Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying, and in particular relates to packaging box palletizing and conveying equipment. Background Art

[0002] When palletizing boxes, it is necessary to use feeding equipment to automatically load the boxes, transport the boxes to the workstation of the palletizer, and cooperate with the palletizer to complete automatic palletizing.

[0003] The width of existing conveying equipment is usually fixed. During transportation, the packaging boxes should be placed in the middle area of the conveying equipment as much as possible so that the packaging boxes are transported along the center line of the conveying equipment. In this way, the downstream palletizer can position the clamps on the packaging boxes more quickly during palletizing. However, for packaging boxes of different sizes, especially smaller packaging boxes, it is difficult to keep them on the center line of the conveying equipment during transportation, which reduces the efficiency of the downstream palletizer and easily causes the packaging boxes to accumulate on the conveying equipment.

[0004] In view of this, the inventors conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0005] The purpose of the utility model is to provide a packaging box stacking and conveying device, which can adapt to packaging boxes of different volumes and keep the packaging boxes in the center position for conveying.

[0006] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0007] A packaging box palletizing and conveying equipment includes a conveyor frame, a plurality of conveyor rollers are provided on the conveyor frame, and a limiting mechanism installed on the conveyor frame. The limiting mechanism includes two limiting members respectively installed on both sides of the conveyor frame and an adjustment component for driving the two limiting members to move closer to or away from each other. The limiting member has a limiting plate located above the conveyor roller, a guide plate, a driving plate located below the conveyor roller, and a connecting frame connecting the limiting plate and the driving plate; the guide plate is fixedly connected to the front end of the limiting plate, and the distance between the two guide plates gradually increases from the side close to the limiting plate to the side away from the limiting plate.

[0008] Furthermore, the conveyor frame is provided with two mounting plates, one on each side of the conveyor frame and below the conveyor roller. A plurality of guide rods are provided between the two mounting plates. The drive plate is provided with guide holes that slidably engage with the guide rods. The adjustment assembly includes an adjustment screw and a first motor that drives the adjustment screw. The adjustment screw is rotatably mounted on the mounting plates, and the drive plate is provided with a threaded hole that engages with the adjustment screw. The adjustment screw allows for more precise adjustment of the spacing between the two limit plates, and the guide rods allow for smoother movement of the limiter.

[0009] Furthermore, the guide plate is equipped with an adjustment assembly for shifting the packaging box toward the center. The adjustment assembly includes multiple eccentric wheels rotatably mounted on the guide plate and a second motor that drives the eccentric wheels. The guide plate is formed with a clearance groove for the eccentric wheels to rotate. The adjustment assembly can be used to shift the packaging box toward the center, allowing it to pass more quickly between the two stop plates.

[0010] Furthermore, the guide plate has support plates at the upper and lower ends thereof for mounting the eccentrics, and the second motor is fixedly mounted on the top of the support plate above. A first pulley is provided on the rotating shaft of the eccentric, and the first pulleys of the eccentrics on the same side are connected by a first synchronous belt. The first synchronous belt can simultaneously drive the rotation of multiple eccentrics.

[0011] Furthermore, the conveyor frame is equipped with a third motor that drives the plurality of conveyor rollers. Sprockets are mounted on the rotating shafts of the conveyor rollers, and the plurality of conveyor rollers are connected by a chain. A second pulley is mounted on the rotating shaft of the conveyor roller at the head end, and a third pulley is mounted on the output shaft of the third motor. A second synchronous belt is mounted on the third pulley and the second pulley. Using sprockets to drive the conveyor rollers reduces kinetic energy loss and transmits greater power.

[0012] Furthermore, a discharge area is formed at the rear end of the conveyor frame, and photoelectric switches are provided on both sides of the discharge area; the photoelectric switches are fixedly mounted on both sides of the conveyor frame. The photoelectric switches can accurately sense whether the packaging box has reached the discharge area.

[0013] After adopting the above structure, the utility model involves a packaging box stacking and conveying equipment. Compared with the existing technology, this case installs a limiting mechanism on the conveying frame, and uses the adjustment component in the limiting mechanism to move the limiting part from both sides of the conveying frame to adjust the distance between the two limiting plates. In addition, a guide plate is provided at the front end of the limiting plate, and the guide plate extends to both sides of the conveying frame. During transportation, the packaging boxes can be gathered to the middle through the guide plate, which speeds up the passage of the packaging boxes and improves the overall transportation efficiency.

DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts in the drawings or in the specification are numbered the same. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back" mentioned in the embodiments are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0023] like Figures 1 to 6As shown, a packaging box palletizing and feeding equipment involved in the present invention includes a conveying frame 1, on which a plurality of conveying rollers 11 are provided, and a limiting mechanism 2 that can be adjusted according to the size of the packaging box is also provided on the conveying frame. The limiting mechanism 2 includes two limiting members 21 respectively installed on both sides of the conveying frame 1 and an adjusting component 22 that drives the two limiting members 21 to move closer to or away from each other. The limiting member 21 has a limiting plate 211 located above the conveying roller 11, a guide plate 212, a driving plate 213 located below the conveying roller 11, and a connecting frame 214 connecting the limiting plate 211 and the driving plate 213; the guide plate 212 is fixedly connected to the front end of the limiting plate 211, and the distance between the two guide plates 212 gradually increases from the side close to the limiting plate 211 to the side away from the limiting plate 211. Specifically, two mounting plates 12 are provided on the conveying frame 1, and the two mounting plates 12 are respectively located on both sides of the conveying frame 1 and below the conveying roller 11; a plurality of guide rods 121 are also provided between the two mounting plates 12; a guide hole 2131 is formed on the driving plate 213, which slides with the guide rod 121; the adjusting assembly 22 includes an adjusting screw 221 and a first motor 222 for driving the adjusting screw 221 to rotate, and the adjusting screw 221 is rotatably mounted on the mounting plate 12, and a threaded hole 2132 is also formed on the driving plate 213, which cooperates with the adjusting screw 221. The adjusting screw 221 has two threaded sections with opposite thread directions, and the threaded holes 2132 on the two drive plates 213 respectively cooperate with the corresponding threaded sections; the adjusting screw 221 can be used to more accurately adjust the distance between the two limit plates 211, and through the guide rod 121, the limit member 21 can be made more stable when moving. In addition, the drive plate 213 is arranged below the conveyor roller 11 to avoid interference between the adjusting screw 221 and the guide rod 121 on the packaging box.

[0024] Preferably, the guide plate 212 is provided with an adjustment assembly 3 for shifting the packaging box toward the center. The adjustment assembly 3 includes a plurality of eccentric wheels 31 rotatably mounted on the guide plate 212 and a second motor 32 that drives the eccentric wheels 31. The guide plate 212 is formed with a clearance groove 2121 for the eccentric wheels 31 to rotate. During transportation, some heavy products may be blocked by the resistance of the guide plate 212 if they come into contact with the guide plate 212, preventing the conveyor roller 11 from continuing to convey the packaging box forward. Therefore, the adjustment assembly 3 can be used to shift the packaging box toward the center, preventing direct contact between the guide plate 212 and allowing the packaging box to pass more quickly between the two limit plates 211.

[0025] Preferably, support plates 2122 for mounting the eccentrics 31 are provided at the upper and lower ends of the guide plate 212, and the second motor 32 is fixedly mounted on the top of the support plate 2122. A first pulley 311 is provided on the rotating shaft of the eccentric 31, and the first pulleys 311 of the eccentrics 31 on the same side are connected by a first synchronous belt 33. The first synchronous belt 33 can simultaneously drive multiple eccentrics 31 to rotate, and ensure that the multiple eccentrics 31 rotate in the same direction, making it easier to move the packaging box to the center.

[0026] Preferably, the conveyor frame 1 is further provided with a third motor 4 that drives the plurality of conveyor rollers 11. Sprockets are provided on the rotating shafts of the conveyor rollers 11, and the plurality of conveyor rollers 11 are connected by a chain. A second pulley 111 is provided on the rotating shaft of the conveyor roller 11 at the head end. A third pulley 41 is provided on the output shaft of the third motor 4. A second synchronous belt 42 is provided between the third pulley 41 and the second pulley 111. Using sprockets to drive the conveyor rollers 11 reduces kinetic energy loss and transmits greater power.

[0027] A discharge area 13 is formed at the rear end of the conveyor frame 1. Photoelectric switches 5 are fixedly mounted on either side of the conveyor frame 1. The photoelectric switches 5 detect when a package box has reached the discharge area 13. At this point, the third motor 4 is stopped. After the palletizing robot grabs the box, the photoelectric switches 5 control the third motor 4 to continue running, causing the conveyor rollers 11 to continue rotating and conveying the box.

[0028] The method of using the present invention is as follows: first, adjust the distance between the two limit plates 211 according to the size of the packaging box to be transported and palletized. During the transportation process, place the packaging box on the conveying roller 11, and use the conveying roller 11 to transport the packaging box. The packaging box will first pass through the guide plate 212. Under the action of the adjustment component 3 of the guide plate 212, the packaging box that deviates from the center of the conveying roller 11 can be straightened to the middle, and then enter between the two limit plates 211. Under the action of the limit plates 211, the packaging box will continue to be transported along the center of the conveying roller 11 until it is transported to the unloading area 13 at the end of the conveying frame 1, and is removed by the palletizer for palletizing.

[0029] The above describes in detail the palletizing and conveying equipment for packaging boxes provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the claims of the present invention.
