Description

Technical Field

[0001] This utility model relates to the field of soft bag weighing technology, and in particular to a soft bag weighing mechanism and system. Background Technology

[0002] The existing weighing system uses a soft bag weighing system with patent number 202311270267.8. The soft bag is hung on the hanging pin of the weighing system through the bag hanging hole. However, there are problems such as difficulty in putting the soft bag on and off the scale and easy overloading of the scale during the process of hanging the soft bag on the hanging pin of the weighing system. Utility Model Content

[0003] The purpose of this utility model is to provide a soft bag weighing mechanism and system, which solves the problems of existing technology where the soft bag is hung on the bag hanging pin of the weighing system for weighing, and the difficulty of loading and unloading the soft bag and the easy overload of the scale during the process of hanging the soft bag on the bag hanging pin of the weighing system.

[0004] This utility model is implemented as follows: a soft bag weighing mechanism includes a weighing device, the weighing device is provided with an installation structure for placing soft bags, the installation structure includes a first limiting member and a second limiting member, the first limiting member is used to limit the opening end of the soft bag, and the second limiting member is used to hold the body of the soft bag.

[0005] The tube end of the soft bag is locked into the first limiting component for restriction, while the bag body is held in place by the second limiting component. This restricts the entire soft bag in the installation structure, making it a bag-supporting structure, which simplifies weighing. It eliminates the complexity of cooperating with bag hanging pins, and the weighing equipment is not prone to overload due to the force of the bag transfer device.

[0006] A further technical solution of this utility model is: the second limiting member is provided with a vertical limiting groove, the top of the limiting groove is provided with an opening for the side of the soft bag to pass through, and the width of the soft bag away from the tube opening is greater than the width near the tube opening.

[0007] As the soft bag moves along the installation structure, the vertical limiting groove on the second limiting member limits the bag body. The width of the soft bag at the end away from the tube opening is greater than that at the other end, ensuring that the second limiting member limits the side of the soft bag away from the tube opening, so that the soft bag can be unfolded and avoid bending.

[0008] A further technical solution of this utility model is that the opening is wider at the top and narrower at the bottom.

[0009] The opening of the limiting groove is wider at the top and narrower at the bottom, which serves to guide the side of the soft bag.

[0010] A further technical solution of this utility model is: the installation structure is inclined.

[0011] The mounting structure can also be tilted. Under its own weight, the soft bag moves along the mounting structure until the first limiting member limits the opening of the soft bag, and the second limiting member limits the bag body. In conjunction with the tilted mounting structure, the bag body will not bend.

[0012] A further technical solution of this utility model is: the first limiting member is provided with a bending part, and the bending part is provided with a tube opening avoidance part of the soft bag.

[0013] The bending part supports both sides of the tube opening of the soft bag, while the clearance part ensures that the tube opening is not interfered with by the bending part, and that the tube opening of the soft bag can be smoothly inserted into the first limiting member for limiting.

[0014] A further technical solution of this utility model is: the installation structure further includes an installation frame, which is connected to the weighing equipment via a connecting frame for suspending the soft bag on the side of the weighing equipment.

[0015] The soft bag is suspended on the side of the weighing equipment for weighing, which facilitates loading and unloading.

[0016] A further technical solution of this utility model is: the first limiting member is placed at the bottom of the mounting frame, and the second limiting member is placed on both sides of the mounting frame.

[0017] The first limiting component is placed at the bottom of the mounting frame to limit the opening of the soft bag, and the second limiting component is placed on both sides of the mounting frame to limit the sides of the soft bag and thus limit the bag body.

[0018] This utility model also provides a weighing system, including a transfer mechanism, a bag pushing mechanism, a carrier, and the weighing mechanism. The carrier is used to fix the soft bag, and the bag pushing mechanism cooperates with the transfer mechanism to remove the soft bag from the carrier and transfer it to the weighing mechanism.

[0019] The soft bag is first positioned on the carrier. After the carrier moves to the set position on the conveyor line, the bag pushing mechanism pushes the soft bag towards the transfer mechanism. At the same time, the transfer mechanism clamps the soft bag, causing it to detach from the carrier. Then, the transfer mechanism transfers the soft bag detached from the carrier to the weighing mechanism for weighing. After weighing, the soft bag is returned to the carrier to continue being conveyed along the conveyor line.

[0020] A further technical solution of this utility model is: the transfer mechanism includes a gripper, a lifting drive and a translation drive, the output end of the translation drive is connected to the lifting drive, and the output end of the lifting drive is connected to the gripper through the gripper drive.

[0021] The gripper drive is used to drive the gripper to open and close. After the gripper picks up the soft bag, the lifting drive causes the soft bag to detach from the carrier or mounting structure, and then the translation drive causes the soft bag to move horizontally between the mounting structure and the carrier.

[0022] A further technical solution of this utility model is: the bag pushing mechanism includes a servo electric cylinder and a baffle placed at the output end of the servo electric cylinder, the baffle being used to limit the opening end of the soft bag.

[0023] The bag-pushing mechanism is a servo electric cylinder, which prevents the bag-pushing mechanism from interfering with the weighing process.

[0024] The beneficial effects of this utility model are as follows: the tube end of the soft bag is locked into the first limiting member for limitation, while the bag body is held by the second limiting member, so that the entire soft bag is limited in the installation structure, making the soft bag present a bag-supporting type in the installation structure, making weighing simpler; it eliminates the complexity of the cooperation with the bag hanging pin, and the weighing equipment will not be subject to the force of the bag transfer device, which may cause the scale to be easily overloaded.

[0025] The soft bag weighing mechanism adopted in this utility model is a bag-supporting type, which avoids the problems of low success rate, easy overload and damage of the scale by the hanging pin type; the bag pushing mechanism is changed from a cylinder to a servo electric cylinder to avoid interference with the weighing during weighing; the position of the hanging pin on the carrier is adjustable to match the hanging pin hole of the soft bag, and the soft bag liquid inlet gripper is changed from a fixed type to an elastic gripper, optimizing the soft bag loading and unloading tooling.

[0037] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0038] Example 1:

[0039] Figure 1-10 A soft bag weighing mechanism is shown, including a weighing device 1. The weighing device 1 is provided with an installation structure 3 for placing a soft bag 2. The installation structure 3 includes a first limiting member 32 and a second limiting member 33. The first limiting member 32 is used to limit the opening end 21 of the soft bag 2, and the second limiting member 33 is used to hold the bag body of the soft bag 2.

[0040] The tube end of the soft bag is locked into the first limiting component for restriction, while the bag body is held in place by the second limiting component. This restricts the entire soft bag in the installation structure, making it a bag-supporting structure, which simplifies weighing. It eliminates the complexity of cooperating with bag hanging pins, and the weighing equipment is not prone to overload due to the force of the bag transfer device.

[0041] In this embodiment, the second limiting member 33 is provided with a vertical limiting groove 34, and the top of the limiting groove 34 is provided with an opening for the side of the soft bag 2 to pass through. The width of the soft bag 2 away from the tube end 21 is greater than the width near the tube end 21.

[0042] As the soft bag moves along the installation structure, the vertical limiting groove on the second limiting member limits the bag body. The width of the soft bag at the end away from the tube opening is greater than that at the other end, ensuring that the second limiting member limits the side of the soft bag away from the tube opening, so that the soft bag can be unfolded and avoid bending.

[0043] In this embodiment, the opening has a structure that is wider at the top and narrower at the bottom.

[0044] The opening of the limiting groove is wider at the top and narrower at the bottom, which serves to guide the side of the soft bag.

[0045] As other embodiments, such as Figure 6 As shown, the mounting structure 3 is inclined.

[0046] The mounting structure can also be tilted. Under its own weight, the soft bag moves along the mounting structure until the first limiting member limits the opening of the soft bag, and the second limiting member limits the bag body. In conjunction with the tilted mounting structure, the bag body will not bend.

[0047] In another embodiment, the second limiting member 33 is two plate-like structures placed on both sides of the mounting bracket 31.

[0048] In this embodiment, the first limiting member 32 is provided with a bending portion 35, and the bending portion 35 is provided with a clearance portion 36 for the opening 22 of the soft bag 2.

[0049] The bending part supports both sides of the tube opening of the soft bag, while the clearance part ensures that the tube opening is not interfered with by the bending part, and that the tube opening of the soft bag can be smoothly inserted into the first limiting member for limiting.

[0050] In this embodiment, the mounting structure 3 further includes a mounting frame 31, which is connected to the weighing device 1 via a connecting frame 8 for suspending the soft bag 2 on the side of the weighing device 1.

[0051] The soft bag is suspended on the side of the weighing equipment for weighing, which facilitates loading and unloading.

[0052] In this embodiment, the first limiting member 32 is placed at the bottom of the mounting bracket 31, and the second limiting member 33 is placed on both sides of the mounting bracket 31.

[0053] The first limiting component is placed at the bottom of the mounting frame to limit the opening of the soft bag, and the second limiting component is placed on both sides of the mounting frame to limit the sides of the soft bag and thus limit the bag body.

[0054] Example 2:

[0055] A weighing system includes a transfer mechanism 4, a bag pushing mechanism 5, a carrier 6, and a weighing mechanism 7 as described in Embodiment 1. The carrier 6 is used to fix the soft bag 2, and the bag pushing mechanism 5 cooperates with the transfer mechanism 4 to remove the soft bag 2 from the carrier 6 and transfer it to the weighing mechanism 7.

[0056] The soft bag is first positioned on the carrier. After the carrier moves to the set position on the conveyor line, the bag pushing mechanism pushes the soft bag towards the transfer mechanism. At the same time, the transfer mechanism clamps the soft bag, causing it to detach from the carrier. Then, the transfer mechanism transfers the soft bag detached from the carrier to the weighing mechanism for weighing. After weighing, the soft bag is returned to the carrier to continue being conveyed along the conveyor line.

[0057] In this embodiment, the transfer mechanism 4 includes a gripper 41, a lifting drive 42, and a translation drive 43. The output end of the translation drive 43 is connected to the lifting drive 42, and the output end of the lifting drive 42 is connected to the gripper 41 through a gripper drive 44.

[0058] The gripper drive is used to drive the gripper to open and close. After the gripper picks up the soft bag, the lifting drive causes the soft bag to detach from the carrier or mounting structure, and then the translation drive causes the soft bag to move horizontally between the mounting structure and the carrier.

[0059] In this embodiment, the bag pushing mechanism 5 includes a servo cylinder 51 and a baffle 52 placed at the output end of the servo cylinder 51. The baffle 52 is used to limit the opening end 21 of the soft bag 2.

[0060] The bag-pushing mechanism is a servo electric cylinder, which prevents the bag-pushing mechanism from interfering with the weighing process.

[0061] The working principle of this utility model is as follows: The soft bag 2 is fixed on the carrier 6. The transfer mechanism 4 grabs the soft bag 2, moves it horizontally out of the carrier 6, and simultaneously pushes it out by the bag pushing mechanism 5, pushing the tube end 21 of the soft bag 2 out of the carrier 6. The transfer mechanism 4 grabs the soft bag 2 and raises it, moving it horizontally above the mounting structure 3, while the bag pushing mechanism 5 moves synchronously. The transfer mechanism 4 grabs the soft bag 2 and lowers it, placing the soft bag 2 on the mounting structure 3 for weighing. The bag pushing mechanism 5 retracts to avoid contact with the soft bag, preventing interference with the weighing. After weighing is completed, the transfer mechanism 4 grabs the soft bag 2, raises it, then moves it horizontally, lowers it, and moves it horizontally again. The soft bag 2 is returned to the carrier 6, and the bag pushing mechanism 5 moves synchronously, completing the entire weighing process.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
