As shown in fig. 2 and 3, a woven bag 200 holding device 100 includes a support member 5 and a holding tray 1, and the holding tray 1 is attached to a lower side of the support member 5. The suction cup 1 includes a housing 101, and a negative pressure chamber 102 is formed inside the housing 101. The housing 101 has a port 103 at a lower portion thereof, and the port 103 communicates the atmosphere with the negative pressure chamber 102. When the holding device 100 holds the woven bag 200, the port 103 contacts the upper surface of the woven bag 200.
The sucking disc 1 is connected with the supporting piece 5 through a spherical hinge, so that the sucking disc 1 can adjust the orientation of the port part 103 according to the inclination direction of the upper surface of the woven bag 200, and the port part 103 can be tightly attached to the upper surface of the woven bag 200.
The holding device 100 further comprises a support 5 and a telescopic element 2. The telescopic element 2 is preferably a cylinder. The telescopic element 2 comprises a cylinder 201 and a telescopic rod 202, the cylinder 201 is fixedly connected with the support part 5, the telescopic rod 202 is slidably connected with the cylinder 201, and the lower end of the telescopic rod 202 is connected with the holding disc 1 through a spherical hinge connecting structure 3 in a spherical hinge mode. The ball joint connecting structure 3 includes a ball socket portion 301 formed at the lower end of the expansion link 202 and fixedly connected to the expansion link 202, and a ball head portion 302 formed at the upper end of the suction plate 1 and fixedly connected to the suction plate 1. The telescopic rod 202 extends downwards to move the suction disc 1 downwards to be in contact with the upper surface of the woven bag 200, and the telescopic rod 202 applies pressing force which is tightly attached to the upper surface of the woven bag 200 to the suction disc 1. After the suction disc 1 sucks the woven bag 200 by the negative pressure, the telescopic rod 202 retracts, so that the woven bag 200 can be lifted.
The holding device 100 further comprises a negative pressure system 4, the negative pressure system 4 being in communication with the negative pressure chamber 102 of the holding tray 1 for creating a negative pressure within the negative pressure chamber 102. In some embodiments, the negative pressure system 4 includes a negative pressure pump and a connecting tube 401, and the negative pressure pump communicates with the negative pressure chamber 102 through the connecting tube 401.
The holding device 100 further comprises a fixing base 6, a bracket 8 and a motor 9. The support member 5 is rotatably connected to the fixed base 6, the support 8 is fixedly connected to the fixed base 6, and the support 8 is used for connecting the suction device 100 to other equipment, such as a unstacker. In some embodiments, the support 5 is rotatably connected to the fixed seat 6 by a bearing 7. The motor 9 is fixedly connected with the support 5, a driving gear 10 is fixed on an output shaft of the motor 9, an external tooth part 501 is arranged on the outer side of the support 5, and the external tooth part 501 is meshed with the driving gear 10. The output shaft of the motor 9 can rotate the support 5 via the drive gear 10 and the external toothed section 501. After the woven bag 200 is lifted by the suction disc 1, the suction device 100 can drive the woven bag 200 to rotate, and the direction of the woven bag 200 is adjusted.
The holding apparatus 100 may include a plurality of holding trays 1, and a case where the holding apparatus 100 includes two holding trays 1 is shown in fig. 2. The two holding trays 1 hold one woven bag 200 at the same time.
In order to supply negative pressure to the plurality of holding disks 1, the negative pressure system 4 further includes a negative pressure pipe 403, a flow divider 402, and a plurality of connection pipes 401, the negative pressure pump is connected to the negative pressure pipe 403, the negative pressure pipe 403 is connected to the flow divider 402, and the flow divider 402 is connected to each of the plurality of connection pipes 401.

As shown in fig. 3, the two holding trays 1 hold the woven bag 200 from different positions, and thus the woven bag 200 can be stably held. It can be seen that when the upper surface of the woven bag 200 is inclined or has a radian, the port part 103 of the holding tray 1 is adjusted to be adapted to the upper surface of the woven bag 200 by the ball hinge connecting structure 3 between the holding tray 1 and the supporting member 5, so that a reliable sealing connection is formed between the port part 103 of the holding tray 1 and the upper surface of the woven bag 200.
Further, the number of the suction trays 1 is not particularly limited. The number of the holding discs 1 can be two, three, four or five … …, and a plurality of holding discs 1 can hold one woven bag 200 at the same time or can hold a plurality of woven bags 200 at the same time. For example, one holding device 100 includes ten holding trays 1, and each two holding trays 1 are grouped to hold one woven bag 200. Thus, the holding device 100 can hold 5 woven bags 200 at a time.
When a plurality of holding disks 1 are included in the holding device 100, if one of the holding disks 1 is separated from the held woven bag 200, air enters the pipeline through the holding disk 1, and the other holding disks 1 lose negative pressure, so that the woven bag 200 falls down, and an accident is caused.
As shown in fig. 4, in order to solve the above-mentioned problem, the housing 101 is provided with an air intake hole 106, an elastic member 109, and a sealing member 110 capable of sealing the air intake hole 106.

The sealing member 110 is located in the negative pressure chamber 102. Optionally, the sealing member 110 is sheet-like.
The elastic element 109 has one end connected to the sealing member 110 and the other end connected to the housing 101, and the elastic element 109 is used to provide an elastic force for pushing the sealing member 110 away from the suction hole 106. Optionally, the elastic element 109 is a coil spring.
The above structure may be formed in the connection pipe 401, and may also function to close the suction holes 106.
Optionally, the port part 103 is provided with a rubber wrapping layer 104, which can improve the sealing property at the joint of the suction tray 1 and the woven bag 200.
Optionally, the lower end of the suction hole 106 extends toward the inside of the negative pressure chamber 102 to form a protrusion 108, which facilitates the sealing connection with the sealing member 110.
As shown in fig. 5, when the woven bag 200 is detached from a certain suction tray 1, the air suction holes 106 rapidly suck air, and the air flow pushes the sealing member 110 to compress the elastic member 109 to block the air suction holes 106. Therefore, the normal work of the rest sucking discs 1 is not influenced, the woven bag 200 can be prevented from falling, and the use safety of the equipment is improved.
As shown in fig. 6, a baffle 111 is further disposed in the casing 101, an air inlet 112 penetrating the baffle 111 is disposed on the baffle 111, and the position of the air inlet 112 corresponds to the position of the sealing member 110. The air flow formed by the sucked air blows the sealing member 110 to close the suction hole 106. Preferably, the area of the intake vent 112 is smaller than the area of the sealing member 110.
As shown in fig. 7, the holding pan 1 further includes a plurality of guide bars 113 therein, the guide bars 113 being used to provide a guide for the sealing member 110. The guide rod 113 is fixedly connected to the housing 101 of the chuck 1, and the seal member 110 is slidably connected to the guide rod 113.
