Description

Technical Field

[0001] The utility model relates to the technical field of production equipment, in particular to a conveying device. Background Art

[0002] Heavy-duty film bags are widely used in liquid packaging. During production, the heavy-duty film bags enter the filling equipment to complete liquid filling and sealing. The filled heavy-duty film bags are placed on the conveying channel of the conveying device and sent to an automatic bag palletizer. The manipulator of the automatic bag palletizer grabs the heavy-duty film bags from the conveying device and puts them into a packing box.

[0003] However, the placement of the heavy-duty film bags when they fall from the filling equipment onto the conveying device is not exactly the same. Some heavy-duty film bags are placed horizontally on the conveying device, some are placed vertically, and some are placed obliquely. When the manipulator grabs the heavy-duty film bags, it is difficult for the manipulator to normally grab the horizontally or obliquely placed heavy-duty film bags. Moreover, the horizontally and vertically disordered heavy-duty film bags cannot be accurately palletized when put into the packing box. More seriously, when the manipulator grabs a horizontally placed heavy-duty film bag, it may crush the heavy-duty film bag and the liquid will flow out, affecting the normal production of the production line and causing pollution. On some production lines, the manipulator is added with an identification function to identify the direction of the heavy-duty film bag, so as to adjust the grabbing direction of the manipulator to grab the heavy-duty film bag and palletize the heavy-duty film bag in a fixed direction. However, this solution greatly increases the workload of the manipulator and reduces the production efficiency.

[0004] Therefore, there is an urgent need for a conveying device to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a conveying device capable of automatically sorting bags.

[0006] To achieve the above purpose, the utility model provides a conveying device, which includes a frame, a transmission mechanism and a first guiding member. The frame is provided with a transportation channel. The transmission mechanism is arranged in the transportation channel and is used to drive the goods to be conveyed to be conveyed from the upstream to the downstream along the transportation channel. The first guiding member is arranged on the frame and close to the first side of the transportation channel. The extending direction of the first guiding member is perpendicular to the plane where the transportation channel is located.

[0007] Optionally, it further includes a second guiding member. The second guiding member is arranged on the frame and close to the second side of the transportation channel. The first guiding member and the second guiding member are arranged in a staggered manner along the upstream and downstream directions of the transportation channel.

[0008] Optionally, the frame includes legs and two groups of parallel steel members arranged on the legs.

[0009] Optionally, both the first guiding member and the second guiding member include a rotating shaft and a roller barrel. The rotating shaft is installed on the frame, and the roller barrel is rotatably installed on the rotating shaft.

[0010] Optionally, both the first guiding member and the second guiding member further include rubber sheets, and the rubber sheets cover the outer wall surface of the roller barrel.

[0011] Optionally, it further includes two guiding side plates, and the two guiding side plates are respectively installed on both sides of the transportation channel and are located downstream of the first guiding member and the second guiding member along the conveying direction of the transportation channel.

[0012] Optionally, the two guiding side plates are arranged in a V shape, and the large opening is located upstream of the conveying direction of the transportation channel.

[0013] Optionally, the transmission mechanism is a roller transmission mechanism. The roller transmission mechanism includes a plurality of rollers and a driving motor group. The plurality of rollers are installed at intervals along the extending direction of the transportation channel, and the driving motor group is in transmission connection with the rollers to drive the rollers to rotate.

[0014] Optionally, the transmission mechanism is a belt transmission mechanism. The belt transmission mechanism includes a belt, a driving motor, and two tensioning wheels. The two tensioning wheels are rotatably installed at intervals at the upstream and downstream of the transportation channel. The belt is arranged on the tensioning wheels and is tensioned. The driving motor is connected to one of the tensioning wheels to drive the belt to move.

[0015] Optionally, the transmission mechanism is a crawler transmission mechanism. The crawler transmission mechanism includes a plurality of gears, a crawler, and a driving motor. The plurality of gears are rotatably installed on the transportation channel. The crawler is arranged on the gears and is tensioned. The driving motor is in transmission connection with one of the plurality of gears.

[0016] As can be seen from the above, in the technical solution provided by the present invention, when the heavy-duty film bag moves from the upstream to the downstream along the conveying channel, when the inclined and horizontally placed heavy-duty film bag touches the first guiding member close to the first side of the conveying channel, part of the heavy-duty film bag is blocked by the first guiding member. Under the action of friction and the like, the heavy-duty film bag rotates around the first guiding member. When the heavy-duty film bag rotates to the vertical direction, the heavy-duty film bag is no longer blocked by the first guiding member and continues to move downstream of the conveying channel, realizing the function of automatically arranging the bags.

[0035] Embodiment 1

[0036] Embodiment 1 provides a conveying device, as Figures 1 to 4 shown. The conveying device of this embodiment includes a frame 100, a first guiding member 210 and a transmission mechanism. The frame 100 is provided with a transportation channel 110 extending in the first direction. Specifically, the frame 100 is preferably made of steel. The frame 100 has legs 101 and two groups of parallel steel members 102 provided on the legs 101. The two groups of parallel steel members 102 form a conveying platform, and the extending space between the two steel members forms the transportation channel 110. A transmission mechanism is provided in the transportation channel 110. The transmission mechanism is used to drive the goods to be conveyed along the transmission channel 110 from the upstream 111 to the downstream 112. The first guiding member 210 is provided on the frame 100 and close to the first side 113 of the transportation channel 110. The extending direction of the first guiding member 210 is perpendicular to the plane where the transportation channel 110 is located. The first guiding member 210 is used to automatically sort out the goods moving in the transportation channel 100. The first guiding member 210 is provided on the steel members 102 on both sides of the transportation channel 110, and is close to the middle position between the upstream 111 and the downstream 112 of the transportation channel 110, preferably at the middle position between the upstream 111 and the downstream 112. The first guiding member 210 may be a columnar part, a rotating shaft or a rotating wheel. The contact surface of the first guiding member 210 with the heavy-duty film bag 1 preferably adopts an arc surface.

[0037] Refer to Figures 5a to 5bAs shown in the figure, in this embodiment, the goods to be conveyed are heavy-duty film bags 1. When the heavy-duty film bags 1 move along the conveying channel 110 from the upstream 111 to the downstream 112, when the inclined and lateral (perpendicular to the extending direction of the conveying channel 110) heavy-duty film bags 1 encounter the first guiding member 210 near the first side of the conveying channel 110, part of the heavy-duty film bags 1 are blocked by the first guiding member 210. Under the action of friction and the like, the heavy-duty film bags 1 rotate around the first guiding member 210. When the heavy-duty film bags 1 rotate to the vertical direction (approximately consistent with the extending direction of the conveying channel 110) or close to the vertical direction, the heavy-duty film bags 1 are no longer blocked by the first guiding member 210, and the heavy-duty film bags 1 continue to move downstream of the conveying channel 110, realizing the automatic bag arranging function. The manipulator located downstream of the conveying channel 110 can accurately grasp the heavy-duty film bags 1, and the heavy-duty film bags 1 cannot be accurately stacked when placed in the packing box. Since the utility model realizes automatic bag arranging during the transmission process, it reduces the recognition time and adjustment time of the manipulator, simplifies the operation procedure of the manipulator, and improves the working efficiency of packaging.

[0038] The conveying device of Embodiment 1 is a belt-type conveying device. Referring to Figure 2 and 3 as shown, the transmission mechanism is a belt transmission mechanism 310. The belt transmission mechanism 310 includes a belt 311, a driving motor 312, and two tension wheels 313. The two tension wheels 313 are rotatably installed at intervals at the upstream 111 and downstream 112 of the transportation channel 110, and the two tension wheels 313 are installed between two steel members 101. The belt 311 is arranged on the tension wheels 313 and is tensioned. The driving motor 312 is connected to one of the two tension wheels 313 for driving the belt 311 to move. When the goods to be conveyed are placed on the belt 311, the driving motor 312 is started to drive the tension wheels 313 to rotate, driving the belt 311 to move, so that the goods to be conveyed are conveyed from the upstream 111 to the downstream 112 along the conveying channel 110.

[0039] Referring to Figure 3 as shown, the belt transmission mechanism 310 further includes a supporting wheel 314. The supporting wheel is arranged between the two tension wheels 313 for supporting.

[0040] Preferably, referring to Figures 1 to 3 as shown, the conveying device includes a second guiding member 220. The second guiding member 220 is arranged on the frame 100 and near the second side 114 of the transportation channel 110. The guiding surface of the second guiding member 220 faces the transportation channel 110. The first guiding member 210 and the second guiding member 220 are arranged staggeredly along the upstream and downstream directions of the conveying channel 110, as Figure 1 and 2As shown, the second guiding member 220 of this embodiment is provided at the upstream position of the first guiding member 210. Since the position of the heavy-duty film bag 1 on the conveying channel 110 of the conveying device may deviate towards the first side or the second side, the second guiding member 220 is provided to automatically comb the heavy-duty film bag 1 that deviates towards the second side. The first guiding member 210 may be a columnar portion, a rotating shaft or a rotating wheel. The contact surface of the second guiding member 220 with the heavy-duty film bag 1 preferably adopts an arc surface. In this embodiment, the second guiding member 220 is located at the upstream position of the first guiding member 210.

[0041] In this embodiment, referring to Figure 2 and 3 As shown, both the first guiding member 210 and the second guiding member 220 include a rotating shaft 201 and a cylinder 202. The rotating shaft 201 is installed on the frame 100. One end of the rotating shaft 201 is fixedly installed on the steel bar 102. The rotating shaft 201 is perpendicular to the plane where the transportation plane 110 is located. As Figure 4 shown, the cylinder 202 is rotatably installed on the rotating shaft 202. The rotating cylinder 202 has a central rotating hole, and the central rotating hole is rotatably sleeved on the outer wall surface of the rotating shaft 201. Since the rotating cylinder 202 can rotate, when the heavy-duty film bag 1 contacts the outer surface of the rotating cylinder 202, a static friction force is formed between the rotating cylinder 202 and the heavy-duty film bag 1. When the heavy-duty film bag 1 turns, the rotating cylinder 202 also rotates around the rotating shaft 201. At this time, the heavy-duty film bag 1 can achieve a better turn. The outer wall surface of the cylinder 202 is a cylindrical surface for contacting the heavy-duty film bag 1. When the heavy-duty film bag 1 contacts the first guiding member 210 or the second guiding member 220, since the heavy-duty film bag 1 has a certain fluidity, setting the cylinder 202 can prevent the heavy-duty film bag 1 from being stuck by the guiding member and avoid the heavy-duty film bag 1 being stuck at the first guiding member 210 or the second guiding member 220.

[0042] As a preference, the diameter of the cylinder 202 can be set according to the length and width of the heavy-duty film bag 1 of the goods to be conveyed to be automatically combed, and it is preferably set according to the ratio of the length of the heavy-duty film bag: the diameter of the cylinder = 6 - 8:1.

[0043] In this embodiment, both the first guiding member and the second guiding member further include a rubber sheet 203, and the rubber sheet 203 is made of rubber material. The rubber sheet 203 is coated on the outer wall surface of the cylinder 202. Setting the rubber sheet 203 serves a buffering function to reduce the impact between the heavy-duty film bag 1 and the guiding member, and the rubber sheet 203 has good friction performance and can better guide the heavy-duty film bag 1 to turn. Especially, a sanding texture structure is provided on the surface of the rubber sheet 203 to increase the friction force.

[0044] As a preference, referring to Figure 2As shown, the conveying device includes two guide side plates 230, which are respectively installed on both sides of the transport channel 110 and are located downstream of the first guide member 210 and the second guide member 220 along the conveying direction of the transport channel 110. In particular, the two guide side plates 230 are arranged in an "eight" shape, with the large opening located upstream of the transport channel 110 in the conveying direction.

[0045] Reference Figures 6a to 6c As shown, in this embodiment, the cargo to be conveyed is a heavy-loaded film bag 1. When the heavy-loaded film bag 1 moves along the conveying channel 110 from the upstream 111 to the downstream 112, when the horizontal (perpendicular to the extending direction of the conveying channel 110) heavy-loaded film bag 1 hits the second guide member 220, it is blocked by the second guide member 210, causing the heavy-loaded film bag 1 to rotate around the second guide member 220. Referring to Figure 6b, when the heavy-loaded film bag 1 leaves the second guide member 220, it has not yet rotated to the vertical direction (approximately consistent with the extending direction of the conveying channel 110). At this time, the heavy-loaded film bag 1 continues to move downstream and is guided to the middle of the guide belt 311 by the side plate 230. The heavy-loaded film bag 1 is completely oriented in the vertical direction, allowing the robot located downstream of the conveying device to accurately grasp the heavy-loaded film bag 1.

The conveying device of this embodiment is a roller conveying device, comprising a frame 100, a first guide member 210, a second guide member 220, and a transmission mechanism. The arrangement of the frame 100, first guide member 210, and second guide member 220 in this embodiment is the same as that of Example 1 and will not be further described here.

[0048] The conveying mechanism in this embodiment is a roller conveyor mechanism 320. Each roller conveyor mechanism 320 includes a drive motor assembly 322 and multiple rollers 321. The rollers 321 are spaced apart along the extension of the transport channel 110. The drive motor assembly 322 is in driving connection with the rollers 321 to drive the rollers 321. Typically, three rollers 321 are driven by one drive motor. The drive motor assembly 322 includes multiple drive motors, with each three rollers 321 being in driving connection with one drive motor. During operation, the rollers 321 rotate, driving the heavy-loaded film bags 1 to be transported from upstream to downstream.
