SUMMARY OF THE INVENTION
The present invention relates to an automatic tape-applying device which is employed to carry out the adherence of sealing tapes, especially along the edges of a carton, for sealing purposes. ~ short brush means moves repaatedly in a horizontal direction and ls operated by an alr-actuated cylinder to reciprocate in a pre-set distance so that a pre-located tape, half of which is already attached along one edge of the surface o~ a positioned carton (the othex half extending over the edge), is first neatly fixed at the two corners thereoE, and then smoothly adhered along the edges by an elongated brush moving repeatedly up and down in a vertical direction.
In a conventional carton-sealing machine, a carton can only be automatically sealed along the central portion of the top and bottom side by elongated tapes, leaving the edges and corners to be sealed manually. This results in a waste of time and labour which is required to carry out the sealing operation. In consideration of security against smuggling, or illegal delivery, many countries require transporation cartons to be tightly sealed. For this reason a totally automatic carton sealing device now becomes more useful than ever before.
Furthermore, a carton-sealing device of the prior art adopted a disk-shaped rotary brush means to adhere elongate tapes along the edges of a carton. However, due to the relative movement oE the carton and rotating brush means, wrinkles are oEten produced in the seallng tapes.
Therefore, the primary object of the present invention is to provide an automatic tape-applying device which is ' ~2~7~
particularly sulted to fix elongated tapes along the edges of a carton by means of a short brush~ disposed at a proper position from -the tape applying means and repeat0dly moved in a horizontal direction by an air-actuated cyllnder, to smoothly and neatly fix both ends of the elongated tape at the corners thereo*.
One further object of the present invention is to provide an automatic tape-applying device which is partlcularly suited to fix elongated tapes along the edges of a carton by means of an ~longate bxush disposed at a proper distance beside said short brush and repeatedly moved up and down in a vertical direction when the carton to be sealed is transmitted in front thereof so that the tape can be totally and smoothly adhered along the edge of the carton.
Accordingly, the invention herein comprises an automatic tape-fixing device for a carton sealing machine, having means for applying tapes along the edges of a carton, and being equipped with short and elongated brushes disposed in line and at adjustable distance from each other and along the upper and lower sides of upper and lower frames in a symmetric manner, adapted to apply tapes to four edges simultaneously of a forwardly movi.ng carton, and said short and elongated brushes operated by air-actuated cylinders being disposed at a proper distance next from a tape applying means, said tape-Eixing device comprising: a short brush having a split-clamp end for securing the same to a chain member driven by a pair of sprockets each having a gear located thereunder which engages with a rack 2l[~
disposed in front of an air-actuated cylinder so that said short brush can be ac~uated to repeatedly move back and for-th; an elon-gated brush being disposed in line and at proper distance, next to said short brush, and provided with an extended pi.n at each end thereof which is in contacta~ssociation with a knife-shaped cam protrusion for confinedly guiding the movement of said elon-gated brush by means of the contour of said cam protrusion, and said elongated brush being connected to a brush actuating base by an elongate hinge bar which having a pair of twisting springs located at each end thereof to change the operating position of said brush actuating base, and an air-actuated cylinder being secured to the bottom of the base; the above-mentioned components being s-~ructure so that the components are disposed in pairs on an upper and lower frame, four worm rods being disposed between the frames and secured to said upper frame with their top ends by four mounting seats, and at the bottom ends thereof are pro-vided with sprockets, connected to each other by a chain member so that said four worm rods can be simultaneously actuated to rotate by a motor located at the bottom end of one worm rod so to effect adjustment of the dlstance between said upper and lower frames, the distance between conveyor belts disposed on said upper and-lower frames being changed by moving one of said conveyor belts to the left or right by means of a worm rod horizontally disposed with one end thereof secured to a mounting seat and the other end attached to a turniny knob so that the conveyor belts can be adjusted for cartons of different size.

DETAILED DESCRIPTION
.
As shown in Figure l, the present invention is structurally in association with an upper frame 30, a lower frame l0, both equipped wi-th conveyor belts ll to transmit a carton to a tape applying means 12, located in symmetry at both , sides of said upper and lower frame 30and 10, respect.ively, where tapes are applied automatlcally along the symmetrlc cdyes of said carton, and the par~ially ~ixed -tapes are Eirst repeateclly brushed over by means o:E a pair of short brushes 13 i.n a hori~ontal direction at both corners of the edges so as to neatly adhere the tapes, then elongated brushes 43, operated by air-actuated cylinders 31, are moved up and down repeatedly in a vertlcal direction to make the rest of said elongated tapes, disposed along the opposing edges, adhere to the surface of said carton when said carton is transmitted to a selected position, so tha-t the sealing o sald carton is achieved automatically without the use of manual labour.
Referring to Figure 7, the flow chart shows that a carton S, transmitted by conveyor belts 11 to a symmetrically located tape applying means 12 in an up and down manner, is attached with sealing tapes along the upper and lower edges.
Then short brushes 13 are actuated by cylinders 15 to brush over the fixed tapes at the corners to neatly adhere the tapes, the reversely moving brush can further flatten the tapes once again, then elongated brushes 43 are moved up and down to brush over the rest of said tapes S2 to complete the automatic sealing process.
Referrlng to Figure 1 and Figure 2, the devlce is provided with a short brush 13 disposed at a proper position near the end of said tape applying means 12, which is able to repeatedly move in a synchronous manner within a pre-set range.
The short brush 13 has a split clamp end 131 which is used to , fix said brush to a chain 132 mounted between a pa:Lr o.E
sprockets 141 and driving gear 19 which engages Witll a rack 151 attached to the front of cylind~r 15, which is controlled to move in dual direc-tions and within a selected range, so -that said shor-t hrush 13 can effect a repeated motlon in pre-set distance. This permits smooth attachment of the tape ends Sl at the corners of sald carton S in a proper order, terminating the first step of the tape-fixing process, as shown in Figure 3.
As further shown in Flgures 1 and 4, said carton S is continuously moved, through the above-mentioned process, by means of a conveyor belt 11 to elongated brushes 43, disposed in juxtaposition to said short brushes 13 but at a proper distance from each other, which are moved repeatedly in a vertic~l direction to flatly adhere the tapes to the surface of said carton lengthwisely along the edges. At bo-th ends of a hinge bar 41, there ar~ at~ached twisting springs 42, and the hinge bar 41 i6 mounted lengthwisely along the brush actuating base 40, the bottom of which is connected to the front end of cylinder 31 by a push bar 311 so that the elonga-ted brush 43 can be repeatedly moved up and down, by sald cylinder, to smoothly brush over the elongated tape portion S2 -to complete the sealing of carton S. There is an extended pin member 431 dlsposed ak each end oE brush 43 and is ~onfinedly guided in a knife-shaped protru~lon 401 on a stop plate of a frame 33 so that extended pin member 431 can be slidably moved along the external contour of protrusion 401. Cylinder 31 and said frame 33 are joined together by means of a support structure 32 with ~l~8~
push bar 311 goin~ thxough the bottom of fr~me 33 and integxcllly connected to brush actuating base 40. As shown ln Figure 5A, the extended pin member 431 is disposed at each end of elongated brush 43 and is mounted on seat 4310 in which there is provided a spring 4311 in such a manner that the extended pin member 431 can smoothly and resiliently move or slide along the contour of protrusion 401. Furthermore, as shown in Figure 5, elongated brush 43 is actuated by said cylinder 31 to brush over tape portion S2 in order to adhere it to the surface of carton S.
The continuously moving brush 43, resumlng its original position, is confinedly guided by protrusion 401, with the help of said hinge bar 41, it is able to change the brush 43 from a horizontally-disposed position ~o a vertically erected position when said cylinder 31 is moving backward. By so doing, the brush 43 can leave an already sealed carton S untouched in the returning process of brush 43 preventing the adhered tape S2 from being detached and also preventing brush 43 from being excessively worn out.
In order to accommodate cartons of differen-t size, one of the conveyor belts 11 can be adjusted so that the short and elongated brushes 13 and 43, and tape applying means 12, can be movably adjusted to the left or right on the upper and lower frame 30 and 10 so that the distance between brushes can he changed according to the size of the car-ton. The adjustment is effected by means of an elongated worm rod 16, having a turning knob 161 disposed at one end, and said worm rods 16 are horizontally disposed on said upper and lower frame 30 and 10 '~..' 37~)Z~
and fixed in place by nut elements at the opposincJ end so that -the actuation of said worm rods can eE~ect the operation of moving one of said conveyor belts 11 to the left o:r right for changing the distance therebetween and thus the space between the brushes.
To adjustably change the distance between the upper and lower frame 30 and 10, for receiving cartons of different size , there are four vertical worm rods 17 symmetrically and vertically erected in juxtapoeition to the ~our supporting rods of said upper frame 30, with the top ends thereof fixed to the mounting seats 171, respectively, and the bottom ends provided with gear elements (not shown) which are connected to each other by a chain member so that a motor 172, located at the bottom end of a vertically-disposed worm rod 17, can actuate the upper frame 30 to move up or down for effecting the adjustment of the distance therebetween.
The features and operational mode of the present inven-tion are clearly illus~rated by means o~ the accompal1ying drawlngs which are shown and described as below:

DETAILED DESCRIPTION
.
As shown in Figure l, the present invention is structurally in association with an upper frame 30, a lower frame l0, both equipped wi-th conveyor belts ll to transmit a carton to a tape applying means 12, located in symmetry at both , sides of said upper and lower frame 30and 10, respect.ively, where tapes are applied automatlcally along the symmetrlc cdyes of said carton, and the par~ially ~ixed -tapes are Eirst repeateclly brushed over by means o:E a pair of short brushes 13 i.n a hori~ontal direction at both corners of the edges so as to neatly adhere the tapes, then elongated brushes 43, operated by air-actuated cylinders 31, are moved up and down repeatedly in a vertlcal direction to make the rest of said elongated tapes, disposed along the opposing edges, adhere to the surface of said carton when said carton is transmitted to a selected position, so tha-t the sealing o sald carton is achieved automatically without the use of manual labour.
Referring to Figure 7, the flow chart shows that a carton S, transmitted by conveyor belts 11 to a symmetrically located tape applying means 12 in an up and down manner, is attached with sealing tapes along the upper and lower edges.
Then short brushes 13 are actuated by cylinders 15 to brush over the fixed tapes at the corners to neatly adhere the tapes, the reversely moving brush can further flatten the tapes once again, then elongated brushes 43 are moved up and down to brush over the rest of said tapes S2 to complete the automatic sealing process.
Referrlng to Figure 1 and Figure 2, the devlce is provided with a short brush 13 disposed at a proper position near the end of said tape applying means 12, which is able to repeatedly move in a synchronous manner within a pre-set range.
The short brush 13 has a split clamp end 131 which is used to , fix said brush to a chain 132 mounted between a pa:Lr o.E
sprockets 141 and driving gear 19 which engages Witll a rack 151 attached to the front of cylind~r 15, which is controlled to move in dual direc-tions and within a selected range, so -that said shor-t hrush 13 can effect a repeated motlon in pre-set distance. This permits smooth attachment of the tape ends Sl at the corners of sald carton S in a proper order, terminating the first step of the tape-fixing process, as shown in Figure 3.
As further shown in Flgures 1 and 4, said carton S is continuously moved, through the above-mentioned process, by means of a conveyor belt 11 to elongated brushes 43, disposed in juxtaposition to said short brushes 13 but at a proper distance from each other, which are moved repeatedly in a vertic~l direction to flatly adhere the tapes to the surface of said carton lengthwisely along the edges. At bo-th ends of a hinge bar 41, there ar~ at~ached twisting springs 42, and the hinge bar 41 i6 mounted lengthwisely along the brush actuating base 40, the bottom of which is connected to the front end of cylinder 31 by a push bar 311 so that the elonga-ted brush 43 can be repeatedly moved up and down, by sald cylinder, to smoothly brush over the elongated tape portion S2 -to complete the sealing of carton S. There is an extended pin member 431 dlsposed ak each end oE brush 43 and is ~onfinedly guided in a knife-shaped protru~lon 401 on a stop plate of a frame 33 so that extended pin member 431 can be slidably moved along the external contour of protrusion 401. Cylinder 31 and said frame 33 are joined together by means of a support structure 32 with ~l~8~
push bar 311 goin~ thxough the bottom of fr~me 33 and integxcllly connected to brush actuating base 40. As shown ln Figure 5A, the extended pin member 431 is disposed at each end of elongated brush 43 and is mounted on seat 4310 in which there is provided a spring 4311 in such a manner that the extended pin member 431 can smoothly and resiliently move or slide along the contour of protrusion 401. Furthermore, as shown in Figure 5, elongated brush 43 is actuated by said cylinder 31 to brush over tape portion S2 in order to adhere it to the surface of carton S.
The continuously moving brush 43, resumlng its original position, is confinedly guided by protrusion 401, with the help of said hinge bar 41, it is able to change the brush 43 from a horizontally-disposed position ~o a vertically erected position when said cylinder 31 is moving backward. By so doing, the brush 43 can leave an already sealed carton S untouched in the returning process of brush 43 preventing the adhered tape S2 from being detached and also preventing brush 43 from being excessively worn out.
In order to accommodate cartons of differen-t size, one of the conveyor belts 11 can be adjusted so that the short and elongated brushes 13 and 43, and tape applying means 12, can be movably adjusted to the left or right on the upper and lower frame 30 and 10 so that the distance between brushes can he changed according to the size of the car-ton. The adjustment is effected by means of an elongated worm rod 16, having a turning knob 161 disposed at one end, and said worm rods 16 are horizontally disposed on said upper and lower frame 30 and 10 '~..' 37~)Z~
and fixed in place by nut elements at the opposincJ end so that -the actuation of said worm rods can eE~ect the operation of moving one of said conveyor belts 11 to the left o:r right for changing the distance therebetween and thus the space between the brushes.
To adjustably change the distance between the upper and lower frame 30 and 10, for receiving cartons of different size , there are four vertical worm rods 17 symmetrically and vertically erected in juxtapoeition to the ~our supporting rods of said upper frame 30, with the top ends thereof fixed to the mounting seats 171, respectively, and the bottom ends provided with gear elements (not shown) which are connected to each other by a chain member so that a motor 172, located at the bottom end of a vertically-disposed worm rod 17, can actuate the upper frame 30 to move up or down for effecting the adjustment of the distance therebetween.
