Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, and in particular to a material bag processing device. Background Art

[0002] In common packaging production lines, material bags need to be neatly stacked in a silo, and then the material bags in the silo are continuously output to the next process. At present, a robot is generally used to extend into the silo from the entrance to push the material bags toward the silo exit. However, when replenishing material bags to the silo, the robot needs to be moved away first, and then the material bags are replenished, and then the robot is moved back to its original position to continue pushing the material bags. This reduces the continuity of the operation and leads to low production efficiency. Summary of the invention

[0003] Based on this, it is necessary to provide a bag handling device to address the problem of low operation continuity and low production efficiency in the traditional bag pushing method.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A bag processing device, comprising:

[0006] Silos for storing bags;

[0007] a silo support, on which the silo is fixedly mounted; and

[0008] The bag pushing mechanism is slidably arranged on the silo bracket, and the side wall of the silo is provided with a slide groove corresponding to the sliding track of the bag pushing mechanism. The bag pushing mechanism has a bag pressing part, which can extend into the silo through the slide groove and can push the bag in the silo to the outlet of the silo as the bag pushing mechanism moves.

[0009] In one of the embodiments, the bag pressing part has a closed state and an open state. The bag pressing part can enter and exit the silo in the closed state and change to the open state inside the silo.

[0010] In one embodiment, the bag pressing part includes two pressing claws arranged opposite to each other, and a closing member is arranged between the two pressing claws, and the closing member is used to provide a closing force to the two pressing claws to move closer to each other, so that the bag pressing part is in a closed state;

[0011] When the two pressing claws enter the interior of the silo, the two pressing claws overcome the closing force under the action of external force and expand relative to each other, so that the bag pressing part is in an open state.

[0012] In one embodiment, the closing member includes a magnet and a ferromagnetic metal, and the magnet and the ferromagnetic metal are respectively arranged at corresponding positions of the two pressing claws to keep the pressing bag portion in a closed state.

[0013] In one embodiment, the bag pushing mechanism comprises:

[0014] A base is slidably arranged on the silo support;

[0015] A first slide bar is slidably disposed on the base, and two pressing claws are movably disposed on the first slide bar, and a moving direction of the two pressing claws relative to the first slide bar is perpendicular to a length direction of the first slide bar; and

[0016] The second slide bar is slidably arranged on the base, and one end of the second slide bar is hinged to the two pressing claws through hinge pieces. When the bag pressing part enters the silo and the first slide bar is stationary relative to the base, the second slide bar can apply external force to the two pressing claws to drive the two pressing claws to expand relative to each other.

[0017] In one embodiment, the bag pushing mechanism further includes a positioning portion, which is disposed between the first slide bar and the base, and is used to keep the first slide bar stationary relative to the base when the first slide bar moves to a preset position relative to the base.

[0018] In one of the embodiments, the bag pushing mechanism further includes a limiting portion, which is disposed at an end of the second sliding rod away from the two pressing claws, and is used to limit a moving range of the second sliding rod relative to the base.

[0019] In one embodiment, the bag pushing mechanism further includes a power source, which is transmission-connected to the second slide bar to drive the bag pressing part to move back and forth.

[0020] In one embodiment, the power source includes a motor, a rack is provided on the second slide bar, and the motor is meshed with the rack through a gear set to drive the second slide bar to move back and forth.

[0021] In one of the embodiments, a linear slide rail is provided on the silo support, and a slide groove cooperating with the linear slide rail is provided on the bag pushing mechanism.

[0022] The above-mentioned bag processing device has at least the following technical effects:

[0023] The material bag handling device of the present invention has a bag pushing mechanism that is slidably disposed on one side of the material bin, and the bag pushing mechanism has a bag pressing portion that can extend into the material bin. When the bag pressing portion extends into the material bin, the material bag can be pushed toward the outlet of the material bin as the bag pushing mechanism moves. When the material bag is used up, the bag pressing portion and the bag pushing mechanism are returned to their positions, and the material bag can be replenished at the same time. During the whole process, the operation of replenishing the material bag does not interfere with the bag pushing mechanism at all, and the replenishment of the material bag and the resetting of the bag pushing mechanism can be performed simultaneously. When the material bag is replenished and the bag pushing mechanism is returned to its position, the material bag pushing operation can be directly continued. Therefore, the material bag handling device of the present invention can improve the continuity of operation and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0044] like Figure 1 and Figure 2 As shown, a bag handling device according to an embodiment of the present invention comprises a silo 100, a silo support 200 and a bag pushing mechanism 300. The silo 100 is fixedly mounted on the silo support 200 for storing bags. The bag pushing mechanism 300 is slidably disposed on the silo support 200, and a chute corresponding to the sliding track of the bag pushing mechanism 300 is disposed on the side wall of the silo 100. The bag pushing mechanism 300 has a bag pressing portion 310, which can extend into the silo 100 through the chute, and can push the bags in the silo 100 toward the outlet of the silo 100 as the bag pushing mechanism 300 moves.

[0045] It can be understood that the silo 100 is fixedly mounted on the silo support 200, which means that when the silo 100 is mounted on the silo support 200, the silo 100 is fixed relative to the silo support 200. The silo 100 can be detachably fixed on the silo support 200 by screws. Alternatively, a fixed frame can also be provided on the silo support 200, and the silo 100 can be fixed in the fixed frame in a pull-out manner. The silo 100 can be a rectangular frame structure, in which the empty part is used for stacking and storing bags. Both ends of the silo 100 are open, so as to serve as an inlet for the bags to enter the silo 100 and an outlet for the bags to be output.

[0046] In the embodiment of the present invention, the bag pushing mechanism 300 is slidably arranged on the silo support 200, and the side wall of the silo 100 is provided with a slide groove corresponding to the sliding track of the bag pushing mechanism 300. It should be noted that the side wall of the silo 100 refers to the circumferential wall surface except the openings at both ends of the silo 100. The bag pushing mechanism 300 has a bag pressing part 310, and the bag pressing part 310 can extend into the silo 100 through the slide groove to push the bag out of the silo 100. When the bag is used up, the bag pressing part 310 and the bag pushing mechanism 300 are returned to their positions, and the bag can be replenished at the same time. During the whole process, the operation of replenishing the bag does not interfere with the bag pushing mechanism 300 at all, and the replenishment of the bag and the resetting of the bag pushing mechanism 300 can be carried out simultaneously. When the bag is replenished, the bag pushing mechanism 300 is also returned to its position, and the bag pushing operation can be directly continued. Therefore, the bag handling device of the present invention can improve the continuity of operation and improve production efficiency.

[0047] The bag pushing mechanism 300 can be slidably arranged on the silo support 200 in various structural forms. In one embodiment, the silo support 200 is provided with a linear slide rail 210, and the bag pushing mechanism 300 is provided with a slide groove 301 that cooperates with the linear slide rail. In other embodiments, the silo support 200 can also be provided with a linear slide groove, and the bag pushing mechanism 300 can be provided with a slider that cooperates with the linear slide groove. In addition, the movement of the bag pushing mechanism 300 can be achieved by using a rodless cylinder or a screw drive.

[0048] The bag pressing part 310 can have various structural forms. Figure 3 and Figure 4 As shown, Figure 3 FIG. 2 shows a schematic structural diagram of the bag pressing part 310 in the bag pushing mechanism 300 in an open state. Figure 4 1 shows a schematic diagram of the structure of the bag pressing part 310 in a closed state. As an practicable manner, the bag pressing part 310 has a closed state and an open state. The bag pressing part 310 can enter and exit the silo 100 in a closed state and change to an open state inside the silo 100. In this embodiment, the bag pressing part 310 has a changeable state. Figure 4 As shown, the volume of the bag pressing part 310 is small when it is in the closed state. When entering and exiting the silo 100 in the closed state, the possibility of interference between the bag pressing part 310 and the silo 100 can be reduced, and the corresponding chute on the side wall of the silo 100 does not need to be too large. Figure 3 As shown, the bag pressing portion 310 is in an open state inside the silo 100, which can ensure that the bag is fully pressed and avoid the phenomenon that the periphery of the bag is warped due to a small pressing surface.

[0049] See also Figure 3As shown, in one embodiment, the bag pressing part 310 includes two pressing claws 311 arranged opposite to each other, and a closing member 312 is arranged between the two pressing claws 311, and the closing member 312 is used to provide a closing force to the two pressing claws 311 to approach each other, so that the bag pressing part 310 is in a closed state. When the two pressing claws 311 enter the interior of the silo 100, the two pressing claws 311 overcome the closing force under the action of an external force and are relatively unfolded, so that the bag pressing part 310 is in an open state. Optionally, the closing member 312 may include a magnet and a ferromagnetic metal, and the magnet and the ferromagnetic metal are respectively arranged at corresponding positions of the two pressing claws 311, so that the bag pressing part 310 is in a closed state. Alternatively, the closing member 312 may also be a tension spring, and the two ends of the tension spring are respectively connected to the corresponding positions of the two pressing claws 311, so that the bag pressing part 310 is in a closed state.

[0050] The structure of the pressure claw 311 can be various, see Figure 3 As shown, the pressing claw 311 may include a pressing block 311a, a buffer frame 311b and a pressure strip 311c, wherein the buffer frame 311b is disposed between the pressing block 311a and the pressure strip 311c. When the pressing claw 311 presses the material bag, the pressure strip 311c directly contacts the material bag, and the pressure strip 311c may be made of a soft material such as rubber. The buffer frame 311b may play a buffering role, and the pressing block 311a is mainly used for connection with other components.

[0051] There are many ways to make the two pressing claws 311 relatively open when the two pressing claws 311 enter the silo 100. Figure 2 and Figure 3 As shown, as an implementable manner, the bag pushing mechanism 300 includes a base 320, a first slide bar 330 and a second slide bar 340. The base 320 is slidably arranged on the silo bracket 200. The first slide bar 330 is slidably arranged on the base 320, and the two pressing claws 311 are movably arranged on the first slide bar 330, and the moving direction of the two pressing claws 311 relative to the first slide bar 330 is perpendicular to the length direction of the first slide bar 330. The second slide bar 340 is slidably arranged on the base 320, and one end of the second slide bar 340 is hinged to the two pressing claws 311 through a hinge. When the bag pressing part 310 enters the silo 100 and the first slide bar 330 is stationary relative to the base 320, the second slide bar 340 can apply an external force to the two pressing claws 311 to drive the two pressing claws 311 to expand relative to each other.

[0052] In this embodiment, before the bag pressing part 310 enters the silo 100, the two pressing claws 311 approach each other under the action of the closing member 312, and the bag pressing part 310 is in a closed state. At this time, the bag pressing part 310 is driven to enter the silo 100 by the first slide bar 330 and the second slide bar 340. When the bag pressing part 310 enters the silo 100 to a certain distance, the first slide bar 330 no longer continues to slide relative to the base 320, while the second slide bar 340 can continue to slide relative to the base 320 toward the silo 100. Under the continuous force of the second slide bar 340, the two pressing claws 311 can be relatively unfolded. In this process, the bag pressing part 310 first enters the silo 100 in a closed state under the action of the first slide bar 330 and the second slide bar 340, and then the bag pressing part 310 is unfolded to an open state in the silo 100 under the action of the second slide bar 340.

[0053] When making the bag pressing part 310 withdraw from the material bin 100, the first slide bar 330 can be kept in a stationary state relative to the base 320, and the second slide bar 340 can be moved in the opposite direction to make the two pressing claws 311 relatively closed. Then, under the continuous power action, the first slide bar 330 and the second slide bar 340 drive the bag pressing part 310 in the closed state to withdraw from the material bin 100.

[0054] There are many ways to slide the first slide bar 330 on the base 320. In one embodiment, a linear slide rail is provided on the first slide bar 330, and a slide groove is provided on the base 320 corresponding to the linear slide rail, and the linear slide rail and the slide groove are slidably matched. In other embodiments, the first slide bar 330 may be provided with a linear slide groove, and a slider is provided on the base 320 corresponding to the linear slide groove, and the linear slide groove and the slider are slidably matched.

[0055] There are many ways to slide the second slide bar 340 on the base 320. In one embodiment, a linear slide rail is provided on the second slide bar 340, and a slide groove is provided on the base 320 corresponding to the linear slide rail, and the linear slide rail and the slide groove are slidably matched. In other embodiments, the second slide bar 340 may be provided with a linear slide groove, and a slider is provided on the base 320 corresponding to the linear slide groove, and the linear slide groove and the slider are slidably matched.

[0056] There are many ways to movably arrange the pressure claw 311 on the first slide bar 330. In one embodiment, one end of the first slide bar 330 is fixedly connected to a slide seat, a linear slide groove is arranged on the slide seat, and a sliding member cooperating with the linear slide groove is arranged on the pressure claw 311.

[0057] See also Figure 3As shown, as an implementable manner, the bag pushing mechanism 300 further includes a power source 370, which is transmission-connected to the second slide bar 340 to drive the bag pressing part 310 to move back and forth. The power source 370 may be a motor. A rack 341 is provided on the second slide bar 340, and the motor is meshed with the rack 341 through a gear set to drive the second slide bar 340 to move back and forth. The second slide bar 340 is driven to move by the power source 370, and then the two pressing claws 311 and the first slide bar 330 are driven to move, thereby achieving a smooth movement of the bag pressing part 310 and improving the stability of the device.

[0058] See also Figure 2 As an implementable manner, the bag pushing mechanism 300 further includes a positioning portion 350, which is disposed between the first slide bar 330 and the base 320. The positioning portion 350 is used to keep the first slide bar 330 stationary relative to the base 320 when the first slide bar 330 moves to a preset position relative to the base 320. By providing the positioning portion 350, the first slide bar 330 can be kept stationary relative to the base 320 at the preset position, so that the bag pressing portion 310 can be smoothly opened after entering the warehouse, and the bag pressing portion 310 can be smoothly closed before leaving the warehouse. Optionally, the positioning portion 350 can be a magnet buckle, and the sub-buckle and the mother buckle of the magnet buckle are respectively disposed at corresponding positions of the first slide bar 330 and the base 320.

[0059] See also Figure 3 As an implementable manner, the bag pushing mechanism 300 further includes a limiting portion 360, which is disposed at one end of the second slide bar 340 away from the two pressing claws 311, and the limiting portion 360 is used to limit the moving range of the second slide bar 340 relative to the base 320. By providing the limiting portion 360, the moving range of the second slide bar 340 relative to the base 320 can be limited so that the second slide bar 340 moves within a preset range. In one embodiment, the limiting portion 360 can be a photoelectric sensor. In an embodiment in which the second slide bar 340 is driven to reciprocate by a motor, the photoelectric sensor can cooperate with the sensor to control the stop of the motor so that the second slide bar 340 moves within a preset range.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
