[0017] FIG. 1 shows a structural schematic diagram of an example of a bare bottle pre-grouping stacking device according to the present application. FIG. 2 shows a schematic diagram of a stacking flow of bare bottles in FIG. 1. FIG. 1 is a plan view of the bare bottle pre-grouping stacking device. As shown in FIGS. 1 and 2, the bare bottle pre-grouping stacking device includes an incoming bottle transport mechanism 100, a grouping transport mechanism 200, a stacking transport mechanism 300, and a pre-grouping mechanism. The incoming bottle transport mechanism 100 is configured to transport a plurality of rows of bare bottles 800, and the pre-grouping mechanism includes a robot arm 400 and a pre-grouping clamp 500, and the pre-grouping clamp 500 is configured to clamp the bare bottles 800 in a plurality of rows. The robot arm 400 is configured to drive the pre-grouping clamp 500 to move and / or rotate within a spatial range, thereby placing the bare bottles 800 clamped by the pre-grouping clamp 500 on the grouping transport mechanism 200 according to a palletizing direction. The grouping transport mechanism 200 has an inlet end connected to the outlet end of the incoming bottle transport mechanism 100 and a transport direction that is the same as that of the incoming bottle transport mechanism 100, and the stacking transport mechanism 300 is provided at the outlet end of the grouping transport mechanism 200 and a transport direction that is the same as that of the grouping transport mechanism 200, and the stacking transport mechanism 300 has a transport speed that is slower than that of the grouping transport mechanism 200, so that the multiple rows and multiple columns of bare bottles 800 in the multiple groups in the grouping transport mechanism 200 can be stacked on the stacking transport mechanism 300. For example, since the transport width of the incoming bottle transport mechanism 100 is limited, the number of rows of bare bottles 800 clamped by the pre-grouping clamps 500 is greater than the number of columns of bare bottles 800, whereby in FIG. 1 the row direction of the bare bottles 800 is perpendicular to the transport direction of the incoming bottle transport mechanism 100 and the column direction of the bare bottles 800 is parallel to the transport direction of the incoming bottle transport mechanism.In order to stack multiple rows and multiple columns of bare bottles 800, the robot arm 400 can be used to drive the pre-grouping clamp 500 to rotate 90 degrees on the grouping transport mechanism 200, so that the arrangement direction of the multiple rows and multiple columns of bare bottles 800 can be adjusted. Due to the difference in transport speed between the stacking transport mechanism 300 and the grouping transport mechanism 200, the multiple rows and multiple columns of bare bottles 800 in multiple groups can be stacked on the stacking transport mechanism 300.

[0018] Based on the bare bottle pre-grouping stacking apparatus shown in FIG. 1 , the bare bottle pre-grouping stacking method includes:

[0019] In S11, the bottle transport mechanism 100 is used to transport multiple rows of bare bottles 800.

[0020] In S12, the pre-grouping 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 place the multiple rows and columns of bare bottles 800 clamped by the pre-grouping clamps 500 on the grouping transport mechanism 200 according to the palletizing direction, and by way of example, the robot arm 400 is used to rotate the pre-grouping clamps 500 by 90 degrees to place the multiple rows and columns of bare bottles 800 on the grouping transport mechanism 200 according to the palletizing direction.

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

[0023] FIG. 3 shows a structural schematic diagram of another example of a bare bottle pre-grouping stacking device according to the present application. FIG. 3 is a plan view of another example of a bare bottle pre-grouping stacking device, looking down on the bare bottle pre-grouping stacking device from the air. FIG. 4 shows a schematic diagram of the bare bottle stacking flow in FIG. 3. As shown in FIGS. 3 and 4, compared to the bare bottle pre-grouping stacking device, the bare bottle pre-grouping stacking device also includes a pick-up transport mechanism 700 in addition to the incoming bottle transport mechanism 100, the grouping transport mechanism 200, the stacking transport mechanism 300, and the pre-grouping mechanism. Among them, the pick-up transport mechanism 700 has an inlet end connected to the outlet end of the incoming bottle transport mechanism 100 and a transport direction that is the same as that of the incoming bottle transport mechanism 100, and the grouping transport mechanism 200 has an inlet end connected to the side of the pick-up transport mechanism 700. The pre-grouping clamp 500 (not shown) is provided on the picking and transporting mechanism 700, and the open end of the pre-grouping clamp 500 faces the incoming bottle transporting mechanism 100 so as to clamp the multiple rows of bare bottles 800 transported by the incoming bottle transporting mechanism 100. Furthermore, since the grouping transporting mechanism 200 is provided on the side of the picking and transporting mechanism 700 and the transport directions of the two are perpendicular to each other, there is no need to rotate the pre-grouping clamp 500 by the robot arm 400 to adjust the direction of the multiple rows of bare bottles 800. The robot arm 400 can directly drive the pre-grouping clamp 500 to move parallel to the grouping transporting mechanism 200, and due to the difference in transport speed between the stacking transporting mechanism 300 and the grouping transporting mechanism 200, the multiple rows and multiple rows of bare bottles 800 in the multiple groups can be stacked on the stacking transporting mechanism 300.

[0024] Based on the bare bottle pre-grouping stacking apparatus shown in FIG. 3, the bare bottle pre-grouping stacking method includes:

[0025] In S21, the bottle transport mechanism 100 is used to transport a plurality of rows of bare bottles 800.

[0026] In S22, the pre-grouping clamps 500 are provided on the gripping and transporting mechanism 700, and the pre-grouping clamps 500 are used to grip the bare bottles 800 in a plurality of rows and columns.

[0027] In S23, the robot arm 400 is used to place the multiple rows and columns of bare bottles 800 clamped by the pre-grouping clamps 500 on the grouping transport mechanism 200 according to the palletizing direction, and, illustratively, the robot arm 400 is used to translate the pre-grouping clamps 500 in parallel to move the multiple rows and columns of bare bottles 800 so that they are placed on the grouping transport mechanism 200 according to the palletizing direction.

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

[0029] For example, the robot arm 400 may be an ABB or KUKA robot, or other parallel movement mechanism. The robot arm 400 is mounted on a base. In the bare bottle pre-grouping stacking apparatus in FIG. 1, the base may be installed above the incoming bottle transport mechanism 100 and be installed on the side of the incoming 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 faces the exit end of the incoming bottle transport mechanism 100. In the bare bottle pre-grouping stacking apparatus in FIG. 3, the base is installed on one side of the pick-up transport mechanism 700, and the robot arm 400 is connected to the pre-grouping clamp 500, and the opening of the pre-grouping clamp 500 faces the exit end of the incoming bottle transport mechanism 100.

[0030] Fig. 5 shows a structural schematic diagram of the incoming bottle transport mechanism 100 according to the present application. As shown in Fig. 5, the incoming bottle transport mechanism 100 includes a conveyor belt 101 and a guide assembly, and the guide assembly is configured to divide the conveyor belt 101 into a plurality of bottle transport passages to realize the transport of a plurality of rows of bare bottles 800. The conveyor belt 101 includes a stacking transport section 1011 and a flat chain transport section 1012, which are sequentially provided along the transport direction, and the transport length L1 of the flat chain transport section 1012 is equal to the length L2 of the bare bottles 800 clamped by the pre-grouping clamp 500. The stacking transport section 1011 mainly arranges bottles closely together, temporarily stores more bottles, and relieves forward pressure. The flat chain transport section 1012 mainly plans the storage of the number of bottles to be gripped by the pre-grouping clamp, and the transport length L1 of the flat chain transport section 1012 is the length L2 for storing the rows of bare bottles 800 to be gripped. The stacking transport section 1011 and the flat chain transport section 1012 are two different conveyor belt-like parts and jointly constitute the conveyor belt 101. In Fig. 5, the guide assembly includes guard rails 102, guide plates 103 and cross stays 104, the guard rails 102 and guide plates 103 all extending along the conveying direction of the conveyor belt 101, the two guard rails 102 are fixed to both sides of the conveyor belt 101, the cross stays 104 are fixed across the side plates on both sides of the conveyor belt 101, and some guide plates 103 are fixed to the cross stays 104 at intervals in parallel and suspended above the conveyor belt 101, thus forming three bottle transport passages, so that the bottles can be transported simultaneously through the three passages, and the efficiency of transporting and organizing the bottles is improved. As shown in Fig. 5, the side plates on both sides of the conveyor belt 101 are the outer parts of the guard rails 102. For example, a plurality of horizontal stays 104 are fixed to the side plates on both sides of the conveyor belt 101 at intervals along the direction of the guard rail 102, and the guide plate 103 is hung and locked on the horizontal stays 104 by a handle. Of course, in other embodiments, the space above the conveyor belt 101 may be divided into a plurality of 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 clamp 500 can clamp.

[0031] Fig. 5 shows a structural schematic diagram of the incoming bottle transport mechanism 100 according to the present application. As shown in Fig. 5, in order to ensure that the pre-grouping clamp 500 can grab a plurality of rows of bare bottles 800 with a preset number of rows, the bare bottle pre-grouping stacking device further includes a bottle blocking mechanism 600, which includes a bottle blocking drive and a bottle blocking tool, the bottle blocking drive is provided at the bottom of the outlet end of the incoming bottle transport mechanism 100, and the bottle blocking drive is configured to drive the up and down movement of the bottle blocking tool so that the bottle blocking tool has a bottle blocking position where it blocks the outlet end of the incoming bottle transport mechanism 100 and a retreat position where it returns below the outlet end of the incoming bottle transport mechanism 100. In Fig. 5, the bottle blocking tool is a columnar structure, and multiple bottle blocking tools are arranged at the outlet end of the conveyor belt 101 at intervals along a direction perpendicular to the conveying direction of the conveyor belt 101, and it is only necessary to ensure that the distance between the bottle blocking tools is smaller than the width of the bare bottles 800. The bottle cutoff actuator may be an air cylinder, an electric cylinder, a linear motor, or the like.

[0032] In order to realize the automation of the bare bottle pre-grouping stacking device, a first sensor and a second sensor are further provided. Among them, the first sensor is provided on the conveyor belt 101 and is configured to detect when the flat chain transport section 1012 of the conveyor belt 101 is full of bottles and reaches a predetermined position, so that the bottle blocking mechanism 600 is activated to release the bottles and transport all bare bottles 800 arranged on the flat chain transport section 1012 to the pre-grouping clamp 500 abutting thereto. The number of rows of bare bottles 800 on 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 hold. The second sensor is provided on the pre-grouping clamp 500 and is configured to detect whether the pre-grouping clamp 500 is full. If the pre-grouping clamp 500 is full, the bottle blocking mechanism 600 starts to operate to block the bottles. Exemplarily, 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 another type of sensor that can detect when the bottle is filled at the flat chain transport section 1012, and no particular examples will be given here. The second sensor may be another type of sensor that can detect when the bottle is filled at the pre-grouping clamp 500, and no particular examples will be given here.

[0033] The above-mentioned bare bottle pre-grouping stacking device can perform pre-grouping stacking by simultaneously picking up multiple rows and multiple columns of bare bottles 800, which greatly reduces the number of pre-grouping, shortens the time for stacking bare bottles, and greatly improves the efficiency of pre-grouping stacking, and simultaneously, multiple rows are directly butted against the input bottle transport mechanism 100, so that all the bare bottles 800 in the rows that can be transported by the input bottle transport mechanism 100 enter the pre-grouping clamps 500, which is accurate in counting and simple to control, and the pre-grouping clamps 500 are rotated or translated using the robot arm 400, which is simple to operate. Compared with the method in which each clamping claw correspondingly picks up one bottle, this is more reliable and stable, and there is no need to pick up and lift up the bottles, which greatly reduces the error rate and failure rate of bottles being dropped, leaking, or the clamping claws being misaligned and unable to pick up the bottles.

[0034] FIG. 6 shows a structural schematic diagram of a pre-grouping clamp 500 according to the present application. As shown in FIG. 6, the pre-grouping clamp 500 includes a mounting base 1, an arrangement mechanism 3, and a clamp mechanism 2. The mounting base 1 includes a mounting plate 11, a first connector 12, and a second connector 13, the first connector 12 is configured to be connected to the arrangement 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 connection column, and the second connector 13 may be a connection flange. The first ends of the multiple first connectors 12 are fixed to the mounting plate 11, and the second ends thereof are fixedly connected to the arrangement mechanism 3. The arrangement mechanism 3 includes a position restriction plate 31 and a partition plate 32, at least two partition plates 32 are fixed to the position restriction plate 31 in parallel with a gap therebetween, a bottle clamping space is formed between two adjacent partition plates 32, and the open end of the bottle clamping space faces the outlet end of the incoming bottle transport mechanism 100. Exemplarily, the partition plates 32 are fixed to the first connectors 12, and each partition plate 32 is fixedly connected to the attachment plate 11 via a plurality of first connectors 12. The clamp mechanism 2 includes a drive assembly and a clamp plate 25, the drive assembly is provided on the attachment plate 11, and the drive assembly 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 clamping waiting position located outside the bottle clamping space.

[0035] 6 and 7, the drive assembly comprises a clamp driver 21, an attachment arm 22 and a bending arm 23, the clamp driver 21 is provided on the mounting plate 11, a first end of the attachment arm 22 is fixed to the mounting plate 11 and its second end is pivotally connected to the curved portion of the bending arm 23 via a rotating shaft 24, a first branch arm 231 of the bending arm 23 is pivotally connected to the output shaft of the clamp driver 21 and its second branch arm 232 is fixedly connected to the clamp plate 25, and the clamp driver 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, but rather rotates it using the conveyor belt 101 of the grouping transport mechanism 200, or moves it parallel to the conveyor belt 101 of the grouping transport mechanism 200 using the conveyor belt 101 of the grabbing transport mechanism 700. Therefore, the clamp plate 25 does not need to provide a large clamping force to prevent the bare bottle 800 from falling, but only needs to clamp and position it.

[0036] FIG. 7 shows a structural schematic diagram of the clamp mechanism 2 according to the present application. As shown in FIG. 7, the clamp plate 25 is provided with a shunt groove 251. Exemplarily, when the number of partition plates 32 is greater than three, the clamp plate 25 is provided with the shunt groove 251 for accommodating the partition plates 32. In FIG. 7, the number of partition plates 32 is four, and the four partition plates 32 form three bottle clamping spaces. The mounting arm 22 and the rotating shaft 24 are pivotally 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 a packaging machine equipped with the bare bottle pre-grouping stacking device as described above. The packaging machine applies the bare bottle pre-grouping device to pre-group a plurality of bare bottles 800 to form a stack, and can quickly improve the efficiency of pre-grouping the bare bottles 800. Compared with the conventional embodiment in which each clamping claw correspondingly picks up one bottle, this is more reliable and stable, and there is no need to pick up and lift the bottle, which greatly reduces the error rate and failure rate of dropping the bottle, leaking and picking, or the clamping claws being misaligned and unable to pick up the bottle. The packaging machine can simultaneously pick up multiple rows and columns of bare bottles 800 to perform pre-grouping and stacking, which greatly reduces the number of pre-groupings, reduces the time required for stacking bare bottles, and greatly improves the efficiency of pre-grouping and stacking.

[0038] Next, for example, the bare bottles 800 are picked up once every 8 rows and 3 columns, and the bare bottles 800 in 9 rows and 8 columns are arranged in groups and stacked. The transport direction of the incoming bottle transport mechanism 100 is the same as that of the grouping transport mechanism 200. The pre-grouping stacking process is as follows: First, the pre-grouping clamp 500 directly abuts against the outlet end of the incoming bottle transport mechanism 100, the clamp driver 21 contracts, and the clamp plate 25 is in a horizontal state, facilitating the entry of the bare bottles 800. When the first sensor of the incoming bottle transport mechanism 100 detects that the bottles are full and have reached the designated position, the bottle blocking mechanism 600 at the outlet end of the flat chain transport section 1012 activates to release the bottles and transport 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 them, and at the same time the stacking transport section 1011 of the incoming bottle transport mechanism 100 stops transporting bottles, and after the pre-grouping clamp 500 senses that the last bottle has reached the designated position, the clamp driver 21 drives the clamp plate 25 to extend and rotate around the rotation axis 24, and stops when the clamp plate 25 has rotated to an almost vertical position, and at the same time the bottle blocking mechanism 600 returns to its original position to block the bottles, and the stacking transport section 1011 starts up to continue transporting bottles to the flat chain transport section 1012. Next, with the action of the robot arm 400, the pre-grouping clamps 500 pick up the bare bottles in 8 rows and 3 columns and rotate 90° on the conveyor belt 101 of the pre-grouping transport mechanism 200. The robot arm 400 then rises vertically until the clamps are a certain distance higher than the tops of the bare bottles, gradually moving the pre-grouping clamps 500 upward so as to separate them from the bare bottles 800. The clamp driver 21 contracts and drives the clamp plate 25 to rotate around the rotation axis 24 until it returns to an approximately horizontal position. The robot arm 400 again quickly moves the pre-grouping clamps 500 to the outlet end of the input bottle transport mechanism 100 so as to butt them together. At this time, the flat chain transport section 1012 of the input bottle transport mechanism 100 has already detected that the bottles have been filled and transported to the specified position, and the robot arm 400 again grabs the bare bottles 800 for the second time.By circulating according to this principle and successively picking up and turning the bottles 304 and 306, the bare bottles 800 are stacked and arranged in 9 rows and 8 columns in the stacking transport mechanism 300, thereby greatly improving the efficiency of pre-group stacking.

[0039] The bare bottle pre-grouping stacking device of the present application can realize stacking of bare bottles in multiple groups, multiple rows and multiple columns, with high stacking efficiency and able to meet the needs of high-speed production lines.

[0040] The method for pre-grouping and stacking bare bottles according to the present application is based on the above-mentioned bare bottle pre-grouping and stacking device, and can quickly palletize bare bottles to improve palletizing efficiency.

[0041] The packaging equipment of the present application employs the above-mentioned bare bottle pre-grouping stacking device, thereby achieving high efficiency in stacking bare bottles.
