- FIG. 8 is an elevational view of a capped cup illustrating the manner of removing the cap when desired.
- the embodiment illustrated comprises a frame structure 11, including legs 12, 13, I4 and and a bottom platform 16.
- An elevator mechanism is mounted in the frame structure and it comprises a vertical conventional air cylinder 17 secured to a fixed frame member 18 and having a vertically reciprocating rod 19 at the top.
- the air cylinder 17 is operated by conventional means, including air lines 20 and 21 con nected to an air control member 22.
- the upper end of the rod 19 is pivotally connected to a bracket 23 by a pin 24.
- the bracket 23 is secured by bolts 25 to the bottom of a vertically movable lower shelf 26.
- An upper shelf 27, vertically spaced above the lower shelf 26, is connected to the lower shelf by means of tubular stanchions 28.
- Rods 29 pass through the stanchions 28 and are secured at their lower ends to the frame member 18. The upper ends of the rods extend above the upper shelf 27 and are secured to an upper frame member 30.
- An elevator platform 31 is disposed above the frame member and it is rigidly connected to the upper shelf 27 by means of rods 32 which pass through apertures 33 of the frame member 30. By these means, actuation of the air cylinder 17 causes the platform 31 to move vertically.
- the platform 31 supports a group of cups 34 to be capped in a conventional portable tray 35. These cups are held in alignment with a bank of capping units hereinafter described, by disposing the tray against abutments 36 and 37 in right angular planes and permitting the bottoms of the cups to rest in fixed pockets 37A on the platform 31.
- the capping assembly 38 Above the platform 31 there is mounted on the frame structure the capping assembly 38 on brackets 39, 39 connected by bolts 40.
- the capping assembly comprises a plate 41 subdivided by orthogonal grooves 42 and 43 into smaller areas. In the grooves 42 and 43, knife blades 48 are set having scalloped cutting edge 49 at the bottom. Each subdivided area of the plate 41 has an aperture 44 in which there is mounted a wiper ring 45.
- a sealing iron 47 comprises a circular block 50 having an annular downwardly extending edge 51 adapted to register with the rim 52 of a cup to be capped. Such a sealing iron is slidably mounted in each wiper ring 45.
- the block 50 has an internal annular channel 53 which communicates on one side with an inlet hose 54 and on the other side with an outlet hose 55 through a cover plate 56. Threaded 57 and 58 of the cover plate engage hose nipples 59 and 60.
- the hoses 54 and 55 are adapted to effect circulation of a heat exchange liquid 61 through the channel 53 at a given temperature.
- the block 50 is mounted on the bottom of a vertical shaft 62 by means of a screw 63.
- the upper end of the shaft 62 is slidably mounted on a bracket 64 connected to a frame member 65.
- the shaft 62 is biased to a downward position by means of a coil spring 66 disposed on the shaft between the bracket 64 and the top of the cover plate 56.
- a flange 67 at the upper end of the shaft 62 limits the: downward movement of the shaft.
- the inlet hoses 54 of all the irons 47 are connected to a common inlet header or plenum chamber 68 and the outlet hoses 55 are likewise connected to a separate common outlet header or plenum chamber 69.
- the headers 68 and 69 function to equalize the flow of the heat exchange liquid to and from the irons 47.
- An expansion tank 70 is mounted above the inlet header 68 and it is connected to the inlet header by a T-connector 71.
- a tank 72 for the heat exchange liquid is mounted on brackets 73 and 74 to the frame structure and a pipe 75 connects the outlet of the tank with the header 68.
- a hydraulic pump 76 is also mounted on the frame structure by any conventional means and its outlet 77 is connected to the inlet 78 of the tank 72 by a pipe 79. The inlet of the pump 76 is connected to the header 69 by means of a pipe 80.
- a conventional electrical heater 81 is disposed inside the tank 72 to maintain the temperature of the heat exchange liquid at a desired level.
- the hot liquid is thus circulated by the pump 76 from the tank 72 to the header 68 through the channels 53 and returns through the header 69 and pipe to the pump 76.
- This provides a uniform temperature throughout all the sealing units which would be difficult, if at all possible, to provide by other means such as direct electrical heat means.
- the device is used by placing the tray 34 of cups 33 on the platform 31 against the alignment abutments 35 and 36.
- a heat scalable sheet of material 82 of any conventional type is then placed on top of the cups 33.
- the air cylinder 17 is then actuated to raise the elevator platform 31 to cause the sheet 81 to contact the edges 51 of the irons 47 which fuses the sheet to the rims of the cups.
- the elevator is then lowered and the tray of capped cups removed.
- the wiper rings 45 function to fold down the outer marginal edges of the individual sections around the rims 52 of the cups as a sanitary measure. See FIGS. 7 and 8..
