Abstract

This utility model discloses a mobile steel strip packaging station for elevator guide rail bundling and packaging, comprising several packaging units and an air tank mounted on a handcart. Each packaging unit is supported by a pair of low-position rollers, a pair of mid-position arc-shaped springs, and a pair of high-position rollers, which abut against the circumferential surface of the steel strip roll, thus collectively supporting the steel strip roll within the placement space, allowing the steel strip roll to roll within this space. The low-position rollers are mounted on a low-position support, and the high-position rollers are mounted on a high-position support. A length-measuring stand is located at the top of the high-position support, on which length-measuring rollers are mounted; a scale is located on the side of the high-position support; and a cutter is located beside the high-position support to cut the steel strip to the measured length. The air tank is connected to existing pneumatic tensioning pliers and locking pliers via an air pipe. This steel strip packaging station integrates all aspects of elevator guide rail packaging into a handcart-type packaging station, avoiding material waste, saving production space, and promoting efficient production.

Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail production technology, and in particular to a mobile steel strapping station for bundling and packaging elevator guide rails. Background Technology

[0002] The applicant is a large elevator parts manufacturer. Currently, in the elevator guide rail packaging process, the company needs to use steel strips to bundle and package the finished guide rails. In the past, the packaging process involved placing rolls of steel strips on the ground. Workers would estimate the approximate cross-sectional circumference of a bundle of elevator guide rails based on the number of rails specified in the customer order, thus determining the required length of steel strip to be cut. A certain allowance was left in the cut length. Then, workers would wrap the steel strips around the elevator guide rails and use pneumatic tensioning and locking tools to tighten and lock the strips. This traditional elevator guide rail steel strip packaging method has the following drawbacks: 1) The packaging team pre-cuts 1.8-meter or 2.2-meter steel strips and fastens them with buckles each shift. However, due to the different number of guide rails in a bundle on customer orders, a margin needs to be reserved for cutting the steel strips when packaging different quantities of guide rails. In most cases, the excess steel strip length that still needs to be cut after tightening is 0.26-0.3 meters, resulting in a steel strip waste rate of 14.4% (calculated based on 1.8-meter specifications), which is a serious waste of materials. 2) Several coiled steel strips placed on the spot are heavy, inconvenient to move, occupy production space, and are not conducive to efficient production; 3) Pneumatic tensioning and locking tools are standard parts that need to be connected to a pre-set air source via pipelines. The air source and pipeline need to be pre-set near the guide rail packaging station, which can easily interfere with other production equipment and affect the planning and deployment of the production line and subsequent adjustments. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a mobile steel strapping station for bundling and packaging elevator guide rails, thereby overcoming the deficiencies in existing technologies.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A mobile steel strapping station for bundling and packaging elevator guide rails includes several packing units and a high-pressure gas cylinder mounted on a handcart. Each packing unit includes a pair of U-shaped frames standing side by side on a trolley, a pair of low-position rollers positioned opposite each other on the trolley and located inside the U-shaped frames, and a pair of high-position rollers positioned opposite each other on the trolley and located outside the U-shaped frames. The pair of U-shaped frames, the pair of low-position rollers, and the pair of high-position rollers together form a steel strip placement space for placing a roll of steel strip for packing. The pair of low-position rollers jointly support the lower part of the steel strip roll, and the pair of high-position rollers respectively abut against both sides of the steel strip roll.

[0005] Furthermore, a pair of the lower rollers are respectively mounted on a pair of lower supports; a pair of the higher rollers are respectively mounted on a pair of higher supports.

[0006] Furthermore, a pair of mid-position arc-shaped springs are provided on the outer side of the pair of low-position supports. The mid-position arc-shaped springs are located between the U-shaped frames and remain in contact with the circumferential surface of the steel strip coil.

[0007] Furthermore, the high-position support is designed in an inverted L-shape, which is integrally connected by a vertical plate and a horizontal plate. The horizontal plate of the high-position support is provided with an assembly groove facing the steel strip horizontally. A return spring is provided in the assembly groove. A high-position roller seat is inserted into the open end of the assembly groove, and the high-position roller is installed on the high-position roller seat.

[0008] Furthermore, a measuring frame is fixedly installed on the top of the high-position support located on the left side of the U-shaped frame, and measuring rollers are installed on the measuring frame.

[0009] Furthermore, a scale is vertically installed on the side of the high-position support located on the left side of the U-shaped frame.

[0010] Furthermore, a cutting blade is also provided next to the high-position support located on the left side of the U-shaped frame, and the cutting blade is mounted on the handcart via a blade holder.

[0011] Preferably, the central arc-shaped spring is fixed to the handcart by a fixing plate.

[0012] Preferably, both the low-position bracket and the high-position bracket are fixedly installed on the handcart.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1) The mobile steel strapping station for bundling and packaging elevator guide rails in this case integrates all the work of packaging elevator guide rails into a handcart-type packaging station, which avoids material waste, reduces production costs, and does not occupy production space, thus promoting efficient production.

[0014] 2) The mobile steel strip packaging station for bundling elevator guide rails in this case has an assembly slot in the horizontal plate of its high-level support. A return spring is installed in the assembly slot, and a high-level roller seat is inserted into the open end of the assembly slot. A high-level roller is installed on the high-level roller seat. Under the elastic action of the return spring, the high-level roller seat has a certain elastic offset in the assembly slot, thereby ensuring that the high-level roller can elastically adhere to the circumferential surface of the steel strip roll within a certain offset range. This ensures that the high-level roller will not quickly separate from the steel strip roll as the outer diameter of the steel strip roll decreases with use, thus ensuring the stability of the steel strip roll rolling in the steel strip placement space to a certain extent.

[0015] 3) The mobile steel strip packaging station used for bundling and packaging elevator guide rails in this case has a middle arc-shaped spring piece on the outer side of its low-position support. When the high-position roller separates from the circumferential surface of the steel strip roll, the middle arc-shaped spring piece and the low-position roller can still abut against the circumferential surface of the steel strip roll, further ensuring the stability of the steel strip roll rolling in the steel strip placement space.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] Please also refer to Figure 1-6 This utility model provides a mobile steel strapping station for bundling and packaging elevator guide rails, including several packaging units a and high-pressure gas tanks b set on a handcart c.

[0023] Each packing unit a includes a pair of U-shaped frames 1 standing side by side on a handcart c, a pair of low rollers 2 positioned opposite each other on the handcart c and located inside the U-shaped frames 1, and a pair of high rollers 3 positioned opposite each other on the handcart c and located outside the U-shaped frames 1. The pair of U-shaped frames 1, the pair of low rollers 2, and the pair of high rollers 3 together form a steel strip placement space 4 for placing a roll of steel strip 100 for packing. The pair of low rollers 2 together support the lower part of the steel strip roll 100, and the pair of high rollers 3 respectively abut against the two sides of the steel strip roll 100. Under the rolling action of the low rollers 2 and the high rollers 3, when the end of the steel strip roll 100 is manually pulled out, the steel strip roll 100 can roll within the steel strip placement space 4, achieving the effect of labor-saving unwinding.

[0024] Furthermore, a pair of low-position rollers 2 are respectively mounted on a pair of low-position brackets 21; a pair of high-position rollers 3 are respectively mounted on a pair of high-position brackets 31; both the low-position brackets 21 and the high-position brackets 31 are fixedly mounted on the handcart c.

[0025] Furthermore, the high-position support 31 is designed in an inverted L-shape, consisting of a vertical plate and a horizontal plate integrally connected. The horizontal plate of the high-position support 31 has a horizontally oriented assembly groove facing the steel strip. A return spring 32 is installed in the assembly groove, and a high-position roller seat 33 is inserted into the opening end of the assembly groove. A high-position roller 3 is installed on the high-position roller seat 33. Under the elastic action of the return spring 32, the high-position roller seat 33 has a certain elastic offset in the assembly groove, thereby ensuring that the high-position roller 3 can elastically adhere to the circumferential surface of the steel strip roll 100 within a certain offset range. This ensures that the high-position roller 3 will not quickly separate from the steel strip roll 100 as the outer diameter of the steel strip roll 100 decreases with use, thus ensuring the stability of the steel strip roll 100 rolling within the steel strip placement space 4 to a certain extent.

[0026] Furthermore, a pair of mid-position arc-shaped spring pieces 5 are also provided on the outer side of a pair of low-position brackets 21. The mid-position arc-shaped spring pieces 5 are located between the U-shaped brackets 1 and remain in contact with the circumferential surface of the steel strip roll 100. The mid-position arc-shaped spring pieces 5 are fixed to the handcart c by a fixing plate. The function of the mid-position arc-shaped spring pieces 5 is as follows: Under normal conditions, a pair of low-position rollers 2, a pair of mid-position arc-shaped spring pieces 5 and a pair of high-position rollers 3 are respectively in contact with the circumferential surface of the steel strip roll 100. However, as the outer diameter of the steel strip roll 100 decreases with use, when the high-position rollers 3 in the high position separate from the circumferential surface of the steel strip roll 100, the mid-position arc-shaped spring pieces 5 and the low-position rollers 2 in the middle and low positions can still be in contact with the circumferential surface of the steel strip roll 100, thus continuing to ensure the stability of the steel strip roll 100 rolling within the steel strip placement space 4.

[0027] Furthermore, a measuring stand 61 is fixedly installed on the top of the high-position support 31 on the left side of the U-shaped frame 1, and measuring rollers 6 are installed on the measuring stand 61; a scale 7 is also vertically installed on the side of the high-position support 31 on the left side of the U-shaped frame 1; a cutting knife 8 is also installed next to the high-position support 31 on the left side of the U-shaped frame 1, and the cutting knife 8 is installed on the handcart c through a knife holder.

[0028] The mobile steel strapping station for bundling and packaging elevator guide rails described in this case has the following actual operating procedure: 1. The operator connects the existing pneumatic tensioning pliers (not shown) and locking pliers (not shown) to the quick-release connector of the air tank b on the handcart c via an air hose (not shown); 2. The operator places the new steel strip roll 100 into the steel strip placement space 4 on the handcart c. At this time, a pair of low rollers 2, a pair of middle arc-shaped springs 5 ​​and a pair of high rollers 3 are respectively attached to the circumferential surface of the steel strip roll 100. Then the operator pushes the handcart c to the side of the elevator guide rail to be packaged. 3. The operator pulls out the steel strip from the end of the steel strip roll 100 and makes the steel strip pass through the high roller 3, the length measuring roller 6 and the scale 7 located on the left side of the U-shaped frame 1 in sequence. The operator measures the length of steel strip required for packaging the elevator guide rail and marks it on the steel strip. The operator then cuts the steel strip with the cutter 8 and repeats the cutting to obtain the required amount of steel strip for packaging the elevator guide rail. 4. The operator uses tensioning pliers and locking pliers to tighten and lock the steel strip onto the bundled elevator guide rail, moves the handcart c and continues the packaging operation at the next station; when the steel strip roll 100 of the first packaging unit a is used up, the steel strip roll 100 of the second packaging unit a can be used for packaging.

[0029] Compared to existing technologies, the mobile steel strapping station for bundling and packaging elevator guide rails in this case integrates all the tasks of packaging elevator guide rails into a handcart-type packaging station, which avoids material waste, reduces production costs, does not occupy production space, and is conducive to efficient production.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
