Description

Technical Field

[0001] The invention relates to the technical field of packaging, and in particular to a material arranging mechanism of a packaging machine. Background Art

[0002] During the production process of the assembly line, after the product is manufactured, a packaging machine is usually used to automatically package the product to ensure that the product will not be contaminated or damaged for the second time.

[0003] The arrangement mechanism of the packaging machine is used to arrange the products according to the set positional relationship. The distribution of the products after arrangement corresponds to the design of the packaging, ensuring that the products can accurately enter the corresponding space of the packaging. For example, the Chinese utility model patent with the authorization announcement number CN210311073U and the authorization announcement date of 2020.04.14 discloses an automatic sorting and packing machine for finished beverages, and specifically discloses that the packing machine includes a transverse conveying module and a longitudinal pushing module; the interior of the transverse conveying module is divided into multiple intervals by a partition, and a diverter plate that can be translated left and right is set at the left end of the transverse conveying module. The diverter plate moves in the direction of beverage delivery to prevent it from being skewed or overturned due to extrusion when entering the partition, and prevents the tilted beverage from blocking the partition feeding area, so as to achieve accurate and fast quantitative packaging.

[0004] During operation, the transverse conveyor belt conveys the separated beverages to the longitudinal conveying and pushing module, and the pushing cylinder pushes the pushing plate to move forward and backward to push the beverages to the working slope, thereby realizing the sorting and overall quantitative pushing of the beverages. Although, the automatic sorting and packing machine for finished beverages in the prior art can push multiple rows of finished beverages to the packaging position as a whole.

[0005] However, in actual packaging production, a package is usually designed with multiple independent spaces for accommodating a single product. Obviously, the existing automatic sorting and packing machines cannot ensure that a single product is accurately placed in the independent space of the package, and there is a problem of low material arrangement accuracy. Summary of the invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a material arrangement mechanism for a packaging machine to solve the problem that the existing automatic sorting and packing machines cannot ensure that a single product accurately enters the independent space of the package and have low material arrangement accuracy.

[0007] The technical solution of the material arrangement mechanism of the packaging machine of the present invention is:

[0008] The material arrangement mechanism of the packaging machine includes a feeding module, a discharging module and a discharging module, wherein the feeding module is connected to the discharging module, and the discharging module includes a discharging driving structure and a discharging member drivingly connected to the discharging driving structure;

[0009] The edge of the material discharging member is provided with a plurality of material taking grooves, the plurality of material taking grooves are arranged at intervals parallel to the driving direction of the material discharging driving structure, and the material taking grooves are used to match the outer contour of a single product;

[0010] The unloading module includes a supporting plate and a material blocking structure. The supporting plate is arranged at one end of the driving direction of the discharge driving structure, and a plurality of material guide holes corresponding to the material trough are provided on the supporting plate. The material blocking structure is movably mounted on the supporting plate.

[0011] Furthermore, the discharge piece is a fishbone-shaped structure, which includes a strip-shaped main body part and raised parts connected to both sides of the strip-shaped main body part. There are multiple raised parts arranged at intervals along the length direction of the strip-shaped main body part, and the interval between two adjacent raised parts constitutes the material trough.

[0012] Furthermore, the protruding portion extends obliquely along a length direction inclined to the strip-shaped main body portion, and an acute angle is formed between the extending direction of the protruding portion and the pushing direction of the discharge driving structure.

[0013] Furthermore, the discharge module also includes a discharge guide groove, and the discharge member is movably installed in the discharge guide groove.

[0014] Furthermore, the discharge drive structure is a discharge drive cylinder, and the discharge member has a discharge position corresponding to the support plate, and a material taking position for withdrawing to the discharge guide groove;

[0015] The discharging drive cylinder is electrically connected to a first stroke sensor and a second stroke sensor, the first stroke sensor is used to send a stop signal to the discharging drive cylinder when the discharging piece is in the discharging position, and the second stroke sensor is used to send a stop signal to the discharging drive cylinder when the discharging piece is in the picking position.

[0016] Furthermore, the feeding module includes a vibration plate, a feeding guide groove and a blowing structure, and the feeding guide groove is connected between the vibration plate and the discharge guide groove.

[0017] Furthermore, the blowing structure is provided with an air blowing pipe, the air blowing pipe is connected to the feeding guide groove, and the pipe opening of the air blowing pipe is arranged toward the discharging guide groove.

[0018] Furthermore, a full material detection element is also provided on the feeding guide chute, and the full material detection element is electrically connected to the vibration plate. The full material detection element is used to send a stop signal to the vibration plate when the feeding guide chute is full of products.

[0019] Furthermore, the feeding modules are provided with two groups, and the two groups of the feeding modules are symmetrically arranged on both sides of the discharging module.

[0020] Furthermore, the material blocking structure is a material blocking plate movably mounted on the upper side of the material supporting plate, and the outer side of the material blocking plate is also connected to a material blocking driving structure.

[0021] Beneficial effect: When the material arrangement mechanism is working, the feeding module is used to transport the supplied products to the discharging module. Since the edge of the discharging piece of the discharging module is provided with a material taking groove, and the material taking groove can only accommodate and cooperate with a single product; in the process of the discharging drive structure driving the discharging piece to advance toward the unloading module, the products enter the material taking groove of the discharging piece in turn, and the products that have entered the material taking groove are pushed forward together with the discharging piece, and then the discharging piece is loaded with products and enters the subsequent unloading module.

[0022] Since the distribution position of the material taking trough on the discharge piece is fixed, the relative position of the product on the discharge piece remains unchanged. When the discharge piece after obtaining the product is pushed onto the support plate, the product can accurately correspond to the guide hole on the support plate; when the blocking structure moves away from the blocking position, the product can accurately fall into the corresponding packaging, so that a single product can accurately enter the independent space of the packaging, and the material arrangement accuracy is higher.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] A specific embodiment 1 of the material arrangement mechanism of the packaging machine of the present invention is as follows: Figures 1 to 3 As shown, the material arrangement mechanism of the packaging machine includes a feeding module 1, a discharging module 2 and a unloading module 3. The feeding module 1 is connected to the discharging module 2. The discharging module 2 includes a discharging drive structure and a discharging member 22 which is transmission-connected to the discharging drive structure. A plurality of material taking grooves 220 are arranged at an edge of the discharging member 22. The plurality of material taking grooves 220 are arranged at intervals parallel to the driving direction of the discharging drive structure. The material taking grooves 220 are used to cooperate with the outer contour of a single product 4. The unloading module 3 includes a supporting plate 31 and a material blocking structure. The supporting plate 31 is arranged at one end of the driving direction of the discharging drive structure, and a plurality of material guide holes 310 corresponding to the material taking grooves 220 are provided on the supporting plate 31. The material blocking structure is movably mounted on the supporting plate 31.

[0029] When the material arrangement mechanism is working, the feeding module 1 is used to transport the supply product 4 to the discharging module 2. Since the edge of the discharging piece 22 of the discharging module 2 is provided with a material taking groove 220, and the material taking groove 220 can only accommodate and cooperate with a single product 4; in the process of the discharging driving structure driving the discharging piece 22 to advance toward the unloading module 3, the products 4 enter the material taking groove 220 of the discharging piece 22 in turn, and the product 4 that has entered the material taking groove 220 is pushed together with the discharging piece 22, and then the discharging piece 22 is loaded with the product 4 and enters the subsequent unloading module 3.

[0030] Since the distribution position of the material taking trough 220 on the discharge piece 22 is fixed, the relative position of the product 4 on the discharge piece 22 remains unchanged. When the discharge piece 22 after obtaining the product 4 is pushed onto the supporting plate 31, the product 4 can accurately correspond to the material guide hole 310 on the supporting plate 31; when the blocking structure moves away from the blocking position, the product 4 can accurately fall into the corresponding packaging 5, so that a single product 4 can accurately enter the independent space of the packaging 5, and the material arrangement accuracy is higher.

[0031] In this embodiment, the discharge member 22 is a fishbone structure, which includes a strip-shaped main body and a protruding portion 23 connected to the outside of the strip-shaped main body. A plurality of protruding portions 23 are arranged at intervals along the length direction of the strip-shaped main body, and the interval between two adjacent protruding portions 23 constitutes a material collection trough 220. Specifically, the protruding portion 23 extends obliquely along the length direction inclined to the strip-shaped main body, and an acute angle is formed between the extending direction of the protruding portion 23 and the pushing direction of the discharge drive structure. Furthermore, the shape of the material collection trough 220 is U-shaped, and the notch thereof forms an angle of 45° with the pushing direction of the discharge drive structure; during the pushing movement, the product 4 is stopped by the protruding portion 23 in the material collection trough 220, ensuring that it does not slip off the discharge member 22, and ensuring that the product 4 can be stably pushed into the unloading module 3.

[0032] The discharge module 2 further includes a discharge guide groove 24, in which a discharge member 22 is movably installed. Moreover, the discharge drive structure is a discharge drive cylinder 21, and the discharge member 22 has a discharge position corresponding to the support plate 31, and a material taking position for exiting the support plate 31; the discharge drive cylinder 21 is electrically connected with a first stroke sensor 211 and a second stroke sensor 212, and the first stroke sensor 211 is used to send a stop signal to the discharge drive cylinder 21 when the discharge member 22 is in the discharge position, and the second stroke sensor 212 is used to send a stop signal to the discharge drive cylinder 21 when the discharge member 22 is in the material taking position.

[0033] Specifically, the discharge drive cylinder 21 uses a magnetic ring cylinder, and the type of the discharge drive cylinder 21 is determined according to the material arrangement distance, or according to the movement required by the discharge piece 22. The first stroke sensor 211 is used to detect whether the discharge drive cylinder 21 pushes the discharge piece 22 to the discharge position, and sends a stop signal to the discharge drive cylinder 21 when it reaches the discharge position; correspondingly, the second stroke sensor 212 is used to detect whether the discharge drive cylinder 21 drives the discharge piece 22 to the material collection position, and sends a stop signal to the discharge drive cylinder 21 when it reaches the material collection position, ensuring that the discharge drive cylinder 21 drives the discharge piece 22 forward and backward to the position.

[0034] In this embodiment, the feeding module 1 includes a vibration plate 11, a feeding guide groove 12 and a blowing structure, and the feeding guide groove 12 is connected between the vibration plate 11 and the discharge guide groove 24. The vibration plate 11 is an existing centrifugal vibration plate, and centrifugal vibration is used to arrange the products 4 in a uniform direction and feed them into the feeding guide groove 12. It should be noted that the bottom of the vibration plate 11 is padded with shockproof rubber and the shockproof rubber is fixed to prevent the vibration plate 11 from shifting, and a gap of 1.5mm to 2.5mm is provided between the vibration plate 11 and the feeding guide groove 12 to prevent the vibration plate 11 from hitting the feeding guide groove 12.

[0035] The blowing structure is provided with a blowing pipe 13, which is connected to the feeding guide groove 12, and the pipe opening of the blowing pipe 13 is arranged toward the discharge guide groove 24. The blowing structure is an air compressor, which uses the air compressor and the blowing pipe 13 to form a high-pressure airflow for the product 4 in the feeding guide groove 12. When conveying the feed, the solenoid valve of the air compressor is opened 0.2s in advance, and the compressed gas is blown from the pipe opening of the blowing pipe 13 to the discharge guide groove 24, and the product 4 is blown along the feeding guide groove 12 to the material taking groove 220 of the discharge member 22.

[0036] A full material detection element 14 is also provided on the feeding guide 12. The full material detection element 14 is electrically connected to the vibration disk 1. The full material detection element 14 is used to send a stop signal to the vibration disk 11 when the feeding guide 12 is full of products. Specifically, the full material detection element 14 is an optical fiber sensor. When the sensing time of the optical fiber sensor exceeds 1s, it means that the feeding guide 12 is full of products 4. At this time, the full material detection element 14 sends a stop signal to the vibration disk 11, and the vibration disk 11 stops vibrating, avoiding the vibration disk 11 from working continuously, effectively saving electric energy. Moreover, the feeding module 1 is provided with two groups, and the two groups of feeding modules 1 are symmetrically arranged on both sides of the discharge module 2, so as to respectively convey the supply products 4 to the material troughs 220 on both sides of the discharge member 22, which significantly improves the working efficiency of the arrangement mechanism.

[0037] In addition, the material blocking structure is a material blocking plate 32 that is movably mounted on the upper side of the support plate 31, and a material blocking driving structure 33 is also connected to the outer side of the material blocking plate 32. Before the discharge member 22 is pushed into place, the material blocking plate 32 is located on the upper side of the support plate 31 to hold the product 4 and prevent it from falling from the material guide hole 310; when the discharge member 22 is pushed into the discharge position, the material blocking driving structure 33 drives the material blocking plate 32 to be pulled outward, so that the product 4 enters the packaging 5 below through the material guide hole 310.

[0038] In other specific embodiments of the material arrangement mechanism of the packaging machine of the present invention, in order to meet different usage requirements, the structure of the discharge piece can be adaptively adjusted, for example: the material trough can be a V-shaped groove or a square groove, and the groove direction of the material trough can be arranged perpendicular to the pushing direction of the discharge drive structure; in addition, the material trough can be set only on one side of the discharge piece, or the material trough can be staggered on both sides of the discharge piece, which can also play a role in accurately arranging products.

[0039] In other specific embodiments of the material arrangement mechanism of the packaging machine of the present invention, in order to simplify the structural complexity of the entire mechanism, the blowing structure can be replaced by a belt conveyor, and the belt conveyor is used to transport the material to the material trough of the discharge member. In addition, the discharge drive structure and the blocking drive structure are not limited to cylinders, but can also be electric push rods, etc.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
