Description

Conveying system

Technical Field

The present disclosure relates specifically to a handling system.

Background

In the industries of logistics transportation and the like, objects to be transported are generally transported. When the object to be transported needs to be transported, the object to be transported usually needs to be transported from one place to another, for example, the object to be transported needs to be transported from a container to a transportation vehicle.

At present, the object to be carried is carried by using a manual method. For example, a plurality of workers are respectively located in the container, on the ground and on the transport vehicle, and the object to be transported located in the container is transported to the transport vehicle through a manual transmission mode. However, since the efficiency of transportation by manual operation is low at the present stage, it is difficult to efficiently transport by manual transportation and it is necessary to invest a lot of manpower resources to perform work when a large amount of transportation needs are met. Sometimes, a simple mechanical device can be manually matched to carry the object to be carried, but the simple mechanical device can be fixed at a specific position. For example, a carrier may place an object to be carried in a container on a conveyor from an upstream end of the conveyor and move the object to be carried to a downstream end using the conveyor. However, in general, when performing work, it is necessary to transport an object to be transported in a certain area, and the conveyor cannot move by itself, and it is necessary for a transporting worker to transport the object to be transported from another place to the upstream end of the conveyor.

Accordingly, there is a need to provide a mobile handling system.

The present embodiment relates to a conveying system that can be used for conveying an object to be conveyed. The conveying system may be referred to as a conveyor, a conveying robot, a loader, a loading and unloading robot, a transfer device, an automatic conveying device, or the like. In the conveying system according to the present embodiment, the drive mechanism drives the conveying mechanism to move so that the upstream end of the conveying mechanism is positioned at a predetermined position to receive the object to be conveyed, and conveys the object to be conveyed in the conveying direction to convey the object to be conveyed.

Hereinafter, the carrying system according to the present embodiment will be described in detail with reference to the drawings.

Fig. 1 is an overall schematic view showing a handling system 2 according to an example of the present disclosure. Fig. 2 is a schematic view showing a conveying system 2 according to an example of the present disclosure conveying an object 1 to be conveyed.

It should be noted that, in the following description, relative position and relative direction terms such as "above", "upward", "below", "downward", "up-down", "left", "right", "left", "right", "front", "forward", "rearward", "forward-rearward" and the like in the present specification, reference is made to typical operating gestures and should not be considered limiting.

In the present embodiment, which of the conveyance systems 2 can be used to convey the object 1 to be conveyed (see fig. 1 and 2). That is, the conveying system 2 can convey the object 1 to be conveyed from the predetermined position. In some examples, the handling system 2 may be configured to be mobile.

In some examples, the handling system 2 may be used for handling objects 1 to be handled within a container. When the handling system 2 handles the object 1 to be handled in the container, the handling system 2 is at least partly placed in the container.

In the present embodiment, the object 1 may be a regular-shaped object such as a carton, a steel material, or a wood material. For example, as shown in fig. 2, the object 1 to be carried may be a box-shaped object to be carried. In other examples, the object 1 to be carried may be an irregularly shaped object to be carried.

In the present embodiment, the handling system 2 may include a rack 200 and a handling device 20 (see fig. 1). The rack 200 may be used to support the carrying device 20, and the carrying device 20 may be used to carry the object 1 to be carried.

In some examples, the handling system 2 may further comprise a connecting device 40 (see fig. 1) connecting the handling device 20 and the rack 200.

Hereinafter, for convenience of description, a direction in which the conveying system 2 approaches the object 1 to be conveyed is understood as "toward the front" (a direction indicated by D1 in the embodiment of fig. 1), and accordingly, a direction in which the conveying system 2 moves away from the object 1 to be conveyed is understood as "toward the rear" (a direction indicated by D2 in the embodiment of fig. 1). And with reference to the normal operation posture, the horizontal leftward direction is understood as "toward the left" (the direction indicated by D3 in the embodiment of fig. 1), and correspondingly, the horizontal rightward direction is understood as "toward the right" (the direction indicated by D4 in the embodiment of fig. 1); a vertically upward direction is understood as "toward the upper side" (the direction indicated by D5 in the embodiment of fig. 1), and correspondingly, a vertically downward direction is understood as "toward the lower side" (the direction indicated by D6 in the embodiment of fig. 1). It should be noted that the above relative position and relative direction terms refer to a general operation posture and a general operation manner, and should not be construed as being limiting.

In some examples, the rack 200 may include a load bearing table 201. The carrying device 20 may be provided on the load-bearing table 201. In this case, the load bearing table 201 can serve as a balance weight when the carrying device 20 carries the carton.

In some examples, the load bearing block 201 may be substantially rectangular.

In some examples, the load-bearing platform 201 may have an accommodating space (not shown) therein for accommodating the load-bearing blocks, and the weight of the load-bearing platform may be adjusted by adding or subtracting the load-bearing blocks to the accommodating space. In this case, it is possible to adapt the handling system 2 to handle objects 1 to be handled of different weights.

In some examples, the bottom of the load bearing platform 201 may be provided with rollers (not shown). For example, the rollers may be disposed at the four corners of the bottom of the bearing table 201. In this case, the movement and steering of the load bearing table 201 can be facilitated.

In some examples, the outer peripheral region of the load bearing platform 201 may have a baffle (see fig. 1). In this case, a dust-proof function can be achieved.

In some examples, the handling device 20 may be connected with the load-bearing table 201 through the connection device 40. In some examples, the handling device 20 may be disposed above the load-bearing table 201.

In some examples, the handling device 20 may include a transport mechanism 21 and a drive mechanism 23 (see fig. 2 and 3). The conveying mechanism 21 may be used to convey the object 1 to be conveyed, and the driving mechanism 23 may drive the conveying mechanism 21 to move to a predetermined position. In this case, the conveying mechanism 21 is driven by the driving mechanism 23 to move to a predetermined position, and the object 1 to be conveyed is conveyed via the conveying mechanism 21.

In some examples, the conveying mechanism 21 may have an upstream end 211 near the object 1 to be conveyed and a downstream end 212 far from the object 1 to be conveyed.

In some examples, when the object 1 to be conveyed is conveyed, the object 1 to be conveyed is received from the upstream end 211 of the conveying mechanism 21 and conveyed toward the downstream end 212 of the conveying mechanism in the conveying direction. Here, the direction from the upstream end 211 to the downstream end 212 of the conveying mechanism 21 may be a conveying direction (i.e., a C2 direction in the embodiment shown in fig. 1).

In some examples, for example, in the embodiment shown in fig. 2, the object 1 to be conveyed may be conveyed from the upstream end 211 to the downstream end 212 of the conveying mechanism 21 in the conveying direction.

In some examples, the conveyance direction may be a length direction of the conveyance mechanism 21. In some examples, the transport mechanism 21 may extend along the conveyance direction.

In some examples, the transport mechanism 21 may have a first conveyance face S1. When conveying the object 1, the object 1 may be received from the upstream end 211 of the conveying mechanism 21 and conveyed toward the downstream end 212 of the conveying mechanism 21 via the first conveying surface S1 in the conveying direction.

In some examples, the transport mechanism 21 may include a carriage 35. The carrier 35 may be used to carry the object 1 to be carried. When the object to be conveyed is conveyed, the object 1 to be conveyed can be carried on the carrier 35.

In some examples, the carrier 35 may include first and second oppositely disposed

side panels

351, 352. The first and

second side plates

351 and 352 may be connected by a fixed roller shaft located between the first and

second side plates

351 and 352 and orthogonally connected with the first and

second side plates

351 and 352, respectively. The number of the fixed roller shafts may be one or more.

In some examples, the carrier 35 may further include two fixed rollers respectively disposed at both ends of the carrier 35 and orthogonally connecting the first side plate 351 and the second side plate 352.

In some examples, the carrier 35 may include two pulleys provided at both ends of the carrier 35, and an endless belt wound around the two pulleys (see fig. 2). The conveyor belt may rotate with rotation of one or both pulleys. In this case, when the pulley rotates in the conveying direction, the conveyor can rotate in the conveying direction in accordance with the rotation of the pulley, and the object 1 to be conveyed placed on the conveyor can be conveyed in the conveying direction. That is, the object 1 to be conveyed located upstream of the conveying mechanism 21 may be conveyed to the downstream in the conveying direction by the conveyor belt. In addition, the conveyor belt may form the first conveyance face S1.

In addition, in some examples, the conveyor belt may also rotate in a direction opposite to the conveying direction with the rotation of the pulley. In this case, the object 1 to be conveyed located downstream of the conveying mechanism 21 may be conveyed upstream by the conveyor belt in a direction opposite to the conveying direction.

In some examples, the carrier 35 may also transport the object 1 to be transported by roller conveyance (not shown). Specifically, a plurality of rollers having a predetermined interval may be provided between the first side plate 351 and the second side plate 352, and the plurality of rollers may be rotated. When the plurality of rollers rotate in the conveying direction, the carrier 35 can convey the object 1 to be conveyed placed on the plurality of rollers in the conveying direction. That is, the object 1 to be conveyed located upstream of the conveyance mechanism 21 may be conveyed to the downstream in the conveyance direction by a plurality of rollers using a roller conveyance method. In addition, a plurality of rollers may form the first conveyance surface S1.

Further, in some examples, the plurality of rollers may also rotate in a direction opposite the first conveyance direction. In this case, the object 1 to be conveyed located downstream of the first conveying mechanism 21 may be conveyed upstream in the direction opposite to the first conveying direction by the plurality of rollers.

In some examples, the first side plate 351, the second side plate 352, and the fixed rollers connecting the first side plate 351 and the second side plate 352 may be formed in a frame structure to support the conveyor belt or a plurality of rollers. In other words, a conveyor belt or a plurality of rollers may be disposed between the first side plate 351 and the second side plate 352.

In some examples, the extending direction of the carrier 35 may be the conveying direction.

In some examples, the spacing between the first side plate 351 and the second side plate 352 is adjustable. In this case, for example, when it is necessary to transport a larger volume of the object 1 to be conveyed, the conveying mechanism 21 may be adapted to convey the larger volume of the object 1 to be conveyed by enlarging the interval between the first side plate 351 and the second side plate 352.

In some examples, the transfer mechanism 21 may include a first guide portion 354 and a second guide portion 355 that are oppositely disposed and have a predetermined interval.

In some examples, the first guide portion 354 and the second guide portion 355 may be disposed in parallel above the first conveying surface S1. The object 1 to be conveyed can be placed in a conveying section formed between the first conveying surface S1, the first guide portion 354, and the second guide portion 355 and conveyed. When the object 1 is carried in the carrying section and carried, the first guide portion 354 and the second guide portion 355 can limit and guide the object 1 from sliding off from two sides of the first carrying surface S1, and can facilitate the object 1 to leave the first carrying surface S1 from a predetermined position.

In some examples, the first guide 354 and the second guide 355 may be on both sides of the carrier 35 in a relatively movable manner. For example, when the object 1 to be conveyed with a large width is conveyed, the first guide portion 354 and the second guide portion 355 may move in a relatively distant manner, so that the width of the conveying section is increased to be adapted to the object 1 to be conveyed with a large width.

In some examples, the object 1 to be conveyed may be conveyed along the conveying direction via the first conveying surface S1 along a predetermined route within the conveying section. In some examples, the predetermined route may be a central axis of the first carrying surface S1. When the object 1 to be transported deviates from the predetermined path, for example, when the object 1 to be transported is located in the transportation section and is close to the first guide portion 354 (i.e., the object 1 to be transported deviates from the first guide portion 354), the first guide portion 354 may move to a direction close to the second guide portion 355 by a predetermined distance, so that the object 1 to be transported is located on the axis of the first transportation surface S1 and is transported.

In other examples, when the object 1 to be conveyed with a smaller volume needs to be conveyed, the object 1 to be conveyed can be separated from the first conveying surface S1 from a predetermined position by reducing the distance between the first guide portion 354 and the second guide portion 355.

In some examples, both ends of the first guide portion 354 and the second guide portion 355 are outwardly arc-shaped. In this case, the object 1 to be conveyed can be guided along the end portions of the arc-shaped first guide portion 354 and the second guide portion 355 to the conveyance section between the first guide portion 354 and the second guide portion 355.

In some examples, the handling device 20 may further include an extension handling mechanism, and a telescoping connection (not shown) connecting the extension handling mechanism and the transport mechanism. The extension conveyance mechanism may have a fifth conveyance face.

In some examples, the carriage 35 may be configured to be adjustable in length. Specifically, the carrier 35 may include a support body, a first guide mechanism, a second guide mechanism, a third guide mechanism, a fourth guide mechanism, and a conveyor belt (not shown). Wherein the support body may have a proximal end close to the object 1 to be conveyed and a distal end far from the object 1 to be conveyed, the first guide mechanism may be configured to be movably disposed at the proximal end of the support body, the second guide mechanism may be disposed at the distal end of the support body, the third guide mechanism and the fourth guide mechanism may be disposed between the proximal end and the distal end of the support body and on one side of a plane defined by the first guide mechanism and the second guide mechanism, the object to be conveyed may be conveyed on the other side of the plane defined by the first guide mechanism and the second guide mechanism along a conveying direction from the proximal end to the distal end of the support body (i.e., the second conveying direction), the conveyor belt may be formed into a closed loop sequentially passing through the first guide mechanism, the second guide mechanism and the third guide mechanism, the loop may include a first segment between the first guide mechanism and the second guide mechanism, a second segment between the second guide mechanism and the third guide mechanism and a third segment between the first guide mechanism and the third guide mechanism, the fourth guide mechanism abuts the third segment and is configured to be driven to increase or decrease the length of the linkage mechanism relative to the second segment when the guide mechanism is driven to increase or decrease the length relative to the third segment.

Fig. 3 is a partial schematic view showing the handling system 2 according to the example of the present disclosure. Fig. 4 is a partial sectional view showing the handling system 2 according to the example of the present disclosure. Fig. 3 and 4 show the structures of the connecting device 40 and the driving mechanism 23 by omitting parts thereof that partially shield the connecting device 40 and the driving mechanism 23.

In some examples, the connection device 40 may include a connection substrate 41 provided to the bearing table 201 and configured to be rotatable in the left-right direction, and a first connection mechanism 42 (see fig. 3 and 4).

In some examples, the first connection mechanism 42 may be used to connect the transfer mechanism 21 with the connection substrate 41. In other examples, the first connection mechanism 42 may be used to connect the transport mechanism 21 with the load bearing table 201.

Hereinafter, the first connection mechanism 42 for connecting the transfer mechanism 21 and the connection substrate 41 will be described as an example, and the first connection mechanism 42 for connecting the transfer mechanism 21 and the load-bearing table 201 may be identical to the transfer mechanism 21 for connecting the transfer mechanism 21 and the connection substrate 41.

In some examples, the connection substrate 41 may be connected to the load-bearing table 201 through the rotation member 411. The rotating member 411 may have a circular ring shape (see fig. 3 and 4). For example, the rotating member 411 may be a bearing. The connection substrate 41 can be rotated in the left-right direction (i.e., the direction indicated by D3 or D4 in the embodiment shown in fig. 1) about the rotation member 411.

In some examples, the first connecting mechanism 42 may have a first shaft 421 and a second shaft 422 parallel to the first carrying surface S1 and orthogonal to the carrying direction, and a first connecting portion 423 (see fig. 3 and 4) connected to the first shaft 421 and the second shaft 422 and configured to be rotatable about the first shaft 421 and/or the second shaft 422. The first shaft 421 is provided on the carrier 35, and the second shaft 422 is provided on the connection substrate 41.

In some examples, the first shaft 421 may be disposed at the downstream end 212 of the transfer mechanism 21 (see fig. 3). In other examples, the first shaft 421 may be disposed between the upstream end 211 and the downstream end 212 of the transfer mechanism 21. For example, the first shaft 421 may be disposed between the upstream end portion 211 and the downstream end portion 212 of the transfer mechanism 21 and near the downstream end portion 212.

In some examples, the first connecting mechanism 42 may have a third shaft 424 parallel to the first conveying surface S1 and orthogonal to the conveying direction, and a third connecting portion 425 connected to the third shaft 424 and configured to be rotatable about the third shaft 424 (see fig. 4).

In some examples, the connection device 40 may further include a second connection mechanism 43. Both ends of the second connecting mechanism 43 are fixed to the downstream end portion 212 of the transport mechanism 21 and one side of the bearing table, respectively (see fig. 3 and 4).

In some examples, the second connection mechanism 43 may include a plurality of rollers. The plurality of rollers are connected in a scissor-like fashion such that the second connecting mechanism 43 is of a telescopic and curved configuration (see fig. 3 and 4). In this case, when the carrier 35 is moved by the driving mechanism 23, the end of the second link mechanism 43 connected to the load-bearing table 201 is not moved, and the end of the second link mechanism 43 connected to the carrier 35 moves following the movement of the carrier 35.

In some examples, the second connecting mechanism 43 may have a second carrying face S2 (see fig. 3 and 4). For example, a plurality of rollers may cooperate to form the second conveyance surface S2. The object 1 to be conveyed can be conveyed via the first conveying surface S1 of the carrier 35 and the second conveying surface S2 of the second link mechanism 43.

In some examples, the second carrying face S2 may be inclined downward (see fig. 3 and 4). In this case, the object 1 to be conveyed can naturally slide down by gravity when it is located on the second conveying surface S2.

In some examples, the end of the second connecting mechanism 43 connected to the load-bearing platform 201 may have at least two rollers, which are parallel and horizontally disposed. The two rollers at the end of the second connecting mechanism 43 connected to the load-bearing table 201 can cooperate to form a buffer platform with a third transport surface S3 (see fig. 3 and 4).

In some examples, the third conveying face S3 may be continuous with the second conveying face S2. The object 1 to be conveyed can be conveyed via the second conveying surface S2 and the third conveying surface S3. In this case, the third conveying surface S3 can play a role of buffering to slow down the sliding down speed of the object 1 to be conveyed so as to smoothly leave the third conveying surface S3.

In some examples, the drive mechanism 23 may include a first drive portion 28 (see fig. 3). The first driving portion 28 may be configured to drive the transport mechanism 21 to move in the up-down direction (i.e., the direction indicated by D5 or D6 in the embodiment shown in fig. 1).

In some examples, the first driving part 28 may include a first driving motor 281 and a first driving shaft 282 driven and rotatable by the first driving motor 281. The first drive shaft 282 may be curved (see fig. 3).

In some examples, the first drive shaft 282 may be rotatably connected with the third connector 425 (see fig. 3). The first driving motor 281 drives the first driving shaft 282 to rotate so as to drive the third connecting portion 425 to move in the up-and-down direction, so that the transmission mechanism 21 rotates in the up-and-down direction around the first shaft 421.

In some examples, when the first driving part 28 drives the transfer mechanism 21, the transfer mechanism 21 may rotate in the up-down direction about the first shaft 421.

In some examples, the first driving part 28 may be provided to the connection substrate 41 (see fig. 3). In this case, when the connection substrate 41 rotates in the left-right direction, the first driving part 28 may rotate in the left-right direction along with the connection substrate 41. In this case, when the transport mechanism 21 is rotated in the left-right direction by the connection substrate 41, the first driving unit 28 can drive the transport mechanism 21 to move in the up-down direction without adjusting the angle.

In other examples, the first driving part 28 may be disposed on the load-bearing table 201.

In some examples, the drive mechanism 23 may include a second drive portion 29 (see fig. 3). The second driving portion 29 may be configured to drive the transport mechanism 21 to move in the front-rear direction (i.e., the direction indicated by D1 or D2 in the embodiment shown in fig. 1).

In some examples, the second drive 29 may include a second drive motor 291 and a second drive shaft 292 driven and retractable by the second drive motor 291.

In some examples, the second drive shaft 292 may be rotatably coupled with the first coupling portion 423. In some examples, the second driving motor 291 may drive the second driving shaft 292 to telescopically rotate the first connection portion 423 around the second shaft 422 in the front-rear direction, so that the conveying mechanism 21 can rotate around the second shaft 422 in the front-rear direction. In other words, the second driving portion 29 can drive the transport mechanism 21 to rotate in the front-rear direction about the second shaft 422.

In some examples, the second driving part 29 may be connected with the connection substrate 41. When the connection substrate 41 is rotated in the left-right direction, the second driving part 29 may be rotated in the left-right direction along with the connection substrate 41.

In some examples, the drive mechanism 23 may include a third drive portion 30 (see fig. 4). The third driving part 30 may be configured to drive the conveying mechanism 21 to move in the left-right direction (i.e., the direction indicated by D3 or D4 in the embodiment shown in fig. 1).

In some examples, the third driving part 30 may drive the connection substrate 41 to rotate in the left and right directions. In some examples, the connection substrate 41 may have a transmission gear 412, and the transmission gear 412 may be disposed in an inner space of the rotation member 411 (see fig. 4). In some examples, the drive gear 412 may have a semi-circular shape, or a fully circular shape. Thereby, the rotation of the connection substrate 41 can be facilitated.

In some examples, the third driving part 30 has a third driving motor 301 and a brake gear 302. The brake gear 302 can be engaged with the drive gear 412 (see fig. 4). In this case, when the third driving motor 301 drives the stopper gear 302 to rotate, the transmission gear 412 rotates to rotate the connection substrate 41 in the left-right direction about the rotation member 411 to rotate the transfer mechanism 21 in the left-right direction. In other words, the third driving portion 30 can drive the conveying mechanism 21 to rotate in the left-right direction about the rotating member 411.

In some examples, the upstream end 211 of the conveying mechanism 21 may be positioned at the scheduled object to be conveyed to receive the object to be conveyed 1 by the cooperative driving of the first driving part 28, the second driving part 29 and the third driving part 30.

Fig. 5 is a side view, with hidden, showing a handling system 2 according to an example of the present disclosure. Hereinafter, the different postures of the conveyance system 2 will be described based on the side view of the conveyance system 2 shown in fig. 5. Fig. 5, 6, 7, 8 and 9 show the handling system 2 in different positions with parts of the handling device 20 and the connecting device hidden from view.

Fig. 6 is a schematic view showing the attitude of the handling system 2 according to the example of the present disclosure in an extended and elevated state. In some examples, as shown in fig. 6, when the handling system 2 is in the extended and elevated posture with respect to the embodiment shown in fig. 5, the transfer mechanism 21 may be rotated upward about the first shaft 421 by the first driving unit 28 and forward about the second shaft 422 and the third shaft 424 by the second driving unit 29.

Fig. 7 is a schematic view showing a retracted and elevated attitude of the handling system 2 according to an example of the present disclosure. In some examples, as shown in fig. 7, when the handling system 2 is in the retracted and elevated posture with respect to the embodiment shown in fig. 5, the conveying mechanism 21 may be rotated upward about the first shaft 421 by the first driving part 28 and rotated rearward about the second shaft 422 and the third shaft 424 by the second driving part 29.

Fig. 8 is a schematic view showing a posture in which the handling system 2 according to an example of the present disclosure is retracted and lowered. In some examples, as shown in fig. 8, when the handling system 2 is in the retracted and lowered posture with respect to the embodiment shown in fig. 5, the transfer mechanism 21 may be rotated downward about the first shaft 421 by the first driving part 28 and rotated rearward about the second shaft 422 and the third shaft 424 by the second driving part 29.

Fig. 9 is a schematic view showing an attitude of the handling system 2 according to the example of the present disclosure, which is extended and lowered. In some examples, as shown in fig. 8, when the handling system 2 is in the retracted and lowered posture with respect to the embodiment shown in fig. 5, the transfer mechanism 21 may be rotated downward about the first shaft 421 by the first driving part 28 and rotated forward about the second shaft 422 and the third shaft 424 by the second driving part 29.

In the embodiments shown in fig. 5, 6, 7, 8 and 9, some of the attitudes of the handling system 2 are illustrated, but other attitudes are not described. For example, the transfer mechanism 21 may move forward or backward in the horizontal direction.

Fig. 10 is a plan view showing the handling system 2 according to the example of the present disclosure. Fig. 11 is a schematic attitude view showing the handling system 2 according to the example of the present disclosure turned to the left. Fig. 12 is a schematic view showing an attitude of the handling system 2 according to the example of the present disclosure turned rightward.

Fig. 10, 11 and 12 show the handling system 2 in different positions, with parts of the handling device 20 and the connecting device being hidden.

Hereinafter, the different postures of the conveyance system 2 in the top view will be described with reference to the top view of the conveyance system 2 shown in fig. 10. In the example shown in fig. 11, the conveyance mechanism 21 may be rotated leftward about the rotation member 411 by the driving of the third driving portion 30. In the example shown in fig. 12, the transport mechanism 21 can be rotated rightward about the rotating member 411 by the driving of the third driving portion 30.

In some examples, the handling device 20 may further include a pick-up mechanism 50 (see fig. 1 and 2) connected to the upstream end 212 of the transfer mechanism 21. The pickup mechanism 50 may be used to pick up the object 1 to be conveyed to the upstream end 211 of the conveyance mechanism 21.

In some examples, the pickup mechanism 50 may have a proximal end close to the object 1 to be conveyed, a distal end distant from the object 1 to be conveyed and connected to the upstream end portion 211, and a pickup portion (not shown) for picking up the object 1 to be conveyed. The pickup portion may include an adsorption member (not shown) for adsorbing the object 1 to be conveyed. In this case, the pickup portion may suck the object 1 to be conveyed by the suction member to pick up the object 1 to be conveyed.

In some examples, the suction member may be a vacuum chuck (not shown). The vacuum chuck may include a vacuum control valve, and the vacuum control valve may be configured to draw air between the vacuum chuck and the object 1 to be conveyed when the pickup portion picks up the object 1 to be conveyed to form a negative pressure (not shown) between the vacuum chuck and the object 1 to be conveyed. In this case, when the suction member sucks the object 1 to be conveyed, the suction surface of the vacuum chuck abuts on the surface of the object 1 to be conveyed, and the vacuum control valve sucks air between the suction surface of the vacuum chuck and the surface of the object 1 to be conveyed to form a negative pressure, thereby sucking the suction member to the surface of the object 1 to be conveyed.

In some examples, when the object 1 is conveyed, the pickup portion may move in the direction of the proximal end of the object 1 to be conveyed to pick up the object 1 to be conveyed, and the object 1 to be conveyed may be conveyed from the proximal end of the pickup mechanism 50 toward the distal end to the upstream end 211 of the conveying mechanism 21.

In some examples, the pick-up mechanism 50 may have a fourth carrying face S4 (see fig. 2). In some examples, the object 1 to be conveyed may be conveyed sequentially via the four conveying surfaces S4, the first conveying surface S1, and the second conveying surface S2.

In some examples, the pick-up mechanism 50 may be rotatably coupled with the upstream end 211 of the transport mechanism 21. The pickup mechanism 50 is movable in the up-down direction and/or the left-right direction with respect to the transfer mechanism 21. In this case, the proximal end of the pickup mechanism 50 can be brought close to the object 1 to be conveyed to pick up the object 1 by finely adjusting the position of the pickup mechanism 50, and the direction of the conveying mechanism 21 can be kept unchanged.

While the present disclosure has been described in detail above with reference to the drawings and examples, it should be understood that the above description is not intended to limit the disclosure in any way. Those skilled in the art can make modifications and variations to the present disclosure as needed without departing from the true spirit and scope of the disclosure, which fall within the scope of the disclosure.
