Description

Technical Field

[0001] The utility model belongs to the technical field of glass tube production, and particularly relates to a glass tube rejection collection device. Background Art

[0002] In the prior art, a port detection device is usually arranged at the end of a glass tube project. The defective glass tubes (hereinafter simply referred to as: glass tube rejections) detected by the port detection device are discarded after falling through the subsequent rejection device. The main types of defects of the glass tube rejections detected by the end port detection device are: cracks, length defects, square mouths, bottom sealing defects, punching defects, etc. Most of these defective products are only produced during the processes of bottom sealing, punching or precision cutting of the round mouth, and all the defects are located at both ends of the glass tube, and these parts are originally to be discarded during bottle making. Therefore, these defective products can be collected for use in bottle making equipment or sold as grade B products.

[0003] In addition, during the production process, once the automatic packaging equipment breaks down and stops, the glass tubes on the production line will fall into the broken glass tank and be discarded, resulting in high production costs and low yield. A glass tube rejection collection device is needed to collect the above-mentioned defective products and add them after the equipment returns to normal or use them for other purposes. Summary of the Invention

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] As Figure 1 , Figure 5 shown, the present invention discloses a glass tube picking and collecting device, which includes a buffer device 1, an intermittent blanking device 2, a transmission device 3, a tube pushing device 4 and a collecting rack 5. The transmission device 3 includes a receiving block 3.1, a transmission motor 3.2, a support frame 3.3, and a transmission device 3.4. The buffer device 1, the intermittent blanking device 2, and the tube pushing device 4 are arranged on the support frame 3.3. The transmission device 3.4 can adopt a chain or a synchronous belt. The receiving block 3.1 is fixedly arranged on the transmission device 3.4. The transmission motor 3.2 is arranged on the support frame 3.3. The output shaft of the transmission motor 3.2 is connected to the transmission device 3.4. When the transmission motor 3.2 rotates, the transmission device 3.4 drives the receiving block 3.1 to move. Preferably, the transmission device 3.4 adopts chain drive. The chain is supported by a special guide rail. A V-shaped receiving block 3.1 is arranged on the chain to receive the glass tube picking 6. The transmission speed is adjustable. The chain can also be provided with a floating tensioning device.

[0026] As Figure 2 shown, the buffer device 1 includes a lower slideway 1.1 and an upper slideway 1.2. The upper slideway 1.2 and the lower slideway 1.1 form a buffer slideway. The width of the buffer slideway can be adjusted according to the product specifications of the glass tube picking 6, so that the glass tube picking 6 falls into the buffer slideway and is arranged vertically in a single row and accumulates upward, avoiding collision and scratching of the glass tube picking 6 and thus affecting the product quality. The part of the buffer slideway in contact with the glass tube adopts a heat-resistant non-metallic material, such as nylon. Preferably, the length of the buffer slideway is selected to be 300 - 600 millimeters, and 12 - 50 glass tube pickings can be stored. The buffer slideway is provided with a speed reduction mechanism 1.3, and the speed reduction mechanism 1.3 adopts a spring.

[0027] As Figure 3 shown, the intermittent blanking device 2 is below the buffer device 1. The intermittent blanking device 2 includes a blocking air cylinder 2.1, a blocking air cylinder solenoid valve 2.2, a tube dropping air cylinder 2.3, a tube dropping air cylinder solenoid valve 2.4, a blocking air cylinder baffle 2.5, and a tube dropping air cylinder baffle 2.6. The blocking air cylinder 2.1 is electrically connected to the blocking air cylinder solenoid valve 2.2 and is used to control the advancement and retraction of the blocking air cylinder baffle 2.5. The tube dropping air cylinder 2.3 is electrically connected to the tube dropping air cylinder solenoid valve 2.4 and is used to control the advancement and retraction of the tube dropping air cylinder baffle 2.6. The blocking air cylinder baffle 2.5 is arranged above the tube dropping air cylinder baffle 2.6.

[0028] As Figure 4As shown in the figure, the process of the buffer device and the interval blanking device cooperating in the working state is as follows: The blocking cylinder 2.1 and the downpipe cylinder 2.3 drive the blocking cylinder baffle 2.5 and the downpipe cylinder baffle 2.6 to move forward respectively. The glass tube rejecting tube 6 falls onto the blocking cylinder baffle 2.5 through the buffer slideway. The blocking cylinder baffle 2.5 retreats, and the single glass tube rejecting tube 6 falls onto the downpipe cylinder baffle 2.6. The blocking cylinder baffle 2.5 advances to block the falling of the upper glass tube rejecting tube 6. The downpipe cylinder baffle 2.6 retreats, and the single glass tube rejecting tube 6 is released and falls onto the receiving block 3.1 of the transmission device 3.

[0029] As Figure 6 shown in the figure, the tube-pushing device 4 includes a tube-pushing motor 4.1, a tube-pushing fork 4.2, a tube-pushing shaft 4.4, and a tube-pushing detection switch 4.3. The output shaft of the tube-pushing motor 4.1 is connected to the tube-pushing shaft 4.4, and the tube-pushing fork is arranged on the tube-pushing shaft. When the tube-pushing detection switch 4.3 detects that the tube-rejecting tube 6 is in place for transmission, the tube-pushing motor 4.1 drives the tube-pushing shaft 4.4 to rotate, and then the tube-pushing fork 4.2 rotates. Preferably, the tube-pushing fork rotates 60 degrees, and then the glass tube rejecting tube 6 is pushed from the conveyor belt into the collection rack 5. Preferably, the tube-pushing motor 4.1 is a servo motor.

[0030] As Figure 7 shown in the figure, the collection rack 5 is arranged on one side of the tube-pushing device 4. The collection rack 5 is a sloped collection rack 5 for collecting the glass tube rejecting tubes 6. After reaching a certain quantity, manual operations can be carried out for the next steps of collection, packaging, and storage.

[0031] According to the above settings, a corresponding control system can also be added as needed to achieve servo linkage, PLC control, and a human-machine interface with convenient and simple touch-screen operation input. This makes the controllability of the device stronger.

[0032] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
