Description

Technical Field

[0001] The present invention relates to the field of packaging machinery, in particular to a transporting and boxing component. Background Art

[0002] In the linear filling technology for cupped products, the cups ultimately need to be transported from the conveyor and boxed. Cups are usually boxed in single or multiple cups. The first type of technology uses robots to transport and box the cups, which is relatively expensive. The second type of technology uses an array of cup-grabbing components (claws, suction cups, etc.) to grab the cups and stack them in boxes. For example, this structure is used in the Chinese patent authorization announcement number CN102431677B, authorized on March 12, 2014, and entitled "An Automatic Cup Grabbing Mechanism in a Plastic Cup Case Packing Machine." This patent is also the most widely used handling and boxing technology.

[0003] In the second type of technology, to facilitate the cup grabbing components to grab cups from the conveying components, spacing is generally left between the cup grabbing components. This results in large gaps between the cups when the cup grabbing components move the cups into the box. As a result, during packing, the space utilization rate in the box is low, the stacking is unstable, and the cups are easily misplaced, and even the cups may fall over each other. Summary of the Invention

[0004] In response to the above-mentioned defects of the existing linear filling technology, the present invention provides a handling and packing component that can achieve the following technical effects: the spacing between the cup grabbing parts is adjustable, which not only makes it convenient for the cup grabbing parts to grab cups, but also reduces the spacing between the cup grabbing parts before packing, so that the cups are closer to each other, improving the space utilization rate in the box, stacking them tightly and not easily misplaced, and preventing the cups from collapsing.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a handling and packing component, comprising a top plate, a grab cup member, and a displacement assembly. The grab cup member is arrayed on the top plate in the horizontal and vertical directions, and the top plate is driven by the displacement assembly to perform linear reciprocating motion in the vertical and horizontal directions. It also includes a horizontal variable pitch assembly and a longitudinal variable pitch assembly. The top plate is provided with a carrier plate arranged in the horizontal direction, and the carrier plate is slidably mounted on the lower end of the top plate through a horizontal guide rail. The horizontal variable pitch assembly is mounted on the top plate and drives each carrier plate to perform linear motion of different distances in the horizontal direction. The grab cup member is arranged on the carrier plate in the longitudinal direction, and the grab cup member is slidably mounted on the lower end of the carrier plate through a longitudinal guide rail. The longitudinal variable pitch assembly is mounted on the carrier plate and drives each grab cup member to perform linear motion of different distances in the longitudinal direction.

[0006] In this technical solution, the conveying direction parallel to the cup is defined as the longitudinal direction, and the conveying direction perpendicular to the cup is defined as the transverse direction. The carriers are arranged transversely on the top plate, and the transverse variable distance assembly drives the carriers to slide on the transverse guide rails, and the sliding distances of the carriers are different, thereby shortening the transverse spacing between the carriers. Since the cup-grabbing parts are mounted on the carriers, the transverse variable distance assembly can shorten the transverse spacing between the cup-grabbing parts during operation, so that the cup-grabbing parts are brought closer to each other in the transverse direction. The cup-grabbing parts are arranged longitudinally on the carriers, and the longitudinal variable distance assembly drives the cup-grabbing parts to slide on the longitudinal guide rails, and the sliding distances of the cup-grabbing parts are different, thereby shortening the longitudinal spacing between the cup-grabbing parts, so that the cup-grabbing parts are brought closer to each other in the longitudinal direction. In summary, after the cup-grabbing parts grab the cups, before packing, the transverse and longitudinal variable distance assemblies can adjust the transverse and longitudinal spacing between the cup-grabbing parts, thereby shortening the transverse and longitudinal spacing between the cup-grabbing parts, thereby improving the space utilization rate in the box during packing, and the cups are stacked tightly and not easily misplaced, preventing them from collapsing.

[0007] The transverse pitch change assembly has a similar structure to the longitudinal pitch change assembly. Specifically, the transverse pitch change assembly includes a first drive cylinder, a first rocker arm, and a plurality of first connecting rods. One end of the first rocker arm is hinged to the top plate. The cylinder body of the first drive cylinder is hinged to the top plate. The piston rod of the first drive cylinder is hinged to the first rocker arm. The number of first connecting rods is determined by the number of carriers to be driven. One end of each first connecting rod is hinged to the rocker arm, and the other end of the first connecting rod is hinged to the corresponding carrier. When the piston rod of the first drive cylinder is extended or retracted, it drives the first rocker arm to rotate, driving the first connecting rods on the first rocker arm to move, thereby driving the carriers to slide. Due to the different lengths of the first connecting rods, the longer the first connecting rod, the shorter the sliding distance of the carrier. When the piston rod of the first drive cylinder is extended, the distance between the carriers increases, and when the piston rod of the first drive cylinder is retracted, the distance between the carriers decreases.

[0008] Given that there are a large number of grabbing cups arranged in the transverse direction, in order to avoid the first driving cylinder being loaded with too many loading plates and to avoid the first connecting rod being too long and affecting the transmission progress, two sets of transverse variable pitch components are arranged. The two sets of transverse variable pitch components are symmetrically arranged at the transverse ends of the grabbing cups, and each set of transverse variable pitch components controls half of the grabbing cups to perform opposite linear motion along the transverse direction.

[0009] The longitudinal pitch-changing assembly includes a second drive cylinder, a second rocker arm, and a plurality of second connecting rods. One end of the second rocker arm is hinged to the loading plate. The cylinder body of the second drive cylinder is hinged to the loading plate. The piston rod of the second drive cylinder is hinged to the second rocker arm. The number of second connecting rods is determined by the number of gripping members to be driven. One end of each second connecting rod is hinged to the rocker arm, and the other end of the second connecting rod is hinged to the corresponding gripping member. When the piston rod of the second drive cylinder is extended or retracted, it drives the second rocker arm to rotate, driving the second connecting rods on the second rocker arm to move, thereby driving the gripping members to slide. Due to the different lengths of the second connecting rods, the longer the second connecting rod, the shorter the sliding distance of the gripping member. When the piston rod of the second drive cylinder is extended, the distance between the gripping members increases, and when the piston rod of the second drive cylinder is retracted, the distance between the gripping members decreases.

[0010] In order to meet the lifting and translation capabilities of the top plate, the displacement assembly includes a lifting assembly and a translation assembly. The lifting assembly includes a base plate, a lifting cylinder, and a fixed frame. The top plate is connected to the lower end of the fixed frame. The cylinder body of the lifting cylinder is fixed to the base plate. The piston rod of the lifting cylinder is connected to the fixed frame or the top plate. The fixed frame is mounted on the base plate in a sliding manner. Specifically, a guide rod is provided on the fixed frame, and a sliding sleeve is provided on the base plate. The guide rod is arranged in the vertical direction and is slidably arranged in the sliding sleeve. The cooperation between the guide rod and the sliding sleeve increases the lifting stability of the fixed frame. When the piston rod of the lifting cylinder is extended and retracted, it drives the fixed frame to perform linear reciprocating motion in the vertical direction. The translation assembly includes a motor, a synchronous belt, and a slide rail. The synchronous belt is extended in the horizontal direction. The base plate is fixed to the straight section of the synchronous belt. The base plate is mounted on the slide rail in a sliding manner. When the motor drives the synchronous belt to operate, it drives the base plate to perform linear reciprocating motion in the horizontal direction on the slide rail, thereby enabling the top plate to obtain vertical and horizontal displacement capabilities.

[0011] To make the cups more compact when packed, the cup grabbing device includes a fixed plate, a limit plate, and several suction cups. The fixed plate is mounted on the loading plate in a sliding manner. The fixed plate and the limit plate are arranged above and below each other and connected by a vertically extending air guide rod. The suction cups are mounted on the limit plate and connected to the air guide rod by an air path. In the horizontal or vertical direction, the height of the upper limit plate of the middle cup grabbing device is higher or lower than the height of the upper limit plates of the cup grabbing devices on both sides. For example, if the height of the middle limit plate is higher than the height of the limit plates on both sides, after the suction cups grab the cups, the cups rest on the limit plates. Due to the height difference of the limit plates, the middle cup is higher than the cups on both sides. Therefore, when packing, the middle cup will rest on the edges of the cups on both sides, forming an overlapping relationship. This improves the space utilization rate in the box, and at the same time, the cups are more tightly packed together, less likely to tip over, and more impact-resistant.

[0012] In order to prevent the suction cup from scratching the box when working, the grab cup also includes a surround, which is arranged around the edge of the limit plate and surrounds the suction cup. The grab cup will open the box when working, and the up and down movement of the outer grab cup will scratch the box. After adding the surround, the surround is in surface contact with the inner wall of the box to prevent the box from being scratched.

[0013] The advantages of this invention are: 1) After the cup gripper grasps the cups, the transverse and longitudinal spacing between the grippers can be reduced before packing, through the adjustment of the transverse and longitudinal spacing components. This allows the cups to be brought closer together, thereby improving space utilization within the box during packing. The cups are stacked tightly and are not easily misplaced, preventing them from collapsing. 2) The adjacent limiting plates are arranged in a high and low position. During packing, the cup in the middle rests on the cups on either side, forming an overlapping relationship. This improves space utilization within the box, and at the same time, the cups are more tightly packed together, making them less likely to fall over and providing greater impact resistance.

Therefore, these terms should not be construed as limitations on the present invention.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Embodiments of the present invention:

[0025] like Figures 1 to 7 As shown in FIG, a transport and packing component includes a top plate 301, a gripping cup, a displacement component, and a distance-varying component. The gripping cup is arrayed on the top plate 301 in the horizontal and vertical directions. Figure 1 Taking the cup grabbing member array shown as an example, there are six cup grabbing members in each horizontal row and three in each vertical column (the number and arrangement of the cup grabbing members can be adjusted according to actual working conditions), and the top plate 301 is driven by the displacement assembly to perform linear reciprocating motion in the vertical and horizontal directions.

[0026] The displacement component includes a lifting component and a translation component.

[0027] The lifting assembly includes a base plate 302, a lifting cylinder 303, and a fixed frame 304. The top plate 301 is connected to the lower end of the fixed frame 304. The cylinder body of the lifting cylinder 303 is fixed on the base plate 302. The piston rod of the lifting cylinder 303 is connected to the fixed frame 304 or the top plate 301. The fixed frame 304 is installed on the base plate 302 in a sliding manner. Specifically, a guide rod 305 is provided on the fixed frame 304, and a sliding sleeve 306 is provided on the base plate 302. The guide rod 305 is arranged in the vertical direction and is slidably set in the sliding sleeve 306. The cooperation of the guide rod 305 and the sliding sleeve 306 increases the stability of the lifting of the fixed frame 304. When the piston rod of the lifting cylinder 303 is extended and retracted, it drives the fixed frame 304 to perform linear reciprocating motion in the vertical direction, so that the top plate 301 obtains the ability to displace in the vertical direction.

[0028] The translation assembly includes a motor 307, a synchronous belt 308, and a slide rail 322. The synchronous belt 308 is extended in the horizontal direction. The base plate 302 is fixed on the straight section of the synchronous belt 308. The base plate 302 is installed on the slide rail 322 in a sliding manner. When the motor 307 drives the synchronous belt 308 to operate, it drives the base plate 302 to perform a horizontal linear reciprocating motion along the slide rail 322, thereby enabling the top plate 301 to obtain horizontal displacement capability.

[0029] The pitch-changing component includes a transverse pitch-changing component and a longitudinal pitch-changing component.

[0030] The top plate 301 is provided with transversely arranged carriers 309, which are slidably mounted on the lower end of the top plate 301 via transverse guide rails 310. There are six carriers 309, and a transverse pitch-changing assembly is mounted on the top plate 301 to drive each carrier 309 to perform linear motion of varying distances in the transverse direction. Specifically, the transverse pitch-changing assembly includes a first drive cylinder 311, a first rocker arm 312, and a plurality of first connecting rods 313. One end of the first rocker arm 312 is hinged to the top plate 301, the cylinder body of the first drive cylinder 311 is hinged to the top plate 301, and the piston rod of the first drive cylinder 311 is hinged to the first rocker arm 312. The number of first connecting rods 313 is determined by the number of carriers 309 to be driven. One end of each first connecting rod 313 is hinged to the rocker arm, and the other end of the first connecting rod 313 is hinged to the corresponding carrier 309. When the piston rod of the first driving cylinder 311 is extended or retracted, the first rocker arm 312 is driven to rotate, thereby driving the first connecting rods 313 on the first rocker arm 312 to move, thereby driving the carrier plate 309 to slide. Since the lengths of the first connecting rods 313 are different, the longer the first connecting rod 313, the shorter the sliding distance of the carrier plate 309. When the piston rod of the first driving cylinder 311 is extended, the distance between the carrier plates 309 becomes larger, and when the piston rod of the first driving cylinder 311 is retracted, the distance between the carrier plates 309 becomes smaller. Given that there are a large number of grasping cup members arranged in the transverse direction, in order to prevent the first driving cylinder 311 from being loaded with too many carrier plates 309 and to prevent the first connecting rod 313 from being too long and affecting the transmission progress, two sets of transverse pitch-changing components are arranged. The two sets of transverse pitch-changing components are symmetrically arranged at the transverse ends of the grasping cup members. Each set of transverse pitch-changing components controls the grasping cup members on half of the side to move in opposite directions in the transverse direction. At this time, three first connecting rods 313 are installed on each first rocker arm 312. When the first driving cylinder 311 on each side is working, it drives three carrier plates 309 to move horizontally.

[0031] The gripping elements are arranged longitudinally on the carrier plate 309 and are slidably mounted on the lower end of the carrier plate 309 via longitudinal guide rails 323. Each carrier plate 309 has three gripping elements. The number of longitudinal pitch-changing assemblies, six in total, equals the number of carrier plates 309. These assemblies are mounted on the carrier plate 309 and drive each gripping element to perform linear motion of varying lengths along the longitudinal direction. Specifically, the longitudinal pitch-changing assembly includes a second drive cylinder 314, a second rocker arm 315, and a plurality of second connecting rods 316. One end of the second rocker arm 315 is hinged to the carrier plate 309. The cylinder body of the second drive cylinder 314 is hinged to the carrier plate 309. The piston rod of the second drive cylinder 314 is hinged to the second rocker arm 315. The number of second connecting rods 316 is determined by the number of gripping elements to be driven. Each second connecting rod 316 has one end hinged to the rocker arm, and the other end hinged to the corresponding gripping element. When the piston rod of the second driving cylinder 314 is extended or retracted, it drives the second rocker arm 315 to rotate, driving the second connecting rods 316 on the second rocker arm 315 to move, thereby driving the cup-grabbing parts to slide. Since the lengths of the second connecting rods 316 are different, the longer the second connecting rod 316, the shorter the sliding distance of the cup-grabbing parts. When the piston rod of the second driving cylinder 314 is extended, the distance between the cup-grabbing parts becomes larger, and when the piston rod of the second driving cylinder 314 is retracted, the distance between the cup-grabbing parts becomes smaller.

[0032] In order to make the cup 100 more compact when packed, as Figure 3 As shown in , the cup grabbing member includes a fixed plate 317, a limiting plate 318, and several suction cups 319. The number and arrangement of the suction cups 319 are determined by the cup combination. For example, a four-cup combination uses four suction cups 319 arranged in two rows and two columns. The fixed plate 317 is mounted on the loading plate 309 in a sliding manner. The fixed plate 317 and the limiting plate 318 are arranged up and down and connected by a gas guide rod 320 extending in the vertical direction. The suction cups 319 are mounted on the limiting plate 318 and establish an air path connection with the gas guide rod 320. In the horizontal or vertical direction, the height of the upper limit plate 318 of the middle cup grabbing member is higher or lower than the height of the upper limit plates 318 of the cup grabbing members on both sides. Figure 3 、 Figure 7 As shown in the figure, in the longitudinal direction, the height of the middle limiting plate 318 is higher than the height of the limiting plates 318 on both sides. For example, after the suction cup 319 absorbs the cup 100, the cup 100 rests on the limiting plate 318. Due to the height difference of the limiting plates 318, the middle cup 100 is higher than the cups 100 on both sides. Therefore, when packing, the middle cup 100 will be placed on the edges of the cups 100 on both sides to form an overlapping relationship, which improves the space utilization rate in the box. At the same time, the cups 100 are more tightly packed, less likely to fall over, and have stronger impact resistance.

[0033] In order to prevent the suction cup 319 from scratching the box when working, the grab cup member also includes a surrounding plate 321. The surrounding plate 321 is arranged around the edge of the limit plate 318 and surrounds the suction cup 319. The grab cup member will open the box when working. When the outer grab cup member moves up and down, the limit plate 318 and the suction cup 319 will scratch the box and cause damage to the box. After adding the surrounding plate 321, the surrounding plate 321 will make surface contact with the inner wall of the box when the grab cup member moves, which has a buffering effect to prevent the box from being scratched and damaged.

[0034] In this embodiment, the conveying direction parallel to the cup 100 is defined as the longitudinal direction, and the conveying direction perpendicular to the cup 100 is defined as the transverse direction. The structures of the transverse pitch-changing assembly and the longitudinal pitch-changing assembly are similar. The carrier plates 309 are arranged in the transverse direction on the top plate 301. The transverse pitch-changing assembly drives the carrier plates 309 to slide on the transverse guide rails 310, and the sliding distances of the carrier plates 309 are different, thereby shortening the transverse spacing between the carrier plates 309. Since the cup-grabbing members are installed on the carrier plates 309, the transverse pitch-changing assembly can shorten the transverse spacing between the cup-grabbing members during operation, so that the cup-grabbing members are brought closer to each other in the transverse direction. The cup-grabbing members are arranged in the longitudinal direction on the carrier plates 309. The longitudinal pitch-changing assembly drives the cup-grabbing members to slide on the longitudinal guide rails 323, and the sliding distances of the cup-grabbing members are different, thereby shortening the longitudinal spacing between the cup-grabbing members, so that the cup-grabbing members are brought closer to each other in the longitudinal direction. In summary, the lifting group will enable the cup grabbing member to obtain the ability to move in the horizontal and vertical directions. After the cup grabbing member grabs the cup 100, before packing, the horizontal and vertical spacing of the cup grabbing member can be reduced through the adjustment of the horizontal and vertical spacing components, so that the cups 100 are closer to each other, so as to improve the space utilization rate in the box during packing. The cups 100 are stacked tightly and not easily misplaced, preventing them from crushing each other.

[0035] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above invention, which fall within the scope of protection of the present invention.
