長を有するものである。 Detailed Description of the Invention (Field of Industrial Application) The present invention relates to continuous molding of can caps, in which the molding and closing of caps used for cans such as cans and pull-top cans are performed continuously in the same process. This relates to a lid method. (Prior art) Conventionally, when forming a cap on a can body such as a can or a pull-top can (hereinafter referred to as a "can body"), molding the cap body and closing the can body were performed in separate work processes. Therefore, the workability was very poor, and since each device was constructed separately, it had the disadvantage of being large and expensive. (Purpose) The present invention enables the molding of the cap body and the closing of the can body to be performed continuously in the same process, significantly improving work efficiency, and at the same time, integrating the device.
Moreover, it is made smaller and can be supplied at low cost. (Structure) In order to achieve the above object, the present invention transports a band-shaped plastic film to a predetermined pitch, and forms a cap recess with the recess on the upper side using a film molding means that sequentially forms recesses of a predetermined shape. Next, the periphery of the cap recess is punched out using a trimming means to form individual caps, and the caps are transported in a substantially horizontal state to a predetermined pitch by a transport conveyor with the recess facing upward, and from above the transport conveyor, The can body is tilted downward in the same direction as the traveling direction of the conveyor, and the can body is advanced in synchronization with the conveyance of the cap, so that the bottom tip of the can body and the inside edge of the tip of the cap are engaged. The bottom of the can and the cap are then fitted together by pressing from above the can. This will be explained in detail below based on examples. 1 to 6 show an example of an apparatus for carrying out the present invention, in which 1 is a strip-shaped film transporting apparatus. The belt-shaped film transfer device 1 is a well-known device, and includes two endless chains 3, 3' installed on a machine frame 2, and the endless chains 3, 3'.
The endless chain 3, 3' consists of a large number of film holding claws (not shown) attached to the endless chain 3, 3'.
sprocket 4 so that it is transferred at every predetermined pitch.
It is set up on. Reference numeral 5 denotes a well-known vertically movable molding chamber disposed at a predetermined position of the film strip transfer device 1. The upper chamber 5a is fixed, and the movable lower chamber 5b has a film formed of a hot plate inside. It is equipped with a preheating device 5c and a pressure vacuum forming mold 5d. Reference numeral 6 denotes a well-known trimming chamber disposed at a predetermined position of the film strip transfer device 1 , with a female punching die 6b inside the movable lower chamber 6a, and a fixed trimming chamber inside the upper chamber 6c. It is equipped with a male punching die 6d. Reference numeral 7 denotes a perforation/cooling chamber disposed at a predetermined position of the film strip transfer device 1. The fixed upper chamber 7a is provided with a perforation needle 7b, and the movable lower chamber 7c is provided with cooling water, gas, etc. cooling element 7
It is equipped with d. Note that the holes and the cooling chamber 7 may not be provided if necessary. Reference numeral 8 denotes a cap conveyor conveyor provided in the machine frame 2 below the trimming chamber 6 , and is an endless conveyor in which feed claws 8a are attached at predetermined pitches to push the caps a punched out in the trimming chamber 6 . It consists of a chain 8b and a sprocket 8c for driving the endless chain 8b. Reference numeral 9 denotes a can discharge gutter, which is disposed at the top of the discharge end side of the cap conveyor 8 in a forward-slanted state. Reference numeral 10 denotes a can stop/release device disposed at the tip side of the canned can delivery gutter,
As shown in Figures 1 and 3, it consists of a first stopper 10a that stops and releases the first can b 1 and a second stopper 10b that stops and releases the next can b 2. When 10a releases the first can b 1 , the second stopper 10 b stops the next can b 2 , and the first stopper 10 a
When the first canned can b1 is stopped, the second stopper 10b releases the stop of the next canned can b2 , and the canned cans b are sequentially carried out starting from the first canned can. In addition, the canned can stop and release device 10
The timing of operation of the first and second stoppers 10a and 10b in 1 is synchronized with the timing of conveyance of the cap body a. The first and second stoppers 10a and 10b may be driven via an appropriate drive mechanism (not shown), such as a well-known electromagnetic valve, other electrically actuated drive mechanism, or other mechanical drive mechanism. The movement direction may be either vertical, horizontal, horizontal, etc., as shown in FIGS. 6a and 6b. Reference numeral 11 denotes a conveyor for conveying canned cans, which conveys canned cans b to the canned can conveying gutter 9 .
It is for carrying in. Reference numeral 12 denotes a cap pressing member such as a sponge roller, which is disposed at the upper part of the exit side of the canned can delivery gutter, and its installation height can be adjusted as appropriate depending on the size of the canned can b. There is. 13 is a discharge chute, 14
15 is a discharge conveyor, 15 is a guide roller, 16 is a winding device for winding up the strip film F' after removing the cap body a, F is a strip film, and C is a plurality of strip films F arranged in parallel (in this embodiment). are concave portions for caps formed in four rows in the horizontal direction. The film strip F , which is intermittently transferred at predetermined pitches by the film strip transfer device 1 , is heated and softened by the film preheating device 5c of the forming chamber 5, and is then molded into a plurality of parallel concave portions C for caps by the compressed air vacuum mold 5d. A small hole is made in the concave portion C for the cap in the cooling chamber 7 , and the cap is cooled by the cooling element 7d, and then the cap is formed in the next trimming chamber 6 by punching dies 6b and 6d. The concave portion C is punched out. The punched cap body a falls from the punching female mold 6b onto the cap body transport conveyor 8 below, and is transferred to the feed claw 8a.
The paper is transported toward the discharge side at predetermined pitches. In such a case, the first of the many canned cans b waiting in a forward-leaning state on the canned can carry-out gutter 9 which is arranged in a forward-leaning state at the upper part of the discharge end side of the cap body conveyor 8. The can b 1 is moved by the first and second stoppers 1 of the can stop and release device 10 in synchronization with the conveyance timing of the cap body conveyor 8 .
0a and 10b, the bottom end portion b' engages with the inner end edge a' of the cap body that slides on the canned can delivery gutter 9 and is located below as shown in the third figure;
While moving together with the cap body a, the can b 1 is pressed from above by a cap body pressing member 12 , and the entire bottom circumference of the can b 1 is fitted into the cap body a, and the can b 1 is carried out to the discharge conveyor 14 as shown in the first figure. It is something that will be done. The band-shaped film F' after the cap body a has been punched out is wound up by the winding device 16 when gripping claws (not shown) gripping both side edges are released. (Effects) According to the present invention, the molding of the cap body and the closing of the can body can be performed continuously in an integrated process, and work efficiency can be significantly improved. Since the can body is fitted to the cap body, the device can be made simpler and smaller, and the cost can be lowered, compared to the method in which the cap body is fitted to the can body. It has various features such as being able to greatly reduce the area and work area and being easily implemented in a small area.
