Multi-station automatic rotating labeler for stay cable hose

Abstract

This invention discloses a multi-station automatic rotary labeling machine for pull-wire hoses. Its advantages lie in the parallel installation of automatic rotary labelers and corresponding hook-rod ejectors on the frame, with a connector hook-rod ejector at each end of the frame. The automatic rotary labelers, hook-rod ejectors, and connector hook-rod ejectors are electrically connected to the main controller. After the long, thin hose is inserted, under the control of the main controller, each automatic rotary labeler first applies and cuts the tape to the hose at its designated location. Then, the hook-rod ejectors and connector hook-rod ejectors work together to eject the labeled pull-wire hose into the collection frame, satisfying the need for labeling at multiple locations and providing convenient automatic discharge.

Description

Technical Field

[0001] This invention belongs to the technical field of automotive parts manufacturing equipment, and in particular relates to a multi-station automatic rotary labeling machine for pull-wire hoses. Background Technology

[0002] In the cable industry, to facilitate identification of connections between lines, a label with markings is often wrapped around the cable. In labor-intensive enterprises, this is typically done manually, wrapping and sticking the tape to the cable. This method of labeling is inefficient and inconsistent. To improve production efficiency and standardize production, researchers have developed a Chinese utility model, "A Cable Labeling Machine," with publication number CN203601665U. However, this cable labeling machine can only semi-automatically process one label and is unsuitable for long, flexible cables requiring labeling at multiple locations, thus requiring improvement. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a multi-station automatic rotary labeling machine for pull-wire hoses that can automatically rotate and apply labels at multiple locations simultaneously and automatically discharge materials.

[0004] The technical solution adopted in this invention is as follows: a multi-station automatic rotary labeling machine for pull-wire hoses, comprising a frame, a main controller, and multiple automatic rotary labelers mounted side-by-side in the frame for applying and cutting tape to the outside of the pull-wire hoses. Each automatic rotary labeler has a hook-and-tube ejector on the side away from its tape, and a connector hook-and-tube ejector is provided at each end of the frame. A material collection frame for receiving labeled pull-wire hoses is provided next to the frame. The automatic rotary labelers, hook-and-tube ejectors, and connector hook-and-tube ejectors are electrically connected to the main controller.

[0005] Compared with the prior art, the advantages of this invention are that it sets up automatic rotary labelers and corresponding hook-rod ejectors side by side on the frame, and each end of the frame is provided with a connector hook-rod ejector. The automatic rotary labelers, hook-rod ejectors and connector hook-rod ejectors are electrically connected to the main controller. After the thin hose is inserted, under the control of the main controller, each automatic rotary labeler first completes the automatic rotary application of tape to the hose at its location and cuts the tape. Then, the hook-rod ejectors and connector hook-rod ejectors work together to eject the labeled hose into the collection frame, which meets the needs of labeling in multiple locations and the automatic discharge is more convenient.

[0006] Preferably, the automatic rotary labeler includes a base plate fixed to the frame, a slide plate slidably connected to the base plate and its push cylinder, a cutting cylinder mounted on the slide plate, a carrier plate connected to the push rod of the cutting cylinder, and an automatic rotary labeling and cutting mechanism mounted on the carrier plate. A guide rod is provided between the carrier plate and the slide plate. The automatic rotary labeling and cutting mechanism includes a gear frame, a gear protective cover, a servo motor, a gear transmission assembly, an output gear, a main shaft, a turntable, and a rocker arm. The gear frame is fixed to the carrier plate. The slots on the gear frame, gear protective cover, output gear, and main shaft all have upward openings. A clamping cylinder is provided at each end of the main shaft slot. One end of the main shaft is provided with a cutter on the side and a material picking assembly including a pair of first pressure belt rollers and a belt guide roller in the middle. A pair of second pressure belt rollers are provided on the other side of the cutter. The turntable has a radially extending positioning block opposite to the rocker arm. A photoelectric sensor is fixed on the gear frame above the positioning block and triggered when the protruding end of the positioning block rotates past. The push cylinder, cutting cylinder, servo motor, and photoelectric sensor are electrically connected to the main controller. This device is used to automatically rotate and apply adhesive tape and cut it to a fixed length. During automatic rotation and labeling, it first rotates in the opposite direction, with the first pressure roller near the rocker arm pressing the tape to adhere the tape head to the hose. When the positioning block triggers the photoelectric sensor, the tape head and hose already have good adhesion. Then, it rotates in the forward direction, stably driving the tape reel to rotate and wrap the tape around the hose. After the cutter cuts the tape, the second pressure roller presses the tape tail to adhere it. This results in a high degree of consistency in the application, thus avoiding the situation where, during direct forward rotation, the first pressure roller, away from the rocker arm, presses the tape head, causing it to lift up and form a bulge after being wrapped by the outer tape, resulting in insufficient label adhesion.

[0007] As an improvement, the automatic rotary labeler has a first hose support plate on the outside of the clamping cylinder away from the rocker arm, and the first hose support plate is fixed to the base plate. This is used to strengthen the support of the pull hose and avoid inaccurate label placement caused by the pull hose being too long and falling under gravity.

[0008] Preferably, the hook-shaped spring ejector includes a first spring cylinder and a first hook-shaped spring rod with one end hinged to the push rod of the first spring cylinder. The support rod of the first hook-shaped spring rod is fixed to the base plate, and the other end of the first hook-shaped spring rod is disposed between the clamping cylinder and the gear frame. The first spring cylinder is electrically connected to the main controller. The structure is simple, and the lever principle provides a large upward space, enabling rapid ejection of the pull cable hose.

[0009] Preferably, the connector hook spring device includes a second spring cylinder, a second hook-shaped spring rod with one end hinged to the push rod of the second spring cylinder, a second hose support plate, and an alignment vertical plate. The other end of the second hook-shaped spring rod and the alignment vertical plate are respectively located on the inner and outer sides of the second hose support plate. The structure is simple, and the lever principle provides a large upward space, enabling the rapid ejection of the hose head.

[0010] As an improvement, it also includes a tooling split button, a left tooling start button, and a right tooling start button, each electrically connected to the controller. The tooling split button is used to control the start of the left tooling by starting the 3-5 automatic rotary labelers and corresponding hook-and-tube ejectors on the left, as well as the connector hook-and-feeder on the left. The right tooling start button controls the start of the remaining automatic rotary labelers and corresponding hook-and-tube ejectors on the right, as well as the connector hook-and-feeder on the right. This makes the invention versatile; when the production demand for long draw hoses is low, it can be split into two tooling units for multi-station automatic rotary labeling and dispensing production of two medium-length draw hoses.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] This preferred embodiment is, for example Figure 1 and 2 The diagram shows a multi-station automatic rotary labeling machine for pull-wire hoses, comprising a frame 1, a main controller 2, a feeding frame 3 on one side of the frame 1 for placing unlabeled pull-wire hoses, nine automatic rotary labelers 4 arranged side-by-side within the frame 1 for applying and cutting tape to the pull-wire hoses, and a hook-and-stick ejector 5 on the side of each automatic rotary labeler 4 away from its tape. A connector hook-and-stick ejector 6 is located at each end of the frame 1, and a collection frame 7 on the other side of the frame 1 for receiving labeled pull-wire hoses. The automatic rotary labelers 4, hook-and-stick ejectors 5, and connector hook-and-stick ejectors 6 are electrically connected to the main controller 2. The number of automatic rotary labelers 4 and corresponding hook-and-stick ejectors 5 is designed according to the number of labels required for the longest pull-wire hose.

[0028] In this embodiment, the automatic rotating labeler 4 is as follows: Figures 3 to 5The diagram shows a base plate 4a fixed to a frame 1, a slide plate 4b slidably connected to the base plate 4a and its push cylinder 4c, a cutting cylinder 4d mounted on the slide plate 4b, a carrier plate 4e connected to the push rod of the cutting cylinder 4d, and an automatic rotating labeling and cutting mechanism mounted on the carrier plate 4e. A guide rod is provided between the carrier plate 4e and the slide plate 4b. The automatic rotating labeling and cutting mechanism includes a gear frame 4f, a gear protective cover 4g, a servo motor 4h, a transmission gear assembly consisting of a drive gear 4i, a first transmission gear 4j, and two second transmission gears 4k, an output gear 4m, a main shaft 4n, a turntable 4o, a rocker arm 4p, and a tape reel mounting shaft 4q. The gear frame 4f is fixed to the carrier plate 4e. The gear frame 4f, the gear protective cover 4g, and the main shaft 4n are all provided with upward-facing tube grooves. A clamping cylinder 4r is provided at each end of the tube groove of the main shaft 4n. One end of the main shaft 4n is connected to the output gear. A material handling assembly consisting of a pair of first pressure belt rollers 4s and a belt guide roller 4t is fixed on the frame block at the other end of the main shaft 4n on both sides of the tube groove. The belt guide roller 4t is located above the first pressure belt roller 4s near the rocker arm 4p to keep the belt position from moving too much when it is cut, and to prevent the belt from sticking to the main shaft 4n or other parts. The cutter 4u is located on the outside of the other first pressure belt roller 4s. A pair of second pressure belt rollers 4v are located on the other side of the cutter 4u. The cutter 4u and the second pressure belt rollers 4v are also mounted on the frame block. The turntable 4o has a positioning block 4w extending radially in the opposite direction of the rocker arm 4p. A photoelectric sensor 4x is fixed on the gear frame 4f above the positioning block 4w, which is triggered when the protruding end of the positioning block 4w rotates past. The push cylinder 4c, the cutting cylinder 4d, the servo motor 4h and the photoelectric sensor 4x are electrically connected to the main controller 2. A limit switch electrically connected to the main controller 2 is also provided for precise control of the displacement of the cutting cylinder 4d or the push cylinder 4c push rod at a fixed distance. A second pressure roller 4v ensures stable adhesion between the tape and the pull hose when the cutter 4u cuts the tape. A protective plate and counterweight are installed below the base plate 4a.

[0029] As an improvement, the automatic rotary labeler 4 has a first hose support plate 4z on the outside of the clamping cylinder 4r, away from the rocker arm 4p. The first hose support plate 4z is fixed to the base plate 4a. This provides more support for the hose and prevents inaccurate marking position due to the hose's weight.

[0030] The hook-shaped spring tube device 5 includes a first spring cylinder 51 and a first hook-shaped spring rod 52 with one end hinged to the push rod of the first spring cylinder 51. The first support rod 53 of the first hook-shaped spring rod 52 is fixed to the base plate 4a, and the other end of the first hook-shaped spring rod 52 is disposed between the clamping cylinder 4r and the gear frame 4f. The first spring cylinder 51 is electrically connected to the main controller 2.

[0031] The connector hook-rod feeder 6 includes a second feed cylinder 61, a second hook-shaped feed rod 62 with one end hinged to the push rod of the second feed cylinder 61, a second hose support plate 63, and an alignment vertical plate 64. The second support rod 65 of the second hook-shaped feed rod 62 is fixed to the collection frame 7 or the frame 1 through a connecting rod 66. The second hose support plate 63 and the alignment vertical plate 64 are fixed to the frame beam of the frame 1 through a mounting plate. The other end of the second hook-shaped feed rod 62 and the alignment vertical plate 64 are respectively located on the inner and outer sides of the second hose support plate 63.

[0032] In addition, it also includes a tooling split button 8, a left tooling start button 9, and a right tooling start button 10, which are electrically connected to the main controller 2 respectively. The tooling split button 8 is used to control the start of the left tooling start button 9 to start the 3 to 5 automatic rotary labelers 4 and the corresponding hook tube ejectors 5 on the left and the joint hook tube ejector 6 on the left. The right tooling start button 10 is used to control the start of the remaining automatic rotary labelers 4 and the corresponding hook tube ejectors 5 on the right and the joint hook tube ejector 6 on the right.

[0033] In this invention, when the automatic rotating labeler 4 is working, the servo motor 4h first drives the output gear 4m in the reverse direction through the transmission gear assembly, which drives the material picking component at the end of the main shaft 4n to rotate. The first pressure belt roller 4s near the rocker arm 4p presses the tape head below the pull tube. When the photoelectric sensor 4x is triggered when the protruding end of the positioning block 4w rotates past, the tape head is pasted to the pull tube. When the main controller 2 receives the signal from the photoelectric sensor 4x, it controls the servo motor 4h to adjust the rotation direction. The servo motor 4h drives the output gear 4m in the forward direction through the transmission gear assembly. After the normal tape winding is completed, the cutting cylinder 4d retracts and drives the automatic rotating label cutting mechanism downward. When the pushing cylinder 4c pushes the slide plate 4b into place, the cutting cylinder 4d extends upward and the cutter 4u cuts the tape. The second pressure belt roller 4v presses the cut tape tail. Finally, the main controller 2 controls the cutting cylinder 4 and the pushing cylinder 4c to reset.
