Description

Technical Field

[0001] The invention relates to the technical field of automation equipment, and in particular to a label counting device. Background Art

[0002] There are many kinds of label counting equipment on the market, including labeling machines, label peeling machines, etc. They use sensors to automatically calculate the number of labels pasted or peeled by the equipment. Generally speaking, the label materials used by these devices are rolls of fixed-quota labels produced by label manufacturers, and there is no need to count the quantity. However, in actual production applications, the factory material management unit will issue labels based on the number of labels used for products produced on the production line. However, most of the label materials supplied by label manufacturers are huge rolls of labels. During use, only a part of the rolls of labels is often used. This requires manual counting of the rolls of labels and counting a certain number of labels, but this method is time-consuming and labor-intensive, which restricts the work efficiency of personnel. For this purpose, a label counting device that uses the principle of mechanical levers for counting is designed.

It can only count labels with a small width range, and the unwinding space is limited and the total count is low. After the counting is completed, the label attachment paper needs to be manually cut, which is time-consuming and labor-intensive, and restricts the improvement of labor efficiency.

Among them, the driving part 24 is composed of an auxiliary guide roller 4, a driving motor 6, a pressure wheel bracket 23, a pressure wheel 25, a driving roller 26, a power synchronous pulley 29, a pressure wheel tension spring 32, a synchronous belt 33, a driving synchronous pulley 34, a synchronous belt pressure guide wheel 35, and a material receiving synchronous pulley 36. The driving motor 6 is fixed on the frame 37 to drive the synchronous belt 33 to move, thereby driving the driving synchronous pulley 34 and the synchronous belt pressure guide wheel 35 to move. The pressure wheel 25 is fixed on the pressure wheel bracket 23 and is tangent to the outer circle of the driving roller 26. This part can realize the functions of loosening, tightening, and conveying the rolled label material, making preliminary preparations for counting and cutting. Among them, the material receiving part 22 is composed of a clamping pliers 20, a winding roller 21, and a material receiving synchronous pulley 36. One end of the clamping pliers 20 is inserted into the winding roller 21, and the other end is pressed against the surface of the winding roller 21, which is used to realize the pressing and fixing of the label base paper and the label winding function when counting the roll label material, so that the label material is cylindrical, which is convenient for storage and transportation.Among them, the control part 17 is composed of a digital tube display 12, a touch screen 14, a start button 15, an emergency stop button 16, a stop button 18, a power switch 19, and an electric control box 38. The touch screen 14, the start button 15, the emergency stop button 16, the stop button 18, and the power switch 19 are embedded in the surface of the electric control box 38. The electric control box 38 is equipped with control circuit components, etc. This part is used to realize the counting data analysis and processing of the label counting device, data display, label counting mode selection, external control and other functions, and the actual value of the label count is truly fed back to the user.

[0062] Run the design:

[0063] Figure 3 The automatic counting operation process of the label counting device of the present invention is shown in FIG. Figure 1 , Figure 2 It can be seen that the rolled label 39 is fixed on the unwinding roller 2 by means of the pre-tensioning rod 3, and the strip material to which the label is attached, the backing paper and the label are attached, passes through the auxiliary guide roller 4, the driving roller 26, the pressure roller 25, the auxiliary guide roller 4, the scale plate 13, the auxiliary guide roller 4, and the winding roller 21 in sequence, and finally the backing paper part of the label is fixed on the winding roller 21 by means of the clamping pliers 20.

[0064] like Figure 3 , Figure 1 The label strip material shown is led out from the unloading part, and the driving motor 6 of the driving part drives the power synchronous pulley 29, the synchronous belt 33, the driving synchronous pulley 34, and the material receiving synchronous pulley 36 to move, wherein the driving synchronous pulley 34 drives the driving roller 26 to rotate, and the driving roller 26 uses friction to move the label attached base paper, and at the same time, the winding roller 21 of the material receiving part drives the label attached base paper to perform the material receiving action. Among them, the auxiliary guide roller 4 and the pressure wheel 25 are used to adjust the tightness of the label attached base paper. The pressure wheel 25 can rotate around the pressure wheel bracket 23, and the wrap angle size of the contact point between the label attached base paper and the driving roller 26 can be changed to adjust the contact surface size, so as to adjust the size of the driving friction force, so that the label attached base paper is fully in contact with the driving roller 26 and the pressure wheel 25, and will not be loose. The position of the auxiliary guide roller 4 can be adjusted according to the actual usage to meet the requirements of labels of different types, widths and sizes.

[0065] like Figure 4The figure shows the working principle diagram of the mechanical displacement amplifying rod of the label counting device. The strip label moves onto the scale plate 13 to ensure that the label is always in a flat state. Then the mechanical displacement amplifying rod 7 uses the lever principle to amplify the discontinuous change of the thickness displacement of the label 40 and transmits it to the micro displacement sensor 5 in real time. The number of discontinuous changes in the thickness displacement of the label 40 is used to monitor the number of labels counted in real time, and the known count number is displayed through the digital tube display 12. When the number reaches the expected set number, the drive motor 6 stops working, and the cutting part starts working at the same time. Figure 2 and Figure 5 As shown, the cutting tool 11 is closed under the pushing action of the push-pull electromagnet 28, so as to cut the label attachment base paper, and realize automatic counting and cutting of labels. This counting method using the mechanical displacement amplifying rod 7 can realize the counting of label materials of non-transparent label attachment base paper and transparent label attachment base paper of different widths and sizes, and has simple operation, wide application range, strong versatility, and well meets the needs of users.

This part can realize the placement and unwinding of roll label materials and the determination of the amount of residual material of the roll label materials. The counting part 8 is composed of a micro-displacement sensor 5, a mechanical displacement amplifying rod 7, a label sensor 9, a digital tube display 12, and a scale plate 13. The scale plate 13 is fixed between two auxiliary guide rollers 4, and the connection is smooth and gapless.

[0070] Run the design:

[0071] The automatic counting method of the mechanical displacement amplifying rod 7 used in Example 1 is replaced by automatic counting using the tag sensor 9, such as Figure 5 As shown, the label sensor 9 realizes automatic label counting by detecting the change in the transmittance of the label attachment backing paper. However, this method cannot be applied to the counting of label materials with non-transparent label attachment backing paper, which has certain limitations. The push-pull electromagnet 28 in the cutting part 10 can be replaced by a cylinder to push the cutting tool 11 to close, so as to realize automatic cutting of the label attachment backing paper.

[0080] 2. The lever-type mechanical amplification structure in the label counting device is used to magnify the gap between adjacent labels, and the micro-displacement sensor is used to measure the displacement change value of the lever-type mechanical amplification structure, so as to count the labels with opaque bottom paper, thereby expanding the scope of application of label counting and improving the work efficiency of employees;
