Description

Technical Field

[0001] The utility model relates to the technical field of film roll transportation, in particular to a single-arm shaft device for improving the efficiency of film roll loading and unloading. Background Art

[0002] Companies in the film industry all have the operation of transferring film rolls. The existing operations of transferring film rolls generally have the following methods: 1. Lift the film roll manually (usually by two people) to the designated location; 2. Use a forklift (the forklift includes a main frame, a lifting beam and a supporting frame provided on the lifting beam) to manually lift the film roll onto the supporting frame of the forklift (usually the film roll is placed horizontally), pull it to the designated location, and then manually lift the film roll down; 3. Use a trolley to manually lift the film roll to the trolley table (usually the film roll is placed horizontally), then pull it to the designated location, and then manually lift the film roll down.

[0003] Although the above methods can normally transport (load and unload) the film roll to the designated location, in actual operation, two people are required to work together to carry (lift up and down) the film roll, which is time-consuming and labor-intensive. In addition, for the second and third methods mentioned above, there is a risk of scratching or crushing the film roll during loading and unloading (the bottom of the outer wall of the film roll collides with the forklift or trolley, and is easily scratched when the film roll slides axially).

[0004] To this end, we designed a single-arm shaft device to improve the efficiency of film roll loading and unloading. Utility Model Content

[0030] Embodiment 1, in combination with the attached Figure 1-2 4-5, a single-arm shaft device for improving the efficiency of film roll loading and unloading, comprising a top plate 1, a hanging plate 2 extending downward is provided at the rear end of the top plate 1, a mounting plate 3 spaced and parallel to the hanging plate 2 is provided on the lower plate surface of the top plate 1, the hanging plate 2, the top plate 1 and the mounting plate 3 cooperate to form a hanging portion that can be hung on the lifting beam of a stacker; a single-arm shaft 4 that can be inserted into the center hole of the film roll is vertically fixed to the front plate surface of the mounting plate 3;

[0031] At least two rolling wheels 5 are arranged at intervals along the left and right directions on the top of the hanging part to facilitate adjustment of its left and right positions; the hanging plate 2 is screwed with a locking bolt 6 that vertically penetrates it to facilitate contact with the lifting beam of the forklift and lock the left and right positions of the hanging plate 2.

[0032] During assembly, first remove the support frame of the stacker, then hook the hooking part to the lifting beam of the stacker, and make the single arm shaft 4 face forward. It should be noted that the front and rear mentioned above are defined according to the orientation of the stacker, and the specifics can be referred to in the attached Figure 4 and 5 .

[0033] When in use, the staff first moves the forklift to the vicinity of the film roll to be transported, and then adjusts the height of the forklift's lifting beam through the forklift, and then adjusts the height of the single-arm shaft device so that the single-arm shaft 4 has a moderate height. When the left and right positions of the single-arm shaft device need to be adjusted, the locking state of the single-arm shaft device is released by turning the locking bolt 6, and then the single-arm shaft device is pushed left or right to the appropriate position. At this time, the forklift is pushed forward so that the single-arm shaft 4 is inserted into the center hole of the film roll to complete the operation of loading the film roll, and the above-mentioned action principle can be used when unloading the film roll.

[0034] In this way, the single-arm shaft device can be hung on the lifting beam of the forklift. By operating the forklift and adjusting the left and right positions of the single-arm shaft device, the single-arm shaft 4 can be inserted into the center hole of the film roll to complete the loading and unloading operations of the film roll. Compared with the prior art of completing the loading and unloading operations of the film roll by two people working together to carry it, it not only saves time and effort, but also reduces labor.

[0035] Further, in order to increase the stability of the single-arm shaft 4, a reinforcing plate 7 spaced parallel to the mounting plate 3 is provided at the front end of the top plate 1, and the reinforcing plate 7 is fixedly sleeved on the shaft body of the single-arm shaft 4. According to needs, the reinforcing plate 7 can be only matched and sleeved on the shaft body of the single-arm shaft 4, or can be connected together by welding.

[0036] Furthermore, in order to prevent the mounting plate 3 and the reinforcing plate 7 from being deformed, a connecting block 8 is provided between the lower ends of the mounting plate 3 and the reinforcing plate 7 .

[0037] As required, the single-arm shaft 4 and the mounting plate 3 can be connected by bolts or welding. When welding is used, the rear end surface of the single-arm shaft 4 can be attached to the front surface of the mounting plate 3 and connected by one ring welding. Alternatively, an assembly hole matching the single-arm shaft 4 can be opened on the mounting plate 3, and the connection can be made by two ring weldings at the front and rear ends of the assembly hole.

[0038] Embodiment 2, combined with the attached Figure 1-2 And 4-5, a single-arm shaft device for improving the efficiency of film roll loading and unloading, based on the first embodiment, in order to prevent the mounting plate 3 from affecting the inner space of the hanging part after the single-arm shaft 4 is assembled; the bottom surface of the hanging plate 2 is located above the rear end of the single-arm shaft 4; that is, the lower end of the mounting plate 3 is lower than the lower end of the hanging plate 2, and the single-arm shaft 4 is provided at a position where the mounting plate 3 is lower than the lower end of the hanging plate 2, that is, the height of the connection between the single-arm shaft 4 and the mounting plate 3 is lower than the height of the opening at the lower end of the hanging part, so it will not affect the operation of hanging the single-arm shaft device on the lifting beam of the forklift.

[0039] Embodiment 3, in combination with the attached Figure 1-3 A single-arm shaft device for improving the efficiency of film roll loading and unloading, based on the first or second embodiment, in order to prevent the single-arm shaft 4 from being extended forward during idle time due to the large size of the stacker and being easily scratched by other objects, and affecting the storage of the combination of the single-arm shaft device and the stacker; the single-arm shaft 4 is designed to be a retractable structure.

[0040] Specifically, the single-arm shaft 4 includes a thin shaft 41 whose rear end is fixed to the mounting plate 3, and a thick shaft 42 is axially slidably sleeved on the shaft body of the thin shaft 41, and the front end of the thick shaft 42 extends to the front of the thin shaft 41; a first limiting ring 43 is provided on the shaft body at the front end of the thin shaft 41, and a second limiting ring 44 is provided in the inner cavity of the rear end of the thick shaft 42, so as to prevent the thick shaft 42 from being separated from the thin shaft 41;

[0041] The single-arm shaft 4 further includes a positioning rod 45 whose lower end can penetrate the thick shaft 42 and the thin shaft 41 , so that the thick shaft 42 and the thin shaft 41 are in a shortened state or an extended state.

[0042] It should be noted that an expanded neck is provided at the upper end of the positioning rod 45 so as to facilitate fixing the position of the positioning rod 45 after it is inserted to a certain extent.

[0043] Furthermore, the thin shaft 41 is provided with a positioning hole 411 for the positioning rod 45 to pass through at a position corresponding to the position behind the first limiting ring 43 and the shaft at the rear end of the thin shaft 41; the thick shaft 42 is provided with a positioning countersunk hole 421 which is coaxial with the two positioning holes 411 and for the positioning rod 45 to pass through at a position corresponding to the position in front of the second limiting ring 44; the setting of the countersunk hole can make the expanded neck of the positioning rod 45 sink into the countersunk inner cavity of the positioning countersunk hole 421, thereby preventing the upper end of the positioning rod 45 from being higher than the top of the thick shaft 42, which would affect the operation of inserting the single-arm shaft 4 into the center hole of the film roll.

[0044] Furthermore, a stopper 46 is provided at a position of the thin shaft 41 corresponding to the first limiting ring 43 , so as to facilitate the thick shaft 42 to move to a position where the positioning countersunk hole 421 is coaxial with the front positioning hole 411 .

[0045] With this arrangement, when in use, first pull out the positioning rod 45, pull the thick shaft 42 forward, so that the single-arm shaft 4 reaches the maximum length, and then lock the position of the thick shaft 42 by the positioning rod 45, and then the film roll can be loaded normally. When not in use, first pull out the positioning rod 45, pull the thick shaft 42 backward, so that the single-arm shaft 4 reaches the minimum length, and then lock the position of the thick shaft 42 by the positioning rod 45.

[0046] As required, in order to facilitate pulling the thick shaft 42, a handle structure can be designed at the front end of the thick shaft 42.

[0047] Furthermore, in order to ensure that both ends of the membrane roll can be subjected to force and to prevent the force concentration on the wall of the center hole of the membrane roll and the top edge of the inner end surface of the thick shaft 42, the shaft body at the rear end of the thin shaft 41 is provided with a fixed sleeve 47 with an outer diameter that is the same as the outer diameter of the thick shaft 42; that is, the center hole of the membrane roll is supported by the fixed sleeve 47 and the thick shaft 42 at the same time, which can effectively avoid the concentration of force on the wall of the center hole of the membrane roll.

On the basis of embodiment three, in order to reduce the dynamic friction between the thin shaft 41 and the thick shaft 42, the first limiting ring 43 includes a bearing inner ring 431 fixedly sleeved on the shaft body of the front end of the thin shaft 41, and the outer ring surface of the bearing inner ring 431 is fixedly sleeved with a first bearing retainer 432, and the ball pocket hole of the first bearing retainer 432 is rotatably connected to the first ball 433, and the first ball 433 is rollingly matched with the inner wall of the thick shaft 42; that is, the first limiting ring 43 is a bearing without the outer ring.

[0049] The second limiting ring 44 includes a bearing outer ring 441 fixedly connected to the inner cavity of the rear end of the thick shaft 42, a second bearing holder 442 fixedly connected to the inner ring surface of the bearing outer ring 441, and a second ball 443 rotatably connected to the ball pocket of the second bearing holder 442, and the second ball 443 rolls with the shaft body of the thin shaft 41. In other words, the second limiting ring 44 is a bearing without an inner ring.

[0050] During assembly, firstly, the second limiting ring 44 is movably mounted on the shaft body of the thin shaft 41, and then the stopper 46 or the first limiting ring 43 is installed. After the stopper 46 and the first limiting ring 43 are installed, the rear end of the thick shaft 42 is then mounted on the thin shaft 41, and finally the second limiting ring 44 is installed into the inner cavity at the rear end of the thick shaft 42.
