent primary channels 123a. The secondary sorting assembly 124b is located at the end of the primary channel 123a and is used to sort the workpiece 300 in the primary channel 123a into the two secondary channels 123b.

[0057] In this embodiment, each feeding conveyor belt 111 corresponds to two primary channels 123a. One of these primary channels 123a directly connects to the buffer mechanism 130, while the other primary channel 123a has two secondary channels 123b at its outlet. Specifically, after the workpiece 300 moves from the feeding conveyor belt 111 to the dividing conveyor belt 121, the dividing component 124a divides the workpiece 300 into two adjacent primary channels 123a. The workpiece 300 in the first primary channel 123a is then divided into two secondary channels 123b by the secondary dividing component 124b. At this point, the workpiece 300 transported by the feeding conveyor belt 111 is divided into three stages. The workpiece 300 transported by the two feeding conveyor belts 111 is divided into six stages. It is understood that in other embodiments, the dividing component can be set to one, two, three, or more stages depending on the number of rows of slots 11 on the card plate 1; no specific limitation is made here.

[0058] like Figure 3As shown, in this embodiment, the primary sorting component 124a and the secondary sorting component 124b have the same structure, and both include a cylinder 1241 and a swing arm 1242. One end of the swing arm 1242 is hinged to the frame of the palletizing equipment, and the cylinder body of the cylinder 1241 is hinged to the frame of the palletizing equipment. The piston of the cylinder 1241 is hinged to the middle position of the swing arm 1242. When the cylinder 1241 outputs linear motion, the swing arm 1242 swings around the vertical axis, thereby blocking the entrance of an adjacent channel and guiding the workpiece 300 into another adjacent channel. Optionally, the sorting mechanism 120 also includes a first counter 125, which is mounted on the frame of the palletizing equipment and can count the workpieces 300 entering each channel.

[0059] like Figure 2 and Figure 4 As shown, the buffer mechanism 130 includes at least two buffer conveyor belts 131 and a first baffle assembly 132. The at least two buffer conveyor belts 131 are arranged side-by-side along a second direction. One end of each buffer conveyor belt 131 connects to a channel of the channeling mechanism 120, and the other end connects to the grouping mechanism 140. The buffer conveyor belts 131 can convey workpieces 300 along a first direction. The first baffle assembly 132 is disposed between the buffer mechanism 130 and the grouping mechanism 140. The first baffle assembly 132 can selectively block or prevent workpieces 300 from being conveyed from the buffer mechanism 130 to the grouping mechanism 140. In this embodiment, the buffer conveyor belts 131 can be existing belt conveyor structures, with each buffer conveyor belt 131 corresponding to the outlet of a channel, thereby achieving the buffering or conveying of workpieces 300 in separate channels. The buffer mechanism 130 includes a plurality of first baffle assemblies 132, each first baffle assembly 132 being disposed between a buffer conveyor belt 131 and a separating mechanism 120. That is, each first baffle assembly 132 can stop or avoid a workpiece 300 in the buffer conveyor belt 131 from entering the grouping mechanism 140. Optionally, the first baffle assembly 132 can stop or avoid the workpiece 300 by means of lifting or lowering movement.

[0060] In this embodiment, the buffer mechanism 130 also includes a full-material identification component, which can identify whether each buffer conveyor belt 131 is full of workpieces 300. The full-material identification component is communicatively connected to the conveying mechanism 110. Specifically, both the full-material identification component and the conveying mechanism 110 are communicatively connected to the controller of the palletizing equipment, thereby achieving indirect communication.

[0061] In some embodiments, when the full-load recognition component detects that all workpieces 300 on the buffer conveyor belts 131 are full, it sends a signal to the controller, which then controls the conveying mechanism 110 to stop conveying workpieces 300. In some embodiments, multiple full-load recognition components are provided, each corresponding to a specific buffer conveyor belt 131 to identify whether it is full. If the full-load recognition component detects that the corresponding buffer conveyor belt 131 is full, it sends a signal to the controller, which then controls the sorting component to stop conveying workpieces 300 onto that buffer conveyor belt 131. If all full-load conveyor belts are full, the controller sends a signal to the conveying mechanism 110, thereby stopping the conveying mechanism 110 from conveying workpieces 300. Optionally, the full-load recognition component can be a counter, a vision camera, etc., as long as it can identify the number of workpieces 300 on the corresponding buffer conveyor belt 131.

[0062] like Figure 5 As shown, the grouping mechanism 140 includes at least two grouping conveyor belts 141 and a second baffle assembly 142. The at least two grouping conveyor belts 141 are arranged side-by-side along a second direction. One end of each grouping conveyor belt 141 is connected to a buffer conveyor belt 131, and the other end is connected to a staggered stacking mechanism 150. The grouping conveyor belts 141 can transport workpieces 300 along a first direction. The second baffle assembly 142 is disposed between the grouping mechanism 140 and the staggered stacking mechanism 150. The second baffle assembly 142 can selectively block or avoid the workpieces 300 from being transported from the grouping conveyor belts 141 to the staggered stacking mechanism 150. In this embodiment, the grouping conveyor belts 141 can be an existing belt conveyor mechanism 110. The second baffle assembly 142 can achieve the effect of blocking or avoiding the workpieces 300 from being transported from the grouping conveyor belts 141 to the staggered stacking mechanism 150 through lifting and lowering movements.

[0063] Specifically, before the number of workpieces 300 on the group conveyor belt 141 reaches the same number as the number of corresponding slots 11 on the pallet 1, the second baffle assembly 142 is in a state that prevents workpieces 300 from moving from the group conveyor belt 141 to the misaligned stacking mechanism 150. When the number of workpieces 300 on all group conveyor belts 141 reaches the same number as the number of corresponding slots 11 on the pallet 1 (i.e., the total number of workpieces 300 on the entire grouping mechanism 140 is a preset number), all workpieces 300 on the grouping mechanism 140 form a transport group. At this time, the second baffle assembly 142 moves to the avoidance position, and all group conveyor belts 141 work together to transport the entire transport group to the misaligned stacking mechanism 150. In addition, during this process, the first baffle assembly 132 moves to the stop position, thereby preventing workpieces 300 in the buffer mechanism 130 from continuing to be transported to the grouping mechanism 140.

[0064] like Figure 5As shown, the grouping mechanism 140 also includes at least two second counters 143, each second counter 143 counting the workpieces 300 in a corresponding grouping conveyor belt 141. The second counters 143 are communicatively connected to the first baffle assembly 132 and the second baffle assembly 142, respectively. Specifically, the second counters 143 and the second baffle assemblies 142 are also communicatively connected to the controller of the palletizing equipment. When a second counter 143 detects that the number of workpieces 300 on the corresponding grouping conveyor belt 141 has reached the required number, it sends a signal to the controller, which then sends a signal to the corresponding first baffle assembly 132. The first baffle assembly 132 moves to a stop position to prevent the corresponding buffer conveyor belt 131 from continuing to transport workpieces 300 to the grouping conveyor belt 141. When all the second counters 143 have detected that the number of workpieces 300 on the corresponding grouping conveyor belt 141 has reached the required number, the controller controls the second baffle assembly 142 to move to an avoidance position, so that the entire transport group can move as a whole from the grouping mechanism 140 to the staggered stacking mechanism 150.

[0065] like Figure 2 and Figure 6 As shown, the staggered stacking mechanism 150 includes multiple stacking conveyor belts 151 and staggered baffles 152. The multiple stacking conveyor belts 151 are arranged side-by-side along a second direction, and each stacking conveyor belt 151 is connected to a grouping conveyor belt 141. The stacking conveyor belts 151 can transport workpieces 300 along a first direction. The staggered baffles 152 are located at the end of the stacking conveyor belts 151 away from the grouping mechanism 140. The staggered baffles 152 are provided with a first groove 1521 and a second groove 1522. Each stacking conveyor belt 151 corresponds to one first groove 1521 or one second groove 1522. The depths of the first groove 1521 and the second groove 1522 are different, and both are used to limit and stop the workpieces 300. After workpiece 300 moves from the grouping conveyor belt 141 to the stacking conveyor belt 151, the stacking conveyor belt 151 places the workpiece 300 at the misalignment baffle 152. The first workpiece 300 abuts against the groove wall of the first groove 1521 or the second groove 1522, and subsequent workpieces 300 abut against the previous workpiece 300 in the same row. This causes the workpieces 300 in different rows to be misaligned in the first direction, thus realizing the misaligned stacking of workpieces 300.

[0066] In this embodiment, the stacking conveyor belt 151 can be an existing belt conveyor structure, and the misalignment baffle 152 can be a single integral plate or multiple sheet metal pieces spliced ​​together; no specific limitation is made here. Optionally, the shapes of the first groove 1521 and the second groove 1522 can both be constructed as arc shapes that fit against the surface of the workpiece 300.

[0067] like Figure 6As shown, the misaligned stacking mechanism 150 also includes a plurality of third counters 153, which are mounted on the frame of the palletizing equipment. Each third counter 153 detects the number of workpieces 300 on a stacking conveyor belt 151, and the third counter 153 is used to confirm whether the number of workpieces 300 on the misaligned stacking mechanism 150 is consistent with the number of slots 11 on the pallet 1.

[0068] like Figure 2 and Figure 7 As shown, the gripping mechanism 220 includes a mounting plate 221 and at least two gripper assemblies 222. Both gripper assemblies 222 are mounted on the mounting plate 221, and each gripper assembly 222 is used to grip one workpiece 300, thereby enabling the gripping mechanism 220 to grip an entire row of workpieces 300. It is understood that the gripper assembly 222 is an existing structure and will not be described in detail here.

[0069] like Figure 7 As shown, the stacking device 200 also includes multiple drive mechanisms 230, which are mounted on the main body 210. Each drive mechanism 230's output end is connected to a corresponding gripping mechanism 220. Each drive mechanism 230 can drive its corresponding gripping mechanism 220 to move along a second direction, thereby adjusting the spacing between rows of workpieces 300 gripped by each gripping mechanism 220. In this embodiment, the drive mechanism 230 can be a cylinder, and its output end is connected to the mounting plate 221. Optionally, among the multiple gripping mechanisms 220, one gripping mechanism 220 may not be equipped with a drive mechanism 230, and the other gripping mechanisms 220 may all move towards that gripping mechanism 220 along the second direction.

[0070] When the workpieces 300 have different sizes, after the workpieces 300 are stacked by the staggered stacking mechanism 150, the distance between two adjacent workpieces 300 in the same row along the first direction may vary. To ensure that the stacking device 200 can smoothly grip different types of workpieces 300, each gripper assembly 222 can move relative to the mounting plate 221 along the first direction. By adjusting the position of each gripper assembly 222 in the gripping mechanism 220 along the first direction, the gripping mechanism 220 can be compatible with gripping workpieces 300 of different sizes, thereby further improving the applicability of the stacking equipment. Optionally, the gripping mechanism 220 includes multiple drive assemblies, each drive assembly driving one gripper assembly 222 to move relative to the mounting plate 221 along the first direction. Optionally, the drive assembly can be a structure of a motor and a lead screw and nut.
