Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to the field of bag-supporting technology, specifically referring to a trolley for supporting ton bags. Background Technology

[0002] Stacking refers to the act or process of neatly stacking items, and is widely used in logistics, warehousing and other fields.

[0003] Palletizing refers to the act of neatly stacking items (such as bags of rice, boxes of goods, etc.) manually or mechanically. Manual palletizing is common in traditional warehousing scenarios. Mechanical assistance includes forklift palletizing (different methods such as crimping and overlapping) or automated palletizing machines (which achieve standardized stacking through identification, gripping, and handling).

[0004] With the advancement of technology, palletizing robots are frequently used for palletizing. There are many types of palletizing, such as bag palletizing, box palletizing, and bulk palletizing. When palletizing bulk materials, a bag-opening device is needed to open the bag opening and then load the bulk materials into the bag. As the material is continuously loaded, the bag opening needs to be moved upwards periodically to provide sufficient space for the bulk materials. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a bag-opening trolley that opens the bag opening while simultaneously moving the bag opening upwards during the filling process, thus meeting production needs.

[0006] This utility model relates to a trolley for supporting ton bags, which is achieved through the following technical solution. It includes a support frame that opens the bag opening from the outside of the bag, a vehicle body located directly below the support frame, and two support frames that connect the vehicle body and the support frame and are arranged opposite to each other. Each support frame includes a first support rod and a second support rod that are staggered and hinged at the intersection. The bottom end of the first support rod is hinged to a first base, and the top end is hinged to the support frame. The bottom end of the second support rod is hinged to the vehicle body, and the top end is hinged to the second base. The first base slides on the vehicle body, and the second base slides on the support frame. The vehicle body is also equipped with a first driving device that drives the first base to slide.

[0007] In use, the bag is placed into the support frame and supported by the vehicle body. The support frame then opens the bag opening from the outside. The palletizing robot grabs the loose material and puts it into the bag. Then, the first drive device drives the first base to slide, so that the distance between the bottom of the first support rod and the second support rod gradually decreases, and the distance between the top also gradually decreases. At this time, the support frame drives the support frame to move upward, which in turn drives the bag opening to move upward, thus realizing the upward movement of the bag opening during the filling process and meeting production needs.

[0008] Preferably, the first driving device includes a first motor, a ball screw connected to the output shaft of the first motor and extending along the sliding direction of the first base, a ball nut connected to the ball screw via balls and a reversing device, a connecting rod connected to the ball nut via a connecting plate, the two ends of the connecting rod being connected to two first bases respectively, and a first slide rail slidably connected to the first base on the vehicle body.

[0009] In this preferred embodiment, the ball screw is connected to a ball nut via balls and a reversing device. The ball nut is bolted to the connecting rod via a connecting plate. The rotation of the first motor drives the ball screw to rotate, which in turn drives the connecting rod to move longitudinally via the ball nut and the connecting plate, thereby causing the two first bases to slide synchronously longitudinally.

[0010] Preferably, the first support rod has an elongated hole through which the second support rod passes. This preferred embodiment facilitates adjustment of the hinge position of the first and second support rods by providing the elongated hole.

[0011] Preferably, the vehicle body is equipped with a support platform for supporting the ton bags. This preferred embodiment uses the support platform to support and position the ton bags.

[0012] Preferably, the support frame includes a rectangular frame with four supports extending inward along the diagonal of the rectangle and located at the four corners of the rectangle. The supports are provided with hooks for hooking the bag.

[0013] In use, this preferred solution provides support to the hooks through the setting of the support, and the setting of four hooks makes it easy to hook the pull rope of the ton bag from four directions.

[0014] Preferably, two adjacent supports are provided with cylinders extending along the diagonal of the rectangle, and hooks on these two supports are connected to the extended ends of the corresponding cylinders.

[0015] In use, the two cylinders extend, which in turn extends the hook, making it easy to hang the drawstring of the ton bag on the hook. Then the cylinders retract, and the drawstring opens the opening of the ton bag, thus opening the bag mouth to facilitate the loading of materials.

[0016] Preferably, the frame includes two crossbeams and two longitudinal beams located between and connecting the two crossbeams. The transverse length between the two longitudinal beams is less than the length of the crossbeams. The support is slidably mounted in a square tube along the diagonal of a rectangle. The square tube is fixed to the crossbeams and longitudinal beams. A pin is connected to the square tube and inserted into the crossbeam or longitudinal beam. The support has a positioning hole through which the pin passes.

[0017] In this preferred embodiment, the pin passes through the square tube and the positioning hole inside the square tube, and then connects to the longitudinal or transverse beam, thereby positioning the support inside the square tube. Since the sizes of the ton bags vary, when the hook position needs to be adjusted, the position of the support inside the square tube is adjusted, thus changing the position of the positioning hole. When the positioning hole is located at the top of the transverse / longitudinal beam, the pin passes through the square tube and the positioning hole and is inserted into the transverse / longitudinal beam, thereby fixing the square tube and support on the transverse / longitudinal beam, thus allowing the hook position to move and further accommodating the opening of ton bags of different sizes. The transverse length between the two longitudinal beams is less than the length of the transverse beam, making it easier for the square tube to be fixed to the transverse and longitudinal beams.

[0018] Preferably, the vehicle body is connected to two longitudinally arranged and laterally extended shafts, each shaft is equipped with a roller, and a longitudinally extended track is provided below the roller. The vehicle body is also equipped with a second motor that drives one of the shafts to rotate.

[0019] In use, this preferred solution guides the movement of the vehicle body through the setting of the track, and facilitates the movement of the vehicle body through the setting of the second motor.

[0020] Preferably, the track is provided with two limiting plates arranged longitudinally to restrict the movement of the vehicle body. The two limiting plates are located at the foremost and rearmost ends of the vehicle body, respectively, with the vehicle body positioned between the two limiting plates. In this preferred embodiment, the two limiting plates are located at the foremost and rearmost ends, serving as the final limit to prevent the vehicle body from moving forward or backward.

[0021] Preferably, a pallet for supporting ton bags is bolted to the support platform, and the pallet has a forklift slot for forklift handling.

[0022] Since the supporting area of ​​the pallet is larger than that of the support platform, this preferred solution is suitable for supporting ton bags with large bottom areas using pallets, while for ton bags with relatively small bottom areas, pallets can be omitted and the support platform can be used directly for support. The support platform serves to support the ton bags and fix the pallet. The pallet is equipped with forklift slots for easy forklift handling.

[0023] The beneficial effects of this utility model are as follows: The bag is placed into the support frame and supported by the vehicle body. Then, the support frame opens the bag opening from the outside of the bag. The palletizing robot grabs the loose material and puts it into the bag. Then, the first drive device drives the first base to slide, so that the distance between the bottom of the first support rod and the second support rod gradually decreases, and the distance between the top also gradually decreases. At this time, the support frame drives the support frame to move upward, thereby moving the support frame upward and driving the bag opening upward, thus realizing the process of loading material and moving the bag opening upward to meet production needs. The rotation of the first motor drives the ball screw to rotate, thereby driving the connecting rod to move longitudinally through the ball nut and the connecting plate, thereby driving the two first bases to slide synchronously longitudinally.

[0032] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0033] See attached document Figure 1-5This utility model discloses a trolley for supporting ton bags, comprising a longitudinally movable body 1. Two longitudinally arranged and laterally extended rotating shafts 13 are connected to the upper shaft of the body 1. Rollers are provided on the rotating shafts 13, and a longitudinally extended track 6 is provided below the rollers. Two limiting plates 7 are arranged longitudinally on the track 6 and restrict the movement of the body 1. The two limiting plates are located at the foremost and rearmost ends of the body's movement, respectively. The body 1 is located between the two limiting plates 7. When the trolley moves forward, the foremost limiting plate 7 restricts the body 1 from continuing to move forward. When the trolley moves backward, the rearmost limiting plate 7 restricts the body 1 from continuing to move backward. The setting of the two limiting plates achieves hard limiting of the forward and backward movement of the trolley.

[0034] The vehicle body 1 is equipped with a second motor 14. The output shaft of the second motor 14 is equipped with a sprocket, and a rotating shaft 13 is also equipped with a sprocket. The two sprockets are connected by a chain, that is, the vehicle body 1 is also equipped with a second motor 14 that drives a rotating shaft 13 to rotate.

[0035] A support frame 2 is provided on the upper part of the vehicle body 1 to open the bag opening from the outside of the bag body. The support frame 2 includes a rectangular frame. The frame is provided with four supports 11 extending inward along the diagonal of the rectangle and located at the four corners of the rectangle. The supports 11 are provided with hooks 10 for hooking the bag body.

[0036] Two adjacent supports 11 are provided with cylinders 9 extending along the diagonal of the rectangle, and hooks 10 on these two supports 11 are connected to the extended ends of the corresponding cylinders 9.

[0037] The frame includes two crossbeams and two longitudinal beams located between and connecting the two crossbeams. The crossbeams extend laterally, and the longitudinal beams extend longitudinally. The lateral length between the two longitudinal beams is less than the length of the crossbeams. The support 11 slides along the diagonal of the rectangle inside the square tube 12. The square tube 12 is welded to the crossbeams and longitudinal beams. The square tube has a first through hole located directly above the crossbeam and a second through hole located directly above the longitudinal beam. Both the first and second through holes are equipped with pins. The square tube is welded to the crossbeams and longitudinal beams.

[0038] The support has a positioning hole for the pin to pass through. After the pin 18 passes through the second through hole or the first through hole and the positioning hole in the square tube, it is connected to the longitudinal beam or the transverse beam, thereby realizing the positioning of the support in the square tube.

[0039] When the positioning hole and the first through hole are set coaxially, the pin passes through the positioning hole and the first through hole and is inserted into the crossbeam to fix the support inside the square tube.

[0040] When the positioning hole and the second through hole are set coaxially, the pin passes through the positioning hole and the second through hole and is inserted into the longitudinal beam to fix the support inside the square tube.

[0041] Two longitudinally arranged support frames 3 are also provided between the frame and the vehicle body 1. The support frame 3 includes a first support rod 16 and a second support rod that are staggered and hinged at the intersection. That is, the first support rod 16 and the second support rod are arranged in an X shape. The first support rod 16 has an elongated hole for the second support rod to pass through. At the intersection of the first support rod 16 and the second support rod, there is a hinge shaft that is axially connected to both the first support rod 16 and the second support rod. The hinge shaft extends laterally.

[0042] The bottom end of the first support rod 16 is hinged to the first base, and the top end is hinged to the longitudinal beam of the support frame 2. The bottom end of the second support rod is hinged to the vehicle body 1, and the top end is hinged to the second base. The vehicle body 1 is provided with a first slide rail 4 that extends longitudinally and is slidably connected to the first base. The bottom surface of the longitudinal beam is provided with a second slide rail 17 that is slidably connected to the second base. The vehicle body 1 is also provided with a first driving device that drives the first base to slide. The first base is slidably connected to the vehicle body 1. The first slide rail 4 and the second slide rail 17 are located on the same side of the hinge axis.

[0043] The vehicle body 1 is also provided with a first driving device that drives the first base to slide. The first driving device includes a first motor 15, a ball screw connected to the output shaft of the first motor 15 and extending along the sliding direction of the first base, a ball nut connected to the ball screw through a ball and a reverser, a connecting plate fixed to the ball nut, the connecting plate being bolted to the connecting rod 5, and the two ends of the connecting rod 5 being connected to the two first bases respectively.

[0044] The vehicle body 1 is equipped with a support platform located between two support frames 3, which supports ton bags. A pallet 8 for supporting ton bag segments is bolted to the support platform. The pallet 8 has a forklift slot for forklift handling. When using ton bag segments, if the bottom area of ​​the ton bag segments is large, the pallet increases the support area with the ton bag segments, thereby increasing the support area of ​​the ton bag segments. piece For stable support, when using ton bags, if the bottom area of ​​the ton bag is small and the support platform is sufficient to support the ton bag, a pallet is not required, and the support platform can be used to support the ton bag alone.

[0045] In use, the ton bag is placed into the support frame 2 and supported by the support platform. The four pull ropes of the ton bag are then hung on the four hooks. At this time, the contraction of the cylinder 9 causes the four hooks 10 to open the bag opening. The palletizing robot grabs the loose material and puts it into the bag. Then, the rotation of the first motor 15 drives the ball screw to rotate, which in turn drives the connecting rod 5 to move longitudinally through the ball nut and the connecting plate. This causes the two first bases to slide synchronously longitudinally, so that the distance between the bottom of the first support rod 16 and the second support rod gradually decreases, and the distance between the tops also gradually decreases. At this time, the support frame 3 drives the support frame 2 to move upward, which in turn drives the bag opening upward, thus realizing the upward movement of the bag opening during the filling process to meet production needs. After the palletizing is completed, the rotation of the second motor 14 drives the vehicle body 1 to move longitudinally forward to the unloading point for unloading.

[0046] When using ton bags, the pallet is bolted to the support platform, and the palletizing robot puts the material into the ton bag.
