Description

Technical Field

[0001] This utility model relates to the field of automatic packaging equipment, and more specifically, to a four-label station automatic switching labeling machine. Background Technology

[0002] Currently, in industries such as food, beverage, cosmetics, and pharmaceuticals, it is necessary to simultaneously affix labels to two opposite sides of square bottles. Manually affixing labels is time-consuming and labor-intensive, and the adhesion and consistency are not high. Therefore, automatic labeling machines have been widely used, replacing the previous manual labeling methods and solving the problems of low labeling efficiency, slow speed, and low labeling accuracy.

[0003] An automatic labeling machine is a device that uses adhesive to affix paper or metal foil labels to designated packaging containers. It can perform various operations such as flat labeling, single-sided or multi-sided labeling, cylindrical labeling, partial or full coverage of cylindrical surfaces, and labeling of recessed and corner areas. The workflow is as follows: the product enters the labeling area via a conveyor belt. After the sensor detects the product's arrival, the control system triggers the labeling head to separate and pick up a single label from the label roll, then precisely affixes it to the designated position on the product. The labeled product continues to move forward along the conveyor belt.

[0004] Existing bottle labeling machines in China typically do not have the function of changing labels without stopping the machine. After each roll of labels is applied, the entire line needs to be stopped to change the labels, which will cause a waste of time in the production process and reduce the output of the entire line.

[0005] To address the aforementioned issues, it is necessary to provide an automatic switching labeling machine for four labeling stations to solve these problems. Utility Model Content

The utility model will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of this utility model and should not be used to limit the scope of protection of this utility model.

[0040] Example 1, see Figure 1 and Figure 2 An automatic labeling machine with four labeling stations includes a frame 1, a conveyor frame 2 mounted on the frame 1, and a bottle separator assembly 3, a correction assembly 4, a first labeling station assembly 5, a second labeling station assembly 6, and a label pressing assembly 7 arranged sequentially along the conveying direction of the conveyor frame 2. The bottle separator assembly 3 divides the square bottles entering the conveyor frame 2 into equal intervals. After entering the correction assembly 4, the bottle separator assembly applies pressure to the square bottles to shape them into a regular shape, preparing them for labeling.

[0041] The first labeling station component 5 includes a first left labeling station 51 and a first right labeling station 52 symmetrically distributed on both sides of the conveyor frame 2. The second labeling station component 6 includes a second left labeling station 61 and a second right labeling station 62 symmetrically distributed on both sides of the conveyor frame 2. The square bottle is simultaneously labeled by the left and right labeling stations distributed on both sides of the conveyor frame, thus completing the labeling of both sides of the bottle. After the labeling is completed, it enters the label pressing component 7 to press the label on the bottle flat.

[0042] The frame 1 is also equipped with a control box assembly 8. The conveyor frame 2, bottle separator assembly 3, calibration assembly 4, first labeling station assembly 5, second labeling station assembly 6, and label pressing assembly 7 are all electrically connected to the control box assembly 8. The first labeling station assembly 5 and the second labeling station assembly 6 are each equipped with a missing label detection sensor and a bottle detection photoelectric sensor, both of which are electrically connected to the control box assembly 8. When the bottle detection photoelectric sensor detects a square bottle, the control box assembly 8 controls the corresponding left and right labeling stations to dispense labels simultaneously. Based on the signal fed back by the missing label detection sensor, the control box assembly 8 simultaneously controls the working status of the first labeling station assembly 5 and the second labeling station assembly 6. The labeling station assembly that has issued a missing label signal is adjusted to standby mode, while the labeling station assembly that has not issued a missing label signal is adjusted to working mode. The labeling station with missing labels is manually refilled with labels, and then the machine waits for the control box assembly 8 to take control.

[0043] For example, when the label shortage detection sensor of the first labeling station component 5 sends a label shortage signal, the control box component 8 issues a command to stop the rotation of the bottle separator component 3, preventing the bottles from entering the labeling station. After the remaining bottles are labeled, the control box component 8 adjusts the working state of the first labeling station component 5 to the standby state and adjusts the second labeling station component 6 to the working state. After the control box component 8 confirms that the adjustment is completed, the bottle separator component 3 is started. The worker fills the labeling station of the first labeling station component 5 and waits for further control from the control box component 8.

[0044] Preferably, see Figure 3 and Figure 4 The correction component 4 includes left and right correction components 41 and upper pressure correction components 42. The left and right correction components 41 are symmetrically arranged on both sides of the conveyor frame 2, and the upper pressure correction components 42 are arranged above the conveyor frame 2.

The first guide seat 41-1 is fixedly connected to the output ends of the first left and right adjustment part 41-2 and the first lifting adjustment part 41-3, respectively.

[0046] The pressure correction component 42 includes a second guide seat 42-1, a second left-right adjustment part 42-2, and a second lifting adjustment part 42-3. The second guide seat 42-1 is equipped with a second guide chain 42-4 that is synchronized with the speed of the conveyor frame 2. The second left-right adjustment part 42-2 and the second lifting adjustment part 42-3 are fixed on the conveyor frame 2, and the second guide seat 42-1 is fixedly connected to the output ends of the second left-right adjustment part 42-2 and the second lifting adjustment part 42-3, respectively. The correction component can simultaneously apply pressure to the bottle, causing it to form a regular shape, which can effectively improve the quality of labeling.

[0047] Preferably, each of the first left marker station 51, the first right marker station 52, the second left marker station 61, and the second right marker station 62 is equipped with a marker dispensing button 9. An electric marker dispensing button is provided for convenient marker station label replacement or adjustment.

[0048] Preferably, see Figure 5 The first left marker station 51, the first right marker station 52, the second left marker station 61 and the second right marker station 62 have the same structure and are all equipped with a base adjustment component 11 and a lifting adjustment component 12.

The X-axis adjustment assembly 11-2 is fixedly mounted on the fixed base 11-1, and the 11-3 is fixedly mounted on the X-axis adjustment assembly 11-2. The 11-3 is fixedly connected to the corresponding marker station. The base adjustment assembly and lifting assembly allow for adjustable spatial position of the marker station, making it more flexible to use.

[0050] X-axis adjustment assembly 11-2 includes two X-axis locking seats 11-2-1 fixed on the fixed base 11-1 and an X-axis adjustment top plate 11-2-2 rotatably mounted on the fixed base 11-1. The two X-axis locking seats 11-2-1 are provided with longitudinal slots, and an X-axis adjustment end plate 11-2-3 is connected between the two slots.

An X-axis lead screw adjustment assembly 11-2-5 is provided between the X-axis adjustment end plate 11-2-3 and the fixed base 11-1. The X-axis adjusting end plate 11-2-3 is threadedly connected to an X-axis tilt knob 11-2-7, which passes through the X-axis adjusting end plate 11-2-3 and connects to the fixed base 11-1. The X-axis lead screw adjusting assembly 11-2-5 is a handwheel adjusting device, which allows for adjustable forward, backward, left, and right travel of the marker station via the handwheel adjustment structure, and adjustable tilt angle of the marker station via the tilt knob, adapting to various types of bottle bodies.

[0051] Y-axis adjustment component 11-3 is positioned above X-axis adjustment top plate 11-2-2 and has the same structure as X-axis adjustment component 11-2, with their directions perpendicular to each other.

[0052] A cylinder 11-2-6 is also fixedly installed on the X-axis adjusting end plate 11-2-3, and the output end of the cylinder 11-2-6 is fixedly connected to the X-axis adjusting top plate 11-2-2. The cylinder is configured to drive the overall displacement of the station, making operation more convenient.

[0053] In this embodiment, by setting up two labeling station components and four labeling stations, simultaneous labeling of both sides of the bottle can be achieved. When the label shortage detection sensor detects that the labels at the first labeling station are exhausted, the second labeling station component is activated to perform the labeling operation. At this time, the first labeling station component can be manually replaced. This cycle can be repeated to replace labels without stopping the machine, saving label replacement time and effectively improving labeling efficiency.
