[0017] Figure 1 shows a schematic diagram of the structure of an example of a pre-grouped stacking device for bare bottles according to the present invention. Figure 2 shows a schematic diagram of the stacking flow of bare bottles in Figure 1. Figure 1 is a plan view of the pre-grouped stacking device for bare bottles. As shown in Figures 1 and 2, the pre-grouped stacking device for bare bottles comprises a bottle transport mechanism 100, a group transport mechanism 200, a stacking transport mechanism 300, and a pre-group transport mechanism. Of these, the bottle transport mechanism 100 is configured to transport multiple rows of bare bottles 800, and the pre-group transport mechanism comprises a robot arm 400 and a pre-group transport clamp 500, the pre-group transport clamp 500 is configured to grip multiple rows of bare bottles 800, and the robot arm 400 drives the pre-group transport clamp 500 to move and / or rotate within a spatial range, thereby moving the bare bottles 800 gripped by the pre-group transport clamp 500. Line up It is configured to be placed in the group formation transport mechanism 200 according to the direction. The group formation transport mechanism 200 is Input terminal The bottle transport mechanism 100 Output terminal The stacking transport mechanism 300 is connected to the group transport mechanism 200, and its transport direction is the same as that of the bottle transport mechanism 100. Output terminalSince the stacking transport mechanism 300 is provided and its transport direction is the same as that of the group transport mechanism 200, and the transport speed of the stacking transport mechanism 300 is smaller than that of the group transport mechanism 200, it is possible to stack multiple rows and multiple columns of bare bottles 800 from multiple groups in the group transport mechanism 200 into the stacking transport mechanism 300. For example, because the transport width of the bottle transport mechanism 100 is limited, the number of rows of bare bottles 800 held by the pre-grouping clamp 500 is greater than the number of columns of bare bottles 800, and in Figure 1, the row direction of the bare bottles 800 is perpendicular to the transport direction of the bottle transport mechanism 100, and the column direction of the bare bottles 800 is parallel to the transport direction of the bottle transport mechanism. To stack multiple rows and multiple columns of bare bottles 800, the robotic arm 400 can be used to drive the pre-grouping clamp 500 to rotate 90° in the grouping transport mechanism 200, thereby adjusting the arrangement direction of the multiple rows and multiple columns of bare bottles 800. Due to the difference in transport speed between the stacking transport mechanism 300 and the grouping transport mechanism 200, multiple groups of multiple rows and multiple columns of bare bottles 800 can be stacked in the stacking transport mechanism 300.

[0018] Based on the bare bottle pre-grouping and stacking device shown in Figure 1, the bare bottle pre-grouping and stacking method includes the following:

[0019] In S11, multiple rows of unpackaged bottles 800 are transported using the bottle transport mechanism 100.

[0020] In S12, a pre-grouped clamp 500 is used to clamp multiple rows and multiple columns of bare bottles 800.

[0021] In S13, the robot arm 400 is used to grip multiple rows and multiple columns of bare bottles 800 that have been pre-grouped by the clamp 500. Line up Place the bottles in the group formation transport mechanism 200 according to the direction, and, as an example, use the robotic arm 400 to rotate the pre-group formation clamp 500 by 90° to move multiple rows and multiple columns of bare bottles 800. Line up Place the group into the transport mechanism 200 according to the direction.

[0022] In S14, due to the difference in transport speed between the group transport mechanism 200 and the stacking transport mechanism 300, multiple groups of bare bottles 800 in multiple rows and multiple columns can be stacked in the stacking transport mechanism 300.

[0023] Figure 3 shows a schematic diagram of the structure of another example of the bare bottle pre-grouping stacking device according to the present invention. Figure 3 is a plan view of another example of the bare bottle pre-grouping stacking device, viewed from above. Figure 4 shows a schematic diagram of the bare bottle stacking flow in Figure 3. As shown in Figures 3 to 4, the bare bottle pre-grouping stacking device, compared to the bare bottle pre-grouping stacking device described above, also includes a gripping and transporting mechanism 700 in addition to the bottle transporting mechanism 100, the grouping and transporting mechanism 200, the stacking and transporting mechanism 300, and the pre-grouping mechanism. Of these, the gripping and transporting mechanism 700 is Input terminal The bottle transport mechanism 100 Output terminal The transport direction is the same as that of the bottle transport mechanism 100, and the group transport mechanism 200 is Input terminal The gripping and transporting mechanism 700 is connected to the side of the gripping and transporting mechanism 700. A pre-grouping clamp 500 (not shown) is provided on the gripping and transporting mechanism 700, and the open end of the pre-grouping clamp 500 faces the bottle transporting mechanism 100 so as to grip multiple rows of bare bottles 800 that are transported by the bottle transporting mechanism 100. Furthermore, since the group transporting mechanism 200 is provided on the side of the gripping and transporting mechanism 700 and the transport directions of the two are perpendicular, there is no need to rotate the pre-grouping clamp 500 with the robot arm 400 to adjust the direction of multiple rows of bare bottles 800. Instead, the pre-grouping clamp 500 can be directly driven to move parallel to the group transporting mechanism 200 using the robot arm 400. Due to the difference in transport speed between the stacking and transporting mechanism 300 and the group transporting mechanism 200, multiple groups of multiple rows of bare bottles 800 can be stacked in the stacking and transporting mechanism 300.

[0024] Based on the bare bottle pre-grouping and stacking device shown in Figure 3, the bare bottle pre-grouping and stacking method includes the following:

[0025] In S21, multiple rows of unpackaged bottles 800 are transported using the bottle transport mechanism 100.

[0026] In S22, a pre-grouping clamp 500 is installed on the gripping and transporting mechanism 700, and the pre-grouping clamp 500 is used to grip and pick up multiple rows and multiple columns of bare bottles 800.

[0027] In S23, the robotic arm 400 is used to grip multiple rows and multiple columns of bare bottles 800 that have been pre-grouped by the clamp 500. Line up The group formation and transport mechanism 200 is placed according to the direction, and, as an example, the robotic arm 400 is used to move the pre-group formation clamp 500 in parallel, and the bare bottles 800 in multiple rows and multiple columns are placed in the group formation and transport mechanism 200. Line up Move the group to be placed in the group formation transport mechanism 200 according to the direction.

[0028] In S24, due to the difference in transport speed between the group transport mechanism 200 and the stacking transport mechanism 300, multiple groups of multiple rows and multiple columns of bare bottles 800 can be stacked in the stacking transport mechanism 300.

[0029] Exemplary, the robot arm 400 may be an ABB or KUKA robot, or another translation mechanism. The robot arm 400 is mounted on a base. In the bare bottle pre-grouping stacking device shown in Figure 1, the base is mounted above the bottle transport mechanism 100, or it may be mounted on the side of the bottle transport mechanism 100, and the robot arm 400 is connected to the pre-grouping clamp 500, and the opening of the pre-grouping clamp 500 is the opening of the bottle transport mechanism 100 Output terminal The following describes the pre-group stacking device for bare bottles shown in Figure 3. The base is provided on one side of the gripping and transporting mechanism 700, the robot arm 400 is connected to the pre-group clamp 500, and the opening of the pre-group clamp 500 is connected to the bottle transporting mechanism 100. Output terminal To face.

[0030] Figure 5 shows a schematic diagram of the structure of the bottle transport mechanism 100 according to the present invention. As shown in Figure 5, the bottle transport mechanism 100 comprises a conveyor belt 101 and a guide assembly, the guide assembly configured to divide the conveyor belt 101 into multiple bottle transport passages in order to transport multiple rows of bare bottles 800. The conveyor belt 101 comprises a stacking transport section 1011 and a flat plate chain transport section 1012 which are sequentially provided along the transport direction, the transport length L1 of the flat plate chain transport section 1012 being equal to the length L2 of the bare bottles 800 that have been clamped by the pre-grouping clamp 500. The stacking transport section 1011 mainly arranges bottles closely together to temporarily store more bottles and reduce forward pressure. The flat chain transport section 1012 is primarily designed to store the number of items to be grasped by the pre-grouped clamps, and the transport length L1 of the flat chain transport section 1012 is the length L2 that stores multiple rows of bare bottles 800 to be grasped. The stacking transport section 1011 and the flat chain transport section 1012 are two different conveyor belt-like components that together constitute the conveyor belt 101. In Figure 5, the guide assembly comprises guardrails 102, guide boards 103, and horizontal stays 104. Both the guardrails 102 and guide boards 103 extend along the transport direction of the conveyor belt 101. The two guardrails 102 are fixed to both sides of the conveyor belt 101, the horizontal stays 104 are fixed across the side plates on both sides of the conveyor belt 101, and several guide boards 103 are fixed to the horizontal stays 104 at parallel intervals and suspended above the conveyor belt 101. This forms three bottle transport passages, allowing bottles to be transported simultaneously through the three passages, thereby increasing the efficiency of bottle transport and organization. As shown in Figure 5, the side plates on both sides of the conveyor belt 101 are the outer parts of the guardrails 102. For example, multiple horizontal stays 104 are fixed to the side plates on both sides of the conveyor belt 101 at intervals along the direction of the guardrail 102, and the guide plate 103 is suspended and locked to the horizontal stays 104 by a handle. Of course, in other embodiments, the area above the conveyor belt 101 may be partitioned into multiple bottle transport passages in other ways, and the number of bottle transport passages can be designed according to the number of rows that the pre-grouping clamps 500 can grip.

[0031] Figure 5 shows a schematic diagram of the structure of the bottle transport mechanism 100 according to the present invention. As shown in Figure 5, in order to ensure that the pre-grouping clamp 500 can grasp multiple rows of bare bottles 800 of a predetermined number of rows, the bare bottle pre-grouping stacking device further comprises a bottle blocking mechanism 600, the bottle blocking mechanism 600 comprises a bottle blocking drive and a bottle blocking device, the bottle blocking drive is of the bottle transport mechanism 100 Output terminal The bottle shut-off drive is located at the bottom of the bottle shut-off mechanism 100. Output terminal The bottle blocking position and the bottle transport mechanism 100 Output terminal The bottle barrier is configured to drive the upward and downward movement of the bottle barrier so that it has a retraction position to return to below. In Figure 5, the bottle barrier is a columnar structure, and the multiple bottle barriers are spaced apart along the conveyor belt 101 in a direction perpendicular to the transport direction of the conveyor belt 101. Output terminal The bottle shut-off devices should be arranged in such a way that it is sufficient to ensure that the distance between them is less than the width of the bare bottle 800. The bottle shut-off drive device can be an air cylinder, an electric cylinder, or a linear motor, etc.

[0032] To automate the operation of the bare bottle pre-grouping stacking device, a first sensor and a second sensor are further provided. The first sensor is provided on the conveyor belt 101 and is configured to detect when the bottles have filled the flat chain transport section 1012 of the conveyor belt 101 and reached a predetermined position, so that the bottle blocking mechanism 600 activates to release the bottles and transport all the bare bottles 800 arranged in the flat chain transport section 1012 to the pre-grouping clamp 500 that abuts against them. The number of rows of bare bottles 800 in the flat chain transport section 1012 is the same as the number of rows of bare bottles 800 that the pre-grouping clamp 500 can grip. The second sensor is provided on the pre-grouping clamp 500 and is configured to detect whether or not the pre-grouping clamp 500 is full. If the pre-grouping clamp 500 is full, the bottle blocking mechanism 600 starts to activate and block the bottles. For example, the first sensor may be a photoelectric sensor, and the second sensor may also be a photoelectric sensor. Of course, in other embodiments, the first sensor may be of a different type, as long as it can detect that the bottle is full in the flat chain transport unit 1012, and individual examples will not be given here. The second sensor may be of a different type, as long as it can detect that the bottle is full in the pre-grouping clamp 500, and individual examples will not be given here.

[0033] The above-described bare bottle pre-grouping stacking device can perform pre-grouping stacking by simultaneously grasping multiple rows and columns of bare bottles 800, significantly reducing the number of pre-grouping steps, decreasing the time required for bare bottle stacking, and greatly increasing the efficiency of pre-grouping stacking. Since multiple rows simultaneously abut directly against the bottle transport mechanism 100, all bare bottles 800 in the columns that the bottle transport mechanism 100 can transport enter the pre-grouping clamp 500, resulting in accurate counting and simple control. The pre-grouping clamp 500 can be rotated or moved using the robotic arm 400, making operation easy. Compared to the method in related technologies where each gripping claw corresponds to grasping one bottle, this method is more reliable and stable, and eliminates the need to grasp and lift the bottles, significantly reducing the error rate and failure rate due to dropped bottles, leaks during grasping, or slippage of the gripping claws.

[0034] Figure 6 shows a schematic diagram of the structure of the pre-grouping clamp 500 according to the present invention. As shown in Figure 6, the pre-grouping clamp 500 comprises a mounting base 1, an array mechanism 3, and a clamping mechanism 2. The mounting base 1 comprises a mounting plate 11, a first connector 12, and a second connector 13. The first connector 12 is configured to be connected to the array mechanism 3, and the second connector 13 is configured to be fixedly connected to the robot arm 400. The first connector 12 may be a connecting column, and the second connector 13 may be a connecting flange. The first ends of the multiple first connectors 12 are fixed to the mounting plate 11, and their second ends are fixedly connected to the array mechanism 3. The array mechanism 3 comprises a position regulating plate 31 and a partition plate 32. At least two partition plates 32 are fixed to the position regulating plate 31 at a distance from each other in parallel, forming a bottle-holding space between two adjacent partition plates 32, and the open end of the bottle-holding space is connected to the bottle transport mechanism 100. Output terminalFor example, the partition plates 32 are fixed to the first connectors 12, and each partition plate 32 is fixedly connected to the mounting plate 11 via a plurality of first connectors 12. The clamping mechanism 2 comprises a drive assembly and a clamp plate 25, the drive assembly is provided on the mounting plate 11 and is configured to drive the rotation of the clamp plate 25, and the clamp plate 25 has a bottle-clamping position located within the bottle-clamping space and a non-clamping position located outside the bottle-clamping space.

[0035] In Figures 6 and 7, the drive assembly comprises a clamp drive 21, a mounting arm 22, and a bending arm 23. The clamp drive 21 is provided on the mounting plate 11, the first end of the mounting arm 22 is fixed to the mounting plate 11, and its second end is pivotally attached to the curved portion of the bending arm 23 via a rotating shaft 24. The first branch arm 231 of the bending arm 23 is pivotally attached to the output shaft of the clamp drive 21, and its second branch arm 232 is fixedly connected to the clamp plate 25. The clamp drive 21 is configured to drive the bending arm 23 to rotate around the center of the rotating shaft 24, thereby enabling the clamp plate 25 to rotate into the bottle-clamping space and clamp the bare bottle 800 in cooperation with the position regulating plate 31 and the partition plate 32, or to rotate the clamp plate 25 to a position parallel to the bottle-clamping space so that the bare bottle 800 can enter the bottle-clamping space from the opening of the bottle-clamping space. The robot arm 400 does not need to lift and operate the pre-grouping clamp 500; it can be rotated on the conveyor belt 101 of the grouping transport mechanism 200, or moved parallel to the conveyor belt 101 of the grouping transport mechanism 200 on the conveyor belt 101 of the gripping transport mechanism 700. Therefore, the clamp plate 25 does not need to provide a large clamping force to prevent the bare bottles 800 from falling; it only needs to be able to clamp and position them.

[0036] Figure 7 shows a schematic diagram of the structure of the clamping mechanism 2 according to the present invention. As shown in Figure 7, the clamping plate 25 is provided with a retraction groove 251. Exemplarily, when the number of partition plates 32 is greater than three, the clamping plate 25 is provided with a retraction groove 251 for accommodating the partition plates 32. In Figure 7, there are four partition plates 32, and the four partition plates 32 form three bottle-clamping spaces. The mounting arm 22 and the rotating shaft 24 are rotatably connected via the bearing seat 242 of the mounting arm 22, and the bending arm 23 and the rotating shaft 24 are fixedly connected.

[0037] This embodiment further provides packaging equipment equipped with the above-described pre-grouping stacking device for bare bottles. By applying the above-described pre-grouping device for bare bottles 800, the packaging equipment can pre-group multiple bare bottles 800 to form a stack, thereby rapidly increasing the efficiency of pre-grouping bare bottles 800. Compared to the conventional method in which each gripping claw corresponds to and grasps one bottle, this method is more reliable and stable, and there is no need to grasp and lift the bottle, significantly reducing the error rate and failure rate such as dropping bottles, grasping leaks, or failing to grasp bottles due to the gripping claws slipping. The packaging equipment can perform pre-grouping stacking by simultaneously grasping multiple rows and multiple columns of bare bottles 800, significantly reducing the number of pre-grouping operations, reducing the time required for stacking bare bottles, and greatly increasing the efficiency of pre-grouping stacking.

[0038] Next, taking the example where the bare bottles 800 are picked up once each time they form an 8x3 arrangement, and the bare bottles 800 forming a 9x8 arrangement are stacked by being arranged as a group, the transport direction of the bottle transport mechanism 100 is the same as the transport direction of the group formation transport mechanism 200. The pre-group formation stacking process is as follows. First, the pre-group formation clamp 500 directly connects to the bottle transport mechanism 100. Output terminal As they come into contact, the clamp drive 21 retracts, the clamp plate 25 is in a horizontal position, and the bare bottle 800 enters easily. When the first sensor of the bottle transport mechanism 100 detects that the bottle is full and has reached a predetermined position, the flat plate chain transport section 1012 Output terminal The bottle blocking mechanism 600 activates to release the bottles, transporting the three rows of bare bottles 800 in the flat chain transport section 1012 into the three bottle clamping spaces of the pre-grouping clamp 500 that abuts against them. Simultaneously, the stacking transport section 1011 of the bottle transport mechanism 100 stops transporting bottles. After the pre-grouping clamp 500 senses that the last bottle has reached its designated position, the clamp driver 21 drives the clamp plate 25 to extend and rotate around the rotation axis 24, stopping when the clamp plate 25 is rotated to a nearly vertical position. At the same time, the bottle blocking mechanism 600 returns to its original position and blocks the bottles, and the stacking transport section 1011 activates to continue transporting bottles to the flat chain transport section 1012. Next, the pre-grouping clamp 500, under the action of the robot arm 400, lifts the 8 rows and 3 columns of bare bottles, rotates 90° on the conveyor belt 101 of the pre-grouping transport mechanism 200, and then the robot arm 400 moves vertically upward until the clamp is a certain distance above the top of the bare bottles, gradually moving the pre-grouping clamp 500 upward to detach it from the bare bottles 800. The clamp drive 21 retracts and drives the clamp plate 25 to rotate around the rotation axis 24 until it returns to a nearly horizontal position, and the robot arm 400 quickly returns the pre-grouping clamp 500 to the bottle transport mechanism 100. Output terminal The bottles are moved to a position where they meet, and at this time, the flat chain transport section 1012 of the bottle transport mechanism 100 detects that the bottles have already filled up, been transported, and reached their designated position, and then the second round of grasping the bare bottles 800 is performed. This principle is repeated, and after grasping and turning the bottles three times in succession, the stacking transport mechanism 300 forms a configuration in which the bare bottles 800 are stacked in 9 rows and 8 columns, greatly increasing the efficiency of pre-grouped stacking.

[0039] The bare bottle pre-grouping stacking device according to the present invention is capable of stacking bare bottles in multiple rows and multiple columns in multiple groups, offering high stacking efficiency and meeting the needs of high-speed production lines.

[0040] The pre-grouped stacking method for bare bottles according to the present invention rapidly stacks bare bottles based on the pre-grouped stacking device for bare bottles. Line up do, Line up This can increase efficiency.

[0041] The packaging equipment relating to this application achieves high efficiency in stacking unpackaged bottles by applying the above-mentioned pre-grouped stacking device for unpackaged bottles.
