Description

Technical Field

[0001] The invention belongs to the field of packaging machinery, in particular to a fixed-distance and fixed-speed feeding system for anti-stacking special-shaped bottles. Background Art

[0002] With the advancement of technology and the development of the industry, it has become an inevitable development trend for automated packaging equipment to replace manual packaging. In automatic packaging equipment, for glass bottles or porcelain packaging bottles commonly used for high-end liquid products such as liquor, fruit wine, and perfume, automatic conveyor lines are usually used to continuously convey the packaging bottles in automated processing, and then the packaging equipment will package them one by one. In this process, it is an indispensable step to separate and convey the packaging bottles on the conveyor line at equal distances. Before entering the processing equipment on the existing automatic production line, the packaging bottles on the conveyor line are stacked and waited in sequence, and then enter the processing equipment in batches for further processing. However, during this stacking and waiting process, there will be squeezing between the bottles, and the bottom transmission belt will work continuously, and there will also be friction between the bottom of the bottle and the transmission belt, especially for some special-shaped bottles, such as bottles with smaller bottoms, which may even tip over, causing certain scratches, abrasions, or even damage on the outer surface of the bottle, resulting in defective products and losses. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a fixed-distance and fixed-speed feeding system for special-shaped bottles with scientific structure, reasonable design and strong adaptability to prevent accumulation.

[0004] The present invention solves the technical problem by adopting the following technical solutions:

[0005] A fixed-distance and fixed-speed feeding system for anti-stacking special-shaped bottles, wherein a bottle feeding line is horizontally arranged, and the bottle feeding line carries and transports the packaging bottles at a uniform speed from front to back. The characteristics are: the feeding system is installed on one or both radial sides of the rear part of the bottle feeding line, the feeding system evenly divides the spacing between the packaging bottles and outputs them at a uniform speed, and the feeding system can adjust the length of the working section.

[0006] Moreover, the feeding system comprises a first movable pulley, a second movable pulley, a third movable pulley, a fixed roller and a synchronous belt, the fixed roller is vertically and axially installed at the rear end of the bottle feeding line, three slideways are arranged from the inside to the outside on the outside of the bottle feeding line in front of the fixed roller, the first movable pulley, the second movable pulley and the third movable pulley are sequentially installed on the three slideways from the inside to the outside, the first movable pulley, the second movable pulley and the third movable pulley can all be laterally moved and adjusted in the corresponding slideways, the synchronous belt is sequentially wound and installed on the first movable pulley, the second movable pulley, the third movable pulley and the side rim of the fixed roller; a plurality of groups of protrusions are evenly spaced on the surface of one side of the synchronous belt contacting the packaging bottle, and the synchronous belts of the feeding system on both sides of the bottle feeding line synchronously clamp the packaging bottle delivered from the front end.

[0007] Moreover, a visual probe is installed on the upper end of the first movable pulley.

[0008] Moreover, the protrusions are composed of two layers, an upper layer and a lower layer, which respectively support the upper and lower parts of the packaging bottle.

[0009] Moreover, the spacing between adjacent protrusions is the same as the spacing of the packaging bottles output required for production, and only one packaging bottle can be fed between adjacent protrusions.

[0010] Moreover, the bottle feeding line is controlled by a servo motor; a synchronous belt motor is installed on the fixed roller to drive the synchronous belt to rotate at a constant speed.

[0011] Moreover, the method for adjusting the length of the working section of the system is:

[0012] When the incoming materials on the bottle feeding line are dense, while the synchronous belt pushes the packaging bottles, the first movable pulley moves along the bottom slideway to the front of the bottle feeding line, so that the working section of the synchronous belt is extended;

[0013] When the incoming material is sparse, the first movable pulley moves along the bottom slideway to the rear of the bottle feeding line, and the working section of the synchronous belt is shortened;

[0014] When the first movable pulley moves laterally, the second movable pulley and the third movable pulley move synchronously on their respective tracks to ensure that the synchronous belt always remains in a tensioned state.

[0015] The advantages and positive effects of the present invention are:

[0016] 1. This system can effectively prevent the extrusion deformation and surface wear caused by the stacking of packaging bottles, effectively ensure the quality of product packaging, and ensure that the surface is intact without damage or scratches.

[0017] 2. This system can achieve good conveying effect for both standard bottles and special-shaped bottles, can be tilted to prevent wear, has good processing effect, and has a wide range of applications.

[0018] 3. This system can adaptively adjust the material swallowing speed according to the speed of the incoming materials on the production line, and automatically adjust the working position and distance in a larger range, so that no matter whether the incoming materials on the conveyor line are dense or sparse, it can actively and effectively cooperate, maintain the uniform output of the packaging bottles at equal distances, and there is no accumulation of incoming materials.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0023] A fixed-distance and fixed-speed feeding system for anti-stacking special-shaped bottles, wherein a bottle feeding line 2 is arranged horizontally, the bottle feeding line is controlled by a servo motor 1, and the bottle feeding line carries and uniformly conveys packaging bottles 3 from front to back, and feeding systems are symmetrically installed on both sides of the radial direction of the rear of the bottle feeding line, and the feeding systems on both sides act synchronously, uniformly separate the spacing between packaging bottles and output at a uniform speed;

[0024] The specific structure of the feeding system is shown in the attached drawings, including a first movable pulley 5, a second movable pulley 8, a third movable pulley 4, a fixed roller 9 and a synchronous belt 6. The fixed roller is vertically axially installed at the rear end of the bottle feeding line. Three slideways are arranged from the inside to the outside of the bottle feeding line in front of the fixed roller (the slideways are not shown in the figure). The first movable pulley, the second movable pulley and the third movable pulley are sequentially installed on the three slideways from the inside to the outside. The first movable pulley, the second movable pulley and the third movable pulley are respectively controlled to be able to move and adjust laterally in the corresponding slideways. As shown in the figure, the synchronous belt is sequentially wound and installed on the first movable pulley, the second movable pulley, the third movable pulley and the side rim of the fixed roller, and the synchronous belt is driven by a motor to rotate;

[0025] A section of the synchronous belt between the first movable pulley and the fixed roller is parallel to the bottle feeding line and close to the side edge of the bottle feeding line as the working section. Multiple groups of protrusions 7 are evenly spaced on the surface of the synchronous belt on the side that contacts the packaging bottle. The spacing between adjacent protrusions is the same as the spacing of the packaging bottle output required for production. The height of the protrusions is set according to the size of the packaging bottle, which is used to synchronously support the packaging bottle from the rear to effectively prevent it from tilting and tipping during movement, and ensure that the packaging bottles move synchronously with equal spacing. The protrusions are upper and lower layers, which respectively support the upper and lower parts of the packaging bottle to improve the tipping effect.

[0026] The synchronous belts of the feeding system on both sides of the bottle feeding line synchronously clamp the packaging bottles sent from the front end, and one packaging bottle can be fed between adjacent protrusion groups;

[0027] A visual probe (not shown in the figure) is installed on the upper end of the first movable pulley to automatically determine the position of the incoming material on the bottle feeding line, and the PLC control system makes adjustments.

[0028] Due to the uneven density of incoming materials, in order to ensure that the bottles can be delivered at equal spacing and at a uniform speed, this system can automatically adjust the length of the working section. When the incoming materials on the bottle delivery line are dense, while the synchronous belt pushes the bottles, the first movable pulley moves along the bottom slideway to the front of the bottle delivery line, extending the working section of the synchronous belt. The longest limit position is shown in the attached Figure 3As shown in the figure; when the incoming material is sparse, the first movable pulley moves along the bottom slideway to the rear of the bottle feeding line. At this time, the working section of the synchronous belt is shortened. The shortest limit position is shown in the attached figure. Figure 2 shown.

[0029] When the first movable pulley moves laterally, the second movable pulley and the third movable pulley move synchronously on their respective tracks to ensure that the synchronous belt always remains in a tensioned state.

[0030] In this embodiment, a synchronous belt motor is installed on the fixed roller to drive the synchronous belt to rotate at a constant speed. The first movable pulley, the second movable pulley, and the third movable pulley are respectively controlled by linear motors to move on their own tracks.

[0031] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
