Abstract:
A pouch producing machine for producing protective pouches has a feeding device, a gluing device, a glue provider and a cutting-forming device. A sheet of pouch has an upper sheet, a lower sheet, a middle bar and two side bars. The already combined sheet of pouches, after being processed by the machine, becomes an individual pouch having its three sides sealed by the middle bar and the side bars.

Description:
FIELD OF THE INVENTION 
     The present invention generally relates to a pouch producing machine and more particularly to a pouch producing machine for pouches in which collectable items may be stored. 
     BACKGROUND OF THE INVENTION 
     It has been popular for many years to collect series of items, such as baseball cards, and such accumulations bring much pleasure to the collectors. However, those items are often quite flimsy and so are easily damaged when being handled. That damage is detrimental to the appearance of the card and will significantly affect the swap or financial value of the card. Thus it is desirable to store the cards in transparent pouches in which the cards may be maintained in pristine condition. 
     Prior art of producing pouches is cut and sealed manually which is inefficient and accordingly wastes time and mony. Furthermore, the quantity able to be produced per day is limited. 
     The present invention provides an improved pouch producing machine for producing card shields, such as baseball cards, to mitigate and/or obviate the aforementioned problems. 
     SUMMARY OF THE INVENTION 
     The main objective of the invention is to provide an automatic means for producing baseball card shields which automatically manufactures a baseball card shield, including the stages of feeding, gluing and cutting- The automatic means comprises a feeding device, a gluing device and a cutting-forming device. The feeding device transports raw material into the gluing device and the gluing device presses the glued sheet of material on both sides and then transports them into the next device. The cutting-forming device receives the ready-cut sheet of material and cuts the pressed material by a special cutting tool and thus products are ready to be sold on the market. 
     Another objective of the invention is to provide a means which manufactures pouch fully automatically, therefore reducing the expense and time consumption to a minimum. 
     Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings and particularly to FIGS. 1 and 3, a machine for producing protective pouches is provided. 
     The machine for producing protective pouches comprises a feeding device 10, a gluing device 20 and a cutting-forming device 30. The feeding device 10 functions to transport a roll of an upper sheet 11, a roll of a lower sheet 12 and a roll of a middle bar 13 therebetween. 
     The gluing device 20 for providing glue to the upper sheet 11, the lower sheet 12 and the middle bar 13 respectively in their proper positions has a case 21 with a first motor 22 mounted therein and forms a bottom part of the device 20. A disk 23 provided beside the first motor 22, having at least two sensors 231, 232 which are situated at opposite directions is pivotally connected with a link 234. A sensing element 233 is situated below the disk 23. The link 234 engages with an upper plate 235 having a punch 236 and a pressing plate 237. The punch 236 faces downward and is mounted on a bottom face of the upper plate 235 for punching holes in a certain part of pouches for easier cutting. Two groups of opposite transporting wheels 24, 25 are provided on a front part of the gluing device 20. Another two groups of opposite pressing wheels 241, 251 are situated behind the latter group of transporting wheels 24, 25, and the upper sheet 11, the lower sheet 12 and the middle bar 13 are able to be pressed to form a combined sheet of a pouch to be transported to a next device therebetween. A glue provider 18 is provided between the latter group of the transporting wheels 24, 25 and a front group of the pressing wheels 241, 251, as shown in FIGS. 1 and 2. The rotation of the pressing wheels 241, 251 driven by a second motor 26 transports the glued middle bar 13 and passes the middle bar 13 through the upper sheet 11 and the lower sheet 12 (as shown in FIG. 4). A track 27 provided behind the gluing device 20 is designed for the continuous forward moving of the upper sheet 11 and the lower sheet 12, and while the combined sheet of the pouches formed by pressing the middle bar 13 between the upper sheet 11 and the lower sheet 12 passes through the track 27, the combined sheet of the pouches is properly dried. 
     Referring to FIG. 4, a pair of third motors 28 each provided with a shaft 281 to control a group of gears 282, 283 and lower pressing wheels (not shown) are respectively mounted on both sides of the case 21. A group of upper pressing wheels 14, 15 are mounted on top of the lower pressing wheels to allow a side bar 17 to be transported to the center of the gluing device 20 and pressed between the lower pressing wheels and the upper pressing wheels 14, 15. An opening member 29, as shown in FIG. 5, has an inclined surface 292 for opening the upper sheet 11 and the lower sheet 12, and a recess 291 permitting the side bar 17 to be transported between the upper sheet 11 and the lower sheet 12 when the upper sheet 11 and the lower sheet 12 are opened by the opening member 29. 
     It is to be noted that when the disk 23 rotates due to the first motor 22, the sensors 231, 232 are sensed sequentially by the sensing element 233 (as shown in FIG. 3), which activates the third motor 28 to start the feeding of the side bar 17 and to position the middle bar 13 and the side bar 17 at the center and at both sides of the upper sheet 11 and the lower sheet 12 respectively. When the upper plate 235 is pulled by the link 234 due to the rotation of the first motor 22, the punch 236 provided on the bottom of the upper plate 235 will centrally punch a plurality of holes 16 in the upper sheet 11 and the lower sheet 12, the side bar 17 and the middle bar 13 will simultaneously be transported and pressed between the upper sheet 11 and the lower sheet 12. After the abovementioned procedure is finished, the upper sheet 11 and the lower sheet 12 with the middle bar 13 and the side bar 17 therebetween are then transported to the track 27 to be received by the cutting-forming device 30 (as shown in FIGS. 1 and 6). 
     The cutting-forming device 30 comprises a cutting seat 31 driven by a powered shaft 33 and a base 32, so that the cutting seat 31 is able to be moved up and down relative to the base 32. A knife (not shown) mounted under the cutting seat 31 is subtantially configured as a &#34;Z&#34;, therefore, pouches will be cut along one side bar 17, one middle bar 13 of a sheet of the pouches and another side bar 17 of another sheet of the pouches when the cutting seat 31 moves close to the base 32 along with the knife, as shown in FIG. 7. After all the above mentioned processes are completed, two sheets of individual baseball card shields are presented because of the centrally pounched holes 16. 
     From the foregoing, it is seen that the objects hereinbefore set forth may readily and efficiently be attained, and since certain changes may be made in the above construction and different embodiments of the invention without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
