Description

Technical Field

[0001] The utility model relates to the technical field of cartoning machinery and equipment, in particular to an automatic carton feeding machine for a high-speed cartoning machine. Background Art

[0002] The packaging automation industry is developing rapidly. As an important part of the packaging production line, the cartoning machine has been increasing its packaging speed. At the time of patent CN207809927U, the speed was still 450 boxes per minute, but now it has achieved a packaging speed of 600 boxes or even higher.

[0003] The silo for storing paper boxes is installed on the cartoning machine. Due to the layout of the cartoning machine, the silo cannot be extended indefinitely, resulting in limited capacity for storing boxes, which limits the improvement of cartoning speed.

[0004] Most existing silos are 1.5-2m long and can store 800-1000 cartons. If calculated based on a packaging speed of 600 cartons per minute, the speed of manual stacking is actually 2-3 times the speed of carton consumption. However, due to the limited capacity of the silo, the time required to consume a silo is short. To avoid material shortage, a worker is required to be on duty next to each silo to stack cartons into the silo continuously, which results in the workers not being able to be free and wastes human resources. Utility Model Content

[0005] The utility model aims to provide an automatic carton feeding machine for a high-speed cartoning machine, so as to solve the technical problems in the prior art that the capacity of a silo is limited, the time required to consume a silo is short, a worker is required to be on duty next to each silo, and paper boxes are continuously stacked into the silo, resulting in the workers being unable to be liberated and wasting human resources.

[0006] In order to solve the above technical problems, the utility model specifically provides an automatic box feeding machine for a high-speed box packing machine, including a buffer mechanism, a stacking platform, a transfer platform and a box pushing mechanism;

[0007] The stacking platform is used for stacking and storing paper boxes, and a plurality of stacking platforms are installed on the buffer mechanism;

[0010] The box pushing mechanism is arranged above the transfer platform, and is used for pushing the paper box on the stacking platform close to and flush with the transfer platform onto the transfer platform, and pushing the paper box along the transfer platform into the cartoning machine.

[0011] As a preferred solution of the utility model, the buffer mechanism is installed and connected with the stacking platform through a connecting rod and a double wheel groove mechanism, so that the stacking platform always remains horizontal during the rotation process.

[0012] As a preferred solution of the utility model, a baffle assembly is provided on the stacking platform to reduce the probability of the paper box falling during the rotation process.

[0013] As a preferred solution of the utility model, the baffle assembly includes a rear baffle, a left baffle and a right baffle;

[0014] The two ends of the rear baffle are rotatably connected to the two ends of the stacking platform so that the rear baffle can be turned over on the stacking platform;

[0015] When the stacking platform rotates to a position close to the carton stacking area, the rear baffle is located on a side close to the transfer platform to facilitate stacking of carton boxes;

[0016] When the stacking platform rotates to the vicinity of the transfer platform, the robot installed on one side of the transfer platform can flip the rear baffle to the side away from the transfer platform, so that the box pushing mechanism can transfer the paper box to the transfer platform.

[0017] As a preferred solution of the utility model, the box pushing mechanism includes a box pushing plate and a displacement assembly, and the box pushing plate is fixedly mounted on the displacement assembly;

[0018] The displacement assembly can drive the box-pushing plate to move on the x-axis, y-axis and z-axis;

[0019] When the rear baffle is located at a side away from the transfer platform, there is a gap between the rear baffle and the paper box for the box pushing plate to be inserted.

[0020] As a preferred solution of the utility model, the box pushing plate is configured as a U-shaped plate to reduce the probability of the paper box falling during the transfer process.

[0021] As a preferred solution of the utility model, the left baffle and the right baffle are both configured as three-petal baffles, the three petals are evenly distributed on the circumference, and the center of the circle is connected to the stacking platform via a damping shaft;

[0022] The two three-petal baffles are located between the two ends of the box-pushing plate, so that when the box-pushing plate pushes the paper box to leave the stacking platform, the three-petal baffles can be driven to rotate synchronously;

[0023] The lateral distance between the rear baffle and the center of the three-petal baffle is smaller than the radius of the three-petal baffle, so that the three-petal baffle can drive the rear baffle to flip to the side close to the transfer platform when rotating.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] The utility model specifically provides an automatic box feeding machine for a high-speed box packing machine, comprising a buffer mechanism 1, a stacking platform 2, a transfer platform 3 and a box pushing mechanism 4;

[0042] The stacking platform 2 is used for stacking and storing paper boxes, and a plurality of stacking platforms are installed on the buffer mechanism 1;

[0043] The buffer mechanism 1 is used to drive the multiple stacking platforms 2 to rotate cyclically in a vertical plane, and can keep the stacking platforms 2 always horizontal during the rotation process;

[0044] Two opposite sides of the buffer mechanism 1 are respectively set as a carton transfer area and a carton stacking area for placing cartons on the stacking platform 2, and the transfer platform 3 is horizontally arranged in the carton transfer area, and one end of the transfer platform 3 extends into the cartoning machine 5;

[0045] The box pushing mechanism 4 is arranged above the transfer platform 3 , and is used to push the paper boxes on the stacking platform 2 close to and flush with the transfer platform 3 onto the transfer platform 3 , and push the paper boxes along the transfer platform 3 into the cartoning machine 5 .

[0046] The working principle of the automatic box feeding machine is as follows:

[0047] The buffer mechanism 1 drives the stacking platform 2 to rotate in a circular motion in the vertical direction. Workers stand in the carton stacking area and quickly stack the cartons on the stacking platforms 2 one by one. The box pushing mechanism 4 can push the cartons on the stacking platform 2 (the stacking platform 2 that is flush with and adjacent to the transfer platform 3 at the time) to the transfer platform 3, and then push the cartons along the transfer platform 3 into the cartoning machine 5.

[0048] The automatic carton feeding machine is configured with a plurality of stacking platforms 2 on a buffer mechanism 1, and the buffer mechanism 1 drives the stacking platforms 2 to rotate in a circular manner. Not only does it occupy a small area, but workers can also stack cartons on a plurality of stacking platforms 2 at one time as the stacking platforms 2 rotate (the rotation speed of the buffer mechanism 1 is controllable, and the rotation speed can be increased when stacking cartons, and can be decreased after stacking to adapt to the speed of manual stacking of cartons and the speed of consumption of cartons by the cartoning machine 5). The cartoning machine 5 needs a longer time to completely consume the cartons on the plurality of stacking platforms 2.

[0049] That is, the time from when the workers fill all the stacking platforms 2 with cartons to when all the cartons on the stacking platforms 2 are consumed is greatly extended, freeing the workers from having to guard a machine all the time. During this period, the workers can do other work, or one person can replenish materials for multiple automatic box feeding machines, thereby improving work efficiency and making full use of manpower.

[0050] For example, each buffer mechanism 1 is equipped with 8 stacking platforms 2, each stacking platform 2 can stack 800 cartons, and a worker can stack 2 platforms per minute, and it takes 4 minutes to stack all 8 platforms. However, the cartoning machine 5 consumes 600 cartons per minute, and it takes at least 10 minutes to consume all cartons, resulting in a 6-minute time gap.

[0051] Furthermore, the buffer mechanism 1 is installed and connected to the stacking platform 2 through a connecting rod and a double wheel groove mechanism 6, so that the stacking platform 2 always remains horizontal during the rotation process.

[0052] Furthermore, a baffle assembly is provided on the stacking platform 2 to reduce the probability of the paper boxes falling during the rotation process.

[0053] The baffle assembly provides the following two implementations:

[0054] The first embodiment of the baffle assembly:

[0055] The baffle assembly is provided with a U-shaped baffle, which is fixedly mounted on the stacking platform 2, and the U-shaped opening of the baffle assembly faces away from the carton stacking area. When stacking cartons, a gap needs to be left between the carton and the U-shaped baffle to facilitate the insertion of the execution component of the box pushing mechanism 4 to push the carton from the stacking platform 2 to the transfer platform 3.

[0056] The second embodiment of the baffle assembly:

[0057] The baffle assembly includes a rear baffle 7, a left baffle and a right baffle;

[0058] The two ends of the rear baffle 7 are rotatably connected to the two ends of the stacking platform 2, so that the rear baffle 7 can be turned over on the stacking platform 2;

[0059] When the stacking platform 2 rotates to the side close to the carton stacking area, the rear baffle 7 is located on the side close to the transfer platform 3, so that the workers can stack the cartons on the stacking platform 2 in the carton stacking area. At the same time, the cartons can be stacked against the rear baffle 7, so that the cartons can be stacked more neatly.

[0060] When the stacking platform 2 rotates to the vicinity of the transfer platform 3, the robot installed on one side of the transfer platform 3 can flip the rear baffle 7 to the side away from the transfer platform 3 to avoid the rear baffle 7 being blocked between the stacking platform 2 and the transfer platform 3, so that the box pushing mechanism 4 can transfer the paper box to the transfer platform 3.

[0061] The manipulator can be configured as a device such as a cylinder, an electromagnetic push rod, a servo push rod, a motor, etc. that can linearly push the baffle or rotationally drive the baffle.

[0062] like Figure 6 As shown, if a motor is used (the motor is not shown), a force block can be set at the end of the rear baffle 7, and the motor drives the rocker to rotate, and the rocker hits the force block to flip the rear baffle 7 to the side away from the transfer platform 3.

[0063] The rear motor drives the rocker to reset, and the stacking platform 2 (the stacking platform 2 after the rear baffle 7 is turned over) continues to rotate and approaches the transfer platform 3.

[0064] That is, only one motor is used to flip over the tailgates 7 on all the stacking platforms 2 .

[0065] Furthermore, the box pushing mechanism 4 includes a box pushing plate 8 and a displacement assembly, and the box pushing plate 8 is fixedly mounted on the displacement assembly;

[0066] The displacement assembly can drive the box-pushing plate 8 to move on the x-axis, y-axis and z-axis;

[0067] When the rear baffle 7 is located at a side away from the transfer platform 3, there is a gap between the rear baffle 7 and the paper box for the box pusher plate 8 to be inserted.

[0068] Specifically, since the paper boxes are initially stacked against the rear baffle 7, the flipping center of the rear baffle 7 is set to deviate from the center line of the paper boxes, that is, the flipping center line of the rear baffle 7 is farther away from the transfer platform 3 relative to the center line of the paper boxes, so that when the rear baffle 7 is flipped to the side away from the transfer platform 3, there is a gap between the rear baffle 7 and the paper boxes for the box push plate 8 to be inserted.

[0069] Furthermore, the box pushing plate 8 is configured as a U-shaped plate, so that the box pushing plate 8 has the ability to push the carton from the stacking platform 2 to the transfer platform 3 , and push the carton along the transfer platform 3 into the cartoning machine 5 .

[0070] At the same time, it can also prevent the cartons at the end from falling when the cartons are pushed from the stacking platform 2 to the transfer platform 3; and prevent the cartons from falling from the side where the rear baffle 7 is located when the cartons are pushed into the cartoning machine 5 along the transfer platform 3.

[0071] Furthermore, the left baffle and the right baffle are both configured as three-petal baffles 9, the three petals are evenly distributed around the circumference, and the center of the circle is connected to the stacking platform 2 via a damping shaft, and the damping connection can prevent the baffle from rotating uncontrollably;

[0072] The two three-petal baffles 9 are located between the two ends of the box-pushing plate 8, so that when the box-pushing plate 8 pushes the carton to leave the stacking platform 2, the three-petal baffles 9 can be driven to rotate synchronously; at the same time, the box-pushing plate 8 can also hold the carton from the rear, left and right sides;

[0073] The lateral distance between the center of the rear baffle 7 and the three-petal baffle 9 is smaller than the radius of the three-petal baffle 9, so that the three-petal baffle 9 can drive the rear baffle 7 to flip to the side close to the transfer platform 3 when rotating, and the automatic flipping and resetting of the rear baffle 7 can be achieved without the need for an additional driving mechanism.

[0074] Further, the displacement assembly includes a z-axis cylinder assembly 10, a y-axis cylinder assembly 11 and an x-axis synchronous belt slide assembly 12;

[0075] The box push plate 8 is fixedly mounted on the z-axis cylinder assembly 10 , the z-axis cylinder assembly 10 is mounted on the y-axis cylinder assembly 11 , and the y-axis cylinder assembly 11 is mounted on the x-axis synchronous belt slide assembly 12 .

[0076] Taking the transfer of a packaging box to the cartoning machine 5 as an example, the working logic of the displacement component is explained:

[0077] First, the y-axis cylinder assembly 11 pushes the z-axis cylinder assembly 10 to move above the stacking platform 2 (to prevent the box pushing plate 8 from interfering with the rotation of the stacking platform 2, when the carton is not being transferred, the box pushing plate 8 needs to be away from the stacking platform 2, generally located above the transfer platform 3), and then the z-axis cylinder assembly 10 pushes the box pushing plate 8 downward, so that the box pushing plate 8 enters the gap between the carton and the rear baffle 7, and then the y-axis cylinder assembly 11 pushes the z-axis cylinder assembly 10 and the box pushing plate 8 to move toward the transfer platform 3, transferring the carton from the stacking platform 2 to the transfer platform 3, and finally the x-axis synchronous belt slide assembly 12 drives the y-axis cylinder assembly 11, the z-axis cylinder assembly 10 and the box pushing plate 8 to move toward the cartoning machine 5, and sends the carton into the cartoning machine 5.

[0078] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
