Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product data reading device for reading a bar code attached to a product with a bar code scanner.

Conventional technology Conventionally, a bar code scanner was placed in the center of the Satsuka stand, baskets were placed at both ends of the Satsuka stand, and the products picked up from one basket were transferred to the other basket, which was attached to the product. There is a product data reading device that reads a bar code with a bar code scanner.

Problems to be Solved by the Invention Since the barcode scanner is fixedly held, the scanning direction and the scanning range of the laser light from its reading window are constant. On the other hand, the position of the barcode differs depending on the product, and the height of the product to be held also varies depending on the height of the operator. As a result, in order to position the barcode within the scanning range of the laser light from the reading window, an unnatural posture such as adjusting the bending amount of the arm or bending the waist is forced, which deteriorates the scanning performance. However, there is a problem that it is easy to get tired.

Means for Solving the Problems A support portion for rotatably holding a lower portion of a barcode scanner having a reading portion on an operator side with a horizontal rotation axis is provided, and the support portion and the barcode scanner are provided. A locking body that is provided with a plurality of locking portions located on a radius centered on the rotation fulcrum of the barcode scanner on one of the facing portions and that is engaged with any of the locking portions on the other side. An operation that is provided so as to be movable back and forth with respect to these locking portions, and has a grip portion projecting from a front edge of the barcode scanner on the barcode scanner or the support portion and is connected to the locking body. A mechanism was set up.

Action The rotational movement of the barcode scanner is restricted by engaging the locking body with any one of the locking portions, but by gripping the gripping portion and transmitting the operation of the operation mechanism to the locking body. It is possible to retract the locking body from the locking portion and rotate the barcode scanner in the downward direction according to the type of product or the height of the operator. As a result, the barcode can be positioned within the scanning range of the laser light while holding the product in a natural posture, and the barcode reading operation can be performed reliably and easily. In addition, since multiple locking parts are arranged, it is possible to adjust the inclination angle of the barcode scanner in multiple stages. Furthermore, since the operating mechanism projects to the front edge side (operator side) of the barcode scanner, The inclination angle of the cord scanner is easily adjusted.

Embodiment An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 8, a bar code scanner 4 having a reading window 3 on the front surface, a keyboard 6 for inputting product data, and a frame 2 which is a support portion provided in the central portion of the sacker stand 1.
A display 7 for an operator is attached. Further, the main body case 5 of the keyboard 6 is integrally formed with a card insertion portion 5 into which a magnetic card is inserted.
A magnetic data reading unit (not shown) for reading the magnetic data of the magnetic card is built in the lower part of 5a.

As shown in FIG. 7, the frame 2 includes a pair of left and right struts 8, a stanchion cover 9 that covers the outer sides of these struts 8 from the central part to the upper part, and a U-shaped connection that connects the lower parts of the stanchions 8. It has a frame 10 and is configured to be expandable and contractible. That is, the column 8 has a vertically elongated slot 12 and a plurality of mounting holes 13 for inserting the mounting screws 11 screwed into the screw holes (not shown) formed on both inner side surfaces of the connecting frame 10 in the vertical direction. Are arranged in. Therefore, the length of the frame 2 is adjusted by selecting the mounting hole 13 through which the mounting screw 11 is inserted. Furthermore, vertically long ridges 14 are fixed to both outer side surfaces of the connecting frame 10,
A guide member 16 that vertically guides a rectangular tube 15 fixed to these ridges 14 is fixedly erected from the floor surface. Longitudinal grooves 17 are formed on the inner surfaces of these guide members 16 so as to allow the protrusions 14 to escape. The lower part of the frame 2 is fixed to a piston 19 of a hydraulic cylinder 18 fixed to the floor, and the hydraulic cylinder 18 and the hydraulic jack 20 are connected to a pipe 21.
Connected by.

Next, a support structure for the bar code scanner 4 and the keyboard 6 will be described with reference to FIGS. 1 and 2. FIG. 1 is a left side view of the frame 2 with one of the columns 8 removed, and FIG. 2 is a longitudinal left side view of the column 2 in which the lower portion of the bar code scanner 4 is rotatable by a support shaft 22. Held in. The barcode scanner 4 is rotated to the right (operator side) from the vertical posture parallel to the support column 8. The depth dimension of the barcode scanner 4 is set to be smaller than the width of the support column 8. As a result, in the vertical posture, they are located inside the front and rear edges of the column 8. A housing 23 of the barcode scanner 4 has a metal mounting base 24 fixed to the upper surface thereof and opened upward in a U-shape.
A base of a top bar 26, which is a locking body having a pin 25 projecting outward from a free end of rotation, is rotatably held around a support shaft 27 on both outer side faces of the bar. A guide member 28 for guiding along the rotation direction of the cord scanner 4
Is fixed to the inner surface of the column 8, and the guide members 28 are provided with locking holes 29, which are a plurality of locking portions for engaging the pins 25, along the longitudinal direction thereof. Since the stopper bar 26 is made of an elastic material, it can be elastically bent in the plate thickness direction.

The keyboard 6 has a metal base 30 on the lower surface, and the base 30 is opened downward in a U shape, and both sides thereof and both side surfaces of the mounting base 24 can be pivoted up and down by a support shaft 31. Are linked to. These support shafts 31 are located on the front side (right side in FIGS. 1 and 2) when viewed from the operator side. Further, on both sides of the base 30, a plurality of locking portions 32 are arranged in a sawtooth shape on a radius centered on the support shaft 31,
A shaft-shaped locking body 33 that engages with any of these locking portions 32 is held in long holes 34a formed on both sides of the mounting base 24. As shown in FIGS. 2 and 4, these elongated holes 34a are in the direction in which the locking body 33 is advanced and retracted with respect to the locking portion 32.
The locking body 33 is biased by springs 34, one end of which is fixed to both outer side surfaces of the mounting base 24, whereby it is elastically engaged with any one of the locking portions 32.

Next, the structure of the operating mechanism for retracting the locking body 33 from the locking portion 32 and the operating mechanism for retracting the pin 25 of the stopper lever 26 from the locking hole 29 will be described with reference to FIGS. To do. First, FIG. 3 is a plan view in which the upper surface of the base 30 of the keyboard 6 is cut away. In the figure, 35 is a locking part 32 to a locking body.
An operation mechanism for retracting 33 is provided, and a reference numeral 36 is an operation mechanism for retracting the pin 25 of the stopper lever 26 from the locking hole 29. One operation mechanism 35 has a grip portion 37 protruding toward the operator's side when viewed from the operator, and a lever 39 rotatably held by a support shaft 38 on the bottom surface of the mounting base 24, and a lever 39 separated from the support shaft 38, respectively. The wire 40 has one end fixed to the position and the other end fixed to the shaft-like locking body 33. The paths of these wires 40 are pulleys 4 rotatably mounted on the bottom surface of the mounting base 24 and both outer surfaces.
It is defined by 1,42,43. Further, the lever 39 is urged clockwise by the tension of the wire 40 based on the pulling force of the spring 34, but the clockwise rotation range by the stopper pin 44 erected on the bottom surface of the mounting base 24. Is regulated. The other operation mechanism 36 has a lever 47 that has a grip portion 45 that projects toward the front side when viewed from the operator and is rotatably held by a support shaft 46 on the bottom surface of the mounting base 24,
A slide rod having one end rotatably held at a position separated from the support shaft 46 and the other end connected to the stopper bar 26.
Stopper pin 50 for restricting the turning range of lever 47 consisting of 48 and 49 and guide pin 5 for guiding the movement of sliding rods 48 and 49.
The numeral 1 stands on the bottom surface of the mounting base 24. In addition, the sliding rod 4
8, 49 are projected from both outer sides of the mounting base 24, and bent pieces 52 are formed along the stop lever 26 at the protruding ends thereof, and these bent pieces 52 are vertically moved as shown in FIGS. 1 and 2. A long hole 53 that is long in the direction is formed. A screw tube 54 provided upright in the intermediate portion of the stopper bar 26 is inserted into these long holes 53, and as shown in FIG. 5, by screwing a screw 55 from the inside of the bent piece 52 into the screw tube 54, Bending piece 5 of sliding rod 48, 49
2 and the stop lever 26 are connected. A compression spring 56 fitted to the screw rod 54 is interposed between the bending piece 52 and the stop arm 26.

As described above, the rotation range of the lever 39 is determined by the stopper pin 44, but even if the lever 39 is rotated counterclockwise to the limit of the rotation range and the wire 40 is pulled, The rotation range of the lever 39 is set so that the locking body 33 is slightly caught by the opening of the locking portion 32. In this case, there is a margin in the length of the elongated hole 34a so that the locking body 33 can be further separated from the locking portion 32.

Next, FIG. 6 shows a structure for supporting the display 7 on the column 8. FIG. 6 is a vertical sectional side view of the lower portion of the frame 2. The outer casing 57 of the display 7 is a case 58 and a translucent cover.
It is formed by aligning 59 and the opening surfaces of both. A deformed shaft 60 fixedly installed on the columns 8 on both sides is passed through the outer casing 57, and a plurality of locking portions are provided at both ends of the deformed shaft 60 along the radial direction around the deformed shaft 60.
A plate-shaped cam 62 having a serrated shape 61 is fixedly fitted, and a locking piece 63 that elastically engages with any one of these locking portions 61 is erected on the case 58. It is fixed to the boss 64 with a screw. Then, on both sides of the case 58, slit-shaped fitting portions 65 that fit into the cam 62 are formed. Inner walls at both ends of these fitting portions 65 are in contact with both surfaces of the cam 62, whereby the axial movement of the outer casing 57 with respect to the deformed shaft 60 is restricted. Further, the side edge of the cam 62 in the direction around the axis of the deformed shaft 60 faces the inner wall of the fitting portion 65 with a predetermined play, whereby the rotation range of the outer casing 57 with respect to the deformed shaft 60 is increased. It is set to about 15 degrees. Further, the bottom surface of the case 58 was open for inserting the deformed shaft 60 and the cam 62,
A bottom cover 66 is fixed to the bottom surface with screws. Such an indicator 7 is for the operator,
As shown in FIG. 2 and FIG. 2, the display 67 for customers is installed on both ends of the upper portion of the column 8.

In such a configuration, the locking body 33 is biased by the spring 34 and engages with any one of the locking portions 32 of the base 30 of the keyboard 6, whereby the keyboard 6 with the support shaft 31 as a fulcrum.
The rotational movement of the is blocked and the stable state is maintained at a predetermined position. Then, the wire 40 is pulled by gripping the grip portion 37 protruding from the lower part of the front edge of the keyboard 6 toward the operator side and rotating the lever 39 counterclockwise, and the locking body 33 is biased by the spring 34. It retreats from the locking part 32 against. As a result, the keyboard 6 can be tilted around the support shaft 31 at an arbitrary angle. In adjusting the tilt angle of the keyboard 6, the stopper pin in the rotation range of the lever 39
As shown in FIG. 4, the locking body is regulated by 44.
It is possible to maintain the state in which 33 is slightly engaged with the locking portion 32, so that the keyboard 6 does not inadvertently descend due to its own weight. In this state, by rotating the base 30 together with the keyboard 6, the locking body 33 is retracted in the direction away from the locking portion 32 by the component force based on the turning force acting on the keyboard 6, and the rotation of the base 30 is performed. Allow movement. Further, as shown in FIG. 4, a stopper 30a positioned above the uppermost locking portion 32 and a stopper 30b positioned below the lowermost locking portion 32 are formed on both side surfaces of the base 30. By supporting the locking body 33 with these stoppers 30a and 31b, the range of rotation of the keyboard 6 with respect to the mount 24 is restricted.

Further, since the pins 25 of the stopper bar 26 on both sides of the mounting base 24 are engaged with any of the locking holes 29 of the guide member 28, the barcode scanner 4 moves in the rotation direction about the support shaft 22. Although the movement is blocked and the stable state is maintained at a predetermined position, the sliding rods 48, 49 are pulled inward by grasping the grasping portion 45 and rotating the lever 47 counterclockwise, Sliding rod 48,49
Pulls the stop lever 26 inward. As a result, the stopper lever 26 is bent inward and the pin 25 is disengaged from the locking hole 29. As a result, the bar code scanner 4 is centered around the support shaft 31.
Can be tilted from a vertical state parallel to the support column 8 to a downward state. When the lever 47 is released, the stop lever 26 returns to the outside while pulling the sliding rods 48, 49 by its own elasticity, and the pin 25 is engaged with one of the locking holes 29 of the guide member 28.

Further, in the indicator 7, the tip of the locking piece 63 is the locking portion of the cam 62.
Since it is elastically engaged with 61, it remains stable at a predetermined upward angle, but the elevation angle is adjusted by rotating the outer casing 57 around the deformed shaft 60 fixed together with the cam 62. It At this time, the locking piece 63 changes the engaging part 61 to be engaged.

Further, when the pedal 20a of the hydraulic jack 20 is adjusted while being depressed, the hydraulic pressure is supplied to the hydraulic cylinder 18, so that the piston 19
Pushes up the frame 2 and stabilizes the frame 2 at a position where the foot is released from the pedal 20a. When the pedal 20a is depressed to the end, the hydraulic pressure of the hydraulic cylinder 18 is returned to the hydraulic jack 20 so that the frame 2 descends. As a result, the position heights of the barcode scanner 4, the keyboard 6, and the displays 7, 67 can be freely adjusted. Moreover, by using the hydraulic jack 20 as a power source for raising and lowering, it is possible to easily perform the height adjustment work according to the height of the operator with a little labor.

When registering the product data, the operator reads the bar code attached to the product with the bar code scanner 4 in the process of transferring the product taken out from the basket placed at one end of the Satsuka stand 1 to the basket placed at the other end, If the bar code is not attached or the bar code is soiled, the product data is input by the keyboard 6 while alternately viewing the display surface of the quality of the product and the keyboard 6.
In this case, the product and the keyboard 6 are viewed alternately, but as described above, the inclination angle of the keyboard 6 can be adjusted according to the height and posture of the operator.
The keyboard 6 can be seen from the line of sight of the product, and if the keyboard 6 is high for the operator, the keyboard 6 is raised so that the operator can easily operate the keyboard 6 with his / her wrist bent. be able to. In this case, since the keyboard 6 rotates with its front edge side as a rotation fulcrum, the arrangement surface of the keys approaches the operator side, making it easy to reach. On the other hand, when the keyboard 6 is low for the operator, the elevation angle of the keyboard 6 can be made small so that the operator can easily operate the keyboard 6 with the wrist bent naturally. In this case, the work of adjusting the inclination angle of the keyboard 6 is extremely facilitated by gripping the grip portion 37 protruding toward the operator and rotating the lever 39 to rotate the keyboard 6. Moreover, since the keyboard 6 can be adjusted not only in the inclination angle but also in the height, the keyboard 6 is more easily seen and the operability is further improved.

Further, since the inclination angle of the barcode scanner 4 can be adjusted according to the height of the operator, it is not necessary to bend the arm unnaturally and lift the product near the reading window 3 of the barcode scanner 4. The barcode of the product can be opposed to the reading window 3. If the reading window 3 is directed downward, the upper part of the barcode scanner 4 approaches the operator side, and accordingly, the operator is more likely to scan away from the sacker stand 1, but the operator of the barcode scanner 4 is Since the keyboard 6 is moved closer to the operator side with the rotational movement, the keyboard 6 is easily accessible.
In this case, the orientation of the keyboard 6 changes due to the rotation of the barcode scanner 4, but if it is difficult to operate in that orientation, the tilt angle of the keyboard 6 may be readjusted by the above-described operation.

Further, by incorporating the magnetic data reading unit in the main body case 5 of the keyboard 6, it is possible for a customer who uses the magnetic card to settle the price to read the data of the magnetic card in the posture facing the keyboard 6. it can.

Although the input result of the barcode scanner 4 or the keyboard 6 is displayed on the customer display 67, the orientation of the customer display 67 is always oriented in a fixed direction even if the barcode scanner 4 is rotated. Can be maintained in a state.

A plurality of locking portions such as the locking holes 29 may be arranged in the barcode scanner 4, and a locking body that engages with any of these locking portions may be provided in the frame.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the rotational movement of the barcode scanner is restricted by engaging the locking body with any one of the locking portions. By transmitting the operation of the operating mechanism to the locking body, the locking body can be retracted from the locking portion, and the barcode scanner can be rotated downward according to the type of product or the height of the operator.
As a result, the bar code can be positioned within the scanning range of the laser light while holding the product in a natural posture, and therefore, the bar code reading operation can be performed reliably and easily. Since there are multiple stoppers arranged, it is possible to adjust the inclination angle of the barcode scanner in multiple stages. Furthermore, since the operating mechanism projects to the front edge side (operator side) of the barcode scanner, the barcode scanner is There is an effect that the inclination angle of can be easily adjusted.
