Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for canned food production, specifically to a canned food palletizing machine. Background Technology

[0002] Can palletizing machines are equipment used to stack canned goods. Stacked cans make better use of space, making it easier to pack and handle them in subsequent processes. They can effectively reduce transportation difficulties and costs, playing a vital role in the canned goods processing and production process.

[0003] In the existing technology, metal cans are the most widely used containers, so there are many machines on the market for palletizing metal cans. The most common method is to use electromagnets to move and stack the metal cans. However, existing can palletizing machines have the following design flaws: First, the suction cup mechanism is usually driven by a multi-axis drive mechanism or a robotic arm. The movement of the multi-axis drive mechanism is slow and it is difficult to quickly perform multi-layer stacking operations. The robotic arm requires a special program and is too expensive, which causes certain inconveniences in the actual production process. Utility Model Content

[0004] The purpose of this utility model is to provide a can palletizing machine to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a can palletizing machine, including a frame body. The frame body is equipped with an upper and lower drive mechanism, and the upper and lower drive mechanism is combined with a front and rear drive mechanism to set up a can suction cup mechanism. The upper and lower drive mechanism and the front and rear drive mechanism can independently drive the can suction cup mechanism to complete the suction, lifting, translation and lowering of cans for palletizing. A mobile conveyor belt mechanism is provided on the side of the frame body, and a collection conveyor belt mechanism is connected to the end of the mobile conveyor belt mechanism. A can-pressing blocking mechanism is provided between the collection conveyor belt mechanism and the mobile conveyor belt mechanism. This mechanism is used to transport multiple rows of cans forward synchronously with the help of the collection conveyor belt mechanism. At the same time, the can-pressing blocking mechanism restricts the multiple rows of cans to a flat array state before releasing them to the mobile conveyor belt mechanism for forward transport in a parallel manner.

[0006] Preferably, the can suction cup mechanism includes a bracket and a magnetic suction cup. The magnetic suction cup is fixedly mounted on the bracket via a suction cup mounting bracket, and the magnetic suction cup is placed flat below the bracket. Shock absorbers are installed at the corners of the bracket, and the lower part of each shock absorber is connected to the magnetic suction cup to provide cushioning protection in the descent direction after the magnetic suction cup descends to magnetically fix the can.

[0007] Preferably, the magnetic chuck is a rectangular electromagnet chuck structure, and the shock absorber is a spring shock absorber.

[0008] Preferably, the up-and-down drive mechanism includes a drive motor and a transmission sprocket pair. The drive motor and the transmission sprocket pair are mounted on the top of the frame body, and the drive motor and the transmission sprocket pair are connected together via a transmission shaft. The transmission sprocket pair has chains placed at the corners of the frame body, and the lower end of the chain of the transmission sprocket pair is connected to the front and rear drive mechanism, so as to drive the front and rear drive mechanism and the can suction cup mechanism to move up and down together with the help of the up-and-down drive mechanism.

[0009] Preferably, vertical moving guide rails are installed at the corners of the frame body, and vertical moving sliders are linearly slidably installed on the vertical moving guide rails. The vertical moving sliders are connected to the front and rear drive mechanisms, so as to guide and prevent the lifting and lowering movements of the front and rear drive mechanisms and the can suction cup mechanism by the linear sliding of the vertical moving sliders along the vertical moving guide rails.

[0010] Preferably, the front and rear drive mechanism includes front and rear moving guide rails and front and rear travel rollers. The front and rear moving guide rails are both horizontally positioned at the front and rear of the frame body, and each of the front and rear moving guide rails is horizontally positioned and connected to the chain at the corresponding corner position, so as to drive the front and rear moving guide rails to perform lifting and lowering actions through the chain. Each front and rear moving guide rail is linearly rolled with a number of front and rear travel rollers, and each of the front and rear travel rollers is connected to the bracket. At the same time, a translation drive component is assembled and installed at the lower part of the front and rear moving guide rails, so as to drive the can suction cup mechanism to perform translational operation through the translation drive component, and guide and prevent deviation by the front and rear travel rollers rolling linearly along the front and rear moving guide rails.

[0011] Preferably, the translation drive component is a lead screw and nut pair mechanism driven by a servo motor.

[0012] Preferably, the collecting conveyor belt mechanism is a multi-row track-type conveyor belt.

[0013] Preferably, the moving conveyor belt mechanism is a plate conveyor belt.

[0014] Preferably, the pressure tank blocking mechanism is driven by a pneumatic lifting mechanism.

[0015] In practical production, the aforementioned can palletizing machine features an independent up-and-down drive mechanism and a front-and-back drive mechanism to independently drive the can suction cup mechanism for lifting, translating, and lowering the cans. This ensures that the can suction cup mechanism does not interfere with each other's movements, improving palletizing efficiency. Compared to multi-axis drive mechanisms, it achieves higher palletizing efficiency, and compared to robotic arms, it reduces investment costs and implementation difficulty. Furthermore, the machine includes a collecting conveyor belt mechanism and a moving conveyor belt mechanism, with a can-pressing and blocking mechanism between them. The collecting conveyor belt mechanism allows for the synchronous forward transport of multiple rows of cans, while the can-pressing and blocking mechanism restricts the movement of multiple rows of cans. After being aligned in a flat array, the cans are released to the moving conveyor belt mechanism for forward transport in a parallel manner. This achieves the alignment and arrangement of the can transport, facilitating the simultaneous lifting and suction of multiple rows of cans from below the can suction cup mechanism. It also allows for the flat array of cans to be placed onto the pallet for stacking, further improving stacking efficiency. Furthermore, the can suction cup mechanism, with its magnetic suction cups, can stably and magnetically hold the flat array of cans in place. The magnetic attachment can be quickly released when the magnetic suction cups are de-energized. The magnetic attachment and release methods are simple and easy to implement, facilitating the movement of the flat array of cans on the moving conveyor belt mechanism to the pallet for descent, and allowing for timely release once the cans reach the stacking height to complete the stacking process.

[0016] The beneficial effects are as follows: 1. This utility model is equipped with an up-and-down drive mechanism and a front-and-back drive mechanism to independently drive the can suction cup mechanism to lift and move the cans up and down and to place them on the pallet, thus ensuring that the actions of the can suction cup mechanism will not interfere with each other, which helps to improve the palletizing efficiency of the cans. At the same time, it can achieve higher palletizing efficiency than using a multi-axis drive mechanism, and can reduce investment costs and implementation difficulty compared to using a robotic arm. 2. The system is equipped with a collection conveyor belt mechanism and a moving conveyor belt mechanism, with a can-pressing and blocking mechanism between them. This allows the collection conveyor belt mechanism to simultaneously transport multiple rows of cans forward, while the can-pressing and blocking mechanism can restrict the multiple rows of cans to a flat array before releasing them to the moving conveyor belt mechanism for parallel transport. This achieves even and organized can transport, making it easier for multiple rows of cans to be lifted and pulled up by the can suction cup mechanism below them, and also facilitating the flat array of cans to be placed on a pallet for stacking and palletizing, thereby further improving palletizing efficiency. 3. Equipped with a can suction cup mechanism, the magnetic suction cups of the can suction cup mechanism can stably and magnetically fix multiple rows of cans arranged in a flat array below by means of electromagnetic attraction. At the same time, the magnetic fixation of the cans can be quickly released by means of power failure of the magnetic suction cups. The magnetic fixation and release of the cans is simple and easy to implement. It is convenient to move multiple rows of cans arranged in a flat array on the moving conveyor belt to the tray and then drop them. At the same time, it is convenient to release them in time after the cans fall to the stacking height to complete the stacking. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] See Figures 1-3 As shown, this utility model provides a can palletizing machine. The frame body 2 is equipped with an upper and lower drive mechanism 1, and the upper and lower drive mechanism 1 is combined with a can suction cup mechanism 3 through a front and rear drive mechanism 4. The upper and lower drive mechanism 1 and the front and rear drive mechanism 4 can independently drive the can suction cup mechanism 3 to complete the suction, lifting, translation and lowering of cans for palletizing. Specifically, the upper and lower drive mechanism 1 includes a drive motor 102 and a transmission sprocket pair 101. The drive motor 102 and the transmission sprocket pair 101 are combined and installed on the top of the frame body 2. The drive motor 102 and the transmission sprocket pair 101 are connected together by a transmission shaft 104. The transmission sprocket pair 101 has chains 103 at the corners of the frame body 2. The lower end of the chains 103 of the transmission sprocket pair 101 is connected to the front and rear drive mechanism 4. The purpose of this arrangement is to use the upper and lower drive mechanism 1 to drive the front and rear drive mechanism 4 and the can suction cup mechanism 3 to move up and down together.

[0022] See Figures 1-3 As shown, the front and rear drive mechanism 4 includes front and rear moving guide rails 402 and front and rear travel rollers 401. The front and rear moving guide rails 402 are both horizontally placed at the front and rear positions of the frame body 2. The front and rear moving guide rails 402 are both horizontally arranged and connected to the chains 103 at the corresponding corner positions, so as to drive the front and rear moving guide rails 402 to perform lifting and lowering actions through the chains 103. Several front and rear travel rollers 401 are linearly rolled on the front and rear moving guide rails 402, and the front and rear travel rollers 401 are all connected to the bracket 303. At the same time, a translation drive component 403 is assembled and installed at the lower part of the front and rear moving guide rails 402. The purpose of this arrangement is to drive the can suction cup mechanism 3 to move horizontally through the translation drive component 403 and guide and prevent deviation by the linear rolling of the front and rear travel rollers 401 along the front and rear moving guide rails 402.

[0023] See Figure 1As shown, the can suction cup mechanism 3 includes a bracket 303 and a magnetic suction cup 302. The magnetic suction cup 302 is fixedly mounted on the bracket 303 via a suction cup mounting bracket 304, and the magnetic suction cup 302 is placed flat below the bracket 303. Buffer shock absorbers 301 are installed at the corners of the bracket 303, and the lower part of each buffer shock absorber 301 is connected to the magnetic suction cup 302. This buffer shock absorber 301 is used to buffer and protect the cans in the descent direction after the magnetic suction cup 302 descends to magnetically fix the cans. The reason for this design is that the magnetic suction cup 302 of the can suction cup mechanism 3 can stably magnetically fix multiple rows of cans arranged in a flat array below by means of electromagnetic attraction. At the same time, the magnetic suction cup 302 can be quickly deactivated by means of power failure, making the magnetic fixation and deactivation of the cans simple and easy to implement.

[0024] See Figures 1-3 As shown, a mobile conveyor belt mechanism 5 is provided on the side of the frame body 2, and a collection conveyor belt mechanism 7 is provided at the end of the mobile conveyor belt mechanism 5. A can-pressing blocking mechanism 6 is provided between the collection conveyor belt mechanism 7 and the mobile conveyor belt mechanism 5. The effect of this arrangement is that the collection conveyor belt mechanism 7 can transport multiple rows of cans forward synchronously, while the can-pressing blocking mechanism 6 can block and restrict the multiple rows of cans to a flat array state before releasing them to the mobile conveyor belt mechanism 5 for forward transport in a parallel manner.

[0025] See Figures 1-3 As shown, the following optimizations have been made to this application. Specifically, the magnetic chuck 302 is a rectangular electromagnet chuck 302 structure, and the shock absorber 301 is a spring shock absorber, so that the selection of both the magnetic chuck 302 and the shock absorber 301 can meet the design requirements and be easily procured. Furthermore, vertically mounted vertical moving guide rails 105 are installed at the corners of the frame body 2, and vertically sliding sliders 106 are linearly mounted on the vertical moving guide rails 105. The vertically sliding sliders 106 are connected to the front and rear drive mechanisms 4. With this configuration, the lifting and lowering movements of the front and rear drive mechanisms 4 and the can suction cup mechanism 3 are guided and prevented from deviating by the linear sliding of the vertically sliding sliders 106 along the vertical moving guide rails 105.

[0026] See Figures 1-3As shown, the translation drive component 403 is a lead screw and nut pair mechanism driven by a servo motor, which enables the translation drive component 403 to stably and sensitively drive the can suction cup mechanism 3 to perform translational operations. Optionally, the collecting conveyor belt mechanism 7 is a multi-row parallel track-type conveyor belt, which allows for the simultaneous side-by-side transport of multiple rows of cans. Furthermore, the moving conveyor belt mechanism 5 is a plate conveyor belt, which allows for the transport of multiple rows of aligned cans forward in a parallel manner. Even further, the pressure can blocking mechanism 6 is driven by a pneumatic lifting mechanism, which allows for repeated lifting and lowering using a pneumatic drive.

[0027] With the above structure, in actual production, the vertical drive mechanism 1 and the front-back drive mechanism 4 independently drive the can suction cup mechanism 3 to lift and move vertically and horizontally, respectively. This allows the can suction cup mechanism 3 to independently perform the suction, lifting, horizontal movement, and lowering of cans, ensuring that the movements of the can suction cup mechanism 3 do not interfere with each other. This helps improve the palletizing efficiency of cans. Compared with using a multi-axis drive mechanism, it can achieve higher palletizing efficiency. Compared with using a robotic arm, it reduces investment costs and implementation difficulty. Furthermore, the presence of a collecting conveyor belt mechanism 7 and a moving conveyor belt mechanism 5, with a can-pressing and blocking mechanism 6 between them, allows the collecting conveyor belt mechanism 7 to synchronously transport multiple rows of cans forward, while the can-pressing and blocking mechanism 6 can restrict the multiple rows of cans to a flush array. The cans are then released to the mobile conveyor belt 5 for parallel transport, achieving even alignment of the cans during transport. This facilitates the simultaneous transport of multiple rows of cans to the can suction cup mechanism 3, which then lifts and raises them. It also allows the cans to be stacked on a pallet in a parallel array, further improving stacking efficiency. Furthermore, the can suction cup mechanism 3 uses its magnetic suction cups 302 to magnetically hold the parallel array of cans in place. The magnetic suction cups 302 can be de-energized to quickly release the cans. The magnetic fixing and unfixing methods are simple and easy to implement. This allows the parallel array of cans on the mobile conveyor belt 5 to be magnetically fixed and moved above the pallet before falling, and also facilitates timely release once the cans reach the stacking height to complete the stacking process.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
