Description

Technical Field

[0001] The present invention relates to the technical field of packaging, in particular to a grouping device. Background Art

[0002] Long, vertically arranged items (e.g., elongated cola cans, tall glass bottles) placed on a conveyor belt have a higher center of gravity than flat, horizontally placed items. Items on the conveyor belt are grouped according to packing specifications, forming a matrix arrangement. Conventional technology typically uses a first and a second conveyor belt to coordinate the grouping process: the first conveyor belt transports the continuously arranged items, while the second conveyor belt transports the grouped, matrix-arranged items. During grouping, the first and second conveyor belts operate, with the first conveyor belt transferring the items to the second conveyor belt. The first conveyor belt then stops, while the second conveyor belt continues moving, separating the items on the first and second conveyor belts and achieving the grouping effect. Finally, the second conveyor belt stops, and a bottle grabber removes the grouped items from the second conveyor belt. However, the high center of gravity of the items means that both the continuously arranged and the grouped, matrix-arranged items will tip over due to inertia when they stop. This is particularly pronounced when the items are moving at high speeds, making grouping only possible at low conveyor speeds. Summary of the Invention

[0003] In order to solve the shortcoming of the existing grouping method that the articles are easy to fall over, the present invention provides a grouping device, which prevents bottles from falling over.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] The bottle conveyor belt is a bottle conveyor belt of claim 1, wherein the bottle conveyor belt is a bottle conveyor belt of the plurality of bottles. The bottle conveyor belt is a bottle conveyor belt of the plurality of bottles. The bottle conveyor belt is a bottle conveyor belt of the plurality of bottles. The conveyor belt is used to support the wheel group of the first conveyor belt, the wheel group includes a first pulley, a second pulley, a third pulley and a fourth pulley, the first pulley is rotatably connected to one side of the support plate, the second pulley and the third pulley are rotatably connected to the lower end of the first side plate, and the fourth pulley is rotatably connected to the upper end of the first side plate, the first pulley, the second pulley and the fourth pulley are located at the inner side of the first conveyor belt, and the third pulley is located at the outer side of the first conveyor belt so that the first conveyor belt is L-shaped. The first conveyor belt includes a first section arranged between the third pulley and the first pulley, and a second section arranged between the third pulley and the fourth pulley. The first side plate is provided with a first motor, and the first motor is connected to the fourth pulley through a rotating shaft to drive the rear guard rod to move along the first conveyor belt. When the rear guard rod moves upward along the second section, the height of the rear guard rod increases to prevent interference between the rear guard rod and the bottle. When the rear guard rod moves downward along the second section, the rear guard rod groups the bottles. When the rear rod moves toward the first pulley along the first section, the rear rod pushes the grouped bottles to move along the support plate.

[0006] Through the above arrangement, the bottles of the present application are not easy to fall over when grouping the bottles. Specifically, the progressive conveying mechanism conveys the bottles that are close to each other to the grouping conveying mechanism. Specifically, the bottles that are close to each other are placed vertically on the conveyor belt. Under the action of the first driving device, the conveyor belt runs and conveys the bottles to the right. At this time, under the action of the fourth driving device, the front baffle is located at the left end of the support plate and is ready to receive the bottles. The rear baffle is located on the second section, thereby preventing the bottles from interfering with the rear baffle when moving along the support plate. The left end of the support plate is close to the right end of the conveyor belt, and the upper side of the support plate is basically flush with the upper side of the conveyor belt, so that The bottles can move from the conveyor belt to the support plate. When the bottles move to the right end of the conveyor belt, as the conveyor belt continues to run, the bottles continuously slide from the left end of the support plate to the support plate. When the bottles move to the front baffle, the fourth drive device runs and drives the front baffle to move to the right, and the front baffle moves to the right synchronously with the bottles. When the number of bottles on the support plate reaches the preset value, under the action of the second drive device, the extruder moves downward and presses the bottle at the rightmost end of the conveyor belt onto the conveyor belt. At the same time, the first drive device stops moving, and the conveyor belt and the bottles on the conveyor belt stop moving to the right. Since the extruder presses the bottle at the rightmost end of the conveyor belt, Therefore, when the bottle stops moving to the right, the bottle at the rightmost end of the conveyor belt will not fall to the right due to inertia. Since the bottles on the conveyor belt are close to each other, the bottles on the conveyor belt will not fall when it stops moving. Then, under the action of the first motor, the shaft drives the first conveyor belt to run through the fourth pulley, and the rear block moves downward along the second section and moves between adjacent bottles to group the bottles. At this time, the rear block is located at the lower end of the second section. Then, as the first conveyor belt continues to run, the first conveyor belt drives the rear block to pass from the lower side of the third pulley, and then the rear block moves to the right along the first section and pushes the grouped bottles along the support plate Continue to move to the right. During this process, the front baffle moves to the right with the grouped bottles under the action of the fourth drive device. When the rear baffle moves to the right end of the first section, the rear baffle and the front baffle both stop moving. The front baffle prevents the grouped bottles from tipping over under the action of inertia when they stop moving. Then the first motor runs in reverse, and the rear baffle returns to the upper end of the second section under the action of the first conveyor belt. Then the existing bottle grabbing device takes the grouped bottles off the support plate. Then the front baffle moves to the left to the left end of the support plate under the action of the fourth drive device. At this point, the application returns to the initial state, and the above steps can be repeated to carry out the next round of grouping.

[0007] Furthermore, both ends of the third pulley are provided with limiting protrusions along the circumferential direction to prevent the first conveyor belt and the third pulley from being disengaged, and the limiting protrusions are provided with avoidance grooves for avoiding the rear barrier rod.

[0008] Furthermore, second side plates are provided on opposite sides of the conveyor belt in the width direction, and support rollers for supporting the conveyor belt are rotatably connected between the second side plates. The first driving device includes a driving wheel abutting the conveyor belt and a second motor connected to the driving wheel.

[0009] Furthermore, the second drive device includes screw rods arranged at both ends of the top plate and a third motor connected to one of the screw rods. The upper end of the screw rod passes through the top plate and is rotatably connected to the top plate. The upper end of the screw rod is fixedly connected to a synchronous wheel, and the synchronous wheels are connected by a synchronous belt. The screw rod extends vertically and is threadedly connected to the end of the extrusion member.

[0010] Furthermore, a connecting plate is fixedly connected to one side of the first side plate close to the other first side plate, the lower end of the screw rod is rotatably connected to the connecting plate, and a guide column extending vertically is fixedly connected between the connecting plate and the top plate, and the guide column passes through the extrusion piece and is slidably connected to the extrusion piece.

[0011] Furthermore, the fourth driving device includes a second conveyor belt arranged on opposite sides of the width direction of the support plate, and a fourth motor for driving the second conveyor belt to operate. The second conveyor belt extends along the length direction of the support plate. A mounting beam is arranged between the second conveyor belts.

The third driving device includes a first conveyor belt 1231 provided at both ends of the rear baffle 122, a wheel group for supporting the first conveyor belt 1231, and the wheel group includes a first pulley 1232, a second pulley 1233, a third pulley 1234, a fourth pulley 1235, a fourth pulley 1236, a fifth pulley 1247, a fifth pulley 1248, a fifth pulley 1249, a fifth pulley 1251, a fifth pulley 1260, a fifth pulley 1261, a fifth pulley 1262, a fifth pulley 1263 The second pulley 1233, the third pulley 1234 and the fourth pulley 1235, the first pulley 1232 is rotatably connected to one side of the support plate 121, the second pulley 1233 and the third pulley 1234 are rotatably connected to the lower end of the first side plate 1131, and the fourth pulley 1235 is rotatably connected to the upper end of the first side plate 1131. The first pulley 1232, the second pulley 1233 and the fourth pulley 1235 are located on the inner side of the first conveyor belt 1231, and the third pulley 1234 is located on the outer side of the first conveyor belt 1231, so that the first conveyor belt 1231 is L-shaped. The first conveyor belt 1231 includes a first section 12311 arranged between the third pulley 1234 and the first pulley 1232, a first section 12312 arranged between the third pulley 1234 and the first pulley 1232, and a 234 and the fourth pulley 1235, the first side plate 1131 is provided with a first motor 1132, and the first motor 1132 is connected to the fourth pulley 1235 through the rotating shaft 1133 to drive the rear bar 122 to move along the first conveyor belt 1231, when the rear bar 122 moves upward along the second section 12312, the height of the rear bar 122 increases to prevent interference between the rear bar 122 and the bottles 21, when the rear bar 122 moves downward along the second section 12312, the rear bar 122 groups the bottles 21, and when the rear bar 122 moves along the first section 12311 toward the first pulley 1232, the rear bar 122 pushes the grouped bottles 21 to move along the support plate 121.

[0025] Through the above arrangement, the present application is not easy to tip over when the bottles 21 are grouped. Specifically, the progressive conveying mechanism 11 conveys the bottles 21 adjacent to each other to the grouping conveying mechanism 12. Specifically, the bottles 21 adjacent to each other are placed vertically on the conveyor belt 111. Figure 5 and Figure 6 , under the action of the first driving device 112, the conveyor belt 111 runs and conveys the bottle 21 to the right. At this time, under the action of the fourth driving device, the front baffle 124 is located at the left end of the support plate 121 and is ready to receive the bottle 21. The rear baffle 122 is located on the second section 12312, thereby preventing the bottle 21 from interfering with the rear baffle 122 when moving along the support plate 121. The left end of the support plate 121 is close to the right end of the conveyor belt 111, and the upper side of the support plate 121 is basically The fourth driving device is flush with the upper side of the conveyor belt 111 so that the bottle 21 can move from the conveyor belt 111 to the support plate 121. When the bottle 21 moves to the right end of the conveyor belt 111, as the conveyor belt 111 continues to run, the bottle 21 continuously slides from the left end of the support plate 121 to the support plate 121. When the bottle 21 moves to the front baffle 124, the fourth driving device runs and drives the front baffle 124 to move rightward. The front baffle 124 moves rightward synchronously with the bottle 21. Figure 7 When the number of bottles 21 on the support plate 121 reaches a preset value, the extruder 114 moves downward under the action of the second driving device 115 and presses the bottle 21 at the rightmost end of the conveyor belt 111 onto the conveyor belt 111. At the same time, the first driving device 112 stops moving, and the conveyor belt 111 and the bottles 21 on the conveyor belt 111 stop moving to the right. Figure 8 Since the extruder 114 presses the bottle 21 at the rightmost end of the conveyor belt 111, when the bottle 21 stops moving to the right, the bottle 21 at the rightmost end of the conveyor belt 111 will not fall to the right due to inertia. Since the bottles 21 on the conveyor belt 111 are close to each other, the bottles 21 on the conveyor belt 111 will not fall when it stops moving. Then, under the action of the first motor 1132, the rotating shaft 1133 drives the first conveyor belt 1231 to run through the fourth pulley 1235, and the rear blocking bar 122 moves downward along the second section 12312 and stops. The rear baffle 122 moves between adjacent bottles 21 to group the bottles 21. At this time, the rear baffle 122 is located at the lower end of the second section 12312. Then, as the first conveyor belt 1231 continues to run, the first conveyor belt 1231 drives the rear baffle 122 to pass under the third pulley 1234. Then, the rear baffle 122 moves rightward along the first section 12311 and pushes the grouped bottles 21 to continue to move rightward along the support plate 121. In this process, the front baffle 124 moves rightward along with the grouped bottles 21 under the action of the fourth driving device 125. Figure 9When the rear baffle 122 moves to the right end of the first section 12311, the rear baffle 122 and the front baffle 124 both stop moving. The front baffle 124 prevents the grouped bottles 21 from tipping over under the action of inertia when they stop moving. Then the first motor 1132 runs in the reverse direction, and the rear baffle 122 returns to the upper end of the second section 12312 under the action of the first conveyor belt 1231. Then the existing bottle grabbing device takes the grouped bottles 21 off the support plate 121. Then the front baffle 124 moves leftward to the left end of the support plate 121 under the action of the fourth driving device 125. At this point, the application returns to the initial state. Figure 6 , repeat the above steps to proceed to the next round of grouping.

[0026] As an implementation method, limiting protrusions 12341 are circumferentially provided at both ends of the third pulley 1234 to prevent the first conveyor belt 1231 and the third pulley 1234 from being disengaged, and the limiting protrusions 12341 are provided with avoidance grooves 12342 for avoiding the rear barrier rod 122.

[0027] Through the above arrangement, the cooperation between the third pulley 1234 and the first conveyor belt 1231 is more stable. In addition, when the rear block rod 122 passes through the third pulley 1234, the rear block rod 122 is embedded in the avoidance groove 12342, so that the first conveyor belt 1231 runs more smoothly.

[0028] As an implementation method, second side plates 116 are provided on opposite sides of the conveyor belt 111 in the width direction, and support rollers 1161 for supporting the conveyor belt 111 are rotatably connected between the second side plates 116. The first driving device 112 includes a driving wheel 1121 abutting against the conveyor belt 111 and a second motor 1122 connected to the driving wheel 1121.

[0029] Through the above arrangement, the support roller 1161 is used to support the conveyor belt 111 and make the conveyor belt 111 tensioned so that the conveyor belt 111 supports the bottle 21. There is a large friction between the driving wheel 1121 and the conveyor belt 111. When the second motor 1122 drives the driving wheel 1121 to run, the driving wheel 1121 drives the conveyor belt 111 to move.

[0030] As an implementation method, the second drive device 115 includes a screw rod 1151 arranged at both ends of the top plate 113 and a third motor connected to one of the screw rods 1151. The upper end of the screw rod 1151 passes through the top plate 113 and is rotatably connected to the top plate 113. The upper end of the screw rod 1151 is fixedly connected to a synchronous wheel 1153, and the synchronous wheels 1153 are connected by a synchronous belt 1154. The screw rod 1151 extends vertically and is threadedly connected to the end of the extrusion member 114.

[0031] Through the above arrangement, the screw rod 1151 extends vertically. When the third motor drives one of the screw rods 1151 to rotate, the screw rod 1151 drives the other screw rod 1151 to rotate through the synchronous wheel 1153 and the synchronous belt 1154, so that the two screw rods 1151 rotate synchronously. When the screw rod 1151 and the extrusion piece 114 rotate relative to each other, the extrusion piece 114 moves upward or downward along the axial direction of the screw rod 1151.

[0032] As an implementation method, a connecting plate 11311 is fixedly connected to one side of the first side plate 1131 close to the other first side plate 1131, the lower end of the screw rod 1151 is rotatably connected to the connecting plate 11311, and a guide column 11312 extending vertically is fixedly connected between the connecting plate 11311 and the top plate 113, and the guide column 11312 passes through the extrusion piece 114 and is slidably connected to the extrusion piece 114.

[0033] Through the above arrangement, the extrusion piece 114 is more stable when moving, and the connecting plate 11311 can be installed with the screw rod 1151 and the guide column 11312. The guide column 11312 makes the extrusion piece 114 more stable when moving up and down.

[0034] As an implementation method, the fourth driving device 125 includes a second conveyor belt 1251 arranged on opposite sides of the width direction of the support plate 121, and a fourth motor 1252 for driving the second conveyor belt 1251 to operate. The second conveyor belt 1251 extends along the length direction of the support plate 121, and a mounting beam 1253 is arranged between the second conveyor belts 1251. The two ends of the mounting beam 1253 are connected to the corresponding second conveyor belts 1251, and the front baffle 124 is arranged on the mounting beam 1253.

[0035] Through the above arrangement, when the fourth motor 1252 drives the second conveyor belt 1251 to operate, the second conveyor belt 1251 drives the front baffle 124 to move leftward or rightward through the mounting beam 1253 .

[0036] As an implementation method, guide rods 1212 are provided on opposite sides of the support plate 121 in the width direction. The guide rods 1212 extend along the length of the support plate 121. The guide rods 1212 pass through both ends of the mounting beam 1253 and are slidably connected to the mounting beam 1253. With this arrangement, the movement of the mounting beam 1253 and the front baffle 124 is more stable.

[0037] As an implementation method, a guide surface 12111 is provided at one end of the limiting plate 1211 close to the conveyor belt 111 for facilitating guiding the bottle 21 to between the limiting plates 1211 .
