Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, and in particular to a packaging, conveying, and positioning device for pharmaceutical packaging boxes. Background Technology

[0002] The final steps in the pharmaceutical production process are packaging and coding the medicine boxes. The packaging operation is to use a packaging machine to tie and secure the boxes with straps, usually using a two-horizontal-one-vertical packaging method. Coding is done by spraying codes onto the outer surface of the boxes after packaging to print information such as batch number and production time.

[0003] A typical packaging and coding system usually includes two conveyor belts with a gap between them for the packaging straps to be tied. The boxes are packaged when they are transported to the junction of the two conveyor belts. After the boxes are packaged horizontally, they are turned 90° by a box turning mechanism. Then the two conveyor belts are transported in opposite directions, and the boxes are packaged vertically. Finally, the packaged boxes are printed with codes by a coding machine.

[0004] In the above system, since two conveyor belts are inevitably used, and different conveyor belts use different drive systems, there are deviations between the drive systems, which leads to deviations in the conveying speed of the two conveyor belts. This will result in different boxes being marked at different positions, making it impossible to fix a uniform marking position. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present invention provides a medicine packaging box packing, conveying and positioning device.

[0006] The present invention provides a pharmaceutical packaging box packing, conveying, and positioning device, which adopts the following technical solution:

[0007] A packaging and positioning device for pharmaceutical boxes includes a first conveyor belt and a second conveyor belt arranged in sequence. A packaging machine is installed at the junction of the first and second conveyor belts. An inkjet printer is installed next to the first conveyor belt. A box turning mechanism is installed on the end of the second conveyor belt away from the first conveyor belt. A sensor mechanism for measuring the conveying speed of the second conveyor belt is installed on the other end of the second conveyor belt away from the first conveyor belt. The sensor mechanism includes an encoder for electrical connection with a control system that controls the inkjet printer. A roller is installed on the encoder for rolling friction contact with the surface of the second conveyor belt.

[0008] By adopting the above technical solution, the conveying speed of the second conveyor belt is measured by the encoder and roller, and then fed back to the control system to control the inkjet printer's inkjet timing, thereby ensuring the consistency of the inkjet printing position of each box.

[0009] Optionally, the sensor mechanism also includes a connecting frame mounted on the second conveyor belt frame. A fixing plate is mounted on the connecting frame, and a connecting shaft is fixed to the side of the fixing plate opposite to the connecting frame. A mounting plate is mounted on the connecting shaft, which is arranged parallel to the conveying direction of the second conveyor belt. The encoder is mounted on one side of the mounting plate, and the roller is located on the other side of the mounting plate.

[0010] Optionally, the mounting plate is rotatably connected to the connecting shaft. Both the mounting plate and the fixing plate are equipped with positioning screws, with the positioning screw on the fixing plate located below the connecting shaft. A tension spring is installed between the two positioning screws.

[0011] By adopting the above technical solution, the tension spring elastically drives the mounting plate to rotate towards the second conveyor belt, so that the roller is always in effective contact with the surface of the second conveyor belt.

[0012] Optionally, the connecting frame includes a connecting plate with a vertically arranged elongated hole, and the connecting plate and the fixing plate are fixed by screws passing through the elongated hole.

[0013] Optionally, the bottom of the connecting plate is fixed to the second conveyor frame with screws.

[0014] Optionally, a C-shaped plate is fixed to the bottom of the connecting plate. The C-shaped plate can be detachably fastened to the second conveyor belt frame. A Torx screw is vertically threaded onto the bottom arm of the C-shaped plate. A pressure plate for abutting and fixing the second conveyor belt frame is vertically fixed to the top of the Torx screw.

[0015] By adopting the above technical solution, it is convenient to install, fix or disassemble the sensor mechanism as a whole, improve the operation efficiency, and the position of the sensor mechanism on the second conveyor belt can be easily adjusted without drilling screw holes in the second conveyor belt frame, thereby reducing damage to the structure.

[0016] Optionally, the box steering mechanism includes an L-shaped lever, which is arranged parallel above the second conveyor belt. An L-shaped connecting rod is vertically fixed to the end of the lever. The connecting rod is rotatably mounted on the frame of the second conveyor belt via a rotating seat. A telescopic member for driving the connecting rod to rotate is hinged below the second conveyor belt. The telescopic member is hinged to the connecting rod. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 The present invention will be described in further detail below.

[0024] This utility model discloses a packaging, conveying, and positioning device for pharmaceutical packaging boxes. Example 1

[0025] Reference Figure 1 The pharmaceutical packaging box packing and conveying positioning device includes a first conveyor belt 1, a second conveyor belt 2 at the end of the first conveyor belt 1, a gap between the second conveyor belt 2 and the first conveyor belt 1, a packing machine 3 at the junction of the first conveyor belt 1 and the second conveyor belt 2, and a coding machine 4 placed next to the first conveyor belt 1.

[0026] Reference Figures 1-3 A box-shaped turning mechanism 5 is installed on the side of the second conveyor belt 2 away from the end of the first conveyor belt 1. The box-shaped turning mechanism 5 includes an L-shaped lever 50, which is set parallel to the top surface of the second conveyor belt 2. One end of the lever 50 is vertically fixed to an L-shaped connecting rod 51. The connecting rod 51 is rotatably mounted on the frame of the second conveyor belt 2 through a rotating seat 52. A telescopic member 53 for driving the connecting rod 51 to rotate is installed at the bottom of the second conveyor belt 2. In this embodiment, the telescopic member 53 is a cylinder. The cylinder body is hinged to the crossbeam at the bottom of the frame of the second conveyor belt 2, and the piston rod of the cylinder is hinged to the bottom end of the connecting rod 51.

[0027] Reference Figure 1 and Figure 4A sensor mechanism 6 for measuring the conveying speed of the second conveyor belt 2 is installed on the other side of the end away from the first conveyor belt 1. The sensor mechanism 6 includes a connecting frame 60, which includes a connecting plate 600. Two elongated holes 6000 are vertically opened on the connecting plate 600. The bottom of the connecting plate 600 is vertically attached to the side of the frame of the second conveyor belt 2 and fixed by screws. A fixing plate 61 is installed on the top of the connecting plate 600 by screws. A connecting shaft 62 is vertically fixed to the side of the fixing plate 61 away from the connecting plate 600. An mounting plate 63 is rotatably installed on the connecting shaft 62. The length direction of the mounting plate 63 is the same as the conveying direction of the second conveyor belt 2.

[0028] Reference Figure 4 An encoder 64 is fixedly mounted on one side of the mounting plate 63. The encoder 64 is electrically connected to the control system for controlling the inkjet printer 4. A roller 65 is provided on the other side of the mounting plate 63. The roller 65 is mounted on the rotating shaft of the encoder 64 and makes rolling contact with the surface of the second conveyor belt 2 so that the encoder 64 can measure the conveying speed of the second conveyor belt 2 and feed it back to the control system. The control system calculates and determines the inkjet printing time based on the conveying speed of the second conveyor belt 2 so as to dynamically control the consistency of the inkjet printing position of each box.

[0029] Reference Figure 4 Positioning screws 66 are installed on both the mounting plate 63 and the fixing plate 61. The positioning screw 66 on the fixing plate 61 is located below the connecting shaft 62. A tension spring 67 is installed between the two positioning screws 66. The tension spring 67 has a downward elastic pulling force on the mounting plate 63 to ensure that the roller 65 is in constant rolling contact with the surface of the second conveyor belt 2. The roller 65 can be a rubber wheel.

[0030] The implementation principle of Embodiment 1 of this utility model is as follows: the box is first transported from the first conveyor belt 1 to the second conveyor belt 2. The two conveyor belts are in the same direction. When the box is transported to the position of the packing machine 3, two transverse packing operations are performed in sequence. Then the box is transported by the second conveyor belt 2 to the vicinity of the box turning mechanism 5. When the box contacts the lever 50, the telescopic member 53 drives the lever 50 to rotate, so that the box is turned 90°.

[0031] Subsequently, the second conveyor belt 2 and the first conveyor belt 1 transport the boxes in opposite directions. When the box is transported to the packaging machine 3 again, a longitudinal packaging operation is performed. Finally, the box is transported by the first conveyor belt 1 and printed at the inkjet printer 4. During this production process, the encoder 64 and roller 65 of the sensor mechanism 6 work together to measure the conveying speed of the second conveyor belt 2 and transmit it to the control system.

[0032] The control system calculates and controls the inkjet printer 4 based on this to dynamically control the consistency of the inkjet printing position of each box. This pharmaceutical packaging box packing and conveying positioning device can effectively solve the problem of inconsistent inkjet printing positions of different boxes and meet the actual production needs of pharmaceutical companies. Example 2

[0033] Reference Figure 5 The difference between this embodiment and embodiment 1 is that the connecting frame 60 in this embodiment includes a connecting plate 600, a C-shaped plate 601, a Torx screw 602, and a pressure plate 603. The connecting plate 600 is bolted to the fixing plate 61. The connecting plate 600 is vertically fixed to the top arm of the C-shaped plate 601. The C-shaped plate 601 is horizontally detachably fastened to the frame of the second conveyor belt 2. The Torx screw 602 is vertically threaded to the bottom arm of the C-shaped plate 601. The pressure plate 603 is vertically fixed to the top of the Torx screw 602 and is used to abut and fix to the bottom surface of the frame of the second conveyor belt 2.

[0034] The implementation principle of Embodiment 2 of this utility model is as follows: the operator can fasten the C-shaped plate 601 onto the frame of the second conveyor belt 2, and then tighten the Torx screw 602 to make the pressure plate 603 abut against and fix the frame of the second conveyor belt 2, thereby facilitating the overall installation, fixing or disassembly of the sensor mechanism 6, improving operating efficiency, and the position of the sensor mechanism 6 on the second conveyor belt 2 can be conveniently adjusted as needed without drilling screw holes in the frame of the second conveyor belt 2, so as to reduce damage to the structure.

[0035] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
