Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a semiconductor container marking device.

As shown in Figure 1, small unit semiconductor containers a', a''
, . . . A mark indicating the performance of the semiconductor container is attached to the surface of the series of semiconductor containers a before being cut into pieces.

This performance is determined by each unit semiconductor container ja', a'',...
(hereinafter represented only by a'), different marks must be attached depending on the different performance. However, since the series of semiconductor containers a before being cut into unit semiconductor containers a' consists of a large number of unit semiconductor containers a', it is inefficient to manually mark them while performing performance detection. No work is allowed.
Also, the semiconductor container a is usually about 5wn in width,
Since it is necessary to add symbols and numbers over three lines of 3 to 4 characters per line, there is a drawback that if such small symbols and numbers are added in printed letters, they become unclear. .
This invention automatically detects the performance of a series of semiconductor containers (a) when they are being transferred along a guide rail, and collects typefaces for different marks indicating the performance. Select the typeface of the mark, apply ink well, and transfer it to a mark transfer cylinder made of a rubber roll, etc., and then offset the mark to the surface of the semiconductor container when the semiconductor container comes below the mark transfer cylinder. By transferring a clear performance mark to the surface of the unit semiconductor container a'' of a series of semiconductor containers, it is possible to quickly and automatically imprint a clear performance mark on the surface of the unit semiconductor container a'' of a series of semiconductor containers, and by applying ink to the type or pressing a mark transfer cylinder onto the type. The object of the present invention is to provide a semiconductor container marking device which is capable of obtaining a clearer performance mark by preventing the position of the type from being moved by a brake device.The structure thereof will be explained based on the illustrated embodiment.

When the semiconductor container a is sent to a predetermined position, for example, a printing position, the device 1 is stopped, and the device 2 is operated, and the semiconductor container a is thereafter converted into a unit semiconductor container. The device 1 is sent intermittently at a pitch of a'', and when a predetermined mark is completed on a series of semiconductor containers a, the device 1 is put to rest, and the device 1 works again to transfer the semiconductor containers across a large width. .

It is designed so that they are in contact with each other.

In addition, 25 is a coil spring and has a pin 26 planted in the forward machine frame 8 and a pin 27 (third and fourth) planted in the swinging rod 21.

A brake shoe 281 is provided which applies a brake by coming into contact with the brake disc 11'' provided on the shaft of the machine.
The mark transfer cylinder D is brought into contact with the type cylinder A after it comes into contact with the brake disc 1'' to perform a braking action and fix the type cylinder A.

In addition to the two cams 19 and 38, a plurality of sensors 3 are mounted on the shaft 18 which is driven by the belt from the motor 17 as described above.
A slitting disk 40 is provided which cooperates with the slitting disk 9, and in combination with an electric memory controller F to be described later, allows the entire apparatus to perform a series of operations sequentially. The shafts 11'' and 28'' of the two pulse motors 11 and 28 (see Figures 3 and 5) also have sensors 41 and 42 fixed to the rear machine frame 10, respectively.
(See especially FIG. 5) and these cooperating slitting machines 43
, 44 are provided. Further, a semiconductor container performance detector E is provided on the passage path of the series of semiconductor containers a, and the detector E
The detected performance is stored in an electrical memory controller F, and via the controller F the pulse motor 11 and sensor

When the motor 13 starts, the rolls 5 and 6 of the inking device B and the ink cylinder 7 rotate, and the ink transfer cylinder C also starts rotating. When the motor 17 starts, the shaft 18, and therefore the first and second cams, start rotating. 19 and 38 also rotate, and the action of the swinging rod 21 and the first cam 19 causes the ink transfer cylinder C to move left and right, and the action of the second cam 38 and the swinging rod 34 causes the mark transfer cylinder D to move up and down. Movements are now performed regularly, maintaining a certain temporal relationship. Since this embodiment has the above-mentioned configuration, as shown in FIG. 1, a series of semiconductor containers a are transferred to the mark location G of the mark transfer cylinder D by the wide intermittent transfer device 1 shown in FIG. As it is sent downward, a series of semiconductor containers a
On the way, the performance of each unit semiconductor container a'', a'', . The performance of is memorized as a group.

Next, the unit semiconductor container a″ at the tip of the series of semiconductor containers a
is located below the mark location G of the mark transfer cylinder D, the first large-width intermittent transfer device 1 separates from the series of semiconductor containers a, and then the small width intermittent transfer device 1 moves away from the series of semiconductor containers a, and then transfers the small width intermittent transfer device 1 with the length p of the unit semiconductor container j as the intermittent transfer pitch. The width intermittent transfer device (2) starts working, and the opposing clamping levers D, d grip both sides of the series of semiconductor containers (a), and stand by in this state.

When the occurrence of this state is transmitted to the electrical storage controller F, a signal stored in the controller F according to the performance of the first unit semiconductor container a'' of the series of semiconductor containers a is printed. Pulse motor 11 and sensor 41 of cylinder A are energized to rotate type cylinder A as much as necessary to direct the type 3 representing the performance towards ink transfer cylinder C.

Next, a signal is sent from the controller F to the motor 17, and the pulley 1
C'', belt 15'', and pulley 1'' to rotate the shaft 18, actuate the first cam 19, and swing the swinging rod 21.
The ink transfer cylinder C is moved toward the type cylinder A, the type 3 is inked, and then returned to its original position.

Inking of the type 3 is carried out with the brake shoe 123 in contact with the brake disc 1'' to fix the type cylinder A.The ink transfer cylinder C is activated by the motor 13 as soon as the semiconductor container marking device is started. When starting and starting to rotate through gear 13'', gear 14, gear 15, gear 16 and moving towards type cylinder A, gear 16 is connected to gear 1.
5, the rotation stops, and when the ink transfer cylinder C returns to its original position, the gear 16 meshes with the gear 15 and the ink transfer cylinder C rotates again.

When the ink transfer cylinder C separates from the type cylinder A, a signal is sent to the controller F, which issues commands to the pulse motor 11 and the sensor 41, and
is rotated 9 degrees so as to face the lower mark transfer cylinder D and then stopped.

The mark transfer cylinder D is always located between the type cylinder A and the first unit semiconductor container j of the series of semiconductor containers a which is located on the guide rail 2 for transporting the semiconductor containers below, but the ink transfer cylinder At the same time as C is separated from the type cylinder A, it is raised by the swinging rod 34 by the operation of the second cam 38, and the mark is transferred to the outer periphery of the mark transfer cylinder D by the type 3.

During this transfer, the mark type cylinder A is placed on the brake shoe 2.
81 is fixed by coming into contact with the brake disc 1. Before the cylinder D rises toward the type cylinder A, the pulse motor 28 is rotated by a predetermined angle according to a command from the controller F so that the required position is directed toward the type 3.) Marks are transferred. The mark transfer cylinder D begins to descend due to the rotation of the swinging rod 34 caused by the operation of the second cam 38, and a signal due to this descent is immediately sent to the controller F, and the mark transfer cylinder D is started by the signal from the controller F. The pulse motor 28 of the cylinder D is started, and the mark transfer cylinder D rotates 180 degrees to position the mark above the unit semiconductor container y, that is, at the mark location G. Subsequently, the mark transfer cylinder D is lowered to remove the mark. It is transferred onto the surface of the first unit semiconductor container a''.

After the transfer, the mark transfer cylinder D rises again, reaches the intermediate position, and stops, and the motor 17 also stops. Mark transfer cylinder D
When the unit returns to its original position, a signal is sent from the controller F to the intermittent transfer device (2), which moves the series of semiconductor containers a by a pitch of p, and marks the second unit semiconductor container a'' at the position G.
position it below. In this way, when the series of semiconductor containers a have been sent successively at a pitch p, the clamping levers D and d of the small width intermittent transfer device 2 are opened and the device returns to its original position.
When the above series of operations is repeated and all markings have been made on the surfaces of the series of semiconductor containers a, the intermittent transfer device (2) returns to its original position and enters a pause state for a while, as described above. Once transmitted to the controller F, the large width intermittent transfer device 1 is actuated by the signal from the controller F, and at the same time sends out the marked semiconductor container a, it also transfers the first unit semiconductor container of a new series of semiconductor containers a. is positioned below the mark location G of the mark transfer cylinder D, and when a new series of semiconductor containers is in this position, the clamping lever D of the front small/large width intermittent transfer device ■ is moved.
, d grab the first unit semiconductor container and wait for a signal from the controller F.

The series of operations described above is performed by the electric memory controller F, the slit disk 40 and sensor 39 provided on the shaft 18, or the slit disk 43 and sensor 41 provided on the rotating shaft of the pulse motor 11, and the pulse motor 28. The electrical configuration is controlled by a slit disk 44, a sensor 42, etc. provided on the rotating shaft of the machine, and its electrical configuration can be easily created as needed using current electronics technology, and is shown in a block diagram. A detailed explanation of the invention will be omitted, only showing the installation positions of the electric storage control device F, the slit disk, and the sensor.

According to the above embodiment, since the mark is not directly applied by printing but by an offset type, even a small mark b extending over several lines can be imprinted in detail. In addition, even if the performance of the unit semiconductor container a'' is, for example, one type, it is possible to sufficiently handle the performance by pre-embedding several types of type 3 on the type type cylinder A for marking. Furthermore, after the mark transferred from the mark type cylinder A to the mark transfer cylinder D is transferred to the semiconductor container a', the mark type cylinder A on the mark transfer cylinder D is transferred to the mark type cylinder A.
The transferred mark becomes thinner, but the thinner mark transfer cylinder D contacts the mark type 3 of the mark type cylinder A again, and the mark becomes darker. Since the mark type cylinder A is braked and fixed before contacting the ink transfer cylinder C1 and the mark transfer cylinder D, a clear mark is always transferred to the surface of the unit semiconductor container a''. When the outer circumference of the transfer cylinder D rises toward the mark type cylinder A, the position where the mark is transferred by the mark type cylinder A on the mark transfer cylinder D corresponds to each mark type type 3. Since it is constant, there is no need to always have a new surface on which no marks have been transferred, and there is no need to perform an operation to erase the marks transferred to the mark transfer cylinder D one by one. According to the semiconductor container marking device according to the present invention, even small marks can be stamped clearly and efficiently on the narrow surfaces of a series of semiconductor containers.
