Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, and in particular to a device for batch - conveying continuously - conveyed materials to be packaged according to the quantity of packing and sub - packing. Background Art

[0002] In the mass production of certain products, especially daily - used products, for the convenience of transportation and storage, it is necessary to carry out enlarged packaging according to the set quantity and shape. For example, small packs of tissue paper that are convenient for people to use are packaged into large packs of tissue paper in quantities of 12 small packs. Before these products enter the enlarged - packaging process, it is necessary to batch - convey the continuously output small products or small - pack products through a material - distributing conveyor device according to the set quantity and packaging requirements. In particular, according to the layout of the production line, a turning material - distributing conveyor device is often used to change the conveying direction for batch - conveying.

[0003] An existing turning material - distributing conveyor device has a feeding channel for continuous feeding, the conveying direction of which is perpendicular to the conveying direction of the discharging channel for batch - conveying. Both the feeding channel and the discharging channel use conveyor belts to convey materials. A turning pushing platform is arranged between the feeding conveyor belt and the discharging conveyor belt, and a pushing mechanism is installed beside the turning pushing platform. The pushing mechanism includes a push rod that moves linearly and reciprocally in the conveying direction of the discharging conveyor belt. One end of the push rod is fixed with a pushing plate perpendicular to the turning pushing platform, and the surface of the pushing plate faces the conveying direction of the discharging conveyor belt. The other end of the push rod is hinged to the extending end of a cylinder through a connecting rod, and the piston rod of the cylinder moves in the opposite direction to the movement direction of the push rod. The above - mentioned device realizes quantitative material distribution through intermittent feeding and reciprocating pushing. The materials to be packaged are stacked along the conveying direction on the feeding conveyor belt. The feeding conveyor belt is driven to run towards the turning pushing platform. When a predetermined quantity of materials to be packaged is conveyed to the turning pushing platform through the feeding conveyor belt, in order to avoid the interference of the materials to be packaged immediately following with the pushing, the feeding conveyor belt reversely retreats a short distance to avoid the pushing plate. Subsequently, the feeding conveyor belt remains stationary waiting for the next feeding. At the same time, the cylinder of the pushing mechanism pushes the push rod, and the push rod drives the pushing plate to push the predetermined quantity of materials to be packaged on the turning pushing platform onto the discharging conveyor belt, completing the material - distribution operation. The materials to be packaged after material distribution are conveyed by the discharging conveyor belt to the next process. The device with this structure has the following deficiencies: it cannot feed continuously, and it is necessary to wait for the pushing mechanism to push and reset before the next feeding, so the feeding speed is slow; it is difficult to increase the pushing speed of the pushing mechanism. Because increasing the pushing speed will cause the unstable operation of the mechanism, and after the mechanism with linear reciprocating motion is speeded up, it will cause damage to easily - damaged materials such as rolled paper due to too large momentum, affecting product quality. Summary of the Invention

[0004] The purpose of the present invention is to provide a turning material - distributing conveyor device that can feed and distribute materials continuously, quickly, and reliably.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: This steering and material distributing conveyor device includes a feeding channel and a discharging channel with different conveying directions. The feeding channel is provided with a low-speed conveyor belt and a high-speed conveyor belt at the end of the channel. There is a gap section between the low-speed conveyor belt and the high-speed conveyor belt. A position sensor is installed in the section of the high-speed conveyor belt.

[0006] A material distributing table is provided between the outlet end of the feeding channel and the inlet end of the discharging channel.

[0007] There is a material pushing mechanism, which includes a material pushing servo motor installed on a material pushing servo frame, a main rotating arm installed on a rotating shaft driven by the material pushing servo motor, a secondary rotating arm hinged to the main rotating arm, and a material pusher hinged to the secondary rotating arm. A mechanical transmission device for synchronous rotation is connected between the central axis of the main rotating arm and the hinge axis of the secondary rotating arm. A mechanical transmission device for synchronous rotation is connected between the hinge axis of the secondary rotating arm and the hinge axis of the material pusher.

[0008] The movement trajectory of the material pusher crosses over the top surfaces of the material distributing table and the bottom plate of the discharging channel.

[0009] The discharging channel includes a bottom plate of the discharging channel, and a discharging material pushing rod whose movement trajectory crosses over the bottom plate of the discharging channel and is connected to a discharging driving chain.

[0010] The low-speed conveyor belt servo motor for driving the low-speed conveyor belt, the high-speed conveyor belt servo motor for driving the high-speed conveyor belt, the chain servo motor for driving the discharging driving chain, and the material pushing servo motor are all connected to an electric controller through motor drivers. The input end of the electric controller is connected to the position sensor.

[0011] In the technical solution of the above steering and material distributing conveyor device, a more specific technical solution may further be: Both the low-speed conveyor belt and the high-speed conveyor belt are a pair of clamping conveyor belts arranged on both sides of the bottom plate of the feeding channel with the driving axis vertically erected. Material distributing driving chains are installed on both sides of the material distributing table, and a material distributing material pushing rod whose movement trajectory crosses over the material distributing table is connected above the material distributing driving chains.

[0012] Further, there are multiple pieces of the material distributing material pushing rods, which are arranged at equal distances on the material distributing driving chains; there are multiple groups of the material pusher and the secondary rotating arm connected thereto, and they are evenly distributed around the central axis of the main rotating arm on the main rotating arm.

[0013] Further, both the low-speed conveyor belt and the high-speed conveyor belt are conveyor belts arranged at the bottom of the feeding channel with the driving axis horizontally set.

[0014] Furthermore, the discharging and pushing rods are multiple, and they are arranged at equal distances on the discharging drive chain; the pushing members and the secondary rotating arms connected thereto are multiple groups, and they are evenly distributed on the main rotating arm with the central axis of the main rotating arm as the center.

[0015] Furthermore, a protruding hook is provided at one end of the pushing member close to the feeding channel.

[0016] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0017] 1. The present application sets a low-speed conveyor belt for continuous feeding and a high-speed conveyor belt for separating materials by pulling apart the material spacing in the feeding channel. A position sensor is installed in the interval of the high-speed conveyor belt, which can detect the transmission error caused by the operation error of the mechanism and other factors, and the low-speed conveyor belt for continuous feeding makes corresponding position compensation, thereby improving the accuracy and reliability of the separation position; a spacing section is set between the low-speed conveyor belt and the high-speed conveyor belt, which can prevent the excessively long materials from being clamped by the low-speed and high-speed conveyor belts at the same time, thereby preventing the materials from being pulled; the setting, structure and mutual relationship of the separation table and the pushing mechanism between the outlet end of the feeding channel and the inlet end of the discharging channel can enable the pushing mechanism to push the materials on the separation table to the discharging channel in a cyclic and continuous manner by rotating; the discharging material pusher on the discharging channel receives the materials pushed by the pushing mechanism and stably delivers the materials to the next packaging station; the present invention can continuously divide the materials continuously arranged on the conveyor belt into a certain number of groups, and at the same time, when the materials pass through a corner, the equipment does not need to stop and wait intermittently, thereby realizing the continuous operation of the equipment, thereby greatly improving the feeding and separation speeds.

[0018] 2. The low-speed and high-speed conveyor belts are clamping conveyor belts that can be installed horizontally or vertically, so that materials can be continuously fed in a tightly arranged manner; the material distribution table is provided with a distribution rod whose movement trajectory crosses the distribution table, which can transfer the materials in batches to the pushing range of the pushing mechanism, and cooperates precisely with the pushing mechanism to prevent the materials from tilting and detaching from the pushing parts, causing the pushing failure.

[0019] 3. The discharging rods on the discharging channel are set at equal distances to ensure that the materials on the discharging channel maintain the same spacing, so that the materials can be accurately delivered to the subsequent packaging station.

[0020] 4. A hook is arranged at one end of the pusher close to the feeding channel, which can replace the material dividing lever on the dividing table to divide the material, so that the material can be pushed to the discharging channel along with the pusher. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further described in detail below in conjunction with the embodiments with reference to the drawings:

[0027] Embodiment 1

[0028] Figure 1 , Figure 2 In the illustrated embodiment, the feeding channel of the present turning and distributing conveyor device is composed of a feeding channel bottom plate 2 installed on the feeding channel frame 1, a low-speed conveyor belt 3 composed of a pair of clamping conveyor belts with the driving axis vertically arranged and installed on both sides of the feeding channel bottom plate 2, a high-speed conveyor belt 5 composed of a pair of clamping conveyor belts with the driving axis vertically arranged and installed on both sides of the feeding channel bottom plate 2, and guard plates 4 arranged on both sides of the feeding channel bottom plate 2 in the interval section between the low-speed conveyor belt 3 and the high-speed conveyor belt 5. The guard plate 4 includes a mounting seat and a thin sheet elastically connected to the inner side of the mounting seat.

[0029] A distributing table surface 7 formed by the top surface of a distributing plate installed on the feeding channel frame 1 is provided between the outlet end of the feeding channel and the inlet end of the discharging channel; distributing driving chains 8 are installed on both sides of the distributing table surface 7, and a material distributing and deflecting rod 9 that moves around the distributing table surface 7 and whose movement track crosses five material distributing and deflecting rods 9 on the distributing table surface 7 is connected above the distributing driving chains 8, and the material distributing and deflecting rods 9 are equidistantly arranged on the distributing driving chains 8.

[0030] The material conveying directions of the feeding channel and the discharging channel are set at a 90-degree angle. There is a pusher mechanism which has a pusher servo frame 11 installed on the discharging channel frame 15. A pusher servo motor 10 is installed on the pusher servo frame 11. A main rotating arm 17 in the shape of a long plate is fixedly connected to the rotating shaft of the pusher servo motor 10. At both ends of the main rotating arm 17, a set of pusher components composed of a secondary rotating arm 23 and a pusher connecting piece 25 and a pusher rod 26 hinged on the secondary rotating arm 23 are hinged. A hook 27 extends from one end of the pusher rod 26. A first synchronous belt gear 16 fixedly connected to the central axis of the main rotating arm 17, a second synchronous belt gear 19 fixedly connected to the hinge axis of the secondary rotating arm 23, the main synchronous belt 18 and the tension pulley 28 form a mechanical transmission device for synchronous rotation, enabling the rotation of the main rotating arm 17 and the rotation of the secondary rotating arm 23 to achieve synchronous transmission; a third synchronous belt gear 20 fixedly connected to the hinge axis of the secondary rotating arm 23, a fourth synchronous belt gear 22 fixedly connected to the hinge axis of the pusher connecting piece 25 and the secondary synchronous belt 21 form a mechanical transmission device for synchronous rotation, enabling the rotation of the secondary rotating arm 23 and the rotation of the pusher connecting piece 25 to achieve synchronous transmission; the pusher surface of the pusher rod 26 remains parallel to the continuous feeding channel and always faces the discharging direction of the discharging channel. In the pusher mechanism of this steering and distributing conveyor device, there are two groups of secondary rotating arms 23 connected to the pusher rod 26 and the pusher connecting piece 25, and they are evenly distributed around the central axis of the main rotating arm on the main rotating arm 17. (In other embodiments, the rotating shaft of the pusher servo motor 10 and the pusher components can achieve synchronous transmission through a planetary gear train.) The pusher components are higher than the distributing and feeding rod 9 and the discharging and feeding rod 14 to avoid movement interference of the mechanism components.

[0031] The discharging channel of this steering and distributing conveyor device consists of a discharging channel bottom plate 12 installed on the discharging channel frame 15, discharging drive chains 13 installed on both sides of the discharging channel bottom plate 12, and eight discharging and feeding rods 14 whose movement trajectories are equidistantly arranged on the discharging drive chains 13 and cross over the discharging channel bottom plate 12, etc.

[0032] The low-speed conveyor belt servo motor for driving the low-speed conveyor belt 3, the high-speed conveyor belt servo motor for driving the high-speed conveyor belt 5, the chain servo motor for driving the discharging drive chains 13 and the pusher servo motor 10 of this steering and distributing conveyor device are all connected to the electric controller through motor drivers, and the input end of this electric controller is connected to a position sensor 6.

[0033] As Figure 3As shown, when the steering material distribution and conveying device is working, the materials to be distributed are in a full state and tightly arranged in the channel of the low-speed conveyor belt 3. The low-speed conveyor belt 3 moves in a uniform cycle under the drive of the low-speed conveyor belt servo motor, and continuously clamps and transmits the materials to be distributed along the feeding direction of the feeding channel to the channel of the high-speed conveyor belt 5. At the same time, the high-speed conveyor belt 5 moves in a uniform cycle under the drive of the high-speed conveyor belt servo motor. In this embodiment, the speed of the high-speed conveyor belt 5 is twice that of the low-speed conveyor belt 3; when the first material reaches the preset initial distribution position of the high-speed conveyor belt 5, the material unit formed by several materials clamped between the high-speed conveyor belt 5 is separated from the next material and sent to the distribution table 7, and then the next round of distribution begins; the above-mentioned preset initial distribution position is the projection position of the detection light emitted by the position sensor 6 on the bottom plate 2 of the feeding channel. When the material dividing and dispensing rod 9 on the material dividing table 7 contacts the material unit, the material unit is pushed into the pushing range of the pushing mechanism; when the pushing rod 26 of the pushing mechanism receives the material unit, it cooperates with the material dividing and dispensing rod 9 to completely push the material unit to the discharging channel, and when the discharging and dispensing rod 14 on the discharging channel contacts the material unit, the material unit is pushed to move in the discharging direction on the bottom plate 12 of the discharging channel; at the same time, another pushing member of the pushing mechanism running at a uniform speed rotates to the receiving position of the next material unit to repeat the same pushing action. In the above process, when the position sensor 6 detects that the actual running material length in the current operation cycle is different from the value of the set running material length in the set operation cycle of the low-speed conveyor belt 3, the position sensor 6 feeds back a signal to the electric controller, and the electric controller issues a command to adjust the running material length of the next operation cycle, and the low-speed conveyor belt 3 performs position compensation for the actual initial material dividing position of the current first material according to the preset initial material dividing position.

[0034] Example 2

[0035] Figure 4In the embodiment shown, the feeding channel is mainly composed of a low-speed conveyor belt 30 for holding materials, which is composed of two sets of upper and lower conveyor belts with horizontally arranged drive shafts respectively mounted on two brackets 29, and a high-speed conveyor belt 32 for holding materials, which is composed of two sets of upper and lower conveyor belts with horizontally arranged drive shafts, and a position sensor 33 arranged between the high-speed conveyor belt 32, and there is also a spacing section 31 between the high-speed conveyor belt 32 and the low-speed conveyor belt 30. An equidistant material distribution mechanism with material distribution and material distribution rods 35 is provided at the outlet end of the high-speed conveyor belt 32, and the equidistant material distribution mechanism includes a material distribution table 36 formed on the top surface of the material distribution plate mounted on the material distribution frame 34, and material distribution drive chains 37 are installed on both sides of the material distribution table 36, and the material distribution drive chain 37 is connected to a plurality of material distribution and material distribution rods 35 that move around the material distribution table 36, and its movement trajectory passes over the material distribution table 36. The material distribution and material distribution rods 35 are arranged at equal distances on the material distribution drive chain 37. The material dividing and shifting rod 35 can prevent the hook 38 at the end of the push rod 39 from being unable to push the material as a whole when the length of the material in the horizontal plane perpendicular to the push rod 39 is too long, causing the material to fall around the end of the hook 38. This embodiment eliminates the discharge drive chain and the discharge and shifting rod on both sides of the discharge channel bottom plate in embodiment 1, and the discharge channel bottom plate is formed into a pusher bottom plate 40 below the pusher mechanism at the corner of the equidistant dividing mechanism and the discharge channel. The remaining features are the same as those in embodiment 1.

[0036] During operation, the low-speed conveyor belt 30 will uniformly deliver the closely arranged materials to be distributed in a full state into the high-speed conveyor belt 32. The high-speed conveyor belt 32 will pull a distance between the material unit formed by several materials in it and the next material behind it and then deliver it to the distribution table 36. When the distribution and selection rod 35 crossing the distribution table 36 contacts the material unit, the material unit is pushed into the pushing range of the pushing mechanism; the hook 38 at the end of the pushing rod 39 is inserted into the empty space between the material unit and the subsequent material. After the pushing surface and hook 38 of the pushing rod 39 contact the material unit, they push the material unit to move on the pushing bottom plate 40 until the material unit is pushed to the next packaging station of the discharge channel.

[0037] Example 3

[0038] Figure 5 In the embodiment shown, the equidistant material distribution mechanism in embodiment 2 is cancelled, the feed end of the push plate is arranged at the outlet end of the high-speed conveyor, and the other features are the same as those in embodiment 2. The steering material distribution conveyor device of this embodiment can convey materials with a shorter length perpendicular to the direction of the push rod in the horizontal plane, and the material unit is pushed by the push surface and hook of the push rod to move on the material distribution table and the push bottom plate after contacting the material unit, and the material dumping phenomenon will not occur.
