Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical technology and relates to a stacking machine, particularly a palletizing head assembly of a throwing-type automatic stacking machine. Background Technology
[0002] When bagged and boxed materials (such as flour, grain and oil, building materials, fertilizers, cement, feed, plastics, coal, chemicals, battery materials, dyes and pigments, food and other industries) are packed and loaded onto trucks, manual handling is usually used, which is time-consuming, labor-intensive and inefficient. Although there are some automated loading devices, the conveying can only be done in one direction and the conveying direction cannot be changed at will, so the loading of the whole truck still needs to be done manually. The accuracy of the transfer is low, the speed is slow and the reliability is poor. Therefore, people invented automatic packing machines.
[0003] For example, a novel stacking and unloading machine disclosed in Chinese patent literature (application number: 202420771277.3) includes a frame, a translation frame on the frame, and a drive mechanism that can drive the translation frame to move horizontally and reciprocally. The translation frame is equipped with a bag-flipping mechanism, which includes a rotating frame axially fixed to the translation frame and a motor that drives the rotating frame to rotate. The rotating frame is equipped with a horizontally arranged material trough. However, this novel stacking and unloading machine can only throw and stack bags in one direction and cannot throw and stack bags in multiple directions and at multiple angles. Therefore, its application range is small and its stacking efficiency is low. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a palletizer head assembly for an automatic stacking machine that can adjust the throwing direction and achieve accurate and efficient stacking.
[0005] The objective of this utility model can be achieved through the following technical solution: a palletizing head assembly of a throwing-type automatic stacking machine, including a bracket set on the frame of the throwing-type automatic stacking machine, wherein the bracket is provided with a vertically oriented rotating frame and a rotating mechanism capable of driving the rotating frame to rotate horizontally, wherein the rotating frame is provided with a horizontally oriented rotating frame and a rotating mechanism capable of driving the rotating frame to rotate, wherein the rotating frame is provided with a material trough, and wherein the rotating frame is provided with an inclined feeding mechanism, wherein the feeding mechanism includes an inlet end and an outlet end, and the outlet end is located above the material trough.
[0006] During operation, bagged or boxed materials are conveyed to the feed end of the feeding mechanism and slide into the material trough through the discharge end. When the angle of the material trough needs to be adjusted, the rotating mechanism one drives the rotating frame one to rotate horizontally to the required angle. Then, the rotating mechanism two drives the rotating frame two to rotate, causing the material in the material trough to be thrown to the outside of the material trough, thus completing the stacking. The rotating mechanism one drives the rotating frame one to rotate to different angles for multi-angle stacking, which can accurately stack materials in narrow spaces, such as carriages. It is also suitable for accurately stacking pallets, and has the advantages of accurate stacking, high stacking efficiency, and wide applicability.
[0007] In the palletizing head assembly of the aforementioned throwing-type automatic stacking machine, the rotating mechanism includes a slewing bearing disposed between a support and a rotating frame. The slewing bearing includes an inner ring, an outer ring, ball bearings, and an external gear ring. The outer ring is fixedly connected to the support, and the inner ring is fixedly connected to the rotating frame. A motor is mounted on the support, and the shaft of the motor is fixedly connected to a gear that meshes with the external gear ring. The motor drives the rotating frame to rotate via the slewing bearing, facilitating control of the rotation angle of the rotating frame and offering advantages such as reliable structure and stable operation.
[0008] In the palletizing head assembly of the aforementioned throwing-type automatic stacking machine, the rotating mechanism includes a turntable axially fixed to a support. The turntable is fixedly connected to the rotating frame, and a worm gear is fixedly connected to the turntable. A motor is mounted on the support, and the shaft of the motor is fixedly connected to a worm that meshes with the worm gear. The motor drives the turntable to rotate through the transmission of the worm gear, thereby driving the rotating frame to rotate. This design offers advantages such as structural stability and reliable operation.
[0009] In the palletizing head assembly of the aforementioned throwing-type automatic stacking machine, the second rotating mechanism is a second motor whose housing is fixedly connected to the first rotating frame, and the rotating shaft of the second motor is fixedly connected to the second rotating frame.
[0010] In the palletizing head assembly of the aforementioned throwing-type automatic stacking machine, the feeding mechanism includes a row of rollers axially fixed to the rotating frame. Adjacent rollers are driven by synchronous belts and pulley assemblies. The rotating frame is equipped with a motor that can drive the rollers to rotate. The motor drives the rollers to rotate, allowing the material on the rollers to be smoothly conveyed into the feeding trough, while also accelerating the material conveying and improving conveying efficiency. Alternatively, the aforementioned row of rollers can be replaced by a conveyor belt.
[0011] In the palletizer head assembly of the aforementioned throwing-type automatic bagging machine, a feeding groove is provided around the middle of the roller at the feeding end of the feeding mechanism. By providing the feeding groove, the bagged material can be kept in a centered position on the roller, ensuring smooth feeding.
[0012] In the palletizing head assembly of the aforementioned throwing-type automatic stacking machine, a sensing device is provided on the rotating frame and is located above the roller. By setting the aforementioned sensing device to sense the bagged material passing through the feeding mechanism, the sensed signal is sent to the controller of the automatic stacking machine, enabling the operation to proceed smoothly.
[0013] In the palletizing head assembly of the aforementioned throwing-type automatic bagging machine, the sensing device includes a swing arm fixedly connected to the rotating frame. The upper end of the swing arm horizontally passes through the rotating frame, and the lower end of the swing arm is located above the roller. A turntable is vertically fixedly connected to the upper end of the swing arm. A metal sensor is fixedly connected to the rotating frame, and the metal sensor can sense the rotation of the turntable. When the bagged material passes through the roller, the bagged material pushes the swing arm to rotate, which in turn drives the turntable to rotate. Then, the induction switch senses the rotation of the turntable and sends the sensed signal to the controller of the automatic bagging machine. This mechanical sensing device is reliable in operation, sensitive in sensing, and has a long service life.
[0014] In the palletizing head assembly of the aforementioned throwing-type automatic stacking machine, the turntable has a notch, and the metal sensor is located at the notch of the turntable.
[0015] In the palletizing head assembly of the aforementioned throwing-type automatic stacking machine, the sensing device is an infrared sensor fixedly connected to the rotating frame.
[0016] In the palletizing head assembly of the aforementioned throwing-type automatic stacking machine, a rotating shaft is fixedly connected to the middle of the rotating frame two, and the main shaft of the motor two is fixedly connected to the rotating shaft. The material placement trough includes a base plate fixedly connected to the rotating frame one, the base plate being arranged parallel to one side of the rotating shaft, and the base plate having two side baffles and a front baffle, all of which are inclined outwards. With this configuration, when the rotating frame two drives the material placement trough to rotate and throw bagged materials, the side baffles and front baffle will not interfere with the packaging bags, avoiding friction and improving the accuracy and reliability of the throwing process.
[0017] In the palletizing head assembly of the aforementioned throwing-type automatic stacking machine, the rotating frame two is provided with material placement grooves on both its upper and lower sides, and these grooves are symmetrically arranged on both sides of the rotating shaft. The symmetrical placement of material placement grooves on both the upper and lower sides of the rotating frame two improves work efficiency.
[0018] Compared with existing technologies, the palletizer head assembly of this throwing-type automatic stacking machine has the following advantages:
[0019] 1. The rotating mechanism drives the rotating frame to rotate horizontally to the required angle, and then the rotating mechanism drives the rotating frame to rotate, so that the material in the material trough is thrown to the outside of the material trough, thus completing the stacking. The rotating mechanism drives the rotating frame to rotate to different angles to perform multi-angle stacking, which can accurately stack in narrow spaces and is also suitable for accurately stacking pallets. It has the advantages of accurate stacking, high stacking efficiency and wide applicability.
[0020] 2. The motor drives the rotating frame to rotate through the slewing bearing, which makes it easy to control the rotation angle of the rotating frame and has the advantages of reliable structure and stable operation.
[0021] 3. The rollers are driven by the motor to rotate, so that the material on the rollers can be smoothly transported into the material trough. At the same time, the material can be transported faster, which improves the conveying efficiency.
[0022] When bagged material passes through the rollers, the bagged material pushes the swing arm to rotate, the swing arm drives the turntable to rotate, and then the induction switch senses the rotation of the turntable and sends the sensed signal to the controller of the automatic bagging machine. Through the above-mentioned mechanical sensing device, it is reliable in operation, sensitive in sensing, and has a long service life.
[0023] The roller has a feeding groove in the middle, which allows the bagged material to be kept in the center of the roller and fed smoothly. Attached Figure Description

[0031] The rotating mechanism 3 includes a slewing bearing 3a disposed between the support 1 and the rotating frame 2. The slewing bearing 3a includes an inner ring, an outer ring, balls, and an outer gear ring. The outer ring is fixedly connected to the support 1, and the inner ring is fixedly connected to the rotating frame 2. The support 1 is equipped with a motor 3b. The rotating shaft 4a of the motor 3b is fixedly connected to a gear that meshes with the outer gear ring. The motor 3b drives the rotating frame 2 to rotate through the slewing bearing 3a, which facilitates control of the rotation angle of the rotating frame 2 and has the advantages of reliable structure and stable operation.
[0032] As another approach, the rotating mechanism 3 includes a turntable 8b axially fixed to the support 1. The turntable 8b is fixed to the rotating frame 2. A worm gear is fixed to the turntable 8b. A motor 3b is mounted on the support 1. The rotating shaft 4a of the motor 3b is fixed to a worm gear that meshes with the worm gear. The motor 3b drives the turntable 8b to rotate through the transmission of the worm gear and worm gear, thereby driving the rotating frame 2 to rotate. This mechanism has the advantages of stable structure and reliable operation.
[0033] The rotating mechanism 2 5 is a motor 2 5a whose housing is fixedly connected to the rotating frame 1 2, and the rotating shaft 4a of the motor 2 5a is fixedly connected to the rotating frame 2 4.
[0034] The feeding mechanism 7 includes a row of rollers 7a axially fixed to the rotating frame 2. Adjacent rollers 7a are driven by a synchronous belt and a pulley assembly. The rotating frame is equipped with a motor 7c that can drive the rollers 7a to rotate. A feeding groove 7b is provided around the middle of the rollers 7a at the feeding end, so that the bagged material entering the rollers 7a at the feeding end can be kept in a central position on the rollers 7a and can be fed smoothly.
[0035] A sensing device 8 is provided on the rotating frame 2 and is located above the roller 7a. The sensing device 8 includes a swing arm 8a fixed to the rotating frame 2. The upper end of the swing arm 8a passes horizontally through the rotating frame 2, and the lower end of the swing arm 8a is located above the roller 7a.

The material troughs 6 are symmetrically arranged on both sides of the rotating shaft 4a, which improves working efficiency.
[0037] During operation, bagged or boxed materials are conveyed to the feeding end of the feeding mechanism 7. The motor 7c drives the roller 7a to rotate, accelerating the conveying of the material on the roller 7a. The material then slides into the material trough 6 through the discharge end. When the bagged material passes through the roller 7a at the discharge end, the bagged material pushes the swing arm 8a to rotate. The swing arm 8a drives the turntable 8b to rotate. Then, the induction switch senses the rotation of the turntable 8b and sends the sensed signal to the controller of the automatic packing machine. When the angle of the material trough 6 needs to be adjusted, the controller controls motor 3b to drive the slewing bearing 3a, and drives the rotating frame 2 to rotate to the required angle. Then, motor 5a drives the rotating frame 4 to rotate, so that the material in the material trough 6 is thrown to the outside of the material trough 6, completing the stacking. By using motor 3b and slewing bearing 3a to drive the rotating frame 2 to rotate to different angles for multi-angle stacking, it can accurately stack in narrow spaces, such as carriages, and is also suitable for accurately stacking pallets. It has the advantages of accurate stacking, high stacking efficiency and wide applicability.
