[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] Example 1: See Figure 1-4As shown, a film roll conveying device for plastic cups includes a base 1, a stand 2, a bracket 27, a conveying rod 3, a vertical drive mechanism and a horizontal drive mechanism. The bottom of the base 1 is provided with a supporting caster 4, and the bottom of the stand 2 is vertically installed on the base 1; the conveying rod 3 is slidably connected to the bracket 27 via a connecting piece 5, and the rear end of the bracket 27 is vertically connected to the stand 2; the fixed end of the bottom of the vertical drive mechanism is installed on the base 1, and the output end of the top of the vertical drive mechanism is connected to the bracket 27, and the vertical drive mechanism drives the bracket 27 to move up and down; the horizontal drive mechanism is installed on the bracket 27, and the horizontal drive mechanism is connected to the connecting piece 5, and the horizontal drive mechanism drives the connecting piece 5 to move horizontally along the bracket 27.

[0026] In this embodiment, taking material handling as an example, a film roll is placed on a multi-layer shelf. When retrieving the material, the operator pushes the film roll to the side of the shelf by moving the supporting casters on the ground, with the carrying rod facing the shelf. The operator then drives the bracket and the carrying rod to the same height as the film roll reel through the vertical drive mechanism. The operator then adjusts the carrying rod so that the carrying rod faces the middle of the film roll reel. The operator then drives the connecting member and the carrying rod to move horizontally through the transverse drive mechanism, inserting the carrying rod into the middle of the film roll reel. After the carrying rod is inserted into the film roll, the operator then drives the bracket and the carrying rod upward a certain distance through the vertical drive mechanism, thereby driving the film roll off the shelf support position. The operator then drives the connecting member and the carrying rod back to their original position through the transverse drive mechanism, driving the film roll off the shelf and under the bracket, thus completing the material retrieving operation. After the material is retrieved, the operator then uses the supporting casters to move the carrying device and the film roll on it to the corresponding position for unloading. This method effectively reduces the operator's pulling force and improves the safety of material retrieving and unloading.

[0027] In this embodiment, there are four supporting casters, two of which are arranged on both sides of the front end of the base, and two of which are arranged on both sides of the rear end of the base. Among them, the supporting casters arranged on both sides of the front end of the base are non-steerable, and the supporting casters arranged on both sides of the rear end of the base are steerable supporting casters. This can ensure the convenience of the base during movement on the ground without affecting its normal steering and adjustment of the moving position.

[0028] See also Figure 1 、 2As shown, the vertical drive mechanism includes a manual hydraulic cylinder 6 and a first chain 7. The fixed end of the bottom of the manual hydraulic cylinder 6 is mounted on the base 1. A first sprocket 8 is rotatably mounted on the output end of the top of the manual hydraulic cylinder 6. The first chain 7 is wound around the top outer surface of the first sprocket 8. One end of the first chain 7 is connected to the bracket 27, and the other end is connected to the outer wall of the stand 2, the base 1, or the manual hydraulic cylinder 6. In this embodiment, the other end of the first chain is connected to the outer wall of the manual hydraulic cylinder.

[0029] The vertical drive mechanism utilizes a combination of a manual hydraulic cylinder and a first chain. When the bracket needs to be moved vertically, the manual hydraulic cylinder can be manually operated to drive the bracket's vertical movement. This eliminates the need for batteries, hydraulic pumps, and other limitations, allowing for use in various locations and a wider range of applications. Furthermore, since the manual hydraulic cylinder is fixed in position, only the output shaft at its top can extend and retract. In this embodiment, a first sprocket is rotatably mounted on the output shaft at the top of the manual hydraulic cylinder. The rear end of the first chain is connected to the outer wall of the manual hydraulic cylinder, and the front end of the first chain is connected to the bracket. When the manual hydraulic cylinder output shaft extends, the first sprocket rises. Since one end of the first sprocket is fixed and cannot move up or down, the rise of the first sprocket drives the front end of the first chain upward, thereby driving the bracket upward. Similarly, when the manual hydraulic cylinder output shaft retracts and the first sprocket moves downward, the bracket also descends.

[0030] In the present invention, in order to ensure the safety of the carrying rod of the carrying device when it is moved with a film roll, the vertical drive mechanism will drive the bracket and the film roll to move downward, thereby lowering the overall center of gravity of the carrying device as much as possible to prevent it from tipping over, ensuring safety in use and reducing safety hazards.

[0031] See also Figure 1-3 As shown, a reinforcement frame 9 is further provided on the stand 2, and the middle portion of the outer wall of the manual hydraulic cylinder 6 is connected to the reinforcement frame 9. If only the bottom of the manual hydraulic cylinder is connected to the base, there may be insufficient firmness. Therefore, a reinforcement frame is provided to connect the middle outer wall of the manual hydraulic cylinder to the stand, thereby increasing the firmness of the manual hydraulic cylinder during installation and use. In addition, the reinforcement frame does not contact the output shaft of the manual hydraulic cylinder and will not affect the normal extension and retraction of the output shaft of the manual hydraulic cylinder.

[0032] See also Figure 1-3As shown, a transverse through slot 10 is provided in the middle of the bracket 27. A transverse slide rail 11 is provided on the top of the bracket 27 on the front and rear sides of the transverse through slot 10. The top sides of the connector 5 are connected to the two transverse slide rails 11 respectively. The bottom of the connector 5 passes through the transverse through slot 10 and is arranged below the bottom surface of the bracket 27. The left end of the transport rod 3 is connected to the right side of the bottom of the connector 5, and the transport rod 3 is arranged parallel to the transverse slide rail 11. In the present invention, there is at least one transport rod, or multiple transport rods. If multiple transport rods are used, they are spaced apart from front to back, so that multiple film rolls can be transported simultaneously. In the accompanying drawings, two transport rods are provided, spaced apart from each other.

[0033] In this embodiment, the bracket adopts a hollow frame structure, which can reduce its material consumption and lower costs. At the same time, in order to facilitate the carrying rod to carry the film roll, it is placed below the bottom of the bracket, which can carry film rolls of different heights. (If the carrying rod is placed above the bracket, when the carrying rod moves to the bottom, it may be above the film roll closer to the ground.) At the same time, the transverse slide rail is set at the top of the bracket. The transverse slide rail not only guides the lateral movement of the connecting member, but also supports the connecting member, and is used to bear the weight of the connecting member, the carrying rod and the film roll, and prevent the connecting member from falling off the transverse slide rail.

[0034] See also Figure 1-3 As shown, the transverse drive mechanism includes a left sprocket 12, a right sprocket 13, a second chain 14 and a gripper turntable 15. The left sprocket 12 and the right sprocket 13 are rotatably mounted on the top of the bracket 27 on the left and right sides of the transverse through slot 10, respectively. The axes of the left sprocket 12 and the right sprocket 13 are perpendicular to the extension direction of the transverse slide rail 11. The second chain 14 is wound around the left sprocket 12 and the right sprocket 13. The top of the connecting member 5 is connected to the second chain 14.

[0035] The gripping turntable 15 is connected to the left sprocket 12 . When the gripping turntable 15 rotates, the left sprocket 12 is driven to rotate synchronously.

[0036] Among them, the second chain below the left and right sprockets is connected to the top of the connecting piece. When the connecting piece and the carrying rod need to be moved horizontally, the operator grabs the handle turntable and rotates it, which can drive the left sprocket to rotate. When the left sprocket rotates, it simultaneously drives the second chain to rotate, that is, drives the bottom of the second chain to move left and right, thereby driving the connecting piece to move left and right along the horizontal slide rail. When taking materials, the left sprocket rotates counterclockwise first, driving the connecting piece to move right, causing the carrying rod to move right, and the right end of the carrying rod is outside the right end of the bracket and inserted into the film roll. Then the bracket moves upward, driving the film roll to move upward and out of the material rack, and then drives the left sprocket to rotate clockwise, causing the connecting piece, carrying rod and film roll to move left to the bottom of the bracket, so that the overall counterweight is centered to prevent tipping.

[0037] See also Figure 1-3 As shown, a connecting rod 16 is provided coaxially with the left sprocket 12, the front end of the connecting rod 16 is connected to the rear end of the left sprocket 12, and the rear end of the connecting rod 16 is rotatably connected to the bracket 27;

[0038] The gripping turntable 15 is connected to the connecting rod 16 via a third chain 17 .

[0039] The grabber turntable 15 is rotatably connected to the lower rear end of the bracket 27 via a rotating shaft. A lower sprocket 18 is provided on the rotating shaft, and an upper sprocket 19 is provided at the rear end of the connecting rod 16. The third chain 17 is wound around the upper sprocket 19 and the lower sprocket 18.

[0040] In this embodiment, the gripper disc is lowered to facilitate operator control, especially for film winding and unwinding at relatively high locations. The gripper disc is connected to the left sprocket via a third chain and a connecting rod. Furthermore, the lower and upper sprockets can have different diameters to adjust the speed.

[0041] See also Figure 1-3 As shown, in order to facilitate the operator to push the transport device to move on the ground, a handle 20 is provided on the left and right sides of the rear end surface of the stand. The handle is convenient for the operator to hold and push the transport device to move on the ground.

[0042] See also Figure 3 、 4 As shown, a vertical slide rail 21 is provided on the inner side surfaces of the left and right ends of the stand 2, and the left and right sides of the rear end of the bracket 27 are slidably connected to a vertical slide rail 21 via sliding connectors 26.

[0043] The sliding connection includes a connecting frame 22, two front guide rollers 23 and two rear guide rollers 24 rotatably mounted on the connecting frame 22, the front end of the connecting frame is fixedly connected to the bracket, and the connecting frames of the two groups of the sliding connection are arranged between the two vertical slide rails, the two front guide rollers are arranged at intervals up and down, and the two rear guide rollers are arranged at intervals up and down, each of the front guide rollers is arranged opposite to one of the rear guide rollers, and each of the vertical slide rails is arranged between the two front guide rollers and the two rear guide rollers, the front outer surface of the rear guide roller abuts against the rear side surface of the vertical slide rail, and the rear outer surface of the front guide roller abuts against the front side surface of the vertical slide rail.

[0044] In this embodiment, the connecting frame is located between the two vertical rails, thereby preventing the bracket from moving left or right. The two front guide rollers and the two rear guide rollers act as rolling guides, ensuring smooth vertical movement of the bracket along the vertical frame. Furthermore, support rollers 25 may be provided on the connecting frame, with their axes perpendicular to the axes of the front and rear guide rollers. The outer surfaces of the support rollers abut against the inner surfaces of the corresponding vertical rails, further limiting left or right deviation of the bracket relative to the vertical frame and preventing rigid contact friction between the connecting frame and the vertical rails. Of course, due to the presence of the first chain, support rollers may be omitted.

[0045] Of course, in another embodiment, the vertical drive mechanism can utilize an electric cylinder, with its bottom mounted on the base and its output shaft connected to the bracket. The extension and retraction of the cylinder output shaft drive the bracket's vertical movement. The lateral drive mechanism can utilize a motor and a transverse screw, mounted on the bracket. The ends of the screw are rotatably connected to the bracket, and the middle of the screw is threadedly connected to a connector. The motor drives the screw's rotation, driving the connector and the carrying rod's lateral movement. This approach requires a battery or power cord installed on the stand or base to power the electric cylinder and motor.
