Description

  The present invention relates to a pseudo core for mounting a label in a mold in label insert molding in which a synthetic resin is integrally formed on a label printed with various designs such as desired characters and pictures mounted in the mold. The present invention relates to a label delivery method to a pseudo core that delivers a label with high positional accuracy and an apparatus therefor.

  In label insert molding for molding a molded product such as a cup or container made of a synthetic resin in which a label on which various designs such as desired characters and pictures are printed is integrated, as shown in, for example, Patent Document 1 After holding the label in a state where the shape is matched to the molded product and the label is wound around the pseudo core having a large number of suction holes on the outer surface, the label is sucked and held with the pseudo core entering the mold. At the same time as releasing the label, the label is sucked in the mold to mount the label in the mold.

  In the label mounting method described above, when sucking and holding the label wound around the outer surface of the pseudo core, a part of the outer surface of the pseudo core is brought into contact with the central portion in the longitudinal direction of the accumulated uppermost label. Alternatively, the labels are sucked close to each other and wound around the entire outer surface of the pseudo core while elastically deforming the label by the suction force.

  However, in the above-described method for delivering the label to the pseudo core, the longitudinal edge of the label is sucked and wound around the outer surface of the pseudo core. A negative pressure (vacuum) generator must be used, and the delivery device itself has the problem of increasing the size and cost.

Further, when the label is wound around the outer surface while elastically deforming the label by the suction force by the pseudo core, the posture of the label, particularly the posture of the edge in the longitudinal direction, is easily disturbed, and the winding state of the label with respect to the pseudo core is easily displaced. . In such a state, when the molded product is molded by mounting the label held on the pseudo core in the mold, the label integrated on the surface of the molded product is displaced or the label is formed on the surface of the molded product. No wrinkles occurred and the molding was defective.
Japanese Patent Laid-Open No. 5-285981

  The problem to be solved is that the label cannot be delivered to the pseudo core with high positional accuracy. Further, the label delivery device for the pseudo core is increased in size and cost.

The formed label is held in a deformed state in close contact with the inner surface thereof, and can be delivered to the pseudo core entering the hollow portion.

The label delivery method according to claim 6 is a label for forming a molded product having a label integrated on the surface by injecting a synthetic resin after mounting the label adsorbed in a wound state on the outer surface of the pseudo core into the mold. In insert molding, the inner surface has a hollow portion that substantially matches the outer shape of the pseudo core and has an insertion opening on the side, and each of the insertion openings is located adjacent to each other and arranged adjacently. A pseudo core that enters the hollow portion of the pseudo mold after the label held by suction is entered into the hollow portion while being elastically deformed into the hollow portion and held along the inner surface of the hollow portion. It is characterized in that a label is sucked and held on the outer surface of the paper so that it can be delivered.

  According to the present invention, when a label is delivered to the pseudo core, it is possible to reduce the occurrence of defective molding by delivering the label in a positioned state. By reducing the suction force of the label by the pseudo core, the device itself can be reduced in size and cost.

  According to the present invention, the best mode is to deliver the label to be held by the pseudo core in a state of being deformed so as to coincide with the holding state by the pseudo mold.

Position the label at a certain height.

  The slider 7 is attached with a lifting drive member 9 such as a cylinder having an axis in the vertical direction or a feed screw connected to an electric motor. A pair of guide shafts 11 having axis lines in the vertical direction are supported by the sliders 7 corresponding to both sides of the lifting drive member 9 so as to slide in the vertical direction, and the operating shaft 9a of the lifting drive member 9 and each guide shaft 11 are supported. The base end of the mounting plate 13 is fixed to the lower part of the mounting plate 13. The mounting plate 13 is provided with three arms 13a, 13b, and 13c extending in a direction perpendicular to the longitudinal direction of the traveling frame 5 (hereinafter, this direction is referred to as the front-rear direction) via predetermined gaps 13d and 13e described later. A pair of front and rear suction members 15a, 15b and 15c, each consisting of a suction cup with the suction surface facing downward, are attached to the lower surface of the distal end of the arm 13a located at the center and the lower surfaces of the distal ends of the arms 13b and 13c located on both sides. . The suction members 15b and 15c located on both sides are set so that their suction surfaces are located slightly above the suction member 15a located at the center.

The suction member 15a located at the center is slidably supported by the arm 13a and attached to the lower portion of the shaft 18 urged downward by the elastic member 16 such as a compression spring. Further, a negative pressure (vacuum) generator (not shown) is connected to the suction member 15a located in the center and the suction members 15b and 15c located on both sides via valves (not shown) that are separately controlled to open and close. Thus, the suction member 15a and the suction members 15b and 15c are controlled by suction separately.

The movable body 19 is reciprocated between a label receiving position and a delivery position to a pseudo core 21 (to be described later) by a reciprocating device (not shown) such as a belt driving mechanism, a feed screw mechanism, a cylinder, or a linear motor connected thereto. Move.

  A pseudo mold 23 is attached to the movable body 19. The pseudo mold 23 has a width in the front-rear direction that is slightly shorter than the front-rear width of the pair of adsorbing members 15a, 15b, and 15c. The width in the left-right direction is the interval between the gaps 13d and 13e. The hollow portion 23a whose inner surface has a frustoconical shape, a cylindrical shape, a rectangular tube shape, or the like is formed. Further, an opening 23b having a predetermined width extending in the front-rear direction at the position of the arm 13a is formed in the upper portion of the pseudo mold 23 so as to communicate with the inside.

A tapered surface 23c is formed on the upper surface of the pseudo mold 23 corresponding to the side edge of the opening 23b, and this tapered surface 23c is used when the label 25 is inserted into the hollow portion 23a of the pseudo mold 23. , Guide it so that both sides are curved.

A large number of suction holes 23d connected to a negative pressure (vacuum) generator are formed in the pseudo mold 23 on the inner surface of the hollow portion 23a, and the label 25 inserted into the hollow portion 23a is sucked into the negative portion with a negative pressure to be in close contact with the inner surface. Let

  The pseudo core 21 is controlled to move to the label delivery position. The pseudo core 21 is attached to a chuck plate 27 to which a chuck member 29 for holding a molded product (not shown) is attached in a molded product take-out machine (none of which is shown) mounted on a resin molding machine, for example. That is, a chuck member 29 such as an adsorbing member for holding a molded product is attached to one surface of the chuck plate 27 and the pseudo core 21 is attached to the other surface, and the chuck plate 27 is 180 degrees horizontally. The chuck member 29 and the pseudo core 21 are selectively opposed to the mold 31 by selectively controlling the rotation.

  The pseudo core 21 has an outer shape that substantially coincides with a molded product in which the label 25 is integrally formed on the surface, and a plurality of suction holes 21 a connected to a negative pressure (vacuum) generator are formed on the outer surface. The pseudo core 21 is sucked and held with the label 25 wound around the outer surface thereof. The pseudo core 21 is connected to a pressure generating device (not shown) as necessary, and when the pseudo core 21 mounts the label 25 in the recess 31a of the mold 31, the suction state is released. The label 25 may be attached by being pressed against the inner surface of the recess 31a of the mold 31 by jetting compressed air from the suction hole 21a at substantially the same timing as the above.

Next, the delivery operation and method of the label 25 to the pseudo core 21 will be described.
After driving the reciprocating drive device to move the slider 7 to the label take-out position of the traveling frame 5, the elevating drive member 9 is driven so that the suction members 15 a, 15 b and 15 c are placed on the upper surface of the label 25 of the uppermost layer of the label group 6. In contact with or close to each other, the center portion in the longitudinal direction of the label 25 is sucked and held by the suction member 15a at the center portion, and the both sides in the longitudinal direction of the label 25 are sucked and held by the suction members 15b and 15c located on both sides.

At this time, the suction member 15a located in the center is set so that the suction surface is located below the suction surfaces of the other suction members 15b and 15c located on both sides. When it comes into contact, it moves upward against the elastic force of the elastic member 16 and becomes substantially flush with the suction surfaces of the other suction members 15b and 15c. (See FIG. 4).

  Next, the elevating drive member 9 is moved backward to move the adsorbing members 15a, 15b and 15c adsorbing the label 25 upward, and then the reciprocating drive device is moved backward to return the slider 7 to the label supply position. When 15a, 15b and 15c are moved upward, the adsorbing member 15a that adsorbs the central portion of the label 25 moves downward by the elastic force of the elastic member 16 and lifts both sides ahead of the central portion, and is located in the lower layer. The label 25 adsorbed from the group 6 is reliably separated (see FIG. 5).

  Next, the lifting drive member 9 is driven to move the mounting plate 13 downward, and at the same time the suction by the suction members 15b and 15c on both sides is canceled while the suction state of the label 25 by the suction member 15a at the center is maintained. The label 25 sucked and held by the suction member 15a at the center is pushed into the hollow part 23a of the pseudo mold 23 through the opening 23b. At this time, since the adsorbed state on both sides of the label 25 is released and is in a free state, both sides of the label 25 are bent upward with the air resistance at the time of lowering so that the label 25 is smoothly pushed into the opening 23b. Make it. (See FIGS. 6 and 7).

  When the label 25 is pushed into the hollow portion 23a while being elastically deformed, the label 25 is elastically restored in the hollow portion 23a and deformed along the inner surface of the hollow portion 23a. At this time, the label 25 in the hollow portion 23a is pressed and brought into close contact with the inner surface by the suction force acting through the suction hole 23d.

  After releasing the suction of the center portion of the label 25 by the suction member 15a in the above state, the lifting drive member 9 is moved back to move the mounting plate 13 upward to return to the original position, and the label 25 with respect to the pseudo mold 23 is moved. Finish wearing.

  Next, after moving the chuck plate 27 and causing the pseudo core 21 to enter the hollow portion 23a of the pseudo mold 23 held in a state where the label 25 is in close contact with the inner surface, the label 25 by the suction hole 23d is moved. The label 25 is sucked by the entire outer surface of the pseudo core 21 by the suction force acting through the suction hole 21a at the same time as the suction is released, and the label 25 in the pseudo mold 23 is elastically deformed according to the inner surface shape of the hollow portion 23a. As it is, it is transferred to the pseudo core 21. At this time, since the label 25 itself is deformed in a shape that matches the inner surface of the hollow portion 23a of the pseudo mold 23 that matches the outer shape of the pseudo core 21, the label 25 is displaced during delivery to the pseudo core 21. Can be passed (see FIG. 8).

  The pseudo core 21 adsorbed with the label 25 wound around the outer surface as described above enters the recess 31a of the mold 31 of the resin molding machine by the movement control of the chuck plate 27, and then the adsorbing is released. By doing so, the label 25 is mounted in the mold 31. At this time, the label 25 may be brought into close contact with the inner surface of the recess 31a by releasing the suction of the label 25 by the pseudo core 21 and simultaneously forming a negative pressure in the recess 31a of the mold 31 (see FIG. 9).

  In this embodiment, since the label 25 is delivered to the pseudo core 21 in a positioning state in which the label 25 is deformed so as to match the holding state of the pseudo core 21 by the pseudo mold 23, the label 25 is displaced at the time of delivery to the pseudo core 21. Can be mounted in a predetermined posture with respect to the inside of the mold, thereby preventing a molding defect from occurring. Moreover, as a negative pressure (vacuum) generating device connected to the pseudo core 21, a small device with low output can be used, and the device itself can be reduced in size and cost.

The present invention can be modified as follows.
1. In this embodiment, the label 25 is mounted in the hollow portion 23a through the opening 23b formed on the upper surface of the pseudo mold 23. However, the opening 23b is provided on the side of the pseudo mold 23. The label 25 may be mounted in the hollow portion 23a from the side.

2. As shown in FIG. 10, a ruler plate 103 connected to an operating member 101 such as an air cylinder is provided on the rear surface side of the pseudo mold 23, and when the label 25 is mounted in the hollow portion 23 a of the pseudo mold 23. The actuating member 101 is actuated to press the ruler plate 103 against one end of the label 25 so that the label 25 can be positioned relative to the pseudo mold 23.

3. In the above description, the configuration in which the pseudo core is attached to the chuck plate of the molded article take-out machine has been described as an example. However, the pseudo core of the present invention is not limited to the above example, and the apparatus moves only the pseudo core alone. It may be provided.

4). In the above description, among the adsorption members 13a, 13b and 13c, the adsorption members 13b and 13c located on both sides are fixedly attached and the central adsorption member 13a can be moved in the vertical direction. Although it was set as the structure attached so that it may be located below adsorption | suction member 13b * 13c, the structure attached fixedly so that each adsorption | suction member 13a, 13b * 13c may correspond to an adsorption | suction holding surface may be sufficient. In this configuration, when taking out the uppermost label 25 from the label group 6, there is a possibility that the uppermost label 25 and the label group 6 cannot be reliably separated. A separating member such as a claw or an air jet member may be provided so that the uppermost label 25 can be separated and removed from the label group 6 with certainty.

5. In the above description, the example in which one label 25 is delivered has been described. However, as shown in FIG. In other words, two mounting plates 113 and 115 having a predetermined distance in the vertical direction are fixed to the lower end portions of the operating shaft 9a of the elevating member 9 and the guide shaft 11, and the base end side is connected to the vertical direction. Support to move with the stroke. Three arms 113a, 113b, 113c, 115a, 115b, and 115c (the central arms are 113a and 115a) are arranged at predetermined intervals on each mounting plate 113 and 115, respectively, and a pseudo mold 117 to be described later. 119, 121 and 123 are provided so as to extend to the lower surfaces of the front ends of the arms 113a, 113b and 113c, 115a, 115b and 115c, and a pair of front and rear adsorption members 125a, 125b and 125c, 127a and 127b and 127c ( Attach the central suction member to 125a and 127a).

  Of the mounting plates 129 and 131 provided at predetermined intervals in the vertical direction, the lower mounting plate 131 has a vertical axis and is supported so as to slide on the main body 3. And it is fixed to an elevating member 116 such as a cylinder fixed to the main body 3, and is reciprocated between a position approaching the upper mounting plate 129 and a position separating downward by the operation of the elevating member 116. Then, pseudo molds 117, 119, 121, and 123 are attached to the upper mounting plate 129 and the lower mounting plate 131, and one of the pseudo molds 117, 119, 121, and 123, A direction close to other pseudo molds 119 and 123 provided on the same plane by operating members 133 and 135 such as cylinders supported and supported by the mounting plates 129 and 131 in a horizontal direction; It is moved in the direction of separating. A ruler plate (not shown) connected to an operating member (not shown) such as a cylinder described in the embodiment is arranged behind each of the pseudo molds 117, 119, 121, and 123. Positioning is made in contact with the labels 25 delivered to 117, 119 and 121, 123.

  When a plurality of labels are attached to the mold, the plurality of recesses to which each label is attached are formed in a state where they are close to each other. On the other hand, when the label 25 is attached to the pseudo molds 117, 119, 121, 123, since the labels are in an unfolded state, the pseudo molds 117, 119, 121, 123 are not less than the width in the longitudinal direction of the label 25. After receiving the label 25, it is necessary to make the mutual interval of the pseudo molds 117 · 119, 121 · 123 coincide with the mutual interval of the recesses in the die.

  In the embodiment shown in FIG. 11, the mounting plates 113 and 115 to which the adsorbing members 125a, 125b, 125c, 127a, 127b, and 127c are attached after the labels 25 are delivered to the pseudo molds 117, 119, 121, and 123, respectively. In a state of being separated from the pseudo molds 117 and 119, 121 and 123, the elevating member 116 is operated to move the lower frame 131 upward and the operating members 133 and 135 are operated to be connected to each other. , 123 are moved to the other pseudo mold 117, 121 side, and the pseudo molds 117, 119, 121, 123 are brought close to each other so that the mutual interval matches the mutual interval of the recesses in the mold (see FIG. 12). ).

In addition, since the receiving operation | movement of the label 25 with respect to the pseudo | simulation metal mold | die 117 * 119, 121 * 123, a ruler operation | movement, and the delivery operation | movement with respect to the pseudo | simulation core 21 are the same, the detailed description is abbreviate | omitted. The same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In order to simultaneously deliver a plurality of labels 25 held in each pseudo mold 23 to the corresponding pseudo cores 21, the pseudo cores 21 are close to each other in consideration of the spacing between the cavities in the mold. It is necessary to pass in the state. For this reason, in the embodiment shown in FIG. 11, when the labels 25 are attached to the respective pseudo molds 23, the pseudo molds 23 are separated from each other. When the label 25 is transferred to the pseudo core, the pseudo molds 23 need to be brought close to each other according to the cavity distance of the mold. For this reason, the label delivery device requires a moving mechanism for bringing the pseudo molds 23 close to each other, which complicates the structure of the device and takes time for delivery.

The present embodiment relates to a label delivery device 201 for solving the above-described problem. Below, the label delivery apparatus 201 is demonstrated according to a figure.

The traveling body 231 is connected to an electric motor (not shown) such as a servomotor capable of numerical control, and a feed screw (not shown) that rotates. It is reciprocated by a conventionally known reciprocating drive mechanism such as a meshed feed screw driving mechanism or a belt driving mechanism in which a part of a timing belt (not shown) that is connected to an electric motor is fixed to the traveling body 231.

  A mounting frame 235 is supported on the traveling body 231 so as to be able to reciprocate with a required stroke in the axial direction of the pseudo mold 204. The attachment frame 235 is reciprocated in the axial direction of the pseudo mold 204 by a forward / reverse operation member 237 such as an air cylinder fixed to the traveling body 231. The mounting frame 235 has a horizontal length that allows each pseudo core 205 to be described later to be positioned on the front surface of the opposing cavities when the traveling body 231 moves to the mold 241 side of the traveling frame 229.

  Two pseudo cores 205 are attached to the attachment frame 235 so as to face each of the pseudo molds 204. Each pseudo core 205 has a shape that can be inserted into the hollow portion 204a of the opposing pseudo mold 204, and a plurality of suction holes 205a connected to a negative pressure (vacuum) generator are formed on the outer surface thereof. Each pseudo core 205 is reciprocated between an insertion position where the pseudo core 205 is inserted into the hollow portion 204a of the pseudo mold 204 and a separation position where the pseudo core 205 is removed from the hollow portion 204a. Is done.

Next, the delivery operation and method of the label 203 by the label delivery device 201 will be described.
First, with the pseudo cores 205 facing each pseudo mold 204 being spaced apart, the lower surface of the label 203 is moved by the respective adsorbing members 219 swinging on the lower surface of the lowermost label 203 accumulated in each label stock portion 213. Are adsorbed and retained. At this time, as shown in FIG. 17, the two suction cups 219a that adsorb the lower surface of each label 203 are moved toward each other, and a part of the adsorbed label 203 is picked out from the opening 207a. In this state, the swinging member 217 is operated to swing the swinging arm 215 toward the insertion opening 204b side of each pseudo mold 204, and as shown in FIG. The part is removed from the opening part 207a and moved to the side of the corresponding opening part 204b, which is the side of the corresponding pseudo mold 204.
During the swinging of the suction member 219, the suction cups 219a that suck the label 203 are moved away from each other to make the label 203 flat.

Next, as shown in FIGS. 19 and 20, the horizontal operation member 221 is operated, and each push arm 227 that has moved to the non-interference position with respect to the moving label 203 is moved to the corresponding pseudo mold 204 side. The sucker 219a sucking the label 203 is opposed to the surface of the label 203 opposite to the sucking side. At this time, a part of the label 203 sucked and held by each suction member 219 is sucked by the suction cup 227a of each push arm 227.

Next, as shown in FIG. 21, the pushing operation member 225 is operated at a timing substantially synchronized with the suction release of the label 203 by each suction member 219, and the pushing arm 227 is moved from the insertion opening 204b to the hollow portion 204a of the pseudo mold 204. Then, the label 203 adsorbed and held by the suction cup 227a is pushed into the hollow portion 204a while being elastically deformed. As a result, the label 203 pushed into the hollow portion 204a is adsorbed over the entire inner surface of the hollow portion 204a by the negative pressure acting through the suction hole 204c while returning elastically in the hollow portion 204a. It is held in the state. Further, in synchronization with the operation of the pushing operation member 225, the swinging member 217 is moved back to move the adsorption member 219 to the lower surface side of the label 203 to be delivered next in the lowest layer accumulated in the label stock portion 213. And adsorb.

  After the above operation, as shown in FIG. 22, the pushing operation member 225 is moved back to move the pushing arm 227 from which the suction of the label 203 by the suction cup 227 a has been released out of the pseudo mold 204, and then the horizontal working member 221 is moved. It returns to return the pushing arm 227 to the original position separated from the pseudo mold 204.

  After the above operation, as shown in FIG. 23, the operating member 211 is operated to move the pseudo molds 204 that have attracted the labels 203 into the hollow portions 204a toward the opposing pseudo cores 205. Next, as shown in FIG. 24, the forward / reverse operation member 237 is operated to move the pseudo cores 205 toward the opposing pseudo molds 204 to be inserted into the hollow portions 204a. In this state, the suction of the label 203 by the suction hole 204c is released, and the label 203 is sucked so as to be wound around the entire outer surface of the pseudo core 205 by the negative pressure acting through the suction hole 205a of the pseudo core 205.

Then, the label 203 is transferred from the pseudo mold 204 to the pseudo core 205 by returning the pseudo core 205 sucked in a state in which the label 203 is wound over the entire outer surface by moving the forward / backward moving operation member 237 back. .

  Then, each pseudo core 205 adsorbed in a state where the label 203 is wound over the entire outer surface as the electric motor is driven is moved to the mold 241 side so as to be opposed to each of the cavities 241a. Next, after operating the forward / reverse operation member 237 to position the pseudo cores 205 in the cavities 241a, the suction by the suction holes 205a is released and the labels 203 are mounted in the cavities 241a. (Refer to FIG. 25 and FIG. 26)

Next, the forward / reverse operation member 237 is moved backward to cause each pseudo core 205 to come out of the cavity 241a of the mold 241, and then the electric motor is moved back to return the pseudo core 205 to the original position. The attachment of the label 203 to 241 is ended. (See Figure 26)

  In this embodiment, at least the label 203 is inserted into the hollow portion 204a of the pseudo mold 204 to be mounted in a state where the label 203 is wound around the entire outer surface of the pseudo core 205. The two pseudo molds 204 can be provided close to each other so as to coincide with the arrangement state of the cavities 241 a in the mold 241. As a result, it is not necessary to provide a mechanism for moving the pseudo mold in the horizontal direction as in the examples shown in FIGS. 11 and 12 of the present invention, and the apparatus itself can be downsized.

  The above description is a configuration and method in which two pseudo molds 204 are arranged on the movable body in a state where they are adjacent to each other and the label 203 is wound around the two pseudo cores 205. However, in a mold having four or more molds, as shown in FIG. 27 (FIG. 27 shows an example of a two-stage configuration), the label delivery device 201 of the present embodiment is formed in a multistage shape without mutual interference. It is good also as a structure and a method which provide and can deliver at least 4 labels simultaneously.

In the above description, an insertion opening 204b is formed in the upper corner portion of each pseudo mold 204, and the label 203 is entered and held in the hollow portion 204a from the side where each adsorption member 219 does not interfere. However, the insertion opening formed in the pseudo mold is not limited to the upper corner portion, and an insertion opening is provided on the side of each pseudo mold arranged in the adjacent state, and the label is formed. The structure and method may be such that the adsorbing member holding the label enters the hollow portion through the insertion opening in a non-interfering state.
