Description

Technical Field

[0001] The utility model relates to the technical field of labeling equipment, in particular to a single-label picking device. Background Art

[0002] In the production of plastic bags, when applying large labels to wound bag rolls, it mainly relies on manual operation at present. However, manual labeling has low efficiency, high cost, and unstable quality. Therefore, mechanical labeling means need to be provided for supporting production. The large-label labeling machines available on the market mainly lay the large labels after gluing on the rolling path of the bag roll, and rely on the bag roll to automatically roll up the large label when passing by, so as to realize automatic large-label labeling. For the labeled bag rolls completed by such a labeling machine, the bag rolls are relatively loose, the label wrapping is relatively loose, and there are problems such as label skew. Therefore, the inventor provides a labeling method in which the large labels sent are wound and pasted by a method of clamping the bag roll with multiple rollers and driving it to actively roll, so as to achieve the purposes of dense bag rolls, tight labeling, and stable labeling. However, such winding and pasting requires the labels to be stored in stacks and delivered one by one for label input. Since the labels in the stack are in a stacked and abutted state by themselves, when picking up the single label at the top of the label stack, it is very easy to bring up one or two extra labels below due to the negative pressure effect. When the top label is input to the winding and pasting device, the lifted labels will fall on the input path, resulting in the inability to carry out subsequent labeling operations. Therefore, an effective means to avoid label lifting needs to be provided to solve the above problems. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a single-label picking device that can avoid lifting of extra labels, ensure single-label picking, and facilitate the normal progress of labeling operations.

A flexible paper-pushing component is installed on the frame at one end of the label storage device close to the labeling device, and the flexible paper-pushing component is connected with a paper-pushing driver.

[0005] As a preferred technical solution, the flexible paper-pushing component includes a paper-pushing seat, and a paper-pushing brush facing the labels on the label storage device is arranged on the paper-pushing seat.

[0006] As a preferred technical solution, the paper-pushing driver includes a paper-pushing driving cylinder with a vertically extending and retracting piston rod, and the paper-pushing seat is fixedly arranged on the piston rod of the paper-pushing driving cylinder.

Detailed implementation manners

[0021] The present utility model will be further described below in conjunction with the drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, those of ordinary skill in the art can recognize that, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the drawings and the description are illustrative in nature and are not used to limit the protection scope of the claims.

[0022] Embodiment 1: As Figures 1 to 5 collectively shown, the single - sheet label picking device is arranged between the label storage device 1 and the labeling device 2. There are stacks of labels 9 stored on the label storage device 1, and this device delivers the labels 9 on the label storage device 1 to the labeling device 2 in a single - sheet form for labeling use.

[0023] This device includes a frame 3. The frame 3 can be a frame shared with the label storage device 1 and / or the labeling device 2, or can be separately provided and relatively fixed to the frames of the above two devices, and there is no limitation here; its specific structure can be easily obtained by those skilled in the art according to conventional technical means, so it is not specifically shown in the figure.

[0024] A horizontally movable delivery seat 4 is installed on the frame 3. A delivery driver 41 is provided between the delivery seat 4 and the frame 3. The delivery driver 41 drives the delivery seat 4 to move horizontally to complete the horizontal delivery action of a single - sheet label 9. The delivery driver 41 can be implemented in one of the forms such as a driving cylinder, a motor with chain drive, a motor with gear - rack drive, etc. In this embodiment, only the driving cylinder is used for illustration.

[0025] A paper suction assembly 5 for adsorbing the uppermost label 9 on the label storage device 1 is installed on the delivery seat 4. When the delivery seat 4 is driven above the label 9, the paper suction assembly 5 sucks the uppermost label 9. In this embodiment, the paper suction assembly 5 includes a paper suction seat 51 vertically and movably installed on the delivery seat 4. A suction nozzle 52 is installed at the bottom of the paper suction seat 51. A lifting controller 53 is provided between the paper suction seat 51 and the delivery seat 4. The lifting controller 53 controls the paper suction seat 51 to descend to facilitate the suction nozzle 52 to suck the uppermost label 9. Of course, the suction nozzle 52 is connected to a vacuum pump and an adsorption control valve, which can be easily understood by those skilled in the art according to well-known technologies and will not be elaborated here and is not shown in the figure.

[0026] A flexible paper pushing assembly 6 is installed on the frame 3 at one end of the label storage device 1 close to the labeling device 2. The flexible paper pushing assembly 6 is connected to a paper pushing driver 65. During the process of the paper suction assembly 5 sucking the label 9, the paper pushing driver 65 drives the flexible paper pushing assembly 6 to flexibly push one end of the sucked label 9 close to the labeling device 2. This flexible pushing can push down the redundant labels 9 that are lifted without damaging the label 9 or causing deformation of the end of the label 9.

[0027] In this embodiment, the flexible paper pushing assembly 6 includes a paper pushing seat 61. A paper pushing brush 62 facing the label 9 on the label storage device 1 is provided on the paper pushing seat 61. The paper pushing driver 65 includes a paper pushing driving cylinder with a piston rod vertically extending and retracting. The paper pushing seat 61 is fixedly arranged on the piston rod of the paper pushing driving cylinder. The paper pushing brush 62 can easily extend between adjacent labels 9 due to its flexibility. When the paper pushing driver 65 drives the paper pushing seat 61 to move up and down, the free end of the paper pushing brush 62 extending between adjacent labels 9 drives the redundant labels 9 to fall, achieving the effect of pushing down. Multiple up and down movements can increase the probability of pushing down the redundant labels 9 and ensure that no redundant labels 9 are lifted.

[0028] In the use of this embodiment, glue is applied in advance at a specified position on the uppermost label 9 on the label storage device 1. The delivery driver 41 drives the delivery seat 4 to reach above the label 9. The lifting controller 53 drives the paper suction seat 51 to descend to the position where the suction nozzle 52 contacts the label 9, and the suction nozzle 52 adsorbs the uppermost label 9. The lifting controller 53 drives the paper suction seat 51 to rise. During this rising process, the paper pushing driver 65 drives the flexible paper pushing assembly 6 to reciprocate up and down two to three times, push down the redundant labels 9, and finally stop at a lower position to avoid the delivery path of the label 9. The pushed-down redundant labels 9 fall back onto the label storage device 1. Based on the presence of a limiting structure around the label 9 on the label storage device 1 (not shown in this embodiment), the pushed-down labels 9 can automatically align their postures.

[0029] After the paper suction base 51 is lifted to a specified height, the delivery driver 41 drives the delivery base 4 to move towards the labeling device 2, and the front end of the label 9 automatically enters between the bag roll 8 and the roller and is wound. During this winding process, the suction nozzle 52 maintains a negative pressure adsorption effect; based on the fact that the suction nozzle 52 provides an upward negative pressure suction force and the label 9 is horizontally input into the labeling device 2, a certain frictional resistance can be generated on the input of the label 9 at the suction nozzle 52, and this frictional resistance can play a role in tensioning the label 9. This tensioning effect can cooperate with the automatic winding at the labeling device 2 to make the bag roll 8 more compact and the labeling more tight. During the winding and labeling process, the paper dialing driver 65 drives the flexible paper dialing assembly 6 to return to the initial height. After this labeling is completed, the negative pressure adsorption at the suction nozzle 52 stops, and after the topmost label 9 on the label storage device 1 is glued again, the above-mentioned label 9 picking and delivering actions are repeated.

[0030] In this embodiment, the topmost label 9 is picked up by the negative pressure suction method. During the picking process, the paper dialing driver 65 drives the flexible paper dialing assembly 6 to perform a dialing action, and the redundant labels 9 brought up by the topmost label 9 fall back under this flexible dialing, avoiding the picking up of redundant labels 9, ensuring single-sheet picking, and facilitating the normal progress of the labeling operation.

[0031] Embodiment 2: As Figure 6 、 Figure 7 and Figure 8 collectively shown, the difference between this embodiment and Embodiment 1 is that: the flexible paper dialing assembly 6 includes a paper dialing roller 63 rotatably mounted on the frame 3, and a paper dialing brush 64 is fixedly provided on the roller surface of the paper dialing roller 63. The paper dialing driver 65 includes a paper dialing driving motor, and the power end of the paper dialing driving motor is power-connected to the paper dialing roller 63. During the process that the suction nozzle 52 sucks the topmost label 9 and the lifting controller 53 drives the paper suction base 51 to rise, the paper dialing driving motor drives the paper dialing roller 63 to rotate, and the rotation direction is the direction in which the paper dialing brush 64 can brush down the end of the label 9. The flexible continuous brushing action of this paper dialing brush 64 prompts the redundant labels 9 brought up to be brushed off, also avoiding the picking up of redundant labels 9, ensuring single-sheet picking, and facilitating the normal progress of the labeling operation.

[0032] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
