Description

Technical Field

[0001] The utility model relates to a stacking device for bottles. Background Art

[0002] After the bottles are closely arranged to form a structure with a regular cross-section, they are usually stacked into piles in subsequent processes. The stacking design of the bottles aims to improve the space utilization efficiency, facilitate transportation and warehousing, contribute to the reduction of logistics costs and the optimization of the automated production process.

[0003] However, in the link of bottle stacking, most enterprises still rely on the traditional manual operation mode. This practice is not only inefficient, but also significantly increases the labor intensity of workers, resulting in high labor costs and a large amount of unnecessary occupation of workshop space. Manual stacking often requires two people to cooperate to complete, and the potential safety hazards in this process cannot be underestimated. The potential accident risks pose a threat to the personal safety of workers. This makes on-site management complicated, difficult to maintain order, and the working environment appears messy. Coupled with the fact that in actual operation, the situation of bottles falling when handling the whole layer occurs from time to time, which not only directly affects the production efficiency, but also may damage the product quality and cause unnecessary economic losses.

[0004] Under the combined action of the above various factors, the operation cost is pushed to a high level, and it is difficult for enterprises to maintain competitiveness in the ever-changing market environment. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to propose a stacking device for bottles with a high degree of mechanization and low operation cost in view of the above technical status.

[0006] The technical solution adopted by the utility model to solve the above technical problem is as follows: a stacking device for bottles, characterized in that it includes a guide rail extending in the vertical direction and at least two groups of clamping components, the clamping components can lift along the guide rail, and each group of the clamping components includes:

[0007] A bracket assembly, including an outer bracket and an inner bracket, and the inner bracket is closer to the shelf for placing bottles than the outer bracket;

[0008] A support assembly, connected to the inner bracket, for supporting the shelf;

[0009] A driving assembly, installed on the outer bracket, for driving the inner bracket and the support assembly to move;

[0010] The corresponding driving assembly drives the corresponding inner bracket to move, so that the clamping device has a clamping state in which each support assembly moves relatively closer to support the shelf from below, and a disengaged state in which each support assembly moves relatively away from the shelf.

[0011] There are various optional structures for how the driving component drives the inner support. Considering the driving smoothness and accuracy, preferably, each group of the stacking components includes at least one set of transmission components. Each set of the transmission components includes a first transmission rod and a second transmission rod. A rotating shaft passes through the middle parts of the first transmission rod and the second transmission rod, and the first transmission rod and the second transmission rod can rotate around the rotating shaft;

[0012] The upper end of the first transmission rod is rotatably connected to the upper part of the outer support relative to the outer support, and the lower end of the first transmission rod is rotatably connected to the lower part of the inner support relative to the inner support;

[0013] The lower end of the second transmission rod is rotatably connected to the lower part of the outer support relative to the outer support, and the upper end of the second transmission rod is rotatably connected to the upper part of the inner support relative to the inner support;

[0014] The upper end of the first transmission rod and the upper end of the second transmission rod can slide vertically relative to the respective supports they are connected to, or the lower end of the first transmission rod and the lower end of the second transmission rod can slide vertically relative to the respective supports they are connected to, so as to drive the inner support to move horizontally.

[0015] To enable the entire inner support to move horizontally smoothly and synchronously under the driving action, preferably, each group of the stacking components includes two sets of transmission components. A first outer connecting rod connects the outer ends of the first transmission rods of one set of the transmission components and the outer ends of the first transmission rods of the other set of the transmission components;

[0016] A first inner connecting rod connects the inner ends of the first transmission rods of one set of the transmission components and the inner ends of the first transmission rods of the other set of the transmission components;

[0017] A second outer connecting rod connects the outer ends of the second transmission rods of one set of the transmission components and the outer ends of the second transmission rods of the other set of the transmission components;

[0018] A second inner connecting rod connects the inner ends of the second transmission rods of one set of the transmission components and the inner ends of the second transmission rods of the other set of the transmission components;

[0019] A connecting sleeve is provided at the power output end of the driving component. The connecting sleeve is sleeved outside the second outer connecting rod and supports the second outer connecting rod, and the second outer connecting rod can rotate relative to the connecting sleeve.

[0020] To avoid crushing the bottles, it is necessary for the support component to support each shelf independently. Preferably, the support component includes at least two support members. Each support member includes a laterally extending section, and the upper surface of the laterally extending section can abut against the shelf up and down to change the stacking device into a clamping state.

[0021] To prevent the arrangement of the bottle bodies from becoming disordered or even falling off the shelf during the stacking process, preferably, each set of the clamping and stacking components further includes a clamping plate assembly installed on the inner side surface of the inner bracket. The clamping plate assembly includes at least two clamping plate members. One clamping plate member is correspondingly arranged above each support member. The clamping plate member is in the shape of a horizontally extending plate and has a vertically extending surface for contacting the outer side wall of the bottle body. When the stacking device is in the clamping and stacking state, the clamping plate assembly clamps the outer side wall of the bottle.

[0022] Preferably, the adjacent ends of two horizontally adjacent clamping plate members are respectively formed with a matching bayonet and a clamping strip. The clamping strip can be correspondingly clamped into the bayonet, so that the horizontally adjacent clamping plate members can be drawn closer to each other, and thus can be applicable to bottle stacks of different volumes.

[0023] To make the support of the support assembly more stable, preferably, at least a partial position of the outer periphery of the shelf has a horizontally extending positioning convex edge; the upper surface of the horizontally extending section of the support member can be abutted against the corresponding positioning convex edge up and down to support the positioning convex edge upward.

[0024] The lowermost support member is denoted as the lower support member, and the remaining support members are denoted as the upper support members; the lowermost shelf is denoted as the lower shelf, and the remaining shelves are denoted as the upper shelves; the lower shelf may be inclined due to uneven distribution of the bottle bodies, etc. At this time, the corresponding position of the lower support member may not be smoothly placed under the lower shelf. To ensure that the lower support member can smoothly support the lower shelf upward, preferably, the clamping and stacking components further include

[0025] an upper limit block, fixed on the inner bracket;

[0026] a lower limit block, fixed on the inner bracket;

[0027] a mounting shaft, fixed between the upper limit block and the lower limit block;

[0028] a movable block, sleeved on the mounting shaft in a vertically movable manner, and this movable block is fixed to the lower support member;

[0029] an elastic member, arranged between the movable block and the lower limit block, and having a tendency to support the movable block upward to make the lower support member support the lower shelf upward;

[0030] The support member has different states relative to the inner bracket:

[0031] In the first state, the lower support member supports the lower shelf upward, and the horizontally extending section of the upper support member is located below the positioning convex edge of the corresponding upper shelf and has a certain distance;

[0032] In the second state, the lateral extension segments of the upper support members move upward to abut against the corresponding upper shelves, thereby supporting the corresponding upper shelves and the bottles on that layer upward; under the action of the gravity of the lowermost layer of bottles and the elastic members, the lower support member continues to support the upper shelf upward, and the upper shelf tends to be in a laterally extended state.

[0033] Preferably, a bottle mouth clamping assembly is provided at the bottom of the inner bracket. The bottle mouth clamping assembly includes a bottle mouth clamping plate capable of moving in the inner and outer directions and a bottle mouth clamping plate driving member for driving the movement of the bottle mouth clamping plate. The main body of the bottle mouth clamping plate driving member is installed on the outer side of the inner bracket, and its power output shaft passes through the inner bracket to connect the bottle mouth clamping plate located on the inner side of the inner bracket. The bottle mouth clamping plate includes an inclined plate surface extending laterally, and this inclined plate surface slopes outward from top to bottom. Before the stacking device stacks the lifted bottle stack on another bottle stack, operate the bottle mouth clamping assembly to clamp the bottle mouths of the bottles on the top layer of another bottle stack, so that they can all be gathered under the lower shelf of the lifted bottle stack. Further, by providing the inclined plate surface, the bottles as a whole can be pushed inward and gathered, rather than just the bottle mouths being gathered.

[0034] Preferably, the stacking device includes four groups of the stack clamping assemblies, and the cross-section surrounded by the four inner brackets in the stack clamping state is rectangular.

[0035] Compared with the prior art, the present utility model is provided with a stack clamping assembly capable of lifting and lowering along a guide rail. The stack clamping assembly includes a bracket assembly, a support assembly, and a driving assembly. The outer bracket of the bracket assembly is fixed, and the inner bracket and the support assembly connecting the inner bracket can be driven under the action of the driving assembly, so that the stacking device can have a stack clamping state in which the support assemblies are relatively close to each other to support the shelf from below, and a disengaged state in which the support assemblies are relatively far away from each other and disengage from the shelf. When the stacking device is in the stack clamping state, the stack clamping assembly together with the bottle stack stably supported thereon is smoothly lifted along the guide rail, leaving space below for a trolley or other handling tools to easily place a new set of bottle stacks. Subsequently, the stack clamping assembly accurately moves downward along the guide rail under an instruction, and the bottle stack thereon is accurately stacked on top of the lower bottle stack to complete the stacking. Then, the stacking device is switched to the disengaged state to release the shelf. The whole process is smooth and efficient, greatly improving the level of mechanized operation, reducing the input and use of manpower, and at the same time ensuring the safety and efficiency of the operation.

[0050] The present utility model will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0051] As Figures 1 to 14 shown, it is a preferred embodiment of a stacking device for bottle bodies according to the present utility model. This embodiment includes a guide rail extending in the vertical direction and four groups of clamping stack assemblies 200. The guide rail adopts the prior art and will not be elaborated in this embodiment as long as it can ensure that the clamping stack assemblies 200 can move up and down along the guide rail. The number of the clamping stack assemblies 200 can be designed according to the actual situation. In this embodiment, taking the bottle stack 100 with a rectangular cross-section as an example, four groups of clamping stack assemblies 200 are adopted to correspond to the four sides of the rectangle.

[0052] The bottle stack 100 is placed on the base 300, and its placement structure can be referred to Figure 1 , including the shelf 120 and the bottle body 110. The shelf 120 is used to hold the bottle body 110 and divide the multiple bottle bodies 110 into multiple layers stacked on top of each other. In this embodiment, it is four layers. The shelf 120 is rectangular in this embodiment. The edges of three sides of its upper surface extend upward to form an upper edge 122 for blocking the bottle body 110. The upper edge 122 then extends horizontally to form a positioning convex edge 121. The side that does not extend the upper edge 122 becomes an opening for the bottle body 110 to enter, as Figure 6 shown. The bottom edge of the shelf 120 extends downward to form a lower edge 124 for blocking the bottle body 110. The lower edge 124 is annular, as Figure 7 shown. The top of each bottle body 110 is surrounded by the annulus formed by the lower edge 124.

[0053] The four groups of stacking components 200 in this embodiment cooperate with each other to achieve the function of lifting the bottle stack 100 and stacking it on another bottle stack 100. Each group of stacking components 200 includes main structures such as a bracket assembly 230, a support assembly 240, a drive assembly 250, a transmission assembly 260, a clamping plate assembly 270, and a bottle mouth clamping assembly 280, as Figure 2 shown.

[0054] The bracket assembly 230 includes an outer bracket 231 and an inner bracket 232. The outer bracket 231 is fixedly connected to the guide rail (not shown in the figure). The inner bracket 232 is closer to the shelf 120 for holding the bottle body 110 relative to the outer bracket 231. The support assembly 240 is connected to the inner bracket 232 and is used to support the shelf 120. The drive assembly 250 is installed on the outer bracket 231, and its power output shaft is connected to the transmission assembly 260 to drive the transmission assembly 260 to move. The transmission assembly 260 connects the drive assembly 250 and the inner bracket 232 and is used to drive the inner bracket 232 and the support assembly 240 to move. The clamping plate assembly 270 is connected to the inner bracket 232 and is used to clamp the bottle body 110 during stacking. The corresponding drive assembly 250 drives the corresponding transmission assembly 260 to move, indirectly driving the activities of the inner bracket 232, the support assembly 240, and the clamping plate assembly 270, so that the stacking device has a stacking state in which each support assembly 240 moves relatively closer to support the shelf 120 from below, and a disengaged state in which each support assembly 240 moves relatively farther away from the shelf 120.

[0055] There are various optional structures for how the driving component 250 drives the inner support 232. Considering the smoothness and precision of driving, each stack clamping component 200 includes at least one set of transmission components 260. Each set of transmission components 260 includes a first transmission rod 261 and a second transmission rod 262. A rotating shaft 263 is disposed through the middle parts of the first transmission rod 261 and the second transmission rod 262. The first transmission rod 261 and the second transmission rod 262 can rotate around the rotating shaft 263, as Figure 12 shown. Then please refer to Figure 9 and Figure 10 . The upper end of the first transmission rod 261 is rotatably connected to the upper part of the outer support 231 relative to the outer support 231, and the lower end of the first transmission rod 261 is rotatably connected to the lower part of the inner support 232 relative to the inner support 232; the lower end of the second transmission rod 262 is rotatably connected to the lower part of the outer support 231 relative to the outer support 231, and the upper end of the second transmission rod 262 is rotatably connected to the upper part of the inner support 232 relative to the inner support 232.

[0056] In order to enable the entire inner support 232 to move horizontally smoothly and synchronously under the driving action, in this embodiment, each stack clamping component 200 is provided with two sets of transmission components 260. Referring to Figure 9 and Figure 10 , a first outer connecting rod 264 connects the outer ends of the first transmission rods 261 of one set of transmission components 260 and the outer ends of the first transmission rods 261 of the other set of transmission components 260; a first inner connecting rod 265 connects the inner ends of the first transmission rods 261 of one set of transmission components 260 and the inner ends of the first transmission rods 261 of the other set of transmission components 260; a second outer connecting rod 266 connects the outer ends of the second transmission rods 262 of one set of transmission components 260 and the outer ends of the second transmission rods 262 of the other set of transmission components 260; a second inner connecting rod 267 connects the inner ends of the second transmission rods 262 of one set of transmission components 260 and the inner ends of the second transmission rods 262 of the other set of transmission components 260; sliding grooves 233 are provided at the lower parts of the outer support 231 and the inner support 232. The lower ends of the second outer connecting rod 266 and the second inner connecting rod 267 are respectively disposed in the corresponding sliding grooves 233, so that they can slide vertically relative to the respective connected supports, thereby driving the inner support 232 to only move horizontally without changing in the vertical height; the driving component 250 selects two cylinders 251 arranged in parallel. A connecting sleeve 253 is provided at the end of the piston 252 of the cylinder 251. The connecting sleeve 253 is sleeved outside the second outer connecting rod 266 to support the second outer connecting rod 266. The second outer connecting rod 266 can rotate relative to the connecting sleeve 253. When the piston 252 expands and contracts, the second outer connecting rod 266 moves up and down with it.

[0057] To prevent the bottle body 110 from being crushed, it is necessary for the support assembly 240 to support each shelf 120 independently. Therefore, in this embodiment, each support assembly 240 is provided with four support members 241 corresponding to four shelves 120. Each support member 241 includes a laterally extending section 242. The upper surface of the laterally extending section 242 of the support member 241 can abut against the positioning convex edge 121 of the corresponding shelf 120 up and down to support the positioning convex edge 121 upward, as Figure 8 shown. In addition to the laterally extending section 242, the support member 241 also has a vertically extending section. In this embodiment, the lowermost support member 241 is denoted as the lower support member 241a, and the lower support member 241a is in an inverted L shape. The remaining support members 241 are denoted as the upper support members 241b, which are in a positive L shape. Refer to Figure 9 . The lowermost shelf 120 is denoted as the lower shelf 120a, and the remaining shelves 120 are denoted as the upper shelves 120b.

[0058] The lower shelf 120a may tilt due to uneven distribution of the bottle bodies 110 or other reasons. At this time, it may be impossible to smoothly place the corresponding position of the lower support member 241a under the lower shelf 120a. To ensure that the lower support member 241a can smoothly support the lower shelf 120a upward, the stacking assembly 200 further includes an upper limit block 234 fixed on the inner support 232, a lower limit block 235 fixed on the inner support 232, and a mounting shaft 236 fixed between the upper limit block 234 and the lower limit block 235. A movable block 237 is sleeved outside the mounting shaft 236 in a vertically movable manner, and the movable block 237 is fixed to the lower support member 241a. An elastic member 238 is disposed between the movable block 237 and the lower limit block 235, and has a tendency to support the movable block 237 upward so that the lower support member 241a supports the lower shelf 120a upward. Refer to Figure 14 .

[0059] The support member 241 has different states relative to the inner support 232: In the first state, the lower support member 241a supports the lower shelf 120a upward, and the laterally extending section 242 of the upper support member 241b is located below the positioning convex edge 121 of the corresponding upper shelf 120b and has a certain distance; In the second state, the laterally extending sections 242 of the upper support members 241b move upward to abut against the corresponding upper shelves 120b, and support the corresponding upper shelves 120b and the bottle bodies 110 of this layer upward; Under the action of the gravity of the lowermost bottle bodies 110 and the elastic member 238, the lower support member 241a continues to support the upper shelf 120b upward, and the upper shelf 120b tends to be in a laterally extended state.

[0060] In order to prevent the bottles 110 from being arranged in disorder or even falling off the shelf 120 during the stacking process, each group of clamping and stacking assemblies 200 of the present embodiment further includes a clamping plate assembly 270 installed on the inner side of the inner bracket 232. Each group of clamping plate assembly 270 includes four clamping plate members 271. A clamping plate member 271 is correspondingly arranged above each support member 241. The clamping plate member 271 is in the shape of a transversely extending plate and has a vertically extending surface for contacting the outer side wall of the bottle body 110, so as to clamp the outer side wall of the bottle during stacking. The adjacent ends of two transversely adjacent clamping plate members 271 are respectively formed with matching clamping ports 273 and clamping strips 272, such as Figure 8 As shown, the clamping strips 272 can be correspondingly clamped into the clamping openings 273 , so that the laterally adjacent clamping plate members 271 can be retracted inwards more closely, thereby being suitable for bottle pallets 100 of different volumes.

[0061] The bottom of the inner bracket of this embodiment is provided with a bottle-holding assembly 280. The bottle-holding assembly 280 includes a bottle-holding plate 281 that can move in the inner and outer directions and a bottle-holding plate driving member 282 that drives the bottle-holding plate 281 to move. The main body of the bottle-holding plate driving member 282 is installed on the outer side of the inner bracket 232, and its power output shaft passes through the inner bracket 232 and is connected to the bottle-holding plate 281 located on the inner side of the inner bracket 232, as shown in FIG. Figure 9 As shown. The bottle mouth clamping plate 281 includes a transversely extending inclined plate surface, which is inclined outward from top to bottom, and the upper edge of the inclined plate surface extends outward to form a horizontal plate surface, which is used to strengthen the overall strength of the bottle mouth clamping plate 281. Before stacking the lifted bottle stack 100 on another bottle stack 100 in this embodiment, the bottle mouth clamping assembly 280 is operated to clamp the bottle mouths of the topmost bottle bodies 110 of the other bottle stack 100, so that they can all be folded in the annular lower rib 124 of the lower shelf 120a of the lifted bottle stack 100. Furthermore, by setting the inclined plate surface, the bottle bodies 110 can be pushed inward as a whole and gathered together, rather than just the bottle mouths being folded together.

[0062] The working principle of this embodiment:

[0063] In this embodiment, the support components 240 are relatively close to each other and support the shelf 120 from below. Figure 4 and Figure 5 , and the disengagement state of each support assembly 240 being relatively far away from the shelf 120, refer to Figure 2 and Figure 3。First, place the bottle stack 100 directly below this embodiment. Control the clamping stack assembly 200 in the disengaged state to move downward along the guide rail until it is located outside the bottle stack 100. Each shelf 120 to be lifted corresponds to a support member 241 with a height adapted to it. Then, control the piston 252 of the air cylinder 251 to contract upward. The second outer connecting rod 266 follows the piston 252 to rise under the action of the connecting sleeve 253. The rise of the second outer connecting rod 266 will drive other transmission rods and connecting rods to move together. The second outer connecting rod 266 and the second inner connecting rod 267 slide up and down in the chute 233, so the inner bracket 232 will not have a vertical displacement, but will only be pushed inward under the transmission action. As the four inner brackets 232 come closer, each support member 241 extends under the corresponding shelf 120, and this embodiment changes to the clamping stack state. Then, operate the motor to smoothly lift the clamping stack assembly 200 together with the bottle stack 100 it stably supports along the guide rail, leaving space below to facilitate the easy placement of a new set of bottle stacks 100 by a trolley or other handling tools. Subsequently, the clamping stack assembly 200 accurately moves downward along the guide rail to the same height as the mouths of the bottle bodies 110 on the top layer of the new set of bottle stacks 100. Operate the bottle mouth clamping plate driving member 282 to drive the bottle mouth clamping plate 281 to push the mouths of these bottle bodies 110 inward to make them close. Then, the clamping stack assembly 200 continues to move downward, and the bottle stack 100 on it is accurately stacked on top of the lower bottle stack 100 to complete the stacking. Then, the piston 252 of the air cylinder 251 extends downward, and the inner bracket 232 retracts outward. This embodiment switches to the disengaged state, releasing the shelf 120. The whole process is smooth and efficient, greatly improving the level of automated operation, and at the same time ensuring the safety and efficiency of the operation.
