Description

Technical Field

[0001] The utility model relates to the technical field of bottle feeding of a tunnel oven, in particular to a bottle pushing device used for feeding bottles into a tunnel oven. Background Art

[0002] Tunnel ovens are widely used in the fields of biotechnology, medicine and health, pharmaceutical industry, etc. Its main function is to dry and sterilize the pharmaceutical packaging containers from the bottle washing process to ensure the sterility of the pharmaceutical packaging containers.

[0003] Pharmaceutical packaging containers, i.e. medicine bottles, lose their power to move forward after leaving the bottle washer. Since the mesh belt of the tunnel oven is driven by a circular sprocket, a bridge plate must be added at the connection with the bottle feeding mesh belt of the bottle washer. When the medicine bottles coming from the bottle washer outlet are continuous, the medicine bottles on the bridge plate will enter the oven due to the squeezing and pushing action of the medicine bottles that are constantly moving forward at the rear, and participate in the normal sterilization process. However, when the entire production batch is about to end and the last batch of medicine bottles arrives at the bridge plate, these medicine bottles cannot smoothly enter the tunnel oven due to the loss of the squeezing and pushing action of the medicine bottles at the rear, and they do not have the opportunity to be sterilized. In addition, the medicine bottles left on the bridge plate will also hinder the closing of the tunnel oven lifting door, making it impossible to carry out the sterilization work of the medicine packaging containers in the tunnel oven smoothly.

DETAILED DESCRIPTION

[0034] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.

[0035] As shown in the figure, the utility model provides a bottle pushing device for feeding bottles into a tunnel oven, comprising a bottle washing machine bottle discharging mesh belt assembly 1, a bottle pushing assembly 2, a bottle pushing device laminar flow frame assembly 3, and a tunnel oven decorative plate assembly 4.

[0036] The bottle discharging mesh belt assembly 1 of the bottle washing machine is installed between the bottle washing machine and the bottle pushing assembly 2. The power mesh belt thereon can provide power for the medicine packaging container to move forward, and send the cleaned medicine packaging container out of the bottle washing machine and into the bottle pushing assembly 2.

[0037] The linear guide rail bracket 202 in the bottle pushing assembly 2 is fastened on the bottom plate 201 by bolts, and a pair of linear guide rails 203 are installed on the upper surface of the linear guide rail bracket 202. The bottle pushing rod bracket 204 is fastened by bolts on the mounting block of the linear guide rail 203. The nut of the ball screw 205 is fastened by bolts at the central position of the bottle pushing rod bracket 204. The front end of the ball screw 205 is fixed with a ball screw transmission gear 206 by a key and a pin. The ball screw transmission gear 206 is meshed with the servo motor transmission gear 207 below. The servo motor transmission gear 207 is fixed to the output shaft of the servo motor 208 by a key and a pin. After the servo motor 208 is started, the servo motor transmission gear 207 can be driven to rotate. Due to the gear meshing relationship, the ball screw transmission gear 206 rotates, driving the ball screw 205 to rotate, and the bottle pushing rod bracket 204 moves in the front and rear horizontal direction, providing horizontal power for pushing the bottle. At this time, the linear guide rail 203 plays the role of balancing, orienting and reducing friction.

[0038] A rotatable bottle pushing rod 209 is installed in the bearing seats at the two ends of the bottle pushing rod bracket 204, and a sensing block 210 is installed at one end of the rotating shaft of the bottle pushing rod 209 through a set screw. A set of proximity switch components 211 is installed in front of the sensing block 210 through a bracket, and the other end of the rotating shaft of the bottle pushing rod 209 is fixedly connected to the output shaft of the bottle pushing rod flip reduction motor 222 through a key and a pin. One side of the linear slide bracket 202 is fastened with a mesh belt drive motor 216 by bolts, and the sprocket at the output end of the mesh belt drive motor 216 transmits power to the bottle pushing device conveying mesh belt 214 through a mesh belt drive roller chain 217. The front of the bottle pushing device conveying mesh belt 214 is connected to the tunnel oven bottle inlet bridge plate 215, and a water receiving tray 218 is installed below the bottle pushing device conveying mesh belt 214. A pair of optical fiber sensors 211 are installed on both sides of the bottle pushing device conveying mesh belt 214. The mesh belt drive motor 216 is started, and the power is transmitted to the bottle pushing device conveying mesh belt 214 through the mesh belt drive roller chain 217. The upper surface of the bottle pushing device conveying mesh belt 214 moves in the horizontal direction, further providing power for the medicine bottle 212 placed thereon to enter the tunnel oven. The medicine bottle 212 enters the tunnel oven through the front of the bottle pushing device conveying mesh belt 214 docking the tunnel oven bottle inlet bridge plate 215. The residual water in the medicine bottle 212 drips into the water receiving tray 218 below through the bottle pushing device conveying mesh belt 214. The bottle pushing rod flipping reduction motor 222 is started to drive the bottle pushing rod 209 to rotate around the rotating axis. The three positions of the bottle pushing rod 209 when working are controlled by the three proximity switches in the proximity switch assembly 211 sensing the sensing block 210. A pair of optical fiber sensors 211 installed on both sides of the bottle pushing device conveyor belt 214 are used to determine whether there is a medicine bottle 212 at the landing point of the bottle pushing rod 209 on the bottle pushing device conveyor belt 214. If there is a medicine bottle 212, the rotation of the bottle pushing rod 209 is not allowed by the control system.

[0039] Due to certain requirements of the national GMP for equipment placed in clean workshops, the proximity switch assembly cover 220 is fixed to the outside of the proximity switch assembly 211 by bolts, the bottle push rod flip reduction motor cover 221 is fixed to the outside of the bottle push rod flip reduction motor 222 by bolts, and a secondary side cover 219 is fixed to the two sides of the bottle push assembly 2 by bolts, and those exposed electromechanical components that cannot be directly sprayed or wiped with disinfectants are isolated with stainless steel covers.

[0040] The bottle pushing device laminar flow rack assembly 3 is bolted to the bottom plate 201, covering the entire bottle pushing assembly 2 under the protection of its 100-level laminar flow, thereby ensuring the cleanliness requirements of the entire bottle pushing process. Moreover, through further laminar flow purging, the water remaining in the drug packaging container, the medicine bottle 212, during the bottle washing process can be removed and collected in the water receiving tray 218 under the conveyor mesh belt 214 of the bottle pushing device.

[0041] The peripheral decorative plate 401 in the tunnel oven decorative plate assembly 4 isolates the tunnel oven from the bottle pushing assembly 2, the lifting door slide 403 is fastened to the peripheral decorative plate 401 by bolts, and the two sides of the lifting door 402 are embedded in the lifting door slide 403, and the opening size of the bottle inlet of the tunnel oven is controlled by the lifting door 402. The entire assembly is used to isolate the high temperature of the tunnel oven from the influence of its peripheral equipment, but it also needs to ensure that the drug packaging containers can enter and exit the tunnel oven smoothly.

[0042] The method of using the utility model comprises the following steps:

[0043] S1: Start the hundred-level laminar flow device above the laminar flow rack assembly 3 of the bottle pushing device, firstly ensuring the environmental requirements when the equipment is working.

[0044] S2: Start the mesh belt drive motor 216, and transmit power to the bottle pushing device conveying mesh belt 214 through the mesh belt drive roller chain 217. The upper surface of the bottle pushing device conveying mesh belt 214 moves horizontally, providing power for the pharmaceutical packaging container, the medicine bottle 212 placed thereon, to enter the tunnel oven.

[0045] S3: The medicine packaging containers, medicine bottles 212, which are continuously conveyed from the bottle washing machine bottle outlet mesh belt assembly 1, arrive at the bottle pushing device conveyor mesh belt 214, and after being assisted by the bottle pushing device conveyor mesh belt 214 again, they enter the tunnel oven through the tunnel oven bottle inlet bridge plate 215 for sterilization. At the same time, in the bottle pushing device laminar flow rack assembly 3, further laminar flow blowing is performed to remove the water remaining in the medicine bottles 212 during the bottle washing process, and the water is collected in the water receiving tray 218 below the bottle pushing device conveyor mesh belt 214.

[0046] S4: Figure 8As shown, when the entire production batch is about to end, the last batch of medicine bottles 212 arrives on the bottle pushing device conveyor belt 214, and the optical fiber sensor 213 finds that there are no medicine bottles 212 at the rear of the bottle pushing device conveyor belt 214, and starts the servo motor 208 to drive the servo motor transmission gear 207 to rotate. Due to the gear meshing relationship, the ball screw transmission gear 206 rotates, driving the ball screw 205 to rotate, and moving the bottle pushing rod bracket 204 to the left limit position. Start the bottle pushing rod flip reduction motor 222 to drive the bottle pushing rod 209 to rotate around the rotating shaft, and stop when the induction block 210 installed at one end of the rotating shaft senses the lowest proximity switch in the proximity switch assembly 211.

[0047] S5: Fig. 9 As shown, the servo motor 208 is started to rotate in the reverse direction, and drives the servo motor transmission gear 207 to rotate in the reverse direction. Due to the gear meshing relationship, the ball screw transmission gear 206 rotates in the reverse direction, driving the ball screw 205 to rotate in the reverse direction, and moving the bottle push rod bracket 204 to the right extreme position.

[0048] S6: Fig.10 As shown, the servo motor 208 is started to drive the servo motor transmission gear 207 to rotate. Due to the meshing relationship of the gears, the ball screw transmission gear 206 rotates, driving the ball screw 205 to rotate, and moving the bottle push rod bracket 204 to the left limit position. Then, the bottle push rod flip reduction motor 222 is started to drive the bottle push rod 209 to rotate clockwise around the rotation axis, and the bottle push rod 209 stops when the induction block 210 installed at one end of the rotation axis senses the uppermost proximity switch in the proximity switch assembly 211.

[0049] S7: Fig.11 As shown, the servo motor 208 is started to rotate in the reverse direction, and drives the servo motor transmission gear 207 to rotate in the reverse direction. Due to the gear meshing relationship, the ball screw transmission gear 206 rotates in the reverse direction, driving the ball screw 205 to rotate in the reverse direction, and the bottle pushing rod bracket 204 is moved to the right extreme position. The bottle pushing rod 209 pushes the pharmaceutical packaging container, the medicine bottle 212 placed on the bottle pushing device conveying mesh belt 214 through the tunnel oven bottle inlet bridge plate 215 and enters the tunnel oven.

[0050] S7: Fig.12As shown, the servo motor 208 is started to drive the servo motor transmission gear 207 to rotate. Due to the meshing relationship of the gears, the ball screw transmission gear 206 rotates, driving the ball screw 205 to rotate, and the bottle push rod bracket 204 is moved to the middle position of the bottle push assembly 2. Then, the bottle push rod flip reduction motor 222 is started to drive the bottle push rod 209 to rotate counterclockwise around the rotation axis. When the induction block 210 installed at one end of the rotation axis senses a proximity switch in the middle of the proximity switch assembly 211, it stops and waits for the next batch of medicine packaging containers sent from the bottle washing machine bottle discharging mesh belt assembly 1 to pass.

[0051] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
