Description

Technical Field

[0001] The invention belongs to the technical field of packaging machinery, and in particular relates to an anti-overturning feeding device and a trimming and moulding device. Background Art

[0002] After research, the inventor found that on the automated production line of packaging boxes, the problem of loading small box materials is an issue that needs to be solved urgently.

[0003] In the production process of a small packaging box, an inner mold is first used to support the inside to form an inner box, and then the outer surface is covered with outer paper. The outer box is then opened, trimmed and demolded. In other words, the outer paper on the side of the outer box is cut with a cutter to take out the inner mold that supports the inside. On the existing production line, the hopper for the trimming and demolding device is usually loaded by manual stacking. If the thickness of an inner box is 15 mm, a 1-meter-high hopper can stack 66 boxes. Calculated based on the output efficiency of pushing out one box per second, a full hopper will be emptied in 66 seconds. If a person stays behind to work without stopping the machine, it will take about 1 minute to fill the hopper. Otherwise, the equipment's rhythm will be disrupted and the machine will stop, affecting production efficiency.

[0004] Raising the height of the silo is one way to solve the problem, but the height requirement of the equipment in the workshop cannot be too high. Usually, about 1.3 meters is the height that can be touched by human hands during normal work, so this method is not very effective.

[0005] The inventors then developed a loading device that could stack multiple rows of small boxes at once, then separate a single row of materials, and then separate a vertical column of materials from the single row into the equipment's hopper, achieving non-stop loading. However, this solution is not suitable for materials with smooth surfaces because the individual materials are small, and if a row of materials is moved as a whole, the entire row or part of it will collapse. Summary of the Invention

[0006] Based on the above background, the technical problem to be solved by the present invention is to provide an anti-fall loading device that can prevent smooth materials from collapsing, thereby reducing labor costs and improving production efficiency. At the same time, another technical problem to be solved by the present invention is to provide a trimming and mold removal device that can greatly reduce labor costs when loading boxes with any smooth surface into the device, thereby improving the reliability of the device.

[0007] The present invention is implemented like this:

[0008] The anti-reverse loading device includes a conveyor belt module, and a material pushing mechanism is arranged above the conveyor belt module. The characteristic is that the material pushing mechanism includes a first baffle and a support plate that are arranged obliquely, and a space for storing materials in a whole row is formed between the first baffle and the support plate. A discharge port is opened at the angle between the first baffle and the support plate; and a push plate is arranged on one side of the discharge port, and the push plate has a stroke of reciprocating movement through the discharge port; a second baffle is arranged on the other side of the discharge port.

[0009] Furthermore, the support plate and the conveyor belt module are connected via a bracket, and the bracket has two arms, and the angle between the two arms is an obtuse angle.

[0010] Furthermore, one side of the conveyor belt is connected to the support plate, and the other side is provided with the second baffle.

[0011] Furthermore, a soft material is provided on the bottom of the first baffle and / or the upper surface of the supporting plate so that the discharge port forms an irregular contour.

[0012] Furthermore, a movable clapper is provided on the side of the space for clapping the material in the space.

[0013] Furthermore, a table with a telescopic stroke is provided between the discharge port and the second baffle.

[0014] Furthermore, the second baffle is provided with an opening that cooperates with the telescopic stroke, the table top passes through the opening, one end of which can be advanced to the oblique lower side of the discharge port, and the other end of which is fixedly connected to the conveyor belt module through a sliding module.

[0015] Furthermore, a guide plate with smooth edges is provided above the table top.

[0016] Furthermore, one side of the silo is connected to any of the above-mentioned anti-overturning feeding devices through a guide platform, and materials can be transported from the space to the silo.

[0017] Furthermore, a bell mouth is provided at one end of the guide platform, and a pressing block that can be pressed downward is provided above the other end.

[0018] Compared with the prior art, the anti-overturning feeding device provided by the present invention has the following beneficial effects:

[0019] (1) A whole row of materials can be placed in the space of this device. Even if the surface of the materials is relatively smooth, they can still maintain the stacking state by relying on the inclined first baffle and their own gravity.

[0020] (2) This device can push out the bottom material in the whole row of materials under the joint action of the push plate and the second baffle, so that it is pushed out along the discharge port and blocked and then falls onto the conveyor belt module, thereby facilitating manual maintenance of the full load state of the feeding end and freeing up more manual labor.

[0021] (3) This device adopts a commonly used conveyor belt module, which has wide versatility and can be easily expanded to other equipment as a supporting device.

[0022] The trimming and moulding device provided by the present invention has the following beneficial effects compared with the prior art:

[0023] (1) The loading process of the trimming and moulding device is simpler and the degree of manual labor dependence is further reduced.

[0024] (2) Compared with other existing box material conveying methods on the market, this device can store box materials in a three-dimensional space, occupying a smaller area and having a larger storage capacity.

[0025] (3) The device is horizontally arranged with the length surface of the box material as the bottom surface, and the box material is horizontally discharged into the outer box material bin. The posture and angle of the box body do not change, thereby improving the stability during the material transfer process. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0035] In the manufacturing process of packaging boxes, some box types require the inner box as a mold to achieve overmolding of the outer paper. The outer paper of the outer box is then cut along three continuous edges to remove the inner mold. The outer box's box specifications are usually square semi-finished products with a length and / or width of approximately 55-105 mm and a height of approximately 15-30 mm. The outer paper is made of pre-printed wrapping paper, and the outer surface is usually a polypropylene film with high smoothness. During the mass production of packaging boxes, if a small amount of outer box semi-finished products are stacked in the small silo of certain equipment, the risk of collapse, falling, and collision due to material stacking is very small, but the production capacity will be limited by labor. In order to ensure that production capacity is not limited and to free up labor, it is necessary to improve the loading method of the semi-finished products. Example 1

[0036] See also Figure 1 and Figure 2 This solution is designed for smoother box materials and has the effect of preventing overturning and batch output.

[0037] The device consists of a conveyor belt module 10 and a material pushing mechanism. When materials are manually placed in the material pushing mechanism and filled with several piles and laid out into a whole row, the material pushing mechanism can push materials out layer by layer from the bottom layer in the whole row.

[0038] Figure 2 In the embodiment, the conveyor belt module includes a conveyor belt, a motor, and a frame. The upper layer of the conveyor belt is the flow channel for transferring materials. The material pushing mechanism includes a first baffle 31, a support plate 21, and a material pushing assembly. The first baffle 31 and the support plate 21 are both tilted, and the angle between the first baffle 31 and the support plate 21 is a right angle. The space 50 formed between the two is open and convenient for adapting to the box body. The box body is stacked on the support plate 21 from the bottom up, and the entire first baffle 31 is piled up to fill the space 50. Specifically, the support plate 21 is fixedly connected to the conveyor belt module 10 by a bracket 23. The bracket has two arms, and the angle between the two arms is an obtuse angle to keep the support plate 21 tilted.

[0039] A discharge port is provided at the angle between the first baffle 31 and the support plate 21. Specifically, the first baffle 31 is secured to the support plate 21 via right-angle brackets on its left and right sides, with a gap provided between the support plate 21 and the first baffle 31. This forms a discharge port 51. A pusher assembly is provided on one side of the discharge port 51, comprising a pusher plate 41, a cover plate 42, a connector, and a drive assembly, the drive assembly being a cylinder 44 and a slide rail and slider module 43. The cylinder is fixed to the bottom surface of the support plate 21, which has two chutes 22 formed therein. Connectors extend from the two chutes 22 to connect to the pusher plate 41. The drive assembly drives the pusher plate 41 back and forth along the chutes 22 via the connector. As the push plate 41 moves toward the discharge port, it pushes the bottom layer of material 8, pushing the entire layer out of the discharge port. The penultimate layer falls onto the push plate 41 and is located in the space between the cover plate 42 and the first baffle 31. When the push plate 41 retracts, the material is restrained by the cover plate 42, overcoming the static friction of the push plate 41 until the push plate 41 is completely retracted below the cover plate 42. The material falls and contacts the support plate 21, and the cycle repeats. The material pushed out of the discharge port is blocked by the second baffle 32 and falls to the upper layer of the conveyor belt by its own gravity.

[0040] Generally, due to the static friction between the material on the bottom layer and the support plate 21, if there is no thrust at the discharge port, the material 8 will not automatically slide out of the discharge port 51. However, there are exceptions. When the outer surface of the material is sufficiently smooth and the angle of inclination of the support plate 21 and the first baffle 31 is close to 45°, the material may automatically slide out. If this happens, it will disrupt the normal operation of the equipment. Therefore, it is possible to add a speed bump at the discharge port 51, such as placing a soft material such as a brush, sponge, or leather at the bottom of the first baffle 31, or to add an arc-shaped protrusion, sponge, or leather on the support plate 21 to give the discharge port 51 an irregular contour to prevent the material from automatically sliding out.

[0041] The two sides of the space 50 can be defined by fixed side baffles 33, and a cylinder and a clapper 34 can be set next to one side baffle to realize automatic sorting of stacked materials. Example 2

[0042] like Figure 3 and Figure 4 The arrangement of this solution is generally the same as that of the first embodiment, but the falling method after the material 8 is discharged from the discharge port 51 is further optimized, so that the material 8 is first received and then falls freely.

[0043] Specifically, a retractable tabletop 60 is positioned between the second baffle 32 and the discharge port 51. The second baffle 32 has an opening, and a slide rail and slider module 43 is also positioned on one side of the second baffle 32. A cylinder 44 passes through the interlayer of the conveyor belt and connects to the tabletop 60 via another connector. The slide rail is secured to the other side of the conveyor belt via a triangular bracket 61, and the slider is connected to the tabletop 60, allowing the tabletop 60 to extend and retract along the opening. When material 8 is pushed out of the discharge port 51 and received by the extended tabletop 60, the slide rail and slider module 43 retracts the tabletop 60. The material 8, under the dual action of the tabletop 60 and the second baffle 32, is further organized and falls onto the conveyor belt.

[0044] If the material 8 is light, it may flip due to inertia or airflow during ejection, disrupting the normal rhythm of subsequent processes and resulting in defective products. Therefore, a guide plate 64 is provided parallel to the table 60 to limit the material. The guide plate 64 is interposed with the table 60 to form a gap. The table 60 is retractable, and the guide plate 64 is fixed to the second baffle 32.

[0045] Example 3

[0046] Existing trimming and mold removal devices (also known as carton openers) utilize a parabolic track and conveyor belt at the front of the hopper to queue and drop a row of box materials. The boxes are lined up at the front of the parabolic track, with their thickness as the bottom surface. The conveyor belt carries the boxes through a parabola, then drops them horizontally into the hopper. In actual workshop operations, the last box on the parabolic track at the front is often unstable due to inertia and requires manual support.

[0047] In order to increase production capacity and discharge one box per second, this method can only infinitely lengthen the horizontal section of the conveyor belt at the front end of the parabolic track.

[0048] like Figure 5 The present invention provides a trimming and molding device, which is equipped with an outer box silo 7. Any anti-falling feeding device in the above-mentioned embodiments is grafted into the outer box silo 7 through a guide platform 12, and the material 8 is placed in the space 50 to realize the feeding step of the device. The box bodies are horizontally laid out with the length surface as the bottom surface in the space 50, and stacked into rows, and then pushed out in layers, and then moved horizontally to the guide platform 12 via a conveyor belt. The guide platform 12 is inserted from the waist of the outer box silo 7. The posture and angle of the box body always remain unchanged, and there is no risk of turning over the box. The space 50 realizes the three-dimensional storage of the box body. Under the same floor space, the number of box bodies that can be stored in the present invention is doubled, and the posture of the box body is stable, which realizes the real liberation of labor.

[0049] The guide platform 12 is groove-shaped and has a channel. One end of the channel is flared and connected to the discharge end of the conveyor belt 11, and the other end leads to the upper middle portion of the outer box silo 7. A cylinder and a pressure block are vertically positioned above this end to intercept the output material. Therefore, the present invention also includes a method for controlling the delivery of outer box material by trimming and taking a mold:

[0050] The outer box material 8 moves to the guide table 12, and queues up from the bell mouth and enters the above-mentioned channel in turn;

[0051] A cut-off position is provided at the end of the channel, and a vertical cylinder 44 is provided above the cut-off position. A pressure block is connected to the telescopic rod of the cylinder 44. A sensor cooperating with the cylinder is provided above the outer box silo 7 to detect the presence of the inner and outer box materials 8 in the silo.

[0052] When it is detected that there is an outer box material 8 in the outer box granary 7, the telescopic rod of the control cylinder 44 is extended, and the pressure block cuts off the outer box material 8 at the cut-off position, and the outer box material required later is accumulated in the rear section;

[0053] When it is detected that there is no outer box material 8 in the outer box silo 7, the telescopic rod of the control cylinder 44 is returned to its original position and retracted, and the outer box material 8 is released and flows into the outer box silo 7 for replenishment.

[0054] The method can effectively control the flow rhythm of the material, so that the material in the silo of the trimming and moulding device will not be excessively accumulated.

[0055] Example 4

[0056] In the first embodiment of the present invention, a soft material is used to define the contour of the discharge port 51 to prevent the material from automatically sliding out and affecting the beat. This embodiment provides a more stable and durable solution.

[0057] A plurality of hinges 52 and a movable baffle 53 are provided at the bottom of the back of the first baffle 31. One hinge 52 is fixed above the discharge port 51, and the other hinge 52 is connected to the movable baffle 53. When the push plate 41 pushes the material toward the discharge port 51 under the action of the cylinder 44, the material pushes the movable baffle 53 to flip, and the material is pushed out.

[0058] Optionally, the movable baffle 53 is a straight long plate or a corner plate folded into a right angle.

[0059] Furthermore, in the case of a corner plate, a counterweight block can be fixed on one of the side surfaces to increase the turning force of the movable baffle 53.
