The present invention relates to the technical field of printing, and more particularly to an apparatus and a process for printing beer barrels.
Beer barrel is a common container for containing beer. To guarantee the strength of the beer barrel while reducing weight and resisting rust, the beer barrel is usually made of stainless steel. On the body of the beer barrel, related identification information is printed on the body of the beer barrel. In a traditional manufacturing process, a matrix printing tool is provided for printing the identification information on a raw material (such as a stainless steel plate), and then the raw material with the printed identification information is stretched and welded to form the body of the barrel. However, such manufacturing process has the following drawbacks:
If a semi-finished product is scrapped due to an operational error occurred in the stretching and welding processes or any other reasons, the previous printing process will become useless correspondingly, and thus incurring additional manufacturing cost and increasing the manufacturing time.
During the production process, words of a mark may be the same and different, but a beer barrel with all of these words in the mark is molded as a whole. Since the fonts are not all the same, therefore it is necessary to prepare several matrix printing tools with different marks. As a result, the cost for the matrix printing tools and the manufacturing time are increased.
I. Problem to be Solved:
The present invention provides an apparatus and a process for printing barrels after the barrel is stretched and welded to overcome the drawbacks of the traditional manufacturing process which may cause an unnecessary scrap of a semi-finished product when a printed material fails in a stretching or welding process, since the printed material obtained from the previous printing process becomes useless.

III. Beneficial Effects
In summation, the apparatus and process for printing a beer barrel in accordance with the present invention have the following advantages:
With the turntable and the connecting frame having the inner mold and the outer mold with the corresponding identification, the stretched and welded barrel is placed on the turntable the this apparatus and pressed by the outer mold and inner mold for printing, so that labels can be printed onto the sidewall of the barrel, so as to achieve the effect of stretching and welding the barrel before printing the barrel. Such arrangement can overcome the drawback of wasting the previous printing when it is necessary to scrap a semi-finished product of the stretched and welded barrel. This invention can simplify the manufacturing procedure and reduce the manufacturing cost and time.
The matrix in the single inner mold and the matrix in the single outer mold are paired and configured to be corresponsive to a pair of matrix elements for printing a single text, and the matrix is installed onto the connecting frame and the turntable separately, so as to divide the matrix printing tool of labeled identification into a plurality of matrix elements of several single texts. During the production process, some of the texts of the labeled identification are the same and some are different. As a result, it is only necessary to change the required matrix and adjust the order, and the original matrix elements of the same text are kept for use, so as to achieve excellent versatility and interchangeability of the same matrix elements for different labeled identifications. Such arrangement not just saves the time of changing the mold only, but also skips the manufacture of several matrix printing tools for different labeled identifications. The invention reduces the manufacturing cost and time of the mold.
By the principle of controlling the servomotor, the matrix can be positioned more accurately while moving and rotating.
After the connecting frame moves along the X-axis to separate the matrix of the female die structure and the matrix of the male die structure from each other, the sidewall of the barrel is still pressed on and latched to the matrix of the male die structure, so that the turntable drives the barrel to rotate along the Z-axis, wherein the turntable may install barrels of different sizes or specifications. Therefore, it no longer needs to prepare several turntables of different sizes, and this invention reduces the manufacturing cost of the apparatus for printing beer barrels.
The barrel outer-sided printing device, the barrel inner-sided printing device and the barrel driving mechanism of the present invention can be controlled independently, so that there will be enough matrixes on the turntable and the connecting frame, and the corresponding printing position can be found automatically according to the inputted printing content. This invention saves lots of time for changing the text and provides a very convenient effect for imprinting an embossed serial number.
Since the barrel driving mechanism can rotate the barrel on the turntable, therefore the gap between two adjacent texts printed on the barrel can be adjusted to make the printed text very beautiful and the distribution of the texts printed on the outer wall of the barrel can be adjusted.
The technical contents of the present invention will become apparent with the detailed description of preferred embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than restrictive.

Step 1: Install a matrix element onto the Y-axis plane of a connecting frame and the circumferential surface of a turntable separately and arrange and label a plurality of corresponding single texts. In the Step 1, if the text and order of the matrix element used in Step 1 are the same as those of the previously installed matrix element, then the previous matrix element will be kept to achieve the effect of providing excellent versatility and interchangeability of the matrix, and such arrangement not just saves the time of changing the mold only, but also skips the manufacture of several matrix printing tools with different marks. Therefore the invention can save the manufacturing cost and manufacturing time of the mold.
Step 2: Sheath a stretched and welded barrel on the turntable 41, such that the inner side of the barrel is configured to be corresponsive to a matrix 63 of a male die structure in a matrix element, and the outer side of the barrel is configured to be corresponsive to a matrix 63 of a female die structure in the matrix element, and the connecting frame moves the turntable 41 along the X-axis. In addition, a normal printing position is designed between the matrix 63 of the male die structure and the matrix 63 of the female die structure in a single matrix element. Now, the positions of the matrix 63 of the first female die structure and the matrix 63 of the first male die structure are at the printing positions (wherein if the X-axis and the diameter of the turntable are situated on a straight line, the matrix 63 of the connecting frame 31 at the linear position and the matrix 63 of the turntable at the linear position can be used for a normal printing, and such linear positions are printing positions).
Step 3: Move the connecting frame 31 along the X-axis, such that the matrix 63 of the first female die structure touches the sidewall of the barrel, and operates together with the matrix 63 of the first male die structure to print a first text of a mark printed on the sidewall of the barrel, and then move the connecting frame 31 in an opposite direction along the X-axis, such that the matrix 63 of the first female die structure and the matrix 63 of the first male die structure are separated from each other.
Step 4: Move the connecting frame 31 along the Y-axis after the separation of the matrixes 63, such that the matrix of the next female die structure is moved with a corresponding distance to the printing position. Since the printed sidewall of the barrel is latched into the first matrix element, therefore the sidewall of the barrel is still pressed on the matrix of the male die structure when the matrix of the female die structure is separated from the sidewall of the barrel along the X-axis. The turntable drives the barrel to rotate along the Z-axis, and the turntable 41 rotates to a corresponding distance along the Z-axis, and the barrel 5 and the matrix of the next male die structure are also rotated to the printing positions, so that the turntable may mount barrels of different sizes or specifications without requiring the manufacture of several turntables of different sizes. This invention further reduces the manufacturing cost of the apparatus for printing a beer barrel, and the method as described in Step 3 is used for printing the barrel.
Step 5: Use the method as described in Step 4 to print the remaining text, so as to complete pressing the whole mark.
This process can simplify the manufacturing procedure, and improve the interchangeability of the matrix, so as to reduce the manufacturing cost and time of the mold and provide a convenient operation.

This apparatus further comprises a program for embossing serial numbers, and the program can be used for printing a respective serial number to a next barrel, and the serial number is corresponsive to the matrix. When the next barrel is printed, the corresponding matrix is retrieved. For example, if we want to print 20150703-001 on this barrel and 20150703-002 on the next barrel, so that each barrel has a unique serial number, then we will simply need to input a first serial number and then change the serial number according to a sequence without the need of changing text or re-enter the information. The operation is very convenient.

Step 1: Install a matrix element onto the Y-axis plane of a connecting frame and the circumferential surface of a turntable separately and arrange and label a plurality of corresponding single texts, wherein a matrix of a female die structure is installed on the Y-axis plane of the connecting frame, and a matrix of a male die structure is installed on a circumferential surface of the turntable.
Step 2: Place a stretched and welded barrel 5 horizontally on a rotating wheel 84 and move the abutting block 94 downwardly to a middle position of the barrel 5, wherein after the first cylinder 67 drives the 3-jaw chuck 613 to move towards the barrel 5 and touch the barrel 5, the 3-jaw chuck 613 is driven to move continuously until an axial end of the barrel 5 abuts against the 3-jaw chuck 613, and the other end of the barrel 5 abuts against the abutting block 94, and then the 3-jaw chuck 613 clamps the barrel 5 for the positioning purpose, and the abutting block 94 is moved upwardly and the Z-axis cylinder 66 controls the barrel 5 to move towards the turntable 41 and to the printing position.
Step 3: When the first text is printed, the connecting frame 31 automatically finds the matrix of the corresponding female die structure and moves the matrix to the printing position, and the turntable 41 automatically finds the matrix of the corresponding male die structure and rotate the matrix along the Z-axis to the printing position, and the hydraulic cylinder 21 moves the matrix of the female die structure along the X-axis for printing. After the printing is done, the matrix of the female die structure restores its original position along the X-axis, and the barrel 5 is separated from the matrix of the male die structure by the upward movement of the lifting cylinder.
Step 4: When the next text is printed, the 3-jaw chuck is controlled independently to rotate the barrel to an appropriate angle, and then the Step 3 is used for performing the operation.
Step 5. The method as described in Step 4 is used to print the remaining text to complete printing the whole mark.
