A filter discharge device provided in an embodiment of the present application will now be described.

Examples:

the embodiment provides a filter unloading device, which is based on the illustration in fig. 1, 3 and 7 and comprises a transferring device 1, a bearing device 2 and a reject unloading device 3. The carrier device 2 is provided with a reject path 201 and a reject path 202. The transfer device 1 is provided with material taking units 101 which are in one-to-one correspondence with the filter grooves 200 on the mold 100. In this embodiment, twenty-four filter tanks 200 are linearly arranged on the mold 100, and twenty-four filters can be simultaneously loaded, and correspondingly, twenty-four sets of material taking units 101 are linearly arranged on the transfer device 1. Each material taking unit 101 is provided with an independent driving device, and all the independent driving devices are connected with a detection device used in a detection procedure in the filter assembly device in a signal manner, wherein the detection device can be automatically controlled through an electric signal or manually controlled. The take-out unit 101 reciprocates between the mold 100 and the accept path 201. The reject unloading device 3 corresponds to the filter tank 200 on the mold 100, and the reject unloading device 3 is disposed toward the reject path 202.

After the filter is assembled and detected on the filter assembling device, the turntable of the filter assembling device transfers the mold 100 with the filter to the filter unloading device, and simultaneously, the signal of the pre-detection procedure is transmitted to the independent driving device. When the device is used, twenty-four independent driving devices selectively act according to signals of a pre-working procedure, namely, only the independent driving devices corresponding to qualified products act, the material taking unit 101 is driven to grasp qualified filters, the independent driving devices corresponding to unqualified products do not act, and the unqualified filters are left on the clamping fixture 100. When all the qualified products are removed, the material taking unit 101 moves from the mold 100 to the position of the qualified product channel 201, the independent driving device acts again, and the filter is separated from the material taking unit 101 and falls into the qualified product channel 201. For the reject remaining on the mold 100, the reject unloading apparatus 3 transfers it to the reject path 202. When all filters are unloaded, the take-out unit 101 moves to reset above the mold 100 to accept the next batch of filters. The filter discharging device integrates the separation work of the unqualified products and the qualified products into the discharging device, and does not need to set an independent separation process, so that the flow is simplified, and the production efficiency is improved.

Further, based on the figures 1 to 4, the transfer device 1 comprises a first frame 102 and a transfer mechanism 103. The first frame 102 is a vertically placed rectangular frame structure, and a transverse transfer sliding rail 107 and a transfer cylinder 108 are arranged on the top of the top plate of the first frame 102. The extending directions of the lateral transfer slide rail 107 and the transfer cylinder 108 are perpendicular to the arrangement direction of the material taking units 101. The transfer mechanism 103 includes a mount 104, a lifting cylinder 105, and a lifting bracket 106. The lifting cylinder 105 is connected with the mounting base 104, and the lifting bracket 106 is positioned at the bottom of the mounting base 104 and is connected with the output end of the lifting cylinder 105. Twenty-four take-out units 101 are arranged on a lifting carriage 106. The mounting base 104 is slidably disposed on the transverse transfer slide rail 107, and an output end of the transfer cylinder 108 is connected to the mounting base 104.

When the mold 100 with the filter is transferred to the filter unloading device, the transfer mechanism 103 is located directly above the mold 100. First, the lifting cylinder 105 drives the lifting bracket 106 to descend, so that all the material taking units 101 approach the corresponding filters. According to the signal of the pre-detection process, only the independent driving device corresponding to the qualified product acts to drive the material taking unit 101 to grasp the qualified filter, and the unqualified filter is left on the mold 100. After the qualified products are grabbed, the lifting cylinder 105 drives the lifting bracket 106 to lift up, and the qualified filter is lifted up. Subsequently, the transfer mechanism 103 is driven by the transfer cylinder 108 to slide along the transverse transfer slide rail 107, so that the material taking unit 101 moves to a position right above the qualified product channel 201. The lifting bracket 106 is driven to descend again through the lifting cylinder 105, the material taking unit 101 is driven to act through the independent driving device, and the filter falls on the qualified product channel 201. Finally, the lifting cylinder 105 is lifted and reset, the independent driving device is reset, and the transfer cylinder 108 drives the transfer mechanism 103 to reversely slide and reset along the transverse transfer sliding rail 107.

Preferably, since twenty four groups of material taking units 101 are long in arrangement length, two groups of transfer mechanisms 103 may be provided to ensure stability of the transfer mechanisms 103, and twelve groups of material taking units 101 are provided for each group of transfer mechanisms 103. Correspondingly, a transfer slide plate 127 is slidably arranged on the transverse transfer slide rail 107, and the mounting seats 104 of the two groups of transfer mechanisms 103 are respectively arranged on the transfer slide plate 127. The output end of the transfer cylinder 108 is connected to a transfer slide 127 for indirect connection to the mount 104. The output end of the transfer cylinder 108 drives the transfer mechanism 103 to move by driving the transfer slide 127 to slide along the transverse transfer slide rail 107. Of course, in other embodiments, the number of transfer mechanisms 103 may be adjusted according to the actual situation. Meanwhile, in order to ensure the accuracy of the position when the output end of the transfer cylinder 108 extends to the distal end, a second stopper 126 opposite to the transfer slide 127 is provided at the top of the top plate of the first frame 102. The second limiting member 126 may be a limiting block or an adjustable limiting screw. When the output end of the transfer cylinder 108 extends to the distal end, the transfer slide plate 127 abuts against the second limiting member 126, so as to ensure the accuracy of the extending distance.

Preferably, based on the fig. 3 and 4, the mounting base 104 is vertically provided with a first linear bearing 121, and the top of the lifting bracket 106 is provided with a first lifting shaft 122 slidably penetrating the first linear bearing 121. When the lifting cylinder 105 drives the lifting bracket 106 to lift, the first lifting shaft 122 slides along the first linear bearing 121. The first linear bearing 121 and the first elevating shaft 122 serve as guides. Meanwhile, in order to increase the stability of lifting, four first linear bearings 121 are provided around the lifting cylinder 105, and four first lifting shafts 122 respectively slidably provided at the four first linear bearings 121 are provided at the top of the lifting bracket 106. In other embodiments, the number of the first linear bearings 121 and the first elevating shafts 122 may be adjusted according to actual situations.

Preferably, a material taking limiting plate 123 is mounted on the top of the first lifting shaft 122, and a first limiting member 124 located on the top of the lifting cylinder 105 is disposed on the material taking limiting plate 123. The first limiting member 124 may be a limiting block or an adjustable limiting screw. When the output end of the lifting cylinder 105 extends downwards and the material taking unit 101 moves to a proper position above the material, the first limiting piece 124 abuts against the top of the lifting cylinder 105, so that the accuracy of the extending distance of the output end of the lifting cylinder 105 is ensured.

Further, as shown in fig. 3 to 5, the lifting bracket 106 is provided with a mounting plate 109 and a reject plate 110 located at the bottom of the mounting plate 109, and the mounting plate 109 and the reject plate 110 are connected to each other by a riser 125. The independent driving device is a vertical cylinder 111, the vertical cylinder 111 is mounted on the top of the mounting plate 109, and the output end of the vertical cylinder 111 extends to the bottom of the mounting plate 109. The material taking unit 101 comprises a material taking rod 112 and a vertical material returning barrel 113, wherein the vertical material returning barrel 113 is arranged at the bottom end of the material returning plate 110, and the material taking rod 112 vertically slides and penetrates through the vertical material returning barrel 113. The top end of the take-off rod 112 is connected to the output end of the vertical cylinder 111. The bottom end of the take-off lever 112 is provided with a clamping portion 114. The vertical cylinder 111 drives the material taking rod 112 to slide along the vertical material returning barrel 113, so that the clamping part 114 can extend or retract to the bottom end of the vertical material returning barrel 113. The clamping portion 114 is located above the mold 100 and the accept path 201.

The engaging portion 114 is for engaging with the filter. When the filter needs to be grabbed, the vertical cylinder 111 acts, the output shaft of the vertical cylinder extends and drives the clamping part 114 at the bottom of the material taking rod 112 to extend out of the bottom end of the vertical material returning cylinder 113, and the clamping part 114 is clamped with the filter. At this time, the lifting cylinder 105 drives the lifting bracket 106 to lift, and the filter can lift along with the clamping portion 114. When the filter needs to be put down, the vertical cylinder 111 acts, the output shaft thereof retracts and drives the clamping part 114 at the bottom of the material taking rod 112 to retract into the vertical material returning barrel 113, and the filter can fall off under the dislocation butt action of the vertical material returning barrel 113 and the clamping part 114.

Further, based on the illustration of fig. 5, a first groove 115 is formed at the top of the material returning plate 110, and a vertical material returning cylinder 113 penetrates the material returning plate 110 from the bottom wall of the first groove 115. The top cover of the material returning plate 110 is connected with a pressing plate 117, a second groove 118 is formed in the side wall of the pressing plate 117 facing the first groove 115, and the material taking rod 112 penetrates through the pressing plate 117 and the second groove 118 from the top and finally penetrates into the vertical material returning barrel 113. The top outer side wall of the vertical withdrawal cylinder 113 is provided with a first catch 116 which is provided on the bottom wall of the first recess 115. The stripper plate 110 is bolted or riveted to the hold-down plate 117. An elastic member 119 is sandwiched between the first card edge 116 and the bottom wall of the second groove 118. The elastic member 119 is preferably a spring that is sleeved on the outside of the take-off lever 112. The spring presses the first catch 116 against the bottom wall of the first recess 115 to keep the vertical withdrawal chimney 113 stable. In other embodiments, the elastic member 119 may also be an elastic sleeve or a spring plate, etc.

In use, the arrangement height of the filters on the mold 100 may fluctuate, and when the vertical cylinder 111 drives the lifting bracket 106 to move downward, the bottom end of the vertical withdrawal cylinder 113 may collide with a part of the filters. The elastic member 119 can play a certain role in buffering and enable the vertical withdrawal cylinder 113 to generate a certain vertical movement allowance, so that the vertical withdrawal cylinder 113 cannot crush the filter.

Preferably, based on the illustration of fig. 5, the top outer sidewall of the take-off bar 112 is provided with a second clamping edge 128 that movably abuts the top of the compression plate 117. When the vertical cylinder 111 drives the material taking rod 112 to move downwards to the clamping part 114 to be clamped with the filter, the second clamping edge 128 is abutted with the top of the compression plate 117, so that the material taking rod 112 is limited to move downwards continuously, and the accuracy of the moving distance of the material taking rod 112 is ensured.

In this embodiment, the filter is a liquid medicine filter. Based on the fig. 4, 6 and 8, the top of the liquid medicine filter is provided with a columnar protrusion, the clamping part 114 is a hollow clamping ring, and the inner side of the hollow clamping ring is in interference clamping with the outer side wall of the columnar protrusion at the top of the liquid medicine filter. Two elastic notches 120 are provided around the bottom of the hollow clasp to elastically clamp the medical fluid filter. Of course, in other embodiments, three or four or the like may be provided around the resilient notch 120 of the bottom of the hollow clasp.

In other embodiments, the filter may also be an air filter. Based on the figures 4, 6 and 9, the top of the air filter is provided with a groove structure, the clamping part 114 is a hollow clamping ring, and the outer side of the hollow clamping ring is in interference clamping with the inner side wall of the groove structure at the top of the air filter.

Twenty-four ejector pins 303 are arranged at the top of the ejector assembly, and the twenty-four ejector pins 303 are in one-to-one correspondence with the bottoms of the twenty-four filter grooves 200 on the mold 100. The blowing device comprises an air outlet pipe 305, and the air outlet pipe 305 is connected with an external air source. The air outlet pipes 305 are provided with twenty-four air outlet ends 304 corresponding to the tops of the filter grooves 200 on the mold 100 one by one, and the air outlet ends 304 are arranged towards the reject channels 202. The air blown from the external air source flows along the air outlet pipe 305 and is blown from the air outlet end 304 toward the top of the filter tank 200.

In use, when the good is removed by the transfer device 1, the jacking cylinder 302 drives the jacking assembly to move upwards, and the jacking rod 303 jacks up the defective product left on the mold 100 from the bottom, so that the defective product is separated from the filter tank 200. At this time, the external air source is activated, and air is blown out from the air outlet end 304, and the reject is blown down to the reject path 202. Because the filter tank 200 in which the good product is located on the mold 100 is empty, all twenty-four ejector pins 303 can be raised simultaneously, and the separate transfer of the good product and the bad product is not affected.

Preferably, to ensure that the reject is accurately dropped into the reject channel 202 when blown off, the inlet of the reject channel 202 is located at the bottom of the edge of the mould 100. Meanwhile, the two ends of the air outlet pipe 305 are fixed on the bearing device 2, but are not directly connected with the second rack 301 or the jacking component, so that the relative position between the air outlet pipe 305 and the reject channel 202 is ensured. The outlet pipe 305 does not move with the jacking assembly, ensuring stability when connected to an external air source.

The support plate 306 is bolted or riveted to the fixing plate 307 to clamp the ejector pin 303.

Preferably, based on fig. 7 and 11, the second rack 301 is vertically provided with a second linear bearing 310 at the top, and a second lifting shaft 311 slidably installed through the second linear bearing 310 is provided at the bottom of the support plate 306. The second linear bearing 310 and the second elevating shaft 311 may increase stability of the ejector assembly while elevating. Meanwhile, two or more groups of second linear bearings 310 and second lifting shafts 311 may be provided, and the groups of second linear bearings 310 and second lifting shafts 311 are symmetrically provided at both sides of the output end of the lifting cylinder 302, so as to ensure the balance of the material lifting assembly.
